Abstract
BACKGROUND Osteoarthritis (OA) is the most prevalent form of degenerative whole-joint disease. Before the final option of knee replacement, arthroscopic surgery was the most widely used joint-preserving surgical treatment. Emerging regenerative therapies, such as those involving platelet-rich plasma, mesenchymal stem cells, and microfragmented adipose tissue (MFAT), have been pushed to the forefront of treatment to prevent the progression of OA. Currently, MFAT has been successfully applied to treat different types of orthopedic diseases. AIM To assess the efficacy and safety of MFAT with arthroscopic surgery in patients with knee OA (KOA). METHODS A randomized, multicenter study was conducted between June 2017 and November 2022 in 10 hospitals in Zhejiang, China. Overall, 302 patients diagnosed with KOA (Kellgren-Lawrence grades 2-3) were randomized to the MFAT group (n = 151, were administered MFAT following arthroscopic surgery), or the control group (n = 151, were administered hyaluronic acid following arthroscopic surgery). The study outcomes were changes in the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, the visual analog scale (VAS) score, the Lequesne index score, the Whole-Organ Magnetic Resonance Imaging Score (WORMS), and safety over a 24-mo period from baseline. RESULTS The changes in the WOMAC score (including the three subscale scores), VAS pain score, and Lequesne index score at the 24-mo mark were significantly different in the MFAT and control groups, as well as when comparing values at the posttreatment visit and those at baseline (P < 0.001). The MFAT group consistently demonstrated significant decreases in the WOMAC pain scores and VAS scores at all follow-ups compared to the control group (P < 0.05). Furthermore, the WOMAC stiffness score, WOMAC function score, and Lequesne index score differed significantly between the groups at 12 and 24 mo (P < 0.05). However, no significant between-group differences were observed in the WORMS at 24 mo (P = 0.367). No serious adverse events occurred in both groups. CONCLUSION The MFAT injection combined with arthroscopic surgery treatment group showed better mid-term clinical outcomes compared to the control group, suggesting its efficacy as a therapeutic approach for patients with KOA.

Abstract
Ankylosing spondylitis (AS) is a chronic inflammatory disease mainly affecting the sacroiliac joints, spine and peripheral joints. In China, standardized diagnosis and treatment of AS is still to be popularized. Based on the evidence and guidelines from China and other countries, Chinese Rheumatology Association developed standardization of diagnosis and treatment of AS. The purposes are: (1) to standardize the diagnosis and evaluation of AS; (2) to promote rational use of non-steroidal anti-inflammatory drugs, biological as well as traditional disease modifying anti-rheumatic drugs, so as to improve the patient's quality of life.

Abstract
Objective To observe expression of CD38, a key modulator of nicotinamide dinucleotide (NAD+) metabolism in mice with knee osteoarthritis, and protective effect of CD38 inhibition during the osteoarthritis (OA) development. Method The destabilization of the medial meniscus (DMM) model was performed in mice to mimic the process of OA. Immunofluorescence of CD38 was performed to evaluate its response during the OA process. Limb bud‐derived mesenchymal cells were isolated for micromass culture. 100 nM or 1 μM CD38 inhibitor (78c) treatment for 14 days and CD38 sgRNA infection were then used to explore the effects of chondrogenic differentiation via Alcian blue staining. The expressions of chondrogenic markers were detected using RT‐PCR and Western blot. To explore the protective effect of CD38 inhibitor on cartilage degradation during OA in vivo, a CD38 inhibitor was injected into the knee joint after DMM operations. Micro‐CT analysis and Safranin O‐fast green staining were used to evaluate subchondral bone micro‐architecture changes and cartilage degeneration. Results Compared to the control group, the CD38 expression in superficial cartilage was obviously increased in DMM group (P < 0.05). During the normal chondrogenic differentiation, the extracellular matrix formed and expression of Sox9, Col2, aggrecan increased apparently while CD38 expression decreased, which could be reversed with ablation of CD38 in limb bud‐derived mesenchymal cells. Consistent with findings in vitro, CD38 blockage via CD38 inhibitor injection protected against osteosclerosis in medial subchondral bone and cartilage degeneration in DMM‐induced experimental mice. Compared to the Sham group, DMM mice showed significantly increased values of BV and BV/TV in subchondral bone (P < 0.05) and Mankin score, which could be rescued by 78c treatment (P < 0.05). Also the CD38 inhibitor contributed to homeostasis of anabolism and catabolism by upregulating Sox9, Col2, aggrecan and downregulating Runx2, Col10 and Mmp13. Conclusion This study primarily implicates CD38 as an important regulator of chondrogenic differentiation. Inhibition of CD38 demonstrated protection against cartilage degeneration, which suggests that CD38 could be a potential therapeutic target for OA.

Abstract
Steroid-associated necrosis of the femoral head (SANFH) is one of the most common and refractory chronic diseases with increasing incidence. The typical pathological changes of SANFH include decreased osteogenic differentiation, enhanced intramedullary adipocytes deposition and impaired osseous circulation. In this study, we investigated the effects and potential mechanisms of Platelet-rich plasma (PRP) on SANFH. Sixty Sprague-Dawley rats were randomly divided into the control, PRP donor, model, and PRP groups. Compared to the model group, PRP treatment significantly increased the hemorheological indexes and serum levels of bone gla-protein (BGP) and vascular endothelial growth factor (VEGF), while decreased the levels of triglyceride (TG) and total cholesterol (TC). Meanwhile, Micro-CT and histopathological stain (Hematoxylin-eosin and Alcian blue-hematoxylin/orange G staining) were performed on the femoral head for morphological and histopathological evaluation, indicating that bone trabecular microstructure and bone mineral density (BMD) were significantly improved after PRP treatment. Immunohistochemical analysis revealed that PRP remarkably up-regulated the expression of osteogenic markers including β-catenin and alkaline phosphatase (ALP), angiogenic markers containing VEGF and platelet endothelial cell adhesion molecule-1 (CD31), while down-regulated adipogenic markers involving fatty acid-binding protein (FABP-4), and peroxisome proliferator-activated receptor gamma (PPAR-γ) in SANFH rat models. In summary, for the first time, PRP was demonstrated to prevent the development of SANFH through stimulating bone formation and vascularization as well as retarding adipogenesis.

Abstract
Recently, the joint replacement has gradually become a common operation of orthopedics. It's also the hot spot in current investigations. The increasing number of reports about the 3D printing technology such as patient-specific instrumentation(PSI) is applied to hip and knee replacement. It plays an important role in supporting operation especially for complex cases. However, it is still at the primary stage. This article reviews the relevant literature, analyzes and collates the research status of the application of 3D printing PSI in total knee arthroplasty, and summarizes its effectiveness in the application of knee arthroplasty from the aspects of individual preoperative planning, intraoperative operation and postoperative functional recovery, especially complex knee surgery such as obesity and knee deformity. The necessity of clinical application is discussed, and the existing problems and controversies in the current clinical application are summarized in order to provide references for the future research direction and clinical application.

Abstract
As an important component of articular cartilage, type IX collagen plays an important role in regulating homeostasis of bone and cartilage. The mutation or deletion of gene could disequilibrate homeostasis leads to deformity of corresponding bone and joint, and finally causes multiple epiphyseal dysplasia. Moreover, anatomic variation also leads to biomechanics change of corresponding functional unit, combine with micro-environment change caused by change of genes, osteoarthritis and disc degeneration were occurred under the function of stress over and over again. In addition, lack of type IX collagen could effect repair of articular cartilage, intervertebral disc tissue injury. However, musculoskeletal diseases related with type IX collagen has so much not limited this, the reports about it is less for lack of evidence, and need further work to study. Clear relationship of type IX collagen and its disease could provide an effective diagnostic method, and develop a new pathway for follow-up treatment.

Abstract
OBJECTIVE To investigate the clinical characteristics, the medicine application and to evaluate the disease activity in patients with osteoarthritis (OA) in China. METHODS This was a cross-sectional study. Totally 1 066 cases of OA from 40 hospitals in China from April to October 2017 were retrospectively enrolled. Demographic characteristics, clinical data, medicine application, and joint function were evaluated. All the data were analyzed by SPSS software 19.0. t test, Mann-Whitney U test and chi-square test were used for statistical analysis. RESULTS In the 1 066 cases, the male-to-female ratio was 1:3.6 and the average age was (61.9±11.0) years, with an age range from 36 to 94 years. The incidence of knee OA, hip OA, and hand OA were respectively 81.9% (873/1 066), 14.1% (150/1 066), and 36.3% (387/1 066). In the study, 242 (22.7%) cases had two kinds of joint areas involved and three joint areas were involved in 51 cases (4.8%), and 56.6% (603/1 066) of the patients used more than one kind of non-steroid anti-inflammatory drugs (NSAIDs) while 61.2% (652/1 066) used disease modifying osteoarthritis drugs (DMOADs), including glucosamine (37.5%, 400/1 066), chondroitin sulfate (2.0%, 21/1 066), diacetate (5.9%, 63/1 066), and the combination of these drugs (15.8%, 168/1 066). 8.6% (92/1 066) patients only took analgesics to relieve the pain, not using any kind of NSAIDs or DMOADs. And 232 patients (21.7%) had intra-articular injections, including 9.2% (98/1 066) sodium hyaluronate, 4.5%(48/1 066) glucocorticoid, and 8.1% (86/1 066) combination of the two drugs. The proportion of the patients taking topical drugs accounted for 26.5% (283/1 066) and physical therapy accounted for 15.8% (168/1 066). Compared with those who suffered from knee OA, the patients who suffered from hip OA had more severe disease assessment. Moreover, there were significant differences in pain (Z=-7.625, P<0.001), morning stiffness (Z=-6.229, P<0.001), and joint function (Z=-6.777, P<0.001) between the two groups of the patients who suffered from knee or hip OA with The Western Ontario and McMaster Universities (WOMAC) osteoarthritis index. Furthermore, patients with hip OA took more analgesics (χ2=24.838, P<0.001). CONCLUSION Oral NSAIDs and DMOADs are wildly used in patients with OA in China. However, the treatment of some patients still need to be improved. Patients with hip OA are more seriously ill and require aggressive treatment.

Abstract
As a traditional concept of Chinese medicine (CM), the theory of "Shen (Kidney) controlling bones" has been gradually proven. And in modern allopathic medicine, the multiple mechanisms of bone growth, development and regeneration align with the theory. Shen deficiency as a pathological condition has a negative effect on the skeleton of body, specifically the disorder of bone homeostasis. Present studies indicate that Shen deficiency shares a common disorder characterized by dysfunction of hypothalamic-pituitary-adrenal (HPA) axis. HPA axis may be an important regulator of bone diseases with abnormal homeostasis. Therefore, we posit the existence of hypothalamic-pituitary-adrenal-osteo-related cells axis: cells that comprise bone tissue (osteo-related cells) are targets under the regulation of HPA axis in disorder of bone homeostasis. Chinese herbs for nourishing Shen have potential in the development of treatments for disorder of bone homeostasis.

OBJECTIVE To investigate the effect of accumulated spinal axial biomechanical loading on mice lumbar disc and the feasibility of applying this method to establish a mice intervertebral disc degeneration model using a custom-made hot plate cage. In previous studies, we observed that the motion pattern of mice was greatly similar to that of humans when they were standing and jumping on their lower limbs. There is little data to demonstrate whether or not accumulated spinal axial biomechanical loading could induce intervertebral disc degeneration in vivo. METHODS Twenty-four 0-week-old mice were randomly divided into model 1-month and 3-month groups, and control 1-month and 3-month groups (n = 6 per group). The model groups was transferred into the custom-made hot plate cage three times per day for modeling. The control group was kept in a regular cage. The intervertebral disc samples of the L3 -L5 were harvested for histologic, molecular, and immunohistochemical studies after modeling for 1 and 3 months. RESULTS Accumulated spinal axial biomechanical loading affects the histologic, molecular, and immunohistochemical changes of mice L3- L5 intervertebral discs. Decreased height of disc and endplate, fissures of annulus fibrosus, and ossification of cartilage endplate were found in morphological studies. Immunohistochemical studies of the protein level showed a similar expression of type II collagen at 1 month, but a slightly decreased expression at 3 months, and an increased expression level of type X collagen and matrix metalloproteinase 13 (MMP13). Molecular studies showed that ColIIa1 and aggrecan mRNA expression levels were slightly increased at 1 month (P > 0.05), but then decreased slightly (P > 0.05). ColXa1, ADAMTS-5, and MMP-13 expression levels werer increased both at 1 and 3 months (P < 0.05). In addition, increased expression of Runx2 was observed. CONCLUSION Accumulated spinal axial loading provided by a custom-made hot plate accelerated mice lumbar disc and especially endplate degeneration. However, this method requires further development to establish a lumbar disc degeneration model.

Abstract
Esophagustype cervical spondylosis is easily misdiagnosed or missed diagnosed for its lower incidence. The pathological basis manily concerned with compression of osteophyte for esophageal and tracheal wall and local inflammatory reaction. The diagnosis of disease is generally not difficult. Especially dynamic esophagogram could not only show degree of cervical degeneration and osteophyte shape, but also could clearly observe location and degree of osteophytosis indenting esophageal and tracheal. Recently, the treatment of esophagustype cervical spondylosis has been the focus of attention. It is generally believed that conservative treatment could alleviate disease but could not cure it. More and more scholars tend to treat disease by surgical resection of osteophyte to relieve compression for esophagus, and clinical symptoms could obviously improved. However, long-term follow up is lack, and further follow-up effect is lack of powerful support, anddifferent treatment methods and surgical procedures are lack of comparative research.

Abstract
OBJECTIVE To explore the feasibility of passage, cryopreservation, and recovery of osteoclasts in order to develop new techniques facilitating osteoclast research. METHODS Passage of osteoclasts: adult male SD rat(SPF grade, weight of 250 g) was sacrificed and the abdominal aorta was exposed for blood draw. Monocytes isolated from peripheral circulation was treated with RANKL and M-CSF for 2 weeks. After formation of osteoclasts, they were trypsinized with pipetting, centrifuged, re-suspended with α-MEM containing RANKL and M-CSF, and cultured in 6 well-plates and 35 mm culture dishes. Freezing of osteoclasts: trypsinized osteoclasts were centrifuged and resuspended with DMSO, FBS, α-MEM (1:2:7), and were stored in liquid nitrogen(-196 °C). Recovery of osteoclasts: frozen osteoclasts were taken out of liquid nitrogen tank and thawed quickly at 37 °C in water bath. After wash with PBS, the cells were resuspended with α-MEM containing RANKL and M-CSF, and were cultured in 6 well dishes and 35 mm culture dishes. Meanwhile, cells were checked with inverted phase contrast microscope and observed in the live cell station for real time imaging. TRAP staining was performed 3 days after plating. RESULTS Trypsinization together with pipetting and shaking can detach the adherent osteoclasts, and the resuspended cells can be used for passage and storage in liquid nitrogen. The passaged cells became fully attached to the culture dishes in 2 hours, and the multinucleated feature could be clearly seen. The osteoclasts recovered from liquid nitrogen could completely spread out for 2 to 3 hours so that the multinucleated cells were clearly seen. These cells were still TRAP positive. CONCLUSIONS Although osteoclasts strongly adhere to the bottom of culture dishes, a large majority of the osteoclasts can be detached after appropriate digestion with trypsin, pipetting and shaking. These cells can be used for passage and cryopreservation. After recovering from liquid nitrogen, these cells still preserve the viability and the feature of osteoclasts. The results provide a new and powerful tool for future study of osteoclast biology.

Abstract
OBJECTIVE To observe the clinical significance of postoperative personalized antithrombotic therapy for patients with hemophilic arthritis (HA) patients after arthroplasty. METHODS From September 2005 to October 2013, 11 cases of arthroplasty for hemophilic arthritis in hip and knee total operation 14 times,including 1 case of double knees (calculated as one operation), operation in left knees 6 times, operation in right knees 5 times, 2 in hip. All the patients were male and the age ranged from 23 to 57 years old,with an average of (36.1 ± 11.0) years old; the average weight was (64.1 ± 8.9) kg. All the patients were preoperatively diagnosed and classified as hemophilic arthritis with the radiological images and laboratory tests. According to the function of joints, the risk of postoperative venous thromboembolism (VTE), and dynamic observation of Factor VIII:C (FVIII:C) activity, patients were treated with personalized antithrombus by adjusting the dosage of recombinant human coagulation factor VIII (Kogenate FS). All the patients were orderly divided into postoperatively distal joints moving group and none-moving group to observe the coagulation function. RESULTS The enrolled patients had no postoperative complication of VTE and pulmonary embolism (PE). The APTT and D-2 were different between two groups in the postoperative early stage. Length of hospital day was shorter in the moving group than none-moving group. CONCLUSION Because of the self-coagulation disorder, patients with HA tended to bleed. However it doesn't mean that there is no risk of postoperative thrombosis. Therefore,it's important to determine how to control the balance between postoperative antithrombus, hemostasis,and coagulation factor replacement therapy after arthroplasty for HA. Postoperative moving has proved helpful for HA, especially in reducing the risk of hemostasis and shortening the time in hospital.

Abstract
The aim of this study was to evaluate the effects of antibacterial peptide (ABP) sufficiency on cellular immune functions by determining the spleen cell cycle and apoptosis, peripheral blood T cell subsets, and T cell proliferation function in weaned piglets. A total of 90 piglets (Duroc × Landrace × Yorkshire) of both sexes were randomly allotted to 5 dietary treatments. Each treatment consisted of 3 replicates with 6 piglets per replicate. The dietary treatments consisted of the negative control (NC; basal diet), positive control (PC; basal diet supplemented with 400 mg/kg Astragalus polysaccharide), and ABP (basal diet mixed with 250, 500, and 1,000 mg/kg ABP). The experimental lasted for 28 d. Two piglets from each replicate were selected randomly for blood samples extraction from the jugular vein to obtain peripheral blood T cell subsets, and T cell proliferation function analysis was performed on d 32, 39, 46, and 53. Two piglets from each replicate were selected and euthanized to observe the spleen cell cycle and apoptosis on d 39 and 53. In ABP-sufficient piglets, the G0/G1 phase of the spleen cell cycle was much lower (P < 0.05) and the S and G2 + M phases and proliferation index (PI) were greater (P < 0.05) than in NC piglets. The percentage of apoptotic cells in the spleen significantly decreased under ABP sufficiency (P < 0.05). The proliferation function of peripheral blood T cells increased (P < 0.05) in ABP-sufficient piglets. Percentages of CD3 (+) and CD3 (+)CD4 (+) ratios (d 39, 46, and 53) and CD4 (+)CD8 (+) ratios (d 32, 39, 46, and 53) increased remarkably (P < 0.05) under ABP sufficiency compared with NC. These results suggest that ABP sufficiency could increase the T cell population and proliferation function of T cells and could induce decreased percentages of apoptotic cells. Overall, the cellular immune function was evidently improved in weaned piglets. We suggest optimal dosages of 500 mg/kg ABP for 4-wk addition and 1,000 mg/kg ABP for 2-wk addition.

Abstract
OBJECTIVE To compare biological characteristics between nucleus pulposus and annulus fibrosus cells in vitro model. METHODS Five New Zealand white rabbits (2 to 3 kg, either gender) were isolated nucleus pulposus and annulus fibrosus under sterilized condition, then cultured in nutrient solution with 15% FBS and DMEM/F12 (1:1) by enzyme digestion combined with tissue block method. When 90% cells fused, subcultring were performed. Cell morphology were observed by inverted phase contrast microscope, cell viability were detected by trypan blue staining, histological were observed by a toluidine blue and HE staining, cell proliferation were tested by MTT method, then the cell morphology, viability, proliferation between nucleus pulposus and annulus fibrosus were compared. RESULTS There were no obviously differences between nucleus pulposus and annulus fibrosus in original and the first strain. Physalides were appeared in annulus fibrosus on the second generation. The strapping time was later, and activity was lower in nucleus pulposus than annulus fibrosus. The growth of cell proliferation in nucleus pulposus was lower than annulus fibrosus from the ninth day. CONCLUSION The cell activity in annulus fibrosus is higher than nucleus pulposus. Digenerative disc disease may caused by recession of nucleus pulposus,local biomechnical changes, furether caused structure change and function loss of annulus fibrosus.

Abstract
PURPOSE The authors sought to quantitatively analyse enhancement characteristics of pancreatic insulinomas in different phases and determine the value of multidetector-row computed tomography (CT) for detecting insulinomas. MATERIALS AND METHODS Forty-six patients with surgically proven insulinomas diagnosed between 2002 and 2007 were retrospectively reviewed. These patients underwent single-phase (group 1) or dual-phase (group 2) helical CT scanning. RESULTS Sensitivity for detecting insulinomas in group 2 was superior to that in group 1 (p<0.05).The sensitivity for insulinoma detection in the arterial phase was superior to that in the portal-venous phase (p<0.05). The mean attenuation values of the insulinomas and normal pancreas during the unenhanced arterial and portal-venous phases were, respectively, 40.5+/-8.75 HU (Hounsfield units), 114.48+/-27.30 HU, 112.19+/-19.52 HU and 44.56+/-6.48 HU, 81.16+/-15.22 HU, 90.54+/-13.80 HU, and there was statistical difference between them (p=0.000). The contrast enhancement of insulinomas in the arterial and portal-venous phases was 74.03+/-29.51 HU and 70.90+/-21.93 HU, respectively, and there was no statistical difference between them (p=0.499). The tumour to normal-pancreas attenuation differences in the arterial and portal-venous phases were respectively 33.32+/-20.96 HU and 20.58+/-16.32 HU, respectively, and there was statistical difference between them (p=0.011). CONCLUSIONS Dual-phase CT has a promising sensitivity in detecting pancreatic insulinomas. The acquisition of images in the arterial phase is more helpful for detecting insulinomas.

Abstract
The HIV-1 envelope glycoprotein surface subunit gp120 is an attractive target for molecular intervention. This is because anti-HIV-1 gp120 neutralizing antibodies display the potential ability to inhibit HIV-1 infection. The present investigation describes the construction of a genetically engineered single chain antibody (scFv102) against HIV-1 gp120, its expression and functional evaluation. The parental hybridoma cell line (102) produces an immunoglobulin directed against the conserved CD4-binding region of gp120. cDNAs encoding the variable regions of the heavy (V(H)) and light (V(L)) chains were prepared by reverse transcription PCR and linked together with an oligonucleotide encoding a linker peptide (Gly(4)Ser)(3) to produce a single chain antibody gene. The resulting DNA construct was cloned into a prokaryotic expression vector (pET28) and recombinant scFv102 was expressed in Eserichia coli as an insoluble protein. The denatured scFv102 was refolded and purified by immobilized metal ion affinity chromatography. Purified scFv102 had the same specificity as the intact IgG in immuno-blotting assays and immuno-fluorescence (IF) detection, but ELISA analyses demonstrated the affinity of scFv102 to be 5-fold lower than that of the parental monoclonal antibody. In neutralization assays, scFv102 at concentrations lower than 40 microg/ml exhibited efficient interference with viral replication and inhibition of viral infection (90%) across a range of primary isolates of subtype B HIV-1. These results suggest that the constructed anti-HIV-1 gp120 scFv102 has good biological activity and can potentially be used for in vitro diagnostic and in vivo therapeutic applications.
