Role of Wnt/β-catenin Signaling Pathway in Seborrheic Alopecia and Its Intervention with Traditional Chinese Medicine： A Review / 中国实验方剂学杂志

Seborrheic alopecia is a chronic dermatological disease caused by multiple factors. It occurs frequently in young and middle-aged men aged 20-30 years. The main clinical manifestations are greasy hair， itching， excessive dandruff， receding hairline， sparse hair on the top of the head， and progressive hair loss in the frontotemporal area. Seborrheic alopecia is not fatal， but it affects the appearance of patients， seriously harming their self-esteem and bringing great psychological distress to them. The Wnt/β-catenin signaling pathway widely exists in multicellular eukaryotes and is a basic growth regulatory pathway which regulates cell proliferation and differentiation， maintains stem cells activity and organ homeostasis， and affects cell migration. At present， it has been reported in China and abroad that Wnt/β-catenin signaling pathway is closely related to the occurrence and development of seborrheic alopecia and the action mechanism of drugs. Traditional Chinese medicine （TCM） has multi-component， multi-target， and multi-pathway advantages， and it can promote the formation of hair follicle laminae， the proliferation and differentiation of hair follicle stem cells， and the periodic changes in hair follicles by regulating the Wnt/β-catenin signaling pathway， thereby alleviating seborrheic alopecia. This article reviewed the relationship of Wnt/β-catenin signaling pathway and its key target protein factors with seborrheic alopecia to clarify the important role of Wnt/β-catenin signaling pathway in seborrheic alopecia. At the same time， the TCM that targeted the Wnt/β-catenin signaling pathway to relieve seborrheic alopecia were summarized， so as to provide reference for the treatment of seborrheic alopecia and further development of new drugs.

Clinical study on Qinghouyan lozenge in treatment of acute pharyngitis / 中国中药杂志

To evaluate the clinical efficacy and safety of Qinghouyan lozenge in the treatment of acute pharyngitis due to Lung-heat and Yin-deficiency, and compare with Qinghouyan oral Liquid. Totally 144 subjects were enrolled and randomly divided into two groups (72 in the test group and 72 in the control group). The participants in the test group were given Qinghouyan lozenge for 5 days, and those in the control group were given Qinghouyan oral Liquid for 5 days. The effectiveness evaluation indexes were pharyngalgia/odynophagia disappearance rate, overall efficacy of TCM syndromes, TCM syndrome scores, and single syndrome and sign disappearance rate. During the test, the safety was evaluated by vital sign, lab examination indexes and adverse events. The results for the full analysis set showed that the couth disappearance rate, the incidence rate of TCM syndromes, and the throat/uvula congestion disappearance rate of the test group were higher than that of the control group (P < 0.05), with significant differences in the changes in syndrome scores between the two groups (P < 0.05). Altogether 3 adverse events were observed in the test group while 6 adverse events in the control group, without significant differences in the adverse event rate between the two groups (P < 0.05), serious abnormal laboratory examinations and vital signs. In conclusion, Qinghouyan lozenge has better efficacy in treatment of acute pharyngitis due to Lung-heat and Yin-deficiency than Qinghouyan oral liquid, with good safety.

Effects of Shujing Ketong soft capsules on uterine activity of animals / 中国中药杂志

<p><b>OBJECTIVE</b>To observe effects of Shujing Ketong soft capsules (SJKTSC) on activities of the uterine of the rat in vitro and in vivo.</p><p><b>METHOD</b>The isolated rat uterine were mounted in the improved Genell solution with a final content of 0. 96, 1.92, 3.84 microg x g(-1) of SJKTSC at 37 degrees C; and 9. 6, 19. 2, 38.4 mg x kg(-1) of SJKTSC and 2 g x kg(-1) of Tongjingbao granules were given to the rat through the duodenum respectively. Their effects on frequency, amplitude and activity of contraction of rat uterus in vitro and in vivo were investigated.</p><p><b>RESULT</b>SJKTSC could significantly inhibit the frequency, amplitude and activity of contraction of the normal rat uterus in vitro and decrease the oxytocin-induced increase of contraction of the rat uterus in vitro; lowered the frequency, amplitude and activity of the oxytocin-induced contraction of the rat uterus in vivo and inhibit the oxytocin-induced the strengthening of contraction of the rat uterus in vivo.</p><p><b>CONCLUSION</b>Shujing Ketong soft capsules maybe used for treatment of dysmenorrhea induced by spasm of uterine smooth muscle.</p>
