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 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.

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.

Objective To observe the change of the serum trough concentration and its pharmacokinetics of vancomycin in patients with severe acute pancreatitis (SAP), and to analyze the factors influencing vancomycin concentration. Methods A retrospective analysis was conducted. Steady-state trough concentrations of vancomycin from patients (18-80 years old) with SAP concomitantly with G+ infection admitted to Intensive Care Unit (ICU) of Ruijin Hospital Affiliated to Shanghai Jiaotong University School of Medicine from January 2010 to December 2016 were enrolled. According to the usage time of vancomycin, the patients with SAP were divided into early group (onset within 21 days), middle group (onset between 21-28 days) and late group (onset over 28 days). The gender, age, body weight, clinical diagnosis, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ ) score, renal function, and the pharmacokinetic parameters were recorded. Influencing factors of vancomycin was analyzed by multiple linear regression and stepwise regression. Results Fifty-eight patients were enrolled who contained 134 times trough concentrations of vancomycin. There were 41 patients enrolled and 61 times of trough concentrations in the early group, 24 patients enrolled and 33 times of trough concentrations in the middle group, and 28 patients enrolled and 40 times of trough concentrations in the late group. There was no significant difference in gender, age, body weight, serum creatinine, creatinine clearance (CCr), albumin, APACHE Ⅱ score among the three groups. There was significantly difference in the duration from the onset time to vancomycin administration between early, middle groups and late group (days:15.9±3.2, 23.3±2.2 vs. 35.0±6.7, both P < 0.05). The positive liquid balance in early group was lower than that of late group (mL: 1565.2±3132.1 vs. 3675.1±3411.5, P < 0.01), while it was increased in the middle group as compared with that of late group (mL: 5078.7±3892.4 vs. 3675.1±3411.5, P < 0.05). The average daily dose of vancomycin in the early, middle and late groups were (14.7±5.0), (15.0±2.8), (17.0±4.2) mg/kg, respectively, and there was no significant difference (P > 0.05). Compared with the standard concentration (15 mg/L) of vancomycin, the serum trough concentration of vancomycin was significantly reduced in SAP patients [(7.5±4.3) mg/L, P < 0.01]. Apparent volume of distribution (Vd) was (72.4±15.4) L, and clearance rate (CL) was (9.0±2.8) L/h. According to the Bayesian, the serum trough concentration of vancomycin was significantly reduced in early group and middle group compared with late group (mg/L: 5.0±2.1, 7.3±2.5 vs. 11.5±5.1, both P < 0.01), CL was significantly increased (L/h: 10.5±3.0, 8.1±1.9 vs. 7.4±1.9, both P < 0.05), and Vd was significantly increased in early group compared with late group (L: 73.7±15.5 vs. 71.0±12.6, P < 0.05). It was shown by multiple linear regression analysis that there was strong relationship between serum trough concentration and the serum creatinine, CCr, average daily dose and the starting time of vancomycin treatment (r value were 0.449, -0.318, 0.373, 0.763, respectively, all P < 0.05). Conclusions The serum trough concentration of vancomycin was significantly reduced in SAP patients. And the earlier usage of vancomycin, the lower of the trough concentration is. Therefore, higher dosage regimen was needed to ensure the clinical effect, and reduce the bacterial resistance.

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.

Objective To observe the clinical features and prognosis of endogenous bacterial endophthalmitis (EBE).Methods Ten eyes of 10 patients diagnosed with unilateral EBE were retrospectively reviewed,including 7 males and 3 females.The mean age was 57.6± 10.8 years old.Eight patients were with diabetes and 7 of them were diagnosed over 5 years.There were 3 patients with hepatocirrhosis,1 patient with hypertension,and 1 patient with coronary disease.Nine cases had infectious diseases,including liver abscess (7 cases),pulmonary infection (3 cases),erysipelas (1 case) and perianal abscess (1 case).Seven cases had fever history.Culture and drug sensitive tests for aerobic bacteria,anaerobic bacteria and fungal were performed for 9 eyes using vitreous samples from the procedures of vitrectomy and/or intravitreal injection.All patients were treated with broad-spectrum antibiotics and adjusted for drug use according to microbiological culture and drug sensitivity test results.After the diagnosis was established,vitrectomy combined with lens removal was performed in 5 hours (3 eyes) and 24 hours (5 eyes);Vitreous tamponade of C3F8 (1 eye) and silicone oil (7 eyes) was used;At the end of the operation,0.1 ml vancomycin (1 mg) and 0.1 ml ceftazidime (1 mg) were injected into the vitreous cavity.One eye received intravitreal injection of 0.1 ml vancomycin (1 mg) and 0.1 ml ceftazidime (mg),one eye received evisceration.During the follow up period from 6 to 24 months,visual function,slit lamp and fundus examinations were performed at each office visit.Results All patients complained of blurred vision and 5 patients had ocular pain.The visual acuity was no light perception (3 eyes),light perception (5 eyes);hand motion (1 eye) and 0.1 (1 eye).Corneal edema was found in all 10 eyes;hypopyon in 8 eyes;diffuse vitreous opacity in 10 eyes,including 3 eyes with retinal detachment.For 8 eyes treated by vitrectomy and intravitreal injection,1 eye was eviscerated due to uncontrolled inflammation.The eye treated with intravitreal injection was enucleated for its uncontrolled inflammation.For 9 eyes received vitreous culture and drug testing,8 eyes (88.9％) had positive results,including 5 eyes with Klebsiellar pneumonia,and 1 eye with Staphylococcus aureus,or Streptococcus agalactiae or Enterococcus faecalis respectively.At last office visit,2 eyes were with no light perception;4 eyes were with hand motion;and 1 eye with visual acuity of 0.1.Conclusions Most of the patients with endogenous bacterial endophthalmitis have systemic predisposing factors.Klebsiella pneumoniae is the leading cause of ocular EBE.Vitrectomy combined with intravitreal injection of antibiotics showed efficacy in treating EBE.

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.
