To explain the relation between diabetic vasculopathy and'Blood blocking collaterals and phlegm turbidness not being removed'proposed by Mr.ZHU Kan-yu.It is believed that the turbidness is the basic pathological product during the development of diabetes.Blood glucose remains high,which reflects the disorders of transportation and distribution of turbid yin and qi in the body.That is to say that the thick coreal nutrients in the vessels are unable to be distributed and absorbed but stay in the vessels as turbid pathologic factors.Blood stasis and phlegm is the further result of turbid pathologic factors.The TCM explanation of diabetic vasculopathy is that phlegm,turbidness,blood stasis block the meridians and collaterals.Those visible pathological factors deposit in vessels and cause narrow vessels and thick walls.Meanwhile the deposit stimulates,spreads,erodes and burns the walls and finally ruins the walls.

The herpes simplex virus type 1 (HSV-1) VP22, is one of the most abundant HSV-1 tegument proteins with an average stoichiometry of 2 400 copies per virion and conserved among alphaherpesvirinae. Many functions are attributed to VP22, including nuclear localization, chromatin binding, microtubule binding, induction of microtubule reorganization, intercellular transport, interaction with cellular proteins, such as template activating factor I (TAF-I) and nonmuscle myosin II A (NMIIA), and viral proteins including tegument protein VP16, pUS9 and pUL46, glycoprotein E (gE) and gD. Recently, many novel functions performed by the HSV-1 VP22 protein have been shown, including promotion of protein synthesis at late times in infection, accumulation of a subset of viral mRNAs at early times in infection and possible transcriptional regulation function.

Molecules can enter the nucleus by passive diffusion or active transport mechanisms, depending on their size. Small molecules up to size of 50-60 kDa or less than 10 nm in diameter can diffuse passively through the nuclear pore complex (NPC), while most proteins are transported by energy driven transport mechanisms. Active transport of viral proteins is mediated by nuclear localization signals (NLS), which were first identified in Simian Virus 40 large T antigen and had subsequently been identified in a large number of viral proteins. Usually they contain short stretches of lysine or arginine residues. These signals are recognized by the importin super-family (importin α and β) proteins that mediate the transport across the nuclear envelope through Ran-GTP. In contrast, only one class of the leucine-rich nuclear export signal (NES) on viral proteins is known at present. Chromosome region maintenance 1 (CRM1) protein mediates nuclear export of hundreds of viral proteins through the recognition of the leucine-rich NES.

UNLABELLEDObjective: In order to assess the integrative cardiopulmonary function after percutaneous coronary intervention (PCI) in patients with stable coronary artery disease (CAD), we used symptom limited maximum cardiopulmonary exercise testing (CPET).

METHODSAll 59 patients diagnosed stable CAD by coronary angiography and echocardiography from August to December of 2014 in our hospital, were divided two groups. PCI group, 31 patients received PCI and drugs. Control group, 28 patients received drugs therapy only. All patients performed CPET before and after the treatment.

RESULTSAll patients safely completed CPET without any complications. The control group, all functional parameters were unchanged (P > 0.05). PCI group, the anaerobic threshold, peak oxygen uptake and peak oxygen pulse increased significantly (P < 0.05) from baseline,but not for others (P > 0.05). For individual analysis, PCI group had higher rates of increase (≥ 10% of baseline) in both peak oxygen uptake and peak oxygen pulse than those of control group (P < 0.05).

CONCLUSIONCPET is an objective, quantitative, safe and effective method to evaluate the clinical therapeutic efficiency. PCI can improve the integrative cardiopulmonary function in CAD patients.

Objective: To summarize the application and efficacy of fresh autologous pericardial tri-leaflet pulmonary artery conduit for right ventricular outflow tract reconstruction in patients with complex congenital heart disease (CHD). Methods: A total of 18 relevant patients received fresh autologous pericardial tri-leaflet pulmonary artery conduit for right ventricular outflow tract reconstruction in our hospital from 2007-08 to 2012-12 were studied. The patients were at the mean age of (2.12±2.02) years with body weight ≥ (9.41±3.62) kg including 10 male. Echocardiography was followed-up at 1 month, 3-6 and ≥12 months post-operation. Results: All 18 patients had successful operation. 2 patients died at early post-operative stage including 1 with severe infection and respiratory failure, 1 with low cardiac output syndrome. 16 survivors had the average ICU stay time (140.2±124.5) h, mechanical ventilation (94.4±87.6) h, transcutaneous O2 saturation at quiet condition without O2 inhalation at (97.1±3.34) %. There were 3 patients lost contact during followed-up period and 13 received periodical examination. No obvious calcification was found in chest X-ray; echocardiography showed infrequent stenosis of right ventricular outflow tract, pulmonary valve ring and main pulmonary artery; left and right pulmonary artery stenosis at the second place. Conclusion: The safety and efficacy of fresh autologous pericardial tri-leaflet pulmonary artery conduit for right ventricular outflow tract reconstruction was fine for treating relevant patients, the mid and long term effect should be further observed.

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.

ObjectiveTo investigate the risk factors for contrast-induced nephropathy (CIN) after endovascular therapy in patients with peripheral arterial diseases and to evaluate the conformance of serum cystatin C (Cys C) and serum creatinine in diagnosis of CIN. Methods In this prospective,single center study,in-hospital patients with peripheral arterial diseases undergoing non-emergency endovascular therapy from July 2010 to April 2011 in our hospital were enrolled.CIN was defined asScr increase ≥25％ after angiography.General clinical characteristics and blood biochemical parameters were compared between the non-CIN and CIN groups.Logistic regression analysis was performed to determine risk factors.Changes compared to baseline level in serum creatinine and Cys C at predefined time-points were evaluated.Results A total of 367 patients were enrolled in the study.The proportions of patients with diabetes mellims and treatment with diuretics before angiography,contrast-media dosage were significantly higher in the CIN group than those in non-CIN group (P＜0.05,＜0.01,＜0.01).Logistic regression analysis indicated that diabetes mellitus,contrast-media dosage were risk factors for CIN.Several serum Cys C increase criteria at 24 hours after contrast media exposure all had low sensitivity for predicting a Scr increase ≥25％.Only small overlapped regions were found in Venn diagram between several increasing criteria according to serum Cys C and serum creatinine criterion. Conclusions Diabetes mellitus,contrast-media dosage are independent risk factors for CIN.The results of several increasing criteria according to serum Cys C in evaluating contrast-induced AKI are not coincident well with that of serum creatinine criterion.

Objective To investigate the effect of exercise prescription on foot perfusion and ulcer healing in patients with diabetic foot ulcer (DFU) accompanied with peripheral arterial disease (PAD).Methods Sixty patients with DFU and PAD were divided into exercise group and control group.The patients in the exercise group took exercise therapy training,ensuring that they could follow the exercise prescription.The patients in the control group had no exercise requirements.After the treatment for 12 weeks,ankle brachial index (ABI),transcutaneous oxygen tension (TcPO2),skin temperature,body mass index (BMI),HbA1C,and the ulcer healing rate in the two groups were compared,the satisfaction and compliance in the exercise group were evaluated,and the adverse events of the treatment were recorded.Results After the treatment for 12 weeks,the ABI,TcPO2,and foot skin temperature in the two groups increased and HbA1C decreased(P＜0.05 or P＜0.01).TcPO2 increased 5.25 mm Hg(1 mm Hg=0.133kPa),skin temperature increased 0.45℃,and BMI decreased 0.69 kg/m2 in the exercise group,while TcPO2 increased 2.59 mm Hg,skin temperature increased 0.28℃,and BMI increased 0.02 kg/m2 in the control group,showing significant differences in the three index changes between two groups (P＜0.01).The healing rate in the exercise group was higher than that in the control group (53.6％ vs 25.9％,P ＜0.05).The patients'compliance and satisfaction to the exercise therapy were 90％ and 94％,respectively.The incidence of adverse events in the exercise group had no causal relationship with the exercise prescription.Conclusion The exercise prescription in the study can improve the foot perfusion,and promote ulcer healing.It has the advantage of high safety,patients'compliance and satisfaction.
