ObjectiveTo investigate the therapeutic efficacy， influencing factors， and safety of a treatment regimen based on coblopasvir hydrochloride capsules/sofosbuvir tablets in patients with chronic hepatitis C virus （HCV） infection in a real-world setting. MethodsA total of 253 patients who attended The Third People’s Hospital of Kunming from September 1， 2021 to May 31， 2024 were enrolled， among whom there were 86 patients with compensated liver cirrhosis （CLC group） and 167 patients with chronic hepatitis C （CHC group）. The patients were treated with coblopasvir hydrochloride capsules （60 mg）/sofosbuvir tablets （400 mg） with or without ribavirin tablets for 12 weeks， and they were followed up for 12 weeks after drug withdrawal. The primary outcome measures were the rate of sustained virologic response at week 12 after treatment （SVR12） and safety， and the secondary outcome measures were the changes in liver function， renal function， blood routine， and liver stiffness measurements （LSM） after 4 weeks of treatment， after 12 weeks of treatment， and at 12 weeks after drug withdrawal. The independent-samples t test and the Mann-Whitney U test were used for comparison of continuous data between two groups， and the Friedman test was used for comparison between multiple groups， while the Bonferroni method was used for paired comparison within each group； the chi-square test was used for comparison of categorical data between two groups. The Logistic analysis was used to investigate related influencing factors. ResultsThe 253 patients with chronic HCV infection had a mean age of 49.38±8.65 years， and there were 151 male patients （59.7%）. Of all patients， 33.99% （86/253） had liver cirrhosis， 25.69% （65/253） had hypertension， 10.67% （27/253） had HIV infection， 8.70% （22/253） had diabetes， 3.95% （10/253） had liver cancer， 1.98% （5/253） had chronic hepatitis B， and 7.91% （20/253） were treatment-experienced patients. As for genotype distribution， 2.77% （7/253） had genotype 1， 12.65% （32/253） had genotype 2， 66.01% （167/253） had genotype 3， 16.60% （42/253） had genotype 6， and 1.98% （5/253） had unknown genotype. The patients had an overall SVR12 rate of 92.09%， with an SVR12 rate of 93.02% in the CLC group and 91.02% in the CHC group. The multivariate logistic regression analysis showed that age （odds ratio ［OR］=1.086， 95% confidence interval ［CI］： 1.007 — 1.170， P=0.032） and HCC （OR=9.178， 95%CI： 1.722 — 48.912， P=0.009） were independent influencing factors for sustained virologic response. Compared with baseline data， the CLC group had significant reductions in alanine aminotransferase （ALT） （χ²=107.103， P0.05）， aspartate aminotransferase （AST） （χ²=90.602， P0.05）， and LSM （χ²=42.235， P0.05） after 12 weeks of treatment， while the CHC group had significant reductions in total bilirubin （χ²=15.113， P0.05）， ALT （χ²=202.237， P0.05）， AST （χ²=161.193， P0.05）， and LSM （χ²=37.606， P0.05）. The incidence rate of serious adverse events was 1.58%， and none of the patients withdrew from drug therapy； the patients with such events were relieved after active symptomatic treatment. The incidence rate of all adverse events was 23.72%， among which fatigue （17.39%） and nausea （2.37%） were the most common adverse events， and these events often disappeared within 2 weeks or were gradually relieved after symptomatic treatment. ConclusionCoblopasvir hydrochloride capsules/sofosbuvir tablets with or without ribavirin tablets has good efficacy and safety in the treatment of chronic HCV infection.

ObjectiveTo study the mechanism of Shenling Guchang prescription on blood glucose of gestational diabetes mellitus rats by regulating intestinal flora and short chain fatty acids. MethodThe 30 pregnant rats were randomly selected from 36 pregnant rats which were successfully pregnant. The model rats were fed with high-fat and high-sugar diet for 1 week， and 35 mg·kg^-1 streptozotocin （ STZ ） was given for 3 consecutive days to construct a gestational diabetes model. After successful modeling， the rats were randomly divided into model group， metformin group， Shenling Guchang prescription low-， medium- and high-dose group. The high dose group of Shenling Guchang prescription was given 18 mg·kg^-1， the middle dose group was given 9 mg·kg^-1， the low dose group was given 4.5 mg·kg^-1 drug solution by gavage， the metformin group was given 52.5 mg·kg^-1 drug solution by gavage， the blank group and the model group were given equal volume of normal saline by gavage.At 24 h after the last administration， blood samples were collected from the tail tip of the rats to measure the blood glucose， and blood samples were collected from the abdominal aorta under anesthesia to measure the levels of triglyceride （TG）， total cholesterol （TC）， high density lipoprotein cholesterol （HDL-C） and low density lipoprotein cholesterol （LDL-C）. Lipopolysaccharides （LPS）， interleukin-1β （IL-1β）， interleukin-6 （IL-6）， tumor necrosis factor-α （TNF-α） and insulin （INS） were detected by enzyme-linked immunosorbent assay （ELISA）.The intestinal tissue of rats was taken， and the pathological changes of intestinal tissue were observed by hematoxylin-eosin （HE） staining. Fecal samples were collected from rats， 16S rRNA sequencing was used to detect intestinal flora， and short-chain fatty acids were detected by gas chromatography. ResultCompared with the blank group， the incidence of adverse pregnancy outcomes in the model group was significantly increased （P<0.05）. Compared with the model group， the incidence of adverse pregnancy outcomes in the Shenling Guchang prescription groups and the metformin group was significantly decreased （P<0.05）. Compared with the blank group， the levels of blood glucose， TG， TC， HDL-C， LDL-C， LPS， IL-1β， IL-6 and TNF-α in the model group were significantly increased （P<0.05）， and the intestinal tissues had different degrees of inflammatory changes and mucosal damage. Compared with the model group， the levels of blood glucose， TG， TC， HDL-C， LDL-C， LPS， IL-1β， IL-6 and TNF-α in each group of Shenling Guchang prescription and metformin group were down-regulated （P<0.05）， and intestinal inflammation and intestinal mucosal damage were improved. Compared with the blank group， the functional structure and diversity of intestinal flora in the model group changed （P<0.05）. Compared with the model group， the functional structure and diversity of intestinal flora in the Shenling Guchang prescription groups and the metformin group were reversed， and the trend was close to the blank group （P<0.05）.Compared with the blank group， the abundance of pathogenic bacteria such as Escherichia coli， Enterococcus， Klebsiella， and Dustella in the model group was significantly increased， and the abundance of probiotics such as Prevotella， Prevotella， Akmania， Rombustella， and Lachnospiraceae was decreased （P<0.05）. Compared with the model group， the abundance of pathogenic bacteria such as Escherichia coli， Enterococcus， Klebsiella， and Dustella was decreased （P<0.05）， and the abundance of probiotic bacteria such as Prevotella， Akmanella， Rombustella， and Lachnospira was increased （P<0.05） in the Shenling Guchang prescription groups and the metformin group. Compared with the blank group， the content of short-chain fatty acids in the model group was significantly decreased （P<0.05）. Compared with the model group， the content of short-chain fatty acids in each group of Shenling Guchang prescription and metformin group increased （P<0.05）. Correlation analysis showed that Proteobacteria was positively correlated with inflammatory factors， blood glucose and blood lipid in gestational diabetes mellitus （P<0.05）. ConclusionShenling Guchang prescription has a good regulatory effect on blood glucose， blood lipids and adverse pregnancy outcomes in rats with gestational diabetes mellitus. Its efficacy is comparable to that of metformin sustained-release tablets. Its mechanism may be related to regulating the structure of intestinal flora， increasing the content of short-chain fatty acids， reducing LPS， IL-1β， IL-6， TNF-α， and improving intestinal inflammation.

Objective To understand characteristics and research status of literatures related to surgical site infec-tion(SSI)in China.Methods Literatures about SSI published between January 2000 and March 2016 were retrieved from China National Knowledge Infrastructure(CNKI),VIP database,Vanfang Database,and China Biology Medi-cine(CBM)database. Bibliometric method was adopted to analyze external and internal characteristics of literatures. Results A total of 1036 articles in Chinese were included,40(3.86% ),189(18.24% ),and 807(77.90% )were published in 2000-2005,2006-2010,and the first quarter of 2011-2016 respectively. Articles were mainly pub-lishedinChineseJournalofNosocomiology(n= 226,21.81% ),ChineseJournalofInfectionControl(n= 53, 5.12% ),andChineseJournalofDisinfection(n= 27,2.61% ). The research fields included risk factors(n= 277, 26.74% ),infection rates (n= 261,25.19% ),antimicrobial application (n= 208,20.08% ),and pathogens (n=153,14.77% );the infection rates were higher in general surgery and neurosurgery,the main pathogens were Esch-erichiacoli,Staphylococcusaureus,and Pseudomonasaeruginosa,risk factors mainly included the types of incision, duration of surgery,diabetes,age,and body mass index.Conclusion In recent years,articles about SSI research in-creases significantly,research in etiology and epidemiology has gained substantial achievement,but in the interven-tion and economics is still weak,suggesting that SSI research in economics,risk management,and behavioral aspects should be strengthened.

Objective To understand the occurrence and risk factors for surgical site infections (SSIs)following appendectomy,so as to provide reference for taking effective prevention measures.Methods Through monitoring on surgical site,SSIs in patients undergoing appendectomy in a hospital from July 1 ,2011 to July 1 ,2013 were inves-tigated.Results A total of 817 appendectomy surgery patients were investigated,37 (4.53%)of whom had SSIs, 36 of which were superficial wound infection,and 1 was deep wound infection.Univariate analysis showed that SSIs were related with duration of operation,anesthesia mode,ASA score,blood sugar,whether perioperative antimi-crobials were used,and operative risk index score(all P <0.05 ).Multivariate logistic regression analysis revealed that blood sugar (OR 95% CI :1 .07-4.72),whether perioperative antimicrobials were used(OR 95% CI :1 .14-7.10),and risk index score (OR 95% CI :5.90-43.28)were independent risk factors for SSIs following appendec-tomy (all P <0.05).Conclusion Surgical site monitoring is helpful for the understanding of SSIs following appen-dectomy;proper intervention measures should be adopted in clinic to prevent SSIs following appendectomy.

Based on a pair of specific primers, a 804-bp fragment was amplified from the plasmid pT-Cap containing Cap gene of Porcine Getah Virus(PGETV) and cloned into the prokaryotic expression vector pCold I which carried the His tag, this recombinant plasmid was then determined by enzyme digestion, PCR and DNA sequencing. This recombinant plasmid pCold-Cap was transformed into E. coli Rosetta 2, and PGETV Cap fusion protein was expressed through IPTG induction. The results showed that the Cap gene obtained efficient and soluble expression in Rosetta 2 induced by 0. Immol/L IPTG under 15"C for 24h, the expression quantity was 40. 2%. The product had a molecular mass about 32. 3kD as expected. The target protein was separated in gel slices and used to immunize Balb/c mice. The polyclonal antibody with high titer against Cap protein specifically analyzed by Western blot was obtained. The successful preparation of the polyclonal antibody laid the foundation for the further study on the detection and identification of PGETV.
