To systematically review the efficacy and safety of Tongmai Yangxin Pills in treatment for angina pectoris of coronary heart disease. CNKI, WanFang, VIP, SinoMed, PubMed, EMbase and the Cochrane Library databases were retrieved online to collect randomized controlled trials(RCTs) of Tongmai Yangxin Pills for angina pectoris of coronary heart disease since the establishment to November 2018. Two investigators screened out literatures independently, extracted data and assessed the risk of bias of included studies. The risk assessment of included references was made according to criteria recommended by Cochrane Handbook 5.3. Meta-analysis was then performed by RevMan 5.3 software. A total of 9 RCTs were included. The results of Meta-analysis showed that compared with the single application of chemotherapy, the combined administration with Tongmai Yangxin Pills and Western medicine could significantly improve the clinical efficacy of angina(RR=1.22, 95%CI[1.13, 1.31]), the improvement rate of electrocardiogram(RR=1.31, 95%CI[1.21, 1.42]), and the clinical efficacy of traditional Chinese medicine(TCM) syndrome(RR=1.17, 95%CI[1.02, 1.35]). Only one study reported adverse events, while 5 studies reported no adverse event. According to current evidences, in the treatment of angina pectoris of coronary heart disease, Tongmai Yangxin Pills has a better clinical efficacy in the treatment of angina pectoris of coronary heart disease in terms of the improvement rate of electrocardiogram and the clinical efficacy of TCM syndrome. Due to the limited quality and quantity of the included studies, more high-quality studies are required to verify the above conclusions.

Background: Right upper lobectomy (RUL) for lung cancer with different dissecting orders involves the most vari-able anatomical structures, but no studies have analyzed its effects on postoperative recovery. This study compared the conventional surgical approach, VAB (dissecting pulmonary vessels first, followed by the bronchus), and the alter-native surgical approach, aBVA (dissecting the posterior ascending arterial branch first, followed by the bronchus and vessels) on improving surgical feasibility and postoperative recovery for lung cancer patients. Methods: According to the surgical approach, consecutive lung cancer patients undergoing RUL were grouped into aBVA and VAB cohorts. Their clinical, pathologic, and perioperative characteristics were collected to compare periop-erative outcomes. Results: Three hundred one patients were selected (109 in the aBVA cohort and 192 in the VAB cohort). The mean operation time was shorter in the aBVA cohort than in the VAB cohort (164 vs. 221 min, P < 0.001), and less blood loss occurred in the aBVA cohort (92 vs. 141 mL, P < 0.001). The rate of conversion to thoracotomy was lower in the aBVA cohort than in the VAB cohort (0% vs. 11.5%, P < 0.001). The mean duration of postoperative chest drainage was shorter in the aBVA cohort than in the VAB cohort (3.6 vs. 4.5 days, P = 0.001). The rates of postoperative complica-tions were comparable (P = 0.629). The median overall survival was not arrived in both cohorts (P > 0.05). The median disease-free survival was comparable for all patients in the two cohorts (not arrived vs. 41.97 months) and for patients with disease recurrences (13.25 vs. 9.44 months) (both P > 0.05). The recurrence models in two cohorts were also comparable for patients with local recurrences (6.4% vs. 7.8%), distant metastases (10.1% vs. 8.3%), and both (1.8% vs. 1.6%) (all P > 0.05). Conclusions: Dissecting the right upper bronchus before turning over the lobe repeatedly and dissecting veins via the aBVA approach during RUL would promote surgical feasibility and achieve comparable postoperative recovery for lung cancer patients.

The study was aimed to observe mir-210 expression in liver tissue of acute cold stress rat and predict the function of mir-210 in cold stress. Thirty SPF Wistar male rats which were 12-week-old and weighed (340 ± 20) g were used. The rats were pre-fed in normal room temperature for one week, and then were randomly divided into acute cold stress group at (4 ± 0.1) °C and normal control group at (24 ± 0.1) °C. After the rats were treated with cold stress for 12 h, the liver tissue was extracted and the gene expression of mir-210 was assayed using qRT-PCR. The results demonstrated that the gene expression of mir-210 was significantly enhanced in acute cold stress group compared with that in normal control group (n = 3, P < 0.01). The bioinformatics analysis showed that mir-210 has over hundreds of target genes and four kinds of target genes such as E2F3, RAD52, ISCU and Ephrin-A3 are more relative with liver cold stress. ISCU regulates the cell respiratory metabolism and Ephrin-A3 is related with cell proliferation and apoptosis. On the other hand, up-regulated mir-210 affects the DNA repairing mechanism which usually leads to genetic instabilities. Our results suggest that cold stress-induced up-regulation of mir-210 in liver harmfully influences cell growth, energy metabolism and hereditary.

UNLABELLEDObjective: To compare the clinical influence of intramedullary versus extramedullary alignment guides on total knee arthroplasty (TKA) in terms of alignment of the lower limbs,intraoperative tourniquet time,and postoperative complications.

METHODSWe retrospectively analyzed the clinical data of 105 patients(210 knees)undergoing bilateral TKA from February 2012 to November 2013. All patients were divided to two groups:40 [age:(66.65 ± 9.57)years] were implanted using intramedullary guides on the tibia and 65 [age:(65.29±9.27)years] were implanted using extramedullary guides on the tibia. Alignment of lower limb,tibial component angle in the sagittal plane,tourniquet time,and postoperative complications were compared.

RESULTSThe gender ratio,age,height,weight,body mass index,and preoperative alignment of lower limbs were not significantly different between these two groups (all P>0.05). The average coronal alignment of lower extremity was (179.69 ± 2.91)° in the intramedullary guides group and (178.26 ± 3.38)° in the extramedullary guides group (P=0.002). The alignment of lower limbs on neutral and valgus position were found in 68 cases(85.00%)in the intramedullary group and in 94 cases (72.31%) in extramedullary group (P=0.033) ;the tourniquet time was (79.46 ± 12.06) min in the intramedullary group and (84.68 ± 8.02) min in the extramedullary group (P=0.001); the postoperative complication rate was 6.25% in intramedullary group and 3.07% in extramedullary group (P=0.279).

CONCLUSIONAlignment and tourniquet time can be significantly improved by the intramedullary instrumentation,while the incidence of complications associated with intramedullary instrumentation is higher than extramedullary instrumentation.

Objective To evaluate the transfusion rates and identify perioperative factors associated with allogeneic blood transfusion ( AllTx) after primary total knee arthroplasty ( TKA) with routine use of low-molecu-lar-weight heparins .Methods We retrospectively studied the transfusion rate of 1165 consecutive patients who underwent primary TKA between January 2005 and December 2011 .Totally 34 independent variables were ana-lyzed in 617 primary unilateral TKAs without autologous blood predonation for requirement of AllTx .Multiple re-gression analysis model was used to identify risk factors associated with perioperative blood transfusion .Results Overall, 58.2% (678/1165 ) of patients required AllTx .The median number of units transfused was 2.7 U ( range:1 to 13 U).The AllTx rate was 40.0%(278/695) in unilateral TKA procedures and 85.1%(400/470) in one-stage bilateral TKA procedures .Univariate analysis demonstrated the risk of transfusion was independently predicted by the patients'age at surgery ( P<0.0001 ) , preoperative hematocrit ( P<0.0001 ) , preoperative he-moglobin concentration (P<0.0001), American Society of Anesthesiologists (ASA) score ≥3 (P=0.004), surgical time ( P=0.004 ) , and tourniquet time ( P=0.050 ) .Multivariate Logistic regression analysis confirmed significant relationship between allogeneic blood transfusion and age ( P <0.0001 ) , preoperative hemoglobin ( P<0.0001 ) , and surgical time ( P<0.0001 ) .Conclusions AllTx rate is high in TKA procedures , especial-ly in one-stage bilateral TKA procedures .Patient's age, preoperative hemoglobin level , and surgical time are helpful in identifying high-risk patients who require postoperative blood transfusion .
