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.

Objective: To investigate the association between plant-based dietary patterns and gestational weight gain (GWG) among pregnant women with gestational diabetes mellitus (GDM), so as to provide the evidence for guiding the reasonable diet during pregnancy. Methods: GDM pregnant women who participated in the WeBirth project in Hangzhou Obstetrics and Gynecology Hospital were selected. Maternal age and pre-pregnancy body mass index (BMI) were collected. The Chinese version of Pregnancy Physical Activity questionnaire was used to assess the daily activity equivalent. The food frequency questionnaire was used to collect the frequency and amount of food intake in the last month before enrollment. The overall plant-based diet index (PDI), healthy plant-based diet index (HPDI), and unhealthy plant-based diet index (UPDI) were constructed based on food intake and grouped by quartiles. Multiple linear regression models were used to analyze the association between plant-based dietary patterns and GWG. Results: A total of 1 943 pregnant women with GDM, with a median age of 30.91 (interquartile range, 4.92) years. The median BMI of pre-pregnancy was 21.51 (interquartile range, 4.06) kg/m2. The medians of PDI, HPDI and UPDI were 32.42 (interquartile range, 4.60), 32.48 (interquartile range, 4.41) and 32.40 (interquartile range, 5.36), respectively. The median of GWG was 11.30 (interquartile range, 4.52) kg. Multiple linear regression analysis showed that PDI (Q3 group, β=0.674, 95%CI: 0.064-1.285; Q4 group, β=0.702, 95%CI: 0.098-1.306), UPDI (Q3 group, β=1.332, 95%CI: 0.771-1.894; Q4 group, β=1.115, 95%CI: 0.550-1.681) were positively associated with GWG after adjusting for age, pre-pregnancy BMI, daily activity equivalent and daily energy intake. No significant association was found between HPDI and GWG (all P>0.05). Conclusion UPDI was associated with a higher risk of GWG in pregnant women with GDM.

Objective To investigate the characteristics of oral and laryngeal diadochokinesis abilities and the developmental patterns of coordinated vocal fold movements in preschool children aged 3～6 years.Methods Sixty-one normal preschool children aged 3～6 years were selected to measure their maximum phonation time(MPT),as well as two types of acoustic parameters of oral and laryngeal diadochokinesis ability movements,including the as-sessment of one trisyllabic/pataka/diadochokinesis ability rate and four monosyllabic/?a/,/ha/,/?A/,/hA/la-ryngeal diadochokinesis ability rates.Results Diadochokinesis ability(DDK)and laryngeal diadochokinesis ability(LDDK)rates increased with age in preschool children aged 3～6 years,showing highly significant differences(P＜0.01).The growth rate of children's LDDK rates at age 4～5 years was the maximum within the 3～6 year age range.Children's MPT was highly significantly and positively correlated with DDK and LDDK(P＜0.01).The vo-cal fold adduction capacity in laryngeal diadochokinesis ability movements in children of all age groups was greater than vocal fold adduction ability/?a/LDDK＞/ha/LDDK(P＜0.01),/?A/LDDK＞/h∧/LDDK(P＜0.05).Con-clusion Age,MPT,and vocal fold adduction and abduction status had a significant effect on the oral and laryngeal diadochokinesis ability of preschool children aged 3～6 years old.The ages of 4～5 is a critical period for the devel-opment of children's oral and laryngeal diadochokinesis ability.

Purpose To investigate the feasibility of apoptosis small-molecule probe CYS-F for in vivo molecular imaging in acute middle cerebral artery embolization and recalculation models,and to explore its ability to reflect lesions.Materials and Methods Hela cell apoptosis was induced by Adriamycin,and the targeting ability of the probe was verified in vitro.Clinical middle cerebral artery embolization was simulated,acute ischemic stroke model(n=15)and recanalization model(n=15)were constructed,and the vessels were evaluated by magnetic resonance angiography imaging.The distribution of CYS-F was investigated by injecting the probe into the caudal vein.24 hours after modeling,the lesion volume rate was assessed on T2WI,and apoptosis was assessed in vivo by near infrared imaging.Niss and c-fos staining were used to compare the differences between the two groups.Results CYS-F showed a good ability to target apoptosis in vitro.After modeling,Doppler flowmeter and magnetic resonance angiography showed that the middle cerebral artery was successfully embolized in the embolization group,and the artery was recanalized in the recanalization group.Near infrared imaging showed the loss of fluorescence signal in the middle cerebral artery region in the embolized group.24 hours after modeling,T2WI showed that the infarct volume rate in the recanalization group was significantly lower than that in the embolization group(0.055±0.015 vs.0.512±0.220;t=19.761,P<0.001).The fluorescence intensity of the embolization group was significantly stronger than that of the recusing group,the target to background ratio was 1.215±0.162 and 0.731±0.085,respectively(t=10.252,P<0.001).In the embolization group,a large number of activated neurons expressed c-fos protein,and a large number of cells underwent nuclear condensation and lysis by Niss staining.Conclusion The acute embolization model and recalculation model of middle cerebral artery in mice are close to the clinic.CYS-F can be used to image apoptosis in vivo,reflect the lesion degree,and reflect the local tissue blood perfusion at the initial stage of injection.

Objective:To investigate the efficacy and safety of AcoStream peripheral thrombus aspiration system combined with catheter-directed thrombolysis in the treatment of lower extremity deep vein thrombosis.Methods:The clinical data of 16 lower extremity deep vein thrombosis cases treated with AcoStream peripheral thrombus aspiration system combined with catheter-directed thrombolysis, admitted to the authors′ hospital from May 2022 to November 2022, were retrospectively analyzed. The differences in circumferential diameter between the affected limb and the healthy side, venous patency score, thrombus clearance grade and intraoperative blood loss were observed and compared. The Villalta score was used during the follow up. Paired sample t-test and Wilcoxon rank sum test were used to compare the changes in the observed indicators before and after treatment to evaluate the efficacy. Results:Treatment were successfully performed in all patients. Before treatment, the circumference differences between the affected and unaffected thighs and calves were (3.69±0.97) and (3.34±0.75)cm, respectively, the venous patency score of the affected side was 8(7.25,9) points. After treatment, the circumference differences between the affected and unaffected thighs and calves were (0.81±0.68) and (0.84±0.70)cm, respectively. The venous patency score of the affected side was 1(0,1)points, with statistically significant differences ( P<0.001). Grade Ⅲ thrombus clearance was achieved in 7 patients, grade Ⅱ thrombus clearance was achieved in 9 patients. The average blood loss during thrombus aspiration was (133.1±12.0) ml. Following up for 6 months, the Villalta score was 0(0,1.75) points. Conclusion:Acostream peripheral thrombus aspiration system combined with catheter-directed thrombolysis is safe and effective for the treatment of lower extremity deep venous thrombosis, with satisfactory short-term efficacy and high clinical application value.

BACKGROUND:It has been reported that the application of biotic amniotic membrane and corneal bandage lens in pterygium surgery can significantly reduce the pain reaction after pterygium excision and promote the healing of corneal wounds. OBJECTIVE:To compare the efficacy of biotic amniotic membrane and corneal bandage lens on the repair of corneal wounds and neuropathic pain after pterygium surgery. METHODS:A total of 121 cases(142 eyes)of primary pterygium patients admitted to Nanyang Second People's Hospital from August 2020 to May 2022 were retrospectively selected.They all underwent pterygium excision combined with autogenous free conjunctival flap transplantation.Among them,63 cases(68 eyes)of pterygium postoperative wound repair with biotic amniotic membrane were classified as the amniotic membrane group,and 58 cases(74 eyes)of pterygium wound repair with corneal bandage lens were classified as the bandage lens group.Postoperative follow-up was conducted,and the corneal wound repair of the patients within 2 weeks after surgery was recorded.Neuropathic pain was quantified by Wong-Baker face on the day after surgery,1 day,and 2 weeks after surgery.The corneal topographic map indicating asymmetry index,best corrected visual acuity,corneal refractive index,and surface rule index were recorded before surgery,1 and 3 months after surgery. RESULTS AND CONCLUSION:(1)2 weeks after treatment,the wound repair rate in the bandage lens group was significantly higher than that in the amniotic membrane group(P<0.05).The wound healing time was shorter in the bandage lens group than that in the amniotic membrane group(P<0.01).(2)The degree of neuropathic pain in the bandage lens group was lower than that in the amniotic membrane group on the day and 1 day after surgery(P<0.001),and there was no significant difference between the two groups in neuropathic pain at 2 weeks after surgery(P>0.05).(3)The corneal topographic map indicating asymmetry index,best corrected visual acuity,corneal refractive index,and surface rule index were significantly improved in both groups 1 and 3 months after surgery(P<0.05).The corneal topographic map indicating asymmetry index,corneal refractive index,and surface rule index of the bandage lens group were lower than those of the amniotic membrane group 1 and 3 months after surgery(P<0.05).(4)Recurrence occurred in 1 eye(1.47%)in the amniotic membrane group and 3 eyes(4.05%)in the bandage lens group within 3 months after operation,and there was no significant difference between the groups(P>0.05).(5)These findings suggest that the corneal bandage lens is more effective than the biotic amniotic membrane in the repair of corneal wounds after pterygium surgery.

Gorham-Stout disease(GSD)is a sporadic chronic disease characterized by progressive bone dissolution,absorption,and disappearance along with lymphatic vessel infiltration in bone-marrow cavities.Although the osteolytic mechanism of GSD has been widely studied,the cause of lymphatic hyperplasia in GSD is rarely investigated.In this study,by comparing the RNA expression profile of osteoclasts(OCs)with that of OC precursors(OCPs)by RNA sequencing,we identified a new factor,semaphorin 3A(Sema3A),which is an osteoprotective factor involved in the lymphatic expansion of GSD.Compared to OCPs,OCs enhanced the growth,migration,and tube formation of lymphatic endothelial cells(LECs),in which the expression of Sema3A is low compared to that in OCPs.In the presence of recombinant Sema3A,the growth,migration,and tube formation of LECs were inhibited,further confirming the inhibitory effect of Sema3A on LECs in vitro.Using an LEC-induced GSD mouse model,the effect of Sema3A was examined by injecting lentivirus-expressing Sema3A into the tibiae in vivo.We found that the overexpression of Sema3A in tibiae suppressed the expansion of LECs and alleviated bone loss,whereas the injection of lentivirus expressing Sema3A short hairpin RNA(shRNA)into the tibiae caused GSD-like phenotypes.Histological staining further demonstrated that OCs decreased and osteocalcin increased after Sema3A lentiviral treatment,compared with the control.Based on the above results,we propose that reduced Sema3A in OCs is one of the mechanisms contributing to the pathogeneses of GSD and that expressing Sema3A represents a new approach for the treatment of GSD.

Objective:To assess the prevalence of dentinal hypersensitivity (DH) and related factors in urban adults in China.Methods:The study was designed as an observational, cross-sectional epidemiological study carried out in adults aged 18-69 years old in seven cities (Beijing, Shanghai, Wuhan, Chengdu, Xi′an, Guangzhou, and Harbin) of China. The study was conducted from March 2021 to May 2023. Patients were required to complete a questionnaire regarding the subjects′ socio-economic factors, dietary behavior, oral health behavior and personal antecedent factors. DH was clinically diagnosed by judging whether the tooth cold air stimulation provoked DH or not, and recorded by investigator pain rating Schiff score. Compare the findings of six cities (Harbin excluded) with a similar study conducted in 2008.Results:In total, 11 622 subjects from seven cities in China participated the study. Fifty two point two percent (6 072/11 622) of subjects reported DH in questionnaire, 36.7% (4 266/11 622) of subjects reported experiencing DH in response to cold air stimulation for at least one study tooth. Risk factors including age, sex, city, toothbrush method and acid reflux showed marked associations with DH ( P<0.05). The prevalence of DH of urban residents in six cities (Harbin excluded) was 33.7% (3 335/9 882), higher than that in 2008 [29.7%(2 354/7 939)]. Conclusions:Overall, DH was common among urban adults in China and the prevalence increased in recent years. Better understanding of DH and its associated factors should be considered in its prevention and management by dental professionals.

Objective To explore the related factors of lymph node metastasis in early gastric cancer and to analyze the clinical efficacy between laparoscopic D2 radical resection and endoscopic submucosal dissection(ESD).Methods A retrospective cohort study was conducted on 404 patients with early gastric cancer undergoing surgical treatment in our hospital from June 2018 to June 2022 were recruited in this study.According to their surgical treatment,they were divided into laparoscopy group(n=271)and ESD group(n=133).The lymph node metastases were compared in the patients with different clinical features,and the factors affecting lymph node metastasis were analyzed with multivariate logistic regression analysis.The lymph node metastasis rate of patients with absolute and expanded indications of ESD was calculated.Kaplan-Meier survival analysis was used to compare the long-term efficacy of ESD and laparoscopic D2 radical resection in these patients.Stratified regression analysis was applied to explore the relationship between surgical methods and long-term outcome in them.Results In the 404 patients with early gastric cancer,the rate of lymph node metastasis was 12.38％(50/404).Univariate analysis showed that 7 clinical features,such as ulcer,tumor pathological features and pathological differentiation,were related to lymph node metastasis.Multivariate logistic regression analysis revealed that low differentiation and tumor infiltration depth of submucous membrane(SM)were related factors affecting lymph node metastasis in early gastric cancer.The overall survival rate was 96.29％(389/404)in the 404 patients,96.31％in the laparoscopic group and 96.24％in the ESD group,and no statistical difference was seen between the 2 groups(P＞0.05).There was no obvious difference in 5-year survival rate between the patients who met the absolute indications for ESD and underwent laparoscopic D2 radical surgery and those receiving ESD treatment(96.00％vs 96.55％),and between those who were in accordance with the expanded indications for ESD and underwent laparoscopic D2 radical surgery and those receiving ESD treatment(94.74％vs 91.67％).After adjusting the clinical features such as lesion size,pathological differentiation and depth of tumor invasion by stratified regression analysis,the mode of operation for early gastric cancer was still correlated with the long-term efficacy(β=1.173,P=0.003).Conclusion The depth of tumor infiltration and differentiation are closely related to lymph node metastasis in early gastric cancer patients.The efficacy of laparoscopic D2 radical surgery on the patients with absolute and expanded indications for ESD is comparable to that of ESD treatment.
