OBJECTIVE To report the diagnosis and treatment process of 1 case of Streptomyces thermoviolaceus pneumonia， and provide reference for the diagnosis and treatment of this type of infection by combining literature on Streptomyces pneumonia. METHODS A case study was conducted on a patient with S. thermoviolaceus pneumonia treated at the First Affiliated Hospital of Army Medical University. Additionally， a systematic literature review of Streptomyces pneumonia cases was performed. RESULTS The patient with S. thermoviolaceus presented with left lung consolidation and mass-like opacity. Initial diagnosis via matrix-assisted laser desorption/ionization time-of-flight mass spectrometry failed， but 16S rRNA gene amplification and sequencing confirmed S. thermoviolaceus as the causative pathogen. Six-month therapy with Amoxicillin capsules （1 g orally， three times daily） resulted in near-complete lesion resolution. The literature analysis of Streptomyces pneumonia revealed that 13 patients with Streptomyces pneumonia were included （including the patient reported in the article）， age range of 18-77 years， more males （8 cases）， and mostly suffering from underlying diseases. In terms of clinical symptoms， all enrolled cases exhibited cough， and some cases were accompanied by variable dyspnea. Imaging findings included that there was no characteristic predilection site for Streptomyces pneumonia lesions， and CT images commonly showed lung consolidation and bilateral nodules. Definitive diagnosis relied on 16S rRNA sequencing. Treatment regimens included tetracyclines， β -lactam drugs combined with enzyme inhibitors， ceftriaxone， aminoglycosides， macrolides， or carbapenems， administered for prolonged duration （6 months）. Follow-up indicated a good prognosis， and only one mortality occurred. CONCLUSIONS 16S rRNA gene sequencing should be prioritized for diagnosing S. pneumonia. Effective antimicrobial options include tetracyclines，β-lactam drugs combined with enzyme inhibitors， ceftriaxone， aminoglycosides， macrolides， and carbapenems. Prolonged therapy correlates with favorable prognosis.

Objective: To investigate the trends in incidence and mortality of esophageal cancer in cancer registration areas of Anhui Province from 2014 to 2020, so as to provide the basis for formulating prevention and control measures. Methods: The incidence and mortality data of esophageal cancer in Anhui Province from 2014 to 2020 was collected through the Cancer Registry in Anhui Province. The crude incidence and crude mortality were calculated. The Chinese population-standardized rate was standardized using the age structure of the standard population from the Fifth National Population Census in 2000. The trends in incidence and mortality of esophageal cancer were analyzed using the average annual percent change (APPC), stratified by genders, urban/rural areas, and ages. Results: In Anhui Province, the rank of esophageal cancer incidence dropped from the third in 2014 to the sixth in 2020. Concurrently, the crude incidence and Chinese population-standardized incidence declined from 28.74/100 000 and 20.74/100 000 to 19.23/100 000 and 10.59/100 000, respectively (AAPC=-5.846%, -9.658%, both P<0.05). The mortality rank remained stable at the fourth in 2014 and 2020, while the crude mortality and Chinese population-standardized mortality decreased from 19.96/100 000 and 14.09/100 000 to 16.00/100 000 and 8.41/100 000, respectively (AAPC=-3.542%, -7.784%, both P<0.05). The Chinese population-standardized incidence (AAPC=-9.682%, -9.188%, -6.175% and -12.575%, all P<0.05) and Chinese population-standardized mortality (AAPC=-7.734%. -7.447%. -5.366% and -10.209%, all P<0.05) showed declining trends in males, females, urban, and rural areas, respectively. From 2014 to 2020 in Anhui Province, the crude incidence and mortality of esophageal cancer generally increased with age. However, significant declining trends were observed in crude incidence (AAPC=-12.779%, -11.701%, -11.955% and -5.751%, all P<0.05) and crude mortality (AAPC=-12.255%, -11.120%, -10.985% and -5.751%, all P<0.05) for the age groups of 40-<50, 50-<60, 60-<70, 70-<80 years. A significant declining trend in crude incidence was also seen in the ≥80 years group (APPC=-6.334%, P<0.05), but the trend in crude mortality was no statistically significant (P>0.05). Conclusion In registration areas of Anhui Province, the incidence and mortality of esophageal cancer exhibited a declining trend from 2014 to 2020, calling for focused attention on the middle-aged and elderly population and enhanced health behaviors such as tobacco and alcohol control.

Objective:To systematically integrate qualitative research on the real experience and management of cancer pain in adult cancer patients, so as to provide reference for improving the management of cancer pain in adult cancer patients and reducing their cancer pain.Methods:Qualitative research literature on the real experience and management of cancer pain in cancer patients was systematically searched in Cochrane Library, PubMed, Web of Science, CINAHL, Embase, ProQuest, Scopus, China Biomedical Database, China National Knowledge Infrastructure, Wanfang Data, and VIP. The search period was from database establishment to August 2023. The literature was evaluated using the quality evaluation criteria for qualitative research of the Joanna Briggs Institute Evidence-Based Health Care Center. The aggregation Meta-synthesis method was used to integrate and summarize research results.Results:A total of 16 articles were included, and 78 results were extracted to form 11 categories, which were summarized into four integrated results of the cognitive status of adult cancer patients towards cancer pain, the impact of cancer pain on patients, self-management strategies for cancer pain, and medical experiences related to cancer pain.Conclusions:Adult cancer patients face obstacles in alleviating cancer pain, such as lack of awareness of cancer pain, negative impacts, inadequate self-management strategies, and poor medical experience. Patients need to improve their self-management strategies, and the country and medical institutions should provide comprehensive support to enable patients and clinical medical and nursing staff to manage cancer pain.

β-elemene has been observed to exert inhibitory effects on a multitude of tumors,primarily through multiple pathways such as the inhibition of cancer cell proliferation and the induction of apoptosis.The present study is designed to elucidate the role and underlying mechanisms of β-elemene in the thera-peutic intervention of non-small cell lung cancer(NSCLC).Both in vitro and in vivo experimental models corroborate the inhibitory potency of β-elemene on NSCLCs.Our findings indicate that β-elemene fa-cilitates the maturation of miR-127-3p by inhibiting CBX8.Functioning as an upstream regulator of MAPK4,miR-127-3p deactivates the Akt/mTOR/p70S6K pathway by targeting MAPK4,thereby inducing autophagy in NSCLCs.Additionally,β-elemene augments the packaging of miR-127-3p into exosomes via SYNCRIP.Exosomal miR-127-3p further stimulates M1 polarization of macrophages by suppressing ZC3H4.Taken together,the detailed understanding of the mechanisms through which β-elemene in-duces autophagy in NSCLCs and facilitates M1 polarization of macrophages provides compelling scientific evidence supporting its potential utility in NSCLC treatment.

Objective:To construct a rehabilitation nursing program for total knee arthroplasty (TKA) patients with kinesiophobia based on capacity, opportuniy, motivation-behavior (COM-B) theoretical model, and to provide reference for clinical staff to implement rehabilitation treatment.Methods:From August to December 2023, literature analysis was used to construct a preliminary program, combined the COM-B theoretical model with the rehabilitation exercise guidelines and expert consensus. The rehabilitation nursing program for TKA patients with kinesiophobia was formed through 2 rounds of Delphi expert correspondence consultation, and the analytic hierarchy process was used to calculate the weight of each item.Results:A total of 15 experts were included, including 4 males and 11 females, aged (45.80 ± 5.72) years old. The effective recovery rate of the 2 rounds of expert correspondence questionnaires were 15/15, the expert authority coefficients were 0.860 and 0.875, and the Kendall coordination coefficients were 0.155 and 0.172, and the differences were statistically significant ( χ2 = 97.70, 105.91, both P<0.01). The final rehabilitation nursing program for TKA patients with kinesiophobia included 3 primary indexes, 8 secondary indexes and 25 tertiary indexes. Conclusions:The rehabilitation nursing program for TKA patients with kinesiophobia constructed based on COM-B theoretical model is scientific and practical, and can provide a practical basis for clinical staff.

Objective:To explore the effects of midazolam oral solution on preoperative sedation, hemodynamics, and awakening agitation in children undergoing tonsillectomy combined with adenoidectomy.Methods:A total of 267 pediatric patients who underwent tonsillectomy combined with adenoidectomy at the Children′s Hospital Affiliated to Zhejiang University School of Medicine from January to September 2022 were randomly divided into a low-dose group ( n=89), a high-dose group ( n=89), and a control group ( n=89) using a random number table method. 30 minutes before anesthesia, the low-dose group received 0.25 mg/kg of midazolam orally, the high-dose group received 0.5 mg/kg of midazolam orally, and the control group received 5 ml of 10% glucose mixture orally. We compared the extubation time and post anesthesia recovery room (PACU) retention time among three groups of pediatric patients; Mean arterial pressure (MAP) and heart rate (HR) levels before administration and 10, 20, and 30 minutes after administration; The Yale Modified Perioperative Anxiety Scale (mYPAS) score and restlessness incidence were measured before administration and 10 and 60 minutes after administration. Results:The retention time of PACU in the low-dose group was shorter than that in the high-dose group ( P<0.05), and there was no statistically significant difference between the low-dose group and the control group ( P>0.05). At 10, 20, and 30 minutes after administration, the levels of MAP and HR in the low-dose and high-dose groups were lower than before administration (all P<0.05), and at 10, 20, and 30 minutes after administration, the levels of MAP and HR in the low-dose and high-dose groups were lower than those in the control group (all P<0.05). Before administration, there was no statistically significant difference in mYPAS scores among the three groups (all P>0.05); At 10 and 60 minutes after administration, the mYPAS scores of the low-dose and high-dose groups were lower than before administration, and the mYPAS scores of the low-dose and high-dose groups were lower than those of the control group (all P<0.05); At 10 and 60 minutes after administration, there was no statistically significant difference in mYPAS scores between the control group and before administration (all P>0.05), while there was no statistically significant difference in mYPAS scores between the low-dose and high-dose groups (all P>0.05). There was no statistically significant difference in the incidence of agitation among the three groups ( P>0.05). Conclusions:Preoperative oral administration of 0.25 mg/kg or 0.5 mg/kg midazolam can effectively alleviate preoperative anxiety and improve hemodynamics in children undergoing tonsillectomy combined with adenoidectomy. However, due to the fast metabolism of midazolam, its effect on improving postoperative restlessness during the recovery period is not significant. The 0.25 mg/kg dose of midazolam can reduce the retention time of PACU compared to the 0.5 mg/kg dose, which is worthy of clinical recommendation.

Objective:To construct a prospective benefit evaluation model,and to explore its effect and value in the management of micro-injection pumps and infusion pumps in thoracic surgery.Methods:A prospective benefit evaluation model was constructed through three stages:data collection,data analysis,and data application.A total of 11 medical syringe pumps(6 micro-injection pumps and 5 infusion pumps)in clinical use in the Department of Thoracic Surgery of Chongqing General Hospital from 2021 to 2023 were selected,and the conventional management method was adopted during the equipment use period from January to December 2021,and the prospective benefit evaluation model management was adopted during the equipment use period from January 2022 to December 2023(referred to as prospective management).The equipment utilization efficiency and equipment operation benefit increase of the two management methods were compared.Results:The equipment availability rate,annual start-up rate,rate of return and utilization rate of equipment utilization efficiency using prospective management method were(0.98±0.12)%,(2.14±0.28)%,(1.31±0.19)%and(25.14±1.27)%,respectively,which were higher than those of conventional management method,and the difference was statistically significant(t=3.525,3.463,7.591,11.779,P＜0.05).The increase of equipment management cost,cost-effectiveness and social benefit using prospective management method were(0.65±0.23)%,(5.92±1.14)%and(6.31±1.29)%,respectively,the increase of management cost was lower than that of conventional management method,while the increase of cost-effectiveness and social benefit were higher than those of conventional management method,and the difference was statistically significant(t=3.099,3.763,4.798,P＜0.05).Conclusion:The application of prospective benefit evaluation model to the management of equipment of micro-injection pumps and infusion pumps in thoracic surgery can improve equipment utilization efficiency,strengthen equipment management quality,and improve the increase of equipment efficiency.

Objective:To study the dosimetric differences of hippocampal-avoidance whole brain radiotherapy(HA-WBRT)between non-uniform 9-fields intensity-modulated radiotherapy-flatten filter(9F-IMRT-FF)and 9-fields intensity-modulated radiotherapy-flatten filter-free(9F-IMRT-FFF)mode.Methods:From January to December 2023,the simulated images of computed tomography(CT)location of 20 patients with intracranial metastases who had completed whole-brain radiotherapy at the Department of Radiotherapy of Chengde Central Hospital were selected.The radiotherapy plans of two kinds of modes of brand-new 9F-IMRT-FF and 9F-IMRT-FFF were redesigned in the planning system.The differences of dosimetric parameters of the two kinds of mode plans were compared,as well as the differences of irradiation efficiency of accelerator.Results:The exposure dose(D2%)of 2%volume of target region of planned target volume(PTV)of 9F-IMRT-FFF mode was significantly lower than that of 9F-IMRT-FF mode(t=-2.496,P<0.05).The exposure dose(D100%)of 100%volume of target region,the maximum dose(Dmax)and the mean dose(Dmean)of the left side of hippocampus of 9F-IMRT-FFF mode plan were significantly lower than those of 9F-IMRT-FF mode plan,with statistically significant(Z=-3.179,-3.018,-2.145,P<0.05),respectively.The D100%and Dmax of the right side of hippocampus of 9F-IMRT-FFF mode plan were significantly lower than those of 9F-IMRT-FF mode plan,with statistically significant(Z=-3.099,-3.260,P<0.05),respectively.The monitor unit(MU)value of 9F-IMRT-FFF mode plan increased by 25%than that of 9F-IMRT-FF mode plan,while the treatment time of 9F-IMRT-FFF mode plan shortened 38%than that of 9F-IMRT-FF mode plan,with statistically significant(t=-9.664,-13.312,P<0.05),respectively.Conclusion:Both the non-uniform 9F-IMRT-FF and the 9F-IMRT-FFF can meet the clinically requirement.The 9F-IMRT-FFF has better modulation capabilities in beams,which has more advantages in reducing the dose of radiotherapy for hippocampus,and reducing treatment time,and increasing treatment efficiency.

Objective:To compare the clinical value of digital breast tomosynthesis (DBT) localization and stereotactic positioning biopsy of breast lesions.Methods:This study was a cross-sectional study. Totally of 250 patients who underwent breast biopsy at Shenzhen People′s Hospital, Luohu District People′s Hospital and Peking University Shenzhen Hospital between August 2021 to October 2023 was analyzed retrospectively, including 136 cases of DBT-guided biopsy (DBT-guided group) and 114 cases of stereotactic-guided biopsy (stereotactic-guided group). The stereotactic-guided biopsy methods included core needle biopsy (CNB) and wire positioning. The DBT-guided biopsy methods included CNB, wire positioning and vacuum-assisted breast biopsy (VABB). The χ2 test or Mann-Whitney U test was used to compare the puncture success rate, operation time, localization time, puncture time, number of first valid localization phases obtained, number of exposures, and complications of different biopsy methods between 2 groups. Results:In the wire positioning biopy, the puncture success rate was 100% (33/33) in DBT-guided group and 96% (48/50) in the stereotactic-guided group, with no statistically significant difference between the two groups ( P=0.515). Compared to the stereotactic-guided group, the operation time and localization time were shorter, and the number of first valid localization phases obtained, number of exposures were fewer in the DBT-guided group( P<0.05). The incidence of complications was lower in both the DBT-guided group and the stereotactic-guided group, with no statistically significant difference ( P=0.871). In CNB, both the DBT-guided group and the stereotactic-guided group had higher puncture success rates, with no statistically significant difference ( P=0.080). Compared to the stereotactic-guided group, the operation time, localization time and puncture time were shorter, and the number of first valid localization phases obtained, number of exposures were lower in the DBT-guided group, and the difference between the two groups were statistically significant ( P<0.05). The incidence of complications was lower in both the DBT-guided group and the stereotactic-guided group, with no statistically significant difference ( P=0.627). Twenty-one cases received DBT-guided VABB, with an operation time of (19.90±3.38) min, a localization time of 6.00 (6.00, 7.00) min, a puncture time of (13.42±3.28) min, the number of first effective localization phases obtained was 1.00 (1.00, 1.00) time, the number of exposures was 4.00 (3.50, 5.00) times, and one case experienced severe pain after puncture. Conclusion:Compared with stereotactic-guided biopsy, DBT-guided biopsy can reduce operation time and exposure times, and can target more types of breast lesions, with higher clinical application value.
