Objective:To analyze the clinical features and genetic sequencing results of a patient with Kallmann syndrome(KS) carrying digenic mutations who initially presented with osteoporosis, and to enhance awareness of this disease phenotype.Methods:Clinical data were collected, and peripheral blood DNA was extracted for whole-exome sequencing. Relevant literature was reviewed to summarize phenotypes associated with digenic/oligogenic variants involving CHD7.Results:The patient exhibited back pain, delayed development of secondary sexual characteristics, and hyposmia. Laboratory tests revealed reduced sex hormones and gonadotropin levels, while pituitary imaging was unremarkable. Bone mineral density imaging confirmed osteoporosis, and thoracolumbar X-rays showed multiple vertebral compression fractures. Genetic analysis identified a heterozygous splice-site mutation in CHD7(c.2698-1G>T) and a heterozygous missense mutation in WDR11(c.439G>A: p.D147N). According to ACMG criteria, the CHD7 mutation was classified as pathogenic, while the WDR11 variant was defined as a variant of uncertain significance(VUS). Literature review indicated that 40% of KS patients with digenic/oligogenic variants involving CHD7 presented with hearing or ocular abnormalities.Conclusion:This study reports a novel CHD7 mutation and a previously undescribed digenic combination of CHD7 and WDR11 variants in a KS patient. CHD7 variants may be implicated in auditory or ocular involvement in KS cases with digenic/oligogenic inheritances. KS patients may also manifest skeletal abnormalities in addition to hypogonadotropic hypogonadism. Tailored management of sex hormones and osteoporosis therapies across life stages is essential for optimizing bone health in KS.

BackgroundFloortime therapy（FTT） as a child-centered intervention approach， has gained increasing attention in the rehabilitation training of children with Autism Spectrum Disorder （ASD）. In recent years， it has shown unique advantages and potentials in the education and treatment of autistic children.Currently， domestic research on the application of FTT in ASD treatment remains limited. ObjectiveTo explore the intervention effects of FTT on children with ASD， so as to provide references for rehabilitation treatment. MethodsA total of 30 children diagnosed with ASD according to the Diagnostic and Statistical Manual of Mental Disorders， Fifth Edition （DSM-5） criteria，and receiving rehabilitation training at the Child Mental Health Department in the Third Hospital of Mianyang were enrolled from January 2022 to December 2023. All participants received FTT for 9 months. Assessments were conducted using the Childhood Autism Rating Scale （CARS） and the Functional Emotional Assessment Scale （FEAS） at baseline， and the 3^rd， 6^th， and 9^th month of intervention. ResultsThe time effects on CARS score and total FEAS score in children with ASD were both statistically significant （F=43.184， 80.232， P<0.01 ）. At the 3^rd， 6^th and 9^th months of treatment， the CARS scores of ASD children were significantly lower than baseline （t=5.232， 11.997， 16.600， P<0.01 ）， while the total FEAS scores were significantly higher than baseline（t=-4.048， -10.566， -14.615， P<0.01 ）. ConclusionFTT may help to improve the functional emotional capacities and alleviate ASD symptoms in children.［Funded by The 2022 Incentive Research Project of Health Commission of Mianyang City （number，202245）］

Objective To investigate the relationship between 418 C>G polymorphism of tissue metalloproteinase inhibitor-2(TIMP-2)gene and susceptibility to non-small cell lung cancer(NSCLC).Methods A total of 167 patients with NSCLC admitted to Suining Central Hospital from May 2021 to May 2023 were selected as the observation group,and 183 healthy subjects who underwent physical examination in the hospital during the same period were selected as the control group.The general data of the two groups were compared and the polymorphism of the TIMP-2 gene was analyzed.The genotype and allele frequency distribution of the polymorphic locus of the TIMP-2 gene were detected and compared between the two groups.Logistic regression was used to analyze the correlation between TIMP-2 gene 418 C>G site and NSCLC.Results The proportion of BMI≥24kg/m2 and smoking in the observation group were 67.07%and 61.08%,respectively,which were 44.26%and 40.44%in the control group,and the differences were statistically significant(χ2=18.356,14.881,all P<0.001).The variant GG homozygote produced three fragments of 230bp,51bp and 23bp in length,the wild-type CC homozygote produced 253bp and 51bp in length,and the heterozygous GC produced four pieces of 253bp,230bp,51bp and 23bp in length.The 51bp and 23bp fragments were not shown,and the TIMP-2 418 C>G gene identity was 100%.The genotype frequencies met the Hardy-Weinberg genetic equilibrium(P>0.05).The frequencies of CC,GC and GG of the TIMP-2 genotype in the observation group were 10.18%,41.92%and 47.90%,respectively,and those in the control group were 4.37%,37.70%and 57.92%,respectively,and the difference was statistically significant(χ2=6.163,P=0.046).The frequencies of the C and G alleles of TIMP-2 in the observation group were 31.14%and 68.86%,respectively,and those in the control group were 23.22%and 76.78%,respectively,and the difference was statistically significant(χ2=5.549,P=0.018).Compared with the control group Logistic regression analysis showed that genotype carrying the C allele significantly increased the risk of NSCLC(OR=2.669,95%CI:1.478～2.936,P<0.01).Compared with the GG+GC group,the proportion of patients with CC genotype who had poor chromosome karyotype prognosis,the proportion of high-risk group in the International Prognostic Scoring System(IPSS)risk group and the levels of CRP and PCT were increased,and the differences were statistically significant(t=3.633～11.249,all P<0.001).Absolute neutrophil count(ANC),Haemoglobin(HGB)and Platelet(PLT)decreased,and the differences were statistically significant(t=4.760,2.015,2.212,all P<0.05).Multivariate COX regression analysis showed that CC genotype,chromosome karyotype,IPSS risk group,ANC,HGB,PLT,CRP,and PCT were risk factors for poor prognosis in NSCLC(Wald χ2=3.072～17.611,all P<0.05).The results of the multifactor dimensionality reduction(MDR)method showed that the interaction combination of abnormal ANC,HGB,PLT,CRP,and PCT levels and TIMP-2 gene polymorphism was 2.650 times higher than that of NSCLC.Conclusion The CC genotype and C allele of the 418 C>G locus of TIMP-2 gene are significantly associated with the risk of NSCLC and are independent risk factors for NSCLC.

Objective To investigate the clinical efficacy of fire dragon pot comprehensive therapy in patients with knee paralysis due to liver and kidney deficiency following total knee arthroplasty(TKA).Methods A total of 114 patients undergoing unilateral TKA were randomly assigned to two groups using a random number table.The control group(n=57)received standard enhanced recovery after surgery(ERAS)nursing care,while the intervention group(n=57)received high-frequency general massage(HGM)therapy in addition to the standard ERAS protocol.Outcomes including visual analogue scale(VAS)scores,Hamilton Anxiety Scale(HAMA)scores,Hospital for Special Surgery(HSS)knee scores,and serum levels of inflammatory markers[C-reactive protein(CRP),neutrophil count(NE),and lymphocyte count(LY)]were compared between the two groups.Results Compared with the control group,the intervention group exhibited significantly lower VAS scores at 3 days postoperatively and at discharge,reduced HAMA scores from the preoperative period through 3 days after surgery,improved HSS scores[specifically in pain,function,range of motion,stability,and total score]at 2 weeks postoperatively,and more pronounced improvements in inflammatory markers,including lower levels of CRP and NE and higher LY levels(all P<0.05).Conclusion The comprehensive moxibustion therapy using Huolongjar effectively alleviates postoperative pain following TKA,enhances joint function,reduces anxiety levels,and mitigates inflammatory responses.This intervention is safe,simple to administer,and holds promise for clinical application and wider dissemination.

Objective:To explore the effectiveness of predictive exercise intervention combined with information-knowledge-attitude-practice (IKAP) model-based nursing in patients with gestational hypertension (GH) .Methods:Convenience sampling was used to select 130 GH patients admitted to Taizhou Hospital of Zhejiang Province from January 2022 to December 2024 for the study. Sixty-five GH patients admitted from January 2022 to June 2023 were set as control group, and 65 GH patients admitted from July 2023 to December 2024 were set as observation group. Control group implemented conventional nursing, and observation group was treated with predictive exercise intervention combined with IKAP model-based nursing on the basis of conventional nursing. Depression, delivery outcomes, and incidence of complications were compared between two groups of GH patients after intervention.Results:During the study period, no patients were excluded from observation group and one patient was withdrawn from control group for personal reasons, resulting in the inclusion of 64 patients. Patients in observation group at 6 weeks postpartum had lower scores on the Chinese version of the Edinburgh Postnatal Depression Scale than those in control group, and the incidence of premature labor, cesarean section, and lower limb swelling were lower than those in control group, and the differences were all statistically significant ( P<0.05) . Conclusions:Predictive exercise intervention combined with IKAP model-based nursing can improve the coagulation function of GH patients, reduce the incidence of lower limb swelling, alleviate the patient's postpartum depression, and facilitate safe delivery.

Objective To investigate the impact of scenario class teaching on language expression,communication skills,and final exam performance of non-clinical majors students in the course of Medical Parasitology.Method Undergraduate students of non-clinical medical programs from Kunming Medical University in 2022 were selected as the subjects and randomly divided into a scenario class group and a non-scenario class group.Questionnaires were administered to compare the two groups regarding their interest in the laboratory classes,enjoyment levels,and knowledge retention.Additionally,the final exam scores of the two groups were compared.Results Students in the scenario class group showed significantly higher interest(82.6%)and enjoyment levels(88.3%)for laboratory classes compared to the non-scenario class group(73.0%and 60.1%,respectively,P<0.05).Students in the scenario class group believed that situational teaching enhanced their self-learning ability(82.06%),interest in learning(83.2%),willingness to express themselves(83.2%),confidence in expression(81.8%),and communication skills(87.9%).Additionally,It effectively facilitated their understanding of the occurrence and development of parasitic diseases(85.9%)and familiarity with the diagnosis and treatment process(86.8%),thereby cultivating clinical thinking.In terms of final exam scores,the scenario class group had a higher average score(22.80±0.18)than the non-situational classroom group(21.47±0.17,P<0.05).Conclusion Sc-enario class teaching in Medical Parasitology can effectively improve students'self-learning ability,language expression,and communication skills,cultivate clinical thinking,and enhance academic performance,demonstrating significant teaching advantages.

Objective To compare the effects of main artery clamping(MAC)and selective artery clamping(SAC)strategies on postoperative renal function in patients with chronic renal insufficiency undergoing robot-assisted partial nephrectomy.Methods A retrospective cohort study was conducted on 231 patients with preoperative chronic renal insufficiency[eGFR<90 mL/(min·1.73 m2)with renal injury markers or eGFR<60 mL/(min·1.73 m2)]who underwent robot-assisted partial nephrectomy in the Department of Urology of the First Affiliated Hospital of Army Medical University from February 2018 to February 2024.According to intraoperative renal artery clamping strategy,they were divided into a MAC group(n=129)and a SAC group(n=102).Preoperatively,individualized renal artery clamping strategies were developed using a machine learning-based multimodal holographic 3-D reconstruction technique.Serum creatinine(Scr)level was measured at 3 d and 3 months after surgery,and estimated glomerular filtration rate(eGFR)was calculated using the chronic kidney disease epidemiology collaboration equation(CKD-EPI)formula.Renal dynamic imaging with 99mTc-DTPA or 99mTc-MAG3 was used to assess the GFR of the affected kidney.Results At 3 d after surgery,the decrease in GFR of the affected kidney was significantly lower[(8.3±7.7)vs(16.0±10.2)mL/(min·1.73 m2),95%CI:-10.2～-5.2,P<0.001]in the SAC group than the MAC group.Scr increment analysis showed that the SAC group exhibited notably lower Scr increase[8.2(2.5,18.7)vs 15.5(5.8,28.3)μmol/L,95%CI:-12.3～-1.8,P=0.027],and milder eGFR decline[3.0(0.5,7.8)vs 7.5(2.0,14.3)mL/(min·1.73 m2),95%CI:-6.2～-0.8,P=0.015].And,in 3 months after surgery,the SAC group had lower Scr level[(89.2±23.1)vs(95.3±22.1)μmol/L,95%CI:-11.9～-0.3,P=0.042],and higher GFR of the affected kidney[(33.5±10.5)vs(26.1±10.9)mL/(min·1.73 m2),95%CI:4.6～10.2,P<0.001].Conclusion For patients with chronic renal insufficiency undergoing robot-assisted partial nephrectomy,SAC strategy is superior to MAC strategy in protecting postoperative renal function without increasing surgical risk.
