To explore the stability of impact assay for determination of microorganism in indoor air, the comparisons of continued sampling times of 2-minute and 4-minute for monitoring on microorganism of indoor air were carried out with JWL- Ⅱ B multifunctiom air microorganison monitor in 11 hotels, public places of entertainment, barbar shops and beauty shops. The results showed that, under a same environmental condition, there was no significant differences between the data obtained by 2-minute monitoring and 4-minute monitoring (t=1.854, P＞0.05).It indicated that impact assay presented very good stability in detecting the microorganism of indoor air within certaindetecting duration.

Objective To analyze the mechanism of hemiparalysis children,cerebral vessels' physiological feature of children, pathological change and therapeutic efficacy after light craniocerebral trauma. Methods To analyze clinical manifestation,imageology data,therapy and therapeutic efficacy of 32 hemiparalysis children patients after light craniocerebral trauma. Results Mon-basal ganglia cerebrel infarction was discovered in all children,and cure rate of broadening blood vessel therapy was 84% in a week after trauma. Conclusion Blood vessel spasm and thrombosis happened after light craniocerebral trauma to artery of cerebral hemorrhage that erupt perpendicularly from arteria cerebri media and had incomplete tunica intima development. Nonage broadening blood vessel therapy could gain well curative effect.

Objective To understand cerebral edema and development procedure of different time windows.Methods To analyze their prognosis through image document and operation findings of 52 cerebral trauma patients which were confirmed cerebral edema by CT and operation.Results he light cerebral oedema patients have a better prognosis,10 patients died and 1 patient became a plant man in 11 malignant brain dilatation patients.Conclusion The infernal circle of high brain pressure-cerebral ischemia,cerebral anoxia-cerebral edema result in cerebral edema-brain dilatation-malignant brain dilatation after cerebral trauma which leads to unremitting aggravated pathogenefic condition.So effective means should be used to interrupt the unremitting heightening ICP.

Objective To investigate the preventive application of octreotide acetate for the prevention of complications and serum pancreatic amylase secrection after pancreatoduodenectomy(PD).Methods Fiftysix cases who underwent PD in our hospital were randomized into the observational group (n =28) and the control group (n =28).The control group received routine preoperative treatment including fasting,gastrointestinal decompression,nutritional support,maintenance of water,electrolyte balance and the use of antibiotics,postoperative routine parenteral nutrition and antibiotic therapy.In addition to the conventional treatment,the observational group received prophylactic application of octreotide acetate by subcutaneous injection of 0.1 mg each time,3 times a day,and 7 days for a cycle of treatment.Blood biochemical index and postoperative complications in the two groups were monitored.Results The serum amylase levels in the observational group and the control group were (304.63 ±62.21) U/L and (445.52 ±64.52) U/L respectively at the tenth day after treatment.The two groups are significantly different in the serum amylase level (t =2.243,P ＜ 0.05).The pancreatic juice,gastric juice and bile drainage of patients in the observational group and the control group were (46.83 ± 31.42) ml,(189.92 ± 59.64) ml,(178.94 ± 45.18) ml,and (69.84 ± 34.30)ml,(237.08 ±71.27) ml,(356.11 ±64.23) ml respectively.The observational group had significantly reduced digestive fluid drainage volume compared with the control group (t =3.219,2.276,4.618 respectively,P ＜0.05).Complications occurred in 3 patients of the observational group (including 1 case of pancreatic fistula,1 case of hemorrhage,and 1 case of gastric emptying delay),with an incidence of 10.71％ (3/28).Complications occurred in 12 cases of the control group (including 3 cases of pancreatic fistula,2 cases of hemorrhage,3 cases of bile leakage,2 cases of delayed gastric emptying,2 cases of peritoneal infection),with an incidence of 42.86％ (12/28).There was significant difference between two groups in the incidence of complications (x2 =4.293,P ＜ 0.05).Conclusion Prophylactic application of somatostatin in PD restrains the secretion of digestive juice,and plays a preventive role for postoperative complications.The routine prophylactic application of octreotide in PD is necessary.

Objective To discuss the correlation between the expressions of high mobility group protein box 1(HMGB1),VEGF-C/D and lymph node metastasis in colon cancer.Methods Forty-five colon cancer samples were stained by immunohistochemical method for VEGF-C/D,HMGB1.The correlations of VEGF-C/D,HMGB1 expressions and lymph node metastasis were analyzed statistically.Results Positive HMGB1 expression was in 33 specimens,lymph node metastasis was in 27 specimens with 23 specimens of positive HMGB1 and non-lymph node metastasis was in 18 specimens with 10 specimens of positive HMGB1.Positive VEGF-C expression was in 27 specimens with 20 in lymph node metastasis.The expression of HMGB1 was consistent with VEGF-C expression,and HMGB1 and VEGF-C expressions were closely correlated with lymph node metastasis,but not with age,sex,cellular differentiation.Conclusion HMGB1 and VEGF-C expression may become predictor to the prognosis of colon cancer patients.

Objective: To establish a model of rat osteosarcoma in nude mice and to study its biological characteristics.Methods: Intact tumor pieces were inoculated into the right tibia of nude mice.The nude mice were killed at different time and the growth of tumor and metastasis were observed.Result: The tumor growth rate was 100%.From the first week to the second week after implantation it grew into outer tissue from tibia,and widely invaded Soft tissue on the third week.Pulmonary metastasis took place from the fourth week to the fifth week,and the nude mice died of cachexia and respiratory failure resulting from the widely whole pulmonary metastasis on the sixth week or so.Conclusion: The tumor growth rate is high.The model simulates the clinical process of human osteosarcoma,and could be a satisfactory model for studying osteosarcoma.

Objective:To develop an HPLC method for the assay of the content of triptolide in triptolide gel. Methods:The content of triptolide was measured by HPLC on Diamonsil C18 column(250mm?4.6mm i.d,5?m)using methanol-water(46∶54,v/v)as mobile phase,at a flow rate of 1.0ml/min. The UV detection was set at 220nm. Results:The calibration curve was proved to be linear in the range of 10.24~51.20?g/ml with a regression coeficient of 0.999 7. The average recovery of the method was 98.3%;RSD was 0.23%(n=5). Conclusion:This method is found to be rapid and accurate for the measurement of triptolide in triptolide gel.

Functional gastrointestinal diseases(FGIDs) mainly include functional dyspepsia (FD),irritable bowel syndrome (IBS),functional constipation (FC) and functional abdominal pain syndrome (FAPS).In gastroenterology outpatient,42%～61% FGIDs patients have psychological factors,mostly depression and anxiety.The personality of these patients are almost introvert.Negative life events can be an incentive to lead to depression and anxiety which can aggravate the functional gastrointestinal symptoms.Clinical manifestations include long-term abdominal discomfort,abdominal pain (some with no fixed position),abdominal distension,anorexia,change in bowel habits,retrosternal and upper abdominal burning pain or overlapping symptoms.Some have obvious emotional performance.Dyspepsia symptom score of FD patients with mental disorders are higher than those who have no emotional performance and the gastric emptying decrease greatly than the latter.FGIDs treated by systemic therapy but with no improvement in symptoms may have somatization,compulsion,interpersonal tension,depression,anxiety and other psychological disorders.So psychological evaluation should be carried out to make early recognition for refractory functional gastrointestinal disorders.

TCM has dominance and characteristics in treating chronic nephritis, such as protecting the function of kidney and defering the kidney crocking up. Professor LI Ji-ren, a famous herbalist and the gainer of the special allowance of the State Council, has worked on clinic for 60 years.
