Through analyzing the every textual research literature on the origin of the location method of ashi points, it is pointed out that the location method of ashi points has been generalized. It is known through systematic research and theoretical identification that this method refers to the simple way to locate the points, originated from the folk, and it is widely used to find the sites for pain relief when compared to the official education of meridians and acupoints, as well as treatment. At the time with the shortage of medical services and supplies, the poor people had no alternative, which results in a certain limitation. Modern acupuncture practitioners must associate ashi points with the acupoints of fourteen meridians and the extraordinary points in clinical practice, and deepen the exploration with modern medical knowledge and technology adopted.

Non-small cell lung cancer （NSCLC） is a malignant tumor of the respiratory system with a high incidence. The early symptoms are not typical， and most patients are diagnosed at an advanced stage， which seriously threatens the lives and health of people. Surgery， chemotherapy， and targeted therapy are the main means of treatment at present， but the consequent drug resistance and adverse reactions restrict these treatment methods with certain limitations. In recent years， with the development of traditional Chinese medicine （TCM） in tumor resistance， TCM has attracted extensive attention for its obvious therapeutic effect and fewer adverse reactions. Numerous signaling pathways are involved in the formation and development of NSCLC， where phosphatidylinositol 3 kinase （PI3K）/protein kinase B （Akt）/mammalian target of rapamycin （mTOR） signaling pathway is one of the key regulatory pathways. The PI3K/Akt/mTOR signaling pathway affects the proliferation， invasion， and metastasis of NSCLC cells by affecting the cycle， inhibiting the apoptosis， inhibiting the autophagy of tumor cells， and promoting tumor neovascularization. As revealed by the recent literature， Chinese medicine plays an indispensable role in NSCLC cell autophagy， cell cycle， apoptosis， invasion and metastasis， neovascularization， and reversal of drug resistance by regulating the PI3K/Akt/mTOR signaling pathway. Although some Chinese medicinal extracts or compounds have made great breakthroughs in some mechanisms of action in the treatment of NSCLC， these studies only remain at the level of in vitro cell experiments and animal studies in vivo. Researchers are faced with the great challenge of "transforming the research results of Chinese medicines into clinical applications". Based on the current research status in China and abroad， this paper reviewed Chinese medicine in the intervention in NSCLC through the regulation of PI3K/Akt/mTOR signaling pathway in recent years， in order to open up new ideas for NSCLC drug therapy research and also provide a useful reference for further mechanism research.

Objective:To analyze the distribution of ages at the interhospital transfer of outborn very preterm infants in China and to compare their perinatal characteristics and outcomes at discharge and neonatal intensive care unit (NICU) treatment.Methods:A total of 3 405 outborn very premature infants with a gestational age of 24-31 +6 weeks who were transferred to the NICUs of the Chinese Neonatal Network (CHNN) in 2019 were included in this retrospective study. According to the age at transfer, they were divided into three groups: early transfer (≤1 d), delayed transfer (>1-7 d) and late transfer (>7 d) groups. Analysis of variance, t-test, Chi-square test (Bonferroni correction), Kruskal-Wallis test and Wilcoxon rank-sum test were used to compare the general clinical condition, treatment, and outcomes at discharge among the three groups. Results:The median gestational age was 29.7 weeks (28.3-31.0 weeks) and the average birth weight was (1 321.0 ± 316.5) g for these 3 405 infants. There were 2 031 patients (59.6%) in the early transfer group, 406 (11.9%) in the delayed transfer group and 968 (28.4%) in the late transfer group. Infants who received continuous positive airway pressure ventilation and tracheal intubation in the delivery room accounted for 8.4% (237/2 806) and 32.9% (924/2 805), respectively. A total of 62.7% (1 569/2 504) of the mothers received antenatal glucocorticoid therapy and the ratio in the early transfer group was 68.7% (1 121/1 631), which was higher than that in the delayed transfer group [56.1% (152/271), χ2=16.78, P<0.017] and the late transfer group [49.2% (296/602), χ2=72.56, P<0.017]. The total mortality rate of very premature infants was 12.7% (431/3 405), and the mortality rates in the early, delayed and late transfer groups were 12.4% (252/2 031), 16.3% (66/406) and 11.7% (113/968), respectively ( χ2=5.72, P=0.057). The incidences of severe intraventricular hemorrhage, late-onset sepsis, necrotizing enterocolitis, and bronchopulmonary dysplasia at the corrected gestational age of 36 weeks or discharge were all higher in the delayed and late transfer groups than in the early transfer group, respectively. The incidences of retinopathy of prematurity, retinopathy of prematurity requiring treatment and bronchopulmonary dysplasia at the corrected gestational age of 36 weeks or discharge in the late transfer group were significantly higher than that in the delayed transfer group (Bonferroni correction, all P<0.017). In the late transfer group, the median age of very premature infants at discharge was 66.0 d (51.0-86.0 d), and the corrected gestational age at discharge was 38.9 weeks (37.1-41.2 weeks), and both were greater than those in the early transfer [48.0 d (37.0-64.0 d), Z=260.83; 36.9 weeks (35.7-38.3 weeks), Z=294.32] and delayed transfer groups [52.0 d (41.0-64.0 d), Z=81.49; 37.4 weeks (36.1-38.7 weeks), Z=75.97] (all P<0.017). Conclusions:Many very premature infants need to be transferred to higher-level hospitals after birth. The later the very premature infants are transferred, the higher the incidence of complications will be. It is suggested that intrauterine or early postnatal transport may improve the prognosis of very premature infants.

Objective:To analyze whether the application of growth hormone (GH) in the frozen-thawed embryo transfer (FET) cycle can improve the pregnancy outcome of patients.Methods:The retrospective cohort study including 1042 FET cycles was carried out between January 2015 to July 2018 in Reproductive Medicine Center,the Fourth Hospital of Hebei Medical University. According to medication before transfer, all patients were divided into GH group (group A ) and no GH group (group B). The pregnancy outcomes were compared between the two groups in aged patients (≥35 years), polycystic ovary syndrome (PCOS) patients and repeated implantation failure (RIF) patients.Results:In group A, the maternal age [(31.1±4.5) years old] and the clinical pregnancy rate [67.1% (114/170)] were higher than those in group B [(30.1±4.4) years old, 57.5% (501/872)]( P=0.010, P=0.020). There were no significant differences in the implantation rate, the clinical pregnancy rate, the abortion rate and the live birth rate between group A and group B in aged patients (all P>0.05). In PCOS patients, the live birth rate in group A [65.8% (25/38)] was significantly higher than that in group B [42.3% (96/227)] ( P=0.007). In the RIF patients, the implantation rate [37.3% (57/153)], the clinical pregnancy rate [50.5% (46/91)] and the live birth rate [37.4% (34/91)] in group A were significantly higher than those in group B [23.0% (115/501), 29.1% (92/316), 21.8% (69/316)] ( P<0.001, P<0.001, P=0.003). Conclusion:For the aged patients, adding GH could not improve pregnancy outcomes. The application of GH in PCOS patients could increase the live birth rate. For the RIF patients, the application of GH could increase the implantation rate, the clinical pregnancy rate and the live birth rate.
