Chemokines are a class of functional chemotactic peptide. CXC chemokine class is a large family of chemokines in a sub- tribe. In the occurrence and development of tumor cells, there often accompanied by a series of molecular and biology change. CXC chemokine subfamily is closely related to the body' s immune response to tumor and biological behaviors of tumor. In this paper, CXC chemokine sub-Several members of the tribe and their receptor and tumor biological relationship are reviewed.

OBJECTIVE:To compare the cost of Xiangdan injection and Danshen chuanxiongqin injection in the treatment of unstable angina pectoris of coronary heart disease,and to provide reference for rational and economic drug selection. METHODS:42 inpatients with unstable angina pectoris of coronary heart disease were divided into Xiangdan injection group(group A,20 cas-es) and Danshen chuanxiongqin injection group (group B,22 cases). Two groups were given conventional symptomatic treatment according to the specific clinical situation;on this basis,group A was given Xiangdan injection 20 ml intravenously,qd;group B was given Danshen chuanxiongqin injection 10 ml intravenously,qd,for 14 d. Clinical efficacy and the occurrence of ADR were compared between 2 groups,and cost-minimization analysis was conducted. RESULTS:After treatment,total effective rate of group A and B was 95.00% and 95.45%,without statistical significance(P>0.05);there was also no statistical significance in the incidence of ADR (P>0.05). The costs of 2 groups were equal in addition to the cost of drugs. According to cost-minimization analysis,the drug cost of group A was 77.28 yuan and total cost was 705.88 yuan;the drug cost of group B was 1 310.40 yuan and total cost was 1 939.00 yuan;the drug cost and total cost of group A were far more less than that of group B,with statistical significance(P<0.05). The results of sensitivity analysis were consistent with it. CONCLUSIONS:The cost of Xiangdan injection is lower and more economical than that of Danshen chuanxiongqin injection in the treatment of unstable angina pectoris of coronary heart disease.

Objective To study the therapeutic and protective effect of low tidal volume(LTV) ventilation in children with acute respiratory failure.Methods Forty-eight patients with respiratory failure were enrolled in our study.The patients were suffered from severe infection,trauma or after major operation.Besides general treatments,they were all given ventilation with LTV.Blood gas,ventilation parameters and complications related to ventilation were also measured.Results No significant difference was found between the patients with high tidal volume(HTV) and those with LTV in the results of improving respiratory acidosis.But the incidence of(ventilated-)induced lung injury(VILI) was lower in LTV patients.Conclusion LTV ventilation is preferable for children with acute respiratory failure and beneficial for alleviation of VILI.

Objective To discuss the influence of blood exchange transfusions on hemato- microenvironment of neonates with hyperbilirubinemian.Methods Blood exchange transfusion was performed in 35 neonates.Mean transfusion volume was (136.9±27.4) ml/kg.The speed of blood exchange transfusion was 92 ml/(kg·h).Blood bilirubin,blood electrolyte,blood routine and blood sugar levels were measured before,during and after the transfusion.Results Serum total bilirubin (TB) decreased by 53.78% after blood exchange,but there was no change in Na~+,Cl~-,and blood sugar (P＞0.05),and K~+ was remarkably decreased from (4.45±2.40)mmol/L to (3.87±0.52)mmol/L (t=21.979,P＜0.05).TB,Hb,PLT,WBC,Ca~(2+) were decreased[TB from(511.52±80.21) μmol/L to (236.41±66.54) μmol/L;Hb from (145.20±11.70) g/L to (128.66±2.54) g/L;PLT from (207.84±70.67)×10~9/L to (134.86±48.61)×10~9/L;WBC from (16.90±10.56)×10~9/L to (8.94±7.44)×10~9/L,and Ca~(2+) from (1.26±0.32) mmol/L to (0.99±0.22) mmol/L,P＜0.05 or ＜0.01].Conclusions Blood exchange transfusion can not influence Na~+,Cl~-,and blood sugar,but has remarkable effect on total bilirubin,Ca~(2+),Hb,K~+,PLT,and WBC.

Objective To investigate and analyze the effect and insulin dosage of continuous subcutaneous insulin infusion(CSII) in type 2 diabetes.Methods 106 hospitalized patients with type 2 diabetes,who had poorly controlled blood glucose,were treated by insulin pump for 8 days,without oral hypoglycemic agents.The treatment days when blood glucose was well controlled and the insulin dosage at that time were observed.The related foctors for the therapeutic effects were analyzed.Results When blood glucose were well controlled,the mean time was 5.4±1.8 days,the(basal) insulin was 0.23±0.07(u/kg,day),the bolus before breakfest was 0.12±0.05(u/kg),the bolus before dinner was 0.14±0.06(u/kg),the bolus before supper was 0.14±0.06(u/kg).The dosage of insulin was decreased after blood glucose were well controlled.The frequency of hypoglycemia was 0.04±0.21(times/per patient),the frequency of biochemical hypoglycemia was 0.07±0.25(times/per patient) and reaction of hypoglycemia was 0.96±1.18(times/per patient).Conclusions The hyperglycemia of type 2 diabetes could be corrected by intensive insulin pump within 5-6 days.Multiple regression showed that fasting blood glucose and age were the factors that affect the time for blood glucose to be targeted.Duration of diabetes,fasting and postprandial blood glucose levels before treatment affect the required insulin dosage.

BACKGROUND:Autologous fat transplantation has been widely used in soft tissue defect repair and cosmetic surgery, and the 1-year transplant survival rate is 20%-80%. Therefore, the establishment of timely and adequate blood supply at early period after transplantation is very important for the survival of transplanted fat tissues.
OBJECTIVE:To observe the proliferation of human adipose-derived mesenchymal stem cel s transfected with vascular endothelial growth factor 165.
METHODS:Human adipose-derived mesenchymal stem cel s were subcultured in vitro. Recombinant adenovirus carrying vascular endothelial growth factor 165 and blank virus were respectively transferred into adipose-derived mesenchymal stem cel s. Cel s cultured normal y served as blank group.
RESULTS AND CONCLUSION:Compared with the control and blank groups, the expressions of vascular endothelial growth factor 165 mRNA and protein were higher in the experimental group (P<0.05). Experimental findings suggest that the recombinant adenovirus carrying vascular endothelial growth factor 165 transferred into adipose-derived mesenchymal stem cel s cannot only maintain the expression of target protein but also obviously promote the proliferation of adipose-derived mesenchymal stem cel s.
