Objective To observe the antihypertensive effect of indapamide combined with enalapril on spontaneously hypertensive rats(SHRs).Methods Forty SHRs were randomly divided into 4 groups: control,indapamide,enalapril,and indapamide+enalapril(n=10 in each group).Medicine in varied doses was given to rats by intragastric administration.Variations of weight,heart rate and blood pressure were measured. Results Varied doses of medicine did not exert significant effects to the weight and heart rate of SHRs during and after the administration.In indapamide+enalapril group,the pressure of SHRs was significantly decreased with varied doses compared to that before the administration(P

Objective：To explore the characteristics of behavioral problems and self-concept level in children with attention deficit hyperactivity disorder(ADHD)accompanying anxiety disorder.Methods：With stratified random sampling method,a sampling survey was made in 9495 children(aged 5～17 years)from 6 regions of Hunan province together.Using the two stage epidemiologic research method,three groups,including control group(214 cases),pure ADHD(219 cases)and ADHD accompanying anxiety disorder(111 cases)were determined as the subjects.All the subjects completed the Children's Self-Concept Scale(CSCS),and the Achenbach Child Behavior Checklist(CBCL)was completed by their parents.Results：(1)Compared to the control group,the pure ADHD group scored higher in CBCL [e.g.,the total score:(30.35±24.32)vs.(16.97±14.86)],and scored lower in CSCS [e.g.,total score:(50.85±9.98)vs.(57.46±10.80),P<0.05].(2)Compared to the control group,children with ADHD accompanying anxiety disorder scored higher in CBCL [e.g.,total score:(41.66±28.07),P<0.01],and in CSCS except physical activities(Ps<0.05).(3)Compared to the pure ADHD group,ADHD accompanying anxiety disorder group scored higher in CBCL and lower in CSCS[behavior:(10.44±3.17)vs.(11.55±2.80);anxiety:(8.06±2.61)vs.(9.21±2.61),gregariousness:(7.42±2.22)vs.(8.16±1.89);total score:(47.25±9.93)vs.(50.85±9.98);Ps<0.05].Conclusion：ADHD children have more behavioral problems and lower level of self-concept than normal children,and children with ADHD accompanying anxiety disorder have more prominent presence of behavioral problems and lower self-concept rating than children with pure ADHD.

Objective To find out the current situation of brucellosis infection and exposure status of family members of sheep farmers in the western pastoral areas of Jilin Province,and to provide a reference for control of human brucellosis spreading among family members.Methods On November 2012,Qianguo County was randomly selected using a multi-stage sampling method,and two townships,Chaganhua and Wulantala,were randomly selected in the county; half of the villages were selected from each township; all family members of the sheep farmers in these villages were investigated about their demographic characteristics (sex,age,education),high-risk behavior and information about brucellosis infection by using a questionnaire survey.Based on the principle of informed consent,respondents venous blood samples were collected.Brucellosis was confirmed with serum agglutination test (SAT).The effects of gender,age,education and other demographic data,high-risk behavior and high-risk behavior protection on the prevalence of brucellosis were studied.Results Out of the 403 copies of qualified questionnaires collected,84 people were found infected with brucellosis,and the infection rate was 20.84％ (84/403).Men infection [24.78％ (57/230)] was higher than that of women [15.61％ (27/173),x2 =5.038,P ＜ 0.05].The rates of eight kinds of high-risk behaviors were:helping feeding 86.85％ (350/403),cleaning sheepfold 80.40％ (324/403),holding lamp 71.71％ (289/403),delivering sheep 61.54％ (248/403),vaccinating sheep 53.85％ (217/403),apoblema 47.39％ (191/403),milking 22.08％ (89/403) and slaughtering sheep 14.89％ (60/403).The highest risk behavior was vaccinating sheep[24.40％(53/217)],and the lowest was milking [16.90％ (15/89)].The highest rate of basic protection was delivering a sheep [31.85％ (79/248)],the next was apoblema[27.23％ (52/191)],and the lowest was slaughtering sheep [8.33％ (5/60)].There was no statistical significant difference between brucellosis infection and the eight kinds of high-risk behaviors as well as the basic protective behaviors.Conclusions The prevalence of brucellosis infection among sheep farmers' family members is higher than others.Brucellosis infection-related contact manner is ubiquitous and the level of basic protection is low.We should carry out targeted health education on sheep farming household members to improve their level of protection,so as to reduce the risk of brucellosis infection.

Objective To establish the bedside screening scale for cognition examination in systemic lupus erythematosus patients.Methods The modified mini-mental status examination(MMMSE)(revised by the Neurology Department of Hua Shan Hospital)was applied to examine the recognition function of SLE pa- tients.The results were compared with those of the traditional mini-mental status examination(MMSE).Results MMSE examination results showed that NPSLE score was lower than that of normal control group(P＜0.01),no significant difference was found between NPSLE patients and SLE control group(P＞0,05),and the completion time was longer than SLE control group and normal control group(P＜0.01);but no significant difference was found between SLE control group and normal control group.The result of MMMSE examination showed that the score of NPSLE group was lower than that of SLE control group and normal control group(P＜0.01),and the completion time was longer than SLE control group and normal control group(P＜0.01);but the score of SLE control group was lower than the normal control group,and its completion time was longer than normal control group,the difference was statistically significant(P＜0.01).Conclusion MMSE is the most widely used dementia scale,but it is not sensitive in demonstrating the impairment of recognition function.The several items we added to the MMMSE can detect recognition impairment more sensitively,and ean be very easily applied,costs less time(within 10 minutes).Therefore,it can be used for SLE bedside screening.

AIM: To compare the contents of baicalin,paeoniflorin and glycyrrhetic acid in the seperated and mixed decoction of Huangqin Decoction(Radix Scutellariae,Radix Paeoniae alba,Radix et Rhizoma Glycyrrhizae and Fructus Jujubae). METHODS: The contents of baicalin,paeoniflorin and glycyrrhetic acid were analyzed by HPLC.Chromatographic conditions included: Hypersil BDS C_(18) column and the mobile phase consisted of a mixture of methanol-water-phosphoric acid(47(∶)53(∶)0.2),acetonitrile-water-phosphoric acid(18(∶)82(∶)0.1) and methanol-water-phosphate buffer solution(70(∶)29(∶)1).Baicalin,paeoniflorin and glycyrrhetic acid were detected at 280 nm,230 nm and 250 nm respectively. RESULTS: The linear range of baicalin,paeoniflorin and glycyrrhetic acid were 2.88—72.00 ?g/mL,2.85—22.80 ?g/mL and 4.16—52.00 ?g/mL respectively.The contents of baicalin in the mixed decoction was higher than that in the seperated decoction.The contents of paeoniflorin and glycyrrhetic acid in the mixed decoction were almost as same as that in seperated decoction. CONCLUSION: The contents of active ingredients in the mixed and seperated decoction are different.

Objective To investigate children′s myelodysplastic hematopoietic cells reaction to interleukin (IL)-15.Methods CD 34 + cells in bone marrow from 18 myelodysplast syndrome(MDS) patients were purified by an immunomagnetic beads sorting system. Apoptosis of hematopoietic precursors was assayed by propidium iodine staining and flow cytometric analysis.Results On 8th cultured day,when IL-15 concentration was between 0-100 ng/ml,it could suppress apoptosis of hematopoietic cells in MDS patients in a dose-and- time dependent manner. IL-15 in study group significanthy lower than that of control group.Conclusion IL-15 may partly suppress apoptosis of hematopoietic cells in MDS patients.

Diabetes surgery is a new concept in recent years, which means controlling blood sugar or curing diabetes through some surgical methods. From the commencement of bariatric surgery in the 1950s to the discovery of the special function of decreasing blood sugar after these surgeries in 1970s, and then the fast developing of diabetes surgery in the past 30 years, now there seems be a different answer to the question that if we can cure diabetes. In this article, we review the historical evolution, surgical procedure, potential mechanism and outlook of diabetes surgery.

OBJECTIVETo study the clinical characteristics of Mycoplasma pneumoniae (MP)-associated ischemic stroke in children.

METHODSThe case of a girl with MP-associated ischemic stroke was reported, including clinical manifestations and laboratory and imaging examinations, and related literature was reviewed.

RESULTSThe girl, who was suffering from a respiratory tract infection was found to have hemiplegia and aphasia which were expressed in ischemic stroke. IgM antibody to MP in serum (1∶320) and lavage fluid was positive. Pulmonary imaging showed unilateral consolidation and pleural exudate. Cerebral neuroimaging examination showed occlusion of the bilateral middle cerebral artery, mainly on the left side. The neurological symptoms and signs were recovered after comprehensive therapy with medication (azithromycin, hormone and heparin) and rehabilitation training.

CONCLUSIONSIschemic stroke is rare but severe manifestation of central nervous system damage in children suffering from MP infection. Cerebral imaging and etiological examinations contribute to the diagnosis. Early use of macrolide antibiotics, anticoagulant and hormone may improve the prognosis.

BACKGROUNDThe ideal post-gastrectomy reconstruction procedure should maintain the normal digestive function and restore intestinal transit to improve the patient quality of life. The aim of this study was to evaluate the effects of integral continual jejunal interposition after subtotal gastrectomy on the nutritional status, glucose levels, and gastric-intestinal motility.

METHODSThe study investigated the effects of the integral continual jejunal interposition, the Billroth I and Billroth II operations, and the isolated jejunal interposition following subtotal distal gastrectomy on the blood glucose, insulin, routine blood parameters, liver function, and myoelectrical activity in Beagle dogs.

RESULTSThe weights of the dogs decreased during the first post-operative weeks. Dogs in the integral continual jejunal interposition, Billroth I, and Billroth II groups gained significantly more weight by 8 weeks. The prognosis nutrition index of the dogs decreased in the first 2 post-operative weeks and increased significantly by 4 weeks in the integral continual jejunal interposition and Billroth I groups. The group with duodenal exclusion (Billroth II) had significantly higher glucose levels compared to the normal control group. The insulin curve was much higher in dogs that underwent the Billroth I, continual jejunal interposition, and isolated jejunal interposition than the Billroth II and normal groups. The frequencies of fasting and postprandial jejunal pacesetter potentials (PPs) were greater in the continual jejunal interposition and Billroth I groups than that in the isolated jejunal interposition and Billroth II groups. The percentage of aboral propagation of PPs was greater in the continual jejunal interposition group than the Billroth I, isolated jejunal interposition, and Billroth II groups.

CONCLUSIONContinual jejunal interposition after subtotal gastrectomy avoids jejunal transection, maintains the duodenal passage and food storage bags, and reduces the influence of blood glucose and insulin.
