This paper summarizes clinical experience in treating acne based on the staged therapeutic principles of "eruption in warm diseases". It is considered that acne results from wind-heat retained in the lungs， invading the ying level and obstructing the blood collaterals， and is primarily a disorder involving both the wei and ying systems. In clinical practice， the treatment emphasizes the use of acrid-cool and sweet-cold methods. The core prescription is namely Yinqiaosan Qu Douchi Jia Xishengdi Danpi Daqingye Bei Xuanshen Fang （from Epidemic Warm Diseases ［《温病条辨》］）， and is adjusted according to the stage of disease. In the non-inflammatory stage， when the pathogen initially attacks the wei level， treatment focuses on acrid-cool herbs to release the exterior， with supplementary bitter-sweet ingredients such as Yejuhua （Chrysanthemum Indicum）. In the inflammatory stage， with pronounced heat toxin in the qi level affecting the ying and blood， and local stagnation of qi and blood， the approach is to clear heat and resolve toxin， using blood-cooling and stasis-resolving herbs early to prevent progression. Herbs such as Pugongying （Taraxacum Mongolicum）， Zihuadiding （Viola Yedoensis）， Tiankuizi （Semiaquilegia Adoxoides）， Chonglou （Paris Polyphylla）， Machixian （Portulaca Oleracea）， Zaojiaoci （Gleditsia Sinensis）， Chuanshanjia （Manis Pentadactyla） may be added. In the post-inflammatory erythema stage， when yin of the ying level is depleted and internal deficiency-heat arises， sweet-cold herbs are recommended to nourish the stomach and generate fluids， with the possible addition of Yiwei Decoction （益胃汤）.

This study aimed to investigate the effect and mechanism of Buyang Huanwu Decoction in regulating endoplasmic reticulum stress via the inositol-requiring enzyme 1α(IRE1α)/apoptosis signal-regulating kinase 1(ASK1)/c-Jun N-terminal kinase(JNK) pathway to improve neurological function in rats with cerebral ischemia/reperfusion injury(CIRI). SPF-grade male sprague-dawley(SD) rats were randomly divided into Sham group, model group, Buyang Huanwu Decoction group, and edaravone group. Except for the Sham group, the other groups were subjected to the modified suture method to establish a middle cerebral artery occlusion/reperfusion(MCAO/R) model. After treatment, neurological function was assessed using the Zea Longa scoring system. Gait analysis was used to detect the motor function. Detection of relative infarct area in brain tissue using 2,3,5-triphenyltetrazolium chloride(TTC) staining. Nissl staining was used to observe the structure of neuronal cells. Western blot and real-time fluorescence quantitative PCR(RT-qPCR) were used to detect IRE1α, ASK1, JNK, B cell lymphoma-2(Bcl-2), Bcl-2 related X protein(Bax), and Caspase-3 in the brain tissue. Immunohistochemistry was used to detect the positive expression of IRE1α, ASK1, and JNK. Immunofluorescence was used to detect the fluorescence expression levels of Bax, Bcl-2, and Caspase-3. The results showed that compared with the Sham group, the model group exhibited increased neurological scores(P<0.01), increased ratio of ground contact area and strength in both forelimbs(P<0.01), enlarged relative infarct area of brain tissue(P<0.05), and a reduced number of Nissl staining-positive cells(P<0.01). The protein and mRNA expression levels of IRE1α, ASK1, JNK, Bax, and Caspase-3 in brain tissue were significantly elevated, while those of Bcl-2 were decreased(P<0.05). Compared with the model group, both the Buyang Huanwu Decoction group and edaravone group showed reduced neurological scores(P<0.05), decreased ratio of ground contact area and strength in both forelimbs(P<0.05), smaller relative infarct area(P<0.05), alleviated neuronal damage, and increased number of Nissl staining-positive cells(P<0.05). The expression levels of IRE1α, ASK1, JNK, Bax, and Caspase-3 protein and mRNA in brain tissue were significantly reduced, while those of Bcl-2 were significantly increased(P<0.05). The results indicated that Buyang Huanwu Decoction can effectively improve brain injury in CIRI rats, and its mechanism of action may be related to regulating the endoplasmic reticulum stress IRE1α/ASK1/JNK signaling pathway.

Pyoderma gangrenosum(PG)is a rare autoinflammatory disease,characterized mainly by painful and necrotic skin ulcers.The etiology of PG is unknown,and its treatment is quite challenging.This article reports a case of recurrent pyoderma gangrenosum successfully treated with adalimumab combined with tofacitinib,along with a review of relevant literature.The patient,a 54-year-old male,presented with scrotal ulcers accompanied by pain for 20 days,worsening and involving the groin area for 5 days,and fever for 1 day.Dermatological examination revealed two painful ulcers on the scrotum with raised edges,clear boundaries,and a small amount of purulent discharge on the surface;the right groin area and the medial left thigh showed irregular infiltrative erythematous plaques,with scattered clustered pustules on them,central necrosis appearing purplish-brown,surrounded by a red halo with clear boundaries.Based on the patient's past medical history,clinical manifestations,and auxiliary examinations,the diagnosis was consistent with pyoderma gangrenosum.After treatment with adalimumab combined with tofacitinib,the patient's symptoms were significantly improved,and the ulcers healed.At the 6-month follow-up,the skin lesions had not recurred.For refractory PG that is ineffective to conventional treatments,adalimumab combined with tofacitinib is an effective and safe treatment option,providing a new combination therapy regimen for PG.

Objective To explore the relationship between levels of vascular endothelial growth factor(VEGF),insulin-like growth factor 1(IGF-1),and transforming growth factor-β1(TGF-β1)in the synovial fluid of children with avascular necrosis of the femoral head(also known as Perthes disease)and the efficacy of postoperative revascularization,aiming to provide a basis for subsequent diagnosis and treatment.Methods A retrospective study was conducted on 262 children with Perthes disease admitted to the Affiliated Hospital of Gansu University of Chinese Medicine from January 2023 to June 2024.Based on postoperative revascularization efficacy,patients were divided into good revascularization group(n=228)and poor revascularization group(n=34).For poor revascularization group,a 1:2 matched case-control design was used to select 68 age-matched children with hip synovitis who underwent hip joint fluid puncture as control group.Additionally,82 children with Perthes disease treated at the hospital from June 2024 to January 2025 were enrolled as a validation cohort for nomogram model verification.The expression levels of VEGF,IGF-1 and TGF-β1 in the synovial fluid of three groups were compared.Confounding biases were controlled through univariate and stratified analyses.Binary logistic regression analysis was used to identify independent factors affecting the revascularization effect.R software was utilized to draw and verify the nomogram model for predicting the postoperative revascularization effect.Results The levels of VEGF,IGF-1 and TGF-β1 in the synovial fluid of children in poor revascularization group were all higher than those in control group and good revascularization group(P<0.05).After three types of reconstructive surgeries,the levels of VEGF,IGF-1 and TGF-β1 in the synovial fluid of children with poor revascularization were all higher than those in children with good revascularization(P<0.05);however,there was no statistically significant difference in the above indicators among different surgical types(P>0.05).Binary logistic regression analysis showed that the levels of VEGF,IGF-1,and TGF-β1 in the synovial fluid were independent risk factors for poor postoperative revascularization in children with Perthes disease.The area under the ROC curve of the nomogram model established accordingly for predicting poor postoperative revascularization in children with Perthes disease was 0.875(95%CI 0.805-0.945),with a sensitivity of 0.874 and a specificity of 0.851.Moreover,the calibration curve and decision curve analysis(DCA)indicated that the model had good clinical applicability.Conclusions The increased levels of VEGF,IGF-1 and TGF-β1 in synovial fluid are associated with poor postoperative revascularization in children with Perthes disease.These three factors are expected to become prognostic indicators for children with Perthes disease.

Data analysis models may assist the transmission of traditional Chinese medicine （TCM） experience and clinical diagnosis and treatment， and the possibility of constructing a “data-knowledge” dual-drive model was explored by taking gastric precancerous state as an example. Data-driven is to make clinical decisions around data analysis， and its syndrome-differentiation decision-making research relies on hidden structural models and partially observable Markov decision-making processes to identify the etiology of diseases， syndrome elements， evolution of pathogenesis， and syndrome differentiation protocols； knowledge-driven is to make use of data and information to promote decision-making and action processes， and its syndrome-differentiation decision-making research relies on convolutional neural networks to improve the accuracy of local disease identification and syndrome differentiation. The “data-knowledge” dual-driven model can make up for the shortcomings of single-drive numerical simulation accuracy， and achieve a balance between local disease identification and macroscopic syndrome differentiation. On the basis of previous research， we explored the construction method of diagnostic assisted decision-making platform for gastric precancerous state， and believed that the diagnostic and decision-making ability of doctors can be extended through the assistance of machines and algorithms. Meanwhile， the related research methods were integrated and the core features of gastric precancerous state based on TCM syndrome differentiation and endoscopic pathology diagnosis and prediction were obtained， and the elements of endoscopic pathology recognition based on TCM syndrome differentiation were explored， so as to provide ideas for the in-depth research and innovative application of cutting-edge data analysis technology in the field of intelligent TCM syndrome differentiation.

Objective:To establish a method for obtaining planning target volume (PTV) and planning risk volume (PRV) margins caused by rotation in the use of adapt-to-position (ATP) modality of magnetic resonance linear accelerator (MRL) for patients with intracranial tumors.Methods:Clinical data of 6 patients with intracranial tumors (150 fractions in total) who received MRI-guided online ATP radiotherapy in Peking Union Medical College Hospital from November 2023 to January 2024 were retrospectively analyzed. The pre-planned CT structure was copied onto each segmented MR image and then the structures were traced back to the CT image according to the three-dimensional registration relationship. The anisotropic distance of the structure based on the original CT structure was calculated to obtain the variation range of the target and the organs at risk. The maximum anisotropic value was taken as the result of the PTV and the relationship between the results and intracranial location of different patients was analyzed. Group comparison was performed by Chi-square test. Two group comparison was conducted by post-hoc Wilcoxon signed-rank test. Results:After the rotation deviation was included, the range of target changes in the six directions of left and right (L/R), anterior and posterior (A/P) and superior and inferior (S/I) of the 6 patients were: (1.24± 0.86) mm/(1.91± 1.07) mm, (2.02± 1.26) mm/(1.66± 1.07) mm, (1.84± 1.84) mm /(2.94±1.93) mm, respectively. The results in the SI direction were significantly different, and the values in the I direction in 2 patients exceeded 4 mm, the margins suitable for all patients were 3.01 mm/2.4 mm(A/P), 1.9 mm/2.93 mm(L/R) and 3.14 mm/4.62 mm(S/I) in different directions, respectively. The L/R direction of the lens and the S/I direction of the optic nerve were significantly changed, and the A/P direction of the brain stem was (3.99± 4.64) mm. Larger values might be required when the target was in the posterior brain (left-down area, right-down area).Conclusions:The rotation deviation, organ movement and intracranial location affect the PTV and the organs at risk PRV in the MRI-guided ATP modality in intracranial tumors patients. The margin generation method based on image fusion can help to quantify the margin value reasonably.

Abstract: Objective To investigate the efficacy of capreomycin adjuvant therapy for multidrug-resistant pulmonary tuberculosis (MDR-TB) and its effect on quality of life and immune function. Methods Eighty-eight elderly pulmonary tuberculosis patients admitted to Affiliated Hospital of Hebei University from October 2019 to October 2020 were selected and divided into two groups according to the random number table method. The control group (n=44) used 4-6Am-Mfx（Lfx）-Pto-Cfz-Z-Hhigh-dose-E/5 Mfx（Lfx）-Cfz-Z-E, the research group (n=44) used capreomycin on the basis of the control group. The 6-Minute Walk Test (6MWT) measured value/predicted value and quality of life [36-Item Short Form Health Survey Questionnaire (SF-36)] scores, safety evaluation results, chest CT cavity and lesion absorption rate and sputum culture turned negative were compared between the two groups, and the serum procalcitonin (PCT) expression levels and immune function were detected before and after treatment. Results The 6MWT measured value/predicted value of the research group and control group before the treatment were (0.48±0.11) and (0.64±0.13), which were significantly higher than corresponding (0.51±0.12) and (0.58±0.14) after treatment (t=6.23, 2.520, P<0.05), the measured/expected value of 6MWT increased in both groups after treatment. Compared with the same group before treatment, the SF-36 scores for each dimension increased in both groups after treatment (P<0.01). The expression levels of serum PCT in the research group and control group before the treatment were (0.37±0.09) ng/mL and (0.12±0.03) ng/mL versus (0.36±0.11) ng/mL and (0.21±0.06) ng/mL after treatment (t=17.480, 7.940, P<0.01). Compared with the same group before treatment, serum PCT expression levels decreased in both groups after treatment. Compared with the same group before treatment, CD3+, CD4+ and CD4+/CD8+ were elevated in both groups after treatment (P<0.05 or P<0.01); after treatment, CD3+, CD4+, and CD4+/CD8+ were significantly higher in research group compared to the control group (t=4.21, 8.02, 2.04, P<0.05). The absorption rate of chest CT cavity and lesions and negative rate of sputum culture in the research group were 88.64% (39/44) and 81.82% (36/44), which were significantly higher than corresponding 63.64% (28/44) and 61.36% (27/44) in the control group (P<0.05). Conclusions　Capreomycin can improve the quality of life of MDR-TB patients, extend the 6-minute walking distance, and regulate serum PCT expression levels and immune function, to promote the absorption of chest CT cavity and lesions, and sputum culture to turn negative, and the security is acceptable.
