Objective:To explore the clinical application effects of early pulmonary rehabilitation training based on bundle airway management in patients with tracheostomy and non-mechanical ventilation.Methods:Used convenience sampling, adult patients who underwent tracheostomy and non-mechanical ventilation admitted to Fenyang Hospital of Shanxi Province from January 2022 to May 2023 were enrolled. Patients were divided into control group and observation group based on their admission dates. The control group implemented bundle airway management based on the Airway care for patients with tracheostomy and non- mechanical ventilation. The observation group received additional pulmonary rehabilitation training implemented by a specialized respiratory rehabilitation team. The primary outcomes included hospital stay duration, improvement rate of muscle strength, diaphragmatic mobility, and successful extubation rate. Secondary outcomes included the incidence of pulmonary infection, improvement rate of self-care ability, and the duration of tracheal tube placement in extubated patients. Results:A total of 41 patients were included in the control group and 39 patients in the observation group. There were no significantly differences in gender, age, first diagnosis of disease, and activities of daily living (ADL) score at admission between the two groups, indicating balanced baseline data and comparability. Compared with the control group, the observation group had a significantly shorter hospital stay (days: 38.33±17.58 vs. 51.34±27.06), a higher improvement rate of muscle strength (76.92% vs. 39.02%), greater diaphragmatic mobility (cm: 1.86±0.64 vs. 1.44±0.57), and a higher success rate of tracheostomy tube extubation (38.46% vs. 17.07%), the duration of tracheal tube placement in successfully extubated patients was significantly reduced (days: 33.26±17.87 vs. 50.60±21.98), with all differences being statistically significant (all P < 0.05). Although the improvement rate of ADL score (56.41% vs. 36.59%) and the incidence of pulmonary infection (5.13% vs. 7.32%) in the observation group were better than those in the control group, but there were no differences (both P > 0.05). Conclusion:The addition of pulmonary rehabilitation training in bundle airway management can enhance exercise tolerance, improve respiratory function, promote sputum clearance, increase successful extubation rates, shorten hospital stays, and facilitate early recovery in patients with tracheostomy and non-mechanical ventilation.

Currently, there is still no effective curative treatment for the development of late-stage liver fibrosis. Here, we have illustrated that TB001, a dual glucagon-like peptide-1 receptor/glucagon receptor (GLP-1R/GCGR) agonist with higher affinity towards GCGR, could retard the progression of liver fibrosis in various rodent models, with remarkable potency, selectivity, extended half-life and low toxicity. Four types of liver fibrosis animal models which were induced by CCl₄, α-naphthyl-isothiocyanate (ANIT), bile duct ligation (BDL) and Schistosoma japonicum were used in our study. We found that TB001 treatment dose-dependently significantly attenuated liver injury and collagen accumulation in these animal models. In addition to decreased levels of extracellular matrix (ECM) accumulation during hepatic injury, activation of hepatic stellate cells was also inhibited via suppression of TGF-β expression as well as downstream Smad signaling pathways particularly in CCl₄-and S. japonicum-induced liver fibrosis. Moreover, TB001 attenuated liver fibrosis through blocking downstream activation of pro-inflammatory nuclear factor kappa B/NF-kappa-B inhibitor alpha (NFκB/IKBα) pathways as well as c-Jun N-terminal kinase (JNK)-dependent induction of hepatocyte apoptosis. Furthermore, GLP-1R and/or GCGR knock-down results represented GCGR played an important role in ameliorating CCl₄-induced hepatic fibrosis. Therefore, TB001 can be used as a promising therapeutic candidate for the treatment of multiple causes of hepatic fibrosis demonstrated by our extensive pre-clinical evaluation of TB001.

Objective:To observe the effect of tracheotomy high-flow oxygen therapy (THFO) on the clinical efficacy of non-mechanically ventilated patients undergoing a tracheotomy.Methods:Sixty adult patients with tracheotomy and non-mechanical ventilation who were diagnosed and treated from January 2019 to December 2020 in Fenyang Hospital of Shanxi Province were enrolled. According to the random number table, the patients were divided into Venturi oxygen therapy group and THFO group, 30 cases in each group. The THFO group was given oxygen therapy with THFO; the Venturi group (without mask) was given Venturi connected the MR850 base and the ventilator tube. Observe the changes of two groups at 7 AM within 5 days, including body temperature which was 1 ℃ higher than the baseline, white blood cell count (WBC) which was 2×10 9/L higher than baseline, oxygenation index (PaO 2/FiO 2) < 300 mmHg (1 mmHg = 0.133 kPa), the occurrence of lower respiratory tract infections (based on radiography), and changes in sputum indexing and sputum formation. Results:Compared with the Venturi oxygen therapy group, the body temperature increased > 1 ℃, WBC increased by 2×10 9/L, PaO 2/FiO 2 < 300 mmHg, and the proportion of lower respiratory tract infection in THFO group decreased significantly [body temperature increased > 1 ℃: 10.0% (3/30) vs. 13.3% (4/30), WBC increased by 2×10 9/L: 10.0% (3/30) vs. 30.0% (9/30), PaO 2/FiO 2 < 300 mmHg: 3.3% (1/30) vs. 10.0% (3/30), the proportion of lower respiratory tract infection: 6.7% (2/30) vs. 13.3% (4/30), all P < 0.05]. The proportion of patients with sputum scab formation and sputum viscosity of Ⅰ degree were significantly increased [sputum scab formation: 16.7% (5/30) vs. 6.7% (2/30), sputum viscosity of Ⅰ degree: 30.0% (9/30) vs. 20.0% (6/30), both P < 0.05]. Conclusion:THFO during non-mechanical ventilation of adult patients with tracheotomy can maintain a higher oxygen partial pressure and ideally control the temperature and humidity of the inhaled gas, promote the discharge of sputum with degreeⅠ andⅡ viscosity, thereby reducing the tracheotomy complications such as lower respiratory tract infections.

Objective:To explore the effect of bundle management strategy in early mobility of patients with mechanical ventilation.Methods:Seventy-two mechanically ventilated patients admitted to the respiratory intensive care unit (RICU) of Fenyang Hospital of Shanxi Province from December 2019 to June 2020 were enrolled. The patients were divided into routine nursing control group (routine control group) and early mobility bundle management group (bundle group), with 36 cases in each group. The routine control group received regular nursing, including monitoring vital signs, raising the head of the bed, turning over and buttoning the back every 2 hours, daily awakening, airway humidification, prevention of digestive tract ulcer, analgesia and sedation management, prevention of deep vein embolism, pipeline management, regular monitoring of blood gas analysis and electrolytes according to the changes of the condition, prevention of aspiration, prevention of bacterial colonization, correct hand hygiene, and so on. The bundle group implemented the cluster early mobility strategy based on routine nursing. Firstly, set up a professional team to execute the standards. The team determined the plan and implemented the 4-level mobility plan, companied with psychological intervention, decided the termination standard and quality control. The incidence of intensive care unit acquired weakness (ICU-AW), ventilator-associated pneumonia (VAP), delirium, the duration of mechanical ventilation and the length of intensive care unit (ICU) stay were evaluated.Results:Compared with the routine control group, the incidences of ICU-AW, VAP, and delirium in the bundle group were significantly lower (the incidence of ICU-AW: 36.11% vs. 69.44%, χ 2 = 8.025, P = 0.005; the incidence of VAP: 8.33% vs. 30.56%, χ 2 = 5.675, P = 0.017; the incidence of delirium: 5.56% vs. 36.11%, χ 2 = 10.180, P = 0.001), the duration of mechanical ventilation was significantly shorter (days: 7.13±1.34 vs. 10.46±1.48, t = -10.145, P < 0.001), and the length of ICU stay was also significantly decreased (days: 9.03±2.43 vs. 13.06±3.63, t = -5.535, P < 0.001). Conclusions:The implementation of bundle management strategy of early mobility can promote the rehabilitation of mechanical ventilated patients, improve the prognosis and the quality of life. The effect is noticeable and it is worth popularizing.

Objective To investigate the effect of oxygen therapy with Venturi combined with MR850 heating humidifier on patients without mechanical ventilation after tracheotomy. Methods Eighty patients (≥ 18 years old) who had undergone tracheotomy and without mechanical ventilation admitted to Fenyang Hospital of Shanxi Province from June 2016 to December 2017 were enrolled, and they were divided into control group and observation group according to random number table method, with 40 patients in each group. The observation group was given Venturi (removed the mask) combined with MR850 device active warm and humid oxygen therapy; the control group was given one-off ordinary flow device and warm and humid exchanger (artificial nose, HME) passive humid oxygen therapy.

Results Among the 80 patients, there were 46 males and 34 females, with an average age of (67.7±12.2) years. Compared with the control group, the incidence of increased body temperature (5.0% vs. 20.0%), the incidence of increased WBC (7.5% vs. 35.0%), the incidence of low PaO2/FiO2(2.5% vs. 7.5%), the incidence of airway mucosal bleeding (5.0 % vs. 15.0%) and the incidence of pulmonary infection (2.5% vs. 10.0%) were significantly decreased in the observation group (all P < 0.01), and the proportion of sputum viscosity Ⅰ degree of patients was significantly increased (57.5% vs. 12.5%, P < 0.01). Conclusion Venturi combined with MR850 device can effectively control airway temperature and humidity, promote sputum dilution and conducive to drainage, reduce pulmonary infection in adults patients without mechanical ventilation after tracheotomy, thereby reducing postoperative complications of tracheotomy.

Objective To observe the differences in functional capacities generated by different simple breathing balloons extruded by different hand types and methods.Methods The lung functional measurement instrument was used to measure the generated functional capacities of two types of simple breathing balloon extruded by different hand methods: using big-, mid- and small-size hands with 5 fingers generally separately open and maximally extended states or with both small-size hands to extrude balloon; the effective generated gas quantity of the above methods were compared.Results ① Comparison between different balloons: the functional capacity generated by black rubber balloon extruded by any hand type was 68 - 132 mL lower than that generated by light blue silicon balloon. ② The comparison between different hand types: the functional capacities generated by any hand at maximally extended state in extruding balloon was 13 - 70 mL higher than that by hand commonly separate state; extrusion by a small size hand was nearly unable to reach 400 mL, while the functional capacity was 520 - 650 mL when the balloon was extruded by a big size hand, and 435 - 635 mL by a mid-size hand; it was necessary to use both small hands when the black rubber balloon was extruded, when the light blue silicon air bag was extruded, the functional capacity could reach 430 - 440 mL with a small size hand. ③ Difference in extruding methods: the functional capacity generated by either big size hand or mid-size hand with 5 fingers maximally extending state to extrude balloon was significantly higher than that with 5 fingers commonly separate state, the functional capacity generated by both small size hands with fingers maximally separating and extending state to extrude balloon was obviously higher than that generated by 5 fingers generally separating and extending state, the functional capacities generated by light blue silicon balloon were obviously higher than those by black rubber balloon, no matter the 5 fingers of big- or mid-size hand being at generally separating or extending state (mL: 623.00±21.11 vs. 522.00±41.85 by big size hand with common 5 fingers separate state, 649.00±26.01 vs. 575.00±58.55 by big sizehand with maximum 5 fingers extending state; 566.00±37.77 vs. 436.00±21.19 by mid-size hand with common 5 fingers separate state, 637.00±30.02 vs. 505.00±37.49 by mid-size hand with maximum 5 fingers extending state); the light blue silicon balloon extruded by small hand with 5 fingers at generally separate state and at maximally extending state could generate functional capacities (mL)432.00±13.02 and 444.00±37.18 respectively, significantly higher than those using the 2 types of hand state extruding a black rubber balloon (the tidal volume < 400 mL), the functional capacities generated by both small hands extruding a light blue silicon balloon was obviously higher than that by using a black rubber balloon (mL: 557.00±54.98 vs. 489.00±40.12, allP < 0.05).Conclusions Different functional capacities will be generated by different hand sizes, different hand extruding methods and types of simple breathing balloon, clinical application should be based on patients' body weights to decide their tidal volumes, and combined with the rescuers' hand sizes and types of simple breathing balloon to choose a proper extruding method for a certain patient, thus sufficient oxygen can be surely provided in time for him/her and rescue successful rate can be elevated.

Objective: To determine the personal dose level of radiation workers in medical institutions at the municipal level and below in a city, and to provide a scientific support for strengthening the radiation protection in the city’s medical institutions. Methods: Information of the successful applicants for the "Radiation Worker Permit" from 174 medical institutions at the municipal level and below was collected from October 1, 2011 to December 31, 2014. The annual effective dose was calculated based on the personal dose monitoring report, and indicators including sex, permit application time, hospital level, type of occupational radiation, length of radiation work, blood test, and micronucleated lymphocyte rate were analyzed. Results: Of the 1 143 radiation worker permit applications submitted by medical institutions the municipal level and below in this city from 2011 to 2014, 1 123 provided at least one personal dose monitoring report. The annual effective dose of the radiation workers was 0-4.76 mSv (mean 0.31±0.40 mSv) , and the collective annual effective dose was 351.96 mSv. The annual effective dose was significantly different between radiation workers with different times of permit application, hospital levels, and types of occupational radiation (P<0.05) . Interventional radiology workers had the highest annual effective dose (0.63 mSv) , and annual effective dose was significantly different between interventional radiology workers with different lengths of radiation work (H=10.812, P<0.05) . Conclusion The personal radiation dose of radiation workers in medical institutions at the municipal level and below in this city is maintained at a relatively low level, suggesting that the occupational environment is relatively safe for these workers. However, more focus should be placed on clinical interventional radiology workers.
