Objective To evaluate the application of three dimensional conformal radiotherapy (3D-CRT) for non-small cell lung carcinoma (NSCLC) based on CT simulation in different respiratory phases in patients gaed≥70 years. Methods A total of 51 patients gaed≥70 years (range 70-88 years, mean age 73.5 years) with NSCLC were treated by 3D-CRT alone, using CT images of different respiratory phases. The case numbers at Ⅰb, Ⅱb, Ⅲa, Ⅲb and Ⅳstage were 3, 7, 19, 17 and 5, respectively. Both gross tumor volumes (GTV) at the end of inspiration and expiration were fused to a total GTV which was close to motorial range of tumor in respiration, and the expansion of clinical target volume/ planning target volume (CTV/PTV) need not include respiratory motion moreover. Compared with plans of classic 3D-CRT, the efficacy, prognostic factors and side effect of this treatment were evaluated. Results Compared with the traditional expansion of CTV/PTV, the volumes of PTV in this scheme were averagely 19.3% lower (median, 17.5%),and the volumes of lung that received equal dose to tumor were averagely 21.8% lower (median, 19.9%). The 1-, 2-and 3-years total survival rates were 70. 6%, 54.9% and 29.4% with a overall tumor response rate of 78.4%. KPS scores and node stages were independent prognostic factors, age was not. Conclusions CT simulations in different respiratory phases can effectively reduce PTV and improve the life quality without affecting the therapeutic effect in senile patients with NSCLC, and can be well tolerated.

OBJECTIVE:To investigate clinical efficacy and safety of different dosages of bromocriptine in the treatment pro-lactinoma,and its effects on serum prolactin(PRL)and tumor volume. METHODS:A total of 60 patients with prolactinoma were selected from our hospital during Jan.-Dec. 2015 as research objects,and then divided into group A and B according to random number table,with 30 cases in each group. Both groups were given Bromocriptine mesilate tablets orally during meal. Group A was given medicine with initial dose of 2.5 mg/d,increasing to 3.75 mg/d 3 d later,increasing by 2.5 mg every week after 2-3 d,and then recovering to 3.75 mg/d till serum PRL level had been controlled. Group B was given medicine with initial dose of 1.25 mg/d, increasing to 2.5 mg/d 3 d later,increasing by 1.25-2.5 mg every week after 2-3 d,and then recovering to 2.5 mg/d till serum PRL level recovered to normal. Both groups were treated for consecutive 3 months. Clinical efficacies as well as serum level of PRL and tumor size were observed in 2 groups,and the occurrence of ADR was recorded. RESULTS:The total response rate of group A (83.33％) was higher than that of group B (66.67％),without statistical significance (P>0.05). Before treatment,there was no statistical significance in serum level of PRL and tumor size between 2 groups (P>0.05). After 1,2 months of treatment,serum levels of PRL in 2 groups were decreased significantly,and the group A was significantly lower than the group B,with statistical significance(P<0.05). After 3 months of treatment,serum levels of PRL in 2 groups were decreased significantly compared to be-fore treatment,but there was no statistical significance between 2 groups(P>0.05). After treatment,tumor size of 2 groups were decreased significantly,and large adenoma and giant adenoma size in group A were significantly smaller than group B,with statisti-cal significance(P<0.05). There was no statistical significance in microadenoma size between group A and B(P>0.05). The inci-dence of ADR in group A(12 cases,40.00％)was significantly higher than group B(5 cases,16.67％),with statistical signifi-cance(P<0.05). CONCLUSIONS:Increasing dosages of bromocriptine no significant influence on therapeutic effect of prolactino-ma,but it can shorten the time of serum PRL level back to normal,and reduce the tumor size. The incidence of adverse reactions in-crease with the dosage.

Objective: To explore the influence of Aiweixin on cardiocyte apoptosis of myocardial ischemia-reperfusion injury in rats. Methods: Thirty male Wistar rats, 200-250g weight, were divided into 3 groups randomly: sham-operation group, Ischemia-reperfusion injury group (I/R) and Aiweixin preconditioning group, each group had 10 rats. The model of myocardial ischemia-reperfusion injury was established. The protein expressions of Bcl-2, Bax and Caspase-3 were studied by Immunohistch emicalstaining. Results:The protein expressions of Bax and Caspase-3 increased and Bcl-2 decreased signifi cantly (P

Objectives To find out the effects of estrogen and clomiphene on behavior of epileptic rats induced by kainic acid (KA) and probe into some mechanisms. Methods Ovariectomized Sprague-Dawley female rats were treated with estrogen (E) or estrogen and clomiphene (C). Their behaviors when they were induced seizures were observed and compared. Indirect immunofluorescence method was used to measure the alterations of gamma-aminobutyric acid (GABA) immunoreactive cells and ?1 subunits of GABA_A receptors in the hippocampus of all groups. Results The latency and time at reaching 4/5 degrees in KA+E group ((24.63?11.44) minutes and (41.50?16.22) minutes, respectively) were reduced greatly than KA group ((46.75?14.61) minutes and (65.13?12.99) minutes), while the latency of (KA+)E+C group (adding estrogen and clomiphene, (43.50?5.75) minutes) became prolonged significantly than in KA+E group. Conclusion High-level estrogen should be proconvulsant and the clomiphene might have some antiepileptic effects, which may be related with some alterations of GABA energic function in the brain.

Background and purpose:Colorectal carcinoma(CRC) is a major cause of cancer-related mortality. In the 1990s, several fi rst-line phase Ⅲ trails showed a signifi cant improvement in result with the addition of CPT-11(irinotecan, which is a specifi c inhibitor of topoisomerase Ⅰ) to FU-LV combination therapy(FOLFIRI).We observed the survival rate, effi cacy and adverse reaction of the combination chemotherapy of irinotecan plus folinic acid/continuous 5-? uorouracil bimonthly FOLFIRI regimen as second chemotherapy in treating advanced colorectal adenocarcinoma. Methods:Sixty patients with histologically proved advanced colorectal adenocarcinoma whose disease had progressed after treatment with first-line oxaliplatin or other chemotherapeutics agents were included to receive at least 2 cycles of chemotherapy with irinotecan 180 mg/m2 day 1 and folinic acid 200 mg/m2 iv,5-FU 400 mg/m2 iv bolus,days 1 and 2, 5-FU 600 mg/m2 iv infusion over 22 hours, days 1 and 2.Treatment was repeated every two weeks. Results:All patients were assessable for toxicity and 58 patients were evaluable for treatment response. The non-hematological toxicity was mild. Most was grade Ⅰ or Ⅱ. Only two patients experienced grade Ⅲ diarrhea and one patient experienced grade Ⅲ nausea and vomiting. There were no cases with grade Ⅳ toxicity. The most common hematological toxicity was neutropenia. Grade Ⅲ neutropenia were observed in fi ve patients. There was no case of febrile neutropenia. Based on intention to treat analysis, there were no complete responses (CR), 14(24.14%) partial response (PR), and 30 (51.72%) stable disease. the median time to disease progression was 6.09 months. The median overall survival was 9.65 months. Conclusions:Bimonthly irinotecan in combination with folinic acid and 5-fluorouracil was active with acceptable toxicities and a prolonged survival time in retreated colorectal cancer.

Objective To evaluate the effect of laparoscopic adrenalectomy for adrenal tumors by transperito-neal or retroperitoneal approaches. Methods Atotal of 41 laparoscopic adrenalectomy for adrenal tumor patients were pertormed,inchiding 16 patients by transperitoneal approach and 25 patients by retroperitoneal approach. The tumor size,operative time,intraoperative blood loss, postoperative hospital stay, postoperative ambulatory day and postopera-tive complications were observed. Results Of the 41 cases ,3 cases were transferred to open surgery and the other 38 cases were achieved successful operations. No significant differences( all P>0.05) were found in tumor size,intraop-erative blood loss, postoperative hospital stay, postoperative ambulatory day between the transperitoneal group and ret-roperitoneal group ,but there were significant differences( P<0.05) in operative time and intraoperative blood loss be-tween the two group. Conclusion Both the transperitoneal and retroperitoneal laparoscopic approaches are feasible and safe for adrenal tumors, and the latter has more advantages in operative time, but the operative approach still should be chosen based on the pathological changes,tumor size and position as well as the individual conditions of the patients.
