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.

AIM:To develop a method for determining cholic acid by HPLC-ELSD and GC was applied to determing muscone;in Jawei Xihuang Soft Capsule(Calculus Bovis,Moschus,Venenum Bufonis,Olibanum,Myrrha).METHODS:A C18 column(Kromasil C18,5 ?m,4.6 mm?250 mm)was used as stationary phase,the mobile phase was methanol-0.01% glacial acetic acid(73:27) at a flow rate of 1.0 mL/min.The parameters of ELSD were set as follows:evaporation temperature was 40 ℃,carrier gas(N2) pressure was 200 kPa.The GC system consisted of DB-1 capillary column(30 m?0.32 mm?0.25 ?m) and FID as the detector.The programmed temperature-GC and internal standard method were employed to determine the content of muscone.RESULTS:The linear ranges of cholic acid and muscone were in the range of 45.2 ng-904 ng and 0.05 mg/mL—0.5 mg/mL respectively.The average recoveries were 99.06% and 99.40% with RSD of 1.56% and 0.95% respectively.CONCLUSION:The method is convenient and accurate,and it can be used for the quality evaluation of Jawei Xihuang Soft Capsule.

· 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 investigate prevalence and risk factors of peripheral artery disease (PAD), metabolic syndrome (MS) and peripheral artery disease complicated with metabolic syndrome among Kazakh adults lived in Xinjiang Yili prefecture. Methods Four-stage cluster sampling method was used to select adults aged 35 years and over for the study from six cities and prefectures of Xinjiang. All the participants were interviewed with questionnaire to collect their demographic characteristics. Physical checksup and blood biochemical measurements were performed for all of them, as well as blood pressure was measured in their lower legs and arms to calculate ankle brachial pressure index ( ABPI), a ratio of the blood pressure in the lower legs to that in the arms. Only data of Kazakh adults in Yili prefecture were analyzed in this paper, including prevalence and risk factors for PAD and MS, as well as their relationship.The patients with PAD were divided into two groups, one complicated with MS and the other without it Logistic regression analysis was used to identify potential risk factors for PAD and MS and their combination.Results A total of 1365 adult Kazakh people were surveyed. Prevalence of MS was 23.7 percent, 30.4 percent for men and 19.0 percent for women, respectively, and that of PAD was 9. 4 percent, 7.0 percent for men and 11.0 percent for women, respectively. Mean age in patients of PAD complicated with MS was older than that in those without MS (t=-5.348, P＜0.01). Risk of PAD complicated with MS in Kazakh people associated with gender ( men), age, systolic pressure, diastolic pressure and blood glucose level.(P＜0.05). Conclusions Both prevalence of PAD and MS are significantly higher among Kazakh people in Yili prefecture of Xinjiang, and increase with age. Prevalence of PAD is significantly higher in those with MS than that in those without MS. Risk factors of PAD complicated with MS include gender(men), age,systolic pressure, diastolic pressure and blood glucose level.

Objective To investigate the association between matrix metalloproteinase-9 (MMP-9) gene polymorphism (-1562C ＞ T/R279Q) and acute coronary syndrome (ACS) in Uygur nationality of Xinjiang Autonomous Region of China. Methods A total of 352 patients with ACS including 213 patients with unstable angina pectoris and 139 patients with acute myocardial infarction evidenced by using coronary arteriography and 421 control subjects were recruited in this study. The MMP-9-1562C ＞ T and R279Q genotypes were detemined by using PCR-RFLP method. The relationship between the polymorphism in the MMP-9 gene and the severity of coronary arterial stenosis was analyzed. All polymorphisms were determined for confimation with Hardy-Weinberg expectations in both groups separately. Differences in distributions of genotypes and alleles between two groups were analyzed with x2 test. The association between the MMP-9 polymorphisms and the risk of ACS was estimated by odds ratio(Ors) and their 95% confidence intervals (CIs), and the comprehensive evaluation of the factors associated with ACS was determined by using multifactor logistic regression. P ＜ 0. 05 was considered to be statistically significant. Results The genotype frequencies for CT + TT genotypes and T allele were 25.9 and14.5 percent in ACS subjects and 15.7 and 8.4 percent in control subjects, respectively. The genotype frequencies were different significantly between the two groups (x2 = 12.26,P ＜ 0.01;x2 = 14.15,P ＜ 0.01, respectively). No relationship between R279Q polymorphism and ACS was found in this study ( P ＞ 0.05). The multifactor logistic regression analysis showed that the T allele carrier (CT + TT) significantly increased the risk of ACS compared with the CC genotype ( OR = 1.791,95 % CI: 1. 088 - 2.951, P = 0.022) after adjustment for tradition risk factors. The frequencies for CT + TT and CC genotypes of the -1562C ＞ T polymorphism were not statistically different among ACS patients with one, two and three or more significantly diseased vessels ( x2 = 1.15, P = 0.56). Conclusions The findings suggest that the polymorphism in MMP-9 gene promoter (-1562C ＞ T) is associated with the susceptibility to the ACS. The T allele might be an independent risk factor for the ACS. But the -1562C ＞ T polymorphism may not be useful as a predictor of the severity of coronary arterial stenosis. The R279Q polymorphism of MMP-9 gene was not significantly associated with ACS in this studied population.
