OBJECTIVE:To observe the clinical efficacy and safety of recombinant human endostatin (rh-endostatin) combined with Lobaplatin for injection and irinotecan injection in the treatment of advanced recurrent small cell lung cancer (SCLC). METHODS:A total of 88 patients with advanced recurrent SCLC in our hospital were divided into control group (41 cases) and observation group (47 cases) according to random number table. Control group was given Irinotecan injection+Lobaplatin for injection. Observation group was additionally given Recombinart human endostatin injection 15 mg added into 0.9%Sodium chloride injection 250 mL,ivgtt,qd,for consecutive 14 d,every 14 d. A treatment course lasted for 28 d,and both groups were treated for 2 courses. The clinical efficacy,the levels of serum carcinoembryonic antigen(CEA),the scores physical state (ECOG) and quality of life (QOL) before,after treatment were observed in the two groups,and the survival and adverse reactions of the two groups were compared. RESULTS:The total response rate of observation group was 59.6%,which was higher than 43.9% of control group,but there was no statistical significance (P>0.05). Before treatment, there was no significant difference in serum CEA levels,ECOG scores or QOL scores,between 2 groups(P>0.05);after treatment,the serum CEA levels of the two groups were significantly decreased,and the observation group was significantly lower than the control group,with statistically significant (P<0.05). In observation group,ECOG scores decreased while QOL scores increased significantly,and significantly better than the control group,with statistical significance(P<0.05). The overall survival(OS)of observation group was 16.8 months,which was significantly higher than 11.5 months of control group,with statistical significance (P<0.05). The incidence of leucopenia in observation group was significantly higher than control group;the incidence of leucopenia and abnormal liver function were significantly lower than control group,with statistical significance(P<0.05). CONCLUSIONS:Rh-endostatin injection combined with lobaplatin and irinotecan can improve serum CEA levels and the quality of living aswell as prolong the survival time.

OBJECTIVETo evaluate the effects of Shenfu Injection (SF) on cytokines during cardiopulmonary bypass (CPB) in infants.

METHODSTwenty-four infants with congenital heart disease, aged below three years, were randomly assigned to the control group and the SF group equally. In the SF group, 1 mL/kg of SF was given through center vein pump after center vein puncture being performed, while only normal saline was given instead in the control group. Blood sample was obtained for measurement of serum necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) concentration by ELISA, at various time points in the process, i.e. right after anesthesia induction (T1), beginning of CPB (T2), aortic off-clamping (T3), 20 min after CPB (T4), the end of CPB (T5), and 6 h (T6) and 24 h (T7) after CPB.

RESULTSThe time for reverting to sinus heart rhythm and analepsia after CPB was shorter in the SF group than in the control group (P < 0.05). Serum concentration of TNF-a and IL-6 was equal in the two groups at T1; they increased significantly after CPB (P < 0.05), reached the peak value at T4 and reduced to the normal level at T7 in the control group. TNF-alpha concentration was significantly lower at T3, T4 and T5, and IL-6 concentration was lower at T4 in the SF group than that in the control group at corresponding time point (P < 0.05).

CONCLUSIONSF could shorten the time for reverting to sinus heart rhythm and analepsia after CPB in infants, and suppress the inflammatory response caused by CPB.

Background and purpose:The young breast cancer patients were treated with goserelin without individualized regimen, and lack of available clinical marker. The aim of this study was to investigate the role of anti-Müllerian hormone (AMH) in evaluation of individualized treatment of ovarian function suppression in the young breast cancer patients.Methods:Forty-one young patients with estrogen receptor (ER) and progesterone receptor (PR) positive breast cancer from May 2012 to Jan. 2014 were randomly divided into 2 groups to undergo radical resection of breast cancer. According to postoperative treatment, one group was treated with goserelin + chemotherapy (n=20), and the other group received chemotherapy alone (n=21). Thirty female patients in the same age group were selected as normal control group. The time of menopause and menstrual recovery after the goserelin + chemotherapy or chemotherapy alone were observed in 2 groups. In early follicular phase (day 3-5) of the cycle preceding the operation and 3, 6 courses after the goserelin + chemotherapy treatment or chemotherapy treatment, serum levels of AMH, FSH and E2 were measured in 2 groups. Accordingly, serum levels of AMH, FSH and E2 were evaluated as well in normal control group.Results:There were no signiifcant differences in preoperative general conditions and preoperative serum FSH and E2 levels among the 3 groups (P>0.05). Compared with normal control group, the preoperative serum AMH levels of young breast cancer patients were decreased signiifcantly (P=0.04). The menopause time and menstrual recovery time in 2 chemotherapy groups were signiifcantly shorter than that in normal control group (P=0.00). Compared with normal control group and preoperative measurement, the differences in serum FSH and E2 levels were not statistically significant in goserelin + chemotherapy group or chemotherapy alone group (P<0.05). The serum AMH levels measured at different time points of the goserelin + chemotherapy group and chemotherapy alone group were decreased signiifcantly (P<0.05). Compared with the chemotherapy group, the serum AMH levels of the goserelin + chemotherapy group after 6 courses were signiifcantly decreased, and then signiifcantly increased 6 months after menstrual recovery (P<0.05).Conclusion:This study demonstrated that the serum AMH levels were obviously decreased after the ovarian function suppression treatment and increased after the menstrual recovery compared with evaluation of other ovarian reserve index. The serum AMH level could suggest ovarian reserve damage even after ovarian function has recovered to the noticeable level. Thus, AMH could be used clinically to evaluate the ovarian reserve of breast cancer patients as a potential marker for the individualized ovarian function suppression treatment in young breast cancer patients.
