ObjectiveTo observe the clinical effect of Jieyu Qingxin formula granules combined with remote interactive cognitive behavioral therapy for insomnia （CBT-I） on chronic insomnia of liver depression and fire-turning type. MethodThis study was a prospective randomized controlled trial. 120 patients with chronic insomnia of liver depression and fire-turning type in Lu'an traditional Chinese medicine Hospital from January 2022 to June 2023 were selected as objects. They were randomly divided into two groups，with 60 cases in each group. The control group received remote interactive CBT-I. The observation group was treated with Jieyu Qingxin formula granules on the basis of the control group. Intervention treatment lasted for four weeks，and observation lasted for six weeks. Comparison of data of each group：clinical efficacy，changes in traditional Chinese medicine （TCM） syndrome score before and after treatment，changes in insomnia severity index （ISI） score，self-rating depression scale （SDS） and self-rating anxiety scale （SAS） score changes，total sleep time，wake time，sleep latency，sleep efficiency， Actigraphy sleep parameter value changes，serum neuron specific enolase （NSE） ，adenosine，dopamine （DA）， 5-hydroxytryptamine （5-HT） level changes，and adverse reactions. ResultThe total effective rate in the observation group （92.45%，49/53） was higher than that in the control group（76.92%，40/52）， and the difference was statistically significant（χ²=4.711 1，P<0.05）. After treatment，TCM syndrome score，ISI score，SAS score， and SDS score were decreased in all groups. The total sleep time was extended，and wake time and sleep latency were shortened. The sleep efficiency was increased，but the NSE and DA levels were decreased. Adenosine and 5-HT levels were increased in all groups（P<0.05）. After treatment，compared with the control group，the observation group had lower TCM syndrome score，ISI score，SAS score， and SDS score，longer total sleep time，higher sleep efficiency，shorter wake time and sleep latency，lower NSE and DA levels， and higher adenosine and 5-HT level （P<0.05）. There was one case of nausea in the observation group and no adverse reaction in the control group during treatment. There was no significant difference between the two groups. ConclusionBy reducing NSE and DA and increasing the levels of 5-HT and adenosine，the anxiety （SAS score） and depression （SDS score） of patients can be improved， so as to improve their sleep and effectively treat chronic insomnia of liver depression and fire-turning type.

Objective:To analyze the epidemiological and clinical characteristics of respiratory syncytial virus (RSV) infection in children in Jiangsu Province from 2014 to 2023.Methods:The acute respiratory infection cases in children aged 0-14 years were selected from outpatient/emergency or inpatient departments in 2 surveillance sentinel hospitals, respectively, in Nanjing, Suzhou and Taizhou of Jiangsu from 1 July 2014 to 31 December 2023, and RSV nucleic acid test was conducted and the intensity of the RSV infection was accessed by WHO influenza epidemiological threshold method, and case information and clinical data were collected. χ2 test was used to compare the differences between groups, and the Bonferroni method was used for pairwise comparisons between groups. Results:In 4 946 cases of acute respiratory infections, the RSV positive rate was 8.21% (406/4 946), and the age M( Q1, Q3) of the cases was 1 (0, 3) years. The RSV positive rate was 10.92% (258/2 362) during 2014-2019 and 6.06% (118/1 948) during 2019-2023, the difference was significant ( χ2=31.74, P<0.001). RSV infection mainly occurred from October to March during 2014-2019, with the incidence peak in December and moderate or higher intensity. The seasonality of RSV infection was not obvious during 2019-2023, with low intensity. The RSV positive rate was highest in children in age group 0- years (17.85%, 151/846), and the positive rate declined gradually with age ( χ2=184.51, P<0.001). The RSV positive rate was higher in inpatient cases (9.84%, 244/2 480) than in outpatient/emergency cases (6.57%, 162/2 466) ( χ2=17.54, P<0.001). In the 155 RSV infection cases with complete clinical data, the clinical symptoms mainly included cough (99.35%, 154/155), fever (55.48%, 86/155), and shortness of breath (45.16%, 70/155). In the cases aged <6 months, the proportion of those with fever was low, but the proportion of those with shortness of breath, transferred to intensive care units, and receiving oxygen therapy were higher (all P<0.05). Children aged <6 months and those with underlying diseases were more likely to have severe RSV infection (all P<0.05). Conclusions:RSV infection in children in Jiangsu Province showed seasonal prevalence in winter from 2014 to 2019. Since 2020, the seasonal characteristics of the epidemic have changed, the epidemic period has been dispersed and the epidemic intensity has decreased. Infants <1 year old were at high risk for RSV infection, and those <6 months old and with underlying diseases might have severe infection.

Background::Growth retardation is a common complication of chronic kidney disease in children, which can be partially relieved after renal transplantation. This study aimed to develop and validate a predictive model for growth patterns of children with end-stage renal disease (ESRD) after kidney transplantation using machine learning algorithms based on genomic and clinical variables.Methods::A retrospective cohort of 110 children who received kidney transplants between May 2013 and September 2021 at the First Affiliated Hospital of Zhengzhou University were recruited for whole-exome sequencing (WES), and another 39 children who underwent transplant from October 2021 to March 2022 were enrolled for external validation. Based on previous studies, we comprehensively collected 729 height-related single-nucleotide polymorphisms (SNPs) in exon regions. Seven machine learning algorithms and 10-fold cross-validation analysis were employed for model construction.Results::The 110 children were divided into two groups according to change in height-for-age Z-score. After univariate analysis, age and 19 SNPs were incorporated into the model and validated. The random forest model showed the best prediction efficacy with an accuracy of 0.8125 and an area under curve (AUC) of 0.924, and also performed well in the external validation cohort (accuracy, 0.7949; AUC, 0.796). Conclusions::A model with good performance for predicting post-transplant growth patterns in children based on SNPs and clinical variables was constructed and validated using machine learning algorithms. The model is expected to guide clinicians in the management of children after renal transplantation, including the use of growth hormone, glucocorticoid withdrawal, and nutritional supplementation, to alleviate growth retardation in children with ESRD.

Objective:To explore the clinical characteristics of pediatric kidney transplant recipients reinfected with SARS-CoV-2.Method:The relevant clinical data were retrospectively reviewed for 191 pediatric kidney transplant recipients at a single center. Based upon whether or not there was a reinfection of SARS-CoV-2, they were assigned into two groups of single infection (group A, 127 cases) and reinfection (group B, 64 cases). Baseline profiles, clinical symptoms, diagnostic and therapeutic strategies, markers of disease progression, immune status, respiratory support modalities, comorbidities and transplantation-related data were collected for comparing the inter-group differences during primary infection and between two infections in reinfected group.Result:As compared with group A, group B recipients had a higher proportion of age <12 years (71.9% vs 54.3%) ,unvaccinated (81.2% vs 66.1%) and such symptoms as high fever (34.4% vs 12.6% ), dry cough (43.8% vs 23.6% ) and chest tightness (14.1% vs 3.9 %) during primary infection (all P<0.05). During primary infection, the levels of IL-6 and CRP were higher in group B than in group A and inter-group difference was statistically significant (both P<0.01). The levels of IL-6 ( P<0.01), CRP ( P<0.01) and PCT ( P= 0.023) were lower in group B during reinfection than those during primary infection and the difference was statistically significant. During primary infection, the counts of CD3+, CD4+, CD8+, NK and B lymphocyte of group B were lower than those of group A. And inter-group differences were statistically significant (all P<0.01). During reinfection, the levels of CD3+, CD4+, CD8+, NK and B lymphocyte counts of group B spiked as compared with those of group A during primary infection and the differences were statistically significant (all P<0.01). The levels of SCr and UA in group B differed insignificantly before and after primary infection with SARS-CoV-2. However, the differences before and after reinfection were statistically significant (both P<0.01) . Conclusion:Symptomatic and immunocompromised pediatric KT recipients during primary infection with SARS-CoV-2 are more prone to reinfection during subsequent epidemics. Though mildly symptomatic, reinfection may exacerbate impairments of graft kidney function in pediatric KT recipients.

Objective:To explore the characteristic pathological manifestations of non-HLA antibodies after kidney transplantation (KT) and examine the differences of MFT values of non-HLA antibodies in different pathological manifestations.Methods:The study was conducted on KT recipients at the First Affiliated Hospital of Zhengzhou University from February 2021 to June 2023 with unexplained elevated serum creatinine. Patients undergoing pathological puncture and concurrent HLA antibody testing were included, focusing on those with DSA (MFI>4 000) and non-HLA antibody negativity. According to the detection results of non-HLA and HLA antibodies, they were assigned into two groups of non-HLA antibody positive (45 cases) and HLA-DSA positive (28 cases). Both non-HLA and HLA antibodies were detected by luminex single antigen microbeads, χ2, t or Mann-Whitney U nonparametric tests were utilized for examining the inter-group differences in pathological manifestations. The recipients with positive non-HLA antibodies were grouped according to the differential pathological features[microvascular inflammation group (22 cases) and non-microvascular inflammation group (23 cases), interstitial fibrosis group (39 cases) and non-interstitial fibrosis (9 cases) ]. MFI values of non-HLA antibodies were standardized and heat map was generated with R language ComplexHeatmap package. The differences of response values of non-HLA antibodies with different pathological manifestations were examined by rank-sum test. Results:The positive rates of microvascular inflammation were 48.9% (22/45) and 82.1% (23/28) in HLA-DSA positive and non-HLA antibody positive groups with statistical significance ( χ2=8.073, P=0.006). The positive rates of interstitial fibrosis in two groups were 80.8% (36/45) and 53.6% (15/28) and the difference was statistically significant ( χ2=5.726, P=0.021). The relative levels of anti-arachnotoxin receptor 1 (Latrophilin 1, LPHN1), keratin 8 (KRT8), keratin 18 (KRT18) and Sjogren's syndrome antigen B (SSB) were higher in microvascular inflammation group than those in non-microvascular inflammation group. The differences were statistically significant [559.50 (262.00, 801.25) vs 285.00 (183.00, 460.00), P=0.024; 504.50 (369.5, 725.25) vs 317.00 (231.50, 458.00), P=0.014; 672.50 (454.50, 969.50) vs 399.00 (246.50, 772.50), P=0.030; 967.50 (482.00, 2 066.50) vs 399.00 (246.50, 772.50), P=0.033]. The relative levels of anti-cyclic citrullinate peptide (CCP), colony-stimulating factor 2 (CSF2), intercellular adhesion molecule 1 (ICAM1) and collagen Ⅳ antibody were higher in interstitial fibrosis group than those in non-interstitial fibrosis group with statistical significance [100.00 (79.88, 167.50) vs 64.50 (37.00, 89.00), P=0.016; 146.25 (93.38, 244.75) vs 87.00 (66.00, 105.00), P=0.041; 132.50 (106.38, 229.50) vs 95.00 (55.00, 125.00), P=0.037; 432.50 (280.75, 653.75) vs 208.00 (192.00, 301.00), P=0.028]. Conclusions:As compared with HLA-DSA, the characteristic pathological manifestations of non-HLA antibodies post-KT include a lower incidence of microvascular inflammation and a higher incidence of interstitial fibrosis. For non-HLA antibody response values of characteristic pathological manifestations, the expressions of different non-HLA antibodies vary statistically.

Hereditary nephrotic syndrome (NS) has a high risk of progression to end-stage renal disease.Renal transplantation is the optimal renal replacement therapy.The specificity of hereditary NS in the field of kidney transplantation has not been systematically illustrated yet.Due to the large amount of hormone uses before operation, the difference of immunosuppressive therapy in patients with hereditary NS should be well concerned, including the selection of immune induction and maintenance regimens.Relatives of patients with hereditary NS should undergo genetic testing before living donor transplantation, and donors are qualified only after a thorough risk assessment and informed consent.Post-transplant recurrence of hereditary NS is rare, with an acceptable response to plasma exchange.This review aims to describe the characteristics of hereditary NS in children in the field of kidney transplantation, thus providing guidance for kidney transplantation for hereditary NS.

Objective:To explore the efficacy and safety of low-dose rabbit anti-human thymocyte globulin (rATG) for induction therapy of kidney transplantation (KT) in children.Methods:From October 2018 to May 2021, clinical data were reviewed retrospectively for 77 pediatric KT recipients on a low-dose rATG induction protocol.Recipient/graft survival rate, renal function recovery, acute rejection (AR) and adverse reactions were observed at 1 year post-operation.The postoperative changes of renal function were examined by Friedman’s test; According to the preoperative baseline data, Pearson’s Chi-square or Fisher's exact test was utilized for examining the influencing factors of postoperative AR.Results:A total of 16(20.78%) recipients had AR within the first 6 months post-operation.The incidence of delayed graft function (DGF) was 14.29%(11/77); The incidence of severe infection post-transplantation 18.18%(14/77), the infection rate of BK virus 25.97%(20/77) and the incidence of neutropenia 32.47%(25/77).The recipient/graft survival rate at 1 year post-operation was 97.40%(75/77) and 94.81%(73/77) respectively.Chi-square test indicated that the incidence of postoperative infection in children with body weight ≤30 kg and height ≤138 cm was 28.95%(11/38) and 27.50%(11/40) respectively, Both were higher than 7.69%(3/39) and 8.11%(3/37) of children with body weight >30 kg and height>138 cm.The difference between groups was statistically significant ( P=0.016 and 0.028). Conclusions:Low-dose rATG is generally excellent in preventing AR in pediatric KT recipients.And the risk of related AR may be lower.The infection rate of recipients with decent preoperative development is low.

Objective:To translate the University of Rhode Island Change Assessment of voice scale（URICA-Voice） into Chinese and test its reliability and validity. Methods:The URICA-Voice scale was converted into Chinese by literal translation, cultural adjustment, expert consultation, pre-investigation, and back translation. Convenience sampling was used to recruit patients at four speech therapy centers from February to May 2022. Then the Chinese version of the scale was distributed to them, and the reliability and validity of the scale were tested after data collection. Cronbach ɑ was used to evaluate the reliability. The critical ratio method and Pearson correlation coefficient were used for item analysis. Item-level content validity, scale-level content validity, and confirmatory factor analysis were used to test the validity of the scale. Results:A total of 247 valid questionnaires were collected. ①Item analysis: the critical ratios between a high-score and low-score groups of 32 items were all statistically significant（P<0.01） and all the critical ratios were above 3.00. The Pearson correlation between 32 items and the total score was significant（P<0.01）. ②Validity analysis: I-CVI=1.00, S-CVI/Ave=1.00, χ²/df=2.30, RMSEA=0.07. Except for item 9 and 23, the standardized factor loading coefficients of other items were all above 0.50. AVE of the four dimensions of the scale was all above 0.50, and the combined reliability of the four dimensions was all above 0.70. The correlation coefficients between dimensions were less than the square root of the AVE of the dimension itself. ③Reliability analysis: the Cronbach ɑ of the whole scale was 0.94, and the Cronbach ɑ of the four dimensions were 0.88, 0.92, 0.94, and 0.88 respectively. Conclusion:The Chinese version of URICA-Voice has good reliability and validity, and can be used as a specific measurement tool for evaluating the compliance of voice training in China.

Objective:Currently,patients with pre-exsiting donor-specific antibody(DSA)are prone to antibody-mediated rejection(AMR)after surgery and are at a relatively high risk of postoperative complications and graft failure.The risk of postoperative complications and graft failure is relatively high.This study aims to discuss the clinical outcome of DSA-positive kidney transplantation and analyze the role and safety of preoperative pretreatment in DSA-positive kidney transplantation,providing single-center treatment experience for DSA-positive kidney transplantation. Methods:We retrospectively analyzed the clinical data of 15 DSA-positive kidney transplants in the Department of Renal Transplantation of First Affiliated Hospital of Zhengzhou University from August 2017 to July 2022.Eight cases were organ donation after citizen's death(DCD)kidney transplant recipients,of which 3 cases in the early stage were not treated with preoperative desensitisation therapy(DCD untreated group,n=3),and 5 recipients were treated with preoperative rituximab desensitisation(DCD preprocessing group,n=5).The remaining 7 cases were living related donors recipients(LRD)who received preoperative desensitisation treatment with rituximab and plasma exchange(LRD preprocessing group,n=7).We observed and recorded the incidence of complications with changes in renal function and DSA levels in the recipients and the survival of the recipients and transplanted kidneys at 1,3 and 5 years,and to compare the differences in recovery and postoperative complications between 3 groups. Results:All 15 recipients were positive for preoperative panel reactive antibody(PRA)and DSA and were treated with methylprednisolone+rabbit anti-human thymocyte immunoglobulin induction before kidney transplantation.DCD untreated group all suffered from DSA level rebound,delayed renal graft function(DGF)and rejection reaction after surgery.After the combined treatment,DSA level was reduced and the graft renal function returned to normal.The DCD preprocessing group were all without antibody rebound,1 recipient developed DGF and the renal function returned to normal after plasmapheresis,and the remaining 4 recipients recovered their renal function to normal within 2 weeks after the operation.In the LRD preprocessing group,2 cases had antibody rebound and 1 case had rejection,but all of them recovered to normal after treatment,and DSA was maintained at a low level or even disappeared.The incidence of DGF and rejection in the DCD untreated group were significantly higher than that in the DCD preprocessing group and the LRD preprocessing group;and there were no significant difference in the incidence of postoperative haematuria,proteinuria,bacterial and fungal infections,and BK virus infection between the 3 groups(all P>0.05).A total of 11 of the 15 recipients were followed up for more than 1 year,6 for more than 3 years,and 1 for more than 5 years,and the survival rates of both the recipients and the transplanted kidneys were 100%. Conclusion:Effective preoperative pretreatment with desensitization therapy can effectively prevent antibody rebound in DSA-positive kidney transplantation and reduce perioperative complications.

Objective To investigate the exposure difference of different dosage forms of mycophenolic acid (MPA) between children aged ≤12 and > 12 years old after kidney transplantation. Methods Clinical data of 73 children undergoing kidney transplantation from donation after cardiac death (DCD) were retrospectively analyzed. Postoperative immunosuppressive regimen was MPA+ tacrolimus+glucocorticoid. According to different dosage forms of MPA, all recipients were divided into group A (n=37, mycophenolate mofetil capsules), group B (n=28, enteric-coated mycophenolate sodium) and group C (n=8, mycophenolate mofetil dispersible tablets). All children were divided into ≤12 and > 12 years old groups according to the age of kidney transplantation. The daily dosage of different dosage forms was calculated. The blood concentration (C) of MPA and the area under the curve (AUC) were detected by enzyme-multiplied immunoassay technique. The MPA blood concentration was statistically compared between two age groups at different time points. The recovery of renal function and postoperative complications were assessed. Results No significant differences were observed in the dosage and blood concentration of drug at different time points among groups A, B and C (all P > 0.05). The MPA-C_{4 h} and AUC in the ≤12 years old group were significantly higher than those in the > 12 years old group (both P < 0.05). In group B, the MPA-C_{4 h} of children aged ≤12 years old was significantly higher compared with that in those aged > 12 years old (P=0.016). The MPA-C_{4 h} of children aged ≤12 years old in group B was higher than those in group A and group C, but the differences were not statistically significant (P=0.080). There was no significant difference in the incidence of acute rejection and infection among three groups (both P > 0.05). Conclusions Children of different ages who are given with different dosage forms of MPA after kidney transplantation obtain different exposure rates. The exposure rate of kidney transplant recipients aged ≤12 years old tends to be higher than that of their counterparts aged > 12 years old, mainly seen in the recipients treated with enteric-coated mycophenolate sodium. Therefore, it is necessary to monitor the exposure level of MPA, which provides significant guidance for adjusting the drug dosage of different dosage forms.
