Chinese Pharmacological Bulletin 2003;0(10):-
Aim To study the protective effects of curcumin on myocardial reperfusion injury in rats.Methods Myocardial ischemia reperfusion injury model was established through occluding the left anterior descending branch of coronary artery for 60 min and removing the ligation later to reperfuse for 30 min in vivo.Different doses of curcumin were administered through intravenous injection 5 min before the onset of ischemia.The changes of hemodynamics were recorded and myocardial infarct sizes were measured.Results Curcumin(20,40 mg?kg~(-1))improved the hemodynamics during myocardial ischemia reperfusion in a dose-dependent manner,as shown by the significant increase in LVSP and?dp/dt_(max) and the decrease in LVEP.Moreover,curcumin reduced the myocardial infarct sizes.Conclusion Curcumin exerts protective effects on myocardial ischemia reperfusion injury.

Academic Journal of Second Military Medical University 2010;28(12):1375-1377
Objective: To establish a human lung squamous carcinoma cell line and to study its biological characteristics. Methods: Lung squamous carcinoma specimens were freshly resected during operation; the tissues were incubated in vitro and the cell line was named CHLH-1. The biological characteristics of the cells were studied by light microscopy, electron microscopy, chromosome analysis and transplantation experiment. Results: Cells from the specimens of the primary tumor, the CHLC-1 cell line and the cells from transplanted tumor possessed the characteristics of malignant squamous epithelium under light and electron microscope. The cell growth curve, doubling time and mitotic index were also observed in vitro. Nuclear chromosome analysis revealed that the tumor was a subtriploid with a mode of 60-68 per cell. Tumor nodes were observed under the skin of nude mice by heterogenic transplantation. Conclusion: The characteristics of the established cell line suggest that it is a newly established human squamous carcinoma cell line.

Objective To survey symptom occurrence degree of maintenance hemodialysis (MHD) patients,and its related factors,and to provide a basis for clinical symptom management. Methods A total of 142 MHD patients were selected with convenience sampling method from a hospital in Ningxia from July 2015 to September 2015 and investigated with the Dialysis Symptom Index ,the Pittsburgh Sleep Quality Index and the family Adaptation,Partnership,Growth,Affection and Resolve(APGAR)Scale. Results The occurrence rate of various symptoms ranged from 53.5%to 92.3%. Fatigue(92.3%),itching(86.6%)and dry skin(85.9%)were the top three prevalent symptoms. Fatigue (30.3%),difficulty falling asleep (27.5%),hyposexuality (27.5%) and trouble in sleeping deeply(27.5%)were the most serious symptoms.Multivariate linear regression analysis showed that gender,nationality,sleep quality,combining with hypertension and arrhythmia had significant influence on the occurrence degree of symptom in MHD patients(P < 0.05). Conclusion Symptoms in MHD patients are preva-lent. Efficient symptom management should be performed to improve the quality of life of MHDpatients.

Objective To investigate the protective effects of fluvastatin(Flu) on rat renal fibroblasts proliferation and cytokines expression induced by cyclosperine A (CsA). Methods The fibroblasts were cultured with CsA or with CsA plus fluvastatin. The cellular proliferation was determined by MTT colorimetry. The mRNA expression of transforming growth factor β1(TGF-[β1), connetive tissue growth factor (CTGF) and c-fos was detected by BT-RCB. The protein level of flbronecfin (FN) was measured by Western blotting. Results CsA inhibited the proliferation of fibroblasts in dose- and time-dependent manner (P<0.05). Treatment with Flu accelerated the suppression of fibroblasts resulted from CsA (P<0.O1). CsA stimulated the expression of TGF-β1, CTGF, c-fos and FN compared with control group(P<0.05), which could be down-regulated by Flu (P<0.05). Conclusion Fluvastatin may relieve CsA-induced nephrotoxicity in rat fibroblasts.

OBJECTIVETo investigate the inhibitory effect of bone marrow mesenchymal stem cells (BMSCs) on E coliinduced prostatitis in rats.
METHODSBMSCs were isolated, cultured and amplified by the attached choice method. Fifty SD rats were randomized into five groups of equal number: normal control, acute bacterial prostatitis (ABP) , chronic bacterial prostatitis (CBP), ABP + BMSCs, and CBP + BMSCs, and the animals in the latter four groups were injected with E. coli into both sides of the prostate under ultrasound guidance for 1 - 14 days to induce ABP and for 4 - 12 weeks to induce CBP. The control rats were injected with the same amount of PBS. Two weeks after injection of BMSCs into the prostates, pathomorphological changes in the prostate were observed under the light microscope and the mRNA and protein levels of IL-1β and TNF-α determined by RT-PCR and ELISA, respectively, followed by statistical analysis with SPSS 18.0.
RESULTSHistopathological evaluation showed typical pathological inflammatory changes in the prostates of the rats in the ABP and CBP groups, including glandular structural changes, interstitial edema, inflammatory cell infiltration, and fibrous hyperplasia, which were all remarkably relieved after treated with BMSCs. The mRNA and protein levels of IL-β ([0.829 ± 0.121] and [271.75 ± 90.59] pg/ml) and TNF-α ([0.913 ± 0. 094] and [105.78 ± 19. 05] pg/ml) in the ABP and those of IL-1β ([0. 975 ± 0. 114] and [265. 31 ± 71. 34] pg/ml) and TNF-α ([0. 886 ± 0. 084] and [107. 45 ± 26. 11 ] pg/ml) in the CBP groups were significantly higher than those in the control rats ([0. 342 ± 0.087] and [45.76 17. 99] pg/ml, P <0. 05); ([0.247 ± 0.054] and ([19.42 ± 7. 75] pg/ml, P <0. 01) as well as than those in the ABP + BMSCs ([0. 433 ± 0. 072] and [51. 34 ± 22. 13] pg/ml, P < 0. 05 ) ; ( [0. 313 ± 0. 076] and [28. 38 ± 8. 78] pg/ml, P < 0. 01) and the CBP + BMSCs group ([0.396 ± 0.064] and [56.37 ± 21.22] pg/ml, P <0.05); ([0.417 ± 0.068] and [29.21 ± 10.22] pg/ml, P <0.01).
CONCLUSIONInjection of BMSCs can reduce E coli-induced prostatic inflammation reaction, which.may be associated with its reduction of inflammatory cell infiltration and the expressions of IL-1β and TNF-α in the prostate tissue.

Objective To detect the level of serum α-klotho in different obese people and to investigate the correlation between serum α-klotho and obesity-related glomerulopathy (ORG).Methods A total of 48 cases of ORG diagnosed by renal biopsy were enrolled in the study.Fortyeight gender-,age-and BMI-matched obese participants,and 48 obese chronic kidney disease (CKD) patients without ORG were included as controls.The clinical manifestations,laboratory examinations of all three groups were collected,and the level of serum α-klotho protein was measured by ELISA.Results The patients with ORG were characterized by decreased serum α-klotho concentration compared with obese patients group and obese CKD patients group [572.66(439.92,690.58) pg/ml vs 635.85(559.52,769.20) pg/ml and 690.30(516.15,828.20) pg/ml,P< 0.01].Multinomial multiple logistic regression analysis revealed that serum α-klotho (per 100 pg/ml increased) was independently associated with the prevalence of ORG,and the risk of ORG decreased by 35% in the obese participants (OR=0.652,95% CI:0.487-0.872) and 38% in CKD patients (OR=0.617,95% CI:0.453-0.832) respectively.Conclusions The level of serum α-klotho is significantly decreased in ORG and associated with the prevalence of ORG independently.Serum α-klotho may be a protective factor for ORG.
