Objective Aimed at the problem that there is no curative effect standard of liver-qi invasion of premenstrual syndrome (PMS), to construct the reference standard of curative effect evaluation for the liver-qi invasion of PMS. Method Curative effect evaluation research of Jingqianping granule was designed by the principle of random, double blind, contrast and multicentre. Three hundred and fifty-six patients with liver-qi invasion of PMS were divided into two groups randomly, one was Jingqianping granule, the other was placebo. Patients were given Jingqianping granule and placebo respectively for two menstrual cycles and followed–up for three menstrual cycles. The reference standard of curative effect evaluation for the liver-qi invasion of PMS was constructed with daily rating of severity of problems form (DRSP). Result Jingqianping granule and placebo have therapeutic effect on the patients with liver-qi invasion of PMS, and Jingqianping granule was better than placebo. DRSP can be used as indexes of curative effect evaluation. Conclusion The initial establishment of the curative effect evaluation criterion of PMS liver-qi invasion provides the important foundation for profession criterion’s establishment.

Objective To observe the effect of compound fetal liver extract combined with antiviral therapy on liver fibrosis in patients with cirrhosis.Methods 60 patients with liver cirrhosis from April 2014 to July 2015 were randomly divided into treatment group and control group(n=30).The patients in control group were treated with conventional anti viral therapy , 30 cases in treatment group were treated with compound fetal liver extract combined with antiviral therapy postoperative.Results 1 month after treatment, the treatment group serum liver fibrosis HA, PCM value respectively(107.5 ±17.8,99.8 ±14.9)ng/mL, were lower than in the control group (138.4 ±15.2,124.1 ±18.1)ng/mL(P<0.05).1 month after treatment, the treatment group liver fibrosis collagen type IV, III procollagen value respectively(58.9 ±11.0,109.2 ±11.1)μg/L, were lower than in the control group (85.7 ±11.2,122.7 ±11.3)μg/L(P<0.05).Conclusion Compound fetal bovine liver extract combined with anti-viral therapy in patients with cirrhosis has good, better than the use of antiviral drugs alone.

Objective To investigate the expression and clinical significance of RegⅣand EGFR,PI3K proteins in gastric adenocarcinoma .Methods S-P immunohistochemistry was used to detect the expression of RegⅣand EGFR,PI3K proteins in pathological tissues of 73 cases with gastric adenocarcinoma and tumor -adja-cent normal gastric tissues .Results The positive expression rates of RegⅣand EGFR,PI3K proteins in 73 cases with gastric adenocarcinoma tissue were 50.7%(37/73),56.2%(41/73) and 69.9%(51/73) respectively, which were significantly different from the positive expression rates of tumor -adjacent normal gastric tissues ,be-ing 20.5%(15/73),19.2%(14/73),and 21.9%(16/73),respectively(P<0.05).The expression of RegⅣprotein was significantly correlated to differentiation degree ( P<0.05 ) and the expression of EGFR protein was significantly correlated to infiltrative depth,TNM stage,and lymph node metastasis(P<0.05).The expression of PI3K protein was significantly correlated to differentiation degree ,infiltrative depth,TNM stage and lymph node metastasis(P<0.05).There was positive correlation between the expressions of RegⅣ/EGFR,RegⅣ/PI3K and EGFR/PI3K proteins in gastric adenocarcinoma and the values of Spearman coefficient correlation were 0.325, 0.403 and 0.384,respectively(P<0.05).Conclusion RegⅣmay play an important role in gastric adenocarci-noma genesis and progression by activating EGFR /PI3K/Akt signaling pathway .

Objective:To explore the clinical effect of intravenous immunoglobulin combined with conventional therapy in the treatment of severe pneumonia in infants and children.Methods:Selected the January 2015 to April 2016 in our hospital for treatment of 88 cases of children with severe pneumonia were retrospectively analyzed,which 47 cases by routine treatment plus intravenous immunoglobulin protein (treatment group),41 cases of children only take routine therapy (control group),with a course of 2 weeks.Results:The symptoms of fever,dyspnea,cough,wheezing,pulmonary rales were improved faster in the treatment group than the control group (P＜0.05);after 2 weeks of treatment,IgG levels were significantly higher in the treatment group than the control group(P＜0.05);after 2 weeks of treatment,the serum IL-6 and TNF-α levels were significantly lower in the treatment group than the control group(P＜ 0.05);after 1 week of treatment,57.45％ of patients was cured in the treatment groups while only 34.15％ patients in the control group (P＜0.05).Conclusion:Intravenous immunoglobulin combined with conventional therapy in the treatment of infants with severe pneumonia can significantly improve the theraputic effect and enhance blood immunoglobulin levels.

Objective To systematically evaluate the effectiveness of diabetes self-management education through telemedicine on glycosylated hemoglobin (HbA1c). Methods Randomized clinical trials (RCTs) that assessed the effectiveness of remote diabetes self-management education in patients with diabetes were systematically reviewed using multiple electronic databases. The searching time was from database establishment to May 2015. These articles were analyzed after evaluation of their quality. Results Eight RCTs were included involving 2 047 patients.The results of Meta-analysis showed the effectiveness of remote DMSE on reduction of HbA1c of patients with type 2 diabetes was more significant than that of the control group [WMD=-0.50,95%CI (-0.88,-0.12),P < 0.05],while failing to support the effectiveness of remote DMSE on patients with type 1 diabetes [WMD=0.62, 95%CI(-0.19,1.43), P>0.05]. Conclusions Remote DMSE is effective to improve the glycemic control in patients with type 2 diabetes,while the effect on patients with type 1 diabetes is still not certain. Large-scale and multi-centered RCTs are needed to confirm its effectiveness.

Objective To evaluate the method of measurement of total scatter calibrate factor (Sc,p). Methods To measure the Sc,p at different depths on central axis of 6?MV, 15?MV photon beams through different ways. Results It was found that the measured data of Sc,p changed with the different depths to a range of 1%～7%. Using the direct method, the Sc,p measured depth should be the same as the depth in dose normalization point of the prescription dose. If the Sc,p ( fsz, d) was measured at the other depths, it could be obtained indirectly by the calculation formula. Conclusions The Sc,p in the prescription dose can be obtained either by the direct measure method or the indirect calculation formula. But emphasis should be laid on the proper measure depth.
