Objective To explore the effects of bronchoalveolar lavage combined with microbiological rapid on-site evaluation in potential donor lung maintenance.Methods Brain death patients who met the inclusion criteria and were admitted to the Intensive Care Unit(ICU)of Calmette Hospital Affiliated to Kunming Medical University from September 2020 to December 2022 were selected for bronchoalveolar lavage(BAL)and(BAL)and the lavage fluid were collected for M-ROSE to compare the pathogen detection rate and initial diagnosis time.According to the positive results of the microbiological rapid on-site evaluation,patients with the brain death were treated with empirical anti-infective therapy,and the oxygenation index,chest X-ray score,and the infection index(WBC,CRP,PCT)of anti-infective treatment 48 hours were evaluated.Results 1.Comparison of the detection rate of pathogenic microorganisms:The results of M-ROSE were highly consistent with a routine microbiological smear(Kappa = 0.921,P<0.001).2.Comparison of diagnostic time:The initial diagnosis time of M-ROSE was significantly lower than routine microbiological smear time and microbial culture time(P<0.001).3.Comparison of therapeutic effects of anti-infective therapy for 48 hours:There was no significant difference in oxygenation index,white blood cells and hypersensitive C-reactive protein before and after the anti-infective treatment(P>0.05).There were significant differences in procalcitonin and chest X-ray before and after the anti-infective treatment(P<0.05).Conclusion Bronchoalveolar lavage combined with microbiological rapid on-site evaluation has the high timeliness in the diagnosis of potential donor pulmonary infection,which can provide a preliminary basis for the early anti-infective therapy of donor lung maintenance.

Objective:To explore the relationship between platform leadership, perceived overqualification, job crafting and career calling of clinical nurses, and provide references for formulating occupational calling strategies for clinical nurses.Methods:A total of 488 clinical nurses from Qingdao Hiser Hospital Affiliated of Qingdao University(Qingdao Traditional Chinese Medicine Hospital), Shandong University Qilu Hospital, and Qingdao Municipal Hospital were selected as the study subjects by the convenience sampling method from April to May 2023. A general data questionnaire, Platform Leadership Scale, Perceived Overqualification Scale, Job Crafting Scale, and Career Calling Scale were used to conduct a cross-sectional investigation on the research objects, and the relationship and mediating effect between platform leadership, perceived overqualification, job crafting, and career calling were analyzed.Results:Among the 488 clinical nurses, 79 were males and 409 were females, aged 23-51 (30.37 ± 6.40) years old. The scores of platform leadership, perceived overqualification, job crafting and career calling of clinical nurses were (86.12 ± 9.99), (21.79 ± 7.29), (70.61 ± 14.54) and (38.70 ± 7.54) points, respectively. The total effect of platform leadership on work engagement was 0.316. The mediating path of platform leadership to career calling included platform leadership→perceived overqualification→career calling; platform leadership→job crafting→career calling; platform leadership→perceived overqualification→job crafting→career calling. Three mediating effects accounted for 17.99%, 9.50% and 4.56% of the total effect, respectively.Conclusions:There is a chain-mediating effect of perceived overqualification and work remodeling on the relationship between platform leadership and the career calling of clinical nurses. Nursing managers should implement platform leadership to alleviate clinical nurses ′ perceived overqualification, improve job crafting, and then improve the level of clinical nurses ′ career calling.

Objective To investigate the effect of Lumbricus protein on the phenotypic transformation of corporal cavernosum smooth muscle cells(CCSMC)and erectile function in diabetic erectile dysfunction(DMED)rats.Methods Sixty male SD rats with normal erectile function were randomly divided into a blank group,a model group,a Sildelafil group(5 mg·kg-1),and a Lumbricus protein low-,medium-,and high-dose group(45,90,and 180 mg·kg-1),with 10 rats in each group.The diabetic rat model was established by intraperitoneal injection of Streptozotocin(STZ,50 mg·kg-1)combined with high-fat feed feeding;after 8 weeks,the DMED rat model was prepared by neck injection of Apomorphine(APO,100 μg·kg-1).After successful modeling,the rats were administered with a dose of Apomorphine by gavage once a day for 4 weeks.The blood glucose levels and body mass of rats in each group were measured before modeling,on the third day of modeling,and after 4 weeks of drug administration.The intracavernous pressure(ICP)and carotid artery pressure(MAP)were measured by multi-channel physiological recorder,and the ICP/MAP ratio was calculated.The expressions of contractile markers α-smooth muscle actin(α-SMA),smooth muscle myosin heavy chain(SMMHC)and synthetic markers Collagen I and osteopontin(OPN)in corpus cavernosum were detected by immunohistochemistry.The mRNA expression levels of α-SMA,SMMHC and Collagen I in corpus cavernosum were detected by RT-PCR.The protein expression levels of α-SMA,Desmin,Collagen I and OPN in corpus cavernosum were detected by Western Blot.Results Compared with the blank group,the blood glucose levels of the rats in the model group were significantly increased on the third day of modeling and after 4 weeks of administration(P＜0.01),and the body mass was significantly decreased after 4 weeks of administration(P＜0.01).ICP and ICP/MAP ratio were significantly decreased(P＜0.01).The protein expression levels of α-SMA,SMMHC and Desmin in penile corpus cavernosum were significantly decreased(P＜0.01),and the protein expression levels of Collagen I and OPN were significantly increased(P＜0.01).The mRNA expression levels of α-SMA and SMMHC in corpus cavernosum were significantly decreased(P＜0.01),and the mRNA expression level of Collagen I was significantly increased(P＜0.01).Compared with the model group,there was no significant change in blood glucose and body mass of rats in the administration group(P＞0.05).ICP and ICP/MAP ratio were significantly increased(P＜0.01).The expression levels of α-SMA,SMMHC and Desmin in corpus cavernosum were significantly increased(P＜0.01),while the expression levels of Collagen I and OPN were significantly decreased(P＜0.01).The mRNA expression levels of α-SMA and SMMHC in corpus cavernosum were significantly increased(P＜0.01),and the mRNA expression level of Collagen I was significantly decreased(P＜0.01).Conclusion Lumbricus protein can improve the erectile function of DMED rats,and its mechanism may be related to the inhibition of CCSMC from'contractile'to'synthetic(proliferative)'transformation.

"State-target medicine" is a traditional Chinese medicine （TCM） diagnosis and treatment theoretical system proposed by Academician Tong Xiaolin based on the current development of modern medicine. The active stage of gastric ulcer， as a precancerous state of gastric cancer， has a great impact on people's health. Prof. ZHOU Xuewen， a master of TCM， innovatively put forward the theory of "toxicity-heat" etiology for the active stage of gastric ulcer， which plays an important guiding role in clinical diagnosis and treatment. The article took the theoretical system of "state-target medicine" as the framework to explain the rationale， method， formula， and medicine of Prof. ZHOU Xuewen， who applied the Xiaoyong Kuidekang based on the "toxicity-heat" theory to treat the gastric ulcer in the active stage. The Chinese medical name of gastric ulcer， "gastric carbuncle"， was established， and it was believed that gastric ulcer is born due to "toxicity" and is based on "toxicity and heat". In the course of the disease， "toxicity"， "heat"， "deficiency"， and "stasis" coexisted， and its pathogenesis was divided into three phases， namely， toxicity-heat accumulation phase， toxicity-heat affecting the health phase， and weakened body resistance and strengthened toxicity phase. According to the positioning of gastric ulcer as an "internal carbuncle"， Prof. ZHOU Xuewen proposed the treatment of gastric ulcer in the active stage with "carbuncle theory" and introduced the surgical methods of "elimination"， "support"， and "tonifying" into the treatment of gastric ulcer in the active stage. Prof. ZHOU Xuewen took "clearing heat and removing toxins， eliminating carbuncle and generating muscle" as the basic treatment of the disease. For different stages of the disease， Prof. ZHOU Xuewen emphasized the use of the methods of clearing heat and removing toxins， supporting rot and muscle growth， and strengthening the spleen and harmonizing the stomach and created the representative formula for the treatment of gastric ulcer in the active stage with "carbuncle theory"， namely "Xiaoyong Kuidekang"， which could regulate state and targets.

Objective: To analyze the results of colorectal cancer screening among residents in Baoshan District, Shanghai Municipality from 2013 to 2021, so as to provide the basis for promoting colorectal cancer screening and prevention. Methods: Permanent residents aged 50 to 74 years in Baoshan District from 2013 to 2021 were selected as the screening population. The initial screening was conducted using a risk assessment form and fecal occult blood test. Positive results on either the risk assessment form or fecal occult blood test were considered positive for the initial screening. Participants with positive initial screening results were invited to undergo colonoscopy. The positive rate of the initial screening, colonoscopy compliance rate, and colonoscopy results were analyzed. Results: A total of 264 907 individuals underwent the initial colorectal cancer screening in Baoshan District from 2013 to 2021, with 65 333 individuals (24.66%) testing positive. Among them, the positive rate of the risk assessment form was 12.16%, and the positive rate of fecal occult blood test was 14.64%. A total of 14 473 individuals completed colonoscopy, with a compliance rate of 22.15%. A total of 1 284 precancerous lesions were detected, with a detection rate of 8.87%, and 386 cases of colorectal cancer were identified, with a detection rate of 2.67%. The positive rate of the initial screening, colonoscopy compliance rate, precancerous lesion detection rate, and colorectal cancer detection rate were higher in males than in females (25.55% vs. 24.06%, 23.12% vs. 21.45%, 11.60% vs. 6.74%, 3.62% vs. 1.93%, all P<0.05). With increasing age, the positive rate of the initial screening increased, the colonoscopy compliance rate decreased, the precancerous lesion detection rate and colorectal cancer detection rate increased (all P<0.05). From 2013 to 2021, the positive rate of the initial screening among residents showed a downward trend, while the colonoscopy compliance rate showed an upward trend (both P<0.05). Conclusions The detection rate of precancerous lesions in colorectal cancer was 8.87%, and the detection rate of colorectal cancer was 2.67% in Baoshan District from 2013 to 2021. Male and older individuals were the key populations for screening, and the colonoscopy compliance among residents needs to be improved.
