Abstract
Osteoarthritis (OA) is a degenerative joint disease characterized by progressive erosion of the articular cartilage and inflammation. Mesenchymal stem cells' (MSCs) transplantation in OA treatment is emerging, but its clinical application is still limited by the low efficiency in oriented differentiation. In our study, to improve the therapeutic efficiencies of MSCs in OA treatment by carbonic anhydrase IX (CA9) siRNA (siCA9)-based inflammation regulation and Kartogenin (KGN)-based chondrogenic differentiation, the combination strategy of MSCs and the nanomedicine codelivering KGN and siCA9 (AHK-CaP/siCA9 NPs) was used. In vitro results demonstrated that these NPs could improve the inflammatory microenvironment through repolarization of M1 macrophages to the M2 phenotype by downregulating the expression levels of CA9 mRNA. Meanwhile, these NPs could also enhance the chondrogenesis of bone marrow-derived mesenchymal stem cells (BMSCs) by upregulating the pro-chondrogenic TGF-β1, ACAN, and Col2α1 mRNA levels. Moreover, in an advanced OA mouse model, compared with BMSCs alone group, the lower synovitis score and OARSI score were found in the group of BMSCs plus AHK-CaP/siCA9 NPs, suggesting that this combination approach could effectively inhibit synovitis and promote cartilage regeneration in OA progression. Therefore, the synchronization of regulating the inflammatory microenvironment through macrophage reprogramming (CA9 gene silencing) and promoting MSCs oriented differentiation through a chondrogenic agent (KGN) may be a potential strategy to maximize the therapeutic efficiency of MSCs for OA treatment.

Abstract
Objective: To analyze the clinical data of a case of lung adenocarcinoma with Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) resistance transforming into sarcoma, and to conduct a literature review to improve the understanding of the resistance mechanism. Histological transformation is a unique form of acquired resistance of EGFR-TKIs in non-small cell lung cancer (NSCLC). Thereinto, the transformation of small cell carcinoma is more common, and the transformation of sarcoma is rarely reported. Methods: Clinicopathological data on the treatment process, pathological features, and clinical outcome of the patient with EGFR-TKIs-resistance lung adenocarcinoma transforming into sarcoma were collected. The literature was reviewed to analyze the pathogenetic mechanism for sarcomatoid carcinoma or sarcoma transformation after drug resistance of adenocarcinoma, as well as the clinical characteristics of the patients and the corresponding therapeutic schemes. Results: We reported a patient with lung adenocarcinoma who developed EGFR-T790M mutation after first-line treatment with icotinib and sarcoma transformation after second-line treatment with almonertinib. Chemotherapy, radioactive particle implantation, antiangiogenic therapy and immunotherapy were followed, but the results were unsatisfactory. There was no report of EGFR-TKIs-resistant lung adenocarcinoma transforming into sarcoma. Among the 14 reports of adenocarcinoma transforming into sarcomatoid carcinoma, 8 cases had EGFR mutation, 3 cases had ALK mutation, 2 cases had ROS1 mutation, and 1 case had no asscoiated sensitive mutation. The median survival of 14 patients with adenocarcinoma transforming to sarcomatoid carcinoma was only 3 months. Conclusions: Sarcoma transformation can be one of the forms of drug resistance in patients with lung adenocarcinoma with EGFR-TKIs. The prognosis of patients with adenocarcinoma after transformation into sarcoma is poor.

Abstract
Objective: To investigate the clinicopathological characteristics of esophageal carcinoma with gland duct differentiation. Methods: The clinical, morphologic and immunohistochemical (IHC) features of eight cases of esophageal carcinoma with gland duct differentiation diagnosed from 2012 to 2022 at the First Affiliated Hospital of Soochow University were summarized. Results: There were four males and four females, with a mean age of 68.5 (range 59-82) years. Two tumors were located in middle esophagus, five in the lower esophagus, and one in the cardia. The mean diameter was 2.4 cm (range 0.6-4.5 cm). The tumor had a bilayer epithelial structure, including the inner luminal epithelium and the outer basal epithelium. Immunohistochemistry showed that CK7 (8/8) and CK18 (8/8) were positive in the inner epithelium. p40 (8/8), p63 (8/8) and CK5/6 (8/8) were positive in the outer epithelium. SMA, calponin and CD117 were all negative. p53 mutants were found in all eight cases (strong and diffuse positivity in 6/8; complete loss of expression in 2/8). No columnar metaplasia, intestinal metaplasia and ectopic gastric mucosa were observed in the surface squamous epithelium in the cases. The mean follow-up time was 21.5 months (range 5-51 months). Seven patients survived and one patient died 31 months after surgery due to recurrence and liver metastasis. Conclusion: Esophageal carcinoma with esophageal gland duct differentiation is a rare tumor with unique histologic and IHC characteristics.

Abstract
Objective: To investigate the effect of chronic endometritis (CE) on the clinical outcomes of patients with failure of first embryo transfer. Methods: A total of 5 605 cycles of frozen-thawed single blastocyst transfer in the reproductive center of the Third Affiliated Hospital of Zhengzhou University from January 2017 to June 2021 were retrospectively collected. After the failure of first embryo transfer, all patients underwent hysteroscopy, and when necessary, endometrial pathology and immunohistochemistry were combined to diagnose CE. Patients were divided into two groups: non-CE group (5 033 cycles) and CE treatment group (572 cycles). The main outcome was live birth rate and the secondary outcomes included clinical pregnancy rate and early abortion rate. The quantitative data were represented by Median (Q1, Q3). The rank sum test was used for comparison between groups. The factors related to live birth rate were analyzed by binary logistic regression model. Results: The incidence of CE was 10.21% (572 cycles) in patients with the failure of first embryo transfer. The maternal age in the non-CE group was 31.0 (29.0, 34.0) years old, and that in the CE treatment group was 31.0 (29.0, 34.0) years old (P<0.001). There was a statistically significant difference in endometrial preparation between the two groups (P=0.010). The endometrial thickness in the CE group was 9.0 (8.2, 10.3) mm on progesterone transformation day, which was higher than that of [9.5 (8.6, 11.0) mm] in the non-CE group (P<0.001). There was no significant difference in clinical pregnancy rate (60.3% (3 035 cycles) vs 63.1% (361 cycles), P=0.193), early abortion rate (17.1% (520 cycles) vs 20.5% (74 cycles), P=0.112) and live birth rate (49.2% (2 477 cycles) vs 49.3% (282 cycles), P=0.969) between the non-CE group and the CE treatment group. The maternal age, endometrial thickness on progesterone transformation day and blastocyst grade were related factors of the live birth rate, and the OR(95%CI) were 0.94 (0.93-0.96), 1.10 (1.06-1.14) and 2.07 (1.84-2.32)), respectively (all P<0.001). Compared with the non-CE group, the CE treatment group did not affect the live birth rate after transplantation, the aOR (95%CI) was 0.99 (0.82-1.18), P=0.882. Conclusions: For patients who underwent the failure of first embryo transfer, hysteroscopy is recommended before single frozen blastocyst transfer, and if necessary, combined with immunohistochemical screening for CE. After standardized treatment, CE patients could obtain similar clinical pregnancy rate, early miscarriage rate and live birth rate as non-CE patients.

Abstract
BACKGROUND Tibiofibular syndesmosis (TFS) widening sometimes is not evident on radiography but can be found under arthroscopy in chronic lateral ankle instability (CLAI). This study aimed to evaluate the effect of TFS widening severity on clinical outcomes and return to activities after isolated Broström operation in CLAI patients and to propose an indication for its surgical intervention. METHODS A total of 118 CLAI patients undergoing diagnostic ankle arthroscopy and open Broström-Gould operation were included. Based on the middle width of TFS measured under arthroscopy, patients were divided into the TFS-2 group (≤2 mm, n = 44), the TFS-3 group (2-4 mm, n = 42), and the TFS-4 group (≥4 mm, n = 32). The time to return to recreational sport and work, Tegner activity score, and proportion of returning to preinjury sports at the final follow-up were evaluated and compared. Other subjective evaluations included the American Orthopaedic Foot & Ankle Society score, visual analog scale, and Karlsson-Peterson score. RESULTS Among the 3 groups, the TFS-4 group demonstrated the longest mean time to return to work and recreational sports, with the lowest proportion returning to preinjury sports. The TFS-4 group showed a significantly higher rate of sprain recurrence (12.5%) than the other 2 groups (P =.021). All the other subjective scores significantly improved after the operation without differences among the 3 groups. CONCLUSION Concomitant severe syndesmotic widening adversely affects the return to activities after Broström operation in CLAI cases. The CLAI patients with a middle TFS width ≥4 mm were associated with delayed return to work and sports, a lower proportion of returning to preinjury sports, and more sprain recurrence, which might require further surgical intervention for syndesmosis in addition to Broström surgery. LEVEL OF EVIDENCE Level III, retrospective cohort study.

Abstract
The meniscus is a fibrocartilaginous tissue of the knee joint that plays an important role in load transmission, shock absorption, joint stability maintenance, and contact stress reduction. Mild meniscal injuries can be treated with simple sutures, whereas severe injuries inevitably require meniscectomy. Meniscectomy destroys the mechanical microenvironment of the knee joint, leading to cartilage degeneration and osteoarthritis. Tissue engineering techniques, as a strategy with diverse sources and customizable and adjustable mechanical and biological properties, have emerged as promising approaches for the treatment of meniscal injuries and are represented by 3D printing. Notably, the heterogeneity of the meniscus, including its anatomical structure, cell phenotype, extracellular matrix, and biomechanical properties, is crucial for its normal function. Therefore, the construction of heterogeneous tissue-engineered menisci (TEM) has become a research hotspot in this field. In this review, we systematically summarize the heterogeneity of menisci and 3D-printed strategies for tissue-engineered anisotropic menisci. The manufacturing techniques, biomaterial combinations, surface functionalization, growth factors, and bioreactors related to 3D-printed strategies are introduced and a promising direction for the future research is proposed.

Abstract
PURPOSE To compare the return-to-activity and long-term clinical outcomes between anatomic lateral ligament reconstruction using the autologous gracilis tendon and modified Broström-Gould (MBG) procedure in chronic lateral ankle instability (CLAI). It was hypothesised that there was no difference between the two techniques. METHODS From 2013 to 2018, 30 CLAI patients with grade III joint instability confirmed by anterior drawer test underwent anatomic reconstruction of lateral ankle ligament with the autologous gracilis tendon (reconstruction group) in our institute. Another 30 patients undergoing MBG procedure (MBG group) were matched in a 1:1 ratio based on demographic parameters. The post-operative American Orthopaedic Foot and Ankle Society (AOFAS) score, visual analogue scale (VAS) pain score, Tegner activity score, Karlsson-Peterson score, surgical complications, return-to-activities and work were retrospectively evaluated and compared between the two groups. RESULTS All subjective scores significantly improved after the operation (all with p < 0.001) without difference between the two groups (all n.s.). The MBG group showed a significantly higher proportion of postoperative sprain recurrence than the reconstruction group (26.7% vs. 0, p = 0.002). The reconstruction group showed a significantly longer period to start walking with full weight-bearing (10.5 ± 6.9 vs. 7.0 ± 3.1 weeks, p = 0.015), jogging (17.1 ± 8.9 vs. 12.7 ± 6.9 weeks, p = 0.043) and return-to-work (13.5 ± 12.6 vs. 8.0 ± 4.7 weeks, p = 0.039) than the MBG group. CONCLUSIONS Both anatomic reconstruction using the autologous gracilis tendon and MBG procedure could equally achieved reliable long-term clinical outcomes and the tendon reconstruction showed a relatively lower incidence of postoperative sprain recurrence but delayed recovery to walking, jogging and return-to-work. The MBG procedure was still the first choice with rapid recovery but the tendon reconstruction was recommended for patients with higher strength demand. LEVEL OF EVIDENCE III.

Abstract
Objective: To investigate the effect of human chorionic gonadotropin (HCG)day serum progesterone (P) level on the live birth rate (LBR) of fresh embryo transfer with GnRH antagonist protocols. Methods: Patients who underwent the first IVF/ICSI in the Reproductive Center of the Third Affiliated Hospital of Zhengzhou University from January 2018 to December 2020 were included for analysis. The patients with normal ovarian response with GnRH antagonist protocols were included (n=765). The receiver operating characteristic curve (ROC) was used to select the optimal cut-off value of serum P on HCG day (0.83 μg/L), and the included cycles were divided into two groups: P<0.83 μg/L (n=444) and P≥0.83 μg/L (n=321). The primary outcome measure was LBR. Secondary outcome measures included clinical pregnancy rate (CPR) and early miscarriage rate. The difference of the above indexes between the two groups was compared. Multivariate logistic regression model was used to analyze the effect of serum P level on LBR in fresh embryo transfer cycles. Results: The maternal ages in P<0.83 μg/L group and P≥0.83 μg/L group were (32.40±5.49) years and (32.53±5.51) yeas, respectively. The paternal ages were (33.35±6.34) years and (33.43±6.38) years, respectively of which, the difference was not statistically significant (P>0.05). The CPR in the P<0.83 μg/L group was 45.9% (n=204), which was significantly higher than that in the P≥0.83 μg/L group (37.1%) (n=119) (P=0.014). There was no significant difference in the early miscarriage rate between the two groups [14.2% (n=29) vs 14.3% (n=17), P=0.986]. The LBR in the P<0.83 μg/L group was significantly higher than that in the P≥0.83 μg/L group [36.3% (n=161) vs 28.0% (n=90), P=0.017]. By multivariate logistic regression model analysis, the maternal age, type of embryo transferred, number of embryos transferred, endometrial thickness on HCG day and serum P level on HCG day were independent risk factors of LBR. The adjust OR(95%CI) were 0.91(0.88-0.94), 2.36(1.04-5.35), 1.84(1.14-2.95), 1.16(1.07-1.25)and 0.63(0.44-0.89), all P<0.05. Conclusion: When the GnRH antagonist protocol is applied in the normal ovarian response population, as the serum P on the HCG trigger day≥0.83 μg/L, the CPR and LBR of fresh embryo transfer are decreased.

Abstract
PurposeThis study aims to evaluate the mid- to long-term outcome of concurrent arthroscopic treatment of osteochondral lesion (OCL) and open anatomical repair of lateral ankle ligaments for severe acute ankle sprain patients and compare them to the outcome of those without OCL.MethodsA total of 166 patients with grade III acute lateral ankle ligament injuries underwent concurrent ankle arthroscopy and open anatomic ligament repair. Forty-three patients (group A) with OCL underwent arthroscopic treatment followed by open ligament repair. A total of 105 patients (group B) without OCL were followed up as the control. The evaluation parameters included sports recovery, postoperative visual analog scale (VAS) pain score, American Orthopaedic Foot and Ankle Society (AOFAS) score, Tegner score, sprain recurrence, satisfaction, and range of motion. Patients in group A were then subgroup-analyzed according to age, sex, body mass index, injury side, OCL location, and stage (Ferkel and Cheng’s staging system).ResultsThe postoperative exercise level of the two groups recovered to more than 90% of the normal level (91.2% ± 11.2% in group A and 90.9% ± 13.3% in group B, n.s.). The average time of group A and group B to return to preinjury sports activity was respectively 4.4 ± 1.0 months and 4.4 ± 1.2 months with no significant difference (p = 0.716). No significant differences were found in the preoperation VAS pain score, AOFAS score, and Tegner score between the two groups. The postoperative VAS pain score in group A was significantly higher than that in group B (0.8 ± 1.7 vs. 0.3 ± 0.8, p = 0.027), but the difference was not clinically important. The postoperative VAS pain score of patients with stage D–F lesions was significantly higher than that of patients with stage B–C lesions (1.3 ± 2.1 vs. 0.3 ± 0.9, p = 0.038).ConclusionsFor the severe acute ankle sprain combined with OCL, the simultaneous arthroscopic treatment and open lateral ankle ligament repair achieved good mid- to long-term outcomes. Except that the pain was more pronounced than in the control group, there were no differences in other outcomes. Postoperative pain was positively correlated with the grade of OCL.

Abstract
Little has been known about the role of long non-coding RNA (lncRNA) involves in change of aged meniscus. Microarray analyses were performed to identify lncRNAs and mRNAs expression profiles of meniscus in young and aging adults and apple bioinformatics methods to analyse their potential roles. The differentially expressed (DE) lncRNAs and mRNAs were confirmed by qRT-PCR. A total of 1608 DE lncRNAs and 1809 DE mRNAs were identified. Functional and pathway enrichment analyses of all DE mRNAs showed that DE mRNAs were mainly involved in the TGF-beta, Wnt, Hippo, PI3K-Akt signaling pathway. The expressions of TNFRSF11B and BMP2 were significantly upregulated in aging group. LASSO logistic regression analysis of the DE lncRNAs revealed four lncRNAs (AC124312.5, HCG11, POC1B-AS1, and AP001011.1) that were associated with meniscus degradation. CNC analysis demonstrated that AP001011 inhibited the expression of TNFRSF11B and AC1243125 upregulated the expression of TNFRSF11B. CeRNA analysis suggested that POC1B-AS1 regulates the expression of BMP2 by sponging miR 130a-3p, miR136-5p, miR 18a-3p, and miR 608. Furthermore, subcellular localization and m6A modification sites prediction analysis of these four lncRNAs was performed. These data lay a foundation for extensive studies on the role of lncRNAs in change of aged meniscus.

Abstract
Cartilage injury of the knee joint is very common. Due to the limited self-healing ability of articular cartilage, osteoarthritis is very likely to occur if left untreated. Bone marrow mesenchymal stem cells (BMMSCs) are widely used in the study of cartilage injury due to their low immunity and good amplification ability, but they still have disadvantages, such as heterogeneous undifferentiated cells. MicroRNAs can regulate the chondrogenic differentiation ability of MSCs by inhibiting or promoting mRNA translation and degradation. In this research, we primarily investigated the effect of microRNA-210-3p (miR-210-3p) on chondrogenic and adipogenic differentiation of BMMSCs in vitro. Our results demonstrate that miR-210-3p promoted chondrogenic differentiation and inhibited adipogenic differentiation of rat BMMSCs, which was related to the HIF-3α signalling pathway. Additionally, miR-210-3p promotes mRNA and protein levels of the chondrogenic expression genes COLII and SOX9 and inhibits mRNA and protein levels of the adipogenic expression genes PPARγ and LPL. Thus, miR-210-3p combined with BMMSCs is a candidate for future clinical applications in cartilage regeneration and could represent a promising new therapeutic target for OA.

Abstract
Objective: To determine the effects of QO-58 on pain behavior associated with monosodium iodoacetate (MIA)-induced OA. Methods: The OA model was established with an intra-articular injection of 3 mg/50 MIA through the right patellar ligament. Then the model rats were treated with 50 mg/kg QO-58 by intraperitoneal injection, and pain-related behaviors were assessed by single administration and multiple administrations of QO-58. Results: Single adminstration of QO-58 increased the mechanical threshold and prolonged the withdrawal latency of OA pain with the antinociceptive effect occurring at 6 h and 10 h. Compound QO-58 was administered intraperitoneally once a day from day 10 to 14. QO-58 significantly increased the mechanical threshold and prolonged the withdrawal latency of OA rats at 12 and 14 days. Conclusion: QO-58 showed antinociceptive effects for OA pain in the MIA model after pain development. QO-58 may be an alternative therapeutic treatment for OA.
