Objective: To investigate the serum uric acid levels among residents living in Balikun County, Xinjiang Uygur Autonomous Region from 2018 to 2021, so as to provide insights into local hyperuricemia control. Methods: The residents at ages of 20 to 69 years undergoing physical examinations in Balikun County Hospital during the period from 2018 to 2021 were enrolled. Their age, gender, and history of medication and disease were collected, and serum uric acid levels were measured. The gender- and age-specific prevalence of hyperuricemia and hypouricemia was descriptively analyzed. Results: A total of 3 097 subjects were enrolled, which included 1 210 males ( 39.07% ) and 1 887 females ( 60.93% ) and had a mean age of ( 46.12±12.84 ) years. The overall mean serum uric acid was ( 260.41±71.99 ) μmol/L, and the mean serum uric acid was ( 298.22±69.57 ) μmol/L in men and ( 236.17±62.44 ) μmol/L in women. The serum uric acid level appeared a tendency towards a rise with ages both in whole study subjects and in women ( P<0.05 ). The overall prevalence of hyperuricemia was 4.26%, with 4.63% prevalence in men and 4.03% in women. The prevalence of hyperuricemia appeared a tendency towards a rise with ages both in whole study subjects and in women ( P<0.05 ). The overall prevalence of hypouricemia was 0.71%, with 0.25% prevalence in men and 1.01% in women; the prevalence of moderate hypouricemia was 11.11%, with 2.56% prevalence in men and 16.59% in women. Conclusions Low level of serum uric acid and prevalence of hyperuricemia is detected among residents living in Balikun County. Monitoring of serum uric acid is recommended to be intensified among men.

OBJECTIVE: To evaluate the clinical value of accelerated rehabilitation in the treatment of intertrochanteric fracture of femur in the elderly. METHODS: Eighty elderly patients with intertrochanteric fractures were selected from January 2016 to October 2018, and were divided into accelerated rehabilitation group and traditional rehabilitation group according to different treatment schemes, 40 cases in each group. There were 22 males and 18 females in accelerated rehabilitation group with an average age of (78.5±9.1) years old; 19 males and 21 females in traditional rehabilitation group with an average age of (80.6±8.1) years old. The perioperative blood loss, incidence of complications, hospitalization time, hospital stay, Harris hip score and improved BADL scale were compared between the two groups. RESULTS: Eighty patients were followed up for more than 12 months, with an average follow-up time of (15.4±2.6) months. The total perioperative blood loss in the accelerated rehabilitation group was significantly lower than that in the traditional rehabilitation group(<0.001). Although the incidence of complications in the accelerated rehabilitation group was lower than that in the traditional rehabilitation group, there was no significant difference between the two groups(>0.05). The time from admission to operation of the accelerated rehabilitation group(1.48±0.51) days was significantly shorter than that of the traditional rehabilitation group(4.35±1.55) days(<0.01);the hospitalization time of the accelerated rehabilitation group was(6.4±1.1) days was significantly shorter than that of the traditional rehabilitation group (9.9±1.9) days(<0.01). At 12 months after operation, there was no significant difference in Harris score between the two groups(>0.05), and there was no significant difference in modified BADL score between the two groups(>0.05). CONCLUSIONS The application of accelerated rehabilitation program in elderly intertrochanteric fracture is safe and effective. It can reduce perioperative bleeding, shorten hospitalization time and accelerate the recovery of hip function.

The nursing students of Grade 2009 to Grade 2016 were selected.Their skills,midterm,usual and final performances as well as comprehensive scores of normal human morphology course were analyzed by one-way ANOVA in combination with different stages of curriculum integration in order to compare the teaching effect between traditional teaching mode + evaluation system and mixed teaching mode + formative evaluation in the course of normal human morphology.Statistical analysis by SPSS 17.0 showed that the average score of formation stage (traditional teaching mode) was 67.55 ± 12.72,the average score of integration stage (mixed teaching mode) was 72.79 ± 10.93 and the average score of development stage (formative evaluation +mixed teaching mode) was 83.94 ± 9.58.After making comparisons,the P values of ANOVA of the course of normal human body morphology in all stages were all less than 0.001,having statistical significance.The results showed that the overall development of the curriculum is becoming mature and the new teaching model can help students who usually do not like to review.

Liver fibrosis is a significant health burden,marked by the consistent deposition of collagen.Unfortunately,the currently available treatment approaches for this condition are far from optimal.Lysyl oxidase-like protein 2(LOXL2)secreted by hepatic stellate cells(HSCs)is a crucial player in the cross-linking of matrix collagen and is a significant target for treating liver fibrosis.Mesenchymal stem cell-derived small extracellular vesicles(MSC-sEVs)have been proposed as a potential treatment option for chronic liver disorders.Previous studies have found that MSC-sEV can be used for microRNA delivery into target cells or tissues.It is currently unclear whether microRNA-4465(miR-4465)can target LOXL2 and inhibit HSC activation.Additionally,it is uncertain whether MSC-sEV can be utilized as a gene therapy vector to carry miR-4465 and effectively inhibit the progression of liver fibrosis.This study explored the effect of miR-4465-modified MSC-sEV(MSC-sEVmiR-4465)on LOXL2 expression and liver fibrosis development.The results showed that miR-4465 can bind specifically to the promoter of the LOXL2 gene in HSC.Moreover,MSC-sEVmiR-4465 inhibited HSC activation and collagen expression by downregulating LOXL2 expression in vitro.MSC-sEVmiR-4465 injection could reduce HSC activation and collagen deposition in the CCl4-induced mouse model.MSC-sEVmiR-4465 mediating via LOXL2 also hindered the migration and invasion of HepG2 cells.In conclusion,we found that MSC-sEV can deliver miR-4465 into HSC to alleviate liver fibrosis via altering LOXL2,which might provide a promising therapeutic strategy for liver diseases.

BACKGROUND:In recent years,the incidence of hyperuricemia caused by purine metabolism disorders has been increasing,which can induce inflammatory responses and lead to renal injury. OBJECTIVE:To explore the role and mechanism of solute carrier family 2 member 12(SLC2A12)in hyperuricemia-related renal injury. METHODS:Renal tubular cells(HK2 cells)were divided into five groups:HK2 group,HK2+uric acid group,HK2+uric acid+NC group,HK2+uric acid+siSLC2A12 group,and HK2+uric acid+siSLC2A12+MK-2206 group.HK2 cells were treated with uric acid and transfected with siRNA SLC2A12,followed by MK-2206 treatment to inhibit AKT expression.Cell proliferation was detected by CCK-8 assay.Apoptosis was detected by TUNEL assay.qRT-PCR and western blot assay were used to detect fibrogenic factors as well as activation of the AKT/FOXO3a pathway.The concentrations of inflammatory cytokines were measured by enzyme-linked immunosorbent assay. RESULTS AND CONCLUSION:(1)Uric acid treatment inhibited cell proliferation and promoted cell apoptosis in the HK2+uric acid group compared with the HK2 group.The proliferative ability of cells in the HK2+uric acid+siSLC2A12 group was further decreased and apoptotic cells were further increased compared with the HK2 group.Compared with the HK2+uric acid+siSLC2A12 group,the HK2+uric acid+siSLC2A12+MK-2206 group showed an increase in cell proliferation and a decrease in apoptotic cells.(2)Compared with the HK2 group,the connective tissue growth factor(CTGF),α-smooth muscle actin(α-SMA)and transforming growth factor beta(TGF-β)expressions increased in the HK2+uric acid group;CTGF,α-SMA and TGF-β expression further increased in the HK2+uric acid+siSLC2A12 group.Compared with the HK2+uric acid+siSLC2A12 group,the CTGF,α-SMA and TGF-β expressions decreased.(3)Compared with the HK2 group,the expression of p-AKT,FOXO3a,and p-FOXO3a elevated in the HK2+uric acid group;the expression of p-AKT further increased,while the expression of FOXO3a and p-FOXO3a decreased in the HK2+uric acid+siSLC2A12 group.Compared with the HK2+uric acid+siSLC2A12 group,p-AKT expression decreased;FOXO3a and p-FOXO3a expression increased in the HK2+uric acid+siSLC2A12+MK-2206 group.(4)Compared with the HK2 group,interleukin-6,interleukin-1 β,and tumor necrosis factor α levels increased in the HK2+uric acid group;interleukin-6,interleukin-1 β,and tumor necrosis factor α levels further increased in the HK2+uric acid+siSLC2A12 group.Compared with the HK2+uric acid+siSLC2A12 group,interleukin-6,interleukin-1 β,and tumor necrosis factor α levels diminished in the HK2+uric acid+siSLC2A12+MK-2206 group.(5)These findings indicate that SLC2A12 may protect against hyperuricemia-induced renal injury by counteracting uric acid-induced tubular fibrosis and inflammation through activation of the FOXO3a pathway.

As the largest ecosystem of human body, intestinal microorganisms participate in the synthesis and metabolism of uric acid. Developing and utilizing intestinal bacteria to degrade uric acid might provide new ideas for the treatment of hyperuricemia. The fecal samples of people with low uric acid were inoculated into uric acid selective medium with the concentration of 1.5 mmol/L for preliminary screening, and the initially screened strains that may have degradation ability were domesticated by concentration gradient method, and the strains with high uric acid degradation rate were identified by 16S rRNA sequencing method. A strain of high-efficiency uric acid degrading bacteria was screened and domesticated from the feces of people with low uric acid. The degradation rate of uric acid could reach 50.2%. It was identified as Escherichia coli. The isolation and domestication of high efficient uric acid degrading strains can not only provide scientific basis for the study of the mechanism of intestinal microbial degradation of uric acid, but also reserve biological strains for the treatment of hyperuricemia and gout in the future.
