AIM: To investigate the clinical efficacy of pars plana vitrectomy(PPV)combined with fovea-sparing internal limiting membrane(ILM)peeling and silicone oil(SO)tamponade for treating pathological myopic foveoschisis(PMF).METHODS:This study is a retrospective observational analysis of 10 cases(10 eyes)diagnosed with PMF that underwent PPV with fovea-sparing ILM peeling and SO tamponade between January 2023 and November 2024. The best-corrected visual acuity(BCVA), central foveal thickness(CFT), foveoschisis(FS), and the detachment and reattachment of FS and macular fovea were assessed preoperatively and at 1 wk, 1 and 3 mo postoperatively.RESULTS:Among the 10 cases of PMF patients(10 eyes), the complete reattachment rate was 30%(3 eyes), while partial reattachment was observed in 70%(7 eyes). At 3 mo postoperatively, BCVA(LogMAR)was significantly improved to 0.957±0.393 compared with 1.432±0.509 before surgery(P<0.05), and both CFT(437.9±180.4 vs. 207.5±76.1 μm)and FS(686.5±172.2 vs. 290.7±86.6 μm)showed significant decreases(P<0.05). No complications such as macular hole, retinal detachment, silicone oil emulsification, or endophthalmitis were observed during the surgery or throughout the follow-up period.CONCLUSION:PPV with SO tamponade and fovea-sparing ILM peeling has been demonstrated to facilitate both visual acuity improvement and anatomical reattachment in cases of PMF.

This study aims to systematically review and evaluate the quality of clinical research on the treatment of adenomyosis(AM) with traditional Chinese medicine(TCM) in recent ten years, using evidence graphs. Computer searches were conducted on eight Chinese and English databases, commonly used guideline databases, and guideline-related websites, covering the period from January 1, 2014, to October 1, 2024. Two researchers independently screened, extracted information, and evaluated the quality of the evidence. The distribution and quality of the clinical research evidence were presented using both text and charts. A total of 565 articles were included in the study, comprising 523 intervention studies, 23 observational studies, 18 systematic reviews/Meta-analysis, and 1 guideline. The overall publication volume has shown a downward trend in past two years. The sample sizes of the intervention and observational studies primarily focused on 60 to 120 cases. The intervention schemes mainly involved multi-therapy combinations, including 33 classic prescriptions and 25 Chinese patent medicines. Among these, 48 studies related to 17 classic prescriptions and 45 studies related to 10 types of Chinese patent medicines involved TCM syndrome types. Randomized controlled trial(RCT) tended to focus on overall clinical efficacy and the degree of dysmenorrhea as key outcome measures. Methodological quality issues were found in 97 RCTs related to TCM decoctions and 131 RCTs related to Chinese patent medicines, primarily involving unclear explanations of some information. The AMSTAR scores for the 18 systematic reviews/Meta-analysis ranged from 1 to 8 points, with 16 studies suggesting "evidence of potential therapeutic efficacy". The recommended level for the one included guideline was B-level. TCM shows significant advantages in treating AM. Future clinical research should further standardize study designs, reference relevant reporting guidelines, improve the quality of clinical research, generate higher-level evidence-based results, and promote the high-quality development of clinical research on TCM for treating AM.

OBJECTIVES: To analyze the clinical characteristics of diffuse panbronchiolitis (DPB) in children and to enhance the clinical diagnosis and treatment of this disease. METHODS: A retrospective analysis was conducted on the clinical data of 6 children diagnosed with DPB who were hospitalized at The First Affiliated Hospital of Guangzhou Medical University from January 2011 to December 2019. RESULTS: Among the 6 patients, there were 2 males and 4 females; the age at diagnosis ranged from 7 to 12 years. All patients presented with cough, sputum production, and exertional dyspnea, and all had a history of sinusitis. Two cases showed positive serum cold agglutinin tests, and 5 cases exhibited pathological changes consistent with chronic bronchiolitis. High-resolution chest CT in all patients revealed centrilobular nodules diffusely distributed throughout both lungs with a tree-in-bud appearance. Five patients received low-dose azithromycin maintenance therapy, but 3 showed inadequate treatment response. After empirical anti-tuberculosis treatment, non-tuberculous Mycobacteria were found in the bronchoalveolar lavage fluid. Follow-up over 2 years showed 1 case cured, 3 cases significantly improved, and 2 cases partially improved. CONCLUSIONS The clinical presentation of DPB is non-specific and can easily lead to misdiagnosis. In cases where DPB is clinically diagnosed but does not show improvement with low-dose azithromycin treatment, special infections should be considered.

Objective To explore the clinical efficacy of focal external application of Xiaoyu Ointment(mainly composed of wine-processed Rhei Radix et Rhizoma,Taraxaci Herba,Lonicerae Japonicae Flos,Paeoniae Radix Rubra,Curcumae Longae Rhizoma,vinegar-processed Cyperi Rhizoma,Gardeniae Fructus,Angelicae Dahuricae Radix,Angelicae Sinensis Radix,Menthae Haplocalycis Herba,and Notopterygii Rhizoma et Radix)combined with manipulations for relieving swelling on hydro-acupoints of Yinlingquan(SP9),Chize(LU5),Quchi(LI11)and Ashi points around the injury site for the treatment of acute soft tissue injury.Methods A total of 136 patients with acute soft tissue injury were randomly divided into treatment group and control group,with 68 cases in each group.The control group was treated with topical application of Loxoprofen Sodium Gel,and the treatment group was treated with topical application of Xiaoyu Ointment combined with manipulations for relieving swelling on hydro-acupoints.Five days constituted a course of treatment,and the treatment lasted for 2 courses.The changes of visual analogue scale(VAS)score of pain degree,scores of primary symptoms of degree of swelling,degree of activity limitation and pain duration,and the overall scores of traditional Chinese medicine(TCM)syndromes in the two groups were observed before and after treatment.After treatment,the clinical efficacy and safety of the two groups were evaluated.Results(1)After 2 courses of treatment,the total effective rate of the treatment group was 94.12%(64/68)and that of the control group was 91.18%(62/68).There was no significant difference of the total effective rate(by chi-square test)between the two groups(P＞0.05),but the overall efficacy of the treatment group(tested by rank sum test)was significantly superior to that of the control group(P＜0.05).(2)After treatment,the VAS scores of pain degree in the two groups were significantly lower than those before treatment(P＜0.01),and the decrease in the treatment group was significantly superior to that in the control group,the difference being significant(P＜0.01).(3)After treatment,the scores of degree of swelling,degree of activity limitation and pain duration in the two groups were significantly decreased when compared with those before treatment(P＜0.01),and the decrease in the treatment group was superior to that in the control group,the differences being significant(P＜0.05 or P＜0.01).(4)After treatment,the overall scores of TCM syndromes in the two groups were significantly decreased when compared with those before treatment(P＜0.01),but there was no significant difference between the two groups after treatment(P＞0.05).(5)During the treatment period,there was no obvious adverse reaction occurring in the treatment group.In the control group,2 patients had skin flushing and itching in the medicated region,which disappeared after drug withdrawal.Conclusion Topical application of Xiaoyu Ointment combined with manipulations for relieving swelling on hydro-acupoints is effective on alleviating swelling,relieving pain and improving joint motion of range during the treatment of acute soft tissue injury.

Objective:Cardiac arrest (CA) represents a significant public health challenge, posing a substantial threat to individual health and survival. To enhance the survival rates of patients experiencing out-of-hospital cardiac arrest (OHCA), Baoan District in Shenzhen City has undertaken exploratory initiatives and practical interventions, yielding promising preliminary outcomes.Methods:1.Innovate emergency medical services by developing a "four-circle integration" system that connects to the hospital. This system encompasses the social emergency medical system, the out-of-hospital emergency medical system, the in-hospital emergency medical service system, and the intensive care treatment system. 2.Develop a comprehensive model for the construction of a social emergency medical training system, characterized by party leadership, government oversight, departmental coordination, professional guidance, technological support, and community involvement, termed the "Baonan Model." Additionally, establish evaluation criteria to assess the effectiveness of the social emergency medical training system in Baonan District; 3. Develop a cardiac arrest registration system and a social emergency medical training management system for Baonan District; 4. Enhance the proficiency in treatment techniques and the quality of cardiopulmonary resuscitation among emergency medical professionals; 5. Strengthen and advance the development of a "five-minute social rescue network" to address the critical "emergency window period." .Result:In Baonan District, 9.18% of the public is trained in emergency medical skills. The bystander CPR rate for OHCA is 26.11%, AED use is at 4.78%, the 30-day survival rate is 6.31%, and the discharge survival rate is 4.44%.Conclusion:The implementation of the aforementioned measures can substantially enhance the survival rate of patients experiencing OHCA at the time of discharge.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

The abuse of novel phenylcyclohexylpyridine drugs poses a significant threat to societal safety. The novel psychoactive substance 2-methyl-deschloroketamine (2-MDCK), belonging to the phenylcyclohexylpyridine class, has recently surfaced as a new compound. However, there is a lack of understanding regarding its metabolic pathways and the identification of suitable biomarkers. In this study, a human liver microsomal model was established, and ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) technology was applied to investigate the in vitro metabolism and products of 2-MDCK. The results indicate that 2-MDCK undergoes various metabolic reactions, including dehydrogenation, deamination, hydroxylation, and demethylation, leading to the formation of eight metabolites. By conducting actual testing on hair samples from 2-MDCK abusers, the existence of six metabolites was confirmed. Comparing the metabolic products in the liver microsomal in vitro model, M3.1 and M4.1 were identified as biomarkers for 2-MDCK consumption. Five samples of abusers of 2-methyl-dechloroketamine were provided by the Anti-Drug Brigade of the Hangzhou Public Security Bureau. Negative hair samples were provided by laboratory volunteers, and all samples were obtained with the informed consent of the volunteers. These findings provide a scientific basis for the detection and identification of 2-MDCK and its metabolites, as well as crucial support for the study of the metabolic mechanisms of similar novel psychoactive substances in the phenylcyclohexylpyridine class. This research holds significant importance in addressing the issue of abuse of new psychoactive substances.
