Objective To explore the relationship of zearalenone (ZEA) and precocious puberty in girls.Methods The peripheral serums from 71 cases of precocious puberty girls and 50 cases of healthy girls were collected respectively and concentrations of ZEA were detected by high performance liquid chromatography.Bone age,body mass index (BMI),volume of uterus and ovaries,concentrations of estradiol (E2),luteinizing hormone (LH) and folliclestimulating hormone (FSH) were detected,and the residence of each subject was recorded as well.Results (1) In 71 patients,52 patients were diagnosed as idiopathic central precocious puberty,others were diagnosed as premature thelarche.(2) In 71 patients,serum ZEA was detected from 51 patients,and undetected in 20 patients.(3)Concentration of ZEA in precocious puberty girls [(318 ±34) ng/L]was significantly increased than that in healthy girls [(143 ± 35) ng/L,P =0.002],but no distinct difference existed between ICPP group and PT group(P =0.326).(4)Compared with uterus volume of ZEA in the undetected patients (1.975 ±0.150) cm3,the uterus volume of ZEA detected patients (2.972 ±0.180) cm3,which was significantly enlarged,there was significant difference (P =0.01) ; Percentage of overweight girls in ZEA detected patients (31.4％,16/51 cases) was lower than which in ZEA undetected patients (65.0％,13/20 cases,P =0.01) ; Although there was no statistical differences in the breast diameter,bone age,value of E2,LH and FSH between ZEA detected patients and undetected patients (all P ＞ 0.05),but the increased tendency in ZEA detected patients existed.(5) ZEA in serum was detected in 53.3％ (16/30 cases) patients living in the cities,and the rate was obviously lower than 82.9％ of the patients (34/41 cases) living in the countryside,there was significant difference (P =0.007).Conclusions ZEA is correlated with precocious puberty in girls.ZEA pollution might be one of reasons for precocious puberty occurrence.

Objective To observe the characterization of fat emboli in cardiac chamber in pig model and the patients undergoing total hip arthroplasty(THA) by transesophageal echocardiography(TEE). Methods Different dose of fatty liquid was injected slowly via the internal jugular vein. The changes of the image were observed by continuous TEE. The lethal dose of fat embolism was recorded. Twenty-two patients underwent TEE during THA. Gray scale and echo intensity of fat embolism in right atrium were studied quantitatively in varied periods of the operation. Results With the increase of fat liquid injected in pig model, the strong- echo particles in right atrium and ventricle became more and more, the imaging of the particles was from “moving star”, “shower-like” to “snow fluffy”, at last paradoxical fat embolism occurred when the dose of fat liquid was over 4 ml. The accumulated lethal dose of fat embolism was 15.8 ～ 27.8 ml.②Fat emboli appeared as strong- echo particles in right atrium were found in different period of THA. Average gray scale and echo intensity of emboli in right atrium were significantly higher in period B than in other periods during THA. Conclusions Fat emboli in cardiac chamber can be found sensitively by TEE. Intra-operative monitoring and quantitative analysis is helpful to identifying fat embolism syndrome.Paradoxical embolism is a reliable evidence of fat embolism syndrome.

Objective To investigate the prevalence of Helicobacter pylori (Hp) infection among health checkup population in Xiamen area during 2012-2014,and evaluate the potential predictors for Hp infection.Methods A cross-sectional study was conducted among health checkup population in the Zhongshan Hospital during 2012-2014.Potential participants completed 13C breath tests for helicobacter pylori infection.An epidemiological questionnaire was used to collect data on socio-demographic characteristics,the awareness of Hp-related information,the history of gastrointestinal diseases or symptoms,life styles and relevant data for each participant.Univariate and multivariate logistic regression analyses were performed to evaluate the associations of Hp infection with potential predictors.Results Three groups of individuals with 1 631,1 766,and 5 257 persons who underwent health checkup were screened for Hp infection,and Hp prevalence was 48.9％,49.8％,and 50.5％ during 2012-2014,respectively.No significant difference in Hp prevalence was found between both sexes.A total of 1444 acceptible questionnaires were used to evaluate the associations between Hp infection and potential predictors and Hp infection was 47.9％ among 1 444 eligible participants.In the multivariate logistic regression model,Hp infection was found to be associated significantly with having ever tested for Hp infection (OR,0.67;95％CI:0.51-0.88;P=0.004),the history of stomachache or gastrectasia (OR,2.19;95％ CI:1.73-2.78;P＜0.001),and alcohol drinking (OR,1.38;95％ CI:1.11-1.71;P=0.004).The higher the severity of Hp infection,the higher the prevalence of stomachache or gastrectasia,and smoking and alcohol drinking.However,the prevalence of smoking and alcohol drinking decreased among those with the highest severity of Hp infection.Conclusion The prevalence of Hp infection in Xiamen area was slightly lower than the national Hp prevalence among natural population,but this prevalence reached 50％.The awareness rate of Hp infection was still low.The prevalence of stomachache or gastrectasia among our study population presented positive correlation with the severity levels of Hp infection.More attention should be paid to Hp screening and treatment among those with gastrointestinal diseases or symptoms.

Objective To evaluate the protection of 3-aminobenzamide (3-AB),an inhibitor of Poly (ADP-ribose) polymerase (PARP),on severe acute pancreatitis associated adenohypophysis injury in rats.Method Forty Wistar rats were randomly divided into 4 groups:sham operation group (SO group,n=8),SAP group (n=12),3-AB pretreatment group (n =12),drug control group (n =8).The bilepancreatic duct was cannulated through the duodenum and SAP model was induced by a standardized pressure-controlled retrograde infusion of 5％ sodium taurocholate (0.1 ml/100 g) into the bile-pancreatic duct.In 3-AB group,3-AB (20 mg/kg) was administered via femoral vein 30 min prior to the operation;other procedures were identical to SAP group.In SO group,pancreas was flipped several times only.In drug control group,3-AB (20 mg/kg) was administered via femoral vein 30 min prior to the operation.Serum amylase,lipase were measured.Pancreas and pituitary tissue were taken for pathological examination under light microscope.PARP and NF-κB antibodies for adenohypophysis immunohistochemical stains.Adenohypophysis cell was observed under electronic microscope.Result Serum amylase,lipase and pancreas pathological scores were significantly higher in 3-AB group compared with SO group (P ＜ 0.05),but lower than that in SAP group (P ＜ 0.05).Adenohypophysis pathological injury was less severe in 3-AB group.Expressions of PARP and NF-κB in adenohypophysis cells were significantly higher in 3-AB group compared with SO group,but lower than that in SAP group (P ＜ 0.05).Ultrastructural change of thyrotroph cell was relieved in 3-AB group.No significant difference was observed between SO group and drug control group in PARP and NF-κB expression nor adenohypophysis pathological injury.Conclusions 3-AB exerts the protective effect against acute pancreatitis associated adenohypophysis injury by inhibition of PARP and NF-κB.

Objective To investigate the changes of poly-ADP-ribose polymerase (PARP) and NF kappa B (NF-κB) in adenohypophysis in rat model of severe acute pancreatitis (SAP),and their role in the mechanism of adenohypophysis injury in SAP.Methods Forty Wistar rats were randomly (random number) divided into 5 groups:the sham operation group (SO group,n =8),SAP 1 h,3 h,6 h and 12 h groups (n =8 in each group).SAP model was induced by retrograde injection of 5％ sodium taurocholate into the biliopancreatic duct.Serum levels of amylase,lipase and ascites were measured.After sacrifice of experiment rats,pancreas and adenohypophysis tissues were taken for pathological examination under light microscope.Adenohypophysis cells were observed under electronic microscopy as well.PARP and NF-κB expressions in adenohypophysis cell was studied by using immunohistochemisty assay.Results After modelling,serum levels of amylase,lipase and ascites in SAP group increased gradually,which were higher than those in SO group (P ＜ 0.05).Adenohypophysis cell swelling and partial necrosis were observed under light microscope.As the time prolonged,their nuclei became dark and pyknotic more and more,and the endoplasmic reticulum and mitochondrial swelling in adenohypophysis cells were observed under electronic microscopy.The expressions of PARP and NF-κB in SAP group increased gradually,which were higher than those in SO group.Conclusions Significant pathological and ultrastructural injuries were observed in adenohypophysis cells in severe acute pancreatitis.These changes might correlate with PARP and NF-κB signaling pathway.

Objective To investigate the renal level of 1o-hydroxylase and the change of serum calcium in rats with severe acute pancreatitis,and their correlation.Methods Eighty male Wistar rats were randomly (random number) divided into two groups:sham operation group (SO group),severe acute pancreatitis group (SAP group),and each group was further randomly divided into 1 h,3 h,6 h,and 12 h subgroups (n =10).Severe acute pancreatitis model was made by retrograde infusion with 5％ sodium taurocholate solution into the biliopancreatic duct,rats were sacrificed at 1 h,3 h,6 h,and 12 h separately after modeling.The levels of serum amylase,serum calcium,serum urea nitrogen,serum creatinine,serum 1,25-dihydroxy vitamin D3 were measured,and the level of lα-hydroxylase protein in the kidney was determined with immunohistochemistry and Western blotting.The histopathologic changes of kidney tissue were observed under light microscope and the changes of the proximal tubular epithelial cell were observed under electron microscope.Results Compared with SO group,the levels of serum amylase,serum urea nitrogen,and serum creatinine were higher in SAP group,but the levels of serum calcium and 1,25-dihydroxy vitamin D3 decreased at 3,6,and 12 h,and the renal level of 1 α-hydroxylase also decreased at 3,6,and 12 h after modeling.In SAP group,the levels of serum calcium,serum 1,25-dihydroxy vitamin D3 and the renal level of 1 α-hydroxylase gradually decreased,and the renal level of 1 α-hydroxylase and the level of serum 1,25-dihydroxy vitamin D3 had positive correlation at 3 h,6 h,and 12 h (r =0.93,P ＜0.01; r=0.951,P ＜0.01; r =0.92,P ＜0.01; r =0.878,P ＜0.01),and the renal level of 1α-hydroxylase and the level of serum calcium had positive correlation at 3 h,6 h,and 12 h (r =0.975,P ＜0.01; r=0.946,P＜0.01; r=0.747,P＜0.01).Conclusions Intheearly course of SAP,the lowered activity of 1 α-hydroxylase may play an important role in the development of hypocalcemia.

Objective To examine the expression of scinderin in primary hepatocellular carcinoma (HCC) and its paired portal vein tumor thrombus (PVTT) tissues; and to explore its role in the development of HCC and its relationship with prognosis of HCC.Methods Immunohistochemistry was used to detect the expressions of scinderin in tumor-adjacent normal liver tissues,HCC tissues and PVTT tissues from 33 patients.Results The positive expression rates of scinderin in tumor-adjacent normal tissues,HCC tissues and PVTT tissues were 69.7％ (23/33),45.5％ (15/33) and 24.2％ (8/33) respectively.A significantly lower scinderin expression was found in HCC tissues when compared with tumor-adjacent normal tissues (P ＜ 0.05).Also,the expression of scinderin in PVTT tissues was significantly lower than in HCC tissues (P ＜ 0.05).The expression of scinderin in HCC tissues significantly correlated with tumor size,absence of tumor capsule and serum AFP (P ＜0.05).The recurrence-free survival (RFS) and overall survival (OS) of Scinderin-positive patients were significantly longer than Scinderin-negative patients (P ＜ 0.05).Multivariate analysis revealed scinderin expression level to be an independent risk factor affecting RFS and OS after curative resection.Conclusions Scinderin was down-regulated in HCC tissues and PVTT tissues when compared with its paired tumor-adjacent normal liver tissues.The expression level of scinderin correlated with HCC recurrence and prognosis.Scinderin can be used as an indicator of prognosis of HCC patients with PVTT.
