Objective To evaluate the changes in the epidemiology and clinical characteristics of cervical carcinoma over the past 50 years, and to explore the equitable treatment corresponding to these changes. Methods The clinical and pathological data of 1557 patients with invasive cervical carcinoma from January 1955 to December 2004 were retrospectively analyzed. Results (1) The average age of cervical carcinoma onset gradually decreased over the past 50 years, from 56.27?8.45 in years 1955~1964 to 43.81?8.9 in years 1995~2004. At the same time, the radio of clinically early (stages Ⅰ-Ⅱ) and non-squamous cancer also steadily increased. (2) Young patients (≤35 year old) had higher ratios of non-squamous, poorly differentiated and late stage (Ⅲ-Ⅳ) cancers, with a higher rate of lymphatic metastasis compared with other ages. (3) Because of the changes in epidemiology and clinical characteristics of cervical carcinoma, it′s necessary to alter the traditional model of treatment and to explore equitable therapy corresponding to these changes. Conclusions The average age of cervical carcinoma onset gradually decreased and simultaneously the ratio of clinically early (stages Ⅰ-Ⅱ) and non-squamous cancer also steadily increased over the last 50 years. Patients aged 35 and younger of cervical carcinoma had some obvious clinical characteristics compared with that of older patients. Preservation of reproductive endocrine function ought to be deliberated on in cervical carcinoma treatment of women with fecundity. Neoadjuvant intraarterial chemotherapy (NAIC) is an useful method for cervical carcinoma at present

The 4 kinds of gaseous signal molecules——nitric oxide,carbon monoxide,hydrogen sulfide and sulfur dioxide,which were discovered by people consecutively,all played significant pathophysiological roles in the cardiovascular system.With the pathogenesis of pulmonary artery hypertension(PAH) being illuminated uninterruptedly,gaseous transmitters and the interaction between them become the hot issue in the domain.This article summarized the mechanism of gaseous signal molecules in the formation process of PAH,in order to identify that during the morbidity process of PAH gaseous transmitters took effect in network regulating model.It also possessed great significance to comprehend the pathophysiological variation of PAH profoundly.

Endoplasmic reticulum stress is another kind of sub-cell level stress which is discovered after nuclear stress and mitochond-rial stress.Endothelial cells,macrophages and smooth muscle cells play important roles in the formation of atherosclerosis.Endoplasmic reticulum stress participate the occurrence and development of atherosclerosis by regulating the inflammatory response,lipid metabolism and apoptosis of the above cells.

Objective To investigate the relationship between day-night rhythm of blood pressure and left ventricular hypertrophy(LVH) in the elderly with hypertension. Methods According to the result of ambulatory blood pressure monitoring,60 patients were divided into two groups of normal day-night rhythm(n=34) and abnormal day-night rhythm(n=26).All patients were performed ultrasonic cardiography.The interventricular septal thickness(IVST),the left ventricular end diastolic dimension(LVDd)and the left ventricular posterior wall thickness(LVPWT) were recorded,and the left ventricular mass(LVM) and the left ventricular mass index(LVMI) were calculated according to the Devereux formula. Results There were no significant differences in age,body mass index,serum total cholesterol,triglyceride,fasting blood glucose,24 h mean systolic blood pressure,24 h mean diastolic blood pressure,day time mean systolic blood pressure,day time mean diastolic blood pressure,IVST and LVDd between the the two groups.However,there were significant differences in night time mean systolic blood pressure,night time mean diastolic blood pressure,LVPWT,LVM and LVMI between the two groups(P

?AIM:To investigate the measurement of central anterior chamber depth ( ACD ) in patients with acute primary angle - closure glaucoma ( APACG ) with A - scan ultrasound, Pentacam and ultrasonic biological microscope ( UBM) .?METHODS: Thirty-five patients (35 eyes) with APACG were selected, of whom central ACD were measured with A-scan ultrasound, Pentacam and UBM.?RESULTS: The measurement values of ACD with A-scan ultrasound, UBM and Pentacam were 1. 5633±0. 2089, 1. 5783 ± 0. 2067, 1. 6275 ± 0. 2296mm, which was equal variance tested by the homogeneity of variance, and was significant different by multiple comparision (F=4. 074, P=0. 026). The difference of ACD between the two groups of A-scan ultrasound and UBM, A-scan ultrasound and Pentacam, UBM and Pentacam were statistically significant ( P = 0. 032, 0. 023, 0. 012 ). Altman- Bland analysis showed that the three methods were not consistent with each other.?CONCLUSION: The ACD value of the APACG with the three methods is the largest using Pentacam, followed by UBM and A - scan ultrasound. In clinical the three methods with different advantages can complement each other, but cannot be replaced. In order to obtain more accurate results, we should combine the advantage and make comprehensive analysis.

Objective To observe the changes of serum ferritin (SF)in neonates with mechanical ventilation and its clinical significance in the ventilation-induced lung injury (VILI). Methods The study was carried out in 36 neonates with mechanical ventilation and 31 neonates without mechanical ventilation in neonate intensive care unit(NICU).SF level in venous blood was measured on 1,24,48,72 hours after mechanical ventilation and 24 hours after mechanical ventilation removal by radioimmunoassay (RIA ).SF level of non-mechanical ventilation group were determined at the same time. Results SF levels in mechanical ventilation groups were significantly higher than those of control group (P

Objective To explore the diagnostic value of endoscopic retrograde cholangio-pancreatiography (ERCP),ultrasonography (US) and CT scanning on cholagio-pancreatic diseases caused by clonorchis sinensis infection.Methods The results of US,CF and ERCP examination in 65 cases of obstructive jaundice caused by clonorchiasis and confirmed by presence of imagoes or eggs in feces or bile juice were analyzed and compared retrospectively.Results US examination was the simplest and most convenient which was characterized by diffuse even dilatation,thickening of walls,strengthened echo with the shape of“equal sign”intrahepatic bile ducts.The characteristic findings of CT included saccular dilatation of bile ducts of the periphery of the liver,thickening of the walls of bile ducts.Under duodenoscopy,32.3% (21/65) of cases presented as abnormal papilla such as small opening,mucosa outward turned,trapping or stiffness.Alterations in ERCP were characterized by shm or oval filling defect,diffuse saccular dilatation of terminal intrahepatic bile ducts.The most common complications included cholangiolithiasis (40%,26/65),carcinoma of bile duct on papilla (9.8%,6/65),and pancreatitis (1.5%,1/ 65).Conclusions Three methods were all useful for diagnosis of cholangio-pancreatic diseases caused by clonorchis sinensis infection,which were identically characterized by diffuse saccular dilatation of terminal intrahepatic bile ducts.The gold standard of diagnosis was the presence of imagoes or eggs in bile juice aspirated by the route of ERCP.Endoscopic sphincterectomy with postoperative vermifugal was the first choice of the treatment.

Objective To investigate the therapeutic effects of Smad7 and urokinase-type plas- minogen activator(uPA)co expression on CCl_4-induced rat liver fibrosis.Methods Forty SD rats were subcutaneously injectied of 40% CCl_4 every three days for 8 weeks.The rats were then divided into model group,AdSmad7/uPA group(injected with AdSmad7/uPA via tail vein),AdSmad7 group(injec- ted with AdSmad7 via tail vein)or AdGFP group(injected with AdGFP via tail vein).Ten healthy rats were served as control.The serum levels of procollagenⅢ(PCⅢ)and laminin(LN)were determined by radioimmunoassay,and the hydroxyproline level in liver tissues were examined by alkaline hydrolysis. The expressions of Smad7 and uPA in tissue were examined by immunohistochemistry and fibrosis area was stained with Sirius red.Results The expressions of Smad7 and uPA protein were significantly higher in AdSmad7/uPA group than that in AdGFP group after 3 days.Serum levels of ALT,AST,PCⅢand LN were significantly decreased in AdSmad7/uPA group compared to Smad7 and AdGFP groups (all P value
