To study the clinical significance of combined measurement of neuron specific enolase(NSE), carcinoembryonic antigen(CEA) and Cytokeratin19 fragment 21 1 (CYFRA 21 1 ) in the diagnosis of lung cancer. The serum levels of CEA, NSE, and CYFRA 21 1 in 75 lung cancer patients as well as in 22 benign pulmonary diseases patients were measured by radioimmunoassay. Patients with pulmonary adenocarcinoma had a highest CEA level. Small cell lung carcinoma (SCLC) patients had a highest NSE level, while patients with squamous cell carcinoma of lung had a highest CYFRA 21 1 level. The positive rate of the combination of CEA, NSE, and CYFRA 21 1 for lung cancers was 82 67%. The results suggested that the combined measurement of CEA, NSE, and CYFRA 21 1 was helpful in the diagnosis of lung cancer.

Objective To assess the outcomes of modified spiral ileal orthotopic neobladder.Methods From January 1998 to January 2008, 32 patients (all male) underwent radical cystectomy and spiral ileal orthotopic substitution for muscle invasive bladder cancer. A segment of 40 to 45 cm ileal loop was isolated, detubularized, and reconfigured in spiral shape to form a pouch. Bilateral ureters were reimplanted by inserting the 1 cm distal segment into the pouch to form a Split-Cuff nipple.The bottom of the pouch was opened and anastomosed with the urethra (4 stitches). Results There were no perioperative deaths. The mean operative time was 281.2±48.7 min. Blood loss was 545.4±181.9 ml. Twenty cases required a blood transfusion, the mean volume of intraoprative blood transfusion was 430.8±235.9 ml. The average hospital stays were 26.8±9. 7 days. Rate of daytime continence was 93. 7% (30/32) while nighttime continence was 81.3% (26/32). Urodynamic studies were carried out in 23 cases 6 months after surgery. Neobladder capacity at first desire to urinate was 315.0± 33.4 ml(270-420 ml). The maximum neobladder capacity was 490. 3±39.7 ml(350-600 ml).The maximum flow rate (Qmax) was 16.5 ± 5.9 ml/s. Full resting pressure was 22. 5 ± 11.8 cm H2O. Peak voiding pressure was 78.3 ± 14.7 cm H2O. After mean 58. 4 months' follow up (range 22 to 132), 4 cases died of metastasis of bladder cancer. Conclusion Modified spiral ileal orthotopic neobladder is a reasonable option for treating invasive bladder cancer.

Objective To investigate the characteristic of the cisplatin-induced damage of hair cells in cochlear organotypic cultures. Methods Three to four-day-old (P3~4) C57 mice were used for this study. The cochlear basilar membrane was cultured for 6~8 hours and then treated with different doses of cisplatin(0?mol/L, 10?mol/L, 50?mol/L, 100?mol/L, 400?mol/L, 1000?mol/L,7 cochlears for 0-100?mol/L group, 6 cochlears for the rest dosage, control group used the dose of 0?mol/L)for 48 hours.TRITC-phalloidin and DAPI were used for stain. The entire cochlear hair cells were observed and counted under Nicon fluorescent microscope. Data was analyzed by LS for hair cells loss graph and SAS 8.0 for linear regression analysis. Results Hair cells loss had rarely been seen in the control group of cochlear tissue under the culture condition. How ever, in cisplatin treated groups, the hair cells loss increased from 14.5% to 78.4% with the concentration of cisplatin increased in the range of 10?mol/L-100?mol/L, while decreased from 48.8% down to 8.77% with the dose getting further higher to 400?mol/L and 1000?mol/L. Apoptosis was confirmed by the DAPI stain in the hair cells loss area. The hair cell loss shows no difference from the apex to the basal turn of the basilar membrane. Conclusion Cisplatin-induced hair cell death shows characteristic damage that it is dose-dependent in a certain range of dosage, and it decreases when the cisplatin dose higher than the one caus maximal damage under the condition of cochlear organotypic cutures. Apoptosis happens evenly in inner and outer hair cells in all turns of basilar membrane.

BACKGROUND: Early clinical researches suggest that mediodespidine capsule can decrease blood pressure of patients with primary hypertension on the basis of yanggan qinggan pinggan technique.OBJECTIVE: To observe the effect of mediodespidine capsule on primary hypertension and angiotensin Ⅱ (Ang- Ⅱ ) of patients in the types of yin deficiency, yang excess and liver fire.DESIGN: Randomized controlled case observation.SETTING: Department of Cardiology, First Affiliated Hospital, Hunan University of Traditional Chinese Medicine.PARTICIPANTS: Patients were selected from the Inpatient Department and Out-patients Clinic of the First Affiliated Hospital of Hunan University of Traditional Chinese Medicine between April 1999 and April 2000. Inclusion criteria: Patients, who were diagnosed with the criteria of primary hypertension, who belonged to the types of yin deficiency, yang excess and liver fire, who could endure this test, who were coincidence with the criteria of mental-stress test, were all consent. Exclusion criteria: Patients who had severe congestive heart failure, atrophic arthritis and unable tolerance were excluded. There were 60 cases in total, including 29 males and 31females. All patients were divided into mediodespidine group and verapamil group with 30 in each group on the basis of randomly digital table.METHODS: Patients who had positive results of awaken mental-stress test were involved in this study. Cases in mediodespidine group were treated with mediodespidine capsule, which was made of tall gastrodia tuber, spine date seed and fourstamen stephania root at the dosage of 0.43 g/pill and were provided by the First Affiliated Hospital of Hunan University of Traditional Chinese Medicine (wei yao ji zi: 05-047, batch number: 990503), five pills each for 3 times a day. Cases in verapamil group were treatedwith verapamil (40 mg/pill, Shanghai Huanghe Liya PharmaceuticalCompany Limited,batch number: 980301B) 80 mg each for 3 times a day. The course in both groups was 4 weeks. ① Effect of blood pressure: Average value of blood pressure tested for 3 successive days were regarded as the blood pressure before treatment, and average value of blood pressure tested for 3 times after treatment was regarded as the blood pressure after treatment. ② Effect of symptom:Scores were recorded as four levels according to main symptoms, such as vertigo, headache, pain and weakness of waist and knees, before and after treatment. ③ Values of Ang- Ⅱ were measured with radioimmunoassay before and after cold pressor test. Effect on Ang- Ⅱ was evaluated with effect of decompression, effect of clinical symptom and criteria of clinical effect.MAIN OUTCOME MEARUSES: Clinical symptoms, values of blood pressure, heart rate and Ang- Ⅱ before and after cold pressor test.RESULTS: A total of 60 patients with primary hypertension were involved into the final analysis.① Totally effective rate of clinical symptoms of patients in mediodespidine group was higher than that of patients in verapamil group, but the effect of decompression was not significant between the two groups (P > 0.05). ② There was remarkably significant difference of heart rate in both groups before and after treatment (P < 0.01), especially the decrease in verapamil group was great, and there was significant difference (P < 0.05). ③ Values of systolic pressure and diastolic pressure were decreased in both groups after cold pressor test (P < 0.01), but there was no significant difference between the two groups (P > 0.05). ④ There was no significant difference in clinical effect between the twogroups (P > 0.05).⑤ After treatment, concentration of Ang- Ⅱ at basic level in both groups was decreased, and there was significant difference between them (P < 0.01);concentration of Aug-Ⅱ was decreased in both groups after cold pressor test as compared with that before treatment, but there was no significant difference between them (P > 0.05).CONCLUSION: Mediodespidine capsule can decrease blood pressure stably, and the effect is stronger than that of verapamil at the aspect of decompression and improving symptoms. Blood pressure of patients with primary hypertension in the types of yin deficiency and yang excess or liver fire can be decreased by decreasing the level of plasma Ang-Ⅱ to a certain degree.
