0.05).Conclusions There is imbalance of Th1/Th2 cells in CHB children.Th1 cytokines are positively correlated with hepatic inflammatory activity.In the course of disease,Th2 cytokines are predominant and they have a correlation to the chronic prognosis of the illness.So we can conclude the degree and prognosis of disease by observing the change of Th1/Th2 cytokines in CHB children.

ObjectiveTo observe the manifestations of depression at different stages after cerebral concussion. Methods77 cerebral concussion patients received Hamilton Depression Rating Scale (HAMD) examination at acute stage (in the 7 days after disease) and convalescence stage (at about 30 days after disease), and then compared with 48 health adults. ResultsThe scores of anxietas somatization, cognitive handicap, retardation, dyssomnia, feeling of despair conclude the total score in the cerebral concussion patients at acute stage were all significantly higher than that of the control (P<0.05). During the convalescence stage, the scores of anxietas somatization, the change of body weight, cognitive handicap, diurnal variation, retardation, dyssomnia, feeling of despair conclude the total score were all significantly higher than that of the control (P<0.05). The scores of almost all the item of HAMD were significantly higher than that of the control at both acute stage and convalescence stage, and the scores of athymia, suicide, difficulty falling asleep, early awake, agitate, somatization, constitutional symptom, hypochondriasis, loss of weight, insight, diurnal variation, feeling of despair, anosognosia, sense of inferiority and total HAMD scores at convalescence stage were all significantly higher than that at the acute stage, but the scores of blockage, psychoanxietas, derealization, symptom of over-absorption mind, compel symptom, sense of capability decrease at the acute stage were all significantly higher than that at the convalescence stage (P<0.05).ConclusionThe manifestations of depression in the cerebral concussion patients were not completely the same, so the mental intervention should be in direction.

Objective To observe the clinical effect of abdominal Tuina and acupuncture in treating Swiss generalized anxiety disorder (GAD). Methods 80 patients of GAD caused by liver depression-qi stagnation were randomly recruited into a treatment group and a control group, 40 patients in each. The treatment group was treated with abdominal tuina & acupuncture; while the control group was treated with acupuncture exclusively. Clinical effects and hamilton anxiety scale (HAMA) score were observed in both groups before and after the treatment. Results ①There was significant difference in total efficacy between the two groups CP<0.05), and the treatment group was better than the control group. ②The HAMA score of the two groups after the treatment was lower than that before the treatment, and the difference was significant (P< 0.05). There was also significant difference of HAMA score between the two groups after the treatment (/><0.05), with the treatment group showing better results than the control group. Conclusion Abdominal tuina combined with acupuncture has sound effects in treating Swiss GAD due to liver depression-qi stagnation.

Objective To explore the anti-apoptotic mechanism of Roux-en-Y gastric bypass (RYGB) through exam?ine the postoperative change of adiponectin levels and expressions of pancreatic islets relative apoptotic protein. Methods Sixty SD rats were randomly allocated to RYGB group (n=20), type 2 diabetes mellitus group (T2DM, n=20) and normal con?trol group (NC, n=20). Rats in the NC group were fed with normal diet. In order to make type 2 diabetic rat models, the rats in the T2DM and RYGB groups were fed with high fat diet (22.19 kJ/g) combined with administration of intraperitoneal strep?tozotocin injection (STZ, 30 mg/kg) on the 13th day of high fat diet. RYGB operation were performed in RYGB group and sham-operation were performed in the T2DM and NC groups when diabetic model was contructed. Rats were weight preoper?atively and at the 7th, 14th, 21st days after operations. Fasting plasma glucose and adiponectin (ELISA) were measured preoper?atively and at 21st day postoperatively. Protein expressions of Bcl-2,Caspase 8 and Caspase 9 in pancreatic islets were ex?amined by immunohistochemistry at the 21st day postoperatively. Results Body weights do not vary significantly among three groups preoperatively. Compared to rats in the NC group, fast plasma glucose level was higher but adiponectin was low?er in rats in RYGB and T2DM groups. Body weights of rats in RYGB group decreased significantly compared to those of rats in NC and T2DM groups postoperatively. Compared to rats in T2DM group, fasting glucose level was lower while adiponectin concentrations was higher in rats in RYGB group but no differences of these parameters were seen in rats in NC group at the 21st day postoperatively. Expression of Bcl-2 in RYGB group was significantly elevated while expressions of Caspase 8 and Caspase 9 were significantly decreased compared to those in T2DM group postoperatively. Conclusion Adiponectin levelswas elevated;expressions of Bcl-2 was increased;expressions of Caspase 8, Caspase 9 were decreased upon RYGB opera?tion in T2DM model. RYGB might reduce pancreatic islets apoptosis through mitochondrial pathway.

Objective To investigate the expression and significance of Claudin 3 in adenocarcinoma of esophagus and gastric cardia.Methods We subjected pathologically confirmed 16 cases of esophageal adenocarcinoma(EAC),20 cases of esophageal squamous cell carcinoma(ESC),and 40 cases of gastric cardiac adenocarcinoma(CAC,including 15 diffuse and 25 intestinal cases).Tissue samples were collected with aid of gastroscope.Fifteen samples of normal esophageal mucosa and 15 samples of normal cardiac mucosa served as control.RT-PCR and Western blotting were used respectively to detect the mRNA and protein expression of Claudin 3 in these tissue samples.Results The mRNA and protein expressions of Claudin 3 were increased in EAC and intestinal CA compared with those in normal tissues,ESC and diffuse CAC.There was no significant difference of the expression of Claudin 3 between normal group and ESC and diffuse CAC group.Conclusion Claudin 3 might be related to the development of EAC and intestinal CAC,and expected to be the tumor maker and therapeutic target of this kind of carcinoma.

Objective To explore the significance and important measure of integrative treatment of multiple trauma patients with severe craniocerebral injury in emergency center. Methods One hundred and forty-eight multiple trauma patients with severe craniocerebral injury in emergency center from November 2002 to February 2006 were analysed retrospectively. Result In total 148 cases, 72 were cured and 26 dead, 7 were in status of plant man, 17 experienced severe deformity, and 26 did mild deformity. Conclusion Multiple trauma patients with severe craniocerebral injury usually experience a serious situation and rapid development. Therefore emergency doctors are required for organizing salvage of such patients, at the same time treatment and diagnosis are implemented. Firstly the most important key to successful salvage is appropriate disposal of fatal injury and early elimination of shock. Proper surgical choice, especially at the first time, inspection and protection of visceral functions, and attention to nutritional support are other vital methods to gain more successful salvage. ICU is also emphasized for its essentiality.

The intra day RSD was less than 7.70% and the inter - day RSD was less than 6.69% .CONCLUSION: This method is simple,pratical and accurate.It could be applied to pharmacokinetic study of hydroxyeamptothecin.

Sucking mice, 2～3 day after birth, were intraperiton eally inoculated with 0.05mL F1M10 of Chen Strain Hantaan virus. At diff erent t ime point after inoculation, the brains were taken, routinely fixed and embedded in paraffin for preparing 5 μm serial sections. Traditional and confocal immun ochemical detection of viral antigens and heat shock protein 70 were performed t o exp lore the cerebral stress response after viral infection. The results showed that HSP70 immunoreactivities could be stably detected in the viral antigen positive neurons, but not in the viral antigen negative or uninfected control tissues. B y confocal microscopic examination, the HSP70 and viral antigens were colocolize d in the neuronal cytoplasm. Our result, comparable to our previous findings in human tissues and culture cells, indicated that Hantavirus infection can induce the expression of HSP70 in the infected cells, and HSP70 expression might be n ecessary but not sufficient to keep the cell survival.
