Objective To analyze the clinical efficacy of compound 18 norgestrel combined with estrogen in treatment of dysfunctional uterine bleeding. Methods 78 cases of patients with dysfunctional uterine bleeding in Beijing Ji Shui Tan Hospital and Dongguan city people's hospital of guangdong Province were divided into control group (n=39)and observation group (n=39)by using randomized single-blind allocation. The control group was only given estrogen,the observation group was used compound 18 norgestrel combined with estrogen. The clinical efficacy of the two groups was compared. Results 31 cases were cured and 7 cases were valid of the study group,the total effective rate was 97.4%,significantly higher than the control group's total efficiency of 71.8%,the difference was statistically significant (P<0.05). Each index of observation group and the control group were improved after treatment,the difference was statistically significant (P<0.05 );After treatment,the menstrual cycle in observation group was (29.7 ±7.1)d,the menstrual period was (5.6 ±0.5)d,hemoglobin content was (135.5 ±21.7)g/L,endometrial thickness was (0.63 ±0.15)mm, significant changes than the control group,the difference was statistically significant (P<0.05 ). Conclusion Compound 18 levonorgestrel combined with estrogen has a better effect in patients with dysfunctional uterine bleeding and it can significantly improve patients'hemoglobin,the menstrual cycle and the uterus film thickness and other indicators which is worth promoting in clinical.

A 41 years female patient was hospitalized with hoarseness for three months, without cough, expectoration and dyspnea. The symptom had no relief by application of antibiotics. Electronic laryngoscope showed that there were the grey neoplasms under subglottic anteriou commissure with broad base and slightly rough surface, and bilateral vocal cords were normal; throat CT showed subglottic irregular high density and calcification. The subglottal tumor resection was performed under the general anesthesia and laryngoscope CO2 laser assisted. In the operation, we found that the tumor was hard with surface of thin mucosa tissue, and there was white bone tissue under it. The removing tumor was about 0. 8 cm X 0. 6 cm X 0. 3 cm and was diagnosed as subglottic osteoma by pathologic examine. There was no recurrence in three months follow-up.

Objective To investigate the extent and the relevant factors for local lymph node metastasis of gallbladder carcinoma. Methods Clinicopathologic features of 34 patients with gallbladder carcinoma who underwent radical resection were analyzed retrospectively. Results The overall lymph node metastasis rate was 68%(23/34), with 0(0/3) in T 1 stage, 43%(3/7) in T 2, 85%(11/13) in T 3, and 82%(9/11) in T 4. The metastasis rate was 29%(10/34) in gallbladder lymph nodes, 44%(15/34) in pericholedochal, 18%(6/34) in hepatic hilum, 24%(8/34) alongside proper hepatic artery, 21%(7/34) in periportal vein, 38%(13/34) in retropancreaticoduodenal, and 4/6 in paraaortic region. Conclusions Lymph node metastasis was determined by the depth of invasion of the primary tumor. The extent of surgical dissection was made according to the exploration and result of intraoperative biopsy.

Objective To evaluate the efficacy and safety of oral ibuprofen for closure of patent ductus arteriosus (PDA) in preterm infants.Methods The related literatures till December 31st,2011 in Cochrane Library,PubMed,EMBASE,Ovid,Springer,China Academic Journal Full-text Database,Wanfang Database,VIP Database and China Biological Medical Literature Database were searched.The inclusion criteria were:(1) the subject of the research was preterm infants with birth weight less than 2500 g and/or gestational age less than 37 weeks; (2) randomized or semirandomized controlled trial; (3) the intervention group received oral ibuprofen,while the control group received oral placebos / intravenous indomethacin or ibuprofen; (4) the main outcome was the failure rate of PDA closure; (5) hemodynamic changes with PDA were detected by ultrasonography.Meta-analysis was performed by Review Manager 4.22 software.Results Eleven randomized controlled trials were included,among which,three were high quality reports.Meta-analysis showed lower failure rate of PDA closure in subjects received oral ibuprofen than in those received placebos orally (RR =0.22,95 ％ CI:0.14-0.35),while the number of infants required operative closure of PDA decreased significantly (RR =0.16,95％ CI:0.03-0.86).Further analysis showed the effect of oral ibuprofen was similar to intravenous indomethacin (RR =0.93,95 ％ CI:0.57-1.53),but better than intravenous ibuprofen (RR=0.42,95％CI:0.26-0.67).However,oral ibuprofen did not reduced the ratio of patients required operation compared with intravenous indomethacin or ibuprofen (RR=0.58,95％CI:0.24-1.41).The incidence of gastrointestinal hemorrhage was higher in oral ibuprofen group than that in placebos(RR=1.99,95％CI:1.13-3.50).The serum level of creatine was lower in oral ibuprofen group than in intravenous indomethacin or ibuprofen group (weighted average=-19.10,95％ CI:-25.12-12.31).Compared with intravenous indomethcin group,less necrotizing enterocolitis cases were identified in oral ibuprofen group,but no statistical significance was found (RR=0.57,95％ CI:0.30-1.09).No long-term outcome was reported in any selected literature.Conclusions Oral ibuprofen for PDA closure in preterm infants appears to be as effective as intravenous or indomethacin,and more effective than intraveous ibuproten.Oral ibuproten represents better safety.

Objective:To determine the characteristics and differences in bleomycin-induced lung ifbrosis model by repeated low-dose intravenous injection and single dose intratracheal instillation of bleomycin.
Methods:Forty male ICR (Institute for Cancer Research) mice were randomly divided into a model group I, a model group II, and 2 control groups (10 mice in each group). In model group I, bleomycin was injected intravenously at 10 mg/(kg·d) for 14 consecutive days;and in model group II, bleomycin was instilled intratracheally at 5 mg/kg. The 2 control groups were given isotonic saline solution. At the 28th day, the mice were sacrificed and the bronchoalveolar lavage lfuid (BALF) was collected. The total cells and proteins in the BALF, pulmonary coeffcient, and hydroxyproline (HYP) content were determined. The pathological changes were observed by the eosin staining and Masson's trichrome staining.
Results:1) Both intravenous injection and intratracheal instillation of bleomycin resulted in severe and extensive inlfammation and ifbrosis in the lungs. The total cells and proteins in the BALF, HYP content, pulmonary coeffcient and the pathological score of pulmonary ifbrosis were all signiifcantly increased in the 2 model groups (P<0.01). 2) Fibrosis was mainly under the pleura or around the vessel in model group I, and it was located near the bronehia and bronchioles in model group II. 3) The death rate was higher in the model group II than that in the model group I. 4) Proteins in the BALF were significantly higher in model group II than that in model group I (P<0.05). There was no difference in the total cells in the BALF, the pulmonary coefficient, the HYP content, and the pathological score of pulmonary ifbrosis between the 2 groups (P>0.05).
Conclusion:The pulmonary fibrosis model can be successfully established by intravenous injection or intratracheal instillation of bleomycin, but the sites of pulmonary ifbrosis are different. The histological changes caused by the repeated low-dose intravenous injection of bleomycin is more similar to idiopathic pulmonary ifbrosis than that by the single dose intratracheal instillation.

Objective To evaluate the diagnostic values of MRA,TCD and ultrasonography in carotid territory transient ischemic attacks (TIAs). Methods 42 patients with carotid territory TIAs were examined by MRA, TCD and ultrasonography. Results MRA showed abnormalities of carotid arteries in 12 cases (28.6%) and abnormalities of intracranial arteries in 32 cases (76.2%). 8 cases presented abnormalities both in carotid arteries and intracranial arteries. Abnormalities of intracranial arteries were detected by TCD in 30 cases (71.4%) and abnormalities of carotid arteries were detected by ultrasonography in 16 cases (38.1%).Conclusion MRA, TCD and ultrasonography are useful in the evaluation of etiological factors of carotid territory TIAs.

Objective: To examine the effect of Benapril on atherogenesis and the plaque rupture in rabbits.Methods: Thirty four healthy male New Zealand white rabbits were randomly divided into 4 groups.Group C (control group) was fed normal diet for 10 weeks,group HL fed 1% cholesterol diet,group B fed 1% cholesterol diet and Benapril 5 mg/d.Ten rabbits of plaque rupture group were fed 1% cholesterol diet for 10 weeks with atherosclerosis induced by left carotid iliac damage.Ten weeks after the initiation of the diet,an angioplasty was performed.After angioplasty,the surviving rabbits( n =10) were randomized to receive benapril(5 mg/d,each) supplementation in drinking(B group, n =4) or no treatment(untreated group, n =4). The levels of CEC were measured by morphometrical counts at different periods(the 5th week,the 10th week).Before and 5,10 weeks after experiment,fasting blood samples were collected for serum total cholesterol(TC),high density lipoprotein cholesterol(HDL C),low density lipoprotein cholesterol(LDL C),and triglyceride(TG) assay.The levels of plasma circulating endothelial cells(CEC) were measured by morphometrical counts and the levels of plasma von Willebrand factor(vWF) were determined by ELISA.After sacrificing the separated, entire aortas were stained with oil red O and then processed for histological examination;planimetry was done with a computer system.Endothelial cells were confined by the presence of Factor Ⅷ related antigen as the specific cell marker.Results: The serum TC,TG,LDL C increased progressively in group B and group HL,but the levels of vWF in group HL were significantly higher than that in group B on the 5th and 10th respetively( P

Objective To determine the relationship between serum adiponectin level and chronic inflammation,atherosclerosis in maintenance hemodialysis(MHD)patients.Methods Totally 60 MHD patients and 30 healthy volunteers were included in this study.Serum adiponectin level(ADPN)and C-reative protein(CRP),interleukin-6(IL-6)were measured.Carotid initial-medial thickness(IMT)and brachial arterial vasodilation were determined by echocardiography.Results Serum ADPN level(0.99?0.37)was higher in MHD patients than that(0.39?0.14)in controls.The ADPN level of higher IMT group was lower than that in normal IMT group.CRP,IL-6 and Cartid IMT were negatively correlated with ADPN(r=-0.22,-0.31-0.26,P

Objective To investigate the protective effects of transection of the cervical sympathetic trunk (TCST) on the gastric mucosal lesions in rats fastened to a board and immersed vertically in water, up to the level of xiphoid with the animals' heads up water for 6 hours. Methods Thirty male SD rats weighing 200-250 g were randomly divided into 3 groups ( n = 10 each): group A sham operation; group B sham operation + water immersion and group C TCST + water immersion. The animals were anesthetized with intraperitoneal 2.5% pentobarbital 40 mg?kg-1. Cervical sympathetic trunk was exposed at right common carotid artery bifurcation and cut. The gastric mucosal blood flow (GMBF) was measured with Doppler blood flow monitor after 6 h water immersion. Blood samples were taken from abdominal aorta for determination of plasma concentration of ET-1 and serum concentration of NO. Gastric mucosal ulcer index was determined according to Guth criteria.Results There was gastric mucosa bleeding and erosion in group B and C and the degree of injury was severer in group B than in group C. Plasma concentration of ET-1 and serum concentration of NO were significantly higher in group B than in group C and A.Conclusion TCST has protective effect on gastric mucosal blood flow in rats under stress by reducing blood ET and NO concentrations.
