Objective To evaluate the effectiveness and safety of tanreqing injection to children bronchial pneumonia.Methods PubMed,Ovid,CNKI,and data retrieval system of all places were searched to identify relevant studies from 2003 to November of 2014.The final documents were examined with inclusive and exclusive criteria.Results were pooled with meta-analysis on RevMan software to assess the efficacy of tanreqing injection to children bronchial pneumonia.Results The database was derived from 13 qualified studies that included a total of 1479 patients.Meta analysis showed that,compared to the control group,tanreqing injection treatment group resulted in higher effective rate [OR =2.96,95％ CI (2.22,3.96),P ＜0.01],shorter time of recovering the normal temperature [MD----0.53,95％ CI (-0.77,-0.29),P ＜ 0.01],shorter time of disappearance of cough [MD =-1.25,95％ CI (-2.14,-0.37),P ＜0.01],shorter time of lungrale [MD=-1.00,95％ CI(-1.4,-0.6),P ＜0.01],and shorter time of hospitalization time [MD =-1.35,95％ CI (-1.83,-0.86),P ＜ 0.01].Significant difference was observed between control and treatment groups.Conclusions This study showed that tanreqing injection appeared to be more effective for children bronchial pneumonia.However,methodology showed low quality.The efficacy needs high-quality clinical trials to verify.

Objective:To evaluate the effectiveness and safety of anticoagulant therapy with rivaroxaban in atrial fibrillation( AF) pa-tients after radiofrequency catheter ablation( RFCA) . Methods:A retrospective analysis was performed in the study. Totally 141 AF pa-tients with RFCA in our hospital were enrolled from January 2014 to October 2015. The patients were divided into rivaroxaban group(70 patients)and warfarin group (71 patients). In rivaroxaban group,rivaroxaban(10 mg, po,qd)was given for at least 3 months after RFCA. In warfarin group,low molecular heparin (100 IU·kg-1,ih) was given before RFCA, and standard dose of warfarin (3-5 mg,po,qd) was given for at least 3 months by adjusting the INR within the range of 2. 0-3. 0 after RFCA as bridging therapy. The death rate, throm-boem bolism events and bleeding events between the groups were evaluated and companed groups. Results: There were no significant differences in baseline characteristics between the groups except the diastolic pressure. There were no significant differences in the death and thromboembolism events(transient cerebral ischemia , ischemic encephalopathy, 2/70 vs 4/71,P>0. 05)between the groups. There were no TIMI major bleeding events in both groups. There were no significant differences in minor bleeding events between the groups (3/70 vs 4/71,P>0. 05). Conclusion: Compared with those of warfarin,the effectiveness and safety of rivaroxaban show the similar effect in AF patients after RFCA. Rivaroxaban can be safely and effectively used in AF patients with low or middle risk of thromboembo-lism after RFCA.

OBJECTIVE:To compare the efficacy and safety of dabigatran and warfarin respectively used in atrial fibrillation patients after radiofrequency ablation(RFCA). METHODS:Data of 141 nonvalvular atrial fibrillation patients,who scheduled for RFCA,were retrospectively analyzed and divided into warfarin group(71 cases)and dabigatran group(70 cases)by different med-ication. Patients in warfarin group should stop warfarin if they took before,then changed to Low molecular weight heparin calcium injection 100 U/kg,subcutaneous injection,taking RFCA when INR was lower than 1.5,stopping low molecular weight heparin 12 h before surgery;Low molecular weight heparin calcium injection 100 U/kg was intravenously injected when surgery;orally tak-ing Warfarin sodium tablet 4.5 mg after 4-6 h,once a day,meanwhile bridged overlapping treated at least 3-5 d with low molecu-lar weight heparin;monitoring once INR every 3 d after surgery,maintaining INR 2.0-3.0,taking warfalin at least 3 months. Pa-tients in dabigatran group stopped taking the anticoagulant drugs when admission,then changed to Dabigatran etexilate capsule 110 mg(age≥70 years old or body mass<60 kg)or 150 mg(age<70 years old or body mass≥60 mg),twice a day;stopping dabig-atran 24 h before surgery,the same medication as warfalin group when surgery;orally taking dabigatran after 6 h,taking at least 3 months. The total mortality rate,incidence of stroke(transient cerebral ischemia,ischemic encephalopathy),peripheral thrombosis rate and incidence of bleeding after 1 and 3 month(s)in 2 groups were observed. RESULTS:There were no significant differences in the total mortality rate,incidence of stroke,peripheral thrombosis rate and incidence of bleeding after 1 and 3 month(s) in 2 groups(P>0.05). CONCLUSIONS:Dabigatran has similar anticoagulant efficacy and safety with warfarin in atrial fibrillation pa-tients after RFCA.

Objective To construct reference standards for detection and quantification of Klebsiella pneumoniae (K.pneumoniae) with SYBR Green I-based real-time PCR assay. Methods Primers were designed based on the published sequence of the phoE gene of K.pneumoniae. The standard was prepared by cell culture, PCR and T-A clone methods, and was identified by colony PCR and DNA sequencing. Results The standard curve showed a very good linear negative regression between threshold cycle (Ct) and Log starting quantity of copy number. The detection range was from 5.2 to 5.2×106 copies per reaction, and the detection limit was 6 copies per reaction. The coefficients of variance (CVs) of three parallel experiments were in the range of 0.05%-0.91%. Conclusion The reference standards have high stability and reproducibility. They can be used in the quantitative detection of K.pneumoniae.

Objective To explore the expression of PIWIL1 protein and DICER enzyme in hepa tocellular carcinoma (HCC) and their significance.Methods Immunohistochemical method was used to detect the expression of PIWIL1 and DICER in 47 cases of HCC and the adjacent HCC tissues.Western blot method was used to detect the expression of PIWIL1 and DICER in 31 cases of fresh HCC tissues and their adjacent HCC tissues.The relationship between PIWIL1 and DICER and their relationships were analysed with clinical features.12 cases of normal liver tissues were used as control group.Results The expression of PIWIL1 was high in HCC but low in normal liver tissues (P＜ 0.05).The expression of DICER was high in normal liver tissues but low in HCC (P＜0.05).The expression of PIWIL1 was positively correlated with invasion to adjacent tissues and histological differentiation (P＜0.05).The expression of DICER was negatively correlated with invasion to the adjacent tissues and histological differentiation (P＜0.05).There was a negative correlation between PIWIL1 and DICER (P＜ 0.05).Conclusions High expression of PIWIL1 and low/missing expression of DICER was related to pathological differentiation and invasion of adjacent tissues.

The therapeutic effects and adverse reactions were observed as well. Results: Safte and high-quality individualized pharmaceutical service was provided to the patient by the pharmaceutical care of the clinical pharmacist in anti-infection treatment. Conclusion:Through the above practice, clinical pharmacists have played a positive role in reasonable using of anti-infective drugs in patients with cardiac surgery.

Objective Extracorporeal membrane oxygenation is a cardiopulmonary supportive therapy. Since 2004, our institution has adopted venoarterial ECMO for adult patients who otherwise could not be weaned from cardiopulmonary bypass and patients experiencing postcardiotomy cardiogenic shock and/or pulmonary dysfunction unresponsive to conventional treatment algorithms. In this study, we reviewed our experience with ECMO support and tried to identify measurable values which might predict in-hospital mortality. Methods From January 2004 through December 2008, 50 of 21,298 adult patients received VA ECMO. We retrospectively analyzed clinical records of these 50 consecutive patients. Demographics, preoperative measurements, clinical characteristics at the time of ECMO implantation, ECMO related complications and in-hospital mortality were collected. Logistic regression analyses were performed to investigate predictors of mortality. A p value ≤0. 05 was accepted as significant. Results Mean ECMO duration was ( 110 ± 17 ) hours. 38 patients were weaned from ECMO and 33 patients survived upon discharge. The overall survival was 66%. In univariate analyses, duration of ECMO support, receiving cardiopulmonary resuscitation prior to ECMO setup, ECMO setup in ICU, pre-ECMO plasma lactate level, infection, lower limbs ischemia, renal failure, experiencing at least one ECMO related complications were all associated with in-hospital death. In a multiple logistic regression adjusted for other factors mentioned above, blood lactate level before initiation of ECMO was a risk factor associated with in-hospital mortality (OR 1. 27 95% CI 1. 042-1. 542 ). To evaluate the utility of pre-ECMO lactate in predicting mortality, a conventional receiver operating characteristic curve was produced. Sensitivity and specificity were optimal at a cut-off point of 12.6 mmol/L, with an AUC of 0. 752. The positive and negative predictive values were 73.3% and 83.9% respectively. Conclusion ECMO is a justifiable alternative treatment for postoperative refractory cardiac and pulmonary dysfunction which could rescue more than 60 percent of otherwise fatal patients. Patients with pre-ECMO lactate above 12.6mmol/L are at higher risks for in-hospital death. Evidence based therapy for this group of high risk patients is needed.

PURPOSE: A large number of studies have suggested the practicability and predictability of immediate implant function, but few studies have reported marginal bone level changes during sequential loading periods. The purpose of this study was to evaluate the marginal bone remodeling of immediately loaded self-tapping implants both at each time point and during each loading period between two time points. MATERIALS AND METHODS: The patients included in this retrospective study were treated with immediately loaded NobelSpeedy Replace implants between August 2008 and July 2009. Differences in the marginal bone level (MBL) at each time point and the marginal bone level change (ΔMBL) between two time points were analyzed with Bonferroni correction (P < .05). RESULTS: Overall, 24 patients (mean age, 47.3 ± 12.8 years) with 42 immediately loaded implants and a median follow-up of 6.5 years (IQR, 67.8 months) were included. The cumulative survival rate after 10 - 12 years was 95.2%. Continuous but slow marginal bone loss was observed during long-term follow-up. MBL at both 7.5 years and 11 years was significantly lower than that at loading, 6 months, 2 years and 4 years (P < .05). No bone loss difference was found in any period before 4 years of follow up (P > .05). The loading period of 4 years to 7.5 years showed the largest ΔMBL compared to those of other time periods (P < .05). CONCLUSION Slight bone loss occurred continuously, and more radical changes of marginal bone can be observed during the period of 4-7.5 years. Thus, long-term effective follow-up of immediately loaded implants is needed.

To seek convenient and effective method for reconstruction of edentulous jaw, Maló and his colleagues developed All-on-Four implant immediate-function concept. The principle of All-on-Four is to support the full-arch prosthesis by 4 implants and to achieve immediate loading after surgery. Its advantages include avoiding additional bone grafting, evading critical anatomical structures and immediate prosthesis. In recent years, All-on-Four technique has been widely utilized in clinical practice as a viable approach for edentulous patients. With the auxiliary of guided surgery and biomechanical researches, All-on-Four has achieved predictable clinical results. In this paper, the development, investigation of biomechanics and main points of surgery and prosthesis of All-on-Four were briefly reviewed.
