Invasion and metastasis are critical determinants on cancer morbidity.Genes and molecules participating in these steps have been demonstrated as potential prognostic factors.Growth factors and their receptors,cell-cycle regulators,cell-adhesion molecules and m trix-degrading enzymes are potentially used as prognostic factors.However,increased understandings for molecular mechanisms underlying carcinogenesis and its implementation in the treatment of gastric cancers have recently been focused on the development and incorporation of targeted agents with chemotherapy.

Objective To study the expression, distribution and significance of C2 gene in hepatocellular carcinoma (HCC) and gastric cancer tissue. Methods ABC immunohistochemical method was used to detect the expression of C2 protein in 60 samples of HCC tissue and 58 samples of gastric cancer tissue, and Western blot technique was used to detect the expression of C2 protein in 10 samples of HCC tissue and pericancerous tissue. Results 1. Expression of C2 protein in HCC tissue: in 60 samples of HCC and 42 samples of pericancerous tissue, the positivity rate of C2 protein was 27.3% and 83.3%, respectively. The positivity rate of C2 protein was significantly higher in pericancerous tissue than that in HCC tissue ( P

Objective To evaluate the therapeutic effect of 89 Sr internal radiotherapy on multiple-bone metastasis of cancer. Methods Forty-nine cancer patients with multiple-bone metastasis received 89 Sr internal radiotherapy. The pain control effect, life quality improvement, change in levels of blood calcium and serum alkaline phosphatase (ALP), and side effects were analyzed respectively. Results The total effective rate of pain control was 77.6 %. The life quality was improved obviously. The levels of blood calcium and ALP were decreased. No obvious side effects were found during the treatment. Conclusion 89 Sr internal radiotherapy had a good therapeutic effect on multiple-bone metastasis of cancer.

This article summarized the regular patterns, features and advantages of Professor Yu Hai-Bo's acupuncture-moxibustion therapy for hemorrhoids, in order to guide the acupuncture treatment for hemorrhoids.

Objective To investigate the multiple factors correlated to femoral head necrosis in patients over 45 years old with femoral neck fractures after closed reduction and cannulated screws fixation.Methods Three hundred patients with femoral neck fracture were admitted from May 1999 to May 2004 and treated by closed reduction and internal fixation with cannulated screws.We analyzed the multiple factors:age,gender,Garden classification,follow-up time,procedure delay,quality of reduction,time of full-weight-loading,fixation removal, and preoperative traction.Multiple correlation factors were analyzed by SPSS10.0 statistic system.Results Complete case records were documented in 99 cases who were followed up for an average of 24.5 months(range,8 to 60 months).Femoral head necrosis occurred in 15 cases(15.2%).Time of femoral head necrosis was 8 to 50 months after operation.The combination of quality of reduction,preoperative traction,age,and age?fixation re- moval was found to have the most significant influence on femoral head necrosis after internal fixation for femoral neck fractures.Conclusions Good reduction is the most important factor correlated to the outcome of a femoral neck fracture.Age is linked to the risk of necrosis but it is relatively insignificant.Preoperative traction in wrong positions can increase the incidence of necrosis.Garden classification is important in predicting femoral head necrosis and is associated with quality of reduction,but it is not a risk one in the combination of multiple correlation factors that lead to the necrosis.

Objective To evaluate the status of the morbidity of serum lipids in Beijing through the detection of serum lipids in health checking adults.Methods The serum total cholesterol(TC),low density lipoprotein cholesterol(LDL-C),high density lipoprotein cholesterol(HDL-C)and triglyceride (TG)were detected by chemistry test in 13 336 adults,and age-adjusted prevalence of dyslipidemia and its distribution in different sexes and age groups were statistically analyzed.Results The prevalence of total dyslipidemia is 59.9%,71.6 % in male and 47.2% in female.The prevalence of the four components of serum lipids raised with age in both sex(P

Objective To observe the clinical effect of dexmedetomidine combined with butorphanol in preventing tourniquet reaction.Methods Fifty patients(ASA Ⅰ-Ⅱ)with upper limb operation and satisfactory effect of brachial plexus block were randomly divided into the dexmedetomidine group(A)and dexmedetomidine combined with butorphanol group (B),25 cases in each group.The anesthesia drug preparation method in the group A:dexmedetomidine 200μg was added with normal saline 50 mL;in the group B:dexmedetomidine 200 μg,butorphanol 1 mg and normal saline 50 mL altogether.The group A used dexmedetomidine 1 μg/kg load for 15 min and maintained by 0.4 μg · kg-1 · h-1 until the end of operation;the group B was given 0.015 mg/kg butorphanol,then was given medication according the scheme of group A.The VAS score,BIS value,Remsay sedation score,HR,MAP and SPO2 were recorded at the time points:before medication (T0),immediately after the tourniquet inflation (T1),15 min (T2),30 min (T3),45 min (T4),60 min after tourniquet inflation (T5) and 10 min after deflation (T6).The subjective response classification count,respiratory depression,bradycardia and hypotension in the two groups were assessed.pH,PaO2,PaCO2,HCO3-and LAC at T6 were evaluated by theblood gas analysis.Results The VAS score,BIS value,Ramsay sedation score,HR and MAP at T4,T5 had statistical difference between the two groups (P＜0.05).In the group A,the good and poor subjective responses had 9 cases and 4 cases respectively,which in the group B had 13 cases and 1 case,the difference was statistically significant (P＜0.05);there was no respiratory depression,bradycardia and hypotension in the two groups;the blood gas analysis showed no statistical difference between the two groups.Conclusion Applying dexmedetomidine combined with butorphanol in upper and lower limb surgery under brachial plexus anesthesia can significantly prevent the tourniquet reaction,its effect is superior to single use of dexmedetomidine.
