0.05). Regarding to the grade of irradiation mucositis, the majority of patients in the treatment group were at stage Ⅰ-Ⅱ,while those in the control at stage Ⅲ-Ⅳ(P0.05).No adverse drug reaction was observed in both groups during irradiation process.Conclusion:Actovegin can postpone the development of irradiation oropharyngeal mucositis and decrease the incidence of gradeⅢ and Ⅳmucositis.

OBJECTIVE To investigate the influence of intermittent catheterization methods and indwelling catheterization methods on the urinary tract infection in patients with spinal cord injury.METHODS After eighty cases of spinal cord injury,the urine retention patients caused by bladder dysfunction were respectively used intermittent catheterization and indwelling catheterization.The urinary tract infection rates of regucally urine culture were compared.By use of intermittent catheterization,the bladder function was trained.Bacteria culture and identification of the urine from the patients were conducted after 15 or 30 days of intermittent catheterization and indwelling catheterization respectively.RESULTS The rates of urinary tract infection(colony count≥1?10 CFU/ml) after 15 or 30 days of intermittent catheterization were 32.6% and 31.5%,respectively.Which were significantly lower than those of indwelling catheterization(100%)(P

Objective To explore the effects of virtual reality (VR) combined with motor imagery therapy on the upper limb function of hemiplegic stroke survivors.Methods Thirty-nine hemiplegic stroke patients were divided randomly into a treatment group (n =20) and a control group (n =19).Both groups were treated with motor imagery therapy,but the treatment group also received VR training lasting 20 min/day,6 days/week for 8 weeks.All of the patients were assessed with the Fugl-Meyer (FMA) upper limb assessment,the modified Barthel index (MBI) and electromyography at the beginning and after eight weeks of treatment.Results Before the intervention there was no significant difference between the groups in any of the assessments.After eight weeks of treatment,all the assessment results in the treatment group were significantly better than those in the control group.Conclusion Virtual reality combined with motor imagery therapy can distinctly improve the upper limb motor function of hemiplegic stroke survivors and their ability in the activities of daily living.

Objective To analyze the clinical features of renal involvement associated with Behcet's disease (BD) through 1 case and to make a review of the literature in order to early diagnose and cure in time,thus decrease misdiagnosis and mistreatment.Methods This is a retrospective study.The case was diagnosed with BD and the renal damage was confirmed by renal biopsy.The clinical features and histology features were analyzed.Results The presentation of renal disease was edema,proteinuria and microscopic hematuria.The clinical spectrum of renal BD showed a wide variation.Amyloidosis (AA type),GN (nephritis),and microscopic vascular disease were the main causes of renal BD.Patients with vascular involvement had a high risk of amyloidosis and amyloidosis was the most common cause of renal failure in BD.Conclusion Kidney is one of the organs that can alter the prognosis of the BD,so the screening for renal damage must be done for each patient with this disease.Routine urine analysis and measurement of serum creatinine level are needed for early diagnosis of renal BD.Immunosuppressive drugs can be useful in selected cases.

Objective To clarify the protective effect of nrsodeoxycholic acid ( UDCA ) on endoplasmic reticulum stress-mediated apoptosis in pancreatic β-cell of streptozotocin ( STZ )-induced diabetic rats.Methods Rats( n =40) received a single injection STZ( 50 mg/kg) intra-peritoneally and formed a β-cell injury model.Weight-matched normal rats( the control group,n =10 ) were injected with the buffer alone.STZ-treated rats with persistent random blood glucose higher than 16.7 mmol/L for 1 week were considered as diabetic status( n=14 ),then divided randomly into STZ-induced diabetes mellitus ( DM ) group ( n =7 ) and UDCA-treated DM group ( n =7 ).UDCA (40 mg· kg- 1,d-1 ) was administered daily by intragastric intubations throughout the experimental period (30 d).During the entire experiment,blood glucose in all rats was assessed.By the end of the experiment,all rats were sacrificed with the pancreas removed and the blood sample collected immediately.Fasting insulin levels were assayed by radioimmunoassay.The morphological changes of pancreatic β-cells apoptosis were determined by TUNEL assay.RNA in pancreas was abstracted and microarray containing 89 pieces of apoptosis related genes was applied.The related gene expressions were detected by RT-PCR and Western blot.Results The concentration of blood glucose in diabetic rats was gradually decreased after UDCA treatment,but at the end of the experiment it was still higher than that in the normal control group.The treatment with UDCA raised the fasting insulin level in diabetic rats,but this concentration was significantly lower as compared to the control group.Based on TUNEL stained tissue sections,the percentage of β-cell apoptosis of UDCA-treated DM group was significantly lower than that of STZ-induced diabetic group(P＜0.05 ).Among 89 genes,42 genes up-regulated and 46 genes down-regulated in diabetic rats,some of which were ameliorated by UDCA treatment.The expressions of Caspase-3,Bax,Bip,and CHOP mRNA in pancreas of DM group were significantly up-regulated as compared with those in the control group ( P ＜ 0.05 ) ; while the expression of Bcl-2 mRNA was markedly down-regulated (P＜0.05 ).However,these parameters in the U DCA-treated animals showed a marked improvement.Conclusion Ursodeoxycholic acid seems to protect pancreatic β-cell from apoptosis in STZ-induced diabetes by attenuating the severity of endoplasmic reticulum stress.

?AIM: To study the association of the single nucleotide polymorphism ( SNP) rs1157699 in the calcitonin receptor-like receptor ( CRLR ) gene with primary angle closure ( PAC) in a Han Chinese population.?METHODS: All samples, involved 232 PAC cases and 306 controls, were obtained from an epidemiologic survey conducted in Funing, Jiangsu Province, China. Genotyping were carried out by TaqMan-MGB probe using the real time quantitative polymerase chain reaction system to study the relationship between SNP of rs1157699 in CRLR gene and PAC.?RESULTS: The prevalence of CRLRrs1157699 genotype was 67.4%, 30.0%, 2.6% for CC, CT, TT in cases, and 71.3%, 27.0%, 1.7% in controls respectively.There was no difference between the two groups in the distribution of genotype and allele frequencies of rs1157699 (P>0.05).?CONCLUSION:Our results do not support a significant role for rs1157699 in CRLR with PAC.

Objective To investigate the importance of plasmid-mediated quinolone resistance in the development of quinolone resistance in clinical isolates of gram-negative bacteria.Methods A total of 541 consecutive clinical isolates of gram-negative ba- cilli resistant or intermediate to ciprofloxacin were screened for the qnrA gene by PCR.Conjugation experiments were carried out with azide-resistant E.coli J53 as a recipient.The aac(6')-Ib-cr gene was detected.The mutations in the quinolone-resist- ance-determining region (QRDR) of the gyrA and parC genes were identified in qnrA positive strains.Results qnrA was identi- fied in 7 of the 541 strains.Among the qnrA positive strains,5 were Enterobacter cloacae.No qnrA was detected in nonfer- menters.Quinolone resistance was transferred in 4 of 7 qnrA positive strains.Transconjugants had 12-to 125-fold increases in MIC of ciprofloxacin relative to that of the recipient.Seven strains contained qnrA with a nucleotide sequence identical to that originally reported.Two transconjugants with higher ciprofloxacin MICs contained aac(6')-Ib-cr gene.Mutations occurred in the QRDR of the gyrA and parC genes in 5 PCR-positive clinical strains.Conclusions Transferable plasmid-mediated quinolone resistance associated with qnrA is highly prevalent in clinical strains of Enterobacter spp.aac(6')-Ib-cr gene and mutations in the quinolone targets may co-exist with qnrA,which may contribute to the further increase of resistance to quinolones.
