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.

The effect of adrenomedullin (AM) on insulin sensitivity in normal Wistar rats was investigated by hyperinsulinemic-euglycemic clamp in combination with isotope dilution technique. The infusion rates of AM during the clamp were 0, 0.05, 0.2, 1 ?g?kg~(-1)?min~(-1), rspectively. The glucose disposal rate (GDR) and hepatic glucose output (HGO) were calculated by the plasma 3-~(3)H-glucose specific activity. After AM infusion, the insulin-mediated glucose disposal was reduced in a dose-dependant manner. It indicated that high dose of AM could induce a marked state of insulin resistance, which was mainly characterized by inhibition of the effect of insulin to stimulate peripheral glucose metabolism.

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 .

More and more studies indicate that type 2 diabetes mellitus (T2DM) is an independent risk factor of the cognitive impairment. It is showed that factors such as diabetic vascular complications and inherenrt metabolism impairment, affect the cognitive functions of the diabetics, and poorly controlled blood sugar and insulin resistant may also play a role in it.

Objective To discuss the effect of modified venipuncture method on success rate of vcnipuncture, in order to alleviate the suffering of patients with emergency transfusion. Methods 380 cases of transfusion patients were randomly divided into the routine group and the modified group, rou-tine and modified venipuncture methods were applied to each group respectively. The success rate and pain response of each group were compared between the two groups by χ2 test. Results The success rate of venipuncture of the modified group was 93.50%, which was significantly higher than that of the routine group, and the rate of pain of the modified group was lighter than that of the routine group. Conclusions The modified venipuncture method can alleviate pain of patients, improve work efficien-cy and was worthy of clinical nursing application.

Schwann cells are the seed cells of tissue engineedng in the regeneration of peripheral nerve.so whether we can harvest enough Schwann cells of high purity is very important in the tissue engineering.Culture and purification technology of Schwann cells has been improved day by day.The classical cultural methods include tissue-clump cultural method and enzyme digestion cultural method.On the basis of the classical cultural methods,someone uses new technologies to delete fibroblasts,such as addition of cytosine arabinoside,addition of antimitogenic agents.The latest purified methods include magnetic activated-cells separation,co-culture with three-dimensional scaffolds and laminin-coated wells purified method.The aim of the skills above is to provide enough Schwann cells for the tissue engineering repeir of degenerated peripheral nerves.There are many ways of Schwann cells culture and purification.and we have made a primary progress,but it still needs further studies before the entire achievemenL such as long cycle,low activity in cultured calls,and the instable biological characteristics during passage culture,etc.

Objective To explore the expression and significance of TGF-β1 and CTGF in the occurrence and development of patients with subarachnoid hemorrhage. Methods Cerebrospinal fluid TGF-β1 and CTGF concentrations in all subjects were serially detected by ELISA. Results Mean total TGF-β1 and CTGF in patients were elevated more than that in controls at the first day(P＜0.05).Thereafter the levels of TGF-β1 and CTGF fell by the third day, then rose to the second peak at the tenth day and remained significantly increase until the sixteenth day(P＜0.05).The levels of TGF-β1 was positive correlated CTGF. Conclusion The expressions of TGF-β1 and CTGF in patients with subarachnoid hemorrhage showed two peaks character. After SAH, the concentration of TGF-β1 and CTGF concentration is related to chronic communicating hydrocephalus.
