Abstract
PURPOSE The present study aimed to assess the clinical efficacy and imaging results of reconstruction of the medial patellofemoral ligament through a double bundle of single patellar tract and quadriceps tendons combined with medial displacement of lateral hemi-tibial tuberosity for treating low-grade recurrent patella dislocation. METHODS Twenty-three patients with recurrent patellar dislocation, including ten males and 13 females, with 23 knee joints were enrolled according to the relevant criteria. Reconstruction of the medial patellofemoral ligament was performed through a double bundle of a single patellar tract and quadriceps tendons combined with medial displacement of lateral hemi-tibial tuberosity. Knee function was evaluated using visual analog scale (VAS) score, International Knee Documentation Committee (IKDC) score, Lysholm score, Tegner score, and Kujala score at pre- and postoperative stages. Patellar stability was assessed by CT scans measuring tibial tuberosity-trochlear groove (TT-TG) distance, lateral patella displacement (LPD), congruence angle (CA), and patellar tilt angle (PTA). RESULTS All 23 patients were effectively followed up for 13-28 months (mean: 21.91 ± 4.14 months). At the last follow-up, the postoperative VAS score, IKDC score, Lysholm score, Tegner score, and Kujala score of 23 patients were 1.13 ± 0.82, 87.35 ± 3.17, 90.22 ± 1.28, 4.35 ± 0.65, and 89.26 ± 1.96, respectively, as compared to the preoperative values of 5.91 ± 1.13, 30.96 ± 5.09, 30.30 ± 2.98, 1.26 ± 0.62, and 27.87 ± 3.46, respectively, and these differences were statistically significant (P < 0.001). At the last follow-up, the postoperative TT-TG, LPD, CA, and PTA values of the 23 patients were 8.80 ± 1.85 mm, 6.01 ± 1.77 mm, 11.32 ± 6.18°, and 9.35 ± 2.88°, respectively, compared to the preoperative values of 18.77 ± 1.74 mm, 14.90 ± 4.07 mm, 37.82 ± 5.71°, and 23.58 ± 3.24°, respectively, and the differences were statistically significant (P < 0.001). No relevant complications were observed in the 23 patients. CONCLUSIONS Reconstruction of the medial patellofemoral ligament through a double bundle of a single patellar tract and quadriceps tendons combined with medial displacement of lateral hemi-tibial tuberosity for treating low-grade recurrent patella dislocation showed satisfactory medium-term efficacy, and further investigations are required to confirm the long-term efficacy of this approach.

Abstract
A study was conducted on rural women of childbearing age aged 20-49 who underwent the National Free Preconception Health Examination Project (NFPHEP)in Yunnan Province from 2013 to 2019. Descriptive analysis was conducted to determine the negative rate of IgG antibodies against the rubella virus and its differences among various socio-demographic characteristics. Among the 1 511 203 study subjects, the negative rate of IgG antibodies against the rubella virus was 24.36%. Only 2.64% of the population had received rubella virus vaccine. The negative rate of IgG antibodies among rural childbearing-age women in the preconception period in Yunnan Province decreased with age and educational level (Ptrend<0.001). The negative rate of IgG antibodies in ethnic minority women of childbearing age in the preconception period (25.19%) was higher than that of Han women (23.88%). Among the 22 ethnic groups with over 1 000 participants, the negative rates of IgG antibodies in women of childbearing age from the Blang (32.85%), Bouyei (31.03%), Zhuang (31.01%), and Miao (30.70%) ethnic groups were higher than those of women from other ethnic groups. Among the 16 states (cities) in Yunnan Province, the negative rate of IgG antibodies in pregnant women of childbearing age in Wenshan Zhuang and Miao Autonomous Prefecture (38.06%) and Lincang City (32.63%) was higher than that in other states (cities). The negative rate of serum IgG antibodies in women who reported having received rubella virus vaccine (18.60%) was lower than that in other non-vaccinated populations (24.52%). The proportion of rural women of childbearing age in Yunnan Province who were susceptible to the rubella virus before pregnancy was still high. It is necessary to promote rubella vaccination among people susceptible to rubella, especially pregnant women, to prevent rubella virus infection and reduce the incidence rate and disease burden of rubella people.

Abstract
We investigated the potential involvement of pyroptosis, a proinflammatory form of regulated cell death, in rheumatoid arthritis (RA). Synovial fluid, synovial tissues and/or serum were compared among 32 patients with RA, 46 patients with osteoarthritis (OA) and 30 healthy controls. Samples were assayed for interleukin (IL)-1β, IL-18 and lactate hydrogenase (LDH). Synovial expression of NLRP3, caspase-1 and cleaved gasdermin D (GSDMD) was assayed using immunohistochemistry and multiplex immunohistochemistry. Patients with RA showed significantly higher levels of IL-1β and IL-18 in synovial fluid than patients with OA, and significantly higher levels of both cytokines in serum than healthy controls. RA was associated with higher levels of LDH in synovial fluid than OA. Among patients with RA, levels of IL-1β, IL-18 and LDH were significantly higher in synovial fluid than in serum, and the levels in synovial fluid positively correlated with disease activity and inflammation. Synovial cells, particularly macrophages, showed upregulation of NLRP3, caspase-1 and cleaved GSDMD in RA compared to OA. Our results implicate pyroptosis in the pathogenesis of RA, perhaps as a driver of local inflammation in joints.

Abstract
BACKGROUND The efficacy and safety of tranexamic acid (TXA) in reducing blood loss following total knee arthroplasty (TKA) in patients with osteoarthritis have been widely confirmed. However, there is still a paucity of the evidences regarding the effectiveness of TXA in patients with rheumatoid arthritis (RA). The purpose of the study is to explore the efficacy and safety of intravenous TXA on blood loss and transfusion risk following simultaneous bilateral TKA (SBTKA) in patients with RA. METHODS As a multicenter retrospective study, a total of 74 patients diagnosed with RA who underwent SBTKA were assigned into TXA group (15 mg/kg intravenous TXA before skin incision, n = 50) and control group (no TXA use, n = 24). The primary outcomes were total blood loss (TBL) and intraoperative blood loss (IBL). The secondary outcomes were hemoglobin (Hb) and hematocrit (Hct) drop on postoperative day 3, transfusion rate and volume, ambulation time, length of stay, hospitalization expenses and the incidence of complications. RESULTS The mean TBL, IBL and transfusion volume in TXA group were significantly lower than those in control group. The Hb and Hct drop on postoperative day 3 in control group were higher than those in TXA group (p<0.05). The similar trend was detected on transfusion rate, ambulation time and length of stay. The incidence of complications and hospitalization expenses did not differ significantly between the two groups (p>0.05). CONCLUSIONS TXA could effectively reduce blood loss, decrease transfusion risk, shorten ambulation time and length of stay following SBTKA in patients with RA, without increasing the risk of complications.

Abstract
Heterotopic ossification (HO), including hereditary and acquired HO, is the formation of extraskeletal bone in skeletal muscle and surrounding soft tissues. Acquired HO is often caused by range of motion, explosion injury, nerve injury or burns. Severe HO can lead to pain and limited joint activity, affecting functional rehabilitation and quality of life. Increasing evidence shows that inflammatory processes and mesenchymal stem cells (MSCs) can drive HO. However, explicit knowledge about the specific mechanisms that result in HO and related cell precursors is still limited. Moreover, there are no effective methods to prevent or reduce HO formation. In this review, we provide an update of known risk factors and relevant cellular origins for HO. In particular, we focus on the underlying mechanisms of MSCs in acquired HO, which follow the osteogenic program. We also discuss the latest therapeutic value and implications for acquired HO. Our review highlights the current gaps in knowledge regarding the pathogenesis of acquired HO and identifies potential targets for the prevention and treatment of HO.

Abstract
The participants in this study were 20-49 years old rural childbearing age people who received the National Free Preconception Health Examination Project (NFPHEP) in Yunnan Province during 2013 to 2019. The proportion of ABO and RhD blood groups among different ethnic groups and different areas were calculated. The proportion of 2 748 131 participants with blood group A phenotype was highest (32.60%), followed by O (30.60%), B (27.33%) and AB (9.47%). In the RhD blood system, the proportion of the RhD positivity (RhD+) and RhD negativity (RhD-) group were 99.29% and 0.71% respectively. The proportions blood groups were significantly different among ethnic groups and areas (all P<0.001). Among 18 ethnic groups with more than 3 000 participants, Yao (42.75%), Bouyei (40.58%) and Dai (40.37%) ethnic groups had higher proportion of blood group O phenotype than other ethnic groups. Wa ethnic groups had highest proportion of the A (40.15%) and AB phenotypes (11.23%). Miao ethnic group (34.70%) and Lahu ethnic group (34.42%) had higher proportion of blood group B phenotype than other ethnic groups. Wa ethnic group had the highest proportion of RhD-group (1.88%). In all 16 prefectures of Yunnan, the proportion of blood group O phenotype was highest in Xishuangbanna Dai Autonomous Prefecture (40.27%). Baoshan city (36.39%), Lincang city (36.22%) and Dali Bai autonomous prefecture (36.06%) had higher proportion of blood group A phenotype than other regions. Diqing Tibetan Autonomous Prefecture (30.83%) and Qujing city (30.48%) had higher proportion of blood group B phenotype than other areas, while Zhaotong city had a highest proportion of blood group AB phenotype (11.19%). The proportion of RhD-group was highest in Honghe hani and Yi nationality autonomous prefecture(1.37%). The A RhD+(39.36%), A RhD-(0.78%), AB RhD+(11.03%), AB RhD-(0.20%) and O RhD-(0.48%) blood groups were higher proportion in Wa ethnic group than in other ethnic groups (P<0.001).

Abstract
BACKGROUND Muscle injury and concomitant bone injury are important drivers to induce heterotopic ossification (HO). However, the related roles of muscle and concomitant bone injury in HO formation are still unclear. This study aims to develop a mouse model through the combination of hindlimb amputation (Am) and cardiotoxin (CTX) injection to investigate the mechanism of HO formation. METHOD The mice were randomly divided into Am group (Am of right hindlimb, n = 12), CTX group (CTX injection in the calf muscle of left hindlimb, n = 12) and Am + CTX group (the combination of Am of right hindlimb and CTX injection of left hindlimb, n = 18). MicroCT was used to evaluate the incidence of HO. Histology was used to investigate the progression of HO. RESULTS The MicroCT showed that only Am or CTX injection failed to induce HO while the combination of Am and CTX injection successfully induced HO. The incidence of HO was significant in Am + CTX group on day 7 (0% vs 0% vs 83.3%, p = 0.001) and day 14 (0% vs 0% vs 83.3%, p = 0.048). HO was located on the left hindlimb where CTX was injected. Moreover, the bone volume and bone density on day 14 were higher than those on day 7 in Am + CTX group. Histology revealed the evidence of calcification and expression of osteogenic markers in calcification sites in Am + CTX group. CONCLUSION In summary, the combination of Am and CTX injection could successfully induce dystrophic calcification/HO, which occurs in the location of muscle injury.

Abstract
Spinons are well known as the elementary excitations of one-dimensional antiferromagnetic chains, but means to realize spinons in higher dimensions is the subject of intense research. Here, we use resonant x-ray scattering to study the layered trimer iridate Ba_{4}Ir_{3}O_{10}, which shows no magnetic order down to 0.2 K. An emergent one-dimensional spinon continuum is observed that can be well described by XXZ spin-1/2 chains with a magnetic exchange of ∼55 meV and a small Ising-like anisotropy. With 2% isovalent Sr doping, magnetic order appears below T_{N}=130 K along with sharper excitations in (Ba_{1-x}Sr_{x})_{4}Ir_{3}O_{10}. Combining our data with exact diagonalization calculations, we find that the frustrated intratrimer interactions effectively reduce the system into decoupled spin chains, the subtle balance of which can be easily tipped by perturbations such as chemical doping. Our results put Ba_{4}Ir_{3}O_{10} between the one-dimensional chain and two-dimensional quantum spin liquid scenarios, illustrating a new way to suppress magnetic order and realize fractional spinons.

Abstract
Sulfamates are widespread in numerous pharmacologically active molecules. In this paper, Silver/Bathophenanthroline catalyzed the intramolecular selective amination of primary C(sp3)−H bonds and secondary C(sp3)−H bonds of sulfamate esters, to produce cyclic sulfamates in good yields and with a high site-selectivity. DFT calculations revealed that the interaction between sulfamates and L10 makes the molecule more firmly attached to the catalyst, benefiting the catalysis reaction. The in vitro anticancer activity of the final products was evaluated in MCF-7 breast cancer cells.

Abstract
BACKGROUND The effect of body mass index (BMI) on blood loss in simultaneous bilateral total hip arthroplasty (SBTHA) was still undetermined. The purpose of the study was to evaluate the blood loss, transfusion and incidence of complications in normal, overweight, and obese patients undergoing SBTHA. METHODS A total of 344 patients following SBTHA were enrolled into this study. The patients were assigned into three groups on the basis of their BMI, including normal (BMI 18.0-24.9 kg/ m2), overweight (BMI 25.0-29.9 kg/ m2), or obese group (BMI ≥ 30.0 kg/ m2). The primary outcome was total blood loss (TBL), and secondary outcomes were intraoperative blood loss, drain volume, ratio of TBL and patient's blood volume (PBV), transfusion rate and volume, hemoglobin and hematocrit drop, length of stay, expenses, and complications. RESULTS The PBV and TBL increased significantly along with the elevated BMI (p < 0.001; p = 0.019, respectively). There was no significant difference in intraoperative blood loss, drain volume, transfusion volume, length of stay, expenses, or incidence of complications among the three groups. In addition, the transfusion rate in normal group was higher than that in overweight (58.3% vs 39.6%, p = 0.001) and obese group (58.3% vs 31.9%, p = 0.001). The maximum hemoglobin drop in obese group was the highest (p = 0.001). CONCLUSION Obesity could increase perioperative blood loss but not increase transfusion risk in the setting of SBTHA. Conversely, obese and overweight patients maybe have lower transfusion need compared with normal patients because of more blood volume. In addition, obesity did not affect the incidence of complications.

Abstract
Introduction Given the possibility of inadvertent bacterial contamination of salvaged blood, the use of cell salvage is relatively contraindicated in cases of reimplantation for chronic hip periprosthetic joint infection (PJI). However, there are no published data supporting this assertion. The purpose of the current study was to compare the reinfection rate and rate of postoperative allogeneic blood transfusion (ABT) in second-stage reimplantation for PJI with or without intraoperative cell salvage reinfusion. Materials and methods We identified 125 patients who underwent two-stage exchange for chronic hip PJI between November 2012 and April 2019. The groups of patients who had (n = 61) and had not (n = 64) received intraoperative cell salvage reinfusion were compared with respect to the curative infection-free rate. Moreover, we compared the need for postoperative ABT and identified independent factors associated with ABT using multiple regression analysis. Results The log-rank survival curve with an endpoint of infection eradication failure was not significantly different between the cell salvage group (98.4%, 95% CI 95.3–99.9%) and the control group (95.3%, 95% CI 90.2–99.9%) at one year (log rank, P = .330). The rates of postoperative ABT in the cell salvage group were significantly lower than those in the control group (11.5% vs 26.6%, P = .041). In multivariable models, patient age, body mass index, preoperative hemoglobin level, and intraoperative cell salvage were independent predictors of ABT exposure (P < .05). Conclusions The use of cell salvage during reimplantation in two-stage exchange for chronic hip PJI did not appear to increase the reinfection rate, while it significantly reduced the rate of postoperative allogeneic red blood transfusion. Greater age, lower BMI, lower preoperative hemoglobin, and non-intraoperative cell salvage reinfusion were associated with higher rate of allogeneic red blood transfusion.

Abstract
Background Characterizing the impacts of postoperative opioid use on total knee arthroplasty (TKA) patients may help optimize the pain management after TKA. The aim of the study is to examine the prevalence and risk factors for opioid use with an enhanced-recovery programme after primary TKA. Methods We identified 361 patients undergoing TKA, and separated those on the basis of whether to receive opioid use after surgery. Themultivariate logistic regression model was used to identify independent risk factors for opioid use after primary TKA. Length of stay (LOS) and postoperative complications were also recorded and compared. Results The prevalence of opioid use after primary TKA was 23.0%. The significant risk factor was the longer operative time (OR [odds ratio] = 1.017, 95% CI [confidence interval] = 1.001 to 1.032, p = 0.034) and the protective factor was the utilization of tranexamic acid(OR= 0.355, 95% CI = 0.161 to 0.780, p = 0.010). In addition, the LOS was longer in opioid group (p < 0.05). Conclusion Considering the adverse health effects of opioid use, strategies need to be developed to prevent persistent opioid use after TKA. Reducing operative time and the application of tranexamic acid could lower the risk of opioid use with an enhanced-recovery programme after primary TKA.

Abstract
The fabrication by Spark Plasma Sintering (SPS) of bulk high entropy ceramics from powders obtained by Self-propagating High temperature Synthesis (SHS) is addressed in this work. The effect produced by the introduction of 1 wt.% of graphite to the powders before SPS is investigated under different temperature conditions. The final density and composition of sintered (Hf0.2Mo0.2Zr0.2Ti0.2Ta0.2)B2 and (Hf0.2Mo0.2Zr0.2Ti0.2Nb0.2)B2 ceramics are found to be negatively affected by the presence of oxide impurities in the powders. While product composition can be progressively improved when the temperature is increased from 1800 to 1950 °C, residual porosities remain relatively high if using additive-free powders. In contrast, the introduction of 1 wt.%C markedly allows for oxides elimination by carbothermal reduction mechanism. Products consolidation is correspondingly enhanced so that relative densities of about 97% are attained. Other than the latter effect, surface oxides removal also makes powders more reactive, thus the synthesis of single-phase products is promoted. In particular, fully homogeneous (Hf0.2Mo0.2Zr0.2Ti0.2Ta0.2)B2 ceramics are obtained at relatively lower temperature conditions (1850 °C).

Abstract
From the perspective of improving the self-healing method in construction, a tubular healing fiber was adopted as a container to improve the encapsulation capacity, which was available using a micro-capsule as a container. Knowing the direction of the stresses to which structure members are subjected, this research investigated the influence of aligning tubular healing fibers parallel to intended stress into a cementitious composite to increase the self-healing capability. For that, a healing agent was encapsulated into a tubular healing fiber made with polyvinylidene of fluoride resin (PVDF). Then, the healing fiber was combined with steel fibers to align both fibers together parallel to the direction of an intended splitting tensile stress when subjected to a magnetic field in a cylindrical cementitious composite. The alignment method and the key point through which the alignment of the healing fibers could efficiently improve autonomic self-healing were investigated. Since the magnetic field is known to be able to drag steel to an expected direction, steel fibers were combined with the healing fibers to form a hybrid fiber that aligned both fibers together. The required mixture workability was investigated to avoid the sinking of the healing fibers into the mixture. The healing efficiency, according to the orientation of the healing fibers in the composite matrix, was evaluated through a permeability test and a repetitive splitting tensile test. The aligned healing fibers performed better than the randomly distributed healing fibers. However, according to the healing efficiency with aligned healing fibers, it was deduced that the observed decreasing effect of the container’s alignment on the specimen’s mechanical properties was low enough to be neglected.

Abstract
BACKGROUND Postoperative moderate and severe anemia (PMSA) has been a serious perioperative complication in primary total knee arthroplasty (TKA). However, the ideal cutoff values to predict PMSA is still undetermined. The aim of this study was (1) to identify the risk factors associated with PMSA and (2) to establish the cutoff values of preoperative hemoglobin (HB) associated with increased PMSA in primary TKA. METHODS We identified 474 patients undergoing primary TKA and separated those in which PMSA (HB was less than 110 g/L on postoperative day 1 and 3) was developed from those without PMSA. Multivariate logistic regression model was used to identify independent risk factors for PMSA. Area under the receiver-operator curve (AUC) was used to determine the best-supported preoperative HB cutoff across all the patients. RESULTS The PMSA rate in primary TKA was 53.2%. Significant risk factors were lower preoperative HB (OR [odds ratio] = 1.138, 95% CI [confidence interval] = 1.107-1.170, p < 0.001) and more intraoperative blood loss (OR = 1.022, 95% CI 1.484-4.598, p < 0.001). A preoperative HB cutoff value that maximized the AUC was 138.5 g/L for men (sensitivity: 79.4%, specificity: 75.0%) and 131.5 g/L for women (sensitivity: 74.7%, specificity: 80.5%), respectively. CONCLUSION We should recognize and consider the related risk factors to establish specific, personalized risk assessment for PMSA, including preoperative HB and intraoperative blood loss. Of these, preoperative HB was a referable tool to predict PMSA in primary TKA.

Abstract
Biomaterials that can harness the intrinsic osteogenic potential of stem cells offer a promising strategy to accelerate bone regeneration and repair. Previously, we had used methacrylated gelatin (GelMA)-based scaffolds to achieve bone formation from human mesenchymal stem cells (hMSCs). In this study, we aimed to further enhance hMSC osteogenesis by incorporating graphene oxide (GO)-based nanosheets into GelMA. In vitro results showed high viability and metabolic activities in hMSCs encapsulated in the newly developed nanocomposites. Incorporation of GO markedly increased mineralization within hMSC-laden constructs, which was further increased by replacing GO with silica-coated graphene oxide (SiGO). Mechanistic analysis revealed that the nanosheet enhanced the production, retention, and biological activity of endogenous bone morphogenetic proteins (BMPs), resulting in robust osteogenesis in the absence of exogenous osteoinductive growth factors. Specifically, the osteoinductive effect of the nanosheets was abolished by inhibiting the BMP signaling pathway with LDN-193189 treatment. The bone formation potential of the technology was further tested in vivo using a mouse subcutaneous implantation model, where hMSCs-laden GO/GelMA and SiGO/GelMA samples resulted in bone volumes 108 and 385 times larger, respectively, than the GelMA control group. Taken together, these results demonstrate the biological activity and mechanism of action of GO-based nanosheets in augmenting the osteogenic capability of hMSCs, and highlights the potential of leveraging nanomaterials such as GO and SiGO for bone tissue engineering applications.

Abstract
BACKGROUND Operating rooms (ORs) have strict requirements regarding cleanliness. While existing standards concerning the ventilation and staff guidelines are theoretically sufficient to subvert the threats posed by micro-organisms within the room, there exist potential sources of contamination due to human activity around the area. Studies exploring this influence of human activity on distribution of micro-organism contamination in ORs have relied on manual observations, or indirect methods such as number of door openings. AIM To utilize depth registration sensing technology to identify the activities of surgical staff and investigate their effect on the distribution of airborne micro-organism contamination in ORs. METHODS A mock surgical experiment was performed using a depth registration technique for the dynamic capturing of human presence and activity levels. Field measurements were carried out in one real OR to analyse its influence on the bacterial distribution in ORs with mixing ventilation system. FINDINGS Bacterial contamination levels tended to correlate with higher activity levels, albeit with some inconsistencies. The highest activity levels were around the surgical bed when the patient was placed, and around the instrument table during the surgical procedure. Locations with obstructions had the highest cfu densities, indicating that airflow patterns are important in such spaces. CONCLUSION Our activity monitoring methods demonstrate a novel means of studying the influences of human activities in hospital rooms.

Abstract
Objective: To determine the prevalence, epidemiological characteristics, and related factors of syphilis infection among rural childbearing age people to promote medical interventions on pre-pregnancy aristogenesis and syphilis infection in Yunnan province. Methods: The subjects in this study were 18-49-year-old rural couples of childbearing age from the National Free Preconception Health Examination Project in Yunnan province during 2013-2017. The descriptive study was carried out to determine the positive rate of Treponema pallidum specific antibody (TPsAb) and related sociodemographic characteristics. Results: The overall positive rate of TPsAb was 0.38% (8 204/2 160 455) in 2 160 455 rural childbearing age people in Yunnan. The positive rate of TPsAb was 0.39% (4 019/1 040 981) in men,higher than that in women (0.37%,4 185/1 119 474). The positive rate of TPsAb was highest in the age group 45-49 years (0.70%,158/22 511). The positive rate of TP antibody in the minority ethnic groups and Han ethnic groups appeared the same (0.38%). However,the highest positive rate of TPsAb was 0.77% (461/60 153) in Hani ethnic group among all the 17 minority ethnic groups. People with education level of primary education had the highest anti-TP positive rate (0.54%,2 327/431 275). The positive rate of TPsAb appeared the highest in Zhaotong (0.73%, 2 049/281 614) area among all the 16 prefectures of the province. The positive rate of TPsAb in the population from the impoverished regions (0.50%,2 963/590 039) was higher than in other disadvantaged areas (0.34%, 3 115/929 368) or areas with average income (0.33%,2 126/641 048). Significant differences appeared in the positive rate of TPsAb among populations of different ages, ethnic, education level, and economic level groups (trend χ2 test, P<0.001). Conclusions: The positive rate of TP antibody in rural childbearing age people in Yunnan was related to multi factors,including sex,age,ethnic group,education level,area, residence, and local economic situation. The positive rate of TPsAb was higher in men than in women. And people with elder age, lower education level, being Hani or Lahu ethnic group, and Zhaotong areas had higher TPsAb positive rates and higher syphilis infection risk.

Abstract
Objective: To explore the preliminary clinical efficacy and safety of calerizumab combined with apatinib in the treatment of patients with middle-advanced liver cancer whose disease has progressed after drug-eluting beads-transcatheter arterial chemoembolization (D-TACE). Methods: A retrospective analysis of 23 patients with advanced liver cancer after D-TACE who were treated with carrelizumab combined with apatinib from April 2019 to July 2020 at Lianyungang First People's Hospital was carried out. There were 15 males and 8 females with a mean age of (62±9) years. The clinical efficacy was evaluated according to the modified Response Evaluation Criteria in Solid Tumors (mRECRST), and treatment-related adverse events were analyzed after treatment. Results: All the patients received D-TACE therapy with an average of (2.6±1.0) times, TACE-refractory tumor was observed in 7 patients, and distant metastasis was seen in 6 patients. The objective response rates after combined treatment of 1 month and 3 months were 47.8% and 60.9%, respectively. Disease control rate (DCR) was 73.9% and 78.3%, respectively; median progression-free survival (mPFS) was 126 days. Among 18 patients with alpha fatoprotein (AFP)>200 μg/L, the values before and after treatment of 2 months was (497±117) μg/L and (80±19) μg/L, respectively (P<0.05). Among 9 patients of vascular endothelial growth factor (VEGF)>142.2 ng/L, the values before and after treatment of 2 months was (154±51) ng/L and (57±19) ng/L, respectively (P<0.05). The incidence of treatment-related adverse events was 87.0% (20/23). All adverse reactions did not exceed grade 3 and could be controlled by symptomatic supportive treatment or reducing the dose of apatinib,and the serum aspartate aminotransferase (AST) level after treatment of 3 months[(77±33) U/L] was higher than that before treatment [(45±26) U/L] (P<0.05). Conclusion: For patients with advanced liver cancer after D-TACE, the treatment of carrelizumab combined with apatinib is effective and the adverse reactions are controllable.

Abstract
OBJECTIVE Thymosin beta 4 (TB4) is the most abundant member of the beta-thymosin family in humans. The main physiological role of TB4 is the regulation of actin polymerization. TB4 is also involved in angiogenesis, cell survival, cell migration and fetal development. The aim of this study was to evaluate the activity of TB4 as a fetal growth promoter when administered during pregnancy. MATERIALS AND METHODS Our protocols have been carried out in full conformity with the rules and guidelines expected for this kind of trial. 10 pregnant mice received the same injection regimen. Only 6 of these 10 are part of this experiment because they were pregnant. At 10:00 a.m. on day E14 and E17 of gestation mice were weighed and treated with an intraperitoneal injection of TB4 (Regene RX, Rockville, MD, USA; 6 mg/kg in PBS). RESULTS The mothers treated with TB4 for two days precisely E14 and E17, showed a higher cranio-caudal length when compared to control newborns. At histology, maternal TB4 treatment was associated with more advanced development of lungs, heart, kidney, cerebral cortex and notochord. CONCLUSIONS Our study shows that TB4 administration during gestation may act as a powerful fetal growth promoter, by accelerating the development of newborn organs and tissues.

Abstract
BACKGROUND Without confirmation of the ventilation design conditions (typology and airflow rate), the common practice of identifying unidirectional airflow (UDAF) systems as equivalent to ultra-clean air ventilation systems may be misleading, but also any claims about the ineffectiveness of UDAF systems should be doubted. The aim of this review was to assess and compare ventilation system design conditions for which ultra-clean air (mean <10 cfu/m3) within 50 cm from the wound has been reported. Six medical databases were systematically searched to identify and select studies reporting intraoperative airborne levels expressed as cfu/m3 close to the wound site, and ventilation system design conditions. Available data on confounding factors such as the number of persons present in the operating room, number of door openings, and clothing material were also included. Predictors for achieving mean airborne bacteria levels within <10 cfu/m3 were identified using a penalized multivariate logistic regression model. Twelve studies met the eligibility criteria and were included for analysis. UDAF systems considered had significantly higher air volume flows compared with turbulent ventilation (TV) systems considered. Ultra-clean environments were reported in all UDAF-ventilated (N = 7) rooms compared with four of 11 operating rooms equipped with TV. On multivariate analysis, the total number of air exchange rates (P=0.019; odds ratio (OR) 95% confidence interval (CI): 0.66-0.96) and type of clothing material (P=0.031; OR 95% CI: 0.01-0.71) were significantly associated with achieving mean levels of airborne bacteria <10 cfu/m3. High-volume UDAF systems complying with DIN 1946-4:2008 standards for the airflow rate and ceiling diffuser size unconditionally achieve ultra-clean air close to the wound site. In conclusion, the studied articles demonstrate that high-volume UDAF systems perform as ultra-clean air systems and are superior to TV systems in reducing airborne bacteria levels close to the wound site.

Abstract
There is no consensus regarding the ideal dosages and times of multiple-dose intravenous tranexamic acid (IV-TXA) administration in total knee arthroplasty (TKA). This study aimed to assess the effect of six-dose IV-TXA with the total dosage more than 6 g on postoperative fibrinolysis and hidden blood loss (HBL) after primary TKA. A total of 175 patients were randomized into three groups to receive placebo (group A), or a single preoperative dose of 20 mg/kg IV-TXA (group B), or six-dose IV-TXA from the beginning of the procedure to subsequent 24 hours with the total dosage more than 6 g (group C). The calculated HBL, maximum hemoglobin (Hb) drop, transfusion rate, and the incidence of thromboembolic events were compared among groups. The levels of fibrinolysis parameters in plasma including fibrin(-ogen) degradation products (FDP) and D-dimer were measured at six time points from preoperatively to 3-month postoperative period. The mean HBL and maximum Hb drop in group C (515.51 ± 245.79 mL, and 2.06 ± 0.73 g/dL, respectively) were significantly lower than those in groups B (756.06 ± 226.79 mL, p < 0.001; and 2.77 ± 0.78 g/dL, p < 0.001, respectively) and A (987.65 ± 275.38 mL, p < 0.001; and 3.49 ± 0.86 g/dL, p < 0.001, respectively). Such differences were also detected between groups A and B (p < 0.001 and p < 0.001, respectively). The levels of FDP and D-dimer in plasma were lower in group C than those in groups B and A on postoperative 24, 48, 72 hours (p < 0.001 for all). No episode of transfusion occurred, and the incidence of thromboembolic events were similar among groups (p > 0.05). The administration of six-dose IV-TXA during the first 24 hours resulted in reduced HBL following TKA without a measured increase in thromboembolic events.

Abstract
Aims The efficacy and safety of intrawound vancomycin for preventing surgical site infection in primary hip and knee arthroplasty is uncertain. Methods A systematic review of the literature was conducted, indexed from inception to March 2020 in PubMed, Web of Science, Cochrane Library, Embase, and Google Scholar databases. All studies evaluating the efficacy and/or safety of intrawound vancomycin in patients who underwent primary hip and knee arthroplasty were included. Incidence of periprosthetic joint infection (PJI), superficial infection, aseptic wound complications, acute kidney injury, anaphylactic reaction, and ototoxicity were meta-analyzed. Results were reported as odds ratios (ORs) and 95% confidence intervals (CIs). The quality of included studies was assessed using the risk of bias in non-randomized studies of interventions (ROBINS-I) assessment tool. Results Nine studies involving 4,607 patients were included. Intrawound vancomycin was associated with lower incidence of PJI (30 patients (1.20%) vs 58 control patients (2.75%); OR 0.44, 95% CI 0.28 to 0.69) and simultaneous acute kidney injury (four patients (0.28%) vs four control patients (0.35%), OR 0.71, 95% CI 0.19 to 2.55). However, it did not reduce risk of superficial infection (four patients (0.67%) vs six control patients (1.60%), OR 0.60, 95% CI 0.17 to 2.12) and was associated with higher incidence of aseptic wound complications (23 patients (2.15%) vs eight in control patients (0.96%), OR 2.39, 95% CI 1.09 to 5.23). Four studies reported no anaphylactic reactions and three studies reported no ototoxicity in any patient group. Conclusion The current literature suggests that intrawound vancomycin used in primary hip and knee arthroplasty may reduce incidence of PJI, but it may also increase risk of aseptic wound complications.

Abstract
Aims Dystrophic calcification (DC) is the abnormal appearance of calcified deposits in degenerating tissue, often associated with injury. Extensive DC can lead to heterotopic ossification (HO), a pathological condition of ectopic bone formation. The highest rate of HO was found in combat-related blast injuries, a polytrauma condition with severe muscle injury. It has been noted that the incidence of HO significantly increased in the residual limbs of combat-injured patients if the final amputation was performed within the zone of injury compared to that which was proximal to the zone of injury. While aggressive limb salvage strategies may maximize the function of the residual limb, they may increase the possibility of retaining non-viable muscle tissue inside the body. In this study, we hypothesized that residual dead muscle tissue at the zone of injury could promote HO formation. Methods We tested the hypothesis by investigating the cellular and molecular consequences of implanting devitalized muscle tissue into mouse muscle pouch in the presence of muscle injury induced by cardiotoxin. Results Our findings showed that the presence of devitalized muscle tissue could cause a systemic decrease in circulating transforming growth factor-beta 1 (TGF-β1), which promoted DC formation following muscle injury. We further demonstrated that suppression of TGF-β signalling promoted DC in vivo, and potentiated osteogenic differentiation of muscle-derived stromal cells in vitro. Conclusion Taken together, these findings suggest that TGF-β1 may play a protective role in dead muscle tissue-induced DC, which is relevant to understanding the pathogenesis of post-traumatic HO.

Abstract
BACKGROUND In an enhanced recovery after surgery program, a growing number of orthopedists are reconsidering the necessity of tourniquet use in total knee arthroplasty (TKA). However, the impact of tourniquet use on transfusion rate and postoperative length of stay (PLOS) in TKA remains controversial. Therefore, we carried out a study to investigate the effect of tourniquet application in routine primary TKA on transfusion rate and PLOS. METHODS We analyzed data from 6325 patients who underwent primary unilateral TKA and divided them into two groups according to whether a tourniquet was applied during the procedure, and a tourniquet was used in 4902 and not used in 1423. The information for transfusion and PLOS was extracted from patients' electronic health records, and the data were analyzed with logistic and linear regression analyses. RESULTS Following TKA, the transfusion rate and PLOS were 14.52% and 7.72 ± 3.54 days, respectively, in the tourniquet group, and 6.47% and 6.44 ± 3.48 days, respectively, in the no-tourniquet group. After adjusting for the different related variables, tourniquet use was significantly correlated with a higher transfusion rate (risk ratio = 1.888, 95% confidence interval (CI) 1.449-2.461, P < 0.001) and a longer PLOS (partial regression coefficient (B) = 0.923, 95%CI 0.690-1.156, P < 0.001). CONCLUSIONS Our findings suggested that tourniquet use in routine primary TKA was related to a higher transfusion rate and a longer PLOS. The impact of tourniquet use on transfusion rate and PLOS should be taken into account in clinical practice.

Abstract
A simple variational argument is presented which indicates that the spin-orbit coupling in itinerant systems can be enhanced by strong electronic correlations. The importance of the enhancement in the formation of the giant magnetic anisotropy found in the metallic paramagnetic and magnetically ordered states of compounds containing transition metal and light actinide elements (such as tetragonal Sr2RhO4, Sr2IrO4, the cubic uranium monochalcogenides and tetragonal URu2Si2) is discussed.

Abstract
BACKGROUND The purpose of the study was to determine blood loss, transfusion risk, and incidence of immediate postoperative complications in normal, overweight, and I-II obese patients undergoing simultaneous bilateral total knee arthroplasty (SBTKA). METHOD We identified 1070 SBTKA procedures, and separated the patients into three groups on the basis of body mass index (BMI), including normal (BMI: 18.0-24.9 kg/m2), overweight (BMI: 25.0-29.9 kg/m2), and obese groups (BMI: ≥30.0 kg/m2). The primary outcome was total blood loss and secondary outcomes were dominant and hidden blood loss, transfusion rate and volume, hemoglobin (Hb) and hematocrit drop and other complications. RESULTS Patient's blood volume increased gradually among normal, overweight, and obese groups. There was no significant difference in blood loss or incidence of complications among the three groups, while the transfusion rate in the normal group was higher than that in overweight (36.0% vs 27.6%, p = 0.007) and obese groups (36.0% vs 24.6%, p = 0.006). In addition, the independent risk factors for complications among all groups following SBTKA included lower level of preoperative Hb (p = 0.040), general anesthesia (p = 0.002), drain use (p = 0.005), and transfusion (p < 0.001). CONCLUSIONS I-II obesity does not increase patient's blood loss, transfusion risk, or immediate postoperative complications following SBTKA. Obese and overweight patients may have lower transfusion needs compared with normal patients because of their higher basal blood volume. The risk factors for complications after SBTKA are lower level of preoperative Hb, general anesthesia, drain use and transfusion.

Abstract
OBJECTIVE The importance of circular RNAs in malignant tumors causes more attention in researchers. Hepatocellular carcinoma (HCC) is one of the most ordinary malignant tumors. Hsa_circ_0000285 was explored to identify how it functions in the metastasis of HCC. PATIENTS AND METHODS Real Time-quantitative Polymerase Chain Reaction (RT-qPCR) was utilized to detect hsa_circ_0000285 expression in HCC patients' tissues. Hsa_circ_0000285 lentivirus and shRNA was constructed for the transfection of HCC cells. Wound healing assay, transwell assay, and Matrigel assay were conducted to identify the function of hsa_circ_0000285 in HCC cells. Furthermore, mechanism assays were performed to uncover the interaction between hsa_circ_0000285 and miR-599. RESULTS Hsa_circ_0000285 was significantly higher-expressed in HCC samples compared to that in adjacent samples. The migrated length of HCC cells was reduced after hsa_circ_0000285 was silenced, while the migrated length of HCC cells was increased after hsa_circ_0000285 was overexpressed. Moreover, the number of migrated and invaded HCC cells was reduced after hsa_circ_0000285 was silenced, while the number of migrated and invaded HCC cells was increased after hsa_circ_0000285 was overexpressed. Moreover, RT-qPCR results revealed that miR-599 was downregulated via overexpression of hsa_circ_0000285, while miR-599 was upregulated via knockdown of hsa_circ_0000285. Further experiments showed that miR-599 was a direct target of hsa_circ_0000285 in HCC. CONCLUSIONS Hsa_circ_0000285 could enhance cell metastasis of HCC by targeting miR-599 and might be a potential therapeutic target in HCC.

Abstract
Objective To evaluate the risk factors for postoperative indwelling catheter following enhanced recovery after primary unilateral total knee arthroplasty (TKA) under general anesthesia. Methods Patients who underwent primary unilateral TKA under general anesthesia between January 2017 and August 2018 were enrolled in the study. Among them, 205 patients who met the selection criteria were included in the study, and the clinical data were collected, including gender, age, body mass index, preoperative range of motion, Hospital for Special Surgery (HSS) score, American Society of Anesthesiologists (ASA) score, disease type, comorbidity, hemoglobin, hematocrit, blood volume, length of operation and operation time, whether to keep drainage after surgery, intraoperative blood loss, total blood loss, and preoperative, intraoperative, postoperative fluid infusions, and total fluid infusion on the day of surgery, urine volume on the day of surgery. Univariate analysis and logistic regression analysis were used to screen the risk factors for postoperative indwelling catheter. Length of stay and incidences of complications (intermuscular vein thrombosis, deep vein thrombosis, pulmonary embolism, incision swelling and exudation, electrolyte disorder, nausea and vomiting, and urinary tract infection) were compared between the patients with or without indwelling catheter. Results Indwelling catheter occurred in 41 (20%) of 205 patients. Single factor analysis showed that the influence factors were age, gender, keeping drainage after surgery, total fluid infusion and urine volume on the day of surgery ( P<0.05). The multiple factors analysis showed that the males and more urine volume on the day of surgery were the significant risk factors for indwelling catheter after primary TKA ( P<0.05). In addition, postoperative length of stay was shorter and the incidence of urinary tract infection was lower in non-indwelling catheter group than in indwelling catheter group, showing significant differences ( P<0.05). Conclusion The male patients with more urine on the day of surgery have higher risk for indwelling catheter after primary unilateral TKA under general anesthesia with an enhanced recovery program.

Abstract
AIMS To explore the effect of intravenous tranexamic acid (IV-TXA) on inflammation and immune response following primary total knee arthroplasty (TKA). METHODS Primary TKA patients (n = 125) were randomized into the following four groups: group A to receive placebo; group B to receive a single dose of 20 mg kg-1 IV-TXA and 20 mg of intravenous dexamethasone (IV-DXM); group C to receive six doses of IV-TXA (total dosage > 6 g); and group D to receive six doses of IV-TXA combined with three doses of IV-DXM (total dosage = 40 mg). The primary outcomes were C-reactive protein (CRP) and interleukin (IL)-6 levels and the secondary outcomes were complement C3 and C4 and T-cell subset levels, which were measured preoperatively and at 24 h, 48 h, 72 h, and 2 weeks postoperatively. RESULTS The postoperative peak CRP and IL-6 levels in group C (93.7 ± 22.2 mg L-1, 108.8 ± 41.7 pg mL-1) were lower compared with those in group A (134.7 ± 28.8 mg L-1, P < 0.01; 161.6 ± 64.4 pg mL-1, P < 0.01). Groups B and D exhibited significantly lower CRP and IL-6 levels compared with groups A and C at 24 h, 48 h, and 72 h postoperatively (P < 0.05 for all). In group C, complement C3 and C4 levels were higher compared with those in group A at 48 h (0.967 ± 0.127 g L-1 vs. 0.792 ± 0.100 g L-1, P < 0.01; 0.221 ± 0.046 g L-1 vs. 0.167 ± 0.028 g L-1, P < 0.01) and 72 h (1.050 ± 0.181 g L-1 vs. 0.860 ± 0.126 g L-1, P = 0.01; 0.240 ± 0.052 g L-1 vs. 0.182 ± 0.036 g L-1, P < 0.01) postoperatively and CD3 and CD4 subset levels were higher compared with those in group B at 24 h postoperatively (66.78 ± 9.29% vs. 56.10 ± 12.47%, P < 0.05; 36.69 ± 5.78% vs. 28.39 ± 8.89%, P < 0.05). CONCLUSION Six doses of IV-TXA could attenuate the inflammatory effect, modulate the immune response, and reduce immunosuppression caused by DXM in patients after TKA.

Abstract
The effect of compression on the magnetic ground state of Sr_{2}IrO_{4} is studied with x-ray resonant techniques in the diamond anvil cell. The weak interlayer exchange coupling between square-planar 2D IrO_{2} layers is readily modified upon compression, with a crossover between magnetic structures around 7 GPa mimicking the effect of an applied magnetic field at ambient pressure. Higher pressures drive an order-disorder magnetic phase transition with no magnetic order detected above 17-20 GPa. The persistence of strong exchange interactions between J_{eff}=1/2 magnetic moments within the insulating IrO_{2} layers up to at least 35 GPa points to a highly frustrated magnetic state in compressed Sr_{2}IrO_{4}, opening the door for realization of novel quantum paramagnetic phases driven by extended 5d orbitals with entangled spin and orbital degrees of freedom.

Abstract
Fermentation is a traditional processing method that can impact the abundance of relevant components in Chinese herbal medicines. Huafeng Dan Yaomu was processed by fermentation. In this study, we investigated changes in toxic alkaloids using high-performance liquid chromatography and analysed the changes in microbial communities during fermentation of Huafeng Dan Yaomu by Illumina MiSeq platform. The results indicated that highly toxic alkaloid compounds including aconitine, mesaconitine and hypaconitine were decreased, whereas benzoylmesaconine and benzoylhypaconitine were increased during fermentation. The dominant bacterial genera in the raw material (day 0) were Bacillus (58·38%), Enterobacter (16·05%), Enterococcus (4·10%) and others (11·48%). After 7 days of fermentation, Pediococcus predominated, increasing from 98·26 to 99·97%. The dominant fungal genera in the raw material (day 0) were Incertae_Sedis_incertae_sedis (45·36%), Eurotiales_unclassified (20·63%), Millerozyma (15·58%) and Saccharomycopsis (10·64%). After 7 days of fermentation, Saccharomycopsis was increased to 90·84%. After 14 days of fermentation, Pichia became the main fungal genera in the fermentation process. There were 16 bacterial genera and seven fungal genera that displayed significant correlation with toxic alkaloids. The dynamics of the microbiota and chemical compounds during fermentation of Huafeng Dan Yaomu were revealed, providing a foundation for further investigation of the effects of microbes on chemical compounds and insights into the manufacturing of Huafeng Dan Yaomu. SIGNIFICANCE AND IMPACT OF THE STUDY: Huafeng Dan Yaomu is a unique fermentation-based micro-organism product. This study reveals that the change in toxic alkaloids during fermentation was related to micro-organisms. The results of this study can be used to improve the Chinese herb medicine fermentation process, such as the selection of beneficial strains and their composition for modern fermentation. The results of this study may also provide new ideas for the processing of Traditional Chinese Medicine.
