Objective To analyze the surgical operation and prognosis of gastric stump carcinoma in elderly patients. Methods The clinical data of 25 cases of elderly gastric stump carcinoma in our department from 1993 to 2003 were analyzed retrospectively. Results In this group of cases, TNM stages Ⅰ, Ⅱ, Ⅲ and Ⅳ was 3, 5, 8 and 7 cases, respectively. Among them, radical resection was performed in 12 cases(48.0%), palliative operation in 9 cases(36.0%), exploratory laparotomy in 2 cases, and 2 cases lost the chance of resection due to extensive tumor dissemination. Nutritional jejunostomy was performed in all the cases received resection operation. 1, 3 and 5 years survival rates in the patients who underwent radical dissection were 81.2%, 41.5% and 28.6%, respectively. Conclusion Endoscopy examination plus gastric mucosa biopsy were major means for diagnosis of gastric stump carcinoma in elderly patients. Perioperative managements should be emphasized. Radical resection was a reasonable therapeutic procedure of elderly gastric stump cancer, and was also an important factor affecting prognosis.

Objective To investigate the causes of hernia recurrence after tension free inguinal hernioplasty and its prevention and treatment Methods The clinical data of 10 hernia recurrence cases were retrospectively analyzed Results There were 6 recurrent cases after mesh plug tension free hernioplasty and 4 cases after Lichtenstein repair The causes of recurrence included too small for size of the mesh, mesh was coiled and migrated, too large holes of mesh left for spermatic cord, mesh plugs not properly fixed, internal rings too large miss matching the mesh plug, two mesh plugs not mounted together, etc Conclusion The main causes of recurrent hernia after tension free inguinal hernioplasty were related with failure in applying correct operative techniques, the recurrence needs open mesh repair, especially mesh plug tension free hernioplasty

Purpose: To investigate the expression of Survivin gene and its relationship with expression of Caspase-3, B-cell lymphoma-2( Bcl-2) in human non-small-cell lung carcinoma( NSCLC) . Methods: Expression of the Survivin mRNA was evaluated by in situ hybridization (ISH) in 13 normal bronchial epithelium, 11 dysplasia, 54 NSCLC and 12 lymph node metastasis. Immunohistochemical assay was used to detect the expression of Caspase-3 and Bcl-2 proteins. Results: Expression of Survivin was detected in a significantly greater proportion in NSCLC (74. 07%) and lymph node metastasis (91. 67%) than normal bronchial epithelium (7. 69%) and dysplasia ( 27. 27%) (P

Objective To evaluate the value and limitation of MRI in the diagnosis of meningovascular neurosyphilis. Methods Five cases of neurosyphilis confirmed by clinical history/laboratory were examined with MRI (3 plain MRI, 2 enhanced MRI). The results of blood and CSF TPPA/RPR were positive and HIV was negative. Results Abnormal signals were demonstrated in the temporal lobe in 3 cases, and infarction was revealed in the basal ganglion and periventricular white matter in another 2 cases. There was no marked contrast enhancement in the 2 cases. Conclusion Meningovascular neurosyphilis has no characteristic features on MRI, but MRI is an effective method in delineating the size, range, and characters of neurosyphilis, and it is also an useful modality to follow-up after antibiotic therapy.

Objective To investigate the value of endoscopy in the diagnosis and treatment of biliary obstructions on different sites with variable causes. Methods The clinical records of biliary drainages under duodenoscope in 104 patients with biliary obstruction from October 1998 to November 2002 was reviewed retrospectively. Results Drainage was successfully completed in 97 patients, with a success rate of 93.3%(97/104). The patients were relieved of their symptoms of biliary obstruction (abdominal pain, jaundice and fever), and the effective rates of ENBD and ERBD were 93.0% (66/71) and 93.3% (28/30), respectively. Conclusions Endoscopic drainage for biliary obstruction has advantages of minimal invasion, rapid recovery, short hospital stay and apparent efficacy. Emphasis should be placed on the site of drainage and proper selection of operative method to further elevate its success rate.

Abstract: Objective　To investigate the composition and diversity of midgut microbial community of Haemaphysalis longicornis infected with severe fever with thrombocytopenia syndrome virus (SFTSV)． Methods　The midgut DNA of three group Haemaphysalis longicornis infected with SFTSV was extracted, and the 16S rDNA gene of the sample was sequenced by HiSeq platform. The composition and diversity of endosymbiotic microbial community were clarified by OTU cluster analysis and alpha diversity analysis. Results　The midgut microbial clusters of the three groups infected with SFTSV were 143, 113, 163 OTUs respectively; the sparsity curve and abundance grade curve showed that the data had sufficient sequencing depth, and the midgut of Haemaphysalis longicornis infected with SFTSV was rich in microbial composition, but the species distribution was uneven. The analysis of microbial community composition showed that Proteobacteria, Firmicutes and Actinobacteria were the main dominant bacteria at the phyla level. At the class level, Gammaproteobacteria, Bacilli, Betaproteobacteria and Actinomycetia were the main dominant bacteria. At the order level, Legionellales, Bacillales, Burkholderiales and Actinomycetales were the main dominant orders. At the family level, Coxiellaceae, Bacillaceae, Moraxellaceae and Rhodococcaceae were the main dominant families. At the genus level, the relative abundance of Coxiella was the highest, followed by Aeribaillus and Azonexus. Alpha diversity analysis showed that the average Shannon index was 139.67, the average Simpson index was 0.48, the average Chao index was 145.06, and the average ACE index was 147.11. Conclusions　The species diversity of intestinal microorganisms in Haemaphysalis longicornis infected with SFTSV is rich. The results provide a basis for further exploring the interaction between intestinal microbes of Haemaphysalis longicornis and SFTSV and developing new ideas for the prevention and control of ticks and tick-borne diseases.

Objective To observe the clinical efficacies of acupoint injection versus acupoint application in treating patients with chronic bronchitis due to lung-qi deficiency in remission stage.Method Totally 163 patients with chronic bronchitis were randomized into group A of 78 cases and group B of 85 cases. Group A was intervened by acupoint application, while the control group was by acupoint injection. The syndrome score of traditional Chinese medicine (TCM) was evaluated before and after treatment, the attack frequency of cold, quality of life, and pulmonary function were observed in the 6-month follow-up.Result The TCM syndrome scores were significantly changed after treatment in both groups (P<0.05). There was no significant inter-group difference in comparing the attack frequency of cold in the 6-month follow-up (P>0.05). The scores of quality of life (FS1, FS2, FS3, FS4 and TMS) in group A were significantly changed after treatment (P<0.05). The FS1 score in group B was remarkably changed after treatment (P<0.05). The parameters of pulmonary function (FEV1.0%, V50, V25, FVC, FEV1.0) were significantly changed after treatment in both groups (P<0.05).Conclusion Acupoint application and acupoint injection both can significantly improve the symptoms, quality of life, and pulmonary function in chronic bronchitis.
