Objective To systematically evaluate the effectiveness and safety of Elemene combined with radiotherapy for intervention in brain metastasis from pulmonary neoplasms. Methods Articles of clinical randomized controlled trials about Elemene combined with radiotherapy for intervention in brain metastasis from pulmonary neoplasms from the establishment of the databases to October of 2016 from CNKI, CBM, Chongqing Weipu, Wanfang database, Cochrane Library, PubMed and Embase were retrieved by computers. Bias risk assessment tools in Cochrane systematic evaluation handbook 5.1.0 was used to conduct quality evaluation for included articles. RevMan5.3 software was used to carry out Meta-analysis. Results Totally 12 articles and 839 patients were included. Results of Meta-analysis showed that Elemene combined with radiotherapy had more obvious curative effect on narrowing the neoplasm compared with pure radiotherapy [OR=2.73, 95%CI (1.97, 3.77), P<0.000 01], and improve patients' life quality at the same time [OR=3.85, 95%CI (2.23, 6.65), P<0.000 01], and relieve adverse reactions [OR=4.16, 95%CI (2.40, 7.22), P<0.000 01]. Conclusion Elemene combined with radiotherapy for intervention in brain metastasis from pulmonary neoplasms shows confirmed efficacy, and is relatively safe. But whether the program should be widely used in clinic, more large sample, multi-center, and high-quality clinical randomized controlled trials are still needed.

Objective To study the incidence and risk factors of post-operative pain after receive offpump coronary artery bypass grafting(OPCAB) and totally endoscopic coronary artery bypass graft on beating heart(BH-TECAB).Methods Totals of 80 patients received coronary artery bypass grafting were divided into two groups according to the different of operation procedure,BH-TECAB group(40 cases)and OPCAB group(40 cases).Basic situation,anesthesia conditions,surgical conditions,postoperative situation,and the incidence and degree of postoperative pain in two groups were collected.Results There was no significant difference between two groups in the basic situation.All patients had no postoperative complications and recovered smoothly.The incidence of 1-degree,2-degree and 3-degree postoperative pain in the BH-TECAB group [ 32.5％ ( 13/40),7.5％ (3/40) and 2.5％ ( 1/40 ) ] was significantly lower than that in the OPCAB group [45.0％ ( 18/40),15.0％ (6/40) and 10.0％ (4/40) ],the difference was significant (P ＜0.05).The time of breathing machine using,blood transfusion in 24 hours,the amount of flow in BH-TECAB group,respectively,was ( 14.35 ± 1.66 ) h,( 54.79 ± 15.69 ) ml,( 227.12 ± 120.38 ) ml,that significantly lower than that in OPCAB group which was ( 18.64 ± 1.57) h,( 120.75 ± 20.98 ) ml and ( 389.17 ± 138.66 ) ml,the difference was significant ( P ＜ 0.05 ).Conclusions The different of the operation procedure influences the incidence of postoperative pain of patients receive coronary artery bypass grafting.BH-TECAB has the features of mini-wound,less pain and fast healing.

Congenital coronary sinus anomalies are extremely rare, and they have received relatively little attention. This is probably due to the lack of both clinical symptoms and significant cardiac functional disturbance. We present two cases of a coronary sinus anomaly and briefly review the literature. Recognizing and being familiar with the variations of a congenital coronary sinus anomaly in congenital heart disease may avoid a misinterpretation of cardiac catheterization findings and the troublesome disruption of coronary sinus blood return during the surgical management of cardiac lesions.

Polyamidoamine-polyethylene glycol (PAMAM-PEG) copolymers were synthesized using IPDI as coupling reagent by two-step method. The copolymers were characterized by IR spectrum and 1H NMR spectrum, and the PEG conjugating ratios of the copolymers were calculated equal to 10% and 30% separately. MTT assay indicated that after PEGylation a lower cytotoxicity of the copolymers could be found, and with increasing PEG conjugating ratio the cytotoxicity decreased obviously. Agarose gel retardation assay demonstrated that PAMAM-PEG copolymers could be combined with DNA and PAMAM-PEG/DNA complexes were prepared by self-assembly. DLS measurement showed that when N/P > or = 50, the particle size of copolymer/ gene complexes was in a range of 150-200 nm, and the zeta potential was in a range of 10-25 mV. In vitro gene transfection illustrated that when N/P < or = 50, the gene transfection efficiency of PAMAM-PEG copolymers was a little less than that of PAMAM-G5, but the transfection efficiency can be raised by increasing N/P ratio or transfection time. Considering both cytotoxicity and transfection efficiency aspects PAMAM-PEG-13 was more effect than PAMAM-PEG-39 in PEGylation.

OBJECTIVETo investigate the expression characteristics of the gene of coiled-coil domain-containing protein 70 (Ccdc70) in the mouse testis and its potential role in spermatogenesis.

METHODSUsing expression profile microarray, we screened the mouse testis-specific gene Ccdc70, studied its expression characteristics in the mouse testis by RT-PCR, real-time PCR, Western blot and immunohistochemistry, followed by bioinformatic analysis of the Ccdc70 protein.

RESULTSThe Ccdc70 gene was expressed highly in the testis but lowly in the epididymis of the mice. The Ccdc70 protein was expressed mainly in the spermatocytes and round spermatids of the testis and in the epithelial cells of the epididymis. Bioinformatic analysis showed a structural domain in the Ccdc70 protein, which was highly conserved in mammalian evolution.

CONCLUSIONThe Ccdc70 gene is highly expressed in the mouse testis and mainly in the spermatocytes, round spermatids, and epididymal epithelial cells, which indicates that it is involved in the regulation of spermatogenesis and epididymal sperm maturation.

Purpose: Nowadays most children with congenital heart disease (CHD) are expected to survive to adulthood. The healthcare focus needs to pay close attention to the important developmental tasks during their growth process. The women with CHD face some challenges in their critically developmental stages during pregnancy, delivery, and even motherhood. The lived experience of being a mother needs to be further concerned. This study aimed to explore the lived experience of first-time mothers with CHD. Methods: Descriptive phenomenological design was adopted. Semi-structured interviews were conducted from April to August 2018 with 11 primiparous women with CHD, who were recruited from the pediatric and adult cardiology outpatient departments at a medical center and who had a child aged between 6 months and 3 years. Giorgi's phenomenological analysis method was employed. Results: Six main themes arose from the analysis: (1) recognizing pregnancy risks, (2) performing self-care for health, (3) building self-worth from my baby, (4) adapting to postpartum life and adjusting priorities, (5) enjoying being a first-time mother, and (6) the factors contributing to success in high-risk childbirth. Conclusions The experiences that occurred prior to and after labor that were identified in this study can assist women with CHD to more capably prepare for and understand the process of becoming a mother, including recognition of the importance of a prepregnancy evaluation. The findings of this study can help women with CHD to better understand the path to becoming a mother and prepare themselves for the challenges that lie ahead.

OBJECTIVETo evaluate the effect and safety of Pingchuan Yiqi Granule in treating bronchial asthma of qi-deficiency cold syndrome type (BS-QDC).

METHODSWith the randomized, positive agent parallel controlled design adopted, the 80 subjects enrolled were assigned in the ratio of 3:1 to two groups, the 60 patients in the trial group were treated with PYG and the 20 in the control group treated with Ruyi Dingchuan Pill (RDP), with the therapeutic course consisting of 7 days for both groups. The clinical effects, effects on TCM syndrome and the changes of lung function after treatment were observed.

RESULTSThe effect of the treatment on asthma in the trial group: clinically controlled rate was 6.67%, markedly effective rate 51.67%, improved rate 33.33% and ineffective rate 8.33%; and the corresponding rates in the control group were 5.00%, 50.00%, 30.00%, and 15.00% respectively. Comparison between the two groups showed insignificant difference (P>0.05). The effect on TCM syndrome in the treated group: clinically controlled rate was 11.67%, markedly effective rate 58.33%, effective rate 21.67% and ineffective rate 8.33%; and those in the control group were 10.00%, 50.00%, 30.00% and 10.00% respectively, also showing insignificant difference between the two groups (P>0.05). Lung function test showed that the change on forced expiratory volume in 1 second (FEV1) after treatment in the trial group was of statistical significance (P<0.05), but no significant difference was shown in the change of peak expiratory flow (PEF, P>0.05); while the changes in the control group were just the opposite, showing insignificance in FEV1 (P>0.05) but significance in PEF (P<0.05). Comparison of the therapeutic effect on lung function between the two groups showed no significant difference (P>0.05). No adverse reaction was found in either group in the course of treatment.

CONCLUSIONPYG used to treat BS-QDC is effective and safe, it's effect is similar to that of RDP.

Purpose: This study aimed to compare the ability of B-mode ultrasonography and magnetic resonance imaging (MRI) to predict the repairability of large-to-massive rotator cuff tears (RCTs). Methods: This cross-sectional study included participants with large-to-massive RCTs who underwent arthroscopic repair. B-mode ultrasonography and MRI were conducted prior to arthroscopic repair. B-mode ultrasonography was used to evaluate the echogenicity of the rotator cuff muscle using the Heckmatt scale. Intra-rater and inter-rater reliabilities were examined for two independent physicians. MRI was used to evaluate the degrees of tendon retraction, fatty infiltration of rotator cuff muscles, and muscle atrophy. Finally, two experienced orthopedic surgeons performed surgery and decided whether the torn stump could be completely repaired intraoperatively. Results: Fifty participants were included, and 32 complete repairs and 18 partial repairs were performed. B-mode ultrasonography showed good intra-rater reliability and inter-rater reliability for assessment of the muscle echogenicity of the supraspinatus and infraspinatus muscles. The correlation coefficients between B-mode ultrasound findings and MRI findings showed medium to large effect sizes (r=0.4-0.8). The Goutallier classification of the infraspinatus muscles was the MRI predictor with the best discriminative power for surgical reparability (area under the curve [AUC], 0.89; 95% confidence interval [CI], 0.81 to 0.98), while the Heckmatt scale for infraspinatus muscles was the most accurate ultrasound predictor (AUC, 0.85; 95% CI, 0.74 to 0.96). No significant differences in AUCs among the MRI and ultrasound predictors were found. Conclusion B-mode ultrasonography was a reliable examination tool and had a similar ability to predict surgical reparability to that of MRI among patients with large-to-massive RCTs.

BACKGROUNDDecreases in the bioavailability of rifampicin (RFP) can lead to the development of drug resistance and treatment failure. Therefore, we investigated the relative bioavailability of RFP from one four-drug fixed-dose combination (FDC; formulation A) and three two-drug FDCs (formulations B, C, and D) used in China, compared with RFP in free combinations of these drugs (reference), in healthy volunteers.

METHODSEighteen and twenty healthy Chinese male volunteers participated in two open-label, randomized two-period crossover (formulations A and C) or one three-period crossover (formulations B and D) study, respectively. The washout period between treatments was 7 days. Bioequivalence was assessed based on 90% confidence intervals, according to two one-sided t-tests. All analyses were done with DAS 3.1.5 (Mathematical Pharmacology Professional Committee of China, Shanghai, China).

RESULTSMean pharmacokinetic parameter values of RFP obtained for formulations A, B, C, and D products were 11.42 ± 3.41 μg/ml, 7.86 ± 5.78 μg/ml, 13.05 ± 6.80 μg/ml, and 16.18 ± 3.87 μg/ml, respectively, for peak plasma concentration (C max ), 91.43 ± 30.82 μg·h-1·ml-1 , 55.49 ± 37.58 μg·h-1·ml-1 , 96.50 ± 47.24 μg·h-1·ml-1 , 101.47 ± 33.07 μg·h-1·ml-1 , respectively, for area under the concentration-time curve (AUC 0-24 h ).

CONCLUSIONSAlthough the concentrations of RFP for formulations A, C, and D were within the reported acceptable therapeutic range, only formulation A was bioequivalent to the reference product. The three two-drug FDCs (formulations B, C and D) displayed inferior RFP bioavailability compared with the reference (Chinese Clinical Trials registration number: ChiCTR-TTRCC-12002451).

There are many different opinions on dose conversion of famous classical formulas from Treatise on Febrile Diseases or Synopsis of the Golden Chamber, which has become a difficult point in research and development of famous classical formulas. At present, the clinical application dose of Banxia Houpotang is similar to the viewpoint that 1 Liang is equivalent to 3 g, in order to provide scientific basis for this conversion method, this paper systematically evaluated the effectiveness of Banxia Houpotang in intervening globus hystericus. Randomized controlled trials (RCTs) of Banxia Houpotang in intervening globus hystericus from CNKI, VIP, Wanfang Data, China Biology Medicine (CBM), Web of Science and PubMed databases were collected online, the retrieval time was from inception to April 1, 2019. Two reviewers independently screened the literature, extracted the data and assessed the risk of bias of the included studies. Then, Meta analysis was performed by RevMan 5.3 software. A total of 17 RCTs involving 1 575 patients were included. The effective rate [relative risk (RR)=1.24, 95%confidence interval (CI) (1.18, 1.30), P<0.000 01] and the curative rate [RR=1.76, 95%CI (1.45, 2.15), P<0.000 01] of Banxia Houpotang in intervening globus hystericus were all better than the control group. Current evidence shows that Banxia Houpotang under the conversion of 3 g in 1 Liang has a significant effect on intervention of globus hystericus. Due to the limitations of quantity and quality of the included studies, the above conclusions need to be verified by more high-quality studies, but the author suggests that such dose conversion should be considered in the research and development of famous classical formulas.
