Objective:In order to reduce the trauma associated with fetal cardiopulmonary bypass(F-CPB), Our team plans to develop a minimally invasive F-CPB through a small incision in the right axilla. The efficacy of this technique will be verified by using a big experimental animal model, thereby laying the foundation for fetal cardiac surgery supported by F-CPB in the future.Methods:Ten pregnant sheep were divided into F-CPB group(n=5) and control group(n=5). After fasting for 24 h, fetal lambs in the F-CPB group underwent a right axillary incision to establish F-CPB running for 1 h; The control group of fetal lambs only expose heart 1 h without F-CPB. Collect blood sample for laboratory test at the CPB vehicle before(T0), 30 min(T1), and 1 h after F-CPB running(T2) for the F-CPB group and through Superior Vena Cava before(T0), 30 min(T1), and 1 h after F-CPB running(T2) for the control group.Results:The blood routine indicators such as RBC, HCT, and Hb in the F-CPB group of fetal lambs decreased significantly during F-CPB, and their distribution showed significant statistical differences compared with the control group( P<0.05). There were no significant statistical differences in blood gas indicators such as pH, PO 2, PCO 2, and lactate concentration between the F-CPB group and the control group( P>0.05). There was no statistically significant difference in the concentration of cTnI in fetal lamb serum at each time point( P>0.05). There were significant statistical differences( P<0.05) in the distribution of fetal lamb Alb, γ-GGT, CK concentration and cholesterol concentration at various time points in the F-CPB group compared with the control group in liver function examination. In addition, the distribution of BUN in fetal lambs showed a significant difference between the two groups( P=0.006). Conclusion:A minimally invasive F-CPB via small incision in the right axilla is safe and feasible. The experimental animal model has demonstrated that this technique has minimal impact on the vital organ functions and internal environment of fetal lambs, thereby laying the foundation for clinical fetal cardiac surgery in the future.

Objective: To investigate associations of suicidal ideation with clinical features, inflammatory markers, and thyroid hormones in patients with schizophrenia. Methods: The subjects of this study were 203 schizophrenic patients, grouped on the basis of suicidal ideation. Clinical characteristics were assessed using multiple scales. Neutrophil to lymphocyte ratio(NLR), platelet to lymphocyte ratio(PLR), monocyte to lymphocyte ratio(MLR) and thyroid hormones were also detected. SPSS 23.0 was used for statistical analyses. Results : The prevalence of suicidal ideation was 21.7% in patients with schizophrenia. Logistic stepwise regression analyses showed that Calgary depression scale(CDSS) total score(OR=1.490, 95%CI=1.287-1.724,P<0.001), insomnia severity index scale(ISI) total score(OR=1.096, 95%CI=1.011-1.187,P=0.025), modified overt aggression scale(MOAS) total score(OR=1.111, 95%CI=1.016-1.215,P=0.021), MLR(Ln)(OR=15.123, 95%CI=3.868-59.125,P<0.001), and triiodothyronine(T3)(OR=0.037, 95%CI=0.003-0.388,P=0.006) were the independent influences of suicidal ideation. Additionally, receiver operating characteristic(ROC) curve analyses revealed that the five-item combination of CDSS total score, ISI total score, MOAS total score, MLR(Ln), and T3(AUC=0.908, 95%CI=0.867-0.949,P<0.001) had better ability to identify suicidal ideation. Conclusion The risk of suicidal ideation is relatively high in patients with schizophrenia, and there may be stronger associations between suicidal ideation and depression, insomnia, aggression, MLR, and T3.

ObjectiveTo study the relationship between qi stagnation constitution and suboptimal health status (SHS) or lifestyle.MethodsFrom 2012 to 2013, we conducted a cross-sectional survey of 24 159 Chinese individuals aged 12–80 years. The qi stagnation constitution was assessed using the Constitution in Chinese Medicine Questionnaire. Health status was evaluated through medical records and the Subhealth Measurement Scale V1.0 (SHMS V1.0). Health-promoting lifestyles were measured using the Health-Promoting Lifestyle Profile II (HPLP-II).ResultsOf the 24 159 participants, 16.1% and 15.2% were classified as “always” and “sometimes” having the qi stagnation constitution, respectively. Those classified as “rarely” having the qi stagnation constitution scored higher on both the HPLP-II and SHMS V1.0. The participants classified as “always” having the qi stagnation constitution showed a significant association with SHS or disease compared to other imbalanced constitutions. Those in the “always” category were approximately 21 times more likely to be classified as having SHS (odds ratio [OR]: 21.17, 95% confidence interval [CI]: 15.74–28.45), whereas those in the “sometimes” category were approximately six times more likely (OR: 5.89, 95% CI: 5.04–6.90). Accordingly, the qi stagnation constitution score was significantly associated with the diagnosis of SHS, with an area under the curve of 0.77 (P .001). A score of 18.75 yielded the highest Youden Index (0.407), with a sensitivity of 60.5% and a specificity of 80.3%. Significant associations were observed between health-promoting lifestyles and qi stagnation constitution severity in an ordinal regression analysis (P .001). Protective factors included stress management (OR: 1.59), self-actualization (OR: 1.57), and exercise (OR: 1.36). In contrast, poorer interpersonal relationships (OR: 0.79), greater health responsibilities (OR: 0.86), and poorer nutrition (OR: 0.91) were associated with increased severity.ConclusionModulating the qi stagnation constitution through lifestyle interventions may help prevent the progression of SHS to disease, which aligns with core preventive principles in traditional Chinese medicine.

Objective:To construct a competency evaluation indicator system for infection prevention and control nurses in Operating Rooms (hereinafter referred to as "IPC") and provide an objective basis for the management of IPC nurses.Methods:From June to November 2022, an initial competency evaluation indicator system for IPC nurses was developed through literature review and semi-structured interviews. The Delphi method was employed to consult 20 experts from 11 provinces and municipalities across the country. Analytical Hierarchy Process (AHP) and mean distribution method were applied to quantify and determine the weight of each level of indicators within the system.Results:Nineteen experts were finally included, with two rounds of questionnaire recovery rates of 95.00% (19/20) and 100.00% (19/19), respectively. The authority coefficients of the experts were 0.858 and 0.861, familiarity coefficients were 0.850 and 0.853, and coefficients of judgment basis were 0.865 and 0.868, respectively. The Kendall's W coefficient of concordance for the two rounds of inquiries were 0.139 and 0.202 ( P<0.05), respectively. The final IPC nurse competency evaluation indicator system included six primary indicators, 22 secondary indicators, and 66 tertiary indicators. Conclusions:The constructed IPC nurse competency evaluation indicator system is scientific, reasonable, objective, and comprehensive, providing a valuable reference for the capability training, assessment, entry standards, and qualification certification of IPC nurses.

Objective To understand the molecular epidemiological characteristics of Norovirus outbreaks and the genome evolution of Norovirus epidemic strains in Hainan Province from 2020 to 2022.Methods The information and samples have been collected from the norovirus outbreaks from 2020 to 2022.Norovirus was detected by using the real-time PCR in these samples,then the detected sequences were amplified the analyzed.The Norovirus se-quences of 8 strains had been amplified and analyzed.Results From 2020 to 2022,39 gastroenteritis outbreaks were reported,and 25 outbreaks caused by Norovirus which mainly occurred in childcare institutions and schools(20/25,80％).The Norovirus outbreaks were mainly concentrated in counties around Haikou(northeast),which including Ding'an(5 cases),Wenchang(4 cases),Chengmai(4 cases),and Lingao(3 cases);following by western regions which included Baisha(2 cases),Ledong(2 cases),and Dongfang(3 cases).1 case was in Wanning in the southeast.Among individuals aged 2-17,the positive proportion of Norovirus in males was higher than that in females.Among individuals aged over 55,the proportion of Norovirus positive in females was higher than that in males.The gender of positive samples among individuals aged 18-40 was related to their profession.According to RT-PCR typing and sequencing,GⅡ group Norovirus were classified in13 outbreaks.There were 4 genotypes detected.GⅡ.2[P1 6]was the main epidemic strain with 60％(9/13),and the other three genotypes were GⅡ.4 Sydney[P31](15.4％,2/13)GⅡ.4 Sydney[P16](7.7％,1/13)and GⅡ.3[P12](7.7％,1/13).Further genic analysis of 8 Norovirus strains showed that all of them were still in the same branch as the previ-ous strain,and all exhibited a certain amount of amino acid variation.Conclusion Norovirus is the main pathogen of gastroenteritis outbreaks in Hainan province,and the main epidemic strain is GⅡ.2[P16].It is necessary to continue to strengthen the monitoring that provides scientific evidence for the prevention and control of norovirus out-breaks in Hainan region.

BACKGROUND:Atlantoaxial dislocation,because of its high difficulty and high risk of surgery,has been regarded as the"surgical restricted area"by the international orthopedic community.However,with the rapid development of intelligent digitization in orthopedics,robot-assisted navigation screw placement technology has been widely used in clinical practice,which significantly reduces the difficulty and risk of surgery and improves the safety of surgery.However,there are few reports on the application of this technique in the treatment of atlantoaxial dislocation. OBJECTIVE:To explore the application value of robot-assisted pedicle screw internal fixation in the treatment of atlantoaxial dislocation. METHODS:The medical records of five patients with atlantoaxial dislocation treated with C1-C2 pedicle screw fixation under robot-assisted navigation in Zhuhai Hospital of Guangdong Provincial Hospital of Chinese Medicine from October 2021 to July 2022 were retrospectively analyzed.Operation time,length of neck incision,blood loss,postoperative drainage volume,and length of hospital stay were recorded.Attention should be paid to cerebrospinal fluid leakage,vertebral artery injury,nerve injury,operative area infection and other complications.The visual analog scale score of neck pain,the spinal cord injury grade of the American Spinal Injury Association,the cervical spine score of the Japanese Orthopaedic Association,and the imaging indicators were collected before surgery and at the last follow-up.Screw placement accuracy was assessed. RESULTS AND CONCLUSION:(1)Five patients were successfully completed surgery,without vascular,nerve injury or other complications,and were followed up for 12-20 months.(2)A total of 20 cervical pedicle screws were placed in 5 patients,including 9 type A screws,10 type B screws,and 1 type C screw.The accuracy of screw placement was 95%.(3)At the last follow-up,the visual analog scale score was(0.80±0.71)points,which was significantly lower than that before operation(4.00±2.83)points;the Japanese Orthopaedic Association score was(14.80±0.84)points,which was significantly higher than that before operation(8.00±0.71)points.Anterior atlantodental interval decreased from(7.86±3.25)mm to(2.82±0.93)mm;space available of the spinal cord increased from(6.74±1.99)mm to(12.10±3.51)mm;cervicomedullary angle increased from(133.32±13.55)° to(153.44±9.53)°;clivus-canal angle increased from(128.02±9.92)° to(143.25±12.99)°.The results of the last follow-up indexes were improved compared with those before operation,and the differences were significant(all P<0.05).(4)Postoperative imaging follow-up showed that all patients had bone fusion in the bone graft area,and no internal fixation loosening,fracture or pull-out occurred.(5)This method can avoid relying on the doctor's experience and hand feeling,ensure the accuracy of upper cervical screw placement,reduce the risk of surgery,and obtain satisfactory results in mid-term follow-up.
