90,180 and 360 mg·kg-1 on general central nervous system (CNS) of mice was investigated by general behavior observation, nembu-tal subthreshold hypnosis experiment, spontaneous activity test and rotary rod test. The changes in blood pressure, heart rate, electro-cardiogram, breathing flow and frequency in anaesthetic Bealge dogs were observed to evaluate the effects of the capsules respectively at the low, medium and high dosage of 16,32 and 64 mg·kg-1 on cardiovascular and respiratory systems. Results:The general behavior of mice was normal after the administration of Sansheng Jindan capsules. The capsules showed no synergetic hypnotic effect on nembu-tal, and had no influence on the spontaneous activity and body coordination ability of mice (P>0. 05). The blood pressure, ECG and respiratory index of anaesthetic Bealge dogs were also normal after the administration of the capsules (P>0. 05). Conclusion:There are no significant effects of Sansheng Jindan capsules at the experimental dosages on central nervous system of mice and respiratory and cardiovascular systems of Beagle dogs.

Sleep deprivation (SD) has a profound impact on the central nervous system, resulting in an array of mood disorders, including depression and anxiety. Despite this, the dynamic alterations in neuronal activity during sleep deprivation have not been extensively investigated. While some researchers propose that sleep deprivation diminishes neuronal activity, thereby leading to depression. Others argue that short-term sleep deprivation enhances neuronal activity and dendritic spine density, potentially yielding antidepressant effects. In this study, a two-photon microscope was utilized to examine the calcium transients of anterior cingulate cortex (ACC) neurons in awake SD mice in vivo at 24-hour intervals. It was observed that SD reduced the frequency and amplitude of Ca2+ transients while increasing the proportions of inactive neurons. Following the cessation of sleep deprivation, neuronal calcium transients demonstrated a gradual recovery. Moreover, whole-cell patch-clamp recordings revealed a significant decrease in the frequency of spontaneous excitatory post-synaptic current (sEPSC) after SD. The investigation also assessed several oxidative stress parameters, finding that sleep deprivation substantially elevated the level of malondialdehyde (MDA), while simultaneously decreasing the expression of Nuclear Factor erythroid 2-Related Factor 2 (Nrf2) and activities of Superoxide dismutase (SOD) in the ACC. Importantly, the administration of gallic acid (GA) notably mitigated the decline of calcium transients in ACC neurons. GA was also shown to alleviate oxidative stress in the brain and improve cognitive impairment caused by sleep deprivation. These findings indicate that the calcium transients of ACC neurons experience a continuous decline during sleep deprivation, a process that is reversible. GA may serve as a potential candidate agent for the prevention and treatment of cognitive impairment induced by sleep deprivation.

Cancer-related anorexia syndrome (CACS) is one of the main causes for death at present as well as a syndrome seriously harming patients' quality of life, treatment effect and survival time. In current clinical researches, there are fewer reports about empirical traditional Chinese medicine(TCM) prescriptions and patent prescriptions treating CACS, and prescription rules are rarely analyzed in a systematic manner. As the hidden rules are not excavated, it is hard to have an innovative discovery and knowledge of clinical medication. In this paper, the grey screening method combined with the multivariate statistical method was used to build the ″CACS prescriptions database″. Based on the database, totally 359 prescriptions were selected, the frequency of herbs in prescription was determined, and commonly combined drugs were evolved into 4 new prescriptions for different syndromes. Prescriptions of TCM in treatment of CACS gave priority to benefiting qi for strengthening spleen, also laid emphasis on replenishing kidney essence, dispersing stagnated liver-qi and dispersing lung-qi. Moreover, interdependence and mutual promotion of yin and yang should be taken into account to reflect TCM's holism and theory for treatment based on syndrome differentiation. The grey screening method, as a valuable traditional Chinese medicine research-supporting method, can be used to subjectively and objectively analyze prescription rules; and the new prescriptions can provide reference for the clinical use of TCM for treating CACS and the drug development.

OBJECTIVETo evaluate the efficacy of the monotherapy of 15 agents in treating essential hypertension.

METHODSAfter 2-week wash-out, a total of 370 patients with seated diastolic blood pressure 95-114 mmHg and seated systolic blood pressure < 180 mmHg were randomized to different therapeutic groups. 24-hour ambulatory blood pressure monitoring was performed before medication and at the end of 8 weeks.

RESULTAll the agents significantly reduced the 24 hour mean blood pressures after treatment except doxazosin, terazosin, and torasemide.

CONCLUSIONThe result suggested that the angiotensin-converting enzyme inhibitors, angiotensin II receptor blockers, beta-blockers and long-acting calcium antagonists were effective in treating essential hypertension, while the low-dose doxazosin, terazosin and torasemide can be used for combination therapy but not for monotherapy.

Lipids,including fats(triglycerides)and lipoids(phospholipids and sterols),not only serve as an energy source for the body but also play a pivotal role throughout the reproductive process,particularly in the establishment and maintenance of early pregnancy.This encompasses the regulate of early embryonic development and uterine tolerance,and the facilitation of embryo implantation.Given the diversity of lipids,this review focuses on extensively studied lipid mediators such as polyunsaturated fatty acids,endocannabinoids,prostaglandins,lysophosphatidic acid,sphingolipids and steroid hormones.It systematically elaborates on the regulatory effects of fatty acid,phospholipid,and cholesterol metabolism on the formation of endometrial receptivity and embryo implantation,as well as the potential underlying mechanisms.The review aims to provide new insights and feasible intervention approaches for predicting and improving the outcomes of natural pregnancy and/or assisted reproductive technology.

ObjectiveTo investigate the value of micro- dissection testicular sperm extraction (micro-TESE) in the treatment of non-obstructive azoospermia (NOA) in patients with the history of secondary testicular injury.

METHODSTotally, 121 NOA patients with the history of secondary testicular injury underwent micro-TESE in our hospital from September 2014 to December 2017. We analyzed the correlation of the sperm retrieval rate with the causes of testicular injury and compared the outcomes of the ICSI cycles with the sperm retrieved from the NOA males by micro-TESE (the micro-TESE group) and those with the sperm ejaculated from severe oligospermia patients (sperm concentration <1×10⁶/ml, the ejaculate group). Comparisons were also made between the two groups in the female age, two-pronucleus (2PN) fertilization rate, transferrable embryos on day 3 (D3), D3 high- quality embryos, D14 blood HCG positive rate, embryo implantation rate, and clinical pregnancy rate.

RESULTSTesticular sperm were successfully retrieved by micro-TESE in 86.0% of the patients (104/121), of whom 98.4% had the history of orchitis, 75.5% had been treated surgically for cryptorchidism, and 63.6% had received chemo- or radiotherapy. No statistically significant differences were observed between the micro-TESE and ejaculate groups in the 2PN fertilization rate (59.4% vs 69.3%, P > 0.05), D14 blood HCG positive rate (44.6% vs 57.9%, P > 0.05), embryo implantation rate (31.8 %% vs 32.6%, P > 0.05) and clinical pregnancy rate (41.5% vs 48.7%, P > 0.05). However, the rate D3 transferrable embryos was significantly lower in the micro-TESE than in the ejaculate group (40.5% vs 52.2%,P < 0.05), and so was that of D3 high-quality embryos (32.5% vs 42.1%, P < 0.05).

CONCLUSIONSMicro-TESE can be applied as the first choice for NOA patients with the history of secondary testicular injury, but more effective strategies are to be explored for the improvement of ICSI outcomes with the sperm retrieved by micro- TESE.
