Objective To compare the efficacy of amisulpride and other SGAs in treating the negative symptoms of Schizophrenia.Methods The randomized controlled trials (RCTs) about Schizophrenia treated with amisulpride and other SGAs from Jan 1995 to Mar 2013 were searched in The Pubmed,EMbase,Cochrane Library,WanFang Data,CNKI and VIP.Two reviewers independently screened the literatures,extracted the data,and evaluated the methodological quality.Than meta-analyses were conducted by using RevMan 5.1 and Stata 12.0 software.Results The totall3 RCTs were included.Among the 1814 patients involved.The results of meta-analyses showed that the score of PANSS-N was no significant differences between two groups (MD =-0.33,95％ CI:(-0.87,0.21),Z =1.20,P =0.23) ; and the score of SANS was no significant differences between two groups (MD =-0.21,95％ CI:(-1.51,1.50),Z =0.31,P =0.76).The side effects were more in other SGAs group than those in amisulpride group.Conclusion Amisulpride is as effective as other SGAs for the treatment of schizophrenia with predominantly negative symptoms,and it has more advantage than other SGAs in safety.

Objective To determine the effect of hypothermia on gene transcription and protein expression of calpain after traumatic brain injury (TBI). Methods Twenty-seven rats were randomly divided into three groups, ie, normal control group, normothermia TBI group and hypothermia TBI group. All rats with TBI were suffered from a lateral fluid percussion injury (FPI) at the right parietal lobe. Hy-pothermia intervention [rectal temperature for (32 ± 0.5) ℃] was performed for four hours immediately after TBI in hypothermia TBI group. Fluorescence PCR and Western blot were utilized to semi-quantify gene transcription and protein expression of ealpain and immunofluorescence used to observe protein dis-tribution of Calpain. Results Compared with normothermia TBi group and normal control group, hypo-thermia TBI group showed increased calpain gene transcription at 12 and 24 hours respectively after FPI (P <0.05). However, the increase of ealpain protein expression in hypothermia TBI group was inhibited more significantly by hypothermia at 6,12,24 and 72 hours after TBI, compared with normothermia TBI group (P < 0.05). Conclusion Neuroproteetion of hypothermia after TBI may somewhat be related to the decrease of calpain protein expression after its gene transcription.

Objective To investigate the social cognition and its correlation with social function for attenuated psychosis syndrome (APS). Methods From August, 2014 to December, 2015, 39 patients with APS were recruited as research group. Another 40 normal healthy persons with similar gender, ages, and education levels were selected as control group. The Faux Pas Recognition Test (FPR) and Yoni Task Test were used to evaluate the social cognition, and Social Disability Screening Schedule (SDSS) was used to evaluate the social function. The correlation between FPR, Yoni Task Test and SDSS in the research group was analyzed. Results In FPR test, the faux pas questions score, control questions score and total score of FPR were significantly lower in the research group than in the normal control group (t>2.378, P<0.01). In Yoni Task Test, the cognitive theory of mind total score (Cog), cognitive theory of mind first-level score (Cog1) and cog-nitive theory of mind second-level score (Cog2), and affective theory of mind total score (Aff), affective theory of mind first-level score (Aff1) and affective theory of mind second-level score (Aff2) were significantly lower in the research group than in the normal control group (t>2.341, P<0.01). There was no significant difference in control theory of mind total score (Phy), control theory of mind first-level score (Phy1) and control theory of mind second-level score (Phy2) between two groups (t<1.430, P>0.05). The SDSS total score was signifi-cantly higher in the research group than in the normal control group (t=13.032, P<0.001). In the research group, FPR's faux pas questions score and FPR's total score were negatively correlated with SDSS score (r>0.473, P<0.01); in Yoni task test, Cog's total score and factor scores, Aff's total score and factor scores were negatively correlated with SDSS score (r>0.448, P<0.01). Conclusion Social cognition func-tion in APS is impaired. It is associated with social dysfunction in APS.

Objective To explore the imaging features of papillary thyroid microcarcinoma(PTMC) with real time contrast-enhanced ultrasound.Methods One hundredand forty-three cases with 149 thyroid nodules(no diffuse lession) were divided into two groups according to the diameter size(group 1,＜0.5 cm;group 2,0.5-1.0 cm) and examined by contrast-enhanced ultrasound during preoperation.Pathology was followed up as golden diagnosis criteria.Results Seventy-five benign tumors and 74 PTMC were confirmed by pathology.There were significant differences in echoes homogeneity between benign and malignant tumors in group 2(W =1 029.5,Z =-5.524,P =0.000) but no in group 1(W =933.0,Z =-1.738,P =0.082).And nonhomogeneous enhancement were showed in most PTMC in group 2.But most PTMC showed homogeneous enhancement in group 1.Conclusions Contrast-enhanced ultrasound is valuable in diagnosis of PTMC with the diameter size of 0.5-1.0 cm.

OBJECTIVETo investigate the effects of different concentrations of lipopolysaccharide (LPS), tumor necrosis factor α (TNFα), interleukin-6 (IL-6), dexamethasone (Dex), and insulin on the mRNA and protein expressions of GPR54 in the MCF7 cell line in vitro.

METHODSMCF7 breasr cancer cells were cultured and treated with different concentrations of LPS (10 and 20 µg/ml), TNFα (20 and 100 ng/ml), IL-6 (10 and 20 ng/ml), Dex (10(-6) and 10(-7) mol/L), and insulin (0.01 and 0.1 IU/L). Those treated with culture fluid only served as controls. The mRNA and protein expressions of GPR54 were measured by real-time PCR and Western blot, respectively, after 6, 24, 48, and 72 hours of treatment.

RESULTSCompared with the blank con- trol, LPS (10 and 20 µg/ml), TNFα (20 and 100 ng/ml), IL-6 (10 and 20 ng/ml), Dex (10(-6) and 10(-7) mol/L), and insulin (0.01 and 0.1 IU/L) significantly increased the expressions of GPR54 mRNA (P < 0.05) and protein (P < 0.05).

CONCLUSIONLPS, TNFα, IL-6, Dex, and insulin evidently increase the expression of GPR54 in the MCF7 cell line, indicating their influence on the function of gonads by regulating the GPR54 level.

Pulsatile gonadotropin-releasing hormone (GnRH) may induce spermatogenesis in most patients with congenital hypogonadotropic hypogonadism (CHH) by stimulating gonadotropin production, while the predictors for a pituitary response to pulsatile GnRH therapy were rarely investigated. Therefore, the aim of our study is to investigate predictors of the pituitary response to pulsatile GnRH therapy. This retrospective cohort study included 82 CHH patients who received subcutaneous pulsatile GnRH therapy for at least 1 month. Patients were categorized into poor or normal luteinizing hormone (LH) response subgroups according to their LH level (LH <2 IU l-1 or LH ≥2 IU l-1) 1 month into pulsatile GnRH therapy. Gonadotropin and testosterone levels, testicular size, and sperm count were compared between the two subgroups before and after GnRH therapy. Among all patients, LH increased from 0.4 ± 0.5 IU l-1 to 7.5 ± 4.4 IU l-1 and follicle-stimulating hormone (FSH) increased from 1.1 ± 0.9 IU l-1 to 8.8 ± 5.3 IU l-1. A Cox regression analysis showed that basal testosterone level (β = 0.252, P = 0.029) and triptorelin-stimulated FSH60min(β = 0.518, P = 0.01) were two favorable predictors for pituitary response to GnRH therapy. Nine patients (9/82, 11.0%) with low LH response to GnRH therapy were classified into the poor LH response subgroup. After pulsatile GnRH therapy, total serum testosterone level was 39 ± 28 ng dl-1 versus 248 ± 158 ng dl-1 (P = 0.001), and testicular size was 4.0 ± 3.1 ml versus 7.9 ± 4.5 ml (P = 0.005) in the poor and normal LH response subgroups, respectively. It is concluded that higher levels of triptorelin-stimulated FSH60minand basal total serum testosterone are favorable predictors of pituitary LH response to GnRH therapy.

Both pulsatile gonadotropin-releasing hormone (GnRH) infusion and combined gonadotropin therapy (human chorionic gonadotropin and human menopausal gonadotropin [HCG/HMG]) are effective to induce spermatogenesis in male patients with congenital hypogonadotropic hypogonadism (CHH). However, evidence is lacking as to which treatment strategy is better. This retrospective cohort study included 202 patients with CHH: twenty had received pulsatile GnRH and 182 had received HCG/HMG. Patients had received therapy for at least 12 months. The total follow-up time was 15.6 ± 5.0 months (range: 12-27 months) for the GnRH group and 28.7 ± 13.0 months (range: 12-66 months) for the HCG/HMG group. The median time to first sperm appearance was 6 months (95% confidence interval [CI]: 1.6-10.4) in the GnRH group versus 18 months (95% CI: 16.4-20.0) in the HCG/HMG group (P < 0.001). The median time to achieve sperm concentrations ≥5 × 10 6 ml-1 was 14 months (95% CI: 5.8-22.2) in the GnRH group versus 27 months (95% CI: 18.9-35.1) in the HCG/HMG group (P < 0.001), and the median time to concentrations ≥10 × 10 6 ml-1 was 18 months (95% CI: 10.0-26.0) in the GnRH group versus 39 months (95% CI unknown) in the HCG/HMG group. Compared to the GnRH group, the HCG/HMG group required longer treatment periods to achieve testicular sizes of ≥4 ml, ≥8 ml, ≥12 ml, and ≥16 ml. Sperm motility (a + b + c percentage) evaluated in semen samples with concentrations >1 × 10 6 ml-1 was 43.7% ± 20.4% (16 samples) in the GnRH group versus 43.2% ± 18.1% (153 samples) in the HCG/HMG group (P = 0.921). Notably, during follow-up, the GnRH group had lower serum testosterone levels than the HCG/HMG group (8.3 ± 4.6 vs 16.2 ± 8.2 nmol l-1 , P < 0.001). Our study found that pulsatile GnRH therapy was associated with earlier spermatogenesis and larger testicular size compared to combined gonadotropin therapy. Additional prospective randomized studies would be required to confirm these findings.

Objective To evaluate the serum trough concentration and the pharmacokinetics/pharmacodynamics (PK/PD)of vancomycin in patients with severe acute pancreatitis (SAP), and analyze the effect of vancomycin continuous infusion for optimizing the characteristics of its PK/PD.Methods The inhospital patients with SAP received vancomycin treatment and admitted to emergency intensive care unit (EICU) of Ruijin Hospital Affiliated to Shanghai Jiaotong University School of Medicine from January 2011 to December 2016 were enrolled. Steady-state trough concentrations of vancomycin from patients were collected retrospectively. The SAP patients were divided into augmented renal clearance (ARC) and non-ARC groups, as well as systemic inflammatory response syndrome (SIRS) and non-SIRS groups according to the patients with or without symptom above. Adjustments of increased dosage or 24-hour continuous infusion or increase vancomycin dose were made for patients if the steady-state trough concentrations fell below the target level. Steady state trough concentration for vancomycin intermittent infusion or steady state concentration for vancomycin continuous infusion was determined by the fluorescence polarization immunoassay method. PK parameters of vancomycin were calculated using the Bayesian estimator and the area under the serum drug concentration-time curve (AUCc-t), the minimum inhibitory concentration (MIC) and AUCc-t/MIC was recorded and calculated.Results The steady state trough concentration or steady state concentration from 61 patients with SAP were collected with mean steady state trough concentration of vancomycin of (7.7±4.4) mg/L, which was significantly lower than standard concentration (15 mg/L,P < 0.001). Apparent volume of distribution (Vd) and clearance of vancomycin was (1.06±0.26) L/kg and (8.9±2.8) L/h. The serum steady state trough concentration of vancomycin in ARC group (n = 33) was significantly lower than that in non-ARC group (n = 28; mg/L: 6.7±3.5 vs. 8.2±4.1, P < 0.01), clearance was significantly increased (L/h: 9.8±2.9 vs. 7.7±2.2,P < 0.01). Compared with non-SIRS group (n = 31), the serum steady state trough concentration of vancomycin in SIRS group (n= 30) was significantly lowered (mg/L: 6.1±3.2 vs. 13.0±4.2,P < 0.01), and clearance was significantly increased (L/h: 9.4±2.0 vs. 7.1±2.1,P < 0.05). Compared with the only increasing vancomycin dose group (n = 29), vancomycin continuous infusion for 24 hours (n = 21) could significantly reduce daily dosage (mg/kg: 13.6±3.9 vs. 19.1±3.5,P < 0.01), increase the serum trough concentration (mg/L: 18.1±7.0 vs. 12.6±5.3,P < 0.01), and improve the AUCc-t/MIC.Conclusions The serum trough concentration of vancomycin was significantly reduced in SAP patients with ARC. The more serious of the SIRS is, the lower the vancomycin trough concentration is. Vancomycin 24-hour continuous infusion could optimize the PK/PD parameters, decrease the daily dose, increase the clinical effect, and reduce the bacterial resistance.

Objective To investigate the mRNA and protein expressions of Nav 1.1 and Nav 1.2 in hippocampus following traumatic brain injury ( TBI) in rats.Methods After the lateral fluid percussion model was established in adult male Sprague Dawley rats,the rats were sacrificed at 2,12,24 and 72 hours after percussion and collected ipsilateral hippocampus for detecting mRNA and protein expressions of Nav 1.1 and Nav 1.2 by means of fluorescent quantitation RT-PCR,Western blot and immunofluo rescence staining.Results The mRNA expressions of Nav 1.1 and Nav 1.2 were significantly down-regulated (P<0.01) in hippocampus and reached the lowest level at 2 hours following TBI.The protein expression of Nav 1.1 was significantly down-regulated (P<0.01) but recovered near to level of control group at 72 hours after TBI.While there was no statistical difference on protein expression of Nav 1.2 in hippocampus after TBI compared with control group (P>0.05).Conclusion TBI induces significant down-regulated mRNA and protein expressions of Nav 1.1 in the hippocampus,which may be one of molecular mechanisms for functional alternation of sodium channels and excitotoxic action following TBI.
