ObjectiveTo systematically investigate the medication rules of chicken-derived medicinals for treating children enuresis in ancient Chinese medical classicals. MethodsThe China Medical Classics V5.0 database was searched to identify formulas and passages containing chicken-derived medicinals for pediatric enuresis. A database was established using Microsoft Excel 2021 to extract information including formulas, therapeutic categories, natures, flavors, channel entry, processing methods, dosage forms, and administration methods. Frequency analysis was performed, while association rule analysis and cluster analysis were conducted using R software. Gephi 0.10.1 software was used for complex network analysis. ResultsA total of 171 records were included, comprising 36 single-herb formulas and 135 compound formulas, sourced from 64 classical medical monographs. The identified chicken-derived medicinals included jichang (Intestinum Galli), jineijin (Endothelium Corneum Gigeriae Galli), jigan (Gallina Hepar), jishibai (Faeces Galli Albi), jisu (Ingluvies Galli), jiheling (Pluma Alae Galli), and jiweimao (Chicken tail feathers). The top three frequently used single herbs were jichang (17 times), jineijin (8 times), and jiheling (5 times). Among compound prescriptions, the three most frequently recorded formulas were Jineijin Powder (鸡内金散, 43 times), Jichang Powder (鸡肠散, 25 times), and Guigan Pills (桂肝丸, 24 times), with jineijin, jichang, and jigan being the predominant chicken-derived medicinals. When converting the daily dosage of chicken-derived medicines into modern dosage units, the dose ranged from 0.53 g to 33.57 g for jineijin, with 4.48 g being the most frequently used dose, and from 0.25 g to 30.00 g for jichang, with 17.90 g being the most frequently used dose. Chicken-derived medicinals were mostly used after processing, commonly employing burning (68 times), roasting/ stir-baking (37 times), and calcining (24 times) to preserve properties. Powders (117 times), pills (45 times), and decoctions (9 times) were the principal dosage forms, and administration with wine (70 times) was the most common method. The most frequently used herbal pair was jineijin and roucongrong (Herba Cistanches), while the core prescription combinations were Tusizi Powder (菟丝子散), Yangshi Jichang Powder (杨氏鸡肠散), and Rongxiang Pill (茸香丸). ConclusionChicken-derived medicinals , such as jichang and jineijin, are commonly processed by burning or roasting before use in the treatment of enuresis. They are often combined with longgu (Fossilia Ossis Mastodi), muli (Concha Ostreae), sangpiaoxiao (Oötheca Mantidis), roucongrong and rougui (Cortex Cinnamomi) to warm and tonify the kidney qi, arrest enuresis and emission with astringents. Pills and powders are the predominant dosage forms and are commonly administered before meals with wine or salted water.

ObjectiveTo investigate the potential mechanism of Liangxue Tuizi Formula (凉血退紫方, LXTZF) in treating Henoch-Schönlein Purpura (HSP) by examining its regulatory effect on neutrophil extracellular trap (NETs) dysregulation via the rapidly accelerated fibrosarcoma kinase (RAF)/mitogen-activated protein kinase (MEK)/extracellular signal-regulated kinase (ERK) signaling pathway. MethodsSeventy Wistar rats were randomly allocated into a blank control group (n=14) and a modeling group (n=56). Rats in the modelling group underwent an eight-week modelling period to establish HSP rat models with blood-heat syndrome via modified ovalbumin (OVA) induction method combined with oral administration of heat-property Chinese herbal medicine. Fifty successfully modeled rats were subsequently randomly divided into five groups (n=10 per group), model group, compound glycyrrhizin group, LXTZF group, RAF inhibitor group, and LXTZF + RAF agonist group. Additionally, 10 rats were selected from the original blank control group for the final experiment. From the 11th week of modelling, rats in the blank control group and the model group received 1 ml/(100 g·d) ultrapure water via oral administration, in addition to 0.5 ml/(kg·d) 0.9% sodium chloride solution via intraperitoneal injection. The LXTZF group and the compound glycyrrhizin group received 7.5 g/(kg·d) LXTZF granule suspension via gavage, 13.5 mg/(kg·d) compound glycyrrhizin suspension via gavage, respectively. The RAF inhibitor group received 1 mg/(kg·d) GW5074 suspension via intraperitoneal injection and ultrapure water via oral administration; the LXTZF + RAF agonist group received 7.5 g/(kg·d) LXTZF granule suspension via gavage and 1 mg/(kg·d) paclitaxel suspension via intraperitoneal injection. All administrations were performed once daily for 4 weeks. After intervention, skin tissue histopathology was examined by hematoxylin and eosin (H&E) staining, immunoglobulin A (IgA) deposition was assessed via immunofluorescence, serum levels of neutrophil elastase (NE), tumor necrosis factor-α (TNF-α), and vascular cell adhesion molecule-1 (VCAM-1) were measured using enzyme-linked immunosorbent assay (ELISA), serum myeloperoxidase (MPO) level was determined by a colorimetric assay; the mRNA expression levels of RAF, MEK, and ERK in skin tissue were detected by real-time quantitative polymerase chain reaction (RT-qPCR); and the protein expression of RAF, MEK, ERK, as well as phosphorylated MEK (p-MEK) and phosphorylated ERK (p-ERK), were analyzed by Western Blot. ResultsSkin tissue in the blank control group rats remained normal, whereas the model group exhibited neutrophil infiltration and haemorrhage with red blood cell rupture. In all drug intervention groups, neutrophil infiltration and haemorrhagic exudation reduced markedly, with LXTZF group demonstrating the most pronounced improvement. Compared with the blank control group, rats in the model group exhibited enhanced IgA fluorescence intensity in skin tissue, elevated serum levels of NE, MPO, TNF-α and VCAM-1, increased mRNA expression of RAF, MEK, ERK1 and ERK2, as well as heightened RAF protein levels and p-MEK/MEK and p-ERK/ERK ratios (P<0.05). Compared with the model group, the drug intervention groups exhibited reduced IgA fluorescence intensity in skin tissue, along with decreased serum levels of NE, MPO, TNF-α, and VCAM-1 (P<0.05). In LXTZF group and RAF inhibition groups, reduced mRNA expression of RAF, MEK, ERK1, and ERK2 was observed in rat skin tissue, alongside decreased RAF protein levels and reduced p-MEK/MEK and p-ERK/ERK ratios (P<0.05). Compared with LXTZF + RAF agonist group, the compound glycyrrhizin group, LXTZF group, and RAF inhibitior group exhibited reduced IgA fluorescence intensity in skin tissue, decreased serum NE, MPO, TNF-α, and VCAM-1 levels, and decreased MEK mRNA expression and p-MEK/MEK ratio (P<0.05). ConclusionThe potential mechanism by which LXTZF treats Henoch-Schönlein purpura with blood heat syndrome may involve blocking the RAF/MEK/ERK signaling pathway in skin tissue, and suppressing excessive formation of NETs, thereby reducing IgA deposition in dermal microvessels and attenuating systemic inflammatory responses.

Schizophrenia is a common, severe, and complex psychiatric disorder worldwide. Genetic factors account for around 80% of the etiology of schizophrenia, yet objective diagnostic biomarkers remain lacking. This article reports two cases of female monozygotic twins diagnosed with schizophrenia, exhibiting a balanced translocation between 22q11.2 and 4p15.3. Reviewing the literature, we analyze and discuss the correlation between chromosomal balanced translocation regions and the pathogenesis of mental disorders. This aims to encourage psychiatrists to consider new perspectives on the diagnosis of schizophrenia.

BACKGROUND:The asymmetrical biomechanical environment of adolescent idiopathic scoliosis can lead to further wedge deformation of the vertebral body,which may affect cardiopulmonary function and compress nerves in severe cases.Adolescent idiopathic scoliosis with different degrees of scoliosis should be treated with exercise,bracing,and surgery.However,the mechanical mechanism of selecting an orthopedic approach remains unclear due to the individual variability of patients.OBJECTIVE:To investigate the biomechanical mechanism of different orthopedic modalities for the treatment of adolescent idiopathic scoliosis to provide a basis for clinical selection of treatment modalities based on the spine model of adolescent idiopathic scoliosis patients.METHODS:Based on the CT images of an adolescent idiopathic scoliosis patient,a scoliosis model(C7-L5)was reconstructed in Mimics software in three dimensions,and lateral thrust force was applied at the T8/T9 thorax and vertical distraction force was applied over the C7 vertebra with the magnitude of 20,40,60,80,100,and 120 N.The intervertebral disc stress and vertebral displacement in concave and convex sides,and Cobb angle of the spine were analyzed under two orthopedic modalities.RESULTS AND CONCLUSION:(1)With lateral thrust,there was no significant change in the C7T1-T7T8 intervertebral disc.The concave and convex stress of T7T8-L4L5 segment decreased first and then increased with the increase of lateral thrust force.The correction effect of lateral thrust on the segment near T8T9 was obvious and weakened with the extension of the segment to the cephalic and caudal ends.At 120 N of lateral thrust,the thoracic Cobb angle changed from 53.2° to 32.5° and the lumbar Cobb angle changed from 50.2° to 43.9°.(2)With the vertical distraction,the thoracic intervertebral disc stresses first decreased and then increased,and all the lumbar disc stresses decreased.The C7 displacement was the most obvious,and the correction effect gradually diminished with the segment extended to the caudal end.At a vertical distraction force of 120 N,the thoracic Cobb angle changed from 53.2° to 39.4° and the lumbar Cobb angle changed from 50.2° to 47.6°.(3)It is concluded that both orthopedic modalities provide improvement in the degree of scoliosis,with the thoracic correction being greater than the lumbar correction.Also,the asymmetric stress distribution on the concave and convex sides is improved,which contributes to normal bone growth.A vertical distraction approach is appropriate for larger Cobb angles,and a lateral thrust approach is appropriate for smaller Cobb angles.The results of this study help to understand the mechanism of spinal orthosis and provide a theoretical basis for the choice of orthopedic approach.

Objective:To explore the relationship between serum urea nitrogen to creatinine ratio (UCR) and cardiac function in elderly patients with severe pneumonia.Methods:A prospective selection of 100 elderly patients with severe pneumonia admitted to Group Wanbei General Hospital of Wanbei Coal Power from May 2020 to April 2023 was conducted as the case group, and an additional 50 patients who underwent health examinations in the hospital during the same period were selected as the control group. Serum urea nitrogen (BUN), creatinine (Cr), UCR value, myocardial injury indexes: cardiac troponin I (cTnI), N-terminal pro-brain natriuretic peptide (NT-ProBNP), creatine kinase (CK), creatine kinase isoenzyme MB (CK-MB), and cardiac function indexes: left ventricular ejection fraction (LVEF), cardiac output (CO), stroke volume (SV) and cardiac output index (CI) were detected in the two groups. The patients in the case group were divided into two subgroups based on the occurrence of heart failure during hospitalization: the heart failure subgroup and the normal heart function subgroup. The serum UCR, myocardial injury and cardiac function indexes were compared between the case group and the control group. The general data, myocardial injury and cardiac function indexes were compared between the heart failure group and the normal heart function group. The relationship between serum UCR and cardiac function in patients with severe pneumonia was analyzed by bivariate Pearson correlation. Logistic regression model was used to analyze the influencing factors of cardiac dysfunction in patients with severe pneumonia, and using receiver operating characteristic (ROC) curve to analyze the value of serum UCR in predicting cardiac dysfunction in patients with severe pneumonia.Results:The values of BUN, UCR, cTnI, NT-ProBNP, CK and CK-MB in the case group were higher than those in the control group: (8.72 ± 1.14) μmol/L vs. (6.41 ± 0.76) μmol/L, 125.00 ± 19.75 vs. 86.12 ± 12.02, 0.04 (0.03, 0.05) μg/L vs. 0.04 (0.03, 0.05) μg/L, (185.49 ± 20.59) ng/L vs. (147.76 ± 20.85) ng/L, (104.78 ± 14.98) U/L vs. (99.33 ± 15.07) U/L, (31.59 ± 6.23) U/L vs. (29.13 ± 5.76) U/L. The values of Cr, LVEF, CO, SV and CI in the observation group were lower than those in the control group: (70.22 ± 5.76) μmol/L vs. (74.75 ± 5.12) μmol/L, (59.72 ± 2.41)% vs. (61.78 ± 2.16)%, (3.93 ± 0.43) L/min vs. (4.53 ± 0.62) L/min, (59.82 ± 6.12) ml vs. (62.23 ± 7.22) ml, (2.95 ± 0.30) L/(min·m 2) vs. (3.06 ± 0.33) L/(min·m 2), with a statistical significant difference ( P<0.05). In the case group, 21 patients had heart failure during hospitalization, accounting for 21.00%. The pneumonia severity index score on admission in the heart failure subgroup was higher than that in the normal heart function subgroup: (172.76 ± 9.18) points vs. (168.24 ± 8.81) points. The serum BUN and UCR levels were higher than those in the normal heart function subgroup: (9.51 ± 0.79) mmol/L vs. (8.51 ± 1.13) mmol/L, 141.62 ± 9.89 vs. 120.59 ± 19.39. The serum Cr level was lower than that in the normal heart function subgroup: (67.26 ± 5.34) μmol/L vs. (71.00 ± 5.65) μmol/L, with a significant statistical difference ( P<0.05). There was no significant statistical difference in other data between the two subgroups ( P>0.05). The bivariate Pearson correlation analysis showed that serum UCR was positively correlated with cardiac function indicators cTnI, NT-ProBNP, CK and CK-MB levels in severe pneumonia ( r = 0.40, 0.27, 0.32 and 0.33; P<0.05), and negatively correlated with LVEF, CO, SV and CI levels ( r = - 0.37, - 0.21, - 0.25 and - 0.21; P<0.05). Univariate and multivariate Logistic regression analysis showed that the occurrence of cardiac dysfunction in elderly patients with severe pneumonia may be related to the pneumonia severity index score on admission and the abnormal expression of serum BUN, UCR and Cr levels ( P<0.05). ROC curve analysis found that the area under the curve for predicting the occurrence of cardiac dysfunction during hospitalization in severe pneumonia patients with serum UCR on admission was 0.85 (95% CI 0.77 to 0.92), which had certain predictive value. Conclusions:Elderly patients with severe pneumonia are accompanied by a certain degree of elevated serum UCR levels, and the higher the serum UCR level, the more severe the cardiac function damage and the greater the risk of cardiac dysfunction.

Objective:To investigate the conversion of stromal vascular fraction (SVF) in the microenvironment of radiation-induced skin injuries to provide guidance for clinical applications.Methods:Based on a random number table, C57BL/6N mice were categorized into four groups: the blank control, negative control, acute injury, and chronic injury groups, with each group containing 25 mice. The backs of mice in the blank control, acute injury, and chronic injury groups were exposed to 15 Gy X-ray irradiation. Then, the mice in the negative control, acute injury, and chronic injury groups were injected subcutaneously with the SVF derived from B6/G-R mice. The survival of these mice was observed 1, 3, 7, 14, and 21 d after the injection through fluorescence tracing and in vivo imaging. Accordingly, the clinical SVF injection regimens were optimized based on the experimental result of mice. Finally, local SVF injection was performed on different frequencies for patients in different wound conditions, with the efficacy being observed. Results:The fluorescence of SVF was observed from the tissue slices of the acute injury, chronic injury, and negative control groups 14 d post-injection. The result showed that the fluorescence intensity of SVF 1, 3, and 7 d post-injection was in the order of the negative control group > the acute injury group > the chronic injury group. The acute injury group ranked at the top and the chronic injury group remained at the bottom 14 d after the injection. The fluorescence of SVF in each group was barely detected 21 d after the injection. Compared to the negative control group, the acute injury group exhibited statistical differences only 14 d post-injection ( t = 4.11, P < 0.05), while the chronic injury group displayed statistical differences 1, 3, 7, and 14 d after the injection ( t = 3.88-5.74, P < 0.05). Furthermore, the acute injury group exhibited significantly higher fluorescence intensity of SVF than the chronic injury group ( t = 4.73-8.38, P < 0.05). The half-life of SVF for the negative control, acute injury, and chronic injury groups was 6.336, 6.014, and 2.163 d, respectively. As indicated by the application of SVF transplantation based on traditional surgical protocols in the clinical trial, SVF can significantly promote wound repair, with earlier SVF transplantation being more beneficial for wound healing. Conclusions:The conversion of SVF differs in the microenvironments of acute and chronic radiation-induced skin injuries. This can serve as an essential guide for the administration timing and injection frequency of SVF in clinical applications.

Objective :
To investigate the epidemiological characteristics of severe fever with thrombocytopenia syndrome (SFTS) in Dongyang City, Zhejiang Province from 2017 to 2022, so as to provide insights into SFTS prevention and control.
Methods:
Data pertaining to patients with SFTS in Dongyang City from 2017 to 2022 were collected from Notifiable Infectious Disease Reporting System of Chinese Disease Prevention and Control Information System. The epidemiological and clinical characteristics of patients with SFTS were descriptively analyzed, and the trends in incidence of SFTS was evaluated using annual percent change (APC).
Results:
A total of 32 SFTS cases were reported in Dongyang City from 2017 to 2022, with mean annual incidence of 0.63/105, and 8 cases died, with a fatality rate of 25.00%. The incidence of SFTS appeared a tendency towards a rise from 2017 to 2022 (APC=40.697%, P<0.05). The male to female ratio of SFTS cases was 0.78∶1, and farmer was the predominant occupation (31 cases, 96.88%). SFTS predominantly occurred among individuals at ages of 51 to 69 years (20 cases, 62.50%), and the incidence peaked during the period between March and May and between July and August (28 cases, 87.50%). SFTS cases were reported in 11 out of the 18 townships (streets) in Dongyang City, with the highest number found in Zuocun Township (8 cases, 28.13%), and had the lowest platelet count of (41.46±5.19)×109 platelets/L, with the lowest count of (3.00 to 67.00) ×109 platelets/L. All the SFTS cases had a history of mountain forest and farmland activities 2 weeks prior to onset of the disease, and 5 cases (15.63%) had a history of tick bites.
Conclusions
The incidence of SFTS appeared a tendency towards a rise in Dongyang City from 2017 to 2022, and SFTS was highly prevalent in spring and summer, with high incidence among farmers. Intensified health education of SFTS is recommended among residents in high-incidence areas.
