Objective To inquire into the value of Liechtenstein Hernioplasty in the therapy of oblique or direct hernia.Method Liechtenstein was used in the therapy of 163 cases of oblique hernia (154 cases) and direct hernia (9 cases) from Feb.1998 to Jun.2001 and the clinical data was retrospectively studied.Most of them are of onset hernia except 8 cases of recurrent hernia.In 148 cases,the diameter of hernia ring is less than 2.5 cm and 30.1% of patients are elder than 65.The emergent operation was adopted in 12 cases.Results Off-bed exercises can be admitted at early stage of postoperation with slight pain and no local tension.Total recovery was obtained in 5-10 days after operation.After 6-36 months' follow-up,no mortality and less recurrence was detected.Conclusions There are so many advantages to treat oblique or direct hernia with Liechtenstein, such as minimized trauma, accelerated recovery,low recurrence rate and low cost. The indication of this operation involved all kinds of hernia (onset or recurrence of oblique or direct hernia,emergent operation of incarcerated oblique hernia, etc).

Objective To evaluate lactulose breath hydrogen test in diagnosis of small intestinal bacterial overgrowth in children.Me-thods Thirty-five children,aged 3 to 13 years old with mean (7.72?3.06) years old presented with chronic diarrhea,abdominal pain and flatulence.Among them,18 cases were male and 17 cases were female.Breath hydrogen test was carried out after the administration of a 0.5 g?kg-1 or 10 g lactulose,which was 100 g?L-1 solution.After the ingestion of lactulose,the breath hydrogen was collected in every 20 minutes and up to 3 hours.Small intestinal bacterial overgrowth was diagnosed as positive when the hydrogen concentration increased more than 20 mg?m-3 in a sample.Results Eighteen cases in 35 (51.43%) children were positive and 17 cases were negative.Among these positive cases,8 cases in 18 (22.86%) patients were typically double peaks in breath hydrogen concentrations.Among the causes of small intestinal bacterial overgrowth in children,4 cases with chronic superficial gastritis,4 cases with chronic bacterial enteritis,2 cases with malnutrition and anorexia,1 case with volvulus of stomach,1 case with massive resection of small intestine,1 case with steatorrhea and 5 cases with unknown causes.Four cases of chronic bacterial enteritis were gained remission by antimicrobial agents.The other cases were treated by lac-to-and bifidbacteria probiotics.Seven patients of the clinical systems were controlled,3 cases were improved remarkably and 4 cases were failed.Conclusions The lactulose breath hydrogen test is validated as screening test in the diagnosis of small intestinal bacterial overgrowth in children.Antimicrobial agents and bifidbacteria probiotics is effective in treatment of small intestinal bacterial overgrowth.

Objective The survey is based on status of sexual health and sexual needs for male patients with acute myocardial infarction and Percutaneous Transluminal Coronary Angioplasty (PTCA) plus stent implantation.The survey data provides the basis for guiding patients' health education.Methods General questionnaire,sexual knowledge status questionnaire and sexual health knowledge demand questionnaire were used to carried out the investigation in 214 cases of patients with PTCA plus stent implantation.Collected data entered into a database for statistical analysis.Results The overall score of sexual health of 214 patients was (8.79±2.52) points.There was a statistically significant difference in different education levels,occupation and monthly income.There was no statistically significant difference in different ages.The overall score of knowledge of sexual health demand was (29.40 ± 6.47) points.There was a statistically significant difference in different ages,education levels and occupations.There was no statistically significant difference in different monthly income.Conclusions The sexual knowledge cognitive level of patients with PTCA plus stent implantation is low,but they have higher demand of sexual health knowledge,the medical personnel should strengthen the knowledge of sex education for patients to improve the quality of sex.

Objective:To study the influence of vitamin C ( VC) on dendritic cells ( DC) ,and detect DC maturation,to provide a feasible method and thought for quickly preparating DC vaccines.Methods:Collected the peripheral blood (about 50 ml) from healthy volunteers,and isolated peripheral blood mononuclear cells with lymphocyte separation medium and obtain DC.With stimulating with different concentrations of VC for (24 h),then washed with PBS,and set up blank control group (V0).The expression of DC surface co-stimulating molecules CD80/86 and HLA-DR, CD40 was detected by flow cytometry.By setting the concentration gradient and time gradient, exciting optimal concentration and stimulating time of VC on DC, and analyzed the reasons of VC promoting DC maturation.Results:VC could effectively stimulate DC,CD80/86 expression had significantly increased contrast to the blank control group (V0).And the experiments show that VC’s best stimulating concentration was 1 mmol/L,and on the third day,the CD80/86 expression rate of VC group was (78.6±4.6) %,and blank control group V0 was (34.1±5.7) %.DC surface HLA-DR expression:VC (56.8± 4.4) %,blank control group V0 (25.4 ±4.7) %,the difference between two groups was statistically significant,P<0.05.CD40 and CD40L expression and results show that VC 2.5 mmol/L group of CD40 expression rate up to (59.3±3.7) %,while V0 group was only (11.1 ±2.4) %,that illustrate VC could significantly regulate CD40 expression on DC surface,but CD40L not reflect.Fluorescence mi-croscope results showed that DC’ s antigen catching ability was also significantly promoted.Conclusion:VC can significantly regulate DC maturity,and may up regulate CD40,thus promoting the express of CD80/86 and HLA-DR.When the concentration is 1 mmol/L,VC expresses the strongest regulation function on DC.

Objective To examine the sensitivity,specificity and accuracy of dobutamine stress quantitative tissue doppler imaging(DSE+TDI） for detecting CAD in the elderly patients.Methods Totally 98 patients underwent DSE+ TDI,and completed coronary angiography (CAG) in two weeks.Peak tissue velocity (Vpeak),peak tissue tracking (Dpeak),peak strain rating (SRpeak),peak strain (Speak)in different dobutamine stress stations were measured and analyzed during systolic period in mid-segments of left ventricle walls.Results In comparison of CAG,the sensitivity,specificity and accuracy of DSE+ TDI for detection CAD in the elderly patients showed that Vpeaks were 82.3％,61.7％,72.4％,Dpeak 82.4％,59.5％,77.4％,SRpeak 71.7％,82.2％,78％ and Speak 78.6％,72.3％,74.7％,respectively.All the adverse effects during tests were mild and transient.Conclusions Quantitative dobutamine stress tissue doppler imaging is a safe,effective and non-invasive technique and has higher sensitivity and specificity for detecting CAD in the elderly patients.

Objective To explore the correlation between extratemporal hypometabolism on preoperative 18F-FDG PET imaging and the outcome after temporal lobectomy in temporal lobe epilepsy (TLE)patients.Methods A total of 96 patients with intractable TLE who underwent temporal lobectomy were recruited.The outcome was evaluated according to International League Against Epilepsy (ILAE) 2001 outcome classification (OC) criteria:OC 1-3 was considered as good outcome and OC4-6 as poor outcome.The follow-up period was more than 2 years.The 18F-FDG PET brain images were retrospectively analyzed.The preoperative extratemporal cortical hypometabolism and extratemporal subcortical hypometabolism occurred in basal ganglia and thalamus were taken as independent exposure factors of poor outcome and the odds ratios (OR) were calculated respectively.Results Thirteen of 96 cases had poor outcome.Extratemporal cortical hypometabolism was found in 12 of 83(14.5％) cases with good outcome and in 11 of 13 cases with poor outcome.Extratemporal subcortical hypometabolism was found in 25 of 83 (30.1％) cases with good outcome and in 10 of 13 cases with poor outcome.The occurrence of extratemporal hypometabolism was significantly higher in poor outcome group than that in good surgical outcome group (cortical:x2 =26.63 ;subcortical:x2 =8.70; both P＜0.05).The OR of extratemporal cortical hypometabolism was 32.54,with 95％ CI of 6.40-165.44,and that of extratemporal subcortical hypometabolism was 7.73,with 95％ CI of 1.96-30.52.Conclusion Extratemporal cortical hypometabolism and subcortical hypometabolism in TLE patients are associated with poor outcome of temporal lobectomy in TLE patients.
