Juvenile granulose cell tumor is one of the rare sex cord stromal tumors of the ovary.This review summarizes the new progress in the genetic studies of the disease.

The influence of Chang-Bai Xin kui(长白新圭) on the acid ?-naPhthyl acetate esterase(ANAE) positive lymphocytes was studied by using ANAE as a cytochemical marker.S180 cells ef ascites tumor were inoculated into the mice in experimental and control group. 3 days later, 0.8mg/0.2ml of Chang-Bai Xin Kni was injected peritoneally into the mice in experimental group everyday in 7 days. Eaeh of the two groups has its own self control.The experimental results show that there is no significant differences in total numbar of ANAE positive lymphoctes between the two groups and all self-controls.But after 7 days of injecting the drug, the granular pattern and scattered granular pattern of lymphoctes were increased significantly(P

ObjectiveTo investigate whether aldosterone infusion induces glomerular or podocyte injury in rats and to evaluate the effects of eplerenoen (EPL), andodipine (CCB) and telmisartan (ARB) on aldosterone- induced injury. MethodsThirty male Sprague-Dawley rats were divided into 5 groups: control, subcutaneous infusion of aldosterone (1.5 μg/h, ALD group) and aldosterone infusion plus eplerenone (100 mg·kg-1·d-1, EPL group), amlodipine(10 nag·kg-1·d-1 CCB group), telmisartan (3 mg·kg-1·d-1, ARB group), respectively. Systolic blood pressure(SBP) and urinary albumin excretion ratio(UAER) were measured at day 0, 7, 14, 21, 28. Blood samples were harvested to detect plasma angiotensin Ⅱ, plasma aldosterone, serum sodium, serum potassium and serum creatinine at day 28. Glomerular damge was quantified by morphological glomerular injury score (GIS). Immunohistochemistry and RT-PCR were performed to evaluate podocyte lesion, and apoptosis ratio of pedocyte (ARP) in a glomerular cross section was analyzed by TUNEL. ResultsALD infusion progressively increased SBP and UAER compared with CTL (P＜0.01). SBP was significantly reduced in EPL, CCB or ARB-treated animals, meanwhile, UAER was decreased in EPL and ARB group, but not in CCB group. The ALD-infused rats exibited hypernatremia and hypopotassaemia, which were blocked by EPL adminstration but not by CCB or ARB treatment. ARB group had a significant increase in plasma angiotensin Ⅱ compared with ALD, CCB and EPL groups(P＜0.01). The ALD-infused animals developed hyperaldosteronemia compared with CTL, but with no difference of plasma aldosterone among ALD, EPL, CCB and ARB-treated rats. Treatment with EPL prevented an increase of GIS and ARP compared with CCB and ARB (P＜0.05, P＜0.01). Protein and mRNA expression of nephfin was up-regulated in ALD group (P＜ 0.01), but was significantly prevented by EPL treatment(P＜0.01), whereas CCB and ARB therapy had no such effect. Conclusion ALD infusion significantly induces glomerular and pedocyte injury which is blocked by EPL but not by CCB or ARB independently on systemic hemodynamics.

Objective To investigate and evaluate the comparison results of five items of hepatitis B in ELISA by using water bath box and rapid incubation .Methods 92 patients with hepatitis B in our hospital from June 2012 to June 2013 were randomly se‐lected and 184 cases of healthy physical examination were randomly selected as the controls .The water bath and rapid incubation were adopted to conduct ELISA for simultaneously detecting 5 items of hepatitis B in samples .Results The results of two groups had higher positive coincidence rate .The average OD value of specimens in the water bath was higher .But the specimen S/CO value in the fast average incubation was higher ,its co value was higher than that of the water bath .Conclusion The rapid incubation can be introduced for improving the work efficiency in the daily work ,but the specimen with weak reactiveresult needs to be re‐de‐tected by using the water bath and making records .The fast incubation device is best for only use of the HBsAg reaction ,because the other four reaction process time is shorter ,and there are some non‐conformity results .

Objective Both right and left ventricular function should be taken into account in the assessment of anthracycline (ATC)-induced cardiotoxicity.The aim of this study was to assess the subclinical dysfunction of right cardiac system in patients with newly diagnosed lymphoma who received ATC treatment by echocardiography.Methods A total of 74 patients with lymphoma who received ATC treatment were enrolled.Each patient underwent transthoracic echocardiographic examination before chemotherapy as well as after two,four and six cycles of ATC remedy.Right atrial (RA) and right ventricular (RV) end-diastolic area (EDA) and end-systolic area (ESA) were calculated.RV end-diastolic volume (EDV) and end-systolic volume (ESV),as well as RV ejection fraction (EF) were measured simultaneously.Tissue Doppler imaging (TDI) measurements of systolic and early or late diastolic myocardial velocities of RV free wall at tricuspid annuals were also analyzed.Two-dimensional speckle tracking echocardiography (2DSTE) was conducted to evaluate RV free wall strain along with strain rate.Results None of the echocardiographic parameters showed significant alteration after two and four cycles of chemotherapy compared with those at baseline (P＞0.05).At the end of the therapy (i.e.after six cycles of ATC treatment),there was still no statistical difference on TDI data aswell as 2DSTE measurements (P＞0.05).An unexpected finding was that the RAEDA((6.6±1.9) cm2 vs (7.7±2.4) cm2) and RAESA ((8.8±2.5) cm2 vs (10.8±2.8) cm2) revealed obvious dilatation after six cures of the regimen compared with those at baseline (P＜0.01).Similar morphologic characteristics displayed on the RVEDA ((14.1 ±3.4) cm2 vs (16.2±3.7) cm2) and RVESA ((7.9±1.9) cm2 vs (9.0±2.2) cm2) (P＜0.01)simultaneously.Furthermore,RVEDV ((29.8±10.5) ml vs (37.0±12.7) ml) and RVESV ((12.7±4.4) ml vs (15.0±5.2) ml),as well as RVEF ((59.4±5.8)％ vs (56.4±5.8)％),in patients with lymphoma presented statistically significant difference between basic state and the level after six cycles of chemotherapy (P＜0.01).Meanwhile,no marked change was detected on left ventricular ejection fraction(LVEF) throughout the follow-up period (P＞0.05).Conclusions Echocardiography can be used easily and noninvasively to assess right cardiac system subclinical dysfunction.ATC-induced cardiotoxicity of right cardiac system is firstly manifested as morphological changes than the measurements with novel echocardiographic techniques.In addition,RVEF expresses as a valuable parameter for assessing subtle RV impaired performance in patients with lymphoma received ATC therapy.

Objective To explore the efficacy and adverse reaction of nedaplatin (NDP)+gemcitabine (GEM)and cisplatin (DDP)+GEM for advanced lung squamous cell carcinoma.Methods A total of 1 01 cases advanced untreated patients from September 201 2 to December 201 3 were randomly divided into 2 groups using random number table method:69 patients in the observation group accepted NDP+GEM treatment and 32 patients in the control group received DDP +GEMtreatment.The objective response rate (RR),disease control rate (DCR ) and progression-free survival (PFS ) and adverse reaction were collected and evaluated. Results RR was 28.6%(1 8/63)in the observation group and 1 5.6%(5/32)in the control group,DCR was 81 .0%(51/63)in the observation group and 68.8%(22/32)in the control group (χ2 =1 .36,P=0.24;χ2 =1 .67,P=0.20).The median PFS was 4.52 months and 4.01 months in the observation group and control group (χ2 =0.09,P=0.73).The major adverse reaction was myelosuppression in both groups (33.3% vs.37.5%,χ2 =0.1 7,P=0.68).The incidence ofⅢ-Ⅳ grade nausea and vomiting was lower in the observation group, compared with the control group (1 4.5%vs.56.3%,χ2 =1 9.02,P=0.05).Conclusion NDP combined with GEM in advanced lung squamous cell carcinoma of the first-line treatment has equivalent efficacy to DDP+GEM, with lower incidence of adverse reaction,which is worthy of further dissemination of research.

Objective This study was designed to observe the impact of cigarette cessation on anxiety and depression in patients with coronary heart disease (CHD).Methods A total of 690 cigarette smoking patients with CHD identified by coronary angiography (CAG) were included and analyzed in the study.The mental state were scored with Hamilton anxiety (HAMA) and depression (HAMD) scale both on admission and at 6-month follow-up.The patients were divided into two groups based on the cigarette cessation.The score of mental state between the two groups were compared.The patients were treated with percutaneous coronary intervention (PCI),coronary artery bypass grafting (CABG),or medicine therapy (MT).Results The clinic data and score of mental state were similar at the time of admission (HAMA:10.66±5.53 vs 11.09 ±5.61,P =0.311;HAMD:29.81 ± 10.13 vs 28.94 ± 10.22,P =0.266 4) between the two groups.After 6 months,the proportions of subjects in smoking cession group with anxiety (24.2％ vs 32.3％,P ＜0.05),depression (18.0％ vs 27.5％,P ＜0.05),and anxiety and depression (7.0％ vs 16.2％,P ＜0.001) decreased significantly compared with those in smoking group irrespective of the treatment strategy.Both the HAMA and HAMD scores were lower in smoking cessation group (HAMA:9.83±3.40;HAMD:24.91 ±7.90) than in smoking group (HAMA:10.98 ±4.87;HAMD:27.70 ± 11.16) (all P ＜ 0.001).Conclusions Smoking cessation is good for the relief of anxiety and depression in CHD patient.

Objective To evaluate the prophylactic effects of propranolol, propranolol plus endoscopic variceal ligation (EVL) and propranolol plus endoscopic sclerotherapy (EVS), and to determine the most effective combination for secondary prevention of esophageal variceal bleeding.Methods After hemostasis, a total of 78 patients with esophageal variceal bleeding were randomly assigned to receive propranolol (propranolol group), propranolol plus EVL (ligation group) or propranolol plus sclerotherapy (EVS group), with 26 in each group.All patients were followed up for 12 months, and the rates of variceal re-bleeding, mortality, portal hypertensive gastropathy (PHG), re-occurrence of esophageal varices and formation of gastric fundus varices were compared among different groups.Results During the 12-month follow-up, the rate of re-bleeding in EVL group (30.77%) was significantly lower than those of the EVS group (42.31%) or propranolol group (53.85%) (P<0.05).The occurrence of PHG and fundal varices in patients of EVL group was similar to that of propranolol group, which were both lower than that of EVS group (P<0.05), but the re-occurrence of esophageal varices in EVL group was significantly higher than that of EVS group (P<0.05).Conclusion EVL plus propranolol might be the most effective therapy for secondary prophylaxis of esophageal variceal bleeding.

Objective To explore the molecular mechanism of BRAFV600E inducing chromosome instability in Sbcl2 and SK-MEL31 melanoma cells.Methods The endogenous Mps1 in stable Sbcl2-and SK-MEL31-B-RafV600E expression cells were depleted by siRNA approach.To test the effect of B-RafV600E on the centrosome amplification and the formation of multipolar spindles,cells at S-phase with HU-treatment were arrested and then the centrosomes and mitotic spindles structure were detected through immunofluoresence.Results The percentage of B-RafV600E expressing Sbcl2 and SK-MEL31 cells (Sbcl2-B-RafV600E and SKMEL31-B-RafV600E) with centrosome amplification and multipolar spindle was reduced from 36 ％ to 6 ％ when Mps1 was absent.Conclusion B-RafV600E leads to centrosome amplification and multipolar spindle through Mps1,thus results in chromosome instability in Sbcl2 and SK-MEL31 melanoma cells.
