Objective To study the expression of estrogen receptor beta (ER ?) in the hypothalamic paraventricular nucleus (PVN) of maternal mice during pregnancy and lactation. Methods Nickel ammonium sulfate intensified immunocytochemical method was employed to investigate the expression of ER ? in the postnatal developing PVN of female mice. Results ER ? immunopositive materials were predominantly localized in the magnocellular division of PVN, and sparse positive cells were found in the parvocellular division. Most of the positive materials were found in the whole cell nuclei, but no obvious cytoplasma or process immunopositive cells were detected. In the pregnant female brain, generally, the ER ? level was lower. The lowest levels of expression were found at mid pregnancy, and then peaked at peripartum (from gestational days 18 to postpartum day 1), followed by another decrease to normal adult level from postpartum day 4. Conclusion The above results suggest that during pregnancy and lactation, ER ? may be predominantly involved in the PVN regulation of parturitional process.

Objective To investigate platelet counts and acute obstructive suppurative cholangitis correlation analysis and possible influential factors.Methods Data of 117 patients from October 2012 to October 2015 treated in our hospital,of whom 57 with acute obstructive suppurative cholangitis and 60 with common acute cholangitis were analyzed retrospectively to explore whether there was a correlation between thrombocytopenia (100 × 109/L) and AOSC,then experimental and control groups were established according to thrombocytopenia in the AOSC patients.The patient's age,sex,previous biliary surgery,white blood cells(WBC) count after admission within 6h,the percentage of neutrophils (NEU%),calcitonin (PCT) were retrospectively analyzed to further explore the influence factors of thrombocytopenia in AOSC patients.Results By comparison with the common acute cholangitis group,thrombocytopenia in AOSC group had obvious difference (P =0.01).In experimental group,NEU%,PCT had statistical difference compared with those in control group (P < 0.05),and the patient's age,sex,previous biliary surgery,white blood cells(WBC) after admission within 6h count had no statistical significance.The logistic multivariate regression analysis showed that,NEU%,PCT were the independent predictors.Conclusion Correlated with AOSC,thrombocytopenia can be valued as indicators of the severity of acute cholangitis.In AOSC patients,NEU%,PCT were independent predictors of thrombocytopenia.

To study the peptidergic innervation in cardiac adenocarcinoma, immunohistochemistry method was employed to examine the distribution of ten kinds of neuropeptide immuno reactive nerve fibers in human cardiac adenocarcinoma, which was surgically obtained, and their relationship with tumor cells. Substantial amount of many kinds of neuropeptides including GAL, Dyn, NPY immuno reactive nerve fibers were observed in the tumor. Most of them were closely in contact with tumor cells. It is possible that there is peptidergic innervation in cardiac adenocarcinoma.

Objective To observe the effect of serum containing Qingluo Tongbi Granula (QTG) on proliferation of fibroblast-like synoviocytes(FLS) and receptor activator of nuclear factor-?B ligand (RANKL) expression in FLS from patients with rheumatoid arthritis.Methods Synovial specimens obtained from the joint of patients were minced into small pieces for the culture of FLS.The morphological features of FLS subcultrued for 3~5 generations were observed under inverted microscope and electron microscope.The effect of QTG-containing serum on the proliferation of FLS was examined by MTT assay.The expression of RANKL in FLS was assessed by RT-PCR.Results After cocultured by serum containing large-dose QTG for 72 hours,proliferation of FLS and expression of RANKL were inhibited.Conclusion QTG can inhibit FLS proliferation,and reduce the expression of RANKL,which may be one of the therapeutic mechanisms of QTG for rheumatoid arthritis.

This study aims to compare the urate-lowering response rate of febuxostat and allopurinol in gout patient using a model-based meta-analysis. The literature search identified 22 clinical trials of gout with a total of 43 unique treatment arms that met our inclusion criteria, and a total of 6 365 gout patients were included in the study. The response rates of allopuriol and febuxostat were characterized by Tmax model and Emax model respectively, and the effect of baseline serum uric acid (sUA) and patient type on the drug effect was tested. The results showed that allopurinol can reach an average maximum response rate of 50.8% while febuxostat can reach a 100% response rate within a very short time, and the ED50 was 34.3 mg. Covariate analysis revealed that baseline sUA has a negative effect on response rate of allopurinol, and a positive effect on the predicted ED50 of febuxostat. For patients who had shown inadequate response to prior allopurinol treatment, the average response rate was about half that of the allopurinol responder patients.

Objective To measure the expression of granulocyte colony-stimulating factor receptor (G-CSFR) in human melanocytes and to evaluate the biologic effect of recombinant human granulocyte colony-stimulating factor (rhG-CSF) on human melanocytes.Methods Melanocytes were obtained from circumcision specimens of healthy males,and neutrophils were isolated from heparin-andcoagulated peripheral blood of healthy human followed by a primary culture.Then,the melanocytes in third passage were cultured with or without the presence of various concentrations (200,400,600,800 μg/L) of rhG-CSF for 72 hours.The growth and morphology of melanocytes were observed.Flow cytometry was performed to detect the expression of G-CSFR in untreated human melanocytes,neutrophils and erythroleukemia cells (HEL 92.1.7).Western blot and reverse transcription PCR (RT-PCR) were carried out to measure the expression of G-CSFR protein and mRNA respectively in the neutrophils,HEL 92.1.7 cells,treated or untreated human melanocytes.Methyl thiazolyl tetrazolium (MTT) assay was performed to evaluate the proliferation,and dopa-oxidation assay to estimate the tyrosinase activity,of treated melanocytes.Results The expression rate of G-CSFR was 76.81% ± 10.70% in human melanocytes,significantly higher than that in the HEL 92.1.7 cells (2.53% ± 1.54%,P < 0.01 ),but lower than that in the neutrophils (85.76% ± 15.71%,P < 0.05).Both G-CSFR protein and mRNA were expressed in melanocytes,and there was no significant differences in the expression level of G-CSFR protein and mRNA among melanocytes treated with different concentrations of rhG-CSF (both P > 0.05).The expression levels of G-CSFR protein and mRNA in the melanecytes were significantly higher than those in the HEL 92.1.7 cells (both P < 0.01 ),but lower than those in the neutrophils (P < 0.05 or < 0.01 ).rhG-CSF at 200-800 μg/L displayed a significantly promotive effect on the proliferation of melanocytes (P < 0.01 or < 0.05 ),and the effect was in a dose-dependent manner when rhG-CSF ranged from 200 to 600 μg/L (P < 0.01 ).The rhG-CSF at 600 μg/L and 12-O-tetradecanoyl-phorbol-13-acetate (TPA) at 20 μg/L showed an equivalent effect on the proliferation of melanocytes (164.04% ± 13.0% vs.165.62% ± 10.6%,P > 0.05).However,rhG-CSF from 200 to 800 μg/L had no significant impact on the tyrosinase activity of melanocytes (all P > 0.05 ).Conclusions G-CSFR is expressed in human melanocytes. rhG-CSF can promote the proliferation of cultured human melanocytes,but has no obvious influence on the tyrosinase activity of melanocytes.
