The changes of PAF activity and the effects of anisodamine (654-2) were studied in the superior mesenteric artery occlusion (SMAO)shock in rabbits. The results showed that plasma PAF activity increased from 3.88?0.82 AU/ml before SM-AO to 9.71?1.26 AU/ml (P

BACKGROUND: Preplant diagnosis and rigorous implant strategy based on multislice spiral computed tomography (MSCT) imaging can improve success rate of mini-implants as anchorage. Effective application of imaging information in implant anchorage requires reliable tools and methods.OBJECTIVE: To investigate the accuracy of the radiographic and tunnel-type surgical templates assisting implant anchorage surgery and evaluate the clinical significance.METHODS: The transparent radiographic templates were made with occlusal rest to assist MSCT to scan two pigs' skulls locatively. After designed the implant anchorage angles in MSCT images accurately, we made the tunnel-type surgical template by angle data. A total of 32 miniscrews were implanted by surgical template, and the two pigs skulls were rescanned by MSCT. After dissected the pig alveolar process, the MSCT preoperative planning angles, the MSCT postoperative measurement angles and the measurement angles of anatomic bone samples were analyzed statistically. RESULT AND CONCLUSION: The 32 miniscrews were implanted successfully. They did not damage dental roots or surrounding important structures. Compared MSCT preoperative planning angles with MSCT postoperative measurement angles and anatomic bone samples measurement angles, there were no significant differences on axial sections or cross-sections and the r concordance correlations were very good. Results show that the radiographic and the tunnel-type surgical templates are accurate and reliable for operation and will help to improve the success rate of implant anchorage.

Radiation-induced brain injury is a serious untoward effect of radiotherapy for malignant tumors. Patients received radiotherapy frequently occur cognitive dysfunction which seriously affects the quality of life. Although the exact mechanisms regarding radiation-induced cognitive dysfunction remain unclear, prevention strategies targeting cognitive dysfunction are increasingly applied to clinical intervention, including whole brain radiotherapy with hippocampus avoidance, stereotactic radiosurgery in patients with multiple brain metastases, and pretreatment with neuroprotective drugs such as memantine and donepezil. In addition, measures including appropriate radiotherapy management models, regular cognitive tests, and therapeutic measures at the appropriate time are critical to improve the quality of life for brain tumor patients.

Objective: To investigate the level and influencing factors of mental health literacy among middle school students in Taizhou City, Zhejiang Province, so as to provide the basis for the development of mental health education and intervention. Methods: Middle school students were selected from six counties (districts) in Taizhou City using the random cluster sampling method. Demographic information, disease history, learning status, and relationship with parents were collected through questionnaire surveys. The level of mental health literacy was investigated using the Structured Mental Health Literacy Questionnaire for Middle School Students. The influencing factors for mental health literacy was analyzed using a multiple linear regression model. Results: A total of 7 173 middle school students were surveyed, including 4 273 junior high school students (59.57%) and 2 900 high school students (40.43%), and had a mean age of (15.52±1.49) years. There were 3 644 male students (50.80%) and 3 529 female students (49.20%). The median score of mental health literacy was 83.00 (interquartile range, 23.00) points. Multiple linear regression analysis revealed that older age (β'=0.074), female gender (β'=0.038), living in urban areas (β'=0.029), good family economic status (β'=0.061), engaging in sports (β'=0.122), having a good relationship with the father (β'=0.128), and having a good relationship with the mother (β'=0.094) were associated with higher mental health literacy scores among middle school students; while having a history of disease (β'=-0.144) and learning difficulties (β'=-0.178) were associated with lower mental health literacy scores. Conclusion The level of mental health literacy among middle school students in Taizhou City is relatively good, and is influenced by demographic characteristics, disease history, sports participation, learning and relationships with parents.

Objective: To investigate the mental health status and its influencing factors among guardians of patients with severe mental disorders, so as to provide the evidences for improving mental health services among guardians. Methods: The first guardians of patients with severe mental disorders registered and managed in Zhujing Township, Jinshan District, Shanghai Municipality were enrolled. Participants' demographics, economic status, health status and relationships with patients were collected using self-designed questionnaires from January to June 2021. Participants' mental health was assessed with twelve-item General Health Questionnaire (GHQ-12), and factors affecting guardians' mental health were identified with a multivariable logistic regression model. Results: A total of 650 questionnaires were allocated, and 606 valid questionnaires were recovered, with an effective recovery rate of 93.23%. The participants included 356 men (58.75%), and had a mean age of (59.61±12.61) years. Among all participants, 256 were patients' spouse (42.24%), and 516 lived with patients (85.15%). The mean GHQ-12 score was (3.18±2.48), and there were 171 participants with mental health problems (28.22%). Multivariable logistic regression analysis identified educational level of junior high school and below (OR=2.715, 95%CI: 1.076-6.850), married (OR=0.374, 95%CI: 0.184-0.761), patients' parents (OR=0.303, 95%CI: 1.114-0.806), living with patients (OR=0.481, 95%CI: 0.237-0.974), having basic medical insurance for urban employees (OR=0.489, 95%CI: 0.254-0.942), receiving government subsidy (OR=3.788, 95%CI: 1.734-8.276), self-rated health status (good, OR=0.105, 95%CI: 0.037-0.299; average, OR=0.126, 95%CI: 0.049-0.325), considering that caring patients has an impact on family (OR=3.689, 95%CI: 1.807-7.531), being hopeful about the patient's future (OR=0.372, 95%CI: 0.139-0.994) and patients' need for accompanying/surrogate care (OR=1.606, 95%CI: 1.006-2.565) as factors affecting mental health among guardians of patients with severe mental disorders. Conclusion Mental health problems are found among 28.22% of guardians of patients with severe mental disorders, and the development of mental health problems is affected by educational level, economic status, health status and patient's need of caring.

Objective To evaluate the effects of fraction of inspired oxygen (FiO2) and positive end-expiratory pressure (PEEP) on the gradient between arterial and end-tidal carbon dioxide (D(a-ET)CO2).Methods Sixty ASA Ⅰ or Ⅱ patients (body mass index ＜ 30 kg/m2),aged 25-50 yr,weighing 45-75 kg,scheduled for elective gynecological laparoscopic surgery,were randomized into A,B and C groups (n =20 each).The patients were mechanically ventilated with pure oxygen in group A,and with air and O2 (FiO2 =50％) in groups B (PEEP =0) and C (PEEP =5 cm H2O).PETCO2 was monitored during mechanically ventilation.Blood samples were obtained from the radial artery immediately after tracheal intubation (T1) and at 1 h of pneumoperitoneum (T2) for blood gas analysis.D(a-ET) CO2 and Qs/Qt were calculated.Results D(a-ET) CO2 and Qs/Qt were significantly lower at T2 in groups B and C than in group A (P ＜ 0.05).Compared with group B,D(a-ET)CO2 was significantly decreased at T2 (P ＜ 0.05),and no significant change was found in Qs/Qt in group C (P ＞ 0.05).Conclusion Decreased FiO2 and PEEP of 5 cm H2O can decrease D(a-ET)CO2 and increase the accuracy of PErCO2 for reflection of PaCO2,which is due to reduced intrapulmonary shunt.
