Objective To explore the effect of repetitive transcranial magnetic stimulation(rTMS)on the sleep disorder and examination results of recruits.Methods At a training base,the Pittsburgh Sleep Quality Index(PSQI)was used to screen the recruits with sleep disorders(total score of PSQI>7).The recruits were randomly assigned to rTMS group or sham rTMS group.Both groups received cognitive and behavioral intervention therapy,including sleep health education and relaxation training.Moreover,the rTMS group was treated with rTMS at the right posterior parietal lobe by continuous theta burst stimulation(cTBS)twice a day at an interval of at least 50 min for 5 consecutive days as a course of treatment with an interval of 2 days for a total of 2 courses of treatment.The coil position and stimulus intensity of sham rTMS group were consistent with the rTMS group,but the head of subjects was perpendicular to the coil plane and there was no effective stimulation.Before and after treatment,PSQI,self-rating depression scale,generalized anxiety disorder-7 and health questionnaire-15 were used to evaluate the sleep,mood and physical state of the recruits.The training result was assessed one month after treatment.The total effective rate of PSQI improvement and examination results were compared between the two groups.The independent influencing factors of excellent examination result were analyzed.Results Among 351 recruits,83 with sleep disorders completed treatment and follow-up.There were 40 patients in the rTMS group and 43 patients in the sham rTMS group.There was no significant difference between the two groups at baseline.After treatment,the total effective rate of PSQI improvement in the rTMS group was higher than that in the sham rTMS group(77.50%vs 53.49%,P=0.022).The average examination score and excellent rate of the rTMS group were higher than those of the sham rTMS group(91.58±3.19 vs 89.47±4.67,P=0.020;85%vs 65.12%,P=0.037).Logistic regression analysis showed that the treatment mode(rTMS group)was the independent influencing factor of excellent examination results(P=0.032).Conclusion rTMS can effectively and safely improve the sleep disorders and examination results of recruits.rTMS may play a positive role in improving the learning and training effect of recruits,which needs to be further proved.

Objective To explore the effects of sigma-1 receptor(Sig-1R)on brain function in rats after cardiopulmo-nary resuscitation and its protective role in brain injury.Methods Rats were randomly assigned to four groups with 20 in each:sham-operated control(sham group),6-hour post-resuscitation(PR 6 h group),12-hour post-resuscitation(PR 12 h group)and 24-hour post-resuscitation(PR 24 h group).In the latter three groups,cardiac arrest was induced by as-phyxiation,and cardiopulmonary resuscitation was performed 6 minutes after cardiac arrest.The rats were scored for neu-rological deficits at 6,12 and 24 hrs after resuscitation,respectively;after that,the rats were executed,and the expres-sion of Sig-1R protein,mitochondrial function index,and endoplasmic reticulum stress index apoptosis index were detec-ted by Western blot and immunohistochemistry.The correlation between Sig-1R and mitochondrial,endoplasmic reticulum stress and apoptosis indexes was evaluated.Results Compared with the sham-operated group,the rats in test group showed a gradual decrease in neurological deficit scores,Sig-1R protein expression,brain tissue adenosine triphos-phate(ATP)concentration and mitochondrial membrane potential(MMP)levels at 6,12,and 24 hrs of PR(P＜0.05);CHOP protein,activated cleaved caspase-12 and cleaved caspase-3 protein expression were consistently elevated(P＜0.05).In addition,Sig-1R was negatively correlated with brain tissue endoplasmic reticulum stress and apoptosis(P＜0.05)but positively correlated with mitochondrial membrane potential level(P＜0.05).Conclusions Sig-1R ex-pression in rat brain tissue correlates with brain injury after cardiopulmonary resuscitation and potential mechanism seems to be neuronal protection through modulating mitochondrial function and endoplasmic reticulum stress.

Objective : To investigate the expression and biological function of circular RNA(circRNA) hsa＿circ＿0002938 in gastric cancer. Methods : 45 pairs of tumor tissues and para-cancerous tissues from gastric cancer patients who underwent tumor reduction surgery at the hospital were collected. Human gastric cancer cells SGC-7901, BGC-823, HGC-27, MGC-803 and immortalized gastric mucosal epithelial cells GES-1 were routinely cultured. RT-qPCR was utilized to detect the expression of hsa＿circ＿0002938 in gastric cancer tissues and cells. Chi-square test was used to analyze its association with the clinicopathological characteristics of patients, and the Kaplan-Meier method was employed to assess the relationship between hsa＿circ＿0002938 expression levels and patient prognosis. The effects of hsa＿circ＿0002938 on the proliferation, migration and invasion abilities of gastric cancer cells were detected by CCK-8, scratch wound healing and Transwell assays. Bioinformatics was used to predict the miRNA and its downstream target genes that hsa＿circ＿0002938 might bind to. The competitive endogenous RNA regulatory network was constructed and the functions of the target genes were enriched. Results : The expression of hsa＿circ＿0002938 in gastric cancer tissues and cells was much higher than that in para-cancerous tissues and GES-1 cells(P<0.05). By contrast, patients in the high hsa＿circ＿0002938 expression group had significantly shorter 2-year progression-free survival than that in the low expression group after surgery(P<0.01). Moreover, knocking down the expression of hsa＿circ＿0002938 reduced the proliferative, migratory, and invasive abilities of gastric cancer cells(P<0.05). Bioinformatics predictive analysis showed that hsa＿circ＿0002938 could bind to hsa-miR-342-3p and hsa-miR-503-5p. The downstream target genes of miRNA were involved in several cancer-related pathways, like mitogen-activated protein kinase(MAPK), hippo and Wnt signaling pathway. Conclusion Hsa＿circ＿0002938, which is highly expressed in gastric cancer tissues and cells, is closely associated with poor patient prognosis. Knockdown of hsa＿circ＿0002938 inhibits the proliferation, migration, and invasion abilities of gastric cancer cells. The study reveals the potential role of hsa＿circ＿0002938 in the progression of gastric cancer, offering new insights into its prevention and treatment.

AIM:To investigate whether casein kinase 2(CK2)/calmodulin(CaM)/small-conductance Ca2+-activated K+channel type 2(SK2)signaling pathway mediates autophagy-induced sympathoexcitation in the paraventricu-lar nucleus(PVN)of rats with chronic heart failure(CHF).METHODS:We randomly divided 180 Wistar rats,aged 6 to 8 weeks,into 10 groups:sham+dimethyl sulfoxide(DMSO),sham+artificial cerebrospinal(aCSF),CHF+DMSO,CHF+aCSF,CHF+rapamycin(RAPA),CHF+3-methyladenine(3-MA),CHF+5,6-dichlorobenzimidazole riboside(DRB),CHF+calmidazolium chloride(CMDZ),CHF+N-cyclohexyl-N-[2-(3,5-dimethyl-1H-pyrazol-1-yl)-6-methyl-pyrimidin-4-yl]-amine(CyPPA),and CHF+apamin groups.We measured cardiac function,hemodynamic parameters,anatomic indicators,and sympathetic drive indicators(n=18).Western blot was used to examine the protein levels of mi-crotubule-associated protein 1 light chain 3-II(LC3-II)/LC3-I,beclin-1,P62,CK2α,SK2,and phosphorylated CaM.The number of SK2-positive neurons was measured using immunofluorescence staining.The NG108 cells were randomly divided into 6 groups:DMSO,aCSF,RAPA,3-MA,RAPA+DRB,and RAPA+CMDZ groups.Radioisotope 32P-ATP pro-tein kinase activity assays were used to detect CK2 activity in cultured NG108 cells.We used Western blot to examine the protein levels of CK2α,SK2,and phosphorylated CaM.RESULTS:Compared with CHF rats treated with vehicle,CHF rats treated with RAPA or apamin exhibited increased sympathetic drive indicators,but decreased left ventricular ejection fraction and fractional shortening(P<0.01).However,CHF symptoms,including sympathoexcitation,were attenuated by 3-MA,DRB,CMDZ or CyPPA infusion into the PVN(P<0.01).In CHF rats,RAPA infusion into the PVN induced CK2 activity,up-regulated LC3-II/LC3-I,beclin-1,CK2α,and phosphorylated CaM levels,but down-regulated P62 and SK2 expression,as well as the number of SK2-positive neurons(P<0.05 or P<0.01).In CHF rats,infusion of 3-MA or DRB into the PVN decreased CK2 activity,and down-regulated phosphorylated CaM level(P<0.01).Infusion of 3-MA,DRB or CMDZ into the PVN up-regulated SK2 expression and the number of SK2-positive neurons(P<0.01).In cultured NG108 cells,RAPA induced CK2 activation and up-regulated the expression of CK2α and the phosphorylation of CaM,but down-regulated SK2 expression(P<0.01).Treatment with RAPA increased the level of phosphorylated CaM and down-regulated SK2 expression in cultured NG108 cells(P<0.01),which was inhibited by DRB and CMDZ(P<0.05 or P<0.01).CONCLUSION:In rats with CHF,the CK2/CaM/SK2 signaling pathway in the PVN contributes to autophagy-induced sympathoexcitation.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Objective To observe the value of extracellular volume(ECV)and relative electron density(RED)based on dual-layer detector spectral CT(DLCT)for identifying colon cancer invasion into serous membrane.Methods Sixty-two patients with pathologically confirmed colon cancer with blurred pericolonic fat gap on CT images were retrospectively collected,including 18 cases of T4a stage tumors with serous membrane invasion and 44 cases of T2-T3 stage without serous membrane invasion.The arterial,venous and delayed phase DLCT images under 40 keV showing the largest diameter of colon cancers were analyzed.The iodine concentration(IC)and RED of the pericolonic fat around tumor-bearing and tumor-free intestines,as well as of the abdominal aorta or the common or external iliac artery were measured,while normalized IC(NIC)and difference of RED(REDdiff)of pericolonic fat around tumor-bearing and tumor-free intestines in each phase and ECV in delayed phase were calculated.The above parameters were compared between tumors with different stages,and for those with significant differences,the receiver operating characteristic curves were drawn,and the areas under the curve(AUC)were calculated to evaluate and compare the efficacies for identifying invasion of serous membrane in T4a stage colon cancer.Results Compared with T2-T3 stage colon cancers,T4a stage colon cancers were found more often occurred in patients aged ＜50 with higher proportion of lymph node metastases(both P＜0.05),also higher values of NIC and REDdiff on images in different phases,as well as ECV in delayed phase images(all P＜0.05).The AUC of arterial,venous and delayed phase NIC for differentiating T2-T3 and T4a stage colon cancers ranged from 0.868 to 0.902,while of REDdiff ranged from 0.848 to 0.903,all without significant difference(all P＞0.05).The AUC of delayed phase ECV was 0.948,not significant different with that of delayed phase NIC and REDdiff,arterial phase NIC nor venous phase REDdiff(all P＞0.05).Conclusion Based on DLCT,ECV and RED could be used to identifying serous membrane invasion of colon cancer when blurred pericolonic fat gaps were noticed.
