Retinal detachment (RD) is one of the most common sight-threatening retinal diseases.Visual acuity is not always restored after successful reattachment of the retina.Photoreceptor cell death has been thought to be the major cause of vision loss after RD through various pathways and their interactions,including caspase-dependent apoptosis,endoplasmic reticulum stress-induced apoptosis and non-apoptotic death forms,such as necroptosis,autophagy,and so on.Based on the understanding of the mechanism of photoreceptor cell death after RD,current efforts on combinatorial inhibition of multiple death pathways,targeting upstream molecules and enhancement of intrinsic neuroprotection would help us to protect photoreceptors effectively and improve visual acuity of RD patients.This review summarized current opinions on mechanisms of photoreceptor cell death and the potential treatment strategies.

OBJECTIVE: To study and collate the literature on rare diseases in domestic and abroad, and comparative analysis, provide a scientific basis for the domestic rare diseases research. METHODS: Retrieved the Web of Science, China National Knowledge Infrastructure from January 2011 to June 2016 published literature about rare diseases. RESULTS: Through the screening of literature, finally determine the 200 articles for analysis. It is divided into seven research directions: rare diseases policy research, rare diseases legal and regulatory research, rare diseases medical social security study, orphan drugs availability research, orphan drugs economic evaluation study, orphan drug development research, rare diseases defined standard research. CONCLUSION: Rare diseases policy research is the focus of research both domestic and abroad. Compared with foreign countries, the domestic research on the availability and economic evaluation of orphan drug is less, especially the economic evaluation research is almost blank. It is suggested that the researchers study the multiple aspects of rare diseases and drugs, and to provide the basis and reference for build rare disease policy in China. In addition to the field of rare diseases research, rare diseases drugs face many difficulties in pharmaceutical research, production and supply. The precondition to solve these problems is the nation formulate specific policies and regulations for rare diseases, and then clear the official definition standards of rare diseases, establish relevant policies to encourage pharmaceutical companies to develop rare diseases drugs.

Patients with SAP have a hypermetabolic and hypercatabolic state.Nutritional support for patients with SAP is needed.EN by the jejunal route does not stimulate pancreatic secretions and is safe.At present,the beneficeal effects of EN towards improving the nutritional condition,protecting gut barrier function,reducing translocation of bacteria and endotoxins,modulating the inflammatory response,and decreasing the cost have been observed.Therefore,the EN rather than PN should be used by the jejunal route to provide nutritional support for patients with SAP.

Pruritus is the main symptom ofdermatosis.This article analyzes the dermatic pruritus induced by wind pathogen, and introduces the determination oftreatment for dermatic pruritus based on syndrome differentiation with eliminating wind

【Objective】In-vitro antibacterial activity of the combination of Herba Violae(HV)and Herba Taraxaci(HT)in different proportions was compared and analyzed for the optimization of the combination proportion of Herba Violae and Herba Taraxaci and the influencing factors.【Methods】The minimum inhibitory concentration(MIC)of the combination of HV and HT was determined by agar double dilution method and the minimum bactericidal concentration(MBC)by broth dilution method,and bactericidal curve was traced.Meanwhile,the resistance of the combination of HV and HT induced by sub-inhibitory concentration was analyzed,and the influencing factors of in-vitro antibacterial activity were investigated.【Results】The combination of HV and HT in the proportion of 1∶4 had a better antibacterial activity on four kinds of gram-positive bacteria and on four kinds of gramnegative bacteria,and exerted an bactericidal effect on Escherichia coli and Klebsiella Pneumoniae(both MBC_(50)/MIC_(50) and MBC_(90)/MIC_(90) being 2).The bactericidal curve showed that 2?Log cfu/mL bacteria strain could be killed by the combination of the proportion being 1∶4 at 8~(th) hour,the effect being superior to that of other two combinations.Inoculation dosage,serum amount and pH value had no effect on in-vitro antibacterial activity.【Conclusion】The combination of HV and HT in the proportion of 1∶4 has a better antibacterial activity.

Objective To investigate the clinical values of preoperative through-the-scope(TST) stent implementation by analyzing its effectiveness and reliability in patients with acute colonic obstruction caused by proximal colonic cancer.Methods From June 2008 to June 2014,36 patients with proximal colonic cancer accompanied by acute obstruction were analyzed.Obstructive sites consisted of ileocecal junction(n =4),ascending colon(n =20),and transverse colon near the hepatic flexure(n =12).A-chievement ratio of the colonic tumor resection,the incidence rate of complications,operation time,and hospitalization were evaluated.Results TTS was successfully placed in all patients.All patients showed relief of obstructive symptoms within 1 ~2 days.Surgical resection was performed after 5 ~7 days.A total of 34 patients got a radical colonic tumor resection,while the other two patients had liver and pelvic metas-tasis.All patients were welly recovered without complications of anastomotic leakage,intraperitoneal infec-tion and bleeding.Conclusion For patients with acute colonic obstruction caused by proximal colonic cancer,preoperative through-the-scope(TST)stent implementation is a cost-effective and safe method.It reduces trauma and pain,and enhances life quality for patients,which is worthy of being spread.

OBJECTIVE:To discuss the development of the core competitive power of domestic vitamin C manufacturing enterprises.METHODS:To analyse the characteristic of vitamin C industry in China and the competitive situation in the new market enviroment after China entry into WTO and to study the value chain of Chinese enterprises.RESULTS&CONCLU?SION:In order to develop the new core competitive power,it is important to breed the core of value chain that is based on in?novation.

Alveolar echinococcosis (AE) is a potentially fatal zoonosis caused by Echinococcus multilocularis (E .m) , primary located in the liver and showed malignant invasion .AE can develop to the lungs and brain metastases .Operation treat-ment and medication therapeutic efficacy show poor effect .The mechanism of AE invasive growth and metastasis is unclear . Angiogenesis is a highly regulated behavior in normal tissues .Abnormal angiogenesis is one of the key signs of malignant tumor ,and VEGF is one of the key mediators of angiogenesis .Numerous studies have shown that VEGF and CD34 plays an important role in the formation of tumor angiogenesis and invasive growth process .This article discussed the role of angiogene-sis in AE aggressive ,aimed to provide a new way for the clinic conservative treatment for patients with advanced stage ,preven-ting recurrence after operation ,and adjunctive therapy of operation and drug .
