To systematically evaluate the efficacy and safety of acupuncture versus Flunarizine hydrochloride in the treatment of migraine. Four Chinese databases(CNKI, VIP, WanFang, CBM), three English databases(Cochrane Library, EMbase, Medline) and ClinicalTrail.gov were systematically and comprehensively retrieved. The retrieval time was from the establishment of each database to January 8, 2020. Randomized controlled trial(RCT) for acupuncture versus Flunarizine in the treatment of migraine were screened out according to inclusion criteria and exclusion criteria. The included studies were evaluated with the Cochrane bias risk assessment tool. The included studies was conducted by RevMan 5.3, and the outcome indicators were evaluated for evidence quality and strength of recommendation by the GRADE system. A total of 1 033 literatures were retrieved, and 23 studies were finally included. Except for 4 multiarm tests, the total sample size was 1 548, including 785 in acupuncture group and 763 in Flunarizine group. The overall quality of the included studies was not high. Meta-analysis results showed that the acupuncture group was superior to the Flunarizine group in reduction of headache frequency(SMD=-1.00, 95%CI[-1.45,-0.54], P<0.000 1). In reduction of headache intensity, acupuncture group was superior to Flunarizine group(SMD=-1.05, 95%CI[-1.41,-0.68], P<0.000 01). In reduction of headache duration, acupuncture group was superior to Flunarizine group(SMD=-1.42, 95%CI[-1.83,-1.02], P<0.000 1). The acupuncture group was superior to Flunarizine group(MD=-0.17, 95%CI[-0.21,-0.13], P<0.000 01) in reduction of the painkillers taking frequency. The acupuncture group was superior to Flunarizine group(SMD=-0.94, 95%CI[-1.35,-0.52], P<0.000 1) in allevia-tion of paroxysmal symptoms, such as nausea and vomiting. The GRADE system showed that the evidence level of the above indicators was extremely low, and the strength of recommendation was low. As for the occurrence of adverse reactions, the adverse reactions reported in the acupuncture group included in the study were all mild adverse reactions, like drowsiness, subcutaneous bleeding, local pain, subcutaneous hematoma and dizziness needle. The available evidence showed that acupuncture has a better efficacy than Flunarizine hydrochloride in the treatment of migraine in adult patients. However, due to the high bias risk in the included studies, the conclusions of this study shall be adopted with caution, and more high-quality studies shall be carried out for verification in the future.

To evaluate the efficacy and safety of Yangxue Qingnao Granules alone or combined with calcium channel blocker in treatment of migraine. In this study, four Chinese databases(CNKI, VIP, WanFang, CBM), three English databases(Cochrane Library, EMbase, Medline) and clinical trials registration center(ClinicalTrials.gov) were retrieved. The retrieval time was from the establishment of each database to January 8, 2020. According to the set inclusion criteria and exclusion criteria,the randomized controlled trial(RCT) of Yangxue Qingnao Granules alone or combined with calcium channel blocker was selected. The "Cochrane bias risk assessment" tool was used to evaluate the quality of the included studies. RevMan 5.3 was used to conduct Meta-analysis of the included studies and grade system was used to evaluate the evidence quality of the outcome indicators. A total of 583 documents were retrieved and finally included in 23 studies, with a total sample size of 2 308 cases, 1 171 cases in the treatment group and 1 137 cases in the control group. The overall quality of the research included was not high. Meta-analysis showed that,(1)in terms of effective rate, Yangxue Qingnao Granules combined with calcium channel blocker was better than calcium channel blocker(RR=1.24, 95%CI[1.17, 1.32], P<0.000 01), and there was no significant difference between Yangxue Qingnao Granules and calcium channel blocker(RR=1.36, 95%CI[0.91, 2.03], P=0.14).(2)In terms of reducing headache frequency, when the unit of headache frequency was times per month, Yangxue Qingnao Granules combined with calcium channel blocker was better than calcium channel blocker(MD=-1.39, 95%CI[-1.83,-0.95], P<0.000 01), when the unit of headache frequency was times daily, Yangxue Qingnao Granules combined with calcium channel blocker was better than calcium channel blocker(MD=-2.08, 95%CI[-2.34,-1.82], P<0.000 01).(3)In terms of headache intensity, when headache intensity was scored by pain intensity, Yangxue Qingnao Granules combined with calcium channel blocker was better than calcium channel blocker(MD=-0.70, 95%CI[-0.81,-0.59], P<0.000 01), when headache intensity was scored by VAS score, Yangxue Qingnao Granules combined with calcium channel blocker was better than calcium channel blocker(MD=-1.59, 95%CI[-2.13,-1.06], P<0.000 01).(4)In terms of reducing headache duration, Yangxue Qingnao Granules combined with calcium channel blocker was better than calcium channel blocker(SMD=-3.13, 95%CI[-4.12,-2.15], P<0.000 01). GRADE system showed that the evidence level of the above outcome indicators was low and extremely low. Twelve cases of adverse reactions were reported, all of which were mild. The results showed that the combination of Yang-xue Qingnao Granules can improve the effective rate, reduce the headache frequency, the headache intensity and the headache duration, and had good safety and low incidence of adverse reactions compared with the single calcium channel blocker. However, there was no difference in the effective rate between Yangxue Qingnao Granules alone and calcium channel blocker. In view of the low quality of this study, which affects the reliability of the conclusion, it is necessary to use the conclusion of this study carefully, and more high-quality randomized controlled trials are needed to further verify in the future.

Objective To investigate localized regional recurrence after chemotherapy and chest radiotherapy in limited stage small cell lung cancer (LS-SCLC),and explore the relationship between recurrence location and radiotherapy and chemotherapy and its influencing factors.Methods From 2006 to 2014,pathological LS-SCLC treated in CAMS,125 patients had local recurrence,Kaplan-Meier statistical method was used to analyze the survival rate and PFS of each recurrence site.Log-rank was used to compare the survival rate of each group.Univariate analysis includes Chi-squareand t-test for the factors for the recurrence site.Multivariate analysis using Logistic regression.Results The 1-,2-and 5-year overall survival rates were 92.0％,46.4％ and 14.7％,respectively.The median progression time was 12.96 months,The median survival time after progression was 1 1.5 months,and the 1-,2-,and 5-year overall survival rates were 45.0％,23.0％,and 10.0％,respectively.The recurrence sites include intrapulmonary recurrence (67 patients),regional lymph nodes (21 patients),simultaneous intrapulmonary and regional lymph nodes (28 patients),and contralateral or supraclavicular lymph nodes (9 patients).The median survival time were 23.96 months,24.76 months,23.23 months,and 18.66 months,and the 2-year survival rates were 49％,52％,46％,and1 1％,respectively (P=0.000,0.004,0.008).In 6 patients (4.0％),5 patients were located in the supraclavicular region,and 1 patient (0.8％) in the field.Conclusions For LS-SCLC undergoing IMRT and chemotherapy,the local failure location is mainly located in the pulmonary,and further treatment of the split dose and targets requires further clinical exploration.

AIM To investigate the protective effects of Dahuang Zhechong (DHZC) Pills (Rhei Radix et Rhizoma,Eupolyphaga seu Steleophaga,Hirudo,etc.) against alcoholic liver fibrosis (ALF) injury in mice and to explore the underlying mechanisms.METHODS C57BL/6 male mice were used to build up ALF injury model,intervened with DHZC Pills.The serum of mice was examined for changes in alanine transaminase (ALT),aspartate aminotransferase (AST),interleukin-6 (IL-6),interleukin-10 (IL-10),interferon-γ (IFN-γ) and tumor necrosis factor-α (TNF-α).Simultaneously,the deposit of collagen 1 (COL-1) and apoptotic cell death in liver tissues were analyzed by immunofluorescent and TUNEL assay,respectively.The expressions of cleaved caspase-3 (CC3) in livers were measured by Western blot.RESULTS Compared with the model group,the levels of serum ALT,AST,IL-6,IFN-γand TNF-α of mice in DHZC group were decreased significantly.And the level of serum IL-10 of mice in DHZC group was increased significantly.Mice in DHZC group had higher rates of COL-1 deposition and apoptotic cell death in liver tissues than those in the model group.Mice treated with DHZC Pills showed lower expression of CC3.CONCLUSION DHZC Pills confers protection against ALF injury in mice by inhibiting the generation of COL-1 and down-regulating apoptosis of liver cells death as a result of adjusting the levels of inflammatory factors.

Objeetive As to the high incidence of arteriovenous fistula(AVF) stenosis,surgical operation will result in the exhaustion of vascular resources in patients,while percutaneous transluminal angioplasty(PTA) can maintain vascular resources for ostomy.However,there is still no clear definition between the choices of PTA and surgical resection.The aim of this study was to compare the efficacy of PTA and surgical resection followed by reconstruction for the treatment of arteriovenous fistula stenosis in order to find appropriate treatment.Methods Retrospective analysis had been done on 46 hemodialysis patients with arteriovenous fistula stenosis in Nanjing BenQ hospital from January 2015 to March 2017,which included 22 cases treated with PTA (PTA group) and 24 cases treated with surgical operation (operation group).Comparison was made in general clinical situation,patency rate at six months after surgery,over patency time and adverse reactions to surgery between the two groups.Results The number of stenoses in PTA group was bigger than that in operation group and the difference was of statistic significance (2.78±1.43 vs 1.67±0.71,P＜0.05).There was no significant difference in patency rate between the two groups (P =0.828).There were 57 venous stenoses in PTA group,among which 12 stenoses were anastomotic (21.05％) with 79.3％ average stenosis degree and 43 stenoses were at venous outflow tract of fistula (75.44％) with 84.26 average stenosis degree.In PTA group,3 patients had hematoma brachial puncture position and recovered by self-absorption without special treatment.In operation group,1 patient had mild blood oozing and recovered after treatment;4 patients recovered gradually from mild swelling on the back of the hand of the operation side.No difference was found in adverse reactions between two groups (P＞0.05).Conclusion PTA treatment is preferred for multiple stenoses(n ≥ 3),which ensures better preservation of vascular resources at a comparable patency rate.

Objective To evaluate the success rate,vascular patency time and their influencing factors of percutaneous transluminal angioplasty (PTA) in treating swollen hand syndrome in hemodialysis patients.Methods The clinical data of 16 hemodialysis patients with swollen hand syndrome,who were admitted to authors' hospital during the period from May 2015 to March 2017 to receive PTA,were retrospectively analyzed.The technical success rate,the follow-up primary vascular patency time and primary patency rate were calculated,and the factors influencing technical success rate and vascular patency time were analyzed.Results Venography with DSA revealed that a total of 16 segments of venous stenosis or occlusion were found in 16 patients,including 6 stenotic lesions and 10 occlusive lesions.Successful PTA was obtained in 14 patients,including one patient whose angiography performed immediately after PTA with balloon dilatation showed that the stenosis was still over 50％,and stent implantation had to be carried out.The technical success rate was 87.5％,in 2 patients PTA failed as the guide wire could not pass through the long segment of vascular occlusion.The 14 patients were followed up for 3-24 months,and the median patency time was 10.5 months.The 3-,6-and 12-month primary patency rates were 71.4％ (10/14),57.1％ (8/14) and 42.9％ (6/14) respectively.Univariate analysis indicated that the length of occlusive segment and the balloon pressure required for angioplasty were the potential factors that affected the postoperative vascular patency time.Conclusion For the treatment of swollen hand syndrome in hemodialysis patients,PTA is safe and effective,although long-term vascular patency rate needs to be further improved.

Objective To explore the ability and mechanism of insulin-like growth factor l (IGF-1) induced bone mesenchymal stem cells ( BMSCs) differentiation into cardiomyocyte-like cells ( CLCs).Methods BMSCs were isolated and purified in vitro.BMSCs were treated with control medium and 15 ng/ml IGF-I for 3,7, 14 and 21 d, respectively. The expression of Troponin-T ( TNT), Troponin-I (TNI) and pIGF-1R were c~etected by immunocytochemistry and Westem blot.In another experimental setting,BMSCs were treated with control medium and 15 ng/ml IGF-l,ICF-1 antaS;onist I-Ome AG538 (300 nmol/L) and 300 nmol/L I-Ome AG538 + 15 ng/ml IGF-1 for 3 t0 48 h,respectively.Phosphorylation status of ERKl/2 and AKT,the two downstream mediators of mitogen-activated protein kinase ( MAPK) kinase and phosphatidylinositol 3-kinase ( PBK) pathways,were detected by immunocytochemistry and Yvestem blot.Results After 3 t0 21 d exposrue to IGF-1, the expression of pIGF1R,TNT and TNI were significandy higher in 'IGF-1 group than those in control group,pIGF-IR peaked 14 d (all P ＜0.05).After 3 and 6 h treatment,the ratio of pAKT/AKT(0.17 ± 0.03)and pERK1/2/ERK1/2(0.06 ± 0.03)were significantly downregulated in I-Ome AG538 group compared to control group (1.00 ±0.05) (all P ＜ 0.05).The ratio of pAKT/AKT(1.00 ± 0.07) and pERK1/2/ERK1/2 (1.00 ± 0.09) were significantly upregulated in IGF-1 group compared to control group (0.72 ± 0.05) (all P ＜ 0.05),but the ratio of pAKT/AKT(0.31 ± 0.10)and pERK1/2/ERK1/2 (0.39 ±0.04) were significantly downregulated in I-Ome AG538 group compared to control group (0.63 ± 0.05) (all P ＜ 0.05),the value of gray scale of TNT (195.06 ± 5.98) and TNI (198.32 ± 3.46) in I-Ome AG538 + IGF-1 group were significantly upregnlated than that in IGF-1 group for TNT (188.70 ± 5.35) and TNI (176.10 ± 4.96) (all P ＜ 0.05).Conclusions IGF-1 could induce BMSCs differentiation into CLCs in vitro by activating MAPK and PI3K signaling pathways.

Objective To investigate the role of antigen-processing machinery (APM) component defects in HLA class Ⅰ antigen down-regulation in laryngeal squamous cell carcinoma (SCC) and to assess the clinical significance of these defects. Methods Fifty-one formalin-fixed,paraffin-embedded SCC specimens were examined for the expressions of APM component transporter associated with antigen processing (TAP1) and low molecular weight polypeptide (LMP-7) and HLA class Ⅰ antigen by immunohistochemistry.Results HLA class Ⅰ antigens,TAP-1 and LMP-7 expressions were downregulated in 56.9％ (29/51),39.2 ％ (20/51) and 45.1％ (23/51) of the tested specimens respectively,whereas HLA class Ⅰ antigens,TAP-1 and LMP-7 expressions lost in 21.6 ％ ( 11/51 ),33.3％ ( 17/51 )and 27.5 ％ ( 14/51 ) of the tested specimens respectively.TAP-1 and LMP-7 expressions were significantly correlated with HLA class Ⅰ antigen expression (r =0.460,P < 0.05 and r =0.685,P < 0.05,respectively).HLA class Ⅰ antigens down-regulation was significantly correlated with T stage( x2 =8.61,P ＜ 0.05).Both TAP-1 and LMP-7 down-regulations were significantly correlated with T stage ( x2 valueswere 9.72 and 8.97 respectively,P ＜ 0.05 ) and TNM stage( x2 values were 9.18 and 7.70 respectively,P ＜0.05 ).TAP-1,LMP-7 and HLA class Ⅰ antigen down-regulations were significantly associated with reduced patients' overall survival ( P ＜ 0.05 ) and disease-free survival ( P ＜ 0.05 ).Multivariate analysis showed lymph node metastasis,recurrence and HLA class I antigen down-regulation were unfavorable prognostic factors(P ＜ 0.05).Conclusions Down-regulated expressions of HLA class Ⅰ antigen and APM component TAP-1 and LMP-7 occur frequently in laryngeal squamouss cell carcinoma,by which cancer cells could avoid immune surveillance,while HLA class Ⅰ antigen down-regulation is a major contributing factor to tumour progression and mortality.

Objective To investigate the oncolytic effect of E1B mutant adenovirus (d11520) on human malignant gliomas. Methods Ad-βgal vector was used to investigate the infectibility of dl1520.U251,Hep3B (positive control) and T24 (negative control) cell lines were infected with dl1520respectively at 50,5,0.5,0.005 and 0 pfu of multiplicity of infection (MOI).The replication efficiency of d11520 in host cells was assessed by plaque assay.The cytopathic effect (CPE) was assessed by crystal violet staining in a panel of tumor cells. Results Crystal violet staining showed the Hep3B cell line was the most sensitive to dl1520 and had the fastest CPE,followed by the U251 cell line,while the T24cell line had no CEP.The replication and infection rates ofdl1520 in the U251 cell line were lower than in the Hep3B cell line but significantly higher than in the T24 cell line (P＜0.05). Conclusion The E1B mutant adenovirus (dl1520) has a significant oncolytic effect on human malignant gliomas.
