Objective To assess the application of the phage amplified biologically assay (PhaB) in the detection of the mycobacterium tuberculosis (TB) in sputum.Methods To determine the TB patients in the 53 suspected patients we detected 53 sputum samples by PhaB method,BACTEC MGIT960 rapid culture method,and conventional methods (direct auramine smear microscopy and concentrated auramine smear microscopy) individually.Results TB positive samples detected by PhaB,BACTEC MGIT960 rapid culture,direct auramine smear microscopy and concentrated auramine smear microscopy were 24,22,11 and 17 respectively.Thus the sensitivity,specificity,positive predictive value and negative predictive value were 86.4%,83.9%,79.2% and 89.7%,when the PhaB is combined with concentrated auramine smear microscopy,the sensitivity,specificity,positive predictive value and negative predictive value were increased up to 90.9%,83.9%,80.8% and 92.9%.Conclusion PhaB method is a simple and rapid method to detect the Mycobacterium Tuberculosis in sputum with a relatively higher sensitivity and specificity than the conventional methods.When combined with concentrated auramine smear microscopy,PhaB method is even more sensitive.Thus the PhaB method is accessible and applicable in the clinical use of the TB detection.

Objective To investigate the correlation between the expression changes of brain-derived neurotrophic factor (BDNF) in colon mucosa and abdominal pain in irritable bowel syndrome (IBS). The density of nerve fiber in colon mucosa and ultrastructural alterations of nerve fiber in IBS were also observed. Methods From September 2008 to January 2010,the IBS patients who visited the department of gastroenterology of our hospital and met the Rome Ⅲ diagnosis criteria were selected and divided into IBS with diarrhea (D-IBS) and IBS with constipation (C-IBS) according to their clinical features. The patients with colon polyps detected by colonoscopy in our hospital were selected as control group. All subjects were asked to fill in Self-Rating abdominal pain or abdominal uncomfortable Scale according to abdominal symptom in the last 2 weeks before visit and underwent colonoscopy. Four biopsy specimens were taken from the colon mucosa of rectosigmoid junction. Ofwhich,two specimens were for protein isolation and detection of BDNF expression level,one specimen was used for PGP 9. 5 immunohistochemistry staining in paraffin slices. Another specimen was used to observe the ultrastructure changes of nerve fiber in colon mucosa under transmission electron microscopy. Results Total 40 IBS patients were enrolled in this study,of those 21 were D-IBS patients,19 were C-IBS patients,and 21 were controls. The abdominal pain severity score and frequency score of IBS patients were (2. 3±0. 8) and (2. 1±0. 7),which were significantly higher than those of control group (0. 4±0. 7 and 0. 3±0. 5,P＜0. 001). Compared with the control group,the BDNF expression in colon mucosa was significantly elevated in IBS patients (P= 0. 003 ),and which correlated with the severity and frequency of abdominal pain/discomfort (r=0. 57,P＜0. 001and r=0. 46,P= 0. 003,respectively). The immunohistochemistry result indicated that the nerve fiber density in colon mucosa of IBS patients was significantly higher than that of controls,and there were ultrastructural changes of colon mucosal nerve fibers in IBS patients. Conclusion Increased colon mucosal BDNF expression may be associated with abdominal pain symptom in IBS patients. The impaired ultrastructural of mucosal nerve fibers may cause the increased BDNF expression in colon mucosa,and result in the increased mucosal nerve fiber density in IBS patients.

High-speed counter-current chromatography (HSCCC) was used to high performance separate and prepare lignans from Schisandrae chinensis fructus. The solvent system is composed of n-hexane-ethyl acetate-methanol-water (9 : 1 : 5 : 5) and n-hexane-ethyl acetate-methanol-water (9 : 1 : 9 : 5), speed is at 900 r.min-1, and flow rate is at 2.0 mL.min-1. Five fractions from Schisandrae chinensis fructus extract were separated and prepared with one HSCCC process. They were identified as schisandrin, gomisin J, schisandrol B, schisantherin A and deoxyschizandrin by electrospray ionization-multiple tandem mass spectrometry (ESI-MSn), respectively. Their contents were obtained in 98.74%, 94.32%, 99.53%, 94.23% and 98.68% by ultra high performance liquid chromatography (UPLC), separately. The rapid and simple method can be applied for the preparation of lignans from Schisandrae chinensis fructus.

OBJECTIVE: Through the application of eustachian tuboplasty assisted with hypothermy plasma ablation, we evaluate its efficacy in the threatment of adult refractory otitis media with effusion. METHOD: We retrospectively reviewed the charts of 48 cases (61 ears) suffering from adult refractory otitis media with effusion from January 2012 to December 2013. According to the admission date, the patients were divided into the control group (17 cases, 22 ears) and the treatment group (31 cases, 39 ears). In the control group, the patients were treated with drugs and physical therapy. In the treatment group, the hypothermy plasma ablation technology was used to ablates the hypertrophic tissues around the eustachian orifice besides the pharmaedogical interventions. The recurrence rate of the two groups were analyzed and compared in 1 year after treatment. Pure tone audiometry and acoustic immittance measurement were taken for the two groups in differernt periods (one week prior to operation, one months, three months, six months and one year after operation respectively) to evaluate their hearing change and the recurrence rate (within six months after treatment and one year respectively) objectively. RESULT: In the control group, 2 cases (2 ears) were lost to follow-up, and the recurrence rate was 65% (13/20) in 1 year. In the treatment group, four case were lost to follow-up,and the recurrence rate was 14.3% (5/35) in 1 year. The difference was statistically significant (P<0. 01). There were similar hearing improvement in the two groups after treatment in 1 month, but the hearing improvement in the treatment group increased with time. There were no complications occuring during the operation and post-operation. Within a month after operation, the majority of ears(28/35) obtained significant hearing improvement with the decreasing air-bone-gap comparision with the pre-operation (P < 0.01), and the preoperative tympanogram of 16 ears with type B or C turned to type A (P < 0.01). There were no both statistical significance in the variation of air-bone-gap and tympanogram of comparison with results between three months and six months, six months and one year postoperatively (P > 0.05). CONCLUSION This study confirmed the efficacy of eustachian tuboplasty assisted with hypothermy plasma ablation in the threatment of adult refractory otitis media with effusion caused by eustachian tube opening disorder was significant. It can reduce the recurrence rate significantly in one year and allow sustained hearing improvement within three months postoperatively.
