Chinese Journal of Sports Medicine 2001;20(1):19-23
The purpose of this study is to investigate the effects of phospholipids supplementation on nutritional status and antioxidant status of trained mice. The results indicate that: 1)In phospholipids supplementation groups concentrations of Hb and serum phospholipid increase significantly, serum Alb concentration tends to increase.Phospholipids supplementation can also help the recovery of Hb which is decreased after exhaustive exercise.2)Phospholipids supplementation can improve antioxidative status in some tissue .3)The activity of SOD is highest in quadriceps while the activity of GPX is highest in liver, and concentration of MDA is lowest in kidney.Different kinds of tissue show different levels of SOD, GPX and MDA, indicating their different abilities of antioxidation.4) Phospholipids supplementation have no effect on body weights of trained mice.

Objective To observe the clinical efficacy of acupuncture plus auricular point sticking in treating polycystic ovary syndrome (PCOS). Method A total of 80 PCOS patients were randomly divided into a treatment group of 40 cases and a control group of 40 cases. The treatment group was intervened by acupuncture plus auricular point sticking, while the control group was intervened by acupuncture only. The clinical efficacy was observed in the two groups after 3 treatment courses. Result The menstrual condition and basal body temperature (BBT) were compared in the two groups before and after the treatment. The menstrual condition and BBT in the treatment group were significantly improved (P<0.01); the menstrual condition was improved (P<0.05) and the BBT condition was significantly improved in the control group (P<0.01). The total effective rate was 82.5% in the treatment group, significantly different from that in the control group (P<0.05). Conclusion Acupuncture plus auricular point sticking can produce a satisfactory efficacy in treating PCOS.

AIM:To introduce the concept of bridging study and its strategies in clinical trials for new drug application.METHODS:The concept of bridging study proposed in the ICH E5 guideline was introduced,with a case using bridging strategies in the new drug applications(NDAs)approved by the regulatory authority in Japan.The concrete mode and the development of bridging studies in Asia were summarized.RESULTS:With the application of the ICH E5,some countries and regions have successfully used the bridging strategy in the new drug applications.The bridging strategy is becoming a common and practical basis for the decision making of marketing approvals of new drugs in the Asia-pacific country.CONCLUSION:The currently bridging studies in Asia will play an important role in the extrapolation of foreign clinical data in new drug application.Using bridging study is very helpful in judging ethnic differences of drugs,reducing duplication of clinical trails,as well as shortening clinical development periods.

Objective To study the effects of DHPs calcium antagonist Mn9202 and lacidipine on 5-HT、TH and 5-HTR of rat stomach fundus smooth muscle cells. Methods It's effects was investigated by using immunocytochemistry and image analysis of stom- ach fundus smooth muscle cells in culture and compared with cyprohetadine(antagonist of 5-HT). Results 5-HT、TH and 5-HTR im- munoreactive substances were existed in SFSMC. The results of image analysis indicated that the content of 5-HT. TH and 5-HTR were significantly lower when using Mn9202.lacidipine and cyprohetadine. Conclusion The results suggest that the rat stomach fundus smooth muscle cells possess 5-HT autocrine function, and DHPs calcium antagonist reduce the number of 5-HT receptor in the rat stomach fundus smooth muscle cells though the reduction of 5-HT sythesis, this results conform with cyprohetadine (antagonist of 5 - HT).

Purpose:
We aimed to evaluate whether the addition of pemetrexed is effective in improving progression-free survival (PFS) in epidermal growth factor receptor (EGFR)–mutated patients with or without concomitant alterations.
Materials and Methods:
This multicenter clinical trial was conducted in China from June 15, 2018, to May 31, 2019. A total of 92 non–small cell lung cancer (NSCLC) patients harboring EGFR-sensitive mutations were included and divided into concomitant and non-concomitant groups. Patients in each group were randomly treated with EGFR–tyrosine kinase inhibitor (TKI) monotherapy or EGFR-TKI combined with pemetrexed in a ratio of 1:1. PFS was recorded as the primary endpoint.
Results:
The overall median PFS of this cohort was 10.1 months. There were no significant differences in PFS between patients with and without concomitant and between patients received TKI monotherapy and TKI combined with pemetrexed (p=0.210 and p=0.085, respectively). Stratification analysis indicated that patients received TKI monotherapy had a significantly longer PFS in non-concomitant group than that in concomitant group (p=0.002). In concomitant group, patients received TKI combined with pemetrexed had a significantly longer PFS than patients received TKI monotherapy (p=0.013). Molecular dynamic analysis showed rapidly emerging EGFR T790M in patients received TKI monotherapy. EGFR mutation abundance decreased in patients received TKI combined chemotherapy, which supports better efficacy for a TKI combined chemotherapy as compared to TKI monotherapy. A good correlation between therapeutic efficacy and a change in circulating tumor DNA (ctDNA) status was found in 66% of patients, supporting the guiding role of ctDNA minimal residual disease (MRD) in NSCLC treatment.
Conclusion
EGFR-TKI monotherapy is applicable to EGFR-sensitive patients without concomitant alterations, while a TKI combined chemotherapy is applicable to EGFR-sensitive patients with concomitant alterations. CtDNA MRD may be a potential biomarker for predicting therapeutic efficacy.
