Abstract
OBJECTIVES The abutments produced with circular symmetry failed to accurately replicate the natural teeth's cervical shapes. The purpose of this study was to measure cervical cross-sections of maxillary anterior teeth using cone beam computed tomography (CBCT) images to design anatomic healing abutments. MATERIALS AND METHODS CBCT data of 61 patients were analyzed using Ez3D Plus software. Measurements were taken at the cemento-enamel junction (CEJ) and 1 mm coronal to CEJ for maxillary central incisors, lateral incisors, and canines. Various parameters, including area, perimeter, and eight line segments in the distal (a), disto-palatal (b), palatal (c), mesio-palatal (d), mesial (e), mesio-labial (f), labial (g), and disto-labial (h) directions, were used to describe dental neck contours. The ratios (f/b and h/d) were analyzed, and differences based on sex and dental arch morphology were explored. RESULTS Significant differences were found in area and perimeter between males and females, but not in f/b and h/d ratios. Differences in the f/b ratio were observed among dental arch morphologies for maxillary central incisors, lateral incisors, and canines. CONCLUSIONS CBCT measurements of cervical cross-sections provide more accurate data for designing anatomic healing abutments. The fabrication of anatomical healing abutments needs to consider the influence of gender on cervical size and to explore the potential effect of arch shape on cervical morphology. CLINICAL SIGNIFICANCE The novel method provides detailed measurements for the description of dental cervical contours for patients with bilateral homonymous teeth missing. The measurements of this study could be utilized to design more accurate anatomic healing abutments to create desired morphology of peri-implant soft tissue.

Abstract
Currently, the classification of bone mineral density (BMD) in many research studies remains rather broad, often neglecting localized changes in BMD. This study aims to explore the correlation between peri-implant BMD and primary implant stability using a new artificial intelligence (AI)-based BMD grading system. 49 patients who received dental implant treatment at the Affiliated Hospital of Stomatology of Fujian Medical University were included. Recorded the implant stability quotient (ISQ) after implantation and the insertion torque value (ITV). A new AI-based BMD grading system was used to obtain the distribution of BMD in implant site, and the bone mineral density coefficients (BMDC) of the coronal, middle, apical, and total of the 1 mm site outside the implant were calculated by model overlap and image overlap technology. Our objective was to investigate the relationship between primary implant stability and BMDC values obtained from the new AI-based BMD grading system. There was a significant positive correlation between BMDC and ISQ value in the coronal, middle, and total of the implant (P < 0.05). However, there was no significant correlation between BMDC and ISQ values in the apical (P > 0.05). Furthermore, BMDC was notably higher at implant sites with greater ITV (P < 0.05). BMDC calculated from the new AI-based BMD grading system could more accurately present the BMD distribution in the intended implant site, thereby providing a dependable benchmark for predicting primary implant stability.

Abstract
Chitin, the second most abundant polysaccharide on earth, possesses unique characteristics, including biosafety, biodegradability, and procoagulant activity, making it an attractive material for hemostasis. However, the conventional bottom-up construction of chitin-based materials is intricate and time-consuming. In this study, we have developed a top-down strategy to prepare a 3D porous chitin-based hemostatic sponge with exceptional hemostatic properties and antibacterial activity, directly from the spongy Pleurotus eryngii. The top-down method involves deproteinization, in situ quaternization, and tannin acid crosslinking. The obtained sponge has an interconnected microporous structure with high porosity (89.7 ± 3.2 %), endowing it with high water absorption (2047 ± 105 %) and rapid water-triggered shape-memory behavior (< 2 s). The sponge exhibits superior blood coagulant activity and outperforms standard medical gauze, gelatin sponge, and chitosan sponge in both topical artery and non-compressive liver puncture wound. In addition, the sponge exhibited significant antibacterial activity against both gram-positive Staphylococcus aureus and gram-negative Escherichia coli. In summary, this study provides a straightforward and practical approach for constructing an antibacterial and hemostatic chitin sponge that could be a valuable option for treating bleeding wounds.

Abstract
BNTA is known to have a therapeutic effect on knee osteoarthritis and inflammatory osteoclastogenesis. However, the protective effect of BNTA regarding temporomandibular mandibular joint osteoarthritis (TMJOA) and its underlying mechanism and physiological target remains unclear. In the present study, BNTA ameliorated cartilage degradation and inflammation responses in monosodium iodoacetate (MIA)-induced TMJOA in vivo. In IL-1β-induced condylar chondrocytes, BNTA prevents oxidative stress, inflammatory responses and increasing synthesis of cartilage extracellular matrix through activating nuclear factor-E2-related factor 2 (NRF2) signaling. Suppression of NRF2 signaling abolishes the protective effect of BNTA in TMJOA. Notably, BNTA may bind directly to ALDH3A1 and act as a stabilizer, as evidenced by drug affinity responsive target stability assay (DARTS), cellular thermal shift assay (CETSA) and molecular docking results. Further investigation of the underlying molecular and cellular mechanism infers a positive correlation of ALDH3A1 regulating NRF2 signaling. In conclusion, BNTA may attenuate TMJOA progression via the ALDH3A1/NRF2 axis, inferring that BNTA is a therapeutic target for treating temporomandibular mandibular joint osteoarthritis.

Abstract
The carbon fiber reinforced polyetheretherketone (CFR-PEEK) has been increasingly used in orthopedics dentistry due to its excellent biocompatibility and mechanical properties. However, the biological inertness and poor antibacterial activity limit its clinical applications. This paper focused on the performances of CFR-PEEK with porous morphology that were exposed to different sulfonation periods (1, 3, 5, and 10 min, corresponding to CP-S1, CP-S3, CP-S5, and CP-S10, respectively). Residual sulfuric acid was removed by acetone rinsing, NaOH immersion, and hydrothermal treatment before in vitro and in vivo studies. The results showed some significant difference in the physicochemical properties, including energy dispersive X-ray spectroscopy (EDS) map of sulfur atoms, X-ray photoelectron spectroscopy (XPS) of valences of sulfur ions, Fourier transformation infrared spectroscopy (FTIR), hydrophilicity, hardness, and elastic modulus among CP-S3, CP-S5, and CP-S10. However, CP-S5 and CP-S10 were more effective in promoting the proliferation, adhesion, and osteogenic differentiation of seeded bone mesenchymal stem cells (BMSCs) and growth inhibition of S. aureus and P. gingivalis compared with other groups. Furthermore, the CP-S5 and CP-S10 samples achieved better cranial bone repair than the non-sulfonation group in a rat model. Therefore, it can be inferred that both 5 and 10 min are viable sulfonation durations for 30% CFR-PEEK. These findings provide a theoretical basis for developing CFR-PEEK for clinical applications.

Abstract
OBJECTIVES Bone marrow-derived mesenchymal stem cells (BMSCs) - based tissue engineering is an important strategy for treatment of bone defects. However, the ischemia environment limits the survival and biological functions of BMSCs. The present study aimed to investigate the effect of leukemia inhibitory factor (LIF) on the apoptosis of BMSCs induced by hypoxia and serum-deprivation (H&SD) as well as the underlying pathway mechanism. METHODS Mitochondrial membrane potential (MMP) was determined by flow cytometry. The apoptotic phenomenon of nuclear morphology was detected by fluorescence microscope. The ratio of apoptotic BMSCs was investigated by Annexin V/propidium iodide (PI) double staining and flow cytometric analysis. The expression of apoptosis-related molecules was detected by quantitative polymerase chain reaction (qPCR) and western blotting. RESULTS H&SD treatment induced a series of apoptotic phenotypes, including the downregulation of MMP, the apoptotic phenomenon of nuclear morphology, the increased rate of BMSCs at early and late apoptotic stage, and the reduced B-cell lymphoma-2 (Bcl-2)/Bcl-2-associated X (Bax) ratio. Administration of recombinant LIF alleviated the apoptosis of BMSCs induced by H&SD, which was reflected in recovery of MMP, morphology of nuclei, rate of apoptotic cells and inhibition of cleaved Caspase-3. The results of western blot demonstrated that phosphorylation of janus kinase (JAK) 1 and signal transducer and activator of transcription (STAT) 3 was inhibited by H&SD treatment, which was upregulated by LIF administration. JAK1-specific inhibitor GLPG0634 or STAT3-specific inhibitor S3I-201 eliminated the protective effects of LIF on the apoptosis of BMSCs. CONCLUSION These data indicated that LIF played a protective role in apoptosis of BMSCs induced by ischemia via activating JAK1/STAT3 signaling pathway.

Abstract
BackgroundThe conventional scoring methods of radiographic joint space narrowing (JSN) in rheumatoid arthritis (RA) such as the Genant-modified Sharp score (GSS) are widely accepted but include subjective and time-consuming nature1. Therefore, we have developed an in-house software equipped with partial image phase-only correlation (PIPOC)2 which can automatically quantify joint space width (JSW) change.ObjectivesThe purpose of this study was to investigate whether the in-house software can predict the inhibitory effect of tocilizumab on joint destruction in a short period of time.MethodsThe study included 39 RA patients (35 female) who were treated with tocilizumab (Table 1). Radiological progression of the metacarpophalangeal and the proximal interphalangeal joints was evaluated according to the GSS at 0, 6, and 12 months. Automatic measurement was performed by the in-house software (Figure 1). We then validated in-house software in terms of accuracy in detecting the JSN.Figure 1.The algorithm flow of in-house software equipped with PIPOCTable 1.Clinical characteristics of RA patientsvariablebaseline6 months12 monthsTotal number of patients39Sex, female/male35/4Rheumatoid factor status, positive/negative29/10Age, mean (SD) years61.5 (14.6)Duration of disease, mean (SD) months111.4 (85.0)Swollen joint count, mean (SD)6.0 (4.7)3.5 (3.5)2.9 (4.0)Tender joint count, mean (SD)6.4 (3.5)2.9 (2.2)1.9 (2.0)DAS28-ESR, mean (SD)4.9 (1.2)3.0 (1.1)2.6 (1.0)DAS28-CRP, mean (SD)4.4 (1.1)3.0 (0.9)2.6 (0.8)RA, rheumatoid arthritis; SD, standard deviation; DAS28, disease activity score with 28 joints; ESR, erythrocyte sedimentation rate; CRP, C-reactive proteinResultsTo ensure homogeneity of the subjects, we targeted the joints with GSS = 0 at baseline in the software analysis. The success rate of the in-house software for JSW measurement was 96.8% (449/464). Here, the GSS (+)/PIPOC (+) were defined as joints with JSN progression according to the GSS and the software analysis, respectively. Otherwise, joints were defined as the GSS (-)/PIPOC (-) namely non-progressive JSN. The 0–12-month GSS with the 0–6-month GSS (+) group was significantly more JSN progression than the 0–6-month GSS (-) group (Mann-Whitney U test, p < 0.001). Similarly, the 0–12-month PIPOC with the 0–6-month PIPOC (+) group was significantly more JSN progression than the 0–6-month PIPOC (-) group (p < 0.001). The 0–12-month JSW change of finger joints with the 0–12-month GSS (+) detected by the in-house software was significantly greater than the 0–12-month GSS (-) (p = 0.02).ConclusionOur in-house software equipped with PIPOC might be able to predict the subsequent joint destruction with 6 months observations.References[1]Genant HK, et al: Assessment of rheumatoid arthritis using a modified scoring method on digitized and original radiographs.

Abstract
BACKGROUND Accumulating evidence shows that pleomorphic adenoma (PA) exhibits a unique capsular invasion and with a crucial role in recurrence. This study was designed to explore RNA expression profiles in salivary gland PA in an attempt to further analyse genes associate with capsule invasion. METHODS We evaluated the expression profiles of 4 salivary gland PA patients by RNA-sequencing. The principal functions of the differentially expressed mRNAs (DEGs) were explored using GO and KEGG analysis. Then, RT-qPCR and correlation analyses were performed to verify the candidate DEGs in 59 PA patients, and immunohistochemical examinations were conducted to validate candidate DEGs. Finally, the COMP-related genes were screened using correlation and biological pathway enrichment analysis, and further validated by RT-qPCR. RESULTS A total of 974 DEGs were significantly upregulated and 1464 were downregulated (fold change ≥2.0; p < 0.05). Based on GO and KEGG analyses, extracellular matrix organization and the PI3K-Akt signaling pathway might play pivotal roles in the tumorigenesis of PA. 40 DEGs were screened and validated by RT-qPCR, 11 upregulated and 5 downregulated DEGs were consistent with the sequencing results. Cartilage oligomeric matrix protein (COMP) was identified to have a significant correlation with the capsular invasion of PA and expression of COMP in patients with invasive capsular PA was significantly stronger than PA. Finally, further results could reveal that 5 highest-scoring genes were screened as hub genes for COMP. CONCLUSIONS These findings suggested that COMP may be a prognostic target for PA and might contribute to its capsular invasion.

Abstract
Objective: To compare the clinical effects of single-incision robot-assisted laparoscopic radical prostatectomy (RARP) with and without extraperitoneal special channel device. Methods: The clinical data of 70 patients who had undergone RARP in the Robotic Minimally Invasive Surgery Center of Sichuan Provincial People's Hospital from September 2020 to February 2021 were analyzed retrospectively, including 29 cases who were operated on without special channel device (group A) and 41 cases with special channel device (group B). All operations were performed by robot-assisted single-incision retrograde bladder neck exfoliation via extraperitoneal approach in patients by the same operator. The operation time, intraoperative blood loss, the bladder neck urethral anastomosis time, postoperative hospital stay, postoperative exhaust time, positive rate of incisal margin, indwelling time of urinary catheter, retention rate of postoperative erectile function, satisfaction rate of immediate postoperative urine control, positive rate of postoperative lymph node pathology, incision length, treatment cost and the rate of prostate specific antigen (PSA)lower than 0.2 μg/L at 6 weeks after operation were compared between the two groups. Results: All 70 cases were operated successfully. The difference of age[ (68.9±3.9) vs (69.4±5.4) years], preoperative PSA level[14.1(6.3, 19.8)vs13.7(5.8, 18.1)μg/L], prostate volume[44.8(30.7,172.6)vs 56.3(40.9,163.4)ml ] of the two groups was not statistically significant(all P>0.05). The difference of operation time [ (59.1±18.5) vs (59.6±18.0) min ], intraoperative blood loss [93(66,198)vs 95(68,203) ml ], bladder neck urethral anastomosis time [ (12.6±1.3) vs (13.7±2.8) min ], postoperative hospital stay [ (8.1±2.3) vs (9.1±1.3) d], postoperative exhaust time [ (1.4±0.6) vs (1.3±0.6) d], positive rate of incisal margin (20.7% vs 19.5%), indwelling time of the urinary catheter after operation [ (6.8±1.5) vs (7.1±2.0) d ], the retention rate of postoperative erectile function (31.0% vs 27.0%), the satisfaction rate of immediate postoperative urine control (79.3% vs 75.6%), the positive rate of postoperative lymph node pathology (17.2% vs 14.6%), the length of incision [ (5.1±0.5) vs (6.1±0.4) cm ], the rate of PSA lower than 0.2 μg/L at 6 weeks after operation (86.2% vs 83.0%) of the two groups was not statistically significant(all P>0.05). The operation cost of group A[(62 000±4 000) yuan]was lower than group B[(68 000±4 000) yuan] (P<0.05). Conclusion: Extraperitoneal non-special channel device single-incision RARP is safe and feasible.

Abstract
The selection of the superficial or deep drainage system for use with the radial forearm free flap (RFFF) remains controversial. The aim of this study was to identify the optimal drainage system for single venous anastomosis. A systematic review and cumulative meta-analysis was performed to assess superficial and deep system single venous anastomosis for use with the RFFF in postoperative reconstruction of the head and neck. This study included 1073 flaps (495 superficial system-based flaps, 578 deep system-based flaps) reported in six studies. The outcomes assessed in the studies selected for this meta-analysis included venous compromise, flap failure, and the salvage success rate. Venous compromise was more common in the superficial system group (odds ratio (OR) 2.29, 95% confidence interval (CI) 1.36-3.86, P=0.002). The rate of successful salvage was higher with the superficial system (OR 8.19, 95% CI 1.75-38.3, P=0.008). The rate of flap failure was lower in the superficial system group (OR 0.30, 95% CI 0.04-2.48, P=0.27). Although the deep system showed a lower risk of venous compromise, the evidence provided by the meta-analysis was insufficient to determine which type of drainage system is more suitable for single venous anastomosis in RFFF. All included studies were cohort studies; therefore, findings must be interpreted with caution.

Abstract
PURPOSE Despite the large number of osteoporosis patients in China, the diagnosis and treatment rates remain low. The Fracture Risk Assessment Tool (FRAX) can be used to effectively evaluate fracture risk. In this study, we explored the Chinese-specific thresholds of FRAX without the T-score. METHODS In all, 264 postmenopausal women aged > 50 years were randomly recruited from community-medical centers. All subjects completed self-reported questionnaires, BMD measurements, and spinal radiographs. The 10-year hip and major osteoporotic fracture risks were calculated by FRAX. A new threshold for both 10-year hip and major osteoporotic fracture risk was explored with receiver operating characteristic (ROC) curve analysis. RESULTS Overall, 92 subjects were diagnosed with osteoporosis. Among them, 14 participants with T-score > - 2.5 were diagnosed with osteoporosis based on clinical fractures. ROC analysis showed the cut-off value of the 10-year hip osteoporotic fracture for detecting osteoporosis was 0.95%, while that of 10-year major osteoporotic fracture was 4.95%. The sensitivity and specificity of the 10-year hip osteoporotic fracture probability for detecting osteoporosis were 0.86 and 0.59, respectively, while the guideline-recommended threshold had a sensitivity of 0.49 and specificity of 0.83. The sensitivity and specificity of the 10-year major osteoporotic fractures with the new threshold were 0.76 and 0.69, respectively, while the recommended threshold had a sensitivity of 0 and specificity of 1. CONCLUSION Current guideline-recommended FRAX thresholds without BMD showed low sensitivity. Therefore, 10-year osteoporotic hip fracture probability ≥ 0.95% and 10-year osteoporotic major fracture probability ≥ 4.95% are recommended as the new thresholds.

Abstract
While there have been previous studies examining the relation between the rs17820943 and rs6072081 polymorphisms in the v-maf musculoaponeurotic fibrosarcoma oncogene homolog B (MAFB) gene and rates of nonsyndromic cleft lip with or without cleft palate (NSCL/P), at present the results of these studies have been inconsistent. This meta-analysis therefore aimed to conduct a more robust assessment of the association between the MAFB rs17820943 and rs6072081 polymorphisms and NSCL/P risk. The Embase, Web of Science, PubMed, the China National Knowledge Internet (CNKI), and Wanfang databases were systematically searched to identify relevant studies. In total, five studies incorporating 2769 patients and 2885 controls were identified assessing the rs17820943 polymorphism and three studies incorporating 1242 patients and 1310 controls assessing the rs6072081 polymorphism were identified. This analysis revealed the MAFB rs17820943 and rs6072081 polymorphisms to be linked to a significantly reduced NSCL/P risk (rs17820943: C vs T: OR=0.76, 95% CI=0.70-0.82; CC vs CT: OR=0.75, 95% CI=0.67-0.85; CC vs TT: OR=0.58, 95% CI=0.49-0.67; CC+CT vs TT: OR=0.67, 95% CI=0.59-0.77; CT+TT vs CC: OR=1.43, 95% CI=1.28-1.60; rs6072081: A vs G: OR=0.77, 95%CI=0.68-0.86; AA vs AG: OR=0.76, 95%CI=0.64-0.90; AA vs GG: OR=0.58, 95%CI=0.45-0.74; AA+AG vs GG: OR=0.68, 95%CI=0.54-0.84; AG+GG vs AA: OR=1.40, 95% CI=1.19-1.65). The results of the present meta-analysis indicate that in an East Asian population, for both rs17820943 and rs6072081 were associated with NSCL/P.

Abstract
Objective: To examine the feasibility of small drain in transoral endoscopic thyroidectomy vestibular approach (TOETVA). Methods: A prospective research was performed in Department of Oncology Plastic Surgery/Head and Neck Surgery, Hunan Cancer Hospital, from October 2018 to March 2019. Totally 103 patients who met the inclusion and exclusion criteria, signed the operation agreement of TOETVA, had their surgery completed and followed-up over 6 months, were enrolled in analysis. A central venous catheter was used as a drain tube in all cases (outer diameter 1.7 mm, inner diameter 1.0 mm). Visual analogue scale (VAS) was applied for assessing pain scores during the first 24 hours after the operation. Vancouver scar scale (VSS) was used for assessing the scar left by the drainage. The drainage volume (minimum scale:10 ml, approximate read: 1 ml) was recorded every 2 hours during the first postoperative 12 hours, every 4 hours during 12 to 24 hours, every 8 hours during 24 to 48 hours, and once from 48 hours until extubation. The volume of drainage, the cumulative volume and the percentage of cumulative volume accounting for the total volume were calculated. The data of residual volume (subtract the cumulative volume from the total volume) in the postoperative 24, 32 and 40 hours were analyzed, and their upper one-side P(95) was calculated by percentile method. Results: There were 12 males and 91 females. The age was (36.6±9.7) years (range: 18 to 58 years). The intraoperative tube-inserting time was (10.1±2.6) minutes (range: 6 to 18 minutes). The pain score on the first day was 2.7±1.1 (range: 1 to 5). The extubation time was (2.7±0.5) days (range: 2 to 4 days). VSS scores in the postoperative 1(st) month and 6(th) month were 2.9±1.3 (range: 0 to 7) and 0(2)(M(Q(R))), respectively. The size of the scar was 0 (2.5) mm in the postoperative 6(th) month. Sixty-four patients had no visible scars. There were 5 patients who had postoperative drain-related complications (1 for air leakage, 1 for tube blockage, 3 for subcutaneous hydrop, 2 for regional infection), who were all cured after proper treatment. The total volume of drainage for 98 patients without postoperative drain-related complications was (80.1±12.2) ml (range: 58 to 131 ml). The cumulative drainage within 8 hours accounted for (53.8±4.2)% (range: 41.0% to 62.9%) of the total drainage. The volume of residual fluids in the postoperative 32 hours was estimated to (5.8±2.7) ml (range: 0 to 12 ml,P(95)=10.0 ml). Conclusions: The small drain tubecan be applied in TOETVA, providing a satisfied cosmetic appearance and a reliable drainage. The main exudation period of the wound is within 8 hours after the operation. If a residual volume less than 10 ml is considered to be self-absorbable, the shortest safe extubation point for 95% patients without drain-related complications should be 32 hours after the operation.

Abstract
Objective: To explore the effects of pedicled rectus abdominis myocutaneous (PRAM)flap combined with free deep inferior epigastric artery perforator (DIEAP) flap carrying inguinal lymphatic flap in breast reconstruction and upper limb lymphedema treatment post radical mastectomy. Methods: From October 2014 to September 2016, 9 patients with upper limb lymphedema after mastectomy were treated with PRAM flap combined with free DIEAP flap carrying inguinal lymphatic flap for breast reconstruction and upper limb lymphedema treatment in Hunan Province Cancer Hospital. The patients were all females, aged 34-66 (44±7) years. The location of deep inferior epigastric artery perforator was detected by audible Doppler ultrasound blood stream detector and computed tomography angiography for designing combined tissue flap, with length of (25.32±0.27) cm, width of (13.14±0.76) cm, and thickness of (3.55±0.34) cm. The donor site of combined tissue flap was closed by suturing, and two or more tubes for negative pressure drainage were placed according to the situation of donor site and recipient site. Operation time and average placing time of negative pressure drainage tube, postoperative condition of combined tissue flap and the donor site, reconstructed breast condition, recovery of upper limb lymphedema were documented and followed up. Results: The operation time was 290-420 (396±55) min. The average retaining time of negative pressure drainage tube in breast was 5.9 d, while the average retaining time of negative pressure drainage tube in abdomen was 4.3 d. Ecchymoma occurred in DIEAP flap of one patient and in the flap donor site of another patient. Delayed healing was also seen in the rectus abdominis myocutaneous flap of a patient, which healed eventually after dressing change, and the other flaps survived well. The appearance of reconstructed breast was good with good elasticity, and no contracture or deformation occurred in the tissue flap. The upper limb lymphedema in 7 patients was alleviated in varying degrees, with 2.0-4.0 cm reduction in circumference. During follow-up of 12-24 months of 9 patients, averaged 17.5 months, with 6 patients received long term bandage pressure therapy and physical therapy to the affected limbs after operation and all patients were satisfied with appearances of the affected limbs. Neuropathic pain in affected limbs was significantly relieved in 2 patients and stopped aggravating in the other 2 patients. Only linear scar was seen in the donor site of abdomen without affecting obviously the function of abdomen. Conclusions: The PRAM flap combined with free DIEAP flap carrying inguinal lymphatic flap is an effective way for breast reconstruction and upper limb lymphedema treatment post mastectomy.

Abstract
Chinese hamster ovary (CHO) cells are a common tool utilized in bioproduction and directed genome engineering of CHO cells is of great interest to enhance recombinant cell lines. Until recently, this focus has been challenged by a lack of efficacious, high throughput, and low-cost gene editing modalities and screening methods. In this work, we demonstrate an improved method for gene editing in CHO cells using CRISPR RNPs and characterize the endpoints of Cas9 and ZFN mediated genetic engineering. Furthermore, we validate sequence decomposition as a cost effective, rapid, and accurate method for assessing mutants and eliminating non-clonal CHO populations using only capillary sequencing.

Abstract
AIM The aryl hydrocarbon receptor (AhR)-ligand axis has been shown to be involved in inflammatory diseases and bone homeostasis. However, the activation of AhR signalling pathway and the possible functions of AhR ligands in periodontitis are underexplored. This study investigated the expression of the AhR target gene cytochrome P450 subfamily B member 1 (CYP1B1) and the functions and mechanisms of the AhR ligand 6 formylindolo[3,2-b]carbazole (FICZ) in periodontitis. MATERIALS AND METHODS CYP1B1 expression was detected in human periodontitis samples, mice with ligature-induced periodontitis and lipopolysaccharide (LPS)-induced inflammation in periodontal ligament cells (PDLCs) in vitro. FICZ was administered topically or systemically. The therapeutic functions of FICZ were detected via qPCR, micro-computed tomography and immunohistochemistry. Finally, the mechanisms of AhR signalling in periodontitis were investigated by cell assays. RESULTS CYP1B1 expression was downregulated in periodontitis. FICZ rescued the alveolar bone loss and mitigated the inflammatory cytokines in periodontitis mice. In vitro, FICZ pre-treatment reduced the LPS-induced inflammation in PDLCs via the increased phosphorylation of STAT3. Additionally, FICZ prompted the mineralization of PDLCs via activation of the Wnt/β-catenin signalling pathway. CONCLUSION AhR signalling pathway is suppressed in periodontitis and the AhR ligand FICZ can prevent periodontitis.

Abstract
Acylated ghrelin (AG) is a gastrointestinal (GI) peptide mainly secreted by the stomach that promotes cytosolic lipid droplets (CLD) hypertrophy in adipose tissues and liver. However, the role of AG in the regulation of lipid metabolism in the intestine remains unexplored. This study aimed at determining whether AG influences CLD production and chylomicron (CM) secretion in the intestine. The effects of AG and oleic acid on CLD accumulation and CM secretion were first investigated in cultured Caco-2/15 enterocytes. Intestinal lipid metabolism was also studied in Syrian Golden Hamsters submitted to conventional (CD) or Western (WD) diets for 8 weeks and continuously administered with AG or physiological saline for the ultimate 2 weeks. In cultured Caco-2/15 enterocytes, CLD accumulation influenced CM secretion while AG reduced fatty acid uptake. In WD hamsters, continuous AG treatment amplified chylomicron output while reducing postprandial CLD accumulation in the intestine. The present study supports the intimate relationship between CLD accumulation and CM secretion in the intestine and it underlines the importance of further characterizing the mechanisms through which AG exerts its effects on lipid metabolism in the intestine.

Abstract
Previously we have demonstrated that sclerostin inhibits stress-induced odontogenic differentiation of odontoblasts and accelerates senescence of dental pulp cells (DPCs) Odontoblasts and DPCs are main functioning cells for inflammation resistance and tissue regeneration in dentine-pulp complex. Sclerostin is relevant for systemic inflammation and chronic periodontitis processes, but its effects on dental pulp inflammation remains unclear. In this study, we found that sclerostin expression of odontoblasts was elevated in lipopolysaccharide-induced inflammatory environment, and exogenous sclerostin increased the production of pro-inflammatory cytokines in inflamed odontoblasts. Furthermore, sclerostin activated the NF-κB signaling pathway in inflamed odontoblasts and the NF-κB inhibitor reversed the exaggerative effects of sclerostin on the pro-inflammatory cytokines production. Additionally, sclerostin promoted adhesion and migration of inflamed DPCs, while inhibiting odontoblastic differentiation of inflamed DPCs. Sclerostin also might enhance pulpal angiogenesis. Taken together, it can therefore be inferred that sclerostin is upregulated in inflamed odontoblasts under pulpal inflammatory condition to enhance inflammatory responses in dentine-pulp complex and impair reparative dentinogenesis. This indicates that sclerostin inhibition might be a therapeutic target for anti-inflammation and pro-regeneration during dental pulp inflammation.

Abstract
Objective: To investigate the mechanisms of lncRNA on the occurrence and development of NOA by constructing ceRNA regulation network of lncRNA, miRNA and mRNA. Methods: Samples of adult human testis were obtained from NOA patients and OA patients with normal spermatogenesis (controls), recruited from the Reproductive Medicine Center of Nanfang Hospital from June 2017 to June 2018. Differentially expressed lncRNAs and mRNAs in testicular tissues from patients with NOA were identified by microarray analysis in previous association study. In this study, differentially expressed lncRNAs and mRNA were used to construct the ceRNA regulatory network in NOA and clarify the interaction relationship among lncRNA, miRNA and mRNA. GeneMANIA database was used to construct Protein-Protein Interaction (PPI) of the mRNAs in ceRNA regulatory network. WebGestalt toolkit was employed to perform gene function and pathway enrichment analyses of those coding genes. Finally, qRT-PCR and dual luciferase reporter system were employed for further experimental validation. Results: The ceRNA regulatory network of lncRNA, miRNA and mRNA consists of 21 nodes and 26 edges, of which 4 lncRNAs, 13 miRNAs and 4 mRNAs. 19 proteins were found to interact with the mRNA coding proteins in ceRNA regulatory network by PPI analysis. Gene oncology and KEGG pathway enrichment analyses indicate these coding genes were significantly enriched in pentose metabolic process and pentose phosphate pathway. Furthermore, lncRNA ANXA2P3 was found binding with miR-613 and miR-206 to inhibit mRNA TKT expression. Conclusion: lncRNAs exert an important role in the occurrence and development of NOA via ceRNA regulatory network, which could be used as new biomarkers for NOA treatment.

Abstract
OBJECTIVE To evaluate the safety and efficacy of endoscopic submucosal multi-tunnel dissection (ESMTD) for early esophageal cancer lesions larger than 3 cm in diameter or cumulatively greater than 1/2 lumen size. METHOD Early esophageal cancer lesions in 15 patients were detected by endoscopy and endoscopic ultrasonography in our endoscopy center from December 2012 to June 2015. All lesions were successfully resected by ESMTD and diagnosed by pathology, and therapeutic efficiency and safety were followed after surgery. RESULTS All 15 of the early esophageal cancer lesions were resected by ESMTD. The pathological results showed 9 moderately differentiated and 6 highly differentiated squamous cell carcinomas. En bloc resection was achieved in 13 lesions, with negative lateral and basal margins on pathology, whereas the other 2 required additional surgery. The average diameter of the resected lesions was 4.2±0.9 cm. The mean procedure time was 94.7±52.9 min. Esophageal stenosis was observed in 7 patients for whom esophageal water balloon dilatation was performed. No residual or recurrent lesion was found during the 6-36-month follow-up period. CONCLUSION ESMTD is a safe and efficient technique for treating large early esophageal cancer lesions. Grasping the key techniques of this procedure can reduce operating difficulty and shorten the operating time.

High-throughput sequencing analysis of the expression profile of microRNAs and target genes in mechanical force-induced osteoblastic/cementoblastic differentiation of human periodontal ligament cells.

Abstract
Mechanical tension force directs the lineage commitment of periodontal ligament cells (PDLCs) to osteogenesis; however, the underlying mechanisms, especially those at the post-transcriptional level, remain unclear. In the present study, we developed an in vitro force-loading model for PDLCs. Then, high-throughput sequencing was used to identify the expression profile of microRNAs (miRNAs) for stretched PDLCs. The candidate target genes of differentially expressed miRNAs were predicted by bioinformatics analysis. A total of 47 miRNAs were found to be differentially expressed in stretched and non-stretched PDLCs; of these, 31 were upregulated and 16 were downregulated. Further, 9 osteogenesis-related miRNAs (miR-221-3p, miR-138-5p, miR-132-3p, miR-218-5p, miR-133a-3p, miR-145-3p, miR-143-5p, miR-486-3p, and miR-21-3p) were validated by quantitative reverse transcription-polymerase chain reaction (RT-qPCR). Gene Ontology (GO) and Kyoto Encyclopedia of Gene and Genome (KEGG) pathway analysis were then carried out to reveal the potential functions of predicted target genes. Among the top 20 enriched pathways, the Hippo signaling pathway was selected for further functional analysis. Several important components of the Hippo signaling pathway, including YAP1, WWTR1, TEAD2, CTGF, DVL2, GDF5, GLI2, LIMD1, WTIP, LATS1, and TEAD1, were predicted to be target genes of differentially expressed miRNAs and were determined to be upregulated in stretched PDLCs. Among them, YAP1, WWTR1, TEAD2, CTGF, DVL2, and GDF5 were positive regulators of osteogenesis. These findings may provide a reliable reference for future studies to elucidate the biological mechanisms of orthodontic tooth movement (OTM).

Abstract
In this study, we aimed to explore the effects of imatinib on the proliferation of rheumatoid arthritis synovial cell (RA-FLS) and inflammatory responses by regulating CSF1R. Differential genes were screened via microarray analysis, followed by being analysed through the weighted co-expression network (WGCNA) network, that included module and cluster analysis. The relationship between imatinib and genes was visualized using the Search Tool for the Retrieval of Interacting Genes (STITCH) database. Expressions of mRNA and protein were determined by reverse transcription-polymerase chain reaction (RT-PCR) and Western blot, respectively. Cell viability was examined via clone formation assay, while cell cycle and apoptosis were analysed through flow cytometry analysis. The hub gene CSF1R was ultimately determined by microarray analysis and WGCNA analysis. Colony-stimulating-factor receptor-1 (SF1R) was highly expressed in rheumatoid arthritis tissues and cells, and CSF1R over-expression could promote inflammatory responses. Moreover, CSF1R could promote RA-FLS proliferation, inhibit apoptosis and accelerate the cell cycle. The targeting relationship between imatinib and CSF1R was also validated in this study. Imatinib attenuated RA-FLS inflammation in a concentration-dependent manner. Meanwhile, imatinib could inhibit RA-FLS proliferation and promote apoptosis, ultimately reducing the damage of RA-FLS. Over-expression of CSF1R accelerated the cell cycle and proliferation of RA-FLS, while inhibiting cell apoptosis. Conversely, imatinib could significantly restrain the cell cycle and viability of RA-FLS and accelerated apoptosis via suppression of CSF1R expression. Further, histological and serological assay investigated and proved the proinflammatory effects of CSF1R in RA rabbits.

Abstract
Background Senescence-related impairment of proliferation and differentiation limits the use of dental pulp cells for tissue regeneration. Deletion of sclerostin improves the dentinogenesis regeneration, while its role in dental pulp senescence is unclear. We investigated the role of sclerostin in subculture-induced senescence of human dental pulp cells (HDPCs) and in the senescence-related decline of proliferation and odontoblastic differentiation. Methods Immunohistochemical staining and qRT-PCR analyses were performed to examine the expression pattern of sclerostin in young (20–30-year-old) and senescent (45–80-year-old) dental pulps. HDPCs were serially subcultured until senescence, and the expression of sclerostin was examined by qRT-PCR analysis. HDPCs with sclerostin overexpression and knockdown were constructed to investigate the role of sclerostin in HDPCs senescence and senescence-related impairment of odontoblastic differentiation potential. Results By immunohistochemistry and qRT-PCR, we found a significantly increased expression level of sclerostin in senescent human dental pulp compared with that of young human dental pulp. Additionally, elevated sclerostin expression was found in subculture-induced senescent HDPCs in vitro. By sclerostin overexpression and knockdown, we found that sclerostin promoted HDPCs senescence-related decline of proliferation and odontoblastic differentiation potential with increased expression of p16, p53 and p21 and downregulation of the Wnt signaling pathway. Discussion The increased expression of sclerostin is responsible for the decline of proliferation and odontoblastic differentiation potential of HDPCs during cellular senescence. Anti-sclerostin treatment may be beneficial for the maintenance of the proliferation and odontoblastic differentiation potentials of HDPCs.

Abstract
Inflammation is a physiological response to an injury or infection. It is supposed to be self-limiting, stopping when the situation recovers to normal to protect the tissue. This self-limiting action is called "resolution of inflammation". Currently, periodontitis is thought to be the result of failed resolution of inflammation; specifically, it is the result of excessive inflammation that leads to gingival recession and alveolar bone loss. In this review, we will focus on the processes of resolution of inflammation in periodontitis, which may be a therapeutic target of periodontitis.

Abstract
OBJECTIVE The aim of the present work was to study the prevention of liver cancer angiogenesis via miR-126. For this purpose, experimentations were conducted. MATERIALS AND METHODS The precursor sequence of miR-126 was amplified in the DNA of human liver cancer cell lines. We, therefore, constructed the overexpression and interference vectors of miR-126 in vitro; which were respectively transferred to liver cancer cells in the logarithmic phase and inoculated under both sides of the back skin of Balb/c-nu nude mice aged 4-6 weeks with 10 mu l (1 x 105) cell suspension. The experiment consisted of non-vector control group, miR-126 overexpression group, and miR-126 inhibition group. Eight weeks later, the mice were sacrified; the tumor volumes and serum ALT, AFP, VEGF levels were compared. VEGF expression, as well as the microvascular density of the liver tissues, was detected via immunohistochemistry. RESULTS Tumors volumes, serum ALT, AFP and VEGF levels and positive rates of VEGF were low in the miR-126 overexpression group and high in the miR-126 inhibition group, the difference being statistically significant (p < 0.05). CONCLUSIONS At the end of this study, we conclude that miR-126 inhibits liver cancer angiogenesis.

Abstract
OBJECTIVES To evaluate the diagnostic yield of prenatal whole exome sequencing (WES) for monogenic disorders in fetuses with structural malformations and normal results on cytogenetic testing, and to describe information on pathogenic variants that is provided by WES. METHODS Karyotyping, chromosomal microarray analysis (CMA) and WES were performed sequentially on stored samples from a cohort of 3949 pregnancies with fetal structural abnormalities detected on ultrasound and/or magnetic resonance imaging, referred between January 2011 and December 2015. Diagnostic rates of the three techniques were investigated overall, for phenotypic subgroups and for proband-only vs fetus-mother-father samples. Information on pathogenic variants was identified by WES. RESULTS Overall, 18.2% (720/3949) of fetuses had an abnormal karyotype. Pathogenic copy number variants were detected on CMA in 8.2% (138/1680) of fetuses that had a normal karyotype result. WES performed on a subgroup of 196 fetuses with normal CMA and karyotype results revealed the putative genetic variants responsible for the abnormal phenotypes in 47 cases (24%). The molecular diagnosis rates for fetus-mother-father and proband-only samples were 26.5% (13/49) and 23.1% (34/147), respectively. Variants of uncertain significance were detected in 12.8% (25/196) of fetuses, of which 22 were identified in the fetal proband-only group (15%; 22/147) and three in the fetus-mother-father group (6.1%; 3/49). The incidental finding rate was 6.1% (12/196). CONCLUSIONS WES is a promising method for the identification of genetic variants that cause structural abnormalities in fetuses with normal results on karyotyping and CMA. This enhanced diagnostic yield has the potential to improve the clinical management of pregnancies and to inform better the reproductive decisions of affected families. Copyright © 2017 ISUOG.

Abstract
Radiomics describes a broad set of computational methods that extract quantitative features from radiographic images. The resulting features can be used to inform imaging diagnosis, prognosis, and therapy response in oncology. However, major challenges remain for methodologic developments to optimize feature extraction and provide rapid information flow in clinical settings. Equally important, to be clinically useful, predictive radiomic properties must be clearly linked to meaningful biologic characteristics and qualitative imaging properties familiar to radiologists. Here we use a cross-disciplinary approach to highlight studies in radiomics. We review brain tumor radiologic studies (eg, imaging interpretation) through computational models (eg, computer vision and machine learning) that provide novel clinical insights. We outline current quantitative image feature extraction and prediction strategies with different levels of available clinical classes for supporting clinical decision-making. We further discuss machine-learning challenges and data opportunities to advance radiomic studies.

Abstract
Periodontal ligament cells (PDLCs), which have potential for multilineage differentiation, are candidates for use in regeneration of periodontal tissue defects; however, our understanding of the mechanisms underlying the lineage commitment of PDLCs remains limited. C4orf7, which is specifically expressed in the periodontal ligament (PDL) tissue, may be crucial in deciding the fate of PDLCs and regulating the periodontal bone balance. In this study, we examined the expression of C4orf7 in PDL tissue, using immunohistochemical staining. We transfected PDLCs with lentiviral vectors expressing C4orf7 and examined the effect of C4orf7 on the balance of PDLC osteogenic and osteoclastogenic differentiation. Osteogenic induction resulted in the downregulation of mRNA and protein expression levels of the osteogenic/cementoblastic markers: ALP, RUNX2, COL1, OPN, OPG, OSX, IBSP, CAP, and CEMP1. Transfected cells also exhibited an increased RANKL/OPG ratio, which is an indicator of osteoclastogenic differentiation. ALP activity assays and Alizarin red staining confirmed the negative effect of C4orf7 on PDLC osteogenic differentiation. Finally, we investigated the effect of C4orf7 on the lineage commitment of PDLCs to adipocytes. We observed increased expression levels of PPARγ2, GLUT4, ZFP423, FABP4, and LPL mRNAs, as well as a gradual accumulation of lipid droplets in the C4orf7-overexpressing group compared with controls. In summary, our data confirm that C4orf7 has an important role in the regulation of periodontal bone remodeling through promotion of the adipogenic/osteoclastogenic, and inhibition of the osteogenic/cementoblastic, differentiation of PDLCs. Therefore, C4orf7 is a potential therapeutic target for the treatment of periodontal disease and other bone metabolic disorders.

Abstract
Objective: To explore investigate the application of free medial thigh perforator flaps with different pedicle origins in the reconstruction of defect after radical resection of buccal mucosa squamous cell carcinoma. Methods: From January 2015 to December 2016, 32 cases with buccal mucosa squamous cell carcinoma underwent radical resection and buccal mucosa defect after surgery was reconstructed by free medial thigh perforator flap at the same stage. The patients included 32 males and 5 females, ranged in age from 36 to 71 years (45.2 years on average). According to UICC stage: T4N0M0 13 cases, T4N1M0 12 cases, T3N1M0 5 cases, T3N2M0 2 cases. The course ranged from 1 to 30 months (9.6 months on average). Results: The perforator flaps ranged from 8.0 cm×3.5 cm to 15.5 cm×6.0 cm in size, from 2.0 to 4.5 cm in thickness.The mean length of pedicles from gracilis muscle was (8.7±0.4) cm in 19 cases, the mean length of pedicles from adductor magnus muscle was (9.5±0.4) cm in 9 cases and the length of pedicles from femoral artery was (6.9±0.5) cm in 4 cases.All 44 perforator flaps survived uneventfully. The donor sites in the medial thigh were closed directly and healed well in all cases. Patients were followed up for 8 to 32 months with satisfied esthetic and functional results in reconstructed tongue, with no local recurrence. Only linear scars left in the donor sites, the functions of thighs were not affected. Conclusion: The free medial thigh perforator flap is an idea choice to reconstruct the defect after radical resection of buccal mucosa squamous cell carcinoma.

Abstract
Objective: To investigate the application of free medial thigh chimeric myocutaneous perforator flap in the reconstruction of tongue defect after radical resection of tongue carcinoma. Methods: From June 2013 to November 2015, 17 cases with tongue carcinoma underwent radical resection and tongue and mouth floor defects after surgery were reconstructed with medial thigh chimeric myocutaneous perforator flaps at the same stage. These 17 cases included tongue carcinoma on lingual margin (n=9), ventral tongue (n=7) and mouth floor (n=1). Appearance and functional results were evaluated with follow-up. Results: Medial thigh chimeric myocutaneous perforator flap was (9.0±0.3) cm in length, (4.5±0.3) cm in width , and (1.8±0.4) cm in thickness. The length of pedicle was (7.4±0.6) cm. All of the 17 flaps survived uneventfully, and the donor sites were closed directly in all cases. All patients were followed up for 10-28 months with satisfied esthetic and functional results in reconstructed tongue. Aside from linear scar in the donor sites, the functions of thighs were not affected. No local recurrence occurred. Conclusion: The free medial thigh chimeric myocutaneous perforator flap is an ideal choice to reconstruct the tongue and mouth floor defect after radical resection of tongue carcinoma.

Abstract
The presynaptic cytomatrix protein Piccolo, encoded by PCLO, is frequently mutated and amplified in esophageal squamous cell carcinoma (ESCC), but its exact roles in ESCC remain unclear. Here we report that Piccolo expression correlates significantly with clinical stage, patient survival and tumor embolus. Functional studies demonstrate that PCLO knockdown remarkably attenuates ESCC malignancy in vitro and in vivo, and ectopic EGFR expression partially compensates for Piccolo loss. PCLO knockdown promotes ubiquitination and degradation of EGFR, which is associated with the negative regulatory effect of Piccolo on E3 ligase Siah1. An anti-Piccolo monoclonal antibody inhibited tumor proliferation in a mouse model of ESCC. These results demonstrate that Piccolo contributes to tumor aggressiveness in ESCC, likely by stabilizing EGFR and promoting EGFR-dependent signaling. Our results further suggest that Piccolo may represent a novel prognostic biomarker and therapeutic target for patients with ESCC.

Abstract
OBJECTIVE The aim of this study is to enhance the understanding of frequent blood donors' characteristics and devise strategies to achieve an optimal blood inventory. BACKGROUND Apart from donor recruitment and retention, an effective way to increase blood supply is to increase the donation frequency among donors. Understanding the characteristics of frequent donors will be helpful to impact their future donation pattern, which would in turn achieve a stable and adequate blood inventory to meet the changing demands of the society. METHODS AND MATERIALS Demographic information of blood donors for each donation in Hong Kong (HK) was routinely collected and stored in the database of Hong Kong Red Cross Blood Transfusion Service. Logistic regression models (by gender group) with interaction effects were constructed to analyse the differences in the likelihood of being frequent donors and the associations with their demographic characteristics. RESULTS A total of 158,666 blood donors in 2010 gave 227,634 donations during the study. In general, male donors were more likely to be frequent donors. Logistic regression models further identified the characteristics of frequent donors in HK: older, blood type Rh D-ve and repeat donors, although their extent of impact was different for different gender group. CONCLUSION To achieve an optimal blood inventory to meet the challenge of ageing in the society, donors who donate less often should be targeted to increase their donation frequency. More efforts in promotion should be made to recruit those non-donors to join the blood donation pool and motivate 'targeted' existing donors in the population to participate blood donation more regularly.

Abstract
OBJECTIVE To evaluate the clinical performance of non-invasive prenatal testing (NIPT) in detecting fetal copy number variants (CNVs). METHODS NIPT of cell-free fetal DNA was performed retrospectively, using stored maternal plasma, at an average gestational age of 21.1 weeks in 117 pregnant women who had previously undergone invasive prenatal testing for chromosome microarray analysis (CMA). Among the fetal samples tested by CMA, 18 had positive results (CNVs > 1 megabase (Mb)) and 99 had negative results (CNVs < 1 Mb or without CNVs detected). The results of NIPT and CMA were then compared. RESULTS In the 11 CMA-positive samples with CNVs > 5 Mb, the detection rate of CNVs was 90.9%; the one case missed by NIPT had a fetal fraction of 4.7%. For the other seven CMA-positive samples with CNVs < 5 Mb, the detection rate was 14.3%; only one case with a 2.82-Mb duplication was detected, with a fetal fraction of 26.7%. For 35.7% (5/14) of CNVs detected by both NIPT and CMA, the differences in fragment length were within ± 1 Mb. In this study, the overall sensitivity and specificity of NIPT for detecting CNVs > 1 Mb were 61.1% and 95.0%, respectively, with a false-positive rate of 5.0%. CONCLUSIONS Our results demonstrate that NIPT for common aneuploidies can detect fetal CNVs > 5 Mb with high sensitivity, provided that fetal fraction is high enough, without increasing sequencing depth. The detection power of NIPT is determined mostly by fetal fraction and CNV size. A positive NIPT screening result for CNVs must be interpreted with caution and validated by additional diagnostic study.

Abstract
Aim To evaluate the outcome of arthroscopy treatment using high-strength line in the treatment of tibial avulsion fracture of posterior cruciate ligament. Methods Both the avulsed bone block and the tibia bone bed were refreshed. The procedure was completed with the assistance of PCL director drill guide. The reduction and fixation using high-strength line were used to fix the avulsed bone by from posterior middle portal. Rehabilitation began early postoperatively. Results From January 2010 to June 2012, a total of 18 arthroscopically treated cases of PCL tibial avulsion fracture were retrospectively evaluated. Reduction of the avulsion fragment was obtained in all cases. 16 cases were followed up for 7–30 months (average 13.6), and 2 cases were out of follow-up. In the 16 followed patients, flexion and extension were back to normal within 6 weeks, and return to normal walk in 12 weeks. The bone healing was good without any vascular or nerve complications. All the patients regained the preinjury activity level. The mean score (and standard deviation) increased from 38.9 ± 4.9 points to 95.2 ± 3.8 points with the system of Lysholm, from 57.1 ± 10.3 points to 94.3 ± 4.4 points with the system of IKDC. Post-test displacement of KT3000 declined from 3.6 ± 0.39 to 1.1 ± 0.27 mm. Conclusion Arthroscopic vertical fixation by high-strength line is a simple, safe, reliable, and micro-invasive treatment to PCL tibial avulsion fracture. It is a kind of real all arthroscopic technique, and good for early postoperative rehabilitation. The total stability of the knee could be gained, and the second operation to remove the internal fixation is avoided.

Abstract
Change in tumor size estimated using longitudinal tumor growth inhibition (TGI) modeling is an early predictive biomarker of clinical outcomes for multiple cancer types. We present the application of TGI modeling for subjects with multiple myeloma (MM). Longitudinal time course changes in M‐protein data from relapsed and/or refractory MM subjects who received single‐agent carfilzomib in phase II studies (n = 456) were fit to a TGI model. The tumor growth rate estimate was similar to that of other anti‐myeloma agents, indicating that the model is robust and treatment‐independent. An overall survival model was subsequently developed, which showed that early change in tumor size (ECTS) at week 4, Eastern Cooperative Oncology Group performance status (ECOG PS), hemoglobin, sex, percent bone marrow cell involvement, and number of prior regimens were significant independent predictors for overall survival (P < 0.001). ECTS based on M‐protein modeling could be an early biomarker for survival in MM following exposure to single‐agent carfilzomib.
