Objective To explore the application effect of negative pressure sealing drainage combined with active factor dressing and flap transfer in Gustilo Ⅲ type tibiofibular fractures.Methods From March 2019 to March 2022,92 patients with Gustilo type Ⅲ tibiofibular fracture admitted to the Department of Orthopaedics of the Third People's Hospital of Zhangjiagang City were randomly divided into the experimental group(internal and external fixation+flap transfer+negative pressure sealing drainage+active factor dressing,n=46)and the control group(internal and external fixation+flap transfer+conventional dressing change+active factor dressing,n=46),and the clinical indexes,clinical efficacy,ankle joint function,lower limb function and complications were compared.Result The hospital stay time(25.32±8.36)d,the flap healing time(9.69±1.24)d,the fracture healing time(8.24±1.84)month and the wound healing time(14.24±3.84)d of the experimental group were shorter than those of the control group(43.44±11.84)d,(11.53±2.07)d and(9.12±2.50)month,(50.11±5.12)d(P＜0.05).The total effective rate of the experimental group(93.48％,43 cases/46 cases)was higher than that of the control group(71.74％,33 cases/46 cases,P＜0.05).The ankle pain scores of both groups after treatment were lower than before treatment,and the experimental group was lower than the control group,and the scores of ankle function and stability,the scores of American Association of Foot and Ankle Surgery(AOFAS)and the knee joint score of American Hospital for Special Surgery(HSS)after treatment were higher in both groups than before treatment,and the experimental group was higher than the control group(P＜0.05).The total complication rate of the experimental group(4.34％,2 cases/46 cases)was lower than that of the control group(17.39％,8 cases/46 cases,P＜0.05).Conclusion The application of negative pressure closed drainage combined with active factor dressing in Gustilo typeⅢ tibia and fibula fracture is effective,can promote postoperative wound recovery,improve ankle and lower limb function,and the incidence of complications is low.

Objective To evaluate the clinical application of early total care (ETC) for polytrauma patients combined with thoracolumbar fractures.Methods A retrospective case control study was conducted to analyze the clinical data of 137 polytrauma patients combined with thoracolumbar fractures admitted to the First Affiliated Hospital of Soochow University and the Third People's Hospital of Zhang,jiagang from January 2012 to October 2015.There were 90 males and 47 females,aged 26-69 years,with an average age of 48.2 years.The patients were divided into ETC group (n =59) and TMC group (n =78).In the ETC group,physicians from different departments evaluated the patients and developed individualized therapeutic regimens to allow the patients to undergo surgery at early stage after injury.The TMC group preferentially stabilized the patient's condition or transferred the patients to specialist treatment,and then the surgery was performed electively after the condition of the patient was stable.The ISS of the ETC group was (22.15 ± 9.28)points,and that of the TMC group was (23.37 ± 10.74) points.All patients underwent conventional posterior pedicle screw internal fixation.For patients with burst fracture and nerve injury,posterior spinal canal decompression was performed.The thoracolumbar injury classification and severity score (TLICS),spinal load sharing classification (LSC),preoperative and postoperative Glasgow coma score (GCS),Frankel classification,hospitalization time and postoperative complications were compared between the two groups.Results The TLICS scores of ETC group were significantly lower than those of TMC group (P ＜ 0.05) while the LSC scores showed no significant differences between the two groups (P ＞ 0.05).ETC group had shorter hospitalization time [(11.8 ± 3.7)days ∶ (17.5 ±4.5)days] and lower pressure ulcer incidence [(5％ ∶ 21％)] than the TMC group (P ＜ 0.05 or 0.01),but the former had significantly higher wound infection rate [(17％ ∶ 15％)] (P ＜ 0.05).There was no significant difference in pulmonary infection and deep venous thrombosis incidence between the two groups (P ＞ 0.05).No significant differences were found in the preoperative GCS scores between the two group (P ＞ 0.05) while the postoperative GCS scores of TMC group were higher than those of ETC group (P ＜ 0.01).Postoperative GCS scores in both groups were significantly higher than their preoperative GCS (P ＜ 0.05).The results of postoperative Frankel classification in the ETC group were as follows:Grade A in one patient,Grade B in one,Grade C in three,Grade D in four and Grade E in two patients,with an improvement rate of 82％.The results of postoperative Frankel classification in the TMC group were as follows:Grade A in three patients,Grade B in three,Grade C in three,Grade D in four and Grade E in four,with an improvement rate of 65％.Conclusions For polytrauma patients combined with thoracolumbar fractures,ETC can shorten hospitalization time,reduce the pressure ulcer incidence,and better facilitate the recovery of nerve function,yet with higher wound infection risk compared with TMC.TMC was preferred subjectively for patients with unstable thoracolumbar fractures and high TLICS.

Objective:To investigate the mechanism by which baicalein alleviates osteoarthritis by regulating Sirtuin (Sirt) to inhibit the senescence of fibroblast-like synoviocytes (FLS).Methods:FLS were extracted from synovium of non-osteoarthritis patients (3 patients) and osteoarthritis patients (3 patients), and assessed the senescence of FLS in osteoarthritis patients by Western blot, β-galactosidase staining and immunofluorescence, and examined the changing levels of Sirt family proteins and mRNAs in FLS. The relative expression level of Sirt1 in FLS was knocked down by transfection with Sirt1 siRNA, and the antioxidative capacity and senescence degree of FLS were analyzed. Chondrocytes were co-cultured with FLS and functional changes in chondrocytes were detected by Western blot. After inducing FLS senescence with bleomycin (BLM), different concentrations of baicalein were administered to detect the expression levels of Sirt1, p16, and p21 proteins and intracellular reactive oxygen species (ROS). The expression level of Sirt1 in FLS was knocked down, and BLM and baicalein treatments were applied. The relative expression levels of Sirt1 and ROS were detected using Western blot and ROS assays. After BLM-induced FLS senescence, baicalein and Compound C were added. The relative expression levels of phosphorylated AMP-activated protein kinase (pAMPK), nuclear factor erythroid 2-related factor 2 (NRF2), p16, p21, and ROS were detected by Western blot and ROS assays.Results:The relative expression of p16 and p21 in FLS in the osteoarthritic group were 3.66±0.38 and 3.55±0.34, which were higher than those in non-osteoarthritis group 1.00±0.07 and 1.00±0.09 ( t=11.860, P<0.001; t=12.520, P<0.001). The relative expression levels of Sirt1 and Sirt6 in FLS in the osteoarthritis group were 0.30±0.04 and 0.16±0.01, which were smaller than those in the non-osteoarthritis group 1.00 ± 0.03 and 1.00±0.04 ( t=23.840, P<0.001; t=34.130, P<0.001). After baicalein treatment, the relative expression of ROS was 2.58±0.28, 1.65±0.14 and 1.00±0.24 in the BLM, BLM+Bai and control groups, respectively, with statistically significant differences between the groups ( F=35.700, P<0.001), which was greater in the BLM and BLM+Bai than in the control group, and lower in the BLM+Bai than in the BLM group ( P<0.05). The relative expression of pAMPK and NRF2 was 0.28±0.02 and 0.38±0.09 after Compound C+Baicalein treatment, which was lower than that of 0.56±0.07 and 0.60±0.08 in the BLM+Bai group ( P<0.05). The relative expression of ROS increased from 1.75±0.16 to 3.45±0.12 ( P<0.001). The proportion of positivity in the BLM+Bai+Compound C, BLM+Bai and control groups was 47.30%±4.29%, 18.18%±3.89% and 7.70%±3.53% ( F=109.700, P<0.001), respectively, with the BLM+Bai+Compound C group being higher than that in the BLM+Bai group ( P<0.05). Conclusion:The downregulation of Sirt1 expression in patients with osteoarthritis leads to FLS senescence and accelerates the progression of osteoarthritis. Baicalein can inhibit FLS senescence by activating Sirt1/AMPK/NRF2 pathway, which may delay the progression of osteoarthritis and improve the function of chondrocytes.

Objective To investigated the protective effect and immunology mechanism of Astragaloside Ⅳ(Ast) on rat renal ischemia-reperfusion injury model. Methods The SD rats were randomly divided into four group as the control, sham-operation, renal ischemia-reperfusion injury, and Ast treatment groups. Rat serum and urine were collected and detective for kidney function and interleukin cytokines. The kidney tissue was collected for histology exam. The rats in astragaloside group were intraperitoneally injected with 100 mg/kg astragaloside, and the other three groups were intraperitoneally injected with an equal volume of normal saline. The models of renal ischemia-reperfusion injury were prepared to generate in model and astragaloside groups, after 30 minutes of astragaloside injection. The rats with renal ischemia-reperfusion injury model were sacrificed after 24 hours, and the level of blood-urine creatinine, neutrophil gelatinase-associated lipocalin and Kidney damage molecule-1 were determined. The level of Th1 type cytokines (TNF-α, IFN-γ, IL-2) and Th2 type cytokines (IL-4, IL-5, IL-10) in serum were measured by using ELISA. The protein and gene expression of TNF-α, IFN-γ, IL-2, IL-4, IL-5, IL-10 in renal tissue were tested by western blot and PCR, respectively. The pathological changes and apoptosis of renal tissue in each group were detected by HE staining and TUNEL staining, respectively. The expression of CD20 protein in renal tissue was determined by immunohistochemistry. Results Compared with the model group, Ast treatment reduced serum creatinine (58.74 ± 9.44 μmol/L vs. 85.03 ± 23.48 μmol/L), increased creatinine clearance rate (0.81 ± 0.13 ml/min vs. 0.37 ± 0.08 ml/min), and reduce urine neutrophil gelatinase-associated lipocalin (NGAL) (579.34 ± 11.70 pg/ml vs. 827.60 ± 14.48 pg/ml), kidney injury molecule-1 (KIM-1) (105.06 ± 2.10 pg/ml vs. 151.67 ± 3.06 pg/ml) (P<0.05). Compared with the model group, Ast treatment alleviated renal tubular epithelial cell injury and significantly decreased the apoptosis (14.36 ± 1.36% vs. 28.63 ± 2.03%) (P<0.05), and significantly decreased the serum TNF-α (361.44 ± 9.66 pg/ml vs. 515.93 ± 10.61 pg/ml), IFN-γ (64.11 ± 1.21 pg/ml vs. 93.51 ± 2.15 pg/ml), IL-2 (388.33 ± 1.21 pg/ml vs. 557.82 ± 15.29 pg/ml), IL-4 (60.89 ± 1.21 pg/ml vs. 95.56 ± 2.75 pg/ml), IL-5 (94.02 ± 2.81 pg/ml vs. 147.07 ± 3.50 pg/ml), and IL-10 (52.62 ± 2.51 pg/ml vs. 78.22 ± 3.24 pg/ml) (P<0.01). Compared with the model group, Ast treatment significantly decreased the kidney TNF-α mRNA (1.89 ± 0.59 vs. 2.87 ± 0.97), IFN-γ mRNA (3.11 ± 1.02 vs. 5.98 ± 1.52), IL-2 mRNA (1.68 ± 0.44 vs. 4.09 ± 1.65), IL-4 mRNA (2.41 ± 0.81 vs. 4.69 ± 1.62), IL-5 mRNA (1.56 ± 0.19 vs. 2.92 ± 0.55), IL-10 mRNA (1.45 ± 0.14 vs. 2.85 ± 0.32) (P<0.01). The ratio of IL-4 to IFN-γ was basically restored to the level of sham operation group (1.05 ± 0.02 vs. 1.02 ± 0.06) (P<0.01), and CD20 cells in renal tissue was reduced. Conclusions The Th1 and B lymphocytes play an important role in renal ischemia reperfusion injury, and Th2 cells play a protective role. Astragaloside can regulate the imbalance of Th1/Th2 in the early stage after acute renal injury, and alleviate renal tubular injury.

Objective Less surveys on the economic burden of hepatitis B (HB)-related diseases have been conducted in China,so the socioeconomic harm caused by the diseases is not clear and the key parameters for economic evaluation of hepatitis B prevention and treatment are lacking.This study aimed to analyze the direct,indirect and intangible expenditures of hospitalized patients with HB-related diseases during hospitalization and during a year in different areas of China.Methods The hospitals for infectious diseases and the large general hospitals in 12 areas in China were selected in the study.All the inpatients with HB-related diseases were surveyed by cluster sampling of consecutive cases.The direct expenditure included direct medical cost and direct non-medical cost.The indirect expenditure,including work loss of patients and caregivers,were calculated by using human capital method for urban and rural populations in 12 areas.The intangible expenditure were reflected by willing to pay and stochastic tournament.The influencing factors of direct and indirect costs were identified by stepwise linear multi-variation regression analysis.Results A total of 27 hospitals in 12 areas were included in the survey.A total of 4 718 cases were surveyed,the overall response rate was 77.7％.The average hospital stay was 29.2 days (27-34) and the hospitalization expenditure was averagely 16 832.80 yuan (RMB) per case,in which the highest proportion (61.2％)was medicine fees [10 365.10 yuan (RMB)].The average direct expenditure and indirect expenditure were consistent with the severity of illness,which were 18 336.10 yuan (RMB) and 4 759.60 yuan (RMB) respectively,with the ratio of 3.85:1.The direct medical expenditure [17 434.70 yuan (RMB)] were substantially higher than the direct non-medical expenditure [901.40 yuan (RMB)].It was found that the hospitalization expenses was highest in direct medical expenditure and the transportation expenses was highest in direct non-medical expenditures.Among the average indirect expenditure,the loss of income for the patients [3 832.50 yuan (RMB)] was higher than that for the caregivers [927.20 yuan (RMB)],The total direct and indirect expenditure was highest for liver transplantation,followed by severe hepatitis,hepatocellular carcinoma and decompensated cirrhosis,acute hepatitis B,compensated cirrhosis and chronic hepatitis B.The influencing factors for both direct and indirect expenditure were high hospital level,severity of hepatitis B,living in urban area,antiviral therapy,long hospitalization and monthly income of family.For average 3.74 outpatient visits and 1.51 hospitalization,the average annual direct,indirect and intangible expenditure for HB-related diseases were 30 135.30,6 253.80 and 44 729.90 yuan (RMB) [totally 81 119.00 yuan (RMB)],accounting for 37.3％,7.7％ and 55.0％,respectively.Of the annual direct medical expenditure [28 402.80 yuan (RMB)],which were much higher than non-medical expenditure [1 732.50 yuan (RMB)],hospitalization expenditure [26 074.20 yuan (RMB)] was higher than outpatient visit expenditure [4 061.10 yuan (RMB)].The annual indirect expenditures for outpatient visit and hospitalization were 763.60 and 5 490.10 yuan (RMB),respectively.Of the annual intangible expenditure,the highest was that for/primary hepatocellular carcinoma,followed by cirrhosis,chronic hepatitis B,severe hepatitis B,liver transplantation and acute hepatitis B.Conclusions A heavy economic burden has been caused by HB-related diseases in China,and patients are more likely to rely on medical service rather than non-medical service.It is necessary to take effective treatment measures to prevent the adverse outcome of HB related diseases and achieve significant economic benefits.The influence of HB related diseases on mental health of the people can be reflected by an economics term,intangible expenditure.
