  • An Early Pregnant Chinese Woman with Cerebral Venous Sinus Thrombosis
           Succeeding in Induction of Labor in the Second Trimester
    • Abstract: Publication date: December 2018Source: Chinese Medical Sciences Journal, Volume 33, Issue 4Author(s): Xuefang Zhang, Zhenyu Zhang, Nan LiAbstractCerebral venous sinus thrombosis (CVST) is a rare condition in early pregnancy. A 22-year-old Chinese woman at 10 weeks of pregnancy requested induced abortion and was diagnosed as CVST for a severe headache accompanying with nausea and vomiting. The patient was treated successfully with anticoagulation, followed by amniocentesis, and finally succeeded in induction of labor safely. The diagnosis, treatment and prognosis for this rare condition are discussed in this paper.
  • Combined Effects of Chronic Obstructive Pulmonary Disease and Depression
           on Spatial Memory in Old Rats
    • Abstract: Publication date: December 2018Source: Chinese Medical Sciences Journal, Volume 33, Issue 4Author(s): Cui Cai, Changqing Xu, Hualiang Jin, Bei LiObjectiveTo investigate the combined effects of chronic obstructive pulmonary disease (COPD) and depression on spatial memory in old rats, aiming to better understand the comorbidity of the two diseases in geriatric patients.MethodsThe SD rats were assigned into five groups: adult control group (n=6), elderly control group (n=6), elderly COPD group (n=6), elderly depression group (n=6) and elderly COPD with depression group (n=6). Smoking and chronic unpredictable mild stress (CUMS) with solitary support were used to induce COPD model, depression model, respectively, and the both were applied for the comorbidity model. Learning and memory deficits were assessed by Morris water maze (MWM) test. The activity of superoxide dismutase (SOD) and the content of malondialdehyde (MDA) in serum and hippocampus tissue were determined by Xanthinoxidase method and Thiobarbituric acid reaction (TBAR) method, respectively.ResultsThe results of pulmonary histology, lung function, open-field test and sucrose consumption demonstrated the comorbidity models of COPD and depression in elderly rats were successfully established using smoking and CUMS with solitary support. Compared with the elderly control group, the group of COPD with depression had obviously longer time of latency and longer travel distance to reach the platform in MWM test (LSD-t=-10.116, p=0.000; LSD-t=-6.448, p=0.000). The SOD activity in serum and hippocampus decreased significantly (LSD-t=2.629, P=0.014; LSD-t=2.215, P=0.044) and the MDA content in serum and hippocampus increased significantly (LSD-t=-2.140, P=0.042; LSD-t=-2.070, P=0.049) in elderly COPD with depression group.ConclusionsCOPD in comorbidity of depression could induce spatial memory deficit in old rats. The mechanisms might be related to the overloaded and free radical metabolic imbalance. These results suggest a potential therapeutic target for comorbidity of COPD and depression in geriatric patients.
  • Longitudinal Measurement of Hemodynamic Changes within the Posterior Optic
           Nerve Head in Rodent Nonarteritic Anterior Ischemic Optic Neuropathy
    • Abstract: Publication date: December 2018Source: Chinese Medical Sciences Journal, Volume 33, Issue 4Author(s): Jin Ma, Ting Chen, Yiwei Wang, Chan Zhao, Donghui Li, Meng Wang, Linyang Gan, Yong ZhongObjectiveTo assess the in vivo dynamic blood flow features of posterior optic nerve head (ONH) in rat model of nonarteritic anterior ischemic optic neuropathy (rNAION).MethodsrNAION was established with Rose Bengal and argon green laser in Sprague-Dawley rats. Fundus photography and fundus fluorescein angiography (FFA) were performed to assess the dynamic changes of optic disc in morphology in 90 days and in blood perfusion in 3 hours after the induction of disease. Histological examinations were performed to evaluate the success of modeling. The dynamic blood flow kinetics of posterior ONH in rNAION were measured by Laser Doppler Flowmetry (LDF) on the day 3, 7, 14, 21, and 40 after the disease induction. One-way ANOVA, Student's t-test and Bonferroni adjustment were used for multiple comparisons of kinetic measurements of blood flow.ResultsOptic disc edema and subsequent resolution associated with the development of optic disc pallor were observed in rNAION. FFA showed that the optic disc was hypofluorescence in the early phase and hyperfluorescence in the late phase. Histological studies suggested edema and loosened tissues of ONH, loss of retinal ganglion cells (RGCs), optic nerve substance and gliosis. Compared to the naive rats, the blood flow kinetics of posterior ONH in rNAION significant reduced at each time point after modeling (F=175.06, P
  • Current Technologies of Synthetic Biosensors for Disease Detection:
           Design, Classification and Future Perspectives
    • Abstract: Publication date: December 2018Source: Chinese Medical Sciences Journal, Volume 33, Issue 4Author(s): Xue Chen, Yi Lv, Rongqian WuAbstractSynthetic biology aims to endow living cells with new functions by incorporating functional gene networks into them. By overexpressing, blocking and rewiring native gene pathways, synthetic biologists have harnessed this promising technology to reprogram cells to perform diverse tasks such as drug discovery, biopharmaceutical manufacturing, gene therapy and tissue engineering, etc. In this review, we focus on current technologies of synthetic biosensors for disease detection. We start with the design principle of synthetic biosensors. Then we move towards the characteristics of simple synthetic biosensors, which can respond to a single input signal, and complex synthetic biosensors including Boolean gate biosensors, cascade biosensors, time-delay biosensors, oscillator biosensors and hysteretic biosensors, which can respond to more than two input signals and perform complex tasks. Synthetic biosensor has showed great potential in disease detection, but it is still in its infancy stage. More efforts should be made in identifying and constructing clinically relevant regulation systems. Computational tools are also needed in the design process in order to guarantee the precision of the synthetic biosensor. The ultimate goal of a synthetic biosensor is to act as a therapeutic sensor-effector device that connects diagnostic input with therapeutic output and therefore provides all-in-one diagnostic and therapeutic solutions for future gene- and cell-based therapies.
  • Individualized Aromatherapy in End-of-Life Cancer Patients Care: A Case
    • Abstract: Publication date: December 2018Source: Chinese Medical Sciences Journal, Volume 33, Issue 4Author(s): Qian Liu, Xiaohong Ning, Lei Wang, Wei LiuAbstractAs one of the methods of palliative care, aromatherapy has been applied gradually in clinical nursing work in China in recent years. Through aromatherapy, terminal cancer patients can get not only relieves of physical symptoms, but also spiritual relaxation and peace, thus have improved quality of life at the end stage. In this paper, we report in detail about how aromatherapy was applied for symptom control in a cancer patient with unknown primary malignancy and multiple metastasis and its effects on the terminal life of this patient.
  • Recognition of Palliative Care in Chinese Clinicians: How They Feel and
           What They Know
    • Abstract: Publication date: December 2018Source: Chinese Medical Sciences Journal, Volume 33, Issue 4Author(s): Yirong Xiang, Xiaohong NingObjectiveTo investigate doctors’ feelings when providing medical care to end-stage patients, and their understanding as well as reflection about theoretical concepts of palliative medicine.MethodsQuestionnaires were delivered through a social networking platform to 1500 clinicians of different specialties in 10 proviences of China. It covered issues of background information, self-assessment of familiarity to palliative care, prior training history, emotional attitude toward end-stage patients, and the reflections on clinical practice. Logistic regression analysis and chi-square test were used to analyse the categorical variables.ResultsThere were 379 clinicians who completed the questionnaires and submitted successfully. Among them, 66.8% (253/379) had attended palliative care training courses more than twice; 66.8% (253/379) clinicians percieved powerless feeling when facing end-stage patients. We found that the education on palliative medicine was significantly associated to doctors’ better comprehension on the concept of palliative care (OR=6.923, P=0.002). Doctors who were more familiar with palliative medicine were less likely to perceive powerless feelings (χ2=13.015, P
  • Running a Volunteer Program for Palliative Care in a Chinese Hospital: Our
           Practice and Experience
    • Abstract: Publication date: December 2018Source: Chinese Medical Sciences Journal, Volume 33, Issue 4Author(s): Xiaohong Ning, Jie Li, Yirong XiangAbstractThe establishment and development of volunteer team are very important in the whole process of palliative care. The concept and practice of palliative care have been developed in Peking Union Medical College Hospital (PUMCH) since the end of 2012. Great progress has been made in different aspects. Volunteers play an extremely important role in the development of palliative care in PUMCH. The whole work began with the establishment of volunteer teams. This article introduces the process of the establishment and development of palliative care volunteer team in PUMCH, aiming to provide practical references for hospitals in mainland China to develop their own palliative care volunteer team.
  • Implement the Palliative Care in Medical Practice of a Tertiary
           Comprehensive Hospital in China
    • Abstract: Publication date: December 2018Source: Chinese Medical Sciences Journal, Volume 33, Issue 4Author(s): Xiaohong NingAbstractThe locations and modalities of palliative care services to patients with severe/end-stage illness can be diverse, ranging from general hospitals to home-based care. The concept of palliative care hasn't been fully applied to medical practice by care providers in mainland China, where the seriously ill or terminal patients mainly receive medical care in hospitals. The implementation of palliative care in medical practice has developed greatly in Peking Union Medical College hospital in terms of clinical patient care, education, and research. This article gives an overview of it, and the experiences in team building, promotion, support seaking and fund raising were also discussed in this article. We hope to explore an effective dilivering model of palliative care for end-stage patients that is adaptive to Chinese culture and social environment.
  • Value-based Practice: Integration of Cancer Rehabilitation and Palliative
           Care in Oncology Services
    • Abstract: Publication date: December 2018Source: Chinese Medical Sciences Journal, Volume 33, Issue 4Author(s): Yi ZhuAbstractValue-based care model has been evolving to organize medical services around the patient and provide the full cycle of care for a medical condition. The full cycle of care model encompasses inpatient, outpatient, rehabilitation as well as supportive care such as palliative care and nutrition support. Cancer rehabilitation and palliative care have emerged as two important parts of value-based practice for oncology patients. More clinical evidence suggests that early intervention of oncology rehabilitation program and palliative care are likely to improve the patient outcome and reduce the overall medical cost for the patient and his or her family as well as for medical service providers. Although interest has been raised in Chinese oncologists, but effectiveness of incorporating these two services in clinical practices has not been adequately demonstrated. An understanding of scope of cancer rehabilitation and palliative care may help facilitate the integration of both into the oncology care continuum in efforts to improve patients' physical, psychological, cognitive, functional health and quality of life.
  • Hospice and Palliative Care in Mainland China: History, Current Status and
    • Abstract: Publication date: December 2018Source: Chinese Medical Sciences Journal, Volume 33, Issue 4Author(s): Xiaohong NingAbstractThe concept of End-of-Life Care (EOLC) came into China in the late 1980s. However, hospice and palliative care in medical practice develope slowly. In recent years, profesionals, patients and their families, as well as government begin to attach importance to it. There is a hospice and palliative care movement now in China. This article gives an overview of the progress and the current status in multiple aspects of hospice and palliative care in mainland China, and points out the barriers and challenges for its further development in the future.
  • Imaging Diagnosis of Type III Choledochal Cyst: A Case Report
    • Abstract: Publication date: September 2018Source: Chinese Medical Sciences Journal, Volume 33, Issue 3Author(s): Ping Li, Liang Zhu, Xuan Wang, Huadan Xue, Xin Wu, Zhengyu JinAbstractCholedochocele is a congenital abnormality of the biliary system, which characterized by a cystic dilatation of intramural segment of the distal common bile duct. Choledochocele manifests as cystic lesions in the duodenal lumen and resembles duodenal duplication cysts in imaging. We reported a patient with choledochocele. Magnetic resonance cholangiopancreatography showed a thin-walled sac in the duodenal cavity and a fine tubular structure connecting with the end of the common bile duct. Magnetic resonance cholangiopancreatography is a noninvasive and convenient technique in the diagnosis of choledochocele.
  • Multi-parametric MRI Diagnoses Cerebellar Hemangioblastoma: A Case Report
    • Abstract: Publication date: September 2018Source: Chinese Medical Sciences Journal, Volume 33, Issue 3Author(s): Zhiye Chen, Mengqi Liu, Shengyuan Yu, Lin MaAbstractWe performed contrast-enhanced T2 fluid-attenuated inversion recovery (T2-FLAIR) and dynamic contrast enhanced MRI to illustrate the imaging characteristics of one case of hemangioblastoma. T2-FLAIR showed a large cyst located in the right cerebellum with mural nodule. The intensely enhancing cyst wall was observed on enhanced T2-FLAIR images acquired from 5.6 to 23 minutes after contrast administration, and quantitative dynamic contrast enhanced-MRI demonstrated that both the cyst wall and mural nodule presented high Ktrans, Kep and Ve values compared with the contralateral normal cerebellar tissues. The cyst showed gradual enhancement and reached the highest signal intensity at 67 minutes after contrast administration on enhanced T2-FLAIR images. In conclusion, early enhancement of cyst wall on T2-FLAIR might be the characteristic imaging findings for cystic hemangioblastoma, which may assist in the diagnosis of hemangioblastoma preoperatively.
  • Treatment of Skin Reaction Induced by Nivolumab Combined with Radiotherapy
           in Non-small Cell Lung Cancer: A Case Report
    • Abstract: Publication date: September 2018Source: Chinese Medical Sciences Journal, Volume 33, Issue 3Author(s): Zhimei Zhao, Shichao Liu, Xiajuan Xu, Zhongfa Zhang, Keke Nie, Youxin JiAbstractSkin reaction or dermatological toxicities induced by immunotherapy is common. It usually manifests skin rash or erythema and can be cured by skin lotion or steroid. Nivolumab, a human IgG4 programmed cell death protein 1 (PD-1) inhibitor, blocks T cells activation preventing signal and allows the immune system to clear cancer cells. Nivolumab was approved in the second-line therapy in squamous cell lung cancer by FDA, with less than 10% unusual skin reaction, like sensory neuropathy, peeling skin, erythema multiforme, vitiligo, and psoriasis. Radiotherapy could aggravate this skin reaction through inflammatory response and promotion of immunity. The combined treatment of anti-PD-1 and radiotherapy represented a new promising therapeutic approach in many studies, but the risk of side effects may be high. We reported a patient with advanced squamous cell lung cancer who suffered from serious skin immune-related adverse events when he was treated with nivolumab and radiotherapy. The immune overreaction of the treatment of anti-PD-1 treatment and radiotherapy might cause these serious skin adverse events. Our report warranted careful workup to reduce the risk of side effects by combinative therapy with anti-PD-1 and radiotherapy.
  • Landscape of PD-1/PD-L1 Regulation and Targeted Immunotherapy
    • Abstract: Publication date: September 2018Source: Chinese Medical Sciences Journal, Volume 33, Issue 3Author(s): Jieming Ni, Anping NiAbstractProgrammed cell death protein 1 (PD-1)/programmed death ligand 1 (PD-L1) is a significant immune checkpoint, and the dysfunction of this axis contributes to tumor metastasis and immune escape. PI3K/Akt/mTOR and MAPK signal network induces PD-1/PD-L1 expression and facilitates tumor progression. Transcriptional factors such as hypoxia induced factors, PTEN, p53, CDK5, BRD4, STAT modulate PD-1/PDL1 expression. PD-1/PD-L1 level is also regulated via epigenetic and post-translational manner. The underlying mechanisms mentioned above may provide potential targets for tumor treatment. At present, the combination therapy of PD-1/PD-L1 monoclonal antibodies plus small molecular inhibitors has achieved good outcomes in tumor treatment.

We reviewed the medical records and summarized the clinical, laboratory and imaging characteristics of these cases, and compared the results on admission with those determined before discharge.ResultsForty-eight (49.0%) patients developed HAPE at the altitude of 2800 m to 3000 m. Ninty-five (96.9%) patients were man. Moist rales were audible from the both lungs, and moist rales over the right lung were clearer than those over the left lung in fourteen patients. The white blood cells [(12.83±5.55) versus (8.95±3.23) × 109/L, P=0.001)] as well as neutrophil counts [(11.34±3.81) versus (7.49±2.83) × 109/L, P=0.001)] were higher, whereas the counts of other subsets of white blood cells were lower on admission than those after recovery (all P
  • Urinary Myeloperoxidase to Creatinine Ratio as a New Marker for Diagnosis
           of Urinary Tract Infection
    • Abstract: Publication date: September 2018Source: Chinese Medical Sciences Journal, Volume 33, Issue 3Author(s): Mingjian Bai, Jing Feng, Guowei LiangObjectiveTo determine whether urinary myeloperoxidase to creatinine ratio (MCR) can serve as a marker for diagnosis of urinary tract infection (UTI).MethodsPatients suspected of UTI were consecutively enrolled and further divided into the culture positive and the sterile groups according to urine culture results. Subsequently, MCR, white blood cell (WBC) and bacteria in the urinary samples from patients were detected and compared between the two groups.ResultsFinally, 253 patients were enrolled including 157 urine culture positive patients and 96 urine culture negative patients (sterile group). After logarithmic transformation in 2 as the base, the MCR, WBC, and bacteria were separately presented as log2MCR, log2WBC (quantitative), and log2bacteria. The values of log2MCR (8.6±2.5 vs. 5.4±1.5, t=−12.453, P=0.001), log2WBC (quantitative) (8.0±2.5 vs. 5.2±1.8, t=−10.332, P=0.001), log2bacteria (11.4±2.5 vs. 8.2±2.8, t=−9.297, P=0.001) and WBC (semi-quantitative) [2 (interquartile range 1, 3) vs. 1 (interquartile range 0.5, 1), Z=−7.580, P=0.001] showed significant difference between the urine culture positive group and the sterile group. Among the urine culture positive group, the values of log2MCR of the gram positive and gram negative subgroups were 7.2±2.5 and 9.0±2.4 (t=4.016, P=0.001), respectively. The correlation between log2MCR and log2WBC (quantitative), log2bacteria, WBC (semi-quantitative) was 0.708 (Pearson correlation, P=0.001), 0.381 (Pearson correlation, P=0.001), and 0.606 (Spearman correlation, P=0.001), respectively.ConclusionsMCR is positively correlated with WBC counts and could be served as a promising biomarker for diagnosis of UTI. MCR could be even used for initial inference of infectious bacteria types of UTI.
  • RNA-binding Protein UNR Promotes Glioma Cell Migration and Regulates the
           Expression of Ribosomal Protein L9
    • Abstract: Publication date: September 2018Source: Chinese Medical Sciences Journal, Volume 33, Issue 3Author(s): Ningyu Tian, Yingjiao Qi, Yan Hu, Bin Yin, Jiangang Yuan, Boqin Qiang, Xiaozhong Peng, Wei HanObjectiveTo investigate the role of RNA binding protein—upstream-of-N-Ras (UNR) in the development of glioma and its molecular mechanism.MethodsFirst, bioinformatics analysis of CGGA database was performed to detect UNR expression level and prognosis of patients with glioma. Western blot and real-time PCR were used to detect UNR expression level in glioma cell lines and tissues. Next, UNR siRNAs were transfected in glioma cells, and MTS assay and scratch wound-healing assay were used to detect changes in cell proliferation and migration. Then, the candidate UNR target mRNAs were identified by analyzing the sequencing data of UNR iCLIP-seq, RNA sequencing and ribosome profiling databases of human melanoma. RNA immunoprecipitation and biotin pull-down assays were used to identify the UNR target mRNAs in glioma cells. Finally, western blot was used to detect the effect of UNR knockdown on ribosomal protein L9 (RPL9) and RPL9 protein expression level in glioma cell lines. RPL9 siRNA was transfected in A172 and T98G and the expression of vimentin in the cells was detected with western blot.ResultsBioinformatics analysis showed that UNR mRNA expression level was significantly higher in high-grade glioma [Grade II (n=126), Grade III (n=51), Grade IV (n=128), P
  • Resuscitation of Septic Patients with Target-and-endpoint Protocol: A
           Retrospective Study from a Chinese Tertiary Hospital ICU
    • Abstract: Publication date: September 2018Source: Chinese Medical Sciences Journal, Volume 33, Issue 3Author(s): Hongmin Zhang, Xiaoting Wang, Qing Zhang, Dawei LiuObjectiveTo investigate the effect of target-and-endpoint protocol on the resuscitation of septic patients.MethodsThis is a retrospective study performed at the Peking Union Medical College Hospital Intensive Care Unit. We enrolled 545 septic patients who needed vasopressors on at least the first day of ICU admission. The general characteristics, blood lactate level, mean arterial pressure (MAP), central venous pressure (CVP) and saturation of central venous oxygen (ScvO2) at admission and 6, 24 hours after admission were collected. The parameters at different time points were compared. Lactate clearance rate and in-hospital mortality were analyzed.ResultsThe 6-hour lactate clearance rate was 21.6% (IQR, 8.6%–39.0%), and in-hospital mortality was 9.4%. For patients with low CVP values (
