Objective To observe the efifcacy and safety of XELOX plus bevacizumab as a ifrst-ine treatment for Chinese patients with metastatic colorectal cancer. Methods In this study, we retrospectively reviewed cases in which XELOX plus bevacizumab were administered in order to evaluate its efifcacy and safety in clinical practice.In total, 40 patients with mCRC who presented at Fuchu Hospital received XELOX plus bevacizumab as a ifrst?line treatment from September, 2009 to April, 2012. Eligible patients had histologically conifrmed mCRC. XELOX consisted of a 2-h intravenous infusion of oxaliplatin 130 mg/m 2 on day 1 plus oral capecitabine 1,000 mg/m 2 twice daily for two weeks of athree?week cycle. Overall survival (OS) and survival benefit were analyzed when patients continued with XELOX plus bevacizumab beyond disease progression. Results The median progression?free survival (PFS) was 290 days [95%conif-dence interval (CI):222?409 days] and the median OS was 816 days (95%CI:490?842 days). The response rate (RR:complete plus partial response) was 67.5%, and the disease control rate (RR plus stable disease) was 90%. Conclusion XELOX plus bevacizumab may be considered a routine ifrst?line treatment option for patients with mCRC.

Objective To investigate the effect of oxaliplatin combined with capecitabine on the rate of local control and anal sphincter preservation of rectal cancer.Methods Eighty patients with stage Ⅱ/Ⅲ colorectal adenocarcinoma were randomly divided into control group and observation group,each group in 40cases.The patients in the observation group were treated with oxaliplatin and capecitabine.The control group was treated with oxaliplatin combined with leucovorin and 5-fluorouracil.The patients were followed up for 2~4 weeks.The local curative effect, perioperative biochemical index,R0 (excision margin without cancer cell) resection rate and sphincter preserving rate were compared between the two groups.Results In the control group, the short-term curative effect was 47.50%, which in the observation group was 60.00%, the difference was statistically significant (x2=4.22,P<0.05).There were no statistically significant differences in the biochemical indicators between the two groups (all P>0.05).The R0 resection rates of the control group and the observation group were 62.50%,57.50% (x2=0.67,P>0.05).The anal sphincter preservation rates of the control group and observation group were 32.50%,37.50% respectively (x2=0.67,P>0.05).The local control rates of the control group and observation group were 90.00%,92.50%,which of the observation group was higher than the control group, but the difference was not statistically significant(x2 =0.32,P>0.05).Conclusion The combination of oxaliplatin and capecitabine can improve the local curative effect in patients with rectal cancer without affecting the biochemical indicators of perioperative patients, but the effect of R0 resection rate and preserving anus rate in patients with rectal cancer compared with the chemotherapy regimen of FOLFOX4 has no significant difference, it is worthy of clinical promotion.

OBJECTIVE:To investigate the application of antibacterials in patients with chronic obstructive pulmonary disease(COPD)in our hospital.METHODS:A retrospective analysis was performed on 77 COPD inpatients with respect to the varieties of antibiotics,DDDs,drug costs,routes of administration,medication duration,combined use of antibiotics,therapeutic outcome,bacterial culture and susceptibility test,adverse drug reactions(ADR)and irrational drug use etc.RESULTS:100% of the patients received antibacterials.Topping the first five places on the DDDs list were levofloxacin,cefuroxime,amoxicillin/clavulanate potassium,ceftazidime and azithromycin.The combined use of two kinds of antibiotics accounted for 77.65% versus 2.35% of three kinds concomitantly.CONCLUSION:The use of antibacterials in COPD patients in our hospital is basically rational;however,the indications of antibacterials for COPD patients should be followed strictly toachieve rational and standard drug use.

Objective To observe the real-time effect of retaining needle at Lingtai (GV 10) and Shendao (GV 11) on ST-T segment on cardiogram in patients with angina pectoris of coronary heart disease (CHD).Method Thirty patients with angina pectoris of CHD who received acupuncture at Lingtai (GV 10) and Shendao (GV 11) were divided into group A with needles retained after insertion of the needles and group B without needles retained. The two groups were observed by using 12-lead electrocardiogram (ECG) before and after treatment, to compare the ST segment and T wave atⅡ,Ⅲ, avF lead and V4, V5, V6lead before and after treatment.Result After treatment, ST segment atⅡ,Ⅲ, avF lead and V4, V5, V6lead was changed significantly in group A (P<0.05). T wave was significantly changed atⅡ,Ⅲ, avF lead after treatment in group A (P<0.05). T wave at V4, V5, V6 lead was significantly changed after treatment in both groups (P<0.01,P<0.05).Conclusion Acupuncture at Lingtai (GV 10) and Shendao (GV 11) can improve myocardial ischemia in angina pectoris of CHD; compared to acupuncture without needles retained, retaining needles after acupuncture can produce a more significant effect in improving the inferior and anterior myocardial walls and a better real-time effect on ST-T on ECG of angina pectoris of CHD.
