Objective To study the susceptibility of Neisseria gonorrhoeae to antibiotic agents from 1988 to 2002 in Shanghai. Methods The clinical isolates from patients with gonorrhea were collected and tested for their susceptibility to five antibiotics. Agarose-dilution-method was used to detect minimal inhibitory concentration (MIC) of anti-microbial agents including penicillin, tetracycline, spectinomycin, ciprofloxacin and ceftriaxone, and penicillinase producing Neisseria gonorrhoeae (PPNG) were tested with acidometric method. Results Susceptible strains to penicillin decreased from 11.28% in 1988 to 0 in 2002, MIC50 and MIC90 increased 8 and 4 times, respectively, the resistant rate and proportion of PPNG were 94.29% and 50.95%, respectively in 2002. The strains of high resistance to tetracycline increased from 0 in 1995 to 20.95% in 2002. The susceptible strains to ceftriaxone decreased from 100% in 1995 to 23.80% in 2002. The susceptibility to ciprofloxacin decreased significantly and resistant rate reached 99.05% in 2002. However, these strains were kept highly susceptible to spectionmycin. Concerning the multi-drug resistance, we found that the strains resistant to penicillin, ciprofloxacin and tetracycline simultaneously increased from 20.87% in 2001 to 23.30% in 2002, those resistant to both penicillin and ciprofloxacin reached to 70% in the past 2 years. Conclusions In Shanghai the resistant rates of Neisseria gonorrhoeae to antibiotics increased year by year in the past 15 years. The study indicates that spectinomycin and ceftriaxone should be the first choice for the treatment of gonorrhea at present and new sensitive antibiotic should be developed for the treatment of gonorrhea.

OBJECTIVETo observe effect of oral scorpio and scolopendra powder on T-cell subsets in peripheral blood and intestine from rats with collagen induced arthritis (CIA).

METHOD60 rats were randomly divided into 6 groups: normal control group, model control group, low-dose scorpio and scolopendra group, middle-dose scorpio and scolopendra group, high-dose scorpio and scolopendra group, and type II collagen group. Rat's rheumatoid arthritis was induced by collagen II (C II). Level of T-cell subsets from peripheral blood and intestine was measured by flow cytometry.

RESULTCD4+ T cellular level was obviously increased (P < 0.05 or P < 0.01) or kept increased tendency in peripheral blood and intestine from the model group compared with that of the normal group, while the ratio of CD4+/CD8+ in intestine was obviously descent but the contrary in peripheral blood (P < 0.05 or P < 0.01). CD4+, CD8+ T cellular level in intestine were obviously descent and the ratio of CD4+ /CD8+ increased in all treated groups when compared with in the model group (P < 0.05 or P < 0.01). However, CD4+ T cellular level and the ratio of CD4+/CD8+ in peripheral blood were remarkablely decreased.

CONCLUSIONThe mechanism that scorpio and scolopendra could treat rat's rheumatoid arthritis may be regulating balance of T-lymphocyte subsets in peripheral blood and intestine.

Objective To analyze the serotypes and antimicrobial susceptibility profile of Group B Streptococcus (GBS) in perinatal pregnant women.Methods The vaginal and rectal specimens were collected from pregnant women at 35 to 37 weeks of pregnancy for culture and identification.The serotypes were analyzed using agglutination assay.Antimicrobial susceptibility testing was conducted by using Kirby-Bauer method,and interpreted according to 2009 CLSI breakpoints.The data were analyzed via WHONET 5.6 software.Results The prevalence of GBS was 10.4％ (264/2 533) in the 2 533 perinatal pregnant women.Serotype Ⅲ,Ⅰa and Ⅰb was identified in 54.9％ (84/153),17.6％ (27/153) and 13.1％ (20/153) of the GBS,respectively.All the GBS isolates were susceptible to penicillin,cefiriaxone and vancomycin.But 32.9％,68.1％ and 62.1％ of the isolates were resistant to levofloxacin,erythromycin and clindamycin,respectively.The antibiotic resistance rate of serotype Ⅲ isolates to the above three antibiotics was significantly higher than the other serotypes.Conclusions GBS may colonize both vagina and rectum of pregnant women.Vaginal and rectal secretions should be sampled simultaneously for better screening GBS.GBS serotype Ⅲ was the predominant serotype.Penicillin can be used as the first-choice treatment for GBS infections in pregnant women and newborns.GBS-positive pregnant women should be given the intervention treatment immediately to ensure the health of perinatal infants.

ObjectiveTo investigate the association of high-density lipoprotein cholesterol (HDL-C) with the prognosis of patients with alcohol-related hepatocellular carcinoma (HCC) after radical treatment. MethodsA retrospective analysis was performed for the clinical data of 43 patients with alcohol-related HCC who were admitted to The Fifth Medical Center of Chinese PLA General Hospital and underwent radical treatment from January 2008 to July 2015, and according to HDL-C level, the patients were divided into normal group with 26 patients and abnormal group with 17 patients. The two groups were compared in terms of basic information, laboratory markers, imaging indices, Barcelona Clinic Liver Cancer tumor stage, and Child-Pugh class of liver function. The t-test test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test was used for comparison of categorical data between two groups. The Kaplan-Meier method was used to plot survival curves and the log-rank test was used for comparison between groups. Univariate and multivariate Cox proportional hazards models were used to analyze independent risk factors for prognosis. ResultsThere was a significant difference in prealbumin between the two groups (162.38±60.86 mg/L vs 120.06±64.08 mg/L, t=2.184, P=0.035). Number of tumors (hazard ratio ［HR］=2.839, 95%confidence interval ［CI］: 1.120~7.200,P=0.028), tumor size (HR=2.634, 95%CI: 1.062~6.529,P=0037), and HDL-C level (HR=2.400, 95%CI: 1.040~5.537,P=0.040) were independent risk factors for the overall survival of patients with alcohol-related HCC. There were significant differences in 1-, 3-, and 5-year cumulative survival rates between the normal group and the abnormal group (88.5%/72.4%/55.7% vs 70.6%/43.7%/17.5%, χ2=5.881, P=0.015). ConclusionThe reduction in HDL-C level might indicate poor prognosis of patients with alcohol-related HCC.

Objective:To investigate the clinical efficacy of wrist arthroscopic transosseous footprint repair technique for treating triangular fibrocartilage complex (TFCC) injury.Methods:A retrospective case series study was conducted to analyze the clinical data of 56 patients with TFCC injury admitted to Shenzhen Second People′s Hospital from July 2017 to September 2020, including 38 males and 18 females, aged 17-45 years [(33.5±3.6)years]. All patients had unilateral injury. Physical examination showed instability of the distal radioulnar joint, and MRI and arthroscopy confirmed deep ligament injury of TFCC. All patients underwent repair of deep insertion of the TFCC by using wrist arthroscopic transosseous footprint. The operation time, intraoperative blood loss, wound healing and postoperative complications were recorded. The flexion and extension range of motion of the wrist, radial and ulnal deviation of the wrist, rotation range of motion of the forearm, patient related wrist evaluation (PRWE) score, modified Mayo wrist score, visual analogue scale (VAS), and percentage of grip strength between the affected side and unaffected side were compared preoperatively, at 3 months postoperatively and at 1 year postoperatively.Results:All patients were followed up for 12-18 months [(13.4±5.2)months]. The operation time was (61.3±8.9)minutes, with the intraoperative blood loss of (2.4±1.2)ml. All wounds were healed by first intension. There was no wound infection or ulnar nerve irritation symptom after operation. Four patients experienced clicking on the ulnar side of the wrist in a short period of time post-operation, with spontaneous disappearance of the symptom. At 3 months postoperatively, the radial and ulnar deviation of the wrist was decreased from (52.5±5.9)° preoperatively to (42.6±5.9)°, and rotation range of motion of the forearm was decreased from (94.9±8.4)°preoperatively to (84.6±5.9)° (all P<0.01). The flexion and extension range of motion of the wrist was (93.1±17.4)° preoperatively, with insignificant difference compared with (89.4±5.8)° at 3 months postoperatively ( P>0.05). At 1 year postoperatively, the flexion and extension range of motion of the wrist, radial and ulnar deviation range of motion of the wrist, and rotation range of motion of the forearm were significantly increased to (101.3±13.6)°, (52.4±6.6)°, and (116.4±16.4)° when compared with those at 3 months postoperatively (all P<0.01). At 3 months postoperatively, the PRWE score was increased to (17.1±3.8)points from (10.6±3.2)points preoperatively ( P<0.01), modified Mayo wrist score was decreased to (70.3±6.7) points from (78.1±12.7)points preoperatively ( P<0.01), VAS was decreased to (4.4±1.7)points from (6.2±1.5)points preoperatively ( P>0.05), and percentage of grip strength between the affected side and unaffected side was decreased to (55.7±8.7)% from (74.4±15.2)% preoperatively ( P<0.01). At 1 year postoperatively, the PRWE score was increased to (2.0±0.9)points, modified Mayo wrist score was increased to (94.8±3.3)points, VAS was decreased to (2.1±1.1)points, and percentage of grip strength between the affected side and unaffected side was increased to (93.2±8.7)% when compared with those at 3 months postoperatively (all P<0.01). Conclusion:Wrist arthroscopic transosseous footprint repair technique can effectively treat deep ligament injury of TFCC, with advantages of significantly improving postoperative joint range of motion and functional score, relieving the pain on the ulnar side of the wrist and enhancing grip strength.

Objective:To explore the relationship between fragmented QRS complex and heart rate variability (HRV) and ventricular arrhythmia in patients with old myocardial infarction.Methods:From August 2018 to October 2019, 200 patients with old myocardial infarction were first treated in the Department of cardiac function examination of the First Affiliated Hospital of Hebei North University. The patients were divided into 99 cases of old myocardial infarction with fragmented QRS wave group and 101 cases of old myocardial infarction without fragmented QRS wave group according to the case bank data and conventional 12 lead ECG diagnosis in our hospital for the first time. Then, the 24-h ambulatory ECG reexamined within 1 year after discharge was retrospectively analyzed. The incidence of ventricular arrhythmia was compared between the two groups by χ 2 test. The difference of heart rate variability between the two groups was compared by rank sum test. Multiple logistic regression was used to analyze the value of different indexes of heart rate variability in the evaluation of fragmented QRS complex in old myocardial infarction. Drawing the receiver operating characteristic (ROC), and the area under the curve (AUC) was used to analyze the diagnostic accuracy of different indexes of heart rate variability in the broken QRS complex of old myocardial infarction. Results:According to the Lown classification of ventricular premature contraction, the number of positive ventricular arrhythmias in patients with Grade Ⅰ of ventricular premature contraction and Grade Ⅲ-Ⅴ of ventricular premature contraction in the old myocardial infarction fragmented QRS group was higher than that in the old myocardial infarction non fragmented QRS group (Grade Ⅰ of ventricular premature contraction: 54.5% (54/99)and 39.6%(40/101); χ 2=4.484, P<0.05;Grade Ⅲ-Ⅴ of ventricular premature contraction: 34.3% (34/99) and 9.9%(10/101); χ 2=17.406, P<0.05)). Ventricular premature contraction Grade 0 old myocardial infarction fragmented QRS group was lower than old myocardial infarction non fragmented QRS group (8.1% (8/99) and 48.5% (49/101); χ 2=37.995, P<0.05). The total number of positive cases of ventricular arrhythmia in the old myocardial infarction group with fragmented QRS wave was higher than that in the old myocardial infarction group without fragmented QRS wave (91.9% (91/99) and 51.5%(52/101); χ 2=57.146, P<0.05)). There was no significant difference in the number of positive ventricular arrhythmias between the old myocardial infarction fragmentation QRS group and the old myocardial infarction non fragmentation QRS group ( P>0.05). The standard deviation of NN intervals (SDNN) and the standard deviation of average NN intervals (SDANN) of HRV time domain indexes in the old myocardial infarction fragmented QRS group were higher than those in the old myocardial infarction non fragmented QRS Group (SDNN:143.00(122.00,166.00) vs. 110.00(95.00,130.50), Z=5.780, P<0.05; SDANN:112.00(100.00,136.00) vs. 96.00(76.00,118.50), Z=4.013, P<0.05). Multiple Logistics regression analysis results of HRV domain shows that HRV time domain SDNN and SDANN have diagnositic value in diagnosis fQRS after OMI(SDNN: OR=0.949, 95% CI:0.922-0.977, P<0.001; SDANN: OR=1.036, 95% CI:1.005-1.068, P=0.022). Area under ROC curve of HRV time domain SDNN and SDANN have particular diagnositic accuracy in diagnosis fQRS after OMI(SDNN: AUC 0.737, 95% CI 0.666-0.807, Sensitivity 0.818, Specificity 0.634; SDANN: AUC 0.664, 95% CI 0.587-0.741, Sensitivity 0.737, Specificity 0.673. 0.5
