Objective: To observe the therapeutic efficacy of acupoint application at different groups of acupoints in treating bronchial asthma in remission stage. Methods:A total of 120 patients with bronchial asthma in remission stage were recruited and divided by the random number table method into acupoint application group 1, acupoint application group 2 and acupoint application group 3, with 40 cases in each group. In all the three groups, Tiantu (CV 22), Dazhui (GV 14) and Feishu (BL 13) were selected, with Dingchuan (EX-B 1) added in acupoint application group 1, Shenshu (BL 23) added in acupoint application group 2, and Gaohuang (BL 43) added in acupoint application group 3. Before intervention, one month and 3 months after intervention, clinical symptoms, peak expiratory flow (PEF) andforced expiratory volume in 1 second percentage of predicted value (FEV1％) of the three groups were observed, and their clinical efficacies were evaluated. Results: Comparing the therapeutic efficacy regarding traditional Chinese medicine symptoms and signs, after 1-month treatment, the total effective rate was 87.5％ in acupoint application group 1, versus 62.5％ in acupoint application group 2 and 55.0％ in acupoint application group 3, and the between-group differences were statistically significant. After 3-month treatment, the total effective rate was 95.0％ in acupoint application group 1, versus 70.0％ in acupoint application group 2 and 65.0％ in acupoint application group 3, and the between-group differences were statistically significant. After intervention, the three groups all showed significant improvements in pulmonary function with statistical significance; among the three groups, the improvement in acupoint application group 1 was more significant than that in the other two groups. Conclusion: Tiantu (CV 22), Dazhui (GV 14) and Feishu (BL 13) as basic prescription plus Dingchuan (EX-B 1) can improve symptoms of bronchial asthma in remission stage, and it works better in improving pulmonary function than the basic prescription plus Shenshu (BL 23) or Gaohuang (BL 43).

The relationship of interleukin-4 (IL-4) C-33T and C-590T (C-589T) gene polymorphisms with allergic rhinitis was analyzed. Data about the case control studies of IL-4 gene promoter polymorphisms [C-33T and C-590T (C-589T)] and their association with allergic diseases and correlation between serum IL-4 levels and allergic rhinitis were retrieved. The Stata 12.0 statistical software was applied to analyze the correlation between IL-4 gene polymorphisms and allergic rhinitis. The meta-analysis result of TT/CC genotype of -590 (-589) polymorphism showed a significant association with allergic diseases [OR=1.93, 95% CI (1.61-2.31), P=0.00]. Meta-analysis of the TT+TC versus CC genotype of IL-4 C-33/T polymorphism revealed significant associations with allergic diseases [OR=3.23, 95% CI (1.13-9.25), P=0.03]. Meanwhile, there was a significant correlation between serum IL-4 levels and allergic rhinitis [OR=2.52, 95% CI=(1.80-3.23), P=0.00]. IL-4 gene -590 TT genotype may increase the risk of allergic rhinitis and the T allele mutation of -33 might be correlated with allergic rhinitis.

Objective To predict B cell epitopes in Sj22, Sj23, Sj14-3-3, Sj26 of Schistosoma japonicum with bioinformatics, and evaluate the antigenicity of these epitope proteins. Methods The complete DNA sequences of S.japonicum were predicted by BioSun system, the target B cell epitope genes were selected, cloned and expressed. The expressed fusion proteins were detected with the sera of schistosomiasis patients and health people for evaluation of their antigenicity. Results Eight B cell epitopes from four molecules of S.japonicum were predicted. The B cell epitopes of Sj22 probably located in 56-62 and 127-133 amino acids. The B cell epitopes of Sj23 probably located in 149-156 and 160-167 amino acids. The B cell epitopes of S14-3-3 probably located in 118-125 and 130-137 amino acids. The B cell epitopes of Sj26 probably located in 143-149 and 191-197 amino acids. The predicted epitope genes were cloned into pET-32c plasmid and expressed. Three of eight expressed fusion proteins of epitopes were reacted with the sera of schistosomiasis patients but not with health people. Conclusion Three epitope antigens with potential diagnosis value are determined.

OBJECTIVETo evaluate the role of sclerostin in bone loss of postmenopausal Chinese women with type 2 diabetes mellitus.

METHODSThe postmenopausal patients suffering from type 2 diabetes mellitus and age, body mass index, and duration of menopause matched healthy controls were enrolled into this cross-sectional study according to criteria of inclusion and exclusion. The serum sclerostin level and bone mineral density of the anterior-posterior lumbar spine (L1-L4), femoral neck, and total hip were determined by using a quantitative sandwich ELISA kit and dual X-ray absorptiometry, respectively. Meanwhile, the clinical and laboratory indexes of bone mineral metabolism were analyzed. Associations between serum sclerostin level and bone mineral density as well as bone turnover markers were evaluated by linear regression analysis.

RESULTSFinally, 265 postmenopausal women with type 2 diabetes and 225 non-diabetic women were recruited in the diabetic group and control group, respectively. Serum sclerostin level of the diabetic group was significantly higher than that of the control group (48.2±19.4 vs. 37.2±18.6 pmol/L, P<0.001) and was increased with age in both groups (diabetic group, r=0.374, P<0.001; control group, r=0.312, P<0.001). In type 2 diabetes patients, serum sclerostin concentration was positively correlated with hemoglobin A1c level (r=0.237; P=0.021). Biochemical bone turnover markers, intact parathyroid hormone and bone-specific alkaline phosphatase, were negatively associated with serum sclerostin level (r=-0.138, P=0.078 and r=-0.265, P<0.001). Conversely, the positive correlation between sclerostin and C-terminal cross-linking telopeptide of type I collagen was found in diabetic patients (r=0.354, P<0.001). Serum sclerostin levels of the diabetic group were positively correlated with bone mineral density of the lumbar spine, femoral neck, and total hip (r=0.324, 0.367, and 0.416, respectively; all P<0.001).

CONCLUSIONSSclerostin might participate in the pathogenesis of bone loss of type 2 diabetes. The high sclerostin level might serve as a marker of increased osteocyte activity in postmenopausal patients with type 2 diabetes mellitus.

OBJECTIVETo discuss the mechanism of traditional Chinese medicines reducing phlegm and resolving masses in treatment of iodine deficiency-induced goiter by observing the expression of growth factors and the balance-regulating mechanism of proliferation and apoptosis.

METHOD180 four-week-old Wistar rats were selected to establish the iodine deficiency model. After the modeling, the rats were randomly divided into six groups: the normal control group, the model control group, the iodine group, the phlegm compound group, the L-T4 group and the phlegm compound and L-T4 group. At the 21st day and 77th day after administration, 15 rats in each group were killed to collect specimens. Doses were calculated and adjusted according to body surface area and body weight. TT3, TT4 radioimmunoassay, TSH, immunoradiometric method were adopted. Fas, FasL and PCNA protein expressions are detected using immunohistochemical methods.

RESULTCompared with the normal group and the model group, the expressions of fas and FasL in the phlegm Group significantly increased, the expressions of fas and FasL in the phlegm and L-T4 group were also increased significantly. The expression of fas in the L-T4 Group was significantly lower than that of the L-T4 group and the phlegm compound and L-T4 group. Compared with the normal group, the expression of PCNA of the phlegm group and the phlegm and L-T4 group was significantly lower. Compared with the model group, the expression of PCNA of the iodine group, the phlegm groups and the phlegm and L-T4 group were significantly lower. Compared with the normal group, the expression of VEGF in the iodine group significantly decreased after treatment. Compared with the iodine group, the expression of VEGF in the phlegm group and the L-T4 group significantly reduced. Compared with the normal group, the expression of TGF-beta1 in the model group and the phlegm group significantly increased. Compared with model group, the expression of TGF-beta1 in the iodine group significantly reduced. Compared with the phlegm group, the expression of TGF-beta1 in the phlegm compound and L-T4 group was significantly reduced.

CONCLUSIONTraditional Chinese medicines reducing phlegm and resolving masses can completely recover goiter by promoting apoptosis of thyroid cells, inhibiting their proliferation and the expression of growth factors and enhancing the expression of TGF-beta, without causing injury on thyroid cells.

Objective: To analyze the effect of acupuncture versus hormone replacement therapy (HRT) for premature ovarian insufficiency (POI). Methods: China National Knowledge Infrastructure (CNKI), Wanfang Academic Journal Full-text Database (Wanfang), Chongqing VIP Database (CQVIP), China Biology Medicine Disc (CBM), Web of Science, Cochrane Library, PubMed, and Excerpta Medica Database (EMBASE) were searched up to January 31st, 2019 to identify randomized controlled trials (RCTs) evaluating the effect of acupuncture for POI. The primary outcome was the level of basal serum follicle- stimulating hormone (FSH). Secondary outcomes included serum levels of luteinizing hormone (LH), estradiol (E2) and anti-Müllerian hormone (AMH). Two authors extracted data independently and assessed the risk of bias and the methodological quality using the Cochrane's tool. Meta-analysis was conducted by RevMan version 5.3. Results: Eight eligible RCTs with a total of 496 POI patients were included in the meta-analysis. The pooled results showed that there was a significant reduction in the basal serum FSH level (MD=-5.82, 95％CI:-9.76 to -1.87, I2=82％, P=0.004) and a remarkable elevation in the basal E2 level (SMD=0.93, 95％CI: 0.34 to 1.52, I2=88％, P=0.002) in the acupuncture group when compared with the control. Subgroup analysis showed that compared with HRT, a significant decrease in the FSH level was observed in both acupuncture alone (MD=-4.53, 95％CI:-8.96 to -0.10, I2=73％, P=0.04) and acupuncture plus HRT (MD=-9.60, 95％CI:-17.60 to -1.61, I2=50％, P=0.02), while a remarkable elevation of E2 was only found in acupuncture plus HRT (SMD=1.43, 95％CI: 1.03 to 1.82, I2=0％, P<0.00001). There was no significant difference in the LH level between acupuncture and HRT (MD=-3.16, 95％CI:-9.41 to 3.10, I2=0％, P=0.32), only one trial reported AMH, and no significant difference was found between acupuncture and HRT. Conclusion: The present study indicated that acupuncture had an advantage over HRT in reducing serum FSH level and increasing serum E2 level in women with POI. However, evidence supporting the finding is limited due to the small sample size, potential methodological flaws and significant heterogeneity. Hence, this conclusion still needs to be verified by high-quality RCTs.

Breast cancer has the highest incidence rate among all women's malignant tumors worldwide.Surgery,radiotherapy and chemotherapy are three major treatments,while most patients showed adverse effects or complications during or after the treatment,including lymphedema,gastrointestinal reactions and leukopenia,which cause severe impact on patients' recovery and quality of life.Moxibustion has been used and certified to alleviate adverse effects of surgery or chemoradiotherapy for breast cancer.We have summarized literatures in recent years and suggest more systematic research in the future for the underlying mechanism.

Background and purpose:Although there is still no standard ifrst line chemotherapy regimen for metastatic gastric cancer (MGC), the doublet and triplet regimens containing platinum and lfuorouracil were most popular worldwidely. The ECF regimen is the classical and one of the most popular treatment choices in this setting, while the marrow suppression, the renal toxicity and poor compliance inhibits its usage. In order to improve its efifcacy and tolerability, this study conducted 2 phaseⅡ trials by modified ECF regimen, the EOF5 regimen (substituting cisplatin with oxaliplatin, shortening the continuous infusion period to 120 h), to treat patients with MGC since 2004. This paper reported the comprehensive results of the 2 studies.Methods:All the patients who enrolled in our previous2 phaseⅡ trials and received EOF5 as ifrst line treatment entered this study. Each patient received the treatment of epirubicin 50 mg/m2 iv d1, oxaliplatin 130 mg/m2 iv gtt d1 and 5-FU 375-425 mg/m2·d-1 civ 120 h, and repeated every 3 weeks. Efifcacy was analyzed every 6 weeks.Results:A total number of 178 patients (all were metastatic patients but 2 advanced patients with unresectable lesions) were included into this study. One hundred and seventy patients were evaluable, and 7 patients (3.9%) achieved complete response (CR), 76 patients (42.7%) achieved partial response (PR), 46.6% patients achieved overall response rate (ORR, CR+PR), and the cases of stable disease (SD) and progressive disease (PD) were 69 (38.8%) and 18 (10.1%), respectively. The median progress free survival (PFS) and overall survival (OS) were 6.0 months (95%CI: 5.2-6.8) and 12.6 months (95%CI: 8.9-16.3), 1-year and 2-year survival rate were 50.9% and 28.0%, respectively. Grade 3, 4 toxicity including: leucopenia (23.0), neutropenia (38.8%), anemia (6.5%), thrombocytopenia (23.5%), nausea/vomiting (14.1%), and peripheral neuropathy toxicity (1.2%). Among 75 patients who received second line treatment, the median survival from second line treatment was 8.0 months (95%CI: 4.8-11.2).Conclusion:EOF5 regimen is a highly effective regimen with moderate and manageable toxicity, and it providesa suitable alternative for the ifrst-line treatment of MGC.

BACKGROUNDTo express the prM-E protein in Sf9 cells, and lay a basis for further study on the function of the viral proteins and development of specific diagnostic reagents.

METHODSThe recombinant prM-E protein of tick-borne encephalitis virus was expressed in insect cell Sf9 by RT-PCR amplification of prM-E gene, construction of donor plasmid of Bac-to-Bac baculovirus expression system, homologous recombination of donor plasmid with bacmid DNA at the site of Tn7 and transfection of insect cell Sf9.

RESULTSRecombinant subviral particles, about 30 nm in diameter, consisting of prM-E were observed by electron microscope in the supernatant of infected cells, which indicated that infected cells released virus-like particles (VLPs) into the culture medium. The results of Western-blot and the indirect immunofluorescence assay (IFA) showed that the recombinant proteins retained antigenic and conformational structures similar to those of native virus proteins. Using the recombinant prM-E as antigens to detect samples of patient sera by ELISA and IFA, all of 16 sera from patients with tick-borne encephalitis were positive and all of 6 sera from other patients were negative.

CONCLUSIONThe prM-E protein expressed in insect cells retains good antigenicity.
