Methods By searching Cochrane Library, OVID, PubMed, Chinese biomedical literature service system(CBM),China National Knowledge Infrastructure(CNKI), VIP database(VIP), Wanfang database, the randomized controlled trials (RCTs),controlled clinical trials (CCT) and historical cohort study(HCT) of TR Band hemostasis after coronary artery intervention were collected and analyzed. Two reviewers used bias risk assessment tool according to Cochrane recommendation Handbook 5.0 to evaluate, Meta-analysis was carried out using RevMan 5.1.5 software. Results A total of 1 881 patients in 2 RCTs and 3 CCTs were included.Compared with the first decompression time 30 min, patients in 1 h group with limb swelling and pain incidence were statistically significant difference [ (OR=2.22, 95%CI 1.25-3.93, P<0.01) vs. (OR=1.63,95%CI 1.02-2.59, P < 0.05)], bleeding at the puncture sites or the operative limbnumbness or ecchymosis there was no significant difference [(OR=0.77,95%CI 0.35-1.71, P>0.05) vs.(OR=2.14, 95%CI 0.75-6.12, P>0.05)vs.(OR=11.73, 95%CI 0.64-215.74, P>0.05)];1h compared with 2 h patients with limbs, pain, hemorrhage rate had significant difference [(OR=0.09, 95%CI-0.13--0.05, P<0.01) vs. (OR=2.07, 95%CI 1.24-3.46, P<0.01)]; a comparison between 90 min and 2h, the limb pain and swelling incidence were statistically significant difference [(OR=2.77, 95%CI 1.82-4.23, P<0.01)vs.(OR=2.73,95%CI 1.41-5.28, P<0.01)], the puncture site bleeding, hematoma, ecchymosis rate and the operative limb numbness extent differences were no statistical significance [(OR=0.97,95%CI 0.61-1.54, P>0.05) vs. (OR=0.95, 95%CI 0.52-1.75, P>0.05)vs. (OR=0.96,95%CI 0.54-1.73, P>0.05)]. Conclusions 30 min decompression after TRI can reduce operative limb swelling and pain incidence rate. There is no obvious influence between puncture site bleeding and operative limb numbness.

Objective To evaluate the effectiveness of TR Band hemostat in trans-radial coronary intervention patients.Methods The randomized controlled trials (RCTs) on the application of TR Band hemostat in trans-radial coronary intervention patients were collected through the databases such as the Cochrane Library,OVID,PubMed,CBM,VIP and Wanfang Data.The quality of studies was critically appraised and data were extracted by two reviewers independently,and Meta-analysis was conducted for the included studies.Results Five RCTs involving 5 028 patients were included.Meta-analysis showed that the application of TR Band hemostat in trans-radial coronary intervention patients could shorten the time of hemostasis by compression,reduce the incidence rate of skin lesions,improve the postoperative patients with comfort,but the efficacy was not significant in puncture site bleeding,hematoma and incidence of radial artery occlusion (RAO).Conclusions The application of TR Band hemostat in trans-radial coronary intervention patients can significantly decrease the incidence of oppression hemostasis time and reduce the incidence rate of skin lesions,improve the postoperative patients with comfort.It is worth being popularized.

Purpose To assess the effect of pelvicfloor electrical stimulation treatment by transperineal sonography, so as to provide guidance for postpartum pelvic floor rehabilitation.Materials and Methods Thirty-one delivery women who received postpartum pelvicfloor rehabilitation were selected as research group and 30 non-pregnant young women as control group in the study. Pelvicfloor electromyography treatment was taken in research group, and transperineal sonography was undergone in quiet state and pressure state (Valsalva operation) before treatment, after the fifth treatment and after the tenth treatment respectively to measure the bladder neck to the public symphysis edge distance (Dr, Ds), bladder neck angle (θr,θs) and bladder rotation angle (θ). A comparison was made between the research group and control group.Results①Dr and Ds in research group were both lower than those in control group (P<0.05), butθr,θs andθ were all higher than those in control group (P<0.05).②Dr and Ds showed a gradual increase (P<0.05) whilstθr presented a gradual decrease before the treatment, after the fifth treatment and after the tenth treatment (P<0.05).Conclusion Natural childbirth may damage the function of pelvicfloor; electrical stimulation of pelvic therapy is effective on postpartum pelvicfloor rehabilitation; and transperineal sonography can objectively assess the effect of this therapy.

Objective To study the role of low-dose glucocorticoids in improving prognosis and adjusting septic shock. Methods A total of 46 patients with a confirmed diagnosis of septic shock were retrospaetivley analyzed. 24 patients without glucocorticoids treatment were taken as control group; 22 patients with glucocorticoids as therapy group (n = 22). The two group received standard treatment for septic shock. Results The percentage of shock reversal on day 7 was higher in therapy group than that in control group (P <0.05). However,there were notstatistical significances in the duration of mechanical ventilation, the length of ICU stay, the incidence of multiple or-gan dysfunction syndrome (MODS) and mortality between the two groups (P > 0.05). Conclusion Low-dose glucocorticoids can effectively accelerate refractory septic shock reversal and vasopreasor withdrawal. This seems to be related to the reduced production of CRP but the beneficial effects of low-dose steroids regimens on long-term outcome have not yet be determined.

Objective To observe the effect of Guanxinning Tablet (GXNT) on myocardial infarction and cardiac autonomic nervous function in rats with myocardial ischemia reperfusion injury (MI/RI).Methods Seventy SD rats were divided into 7 groups randomly (n=10);the sham group, the MI/RI group, 75 mg/kg, 150 mg/kg, 300 mg/kg and 600 mg/kg GXNT groups and 300 mg/kg Compound Danshen Tablets (DST) group.All rats were administered orally for 7 days, and then the MI/RI model was made by ligating the left anterior descending branch of coronary artery in rats.The changes of electrocardiogram were recorded and the electrocardiogram of J points and heart rate variability (HRV) parameters were analyzed.At the end of reperfusion, the myocardial infarct size was measured by using Evans blue and tetrazolium chloride (TTC) double staining, and pathological changes of myocardium were observed by HE staining.The changes of serum lactate dehydrogenase (LDH), creatine kinase (CK), malondialdehyde (MDA) and nitric oxide (NO) levels were also detected.Results Compared with MI/RI group, GXNT and DST groups were significantly reduced myocardial infarct size and inhibited the rising of serum LDH and CK activities (P < 0.05, P < 0.01), and also reduced the total or average value of J point during reperfusion (P < 0.05, P < 0.01).Meanwhile, GXNT and DST groups were markedly increased HRV and serum NO level as well as decreased serum MDA content (P < 0.05, P < 0.01), and improved myocardial tissue pathology.Conclusions GXNT can reduce the myocardial infarction in rats with MI/RI, and also improve the cardiac autonomic nervous function.

Conclusions Interferon atomization combined with mouth nursing can treat hand-foot-and-mouth disease effectively.

OBJECTIVETo establish an efficient and stable method for protein extraction of Streptococcus mutans.

METHODSThe collected bacteria were treated by freeze-thaw and ultrasonic (method 1), ultrasonic (method 2), boiling (method 3), boiling and ultrasonic (method 4), respectively. The index such as state of bacteria broken, concentration of extracted protein and SDS-PAGE of protein were employed to evaluate the effects of above four methods.

RESULTSBeside the method 3, the other three methods could break the bacteria effectively, of which ultrasonic was the key factor. The pattern of SDS-PAGE which treated by method 1, method 2 and method 4 was almost same, but method 1 resulted in the best abundance. There was significantly difference among the four protein concentration extracted by four methods (P < 0.05). All methods exhibited good stability and reproducibility.

CONCLUSIONMethod of freeze-thaw and ultrasonic resulted in an efficient proteins extraction of Streptococcus mutans which demonstrated good stability and reproducibility and easy to handle.

OBJECTIVETo investigate the antibacterial activity of decoction of Radix glycyrrhizae against Streptococcus mutans (S. mutans) in vitro.

METHODSThe decoction of Radix glycyrrhizae was prepared by boiling particles of Radix glycyrrhizae, the diameter was 0.2-3.2 mm. In distilled water and filtered, the filtrate was collected for study. The minimal inhibitory concentration (MIC) and the minimal bactericidal concentration (MBC) of the decoction against S. mutans were detected using double dilution. The effect of decoction on growth and acidogenic profile of S. mutans were investigated by detecting the Abs of bacteria suspension and the pH value of medium at definite time intervals(0, 3, 7, 12, 23, 40 h) during cultured.

RESULTSThe MIC determined for decoction was 50 mg x mL(-1) and there was no bactericidal effect when concentration of decoction lower than 100 mg x mL(-1). The decoction inhibitted multiplication of bacteria significantly and the effects became stronger with concentration increasing. The decoction also inhibitted S. mutans producing acid and the effect became stronger with concentration increasing. The most efficient inhibition were observed when incubated 12 hours.

CONCLUSIONThe decoction of Radix glycyrrhizae can inhibite the growth and acid-production of S. mutans in vitro.
