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 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 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 In the computer-oriented network management platform,discharged patients with type 2 diabetes was intervened with multi-form follow-up forms,and analyze the different effects at different stages of health education interventions.Methods Based on diabetes management center database follow-up system,various forms of follow-up program was used for 125 patients with type 2 diabetes who discharged from June 2014 to January 2015,they were followed for a period of six months,the self-management behaviors and blood glucose of patients at different stages,15 day,1 month,3 months,6 months were analyzed and compared.Results After discharged 15 days,1 month,3 months,6 months,the compliance to diet,exercise,blood glucose monitoring and medication of type 2 diabetes was statistically significant (x2=8.274-28.634,P＜ 0.05).The number of discharged patients regularly attending health education seminars,screening complications and glycosylated hemoglobin,attending outpatient follow-up program is gradually increased,the difference was statistically significant (x2=37.722-75.000,P ＜ 0.05).2-hour postprandial blood glucose level and compliance rate,fasting blood glucose level control and compliance rate were stable,the difference were no statistically significant (P ＞ 0.05).Conclusions The computerized various forms of follow-up programs can improve the self-management behaviors and maintain a stable glycemic control of discharged patients with type 2 diabetes.

Objective To investigate the value of differential diagnosis for subcortical ischemic vascular dementia(SIVD)and Alzheimer's disease(AD)with memory and executive screening(MES) scale. Methods Fifty SIVD and 50 AD patients treated in the outpatient and wards of the Department of Neurology,Fuxing Hospital,Capital Medical University from June 2012 to November 2013 were enrolled retrospectively. They were enrolled in either a SIVD group or an AD group. Fifty healthy subjects in Yuetan community of Fuxing hospital were selected as a control group at the same period. The age,sex and education level of the subjects in the 3 groups were matched. The Mini-Mental State Examination( MMSE) and MES were used to measure all subjects and were compared;receiver operating characteristic curves was used to analyze the radio of memory and executive part for SIVD and AD discrimination. Results (1)There was no significant difference in total MMSE score between the SIVD group and the AD group(20. 6 ± 5. 5 vs. 20. 6 ± 3. 3;P>0. 05).(2)There were significant differences in each MES indexes among the patients of the 3 groups(all P>0. 05). The 1,3,4 and 5 scores for the sentence memory in the SIVD group were significantly higher than those of the AD group. There were significant differences(all P<0. 01). The indicators of executive part:the continuous action,instruction and action contradictory stimulation,knock and un-knock with finger scores of the SIVD group were all lower than those of the AD group(5. 1 ± 3. 1 vs. 7. 3 ± 2. 1, 5. 2 ± 3. 0 vs. 7. 7 ± 1. 9,3. 5 ± 4. 4 vs. 6. 2 ± 4. 3;all P<0. 01). The MES-R of the SIVD group was higher than that of the AD group(1. 2 ± 0. 7 vs. 0. 5 ± 0. 2;P>0. 05).(3)When MES-R was≥0. 7,the sensitivity and specificity of differentiating SIVD were 76. 7% and 83. 3%,and the total score of MMSE for differentiating the sensitivity and specificity of SIVD were 40. 0% and 0. 7%. Conclusion The differences of MES reflecting sentence memory and executive part may better distinguish the patients with SIVD and AD.

Objective To research and evaluate measuring Toric intraocular lens (Toric IOL) alignment by iTrace aberration without mydriasis.Methods Forty-five eyes of 35 patients underwent phacoemulsification in Tianjin Medical University Eye Hospital from June 2015 to February 2016 were enrolled.Follow-up and iTrace aberration examination were performed at postoperative 1 week.The internal optics aberration astigmatism axis was transformed into postoperative Toric IOL alignment.The result and the Toric IOL alignment measured by tradition slitlamp method were compared by linear correlation and difference.Results At postoperative 1 week,the uncorrected distant visual acuity and corrected distant visual acuity were (0.19 ± 0.12)LogMAR and (0.10 ±0.09) LogMAR.The UCVA was 20/40 or better in 42 eyes (93.3％).The mean IOL misalignment measured by slitlamp was (3.13 ± 2.86) degrees (ranged 0-9 degrees) and by the iTrace aberration was (4.44 ± 3.42) degrees(ranged 0-13 degrees),there was statistical significant difference (t =-2.321,P =0.025).The mean difference in the error of the Toric intraocular lens alignment measured by iTrace aberration and the slitlamp was (3.67 ± 3.59) degrees (ranged 0-14 degrees).The results showed that there was less than 5 degrees of difference between the two methods in 32 eyes (71.1％),locate 5 to 10 degrees in 9 eyes (20％),more than 10 degrees in 4 eyes (8.9％).The correlation between the 2 methods showed significant linear relationship (r =0.926,P ＜ 0.01).Conclusion Using iTrace aberration can accurately measure Toric intraocular lens alignment without mydriasis,the result has some reference value.
