AIM:To investigate the clinical effect of panretinal photocoagulation (PRP) combined with calcium dobesilate in treatment of diabetic retinopathy (DR).METHODS:Selected 120 cases (240 eyes) of DR diagnosed in our hospital from January 2011 to January 2016 were retrospectively analyzed.According to whether calcium dobesilate was used, the treatment group was divided into two groups.Sixty cases were treated with PRP combined with calcium dobesilate, and 60 cases in the control group were treated with PRP only.The BCVA, CMT and clinical efficacy of the two groups were compared.RESULTS:Before treatment, there was no significant difference on BCVA between combined group and control group (P>0.05).After treatment, BCVA of combined group was higher than that of the control group (P<0.01).Before the treatment, no statistically significant difference between combined group and control group on CMT, neovascularization and fluorescein leakage area were found (P>0.05);after treatment, the combination group on CMT, neovascularization and fluorescein leakage area value were less than the control group (P<0.01).After treatment, combined group was appearance effect in 65.0%, effective in 30.0%, invalid in 5.0%, the control group was 50.8%, effective 36.7%, invalid 12.5%, all statistically significant differences between the two groups (P<0.05).CONCLUSION:PRP combined with calcium dobesilate in treatment of DR has a more significant clinical effect than PRP alone.

In order to investigate the anti-leukemia effects of gambogic acid (GA) and its relation to the regulation of nucleoporin Nup88 in U937 cells in vitro, the inhibitory effect of GA on the growth of U937 cells was examined by using MTT assay. Apoptosis was detected by Annexin-V FITC/PI double-labeled cytometry. Cell cycle regulation was studied by propidium iodide method. Both flow cytometry (FCM) and RT-PCR were employed to assess the expression of Nup88, and the localization of Nup88 was determined by confocal microscopy. The results indicated that GA had strong inhibitory effect on cell proliferation and apoptosis induction activity in U937 cells in vitro in a time-and dose-dependent manner. The 24-h IC(50) value was (1.019+/-0.134) mg/L. Moreover, GA induced arrest of U937 cells in G(0)/G(1) phase. Over-expression of Nup88 was found in U937 cells, whereas GA could significantly down-regulate both the protein and mRNA levels of Nup88. Nup88 was diffusely distributed between nucleus and cytoplasm and was located at the cytoplasmic side of nuclear rim, and occasionally in cytoplasm. It is suggested that GA exerts its anti-leukemia effects by regulating the expression and distribution of nucleoporin Nup88. It promises to be new agent for the treatment of acute leukemia.

Objective To investigate the epidemiological characteristics and risk factors of clonorchiasis of hospital patients in Heilongjiang Province,so as to provide the evidence for formulating the control and prevention strategies. Methods A total of 2 359 suspected patients from human parasitic disease research institute of Harbin medical university were investigated. Total?ly 6 718 stool samples and 2 359 serum samples were tested by Kato?Katz technique and the enzyme linked immune method re?spectively. Meanwhile,the information of the patients was collected by questionnaires. Results Totally 513 suspected patients were infected with Clonorchis sinensis. The infection rate of the suspected patients was higher in the ≥29 group(P<0.05), and the infection rate and positive rate of blood tests of the rural suspected patients were both higher than those of the urban sus?pected patients(both P<0.05). The habit of eating raw fish and shrimp was the risk factor of clonorchiasis. Conclusion Clo?norchiasis is one of the main food?borne parasitic diseases in Heilongjiang Province. The habit of eating raw fish and shrimp is the risk factor of clonorchiasis.

Objective To quantitatively evaluate left ventricular layer-specific strain using speckle tracking imaging,and their relationship with age and gender in nornal subj ects.Methods GE Vivid E9 equipment with EchoPAC BT1 2 workstation were used.One hundred and nineteen healthy subj ects were enrolled in this study.Results Left ventricular global longitudinal and circumferential strain was highest in the endocardium and lowest in the epicardium.Longitudinal and circumferential 3-layer strain was highest in the apex and lowest in the base.Age and gender had little influence on the left ventricular layer-specific strain.Conclusions Speckle tracking imaging can quantitatively assess left ventricular layer-specific strain, providing another useful modality for evaluating cardiac function.

Objective To investigate the association of the polymorphism of the N-acetyltransferase 2 (NAT2 )gene with isoniazid-induced hepatotoxicity and anti-tuberculous treatment efficacy in Chinese Han patients with tuberculosis(TB).Methods A total of 108 TB patients who received initial anti-TB treatment were followed up prospectively.A polymerase chain reaction direct sequencing approach was used to detect genetic polymorphisms of the NAT2 gene.Associations between NAT2 genotype and isoniazid-induced hepatitis/early treatment were analyzed.Chi-square test was used for statistical analysis. Results Among the 108 TB patients, intermediate-acetylators (IA ) was the most frequent NAT2 genotype with the proportion of 54.63%(59/108).The proportion of rapid-acetylators(RA)was 33.33%(36/108),slow-acetylators (SA)was 10.19%(11/108)and super-rapid acetylators was 1 .85 % (2/108). Among the 20 patients who developed drug-induced hepatitis,2 were RA,5 were SA and 13 were IA. Regarding NAT2 genotype,RA patients had a lower incidence of hepatotoxicity (OR =0.176,95 %CI :0.038-0.809,P =0.014)and SA patients were more likely to developed drug-induced hepatic injury (OR=4.556,95 %CI :1 .231 -16.854,P =0.044 ).Statistical analysis revealed that the frequency of variant diplotypes,NAT2*4/*6A (OR=7.741 ,95 %CI :2.653-22.586,P <0.01 )and NAT2 *6A/*6A (OR=15 .353,95 %CI :1 .506 -156.552,P =0.020)were significantly increased in TB patients with hepatotoxicity.NAT2 *4/*4 was less likely to developed hepatic injury (OR =0.176,95 %CI :0.038-0.809,P =0.014).Among the 58 culture-positive patients,12(31 .03%)were persistent culture positive after 2 months standard therapy.Early treatment failure was observed with significantly higher incidence rate in RA than other genotypes (OR = 7.200, 95 % CI :1 .794-28.900, P = 0.008). Conclusions In Chinese Han TB patients,IA is the most frequent NAT2 genotype.The SA status of NAT2 is a risk factor of isoniazid-induced hepatotoxicity.The diplotype of NAT2 *6A has clearly high risk of isoniazid-induced hepatotoxicity.In contrast,NAT2 * 4/* 4 is protective diplotype.RA is associated with early treatment failure in culture-positive patients.

LC-Q-TOF-MS and LC-IT-MS in positive and negative ion mode were applied to simultaneously characterize the constituents in Suanzaoren tang. Analysis was performed on an Agilent Zorbax SB-C18, Rapid Resolution HT column(4.6 mmx 50 mm, 1. 8 micro m) with gradient elution of acetonitrile(A) -aqueous solution containing 0. 05% formic acid(B) at a flow rate of 0. 6 mL min(-1) and the column temperature was 30 degreesC. By comparing MS fragmentation, accurate molecular weight, literature date and standard compounds information, a total of48 compounds were successfully identified or speculated. The origins of these compounds were assigned to the corresponding Chinese medicine. Thirty-one compounds were reported in Suanzaoren tang for the first time. LC-Q-TOF-MS combined with LC-IT-MS is a simple and rapid tool for the identification of constituents of Suanzaoren tang, and the results could provide evidence for the research on quality combined and effective constituents of Suanzaoren tang.
