BACKGROUND: Perioperative treatment has become an increasingly important aspect of the management of patients with non-small cell lung cancer (NSCLC). Small-scale clinical studies performed in recent years have shown improvements in the major pathological remission rate after neoadjuvant therapy, suggesting that it will soon become an important part of NSCLC treatment. Nevertheless, neoadjuvant immunotherapy may be accompanied by serious adverse reactions that lead to delay or cancelation of surgery, additional illness, and even death, and have therefore attracted much attention. The purpose of the clinical recommendations is to form a diagnosis and treatment plan suitable for the current domestic medical situation for the immune-related adverse event (irAE). METHODS: This recommendation is composed of experts in thoracic surgery, oncologists, thoracic medicine and irAE related departments (gastroenterology, respirology, cardiology, infectious medicine, hematology, endocrinology, rheumatology, neurology, dermatology, emergency section) to jointly complete the formulation. Experts make full reference to the irAE guidelines, large-scale clinical research data published by thoracic surgery, and the clinical experience of domestic doctors and publicly published cases, and repeated discussions in multiple disciplines to form this recommendation for perioperative irAE. RESULTS: This clinical recommendation covers the whole process of prevention, evaluation, examination, treatment and monitoring related to irAE, so as to guide the clinical work comprehensively and effectively. CONCLUSIONS Perioperative irAE management is an important part of immune perioperative treatment of lung cancer. With the continuous development of immune perioperative treatment, more research is needed in the future to optimize the diagnosis and treatment of perioperative irAE.

The clinical application of immune checkpoint inhibitors (ICIs) has significantly improved the prognosis of hepatocellular carcinoma (HCC) patients. With the widespread applica-tion of ICIs in HCC, the management of immune-related adverse events (irAE) gained more and more attention. However, the complicated disease characteristics and various combination therapies in HCC throw out challenges to irAE management. Therefore, the editorial board of the 'Chinese expert consensus on the management of immune-related adverse events of hepatocellular carcinoma treated with immune checkpoint inhibitors (2021 edition)' organizes multidisciplinary experts to discuss and formulate this consensus. The consensus focuses on issues related to HCC irAE manage-ment, and puts forward suggestions, in order to improve standardized and safety clinical medication, so as to maximize the benefits of immunotherapy for patients.

Asthma is a chronic airway inflammatory disease, and airway remodeling is one of its typical pathological features.Airway remodeling can result in hyperactivity, irreversible airflow limitation, and even decreased lung function.Studies have shown that the Wnt/β-catenin signaling pathway plays an important role in post-injury repair of the lung.Abnormal activation of the Wnt/β-catenin signaling pathway leads to airway remodeling in asthma.This article will review the progress of Wnt/β-catenin signaling pathway and asthma-related airway remodeling, and explore its possible therapeutic targets in asthma.

Objective To investigate the application value of mini-nutritional assessment short-form(MNA-SF) in screening and evaluating nutritional status in elderly hospitalized patients with malignant tumor.Methods 1472 elderly hospitalized patients(≥65 years old)with malignant tumor were enrolled and prospectively studied for evaluating the nutritional status by nutritional risk screening 2002 (NRS 2002)assessment.Indicators of clinical outcomes were summarized.The consistencies of MNA-SF with body mass index(BMI),grip and results of NRS 2002 assessment,and the relationship between the different nutritional status and clinical outcomes were analyzed.Results The patients meeting the inclusion/exclusion criteria were aged(72.1±5.9)years,with BMI of(22.3 ±3.7)kg/m2 and grip of(21.7± 19.0)kg.Among 16.7％ of the malnourished patients with malignant tumors,pancreatic cancer (30.9 ％),bile duct cancer (24.1％) and esophageal cancer (21.2 ％) occupied the top three incidence of malnutrition,with the lowest (5.4％)incidence in breast cancer.Among 59.2％ of patients being malnourished (16.7％)or at risk(42.5％)of malnutrition,the highest incidence was in bile duct cancer(82.8％),and lowest one was in breast cancer(28.6 ％).MNA-SF-discriminated malnutrition(0～ 7 points)showed a great agreement with malnutrition evaluation by BMI(＜18.5),but had a poor agreement with grip in screening malnutrition.MNA-SF-discriminated nutrition problem(malnourishment plus at risk of malnutrition)showed a great agreement with NRS 2002-discovered nutrition problem (score≥3).Under-nourished patients had a higher infection complication(9.29％ vs.5.14％,P =0.006)and longer hospital stays(15.4 d vs.12.8 d,P＜0.01)as compared with patients with normal nutrition status.Conclusions The prevalence and risk factors for malnutrition are higher in elderly patients with malignant tumor.Poor nutritional status is correlated with poor clinical outcomes.MNA-SF can be used as a tool for evaluating the nutritional status of elderly patients with malignant tumor.

Objective:To investigate the clinical efficacy and immunological mechanism of herbal cake-partitioned moxibustion for aging process.Method:The herbal cake-partitioned moxibustion was adopted for 223 cases to observe the aging scores before and after the treatment.Apart from that,the T-lymphocyte subsets and changes of IL-2 and 3-EP were also detected.Results:After treatment,the aging scores of 223 cases were all substantially reduced,along with an improvement of clinical symptoms,a strengthened cellular immune function,and an increase of total T-lymphocyte count.In addition,the CD4+/CD8+ ratio Was restored normal,the synthesis or secretion of IL-2 was increased and the β-EP(as the neurotransmitter to modulate immune function)was substantially improved.Conclusion:The aging process is closely associated with the immune function.Moxibustion Can modulate abnormal immune function and stabilize homeostasis and thus delay the aging process.

Objective To evaluate the feasibility and safety of vaginal enlarged amputation of cervix to treat patients with cervical cancer of stage Ⅰ a1 and cervical intraepithelial neoplasia grade Ⅲ(CIN Ⅲ)who were unfit for conization surgery.Methods From July 2002 to May 2007,patients with cervical cancer at stage Ⅰ a1,diagnosed by pathology after loop electrosurgical excision procedure(LEEP),large area CIN Ⅲ(the area of lesion≥3/4 on colposcopy),CIN Ⅲ coexisted with vaginal intraepithelial neoplasia (VAIN)in the superior segment of vagina,CIN Ⅱ-Ⅲ recurrence or with residual lesion,positive margin after conization of cervix,who wanted to preserve fertility and(or)corpus uteri were selected to receive vaginal enlarged amputation of cervix.Results Forty-eight eases including 5 with cervical cancer in stage Ⅰ a1,38 with large area CIN Ⅲ(9 with gland involvement),2 with residual lesion and 2 with positive margin after LEEP,1 recurrence after cold knife conization,received the procedure successfully.The median age was 34 years(range 27-40),median operation time was 60 minutes(range 30-100),median blood loss was 40 ml(range 5-300),and median hospital stay was 10 days(range 7-17).After follow-up 1-39 months,no patient had postoperative complications and recurrence,and all patients resumed normal menstrual cycle and sexual life.Condusion Vaginal enlarged amputation of cervix appears to be a safe and feasible procedure for patients with cervical cancer at stage Ⅰ a1 and CIN Ⅲ who are unfit for conization surgery.

Objective: To investigate the effect of moxibustion on telomerase activity and genes expression in tissues of senescent rats. Methods: Subacute aging rats model were established by injection with D-gal solution. Points Shenshu (BL 23) were treated with moxibustion in treatment group, contrasting with a model group and a normal group. Enzyme-Linked Immunosorbent Assays(ELISA) was used for the level oftelomerase activity in liver tissues, and In Situ Hybridization(ISH) was used for the condition of expression of telomerase genes in liver tissues. Results: The level of telomerase activity in the aging model group was obviously lower than that in normal control group (P＜0.01), the level in moxibustion group was obviously higher than that in model group(P＜0.05). In comparison with normal rats, the positive-expressed areas and photodensity of telomerase genes in aging model group were all significantly lower (P＜0.01,P＜0.01), and the positive-expressed areas in moxibustion group was significantly higher than that in model group (P＜0.01). Conclusions: Moxibustion could regulate telomerase activity of senile rats, hence delaying aging.

Objective To identify and quantitate the conjunctival aerobic bacterial flora from healthy people of 3 age groups in Chongqing city.Methods Samples taken with moist swabs from the lower fornix of both eyes of 33 children(9.85?0.57 years old),31 youths(21.23?0.88 years old)and 30 elders(72.97?4.94 years old)were given bacterial cultures.Positive ones were identified and colony forming units(CFUs)were counted.Bacterial quantity was expressed as the number of CFUs divided by the weight of each sample measured before and after collection.Results The elders showed a higher isolation frequency(93.33%)than children(45.45%)and youths(50.00%)which had statistically difference(P

Objective To observe the therapeutic effects and action mechanism of moxibustion in the treatment of intestinal fibrosis in ulcerative colitis. Methods Tianshu (ST 25) and Qihai ( CV 6) were the main acupoint; other points were used according to syndrome differentiation. Sixty-five patients were randomized into two groups: Group A in which 32 cases were treated by herbpartitioned moxibustion and group B in which 33 cases were treated by bran-partitioned moxibustion. The therapeutic effects and TGF-β1, Ⅰ and Ⅲ collagen expressions were measured before and after treatment. Results In group A, 17 cases were cured, 12 cases improved and 3 failed; in group B, 1 1 cases were cured, 16 cases improved and 6 cases failed. Ⅰ , Ⅲ collagen expressions were obviously inhibited in the two groups, in group A in particular. Conclusion In the prevention and treatment of intestinal fibrosis, moxibustion may reduce the expression of TGF-β1, and hence to block or inhibit the synthesis of Ⅰ、Ⅲ collagens, and improve the structure and function.
