A strain no.H5 isolated from Rhizophora stylosa Griff in Zhanjiang had a good antagonistic activity against Aspergillus niger,pathogen of Dracaena Sanderiana black-rot disease.It was identified as Bacillus licheniformis.Dual culture,mycelium growth rate and inhibitory zones were used to test the effect. Strong inhibition was shown against A.niger.Inhibitory ratios of H5 germ-free fermented filtrate on mycelium growth and conidial germination were 91.9%and 100%respectively.In addition,mycelia on the edge of antagonistic band became abnormal and over-branching.Meanwhile,a lot of vesicles appeared on the surface.When treated with heat,acid and alkali,the filtration of H5 was always with stable activity.Precipitate in 55%saturated ammonium sulfate dissolved in phosphate buffer solution maintained most of the activity after high pressure steam sterilization for 25 minutes.It was preliminarily considered as a kind of heat resistant protein.

The aim of this paper is to apply near infrared spectroscopy techniques to construct a rapid identification method for 8 kinds of mineral Chinese Medicines containing carbonates. The qualitative model using clustering analysis method in OPUS software can identify accurately 8 kinds of carbonate-containing mineral Chinese medicines. The near-infrared quantitative model was established by using partial least squares method (PLS) for 7 mineral Chinese Medicines in which main component is calcium carbonate. Compared with the results by EDTA titration, the established quantitative analysis model for calcium carbonate content showed a good prediction result that when the content is between 47.61% -99.17%, the average relative deviation of the prediction result is 0.24% and the average recovery rate was 100.3%. The results also showed that the model using near infrared spectroscopy can get not only a rapid identification of the 8 mineral Chinese medicines containing carbonates, but also an accurate and reliabe content determination of calcium carbonate for the 7 mineral Chinese medicines which contain the component.

ObjectiveTo explore the feasibility and outcomes of natural orifice transanal laparoscopic Soave procedure for Hirschsprung's disease and allied disorders (HAD).MethodsFrom March 2010 to December 2011,31 cases (at the age from 3 mos to 6 yrs) with Hirschsprung's disease or allied disorders (5 cases)underwent laparoscopic-assisted Soave pull-through procedure at two tertiary hospitals.We modified this technique by mobilizing the left hemicolon or whole colon via rectal muscular sleeve approach under transanal or transumbilical laparoscopic vision,then endorectal pull-through to completearectosigmoidectomyorsubtotalcolectomy. ResultsAllprocedureswerecompleted successfully.A rectosigmoidectomy was performed in 16 cases with classic HD and subtotal colectomy in 15 cases with extended HD and HAD.The average operative time was ( 117 ± 13) min.The length of the resected segment was 35 -80 cm,and the estimated blood loss was 5 -20 ml. One infant developed postoperative intestinal obstruction that required open exploration.Follow-up of one to 20 mos found no stoma stenosis or constipation recurrence. Enterocolitis developed in 1patient.ConclusionsTransanal or transumbilical laparoscopic-assisted Soave pull-through surgery is safe,effective and with a benefit of much less invasion and almost invisible scars.

OBJECTIVETo investigate the changes of vascularized fibular bone height after transplantation for mandibular reconstruction.

METHODSThirty-two patients with mandibular defects were reconstructed with vascularized fibular bone. Postoperative follow-up pantomography was used to evaluate the changes of bone height.

RESULTSAt different distance from the vessel pedicles, the changes of bone height showed no significant difference. The height of fibular bone decreased gradually with time and reduced by 6.64% at 1 year postoperatively.

CONCLUSIONSMultiple segmental osteotomies had no effect on blood flow and the different pieces of graft after modeling by osteotomy experienced the similar reconstruction. The volume of grafted fibular bone almost remained stable.

Background/Aims: Ineffective esophageal motility (IEM) is common in patients with gastroesophageal reflux disease (GERD) and can be associated with poor esophageal contraction reserve on multiple rapid swallows. Alterations in the esophageal microbiome have been reported in GERD, but the relationship to presence or absence of contraction reserve in IEM patients has not been evaluated. We aim to investigate whether contraction reserve influences esophageal microbiome alterations in patients with GERD and IEM. Methods: We prospectively enrolled GERD patients with normal endoscopy and evaluated esophageal motility and contraction reserve with multiple rapid swallows during high-resolution manometry. The esophageal mucosa was biopsied for DNA extraction and 16S ribosomal RNA gene V3-V4 (Illumina)/full-length (Pacbio) amplicon sequencing analysis. Results: Among the 56 recruited patients, 20 had normal motility (NM), 19 had IEM with contraction reserve (IEM-R), and 17 had IEM without contraction reserve (IEM-NR). Esophageal microbiome analysis showed a significant decrease in microbial richness in patients with IEM-NR when compared to NM. The beta diversity revealed different microbiome profiles between patients with NM or IEM-R and IEM-NR (P = 0.037). Several esophageal bacterial taxa were characteristic in patients with IEM-NR, including reduced Prevotella spp.and Veillonella dispar, and enriched Fusobacterium nucleatum. In a microbiome-based random forest model for predicting IEM-NR, an area under the receiver operating characteristic curve of 0.81 was yielded. Conclusions In symptomatic GERD patients with normal endoscopic findings, the esophageal microbiome differs based on contraction reserve among IEM. Absent contraction reserve appears to alter the physiology and microbiota of the esophagus.

BACKGROUND AND PURPOSE: The requirement for neurology liaison is increasing in accordance with the growing health care demands associated with aging populations. The aim of this study was to characterize the nature of neurological inpatient liaisons (NILs) to help plan for the appropriate use of neurology resources. METHODS: This was a retrospective cross-sectional study of NILs in a secondary referral hospital over a 12-month period. RESULTS: There were 853 neurological consultations with a liaison rate of 3% per admission case. Chest medicine, gastroenterology, and infectious disease were the three most frequent specialties requesting liaison, and altered consciousness, seizure, and stroke were the three most frequent disorders for which a NIL was requested. Infection was the most common cause of altered consciousness. Epilepsy, infection, and previous stroke were common causes of seizure disorders. Acute stroke accounted for 44% of all stroke disorders. Electroencephalography was the most recommended study, and was also the most frequently performed. Ninety-five percent of emergency consultations were completed within 2 hours, and 85% of regular consultations were completed within 24 hours. The consult-to-visit times for emergency and regular consultations were 44+/-47 minutes (mean+/-standard deviation) and 730+/-768 minutes, respectively, and were shorter for regular consultations at intensive care units (p=0.0151) and for seizure and stroke disorders (p=0.0032). CONCLUSIONS: Altered consciousness, seizure, and stroke were the most common reasons for NILs. Half of the patients had acute neurological diseases warranting immediate diagnosis and treatment by the consulting neurologists. Balancing increasing neurologist workloads and appropriate health-care resources remains a challenge.

Purpose: Some patients with respiratory failure fail initial weaning attempts and need prolonged mechanical ventilation (MV). Prolonged MV is associated with many complications and consumption of heathcare resources. Objective weaning indices help staffs to identify high-potential patients for weaning from the MV. Traditional weaning indices are not reliable in clinical practice. Transitional percentage of minute volume (TMV%) is a new index of the work of breathing. This study aimed to investigate the utility of TMV% in the prediction of weaning potential. Methods: This study was prospectively performed including all patients with prolonged MV. Researchers recorded their demographics, TMV%, respiratory parameters, Acute Physiology and Chronic Health Evaluation II score, and laboratory data upon arrival at the respiratory care center. The factors associated with successful weaning were analyzed. Results: Out of the 120 patients included, 84 (70.0%) were successfully weaned from MV. Traditional weaning indices such as rapid shallow breathing index could not predict the weaning outcome. TMV% was a valuable parameter as patients with a lower TMV%, higher tidal volume, higher hemoglobin, lower blood urea nitrogen, and lower Acute Physiology and Chronic Health Evaluation II scores had a higher rate of successful weaning. TMV%, tidal volume, and HCO3- levels were independent predictors of successful weaning, and the area under the curve was .79 in the logistic regression model. Conclusion TMV% is a novel and effective predictor of successful weaning. Patients with lower TMV% had a higher MV weaning outcome. Once patients with a high potential for successful weaning are identified, they should be aggressively weaned from MV as soon as possible.
