OBJECTIVETo study the effect of total flavanones of Sedum sarmentosum (SSTF) on the apoptosis of rat hepatic stellate cells (HSC-T6) and its mechanism.

METHODDifferent concentrations of SSTF and HSC-T6 cells were co-cultured for different period of time. The MTT assay was used to detect the inhibitory effect of SSTF on the proliferation of HSC-T6 cells. The flow cytometry Annexin-V/PI double staining method was adopted to detect SSTF's effect on HSC-T6 cell apoptosis. Western blotting and Real-time PCR methods were applied to observe the effect on the protein and mRNA expressions of apoptosis-related cytokines Bcl-2, Bax and Caspase-3.

RESULTSSTF significantly inhibited HSC-T6 cell proliferation and induced cell apoptosis in a dose and time dependent manner. According to Western blotting result, SSTF promoted apoptosis by inhibiting Bcl-2, Bax and promoting the protein expression of Caspase-3; according to a further Real-time PCR study, Bcl-2 mRNA levels can inhibit Bcl-2 and promote Bax and Caspase-3 expressions.

CONCLUSIONSSTF has the effect of promoting the apoptosis of HSC-T6 mainly by inhibiting Bcl-2 and promoting protein and mRNA expressions of Bax and caspase-3.

AlM:To compare the efficacy and safety of latanoprost and brimonidine in the treatment of open angle glaucoma, and provide reference for rational drug use.METHODS:A total of 121 cases ( 136 eyes ) who were diagnosed as primary open angle glaucoma were selected in this study, and they were randomly divided into experimental group (62 cases, 70 eyes) and control group ( 59 cases, 66 eyes) according to different drug treatment. Patients in the control group received brimonidine eye drops twice a day, while patients in the experimental group received latanoprost eye drops once a day. The intraocular pressure, visual acuity and adverse reactions were checked of the two groups in the following 3mo.RESULTS:The intraocular pressure of patients in the control group was 18. 1 ± 1. 3mmHg, while the experimental group was 17. 0 ± 0. 9mmHg after 12wk of treatment, which were both lower than before (P<0. 05). The fluctuation of intraocular pressure in the experimental group was significantly lower than that of the control group. There was no significant difference in the LogMAR visual acuity between before and after treatment in the control group, while the LogMAR visual acuity of the experimental group was significantly improved. The control group had hyperemia, burning sensation, tearing, eyelid edema and other adverse side effects, and the experimental group had little adverse reactions. CONCLUSlON: Latanoprost can significantly reduce intraocular pressure in glaucoma patients with in the follow- up time, and reduce the impact of elevated intraocular pressure in the vision of glaucoma patients, with little adverse reaction, worthy of clinical application.

OBJECTIVETo study the clinical effect of "Jin's three-needling" in the treatment of generalized anxiety disorder.

METHODSFifty-eight patients with generalized anxiety were randomly assigned to two groups equally, the medication group treated with anti-anxiety drugs and the acupuncture group with "Jin's three-needling". The treatment course was 6 weeks. The clinical effects were evaluated with Hamilton anxiety scale (HAMA), clinical global impression (CGI), and treatment emergent symptom scale (TESS) before treatment and at the end of 2nd, 4th, 6th week of the treatment course. The concentration of 5-hydroxytryptamine (5-HT) in platelet, and plasma levels of corticosterone (CS) and adrenocorticotropic hormone (ACTH) were measured with high performance liquid chromatography-electrochemical detection (HPLC-ED) method before and after treatment.

RESULTSThe clinical effects in the two groups were equivalent, while the adverse reaction found in the acupuncture group was less than that in the medication group (P < 0.05). The platelet concentration of 5-HT and plasma ACTH level decreased significantly in both groups after treatment with insignificant difference between the group (P < 0.05). The plasma CS level had no obvious change in the two groups after treatment as compared with that before treatment respectively.

CONCLUSION"Jin's three-needling" shows similar curative effect on generalized anxiety to routine Western medicine but with less adverse reaction, which may be realized through regulating the platelet 5-HT concentration and plasma ACTH level.

Helicobacter pylori(Hp)is considered to be closely associated with gastritis,peptic ulcer,gastric cancer and other gastrointestinal diseases,but the detail of the pathogenesis is still unclear.The past researches often fo-cused on virulence factors such as CagA(cytotoxin-associated gene/protein A),VacA(vacuolating cytotoxin A), Urease and DupA(duodenal ulcer-promoting gene/protein A),but these are not enough to demonstrate the patho-genic mechanism.Recent studies have not only revealed some new progresses of these past virulence factors but also found that Hp flagllum,adhesion protein and hemolysin play important roles in the pathogenic mechanism.

Objective To investigate the susceptibility of amphotericin B,itroconazol and voriconazole against filamentous fungi.Methods Etest was used to determine the MIC of amphotericin B, itroconazol and voriconazole against filamentous fungi including Aspergillus,Penicillium,Alternaria alternate,Mucor and Rhizopus species.Results The average MIC of voriconazol,amphotericin B and itroconazol against Aspergillus fumiagtus is O.29 ?g/ml,1.16 ?g/ml and 5.88 ?g/ml;the average MIC of amphotericin B and voriconazol to Aspergillus flavus is 6.39 ?g/ml and 0.22 ?g/ml;the average MIC of voriconazol,amphotericin B and itroconazol against Aspergillus niger is 0.69,2.31,and 19.75 ?g/ ml.Most of Penicillium are susceptable to amphotericin B,but 3 strains showed very high MIC to voriconazol and itroconazol.Both of the testing strains of Mucor and Rhizopus were resistant to all of the three antifungal agents.Conclusion Amphotericin B,itroconazol and voriconazole possessed different susceptibility on different types of filamentous fungi.It is important for clinical laboratories to identify the filamentous fungi to the level of genus and species to help physicians choose antifungal agents correctly.

OBJECTIVETo study the clinical efficacy and adverse reaction of comprehensive therapy mainly with Chinese anti-cancer medicinal perfusion/embolization and assisted with Chinese drug-therapy based on TCM Syndrome Differentiation in treating primary liver cancer.

METHODSForty-one patients with liver cancer were divided into the treated group and the control group. To the treated group turmeric oil microballoon, cinobufotalin, Aidi injection and iodized oil were given via hepatic artery perfusion/embolization, and to the control group chemotherapeutic agents and iodized oil were given for instead. Besides, both groups were given Chinese herbs according to TCM Syndrome Differentiation additionally.

RESULTSThe tumor inhibitory rate in the treated group and the control group was 77.78% and 69.57% respectively, with insignificant difference between them. The improvement of fatigue and anorexia in the treated group was better than that in the control group (P < 0. 05). The 6-month, 12-month and 24-month survival rate in the treated group and control group was 61.11% vs 56.62%, 27.78% vs 30.43% and 22.22% vs 26.09%, respectively, the difference between the two groups was insignificant. The occurrence of adverse reactions such as decreasing of white blood cells, platelet and hemoglobin, nausea and vomiting were obviously lower in the treated group than those in the control group (P < 0.05).

CONCLUSIONChinese anti-cancer medicinal perfusion/embolization has affirmative short-term clinical effect in treating primary liver cancer with few adverse reactions, which was tolerable to patients, but its long-term clinical efficacy needs further observation.

BACKGROUNDPrevious studies suggested that zinc level was related to a certain diabetic microvascular complication. However, the relationship between zinc level and all the microvascular complications in type 2 diabetic patients remains unknown. The purpose of this study was to analyze the relationship between zinc level and each diabetic microvascular complication and identify the features related to low serum zinc level.

METHODSWe included the hospitalized patients with type 2 diabetes (T2D) at our department from May 30, 2013 to March 31, 2014. We initially compared the serum zinc levels between patients with specific microvascular complications and those without. We then analyzed the association between zinc level and each microvascular complication. Furthermore, we identified the unique features of patients with high and low serum zinc levels and analyzed the risk factors related to low zinc level.

RESULTSThe 412 patients included 271 with microvascular complications and 141 without any microvascular complications. Serum zinc level was significantly lower in patients with diabetic retinopathy (P < 0.001), diabetic nephropathy (DN, P < 0.001), or diabetic peripheral neuropathy (P = 0.002) compared with patients without that specific complication. Lower zinc level was an independent risk factor for DN (odds ratio = 0.869, 95% confidence interval = 0.765-0.987, P < 0.05). The subjects with lower serum zinc level had manifested a longer duration of diabetes, higher level of hemoglobin A1c, higher prevalence of hypertension and microvascular complications, and lower fasting and 2-h C-peptide levels.

CONCLUSIONSLower serum zinc level in T2D patients was related to higher prevalence of diabetic microvascular complications, and represented as an independent risk factor for DN. Patients with lower zinc level were more likely to have a longer duration of diabetes, poorer glucose control, and worse β-cell function.
