OBJECTIVE:To provide a reference for clinical use of anti-tumor adjuvant drugs as is reasonable,effective and economical. METHODS:By retrospective investigation and analysis,the utilization of anti-tumor adjuvant drugs in the oncology department of our hospital during 2010 and 2013 was analyzed statistically in respect of the type,dosage form,consumption amount,DDDs,DDC,DUI etc. RESULTS:The anti-tumor adjuvant drugs in our hospital were dominated by injections,especial-ly domestic drugs,the consumption amount of which accounted for 80% of the total consumption amount of anti-tumor adjuvant drugs each year. The anti-tumor adjuvant drugs were mainly used for symptomatic treatment of various adverse reactions. Drug syn-chronization was relatively good each year,however,excessive use of individual drugs existed. CONCLUSIONS:Anti-tumor adju-vant drugs have relatively better synchronism in the drugs quantities and medication number. However,individual drugs have exces-sive use and other irrational use.

In the United States of America, the physician group practice has become one of the most common practice models, and has a relatively perfect and clear system of laws and regulations in its monitoring.In view of the policy side, the federal government has published the Stark Law to regulate the registration, properties, operation, service contents in details for the physician group practice.Taking the market side, it is practiced to protect the physician groups and medical practice behaviors through medical insurance policies.In China, the emergence of physician group has received widespread attention and concern.But since the short development time and unclear development path, the relevant laws and regulations for physician groups are still are not perfect.This paper aims to summarize the development and status quo of the American physician group as well as the regulations related to the groups` operating system, which will provide a good reference to China.The purpose is to provide policy recommendations for the standardized development and perfect regulations of physician groups in China.The following recommendations were put forward: improve the relevant laws and regulations;promote the establishment of the corresponding security policies;speed up and enhance the research and development of medical liability insurance;do continuous tracking and timely summarize practices.

Health management in the new era is significantly different from previous practices in terms of connotation, denotation, content, efficiency, and organizational framework. New health management systems utilize Internet technology, Internet of things, and artificial intelligence in order to manage individuals′ health in a comprehensive way. Reviewing the development of health management domestically and abroad, this article elaborates the connotations of health management and proposes that health management under the Healthy China strategy should focus on a combination of clinical care and prevention.

BACKGROUNDTo investigate the expression level and its clinical significance of the multi-drug resistance (MDR) associated protein in lung cancer specimens.

METHODSThe expression levels of Pgp, MRP, GST-π and TopoII of MDR associated protein were detected in 60 lung cancer samples and 30 paracancerous tissues by S-P immunohistochemistry method.

RESULTSThe positive rate of Pgp, MRP, GST-π and Topo II in the lung cancer tissues was 40.0% (24/60), 61.7% (37/60), 45.0% (27/60) and 81.7% (49/60) respectively, which was significantly higher than those in paracancerous tissues (P < 0.01). No significant correlation was observed among the expression of multi-drug resistance-related protein and TNM staging, pathological type, cell differention and lymph node metastasis status (P > 0.05).

CONCLUSIONSLung cancer has overexpression of multi-drug resistant-related genes during the oncogenesis. Combined detection of these genes may be useful for guiding the lung cancer chemotherapy.

Carrying out the optimal location selection of medical equipment in the medical community plays an important role in scientifically allocating equipment resources and improving the service capacity of medical community. Aiming at minimizing the operating cost of the location selection and configuration of the portable color Doppler ultrasound instrument in the county medical community and the shortest time spent on medical visits for residents, the authors established the total value objective function of the medical community configuration according to the value engineering method; and considered the relevant constraints such as distance, time and personnel quality, the mathematical model of optimal planning for the selection and configuration of portable color Doppler ultrasound equipment in county medical community was constructed. The empirical research results showed that based on the established constraints, after 5 000 iterations, the model output 5 relatively optimized allocation points among the 9 allocation points, and when the allocation number of each allocation point was 1, the total allocation value in the medical community reached the maximum. This study could provide a new idea and feasible method for the allocation of equipment resources of county medical community in China.

This article introduces the health management service specification for a chronic patient population. The concept of this specification comes from the whole process of people-centered and integrated health management of the chronic patient population. It is also based on the World Health Organization′s integrated chronic patient population management model. The completion of the specification has gone through several rounds of expert discussion in related fields in China. The contents include seven key links: suspect selection, clinical diagnosis, health assessment, intervention plan development, intervention plan implementation, follow-up, and health reassessment. It also includes establishing a professional team and developing a support system and mechanism of financing, compensation, and incentives. The specification aims at integrating regional health resources through standardizing service technology and scientific management concepts. It would help to improve the efficiency and quality of health management of chronic patient population in China, thereby reducing the economic burden of chronic diseases for patients and their families, and achieving the goal of improving residents′ health.

OBJECTIVE: To test the reliability and validity of the Chinese version of parenting sense of competence scale (PSOC) in Chinese mothers of preschool children, and to explore the perception of preschool children's mothers on their own parenting skills and their comfort of being a parent in Yanqing District of Beijing. METHODS: A cross-sectional survey was conducted using a convenience sample in 1 384 preschool children's mothers in Yanqing District of Beijing. SPSS 21.0 and Mplus 7.4 software were used for statistical analysis to test the structural validity, criterion related validity, internal consistency and split half reliability of the scale, and to analyze the score of the scale and its influencing factors. RESULTS: The PSOC had good reliability and validity. Exploratory factor analysis showed that each item of the PSOC had more than 0.4 factor loading in efficacy factor or satisfaction factor, and there was no double load phenomenon. Confirmatory factor analysis showed that the factor loadings ranged from 0.212 to 0.843 in efficacy factor and satisfaction factor, respectively. The goodness of fit test showed that all the fitting indexes were within the acceptable range, and the correlation between the effectiveness subscale and the satisfaction subscale was high. The Cronbach's α coefficient of the whole scale, the efficacy subscale and the satisfaction subscale were 0.872, 0.802, and 0.874, respectively. The Spearman-Brown coefficient of PSOC was 0.851. The average score of the whole scale, the efficacy subscale, and the satisfaction subscale were 72.33±11.31, 35.54±5.91, and 36.79±7.11, respectively, and the score of parenting competence in Chinese mothers of preschool children was influenced by the mother's educational level and the annual income of her family. CONCLUSION The PSOC has satisfactory reliability and validity in Chinese mothers of preschool children. It can be used as an evaluation instrument for measuring the parenting competency, self perceived efficacy and satisfaction in the mainland Chinese mothers of preschool children. The competency of preschool children's mothers in Yanqing District of Beijing is very good, which may be related to the higher education level of the mothers and the higher annual income of their families in this study.

ObjectiveTo study the inhibitory effect of Celastrus orbiculatus extract （COE） on gastric cancer cells， to clarify the specific mechanism of COE promoting the apoptosis of gastric cancer cells by affecting the mitochondrial structure and function， and to provide an experimental basis for the further development and clinical application of C. orbiculatus. MethodBrdu staining combined with flow cytometry and Annexin V-fluorescein isothiocyanate （AnnexinV-FITC） staining combined with flow cytometry were employed to detect the effects of COE （20， 40， 80 mg·L^-1） on the proliferation and apoptosis of gastric cancer cells， respectively. The changes in mitochondrial membrane potential were detected with JC-1 mitochondrial membrane potential assay kit. The expression of apoptosis-associated proteins including B-cell lymphoma-2 （Bcl-2）， B-cell lymphoma-xL （Bcl-xL）， Bcl-2-associated X （Bax）， and cysteine aspartutespecific protease-3 （Caspase-3） in gastric cancer cells was determined by Western blot. Transmission electron microscopy was employed to detect changes in the mitochondrial microstructure of gastric cancer cells exposed to COE. Western blot was employed to measure the expression of mitochondrial marker proteins ［superoxide dismutase 1 （SOD1）， voltage-dependent anion channel （VDAC）， prohibitin 1 （PHB1）， and heat shock protein 60 （HSP60）］ in gastric cancer cells. ResultCompared with the control group， COE （40， 80 mg·L^-1） inhibited the proliferation and promoted the apoptosis of gastric cancer cells （P<0.05）. Furthermore， COE reduced the mitochondrial membrane potential of gastric cancer cells. Compared with the control group， COE （20， 40， 80 mg·L^-1） up-regulated the expression of Bax and Caspase-3 which promoted apoptosis of gastric cells （P<0.05， P<0.01）， and COE at 40 and 80 mg·L^-1 down-regulated the expression of Bcl-2 and Bcl-xL which inhibited the apoptosis of gastric cancer cells （P<0.01）. The results of transmission electron microscopy showed that COE changed the microstructure of gastric cancer cells， which led to the appearance of vacuoles in the cell membrane and mitochondria and damaged the mitochondrial structure. Compared with the control group， COE （20， 40， 80 mg·L^-1） changed the expression of mitochondrial marker proteins. Specifically， it up-regulated the expression of SOD1 involved in stress response （P<0.05， P<0.01） and down-regulated that of VDAC， PHB1， and HSP60 associated with mitochondrial stability and permeability （P<0.01）. ConclusionCOE can significantly inhibit the proliferation and promote the apoptosis of gastric cancer cells. It may activate the mitochondrial apoptosis pathway by destroying the mitochondrial structure and function of gastric cancer cells.

ZNF804A rs1344706 has been identified as one of the risk genes for schizophrenia. However, the neural mechanisms underlying this association are unknown. Given that ZNF804A upregulates the expression of COMT, we hypothesized that ZNF804A may influence brain activity by interacting with COMT. Here, we genotyped ZNF804A rs1344706 and COMT rs4680 in 218 healthy Chinese participants. Amplitudes of low-frequency fluctuations (ALFFs) were applied to analyze the main and interaction effects of ZNF804A rs1344706 and COMT rs4680. The ALFFs of the bilateral dorsolateral prefrontal cortex showed a significant ZNF804A rs1344706 × COMT rs4680 interaction, manifesting as a U-shaped modulation, presumably by dopamine signaling. Significant main effects were also found. These findings suggest that ZNF804A affects the resting-state functional activation by interacting with COMT, and may improve our understanding of the neurobiological effects of ZNF804A and its association with schizophrenia.
