Objective:To investigate the clinical value of cephalosporin combined with morinidazole in the prevention of surgical site infection (SSI) for gastrointestinal fistula.Methods:The retrospective cohort study was conducted. The clinicopathological data of 107 patients with gastrointestinal fistula who undergoing selective digestive tract reconstruction surgery in General Hospital of Eastern Theater Command from January to December 2017 were collected. There were 76 males and 31 females, aged from 18 to 79 years, with a median age of 46 years. Of 107 patients, 43 cases receiving cephalosporin for prevention of SSI were allocated into cephalosporin monotherapy group, 64 cases receiving cephalosporin combined with morinidazole were allocated into combination therapy group, respectively. Observation indicators: (1) incidence of SSI; (2) stratification; (3) pathogen culture results of SSI; (4) adverse drug reaction; (5) follow-up. Follow-up using outpatient examination and telephone interview was performed to detect other complications of patients. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the independent sample t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was analyzed using the Mann-Whitney U test. Count data were described as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test or Fisher exact probability. Results:(1) Incidence of SSI: 29 of 107 patients had postoperative SSI, including 15 cases with superficial SSI, 7 cases with deep SSI, and 7 cases with organ/space SSI. There were 18 cases of cephalosporin monotherapy group with SSI, including 7 cases with superficial SSI, 5 cases with deep SSI, and 6 cases with organ/space SSI. The above indicators were 11, 8, 2, 1 of combination therapy group, respectively. There was a significant difference in the overall SSI between the two groups ( χ2=7.925, P<0.05). There was also a significant difference in the organ/space SSI between the two groups ( P<0.05). There was no significant difference in the superficial SSI between the two groups ( χ2=0.305, P>0.05). There was no significant difference in the deep SSI between the two groups ( P>0.05). (2) Stratification: there were 10 cases and 33 cases with type Ⅱ incision and type Ⅲ incision in the 43 cases of cephalosporin monotherapy therapy group, respectively. The above indicators were 11 and 53 in the combination group, respectively. For the type Ⅱ incision, 1 patient of cephalosporin monotherapy group had SSI, and 2 cases of combination therapy group had SSI, showing no significant difference between the two groups ( P>0.05). For the type Ⅲ incision, 17 patient of cephalosporin monotherapy group had SSI, and 9 cases of combina-tion therapy group had SSI, showing a significant difference between the two groups ( χ2=11.499, P<0.05). (3) Pathogen culture results of SSI: of 29 patients with SSI, 21 were positive for bacterial culture, including 12 cases with single bacterial infection, 9 cases with mixed infection of multi-bacteria. A total of 33 strains were cultured. (4) Adverse drug reaction: there was no adverse drug reaction in the 107 patients. (5) Follow-up: 107 patients were followed up for 30 days after surgery. No complication occurred in the 107 patients. Conclusion:Cephalosporin combined with morini-dazole can be used to prevent the SSI for patients with gastrointestinal fistula.

Objective:To investigate the safety and feasibility of transgluteal percutaneous drainage using double catheterization cannula in the treatment of deep pelvic abscess.Methods:A retrospective analysis of the clinical data of patients who underwent transgluteal percutaneous drainage using double catheterization cannula with deep pelvic abscesses admitted to the Jinling Hospital from May 2017 to September 2020 was conducted. Seven patients were enrolled, including 5 males and 2 females, who aged 26-74 (median 53.0) years old, and all of them had digestive fistula. One male patient was punctured again due to the tube falling off, and a total of 7 patients underwent 8 times of transgluteal percutaneous drainage, all under the guidance of CT. The puncture and drainage steps of the double catheterization cannula group are as follows: (1) Locate the puncture point under CT in the lateral position; (2) Place the trocar into the abscess cavity; (3) Confirm that the trocar is located in the abscess cavity under CT; (4) Pull out the inner core and insert into the double catheterization cannula through the operating hole; (5) Confirmthat the double catheterization cannula is located in the abscess cavity under CT; (6) The double catheterization cannula is properly fixed to prevent it from falling off. The white blood cells, C-reactive protein (CRP), procalcitonin, and interleukin-6 (IL-6) of all patients before the drainage and 1 days, 3 days, and 5 days after the drainage were collected, as well as the bacterial culture results of the drainage fluid. The changes of various infection biomarkers before and after the drainage were compared.Results:All 7 patients were cured. No complications such as hemorrhage and severe pain were observed. The average time with drainage tube was 60.8 (18-126) days. Five patients finally underwent gastrointestinal reconstruction surgery due to gastrointestinal fistula. The median serum interleukin-6 of patients before drainage, 1 day, 3 days and 5 days after drainage were 181.6 (113.0, 405.4) μg/L, 122.2 (55.8, 226.0) μg/L, 59.2 (29.0,203.5) μg/L and 64.1 (30.0,88.4) μg/L, respectively.The level of serum interleukin-6 at 3 days and 5 days after drainage was significantly lower than before drainage ( F=3.586, P=0.026). Although the white blood cell count, C-reactive protein, and procalcitonin decreased gradually after drainage compared with before drainage, the difference was not statistically significant (all P>0.05). Conclusion:Transgluteal percutaneous drainage with double catheterization cannula is simple and effective, and can be used for the treatment of deep pelvic abscess.

Objective: To investigate the effects of andrographolide on extracellular signal-regulated kinase 1/2 (ERK1/2) signaling pathway and tumor necrosis factor-α (TNF-α) expression in lipopolysaccharide (LPS)-activated macrophages. Methods: LPS-activated mouse peritoneal macrophages were cultured in media with different concentrations of andrographolide. Cytotoxicity of andrographolide was detected by cell counting kit-8. The macrophages were lysed, and then expressions of phosphorylated ERK1/2, JNK and p38 and nuclear factor-κB inhibitor (IκBα) protein were detected by Western blotting and TNF-α mRNA expression was detected by reverse transcription-polymerase chain reaction. Supernatants of the macrophages were used to detect content of TNF-α protein by enzyme-linked immunosorbent assay. Results: Andrographolide at 1-100 μg/mL showed no cytotoxicity on LPS-activated mouse peritoneal macrophages. Andrographolide inhibited ERK1/2 phosphorylation in LPS-activated murine peritoneal macrophages, which was concentration-dependent (P<0.01). Andrographolide at 1-25 μg/mL had no effects on phosphorylation levels of JNK and p38 and IκBα degradation in LPS-stimulated mouse peritoneal macrophages. In activated macrophages, TNF-α expression was inhibited by 12 μg/mL andrographolide and 20 μmol/L PD98059 (inhibitor of ERK1/2 signaling pathway) at both mRNA expression and protein secretion levels. Conclusion: In LPS-activated macrophages, andrographolide may inhibit the expression of TNF-α by inhibiting ERK1/2 signaling pathway.
