Objective:To observe the expression of immunoregulatory cytokines including interleukin-4(IL-4,Th2)、 interferon-?(IFN-?,Th1)、interleukin-betal (IL-1?) in the tissues of hepatocellular carcinoma(HCC),and to investigate the relationship between the changes of immunoregulatory cytokines in patients with hepatocellular carcinoma and intrahepatic metastasis and recurrence.Methods:The immunoregulatory cytokines:IFN-?(Th1)、IL-4(Th2)、IL-1? were analyzed by RT-PCR.Results:34 cases with HCC were compared with the ones with liver cirrhosis,the expression rates and density of IFN-?(Th1) in the tissues of hepatocellular carcinoma were much lower than that in the liver cirrhosis,they are 0.92?0.36(18/34,53.9%) and 1.63?0.64(12/15,80.0%),respectively.There is significant difference between them (P

Osteoclast (OC) are bone resorbing cells whose development and activity are under the influence of osteoblast (OB). The potential association between those two cell lineages is an area of significant interest. It was not until 1998 that osteoclast differentiation factor (ODF) and osteoprotegerin (OPG) was cloned. The two novel TNF superfamily members have been recently demonstrate to be the key extracellular regulators of osteoclasteogenesis and bone resorption both in vivo and in vitro, and they play important roles in osteoporosis development, diagnosis and treatment.

0.05).Two cases were lost to follow up,19 out of 21 cases were followed up.The follow-up duration was from 4 to 51 months[mean follow-up duration was(22.84?12.13) months].At last follow-up,10 cases(53%) had complete remission,4 cases(21%) had significant remission,4 cases(21%) had partial remission and 1 case(5%) had no remission.Tubulointerstitial lesions were related with prognosis(P1).Conclusions 1.The predominant clinical manifestation of primary FSGS is nephrotic syndrome in children.The not otherwise specified variant is the commonest pathological variant in primary FSGS.There is no relationship between patholo-gical types and clinical manifestations of FSGS.2.Most of the children with primary FSGS have a good short-term prognosis,but their long-term prognosis must be followed up.3.Tubulointerstitial lesions are risk factors for prognosis.

Objective To observe the microdose albumin in urine,carotid intima -media thickness(CIMT) of coronary heart disease(CHD)patients′and coronary Gensini score level,to investigate the correlation between the extent of coronary stenosis and microalbuminuria,CIMT.Methods 50 cases of hospitalized patients with CHD and healthy control group of 50 cases were selected,to compare the score between the two groups of microalbuminuria, CIMT and coronary Gensini.Results CHD group:microalbuminuria and CIMT were (38.36 ±19.51 )mg/L, (1.18 ±0.25)mm respectively.Healthy control group:microalbuminuria and CIMT were (27.52 ±15.44)mg/L, (0.76 ±0.17)mm respectively.Differences between the two groups were statistically significant(t =3.080,P =0.002;t =9.823,P =0.000).CHD group:coronary Gensini score was positively correlated with microalbuminuria, CIMT(r =0.288,P =0.430 r =0.308,P =0.290).Conclusion The correlation between CHD patients'microalbu-minuria,CIMT and the degree of coronary artery stenosis is positive.By measuring the microalbuminuria and CIMT,we can predict the extent of coronary artery stenosis.

Indolent B-cell lymphomas constitute a slow growing cancer of the lymphatic system. These lymphomas mainly include fol-licular lymphoma, chronic lymphocytic leukemia/small lymphocytic lymphoma, Waldenstom macroglobulinemia, marginal zone lym-phoma, and low malignant mantle cell lymphoma. These lymphomas are sensitive to chemotherapy and/or immunochemotherapy, but they cannot be cured. Furthermore, patient age at diagnosis, patient age at time of first onset or subsequent relapses, and compli-cations often influence the chemotherapy curative effect. At present, recent progress has been achieved in our understanding of dys-regulated pathways and immunologic anti-tumor responses in indolent lymphoma. In particular, the breakthrough of non-cytotoxic drugs renderschemo-freetreatment a near-future reality. In this review, we highlight these promising approaches, such as the com-bination of anti-CD20 antibodies with immunomodulatory drugs, mAbs directed against other surface antigens, and programmed cell death 1 (PD-1) receptor inhibitor or B-cell receptor signaling pathway inhibitors. Future phase III studies will evaluate the efficacy of these drugs in the context of non-chemotherapy and further clarify treatment status.

Objective: To explore relationship between heart rate variability (HRV) and lower extremity arterial disease (LEAD) in aged patients with type 2 diabetes mellitus (T2DM) and their clinical significance. Methods: A total of 65 T2DM inpatients with age 60~65 years were enrolled. According to LEAD condition, they were divided into T2DM + LEAD group (LEAD group, n=36), T2DM without LEAD group (NLEAD group, n=29) ，besides, normal control group was set up (n=23). The 24h dynamic electrocardiography was performed. Indexes of HRV were measured; meanwhile, blood pressure, indexes of glucose and lipid metabolism, CRP and plasma adiponectin were measured in all groups. Correlation analysis and multi-factor Logistic regression analysis were performed. Results: (1) Levels of SBP, HbA1c, LDL-C, CRP in LEAD group and NLEAD group were significantly higher than those of normal control group (P<0.05). Compared with NLEAD group, there were significant increase in course of disease [(3.00±2.00) years vs. (7.50±4.00) years], SBP [(140.24±8.95)mmHg vs. (147.61±7.58)mmHg], HbA1c [(6.40±0.70)% vs. (7.15±2.05)%], plasma fibrinogen（Fg）[(2.57±0.51) g/L vs. (3.02±0.71) g/L], LDL-C[(2.27±0.50) mmol/L vs. (2.81±0.71) mmol/L] and CRP[(2.01±1.79) mg/L vs. (3.14±2.92) mg/L] in LEAD group, P<0.05 all; (2) SDNN, SDANN, VLF and plasma concentration of adiponectin in LEAD group and NLEAD group were significantly lower than that of normal control group (P<0.05 all); Compared with NLEAD group, there were significant decrease in other indexes except rMSSD in LEAD group, P<0.05 all; (3) Spearman rank correlation analysis indicated that LEAD was positively correlated with course of disease, SBP, 2hPG, HbA1c, LDL-C, Fg, CRP (r=0.311~0.760, P<0.05 all), and negatively correlated with adiponectin and HRV indexes (r=-0.597~-0.317, P<0.01 all); (4) Multi-factor Logistic regression analysis indicated that course of DM, SBP, HbA1c, LDL-C, CRP were independent risk factors for LEAD in aged T2DM patients (OR=2.932~14.404, P<0.05). Conclusions: 1. The course of DM, SBP, HbA1c, LDL-C, CRP, adiponectin and HRV are related with LEAD in aged T2DM patients ; 2. Decreased HRV is an independent risk factor of LEAD in aged T2DM patients.

Objective To investigate the clinical therapeutic effect of different frequency electroacupuncture on poststroke hemidysesthesia.Methods Sixty patients with poststroke hemidysesthesia were randomly allocated to treatment and control groups, 30 cases each. Both groups received electroacupuncture at the same points. The electroacupuncture frequency was 100 Hz in the treatment group and 1 Hz in the control group. The clinical therapeutic effects were evaluated in the two groups at 30 days after treatment.Results The total efficacy rate and the cure and marked efficacy rate were 93.3 and 80.0, respectively, in the treatment group and 86.0% and 43.3%, respectively, in the control group. There was no significant difference in the total efficacy rate between the two groups (P<0.05).There was a statistically significant difference in the cure and marked efficacy rate between the two groups (P<0.05). There was a statistically significant pre-/post-treatment difference in the limb dysesthesia score in the two groups (P<0.05). There was a statistically significant post-treatment difference in the limb dysesthesia score between the treatment and control groups (P<0.05).Conclusions Electroacupuncture is an effective way to treat poststroke hemidyse- sthesia. High frequency electroacupuncture is more effective than low frequency electroacupuncture.
