Radiation-induced lung injury is a prevalent side effect of radiotherapy for chest cancer. The "three phases and three methods "is an innovative theory based on the evolution of the core pathogenesis of radiation-induced lung injury. Its formation also considers the understanding of radiation-induced lung injury by ancient and modern medical practitioners, pathological characteristics, clinical manifestations, and the development patterns of radiation-induced lung injury. The "three phases and three methods" refers to the three phases of the course and the three treatment methods. The core pathogenesis of radiation-induced lung injury from the beginning, middle and late stages is heat toxicity, yin deficiency, and blood stasis. Therefore, the course of radiation-induced lung injury is divided into three phases: blazing heat toxin, yin deficiency and heat accumulation, and static blood obstruction. The method of clearing the lung and resolving toxins, enriching yin and venting heat, invigorating blood and dissolving stasis are used respectively. Traditional Chinese medicines commonly used in each phase include Flos Lonicerae, Atrina Glass, heartleaf houttuynia herb, Radix Ophiopogonis, American Ginseng, Forsythiae Fructus, Radix Salviae Miltiorrhizae, Rhizoma Ligustici chuanxiong, Scorpio, etc. This article presents the theoretical origins of the "three phases and three methods" concept by reviewing of ancient literature, inheriting experience, and summarizing disease pathogenesis, as well as elaborating on the academic connotations of the "three phases and three methods". The scientific validity of the "three phases and three methods" is verified by literature, clinical, and basic research. The "three phases and three methods" interprets the core characteristics of each stage of radiation-induced lung injury, improves the traditional Chinese medicine prevention and treatment system for radiation-induced lung injury, and provides theoretical basis for achieving complete process management.

Objective:To observe the effect of electroacupuncture at the Shuigou point on systolic phenotype-related factors and on the JAK1/STAT3 signaling pathway of the middle cerebral artery smooth muscle cells in rats modeling cerebral infarction; and to explore the molecular mechanism of treating cerebral infarction with electroacupuncture.Methods:A total of 108 healthy male Wistar rats were randomly divided into a blank group ( n=6), a sham operation group ( n=6), a model group ( n=48) and an electroacupuncture group ( n=48). The model and electroacupuncture groups were randomly divided into eight phase subgroups at 1h, 3h, 6h, 12h, 24h, 72h, 7d and 14d after the modeling of middle cerebral artery occlusion (MCAO), with six rats in each group. The electroacupuncture groups received electric acupuncture at the Shuigou acupoint for 20min after successful modeling. Neurological Severity scoring (NSS) was used to evaluate the neurological impairment. PLN protein expression in the middle cerebral artery and the expression of JAK1 and STAT3 proteins in the rats′ brain tissue were detected using western blotting. PDGF-AA content in the middle cerebral artery was measured using enzyme-linked immunosorbent assays. Results:Compared with the blank and sham operation groups, the average NSS score and PDGF-AA protein expression had increased significantly in the model and electroacupuncture groups. PLN protein expression had decreased significantly at 12h-14d in the model group, but decreased significantly at 12h-7d in the electroacupuncture group. Compared with those two groups, there was a significant increase in JAK1 protein expression at 1h-72h, 3h-6h, 24h-72h, and14d in the model group. In the electroacupuncture group the corresponding significant increases were over 1h-14d, 1h-6h, 24h, 72h, and 14d. STAT3 protein expression had increased significantly in the model group over 6h-14d and 3h-14d. In the electroacupuncture group those increases were over 6h-14d. Compared to the model group, a significant increase was observed in the expression of PLN protein at 14d, with a significant decrease in NSS at 72h, 7d and 14d. PDGF-AA protein had increased significantly at 6h-7d. For JAK1 protein that was at 12h and 14d, and for STAT3 protein it was over 12h-72h and at 14d.Conclusion:Electroacupuncture at the Shuigou point may regulate the expression of PDGF-AA and the JAK/STAT signaling pathway so as to regulate the normal expression of PLN, and thus smooth muscle contraction to maintain the normal functioning of the middle cerebral artery. This may be one of the molecular mechanisms by which electroacupuncture at the Shuohui point improves nerve functioning in treating cerebral infarction.

Objective To analyze the causal relationship between immune cell phenotype and gastric cancer. Methods Bidirectional two-sample Mendelian randomization (MR) analysis was used to select 731 genetic variants involving immune cell phenotypes from the GWAS dataset as instrumental variables. Inverse-variance weighting method (IVW), weighted median method (WM), and MR-Egger regression were used for sensitivity analysis. Cochran Q test, MR-Egger regression, MR-PRESSO method, and remain-one method were also conducted. Results Changes in the absolute count of IgD+ B cells and CD14-CD16- cells were significantly associated with the risk of gastric cancer. A lower proportion of IgD+ B cells was associated with a lower risk of gastric cancer (OR=0.86, 95%CI: 0.79-0.94), while an increased number of CD4-CD8-T cells was associated with an increased risk of gastric cancer (OR=1.2, 95%CI: 1.1-1.3). Conclusion A causal relationship exists between immune cell phenotype and the risk of gastric cancer. Changes in specific immune markers may regulate the development of gastric cancer by affecting the tumor microenvironment.

Objective:To analyze the changing trend of cervical cancer epidemiological characteristics and disease burden in cancer registration areas of Guangxi Zhuang Autonomous Region (Guangxi) from 2010 to 2017, and to provide scientific basis for the development of cervical cancer prevention and control strategies in Guangxi.Methods:Using descriptive analysis method, based on the incidence and death data of cervical cancer in the tumor registration areas of Guangxi from 2010 to 2017, Crude morbidity, crude mortality, age-standardized morbidity and mortality (referred to as the winning rate), disability adjusted life years (DALYs) rate and the annual percentage change (APC) and average annual percentage change (AAPC) of the above indicators were calculated, and stratified analysis was conducted for urban and rural areas and different age groups.Results:From 2010 to 2017, the crude incidence rate of cervical cancer in Guangxi showed a significant upward trend, rising from 10.31/10 5 in 2010 to 19.94/10 5 in 2017, with an average annual growth rate of 7.9% ( P＜0.05). However, after age standardization, the trend of the age-standardized incidence rate of cervical cancer was not statistically significant ( P＞0.05). During the same period, the crude mortality rate of cervical cancer increased from 2.69/10 5 to 6.21/10 5, with an average annual growth rate of 13.1% ( P＜0.05), and the trend of the age-standardized mortality rate was basically consistent with that of the crude mortality rate. The analysis of urban-rural differences showed that the growth rates of the crude incidence rate and crude mortality rate of cervical cancer in rural areas were higher than those in urban areas from 2010 to 2017 (AAPC incidence rate: 21.3% vs. 2.3%; AAPC mortality rate: 20.1% vs. 8.4%). The analysis of age differences showed that the crude incidence rate and crude mortality rate of cervical cancer in all age groups increased to varying degrees, among which the growth rate of the incidence rate (AAPC=16.2%, P＜0.05) and mortality rate (AAPC=14.7%, P＜0.05) of cervical cancer in women aged 65 and above was the fastest. In addition, the DALYs rate of cervical cancer in Guangxi increased from 50.6/10 5 in 2010 to 111.0/10 5 in 2017, with an average annual increase of 11.9% ( P＜0.05). The growth rate of the DALYs rate in rural areas was higher than that in urban areas, and the growth rate of the DALYs rate in the 50-59 age group was higher than those in other age groups. Conclusions:From 2010 to 2017, the incidence rate, mortality rate and DALYs rate of cervical cancer in Guangxi showed an upward trend. Comprehensive prevention and control measures for cervical cancer, such as improving the early diagnosis and treatment system, promoting the popularization of HPV vaccination and strengthening health education, should be taken to reduce the disease burden of cervical cancer.
