Gastric cancer is the fourth most common cancer and is the second leading cause of cancer death worldwide. Gastric cancer is usually in advanced stage at diagnosis, without opportunity for curative resection. Chemotherapy is the major treatment for advanced gastric cancer (AGC), and other treatments include palliative surgery, radiotherapy, chemotherapy, biologic and immunologic therapy as well as Chinese medicine. Palliative therapy is used to reduce tumor load or complication occurrence, while radiotherapy is effective for locoregionally advanced gastdc cancer. At present, chemotherapy plays a leading role in AGC treatment and has a palliative effect on symptomatic patients. For advanced or metastatic gastric cancer, chemotherapy has always been the focus of studies. Results of studies of FAX, ECF/DCF regimens and Phrase ill clinical trials of REAL-2, ML17032 and SPIRITS have been released. With the application of EOX, XP, S-1/CDDP, IF, FOLFOX and XELOX regimens, the outcomes of advanced gastdc cancer are improved. However, there is no standard regimen accepted as supedor over others. Biologic and immunologic therapy are beneficial supplements to surgery, chemotherapy and radiotherapy, but are not yet the mainstream. All of these treatments have obvious side effects. Other comprehensive methods are of equal importance, such as Chinese herbal medicine, acupuncture and moxibustion, and psychological intervention. Combined with western medicine, the above methods have certain merits in relieving clinical symptoms, reducing toxicity,increasing effectiveness, improving quality of life, preventing metastasis and recurrence, reversing multidrug resistance of tumor cells, and curing ascites and managing cancer pain.

Objective To observe the effect of Jingui Shenqi Wan (JSW) on the content of calcium channel protein CaV1.3 of guinea pigs with ototoxic deafness induced by gentamicin (GM). Methods Forty healthy guinea pigs were randomly divided into normal group, model group and high-, middle-, and low-dose JSW treatment groups. The model group was given intramuscular injection of GM ( 120 mg/kg) per day for 10 continuous days. The high-, middle-, and low-dose JSW treatment groups were given intramuscular injection of GM (120 mg/kg) and intragastric administration of JSW in the dosage of 20.3, 13.5, 6.08 g·kg-1·d-1 respectively per day for 10 days. Immuno histochemistry was used to detect the mean optical density value of CaV1.3 expression in cochlear hair cells. Results There were significant differences of the optical density value of CaV1.3 in cochlear hair cells between the model group and normal group (P<0.01), and between the model group and high-dose JSW treatment group (P<0.05). Conclusion JSW has certain effect on preventing and treating guinea pig with ototoxic deafness induced by GM, thus to protect the hearing function.

Cerebral smal vessel disease (CSVD) accounts for 25 to 30% of al strokes. It is a main cause of vascular cognitive impairment. Because of cerebral smal vessels can not easily be directly observed and studied in vivo and on imaging, so the term CSVD is generaly used to describe a syndrome of clinical, cognitive, neuroimaging, and neuropathological changes, and not focus on the pathological changes of the smal vessel wal itself that caused these syndromes. This article reviews the advances in research on CSVD, particularly its pathological changes of vessel wals.

Objective Joint-PhD program is an effective way to cultivate international creative talents.Survey on intrinsic value factors of this mode is significant to improve the quality of medical education.Methods According to the questionnaire results and reports of 104 medical doctorates who attended the Joint-PhD program in PUHSC,Baldrige Performance Excellence was taken as theoretical framework.Results It showed that index influencing the quality of Joint-PhD education include social responsibility;stakeholders' expectation and market requirements;information and knowledge management support and so on.Conclusion In the process of doctoral education,advocating value of social responsibility,paying attention to the expectations of stakeholders,and attaching importance to the validity of education management services help to understand the intrinsic value of the quality management from the top universities in the world,in order to fundamentally improve the quality of doctoral education.

Objective To compare the differential expression of MRP1 in human breast cancer sensitive cells (MCF-7/S)and resistant cells (MCF-7/TAM、MCF-7/ADR), and to preliminary distinguish whether there is a common mechanism between breast cancer cells resistant to tamoxifen (TAM) and to adriamycin(ADR).Methods We detected the expression of MRP1 gene and MRP1 protein in the three breast cancer cells by using the methods of real-time fluorescence quantitative PCR, and Western blot respectively.Results The expression of MRP1 gene in MCF-7/TAM and MCF-7/ADR cells was (2.63 ± 0.18) and (8.38 ±0.76) times of MCF-7/S cells respectively, which was significantly different (P1=0.004,P2=0.003). The expression of MRP1 protein in MCF-7/TAM and MCF-7/ADR cells was higher than MCF-7/S cells,which was consistent with the trend of MRP1 gene. Conclusions The high expression of MRP1 may be the common mechanism in breast cancer cells resistant to TAM and ADR.

O-GlcNAcylation is the addition of a single N-acetylglucosamine(GlcNAc)moiety to the hydroxyl groups of serine or threonine residues of nuclear and cytoplasmic proteins. The transcription factors, kinases of the metabolic pathways and some cytoplasmic enzymes can be O-GlcNAcylated to affect cell transcription, signal transduction, cell metabolism and other biological functions. Abnormal glucose metabolism of tumors has been a hotspot in the research field of tumor pathogenesis and therapeutic targets recently. O-GlcNAclation regulates the glucose metabolism of tumor by affecting the activity of kinases in the metabolic pathway, which is closely associated with the abnormal glucose metabolism of tumor. The abnormal O-GlcNAcylation is one of the potential reasons of cancer. In this review, in order to provide a theoretical reference for developing anti-tumor targets and drugs targeting O-GlcNAc modification, we briefly summarized how O-GlcNAcylation regulated glucose metabolism on glucose metabolism, glucose uptake, glycolysis, pentose phosphate pathway and tricarboxylic acid cycle in cancer cell.

The dysfunction of subthalamic nucleus is the main cause of Parkinson's disease. Local field potentials in human subthalamic nucleus contain rich physiological information. The present study aimed to quantify the oscillatory and dynamic characteristics of local field potentials of subthalamic nucleus, and their modulation by the medication therapy for Parkinson's disease. The subthalamic nucleus local field potentials were recorded from patients with Parkinson's disease at the states of on and off medication. The oscillatory features were characterised with the power spectral analysis. Furthermore, the dynamic features were characterised with time-frequency analysis and the coefficient of variation measure of the time-variant power at each frequency. There was a dominant peak at low beta-band with medication off. The medication significantly suppressed the low beta component and increased the theta component. The amplitude fluctuation of neural oscillations was measured by the coefficient of variation. The coefficient of variation in 4-7 Hz and 60-66 Hz was increased by medication. These effects proved that medication had significant modulation to subthalamic nucleus neural oscillatory synchronization and dynamic features. The subthalamic nucleus neural activities tend towards stable state under medication. The findings would provide quantitative biomarkers for studying the mechanisms of Parkinson's disease and clinical treatments of medication or deep brain stimulation.
