ObjectiveTo investigate the possible mechanism of Pibai Yucuo Formula (枇柏愈痤方, PYF) in treating acne from the perspective of skin barrier damage. MethodsThirty-two mice were randomly divided into blank group, model group, minocycline group, and PYF group, with 8 mice in each group. Except for the blank group, mice were induced by intradermal injection of Cutibacterium acnes (C.acnes) combined with topical application of artificial sebum to establish acne model. The blank group and model group received intragastric administration of 0.2 ml of distilled water, while the PYF group received intragastric administration of 22.75 g/(kg·d)of PYF, and the minocycline group received 0.013 g/(kg·d)of minocycline suspension, all once daily for 5 consecutive days. On day 0 and day 6 of the experiment, the body weight of mice in each group was recorded, and the absolute value of the body weight difference during the experiment was calculated. Skin conditions were assessed with multifunctional skin imaging system on the 2nd, 4th and 6th day of the experiment. Skin barrier function indicators including transepidermal water loss (TEWL), and the water content of the stratum corneum and epidermis on day 0, 2, 4 and 6 of the experiment. Optical coherence tomography (OCT) was used to observe stratum corneum and skin thickness on the 1st, 3rd and 5th day of the experiment. Hematoxylin-eosin (HE) staining was performed to observe histopathological changes, while ELISA was used to detect interleukin-17A (IL-17A) levels, and immunofluorescence staining was used to assess skin barrier-related proteins filaggrin (FLG) and loricrin (LOR) levels of skin lesions on day 6 of the experiment. ResultsCompared to the blank group, the model group showed a decrease in body weight on day 6, and an increase in the absolute value of the difference in body weight before and after the experiment (P<0.05). On day 4 and 6, TEWL values increased, while water content in the skin stratum corneum and epidermis decreased (P<0.05), accompanied by elevated IL-17A level and reduced immunofluorescence intensity of FLG and LOR proteins (P<0.05). The model group mice showed papules or pustules at the skin modeling site with progressively worsening desquamation under multifunctional skin imaging system. OCT revealed focal epidermal protrusions, blurred epidermal-dermal boundaries, and disorganized structural layers. HE staining showed significant epidermal hyperkeratosis and incomplete keratinization in the skin, with keratin plug formation in hair follicles and glandular lumens, thickened stratum corneum, hyperplasia of the stratum spinosum, as well as dense dermal inflammatory cell infiltration, and capillary dilation. Compared to the model group, both the minocycline group and the PYF group showed a reduced difference in body weight before and after experiment (P<0.05). On day 4 and 6, the TEWL value decreased, and water content of the skin stratum corneum increased (P<0.05); on day 6, the IL-17A level in the skin lesions decreased and immunofluorescence intensity of FLG and LOR proteins increased (P<0.05). On day 4 and 6, the severity of the skin lesions and range of redness and swelling were lighter than those in the model group, with reverted epidermal thickness, smoother surface and clearer epidermis-dermis boundary. HE staining showed that the degree of skin keratinization was reduced, and the inflammatory infiltration and vascular dilation in the dermis were improved compared to the model group. The PYF group showed better results than the minocycline group in reducing TEWL value on day 4 (P<0.05). ConclusionPYF may improve inflammation and skin barrier damage by downregulating IL-17A levels in lesion tissue and increasing skin barrier-related proteins, which could be one of the potential mechanism of action on acne.

According to traditional Chinese medicine (TCM) theory, impaired spleen transportation function disrupts nutrient distribution, causing metabolic accumulation of lipids that transform into pathogenic phlegm-dampness. These pathological factors disseminate through the San Jiao and obstruct meridian pathways, ultimately forming the pathogenesis described as "all disorders involve phlegm". Phlegm and dampness share common pathogenic origins but manifest distinct clinical manifestations. Dampness, as the precursor, may congeal into phlegm, while existing phlegm accumulation can further exacerbate dampness stagnation, thereby establishing a self-perpetuating pathological cycle. Modern medical research has confirmed that the essence of "phlegm-dampness" syndrome is closely associated with energy metabolism disorders, serving as a common pathological basis for metabolic syndrome, type 2 diabetes mellitus, atherosclerosis, and other major chronic diseases. As a crucial vehicle for medical experimental research, disease-syndrome combination animal models serve as an indispensable means to advance the modernization of TCM. Currently, based on classical theories such as "rich and greasy foods produce phlegm" and "physical coldness combined with cold consumption causes external pathogens to invade the skin and hair, thereby generating internal dampness", researchers primarily employ two paradigms to construct animal models of phlegm-turbidity, dampness obstruction, and phlegm-dampness syndromes: the first involves simulating TCM etiological factors (through methods like dietary irregularities, imblanace between work and rest, and combined internal-external dampness exposure), while the second combines disease with syndrome differentiation (inducing pathological changes through physical, chemical, or biological interventions). Through comprehensive evaluation incorporating macroscopic observation and microscopic index detection, model animals undergo systematic biological and pathological assessment, with further syndrome type verification achieved via the "prescription-based syndrome detection" approach. However, existing models still exhibit significant deficiencies in both the standardization of modeling methodologies and the systematization of evaluation criteria. This paper reviews the strategies for constructing "phlegm-dampness" syndrome animal models and their corresponding evaluation indices, focusing on the pathological correlations among different modeling approaches. The aim is to provide methodological guidance for research on TCM syndromes related to "phlegm-dampness" syndrome and to support the development of TCM therapies for resolving phlegm and eliminating dampness. This study not only contributes to advancing the standardization of TCM syndrome research but also provides crucial technical support for the modernization of TCM.

ObjectiveThis paper aims to investigate the traditional Chinese medicine syndrome types in patients with chronic hepatitis B (CHB) complicated by metabolic dysfunction-associated fatty liver disease (MAFLD) and explore the correlations between these syndrome types and clinical indicators, as well as ocular manifestation characteristics, thereby providing a reference for syndrome differentiation and treatment strategies in traditional Chinese medicine. MethodsGeneral data, information from the four diagnostic methods of traditional Chinese medicine, clinical indicators, and ocular manifestation data were collected from 506 patients with CHB complicated by MAFLD enrolled at the Public Health Clinical Center of Chengdu between June 2024 and December 2024. Cluster analysis, principal component analysis, and complex network models were employed to identify the distribution patterns of traditional Chinese medicine syndromes. Correlations between different syndrome types and clinical indicators, as well as ocular manifestation characteristics, were further analyzed. ResultsThe predominant syndromes identified in patients with CHB complicated by MAFLD were dampness and heat accumulation (51.58%), liver depression with spleen deficiency (31.62%), blood stasis obstructing collaterals (8.89%), and Qi-Yin deficiency (7.91%). No statistically significant differences were found among the four syndrome types in routine blood tests and liver function indicators. However, patients with the dampness and heat accumulation type exhibited significantly higher levels of total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), liver stiffness measurement (LSM), controlled attenuation parameter (CAP), and alpha-fetoprotein (AFP), along with lower levels of high-density lipoprotein cholesterol (HDL-C), compared with those with other syndrome types. Regarding ocular manifestations, the incidence of moon halo signs was significantly higher in patients with the blood stasis obstructing collaterals type than in those with other syndrome types. Additionally, the incidence in scleral zone 3 (corresponding to the large intestine) was higher in patients with the damp and heat accumulation type. ConclusionDampness and heat accumulation is the core syndrome type in patients with CHB complicated by MAFLD, commonly accompanied by spleen deficiency, liver depression, blood stasis, and Yin deficiency. A complex syndrome pattern characterized by a predominance of dampness and heat, along with a mixture of deficiency and excess, is formed. Different traditional Chinese medicine syndrome types are associated with distinct clinical indicators and ocular manifestation characteristics. Among them, patients with the dampness and heat accumulation type exhibit more pronounced metabolic disturbances and liver injury, whereas those with the blood stasis type show a higher incidence of moon halo signs. Abnormalities in scleral zone 3 are also more prevalent in patients with dampness and heat type.

BackgroundAs a high prevalence disorder, schizophrenia has caused significant burden to family and society due to the impairment of occupational and social function. Currently, the dominant vocational training model in China follows a paternalistic, clinician-led decision-making approach. Although it improves patients' social function to some extent, it undermines their autonomy and treatment adherence. Therefore, it is urgently necessary to explore a new intervention method to enhance treatment compliance and social function in patients. ObjectiveTo explore the impact of shared decision-making oriented vocational training on social function in hospitalized schizophrenia patients, so as to provide references for rehabilitation interventions. MethodsA total of 68 patients diagnosed with schizophrenia according to the International Classification of Diseases, tenth edition (ICD-10) criteria were consecutively enrolled from January to June 2024 at The Third People's Hospital of Wenjiang Distric, Chengdu. Participants were randomly allocated into the research group (n=34) and the control group (n=34) using a random number table method. Both groups received routine rehabilitation training, while the research group received shared decision-making oriented vocational training for 12 weeks, 2 times a week for 2 hours each time. Before and at the 4th and 12th week of intervention, two groups were evaluated by General Self-Efficacy Scale (GSES), Stigma Scale for Mental Illness (SSMI), Scale of Social function of Psychosis Inpatients (SSFPI) and Inpatient Psychiatric Rehabilitation Outcome Scale (IPROS). ResultsA total of 63 participants completed the study, with 30 cases in the research group and 33 cases in the control group. Repeated measures ANOVA revealed statistically significant time effects and interaction effects in both groups for GSES, SSMI, SSFPI and IPROS scores (F=20.451, 16.022; 26.193, 12.944; 23.957, 5.023; 11.776, 3.985, P<0.05 or 0.01), while no significant group effects were observed (F=0.188, 0.742, 1.878, 0.474, P>0.05). At the 12th week of intervention, there were statistically significant differences in GSES, SSMI, SSFPI and IPROS scores between the two groups. ConclusionShared decision-making oriented vocational training may help to improve social function in patients with schizophrenia. [Funded by 2023 Chengdu Medical Research Project (number, 2023468)]

ObjectiveTo evaluate the clinical efficacy and safety of Huaban Jiedu Formulation (化斑解毒方, HJF) in treating psoriasis vulgaris with blood-heat syndrome. MethodsA randomized, double-blind, placebo-controlled study was conducted with 60 patients diagnosed with psoriasis vulgaris of blood-heat syndrome. Patients were randomly assigned to either a treatment group or a control group, with 30 cases in each. The treatment group received HJF granules orally, one dose a day, combined with topical Qingshi Zhiyang Ointment (青石止痒软膏), while the control group received placebo granules, one dose a day, combined with the same topical ointment. Both groups were topically treated twice daily of 28 days treatment cours. Psoriasis area and severity index (PASI), visual analogue scale for pruritus (VAS), traditional Chinese medicine (TCM) syndrome scores, dermatology life quality index (DLQI), and psoriasis life stress inventory (PLSI) were assessed before treatment and on day 14 and day 28. Response rates for PASI 50 (≥50% reduction) and PASI 75 (≥75% reduction), as well as overall clinical efficacy, were compared between groups. Serum levels of interleukin-6 (IL-6) and interleukin-17 (IL-17) were measured before and after 28 days of treatment. Adverse reactions during treatment were recorded. ResultsAfter 28 days of treatment, both groups showed significant reductions in PASI total score, lesion area score, erythema, scaling, and infiltration scores, pruritus VAS score, TCM syndrome score, DLQI, PLSI, and serum IL-6 and IL-17 levels (P<0.05). Compared to the control group, the treatment group had significantly greater improvements in PASI total score and erythema score, TCM syndrome score, serum IL-6 and IL-17 levels, and PASI 50 response rate after 28 days (P<0.05). Between-group comparisons of score differences before and after 28-day treatment revealed that the treatment group showed significantly better improvements in PASI total, lesion area score, erythema score, TCM syndrome score, DLQI, PLSI, and inflammatory markers (P<0.05 or P<0.01). The total effective rate on day 14 and day 28 was 40.00% (12/30) and 83.33% (25/30) in the treatment group, versus 6.90% (2/29) and 41.38% (12/29) in the control group, respectively. The clinical efficacy in the treatment group was significantly superior to that in the control group (P<0.05). Mild gastric discomfort occurred in 3 patients in the treatment group and 1 in the control group. ConclusionHJF can effectively improve skin lesions and TCM symptoms relieve pruritus, enhance quality of life, and reduce inflammatory markers IL-6 and IL-17, in patients with blood-heat syndrome of psoriasis vulgaris, with a good safety profile.

Objective To investigate the levels and influencing factors for eye lens dose of interventional radiology workers, and to provide a basis for reasonable and scientific radiation protection. Methods Thermoluminescent eye lens dosimeters were used to monitor the left and right eye lens doses of interventional radiology workers in real time during different surgical positions and varying eye protection conditions. The annual eye lens doses for the operators were estimated based on their yearly workload. The differences in eye lens doses under different conditions were analyzed and the influencing factors were identified. Results For individual interventional operations, the range of personal dose equivalent Hp(3) of the left eye of interventional radiology workers was ( < MDL ~ 418.33) μSv, the median (Q1, Q3) was 9.29 ( < MDL, 40.79) μSv, and the mean was 40.79 ± 70.36 μSv. The estimated annual eye lens doses were 4.05 mSv and 17.80 mSv based on the median and mean values of the eye lens dose of a single operation multiplied by average annual frequency of operations per person, respectively. The left eye lens dose was higher than the right eye lens dose of the same operator (Z = −4.24, P < 0.05), and the dose of the right eye lens was strongly positively correlated with that of the left eye lens. The left eye lens dose of the first surgeon was higher than that of the second surgeon in the same operation (Z = −3.10, P < 0.05). The eye lens dose was influenced by operator position (χ2 = 9.149, P = 0.002, OR = 8.343), eye protection (χ2 = 4.619, P = 0.032, OR = 4.352), and air kerma area product (χ2 = 8.032, P = 0.005, OR = 5.488). Conclusion According to the results of this study, a significant portion of interventional operators have eye lens doses that approach or exceed international occupational dose limits. It is recommended to pay attention to the operation frequency of the first operator and the air kerma area product of interventional operation, and strengthen radiation protection and dose monitoring for the eye lens of interventional radiology workers.

ObjectiveTo monitor the real-time changes in ammonia concentration in the laboratory animal facility environment before, during, and after the air conditioning system stops supplying air, so as to provide a basis and reference for developing emergency plans for the shutdown of the air conditioning system. MethodsThe laboratory animal facilities of the Wuhan Institute of Biological Products were used as the research object. Ammonia concentration detectors were used to monitor ammonia concentration continuously in the environment of conventional rabbit production facility, SPF hamster production facility, and SPF guinea pig experimental facility before and after the passive shutdown due to repairs and active maintenance shutdown of the air conditioning system, as well as the time for the ammonia concentration to return to daily levels after resuming air supply. ResultsUnder both shutdown modes of the air conditioning system, the trend of ammonia concentration changes in different laboratory animal facilities was consistent, showing a rapid increase after shutdown and a rapid decrease after resuming air supply. Under active maintenance shutdown, the maximum ammonia concentrations in the conventional rabbit production facilities, SPF hamster production facilities, and SPF guinea pig experimental facilities were 9.81 mg/m³, 14.27 mg/m³, and 6.98 mg/m³, respectively. Within 12 minutes after resuming air supply, ammonia concentration could return to normal daily levels. Under passive long-term shutdown, ammonia concentration value was positively correlated with the duration of air supply suspension. As the shutdown duration increased, ammonia concentration continued to increase. The maximum ammonia concentration values in the three facilities occurred at 88 minutes (38.06 mg/m³), 40 minutes (18.43 mg/m³), and 34 minutes (15.61 mg/m³) after air supply suspension, respectively.Within 11 minutes after resuming air supply, ammonia concentration could return to normal daily levels. ConclusionShutdown of the air conditioning system causes a rapid increase in ammonia concentration in laboratory animal facilities, and the rise in ammonia concentration is positively correlated with the duration of air supply suspension. Therefore, when an emergency shutdown of the air-conditioning system is required due to maintenance or other reasons, backup fans should be provided in accordance with the requirements of GB 50447-2008 "Architectural and Technical Code for Laboratory Animal Facilities". Older facilities should make adequate preparations and develop a scientifically sound emergency plan.

ObjectiveTo explore the protective effect and mechanism of Gegen Qianliantang (GQT) on intestinal mucosal barrier function in dextran sulfate sodium (DSS)-induced ulcerative colitis (UC) model mice. MethodsA UC model was established in C57BL/6 mice using a 2.5% DSS solution. Mice were randomly divided into five groups (n=8 per group): blank group, model group, mesalazine sustained-release granule group (0.52 g·kg-1), high-dose GQT group (2.23 g·kg-1), and low-dose GQT group (1.12 g·kg-1). Fecal characteristics and body weight changes were observed before and after treatment. The body weight loss and disease activity index (DAI) of UC mice were calculated to evaluate symptom severity. Hematoxylin-eosin (HE) staining and Alizarin blue-periodic acid-Schiff (AB-PAS) staining were used to detect histological changes in colon tissue. Immunohistochemistry was used to detect the expression of zonula occludens-1 (ZO-1) and mucin 2 (MUC2). Enzyme-linked immunosorbent assay (ELISA) was used to detect serum levels of pro-inflammatory cytokines interferon-γ (IFN-γ), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), IL-17A, and anti-inflammatory cytokine IL-10. Flow cytometry was used to detect the activation of helper T lymphocyte subsets (Th1, Th17), regulatory T cells (Treg), and regulatory B cells (Breg) in spleen and colon tissues. Western blot was used to detect the expression levels of T-bet, forkhead box protein P3(FoxP3), nuclear transcription factor(NF)-κB p65, phosphorylated NF-κB p65 (p-NF-κB p65), signal transducer and activator of transcription 3(STAT3), and phosphorylated STAT3 (p-STAT3). ResultsCompared with the model group, both high- and low-dose GQT groups significantly improved the body weight loss and DAI scores (P<0.05), alleviated colonic inflammation, and showed optimal efficacy in the high-dose group. AB-PAS staining showed that compared with the model group, both the high- and low-dose GQT groups significantly increased goblet cell proliferation and mucin secretion, indicating improved mucosal barrier function. GQT upregulated the expression of ZO-1 and MUC2 in colon tissue (P<0.05), suppressed IFN-γ, IL-6, and TNF-α secretion (P<0.05), elevated IL-10 secretion (P<0.05), but had no significant effect on IL-17A. At the same time, high- and low-dose GQT intervention increased the activation of CD4+ FoxP3+ Treg cells (P<0.05) and suppressed activation of CD4+ IFN-γ+ Th1 cells (P<0.05). Western blot showed that GQT downregulated T-bet, NF-κB p65, and STAT3 protein expression (P<0.05), upregulated FoxP3 (P<0.05), and also reduced phosphorylation levels of p-NF-κB p65 and p-STAT3 (P<0.05). ConclusionGQT can upregulate the activation of CD4+ FoxP3+ Treg cells, reduce the activation of CD4+ IFN-γ+ Th1 cells, inhibit the secretion of IFN-γ, IL-6, and TNF-α, and increase the secretion of IL-10. It enhances the expression of MUC2 and ZO-1 in colon tissue, thereby alleviating inflammatory damage to the intestinal mucosa and restoring mucosal barrier integrity. These effects may be related to its regulation of NF-κB p65 and STAT3 signaling pathways, ultimately regulating the activation of transcription factors T-bet and FoxP3.

ObjectiveTo investigate whether there are differences in the efficacy of Gegen Qinliantang with different contents of Puerariae Lobatae Radix on the acute enteritis (AE) model mice and provide a scientific basis for the interpretation of Gegen Qinliantang in the treatment of "Xie Re Li". MethodsA total of 112 male BALB/c mice were randomly divided into a blank group,model group,single Puerariae Lobatae Radix group,non-Puerariae Lobatae Radix group,regular dose Gegen Qinliantang group (regular dose group),half-dose Puerariae Lobatae Radix group,and doubled-dose Puerariae Lobatae Radix group, with 16 mice in each group. Hematoxylin-eosin (HE) staining was used to observe the pathological changes of the colon tissue. Western blot was employed to detect the expression of ZO-1 (a protein in the tight junction) and Occludin in the colon tissue, as well as the changes of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β). ResultsCompared with the blank group,the DAI scores of the mice in the model group were significantly higher (P<0.05),and the histopathological sections of their colon tissues showed mucosal damage,glandular atrophy,disordered arrangement,and a large number of inflammatory cells infiltration,and the expression of ZO-1 and Occludin proteins in their colon tissues was significantly down-regulated (P<0.05,P<0.01). The expression of inflammatory factors TNF-α and IL-1β was significantly up-regulated (P<0.05,P<0.01). Compared with the model group,the DAI scores of mice in all dosing groups decreased significantly (P<0.05),with the most significant effect in the regular dose group. After 7 d of drug administration,the regular dose group had the best impact on the repair of colonic mucosa in the AE mouse model. The regular dose group significantly down-regulated the expression of TNF-α (P<0.05) and significantly up-regulated the expression of ZO-1 protein (P<0.05). The doubled-dose Puerariae Lobatae Radix group significantly down-regulated the expression of IL-1β protein (P<0.01),and there was no significant difference between all dosing groups and the model group in terms of the expression of Occludin protein. After 14 d of drug administration,the best effect on the repair of colonic mucosa in the AE mouse model was observed in the doubled dose Puerariae Lobatae Radix group. All groups except the non-Puerariae Lobatae Radix group significantly down-regulated the expression of TNF-α (P<0.01). Meanwhile,the regular dose group and doubled-dose Puerariae Lobatae Radix group significantly elevated the expression level of Occludin protein (P<0.01). The doubled-dose Puerariae Lobatae Radix group also significantly inhibited the expression of IL-1β protein (P<0.05) and up-regulated ZO-1 protein expression (P<0.05). ConclusionGegen Qinliantang can reduce the pathological damage of colon tissue, protect the barrier function and structure of intestinal epithelial cells, and reduce the expression of inflammatory factors, so as to achieve the therapeutic effect of AE model mice. When comparing the therapeutic efficacy of Gegen Qinliantang containing different Gegen contents, Gegen Qinliantang with the proportion of the original formula of Zhongjing was the most effective in AE model mice.
