Inflammatory diseases (IDs) are a general term of diseases characterized by chronic inflammation as the primary pathogenetic mechanism, which seriously affect the quality of patient′s life and cause significant social and medical burden. Current drugs for IDs include nonsteroidal anti-inflammatory drugs, corticosteroids, immunomodulators, biologics, and antioxidants, but these drugs may cause gastrointestinal side effects, induce or worsen infections, and cause non-response or intolerance. Given the outstanding performance of metal polyphenol network (MPN) in the fields of drug delivery, biomedical imaging, and catalytic therapy, its application in the diagnosis and treatment of IDs has attracted much attention and significant progress has been made. In this paper, we first provide an overview of the types of IDs and their generating mechanisms, then sort out and summarize the different forms of MPN in recent years, and finally discuss in detail the characteristics of MPN and their latest research progress in the diagnosis and treatment of IDs. This research may provide useful references for scientific research and clinical practice in the related fields.

In today's society, depression is a kind of highly prevalent chronic mental illness. It leads to a high disability rate and a heavy economic burden. Depression is defined by fundamental symptoms of low mood and diminished pleasure. Its causes and mechanisms remain unclear, and it presents a broad spectrum of symptoms and a persistent nature that significantly impacts both physical and mental well-being. Treatment in Western medicine primarily focuses on alleviating symptoms, yet it entails numerous adverse effects and contraindications. Traditional Chinese medicine (TCM) treatment is based on resolving depression, which is often accompanied by soothing liver, and the key medicine is Bupleuri Radix. Bupleuri Radix associated prescriptions refer to a class of prescriptions using Bupleuri Radix as the sovereign medicinal or having a high dose of Bupleuri Radix, which are widely used in the field of anti-depression. Previous studies from animal experiments, clinical research, and modern pharmacological research have confirmed that Bupleuri Radix associated prescriptions have precise anti-depression efficacy in multiple ways and at multiple levels, but lack a comprehensive and systematic summarization. This paper summarized and analyzed the literature related to the clinical application and mechanism of action of Bupleuri Radix associated prescriptions in anti-depression treatment. The results showed that the anti-depression mechanism of the Bupleuri Radix associated prescriptions (such as Xiaochaihu Tang, Xiaoyao San, Sini San, Chaihu Shugan San, and Chaihu jia Longgu Muli San) was associated with the effects of regulating monoamine neurotransmitters, the brain-derived neurotrophic factor (BDNF), intestinal flora, and the hypothalamic-pituitary-adrenal (HPA) axis, inhibiting inflammatory responses, and modulating related signaling pathways. Applying them in clinical practice can effectively alleviate patient symptoms, lower the TCM syndrome score and the severity of depression, and also reduce adverse reactions. This underscores advantages of TCM in depression treatment, which offers patients a secure, effective, and more individualized alternative treatment regimen. On this basis, the shortcomings of current studies and the future trend were analyzed. This study aimed to provide an evidence-based medicine basis for the research and development of novel antidepressant medications.

Currently,human health due to corona virus disease 2019(COVID-19)pandemic has been seriously threatened.The coronavirus severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)spike(S)protein plays a crucial role in virus transmission and several S-based therapeutic approaches have been approved for the treatment of COVID-19.However,the efficacy is compromised by the SARS-CoV-2 evolvement and mutation.Here we report the SARS-CoV-2 S protein receptor-binding domain(RBD)inhibitor licorice-saponin A3(A3)could widely inhibit RBD of SARS-CoV-2 variants,including Beta,Delta,and Omicron BA.1,XBB and BQ1.1.Furthermore,A3 could potently inhibit SARS-CoV-2 Omicron virus in Vero E6 cells,with EC50 of 1.016 pM.The mechanism was related to binding with Y453 of RBD deter-mined by hydrogen-deuterium exchange mass spectrometry(HDX-MS)analysis combined with quan-tum mechanics/molecular mechanics(QM/MM)simulations.Interestingly,phosphoproteomics analysis and multi fluorescent immunohistochemistry(mIHC)respectively indicated that A3 also inhibits host inflammation by directly modulating the JNK and p38 mitogen-activated protein kinase(MAPK)path-ways and rebalancing the corresponding immune dysregulation.This work supports A3 as a promising broad-spectrum small molecule drug candidate for COVID-19.

Objective:To evaluate the diagnostic efficacy and practicality of the Jaundice color card (JCard) as a screening tool for neonatal jaundice.Methods:Following the standards for reporting of diagnostic accuracy studies (STARD) statement, a multicenter prospective study was conducted in 9 hospitals in China from October 2019 to September 2021. A total of 845 newborns who were admitted to the hospital or outpatient department for liver function testing due to their own diseases. The inclusion criteria were a gestational age of ≥35 weeks, a birth weight of ≥2 000 g, and an age of ≤28 days. The neonate′s parents used the JCard to measure jaundice at the neonate′s cheek. Within 2 hours of the JCard measurement, transcutaneous bilirubin (TcB) was measured with a JH20-1B device and total serum bilirubin (TSB) was detected. The Pearson′s correlation analysis, Bland-Altman plots and the receiver operating characteristic (ROC) curve were used for statistic analysis.Results:Out of the 854 newborns, 445 were male and 409 were female; 46 were born at 35-36 weeks of gestational age and 808 were born at ≥37 weeks of gestational age. Additionally, 432 cases were aged 0-3 days, 236 cases were aged 4-7 days, and 186 cases were aged 8-28 days. The TSB level was (227.4±89.6) μmol/L, with a range of 23.7-717.0 μmol/L. The JCard level was (221.4±77.0) μmol/L and the TcB level was (252.5±76.0) μmol/L. Both the JCard and TcB values showed good correlation ( r=0.77 and 0.80, respectively) and agreements (96.0% (820/854) and 95.2% (813/854) of samples fell within the 95% limits of agreement, respectively) with TSB. The JCard value of 12 had a sensitivity of 0.93 and specificity of 0.75 for identifying a TSB ≥205.2?μmol/L, and a sensitivity of 1.00 and specificity of 0.35 for identifying a TSB ≥342.0?μmol/L. The TcB value of 205.2?μmol/L had a sensitivity of 0.97 and specificity of 0.60 for identifying TSB levels of 205.2 μmol/L, and a sensitivity of 1.00 and specificity of 0.26 for identifying TSB levels of 342.0 μmol/L. The areas under the ROC curve (AUC) of JCard for identifying TSB levels of 153.9, 205.2, 256.5, and 342.0 μmol/L were 0.96, 0.92, 0.83, and 0.83, respectively. The AUC of TcB were 0.94, 0.91, 0.86, and 0.87, respectively. There were both no significant differences between the AUC of JCard and TcB in identifying TSB levels of 153.9 and 205.2 μmol/L (both P>0.05). However, the AUC of JCard were both lower than those of TcB in identifying TSB levels of 256.5 and 342.0 μmol/L (both P<0.05). Conclusions:JCard can be used to classify different levels of bilirubin, but its diagnostic efficacy decreases with increasing bilirubin levels. When TSB level are ≤205.2 μmol/L, its diagnostic efficacy is equivalent to that of the JH20-1B. To prevent the misdiagnosis of severe jaundice, it is recommended that parents use a low JCard score, such as 12, to identify severe hyperbilirubinemia (TSB ≥342.0 μmol/L).

Objective:To evaluate the effectiveness of surgical methods for correcting pollybeak deformity in Chinese rhinoplasty.Methods:A retrospective chart review was conducted for patients who underwent pollybeak correction between January 2021 and December 2022 at the Department of Plastic and Aesthetic (Burn) Surgery, the Second Xiangya Hospital of Central South University. Individualized correction was tailored based on the etiology and severity of the nasal deformity of each patient, involving techniques such as resection of the anterior part of the nasal septum, reconstruction of nasal tip support, reconstruction of the middle part of the nasal vault, and excision of skin in the upper region of the nasal tip. A modified classification system for pollybeak deformity, the supratip fullness rating scale (SFRS), was developed to evaluate supratip fullness (0-3 points, with higher scores indicating more apparent deformity). The patients aesthetic outcomes were assessed by surgeons using the visual analogue scale (VAS) (0-10 points, with higher scores indicating more apparent deformity), and patient self-assessed using the rhinoplasty outcome evaluation (ROE) questionnaire (0-100 points, with higher scores indicating higher satisfaction). The measurement data of normal distribution was expressed as Mean±SD and analyzed by paired t-test; the measurement data of non-normal distribution was expressed as M( Q1, Q3) and analyzed by Wilcoxon signed rank test. Results:In a cohort study of 53 rhinoplasty patients (7 male, 46 female; age range 19-45 years, mean 29 years), comprising 15 primary and 38 secondary surgeries, nasal tip deformities were evaluated. Deformities were classified as mild (5 cases), moderate (25 cases), and severe (23 cases). Over a follow-up period of 6-17 months (mean 9.5 months), significant aesthetic improvements in the nasal tip region were observed. The SFRS scores decreased from 2(2, 3) preoperatively to 0(0, 0) postoperatively ( Z = -6.58, P < 0.001), and VAS scores decreased from 7.47±1.73 to 1.79±1.67 ( t = -25.61, P < 0.001). High patient satisfaction was indicated by a mean ROE score of 82.45±11.55. No significant complications, such as nasal tip ptosis, skin necrosis, or scar hyperplasia, were reported. Conclusion:Selecting an appropriate surgical method based on the severity and cause of pollybeak deformity can achieve satisfactory outcomes. Post-operative patients exhibit significant aesthetic improvement in the upper nasal tip area, resulting in high patient satisfaction.

Objective:To explore the clinical efficacy of modified superomedial pedicle technique using an inverted T-shaped incision for reduction mammaplasty and mastopexy.Methods:A retrospective analysis was conducted on clinical data of patients who underwent modified superomedial pedicle technique for breast reduction surgery with inverted T-shaped incision between March 2021 and March 2023 at the Department of Plastic and Aesthetic (Burn) Surgery, Second Xiangya Hospital of Central South University. Preoperatively, a handheld Doppler ultrasound blood flow detector was used to detect and mark the exit points of the 2nd to 4th perforating vessels of the internal thoracic artery, and a superomedial pedicle containing at least two perforators was designed based on the perforator locations, with a pedicle width generally about 6 cm. Intraoperatively, the pedicle was rotated superolaterally, moving the nipple-areola complex (NAC) upwards to construct a fuller upper pole of the breast and removing excess skin in the lower fold to form a inverted T-shaped incision. Postoperatively, the blood supply of the NAC, breast morphology, and incidence of complications were observed and followed up. Canfield Mirror 7.1.1 software was utilized to measure pre- and post-operative breast morphology data from lateral photographs at 6 months, including total breast area, maximum breast protrusion, upper pole protrusion, lower pole height, and nipple elevation height. The BREAST-Q questionnaire was used to survey patient satisfaction with breast appearance, psychosocial well-being, sexual well-being, and physical health before surgery and 6-12 months after surgery, with each dimension scoring 0-100 points, where higher scores indicate greater satisfaction and health. SPSS 28.0 software was used for data analysis, with normally distributed measurement data expressed as Mean±SD, and paired t-test was applied for comparisons of pre- and post-operative breast morphology data (the first 4 indicators) and BREAST-Q scores, with P<0.05 considered statistically significant. Results:A total of 56 female patients were included, with an age of (32.0±6.7) years and a body mass index of (29.1±5.7) kg/m 2. Preoperative Doppler ultrasound blood flow detection showed that none of the patients had missing or significantly variant perforators of the superomedial pedicle. The volume of breast tissue removed ranged from 890 to 1 800 ml, averaging 1 250 ml, with an average pedicle width of 5.4 cm (4.0-7.0 cm). The follow-up period was (13.3±2.5) months, during which all patients exhibited good blood supply to the NAC and favorable breast morphology, with universal high satisfaction with surgical outcomes. Postoperatively, one case developed incisional seroma, which resolved naturally within 3 months; two cases experienced minor incision dehiscence, which healed well after dressing changes; all other patients recovered well without any complications such as flap necrosis or hematoma. Comparison of breast morphology data showed significant reductions in postoperative left and right total breast area ( P<0.05 for both), and increases in maximum breast protrusion and lower pole height postoperatively ( P<0.05 for both), while the difference in upper pole protrusion was not statistically significant ( P>0.05 for both); postoperative left and right nipple elevation heights were (6.30±1.84) cm and (6.52±1.66) cm, respectively. Among the 44 patients who completed the BREAST-Q survey both before and after surgery, scores showed significant improvements in postoperative breast satisfaction [(50.30±10.30) points vs. (83.20±6.02) points] ( t=5.17, P=0.008) and psychosocial well-being [(56.20±17.20) points vs. (89.70±2.70) points] ( t=5.09, P=0.010), while sexual well-being and physical health scores did not differ significantly from preoperative scores ( P>0.05 for both). Conclusion:Preoperative identification of perforator locations using a handheld Doppler blood vessel detector, followed by the design of a modified superomedial pedicle technique for reduction mammaplasty with inverted T-shaped incision, can not only ensure NAC blood supply, avoiding ischemic necrosis due to vascular anomalies, but also maximally reduce pedicle width and increase pedicle rotation flexibility, achieving desirable breast shaping effects.
