Polymyositis (PM) and dermatomyositis (DM) are inflammatory myopathies and slowly advanced of unknown etiology that affect the skeletal muscles.With the advancement of the constant research on the disease and use of new technology,people have a penetrating realization about the pathogenesis. The disease is thought to be associated with autoimmune as well as nonimmune mechanism. By now, there is no overall summary on the newest advancement of the pathogenesis.We summarized the progress on the pathogenesis of the disease in order to make it more clear to physicians.

Ultrasound molecular imaging has become one of the hotspots of molecular imaging because of its advantages of non-invasion, non-radiation, repeatability and real-time dynamic imaging. The key of imaging is to select the appropriate target and ligand to bind to the ultrasound contrast agent. The formation of blood vessels in the development of tumor is a significant feature. Vascular endothelial growth factor receptor (VEGFR) is an important specific molecule on tumor vascular endothelial cells, and which can be used as a target for tumor ultrasound imaging. In recent years, many scholars have carried out related studies on the imaging of ultrasound molecules targeting VEGFR. This paper reviewed the mechanism and application of tumor ultrasound molecular imaging with VEGFR as target in recent years.

Objective To observe the clinical efficacy of S-1 plus oxaliplatin (SOX) in neoadjuvant chemotherapy for patients with local advanced gastric carcinoma.Methods Clinicopathological data of 68 patients with local advanced gastric cancer were retrospectively analyzed and enrolled as treatment group.All the patients in the treatment group achieved 3-4 cycles chemotherapy of SOX regimen preoperatively.Outcomes of tumor remission after neoadjuvant chemotherapy were evaluated according to RECISI1.1 criteria.Meanwhile,70 patients who underwent operation directly after pathological diagnosis of local advanced gastric cancer during the same period were recruited as control group.Resection rate,R0 resection rate,postoperative complications rate and postoperative progression free survival(PPFS) time were compared between the two groups.Results In the treatment group,after neoadjuvant chemotherapy,4 cases (5.9％) achieved complete renission,36 cases (52.9％) achieved partial remission.Meanwhile,the numbers of cases with stable disease and progressive disease were 15 cases(22.1％) and 13 cases (19.1％) respectively.The objective remission rate and disease control rate in the treatment group were 58.8％ and 80.9％ respectively.The tumor resection rate,R0 resection rate,postoperative complications rate in the treatment group were 92.6％,85.3％ and 14.7％ respectively.The R0 resection rate in the treatment group was higher than that in the control group,the difference was statistically significant(x2 =8.042,P ＜ 0.05).However,the differences of tumor resection rate and postoperative complications rate between the two groups were not statistically significant (x2 =1.711,0.673,all P ＞ 0.05).The median time of PPFS in the treatment group and the control group was 36 months and 30 months respectively,there was statistically significant difference in PPFS between the two groups (x2 =4.049,P ＜ 0.05).Conclusion The neoadjuvant chemotherapy of S-1 plus oxaliplatin for local advanced gastric carcminoma has satisfactory short-term effect and can also improve PPFS.However,further investigation is required to observe the effect of this neoadjuvant chemotherapy regimen on postoperative overall survival.

OBJECTIVE:To establish the ultraviolet visible spectrophotometry(UV-VIS)for the determination of Fe content in iron dextran preparations.METHODS:Under the acidic condition,Fe~(3+)was dissociated from iron dextran solution by heating,then Fe~(3+)was deoxidized into Fe~(2+)by hydroxylamine hydrochloride,and red Fe~(2+)-orthophenanthroline complex was formed through combination with o-phenanthroline.The content of the Fe~(2+)-orthophenanthroline complex was determined by UV-VIS at a wavelength of 510 nm.RESULTS:The linear range of Fe~(2+)was 0.5～4.0?g?mL~(-1)(r=0.999 9). The average recoveries of two preparations(tablets and injection)of iron dextran were 99.8%(RSD=0.52%)and 99.7% (RSD=0.44%),respectively.CONCLUSION:The UV-VIS method is simple,accurate in results and applicable for the determination of iron dextran preparations.

Moyamoya disease is a progressive cerebrovascular occlusive disease, which is characterized by the formation of abnormal vascular network at the brain base. It is an important cause of stroke in children and adults. Now, the etiology of moyamoya disease is not clear. This article reviews its pathogenesis from 3 aspects, including genetic factors, angiogenesis, and immune inflammation.

Objective To discuss the application effect of TCM constitution recognition on TCM chronic disease refining health management for type 2 diabetes mellitus.Methods Totally 140 outpatients with type 2 diabetes mellitus from Chaoyangmen Community Health Center were selected and divided evenly into two groups after TCM constitution assessment. The study lasted for 2 years (1st August 2013–31st July 2015). The control group (70 cases) received diabetes community health management. In addition to routine community health management, TCM constitutional management was also administrated in the intervention group. The latter group received medicine, food, sport guidance according to the results of TCM constitution assessment. The blood glucose, blood lipid, BMI and waist-hip ratio of the two groups were monitored, and the self-management and life quality of patients were evaluated. Results After the intervention, significant improvement was found for fasting blood glucose, 2 h postprandial blood glucose, BMI, waist-hip ratio and blood lipid both in the control group and the intervention group, and the improvement in the intervention group was more obvious than the control group (P<0.05). The whole level of self-management and life quality was greatly increased in both groups, while improvement of the intervention group was much higher than the control group (P<0.05).Conclusion Integrated application of TCM constitutional theory in TCM chronic disease refining health management for type 2 diabetes mellitus will contribute to improving patients’ self-management, changing their clinical symptoms and finally improving their life quality.

Objective To investigate the optimal surgical timing for rib internal fixation.Methods The clinical data of 143 patients with rib fracture were retrospectively analyzed.The patients were divided into early phase fixation group (62 cases) and late phase fixation group (81 cases) according to the time from trauma to internal fixation.The ratio blood lose and body surface area,pulmonary complications and the changes of C reactive protein level before and 5 days after operation were recorded and compared.Results All the patients were healing.The median C reactive protein before operation in late phase fixation group was 45 mg/L,in early phase fixation group was 23 mg/L,there was statistical difference (P ＜ 0.01).The ratio blood lose and body surface area in early phase fixation group was (334.19 ± 37.53) ml/m2,the rate of pulmonary complications was 22.6％(14/61),in late phase fixation group was (438.99 ± 55.24) ml/m2 and 38.3％ (31/81),there were statistical differences (P ＜ 0.01 or ＜ 0.05).The median C reactive protein 5 days after operation in early phase fixation group was 189 mg/L,in late phase fixation group was 258 mg/L,there was statistical difference (P ＜ 0.05).Conclusion Early phase (72 hours) rib internal fixation is expected to reduce patient trauma of systemic reactions,reduce the incidence of bleeding and pulmonary complications.

Thrombolytic therapy for ischemic stroke has received wide attention. Now the thrombolytic therapy mainly includes intervenous thrombolysis, intra-arterial thrombolysis, combination of intravenous and intra-arterial thrombolysis, and mechanical thrombolysis. The review mainly presents the recent progress in this field.

The new medical reform policy situation,the professional development of health management should follow the principle of scientific development to achieve three-dimensional models of development.Three-dimensional-style development should focus on the realization of the subject-object interaction,full management,all-round construction,double-entry-style positioning,and compound training of personnel.And through the three-dimensional development strategy we should seek to promote the health management leaps and bounds.
