objective To analyze the risk factors of sepsis,and to elucidate the efficacy of high-flux hemofihration(HVHF)in the treatment of sepsis and the initiate opportunity of HVHF treatment on sepsis complicated with acute kidney injury(AKI). Methods Clinical data of 152patients with sepsis undergoing HVHF treatment were retrospectively analyzed.APACHE Ⅱ,APACHE Ⅲ and SAPS Ⅱ score evaluation before treatment and 24 h,48 h.72 h after treatment were performed.According to 28-day survival,patients were divided into survival group and death group.Clinical indicators before and 24 h,48 h,72 h after treatment were compared between groups.Risk factors influencing prognosis of patients were examined by multivariate regression analysis.Influence of AKI stages on prognosis of patients was studied. Resalts Lung and alimentary tract were the most frequent infection sites of sepsis.Twenty-eight days after HVHF treatment,74 patients (48.68%)survived,seventy-eight patients (51.32%)died among 152patients,and 4 patients(2.63%)needed sequent renal replacement therapy.Twenty-eight-day mortality was significantly lower than the mortality 88.78%±17.72%predicted by APACHE Ⅲ.APACHE Ⅱ,APACHE Ⅲ and SAPS Ⅱ Sscores decreased remarkably (P＜0.01) 24 hours after treatment.Age,number of dysfunctional organ,APACHE Ⅱ,APACHE Ⅲ,SAPS Ⅱ scores,undedying diseases,shock,AKI,severe acute pancreatitis,alimentary tract hemorrhage,cataphora and pressor agent were correlated with 28-d survival rate.Underlving diseases and APACHE Ⅲ were independent risk factors.Renal function recovery rate in AKI stage 1 was higher than that in AKI stage 2,3(P＜0.05).Twenty-eight-day mortality of patients without AKI was lower compared to AKI stage 1,2,3(P＜0.05),but 28-day mortality was not significantly different among AKI stage 1,2,3. Conclusions Prognosis of patients with sepsis is poor.HVHF can improve biochemical indicators and prognosis of patients effectively,and increase survival rate.Underlying diseases and APACHE Ⅲ are independent risk factors of 28-day mortality of sepsis patients.Twenty-eight-day mortality of non-AKI patients is obviously lower compared to AKI stage 1,2,3patients.AKI stage is correlated with 28-day renal function recovery rate,but not obviously correlated with 28-day mortality.

To cure one patient with spinal cord injury (SCI), who hospitalized for both legs couldn't moving for 21 years after external injury, by using the olfactory ensheathing cells (OECs) transplant and acupuncture treatment. The patient was diagnosed as ischemic SCI (below the T11) according to the neurological test and MRI for dorsal vertebra. T11 spinous process was made to be the center mark through operation with the length of about 3 cm. The area between the atrophique spinal cord and normal spinal cord without vessel was selected and injected with OECs 0.5?109 L-1. Hemostasis, stitching, binging and fixation were performed respectively, and normal treatment was given by using antibiotics. At 14 days after operation, the temperature on skin increased a little, and acupuncture treatment and rehabilitation therapy were performed. The acupoints were as following: Baihui (DU21), Yintang (EX-HN3), Hegu (LI4), Zhongji (RN3), Guanyuan (RN4), Biguan (ST31), Fengshi (GB31), Futu (ST32), Dubi (EX-LE5), Zusanli (ST36), Xuehai (SP10), Yinlingquan (SP9), Sanyinjiao (SP6), Jiexi (ST41), Taixi (KI3), Fuliu (KI7), Taichong (LR3), and Shenmai (BL62). The treatment was given by mild reinforcing and attenuating with 30-minute retention. The rehabilitation: The needle pressing, manipulation for muscular atrophy, bicycle practicing, andimperative standing were performed. After 2 weeks, the skin temperature of the patient increased with obvious improvement in his right leg. The physical strength of the patient was reinforced with less perspiration, and the patient could walk 3 km without fatigue, which indicated that after OECs transplant, treatment with acupuncture, massage and other rehabilitation trainings could facilitated the improvement of SCI of the advance stage as well as the amelioration of muscular atrophy.

Objective:To investigate the relationship of-308bp polymorphism in tumor necrosis factor-α (TNFa)gene and+252bp in lymphotoxin-α(LTα)gene with the clinical course and outcome of non-Hodgkin's lymphoma(NHL).Methods:The single base change in TNFα gene and LTα gene was analyzed among 96 Chinese patients with NHL and 72 normal controls by using PCR-restrictive fragment length polymorphism (RFLP).The clinical data were collected and survival analysis was performed.Results:In NHL patients,no statistcally significant association was found between the presence of a given TNF/LT haplotype status and clinical variables such as age,seX,disease stage,and so on.The patients carrying low-risk haplotype achieved a more sensitive response to first-line therapy than that in patients with high-risk haplotype(70.4%v 45.2%:P=0.018).The estimated 1-year progression-free survival rates in the high-risk and low-risk groups were 66.67% and 87.5%,respectively(log-rank test,P=0.0231).Kaplan-Meier method showed that the estimated 2-year and 4-year overall survival rates were 39.95%and 8.32%in patents carrying high-risk haplotypes and 65.13%and 46.52%in patients carrying low-risk haplotypes,respectively(log-rank test,P=0.0012).In multivariate Cox regression models.the TNF/LT haplotype status was found to be a dsk factor for outcome of NHL (P=0.034).Conclusion:There is an association between TNF/LT haplotype status and response to therapy and outcomes of NHL in Canton area,China.Detecting TNF/LT haplotype may be a sensitive method to evaluate the outcome of NHL.

AIM: To find the role of heat shock protein 90(HSP90) and tubulin in oxidative stress preconditioning in HepG2 cells.METHODS: The different doses of H2O2 were used to induce cell injury in HepG2 cells.MTT assay,Western blotting and confocal laser microscopy were also used.RESULTS: MTT colorimetry showed that preconditioning(50 mmo1/L H2O2) provided a temporary resistance against subsequent oxidative stress(500 mmol/L H2O2).Western blotting demonstrated that preconditioning increased the levels of HSP90 and tubulin in HepG2 cells,and lessen the declining of HSP90 and tubulin after stress.Tubulin and HSP90's colocalizations in cells with different doses of H2O2 were also observed under laser scanning confocal microscope.CONCLUSION: Tubulin might play important role in oxidative stress preconditioning in HepG2 cells by combining with HSP90.

Objective To evaluate the safety and clinical effect of homemad Costant coronary stent implantation.Methods The immediate and two-year follow-up results of Costant coronary stent implantation in severe coronary heart disease(CHD)patients were retrospectively analyzedin the General Hospital of Shenyang Command of PLA and the Guanzhou People's Hospital from Mar.2001 to Aug.2003.Results Implantation of 86 homemad Costant coronary stents was successfully performed in 71 severe CHD patients although 3 main adverse cardiac events(MACE)occurred during hospitalization(2 patients died and 1 patient had sub-acute in-stent thrombosis).Follow-up was made in 63 patients for(21.5?4.4)months on an average and 4 patients died.Repeat coronary angiogram in 21 patients showed that in-stent restenosis for Costant stent existed in 4 patients and in-stent restenosis in other types of stent was found in 3 patients and in-stent restenosis in all stents was found in 1 patient who died of shock and neo-coronary lesions was found in 5 patients.Costant stent restenosis rate was 7.9%(5/63);MACE rate was only 12.7%(8/63)during follow-up.Conclusion Homemad Costant coronary stent can be safely implanted in severe CHD patients with ideal long-term outcomes.

Objective To explore the role of transforming growth factor (TFG) -β and matrix metalloproteinases( MMPs) in the development of frozen shoulder. Methods Twenty-four patients who underwent shoulder arthroscopy were included, and were divided into frozen shoulder group (n = 12) and control group ( n = 12; n = 2 for shoulder instability, n = 5 for rotator cuff tear and n = 5 for subacromial impingement) . Joint capsule tissues at the rotator cuff interval were obtained, and the expression of TGF-β, MMP-1, MMP-2, MMP-3, MMP-9 and MMP-12 mRNA and protein was detected by Real-time PCR and Western blotting, respectively. Results The expression of TGF-p mRNA in frozen shoulder group and control group was 3.36 × 10~4 ±2.18 × 10~3 and 1.85 × 10~4 ±3.31×10~3, respectively, the expression of TGF-p protein was 1.55 ± 0.33 and 1.13 ±0.21, respectively, and there were significant differences between these two groups (P < 0.05). The expression of MMP1, MMP2, MMP3, MMP9 and MMP12 mRNA and protein in frozen shoulder group was significantly higher than that in control group(P <0.05) . Conclusion The higher expression of TGF-β and MMPs in joint capsule of frozen shoulder may be associated with the development of frozen shoulder.
