This paper summarizes Professor AI Rudi's experience in the diagnosis and treatment of skin pruritus based on the "unity of restoring form， regulating qi， and harmonizing spirit"， employing internal herbal medicine combined with external treatments. It is believed that the core pathogenesis of pruritus is the "imbalance of form， qi， and spirit"， with disturbed spirit as the onset， disordered qi as the key pathogenic factor， and physical changes as the manifestation of the disease. The treatment principle follows "restoring form-regulating qi-harmonizing spirit"， with a combination of internal and external therapies， and differentiation based on deficiency and excess. For excess conditions caused by pathogenic disturbances to the heart spirit， treatment is based on different patterns of wind-heat， damp-heat， and blood-heat， using Sangye （Morus alba）-Sangbaipi （Morus alba cortex）-Longchi （Draconis os） to disperse wind and clear heat， calm the spirit； Difuzi （Kochia scoparia）-Qinghao （Artemisia annua）-Tanxiang （Santalum album） to clear damp-heat and aromatically open the spirit； Mudanpi （Paeonia suffruticosa）-Chuanxiong （Ligusticum chuanxiong）-Shuiniujiao （Bubalus bubalis cornua） to cool the blood， activate circulation， and calm the spirit. For deficiency conditions caused by insufficient nourishment of the heart spirit， treatment is based on patterns of qi deficiency or blood deficiency， using Huangqi （Astragalus membranaceus）-Fuping （Lemna minor）-Wuweizi （Schisandra chinensis） to tonify the qi and stabilize the exterior； Heshouwu （Polygonum multiflorum）-Jili （Tribulus terrestris）-Shouwuteng （Polygonum multiflorum vine） to nourish the blood， moisten dryness， and calm the spirit. External treatments integrate traditional Chinese medicine therapies such as medicinal baths， gua sha， and ear acupuncture， with custom herbal wash formulas for restoring form， jojoba oil gua sha for regulating qi， and ear seed therapy using Wangbuliuxing （Vaccaria segetalis） for harmonizing the spirit， achieving a holistic treatment effect for form， qi， and spirit.

This paper summarizes Professor AI Rudi's clinical experience in treating skin abscesses using the method of "three parts and six methods"， which emphasize a combined internal and external therapeutic approach. He identifies retained pathogenic heat in the skin as the key etiological factor and proposes treatment principles tailored to the anatomical location of the lesions. For abscesses in the upper part of the body （head， face and neck）， wind-heat and blood-heat are considered dominant， and the treatment focuses on dispersing the exterior， clearing heat， cooling the blood， and reducing swelling， with custom formulations such as self-fomulated Shufeng Xiaodu Decoction （疏风消毒饮） and Jiedu Xiaozhong Decoction （解毒消肿汤）. For those in the middle part of the body （chest， abdomen， back and upper limbs）， constrained heat and deficiency-heat predominate， and the treatment aims to relieve internal heat stagnation， reduce swelling， and expel toxins， using formulations like self-fomulated Qinggan Jiedu Decoction （清肝解毒汤） and Xiaozhong Erchen Decoction （消肿二陈汤）. For abscesses in the lower part of the body in the （buttocks， perineum and lower limbs）， damp-heat and stagnant heat are the main patterns， and the strategy is to clear damp-heat and resolve blood stasis， with formulations such as self-fomulated Jiedu Simiao Powder （解毒四妙散） and Qingjie Sanyu Decoction （清解散瘀汤）. External therapies are equally emphasized： for unruptured lesions， self-fomulated Wumiao Ointment （五妙膏） is used to detoxify and reduce swelling， while for ruptured lesions， Danhuang Oil （蛋黄油） is applied to promote wound healing and relieve pain.

ObjectiveTo explore the effect and mechanism of modified Dingjingtang in regulating the Toll-like receptor 2 （TLR2）/nuclear factor （NF）-κB/NOD-like receptor protein 3 （NLRP3） signaling pathway to inhibit inflammatory skin lesions in the rat model of acne. MethodsForty-eight rats were randomized into the normal， model， low-， medium-， and high-dose （8.1， 16.2， and 32.4 g·kg^-1） modified Dingjingtang， and doxycycline hydrochloride （0.27 g·kg^-1） groups， with 8 rats in each group. Rats in other groups except the normal group were modeled by intradermal injection and intraperitoneal injection of Propionibacterium acnes. After successful modeling， rats in the intervention groups were treated with corresponding agents by gavage， and those in the normal and model groups with an equal volume of normal saline， once a day for 14 consecutive days. Then， the samples were collected. The general conditions， ear thickness， and body weight changes of rats were observed. Biochemical methods were used to determine superoxide dismutase （SOD） and malondialdehyde （MDA） levels in the ear tissue. Hematoxylin-eosin staining and Masson's staining were used to observe the pathological changes and collagen deposition， respectively， in the ear tissue. Immunohistochemistry was employed to determine the interleukin （IL）-1β level in the ear tissue. Enzyme-linked immunosorbent assay was adopted to measure the levels of IL-1β， tumor necrosis factor （TNF）-α， and IL-6 in the serum. The total antioxidant capacity method was adopted to assess the reactive oxygen species （ROS） content in the ear tissue. Western blot and real-time fluorescence quantitative polymerase chain reaction were employed to determine the protein and mRNA levels， respectively， of TLR2， myeloid differentiation factor 88 （MyD88）， NF-κB， NLRP3， and cysteinyl aspartate-specific proteinase-1 （Caspase-1） in the ear tissue. ResultsCompared with the normal group， the model group had increased ear skin thickness （P<0.01）， elevated ROS and MDA levels （P<0.01）， reduced SOD content （P<0.05）， and increased collagen deposition （P<0.01） in the ear tissue. In addition， the model group showed raised IL-1β， IL-6， and TNF-α levels in the serum （P<0.01） and up-regulated mRNA and protein levels of TLR2， MyD88， NF-κB， NLRP3， and Caspase-1 （P<0.01）. Compared with the model group， the high- and medium-dose modified Dingjingtang groups showed significant improving effects regarding the above indicators （P<0.05， P<0.01）. ConclusionModified Dingjingtang can ameliorate the inflammatory skin lesions in the rat model of acne by regulating the TLR2/NF-κB/NLRP3 signaling pathway.

Objective To observe the clinical efficacy of Yinlian Gargle in the treatment of acute radiation-induced oropharyngeal mucositis after nasopharyngeal carcinoma radiotherapy.Methods Thirty-two patients with nasopharyngeal carcinoma,who had received first radiation,were randomly split into two groups:the trial group(19 cases)and the control group(13 cases).After all groups were treated with radiotherapy and chemotherapy,the control group was given rinse treatment with saline whereas the trial group was given Yinlian Gargle.The incidence of severe acute radiation-induced oropharyngeal mucositis,the duration and intensity of oropharyngeal discomfort and pain(NRS score),quality of life(QOL-NPC score),duration and intensity of radiation-induced side effects(SE-QOL-NPC score)and symptoms of dry mouth(SE1 score)were monitored before and after intervention in two groups.Results The incidence of grade Ⅲ or above radiation-induced oropharyngeal mucositis until the sixth week of radiotherapy in the trial group was considerably lower than that in the control group(P＜0.001),while the incidence of grade I or above radiation-induced oropharyngeal mucositis at 1 month after radiotherapy in the trial group was obviously lower than that in the control group(P＜0.001).The NRS score of pharyngeal discomfort of the trial group was lower than that of the control group starting from the second week of radiotherapy(P＜0.05).The NRS score of oral and oropharyngeal pain was lower than that of the control group starting from the fourth week of radiotherapy(P＜0.05).The SE1 score of the trial group was higher than that of the control group starting from the fifth week of radiotherapy(P＜0.05).After one month of the completion of the radiotherapy,the NRS score of pharyngeal discomfort and the NRS score of oral and oropharyngeal pain in the trial group were lower than those of the control group(P＜0.001).The QOL-NPC score,SE-QOL-NPC score,and SE1 score were all higher than those in the control group(P = 0.05 or P＜0.05).Conclusion Patients with nasopharyngeal cancer can greatly reduce their risk of developing severe acute radiation-induced oropharyngeal mucositis,effectively delay and relieve related symptoms,and enhance quality of life by consistently using Yinlian Gargle during radiotherapy.Additionally,a month after the completion of radiotherapy,it still has positive therapeutic effects on acute radiation-induced oropharyngeal mucositis.

To summarize Professor AI Rudi's experience in the staged external treatment of eczema by traditional Chinese medicine （TCM）. It is believed that dampness is the key pathological factor of eczema， and the treatment for dampness should be carried out throughout the whole process， with the leading idea of “three-stage treatment， dampness as the root， and treatment according to the symptoms”. The preparation and formulas of the external treatment can be applied according to the pathogenesis and lesion characteristics of each stage. In acute stage with wind-dampness and heat in the skin as the main mechanism， the treatment is to clear heat and astringe， resolve toxins and relieve itching， and the preparation is mostly solution and lotion， and the formula could be Yangzheng Xi Formula （痒症洗方）， Jingfang Kushen Decoction （荆防苦参汤）， Kuding Erhuang Decoction （苦丁二黄汤）， and Xianglian Jinhuang Powder （香连金黄散）. In subacute stage with phlegm-dampness and heat as the main mechanism， the treatment is to remove dampness and turbidity， clean up the residual heat； the preparation is mostly ointment， and the formula include Shehuang Ointment （蛇黄软膏）， Huanglian Ointment （黄连膏）， and Zihuan Diding Ointment （紫花地丁软膏）. In chronic stage with phlegm-dampness stagnation as the main mechanism， the treatment is to remove dampness and eliminate phlegm， remove blood stasis and stop itching， and the formula could be Zhiyang soft Ointment （止痒软膏）， Runji Ointment （润肌膏）， Yufu Ointment （愈肤膏）； jojoba oil and olive oil are often used as external moisturiser for daily care.

【Objective】 To explore the effects of finasteride on the gene expression in patients with benign prostatic hyperplasia (BPH) through transcriptome analysis. 【Methods】 Postoperative prostate tissues from patients who underwent prostatectomy at Peking University Third Hospital during Oct.2020 and Oct.2021 were collected.The patients were divided into medication group and non-medication group based on whether they had taken finasteride for a long time before surgery, with 8 patients in either groups.Transcriptome sequencing analysis was performed and the results were validated with qPCR and immunohistochemistry analysis. 【Results】 Compared with the non-medication group, 857 up-regulated and 806 down-regulated genes were screened in the medication group.Pathway enrichment analysis showed that finasteride induced down-regulation of vascular endothelial growth factor D (VEGFD) expression in the focal adhesion pathway.Inter group network analysis suggested that the calcium signaling pathway was key in the entire process.GSEA enrichment analysis further revealed the up regulation of CD38 gene expression in the calcium signaling pathway.The qPCR and immunohistochemistry analysis supported the transcriptome results mentioned above, and found that androgen receptor (AR) expression was also increased. 【Conclusion】 Finasteride reduces prostate microvascular formation by downregulating the expression of VEGFD in the focal adhesion pathway, thereby reducing the risk of bleeding during prostate hyperplasia surgery. Long-term use of finasteride leads to the up regulation of CD38 expression in the calcium signaling pathway, which may lead to the development of finasteride resistance.

ObjectiveTo observe the effect of Youguiwan on the leptin/Janus kinase 2 （JAK2）/signal transducer and activator of transcription 3 （STAT3） signaling pathway in the lung tissue of the rat model of chronic obstructive pulmonary disease （COPD） due to kidney-Yang deficiency. MethodForty rats were modeled for COPD with the syndrome of kidney-Yang deficiency by intratracheal instillation of lipopolysaccharide on day 1 and day 14 and continuous fumigation for 6 weeks， during which hydrocortisone was injected intramuscularly at an interval of 3 days. The modeled rats were randomized into model， high- （11.7 g·kg^-1）， medium- （5.85 g·kg^-1）， and low-dose （2.93 g·kg^-1） Youguiwan， and aminophylline （0.054 g·kg^-1） group. In addition， 8 SD rats were set as the blank group. After the completion of modeling， the rats in each group were administrated with the corresponding drug by gavage for 28 consecutive days. After the last administration， samples were collected. A lung function analyzer was used to evaluate the lung function of rats. Enzyme-linked immunosorbent assay was employed to measure the levels of interleukin-17A （IL-17A）， interleukin-6 （IL-6）， and tumor necrosis factor-α （TNF-α） in the bronchoalveolar lavage fluid （BALF）. Hematoxylin-eosin staining was employed to observe the pathological changes in the lung tissue， and Masson staining was employed to observe the deposition of blue collagen fibers around bronchi in the lung tissue and calculate the inflammation score. The immunofluorescence assay was employed to measure the protein content of collagen type Ⅰ （ColⅠ） and α-smooth muscle actin （α-SMA） in the bronchi. The protein and mRNA levels of leptin， IL-17A， JAK2， and STAT3 in the lung tissue were determined by Western blot and real-time fluorescence quantitative polymerase chain reaction， respectively. ResultCompared with the blank group， the model group showed decreased lung function （P<0.01）， elevated levels of IL-6， IL-17A， and TNF-α in the BALF （P<0.01）， and increased lung inflammation score， deposition of subcutaneous collagen fibers in the airway， and ColⅠ and α-SMA proteins （P<0.01）. Furthermore， the modeling up-regulated the proteins and mRNA levels of leptin， IL-17A， JAK2， and STAT3 in the lung tissue （P<0.01） and enhanced the phosphorylation of JAK2 and STAT3 （P<0.01）. Compared with the model group， high- and medium-dose Youguiwan improved the lung function， decreased the inflammation score， reduced collagen fiber deposition and ColⅠ and α-SMA proteins， lowered the levels of IL-6， IL-17A， and TNF-α in the BALF， down-regulated the mRNA and protein levels of leptin， JAK2， STAT3， and IL-17A， and weakened the phosphorylation of JAK2 and STAT3 （P<0.05， P<0.01）. The aminophylline group had higher IL-17A and TNF-α levels than the high-dose Youguiwan group， lower IL-17A level than the medium and low-dose Youguiwan groups， and lower TNF-α level than the low-dose Youguiwan group. Compared with the aminophylline group， the high- and medium-dose Youguiwan groups showed reduced deposition of collagen fibers and protein levels of ColⅠ and α-SMA around the bronchi in the lung tissue （P<0.05， P<0.01）， decreased inflammation score， and down-regulated protein and mRNA levels of leptin， JAK2， STAT3， and IL-17A in the lung tissue. ConclusionYouguiwan can prevent airway remodeling by inhibiting IL-17A to reduce inflammation and collagen deposition in COPD rats， which may be related to the inhibition of the leptin/JAK2/STAT3 signaling pathway.

OBJECTIVE: To evaluate the effect of manual acupuncture on endometrial blood flow parameters by three-dimensional (3D) power Doppler ultrasound in women undergoing in vitro fertilization embryo transfer (IVF-ET). METHODS: Seventy patients undergoing IVF-ET were equally randomized into traditional or sham acupuncture treatment group for totally 4 days (from the day of oocyte aspiration to the day of embryo transfer) of treatment by random envelope method at the Reproductive Medicine Center and Outpatient Department of Integrated Traditional Chinese and Western Medicine, Tongji Hospital, Tongji Medicine College, Huazhong University of Science and Technology from January 2013 to December 2015. Patients in the traditional acupuncture group accepted traditional acupuncture methods with manual acupuncture, and Zhongji (CV3), Qihai (CV 6), Sanyinjiao (SP6), Taichong (LR 3), Tianshu (ST 25), Guilai (ST 29) and Zusanli (ST 36) were chosen. Patients at the sham acupuncture group accepted shallow acupuncture methods at 4 non-meridian points at each shoulder and upper arm. Outcome measures included endometrial ultrasonic indices such as vascularization index (VI), flow index (FI) and vascularization flow index (VFI), endometrial thickness and volume, subendometrial VI (sVI), subendometrial FI (sFI), subendometrial VFI (sVFI), implantation rate, clinical pregnancy rate, abortion rate, live birth rate and number of live births. RESULTS: Finally, 34 patients in the traditional acupuncture group and 35 in the sham acupuncture group completed this trial. VI, FI and VFI of the traditional acupuncture group were significantly higher than those in the sham acupuncture group (P<0.05). No significant differences were found in endometrial thickness, endometrial volume, sVI, sFI, sVFI, implantation rate, clinical pregnancy rate, abortion rate, live birth rate and number of live births (P>0.05). CONCLUSIONS Manual acupuncture performed after oocyte aspiration and before transplantation improved the endometrial blood flow parameters VI, RI and VFI in women who underwent IVF-ET, instead of sVI, sFI and sVFI. Therefore, acupuncture might be beneficial in women undergoing IVF-ET by increasing endometrial blood flow and endometrial receptivity. (Registration No. ChiCTR2100053354).

Objective:To investigate the current situation of the use of transjugular intrahepatic portosystemic shunt (TIPS) for portal hypertension, which should aid the development of TIPS in China.Methods:The China Portal Hypertension Alliance (CHESS) initiated this study that comprehensively investigated the basic situation of TIPS for portal hypertension in China through network research. The survey included the following: the number of surgical cases, main indications, the development of Early-TIPS, TIPS for portal vein cavernous transformation, collateral circulation embolization, intraoperative portal pressure gradient measurement, commonly used stent types, conventional anticoagulation and time, postoperative follow-up, obstacles, and the application of domestic instruments.Results:According to the survey, a total of 13 527 TIPS operations were carried out in 545 hospitals participating in the survey in 2021, and 94.1% of the hospital had the habit of routine follow-up after TIPS. Most hospitals believed that the main indications of TIPS were the control of acute bleeding (42.6%) and the prevention of rebleeding (40.7%). 48.1% of the teams carried out early or priority TIPS, 53.0% of the teams carried out TIPS for the cavernous transformation of the portal vein, and 81.0% chose routine embolization of collateral circulation during operation. Most of them used coils and biological glue as embolic materials, and 78.5% of the team routinely performed intraoperative portal pressure gradient measurements. In selecting TIPS stents, 57.1% of the hospitals woulel choose Viator-specific stents, 57.2% woulel choose conventional anticoagulation after TIPS, and the duration of anticoagulation was between 3-6 months (55.4%). The limitation of TIPS surgery was mainly due to cost (72.3%) and insufficient understanding of doctors in related departments (77.4%). Most teams accepted the domestic instruments used in TIPS (92.7%).Conclusions:This survey shows that TIPS treatment is an essential part of treating portal hypertension in China. The total number of TIPS cases is far from that of patients with portal hypertension. In the future, it is still necessary to popularize TIPS technology and further standardize surgical indications, routine operations, and instrument application.
