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
Sleep fragmentation (SF), which refers to discontinuous and fragmented sleep, induces cognitive impairment and anxiety-like behavior in mice. However, whether SF can affect motor capability in healthy young wild-type mice and the underlying mechanisms remain unknown. We performed seven days of sleep fragmentation (SF 7d) interventions in young wild-type male mice. While SF mice experienced regular sleep disruption between Zeitgeber time (ZT) 0-12, control mice were allowed to have natural sleep (NS) cycles. Homecage analysis and conventional behavioral tests were conducted to assess the behavioral alterations in behavioral patterns in general and motor-related behaviors. Sleep structures and the power spectrum of electroencephalograms (EEGs) were compared between SF 7d and NS groups. Neuronal activation was measured using c-Fos immunostaining and quantified in multiple brain regions. SF of 7 days significantly decreased bouts of rearing and sniffing and the duration of rearing and impaired motor coordination. An increase in the total sleep time and a decrease in wakefulness between ZT12-24 was found in SF 7d mice. In SF 7d mice, EEG beta1 power was increased in rapid eye movement (REM) sleep while theta power was decreased during wakefulness. SF 7d resulted in significant suppression in c-Fos (+) cell counts in the motor cortex and hippocampus but an increase in c-Fos (+) cell counts in the substantia nigra pars compacta (SNc). In summary, SF 7d suppressed explorative behaviors and impaired motor coordination as compared to NS. EEG power and altered neuronal activity detected by c-Fos staining might contribute to the behavioral changes.

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
BACKGROUND Emerging evidence has uncovered a vital role of nucleus accumbens (NAc) neurons that express the dopamine D1 receptor (D1R) and its upstream neural circuit in general anesthesia (GA) regulation. However, the underlying downstream neural basis of the modulation of GA emergence by NAc D1R neurons remains unknown. In the present study, we explored the downstream neural mechanism of NAc D1R neurons in the modulation of emergence from sevoflurane GA. METHODS We traced the axonal projections of NAc D1R neurons using a cell type-specific anterograde tracing method and immunohistochemical techniques in D1R-Cre mice. Optogenetic stimulations combined with electroencephalogram/electromyogram recordings and behavioral tests were used to determine the effects of optogenetic activation of the axonal terminals of NAc D1R neurons on sevoflurane emergence during sevoflurane-induced continuous, steady-state general anesthesia (CSSGA) or burst-suppression oscillations. RESULTS Labeled efferent fibers of NAc D1R neurons were highly distributed in the ventral pallidum (VP), lateral hypothalamus (LH), and substantia nigra pars compacta. Optogenetic activation of the NAc D1R -VP circuit during CSSGA with sevoflurane induced cortical activation (mean ± standard deviation [SD]; delta power: prestimulation versus during stimulation, 48.7% ± 5.7% vs 35.1% ± 3.3%, P < .0001; beta power: 7.1% ± 2.7% vs 14.2% ± 3.3%, P = .0264) and behavioral emergence, and restored the righting reflex in 66.7% of ChR2 mice. Optogenetic stimulation of the NAc D1R -LH circuit also produced cortical activation (delta power: prestimulation versus during stimulation, 45.0% ± 6.5% vs 36.1% ± 4.6%, P = .0016) and behavioral emergence, and restored the righting reflex in 100% of the ChR2 mice during CSSGA with sevoflurane. Under a sevoflurane-induced burst-suppression state, NAc D1R -VP/LH circuit activation produced evidence of cortical activation (burst-suppression ratio [BSR]: NAc D1R -VP circuit, prestimulation versus during stimulation, 42.4% ± 4.0% vs 26.3% ± 6.0%, P = .0120; prestimulation versus poststimulation, 42.4% ± 4.0% vs 5.9% ± 5.6%, P = .0002; BSR: NAc D1R -LH circuit, prestimulation versus during stimulation, 33.3% ± 13.4% vs 5.1% ± 4.9%, P = .0177; prestimulation vs poststimulation, 33.3% ± 13.4% vs 3.2% ± 4.0%, P = .0105) and behavioral emergence. CONCLUSIONS Both NAc D1R -VP and NAc D1R -LH circuits are sufficient to promote reanimation from sevoflurane GA by simultaneously inducing cortical and behavioral emergence.

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
Sleep disturbance is common in patients with cancer and is associated with poor prognosis. However, the effects of sleep deprivation (SD) on immune surveillance during the development of hepatocellular carcinoma (HC) and the underlying mechanisms are not known. This was investigated in the present study using mouse models of SD and tumorigenesis. We determined that acute and chronic sleep deprivation (CSD) altered the relative proportions of various immune cell types in blood and peripheral organs. CSD increased tumor volume and weight, an effect that was enhanced with increasing CSD time. Expression of the cell proliferation marker Ki-67 was elevated in tumor tissues, and tumor cell infiltration into adjacent muscles was enhanced by CSD. Multicolor flow cytometry analysis revealed that CSD significantly reduced the numbers of antitumor CD3+ T cells and natural killer (NK) cells and increased that of immunosuppressive CD11b+ cells infiltrating into the tumor microenvironment from the spleen via the peripheral blood. These results indicate that CSD impairs immune surveillance mechanisms and promotes immunosuppression in the tumor microenvironment to accelerate tumor growth, underscoring the importance of alleviating sleep disturbance in HC patients in order to prevent HC progression.

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
Vestibular nuclei complex (VN) glutamatergic neurons play a critical role in the multisensory and multimodal processing. The dysfunction of VN leads to a series of vestibular concurrent symptoms, such as disequilibrium, spatial disorientation, autonomic disorders and even emotion disorders. However, the reciprocal neural connectivity in the whole brain of VN glutamatergic neurons was incompletely understood. Here, we employed a cell-type-specific, cre-dependent, modified virus vector to retrogradely and anterogradely trace VN glutamatergic neurons in the VGLUT2-IRES-Cre mouse line. We identified and analyzed statistically the afferents and efferents of VN glutamatergic neurons in the whole brain, and also reconstructed monosynaptic inputs distribution of VN glutamatergic neurons at the three-dimensional level with the combination of a fluorescence micro-optical sectioning tomography system (fMOST). We found that VN glutamatergic neurons primarily received afferents from 57 nuclei and send efferents to 59 nuclei in the whole brain, intensively located in the brainstem and cerebellum. Projections from nuclei in the cerebellum targeting VN glutamatergic neurons mainly performed the balance control - the principal function of the vestibular system. In addition, VN glutamatergic neurons sent projections to oculomotor nucleus, trochlear nucleus and abducens nucleus dominating the eye movement. Except for the maintenance of balance, VN glutamatergic neurons were also directly connected with other functional regions, such as sleep-wake state (locus coeruleus, dorsal raphe nucleus, and laterodorsal tegmental nucleus, gigantocellular reticular nucleus, lateral paragigantocellular nucleus, periaqueductal gray, subcoeruleus nucleus, parvicellular reticular nucleus, paramedian raphe nucleus), and emotional regulation (locus coeruleus and dorsal raphe nucleus). Hence, this study revealed a comprehensive whole-brain neural connectivity of VN glutamatergic neurons and provided with a neuroanatomic foundation to further study on central vestibular circuits.

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
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.

Abstract
Honokiol (HNK) is a small-molecule lignin extracted from Magnolia Officinalis, demonstrating high potency in promoting nonrapid eye movement (NREM) sleep by modulating the benzodiazepine site of the GABAA receptor. However, the clinical use of HNK in the treatment of insomnia is restricted by its extremely low oral bioavailability. In the present work, enhanced oral bioavailability of HNK was achieved by loading it into poly lactide-glycolide acid microparticles (HNK-MP). After oral administration, HNK-MP demonstrated 15-fold increase of AUC0-12 h in comparison to free HNK. The maximum blood concentration ( Cmax) of HNK in HNK-MP-treated rats was 3.6 μg/mL at 2 h after oral administration, which was 6.5-fold of that in free HNK-treated rats. Oral administration of HNK-MP (20 mg/kg) efficiently increased NREM sleep by 60% by enhancing the transition from wakefulness to NREM sleep in rats. The biosafety of HNK-MP was assessed in vivo, and no damage occurred in the gastrointestinal tract. The present study provides a promising oral HNK formulation for the treatment of insomnia.

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
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
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
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
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
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.

Abstract
Cancerous inhibitor of protein phosphatase 2A (CIP2A) is a recently identified human oncoprotein that can stabilize some proteins by inhibiting degradation mediated by protein phosphatase 2A (PP2A) and it increases the proliferation of several cancer cells. Recent studies have highlighted a potential role for CIP2A in promoting tumor progression and metastasis. However, whether CIP2A could increase chemoresistance of cancer cells to chemotherapeutic agent cisplatin remains unclear. To determine whether CIP2A serves as a potential therapeutic target of human non-small-cell lung cancer (NSCLC), we utilized small interference RNA (siRNA) to knock down CIP2A expression in human NSCLC cells and analyzed their phenotypic changes. The data demonstrated that CIP2A silencing led to decreased proliferation, impaired clonogenicity and enhanced chemosensitivity and apoptosis to cisplatin in human NSCLC cells, as well as reduced Akt phosphorylation. In addition, overexpression of CIP2A diminished NSCLC cell chemosensitivity to cisplatin by inducing activation of Akt pathway, suggesting critical roles of CIP2A in NSCLC cell chemoresistance to cisplatin and rasing the possibility of CIP2A inhibition as a promising approach for lung cancer therapy.

Abstract
Fas/FasL protein expression of bone marrow hematopoietic cells was investigated in severe aplastic anemia (SAA) patients. Fas expression was evaluated in CD34(+), GlycoA(+), CD33(+), and CD14(+) cells labeled with monoclonal antibodies in newly diagnosed and remission SAA patients along with normal controls. FasL expression was evaluated in CD8(+) cells in the same manner. In CD34(+) cells, Fas expression was significantly higher in the newly diagnosed SAA group (46.59 ± 27.60%) than the remission (6.12 ± 3.35%; P < 0.01) and control (8.89 ± 7.28%; P < 0.01) groups. In CD14(+), CD33(+), and GlycoA(+) cells, Fas levels were significantly lower in the newly diagnosed SAA group (29.29 ± 9.23, 46.88 ± 14.30, and 15.15 ± 9.26%, respectively) than in the remission (47.23 ± 31.56, 67.22 ± 34.68, and 43.56 ± 26.85%, respectively; P < 0.05) and normal control (51.25 ± 38.36, 72.06 ± 39.88, 50.38 ± 39.88%, respectively; P < 0.05) groups. FasL expression of CD8(+) cells was significantly higher in the newly diagnosed SAA group (89.53 ± 45.68%) than the remission (56.39 ± 27.94%; P < 0.01) and control (48.63 ± 27.38%; P <0.01) groups. No significant differences were observed between the remission and control groups. FasL expression in CD8(+) T cells was significantly higher in newly diagnosed patients, and CD34(+), CD33(+), CD14(+), and GlycoA(+) cells all showed Fas antigen expression. The Fas/FasL pathway might play an important role in excessive hematopoietic cell apoptosis in SAA bone marrow. Furthermore, CD34(+) cells are likely the main targets of SAA immune injury.

Abstract
The purpose of this study is to enhance the dissolution rate of prednisone by co-grinding with Neusilin to form a complex that can be incorporated into a mini-tablet formulation for pediatrics. Prednisone-Neusilin complex was co-grinded at various ratios (1:1, 1:3, 1:5, and 1:7). The physicochemical properties of the complex were characterized by various analytical techniques including: differential scanning calorimetry (DSC), X-ray powder diffraction (XRPD), scanning electron microscope (SEM), particle size, surface area, solubility, and dissolution rate. The co-grinded prednisone-Neusilin complex (1:7) was blended with other excipients and was formulated into a 2-mm diameter mini-tablet. The mini-tablets were further evaluated for thickness, weight, content uniformity, and dissolution rate. To improve taste masking and stability, mini-tablets were coated by dip coating with Eudragit® EPO solution. DSC and XRPD results showed that prednisone was transformed from crystalline state into amorphous state after co-grinding with Neusilin. Particle size, surface area, and SEM results confirmed that prednisone was adsorbed to Neusilin's surface. Co-grinded prednisone-Neusilin complex (1:7) had a solubility of 0.24 mg/mL and 90% dissolved within 20 min as compared to crystalline prednisone which had a solubility of 0.117 mg/mL and 30% dissolved within 20 min. The mini-tablets containing co-grinded prednisone-Neusilin complex (1:7) exhibited acceptable physicochemical and mechanical properties including dissolution rate enhancement. These mini-tablets were successfully dip coated in Eudragit® EPO solution to mask the taste of the drug during swallowing. This work illustrates the potential use of co-grinded prednisone-Neusilin to enhance solubility and dissolution rate as well as incorporation into a mini-tablet formulation for pediatric use.

Abstract
The aim of the paper is to determine the incidence of celiac artery compression (CAC) based on computed tomography (CT) scan and correlate the findings to the clinical presentation of patients presenting for CT scan in a hospital. Abdominal CT scans of patients were reviewed between September 2010 and November 2010. CAC was diagnosed if the celiac axis appeared to have a hook or U-shaped appearance with stenosis. The medical records of the patients were reviewed for gastrointestinal symptoms (abdominal pain, nausea, vomiting, constipation, diarrhea), as well as food fear and weight loss. Patients with CAC had lower incidence of symptoms compared with those without CAC (42.1 versus 65.3%, P = 0.042). A total of 450 patients were evaluated. In the end, 284 had both complete medical records and CT scans. The mean age for all patients was 51.3 ± 1.2 years. There were 124 men (42.6%) and 160 (57.4%) women. Nineteen (6.7%) patients had radiological evidence of CAC. CAC is not an uncommon CT finding in patients presenting for CT scan.

Abstract
OBJECTIVES We aimed to evaluate the relationships between primary tumour, maximum standardised uptake value, metabolic tumour volume and seventh edition American Joint Committee on Cancer (AJCC) classification in oesophageal squamous cell carcinoma (OSCC) patients. METHODS Fluorine-18 fludeoxyglucose ((18)F-FDG) positron emission tomography (PET)-CT scans of 41 consecutive newly diagnosed OSCC patients were retrospectively reviewed. Maximum standard uptake value (SUV(max)) and metabolic tumour volume (MTV) were recorded. Two-tailed Spearman's correlation was used to analyse the relationships between the metabolic parameters and the AJCC staging system. RESULTS Positive correlations were observed between SUV(max), MTV and tumour (T) stage, in addition to node (N) stage and AJCC stage. Both metabolic parameters were independent variables that significantly affected the N stage and AJCC stage, and SUV(max) was the only independent variable that significantly affected the T stage. CONCLUSION The metabolic parameters derived from (18)F-FDG PET-CT were positively correlated with T, N and AJCC stage in primary OSCC. Our findings may suggest a complementary role of these parameters to seventh-edition AJCC staging in the prognostication of OSCC patients.

Abstract
HYPOTHESIS The goal of the present study was to compare minimally invasive percutaneous plate osteosynthesis (MIPPO) technique and conventional open reduction with LCP for the treatment of clavicle midshaft fractures in adults in a randomized, controlled, clinical trial with a minimum of 1-year follow-up. MATERIALS AND METHODS Between June 2006 and May 2008, 64 cases of open reduction and internal plate fixation were performed for clavicle midshaft fractures. The operative indications were complete displacement, severe comminution and marked shortening of the clavicle (>2cm). MIPPO and conventional open reduction surgery procedures with LCP were used in 32 and 32 cases, respectively. RESULTS The mean time to union was 13 weeks in the open reduction group compared to 12 weeks in MIPPO group (P>0.05). The MIPPO group had no significantly superior Constant shoulder scores or DASH scores at all time-points (P>0.05). However, the complications in the open reduction group were dysesthesia in the area of the incision and directly below in 10 cases, hypertrophic scarring in five cases, painful shoulder in two cases and a limitation of shoulder motion in one case (P>0.05). The complications in the MIPPO group were dysesthesia in two cases, no hypertrophic scarring, no painful shoulder, no limitation of shoulder motion were noted (P<0.05). Patients in this operative group were more satisfied with cosmetic appearance and overall outcome than those in the conventional open reduction group. CONCLUSIONS Operative treatment with a LCP for clavicle shaft fractures can be used to obtain stable fixation. Particularly, MIPPO of displaced midshaft clavicular fractures resulted in a lower rate of dysesthesia, hypertrophic scarring, and a better cosmetic than conventional open reduction, although the functional outcomes (Constant and DASH) were no different between the two groups. Overall satisfaction was higher in the MIPPO group than conventional open reduction group. LEVEL OF EVIDENCE Level IV. Retrospective study.
