BACKGROUND:Scaffold materials serve as platforms that provide space and structure,playing a crucial role in the regeneration of cartilage tissue.Scholars from around the world are exploring different approaches to fabricate more ideal scaffold materials. OBJECTIVE:To review the design principles and preparation methods of cartilage scaffolds,and to further explore the advantages and limitations of various preparation methods. METHODS:Literature searches were conducted on the databases of CNKI,WanFang Data,PubMed,and FMRS from 1998 to 2023.The search terms were"cartilage repair,cartilage tissue engineering,cartilage scaffold materials,preparation"in Chinese and English.A total of 57 articles were ultimately reviewed. RESULTS AND CONCLUSION:(1)The articular cartilage has a unique structure and limited self-repair capacity after injury.Even if self-repair occurs,the newly formed cartilage is typically fibrocartilage,which is far inferior to normal articular cartilage in terms of structure and mechanical properties.It is difficult to maintain normal function and often leads to degenerative changes.Currently,the design and fabrication of scaffold materials for cartilage repair need to consider the following aspects:biocompatibility and biodegradability,suitable pore structure and porosity,appropriate mechanical properties,and bioactivity.(2)Research on the preparation of cartilage scaffolds has made significant progress,continuously introducing new preparation methods and optimization strategies.These methods have their advantages and disadvantages,providing more possibilities for customized preparation and functional design of cartilage scaffolds according to specific requirements.

Objective:To investigate the efficacy of Compound Musk combined with nimodipine combined with minimally invasive surgery in the treatment of hypertensive cerebral hemorrhage and the effects on serum inflammation, stress and apoptosis.Methods:Prospective research methods was used. A total of 118 patients with hypertensive intracerebral hemorrhage who received treatment in the First Affiliated Hospital of Heilongjiang University of Traditional Chinese Medicine from March 2017 to January 2021 were randomly divided into control group and Compound Musk group (59 cases in each group). After minimally invasive surgery, patients in the control group were treated with nimodipine on the basis of conventional treatment, while patients in the Compound Musk group were treated with compound musk on the basis of the control group. After 2 weeks, the efficacy was evaluated and the levels of serum inflammatory indexes, oxidative stress indexes and apoptosis indexes were measured.Results:The total effective rate in Compound Musk group was higher than that in control group: 98.3% (58/59) vs. 88.1% (52/59), and the difference was statistically significant ( P<0.05). After 2 weeks of treatment, serum inflammatory indexes including nuclear factor-κB (NF-κB), interleukin-1β (IL-1β), matrix metalloproteinase-3 (MMP-3), matrix metalloproteinase-9 (MMP-9); apoptosis indexes including soluble Fas receptor (sFas), soluble Fas ligand (sFAS-L); oxidative stress indexes including advanced oxidation protein products (AOPP), malondialdehyde (MDA) decreased, and some oxidative stress indexes including glutathione peroxidase (GSH-Px), catalase (CAT) increased. The levels of the above inflammatory indexes, apoptosis indexes and oxidative stress indexes in Compound Musk group were lower than those in control group, NF-κB: (18.96 ± 2.17) ng/L vs. (24.10 ± 3.23) ng/L, IL-1β: (12.88 ± 1.74) ng/L vs. (15.19 ± 1.63) ng/L, MMP-3: (5.62 ± 0.95) ng/L vs. (7.97 ± 0.86) ng/L, MMP-9: (7.07 ± 0.86) ng/L vs. (9.26 ± 1.13) ng/L, sFas: (3.24 ± 0.38) μg/L vs. (4.19 ± 0.53) μg/L, sFas-L: (209.17 ± 24.39) ng/L vs. (288.54 ± 37.61) ng/L, AOPP: (10.76 ± 1.84) μg/L vs. (13.51 ± 2.09) μg/L, MDA: (2.87 ± 0.32) μmol/L vs. (3.45 ± 0.34) μmol/L, and the differences were statistically significant ( P<0.05). Some of the above oxidative stress indexes were higher than those in control group, GSH-Px: (3 274.91 ± 376.09) U/L vs. (2 854.19 ± 325.22) U/L, CAT: (60.82 ± 7.43) U/L vs. (52.17 ± 6.48) U/L, the differences were statistically significant ( P<0.05). During treatment, there was no significant difference in the incidence of rash, diarrhea, drug-induced liver and myocardial injury between two groups ( P>0.05). Conclusions:Compound Musk has a positive effect on improving the curative effect and internal environment of patients with hypertensive intracerebral hemorrhage after minimally invasive surgery, and will not increase the occurrence of serious adverse reactions.

Femoral neck fracture (FNF) in the elderly patients is currently a major health challenge worldwide, with excessive consumption of medical resources, high incidence of complications as well as suboptimal outcome and prognosis. Hip joint arthroplasty (HJA) has been the mainstream treatment for FNF in the elderly, but the conventional surgical approaches and techniques are still confronted with a series of bottlenecks such as dislocation, limp and limb length discrepancy. In recent years, direct anterior approach (DAA) for HJA (DAA-HJA) has been a major new choice in the field of joint replacement, which achieves improved clinical effectiveness of HJA in the treatment of elderly FNF, due to the fact that DAA approach involves the neuromuscular interface and accords with the idea of soft tissue retention and enhanced recovery after surgery. However, there is still a lack of unified understanding of standard technique and procedure of DAA-HJA in the treatment of elderly FNF. Therefore, relevant experts from the Hip Joint Group of Chinese Orthopedics Association of Chinese Medical Association, Youth Arthrology Group of Orthopedic Committee of PLA, Orthopedic Committee of Chongqing Medical Association, Branch of Orthopedic Surgeons of Chongqing Medical Doctor Association and Sport Medicine Committee of Chongqing Medical Association were organized to formulate the " Chinese expert consensus on the technical standard of direct anterior hip arthroplasty for elderly femoral neck fracture ( version 2023)" based on evidence-based medicine. This consensus mainly proposed 13 recommendations covering indications, surgical plans, prosthesis selections, surgical techniques and processes, and postoperative management of DAA-HJA in elderly patients with FNF, aiming to promote standardized, systematic and patient-specific diagnosis and treatment to improve the functional prognosis of the patients.

Cardiometabolic disease (CMD), characterized with metabolic disorder triggered cardiovascular events, is a leading cause of death and disability. Metabolic disorders trigger chronic low-grade inflammation, and actually, a new concept of metaflammation has been proposed to define the state of metabolism connected with immunological adaptations. Amongst the continuously increased list of systemic metabolites in regulation of immune system, bile acids (BAs) represent a distinct class of metabolites implicated in the whole process of CMD development because of its multifaceted roles in shaping systemic immunometabolism. BAs can directly modulate the immune system by either boosting or inhibiting inflammatory responses via diverse mechanisms. Moreover, BAs are key determinants in maintaining the dynamic communication between the host and microbiota. Importantly, BAs via targeting Farnesoid X receptor (FXR) and diverse other nuclear receptors play key roles in regulating metabolic homeostasis of lipids, glucose, and amino acids. Moreover, BAs axis per se is susceptible to inflammatory and metabolic intervention, and thereby BAs axis may constitute a reciprocal regulatory loop in metaflammation. We thus propose that BAs axis represents a core coordinator in integrating systemic immunometabolism implicated in the process of CMD. We provide an updated summary and an intensive discussion about how BAs shape both the innate and adaptive immune system, and how BAs axis function as a core coordinator in integrating metabolic disorder to chronic inflammation in conditions of CMD.

Objective:To investigate the effect of flap combined with 3D printed microporous titanium(tantalum)prosthesis in the treatment of lower extremity soft tissue defect with large bone defect.Methods:From January 2019 to December 2020, 2 patients with large soft tissue defects on dorsal foot together with large metatarsal bone defect and 4 patients with soft tissue defects of calf with large tibial bone defect were treated. The areas of soft tissue defect were 5.0 cm×8.0 cm-15.0 cm×10.0 cm. The length of the bone defect were 3.8 cm to 7.0 cm, 5.75 cm in average. In the first stage, metatarsal bone defect or tibial bone defect was filled with vancomycin blended bone cement, meanwhile, soft tissue defect was repaired with anterolateral femoral flap(ALTF) with vascular anastomosis in 2 cases of feet, and local fascia flap was trans-positioned in 4 cases of lower extremity defects. The sizes of repairing flap were 6.0 cm×8.5 cm-16.0 cm×11.0 cm. Two to 7 months after the initial surgery, the customer designed microporous titanium prostheses were used(5 cases with microporous titanium and 1 with microporous tantalum) to repair the bone defects. The wound healing, the integration of metatarsal and tibial fractures with 3D printed microporous titanium(tantalum) prostheses, and the walking condition were observed after surgery. The follow-up lasted from 6 to 25 months, with an average of 12.7 months.Results:The wound healing in 5 patients was good. The patients stood on the foot in 2 months after surgery, started to walk with the assistance of crutch in 3 months after surgery, and took walk without assistance in 5-6 months after surgery. Good osseous integration were achieved. One diabetic patient had infection of foot wound 3 months after surgery. After removal of microporous titanium prosthesis and replacement of vancomycin blended interstitial substance of bone cement, the wound healed and the patient resumed walking.Conclusion:It is an effective method to encourage the patients to take early ambulation after the surgery for lower extremity soft tissue defect with large bone defect that was repaired by a flap and 3D printed microporous titanium(tantalum)prosthesis. Further observations are required to investigate the long-term efficacy, and the reduction of prosthesis infection rate requires further exploration.

Background and Objectives: Human umbilical cord mesenchymal stem cells (HUC-MSCs) are promising candidates for cell-based therapy in regenerative medicine or other diseases due to their superior characteristics, including higher proliferation, faster self-renewal ability, lower immunogenicity, a noninvasive harvest procedure, easy expansion in vitro, and ethical access, compared with stem cells from other sources. Methods: and Results: In the present study, we knocked down the expression of SOX9 in HUC-MSCs by lentivirus interference and found that knockdown of SOX9 inhibited the proliferation and migration of HUC-MSCs and influenced the expression of cytokines (IL-6 and IL-8), growth factors (GM-CSF and VEGF) and stemness-related genes (OCT4 and SALL4). In addition, the repair effect of skin with burn injury in rats treated with HUC-MSCs transfected with sh-control was better than that rats treated with HUC-MSCs transfected with shSOX9 or PBS, and the accessory structures of the skin, including hair follicles and glands, were greater than those in the other groups. We found that knockdown of the expression of SOX9 obviously inhibited the expression of Ki67, CK14 and CK18. Conclusions In conclusion, this study will provide a guide for modifying HUC-MSCs by bioengineering technology in the future.

Objective: To analyze the clinical characteristics of cases of novel coronavirus pneumonia and a preliminary study to explore the relationship between different clinical classification and liver damage. Methods: Consecutively confirmed novel coronavirus infection cases admitted to seven designated hospitals during January 23, 2020 to February 8, 2020 were included. Clinical classification (mild, moderate, severe, and critical) was carried out according to the diagnosis and treatment program of novel coronavirus pneumonia (Trial Fifth Edition) issued by the National Health Commission. The research data were analyzed using SPSS19.0 statistical software. Quantitative data were expressed as median (interquartile range), and qualitative data were expressed as frequency and rate. Results: 32 confirmed cases that met the inclusion criteria were included. 28 cases were of mild or moderate type (87.50%), and four cases (12.50%) of severe or critical type. Four cases (12.5%) were combined with one underlying disease (bronchial asthma, coronary heart disease, malignant tumor, chronic kidney disease), and one case (3.13%) was simultaneously combined with high blood pressure and malignant tumor. The results of laboratory examination showed that the alanine aminotransferase (ALT), aspartate aminotransferase (AST), albumin (ALB), and total bilirubin (TBil) for entire cohort were 26.98 (16.88 ~ 46.09) U/L and 24.75 (18.71 ~ 31.79) U/L, 39.00 (36.20 ~ 44.20) g/L and 16.40 (11.34- ~ 21.15) mmol/L, respectively. ALT, AST, ALB and TBil of the mild or moderate subgroups were 22.75 (16.31- ~ 37.25) U/L, 23.63 (18.71 ~ 26.50) U/L, 39.70 (36.50 ~ 46.10) g/L, and 15.95 (11.34 ~ 20.83) mmol/L, respectively. ALT, AST, ALB and TBil of the severe or critical subgroups were 60.25 (40.88 ~ 68.90) U/L, 37.00 (20.88 ~ 64.45) U/L, 35.75 (28.68 ~ 42.00) g/L, and 20.50 (11.28 ~ 25.00) mmol/L, respectively. Conclusion The results of this multicenter retrospective study suggests that novel coronavirus pneumonia combined with liver damage is more likely to be caused by adverse drug reactions and systemic inflammation in severe patients receiving medical treatment. Therefore, liver function monitoring and evaluation should be strengthened during the treatment of such patients.
