Objective: To evaluate the effect of Triangle hierarchical management among community patients with hypertension, so as to provide insights into the improvements of standardized hypertension management. Methods: Patients with newly diagnosed hypertension from 2 community health service centers in Qiantang District of Hangzhou City by the end of 2020 were randomly assigned to the conventional group and the Triangle group. Patients in the conventional group were given health management services according to the requirements of basic public health service standard for one year, while patients in the Triangle group were given Triangle hierarchical management. The blood pressure, self-management behaviors, treatment compliance, smoking, alcohol consumption and exercise were collected using the self-management behavior scale, treatment compliance scale and self-designed questionnaires, and were compared before and after intervention with analysis of covariance and generalized estimation equations. Results: Totally 200 patients with hypertension were recruited, including 100 patients in the conventional group and 100 patients in the Triangle group. There were no significant differences between the two groups before implementation of interventions in terms of gender, age, educational level or occupation (P>0.05). The reduction in blood pressure, increase in the score of treatment, diet, exercise and living habitat management and the total score of self-management behaviors, increase in the score of adherence to medication regimens, daily living management behaviors, smoking and alcohol consumption preference and the total score of treatment compliance, and increase in the number of patients with normal standard of quitting smoking, quitting alcohol consumption, exercise and blood pressure were significantly higher in the Triangle group than in the conventional group after intervention (P<0.05). Conclusions Triangle hierarchical management may increase the treatment compliance, improve the self-management behavior and facilitate hypertension control among hypertensive patients, which may be popularized for health management among community patients with hypertension.

ObjectiveTo discuss the clinical experience and influence factors of airway complications after lung transplantation for end-stage lung diseases through reviewed 28 lung transplantation cases in our center.MethodsFrom August 2005 to December 2010,28 patients with end-stage lung diseases received lung transplantations consecutively in our center,in which 13 patients were bilateral-lung transplantation(BLT) and 15 patients were single-lung transplantation(SLT).The donor lungs were perfused with LPD solution antegrade and retrograde followed.During operation,the pulmonary artery pressure and flow rate were tested real time through the transesophageal echocardiography and Swans catheter.Postoperative care of patients was in respiratory intensive care unit,and immunosuppressive drugs were adjusted according to blood drug concentration.ResultsThere were no airway complications including anastomotic fistula or stenosis found in all patients.The mortality was 7.2％ in the early postoperative period ( 1-30 days).Cumulative survival rate was 94.1％ ％ at 1 year,76.2％ at 2 years,and 71.4％ at 3 years respectively.Four patients (14.3％) died in the postoperative 90 days.Three patients were reanastomosed pulmonary artery in operation because of stenosis detected by transesophageal echocardiography.After operation,three patients were reoperated,in which two were bleeding and one was pulmonary bulla and pneumothorax.All patients were followed from 1 year to 6.1 years after operation.The quality of life was improved significantly.ConclusionThe well improved technique of lung transplantation is helpful to reduce the operation related complications,decrease the early mortality post operation and play the important role in the effects of quality of life and long term survival rate.The intraoperative transesophageal echocardiography examination could detect the anomalous situation of vascular anastomosis.At the same time the patients should get benefits from the routine and close follow-up.

OBJECTIVE: To investigate the effect of different fraction of inspired oxygen (FiO₂) baseline levels before endotracheal intubation on the time of expiratory oxygen concentration (EtO₂) reaching the standard in emergency patients with the EtO₂ as the monitoring index. METHODS: A retrospective observational study was conducted. The clinical data of patients receiving endotracheal intubation in the emergency department of Peking Union Medical College Hospital from January 1 to November 1 in 2021 were enrolled. In order to avoid interference with the final result due to inadequate ventilation caused by non-standard operation or air leakage, the process of the continuous mechanical ventilation after FiO₂ was adjusted to pure oxygen in patients who had been intubated was selected to simulate the process of mask ventilation under pure oxygen before intubation. Combined with the electronic medical record and the ventilator record, the changes of the time required to reach 0.90 of EtO₂ (that was, the time required to reach the standard of EtO₂) and the respiratory cycle required to reach the standard after adjusting FiO₂ to pure oxygen under different baseline levels of FiO₂ were analyzed. RESULTS: 113 EtO₂ assay records were collected from 42 patients. Among them, 2 patients had only one EtO₂ record due to the FiO₂ baseline level of 0.80, while the rest had two or more records of EtO₂ reaching time and respiratory cycle corresponding to different FiO₂ baseline level. Among the 42 patients, most of them were male (59.5%), elderly [median age was 62 (40, 70) years old] patients with respiratory diseases (40.5%). There were significant differences in lung function among different patients, but the majority of patients with normal function [oxygenation index (PaO₂/FiO₂) > 300 mmHg (1 mmHg ≈ 0.133 kPa), 38.0%]. In the setting of ventilator parameters, combined with the slightly lower arterial partial pressure of carbon dioxide of patients [33 (28, 37) mmHg], mild hyperventilation phenomenon was considered to be widespread. With the increased in FiO₂ baseline level, the time of EtO₂ reaching standard and the number of respiratory cycles showed a gradually decreasing trend. When the FiO₂ baseline level was 0.35, the time of EtO₂ reaching the standard was the longest [79 (52, 87) s], and the corresponding median respiratory cycle was 22 (16, 26) cycles. When the FiO₂ baseline level was increased from 0.35 to 0.80, the median time of EtO₂ reaching the standard was shortened from 79 (52, 78) s to 30 (21, 44) s, and the median respiratory cycle was also reduced from 22 (16, 26) cycles to 10 (8, 13) cycles, with statistically significant differences (both P < 0.05). CONCLUSIONS The higher the FiO₂ baseline level of the mask ventilation in front of the endotracheal intubation in emergency patients, the shorter the time for EtO₂ reaching the standard, and the shorter the mask ventilation time.

Objective This study reconstructed 4D-CBCT for fully automatic compensated sliding motion by incorporating the bilateral filtering into the Deformable Vector Field (DVF). Methods First, a motion compensated simultaneous algebraic reconstruction technique (Modified Simultaneous Algebra Reconstruction Technique, mSART) was used to generate a high quality reference phase by using all phase projection stogether with the initial 4D-DVFs, which were generated via Demons registration between 0% phase and each other phaseimage. The 4D-DVF was optimized by matching the forward projection of the deformed 0% phase with the measured projection of the target phase. The loss function’s DVF smoothing constrain term contained bilateral filtering kernel that contained: 1) an spatial domain Guassian kernel; 2) animage intensity domain Guassian kernel; and 3) a DVF domain Guassian kernel. By choosing suitable kernel variances, the sliding motion can be extracted. A non-linear conjugate gradient optimizer wasused. We validated the algorithm on a Non-Uniform Rotational B- spline based Cardiac-Torso (NCAT) phantom. Quantification was evaluated by: 1) the Root-Mean-Square-Error (RMSE) together with the Maximum-Error (MaxE); 2) the Dice coefficient of the extracted lung contour from the final reconstructed images and 3) the relative reconstruction error (RE) to evaluate the algorithm's performance. Results The motion trajectory's RMSE/MaxEare 0.796/1.02 mm for bilateral filtering reconstruction; and 2.704/4.08 mm for original reconstruction. Image content such a stherib position, the hearted gedefinition, the fibrous structures all had been better corrected with bilateral filtering. Conclusion We developed a bilateral filtering based fully automatic sliding motion compensated 4D-CBCT scheme. Digital phantom study confirmed the improved motion estimation and image reconstruction ability. It can be used as a 4D-CBCT image guidance tool for lung SBRTtreatment.
