70% . The patients were mechanically ventilated. VT was set at 10 ml? kg-1 and respiratory rate at 12 bpm. End-tidal PCO2 was maintained at 30-35 mm Hg. End-tidal PCO2, SpO2, ECG and BP were continuously monitored. The respiratory function and mechanics were measured using respiratory monitor CP-100 (BICORE) before and after pneumoperitoneum (intra-abdominal pressure reached 15 mm Hg) and 5,10,15,20,25,30,35 min after vecuronium. The respiratory parameters measured included inspiratory and expiratory VT ( VTi, VTe) , minute ventilation (VE), respiratory rate (RR), peak inspiratory and expiratory flow rate (PIFR,PEFR), PEEP, auto-PEEP, pressure-time product (PTP), inspiratory-time ratio (TI/TTOT ), rate/VT ratio, average airway pressure (PAWM), esophageal pressure (PES), peak inspiratory pressure (PIP), dynamic compliance (CDyn), airway resistance (RAw ) and work of breathing. Results There was no significant difference in the effect of different doses of vecuronium on respiratory function and mechanics including all parameters measured at all time points among the three groups. Mean airway pressure, esophageal pressure peak inspiratory pressure, airway resistance and work of breathing increased significantly but dynamic compliance decreased significantly after CO2 penumoperitoneum. Conclusion Intra-abdominal CO2 insufflation significantly attect respiratory mecnanics. me effect of pneumoperitoneum on respiratory mechanics can not be prevented or attenuated by increasing the dose of muscle relaxant.

Objective To study the relationship between tacrolimus blood level/dose and the genotype of CYP3A5 at 6th month after lung transplantation.Method Forty-six cases of lung transplant recipients who received the surgery between January 1st,2011 and January 1st,2013 served as the research subjects,and the genotypes of these patients were measured.These patients were divided into 3 groups (CYP 3A5 * 1 * 1,CYP 3A5 * 1 * 3,CYP 3A5 * 3 * 3) according to their different genotypes.The dose of tacrolimus and daily intake were detected at 6th month after surgery in each group,then the level/dose of tacrolimus was calculated.Result In all 46 recipients,5 of them were CYP 3A5 * 1 * 1 homozygous genotype,20 CYP 3A5 * 1 * 3 heterozygous genotype and 21 CYP 3A5 * 3 * 3 homozygous genotype.Under the condition of holding tacrolimus blood level between therapeutic range,there was significant difference in the dose of tacrolimus between the CYP3A5 * 1/ * 1 and * 1/* 3 versus * 3/* 3 genotypes (P<0.01),but there was no significant difference between CYP3A5 * 1/* 1 genotype and * 1/* 3 genotype.Conclusion Tacrolimus dosing in lung transplant patients is associated with CYP 3A5 gene polymorphisms.

Chinese Journal of Urology 2001;0(06):-
Objective To present the means of localizing the kidney with ectopic ureter in order to provide the reliable ground for surgical strategy. Methods Clinical manifestation study,IVU,SPECT imaging and cystoscopy were conducted.All the 58 patints are female with a mean age of 3.4 years.According to the creteria presented in reference,5 were type Ⅰ,42 type Ⅲ,1 type Ⅳ,8 type Ⅴ and 2 type Ⅵ. Results Operative finding revealed the accurate localization and diagnosis rate of IVU has been 95%(40/42) in type Ⅲ ectopic ureter,B-ultrasonograph 27%(12/53),SPECT 37%(6/16).With the combined consideration of imaging procedures and cystoscopy,the accurate localization and diagnosis rate has been 98%(57/58). Conclusions Combined use of imaging procedures and cystoscopy would improve the localization and diagnosis rate.Cystoscopy is the most reliable except in type Ⅲ ectopic ureter.

To probe the effect of reduced form coenzyme Ⅰ(NADH) in antagonizing cardiac muscle toxicity induced by doxorubicin and its underlying mechanism. Primary culture of myocardial cells of SD rat and doxorubicin injury model were established. MTT assay, laser confocal microscopy, transmission electron microscopy and biological oxygen monitor were used to observe the morphology and function of mitochondria. The results showed that the killing rate was increased in the group of doxorubicin, and that in the group of NADH/doxorubicin was greatly decreased. Doxorubicin could induce ultrastructural damage of cardiomyocyte mitochondria, manifested as swelling, disintegration, disruption of cristae and fusion. Cardiac mitochondria were protected against injuries in the group treated with NADH/doxorubicin. There was a significant difference in the fluorescence intensity of mitochondria membrane potentional and ROS between the groups treated with doxorubicin and NADH/ doxorubicin. It is suggested that NADH can significantly antagonizing cardiac muscle toxicity induced by doxorubicin and can protect mitochondrial structure and function.

Objective To introduce the Bernese periacetabular osteotomy through ilioinguinal approach for the treatment of adult acetabular dysplasia. Methods From October 1997 to April 2001, 51 patients(53 hips) with acetabular dysplasia were operated upon with Bernese periacetabular osteotomies through ilioinguinal approach. The mean age of the patients at the time of surgery was 30.6 years(range, 13-48 years). Male∶female= 1∶10. Preoperatively, the average duration of the symptoms was 3.4 years(3 months to 15 years), the range of motion(ROM) of the hip was normal in most patients. Average CE angle was 1.1?(?15?-15?); the Tonnis osteoarthritis grade was Ⅰto Ⅱ. Fifty three percent of the hips had Shentons line broken. Results Twenty four hips had 12 to 38 months followed up. Most patients were pain free; the hip ROM remained normal. Harris hip score increased from 79.8(64-83) pre operatively to 93.8(75-100) post operatively. CE angle increased to 40?(20?to 60?). Shentons line broken rate decreased to 33%. The complications include: 1 femoral nerve damage, 1 bladder malfunction and 2 skin incision hernia. Conclusion The Bernese periacetabular osteotomy through ilioinguinal approach is a safe and efficient procedure for the treatment of adult acetabular dysplasia. The deformities could be easily corrected, the anatomic relations could be restored nicely, the pelvic ring and the abductor muscles are reserved. The post operative recovery is fast, and it is efficient to prevent the development of osteoarthritis of the hip joint.

In recent years, the problems about the protection of intellectual property rights on the traditional medicine has got attentions around the world. Among them, Thailand explored a set of national legislations to protect the intellectual property right about the traditional medicine knowledge, which is very instructive to the developing countries. On the basis of summing up the Thailand traditional medicine intellectual property protection policy, the thesis proposed ideas on the protection of the traditional medicine in China.

AIM: To elucidate whether the mechanism that L-arginine can relieve hypoxia pulmonary hypertension involves inhibition of the activity of protein kinase C(PKC). METHODS: Twenty-one male Wistar rats were randomly divided into NS control, hypoxia and L-arginine(500 mg?kg -1 ?d -1 , ip) treatment groups. After two-weeks treatment, mean pulmonary artery pressure (mPAP), mean systematic artery pressure (mSAP) and the ratio of the weight of right ventricle to that of left ventricle plus septum were measured, then two pulmonary arterial rings were isolated to be exposed to PDBu(a specific activator of PKC ) and observed: (1) The maximal response (P 1) to 500 nmol/L PDBu, the time required to achieve a half-maximal response to 500 nmol/L PDBu (t 1/2 ), the time during which the maximal response to 500 nmol/L PDBu maintained (T) and the isometric responses at different times (2, 4, 8, 12, 20, 40, 60, 80 min). The isometric response was represented as the percentage of the maximal response (P 0) of the same arterial ring to 5?mol/L phenylephrine hydrochloride (P 0%). (2) Dose-response curve in response to PDBu (10-11 000 nmol/L) and the dose producing a half-maximal response in the curve (EC 50 ). RESULTS: mPAP, RV/(LV+S), P 1, T and the isometric responses at 2, 4, 8, 20 min of NS control and L-arginine treatment groups were lower than those of hypoxic group respectively (P
