OBJECTIVE To investigate the distribution and drug resistance of pathogenic bacteria in septicemia in order to provide the reference for clinical antimicrobial agents usage.METHODS The blood samples of inpatients were cultured with blood culture apparatus,VITEK-AMS was used to identify the bacteria and conduct drug resistance test and ESBLs produced by Escherichia coli,and Klebsiella were detected by disc diffusion confirmatory test.RESULTS The 221 strains of pathogens that caused septicemia were mainly distributed in ICU,blood department and infection department.The 61 strains of E.coli were isolated,among which ESBLs were detected and accounted for 39.3%(24),26 strains of Klebsiella were isolated,among which ESBLs were detected and accounted for 26.9%(7),ESBLs strains were more resistant than ESBLs negative strains.Thirty two strains of Staphylococcus were isolated,among which MRS were detected and accounted for 62.5%(20).The pathogens showed highly multiple drug-resistance.Vancomycin and imipenem were the highest susceptible for Gram-positive and Gram-negative bacteria,respectively.CONCLUSIONS The pathogens that caused septicemia are mainly distributed in ICU,blood department and infection department.The situation of antibiotic resistance of pathogens is very serious now.Therefore,it is important to prevent the septicemia and to detect enzyme producing strains regularly for reference of reasonable antibiotic use.

OBJECTIVE To study the change and significance of TNF-? and IL-18 in the Acinetobacter baumannii sepsis. METHODS Sixty male SD rats were divided into 6 groups. The first group was normal control group. The second to sixth groups were sepsis groups which were killed at 4h,16h,24h,48h,72h after injecting A. baumannii through intraperitoneal injection to make sepsis model. The level of TNF-? and IL-18 in the serum of rats was measured by enzyme linked immunosorbent assay (ELISA). RESULTS The level of TNF-? in the serum increased markedly in the sepsis groups (P

In this paper,to evaluate the existence and extent of MRI artifacts caused by frequently used metallic dental materials and to compare the influence of different MRI sequences on artifacts. The artifact of Au-Pt-Pd alloy crown were the smallest and Au-Ag-Pd alloy crown, pure Titanium crown were smaller. But the artifact of Ni-Gr alloy crown were the largest.With the same scan sequences, the different metal materials can make different effects on MRI images with the different scan sequences, the MRI artifact is not obvious caused by the same metal materials. Artifacts produced by oral metallic materials related closely to the type of the materials.The high quality MRI can be gained by choosing proper metallic materials.

Objective To investigate the impact of hepatitis B virus (HBV) infection on semen parameters,sperm DNA integrity,acrosin activity and sperm-nucleoprotein transition.Methods Semen samples from 527 subjects including 273 hepatitis B surface antigen (HBsAg) positive and 254 HBsAg negative,who sought medical attention and received in-vitro feritilization in reproductive medicine center of First Hospital of Wenzhou Medical University from Jan 2011 to Oct 2012 were collected.Semen parameters,sperm DNA fragmentation index (DFI),sperm-nucleoprotein transition and acrosin activity of both HBsAg-positive and HBsAg-negative subjects were analyzed.Results Semen parameters of both groups were within the normal range,but sperm concentration and percentage of forward moving sperms of HBsAg positive group were significantly lower than those of HBsAg negative group (P=0.000),while percentage of static sperms of HBsAg positive group were significantly higher than that of HBsAg negative group (P =0.000).DFI in HBsAg positive and negative group were (17.85 ± 0.70) ％ and (11.85 ± 0.50) ％,respectively,which was significantly different (t=6.951,P=0.000).Percentage of sperms with normal morphology in both groups were within the normal range,but sperms with neck and tail deformity in the HBsAg positive group was significantly higer than those in HBsAg negative group (all P＜0.05).Acrosin activity of sperms in HBsAg positive group was significantly lower than that in HBsAg negative group (t=3.756,P=0.000).Linear regression analysis indicated that serum HBsAg level was reversely correlated with sperm concentration (r=-0.140,P =0.021),but positively correlated to DFI (r =0.151,P =0.014).Conclusions HBV infection not only affects the routine semen parameters and sperm morphology,but also compromises sperm function including impaired DFI and acrosin activity.However,the impact of anti-HBV agents on sperm quality and male fertility requires further research.

Objective To explore the impact of healthcare-associated septicemia (HAS)on hospitalization expense as well as length of hospital stay,so as to optimize the allocation of healthcare resources,and provide scientific basis for reducing the economic burden caused by septicemia.Methods Hospitalized patients with confirmed HAS in a tertiary first-class teaching hospital between June 1 ,2012 and May 31 ,2015 were investigated retrospectively,con-trol group was set up in a 1 :1 ratio,hospitalization expense and length of hospital stay between two groups were compared.Results A total of 285 cases and 285 controls were enrolled in the study,the median of hospitalization expense in case group was higher than control group (￥19 718.39 vs ￥9 289.04,P <0.05);the median of length of hospital stay in case group was longer than control group (14.89 days vs 9.22 days,P <0.05).The disease bur-den caused by septicemia in different age groups and departments were different.The improvement rate of case group was lower than control group (76.49% [218/285 ]vs 83.51 % [238/285 ],χ2 = 2.562,P = 0.009 ). Conclusion As the common blood stream infection in hospitalized patients,septicemia not only increased the ex-pense of diagnosis and treatment,but also affected turnover rate of hospital bed.Rapid and effective diagnosis and treatment is significant o prevent and control septicemia.

Objective: To evaluate the clinical efficacy of two different digestive tract reconstruction methods in the Siewert Ⅱ or Ⅲ adenocarcinoma of esophagogastric junction underwent proximal gastrectomy and piggyback jejunal interposition. Methods: A total of 84 patients with Siewert Ⅱ or Ⅲ AEG who underwent proximal gastrectomy and interposition jejunal anastomosis were enrolled prospectively according to the exclusion criteria, from October 2015 to August 2017 at Department of Digestive Minimally Invasive Surgery, Shanxi Cancer Hospital. There were 61 male and 23 female patients, aged 48-69 years with an average age of 59.7 years. They were divided into single-tract reconstruction group (n=41) and double-tract reconstruction group (n=43) according to random number table. Both groups underwent proximal gastrectomy and piggyback jejunal interposition. After side-to-side anastomosis of the remnant stomach and jejunum was performed in the single-tract group, jejunum 3 cm below the anastomosis was ligated or closed. The jejunum in the double-tract group was not treated during the operation. Relevant nutritional indicators were collected at 3 months and 6 months after operation. The data were analyzed by repeated measurement of variance analysis to determine the nutritional status. Results: There was no significant difference in preoperative general condition between single-tract reconstruction group and double-tract reconstruction group (P>0.05). There was no significant difference in perioperative related indicators (P>0.05). Nutritional indicators in single-channel reconstruction group were higher than those in double-channel reconstruction group (hemoglobin: F=23.374, P=0.000; albumin: F=6.149, P=0.003; total protein: F=18.362, P=0.000; weight: F=74.255, P=0.000). The quality of life was compared half year after operation, there was no significant difference in the incidence of subjective symptoms such as reflux, heart burning, nausea and vomiting, dysphagia and sternum discomfort in the two groups (P>0.05), as well as the results of QLQ-STO22 score (27.0±3.8 vs. 27.6±3.3, t=-0.688, P=0.494). The results of gastroscopy showed that the incidence and degree of the two groups were almost the same whether in the incidence of reflux esophagitis (2/41 vs. 2/43, P=1) or in the contrast of reflux degree (Z=-1.528, P=0.127). Conclusion For patients with type Siewert Ⅱ or Ⅲ esophagogastric junction adenocarcinoma who underwent proximal gastrectomy and piggyback jejunal operation, single tract reconstruction is ideal.

Objective:To investigate the application value of self-pulling and latter transection (SPLT) technique in double anti-reflux double-tract reconstruction of totally laparoscopic proximal gastrectomy.Methods:The retrospective cohort study was conducted. The clinicopatholo-gical data of 103 patients with Siewert type Ⅱ adenocarcinoma of esophagogastric junction in clinical stage Ⅰ-Ⅱ who were admitted to Shanxi Cancer Hospital from January 2018 to January 2020 were collected. There were 65 males and 38 females, aged from 45 to 79 years, with a median age of 59 years. Of 103 patients, 49 cases undergoing totally laparoscopic proximal gastrectomy with double-tract reconstruction of SPLT were assigned into the SPLT group, 54 cases undergoing totally laparoscopic proximal gastrectomy with conventional double-tract reconstruction were assigned into the traditional group. Observation indicators: (1) intraoperative situations; (2) postoperative situations; (3) follow-up. Follow-up was conducted by outpatient examination and telephone inter-view to detect postoperative reflux esophagitis of patients up to December 2021. Measurement data with normal distribution were represented as Mean± SD, and the t test was used for comparison between groups. Measurement data with skewed distribution were represented as M(range) or M( Q1, Q3), and the Wilcoxon test was used for comparison between groups. Count data were described as absolute numbers or percentages, and comparison between groups was performed using the chi-square test. Comparison of ordinal data was analyzed using the non-parameter rank sum test. Results:(1) Intraoperative situations: the operation time, digestive tract reconstruction time, volume of intraoperative blood loss, the number of inferior mediastinal lymph nodes dissected, cases with auxiliary incisions for the SPLT group were (261±48)minutes, (26±4)minutes, (114±42)mL, 8.0(6.5,9.5), 1, respectively. The above indicators were (244±42)minutes, (30±6)minutes, (118±46)mL, 5.5(4.0,8.0), 9 for the traditional group, respectively. There were significant differences in the digestive tract reconstruction time, the number of inferior mediastinal lymph nodes dissected and cases with auxiliary incisions between the two groups ( t=-3.34, Z=-4.05, χ2=4.72, P<0.05). There was no significant difference in the operation time or volume of intraoperative blood loss between the two groups ( t=1.87, -0.47, P>0.05). (2) Postoperative situations: duration of postopera-tive hospital stay and cases with postoperative complications were (11.5±2.7)days and 4 for the SPLT group, versus (12.5±4.3)days and 9 for the traditional group, showing no significant difference between the two groups ( t=-1.47, χ2=1.68, P>0.05). There were 13 of 103 patients with postopera-tive complications, including 5 cases of left pleural effusion, 4 cases of anastomotic leakage, 2 cases of mild pneumonia, 1 case of incision infection, 1 case of chylous leakage. Four patients had anasto-motic leakage at the esophagojejunostomy, the abdominal esophagus of whom was invaded by more than 1 cm. During the operation, mediastinal drainage tubes were placed through the abdominal wall. The 4 patients were cured after enteral and parenteral nutrition support and adequate drainage, and the remaining patients with complications were cured after symptomatic treatment. (3) Follow-up: of 49 patients in the SPLT group, 43 cases were followed up for (18±4)months. During the follow-up, 1 case showed reflux esophagitis by gastroscopy, with the incidence of 2.33%(1/43). Of 54 patients in the traditional group, 53 cases were followed up for (17±4)months. During the follow-up, 4 cases showed reflux esophagitis by gastroscopy, with the incidence of 7.55%(4/53). There was no significant difference in the incidence of reflux esophagitis between the two groups ( χ2=0.47, P>0.05). Conclusions:SPLT technology is feasible for double anti-reflux double-tract reconstruction of proximal gastrectomy. Compared with traditional double-tract reconstruction of totally laparos-copic proximal gastrectomy, SPLT technology can reduce the auxiliary incisions, increase the number of lower mediastinal lymph nodes dissected, and shorten the digestive tract reconstruction time.

The global COVID-19 coronavirus pandemic has infected over 109 million people, leading to over 2 million deaths up to date and still lacking of effective drugs for patient treatment. Here, we screened about 1.8 million small molecules against the main protease (M^pro) and papain like protease (PL^pro), two major proteases in severe acute respiratory syndrome-coronavirus 2 genome, and identified 1851M^pro inhibitors and 205 PL^pro inhibitors with low nmol/l activity of the best hits. Among these inhibitors, eight small molecules showed dual inhibition effects on both M^pro and PL^pro, exhibiting potential as better candidates for COVID-19 treatment. The best inhibitors of each protease were tested in antiviral assay, with over 40% of M^pro inhibitors and over 20% of PL^pro inhibitors showing high potency in viral inhibition with low cytotoxicity. The X-ray crystal structure of SARS-CoV-2 M^pro in complex with its potent inhibitor 4a was determined at 1.8 Å resolution. Together with docking assays, our results provide a comprehensive resource for future research on anti-SARS-CoV-2 drug development.
