Ecological cultivation is an important way for the sustainable production of traditional Chinese medicine in the context of the carbon peaking and carbon neutrality goals. Facility cultivation and simulative habitat cultivation modes have been developed and applied to develop the endangered Dendrobium huoshanense on the basis of protection. However, the differences in the greenhouse gas emissions and global warming potential of these cultivation modes remain unexplored, which limits the accurate assessment of carbon-friendly ecological cultivation modes of D. huoshanense. Greenhouse gas emission flux monitoring based on the static chamber method provides an effective way to solve this problem. Therefore, this study conducted a field experiment in the facility cultivation and simulative habitat cultivation modes at a D. huoshanense cultivation base in Dabie Mountains, Anhui Province. From April 2023 to March 2024, samples of greenhouse gases were collected every month, and the concentrations of CO_2, CH_4, and N_2O of the samples were then detected by gas chromatography. The greenhouse gas emission fluxes, cumulative emissions, and global warming potential were further calculated, and the following results were obtained.(1)The two cultivation modes of D. huoshanense showed significant differences in greenhouse gas emission fluxes, especially the CO_2 emission flux, with a pattern of facility cultivation>simulative habitat cultivation [(35.60±11.70)mg·m~(-2)·h~(-1) vs(2.10±4.59)mg·m~(-2)·h~(-1)].(2) The annual cumulative CO_2 emission flux in the case of facility cultivation was significantly higher than that of simulative habitat cultivation[(3 077.00±842.00)kg·hm~(-2) vs(221.00±332.00)kg·hm~(-2)], while no significant difference was found in annual cumulative CH_4 and N_2O emission fluxes.(3) The facility cultivation mode had a significantly higher global warming potential than the simulative habitat cultivation mode [(3 053.00±847.00)kg·hm~(-2) vs(196.00±362.00)kg·hm~(-2)]. Overall, the simulative habitat cultivation of D. huoshanense has obvious carbon-friendly characteristics compared with facility cultivation, which is in line with the concept of ecological cultivation of medicinal plants. This study is of great reference significance for the implementation and promotion of the ecological cultivation mode of D. huoshanense under carbon peaking and carbon neutrality goals.

OBJECTIVES: To investigate the interventional effects of 16-week aerobic exercises on the elderly's arteriosclerosis and its mechanism. METHODS: Twenty-seven elderly people with the average age of 62. 70 ±3. 26 joined a 16-week square dance/taijiquan exercise program that conducted 60 minutes each time, six times per week. Arterial stiffness and its related indexes such as systolic pressure(SBP), diastolic pressure(DBP), left brachial-ankle pulse wave velocity (L-baPWV), right brachial-ankle pulse wave velocity(R-baPWV), left ankle brachial index (L-ABI), right ankle brachial index(R-ABI), serum triglyceride(TG), total cholesterol(TC), high density lipoprotein cholesterol(HDL-c), low density lipoprotein cholesterol(LDL-c), superoxide dismutase(SOD), malondialdehyde(MDA) and glutathione peroxidase (GSH-Px) were detected at 3 time points including before exercise program, by the end of exercise for 8 weeks and 16 weeks. RESULTS: ① Compared with pre-exercise, the R-baPWV and R-ABI of the elderly people were decreased at the end of the 8 week, and the L-baPWV, RbaPWV, R-ABI and L-ABI were decreased significantly at the end of the 16 week. ②Compared with pre-exercise, SBP and DBP were declined markedly (<0.01, <0.05) at the end of the 8 week, SBP, DBP and pulse pressure were decreased significantly (<0.01, <0.05) at the end of the 16 week. ③Compared with pre-exercise, TC and LDL-c were declined markedly (<0.01) at the end of the 8 and the 16 week, and there was no difference of the level of TG and LDL-c between pre-exercise and post-exercise. ④There was no evident difference of serum level of SOD, GSH-Px, MDA between pre-exercise and post-exercise at the end of the 8 week. Compared with pre-exercise, the level of serum SOD, GSH-Px was increased evidently while the content of serum MDA was decreased significantly (<0.01). CONCLUSIONS Sixteen-week aerobic exercises could reduce baPWV and ABI levels, regulate blood pressure, blood lipids and lipid peroxides levels of the elderly evidently, thus improve the controlling quality of atherosclerosis.

OBJECTIVETo objectively evaluate the efficacy and safety of Yimusake Tablet in the treatment of premature ejaculation (PE) through a multi-centered large-sample trial.

METHODSWe conducted a multi-centered, open, fixed-dose, and self-compared clinical trial among 300 patients with diagnosed PE. The trial lasted 12 weeks, including 4 weeks without any medication and 8 weeks of treatment with Yimusake Tablet, 2 pills (1 g) per night. We observed the intravaginal ejaculation latency time (IELT) before and after treatment, evaluated the safety of medication, and performed a questionnaire investigation on the patients' satisfaction.

RESULTSOf the 300 PE patients, 288 accomplished the clinical trial. The patients ranged in age from 22 to 60 years, averaging at 31.6 years. The mean IELT of the patient was 62.5 seconds at baseline, 168.9 seconds after 4 weeks of treatment with Yimusake Tablet, and 222.2 seconds after 8 weeks of medication. Among the 157 patients with normal erectile function (IIEF >21), the mean IELT was 71.4 seconds before treatment, 147.4 seconds after 4 weeks of medication, and 172.5 seconds after 8 weeks of medication. The patients' satisfaction was significantly increased after treatment. Those complicated by mild to moderate erectile dysfunction achieved different degrees of improvement in the IIEF-5 score, with a mean increase of 3.8. Only a few patients experienced mild adverse events, including constipation, dry mouth, nose bleeding, abdominal pain, and lumbosacral pain, which were all relieved without drug withdrawal.

CONCLUSIONYimusake Tablet is a safe and effective medicine for the treatment of PE.
