Objective To explore the reliability and validity of the simplified Chinese version of the Oswestry disability index (SCODI) and the curative effect of community-based rehabilitation for patients with lumbar disc herniation (LDH). Methods 165 patients with LDH received community-based rehabilitation according to the severity of their LDH. Before treatment and after 3 months, the SCODI, the Roland-Morris disability questionnaire (RMDQ) and a visual analogue scale (VAS) were used to evaluate the effects. The reliability and validity of the SCODI was thus tested. The reliability analysis included internal consistency as measured by Cronbach's coefficient,and test-retest reliability as measured by an interclass correlation coefficient (ICC). The validity analysis used Spearman's correlation coefficient (for concurrent efficacy validity) and factor analysis (for construct validity). The correlation between SCODI, RMDQ and VAS results was analyzed. Results There was statistically significant functional improvement and better QOL in LDH patients after community-based rehabilitation. The SCODI showed good validity and reliability. There was significant correlation among the SCODI, RMDQ and VAS results. Conclusion Community-based rehabilitation can significantly alleviate symptoms for patients with LDH and improve their QOL.The SCODI is a reliable and valid instrument for measuring the curative effect of community-based rehabilitation on patients with LDH.

Objective To analyze the control strategy of malsria in Sihong County for the recent 10 years and to evaluate its control effect.Methods The individual questionnaires of cases,the historical data of malaria control and the endemic situation of malaria in Sihong County from 1997 to.2007 were collected and analyzed.Results Two malaria Cases were reported in 2 towns of Sihong County in 1997,and the endemic situation rebounded in 1998 with 21 cases distributed in 12 towns.In 1999,the number of cases who distributed in 16 towns increased to 65.Endemic outbreaks occurred in some districts in 2000 and 2001 when the case number increased to 477 and 488,respectively,and the incidence increased to 4.77 and 7.78 per 10 000 people,respectively.After the comprehensive mesgures with an emphasis on infection source management and vector control were implemented,the incidence decreased to 0.99 per 10 000 people in 2007 and the endemic situation became stable.Conclusions Though the measures of malaria control in Sihong County are effective,surveillance should be strengthened to prevent the endemic situation from rebounding.

Objective To study the effect of relaxation therapy on sleeping quality of patients with post cran- iocerebral traumatic syndrome.

Objective To investigate the inhibitory effect and mechanism of rosiglitazone on chemokines secretion in renal tubular epithelial cells (HK-2) stimulated by lipopolysaccharide (LPS). Methods Cells were divided into four groups: control (CON), LPS (1 mg/L),rosiglitazone (10 μmol/L), rosiglitazone (10 μmol/L) +LPS (1 mg/L). MCP-1 and IL-8 expression was measured using real time PCR and ELISA. PPARγ was knockdown by RNAi to investigate whether the inhibitory effect of rosiglitazone was PPARγ-dependent or -independent. The NF-κB in nucleus was detected by Western blotting. The DNA binding activity of NF-κB was determined by electrophoretic mobility shift assay. Results Compared with CON group, the expressions of IL-8 and MCP-1 were increased by (4.30±0.45) and (4.80±1.29) times in mRNA level, (1.39±0.18)and (2.11 ±0.47) times in protein level, respectively, in LPS-stimulated HK-2 cells (P＜0.05).Application of rosiglitazone followed by LPS significantly reduced IL-8 and MCP-1 secretion compared with LPS group (decreasing by 66.37% and 71.88% in mRNA levels, while 41.68% and 47.87% in protein levels) (P＜0.05). In pcDNATM 6.2-GW/EmGFP-miPPARγ transfected cells, IL-8and MCP-1 only were decreased by 18.16% and 16.83% in mRNA level, while 11.39% and 11.86%% in protein level in rosiglitazone pretreated group, showing no significant difference compared with LPS group. Rosiglitazone did not block NF-κB nuclear translocation while significantly inhibiting the DNA binding activity of NF-κB. Conclusions Rosiglitazone inhibits the expressions of MCP-1 and IL-8 via a PPARγ-dependent mechanism in HK-2 cells, resulting from inhibition the DNA binding activity of NF-κB.

Fifteen patients with chronic renal failure(CRF)underwent laparoscopic cholecystectomy(LC)at carbon dioxide(CO2)pneumoperitoneum pressure of 10-12 mm Hg(Group A,n=9)or 13-15 mm Hg(Group B,n=6).Renal function and urinary volume(UV)of Group A showed no remarkable change following the operation.But in Group B,the levels of blood urine nitrogen(BUN)and serum creatine(Scr)were increased significantly,and creatinine clearance rate(Ccr)and UV were remarkably decreased(P＜0.05).These variants gradually retumed tO the preoperative levels after 1 week.The analysis showed that laparoscopic choleeystectomy at CO2 pneumoperitoneum pressure of 10-12 mm Hg in CRF patients might be safe.Higher CO2 pneumoperitoneum pressure could result in reversible renal Email:yuanhuizhong2000@yahoo.com.cnfunction change.

Objective To investigate the relationship between the variation of endothelial progenitor cells (EPC) number and cardiovascular diseases (CVD) in maintenance hemodialysis (MHD) patients ,and discuss the function of EPC in the progression of CVD in MHD. Methods One hundred and fifteen MHD patients over 18 years whose dialysis vintage was over six months from Department of Nephrology, Renji Hospital, Shanghai Jiao Tong University School of Medicine were enrolled. They were divided into CVD group and non ? CVD group by medical history, electrokardiographie (EKG), cardiac ultrasound, peripheral vascular imaging and cardiovascular imaging. Peripheral blood (5 ml) was collected for detecting EPC number by flow cytometry as CD34/CD133/vascular endothelial growth factor receptor 2 (VEGFR2) cells. The EPC number between CVD group and non?CVD group was compared. The relationship between the decrease of EPC number and CVD risks in MHD patients was analyzed by logistic regression analysis. In a three?year follow?up, the death and new CVD events of the two groups were compared in order to discuss the relationship between EPC number and adverse events. Results Among 115 MHD patients, the average age was 61.57 ± 12.76, male/female was 71/44, the average dialysis vintage was (86.24 ± 56.31) months, the average Kt/V was 1.69 ± 0.29 and average ultrafiltration volume was (2.48 ± 0.90) L. Forty?four patients in 115 (38.3%) were with concurrent CVD. The EPC number in CVD group was significantly lower than that in non CVD group (P=0.015). The CVD group had higher serum phosphate (P=0.013), higher glycosylated hemoglobin (P<0.001), but serum calcium, intact parathyroid hormone (iPTH) and other indicators had no significant difference between two groups. Multiple Logistic regression analysis showed that older age (OR=1.061), history of diabetes (OR=9.796), dialysis vintage (OR=1.015), serum phosphate (OR=3.766), decrease of EPC number (OR=0.909) were the independent impact factors of CVD events in MHD patients. There were 22 patients of the 115 MHD patients had encountered a new CVD event in a three?year follow?up between December 2012 and December 2015, 9 patients from the CVD group and 13 patients from the Non?CVD group, and there was no significant difference between two groups (P=0.776). Nine patients from the CVD group and 7 patients from the Non?CVD group died in the follow?up, and there was no significant difference (P=0.111). Seventy?one MHD patients from the non?CVD group were divided into two groups by the median of EPC number. There were 3 patients in the higher EPC number group encountered CVD events and 10 patients in the lower EPC number group encountered CVD events, which had significant difference (P=0.024). Conclusion The decrease of circulating EPC number may be related with CVD events in MHD patients. Even adjusted by age, sex, diabetes, dialysis vintage and serum phosphate, decreased EPC number is still the independent risk factor of CVD events in MHD patients. The decrease of EPC number in MHD patients may be used to predict the occurrence of cardiovascular events.
