Imatinib is an effective tyrosine kinase inhibitor, used in the treatment of advanced or inoperable gastrointestinal stromal tumors. Despite its efficacy, resistance is often developed among a portion of patients. Resistance to imatinib can be divided into primary and secondary resistance, with the latter becoming the focus of many recent researches. Research on the mechanisms of secondary resistance may lead to the identification of novel therapeutic strategies.

Dyslipidemia is one of the major risk factors for cardiovascular disease in elderly,but clinical practices in the management of elderly dyslipidemia are still not satisfactory.The cornerstone of treatment for elderly dyslipidemia consists of therapeutic lifestyle change and statins.Recent guidelines emphasize aggressive low density lipoprotein-cholesterol control with statins.However,intensive statin therapy may increase the risk of myopathy and diabetes.Therefore,it is important to consider risk benefit ratio in individual patients.The additional benefit of statins in combination with other hypolipidemic drugs on cardiovascular risk still needs verifying by further investigation.

Objective To investigate the role of zenapax in the prevention of acute rejection in renal transplant recipients.Methods The medical records of 50 renal transplant recipients treated with one dose of zenapax(study group) and simultaneously 30 renal transplant recipients without treatment of zenapax(control group) were retrospectively analyzed.The follow-up was six months.The incidence of acute rejection,renal allograft function,infection,and adverse effects of zenapax were comparatively analyzed between the 2 groups.Results Acute rejection rate was lower in study group(13/50,26%) compared with that in control group(17/30,57%;P)(0.05)).Conclusions One dose regimen of zenapax as part of immunosuppressive therapy is effective in the prevention of acute rejection in renal transplant recipients.It has less side effects and contributes to the improvement of renal allograft function.

Objective To analyze the occurrence rate,positive rate,and other related factors influencing interpectoral lymph nodes in breast cancer patients,and to explore the significance and indications of the surgical dissection of interpectoral lympy nodes.Methods Clinical and pathological data from 148 breast cancer patients were retrospectively analyzed.All patients were subjected to modified radical mastectomy,and interpectoral lympy nodes were pathologically examined.The occurrence rate and metastasis of interpectoral lympy nodes were recorded,and the relationship between the interpectoral lympy nodes positive rate and tumor size,axillary nodes,clinical stages,neo-adjuvant chemotherapy,hormone receptors,human epidermal growth factor receptor-2 (Her-2) expression,and molecular subtypes of breast cancer were determined.Results The occurrence rate,overall metastasis rate,and the positive rate of interpectoral lympy nodes in patients with axillary lymph node metastasis were 13.5％(20/148),4.7％(7/148),and 10.9％ (7/64),respectively.I nterpectoral lympy nodes metastasis was significantly correlated with axillary node metastasis and clinical stages (P＜ 0.05).However,interpectoral lympy nodes metastasis was not significantly related with hormone receptor and Her-2 expressions(P ＞ 0.05).Interpectoral lympy nodes metastasis rate was not affected by neo-adjuvant chemotherapy.Patients with interpectoral lympy nodes metastasis were characterized by larger tumors,more positive axillary lymph nodes,and later chnical stages.Conclusions Interpectoral lympy nodes metastasis usually occurs in patients with larger tumors,more positive axillary lymph nodes,later clinical stages,as well as those with locally advanced cancer that meets the standard of neo-adjuvant chemotherapy.These indications suggest that the surgical dissection and pathological examination of interpectoral lymph nodes should be routinely performed.

Objective To investigate the concentration of procalcitonin,C-reactive protein and WBC count for patients with dif-ferent kind of bacterial infection.Methods 49 blood samples and 81 other samples were collected form different patients for bacteri-al culture.Meanwhile,procalcitonin,C-reactive protein concentration and WBC count of those patients were determined to find whether these indicators exhibited any difference between Gram-positive and Gram-negative bacteria infected patients.Results For bloodstream infection,PCT levels in patients with Gram-nagetive bacterial infection were obviously higher than those with Gram-positive infection(P <0.05 ).For other infection,there was no statistical difference among patients′PCT,CRP concentration and WBC count(P >0.05).Conclusion PCT concentration is valuable in the differential diagnosis of blood stream infection caused by Gram-negative and Gram-positive bacteria,but not in local infection infection.

Objective To observe the clinical efficacy of micro-invasive point-through-point thread-embedding in treating acute stage of post-stroke shoulder-hand syndrome. Method Sixty patients were randomized into a treatment group and a control group, 30 in each group. Patients in the treatment group were intervened by micro-invasive point-through-point thread-embedding in addition to rehabilitation training, while patients in the control group were by rehabilitation training alone. Before treatment and after 4-week treatments, Visual Analogue Scale (VAS) was used to estimate shoulder pain, modified Barthel Index (MBI) to detect the activities of daily life, and Fugl-Meyer Assessment Scale to measure the motor function of upper limb. Result Before treatment, there were no significant differences in comparing the involved indexes between the two groups (P>0.05), and the indexes were significantly improved after intervention in both groups (P<0.05). Conclusion Micro-invasive point-through-point thread-embedding can reduce pain intensity, improve the activities of daily life and motor function of upper limb of patients in acute stage of post-stroke shoulder-hand syndrome.

The penal stipulation to the subject range about crime of illegal medical practice is too narrow,and there is also a great deal of contradictory regulation between Criminal Law and Practicing Physicians Law so it can not achieve the legislation goal.It is essential to revise the 1st section of "Criminal law "336th in order to expand the subject range and standardize the medical service market of our country.
