Objective: To explore the law of apoptosis of lumbar spinal cord neurons in cauda equina syndrome (CES). Methods: Cauda equina of rats was compressed by a piece of silica gel stick. From day 1 to day 28, the lumbar spinal cord specimens were harvested and assessed by Nissl's staining and TUNEL staining. Results: Compression of cauda equina caused lesion and apoptosis of neurons in lumbar spinal cord, and the extent of apoptosis reached the peak on 7th day after compression. Conclusion: Apoptosis of neurons in lumbar spinal cord might be one of the reasons why patients with CES get poor prognosis.

AIM: To observe the changes in contrast sensitivity (CS) between emmetropic pilots, glasses wearing, and after laser in situ keratomileuses ( LASIK) surgery pilots, provide the basis for the physical examination standard after operation.
METHODS:The CS of 13 emmetropic pilots (26 eyes), 12 glasses wearing pilots (24 eyes) and 10 with LASIK (20 eyes) , under photopic, scotopic and scotopic with glare environments at four different spatial frequencies ( 3, 6, 12 and 18cpd ) were measured and the resluts were analyzed by statistics.
RESULTS:Under photopic environments, there was no significant difference in the low spatial frequency (3cpd) among the three groups (P>0. 05). The CS of emmetropic pilots was better than that of the myopic and with LASIK, and there was significant difference (P<0. 05). There was no significant difference in CS between myopic and with LASIK (P>0. 05). Under scotopic environments, there was no significant difference in the low spatial frequency (3cpd)among the three groups (P>0. 05). The CS of emmetropic and with LASIK pilots were better than that of the myopic, and there was significant difference ( P<0.05). There was no significant difference in CS between emmetropic and with LASIK (P>0. 05). Under scotopic with glare environments, the CS of emmetropic and myopic pilots were better than that of the with LASIK, and there was significant difference (P<0. 05). There was no significant difference in CS between myopic and with LASIK (P>0. 05).
CONCLUSION: The CS after LASIK is decreased compare with emmetropic pilot, specially under scotopic with glare environments. A perfect identification standard should be set up.

Large artery intracranial occlusive disease is a important and common vascular lesion type.It is closcly associated with the onset and recurrence of ischemic stroke; however,at present there are many inadequacies in the study of its etiology and treatment.This article mainly reviews the understanding process of the large artery intracranial occlusive disease,present research results and problems need to be solved.

Objective To observe the clinical efficacy and safety of Shuxuetong in treatment of paroxysmal atrial fibril-lation in patients with chronic pulmonary heart disease. Methods A randomized single-blinded study was performed. A to-tal of 91 patients with paroxysmal atrial fibrillation and chronic pulmonary heart disease were randomly divided into treat-ment group (n=45) and control group (n=46). The treatment group was received Shuxuetong and clopidogrel treatment for 14 days. The control group was given routine treatment plus clopidogrel 75 mg orally. The average time of cardioversion of parox-ysmal atrial fibrillation was detected within 48 hours. The cardioversion rate of paroxysmal atrial fibrillation and the total effi-ciency were detected after14 days. The serum D-Dimer was detected before and 14 days after treatment . Liver and kidney function and adverse drug reactions were also detected. Results There was no significant difference in average time of car-dioversion of paroxysmal atrial fibrillation in 48 h between two groups (h:12.62±2.32 vs 13.32±2.25,t=1.461). The cardiover-sion rates were 86.67%(39/45) and 82.22%(37/45) at 48 h and 14 d in treatment group, which were significantly higher than those of control group [69.56%(32/46) and 60.87(28/46)]. The D-Dimer at 14 d after treatment was significantly lower in treatment group [(2.05±0.34)mg/L] than before treatment[(2.61±0.27)mg/L], also than that of control group[(2.53±0.31)mg/L]. There were no abnormal liver and kidney function and no adverse reactions between two groups. Conclusion Shuxuetong can significantly prevent the recurrence of paroxysmal atrial fibrillation in patients with chronic pulmonary heart disease, and help to reduce the risk of thromboembolism. It is safe and effective.

Objective:To study the effect of articulation disorder on psychology action of cleft palate patients after operation.Methods:65 patients were asked to answer the psychology questionnaire.Results:The patients of misarticulation all have some degree of psychological disability,and unusual psychology action would affect pronunciation treatment.Conclusion:Patients with misarticulation have psychology problems in some degree,which would affect the clinic treatment of cleft palate.

Polyactin B (Pb) has been proved to have the effect of considerable tumor suppression. Recently,we used murine S_(180) Sarcoma as a model and observed the effect of Pb on the tumor—infiltrating immunocompetent cells, and also the infiltrating neutrophils and the alteration of small blood vessels within the tumor tissue. Compared with control: in Pb—treated group, there were more L_3T_4~+and Lyt_2~+ lymphocytes infiltrating in the periphery of the tumor ,and also within the tumor. In addition, the tumors had more prominant hyperemia, micro—thrombosis and neutrophil infiltration around the necrotic areas. The present findings suggest that the tumor—suppression effect of Pb might be mediated through TNF produced by immunocompetent cells.

Objective To investigate the diagnosis and treatment of Hydatidosis of post-peritoneum and bladder.Methods Nine cases were reported. Among them,one was epinephros-hydatid cyst,two renal hydated cyst,two hydatidosis of post-peritoneum in ileopelvic, and four bladder hydrated cyst. All cases had history of contacting with dog or sheep.Results All of the nine cases were cured by operation. Conclusions In percussion of the lower abdominal mass, hydrated cyst vibration, a specific sign, can usually be felt; and the mass do not disappear after urination. Besides, E-immune Test for echinococcus, B-ultrasonography, and CT are very useful diagnostic methods. Therefore, excision of the cyst still is the only effective treatment for hydatidosis.

Objective To investigate the correlation between caspase-3 and left ventricular function at different phases after ischemia-reperfusion. Methods Totally 36 wistar rats were randomly divided into Sham operation group and ischemia-reperfusion(IR)group. The rat ischemic cardiac region of IR group was taken after 1, 3, 6, 12 and 24-hour reperfusion followed to 30-minute ischemia and detected for the activity fragment of caspase-3 P20, the activity of caspase-3, myocardial apoptosis index, left ventricular function (LVF) and creatine kinase-MB (CK-MB) respectively. Results With reperfusion time prolonging, the activity fragment of caspase-3 P20 increased, the activity of caspase-3, myocardial apoptosis index, left ventricular function and CK-MB all changed. The activity fragment of caspase-3 P20 and CK-MB peaked at 6 h, and the activity of caspase-3 and myocardial apoptosis index at 12 h, and then maintained platform; LVSP and ?dp/dt_max increased while LVEDP decreased gradually with the reperfusion time prolonging. All indexes mentioned above of IR group had statistical significance as compared with that of Sham operation group(P
