Objective To investigate the value of cranial CT cisternal grading combined with D-dimer(D-D)and Glasgow Coma Scale(GCS)score in predicting the short-term postoperative prog-nosis of patients with severe traumatic brain injury.Methods A total of 165 patients with severe trau-matic brain injury who were treated in the hospital from January 2019 to May 2024 were selected as study subjects,all underwent craniotomy surgery.Postoperative follow-up was conducted for 3 months to analyze the differences in clinical data and preoperative indicators such as cranial CT cisternal grad-ing,D-D levels,and GCS scores between patients with poor and good prognosis.The value of cranial CT cisternal grading,D-D levels,and GCS scores in predicting short-term postoperative poor prognosis in patients with severe traumatic brain injury was also analyzed.Results Compared with patients with good prognosis,patients with poor prognosis had higher proportion of age,cranial CT cisternal grading of Ⅰ to Ⅱ,D-D levels,and GCS scores＜6(P＜0.05).There were no statistically significant differences in C-reactive protein,prothrombin time,activated partial thromboplastin time,international normalized ratio,total cholesterol,triglycerides,high-density lipoprotein cholesterol,and low-density lipoprotein cholesterol levels between patients with poor and good prognosis(P＞0.05).Cranial CT cisternal grading,D-D levels,and GCS scores were influencing factors for short-term postoperative poor prognosis in patients with severe traumatic brain injury(P＜0.05).The area under the curve for poor prognosis by three indicators in combination was 0.941(95％CI,0.906 to 0.975),which was higher than the area under the curve for the individual predictions of cranial CT cisternal grad-ing,D-D levels,and GCS scores(P＜0.05).Conclusion The influencing factors for short-term postoperative prognosis in patients with severe traumatic brain injury include cranial CT cisternal grading,D-D levels,and GCS scores.The model based on these three indicators has certain appli-cation value in predicting patient prognosis.

Objective To investigate the relationships of serum microRNA-9-3p(miR-9-3p),microRNA-27b-3p(miR-27b-3p),with brain glioma(BG)grading and their impacts on prognosis.Methods A total of 172 BG patients admitted in Suqian Hospital of Jiangsu Provincial People's Hos-pital from May 2020 to May 2023 were enrolled and divided into high-grade group(grade Ⅲ to Ⅳ,n=101)and low-grade group(grade Ⅰ to Ⅱ,n=71)according to the World Health Organization(WHO)classification of central nervous system tumors.Additionally,85 healthy individuals of the same age range during the same period were selected as control group.General information,serum levels of miR-9-3p,and miR-27b-3p were compared among the three groups.The correlations of pre-treatment serum levels of miR-9-3p and miR-27b-3p with BG grading were analyzed.The prognosis of BG patients one year after treatment was recorded,and clinical data were compared between the poor prognosis group and the good prognosis group.Factors influencing poor prognosis in BG patients as well as the value of pretreatment serum miR-9-3p and miR-27b-3p in predicting poor prognosis were analyzed.Conventional factors influencing poor prognosis were used to establish a conventional prediction mod-el,and model combined with pretreatment serum miR-9-3p and miR-27b-3p levels was used as a new prediction model.The value of these two models in predicting poor prognosis in BG patients was compared.Results Before treatment,serum levels of miR-9-3p and miR-27b-3p were lower in the high-grade group than those in the low-grade and control groups,and lower in the low-grade group than those in the control group(P＜0.05).Correlation analysis showed that pretreatment serum levels of miR-9-3p and miR-27b-3p were negatively correlated with BG grading(r=-0.573,P＜0.001;r=-0.498,P＜0.001),and serum miR-9-3p level was positively correlated with miR-27b-3p level in BG patients(r=0.509,P＜0.05).Before treatment,the poor prognosis group had a higher proportion of patients with WHO grade Ⅲ to Ⅳ,low differentiation,Karnofsky Performance Scale(KPS)＜70,and higher serum interleukin-17(IL-17)levels compared to the good prognosis group,while serum levels of miR-9-3p and miR-27b-3p were lower(P＜0.05).Logistic regression analysis showed that pretreatment WHO grading,differentiation,KPS,serum IL-17,miR-9-3p,and miR-27b-3p levels were all influencing factors of poor prognosis in BG patients(P＜0.05).Receiver operating characteristic(ROC)curves showed that the areas under the curve(AUCs)for pretreatment serum miR-9-3p and miR-27b-3p alone in predicting poor prognosis in BG patients were 0.714 and 0.720,respectively,with no statistically significant difference(Z=0.086,P=0.413).The AUC of the conventional prediction model for predicting poor prognosis in BG patients was 0.829,and the AUC of the new prediction model was 0.926(P＜0.05).Conclusion Serum levels of miR-9-3p and miR-27b-3p are negatively correlated with BG grading and are factors influ-encing poor prognosis,demonstrating certain value in predicting poor prognosis.

Objective To explore the biomechanical responses of the cupula of the human semicircular canal to three basic rotational perception processes.Methods A one-dimensional visual semicircular canal model was successfully fabricated using three-dimensional printing and hydrogel physical cross-linking technologies,and the response deformation of the cupula was explored by applying constant angular velocity,constant angular acceleration,and sinusoidal oscillation stimulations.Results The time constant of the biomimetic semicircular canal model was stable at approximately 3 s and close to the human time constant.The displacement deformation of the ampullary cupula was proportional to the angular acceleration applied.Under sinusoidal oscillation stimulation of 0.07-5.00 Hz,the gain of the semicircular canal increased from 1.54 um/° rises to 42.34 μm/°,but the phase difference decreased from 109.72° to 11.27°.Conclusions The biomimetic semicircular canal model prepared in this study can accurately simulate the working mechanism of the human semicircular canal and is expected to play a role in mechanism research and disease diagnosis of the human vestibular semicircular canal.

Objective:To conduct a scoping review on the application of sedentary behavior intervention in chronic disease patients and identify the delivery carriers, intervention time, intervention content and intervention results, so as to provide guidance for health care personnel to carry out relevant intervention research.Methods:Literature was systematically searched in PubMed, Embase, CINAHL, Cochrane Library, China National Knowledge Infrastructure and Wanfang data from establishment of the databases to June 15, 2023. The included literatures were screened, summarized and analyzed.Results:A total of 25 articles were included, among which the delivery carriers of sedentary behavior intervention included offline guidance, wearable device monitoring, telephone follow-up, mobile phone applications, email and website platform. The most common intervention implementers were rehabilitation therapists, followed by nurses, doctors and psychologists. Intervention durations ranged from 4 weeks to 3 years. Behavioral intervention strategies covered eight aspects, including providing information about behavioral consequences, goal setting, action planning, obstacle identification/problem-solving, behavioral feedback, exploring social support, motivational rewards and restructuring the physical environment. The types of outcome indicators for intervention included sedentary time, physical activity time, physiological indicators, psychological indicators, feasibility evaluation and safety evaluation. The results showed that sedentary behavior intervention not only reduced sedentary behavior in patients with chronic diseases, but also affected their quality of life and self-efficacy.Conclusions:Sedentary behavior intervention has positive effects on sedentary behavior, physical activity, physical health and mental health of patients with chronic diseases. Future research should strengthen the development and application of mobile phone applications and strengthen environmental intervention to further improve the intervention effect.

Objective To investigate the allergen profiles of dust mite-sensitive allergic rhinitis patients in Dalian,and to lay the foun-dation for precise prevention and control of allergic rhinitis.Methods Clinical data of allergic rhinitis patients treated at Affiliated Zhongshan Hospital of Dalian University from January 2015 to December 2022 were collected.The allergen distribution spectrums were compared between different groups designated according to sex,age,allergen reaction level,combination of other allergens,and testing time.Results A total of 1 330 allergic rhinitis patients were included,among whom the total detection rate of dust mite allergy was 60.83%(n= 809),with 330(40.79%)of these having dust mite sensitization alone and 479(59.21%)having multiple sensitization.There were many kinds of allergens in multiple sensitization.Among those with dust mite allergy,all 20 combined allergens detected in this group were analyzed,and mugwort,cat hair,and common rinea grass were the top three allergens in combined sensitization,accounting for 64.52%.The number of other allergens combined with dust mite was mainly 1-3 species(88.73%),and a maximum of 10 allergens were simultaneously present.Patients with 1-3 other combined sensitivities were mainly reactive to respiratory allergens,and those with 4 or more allergens essentially had joint sensitization to respiratory and food allergens.As for the allergen reaction level,the dust mite sensitivity reaction was relatively strong,with grade 3 or above accounting for 61.19%.Except for mugwort,the other combined allergens elicited mainly grade 1 and grade 2 reactions.The detection rates of dust mite allergy were 61.84%in male patients and 59.94%in female patients,with no statistical difference between the sexes(χ2=4.000,P= 0.261).The detection rate of dust mite sensitization was highest in the group aged<20 years and decreased with age(χ2=69.984,P<0.001).Dust mite-sensitive allergic rhinitis mainly occurred from August to October,and the detection rate of dust mite sensitization was the highest in October,reaching 80.16%.Conclusion The dust mite sensitization rate in patients with allergic rhinitis in the Dalian area is relatively high,and multiple sensitization is more common.Combinations of respiratory allergens mainly involve 1-3 types,and mugwort,cat hair,and common ragweed are the most common aller-gens combined with dust mite.Therefore,prevention and control of allergic rhinitis should focus on the characteristics of dust mite allergy in this region.

Objective:To compare the effect of interlocking intramedullary nail and locking plate in the treatment of varus proximal humeral fractures in the elderly.Method:A retrospective case-control study was conducted to analyze the clinical data of 46 elderly patients with varus proximal humeral fractures treated in Central Theater General Hospital of PLA from June 2016 to January 2019, including 27 males and 19 females, at age of 60-84 years［（71.9±5.7）years］. All fractures were fresh. Overall 25 patients were treated with interlocking intramedullary nail（intramedullary nail group）, and 21 patients were treated with locking plate（bone plate group）. The incision length, operation time, intraoperative bleeding and fracture healing time were compared between the two groups. Visual analogue scale（VAS）was used to evaluate the degree of pain relief at 1 week and 1 month after operation, and Constant-Murley score was used to evaluate the recovery of shoulder function at 1 month, 3 months and 1 year after operation. The cervical trunk angle was recorded at 2 days and 1 year after operation to judge whether there was a loss of cervical trunk angle. Postoperative complications were observed.Results:All patients were followed up for 12-32 months［（19.7±6.6）months］. The incision length［（7.1±0.6）cm］, operation time［（60.8±5.2）minutes］, intraoperative bleeding［（64.4±8.4）ml］and fracture healing time［（10.0±1.0）weeks］in intramedullary nail group were significantly less than those in bone plate group［（13.6±0.9）cm,（80.2±8.1）minutes,（151.0±15.2）ml,（11.0±1.5）weeks］（ P<0.05）. In both groups, the VAS decreased significantly over time, and markedly increased Constant-Murley score was detected as well（ P<0.05）. The VAS in intramedullary nail group［（2.8±0.2）points,（1.1±0.2）points］was significantly lower than that in bone plate group［（4.0±0.2）points,（1.5±0.1）points］at 1 week and 1 month after operation（ P<0.05）. The Constant-Murley score in intramedullary nail group［（59.9±6.9）points,（79.1±6.8）points］was higher than that in bone plate group［（50.1±8.5）points,（73.6±8.4）points］at 1 month and 3 months after operation（ P<0.05）, but the score showed no significant difference between intramedullary nail group［（89.1±5.3）points］and bone plate group［（86.4±6.4）points］at 1 year after operation（ P>0.05）. According to Constant-Murley score, 10 patients were evaluated as excellent and 15 patients as good in intramedullary nail group at 1 year after operation, with the excellent and good rate of 100%, while 8 patients were evaluated as excellent, 11 patients as good and 2 patients as fair in bone plate group at 1 year after operation, with the excellent and good rate of 91%（ P>0.05）. The cervical trunk angle in intramedullary nail group［（140.2±2.9）°,（139.6±2.3）°］had significant difference from that in bone plate group［（139.6±3.2）°,（138.8±3.3）°］at 2 days and 1 year after operation（ P<0.05）. In both groups, the cervical trunk angle had slight lost at 1 year after operation compared with that at 2 days after operation, but the difference was not statistically significant（ P>0.05）. In intramedullary nail group, 1 patient had subacromial impact. In bone plate group, 1 patient had screw cutting, 2 patients subacromial impact, and 2 patients delayed fracture healing. The incidence of complications in intramedullary nail group was 4%（1/25）, lower than 24%（5/21）in bone plate group（ P<0.05）. Conclusion:Compared with locking nail plate, interlocking intramedullary nail in the treatment of senile varus proximal humeral fracture has the advantages of small trauma, early fracture healing, less pain, early function recovery and less complications.
