15 cases of diaphragmatic traumatic hernia were reported. The majority of patients were young people. The location of lesion was on the left in 14 cases and one on the right. There were 8 close and 7 open cases. The size of the rupture on the diaphragm was from 3 to 15cm. The importance of earlier diagnosis and treatment were also discussed.

Percutaneous transluminal coronary angioplasty (PTCA) is one of the effective interventions for treating atheroclerotic corona ry heart disease. However, myocardial ischemia caused by balloon dilation during the operation has raised great concern. As a result, administration of drugs an d mechanical measures have been employed perioperatively to protect the cardiac muscle so as to prevent or reduce the myocardial ischemia and ensure the safety of the operation. This paper reviews the significance and methodology of pharmac ological myocardial protection during PTCA.

Golgi protein-73 (GP73) is a type-lⅡ Golgi glycoprotein localized on the membrane of the Golgi complex.Recently,a growing number of studies have demonstrated that the expression of GP73 is closely correlated with primary hepatocarcinoma (PHC).GP73 has a higher sensitivity and specificity than alpha-fetoprotein (AFP) and it may be a novel serum marker for the detection of PHC,especially for early PHC.This article reviews the relationship between GP73 and PHC.

OBJECTIVE: To explore the applications of imaging examination on rib fracture sites in forensic identification. METHODS: Features including the sites, numbers of the processed imaging examination and the first radiological technology at diagnosis in 56 cases of rib fractures from 163 injuries were retrospectively analyzed. RESULTS: The detection rate of the rib fractures within 14 days was 65.6%. The initial detection rate of anterior rib fracture proceeded by X-ray was 76.2%, then 90.5% detected at a second time X-ray, while the detection rate of CT was 66.7% and 80.0%, respectively. The initial detec- tion rate of rib fracture in axillary section proceeded by X-ray was 27.6%, then 58.6% detected at a second time X-ray, while the detection rate of CT was 54.3% and 80.4%, respectively. The initial detection rate of posterior rib fracture proceeded by X-ray was 63.6%, then 81.8% detected at a second time X-ray, while the detection rate of CT was 50.0% and 70.0%, respectively. CONCLUSION It is important to pay attention to the use of combined imaging examinations and the follow-up results. In the cases of suspicious for rib fracture in axillary section, CT examination is suggested in such false X-ray negative cases.

OBJECTIVETo explore the possible neurophysiologic mechanisms of propofol and N-methyl-D- aspartate (NMDA) receptor antagonist against learning-memory impairment of depressed rats without olfactory bulbs.

METHODSModels of depressed rats without olfactory bulbs were established. For the factorial design in analysis of variance, two intervention factors were included: electroconvulsive shock groups (with and without a course of electroconvulsive shock) and drug intervention groups [intraperotoneal (ip) injection of saline, NMDA receptor antagonist MK-801 and propofol. A total of 60 adult depressed rats without olfactory bulbs were randomly divided into 6 experimental groups (n=10 per group): ip injection of 5 ml saline; ip injection of 5 ml of 10 mg/kg MK-801; ip injection of 5 ml of 10 mg/kg MK-801 and a course of electroconvulsive shock; ip injection of 5 ml of 200 mg/kg propofol; ip injection of 5 ml of 200 mg/kg propofol and a course of electroconvulsive shock; and ip injection of 5 ml saline and a course of electroconvulsive shock. The learning-memory abilities of the rats was evaluated by the Morris water maze test. The content of glutamic acid in the hippocampus was detected by high-performance liquid chromatography. The expressions of p-AT8Ser202 in the hippocampus were determined by Western blot analysis.

RESULTSPropofol, MK-801 or electroconvulsive shock alone induced learning-memory impairment in depressed rats, as proven by extended evasive latency time and shortened space probe time. Glutamic acid content in the hippocampus of depressed rats was significantly up-regulated by electroconvulsive shock and down-regulated by propofol, but MK-801 had no significant effect on glutamic acid content. Levels of phosphorylated Tau protein p-AT8Ser202 in the hippocampus was up-regulated by electroconvulsive shock but was reduced by propofol and MK-801 alone. Propofol prevented learning-memory impairment and reduced glutamic acid content and p-AT8Ser202 levels induced by electroconvulsive shock.

CONCLUSIONElectroconvulsive shock might reduce learning-memory impairment caused by protein Tau hyperphosphorylation in depressed rats by down-regulating glutamate content.

Objective To explore the association of expression between the longevity gene SIRT1 and the forkhead transcription factor FOXO1 in the beta cell of islet in rat,and provide the basic prevention and cure rationale for the type 2 diabetes mellitus.Methods Eleven male SD rats of 18 months old were randomized into two groups:6 in calorie restriction(CR)group and 5 in the control group.After 6 months' breeding,the caudal end of islet was collected.The expression and location of SIRT1,FOXO1 and insulin were detected by immunohistochemistry;sections of pancreas were stained for senescence-associated ?-galactosidase(SA-?-Gal)to identify cell senescence of pancreatic islets.Results SIRT1 and FOXO1 were expressed in both the kytoplasm and nucleus,while insulin and ?-Gal were located in the kytoplasm.Compared with the control group rats,there was higher SIRT1 expression(P0.05)expression was detected in the beta cells of CR group rats.The lower positive rate of FOXO1 located in the nucleus the higher expression of SIRT1 in the rat beta cell of islet.Conclusion Calorie restriction could induce the high expression of SIRT1 in the rat beta cell of islet,and we think SIRT1 may delay the senescence process of rat beta cell through the repression of transcription factor FOXO1;it's beneficial to the prevention and cure for type 2 diabetes mellitus.

The Workers' Hospital of Huangmian Group in our city, which succeeded in separating from the enterprise and becoming commercially oriented through reforming the property right system, has made some worthwhile attempts at transforming the property right system of enterprise-owned hospitals. The experience accumulated includes: commercialization of enterprise-owned hospitals through reforming the property right system is a must in adapting to the system of the socialist market economy and setting up the system of modern enterprises; it is also a must in the current reform of the health system; reform of the property right system of enterprise-owned hospitals gave strong impetus to the reform of operational mechanisms of personnel matters, distribution and management within the hospitals; appropriate policies are the key to ensuring the success of the reform; and hospitals with transformed ownership ought to maintain their original functions and continue to undertake such social tasks as medical treatment, prevention of diseases, healthcare and supervision of public hygiene.

Objective:To study on the law of application of drugs in complex prescriptions of Chinese herbs for treatment of hypertension. Methods:The author read 1 102 papers about treatment of hypertension from 1980 to 2003,collected 1 191 complex prescriptions of Chinese herhs,established Access database of complex prescription of Chinese drugs for treatment of hypertension,and analyzed the law of application of drugs in complex prescription of Chinese herbs for treatment of hypertension by combination of Access, Excel with VB programming based on the database.Results:In the 1 191 complex prescriptions of Chinese herbs,394 herbs were used 11 371 times.Among them,the drugs for reinforcing deficiency,clearing heat,calming the liver to stop the wind,and activating blood stasis and removing blood stasis are main.192 pairs of drugs were used over 50 times,with 21 traditional drug pairs of Chinese medicine,and combination principles of the first 10 pairs with the highest application frequency were analyzed by TCM combination theory.And there were 30 drug groups which were used for over 50 times,and prescription composition principles of the first 10 groups with the highest application times were analyzed by TCM composition theory.Conclusion:Large- scale data process with computer is an effective method for finding the law of application of drugs in Chinese complex prescriptions for treatment of hypertension.
