0.05);Compared with the control group, the time of first stage(403?135) min and the total time of labor(455?148) min were shorter ( P

Cyclooxygenase (COX) is a crucial enzyme in the biosynthesis of prostaglandins.There are two COX isoforrns:COX-1 and COX-2.Recently it is demonstrated that there is a close relationship of COX-2 with the occurrence,development and metabasis of tumor; COX-2 inhibitor is hoping to be a new target in tumor therapy.The article overviews many progresses of COX-2 about its expression,modulation and mecha-nism of carcinogenesis in cholangiocarcinoma in order to explore the prospect of the COX-2 inhibitors in cholangioearcinoma treatment.

Objective To study the relationship among hydrops fetalis(over 28 gestational weeks),Mirror syndrome and preeclampsia(PE). Methods Clinical data of 13 cases of hydrops fetalis were analyzed and relative publications were reviewed. Results Eight out of the 13 cases were diagnosed as PE,and 5 were Mirror syndrome.Serious maternal complications occurred in all cases with either Mirror syndrome or PE. ConclusionsFetaland placental hydrops was closely related with maternal symptoms.Clinicians should be aware of this condition and detect Mirror syndrome in time so as to prevent its progress to PE.However,the pathogenic mechanism remains to be fully elucidated.More attention should be paid to both mothers and the hydrops fetalis.

Background and purpose:The mechanism of vinorelbine is inhibition of microtubule protein assembly and inducetion of the disaggreation of microtubles;where as docetaxed promotes the assembly of microtuble protein and inhibits normal physiological disaggreation of tubulin.We studied the curative effect and toxicity of combination of chemotherapy with navelbine(NVB) plus paclitaxel in the treatment of advanced breast cancer.Methods:Forty-two pathologically and cytologically proved cases of advanced breast cancer were treated with intravenous infusion of navelbine 25mg/m~2 on d1 and d8,paclitaxel 175mg/m~2 by 3-hour continuous infusion on d1.Interval between each cycle was 21 days and the clinical response and the toxicity were assessed after 2~4 cycles.Results:The overall response rate(RR) for the whole group of patients was 66.7% with 16.7% complete response(CR).In the first time chemotherapy patients,the RR was 72.2% with 27.2% CR;while in those with prior chemotherapy,an RR as high as 62.5% with 8.3% CR was also obtained.The 2-and 4-year survival rates was 40.5% and 21.4%,the median remission period was 8 months,the median overall survival duration was 18 months.The major side effects include leukopenia,hairloss,milieu phlebitis.Conclusions:The combination chemotherapy with navelbine and paclitaxel in treatment of advanced breast cancer is effective and the side effects could be tolerated.

Objective To analyze electrophysiology of peripheral nerve in uremic patients. Methods 24 uremic patients and 19 normalvolunteers were included, surface electrodes were used to observe the electrophysiology performance, including tibial nerve, peroneal nerve,sural nerve and skin sympathetic response. Results The motor conduction, sensory conduction and skin sympathetic response were significantlydifferent between uremia patients and normal volunteers (P<0.05). The electrophysiology performance showed that F wave latencyprolonged, nerve conduction slowed, distal latencies prolonged, sensory fibers damaged more serious than motor fibers. Conclusion Peripheralneuropathy is one of the most common complications in uremia patients, neural electrophysiological abnormalities are significantly earlierthan clinical symptoms, nerve electrophysiological examination is of great significance in diagnosis and evaluation uremic peripheralneuropathy.

The paper discusses critical factors for the successful introduction of information and communication technologies(ICT)into health care organisations．The proven evidence around the world suggests that introducing health ICT is a mutual transformation process that actively involves people, organisation and technology．The key people factors include personal attributes of the change agent, user ownership and positive user attitudes．The organisational facilitators are adequate funding, strong leadership and project management, integration of IT with work practices, managing change and end user expectations, and end user training and support．User friendly and useful systems can be achieved by involving both management and frontline health care workers in requirements analysis, system selection or prototyping, development and implementation．

To ensure the introduction of a health information system (HIS) is on track and will bring in the ex-pected outcomes, it is essential to evaluate the critical success factors at every stage of the system introduction life cy-cle. Based on comprehensive literature research and personal experience of evaluating HIS, the author proposes a multi -method approach that incorporates both quantitative and qualitative research, conceptualized through the DeLone and McLean Information Systems Success Model. The advantage of this approach is not only identifying the factors impacting on implementation success, but also distinguishing the critical factors from the less important ones.Thus it will facilitate management in prioritizing effort to address the key challenges at different stages of system introduction. This evidence -based management decision support will reduce the failure rate and maximize the benefits of HIS investment.

Objective To explore post-operative treatment and intensive care of infants with congenital heart disease(CHD).Methods Clinical data of post-operative treatment and intensive care in 264 infants with CHD were analyzed retrospectively from May.1998 to Apr.2006.Among them,256 cases underwent radical operation,and 8 cases with palliative operation.Results Sixteen cases died early.Among them,after operation,there were 8 cases with Fallot′s syndrome,2 cases with complete atrioventricular canal anomalous,3 cases with ventricular septal defect(VSD)and pulmonary hypoplasia(PH),1 case with tricuspid atresia,1 case with single ventricle,and 1 case with persistent truncus arteriosus.Causes of death include low cardiac output,acute renal failure,degree of Ⅲ atrioventricular block(AVB),lung infection,respiratory failure and arrhythmia.One case with complete pulmonary vein ectopia was discharged due to post-opertative refractory hypercapnia;1 case with atrial septal defect(ASD)and patent ductus arteriosus(PDA) died of refractory heart failure due to high pulmonary arterial pressure 1 year after operation;1 case with tetralogy of Fallot died of lung hemorrhage after radical correct operation followed by palliative outflow tract deo-ppilant operation.Of them 245 cases alive,there were 233 cases with heart function grade Ⅰ,12 cases with grade Ⅱ.Conclusion Correct management of respiratory system,systemic electrocardial care,handling with arrhthymia on time,low cardiac output and nutritional support are the important measures in improving survival rate of infants with CHD.

Objective:To study new dosage form of Bingpeng powder referring to oversea patent. Methods: To disperse Bingpeng powder, adhesive and viscosity builders (such as gelatin, carboxymethylcellulose, hypromellose or carbomer), nonionic emulsifier (gluceryl monostearate) and white vaseline into liquid paraffin, stir to attain paste. The formulation was screened by adhesive strength, shape keeping characteristic and water asorbing value. Results: The better formulation: Bingpeng powder 5.0g, hypromellose 21.0g, carbomer 14g, gluceryl monostearate 3.0g, white vaseline 7.0g, liquid paraffin to 100.0g; the paste getting rabbits' artificial ulcers healed more quickly than powder does. Conclusion: The paste is applied more expediently and more effective for oral ulcer.
