With the accelerating trend of population aging, the number of elderly patients with lung cancer continues to rise, and the disease burden is becoming increasingly heavy. The clinical management of these patients faces severe challenges due to their decreased physiological reserve, complex comorbidities, and significant individual heterogeneity. Consequently, under traditional diagnosis and treatment models, doctors often struggle to identify the individualized risks of elderly patients in a timely and comprehensive manner, which can easily lead to decision biases such as undertreatment or overtreatment. In view of this, this study advocates for the establishment of an umbrella decision-making model specifically tailored for elderly lung cancer patients. Grounded in a multidisciplinary team (MDT) platform, this model deeply integrates oncological indicators with the comprehensive geriatric assessment (CGA) system. By holistically considering multidimensional variables including tumor burden, organ function, frailty index, cognitive status, and social support, the model establishes an operational mechanism characterized by "single entry, precise stratification, and targeted selection". Accordingly, patients can be scientifically triaged into distinct intervention tiers, such as active surveillance, minimally invasive surgery, drug therapy, radiotherapy, and best supportive care, thereby achieving real-time alignment between treatment intensity and patient fitness. This article elaborates on the construction logic and key operational procedures of this novel decision-making framework, aiming to guide clinical practice beyond the limitations of a tumor-centric perspective toward a holistic, dynamic, whole-course management strategy. This transition seeks to ensure optimal quality of life and clinical net benefit for elderly patients alongside survival prolongation.

Myostatin gene (MSTN) encodes a negative regulator for controlling skeletal muscle growth in animals. In this study, MSTN^-/- homozygous mutants with "double muscle" phenotypic traits and stable inheritance were bred on the basis of MSTN gene editing rabbits, with the aim to establish a method for breeding homozygous progeny from primary MSTN biallelic mutant rabbits. MSTN^-/- primary mutant rabbits were generated by CRISPR/Cas9 gene editing technology. The primary mutant rabbits were mated with wild type rabbits to produce F1 rabbits, whereas the F2 generation homozygous rabbits were bred by half-sibling mating or backcrossing with F1 generation rabbits of the same mutant strain. Sequence analysis of PCR products and its T vector cloning were used to screen homozygous rabbits. The MSTN mutant rabbits with 14-19 week-old were weighed and the difference of gluteus maximus tissue sections and muscle fiber cross-sectional area were calculated and analyzed. Five primary rabbits with MSTN gene mutation were obtained, among which three were used for homozygous breeding. A total of 15 homozygous rabbits (5 types of mutants) were obtained (M2-a: 3; M2-b: 2; M3-a: 2; M7-a: 6; M7-b: 2). The body weight of MSTN^-/- homozygous mutant rabbits aged 14-19 weeks were significantly higher than that of MSTN^+/+ wild-type rabbits of the same age ((2 718±120) g vs. (1 969±53) g, P < 0.01, a 38.0% increase). The mean cross sections of gluteus maximus muscle fiber in homozygous mutant rabbits were not only significantly higher than that of wild type rabbits ((3 512.2±439.2) μm² vs. (1 274.8±327.3) μm², P < 0.01), but also significantly higher than that of MSTN^+/- hemizygous rabbits ((3 512.2±439.2) μm² vs. (2 610.4±604.4) μm², P < 0.05). In summary, five homozygous mutants rabbits of MSTN^-/- gene were successfully bred, which showed a clear lean phenotype. The results showed that the primary breeds were non-chimeric mutant rabbits, and the mutant traits could be inherited from the offspring. MSTN^-/- homozygous mutant rabbits of F2 generation could be obtained from F1 hemizygous rabbits by inbreeding or backcrossing. The progenies of the primary biallelic mutant rabbits were separated into two single-allelic mutants, both of which showed a "double-muscle" phenotype. Thus, this study has made progress in breeding high-quality livestock breeds with gene editing technology.

Objective:To investigate the efficacy and safety of ticagrelor and clopidogrel in patients with coronary atherosclerotic heart disease (CHD) and hyperhomocysteinemia (Hhcy).Methods:A total of 101 patients with CHD complicated with HHcy who had successfully undergone percutaneous coronary intervention (PCI) were enrolled. They were divided into ticagrelor group ( n=49) and clopidogrel group ( n=52) according to the different antiplatelet drugs used. The clinical data of the two groups were collected, and the incidence of major cardiovascular and cerebrovascular adverse events (MACCE) and bleeding events in one year were compared between the two groups. Results:There was no statistical difference in baseline datas and PCI datas between the clopidogrel and ticagrelor groups ( P>0.05). Compared with clopidogrel group, ticagrelor can reduce the total MACCE (8.16% vs 32.69%, P<0.05) and the incidence of unstable angina pectoris events (0 vs 13.46%, P<0.05) in patients with hyperhomocysteinemia PCI 1 year after operation. The incidences of ischemic stroke, unstable angina pectoris, recurrent myocardial infarction, and cardiogenic death were compared separately between the two groups, and the difference was not statistically significant ( P>0.05). The incidence of major bleeding events, minor bleeding events, and minimal bleeding events were similar between the two groups, and the difference was not statistically significant (4.08% vs 0; 4.08% vs 1.92%; 20.41% vs 9.62%; P>0.05). Conclusions:In patients with CHD and Hhcy, ticagrelor can play a better antithrombotic effect, reduce the incidence of ischemic events, and has good security, which is more worthy of clinical recommendation.

Objective:To compare the clinical and prognostic characteristics of ovarian endometrioid carcinoma (OEC) patients with synchronous endometrial lesions and patients with pure OEC.Methods:A retrospective review of the medical records of patients received initial treatment and a postoperative pathological diagnosis of OEC at Peking University People′s Hospital between August 1998 and December 2017 were performed. According to the inclusion criteria, a total of 56 patients with OEC were included in the study, including 13 patients concurrent with simultaneous endometrial lesions (Group A) and 43 patients with pure OEC (Group B).Results:Patients with synchronous endometrial lesions accounted for 23% (13/56). Mean age of Group A at diagnosis was (44.9±8.3) years old, 2/13 of patients were postmenopausal, and no one had a history of hypertension, the first symptom of 5/13 people was irregular vaginal bleeding. Mean age of Group B patients at diagnosis was (52.7±10.2) years old, 53% (23/43) of patients were postmenopausal, and 28% (12/43) patients had the history of hypertension, the first symptom of 4 (9%, 4/43) people was irregular vaginal bleeding. The differences of age, menopause status, history of hypertension and initial symptoms between the two groups were statistically significant (all P<0.05). There were no significant differences in fertility history, dysmenorrhea history, age of menarche, history of endometriosis, preoperative and postoperative CA 125 level, International Federation of Gynecology and Obstetrics (FIGO) stage, tumor grade, metastatic site and platinum-based chemotherapy drug resistance between the two groups (all P>0.05). The overall 5-year survival rate of OEC patients was 91.6%, and the overall 5-year progression-free survival rate was 76.6%. Among them, the 5-year survival rate of the OEC concurrent with simultaneous endometrial lesions group was 80.2%, and the pure OEC group was 93.4%; the 5-year progression-free survival rate of the OEC concurrent with simultaneous endometrial lesions group was 74.1%, and the 5-year progression-free survival rate of the pure OEC group was 77.3%. There were no significant differences between the two groups (all P>0.05). Multivariate analysis showed that the independent factors for the prognosis of OEC patients were FIGO stage ( P=0.006) and residual lesion size ( P=0.020). Conclusions:OEC patients have a high proportion of simultaneous endometrial lesions. OEC with simultaneous endometrial lesions are younger than patients with pure OEC. Synchronous endometrial lesions do not affect the prognosis of patients with OEC.

Objective:To evaluate the efficacy and safety of endoscopic trans-gastric gallbladder-preserving polypectomy in treatment of gallbladder polyps.Methods:A retrospective analysis was performed on data of 25 patients with gallbladder polyps who underwent endoscopic trans-gastric gallbladder-preserving polypectomy in the endoscopy center of Zhongshan Hospital from September 2017 to August 2019. Completion of operation, operation time, postoperative hospital stay, complications and follow-up results of patients were obtained and analyzed.Results:There were 13 cases of single polyp and 12 cases of multiple polyps, 13 cases of simple gallbladder polyps, and 12 cases of polyps and gallstones. The maximum diameter of polyps was 0.2-1.5 cm. The procedure failed in 1 patient (4%) because of the severe adhesion of abdominal cavity and disappearance of gallbladder when passing through the gastric wall. Twenty-four patients (96%) were successfully treated with endoscopic trans-gastric gallbladder-preserving polypectomy. The operation time was 67.1±26.8 min (35-140 min). The median hospital stay was 4 d (2-5 d). No severe adverse events including delayed bleeding, delayed perforation, diffuse peritonitis or abdominal abscess occurred. During the median follow-up time of 8 months (0-23 months), no patient was lost, no recurrence of polyps and no severe adverse events related to metal clips occurred.Conclusion:Endoscopic trans-gastric gallbladder-preserving polypectomy shows good short-term efficacy and is technically feasible, however, long-term outcome still requires further research.
