Abstract
This study investigates the therapeutic potential of electroacupuncture (EA) on obesity, focusing on its influence on autophagy and energy metabolism, utilizing a high-fat diet (HFD)-induced mouse model. Treatment with EA significantly reduces body weight, fat deposition, and lipid accumulation in HFD-fed mice. Additionally, EA effectively ameliorates metabolic imbalances, reducing blood glucose levels and plasma markers of liver function. At the molecular level, EA enhances the expression of thermogenesis-associated genes in brown adipose tissue and decreases p53 expression, suggesting a decrease in apoptosis. Autophagy in white adipose tissue is inhibited by EA, as demonstrated by the suppression of key autophagy-related proteins. Further experiments highlight the critical role of Sirtuin 3 (Sirt3) in EA's anti-obesity effects. Sirt3 supplementation combined with EA results in reduced body weight, fat deposition, and lipid accumulation, along with modulations in key metabolic indicators. Moreover, EA's modulatory effect on uncoupling protein 1 (Ucp1), Peroxisome proliferator-activated receptor gamma coactivator 1-alpha (Pgc-1α), and p53 is found to be Sirt3 dependent. In conclusion, EA exerts beneficial effects against obesity through Sirt3-dependent modulation of autophagy and energy metabolism, indicating a potential therapeutic approach for obesity and related metabolic disorders.

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
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
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
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.

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
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
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.

Abstract
We present results from the first demonstration of a fully integrated SDN-controlled bandwidth-flexible and programmable SDM optical network utilizing sliceable self-homodyne spatial superchannels to support dynamic bandwidth and QoT provisioning, infrastructure slicing and isolation. Results show that SDN is a suitable control plane solution for the high-capacity flexible SDM network. It is able to provision end-to-end bandwidth and QoT requests according to user requirements, considering the unique characteristics of the underlying SDM infrastructure.

Abstract
We demonstrate here a method that perfuses a small region of an organotypic hippocampal culture with a solution containing an enzyme substrate, a neuropeptide. Perfusate containing hydrolysis products is continually collected and subsequently analyzed for the products of the enzymatic degradation of the peptide substrate. The driving force for perfusion is an electric field. The fused silica capillaries used as "push" and "pull" or "source" and "collection" capillaries have a ζ-potential that is negative and greater in magnitude than the tissue's ζ-potential. Thus, depending on the magnitudes of particular dimensions, the electroosmotic flow in the capillaries augments the fluid velocity in the tissue. The flow rate is not directly measured; however, we determine it using a finite-element approach. We have determined the collection efficiency of the system using an all d-amino acid internal standard. The flow rates are low, in the nL/min range, and adjustable by controlling the current or voltage in the system. The collection efficiency of the d-amino acid peptide internal standard is variable, increasing with increased current and thus electroosmotic flow rate. The collection efficiency can be rationalized in the context of a Peclet number. Electroosmotic push-pull perfusion of the neuropeptide galanin (gal1-29) through the extracellular space of an organotypic hippocampal culture results in its hydrolysis by ectopeptidase reactions occurring in the extracellular space. The products of hydrolysis were identified by MALDI-MS. Experiments at two levels of current (8-12 μA and 19-40 μA) show that the probability of seeing hydrolysis products (apparently from aminopeptidases) is greater in the Cornu Ammonis area 3 (CA3) than in the Cornu Ammonis area 1 (CA1) in the higher current experiments. In the lower current experiments, shorter peptide products of aminopeptidases (gal13-29 to gal20-19) are seen with greater frequency in CA3 than in CA1 but there is no statistically significant difference for longer peptides (gal3-29 to gal12-29).

Abstract
We have developed a novel sampling technique that allows both introduction and removal of fluid from the extracellular space of living tissue. This method is based on the fluidics of push-pull perfusion but flow is driven by electroosmosis. We have applied this method to organotypic hippocampal cultures. A source capillary is inserted into the tissue and a collection capillary is in contact with the tissue surface through a thin layer of fluid. A voltage is applied across the proximal ends of source and collection capillary. In the applied field, fluid will move from source, into the tissue, and then be collected. In this process, damage to cells may occur. To understand better what sampling conditions influence damage most, we tested various sampling geometries and applied voltages, quantifying damage 16-24 h later using propidium iodide as a cell death marker. We found that damage correlates with both voltage drop and power dissipated in the tissue, but that voltage drop is a better indicator of damage when comparing models in which capillary arrangement and length are different.
