Objective To study the feasibility of re-operation of gynecological laparoscopy.Methods Clinical records of 47 patients with gynecological diseases undergoing a re-laparoscopy from December 1995 December 2003 were analyzed retrospectively.Results The re-operations of laparoscopy were successfully accomplished in 46 patients(97.9%) while a conversion to open surgery was required in 1 patient.The re-operation time was 30~80 min(mean,50 min),and the in-hospital stay was 2.5~5 days(mean,3.5 days).No long-term complications were noted in 44 patients on a postoperative follow-up for(1~4) years.Out of 19 patients with infertility, 1 patient had a natural pregnancy and 6 patients were pregnant with the help of artificial reproductive techniques.Supportive medical treatment had been given in patients with endometriosis postoperatively,3 of whom experienced symptomatic improvements and 1 of whom had a natural pregnancy.Conclusions For patients with a history of laparoscopy,a re-operation of gynecological laparoscopy is safe and feasible.

Objective To investigate transmission routes of healthcare-associated infection(HAI)caused by methi-cillin-resistant Staphylococcus aureus (MRSA),and make effective measures for preventing and controlling the oc-currence and epidemic of HAI caused by multidrug-resistance bacteria.Methods From February 24 to March 29, 2012,12 MRSA-infected patients were performed epidemiological study,these patients underwent bronchoscopy be-cause of tracheal stenosis,strains were identified by amplifying the sequences of 16S rRNA ,femA and mecA with real-time quantitative polymerase chain reaction (PCR),homology analysis of strains were performed by Spa geno-typing.Results All 12 MRSA-infected patients were susceptible to multidrug-resistance bacterial infection,5 cases of MRSA infection occurred during this hospitalization.Detection of specimens from health care workers and envi-ronment were all negative;Spa gene of all 12 MRSA isolates was type t 030 ,which was the main epidemic strain in Asia;Spa gene of Staphylococcus aureus isolated from nurses’noses was type t1425 .Conclusion The assumption of MRSA spread among health care workers aren’t supported by the epidemiological investigation results,genotypes of 12 MRSA isolates are identical,but the result of gene typing can’t be as the evidence of homology of infection ;patients at high risk for MRSA infection should be screened as early as possible,early contact isolation should be performed,so as to prevent and control the occurrence of HAI.

Objective Determination of Wilson disease gene mRNA expression in human fibroblast cell strain (Me32aT22/2L) by reverse transcription-polymerase chain reaction (RT-PCR). Methods Using lipofection reagent, the plasmid vector carrying the Wilson disease gene (pRc/CMV-WD) was transferred into Me32aT22/2L cultured in serum free complement medium. RT-PCR was used to determine WD mRNA expression in Me32aT22/2L. Results Wilson disease gene expression was detected in Me32aT22/2L, while no specific signals were detected in untransfected fibroblast. Conclusions It demonstrated that Me32aT22/2L strain could express the Wilson disease gene, suggesting that Wilson disease gene transfer might develop a new approach to study Wilson disease.

Objective To investigate the iodine nutrition level of vulnerable people in Inner Mongolia after adjustment of iodized salt standard and to provide theoretical bases for scientific iodine supplementation. Methods In 2013, 3 cities were selected from eastern, central and western parts of Inner Mongolia in accordance with the random number table, 3 or 4 counties were selected from each target city, 5 units according to their sub-area position of east, south, west, north and center were selected from each county, and then 1 township was selected from each unit, 5 groups of target population including school children aged 8- 10, women of childbearing age, pregnant and lactating women and infants each at least 10 people were investigated in each township. Edible salt samples from their homes and urine samples were collected. The direct titration method among the generic methods of iodide testing for salt production industry (GB/T 13025.7-2012) was used to determine the salt iodine level, and As3+-Ce4+catalytic spectrophotometry using ammonium per sulfate digestion (WS/T 107-2009) was used to test the urinary iodine level. Results Totally 3 300 samples of edible salt from local residents had been examined and median iodine was 26.20 mg/kg. The median of urinary iodine was 190.6μg/L of 1 289 school-age children;was 183.6μg/L of 621 women of childbearing age; was 178.2 μg/L o f 876 pregnant women; was 178.6 μg/L of 664 lactating women and was 167.7μg/L of 599 infants. Conclusion After adjustment of iodized salt standard, iodine nutrition level is suitable in all vulnerable people.

Objective To evaluate the efficacy and safety of midodrine hydrochloride in the treatment of intradialysis hypotension (IDH)in maintenance hemodialysis (MHD)patients.Methods One hundred and tburteen MHD patients from 8 dialysis centers with IDH were enrolled in the study.These patients took orMly midodfine for 4~6 weeks.Midodrine(2.5~10 mg)was given 15~30 minutes after the beginning of hemodialysis,and another 2.5~10 mg was used during hemodialysis if systolic blood pressure(SBP)increased less than 20 mm Hg.The total usage of each dialysis session was not more than 20 mg.The pre-,intra-,post-hemodialysis blood pressure and heart rate,the pre-and post-hemodialysis body weight,the uhrafiitrated volume of each dialysis,the pre-and post-treatment liver and renal function and electrocardiogram were measured and recorded.The symptoms of IDH were observed. Results Compared to those before treatment with midodrine hydrochloride,the minimum intradialysis SBP and heart rate at that time,the post-dialysis SBP and heart rate,and total uhrafiitrated volume changed significanlly (P<0.01).The total effective rate was 84.2%.And the symptoms of IDH were improved significantly (P<0.01).The side effects were observed in only 2 patients.Conclusion Midodrine iS safe and effective for the treatment of IDH.

Objective:To investigate the protective effect and mechanism of Acronychia pedunculata water extracts on UV-induced light damage of human keratinocytes.Methods:The experiment was conducted from December 2018 to April 2020 in the Guangxi Medical University Laboratory of Genetics. The photoaged keratinocyte model was used, the cells were co-cultured with different concentrations of Acronychia pedunculata water extracts. The cell proliferation rate was detected by CCK-8 method. The levels of reactive oxygen species (ROS), malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPX) and total antioxidant capacity (T-AOC) of cells were detected by a test kit. The levels of IL-1β, IL-6 and tumor necrosis factor-alpha (TNF-α) were determined by ELISA.Results:The proliferation of HaCaT cells was promoted by 0.5 mg/L-2.0 mg/L of the extracts. Compared with control group, the proliferation rate of HaCaT cells in the experimental group was significantly increased ( P<0.05). Compared with control group, the contents of ROS was decreased ( F=214.67, P<0.05), MDA was decreased ( F=811.88, P<0.05), SOD was increased ( F=28.95, P<0.05), CAT was increased ( F=213.31, P<0.05), GPX was increased ( F=65.10, P<0.05), T-AOC was increased ( F=305.58, P<0.05), IL-1β was decreased ( F=15.46, P<0.05), IL-6 was decreased ( F=59.2, P<0.05), and TNF-α was decreased ( F=33.13, P<0.05). Conclusions:The extracts of 0.5-2.0 mg/L of Acronychia pedunculata have protective effects on the photoaging cell model, which may be related to the increase of SOD, CAT, GPX and other antioxidant enzymes and the level of T-AOC in photoaging HaCaT cells, and the decrease of ROS, MDA content and the expression of inflammatory cytokines.
