Implementation science (IS) aims to systematically analyze and address the real-world gaps from evidence to practice and the influencing factors of the context. It is necessary to carry out qualitative research to gather relevant implementation outcomes. Nevertheless, traditional qualitative analysis has issues such as consuming a great deal of time and energy, and it is unable to promptly provide the crucial data required for implementation science research. The Rapid Qualitative Analysis (RQA) method, through semi-structured interviews and the adoption of techniques such as immediate data condensation and matrix analysis, can effectively shorten the cycle of qualitative data collection and data processing. RQA can promptly identify social determinants of health such as structural barriers, facilitators, and the behavioral characteristics of target groups. It provides a real-time basis for public health decision-making, the interpretation of complex social phenomena, and the process and effectiveness evaluation of research projects. Although RQA is difficult to conduct in-depth theoretical analysis based on grounded theory, its efficiency and flexibility make it the preferred tool for large-scale and time-sensitive research. Thus, it has been widely applied in implementation science research. This paper sorts out the core concepts and commonly used technical methods of RQA, as well as the differences between RQA and traditional qualitative analysis. It also explores the applications of RQA in intervention optimization, process evaluation, and implementation outcome evaluation. By integrating specific cases, this paper clarifies its application value in the field of implementation science. In the future, it is advisable to explore the integration of RQA with technologies such as artificial intelligence and big data, in order to bridge the gap between the transformation of scientific research achievements into practice. Under circumstances of limited resources or tight time constraints, RQA can be used to efficiently conduct implementation science research, providing convenient and scientific methodological and technical support for accelerating evidence-based practice.

Objective:This study aims to explore the clinical effectiveness of a novel treatment method for refractory laryngeal contact granuloma, involving CO2 laser excision with local pedicled mucosal flap transfer combined with type A botulinum toxin injection. Methods:A retrospective analysis was conducted on 18 patients with refractory laryngeal contact granuloma who visited Department of Otolaryngology Head and Neck Surgery, Nanjing Tongren Hospital, School of Medicine, Southeast University from January 2021 to June 2023. These patients underwent CO2 laser excision of the granuloma with local pedicled mucosal flap transfer combined with type A botulinum toxin injection. During follow-up, electronic laryngoscopy were performed at 1, 3, 6, and 12 months postoperatively, and local laryngeal mucosa, voice quality, and pharyngeal discomfort symptoms were evaluated. Results:Postoperative electronic laryngoscopy revealed the disappearance of granulomas in all 18 patients. Symptoms such as hoarseness, foreign body sensation in the throat, and cough were significantly improved. No complications were observed systemically or locally. No recurrence was observed during one-year follow-up. Conclusion:CO2 laser excision of granuloma with local pedicled mucosal flap transfer combined with type A botulinum toxin injection could eliminate the lesion, restore the integrity of the vocal fold lining, preserve the perichondrium, and provide a time window for mucosal flap recovery. This approach adheres to the principle of preserving normal mucosa, achieves a high cure rate, and is therefore worthy of widespread promotion and application in clinical practice.

Objective:To explore the the application and outcomes of microscopic vocal cord shortening with retrodisplacement of anterior commissure in voice feminization surgery.Methods:We conducted a retrospective analysis of 296 patients(including 3 cases of pseudohermaphroditism and 293 transgender women)who underwent this procedure at the Voice Center of Nanjing Tongren Hospital of Otolaryngology-Head and Neck Surgery between November 2014 and August 2023. The patients, aged 18-50 years (mean age of 28.3±14.5) underwent feminizing laryngoplasty via transoral microsurgery, involving resection of the superficial lamina propria of the anterior vocal cords and subglottic tissues of the anterior commissure, followed by vocal ligament plication to achieve vocal cords shortening and anterior commissure retrodisplacement. Patients adhered to a1-month voice rest postoperatively and subsequently underwent speech rehabilitation training. Subjective/objective voice analyses, aerodynamic evaluations, and stroboscopic examinations were performed at 3, 6, and 12 months postoperatively to assess the effectiveness of voice feminization.Results:All surgeries were performed successfully and 94.3% (279/296) of the patients reported satisfaction at the end of the one-year follow-up. For effective cases, fundamental frequency (F 0) increased by 57.42±16.72 Hz compared to baseline. Postoperative acoustic/aerodynamic parameters and stroboscopic findings of vocal cord mucosal wave motion remained within normal ranges. These results indicated that this voice feminization surgery combined with postoperative pronunciation training achieved natural and feminine vocal characteristics. Conclusion:The combination of vocal cord shortening and anterior commissure retrodisplacement, along with postoperative pronunciation training, represents an effective surgical strategy for achieving a natural feminine voice.

Neuroinflammation is a common pathological feature of neurodegenerative diseases （NDs）. Microglia （MG）， a resident macrophage in the brain with a unique developmental origin， is the core driver of neuroinflammation. It can participate in the occurrence and development of NDs through different polarization states and play a key role in regulating neurogenesis and synapse shaping and maintaining homeostasis. MG can be divided into M1 pro-inflammatory phenotype and M2 anti-inflammatory phenotype according to its function. The inflammatory mediators released by the M1 phenotype can lead to nerve degeneration and myelin sheath damage， while the activation of the M2 phenotype is required to inhibit the inflammatory response and promote tissue repair. With the advantages of multi-pathway， multi-target， and bidirectional regulation， traditional Chinese medicine can regulate the polarization balance of MG and has dual effects on NDs such as Alzheimer's disease， Parkinson's disease， and multiple sclerosis. The active components of traditional Chinese medicine and its compound can inhibit the activation of MG by regulating phosphatidylinositol-3-kinases/protein kinase B（PI3K/Akt）， NOD-like receptor thermal protein domain associated protein 3（NLRP3）， signal transducer and activator of transcription factor1（STAT1）， nuclear transcription factor kappa B（NF-κB）， and other pathways， promote the polarization of M1 phenotype to M2 phenotype， reduce the expression of interleukin（IL）-6， tumor necrosis factor-α（TNF-α）， and other pro-inflammatory factors， and increase the secretion of IL-10， arginase-1（Arg-1）， and other anti-inflammatory factors. It can also reduce β-amyloid deposition and tau protein expression in Alzheimer's disease， alleviate dopaminergic neuronal damage in Parkinson's disease， and relieve demyelination， inflammatory cell infiltration， and related clinical symptoms of multiple sclerosis. The bidirectional regulation of the M1/M2 polarization balance of MG by traditional Chinese medicine is a potential strategy for the treatment of NDs. This paper focused on the targets of the regulation of MG polarization balance by traditional Chinese medicine monomer and its compound in the treatment of NDs， so as to further study and summarize the existing research results and provide ideas and basis for the future treatment of NDs.

Objective To investigate the clinical effect of microflap suture under self-retaining laryngoscope on benign vocal cord diseases.Methods A total of 115 patients with benign vocal cord diseases who underwent surgical treatment in the Binhai People's Hospital Affiliated to Kangda College of Nanjing Medical University and Nanjing Tongren Hospital Affiliated to School of Medicine of Southeast University were enrolled in this retrospective study.According to the surgical treatment methods,the patients were divided into observation group(58 patients were treated with microflap suture under self-retaining laryngoscope)and control group(57 patients received conventional surgery).The treatment effect,Voice Handicap Index-10(VHI-10)score,the scales of overall grade(G),roughness(R),breathiness(B),asthenian(A)and strain(S),and voice related parameters were compared between the two groups.Results The overall treatment effect of the observation group was significantly better than that of the control group(P＜0.05).There were no significant differences in the VHI-10 score functional score,physiological score,emotional score,VHI-10 score,GRBAS score,longest phonation time,recording fundamental frequency,fundamental frequency perturbation,amplitude perturbation,or voice harmonic ratio before treatment between the two groups(P＞0.05).After treatment,the VHI-10 score functional score,emotional score,total score),GRBAS score,the value of fundamental frequency perturbation and voice harmonic ratio in the observation group were significantly lower than those in the control group(P＜0.05);the longest phonation time in the observation group was significantly longer than that in the control group(P＜0.05).Conclusion Microflap suture under self-retaining laryngoscope is an effective treatment for benign vocal cord diseases,and the voice recovery is better after surgery.

Objective:To understand the emotional experiences of Intensive Care Unit(ICU)nurses facing pa-tient deaths,particularly those exhibiting signs of vicarious trauma.Methods:Employing a descriptive phenomeno-logical research design,sixteen ICU nurses with signs of vicarious trauma(scores above the theoretical median on the Disaster Responders Vicarious Trauma Questionnaire)were selected for in-depth interviews.The interviews fo-cused on their reference frameworks,self-capacities,resources,psychological needs,cognitive schemas,and image-ry.Data were analyzed using Colaizzi's seven-step methodology.Results:The emotional experiences of ICU nurses in the face of patient deaths were categorized into two themes,namely self-defense mechanisms under stress and e-motional exhaustion following prolonged exposure.The first theme includes unconscious temporary closures and personalized emotional reactions.The latter encompasses mirroring emotions of patients and their families,the sense of finality triggered by handling deceased bodies,feelings of helplessness in comforting families,unavoidable re-sponsibility,diminished sense of professional belonging,and strained family relationships.Conclusion:This study highlights the two-fold emotional impact on ICU nurses dealing with patient deaths,namely self-defense under stress and emotional exhaustion following prolonged immersion.

【Objective】 To investigate the incidence of clinical massive blood transfusion in hospitals, the proportion of departments conducted massive blood transfusion and the current situation of component transfusion, so as to provide a theoretical basis for medical decision-making and further research on massive blood transfusion. 【Methods】 The basic clinical data and transfusion of blood components were retrospectively collected from 489 patients (514 occasions) who received massive blood transfusion at Sun Yat-sen Memorial Hospital of Sun Yat-sen University from Jan. 1 2014 to Dec. 31 2018. 【Results】 The incidence of massive blood transfusion during the 5-year period was 1.2/1 000 inpatients (95%CI: 1.1-1.3), and the 30-day all-cause mortality was 21.88%; in the departments where massive blood transfusion occurred, the mortality rate was the highest in the trauma emergency department (60%), followed by intensive care unit (56.25%) and other surgery department (46.67%), while there was no death in the obstetric department. All patients received red blood cells [median 14 U (11.5-19.13)] and plasma [median 1 600 mL (1 200-2 200)], of which 47% received platelet [median 0 U (0-10)] and 32.68% received cryoprecipitate [0 U (0-10)]. The results of logistics regression analysis of all-cause mortality risk showed that compared with the youth group, the risk of all-cause death at 30 days of elderly patients over 65 years old (65 < age ≤79 years old: OR=2.471, 95%CI=[1.044, 5.847], P<0.05; patients with age > 80 years old: OR=7.563, 95%CI=[1.587, 36.049], P<0.05) and 24-hour RBC infusion volume greater than 18 U (18≤RBC<27: OR=2.948 95%CI=[1.592, 5.462], P<0.05; RBC≥28: OR=3.992, 95%CI=[1.178, 13.536], P<0.05) was higher. 【Conclusion】 A dynamic definition should be included in massive transfusion studies. If only a 24-hour RBC infusion volume ≥18 U was used as the mass transfusion definition, about 68% of cases would be lost. The mortality rate of patients with massive blood transfusion was higher, and the incidence of massive blood transfusion was higher in the departments of cardiac surgery, general surgery and orthopedics surgery. More attention should be paid to the increasing number of female patients with massive blood transfusion. In addition, the risk of 30-day all-cause death was highest in elderly patients over 65 years of age and those with a 24-hour erythrocyte transfusion level of ≥18 U.

The basic data of menarche age of women born between 1951 and 2005 were obtained. The changes and rules were analyzed by taking 1 year, 5 years and 10 years as nodes.Results:Totally 46 and conducted under standardized survey procedures and quality control standards 928 pepole (24 450 Han and 22 478 Mongolian) were recruited, the survey response rate was 96.09% (46 928/48 836). In one-year-period analysis, the menarche age gradually decreased from 1951 to 2005. The mean menarche age of Han and Mongolian women changed from (16.22±0.52) years and (15.86±1.24) years in 1951 to (12.37±1.15) years and (12.33±0.98) years in 2005, respectively. The mean menarche age of Han and Mongolian women decreased 3.85 years and 3.54 years. The trend of the mean menarche age's change showed a significant negative correlation with the years (all P<0.000 1). In five-year-period analysis, the mean menarche age of Han and Mongolian women changed from (15.54±1.45) years and (15.53±1.48) years from 1951 to 1955 to (12.41±0.97) years and (12.47±0.96) years from 2001 to 2005, the mean menarche age decreased 3.13 years (3.41 months ahead of schedule every 5 years on average) and 3.06 years (3.34 months ahead of schedule every 5 years on average) in Han and Mongolian women respectively. In ten-year-period analysis, the mean menarche age of Han and Mongolian women changed from (15.79±0.95) years and (15.53±1.33) years from 1951 to 1960 to (12.41±0.97) years and (12.47±0.96) years from 2001 to 2005, the mean menarche age decreased 3.38 years (6.76 months ahead of schedule every 10 years on average) and 3.06 years (6.12 months ahead of schedule every 10 years on average) in Han and Mongolian women respectively. During the 15 years from 1951 to 1965, 1966 to 1970, 1971 to 1990, and 1991 to 2000, they were concentrated at the ages of 15-16, 14-15, 13-14, and 12-13, respectively. The proportion of women at 11 years, 12 years and 13 years menarche age were 26.79% (457/1 706), 73.27% (1 250/1 706), and 92.85% (1 584/1 706) during 2001—2005 in Han women, while the proportion were 23.25% (653/2 809), 62.01% (1 742/2 809), and 90.14% (2 532/2 809) in Mongolian women. Conclusion:The menarche age decreased in Han and Mongolian women from 1951 to 2005, and the ethnic groups tended to be the same. It is recommended to start adolescent education at the age of 8-9 years and pay attention to the changing pattern of early onset of menarche.
