OBJECTIVE:
To investigate the relationship between angiotensin Ⅱ type 1 receptor autoantibody (AT1-AA) and semen parameters. Methods: The semen samples of 820 male patients who were treated in the Reproductive Medicine Center of Taiyuan Central Hospital from August 2022 to August 2023 were retrospectively analyzed. The levels of AT1-AA and Ang Ⅱ of semen were detected by ELISA, and the function of AT1-AA was detected by cardiomyocyte beating assay in suckling rats. The patients were divided into low group, median group and high group according to the OD values of AT1-AA. The differences in general data and semen parameters between different groups were analyzed. And the correlation between AT1-AA level and semen parameters in semen of all study subjects was analyzed by the method of Spearman analysis. And the relationships between AT1-AA OD value, Ang Ⅱ level and semen parameters in the AT1-AA high value group were analyzed as well.
RESULTS:
AT1-AA was present in semen with good function. There was no significant difference in the general data of patients in different AT1-AA levels (P>0.05). In the comparison of semen parameters among the groups with different levels of AT1-AA, there were differences in sperm concentration, PR concentration, NP%, and ALH among the three groups (P<0.05). And AT1-AA OD value was positively correlated with total sperm count, sperm concentration, PR concentration, and NP%, and negatively correlated with semen volume (P<0.05). In the AT1-AA high value group, the OD value of AT1-AA in semen was negatively correlated with inactive sperm, and positively correlated with total motility ([PR+NP]%), curve rate, mean path rate, and ALH. However, there was no correlation between the level of Ang Ⅱ in semen and semen parameters (P>0.05).
CONCLUSION
The presence of AT1-AA in semen may be associated with the promotion of sperm motility.

OBJECTIVE:
To evaluate the efficacy and safety of Shexiang Tongxin Dropping Pill (STDP) in treating stable angina patients with phlegm-heat and blood-stasis syndrome by exercise duration and metabolic equivalents.
METHODS:
This multicenter, randomized, double-blind, placebo-controlled clinical trial enrolled stable angina patients with phlegm-heat and blood-stasis syndrome from 22 hospitals. They were randomized 1:1 to STDP (35 mg/pill, 6 pills per day) or placebo for 56 days. The primary outcome was the exercise duration and metabolic equivalents (METs) assessed by the standard Bruce exercise treadmill test after 56 days of treatment. The secondary outcomes included the total angina symptom score, Chinese medicine (CM) symptom scores, Seattle Angina Questionnaire (SAQ) scores, changes in ST-T on electrocardiogram and adverse events (AEs).
RESULTS:
This trial enrolled 309 patients, including 155 and 154 in the STDP and placebo groups, respectively. STDP significantly prolonged exercise duration with an increase of 51.0 s, compared to a decrease of 12.0 s with placebo (change rate: -11.1% vs. 3.2%, P<0.01). The increase in METs was significantly greater in the STDP group than in the placebo group (change: -0.4 vs. 0.0, change rate: -5.0% vs. 0.0%, P<0.01). The improvement of total angina symptom scores (25.0% vs. 0.0%), CM symptom scores (38.7% vs. 11.8%), reduction of nitroglycerin consumption (100.0% vs. 11.3%), and all domains of SAQ, were significantly greater with STDP than placebo (all P<0.01). The changes in Q-T intervals at 28 and 56 days from baseline were similar between the two groups (both P>0.05). Twenty-five participants (16.3%) with STDP and 16 (10.5%) with placebo experienced AEs (P=0.131), with no serious AEs observed.
CONCLUSION
STDP could improve exercise tolerance in patients with stable angina and phlegm-heat and blood stasis syndrome, with a favorable safety profile. (Registration No. ChiCTR-IPR-15006020).

Chronic heart failure(CHF) is a series of clinical syndromes in which various heart diseases progress to their end stage. Its morbidity and mortality are increasing year by year, which seriously threatens people's life and health. The diseases causing CHF are complex and varied, such as coronary heart disease, hypertension, diabetes, cardiomyopathy and so on. It is of great significance to establish animal models of CHF according to different etiologies to explore the pathogenesis of CHF and develop drugs to prevent and treat CHF induced by different diseases. Therefore, based on the classification of the etiology of CHF, this paper summarizes the animal models of CHF widely used in recent 10 years, and the application of these animal models in traditional Chinese medicine(TCM) research, in order to provide ideas and strategies for studying the pathogenesis and treatment of CHF, and provide ideas for TCM modernization research.

As an important model animal, fruit fly is characterized by outstanding genetic characteristics, relatively perfect nervous system, rapid reproduction, and low cost. Thus, it has been applied in the research on neuropsychiatric disorders in recent years, showing great potential in life science. The incidence of neuropsychiatric disorders has been on the rise, and the disorders have high disability rate and low case fatality rate. The global drug demand for such diseases is second only to cardiovascular and cerebrovascular diseases. At the moment, the demand of the drugs for the diseases have been rising, and it is an urgent task to develop related drugs. However, the research and development of the drugs are time-intensive and have a high failure rate. A suitable animal model can help shorten the time for drug screening and development, thereby reducing the cost and failure rate. This study reviews the application of fruit flies in several common neuropsychiatric disorders, which is expected to provide new ideas for the research and application of the model animals in traditional Chinese medicine.

Chronic heart failure(CHF) is a comprehensive clinical syndrome caused by multiple factors that result in structural and/or functional abnormalities of the heart, leading to impaired ventricular contraction and/or relaxation functions. This medical condition represents the final stage of various cardiovascular diseases. In the treatment of CHF, multiple clinical studies have demonstrated the benefits of using traditional Chinese medicine(TCM) to control oxidative stress, inflammation, and apoptosis, thereby delaying ventricular remodeling and reducing myocardial fibrosis. In this study, common TCM syndromes in the diagnosis and treatment of CHF in recent years were reviewed and summarized. Five common treatment methods including benefiting Qi and activating blood circulation, enhancing Qi and nourishing Yin, warming Yang for diuresis, eliminating phlegm and dampness, rescuing from collapse by restoring Yang, and corresponding classic prescriptions in prevention and treatment of CHF were concluded under the guidance of TCM syndrome differentiation thinking. Meanwhile, research progress on the modern pharmacological effects of these classic prescriptions was systematically discussed, so as to establish a unique treatment system for CHF by classic prescriptions under the guidance of TCM syndrome differentiation theory and provide innovative diagnosis and treatment strategies for clinical CHF.

Aim To study the effect of salidroside (SAL) on cerebral vascular endothelial cells of rats with ischemic brain injury and its mechanism of action. Methods Twenty-four healthy adult SD male rats were prepared by bolt plugging method to prepare MCAO models,and randomly divided into sham surgery group ( Sham ) , model group ( MCAO ) , and SAL administration group (MCAO + SAL) ,and the concentration of SAL was 50 mg • kg ~ , with a continuous administration for six days. Western blot was used to detect the protein expression of ICAM-1, VCAM-1 , E-se-lectin,and P-selectin in injured brain tissue of rats. In vitro cell experiments using HUVECs were subjected to different concentrations of salidroside (0. 1,1,10 jjunol • L ) and LPS (100 ^g • L ) intervened for 24 hours,and CCK-8 was employed to detect the effects of SAL and LPS on the survival of HUVECs. In vitro an-giogenesis experiments, LPS group ( 100 (jLg • L~ ) and SAL administration group ( LPS + Sal) intervened in HUVECs for 24 hours,and the concentrations of SAL administration were 0. 1,1, and 10 jjunol • L , then the effects of LPS and SAL on their angiogenesis were observed. The protein expressions of ICAM-1, VCAM-1 ,E-selectin,and P-selectin in HUVECs were detected by Western blot. Results SAL could reduce the expression of ICAM-1, VCAM-1, E-selectin, and P-selectin in ischemic brain tissue of MCAO rats. In vitro experimental studies found that salidroside had no effect on the survival of HUVECs. LPS inhibited the angiogenesis of HUVECs, and after the action of SAL, SAL (1,10 jjimol • L ) reversed the effect of LPS and promoted its angiogenesis. Compared with the control group,the expressions of ICAM-1, VCAM-1, E-selectin and P-selectin of HUVECs after LPS stimulation increased, while the expressions of ICAM-1, VCAM-1 , E-selectin and P-selectin were significantly reduced after the addition of SAL, which promoted the angiogenesis ability of HUVECs. Conclusions SAL can improve the ability of cell regeneration in rats with ischemic brain injury and promote the ability of blood vessel formation.
