Objective To discuss the change of sympathetic skin response (SSR) in patients with cerebral thrombosis with no more than 60 years old. Method SSR was measured in four positions of the center of hand palm and foot palm of 40 normal controls ( control group ) and 56 cerebral thrombosis patients (cerebral thrombosis group) no more than 60 years old. Results SSR wave shape was all educed in control group,but 21 limbs (21/224,9.4%) were not educed in cerebral thrombosis group, SSR abnormality was 80 limbs (35.7% ). SSR's latency in cerebral thrombosis group was obviously prolonged as compared with control group,and the amplitudes of SSR of upper limps and lower limbs had significance between two groups (P< 0.05 or < 0.01). There were serious abnormity within 3 days to 2 months after cerebral thrombosis. Conclusion SSR is a sensitive diagnosis method for the autonomic neuropathy of cerebral thrombosis patients of no more than 60 years old.

Objective:To investigate the influence of chemotherapy on the phenotype of secreted protein, acidic and rich in cysteine (SPARC) in gastric cancer (GC). Methods:Immunohistochemistry was used to analyze SPARC expression in 132 GC patients. Among these patients, 54 with preoperative chemotherapy and 78 without preoperative chemotherapy were selected to analyze the effect of chemotherapy on SPARC phenotype by comparing the postoperative specimens of the two cohorts. Results:SPARC expression was higher in GC lesions than in the desmoplastic stroma surrounding the tumor cells and noncancerous tissues. High SPARC expression was related to invasion depth, lymph node metastasis, and TNM staging. SPARC expression was lower in patients with preoperative chemotherapy than in controls ( P<0.05). Gross type, histology, depth of invasion, lymph node metastasis, TNM staging, and SPARC phenotype correlated with the overall survival of the patients with preoperative chemotherapy. Further multivariate analysis suggested that lymph node metastasis, histology, and SPARC phenotype after chemotherapy were independent prognostic indicators of GC. Conclusion:SPARC expression was associated with invasion depth, lymph node metastasis, TNM staging and GC prognosis. Preoperative chemotherapy may change the phenotype of SPARC in GC patients.

Choosing the right solvent and timely use is the basis of rational drug use and the most direct and efficient way to improve the safety of traditional Chinese medicine injections. This study aimed to evaluate the influence of solvent and drug preparation time on Shuanghuanglian injection inducing pseudo-allergic reactions with mouse mode. The two tests were carried out: (1) Comparative experiment between different solvent: Shuanghuanglian injection preparation to the appropriate concentration with 0.9% sodium chloride injection and 5% dextrose injection, mixed with Evans blue, at one time intravenous injected into mice, 30 minutes later, the mouse ears vascular permeability were observed and compared. (2) Comparative experiment among different preparation time: placed 10 min, 2.5 h, 6 h and 24 h after Shuanghuanglian injection were prepared and then to detect the pseudo-allergic reactions in mice using the same methods as in (1). The results showed that there was no significant difference in the pseudo-allergic reactions in mice which induced by the same dose of Shuanghuanglian injection, respectively with 0.9% sodium chloride injection and 5% dextrose injection preparation, and with the extension of preparation time, the degree of pseudo-allergic reactions of Shuanghuanglian injection was gradually severe.

To evaluated the pseudo-allergic reactions of cordate houttuynia, pulse-activating and Qingkailing injection in mice, the ICR mouse were divided into different test groups, then were intravenously injected with three traditional Chinese medicine injections, positive control compound 48/80 and physiological saline as normal control. All test substances were mixed with 0.4% Evans blue. The reaction and vascular permeability of the ears were observed and measured 30 min after injection. At the same time, the mechanisms of the traditional Chinese injections' pseudo-allergic reactions was studyed. ICR mice were injected with the test substances as above without EB, blood in a part of mice were collected after 5 min, and the level of histamine in the plasma were measured. Blood in the other part of mice were collected after 30 min, and the level of VEGF, TNF-α and IL-10 in the serum were measured. The reasults showed that except the cordate houttuynia injection, pulse-activating injection in 1. 5 times clinical concentration and Qingkailing injection in 3.3 times clinical concentration caused mild pseudo-allergic reactions mainly for vascular permeability, no pseudo-allergic reactions occurred when the concentration of the two injections was below the concentration metioned above; 5 minutes after intravenous injection of the three TCM injections into ICR mice with the highest dose, the levels of histamine in plasma of pulse-activating injection and Qingkailing injection groups were increased significantly, 30 minutes later, the levels of VEGF, TNF-α and IL-10 in the serum of all groups were no significant change compared to normal group. The mouse of pulse-activating and Qingkailing injection groups showed inflammatory changes in ear and lung tissues. It can be conluded that when the dose or concentration increased to a certain extent, pulse-activating and Qingkailing injection could induce pseudo-allergic reactions on ICR mice, the increased histamine realease maybe the main reason for pseudo-allergic reactions of the two traditional Chinese medicine injections. In addition the author preliminary thought that inflammatory mechanisms leading to hyperpermeabilities were the main reason of the traditional Chinese medicine injection's pseudo-allergic reaction.

Objective The aim of this study was to systemically analyze the epidemiologic,serological and genetic characteristics of hepatitis E virus (HEV) in Shanghai from 1997 to 2012.Methods We analyzed the data related to the epidemics of hepatitis E from China Information System for Disease Control and Prevention.We implemented serological surveillance program,based on community healthy population with enzyme-linked immunosorbent assay method and estimated the standardized sero-prevalence.We also obtained nucleotide sequences of hepatitis E patients using the nested RT-PCT assays,together with propotype sequences in the GenBank to construct a HEV genetic database in Shanghai.Results In this paper,we found that the distribution of hepatitis E patients was sporadic in the past 16 years in Shanghai.The morbidity kept declining,but with seasonal and periodical fluctuation.Morbidity in males was significantly higher than in females,with the hard hit population between 30 and 65 year-olds.In total,3979 sera samples were collected through the serological surveillance programs in 2001,2004,2007 and 2012.The standardized sero-prevalence rates of the said years were 22.32％,18.56％,10.22％ and 34.43％ which all showing strong relationship with age groups and the regions where the populations were being monitored.73 nucleotide sequences of hepatitis E patients from hospitals were identified,during 2004 and 2008.Results from phylogenetic analysis revealed that all HEV isolates belonged to genotype Ⅳ and including 4 known subtypes 4a,4d,4h and 4i which sharing 83.09％-97.96％,85.87％-97.26％ and 83.80％-95.10％ nucleotide sequence identities with the swine HEV genotype Ⅳ of GU188851,DQ450072 and EF570133.Meanwhile,59 HEV isolates from different districts shared 99％ nucleotide sequence identities with each other.Conclusion Hepatitis E would still be a challenge for long time and the zoonotic questions that related to hepatitis E,need to be explored and explained in the future.

Objective To investigate the mechanism of Guizhi Fuling Pills in the treatment of polycystic ovary syndrome(PCOS)and endometriosis(EMT).Methods TCMSP was utilized to obtain the active ingredients and related targets of the constituent Chinese medicines of Guizhi Fuling Pills.GeneCards,PharmGKB,and TTD databases were used to screen PCOS and EMT disease targets,respectively.The Venn R diagram was drawn after obtaining the intersecting targets of drugs and diseases using the Venn R package in R software,the drug-active ingredient-potential target interactions network diagram was made in Cytoscape,the intersecting target protein-protein interactions(PPI)network diagram was drawn in the STRING platform,and Cytoscape was used to optimize the PPI network and screen the core targets.R language was applied for Gene Ontology(GO)enrichment and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analysis,and AutoDockTools was for molecular docking.Results A total of 85 active ingredients and 191 corresponding targets of Guizhi Fuling Pills were obtained,and 77 potential targets of Guizhi Fuling Pills for the treatment of PCOS and EMT.The core active ingredients of Guizhi Fuling Pills for PCOS and EMT were quercetin,β-sitosterol,kaempferol,hederagenin,baicalein,and the core targets were AKT1,EGFR,IL-6,TNF,and TP53.GO functional analysis yielded 2 020 biological process,34 cellular components,126 molecular functions,and KEGG enrichment analysis yielded 165 signaling pathways.Molecular docking showed that the core components in the formula docked well with the targets.Conclusion Guizhi Fuling Pills may regulate the signaling pathways of lipid and atherosclerosis,AGE-RAGE signaling pathway,fluid shear stress and atherosclerosis,and chemical carcinogenesis-receptor activation through quercetin,β-sitosterol,kaempferol,hederagenin,and baicalein,and act on AKT1,EGFR,IL-6,TNF,and TP53,thus treating PCOS and EMT with homotherapy for heteropathy.

Objective To screen the optimal regimen of Chinese medicine combined with hormones for the treatment of premature ovarian failure(POF)using network meta-analysis and to provide an evidence-based basis for the clinical treatment of POF.Methods The randomized controlled trials(RCTs)of Chinese medicine combined with hormones in the treatment of POF were retrieved from thhe domestic and oversea databases of CNKI,VIP,Wanfang,CBM,PubMed,Cochrane,Embase,and Web of Science.The quality of the literature was assessed using the tools for analysis of bias recommended by Cochrane Reviewer's Handbook and by Jadad scale scores.Rstudio and StataSE 15.1 statistical software were used to perform network meta-analysis and graphical presentation of the data.Results A total of 50 RCTs were included,covering 8 intervention methods.The overall risk of bias of the included studies was low,but the quality of the literature was generally low.The results of network meta-analysis showed that,in terms of the effective rate,the intervetion of 7 various Chinese medicines combined with hormone was superior to the conventional treatment(hormone replacement therapy,HRT)in the control group,and Nuangong Qiwei Powder+HRT was superior to the remaining 6 kinds of Chinese medicines combined with HRT;with reference to the values of the surface under the cumulative ranking curve(SUCRA),the efficiencies of the effective rate of the 8 intervention methods in descending order were Nuangong Qiwei Powder+ HRT(SUCRA=81.2),Zishen Yutai Pills + HRT(SUCRA=80.0),modified Zuogui Pills + HRT(SUCRA= 66.1),Ankun Zhongzi Pills + HRT(SUCRA=49.6),Kuntai Capsules + HRT(SUCRA=45.2),modified Erxian Decoction + HRT(SUCRA=39.5),Liuwei Dihuang Pills + HRT(SUCRA=37.4)and HRT(SUCRA=1.0).In terms of improving serum follicle-stimulating hormone(FSH)levels,modified Zuogui Pills + HRT was superior to the remaining 7 intervention methods;with reference to the values of the SUCRA,the efficiencies of the 8 intervention methods in descending order were modified Zuogui Pills + HRT(SUCRA=97.0),HRT(SUCRA= 77.9),Liuwei Dihuang Pills + HRT(SUCRA=76.6),Kuntai Capsules + HRT(SUCRA=46.5),Nuangong Qiwei Powder+HRT(SUCRA=38.9),Ankun Zhongzi Pills + HRT(SUCRA=29.9),modified Erxian Decoction + HRT(SUCRA=18.1),and Zishen Yutai Pills + HRT(SUCRA=15.1).Conclusion All kinds of Chinese medicines combined with HRT exert stronger effect on improving the primary outcome indicators than HRT alone for the treatment of POF.The intervention with Nuangong Qiwei Powder+HRT exerts the highest probability of the optimal regimen for enhancing the efficiency,and the intervention with Zuogui Pills + HRT exerts the highest probability of the optimal regimen for lowering the serum FSH level.However,due to the low quality of the included studies,more rigorously-designed,large sample-size,and high-quality randomized controlled trials need to be conducted in the future to provide conclusive evidence-based evidence.

OBJECTIVETo observe the effect of local injection of recombinant hirudin on survival of skin flaps with venous congestion in a rabbit model.

METHODSEighteen healthy rabbits were enrolled and divided into heparin-treatment (HT), recombinant hirudin treatment (RHT) and control (C) groups according to the random number table, with 6 rabbits in each group. After intravenous anesthesia with 20 g/L pentobarbital sodium, model of skin flaps with venous congestion in the size of 6 cm × 3 cm was reproduced in the dorsal side of left ear of each rabbit, in which central artery of ear served as the only blood supply, and a pedicle of 1 cm in width including central vessel of ear and its accompanying nerves as the only venous return pathway. Each flap in RHT, HT, C groups was respectively given 1 mL recombinant hirudin (1 U), low-molecular-weight heparin (625 U), and isotonic saline via multi-point and homogenous injection, then they were sutured in site. Appearance and survival rate of the flaps were observed after operation. Specimens of the distal part of flaps were harvested for determination of thromboxane B2 (TXB2) on post operation day (POD) 1, 3, 5, 7. Data were processed with one-way analysis of variance and t test.

RESULTSRabbit model of skin flaps with venous congestion was reproduced successfully. Obvious hair loss was observed in completely necrotic parts of flap in each group. Obvious edema was observed in all flaps with venous congestion at distal site. The color of flaps in HT and RHT groups were lighter as compared with that in C group, and apparent hematoma of flap was observed in 1 rabbit of RHT group, 2 rabbits of HT group, 4 rabbits of C group on POD 1. The survival rate of flap in HT and RHT groups was respectively (92.3 ± 1.7)% and (94.8 ± 1.9)%, both higher than that in C group [(77.9 ± 1.2)%, F = 191.29, P < 0.05]. There was no statistical difference in survival rate of flap between HT group and RHT group (t = 2.75,P > 0.05). The content of TXB2 in HT and RHT groups on POD 3, 5 was respectively lower than that in C group (with t value from 6.68 to 30.55, P values all below 0.01), but there was no statistical difference between HT and RHT groups (with t value respectively 1.22, 6.44, P values all above 0.05).

CONCLUSIONSLocal injection of low-molecular-weight heparin or recombinant hirudin can significantly ameliorate venous congestion of skin flap in rabbit ear, and improve its survival rate.
