Objective To evaluate the clinical application of enzyme-linked immunospot(ELISPOT) assay for detection of M.tuberculosis antigen specific T cells in the rapid diagnosis of active tuberculosis.Methods Using the rapid enzyme-linked immunospot assay for detection of T cells with secretion of IFN-? specific for M.tuberculosis antigens in blood samples from 112 patients with tuberculosis, 24 patients with hepatitis C, 30 healthy persons, and 65 with other respiratory diseases.Results 107 of 112 tuberculosis patients had detectable M. tuberculosis antigen-specific T cells, whereas 2 of 30 healthy subjects and 65 patients with non-tuberculosis illnesses responded. This assay has a sensitivity of 95.5%, specificity of 93.3%.Conclusions M.tuberculosis specific T cells could serve as accurate markers of M.tuberculosis infection in an area of high tuberculosis prevalence.ELISPOT is a rapid, sensitive and specific method for detecting M.tuberculosis specific T cells.It also gives objective evidence to the diagnosis of active tuberculosis.

Objective To understand the bacteriology and the association between drug susceptibility and clinical features from recent hospitalization of tuberculosis(TB)patients with positive tuberculosis bacilli culture.Methods We collected the clinical data of inpatients due to tuberculosis or pulmonary disease with positive tuberculosis bacilli by BACTEC960 culture auto-analysis system and possessing anti-tuberculosis drug susceptibility testing results from January 2008 to November 2008.All isolated strains were tested with first-line drugs included Streptomycin(S),Isoniazid(H),Rifampicin(R)and Ethambutol(E).Some isolate strains were used to test Amikacin(Am),Capreomycin(Cm)and Ofloxacin(Ofx).We recorded the drug-tested results and clinical data and retrospectively analyzed them.The patients with pulmonary disease from nontuberculosis mycobacteria(NTM)were excluded.Results (1)There were 417 patients with positive culture of tuberculosis bacilli (included 294 male and 123 female).The mean age was(47.8 18.1)years(ranging from 6 to 91 years).There were 68 cases complicated with endobronchial tuberculosis(EBTB)and 56 cases with type 2 diabetes mellitus.(2)There were 271 cases for initial treatment and 146 cases of relapsing tuberculosis.The total drug resistant rate was 53.5 percent,and of oflx was as high as 31.86 percent.The initial drug resistant rate was S 22.5%,H 25.8%,R 17.3%,E 21.0%,Am 6.3%,Cm 10.0%,Ofx 16.6% respectively and the required rate was 67.8%,82.9%,68.5%,68.5%,19.9%,25.3%,58.2% respectively.(3)There were 143 patients with multi-drug resistant TB(MDR-TB).The mean age 44.59?16.31 was significantly younger than of other patients(P

AIM: To construct subtractive libraries in association with heat adaptation differential expressed genes. METHODS: The experiment was carried out with heat adapted rat model and normal temperature control. mRNA was extracted from liver tissue and reverse-transcripted into cDNA. After cut and ligation, suppression subtractive hybridization was executed with each group of cDNA as tester and the other one as driver to construct subtractive libraries. Specificity of the libraries was evaluated by approach of comparing G3PDH gene PCR products with template from the library and unsubtractive sample. Reliability of the libraries was evaluated by primarily isolation and screening. RESULTS: PCR results confirmed that G3PDH concentration was greatly reduced compared with control group, which suggested that specificity of the libraries was high. 300 target segments were isolated from the library, 27 of them were verified to be differential expressed genes, which suggested that the libraries were reliable and efficient. CONCLUSION: This study founded the basis of further investigation on heat adaptation mechanism by approach of constructing subtractive libraries in association with heat adaptation differential expressed genes.

Objective To observe effects of ganoderma lucidum triterpenoids(GLT) on learning and memory function and anti-oxidative ability of aging model mice induced by D-galactose. Methods Senile model mice were established by D-galactose hypodermic injection for 8 weeks.GLT had been administered to two therapy groups.All the mice of different groups were tested with Morris water maze.Then the mice were killed and biochemically assayed of total anti-oxidative capacity(T-AOC),superoxide dismutase(SOD) and malondialdehyde(MDA) in the brain. Results The model mice showed worse ability in learning and memory in comparison with control mice.The T-AOC activity and SOD activity in the brain decreased and the MDA content increased in model rats in comparison with control.GLT significantly improved the changes mentioned above. Conclusion GLT improved the learning and memory dysfunction in aging model mice by modulation of the anti-oxidative ability.

OBJECTIVETo discuss the therapeutic effect of thenar perforator flaps for the narrow cicatricial contracture at thumb and the first web.

METHODSFrom Aug. 2010 to Jan. 2012, 9 cases with narrow cicatricial contracture at thumb and the first web, were treated. The defect size after releasing the contracture ranged from 8 mm x 20 mm to 15 cm x 30 mm. The bilateral thenar perforator flaps beside the wound were designed which size was 10 mm x 25 mm to 15 mm x 35 mm. The wounds at donor sites were closed directly.

RESULTSAll the 9 flaps survived completely with primary healing. The patients were followed up for 6-18 months. The flaps had soft texture and good appearance. The shape of flaps and function of the fingers were satisfied after 6-18 months of follow-up. There was no scar contracture at incisions in thenar. The thumb motion was really normal. The abduction of first web was 70 degrees - 90 degrees degrees.

CONCLUSIONSThe thenar perforator flaps is one of the ideal methods for the treatment of narrow cicatricial contracture at thumb and the first web. The main artery is not sacrified.

Objective To study the changes in serum adiponectin level in children with severe sepsis,and to explore its clinical significance.Methods A prospective study was conducted,and 39 cases of critically ill children with severe sepsis and 47 cases of sepsis were enrolled into the Pediatric Intensive Care Unit(PICU),Children's Hospital of Nanjing Medical University from July 2012 to July 2014.Thirty cases of critically ill children without sepsis were enrolled as a control group.The plasma adiponectin,procalcitonin(PCT),and C-reactive protein(CRP)were determined with enzyme linked immunosorbent assay(ELISA)within 24 hours after PICU admission.The pediatric critical illness score(PCIS)was recorded.Results Among severe sepsis group,sepsis group and control group,there was no statistical significance in body temperature,heart rate,body mass index,PCIS,white blood cell count,platelet count,bilirubin,creatinine,pH value and activated partial thromboplastin time(APTT)(all P>0.05).Plasma adiponectin in the severe sepsis group[(0.102±0.041)mg/L] significantly decreased compared with that in the sepsis group[(0.125±0.046)mg/L] and the control group[(0.147±0.047)mg/L](F=8.456,P=0.000).The level of CRP in the severe sepsis group[(60.68±59.43)mg/L] significantly increased compared with that in the sepsis group[(52.76±26.67)mg/L] and the control group[(33.89±6.87)mg/L](F=17.416,P=0.000).There was a statistical significance in PCT level in the severe sepsis group,the sepsis group and the control group(x2=27.269,P=0.000).Further comparison showed that there was a significant difference in PCT level between the severe sepsis group and the sepsis group(Z=-4.679,P=0.000),which was also statistically significant between the severe sepsis group and the control group(Z=-4.244,P=0.000);there was no significant difference between the sepsis group and the control group(Z=-0.340,P=0.733).Negative correlation was found between plasma adiponectin and CRP(r=-0.219,P=0.042),PCT(r=-0.303,P=0.005).The correlation between plasma adiponectin and PCIS was positively correlated(r=0.332,P=0.002).Conclusions Plasma adiponectin decreased in severe sepsis children and was significantly associated with the severity of the disease.Detection of plasma adiponectin levels in children with sepsis has an important clinical significance in evaluating the severity of sepsis.Plasma adiponectin is negatively correlated with CRP and PCT,and plays a role in diagnosis of infection.

OBJECTIVETo study and compare the therapeutic effects of electroacupuncture and probiotics combine Deanxit in treating diarrhea predominant irritable bowel syndrome (D-IBS).

METHODSTotally 64 D-IBS patients accompanied with anxiety and/or depression were randomly assigned to the Western medicine group (Group A) and the electroacupuncture (EA) group (Group B), 30 patients in Group A and 34 patients in Group B. Patients in Group A took Bacillus licheniformis and Deanxit, while those in Group B received EA. Four weeks consisted of one therapeutic course. Three-month follow-up was carried out. The scoring for the digestive tract symptoms, HAMA score, and HAMD score were evaluated before and after treatment. The recurrence in the 3-month follow-up was also observed.

RESULTSThe total effect rate was 86.67% in Group A and 88.24% in Group B with no statistical difference between the two groups (P > 0.05). There was statistical difference in the scoring for the digestive tract symptoms, HAMA score, and HAMD score (P < 0.05, P < 0.01). There was no statistical difference in the improvement of defecation frequency score, HAMA score, HAMD score between the two groups after treatment (P > 0.05). Better effects on improving abdominal pain score and abdominal distention score was obtained in Group B (P < 0.01), while better effects on improving the stool form score and mucus score were obtained in Group A (P < 0.01). There was no statistical difference in the recurrence rate between the two groups within the two-month follow-up (P > 0.05). The recurrence rate within the 3-month follow-up was obviously lower in Group B than in Group A (P < 0.05).

CONCLUSIONSEA and Western medicine (probiotics combined Deanxit) could effectively treat D-IBS patients accompanied with anxiety and/or depression. Both of them had different superiorities in improving symptoms. But EA had better long-term therapeutic effects.
