Objective:To evaluate the application of digital visualization in preoperative planning for surgical clearance of vertebral infection lesions following percutaneous vertebroplasty (PVP).Methods:A retrospective study was conducted to analyze the 13 patients with infectious spondylitis following PVP who had undergone one-stage posterior debridement and interbody bone grafting combined with instrumentation at Department of Spinal Surgery, Zhengzhou Orthopaedics Hospital from January 2016 to December 2022. They were 4 males and 9 females with an age of (71.4±6.5) years. Before surgery, the CT raw data of the patients were imported into software Mimics to reconstruct a three-dimensional model of the spine. After the distribution of bone cement in the model and its relationships with the vertebral plate, pedicle, articular process, and spinal cord were observed, a safe area for spinal canal surgery was designed. Intraoperative operations were carried out according to the preoperative planning. Surgical time, intraoperative blood loss, improvements in American Spinal Injury Association (ASIA) grading, and postoperative complications were recorded. The therapeutic efficacy was evaluated by comparisons of erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), visual analogue scale (VAS), and Oswestry disability index (ODI) between preoperation, 2 weeks and 3 months postoperation, and the last follow-up.Results:Surgery went on successfully in all the 13 patients according to the preoperative planning. The surgical time was (275.9±28.3) min and the intraoperative blood loss (865.4±183.0) mL. All patients were followed up for (24.7±9.4) months. The levels of ESR, CRP, VAS, and ODI at 2 weeks, 3 months and the last follow-up were significantly lower than those before surgery ( P<0.05). At the last follow-up, X-ray and CT examinations showed good positions of internal fixation and sufficient bone graft fusion. The ASIA grading recovered from preoperative D to E in 5 patients. No incision infection, sinus formation, worsening of neurological symptoms, loosening or rupture of internal fixation, or worsening of neurological dysfunction were found. Conclusion:With the assistance of 3D visualization, the spinal cord, bone cement, and debridement area can be visualized directly to reduce nerve injury complications so that a safe and effective preoperative planning can be made for surgical clearance of vertebral infection lesions following PVP.

Fibromyalgia syndrome （FMS） is a refractory， chronic non-articular rheumatic disease characterized by widespread pain throughout the body， for which there are no satisfactory therapeutic drugs or options. There are rich Chinese medical therapies， and some non-drug therapies， such as acupuncture， Tai Chi， and Ba-Duan-Jin， have shown satisfactory efficacy and safety and definite advantages of simultaneously adjusting mind and body. FMS is taken as a disease responding specifically to traditional Chinese medicine （TCM） by the National Administration of Traditional Chinese Medicine in 2018. In order to clarify the research progress in FMS and the clinical advantages of TCM/integrated Chinese and Western medicine， the China Academy of Chinese Medicine organized a seminar for nearly 20 experts in Chinese and Western medicine， including rheumatology， psychology， acupuncture and moxibustion， and encephalopathy， with the topic of difficulties in clinical diagnosis and treatment of FMS and advantages of TCM and Western medicine. The recommendations were reached on the difficulties in early diagnosis and solutions of FMS， mitigation of common non-specific symptoms， preferential analgesic therapy， TCM pathogenesis and treatment advantages， and direction of treatment with integrated Chinese and Western medicine. FMS is currently facing the triple dilemma of low early correct diagnosis， poor patient participation， and unsatisfactory benefit from pure Western medicine treatment. To solve the above problems， this paper suggests that rheumatologists should serve as the main diagnostic force of this disease， and they should improve patient participation in treatment decision-making， implement exercise therapy， and fully utilize the holistic and multidimensional features of TCM， which is effective in alleviating pain， improving mood， and decreasing adverse events. In addition， it is suggested that FMS treatment should rely on both TCM and Western medicine and adopt multidisciplinary joint treatment， which is expected to improve the standard of diagnosis and treatment of FMS in China.

Objective·To explore the effect of continuous nursing based on EMS[environment management(E),medicine direction(M)and self monitoring(S)]management mode on the preschool children with asthmatic diseases.Methods·A total of 67 children aged 0 to 6 years with asthmatic diseases admitted to the Department of Respiratory Medicine,Shanghai Children's Hospital,Shanghai Jiao Tong University School of Medicine from December 2019 to November 2020 were selected and divided into observation group(33 cases)and control group(34 cases)according to the random number table method,with 3 cases lost,and finally 32 cases in each group.The observation group received continuous nursing care based on EMS management mode,while the control group received routine care and discharge follow-up through the telephone.The children in the two groups were followed up at 1,3,and 6 months after discharge to evaluate the results of Test for Respiratory and Asthma Control in Kids(TRACK)and wheezing recurrence;Medication Adherence Report Scale for Asthma(MARS-A)and Nursing Job Satisfaction Questionnaire were used to evaluate medication adherence and nursing job satisfaction 6 months after discharge.Results·There was no significant difference in demographic characteristics and clinical baseline characteristics between the two groups.Repeated measures analysis of variance showed that effects of time,groups and the interaction of groups×time on the total score of TRACK were statistically significant.The total scores of TRACK in the observation group were significantly higher than those in the control group at 1,3,and 6 months after discharge(P=0.000).The total scores of TRACK in the two groups gradually increased with time(P=0.000).The recurrence rates of wheezing in the observation group were 25.0%,18.7%,and 9.4%at 1,3,and 6 months after discharge,which were significantly lower than those in the control group(50.0%,43.7%,and 31.3%,respectively,P<0.05).Generalized estimating equation analysis showed that there was a statistically significant difference between the two groups(P=0.013),and the intervention effect of the observation group was better than that of the control group(OR=0.292).The MARS-A score of the observation group was 4.519±0.395 at 6 months after discharge,which was significantly higher than that of the control group(3.994±0.739,P=0.001).The nursing job satisfaction of the observation group was significantly higher than that of the control group(P=0.000).There was a moderate positive correlation between the MARS-A score and the nursing job satisfaction(r=0.389,P=0.001).Conclusion·Continuous nursing based on EMS management mode can significantly improve the medication compliance and wheezing control level of the preschool children with asthmatic diseases,significantly reduce the recurrence rate of wheezing,and improve the nursing satisfaction.

Objective To explore the neuroprotective effect of asiatic acid(AA)on brain damage after experimental subarachnoid hemorrhage(SAH)in rats.Methods A total of 108 adult SD rats were divided into the sham1 group,the SAH+vehicle group and the SAH+AA group,with 36 rats in each group.The 42 rats were divided into the sham2 group,3,6,12,24,48 and 72 h after SAH groups,with 6 rats in each group.Except the sham group,SAH model was established by unilateral external carotid artery puncture method in other groups.After modeling,the SAH+AA group was given AA solution(30 mg/kg)by gavage.Neurobehavioral changes were assessed by foot fault test and modified Garcia score.Western blot assay was used to detect the protein level of glutathione peroxidase 4(GPX4)in brain tissue.ELISA was used to detect the concentrations of glutathione(GSH)and malondialdehyde(MDA).Fluoro Jade B(FJB)staining was used to detect the neuronal death.Results Compared with the sham1 group,the SAH+vehicle group showed a significant increase in the proportion of empty steps and a significant decrease in the modified Garcia score,a significant decrease in GPX4 protein levels,a significant increase in MDA concentration(P＜0.05),a decrease in GSH concentration(P＜0.01)and a significant increase in the number of dead neurons(P＜0.05).Compared with the SAH+vehicle group,a significant decrease in the proportion of empty steps,a significant increase in the modified Garcia score,a significant increase in GPX4 protein level,a significant decrease in MDA concentration,a significant increase in GSH concentration(P＜0.05)and a significant decrease in the number of dead neurons in the SAH+AA group(P＜0.05).Conclusion AA may reduce brain injury after SAH in rats by inhibiting lipid peroxidation.

Objective:To investigate the value of CT radiomic model based on analysis of primary gastric cancer and the adipose tissue outside the gastric wall beside cancer in differentiating stage T1-2 from stage T3-4 gastric cancer.Methods:This study was a case-control study. Totally 465 patients with gastric cancer treated in Affiliated People′s Hospital of Jiangsu University from December 2011 to December 2019 were retrospectively collected. According to postoperative pathology, they were divided into 2 groups, one with 150 cases of T1-2 tumors and another with 315 cases of T3-4 tumors. The cases were divided into a training set (326 cases) and a test set (139 cases) by stratified sampling method at 7∶3. There were 104 cases of T1-2 stage and 222 cases of T3-4 stage in the training set, 46 cases of T1-2 stage and 93 cases of T3-4 stage in the test set. The axial CT images in the venous phase during one week before surgery were selected to delineate the region of interest (ROI) at the primary lesion and the extramural gastric adipose tissue adjacent to the cancer areas. The radiomic features of the ROIs were extracted by Pyradiomics software. The least absolute shrinkage and selection operator was used to screen features related to T stage to establish the radiomic models of primary gastric cancer and the adipose tissue outside the gastric wall beside cancer. Independent sample t test or χ2 test were used to compare the differences in clinical features between T1-2 and T3-4 patients in the training set, and the features with statistical significance were combined to establish a clinical model. Two radiomic signatures and clinical features were combined to construct a clinical-radiomics model and generate a nomogram. The area under the receiver operating characteristic curve (AUC) was used to evaluate the efficacy of each model in differentiating stage T1-2 from stage T3-4 gastric cancer. The calibration curve was used to evaluate the consistency between the T stage predicted by the nomogram and the actual T stage of gastric cancer. And the decision curve analysis was used to evaluate the clinical net benefit of treatment guided by the nomogram and by the clinical model. Results:There were significant differences in CT-T stage and CT-N stage between T1-2 and T3-4 patients in the training set ( χ2=10.59, 15.92, P=0.014, 0.001) and the clinical model was established. After screening and dimensionality reduction, the 5 features from primary gastric cancer and the 6 features from the adipose tissue outside the gastric wall beside cancer established the radiomic models respectively. In the training set and the test set, the AUC values of the primary gastric cancer radiomic model were 0.864 (95% CI 0.820-0.908) and 0.836 (95% CI 0.762-0.910), and the adipose tissue outside the gastric wall beside cancer radiomic model were 0.782 (95% CI 0.731-0.833) and 0.784 (95% CI 0.702-0.866). The AUC values of the clinical model were 0.761 (95% CI 0.705-0.817) and 0.758 (95% CI 0.671-0.845), and the nomogram were 0.876 (95% CI 0.835-0.917) and 0.851 (95% CI 0.781-0.921). The calibration curve reflected that there was a high consistency between the T stage predicted by the nomogram and the actual T stage in the training set ( χ2=1.70, P=0.989). And the decision curve showed that at the risk threshold 0.01-0.74, a higher clinical net benefit could be obtained by using a nomogram to guide treatment. Conclusions:The CT radiomics features of primary gastric cancer lesions and the adipose tissue outside the gastric wall beside cancer can effectively distinguish T1-2 from T3-4 gastric cancer, and the combination of CT radiomic features and clinical features can further improve the prediction accuracy.

Objective To investigate the epidemiological characteristics and mutation spectrum of monogenic diseases in Chinese population through a large-scale,multicenter carrier screening.Methods This study was conducted among a total of 33 104 participants(16 610 females)from 12 clinical centers across China.Carrier status for 223 genes was analyzed using high-throughput sequencing and different PCR methods.Results The overall combined carrier frequency was 55.58%for 197 autosomal genes and 1.84%for 26 X-linked genes in these participants.Among the 16 669 families,874 at-risk couples(5.24%)were identified.Specifically,584 couples(3.50%)were at risk for autosomal genes,306(1.84%)for X-linked genes,and 16 for both autosomal and X-linked genes.The most frequently detected autosomal at-risk genes included GJB2(autosomal recessive deafness type 1A,393 couples),HBA1/HBA2(α-thalassemia,36 couples),PAH(phenylketonuria,14 couples),and SMN1(spinal muscular atrophy,14 couples).The most frequently detected X-linked at-risk genes were G6PD(G6PD deficiency,236 couples),DMD(Duchenne muscular dystrophy,23 couples),and FMR1(fragile X syndrome,17 couples).After excluding GJB2 c.109G>A,the detection rate of at-risk couples was 3.91%(651/16 669),which was lowered to 1.72%(287/16 669)after further excluding G6PD.The theoretical incidence rate of severe monogenic birth defects was approximately 4.35‰(72.5/16 669).Screening for a battery of the top 22 most frequent genes in the at-risk couples could detect over 95%of at-risk couples,while screening for the top 54 genes further increased the detection rate to over 99%.Conclusion This study reveals the carrier frequencies of 223 monogenic genetic disorders in the Chinese population and provides evidence for carrier screening strategy development and panel design tailored to the Chinese population.In carrier testing,genetic counseling for specific genes or gene variants can be challenging,and the couples need to be informed of these difficulties before testing and provided with options for not screening these genes or gene variants.
