Objective To investigate the causes, diagnosis and treatment of gastrolienal portal hypertension. Methods During recent 10 years, 32 cases of gastrolienal portal hypertension were admitted. Clinicopathological features were analyzed. Results The main causes of this entity was chronic pancreatitis or pseudocyst of the pancreas (14 cases), tuberculosis of lymph nodes in retroperitoneum (7 cases) , retroperitoneal malignant lymphoma (3 cases) and pancreatic tumors (8 cases). Definite diagnosis was made in all 32 cases during the hospitalization. Twenty cases underwent surgery including splenectomy (11 cases) , splenectomy plus portal-azygous disconnection (5 cases) , splenectomy plus distal pancreatectomy (4 cases) , endoscopic varicose vein ligation combined with partial splenic embolization (2 cases), and endoscopic varicose vein ligation ( 5 cases). Conclusion A definite diagnosis of gastrolienal portal hypertension lies in the surgeon's recognition of this entity. Splenectomy is the most effective symptomatic treatment.

AIM:To discuss Daidzein intravitreal injection whether has protective and recovery effects on acute nerve damages.
METHODS:After the crush models of acute optic nerve were set up, 72 males SD rats were divided into 4 groups randomly as common group without surgery, FBS negative control group, Daidzein treatment group ( 10μmol/L, 100μmol/L, 1000μmol/L ) and positive control group using rats nerve growth factor ( mNGF, 100ng/mL ). Three days after interference, all experimental animals were executed. HE staining was used to evaluate morphologic change of the retina, immunohisochemical staining and western-blot tests for identifying and quantifying the distinct expression of Caspase-3 and GAP-43 among the groups.
RESULTS: Compared with the normal group and negative control group, retinal morphology of different concentrations of each Daidzein treatment group and positive control group was more complete, the expression of Caspase-3 protein was relatively lower, the expression of GAP-43 protein was relatively higher, the differences have statistically significance (P<0. 05).CONCLUSION: Daizein injection in the vitreous cavity has the capacity of protection and restoration in rat's acute nerve damages.

One type of important plant disease resistance, gene-for-gene resistance, is resulted from the interactions between products of the pathogen avirulence (Avr) genes and their matching plant resistance (R) genes. Avr genes have been cloned from a variety of pathogens including fungi, bacteria, viruses and oomycetes. No significant homology is found between sequences of the most cloned Avr genes and those of known proteins or between those of themselves. However, significant homology has been found between sequences of the cloned R genes and those of known proteins or between those of themselves. R proteins consist of similar domains. It has been reported that hypersensitive cell death and resistance, which are induced by interactions between products of different Avr/R gene pairs consisting of similar R genes but different Avr genes, are distinct in development speed, strength, and organ and tissue specificity. Avr genes have dual functions: Pathogens containing Avr genes are avirulent to plants carrying the matching R genes, while they are virulent in race, strain, pathovar or species-specific way to plants without carrying the matching R genes.

Aim The expression of NF-?B activation and the effect of antioxidant (N- acetylcysteine, NAC) on NF-?B activity in human airway epithelial cell was assessed. Methods Using the TNF-?,the airway epithelial cell strains of normal subject(16HBE) and tumor patient (H292) was activated and using Western-Blot and ELISA the expression of NF-?B and IL-8 were detected. Results It was found that the activity of NF-?B could be stimulated by the TNF-? and increase with the amount of TNF-? with the peak occurring at 2 to 4 hours after stimulation and then decreasing at six hours. At the same time, the level of IL-8 was elevated, but decreased with inhibition of NF-?B activity by NAC, that means the action of NAC has a dose-dependent effect. Conclusion NAC not only blocks the signal transmission activated by NF-?B, but also anticipates the transcription modulation of expression of many cell factors and inflammatory mediums. It suggests that NAC may play a role in the anti-inflammatory treatment of respiratory diseases.

Objective To discuss the clinical significance of postoperative application of gastrointestinal decompression after anastomosis of lower digestive tract. Methods Three hundred and sixty-eight patients undergoing excision and anastomosis of lower digestive tract were divided into two groups: the group with postoperative gastrointestinal decompression and the group without it. The clinical therapeutic outcomes and incidences of complications were compared between the two groups. Results The volume of gastric juice in the decompression group was about 200 ml every day after operation. Both groups had a smaller abdomenal circumference before operation than after operation ( P

Three hundred and twenty-one bacteria strains were obtained from rice leaves,stem,root tissue and paddy field soil,of which the number of strains which can inhibit mycelium of Magnaporthe grisea growth markedly was fifty-seven through fermentation in 2.0 mL Eppendorf tube,and among these fifty-seven strains,five strains were strongly antagonistic to Magnaporthe grisea.These five strains was identified for their morphologic,physiological and biochemical characteristics,and the results showed that one strain(No.156)was bacillus subtilis,two strains(No.171 and No.177)were Bacillus pumillus and two strains(No.192 and No.279)were Bacillus ploymyxa.

OBJECTIVE: To repair the postoperative tissue detect of the base of tongue cancer in advanced patients. METHOD: There were 30 patients of medium-high differentiation squamous cell carcinoma(SCC) included in this study. According to the TNM staging of AJCC 2002, there were 4 cases of T2N1M0, 7 of T3N1M0, 10 of T3N2M0, 4 of T4N1M0 and 5 of T4N2M0. Surgical approach of the primary lesion: 12 with transhyoidpharyngotomy approach and 18 with mandibulotomy approach. All cases accepted radiotherapy 4-6 weeks after surgery. RESULT: Twenty-five cases were reconstructed with pedicle pectoralis major myocutaneous flaps, and all them survived. Among them, 1 flap was partial split with surrounding tissue spontaneously, and another flap had partial tissue necrosis, however, both flaps grew well with dressing and other local treatment. Other 5 cases were reconstructed with free anterolateral myocutaneous flaps. Among them, 1 flap had partial tissue necrosis, but had a secondary healing after removing necrotic tissue via mouth approach. All 18 patients of larynx-preservation had tracheal tube pulled out. The 3-year survival rate was 68% and the local control rate was 87%. CONCLUSION Pedicle pectoralis major myocutaneous flaps and free anterolateral myocutaneous flaps were alternative donor area for repairing postoperative tissue defect of the base of tongue; The former was preferred, and the latter was concealed so as to be a kind of effective method, which need adept technique of microsurgery.

Objective To study the value of endoscopic submucosal excavation (ESE) for esophageal submucosal tumors originating from the muscularis propria layer.Methods Data of 27 patients with 29 lesions in esophageal muscularis propria treated with ESE from Dec.2008 to Dec.2010 were retrospected.Feasibility,effects and safety were evaluated accordingly.Results Of 27 patients,there were 17 males and 10 females.Mean age was 50(22 ～62)yrs,and mean diameter of the lesions was 1.25 ±0.70 (0.5 ～3.0)cm.Resection rate was 96.3％ (26/27).One failed case with tumor residual after ESE received additional operation.The median procedure time was 74 (30-120) min.Pathological examination confirmed leiomyoma in 26 cases and gastrointestinal stromal tumor (GISTs) in 1 case.Perforation during operation occurred in 2 cases,accompanied with pneumothorax.They were treated with closed thoracic drainage,without surgery.The median follow-up time was 12 months (3 to 27 months),and no recurrence was found.Conclusion ESE is a safe and effective therapy for the esophageal tumor smaller than 3.0 cm from the muscularis propria.

AIM: To clarify the role of Cl - in regulatory volume decrease (RVD) of nasopharyngeal carcinoma cells (CNE-2Z).METHODS: Analysis of living cell images was used to detect the volume changes following exposure to hypotonic solution. Iron replacement and block of iron channels were also applied in the present study. RESULTS: Extracelluar hypotonic treatment made the cells swell and induced RVD. The RVD was correlated positively to the swelling in the range of 160-230 mOsmol/L. Substitution of gluconate for Cl - in perfusing solutions markedly increased RVD. Depletion of cellular Cl - abolished, and chloride channel blockers inhibited RVD. CONCLUSION: Cl - is the key iron to establish the RVD in CNE-2Z cells. Activation of Cl - channels and Cl - efflux are the major mechanisms of RVD.
