Objective To understand the characteristics of malaria endemic situation in Dongtai City from 1999 to 2013. Methods The data of diagnosed malaria cases and related information of prevention and treatment were collected and analyzed with the epidemiological method. Results From 1999 to 2013 there were 27 malaria cases in total and among which 2 cases were local-infected with Plasmodium vivax 10 cases were imported P. vivax infections 13 cases were imported P. falciparum infections and 1 case was a mixed infections P. falciparum P. vivax and P. ovale . The imported cases accounted for 92.59%and local-infected cases accounted for 7.41%. There were no local-infected cases after 2003 and all the cases were overseas-im-ported. The main first-diagnosis points were town hospitals and village health stations accounting for 33.33%and 33.33%re-spectively. Totally 62.96%of cases visited the clinic in 1 day after the attacking the median of time-interval from the attacking to visiting the clinic was 1 day the median of time-interval from the attacking to confirmed diagnosis was 3 days and the max time from the attacking to confirmed diagnosis was 33 days. Conclusion The malaria cases are mainly imported cases in Dong-tai City from 1999 to 2013 and therefore the key of eliminating malaria should be the monitoring of the retuned exporting la-bors.

Objective To investigate the significance of bone mineral changes in the pathogenic process of glucocorticoid-induced avascular necrosis of femoral head(GANFH).Methods Thirty-two New Zealand rabbits were randomly divided into two groups(16 each).Animals in model group received an intramuscular injection of hydrocortisone acetate(8.0mg/kg) twice a week for 8 weeks totally,and animals in control group received an intramuscular injection with the same volume of normal saline,while 150kU penicillin were injected twice a week for preventing infection in both groups.The contents of serum calcium(Ca) and phosphorus(P) were determined,and the bone mineral densities of the femoral head and neck were measured at the 2nd,4th,6th,8th and 12th weeks after treatment.Meanwhile,the general condition such as weight,spirit and hair of rabbits was observed.Results Compared with the control group,the weight of rabbits in model group lost since the first week,and progressively aggravated;the bone mineral density of the femoral head and neck lowered since the 2nd and 4th week respectively(P

Objective To investigate the clinical significance of cell function changes of bone tissue in glucocorticoid-induced avascular necrosis of femoral head(GANFH),and the preventive and therapeutic effects of "Cugusugao" ointment,a mixture of traditional Chinese medicines,on GANFH.Methods Sixty-four New Zealand white rabbits were randomly divided into four groups(16 each): control group,model group,therapy group and prevention group.The contents of bone-specific alkaline phosphatase(BSAP) and bone gla protein(BGP),and the activity of tartrate-resistant acid phosphatase(TRAP) in serum were determined at the 0,2nd,4th,6th,8th and 12th week after treatment.Meanwhile,rabbits were sacrificed at the 4th,6th,8th and 12th week,and bilateral femoral heads were obtained for histopathological examination.Results Compared with control group,the contents of serum BSAP were elevated at the 4th and 6th week,while TRAP elevated from the 2nd week and BGP lowered from the 4th week in model group(P

Objective To investigate the additive effects of uncoupling protein 2(UCP2) gene 3′-untranslated region(3′-UTR) 45-base pair insertion/deletion( I/D) variation and peroxisome proliferator activated receptor( PPAR)γ2 gene Pro12Ala variation on type 2 diabetes(T2DM) in Chinese Han popula-tion.Methods The UCP2 gene 3′-UTR I/D variation and PPARγ2 gene Pro12Ala variation were exam-ined by polymerase chain reaction-restriction fragment length polymorphism ( PCR-RFLP) in 490 type 2 dia-betes subjects and in 585 control subjects .The additive effects of the two gene mutations were analyzed . Results ⑴The frequency of PPARγ2 gene Pro12Ala variation in type 2 diabetes was not significantly dif-ferent from that in control subjects.(χ2 =0.058, P =0.809).In T2DM group, A12 allele carriers had larger waist circumference than Pro12Pro genotype carriers;Glucose stimulated insulin secretion by oral glu-cose tolerance test (OGTT) was significantly lower in carriers of the Ala12Ala or Pro12Ala genotype com-pared with Pro12Pro genotype.( Z =2.222, P =0.026; Z =2.051, P =0.040; Z =2.079, P =0.038 ) .⑵There wasn't significant difference among 3 genotypes with 3′-UTR I/D variation in UCP2 gene (χ2 =2.311 , P =0.315 ) .In control group , Glucose stimulated insulin secretion by oral glucose tolerance test ( OGTT) was significantly higher in carriers of the I/D or I/I genotype compared with D/D genotype ( Z =1.997 , P =0.046 ) .⑶The genotype carriers with Pro/Ala +Del/Del were the greatest relation to T2DM (OR=1.22, 95%CI 1.078~1.386).Conclusion Though the UCP2 gene mutation alone or the PPARγ2 gene mutation alone is not associated with T 2DM, the possible additive effects of the two micro genes increase the occurring of T 2DM.

Objective To study the effects of hirudo extract liquor(HEL) on the expressions of HSP70 and TGF?-1 in intracerebral perihematoma tissues of rats.Methods We established the experimental ICH models in Wistar rats by stereotaxical injecting quantitative collagenase(0.7 U collagenaseⅦ) into their left caudate nuclei.The rats continued to be treated with HEL(treatment group) or normal saline(control group) through intravenous injection by vena caudalis and the scores of neurologic impairment in two groups were evaluated every day.The slices of these samples at 3rd,6th and 10th day were stained by immunohistochemistry and the positive cells of HSP70 and TGF?-1 were counted by image analysis system,respectively.Results The scores of neurologic impairment in two groups were remarkably reduced with time going((P

40 cm H 2O (1 cm H 2O=0.098 kPa) in 4.Among the 5 children without urinary complaints,2 had detrusor hyperreflexia,2 had detrusor-sphincter dyssynergia,and 1 was generally normal.Postoperatively the improvement of urinary incontinence rate was greater in patients with primary TCS (28.6%,8/28) than those with secondary TCS (0%,0/7;P=0.048). It was greater in patients with non-lipoma TCS (100%,3/3) than those with lipoma TCS ( 15.6%,5/32;P=0.004).It was greater in patients with meningocele TCS (36.4%,8/22) than those with myelomeningocele TCS(0%,0/6;P=0.047).It was greater in patients born without urological symptoms (80%,4/5) than those born with urological symptoms(17.4%,4/23;P=0.019).Urodynamic studies also showed the incidence of detrusor hyperreflexia after surgery was lower in primary TCS (24.2%,8/32) than in secondary TCS(71.4%,5/7;P=0.015);the incidence of detrusor underactivity was lower in non-lipoma TCS (12.5%,1/8) than in lipoma TCS(56.3%,18/32;P=0.027);decreased compliance rate was lower in meningocele TCS than in myelomeningocele TCS(100%,6/6;P=0.0052).The rates of detrusor hyperreflexia,decreased compliance and detrusor underactivity postoperatively were lower in those born without urinary symptoms (0,0/10;20%,2/10;20%,2/10) than in those with (34.89%,8/23;60.9%,14/23; 65.2%,15/23;P=0.032,P=0.031,P=0.017, respectively). Conclusions Urodynamic examinations are effective in evaluating the lower urinary tract function in children with TCS after surgery.Patients with TCS have various abnormal urodynamic findings.Pathological types of TCS and the presence of symptoms at birth influence urinary function after surgery.

Objective Randomly sampling survey was performed among the troops stationed in the monitoring sites during the period of 2006-2007 for understanding and analyzing the incidence,distribution and the epidemiological features of military training related injuries(MTRI).Methods Troops stationed in 9 monitoring sites were randomly selected for the survey,and soldiers participated in military training during the period of 2006-2007 served as the objects.The data concerning the military training injuries were collected and analyzed according to the "Diagnostic Criteria and Treatment Principle on Military Training Related Injury".Results 6262 out of 71836 soldiers who participated in assorted military training during the period of 2006-2007 suffered from military training related injuries.Among them 2455 out of 35582 soldiers who participated in military training in 2006 suffered the injuries,with an incidence of 6.9%;while 3807 out of 36254 soldiers who participated in military training in 2007 suffered the injuries,with an incidence of 10.5%.A significant difference existed in the incidence of military training related injuries between the years of 2006 and 2007(P

Objective To investigate the association of CA repeats polymorphism in the promoter region of human IGF-I gene with type 2 diabetes in narthen Han nationality. Methods Gender-age matched subjects with type 2 diabetes and normal glucose tolerance (NGT) were enrolled for this study, 147 subjects in type 2 diabetes group and 159 subjects in NGT group. Genomic DNA was extracted by standard methods. PCR, Genescan,Genotyper, and direct sequencing were conducted to screen CA repeats polymorphism in the promoter region of the human IGF-I gene. Results No significant association was observed between any ( CA), repeat genotype and type 2 diabetes. A lowered serum uric acid was seen in genotypes that included alleles with larger than (CA) 20 repeats [(4.18 ± 1.25 vs 4.63 ± 1.36) mg/dl, P = 0.03]. Conclusion Alleles with larger than (CA) 20 repeats may be a protective factor for type 2 diabetes.

Objective To find time pint of the irreversible kidney injuru by observing renal pathological appearance and podocytes phenotype after complete ureteral obstruction.Methods The animal model of complete unilateral uretersal obstruction was consructed in 2-weekold and 2-month-old rats respectively.HE staining was employed to evaluate the degree of pathological changes,and immunofluorescence double staining to observe the transitional progression of podocyte.Results Grossly,there appeared pyelectasis at 2 h after obstruction and thinner renal cortex after 3 days of obstruction.Histologically,proximal tube display dilated and hydropic degeneration of tubular epithelial cells was observed after 12-day obstruction.The tubular epithelium showed distorted swelling after 3-day obstruction.Immunofluorescence double staining showed that podocytes decreased and the double-labeled macrophages was increased during 1 d to 2 d after unilateral ureteral obstruction operation.Conclusion Compared with control groups,the unilateral ureteral obstruction groups shows podocyte-to-macrophage transition at 1 d after the operation, while the pelvis shows obviously dilated.From the 1st day to the 7th day after unilateral ureteral obstruction,it shows increasing tendency of the podocytes transition.
