Objective To investigate the effect of a selective inhibitor of COX-2 nimesulide on growth and apoptosis of human cholangiocarcinoma cell line QBC939 in vitro. Methods MTT assay was used to determine the influence of nimesulide on the proliferation of QBC939 cells, apoptosis of QBC939 was measured by transmission electron microscopy and flow cytometry.Expression of apoptosis related genes mRNA and bcl-2 ,bax, survivin were detected by RT-PCR and immunocytochemistry. Results Nimesulide effects a dose-dependent and time-dependent growth inhibition on QBC939 cells. High concentration of nimesulide (200 ?mol/L) not only inhibits the growth of QBC939 cells but also induces apoptosis cell nuclear condensation and apoptotic bodies were seen by transmission electron microscopy. Immunocytochemistry and RT-PCR shows upregulation of bax and down regulation of bcl-2 and survivin. Conclusion Nimesulide significantly inhibits the proliferation of QBC939 in vitro by induction of apoptosis in a dose- and time- dependent manner.

Objective To investigate the effects of nimesulide, a selective cyclooxygenase-2 (COX-2) inhibitor, on human cholangiocarcinoma QBC939 cell line in vitro. Methods The effects of nimesulide on QBC939 cells were observed with the following techniques: the influence of nimesulide on the proliferation of QBC939 cells was determined by MTT assay; the apoptosis of QBC939 cells was viewed and measured by transmission electron microscopy and flow cytometry, respectively; the expressions of proliferation cell nuclear antigen (PCNA) and COX-2 of cholangiocarcinoma cells were detected by immunocytochemistry. Results Nimesulide inhibited the expressions of PCNA and COX-2 and the proliferation of cholangiocarcinoma QBC939 cells, whose effects intensified as the dose increased and time elongated. Flow cytometry showed that the apoptotic rates of QBC939 cells increased significantly as the dose of nimesulide increased. The typical morphologic features of apoptosis were also observed by transmission electron microscopy. Conclusion Nimesulide significantly inhibits the proliferation of QBC939 cells in vitro by inducting cell apoptosis, which may be associated with the downregulation of COX-2 expression, and it also presents the features of dose and time dependents.

Objective To study the effect of pulse pressure(PP)/mean artery pressure(MAP) ratio in evaluating arteriosclerosis.Methods Blood pressures from 200 subjects without cerebrovascular nor cardiovascular disease were obtained and analyzed by different age groups.PP/MAP ratio was calculated for each patient and compared.Results PP/MAP ratio was significantly different in different age groups.Conclusion PP/MAP ratio has clinical significance in evaluating arteriosclerosis and is worthy of further investigation.

The demand of hospital car in first-aid and patients carrying is urgent in paroxysmal epidemic,disaster and wartime.According to types and characteristics of civil-train,many methods are used to rapidly refit civil-train to hospital car,such as rapid taking down devices from civil-train,installing medical appliances and unloading the device in the civil-train and auxiliaries.Based on analysis and comparison,YZ25G hard-seat train is the best one to refit from civil-train to hospital car.

Objective To investigate the value of ionic-contrast esophagogram in diagnosis of intrathoracic anastomotic leakage after oesophagectomy.Methods The data of 728 patients suffered esophagectomy were retrospectively collected.723 patients without clinical manifestations of anastomotic leakage were divided into group A(esophagogram before eating,n=465) and group B(non-esophagogram before eating,n=258).The incidence of anastomotic leakage was compared between the two groups.Results The discovery rates of anastomotic leakage in group A and B were 0.43%(2/465) and 0.78%(2/258),respectively,the difference was no statistically significant between the two group(P=0.55).The total incidence rates of anastomotic leakage in group A and B were 0.65%(3/465) and 0.78%(2/258),respectively,the difference was no statistically significant between the two groups(P=0.84).5 patients with clinically suspected anastomotic leakage,all had loculated pleural effusion,4 cases had fever,and 2 cases had abnormal chest drainage.Finally,4 cases(80%) were confirmed to be anastomotic leak by esophagogram.Conclusion Routine ionic-contrast esophagogram before eating do not improve intrathoracic anastomotic leakage detection rate after esophagectomy,but when patients have fever,loculated pleural effusion and abnormal chest drainage,esophagogram is necessary and can improve the detection rate of esophageal anastomotic leak.CT radiography may detect smaller anastomotic leakage than conventional esophagogram.

Objective To observe the clinical efficacy and safety of Chushi Huowei Decoction in treating inflammation of gastric relict of spleen-stomach damp heat type. Methods Totally 62 patients with inflammation of gastric relict were divided into treatment group and control group with random number table, 31 patients in each group. The control group was given hydrotalcite and the treatment group was treated by adding of Chushi Huowei Decoction. After eight-week treatment, the clinical efficacy, gastric mucosal lesions efficacy, and gastric mucosal pathology efficacy of the two groups were compared. Results Eight-weeks later, traditional Chinese medicine symptom scores of both groups were obviously lower than those before treatment (P<0.01). And the decrease in the treatment group was more obvious than that in the control group (P<0.01). Curative effects of gastric mucosal lesions and pathologic condition in treatment group were better than those in the control group (P<0.05, P<0.01). Neither groups had any adverse reaction. Conclusion Chushi Huowei Decoction has reliable therapeutic effect and safety in treating inflammation of gastric relict of spleen-stomach damp heat type.

Objective To estimate the prevalence of thyroid dysfunction among the retired staffs of a petrochemical corporation in Ningbo. Methods The 1709 retired staffs at 60 years of age and over were enrolled in the census. Their medical history were investigated by questionnaires,and blood samples were collected for thyroid function detection. Results In this elderly cohort, the morbidity of diagnosed thyroid diseases was 3.8% (65/1709), with 6.7% (39/584) in females and 2. 3% (26/ 1125) in males. The morbidity of unrecognized thyroid dysfunctions was 6.7% (110/1644), with 9.7% (53/545) in females and 5.2% (57/1099) in males. The prevalence of total thyroid dysfunctions was 10. 2%(175/1709), with 15.8% (92/584) in females and 7.4% (83/1125) in males. Subclinical hypothyroidism accounted for 87. 3% of unrecognized thyroid dysfunctions. Conclusions The prevalence of thyroid dysfunctions is over 10. 2% in the elderly retired staffs of the petrochemical corporation in Ningbo. Subclinical hypothyroidism is the most popular form in all kinds of unrecognized thyroid functional disorders, and its prevalence is higher in females than in males.
