Résumé
Osteoarthritis (OA) is a common chronic, highly prevalent, painful, and disabling degenerative joint disease. It has imposed a heavy burden on social healthcare and patients' psychology and economy due to its clinical symptoms such as impaired joint mobility and severe joint pain and the immature therapies. Studies have shown that OA is closely associated with articular cartilage dysfunction, synthesis and degradation disorders of chondrocyte extracellular matrix (ECM), and joint inflammation. Moderate autophagy can restore the function of damaged chondrocytes, regulate chondrocyte apoptosis, and promote the synthesis and metabolism of ECM to alleviate the inflammation of joints and delay the onset and progression of OA. According to the clinical symptoms, OA can be classified into the category of impediment in traditional Chinese medicine. With the theories of holistic conception, treatment based on syndrome differentiation, and individualised diagnosis and treatment, traditional Chinese medicine has demonstrated definite effects in the treatment of OA in thousands of years of practice. Moreover, traditional Chinese medicine causes mild adverse reactions, and the patients have high tolerance and acceptance. This paper briefly explains the roles of autophagy and the related regulatory proteins, such as Unc-51-like autophagy-activated kinase 1 (ULK1), Beclin-1, and microtubule-associated protein light chain 3 (LC3), and details the latest research achievements in the prevention and control of OA by traditional Chinese medicines and its related markers via the regulation of autophagy, so as to provide a idea for the in-depth research in this field and the clinical application of traditional Chinese medicine in preventing and treating OA.
Résumé
Guided by the theory of "kidney generates marrow", the study elaborates the viewpoint that the route of Yin Heel Channel (阴跷脉) is consistent with the "kidney-marrow-brain" axis from the perspective of the circulation of the meridians and the relationship between the zang-fu organs. Accordingly, it is believed that disease of Yin Heel Channel and dysfunction of the "kidney-marrow-brain" axis are the core pathogenesis of children enuresis, and it is elaborated from the following three major aspects, firstly, insufficient kidney essence, dysfunction of the "kidney-marrow-brain" axis, secondly, disease of Yin Heel Channel and deficiency and cold in lower jiao, and thirdly, disease of Yin Heel Channel and loss of nourishment of Chong Vessel. It is proposed to use the mode of "firstly needle, secondly moxibustion, and lastly consolidation" to treat children enuresis. Needle is to adjust yin and yang, warm yang and tonify kidney, and wake up the brain and open the orifices. The acupoints in Yin Heel Channel such as Zhaohai (KI 6), Jiaoxin (KI 8) and confluence points of the eight extraordinary vessels such as Waiguan (TE 5), Zulinqi (GB 41) are used, together with Baihui (GV 20), Yintang (EX-HN 3), Guanyuan (CV 4), Qixue (KI 13), Dazhong (KI 4). Moxibustion is to reinforce healthy qi and warm yang, bank up the root and consolidate the original qi by moxibustion at Shenque (CV 8), Mingmen (GV 4), and Xuanshu (GV 5). Consolidation is to use acupoints application to consolidate the therapeutic effect, and Guanyuan (CV 4) & Pangguangshu (BL 28), Qihai (CV 6) & Zhishi (BL 52), and Shenque (CV 8) & Ciliao (BL 32) are commonly used as the three groups of acupoints to warm the kidney and stop collapse, regulate and tonify the qi and blood.

ObjectiveTo construct traditional Chinese medicine (TCM) diagnostic scale of turbid toxin syndrome in order to provide corresponding reference for the standardization of TCM syndromes and studies. MethodsWe systematically searched the Chinese Medical Dictionary (CMD), China Knowledge Network (CNKI), Wanfang Data Knowledge Service Platform (WF) and VIP database for TCM classics and modern literature on turbid toxin syndrome, and initially screened the four diagnosis information of turbid toxin syndrome, established a pool of information entries, and conducted a cross-sectional clinical survey. Discrete trend method, correlation coefficient method, Cronbach's coefficient method, and factor analysis method were applied to objectively screen the entries. The diagnostic scale of turbid toxin syndrome were constructed through three rounds of Delphi method expert survey to determine the scale entries, using hierarchical analysis to get the judgement matrix scores and relative weight of each entry, after passing consistency test and then isometric expansion of the relative weight of the entries to get the weight of each entry and assign the value. ResultsA total of 35 articles were included, 45 entries were obtained after the initial screening. After the clinical investigation, 12 entries were not suitable by the discrete trend method, 23 entries not suitable by correlation coefficient method, 13 entries by the internal consistency screening were removed with the Cronbach's alpha coefficient rising, and 10 entries not suitable by the factor analysis method. Twenty-two entries were retained after objective screening by the combined use of the four statistical methods. The positive coefficients of experts in the three rounds of Delphi method of expert consultation were 96.67%, the coefficients of expert authority were 0.834, 0.856, and 0.867, and the coefficients of co-ordination were 0.126, 0.326, and 0.312, respectively. After consulting with clinical experts, and three rounds of Delphi method survey and hierarchical analysis method weight assignment, the diagnostic scale entries of turbid toxin syndrome were finally established. Primary symptoms: dark red or purple and dusky tongue, yellowish greasy or dry coating (10 points); sticky and unpleasant stools (8 points); disharmony of tastes including halitosis, sticky and greasy taste in the mouth, dry mouth and bitter taste in the mouth (6 points); unfavourable or yellowish or red urination (5 points); and dark complexion (4 points). Secondary symptoms: heavy body (3 points); dizziness (3 points); profuse, sticky, foul-smelling secretions (2 points); wiry and slippery, or slippery, or slippery and rapid pulse (2 points); feeling of hardness in the abdomen (1 point). ConclusionUsing Delphi method combined with the hierarchical analysis method, combining qualitative and quantitative study, a diagnostic scale of turbid toxin syndrome was initially developed.
Résumé
Osteoarthritis (OA), rheumatoid arthritis (RA), gouty arthritis (GA), and intervertebral disc degeneration (IVDD) are the most common bone and joint-related diseases in clinical practice. They can all affect related joints, leading to joint pain, swelling, dysfunction, and other symptoms. The difference is that OA is mainly caused by joint wear and age-related degradation and is manifested as joint pain, stiffness, and limited movement. RA is an autoimmune disease, manifested as joint pain, swelling, morning stiffness, and systemic symptoms. GA is caused by abnormal uric acid metabolism, manifested as acute arthritis, and IVDD is caused by intervertebral disc degeneration. Studies have shown that the mechanism of the occurrence and development of these bone and joint diseases is extremely complex. Pyroptosis is closely related to these bone and joint-related diseases by participating in bone and joint inflammation, cartilage metabolism imbalance, extracellular matrix degradation, and pathological damage of bone and joint. Inhibition of bone and joint-related pyroptosis will effectively prevent and treat bone and joint-related diseases. At the same time, many studies have confirmed that traditional Chinese medicine (TCM) has a prominent curative effect and obvious advantages in the prevention and treatment of bone and joint-related diseases. TCM can reduce the inflammatory reaction of bone and joints, improve the pathological damage of bone and joint diseases, and relieve bone and joint pain by inhibiting pyroptosis. Therefore, this article aims to briefly explain the relationship between pyroptosis and the occurrence and development of bone and joint-related diseases and summarize the latest research reports on the intervention of pyroptosis in the treatment of bone and joint-related diseases by TCM monomers, TCM extracts, and TCM compounds. It offers new ideas for the in-depth study of the pathogenesis and drug treatment of bone and joint diseases and provides a basis for the clinical use of TCM to prevent and treat bone and joint diseases.

Objective:To identify the method to reduce X-ray exposure during ablation of atrial fibrillation (AF) by comparing the cryoballoon (CRYO) ablation and remote magnetic navigation (RMN) ablation.Methods:A retrospective analysis was conducted on 144 patients undergoing CRYO ablation (CRYO group) and 121 patients undergoing RMN ablation (RMN group) in our hospital. Entrance surface doses at reference points online, exposure time during procedure and outcomes were analyzed for different types of patients.Results:Compared with the RMN group, the procedure time for the CRYO group significantly decreased [(165.0±23.6), (97.8±18.4) min, t=26.05, P<0.001]. However, the entrance surface dose value [(232.3±130.7), (669.0±387.5) mGy, Z=-12.29, P<0.001] and X-ray exposure time [(8.1±3.1), (23.4±6.2) min, t=-24.57, P<0.001] increased significantly for the CRYO group. No significant difference was found between the two groups in the proportion of maintaining sinus rhythm during follow-up of patients (71.9%, 75.7%, P=0.618). Multiple regression analysis showed that obese patients, patients with non-paroxysmal AF and patients with variant pulmonary veins were associated with an increase in entrance surface dose values in the CRYO group ( t=5.47, 2.23, 3.39, P<0.05). The X-ray exposure time for the three types patients above in the CRYO group also increased ( t=2.87, 3.86, 3.25, P<0.05) in the CRYO group. However, only obese patients in the RMN group had an increase in entrance surface dose value ( Z=-4.15, P<0.001) and no increase in exposure time. For the three types of patients above, there was no significant difference in proportion of maintaining sinus rhythm between the CRYO group and the RMN group during follow-up ( P>0.05). Conclusions:Compared with RMN ablation, the radiation exposure of CRYO AF ablation significantly increased, especially in obese patients, patients with non-paroxysmal AF and patients with pulmonary veins variation. The use of RMN for these types of patients may reduce the radiation exposure without affecting the procedure outcomes.

Objective:To explore the predictors of upper tract urothelial carcinoma (UTUC) invading muscle.Methods:The preoperative clinical data of 169 patients with UTUC who underwent radical nephroureterectomy (RNU) in the Department of Urology, Second Hospital of Tianjin Medical University from August 2019 to September 2021 were retrospectively collected. The average age of the patients was (67.7±8.3)years. There were 95 male cases (56.2%).15 cases (15.8%) were with diabetes, 46 cases (48.4%) with hypertension, 68 cases (71.6%) with hematuria, 44 cases (46.3%) with renal pelvis tumor, 74 cases (77.9%) with hydronephrosis and 8 cases (8.4%) with multifocality. There were 15 (20.3%), with diabetes, 40(54.1%) with hypertension, 58(78.4%)with hematuria, 32(43.2%) with renal pelvis tumor, 60(81.1%) with hydronephrosis and 2(2.7%) with multifocality among 74 female patients(43.8%), respectively. Patients’ body mass index (BMI) was (24.2±3.2) kg/m 2.The tumor diameter was (3.4±1.8) cm. The average count of neutrophil (NEU) was (4.2±1.7) ×10 9/L, with monocyte (MON) (0.4±0.2) ×10 9/L, platelet (PLT) (237.8±75.3) ×10 9/L and lymphocyte (LYM) (1.7±0.5) ×10 9/L. Neutrophil-to-lymphocyte ratio (NLR) was 2.7±1.4. Mmonocyte-to-lymphocyte ratio (MLR) was 0.3±0.1 and platelet-to-lymphocyte ratio (PLR) was 151.1±59.6. The concentrations of hemoglobin (Hb) and fibrinogen (FIB) were (127.1±18.3) g/L and(3.5±1.0) g/L. Univariate logistic regression analysis was performed on all preoperative data, and a nomogram was established to predict UTUC invading muscle by stepwise regression combined with multivariate logistic analysis. Concordance index (C-index) was used to evaluate the accuracy of the model, and Hosmer-Lemeshow test was used to check the fit. Using 1000 bootstrap resampling to validate the model and draw calibration plot. Receiver operating characteristics (ROC) curves were used to determine the most appropriate cut-off point of the model to predict tumor invasion and evaluate its sensitivity and specificity. Results:In this study, there were 169 cases. Postoperative pathological results showed that 18 cases (10.6%) were of low grade and 151 cases (89.4%) were of high grade. There were 2 patients (1.2%) with pT a stage, 44 patients (26.0%) with pT 1 stage, 37 patients (21.9%) with pT 2 stage, 81 patients (47.9%) with pT 3 stage and 5 patients (3.0%) with pT 4 stage. According to tumor stage, 46 patients were included into non-muscle invasive disease (NMID, pT a/T is/T 1) group and 123 patients were included into muscle invasive disease (MID, pT 2/T 3/T 4) group. Univariate analysis showed that hydronephrosis ( OR=2.919, 95% CI 1.332-6.387, P=0.007) was significantly correlated with MID. Tumor location in ureter ( OR=1.898, 95% CI 0.960-3.800, P=0.067), higher NLR value ( OR=1.313, 95% CI 0.9901.832, P=0.082) and FIB concentration ( OR=1.436, 95% CI 1.008-2.125, P=0.056) might have potential association with MID. Stepwise regression method was used to screen out PLT, FIB and hydronefrosis as the optimal combination for MID prediction. multivariate analysis suggested that PLT decreasing ( OR=0.727, 95% CI 0.548-0.955, P=0.023), FIB increasing ( OR=1.629, 95% CI 1.084-2.552, P=0.025) and hydronephrosis ( OR=2.500, 95% CI 1.111-5.601, P=0.026) were independent predictors of MID.The C-index of the model constructed by the three factors was 0.682, and the P-value of the goodness of fit was 0.778. The ROC curve showed that the optimal cut-off point for the prediction of high-risk MID by the nomogram was 0.627, achieving 39.1% specificity, 88.6% sensitivity and 0.682 area under the curve (AUC). Conclusions:Preoperative decrease of PLT, increase of FIB and hydronephrosis were independent factors for predicting UTUC invading muscle.

Objective:To analyze the clinical and laboratory characteristics of acute myeloid leukemia (AML) patients with NPM1 mutation, and to explore the prognostic factors.Methods:A total of 77 AML patients with NPM1 gene mutation admitted to Hebei Yanda Ludaopei Hospital from May 1st 2012 to December 31st 2021 were enrolled in the study, including 34 male and 43 female patients. The median age was 40 (3, 68) years old. Patients were selected and divided into 4 groups according to the morphological FAB classification. There were 29 cases (37.7%) of M1 type, 13 cases (16.9%) of M2 type, 23 cases (29.9%) of M4 type, and 12 cases (15.5%) of M5 type. The clinical characteristics, bone marrow/peripheral blood cell morphology, immunophenotype, cytogenetics, molecular biology and overall survival of different groups were retrospectively analyzed, and the risk factors affecting the prognosis of AML were also explored. Cox multivariate regression was used to analyze the clinical influencing factors of survival and prognosis.Results:The white blood cell counts were highest in M4 and M5 patients and lowest in M2 patients, while no significant difference in the red blood cell, hemoglobin, and platelet counts( P>0.05). Morphologically, there were significant differences in the percentage of blasts and blasts with cup-like nuclei on bone marrow (BM) and peripheral blood (PB). The proportion of blasts in BM and PB was the highest in M1 and the lowest in M2 ( P<0.001). The positive rate of blasts with cup-like nuclei was the highest in M1 and the lowest in M5 of BM ( P<0.001), while the highest in M2 and the lowest in M5 of PB ( P=0.006). The scores of myeloperoxidase and chloroacetate esterase were all the highest in M1 and the lowest in M5 ( P<0.001, 0.001, respectively). In terms of molecular biology, the occurence rate of blasts combined with DNMT3A mutation was the highest in M4 and the lowest in M2 ( P=0.044), while those combined with FLT3-ITD mutation was the highest in M4 and the lowest in M5 ( P=0.002). In immunophenotype, there were significant differences in the expression positivities of seven antigens including HLA-DR, CD56, CD11c, CD15, CD14, CD96 and cMPO ( P<0.05). Multivariate COX regression analysis showed that no recurrence after treatment ( P<0.001), complete remission after treatment ( P=0.015) and transplantation ( P<0.001) were correlated with overall survival (OS). No recurrence after treatment ( P=0.033), transplantation ( P=0.027), no mutation of FLT3-ITD ( P=0.040), and hemoglobin concentration ( P=0.023) were associated with relapse-free survival (RFS). Survival analysis by Kaplan-Meier curve showed that there was no significant difference in survival time between the M1, M2, M4 and M5 groups in OS and RFS. Conclusion:There were significant differences in the white blood count, the percentage of blasts and blasts with cup-like nuclear morphology, cytochemical staining (MPO integration, CE integration and percentage of NAS-DCE), gene mutation (DNMT3A and FLT3-ITD) and immunophenotypes (HLA-DR, CD56, CD11c, CD15, CD14, CD96 and cMPO) between the four groups. The multivariate analysis revealed that no recurrence after treatment and transplantation were independent prognostic factors in NPM1 mut AML patients. On the other hand, FLT3-ITD mutation and hemoglobin concentration were associated with RFS and complete remission after treatment was associated with OS in the entire NPM1 mut cohort.

Objective@#To explore the association between negative emotion (depression, anxiety and stress), family intimacy and Internet addiction, so as to provide a basis for the intervention of Internet addiction among junior and senior high school students.@*Methods@#Students were selected by stratified random cluster sampling method from junior high schools and senior high schools from December 2022 to February 2023 in Yixing City, Jiangsu Provicne. A total of 3 026 students completed the questionnaire survey, including the demographic characteristics, Depression, Anxiety and Stress Scale-21 (DASS-21), Family Environment Scale-Chinese Version (FES-CV), and Chinese Internet Addiction Scale Revised (CIAS-R). Bivariate correlation was used to analyzed the association of family intimacy, depression, anxiety, stress, and Internet addiction. Mediating effect model was used to analyzed the mediating effect of negative emotion between family intimacy and Internet addiction.@*Results@#The average score of Internet addiction among junior and senior high school students was (46.26±15.58), and there were statistical differences in the average scores of Internet addiction across different grades ( F=87.15, P <0.01). Depression ( r =0.57), anxiety ( r =0.56), stress ( r = 0.57) were positively correlated with Internet addiction, and family intimacy ( r =-0.34) was negatively correlated with Internet diction ( P <0.01). In the mediating effect model, family intimacy negatively predicted negative emotion ( β =-0.48) and Internet addiction ( β =-0.10), and negative emotion positively predicted Internet addiction ( β =0.45) ( P <0.01). Negative emotion played a partial mediating role between family intimacy and Internet addiction (the mediation value:-1.71, 95% CI =-1.96--1.49, mediation ratio:67.9%, P <0.05).@*Conclusions@#There are associations between negative emotion, family intimacy and Internet addiction among junior and senior school students. Family intimacy indirectly affects Internet addiction mainly through negative emotion. It suggests that family education is in need of attention to reduce the prevalence rate of Internet addiction among junior and senior high school students, especially family intimacy.

Objective:To assess the efficacy of different modes of high-flow nasal cannula (HFNC) oxygen therapy modes in preventing hypoxaemia during general anesthesia in obese patients without endotracheal intubation.Methods:Eighty-four American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ patients of either sex, aged 18-64 yr, with body mass index ≥ 30 kg/m 2, undergoing non-intubated general anesthesia surgery, were divided into 3 groups ( n=28 each) by a random number table method: nasal cannula oxygen therapy group (NC group), HFNC oxygen therapy full-course non-pure oxygen group (HFNC1 group) and HFNC oxygen therapy half-course non-pure oxygen group (NHFC2 group). NC group received oxygen through bilateral nasal cannula, and the oxygen flow rate was 5 L/min, and the oxygen flow rate remained unchanged after anesthesia induction. In NHFC1 group, the flow rate was 30 L/min and the FiO 2 was 41%, and the flow rate was adjusted to 60 L/min after anesthesia induction, and the FiO 2 remained unchanged. NHFC2 group received HFNC oxygen inhalation with a flow rate of 30 L/min and FiO 2 100%, and the flow rate was adjusted to 60 L/min and FiO 2 41% after anesthesia induction. Sufentanil 0.1 μg/kg was intravenously injected after 3 min of oxygen pre-inhalation and target effect-site concentration of propofol was 4 μg/ml in open-loop TCI mode, the closed-loop mode was used to continue intravenous infusion of propofol when the BIS value reached 60 with the same target effect-site concentration, and the intraoperative BIS value was maintained at 45-60. The occurrence and total duration of hypoxemia (SpO 2 <92%) and the lowest value of SpO 2 during anesthesia were recorded. Arterial blood gas analysis was performed before anesthesia induction, at 3 min of oxygen pre-inhalation and at 10 min after anesthesia, and PaO 2 and PaCO 2 were recorded. Respiratory interventions and adverse events were recorded. Results:One patient was excluded due to change of anesthesion method in NC group.Compared with NC group, the incidence of hypoxemia was significantly decreased, the total duration of hypoxemia was shortened, the lowest value of SpO 2 was increased, and the usage rate of respiratory intervention methods was decreased, and PaO 2 was increased and PaCO 2 was decreased at 3 min of oxygen pre-inhalation and 10 min after anesthesia in HFNC2 group ( P<0.05), and PaCO 2 was significantly decreased at 3 min of oxygen pre-inhalation, PaO 2 was increased and PaCO 2 was decreased at 10 min after anesthesia ( P<0.05), and no significant change was found in the other parameters in HFNC1 group ( P>0.05). Compared with HFNC1 group, the incidence of hypoxemia was significantly decreased, the total duration of hypoxemia was shortened, the lowest value of SpO 2 was increased, the usage rate of respiratory intervention methods was decreased, and PaO 2 was increased at 3 min of oxygen pre-inhalation in HFNC2 group ( P<0.05). There was no significant difference in adverse events between the three groups ( P>0.05). Conclusions:HFNC in the mode of FiO 2 100% during oxygen pre-inhalation and FiO 2 41% during anesthesia maintenance can reduce the occurrence of hypoxemia during general anesthesia in obese patients without intubation.

Résumé
Animal experiments play an important role in the process of biomedical research, and is a necessary way to transform basic medicine into clinical medicine. The standardization of animal experimental studies and reports determines the reliability and reproducibility of research results, and is also the key to transforming the results of animal experiments into clinical trials. In view of how to design and implement animal experiments, write animal experiment reports, and publish relevant academic papers in a more standardized way, LACM (Laboratory Animal and Comparative Medicine) has launched a new column of comparative medical research and reporting standards from 2023, focusing on the introduction and interpretation of international general norms related to laboratory animal and comparative medicine, such as ARRIVE 2.0 guidelines (Animal Research: Reporting of In Vivo Experiments). This article focuses on the development and application, basic content and priority of ARRIVE 2.0, as well as the scheme of implementing ARRIVE 2.0 guidelines in international biomedical journals, and explains the current situation and future plans of LACM following ARRIVE 2.0 guidelines. The research and report of animal experimental medicine following the ARRIVE 2.0 guidelines and other international norms is one of the important driving forces to promote the high-quality development of experimental animal science and biomedicine in China, and also a powerful means to implement the 3R principle and improve the welfare of laboratory animals. Through this article, we hope the majority of scientific researchers and editors will attach great importance and actively implement these international standards.
Résumé
Objective:To investigate the effectiveness of nasal endoscopic anterior lacrimal recess approach combined with temporary fenestration of the nasal septum in resecting recurrent nasal inverted papilloma. Methods:Patients with recurrent nasal inverted papilloma who underwent reoperation in our hospital during the past 2 years were included . The nasal septum may hinder full access to and effective treatment of the lesions at the anterior and medial wall of the maxillary sinus by endoscope, aspirator and surgical instrument in the narrow aperture of the prelacrimal recess, although these lesions could be observed by 70° nasal endoscope. Results:The nasal septum is temporarily opened on the basis of the prelacrimal recess approach, and the nasal endoscope and instrument was introduced through trans-septal window, so as to provide a better view of the operative field and the angular range of the instrument's movement. Conclusion:The recurrent nasal inverted papilloma could be successfully managed by re-endoscopic anterior lacrimal recess approach combined with temporary fenestration of the nasal septum, and no recurrence was observed during the 2-year follow-up. This surgical approach is recommended for the inverted papilla which originates from the anterior medial wall of the maxillary sinus, as the tumor can be removed completely using this surgical approach.

Objective:To analyze clinical data of 3 children with LMX1B-associated disease characterized by asymptomatic glomerular proteinuria, thus improving the recognition of asymptomatic proteinuria with genetic causes. Methods:Three patients with LMX1B-associated disease presented with prominent asymptomatic proteinuria diagnosed by the next-generation sequencing in Department of Pediatrics, Peking University First Hospital from April 2014 to October 2017 were included in this study.Clinical data, including renal and extrarenal manifestations, renal biopsy, and family history, were collected and retrospectively analyzed. Results:All 3 children were girls, the age of onset were 2 years, 1 year, and 4 years, respectively, and the diagnosis age were 11 years, 5 years and 6 years, respectively.All of them had glomerular proteinuria, and nephrotic-level proteinuria occurred in one patient.Microscopic hematuria was found in 2 patients.All of them had normal renal function.Only one patient underwent renal biopsy.Electron microscopy of the first time of biopsy revealed segmental thinning of the glomerular basement membrane.Re-biopsy 4 years later showed irregular thickening of the glomerular basement membrane, moth-eaten appearance and collagen fibrillar material deposition.No abnormalities of nails, limbs and joints were observed by physical examination.Two patients had a family history of renal disease.Conclusions:Genetic factors should be considered in children with obscure onset asymptomatic proteinuria without definite clinical causes.Genetic testing can help diagnose and guide treatment as early as possible.
