Objective To investigate the effect of miR-21 on the secretion of IFN-γ and IL-17 from peripheral blood mononuclear cells (PBMC) in type 1 diabetic patients (T1D). Methods The expression levels of miR-21 in PBMC from 60 T1D patients and controls by quantitative real-time quantitative polymerase chain reaction (qRT-PCR) were detected and the secretions of IFN-γ and IL-17 from T1D PBMC after transfection with miR-21 were detected by enzyme linked immunosorbent assay. Results The expression of miR-21 in PBMC from T1D patients was significantly lower than the control (P<0.01). The levels of IFN-γand IL-17 from T1D PBMC after transfection with miR-21 were remarkably downregulated compared to the control (P < 0.05 or P < 0.01). Conclusion Compared with that at the healthy control group, the expression of miR-21 in PBMC from T1D patients is decreased. MiR-21 could suppress the secretions of IFN-γand IL-17 from PBMC in T1D patients.

Objective To observe the effect of combined administration of Jiang Zhi Tong Luo Soft Capsule(JTSC)and rosu-vastatin on type 2 diabetic with hyperlipemia and its possible mechanisms.Methods Eighty cases of Type 2 diabetic patients with hyperlipemia were divided into combine treatment group (40 cases)and control group (40 cases ).On the basis of routine treat-ment,patients in the combine treatment group were treated by oral 10 mg rosuvastatin (once a day)and oral 100 mg JTSC (three times a day ).Patients in control group were treated by oral 10 mg rosuvastatin (once a day and continuously for 12 weeks).We de-tected the liver function,renal functions,creatine kinase,TC,TG,LDL,HDL and hs-CRP were tested before and after treatments. Results After 12 weeks treatment,the combine treatment group was much better than the control group in reducing the level of TG,TC,LDL,hs-CRP and increasing HDL-C(P <0.05 ).Conclusion Rosuvastatin can effectively treat Type 2 diabetic patients with hyperlipemia.Combined administration of JTSC and rosuvastatin shows better effect than rosuvastatin used alone on the treat-ment of Type 2 diabetic patients with hyperlipemia.

Through the map analysis of various metabolites in rat's urine, the biomarkers in syndrome suitable for Small Qing-Long Decoction (SQLD) were found out, which provided objective basis for the clinical diagnosis and treatment. Based on the rat's urine nuclear magnetic resonance (NMR) spectrum detection of the blank control group, the model group and the SQLD group, the data come from the map by MestRenova pretreatment and integration were analyzed using SIMCA-P+ by (PLS-DA). Then, the corresponding scatter diagram and diagram of loading were re-ceived and the differences of metabolites were found out by the comparison . The results showed that compared with the blank control group, contents of creatinine, guanidinoacetic acid, trimethylamine, taurine, allantoin metabolites in the model group had elevated. And the contents of succinic acid, 2-OG, lactic acid, glycine, methyl nicotine metabolite had decreased. After medication, contents of creatinine, trimethylamine, allantoin, taurine of SQLD group were still higher than the blank control group. However, the contents were reduced compared with the model group. The content of lactic acid was lower than the blank control group, but higher than the model group. There was no statistical significance on changes of guanidinoacetic acid, 2-OG, N-nornicotine. It was concluded that substances found were mainly related to energy metabolism, inflammation and immune resistance, which was especially related to energy metabolism change obviously.

BACKGROUND: The clinical application of one-level osteotomy and multilevel osteotomy has been well documented, but currently few studies were reported to compare their biomechanical characteristics.OBJECTIVE: To investigate the biomechanical characteristics of one-level osteotomy with Dick screw fixation and multilevel osteotomy with Luque instrumentation in the treatment of kyphosis.DESIGN: Randomized comparative experiment.SETTING: Laboratory of the Department of Orthopedics, Renmin Hospital of Wuhan University.MATERIALS: Fresh specimens of thoracic and lumbar spinal segments obtained from 12 3 or 4-year-old calves.METHODS: The experiment was conducted in the laboratory of the Department of Orthopedics, Renmin Hospital of Wuhan University between September 2002 and September 2003. Fresh spinal segments T8-L5 from 12 calves were randomized into an intact group, Dick screw group with one-level osteotomy with Dick screw fixation and Luque group with multilevel osteotomy with Luque instrumentation, with 4 spesimens in each group. Lateral bending test of the specimens was performed to examine the physiological overload using an Instron 5 500 universal material testing machine at the constant speed of 10 mm/minute until fracture or dislocation was induced. Changes in the loading were recorded and the induced injuries observed to obtain the load-displacement curve of the injury test.MAIN OUTCOME MEASURES: The load-displacement curve of the destructive right bending test in each group.RESULTS:All the data of 12 canines were involved in the result analysis.The spinal segments of the intact group yielded to the force of 3 600 N with a flat and smooth load-displacement curve, and those of Dick screw group yielded to a load of 2 800 N with also a relatively flat curve, while in Luque group, the segments did not yield until a load of 7 160 N, followed by drastic decrease of the resistance to less than 4 000 N, generating a flat and smooth curve afterwards.CONCLUSION: Luque instrumentation is a little more preferable than Dick screw in terms of the maximum resistance, but this difference does not justify the clinical decision of their superiority. Both techniques benefit postoperative recovery of spinal function with strong stability.

Objective To evaluate surgical treatment of infected femoral artery pseudoaneurysm.Methods The data on surgical treatment of 45 patients with infected femoral artery pseudoaneurysm admitted from January 2003 to June 2008 were analyzed retrospectively.Fourty-three patients underwent operative treatment including excision of infected femoral artery pseudoaneurysm,exhaustive debridement and bypass graft with vascular prosthesis.Two patients were unavoidable to undergo removing of infected femoral artery pseudoaneurysm and ligating the proximal and distal artery of pseudoaneurysm because of severe infection and large volume.Results The patients were followed up from 3 to 12 months(mean 7.82 months).The limbs of all the patients underwent bypass graft with vascular prosthesis were salvaged successfully,patients of which had secondary wound healing and had not intermittent lameness.One of two patients performed ligation of artery was salvaged successfully but had severe intermittent lameness,another patient underwent high amputation above knee because of ischemic gangrene.ConclusionFor infected femoral artery pseudoaneurysm,the operative treatment including excision of infected femoral artery pseudoaneurysm,exhaustive debridement and bypass graft with vascular prosthesis is effective and safe.

With the development of pharmacogenetics and pharmacogenomics,pharmacoepigenetics potentially offers another level of explanation for interindividual variations in drug response that cannot be accounted for on the basis of genetic polymorphisms.Many genes encoding enzymes,drug transporters,transcription factors,drug targets,and nuclear receptors are under epigenetic control,which has implications in the context of interindividual variations in drug response as well as drug resistance during cancer treatment.In this overview,we summarize the newest advancement in this field.

Background and purpose:Hypermethylated in cancer 1 (HIC1) is silenced in multiple cancer cells and tissues by DNA methylation of epigenetic modification, which may modulate the initiation and progression of tumors. However, there are few reports about this phenomenon in prostate cancer. This study aimed to investigate the status of HIC1 promoter methylation in prostate cancer using methylation methods.Methods:Methylation-specific polymerase chain reaction (MSP) and bisulfate sequencing PCR (BSP) were used to detect the methylation status ofHIC1 promoter in prostate cancer cell lines PC3 and C4-2B, prostate normal cell line PrEC, primary Chinese PCa tissues and the respective healthy control cases.HIC1 expression level was respectively determined by reverse transcription-PCR (RT-PCR) and Western blot assays in PC3, C4-2B and PrEC cells treated with 5-Aza-CdR.Results:We found that the percentages of HIC1 promoter methylation were 78.23%, 72.15% and 10.63% in PC3, C4-2B and PrEC cells by MSP analyses. Moreover, the levels of methylatedHIC1 promoter in 36 primary Chinese PCa tissues compared with the respective healthy control cases were 80.30%vs 31.56%. Expressions ofHIC1 mRNA and protein level were restored in PC3 and C4-2B cells after 5-Aza-CdR treatment.Conclusion:These findings demonstrate thatHIC1 promoter region is hypermethylated in prostate cancer, which results in silence or downregulation ofHIC1. The status ofHIC1 methylation can be a valuable marker in the early stage of prostate cancer and a potential therapeutic target.
