Clinical practice guidelines serve as a crucial bridge linking research evidence, clinical practice, and health policy decision-making. However, the guideline domain continues to face persistent challenges, including duplicate guideline development, variable methodological quality, lack of transparent reporting, insufficient implementation and translation, and delayed updates. Focusing solely on "how to develop a high-quality guideline" is no longer sufficient to meet the modern healthcare system's demands for timely, trustworthy, actionable, and dynamically updated recommendations. The emergence of the guideline ecosystem marks a shift in guideline research and practice from a linear development process toward a more systematic governance model. Rooted in the evidence ecosystem, the guideline ecosystem has its own distinct functional positioning, encompassing recommendation formulation, clinical implementation, and life-cycle updating. Looking ahead, China should leverage guideline registries, integrated quality assessment systems, implementation science, dynamic updating mechanisms, and artificial intelligence technologies to promote the transformation of its guideline system from scale expansion to an ecosystem-based model characterized by high quality and sustainability.

OBJECTIVE To explore the effect of hydrogen peroxide disinfectant on terminal disinfection in wards of medical institutions.METHODS The surfaces of highly frequent contact objects of the wards of the First Affilia-ted Hospital of Nanchang University from which the public health center patients were discharged between Apr.2024 and Jun.2024 were respectively disinfected with 0.5％(low)and 5％(high)concentrations of hydrogen peroxide disinfecting wipes,totally 180 samples were randomly collected before and after the disinfection,and the pathogens were detected.The air of the wards from which the public health center patients were discharged be-tween Jul.2024 and Aug.2024 were disinfected with hydrogen peroxide dry mist disinfection device,and 90 sam-ples were respectively collected before and after the disinfection.Geobacillus stearothermophilus was used as the biological indicator and placed at various points within the air-disinfected wards to evaluate the disinfection level.The environmental sampling results and distribution of bacteria were observed and compared.RESULTS The qualified rates of disinfection of the object surfaces were 95.56％(86/90)and 98.89％(89/90)respectively for the low and high concentratioins of hydrogen peroxide disinfecting wipes,and there was no significant difference in the disinfection effect.Totally 120 strains of pathogens were isolated from unqualified samples before the disinfection,among which gram-negative bacteria(69.17％)were dominant,and the isolation rate of multidrug-resistant or-ganisms was 22.50％(27/120);only 1 strain of carbapenem-resistant Acinetobacter baumannii was isolated after the disinfection.The qualified rate of disinfection of air in the wards was 96.00％by 7.5％hydrogen peroxide dry mist disinfection device,the average bacterial colony counts in the air were 2 CFU/(5 min·vsl)after the dis-infection,and the killing rate of Geobacillus stearothermophilus was 100.00％by the air disinfection.CONCLUSION The hydrogen peroxide disinfectant can meet the requirement for terminal disinfection of the wards of the medical institutions,and it is portable and highly efficient.

OBJECTIVE: To investigate the short-term effectiveness of uni-portal non-coaxial spinal endoscopic surgery (UNSES) via crossing midline approach (CMA) in the treatment of free lumbar disc herniation (FLDH). METHODS: Between March 2024 and June 2024, 16 patients with FLDH were admitted and treated with UNSES via CMA. There were 9 males and 7 females with an average age of 55.1 years (range, 47-62 years). The disease duration was 8-30 months (mean, 15.6 months). The pathological segments was L _{3, 4} in 4 cases, L _{4, 5} in 5 cases, and L ₅, S ₁ in 7 cases. The preoperative pain visual analogue scale (VAS) score was 6.9±0.9 and the Oswestry disability index (ODI) was 57.22%±4.16%. The operation time, intraoperative bleeding volume, postoperative hospital stay, and incidence of complications were recorded. The spinal pain and functional status were evaluated by VAS score and ODI, and effectiveness was evaluated according to the modified MacNab criteria. CT and MRI were used to evaluate the effect of nerve decompression. RESULTS: All 16 patients underwent operation successfully without any complications. The operation time was 63-81 minutes (mean, 71.0 minutes). The intraoperative bleeding volume was 47.3-59.0 mL (mean, 55.0 mL). The length of hospital stay after operation was 3-4 days (mean, 3.5 days). All patients were followed up 1-3 months, with 15 cases followed up for 2 months and 14 cases for 3 months. The VAS score and ODI gradually decreased over time after operation, and there were significant differences between different time points ( P<0.05). At 3 months after operation, the effectiveness was rated as excellent in 12 cases and good in 2 cases according to the modified MacNab criteria, with an excellent and good rate of 100%. CT and MRI during follow-up showed a significant increase in the diameter and cross-sectional area of the spinal canal, indicating effective decompression of the canal. CONCLUSION When using UNSES to treat FLDH, choosing CMA for nerve decompression has the advantages of wide decompression range, large operating space, and freedom of operation. It can maximize the preservation of the articular process, avoid fracture and breakage of the isthmus, clearly display the exiting and traversing nerve root, and achieve good short-term effectiveness.

Objective:To investigate the clinical features of chronic spontaneous urticaria (CSU) patients with angioedema (AE) .Methods:Clinical data were collected from adult outpatients with active CSU diagnosed and treated at the First Hospital of China Medical University from January 2019 to December 2021, and analyzed retrospectively. The data included gender, age, disease duration, the presence or absence of angioedema, urticaria activity score for one day, prior treatments, previous history, family history, laboratory test results, therapeutic effect, and adverse reactions. Their treatment regimens were based on the Chinese guidelines for the diagnosis and treatment of urticaria (2018) and the American guidelines for the diagnosis and management of urticaria (2014). Statistical analysis was carried out by using Mann-Whitney U test, two-independent-sample t test, Chi-square test, corrected Chi-square test, and Fisher's exact test. Results:A total of 131 CSU patients were collected, including 78 females and 53 males. Their age at the first visit was 44.6 ± 13.3 years, and the disease duration ( M[ Q1, Q3]) was 4.0 (2.0, 10.0) months. Among these CSU patients, there were 58 with AE and 73 without AE. The disease duration was significantly longer in the CSU patients with AE (6.0 [3.0, 24.0] months) than in those without AE (3.5 [2.0, 6.0] months; Z = -2.78, P = 0.005). The urticaria activity score for one day was also significantly higher in the CSU patients with AE (5.0 [3.0, 5.3] points) than in those without AE (4.0 [3.0, 5.0] points; Z = -2.63, P = 0.008). The CSU patients with AE showed a decreased proportion of patients completely controlled by licensed-dose second-generation H1-antihistamines (sgAHs) (8.6%, 5/58) compared with those without AE (24.7%, 18/73), but an increased proportion of patients uncontrolled by licensed-dose sgAHs (91.4%, 53/58) compared with those without AE (74.0%, 54/73; Z = -2.53, P = 0.011) ; there were no significant differences in the proportions of patients completely controlled or uncontrolled by updosed sgAHs alone or combinations of 2- to 4-fold equivalent-dose sgAHs, or in the proportions of patients completely controlled or uncontrolled by combination therapy with 4-fold equivalent-dose sgAHs and non-H1-antihistamines between the CSU patients with AE and those without AE ( P > 0.05) . Conclusion:Compared with the CSU patients without AE, the CSU patients with AE had a longer disease duration, higher disease activity, a lower proportion of patients completely controlled by licensed-dose sgAHs, and a higher proportion of patients uncontrolled by licensed-dose sgAHs.

OBJECTIVE: To investigate the short-term effectiveness of transverse antecubital incision in the treatment of failed closed reduction of Gartland type Ⅲ supracondylar humeral fractures (SHFs) in children. METHODS: Between July 2020 and April 2022, 20 children with Gartland type Ⅲ SHFs who failed in closed reduction were treated with internal and external condylar crossing Kirschner wire fixation through transverse antecubital incision. There were 9 boys and 11 girls with an average age of 3.1 years (range, 1.1-6.0 years). The causes of injuries were fall in 12 cases and fall from height in 8 cases. The time from admission to operation ranged from 7 to 18 hours, with an average of 12.4 hours. The healing of the incision and the occurrence of complications such as nerve injury and cubitus varus were observed after operation; the elbow flexion and extension range of motion after removing the gypsum, after removing the Kirschner wire, and at last follow-up were recorded and compared, as well as the elbow flexion and extension and forearm rotation range of motion at last follow-up between healthy and affected sides; the Baumann angle was measured on the X-ray film, and the fracture healing was observed. At last follow-up, the effectiveness was evaluated according to the Flynn elbow function evaluation criteria. RESULTS: All incisions healed by first intention, and there was no skin necrosis, scar contracture, ulnar nerve injury, and cubitus varus. Postoperative pain occurred in the radial-dorsal thumb in 2 cases. The gypsum was removed and elbow flexion and extension exercises were started at 2-4 weeks (mean, 2.7 weeks) after operation, and the Kirschner wire was removed at 4-5 weeks (mean, 4.3 weeks). All the 20 patients were followed up 6-16 months, with an average of 12.4 months. The fracture healing time was 4-5 weeks, with an average of 4.5 weeks, and there was no complication such as delayed healing and myositis ossificans. The flexion and extension range of motion of the elbow joint gradually improved after operation, and there were significant differences between the time after removing the gypsum, after removing the Kirschner wire, and at last follow-up ( P<0.017). There was no significant difference in the flexion and extension of the elbow joint and the forearm rotation range of motion between the healthy and affected sides at last follow-up ( P>0.05). There was no significant difference in Baumann angle between the time of immediate after operation, after removing the Kirschner wire, and at last follow-up ( P>0.05). According to Flynn elbow function evaluation standard, 16 cases were excellent and 4 cases were good, the excellent and good rate was 100%. CONCLUSION The treatment of Gartland type Ⅲ SHFs in children with failed closed reduction by internal and external condylar crossing Kirschner wire fixation through transverse antecubital incision has the advantages of complete soft tissue hinge behind the fracture for easy reduction and wire fixation, small incision, less complications, fast fracture healing, early functional recovery, reliable reduction and fixation, and can obtain satisfactory results.

Objective:To explore the effect of family empowerment model based on cloud follow-up in schizophrenia patients and their main caregivers.Methods:From January 2020 to June 2021, 160 schizophrenics and their 160 main caregivers who were admitted to Shaoxing Seventh People's Hospital were selected as the study subject by convenience sampling. According to the method of random number table, the subjects were divided into control group and observation group, with 80 patients and 80 main caregivers in each group. The patients in the control group were given routine nursing, while the patients in the observation group received family empowerment nursing model based on cloud follow-up on the basis of the control group. Both groups of patients were intervened continuously for six months after enrollment. Morisky Medication Adherence Scale-8 (MMAS-8) , Personal and Social Performance Scale (PSP) , Family Environment Scale-Chinese Version (FES-CV) , Self-Perceived Burden Scale (SPBS) , Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS) were used to evaluate the drug compliance, personal social function, family function of the two groups of patients, disease burden and negative emotions of main caregivers.Results:After six months of intervention, the medication compliance of observation group was better than control group, the difference was statistically significant ( P<0.05) . The PSP score of patients in the observation group was higher than that of the control group, and the FEC-CV scores in all dimensions of the observation group were better than that of the control group, with statistically significant differences ( P<0.05) . After intervention, the disease burden, SAS and SDS scores of the main caregivers in the observation group were lower than those in the control group, with statistically significant differences ( P<0.05) . Conclusions:The family empowerment model based on cloud follow-up can improve the treatment compliance, personal social function and family environment of schizophrenics, and relieve the disease burden and negative emotions of the main caregivers, which is worthy of clinical practice.

A 3-year-old girl was hospitalized for cough and asthma for 2 days, and fever and anuria for 1 day in Department of Pediatrics, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology in January 2019.Retrospective analysis was used.She developed end-stage renal disease and received peritoneal dialysis 6 months ago.After admission, she was diagnosed as acute-on-chronic renal failure, respiratory failure, heart failure, severe influenza A (H1N1). The patient was rapidly recovered by the management of high-volume peritoneal dialysis, mechanical ventilation, and medications of Peramivir and Methylprednisolone.Through literature review, case report or cohort study about the treatment of acute kidney disease by high-volume peritoneal dialysis has not been previously reported.This case report suggested that high-volume peritoneal dialysis is able to effectively remove solutes and control volume without causing severe hypoproteinemia and hyperglycemia, which may become an effective renal replacement therapy for children with multi-organ dysfunction syndrome.

Objective: To analyze the clinical characteristics of cases of novel coronavirus pneumonia and a preliminary study to explore the relationship between different clinical classification and liver damage. Methods: Consecutively confirmed novel coronavirus infection cases admitted to seven designated hospitals during January 23, 2020 to February 8, 2020 were included. Clinical classification (mild, moderate, severe, and critical) was carried out according to the diagnosis and treatment program of novel coronavirus pneumonia (Trial Fifth Edition) issued by the National Health Commission. The research data were analyzed using SPSS19.0 statistical software. Quantitative data were expressed as median (interquartile range), and qualitative data were expressed as frequency and rate. Results: 32 confirmed cases that met the inclusion criteria were included. 28 cases were of mild or moderate type (87.50%), and four cases (12.50%) of severe or critical type. Four cases (12.5%) were combined with one underlying disease (bronchial asthma, coronary heart disease, malignant tumor, chronic kidney disease), and one case (3.13%) was simultaneously combined with high blood pressure and malignant tumor. The results of laboratory examination showed that the alanine aminotransferase (ALT), aspartate aminotransferase (AST), albumin (ALB), and total bilirubin (TBil) for entire cohort were 26.98 (16.88 ~ 46.09) U/L and 24.75 (18.71 ~ 31.79) U/L, 39.00 (36.20 ~ 44.20) g/L and 16.40 (11.34- ~ 21.15) mmol/L, respectively. ALT, AST, ALB and TBil of the mild or moderate subgroups were 22.75 (16.31- ~ 37.25) U/L, 23.63 (18.71 ~ 26.50) U/L, 39.70 (36.50 ~ 46.10) g/L, and 15.95 (11.34 ~ 20.83) mmol/L, respectively. ALT, AST, ALB and TBil of the severe or critical subgroups were 60.25 (40.88 ~ 68.90) U/L, 37.00 (20.88 ~ 64.45) U/L, 35.75 (28.68 ~ 42.00) g/L, and 20.50 (11.28 ~ 25.00) mmol/L, respectively. Conclusion The results of this multicenter retrospective study suggests that novel coronavirus pneumonia combined with liver damage is more likely to be caused by adverse drug reactions and systemic inflammation in severe patients receiving medical treatment. Therefore, liver function monitoring and evaluation should be strengthened during the treatment of such patients.

Objective:To investigate the risk factors, severity of symptoms, acute exacerbations, and pulmonary function in women with chronic obstructive pulmonary disease (COPD).Methods:A total of 4 204 COPD patients, including 533 female COPD patients and 3 671 male COPD patients, were investigated from January 2017 to December 2019 in Second Xiangya Hospital of Central South University, Hunan Prevention and Treatment Institute for Occupational Disease, affiliated Hospital of Guilin Medical College and Guilin Second People's hospital. The risk factors, severity of symptoms, risk of acute exacerbation and clinical characteristics of pulmonary function in patients with COPD were comprehensively analyzed.Results:There was no statistical difference in age between male and female COPD patients ( P>0.05). There were statistically significant differences in smoking history, occupational exposure history and biofuel exposure history ( P<0.001), among which smoking history and occupational exposure history were significantly higher in males than in females ( P<0.001), and exposure history of biofuels was significantly higher in females than in males ( P<0.001). The COPD assessment test (CAT) score of male and female patients was statistically different ( P<0.05), and the mean CAT score of female patients was higher than that of male patients. The modified medical research council dyspnea scale (mMRC) grading results of male and female patients were statistically different ( P<0.05), and the mMRC grading of female patients was higher than that of male patients. There was no statistical difference in the risk of acute exacerbation between male and female patients ( P>0.05). There were statistically significant differences between male and female patients in first second exertional volume as a percentage of predicted value (FEV 1%) and forced expiratory volume in one second/forced vital capacity (FEV 1/FVC) mean value ( P<0.001), and FEV 1% predicted value and FEV 1/FVC of female patients were better than that of male patients. Conclusions:The risk factors, symptom severity and pulmonary function of female patients with COPD are different from those of male patients, providing reference for the individualized treatment of female patients with COPD.
