OBJECTIVETo compare the difference in the clinical efficacy on mild and moderate female stress urinary incontinence (FSUI) between transcutaneous acupoint electrical stimulation and oral administration of midodrine hydrochloride tablets.

METHODSNinety cases of mild and moderate FSUI were randomized into an observation group and a control group, 45 cases in each one. In the observation group, the transcutaneous acupoint electrical stimulation was applied to Ciliao (BL 32), Shenshu (BL 23), Zigong (EX-CA 1), Guanyuan (CV 4) and Qihai (CV 6), once a day. In the control group, midodrine hydrochloride tablets were prescribed for oral administration, 2. 5 mg per treatment, three times each day. The duration of treatment was 4 weeks. The score of international consultation on incontinence questionnaire-urinary incontinence short form (ICI-Q-SF) and leakage of urine in 1 h urinal pad test were observed before and after treatment in the patients of the two groups, and the efficacy was compared between the two groups.

RESULTSThe score of ICI-Q-SF and leakage of urine in urinal pad test after treatment were all improved apparently as compared with those before treatment in the two groups (all P<0. 01), and the results in the observation group were better than those in the control group (both P<0. 01). The total effective rate was 86. 7% (39/45) in the observation group, which was better than 68. 9% (31/45, P<0. 05) in the control group.

CONCLUSIONThe transcutaneous acupoint electrical stimulation achieves the better efficacy on FSUI as compared with the oral administration of midodrine hydrochloride tablets. This therapy effectively improves the patient's urine control ability and reduces leakage of urine.

Objective To summarize the clinical features,treatment and prognosis of bullous systemic lupus erythematosus (BSLE).Methods Clinical data were collected from 6 cases of BSLE between May 2009 and September 2015,and were analyzed retrospectively.Results Among the 6 patients,2 were male and 4 were female.The mean age of onset was 34 years.All the 6 patients presented with tense blisters and bullae arising on an erythematous base or normal skin,which were arranged in an annular pattern in 3 patients.The SLE Disease Activity Index (SLEDAI) score was ＞ 4 in all the 6 patients.Histopathological examination showed subepidermal blisters or fissures in all the patients.Direct immunofluorescence (DIF) revealed continuous linear deposition of immunoglobulin G (IgG),IgM and IgA in all the patients,linear deposition of C3 in 4 patients,and linear deposition of Clq in 2 patients at the basement membrane zone (BMZ).All the 6 patients were treated with oral glucocorticoids and hydroxychloroquine,and 2 patients were additionally treated with cyclophosphamide.During the follow-up period,adverse reactions to different extents were observed in the 6 patients.Conclusions BSLE mainly occurs in young and middle-aged people.Histopathologically,subepidermal blisters or fissures can be observed with linear deposition of IgG,IgM,IgA,or C3 along the basement membrane zone on DIF.

Objective To investigate the association between HLA-DRB1 alleles and pemphigus vulgaris (PV) in a Han population in Sichuan.Methods Polymerase chain reaction with sequencespecific primer (PCR-SSP) method was used for low-resolution and high-resolution typing of HLA-DRB1 alleles in 19 patients of Han nationality with PV and 25 healthy controls in Sichuan.Allele frequencies were calculated,and differences in the allele frequency between the above two groups were compared by using chisquare test.Results Totally,9 kinds of DRB 1 low-resolution alleles and 19 kinds of DRB 1 high-resolution alleles were identified in the PV patients and healthy controls.Frequencies of the DRB1* 14 allele (39.47％[15/38] vs.8.00％[4/50],x2 =17.43,P ＜ 0.05) and DRB1*1405 allele (15.79％[6/38] vs.2.00％[1/50],x2 =4.25,P ＜ 0.05) were significantly higher in the PV patients than in the healthy controls.Conclusion The HLA-DRB1*14 allele may be a common susceptibility gene for PV in the Han population in Sichuan,and the HLA-DRB1* 1405 allele may be most closely associated with PV.

Objective Through comparision of HER2/neu status detected by immunohistoehemistry (IHC),fluorescence insitu hybridization(FISH)and chromogenic insitu hybridization(CISH),to explore the clinical significance of FISH and CISH on detecting gene status of HER2.Methods Sixty-four paraffinembedded breast samples whose pathological types were infiltrating ductal carcinomas were tested by IHC for HER2 protein overexpression and CISH,FISH for HER2 gene status.The rate of chromosome 17 polysomy was also analyzed.Results Among the cases of HER2 protein overexpression(+++)group,the concordant ratios of IHC and CISH.FISH detecting HER2/neu status were 100%.Among the cases of HER2 protein overexpression(++)group,the concordant ratios were 95.83%and 91.67%.Among the cases of HER2 protein overexpression(+/-)group,the concordant ratios were also 100%.One case in which FISH and CISH were performed yielded the different results.so the general coincident rate was 98.41%.The incidence of chromosome 17 polysomy Was 45.16%,45.83%and 11.11%in three IHC(+++,++,+/-)groups,and the total incidence was 40.62%.ConclusionIHC is a preliminary screening method;HER2 gene status detected by CISH and FISH have high concordant ratio,CISH is a more convenience and viable method to detect HER2/neu status,when doubling interference of fichromosome 17 polysomy,we need to select FISH further.

Objective To explore the relationship between mathematical characteristics of cardiotocograph in electronic fetal monitoring (EFM) and umbilical blood acidosis,and help to evaluate the clinical significance of indeterminate EFM.Methods A total of 85 vaginal delivery cases (or transfer to caesarean section during labor) hospitalized in Peking University Third Hospital during February 4 to December 5,2011 was enrolled in this retrospective study.EFM monitored 0.5-1 hour before delivery was recorded and the mathematical characteristics as the baseline,deceleration area per unit time (cm2/min),deceleration duration ratio and some other variables of EFM were analyzed.All cases were divided into acidosis (n=12) and non-acidosis group (n=73) based on the umbilical blood gas results.Rank sum test or t-test were used to compare the difference on mathematical characteristics between these two groups.Results The deceleration duration ratio and deceleration area per unit time in acidosis group were 0.56±0.17 and 0.45 cm2/min (0.38-0.79 cm2/min),which were higher than those in non acidosis group [0.42±0.14 and 0.30 cm2/min (0.19-0.40 cm2/min)],the differences were statistically significant (t=2.889,Z=2.587,both P＜0.05).There were no statistically significant differences in the number of mild variable deceleration and severe deceleration per unit time between acidosis group and non acidosis group [(0.44± 0.14)/min vs (0.41±0.13)/min,t=1.318,P＞0.05; 0.033/min (0.016-0.062/min) vs 0.016/min (0.008-0.033/min),Z=-1.596,P＞0.05].Conclusions The deceleration duration ratio and deceleration area per unit time can be used to assist the interpretation of indeterminate EFM.

Objective:To investigate the influence of clinical outcomes and the risk factors of poor prognosis for preoperative nutritional risk in gastric cancer patients.Methods:A prospective study was performed in 140 patients with gastric cancer and the nutritional risk screening 2002 (NRS 2002) was done.The influence of preoperative nutritional risk on postoperative complications,hospital stay,ICU stay,hospital expenses,60 days readmission and mortality was analyzed,and the risk factors of perioperative complication were identified by univariate and multivariate analysis.Results:The significant difference (NRS 2002 ≥ 3 group vs.NRS 2002 ＜ 3 group) was observed in the rates of overall postoperative complications,pulmonary infection,overall hospital stay and postoperative hospital stay (P ＜ 0.05).The rates of anastomotic fistula,pleural effusion,60 days readmission,60 days mortality and hospitalization expenses in NRS 2002 ≥ 3 group were higher than that of NRS 2002 ＜ 3 group,but there were no differences between the two groups (P ＞ 0.05).By univariate and multivariate analysis,preoperative high cholesterol levels and preoperative nutritional risk are the risk factors of poor prognosis and postoperative complications.Conclusion:Preoperative high cholesterol levels and preoperative nutritional risk are independent risk factors of postoperative complications.

Objective To study intraoperative neural electrophysiological monitoring applied in lumbosacral spinal cord tumor resection.Methods We retrospectively reviewed the clinical data of 212 patients undergoing lumbosacral spinal cord tumor resection with or without intraoperative neural electrophysiological monitoring in our hospital.The patients were divided into two groups:124 patients in the monitored group received intraoperative neural electrophysiological monitoring while 88 ones in the control group did not.The monitoring was performed by recording the cortical somatosensory evoked potential (CSEP),dermatomal somatosensory evoked potential (DSEP) and electromyography (EMG).The patients were followed up for 3-6 months and their postoperative outcome was analyzed.Results There were significant differences in the outcome (P <0.05),but no difference was found in the incidence of complications between the monitored group and the control group.The sensitivity of CSEP +DSEP+EMG was 100%,and the specificity was 55.9% in the former group.Conclusion Combined monitoring with CSEP,DSEP and EMG during lumbosacral spinal cord tumor resection is valuable in protecting the spinal nerve roots and ensuring better operation safety.
