Objective To investigate the intervention ways of endoscopes in the treatment of esophagus stenosis due to carcinoma of esophagus and improvement of quality. Method 11 cases of advanced carcinoma of esophagus were included in this study. Operation and chemical therapy were unavailable for these patients. Memory trestle with membrane and made of alloy of Nickel－ titanium was inserted under intervention of endoscope. Trestle was posed in stenosis part of esophagus under direction of X－ ray. Trestle could be dilated 3－ 7 days after operation due to its reaction characteristics to temperature. So, redilated therapy was unnecessary. Trestle could reconstruct swallowing tract and made feeding through mouth become available during limited survival time.Results All trestles were successfully inserted.Half－ fluid feeding was available after operation. Obstruction was removed in all patients(100％ ).Conclusion Method described in this study was safe and effective .Effective swallowing tracts were reconstructed in all patients after trestle was planted and quality of life and survival time were both improved.

AIM: To investigate the protective effects of total of flavone C (TFC) on acute cerebral ischemia in mice and focal cerebral ischemia in rats. METHODS: The occlusion of bilateral common carotid arteries with vagus nerves in mice was used for make the acute cerebral ischemia models. The survival time and the death rate were observed. The permanent occlusion of the proximal of the right middle cerebral artery (MCA) was used for make the focal cerebral ischemia models. The extent of neurological deficits was observed, and the infarct area was measured by NBT staining technique. The activity of LDH and the content of MDA and NO in the ischemic cerebral cortex were determined. RESULTS: TFC of 80 and 40 mg?kg -1 prolonged the survival time and decreased the death rate of mice with acute cerebral ischemia injury. TFC of 60, 30, and 15 mg?kg -1 ameliorated neurologic deficits score and the infarct size of rats with MCAO. CONCLUSION: TFC provides significant protective effects against cerebral ischemia injury.

Objective To find out the correlation of C -reactive protein (CRP)and acute cerebral infarc-tion,and to provide research data for acute cerebral infarction.Methods 43 cases with acute cerebral infarction were set as the observation group,and 40 healthy people were set as the control group.The CRP level of the observation group and the control group,and CRP level of different infarction volume and neurological function defect degree were compared.The influence factors of CRP level were analyzed with single factor analysis and Logistic regression.Results The CRP level of the observation group was (14.19 ±2.60)mg/L,which was significantly higher than that of the control group (t =7.453,P <0.05).With the increase of infarction volume,CRP levels increased (t =3.451,8.534, 5.930,all P <0.05).With the increase of nerve function defect degree,CRP level elevated (t =3.845,9.077, 6.730,all P <0.05).CRP level and systolic blood pressure,fasting glucose,total cholesterol,fibrinogen were positively correlated (r =0.479,0.603,0.508,0.603,all P <0.05 ).Cerebral infarction,systolic blood pressure,fasting glucose,total cholesterol and fibrinogen were the influence factors of CRP level.Conclusion There is correlation between C -reactive protein and acute cerebral infarction;detecting CRP level can assist in diagnosis of cerebral infarction.It was favorable to prevent and control the occurrence and progress of acute cerebral infarction.

OBJECTIVE:To study the effects of Tibetan medicine Zuotai on the activities of cytochrome oxidase (CYP1A2) and drug metabolism enzyme N-acetyltransferase 2(NAT2)in rats. METHODS:70 SD rats were equally randomized into a normal control (normal saline) group,the groups of single administration of low,middle and high-dose (1.2,3.8 and 12 mg/kg) Zuotai and the groups of multiple administrations thereof(once daily for 12 consecutive days). The rats were given drugs ig. caffeine(25 mg/kg)was given ig to the rats in the normal control group and the groups of single administration on the 2nd day,and to those in the groups of multiple administrations on the 13th day. 5 h later,their urine was collected and added with vitamin C based on 10 mg/ml. High performance liquid chromatography (HPLC) was adopted to determine the cafeine metabolites contents of 5-acetami-do-6-formamido-3-methyl-uric acid(AFMU),1-methylxanthine(1X),1-methyl-uric acid(1U)and 1,7-dimethyl uric acid(17U) in rats’urine,and the activities of CYP1A2 and NAT2 were reflected through (AFMU+1X+1U)/17U and AFMU/(AFMU+1X+1U). RESULTS:Compared with normal control group,the(AFMU+1X+1U)/17U and AFMU/(AFMU+1X+1U)in rats were de-creased,namely the activities of CYP1A2 and NAT2 were lower in the groups of single administration of middle-dose Zuotai and multiple administrations of middle and high-dose Zuotai than in the normal control group. There was statistical difference (P<0.05). CONCLUSIONS:Zuotai can obviously inhibit the activities of CYP1A2 and NAT2 in rats.

Objective To explore the clinical significance of preserving the intercostobrachial nerve (ICBN) in the radical resection of breast cancer. Method All of 140 cases of breast cancer with Ⅰ - Ⅲ a stage operable eligible,were randomly divided into the experimental group with 79 cases (7 cases were rejected, 1 case was lost) that patients received radical resection of breast cancer with preservation of ICBN,and the control group with 61 cases (2 cases were lost) that patients received routine radical resection of breast cancer based on the time of admission. Analyzed postoperative local recurrence and compared to sensory dysfunction of the two groups. Results There was no significant difference between the two groups of patients in the rate of postoperative local recurrence [0-4.2% ( 3/71 ) vs. 0-3.4% (2/59)] ( P ＞ 0.05 ). The local sensory disturbance of the experimental group [2.8% (2/71 )-11.3% (8/71)] was significantly lower than the control group [54.2%(32/59)-71.2%(42/59)], there was significant difference between the two groups (P ＜ 0.01 ). Conclusion Radical resection of breast cancer with preservation of ICBN is an ideal operation in breast cancer.
