The theoretical basis of premature aging originates from The Yellow Emperor's Inner Classic. The etiology of premature aging is complex， and the disease mechanism is based on deficiency. The treatment for premature aging is based on tonicity. The essence-Qi-spirit theory of Qiluo doctrine summarizes that "essence is the origin of life， Qi is the driving force of life， and spirit is the embodiment of life"， which is the law of life. The theory puts forward the core disease mechanism of aging， which states that "deficiency of kidney essence is the root of aging， deficiency of primordial Qi is the key to aging， impairment of soma and spirit is the manifestation of aging". The theory also proposes the treatment of "tonifying kidney and supplementing essence， harmonizing Yin and Yang， warming and supporting primordial Qi， and nourishing soma and spirit" and the representative anti-aging drugs. The article unfolds from the perspective of the concepts of natural life span， premature senility before fifty， decline， and aging and also explains the origins and connotations of premature aging. The article explains the disease mechanism of premature aging under the guidance of the essence-Qi-spirit theory of Qiluo doctrine， which is "early deprivation of kidney essence， deficiency of primordial Qi， accumulation of deficiencies into impairment， and decline and impairment of soma and spirit"， summarizes the progress of modern medical research on the treatment of premature aging and representative drugs， and finds that Bazi Bushen capsules have a precise therapeutic effect on the overall premature aging， systematic functional decline， and related diseases. The study provides theoretical basis and new ideas to solve the problems of premature aging and geriatric diseases.

ObjectiveBased on modern analytical techniques and a depressed mouse model established by chronic unpredictable mild stress（CUMS）， to evaluate the quality marker（Q-Marker） and pharmacodynamic difference of Baihe Dihuangtang prepared by different processes. MethodsHigh performance liquid chromatography（HPLC） was used to establish the characteristic profiles of Baihe Dihuangtang， and determine the content of Q-Marker in the samples prepared by ancient and modern processes. Seventy C57BL/6J mice were randomly divided into the normal group， model group， fluoxetine group（3 mg·kg^-1）， low and high dose groups of ancient process（6.5， 26 g·kg^-1）， and low and high dose groups of modern process（6.5， 26 g·kg^-1）， with 10 mice in each group. Except for the normal group， CUMS was used to induce depression in mice from the other groups for 28 d. After successful modeling， administration groups were given the corresponding drugs by gavage every day， and the normal and model groups were given an equal volume of pure water by gavage for 21 consecutive days. Change in body mass of mice was recorded， tail suspension test and open field test were used to evaluate the depressive behavior of mice， and enzyme-linked immunosorbent assay（ELISA） was employed to determine the contents of tumor necrosis factor-α（TNF-α）， interleukin（IL）-1β and IL-6 in serum. ResultsCharacteristic profiles of Baihe Dihuangtang prepared by the two processes were established， the similarity between the two was 0.951， and 8 characteristic peaks were recognized with the reference peak of regaloside A. The results of quantitative analysis showed that the Q-Marker content was similar in Baihe Dihuangtang prepared by ancient and modern processes. The results of pharmacodynamics showed that， compared with the normal group， the model group showed increased immobility time in the tail suspension test， reduced total movement distance in the open field test， and elevated IL-1β， IL-6 and TNF-α levels in the serum（P<0.01）. Compared with the model group， the behavioral indicators of mice in the Baihe Dihuangtang treatment group were significantly improved in terms of tail suspension time and open field exercise， and the levels of IL-1β， IL-6 and TNF-α in serum were significantly reduced（P<0.05， P<0.01）. Baihe Dihuangtang prepared by the two processes both had antidepressant effects， and the difference between the two was not statistically significant in improving depressive symptoms. ConclusionQ-Marker of Baihe Dihuangtang prepared by modern and ancient methods are equivalent in content， and the pharmacological effects are consistent， indicating that dried Lilii Bulbus can replace fresh products in the preparation of Baihe Dihuangtang. This study provides a scientific basis for the development of new drugs of Baihe Dihuangtang and a reference for its rational application and clinical use.

OBJECTIVES: To analyze the differences in the prognosis of gastric signet ring cell carcinoma (SRCC) among different races using the US Surveillance Epidemiology and End Results (SEER) database and The Cancer Genome Atlas (TCGA) database. METHODS: We analyzed the data of patients with gastric SRCC from the SEER database from 2000 to 2020, and divided the patients into cohorts of whites, blacks, Asians or Pacific Islanders, American Indians/Alaska Natives according to their race. The prognosis and treatment of the cohorts were evaluated using baseline demographic analysis, Kamplan-Meier survival curve, and nomogram analysis. RESULTS: We analyzed the data of a total of 2058 patients, including 8.6% blacks, 72.4% whites, 16.6% Asians or Pacific Islanders, 1.0% American Indians/Alaska Natives, and 1.4% other races. The tumor grade varied among different races, and the prevalence and survival rates of patients differed significantly across races. The differences in the white cohort were the most prominent, and all the differences were statistically significant (P<0.05). Racial differences were also noted in patient management and prognosis. CONCLUSIONS There are racial differences in tumor grades and prognosis of gastric SRCC, and these differences provide evidence for optimizing clinical diagnosis and treatment strategies for this malignancy.

Baihe Dihuangtang is a famous classical formula that has been respected by physicians in the past and is still used today. It was first recorded in ZHANG Zhongjing's Synopsis of the Golden Chamber， and is composed of Lilii Bulbus and Rehmanniae Radix juice. This paper systematically reviewed the research progress of historical evolution， pharmacological activities and clinical applications of Baihe Dihuangtang in recent years， and found that there was no major changes in the composition， decoction method and indications of this formula since the Han dynasty. According to the herbal textual research， the fleshy scaly leaves of Lilium brownii var. viridulum should be selected for Lilii Bulbus in this formula， and the tuberous roots of Rehmannia glutinosa were selected for Rehmanniae Radix. According to the dosage conversion of ancient and modern times， the dosage is 245 g of fresh Lilii Bulbus and 400 g of fresh Rehmanniae Radix， and the ratio of their juice is 1∶1. Its efficacy is to nourish Yin and clear heat， and to tonify the heart and lungs， which is used to treat the heart and lung Yin deficiency syndrome of lily disease. Modern pharmacological studies have shown that the research on the pharmacological effects of Baihe Dihuangtang mainly focuses on anti-depressant， anti-anxiety， improving insomnia and regulating metabolism， and it is mostly used clinically for neurological disorders such as depression， anxiety and insomnia. The quality marker（Q-Marker） of Baihe Dihuangtang were predicted according to the principles of ingredient specificity， component validity， component measurability， formula compatibility， and quality transmissibility and traceability， and it was determined that catalpol， rhmannioside D， regaloside A， regaloside B， regaloside C， and acteoside could be selected as potential Q-Markers of Baihe Dihuangtang， which could provide scientific reference for the establishment of the quality control system and the development of compound preparation of this famous classical formula.

AIM:To observe the effect of fudostei-ne on induced sputum cell components and lung function in patients with stable neutrophil-dominat-ed COPD.METHODS:From October 2019 to Octo-ber 2022,53 patients with stable COPD were select-ed and divided into fudosteine group and placebo group.The placebo group was treated with routine treatment,and the fudosteine group was treated with fudosteine on the basis of routine treatment.The two groups were treated for 6 months.The clinical symptoms[Saint George's Respiratory Questionnaire(SGRQ),COPD Assessment Test(CAT)and Modified British Medical Research Council Dys-pnea scale(MMRC),Breathlessness,Cough,and Sputum Scale(BCSS)],lung function index,induced sputum cytology analysis and other related exami-nation results were recorded in detail before and after treatment.RESULTS:(1)Compared with the baseline,the forced expiratory volume in one sec-ond(FEV1),forced vital capacity(FVC),and the ra-tio of FEV1 to FVC(FEV1/FVC)of the two groups were improved after treatment,and the differenc-es were statistically significant(P＜0.05).However,after treatment,there was no significant difference in pulmonary function between the two groups ex-cept for the percentage of carbon monoxide diffu-sion in the predicted value(DLCO％pre)(DLCO％pre in the fudosteine group was higher than that in the placebo group).(2)After treatment,the total num-ber of induced sputum cells and neutrophil counts in the fudosteine group were lower than those in the placebo group.Compared with the number of cells in each component at baseline,the total num-ber of induced sputum cells and neutrophil count in the fudosteine group were significantly lower(P＜0.05).CONCLUSION:Fudosteine treatment in pa-tients with stable neutrophil-dominated COPD can improve lung function,reduce the total number of induced sputum cells and the total number of neu-trophils,thereby improving airway inflammation.
