Circadian rhythm is an endogenous biological clock mechanism that enables organisms to adapt to the earth’s alternation of day and night. It plays a fundamental role in regulating physiological functions and behavioral patterns, such as sleep, feeding, hormone levels and body temperature. By aligning these processes with environmental changes, circadian rhythm plays a pivotal role in maintaining homeostasis and promoting optimal health. However, modern lifestyles, characterized by irregular work schedules and pervasive exposure to artificial light, have disrupted these rhythms for many individuals. Such disruptions have been linked to a variety of health problems, including sleep disorders, metabolic syndromes, cardiovascular diseases, and immune dysfunction, underscoring the critical role of circadian rhythm in human health. Among the numerous systems influenced by circadian rhythm, the skin—a multifunctional organ and the largest by surface area—is particularly noteworthy. As the body’s first line of defense against environmental insults such as UV radiation, pollutants, and pathogens, the skin is highly affected by changes in circadian rhythm. Circadian rhythm regulates multiple skin-related processes, including cyclic changes in cell proliferation, differentiation, and apoptosis, as well as DNA repair mechanisms and antioxidant defenses. For instance, studies have shown that keratinocyte proliferation peaks during the night, coinciding with reduced environmental stress, while DNA repair mechanisms are most active during the day to counteract UV-induced damage. This temporal coordination highlights the critical role of circadian rhythms in preserving skin integrity and function. Beyond maintaining homeostasis, circadian rhythm is also pivotal in the skin’s repair and regeneration processes following injury. Skin regeneration is a complex, multi-stage process involving hemostasis, inflammation, proliferation, and remodeling, all of which are influenced by circadian regulation. Key cellular activities, such as fibroblast migration, keratinocyte activation, and extracellular matrix remodeling, are modulated by the circadian clock, ensuring that repair processes occur with optimal efficiency. Additionally, circadian rhythm regulates the secretion of cytokines and growth factors, which are critical for coordinating cellular communication and orchestrating tissue regeneration. Disruptions to these rhythms can impair the repair process, leading to delayed wound healing, increased scarring, or chronic inflammatory conditions. The aim of this review is to synthesize recent information on the interactions between circadian rhythms and skin physiology, with a particular focus on skin tissue repair and regeneration. Molecular mechanisms of circadian regulation in skin cells, including the role of core clock genes such as Clock, Bmal1, Per and Cry. These genes control the expression of downstream effectors involved in cell cycle regulation, DNA repair, oxidative stress response and inflammatory pathways. By understanding how these mechanisms operate in healthy and diseased states, we can discover new insights into the temporal dynamics of skin regeneration. In addition, by exploring the therapeutic potential of circadian biology in enhancing skin repair and regeneration, strategies such as topical medications that can be applied in a time-limited manner, phototherapy that is synchronized with circadian rhythms, and pharmacological modulation of clock genes are expected to optimize clinical outcomes. Interventions based on the skin’s natural rhythms can provide a personalized and efficient approach to promote skin regeneration and recovery. This review not only introduces the important role of circadian rhythms in skin biology, but also provides a new idea for future innovative therapies and regenerative medicine based on circadian rhythms.

OBJECTIVE: To investigate the regulatory effect of electroacupuncture (EA) at "Neiguan" (PC6) on mitochondrial autophagy in rats with myocardial ischemia-reperfusion injury (MIRI) at different phases (ischemia and reperfusion phases), and to explore the bidirectional regulatory effects of EA at "Neiguan" (PC6) and its potential mechanism. METHODS: Forty-five male SD rats were randomly divided into 6 groups according to the random number table method, namely, sham-operation group (n=9), model-A group (n=6), model-B group (n=9), EA-A1 group (n=6), EA-B1 group (n=6), and EA-B2 group (n=9). Except the rats in the sham-operation group, the MIRI model was established in the other groups with the physical ligation and tube pushing method. In the model-A group, the samples were collected directly after ligation, and in the model-B group, the samples were collected after ligation and reperfusion. In the EA-A1 group, EA was delivered while the ligation was performed, and afterwards, the samples were collected. In the EA-B1 group, while the ligation was performed, EA was operated at the same time, and after reperfusion, the samples were collected. In the EA-B2 group, during ligation and the opening of the left anterior descending branch of the coronary artery, EA was delivered, and after reperfusion, the samples were collected. EA was performed at bilateral "Neiguan" (PC6), with a disperse-dense wave, a frequency of 2 Hz/100 Hz, a current of 1 mA, and a duration of 30 min. HE staining was employed to observe the morphology of cardiomyocytes, TUNEL was adopted to detect the apoptosis of cardiomyocytes, transcriptome sequencing was to detect the differentially expressed genes in the left ventricle, JC-1 flow cytometry was to detect the mitochondrial membrane potential (MMP) of cardiomyocytes, Western blot was to detect the protein expression of phosphatase and tensin homolog-induced kinase 1 (Pink1), Parkin and p62 in the left ventricle of rats, and ELISA was to detect the levels of serum creatine kinase isoenzyme (CK-MB) and cardiac troponin I (cTn-I) in the rats. RESULTS: Compared with the sham-operation group, the cardiomyocytes of rats in the model-B group were severely damaged, with disordered arrangement, unclear boundaries, broken muscle fibers, edema and loose distribution; and the cardiomyocytes in the EA-B2 group were slightly damaged, the cell structure was partially unclear, the cells were arranged more regularly, and the intact cardiomyocytes were visible. Compared with the sham-operation group, the apoptosis of cardiomyocytes increased in the model-B group (P<0.001); and when compared with the model-B group, the apoptosis alleviated in the EA-B2 group (P<0.001). The differentially expressed genes among the EA-B2 group, the sham-operation group and the model-B group were closely related to cell autophagy and mitochondrial autophagy. Compared with the sham-operation group, MMP of cardiomyocytes was reduced (P<0.001), the protein expression of Pink1, Parkin, and p62 of the left ventricle and the levels of serum CK-MB and cTn-I were elevated in the model B group (P<0.001). In comparison with model-A group, the MMP of cardiomyocytes and the levels of serum CK-MB and cTn-I were reduced (P<0.001, P<0.05), and the protein expression of Pink1 in the left ventricle rose in the EA-A1 group (P<0.01). Compared with the model-B group, MMP of cardiomyocytes increased (P<0.001), the protein expression of Pink1, Parkin, and p62 of the left ventricle, and the levels of serum CK-MB and cTn-I decreased (P<0.001) in the EA-B1 group and the EA-B2 group. When compared with the EA-A1 group, MMP of cardiomyocytes increased (P<0.001), and the protein expression of Pink1, Parkin, and p62 of the left ventricle, and the levels of serum CK-MB and cTn-I decreased in the EA-B1 group (P<0.01). CONCLUSION EA at "Neiguan" (PC6) can ameliorate MIRI in rats, which may be achieved through the Pink1/Parkin-mediated mitochondrial autophagy pathway. EA can alleviate myocardial injury by enhancing mitochondrial autophagy at the ischemia phase, and it can reduce reperfusion injury by weakening mitochondrial autophagy at the reperfusion phase.

OBJECTIVE To investigate the effects of Yiqi tongmai formula on atherosclerosis （AS） in ApoE－/－ mice and its mechanism. METHODS Forty ApoE－/－ mice were randomly divided into model group， positive control group [atorvastatin calcium， 2.6 mg/（kg·d）]， and low-dose， medium-dose and high-dose groups of Yiqi tongmai formula [0.46， 0.91， 1.82 g/（kg·d）， by raw material]， with 8 mice in each group. Eight C57BL/6J mice were selected as the normal group. Except for the normal group， the other groups were given a high-lipid diet and relevant drug or normal saline intragastrically， once a day， for 12 consecutive weeks. After the last medication， the serum levels of total cholesterol （TC）， triglyceride （TG）， low-density lipoprotein cholesterol （LDL-C） and high-density lipoprotein cholesterol （HDL-C） as well as the contents of tumor necrosis factor-α （TNF-α）， interleukin-1β （IL-1β） and monocyte chemoattractant protein-1 （MCP-1） were measured in mice. The proportion of aortic plaque area in each group of mice was detected and calculated， and the pathological morphological changes of the aortic sinus were observed； the protein phosphorylation levels of aortic phosphoinositide 3-kinase （PI3K）， protein kinase B （aka Akt） and mammalian target of rapamycin （mTOR） were examined. RESULTS Compared with the model group， the serum levels of TC， TG and LDL-C and the contents of TNF-α， IL-1β and MCP-1 （including low-dose group） were decreased significantly in medium-dose and high-dose groups of Yiqi tongmai formula， while the content of HDL-C in high-dose group was increased significantly （P＜0.05 or P＜0.01）； aortic plaques of the mice were reduced in Yiqi tongmai formula groups to different extents， and pathological changes such as lipid deposition and inflammatory cell infiltration were relieved to different extents； the proportion of aortic plaque area， the protein phosphorylation levels of PI3K， Akt and mTOR in aortic tissue were significantly reduced in medium-dose and high-dose groups of Yiqi tongmai formula （P＜0.05 or P＜0.01）. CONCLUSIONS Yiqi tongmai formula can improve lipid metabolism， reduce inflammatory response， and delay plaque development in AS mice. Its effect may be related to the inhibition of PI3K/Akt/mTOR signaling pathway activation.

Objective: To explore the influence of group psychological counseling on the mental health of children with mother s authoritarian parenting. Methods: From November 2022 to February 2023, 76 students from grades 4 to 6 whose mother showed authoritarian parenting style, while fathers adopted no authoritative, authoritarian or democratic parenting style and who scored ≥65 on the total MHT were selected using the Parenting Style Questionnaire (PBI) and the Mental Health Diagnostic Test (MHT). All the participants and their mothers were randomly assigned to the intervention and control groups. Before and after the intervention, participants filled out questionnaires on parental bonding instrument and mental health test. Control group: regular delivery of mental health education information, 2 times per week, for 8 weeks, without any other intervention. Intervention group: group counseling activities were conducted once a week. Each intervention lasted 1.5-2 hours and lasts for 8 weeks. Before and after the intervention, participants filled in the family parenting style and mental health screening questionnaires. Results: After the intervention, compared with the control group, students in the intervention group showed a significant decrease in the total scale score of the MHT, learning anxiety, social anxiety, allergic tendency, physical symptoms, fear tendency, and impulsive tendency ( t=-0.43, -1.04 , -0.81, P >0.05). After intervention, the intervention group students showed a significant decrease in psychological diagnosis test scores, learning anxiety, anxiety towards others, allergic tendencies, physical symptoms, phobic tendencies, and impulsive tendencies compared to the control group students ( t=-20.00, -5.06, -2.09, -3.36, -6.15, -4.76, -5.15, P <0.05). Conclusion Rregular group psychological counseling can effectively improve the academic anxiety, social anxiety, allergic tendencies, physical symptoms, fearful and impulsive tendencies of students whose mothers with authoritarian parenting style, and greatly improve their mental health.

Objective:To analyze the clinical and genetic characteristics of congenital hypogonadotropic hypogonadism (CHH) in boys.Methods:Cross-sectional study.Clinical data, laboratory data and genetic results of boys who were genetically diagnosed with CHH at the Department of Endocrinology of Shenzhen Children′s Hospital from December 2019 to February 2023 were collected in this retrospective study.Their clinical manifestations, hormone levels and gene mutations were analyzed.The non-normal distribution was represented by the median.The rank sum test was used to compare the non-normal distribution data between the two groups.Results:A total of 27 boys were genetically diagnosed with CHH, with the age at first diagnosis ranging from 0.3 to 16.6 years old.All these children presented with micropenis (100%), of whom 16 were complicated with cryptorchidism (59.3%), 9 with microrchidia (33.3%), 7 with simple micropenis (25.9%), and no had simple cryptorchidism.Three children had cardiovascular dysplasia.The median of basal luteinizing hormone(LH) level was 0.09 IU/L, and 92.5%(25/27) of children had the basal LH level below 1.00 IU/L.The median of peak LH level after gonadotropin-releasing hormone(GnRH) stimulation was 1.42 IU/L, and 96.2%(26/27) of children had the peak LH level below 4.00 IU/L.The median of serum inhibin B was 41.15 μg/L, and the median of serum anti-Müllerian hormone(AMH) was 12.62 mg/L.The serum AMH level of children with cryptorchidism was significantly lower than that of children without cryptorchidism (10.02 mg/L vs.50.50 mg/L, P<0.05). A total of 12 gene mutations were detected in the 27 children, of which 1 was biallelic mutation.The most common gene mutations were in CHD7 and ANOS1 genes (7 children each, both accounting for 51.8%), followed by FGFR1 gene (3 children, 11.1%). After short-term treatment by GnRH pump or subcutaneous injection of recombinant human follicle stimulating hormone in 4 children, the levels of serum inhibin B and AMH increased significantly, and the testicular volume also increased. Conclusions:CHH is a congenital disease with different clinical manifestations at different ages.The main manifestations in childhood are micropenis and cryptorchidism, and some children have microrchidia.Its diagnosis in prepuberty is difficult, but genetic testing is of great significance for early diagnosis.

Objective:To explore the potential categories of post-traumatic stress disorder (PTSD) trajectories in women with multiple in vitro fertilization-embryo transfer (IVF-ET) failures, and to analyze the effects of different demographic characteristics and psychological factors on the potential categories of PTSD trajectories.Methods:This was a prospective empirical research, from May 2021 to October 2022, women with IVF-ET failure ≥ 2 times in the reproductive department of Shanghai First People′s Hospital from May 2021 to October 2022 were selected as the research objects. Post-traumatic stress disorder civilian version scale was used for 4 follow-ups at 3 d (T1), 10 d (T2), 20 d (T3) after the last transplantation failure and 3 d before the next transplantation cycle (T4). Telephone follow-up and online follow-up were combined to obtain the PTSD level at 4 time points. Potential categories of PTSD score trajectories at four time points were identified using a latent category growth model, and analyze influencing factors using unordered multi classification logistic analysis.Results:Totally 196 IVF-ET women were admitted, aged (29.42 ± 4.13) years. Three PTSD trajectories were fitted in this study, including 82 cases (42%) in non-PTSD group, 61 cases (31%) in mild PTSD group and 53 cases (27%) in elevated PTSD group. Logistic regression analysis showed that age, education level, fertility pressure and marital adjustment level were the predictors of PTSD trajectory in women with multiple IVF-ET failures. Compared with the non-PTSD group, women aged ≥35 years, with lower education level and marital adjustment level were more likely to enter the elevated PTSD group ( OR=4.570, 8.540, 0.949, all P<0.05). Women aged 35 years and with greater reproductive pressure were more likely to enter the mild PTSD group ( OR=3.871, 1.063, both P<0.05). Conclusions:There is group heterogeneity in the trajectories of PTSD in women with multiple IVF-ET failures in the next transplantation cycle. Old age, low education level, high fertility pressure and poor marital adjustment can predict the trajectories of PTSD. Fertility stress and marriage adjustment are changeable variables. Medical staff can relieve women′s fertility pressure through health education and mindfulness intervention, promote a good state of marriage adjustment, and minimize the adverse effects of PTSD on the next cycle of conception.
