Abstract
Objective: To investigate the clinical efficacy and safety of ferric derisomaltose injection versus iron sucrose injection in the treatment of iron deficiency anemia (IDA) . Methods: A total of 120 patients with iron deficiency anemia admitted from June 2021 to March 2023 were given intravenous iron supplementation with ferric derisomaltose to assess the efficacy and safety of hemoglobin (HGB) elevation before and after treatment. Simultaneously, the clinical effects of iron supplementation with iron sucrose were compared to those of inpatient patients during the same period. Results: Baseline values were comparable in both groups. Within 12 weeks of treatment, the elevated HGB level in the ferric derisomaltose group was higher than that of the iron sucrose group, with a statistical difference at all time points, and the proportion of HGB increased over 20 g/L in the patients treated for 4 weeks was higher (98.7%, 75.9% ). During the treatment with ferric derisomaltose and iron sucrose, the proportion of mild adverse reactions in the ferric derisomaltose group was slightly lower than that of the iron sucrose group, and neither group experienced any serious adverse reactions. The patients responded well to the infusion treatment, with no reports of pain or pigmentation at the injection site. Conclusion: The treatment of IDA patients with ferric derisomaltose has a satisfactory curative effect, with the advantages of rapidity, accuracy, and safety. Therefore, it is worthy of widespread clinical use.

Abstract
Proanthocyanidins (PCs) are a class of polyphenols that are composed of flavanate monomers and their polymers, which have antibacterial and anti-inflammatory properties with very few side effects. This article reviews the mechanism by which PCs differentially regulate microbiota, reshape microflora diversity and play a role in suppressing inflammation, providing a reference for the basic research of PCs in improving female vaginal health, and is expected to provide a new idea and breakthrough for the combined use of PCs with other antibacterial drugs in the treatment of vaginitis.

Abstract
Objective: This study aimed to investigate the role and clinical significance of MUC4 gene mutations in thrombotic events in patients with classic paroxysmal nocturnal hemoglobinuria (PNH) patients. Methods: A retrospective analysis was conducted on the clinical data and gene sequencing results of 45 patients with classic PNH admitted to the Department of Hematology, Tianjin Medical University General Hospital, from June 2018 to February 2022. MUC4 gene mutations in patients with classic PNH were summarized, and the risk factors for thrombotic events in these patients were analyzed. Additionally, the effects of MUC4 gene mutations on the cumulative incidence and survival of thrombotic events in patients with classic PNH were determined. Results: The detection rate of MUC4 gene mutations in patients with classic PNH who experienced thrombotic events (thrombotic group) was 68.8% (11/16), which was significantly higher than that in the non-thrombotic group [10.3% (3/29) ] (P<0.001). All mutations occurred in exon 2. MUC4 mutation (OR=20.815, P=0.010) was identified as an independent risk factor for thrombotic events in patients with classic PNH. The cumulative incidence of thrombotic events was 78.6% (11/14) in the MUC4 gene mutation group (mutation group) and 16.1% (5/31) in the non-mutation group, showing a statistically significant difference between the two groups (P<0.001). Survival analysis showed a lower overall survival (OS) rate in the thrombotic group compared with that in the non-thrombotic group [ (34.4±25.2) % vs. (62.7±19.3) % ] (P=0.045). The OS rate of patients was (41.7±29.9) % in the mutation group and (59.1±18.3) % in the non-mutation group (P=0.487) . Conclusion: MUC4 gene mutations are associated with an increased incidence of thrombotic events in classic PNH patients, highlighting their role as independent risk factors for thrombosis in this population. These mutations can be considered a novel predictive factor that aids in evaluating the risk of thrombosis in patients with classic PNH.

Abstract
Objective: To examine the clinical effect of auxiliary liver transplantation with ultra-small volume graft in the treatment of portal hypertension. Methods: Twelve cases of portal hypertension treated by auxiliary liver transplantation with small volume graft at Liver Transplantation Center,Beijing Friendship Hospital, Capital Medical University between December 2014 and March 2022 were studied retrospectively. There were 8 males and 4 females,aged 14 to 66 years. Model for end-stage liver disease scores were 1 to 15 points and Child scores were 6 to 11 points. The grafts was derived from living donors in 9 cases,from split cadaveric donors in 2 cases,from whole cadaveric liver of child in 1 case. The graft recipient body weight ratios of 3 cadaveric donor livers were 0.79% to 0.90%, and of 9 living donor livers were 0.31% to 0.55%.In these cases, ultra-small volume grafts were implanted. The survivals of patient and graft, complications, portal vein blood flow of residual liver and graft, abdominal drainage and biochemical indexes of liver function were observed. Results: All the grafts and patients survived. Complications included outflow tract torsion in 2 cases, acute rejection in 1 case, bile leakage in 1 case, and thyroid cancer at the later stage of follow-up in 1 case, all of which were cured. The torsion of outflow tract was attributed to the change of anastomotic angle after the growth of donor liver. After the improvement of anastomotic method, the complication did not recur in the later stage. There was no complication of portal hypertension. The measurement of ultrasonic portal vein blood flow velocity showed that the blood flow of residual liver decreased significantly in the early stage after operation, and maintained a very low blood flow velocity or occlusion in the long term after operation, and the blood flow of transplanted liver was stable. Conclusions: Auxiliary liver transplantation can implant ultra-small donor liver through compensation of residual liver. This method may promote the development of living donor left lobe donation and split liver transplantation. However, the auxiliary liver transplantation is complex, and it is difficult to control the complications. Therefore, this method is currently limited to centers that are skilled in living related liver transplantation and that have complete ability to monitor and deal with complications.

Abstract
Rheumatoid arthritis (RA) is a most common chronic joint disease belonging to inflammatory autoimmune disease. The aim of this study was to determine the role and mechanism of bone marrow mesenchymal stem cells (BMSCs)-derived exosomes and fibrinogen-like protein 1 (FGL1) overexpression exosomes shuttled by BMSCs (FGL1-Exos) on RA. All of the exosomes were visualized by transmission electron microscope (TEM) and the characteristic proteins were detected by western blot. To investigate the therapeutic effect of FGL1-Exos, RA-FLSs were activated by TNF-α and RA rat model was established by collagen incomplete Freund's adjuvant. Cell viability, apoptosis, inflammation factors, and protein levels were detected by CCK-8, flow cytometry, enzyme-linked immunosorbent assay and western blot, respectively. Hematoxylin and eosin and safranin O staining were used to detect the histopathology changes. Cell apoptosis and FGL1 expression in knee joint were detected by immunofluorescence. The results showed that FGL1-Exos could inhibit the cell viability meanwhile increase the cell apoptosis in RA-FLSs. Meanwhile, FGL1-Exos could effectively suppress the inflammation score, joint destruction, and inflammatory response in RA rat model. FGL1-Exos directly inhibited cell apoptosis of RA-FLSs and RA rat model by suppressing the inflammatory cytokines, specific rheumatoid markers, immunological markers meanwhile meditating the NF-κB pathway. Our results indicate that FGL1 was a therapeutic potential target in RA therapy.

Abstract
This study aimed to investigate the intermediate-term efficacy of nonosteotomy approaches in the treatment of early to intermediate stage ankle osteoarthritis (OA). Forty-two patients received treatment for early to intermediate stage ankle osteoarthritis with nonosteotomy approaches were reviewed. The surgical satisfaction was evaluated at 1 year after surgery and the last follow-up period; the American Orthopaedic Foot and Ankle Society (AOFAS) scale and Visual Analog Scale (VAS) were employed for the evaluation of function and pain, respectively, and the stage of ankle osteoarthritis was determined. At 1 year surgery and the last follow-up period, the surgical satisfaction was 37 (88.1%) and 35 (83.3%), respectively, and the favorable function was noted in 34 (80.9%) and 32 (76.2%), respectively. The AOFAS score significantly increased from 50.62 ± 10.81 (range 30-60) before surgery to 81.43 ± 12.00 (range 75-95) at 1 year after surgery (p < .0001) and 79.67 ± 10.34 (range 70-96) at the last follow-up period (p < .0001 vs before surgery; p = .107 vs 1 year). The VAS score reduced from 5.07 ± 1.57 (range 4-7) before surgery to 1.97 ± 1.41 (range 0-3) at 1 year (p < .0001) and 1.80 ± 1.15 (range 0-3) at the last follow-up period (p < .0001 vs before surgery; p = .265 vs 1 year). Moreover, the AOFAS score and VAS score in patients with ankle osteoarthritis at different stages were improved significantly after surgery (p < .0001). Intermediate-term follow-up period shows that nonosteotomy approaches are able to relieve pain and improve postoperative function in the treatment of early to intermediate stage ankle osteoarthritis; the improvement determined according to imaging examination is not completely consistent with that determined based on clinical function.

Abstract
OBJECTIVE The purpose of this study was to explore the effects of Kruppel like factors 11 (KLF11) on oxidative stress, apoptosis, and endoplasmic reticulum stress (ERS) in osteoarthritis (OA) and its mechanism. PATIENTS AND METHODS Human articular cartilage tissue was used to study the correlation between KLF11 and OA. Furthermore, human chondrocytes were used to explore the effects of KLF11 on oxidative stress, apoptosis, and ERS in chondrocytes by overexpressing KLF11 and using the OA inducer IL-1β. The p38MAPK signaling pathway agonist P79350 was used to study the effect of KLF11 on the p38 MAPK signaling pathway. RESULTS Articular cartilage tissue in OA patients and IL-1β-induced chondrocytes expressed higher KLF11. Overexpression of KLF11 significantly reduced oxidative stress levels, apoptosis levels, and activity of ERS-related pathways in chondrocytes. Moreover, P79350 attenuated the protective effect of KLF11 on chondrocytes by activating the p38MAPK signaling pathway. CONCLUSIONS KLF11 protects against OA by inhibiting oxidative stress, apoptosis, and ERS in chondrocytes by inhibiting p38MAPK signaling pathway.

Abstract
Background Although efficacy is related to many factors, the surgical approach is one of the most important intervention factors for complex ankle fractures. Ankle fractures involving the distal tibial plafond frequently present a surgical challenge in choosing which incisions will be best for surgical treatment. Here, we present an innovative fibular notch approach for the treatment of some specific ankle fractures and present a series of patients with either functional or radiographic outcomes. Methods Twenty-two patients with distal tibial plafond fractures with concomitant fibular and distal tibiofibular syndesmosis injuries were treated through a fibular notch approach in this retrospective study. The details of the surgical technique were reviewed from the operative notes. Relevant data were reviewed from the medical records. The quality of fractures and syndesmosis reduction was examined using CT scans, and lateral stability of the ankle was assessed by physical examination and stress radiographs. The American Orthopedic Foot and Ankle Society Ankle-Hindfoot Scale (AOFAS) score was implemented for clinical functional assessment. Results All surgeries were successfully performed via the fibular notch approach as the primary approach with excellent intraoperative visualization. Postoperative radiography revealed satisfying restoration of all fractures and syndesmosis. All fractures healed with an average time of 17.3 ± 3.6 weeks. Mild posttraumatic osteoarthritis (PTOA) was present in 4 patients. The average AOFAS score was 88.8 at the last follow-up. Conclusions The fibular notch approach is a safe and reliable approach for the treatment of specific ankle fractures involving the distal tibial plafond. This approach provides excellent direct visualization of the fragments and articular surface without significantly increasing iatrogenic injuries. Satisfactory radiographic and clinical results were observed, and further clinical and anatomical studies are recommended to ascertain the feasibility of this approach in the treatment of complex distal tibial fractures.

Abstract
Gustilo grade IIIB open tibial fractures are relatively difficult to treat. We investigated the treatment effects of tibial intramedullary nails combined with vacuum sealing drainage (VSD) for Gustilo grade IIIB open tibial fractures. From March 2015 to March 2017, 13 cases of Gustilo grade IIIB open tibial fractures were treated with Expert Tibial Nails combined with VSD. Causes of injury included falls from a height (n = 9, 69.2%) and road accidents (n = 4, 30.8%). The duration from time of injury to hospital intake was 7.3 hours (range 5 to 9.5), and the time between injury and operation was 6.7 days (range 3 to 11). Six months after the operation, overall patient general health was investigated via the American Orthopaedic Foot and Ankle Society (AOFAS) ankle score and the physical and mental health dimensions of the Short-Form Health Survey 36 (SF-36). Postoperative complications and infections also were recorded. The results indicated that the median AOFAS score was 93.7 (range 89 to 97), with all individuals having either excellent (90 to 100; n = 10, 76.9%) or good (80 to 89; n = 3, 23.1%) outcomes. The median physical SF-36 score was 83.1 (range 72.5 to 93.0), and the median mental SF-36 score was 80.6 (range 69.7 to 92.0). Moreover, there were no instances of tibial shortening, neurovascular injury, postoperative complications, implant failure, malunion, or serious infections. In conclusion, intramedullary tibial nail combined with VSD is a safe and effective method to treat type grade IIIB open tibial fractures.

Abstract
OBJECTIVE This study aims to explore whether the inhibitory role of metformin could inhibit LPS-induced inflammatory response in vascular smooth muscle cells (VSMCs) and its underlying mechanism. MATERIALS AND METHODS VSMCs were extracted from aorta of Sprague Dawley rats. MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assay was performed to detect VSMCs viability after treatment with different concentrations of metformin. Levels of monocyte chemoattractant protein-1 (MCP-1), interleukin 6 (IL-6) and tumor necrosis factor-α (TNF-α) in VSMCs were detected by ELISA (enzyme-linked immunosorbent assay) and qRT-PCR (quantitative Real time-polymerase chain reaction). Protein and mRNA levels of toll like receptor 4 (TLR4) and peroxisome proliferators activated receptor γ (PPAR-γ) in VSMCs were detected by Western blot and qRT-PCR, respectively. Finally, VSMCs were treated with the PPAR-γ antagonist GW9662 and inflammatory indicators in cells were detected. RESULTS No significant difference in VSMCs viability was found after 0-2 mM metformin treatment or 500 μg/L LPS induction for 24 h. After 500 μg/L LPS induction in VSMCs for 24 h, levels of MCP-1, TNF-α and IL-6 were remarkably elevated. Both mRNA and protein levels of TLR4 in VSMCs were upregulated after 500 μg/L LPS induction for 24 h, which were remarkably reversed by the treatment of different concentrations of metformin. Knockdown of TLR4 remarkably inhibited LPS-induced inflammatory response in VSMCs, manifesting as decreased levels of MCP1, TNF-α and IL-6, which were further downregulated after combination treatment of TLR4 knockdown and 20 mM metformin. Furthermore, both mRNA and protein levels of PPAR-γ in VSMCs were downregulated after 500 μg/L LPS induction for 24 h, which were remarkably reversed by the treatment of different concentrations of metformin. GW9662 treatment resulted in elevated expressions of MCP-1, TNF-α and IL-6, which were reversed by metformin treatment. CONCLUSIONS Metformin can effectively inhibit the mRNA and protein expressions of IL-6, MCP-1, and TNF-α in LPS-induced VSMCs. The anti-inflammatory effects of metformin inhibit the inflammatory response through downregulating rely on the downregulation of TLR4 expression and upregulation ofng PPAR-γ activity.

Abstract
BACKGROUND To compare the mechanical characteristics of a percutaneous superior pubic intramedullary screw, percutaneous bridging plate and percutaneous screw-rod system of the anterior ring for the treatment of unilateral vertical pubic fractures to provide a reference for clinical application. METHODS A finite element model of pelvic anterior ring injury (unilateral vertical pubic fracture) was produced. The fractures were fixed with a percutaneous superior pubic intramedullary screw, percutaneous bridging plate and percutaneous screw-rod system of the anterior ring and their combinations in 5 types of models. The fracture stabilities under vertical, bilateral and anterior-posterior load were quantified and compared based on the displacement of the hip joints' midpoint as quantificational index of fracture stability. RESULTS In the condition of bilateral and anterior-posterior load, the vertical, bilateral and anterior-posterior displacements of the hip joints' midpoint of different models were significantly different respectively. In general, the displacements of the 5 pelvic anterior ring fixations were ranked from maximum to minimum as follows: bridging plate, pelvic anterior screw-rod system, combination of bridging plate and pelvic anterior screw-rod system, superior pubic intramedullary screw and combination of superior pubic intramedullary screw and pelvic anterior screw-rod system. CONCLUSION For the fixation in unilateral pubic fractures of pelvic ring injury, the percutaneous superior pubic intramedullary screw is optimal, the percutaneous pelvic anterior screw-rod system is the second choice, and percutaneous bridging plate ranks the third. The percutaneous pelvic anterior screw-rod system can significantly increase fixation stability of the percutaneous superior pubic intramedullary screw and the percutaneous bridging plate.

Abstract
Fruit neck length (FNL) is an important quality trait in cucumber because it directly affects its market value. However, its genetic basis remains largely unknown. We identified a candidate gene for FNL in cucumber using a next-generation sequencing-based bulked segregant analysis in F2 populations, derived from a cross between Jin5-508 (long necked) and YN (short necked). A quantitative trait locus (QTL) on chromosome 7, Fnl7.1, was identified through a genome-wide comparison of single nucleotide polymorphisms between long and short FNL F2 pools, and it was confirmed by traditional QTL mapping in multiple environments. Fine genetic mapping, sequences alignment and gene expression analysis revealed that CsFnl7.1 was the most likely candidate Fnl7.1 locus, which encodes a late embryogenesis abundant protein. The increased expression of CsFnl7.1 in long-necked Jin5-508 may be attributed to mutations in the promoter region upstream of the gene body. The function of CsFnl7.1 in FNL control was confirmed by its overexpression in transgenic cucumbers. CsFnl7.1 regulates fruit neck development by modulating cell expansion. Probably, this is achieved through the direct protein-protein interactions between CsFnl7.1 and a dynamin-related protein CsDRP6 and a germin-like protein CsGLP1. Geographical distribution differences of the FNL phenotype were found among the different cucumber types. The East Asian and Eurasian cucumber accessions were highly enriched with the long-necked and short-necked phenotypes, respectively. A further phylogenetic analysis revealed that the Fnl7.1 locus might have originated from India. Thus, these data support that the CsFnl7.1 has an important role in increasing cucumber FNL.

Abstract
OBJECTIVE The objective of this study was to examine the clinical and magnetic resonance imaging (MRI) outcomes of extensive tenosynovectomy on patients with diffuse flexor hallucis longus tenosynovitis combined with effusion (DFHLT-E). METHODS Consecutive patients undergoing extensive tenosynovectomy for DFHLT-E in the same foot and ankle center from January 2013 to December 2016 were selected; a total of 14 patients were included in the final analysis. Patients with a minimum 1-year follow-up were evaluated with physical examination, MRI, American Orthopaedic Foot and Ankle Society (AOFAS) clinical midfoot scale, and visual analog scale (VAS) pain scores. RESULTS The 14 patients were followed up for an average of 15.0 ± 2.3 months (12-18 months). There were no recurrences in all clinical examinations at the final follow-up. The AOFAS score was improved from 61.57 ± 10.70 before surgery to 90.28 ± 9.41 at the final follow-up. The difference was statistically significant (p = 0.001). The VAS score was improved from 4.00 ± 0.82 before surgery to 0.43 ± 0.53 at the final follow-up (p < 0.001). MRI examination revealed two patients with small residual and limited effusion with no clinical symptoms. Superficial pin infection was observed in one patient, and two patients had transient neurostimulation. CONCLUSIONS Extensive tenosynovectomy is an effective alternative for the treatment of DFHLT-E with less complications or recurrence.

Abstract
Objective To investigate the clinical effect of robot-assisted treatment of unstable pelvic fractures through a percutaneous iliac lumbar double rod fixation combined with a percutaneous pelvic anterior ring INFIX (internal fixator) fixation. Methods This was a retrospective analysis of 17 cases of unstable anterior and posterior pelvic ring fractures treated between April 2016 and October 2018 by the third Ti-robot system produced in China. The posterior ring was supported with an iliac lumbar double rod fixation and the anterior ring with an INFIX fixation. Operation time and peri-operative bleeding were recorded. The reduction of pelvic fracture displacement was evaluated by Matta score, the post-operative results were evaluated according to Majeed score, and the complications were recorded. Results Twelve males and five females, aged 21–71 years (mean 40.1 ± 3.8 years) were followed up for three to 12 months, (median 6.7 months). Tile typing showed seven B1 type, two B2 type, and eight C1 type cases. Operation time was 90–160 minutes (mean 112.9 ± 16.8 minutes), bleeding was 80–150 mL (mean 105.9 ± 20.6 mL). X-ray three to five days after operation was evaluated by Matta score as excellent in 15 and good in two cases. Majeed score at last follow-up was 85–98 points, excellent in 17 cases. Two cases of lower extremity deep vein thrombosis received an inferior vena cava filter. The filters were removed after two weeks. One case showed incision fat liquefaction healing and the wound healed three weeks after surgery. Conclusion Orthopedic robot-assisted treatment of unstable pelvic fractures by a percutaneous iliac lumbar double rod fixation and a percutaneous pelvic anterior ring INFIX fixator was minimally invasive and feasible. A prospective study is needed.

Abstract
BACKGROUND The purpose of this study was to compare the clinical and radiographic outcomes of stabilization of the lateral ligament combined with joint debridement in patients with ligamentous moderate neutral ankle osteoarthritis with those achieved for patients with varus ankle osteoarthritis. METHODS We reviewed integrated data from 40 patients (40 ankles) with ligamentous moderate ankle osteoarthritis. Matched for age, gender, and follow-up duration, they were divided into two groups by preoperative coronal plane hindfoot moment arm values (HMAV): neutral (20 ankles, ≤15 mm) and varus (20 ankles, >15 mm) deformity. Stabilization of lateral ligament combined with joint debridement was performed. American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hind foot score, hindfood moment arm values, and classification of Takakura were used to compare clinical and radiographic outcomes after a mean follow-up period of 64.2 months (range, 60-84 months). RESULTS Mean post-operative AOFAS was 86.0 and 72.6 in the neutral and varus groups, respectively. The post-operative AOFAS of both groups improved significantly, although the outcome improvement of the neutral group was better than that of the varus group (P = 0.0006). There was obvious improvement in HMAV of the neutral group (P = 0.0469) and less improvement in HMAV of the varus group (P = 0.8509). The mean postoperative HMAV was 4.60 mm (0-10 mm) and 17.85 mm (8-23 mm) in the neutral and varus groups, respectively. The radiographic classification of Takakura was unchanged in the neutral group, whereas four cases in the varus group had a worse classification. CONCLUSIONS Stabilization of the lateral ligament combined with joint debridement for ligamentous moderate ankle osteoarthritis showed better clinical and radiographic outcomes in patients with neutral alignment than that achieved for patients with varus malalignment.

Abstract
Background Although supramalleolar osteotomy is the main joint-preserving method for the treatment of varus ankle osteoarthritis, it tends to be ineffective when ankle osteoarthritis presents in combination with an excessive talar tilt angle. The purpose of this study was to present a new surgical technique, supramalleolar osteotomy combined with lateral ligament reconstruction and talofibular immobilization, for the treatment of varus ankle osteoarthritis with an excessive talus tilt angle and to evaluate the clinical and radiological results. Methods From January 2013 to October 2016, a total of 17 patients with 17 cases of varus ankle arthritis with excessive talar tilt angles (larger than 7.3°) underwent surgical treatment using our new technique. The American Orthopaedic Foot and Ankle Society (AOFAS) clinical ankle-hindfoot scale and a visual analogue scale (VAS) were used to evaluate ankle function and pain before surgery and at the last follow-up. The medial distal tibial angle (MDTA), anterior distal tibial angle (ADTA), talar tilt angle (TTA), and hindfoot moment arm values (HMAVs) were evaluated on weight-bearing radiographs acquired preoperatively and at the last follow-up. Results The AOFAS score improved significantly from 45.8 ± 2.1 before surgery to 84.8 ± 1.8 after surgery (p < 0.001), and the VAS score decreased from 4.9 ± 0.4 to 1.1 ± 0.2 (p < 0.001). The MDTA, TTA, and HMAV changed from 80.9° ± 0.4° to 90.1° ± 0.4°, 11.7° ± 0.6° to 1.4° ± 0.3°, and 12.6 mm ± 0.8 mm to 4.2 mm ± 0.6 mm, respectively (each p < 0.001). The ADTA showed no obvious change (p = 0.370). The staging of 11 cases (65%) improved. Intramuscular vein thrombosis of the lower limbs occurred in 1 patient 1 week after surgery, and superficial infection occurred in 1 patient. Conclusions Supramalleolar osteotomy combined with lateral ligament reconstruction and talofibular immobilization can correct the load of the weight-bearing ankle and effectively improve the ankle function. As the talar tilt angle can be significantly improved after surgery, this technique can be used for the treatment of varus ankle osteoarthritis with an excessive TTA.

Abstract
Objective: To explore the distribution and intensity of kitchen waste treatment plant, providing scientific basis for occupational diseases prevention and treatment in that industry. Methods: 30 operating personnel in a kitchen waste disposal enterprise were selected as the research group and 16 non-operating personnel as the control group. The epidemiological survey was carried out in June 2015 and July 2016, and the results of occupational hazards and occupational health monitoring during 2015 to 2017 were analyzed. Results: The results of various occupational hazards factors during 2015 to 2017 were all in accordance with the occupational health limit, but the results of occupational health examination were abnormal. The occupational correlation could not be ruled out by the abnormality of electrical audiometry, electrocardiogram and Department of Dermatology examination. Conclusion: Workers in kitchen waste treatment plant are likely to suffer low-intensity, continuous health damage. There is occupational health risk in that industry. The accumulation of basic information and the improvement of relevant standards and methods are needed for further study.

Abstract
Acceptor-sensitised 3-cube fluorescence resonance energy transfer (FRET) imaging (also termed as E-FRET imaging) is a popular fluorescence intensity-based FRET quantification method. Here, an automated E-FRET microscope with user-friendly interfaces was set up for dynamical online quantitative live-cell FRET imaging. This microscope reduces the time of a quantitative E-FRET imaging from 12 to 3 s. After locating cells, calibration of the microscope and E-FRET imaging of the cells can be performed automatically by clicking 'Capture' button on interfaces. E-FRET imaging was performed on the microscope for living cells expressing different FRET tandem constructs. Dynamical E-FRET imaging on the microscope for live cells coexpressing CFP-Bax and YFP-Bax treated by staurosporine (STS) revealed three Bax redistribution stages: Bax translocation from cytosol to mitochondria within 10 min, membrane insertion with conformational change on mitochondrial membrane within about 30 min, and subsequent oligomerisation within about 10 min. Because of excellent user-friendly interface and stability, the automated E-FRET microscope is a convenient tool for quantitative FRET imaging of living cell. LAY DESCRIPTION: Acceptor-sensitised 3-cube fluorescence resonance energy transfer (FRET) imaging (also termed as E-FRET) is a popular fluorescence intensity-based FRET quantification methods. E-FRET measurements are currently performed manually, and a complete FRET measurement takes about 12 s. E-FRET measurement necessitates not only a skilled operator and specialised equipment but also expertise in the interpretation of FRET signals, a considerable challenge in the application of FRET technology in living cells. Furthermore, manual E-FRET microscope is hard to perform dynamical quantitative FRET measurement, the ever-increasing applications in mapping the biochemical signal transduction within cells. Here, an automated E-FRET microscope with user-friendly interfaces was set up for dynamical online quantitative live-cell FRET imaging. This microscope reduces the time of a quantitative E-FRET imaging from 12 to 3 s. After locating cells, calibration of the microscope and E-FRET imaging of the cells can be performed automatically by clicking 'Capture' button on interfaces. Because of excellent user-friendly interface and stability, the automated E-FRET microscope is a convenient tool for quantitative FRET imaging of living cell.

Abstract
OBJECTIVE To establish an apicoectomy guide template design and manufacturing method, based on multi-source data fusion, computer aided design (CAD) and fused deposition modeling (FDM). The feasibility of the guide template was preliminary evaluated by the in vitro model experiment. METHODS An extracted upper anterior tooth, after root canal treatment, was optical scanned, after which the extracted upper anterior tooth was poured in an apicoectomy plaster model. Cone-beam computed tomography (CBCT) scanning of the apicoectomy plaster model was performed, after which optical scanning of the plaster model for apical resection surgery was carried out. All of the relevant CBCT and optical scanning data of the extracted upper anterior tooth and the apicoectomy plaster model were introduced into the Geomagic Studio 2012 software. The multi-source data fusion technology was used to virtually simulate the three-dimensional positional relationship of the extracted tooth, the dentition, the alveolar bone and the gingival, based on which, the three-dimensional design of the apicoectomy guide template was completed in the Geomagic Studio 2012 software. With the technology of fused deposition modeling, the apical resection surgical guide template was three-dimensionally printed with the material of polylactic acid (PLA). Under the guidance of the surgical guide template, the root apical resection was performed on the plaster model. After the apicoectomy, the extracted upper anterior tooth was taken off from the apicoectomy plaster model and then was given the optical scanning. The apical resection length and angle were calculated by the function of distance measurement and angle measurement, and the results were compared with the preset values. RESULTS The length of the apical resection was 2.88 mm along the direction of the long axis of the tooth, which was 0.12 mm lower than the preset 3 mm. The included angle between the apical resection plane and the long axis of the tooth was 77.9°, 12.1° lower than the preset 90°. CONCLUSION This study successfully established a digital design and production method of apicoectomy guide template by combing the multi-source data fusion, CAD and FDM technology. The design route and the production method are feasible. The study will provide a technology and methodology reference for the development of domestic special software for the digital design of apicoectomy guide template.

Abstract
BACKGROUND Preserving the donor's gallbladder during living donor liver transplantation (LDLT) is a better method for liver transplantation surgery, but not enough is known about gallbladder complications after the operation. METHODS We retrospectively investigated postsurgical donor gallbladder complications in clinical LDLT with gallbladder preservation. The feasibility of retaining the gallbladder during liver graft procurement is discussed. Ninety-one donors with retained gallbladder after LDLT with the hepatic left lateral sectionectomy (from June 2013 to October 2015) were retrospectively analyzed. Donors were followed for 12.6 to 40.7 months after surgery (median 26.1 months). Sonography was used to evaluate gallbladder characteristics before and after surgery. RESULTS Gallbladder function had recovered to almost normal 1 month after transplantation. Four donors (4.40%) experienced gallbladder enlargement that resolved after 3 days. Thickening of the gallbladder wall in 31 donors (34.07%) was restored within 2 to 75 days. Biliary sludge appeared in 9 donors (9.89%); 6 of them recovered within 3 to 34 days. Three (3.30%) and 1 donor (1.10%) suffered gallstone and gallbladder polyps, respectively, which persisted until the last follow-up. CONCLUSION The rate of postoperative complications of the gallbladder in donors was relative low. Preserving the gallbladder in liver transplantation donors during liver graft procurement is feasible and safe.

Abstract
Distal tibial fractures with soft tissue damage are relatively difficult to treat. We assessed the outcomes of patients with these fractures treated with the Expert Tibial Nail® (DePuy Synthes, Raynham, MA) from March 2012 to December 2014. At 6 months postoperatively, the general health quality of patients was assessed using operative time, interval to return to work, American Orthopaedic Foot and Ankle Society ankle scale score, pain measured using a visual analog scale, and short-form health outcomes 36-item survey physical functioning and mental health dimension scores. Of 11 cases, 7 (63.6%) were open fractures (3 [27.3%] Gustilo-Anderson type II, 3 [27.3%] type IIIA, and 1 [9.1%] type IIIB) and 4 (36.4%) were closed fractures with Tscherne-Oestern type II tissue damage. Their mean age was 52.2 (range 28 to 66) years. The mean operative time was 83 (range 65 to 105) minutes. The mean follow-up period was 16.3 (range 14 to 18) months. The median short-form 36-item survey scores were 79.1 (range 68.9 to 89.0) for the physical function dimension and 77.0 (range 64.3 to 90.0) for the mental health dimension. The mean postoperative ankle score was 88.6 (range 84 to 94). The mean pain score was 1.6 (range 0 to 4) mm. The mean interval to return to work was 14 (range 11 to 17) months. No patient showed evidence of neurovascular damage, malunion, nonunion, or shortening of the tibia. Taken together, we have confirmed that Expert Tibial Nails can effectively treat distal tibial fractures with soft tissue damage.

Abstract
BACKGROUND The use of pediatric donor liver for pediatric liver transplantation (LT) remains controversial and few studies have focused on pediatric deceased donors. To address this issue, we decided to perform a retrospective research, trying to compare the clinical effects between deceased donor LTs (DDLTs) and living donor LTs (LDLTs). METHODS A retrospective review of pediatric LTs using grafts from deceased donors and living donors from June 2013 to August 2016 was performed. The children were divided into a DDLT group and a LDLT group based on their donor styles. The incidence of early vascular complications (VC), biliary complications, and graft and patient survival rates were observed between the 2 groups. RESULTS There were 217 cases of pediatric LTs performed in our hospital from June 2013 to August 2016 (83 DDLTs and 134 LDLTs). The 1-year cumulative survival rates of grafts and recipients were 89.16% and 91.57% in DDLTs, and 95.47% and 95.52% in LDLTs, respectively (P > .05). The incidence of early VC was lower in LDLTs than that in DDLTs (3.7% vs 19.3%, P < .001). The incidence of HAT in children aged less than 1 year was significantly higher in the DDLT group (P < .001) and can be up to 31.82%. The incidence of biliary complications was similar in the 2 groups (8.4% vs 13.5%, P = .285). CONCLUSIONS Pediatric DDLTs have similar graft and patient survival rates with LDLT. The incidence of early VC was higher in DDLTs, and children aged less than 1 year are at a higher risk of developing HAT.

Abstract
PURPOSE To explore the effects and mechanisms of anti-tumor necrosis factor-α (TNF-α) antibody on insulin resistance (IR) in rats with sepsis-induced stress hyperglycemia. METHODS The sepsis-induced stress hyperglycemic rat model was constructed by cecal ligation and puncture combined with the intraperitoneal injection of lipopolysaccharide. The rats were randomly divided into six groups: normal control (NC) group, surgical rats (Cntl) group, high-dose anti-TNF-α antibody therapy (TNF, 6 mg/kg) group, low-dose anti-TNF-α antibody therapy (Tnf, 3 mg/kg) group, insulin therapy (INS) group, and INS + Tnf group. The blood glucose and serum insulin concentrations were detected, followed by analysis of intraperitoneal glucose tolerance test (IPGTT) and hyperinsulinemic-euglycemic clamp. Finally, the expression levels of phospho-Akt (p-Akt), Akt, p-mTOR, mTOR, nuclear factor-κB (NFκB), I kappa beta kinase (IKKβ), and suppressor of cytokine signaling (SOCS-3) were detected by western blotting. RESULTS There was no significant difference in blood glucose concentrations among these groups, while the serum insulin concentration in TNF and Tnf groups was lower than that in the Cntl group at postoperative 6 h (P < 0.05). IPGTT analysis revealed that blood glucose level was lower in the TNF group than that in the Cntl group (P < 0.05). The glucose infusion rate in the Cntl group was lower than that in the Tnf and TNF groups (P < 0.05). The p-Akt/Akt, p-mTOR/mTOR ratio, and expression levels of NFκB, IKKβ and SOCS-3 were lower in the drug intervention than that in the Cntl group (P < 0.05). CONCLUSIONS Anti-TNF-α antibody could reduce IR by inhibiting AKt/mTOR signaling pathway and the expression levels of NFκB, IKKβ, and SOCS-3 in rats with sepsis-induced stress hyperglycemia.

Abstract
OBJECTIVE The objectives of this study were to analyze the potential correlation between post-liver transplantation survival interval and CD4+ T-cell intracellular ATP (iATP) levels, and to describe the distribution of CD4+ T-cell iATP levels in liver transplant recipients. METHODS This was a retrospective analysis of clinical data of 273 patients who underwent liver transplantation from July 2010 to October 2012 in our center and achieved long-term stable survival. CD4+ T-cell iATP level was detected using Cylex ImmuKnow assay. Post-liver transplantation survival was analyzed. RESULTS CD4+ T-cell iATP level significantly differed among patients with different post-liver transplantation survival intervals. The peak CD4+ T-cell iATP levels typically occurred within the first 3 postoperative months. CONCLUSIONS Post-liver transplantation survival interval is correlated with CD4+ T-cell iATP levels.

Abstract
BACKGROUND Auxiliary liver transplantation is accepted as an effective manner to expand the liver donor pool. A difficult surgical technical challenge of the procedure is hepatic vein reconstruction of the graft. METHODS To resolve this problem, complex techniques are used to perform an innovative outflow tract reconstruction in the world's first cross-auxiliary double-domino donor liver transplantation with two whole liver grafts. The inferior vena cava-sparing hepatectomy technique was applied at harvest in the two domino liver donors. For each donor, the three major hepatic veins (right, middle, and left) were joined together to create one single orifice, but there was no sufficient tissue to perform a direct anastomosis. RESULTS The hepatic vein was reconstructed with the use of a longitudinally opened iliac vein graft from a cadaveric donor to prolong the outflow tract for the piggyback suturing. CONCLUSIONS This new technique might provide an innovative surgical approach for reconstructing the complex outflow tract of domino transplantation.

Abstract
Objective: To investigate natural killer (NK) cell quantities and function in patients with immune thrombocytopenia (ITP) . Methods: A total of 66 ITP patients (34 newly diagnosed and 32 in complete remission) were collected from September 2015 to May 2016 in Tianjin Medical University General Hospital, and 30 healthy volunteers were recruited as controls. The percentages of NK cells and their subsets in peripheral blood, the expression of activating receptor (NKp44), inhibitory receptor (NKG2A) and CD16, perforin and granzyme β were detected by flow cytometry. The correlation between the above parameters and patients' immune status and platelet level were evaluated. Results: (1)The percentage of CD3(-)CD56(+) NK cells in newly diagnosed patients (10.99%±4.89%)and patients in complete remission (9.73%±6.75%) were significantly lower than that in healthy controls (14.67%±7.24%)(P=0.023, 0.003). The percentage of NK cells Bright subset was significantly lower in the newly diagnosed patients(0.48%±0.23%)and those in complete remission (0.41%±0.33%) than in healthy controls(0.64%±0.32%)(P=0.037, 0.002); the percentage of Dim subset was also significantly lower in the newly diagnosed (10.16%±5.02%) and patients in complete remission (8.07%±5.74%) than in healthy controls(14.16%±7.19%) (P=0.009, 0.007). (2)The proportion of Bright subset in total NK cells in new diagnosed ITP patients (6.48%±4.33%) was significantly higher than that in healthy controls (4.21%±2.70%)(P=0.020); the proportion of Dim NK cells subset in new diagnosed ITP patients (93.51%±4.33%) was significantly lower than that in healthy controls(95.79%±2.70%) (P=0.020). (3)The expression of activating receptor NKp44 in new diagnosed ITP patients was significantly lower than that in complete remission group and healthy controls[0.28%(0.95%)vs 0.61%(2.05%), 0.92%(0.90%); P=0.047, 0.048]; the expression of inhibitory receptor NKG2A in new diagnosed ITP patients was significantly higher than that in healthy controls(42.34%±23.86% vs 29.25%±12.83%, P=0.009). The proportion of CD16 was significantly lower in the newly diagnosed patients than in healthy controls(93.51%±4.33%95.79%±2.70%, P=0.020). (4)The expression of perforin in the newly diagnosed ITP patients was significantly lower than that in healthy controls [87.52%(25.29%)vs 91.55%(8.29%), P=0.025]; the expression of granzyme β in ITP patients and controls showed no statistically significant difference. (5)The level of NK cells in ITP patients was negatively correlated with CD3(+) CD8(+) T cells (r=-0.387, P=0.012) and CD5(+) CD19(+) B cells in peripheral blood (r=-0.273, P=0.028), positively correlated with the ratio of CD3(+) CD4(+) /CD3(+) CD8(+) (r=0.358, P=0.028) and peripheral platelet count (r=0.314, P=0.011). Conclusion: Deceased quantities and impaired total NK function, insufficient suppression of autoreactive T and B cells might play a role in the pathogenesis of ITP.

Abstract
OBJECTIVE The aim of this work was to analyze the correlation between immunosuppressive therapy and CD4(+) T-cell intracellular adenosine triphosphate (iATP) levels after liver transplantation and to describe the distribution characteristics of iATP in CD4(+) T cells among liver transplant recipients. METHODS We studied 172 patients who were followed regularly after liver transplantation with long-term stable conditions from July 2010 to October 2012. CD4(+) T-cell iATP levels were detected with the use of the Cylex Immuknow Assay method and analyzed retrospectively according to immunosuppressive therapy protocol. RESULTS There was a significant difference in CD4(+) T-cell iATP level among the recipients receiving different immunosuppressive therapy protocols after liver transplantation. CD4(+) T-cell iATP level in the FK506 group and FK506 + prednisone (Pred) groups was higher than in the FK506 + mycophenolate mofetil (MMF), FK506 + MMF + Pred, and rapamycin (Rapa) groups. CD4(+) T-cell iATP level in patients receiving an MMF protocol was lower than in the group without MMF. CONCLUSIONS There is a relationship between distribution immunosuppressive therapy protocol and CD4(+) T-cell iATP level after liver transplantation. MMF and Rapa lower the CD4(+) T-cell iATP level significantly.

Abstract
Background Ankle joint distraction arthroplasty (AJDA) is an alternative surgical procedure for the management of moderate to severe ankle osteoarthritis. However, the benefit of this procedure and failure relative factors are still in debate. The purpose of the current study was to evaluate the functional outcomes of AJDA in treatment of moderate to severe ankle OA and to evaluate the relative factors correlated with treatment failure. Methods Forty-six van Dijk stages II and III ankle osteoarthritis patients were included. Fifteen males and 31 females with a mean age of 54.8 (range, 42–71) years were followed with a mean of 42.8 (range, 24–68) months. The Ankle Osteoarthritis Scale (AOS) and American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score were used for functional outcome evaluation. The talar tilt (TT) angle and ankle joint space distance (AJSD) were evaluated. The risk ratio (RR) was calculated for each potential failure relative factor. Results The AOS and AOFAS scores were significantly improved at the last follow-up time (P < 0.01). The AJSD was improved in 61% of patients and with a significant improvement compared with the preoperative conditions (P < 0.01). The TT angle and range of motion reached no significant difference. The failure rate was 21.7%. Patients with large TT (≥5°) angle (RR = 3.81, 95% CI 1.28–11.33, P = 0.02) and obesity (RR = 3.58, 95% CI 1.30–9.89, P = 0.01) were found to have positive correlation with failure. No correlation was found between failure and gender, or overweight, or side, or age, or type and stage of OA, or pin infection. Conclusions The current study confirmed the early functional outcomes of ankle distraction arthroplasty. However, this procedure still has a relatively high failure rate, especially for those obese patients and patients with large TT angles.

Abstract
OBJECTIVES Obesity has become a global epidemic and threat to public health. A good understanding of the causes can help attenuate the risk and spread. Environmental pollutants may have contributed to the rising global obesity rates. Some research reported associations between chemical pollutants and obesity, but findings are mixed. This study systematically examined associations between chemical pollutants and obesity in human subjects. METHODS Systematic review of relevant studies published between 1 January 1995 and 1 June 2016 by searching PubMed and MEDLINE®. RESULTS Thirty-five cross-sectional (n = 17) and cohort studies (n = 18) were identified that reported on associations between pollutants and obesity measures. Of them, 16 studies (45.71%) reported a positive association; none reported a sole inverse association; three (8.57%) reported a null association only; six (17.14%) reported both a positive and null association; seven (20.00%) reported a positive and inverse association; and three studies (8.57%) reported all associations (positive, inverse and null). Most studies examined the association between multiple different pollutants, different levels of concentration and in subsamples, which results in mixed results. Thirty-three studies reported at least one positive association between obesity and chemicals, such as polychlorinated biphenyls, biphenyl A, dichlorodiphenyltrichloroethane, dichlorodiphenyldichloroethylene and more. Certain chemicals, such as biphenyl A, were more likely to have high ORs ranging from 1.0 to 3.0, whereas highly chlorinated polychlorinated biphenyls were more likely to have negative ORs. Effects of chemicals on the endocrine system and obesity might vary by substance, exposure level, measure of adiposity and subject characteristics (e.g. sex and age). CONCLUSIONS Accumulated evidences show positive associations between pollutants and obesity in humans. Future large, long-term, follow-up studies are needed to assess impact of chemical pollutants on obesity risk and related mechanisms.

Abstract
BACKGROUND This study aimed to investigate the clinical feasibility of treating severe open Lisfranc injuries by means of one-stage internal fixation with k-wires associated with vacuum sealing drainage (VSD). METHODS The clinical outcomes of 20 cases of severe open Lisfranc joint fracture-dislocation treated by using one-stage internal fixation with k-wires associated with VSD, after debridement and suturing during emergency treatment, were reviewed. RESULTS At 6 and 12 months after surgery, the American Orthopaedic Foot and Ankle Society midfoot scores were 69.2 and 78.2, the positive rates were 75 and 85 %, and the average visual analogue scale scores were 4.3 and 1.3, respectively. The average time of internal fixation surgery was 47 min (30-70 min). There were three cases of wound-edge necrosis; however, there were no cases of skin necrosis around the incision, or deep infection. The mean time of first hospital stay was 16.1 days (10-23 days). CONCLUSIONS Treatment of severe open Lisfranc fracture and dislocation through one-stage internal fixation with k-wires in association with VSD led to fast anatomical reduction, stabilized bony structure, fast soft tissue recovery, and good short-term follow-up results.

Abstract
OBJECTIVE This study was conducted to analyze the clinical characteristics and outcome of measles in pediatric liver transplant recipients. METHODS This study includes a retrospective data analysis of five pediatric liver transplant recipients with measles who were treated at the Liver Transplant Section, Beijing Friendship Hospital, China, from March to April 2014. RESULTS The clinical manifestations of measles in pediatric liver transplant recipients were serious. There were three cases complicated with pneumonia, and one with laryngitis. Two cases presented with severe measles pneumonia that developed into severe respiratory failure requiring mechanical ventilation. Four patients recovered after treatment and one patient died of respiratory failure. CONCLUSION Pediatric liver transplant recipients with measles are at high risk of severe pneumonia. Measles pneumonitis is frequently fatal to immunocompromised pediatric patients. Treatment should be initiated as soon as possible.

Abstract
OBJECTIVE To discuss rules of anatomic shifting of the porta hepatis structures of the original graft and dissection techniques for the portal vein (pull-out technique) in pediatric liver re-transplantation. METHOD We summarized four cases of paediatric liver re-transplantation. The main donor type is partial liver graft especially using the left lateral lobe. RESULT In paediatric liver re-transplantation, gross morphological changes were observed in the liver, and the spatial position of the porta hepatis structures was shifted clockwise (with the anastomosis of the hepatic vein as the origin). Preoperative three-dimensional imaging showed that segment 3 of the liver graft increased in a compensatory manner. The pull-out technique could expose the surgical field without dissection and separation, and reduce the technical difficulty of identifying and dissociating the anatomical structures. CONCLUSION Changes in the spatial location and structure of the liver portal anatomy increase the difficulties and risks of surgery. We can reduce the difficulty of surgical anatomy, and the risk of bleeding and injury and increase the safety of paediatric liver re-transplantation by evaluation and the application of special techniques.

Abstract
Management of type C pilon fractures remains controversial and challenging. The aim of the present study was to provide a 2-stage protocol with vacuum sealing drainage for the treatment of type C pilon fractures. From March 2009 to March 2012, 16 patients (mean age 42.3 years) were admitted to our department with type C pilon fractures and treated with single-stage external fixation and second-stage internal fixation (anteromedial incision) combined with vacuum sealing drainage. The American Orthopaedic Foot and Ankle Society scale score averaged 86.5 for this group of patients. The range of motion was 30° ± 8.9°. An excellent or good American Orthopaedic Foot and Ankle Society scale score was obtained for all patients. None of the 16 patients developed skin necrosis, nonunion, or fixation failure during the follow-up period. Moreover, the visual analog scale pain scores were 0.7 ± 0.8, 0.9 ± 0.7, and 1.4 ± 1.0 during rest, active movement, and weightbearing, respectively. The postoperative radiographs showed excellent treatment effects. A 2-stage protocol, combined with vacuum sealing drainage, for the treatment of type C pilon fractures can eliminate deep infection and complex surgery and is a simple and effective treatment method. In addition, full exposure of the anteromedial incision, the avoidance of the anterior tibial muscle tendon sheath, and the avoidance of soft tissue injuries are generally recommended in this operation.

Abstract
OBJECTIVE The posterolateral window is a suitable position for screw insertion. The aim of this study was to define this position for posterolateral screw insertion. METHODS Fifteen adult cadaver ankles were used in this study. When the ankle was positioned in a neutral position, the posterolateral window was exposed. Height and width of the window were measured. Vertical distance from the center of the window to the lateral malleolus tip (LMT), horizontal distance from the center of the window to the lateral of the Achilles tendon (LAT), and horizontal distance from the lateral of the Achilles tendon to the sural nerve (SN) were measured. Additionally, the anatomical relationships between the center of the window (the screw insertion point) and surrounding tissues were noted. RESULTS The results indicated that the posterolateral window was bounded medially by the lateral tubercle of the posterior process of the talus (LTPT), laterally by the posterior border of lateral malleolar (PBLM), superiorly by the trochlear articular surface (TAS), and inferiorly by the posterior calcaneal facet (PCF). The height and width of the posterolateral window were 1.89±0.04 cm and 0.91±0.01 cm, respectively. LMT was 0.40±0.01 cm, LAT was 0.19±0.02 cm, and SN was 0.62±0.04 cm. The present data showed that posterior screw insertion may be a safer screw insertion technique for talar neck fractures. Performing the operation through the posterolateral window had no negative effect on surrounding tissues such as the flexor hallucis longus and posterior talofibular ligament tissues when the ankle joint was positioned in a neutral position. Additionally, the screw head should be countersunk to reduce intraoperative risk. CONCLUSION The posterolateral window is a safer point for posterolateral screw insertion for talar neck fractures.

Abstract
OBJECTIVE The aim of this study was to facilitate the systematic discovery of diagnostic biomarkers of diabetic nephropathy (DN). METHODS 3 publicly available independent cohorts were got from Gene Expression Omnibus database. Gene expression array were used to screen for genome-wide relative significance (GWRS) and genome-wide global significance (GWGS). The most significant up- and down-regulated top 100 gene signatures were identified using a fold change based model. Then the protein-protein interaction (PPI) network was constructed, while the hub genes in this PPI network were identified by centrality analysis. Modules detection was performed to explore the functions of the modules. Meanwhile, gene enrichment analysis was performed to illuminate the biological pathways and processes associated with DN. RESULTS The most significant up- and down-regulated top 100 gene signatures were identified and a PPI network was established. Several hub genes (VEGFA, IL8, MYC, CD14, ALB) were discovered. Several functional modules were revealed. Biological pathways including cytokine-cytokine receptor interaction and p53 signaling pathway, and processes including inflammatory response, response to wounding and enzyme linked receptor protein signaling pathway were identified. CONCLUSION Our study displayed underlying biomarkers including biological pathways and several hub genes of DN.

Abstract
The culprit of hepatic fibrosis (HF) is linked to suprathreshold deposition of collagen. Thus, collagen reduction by improved metabolism contributes to HF management. In this study, we aimed to investigate the hepatoprotective effects of Danshensu (DSS) against carbon tetrachloride (CCl4)-induced HF rats. The results showed that DSS-administrated rats resulted in decreasing in hepatosomatic indexes, and lowering serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Meanwhile, the activities of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) were increased, while the content of malonaldehyde (MDA) was lessened in liver tissue of DSS administration group. In addition, the pro-fibrotic markers of hydroxyproline (Hyp), type III procollagen (PCIII) and hyaluronic acid (HA) contents were decreased. Histopathological examination confirmed that the hepatotoxicity in CCl4-injured rats was alleviated following the DSS administration. Furthermore, intrahepatic protein expressions of alpha-smooth muscle actin (α-SMA), phosphorylated JAK2 (p-JAK2) and phosphorylated STAT3 (p-STAT3) were effectively down-regulated, respectively. Overall, this work demonstrates that DSS played the protective effect against CCl4-induced cytotoxicity in liver tissue, which the probable mechanism is associated with attenuation of lipid peroxidation, collagen accumulation and enhancement of anti-oxidative defense capability, as well as regulation of intrahepatic JAK/STAT pathway for maintaining collagenic homoeostasis.

Abstract
Background: Glutathione S-transferase 1 (GSTP1) inactivation is associated with CpG island promoter hypermethylation in the majority of prostate cancers (PCs). This study assessed whether the level of circulating methylated GSTP1 (mGSTP1) in plasma DNA is associated with chemotherapy response and overall survival (OS). Methods: Plasma samples were collected prospectively from a Phase I exploratory cohort of 75 men with castrate-resistant PC (CRPC) and a Phase II independent validation cohort (n=51). mGSTP1 levels in free DNA were measured using a sensitive methylation-specific PCR assay. Results: The Phase I cohort identified that detectable baseline mGSTP1 DNA was associated with poorer OS (HR, 4.2 95% CI 2.1–8.2; P<0.0001). A decrease in mGSTP1 DNA levels after cycle 1 was associated with a PSA response (P=0.008). In the Phase II cohort, baseline mGSTP1 DNA was a stronger predictor of OS than PSA change after 3 months (P=0.02). Undetectable plasma mGSTP1 after one cycle of chemotherapy was associated with PSA response (P=0.007). Conclusions: We identified plasma mGSTP1 DNA as a potential prognostic marker in men with CRPC as well as a potential surrogate therapeutic efficacy marker for chemotherapy and corroborated these findings in an independent Phase II cohort. Prospective Phase III assessment of mGSTP1 levels in plasma DNA is now warranted.
