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.

ObjectiveTo elucidate the association between RANKL rs7984870 C ＞G polymorphism and the susceptibility to rheumatoid arthritis in a Chinese Han population.MethodsGenotypes were determined by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) method in 214 rheumatoid arthritis cases and 478 controls.ResultsThe RANKL rs7984870 C＞G genotype frequencies were 27.3% ( CC),51.2% ( CG),21.5% (GG) in the rheumatoid arthritis group and 25.3% (CC),49.1% (CG),25.7% (GG) in the control group respectively; Logistic regression analyses revealed that the risk associated with RANKL rs7984870 C＞G variant genotype was 0.78 (95% CI =0.49-1.24) for RANKL rs7984870 GG compared with its wild-type homozygote.ConclusionRANKL rs7984870 polymorphism may not serve as a risk factor of rheumatoid arthritis susceptibility.Further functional studies are warranted to verify our findings.

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.

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.

AIM: To explore the effects of levcromakalim(Lev) on pulmonary arterial endothelial cells (PAEC) and smooth muscle cells (PASMC) exposed to hypoxia and the mechanisms involved. METHODS: The effects of Lev on i, and expression of PKC ?, eNOS, iNOS and PDGF-B mRNA and protein levels were observed. The nitrite (NO- 2) and entothelin-1(ET-1) concentrations in supernatant in cultured PAEC and PASMC were measured. The proliferation and apoptosis of PASMC was also detected. RESULTS: When PASMC were exposed to hypoxia, Lev reduced concentration of ET-1 in cultured cell supernatant, lowed the expression of PKC ?, iNOS and PDGF-B both at mRNA and protein levels, decreased i concentration, increased proliferation and promoted the apoptosis in PASMC. However, in the presence of Lev, the i concentration was not changed in the hypoxic PAEC. The NO- 2 concentration in cultured cell supernant and expression of eNOS at mRNA and protein levels in hypoxic PASMC and PAEC were also unchanged. The downregulated ET-1 activity in PASMC and PAEC and proliferation in PASMC involved in the inhibition of PKC ? signaling pathway. CONCLUSIONS: Lev reduce some disadvatage effect of hypoxia on PASMC and PAEC. The mechanism of Lev action may partly involve in the downregulation of PKC ? signaling functions.

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 Shentons 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?). Shentons 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.
