Depressive symptoms have been found to be highly prevalent among patients with coronary heart disease (CHD) and seriously affect the patients' quality of life. However, most psychotropic drugs have warnings about potential side effects. Accordingly, safer effective alternatives are urgently demanded. Angina pectoris of CHD is considered as "chest stuffiness and heartache syndrome" in traditional Chinese medicine, with the major syndrome type named Qi stagnation and blood stasis. Qi-regulating and blood circulation-promoting therapy has increasingly shown unique advantages in CHD patients. This study investigated the efficacy of Xuefu Zhuyu decoction, a representative prescription of Qi-regulating and blood circulation-promoting therapy, on angina pectoris patients with depressive symptoms. Depressive symptoms were stratified at baseline in 30 patients with stable angina pectoris who participated in both baseline and 12-week follow-up studies. After performing a stratified analysis, the angina pectoris-specific health status and traditional Chinese medicine "chest stuffiness and heartache syndrome" were evaluated by self-reports using the associated questionnaire scales, respectively. We measured serum concentrations of serotonin, brain-derived neurotrophic factor, and ATP, which are associated with the development of depression. We found that the Xuefu Zhuyu granule significantly improved the angina pectoris-specific health status in patients after 12 weeks of treatment; specifically, it had a better curative effect on patients with depressive symptoms. Xuefu Zhuyu granule also significantly improved the chest stuffiness and heartache syndrome in patients with depressive symptoms (efficacy index is 61.24%, P < 0.05 versus baseline). Interestingly, Xuefu Zhuyu granule has been found to be more susceptible to improving ATP levels in patients with depressive symptoms, indicating that the improvement in serum ATP levels might account for the better efficacy of Xuefu Zhuyu granule in patients with depressive symptoms. Our data provide prospective evidence that Xuefu Zhuyu granule improves angina pectoris-specific health status through regulating Qi and promoting blood circulation. This trial is registered with ChiCTR-IOR-15006989. [ABSTRACT FROM AUTHOR]

Objective. A Chinese herbal prescription, Yiqi Jiedu (YQJD) decoction, is used for injuries caused by radiotherapy. This study aimed to investigate the dynamic protective effects of YQJD decoction in mice on radiation damage at different time points of the testis. Methods. The 200 male Balb/c mice were randomly divided into 5 groups (blank, model, Anduolin, low-dose YQJD, and high-dose YQJD groups). Blank and model groups were all given stomach deionized water. Anduolin group and high and low dose of Chinese herb groups were treated with Chinese material medical decoction compound for 2 weeks before being irradiated. Except for the blank group, other groups were given whole-body one-time irradiation of 5.5 Gy 60Co gamma rays. Histopathology examination of testes was conducted on the 1st, 7th, 21st, and 35th day after irradiation, respectively. Indexes of sperm motility rate, sperm count, serum levels of testosterone (T), estradiol (E2), follicle-stimulating hormone (FSH), and luteinizing hormone (LH) were also measured correspondingly. Result. Compared to 1 day and 7 days after irradiation, most of the indexes, including testis index, sperm motility, and count, were decreased on the 21st and 35th day in all irradiated groups. However, compared with the model group, the indexes to assess sperm quality and the morphological structures of testis in low-dose and high-dose YQJD groups were significantly recovered on the 21st and 35th days. Additionally, reproductive hormones, including testosterone and estradiol, were recovered more in low-dose and high-dose YQJD groups on the 21st and 35th days. Conclusion. The YQJD decoction is able to accelerate the recovery of sperm indexes, testosterone, and estradiol levels of sex hormones in mice after irradiation and demonstrated good protective effects on the testis.

Objective. To explore the feasibility of evaluating the effectiveness and safety of electroacupuncture versus sham electroacupuncture for patients with knee osteoarthritis (KOA). Method. A pilot randomized controlled trial was conducted at a teaching hospital in Beijing. A total of 30 patients with KOA (Kellgren grade II or III) were randomly allocated to an eight-week treatment of either electroacupuncture or sham electroacupuncture. Patients and outcome assessors were blinded to group allocation. The primary outcome was the proportion of responders achieving at least 1.14 seconds decrease in the Timed Up and Go Test (TUG) at week eight compared with baseline. The secondary outcomes included the knee range of motion, the knee extensor and flexor muscle strength, Lequesne index, 9-step stair-climb test (9-SCT), and TUG. Results. Of 30 patients allocated to two groups, 27 (90%) completed the study. The proportion of responders was 53.3% (8 of 15) for electroacupuncture group and 26.7% (4 of 15) for sham electroacupuncture group by the intention-to-treat analysis (P = 0.264). There was no statistically significant difference in TUG between the two groups at eight weeks (P = 0.856). The compliance rate measured according to patients who conformed to the protocol and had received treatments ≥20 times was 93.3% (28 of 30). The dropout rate was 20% (3 of 15). Adverse effects were not reported in the study. Conclusion. Our research demonstrated that further evaluation of the effectiveness of electroacupuncture versus sham electroacupuncture was feasible and safe for patients with KOA. Whether or not the electroacupuncture can improve the physical functions of knee joint, expand the knee range of motion, and increase the extensor and flexor muscle strength more significantly than sham electroacupuncture, future studies can be designed with larger sample size, randomization design and less biases. This trial is registered with NCT03366363. [ABSTRACT FROM AUTHOR]
