Objective To discuss the clinical value and nursing of the three-endoscope in the treatment of eholedoeholithiasis. Methods 45 eases of choledocholithiasis patients who were treated with LCDE (three-endoscope) were named as the research group.56 patients who received traditional open ab-dominal surgery were set as the control group. The average hospitalization time and satisfaction degree with nursing were compared, t test and χ2 test were adopted. Results The average hospitalization time was shorter and satisfaction degree with nursing was higher in the research group than those in the control group. Conclusions The treatment of choledochohthiasis with three-endoscope is safe and feasible, es-pecially when combined with antibiotics lavage and stone dissolution through naso-biliary duct.The opera-tion can widen the surgical indication,reduce the risk of surgery with little damage,clear stones completely, reduce postoperative complicatioas,make patients recover faster, shorten the hospital stay and achieve the same or better treatment results when compared to the traditional open abdominal surgery.

ObjectiveTo investigate the treatment effects of comprehensive nursing intervention on patients with chronic obstructive pulmonary disease(COPD) treated by non-invasive mechanical ventilation with BiPAP mode.Methods96 patients with diagnosed COPD and using non-invasive mechanical ven- tilation with BiPAP mode were randomly divided into the control group(46 cases) which was treated with routine measures and the comprehensive nursing intervention group (50 cases) which adopted comprehen- sive nursing intervention according to experimental design. The frightening degree, incidence rate of com- plications and clinical treatment effect by ventilator were compared between the two groups.ResultsPa- tients compliance with treatment and clinical treatment effect by ventilator in the comprehensive nursing in- tervention group was better than that of the control group. The frightening degree and incidence rate ofcomplications were lower than those of the control group (P < 0.01 ).ConclusionsComprehensive nurs-ing intervention with non-invasive mechanical ventilation with BiPAP mode can improve the treatmentcompliance of COPD patients,reduce complications followed by non-invasive mechanical ventilation andreach the prospective treatment effect.

Objective:To evaluate the knowledge, attitudes and practices ( KAP) on National Essential Medi-cine System among pharmacists from secondary public hospitals in Shaanxi province. Methods: The quantitative re-search of KAP questionnaire is used, and the content of questionnaire includes personal information, knowledge, atti-tudes and practices. Results: A total of 520 copies of questionnaires were distributed and 82. 3% were effective. Respondents’ overall knowledge and attitudes are at the middle level;the main way to obtain knowledge is via training and meeting;respondents’ education level and frequency of participating in training have a significant impact on their level of knowledge;the degree of attention paid by hospitals has yet to be strengthened; and respondents are mostly concerned about the supply and distribution of essential drugs. Conclusion: In order to improve the awareness and recognition levels of pharmacists on the implementation of National Essential Medicine System in secondary public hospitals, the government should take the relevant measures, including introducing the high educated persons into secondary public hospitals, organizing related training programs and standardizing the daily monitoring of essential drugs in secondary public hospitals, etc.

Objective:To compare the efficacy of conventional Western medicine alone and acupuncture combined with acupoint application in treating intestinal dysfunction secondary to mechanical ventilation in elderly patients with emergency sepsis.Methods:A retrospective analysis was performed on 111 elderly patients with mechanical ventilation for sepsis admitted to the emergency department of Dongzhimen Hospital of Beijing University of Chinese Medicine from January 2019 to June 2021. They were divided into two groups according to the time of admission: Western medicine treatment group alone (patients from January 2019 to December 2019, n=47) and acupuncture combined with acupoint application group (patients from January 2020 to June 2021, n=64). Acupuncture combined with acupoint application group was treated with acupuncture combined with acupoint application on the basis of conventional Western medicine. The intestinal dysfunction score, abdominal circumference and mortality after 4 weeks were compared between the two groups. Results:The abdominal circumference and intestinal dysfunction score in acupuncture combined with acupoint application group were significantly lower than those before treatment [(100.56±9.34)cm vs (106.25±9.74)cm; (0.92±0.72)point vs (2.31±0.69)point, all P< 0.05], while there was no significant difference in the above indexes before and after treatment in the Western medicine treatment group (all P>0.05). The abdominal circumference, intestinal dysfunction score and mortality after 4 weeks in the acupuncture combined with acupoint application group were significantly lower than those in the Western medicine treatment group [(100.56±9.34)cm vs (108.09±10.52)cm; (0.92±0.72)point vs (2.43±0.62)point; (29.7%, 19/64) vs (48.9%, 23/47), all P<0.05]. Conclusions:The curative effect of acupuncture combined with acupoint application in the treatment of intestinal dysfunction secondary to mechanical ventilation in elderly patients with sepsis in emergency is better than that of routine treatment of Western medicine alone. The gastrointestinal function and prognosis of patients have been significantly improved, which is worthy of clinical promotion.

Objective:Animal models of sepsis are mainly established by cecal ligation and puncture which causes mixed bacterial infections in the abdominal cavity. However in internal clinic, sepsis is more common to be caused by respiratory bacterial infections. Therefore, it is necessary to establish animal models of sepsis caused by lung Infection.Methods:According to the concentration of Staphylococcus aureus (S. aureus) suspension and Pseudomonas aeruginosa (P. aeruginosa) suspension, Sprague Dawley (SD) rats were equally divided into 10 groups, including S-Cont group, S-0.75 group, S-1.5 group, S-3 group, S-6 group and P-Cont group, P-1 group, P-2 group, P-4 group, P-8 group. Rats in the control group were treated with normal saline nasal drip. Rats in each experimental group were infected by nasal dripping bacterial suspension with 0.75×10 8 CFU/ml, 1.5×10 8 CFU/ml, 3×10 8 CFU/ml, 6×10 8 CFU/ml of S. aureus suspension or 1×10 8 CFU/ml, 2×10 8 CFU/ml, 4×10 8 CFU/ml, 8×10 8CFU/ml P. aeruginosa suspension. Our study detected the body temperature (T), blood pressure (BP), heart rate (HR) of rats in each group before and after infection, as well as blood lactic acid (Lac) and procalcitonin (PCT) level after infection. The lung infections of rats in each group were observed by hematoxylin-eosin (HE) staining. Results:The blood pressure(BP) of S-1.5 group, S-3 group, S-6 group and P-8 group was lower than before infection (all P<0.05). The Lac and PCT of each S. aureus experimental group were higher than that of the S-Cont group (all P<0.01); and they showed an increasing trend with the increase of the bacterial suspension concentration ( P<0.05), except for the S-3 and S-6 group ( P>0.05). The Lac and PCT of each P. aeruginosa experimental group were higher than that of the P-Cont group (all P<0.01); and they showed an increasing trend with the increase of the bacterial suspension concentration (all P<0.05), except for the Lac in the P-4 group and P-8 group ( P>0.05). HE staining showed that different degrees of inflammatory infiltration can be seen in the lungs of the experimental rats in each group. Conclusions:Infection of rats by nasal dripping with 3×10 8 CFU/ml of S. aureus suspension or 4×10 8 CFU/ml of P. aeruginosa suspension could establish relatively stable rat sepsis model induced by lung bacterial infection, of which the former could also establish a relatively stable septic shock model.

Objective:The changes of serum inflammatory factors in patients with chronic obstructive pulmonary disease (COPD) with different traditional Chinese medicine (TCM) syndrome types were compared, and the characteristics and significance of inflammatory factors in COPD were discussed from the perspective of traditional Chinese and western medicine.Methods:A total of 100 patients with COPD who met the inclusion criteria and were admitted to Dongzhimen Hospital of Beijing University of Chinese Medicine from September 2021 to September 2022 were selected and divided into phlegm turbation obstructing lung group ( n=50) and lung and kidney qi deficiency group ( n=50) according to TCM syndrome types. Twenty healthy subjects in the same period were selected as control group. Serum levels of monocyte chemoattractant protein-1 (MCP-1), macrophage inflammatory protein-1α (MIP-1α), interleukin-6 (IL-6), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and other inflammatory factors were compared in each group. Results:The MCP-1, IL-6, ESR, CRP, white blood cell count (WBC) and procalcitonin (PCT) of COPD patients in phlegm turbation obstructing lung group were significantly higher than those in lung and kidney qi deficiency group (all P<0.05). The WBC, MCP-1, MIP-1α, IL-6, ESR and CRP of COPD patients in the lung and kidney qi deficiency group were significantly higher than those in the control group (all P<0.05). In the phlegm turbation obstructing lung group, the MIP-1α, MCP-1, IL-6, ESR, CRP, WBC, and PCT were significantly higher than those in the control group (all P<0.05). Conclusions:Patients with COPD have inflammatory reactions, and the inflammatory reactions of patients with phlegm turbation obstructing lung syndrome are more obvious than those with lung and kidney qi deficiency syndrome. The inflammatory factors MCP-1, MIP-1α, IL-6, ESR, CRP, WBC, PCT and other indicators could be used to judge the degree of COPD inflammation, which had certain clinical guiding significance for different syndrome types of COPD patients.

Objective To study the protective effect and mechanism of adenosine A2a receptor(A2aR)activation in the pathogenesis of systemic sclerosis associated interstitial lung disease(SSc-ILD).Methods A total of 24 healthy female Balb/c mice were randomly divided into three groups:wild normal control(WN)group,wild model(WM)group,WM with CGS21680(WMC)group.Two weeks after the end of injections,the lung samples and serum of mice were collected.A part of lung tissues were obtained for hematoxylin eosinstaining,Masson staining and determination of hydroxyprolineto observe the degree of inflammation and fibrosis.Enzyme linked immunosorbent assay(ELISA)was used to detect advanced oxidative protein products in mouse serum and lung tissue,reduced glutathione in lung tissue,and oxidative stress levels in serum and lung tissue.Results①Underhematoxylin eosinstaining and Masson staining,the lungs of mice in WM group showed inflammation infiltration and fibrosis,while mice in WMC group showed a reduction compared to mice in WM group;②The content of hydroxyproline in lung tissue,serum and late stage oxidative protein products in lung tissue of WM group mice increased compared to WN group mice(P<0.01),while the content of WMC group mice decreased compared to WM group mice(P<0.01);③The reduced glutathione content in lung tissue of WM group mice was lower than that of WN group mice(P<0.01),while WMC group mice were higher than WM group mice(P<0.05).Conclusion The activation of A2aR ameliorated the degree of inflammation and fibrosis in SSc-ILD,possibly through the antioxidant mechanism.
