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.

This paper aims to develop a method for the determination of aloe-emodin, rhein, chrysophanol and physcion and study the pharmacokinetic properties of four anthraquinones in rat plasma after oral administration of gardenia and rhubarb decoction. The plasma concentrations at different time points of four anthraquinones were determined by HPLC-FLD method. Plasma samples were extracted with liquid-liquid extraction procedure. Plasma samples were separated on a C18 column (4.6 mm x 150 mm, 5 μm), using 0.2% acetic acid and methanol as mobile phase at a flow rate of 1.0 mL min(-1) with gradient elution. The excitation and emission wavelengths were set at 430, 525 nm, respectively. DAS 2.0 software was applied to calculate the pharmacokinetic parameters. The results showed four anthraquinones can be absorbed. The main parameters of aloe-emodin, rhein, chrysophanol and physcion were as follows: C(max) for aloe-emodin was (0.085 ± 0.058), (3.772 ± 1.152), (0.464 ± 0.267), (0.028 ± 0.008) mg x L(-1) respectively; t(max) for rhein was (1.042 ± 0.510), (0.805 ± 0.307), (1.167 ± 0.283), (0.616 ± 0.162) h respectively; t½ for chrysophanol was (3.557 ± 1.250), (6.879 ± 1.126), (5.196 ± 2.032), (4.337 ± 1.816) h; AUC(0-t) for physcion was (0.504 ± 0.130), (9.558 ± 1.106), (2.545 ± 1.554), (0.052 ± 0.018) mg x h x L(-1). This paper developed a selective, accurate and sensitive HPLC-FLD method for the simultaneous determination of four anthraquiones in rat plasma.

Objective To investigate the effects of L-Arginine(L-Arg) on microcirculation perfusion after banked-blood transfusion in rabbits with hypovolemia.Methods Thirty healthy male New Zealand white rabbits weighing 2.0-2.5 kg were randomly divided into 3 groups (n =10 each): groups Ⅰ-Ⅲ.Hypovolemia was induced by blood letting (20％ of blood volume) and the equal volume of banked-blood was transfused 30 min later in groups Ⅰ and Ⅲ.25％ L-Arg 300 mg/kg was injected iv 5 min before blood letting in group Ⅲ,and the equal volume of normal saline was injected in group Ⅰ.Group Ⅱ only received 25％ L-Arg 300 mg/kg.MAP,CVP and tip perfusion index (TPI) were recorded at before (T0) and after blood letting (T1),end of banked-blood transfusion (T2),1 h ( T3 ) and 2 h (T4) after banked- blood transfusion,and blood samples were taken for determination of plasma lactate and nitric oxide (NO) concentrations.Results TPI was higher at T2-T4,plasma lactate concentration lower at T1 -T4 and plasma NO concentration lower at T3,T4 in groups Ⅱ and Ⅲ than in group Ⅰ ( P ＜0.05).There was no significant difference in MAP between groups Ⅱ,Ⅲ and group Ⅰ ( P ＞ 0.05).MAP was lower at T1 in group Ⅲ than in group Ⅱ (P ＜ 0.05).There was no significant difference in CVP among the 3 groups( P ＞ 0.05).Conclusion Pretreatment with L-Arg can increase microcirculation perfusion,and has no effect on hemodynamics in rabbits with hypovolemia after banked-blood transfusion.

Objective To regard the implication of viruses particularly herpes in pemphigus vulgaris,and assess and compare the level of immunoglobulin G (IgG) antibodies against herpes simplex virus types 1 and 2 (HSV1 and HSV2),cytomegalovirus (CMV) and Epstein-Barr virus (EBV) in patients with pemphigus vulgarisand healthy people.Methods In this study,23 patients with pemphigus vulgaris and 26 healthy individuals comprised the experimental and control groups,respectively.Serum samples were taken from both groups;the levels of IgG antibodies against HSV1,HSV2,CMV and EBV were measured using ELISA.Results Immunoglobulin G titer was higher for all four viruses in the patient group in comparison to the control group.This difference was significant for anti-EBV,anti-CMV and anti-HSV2 (t=2.16,P＜0.05;t =4.76,P＜ 0.01;t=3.75,P＜0.01),respectively,but not significant for anti-HSV1 (t=0.52,P＞0.05).Conclusion Viruses including EBV,CMV,and HSV2 probably play a role in the pathogenesis of pemphigus in addition to the effects of genetics,toxins and other predisposing factors.In this study,no statistically significant relationship was observed between HSV1 and pemphigus vulgaris.More studies must be done in this regard.

Objective To explore the relationship between psychological problems in middle school students and parental rearing behaviors.Methods It was a cross-sectional study.By means of cluster sampling,2700 students selected from 7 middle schools in Nanning were investigated with Symptom Check List-90(SCL-90),the Egna Minnen Barndoms Uppfostran(EMBU) scale and the General Information Questionnair.Results The prevalence of psychological problems was 14.5%.Correlation analysis showed that the total score and factor-scores of SCL-90 had positive correlation with parental punishment,rejection,preference and overprotection.The total score and factor-scores of SCL-90 was negatively related to parental emotional concern.Conclusions Psychological problems in middle school students are closely related to parental rearing behaviors,and incorrect parental rearing behavior is one risk factor of psychological problems in the middle school students.

Objective To study the effectiveness and safety of lipo-PGE1 on proteinuria in patients with diabetic nephropathy. MethodsForty-eight cases suffering from diabetic nephropathy with proteinuria exceeding 0.5 g/d and stage Ⅱ-Ⅳ of chronic kidney disease were divided into two groups.The basic treatment scheme for all the patients includes insulin and/or oral antidiabetic drugs and anti-hypertension drugs.The patients in the control group were given dipyridamole,and those in the lipo-PGE1-treatment group were managed with lipo-PGE1(alprostadil injection),10 ?g,qd?14 d.Results After the treatment,a decrease in proteinuria and increase in serum albumin were observed in the lipo-PGE1-treatment group,which was superior to the control group(P

Objective To develop a rapid and efficient single cell PCR method for the non-invasive prenatal hemophilia A genetic diagnosis.Methods Six STR markers (DXS15,DXS9901,G6PD, DXS1073,DXS1108 and F8Civsl3) closely linked to F Ⅷ gene were examined in 118 healthy individuals and 12 hemophilia A families by muhi-plex fluorescent PCR.Three markers with the higher heterozygote rate and diagnostic rate were chosen and combined with amelogenin gene to establish the four-plex nested fluorescent PCR on single lymphocyte level.Results The single lymphocyte amplification rates of Amelogenin,DXS15,FSCivsl3 and DXSI073 were 94.3%,91.4%,100% and 100% in the normal male,and 100% ,97.1% ,97.1% and 97.1% in the normal female's respectively.The female was heterozygous in DXS1073 and DXS15.However,no allele dropout was found in both markers.Neither the false negative nor the false positive amplification was observed.Conclusion The single cell four-plex nested fluorescent PCR method established in this study is convenient and efficient,and will be hopefully employed in the clinical non-invasive prenatal genetic diagnosis for hemophilia A.

Objective To investigate the mechanisms modulating the functions of dendritic cells (DCs) and suppressing the activation and proliferation of T cells by transforming growth factor-β (TGF-β).Methods Mouse splenic DCs were purified with CD11c+ immunomagnetic beads and the purity of isolated DCs were detected by flow cytometry.Gene chip was used to detect gene expression in DCs after stimulation with TGF-β, and then real-time PCR was performed to analyze the differentially expressed genes in microarray at mRNA level.The activation and proliferation of CD4+ T cells which were co-cultured with DCs after stimulation with TGF-β were detected by flow cytometry.Results The purity of DCs reached over 95% after isolation.TGF-β down-regulated the expression of cell surface markers CD53, CD69, CD33, CD74 and CD93 on DCs;decreased the expression of chemokines Ccl3, Ccl5, Ccl9, Ccl6, Ccl17, Cxcl10, Ccl22, Ccl4, Ccr7, Ccl2, Cxcl9 and Ccl7;inhibited the expression of inflammatory cytokines IL-2ra, IL-12rb2, IL-15ra, IL-1b and IL-15.Moreover, the DCs-mediated activation and proliferation of CD4+ T cells were suppressed by TGF-β.Conclusion TGF-β inhibits the DCs-mediated activation and proliferation of CD4+ T cells by suppressing the expression of surface markers on DCs and down-regulating the expression of chemokines and inflammatory cytokines.

There were many factors that affect the chimerism of donor DNA, such as the type of disease, the treatment of the disease, the severity of the disease, the source of hematopoietic stem cells, HLA, GVHD, and so on. This paper mainly discussed the two factors that affect forensic science, including the posttransplantation intervals and sensitivity of the detection method. Forensic workers in forensic practice and paternity and individual identification of allo HSCT recipients, should pay attention to the time after transplantation and the detection method of sensitivity of chimerism. When female recipients received HSCT in the case of male donors, Y chromosome DNA of the donor can be detected from the recipient's hair follicles. The case of biological specimens from the crime scene can not only detect Y chromosome speciifc genetic markers, so as to avoid wrong identiifcation.
