Polycystic ovary syndrome （PCOS） is a common gynecological endocrine and reproductive disorder，with the main clinical manifestations including ovulation failure，insulin resistance，hyperandrogenism，and obesity. Its occurrence and development are closely related to cellular regulatory mechanisms such as apoptosis，autophagy，oxidative stress，and inflammatory response. Autophagy，as a clearance mechanism that maintains cellular homeostasis，plays a crucial role in maintaining the growth，development，and maturation of oocytes. Exploring the mechanism of autophagy during the occurrence and development of diseases can help develop treatment methods for PCOS by regulating autophagy. Studies have shown that autophagy plays an important role in the pathogenesis of PCOS，and it can affect the occurrence and development of PCOS through multiple pathways，levels，and targets. Traditional Chinese medicine （TCM） regulates autophagy in ovarian granulosa cells or endometrium of patients with PCOS by targeting the expression of autophagy signaling pathways，regulatory factors，and non-coding single-stranded RNA molecules，thereby alleviating inflammation，regulating metabolism disorders，and balancing hormone levels in PCOS. Accordingly，TCM can ameliorate pathological conditions such as insulin resistance，hyperandrogenism，and ovulation failure in PCOS. This article summarizes the TCM formulas and extracts for the treatment of PCOS，as well as the main autophagy pathways and regulatory factors involved，aiming to provide reference and suggestions for the future treatment of PCOS with TCM by regulating autophagy.

ObjectiveTo investigate the intervention effects of Suanzaoren Tang on depression model rats induced by isolation combined with chronic unpredictable mild stress （CUMS）， and to examine its influence on the c-Jun N-terminal kinase （JNK）/proto-oncogene protein （c-Myc）/tumor suppressor protein 53 （p53） signaling pathway， thereby revealing its potential functional mechanism. MethodsA total of 72 male SD rats were randomly divided into six groups using a strict random number table： blank group， model group， fluoxetine group （3.6 mg·kg^-1）， and high-， medium-， and low-dose Suanzaoren Tang groups （10， 5， 2.5 g·kg^-1），with 12 rats in each group. A depression model was established using isolation combined with CUMS. Fluoxetine and different doses of Suanzaoren Tang were administered continuously for 28 days. Behavioral indicators such as sucrose water consumption and open field test scores were recorded. Western blot and immunohistochemistry （IHC） were employed to analyze the expression of key proteins in the JNK/c-Myc/p53 signaling pathway， and the terminal deoxynucleotidyl transferase dUTP nick end labeling （TUNEL） assay was used to evaluate the number of apoptotic cells in the hippocampus. ResultsCompared with the blank group， the model group exhibited a significantly reduced sucrose preference index （P<0.01）， a lower total score of horizontal and vertical movements in the open field test （P<0.01）， significantly increased expression of JNK， c-Myc， and p53 proteins in the hippocampus （P<0.01）， and a higher number of TUNEL-positive cells in the hippocampus （P<0.01）. Compared with the model group， the sucrose preference index and the total score of horizontal and vertical movements in the open field test significantly increased in the high- and medium-dose Suanzaoren Tang groups and the fluoxetine group （P<0.05， P<0.01）. The expression of JNK， c-Myc， and p53 proteins significantly decreased in all Suanzaoren Tang groups （high， medium， and low doses） and the fluoxetine group （P<0.05， P<0.01）. The number of TUNEL-positive cells in the hippocampus also significantly decreased in these groups （P<0.01）. ConclusionSuanzaoren Tang can regulate the expression of JNK/c-Myc/p53 proteins in the hippocampus of depression model rats， and its antidepressant mechanism may be related to its protective effect on hippocampal neurons.

Objective:To explore the application effect of objectives and key results (OKR) management method in the clinical intensive training of emergency department nurses.Methods:A total of 90 nurses from the emergency department of The First Affiliated Hospital of Hebei North University who participated in clinical intensive training from September to December 2022 were selected. They were randomly divided into a control group and an observation group (45 in each group) using a random number table. The observation group was managed using OKR method, while the control group was managed using the conventional management method. The academic performance (theoretical knowledge and practical operation), clinical comprehensive ability (nurse core competency evaluation form), self-learning ability (Self-Rating Scale of Self-Directed Learning), and training satisfaction were compared between two groups of nurses at the end of each month (for a total of 3 months).Results:The observation group had significantly higher theoretical knowledge scores [(65.78±5.11), (77.89±4.22), (85.10±4.70)] and practical operation scores [(62.33±4.01), (72.45±4.29), (83.20±5.10)] than the control group [(61.99±6.09), (74.18±4.09), (82.60±5.40); (60.09±4.56), (70.24±4.11), (80.70±4.60)]. The clinical comprehensive ability (nursing ability and critical clinical thinking), self-learning ability (learning behavior, learning awareness, learning strategies, and learning evaluation), and training satisfaction (theoretical knowledge training, clinical skills training, and work plan) of nurses in the observation group were also higher than those of nurses in the control group.Conclusions:The application of OKR management method in clinical intensive training of emergency department nurses can significantly improve their clinical abilities and knowledge level, mobilize their self-learning ability, and achieve higher satisfaction.

ObjectiveTo study the changes of mitochondrial function of ovarian granulosa cells in women of different ages and the effect of Erzhi-Tiangui prescription on in vitro fertilization-embryo transfer （IVF-ET） outcomes for elderly women， so as to verify the connotation of the "Seven-Seven" theory in the Huangdi's Internal Classic （《黄帝内经》）. MethodA total of 150 infertility patients undergoing IVF-ET at the Reproductive and Genetic Center of Integrative Medicine， Affiliated Hospital of Shandong University of Traditional Chinese Medicine were recruited and assigned into "hree-Seven/Four-Seven （30 cases）， Five-Seven （60 cases）， and Six-Seven （60 cases） groups according to the "Seven-Seven" theory. The Five-Seven and Six-Seven groups were further assigned into control and Chinese medicine subgroups using the random number plus envelope method， and the Chinese medicine group was administrated with Erzhi Tiangui prescription from the start day of controlled ovulation stimulation cycle to the trigger day. The IVF outcome was observed， and Western blot was employed to determine the levels of mitofusin 1 （MFN1）， mitofusin 2 （MFN2）， and dynamin-related protein 1 （Drp1） in the ovarian granulosa cells. ResultCompared with the Three-Seven/Four-Seven group， the control subgroups of the Five-Seven and Six-Seven groups showed decreased retrieved oocytes， two pronuclear （2PN） embryos， available embryos， high-quality embryos， clinical pregnancy rate， and live birth rate （P<0.05）. Moreover， the control subgroup of the Six-Seven group showed decreased fresh embryo transfer rate（P<0.05）. Compared with the control subgroup of the Five-Seven group， that of the Six-Seven group showed reduced retrieved oocytes， 2PN embryos， available embryos， high-quality embryos， and clinical pregnancy rate （P<0.05）. The Chinese medicine subgroup had more retrieved oocytes， 2PN oocytes， and available embryos than the control subgroup in the Five-Seven groups （P<0.05）. The Chinese medicine subgroup had more retrieved oocytes， than the control subgroup in the Six-Seven groups （P<0.05）. The control subgroup of the Six-Seven group showed lower expression levels of Mfn1 and Mfn2 and higher level of Drp1 than the control subgroup of the Five-Seven group （P<0.05）， which indicated that the levels of Mfn1 and Mfn2 in ovarian granulosa cells were down-regulated while the expression of Drp1 was up-regulated with aging （P<0.05）. The Chinese medicine subgroup had higher Mfn2 level and lower Drp1 level than the control subgroup in the Five-Seven group （P<0.05）， and the Chinese medicine subgroup had higher Mfn1 and Mfn2 levels and lower Drp1 level than then control subgroup in the Six-Seven group （P<0.05）. ConclusionsThe prognosis of IVF in women after "Five-Seven" became worse with aging， and the mitochondria in ovarian granulosa cells showed decreased fusion ability and increased fission， which verified the connotation of the "Seven-Seven" theory from the mitochondrial function. Erzhi Tiangui prescription can regulate the mitochondrial function of ovarian granulosa cells in elderly women， up-regulate the expression levels of Mfn1 and Mfn2 to promote mitochondrial fusion， and down-regulate the expression of Drp1 to reduce mitochondrial fission， thus alleviating the ovarian hypofunction caused by aging， improve the development potential of oocytes， and improve the IVF outcomes of elderly women. However， this prescription has limited efficacy for the elderly women in the age range of "Six-Seven".

Age-related ovarian hypofunction includes a decrease in follicle quantity and quality as well as alterations in the ovarian microenvironment，the mechanisms of which are mainly related to mitochondrial dysfunction，free radical and antioxidant systems，telomere and telomerase alterations，and apoptosis，and is one of the major factors contributing to infertility in advanced maternal age （AMA）. Despite the tremendous progress in assisted reproductive technology in recent decades，few breakthroughs have been made in alleviating age-related ovarian hypofunction and improving reproductive outcomes for AMA. In recent years，there has been an increasing number of studies on the multi-level and multi-targeted mechanisms of traditional Chinese medicine （TCM） to improve age-related ovarian hypofunction by modulating mitochondrial homeostasis，alleviating oxidative stress，and inhibiting apoptosis，while more high-quality randomized controlled trials have demonstrated the clinical efficacy of TCM in assisted reproductive technology. Given this，this article presented a systematic review of recent research and randomized controlled trials on the mechanism of Chinese medicine active ingredients，single Chinese medicine， and Chinese medicine compounds in delaying age-related ovarian hypofunction，to clarify the current status and shortcomings of the research. This paper provides medication management of TCM for effectively alleviating age-related ovarian hypofunction and improving reproductive outcomes for AMA.

Objective:To observe any effect of virtual reality (VR) training on the cognitive functioning and functional fitness of nursing home residents with subjective cognitive decline (SCD).Methods:Fifty-six of such residents were randomly divided into an observation group and a control group, each of 28. Both groups received health education and routine care, but the observation group was additionally provided with 45 minutes of VR training three times a week for 6 months. The training included Baduanjin, magic, flying bird, supermarket shopping, gravity ball and gym episodes. Both groups′ cognition was evaluated using the subjective cognitive decline questionnaire (SCD-Q), the Montreal cognitive assessment (MoCA), the Rivermead Behavioural Memory Test (second edition) (RBMT-Ⅱ), a digit symbol substitution test (DSST), an animal fluency test (AFT) and trail-making test A-B (TMT A-B). Functional fitness was quantified using the 8-foot up-and-go test (8UGT), a 30-second arm curl test (30sACT), a 30-second chair stand test (30sCST), a back scratching test (BST), the sit-and-reach test (CSRT) and a 2-minute step test (2MST) before and after the 6-month intervention.Results:After the intervention, the average SCD-Q, MoCA, RBMT-Ⅱ, DSST, TMT-A, and TMT-B scores of the observation group were significantly better than before the intervention, and significantly better than the control group′s averages. And except for the back scratching their functional results were also significantly better, on average, than those of the control group.Conclusions:VR training can effectively improve the cognition and functional fitness of nur-sing home residents with SCD. Such training is worthy of promotion and wider application in nursing homes.

Rare diseases have been a major challenge for clinical medicine and public health challenge in China. One of the effective measures is to conduct proactive research on rare diseases to deal with the disease burden of the diseases. However, low prevalence, disperse distribution of patients, lack of knowledge about the disease course, and phenotype heterogeneity hamper the development of research for rare diseases. Recently, it has been found that patients registry is effective in understanding the course of the disease and accu- mulating the cases and data of clinical research or clinical trial design. At present, most of developed countries or regions in the world have promoted clinical research and clinical trials of new medications on rare diseases by using the registration of rare disease. In 2016, Peking Union Medical College Hospital established China's first registry system at the national level-National Rare Disease Registry System of China(NRDRS). NRDRS has accumulated 68 137 cases data registered by the researchers from China's 101 collaborating hospitals in 29 provinces/municipalities/autonomous regions, covering 171 different, and forming 188 cohorts. To date, NRDRS complete the initial stage of resources buildup.Nex stage will be focused on clinical research and clinical trials related to rare diseases based on NRDRS. This article is on the process of building NRDRS, the potential support for conducting clinical research and clinical trials related to rare diseases, and the challenges will be faced.

To address the increasing need for detecting and validating protein biomarkers in clinical specimens, mass spectrometry (MS)-based targeted proteomic techniques, including the selected reaction monitoring (SRM), parallel reaction monitoring (PRM), and massively parallel data-independent acquisition (DIA), have been developed. For optimal performance, they require the fragment ion spectra of targeted peptides as prior knowledge. In this report, we describe a MS pipe-line and spectral resource to support targeted proteomics studies for human tissue samples. To build the spectral resource, we integrated common open-source MS computational tools to assemble a freely accessible computational workflow based on Docker. We then applied the workflow to gen-erate DPHL, a comprehensive DIA pan-human library, from 1096 data-dependent acquisition (DDA) MS raw files for 16 types of cancer samples. This extensive spectral resource was then applied to a proteomic study of 17 prostate cancer (PCa) patients. Thereafter, PRM validation was applied to a larger study of 57 PCa patients and the differential expression of three proteins in prostate tumor was validated. As a second application, the DPHL spectral resource was applied to a study consisting of plasma samples from 19 diffuse large B cell lymphoma (DLBCL) patients and 18 healthy control subjects. Differentially expressed proteins between DLBCL patients and healthy control subjects were detected by DIA-MS and confirmed by PRM. These data demonstrate that the DPHL supports DIA and PRM MS pipelines for robust protein biomarker discovery. DPHL is freely accessible at https://www.iprox.org/page/project.html?id=IPX0001400000.
