Effect of Taoren Quyu Decoction on human endometrial cells and its anti-endometriosis activity in rats

Objective: To study the effect of Taoren Quyu Decoction (TQD) on endometrial cells in patients with endometriosis (EMs) and EMs in rats. Methods: A total of 60 female Wistar rats were randomly divided into 4 groups, namely, normal group, model group, positive group and TQD group, each group having 15 rats. Except the normal group, EMs model was established in the other three groups by transplanting the rat autologous endometrium. After 4 weeks of intragastric administration, blood, eutopic and ectopic endometrial tissues of rats in each group were collected to detect the serum levels of estrogen (E2), cancer antigen 125 (CA125), endometrial antibody (EMA13), and expressions of microvessel density (MVD), vascular endothelial growth factor (VEGF) and angiopoietin (Ang-2). The volume of endometriosis cyst was determined simultaneously. For the in vitro culture of human endometrial cells, 4 groups, namely, normal group, model group, positive group and TQD group were used. The positive group and TQD group were treated with danazol and TQD respectively. Then 24 h after the treatment, the expressions of survivin and tumor suppressor gene (p53) of each group were detected. Results: The volumes of the endometriosis cysts in the positive group and the TQD group were significantly reduced compared with the model group (P<0.05). The serum levels of E2, CA125 and EMAb, and the expressions of MVD. VEGF and Ang-2 in the model group were significantly increased compared with the normal group (P<0.0.5): while they were all significantly reduced in the positive group and TQD group (P<0.05). Compared with the normal group, the expression of survivin in the model group was significantly up regulated (/1/40.05), and expression of p53 was significantly reduced (P<0.05); compared with the model group, the expressions of survivin in the positive and TQD groups were significantly decreased (P<0.05), and expression of p53 was significantly up-regulated (P<0.05). The difference between positive group and TQD group was not statistically significant (P>0.05). Conclusions: TQD has a significant anti-EMs effect, and its mechanism of action may be related to anti-angiogenesis and promoting apoptosis of ectopic endometrial cell.

AIM： To explore the expression of phosphatase and tensin homolog deleted on chromosome ten （PTEN） in liver of athymic mice with hepatocellular carcinoma （HCC） and the effect of Fuzheng Jiedu Decoction （FJD）. METHODS： Forty eight male BALB/c athymic mice models were built by Bel-7402 with an indirect method. After 24 h of postoperation, the 48 athymic mice were distributed randomly into 4 groups： A, B, C, D, each group had 12 athymic mice. Group A were were treated by intragastric administration with FT207 （Tegafur） for 4 wk. Group B, C and D were treated by intragastric administration with FJD （complex prescription of Chinese crude drug） that had been delegated into 3 kinds of density as the low, middle, and high for 4 wk. At last, athymic mice were put to death, live time, volume of tumors, exponent of tumors and the tumor metastasis in livers were observed; and PTEN was detected in hepatic tissue, latero-cancer tissue and cancer tissue by immunohistochemistry. RESULTS： Four weeks later, the total survival rate in treatment group （A ＋ B ＋ C） was 50% and higher than the control group （0%） treated by FT207, （P 〈 0.01）. The survival rate in group A, B, C was higher than in group D, and except group A with D, there was significant differentces （Fisher＇s Exact Test P = 0.05 or 0.01）. And no differences were observed between the treatment groups and the control group in volume of tumors and exponent of tumors （P 〉 0.05）. Tumor metastasis in livers of the treatment group was less than the controls （Fisher＇s Exact Test, P = 0.021）. The result of immunohistochemistry showed that the intensity of PTEN in latero-cancer tissue was the highest, and then the hepatic tissue, the lowest was cancer tissue （Kruskal- Wallis test, X^2 = 60.67, P = 0.000）. It also showed that the intensity of PTEN in treatment groups （A, B, C） was higher than the control group （D） （F = 5.90, P = 0.002 in hepatic tissue and F = 15.99, P = 0.000 in latero-cancer tissue and X^2 = 26.08, P = 0.000 in cancer tissue）, and group B is the highest in the treatment groups （P 〈 0.05, r = 0.01. respectively）. However, there was no significant statistic difference between group A and group C （P 〉 0.05）. CONCLUSION： FJD can prolong the survival time and decrease tumor metastasis in livers of these experimental mice. Mechanisms of FJD healing HCC may partially be explained by enhancing the expression of PTEN in liver.

Effect of Huanglian Jiedu Decoction on cardiac endoplasmic reticulum stress in spontaneously hypertensive rats

Huanglian Jiedu Decoction(HLJDD)is a quintessential prescription renowned for its heat-clearing and detoxifying properties.It is primarily prescribed to counteract the syndrome characterized by the excessive heat of the Sanjiao fire.Notably,the hyperactivity of liver fire is frequently linked with hypertension,where wind fire and wind toxicity emerge as pivotal pathogenic factors.This study aimed to investigate the impact of HLJDD on the endoplasmic reticulum in spontaneously hypertensive rats(SHR),further delving into the interplay between endoplasmic reticulum stress(ERS)and myocardial remodeling and damage.Fifty SHR rats were stratified randomly into five cohorts:model,low-dose HLJDD,medium-dose HLJDD,high-dose HLJDD,and captopril groups.For comparison,a set of Wistar-Kyoto(WKY)rats served as the baseline control group,with each group comprising 10 rats.While the model and control groups received equivalent volumes of normal saline via gavage,the other groups were administered the respective drug dosages through the same route daily for a span of 6 weeks.Upon the experiment’s conclusion,metrics such as the heart mass index(HWI)and left ventricular mass index(LVWI)were assessed.Cardiac tissue anomalies were identified using H&E staining,while ERS-related protein and mRNA expression levels were ascertained via Western blotting analysis and qPCR.Moreover,TUNEL staining was employed to detect cardiomyocyte apoptosis.The findings indicated that increasing HLJDD concentrations corresponded with escalated HWI and LVWI in rat hearts(P<0.05).There was a marked enhancement in myocardial structural integrity,accompanied by a notable reduction in collagen fibers.The mRNA and protein expressions of myocardial inositol-dependent enzyme 1α(IRE1α),X-box binding protein 1(XBP1),glycoregulatory protein 78(GRP78),and CCAAT enhancer binding protein homologous protein(CHOP)in the medium and high-dose groups saw significant declines(P<0.05).These effects mirrored those observed in the captopril group.The study underscored HLJDD’s efficacy in mitigating myocardial tissue damage in SHR.This therapeutic effect was potentially attributed to the downregulation of IRE1α,XBP1,GRP78,and CHOP,curbing excessive ERS,diminishing cardiomyocyte apoptosis,and thereby conferring cardioprotection.
