ObjectiveTo investigate the effect and mechanism of Qingre Sanzhuo decoction in treating gouty arthritis （GA） combined with hyperuricaemia （HUA）. MethodsSixty male SD rats were randomized into normal， model， colchicine （0.5 mg·kg^-1）， and low-， medium-， and high-dose （17， 34， 68 g·kg^-1， respectively） Qingre Sanzhuo decoction groups （n=10）. The rats in other groups except the normal group were treated with the modified method for the modeling of GA combined with HUA. The drug intervention groups were administrated with corresponding drugs by gavage in the afternoon every day and the normal group and the model group were administrated with an equal volume of sterile normal saline by gavage. The level of uric acid （SUA） in the serum was measured 2 h after the last administration. The degree of ankle joint swelling was calculated 0.5， 12， 24， 48 h after modeling， and joint inflammation was scored. The pathological changes of ankle joints were observed by hematoxylin-eosin staining， and the serum levels of tumor necrosis factor-α （TNF-α）， interleukin-1β （IL-1β）， C reactive protein （CRP）， and interleukin-18 （IL-18） were measured by enzyme-linked immunosorbent assay. Real-time PCR was performed to determine the mRNA levels of NOD-like receptor protein 3 （NLRP3）， apoptosis-associated speck-like protein containing CARD （ASC）， cysteinyl aspartate-specific protease-1 （Caspase-1）， gasdermin D （GSDMD）， and nuclear factor-kappa B （NF-κB） in the synovial tissue of ankle joints. Western blot was employed to determine the protein levels of NLRP3， ASC， and Caspase-1 in ankle joints. The immunohistochemical method was used to detect the expression of GSDMD and NF-κB in the synovial tissue of ankle joints. ResultsCompared with the normal group， the model group showed increased SUA in the serum （P<0.05）， ankle joint swelling and joint inflammation （P<0.05）， increased number of blood vessels in the synovium， inflammatory cell foci in the synovial bursa， elevated serum levels of TNF-α， IL-1β， CRP， and IL-18 （P<0.05）， and up-regulated mRNA and protein levels of NLRP3， ASC， Caspase-1， GSDMD， and NF-κB in the synovial tissue of ankle joints （P<0.05）. Compared with the model group， the medium- and high-dose Qingre Sanzhuo decoction groups showed reduced SUA in the serum （P<0.05）， alleviated ankle joint swelling and joint inflammation （P<0.05）， lowered serum levels of TNF-α， IL-1β， CRP， and IL-18 （P<0.05）， and down-regulated mRNA and protein levels of NLRP3， ASC， Caspase-1， GSDMD， and NF-κB in the synovial tissue of ankle joints （P<0.05）. However， in terms of ameliorating the pathological changes of ankle joints， only the high-dose Qingre Sanzhuo decoction group showed normal morphology of the synovial membrane of ankle joints and no obvious lesion in the articular cartilage. ConclusionQingre Sanzhuo decoction may play a role in preventing and controlling GA combined with HUA by down-regulating the activity of NLRP3/ASC/Caspase-1 pathway and inhibiting the expression of inflammatory cytokines， such as TNF-α， IL-1β， CRP， and IL-18.

Objective:To observe Leber's hereditary optic neuropathy (LHON) microperimetry features, discuss its significance in diagnosis and treatment of LHON assessment.Methods:A retrospective clinical study. A total of 13 LHON patients (25 eyes) diagnosed in Department of Ophthalmology of the First Affiliated Hospital of Army Medical University from May 2015 to May 2020 (disease group) were included in the study, including 9 males (18 eyes) and 4 females (7 eyes), and beginning with the age of 15.0 (10.0, 57.0). Ten healthy volunteers (19 eyes) were selected as the normal group, including 7 males (13 eyes) and 3 females (6 eyes), aged 22.0 (6.0, 46.0) years at the first diagnosis. According to the course is divided into: asymptomatic group (carriers), subacute (<6 months), the dynamic group (6-12 months), chronic group (>12 months). There were 7, 6, 5 and 7 eyes, respectively. All eyes underwent best corrected visual acuity (BCVA) and microperimetry. BCVA test was performed using the international standard visual acuity chart, which was statistically converted to the logarithm of the minimum Angle of resolution (logMAR) visual acuity. MP-3 microperimetry was used to perform microperimetry, and the mean sensitivity (MS) values of five regions were recorded: center, superior, temporal, inferior, and nasal. Mann-Whitney U test was used for comparison between two groups, and Kruskal-Wallis H test was used for comparison between multiple groups. Results:Compared with the normal group, MS in the center, superior, temporal, inferior and nasal of the diseased group decreased, and the differences were statistically significant ( Z=-5.629, -4.906, -5.630, -5.631, -5.227; P<0.05). There were significant differences in different regions of MS between different course groups ( H=12.296, 11.583, 10.110, 12.994, 8.663; P<0.05). There were significant differences in logMAR BCVA and central MS between asymptomatic group and subacute group ( P=0.040, 0.007). There were significant differences in temporal, inferior and superior MS between subacute group and dynamic group ( P=0.026, 0.017, 0.018). Dynamic and chronic group, MS above the difference was statistically significant ( P=0.031). Idebenone treatment significantly improved visual field defects in 4 of 23 eyes. Conclusions:In the early stage of LHON, the central visual field defect gradually progresses to the temporal, inferior and superior areas, and the temporal and inferior areas are more severe. Visual field defects reached a stable level at 6-12 months. MP-3 can assist in early diagnosis of LHON, and provide reliable basis for efficacy evaluation.

Objective To evaluate the clinical efficacy and safety of CT-guided percutaneous osteoplasty(POP)in the treatment of osteolytic metastases of the pelvis.Methods The clinical data of a total of 40 patients with pelvic osteolytic metastases,who received CT-guided POP at the Affiliated Zhongda Hospital of Southeast University between October 2011 and December 2021,were collected.Visual analogue scale(VAS)score was used to evaluate the clinical pain relief degree at one week,one month,3 months,6 months and 12 months after POP,and the joint function and the used dose of analgesic drugs were recorded.The preoperative and the postoperative 3-month,6-month and 12-month extents of the pelvic tumor destruction were compared.Based on the progression of local lesions within 12 months of follow-up,the patients were divided into controlled group and progression group.The proportion of using systemic anti-tumor therapy,the size of lesion,the amount of bone cement injected,and the cement filling ratio were compared between the two groups.Results Successful surgical procedure was accomplished for 57 lesions in 40 patients.The mean amount of bone cement injected was(4.56±2.25)mUpoint.In the 40 patients,the preoperative and the postoperative one-week,one-month and 3-month VAS score were(8.00±0.85)points,(2.05±0.96)points,(2.08±0.94)points and(2.18±0.84)points respectively,the difference in VAS score between preoperative value and postoperative one-week value was statistically significant(P＜0.01).In 37 patients,the postoperative 6-month VAS score was(2.35±0.54)points;and in 28 patients,the postoperative 12-month VAS score was(2.43±0.79)points.The differences in VAS score between postoperative one-week value and postoperative one-month,3-month,6-month,and 12-month values were not statistically significant(all P＞0.05),while the differences in VAS score between preoperative value and postoperative values were statistically significant(F=316.3,P＜0.01).The postoperative 3-month,6-month,and 12-month local control rates were 96.49％,85.19％,and 78.12％respectively,the differences between each other among the above three values were statistically significant(P=0.026).No statistically significant differences in the proportion of using systemic anti-tumor therapy,the lesion size and the amount of bone cement injected existed between the controlled group and the progression group(all P＞0.05).The cement filling ratio in the controlled group and the progression group was(81.26±9.17)％and(68.40±12.98)％respectively,and the difference between the two groups was statistically significant(P＜0.01).Conclusion For the treatment of pelvic metastases,CT-guided POP is clinically safe and effective.The injected bone cement can control the progression of local lesions for a longer time.(J Intervent Radiol,2023,32:1197-1201)

Objective To investigate the effect of intestinal mucosal Toll-like receptor 4/nuclear factor κB (TLR4/NF-κB) signaling pathway on renal damage in pseudo-sterile IgA nephropathy (IgAN) mice. Methods C57BL/6 mice were randomly divided into experimental group (pseudosterile mouse model group), control group (IgAN mouse model group), pseudosterile mouse blank group, and normal mouse blank group. Pseudosterile mice were established by intragastric administration of quadruple antibiotics once a day for 14 days. The pseudosterile IgAN mouse model was set up by combination of oral bovine serum albumin (BSA) administration and staphylococcal enterotoxin B (SEB) injection. The pathological changes of renal tissue were observed by immunofluorescence staining and PAS staining, and the intestinal mucosa barrier damage indicators lipopolysaccharide(LPS), soluble intercellular adhesion molecule 1(sICAM-1) and D-lactate(D-LAC) were analyzed by ELISA. Biochemical analysis was used to test 24 hour urine protein, serum creatinine and blood urea nitrogen. The mRNA and protein levels of Toll-like receptor 4 (TLR4), myeloid differentiation factor 88 (MyD88) and nuclear factor κB (NF-κB) were detected by reverse transcription PCR and Western blot analysis. Results The kidney damage of pseudosterile IgAN mice was more severe than that of IgAN mice, and the expressions of intestinal mucosal barrier damage markers (LPS, sICAM-1 and D-LAC) were significantly increased in pseudosterile IgAN mice. In addition, the expressions of TLR4, MyD88, and NF-κB level were all up-regulated in the intestinal tissues of IgAN pseudosterile mice. Conclusion Intestinal flora disturbance leads to intestinal mucosal barrier damage and induces activation of TLR4 signaling pathway to mediate renal injury in IgAN.

Pediatric idiopathic nephrotic syndrome (INS) is characterized by massive albuminuria, hypoproteinemia, edema and hyperlipidemia, with a long course and high probability of relapse and prolongation. Long-term complications caused by long-term usage of hormones and immunosuppressants in children with INS seriously affect their physical and mental health and quality of life. Most children with steroid-sensitive nephrotic syndrome can be cured before adulthood, while some of them relapse in adulthood. Long-term prognosis of children with steroid-resistant nephrotic syndrome is poor. There have been few studies in China followed the long-term outcomes and its related factors of children with INS over 10 years. The paper reviewed the literatures on the long-term outcomes of children with INS, including renal survival, growth, mental health, learning and work, marriage and fertility, disease recurrence and long-term related complications, to explore the factors related to the poor long-term outcomes of children with INS and to assist in clinical decision-making and follow-up management.

Objective: To investigate the refractive progression and associated factors of children of different ages and refractive status, and to provide guidance on myopia prevention and control program formulation and work practice. Methods: A total of 20 kindergartens, primary schools, and secondary schools in 2 districts of Shanghai were selected based on the existing cohort, and baseline data in 2015 and one year follow up data in 2016 were collected from 1 510 children aged 4 to 14, including cycloplegic spherical equivalent refraction (SER), axial length (AL), and corneal curvature. The distribution and progression of SER and AL in children of different ages and refractive status were analyzed, and the influencing factors of SER progression (ΔSER) were explored using multiple linear regression. Results: ΔSER remained relatively stable at age 4 and 5 (average -0.08 to -0.07 D/year), and SER drifted significantly towards myopia (average -0.50 to -0.31 D/year) in all groups older than 6 years, dropping back to -0.44 to -0.33 D/year after age 11; Elongation of AL (ΔAL) was 0.27 to 0.35 mm/year in 4 to 10 years group, and decreased to 0.15 to 0.22 mm/year in 11 to 14 years group. The ΔSER and ΔAL were greatest in the new onset myopes [(-0.90± 0.05 )D, (0.51±0.02)mm], followed by the low myopia group [(-0.68±0.04)D, (0.36±0.02)mm], then followed by the moderate to high myopia group[(-0.49±0.06)D，(0.23±0.03)mm] and the lowest in the hyperopia group[(-0.21±0.02)D, ( 0.26 ±0.01)mm], with a statistically significant difference among these groups ( P <0.05). Age ( β =-0.07), baseline SER ( β = 0.05 ) and ΔAL ( β =-0.78) were independent influencing factors for refractive progression in the 4 to 10 years old group, while ΔAL( β =-1.55) was the only independent influencing factor in the 11 to 14 years old group ( P <0.05). Conclusion The elongation of AL in preschoolers is mostly physiologically and should be prevented from growing beyond the physiological range by increasing outdoor activities. The primary students, as well as students with pre myopia or low myopia are the priority groups for dynamic monitoring and intervention in myopia prevention and control.

Objective: To analyze the distribution of uncorrected visual acuity in children and adolescents aged 3-18 years with relative safe refractive range, and to develop the growth curve and reference range of uncorrected visual acuity in children and adolescents of different ages, so as to provide reference for formulating the referral threshold for myopia screening practice. Methods: Using cluster sampling method, 9 146 children and adolescents aged 3-18 years old in Shanghai were selected for uncorrected visual acuity, cycloplegic refraction, slit lamp and other ophthalmic examinations, and the percentiles and growth curve of uncorrected visual acuity of children and adolescents in the relative safe refractive range were fitted by LMS method. Besides, the area under the ROC curve and the sensitivity and specificity of different cut-off values were analyzed. Results: The uncorrected visual acuity was skewed, with a median of 4.8. There were 4 675 individuals with safe refraction, the median of uncorrected visual acuity in which was 4.9. The LMS curve showed that the uncorrected visual acuity increased with age in the lower age group, and gradually stabilized to the best level at the age of 6-10. P 50 was 4.8 in 3-4 years old, 4.9 in 5-8 years old, 5.0 in 9 years old and above. The area under ROC curve of uncorrected visual acuity predicting refractive abnormality increased with age, with the lowest value of 0.55(95%CI=0.50-0.61) at 3 years old and the highest value of 0.95 (95%CI=0.94-0.96) at 12-18 years old. The Youden index was the highest for P25 at 3-6 years old, and the highest for P 10 at 7 years old and above. With the increase of the cut off value, the sensitivity increased and the specificity decreased. Conclusion The uncorrected visual acuity increases gradually with age, and reaches the best level after 6-10 years old. The screening effect of uncorrected visual acuity predicting refractive abnormality increased with age. It is suggested that the referral threshold of children and adolescents with abnormal uncorrected visual acuity should be set according to their ages, and P 25-P 75 can be selected according to the screening purposes.

Ametropic visual impairment has become a public health problem in China and even in the world, especially the prevention and control of myopia development, and the Chinese government attaches great importances to the eye health of school-age children and adolescents.The establishment of visual health archives and the screening of refractive errors are important managements prevention and control.However, there has always been a lack of relevant domestic or international screening specifications, and which may result in screening implementation subject confusion, inconsistent screening indicators and boundary values, unscientific operation methods and feedback in the routine screening work in China.With the push and support of National Health Commission, a recommended national health standard Specification for Screening of Refractive Error in School-age Children and Adolescents (WS/T 663-2019) was officially issued on January 11, 2020 and will be implemented from June 1, 2020, which clarified the technical standardization for the specific requirement, methods, referral recommendation and management during screening of refractive error in school-age children and adolescents.Implementing an effective screening and prevention of ametropic visual impairment in school-age children and adolescents according to the standard is an important task and responsibility of medical and educational institutions.

Objective:To investigate whether the presence of complement factor H( CFH) gene polymorphisms is associated with unexplained mild visual loss (UMVL) in type 2 diabetes mellitus patients. Methods:A case control study was adopted.The participants included two groups from a previous population-based epidemiology study on type 2 diabetes mellitus patients in the Beixinjing community, Shanghai: UMVL was defined by a best corrected visual acuity(BCVA)<20/25 and≥20/63 in both eyes, with no eye diseases causing visual impairment, such as corneal diseases, cataract, age-related macular degeneration, glaucoma, optic nerve atrophy, diabetic retinopathy, etc.Genomic DNA was isolated from the peripheral venous blood of all the participants and then loaded onto Fluidigm Digital Arrays.Four CFH gene single nucleotide polymorphisms (SNPs)(rs800292, rs1061170, rs529825, rs1410996, rs203674) were assessed with the SPSS 13.0 and HAPLoVIEW 4.0 software to test the statistical association of CFH polymorphisms with UMVL.The study protocol was approved by the Ethics Committee of Shanghai General Hospital, Shanghai Jiaotong University(No.2013KY023). All the procedures were conducted according to the tenets of the Declaration of Helsinki.Written informed consent was obtained from each subject prior to entering the study cohort. Results:Total of 135 residents with UMVL and 133 with normal vision(BCVA≥20/25 in both eyes) were enrolled.The UMVL group matched the control group in terms of gender, age, onset age, and duration of diabetes mellitus, hemoglobin A1c levels, and body mass index(all at P>0.05). The four SNPs(rs800292, rs1061170, rs529825, rs1410996) except rs203674 tested in the UMVL and control groups were qualified by the Hardy-Weinberg equilibrium ( P>0.05). There were no differences in SNPs and genotypes between the two groups in the four loci of the CFH gene.The P value of allele frequencies of rs529825, rs800292, rs1410996 and rs1061170 were 0.79, 0.25, 0.69 and 0.77, respectively, and the P value of genotype frequencies were 0.61, 0.69, 0.87 and 0.43, respectively. Conclusions:There is no correlation between CFH gene polymorphism and UMVL in type 2 diabetic patients.
