Objective To explore the relationship between pulse pressure (PP) and artery atherosclerosis in elders. Methods Totally 2358 eiders( > 60y) with the risk factors of artery atherosclerosis from Yangpu District DOI:10.3760/cma.j.issn.1008-6315.2009.09.006Central Hospital and 11 Community Health Service Centers were enrolled . The basic information includes age, sex, height,body mass, history of smoking, blood pressure, heart rate, history of coronary heart disease, ischemic stoke, chronic kidney diseases and diabetes,etc. The fasting blood sugar(FBS) ,blood lipid( total cholesterel,triglyceride, low-density lipreprotein, high-deusity liproprotein), serum creatinine, serum uric acid, serum alanine aminotransferase were measured. The elders were divided into two groups according to the PP( PP <60 mm Hg and PP≥60 mm Hg) to analyse the relationship between PP and age, BMI, SBP, DBP, HR, FBS, TC, TG, LDL-C, HDL-C, Cr, Ccr, UA, AST and history of coronary heart disease,ischemic stoke,chronic renal disease, and diabetes. Results Serum levels of FBS,TC,TG, LDL-C, UA in the group with PP less than 60 nun Hg were ( 5.6±1.7 ) mmol/L, (4.3±1.3 ) mmol/L, ( 1.5±1.2) mmol/L, ( 2.5±1.1 ) mmol/L, UA ( 246.8±131.2 ) μmol/L, that in the group with PP over or equal to 60 mm Hg group were (6.3±2.6) mmol/L, (4.8±1.2) mmol/L, ( 1.9±1.1 ) mmol/L, (2.9±1.2) mmol/L, (291.4±133.6) μmol/L, Serum levels of FBS, TC, TG, LDL-C, UA in the group with PP over 60 mm Hg were obviously elevated as compared with that in the group with PP lower than 60 ram Hg(P <0.01 ) ; The preven-lence rates of coronary heart disease ischemic stoke,chronic,renal disease, diabetes in the group with PP less than 60 mm Hg were 10.8% ,26.0%, 12.4%, 17.6%, that in the group with PP over or equal to 60 mm Hg group were 17.8% 、31.7% ,16.9% ,23.8% (P <0.01 ). The preveulence of coronary heart disease ischemic stoke,chronic re-nal disease, diabetes were significandy increased in the group with PP over or equal to 60 mm Hg group. Logistic re-gression analysis showed PP was closely related to FBS, BMI, age, LDL-C, UA, HDL-C ( β = 0.103,0.093.0.097, 0.089 ,0.076 , - 0.057, P < 0.05 ). Conclusions For those elders with the basis of artery atherosclerosis, high PP can inhance the development of artery atheresclerosis and also inhance the occurance and development of cardio-ce-rebrovascular and renal diseases.

Objectives To compare the dose distribution of the whole body γ-knife and three-dimensional conformal radiotherapy (3D-CRT) in the treatment of primary hepatic carcinoma to provide evidence for clinical treatment choice.Methods Totally 35 patients with primary hepatic carcinoma treated with whole body γ-knife from March 2014 to July 2015 underwent three-dimensional conformal radiotherapy planning,and dose volume histograms were used to evaluate the dose distribution of target volumes and normal tissue,and moreover conformity index (CI) and homogeneity index (HI) were analyzed.Results Between the two treatment plans,D98 and the mean dose Da of GTV were higher in whole body γ-knife plan than those in three-dimensional conformal radiotherapy plan.For PTV,the V95 of γ-knife and three-dimensional conformal radiotherapy were (95.05±0.02)％ and (90.00±0.03)％ (P=0.00) respectively.Target coverage of whole body γ-knife was better.For organ at risk,γ-knife showed better protection of normal tissue.Three-dimensional conformal radiotherapy showed better HI (GTV:0.11±0.15 vs 0.23±0.02,PTV:0.14±0.04 vs 0.21±0.03),while more normal liver tissue received excessive exposure.The whole body γ-knife increased dose of target volumes and decreased dose of normal tissue,while three-dimensional conformal radiotherapy showed better HI.Conclusion Compared with three-dimensional conformal radiotherapy,the whole body γ-knife shows advantage in dose distribution but HI of target volumes.For clinical using,appropriate treatment needs to be chosen according to the patients' actual situation.

Background Basic fibroblast growth factor(bFGF)secreted by cornea after injury is important to cytothesis,collagen fibers reconstruction and axons recovery.However,the local bFGF is not enough for the reparation process.Objective This study aimed to observe the findings of corneal collagen and nerve recovery under the confocal microscopy through focusing(CMTF) in the eyes with intervene of exogenous recombinant bFGF(rbFGF) after excimer laser in situ keratomileusis(LASIK).Methods LASIK rabbit models were binocularly created in 34 clean New Zealand white rabbits.The tobramycin combined with dexamethasone were dropped after operation for 10 days in bilateral eyes.rbFGF was topically administered in the right eyes of rabbits from 1 day through 3 months after LASIK,and lubricant was used in the left eyes at the same way.The corneal collagen and nerve recovery,keratocyte and endothelial cell counting were observed with CMTF at the 1st week,2nd week,2nd month,3rd month and 5th month after LASIK.Results Total 19 rabbits were meted the request of LASIK models.The keratocyte densities in anterior stroma of both groups reached the lowest level at the 2nd week and the highest level at the 3rd month.Otherwise,haze changed on the contrary.No statistically significant differences were found in anterior stroma keratocyte densities,haze grade,grey value between rbFGF group and lubricant group at various time points after operation(P＞0.05).The nerve cord densities of both groups were increased gradually,and those under the epithelial basement membrane were more dominant.The nerve density of the anterior stroma of rbFGF group was significant higher than the lubricant one in the 2nd group(P=0.038).The considerably elevated the subepithelial nerve density value was also seen in rbFGF group compared with lubricant at 5 months after operation(Z=-2.060,P=0.039).No any corneal neovascularization occurred in both groups through experiment duration.The positive correlation was found between grey value with haze grade in rbFGF group(b=22.687,F=37.975,P=0.000) and lubricant group(b=20.410,F=18.516,P=0.000).However,haze grade was not significant correlated with stromal keratocyte density(rbFGF group:b=0.001,F=0.164,P=0.668;lubricant group:b=-0.002,F=1.896,P=0.178).Conclusion Exogenous bFGF can improve the recovery of corneal nerve and regeneration of keratocyte after LASIK.No evidence of bFGF promoting corneal neovascularization is found in this experiment.

To investigate the effects of carbamazepine (CBZ) on the plasma concentrations of valproic acid (VPA) and its toxic metabolite 2-propyl-4-pentenoic acid (4-ene VPA) in epileptic patients, the plasma concentrations of VPA and 4-ene VPA were determined, and the effect of CBZ on pharmacokinetics of VPA was evaluated. All patients had been divided into two groups (VPA group, n = 87; and VPA+CBZ group, n = 19). As compared to VPA group, the combination of CBZ significantly (P < 0.01) decreased the trough concentration of VPA [VPA group, (69.5 +/- 28.8) microg x mL(-1); VPA+CBZ group, (46.3 +/- 25.6) microg x mL(-1)] and does-adjusted VPA trough concentration [VPA group, (4.89 +/- 2.21) microg x mL(-1) x mg(-1) x kg(-1); VPA+CBZ group, (3.14 +/- 1.74) microg x mL(-1) x mg(-1) x kg(-1)]. However, the addition of CBZ did not influence the concentration of 4-ene VPA. The present study revealed that coadministration of CBZ can reduce VPA plasma concentration and may impact VPA clinical effect, therefore therapeutic drug mornitoring of VPA should be used when combined use of CBZ and VPA.

OBJECTIVETo investigate the efficiency of multiplex ligation-dependent probe amplification (MLPA) combined with short tandem repeat (STR) linkage analysis for the prenatal diagnosis for Duchenne muscular dystrophy (DMD).

METHODSGender of the fetus was first determined by the presence of Y chromosome sex-determining gene (SRY). Subsequently, combined MLPA and STR linkage analysis were applied for the probands, pregnant women and fetuses in 45 affected families.

RESULTSAmong the 45 families, 31 SRY-positive fetuses were identified, among whom six were diagnosed with DMD. For 14 SRY-negative fetuses, four were diagnosed as carriers. The remainders were normal.

CONCLUSIONMLPA can detect mutations in the exons of dystrophin gene, whilst STR linkage analysis can determine whether the fetus has inherited the maternal X chromosome bearing the mutant gene. As the result, the method can detect affected fetuses in which no exonic mutations are detected with MLPA. By combining the two methods, the diagnostic rate for DMD can be greatly improved.

Objective To study the family rearing pattern of attention deficit hyperactivity disorder(ADHD)with or without anxiety disorder and to explore its risk factors.Methods 9495 children and their parents were sampled at random in Hunan province,using two-stage investigation.Those who were diagnosed ADHD and the normal control filled out Egna Minnen av Barndoms Uppfostran and family adaptability and cohesion scale bv themselves.Results The comparison of factors as:actual family cohesion,parents' punishments,reiection,mother's excessive protection,intervention and father's excessive protection were significantly difierent between ADHD with or without anxiety disorder and normal children(P＜0.05).The comparison of parents' punishments,reiection,excessive protection and intervention were obviously different between ADHD with anxiety disorder and simple ADHD(P＜0.05).Mother's reiection was the influencing factor of simple ADHD,with OR as 1.122.Ideal family cohesion,mother's rejection and father's punishments were the influencing factors of ADHD with anxiety disorder,with OR as 0.966.1.215 and 1.089 respectively.Conclusion There were some problems in the parental rearing pattern of ADHD with or without anxiety disorder.Mother's rejection,father's punishments and ideal family cohesion were suggested to be correlated with ADHD and anxiety disorder.

OBJECTIVETo investigate the prevalence of psychiatric disorders in a representative sample of primary and middle school students in Hunan Province.

METHODSA total of 9 495 children aged 5-17 years from Hunan urban and rural schools were enrolled by a cluster sampling and a two-phase design. The students' psychiatric status was assessed using the Investigation Screening Inventory for Child Mental Disorder and a semi-structured interview designed based on the DSM-IV criteria.

RESULTSThe overall prevalence of psychiatric disorders was 16.22%. Attention-deficit and disruptive behavior disorders were the commonest in the diagnostic categories of psychiatric disorders (10.69%). Regarding specific disorders, the most prevalent was attention-deficit/hyperactivity disorder (5.95%). Psychiatric disorders were more prevalent in boys than in girls (20.49% vs 11.16%; p<0.01). The prevalence of attention-deficit and disruptive behavior disorders in boys was higher than in girls (14.76% vs 5.87%; p<0.01). The prevalence of psychiatric disorders in middle school students (12-17 years) was significantly higher than in primary students (5-11 years) (18.38% vs 14.64%; p<0.01). There were no significant differences in the prevalence of psychiatric disorders between urban and rural students.

CONCLUSIONSPsychiatric disorders are common among primary and middle school students in Hunan Province. The prevalence of this disorder in boys is higher than in girls. The middle school students have higher prevalence than primary students.
