Objective: To observe the clinical effects of acupoint injection therapy plus massage on primary dysmenorrhea (PD).
Methods: Ninety patients with PD were randomly divided into a treatment group or a control group, 45 cases in each group. The treatment group was treated by injection of Vitamin K3into Sanyinjiao (SP 6) plus massage on Diji (SP 8). The control group was treated by oral administration of Ibuprofen sustained-release capsule. Before and after the treatment, visual analogue scale (VAS) was adopted to assess pain degree of the patients. The therapeutic effects were observed after continuous treatment of three cycles of menstruation.
Results: After treatment, VAS scores were obviously decreased in both groups and the differences were statistically significant (allP<0.05). The difference in VAS score after treatment was more significantin the treatment group than that in the control group (P<0.01). The total effective rate was significantl higher in the treatment group than that in the control group (P<0.05).
Conclusion: Acupoint injection therapy plus massage for PD is effective and better than simple oral administration of Ibuprofen sustained-release capsule.

Objective To compare the effectiveness and safety of radiofrenquency ablation(RFA) with other therapeutic methods for patients with early hepatocelluar carcinoma(HCC). Methods Randomized clinical trials(RCTs)which compared the efficacy or safety of RFA with other therapeutic methods for primary hepatocellular carcinoma in Cochrane library,EMBASE,PubMed,OVID and CBM were searched.Trials were considered of high quality if methodological quality score was 3 or more according to Jadad standard.Statistical heterogeneity between trials was evaluated bv STATA 9.0 and considered to exist when P＜0.1.Heterogeneity of the included articles was tested and used to select proper effective model for calculation.Sensitivity analysis was performed and publication bias was investigated through visual inspection of funnel plots and Egger regression model.Results Six RCTs including 862 cases were analyzed.As compared with other therapeutic approaches,RFA significandy increased 3-year overall survival rate and reduced local recurrence rate of early hepatocelluar carcinoma:the total OR were 2.06(95%CI being 1.54-2.77,P=0.000)and 0.40(95%CI being 0.28-0.57,P=0.000)respectively.As compared with other therapeutic approaches,the total OR of new HCC recurrence rates,extrahepatic metastasis rate and major complications in patients with HCC treated with RFA were 0.92 (95%CI being 0.68-1.24),0.98(95%CI being 0.30-3.22),1.35(95%CI being 0.49-3.77)respectively,showing no significant differences(P＞0.05).Inspection of the funnel plots for all outcome measures did not reveal evidence of publication bias(P=0.670,0.160,0.884,0.087,0.317,respectively,by Egger regression model).Conclusions RFA is superior to other treatment methods with respect to local recurrence and 3 year overall survival in early HCC and is the preferred tberapeutic method for small HCC because it is minimally invasive,simple and convenient.

OBJECTIVE: To investigate effects of polysulphone membrane filter continuous blood purification (CBP) on decreasing pancreatic amylase and various inflammatory mediators in the treatment of severe acute pancreatitis.METHODS: A total of 47 elderly patients with severe acute pancreatitis, who received CBP therapy was included in the experiment, and the blood routine test, blood biochemistry indexes and blood-gas analysis were performed prior to CBP therapy and continuous for 12 and 24 hours. Meanwhile, APACHE Ⅱ, SAPS Ⅱ and MODS scores were graded by recorded the heart rate, mean arterial pressure (MAP), central venous pressure (CVP), respiratory frequency and body temperature.RESULTS: Compared with pre-treatment, APACHE Ⅱ, SAPS Ⅱ and MODS scores, serum creatinine, hemodiastase, as well as C-reactive protein were decreased after treatment. After treatment, the oxygen index, such as heart rate, MAP, and CVP were declined, and the levels were increased progressively with time prolonged. During the course of CBP, the levels of HCO_3~-, Ga~(2+),and Mg~(2+) were increased than that of pre-treatment. The level of Ga~(2+), Mg~(2+) could maintain in a normal range during CBP therapy, however, it would be decreased when stop treatment.CONCLUSION: The improvement of cardio-pulmonary function relates to interstitial edema of tissue and organs. The effect on removing pancreatic amylase and various inflammatory mediators will be better with time prolonged. It is affirmative to treat elderly patients with severe acute pancreatitis by using CBP therapy.

Objective To investigate the application of laparoscope,duodenoscope and choledochoscope in the treatment of intra-and extrahepatic bile duct stone.Methods The clinical data of 3 16 patients with intraand extrahepatic bile duct stone who were admitted to the Bethune First Hospital from April 2007 to August 2010were retrospectively analyzed.There were 269 patients with cholecystolithiasis and choledocholithiasis,10 patients with cholesystolithiasis,choledocholithiasis and hepatolithiagis,and 37 patients with choledocholithiasis.Laparoscopic cholecystectomy(LC)+laparoscopic common bile duct exploration(LCBDE)+choledochoscopy was applied to patients with hepatolithiasis or with the diameter of common bile duct≥10 mm;endoscopic sphincterotomy (EST)+LC or LC+EST was applied to patients with the diameter of common bile duct between 10 mm and 5 mm and the diameter of cystic duct<5 mm;LC+laparoscopic transcystic common bile duct exploration(TC-CBDE)+choledochoscopy wag applied to patients with the diameter of common bile duct≤5 mm and the diameter of cystic duct≥5 mm.Results The success rate of operation was 96.8%(306/316).A total of 163 patients received LC +LCBDE+T-tube drainage+choledochoscopy,and the mean operation time,expense,duration of hospital stay were 93.6 minutes,2.8×104 yuan and 9.8 days,respectively,and 5 patients had complications postoperatively.Fifty-four patients received EST+LC,and the mean operation time,expense,duration of hospital stay were 45.0minutes,6.6 days,2.3×104yuan,respectively,and 1 patient had complication postoperatively.Sixty-seven patients received LC+EST,and the mean operation time,expense and duration of hospital stay were 40.0minutes,6.1 days,2.4×104 yuan,respectively,and 2 patients had complication postoperatively.Thirty-two patients received one-stage repair of common bile duct and LC+TC-CBDE+choledochoscopy,and the mean operation time,expense and duration of hospital stay were 97.3 minutes,7.3 days and 2.5×104yuan,respectively,and 1 patient had complication postoperatively.A total of 272 patients were followed up for 12 months,except for 6 patients with recurrence of common bile duct stone,no residual stone or biliary stricture was etected.Conclusion Combined application of laparoscope,duodenoscope and choledochoscope has advantages of less trauma,quick ecovery and fewer complications in the treatment of intra-and extrahepatic bile duct stone.

MicroRNAs (miRs) play an important role in regulating diverse cellular processes.It has been reported that miRs are associated with the formation and maturation of erythrocytes, and the expression of globin genes at post-transcriptional level.Compared with normal human enrythrocytes, various miRs are altered in the patients with thalassemia.These changes also happen in the patients with diverse clinical manifestations.In this paper, we systematically summarized the recent progress about the expression dysregulation of miRs in β-thalassemia and their roles in regulating the levels of γ-globin and fetal hemoglobin.During β-like globin gene expression, miRs directly or indirectly regulate the levels of erythroid-specific transcription factors through post-transcriptional action, such as B-cell lymphoma 11A (BCL11A), myeloblastosis oncogene (MYB), specificity protein 1 (Sp1), Kruppel-like factor 3 (KLF3) and GATA1.These effects subsequently regulate the switch between γ-and β-globin gene expression and affect fetal hemoglobin production.Targeting miRs might be a novel therapeutic strategy for β-thalassmeia.

Objective To evaluate the effect of remifentanil on cell apoptosis during renal ischemia-reperfusion (I/R) in rats.Methods Seventy-five male Sprague-Dawley rats,weighing 220-250 g,were randomly divided into 3 groups (n =25 each):sham operation group (group S),I/R group,and remifentanil group (group R).Renal ischemia was induced by occlusion of the bilateral renal arteries for 45 min followed by reperfusion in groups I/R and R.Remifentanil was infused at 1.0 μg· kg-1 · min-1 via the caudal vein starting from 15 min before ischemia until 30 min of reperfusion in group R,while the equal volume of normal saline was given instead of remifentanil in groups S and I/R.At 15 min before ischemia (T0) and 3,6,12,24 h of reperfusion (T1-4),5rats were anesthetized and sacrificed,and renal specimens were obtained to detect the apoptotic rate and expression of Bax and Bcl-2 protein (by flow cytometry) and mRNA (by RT-PCR).The ratios between Bcl-2/Bax protein and mRNA expression were calculated.The pathological changes of renal tubules were scored.Results Compared with group S,the pathological scores and apoptotic rate were significantly increased at T1-4,and ratios between Bcl-2/Bax protein and mRNA expression were increased at T1,2,while decreased at T3,4 in groups R and I/R (P ＜0.01).Compared with group I/R,the pathological scores and apoptotic rate were significantly decreased at T1-4,while the ratios between Bcl-2/Bax protein and mRNA expression were increased in group R (P ＜ 0.05 or 0.01).Compared with the baseline value at T0,the pathological scores and apoptotic rates were significantly increased at T1 4,and the ratios of Bcl-2/Bax protein and mRNA expression were increased at T1,2,while decreased at T3,4 in groups R and I/R (P ＜ 0.01).Conclusion Regulation of Bcl-2/Bax expression and inhibition of cell apoptosis in renal tissues are involved in the mechanism by which remifentanil reduces renal I/R injury in rats.

The efficacy of standard triple therapy for Helicobacter pylori (Hp) eradication has been significantly decreased, or even less than 80%.Abroad studies have shown that Hp eradication rate of sequential therapy is significantly higher than that of triple therapy.At home, we lack a large sample of data analysis to clarify the efficacy of sequential therapy.Aims: To systematically review the efficacy of sequential therapy and triple therapy in Hp eradication at home and abroad.Methods: PubMed, Medline, Embase, Cochrane Library, CNKI, Wanfang, VIP and CBMdisc were retrieved to collect the randomized controlled trials (RCT) comparing sequential therapy and triple therapy in the treatment of Hp infection in last 7 years.Article selection, data extraction and quality evaluation were conducted independently by two reviewers.Meta-analysis was conducted by RevMan 5.3 software.Results: A total of 31 RCT involving 8 371 subjects were included.Meta-analysis showed that Hp eradication rate of sequential therapy was significantly higher than that of triple therapy (83.3% vs.74.7%;RR=1.13, 95% CI: 1.09-1.16).Sixteen domestic studies showed that Hp eradication rate of sequential therapy was significantly higher than that of triple therapy (88.1% vs.78.0%;RR=1.13, 95% CI: 1.10-1.16), fifteen abroad studies showed that Hp eradication rate of sequential therapy was significantly higher than that of triple therapy (79.0% vs.71.8%;RR=1.13, 95% CI: 1.06-1.20).No significant difference in incidence of adverse reactions was found between sequential therapy and triple therapy (20.7% vs.22.0%;RR=0.94, 95% CI: 0.86-1.03).Conclusions: Sequential therapy achieves higher Hp eradication rate than standard triple therapy, and no significant difference in incidence of adverse reactions is found between sequential therapy and triple therapy.Hp eradication rate of sequential therapy is significantly higher than that of triple therapy and is higher than 80% in China, which can be recommended as a Hp eradication supplement of bismuth quadruple therapy.

Objective To investigate the effects of different fine particulate matter (PM2.5) components (water-soluble, organic, water-soluble+organic) in vivo on the NOS/NO system in the endothelial cells from rat thoracic aortas. Methods Three PM2.5 components were used to inject by vein in rat tail. ELISA and immunohistochemical technique were used to examine the change of NOS/NO system in the blood-serum and the endothelial cells from rat thoracic aorta. Results Compared with control group, three PM2.5 components increased NO level of rat blood-serum [control, (38.00±5.40) μmol/L; water-soluble group, (44.66±16.59) μmol/L, t =3.58, P< 0.05; organic groups, (58.28±12.30) μmol/L, t =12.85, P <0.01; mixtural component group, (84.02+19.24) μmol/L, t =31.39, P<0.01]; increased iNOS level of rat blood-serum [control, (17.47±5.33) U/ml; water-soluble group, (21.87±4.63) U/ml, t =4.92, P <0.05; organic groups, (25.27±6.58) U/ml, t = 6.22, P<0.05; Mixtural component group, (32.79±5.86) U/ml, t =32.84, P <0.01]. Mixtural component decreased eNOS level of rat blood-serum [(12.58±4.59) pg/ml vs (17.47±2.97) pg/ml, t =5.91, P <0.05], no significant difference on eNOS level of blood-serum among other component groups (P >0.05). Three components decreased the expression of eNOS protein in the endothelial cells from rat thoracic aorta(control, 164.68±4.80; water-soluble group, 185.43±5.63, t =4.26, P <0.05; organic groups, 194.07±9.77, t =5.26, P <0.05; Mixtural component group, 209.24±15.43, t =43.19, P <0.01), increased the expression of iNOS protein (control, 160.17±5.79; water-soluble group, 134.78±8.22, t =5.21, P <0.05; organic groups, 134.78±8.22, t =5.98, P <0.05; Mixtural component group, 81.62 ±10.59, t =34.98, P <0.01) in the endothelial cells from rat thoracic aortas.Conclusion Three components of PM2.5 induced the dysfunction of endothelial cells and disorder of NOS/NO system in the endothelial cells.
