Objective: To investigate the prevalence levels and trends of overweight and obesity among adult residents in Zhejiang Province from 2015 to 2023, so as to provide a basis for developing regional weight management strategies. Methods: Permanent residents aged ≥18 years from Zhejiang Province who participated in the China Chronic Disease and Risk Factor Surveillance Project in 2015, 2018, and 2023 were selected as survey subjects. Data on sociodemographic information, height, weight and waist circumference were collected through questionnaire surveys and physical examinations. The prevalence of overweight, obesity, and central obesity were calculated and standardized using data from the Seventh National Population Census of Zhejiang Province in 2020. The Cochran-Armitage trend test was employed to analyze the trends in prevalence of overweight, obesity, and central obesity across different genders, ages and regions. Results: A total of 23 902 individuals were surveyed, comprising 10 985 males (45.96%) and 12 917 females (54.04%). Participants were aged ≥60 years, with 13 088 individuals accounting for 54.76%. There were 9 388 urban residents (39.28%) and 14 514 rural residents (60.72%). The standardized prevalence of overweight among residents increased from 30.05% in 2015 to 33.98% in 2023, the standardized prevalence of obesity increased from 7.67% to 15.22%, and the standardized prevalence of central obesity increased from 22.81% to 33.82%, all showed upward trends (all P<0.05). In 2015, 2018, and 2023, the standardized prevalence of overweight was higher in males than in females. In 2018 and 2023, the standardized prevalence of obesity and central obesity were higher in males than in females (all P<0.05). From 2015 to 2023, the standardized prevalence of overweight, obesity, and central obesity among both males and females showed upward trends (all P<0.05). In 2015, 2018 and 2023, the prevalence of central obesity showed an increasing trend with age (all P<0.05). From 2015 to 2023, upward trends were observed in the prevalence of overweight, obesity, and central obesity among residents aged 18-<45 years and aged ≥60 years, as well as in the prevalence of obesity and central obesity among residents aged 45-<60 years (all P<0.05). In 2015, 2018 and 2023, the standardized prevalence of overweight obesity were higher in urban areas than in rural areas, while the standardized prevalence of central obesity was lower in urban areas (all P<0.05). From 2015 to 2023, the standardized prevalence of overweight, obesity, and central obesity among both urban and rural areas showed upward trends (all P<0.05). Conclusion From 2015 to 2023, the prevalence of overweight, obesity, and central obesity among adult residents in Zhejiang Province showed increasing trends, with variations in prevalence levels and trends observed across genders, ages, and urban / rural areas.

This study explores the diagnosis and treatment of needle knife therapy for ankylosing spondylitis (AS) at middle and advanced stage based on the theory of meridian tendons, from a holistic perspective and syndrome differentiation. The treatment strategy includes "harmonizing yin and yang" to address root causes and "tendons-based release" to harmonize qi and blood, with the "tendons nodule points" as the core acupoint selection criterion. Based on this approach, the study systematically elaborates on two needle knife methods for AS: "governor vessel bone-piercing technique" and "below-the-umbilicus release technique", covering indications, acupoint location, and procedures. Clinical case examples are provided to enrich needle knife therapy guided by the theory of meridian tendons, offering insights for clinical and research work on AS.

Alzheimer's disease (AD) is a common neurodegenerative disorder among the elderly, and BuChE has emerged as a potential therapeutic target. In this study, we reported the development of compound 8e, a selective reversible BuChE inhibitor (eqBuChE IC₅₀ = 0.049 μmol/L, huBuChE IC₅₀ = 0.066 μmol/L), identified through extensive virtual screening and lead optimization. Compound 8e demonstrated favorable blood-brain barrier permeability, good drug-likeness property and pronounced neuroprotective efficacy. Additionally, 8e exhibited significant therapeutic effects in zebrafish AD models and scopolamine-induced cognitive impairments in mice. Further, 8e significantly improved cognitive function in APP/PS1 transgenic mice. Proteomics analysis demonstrated that 8e markedly elevated the expression levels of very low-density lipoprotein receptor (VLDLR), offering valuable insights into its potential modulation of the Reelin-mediated signaling pathway. Thus, compound 8e emerges as a novel and potent BuChE inhibitor for the treatment of AD, with significant implications for further exploration into its mechanisms of action and therapeutic applications.

AIM: To compare the efficacy of intravitreal injection of ranibizumab(IVR)and intravitreal injection of conbercept(IVC)in children with retinopathy of prematurity(ROP).METHODS: Retrospective study. A total of 1 100 eyes with ROP treated with intravitreal anti-VEGF at our hospital from January 2015 to June 2023 were included. According to the different therapeutic drugs, the children were divided into two groups: IVR group and IVC group. According to the degree of ROP, the patients were divided into three groups: aggressive ROP(A-ROP), Zone Ⅰ type 1 ROP and Zone Ⅱ type 1 ROP. The reactivation and retreatment between the two groups were compared after propensity score matching(PSM)analysis, and they were followed-up for at least 3 mo after surgery.RESULTS: In Zone Ⅱ type 1 ROP, there was a statistically significant difference in the rates of reactivation and retreatment between the IVR and IVC groups(P<0.05); however, in A-ROP and Zone I type 1 ROP, there were no statistically significant differences in the rates of reactivation and retreatment between the two groups(P>0.05). The risk of reactivation and retreatment of Zone I type 1 ROP was higher than the Zone II type 1 ROP. Furthermore, the use of drugs and corrected gestational age of first treatment were influencing factors of lesion recurrence and retreatment.CONCLUSION: There is a significant difference in the initial cure effect between the two drugs in Zone II type 1 ROP, with the reactivation and retreatment rates of the IVC group being much lower than those of the IVR group.

Objective: To analyze the disease burden and risk factors of colorectal cancer in Zhejiang Province from 1990 to 2019, so as to provide the basis for prevention and control of colorectal cancer. Methods: Based on data of 2019 Global Burden of Disease (GDB 2019), disease burden and risk factors of colorectal cancer in Zhejiang Province from 1990 to 2019 was assessed using years of life lost (YLL), years lived with disability (YLD), disability-adjusted life years (DALY). Results: In 2019, the YLL rate, YLD rate and DALY rate caused by colorectal cancer in Zhejiang Province were 496.15/105, 31.81/105 and 527.96/105, respectively. From 1990 to 2019, the YLL rate, YLD rate and DALY rate caused by colorectal cancer in Zhejiang Province increased by 114.90%, 482.60% and 123.38%, respectively, showing increasing trends (average annual percent change values were =2.663, 6.283 and 2.800, respectively,all P<0.05). From 1990 to 2019, the YLL rate, YLD rate and DALY rate in the age groups of 15 to 49 years, 50 to 69 years and 70 years and older showed increasing trends (all P<0.05). In 1990, the top ten risk factors for colorectal cancer in Zhejiang Province were diet low in calcium, diet low in milk, diet low in whole grains, smoking, alcohol use, low physical activity, high fasting plasma glucose, diet high in red meat, diet low in fiber and high body mass index. In 2019, the top ten risk factors for colorectal cancer in Zhejiang Province were diet low in milk, diet low in whole grains, diet low in calcium, alcohol use, diet high in red meat, high body mass index, high fasting plasma glucose, low physical activity, diet low in fiber and diet high in processed meat. Conclusions The disease burden of colorectal cancer in Zhejiang Province showed an upward trend from 1990 to 2019. The top ten risk factors for colorectal cancer remained between 1990 and 2019, while there was a slight change in ranking.

Objective Comprehensive mortality risk analyses and therapeutic assessment in real-world practice are beneficial to guide individual treatment in patients with Carbapenem-resistant Klebsiella pneumoniae bloodstream infections(CRKP-BSI).Methods Retrospective analysis of the clinical characteristics of 81 CRKP-BSI patients in our intensive care unit from July 2016 to June 2020,to indentify the risk factors of death and treatment effects of different antibiotic regimens.Results In 81 CRKP-BSI cases,the majority source were from abdominal and respiratory,accounting for 56.79%(46 cases)and 22.22%(18 cases),respectively.The 28-day mortality and hospitalization mortality of CRKP-BSI were 54.32%(44 cases)and 65.43%(53 cases).Multivariate regression analysis suggested that biliary tract disease before admission(P=0.026)and increased SOFA score at the onset of BSI(P=0.006)were independent risk factors for 28-day mortality.There was no statistically significant difference in 28-day mortality between the groups of antibiotic treatment based on tigecycline(44 cases)and polymyxin B(26 cases)[56.82%(25/44)vs.57.69%(15/26),P=0.943].Patients were evaluated based on their age(≤65 years vs.>65 years),gender,body mass index(≤25 kg/m2 vs.>25 kg/m2),and APACHEⅡ score(≤20 vs.>20),the use of renal replacement therapy and mechanical ventilation,there was no difference in the mortality among each subgroup.Conclusions Biliary tract disease before admission and SOFA score were independent risk factors for 28-day mortality.There was no significant difference outcomes between tigecycline-and polymyxin B-based therapy.

Objective:To evaluate the mid- and long-term outcomes of Dynesys hybrid surgery (in some segments act as a non-fusion device, in other segments act as an alternative of rigid fixation in combination with interbody fusion) in the treatment of multi-segmental lumbar degenerative disease (LDD).Methods:The data of 27 patients who received Dynesys hybrid surgery (hybrid group) for the treatment of LDD from May 2011 to September 2016 and completed the follow-up were retrospectively analyzed. Among them, there were 8 males and 19 females; their average age was 59.1±11.9 years (23-78 years). Main diagnosis: 13 cases of lumbar spinal stenosis, 14 cases of lumbar disc herniation; 4 cases of combined lumbar dynamic position instability, 7 cases of combined lumbar spondylolisthesis. There were 15 cases of two-segment disease, 11 cases of three-segment disease, and 1 case of four-segment disease. Segments distribution: 9 cases of L 3-L 5, 6 cases of L 4-S 1, 7 cases of L 3-S 1, 4 cases of L 2-L 5, and 1 case of L 2-S 1. Midline incision was used to exposure, followed by bilateral pedicle screws implantation, and interbody fusion cage with bone grafting were performed at the fusion level. Twenty-seven patients who underwent TLIF+rigid internal fixation during the same period were included as the control group. Clinical outcomes were measured by visual analog scale (VAS) for low back pain and leg pain, and Oswestry disability index (ODI). Radiological outcomes included fusion rate, intervertebral disc height (DH) of surgical segments and the proximal adjacent segment, range of motion (ROM) of non-fusion segments and the proximal adjacent segment. At the same time, the occurrence of complications was observed. Results:Patients of Hybrid group and control group were followed up for an average of 83.8±20.9 months (48-112 months) and 87.3±16.2 months (53-114 months), respectively. Baseline data of the two groups (average follow-up time, age, gender, surgical level, diagnosis) showed no significant difference. The operation time (183.0±27.8 min) and intraoperative blood loss (301.9±178.9 ml) in the hybrid group were significantly lower than those in the control group (operation time t=2.337, P=0.023; blood loss t=2.706, P=0.01). At the final follow-up, the VAS scores of low back pain and leg pain (low back pain t=12.164, P<0.001; leg pain t=20.603, P<0.001), as well as ODI were significantly improved ( t=22.827, P<0.001). A total of 32 segments received TLIF+Dynesys stabilization and 35 segments received Dynesys non-fusion stabilization in the hybrid group, with 28 segments (87.5%) achieved solid fusion at 1-year follow-up. There were 67 fusion segments in the control group, and the fusion rate at 1-year follow-up was 85.1%. DH of non-fusion segments were lower than that before surgery with statistical significance at final follow-up ( t=2.647, P=0.012), while DH of the fusion segments in the hybrid group and the surgical segments in the control group increased compared with that before surgery at the final follow-up. A certain degree of ROM (2.4°±1.5°) was retained of the non-fusion segments at the final follow-up; the ROM of proximal adjacent segments of non-fused segments was significantly smaller than that of proximal adjacent segments of fused segments ( t=2.126, P=0.044). In the hybrid group, screw loosening occurred in 4 patients (8 screws) and adjacent segment degeneration (ASD) occurred in 5 patients. In the control group, screw loosening occurred in 3 patients (6 screws), while ASD occurred in 8 patients. No screw fracture was observed during the follow-up period and no patients received reoperation. Conclusion:Hybrid surgery of Dynesys stabilization combined with interbody fusion is a safe and effective method for the treatment of multi-segmental LDD. Compared with multi-segmental fusion, this lumbar hybrid surgery has the advantages of less trauma and retaining partial segmental ROM.

Objective:To evaluate the early predictive value of serum procalcitonin (PCT) , C-reactive protein (CRP) , and white blood cell count (WBC) levels for pancreatic fistula after pancreaticoduodenectomy (PD) .Methods:Data of 93 patients undergoing PD in Department of Pancreatic Surgery at the First Affiliated Hospital of Xinjiang Medical University from Jan. 2017 to Nov. 2019 were retrospectively analyzed. The general information of patients before surgery and postoperative pancreatic fistula were recorded. The levels of serum PCT, CRP, and WBC before surgery and 1st, 3rd, and 5th days after operation were recorded. Patients were divided into pancreatic fistula group (63 cases) and non-pancreatic fistula group (30 cases) . The preoperative data were compared between the two groups. Box plot and the receiver operating characteristic curve (ROC) were drawn. The area under the ROC curve (AUC) was calculated. The sensitivity and specificity of PCT, CRP, and WBC levels in predicting pancreatic fistula alone and jointly were calculated.Results:There were no statistically significant differences in the age, gender, presence or absence of diabetes, total bilirubin, preoperative albumin, surgical time, or intraoperative bleeding in the general information of the pancreatic fistula group and the non-pancreatic fistula group. The difference in index (BMI) was statistically significant. The value of PCT, CRP, and WBC before operation and the value of PCT on the first day after operation were not statistically significant between the two groups ( P=0.424, 0.819, 0.484, and 0.072, respectively) . The PCT values on the 3rd and 5th days after surgery, the values of CRP and WBC on the 1st, 3rd, and 5th days after surgery were all statistically significant (all P values were<0.05) . The area under the ROC curve was jointly predicted by the three at the 3rd and 5th days after operation (AUC=0.792, 0.812) , and the sensitivity (62.9%, 71.4%) and specificity (83.3%, 80%) were better than the three alone. Conclusion:PCT, CRP, and WBC values on the 1st, 3rd, and 5th days after surgery alone have certain limitations in predicting pancreatic fistula, and the combined prediction of the three is more valuable.

Objective: To understand the prevalence and disease burden of major chronic diseases in the elderly in China and provide scientific basis for the prevention and control of chronic diseases and for the rational allocation of health resources. Methods: We analyzed the prevalence of chronic diseases in residents aged ≥60 years in China by using national and provincial surveillance data of chronic diseases and related risk factors in China. We conducted the analysis on the burden of chronic diseases in the elderly in China by using the data of global burden of disease. Results: The prevalence rates of hypertension, diabetes and hypercholesterolemia were 58.3%, 19.4% and 10.5% respectively in residents aged ≥60 years in China. Up to 75.8% of the residents aged ≥60 years had at least one chronic disease. The prevalence rate was higher in women than in men, higher in urban area than in rural area. With the increase of age, the prevalence rate of chronic diseases also increased. The top three chronic diseases with heavy disease burden in residents aged ≥70 years were stroke, myocardial infarction, cancer and chronic obstructive pulmonary disease. Conclusion The prevalence of major chronic diseases in the elderly is high with three quarters of the elderly suffering from at least one chronic disease, and the burden of chronic diseases is increasing.

Objective To summarize the CT characteristics of tumor deposition adjacent to colorectal cancer (CRC),and provide the evidences for differential diagnosis.Methods The retrospective cross-sectional study was conducted.The clinicopathological data of 26 CRC patients who were admitted to the Wuxi Second People's Hospital of Nanjing Medical University from May 2015 to April 2017 were collected.Patients underwent preoperative multi-slice spiral CT scan and double-phase enhanced scan,and then received open surgery.Observation indicators:(1) characteristics of multi-slice spiral CT scan;(2) differential comparisons;(3) follow-up.Follow-up using telephone interview was performed to detect patients' prognosis once every 3 months up to May 2017.Measurement data with normal distribution were represented as (x)±s.Comparisons between groups and among groups were respectively analyzed using the t test and the one-way ANOVA.Pairwise comparison was done using the SNK method.Results (1) Characteristics of multi-slice spiral CT scan:of 26 patients,17 underwent double contrast enhanced scans of chest,abdomen and pelvic and 9 underwent double contrast scans of abdomen and pelvic.Primary tumors of 18 and 8 patients respectively located in the colon and rectum.Forty-one tumor deposits of 26 patients were collected,with number of tumor deposits of 1.6±0.9 per case,and number of tumor deposits ＜ 3 and ≥3 respectively were found in 20 and 6 patients.Tumor deposits were often isolated in the fat spaces around the rectum or colon and unconnected with the surrounding primary tumor or lymph node.Distance to the center of primary tumor was (2.6±l.0)cm (range,0.2-5.0 cm),the distance ＜2.6 cm and ≥2.6 cm were respectively detected in 22 and 19 patients.Thirty-three tumors showed signs of lobulation,22 showed signs of burr and 7 showed liquefaction necrosis,and there was a combination of multiple imaging characteristics in the same tumor deposit.The maximum width,minimum width,maximum diameter,plain scan value of CT,CT enhancement values in the arterial phase and venous phase in 41 tumor deposits were respectively (1.15 ± 0.60)cm,(1.11±0.44)cm,(1.13±0.49)cm,(27±13)HU,(28±14)HU and (49±19)HU.Of 41 tumor deposits,34 demonstrated homogeneous density in the plain scan,and obviously enhancement in early enhanced scan,with homogeneous enhancement;7 demonstrated heterogeneous density in the plain scan,with internal liquefaction necrosis,and enhanced scans showed no enhancement in the areas of necrosis and obviously early enhancement in the areas of non-necrosis.(2) Differential comparisons:26 patients underwent open surgery,including 8 with right hemectomy,2 with transverse colon resection,4 with left semicolon resection,2 with simple sigmoid resection,2 with abdominoperineal resection of rectal cancer and 8 with low anterior rectal resection,and all patients received postoperatively individualized treatment.Fifty-two lymph nodes with distance to center of primary tumor ＜ 5.0 cm that were confirmed by pathological examination were collected,including 19 metastatic lymph nodes.Of 41 tumor deposits,33 were irregular,and 8 were regular and round-like or oval-like shape.Of 19 metastatic lymph nodes,16 were regularly round-like shape,1 showed irregular shape and edge blur,and 2 were irregular with a mutual integration.The maximum width,minimum width and maximum diameter of 19 metastatic lymph nodes were respectively (1.09± 0.33) cm,(1.01 ± 0.23) cm and (1.05 ± 0.20) cm,with statistically significant differences in the above indicators between metastatic lymph nodes and tumor deposits (t =5.48,4.80,7.75,P＜0.05).The plain scan value of CT,CT enhancement values in the arterial phase and venous phase were respectively (12±7) HU,(18± 12) HU,(42± 15) HU in 19 metastatic lymph nodes and (33±6) HU,(31 ±15) HU,(53± 14)HU in 26 primary tumors,showing statistically significant differences in the plain scan value of CT and CT enhancement values in the arterial phase among tumor deposits,metastatic lymph nodes and primary tumors (F=24.43,4.46,P＜0.05),and no statistically significant difference in CT enhancement value in the venous phase (F=2.41,P＞0.05).There were statistically significant differences in the plain scan value of CT and CT enhancement values in the arterial phase between tumor deposits and metastatic lymph nodes (q =5.48,2.50,P＜0.05) and between metastatic lymph nodes and primary tumors (q =6.82,2.84,P＜0.05),and no statistically significant difference between tumor deposits and primary tumors (q =2.15,0.65,P＞0.05).Of 19 metastatic lymph nodes,11 demonstrated homogeneous density in plain scan,with a lower density compared with tumor deposits and primary tumors,and relatively homogeneous enhancement in the arterial phase of enhanced scan;8 demonstrated heterogeneous density with internal liquefaction necrosis,and ring-shaped enhancement in enhanced scan with no enhancement in the areas of necrosis.The density and enhancement range in the arterial phase and venous phase of tumor deposits were similar to primary tumors.(3) Follow-up:24 patients were followed up for 1-25 months,with a follow-up rate of 92.3％(24/26) and a median time of 17 months.Of 24 patients,2 were dead,and survival time were respectively 9 months and 21 months;22 had good survival.Conclusions Multislice spiral CT examination of tumor deposits demonstrates larger and irregular shape,with the signs of lobulation and burr,and the density in plain scan is similar to the primary tumor,with obviously enhancement in early enhanced scan.The metastatic lymph nodes are mostly round-like shape,diameter is smaller than that of tumor deposits,density in the plain scan and CT enhancement values in the arterial phase are lower than that of tumor deposits.
