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 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 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.

Objective To investigate the therapeutic effect and side effect of prourokinase (Pro-uk) on the patients with acute myocardial infarction. Method From May 2004 to May 2005, a total of 68 cases of acute myocardial infarction treated by thrombolytic agents within 6 hours after onset were divided randomly into Pro-uk group ( n = 43) and urokinase (UK) group ( re = 25). In the Pro- uk group, there were 22 eases treated with 50 mg Pro-uk and 21 cases prescribed in 60 mg Pro-uk. The patency of involved coronary artery was evaluated by using selective coronary angiography at 90 minutes after thrombolytic therapy. The incidence of early heart events, bleeding and adverse reaction, were alse observed. Results (1) The total rates of resumed patency of obstructed coronary artery (TIMI grade 2 and 3 flow) were 76.7% in Pro-uk treated patients and 52.2% in UK treated patient ( P = 0. 041). (2) The occurrence of hyporrhea was lowered more significantly in Pro-uk treated patients than in UK treated patients (P = 0.029), but there were no intracranial hemorrhage found in both group. (3) Early cardiac events and adverse reactions were similar between two groups. Conclusions Pro-UK is safe and effective for the patients with acute myocardial infarction.

Objective To evaluate eutopic endometrial blood supply and vessels in patients with endometriosis(EMs) with contrast enhanced ultrasound (CEUS),to explore a newmethod to estimate vascularization of eutopic endometrium in EMs patients.MethodsThirty patients with EMs were enrolled and 20 patients who were diagnosed as other gynecological diseases as control.Informed consent of each case was obtained. AllcasesunderwentconventionalultrasoundexaminationandCEUSexamination.Characteristics of CEUS in each patients were observed and analyzed using off-line Qontrast software.Parameters of CEUS including peak intensity(PEAK),time to peak(TTP),regional blood volume(RBV),regional blood flow(RBF) were obtained automatically.ResultsComparing with control group,the eutopic endometrium in EMs group presented higher enhancement.The parameters of CEUS,including PEAK,TTP,RBV,RBF were (41.18 ± 3.29) dB,(29.01 ± 4.46) s,(29.07 ± 4.59) ml,(48.61 ± 5.35) ml/min in EMs group and (13.36 ± 2.34)dB,(24.59 ± 2.29)s,(26.51 ±- 3.80)ml,(48.71 ± 3.80)ml/min in controls respectively,the value of PEAK in EMs group was higher than that of controls ( P =0.000).Conclusions CEUS can be regarded as a new method which can be used to assess vascularization of eutopic endometrium in endometriosis.

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.

Objective To study clinical characteristics,causes of misdignosis and diagnostic and therapeutic methods for primary hyperparathyroidism (PHPT).Methods Retrospective analysis was done for 51 patients of PHPT,47 confirmed by biopsy after surgical operation and 4 without operation diagnosed based on their serum levels of calcium,alkaline phosphatase ( ALP),intact parathyroid hormone ( iPTH ),and computed tomography (CT) or 99mtechnetium sestamibi (99mTcMIB1) imaging at the First Affiliated Hospital of Sun Yat-sen University,Guangzhou during June 1997 to November 2010.Results Bone-related complications were the most common clinical manifestation,accounting for 51％ (26/51 ) of the cases,and adenoma,a benign,enlarged and hyperactive parathyroid gland,in 34 of 47 cases ( 72％ ).In orthotopic lesions,the right inferior was affected in 19 of 46 cases (41％),followed by the left inferior in 13 cases (28％),while 5 of 51 cases (10％) with ectopic parathyroid gland.PHPT was easily misdiagnosed as urolithiasis,rheumatic disease,primary osteoporosis,etc,accounting for 92％ of the cases in our study.Preoperative serum levels of calcium,ALP and iPTH in the patients varied with their clinical type and pathological classification,the highest in patients with urolithiasis-bone-related complications [ (3.22 ±0.35) mmol/L,(1455 ± 1091 ) U/L and (1669 ± 515 ) ng/L,respectively ] and in patients with parathyroid carcinoma [ (3.46 ± 0.40) mmol/L,( 1410 ± 426) U/L and ( 1861 ± 768) ng/L,respectively ].Sensibility of preoperative localization diagnosis using ultrasonography,CT and 99mTcMIBI was 88％ (35/40),97％ (30/31) and 97％ (31/32),respectively.Conclusions PHPT is frequently misdiagnosed as other diseases.Measurement of serum calcium should be included in routine physical examinations,supplemented with measurement of serum ALP and iPTH,as well as medical imaging,which can help avoid misdiagnosis.CT combined with 99mTcMIBI imaging can improve accuracy of preoperative localization diagnosis.
