Objective:To investigate the survival outcomes and prognostic factors in patients undergoing radical resection for pancreatic body and tail cancer.Methods:A retrospective case series study was conducted on 992 patients who underwent radical resection for pancreatic body and tail cancer at the Pancreatic Center of the First Affiliated Hospital of Nanjing Medical University from January 2016 to June 2024. In this study, 577 (58.2%) were male and 415 (41.8%) were female,with an age of (65±9) years (range: 26 to 86 years). Follow-up continued until June 2024. Survival rates were estimated using the Kaplan-Meier method,and prognostic factors were identified using univariate and multivariate Cox proportional hazards models.Results:Among 992 patients,open surgery was the predominant approach (89.1%, 884/992), and radical antegrade modular pancreatosplenectomy (RAMPS) was performed in 317 patients (32.0%). Combined organ resection,venous resection,and arterial resection were performed in 23.5%, 9.3%,and 11.2% of patients,respectively. The rates of R0, R1-1 mm, and R1-direct resections were 49.8% (494/992),41.5% (412/992), and 8.7% (86/992),respectively. Stage ⅡB was the most common TNM stage (32.2%,319/992). A total of 801 patients (80.8%) received adjuvant chemotherapy. The median follow-up period was 32.0(8.8) months(range:3.2 to 105.3 months),during which 508 patients (51.2%) died. The overall median survival (OS) was 26.4 months,with 1-,3-, and 5-year survival rates of 79.0%,40.0%, and 29.0%, respectively. In the recent five years (from 2020 to 2024), the median OS improved significantly to 34.1 months compared to 20.0 months from 2016 to 2019 ( P<0.01). Histological subtype analysis showed that the median OS time was 26.7 months for pancreatic ductal adenocarcinoma (PDAC, n=855),58.9 months for invasive intraductal papillary mucinous carcinoma (IPMC, n=32),and 15.7 months for adenosquamous carcinoma of pancreas (ASCP, n=73) ( P=0.001). Among PDAC patients, adjuvant chemotherapy significantly improved survival (29.1 months vs. 14.4 months, P<0.01);in IPMC patients, adjuvant chemotherapy also extended survival (65.7 months vs. 58.9 months, P=0.047). Although ASCP patients receiving chemotherapy had a longer median OS time than those without (18.8 months vs. 8.9 months),the difference was not statistically significant ( P=0.151). Multivariate Cox regression analysis in PDAC patients indicated that adjuvant chemotherapy, R0 resection, T stage,N stage,and tumor differentiation were independent prognostic factors ( P<0.01). The median OS time by TNM stage was:not reached for stage ⅠA, 51.6 months for ⅠB, 25.5 months for ⅡA, 23.7 months for ⅡB, 23.0 months for Ⅲ, and 14.4 months for Ⅳ. The median OS time for R0,R1-1 mm,and R1-direct resections was 34.1,24.7,and 15.7 months,respectively ( P<0.01). Conclusion:Adjuvant chemotherapy,R0 resection,tumor stage,and differentiation are independent prognostic factors for pancreatic body and tail cancer.

Objective To explore the application effect of personalized osteotomy guide plate in high tibial osteotomy for patients with knee osteoarthritis(KOA).Methods A total of 99 patients with KOA who underwent open wedge high tibial osteotomy(OWHTO)in our hospital from January 2022 to January 2023 were selected and randomly divided into a study group(50 cases)and a control group(49 cases)using a random number table method.The control group received traditional medial OWHTO treatment,and the study group received a combination of medial OWHTO and personalized osteotomy guide plate treatment.The indexes of operation and postoperative rehabilitation,serum inflammatory stress factor[C-reactive protein(CRP),tumor necrosis factor-α(TNF-α),cortisol(Cor),adrenocorticotropin(ACTH)],anatomical structure of knee joint[tibial plateau posterior Angle(PTSA),proximal medial tibial Angle(MPT A),hip knee ankle Angle(HKA)],knee function,ACL shape and function,postoperative complications were compared between the two groups.Results The amount of bleeding,the number of intraoperative fluoroscopy,and the postoperative drainage volume in the study group were(138.69±24.03)ml,(4.83±1.07)times,and(228.95±38.72)ml,respectively,which were all less than those in the control group(154.28±27.16)ml,(7.15±1.14)times,and(271.61±42.19)ml.In the study group,the operation time,incision length,and hospitalization time were(40.96±7.28)min,(8.96±0.85)cm,and(10.73±2.05)d,respectively,which were all shorter than those in the control group[(52.31±10.12)min,(9.51±1.03)cm,and(12.16±2.37)d],with statistically significant differences(P＜0.05).The levels of serum CRP,TNF-α,Cor,and ACTH in the study group on the 3rd day after the operation were(31.36±4.68)mg/L,(26.71±3.84)ng/ml,(241.28±27.45)ng/ml,and(18.65±3.01)pmol/L,respectively,which were lower than those in the control group[(35.07±5.16)mg/L,(30.29±4.15)ng/ml,(279.65±30.12)ng/ml,and(21.73±3.28)pmol/L,respectively],and the differences were statistically significant(P＜0.05).The Hospital for Special Surgery(HSS)knee score and Knee Society Score(KSS)of the study group at 12 months after surgery were(81.24±6.85)points and(78.26±6.14)points,respectively,which were higher than those of the control group[(78.08±6.42)points and(75.53±5.82)points,respectively],with statistically significant differences(P＜0.05);at the 12th month after surgery,the width of the ACL body in the study group was(5.68±0.71)mm,which was greater than that in the control group[(5.12±0.64)mm].The amount of anterior tibial displacement was(5.81±0.43)mm,which was smaller than that in the control group(6.19±0.41)mm,and the differences were statistically significant(P＜0.05);the incidence of postoperative complications in the study group was 4.00％,which was lower than that in the control group(18.37％),and the difference was statistically significant(P＜0.05).Conclusion The combined treatment of medial OWHTO and personalized osteotomy guide plate can reduce surgical trauma in patients with KOA,lower the incidence of complications,facilitate patient recovery,while maintaining the morphology and function of the ACL,and improving prognosis.

Objective: To investigate the objective characteristics of tongue manifestation in different stages of damp-heat syndrome in diabetic kidney disease (DKD). Methods: A cross-sectional study enrolled 134 patients with DKD G3-5 stages who met the diagnostic criteria for damp-heat syndrome in DKD. The patients were treated at Dongzhimen Hospital, Beijing University of Chinese Medicine, from May 2023 to January 2024. The patients were divided into three groups: DKD G3, DKD G4, and DKD G5 stage, with 53, 33, and 48 patients in each group, respectively. Clinical general data (gender, age, and body mass index) and damp-heat syndrome scores were collected from the patients. The YZAI-02 traditional Chinese medicine (TCM) AI Tongue Image Acquisition Device was used to capture tongue images from these patients. The accompanying AI Open Platform for TCM Tongue Diagnosis of the device was used to analyze and extract tongue manifestation features, including objective data on tongue color, tongue quality, coating color, and coating texture. Clinical data and objective tongue manifestation characteristics were compared among patients with DKD G3-5 based on their DKD damp-heat syndrome status. Results: No statistically significant difference in gender or body mass index was observed among the three patient groups. The DKD G3 stage group had the highest age (P<0.05). The DKD G3 stage group had a lower score for symptoms of poor appetite and anorexia(P<0.05) than the DKD G5 group. No statistically significant difference was observed in damp-heat syndrome scores among the three groups. Compared with the DKD G5 stage group, the DKD G3 stage group showed a decreased proportion of pale color at the tip and edges of the tongue (P<0.05). The DKD G4 stage group exhibited an increased proportion of crimson at the root of the tongue, a decreased proportion of thick white tongue coating at the root, a decreased proportion of pale color at the tip and edges of the tongue, an increased hue value (indicating color tone) of the tongue color in the middle, an increased brightness value (indicating color lightness) of the tongue coating color in the middle, and an increased thickness of the tongue coating (P<0.05). No statistically significant difference was observed in other tongue color proportions, color chroma values, body characteristics, coating color proportions, coating color chroma values, and coating texture characteristics among the three groups. Conclusion Tongue features differ in different stages of DKD damp-heat syndrome in multiple dimensions, enabling the inference that during the DKD G5 stage, the degree of qi and blood deficiency in the kidneys, heart, lungs, liver, gallbladder, spleen, and stomach is prominent. Dampness is more likely to accumulate in the lower jiao, particularly in the kidneys, whereas heat evil in the spleen and stomach is the most severe. These insights provide novel ideas for the clinical treatment of DKD.

Infectious keratitis (IK) is a leading cause of blindness worldwide, primarily resulting from improper contact lens use, trauma, and a compromised immune response. The pathogenic microorganisms responsible for IK include bacteria, fungi, viruses, and Acanthamoeba. This review examines standard therapeutic agents for treating IK, including broad-spectrum empiric antibiotics for bacterial keratitis (BK), antifungals such as voriconazole and natamycin for fungal infections, and antiviral nucleoside analogues for viral keratitis (VK). Additionally, this review discusses therapeutic agents, such as polyhexamethylene biguanide (PHMB), for the treatment of Acanthamoeba keratitis (AK). The review also addresses emerging drugs and the challenges associated with their clinical application, including anti-biofilm agents that combat drug resistance and nuclear factor kappa-B (NF-κB) pathway-targeted therapies to mitigate inflammation. Furthermore, methods of Photodynamic Antimicrobial Therapy (PDAT) are explored. This review underscores the importance of integrating novel and traditional therapies to tackle drug resistance and enhance drug delivery, with the goal of advancing treatment strategies for IK.

Objective:To identify the change trajectory of intrinsic capacity in people aged ≥50 years in Shanghai and explore the impact of intrinsic capacity trajectory change on overall function and dalily life activities in this population.Methods:The longitudinal data from round 1 to 3 Study of Global Ageing and Adult Health in Shanghai were used. The total intrinsic ability scores from five dimensions of cognition, psychology, sensory, vitality and locomotion were calculated. The censored normal model of group-based trajectory was used to identify the trajectory of intrinsic capacity change over time. Linear regression model and multivariate logistic regression model were used to analyse the effects of different levels intrinsic capacity trajectory on the scores of the WHO Disability Assessment Schedule (WHODAS), the activity of daily living (ADL) and the instrumental activities of daily living (IADL).Results:A total of 2 302 study participants aged ≥50 years with 3 round complete data were included in this study, and 3 levels of intrinsic capacity trajectory were identified, low-level trajectory (9.3%), medium-level trajectory (41.7%), and high-level trajectory (49.0%). Compared with the high-level group, the medium-level and low-level groups had higher WHODAS scores, which increased by 3.578 (95% CI: 2.028-5.129) and 12.620 (95% CI: 9.951-15.289), respectively, and those with more severe disability and those in the low-level group were at higher risk for severe difficulty in ADLs ( OR=12.450, 95% CI: 4.310-35.966) and IADLs ( OR=5.479, 95% CI: 1.311-22.904). Conclusions:Heterogeneity in trajectory of intrinsic capacity exists in people aged ≥50 years in Shanghai. Middle-aged and elderly people with low initial level and rapid decline trajectory of intrinsic capacity are at greater risk for the decline of daily life ability and the increase of disability. It is necessary to strengthen the long-term dynamic monitoring and evaluation of the change trajectory of intrinsic capacity in this population.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To establish 30-day of age transcutaneous bilirubin (TcB) reference curves for healthy neonates, and to investigate regional variations in bilirubin dynamics.Methods:A multicenter retrospective cohort study was conducted. A total of 220 950 healthy neonates born at a gestational age of 35-<42 weeks, with a birth weight ≥2 000 g, who did not receive phototherapy within 60 h after birth were recruited. All of them underwent remote TcB monitoring using the Bilibaby remote jaundice monitoring system between August 1 st, 2020 and December 31 st, 2024 in 426 hospitals. TcB data were collected within the period from birth to 30-day of age. The P40, P75, and P95 of TcB values were calculated, and dynamic TcB curves for 30-day of age were constructed. Patterns of bilirubin change, rates of change, and transition outcomes were described. Regional comparisons between South and North were conducted using linear mixed-effects models for TcB trajectories and Pearson′s chi-square test for outcome differences. Results:A total of 220 950 neonates were included, of whom 101 711 (46.03%) were female. Gestational age at birth was (38.75±1.12) weeks, and birth weight was (3 272±417) g. TcB levels increased rapidly within 3-day of age, peaked at 4-6-day of age, with peak values at P40, P75, and P95 of 200.6, 239.7 and 275.4 μmol/L (11.8, 14.1 and 16.2 mg/dl), respectively. TcB levels gradually declined thereafter and stabilized after 13-day of age, with values at P40, P75, and P95 fluctuating between 147.9-159.8, 190.4-200.6, and 231.2-239.7 μmol/L (8.7-9.4, 11.2-11.8, 13.6-14.1 mg/dl), respectively. Notably, among neonates categorized as low-or low-intermediate-risk within 3-day of age, 6 700 (12.76%) progressed to intermediate-high or high risk between 4 and 30 days of age. Before 13-day of age, TcB levels in the southern regions were consistently higher than those in the northern regions ( P=0.039); from 14 to 30 days of age, the overall TcB levels had no statistically difference, but the temporal changes in TcB still showed regional differences (degrees of freedom=3, all interaction P<0.05). Among neonates classified as low-or low-intermediate risk within 3-day of age, 25 326 were from southern regions, of whom 4 254 (16.80%) progressed to intermediate-high or high risk between 4 and 30 days of age. In northern regions, 27 193 neonates were classified as low-or low-intermediate risk within 3-day of age, among whom 2 446 (8.99%) progressed to intermediate-high or high risk. The risk progression between the 2 regions had statistically difference ( χ2=716.49, P<0.001). Conclusions:A TcB percentile curve for neonates within 30-day of age was established, revealing that both the overall TcB level and its temporal trend were higher in southern than in northern newborns. These findings provide baseline data to support continuous management of neonatal jaundice.
