Objective To investigate cognitive function and behavior characteristics in the childhood onset schizo?phrenia patients with or without obsessive-compulsive symptoms. Methods One hundred forty-nine schizophrenia chil?dren were recruited and 72 healthy children served as children control group. According to the Schedule for Affective Dis?orders and Schizophrenia for School-Age Children-Present and Lifetime Version (K-SADS-PL), the patients were fur?ther divided into two groups, the children with obsessive-compulsive disorder group (70 cases) and the children without obsessive-compulsive disorder group (79 cases). All the children were retrospectively surveyed and the Achenbach’s Child Behavior Check-list (CBCL) was used to assess their social competence and behavioral characteristics at the age from 6-year-old to 10-year-old. The cognitive function was estimated with WISC, STROOP color and word test, trail making test, visal spatial memory test and maze test. Results Compare to the control group, the CBCL factor scores of behavior problems were higher (P<0.01), social ability factor scores were lower (P<0.05) and all factor scores in the cog?nitive function tests were lower (P<0.05) in the two patients groups. Compare to the patients without obsessive-compul?sive symptoms, the CBCL factor scores of the school situation (P<0.01), splitting force (P<0.01), and physical complaints (P<0.01) were significantly higher and the scores were significantly lower in the test of common sense (P<0.01), wood (P<0.01), STROOP (P<0.01) and BVMT-R (P<0.01) in those with obsessive-compulsive symptoms. Correlation analysis showed that social competence total scores were positively correlated with similarity in the patients with obsessive-com?pulsive symptoms (r=0.31, P<0.01);while behavior problems total scores were negatively correlated with wood (r=-0.31, P<0.01) and patchwork (r=-0.32, P<0.01) in the patients without obsessive-compulsive symptoms. Conclusion The schizophrenia children with obsessive-compulsive symptoms have more behavioral problems in pre-symptom period and their cognitive dysfunction are more severe following onset of the disease. Cognitive function is related to behavioral prob?lems and social competence in the schizophrenia children with or without obsessive-compulsive symptoms .

Objective To study blood lipids levels of patients with ischemic cerebral vascular disease (ICVD).Methods The blood lipids levels were measured in 2886 subjects with ICVD enrolled from 1991 to 2004,in which 1430 subjects from 2000 to 2004 were classified into a sub-group;400 healthy persons receiving physical examination were enrolled as controls.Results The blood TC,TG and LDL-C levels were significantly higher in the sub-group than those in the control group.Both in males and females, the morbidity of abnormal blood lipid metabolism and blood lipids level gradually increased with the age and the lapse of decades.Total cholesterol level of male younger than fifty,averaging (4.43?0.51) mmol/L, increased to (4.96?0.85) mmol/L after fifty years old.The same thing happened to females,from (4.30?0.49) mmol/L to (5.01?0.90) mmol/L.TG and LDL-C increased in patients older than fifty compared with those younger than fifty.In the groups above 50 years old,the blood lipids levels of females were significantly higher than those of males.The morbidity of abnormal blood lipid metabolism of male increased from 24.5% in (1991 to 1994) to 38.1% (2001 to 2004) and of female from 22.3% (1991 to 1994) to 38.5% (2001 to 2004).Conclusions Abnormal blood lipid in Foshan is one of the most important reasons to ICVD.

Objective To investigate the correlation of hepatitis B virus (HBV) markers between umbilical cord blood and maternal serum.Methods A total of 340 HBsAg positive mothers who delivered at the Third People' s Hospital of Changzhou during August 2009 and November 2010 were included in the study.HBV markers in the maternal serum before childbirth and umbilical cord blood after birth were quantitatively detected.The neonates received 3 doses of hepatitis B vaccine and 2 doses of hepatitis B immunoglobulin (HBIG),and followed up for 12 months.Measurement data were expressed as median (M),and Kruskal-Wallis test and Spearman correlation analysis were performed.Results There were 175HBeAg-positive and 165 HBeAg-negative mothers,and a total of 341 infants were delivered.The positive rates of HBsAg,anti-HBs,HBeAg,anti-HBe and anti-HBc in maternal serum were 100.00％,0.0％,51.47％,38.82％ and 99.41％,respectively; while those in umbilical cord bloods were 14.66％,0.59％,26.69％,39.88％ and 95.31％,respectively.HBsAg concentration in maternal serum of HBsAg-positive umbilical cord blood group was higher than that of HBsAg-negative umbilical cord blood group (419.40∶ 387.95,x2 =4.592,P ＜ 0.05) ; while HBsAg concentration in umbilical cord blood of HBeAg-positive maternal serum was higher than that of the HBeAg-negative maternal serum group (0.04 ∶ 0.01,x2 =5.674,P ＜ 0.05).Anti-HBe and anti-HBc in umbilical cord blood were positively correlated with those in maternal serum (r =0.838,0.764,P ＜ 0.01).Seven out of 62 (11.29％) infants were infected with HBV in HBeAg-positive maternal serum group; while no infant infected in HBeAg-negative matemal serum group.Conclusion The higher maternal serum HBsAg concentration,the greater the risk of perinatal transmission,and infants born by HBeAg-positive mothers are of high risk of HBV infection.

Objective To investigate cardiac reserve function and pregnant results of preeclampsia.Methods Pregnant women chosen by randomized table and hospitalized in the department of obstetrics of the first affiliated hospital of Chongqing MedicaI University were involved in this study from January to December,2008.Sixty-nine cases of normal pregnant women were divided into 3 groups:normal group 1(20cases),normal group 2(26 cases)and normal group 3(23 cases).The normal group number 1 to number 3 were paired to gestational hypertension(20 cases),mild preeclampsia(26 cases)and severe preeclampsia (23 cases),respectively.The digital technique of heart sound signal processing WaS used to measure cardiac reserve function parameters including the heart rate(HR),the ratio of the amplitude of the first heart sound to the second heart sound(S1/S2)and the ratio of diastolic to systolic duration(D/S)of pregnant women.The pregnant results were also recorded.Results (1)The ratio of S1/S2 in the group of severe preeclampsia 4.5±3.2 was significantly bigher than the group of gestational hypertension 2.2±1.1 and normal group 32.2±1.1(P＜0.01).The ratio of D/S of the group of severe preeclampsia 1.1±0.3 Was significantly lower than the group of gestational hypertension 1.4±0.3 and normal group 31.4±0.2(P＜0.01).(2)All cases of the normal group number 1 to number 3 and the group of gestational hypertension were found the ratio of D/S≥1.00,whereas 1 case(1/26,4%)of the group of mild preeclampsia and 4 cases(4/23.17%)of the group of severe preeclampsia were found the ratio of D/S＜1.00.(3)The two cases of the pregnant wornen(including one woman died of cardiac arrest)with S1/S2＞5.00 and D/S＜1.00,who were in the group of severe preeclampsia,were sent to Intensive Care Unit after delivery.There were 4 cases(4/26,15%)and 6 cages(6/23,26%)of 1 minute Apgar score less than 7,7 cases(7/26,27%)and 6 cases(6/23,26%)sent to neonatal Intensive Care Unit,2 cases(2/26,8%)and 4 cases(4/23,17%)of neonatal death in the group of mild preeclampsia and in the group of severe preeclampsia,respectively.All newborns in the normal group number 1 to number 3 and the group of gestational hypertension were normal.Conclusions The cardiac reserve function of a pregnant woman with preeelampsia is decreased with the severity of preeclampsia and the parturient and neonatal results get worse.The distal technique of heart sound signal processing is a safe,harmless,simple and effective tool to measure cardiac reserve funotion of preeclampsia,and is worthy of widely used clinically.

OBJECTIVE:To promote the clinical application and improve the curative effect of serum concentration.METHODS:In a retrospective review,the serum drug concentrations of 487 outpatients and inpatients of our hospital treated with 3 kinds of anti-epileptics included valproic acid,phenytoin and carbamazepine were analyzed.RESULTS:Among 487 samples,there were 248 cases(50.92%) whose serum concentration were in normal range,177 cases (36.34%) in low range and 51 cases(10.47%) in high range.Also,there were 11 cases(2.26%) whose serum concentration could not be monitored.The percentage of patients treated with valproic acid,carbamazepine and phenytoin whose serum concentrations in normal range were 48.18%,74.29% and 10.87%.CONCLUSION:The serum concentration monitoring of Anti-epileptic is the important measure which provide the basis for adopting individualized administration and ensures the clinical effect and safety in the medical care.

Hypoxia/ischemia is a common clinical pathophysiological process and cause of death,and it is a common problem in extreme conditions such as high altitude,astronautics and diving.Hamartin is a kind of effective endogenous neuroprotectant and could increase cell tolerance to acute hypoxia or ischemia, thus,is of significance to research.The role of hamartin in hypoxia/ischemia has been a research focus of many scientists.Elucidating the related protective effect and its DNA methylation on hypoxia/ischemia can not only reduce injury,but also lay a basic for further studying the role of hamartin and its DNA methylation in other pathophysiological processes and provide theoretical guidance for the following clinical study.In this paper,we review the structure,mechanism and role of hamartin and the effect of its DNA methylation on hypoxia/ischemia.

Objective To investigate the characteristics and relationship of cognitive function and resting state functional magnetic resonance imaging(fMRI) amplitude of low-frequency fluctuations (ALFF)in childhood and adolescence-first-onset obsessive-compulsive disorder(OCD).Methods Twenty-four childhood and adolescence-first-onset OCD patients (patient group) and thirty-three age/gender/education-matched healthy controls (healthy control group) were enrolled in this study.The participants' cognitive function was tested with trail making test (TMT),symbol coding,Hopkins verbal learning test-revised (HVLT-R),brief visuospatial memory test-revised (BVMT-R),verbal fluency test (VF),digital span test,maze test and Stroop test.Then a resting-state fMRI scan was conducted for each participant.Amplitude of low-frequency fluctuation approach was used to explore the differences of resting-state brain function between patients and controls,and analyze the significant brain regions by adopting t test.The cognitive functions of patients and healthy control group in the significant brain regions were compared by using Pearson correlation analysis.Results The patient group had lower scores than healthy control group in symbol coding,BVMT-R and digital span test,and the differences were statistically significant [(45.24 ± 10.32)scores vs.(56.85 ± 9.57) scores,(21.94 ± 6.99) scores vs.(30.58 ± 3.92) scores,(64.06 ± 20.00) scores vs.(78.03 ±18.08) scores;t =3.96,4.90,2.50;all P ＜ 0.05].Corrected by Alphasim,patient group showed significantly increased ALFF in the left and fight temporal lobe,left and fight posterior lobe of cerebellum,right middle temporal gyrus,but ALFF decreased in the area of left and right lenticula,left putamen compared with the healthy control group (all P ＜ 0.05).The patients group showed that TMT scores were positively correlated with the value of ALFF in the right temporal lobe (r =0.67),and color scores were positively correlated with the value of ALFF in the right middle temporal gyrus (r =0.53),but colour scores were negatively correlated with the value of ALFF in the right tcmporal lobe (r =-0.54);the healthy control group showed that BVMT-R and digital span test scores were positively correlated with the value of ALFF in the left temporal lobe (r =0.47,0.41),but digital span test scores were negatively correlated with the value of ALFF in the right temporal lobe (r =-0.49),and colour scores were negatively correlated with the value of ALFF in the left temporal lobe (r =-0.35),while word and color-word scores were negatively correlated with the value of ALFF in the right middle temporal gyrus (r =-0.39,-0.36);the correlation coefficient above had statistical significance (all P ＜ 0.05).Conclusions The childhood and adolescence-first-onset OCD patients had cognitive impairment,including speed of processing,visual learning and memory,working memory;and the patients showed abnormal spontaneous neural activity at some brain regions.The cognitive dysfunction may be associated with abnormal spontaneous neuronal activity in childhood and adolescence-first-onset OCD.

Objective To detect the effect of hypoxia preconditioning on HIF-1α expression in the hippocampus of mice during acute and repeated hypoxia exposures. Methods Mice were randomly divided into 3 groups and were exposed to hypoxia for 4 runs ( H4 group) , 1 run ( H1 group) and 0 run ( control group). RT-PCR, Western blot and EMSA were used to examine the HIF-1α expression in the mouse hippocampus following exposure to hypoxia. Total mRNA,total protein and nuclear protein were extracted from the mouse hippocampus for RT-PCR, Western blot and EMSA respectively. Results HIF-1α mRNA levels were found to be increased in H1 and decreased in H4 (vs H1 ). HIF-1 α protein levels and HIF-1 DNA binding activities were increased in H1 and markedly increased in H4. Conclusion HIF-1 activation may be involved in the protection of the brain of hypoxia-preconditioned mice.

Objective To evaluate the performance of serum small dense low-density lipoprotein cholesterol(sdLDL-C)kit using enzymic method and evaluate the relationship with the severity of coronary heart disease.Methods Performance verification methodology. The analytical performance consisted of accuracy, precision and linearity of serum sdLDL-C kit using enzymic method was assessed. One hundred and twenty healthy persons were recruited to establish serum sdLDL-C reference interval. Two hundred and twelve patients underwent coronary angiography were enrolled in the study.Among them 110 cases were positive for coronary angiography, where as 102 cases were negative. We examined serum levels of sdLDL-C in 110 patients with positive angiography, 102 patients with negative angiography and 120 healthy volunteers. Positive group was classfied into severe group(Gensini score>30) and mild group (Gensini score≤30).Results The accuracy and precision of sdLDL-C examination were in compliance with manufacturer′s statement and there was a good linear correlation(Y=0.9937X-0.1063,R2=0.99) in range of 0.06-2.45 mmol/L. The reference interval of sdLDL-C was 0.15-0.97 mmol/L and without gender and age specificity. The level of sdLDL-C was higher in positive angiography group than in negative angiography group and healthy control group(P<0.01). The level of sdLDL-C was higher in severe group than in mild group(P<0.05). Binary stepwise regression analysis demonstrated that sdLDL-C was independently associated with the severity of coronary heart disease(OR=3.101,P<0.05).ConclusionsExperiment data demonstrated that serum sdLDL-C kit using enzymic method has good performance in the accuracy, precision and linearity. SdLDL-C that plays an important role in the occurrence and progression of coronary heart disease, is an independent important risk of the severity of coronary heart disease.
