Objective:To observe therapeutic effect and influence of rosuvastatin on levels of interleukin (IL)-35 and nu- clear factor-κB (NF-κB)in patients with coronary heart disease (CHD).Methods:A total of 85 CHD patients were randomly divided into rosuvastatin group (n=43,received rosuvastatin calcium therapy based on routine treatment)and atorvastatin group (n=42,received atorvastatin calcium therapy based on routine treatment),both groups were treated for eight weeks all.Cardiac index (CI),cardiac output (CO),left ventricular ejection fraction (LVEF),left ventricular end-diastolic dimension (LVEDd),serum levels of IL-35 and NF-κB,and total effective rate were measured and compared be- tween two groups before and after treatment.Results:Compared with before treatment,there were significant rise in CI, CO,LVEF and IL-35 level,and significant reductions in LVEDd and NF-κB level in both groups after treatment (P<0.05 or<0.01).Compared with atorvastatin group after treatment,there were significant rise in CI [(3.54±0.72)L· min-1 ·m-2 vs.(3.88±0.83)L·min-1 ·m-2 ],CO [(3.78±0.89)L/min vs.(4.94±0.96)L/min],LVEF [(56.20 ±9.71)% vs.(63.48±14.15)%]and serum IL-35 level [(96.26±24.33)pg/ml vs.(106.92±27.26)pg/ml],and sig- nificant reductions in LVEDd [(4.71±0.89)cm vs.(4.36±0.75)cm]and NF-κB level [(21.51±5.01)ng/ml vs. (18.32± 5.17)ng/ml]in rosuvastatin group,P<0.05 all.Total effective rate of rosuvastatin group (95.35% vs. 76.19%)was significantly higher than that of atorvastatin group,P<0.05. Conclusion:Rosuvastatin possesses more sig- nificant therapeutic effect than that of atorvastatin on coronary heart disease,and its heart protection effect besides lipid lowering may be related to regulating levels of interleukin-35 and nuclear factor-κB.

Objective To explore the relationship between the risk of amyotrophic lateral sclerosis (ALS) and exposure to rural environments and pesticide.Methods Studies relevant to rural residence,farmer occupation,pesticide exposure and ALS were identified from the databases including Embase,Ovid Medline,Pubmed,Cochrane Library,Wanfang data,Chinese BioMedical Literature Database,Chinese National Knowledge Infrastructure,China Science and Technology Journal Database up to March 2015.Quality of studies was assessed according to the Newcastle-Ottawa Scale (NOS).Analysis of data and publication bias was performed with software Revman 5.3.Results A total of 24 case-control studies and 3 cohort studies were included into the analysis.The NOS scores of all studies were ≥6.The risk of ALS was associated with pesticide exposure (OR =1.41,95％ CI 1.28-1.56) and farmer occupation (OR =1.42,95％ CI 1.29-1.57),but not associated with rural residence (OR =1.21,95％ CI 0.97-1.51).Subgroup analysis of pesticide exposure and ALS revealed that males (OR =1.75,95％ CI 1.39-2.21) had a higher risk than females (OR =1.53,95％ CI 1.13-2.08),and the risk estimate was higher in studies using E1 Escorial standard (OR =1.68,95％ CI 1.45-1.95) than studies not (OR =1.23,95％ CI 1.08-1.40).The meta analysis had a slight publication bias.Conclusions Our findings support pesticide exposure might increase the risk of ALS.Given that farmers always have high levels of pesticide exposure in their work,they should decrease their exposure level or take proper precautions to lower the risk of ALS.

Objective To observe the influence and safety of rosuvastatin on high sensitive C-reactive protein (hs-CRP),Endothelin-1 (ET-1),N-terminal pro-brain natriuretic peptide (NT-proBNP),pulmonary artery systolic pressure(PASP) and cardiac function in patients with chronic pulmonary heart disease.Methods Eighty patients with chronic pulmonary heart disease were enrolled and divided into the statin group(n =40) and the control group (n =40).All patients were given conventional therapy,while the statin group received additionally rosuvastatin 10 mg/d for 6 months.The control group did not receive any lipid-lowering drugs.The plasma levels of hs-CRP,ET-1,NT-proBNP,liver and kidney functions and creatine kinase (CK),echocardiographic indicators of PASP and right ventricular ejection fraction (RVEF) were measured and compared before and after 6-month treatment.Results The levels of hs-CRP,ET-1,NT-proBNP and PASP were significantly lower after 6-month treatment than before treatment in the two groups (Statin group:hs-CRP:(7.45 ± 1.96) mg/L vs.(20.67 ± 5.12) mg/L,t =9.57,P ＜ 0.01 ; ET-1:(45.72 ± 6.85) ng/L vs.(56.39 ±7.34) ng/L,t =3.78,P ＜ 0.01 ; NT-proBNP:(136.54 ± 20.67) ng/L vs.(182.83 ± 23.27) ng/L,t =4.15,P ＜0.01 ;PASP:(42.6 ± 6.3)mm Hg vs.(52.3 ± 8.4) mm Hg,t =3.54,P ＜ 0.01 ; Control group:hs-CRP:(12.73 ±3.14) mg/L vs.(20.58 ±4.98)mg/L;t =4.96,P ＜0.01 ;ET-1:(51.66 ± 6.42)ng/L vs.(56.43 ±7.81) ng/L,t =3.43,P ＜ 0.01 ; NT-proBNP:(162.74 ± 21.59) ng/L vs.(181.56 ± 22.78) ng/L; t =3.60,P ＜0.01 ;PASP:(45.7 ±6.5) mm Hg vs.(51.8 ± 8.2) mm Hg,t =3.62,P ＜ 0.01),but the statin group reduced even more significantly (t =2.36,2.21,2.25 and 2.09 respectively,P ＜ 0.05).The level of RVEF was significantly higher after 6-month treatment than before treatment in the two groups (Statin group:(50.8 ±7.9) ％ vs.(41.5 ±6.7)％,t =3.69,P ＜0.01 ;Control group:(46.6 ±7.8)％ vs.(42.0 ±6.2)％,t =3.58,P ＜ 0.01),but the statin group increased even more significantly(t =2.18,P ＜ 0.05).Statistical differences of liver and kidney function and serum CK were not found in the two groups before and after treatment(P ＞ 0.05).The adverse reaction in the statin group was few.Conclusion Rosuvastatin can reduce the levels of hs-CRP,ET-1,NT-proBNP and PASP,improve RVEF and cardiac function in patients with chronic pulmonary heart disease,and its security is fine.

Objective To evaluate the efficacy of early rehabilitation for severely burned patients in intensive care unit (ICU).Methods One hundred and eighty two severely burned patients were enrolled in the study,including 97 patients receiving early rehabilitation in ICU (rehabilitation group) and 85 patients without early rehabilitation (control group).There were no significant differences in burned surface area,depth and locations between two groups.After one year's treatment,patients were evaluated by the Vancouver Scar Scale (VSS).Results The mean VSS score of rehabilitation group was significantly lower than that of control group (3.1 ± 1.2 vs.5.2 ± 1.3,P ＜ 0.05).Conclusion Early rehabilitation therapy is beneficial for severely burned patients in ICU.

Secondary lymphoid tissue chemokine (CCL21) is a double-edged sword, which exerts antitumor, anti-infection immune response by binding to the receptor CCR7 on the surface of the multiple immune cells. However, a variety of tumor cells also express the receptor CCR7, the combination of CCL21 with CCR7promotes the invasion and metastasis of tumor cells, leading to the facilitation of tumor development. Therefore,exploring the mechanism(s) of tumor invasion and metastasis might be helpful for use of CCL21 as tumor gene therapy through blocking of CCL21's promotion of tumor invasion and metastasis.

Objective To investigate the change in heat shock protein 70(HSP7O) in the brain tissue of fetal and newborn rats after prenatal hypoxic adaptation and the possible mechanism of the protective effect. Methods Twenty-two 22d pregnant Wistar rats were randomly divided into two groups: GroupⅠ(hypoxic adaptation group) and group Ⅱ(control group). The animals in group Ⅰ were placed in a tightly closed hypoxic adaptation chamber, of which the oxygen and carbon dioxide concentrations were monitored. The pregnant rats were taken out and exposed to fresh air for 5 mm when the 02 % in the chamber was reduced to 15 %, then the pregnant rats were placed back in the chamber and the above process was repeated once. The animals were then left for their natural labor. In control group the pregnant rats underwent the same process but the chamber was not tightly closed(O2 %= 21 %). Prenatal rats were delivered by cesarean section at lb. 3h, 8h, 24h, 48h, 72h, 120h and 168h after hypoxic adaptation and decapitated and brain was removed. Seven newborn rats from each group were decapitated and brain was removed for determination of HSP70 expression with immunohistochimical technique. Results No HSP7O expression was observed in the brain tissue of normal prenatal and newborn rats. HSP70 was observed in the different regions of hippocampus and cortex from 8h to 168h after hypoxic adaptation. Strongest HSP70 expression was observed in hippocampus CAl . Conclusions HSP70 plays a role in the formation of prenatal hypoxic adaptation.

Objective To investigate the CT and MRI features of levamisole induced encephalopathy. Methods The CT and MRI features of 6 cases with clinically proven levamisole induced encephalopathy were retrospectively analyzed. Gd-DTPA enhancement examinations were performed in 5 cases. CT examinations were performed in 4 cases before MRI. Results MRI features: Lesions were mainly located in bilateral periventricular and hypophloeodal white matter, scattered as multifocal lesions, and were different in sizes. Most of the lesions presented as irregular plaques (masses), with round/oval or spotty nodules in second. The lesions had low signal intensity on T 1WI and high signal intensity on T 2WI, and commonly without enhancement. Edema and mass effect were slight. CT features: Two cases showed multiple irregular plaque-sheet low density lesions scattered in bilateral periventricular white matter. One showed symmetrical low density in bilateral putamina nuclei. Another one was negative. Conclusion CT and MRI are valuable for the diagnosis and differentiated diagnosis of levamisole induced encephalopathy. MRI has higher sensitivity and specificity than CT does, and can favorably evaluate the treatment and prognosis.
