Objective To probe into the changes of rats' plasma SOD,MDA,NO and rectal temperature at moist heat and wound stress in order to build a basis for research of enhancing resistance to stress resporise in human. Methods 56 moist beat and wound rats were randomly divided into the control group and the nutrition group with 28 rats in each group.then each group was subsequently divided into 4 period oftime.All the backs of rats were scalded in superficial degree Ⅱ by 99℃water and exposed to the same conditions:temperature at(37.O±0.5)℃and relative humidity at(65±5)%.The control group' was imbued with double-distilled water for one week,while in the nutrition group,compound nutrient was imbued for one week.SOD,MDA,NO and rectal temperature at 4 time points were compared between the two groups.Results The differences of rectal temperature,NO and SOD changes between the control group and the nutrition group were remarkably significant.Conclusions Early nutrition is effective in reducing stress,decreasing organ injury caused by NO,SOD and MDA level and alleviated the damage of body.

Objective To study the effect of granulocyte-macrophage colony-stimulating factor(GM-CSF)on angiogenesis of rat with acute myocardial injury induced by isoproterenol(Iso). Methods A total of 60 adult male Wistar rats were randomly divided into 3 groups: normal control group, GM-CSF pretreatment group (GM-CSF group), and lso injury group, 20 rats in each group. GM-CSF group was administered recombinant human(rh)GM-CSF(5.0 μg/kg), through tail intravenous injection once a day for three days. Then the GM-CSF group and the Iso injury group were anesthetized by intraperitoneal injection of lso( 15.0 mg/kg) once a day for three days. The same dose of saline was administered in the same way to the control rats. Ten days after injection, pathological changes of myocardial damage and infarct area were examined by immunohistochemistry. The mRNA expression levels of polypeptide antigen (CD34), vascular endothelial growth factor (VEGF) and its receptor KDR/flk- 1 were measured by RT-PCR. Results The difference of myocardial necrosis area between groups was statistically significant(F=10.07, P < 0.01), in which GM-CSF group[(37.37 ± 12.98)%] was significantly less than Iso injury group[(45.51 ±14.96)%, P < 0.05]. The difference of myocardial neovascularization density index of rats between groups was statistically significant ( F = 25.54, P < 0.05 ), in which GM-CSF group [(3980.05 ± 477.22) No/mm2] was significantly higher than Iso injury group((2605.93±361.49)No/mm2,P<0.01).The differences of myocardial CD34,VEGF,KDR/flk-1 mRNA expression between groups were statistically significant(F=17.83,4.29,4.10,all P<0.01).Compared to Iso mjury group[CD34(23.85±6.06),VEGF(31.80±8.05),KDR/flk-1(30.16±8.01)]were higher in the GM-CSF group[CD34(44.04±10.13),VEGF(49A±11.59),and KDR/flk-1(46A9±7.90),all P<0.01].The expressions of myocardiM VEGF mRNA and its receptor KDR/flk-1 mRNA was positively correlated(r=0.725,R2=0.526,P<0.01).Conclusions GM-CSF prelreatmcnt increases the density ofnew blood vessels in myocardium,and reduces the Iso-induced myocardial injury in rats.

Objective To introduce our experience in embolizing cerebral ruptured-aneurysms of elderly patients in our hospital. Methods Totally 76 elderly patients were referred to our hospital due to ruptured-aneurysms.81 aneurysms were confirmed by DSA,all of them were sac aneurysms,among which 75 cases (body/neck≥ 1) were treated with balloon-assisted coiling,29 narrow-necked (body/neck≥2) aneurysms and 30 wide-necked (1 ≤ body/neck＜ 2) aneurysms were treated with balloon-assisted coiling successfully,but 6 narrow-necked (body/neck≥2) were treated with balloonassisted coiling in emergency,followed by a stent-assisted coiling in secondary embolization,4 cases with body/neck＜1 were treated with stent-assisted coiling technique in emergency,2 non ruptured aneurysms could not be treated.The times of balloon dilation were (2.1 ± 1.3),single expansion of filling was (33.4±14.1)s. Results The arterial thrombosis happened in two patients (2.7 ％),two aneurysms ruptured (5.3％) during the procedure. No stent-related thrombosis happened. 86were elevated as good,8 as serious according to the Glasgow outcome scale,neither died after operation or delayed thrombosis or infarction lesion during following up. Conclusions Balloonassisted coiling is a safe and effective method in elderly patients during acute stage of rupturedaneurysms.

Objective To investigate the effect of ultrasound-guided subcostal transverses ab-dominis plane block with dexmedetomidine mixed ropivacaine in related-living kidney transplantation donor.Methods Forty related living kidney transplantation donors (male 1 5 cases,female 25 cases, aged 20-60 years,ASA grade Ⅰ or Ⅱ)were randomized into dexmedetomidine group (group D,n =20)and control group (group C,n =20).All the patients received ultrasound-guided subcostal TAP block after operation,group D with dexmedetomidine 1 μg/kg and 0.375% ropivacaine to 20 ml,and group C with 0.375% ropivacaine 20 ml.All the patients were assessed with both Ramsay scores and Visual Analogue Scale (VAS)at rest or on moving at 2,4,8,24 and 48 hours after operation.The duration of sensory blockade,the first time and the times of pressing the analgesia pump in the first 24 hours after operation,the requirements of flurbiprofen axetil and midazolam were recorded.The u-rine on the first and the second day after operation and the first flatus time were compared.The plas-ma concentrations of urea nitrogen (BUN)and creatinine(Cr)before surgery and on the second and fifth day after operation were determined.Results Compared with group C,the scores of VAS were de-creased at 4 and 8 hours after operation in group D (P <0.05).There were no differences in Ramsay scores between the two groups.Compared with group C,less frequency of use of flurbiprofen axetil (15% vs 0%) and midazolam (10% vs 0%)in group D,longer time of sensory blockade,postponed time to firstly press the analgesia pump and the less frequency of pressing the analgesia pump in group D (P <0.05),the urine on the first day was increased and the first flatus time was earlier,the plasma concentrations of BUN and Cr were significantly lower on the second day after operation in group D (P < 0.05 ). Conclusion Dexmedetomidine mixed ropivacaine can promote the anaesthesia of ultrasound-guided subcostal TAP block with ropivacaine,prolong the time of sensory blockade and improve the recovery after nephrecto-my in living-related kidney donor.

Objective To elucidate the effect of community nurse-led self-efficacy intervention on selfmanagement behaviors of hypertension in community elderly.Methods In this study,non-equivalent control group was designed,78 community elderly patients with hypertension were selected in the two community health service centers and divided into intervention group (38 cases) and control group (40 cases).The intervention group was treated with self-efficacy intervention for 3-month,and control group did not take any interventions.The “chronic disease self-management behavior measurement" (Stanford University research tool) and the measure of physical intervention study were used to valuate the effect of interference before and 3 months after intervention.Results Systolic blood pressure in intervention group was (5.11 ± 12.30) mm Hg and (0.33 ±4.64) mm Hg in control group,the difference was statistically significant ( t =2.248,P ＜ 0.05 ).BMI in intervention group was reduced by (0.43 ± 0.42 ) kg/m2,however,in control group was increased by ( 0.39 ±1.26) kg/m2,the difference has reached the statistical significance ( t =3.825,P ＜ 0.01 ).Self-efficacy,selfmanagement,health state in two groups were different ( P ＜ 0.01 ).Other factors in scale did not reach statistical significance in health service utility in two groups ( P ＞ 0.05 ).Conclusions The self-efficacy intervention can significantly enhance the community' s self-efficacy in elderly hypertensive patients,improve self-management behaviors and health,reduce health service use for a certain effect,but long-term effects need to be observed.

Objective To analyze clinical features of patients with chikungunya fever and provide future reference for prevention and control of the disease. Methods Forty-six confirmed chikungunya fever inpatients were included. Their clinical symptoms, signs, blood count, key biochemical indicators and treatments were analyzed. The comparison between groups were done by ttest. Results The percentages of total cases presenting with fever, rash and joint pain were 100. 0% (46/46), 91. 3% (42/46) and 89. 1% (41/46), respectively. Fifteen (32.6%) cases displayed leucopenia. Increases in lactose dehydrogenase (LDH) and creatine kinase (CK) were observed in 45. 5%(20/44) and 28. 9%(13/45) of the cases, respectively. Three cases displayed an increase of alanine aminotransferase (ALT). Administration of ribavarin extend febrile time compared to symptom-relieving treatments (t=2. 588, P = 0. 013). Conclusions Clinical features of chikungunya fever include fever, rash and joint pain. Good prognosis can be resulted from symptom-relieving treatment. Antiviral treatment may not be beneficial to reducing course of disease.

Objective To investigate the association of excessive daytime sleepiness(EDS) and the quality of life in patients with moderate to severe obstructive sleep apnea and hypoventilation syndrome (OSAHS).Methods 123 patients with moderate to severe OSAHS were diagnosed by polysomnography(PSG),and 52 cases ruled out by PSG were controls.Patients and controls were completed the Calgary sleep apnea quality of life index (SAQLI) and the Epworth sleepiness score(ESS).Results There were statistical significance of body mass index (BMI),respiratory disturbance index(RDI),the lowest oxygen saturatioo( LSpO2 ),the longest apnea time( Tmax),the percentage of recording time with oxygen saturation of 90％ or less(T90) between the patients and the controls.Daily Functioning,Social Interactions,Emotional Functioning,Symptoms,and total scores of SAQLI in patients with moderate to severe OSAHS were(3.88 ± 1.05),(4.48 ± 1.39),(4.76 ± 1.59),(2.98 ± 1.10),(3.94 ± 1.22),which were less than that of controls respectively.The ESS scoree of patients with moderate to severe OSAHS were higher than that of controls[ ( 13.98 ± 4.05 ) vs (5.78 ± 2.45) ],( P ＜ 0.01 ).ESS were related to the daily Functioning,social interactions,emotional functioning,symptoms,and total scores of SAQLI in patients with moderate to severe OSAHS,and the coecient of correlation were - 0.52,- 0.48,- 0.40,- 0.48 and - 0.44,respectively,and all p value were less than 0.01.Conclusion Patients with moderate to severe OSAHS have the EDS,which associate with the impairment of quality of life.The higher ESS may indicate the decrease of quality of life in patients with moderate to severe OSAHS.

ObjectiveTo explore clinical characteristics and diagnosis of patients with granulocytic sarcoma (GS),and to evaluate the value of FCM in diagnosing it.MethodsClinical data of one patient with GS was reviewed and related literature was reviewed. ResultsThe patient was diagnosed as AML-M2,chromosomal karyotype was 46.XY, t (8;21)(q22;q22)and the AML/ETO gene was positive. Systemic chemotherapy with daunorubicin plus cytarabine was given and complete remission was received. Then a nodular in medial angle of right eye was found. Result of CT indicated the possibility of leukemia infiltration.Needle aspiration cytology was conducted and many blast cells were found by microscope.CD34+ CD117+ CD13+ CD33+CD45dim SSC+ can be found by FCM. The cytology was complete remission and minimal residual disease was negative. Finally diagnosis was GS, relapse of AML. After a systemic chemotherapy with large dose of cytarabine plus teniposide (cytarabine 6.0 g/d, d1-3;teniposide 50 mg/d, d1-3), the mass could not be touched and the follow-up was continued.Conclusion Although relapse of AML often occurs in the testicle or the central nervous system,it pay attention to the possibility of relapse of AML presenting as GS.Fine needle aspiration cytology(FNAC)combined with FCM can provide an convenient, handy, practicable and less invasive way of the diagnosis and can be a preferred detection technique.
