ABSTRACT
Objective:To explore the construction and implementation effect of clinical-thinking patterned curriculum for parallel graduate students with "running through clinical diagnosis and treatment process."Methods:In this study, 94 Batch 2016-2017 graduate students with clinical medical professional degree in Shanxi Provincial People's Hospital were selected as the research subjects. Among them, 48 Batch 2017 parallel graduate students were selected as the experimental group. The curriculum of clinical-thinking patterned training of "running through the clinical diagnosis and treatment process" was used. In addition to participating in the degree courses and residency courses, a series of training to improve the clinical-thinking ability were introduced. And 46 Batch 2016 parallel graduate students were divided in the control group, using a traditional curriculum and only participating in degree courses and residency courses. The differences among mini-clinical evaluation exercise (Mini-CEX) scores, direct observation of procedural skills (DOPS) scores, objective structured clinical examination (OSCE) scores and students' satisfaction were compared by t test, chi-square test and repeated measures analysis of variance. Results:The Mini-CEX scores showed the average scores of other aspects except humanistic care were higher than those of the control group, and the score of communication skills was significantly higher than that of the control group [(6.55±0.98) vs. (5.77 ±1.12)], with significant differences ( t=3.62, P<0.001). In the DOPS scores, except for the skills of communication with patients, ability to consider patient's feelings and practice of occupational literacy, the average scores of other aspects of the experimental group were higher than those of the control group, and the real operation-ability score of clinical skills was significantly higher than that of the control group [(6.38 ± 1.38) vs. (5.53±1.23)], with a significant difference ( t=3.12, P=0.002). In terms of the outpatient receiving station, the emergency treatment station, the clinical thinking station①, the clinical thinking station②, the specialist skill station, the auxiliary examination station and the case writing station, their OSCE scores at different stages in the experimental group were higher than those in the control group, and in terms of clinical thinking station①, the score of the experimental group was significantly higher than that of the control group, with a significant difference ( F=6.51, P=0.012). The satisfaction rate of the experimental group in terms of curriculum was higher than that in the control group except for the future career development, and in improving logical-thinking ability, the score of the experimental group was significantly higher than that of the control group, with a significant difference ( χ2=19.18, P<0.001). Conclusion:The curriculum of clinical-thinking ability with "running through the clinical diagnosis and treatment process" can enhance the clinical practical ability of parallel graduate students, making them meet the residential academic standards as soon as possible and effectively promoting the training quality of the students.

ObjectiveTo evaluate the therapeutic effect of combined portoazygous devascularization and shunt on portal hypertension. MethodsThe data of 56 cases of portal hypertension treated with portoazygous devascularization and shunt from April 1987 to April 1999 was summarized. ResultsThere was no death in 54 patients receiving selective operation;of 2 cases receiving emergency operation, one died. Among 49 followed-up cases, there was one rebleeding,2 hepatic encephalopathy, and one died of liver failure 4 years after opeation. The mean portal pressure before and after operation was(3.42±0.46) kPa and (2.50±0.35) kPa, respectively. ConclusionCombined portoazygons devascularization and shunt not only decreases portal pressure but preserve hepatic blood flow to some extent.
ABSTRACT
Objective To study the anatomy of pelvic autonomic nerves, to avoid autonomic nerves damage during rectal cancer surgery. MethodsAnatomical dissections were carried out on 7 adult cadavers, and clinically autonomic nerve-preserving rectal cancer resection was performed. Results The superior hypogastric plexus lies just posterior to the inferior mesenteric vessels. There were no obvious autonomic nerve trunks in the loose areolar tissue plane between the parietal fascia and the visceral fascia right posterior to the rectum. There were no obvious autonomic nerve trunks between the rectum and the seminal vesicles or the prostate. The inferior hypogastric plexus was a rhomboid shaped plaque of nervous tissue. The main components of the lateral ligament were autonomic nerves passing from the pelvic plexus to the rectum within a condensation of connective tissue. WT5”HZConclusionsThe inferior mesenteric vessels can be used a landmark intraoperatively to identify the superior hypogastric plexus. In order to preserve the inferior hypogastric plexus while dissecting the lateral of rectum, we should dissect along the medial surface of the inferior hypogastric plexus, and along its curvature.

Conclusions A combined therapy consisting of chemotherapy, surgery and hormonal therapy may improve the prognosis of ICB.
ABSTRACT
Objective This experiment was to identify the influence of recombinant human endostatin (rhES) combined with 5-FU on the growth of a xenografted gastric cancer in nude mouse. Methods After the establishment of the model, mice were divided into 4 groups (six in each) receiving respectively, for consecutive 10 days: NS, 5-FU (10 mg/kg) intraperitoneally; rhES (2 mg/kg); and 5-FU + rhES. On 15th day tumor volume was measured. The expression of VEGF, bFGF, VEGF-C, PCNA, bcl-2 and apoptosis index (AI) were examined. The tumor inhibition rate(TIR) and tumor shrinking rate(TSR) were calculated. Results Tumor volume was (43?2) mm 3 in 5 FU+rhES group,(169?45) mm 3 in 5 FU group, (95?28) mm 3 in rhES group, (1057?114) mm 3 in control group ( P
ABSTRACT
Objective To investigate the pathogenesis of portal hypertensive gastropathy(PHG). Methods Two rat models with portal hypertension(PHT) and a sham operation group were established to detect the pathological changes in histology and ultrastructure of the gastric mucosa as well as quantitative changes in histological morphology by graphic analysis computer system. Results Prominent edema, scattered red dots/ecchymosis were found in gastric mucosa in rats with PHT. Light and scan electron microscopy showed swelling or exfoliating of the epithelium cell, reduction of gastric gland number, thin of gastric mucosa, while infiltration of inflammatory cells, epithelium metaplasia were not found. The most characteristic findings were the changes of the mucosal capillaries and venules in both mucosal basal lamina and submucosa layer light microscopically, as well as the transmutation, stenosis and loose intercellular joining of the capillaries on electron microscopy. Ultrastructure observation revealed numerous pinocytes in epithelial cells as well as proliferation and hyperplasia of smooth muscle, collagenous fiber and extracellular matrix in venules. Quantitative analysis showed that the ratios of the cross sectional area and the vascular wall area between the gastric wall area(CSA/GWA & VWA/GWA) was higher in liver cirrhosis(LC) and portal vein stenosis(PVS) groups than that in sham operation(SO) group. There was a positive correlation between portal vein pressure and the ratio of the length of damaged mucosa and the length of mucosa(LDM/LM that was higher in LC group than in PVS group). Conclusions In rats with cirrhotic portal hypertension, distinct gastric microvascular morphological changes are the major etiological factor of PHG as a part of pathological changes in portal hypertension.
