Objective:To observe the clinical efficacy of warm needling plus acupoint sticking therapy for primary dysmenorrhea.
Methods:A total of 60 eligible cases were randomly allocated into a treatment group (n=30) and a control group (n=30) according to their sequence of consultation. Patients in the treatment group were treated with warm needling combined with acupoint sticking therapy, whereas patients in the control group were treated with oral Ibuprofen (Fenbid) capsules. After two menstrual cycles, the visual analogue scale (VAS) score, COX menstrual symptom scale (CMSS) and clinical efficacy were compared between the two groups.
Results:After treatment, the VAS and CMSS scores were significantly reduced in both groups, indicating that both treatment protocols can remarkably alleviate pain. There was a between-group statistical difference in comparing the CMSS score (P<0.05), but no between-group statistical difference in the VAS score (P>0.05). However, the follow-up visit showed between-group statistical differences in comparing VOA and CMSS scores (bothP<0.01). The clinical effect, relapse rate and long-term efficacy in the treatment group were better than those in the control group.
Conclusion:Warm needling plus acupoint sticking therapy is a simple but effective therapy for primary dysmenorrhea. In addition, it causes fewer cases with relapse.

Objective To evaluate the efficacy and safety of intra-arterial thrombolysis with recombinant tissue-plasminogen ac-tivator(rt-RA) for treatment of acute cerebral infarction (ACI) .Methods The randomized controlled trials (RCT ) of intra-arterial thrombolysis with rt-PA for treatment of ACI were selected from Cochrane Library ,Medline ,Embase and CBM by the computer re-trieval .A meta analysis of the data were analyzed by using RevMan 5 .1 software .Results A total of 473 patients in 9 selected RCTs were involved in the systematic review .Meta-analysis results disclosed suggested that the effectiveness of intra-arterial thrombolysis treated ACI group was better than that of intravenous thrombolysis group [RR= 1 .26 ,95% CI(1 .09 ,1 .45) ,P=0 .002] .No difference was observed between the two groups in intracranial hemorrhage and mortality rate .Conclusion The current evidence showed that ,the clinical effect of intra-arterial thrombolysis with rt-PA for treatment of ACI was obviously superior to that of intravenous thrombolysis ,but the result still needs to be confirmed by large-sample RCTs .

Objective To analyze the clinical techniques of renal artery control in laparoscopic donor nephrectomy.Methods 211 relative living renal transplantations were performed from June 2003 to June 2012,and 136 donors underwent laparoscopic donor living nephrectomy (LDN) since 2007.Forty donors were subjected to the Hem-o-lock clips for renal artery control by open surgery,87 donors to the Hem-o-lock clips for renal artery control by laparoscope,5 donors to the Endo GIA stapler for renal artery control by laparoscope,and 4 donors to the Hem-o-lock clips by laparoscope combined with hand-assisted suture transfixion for renal artery control.Results The warm ischemia time of renal artery control was shortest (1.1 ± 0.3 min) by Hem-o-lock clips in open surgery,and longest (3.2 ± 0.8) min by the Hem-o-lock clips with laparoscope.There was significant difference in the warm ischemia time of renal artery between open group and other groups,the differences (P＜0.05).The comparison of prognostic factors in the transplant renal outcome showed no significant difference among groups.The renal arterial stump-rrhexis-caused massive secondary bleeding occurred in 1 case subject to Hem-o-lock clips for renal artery control by laparoscope,with conversion to open surgery urgently,the operation was successful at last.Other renal artery control ways were all safe without any adverse reaction.Conclusion The warm ischemia time of renal artery control by Hem-o-lock clips in open surgery was shortest in laparoscopic donor nephrectomy.The renal artery control way by Endo GIA stapler in laparoscope or by Hem-o-lock clips with hand-assisted suture transfixion is safest.The utilization of Hem-o-lock clips should be careful in high risk population such as severe atherosclerosis etc.

Objective To determine the expression of membrane-bound B lymphocyte stimulator (BLyS) protein and its mRNA in vitro of peripheral blood mononuclear cells (PBMCs) from individuals with systemic lupus erythematosus (SLE),and to investigate the role of interferon-?(IFN-?) on the expression of BLyS.Methods PBMCs were obtained from 25 SLE patients (mean age of 31+14) and 20 healthy volunteers (mean age of 28?10).They were randomized into IFN-?(5 ng/ml) group and control group.PBMCs were col- lected at 0,6,12 and 24 h for BLyS mRNA assessment using semi-quantitative reverse transcription-PCR (RT-PCR).PBMCs were also collected at 72 h for membrane-bound BLyS protein detection using flow cy- tometry (FACS) and direct immunofluorescence.Results①The expression of BLyS mRNA and membrane- bound protein in PBMCs was significantly higher in individuals with SLE compared with healthy controls (P＜0.05);②IFN-?enhanced BLyS mRNA expression in PBMCs in both healthy controls and SLE patients,with the greatest effect at 6 h (stimulated vs unstimulated,0.42?0.19 vs 0.25?0.14,P＜0.01;0.59?0.28 vs 0.44?0.21,P＜0.01 );③IFN-?also increased the expression of membrane-bound BLyS protein in both healthy con- trols and individuals with SLE (FACs,mean fluorescence intensity,4.5+3.0 vs 3.7~2.6,P

Objective To investigate the effects of different extracts of pericarpium citri reticulatae (PCR) and pogostemon cablin benth (PCB) on the contraction of gastrointestinal smooth muscle and the level of gastrointestinal hormones in rat model of gastrointestinal motility disorder. Methods Seventy Wistar rats were randomly divided into groups of control, model, water extractive of PCR, hesperidin, water extractive of PCB, water extractive of PCB plus volatile oil and patchouli alcohol, ten rats in each group. Except the control group, the rest groups were established gastrointestinal motor disorder model via limb ischemia-reperfusion (LIR). After modeling rats of groups were intervened with corresponding extracts. The effects of different extracts on contraction amplitude of corpora ventriculi and small intestine smooth muscle were observed. The levels of gastrointestinal hormones including motilin (MOT), gastrin (GAS), cholecystokinin (CCK) and somatostatin (SS) were detected by radioimmunoassay. Results The contraction amplitudes of corpora ventriculi and small intestine smooth muscle were decreased (P<0.05), the serum level of GAS and plasma level of MOT were also significantly decreased, while CCK and SS levels in the gastric antrum were significantly increased in model group than those of the control group (P < 0.05). Water extractive of PCR, hesperidin, water extractive of PCB and water extractive of PCB +patchouli oil can increase the contraction amplitudes of corpora ventriculi and small intestine smooth muscle, increase the serum level of GAS and reduce levels of CCK and SS in the gastric antrum (P<0.05), whereas showed no influence in the plasma level of MOT (P>0.05)]. Compared with model group, patchouli alcohol showed no influence in the contraction of gastrointestinal smooth muscle and levels of MOT, GAS, CCK and SS (P>0.05). In the aspect of regulating the contraction of gastrointestinal smooth muscle and the level of GAS, CCK and SS, the pharmacological effect of PCR water extract was better than that of hesperidin (P<0.05), while water extractive of PCB+volatile oil was better than that of water extractive of PCB (P < 0.05). Conclusion The active ingredients of PCR and PCB have variant regulative effects on the contraction of gastrointestinal smooth muscle and the serum level of GAS, CCK and SS in the gastric antrum in rat model of gastrointestinal motility disorder.

OBJECTIVETo investigate that the role of Axin in regulating the invasion and migration ability of lymphoma cells and explore the molecular mechanisms.

METHODSThe expressions of Axin, β-catenin, MMP7, and MMP9 were detected in different lymphoma cell lines by RT-PCR and Western blotting. A lymphoma cell line with low Axin expressions was transiently transfected with pCMV5-HA-Axin and pcDNA5-His-β-catenin plasmid, and the expressions of β-catenin, MMP7, and MMP9 mRNA and protein were observed. A lymphoma cell model stably overexpressing Axin was transfected with AXIN-shRNA and β-catenin-shRNA, and the changes in β-catenin, MMP7, and MMP9 cexpressions were observed. The changes in the invasion and migration abilities of this cell model were assessed following Axin knockdown.

RESULTSIn the lymphoma cell lines tested, the Axin expression showed a negative correlation with β-catenin, MMP7, and MMP9 expressions. In Raji cells with a low Axin expression, overexpression of Axin resulted in decreased expressions of β-catenin, MMP7, and MMP9 at the protein levels but not the mRNA levels, and overexpression of β-catenin obviously increased MMP7 and MMP9 mRNA and protein expressions. In the cells with stable Axin overexpression, Axin knockdown caused increased expressions of β-catenin, MMP7, and MMP9 at the protein levels but not the mRNA levels, while β-catenin knockdown caused lowered expressions of MMP7 and MMP9 and suppressed cell invasion and migration.

CONCLUSIONIn lymphoma cells, Axin overexpression can decrease the expression of β-catenin, which in turn decreases the expressions of MMP7 and MMP9 to inhibit the cell invasion and migration.

OBJECTIVETo study the characteristics of the virology background of HLA-A2 restricted HBcAg(18-27) epitope mutations in HBV infected patients in China.

METHOD30 HBV sequences with different genotypes from Genbank were analyzed by bioinformatics and the mismatched primers were designed for constructing a PCR-RFLP method to screen HBcAg(18-27)V/I in China. The distributions of HBcAg(18-27)V/I of 160 samples with HBV genotype B/C infection from 8 areas in China were screened and analyzed by PCR-RFLP and sequencing. The affinity of HBcAg(18-27)V/I to HLA-A0201 was analyzed through referencing the bioinformatics websites.

RESULTSWe successfully constructed a PCR-RFLP method for screening HBcAg(18-27)V/I from genotype B/C, and only 3 samples with HBcAg(18-27)V sequence were found in the 160 samples (3/160, 1.88%). The affinity of HBcAg(18-27)I to HLA-A 0201 was lower than the one of HBcAg(18-27)V through bioinformatic analysis (HLA ligand score was 123 vs 156, and the SYFPEITHI score was 22 vs 24).

CONCLUSIONThe last amino acid of most HBcAg(18-27) sequences of epidemic HBV strains in China is isoleucine, and not valine. Therefore HBcAg(18-27) sequence background in different HBV genotypes should be thoroughly considered when using it as a reference or control in immunological research about HBV.

Objective To evaluate the efficacy and safety of high-frequency repetitive transcranial magnetic stimulation (rTMS) in the treatment of post-stroke depression (PSiD).Methods The Cochrane Library,Medline,EMbase and CBMdisc were electronically searched for reports of randomized and controlled trials (RCTs) of high-frequency rTMS in the treatment of PSD before October 2017.Two researchers screened the reports independently,extracted data and assessed the risk of bias in the included studies.The meta-analysis was performed using version 5.1 of the RevMan software.Results A total of 26 RCTs were included,covering 1810 patients with PSD.The metaanalysis showed that the remission rate [relative risk (RR) =2.15,95％CI (1.64,2.83)] and the effectiveness [RR =1.66,95％CI (1.28,2.15)] of high-frequency rTMS group were significantly higher than in the control groups.Compared with the control group,the average Hamilton depression rating scale (HAMD) score of the high-frequency rTMS groups was significantly lower than in the control groups.There was no significant difference in withdrawal between the two groups after treatment [RR =0.55,95％CI (0.18,1.65)].The incidence of headaches was significantly higher in the high-frequency rTMS group than among the controls.Conclusion High-frequency rTMS has a good curative effect and better acceptability for PSD patients,but attention should be given to headaches and other adverse reactions.Due to the limited number of studies and their quality,these conclusions still need to be verified in betterquality studies.

OBJECTIVETo explore the relationship between heavy metals exposure and neurobehavioral function impairment in welders.

METHODSThe metals exposure in 82 welders and 51 operators were investigated with blood Pb, Cd and Mn via AAS, and the nervous impairment was evaluated with neurobehavioral core test battery (NCTB).

RESULTSPb [(115.49 +/- 79.22) microg/L] and Cd [(3.67 +/- 3.19) microg/L] in welders were significantly higher than operators [(69.32 +/- 50.79) and (0.83 +/- 0.76) microg/L respectively] (P < 0.05). Welders had worse standard scores of NCTB 13 items such as depression-dejection than non-welders (P < 0.05). Significant difference of confusion-bewilderment and forward digit span in welders only existed in different groups of Pb and Mn, respectively. A dose-effect relationship was found between forward digit span and serum Mn level in welders. General linear regression analysis indicated that Pb exposure, Mn exposure and alcohol consume had negative relation with the loss of nervous system function.

CONCLUSIONThe nervous impairment in welders is attributed to occupational exposure to Pb and Mn, concomitantly.
