ObjectiveTo investigate the current status of emergency management for severe mental disorders in Shanghai, and to provide countermeasures and suggestions for the establishment of a sound emergency management system for severe mental disorders and the enhancement of emergency management capability. MethodsA questionnaire survey and qualitative interviews were used to conduct an investigation into the emergency management in 17 district-level mental illness prevention and control institutions in Shanghai, which includes the basic situation of emergency management for severe mental disorders, the construction of emergency response teams and personnel, emergency preparedness drills and training, emergency management plans and rules and regulations, and problems encountered in emergency management. ResultsIn terms of emergency management mechanism and basic situation, resources such as personnel allocation, security funds and green channel were well equipped in each district-level mental illness prevention and control institution in Shanghai. However, the equipment of some hardware facilities was still insufficient to some extent. Therefore, further improvement on the emergency management mechanism for severe mental disorders was needed. With regard to the construction of emergency team and personnel allocation, the majority were those aged between 35‒<45 years old, with a bachelor’s degree, and more than 10 years of working experience. For example, 90.27% staff in district-level mental illness prevention and control institution had a bachelor’s degree or above, which was higher than that among the staff in community-level (73.60%); staff majored in clinical medicine in district-level institution accounted for the proportion at 52.71%, higher than that among the staff in community-level (28.86%); 57.24% staff in district-level institution had an intermediate professional title, higher than that among the staff in community-level (42.28%); and 69.90% staff in district-level institution had more than 10 years of working experience, higher than that among the staff in community-level (43.62%). In the aspect of emergency drills and training, all district-level mental illness prevention and control institutions in Shanghai had a high demand for emergency training, and the weak aspects mainly focused on lack of emergency service protocols, skills of addressing technical challenges, and construction of effectiveness evaluation system. Moreover, the teaching methods were primarily centered on case analysis, simulation drills, interactive discussions, and so forth. Concerning emergency management plans and rules and regulations, all districts in Shanghai had relatively established well-developed systems for emergency response plans, emergency response leadership groups, and emergency response operational task forces for severe mental disorders. About half of the institutions had established other rules and regulations related to emergency management of severe mental disorders in addition to emergency plans. ConclusionShanghai has initially established an emergency management system for severe mental disorders, but it is still fragile in specialized training for emergency management of severe mental disorders, construction of emergency management mechanisms, and the building-up of grassroots emergency teams. Further priorities should include strengthening emergency management training, enhancing the construction of emergency management personnel teams, and gradually establishing a more comprehensive and integrated emergency management mechanism for severe mental disorders.

Blood heat syndrome, one of the main subtypes of blood syndrome in traditional Chinese medicine(TCM), is mainly diagnosed by bleeding and heat manifestations and treated by the blood-cooling method. The biological essence of blood heat syndrome has not been elucidated yet, and there is a lack of systematic research on the potential mechanisms underlying the blood-cooling method. The biological essence of blood heat syndrome is closely related to abnormal immune response, oxidative stress, coagulation dysfunction, endocrine disorders, abnormalities in energy metabolism and so on. Blood heat syndrome is common in autoimmune skin diseases( such as systemic lupus erythematosus, psoriasis, and purpura), central hyperthermia, infectious diseases( such as infectious mononucleosis and COVID-19), and hemorrhagic diseases in gynecology. As the primary clinical therapy for blood heat syndrome, blood-cooling TCM is usually combined with the TCM with effects of activating blood and resolving stasis, nourishing Yin,and extinguishing wind to play the role of cooling blood. The mechanisms of above therapies may be attributed to reducing inflammation, inhibiting oxidative stress, restoring the balance of blood coagulation and metabolism, regulating the secretion of sex hormones, and alleviating allergic reactions. This article systematically explores the biological essence of blood heat syndrome and elucidates the targets and underlying mechanism of the blood-cooling method, laying a scientific foundation for the clinical application of TCM in the prevention and treatment of diseases associated with blood heat syndrome.

OBJECTIVE: To identify the gene mutation types of 4 suspected β-thalassemia patients in Yunnan Province, and to analyze the genotypes and hematological phenotypes. METHODS: Whole genome sequencing was performed on the samples of 4 suspected β-thalassemia patients from the Dai ethnic group in a thalassemia endemic area of Yunnan Province, whose hematological phenotypes were not consistent with the results of common thalassemia gene mutations. The mutations of β-globin gene clusters were confirmed by polymerase chain reaction (PCR) and Sanger DNA sequencing technology. RESULTS: The 3.5 kb deletion in β-globin gene cluster (NC_000011.10: g. 5224302-5227791del3490bp) was detected in 4 patients' samples, of which 1 case was also detected with HbE mutation and 1 case with CD17 mutation. These 2 patients displayed moderate anemia phenotype, while the two patients with only the 3.5 kb deletion presented with other mild anemia phenotype. CONCLUSION Heterozygous carriers with rare 3.5 kb deletion of the β-globin gene cluster may develop mild anemia, compound mutations of the 3.5 kb deletion with other mutations may led to intermediate thalasemia with moderate to sever anemia. In areas with a high incidence of thalassemia, suspected patients should undergo genetic testing to avoid missing or misdiagnosing rare mutations.

BACKGROUND: The atherogenic index of plasma (AIP) has been shown to be positively correlated with cardiovascular disease in previous studies. However, it is unclear whether elderly people with long-term high AIP levels are more likely to develop coronary heart disease (CHD). Therefore, the aim of this study was to investigate the relationship between AIP trajectory and CHD incidence in elderly people. METHODS: 19,194 participants aged ≥ 60 years who had three AIP measurements between 2018 and 2020 were included in this study. AIP was defined as log₁₀ (triglyceride/high-density lipoprotein cholesterol). The group-based trajectory model was used to identify different trajectory patterns of AIP from 2018 to 2020. Cox proportional hazards models were used to estimate the hazard ratio (HR) with 95% CI of CHD events between different trajectory groups from 2020 to 2023. RESULTS: Three different trajectory patterns were identified through group-based trajectory model: the low-level group (n = 7410, mean AIP: -0.25 to -0.17), the medium-level group (n = 9981, mean AIP: 0.02-0.08), and the high-level group (n = 1803, mean AIP: 0.38-0.42). During a mean follow-up of 2.65 years, a total of 1391 participants developed CHD. After adjusting for potential confounders, compared with the participants in the low-level group, the HR with 95% CI of the medium-level group and the high-level group were estimated to be 1.24 (1.10-1.40) and 1.43 (1.19-1.73), respectively. These findings remained consistent in subgroup analyses and sensitivity analyses. CONCLUSIONS There was a significant correlation between persistent high AIP level and increased CHD risk in the elderly. This suggests that monitoring the long-term changes in AIP is helpful to identify individuals at high CHD risk in elderly people.

OBJECTIVE: To evaluate the dynamic changes of glucocorticoid (GC) dose and the feasibility of GC discontinuation in rheumatoid arthritis (RA) patients under the background of Chinese medicine (CM). METHODS: This multicenter retrospective cohort study included 1,196 RA patients enrolled in the China Rheumatoid Arthritis Registry of Patients with Chinese Medicine (CERTAIN) from September 1, 2019 to December 4, 2023, who initiated GC therapy. Participants were divided into the Western medicine (WM) and integrative medicine (IM, combination of CM and WM) groups based on medication regimen. Follow-up was performed at least every 3 months to assess dynamic changes in GC dose. Changes in GC dose were analyzed by generalized estimator equation, the probability of GC discontinuation was assessed using Kaplan-Meier curve, and predictors of GC discontinuation were analyzed by Cox regression. Patients with <12 months of follow-up were excluded for the sensitivity analysis. RESULTS: Among 1,196 patients (85.4% female; median age 56.4 years), 880 (73.6%) received IM. Over a median 12-month follow-up, 34.3% (410 cases) discontinued GC, with significantly higher rates in the IM group (40.8% vs. 16.1% in WM; P<0.05). GC dose declined progressively, with IM patients demonstrating faster reductions (median 3.75 mg vs. 5.00 mg in WM at 12 months; P<0.05). Multivariate Cox analysis identified age <60 years [P<0.001, hazard ratios (HR)=2.142, 95% confidence interval (CI): 1.523-3.012], IM therapy (P=0.001, HR=2.175, 95% CI: 1.369-3.456), baseline GC dose ⩽7.5 mg (P=0.003, HR=1.637, 95% CI: 1.177-2.275), and absence of non-steroidal anti-inflammatory drugs use (P=0.001, HR=2.546, 95% CI: 1.432-4.527) as significant predictors of GC discontinuation. Sensitivity analysis (545 cases) confirmed these findings. CONCLUSIONS RA patients receiving CM face difficulties in following guideline-recommended GC discontinuation protocols. IM can promote GC discontinuation and is a promising strategy to reduce GC dependency in RA management. (Trial registration: ClinicalTrials.gov, No. NCT05219214).

BACKGROUND: A growing body of research is exploring the role of antioxidant and anti-inflammatory dietary supplements in the treatment of osteoarthritis, highlighting an increasing emphasis on non-pharmacological interventions. Although more patients are turning to supplements to manage osteoarthritis, their actual effectiveness remains uncertain. OBJECTIVE: This study aims to provide a comprehensive evaluation of the available evidence concerning the efficacy of various dietary supplements in osteoarthritis treatment. SEARCH STRATEGY: We searched PubMed, Embase, Cochrane Library and Web of Science for studies on the use of various dietary supplements in the treatment of osteoarthritis from the creation of each database until Jan 20, 2025. INCLUSION CRITERIA: (1) Research object: osteoarthritis. (2) Intervention measures: patients in the treatment group received dietary supplements, while the control group received placebos. (3) Research type: randomized controlled trials (RCTs). DATA EXTRACTION AND ANALYSIS: Two researchers independently examined the literature and retrieved data based on predefined criteria. The information gathered included the first author, year of publication, sample size, participant demographics, length of the follow-up period, intervention and control measures, and inclusion indications. RCTs comparing dietary supplements to placebo with the pain and function subscales of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) among patients with osteoarthritis were included. The optimal dietary supplement was identified based on the total ranking by summing the surface under the cumulative ranking curve (SUCRA) of these two scores. Furthermore, the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) was used to confirm the quality of the evidence. RESULTS: Overall, 23 studies covering 21 dietary supplements and involving 2455 participants met the inclusion criteria. In the WOMAC pain score, the SUCRA of passion fruit peel extract was 91% (mean difference [MD]: -9.2; 95% confidence interval [CI]: [-16.0, -2.3]), followed by methylsulfonylmethane (89%), undenatured type II collagen (87%), collagen (84%), and Lanconone (82%). The SUCRA (99%) of passion fruit peel extract (MD: -41.0; 95% CI: [-66.0, -16.0]) ranked first in terms of the WOMAC function score, followed by Lanconone (95%), collagen (86%), ParActin (84%), and Lactobacillus casei strain Shirota (83%). The top three total rankings are passion fruit peel extract (95.0%), Lanconone (88.5%), and collagen (85.0%). However, the GRADE revealed low evidence quality. CONCLUSION Passion fruit peel extract was the best supplement for improving WOMAC pain and function scores in patients with osteoarthritis, followed by Lanconone and collagen. However, further large-scale, well designed RCTs are required to substantiate these promising findings.

Objective To explore a method for assessing the irregular small opacities profusion associated with occupational pneumoconiosis in chest computed tomography (CT). Methods A total of 20 occupational pneumoconiosis patients whose primary manifestation was irregular small opacities on chest digital radiography (DR) were collected as the research subjects using a retrospective study method. Comparative analysis was performed between chest DR and five mm coronal multi-planar reconstruction (MPR) of chest CT images to identify the causes of irregular small opacities. An evaluation method for the profusion of associated images of irregular small opacities in chest CT was established using technique for order preference by similarity to ideal solution-analytic hierarchy process (TOPSIS-AHP), and the results were compared against GBZ 70-2015 Diagnosis of Occupational Pneumoconiosis. Results The abnormal image distribution on the five mm coronal chest CT MPR images of the 20 patients was as follows: three cases of high-density small circular opacities, seven cases of low-density circular small opacities, six cases of diffuse low-density ground-glass opacities (GGO), four cases of reticular opacities, three cases of plate-like GGO, three cases of honeycomb opacities, and four cases of increasing lung texture. The CT values of abnormal images, from high to low were: honeycomb opacities > plate-like GGO > low-density circular small opacities > diffuse low-density GGO (all P<0.05). The consistency test results indicated that the evaluation method for the profusion of associated images of irregular small opacities in chest CT showed high level of agreement with the profusion determination criteria outlined in GBZ 70-2015 Diagnosis of Occupational Pneumoconiosis (Kappa=0.78). Conclusion Irregular small opacities observed on chest DR are formed by the superposition of multiple images of abnormal pulmonary fibrosis in patients with occupational pneumoconiosis. TOPSIS-AHP can be used to establish an evaluation method of the profusion of associated image of irregular small opacity in chest CT.

Objective:To investigate the therapeutic efficacy of modified decoction for dissipating stasis in the epiglottis in the treatment of phlegm-stasis intermingling type chronic tonsillitis and its effects on patients' traditional Chinese medicine (TCM) symptom scores, white blood cell count (WBC), and serum interleukin-3 (IL-3) levels.Methods:A total of 120 patients with phlegm-stasis intermingling type chronic tonsillitis who received treatment at Xi'an Hospital of Traditional Chinese Medicine from January 2022 to October 2023 were selected for this randomized controlled study. The patients were randomly divided into two groups of 60 each using a random number table method. The control group received amoxicillin capsules combined with open-throat sword spray, while the observation group was treated with modified decoction for dissipating stasis in the epiglottis. All patients were treated for 14 days. Clinical efficacy was evaluated in each group. TCM symptom and sign scores, serum T-lymphocyte subgroups, WBC, high-sensitivity C-reactive protein (hs-CRP), and IL-3 levels were compared between the two groups before and after treatment.Results:The total response rate in the observation group was 93.33% (56/60), which was significantly higher than that in the control group [80.00% (48/60), χ2 = 4.62, P < 0.05]. After treatment, the scores for symptoms including dry and astringent pharynx, prolonged soreness, itchy pharynx, cough with white sputum, chest and epigastric congestion, and poor appetite were significantly lower in both groups compared with their baseline scores (all P < 0.001). After treatment, all symptom scores in the observation group were significantly lower than those in the control group ( t = 8.08, 18.01, 13.36, 8.75, 8.57, 9.17, all P < 0.001). The WBC, hs-CRP, and IL-3 levels in the observation group were (8.23 ± 1.44) × 10?/L, (5.62 ± 1.27) mg/L, and (81.36 ± 8.87) ng/L, respectively. These values were significantly lower than those in the control group [(10.05 ± 1.91) × 10?/L, (8.23 ± 1.78) mg/L, (97.43 ± 10.22) ng/L, t = 5.89, 0.95, 9.20, all P < 0.001]. After treatment, the ratios of CD 4+/CD 8+, NK lymphocytes, and CD 4+ levels in each group were significantly higher than their pre-treatment values (all P < 0.001). After treatment, these values in the observation group were significantly higher than those in the control group ( t = 2.30, 6.31, 5.97, 6.60, all P < 0.05). The difference in the incidence of adverse events between the two groups was not statistically significant ( P > 0.05). Conclusion:The treatment of phlegm-stasis intermingling type chronic tonsillitis with a modified decoction for dissipating stasis in the epiglottis can reduce WBC, and hs-CRP and IL-3 levels. It also improves T-lymphocyte subpopulations, alleviates symptoms, and enhances therapeutic efficacy.

Objective To explore the effect of nasal intestinal obstruction catheter placement in the treatment of intestinal obstruction during pregnancy.Methods A total of 92 patients with intestinal obstruction during pregnancy admitted to our hospital from January 2021 to January 2022 were divided into the observation group(46 cases,treated with nasal intestinal obstruction catheter placement)and the control group(46 cases,treated with ordinary nasogastric tube for gastrointestinal decompression)by random number table method.The curative effect,gastrointestinal function and immune function of patients in the two groups were observed,and the maternal and infant outcomes were recorded.Results The total effective rate of patients in the observation group was higher than that in the control group(P<0.05).After treatment,the levels of CD4+T lymphocytes increased in both groups of patients,while the levels of IgG,IgA,IgM,and CD8+T lymphocytes decreased,and those in the observation group were superior to the control group,with statistically significant differences(P<0.05).The recovery time of bowel sounds,anal exhaust time and first defecation time after treatment in the observation group were earlier than those in the control group(P<0.05).A total of 42 patients(91.30% )in the observation group delivered at full term after conservative treatment,with good maternal and infant outcomes;35 patients(76.09% )in the control group recovered and discharged after conservative treatment,there was a statistically significant difference in the recovery and discharge rate between patients of the two groups(P<0.05).Conclusion Nasal intestinal obstruction catheter placement can effectively improve gastrointestinal function of patients with intestinal obstruction during pregnancy,and enhance the immune function and recovery rate.

Objective:To investigate the effect of feeder layer cells expressing interleukin(IL)-21 on the amplification of NK cells in vitro.Methods:The K562 cell line with IL-21 expression on its membrane was constructed by electroporation,and co-cultured with NK cells after inactivation.The proliferation of NK cells was observed.The killing function of the amplified NK cells in vitro was evaluated by the lactate dehydrogenase(LDH)and interferon-γ(IFN-y)release assay.A colorectal cancer xenograft model in NOD/SCID mice was established,and a blank control group,a NK cell group and an amplified NK cell group were set up to detect the tumor killing effect of amplified NK cells in vivo.Results:K562 cells expressing IL-21 on the membrane were successfully constructed by electroporation.After co-culturing with K562 cells expressing IL-21 on the membrane for 17 days,the NK cells increased to 700 times,which showed an enhanced amplification ability compared with control group(P＜0.001).In the tumor cell killing experiment in vitro,there was no significant difference in the killing activity on tumor cells between NK cells and amplified NK cells,and there was also no significant difference in mice in vivo.Conclusion:K562 cells expressing IL-21 on the membrane can significantly increase the amplification ability of NK cells in vitro,but do not affect the killing function of NK cells in vitro and in vivo.It can be used for the subsequent large-scale production of NK cells in vitro.
