Therapeutic Potential of Thunbergia laurifolia L. Extract in Gestational Diabetes Mellitus: Insights from a Rat Model

OBJECTIVE

To assess the effects of Thunbergia laurifolia L. extract (TLE) on gestational diabetes mellitus (GDM) in a rat model.

METHODS

Thunbergia laurifolin L. leaves were subjected to ethanolic extraction. In vivo study, 50 pregnant rats were randomly divided into 5 groups (10 for each): non-GDM group, GDM induced by streptozotocin (STZ, 60 mg/kg i.p.), metformin (MET) 100 mg/kg, TLE 50, and 500 mg/kg groups. Administration was performed on gestation day 7 until term (day 21). The effects of TLE on blood glucose, insulin levels, lipid profiles, liver enzymes, and maternal performances were assessed. In in vitro study, the effect of TLE was examined using the organ bath for uterine force measurement.

RESULTS

In in vivo study, TLE significantly reduced blood glucose as compared to GDM (P<0.05) with gradually increased insulin level. This effect was consistent with islets of Langerhans restoration. Histologically, the uterine muscular layer displayed a marked increase in fiber area in response to both doses as compared to GDM (P<0.05). Additionally, TLE significantly reduced total cholesterol, triglyceride, and alanine transaminase levels (P<0.05). Intriguingly, TLE also led to a notable augmentation in gravid uterus size, live fetuses count, and implantation numbers, while significantly reducing the post-implantation loss rate associated with fetal classification (P<0.05). Thus, GDM improvements were close to those produced by MET. In in vitro study, TLE exerted a concentration-dependent inhibition of spontaneous uterine contractility (half-maximal inhibition concentration=1.2 mg/L). This inhibitory effect extended to potassium chloride depolarization and oxytocin-mediated contractions. When combined with its major constituent, rosmarinic acid, TLE produced an enhanced inhibitory effect (P<0.05).

CONCLUSIONS

TLE ameliorated blood glucose levels, enhanced uterine muscular structure, and improved maternal and fetal performance in GDM. TLE also displayed tocolytic properties. These findings underscore the need for further exploration of TLE as a potential tocolytic agent to mitigate GDM-associated complications.

Ethnopharmacology of five flowers herbal tea, a popular traditional beverage in Hong Kong and South China

BACKGROUND

It has been a long-standing tradition of using herbal tea for preventive and therapeutic healthcare in Hong Kong and South China and Five Flowers Tea is one of the most popular herbal teas. Based on the principle of traditional Chinese medicine, the pharmacological functions are to clear heat and dispel dampness in the body. Heat and dampness are thought to contribute to a range of health problems, especially during the hot and humid season in South China and Hong Kong. The most prevalent herbs in the formula contain bioactive compounds including flavonoids, alkaloids and terpenoids, which have a wide range of pharmacological properties including anti-inflammation, antivirus, antidiarrhoea, antibacteria, and antioxidation. However, with the composition varies widely, the ethnopharmacological benefits described may not be delivered uniformly. This study is to provide a comprehensive analysis on the composition of the Five Flowers Tea sold in Hong Kong and investigate the rationale behind the selection of herbs used in the formula. This study also provides information on the variation and quality of the Five Flowers Tea in the market.

METHODS

Thirty-three Five Flowers Tea samples were collected from various locations in Hong Kong. The size, texture, colour and organoleptic properties were documented. Macroscopic and molecular authentication methods were employed to identify the individual components.

RESULTS

Macroscopic identification revealed there were 23 herbs belonging to 18 plant families. The most prevalent herb was Bombax ceiba L., followed by Chrysanthemum morifolium. Ten adulterants and the existence of insect Lasioderma serricorne were confirmed by DNA barcoding techniques.

CONCLUSION

This study employed a comprehensive approach to authenticate the herbs in Five Flowers Tea samples collected from various locations in Hong Kong. Macroscopic and molecular methods were used to identify the herbs and adulterants. The findings revealed the varied composition in Five Flowers Tea and the occurrence of adulterants in some samples. This shows that quality assurance of Five Flowers Tea is essential for the effective use of this popular folk medicine.

Albiflorin Alleviates Sepsis-induced Acute Liver Injury through mTOR/p70S6K Pathway

BACKGROUND

Sepsis often induces hepatic dysfunction and inflammation, accounting for a significant increase in the incidence and mortality rates. To this end, albiflorin (AF) has garnered enormous interest due to its potent anti-inflammatory activity. However, the substantial effect of AF on sepsis-mediated acute liver injury (ALI), along with its potential mechanism of action, remains to be explored.

METHODS

An LPS-mediated primary hepatocyte injury cell model in vitro and a mouse model of CLP-mediated sepsis in vivo were initially built to explore the effect of AF on sepsis. Furthermore, the hepatocyte proliferation by CCK-8 assay in vitro and animal survival analyses in vivo for the survival time of mice were carried out to determine an appropriate concentration of AF. Then, flow cytometry, Western blot (WB), and TUNEL staining analyses were performed to investigate the effect of AF on the apoptosis of hepatocytes. Moreover, the expressions of various inflammatory factors by ELISA and RT-qPCR analyses and oxidative stress by ROS, MDA, and SOD assays were determined. Finally, the potential mechanism of AF alleviating the sepsis-mediated ALI via the mTOR/p70S6K pathway was explored through WB analysis.

RESULTS

AF treatment showed a significant increase in the viability of LPS-inhibited mouse primary hepatocytes cells. Moreover, the animal survival analyses of the CLP model mice group indicated a shorter survival time than the CLP+AF group. AF-treated groups showed significantly decreased hepatocyte apoptosis, inflammatory factors, and oxidative stress. Finally, AF exerted an effect by suppressing the mTOR/p70S6K pathway.

CONCLUSION

In summary, these findings demonstrated that AF could effectively alleviate sepsis-mediated ALI via the mTOR/p70S6K signaling pathway.

Effectiveness of Scutellaria baicalensis Georgi root in pregnancy-related diseases: A review

The root of Scutellaria baicalensis Georgi, also called Huangqin, is frequently used in traditional Chinese medicine. In ancient China, S. baicalensis root was used to clear heat, protect the fetus, and avoid a miscarriage for thousands of years. In modern times, pregnancy-related diseases can seriously affect maternal and fetal health, but few systematic studies have explored the mechanisms and potential targets of S. baicalensis root in the treatment of pregnancy-related diseases. Flavonoids (baicalein, wogonin and oroxylin A) and flavonoid glycosides (baicalin and wogonoside) are the main chemical components in the root of S. baicalensis. This study presents the current understanding of the major chemical components in the root of S. baicalensis, focusing on their traditional uses, potential therapeutic effects and ethnopharmacological relevance to pregnancy-related disorders. The mechanisms, potential targets and experimental models of S. baicalensis root for ameliorating pregnancy-related diseases, such as recurrent spontaneous abortion, preeclampsia, preterm birth, fetal growth restriction and gestational diabetes mellitus, are highlighted.

The Lived Experience of First-time Mothers with Congenital Heart Disease

PURPOSE

Nowadays most children with congenital heart disease (CHD) are expected to survive to adulthood. The healthcare focus needs to pay close attention to the important developmental tasks during their growth process. The women with CHD face some challenges in their critically developmental stages during pregnancy, delivery and even motherhood. The lived experience of being a mother need to be further concerned. This study aimed to explore the lived experience of first-time mothers with CHD.

METHODS

Descriptive phenomenological design was adopted. Semi-structured interviews were conducted from April-August 2018 with eleven primiparous women with CHD, who were recruited from the pediatric and adult cardiology outpatient departments at a medical center and who had a child aged between 6 months and 3 years. Giorgi's phenomenological analysis method was employed.

RESULTS

Six main themes arose from the analysis: (1) recognizing pregnancy risks, (2) performing self-care for health, (3) building self-worth from my baby, (4) adapting to postpartum life and adjusting priorities, (5) enjoying being a first-time mother, and (6) the factors contributing to success in high-risk childbirth.

CONCLUSIONS

The experiences that occurred prior to and after labor that were identified in this study can assist women with CHD to more capably prepare for and understand the process of becoming a mother, including recognition of the importance of a prepregnancy evaluation. The findings of this study can help women with CHD to better understand the path to becoming a mother, and prepare themselves for the challenges that lie ahead.
