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 evaluate right ventricular (RV)systolic function in type-2 diabetes mellitus (T2DM)patients.Methods Fifty T2DM patients and fifty normal controls were included in the study and underwent echocardiographic examinations.The following parameters were measured:1 ) Right heart dimensions,pulmonary artery (PA)diameter,pulmonary acceleration time (AT)and PA systolic pressure (PASP);2)RV systolic function:RV fractional area change (RVFAC),tissue Doppler-derived tricuspid lateral annular systolic velocity (S'),tricuspid annular plane systolic excursion (TAPSE),longitudinal strain of six RV segments by 2-dimensional speckle tracking imaging (2D-STI);3 )RV diastolic function:E,A ratio of the tricuspid inflow spectrum (E/A),E,E'(peak early diastolic velocity of the tricuspid annulus) ratio (E/E');4)RV Tei index.Results Statistic analysis showed that T2DM patients had thicker RV walls,wider PAs and shorter AT than the control group (P =0.000,0.001 and 0.000),while their right heart chamber sizes and PASP remained unchanged.Among systolic parameters,absolute values of RV longitudinal strain at the lateral wall-mid (lat-m),septum-mid (sep-m)and septum-basal (sep-b)segments were significantly lower in the diabetic group than the control group (P =0.001 ,0.000 and 0.005),whereas strain of the other three RV segments and RVFAC,TAPSE.S'were not significantly different.Moreover, E/A,E/E'and Tei index were all significantly different between the two groups (P = 0.000,0.000 and 0.006),indicating declined diastolic and general function of RV in the T2DM group.Conclusions RV myocardial strain by 2D-STI is more sensitive in detecting RV systolic dysfunction than TAPSE,S' and RVFAC.Among the six segments of RV walls,lat-m,sep-m and sep-b are better locations for 2D-STI than the other three.

Objective To examine the correlation between end-tidal carbon dioxide (PetCO2) and arterial CO2 (PaCO2) among patients admitted in neurosurgical intensive care unit (NICU) and the factors affecting the PaCO2-PetCO2 [P (a-et) CO2].Methods Thirty-two intubated or cut-trachea patients who presented in the NICU were enrolled.Arterial blood gas test was done at seven every morning,and values of PetCO2 were compared with simultaneously recorded PaCO2.The normal gap of P (a-et) CO2 was defined as-5 mmHg to 5 mmHg.Concordance between PaCO2 and PetCO2 was analyzed using the Bland-Altman plot.Parameters between the normal and high P(a-et) CO2 groups were compared to identify the factors affecting the P(a-et) CO2,including Glasgow Coma Scale(GCS),blood pressure (BP),heart rate (HR),respiration rate (RR),body temperature (BT),and pulse oxygen saturation (SpO2).Results Allvalues of PaCO2 and PetCO2 were in accordance with normal distribution (r =0.668,P ＜ 0.01) and concordance between PaCO2 and PetCO2 was 69.8％.Patients who had high P(aet) CO2 showed lower initial GCS,lower instant GCS,BT,as well as pH and higher actual bicarbonate (AB) and PetCO2 than the patients with normal P (a-et) CO2.Correlation between PaCO2 and PetCO2 rapidly declined when positive end expiratory pressure(PEEP) was greater than 5 mmH2O(r =0.229,P ＜ 0.01).Conclusions PetCO2 correlates well with PaCO2 and appears to be a useful monitor of respiratory function of the patients consecutively.Initial GCS,BT,AB and PEEP have an impact on P(a-et) CO2,so those factors should be considered when attempting to monitor the hyperventilation with PetCO2.

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.

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 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 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.
