ObjectiveTo investigate the mechanisms by which Mahuang Lianqiao Chixiaodoutang (MLC) improves obesity-type polycystic ovary syndrome (PCOS) through the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway. MethodsThirty-six female Sprague-Dawley (SD) rats were randomly divided into a blank control group (Con) and an obesity-type PCOS model preparation group. The model was induced by gavage with letrozole (1 mg·kg-1) combined with a high-fat diet (HFD). After model establishment, the obesity-type PCOS model preparation group was further divided into the model group (Mod, normal saline), metformin group (Met, 0.3 g·kg-1), low-dose MLC group (MLC-L, 4.3 g·kg-1), medium-dose MLC group (MLC-M, 8.6 g·kg-1), and high-dose MLC group (MLC-H, 17.2 g·kg-1). Active components of MLC and targets of obesity-type PCOS were screened from databases, a protein-protein interaction (PPI) network was constructed, and gene ontology(GO)and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis was performed. The gut microbiota structure was analyzed based on 16S rRNA sequencing and correlated with network pharmacology pathways. Body weight and estrous cycle were dynamically monitored. Ovarian morphology was observed by hematoxylin-eosin (HE) staining. Cell apoptosis was detected by terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL). Enzyme-linked immunosorbent assay (ELISA) was used to detect levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), anti-Müllerian hormone (AMH), testosterone (T), and estradiol (E2). Western blot was used to detect the protein expression levels of phosphorylated PI3K/PI3K (p-PI3K/PI3K), phosphorylated Akt/Akt (p-Akt/Akt), B-cell lymphoma-2 (Bcl-2), and Bcl-2-associated X protein (Bax). ResultsNetwork pharmacology screening identified 124 active components of MLC and 408 overlapping targets between the herbal formula and the disease. Core targets such as Akt1 and Bcl-2 were revealed. As indicated by 16S rRNA sequencing, the abundances of Lachnospiraceae, Lachnoclostridium, and Dorea were increased in the MLC groups (P<0.05), while the abundance of Veillonella was decreased (P<0.05). KEGG correlation analysis integrating network pharmacology and gut microbiota data showed significant enrichment of the PI3K/Akt signaling pathway. Animal experiments showed that, compared with the Mod group, body weight decreased to normal levels in the Met, MLC-M, and MLC-H groups. The estrous cycle became regular. The number of corpora lutea increased and cystic follicles decreased. Serum levels of T, FSH, and LH/FSH were reduced (P<0.05, P<0.01), while the E2 level was increased (P<0.01). Ovarian cell apoptosis was reduced (P<0.01), and the protein expression levels of p-PI3K/PI3K, p-Akt/Akt, and Bcl-2 in ovarian tissue were significantly increased, whereas Bax protein expression was significantly decreased (P<0.05, P<0.01). ConclusionMLC can regulate gut microbiota structure, effectively improve ovarian pathology in rats with obesity-type PCOS, and inhibit ovarian granulosa cell apoptosis. The mechanism may be associated with upregulation of the PI3K/Akt signaling pathway.

Objective:To investigate the efficacy of endoscopic sclerotherapy for internal hemorrhoids and its effects on patients' bowel function.Methods:A total of 111 patients who received endoscopic sclerotherapy at Xi'an No. 3 Hospital from September 2019 to August 2020 were retrospectively included in this study. Clinical efficacy, postoperative complications, perianal discomfort, and abnormal defecation were compared among patients with grade Ⅰ, Ⅱ, and Ⅲ internal hemorrhoids at 1, 4, 8, 12 weeks, and 6 months after surgery.Results:After 6 months of follow-up, the overall response rate was 77.48% (86/111), and the cure rate was 77.17% (79/111). The response rate and cure rate for rectal bleeding were 83.75% (67/80) and 80.00% (64/80), respectively. The response rate and cure rate for prolapse were 82.46% (47/57) and 75.44% (43/57), respectively. There were no statistically significant differences in the response rates and cure rates for rectal bleeding and prolapse symptoms among patients with grade Ⅰ, Ⅱ, and Ⅲ internal hemorrhoids at each follow-up time point (all P>0.05). Among the 111 patients, 27.93% (31/111) experienced perianal discomfort, and 40.54% (45/111) reported abnormal defecation. The incidences of perianal discomfort and abnormal defecation were not statistically significant among patients with grade Ⅰ, Ⅱ, and Ⅲ internal hemorrhoids (both P>0.05). In patients with gradeⅠ and Ⅱ internal hemorrhoids, perianal discomfort symptoms began to improve 4 weeks after surgery, while symptoms of abnormal defecation started to improve 1 week after surgery. Conclusions:Endoscopic sclerotherapy has a good clinical efficacy for rectal bleeding and prolapse symptoms in patients with grade Ⅰ, Ⅱ, and Ⅲ internal hemorrhoids. Additionally, it improves perianal discomfort and abnormal defecation by identifying the anal canal transition zone in patients with internal hemorrhoids.
