In this study,the existing animal models of alopecia areata were systematically summarized based on literature review and disease and syndrome characteristics assignment method,and the clinical anastomosis was analyzed.The results showed that cell induction and skin transplantation had a high anastomosis with the clinic,and the anastomosis was as high as 80%.The anastomosis between imiquimod cream and cyclophosphamide induced alopecia areata was 72%.C3H/HeJ mice and C57BL/6 mice were selected as the first choice in terms of the pathogenesis of alopecia areata disease,pathogenic factors,replicability,convenience and practicability of the model.Other SCID mice,B6.KM-AA mice,SD rats and BALB/c mice can be selected appropriately according to the content and period of the experimental study of alopecia areata.It is found that the existing models of alopecia areata mainly rely on Western medicine,lack of pathogenic factors of traditional Chinese medicine,and the model of combining disease and syndrome of alopecia areata is not widely used in practice.Based on this,it is suggested that the animal model of"combination of disease and syndrome"should be considered in the subsequent construction of alopecia areata model to make it more suitable for clinical characteristics of disease and syndrome.We can add the relevant indicators of different syndrome types of liver and kidney insufficiency,blood stasis and maoqiao,blood deficiency and blood heat and other pathogenic factors,and add the apparent indicators of animal mental state,diet and water intake,behavior,etc.,to improve the animal model of alopecia areata which is highly consistent with the clinical characteristics of traditional Chinese and western medicine.

Objective:To evaluate the effects of cellulift ? administered intradermally by mesotherapy on collagen synthesis in D-galactose induced aging model of rats. Methods:The study was conducted between April and October in 2014 in the Department of Anatomy, Qindao University. 30 male rats were randomly allocated to three groups: aging treatment group, aging control group and normal group; each group had ten rats. Aging treatment group and the control group were subcutaneously injected with D-galactose prepared in saline 125 mg·kg -1·d -1 for 42 day. Normal group was injected with saline for 42 d with same method and dose. From the 18th day after shaving their hair, the dermis of two sides hip skin marked zone of aging treatment group were injected cellulift at a dose of 1 ml per week for 4 weeks. Meanwhile, the aging control group was administrated the same volume of saline with same method. In vivo skin collagen alterations were investigated by reflectance confocal microscopy 3 days after every treatment. Skin specimens were obtained in 42 days. In order to measure the dermal collagen density and dermal thickness, HE and Masson trichrome staining were performed, respectively. Immunohistochemical staining for TGFβ1 and proliferating cell nuclear antigen (PCNA) was performed. Also, the level of TGFβ1, Smad3, types Ⅰ and Ⅲ pro-collagen mRNA expression was assessed by real-time quantitative polymerase chain reaction. Results:As revealed by RCM, collagen density of aging treatment group increased gradually after treatments, while in aging control group it decreased with time. Measurement of dermal thickness, hydroxyproline content and TGFβ-1 mRNA and protein expression in treatment group increased significantly as compared with that in aging control group, but were significantly lower than that in normal group (F values were 25.45, 98.90, 37.94 and 21.35, respectively; P<0.05). Measurement of dermal collagen density, the mRNA expression of type I pre-collagen and Smad3 elevated over that of aging control group with significant difference (F values were 44.46, 29.54 and 10.01, respectively; P<0.05), and there was no difference between normal and aging treatment group ( P>0.05). The difference of PCNA expression between aging control and treatment groups was not significant ( P>0.05), and both were lower than normal group ( P<0.05) . Conclusions:Cellulift ? shows anti-aging effects by activating collagen synthesis and eventually causing dermal thickening. This effect is probably mediated by TGF-β1/Smad3 signaling pathway.

Objective:To explore the clinical efficacy of double opposing rhomboid flap in repairing facial skin defects.Methods:From January 2020 to December 2020, 30 cases of facial skin lesions were removed in the Department of Plastic and Aesthetic Surgery, the Affiliated Hospital of Qingdao University, including 12 males and 18 females, aged 14-65 years, with an average age of 34.2 years. The diameter of the facial skin defect wound was 0.5-2.0 cm. The patients with facial skin defect were repaired with double opposing rhomboid flap. All patients were followed up for 3-12 months.Results:The incisions of 30 patients were healed in one stage, and double opposing rhomboid flaps survived. Following-up for 3 to 12 months showed that the operation area was flat, the incision scar was not obvious, the texture and color of the operation area and the surrounding skin matched well, the surrounding organs were not deformed, the lesions were not recurrent, and the cosmetic effect was satisfactory.Conclusions:The double opposing rhomboid flap is an effective method to repair quasi-circular facial skin defects, which is worthy of clinical application.

Objective:To compare the postoperative effects of double eyelid surgery with different exophthalmos to find its influence on the surgery and necessary changes in preoperative design and during operation.Methods:A total of 50 female patients with single eyelid seeking beauty from June 2021 to March 2022 were selected from the Department of Plastic Surgery, Affiliated Hospital of Qingdao University. The ocular protrusion was measured by HETEL ophthalmostatometer before surgery. Both eyes at 12-15 mm were taken as normal group ( n=26), both eyes at 16-18 mm as mild protrusion group ( n=14) and both eyes at 19-22 mm as severe protrusion group ( n=10). All the patients were treated with double-eyelid surgery by orbital septum and unified postoperative nursing. Results:After six months of follow-up, there was no difference in eyelid width with closed eyes (all P>0.05). The width of double eyelid with open eyes in normal group was smaller than that in mild protrusion group ( F=23.23, all P<0.05), and the width of double eyelid with open eyes in mild protrusion group was smaller than that in severe protrusion group ( F=47.70, all P<0.05). There was no difference in the improvement rate of facial aesthetics among the three groups ( P>0.05). The " feeling of meet" and scar formation in the normal group were less than those in the mild protrusion group ( F=16.92, F=33.45, all P<0.05), and the " feeling of meet" and scar formation in the mild protrusion group were less than those in the severe protrusion group ( F=27.93, F=28.53, all P<0.05). The improvement rate of normal group was higher than that of mild and severe protrusion group (χ 2=7.25, 7.89, all P<0.05). There was no difference in the improvement rate between the mild and severe protrusion groups ( P>0.05). Conclusions:In clinical practice, it is necessary to make corresponding changes in the preoperative design and operation of double eyelid surgery for patients with high eyeball protrusion.

With high incidence and lethality rate and certain disability rate， tumor has become a major global public health threat. It has been verified that the occurrence and development of tumor are resulted from the synergy of environment， heredity， and gene mutation， involving the abnormal activation or inhibition of a variety of related pathways such as oxidative stress， inflammation， autophagy， and mesenchymal transition of cells. Among them， the excessive activation of inflammatory signaling pathway is one of the main mechanisms of carcinogenesis and tumor progression， which enhances the proliferation， chemoradiotherapy resistance， invasion， and metastasis of cancer cells. At the moment， the correlation between long-term chronic uncontrollable inflammation and "inflammation-cancer transformation" has been widely recognized. Therefore， it is of great significance for the prevention and treatment， diagnosis， and prognosis evaluation of tumor to clarify the role of inflammation in the incidence of tumor. Blockers or activators have been developed to target the corresponding inflammatory pathways. However， tumor is accompanied by the abnormality of multiple inflammatory pathways， especially the advanced tumor with metastasis of cancer cells， and thus the efficacy of single pathway-targeting agents is non-ideal. Chinese medicine， featuring multiple components and multiple targets， can remarkably control the inflammatory response， delay tumor progression， enhance the sensitivity of tumor cells to radiotherapy and chemotherapy， and reduce postoperative infection and the adverse reactions caused by radiotherapy and chemotherapy， thereby exerting the anti-cancer effect. Nevertheless， a few reports on the anti-tumor effect of Chinese medicine from the perspective of inflammation are available. Therefore， this paper mainly expounds the influence of inflammation on the occurrence and development of tumor and summarizes the research on the intervention of tumor by Chinese medicine through inflammatory pathway， which is expected to provide a new mindset for the prevention and treatment of tumor.

As the pace of society increases and lifestyles change， the incidence and mortality rates of breast cancer continue to rise. Targeted therapies are now promising in the treatment of breast cancer， and a variety of protein targets have been identified to play an important role in the development of breast cancer. Among them， signal transducer and activator of transcription （STAT） proteins constitute a crucial group that serves as important targets for transducing cellular transcriptional information， which can regulate downstream cell proliferation， apoptosis， cell migration， invasion， angiogenic factors， etc. and then affect the progression of breast cancer. The STAT family is closely associated with the inflammatory response to tumors and plays a landmark role in tumor development as well as in diagnosis and prognosis. The "inflammation-cancer" transformation refers to the process in which the inflammatory microenvironment caused by uncontrolled inflammation promotes normal cells to become cancerous. According to the theory of Chinese medicine， "heat toxicity" in "cancer toxicity" corresponds to inflammation， which is closely related to tumor development. As a major link associated with the inflammatory response， the STAT family has a promising role in the development and treatment of a variety of tumors， but its relevance to breast cancer remains inadequately explored. Chinese medicine has been shown to have good efficacy in the prevention and treatment of breast cancer， and some current studies have shown that the active ingredients and compounds of Chinese medicine have certain intervention effects on breast cancer-related STAT proteins， but there has not been a systematic review. In order to better sort out and summarize the studies on the effects of Chinese herbal medicines based on the STAT family interventions in breast cancer， this paper reviewed the studies on Chinese herbal medicines acting on the STAT family in recent years， aiming to provide new ideas for clinical applications in breast cancer and to provide thoughts for the development of STAT protein-based drugs.
