Objective:To explore the applied therapeutic effect of digital surgical technique combined with three dimensional(3D)printing guide plate in surgery of maxillofacial fracture.Methods:A total of forty patients with maxillofacial fracture who admitted to the Department of Stomatology at the First Medical Center of Chinese PLA General Hospital from June 2019 to June 2023 were selected.They were divided into an observation group(18 cases)and a control group(22 cases)based on different surgical methods.The observation group used digital technique combined with 3D printing technique to conduct surgery by auxiliary method,and the control group used routine open reduction and internal fixation surgery for maxillofacial fracture.The surgical time,bleeding volume,complications and satisfaction evaluation between two groups of patients were observed and compared.Results:All patients obtained clinical cure after open reduction and internal fixation surgery,and the surgical time(2.01±0.52)h and bleeding volume(123.89±67.31)mL during surgery of observation group were significantly lower than those of control group(U=62.000,26.500,P<0.05),respectively.The incidence of the complications in the observation group was significantly lower than that in the control group,and the difference was statistically significant(x2=4.675,P<0.05),and there were no statistically significant difference in infection and limited incision opening between the two groups(P>0.05).In the satisfaction evaluation,there was a significant difference in appearance satisfaction scores between the observation group(8.89±0.758)and the control group(7.73±0.827)(U=66.000,P<0.05),while there were no statistically significant differences in chewing and language aspects between two groups(P>0.05).Conclusion:The combination of digital technique and 3D printing guide plate has favorable clinical guidance effect in maxillofacial fracture surgery,which can significantly improve surgical efficacy,and reduce the incidence of complications,and obtain higher patient satisfaction.It is worth to be applied in clinical practice.

Objective:To analyze and summarize the clinical characteristics of mpox patients, thereby to rise clinicians′ awareness of severe mpox and provide a foundation for clinical diagnosis and treatment.Methods:The clinical data were retrospectively analyzed in 41 mpox patients treated at the Beijing You′an Hospital, Capital Medical University, from June to November 2023. Patients were categorized into mild and severe cases based on clinical manifestations, and laboratory results of the two groups were compared. Statistical analysis was performed using the Mann-Whitney U test. Results:The clinical manifestations of 41 mpox patients mainly included fever, rash and lymphadenopathy. Five patients with severe mpox might develop serious complications, including bacterial pneumonia, type Ⅰ respiratory failure, fungal infections, penile or perianal dry gangrene, penile soft tissue edema, intestinal obstruction, septic shock, perianal abscess, and necrotizing fasciitis. Patients with severe mpox had significantly higher white blood cell count (WBC), neutrophil count and C-reactive protein (CRP) level compare to those with mild cases (14.60(9.92, 24.08)×10 9/L vs 6.41(5.64, 8.37)×10 9/L, 12.43(7.02, 21.15)×10 9/L vs 3.35(2.46, 5.03)×10 9/L, 108.20(56.20, 124.10) mg/L vs 16.6(6.25, 49.98) mg/L), while the albumin level and CD4 + T lymphocyte count in the severe group were significantly lower compared to the mild cases (31.80(22.90, 35.15) g/L vs 44.70(42.90, 47.40) g/L, 24.00(12.00, 81.50)/μL vs 606.00(414.50, 767.50)/μL)). All these differences were statistically significant ( U=2.81, 3.02, 2.98, 3.56 and 3.26, respectively, all P<0.01). Conclusions:In clinical practice, clinicians should be vigilant for the possibility of severe mpox if patients exhibit a significant increase of WBC and CRP, a significant decrease in CD4 + T lymphocyte count, or if they develop severe complications.

The establishment of an intelligent audit system for hospital medical insurance is crucial for standardizing irrational practices and curbing the unwarranted escalation of medical insurance costs. A tertiary hospital has developed comprehensive prescription review rules in terms of indications, nutritional risk assessments, pain score evaluations, drug sensitivity test results, and target patient populations. When using medical insurance funds for settlement, both systematic and manual reviews are conducted, and three-level intervention measures such as " prompt, review, and interception" are implemented based on prescription issues. After the system was put into use, the hospital′s in-process information system supervision mode shifted from the previous focus on prompts to focus on audits. The medical insurance intelligent audit system provided timely prompts and interventions, and the number of unreasonable medical insurance prescriptions and deductions from medical insurance sampling prescriptions significantly decreased ( P<0.001), while the number of medical insurance medication prescription audits increased ( P<0.001). The application of the intelligent medical insurance medication audit system has improved the efficiency of prescription auditing and ensured the rationality of the use of medical insurance funds.

Objective To explore the correlation between personality traits and non suicidal self injury behavior in adolescent depression patients,in order to enhance understanding of the psychological health risks of depression patients.Methods This study was conducted at the Wuhan Mental Health Center from September 2021 to September 2023.A total of 138 patients with first-onset moderate to severe adolescent depression were included.The patients were divided into a group without self injury suicidal behavior(n=25),a non suicidal self injury(NSSI)group(n=78),and an attempted suicide(SA)group(n=35).Collect general information and data on neurotic personality scores,negative life events,emotional states,and social psychological factors using the Hamilton Anxiety Scale(HAMA),Hamilton Depression Scale(HAMD-24),and other psychological assessment tools.Using statistical methods for correlation and regression analysis to study the relationship between personality traits and non suicidal self injury behavior.Results There were significant differences in personality traits such as internal and external tendencies,psychoticism,neuroticism,and concealment among the non self injurious suicide behavior group,non suicidal self injurious behavior group,and suicide behavior group.The scores of the non suicidal self injurious behavior group and suicide behavior group were generally higher than those of the non self injurious self injurious behavior group(P<0.05);There were significant differences in self injury behavior scores among these three groups,especially in the suicide behavior group,which had the highest score,but there was no significant difference in life event scores;There were significant differences in scores for anxiety,depression,childhood trauma,stressful life events,and self-esteem among the three groups.Among them,the suicide behavior group had the highest scores for anxiety,depression,childhood trauma,and stressful life events,but the lowest score for self-esteem(P<0.05);Internal and external tendencies,psychoticism,neuroticism,and concealment are significantly correlated with non suicidal self injury behavior,and multiple regression analysis results show that these factors,as well as anxiety,depression,childhood trauma,stressful life events,and self-esteem,are inde-pendent influencing factors of non suicidal self injury behavior.The best predictive threshold for internal and exter-nal tendencies is-10.5%.Conclusion This study reveals the correlation between personality traits and non sui-cidal self injury behavior in adolescent depression patients.Understanding these relationships in clinical practice and intervention strategies can help better identify high-risk groups and provide personalized mental health support.

Objective:To analyze the long-term prognosis of IgA nephropathy (IgAN) with focal segmental glomerulosclerosis (FSGS) and the risk factors related to renal prognosis in children with IgAN-FSGS.Methods:A retrospective study was concluded in IgAN-FSGS children who were followed up for more than 5 years and diagnosed by renal biopsy for the first time in the Eastern Theater General Hospital from January, 2004 to December, 2018. The end-point events of the study were entering end-stage kidney disease (ESKD) or estimated glomerular filtration rate (eGFR) decreased by ≥50% from baseline, which were defined as poor renal prognosis. Baseline clinicopathologic data of IgAN-FSGS children were compared between the end-point event group and the non-end-point event group. The cumulative renal survival rate of IgAN-FSGS children was calculated by Kaplan-Meier survival analysis. The influencing factors of poor renal prognosis in IgAN-FSGS children were analyzed by Cox proportional hazards model, and the diagnostic value was evaluated by the receiver operating characteristic curve (ROC curve) and area under the curve (AUC). The diagnostic value was verified by time dependent-ROC and time dependent-AUC.Results:A total of 204 IgAN-FSGS children were enrolled in this study, of whom 132 cases were males (64.7%). The median age of renal biopsy was 16 (14, 17) years old. During a median follow-up time of 90.7 (71.7, 114.8) months, 57 cases (27.9%) reached the end-point events. Compared with the non-end-point event group ( n=147), the end-point event group ( n=57) had higher proportions of males and hypertension, higher levels of 24-hour urinary protein, serum creatinine, serum uric acid, urinary N-acetyl-β- D-glucosaminidase, urinary retinol binding protein, higher proportions of glomerular segmental sclerosis (S1) ≥25% and tubular atrophy/interstitial fibrosis (T1/T2), and lower levels of serum albumin, serum IgA, and serum IgG (all P<0.05). There was no statistical difference between the two groups in treatment (all P>0.05). Kaplan-Meier survival analysis showed that with entry of ESKD or eGFR decreased by ≥50% from baseline as the end-point events, the 5-year, 10-year, and 15-year cumulative renal survival rates in IgAN-FSGS children were 88.7%, 67.6%, and 50.7%, respectively. Multivariate Cox regression analysis showed that proteinuria >1 g/24 h ( HR=3.702, 95% CI 1.657-8.272, P=0.001), hyperuricemia ( HR=3.066, 95% CI 1.793-5.245, P<0.001), S1≥25% ( HR=2.017, 95% CI 1.050-3.874, P=0.035), T1/T2 ( HR=1.863, 95% CI 1.021-3.158, P=0.016) were the independent related factors for poor renal prognosis. ROC curve analysis showed that S1≥25% ( AUC=0.605, P=0.021, sensitivity 26.3%, specificity 94.6%), T1/T2 ( AUC=0.624, P=0.006, sensitivity 43.9%, specificity 81.0%), hyperuricemia ( AUC=0.658, P<0.001, sensitivity 52.6%, specificity 78.9%), proteinuria>1 g/24 h ( AUC=0.670, P<0.001, sensitivity 87.7%, specificity 46.3%) could accurately predict the renal outcome of IgAN-FSGS. Time dependent-ROC curve validation showed that the combined diagnosis of S1≥25%, T1/T2, hyperuricemia and proteinuria>1 g/24 h had a good predictive value for renal prognosis (3-year AUC=0.846 and 5-year AUC=0.777, respectively). Conclusions:During a median follow-up of 90.7 months, 27.9% of IgAN-FSGS children have poor renal prognosis, and the 5-year, 10-year, and 15-year cumulative renal survival rates are 88.7%, 67.6%, and 50.7%, respectively. Urinary protein >1 g/24 h, hyperuricemia, T1/T2, and S1 ≥25% are the risk factors for renal prognosis in IgAN-FSGS children.

To establish a disease risk prediction model based on genetic susceptibility genes and environmental risk factors， which can target high-risk population as early as possible， and intervene in the environmental risk factors in this population. Moreover， accurate screening of genetically susceptible populations can enhance the efficiency of health system. In recent years， with the maturation and cost reduction of high-throughput gene testing， gene testing has been widely used in individual clinical decision-making and will play a more important role in medical and health decision-making. The correlation between genetic testing and disease risk prediction is increasing， making it a prominent research topic in this field. This review summarizes the approaches for establishing and evaluating risk prediction models and discusses potential future challenges and opportunities.

In order to provide reference for the clinical application and basic research of Astragali Radix in neurodegenerative diseases.

Objective:To investigate the unqualified hepatitis C virus (HCV) detection result of blood donors from the served area of blood institutions.Methods:The data related to HCV markers detected of the first and repeat blood donors were collected from the system of practice comparison for the Chinese mainland blood institutions from 2017 to 2021. The anti-HCV reactive rate and the rates of anti-HCV negative but HCV-RNA reaction and all the relationship between rates and the annual, regional and different blood donors were statistically analyzed.Results:During 2017-2021, the number of anti-HCV reactive per 100 000 blood donors decreased from 444.3 to 250.44 in the served area of 22 blood institutions ( χ2=49.677, P<0.05). The number of HCV RNA detected positive per 100 000 anti-HCV negative increased from 0.69 to 2.05 year by year, but there was no statistical significance ( χ2=0.643, P>0.05). The anti-HCV unqualified rate was significantly different among regions ( χ2=3 260.283, P<0.05). The anti-HCV unqualified rate of the first blood donors was significantly higher than that of the repeated blood donors ( F=130.993, P < 0.05). The annual number of HCV RNA detected positive per 100 000 anti-HCV negative blood samples from donors ranged from 0 to 17.28. Conclusions:The anti-HCV unqualified rate of blood donors in the served area of 22 blood institutions decreased year by year. Compared with repeated blood donors, HCV infection should be emphasized in first-time blood donors. The implementation of HCV RNA test can detect out much more HCV infections and reduce the risk of transfusion transmitted infectious HCV.

Objective:To analyze the detection strategy and basic detection situation of markers of infectious diseases transmitted by transfusion in blood testing laboratories of blood stations in China.Methods:Based on the data of practice comparison working party of Blood Stations in Mainland of China from 2017 to 2021, the data on the testing strategies and the basic detection information of the markers for the transmission of infectious diseases through transfusion in the member laboratories of the practice comparison working party of Blood Stations in Mainland of China from 2017 to 2021 were collected, and the situation of the selection for testing markers, testing strategy and the testing method and other relevant aspects were sorted out and analyzed by charts.Results:The selection of the testing markers was consistent, but HTLV testing item was added in some member laboratories. The detection strategy of using two ELISA reagents and one nucleic acid testing (NAT) reagent simultaneously was adopted in 47 member blood stations; 3) NAT method was dominated by mini pool-NAT in member laboratories. The number of members adopting mini-pools of 8 (MP8)-NAT decreased from 17 in 2017 to 14 in 2021, while the number of members adopting mini-pools of 6 (MP6)-NAT increased from 13 in 2017 to 22 in 2021; Roche NAT system accounted for the largest proportion.Conclusions:In order to ensure blood safety and avoid missing detection, the blood stations still adopt the detection strategy of using two ELISA reagents and one nucleic acid testing (NAT) reagent simultaneously; Meanwhile, in order to increase the NAT positive rate, the proportion of mini pool-NAT mainly decreased year by year despite its dominating role, while the proportion of individual donation-NAT increased year by year; NAT method is transiting from mini-pools of 8 (MP8) to mini-pools of 6 (MP6); The proportion of imported NAT system used in NAT laboratory is relatively large.

Objective:To analyze the clinical effects of fecal microbiota transplantation (FMT) on the treatment of acute intestinal pseudo obstruction (AIPO) secondary to intracerebral hemorrhage.Methods:The clinical data of a patient with AIPO secondary to intracerebral hemorrhage who was admitted to Nanfang Hospital of Southern Medical University was analyzed. The flora compositon between donor and patient was compared, finding the changes of intestinal flora before and after FMT (day 0 and day 25).Results:The main clinical findings in the patient were serious bloating, expansion of the intestinal canal and intra-abdominal hypertension. A week of conventional therapy was not effective, and the symptoms became progressively worse, affecting respiratory function.The result of fecal flora suggested the intestinal microbiota dybiosis, so FMT was attempted. After FMT, the patient's gastrointestinal symptoms were significantly relieved, and there were no further episodes within 25 days. The new result of fecal flora showed that the flora colonizing the intestine was dominated by Akkermansia and Bifidobacterium, with a significant decrease in potential pro-inflammatory and gas-producing bacteria and an increased gut microbiota diversity. The results trended to be partly consistent with the donor at 25 days after FMT: at the phylum level, the relative abundance of Bacterioidetes, Vereucomicrobia, Firmicutes and Actinobacteria were increased while Proteobacteria was decreased; at the class level, the relative abundance of Verrucomicrobiae, Bacterioidia, Actinobacteria, Coriobacteriia and Clostridia were increased and Gammaproteobacteria was decreased; at the order level, the relative abundance of Bacterioidales, Verrucomicrobiales, Clostridiale, Coriobacteriales were increased and Betaproteobacteriales, Enterobacteriales were decreased; at the family level, the relative abundance of Bifidobacteriaceae, Akkermansiaceae, Ruminococcaceae were increased and Enterobacteriaceae was decreased; at the genus level, the relative abundance of Akkermansia, Bifidobacterium were increased and Escherichia-Shigella, Klebsiella were decreased. At 1-year follow-up, the patient lived with self-care and scored 5 points in Glasgow outcome scale (GOS). Conclusions:FMT may provide clinical benefit in treated patients with AIPO secondary to intracerebral hemorrhage, probably by regulating the intestinal microflora, and re-establishing proper intestinal barrier, to maintain intestinal homeostasis.
