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.

OBJECTIVE To explore the clinical characteristics of Tropheryma whipplei(TW)infection and observe the application of pathogenic metagenomic next-generation sequencing(mNGS)in diagnosis of TW infection.METHODS The clinical data were collected from 1 patient who was diagnosed by mNGS in the Affiliated Hospital of Jining Medical University on Apr.9,2022.The data including the results of laboratory tests and treatment out-comes were summarized,and a literature review was conducted.RESULTS A 50-year-old woman presented to the hospital with chest tightness and chest pain lasting for 3 days,accompanied by dyspnea,palpitations,and expec-toration.The chest plain CT scan and magnetic resonance imaging(MRI)scan suggested a high probability of pul-monary infection.Normal flora were isolated by culture of bronchoalveolar lavage fluid(BALF);TW and human βherpes virus type 7 were detected in BALF by mNGS,with the sequence numbers 327 000 and 9,respectively.The pulmonary symptoms of the patient were improved after joint treatment of the infection with etimicin,levo-floxacin and minocycline.The patient repeatedly sought for medical treatment due to the pain of shoulder joint and limitation of motion.CONCLUSIONS TW is one of major pathogens leading to the infections of systemic multiple systems,and it is necessary to attach great importance to the diagnosis and treatment.The traditional laboratory test method can not achieve ideal diagnosis effect and is more likely to make a missed diagnosis.mNGS is more ac-curate and more efficient than the traditional detection method in diagnosis of TW-induced diseases.Early use of mNGS can make a rapid identification of pathogens and facilitate the reasonable clinical use of antibiotics.It is of great significance for control of the disease progression,improvement of prognosis and prevention of recurrence.

Background: This study was performed to investigate the imaging features of mDIXON-Quant sequence (Philips Healthcare) and proton magnetic resonance spectroscopy (1H-MRS) of thigh muscles in patients with stroke-related sarcopenia (SRS). Methods: This prospective case-control study was conducted in 40 patients with SRS, 40 patients without sarcopenia who had a stroke, and 40 healthy volunteers using mDIXON-Quant and 1H-MRS scanning. Skeletal muscle cross-sectional area (CSA) and fat fraction (FF) were analyzed. Results: The skeletal muscle FF value was significantly higher (p<0.05) in patients with SRS and on the affected side. The extracellular fat content of the rectus femoris muscle in normal controls was 4× to 10× the intracellular fat content. A significant increase (p<0.05) in intra- and extracellular fat content was detected in the SRS group. The degree of fat content increase in the SRS group was significantly lower (p<0.05) for extracellular fat than intracellular fat, with a ratio of extracellular to intracellular fat content of <4. The intracellular fat content was significantly higher (p<0.05) in the SRS group. A moderate-to-strong positive correlation existed between intracellular fat content (area 1) and muscle fat percentage. The degree of decrease in CSA in the posterior muscle group was significantly greater (p<0.05). Conclusion Thigh muscle CSA significantly decreased in SRS, while FF increased. The intra- and extracellular fat content of the skeletal muscle was significantly increased, especially the intracellular fat content. SRS was confirmed when the ratio of extracellular fat content to intracellular fat content was <4.

To summarize the nursing care of a very low birth weight premature infant with severe type Ⅱbronchopulmonary dysplasia(BPD)during the transition period from hospitalization to home.The care of the infant was provided one-on-one by a BPD specialist nurse throughout the period.The key points of transitional care from hospitalization to home include:implementing tracheotomy and mechanical ventilation care to ensure stable blood oxygen saturation of the infant;providing nutritional support to improve the nutritional status of the infant;implementing step-by-step rehabilitation measures to improve the neuromotor development of the infant;implementing family integrated care to promote the primary caregivers of the infant to master nursing knowledge and skills;conducting personalized discharge follow-up with a multidisciplinary team to improve the quality of home care for this infant.After being hospitalized for 106 days,the infant was successfully discharged with a tracheotomy tube.At the age of 2 years and 6 months,a tracheotomy closure surgery was performed.After the surgery,the infant was able to breathe autonomously without symptoms of breathing difficulties and returned to normal family life.

Objective To evaluate the scientificity,transparency and applicability of Chinese guidelines and expert consensuses on nursing published in 2022,in order to improve the quality of guidelines and consensuses.Methods Databases including Medline,Embase,Web of Science,CBM,CNKI,WanFang database,Chinese Medical Journal,and related websites were electronically searched,as well as China Hong Kong,Macao and Taiwan medical journals,to collect Chinese guidelines and expert consensuses on nursing from January to December 2022.STAR tool was used to evaluate the quality of each guidelines and consensuses by 3 assessors independently.Total score,scoring rate of each domain and item were adopted to analyze the outcomes.Results A total of 3 guidelines and 33 expert consensuses were included.The total guidelines and expert consensuses STAR score(33.5±14.3).The quality of guidelines and consensuses was low.The quality of guidelines was moderate with average score of 55.1,and the quality of consensuses was low with average score of 31.5.The included guidelines and consensuses had a highest score rate(52.4％)in the domain of recommendation.Among 39 items of STAR tool,the top 4 items including listing participants and institutions,explaining additional instructions for implementation,describing consensus method,and listing references for recommendations had a high score rate of 100％,83.3％,77.8％,75.0％respectively.However,the items of registration,providing registration information,protocols being searched on public platforms and explaining the role of funding had a low score rate,urgent need for attention and upgrading.Conclusion The overall quality of the Chinese guidelines and expert consensuses on nursing published in 2022 was low.As a medical and nursing practice guidance document,the quality of guidelines and expert consensuses should be improved by encouraging registration,strengthening management of interest conflict,enhancing the rigor of guideline developing process,and expanding the dissemination.

Objective:To observe the effects of Sanjia Powder on myocardial fibrosis in diabetic cardiomyopathy (DCM) model rats; To elaborate its mechanism.Methods:A DCM rat model was constructed using STZ single intraperitoneal injection combined with high-sugar and high-fat feeding. The model rats were divided into model group, TCM group, Western medicine group, miR-21 inhibition group, and miR-21 inhibition control group using a random number table method, with 10 rats in each group; another 10 SD rats were set as normal group. TCM group was orally administered with Sanjia Powder water decoction at a dose of 6.2 g/kg, and the Western medicine group was administered metformin 250 mg/kg + enalapril 45 mg/kg by gavage. miR-21 inhibition group, miR-21 inhibition control group, normal group, and model group were given the same volume of distilled water by gavage, once a day, for 4 weeks; at the same time, the normal group, the model group, TCM group, and the Western medicine group were injected with the same amount of normal saline in the tail vein. The miR-21 inhibition group received tail vein injection of miR-21 inhibitor at a dose of 20 mg/kg, and the miR-21 inhibition control group received tail vein injection of miR-21 inhibitor NC at a dose of 20 mg/kg, twice a week, for 4 weeks. The morphological changes of myocardial tissue were observed using HE; the expression of Collagen-Ⅰ in myocardial tissue was detected using Western Blot; the expressions of endothelial cell marker CD31 and stromal cell marker FSP1 in myocardial tissue were detected using immunofluorescence method.Results:Compared with the model group, the pathological morphology of myocardial tissue improved in the TCM group, Western medicine group, and miR-21 inhibition group, while the expressions of Collagen-Ⅰ and FSP1 decreased ( P<0.01) and the expression of CD31 increased ( P<0.01); there was no statistically significant difference in the expressions of Collagen-Ⅰ, CD31, and FSP1 between the TCM group and the miR-21 inhibition group ( P>0.05). Conclusion:Sanjia Powder can improve myocardial fibrosis in rats with diabetic cardiomyopathy, and its mechanism may be related to the up-regulation of CD31 expression and down-regulation of FSP1 expression, thereby inhibiting endothelial mesenchymal transition, and may also be related to the inhibition of miR-21 expression.
