Objective To investigate the clinical efficacy of therapy of clearing heat,percolating dampness and lowering turbidity combined with Silibin Meglumine Tablets in the treatment of non-alcoholic steatohepatitis(NASH)patients with abnormal alanine aminotransferase(ALT)level of damp-heat accumulation type.Methods A retrospective study was conducted.According to the medication,80 patients with NASH with abnormal ALT level of damp-heat accumulation type were divided into control group and observation group,with 40 cases in each group.The control group was treated with Silibin Meglumine Tablets,and the observation group was treated with therapy of clearing heat,percolating dampness and lowering turbidity on the basis of treatment for the control group.The course of treatment covered 12 weeks.The changes of liver function indicators of ALT,aspartate aminotransferase(AST),and gamma glutamyl transpeptidase(GGT),blood lipid indicators of total cholesterol(CHOL)and triglyceride(TRIG),and the degree of hepatic steatosis in the two groups were observed before and after treatment.After treatment,the clinical efficacy and safety of the two groups were evaluated.Results(1)After 12 weeks of treatment,the total effective rate of the observation group was 95.00%(38/40),and that of the control group was 77.50%(31/40).The curative effect of the observation group was significantly superior to that of the control group,and the difference was statistically significant(P＜0.05).(2)After treatment,the levels of ALT,AST and GGT in the two groups were significantly lower than those before treatment(P＜0.05),and the decrease of ALT,AST and GGT in the observation group was significantly superior to that in the control group(P＜0.05).(3)After treatment,the levels of CHOL and TRIG in the two groups were significantly lower than those before treatment(P＜0.05),and the decrease of CHOL and TRIG in the observation group was significantly superior to that in the control group(P＜0.05).(4)After treatment,the degree of hepatic steatosis in the two groups was significantly lower than that before treatment(P＜0.05),and the decrease of the degree of hepatic steatosis in the observation group was significantly superior to that in the control group(P＜0.05).(5)During the treatment,no obvious adverse reactions occurred in the two groups,indicating high safety.Conclusion The therapy of clearing heat,percolating dampness and lowering turbidity combined with Silibin Meglumine Tablets exerts certain effect in the treatment of NASH patients with abnormal ALT level of damp-heat accumulation type,and the therapy can significantly enhance the clinical efficacy of Silibin Meglumine Tablets alone for NASH.

OBJECTIVE: To develop a convenient method for rapid purification of fresh Pheretima proteins and assess the inhibitory effect of these proteins against pulmonary fibrosis. METHODS: The crude extract of fresh Pheretima was obtained by freeze-drying method and then purified by size exclusion chromatography. The composition of the purified proteins was analyzed by mass spectrometry. MRC-5 cells were treated with 5 ng/mL TGF-β1 alone (model group) or in combination with SB431542 (2 μmol/L) or the purified proteins (13.125 μg/mL), and the cytotoxicity of purified proteins and their inhibitory effects on cell proliferation were detected with CCK8 assay. Flow cytometry was used to detect the changes in cell apoptosis, and the cellular expressions of α-SMA, Vimentin, E-cadherin, collagen I, Smad2/3 and P-Smad2/3 were detected using RT-PCR and Western blotting. In the animal experiment, adult male C57BL/6 mice were subjected to intratracheal instillation of bleomycin followed by treatment with the purified proteins (5 mg/mL) for 21 days, after which HE and Masson staining was used to observe the pathological changes in the lung tissue of the mice. RESULTS: We successfully obtained purified proteins from fresh Pheretima protein by size exclusion chromatography. Treatment with the purified proteins significantly inhibited TGF-β1-induced proliferation of MRC-5 cells (P < 0.01), reduced the cellular expressions of α-SMA, Vimentin and collagen I (P < 0.001 or P < 0.01), increased the expression of E-cadherin (P < 0.01), and inhibited the expressions of Smad2/3 and P-Smad2/3 (P < 0.001 or P < 0.01). In male C57BL/6 mice models of bleomycin-induced pulmonary fibrosis, treatment with the purified proteins obviously reduced the number of inflammatory cells and fibrotic area in the lungs. CONCLUSION The purified proteins from fresh Pheretima obtained by size exclusion chromatography can inhibit pulmonary fibrosis in mice by regulating the TGF-β/ Smad pathway.

OBJECTIVE: To identify the key outcome indexes in treatment of migraine with acupuncture and moxibustion. METHODS: Using literature research, questionnaire survey and consensus conference, the key outcome indexes in treatment of migraine with acupuncture and moxibustion were screened and prioritized. RESULTS: The critical outcome indexes for the treatment in attack stage of migraine included 6 effectiveness outcome indexes (headache intensity, headache duration, headache relieve time, effectiveness and level of headache relief within 2 h, headache-related quality of life, level of headache relief within 24 h) and 1 safety outcome index (incidence of serious adverse reactions). The critical outcome indexes for prophylactic treatment included 6 effectiveness outcome indexes (headache day, headache frequency, headache intensity, effective rate, headache-related quality of life, health-related quality of life) and 1 safety outcome index (incidence of serious adverse reactions). CONCLUSION In terms of the attack stage treatment and prophylactic treatment with acupuncture and moxibustion, the outcome indexes are different, among which, those can directly reflect the conditions of migraine should be optioned in priority. To assess the effectiveness of attack stage, the headache intensity is preferred, using the visual analogue scale (VAS) score, and the preferred time is 2 hours after treatment. Regarding the effectiveness of prophylactic treatment, the headache day, headache frequency and headache intensity should be firstly considered in the assessment, in which, the preferred time for assessment is 12 weeks into treatment, while, the best time for follow-up should be 12 weeks after treatment completion. When the quality of life is considered, the migraine-specific quality of life questionnaire (MSQ) is the top option. For either the attack stage treatment or the prophylactic treatment, the high attention should be laid on the outcome indexes for safety and medical economics evaluation.

Objective To explore the effect of S100 calcium ion binding protein A6 (S100A6) on proliferation and migration of esophageal adenocarcinoma SK-GT-4 cells. Methods Lenti viruses were used to construct stable transfected cell lines (shNC and shS100A6). Real-time PCR was used to detect the mRNA expression of S100A6. The inverted microscope and MTT were used to detect cell proliferation. The Transwell assay was used to detect cell migration. Western blotting was used to detect the expression of S100A6, p-ERK, p-Akt and its downstream molecular involved in proliferation and migration. Using U0126 ( inhibitor of MER1/2) and LY294002 ( inhibitor of PI3K) to detect the effect of these two inhibitors on cell proliferation and migration and the expression of p-ERK, p-Akt and its downstream molecular involved in proliferation and migration in shS100A6 cells. Results Stable cell lines of knockdown S100A6 were constructed. Knockdown S100A6 promoted cell proliferation and migration. Western blotting result displayed that in shS100A6 cells, the levels of p-Akt and p-ERK increased, p21 decreased, cyclinDl increased, and the expression of β-catenin and vimentin, increased. U0126 and LY294002 inhibited the migration of shS100A6 cells. U0126 had no effect on the proliferation of shS100A6 cells, however LY294002 could inhibit the proliferation of shS100A6 cells. U0126 treatment on shS100A6 cells could decrease p-ERK and β-catenin expression. After shS100A6 cells treated with LY294002, p-Akt and β-catenin expression decreased, p21 expression increased and the expression of cyclinDl decreased. Conclusion Low expression of S100A6 promotes cell proliferation and migration, which may be mediated by activation of p-Akt regulating cell cycle progression to promote cell proliferation and by activation of p-Akt/p-ERK to regulate β-catenin to promote cell migration.

OBJECTIVES: To study the changes of alcohol content and pharmacokinetic parameter in rats after taking Huoxiang Zhengqi liquid. METHODS: The rats were randomly divided into three groups and given with white alcohol at the dose of 3.0 mL/kg, low-dose and high-dose Chinese medicine liquor, respectively. The blood was collected before administration and 5 min, 10 min, 15 min, 30 min, 1 h, 2 h, 3 h, 4 h, 5 h, 6 h and 8 h after administration by cutting rats' tails.

Traumatic gas gangrene is a fatal infection mainly caused by Clostridium perfringens. It is a challenge to manage gas gangrene in open wounds and control infection after debridement or amputation. The aim of the present study was to use vacuum sealing drainage (VSD) with continuous irrigation of potassium permanganate to manage infective wounds of gas gangrene and observe its clinical efficacy. A total of 48 patients with open traumatic gas gangrene infection were included in this study. Amputations were done for 27 patients, and limb salvage procedures were performed for the others. After amputation or aggressive debridement, the VSD system, including polyvinyl alcohol (PVA) foam dressing and polyurethane (PU) film, with continuous irrigation of 1:5000 potassium permanganate solutions, was applied to the wounds. During the follow-up, all the patients healed without recurrence within 8-18 months. There were four complications. Cardiac arrest during amputation surgery occurred in one patient who suffered from severe septic shock. Emergent resuscitation was performed and the patient returned to stable condition. One patient suffered from mixed infection of Staphylococcal aureus, and a second-stage debridement was performed. One patient suffered from severe pain of the limb after the debridement. Exploratory operation was done and the possible reason was trauma of a local peripheral nerve. Three cases of crush syndrome had dialysis treatment for concomitant renal failure. In conclusion, VSD can convert open wound to closed wound, and evacuate necrotic tissues. Furthermore, potassium permanganate solutions help eliminate anaerobic microenvironment and achieve good therapeutic effect on gas gangrene and mixed infection. VSD with continuous irrigation of potassium permanganate is a novel, simple and feasible alternative for severe traumatic open wounds with gas gangrene infection.

Objective To investigate the compliance and medication satisfaction in patients who received antiviral therapy.Methods Chronic hepatitis B and hepatitis C patients who had antiviral therapy from January 2008 to May 2011 in Center of Diagnosis,Treatment and Research for Teenagers Liver disease,302 Mihtary Hospital of China were chosen,and their compliance,medication satisfaction and reasons of bad treatment compliance werc investigated.Results Among chronic hepatitis B and hepatitis C patients who received antiviral therapy,82.80％ had good compliance,in which,91.86％ of hepatitis C patients and 80.57％ of hepatitis B had good compliance.Hepatitis C patients were better than hepatitis B patients in compliance,and the difference was statistically significant (x2 =6.177 3,P ＜ 0.05).The medication satisfaction of hepatitis B patients who had good compliance was lower than that of hepatitis C patients [(58.38 ±9.17) vs (59.62 ± 9.81)],and the difference was statistically significant (t =-1.050 1,P ＜ 0.05).Conclusions Treatment compliance and medication satisfaction degree are not as good as expected in patients who receive antiviral therapy,which are due to side effects of drugs,low therapeutic efficacy,lacking of medication monitoring and mistaken understanding of the diseases.

OBJECTIVETo screen and identify zebrafish mutants with erythropoiesis defects by N-ethyl-N-nitrosourea (ENU) mutagenesis and large-scale forward genetic screening using beta e 1 as the marker.

METHODSThe chemical mutagen ENU was used to treat healthy wild-type male fish (AB strain, F0). The surviving ENU-treated fish were mated with wild-type female fish to generate F1, and further F2 family was generated by F1 family intercross. The adult F2 fish were intercrossed within each F2 family and the resulting F3 embryos from each crossing were subjected to whole mount in situ hybridization (WISH) with the beta e 1 probe. Mutagenesis was performed by treating the male zebrafish with ENU to induce mutations in pre-meiotic germ cells to generate the founders, which were outcrossed to obtained the F1 fish. The F1 fish from different founders were mated to generate the F2 families. F3 embryos from the sibling cross in the F2 family were examined by whole mount in situ hybridization using beta e 1-globin probe. The putative mutants were then characterized with different hematopoiesis markers.

RESULTS AND CONCLUSIONWe identified 4 beta e 1-deficient mutants with erythropoiesis defects, including two with specific erythiod lineage defects and two with concurrent lymphopoiesis defects.

Objective To determine whether the combination of traditional risk factors and quantitative coronary angiography (QCA) assessment could provide accurate prognostic information on a population-based study including 1137 adults with subclinical artherosclerosis and with coronary risk factors. Methods Participants underwent coronary angiography examination before the minimal stenotic diameters, segment diameters, percent stenosis, plaque areas. Other parameters were analyzed by the computer-assisted Coronary Angiography Analysis System. The Framingham Risk Score for each participant was assessed. During the 1 year follow-up period, all kinds of endpoint cardiovascular events were screened. Endpoint events were defined as death from coronary heart disease, nonfatal myocardial infarction (MI) or unstable angina pectoris. Results During the 1 year of follow-up period, a total of 124 participants developed an endpoint event, which was significantly associated with the Framingham Risk Score, calcium of plaques and the plaque areas (all Ps＜0.05).The QCA score incorporated with the QCA parameters was related to the endpoint events. The Framingham Risk Score was combined with QCA score through logistic regression for prediction of end-point events. Data from the ROC analysis showed the accuracy of this prediction algorithm was superior to the accuracy when variables themselves were used. The event-free survival rate was inferior to the control group in participates under high risk, when being screened with this prediction algorithm (P＜0.05). Conclusion The risk of cardiovascular attack in subclinical artherosclerosis individual seemed to be associated with the Framingham Risk Score, calcium of plaques and the plaque areas. When the traditional risk factors (the Framingham Risk Score) were combined with QCA, the new method could provide more prognostic information on those adults with subclinical artherosclerosis.
