"Weibing" is a fundamental concept in traditional Chinese medicine (TCM), representing a transitional state characterized by diminished self-regulatory abilities without overt physiological or social dysfunction. This perspective delves into the biological foundations and quantifiable markers of Weibing, aiming to establish a research framework for early disease intervention. Here, we propose the "Health Quadrant Classification" system, which divides the state of human body into health, sub-health, disease-susceptible state, and disease. We suggest the disease-susceptible stage emerges as a pivotal point for TCM interventions. To understand the intrinsic dynamics of this state, we propose laboratory and clinical studies utilizing time-series experiments and stress-induced disease susceptibility models. At the molecular level, bio-omics technologies and bioinformatics approaches are highlighted for uncovering intricate changes during disease progression. Furthermore, we discuss the application of mathematical models and artificial intelligence in developing early warning systems to anticipate and avert the transition from health to disease. This approach resonates with TCM's preventive philosophy, emphasizing proactive health maintenance and disease prevention. Ultimately, our perspective underscores the significance of integrating modern scientific methodologies with TCM principles to propel Weibing research and early intervention strategies forward.

BACKGROUND: Death burden of stroke is severe with over one-third rural residents in China, but there is still a lack of specific national and high-quality reports on the urban-rural differences in stroke burden, especially for subtypes. We aimed to update the understanding of urban-rural differences in stroke deaths. METHODS: This is a descriptive observational study. Data from the national mortality surveillance system, which covers 323.8 million with 605 disease surveillance points (DSPs) across all 31 provinces, municipalities, and autonomous regions in China. All deaths from stroke as the underlying cause from 2015 to 2020 according to DSPs. Crude mortality rate and age-standardized mortality rate (ASMR) were estimated through DSPs. Average annual percentage change was used to explain the change in mortality rate. RESULTS: From 2015 to 2020, the majority of deaths from all stroke subtypes occurred in rural areas. There were significant differences between the changes of urban and rural ASMRs. On the whole, the changes in urban areas were evidently better, and the ASMR differences were basically expanding. Stroke ASMR in urban China decreased by 15.5%. The rural ASMR of ischemic stroke increased by 12.9%. The rural and urban ASMRs of intracerebral hemorrhage decreased by 24.9% and 27.4%, and those of subarachnoid hemorrhage decreased by 29.5% and 40.4%, respectively. The highest ASMRs of all stroke subtypes and the increasing trend of ischemic stroke ASMR make rural males the focus of stroke management. CONCLUSIONS The death burden of stroke varies greatly between urban and rural China. Rural residents face unique challenges.

Objective:To detect the expression of Silent Information Regulator 1 (SIRT1), phosphorylated P53 protein (P53 protein), and Survivin in pancreatic cancer tissues, and to analyze their relationship with the prognosis of pancreatic cancer.Methods:A retrospective analysis was conducted on the clinical data of 102 patients with pancreatic cancer admitted to the Affiliated Hospital of Yan'an University from January 2020 to January 2023. The expression levels of SIRT1, P53, and Survivin in pancreatic cancer tissues and adjacent non-cancerous tissues were determined. Patients were followed up for 12-18 months and were divided into a survival group ( n = 59 and a death group ( n = 43) based on their survival status. The relationship between the expression of SIRT1, P53, and Survivin and the patients' pathological characteristics and prognosis was analyzed. Results:The positive expression rates of SIRT1, P53, and Survivin in pancreatic cancer tissues were 66.67% (68/102), 71.57% (73/102), and 73.53% (75/102), respectively, all of which were significantly higher than the rates in adjacent non-cancerous tissues, which were 26.47% (27/102), 29.41% (30/102), and 31.37% (32/102) ( χ2 = 33.11, 36.25, 36.34, all P < 0.001). Among patients with tumor stages Ⅱ-Ⅲ, low differentiation, and lymphatic metastasis, the positive rates of SIRT1 [82.61% (38/46), 76.06% (54/71), 81.82% (27/33)], P53 [84.78% (39/46), 80.28% (57/71), 87.88% (29/33)], and Survivin [86.96% (40/46), 81.69% (57/71), 87.88% (29/33)] were significantly higher than those in patients with tumor stage Ⅰ, moderate to high differentiation, and without lymphatic metastasis [SIRT1: 53.57% (30/56), 45.16% (14/31), 59.42% (41/69); P53: 60.71% (34/56), 51.61% (16/31), 63.77% (44/96); Survivin: 62.50% (35/56), 54.84% (17/31), 66.67% (46/96), χ2 SIRT1 = 9.58, 9.26, 5.04; χ2 P53 = 7.19, 8.71, 6.37; χ2 Survivin = 11.36, 7.99, 5.16, all P < 0.05]. The survival rates of patients with positive expression of SIRT1, P53, and Survivin in cancer tissues were 47.06% (32/68), 49.32% (36/73), and 49.33% (37/75), respectively, all of which were lower than the survival rates of patients with negative expression of SIRT1, P53, and Survivin, which were 79.40% (27/34), 79.31% (23/29), and 81.48% (22/27) (Log Rank χ2 = 8.79, 10.98, 12.65, all P < 0.05). In the survival group, the proportions of patients with tumor stages Ⅱ-Ⅲ, low differentiation, lymphatic metastasis, and positive expression of SIRT1, P53, and Survivin were 45.65% (21/46), 49.30% (35/71), 39.39% (13/33), 47.06% (32/68), 49.32% (36/73), and 49.33% (37/75), all of which were lower than the corresponding rates in patients with tumor stage Ⅰ, moderate to high differentiation, no lymphatic metastasis, and negative expression of SIRT1, P53, and Survivin, which were 67.86% (38/56), 77.42% (24/31), 66.67% (46/69), 79.41% (27/34), 79.31% (23/29), and 81.48% (22/27) ( χ2 = 5.10, 6.99, 6.80, 9.73, 7.65, 8.41, all P < 0.05). Tumor stage Ⅱ-Ⅲ ( OR = 2.413), low differentiation ( OR = 3.527), lymphatic metastasis ( OR = 3.077), positive SIRT1 expression ( OR = 4.339), positive P53 expression ( OR = 3.940), and positive Survivin expression ( OR = 4.519) were all identified as risk factors for poor prognosis in patients with pancreatic cancer (all P < 0.05). Conclusions:The expression of SIRT1, P53, and Survivin in the cancer tissues of patients with pancreatic cancer is closely associated with tumor stage, differentiation, and lymphatic metastasis. Additionally, the expression levels of SIRT1, P53, and Survivin are all significant factors influencing patient prognosis. Monitoring their expression can aid in the clinical prediction of patient outcomes.

OBJECTIVE: To compare the accuracy and effectiveness of orthopaedic robot-assisted minimally invasive surgery versus open surgery for limb osteoid osteoma. METHODS: A clinical data of 36 patients with limb osteoid osteomas admitted between June 2016 and June 2023 was retrospectively analyzed. Among them, 16 patients underwent orthopaedic robot-assisted minimally invasive surgery (robot-assisted surgery group), and 20 patients underwent tumor resection after lotcated by C-arm X-ray fluoroscopy (open surgery group). There was no significant difference between the two groups in the gender, age, lesion site, tumor nidus diameter, and preoperative pain visual analogue scale (VAS) scores ( P>0.05). The operation time, lesion resection time, intraoperative blood loss, intraoperative fluoroscopy frequency, lesion resection accuracy, and postoperative analgesic use frequency were recorded and compared between the two groups. The VAS scores for pain severity were compared preoperatively and at 3 days and 3 months postoperatively. RESULTS: Compared with the open surgery group, the robot-assisted surgery group had a longer operation time, less intraoperative blood loss, less fluoroscopy frequency, less postoperative analgesic use frequency, and higher lesion resection accuracy ( P<0.05). There was no significant difference in lesion resection time ( P>0.05). All patients were followed up after surgery, with a follow-up period of 3-24 months (median, 12 months) in the two groups. No postoperative complication such as wound infection or fracture occurred in either group during follow-up. No tumor recurrence was observed during follow-up. The VAS scores significantly improved in both groups at 3 days and 3 months after surgery when compared with preoperative value ( P<0.05). The VAS score at 3 days after surgery was significantly lower in robot-assisted surgery group than that in open surgery group ( P<0.05). However, there was no significant difference in VAS scores at 3 months between the two groups ( P>0.05). CONCLUSION Compared with open surgery, robot-assisted resection of limb osteoid osteomas has longer operation time, but the accuracy of lesion resection improve, intraoperative blood loss reduce, and early postoperative pain is lighter. It has the advantages of precision and minimally invasive surgery.

Vascular stents are an essential tool in cardiovascular interventional therapy, and their demand is growing with the increasing incidence of cardiovascular diseases. Compared with permanent stents, which are prone to in-stent restenosis, and drug-eluting stents, which may cause late stent thrombosis, biodegradable stents offer advantages. After providing early radial support to prevent elastic recoil, biodegradable stents gradually degrade, allowing the vessel to regain its natural physiological contractility and undergo positive remodeling. A review of the current mainstream biodegradable metal stents, magnesium-based, iron-based, and zinc-based alloys, shows promising findings in both preclinical and clinical research. Magnesium-based stents exhibit good operability and low thrombosis rates, but their limitations include rapid degradation, hydrogen evolution, and significant pH changes in the microenvironment. Iron-based stents demonstrate excellent mechanical strength, formability, biocompatibility, and hemocompatibility, but their slow corrosion rate hampers broader clinical application; accelerating degradation remains key. Zinc-based alloys have a moderate degradation rate but relatively low mechanical strength; enhancing stent strength by alloying with other elements is the main improvement direction for zinc-based stents.

Meanwhile, combining the two-factor theory and practical experience, the problems that existed in the innovation incentive policy of public hospitals for young medical talents were analyzed, and the corresponding countermeasures were proposed to build the innovation incentive path of young medical talents under the two-factor theory.Results:Based on analyzing the demand characteristics of young medical talents, managers should distinguish health care factors and incentive factors, and implement incentives from both aspects. Provide incentives through improving the personal sense of achievement, creating a personal growth environment, and promoting professional titles to stimulate young talents' innovation motivation; implement health care factors from aspects of working conditions, material benefits, salary levels, etc.Conclusions:As a new concept of development, high-quality development is not only reflected in scientific and technological innovation-driven, but also in the innovation of management mechanisms so that institutional innovation becomes the driving force for high-quality development.

Objective:To evaluate the laparoscopic sleeve gastrectomy combined with hiatal hernia repair surgery for weight loss and antireflux.Methods:This study included 21 obese patients with gastroesophageal reflux who underwent laparoscopic sleeve gastrectomy at the Weight Loss Metabolism Center of the Department of Hepatobiliary and Pancreatic Surgery of Zhejiang Provincial People's Hospital from Dec 2019 to Dec 2020. Patients were divided into simple bariatric surgery group (9 cases) and simultaneous combined surgery group (12 cases).Results:In the combined surgery group, 1 case had postoperative gastric leakage. The postoperative body weight, waist circumference, and BMI indexes of the two groups showed a downward trend ( F=5.154, P=0.013; F=14.319, P<0.001; F=6.725, P=0.004). There was a statistically significant difference in the excess weight loss in both the two groups at 6 months after the operation compared to 1 month after the operation ( t=8.927, P<0.001; t=8.926, P<0.001). There was no statistically significant difference in postoperative lower esophageal sphincter resting pressure and Gerd symptom score in the bariatric surgery group compared with preoperative ( t=-0.891, P=0.507; t=0.629, P=0.298). The postoperative Gerd symptom score of the patients in the combined surgery group was significantly lower than that before the operation, and the resting pressure of the lower esophageal sphincter was significantly higher than that before the operation, ( t=-10.539, P<0.001; t=5.066, P=0.038). Conclusion:Combined surgery have the same weight loss effect as in simple bariatric surgery in obese patients with gastroesophageal reflux, in addition to stronger anti-reflux effect.

Objective:To study the relationship between the expression of carnitine palmitoyltransferase 1α (CPT1α) and progression of renal interstitial fibrosis and chronic kidney disease (CKD), and to evaluate the value of CPT1α as a biomarker in pathological diagnosis of renal interstitial fibrosis and CKD.Methods:As a retrospective cohort study, information of CKD patients dignosed with tubulointerstitial fibrosis by renal biopsy and receiving follow-up from March 1, 2010 to July 30, 2017 in the Second Affiliated Hospital of Nanjing Medical University were collected. Renal tissues were stained by immunohistochemistry to detect the expression of CPT1α protein and then divided into three groups according to the quartile of proportion of CPT1α positive staining cells, including group Q1(>67.89%), group Q2(49.84%-67.89%) and group Q3(<49.84%). The degree of renal interstitial fibrosis was measured by Masson staining and lipid deposition was represented by Bodipy staining. Messenger RNA of CPT1α and collagen as well as other extracellular matrix genes were detected by real time-PCR. Relationships between proportion of CPT1α positive staining cells and renal interstitial fibrosis and renal function were analyzed by linear regression analysis. The relationship between CPT1α positive cell number ratio and renal function progression was measured by Pearson correlation analysis and generalized linear model. The effect of lipid-lowering medicine on renal function of CKD patients was analyzed by paired comparative analysis.Results:Ninety patients with CKD were included in this study. Renal interstitial fibrosis and lipid droplets deposition area increased in Q2/Q3 group compared with Q1 group by Masson and Bodipy staining (all P<0.05). Messenger RNA level of extracellular matrix-related proteins increased in Q2/Q3 group by real time-PCR than those of Q1 group (all P<0.05). Linear regression analysis showed that fibrosis area was negatively correlated with the proportion of CPT1α positive staining cells ( r=-0.309, P<0.01). The baseline expression of CPT1α in renal issues was negatively related with serum creatinine (Scr) ( r=-2.801, P<0.001), positively related with estimated glomerular filtration rate (eGFR) ( r=1.240, P<0.001). After a medium follow-up of 3.47 years, CPT1α positive cell number ratio was positively correlated with eGFR change rate by Pearson analysis ( r=0.220, P=0.038). Paired stratified analysis showed that taking lipid-lowering medicines attenuated the decrease of eGFR in Q2 group and Q3 group but not in Q1 group (both P<0.05). Conclusions:The decline of CPT1α in renal tissues of CKD patients is associated with the increase of Scr, the decrease of eGFR and renal interstitial fibrosis. CPT1α is a promising molecular marker to evaluate the degree of renal fibrosis and the progression of CKD.
