Objective To explore the clinical efficacy of modified single-portlaparoscopic radical prostatec-tomy(LRP) by atransperitoneal or extraperitoneal approach, and the impact of either approach on immune function in patients with prostate neoplasms. Methods The clinical data on 39 patients who had undergoneextraperitoneal LRP(group A) and 20 patients who had receivedtranperitoneal LRP (group B) in our department from January 2012 to December 2015 were retrospectivelyanalyzed. The prostate neoplasms were preoperatively diagnosed as cancer by ultrasound, CT or MRI, and pathological examinations. The clinical stage was T1-T2c , N0M0 in all patients.The efficacy was assessed by surgical duration, intraoperative blood loss, timeto intestinal function recovery, and post-operative hospital stay in both groups. The indicators for immune function including prostate specific antigen (TPSA and FPSA), immunoglobulin (IgG, IgA, lgM, C3, and C4) and T lymphocyte subsets (CD3+, CD4+, CD8+, CD4+/CD8+) in patientswith prostate neoplasms before and after surgery were detected. Results 59 patients were operat-ed successfully, without converting to open approach. The mean surgical duration, blood loss, time to intestinal function recovery, and postoperative hospital stay were (133.8 ± 68.6) min, (75.6 ± 51.3) mL, (2.2 ± 0.7) days, and (14.7 ± 3.6) days in group A, while (159.4 ± 78.1) min, (102.2 ± 70.8) mL, (2.9 ± 1.1) days, and (15.2 ± 4.1) days in group B. There were significant differences between the two groups (P<0.05). After surgery, levels of IgG, IgA, C3, C4, CD3+, CD4+and CD4+/CD8+were significantly higherin group Athan in group B (P < 0.05). There were no significant differences between the two groups in levels of TPSA, FPSA and lgM (P>0.05). Average postoperative follow-up was 15 months (range 3-36) in 36 patients. No recurrence or metastasis was found in all the patients by imaging studies,and no long-term complications were found. Conclusions Extraperitoneal LRP, as compared with tranperitoneal LRP, has clearer vision, fewer effects on abdominal organs, shorter surgical duration, less blood loss, faster postoperative recovery, and better protection of immune function. It is worth popularizing clin-ically.

Multilocus sequence typing (MLST) is a molecular genotyping method based on nucleotide sequencing. The procedure of this method characterizes isolates of bacterial species using the DNA sequencing of multiple housekeeping genes(usually seven). For each housekeeping gene, the different sequences present within a bacterial species are assigned as distinct alleles.For each isolate, the alleles at each of the loci define the allelic profile or sequence type (ST). MLST has the advantages of being robust (based on genetic data) and electronically portable to generate data that allow rapid and global comparisons between different laboratories. In this paper, the principle, method, data analysis, application, advantages and flaws of MLST are introduced.

Objective To analyze the antimicrobial susceptibility of Mycoplasma isolates for rational antimicrobial therapy. Methods BioM?rieux IST kit was used for identification and susceptibility testing of Mycoplasma strains.Results Mycoplasma was positive in 49.5% of the specimens tested.Of the Mycoplasma detected,Ureaplasma urealyticum(Uu)alone accounted for 74.7%,Mycoplasma huminis(Mh)alone accounted for 18.1%,and Uu+Mh was identified in 7.2% of the patients.The results of antimicrobial susceptibility testing showed that the Mycoplasma isolates were most susceptible to doxycycline (98.1%).Ciprofloxacin was the least active (17.3%).Conclusions Doxyeycline,josamycin,and clarithromycin can be used in the treatment of urinary tract infections caused by Mycoplasma.

Objective To understand the screening results and positive lesion situation of colonoscopy screening among high risk urban population of colon cancer in Chongqing Nan'an District to provide a basis for the community heath guidance.Methods The high risk subjects of colon cancer screened according to the item of the Early Diagnosis and Early Treatment of China Urban Cancer and in our center for completing colonoscopy screening during 2013-2016 were collected and analyzed on the positive rates of various lesions.Results A total of 435 subjects were included,141 positive cases were found with the total positive rate of 32.41% (141/435),in which 75 cases were male positive with the positive rate of 47.47% (75/158),and 66 cases were female positive with the positive rate of 23.83 % (66/277),the polyps detective rate was 28.27 % (123/435),tumor-like lesion detective rate was 7.59%(33/435),the adenocarcinoma detection rate was 0.46% (2/435);the total positive rate of male was higher than that of female(x2 =25.669,P<0.01).Conclusion The sequential screening mode in which the high risk population preliminarily screened out by community then performs colonoscopy examination has an important significance for discovering the intestinal tract lesion.

Objective To investigate the feasibility of the simultaneous measurement of right ventricular pressure-volume loops by cardiac catheterization and 2D electrocardiogram. Methods Patients referred for pulmonary hypertension underwent right heart catheterization in our hospital between June 1st, 2015 and June 1st, 2017 are to be enrolled in this study. The right ventricular volume was measured simultaneously by catheter and electrocardiogram. The pressure-volume loops were constructed by the parameters of the pressure and volume in the same cardiac cycle. Results The study completed in four cases and their pressure-volume loops were drawn. The obtained images were irregular and there was no relationship among them. As a result, the construction was a failure. Conclusions The construction of the right ventricular pressure-volume loops of pulmonary hypertension patients by simultaneous catheterization and 2D electrocardiogram is difficult to overcome the technology defects.

BACKGROUND: Vibrio vulnificus inside the body could activate the NF-κB signaling pathway and initiate the inflammatory cascade. The lung is one of the earliest organs affected by sepsis associated with acute lung injury. High mobility group protein B1 (HMGB1) is an important late-acting pro-inflammatory cytokine involving in the pathophysiology of sepsis. It is also involved in the injury process in the lung, liver and intestine. There has been no report on the involvement of HMGB1 in Vibrio vulnificus sepsis-induced lung injury. METHODS: Sixty rats were randomly divided into a normal control group (group A,n=10) and a Vibrio vulnificus sepsis group (group B,n=50). Sepsis was induced in the rats by subcutaneous injection of Vibrio vulnificus (concentration 6×108 cfu/mL, volume 0.1 mL/100g)) into the left lower limbs. The rats in group B were sacrificed separately 1, 6, 12, 24, and 48 hours after the infection. Their lungs were stored as specimens, lung water content was measured, and lung pathology was observed under a light microscope. The expressions of the HMGB1 gene and protein in the lungs were detected by RT-PCR and Western blot. Data were analyzed with one-way analysis of variance (ANOVA) and the LSD method for pair-wise comparison between the two groups.P<0.05 was considered statistically significant. RESULTS: Compared to group A (0.652±0.177), HMGB1 mRNA expression in the lungs of group B was significantly higher at 0 hour (1.161±0.358,P=0.013), 24 hours (1.679±0.235,P=0.000), and 48 hours (1.258±0.274,P=0.004) (P<0.05), and peaked at 24 hours. Compared to group A (0.594±0.190), HMGB1 protein expression at 6 hours (1.408±0.567,P=0.026) after infection was significantly increased (P<0. 05), and peaked at 24 hours (2.415±1.064,P=0.000) after infection. Compared to group A (0.699±0.054), lung water content was significantly increased at 6 hours (0.759±0.030,P=0.001),12 hours (0.767±0.023,P=0.000), 24 hours (0.771±0.043,P=0.000) and 48 hours (0.789±0.137,P=0.000) after infection (P<0.05). Compared to group A, pathological changes at 12 hours in group B indicate marked pulmonary vascular congestion, interstitial edema and inflammatory infiltration. Alveolar cavity collapse and boundaries of the alveolar septum could not be clearly identified. CONCLUSION:Vibrio vulnificus sepsis can lead to injury in rat lungs, and increased HMGB1 expression in lung tissue may be one of the mechanisms for injury from Vibrio vulnificus sepsis.
