Objective To evaluate the effect of endoscopic ultrasonography(EUS)in diagnosing e- sophageal and gastric varices in portal hypertension(PHT)patients.Methods Fifty-three patients with e- sophageal and gastric varices(EV、GV)of decompensation PHT and 20 patients without PHT as control were undergone EUS and esophagogastroduodenoscopy(EGD)simultaneously.EUS detected mainly the EGV,e- sophagus and stomach collateral veins.Results EUS identified EV endoscopically in 29(54.7%)patients. EUS detected GV in 24(45.3%)patients,compared with detection in 18(34.0%)patients by esopha- gogastroduodenoscopy(EGD)(P＜0.001).EUS detected PEV in 27(51%)patients.Distribution rates of PEV in F1,F2 and F3 are 0%,28.6% and 75% respectively.The comparison between groups shows sig- nificant difference(P＜0.001).Splenic vein can be seen in both control and experimental groups with di- ameter 7.5?1.35mm VS 11.5?3.5mm respectively,the difference between two groups is significant(P＜0.001).Proximal diameters of Azygos vein in two groups is 7.36?1.29mm VS 8.77?2.94mm respective- ly.Significant difference can be found(P＜0.05).Conclusion EUS had significant value in the diagnosis of PHT with EV and GV,and especially in detecting abnormalities of extra-luminal veins.

Objective Probing into the primary healthcare capabilities of healthcare clinics in the four provinces in China's west,in order to recommend the government in making relevant policies.Results It is found that among those village doctOrs under 45 years of age,76.0%have senior high school diploma/secondary technical school education,89.6%have rural doctor certificates;those above 45 years old,59.5%have middle school education,96.9%have rural doctor certificates,and 1.6%have licensed assistant doctor certificates.x2check is statistically significant,as the village doctors born in different eras have different composition of education and different percentage of qualification certificates.44.44% of the village clinics have less than three rooms,and 41.11%occupy less than 40 square meters.Only 19.44%of the clinics receive funding for their medieal facilities from higher authorities.Conclusion It is imperative to enhance resources input tO the staff and facilities of village clinics in the west,to cater to the primary healthcare needs of the local people.

Objective To comprehensively know clinical pathological change of recurrent anterior dislocation of shoulder joint by arthroscopy. Methods 52 patients with recurrent anterior shoulder dislocation were inspected by arthroscopy in our institute, 38 cases were male, 14 cases were female; the mean age were 24.7, from 16 to 49 years old. 2 epilepsy patients were excluded, the other 50 cases were divided into two groups, the first group included 32 shoulder dislocated patients accompanied with shoulder hyper-laxity. The other group included 18 purely traumatic shoulder dislocated patients. All patients were explored by arthroscopy and all pathological changes were recorded and the difference of pathological change between the two groups were contrasted. Results 51 cases showed anterior-inferior labrum injury, 50 cases showed Hill-Sachs injury, 32 cases showed biceps-tendon inflammation or injury, 30 cases showed bone or cartilage injury of anterior-inferior glenoid, 29 cases showed SLAP injury, 7 cases showed rotator cuff injury. Anterior-inferior labrum injury: labrum abraded disappear was more occurred in pure traumatic group(P=0.055) and ALPSA injury was more in hyper-laxity group (59.4% to 38.9%, P=0.164). Bone or cartilage injury of anterior-inferior glenoid were more occurred in purely traumatic group(P=0.083, P=0.052). Hill-Sachs injury was more superficial or only cartilage injury in hyper-laxity group but wider and deeper in purely traumatic group. Conclusion The general pathological changes of recurrent anterior shoulder dislocation sucessively are: anterior-inferior labrum injury, Hill-Sachs injury, biceps-tendon inflammation or injury, bone or cartilage injury of anterior-inferior glenoid, SLAP injury and rotator cuff injury. The pathological changes of the hyper-laxity group were lighter than purely traumatic group.

Fifty three Wistar rats were randomly divided into healthy control group, COPD model group and NAC group, PKC inhibitor H7 intervention group and TGF ? monocolonal antibody group(TGF ? MA group).To study the role of matrix metalloproteinases(MMPs) and the tissue inhibitor of MMPs(TIMP 1) in the airway extracellular matrix(ECM) remodelling of COPD rat models and to observe the effects of NAC, H7 and TGF ? MA intervention on the regulation of MMPs and TIMP 1 and on ECM remodelling of the airway walls. Compared with control group, the airway collagen, the hydroxyproline(Hy) content of lung homogenates ,the number of fibroblasts(Fb) , the protein and/or mRNA expressions of MMP 2, MMP 9, TIMP 1 and TGF ? Ⅰ, Ⅱ receptor and the enzyme activities of MMP 2 (72kD), MMP 9 (92kD) were significantly increased in COPD model group. In all the drug intervention groups, the expressions of the above parameters were significantly decreased than those in model group except for Hy and Fb in H7 group, protein expression of TGF ? I receptor in NAC group and MMP 9 in TGF ? MA group. The results suggested that increased MMPs as matrix degrading enzymes might be responsible for the excessive degradation of ECM in airway, whereas incresed TIMPs might promote excessive ECM synthesis and deposition. The imbalance of MMP 9/TIMP 1 was related to the airway ECM remodelling. An antioxidant NAC and TGF ? MA might regulate the MMPs/TIMP 1 expression and reduce the airway fibrosis.H7 had strong collagenase inhibitory action,resulting increse in Hy and Fbs. The data may be helpful for searching effective prevention and treatment of airway ECM remodelling.

Objective: To investigate the influence and mechanism of zinc toxicity on the stucture and function of immune organs in ducks. Methods: By establishing the pathological model of zinc toxicity in ducks, some immunological methods, light and electron microscopes were used to check the changes in the stucture and function of immune system. Results: (1) The body weight of ZT group was significantly lower than that of ZC group after 3 weeks (P

Objective To study the expression of hepatocyte growth factor (HGF) in placenta from normal pregnancy and pregnancy induced hypertension (PIH) and the effect of HGF on angiogenesis in placenta. Methods Immunohistochemistry was used to determine the location and intensity of HGF staining in placenta from 20 cases of normal pregnancy and 58 cases of mild,moderate and severe PIH groups. HE staining was used in order to count the number of the vessles. Results HGF mostly were expressed in villous core mesenchymal cells,less in decidual cells . Intensity of HGF immnostaining in villous mesenchymal cells was significantly reduced in the severe PIH group compared with the normal group(H=7.395,P=0.003),while there were no statistical differences between the mild,moderate PIH group and the normal group (H=0.869,P=0.351,H=0.017,P=0.896) .The count of vessels reduced in severe PIH (F=10.676,P=0.008). There was positive correlation between the expression of HGF and the count of vessels in villous(r=0.246,P=0 030). Conclusion These results suggested that HGF is secreted mainly by villous core mesenchymal cells in human placenta and the reduction of HGF in PIH may be responsible for the impaired vascularization in PIH.
