Qingfeitang， specialized in resolving phlegm to stop cough and producing fluid to moisten dryness， is a classic prescription inherited and developed by physicians of successive generations and has been included in the Catalogue of Ancient Classic Prescriptions （First Batch） published by the National Administration of Traditional Chinese Medicine （TCM） in 2018. Relevant ancient books data and modern literature were collected by bibliometrics to analyze the historic origin， formula composition， herb origin， preparation methods， processing methods， clinical effect， and indications of Qingfeitang. The key information of Qingfeitang was summarized to provide reference for the clinical application of the decoction. In this study， a total of 43 pieces of effective data on relevant ancient literature， including 35 ancient TCM books， were collected based on a systematic collation of relevant historic and modern literature. Results showed that "Qingfeitang" was originated from the "Renshen Qingfeitang" recorded in the Taiping Holy Prescriptions for Universal Relief from the Qing dynasty. The name of "Qinfeitang" was first recorded in the Yeshi Luyanfang written by YE Dalian in the Song dynasty. We suggested the modern dosage and usage of Qingfeitang as follows： "Scutellariae Radix of 5.60 g， Platycodon grandiflora， Poria， Tangerine， Fritillaria， and Cortex Mori of 3.73 g respectively， Angelicae Sinensis Radix， Asparagi Radix， Gardeniae Fructus， Armeniacae Semen Amarum， and Ophiopogonis Radix of 2.61 g respectively， Schisandra of 1 g， and Glycyrrhizae Radix et Rhizoma of 1.12 g， and they were taken 3 times daily. The above formula is recommended to be decocted with 400 mL of water， with 3.37 g ginger and 6 g jujubae fructus， to 320 mL， and taken after a meal， three times per day". Qingfeitang has the effect of resolving phlegm to stop cough and producing fluid to moisten dryness， specialized in treating cough， asthma， rash， and other symptoms in ancient times. Modern applications are mainly focused on the respiratory system， used for treating diseases such as bronchopneumonia and cough. The above research results provide a reference basis for the later development and research of Qingfeitang.

Objective:To investigate the effect of the antioxidant Tempol on the skin depigmentation of a vitiligo-like mouse model induced by the combination of the endogenous reactive oxygen species (ROS) producer AAPH and tyrosinase-related protein 2 (TRP2) -180 nonapeptide.Methods:A vitiligo-like skin depigmentation model was established by immunizing mice with injections of a TRP2-180 nonapeptide mixture into the foot pads twice and into the tails twice, with the injection interval being 1 week. After the first injection, 12 immune-induced mouse models of vitiligo were randomly divided into 4 groups (3 mice per group) : a model group, an AAPH group, a Tempol group, and a combined treatment group; additionally, 3 untreated mice injected with an ovalbumin (OVA) 257-264 peptide served as a sham control group. Mice in the AAPH group, the Tempol group, and the combined treatment group were subcutaneously injected with AAPH into the tails, intraperitoneally injected with Tempol, and received the above both treatments, respectively, while mice in the model group and the sham control group received phosphate-buffered saline injections into the tail and/or abdomen. Drug interventions were carried out 3 times per week for 3 consecutive weeks. Six weeks after the last immunization, mice were sacrificed. The area of depigmented macules on the tail was measured using a point-counting method, X-gal staining and double immunofluorescence staining were performed to assess the distribution and number of melanocytes, mast cells, and CD8 + T cells in depigmented macules on the tail. HaCaT cells were in vitro co-cultured with AAPH and/or Tempol, and a conventional culture group served as the control. Cellular ROS levels were measured by dichlorofluorescin diacetate labeling and flow cytometry; Western blot analysis was performed to determine the expression of matrix metalloproteinase 9 (MMP9) and stem cell factor (SCF) in cell lysates, and to detect soluble SCF levels in the culture supernatant. Comparisons among multiple groups were conducted using one-way analysis of variance, and multiple comparisons were performed using least significant difference- t test. Results:Depigmented macules were observed on the tails of mice in all groups except the sham control group. The area of depigmented macules was significantly larger in the AAPH group (7.27 ± 0.31 cm 2) than in the model group and combined treatment group (3.53 ± 0.21 cm 2, 4.07 ± 0.40 cm 2; t = 13.48, 11.56, respectively, both P < 0.001), while there was no significant difference between the Tempol group (3.30 ± 0.40 cm 2) and the model group ( P = 0.424). X-gal staining and double immunofluorescence staining showed that the number of melanocytes in the normal skin around the depigmented macules was significantly lower in the AAPH group and the combined treatment group than in the model group ( t = 6.31, 5.16, respectively, both P < 0.001), and no significant difference was observed between the AAPH group and the combined treatment group ( P = 0.516). The numbers of CD8 + T cells and mast cells were significantly higher in the AAPH group than in the model group and the combined treatment group (all P < 0.001). The numbers of the 3 types of cells mentioned above in the Tempol group did not differ from those in the model group (all P > 0.05). The ROS levels in HaCaT cells in the AAPH group were the highest, and significantly higher than those in the control group and the combined treatment group (both P < 0.001). Western blot analysis showed that the MMP9 level in the cell lysates and soluble SCF level in the culture supernatant were significantly higher in the AAPH group than in the control group and the combined treatment group (all P < 0.05) ; no significant difference was observed in the membrane-bound SCF level in cell lysates among the groups ( F = 0.06, P = 0.977) . Conclusion:The antioxidant Tempol could inhibit the formation of skin depigmented macules in vitiligo-like mouse models under AAPH-induced oxidative stress.

Objective:To investigate effects of rutin on ultraviolet irradiation (UVR) -induced human dermal fibroblast (FB) senescence and melanogenesis in mouse ear skin.Methods:The third- to fifth-passage FBs were divided into 4 groups: a blank control group, a UVR group, a rutin group, and a combined treatment group. In the UVR group, FBs were irradiated using an ultraviolet irradiator at a single dose of 0.6 J/cm 2 UVA combined with 0.03 J/cm 2 UVB once daily for 5 consecutive days; FBs in the rutin group were cultured in Dulbecco's modified Eagle medium containing 50 μmol/L rutin for 5 days; the combined treatment group received both UVR and the treatment with 50 μmol/L rutin for 5 days; the blank control group underwent no treatment. β-Galactosidase staining was performed to assess the senescence of FBs, real-time quantitative PCR (qPCR) to measure the telomere length in FBs, and Western blot analysis to detect the expression levels of stem cell factor (SCF) in FB cell lysates and culture supernatants. FB culture supernatants were collected from each group, and mixed with M254 medium at a ratio of 3∶1 to prepare conditioned medium, which was then used to treat PIG1 melanocytes for 24 hours. Western blot analysis was conducted to determine the tyrosinase (TYR) expression in PIG1 melanocytes in each group, while the 5-ethynyl-2′-deoxyuridine (EdU) incorporation assay was applied to assess the proliferative activity of PIG1 cells in each group. Ten Dct-LacZ transgenic mice were divided into a control group and a UVR group. For each mouse, 5% rutin-containing cream was topically applied to the right ear after UVR, while the left ear treated with the cream base alone served as a control. Skin biopsies were performed after 4 weeks, followed by X-gal staining and Avidin/fluorescein isothiocyanate (FITC) staining to count the numbers of melanocytes and mast cells in mouse ear skin. Results:In the UVR group, the number of senescent FBs (25.67 ± 2.89), relative protein expression levels of SCF (1.95 ± 0.22), and relative levels of SCF in the cell culture supernatant (1.52 ± 0.34) were all significantly higher than those in the blank control group (5.67 ± 1.56, 0.95 ± 0.11, 1.01 ± 0.31, respectively), while these indicators were significantly lower in the combined treatment group (12.00 ± 1.63, 1.32 ± 0.19, 1.15 ± 0.32, respectively) than in the UVR group (all P < 0.05). The relative telomere length in FBs was significantly shorter in the UVR group (0.49 ± 0.12) than in the blank control group (0.94 ± 0.11; LSD- t = 3.15, P = 0.021), but significantly longer in the combined treatment group (0.81 ± 0.13) than in the UVR group (LSD- t = 4.30, P = 0.034). After the treatment with FB conditioned medium, the relative expression level of TYR in PIG1 melanocytes and the number of EdU-positive cells were significantly higher in the UVR group (2.54 ± 0.21, 33.54 ± 3.21, respectively) than in the blank control group (0.97 ± 0.19, 21.45 ± 2.51, respectively; both P < 0.001), but significantly lower in the combined treatment group (1.63 ± 0.12, 18.54 ± 3.87, respectively) than in the UVR group (both P < 0.001). X-gal staining and Avidin/FITC staining showed that the numbers of melanocytes and mast cells in the mouse left ear skin in the UVR group (5.00 ± 1.22, 98.60 ± 8.47, respectively) were significantly higher than those in the mouse left ear skin in the control group (1.80 ± 0.45, 53.80 ± 5.76, respectively) and those in the mouse right ear skin treated with the rutin-containing cream in the UVR group (2.80 ± 0.45, 69.60 ± 8.89, respectively) (all P < 0.05) . Conclusion:Rutin may inhibit UVR-induced skin melanogenesis by suppressing the senescence of dermal FBs and paracrine secretion of SCF.

The classical prescription Yangweitang， derived from Zhengzhi Zhunsheng， is specialized in treating syndromes of chill and fever due to exogenous pathogens， inner-cooling， and malaria， and it has been included in the Catalogue of Ancient Classical Formulas （the First Batch） published by the National Administration of Traditional Chinese Medicine （TCM） in 2018. Through bibliographical research， the relevant ancient books and modern documents were systematically sorted out， and it was found that there were many prescriptions related to the Yangweitang from Zhengzhi Zhunsheng. They were interwoven with Yangweitang from Zhengzhi Zhunsheng and widely used in clinical practice. In order to clarify their history and evolution， this paper combed the historical origin of Yangweitang and its related prescriptions and conducted textual analysis on key information such as semantic composition， herb origin， processing method， and efficacy. A total of 896 pieces of data on Yangweitang from Zhengzhi Zhunsheng were collected. 26 pieces of effective data were included after the screening， involving 17 ancient TCM books. Then， a total of 28 pieces of data on prescriptions related to the Yangweitang from Zhengzhi Zhunsheng were included， involving 23 ancient TCM books for reference. The textual analysis showed that Yangweitang originated from the Renshen Yangweitang recorded in Taiping Huimin Heji Jufang in the Song dynasty. Based on the original formula， medical experts from later generations have modified it into many different versions. A comparative analysis showed that Yangweitang from different generations had similar compositions， and the herb origin and processing method were basically clear. The recommended prescriptions are as follows： 37.3 g of Pinelliae Rhizoma Praeparatum Cum Alumine， Magnoliae Officinalis Cortex（fried with ginger juice）， and frying with rice water Atractlodis Rhizoma， 27.98 g of Citri Exocarpium Rubrum， 18.65 g of Pogostemon cablin leaf， Tsaoko Fructus， Poria， and Ginseng Radix et Rhizoma， and 9.33 g of Glycyrrhizae Radix et Rhizoma. They could be ground into a coarse powder， with 14.92 g for every dose， and they could be orally taken after being decocted with 450 mL of water， 7 g of fresh ginger， and 2 g of Mume Fructus to 270 mL in warm conditions. Yangweitang from Zhengzhi Zhunsheng has the effect of warming the middle and releasing the external， and it can treat many syndromes including spleen and stomach disharmony caused by chill and fever due to exogenous pathogens and inner-cooling， as well as all kinds of malaria. Modern clinical applications mainly focus on chronic atrophic gastritis and other digestive system diseases.

This paper discussed the historic evolution of Juanbitang and similar decoctions， clarified the historic development of Yangshi Juanbitang and Chengshi Juanbitang， and probed into the key information of the meaning， original plants， processing methods， and modern dosage and usage of Chengshi Juanbitang. A total of 267 pieces of relevant information were collected from ancient traditional Chinese medicine （TCM） books， among which 53 pieces of effective data were included in this study. The results showed that both Chenshi Juanbitang and Yangshi Juanbitang were originated from Duhuo Jishengtang recoded in the Important Prescriptions Worth a Thousand Gold for Emergency （Bei Ji Qian Jin Yao Fang）. According to the standard of "1 qian roughly equals 3.73 g" in the measurement system of the Qing Dynasty， we suggest Chenshi Juanbitang is composed of 3.73 g Notopterygii Rhizoma et Radix， 3.73 g Angelicae Pubescentis Radix， 3.73 g Gentianae Macrophyllae Radix， 11.19 g Angelicae Sinensis Radix， 11.19 g Mori Ramulus， 2.61 g Chuanxiong Rhizoma， 1.87 g Cinnamomi Cortex， 1.87 g stir-fried Glycyrrhizae Radix et Rhizoma， 7.46 g Piperis Kadsurae Caulis， 2.98 g Olibanum， and 2.98 g Aucklandiae Radix， which should be decocted with 600 mL water to reach a volume of 300 mL. The decoction should be taken 3 times a day before meals. Juanbitang， a classical formula specialized for treating impediment diseases， has the effects of dispelling wind， removing dryness， and alleviating impediment to relieve pain. It can be used for treating vexing pain in body， spasm of nape and back， and heaviness in waists and legs. Modern studies have shown that Juanbitang can be used for treating rheumatoid arthritis， knee osteoarthritis， and periarthritis of shoulder. The above results served as a reference for the future development of Juanbitang.

Objective:To analyze the correlation between the skin temperature changes in the radiation area and the occurrence of radiodermatitis during postoperative radiotherapy for female breast cancer and to explore the application value of skin temperature monitoring in the early warning of radiodermatitis risks.Methods:A total of 103 patients who received three-dimensional conformal radiotherapy after radical mastectomy in the Fourth Hospital of Hebei Medical University were continuously enrolled from May to November, 2022 in this study. Their skin temperature in the radiation area and radiodermatitis were recorded weekly. The relationships between relative skin temperature differences and different grades of radiodermatitis were determined. The optimal cut-off values for grade ≥ radiodermatitis were calculated, and the predictive effect was evaluated using the receiver operating characteristic (ROC) curve. Furthermore, the radiodermatitis risks under different skin temperatures were compared using binary logistic regression.Results:There was a positive correlation between the skin temperature in the radiation field and the grade of radiodermatitis. The optimal cut-off values for the average relative skin temperature difference of the chest wall (under 40 Gy/20 fractions), the maximum relative skin temperature difference of the chest wall (under 40 Gy/20 fractions), and the relative skin temperature difference of the supraclavicular block (under 30 Gy/15 fractions) were 0.45℃, 0.55℃, 0.15℃, respectively. The patients were divided into low- and high-risk groups based on the optimal cut-off values (0.45℃, 0.55℃, and 0.15℃). Binary logistic regression result showed that the risks of grade ≥ 2 radiodermatitis in the high-risk group were 5.71, 4.29, and 5.15 times those in the low-risk group, respectively ( OR = 5.71, 95% CI 1.81-17.99, P = 0.003; OR = 4.29, 95% CI 1.65-11.12, P = 0.003; OR = 5.15, 95% CI 2.16-12.31, P < 0.001). Conclusions:Skin temperature monitoring using medical infrared thermometers can be used to effectively predict the occurrence of grade ≥ 2 radiodermatitis. The skin temperature changes in the radiotherapy area should be closely observed. The risk of grade ≥ 2 radiodermatitis will increase when the mean and maximum relative temperature differences of the chest wall increase by 0.45℃ and 0.55℃, respectively under 40 Gy/20 fractions of radiotherapy or when the relative temperature differences of the supraclavicular block increases by 0.15℃ under 30 Gy/15 fractions of radiotherapy.

Objective The combined detection of serum angiopoietin-like protein 8(ANGPTL8)and Vascular cell adhesion molecule-1(VCAM-1)levels was analyzed for the predictive value of cerebral vasospasm(CVS)after intracranial aneurysm embolization.Methods A total of 196 patients who underwent intracranial aneurysm embolization in our hospital from March 2019-March 2022 were selected as the study subjects,99 patients with CVS were in the CVS group,and 97 patients without CVS were in the non CVS group.Serum ANGPTL8 and VCAM-1 levels were detected by ELISA;the correlation between serum ANGPTL8 and VCAM-1 levels was analyzed by Pearson method,Logistic regression was used to analyze the influencing factors of CVS in patients undergoing intracranial aneurysm embolization;ROC curve was used to analyze the serum levels of ANGPTL8 and VCAM-1 to predict the cutoff value of CVS in patients undergoing intracranial aneurysm embolization;four grid table method was used to analyze the predictive value of ANGPTL8,VCAM-1 and their combination on the occurrence of CVS in patients undergoing intracranial aneurysm embolization.Results The differences between CVS and non-CVS groups were statistically significant in hypertension,Hunt-Hess grade,and Glasgow coma(GCS)scores(P＜0.05).The serum ANGPTL8 and VCAM-1 levels in the CVS group were significantly higher than those in the non-CVS group(P＜0.05).There was a positive correlation between serum ANGPTL8 and VCAM-1(r=0.468,P＜0.05).Multivariate analysis showed that high level of ANGPTL8(OR=3.652,95％CI:1.434-9.302),high level of VCAM-1(OR=2.619,95％CI:1.212-5.658),Hunt Hess grade Ⅲ-Ⅳ(OR=1.927,95％CI:1.104-3.362),GCS score of 3-8(OR=2.813,95％CI:1.257-6.295)were independent risk factors for CVS in patients undergoing intracranial aneurysm embolization.The AUC of serum ANGPTL8 level in predicting CVS in patients undergoing intracranial aneurysm embolization was 0.844,and the cut-off value was 189.233 U/L;the AUC of serum VCAM-1 level in predicting CVS in patients undergoing intracranial aneurysm embolization was 0.795,and the cutoff value was 17.984 mg/L.The accuracy,sensitivity and specificity of the combined prediction for CVS were 89.81％,93.94％and 85.57％,respectively,which were obviously higher than those of the single prediction.Conclusion The serum levels of ANGPTL8 and VCAM-1 in CVS group are obviously higher than those in non CVS group.The combination of the two has a high predictive value for CVS after intracranial aneurysm embolization.

A 10-day-old male infant presented with skin erythema and blisters for 6 days. Skin examination showed scattered or confluent erythema all over the body, tense blisters of varying sizes on the normal skin or an erythematous base, and some blisters were ulcerated and erosive; bloody bullae and erythematous erosive patches could be seen on the oral mucosa. Histopathological examination revealed subepidermal blisters, and there were some neutrophils and a few eosinophils in the blisters. Direct immunofluorescence assay showed homogeneous linear IgA and granular C3 deposits along the basement membrane zone, without IgG deposits. The diagnosis of neonatal linear IgA bullous dermatosis was confirmed. After comprehensive treatments including nutritional support and anti-infection treatment, skin erythema and blisters subsided, and the mucosal damage was attenuated. The telephone follow-up 16 months after discharge showed that the infant was in good general condition with normal growth and development, and the oral mucosal lesions had subsided and healed, without new skin lesions.
