Mulberry and Hippophae-based solid beverage promotes weight loss in rats by antagonizing white adipose tissue PPARγ and FGFR1 signaling.

Obesity, a multifactorial disease with many complications, has become a global epidemic. Weight management, including dietary supplementation, has been confirmed to provide relevant health benefits. However, experimental evidence and mechanistic elucidation of dietary supplements in this regard are limited. Here, the weight loss efficacy of MHP, a commercial solid beverage consisting of mulberry leaf aqueous extract and Hippophae protein peptides, was evaluated in a high-fat high-fructose (HFF) diet-induced rat model of obesity. Body component analysis and histopathologic examination confirmed that MHP was effective to facilitate weight loss and adiposity decrease. Pathway enrichment analysis with differential metabolites generated by serum metabolomic profiling suggests that PPAR signal pathway was significantly altered when the rats were challenged by HFF diet but it was rectified after MHP intervention. RNA-Seq based transcriptome data also indicates that MHP intervention rectified the alterations of white adipose tissue mRNA expressions in HFF-induced obese rats. Integrated omics reveals that the efficacy of MHP against obesogenic adipogenesis was potentially associated with its regulation of PPARγ and FGFR1 signaling pathway. Collectively, our findings suggest that MHP could improve obesity, providing an insight into the use of MHP in body weight management.

[Studies on the chemical constituents from Daphne tangutica].

OBJECTIVE: To research the chemical constituents from Daphne tangutica. METHODS: Column chromatography with silica gel, ODS-C18, Sephadex LH-20 and re-crystallization were employed to isolate and purify the constituents. According to physical and chemical properties and spectral data to identify the structure of compounds. RESULTS: Eight compounds were isolated and identified as palmitic acid (1), laurostearic acid(2), beta-sitosterol(3), 7-methoxy-8-hydroxycumarin(4), daphnetin(5), genkwanin(6), hydroxygenkwanin(7), p-hydroxybenzoic acid(8). CONCLUSION: Compounds 1,2,7 and 8 are isolated from Daphne tangutica for the first time.

Concurrence of Multiple Cutaneous Malignancies on Sun-exposed Vitiligo Skin of a Patient: A Case Report and Review of the Literature.

There are very few published studies in the literature examining the association between vitiligo and skin cancers and only some anecdotal reports about phototherapy-associated nonmelanoma skin carcinoma (NMSC) in patients with vitiligo. Herein, we report a case of an 84-year-old male with widespread vitiligo with concurrent onset of two primary cutaneous malignancies in sun-exposed vitiligo skin. The association between vitiligo and NMSC deserves further assessment. Chronic sun damage might be a possible causative factor for the development of NMSC in the vitiligo patient.
