BACKGROUND: Lung cancer is a disease with a high incidence rate in Yunnan province, yet there is a paucity of large-scale studies on its clinical epidemiology. This research aims to investigate the epidemiological characteristics of patients who underwent lung cancer surgery at Yunnan Cancer Hospital over the past decade, thereby providing a theoretical basis for the prevention and treatment of lung cancer. METHODS: Clinical data were collected from 15,967 patients who underwent lung cancer surgery at Yunnan Cancer Hospital between 2013 and 2022. A statistical analysis was conducted on the patients' general data, surgical information, pathological types of lung cancer, and other clinical epidemiological characteristics. RESULTS: Among the 15,967 cases of lung cancer, 46.3% were male and 53.7% were female, with the male-to-female ratio ranging from 0.68 to 1.61:1. The median age was 56 years (interquartile range: 49-63), and 37.0% of the patients were in the age group of 50-59 years. Since 2017, there has been an annual increase in the proportion of patients under the age of 60 years. The smoking status of the patients showed that 28.1% were smokers and 71.9% were non-smokers. Qujing city accounted for 41.4% and Kunming city for 23.2% of the cases in Yunnan province, with 29.6% of patients originating from Xuanwei and Fuyuan areas of Qujing city. The distribution of affected lung lobes was as follows: right upper lobe 28.2%, right middle lobe 6.3%, right lower lobe 20.1%, left upper lobe 22.7%, and left lower lobe 16.4%. The use of thoracoscopic surgery increased from 30.8% to 96.3%, with single-port thoracoscopic surgery comprising 61.3%. Lobectomy was performed in 64.2% of cases, wedge resection in 17.2%, and segmentectomy in 12.2%. The proportion of lobectomy decreased from 83.1% to 46.1%. The proportion of patients in stages 0-I increased from 43.5% to 82.8%, while stages II-IV decreased from 56.5% to 17.2%. Adenocarcinoma increased from 75.6% to 88.3%, and squamous cell carcinoma decreased from 21.5% to 8.6%. Among adenocarcinoma patients, 60.9% were female. Among sguamous cell carcinoma patients, 90.6% were male. The peak age for adenocarcinoma was 50-59 years, and for squamous cell carcinoma, it was 60-69 years. The smoking rate was higher among squamous cell carcinoma patients (65.9%) compared to adenocarcinoma patients (22.3%). Adenocarcinoma patients had a higher proportion in stages 0-I (76.3%), while squamous cell carcinoma patients were more prevalent in stages II-III (64.1%). CONCLUSIONS The findings indicate an increasing proportion of female patients with adenocarcinoma, a younger age of onset, a higher proportion of non-smoking lung cancer patients, and an increased proportion of stages 0-I lung cancer. These trends may reflect the epidemiological characteristics of patients undergoing lung cancer surgery in Yunnan and surrounding areas over the past decade.

Lung cancer is the leading cause of cancer death in the world today, and adenocarcinoma is the most common histopathological type of lung cancer. In May 2021, World Health Organization (WHO) released the 5th edition of the WHO classification of thoracic tumors, which classifies invasive non-mucinous adenocarcinoma (INMA) into lepidic adenocarcinoma, acinar adenocarcinoma, papillary adenocarcinoma, solid adenocarcinoma, and micropapillary adenocarcinoma based on its histological characteristics. These five pathological subtypes differ in clinical features, treatment and prognosis. A complete understanding of the characteristics of these subtypes is essential for the clinical diagnosis, treatment options, and prognosis predictions of patients with lung adenocarcinoma, including recurrence and progression. This article will review the grading system, morphology, imaging prediction, lymph node metastasis, surgery, chemotherapy, targeted therapy and immunotherapy of different pathological subtypes of INMA.

Candida albicans is the most prevalent fungal species of the human microbiota.Many nosocomial Candida albicans infections are polymicrobial.The interaction between Candida albicans and other bacteria can be synergistic,antagonistic,and one side benefit,which cause damage of host in different way.Co-infections influence the biochemistry and polybiofilm among pathogenic microorganisms,and then change the drug resistance,response host immunity,and virulence.This makes co-infections more difficult to be cured than mono-infections.The coinfection of Candida albicans and other bacteria has a high incidence rate and mortality rate,which is a serious problem faced by clinicians.The mechanism of interaction between Candida albicans and other bacteria has an important significance in diagnosis and co-infection treatment.In this paper,the research progress of interaction between Candida albicans and Staphylococcus aureus,Pseudomonas aeruginosa,Streptococcus mutans,as well as Lactobacilli was reviewed.

We have established a digital coronary angiograph-analyzing system on the principle of coronary angiographic impulse response, and combined the system with the quantitative coronary analysis (QCA) for investigating the coronary microcirculation (Tmicro(-1)), the minimal stenotic diameter of coronary (MLD) and coronary hemodynamic parameters (mAP, CFV, Rcor) in 20 patients with coronary stenosis. The results showed the minimal stenotic diameter (MLD) and Tmicro(-1) decreased, with the increase of stenosis of proximal coronary. After successful percutaneous coronary intervention treatment, the Tmicro(-1) increased with the increase of MLD and was in linear correlation with MLD (r = 0.87, P < 0.001). In conclusion, The index Tmicro(-1) detected by coronary digital angiographic impulse response analysis system in combination with CFV and QCA would help to evaluate the level of integrated diagnosis of coronary lesion in regard to anatomy and physiology as well as to macro and microcirculation.

Based on a secret prescription(Dongyuan Jiajiu),Compound Sea-horse Medicinal Liquor (CSM^) is prepared with spirit contained lower percent alcohol as carrier. The main components of CSML include sea-horse (Hippocampus) ,pipe-fish (Syngnathus) .sea-snake, the external genetals of the stag and the sea-snake,etc. With rich amino acids and trace elements,CSML can produce specific biological effects in the human body,such as syn-thesing ATP, promoting the secretion of endogenous androgens. The pharmacological and toxicological studies have shown that CSML can strengthen immune fumction,increase the body' s anti-fatigue action without any toxicity. Clinical observations have indicated that CSML can help reinforcing essence of the kidney and invigorating vital function .stimulating the blood circulation to relax muscles and tendons,as well as replenishing and reinforcing vital energy. As a pure natural and safe athletic tonic with ideal efficacy of increasing sport endurance,CSML srould be recommended.
