Several types of arthritis share the common feature that the generation of inflammatory mediators leads to joint cartilage degradation. However, the shared mechanism is largely unknown. H2BK120ub1 was reportedly involved in various inflammatory diseases but its role in the shared mechanism in inflammatory joint conditions remains elusive. The present study demonstrated that levels of cartilage degradation, H2BK120ub1, and its regulator WW domain-containing adapter protein with coiled-coil (WAC) were increased in cartilage in human rheumatoid arthritis (RA) and osteoarthritis (OA) patients as well as in experimental RA and OA mice. By regulating H2BK120ub1 and H3K27me3, WAC regulated the secretion of inflammatory and cartilage-degrading factors. WAC influenced the level of H3K27me3 by regulating nuclear entry of the H3K27 demethylase KDM6B, and acted as a key factor of the crosstalk between H2BK120ub1 and H3K27me3. The cartilage-specific knockout of WAC demonstrated the ability to alleviate cartilage degradation in collagen-induced arthritis (CIA) and collagenase-induced osteoarthritis (CIOA) mice. Through molecular docking and dynamic simulation, doxercalciferol was found to inhibit WAC and the development of cartilage degradation in the CIA and CIOA models. Our study demonstrated that WAC is a key factor of cartilage degradation in arthritis, and targeting WAC by doxercalciferol could be a viable therapeutic strategy for treating cartilage destruction in several types of arthritis.

Non-small cell lung cancer (NSCLC) is a malignant tumor with a high global incidence rate, accounting for about 10.54% of all new cancer cases and posing a serious threat to human health. Due to significant individual variations in the efficacy of immunotherapy among NSCLC patients, it is necessary to identify accurate detection indicators to screen appropriate populations, monitor treatment efficacy, and assist in prognosis assessment. Programmed death-ligand 1 (PD-L1), as an immunosuppressive molecule expressed on the surface of tumor cells and various immune cell membranes, can serve as a "companion diagnostic" or "supplementary diagnostic" tool to guide clinical treatment decisions for metastatic NSCLC patients. Given that tumor tissue PD-L1 testing is an invasive procedure and its reliability is still under debate, the assessment of PD-L1 expression via liquid biopsies, such as circulating tumor cells, will play a significant role in predicting treatment response and prognosis in NSCLC patients.

Various dynasties of herbs and prescription books recorded the specifications, processing, and clinical application of Schisandrae Chinensis Fructus. The clinical application of Schisandrae Chinensis Fructus mainly focuses on astringency, tonifying qi and generating fluids, nourishing the kidneys and calming the heart. There have been few reports on the exploration on textual study on other functions and usage precautions of Schisandrae Chinensis Fructus; at present, the classic prescriptions containing Schisandrae Chinensis Fructus do not clearly indicate their specific specifications and processing in the prescription composition. Textual study has found that different processed products of Schisandrae Chinensis Fructus have different clinical therapeutic effects. For raw use, it is more suitable to use light agents to bring adversely risen qi downward, steam to produce light agents to increase transparency, honey to produce leveling agents is better for moistening the lungs and nourishing yin, wine honey to produce leveling agents can supplement deficiency and promote blood circulation, wine to produce heavy agents can strengthen acid absorption. It is suggested further in-depth research on steamed products, honey products, and honey wine products to broaden clinical application options and improve the accuracy of clinical medication. The clinical application of Schisandrae Chinensis Fructus has different emphases and evolution in different dynasties. In the Tang Dynasty, Schisandrae Chinensis Fructus could reduce the qi of the upper, middle, and lower energizers, and eliminate deficiency heat; during the Five Dynasties period, Schisandrae Chinensis Fructus could nourish qi, improve eyesight, warm the middle, and bring adversely risen qi downward; During the Jin and Yuan dynasties, Schisandrae Chinensis Fructus was used to warm water and treat cholera, as well as to improve muscle function; in the Ming Dynasty, Schisandrae Chinensis Fructus was proposed to reduce qi and strengthen yin, treating the critical condition of yin and yang deficiency; during the Qing Dynasty, Schisandrae Chinensis Fructus could prevent summer heat, and external application to sores could astringent and invigorate the muscles. Schisandrae Sphenantherae Fructus has records of dispersing phlegm and fire, and dispelling wind pathogens. This article reviewed the relevant records of Schisandrae Chinensis Fructus in traditional Chinese herbs and prescriptions throughout history, summarized the efficacy characteristics of Schisandrae Chinensis Fructus under different processing methods, clinical applications under historical evolution, and main contraindications for use, proposed recommendations for the application of Schisandrae Chinensis Fructus in classic and commonly used prescriptions, which can provide scientific basis for the precise selection of different specifications and processed products of Schisandrae Chinensis Fructus and Schisandrae Sphenantherae Fructus, as well as scientific guidance for their rational application in drug development.

Objective:To establish a classification system for the repair band in the subchondral bone origination point in MRI for traumatic osteonecrosis of the femoral head (ONFH) and preliminarily explore the correlation between this classification and the progression of femoral head collapse.Methods:A retrospective analysis was conducted on 73 cases of traumatic ON-FH treated at the Quanzhou Orthopedic-traumatological hospital from January 2000 to December 2019. Among them, there were 46 males and 27 females with an average age of 34.9±8.3 years (range 19-55 years). Clinical and radiological data such as age, gender, side, fracture classification, reduction quality, JIC classification, and bone repair band (BRB) classification were recorded. The progression of traumatic ONFH was assessed using the ARCO staging system, with stages IIIA and IIIB defined as mild collapse and progressive collapse, respectively. The BRB classification was established based on MRI findings, and the inter- and intra-observer consistency of the BRB classification was analyzed using Kappa test. The correlation between the BRB classification and progressive femoral head collapse was analyzed using the Kaplan-Meier survival curve and binary variable Cox regression analysis.Results:According to the BRB classification, 73 cases were divided into type 1 with superficial lesion in 38.4%, type 2 with uncertain lesion in 21.9%, and type 3 with extensive lesion in 39.7%. The inter-observer consistency Kappa value for the BRB classification was 0.798, and the intra-observer consistency Kappa value was 0.896, indicating a high level of consistency. A follow-up of 73 cases (54.8±34.9 months, range 24-165 months) showed a significant correlation between the BRB classification and ARCO staging at the last follow-up (χ 2=37.556, P<0.001), with progression to stages IIIA and IIIB as follows: type 1 had 3 and 1 cases, type 2 had 4 and 1 cases, and type 3 had 14 and 12 cases, respectively. Using the occurrence of progressive collapse (stage IIIB) as the endpoint, the risk of progression to stage IIIB for type 2 was not statistically different from type 1 [ HR=1.766, 95% CI (0.465, 6.702), P=0.403]; the risk of progression to stage IIIB for type 3 was significantly higher than for type 1 [ HR=15.126, 95% CI (4.708, 48.592), P<0.001]. Conclusion:The BRB classification is closely related to the progression of traumatic ONFH and is an independent risk factor for predicting the occurrence of progressive collapse; this classification is helpful for early diagnosis and predicting the progression of collapse and treatment plan decision-making.

Objective:To analyze the correlation between the skin temperature changes in the radiation area and the occurrence of radiodermatitis during postoperative radiotherapy for female breast cancer and to explore the application value of skin temperature monitoring in the early warning of radiodermatitis risks.Methods:A total of 103 patients who received three-dimensional conformal radiotherapy after radical mastectomy in the Fourth Hospital of Hebei Medical University were continuously enrolled from May to November, 2022 in this study. Their skin temperature in the radiation area and radiodermatitis were recorded weekly. The relationships between relative skin temperature differences and different grades of radiodermatitis were determined. The optimal cut-off values for grade ≥ radiodermatitis were calculated, and the predictive effect was evaluated using the receiver operating characteristic (ROC) curve. Furthermore, the radiodermatitis risks under different skin temperatures were compared using binary logistic regression.Results:There was a positive correlation between the skin temperature in the radiation field and the grade of radiodermatitis. The optimal cut-off values for the average relative skin temperature difference of the chest wall (under 40 Gy/20 fractions), the maximum relative skin temperature difference of the chest wall (under 40 Gy/20 fractions), and the relative skin temperature difference of the supraclavicular block (under 30 Gy/15 fractions) were 0.45℃, 0.55℃, 0.15℃, respectively. The patients were divided into low- and high-risk groups based on the optimal cut-off values (0.45℃, 0.55℃, and 0.15℃). Binary logistic regression result showed that the risks of grade ≥ 2 radiodermatitis in the high-risk group were 5.71, 4.29, and 5.15 times those in the low-risk group, respectively ( OR = 5.71, 95% CI 1.81-17.99, P = 0.003; OR = 4.29, 95% CI 1.65-11.12, P = 0.003; OR = 5.15, 95% CI 2.16-12.31, P < 0.001). Conclusions:Skin temperature monitoring using medical infrared thermometers can be used to effectively predict the occurrence of grade ≥ 2 radiodermatitis. The skin temperature changes in the radiotherapy area should be closely observed. The risk of grade ≥ 2 radiodermatitis will increase when the mean and maximum relative temperature differences of the chest wall increase by 0.45℃ and 0.55℃, respectively under 40 Gy/20 fractions of radiotherapy or when the relative temperature differences of the supraclavicular block increases by 0.15℃ under 30 Gy/15 fractions of radiotherapy.

OBJECTIVE To prepare and characterize curcumin nanomicelles (hereinafter referred to as Cur/mPEG-PBLA micelles), and to evaluate the in vitro hepatoprotective activity against alcohol liver disease (ALD). METHODS Cur/mPEG-PBLA micelles were prepared with the dialysis method using methoxy-poly(ethylene glycol)-poly(β-benzyl-L-aspartate) (mPEG-PLGA) as the carrier. The appearance and microscopic morphology of Cur/mPEG-PBLA micelles were observed, and particle size, polydispersity index, Zeta potential, encapsulation efficiency and drug loading content were all detected. The in vitro release, pH stability, thermal stability, dilution stability, storage stability, plasma stability tests, and hemolysis experiments were all performed. The cell model of ALD was established with anhydrous ethanol intervention using human liver cancer cells and normal liver cells as objects, Cur reference solution as reference, to evaluate in vitro preventive and ameliorative effects of Cur/mPEG- PBLA micelles on ALD. RESULTS The prepared Cur/mPEG-PBLA micelles exhibited a pale-yellow milky light, with a spherical shape and uniform distribution. The average particle size was about 140 nm, and the polydispersity index was less than 0.3. Zeta potential was (-8.15±0.05) mV; the encapsulation efficiency was (73.26±3.16)%, and the drug loading content was (4.87± 0.42)%. The cumulative release of Cur reference substance was close to 80% at 10 h; the cumulative release of Cur/mPEG-PBLA micelles at 8 h was 28.94% and only 48.25% at 48 h. pH stability and thermal stability of Cur/mPEG-PBLA micelles were better than those of Cur reference solution; Cur/mPEG-PBLA micelles showed good dilution stability, storage stability and plasma stability, and would not cause hemolysis. Cur reference solution and Cur/mPEG-PBLA micelles had varying degrees of in vitro preventive and ameliorative effects on ALD in two types of cells; after 48 h of application, the above effects of Cur/mPEG-PBLA micelles were significantly better than those of Cur reference solution at the same mass concentration (P<0.05). CONCLUSIONS Cur/mPEG-PBLA micelles can improve pH stability and thermal stability of Cur, delayits degradation rate, and have better in vitro hepatoprotective activity against ALD.

In order to provide basic information for the utilization and development of famous classical formulas containing Bletillae Rhizoma, this article systematically analyzes the historical evolution of the name, origin, harvesting and processing of Bletillae Rhizoma by reviewing the ancient materia medica, prescription books, medical books and modern literature. The research results showed that Baiji(白及) was the main name, some scholars took Baiji(白芨) as its main name, and there were many other names such as Baiji(白给), Baigen(白根), Baiji(白苙). The mainstream source of Bletillae Rhizoma was the tubers of Bletilla striata, and drying, large, white, solid, root-free and skin removed completely were the good quality standards. With the promotion of wild to cultivated medicinal materials, there were certain differences between their traits, and the quality evaluation indexes should be adjusted accordingly. The origin of records in the past dynasties was widely distributed, with Guizhou and Sichuan having high production and good quality in modern times. The harvesting period is mostly in spring and autumn, and harvested in autumn was better. The processing and processing technology is relatively simple, and it was used fresh or powdered in past dynasties, while it is mainly sliced for raw use in modern times. Based on the results, it is suggested that the tubers of Bletilla striata of Orchidaceae should be used in the famous classical formulas, and it should be uniformly written as Baiji(白及). And if the original formula indicates the requirement of processing, it should be operated according to the requirement, if the requirement of processing is not indicated, it can be used in raw form as medicine.
