Acute pancreatitis (AP) is a life-threatening gastrointestinal disorder for which no effective pharmacological treatments are currently available. One of the pharmacological targets that merits further research is the neurokinin 1 receptor (NK1R), which is found on pancreatic acinar cells and responds to the neuropeptide substance P (SP) that participates in AP. Although a few studies have stated the involvement of SP/NK1R in neurogenic inflammation in AP development, the regulatory mechanism remains unclear. In this study, we found that following activation of NK1R by SP, β-arrestin1, a scaffold protein of NK1R, down-regulated transcription of Adss, Adsl, and Ampd in the purine nucleotide cycle, thereby inhibiting mitochondrial function through fumarate depletion. Interestingly, we identified magnolol as a new and natural NK1R inhibitor with a non-nitrogenous biphenyl core structure. It exhibited a beneficial effect on AP by restoring purine nucleotide cycle metabolic enzymes and fumarate levels. Our study not only provides new therapeutic strategies, leading compounds, and drug translation possibilities for AP, but also provides important clues for the study of downstream mechanisms driven by SP in other diseases.

Objective:To assess respondents' understanding of the items in the Neck Dissection Impairment Index (NDII) through cognitive interviews and to revise the items accordingly.Methods:Totally 30 postoperative neck dissection patients returning for follow-up at Department of Otolaryngology-Head and Neck Surgery, Beijing Tongren Hospital, Capital Medical University from November 2023 to February 2024, were selected by purposive sampling for two rounds of cognitive interviews. Based on the interview results, the Chinese version of the NDII was revised.Results:The Chinese version of the NDII included ten items. The first round of interviews identified issues such as "incomplete expression, abstract language, and written form, " leading to revisions of five items. The second round of interviews showed that all respondents understood the revised items, and no new suggestions for modification were made.Conclusions:Cognitive interviews can improve respondents' comprehension of the Chinese version of the NDII, identify cognitive biases caused by cultural differences and improper linguistic expressions during the translation process, and enhance the understanding and acceptance of the scale's content among the target population.

Objective To explore the epidemiological characteristics and cost structure of hospitalized patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD)in a tertiary comprehensive hospital in Xi'an from 2014 to 2023.Methods The first page information of AECOPD inpatients in a hospital from January 2014 to December 2023 was col-lected(n=6 748),and the distribution of their demographic characteristics and clinical characteristics as well as the composition of hospitalization expenses were retrospectively analyzed,and the structural change degree was used to analyze the structural change of hospitalization expenses in different years.Results AECOPD patients diagnosed and hospitalized accounted for 4.81 ‰ of all hospitalized patients in this institution from 2014-2023,the proportion of AECOPD inpatients showed a continuous downward trend during 10 years(x2=1 083.351,P＜0.001);The distribution of gender,occupation,medical payment meth-ods,and sources of AECOPD inpatients in different years showed statistical differences(P＜0.05);There is a statistical differ-ence in the seasonal distribution of AECOPD inpatients in different years(x2=157.328,P＜0.001);There is a statistical difference in the average length of hospital stay among AECOPD inpatients in different years(x2=83.463,P＜0.001);There were statistically significant differences in the proportion of hospitalizations,admission conditions,comorbidities or complications,history of drug allergies,and readmission plans among AECOPD patients in different years(P＜0.05);There is a statistical difference in the outcomes of hospitalized AECOPD patients in different years(x2=153.367,P＜0.001);The average hospital-ization cost of AECOPD patients gradually increased from 2014-2016,and gradually decreased from 2016-2023(P＜0.01);The hospitalization expenses of AECOPD patients in different years are mainly based on drug expenses and diagnostic expenses;The overall degree of structural change(DSV)of average hospitalization expenses for AECOPD patients from 2014-2022 was 41.62％,with the highest DSV of hospitalization expenses in 2012-2013(22.69％)and the lowest DSV in 2017-2018(4.23％);The proportion of drug expenses in the average hospitalization cost of AECOPD patients continued to decline,while diagnostic expenses,hygiene material expenses,medical service expenses,and nursing expenses showed an overall increasing trend from 2014-2023.Conclusion The proportion and mortality rate of hospitalized AECOPD patients have shown an overall downward trend in the past 10 years;The proportion of hospitalized AECOPD patients in the age group of 70-79 is the highest,mainly distributed in winter;The overall average hospitalization cost over the past 10 years has shown a downward trend,with drug and diagnostic expenses as the main components.Drug expenses have been decreasing year by year,while diagnostic expen-ses have been increasing year by year.This indicates that medical policy reform plays a significant role in optimizing the hospitali-zation cost structure and controlling unreasonable cost growth.

Objective To analyze the clinical effect of ultrasound-guided quadratus lumborum block(QLB)and erector spinae plane block(ESPB)in elderly patients with laparoscopic colorectal cancer surgery.Methods A total of 75 elderly patients who underwent elective laparoscopic radical resection of colorectal cancer in wenzhou central hospital,from August 2021 to March 2022 were selected and divided into quadratus lumborum group(group Q,n=25),erector spinae muscle group(group E,n=25)and group C(n=25).Group Q received QLB combined with general anesthesia,group E received ESPB combined with general anesthesia,the group C was given tracheal intubation with total intravenous general anesthesia.The perioperative anesthesia and analgesic dosage,postoperative recovery quality,resting and cough visual analogue scale(VAS)scores were compared among the groups.Results In contrast to the group C,the number of effective PCIA compressions,the dose of sufentanil,and the analgesic rescue rate were significantly decreased in groups Q and E(P<0.05);In contrast to the the group C,the spontaneous breathing,eye opening and tracheal extubation time of patients in group Q and group E were apparently shortened(P<0.05),and patients in group Q and group E recovered indoor nausea and vomiting,lethargy,restlessness and respiratory depression The number of cases was apparently reduced(P<0.05);at each time point from 2 to 48 hours after operation,compared with the group C,the VAS scores at rest and cough in groups Q and E were apparently decreased(P<0.05).However,there was no significant difference in the above indicators between the group Q and the group E(all P>0.05).Conclusion Ultrasound-guided QLB and ESPB for laparoscopic colorectal cancer surgery can both improve the quality of recovery and achieve satisfactory analgesia in elderly patients.

NUF2 is responsible for the attachment of kinetochore-microtubules and proper chromosome segregation during mitosis. NUF2 is highly expressed in hepatocellular carcinoma, pancreatic cancer, esophageal cancer, non-small cell lung cancer, breast cancer and other tumor tissues and cells, and can be used as prognostic markers. Further clarifying the relationship between NUF2 and tumor prognosis can provide help for the application of NUF2 in prognostic assessment of cancers.

Objective:To investigate the expression of promyelocytic leukemia zinc finger (PLZF) in human peripheral blood with asthma and its clinical significance.Methods:Forty patients with stable asthma from May 2021 to October 2021 in the Department of Respiratory Medicine of the Shanghai Fifth People's Hospital were enrolled, and forty healthy controls were recruited in the study. The levels of cytokines in serum were measured by enzyme-linked immunosorbent assay (ELISA). Quantitative real-time PCR (qPCR) was used to detect the expression of PLZF mRNA in plasma. The level and distribution of PLZF+ cells in PBMCs were detected by flow cytometry after isolating peripheral blood mononuclear cells (PBMCs). Independent sample t test, Mann-Whitney U test, χ 2 test, ROC curve and Logistic regression were used to analyze the results with SPSS 26.0 and Graphpad Prism 7.0. A P<0.05 was considered statistically significant. Results:The levels of cytokines IFN-γ, IL-2, IL-4, TNF-α and IL-17 in human peripheral blood from the asthma group were obviously higher than those in the control group ( P<0.05), whereas there was no significant difference in the level of cytokine IL-10 between the two groups. The level of PLZF mRNA in PBMCs from the asthma group was significantly up-regulated compared to that in the control group [(3.40%±2.52%) vs. (1.23%±0.78%), P<0.05]. CD8+PLZF+ and Vβ11+PLZF+T cells in the asthma group were significantly outnumbered than those in the control group ( P<0.05). Logistic regression and ROC curve analysis showed that PLZF expression in PBMC was a risk factor for the development of asthma ( OR =3.67, AUC=0.87, P<0.05). Conclusions:The high expression of PLZF in peripheral blood may play an important role in the development of asthma, which needs to be further confirmed by large sample studies.

Objective:To analyze the clinical features, treatment and prognosis of asymptomatic patients with retinoblastoma.Methods:A retrospective series of case study. Eight asymptomatic patients (11 eyes) with the diagnosis of retinoblastoma by screening enrolled in Department of Ophthalmology of The Eye-ENT Hospital of Fudan University from January 2006 to March 2019 were included. There were 6 males and 3 females ranging from 2 days to 20 months, with a median age of 6 months. Five patients were unilateral retinoblastoma while 3 patients were bilateral. Based on the International Classification of Intraocular Retinoblastoma, 4 eyes were stage A, 3 eyes were stage B and 4 eyes were stage C. One patient had family history. Four patients were evaluated the Rb1 mutation. Routine ophthalmic examinations and ultra-wide field fundus imaging were performed on the 16 parents and 3 siblings of the 8 patients. Systemic intravenous chemotherapy was performed using the Carboplatin, Vincristine, Etoposide protocol, intra-arterial chemotherapy using Carboplatin and Melphalan, and local treatment involved cryotherapy and transpupillary thermotherapy. The mean follow-up time is 47.25 months.Results:None of the 8 children had any ocular symptoms. Six patients received intravenous chemotherapy (5-6 times), 1 patient received intra-arterial chemotherapy (3 times), and 1 patient just received local treatment. Among the 11 eyes, 9 eyes were treated with local cryotherapy and 8 eyes were treated with transpupillary thermotherapy. During the follow-up period, 2 patients had new tumor, and the average time was 6.3 months after the last chemotherapy. At the last follow-up, the tumor disappeared in 11 eyes, remained stable in 11 eyes. The eye protection rate was 100% (8/8) for patients without eyeball excision. The best corrected visual acuity was 0.1 for 3 eyes and 1.0 for 5 eyes. Three eyes were not found. One heterozygous mutation of Rb1 gene [1c.35_69del (p.T12fs)] was identified in 1 patient, and the other 3 patients were not detected. One had bilateral bulbar tuberculosis of the 16 parents, 1 had bilateral RB of the 3 siblings. They were the mother and brother of a child with bilateral RB.Conclusions:Fundus screening is helpful for the detection of early RB. The eye protection rate is high and the long-term vision prognosis is good after systemic or topical chemical drugs (IVC, IAC) and ocular topical treatment (cryopreservation and transpupillary thermotherapy).

Objective:To evaluate the effect of aerosol inhalation and airway dripping for airway humidification of patients with tracheotomy, and explore airway humidification methods suitable for China's national conditions.Methods:The documents published from January 2010 to October 2020 in The Cochrane Library, PubMed, Embase, China National Knowledge Infrastructure (CNKI) , Wanfang Data and VIP were searched by computer, including randomized controlled trials (RCTs) on the application of aerosol inhalation and airway dripping as a method of airway humidification in patients with tracheotomy. Two researchers used the quality evaluation method of Cochrane Handbook (5.1.0.) to rigorously evaluate the quality of the documents and extract data, and conducted a meta-analysis of the documents that met the quality standards.Results:A total of12 RCTs were included, with a total of 1 010 patients. The results of meta-analysis showed that the sputum viscosity in the aerosol inhalation group was lower than that in the airway dripping group [ RR=0.29, 95% CI (0.21, 0.40) , P<0.01], the incidences of airway mucosal injury, irritating dry cough and lung infection also decreased [ RR=0.34, 95% CI (0.23, 0.51) , P<0.01; RR=0.24, 95% CI (0.16, 0.38) , P<0.01; RR=0.48, 95% CI (0.38, 0.61) , P<0.01], the airway humidification effect was better than that of the airway dripping group [ RR=0.1.34, 95% CI (1.23, 1.45) , P<0.01]. Conclusions:The application of aerosol inhalation to humidify the airway in patients with tracheotomy can significantly reduce the sputum viscosity, airway mucosal injury, irritating dry cough, and the lung infection, and achieve a good airway humidification effect.

Objective:To explore the effects of health coaching technique on continuous nursing for patients with laryngopharyngeal reflux disease (LPRD) .Methods:Totally 114 LPRD patients from Beijing Tongren Hospital, Capital Medical University between July 2015 to December 2018 were selected by convenient sampling and randomized into the experimental group ( n=56) and the control group ( n=58) . Patients in the control group received routine care, while patients in the experimental group received continuous nursing with the health coaching technique on this basis. Reflux Symptom Index (RSI) , Reflux Finding Score (RFS) and the compliance behavior questionnaire for LPRD patients were used to evaluate the effects of intervention. Results:The compliance scores in the experimental group at 1 and 3 months after discharge were higher than those in the control group, and the differences were statistically significant ( P<0.01) . There was no statistically significant difference in the RFS and RSI scores between the two groups on admission ( P>0.05) ; the RFS and RSI scores in the experimental group were lower than those in the control group 3 months after discharge from the hospital, and the differences were statistically significant ( P<0.01) . Conclusions:The application of health coaching technique to continuous care of patients with LPRD after surgery can improve the patient's compliance behavior as well as their prognosis.
