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 observe the clinical efficacy and safety of Jianpi Bushen Jiedu Prescription combined with 5-fluorouracil (5-FU)-based chemotherapy and targeted therapy for the treatment of advanced colorectal cancer patients with liver and kidney yin deficiency combined with spleen deficiency pattern.Methods:A randomized controlled trial was conducted. A total of 72 hospitalized patients with advanced colorectal cancer treated at the Department of Oncology, Nanjing Hospital of Traditional Chinese Medicine Affiliated to Nanjing University of Chinese Medicine from October 2022 to January 2024 were enrolled as study subjects. Using a random number table method, they were allocated into two groups, with 36 patients in each group. The control group received the mFOLFOX6/FOLFIRI combined with bevacizumab regimen, while the treatment group was administered additional oral Jianpi Bushen Jiedu Prescription on the basis of the control group. Two weeks was a cycle in both groups, with a total of 6 cycles of treatment. Serum levels of carcinoembryonic antigen (CEA), carbohydrate antigen 199 (CA199), and carbohydrate antigen 724 (CA724) were detected using electrochemiluminescence; the Karnofsky Performance Status (KPS) scale was utilized to evaluate patients' functional status; vital signs were continuously monitored, and adverse reactions were recorded. The short-term efficacy and TCM syndrome efficacy of patients were evaluated.Results:The treatment group demonstrated higher objective response rate (ORR) [31.25% (10/32) vs. 21.88% (7/32), χ2=0.72] and disease control rate (DCR) [84.38% (27/32) vs. 71.88% (23/32), χ2=1.46] compared to the control group, without statistical significance ( P>0.05). Post-treatment levels of CEA [4.09 (3.31,8.57) μg/L vs. 10.07 (4.55,22.35) μg/L, Z=-2.10] and CA72-4 [4.54 (2.04,10.99) mU/L vs. 9.48 (4.34,18.95) mU/L, Z=-2.52] in the treatment group were significantly lower than those in the control group ( P<0.05). The total effective rate of TCM syndrome was significantly higher in the treatment group [78.13% (25/32)] compared with the control group [50.00% (16/32)], with statistical significance ( χ2=5.50, P=0.019). Post-treatment KPS scores in the treatment group [80.0 (80.0, 80.0) vs. 70.0 (62.5, 80.0), Z=-2.76] were significantly higher compared with the control group ( P<0.01). During the treatment period, the treatment group showed statistical significance compared with the control group in the incidence of hemoglobin decrease ( χ2=4.66), leukopenia decrease ( χ2=4.27), and peripheral neuropathy ( χ2=3.93), with statistical significance ( P<0.05). Conclusion:The addition of Jianpi Bushen Jiedu Prescription to 5-FU-based chemotherapy combined with targeted therapy demonstrates significant clinical benefits in advanced colorectal cancer patients, including reducing tumor marker levels, alleviating clinical symptoms, improving quality of life, and mitigating treatment-related toxicities, with a good safety.

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:The purpose of this study was to examine the clinical features and initial treatment outcomes of elderly individuals with idiopathic membranous nephropathy.Methods:This study retrospectively analyzed the clinical characteristics and therapeutic effect of hospitalized patients aged 60 years or older with renal-biopsy-proven idiopathic membranous nephropathy for at least one year.Results:This study enrolled a total of 91 elderly patients with IMN, consisting of 51 males(56.0%)and 40 females(44.0%). The median age of the patients was 67 years.The urinary protein creatinine ratio(uPCR)and urinary albumin creatinine ratio(uACR)of the patients were 4 454.3 mg/g and 2 258.5 mg/g, respectively.The median 24-hour urinary protein and urinary albumin levels were 5 098.2 mg/24 h and 2 800.6 mg/24 h, respectively.The average estimated glomerular filtration rate(eGFR)was(60.5±20.4)ml·min -1·1.73 m -2.Out of the total of 61 patients, 67.0% achieved remission, including complete and partial remission, within a year of renal biopsy.The levels of uPCR and uACR were significantly higher in the non-remission group compared to the remission group(5 462.5 vs.2 271.1 mg/g, P<0.001; 2 774.4 vs.1 320.0 mg/g, P=0.001). Additionally, the levels of 24h urinary protein and urinary albumin were significantly higher in the non-remission group compared to the remission group(6 526.4 vs.3 210.4 mg/g, P=0.002; 3 067.7 vs.2 102.4 mg/g, P=0.007). The remission group had a higher proportion of patients receiving immunosuppressive therapy(85.2% vs.33.3%, P<0.001). The remission rates were higher in patients treated with glucocorticoid combined with cyclophosphamide, glucocorticoid combined with calcineurin inhibitors, or glucocorticoid combined with mycophenolate mofetil compared to those receiving conservative treatment(88.2% vs.31.0%, P=0.001; 80.0% vs.31.0%, P<0.001; 100.0% vs.31.0%, P=0.007). There was no significant difference in remission rate between the three immunosuppressive therapy groups( P>0.05). However, upon further analysis, it was found that the levels of uPCR, uACR, and serum cystatin C(CysC)were higher in the immunosuppressive therapy groups compared to conservative treatment.Additionally, serum total protein and albumin were lower in the immunosuppressive therapy groups, and these differences were statistically significant( P<0.05). Conclusions:The majority of elderly patients diagnosed with IMN have multiple comorbidities.For those at high risk with elevated urinary protein levels, early initiation of immunosuppressive therapy may lead to a higher initial urinary protein remission rate.Therefore, it is advisable to develop individualized treatment plans for elderly patients with IMN based on their clinical characteristics, as well as the risks and benefits associated with immunosuppressive therapy.

OBJECTIVE
To prepare meloxicam solid dispersions tablets, and to investigate their dissolution in vitro.
METHODS
Crystal inhibition experiments were carried out to screen the carrier materials, and the solid dispersion was characterized by X-ray diffraction(XRD) amd differential scanning calorimeter(DCS). The improved bioavailability of solid dispersions was evaluated through in vivo pharmacokinetic studies. The optimum preparation process of meloxicam solid dispersion tablets was investigated, and the in vitro dissolution curve similarity factor f2 was used as the main evaluation index to screen and optimize the dosage of pH regulator, filler, disintegrator, lubricant, flow aid and the mixing time in the prescription.
RESULTS
The solid dispersion prepared with Kollidon@VA64 as carrier effectively maintained the supersaturated state of the drug in solution. The results of XRD and DSC showed that the crystal state of meloxicam in the solid dispersion was completely transformed into amorphous state. Compared with meloxicam, solid dispersions significantly increased the solubility, and its peak blood concentration(Cmax) and relative bioavailability were increased by 208.09% and 241.78%, respectively. The optimal formulation and process of meloxicam solid dispersion tablets prepared by direct powder pressing method were meloxicam solid dispersion 35.2%, lactose∶microcrystalline cellulose =1∶1.5, sodium citrate 9.8%, crosslinked povidone 8%, magnesium stearate 0.75%, silica 0.8%, and mixing time 5 min. The dissolution similarity factor f2 of the prepared meloxicam solid dispersion tablets and the original reference preparation in different pH medium was above 50.
CONCLUSION
Meloxicam solid dispersible tablets are prepared by hot melt extrusion and powder pressing method. The dissolution and bioavailability of meloxicam are improved, and the dissolution behavior of meloxicam is similar to that of the original reference preparation.
