Objective The aim of this study was to retrospectively review the efficacy and safety of treatment for unresectable locally advanced non-small cell lung cancer (LA-NSCLC).Methods A total of 98 patients treated in our hospital between January 2010 and December 2015 were enrolled in this study.Patients were divided into three groups:the thoracic radiotherapy (TRT) alone,concurrent chemoradiotherapy,and sequential chemoradiotherapy groups.The progression-free survival (PFS) and overall survival (OS) were analyzed via the Kaplan-Meier method,and compared with the log-rank/Breslow test.The prognostic factors were analyzed using the Kaplan-Meier and Cox multivariate proportional hazards models.Results The median PFS in the concurrent therapy group was longer than that in the TRT alone group (P ＜ 0.05).The median OS was improved in patients treated with concurrent or sequential therapy than in the TRT alone group (P ＜ 0.05).N stage,chemotherapy regimens,and radiotherapy modalities were independent prognostic factors of PFS in all patients (P ＜0.05).Similarly,N stage was an independent prognostic factor of OS in all patients (P ＜ 0.05).Overall,the treatment was deemed safe.The occurrence of hematotoxicity related to Karnofsky performance score (KPS) and chemotherapy regimens (P ＜ 0.05).Conclusion Patients with a lower N stage who received cisplatin-based double chemoradiotherapy demonstrated improved survival rates.Survival was significantly improved in LA-NSCLC patients treated with concurrent or sequential therapies compared with TRT alone.Overall,the treatment is safe.KPS and chemotherapy combination regimens may increase the occurrence of hematotoxicity.

Clinical phenotype and gene characteristics of a patient diagnosed with Imerslund-Gr?sbeck syndrome (IGS) in Department of Neurology, Children′s Hospital of Soochow University in December 2018 were analyzed retrospectively, and literature review was conducted.The 16 years and 5 months old boy was admitted to the hospital with symptoms of weakness of lower limbs for 2 weeks.He had a history of megaloblastic anemia and isolated proteinuria.Genetic metabolism of hematuria showed methylmalonic academia.Genetic analysis revealed a compound heterozygous AMN gene mutation[c.742C>T(p.Q248 *) and c. 761G>A(p.G254E)]. These two mutations were derived from his parents respectively, which had been reported before.Symptoms of the patient improved after intramuscular administration of hydroxycobalamin and oral betaine.Review of the literature indicated that the clinical manifestations of AMN gene-related IGS were mostly megaloblastic anemia and isolated proteinuria, and the older children might suffer from neurological symptoms such as movement disorders, dementia, delirium or psychosis.The clinical phenotype of this disease was variable, which might easily lead to misdiagnosis.The patient presented with a special phenotype of mild reversible peripheral neuropathy, which expanded the clinical phenotype of pathogenic genes of AMN gene.In addition, peripheral neuropathy caused by vitamin B 12 metabolic disorders is reversible, and it is suggested to measure vitamin B 12, test related genes and treatment with vitamin B 12 in peripheral neuropathy of unknown etiology.

Objective To systematically review the effect of high blood flow restriction training(BFRT)on patients after anterior cruciate ligament reconstruction(ACLR). Methods Relevant literature was searched in PubMed,Web of Science,Embase,Cochrane Library,CNKI,CBM,Wan-fang data,and VIP databases using subject term search methods from the inception to May 1st,2024.The meth-odological quality of the included literatures was assessed using Physiotherapy Evidence Database(PEDro)scale,and relevant data were extracted for systematic review. Results A total of seven articles were finally included,involving 183 subjects from six countries.The intervention sites were mainly hospital rehabilitation departments and rehabilitation centers.The publication dates ranged from 2016 to 2023.In BFRT group,lower limbs were compressed during conventional rehabilitation training,with in-termittent of 0.5 to 2 minutes or without deflation.BFRT would increase muscle strength,muscle hypertrophy,and improved knee joint function.Total duration of intervention and training intensity affected the improvement. Conclusion High BFRT can improve the condition of the muscles around the knee joint and promote functional recovery after ACLR.To ensure the safety and effectiveness of the training,low-intensity strength training should be em-ployed,with 15 to 30 repetitions per set,four to five sets per session,two to three sessions per week,and a total training duration of at least three weeks.

Objective To review the effect of orthopedic insoles on arch morphology,pain and lower limb motor function in chil-dren and adolescents with flexible flatfoot. Methods Relevant literature was retrieved from PubMed,Web of Science,Embase,CNKI,CBM,Wanfang data and VIP databases,from inception to October,2024,and a scoping review was conducted. Results Ten researches were included,comprising seven cohort studies and three randomized controlled trials,originat-ing from China,Korea,Iran and Romania,involving 520 children and adolescents with flexible flatfoot.Orthope-dic insoles could increase the calcaneal pitch angle,reduce the Meary's angle and arch index;improve motor function of feet and lower limbs,stability of anterior and posterior,medial,and overall,adjust the kinematics and ground reaction force in walking;relieve pain and reduce incidence of pain. Conclusion Wearing orthopedic insoles could improve the arch morphology,dynamic balance and gait function,and re-lieve pain in children and adolescents with flexible flatfeet.

AIM:To investigate the effects of the compound ANBP on wound healing in diabetic rats and ex-plore its mechanism of action.METHODS:Ninety male SD rats were randomly divided into blank,model,compound ANBP,Beifuxin,and nicotinamide mononucleotide(NMN)groups,with 16 rats in each group.Wound healing in each group was observed and samples were taken on days 3,7 and 14 to analyze the wound healing rate.Local histopathological changes were observed using HE and Masson staining.The expressions of pyruvate dehydrogenase E1 subunit alpha 1(PDHA1),citrate synthase(CS),isocitrate dehydrogenase(IDH1)and oxoglutarate dehydrogenase(OGDH)were de-tected through immunofluorescence and Western blot.The number and morphology of mitochondria in the wound tissue were observed using transmission electron microscopy.RESULTS:Histomorphological changes revealed significant im-provement in diabetic wound healing in the blank and compound ANBP groups compared to that of the model group.The wound healing rates of the blank,compound ANBP,Beifuxin,and NMN groups were significantly increased on days 3,7,and 14(P<0.01).Compared to the model group,granulation tissue generation was higher in the other groups,cover-ing the wound defect and producing abundant collagen fibers.At 3,7,and 14 days after intervention,the blank,com-pound ANBP,Beifuxin,and NMN groups showed significantly enhanced fluorescence intensities of TCA cycling-related enzymes PDHA1,CS,IDH1,and OGDH indicating increased expression of these enzymes.The levels of the TCA cy-cling-related enzymes were significantly increased(P<0.01)in the compound ANBP,Beifuxin and NMN groups but were significantly decreased(P<0.01)in the model group.An increase in the number and density of mitochondria and a de-crease in the cavitation rate of mitochondria with improved morphology(P<0.05)was observed in the group treated with compound ANBP.CONCLUSION:Compound ANBP may increase the number of mitochondria,improve mitochondrial morphology and function,upregulate the expression levels of PDHA1,CS,IDH1,and OGDH proteins,and accelerate the regeneration of wound granulation tissue,thus promoting the healing of diabetic wounds in rats.

Objective     To analyze the clinical efficacy and safety of endostar or carboplatin combined with endostar intracavitary perfusion in the treatment of malignant serous cavity effusion. Methods     We retrospectively reviewed the clinical data of 78 cancer patients with malignant serous cavity effusion who received paracentesis and intracavitary endostar, or carboplatin combined with endostar in Shengjing Hospital of China Medical University between November 2011 and November 2016. There were 42 males and 36 females at a median age of 62 years ranging from 17 to 78 years. According to treatment methods, 78 patients were divided into two groups, in which 33 patients received intracavitary endostar combined with carboplatin (a combination group, 15 males and 18 females at a median age of 56 years ranging from 17 to 66 years), and 45 patients received intracavitary endostar (an endostar group, 27 males and 18 females at a median age of 63 years ranging from 38 to 78 years). The efficacy and safety of two methods were analyzed and compared. Results     The response rate in the combination group was 75.8%, which was higher than that in the endostar group (60.0%, P=0.035). In quality of life improvement, there was no statistical difference between the two groups (P=0.113). The incidence of fatigue, myelosuppression and gastrointestinal reactions in the endostar group was significantly lower than that of the combination group (P=0.006, 0.000 and 0.017, respectively). Analysis of long-term efficacy revealed that the median time to progress (TTP) in the combination group and endostar group was 171 days and 143 days, respectively (P=0.030). Conclusion     Intracavitary infusion of endostar alone, or carboplatin combined with  endostar is effective and tolerable for controlling malignant serous cavity effusion. But for the patients with poor physical state who can not tolerant platinum perfusion, intracavitary infusion of endostar alone can be adopted to control malignant serous cavity effusion.
