Objective To introduce the techniques and specification of complete-block radical gastrectomy, and to compare with traditional radical gastrectomy in the operative time, surgical costs and postoperative complications. Methods Thirty gastric cancer patients meet the criteria were randomly divided into 2 groups. Group A: complete-block radical gastrectomy;group B: radical gastrectomy. Analysis and comparison were made on tumor site, time consuming of block, the proportion of gastrointestinal reconstruction, operative time, cost of block, pathological TNM stage, length of stay, postoperative complications and postoperative chemotherapy. Results Group A has longer operative time than group B (P<0.05). However, there was no significant statistical difference in the other indicators between these 2 groups. Conclusions Complete-block technology can separate cancer more completely during operation with the advantage of simplicity, low-cost, little effect on the subsequent operation. The incidence of postoperative complications and length of stay with the traditional surgery there was no significant difference.

· AlM: To study the effect of bone mesenchymal stem cells ( BMSCs ) and chondroitinaseABC ( ChABC ) on photoreceptor apoptosis in the retina of sodium iodate-induced rats.
·METHODS:Forty Sprague Dawley rats ( SD rats) were intraperitoneally injected with NalO3 (30g/L, 100mg/kg) to establish the retinal degeneration models ( postnatal 28d).These rats were devided into 4 groups.Group A was not injected, group B was injected with BMSCs, group C was injected with BMSCs and ChABC, and group D was injected with phosphate buffer saline ( PBS).After 28d, subretinal injection were applied. Hematoxyln - eosinstaining ( HE ) , tunel and immunohistochemistry were performed at 21d after subretinal injection.
· RESULTS: Photoreceptor number and photoreceptor apoptosis rate of B and C groups were more than those of A and D groups, and there was significant difference statistically ( P <0.05 ) . Photoreceptor number and photoreceptor apoptosis rate of group B were compared with those of group C, and there was no statistical significance between B and C groups ( P>0.05 ) .Glial fibrillary acidic protein ( GFAP) was expressed by BMSCs after intraocular injection.
· CONCLUSlON: BMSCs and ChABC injected into subretinal space may alleviate photoreceptor apoptosis so as to protect retinal photoreceptor cells in degenerated rats.

AIM:To investigate the value of pattern visual evoked potential (PVEP) and flash electroretinogram (FERG) in early diagnosis and prevention of diabetic retinopathy (DR), analyzing the correlation of early stage DR with PVEP and FERG.
METHODS: Sixty patients, 30 males and 30 females, participated in observation group. Their average age was 19. 42 ± 7. 78years. The duration of DM was < 5a. Best corrected visual acuity was 5. 0. Fasting blood glucose was 7. 8± 3. 6mmol/ L. There were 60 subjects, 30 males and 30 females, in control group. Their average age was 17. 2 ± 6. 52years. Best corrected visual acuity was 5. 0. Every participator was tested with PVEP and FERG according to ISCVE standard. The amplitude of PVEP and P100 latency were recorded. And the b-wave latency, b-wave amplitude, a - wave latency, a - wave amplitude were showed down.
RESULTS: In observation group, P100 amplitude decreased and P100 latency increased, compared to those of control group ( P< 0. 01); b - wave latency, b -wave amplitude, a - wave latency, a - wave amplitude were different from those in control group(P<0. 01); the fasting blood glucose kept stable; P100 amplitude, b -wave amplitude and a-wave amplitude were not related to the DM duration; P100 latency, a-wave latency and b-wave latency were related to the DM duration.
CONCLUSION: PVEP are sensitive to optic neuron damage; FERG is desirable to detect the lesion of Müller cells and bipolar cells. P100 amplitude by PVEP, b-wave amplitude by FERG may be the most sensitive parameter for DR at early stage.

Objective To study prevalence of metabolic syndrome (MS) , it's components and hyperuricemia (HUA) among Kazakh people in Xinjiang Uighur autonomous region, China. Methods A cross-sectional survey was conducted among Kazakh people aged 35 years and over in seven prefectures of Xinjiang, including Urumqi, Kelamayi (Karamay) , Fukang, Tulufan (Turpan), Hetian (Hotan) , Aletai (Altay) and Yili during October 2007 to March 2010, with a four-stage cluster sampling, the total sample size were 4094. Through the methods of questionnaire survey, physical examination, biochemical examination and so on, to study prevalence of MS in HUA and it's components by blood biochemical examinations. Results A total of 3915 Kazakh adult people, equal number of men and women, were surveyed, with a response rate of 95. 63 percent. Overall prevalence of HUA was 3. 96 percent( 155/3915 ) , 6.02 percent for men and 2. 03 percent for women(114/1894 and 41/2021) , respectively, with statistically significant difference ( P < 0.05 ). Prevalence of MS was 39.47 percent in those with HUA and 22. 53 percent in those without HUA (45/114 and 401/1780), respectively (P < 0.01). Among women, prevalence of MS was 46. 34 percent in those with HUA and 16. 11 percent in those without HUA( 19/41 and 319/1980), respectively (P<0. 01). Prevalence of high blood pressure, hypertriglyceridemia, lower blood high-density lipoprotein cholesterol (HDL-C) and central obesity were 59.65 percent, 42.11 percent,32.46 percent, 7. 89 percent and 79. 82 percent in those with HUA, respectively, with prevalence of hyperglyceridemia and central obesity significantly higher than in those of non-HUA ( P < 0. 05 ). Among women, prevalence high blood pressure, hypertriglyceridemia, lower blood HDL-C and central obesity were 48.78 percent, 39.02 percent, 41.46 percent, 2.44 percent and 78.05 percent, respectively, in HUA group, with prevalence of hyperglyceridemia, lower blood HDL-cholesterol and central obesity significantly higher than in those of non-HUA ( P < 0. 05 ). Conclusions Prevalence of MS was higher in Kazakh people suffered with HUA than those without HUA, as well as prevalence of components of MS, suggesting that prevention and treatment for HUA is necessary, which can reduce MS and its components in the region.

In this study, we explored the mechanism of Huganning tablet (HGNP) in the treatment of nonalcoholic fatty liver disease (NAFLD) based on network pharmacology and computer-aided drug design. Firstly, the potential ingredients and targets of HGNP were identified from TCMSP database, Swiss Target Prediction database, Chinese pharmacopoeia (2015) and literatures, and then the targets of HGNP intersected with NAFLD disease targets that obtained in GeneCards database to acquired potential targets. The bioconductor bioinformatics package of R software was used for gene ontology (GO) enrichment and Kyoto encyclopedia of genes and genomes (KEGG) enrichment analysis. The network of “potential ingredient-key target-pathway” was formed in Cytoscape software to study the interactions between potential ingredients of HGNP, key targets, pathways and NAFLD. Based on the results of network pharmacology, the molecular docking analysis of the key targets and potential active ingredients in HGNP tablets with top degree in the network was conducted using Discovery Studio 2020 software, followed by molecular dynamics simulations, binding free energy calculation, drug-likeness properties analysis and ADMET (absorption, distribution, metabolism, excretion and toxicity) properties prediction.
