Objective To study the effect of post-hospital nursing intervention on blood pressure and medication compliance of hypertensive patients.Methods One hundred hypertensive patients were divided into the observation group and the control group in equal number by the random digits table.Those in the control returned regularly for consultations and took medicine under doctor’s supervision and those in the observation group received out-of-hospital nursing intervention apart from the nursing done to the controls. The blood pressure and medicine-taking compliance were assessed in 6 months.Result The observation group was significantly better than the control one in terms of blood pressure and medicine-taking compliance(both P<0.05).Conclusion The post-hospital systematic nursing intervention may help to control the blood pressure of hypertensive patients and enhance their medicine-taking compliance so as to improve the curative effect.

Objective To evaluate the applied values of susceptibility weighted imaging (SWI) in acute ischemic stroke.Methods Totally 40 patients with acute ischemic stroke were included within 72 hours after symptom onset.They adopted multimodal magnetic resonance imaging examination,including regular magnetic resonance imaging sequence (T1WI,T2WI),time of flight MR angiography (TOF-MRA),diffusion weighted imaging (DWI) and susceptibility weighted imaging (SWI).Furthermore,12 of the 40 patients received dynamic susceptibility contrast enhanced perfusion weighted imaging (DSCPWI) examination.Results Of the 40 patients,12 ones had positive results for multiple lesions of cerebral microbleeds (CMBs) by SWI,and the detection rate was 30％.There were 24 patients showed susceptibility vessel sign (SVS) in SWI,and the susceptibility rate was 60％.In the 12 patients received DSC-PWI examination simultaneously,there were 7 cases had the anomaly range by SWI larger than that by DWI while similar to that by DSC-PWI.Conclusion SWI can show SVS and CMBs clearly,estimate ischemic penumbra,know intracranial conditions completely and supply reliable basis for individualized treatment.

Objective To study the characteristics of immune function,Epstein-Barr virus(EBV) antibodies and EBV-DNA in children with different clinical types of EBV infection,which provide basis for prevention and treatment of EBV infection.Methods Clinical data of 103 patients suffering from EBV infection were retrospectively analyzed in Xijing Hospital of the Fourth Military Medical University.A total of 103 children were divided into infectious mononualeosis(IM) group(n=68),chronic active Epstein-Barr virus infection(CAEBV) group(n=13) and Epstein-Barr virus-related hemophagocytic lymphohistiocytosis(EBV-HLH) group(n=22).The changes of EBV antibodies,EBV-DNA,immunoglobulin levels,lymphocyte subpopulation and complement series were detected and compared among the three groups.A total of 26 healthy children at the same stage were enrolled as a control group,immunoglobulin levels,lymphocyte subpopulation and complement series were detected in control group,then compared with the rest of the three groups.Results The levels of C3 and C4 in CAEBV group and EBV-HLH group were significantly decreased than those in the control group(P<0.05).The levels of IgA,IgG and IgE in EBV-HLH group,CAEBV group,IM group and control group gradually increased(P<0.05,respectively).The levels of IgA,IgG and IgE in EBV-HLH group and CAEBV group significantly decreased than those in control group(P<0.05,respectively).The levels of IgA,IgG and IgE in IM group decreased than those in control group,while there were no statistically significant differences(P>0.05).CD8+T cells in IM group significantly increased than those in the rest of the three groups(P<0.05,respectively).T cells,CD8+T cells,CD4+ T cells,CD4+/CD8+ ratios,NK cells,B cells of EBV-HLH group significantly decreased than those in the rest of the three groups(P<0.05).The positive rates of EBV antibodies in CAEBV group and IM group were significantly higher than those in EBV-HLH group(P<0.05).EBV-DNA in EBV-HLH group were significantly higher than those of CAEBV group and IM group(P<0.05).Conclusion EBV-DNA levels in the serum are positively correlated with disease types and severity,the pathogenesis of IM,CAEBV and EBV-HLH induced by EBV infection are associated with immune dysfunction.Dynamic monitoring of EBV load and cell immune function can reflect disease status and progress risk.

To probe the effect of paeoniflorin on periovular granuloma and liver fibrosis in mice infected with Schistosoma japonicum in different times of infection and the treatment with praziquantel (PZQ). The models of hepatic fibrosis induced by S.japonicum were established by exposure of BALB/c mice percutaneously through the tail to cercariae of S.japonicum. and mice with treatment were randomly divided into 3 groups: i.e. groups of pre-treatment (I), group of simultaneous treatment (Ⅱ) and group of post-treatment (III). All groups, except the normal control group, were orally introduced with PZQ. And mice in the paeoniflorin-treated group and control group were separately introduced with paeoniflorin and 0.5% sodium carboxymethycellulose respectively. The treatments in group I, II and III were started 30 days before PZQ usage, simultaneously with PZQ or 30days-after PZQ usage respectively. Mice in these groups were sacrificed on the 102, 132 or 162 days after infection. Then the serum levels of hyaluronic acid (HA), amino-terminal peptide of type III procollagen (PIIIP) and liver hydroxyproline (Hyp) were detected. The histopathology was examined by HE and Masson staining; the degree of hepatic fibrosis and the area of egg granuloma were analyzed. The expression of collagen I was examined by immunohistochemical method. It was found that the area of granuloma and degree of hepatic fibrosis in the paeoniflorin-treated groups in group I and III were significantly lower than those in the model control groups. Also, paeoniflorin could induce decreas expression of collagen I. Meanwhile the levels of serum HA, PIIIP and liver Hyp were all reduced in comparison with those in the control group (P<0.05 or P<0.01). However, in group Ⅱ, no significant difference was noted between the treated and the control group in most data. Paeoniflorin also showed the effects to reduce the size of periovular granuloma and to reduce the expression of type I collagen, thereby to resist the development of hepatic fibrosis caused by S. japonicum.-It is evident that PAE shows an efficaciously therapeutic effect on the development of liver fibrosis of shistosomiasis, whenever it is administered before or after the usage of schistosomicides.

A high-throughput method for screening drug multi residues was developed by quadrupole-time-of-flight( Q-TOF) mass spectrometry together with QuEChERS sample preparation technique. It has been used for the determination of 57 drugs, such as tetracyclines ( TCs ) , sulfonamides ( SAs ) , quinolones ( QNs ) , triphenylmethanes (TPMs), estrogens (ETs), androgens (AGs) and glucocorticoids (GCs) in fish. The optimized pretreatment conditions were examined. The target compounds were extracted with acetonitrile under the condition of Na2 EDTA-Mcllvaine buffer, and the usage of clean-up reagents was 25 mg anhydrous magnesium sulfate, 12. 5 mg octadecylsilane and 6. 25 mg N-Propylethylenediamine sorbent for extracted solvent of each milliliter. The positive results acquired by this high-throughput method were confirmed by liquid chromatography-tandem mass spectrometry ( LC-MS/MS) . The detection limit for these 59 drugs was in the range of 0. 5-5. 3 μg/kg. The method is time-saving, convenient, effective and wide coverage. Its sensitivity can meet the requirement of the detection of drug residues in aquatic products.

Objective To investigate the relationship between the Plasmodium malaria titre with the body temperature and prog-nosis to provide a theoretical basis for malaria diagnosis and missed diagnosis.Methods Ninety-three malaria test positive speci-mens were collected and simultaneously performed the plasmodium test by using the colloidal gold immune chromatography assay and thick film blood slide.The body temperature of malaria patients was recorded ,and the malaria test was conducted once when the body temperature was increased by 1 ℃ until positive for malaria detection.Results In 93 tested specimens ,the infection rate of Chinese was 56.98% (53/93) ,and which of foreigners was 43.01% (40/93) ,the difference between Chinese and foreigners malaria infection groups had no statistical significance ,showing that malaria infection had no relationship with race.Among 93 specimens , the initial malaria infection was in 48 cases ,including 47 Chinese and 1 foreigner ,and 45 cases had twice or more malaria infection , in which 33 cases had the titers of 1:10 ,with the recurrence rate of 0.09% (3/33) and the re-burning rate was 0.27% (9/33). The titer of 1:20 had 28 cases ,with the recurrence rate 0.04% (1/28) ,and the burning rate 0.21% (6/28).Titer of 1:30 was 19 people ,with the recurrence rate 0.16% (3/19) and the burning rate 0.37% (7/19).The titer of 1:40 was 13 people ,with the re-currence rate 0.15% (2/13) ,and the re-burning rate of 0.38% (5/13) ,there was no statistically significant difference between the number of recurrent and re-burning patients with the titre(χ2 =2.5 ,P>0.05 ;χ2 =1.96 ,P>0.05).Conclusion There is a positive correlation between malaria with the titer and temperature.The titer is elevated ,and the probability of recurrence and re-buring is increased.

PurposeAdult intussusception is rare, and clinical symptoms are atypical and tend to be misdiagnosed. This study aims to explore the imaging features of intussusception on multi-slice CT (MSCT) and to improve the diagnosis of this disease. Materials and Methods Sixty cases with intussusception conifrmed by pathology were recruited and imaging ifndings including sleeve head lesions, set sheath canal, exhumation of intestine, involved mesenteric fat, and blood vessels were retrospectively analyzed. Results The direct sings included 60 cases with target signs, 44 of them with single target signs and 16 of them with double target signs; the shape was kidney like in 39 cases and irregular in 21 cases; 22 cases showed double intestinal signs, 15 cases showed comet tail signs, and 25 cases showed mountain like with different direction. The indirect signs included 60 cases with thickened intestinal wall and 45 cases with mesenterium fat and vessel in enteric cavity, 12 cases with adjacent mesenteric mass and enlarged retroperitoneal lymph nodes, 15 cases with ascites, 7 cases with metastatic tumors, including 4 cases of liver metastasis, 2 of pelvic ossiifcation metastasis, and 1 of multiple organ metastasis, 1 case combined with renal calculus and 3 case with ureteral caluli. Conclusion There are some special CT manifestations of adult intussusception. Mountain like sign with different direction at the tail is one of the characteristics. CT plays an important role in clinical procedure.

To explore the action target of praziquantel (PZQ) and its underlying mechanism of action, adult male worms of Schistosoma japonicum were collected from the hepatic vein of Kunming mice infected at least 6 or more weeks previously with single-sex cercariae of S.japonicum by perfusion method. These worms were subjected to the action of calcium channel blockers (CCBs) or actin depolymerizing/stabilizing agents interfering with function of the calcium channel. The adult male worms in DMEM culture medium were co-cultivated with near-lethal dose of PZQ(14 μmol/L) overnight(16 hours).Then, the parasites were washed 3 times with sterile physiologic saline next morning after cultivation, re-suspended in new and drug-free medium and then observed under stereo-microscopy during the following 5 days. The experimental results showed that majority of adult male worms of S.japonicum were killed by the action of PZQ in a dose of 14 μmol/L in vitro under normal condition; while the worms pre-incubated with the actin depolymerizing agent cyto chalasin D (CyD) were able to survive in the condition containing 14 μmol/L of PZQ with a survival rate of 100%, and the worms pre-incubted with CCBs, such as nitrendipine and nifedipineu showed a survival rate of about 50% under the same condition. The results of this study suggest that the calcium channel of Schistosomes may be involved in the action target of PZQ and its underlying mechanism.

Objective To explore high-risk factors that affect the severity of diabetic foot ulcers and the relationship between the severity of diabetic foot ulcers and the general somatic conditions by analyzing clinical data of 218 diabetic foot patients.Methods A retrospective analysis of the clinical data of 218 diabetic foot patients,admitted from 2006 to 2010 was performed.Fasting and postprandial blood glucose ( FBG and PBG ),glycosylated hemoglobin,hemoglobin,serum albumin,serum creatinine,as well as serum urea nitrogen and fibrinogen were determined in patients with different Wagner levels.The effects of peripheral arterial disease,neuropathy,infections and other factors on severity of diabetic foot ulcers,and the prognosis of those patients with different Wagner levels were analyzed.Results ( 1 ) FBG and PBG in Wagner 5 patients were significantly higher than those in Wagner 1,but there was no statistical significance in HbA1C difference.(2) Hemoglobin,total cholesterol,serum albumin in Wagner 5 patients were decreased significantly ; white blood cells,serum creatinine and fibrinogen were increased significantly ( P＜0.01 ).(3) The intima-media thickness(IMT) of femoral artery in Wagner 2-and-above patients was increased significantly compared with that in Wagner 1 ( P＜0.05 ).( 4 ) Logistic regression analysis showed that hemoglobin,fibrinogen,glycated hemoglobin,femoral artery intima-media thickness,and bacterial infection were correlated independently with the severity of diabetic foot ulcers.(5) The hospitalized days were increased with rising Wagner levels ; the prognosis of Wagner 5 patients was the worst,with the highest mortality in the group.Conclusions Changes in blood level of hemoglobin,fibrinogen,along with higher HbA1C and femoral artery IMT,as well as infections are high-risk factors of severity in diabetic foot patients.HbA1C is not a good indicator of blood glucose control in patients with Wagner 5 grade.The higher the Wagner grade,the longer the time spent in hospital,and the worse the prognosis wouldbe.
