Objective:To assess the relationship between Insulin-like growth factor-I(IGF-I) and TCM syndrome of acute cerebral infarction by measuring IGF-I levels in patients of acute cerebral infarction.Methods:100 patients of acute cerebral infarction with 48 hours after onset were divided into three groups by TCM syndrome.The IGF-I levels in plasma were measured by saturation analysis of radioimmunoassay.Results:The IGF-I levels in plasma was(10.39?1.56)ng/ml in the group of wind-phlegm syndrome and stasis,(12.96?2.27)ng/ml in the group of wind-phlegm syndrome and exuberance of re,(13.54?3.22)ng/ml in the group of stirring of wind due to de ciency of yin.These values showed statistically signi cant di erence between groups.Conclusion:Acute cerebral infarction occured most frequently in the group of wind-phlegm syndrome and stasis,the IGF-I levels showed signi cant decrease in this group.

To investigate the expression and clinical significance of p27kip1 protein in primary liver cancer, the expression of p27kip1 protein and the relationship with clinicopathological factors were studied in primary liver cancer by using SABC immunohistochemical staining in specimens of 40 cases of primary liver cancer and 20 cases of liver cirrihosis. Our results showed that positive expression rate of p27kip1 protein in primary liver cancer was 37.5% (15/40), which was lower than that in benign lesion of liver 80.0% (16/20, P<0.01). The expression level of p27kip1 protein in primary liver cancer showed significant differences in tumor size, Edmonson histological grade, portal invasion, lymph node metastasis, TNM stage (P<0.05, for all), but not significantly correlated with patient's age and histological types. Log rank test showed that the p27kip1 expression was significantly related with prognosis of the patients (P<0.05), and the prognosis of the patients with p27kip1 positive expression was markedly better than that of those with p27kip1 negative expression. It is concluded that the expression of p27kip1 was significantly related clinicopathological factors of primary liver cancer. p27kip1 protein may be used as a novel tumor marker for primary liver cancer.

Objective To study the effect of hypothemah on the early inflammatory reaction in acute lung injury induced by intestinal ischemia-repeffusion(IlR)in rabbits.Method Seventy-two healthy rabbits provided by Peking Union Medical Colege Hospital Anhnal center were randomly divided into four groups(n=18 pergroup):(1)normothermia control group (rectal temperature 37-38 C;sham group);(2)normothermia IlR group(rectal temperature 37-38 C);(3)mild hypothermia HR group(rectal temperature 32-35℃);and (4)moderate hypothermia IIR group(rectal temperature 28-31.9C).Acute lung injury was induced by claIllp.ithe superiornteric artery(SMA)for 1 hour and declamping the SMA for 6 hours.Hypothermia WaS induced by surface cooling.Before and 2.4 and 6 hours after IIR,the Olasmlevels o,IL-,IL-6 and IL10 were measured.All rabbits were killed 6 hours after IIR and water content in lung tissue Wttk'assessed.Iaght mieropic examination was performed tbr morphological assessment of the hmg.The data were analyzed by AN()VA.Statistical significance wag dned as a P of<0.05.Results In the IIR groups,the plasma levels ofTHE-a.IL-l,IL-6 and IL-10 and lung water were increased.There Was evidence of acute lung injury from morphologi-cal assessment of the lung.The acute lung injury induced by IIR was improved by hypethennia.Mild hypothermia Was similar to moderate hypothermia for the treatment of acute lung injury induced by IIR.ConclusiotMild hy-pothermia and moderate hypothermia Can significantly improve acute lung injury induced by IIR in rabbits.Mild hypothea had similar efficacy to moderate hypothermia for the treatment of acute lung injury induced by IIR.

Objective To discuss the pathogenesis of the statin-induced rhabdomyolysis in renal transplant recipients.Methods We presented two renal transplant recipients who developed rhabdomyolysis in 2012 in our hospital.The clinical presentation,laboratory results,diagnosis and treatment of the two patients were analyzed retrospectively.The basic immunosuppressive agent of two patients was cyclosporine A.The recipients developed rhabdomyolysis following simvastatin lipidlowering therapy,and one patient suffered acute renal failure simultaneously.Acute tubular injury was confirmed by renal biopsy.Finally,the symptoms of the two patients were relieved completely,creatine kinase (CK) returned to normal after the satins discontinued and saline,sodium bicarbonate and diuretics were given.The renal failure patient underwent plasma exchange and CRRT,and the renal function returned to normal.Results The level of cyclosporine A should be monitored when the renal transplant patient was given statins,especially whose basic immunosuppressive agent was cyclosporine A.At the same time we should pay more attention to the symptoms of the myotoxic side effects and avoid using the drug which was also metabolized by CYP3A4.Conclusion Physicians should be aware of the potential risks of combined therapy of statins which are metabolized by P450CYP3A4 and cyclosporine A in transplant patients.If using it is advisable to begin with small dosage and monitor the CK level.

Objective To compare the long-term effectiveness of anti-interleukin-2 receptor antibodies vs.rabbit antithymocyte globulin as induction therapy in kidney transplantation.Methods Between 2006 and 2010,371 recipients of kidney transplants were treated with calcineurin inhibitors (CNI),mycophenolate mofetil and prednisone.261 patients of them received induction therapy with anti-interleukin-2 receptor antibodies (IL2Ra group),and 88 patients received rabbit antithymocyte globulin (rATG group).All the patients received ganciclovir against cytomegalovirus and SMZ against pneumocystis carinii.The data of delayed graft function (DGF),the rate of acute rejectin (AR) and infection in the first year and patient/allograft long survival rate in two groups were retrospectively analyzed during a follow-up period of 1 to 5 years postoperatively.Results There was no significant difference in the sex,age and causes of end-stage renal disease between the two groups.The rATG group had more kidney transplants from deceased donors (P<0.01 ) and the cold ischemia time was longer than that of the IL2Ra group (P<0.01 ).The IL2Ra group and the rATG group had similar incidence of DGF (3.1% vs.1.8%,P>0.05).One year after operation,the incidence of AR in IL2Ra group and rATG group was 10.7% and 2.7% respectively (P<0.05),and the incidence of infection in IL2Ra group and rATG group was 14.9% and 21.8% respectively (P>0.05).One-,two- and three-year patient survival rate in IL2Ra group was 98.9%,98.9% and 98.5% respectively,and that in rATG group was all 98.2% (P>0.05).The one-,two- and three-year allograft survival rate in IL2Ra group was 98.5%,98.1% and 97.7% respectively,and that in rATG group was all 97.3% (P>0.05).Conclusion rATG is more effective than IL2Ra preventing from acute rejection and does not increase the risk of infection for induction in kidney transplant recipients.

Patients with chronic hepatitis B (CHB) often have immune-mediated liver injury, and it is considered that the interaction between viral infection and immune response is an important cause of disease progression. CHB can progress to liver fibrosis, liver cirrhosis, and even hepatocellular carcinoma (HCC). This article reviews the discovery of T helper 17 (Th17) cells and regulatory T (Treg) cells, describes their own features, and elaborates on their role and mechanism of action in maintaining the stability of the immune system. This article also analyzes the role of Th17/Treg cell imbalance in CHB, liver fibrosis, liver cirrhosis, and HCC and points out that Th17/Treg cell imbalance may promote the aggravation of HBV-related liver diseases.

The JAK/STAT/SOCS signaling pathway can mediate a variety of cytokines involved in inflammation, tumor, and autoimmune diseases and it also plays an important role in hepatitis B virus (HBV) infection-related liver diseases. This article briefly reviews the structure and signal pathway regulation of JAK-STAT and SOCS and elaborates on their role in the development and progression of HBV-related chronic hepatitis B, liver cirrhosis, liver failure, and hepatocellular carcinoma. The final analysis shows that the JAK/STAT/SOCS signaling pathway is dysregulated in HBV-related liver disease and is involved in the development and progression of the disease, and it may even influence the treatment and prognosis of the disease.
