ObjectiveTo identify the relevant factors of expansion of contusive cerebral hemorrhage following unilateral decompressive craniectomy in patients with severe craniocerebral injury and discuss their relation with prognosis.MethodsA total of 161 consecutive patients with craniocerebral injury undergoing unilateral decompressive craniectomy were prospectively studied.Their initial cranial CT data (data after injury,data before operation,and data after first operation) were recorded.Mortality or Glasgow Outcome Scale (GOS) at 6 months after injury was used as the criteria for evaluation of prognosis.ResultsThe volume of increased contusive cerebral hemorrhage among the patients after craniectomy was (18.66 ± 22.69) ml.The Rotterdam score of their initial cranial CT after injury was significantly associated with the occurrence or not of expanded contusive cerebral hemorrhage following decompressive craniectomy and the expanded hematoma volume.The expanded volume of contusive cerebral hemorrhage ( ＞ 20 ml) after craniectomy showed significant relevance to mortality and poor prognosis six months later.The magnitude of external cerebral herniation ( ECH ) on the initial post-operative CT was associated with the prognosis. ConclusionsThe severity of patients with craniocerebral injury manifested by the initial cranial CT may predict the risk of expansion of contusive cerebral hemorrhage following decompressive craniectomy.The expansion volume of contusive cerebral hemorrhage and ECH are correlated with mortality and poor prognosis.

The changes of immunoreactive TRH (TRH-ir) in cerebrospinal fluid (CSF) and plasma before and after acute traumatic head injury were determined with radioimmunoassay (RIA) on a feline model of acute experimental head trauma. The results showed that the concentrations of TRH-ir in experimental animals pre- and 2, 4, and 6h post-injury were 119.48?51.77, 460.71 ?178.72, 377.27? 139.33, and 280.17?110.46pmol/L in CSF, and 122.58?28.87,1158.89?163.18, 909.69?160.55, and 545.38?132.80pmol/L in plasma, respectively, while those in control animals measured at the corresponding time were 112.22?53.42, 105.36?49.64, 100.63?52.89, and 104.52?52.42pmol/L in CSF, and 113.57 ?25.79, 107.32?26.60, 119.84?31.53, and 117.21?28.95pmol/L in plasma, respectively. The contents of TRH-ir in CSF and plasma in the experimental group after traumatic head injury were significantly higher than those, in the control group (P

The fetal spleen cells were transplanted following the injection of S180 carcinosarcoma into the muscle,abdominal cavity,peripheral veins and portal vein in mice.The size inhibitory rate of the transplanted tumor and natural killer activity were evaluated 30 and 60 days after the injection.It was found that the growth of transplanted tumor was dramatically inhibited and natural killer activity was increased 30 days after the transplantation.But 60 days after the transplantation only portal venous transplanted tumor showed a satisfactory function of inhibiting tumor growth and natural killer activity maintained at a high level.These results indicated that portal vein was the best approach for the spleen cell transplantation

To improve the AIDS's knowledge level and intervention ability of peer lecturers in college, from the accumulation idea and activity type of experience value on Moso Teach, the author carried out systematic resource construction around the course design principles and objectives, at the same time one quantitative scoring system including learning degree and sharing degree was constructed. Through voluntary enrollment and selection among the students, the first group of peer lecturer training on AIDS prevention were set up, and 28 students were collected to experience the "mixed" application of the course. After the evaluation, it was found that there were positive functions in promoting the ability of AIDS prevention in the peer lecturer training course based on experience value of Moso Teach as the driving force and quantification. According to the problems exposed in the construction, the author put forward improvement strategies from the aspects of scoring system, off-line activities and resource optimization.

Objective To explore the surgical treatment for acute ulceration of gastric carcinoma.Methods The clinical data of 68 patients with ulceration of gastric carcinoma were analyzed retrospectively.All the cases,60 male patients and 8 females with average age of 58 years,were admitted from Jan.1990 to Jan.2007,and divided into three groups randomly,i.e.repair gastrectomy group(control,n=27),partial gastrectomy group(n=21) and radical cure group(n=20).Of the 68 patients,30 cases were diagnosed as ulceration of gastric carcinoma before surgical operation,25 cases were diagnosed as suspected ulceration of gastric carcinoma and 13 cases were misdiagnosed as gastric ulcer.All the cases were undergone operation.The ulcerations located at the superior part(6 cases),middle part(12 cases) or inferior part(50 cases) of stomach.38 cases were on Borrmann Ⅱ,and the other 30 cases were on Borrmann Ⅲ.The postoperative survival time of the patients in partial and radical gastrectomy groups was compared with that of the patients in repair group.Results Twenty-seven patients underwent repair of ulceration;21 patients received partial gastrectomy and 20 received radical gastrectomy(R2 distal subtotal gastrectomy 8 cases,R3 distal subtotal gastrectomy 12 cases).Postoperative complication occurred in 7.4% of the total cases and the mortality was 5.9%.One-,3-and 5-year survival rates were 3.7%,0 and 0 in repair gastrectomy group;52.4%,23.8% and 0 in partial gastrectomy group;and 75.0%,55.0% and 10% in radical cure group.Their Survival time were 5.93?4.95 months in repair gastrectomy groups,28.33?16.44 months in partial gastrectomy groups and 35.25?20.36 months in radical cure groups,respectively(P

Objective:To investigate the priorities of each factor influencing the casualties in refugees living in border areas, so as to provide evidence for casualty forecasting in the refugees. Methods: We summarized the factors affecting the refugee casualty in the border area through searching and reviewing the related literatures. The identified factors were classified into 3 levels and the quantitative index system was established by using Delphi method, i.e. expert consulting method. The names and the meanings of each index were revised according to experts’ suggestions after 3 rounds of consulting. The weights of each index were determined by analytic hierarchy process (AHP) and comparing-reordering method. Results: A 3-level quantitative system was successfully constructed, which consisted of 4 first level indices (including natural factors, social factors, medical factors, and war factors), 12 second level indices, and 37 third level indices; the weights of all indices were determined. Conclusion: The result of our study can be used in predicting refugee casualty and provide a reference for the medical service of refugees living in the border areas.

Objective:To observe expression and diversity of glycogen synthase (GSK)-3 and ribosome S6 protein kinase (P70S6K) in skeletal muscle of insulin resistance (IR) rat induced by high fat food and to approach the effect and significance of GSK-3 and P70S6K in IR occurrence.Methods:Forty Wistar rats aged four-week were randomly divided into normal control, high-glucose, high-fat and high-fat high-glucose groups. 8 weeks after feeding, insulin sensitivity of the rats was evaluated by hyperinsulinism euglycaemic clamps technique (ring clamp experiment), GSK-3 and P70S6K in rat skeletal muscle were measured by Western blot and epididymis fat pad weight, blood glucose, insulin, triglyceride (TG), cholesterin (TC), free fatty acids (FFAs) and hsCRP levels were also determined.Results:IR was induced, body weight (P

Objective:To compare the clinical effects of different reconstructive alimentary canal for total gastrectomy.Methods: The patients were divided into P loop/Roux-en-Y and Distal antiperistaltic jejunal reservoir group.The nutritional status of these two groups was investigated.Results:The differences of body weight,hemoglobin,total albumin and albumin afer operation one year in P loop group were(52.5?3.8)kg,(98.0?6)g/L,(52.0?2)g/L,(28.0?3g)/L;meanwhile those in Distal group were(59.2?4.8)kg,(121.0?5)g/L,(62.0?4)g/L,(35.4?2)g/L.These differences between two groups were significant(P

Objective To evaluate the effciency of different embolic agents inducing the changes of the liver morphology and function in the selective portal vein embolization (PVE).Methods Forty five Spraque-Dawley rats were used in this experiment.Five were served as a control group and forty were randomly divided into 4 groups of 10 rats each.Right PVE was performed in each group by one of four different embolic agents respectively.Five rats from each group were sacrificed and dissected to inspect the morphological changes on 14th and 21st day after the procedure.The results of different groups were analyzed according to the weight ratios of the right lobe to the whole liver and the whole liver to the body,and the results were compared to each other and those of the control group using statistical Student“ t ”test. Results After the procedure,the embolized lobe was turned gray immediately with no significant differences between groups.Both on the 14th and 21st day after the procedure,the right lobe of the liver from the rats of group 1,2,3 were atrophied apparently with lots of spotty yellow scars in different sizes.There was no significant change of the embolized right lobe from group 4.By statistical analysis,the embolization using Lipiodol-ethanol 2∶1 mixture in group 2 resulted in better atrophy than group 1 ( P 0.05) and more than the gelfoam pieces ( P

0.05). The 1,3 and 5-year regional control and survival rates in both groups were concordant, demonstrating that the prognosis of these two groups was similar. The 5-year survival rate in pre-operative radiotherapy group was 37%. The results of retrospective analysis by Log-rank and Cox proportional regression methods demonstrated that whether the tumor resected or not were the major factors affecting pre-operative radiotherapy effect.
