BACKGROUND: Lung cancer is currently the most prevalent malignancy and the leading cause of cancer deaths worldwide. Although the early stage non-small cell lung cancer (NSCLC) presents a relatively good prognosis, a considerable number of lung cancer cases are still detected and diagnosed at locally advanced or late stages. Surgical treatment combined with perioperative multimodality treatment is the mainstay of treatment for locally advanced NSCLC and has been shown to improve patient survival. Following the standard methods of neoadjuvant therapy, perioperative management, postoperative adjuvant therapy, and other therapeutic strategies are important for improving patients' prognosis and quality of life. However, controversies remain over the perioperative management of NSCLC and presently consensus and standardized guidelines are lacking for addressing critical clinical issues in multimodality treatment. METHODS: The working group consisted of 125 multidisciplinary experts from thoracic surgery, medical oncology, radiotherapy, epidemiology, and psychology. This guideline was developed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. The clinical questions were collected and selected based on preliminary open-ended questionnaires and subsequent discussions during the Guideline Working Group meetings. PubMed, Web of Science, Cochrane Library, Scopus, and China National Knowledge Infrastructure (CNKI) were searched for available evidence. The GRADE system was used to evaluate the quality of evidence and grade the strengths of recommendations. Finally, the recommendations were developed through a structured consensus-building process. RESULTS: The Guideline Development Group initially collected a total of 62 important clinical questions. After a series of consensus-building conferences, 24 clinical questions were identified and corresponding recommendations were ultimately developed, focusing on neoadjuvant therapy, perioperative management, adjuvant therapy, postoperative psychological rehabilitation, prognosis assement, and follow-up protocols for NSCLC. CONCLUSIONS This guideline puts forward reasonable recommendations focusing on neoadjuvant therapy, perioperative management, adjuvant therapy, postoperative psychological rehabilitation, prognosis assessment, and follow-up protocol of NSCLC. It standardizes perioperative multimodality treatment and provides guidance for clinical practice among thoracic surgeons, medical oncologists, and radiotherapists, aiming to reduce postoperative recurrence, improve patient survival, accelerate recovery, and minimize postoperative complications such as atelectasis.

OBJECTIVES: To explore the status and risk factors of neuropsychological development in small for gestational age (SGA) infants at corrected 12-24 months of age. METHODS: Clinical data were retrospectively collected for 754 SGA infants at corrected ages 12-24 months in Shenzhen Bao'an Women and Children's Hospital between April 2018 and December 2023. Developmental quotient (DQ) levels were analyzed. According to the presence of global developmental delay (GDD), participants were divided into a GDD group (71 cases) and a control group (683 cases), and the incidence and influencing factors of GDD were investigated. RESULTS: In the high-risk preterm SGA group, the total DQ and DQ in all domains were lower than in the full-term SGA group (P<0.017). The overall incidence of GDD was 9.4% (71/754) and increased with decreasing gestational age (P<0.017). Compared with the control group, the GDD group had higher proportions of males; low-risk and high-risk preterm birth; mothers with less than a bachelor's degree; multiple birth; neonatal hypoglycemia; neonatal pneumonia; neonatal respiratory distress syndrome; bronchopulmonary dysplasia; and, at corrected 12-24 months, low body weight, growth retardation, and microcephaly. The length of neonatal hospital stay was longer in the GDD group than in the control group (P<0.05). The weight-for-age Z score, length-for-age Z score, and head circumference-for-age Z score at birth and at corrected 12-24 months were lower in the GDD group than in the control group (P<0.05). Multivariable logistic regression showed that male sex and maternal education below a bachelor's degree were independent risk factors for GDD in SGA infants (P<0.05). CONCLUSIONS Neuropsychological development in preterm SGA infants is comparatively delayed; male SGA infants born to mothers with less than a bachelor's degree should receive priority attention.

Objective:To investigate the Helicobacter pylori ( H. pylori) infection of Tibetan families and individuals in the Western Sichuan Plateau region and explore the related factors which affected H. pylori infection. Methods:This was a single-center cross-sectional study. Questionnaires were collected from 50 Tibetan families including 155 individuals in Western Sichuan Plateau region during March to May 2023. The 13C-urea breath test was performed to confirm the current infection status of participants. Binary logistic regression were used to analyze the related factors associated with H. pylori infection. Results:Among the 50 Tibetan households, the individual-based H. pylori infection rate was 47.10%(73/155), with two out of nine children and 48.63%(71/146) adults infected. The age group of 18 to 40 years had the highest infection rate (55.00%, 11/20). The prevalence of infection based on family was 80.00%(40/50), of which 16.00%(8/50) had all family members infected. Of the 59 couples surveyed, 23.73%(14/59) were both infected, and 45.76%(27/59) had one person infected. Of the six families which had children and adolescents, two households had their children infected. Logistic regression analysis showed that size of the family was a factor related to H. pylori infection (odds ratio=3.038, 95% confidence interval 1.043 to 10.491, P=0.042). Conclusions:The family-based H. pylori infection rate is relatively high in Tibetan residents in the Western Sichuan Plateau, and larger family size is related with higher risk of H. pylori infection within the family.

Objective:To analyze the distribution pattern of TCM syndrome elements in elderly patients with sepsis and septic shock, as well as the relationship between TCM syndrome elements, Sepsis Sequential Organ Failure Score (SOFA), Acute Physiology and Chronic Health Score Ⅱ (APACHE Ⅱ), and short-term mortality prognosis.Methods:A retrospective analysis was conducted on the clinical data of 58 patients treated in the Emergency Department and ICU of Dongzhimen Hospital of Beijing University of Chinese Medicine and the Third Affiliated Hospital of Beijing University of Chinese Medicine from January 1, 2021, to May 1, 2022. The patients were divided into a sepsis group of 38 cases and a septic shock group of 20 cases based on disease type. Basic information, TCM syndromes, SOFA score, and APACHE Ⅱ score of the two groups were collected. The survival and death statuses of the two groups within 28 days of admission were separately analyzed. Association rule analysis was used to investigate the distribution pattern of TCM syndromes in patients, and logistic regression analysis was performed to explore the relationship between TCM syndromes, SOFA score, APACHE Ⅱ score, and death prognosis.Results:In the sepsis group, the main TCM syndromes included yin deficiency, lung, phlegm, qi deficiency, blood stasis, heat, and yang deficiency; while in the septic shock group, the main TCM syndromes were yin deficiency, lung, yang deficiency, and qi deficiency. Multifactor logistic regression analysis showed that in the sepsis group, liver syndromes [ OR (95% CI)=0.080 (0.011, 0.578), P=0.012], meridians and collaterals [ OR (95% CI)=0.088 (0.011, 0.718), P=0.024], SOFA score [ OR (95% CI)=0.524 (0.310, 0.886), P=0.016], and APACHE Ⅱ score [ OR (95% CI)=0.426 (0.186, 0.977), P=0.044] were independent influencing factors for patient mortality prognosis. In the septic shock group, phlegm [ OR (95% CI)=0.014 (0.001, 0.267), P=0.005], meridians and collaterals [ OR (95% CI)=0.041 (0.003, 0.618), P=0.021], yang deficiency [ OR (95% CI)=0.028 (0.002, 0.427), P=0.010], SOFA score [ OR (95% CI)=0.543 (0.310, 0.950), P=0.032], and APACHE Ⅱ score [ OR (95% CI)=0.633 (0.408, 0.985), P=0.042] were independent influencing factors for patient mortality prognosis. Conclusions:The sepsis group mainly exhibits a mixture of deficiency and excess, while the septic shock group predominantly shows deficiency. Qi deficiency and yin deficiency are consistent throughout the disease progression. Meridians and collaterals, high SOFA score, and high APACHE Ⅱ score in elderly patients with sepsis and septic shock may indicate a poorer prognosis.

Objective:To understand the prevalence, blood pressure control, and influencing factors of hypertension in residents aged 35-75 years in Jiangsu Province, and provide data support and basis for hypertension prevention and treatment.Methods:A stratified cluster sampling method was adopted to conduct community population surveys in 22 districts and counties in 12 prefectures in Jiangsu from 2021 to 2022. A total of 123 531 permanent residents aged 35-75 years were included in the study. The questionnaire survey collected the information about the demographic characteristics, disease history, lifestyle, and control of hypertension of study subjects. Statistical software SPSS 23.0 was used for χ2 test and multivariate logistic regression analysis, and Joinpoint 4.9.1.0 software was used to evaluate the trend of age change. Results:The standardized prevalence of hypertension in study subjects was 46.60%, the prevalence was higher in men than in women, and in rural residents than in urban residents, and the standardized blood pressure control rate was 11.24%, and it was lower in men than in women and in rural residents than in urban residents. The hypertension prevalence and control rates showed increasing trends with age (both P<0.001). The multivariate analysis results showed that being man, older age, being rural resident, higher frequency of alcohol consumption, marital status of being separated and widowed, overweight and obese, abdominal obesity and stroke, diabetes mellitus and dyslipidaemic diseases histories, and family history of hypertension were risk factors for hypertension, and being man, being rural resident, living north area, higher frequency of alcohol consumption, and obesity were risk factors for blood pressure control. Conclusions:The prevalence of hypertension in residents aged 35-75 years in Jiangsu was high, and the rate of blood pressure control was low. It is suggested to take integrated intervention measures, especially in in rural residents and people with low levels of education to reduce the disease burden of the patients.

Objective To compare the advantages of robot assisted and DSA guided PBC for the treatment of trigeminal neuralgia.Methods A retrospective clinical analysis was conducted on 85 patients(28 in robot group and 57 in DSA group)who underwent robot assisted and DSA guided PBC surgery in a same center from September 2021 to February 2024.The single puncture success rate,improvement rate of VAS score,clinical efficacy rate,incidence of complications,average surgical time and fluoroscopy time were compared between the two groups.Results There was no statistically significant difference between the two groups in terms of single puncture success rate(96.43% vs.84.21% ),VAS improvement rate[88.9% (77.78%,100.00% )vs.88.89% (55.56%,100.00% )],clinical effective rate(92.86% vs.94.74% ),and total incidence of complications(35.09% vs.42.11% )(P>0.05).The average surgical time was significantly higher in the robot group[38.50(35.00,48.00)min]than the DSA group[19.00(15.00,25.50)min],and the average fluoroscopy time in the robot group[13.00(12.00,15.75)s]was significantly lower than the DSA group[194.00(152.50,259.50)s].The difference in average surgical and fluoroscopy time between the two groups was statistically significant(P<0.05).Conclusion DSA guided surgery has more advantages in centers with a large number of patients and a pursuit of efficiency.The robot assisted surgical puncture process is safe and controllable and patient radiation exposure time is short,thereby having high clinical application and promotion value.

Objective:To explore the risk factors of severe acute kidney injury (AKI) in septic patients, and to establish an hour-specific prediction model.Methods:Based on the information of septic patients in the Medical Information Mart for Intensive Care-Ⅳ (MIMIC-Ⅳ) database, general information, comorbidities, vital signs, severity scoring system, laboratory indicators, invasive operations and medication use were recorded. The enrolled patients were randomized into a training set and a validation set according to a ratio of 7∶3. AKI was diagnosed according to the guidelines of Kidney Disease: Improving Global Outcome (KDIGO). Based on Lasso regression and Cox regression, the risk factors of severe AKI (AKI stage 2 and stage 3) in septic patients were analyzed and hour-specific prediction model were established. Consistency index (C-index), area under the receiver operator characteristic curve (AUC) and calibration curve were used to assess the predictive efficacy of the model.Results:A total of 20 551 septic patients were enrolled, including 14 385 patients in the training set and 6 166 patients in the validation set. Multivariate Cox regression analysis showed that atrial fibrillation [hazard ratio ( HR) = 1.266, 95% confidence interval (95% CI) was 1.150-1.393], heart failure ( HR = 1.348, 95% CI was 1.217-1.493), respiratory failure ( HR = 1.565, 95% CI was 1.428-1.715), heart rate ( HR = 1.004, 95% CI was 1.002-1.007), mean arterial pressure ( HR = 1.245, 95% CI was 1.126-1.377), lactic acid ( HR = 1.051, 95% CI was 1.025-1.077), simplified acute physiology score Ⅱ (SAPSⅡ, HR = 1.019, 95% CI was 1.016-1.023), serum creatinine ( HR = 1.171, 95% CI was 1.127-1.216), anion gap ( HR = 1.024, 95% CI was 1.010-1.038), serum potassium ( HR = 1.155, 95% CI was 1.079-1.236), white blood cell count ( HR = 1.006, 95% CI was 1.003-1.009) and furosemide use ( HR = 0.414, 95% CI was 0.368-0.467) were independently associated with severe AKI in septic patients (all P < 0.01). The above predictors were applied to construct an hour-specific prediction model for the occurrence of severe AKI in septic patients. The C-index of the prediction model was 0.723 and 0.735 in the training and validation sets, respectively. The AUC for the occurrence of severe AKI at 12, 24, and 48 hours were 0.795 (95% CI was 0.782-0.808), 0.792 (95% CI was 0.780-0.805), and 0.775 (95% CI was 0.762-0.788) in the training set, and the AUC were 0.803 (95% CI was 0.784-0.823), 0.791 (95% CI was 0.772-0.810), and 0.773 (95% CI was 0.752-0.793) in the validation set, respectively. The calibration curves of the two cohorts were in good agreement. Conclusion:The hour-specific prediction model effectively identifies high-risk septic patients for developing severe AKI within 48 hours, aiding clinicians in stratifying patients for early therapeutic interventions to improve outcomes.
