Objective To observe the effect of monochromatic infrared energy(MIRE)on diabetic periphe- ral neuropathy(DPN).Methods Seventy-four subjects with diabetic peripheral neuropathy who were tested by Semmes-Weinstein monofilaments(SWM)were randomized into 2 groups:a conventional management group and a conventional management plus MIRE group.Then the patients'sensory function and other DPN symptoms were evalu- ated by the SWME and the score of Michigan Neuropathy Screening Instrument.Results After treatments,there was a decrease(P<0.01)in the number of the sites insensitive to SWME(grade 5.07),and MNSI scores were sig- nificantly decreased(P<0.01).The MIRE management was more effective than conventional management.Con- clusion Monochromatic infrared energy is perhaps a safe,non-pharmaceutical and non-invasive method for the treat- ment of diabetic peripheral neuropathy.

Journal of Applied Clinical Pediatrics 2006;0(13):-
The diagnosis of myocardial damage in systemic lupus erythematosus(SLE) is mainly based on clinical symptoms,physical examinations and electrocardiographic abnormality,echocardiographic changes,and myocardial enzymologic diversity in general.In recent years,it has been suggested that cardiac troponin I possesses high sensitivity and specificity in the diagnosis of myocardial damage.Lupus myocardial damage is diagnosed definitively depending on endomyocardial biopsy.Its treatment has been empirical,and hormone combined with immunodepressive is routine treatment.According to pathogenetic condition,there are still several therapies such as intravenous immunoglobulin therapy,blood purification and autologous hematopoietic stem cell transplantation,extracorporeal membrane oxygenation,and so on.Most often,myocardial dysfunction in SLE is of subclinical progression,and that early diagnosis and prompt treatment may play an important role in relieving patients' condition,raising quality of life and improving prognosis.

A 64-year old man was admitted on July 2011 with masses both in liver and right kidney.After PET-CT and blood test examination,dual primary advanced cancers were speculated to be co-existed in this patient,which having poor prognosis.By evaluation with comprehensive geriatric assessment,the patient also had hypertension,diabetes and atherosclerosis,liver and renal insufficiency.After multidisciplinary consultation and detailed discussion with the patient,the decision of no surgery and just keep the follow-up was made.The patient has been followed up for 18 months and the functional evaluation is the same as before.It is very important to evaluate the risk/benefit equation and improve the standard of care,and make the decision as patient centered rather than disease-centered in the elderly patients.

Objective:To explore the value of clinical pharmacist in clinical treatment through the pharmaceutical care on a patient with Japanese B encephalitis complicated with pulmonary infection. Methods:Clinical pharmacist participated in the whole treatment process and gave suggestions on the selection,dosage and course of the drugs prescribed for anti-virus, anti-epilepsy and anti-infection by focusing on the drug interactions and adverse reactions. Results:The treatment course of the patient was smooth, and the pathoge-netic condition was brought under control gradually while no obvious adverse drug reactions occurred. Conclusion:The work of clinical pharmacist can help to optimize treatment programs to ensure the safety and effectiveness of medication.

Objective To investigate the transactivating effect of hepatitis C virus(HCV)core protein on inducible nitric oxide synthase(iNOS)gene promoter and the molecular biological mecha- nisms of HCV pathogenesis.Methods Polymerase chain reaction(PCR)technique was employed to amplify the sequence of iNOS promoter by using HepG2 genomic DNA as template,and the product was cloned into pGEM-T vector.The iNOSp gene was cut from T-iNOSp by KpnⅠand XhoⅠ,and then was cloned into pCAT3-Basic,the constructed vector was named as pCAT3-iNOSp,pCAT3-iN- OSp was transfected into the LO_2 cell line.LO_2 cell was also cotransfected with pcDNA3.1(-)-core and pCAT3-iNOSp by FuGENE 6 transfection reagents.The LO_2 cells transfected with pCAT3-Basic was used as negative control.The activity of CAT in LO_2 cells was detected by an ELISA kit after 48 hours,which reflected the transactivating function of HCV core protein to iNOS gene promoter.Re- sults The expressive vector pcDNA3.1(-)-core and report vector pCAT3-iNOSp had been construc- ted and confirmed by restriction enzyme digestion and sequencing.The expression of CAT in LO_2 cells transfected with pCAT3-iNOSp and peDNA3,1(-)-core was 11 times as higher as that of pCAT3-bas- ic,and 6 times as higher as that of pCAT3-iNOSp.Conclusion It is suggested that HCV core protein can transactivate iNOS gene promoter.

In order to screen genes transregulated by core protein of hepatitis C virus, cDNA microarray technology was employed to detect the gene expression change between HepG2 cells transfected with pcDNA3 1(-) core and the empty vector, respectively. Among 1152 genes, there were 95 genes with different expressions, of which 45 genes were upregulated and 50 genes were downregulated in HepG2 cells transfected with core protein expression plasmid. These genes transregulated by HCV core protein included human genes encoding proteins involved in cell proliferation, differentiation, apoptosis, signal transduction and immune regulation. Therefore, the results provided some new clues for further clarifying the molecular biology mechanism of pathogenesis and tumorigenesis of HCV core protein

Hepatitis C virus (HCV) non structure 3 (NS3) protein and hepatitis B virus (HBV) X protein expressing plasmids were constructed with the vector pcDNA3 1(-). The plasmids were transfected into HepG2 cells and the viral proteins expressed in HepG2 cells were identified using Western blotting methods. Then the two recombined plasmids were transfected into HepG2 cells and were cotransfected into HepG2 cells with reporter plasmid pCAT3 promoter. The activity of CAT enzyme was detected by a CAT ELISA assay kit, which reflected the transactivating function of two proteins on SV40 early promoter. The findings indicated that the expression of two viral proteins were successfully detected in soluble protein cell extracts of transiently transfected HepG2 cells. HCV NS3 protein transactivated the CAT enzyme expressed at a value 3 5 fold higher than the control, while HBX protein transactivated at a value 4 4 times. It arrived at 8 5 times when transfected with two plamids simultaneously. The activating effect was increased in relation to the amount of plasmids. It was suggested that the two kinds of viral proteins had a transactivating effect on SV40 early promoter, and they acted synergistically. These results might contribute to explaining the mechanisms of liver injury or tumorigenesis induced by HCV or/and HBV infection
