BACKGROUND: Approximately 40% of individuals with diabetes worldwide are at risk of developing diabetic kidney disease (DKD), which is not only the leading cause of kidney failure, but also significantly increases the risk of cardiovascular disease, causing significant societal health and financial burdens. This study aimed to describe the burden of DKD and explore its cross-country epidemiological status, predict development trends, and assess its risk factors and sociodemographic transitions. METHODS: Based on the Global Burden of Diseases (GBD) Study 2021, data on DKD due to type 1 diabetes (DKD-T1DM) and type 2 diabetes (DKD-T2DM) were analyzed by sex, age, year, and location. Numbers and age-standardized rates were used to compare the disease burden between DKD-T1DM and DKD-T2DM among locations. Decomposition analysis was used to assess the potential drivers. Locally weighted scatter plot smoothing and Frontier analysis were used to estimate sociodemographic transitions of DKD disability-adjusted life years (DALYs). RESULTS: The DALYs due to DKD increased markedly from 1990 to 2021, with a 74.0% (from 2,227,518 to 3,875,628) and 173.6% (from 4,122,919 to 11,278,935) increase for DKD-T1DM and DKD-T2DM, respectively. In 2030, the estimated DALYs for DKD-T1DM surpassed 4.4 million, with that of DKD-T2DM exceeding 14.6 million. Notably, middle-sociodemographic index (SDI) quintile was responsible for the most significant DALYs. Decomposition analysis revealed that population growth and aging were major drivers for the increased DKD DALYs in most regions. Interestingly, the most pronounced effect of positive DALYs change from 1990 to 2021 was presented in high-SDI quintile, while in low-SDI quintile, DALYs for DKD-T1DM and DKD-T2DM presented a decreasing trend over the past years. Frontiers analysis revealed that there was a negative association between SDI quintiles and age-standardized DALY rates (ASDRs) in DKD-T1DM and DKD-T2DM. Countries with middle-SDI shouldered disproportionately high DKD burden. Kidney dysfunction (nearly 100.0% for DKD-T1DM and DKD-T2DM), high fasting plasma glucose (70.8% for DKD-T1DM and 87.4% for DKD-T2DM), and non-optimal temperatures (low and high, 5.0% for DKD-T1DM and 5.1% for DKD-T2DM) were common risk factors for age-standardized DALYs in T1DM-DKD and T2DM-DKD. There were other specific risk factors for DKD-T2DM such as high body mass index (38.2%), high systolic blood pressure (10.2%), dietary risks (17.8%), low physical activity (6.2%), lead exposure (1.2%), and other environmental risks. CONCLUSIONS DKD markedly increased and varied significantly across regions, contributing to a substantial disease burden, especially in middle-SDI countries. The rise in DKD is primarily driven by population growth, aging, and key risk factors such as high fasting plasma glucose and kidney dysfunction, with projections suggesting continued escalation of the burden by 2030.

OBJECTIVE: To explore the methods, fixation points, and effectiveness of staged therapy using external fixation frame in treatment of infectious nonunion near knee joint. METHODS: A retrospective analysis was conducted on the clinical data of 60 patients with infectious nonunion near knee joint, who underwent staged therapy using external fixation frame between June 2021 and June 2024 and were followed up. There were 48 males and 12 females with an average age of 47.9 years (range, 16-70 years). The disease duration ranged from 9 months to 20 years, with a median of 14 months. Among them, 21 cases of infectious nonunion located in the distal femur, 36 cases in the proximal tibia, and 3 cases in the patella; 12 cases exhibited segmental bone defects (≥4 cm), while 48 cases presented with localized bone defects (<4 cm). Osteomyelitis was classified using the Cierny-Mader system, with 3 cases classified as type Ⅰ, 6 cases as type Ⅱ, 35 cases as type Ⅲ, and 16 cases as type Ⅳ. Preoperative C-reactive protein levels ranged from 15.1 to 55.8 mg/L (mean, 36.4 mg/L). The erythrocyte sedimentation rate was 35-80 mm/1 h (mean, 56.9 mm/1 h). The Hospital for Special Surgery (HSS) score for knee joint was 69.3±17.7 and the range of motion was (70.61±40.60)°. After debridement and placement of antibiotic carriers at the first-stage operation, unilateral orbital frames ( n=14), combined frames ( n=27), or Ilizarov frames ( n=19) were used for cross joint fixation ( n=9) or joint preservation fixation ( n=51). After 6-8 weeks of infection control, the bone grafting or bone transport was performed at the second-stage operation based on the type of bone defect, with internal fixation employed as an adjunct if necessary. After operation, the infection control and fracture healing were observed and the bone healing time was recorded. The knee joint function was assessed using the HSS score, and the knee joint range of motion was measured as well as the angle of motion loss. Patients were grouped according to the site of nonunion, type of external fixation frame, and fixation method. The bone healing time, change value of HSS score, and knee joint range of motion loss (difference between pre- and post-operation) were compared between groups. RESULTS: All infection markers returned to the normal range within 6 weeks after the first-stage operation. All patients were followed up 12-48 months (mean, 22.0 months) after the second-stage operation. There were 5 cases of needle tract infection during the external fixation period, and 3 cases of infection recurrence after the second-stage operation, all of which were cured after symptomatic treatment. The bone healing time was 6-18 months (mean, 11.0 months). At last follow-up, the HSS score was 88.5±7.9 and the range of motion was (61.84±40.59)°, with significant differences compared to preoperative values ( P<0.05); the knee joint range of motion loss was (8.77±11.07)°. The bone healing time was significantly longer in the distal femur group than in the proximal tibia group ( P<0.05), and in the unilateral orbital frames group than in the Ilizarov frames group and the combined frames group ( P<0.05). The angle of motion loss was significantly larger in the Ilizarov frames group than in the unilateral orbital frames group and the combined frames group ( P<0.05). The change value of HSS score was significantly higher in the cross joint fixation group than in the joint preservation fixation group ( P<0.05). CONCLUSION During the first-stage operation, debridement is performed and antibiotic carriers are placed to control infection. External fixation frames are then precisely positioned based on the distance between the lesion and the joint surface, avoiding the infected wound while ensuring mechanical balance. During the second-stage operation, bone grafting options are selected according to the extent of bone defects to enhance the bone union. Postoperative early functional exercises of the knee joint are permitted to improve joint function.

OBJECTIVE: To explore the effectiveness of primary interventional revascularization combined with secondary perforator composite flap in the treatment of peripheral arterial disease (PAD) accompanied by soft tissue defects around the ankle. METHODS: Between January 2022 and January 2025, 12 patients with PAD and soft tissue defects around the ankle were admitted. Among them, there were 9 males and 3 females; their ages ranged from 52 to 82 years, with an average of 68.9 years. The causes of injury included 4 cases of traffic accident, 5 cases of falls, 1 case of falling from height, 1 case of foreign body puncture injury, and 1 case of electric shock injury. The infection duration ranged from 1 month to 35 years, with a median duration of 3.5 months. The wound size ranged from 5.5 cm×3.0 cm to 15.0 cm×9.0 cm. The ankle-brachial index (ABI) was 0.32±0.12. The visual analogue scale (VAS) score for pain was 3.3±0.5. Preoperative vascular stenosis assessment was performed in all patients, with primary intervention to dredge large and medium-sized arteries, followed by secondary repair of the wound using a perforator composite flap. The flap size ranged from 6.5 cm×4.0 cm to 16.0 cm×10.0 cm. The donor sites were sutured directly or repaired with skin grafts. After two stages of treatment, the effectiveness was evaluated by measuring ABI, observing flap survival and wound healing, assessing VAS scores, and American Orthopedic Foot and Ankle Society (AOFAS) scores. RESULTS: All 12 cases completed two stages of treatment; all patients were followed up after the second-stage treatment, with a follow-up period ranging from 7 to 28 months, with an average of 16.8 months. After the first-stage treatment, the skin temperature around the ankle was significantly higher than that before treatment, and the ABI increased to 0.71±0.07, with a significant difference ( t=9.918, P<0.001). After the second-stage treatment, the blisters on the distal end of the skin flap occurred in 3 cases. The flaps survived and the wounds healed, with a healing time ranging from 10 to 14 days (mean, 11.8 days). The incisions at the donor site healed by first intention, and the skin grafts survived. The VAS score was 0.5±0.5 at 3 weeks, which was significantly lower than that before treatment ( t=13.675, P<0.001). No infection recurrence occurred during follow-up. At 6 months after the second-stage treatment, the AOFAS score of the ankle joint ranged from 92 to 97, with an average of 94.7, all reaching excellent. CONCLUSION Interventional revascularization combined with perforator composite flap for staged treatment of PAD with ankle soft tissue defects can obtain good effectiveness, by unclogging the main blood vessels, improving lower limb blood supply, and improving the survival rate of the skin flap.

OBJECTIVE To systematically evaluate the effects of C3435T polymorphism in ABCB1 gene on lipid-lowering efficacy of statins. METHODS Retrieved from PubMed， Web of Science， the Cochrane Library， CNKI and VIP， the cohort studies on the use of statins were collected from the inception to November 1， 2023. After literature screening， data extraction and quality evaluation， meta-analysis was performed by using RevMan 5.4 software. RESULTS A total of 11 literature involving 1 575 patients were included. The results showed that under the dominant genetic model， the reduction of low-density lipoprotein cholesterol （LDL-C） [MD＝－1.87， 95%CI （－3.62， －0.13）， P＝0.04]， total cholesterol （TC） [MD＝－1.42， 95%CI （－2.80， －0.04）， P＝0.04] in patients with CT+TT genotype was significantly higher than CC genotype. There was no significant difference in the increase of high-density lipoprotein cholesterol （HDL-C） [MD＝－0.65， 95%CI （－2.48， 1.18）， P＝0.49] or the decrease of triglyceride （TG） [MD＝－0.05， 95%CI （－2.94， 2.84）， P＝0.97] between patients with CT+TT genotype and CC genotype. Under the recessive genetic model， the reduction of TC [MD＝2.26， 95%CI （0.97， 3.56）， P＝0.000 6] and the increase of HDL-C [MD＝2.38， 95%CI （0.42， 4.35）， P＝0.02] in patients with TT genotype were significantly higher than CC+ CT genotype. There was no significant difference in the reduction of LDL-C [MD＝1.53， 95%CI （－0.10， 3.15）， P＝0.07] or TG [MD＝0.06， 95%CI （－2.98， 3.10）， P＝0.97] between CC+CT genotype and TT genotype. Under the additive genetic model， the reduction of TC [MD＝2.98， 95%CI （1.27， 4.69）， P＝0.000 6] and LDL-C [MD＝2.84， 95%CI （0.67， 5.01）， P＝0.01] in patients with TT genotype were significantly higher than CC genotype. There was no significant difference in the increase of HDL-C [MD＝2.40， 95%CI （－0.17， 4.97）， P＝0.07] or the decrease of TG [MD＝0.97， 95%CI 　　 （－2.93， 4.87）， P＝0.63] between patients with TT genotype and CC genotype. CONCLUSIONS The reduction of LDL-C and TC in patients with dyslipidemia treated with statins may be related to the heterozygous and homozygous mutation of C3435T in ABCB1 gene， and the reduction of LDL-C and TC in patients with CT or TT genotype is more obvious， compared with patients with CC genotype. The elevation of HDL-C may be related to homozygous mutation， and the effect of HDL-C elevation may be more obvious in patients with TT genotype， compared with CC+CT genotype. However， the change of TG may not be related to the C3435T polymorphism in ABCB1 gene.

In September 8 th, 2021, a male patient (aged 18 years) with severe destructive injuries of high-voltage electric burns in the head, face, and neck was admitted to General Hospital of Taiyuan Iron Steel (Group) Co., Ltd. Based on the economic theory of flaps, the flap donor site and transplantation method were optimized and evaluated before surgery, and then debridement of head, face, and neck wounds+removal of necrotic skull+free transplantation of super large latissimus dorsi myocutaneous flap+thin intermediate thickness skin graft transplantation from the left thigh was performed. The extra large flap donor site wound was sutured directly. This surgery reduced the adverse consequences of the flap donor site on the premise of ensure of repair effect. After operation, the patient's condition was stable, the flap and skin graft survived well, the repair effect of wound was well, the scar in the flap donor area was relatively mild, and the upper limb had no dysfunction.

Objective To analyze the current status, hotspots and difficulties of research on colorectal serrated polyps using CiteSpace software. Methods Chinese literature was searched in the China National Knowledge Infrastructure (CNKI) database from its inception to March 6, 2023. English literature was searched in the Medline database from its inception to March 21, 2023. CiteSpace software was used to create visual maps and conduct visual analysis of publication volume, institutions and keywords. Results A total of 198 Chinese articles were included in this study, with Beijing Military General Hospital publishing the most articles. "Pathology" appeared with the highest frequency, and clinic and endoscopic characteristics had been research hotspots in recent years. This study included 1 257 English articles. The keyword "colorectal cancer" appeared with the highest frequency, adenoma detection, colon cancer screening, computer-aided detection, adenoma missed diagnosis rate and artificial intelligence had been research hotspots in recent years.

Purpose: Inflammatory myofibroblastic tumor (IMT) is a rare mesenchymal malignancy that occurs primarily in children and adolescents. The clinical and pathological features of IMT in adult patients are not well understood. Materials and Methods: We retrospectively searched for records of adult patients with IMT at Fudan University Shanghai Cancer Center from 2006 to 2021. Clinicopathological data, treatments, and outcomes were collected and analyzed. Results: Thirty adult patients with IMT, mostly women (60.0%), were included. The median age of the patients was 38 (21-77). The most common primary site was abdominopelvic region (53.3%), followed by lungs (20.0%). Seven patients had an abdominal epithelioid inflammatory myofibroblast sarcoma (EIMS). The positivity rate of anaplastic lymphoma kinase (ALK) was 81.5% (22/27). Sixteen patients with advanced ALK-positive disease received crizotinib, with an objective response rate (ORR) of 81.3% and a disease control rate of 87.5%. The median progression-free survival was 20.8 months. EIMS was associated with more aggressive behavior; however, the prognosis was similar to that of non-EIMS patients after treatment with an ALK inhibitor. At a median follow-up time of 30 months (95% confidence interval [CI], 13.6 to 46.4), the 5-year overall survival was 77% (95% CI, 66 to 88) in all patients. Conclusion Adult IMTs appeared more aggressive, with a higher incidence of recurrence and metastases, and patients with EIMS had more aggressive cases. Treatment with ALK inhibitors resulted in a high ORR and a durable response, which suggested that ALK inhibitors could be used as a first-line treatment option in adult patients with ALK-positive advanced IMT.

Objective: To understand the status of pinworm infection in rural children aged 3-9 years in Anhui Province, and to provide scientific basis for the prevention and control strategy of pinworm disease. Methods: According to the National Surveillance Program of Liver Fluke Disease and Soil Transmitted Nematodiasis(Trial), no less than 10% counties(cities and districts) in Anhui Province were selected as mobile surveillance sites every year. Each surveillance site was divided into 5 areas on the basis of geographical location(east, west, south, north and middle), from each of the areas, one administrative village was selected from one township(town, community) for conducting surveillance. Children at age 3-9 years from each site were examined for pinworm infection with the modified Kato-Katz thick smear method and the adhesive cellophane tape perianal swab method. Chi square test was used to compare the infection rate. Results: From 2017 to 2021, the 5 year average infection rate of pinworm in rural Anhui was 1.34%(128/9 557), and there was no significant difference in the infection rate over the years( P >0.05). The detection rates of the modified Kato-Katz thick smear method and the adhesive cellophane tape perianal swab method were 0.28% and 1.23%, respectively, the difference was statistically significant( χ 2=72.97, P <0.01). In different regions, the 5 year average infection rate of Fuyang City was the highest(4.27%), and the rate of each city was positively correlated with the number of local resident population( r =0.54, P <0.05). There was no significant sex difference in the 5 year average infection rates( P >0.05). The 5 year average infection rate of children aged 3 to 9 years in rural areas were 0.62%, 1.10%, 1.44%, 1.57%, 0.94%, 2.09% and 1.57%, respectively, showed an increasing trend with the increase of age( χ 2=14.41, χ 2 trend =6.70, P <0.05). There was no significant difference in the average infection rate between scattered children and collectively living children( P >0.05). Conclusion From 2017 to 2021, the infection rate of pinworm among children in rural Anhui province remains at a low level. In the future, health education and monitoring should be strengthened.

Objective:To analyze the mechanism of Jindan Tablets, Xiaoyan Lidan Tablets and ursodeoxycholic acid in the treatment of gallstone and cholecystitis based on network pharmacology; To conduct a comparative analysis.Methods:The chemical components of Jindan Tablets, Xiaoyan Lidan Tablets and ursodeoxycholic acid and their drug targets were collected from Traditional Chinese Medicine Database and Analysis Platform (TCMSP). DAVID 6.8 database was used to search for the associated diseases of the drug targets. The disease targets of gallstone and cholecystitis were collected from GeneCards and other databases. The protein-protein interactions network was established based on the intersecting targets of three drugs and two diseases. KEGG enrichment analysis was performed based on the DAVID 6.8 database. Cytoscape 3.7.1 software was used to construct a complex network and topology analysis of component- target- disease between three drugs and diseases.Results:222 chemical components and 3 133 drug targets were collected for Jindan Tablets. 104 chemical components and 1 425 action targets were collected for Xiaoyan Lidan Tablets. 1 chemical component and 119 action targets were collected for ursodeoxycholic acid. The three drugs were associated with 31 diseases. 1 382 disease targets for gallstones and cholecystitis were collected. There were 237, 163 and 33 targets for gallstones and cholecystitis in the three drugs, of which 17 were shared by the three drugs and 20 were shared by Jindan Tablets and Xiaoyan Lidan Tablets. Based on the DAVID database, 113, 74 and 10 significant KEGG enrichment pathways were obtained for the three drugs respectively.Conclusions:The three drugs shared many targets and pathways in the treatment of gallstones and cholecystitis, which all had the function of regulating metabolism and inhibiting inflammatory response, while participating in apoptosis, oxidative stress and cancer pathology process. However, they had their own special effects, with Jindan Tablets favoring involving in the cancer process and inhibition of inflammation, and promoting angiogenesis. Xiaoyan Lidan Tablets and ursodeoxycholic acid focused on regulating cholesterol metabolism, and Xiaoyan Lidan Tablets also regulated steroid metabolism and inhibit inflammation, while ursodeoxycholic acid regulated bile acid metabolism.

Objective To observe the effect of pre-hospital and intra-hospital collaborative ther-apeutic model in the treatment of patients with acute cerebral infarction.Methods A total of 67 pa-tients with acute cerebral infarction were selected as the research objects,and they were divided into observation group(n=37)and control group(n=30)according to the therapeutic model.The con-trol group was conducted with the traditional therapeutic model,while the observation group was con-ducted with the pre-hospital and intra-hospital collaborative therapeutic model.The time efficiency of intravenous thrombolysis,early recovery of nerve function and oxidative stress indexes were compared between the two groups.Results There was no significant difference in the time from onset to visit between the two groups(P＞0.05);the time from seeing a doctor to thrombolysis and the time from seeing a doctor to signing the informed consent for intravenous thrombolysis in the observation group were significantly shorter than those in the control group(P＜0.05).On the hospital admission,there was no significant difference in the National Institutes of Health Stroke Scale(NIHSS)score be-tween the two groups(P＞0.05);at the time points of 7 days after admission and 90 days after thrombolysis,the NIHSS scores of patients in the observation group were significantly lower than that in the control group(P＜0.05).There were no significant differences in the levels of serum glutathione peroxidase(GSH-Px)and malonaldehyde(MDA)between the two groups(P＞0.05);the level of serum superoxide dismutase(SOD)in the observation group was significantly higher than that in the control group(P＜0.05).One patient died in the control group,with a mortality rate of 3.33％;no patient died in the observation group.Conclusion Pre-hospital and intra-hospital collaborative therapeutic model can effectively improve the time efficiency of intravenous thrombolysis for patients with acute cerebral infarction,alleviate the neurological damage,and reduce degree of oxidative stress reaction and death risk.
