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 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.

Objective To observe the survival of myoblasts carrying hIGF-1 gene transplanted into the mice, and the expression of hIGF-1 in the transplanted mice. Methods Eighty four male C3H mice(20~30g,7~11w)were divided into four groups: group A, B, C and D (20 mice each group), and the remaining four mice were used as normal control. At the middle of the right gastrocnemius muscle, the mice in group A and B were injected with 1?10~6 myoblasts either carried with or without hIGF-1 gene. Muscle contusion at the middle of the right gastrocnemius muscle of the mice in group C and D was produced. At day 3 following injury, they were injected with 1?10~6 myoblasts either carried with hIGF-1 gene (group C) or without hIGF-1 gene (group D). At the day 2, 5, 10, 20, 30 after injection, four mice of each group were sacrificed randomly. BrdU staining in all mice were performed to evaluate cells surviving, and the expression level of hIGF-1 in group A and C was assessed by immunohistochemical staining and real-time-PCR. Results The BrdU staining in both normal and injured mice transplanted with myoblast carried with or without hIGF-1 were positive. hIGF-1 was expressed and secreted in both group A and C. Conclusion The myoblast carrying hIGF-1 gene transplanted into normal or injured mice can survive for a certain period of time, and can secrete hIGF-1.
