ObjectiveTo analyze the clinical treatment plan and traditional Chinese medicine （TCM） medication rule of children with primary nephrotic syndrome （PNS） in the First Affiliated Hospital of Henan University of Chinese Medicine. MethodsThe gender and age of children firstly diagnosed with nephrotic syndrome in the pediatric nephrology department of the First Affiliated Hospital of Henan University of Chinese Medicine from November 2019 to December 2022 were collected， and the use of immunosuppressive agents and related frequencies were counted. According to the inclusion and exclusion criteria， an independent TCM prescription database for children with nephrotic syndrome was established. Excel was used to analyze the relevant information of the literature. The frequency counting， association rule analysis， and cluster analysis were carried out on TCM in the prescription， and the high-frequent drugs were analyzed. Results（1） General information： A total of 711 children were included， consisting of 522 males （73.42%） and 189 females （26.58%）. The ratio of male to female was about 2.76∶1. The disease mainly occurred in infants and preschool age， and the average age of onset was （4.74 ± 3.48） years old. （2） Clinical treatment plan and use of immunosuppressive agents： Of the 711 children with PNS， 237 were treated with hormone alone （32.33%）， and 474 （66.67%） received immunosuppressive agents combined with hormones. In the initial treatment， hormone combined with Tacrolimus （TAC） was the preferred treatment （32.91%）. For children with refractory PNS who exhibited poor clinical efficacy， Rituximab （RTX） was mostly used for treatment， with a ratio of up to 23.63%. （3） TCM syndrome and medication rule： In PNS syndrome differentiation， Qi and Yin deficiency was identified as the main syndrome. This involved a total of 477 cases， accounting for 67.09%. Yang deficiency of spleen and kidney was observed in 118 cases， accounting for 16.60%. A total of 711 children were included， of which 706 children were treated with TCM. This involved a total of 706 prescriptions， 226 TCM， and 9 793 frequencies. There were 30 herbs used more than 95 times. The top five TCM were Radix et Rhizoma Glycyrrhizae （81.16%）， Radix Astragali （71.81%）， Poria （68.84%）， Rhizoma Atractylodis Macrocephalae （63.60%）， and Fructus Corni （57.37%）. The drug association rules and network diagram showed that the combination of ''Radix Astragali-Rhizoma Atractylodis Macrocephalae-Poria'' was the closest， and five types of combinations were obtained by cluster analysis. ConclusionIn the diagnosis and treatment of PNS in children， TAC combined with hormones shows good clinical efficacy and high safety. For children with refractory PNS， RTX combined with hormones can be used. TCM medication for PNS should follow the basic principles of strengthening the body and vital Qi and make good use of drugs such as Radix Astragali， Poria， Rhizoma Atractylodis Macrocephalae， and cornus to regulate the Yin and Yang balance and achieve better clinical efficacy.

ObjectiveTo determine the syndrome of a rat model of follicular dysplasia induced by Tripterygium glycosides based on prescriptions and investigate the mechanism of traditional Chinese medicine intervention via the adenosine monophosphate-activated protein kinase （AMPK）/mammalian target of rapamycin （mTOR）/hypoxia-inducible factor-1 （HIF-1）/vascular endothelial growth factor （VEGF） pathway. MethodForty-eight rats with regular estrous cycles were randomly assigned into a normal group （n=8） and a modeling group （n=40）. The rats in the modeling group were administrated with Tripterygium glycoside suspension （75 mL·kg^-1） by gavage for 30 days. The modeled rats were assigned into model， Siwutang （3.69 g·kg^-1）， Youguiyin （3.11 g·kg^-1）， Zuoguiyin （7.29 g·kg^-1）， and Guishenwan （10.35 g·kg^-1） groups， with 8 rats in each group. The drug intervention lasted for 14 days. The changes of estrous cycle were detected by Pap staining， and a stereoscope was used to observe the morphology of the ovarian tissue. Hematoxylin-eosin staining was employed to observe the pathological changes and follicle count in the ovarian tissue. Enzyme-related immunosorbent assay （ELISA） was used to measure the levels of follicle-stimulating hormone （FSH）， luteinizing hormone （LH）， and estradiol （E₂） in the serum. Real-time fluorescence quantitative polymerase chain reaction and Western blot were employed to determine the mRNA and protein levels， respectively， of AMPK， mTOR， HIF-1， and VEGF in the ovarian tissue. ResultCompared with the normal group， the model group had a disordered estrous cycle， reduced secondary and mature follicles， increased atretic follicles， elevated FSH and LH levels， lowered E₂ level， up-regulated mRNA and protein levels of AMPK， and down-regulated mRNA and protein levels of mTOR， HIF-1， and VEGF （P<0.01）. Compared with the model group， Guishenwan increased secondary and mature follicles， decreased atretic follicles， lowered the FSH and LH levels， elevated the E₂ level， down-regulated the mRNA and protein levels of AMPK， and up-regulated the mRNA and protein levels of mTOR， HIF-1， and VEGF （P<0.01）. Compared with Guishenwan group， Siwutang， Youguiyin， and Zuoguiyin decreased mature follicles， increased atretic follicles （P<0.01）， elevated the LH （P<0.01） and FSH （P<0.05） levels， and lowered the E₂ level （P<0.05）. In addition， Youguiyin up-regulated the protein level of AMPK （P<0.05） and down-regulated the mRNA levels of mTOR and HIF-1 （P<0.01） as well as the mRNA and protein levels of VEGF （P<0.01）. Siwutang down-regulated the mRNA levels of mTOR and HIF-1 as well as the mRNA and protein levels of VEGF （P<0.05）. Zuoguiyin down-regulated the mRNA level of mTOR and the protein and mRNA levels of VEGF （P<0.05）. ConclusionGuishenwan may improve the ovarian function and promote follicle maturation in a rat model of follicular dysplasia by inhibiting the AMPK/mTOR/HIF-1/VEGF pathway， with the therapeutic effect superior to Zuoguiyin， Youguiyin， and Siwutang. It was hypothesized that this model presented the syndrome of kidney-essence deficiency.

Objective:To investigate the application value of optical coherence tomography (OCT) and intravascular ultrasound (IVUS) in evaluating flow diverter (FD) apposition and endothelialization in aneurysm animal models, and analyze the effect of incomplete stent apposition (ISA) on aneurysm lumen healing and stent endothelialization.Methods:Lateral common carotid artery aneurysm models in swines were established by surgical method and then FD was implanted. Immediately after surgery, OCT and IVUS were used to evaluate the locations and degrees of ISA, and difference between these 2 methods in evaluating FD apposition was compared. DSA was performed at 12 weeks after surgery to evaluate the aneurysm occlusion (Kamran grading) and stent patency. OCT and IVUS were used again to observe the stent endothelial situation; by comparing with histopathologic results, effect of ISA on aneurysm healing and stent endothelialization was analyzed.Results:Lateral common carotid artery aneurysm models in 6 swines were established, and 6 Tubridge FDs were successfully implanted. Compared with IVUS (3 stents, 4 locus), OCT could detect more ISA (6 stents, 14 locus); and the vascular diameter change area (7 locus), aneurysm neck area (4 locus) and the head and tail of FD (3 locus) were the main sites of FD malapposition; average distance between stent wire and vessel wall was (560.14±101.48) μm. At 12 weeks after surgery, DSA showed that 1 patient had a little residual contrast agent at the aneurysm neck (Kamran grading 3), and the remaining 5 had complete aneurysm occlusion (Kamran grading 4). One FD had moderate lumen stenosis, and the other 5 FDs had lumen patency. OCT indicated mostly disappeared acute ISA; ISA proportion decreased to 21.4 % (3/14), including 2 in the aneurysm neck and 1 in the partial stent. Histopathological results showed bare stent woven silk, without obvious endothelial coverage; in one FD with luminal stenosis, intimal hyperplasia was mainly composed of vascular smooth muscle cells.Conclusion:In carotid artery aneurysm model with FD implantation, OCT can detect more ISA than IVUS; most acute ISA have good outcome at 12 th week of follow-up, while severe ISA can cause delayed FD endothelialization and delayed aneurysm occlusion.

Objective:To investigate the effect of dexamethasone mixed with ropivacaine for cervical nerve pathway blockade on the postoperative swallowing function in patients undergoing thyroid surgery.Methods:This was a prospective randomized controlled trial. One hundred twenty-four patients, regardless of gender, aged 18-60 yr, of American Society of Anesthesiologists Physical Status classification Ⅰor Ⅱ, who underwent elective thyroidectomy at Xuzhou Cancer Hospital from March to December 2023, were selected and divided into test group (DR group, n=62) and control group (R group, n=62)using a random number table method. After induction of total intravenous anesthesia, bilateral cervical nerve pathway blockade was performed, dexamethasone 5 mg and 0.25% ropivacaine 10 ml were injected in DR group, and 0.25% ropivacaine 10 ml was injected in group R. Main outcome measures: The swallowing function was assessed using Standard Swallowing Assessment scale at 1 and 6 days postoperatively, and the occurrence of swallowing dysfunction (abnormal in any indicator) was recorded. Secondary outcome measures: numerical rating scale scores were recorded immediately after tracheal extubation and at 4, 8, 12, 24 and 48 h after tracheal extubation in both static and swallowing states. Voice function was evaluated using the Voice Handicap Index-10 at 1 and 6 days postoperatively. The use of ketorolac tromethamine and occurrence of adverse reactions after surgery were recorded. Results:Sixty-one patients were finally included in DR group and 60 patients in R group. Compared with R group, the Standard Swallowing Assessment scale scores at 1 and 6 days after operation and incidence of swallowing disorders at 1 day after operation were significantly decreased, the numerical rating scale scores at 8 and 12 h after tracheal extubation in the static state and at 4-24 h after tracheal extubation in the swallowing state were decreased, the incidence of postoperative nausea and vomiting and Voice Handicap Index-10 scores at 1 day after operation were decreased, and the number of patients who used ketorolac tromethamine was reduced in DR group ( P<0.05). Conclusions:Dexamethasone mixed with ropivacaine for cervical nerve pathway blockade can improve the postoperative swallowing function in patients undergoing thyroid surgery.

Objective To explore the regulation of Chaihuang Qingyi Huoxue Granule on intestinal microecological changes in rats with severe acute pancreatitis (SAP) and the potential mechanism for its treatment of SAP. Methods Forty-eight rats were randomly divided into sham operation group (SHAM),SAP model group (SAP),and Chaihuang Qingyi Huoxue Granule (CH)group,with 16 rats in each group. Each group was further divided into 12 h and 24 h subgroups. The SAP model was induced by retrograde injection of 5％ sodium taurocholate into the pancreaticobiliary duct through duodenal wall. The SHAM and SAP groups received normal saline by gavage,while the CH group received 1.2 g·kg-1 Chaihuang Qingyi Huoxue Granule solution by gavage every six hours. At 12 h and 24 h after operation,eight rats from each group were sacrificed to collect abdominal aortic blood,pancreatic and ileal tissues for analysis. Ascites,pancreatic and ileal tissues were observed. Serum amylase(AMY) and lipase (LPS) levels were measured biochemically. Pathological changes in pancreatic and ileal tissues were investigated by HE staining. Claudin-1 protein expression in ileal tissue was detected by Western Blot. Changes in the intestinal flora of ileocecal contents were analyzed by 16S rDNA high-throughput sequencing. Results Compared to the SHAM group at the same time points,the SAP group exhibited extensive pancreatic edema and necrosis. Serum AMY and LPS levels,pancreatic and ileal histopathological scores increased,and Claudin-1 protein expression in ileal tissue markedly decreased (all P<0.05). The differences in abundance of microbial community increased,while the evenness of community composition reduced. The microbial richness showed no significant change (P>0.05),but the microbial diversity decreased(P<0.05). Proteobacteria were dominant intestinal bacteria. Relative abundances of Oscillospira,Ruminococcus,Bifidobacterium,and Bacteroides S24-7 decreased,whereas relative abundances of Shigella and Allobaculum increased. The differences in abundance of microbial community reduced,and the evenness of community composition increased. The microbial richness showed no significant change(P>0.05),but the microbial diversity increased (P<0.05). Firmicutes and Bacteroidetes were the dominant intestinal bacteria. Relative abundances of Oscillospira,Ruminococcus,Bifidobacterium,and Bacteroides S24-7 increased,whereas relative abundances of Shigella and Allobaculum decreased. After the intervention of CH,pathological damage in ileal tissue was improved. The expression of Claudin-1 protein in the intestinal mucosal barrier increased compared to the model group(P<0.05). The differences in abundance of microbial community reduced,and the evenness of community composition increased. CH group showed an increase in some beneficial bacteria and decrease in pathogenic bacteria compared to model group. Conclusion Chaihuang Qingyi Huoxue Granule may reduce pancreas injury in rats with SAP,which may be involved in modulating the intestinal microecology and improving intestinal mucosal barrier function.

OBJECTIVE To study the effect and mechanism of dihydrochromone-spliced polycyclic pyrrole-spiroepoxidole compound 3m on cutaneous squamous cell carcinoma. METHODS Using human cutaneous squamous cell carcinoma A431 and Colo-16 cells as research subjects， CCK-8 assay was used to detect the effects of different concentrations of 3m （5， 10， 20， 40， 80 μmol/L） on the proliferation of A431 and Colo-16 cells after 24， 48 and 72 hours； the median inhibitory concentration （IC50） was calculated at 48 h of treatment. A431 and Colo-16 cells were divided into control group， 3m low-concentration and high- concentration groups （15， 30 μmol/L）. After treated with relevant drugs or culture medium for 48 h， the morphological changes of cells in each group were observed by inverted microscope. Clone formation rate， migration rate and number of cell invasions， cell cycle distribution and apoptosis rate were detected. The phosphorylation， or expression of Janus kinase 2/signal transducer and activator of transcription 3 （JAK2/STAT3） signaling pathway related proteins [JAK2， STAT3， B-cell lymphocyte-2 （Bcl-2）， Bcl-2- associated X protein （Bax）]， and their mRNA expression in cells were detected. RESULTS 3m could significantly inhibit the proliferation of A431 and Colo-16 cells after treated for 24， 48， 72 h （P＜0.01）， and IC50 of them were 20.36， 23.72 μmol/L， respectively. After 48 hours of treatment， compared with control group， A431 and Colo-16 cells arranged sparsely and loosely connected in 3m low-concentration and high-concentration groups. The clone formation rate， migration rate， number of cell invasions， mRNA expressions of JAK2， STAT3 and Bcl-2， the phosphorylation of JAK2 and STAT3， protein expression of Bcl-2 were significantly decreased/weakened （P＜0.01）. Proportion of cell cycle in G2 phase， apoptosis rate， protein and mRNA expression of Bax were increased significantly （P＜0.01）； and all the above effects were in dose-dependent manner. CONCLUSIONS 3m can inhibit the proliferation， clone formation， migration and invasion abilities of cutaneous squamous cell carcinoma A431 and Colo-16 cells in a dose-dependent manner， the mechanism of which may be associated with inhibiting the activity of JAK2/STAT3 signaling pathway， and inducing cell apoptosis.

Objective:To explore the clinical efficacy of disease-modifying drug nusinersen on children with spinal muscular atrophy.Methods:The baseline and longitudinal clinical data of 15 children who were treated with nusinersen in the Children′s Hospital, Zhejiang University School of Medicine from October 2019 to October 2021 were retrospectively collected. The general data (gender, age, genotype, and clinical classification, etc.), motor function, nutritional status, scoliosis and respiratory function were analyzed. Wilcoxon rank-sum test was used for comparing multi-system conditions before and after treatment.Results:The age of 15 cases (7 males, 8 females) was 6.8 (2.8, 8.3) years, with 2 cases of type 1, 6 cases of type 2, and 7 cases of type 3 respectively, and the course of disease was 55.0 (21.0, 69.0) months. After 9.0 (9.0, 24.0) months of treatment, the motor function scale evaluations of the Hammersmith neurological examination section 2 (13.0 (7.0, 23.0) vs. 18.0 (10.0, 25.0) scores, Z=-2.67, P=0.018) of 15 children, the Hammersmith functional motor scale expanded (38.0 (18.5, 45.5) vs. 42.0 (23.0, 51.0) scores, Z=-2.38, P=0.018), and the revised upper limb module (27.0 (19.5, 32.0) vs. 33.0 (22.5, 35.5) scores, Z=-2.52, P=0.012) of children with type 2 and 3 had significantly improved. Thirteen patients achieved clinically significant motor function improvement, and 2 of them had kept stable scale scores. Subjective reports also indicated that the muscle strength and daily exercise ability of these children improved after treatment, and no serious adverse reactions were reported. Supplemented by the multi-disciplinary team management, the levels of some indicators such as Cobbs angle of scoliosis and forced vital capacity all had significantly improved (all P<0.05). Conclusions:Nusinersen can improve the motor function of patients with 5q spinal muscular atrophy, which is also proved safe to be used in children. The drug treatment supplemented by the multi-disciplinary team management is helpful to improve the multi-system function of the children with spinal muscular atrophy.
