ObjectiveTo analyze the research hotpots and development trends of international nursing ethical decision-making in the past 10 years by bibliometric methods. MethodsLiterature related to nursing ethical decision-making published in the Web of Science core collection database from 2014 to 2023 was retrieved. VOSviewer 1.6.18 software was utilized to visually present and analyze data regarding the number of publications， journal sources， countries of origin， author information， research institutions， key terms， co-cited references， and others. ResultsA total of 149 articles were included， involving 85 source journals， of which Nursing Ethics and BMC Medical Ethics were the most prolific. The number of publications on nursing ethical decision-making showed an overall upward trend， with the United States leading other countries in the number of publications. These publications involved 567 authors from 302 research institutions， and the degree of inter-institutional collaboration was relatively low. Keyword clustering， timeline overlay， and density analysis revealed that current research hotspots and trends included the ethical issues and decision-making in clinical nursing practice， the ethical decision-making level and competence of university nursing undergraduates， the ethical decision-making of nursing managers， and ethical decision-making dilemmas encountered by nursing staff during public health emergencies. ConclusionResearch on nursing ethical decision-making is gradually deepening but remains fragmented， lacking sustainability and collaboration. The ethical decision-making levels and competencies of university nursing students， as well as the field of ethical decision-making among nursing managers， may emerge as novel research hotspots in the future. Henceforth， it is necessary to strengthen in-depth exchanges among authors and institutions， pay close attention to international research frontiers， and enhance both the depth and breadth of research.

This case report highlights the successful treatment of moderate-to-severe thyroid-associated ophthalmopathy(TAO) with teprotumumab in a patient who had previously failed multiple therapies, including intravenous steroid pulse therapy, local thyroid injections of cyclophosphamide, octreotide and dexamethasone, tocilizumab treatment, total thyroidectomy, and orbital radiation. Despite these interventions, there was no improvement in TAO. Following treatment with teprotumumab, the patient experienced a reduction of 5 mm in left eye proptosis and 4 mm in right eye proptosis, a 6-point decrease in the clinical activity score(CAS), a 2-point reduction in the diplopia score, and a significant improvement in quality of life, with sustained effects lasting 72 weeks. The treatment was well tolerated, with mild side effects including muscle spasm, fatigue, and dryness of the skin and nasal mucosa. This case report aims to raise clinical awareness regarding efficacy and safety of teprotumumab.

To understand the pathogenicity and drug resistance of swine-derived E.coli and its bio-logical characteristics in some areas in Hebei,E.coli was isolated and identified from diarrheal fe-ces of piglets collected from swine farms,and the isolated strains were subjected to drug sensitivity test,detection of the ability to form biofilm,pathogenicity test,virulence gene test,drug resistance gene test,and identification of phylogenetic subgroups.The results showed that a total of 35 patho-genic E.coli strains were isolated from the feces of diarrheic piglets,and most of the isolates were multidrug-resistant,and were resistant to at least three antibiotics,including amoxicillin(88.57％),ampicillin(88.57％),doxycycline(88.75％),sulfisoxazole(77.17％),lincomycin(100％),and chloramphenicol(100％);the isolates were severely resistant.The isolates all carried virulence genes,with a total of five virulence genes detected,namely,EAST1(77.14％),eaeA(17.14％),stx2e(5.71％),LT(2.86％),and STb(2.86％),and the isolates also carried multi-re-sistance genes,with a total of five virulence genes detected,namely,bla TEM-1(65.71％),bla CTX-M(20.00％),tetA(82.86％),tetB(14.29％),aadA2(17.14％),aac(6')-Ib(14.29％),qnrS(17.14％),sul 1(40.00％),sul2(34.29％),and floR(60.00％);the phylogenetic grouping showed that the isolates had a high proportion of group B1 and group A;and all 35 isolates showed differ-ent pathogenicity after infection of mice.This study provides a reference for the selection of effec-tive therapeutic drugs and the development of prevention and control programs for swine-origin pathogenic E.coli in Hebei Province.

OBJECTIVE: To propose a machine learning-based method for predicting the trajectories during manual acupuncture manipulation (MAM), aiming to improve the precision and consistency of acupuncture practitioner' operation and provide the real-time suggestions on MAM error correction. METHODS: Computer vision technology was used to analyze the hand micromotion when holding needle during acupuncture, and provide a three-dimensional coordinate description method of the index finger joints of the holding hand. Focusing on the 4 typical motions of MAM, a machine learning-based MAM trajectory predictive model was designed. By integrating the changes of phalangeal joint angle and hand skeletal information of acupuncture practitioner, the motion trajectory of the index finger joint was predicted accurately. Besides, the roles of machine learning-based MAM trajectory predictive model in the skill transmission of acupuncture manipulation were verified by stratified randomized controlled trial. RESULTS: The performance of MAM trajectory predictive model, based on the long short-term memory network (LSTM), obtained the highest stability and precision, up to 98%. The learning effect was improved when the model applied to the skill transmission of acupuncture manipulation. CONCLUSION The machine learning-based MAM predictive model provides acupuncture practitioner with precise action prediction and feedback. It is valuable and significant for the inheritance and error correction of manual operation of acupuncture.

BackgroundPostoperative cognitive dysfunction （POCD） is a common complication in elderly patients after surgery， and has a great impact on postoperative rehabilitation of patients. ObjectiveTo explore the effect of mindfulness-based therapy on cognitive function and sleep quality in elderly patients after surgery under local anesthesia， so as to provide references for reducing their incidence risk of POCD and improving sleep quality. MethodsThe simple random sampling method was utilized to select 78 elderly patients who underwent surgery under local anesthesia in The Third Hospital of Mianyang from March 2022 to March 2023. Participants were assigned into study group and control group， each with 39 cases. All patients were subjected to conventional treatment and nursing interventions， and study group added mindfulness-based therapy on this basis. Mini-Mental State Examination （MMSE） was administered to patients on 1 day before surgery， and on the 1^st， 3^rd and 5^th day after surgery. Pittsburgh Sleep Quality Index （PSQI） was employed on 1 day before surgery and on the 3^rd day after surgery. ResultsMMSE scores revealed a significant time effect， group effect and time×group interaction effect （F=78.251， 197.071， 371.915， P<0.05）. Analysis of simple effect denoted that study group scored higher on MMSE on the 1^st， 3^rd and 5^th day after surgery compared with control group， with statistical significance （t=-3.579， -1.764， -0.253， P<0.05）. Study group reported lower incidence rates of POCD on the 1^st， 3^rd and 5^th day after surgery compared with control group， with statistical significance （χ²=2.631， 3.471， 5.135， P<0.05）. On the 3^rd day after surgery，study group scored lower on PSQI than control group（P<0.05）， and PSQI total score， sleep latency， subjective sleep quality， daytime dysfunction and hypnotic drug use factor scores of study group were lower than baseline， with statistical significance（F=43.175， 12.594， 11.092， 4.579， 3.514， P<0.01）. ConclusionMindfulness-based therapy may have certain value in reducing incidence of POCD and improving sleep quality in elderly patients who underwent surgery under local anesthesia.

Objective:To observe the effects of Zhulian stimulant type Ⅰ acupuncture on the expression of brain-derived neurotrophic factor (BDNF) and its receptor TrkB and tissue homogenate cyclic adenosine phosphate (cAMP) in rats with diabetic bladder (DCP); To explore the mechanism of Zhulian stimulant type Ⅰacupuncture on DCP.Methods:Totally 50 SD rats were divided into control group, model group, Western medicine group, ordinary acupuncture group, Zhulian stimulant type Ⅰ acupuncture treatment group (acupuncture treatment group) according to random number table method, with 10 rats in each group. DCP rat model was prepared by intraperitoneal injection of streptozotocin (STZ), except for the control group. The Western medicine group was given mecobalamine for gavage; acupoints of "Zhongji", "Sanyinjiao", "Liechou" and "Taichong" were selected. The ordinary acupuncture group was treated with ordinary acupuncture technique, and the acupuncture treatment group was treated with Zhulian stimulant type Ⅰ acupuncture, 1 time/d, 30 minutes/time. Samples were taken after 4 weeks of treatment. The maximum bladder volume, residual urine volume and wet weight of the bladder were detected. The morphology of rat bladder was observed by HE staining. The expression level of BDNF was detected by immunohistochemistry. The expression of cAMP was detected by Western blot. The level of TrkB was determined by ELISA. Real-time fluorescence quantitative PCR (RT-PCR) was used to detect the mRNA expressions of BDNF and cAMP.Results:Compared with model group, maximum bladder volume, residual urine volume and wet weight of bladder in Western medicine group, ordinary acupuncture group and acupuncture treatment group decreased ( P<0.01), and those in Western medicine group and acupuncture treatment group were lower than those in ordinary acupuncture group ( P<0.01). The expressions of BDNF mRNA and protein, cAMP mRNA and protein in Western medicine group, ordinary acupuncture group and acupuncture treatment group increased ( P<0.05), and the level of TrkB increased, and the Western medicine group and acupuncture treatment group were higher than that in ordinary acupuncture group ( P<0.05). Conclusions:Zhuliping stimulant type Ⅰ acupuncture has a protective effect on the bladder function of diabetic rats. The mechanism may be related to the up-regulation of BDNF and mRNA, TrkB, cAMP and mRNA expressions.
