AIMTo research the effect of intermittent hypoxia during sleep on hypothalamus-pituitary-adrenal (HPA) axis and growth hormone (GH) level.

METHODSRats were respectively exposed to intermittent hypoxia, room air and continuous hypoxia, after 1 day, 3 days, 7 days and 30 days, mRNA levels of corticotropin-releasing hormone (CRH) and growth hormone releasing hormone (GHRH) in hypothalamus of rats were detected using RT-PCR, and the levels of CRH, GHRH, corticotropin(ACTH), cortex ketone, and growth hormone in plasma were measured.

RESULTSAfter 30 days, the CRH mRNA levels in rats hypothalamus which exposed to intermittent hypoxia were increased significantly than those exposed to continuous hypoxia as well as normal control but GHRH decreased, there was no difference between continuous hypoxia and normal control. After 1 day, 3 days, and 7 days, there was no difference between continuous hypoxia and intermittent hypoxia. After 30 days, the plasmic level of CRH,ACTH and cortex ketone increased, GHRH decreased and GH had no obvious change.

CONCLUSIONThe rats' HPA axis level increases and GHRH restrained with chronic intermittent hypoxia during sleep, feedback regulation disorders.

Objective The impact of late incomplete stent apposition(ISA)post sirolimus eluting stent(SES)implantation in patients with acute coronary syndrome(ACS)on long-term clinical outcomes remainB controversial.The alm of the present study was to eva]uate the association between late ISA and clinical outcomes in patients with ACS compared with that with stable angina(SA).Methods From February 2005 to March 2007,54 ACS patients and 83 SA patients were enrolled in this study,late ISA was determined by meallS of threc-dimensional volumetric intravaaculair ultrasound(IVUS)analyses one year after SES implantation and clinical outcomes one year post IVUS were obtained in these patients.Results In 219 treated lesions of the 137 patients,late ISA wag documented in 25 lesions in 16 patients(20 ISA in 12 ACS patients vs.5 ISA in 4 SA patients,P＜0.001).Thoush lunlen area in reference and stented segment,neointimal hyperplasia(NIH)area and percentage of NIH in stented segment,and external elastic membrane(EEM)area in reference segment were similar between two groups,EEM area in stented segment [(15.34±5.44)mm2vs.(13.83±4.51)mm2,P=0.026],stented/reference segment EEM area ratio (1.13±0.22 vs.1.02±0.18,P＜0.001),plaque and media area[(8.43±3.93)mm2vs.(7.01±2.93)mm2,P=0.002]was significantly lager in ACS group than that in SA group.Multivariable logistic analysis showed that ACS(OR 6.477 with 95%CI from 2.297 to 18.263,P＜0.001)and stent length≥23 mm(OR 3.680 with 95% CI from 1.181 to 11.469,P=0.025)were main independent factors of occurrence of late ISA.Incidence of main adverse cardiac events(MACE)one year post IVUS Wag similar between the two groups.Conclusion Compared with patients with SA,ACS patients had larger stented segment EEM area,plaque and media areaas well as increased incidence of ISA.However,the incidence of MACE was similar in ACS and SA patients one year after IVUS.

BACKGROUNDLate incomplete stent apposition (ISA) may occur after drug-eluting stent implantation, affecting long-term clinical outcomes. This study aimed to evaluate the impact of clinical presentations of coronary artery disease on late ISA after percutaneous coronary intervention (PCI) with sirolimus-eluting stents (SES) by means of three-dimensional volumetric intravascular ultrasound (IVUS) analyses.

METHODSOne hundred and thirty-seven patients with coronary artery disease received SES implantation during PCI and had repeat angiography with IVUS examination. All patients were followed up one year after the procedure.

RESULTSIn overall 219 treated lesions (137 patients), late ISA was identified in 25 lesions (16 patients). Clinical diagnosis of acute coronary syndrome (ACS) and use of long stents were more common in patients with than in those without late ISA. Patients with late ISA had greater external elastic membrane (EEM) area in stented segment ((15.34 +/- 5.44) vs (13.83 +/- 4.51) mm(2), P = 0.026), stented-to-reference segment EEM area ratio (1.13 +/- 0.22 vs 1.02 +/- 0.18, P < 0.001), and plaque and media area ((8.43 +/- 3.93) vs (7.01 +/- 2.93) mm(2), P = 0.002) than in those without late ISA. Multivariate Logistic regression analysis showed that clinical diagnosis of ACS and use of long stents were independent risk factors for late ISA (OR 6.477, 95% CI 2.297 - 18.263, P < 0.001; OR 3.680, 95% CI 1.181 - 11.469, P = 0.025; respectively). During one-year follow-up after IVUS examination, the rate of very late stent thrombosis tended to be higher in patients with than in those without late ISA (18.7% vs 3.3%, P = 0.051).

CONCLUSIONSThe occurrence of late ISA after SES implantation may be related to clinical status, use of long stents, and marked positive vessel remodeling. Late ISA tended to increase the rate of very late stent thrombosis during follow-up, highlighting the importance of long-term dual antiplatelet therapy for these patients.

Objective To understand the current status of health literacy among Shanghai residents, and to provide information for developing health policy and health education intervention strategies. Methods During 2008-2015, residents of 15-69 years old in Shanghai were investigated, with multi-stage stratified random sampling method. Results Annual increase of health literacy among Shanghai residents of 15-69 years old was witnessed, i.e.21.94%in 2015, an increase of 14.97%com-pared with that in 2008.Among three aspects of health literacy, the level of basic health concept and knowledge, and the level of health related skills were higher than the level of health lifestyle and behaviors.Among six types of health issues, except for infectious disease prevention and health informa-tion, the health literacy level of other four health issues were improved significantly.During the past eight years, the health literacy level of all types of people improved.However, the health literacy level among residents in rural area or with low education level was lower than other groups, and was increasing with slower pace. Conclusoin The intervention of health literacy gains obvious benefits , however,intensive intervention is required for residents with lower health literacy .

Objectives: To investigate the clinical application effect of a quantitative method of atlantoaxial reduction angle in basilar invagination. Methods: A retrospective analysis of clinical and radiographic data was conducted of 38 patients with complicated atlantoaxial dislocation and basilar invagination admitted to the Department of Neurosurgery, First Affiliated Hospital of Chongqing Medical University from May 2020 to May 2022. There were 5 males and 33 females, aged (53.5±9.9) years (range: 38 to 80 years). All patients underwent C_1-2 interarticular fusion cage implantation+occipital-cervical fixation by pressing rob with the cantilever technique. The atlantoaxial reduction model of previous studies by our team was used to calculate the reduction angles before surgery. Then titanium rods of prebending angle were prepared according to the calculation before the operation. After that quantitative reduction of angle was performed during the operation. The paired t-test was used to compare the difference between the theoretical and actual reset value. Results: The theoretical reduction angle of all patients was (10.62±1.78)° (range: 6.40° to 13.20°), the actual reduction angle was (10.53±1.63)° (range: 6.70° to 13.30°) and there was no statistical difference between them (t=1.688, P=0.100). The theoretical posterior occipitocervical angle after the operation of all patients was (117.37±5.88)° (range: 107.00° to 133.00°), the actual posterior occipitocervical angle after the operation was (118.25±6.77)° (range: 105.40° to 135.80°) and there was no statistical difference between them (t=-0.737, P=0.466). The postoperative follow-up time of the patients was more than 6 months and the symptoms of all patients were relieved. All patients had satisfactory fusion between small joints without incision infection, internal fixation fracture, displacement, atlantoaxial redislocation, and other long-term complications. Conclusion: The quantitative method of atlantoaxial reduction angle in basilar invagination can calculate the theoretical reduction angle of the clivus axis angle and guide the preparation of the pre-bending titanium rod before surgery, so as to realize the quantification of the atlantoaxial reduction angle.
