Objective To systematically evaluate the curative effect and safety of treating winter diseases in summer acupoint application therapy for asthma in children.Methods The domestic and international databases were retrieved till Feb 2017.The randomized controlled trials about treatment of treating winter diseases in summer acupoint application therapy for children with asthma were identified.The methodology quality of included trials was assessed.Results A total of 3 RCT involving 146 patients were included.The compositions of Chinese medicines and acupuncture points used were quite diverse,which inhibited us to conduct meta-analysis.The methodological quality of included RCT was generally lower.The results showed that treating winter diseases in summer acupoint application therapy might have advantage in reducing asthma acute attack times and improving clinical symptoms and respiratory function.Conclusion treating winter diseases in summer acupoint sticking therapy for asthma in children may have some advantages,however,due to the lack of a number of trials and poor methodology quality,the claimed benefits of treating winter diseases in summer acupoint sticking therapy for for children with asthma are inconclusive;more rigorous studies are warranted to support clinical practice.

Objectives To investigate the value of hepatobiliary scintigraphy in evaluation of the hepatic uptake and excre-tion function in neonatal intrahepatic cholestasis caused by citrin deifciency (NICCD). Methods Hepatobiliary scintigraphy with SPECT was used to detect the hepatic uptake and excretion function of 12 patients with NICCD conifrmed by SLC25A13 gene analysis, and the results were compared with the results of blood biochemical tests. Results The hepatic uptake and excretion function were obviously impaired in all of 12 NICCD patients in the initial scintigraphy. The scintigraphy were performed again in 5 patients in the follow-up after treatment, and showed that the hepatic uptake and excretion function was recovered. It was sug-gested that the hepatic uptake and excretion function was consistent with the level of liver enzymes and the degree of cholestasis. Conclusions Hepatobiliary scintigraphy is of value in evaluation of the hepatic uptake and excretion function in NICCD patients.

Vertebral artery dominance is generally considered to be a congenital vascular variation or meaningless clinical finding.Many studies have shown that the bilateral vertebral artery blood flow asymmetry caused by vertebral artery dominance is easy to result in basilar artery curvature.Some studies have shown that there are certain correlations between both the vertebral artery dominance and the basilar artery curvature and the posterior circulation stroke.

Cerebral smal vessel disease (CSVD) can be divided into sporadic and hereditary CSVD. The exact pathogenesis of sporadic CSVD is unknow n. Genetic factors may also play an important role, except for environmental and vascular risk factors. As a complicated disease, sporadic CSVD has the characteristics of multigenetic susceptibility. Therefore, investigating the related genetic factors may contribute to understanding the pathogenesis of sporadic CSVD. This article review s the advances in research on the genetics of sporadic CSVD.

Objective To investigate the prevalence of nutritional risk,undemutrition,overweight/obesi-ty,and apphcation of nutrition support in departments of neurology in 3 metropolitan hospitals in Beijing. Methods Adult patients in the departments of neurology from 3 metropolitan hospitals in Beijing were consecutively en-rolled from March 2005 to March 2006.Nutritional Risk Screening 2002(NRS2002)score≥3 was defined a8 nu-tritian risk,while body mass index(BMI)<18.5 ks/m2 as undemutrition.NRS2002 was performed on the next morning of admission and nutritional support evaluation was performed on the 14th day of admission or discharge day.The relationship between nutrition risk and nutrition support was analyzed.Results A total of 753 patients were enrolled.NRS2002 scoring results were obtained in 461 patients.The prevalence of undemutrition was 4.2%and nutritional risk Was 21.2%.Among them 292 cases in undemutrition category were estimated by semm albu-min<30g/L without accurate BML If the cases without accurate BMl were excluded,the prevalence of undemutri-tion was 5.4%and nutritional risk Was 10.8%.Twenty-three patients(14.4%)with NRS2002≥3 received nutrition support.Thirteen patients(2.2%)with NRS2002<3 received nutrition support.The average PN:EN ratio Wag 1:2.Conclusions A large proportion of inpatients were at nutritional risk or undemutrition in the de-partments of neurology in metropolitan hospitals in Beijing.The application of nutrition support Wag somehow inap-propriate in these patients.Evidence-based guidelines are required to improve this situation

Objective To explore the effect of liver-soothing therapy on the expression of estrogen receptors mRNA in perimenopausal syndrome (PMS) rats with liver qi stagnation. Methods A total of 30 nature aging rats are assigned into control groups (n=8), model groups (n=8),Chaihu-Shugan San (CHSGS group,n=8) andDanzhi-Xiaoyao San (DZXYS group, n=8), according to the random number table. The PMS liver-Qi stagnation syndrome rat models were established by the methods of isolation raised and chronic bondage in all the groups except the control group. CHSGS group were administered 4.0 g/kg water decoctions ofChaihu ShuganSan, and DZXYS group 4.9 g/kg water decoctions ofDanzhi XiaoyaoSan respectively for 3 weeks after the rat models established. The model group and control group were administered with equal volume of normal saline. The open field test was used for the behavior test. The serum E2, FSH, LH level were measured by radioimmunoassay. The ERα, ERβ in ovary were measured by quantitative real-time PCR. Results Compared with model group on the 21st days, the CHSGS and DZXYS groups showed a significantly increase in crossings (49.6 ± 6.0, 51.6 ± 5.8vs. 40.0 ± 4.6,P<0.05 orP<0.01) and rearings (14.1 ± 0.7, 14.6 ± 2.3vs. 10.9 ± 1.8,P<0.05 orP<0.01). Cmpared with the model group, the FSH (3.96 ± 0.48 mIU/mlvs.5.31 ± 0.41 mIU/ml) significantly decreased in the CHSGS group, and the LH (6.65 ± 0.46 mIU/mlvs. 8.10 ± 0.62 mIU/ml) significantly decreased in the DZXYS group (P<0.05). Compared with the model group, ER alpha mRNA expression (7.42 ± 2.54, 4.91 ± 1.76vs. 3.80 ± 1.36,P<0.01) significantly increased in the CHSGS group, and the ER beta mRNA expression (3.56 ± 0.95vs. 3.10 ± 1.12,P>0.05) increaed in the DZXYS group, but there was no remarkable difference. Conclusion The Liver-soothing therapy can improve the behavior of PMS rats with liver-Qi stagnation, and the mechanism may be related to the regulation of endocrine and ovarian estrogen receptors.

Objective To clarify the MRI characteristics and outcomes of patients with end stage hypertrophic cardiomyopathy (ES-HCM).Methods Clinical and MRI data of 57 ES-HCM patients were retrospectively analyzed.ES-HCM pa tients were divided into dilated phenotype group (D-ES group,n=39) and restrictive phenotype group (R-ES group,n=18).MRI characteristics and outcomes of patients were compared between both groups.Results The incidence of atrial fi brillation and edema of lower extremity was significantly higher in R-ES than those in D-ES (72.22％ [13/18] vs 30.77％ [12/39];50.00％ [9/18] vs 23.08％ [9/39];both P＜0.05).The left ventricular ejection function,left and right atrial anteroposte rior diameter of D-ES group were significant smaller than those of RRES group (all P＜0.05),while the left ventricular (LV) short axis diameter,LV end diastolic/systolic volume and LV end diastolic/systolic volume index of D-ES were significantly greater than those of R-ES group (all P＜0.05).Log-rank test found no significant difference between both groups in cardiovascular death/ heart transplant events (x2 =1.135,P=0.287).Late gadolinium enhancement (LGE) volume fraction was significantly larger in D-ES ([36.1±14.8]％) than in R-ES ([21.0±9.0]％;P＜0.05).There was a significant correlation between LGE volume fraction and cardiovascular death/heart transplant events (HR:1.054,P＜0.05).Conclusion ES-HCM patients have expanded clinical expression and MRI characteristics,including dilated phenotype and restrictive phenotype.MRI has an important application value in the diagnosis and prognosis evaluation of ES-HCM.

Objectives To investigate the effects of lipoxin receptor agonist BML-111 on IFN-βand IE86 mRNA expression of macrophages infected by human cytomegalovirus (HCMV). Methods Macrophages were infected with HCMV (MOI=0.5), and the cultured cells were randomly divided into control group, HCMV group, HCMV+BML-111 group, and HCMV+MP group. The cells were collected at 0,1,2,4,8 and 12 h after infection, and the levels of IFN-βand IE86 mRNA were tested by real-time PCR. Results Compared with HCMV group, the levels of IFN-βmRNA in HCMV+BML-111 group increased significantly (P < 0.05), while the levels of IFN-βmRNA in HCMV+MP group decreased significantly (P < 0.05); Compared with HCMV group, there were no significant differences of the levels of IE86 mRNA in HCMV+BML-111 group (P>0.05), while the levels of IE86 mRNA in HCMV+MP group increased significantly (P < 0.05). Conclusion BML-111 exerts antiviral activity by promoting the expression of IFN-βmRNA at the early stage of HCMV infection.

BACKGROUND:The anti-inflammation and protective effects of lipoxin have been verified in several immunity-related disease models. Preliminary studies of our research group have shown that, lipoxin receptor agonist BML-111 has negative regulation effects on the human cytomegalovirus (HCMV)-induced immunological injury. However, the effect of BML-111 on the HCMV replication remains unclear.
OBJECTIVE:To observe the influence of lipoxin receptor agonist BML-111 on HCMV replication and proliferation in THP-1 macrophages and human embryonic lung fibroblasts.
METHODS:THP-1 macrophages were infected by HCMV AD169 strain, and were divided into three groups:mock infection, HCMV infection, HCMV+BML-111. The final concentration of BML-111 was 100 nmol/L. cells in each group were col ected at 0, 1, 2, 4, 12, 36, 48 hours, the mRNA levels of IE86 and pp65 in the THP-1 macrophages were tested by RT-PCR method. Human embryonic lung fibroblasts were infected with HCMV (MOI=0.1), and were divided into two groups:HCMV infection and HCMV+BML-111. The patho-morphous changes of human embryonic lung fibroblasts were observed under light microscope, and the cellnumber was measured. The infective virus titer changes in human embryonic lung fibroblasts were examined by plaque assay.
RESULTS AND CONCLUSION:After the macrophages were infected by HCMV, compared with the mock infection group, the mRNA levels of IE86 and pp65 in the HCMV group and HCMV+BML-111 group were increased significantly;compared with the HCMV infection group, the mRNA levels of IE86 and pp65 in the HCMV+BML-111 group were increased significantly in the early stage (within 4 hours) after infection, but the pp65 mRNA levels were decreased significantly in the medium and late stages (24-72 hours) after infection. After human embryonic lung fibroblasts were infected by HCMV, the degree of the patho-morphous in the HCMV+BML-111 group reached 100%2 days earlier than the of HCMV infection group. The infective virus titer reached the peak 2 days earlier than the HCMV infection group, but no significant difference was found between the two groups. BML-111 accelerates the replication of HCMV in the early stage of infection, but inhibits the expression of pp65 gene in the late stage. BML-111 has no impact on the proliferation of the infective HCMV titer in vitro.

Objective To investigate the dynamic expressions of epidermal growth factor receptor (EGFR) in mice with liver fibrosis and the effect of bone morphogenetic protein-7 (BMP-7) intervention on the expression of EGFR,and to explore a new therapy target for fibrosis.Methods A total of 30 healthy male ICR mice were randomly divided into three groups:6 mice in control group,18 mice in hepatic fibrosis group and 6 mice in BMP-7 intervention group.The model of mice with liver fibrosis was established by subcutaneous injection of carbon tetrachloride (CCl4) for 12 weeks.After administration of CCl4 for 8 weeks,human recombinant BMP-7 was given into mice in intervention group by intraperitoneal injection for 4 weeks.Hematoxylin-Eosin and Masson staining of liver tissues were employed to observe the pathological changes,and the semi-quantitative analysis of liver fibrosis was performed.Blood withdrawn from inferior vena cava was detected for levels of alanine aminotransferase (ALT),aspartate aminotransferase (AST) and albumin (Alb).The expressions of transforming growth factor-β1 (TGF-β1)mRNA and TGF-β1,EGFR,phosphorylation EGFR (pEGFR) protein in each group were detected using quantitative real time polymerase chain reaction and Western blot.Measurement date was compared using analysis of variance and Pearson correlation analysis.Results The model of mice with liver fibrosis was successfully established.In model group,the serum levels of ALT and AST increased,while the level of Alb decreased gradually.All these biochemical index improved after intervention of BMP-7 (ALT:[153.9±18.1] U/L vs [191.3±24.5] U/L;AST:[177.8±19.2] U/L vs [206.6±25.0] U/L;Alb:[25.4±0.9] g/L vs [22.2±1.2] g/L; all P＜0.05).With the progress of fibrosis,TGF-β1,EGFR and pEGFR protein expressions increased gradually in model group and reached a peak at week 12,which was significantly different compared to the control group (all P＜0.05).In BMP-7 intervention group,the expressions of the three proteins decreased significantly compared to model group (TGF-β1:0.256 ± 0.006 vs 0.287±0.014,EGFR:1.061±0.017 vs 1.094±0.014,pEGFR:0.855±0.053 vs 1.007±0.063;all P＜0.05).Additionally,linear correlation analysis showed that expressions of both EGFR and pEGFR proteins were positively correlated with TGF-β1 protein (rs =0.895 and 0.859,respectively; both P＜0.05).Conclusions BMP-7 can suppress the pathogenesis of mouse liver fibrosis.The mechanism may rely on the regulation of EGFR and TGF-β1 expressions.
