Objective To evaluate T-lymphocyte subsets and sjTREC gene level in sepsis children and to provide a reasonable theoretical basis for immune regulation. Methods This prospective study was performed on children who were classified as sepsis group (n = 25), severe sepsis group (n = 23), and control group (n = 50). The T cell subsets were measured before the blood products,immune agents,and nutritional support were administrated. By real-time fluorescence quantitive-PCR method, the sjTREC levels of the patients with sepsis and healthy children were quantitatively detected respectively;then the sjTREC levels were absolutely quantified by two standard curve method. The results were demonstrated by sjTREC and endogenous reference gene (Cα) copies ratio (sjTREC/Cα× 2 × 1000) and statistically analyzed by SPSS 16. 0 software. Results The levels of CD3 +, CD4 +, and CD8 + T cells in severe sepsis group were lower than those in control group (P＜0.01). The level of sjTREC of severe sepsis group was 173.86 +38.37,which was significantly lower than those of sepsis group (345. 15 ± 66. 21) and control group (389. 42 ± 50. 20) (P ＜ 0. 01). Conclusion Children with severe sepsis have a range of T-lymphocyte subsets disorders and decreased thymic output function, so early immunotherapy can improve clinical outcome.

Objective To investigate pediatric infective endocarditis(IE) risk factors and the feature of pathogen.Methods We conducted a retrospective study of 46 cases who were diagnosed as IE from January 2000 to June 2007.Sixteen variables such as sex,primary disease,infectious site,complication,culture result and therapeutic measure were selected for logistic regression analysis.Results Forty-six IE patients accounted for 0.78‰ of all the hospitalized patients during the same period.Of 46 cases,40 had heart diseases.The incidence rate of left-sided endocarditis was higher than that of right-sided endocarditis.Twenty-four had positive blood culture result,one patient had positive culture from vegetation sample.The total positive culture rate was 54%.Gram-positive bacteria were found in 15 cases,and the most common organisms were α-hemolytic streptococcus.Gram-negative bacteria were in 7 cases and fungus infection was present in 3 cases.After antiboitic treatment,40 were cured,6 died.In the logistic regression model,the variables significantly associated with death included negative blood culture (OR=25.127,95%CI=1.110-363.236),hematological system disease (OR=28.620,95%CI=2.261-354.448) and multiple organ failure (OR=19.843,95%CI=0.786-221.754).Conclusion Streptococcus viridans is the most common pathogen in pediatric IE in our hospital.Higher incidence in the left heart than that in the right heart is found.Negative blood culture,hematological system disease and MOF are the risk factors in IE patients.

Objective:To explore the effect of dialysis pipeline nursing group mode combined with predictive nursing measures on hemodialysis efficacy of diabetic nephropathy patients with maintenance hemodialysis (MHD).Methods:A total of 96 patients with MHD of diabetic nephropathy admitted to No. 904 Hospital of Joint Logistics Support Force of Chinese People's Liberation Army from January 2015 to December 2019 were selected as the research objects and divided into control group and observation group, 48 cases in each group. Patients in the control group were treated with routine dialysis pipeline and other hemodialysis nursing interventions, while patients in the observation group were treated with predictive nursing measures on this basis. The biochemical indexes, psychological state, compliance, incidence of nosocomial infection and complications and nursing satisfaction of the two groups before and after intervention were compared.Results:After the nursing intervention, the blood urea nitrogen (BUN), creatinine (Cr), and β2 microglobulin (β2-MG) of the two groups of patients were lower than those before the intervention, and the BUN of the observation group after the intervention, Cr and β2-MG were (12.04±1.98) mmol/L, (451.62±82.49) μmol/L, (13.53±2.31) mg/L, respectively, which were lower than those of the control group (15.82±2.31) mmol/L, (591.35±99.21) μmol/L, (18.83±2.92) mg/L, the difference was statistically significant ( t value was 8.608, 7.503, 9.862, P<0.05). After the intervention, the scores of the treatment compliance subscales of the observation group were 29.06±3.58, 23.42±2.99, 20.11±3.01, 14.76±2.94, which were higher than those of the control group (31.91±3.97, 21.53±3.21, 17.03±2.74, 12.36±3.04), the difference was statistically significant ( t value was 2.985-3.932, P<0.05). After the intervention, the SAS and SDS scores of the two groups were lower than those before the intervention, and the SAS and SDS scores of the observation group after intervention were 39.12±4.82 and 36.43±6.03, which were lower than those of the control group 48.25±5.14, 46.75±5.36, the difference was statistically significant ( t value was 8.997, 8.862, P<0.05). The incidence of nosocomial infections and complications in the observation group were 2.08% (1/48) and 4.17% (2/48), which were significantly lower than those in the control group, 14.58% (7/48) and 18.75% (9/48), The difference was statistically significant ( χ2 value was 4.91, 5.26, P<0.05). The nursing satisfaction degree of the observation group was 95.83% (46/48), which was higher than 72.92% (35/48) of the control group, and the difference was statistically significant ( χ2 value was 9.56, P<0.05). Conclusions:The dialysis pipeline combined with predictive nursing can improve the psychological state of patients, reduce the incidence of hospital infection and complications, prolong the service life of vascular access, improve the quality of life of hemodialysis patients, improve the relationship between nurses and patients, and create a harmonious atmosphere, which is worthy of clinical promotion and application.

Objective To discuss the selection of different operation methods for cesarean scar pregnancy ( CSP ) . Methods A retrospective analysis was made on clinical data of 71 CSP patients treated in our hospital from January 2010 to January 2015.All the patients were accurately diagnosed by transvaginal color ultrasound examinations.Hysteroscopic evacuation was performed in 45 endogenous CSP patients, while in 26 exogenous CSP patients, 15 of them were treated by hysteroscopy and the other 11 patients were given laparoscopic operation. Results For the 45 endogenous patients, the success rate of hysteroscopic therapy was 92%( 41/45 ) .For the 26 exogenous patients, the success rate was 80% ( 12/15 ) for hysteroscopic and 82% ( 9/11 ) for laparoscopic therapy. Conclusions Preoperative categorizing of CSP is important for choosing different surgery methods. Hysteroscopic evacuation is the first choice for endogenous CSP.For exogenous patients, both hysteroscopic evacuation and laparotomy can be chosen.Therefore, the two minimally invasive procedures have limits, and transvaginal and laparotomy resection of lesion is still necessary sometimes.

ObjectiveTo observe the effects of mild hypothermia on post-resuscitation myocardial dysfunction in rabbits in order to elucidate the underlying mechanism of hypothermia.Methods After setting up rabbit model of cardiopulmonary resuscitation,20 rabbits were randomly ( random number)divided into two groups,namely normothermic resuscitation group (group A,n =10 ) and post-ROSC hypothermia group ( group B,n =10).In the group A,animals wore treated with standard CPR after cardiac arrest.In post-ROSC hypothermia group,the body temperature of animals was cooled to 32 ～ 34°C after successful ROSC.The left ventricular end-diastolic pressure (LVEDP),left ventricular pressure rise and fall rates ( ± dp/dtmax,serum concentrations of heart-type fatty acid-binding protein (H-FABP) and 8-isoprostaglandin F2a (8-iso-PGF2a) and Cyclooxygenase-2 (COX-2) were observed. Results Compared with the A group,the B group had significantly better hemodynamics,and lower serum H-FABP,8-isoPGF2a and COX-2 levels in the early stage of post-resuscitation ( both P ＜ 0.05 ).ConclusionsMild hypothermia attenuated post-resuscitation myocardial dysfunction during the early period of postresuscitation.The cryoprotective effect on myooardium is likely associated with the reduction of 8-iso-PGF2a and COX-2.

Objective Alterations in vascular structure and function and impairment of associated endothelial cells with aging are one of the independent risk factors in the process of atherosclerotic vascular diseases.The study of age-related endothelial dysfunction plays a critical role in preventing as well as treating heart and cerebral vascular diseases in the elderly.Methods The healthy male rats were divided into the young group (3-month-old),the adult group (9-month-old) and the middle-aged group (15-monthold).The indicators associated with vascular endothelial function,including plasma NO,eNOS,iNOS,ET-1 and aortic NO,eNOS,iNOS,were quantified to evaluate the endothelium-dependent and non-endothelium-dependent vasodilating function of isolated aortic rings.These morphological changes of rat aorta helped to find out the group in which endothelial function changed in the early stage.Results Plasma NO,eNOS,iNOS and aortic NOS activity in the young group,the adult group and the middle-aged group gradually decreased with increasing age (P ＜ 0.05).NO,eNOS and iNOS respectively displayed a negative correlation to age.ET-1 gradually increased with aging (P ＜ 0.05) and showed a predominantly positive correlation to age.Acetylcholine-induced greatest vasodilation of aortic rings lessened with increasing age (P ＜ 0.05).Vasodilation in each group reacted generally consistently with nitroprusside sodium (P ＞0.05).Aortic morphology,including intima media thickness (T),diameter (D) and intima media thickness / inner diameter (T / D),gradually enhanced with aging (P ＜ 0.05).T,D was positively correlated with age.NO,eNOS,iNOS,ET-1 of the adult group showed maximum slope (P ＜0.05 respectively) according to group regression analysis,suggesting that vascular endothelial function changed in this group.Meanwhile,T and D of the middle-aged group showed maximum slope (P ＜ 0.05 respectively),suggesting that age-related vascular structural changes predominantly occurred in this period and vascular function changed earlier than the structure.Conclusion Our study demonstrated vascular endothelial dysfunction with aging.Early evident changes of endothelial function occurred in the adult group,which impaired endothelium-dependent vasodilating function.Vascular function changed earlier than the structure.

ObjectiveTo study the liver and kidney function and muscle effects of rosuvastatin in rats.MethodsIn this study,twenty healthy male rats (9-month-old) were randomly divided into two groups:normal control group and rosuvastatin treatment group.The first treated group was given conventional feed; The second treated group was given conventional feed and oral rosuvastatin [5mg/( kg · d)] of 12 weeks.The level of liver and kidney function and creatine kinase,histological changes of liver and muscle were examined before and after the treatment.ResultsOur findings demonstrate that the level of liver and kidney function and creatine kinase was no significant difference among the two experimental groups,also no difference before and after treatment( P ＞0.05).At the same time,liver and muscle showed no abnormal pathology.Conclusion These findings collectively indicate that rosuvastatin shows no significant side effects in the liver and kidney function and muscle pathology compared with control group.
