OBJECTIVE:To systematically review the efficacy of Live combined bacillus subtilis and enterococcus faecium in the prevention and treatment of Antibiotic associated diarrhea(AAD),and provide evidence-based reference for clinical treatment. METHODS:Retrieved from CBM,CJFD and Wanfang database,randomized controlled trials (RCT)of Live combined bacillus subtilis and enterococcus faecium(test group)versus placebo(control group)in the prevention and treatment of AAD. After data ex-tract and quality evaluation,systematical evaluation was performed by using Rev Man 5.0 statistics software. RESULTS:A total of 21 RCT were included,involving 3 881 patients. According to the purpose of different purpose of druguse,the RCT were divided into prevention group and treatment group. Results of Meta-analysis showed the incidence of diarrhea in prevention test group was significantly lower than control group[OR=0.27 ,95% CI(0.22 ,0.32),P<0.001] ,the average hospitalization time in prevention test group was significantly less than control group [MD=-53.19,95%CI(-79.63,-26.75),P<0.001],and the total clinical ef-fective rate in treatment test group was significantly higher than control group[OR=6.76,95%CI(4.16,10.98),P<0.001]. CON-CLUSIONS:The efficacy of Live combined bacillus subtilis and enterococcus faecium are good in the prevention and treatment of AAD. However,due to the limit of methodological quality and sample size,it remains to be further verified with more rigorously designed and long-term follow-up of large-scale RCT.

Objective The purpose of this study was to examine the relationship between acute mountain sickness ( AMS) and AMS susceptibility indices before ascent to high altitude and to evaluate their predictive value for AMS. Methods A total of 314 healthy male a-dults were voluntarily enrolled. Their 22 physiological and mental indices of AMS susceptibility were obtained before exposure high altitude. The diagnoses of AMS were based on the Lake Louise score ( LLS) ,an international standard scoring system for AMS. According to the char-acteristics of selected AMS susceptibility indices and the strong fault tolerance of neural network theory, the learning vector quantization ( LVQ) neural network method was adopted to build the prediction model of susceptibility to AMS. Results The results showed the sensitiv-ity of the LVQ model which distinguishes subjects with no-AMS reached 95. 00%,the average correct-prediction precision ultimately reached 72. 22%. The result of prediction is believable. Conclusion The builded LVQ model provide a scientific method for screening crowd who quickly ascend to high altitude,and also can lead to an effective preliminary screening of susceptibility to AMS.

Objective To investigate the exposure level of VOCs in different population and the health effects. Methods In 2005, a questionnaire survey relating to inhalation exposure assessment of VOCs and housing decoration characteristics was carried out in 200 newly decorated apartments (628 residents), 30 house decoration workers and 20 painting workers of an automobile manufacture factory. Indoor concentrations of formaldehyde, BTEX-compounds and TVOC were measured in typical apartments, offices, houses in where the decoration workers were operating, the painting workshops, and public indoor environments. Average daily exposure doses and potential doses for common people at home (non-occupational exposure group) and workers in occupational environments (occupational exposure group) to formaldehyde and BTEX-compounds and TVOC were estimated by combining the survey results with monitoring data. Results The percentages of whom having different discomfortable symptoms in the workers in the painting workshop were higher than that in common people (P

Objective To evaluate the application of the polymethyl methacrylate (PMMA) artificial eye in acquired ophthalmostewesis. Methods We summarized the experience in the application of PMMA in prosthesis for 8 years. 1155 patients were involved in the artificial eye custom-made program. The artificial eye was individually prepared based on the patient's condition and characters of the healthy eye.Results PMMA artificial eye associated with hydroxyl apatite implantation gave good cosmetic results with good motility, and there was no rejective reaction. The artificial eye was almost same to the real one in color and transparency. Conclusion It is suggested that PMMA is one of the best materials for manufacture of artificial eye at present.

Objective To evaluate the clinical effect of the procedure that involves drilling and inserting a motility peg at the time of hydroxyapatite orbital implant.Methods 89 patients who needed hydroxyapatite orbital implant were divided into groups A and B.The patients in group A were drilled and inserted a motility titanium peg when hydroxyapatite implantation.The patients in group B were drilled and inserted a motility titanium peg 6 months after hydroxyapatite implantation.Data were recorded.including the rate of postoperative pain and conjunctive edema,postoperative facial appearance,motility of the artifieial eye,the rate of hydroxyapatite exposure,excursion and extrusion of titanium peg and other complications.Results The mobility of the prosthesis was 44.97%in group A,and 45.34%in group B.There was no difference in appearance and the motility of their artificial eye between the two groups.The rate of excursion of titanium peg was 4.2% in group A and 7.3%in group B and no statistical difference was found between the two groups.There were no prosthesis exposure,extrusion of titanium peg,secondary infeetion and other complication in one-year follow-up.There were no difference in the rate of postoperative pain and eonjunctive edema in first operative stage.The postoperative reaction in group A was lighter than that in group B in secondary operanve stage.Conclusion The hydroxyapatite orbital implant primary procedure drilling is simple,safe,convenient and effective.It is worth to recommend that procedure that involves drilling and inserting a motility peg at the time of hydroxyapatite orbitaI primary implant.

Objective To investigate the effect of hypertension on the large artery elasticity index (C1),the small artery elasticity index (C2) and the medial structure of the ascending aorta as well as the relationship between artery elasticity and the medial structure of the ascending aorta.Methods Sixty patients with CHD receiving coronary artery bypass graft surgery at our hospital were divided into two groups:30 patients in the hypertension group and 30 patients in the non-hypertension group.C1 and C2 were measured using the CVProfilor DO-2020 system.Sections of tissues taken from the anterior wall of the ascending aorta during the surgery were subjected to Masson's trichrome staining for the detection of vascular smooth muscle and collagen fibers and Weigert's resorcin-fuchsin staining for the detection of elastic fibers.The relative areas of vascular smooth muscle fibers,collagen fibers and elastic fibers of the ascending aorta were measured by a computer image analysis system under the light microscope.The linear correlations of C1 and C2 with the medial structure of the ascending aorta were analyzed.Results C1 in the non hypertension group was higher than that in thehypertensiongroup[11.9±1.8 (ml/mmHg×10) w 13.1±2.5 (ml/mmHg×10),t 2.22,P ＜0.05].In the media of the ascending aorta,the relative content of collagen fibers was higher,while the relative content of elastic fibers was lower in the hypertension group than in the non-hypertension group [(46.0±3.8)％ w (42.2±3.0)％,(17.5±3.5)％ vs.(19.3 2.7)％,respectively,t=4.24 and 2.20,P＜0.01 or 0.05].C1 was positively correlated with the relative content of elastic fibers but negatively correlated with the relative content of collagen fibers in both groups (r=0.52 and 0.39,respectively,P＜0.05 or 0.01).Conclusions The main pathogenic basis of hypertension-induced decline in arterial elasticity in CHD patients is increased collagen fibers and reduced elastic fibers with disorganization of the two types of components.C1 may accurately reflect the effect of hypertension on medial collagen fibers and elastic fibers in the ascending aorta.

Objective To evaluate the clinical value of serum MUC1(sMUC1)in the patients with multiple myeloma.Methods The enzyme linked immunosorbent assay(ELISA)was used to compare the sMUC1 levels in the 12 cases of newly diagnosed multiple myeloma.15 cases of post-chemotherapy and 46 healthy donors.Results The mean concentration of sMUC1 in the newly diagnosed patients with multiple myeloma was 33.44 U/ml(10.86～88.80 U/ml).In the patients of post-chemotherapy the mean concentration was 11.6U/ml(3.92～22.22 U/ml),and in the healthy donors the concentration was 12.81 U/ml(3.84～30.45 U/ml).The level of sMUC1 in the new diagnosed patients was significandy higher than that in the patients of post-chemotherapy(P=0.001)and healthy donors(P=0.000).There was no significant difference between post-chemotherapy and healthy donors(P=0.461).Conclusion sMUC1 may be one of the tumor markers for the diagnosis of multiple myeloma.sMUC1 could also be used as one of the indicators of prognosis and the evaluation of the chemotherapy efficacy.sMUC1 might be a potential target for the immunotherapy to the patients with multiple myeloma.

Objective To investigate early and midterm outcomes after minimally invasive1-stop or 2-stage MICSCABG and PCI hybrid surgery.Methods Between June 2011 and February 2015, 28 patients(19 males and 9 females) with multiple coronary artery disease underwent MICS-CABG and PCI hybrid surgery, 4 cases of which were1-stop hybrid surgery and 24 cases were 2-stage.All patients were followed up to major adverse events(recurrent angina, secondary myocardial infarction, congestive heart failure, serious arrhythmias, secondary bypass graft) as the end point event.Results All patients were no perioperative deaths, shock, infection and myocardial infarction.ICU stay time was(22.9 ± 12.5) h, hospital stay time was(6.75 ±2.10) days, intubation time was(21.1 ± 17.7) h.Perioperative1-stop and2-stages hybrid surgery had significant statistical differences in ICU stay time and intubation time[(41.8 ±32.9) h vs.(16.5 ± 8.5) h;(40.0 ± 34.2) h vs.(18.8 ± 8.5) h;P ＜ 0.05].Patients were followed up for 1-44 months, averaged (17.9 ± 12.8) months.The postoperative major adverse event rate was 7.14％, one patient died of cerebral hemorrhage after 6 months, and one patient underwent coronary angiography because angina.Conclusion l-stop or 2-stage MICS-CABG and PCI hybrid surgery provides a safe,effective and cosmetic revascularized method to patients with multiple coronary artery disease.Meanwhile,the procedure does not destroy the way of re-operation.The perioperative and early results of follow-up are satisfactory.
