Objective To explore the curative effect of the single pore video-assisted thoracoscopic surgery and thoracic closed drainage for patients with acute pyothorax by comparing the advantage and disadvantage of two methods.Methods The clinical data of 65 patients with acute pyothorax in our hospital from January 2012 to June 2015 were retrospectively analyzed.Of which 30 patients underwent single pore video-assisted thoracoscopic surgery were as observation group,35 cases received thoracic closed drainage were as the control group.The cura-tive effect of two methods for acute pyothorax was compared by analyzing the result data of two groups.Results The postoperative chest tube indwelling time,length of hospital stay,postoperative antibiotics of observation group were significantly less than those of the control group,the difference was statistically significant(P<0.05).And the incidence of postoperative complications,the proportion of the chronic pyothorax and secondary tube rate of observation group were lower than those of the control group,the difference was statistically significant(P<0.05). Conclusion The single pore video-assisted thoracoscopic surgery is safe and effective for treatment of acute pyothorax, which is worth promoting.

American doctor Koretz and his colleagues have collected the documents on randomized control test(RCT) of total parenteral nutrition(TPN) during past 30 years since 1974.With stringent standard,Dr.Koretz et al performed the Meta-analysis to evaluate the efficacy of TPN.This article summarized the result of Koretz's Meta-analysis and also reviewed the efficacy of TPN on some special clinical conditions such as acute pancreatitis,HIV infection,respiratory disease,burns,home TPN et al.The result couldn't determine the curative effect of TPN.TPN is usually not recommended to be routinely applied on hospital patients,but applicable to selective patients.

Objective:To develop a simple and efficient method for constructing a middle fragment-deleted mutant of MHC class Ⅱ molecule transactivator(CⅡTA)mutant with the 109~(th)to 226~(th) amino acid codons deleted.Methods: Two gene fragments at each end of the deleted CⅡTA gene were obtained by OE-PCR method and were mixed together for 8 PCR cycles without primers to achieve effective overlapping,then 2 primers was added for amplification of the desired fragments.The amplification products were subsequently cloned into eukaryotic vector pIRES for identification.Results: A mutant of CⅡTA with the 109~(th)to 226~(th) amino acids deleted was successfully constructed.Conclusion: This modified OE-PCR technique overcomes some shortcomings of traditional method and is very suitable for constructing mutants with middle fragment deletion,making it worth to be popularized.

Objective To identify the expression of long non-coding RNAs(lncRNAs) and their putatively modulated cytokines in human immunodeficiency virus(HIV)-1 infected monocytes and to explore the role of lncRNAs in immunomodulation of HIV-affected host cells.Methods RNAs arrays were used to screen the lncRNAs differentially expressed in HIV-infected monocytes and subsequently confirmed by quantitative real time PCR (qRT-PCR).A siRNA was designed and transfected to the human monocytes, followed by interleukin(IL)-1β, IL-10 and tumor necrosis factor(TNF)-α detection with ELISA.Results The results of the screening assays and qRT-PCR showed that the expression of lncRNA-n266623 was up-regulated in monocytes after HIV-1 infection;the secretions of IL-1β,IL-10 and TNF-α in human monocytes were significantly enhanced following transfection of siRNA targeting lncRNA-n266623 in the monocytes.Conclusion The HIV-1 infection can promote the expression of lncRNA-n266623 which may inhibit the expressions of IL-1β, IL-10 and TNF-α in monocytes and negatively regulate the immune response to HIV-1 infection.

Objective To study the risk values of glycosylated hemoglobin ( HbA1c) screening patients with diabetes mellitus(DM) and pre-diabetes(PreD) in different age and sex.Methods HbA1c results from10 840 in Taizhou Hospital in 2012 were retrospectively collected , and CHAID analysis of decision tree was used in preliminary hierarchy .Age was further divided into five groups according to the preliminary results , then one-way ANOVA and linear regression were utilized to determine the differences between age groups and the prediction intervals (PI) of HbA1c,respectively.The upper limit value of 95%PI of HbA1c was set as diabetes risk values ( DRVs).By comparison of the sensitivity of DM patients screening by DRVs in 1 889 cases whose HbA1c were between 6.0%to 6.5%and the upper limit value of traditional HbA1c reference intervals to verify the screening value ofDRVs .Then the DRVs of HbA1c were utilized to screen DM in the population whose HbA 1c is were 6.0%-6.5% in 2008,and followed their re-examination records toverify the screening value of the DRVs toin PreD patients. Results (1) On the basis of the initially root of decisiontree by age , the populationwas divided into 9 groups ( P =0.000, F =231.462).By calculatingthe 95% confidence interval(CI) of each group and merging reasonably,it was finally divided into 5 groups:20-30years,31-40years,41-50years,51-60years and >60years (F=434.342, P=0.000).(2)Using the method of linear regression , the 95% PI of HbA1c of the 5 groups showed as following:20-30 years, males 4.6%-5.9%, females 4.6%-5.9%.31-40 years, males 4.8%-6.0%, females 4.7%-6.0%.41-50 years, males 4.9%-6.2%, females 4.8%-6.1%.51-60 years, males 5.0%-6.3%, females 4.9%-6.2%.>60 years, males 5.1%-6.4%, females 5.0%-6.3%.The traditional HbA1c reference interval was4.8%-6.3%.(3) The screening sensitivity of DM by the upper limit value of traditional HbA1c reference interval and DRVs in group which HbA1c was between 6.0%-6.5% were 34.5%and 48.1%,respectively.(4) Reviewing of the group with HbA1c between 6.0%-6.5% and not diagnosed as DM in 2008, 49 hadnegative DM screening results by using the upper limit value of traditional HbA1c reference interval but were positive in our setting DRVs , and 13 have developed to DM now , which accounted for 26.5%.Conclusion HbA1c DRVs need to be set hierarchically between different age and sex groups as a supplement to the traditional reference interval , which has a great significance for the diagnosis and treatment of DM and also forthe screening and intervention of PreD patients.

Objective To study the characteristic and influential factor of the hidden blood loss after total knee arthroplasty (TKA) so as to provide a reference frame for clinical work. Methods There were 75 patients with osteoarthritis of the knee who were operated with unilateral primary TKA. The patients including 21 males and 54 females at a mean age of 68.7 years were retrospectively analyzed.The perioperative blood loss and the hidden blood loss following TKA were calculated by Gross formula. It was analyzed that if the perioperative blood loss and the hidden blood loss following TKA were affected by gender, haemostasis during operation with deflating tourniquet and reinfusion of the drained blood. Results The preoperative blood loss was (1551.3 ± 369.6) ml and the hidden blood loss was (792.3 ±228.6) ml. The hidden blood loss of male was significantly higher than that of female (P ＜ 0.05). The hidden blood loss was reduced by haemostasis during operation with deflating tourniquet (P ＜ 0.05) but was not affected by postoperative shed blood reinfusion. Conclusions The lowest value of Hct is a representative parameter for calculation of the hidden blood loss. There is no significant difference between male and female about the relative hidden blood loss. Haemostasis during operation with deflating tourniquet can reduce teh hidden blood loss but not affect the total perioperative blood loss. Reinfusion of the drained blood can reduce the transfusion rate but does not affect the total preoperative blood loss and the hidden blood loss.

Objective To investigate the efficiency of interventional treatment and intramuscular injection of methotrexate for the treatment uterine scar pregnancy.Methods 22 patients with uterine scar pregnancy were divided into two groups,group A (n =12),transvaginal color Doppler ultrasound to guide percutaneous interventional treatment;group B( n =10) intramuscular injection of methotrexate treatment.Mass size and β-HCG preoperation and 4 days,7 days,1 month postoperation were evalutaed respectively.Results The cure rate of interventional treatment and intramuscular injection of methotrexate for the treatment uterine scar pregnancy were 83.3％ and 40.0％ respectively.And the difference was statistically significant ( P ＜ 0.05 ).Conclusion Compared with intramuscular methotrexate treatment of uterine scar pregnancy,guided by vaginal ultrasonography involved the injection of methotrexate is more effective and have important clinical significance.
