Objective:To analyze the distribution of tumor necrosis factor-alpha（TNF-α）308 gene loci polymorphism in children with febrile seizures（FS）and to explore the correlation between TNF-α 308 gene polymorphisms and FS in children.Methods:A total of 320 children diagnosed with FS in the Department of Emergency，Shanghai Children's Hospital from September 1st，2020 to June 30th，2021 were enrolled as the study subjects，which were divided into simple febrile seizures（SFS）group（232 cases）and complex febrile seizures（CFS）group（88 cases）based on their clinical characteristics，and the clinical characteristics and laboratory indexes of the two groups were compared. Children with no history of convulsions were selected as the control group（160 cases）. The high-resolution melting and gene sequencing technology were used to analyze the polymorphism of TNF-α 308 gene in each group and the distribution of different gene types and allele frequencies among the groups was compared. A multivariate Logistic regression model was constructed to analyze the relationship between TNF-α 308 gene polymorphism and FS.Results:The age，mean corpuscular volume，mean corpuscular hemoglobin and platelet distribution width of the CFS group were significantly higher than those in the SFS group，and the difference was statistically significant（all P<0.05）.There was no significant difference in gender distribution，family history of FS，history of FS，body temperature at time of convulsions，WBC，Hb，CRP and PLT between the two groups（all P>0.05）.The genotype frequency distribution of TNF-α 308 polymorphism in the three groups was in line with the Hardy-Weinberg equilibrium（ P>0.05）.The AA genotype of TNF-α 308 locus was not detected in the study.Compared with the control group［17 cases（10.6%）］，the distribution proportion of GA genotype in the CFS group［22cases（25.0%）］and the SFS group［52cases（22.4%）］was increased，and the difference was statistically significant（ χ2＝11.126， P＝0.004）；Compared with the control group［17 frequencies（5.3%）］，the frequency distribution proportion of allele A in the CFS group［22 frequencies（12.5%）］and SFS group［52 frequencies（11.2%）］was also increased，and the difference was statistically significant（ χ2＝9.960， P＝0.007）. Adding control factors such as gender，age，family history of FS，body temperature at time of convulsions and blood routine markers，the multivariate Logistic regression model was constructed to show that there was no statistically significant association between TNF-α 308 genotype and CFS in children（ OR＝1.805，95% CI：0.926~3.519， P＝0.083）. Conclusion:In this study，there was no significant correlation between TNF-α 308 gene loci polymorphism and CFS in children.

Objective To investigate the correlation between serum insulin like growth factor 1 receptor(IGF1R)and epidermal growth factor-like domain-containing protein 7(EGFL7)levels and the condition and pregnancy outcome of patients with preeclampsia(PE).Methods A total of 120 PE patients admitted to the hospital from January 2021 to January 2024(PE group)and 60 healthy pregnant women during the same peri-od(control group)were selected.The PE patients were divided into severe PE group(68 cases)and mild PE group(52 cases)according to their conditions,and divided into poor group(62 cases)and good group(68 ca-ses)according to the pregnancy outcome.Enzyme-linked immunosorbent assay was used to detect serum IGF1R,EGFL7 levels.Using the pregnancy outcome of PE patients as the dependent variable,multivariate un-conditional Logistic regression was used to determine the influencing factors of their pregnancy outcomes,and receiver operating characteristic curve was used to evaluate the predictive value of serum IGF1R and EGFL7 levels.Results Compared with the control group,serum IGF1R levels were reduced and EGFL7 levels were increased in the PE group(t=-16.908,16.234,P＜0.001).Serum IGF1R levels were decreased and EGFL7 levels were increased in the severe PE group compared with the mild PE group(t=-5.317,5.305,P＜0.001).The incidence of adverse pregnancy outcomes in PE patients was 51.67％(62/120).The independent risk factors for adverse pregnancy outcomes in patients with PE were severe PE(OR=3.906,95％CI:1.305-11.689),elevated 24-h urinary protein(OR=2.030,95％CI:1.290-3.194),elevated EGFL7(OR=1.116,95％CI:1.040-1.198),and the independent protective factor was elevated IGF1R(OR=0.908,95％CI:0.865-0.954,P＜0.05).The area under the curve for serum IGF1R and EGFL7 levels alone and in com-bination to predict adverse pregnancy outcomes in PE patients was 0.791(95％CI:0.707-0.860),0.784(95％CI:0.700-0.854),and 0.866(95％CI:0.781-0.911),and serum IGF1R and EGFL7 levels were grea-ter jointly(Z=2.456,2.244,P＜0.05).Conclusion Decreased serum IGF1R levels and increased EGFL7 levels are associated with exacerbation and adverse pregnancy outcomes in patients with PE,and the combina-tion of serum IGF1R and EGFL7 levels is of high value in predicting adverse pregnancy outcomes in patients with PE.

BACKGROUND:Internal heat-type acupuncture therapy is a new treatment technique that combines acupuncture therapy with hyperthermia.It has good clinical effects on steroid-induced osteonecrosis of the femoral head,but the mechanism of action is still not fully clear. OBJECTIVE:To explore the possible mechanism of internal heat-type acupuncture therapy in treating steroid-induced osteonecrosis of the femoral head in rabbits. METHODS:Thirty-two New Zealand rabbits were randomly divided into blank group,model group,internal heat-type acupuncture group and shock wave group using a random number table method,with 8 rabbits in each group.The model group,internal heat-type acupuncture group and shock wave group were modeled using methylprednisolone sodium succinate combined with Escherichia coli endotoxin.The internal heat-type acupuncture group received an internal heat-type acupuncture intervention on the buttocks of rabbits,once a week,for 20 minutes each time.The shock wave group received shock wave intervention on the buttocks of rabbits,once a week,with 2 000 beats per session.The blank group and model group were not given any treatment.After 4 weeks of intervention,blood samples and bilateral femoral head samples were collected from experimental rabbits.The levels of tumor necrosis factor-α and interleukin-6 in serum were detected by ELISA;the histomorphology of the femoral head was observed using hematoxylin-eosin staining and the rate of empty lacunae was calculated;the protein expressions of matrix metalloproteinase 2,matrix metalloproteinase 9,matrix metalloproteinase tissue inhibitor 1,and matrix metalloproteinase tissue inhibitor 2 were detected by immunohistochemistry and western blot. RESULTS AND CONCLUSION:Compared with the blank group,the model rabbits showed reduced food intake,mental fatigue,and decreased activity;compared with the model group,the above performance of the experimental rabbits was significantly improved after internal heat-type acupuncture and shock wave treatment.Compared with the blank group,the histomorphology of the femoral head in the model group deteriorated significantly and the rate of empty bone lacuna increased(P<0.001),while the histomorphology of the femoral head in the internal heat-type acupuncture group and shock wave group was significantly improved compared with the model group,and the rate of empty bone lacuna was reduced(P<0.001).The serum levels of tumor necrosis factor-α and interleukin-6 in the model group were significantly higher than those in the blank group(P<0.05),while the serum levels of tumor necrosis factor-α and interleukin-6 in the internal heat-type acupuncture group and the shock wave group were significantly lower than those in the model group(P<0.05).Compared with the blank group,the expression levels of matrix metalloproteinase 2 and matrix metalloproteinase 9 in the femoral head of the model group were significantly increased,while the expression levels of matrix metalloproteinase tissue inhibitor 1 and matrix metalloproteinase tissue inhibitor 2 were significantly decreased(P<0.001);compared with the model group,the protein expression levels of matrix metalloproteinase 2 and matrix metalloproteinase 9 were significantly decreased,while the protein expression levels of matrix metalloproteinase tissue inhibitor 1 and matrix metalloproteinase tissue inhibitor 2 were significantly increased in the internal heat-type acupuncture group and the shock wave group(P<0.001).Overall,these findings indicate that internal heat-type acupuncture may promote the repair of the necrotic femoral head by regulating the levels of matrix metalloproteinases/matrix metalloproteinase tissue inhibitors and serum inflammatory factors,thus treating early steroid-induced osteonecrosis of the femoral head.

Objective To compare the efficacies of unilateral biportal endoscopic(UBE)technique and percutaneous transforaminal endoscopic discectomy(PTED)in the treatment of lumbar spinal stenosis.Methods Forty patients who were diagnosed with lumbar spinal stenosis in Chashan Hospital of Dongguan from January 2019 to January 2023 were enrolled in this retrospective study.They were divided into PTED group(n=20)and UBE group(n=20).Perioperative data(operation time,intraoperative bleeding,postoperative hospital stay,degree of decompression and complications)were compared between the two groups.Visual analogue scale(VAS)score and Oswestry dysfunction index(ODI)were collected before surgery and on 3 days,1 month and 6 months after surgery.Results There were no significant differences in the operation time,intraoperative bleeding,or hospitalization time between the two groups(all P>0.05).The incidence of postoperative complications in the UBE group was significantly lower than that in the PTED group(P=0.001).VAS score and ODI of the low back and leg pains in the UBE group were superior to the PTED group at each postoperative time point(all P<0.05).One month after surgery,the UBE group had a more significant increase in the dural sac cross-sectional area and intervertebral foramen area than the PTED group(t=3.842,P=0.003;t=2.469,P=0.006).Conclusion Compared with PTED,UBE has better clinical outcomes,higher degree of decompression,and lower incidence of complications.UBE is a safe and feasible surgical method for the treatment of lumbar spinal stenosis.

Objective To observe the effect of Bushen Gutai mixture on uterine blood supply of rat model of abortion induced by hydroxyurea tablets combined with mifepristone through PKA-CREB signal pathway and its mechanism of calming fetus.Methods 60 pregnant rats of SPF grade SD rats were prepared by closing cages at 2∶1.According to the order of pregnancy,60 pregnant rats were randomly divided into 6 groups with 10 rats in each group:Bushen Gutai mixture group(low,middle and high dose),normal pregnancy group,model group and Di qu progesterone group.On the 1st to 9th day of pregnancy,except the normal group,the pregnant rats in each group were gavaged with hydroxyurea tablets at 5∶00 pm every day(450 mg·kg-1),and at 10∶00 am on the 10th day of pregnancy.Mifepristone tablets were given by intragastric administration(4.0 mg·kg-1).At 9∶00 am every day from the 1st to 9th day of pregnancy,Bushen Gutai mixture was given to the low,middle and high dose groups(0.5,1.0,2.0 g·kg-1),didrone group(3.02 mg·kg-1),model group and normal pregnancy group with 0.9%normal saline.24 hours after the last administration of pentobarbital sodium(50 mg kg-1),all pregnant rats were killed by intraperitoneal injection of pentobarbital sodium,and the uterine decidual tissue of pregnant rats was bluntly isolated in sterile environment.Hematoxylin-eosin(HE)staining was used to observe the lumen diameter and wall thickness of spiral artery in uterine decidual tissue.Immunohistochemical staining(IHC)was used to detect the expression of vascular endothelial growth factor(VEGF)in decidual tissues.Western blot was used to detect the protein expression of phosphorylated protein kinase A,protein kinase A,phosphorylated cyclic adenosine monophosphate response element binding protein,Cyclic Adenosine monophosphate response element binding protein and aquaporin 5 in the decidua of pregnant rats.The apoptosis of decidual cells was detected by in situ end labeling(TUNEL)of DNA fragmentation.Results Compared with the model group,the wall thickness of spiral artery was higher than that in other groups(P<0.05),the lumen diameter was lower than that in other groups(P<0.05)and the expression of VEGF protein was lower than that of other groups(P<0.01).Compared with the model group,the apoptosis level of decidual cells in uterine decidua of abortive rats in high,middle and low dose groups of Bushen Gutai mixture and diqu progesterone group decreased in varying degrees.Bushen Gutai mixture can up-regulate the levels of p-PKA/PKA and p-CREB/CREB in uterine decidua(P<0.01)and promote the expression of AQP5 protein in uterine decidua of abortion rats(P<0.01).Conclusion Bushen Gutai mixture can improve uterine blood supply of aborted rats by activating PKA and CREB phosphorylation,up-regulating AQP5 expression,promoting physiological recasting of spiral artery and high expression of Vascular endothelial growth factor.

Objective:To evaluate the efficacy of Janus kinase (JAK) inhibitors in the treatment of 5 children with severe alopecia areata, especially those with complicated nail damage.Methods:A total of 5 children with severe alopecia areata were enrolled and treated with oral JAK inhibitors (tofacitinib or baricitinib). The improvement of hair loss was assessed by using the severity of alopecia tool (SALT) at 12, 24, 36, and 48 weeks after the start of treatment. For 3 children with complicated nail damage, the improvement of diseased nails and toenails was evaluated by using the modified nail psoriasis severity index after treatment. During the treatment, adverse reactions were monitored.Results:The 5 children with severe alopecia areata were aged 2 - 11 years, with the disease duration ranging from 5 to 120 months, and the treatment with JAK inhibitors lasted 24 - 48 weeks. After 12-week treatment, 2 children achieved a 50% improvement in SALT (SALT50) ; after 24-week treatment, 3 achieved SALT95, and 1 achieved SALT75 and then withdrew baricitinib for personal reasons; after 36-week treatment, 3 achieved SALT99, and then received half-dose treatment; after 48-week treatment, 1, 1, 1 and 1 patient achieved SALT99, SALT83, SALT31, and SALT0, respectively, and 2 of them experienced gradually aggravated hair loss 1 - 2 months after the start of half-dose treatment. Among the 3 children with complicated nail damage, the improvement rates of nail severity index scores were 67.5%, 45.4%, and 25% respectively, and the improvement rates of toenail severity index scores were 42.5%, 71.4%, and 5% respectively after 12-week treatment; after 48-week treatment, the improvement rate of nail severity index scores were 100%, 100%, and 50% respectively, and the improvement rate of toenail severity index scores were 96.2%, 100%, 50% respectively. During the treatment, the uric acid level increased in 2 children, and one of them was accompanied by increased serum levels of low-density lipoprotein cholesterol and high-density lipoprotein cholesterol; 1 suffered from respiratory tract infections twice during the treatment, and was recovered after symptomatic treatment; there were no adverse reactions leading to drug withdrawal.Conclusion:JAK inhibitors can be used as a treatment option for severe alopecia areata in children.

Tinnitus refers to the perception of abnormal sound in the absence of external sound stimulation. It can have an impact on a person's mood, memory, attention, and mental state, although the mechanism of tinnitus is still unclear. In recent years, the research on the central neural mechanism of tinnitus has attracted the attention of scholars.Functional magnetic resonance imaging （fMRI）,as an effective imaging technology, has been actively employed in this field. This paper provides a systematic summary of studies on the central neural mechanism of tinnitus by fMRI in recent years,revealed the changes of functional connections among tinnitus-related neural networks,such as auditory network,limbic system,default mode network and salience network. The central neural mechanism of tinnitus involves multiple networks that interact with each other. By understanding this mechanism, we hope to develop more targeted prevention and treatment strategies to help patients alleviate long-term tinnitus.
