Antihypertensive Effects of Huotan Jiedu Tongluo in H-Type Hypertensive Rats

Hypertension, a major risk factor for heart attack, stroke, and renal failure, has become a significant public health challenge that affects 1 billion people worldwide1. Homocysteine (Hcy), a thiol group-containing amino acid, is a vital metabolic intermediary of methionine metabolism. Hypertension with elevated plasma Hcy levels is defined as H-type hypertension, which could be a significant risk factor for the occurrence and recurrence of cardiocerebrovascular diseases such as stroke2,3. Recent studies have reported that the co-residency of H-type hypertension could aggravate the side effects of cardiovascular and cerebrovascular diseases4. Notably, 75% of patients in China with H-type hypertension have primary hypertension, which seriously affects the quality of life5. At present, the treatment of H-type hypertension mainly includes Western medicine. However, it may cause certain adverse effects and poor compliance and can no longer meet the needs for the comprehensive management of H-type hypertension.
Traditional Chinese medicine (TCM) is a unique resource with a history of more than 2,000 years in China. Due to the unmet need for hypertension control in Western medicine, clinicians have begun to consider the potential role of TCM in the prevention and treatment of H-type hypertension6. Huotan Jiedu Tongluo Decoction (HTJDTLD) is a traditional Chinese medicine formula formulated by Professor Yue Deng, drawing from his extensive clinical expertise7. Over the course of more than 20 years of clinical application, HTJDTLD has demonstrated remarkable effectiveness in the treatment of cardiovascular and cerebrovascular diseases1. However, whether HTJDTLD has therapeutic effects in H-type hypertension has not been reported. Therefore, we aimed to explore the antihypertensive effects and specific mechanisms of HTJDTLD in rats with H-type hypertension and identify potential therapeutic drugs for the treatment of H-type hypertension.

The Antihypertensive Effects and Mechanisms of Huotan Jiedu Tongluo Decoction in Rats with H-Type Hypertension

H-type hypertension has become a significant public health challenge of human. It mainly relies on Western medicine treatment, which can have sad effects. Our research explores the anti-hypertensive effects and mechanisms of Huotan Jiedu Tongluo decoction, a traditional Chinese medicine formula, in rats with H-type hypertension.Our study indicated that Huotan Jiedu Tongluo decoction had anti-hypertensive effects in rats with H-type hypertension. The underlying mechanism may involve inhibiting ER stress activation-induced apoptosis which provide an effective treatment option for patients. We will explode the potential biomarkers for early diagnosis and prognosis and develop novel therapeutic drugs for H-type hypertension in the future.

Treatment of Methionine-Induced H-Type Hypertensive Rats with Huotan Jiedu Tongluo Decoction (HTJDTLD)

To begin, segregate 50 hypertensive rats into five groups, including control. Give the rats in Group 1, methionine or met group, a diet of 3%methionine for 28 days to induce H-type hypertension. For Group 2 to 4 rats, administer a combination of Huotan Jiedu Tongluo Decoction and enalapril maleate in addition to the methionine diet for 28 days.Next, create a restraining device by placing a cylindrical restraint mesh into a thermal tube and putting the thermal tube into a canvas cover. After 28 days of treatment, place a rat in the mesh. Next place the signal cable of a noninvasive sphygmomanometer under the cover.Position the rat's tail in the gap in the cover and secure it on the stabilizing form pad. Transfer the rat to a quiet measurement site 20 to 30 minutes before blood pressure measurement. Now connect the pressurized sensor's air hose connection, signal connection, and holding tube.Place the pressurization sensor at the tip of the rat's tail. A pulse wave should appear after the rat tail is inserted into the sensor. Press Start/Stop to initiate or stop the measurement.When the blood pressure test is completed, the result menu will pop up automatically. Check the average value of the measurement, standard deviation, standard, and coefficient of variation in the results menu. After euthanizing the rat, dissect it with a pair of surgical scissors and tooth forceps from the perineum to the neck.Turn over the thoracic and abdominal contents. Then navigate to the abdominal aortic bifurcation between the two kidneys. Collect the aorta up to a section of the aortic arch.The systolic and diastolic blood pressures were significantly greater in the Met Group relative to the control group from one to four weeks. The blood pressures decreased after the administration of the Huotan Jiedu Tongluo Decoction. The combined effect of the decoction and/or enalapril maleate had a stronger anti-hypertensive effect than the decoction alone.
