Objective To analyze the epidemiological characteristics of Mycobacterium tuberculosis by enterbaeterial repetitive intergenic consensus-polymerase chain reaction(ERIC-PCR)DNA fingerprint. Methods Mycobacterium tuberculosis positive sputum samples between September 2003 to May 2006 were collected and cultured.Chromosomal DNA were extracted and ERIC-PCR DNA fingerprinting was analyzed by software,such as RAPD PHYLIP and Treeview.Results A total of 42 different fingerprints were detected.Phylogenetic analysis showed that they could be classified into three clusters,the clustering rate was 72.6%.The characteristics of ERIC-PCR fingerprint patterns were related to age,drug resistance,and type of resistance.Conclusions ERIC-PCR DNA fingerprinting technique used in this study is good for epidemiological studies with its strong discrimination,simplicity and rapidness.A high level of recent transmission is found in our city.

Objective To observe the effects of Wendan decoction (WD) on depression-like behavior in a rat model of Parkinson's disease (PD) and explore the related mechanism.Methods Rodent model of PD was established by unilaterally lesioning medial forebrain bundle with 6-hydrodopamine.After intragastric administration with WD,the rats's behavior changes were detected by the open field test,sucrose preference test and forced swimming test;the contents of monoamine neurotransmitters in the rat brain were assessed by high-performance liquid chromatography with electrochemical detection.Results Compared with those of sham-operated rats,the horizontal and vertical activities of the PD model rats decreased significantly,and sucrose consumption decreased significantly,but immobility time during forced swimming was significantly prolonged.The contents of dopamine (DA),5-hydroxytryptamine (5-HT) and noradrenaline (NA) in the medial prefrontal cortex (mPFC) and DA in the striatum decreased significantly.After administration of WD for 2 weeks,the immobility time of the PD model rats was significantly decreased,sucrose consumption increased significantly;DA,5-HT and NA levels in the mPFC increased significantly.Conclusion WD improves the depression-like behavior in PD model rats,and the mechanisms may involve the regulation of monoamine neurotransmitters in mPFC.

Objective To evaluate the overall effect of transsphenoidal microsuegery for 23 patients with non-adenomas disease intrasellar region.Methods A toal of 23 patients with non-adenomas disease in- trasellar region,7 cases of Rathke's cleft cyst,3 cases of craniopharyngiomas,2 cases of meningiomas,2 ca- ses of pituitary tuberculous granuloma,5 cases of pituitary abscess,2 cases of empty sella,2 cases of chord- mas,were treated via sublabio-septo-sphenoidal microsurgery.Results There were among the 23 patients, groos total removal of the disease were achieved in 14 cases,subtotal removal in 7 cases,and partial removal in remain 2 cases.Diminished visual activity and visual field defects were improved in 13 cases.Menstrual disorder in all female cases and sexual disturbance in male were improved.There was no death in group. Conclusion Microsurgical technique via transsphenoidal approach is a safe and effective one for the treatment of patients with non-adenomas disease intrasellar region.

Objective To analyse the risk factors for lymph node metastasis of early colorectal cancer and the therapeutic indication for endoscopy.Methods The clinical data of the 269 early colorectal cancer patients who underwent surgical treatments between January 2009 and December 2013 in the West China hospital of Sichuan University were analyzed retrospectively.Pathologic features were compared between different histological types and investigated by univariate and multivariate analysis of their possible risk factors for lymph node metastasis.Results Univariate analysis showed that tumor size (P =0.029),depth of tumor invasion (P =0.006),histological type (P =0.000) and lymphatic involvement (P =0.035) were correlated with lymph node metastasis.Multivariate analysis revealed that tumor size (OR =5.385,95％ CI:1.156-25.075,P =0.032)and histological type (OR =5.145,95％ CI:1.553-17.053,P =0.007) were independent risk factorsfor lymph node metastasis.Comprehensive analysis showed that lymph node metastasis could not be found in patients with tumor invading the mucous layer.However,lymph node metastasis occurred if the tumor invaded the submucous layer.The larger and less differentiated tumor was,the higher occurrence of lymph node matastasis would be (P ＜ 0.05).Conclusion Endoscopic resection is recommended for those with early colorectal cancer localized in the mucous layer and without lymph node metastasis.It is recommended that patients with submucosal carcinomas undergo a preoperative endoscopic ultrasonography or pathological screening for the most appropriate surgical treatment,as the larger and the lower differentiated the tumor is,the higher chance the lymphatic metastasis is.

[ABSTRACT]OBJECTIVETo investigate the diagnosis, treatment method, key points of operation, and postoperative complications of high-risk esophageal foreign body.METHODSA retrospective analysis of 41 cases of high-risk esophageal foreign body from January 1996 to December 2014. After adequate preparation, the foreign body was removed via esophageal endoscope under general anesthesia.RESULTSThe foreign bodies in 41 patients were removed via esophageal endoscope once or twice. Two cases suffered postoperative subcutaneous emphysema, that may be a result of a small perforation in esophagus. Emphysema was disappeared by fast, rehydration and anti-infection for 6 to 8 days, and other serious complications did not occur.CONCLUSIONMost high-risk esophageal foreign bodies can be removed through rigid esophagoscopy. Some of the foreign bodies of the patients were difficult to remove, some patients were presented with mediastinal emphysema and pneumothorax due to esophageal perforation, and some foreign body stuck in oesophagus so long to cause esophageal mucosa ulcer. In these conditions, foreign bodies should be removed by lateral neck incision or thoracotomy.

Objective To investigate the changes of blood levels of gastrin(GAS),motilin(MTL) and insulinoid growth factor-1(IGF-1) in critical children with multiple organ disfunction syndrome(MODS).Methods The levels of GAS,MTL and IGF-1 in 50 critically ill children and 30 children without critical illness were detected.The control group consisted of 30 health children.All serum or plasma levels of GAS,MTL and IGF-1 were measured by radioimmunoassay.Results The serum or plasma levels of GAS,MTL and IGF-1 were significantly higher in critically ill children than those in uncritically ill children and control group(F=49.61,55.18,18.23 all (P

Objective:To observe the change of periphery and centra lymphocyte subsets at the crest-time of MOG_(35-55) induced EAE disease in mice,and to explore the alteration of cellular immunity and humoral immunity in the invasion process in EAE.Methods:MOG_(35-55) was used to establish EAE model in femina C57BL/6 mice.The behavioral changes and the histological scores were recorded after the mice were immuned .The changes of CD3~+CD4~+,CD3~+CD8~+,CD4~+CD25~+ and B220~+ on periphery and centra lymphocytes in spleen,brain and spinal cord were analyzed by flow cytometry.Results:The CD3~+CD4~+,CD3~+CD8~+,CD4~+CD25~+ and B220~+ lymphocytes were detected in the brain and spinal cord of EAE group mice,but they were not detected in CFA control group.The CD3~+CD4~+ and CD3+CD8+lymphocytes in the spleen of EAE crest-time group were lower than those in CFA control group(P＜0.05).The B220~+ lymphocytes were obviously higher than in the CFA control group (P＜0.01).And CD4~+CD25~+ lymphocytes were slight higher than the CFA control group.Conclusion:At the crest-time during EAE,the CD3~+CD4~+,CD3~+CD8~+lymphocytes of spleen reduced obviously,B220~+ lymphocytes increased markedly,and the CD4~+CD25~+ lymphocytes just have the increasing trend.It indicates that cellular immunity and humoral immunity coregulated the patho-process at the crest-time of EAE,T lymphocytes and B lymphocytes all played important roles in the pathogenesy of EAE.
