OBJECTIVETo observe the effect of external application of Zhuangshenling Recipe (ZR) combined with Western medicine (WM) on the heart function of chronic heart failure (CHF) patients of Xin-Shen yang deficiency, interior retention of water-fluid syndrome (XSYDIRWFS).

METHODSTotally 140 CHF patients of XSYDIRWFS were randomly assigned to two groups, the treatment group and the control group, 70 in each group. All patients received WM therapy. Those in the treatment group were applied with ZR at Xinshu (BL15) and Shenshu (BL23), while those in the control group were applied with placebos at Xinshu (BL15) and Shenshu (BL23). The therapeutic course for all was 12 weeks. The integrals of TCM syndrome, grading of cardiac function, brain natriuretic polypeptide (BNP), and 6 min walking distance were observed before and after treatment.

RESULTSAfter twelve weeks of treatment, the effective rate of improved grading of cardiac function, the total effective rate of TCM syndrome efficacy, and the BNP level were obviously better in the treatment group (P < 0.05). There was no statistical difference in 6 min walking distance between the two groups (P > 0.05).

CONCLUSIONExternal application of ZR combined with WM could improve the heart function of CHF patients of XSYDIRWFS.

Objective To study the effect of antiapoptosis factors PED/PEA-15 and XIAP on prostate cancer cells(PC-3)apoptosis.Methods The expressions of XIAP and PED/PEA-15 in prostate cancer cells(PC-3)were respectively assayed using the RT-PCR technique.XIAP and PED/ PEA-15 specific siRNA vectors were designed and constructed and then were transiently cotransfected into PC-3 cells under induction of liposome.The effects of siRNA vectors on PED/PEA-15 and XIAP transcription were assayed by RT-PCR technique,and the effect of XIAP and PED/PEA-15 on cancer cell apoptosis were determined by flow cytometry and microscope observation.Results PED/PEA- 15 and XIAP were both highly expressed in PC-3 cells.Enzyme digestion analysis and DNA sequencing confirmed that the PED/PEA-15 and XIAP-specific siRNA expression vectors were constructed successfully.The designed siRNA sequences of PED/PEA-15 and XIAP could specifically inhibit their transcription.The PC-3 cells which were cotransfected with PED/PEA-15 and XIAP- specific siRNA vectors were more sensitive to doxorubicin.The apoptosis rate of cotransfected cells was significantly increased.Conclusions PED/PEA-15 and XIAP might be involved in the development of prostate cancer.

Objective:To prepare the polyclonal antibodies against advanced oxidation protein products (AOPP),and to provide an effective agent for research on the pathogenesis of AOPP and assess exactly the relationship between AOPP and relative diseases.Methods:AOPP-rabbit serum albumin (AOPP-RSA) was prepared by treating RSA with hypochloric acid.The rabbit anti-AOPP-RSA polyclonal antibodies were generated and purified by affinity chromatography. The titers and the specificity of the antibodies were measured by ELISA.The plasma AOPP and the localization of AOPP in nephridial tissues of some patients with chronic kidney disease (CKD) were determined using rabbit anti-AOPP-RSA.Results:Titers of the antibodies were 10-6.Purified antibodies reacted specifically with oxidized albumin from different genus,but could not react with normal albumin and glycosylated albumin.The high level of AOPP in plasma from CKD patients was confirmed by Western blot.The antibodies could be used to immunostain AOPP deposition in different regions of kidney tissues from both CKD patients and CKD rat models.Conclusion:We successfully generate rabbit anti-AOPP polyclonal antibodies with high titers and striking specificity.The presence of plasma AOPP and localizations of AOPP in kidney tissues of CKD patients can be demonstrated using the antibodies.The development of anti-AOPP polyclonal antibodies may provide a new tool to explore the pathogensis of AOPP and assess exactly the relationship between AOPP and relative diseases.

Objective To examine the effects of benazepril and losartan on glomerular podocyte autophagy in aged spontaneously hypertensive rats (SHRs) and investigate the underlying mechanisms of renal-protective effects of angiotensin-converting enzyme inhibitors (ACEI)/angiotensin receptor blockers (ARB).Methods Wistar-Kyoto rats (WKYs) were used as the normal control (NORM) group (2 ml physiological saline per day).SHRs were randomly divided into 4 groups:the CTRL group (2 ml physiological saline per day),the ACEI group (10 mg · kg-1 · d-1),the ARB group (30 mg· kg-1 ·d-1) and the combined group (10 mg· kg-1 · d-1 benazepril and 30 mg· kg-1 · d-1),with six 18-month-old make rats in each group.The experiments were conducted during a 4-month period.Blood pressure was monitored regularly.At the end of the experiments,we measured the levels of urine protein,urine creatinine,serum creatinine (SCR),blood urea nitrogen (BUN),and serum and renal cortex angiotensin Ⅱ (AngⅡ).Ultrastructural changes in the kidney were examined under light and transmission electron microscopy.The expressions of nephrin,LC3BⅡ,Atg5 and p62 in the glomerulus were analyzed by Western blot analysis.Results After treatment,the blood pressure and the urine albumin/creatinine ratio of the four SHR groups were still significantly higher than those of the NORM group,but the blood pressure and the urine albumin/creatinine ratio of the ARB group and the combined group were significantly lower than those of the CTRL group (all P＜ 0.05);There were no significant differences in SCR and BUN levels among these five groups (P＞ 0.05);The level of serum AngⅡ of the combined group was significantly higher than that of the CTRL group [CTRL (0.08±0.00) μg/L,Combined (0.12±0.01) μg/L,P＜0.05];The levels of cortex AngⅡ of the four SHR groups were significantly lower than those of the NORM group,while the level of cortex AngⅡ of the ARB group was significantly higher than that of the CTRL group (all P＜0.05);Renal ultrastructural examination revealed shrunken glomeruli,fused or effaced epithelial cell foot processes,and focal atrophy of renal tubules in the four SHR groups.These pathological changes were more serious in the CTRL group but less so in the combined group.There were significantly more autophagosomes in the NORM group and the combined group than in the CTRL group (P＜0.05).Compared with the NORM group,the expressions of nephrin,LC3BⅡ,Atg5 and p62 in the CTRL group were suppressed significantly (P ＜ 0.05).The expressions of nephrin,LC3BⅡ and Atg5 in the ACEI group and the expressions of nephrin,LC3BⅡ,Atg5 and p62 in the ARB group and the combined group were higher than in the CTRL group (P＜0.05).Conclusions ACEI/ARB can decrease the autophagic activity of glomerular podocytes.The renal-protective effects of ACEI/ARB may be mediated by glomerular podocyte autophagy,which is induced by AngⅡ.

BACKGROUND:In previous experiments, we have confirmed that platelet rich fibrin has the ability of osteoinduction, and have conducted a preliminary study on its microstructure and biomechanics. However, little is reported on its histology research.
OBJECTIVE:To compare the histological changes after implanting platelet-rich fibrin, Bio-Oss and autologous bone and to analyze the pros and cons of platelet-rich fibrin implantation for repair of bone defects.
METHODS: As previously reported, animal models of critical bone defects were established respectively on the bilateral femoral condyles of 12 beagle dogs. Then, platelet-rich fibrin, Bio-Oss+colagen membrane (Bio-Oss group) and autologous bone (autologous bone group)+colagen membrane were respectively implanted. At 3, 6, 8 and 12 months, one experimental dog from each group was kiled, respectively, and histological observation was performed. Another beagle dog as blank control was enroled to establish the animal model of critical bone defects, with no implantation.
RESULTS AND CONCLUSION:At 3, 6, 8 and 12 months after implantation, there were significant differences in the new bone formation speed and amount between the platelet-rich fibrin group, Bio-Oss group and autologous bone group. These three kinds of bone grafts al had osteoinductive ability to different extents. In the platelet-rich fibrin group, the osteogenic effects were better at 3 and 6 months, and the new bone was similar to natural one; in the autologuos bone group, bone necrosis was noticeable at 3 and 6 months, but the osteogenic effects became better at 8 months, and the new bone was similar to natural one at 12 months; in the Bio-oss group, the osteogenic effects were similar to those in the platelet-rich fibrin group, but the residual of Bio-oss was visible at 12 months; in the blank control group, no bone formed at 3 months, indicating the animal model of critical bone defects was made successfuly. In brief, the platelet-rich fibrin has good osteoinductive ability, with shorter time and better quality.
