ABSTRACT
Objective: To study the non/hypo-response to hepatitis B vaccination in HIV-infected patients, identify the influencing factors and provide evidence for the development of hepatitis B prevention and control strategies and measures for special population. Methods: On the basis of the randomized controlled trial of 20 µg hepatitis B vaccine immunization at 0-1-6 month, 0-1-2-6 month and 60 µg hepatitis B vaccine immunization at 0-1-2-6 month, the HIV-infected patients who completed one-month follow-up after the full course vaccination were selected as study subjects. Quantification of antibody to hepatitis B surface antigen (anti-HBs) in serum samples was performed by using chemiluminescent microparticle immunoassay (CMIA) and demographic characteristics, disease history, HIV infection and treatment status of the study subjects were collected. Statistical analysis was conducted by χ2 test, t test, unconditional logistic regression and interaction analyses. Results: The non/hypo-response rates to hepatitis B vaccination were 34.65% (35/101), 24.49% (24/98) and 10.99% (10/91) in 20 µg group at 0-1-6 month or 0-1-2-6 month and 60 µg group at 0-1-2-6 month (P<0.001), respectively. Logistic regression analysis showed that after controlling for confounding factors, the risk for non/hypo-response was 0.22 times higher in HIV-infected patients receiving 60 µg hepatitis B vaccine at 0-1-2-6 month than in patients receiving 20 µg hepatitis B vaccine at 0-1-6 month (95%CI: 0.10-0.50), the risk for non/hypo-response was higher in men than in women (OR=3.65, 95%CI: 1.88-7.07), and the risk for non/hypo-response was 2.64 times higher in those without hepatitis B vaccination history than in those with hepatitis B vaccination history (95%CI: 1.10-6.32). Moreover, there were multiplicative interactions between immunization schedule and gender (OR=2.49, 95%CI: 1.24-5.00). Conclusion: The non/hypo-response rate to hepatitis B vaccination was significantly lower in HIV-infected patients receiving 60 µg hepatitis B vaccine at 0-1-2-6 month than in those receiving 20 µg hepatitis B vaccine at 0-1-6 month and 0-1-2-6 month. Gender, vaccination schedule and history of hepatitis B vaccination were the influencing factors of the non/hypo-response to hepatitis B vaccination. There was a multiplicative interaction between vaccination schedule and gender, and men receiving 20 µg hepatitis B vaccines had a higher risk for non/hypo-response to hepatitis B vaccination.

ABSTRACT
Objective:Based on the high-throughput detection technique of multiplex PCR combined with matrix-assisted laser desorption/ionization time-of-flight mass spectrometry, constructing the characteristic SNP profiles of different strains, and establishing a rapid, accurate and highly sensitive method for the diagnosis of bloodstream infection pathogens.Methods:Seven kinds of pathogens such as common Escherichia coli were selected as target. The multiple PCR reaction conditions was optimized, and the characteristic peaks of each target bacteria were detected by MALDI-TOF MS to establish the joint detect system. Common primer pairs and central homo-sequence primer pairs were designed to analyse the formation of primer dimer. Using simulated bacterial infection blood samples with detection system to determine specificity and sensitivity. One hundred and fifty blood samples from suspected bacteremia patients were collected from June to September 2020 in a hospital in Beijing, and the identification results were compared to traditional identification method of clinical application that are using χ 2 test. Results:The cycle threshold (Ct) value of the central homo-sequence primers that were designed were more than 38, with a delay of 6-10 cycles. The joint mass spectrometry detection system could detect seven kinds of bacteria divided into two groups at the same time. The target bacteria can be detected specific product of the peak, and the clinical strains other than the target strains only had primer peaks. All maps had non-specific miscellaneous peaks. The sensitivity of Escherichia coli could reach 50 CFU/ml, and the detection limit of other bacteria was 100 CFU/ml. The detection results of 150 patients showed that 46 cases were positive by traditional method. The positive rate was 30.67% (46/150), including two cases of mixed infection. Forty-eight cases were positive by mass spectrometry, and the positive rate was 32.0% (48/150), including three cases of mixed infections. The negative coincidence rate was 100% (101/101). The comparison of the two methods showed that the P=0.625>0.01, the Kappa=0.938, the sensitivity and specificity was 97.82%(45/46) and 97.11%(101/104), respectively. There was no significant difference between the two methods, and the results of nucleic acid mass spectrometry could also be used in clinic. Conclusions:The established detection system can not only quickly and accurately detect seven common pathogens causing bloodstream infection, and effectively shorten the time needed for traditional culture and identification, but also can detect multiple bacterial mixed infections at the same time to make up for the possibility of missed detection. Besides, the method can also be used to identify other bacteria.

ABSTRACT
BACKGROUND@#The mechanism and characteristics of early and late drug-eluting stent in-stent restenosis (DES-ISR) have not been fully clarified. Whether there are different outcomes among those patients being irrespective of their repeated treatments remain a knowledge gap.@*METHODS@#A total of 250 patients who underwent initial stent implantation in our hospital, and then were readmitted to receive treatment for the reason of recurrent significant DES-ISR in 2016 were involved. The patients were categorized as early ISR (<12 months; E-ISR; n = 32) and late ISR (≥12 months; L-ISR; n = 218). Associations between patient characteristics and clinical performance, as well as clinical outcomes after a repeated percutaneous coronary intervention (PCI) were evaluated. Primary composite endpoint of major adverse cardiac events (MACEs) included cardiac death, non-fatal myocardial infarction (MI), or target lesion revascularization (TLR).@*RESULTS@#Most baseline characteristics are similar in both groups, except for the period of ISR, initial pre-procedure thrombolysis in myocardial infarction, and some serum biochemical indicators. The incidence of MACE (37.5% vs. 5.5%; P < 0.001) and TLR (37.5% vs. 5.0%; P < 0.001) is higher in the E-ISR group. After multivariate analysis, E-ISR (odds ratio [OR], 13.267; [95% CI 4.984-35.311]; P < 0.001) and left ventricular systolic dysfunction (odds ratio [OR], 6.317; [95% CI 1.145-34.843]; P = 0.034) are the independent predictors for MACE among DES-ISR patients in the mid-term follow-up of 12 months.@*CONCLUSIONS@#Early ISR and left ventricular systolic dysfunction are associated with MACE during the mid-term follow-up period for DES-ISR patients. The results may benefit the risk stratification and secondary prevention for DES-ISR patients in clinical practice.

ABSTRACT
Objective To investigate the effect of pre-implanted anti-adhesion patch under laparoscopic approach in a Miles' operation on the incidence of parastomal hernia in elderly patients.Methods A total of 68 patients with low rectal cancer admitted into our general surgery department were enrolled in the study from January 2012 to January 2015.All patients received laparoscopic assisted Miles operation.According to whether or not the pre-implanted anti adhesion patch was used during the operation,the 68 cases were divided into pre-implanted patch group(n=38)and the non-implanted patch group(n=30).The operation states,postoperative complications,complications during follow-up and 3-year survival rate were compared between the two groups.Results The operation duration was longer in the pre-implanted patch group than in the non-implanted patch group[(235.7± 33.6)min vs.(94.3±28.9)min,t =5.36,P=0.000].The incidence of complications was lower in the pre implanted patch group than in the non-implanted patch group at 3 years after operation[10.5％ (4/38)vs.90.0％(27/30),x2 =42.69,P =0.000].The local recurrence rate,distant metastasis rate and 3-year overall survival rate had no significant difference between the two groups[23.7 ％ (9/38)vs.23.3％ (7/30),31.6％ (12/38) vs.33.3％ (10/30) and 71.1％ (27/38) vs.70.0％ (21/30)respectively,x2=0.06,0.02 and 0.01,P=0.800,0.878 and 0.925].Conclusions Pre-implanted anti-adhesion patch under laparoscopic approach can significantly reduce the incidence of parastomal hernia in elderly patients after a Miles' operation,which is worthy of promotion.
ABSTRACT
Currently, the pathogenesis of nonalcoholic steatohepatitis (NASH) remains unclear, while the theory of "two hits"is insufficient to explain the pathogenesis of NASH in all cases.More and more attention has been paid to the relationship between the change in gut microbio - ta and the development and progression of NASH in recent years .The energy metabolism disorder, lipopolysaccharide endotoxemia, increased endogenous ethanol production, bile acid metabolism disorder, altered choline metabolism, and immune dysfunction caused by gut microbiota are related to NASH.This article reviews the role of gut microbiota in the development and progression of nonalcoholic steatohepatitis .
ABSTRACT
Objective To investigate the functional recovery and the effect of CNTF antibody block to the bone marrow mesenchymal stem cells (BMSCs) transplantated by Abdominal aortic on the downstream signaling pathways STAT3/Caspase-9 in spinal cord ischemic reperfusion injury in rats.Methods Adult female SD ratswere assigned randomly to 4 groups. The neurological functional status of the animals was assessed with BBB scores, the Motor evoked potentials (MEP) and Cortical somatosensory evoked potentials (CSEP).The IHC were used to detect the the expressional changes of CNTF, then Western blot and RT-PCR were used to detect the expressional changes of STAT3、p-STAT3、CNTF and Caspase-9 in the ischemic segments of spinal cord.Results Compared with the sham group, in the SCIRI rats, the BBB scores were markedly decreased at all time points (P＜0.01), the latency and the amplitude of MEP and CSEP was longer and lower at 14 d post operation (P＜0.01), and this change was the most significant in the control group the second in the CNTF block group, and the last in the transplantation group, Resutts between each two groups were statistically significant (P＜0.05). At 7 d post operation, compared with the sham group, the immunoreactive products of CNTF were decreased in the CNTF block group (P＜0.05), but were increased (P＜0.05) in the control group and the transplantation group (P＜0.05), and results in the transplantation group were higher than in the control group (P＜0.05). At 7 d post operation, compared with the sham group, the m RNA and protein level of CNTF、STAT3、 p-STAT3 were decreased obviously in CNTF block group (P＜0.05), the levels were increased in the control group and the transplantation group (P＜0.05), and the levels in the transplantation group were higher than that in the control group (P＜0.05); but the m RNA and protein level of Caspase-9 were only decreased in the transplantation group (P＜0.05), the level was increased in the CNTF block group and the control groups (P＜0.05), and the level in the CNTF block group was more significantly increased than that in the control group (P＜0.05). At 14 d post operation, in CNTF block group, the m RNA and protein level of CNTF、STAT3、p-STAT3 were significantly higher than that in the sham group and the control group (P＜0.05), and the m RNA and protein level of caspase-9 was higher than that in the sham group (P＜0.05), but lower than that in the control group (P＜0.05), there were not statistically different in the level of each factor compared with transplantation group (P＞0.05). Conclusions BMSCs, transplanted by the abdominal aorta, can promote the expression of CNTF in the injuried spinal cord and significantly improve the hind limb function recovery by CNTF-mediated signaling pathway downstream of STAT3/Caspase-9 SCIRI in rats, but the role of BMSCs can be weakening by CNTF block that inhibited STAT3/Caspase-9 signaling pathway.
ABSTRACT
Background@#Fibroblasts were the main seed cells in the studies of tissue engineering of the pelvic floor ligament. Basic fibroblast growth factor (bFGF) and epidermal growth factor (EGF) were widely studied but at various concentrations. This study aimed to optimize the concentrations of combined bFGF and EGF by evaluating their effects on proliferation and collagen secretion of fibroblasts.@*Methods@#Fibroblasts were differentiated from rat adipose mesenchymal stem cells (ADSCs). Flow cytometry and immunohistochemistry were used for cell identification. The growth factors were applied at concentrations of 0, 1, 10, and 100 ng/ml as three groups: (1) bFGF alone, (2) EGF alone, and (3) bFGF mixed with EGF. Cell proliferation was evaluated by Cell Counting Kit-8 assays. Expression of Type I and III collagen (Col-I and Col-III) mRNAs was evaluated by real-time quantitative reverse transcription-polymerase chain reaction. Statistical analysis was performed with SPSS software and GraphPad Prism using one-way analysis of variance and multiple t-test.@*Results@#ADSCs were successfully isolated from rat adipose tissue as identified by expression of typical surface markers CD29, CD44, CD90, and CD45 in flow cytometry. Fibroblasts induced from ADSC, compared with ADSCs, were with higher mRNA expression levels of Col I and Col III (F = 1.29, P = 0.0390). bFGF, EGF, and the mixture of bFGF with EGF can enhanced fibroblasts proliferation, and the concentration of 10 ng/ml of the mixture of bFGF with EGF displayed most effectively (all P < 0.05). The expression levels of Col-I and Col-III mRNAs in fibroblasts displayed significant increases in the 10 ng/ml bFGF combined with EGF group (all P < 0.05).@*Conclusions@#The optimal concentration of both bFGF and EGF to promote cell proliferation and collagen expression in fibroblasts was 10 ng/ml at which fibroblasts grew faster and secreted more Type I and III collagens into the extracellular matrix, which might contribute to the stability of the pelvic floor microenvironment.

ABSTRACT
OBJECTIVE:To provide reference for benign sustainable development of traditional Chinese and ethnic medicine enterprises in Guizhou. METHODS:Taking 129 traditional Chinese and ethnic medicine enterprises of 9 city and prefecture in Gui-zhou as survey object,questionnaires survey was conducted in 55 enterprises by stratified sampling according to location. The data statistical analysis was carried out in respects of related policies familiarity,product positioning,independent innovation from 2009 to 2013. Relevant development countermeasures were put forward. RESULTS & CONCLUSIONS:45.1% of enterprises ex-pressed to know and be familiar with relevant policies,51.0% expressed to alert but only understand,and 3.9% said largely un-known. At the past five years,the annual output value and sales revenue of enterprises had risen year by year. Almost 80% produc-tion and technical personnel of enterprises had the junior title or no title;marketing department staff mainly had college and second-ary school degree,accounting for 47.5% and 25.3% respectively;research personnel mainly had bachelor and college degree,ac-counting for 57.0% and 33.7% respectively. At the past five years,independent innovation input took up 2.4% of sales revenue av-eragely. There are problems,such as small and medium enterprises occupying dominate position;enterprises lacking of sufficient understanding on related policies;strategies being adjusted slowly;independent innovation input intensity needing to increase. Countermeasures and suggestions are put forward,such as strengthening the relevant policy advocacy,guiding corporate mergers and acquisitions,closely paying attention to industry development,changing innovation ideas,and attaching importance to research of exclusive production of essential medicine.
ABSTRACT
Objective To establish the finite element model of uterosacral ligament (USL) and cardinal ligament (CL) and analyze the stress distribution and deformation with USL and CL under different working conditions. Methods Patients with stage Ⅲ-Ⅳpelvic organ prolapse (POP) and healthy female volunteers were selected for research subject, and divided into anterior uterus group and posterior uterus group. Two POP patients and two volunteers were selectd into the anterior uterus group and posterior uterine group respectively. Pelvic MRI scan was performed in two groups. Based on the original MRI data sets, the finite element model of USL and CL was constructed by using the software such as the Mimics, and the stress distribution and deformation of USL and CL were simulated. Results Under the premise of the elastic modulus fixed and three different working conditions such as 60 cmH2O, 99 cmH2O and 168 cmH2O (1 cmH2O=0.098 kPa) with abdominal pressure generated by maximum Valsalva maneuver, according to the present conditions and the simulation, the trend was analyzed: the stress and deformation of the uterus, anterior vaginal wall, USL and CL in two groups were mainly distributed in the middle and lower part of the anterior vaginal wall or the ligament and the cervix-vagina junction, the maximum stress and the maximum displacement were mainly concentrated in the lower region of the anterior vaginal wall. With increasing of abdominal pressure generated by the maximum Valsalva maneuver, the maximum stress values of the POP patient in anterior uterus group under three different working conditions were: 0.027 9, 0.046 0, 0.078 0 MPa, and the maximum displacement values were: 9.145 5, 15.090 0, 25.607 0 mm. The maximum stress values of the volunteer in anterior uterus group under three different working conditions were:0.012 6, 0.020 8, 0.035 3 MPa, and the maximum displacement values were: 1.816 7, 2.997 5, 5.086 7 mm. The maximum stress values of the POP patient in posterior uterine group under three different conditions were: 0.069 4, 0.114 6, 0.194 5 MPa, and the maximum displacement values were:11.658 0, 19.236 0, 32.643 0 mm. The maximum stress values of the volunteer in posterior uterus group under three different working conditions were:0.009 1, 0.015 1, 0.025 6 MPa, and the maximum displacement values were:2.581 6, 4.259 6, 7.228 4 mm. The maximum stress values and the maximum displacement values were all increased with increasing of abdominal pressure in the two groups. The maximum stress values and the maximum displacement values of the POP patients were greater than those of volunteers. Under different working conditions, the maximum stress values and maximum displacement values of the posterior uterus POP patient were all greater than those of the anterior uterus POP patient. Conclusions The finite element model of USL and CL is completely based on the MRI technology and the model is real and reliable. The increase of abdominal pressure will produce a larger stress and deformation of USL and CL, which is one of the reasons causing the injury of the ligament.
ABSTRACT
<p><b>PURPOSE</b>For penetrating thoracic trauma, there is no consensus on whether operative exploration or conservative treatment is better. In this study, we compared the clinical effect of video-assisted thoracoscopic surgery (VATS) and thoracotomy on the patients with penetrating thoracic trauma.</p><p><b>METHODS</b>From January 2000 to December 2010, 123 patients with penetrating thoracic trauma were treated in Affiliated Hospital of Chengdu University. Based on the inclusion criteria, 80 patients were enrolled and randomly assigned into VATS and thoracotomy group.</p><p><b>RESULTS</b>The operation time, amount of bleeding and drainage in VATS group were all lower than traditional operation (p < 0.05).</p><p><b>CONCLUSION</b>The results indicate that VATS has the merits of shorter operation time, non-blind area, exact surgical path and less bleeding comparing with traditional operation.</p>
