Objective:To study the mechanism of apoptosis in hippocampus of the rats with disorder of cortical developments.Methods:The Rats with disorder of cortical developments were established by carmustine(BUCN).AT P0,P15,P30,P45,P60,the number of apoptosis cell and expression of Bax and Bcl-2 in hippocampus were detected by TUNEL,immunohistochemistry method and RT-PCR;then the detected outcomes were analyzed by computer micrograph analysis system in control group and model group.Results:At P15,P30,P45,P60,the numbers of apoptosis,Bax,Bcl-2 masculine cell and bcl-2 MRNA,bax MRNA in hippocampus in the model group were more than those in the control group.The ratio of Bax/Bcl-2 in model group was significantly higher than those in the control group(P

From Jeunary 1986 to June 1991 107 cases of carcinoma of stomach were found by gastroscopy, in which 100cases were proved pathologically by biopsy (93.5%).The biopsy of other 7 cases was negative and the diagnosis was confirmed lately by operation.gastroscopy and pathological characteristics and their clinical significane were discussed (103 cases of carcinoma of stomach cases of early stage carcinoma ventriculi case of pinpoint carcinoma).The authors suggested that ulcer, erosion, nodule and stiff surface on the depressed mucosa at the antrum be examined carefully by means of gastroscopy and biopsy be done in order to discover early stage carcinoma ventriculi and make a correct diagnosis.Being aware of these features in not only beneficial to the reasonable clinical treatmet but also helpful to the diagnosis of carcinoma of stomach.

Pharmacodynamic (PD) studies play an important role in research and development of new traditonal Chinese medicines (TCMs). Phamacologic and toxicologic studies that aim to research drug ability can provide supporting data for the clinical trials and reduce the risk of clinical trials. In recent years, PD studies in TCMs are developing and progressing, but there are still some problems affecting the value of PD studies in the development of new TCMs. The value of PD studies depends on scientific and rational study design. This article summaries some defects in PD study design of new TCMs that are common in the application data, including defects in study type, testing targets, dosing, duration of administration, control group, testing time. This article also discusses some points of concern and specific requirements for PD study design of new TCMs.

Three-dimensional (3D) reconstruction of medical images constructs the 3D models of organs using 2D medical image serials, which provide intuitionistic visual information for medical workers. However, most people concern about the CT images reconstruction, only few people focus on the reconstruction of Ultrasound images. In this thesis, it introduces Insight Segmentation and Registration Toolkit (ITK) and The Visualization Toolkit (VTK) firstly. Then it presents the process of Ultrasound image serials using ITK and VTK. At last, it presents the outcome of the experiment. The results show that the reconstruction of Ultrasound images can also get good effect by using ITK and VTK.

Objective To investigate the efficacy of laparoscopic transcystic duct exploration for cholecystolithiasis complicated with stones in the non-dilated common bile duct.Methods Before the resection of the cyst,the cystic duct was cut under a laparoscope,and then a C tube was inserted for cholangiography.Stones in the common bile duct were removed under the guidance of C-arm X-ray.Then,C-tube drainage was carried out after removal of the calculi.Results The stones were completely removed in all of the 36 cases with a mean operation time of 125.4 minutes(90-150 minutes).The C-tube was withdrawn in 3 or 4 days after the operation.The mean postoperative time of this series was 4 to 7 days.The patients were followed up for 3 months,during which no patients had biliary leakage,residual stones,or stenosis or dilation of the common bile duct.Conclusions Laparoscopic transcystic duct exploration is minimally invasive,safe,and effective for cholecystolithiasis complicated with stones in the non-dilated common bile duct.

Since the first launching of heart lung bypass machine in animal model in 1937,cardiopulmonary bypass(CPB) has become more and more consummate,but it still brings about many complications,including pulmonary,renal and hepatic dysfunctions.Among these complications,hepatic dysfunction plays an important role in the impairment after cardiac operations.The liver function indices such as aspartate aminotransferase,glutamate-pyruvate transaminase,bilirubin and alkaline phosphatase will step up obviously during 3 to 5 days after the operation.The physiological changes deteriorate patient's condition,and even influence the prognosis.This clinical phenomenon puzzles cardiac surgeons.All these demand us to answer the following questions: Is the cardiopulmonary bypass harm the liver? What's the mechanism? We review the different researches on hepatic injury after cardiopulmonary bypass.

OBJECTIVE:To explore the observation and nursing points of hemorrhage in intravenous thrombolysis after using alteplase. METHODS:128 patients underwent alteplase intravenous thrombolysis were selected as the research object. The occur-rence of hemorrhage in each part were observed within 48 hours after medication and nursed timely. RESULTS:128 patients re-ceived intravenous thrombolysis. 48 h later,26 patients suffered from hemorrhage complications (20.3%). Among them,there were 6 cases of nose bleeding (4.7%),8 cases of subcutaneous congestion (6.3%),6 cases of gingival bleeding (4.7%) and 6 cases of gastrointestinal bleeding(4.7%). There was no significant difference in the incidence of complications among those groups (P>0.05). The time of nose bleeding was (3.2 ± 1.3) h,the time of subcutaneous congestion (3.5 ± 1.2)h,the time of gingival bleeding(1.5±0.7)h,and the time of gastrointestinal bleeding(4.1±1.8)h. The time of gingival bleeding was earlier than that of other groups,with statistically significant difference(P<0.05). There was no statistically significant difference among other groups (P>0.05). CONCLUSIONS:In alteplase intravenous thrombolysis,nurses should closely monitor hemorrhage and complications, especially the complication of gingival bleeding. Find out the complications timely and nurse it as early as possible.

Lung transplantation is now considered one of the effective management of end stage pulmonary diseases. This review presents the recent progress of primary graft failure in lung preservation, such as low temperature, ventilation, etc. The purpose is to provide some valid methods in clinical practice.

The catabolic response to severe injury , burn, inflammatory ,acute pancreatitis and operation is characterized by whole-body protein loss, mainly reflecting increased breakdown of muscle proteins. Glucocorticoids and various proinflammatory cytokines are important regulators of muscle proteolysis in stressed patients. In recent years, three types of treatments have been used to reduce or prevent the catabolic response to injury and sepsis: ①nutritional, ②hormonal, and ③pharmacologic. This article review the catabolic response and the corresponding interruption under the stress conditions.
