Objective: To investigate the clinical results of arthroscopic double-pulley double row suture technique for the treatment of bigger Ideberg Ia glenoid fracture. Methods: From January 2014 to July 2017, data of patients with Ideberg Ia glenoid fracture who were treated by arthroscopic double-pulley double row suture technique were retrospectively analyzed. Totally 24 patients were enrolled of whom 13 were males and 11 were females. The mean age was 50.14±10.60 years (range, 34-67). In those patients, there were 8 cases of glenoid fracture alone, 4 cases of glenoid fracture associated with greater tuberosity fracture, 5 cases of glenoid fracture with rotator cuff tear, 4 cases of glenoid fracture with shoulder anterior dislocation and greater tuberosity fracture, 2 cases of glenoid fracture with shoulder anterior dislocation and rotator cuff tear, and 1 case of shoulder anterior dislocation with ipsilateral distal radius fracture. The fragment accounts for 28.91±5.35% (range, 25.1%-38.5%) of the glenoid articular surface. According to the size of the fragment, one medial row anchor was used to implant at the medial edge of the fracture bed of the anterior edge of the glenoid; two to four lateral row suture anchors were used to implant at the margin of the glenoid joint surface sequentially from low level to higher level, and simplified double-pulley technique was finally used to fix the fragment. The situation of fracture reduction and healing and the post-operative complications were evaluated. The Constant-Murley, DASH and VAS were also recorded. Results: Satisfactory fracture reduction and fixation were achieved in all 24 patients. The mean follow-up time was 19.5 months (range, 12-36). Mean VAS was 0.8±0.8 (range, 0-2). The range of motion at the latest follow-up was: anterior flexion 145°-180° (mean, 161.00°±5.77°), external rotation at the side 35°-60° (mean, 46.43°±6.63°), internal rotation L₃-T₁₀ level. The mean Constant-Murley score was 88.1±3.7 (range, 81-93), and mean DASH score was 8.4±4.7 (range, 0-40.4). All cases except one showed no dislocation or disability of the shoulder. The CT scans showed: 19 cases of which the step-off of articular surface was less than 2 mm; 4 cases of which the step-off was between 2 mm to 4 mm and 1 case of which the step-off was more than 4 mm. No severe osteoarthritis was identified at the latest follow-up, and only 1 patient at the age of 67 showed slight osteoarthritis. Two patients with shoulder anterior dislocation and rotator cuff tear committed significant restricted shoulder range of motion. Conclusion The arthroscopic simplified double-pulley double row suture technique was identified safe, effective and reliable for treating the bigger Ideberg Ia glenoid fracture. The technique is able to provide clear visulization of the fracture and achieve excellent clinical results.

Objectives To study the clinical characteristics,diagnosis,treatment and prognosis of cancer metastases to the thyroid gland.Methods At Tianjin Medical University Cancer Hospital,from 1980 to 2016 30 patients were identified with a metastatic malignant tumor of the thyroid gland.Results Primary tumor sites were in the esophagus (26.7％),lung (16.7％),and kidney (13.3％).The median age at discovery of thyroid metastasis was 56 years old.The time lapse ranged from 0 to 108 months.There were 18 patients with metachronous metastasis with median survival of 36 months,12 patients were with synchronous metastasis,and the median survival was 8 months (P ＜ 0.01).20 patients were treated with thyroid surgery,and of which 15 patients were given post-op radiotherapy and chemotherapy.Patients who underwent thyroid resection had a median survival of 15 months,while that was 8 months in those without thyoid surgery (P ＜ 0.01).Conclusions Metastases to the thyroid gland is a rare clinical phenomenon,the prognosis of patients is mainly related to the biological behavior of primary tumors,but surgical resection and combined treatment can increase the survival rate.

And chimerism is essential for inducing immune tolerance .

The mammalian central nervous system (CNS) is considered an immune privileged system as it is separated from the periphery by the blood brain barrier (BBB). Yet, immune functions have been postulated to heavily influence the functional state of the CNS, especially after injury or during neurodegeneration. There is controversy regarding whether adaptive immune responses are beneficial or detrimental to CNS injury repair. In this study, we utilized immunocompromised SCID mice and subjected them to spinal cord injury (SCI). We analyzed motor function, electrophysiology, histochemistry, and performed unbiased RNA-sequencing. SCID mice displayed improved CNS functional recovery compared to WT mice after SCI. Weighted gene-coexpression network analysis (WGCNA) of spinal cord transcriptomes revealed that SCID mice had reduced expression of immune function-related genes and heightened expression of neural transmission-related genes after SCI, which was confirmed by immunohistochemical analysis and was consistent with better functional recovery. Transcriptomic analyses also indicated heightened expression of neurotransmission-related genes before injury in SCID mice, suggesting that a steady state of immune-deficiency potentially led to CNS hyper-connectivity. Consequently, SCID mice without injury demonstrated worse performance in Morris water maze test. Taken together, not only reduced inflammation after injury but also dampened steady-state immune function without injury heightened the neurotransmission program, resulting in better or worse behavioral outcomes respectively. This study revealed the intricate relationship between immune and nervous systems, raising the possibility for therapeutic manipulation of neural function via immune modulation.

OBJECTIVE: To investigate the hemodynamic effect of Shen-Fu Injection (, SFI) in early volume resuscitation treated septic shock patients by monitoring pulse indicator continuous cardiac output (PICCO). METHODS: All septic shock patients admitted in the Intensive Care Unit of the Affiliated Hospital of Shandong University of Traditional Chinese Medicine from January 1st, 2014 to December 31th, 2015, were reviewed, and totally 65 were enrolled in this study. They were assigned to SFI group (33 cases) and control group (32 cases). All 65 patients underwent conventional treatment mainly including volume resuscitation, antibiotics and vasoactive drugs therapy. The patients of the SFI group received additional 100 mL of SFI intravenously every 12 h. In all 65 patients, the PICCO arterial catheter and vein catheter were implanted within 1 h after the diagnosis of septic shock. In the course of early volume resuscitation, hemodynamic data of patients were recorded by PICCO monitor at 0, 12, and 24 h after the catheter implantation. RESULTS: The hemodynamic indices of the two groups showed no significant differences at the beginning of 0 h (P>0.05). At 12 and 24 h, the hemodynamic indices of SFI group were significantly improved in comparison with the control group (P<0.05), including cardiac index (CI), global end diastolic volume index (GEDI), mean arterial pressure (MAP) and heart rate (HR). In addition, there was no significant change of extra-vascular lung water index between the two groups (P>0.05). CONCLUSION SFI significantly improved hemodynamic indices such as CI, GEDI, MAP and HR in early volume resuscitation treated septic shock patients.

SATB1 plays a crucial role in the invasion and metastasis of breast cancer,and inhibition of SATB1 expression can effectively control breast cancer metastasis. In this study,homogeneous polysaccharides were isolated from Poria cocos and their sulfated derivatives were prepared to screen out the polysaccharide compositions with inhibitory effects on SATB1 expression. Smal-molecule components were removed from P. cocos by ethanol extraction,and P. cocos crude polysaccharide PPS was obtained by water extraction and ethanol precipitation. Then PPS was successively separated by DEAE Sepharose fast flow anion-exchange and Superdex-75 gel permeation chromatographic steps to give PPSW-1. The structure of PPSW-1 was identified and its sulfated derivatives were prepared. Then their inhibitory effects on human breast cancer MDA-MB-231 cells were investigated. A kind of polysaccharide,PPSW-1 with inhibitory effect on human breast cancer MDA-MB-231 cells,was obtained from P. cocos,with a relative molecular weight of 3. 06×104,and structure of 1,6-branched 1,3-α-D-galactan. PPSW-1 and its sulfated derivative Sul-W-1 showed good inhibitory effect on cells migration,and the water solubility of Sul-W-1 was better than that of PPSW-1. In addition,it was found that polysaccharide of P. cocos and its sulfated derivative can inhibit expression of SATB1. In this study,a kind of homogeneous polysaccharide with inhibitory effect on human breast cancer MDA-MB-231 cells was isolated from P. cocos,and its sulfated derivative with similar efficacy but better solubility was prepared,laying the foundation for the substance basis study of P. cocos.

OBJECTIVE: To follow up the participants of the randomized clinical trial "Efficacy and Safety of Niaoduqing Particles () for Delaying Moderate-to-Severe Renal Dysfunction", and assess the long-term effects of Niaoduqing Particles on delaying the progression of renal dysfunction. METHODS: Participants, who had previously been randomly assigned to receive Niaoduqing Particles or placebo for 24 weeks (146 cases in each group), were invited to follow-up and all were administered Niaoduqing Particles 5 g thrice daily and 10 g before bedtime for 24 weeks. The primary endpoints were changes in baseline serum creatinine (Scr) and estimated glomerular filtration rate (eGFR) after completion of the open-label treatment period. RESULTS: After the double-blind period, the median (interquartile range) changes in Scr were 1.1 (-13.0-24.1) and 11.7 (-2.6-42.9) μmol/L for the Niaoduqing Particle and placebo groups, respectively (P=0.008), and the median changes in eGFRs were-0.2 (-4.3-2.7) and-2.21 (-5.7-0.8) mL•min•1.73 m, respectively (P=0.016). There were significant differences in the double-blind period changes in renal function between groups. After the open-label period, the median changes in Scr were 9.0 (-10.0-41.9) and 17.5 (-6.0-50.0) μmol/L for the Niaoduqing Particle and placebo groups according to baseline grouping, respectively (P=0.214), and the median changes in eGFRs were-2.3 (-6.4-1.9) and-3.7 (-7.5-1.1) mL•min•1.73 m, respectively (P=0.134). There were no statistical differences in the open-label period changes in renal function between groups. The eGFR reduction of participants who accepted Niaoduqing Particle treatment for 48 weeks was projected to 2.5 mL•min•1.73 m per year. CONCLUSION Niaoduqing Particles appear to have long-term efficacy for patients with moderate-to-severe renal dysfunction. Although there was no statistical difference, the early use of Niaoduqing Paticles seems to ameliorate the worsening of renal function. (Trial registration No. ChiCTR-TRC-12002448).

About 15%-20% of drug-induced liver injury (DILI) will progress to chronic manifestation (CH-DILI), which sometimes advances rapidly to liver cirrhosis (LC-DILI) within 0.5-1 year with deteriorative clinical prognosis. Therefore, it is important to find a non-invasive diagnosis for early detection of liver cirrhosis. In this study, the metabolomic profiles revealed significant differences in the metabolites from the plasma of LC-DILI versus CH-DILI. We found 35 differential metabolites through principal component analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA). Through pathway enrichment analysis, some up-regulated metabolic pathways reflected impaired liver functions such as bile acid, lipid synthesis and decomposition during cirrhosis. Five biomarkers were found to exhibit effective diagnosis value (AUC > 0.6), including phosphatidylcholine, lysoPC (18:1 (9Z)), creatine, taurochenodeoxycholic acid and taurocholic acid. Furthermore, we found that the relative content ratio between phosphatidylcholine and lysoPC (18:1 (9Z)) had a better distinguishing ability (AUC = 0.867). The relative content ratio also had the feature to reduce systematic errors of sample processing and instrument detection, therefore having a greater value for clinical application.

To investigate the value of diffusion-weighted imaging(DWI)and apparent diffusion coefficient(ADC)in the diagnosis and differential diagnosis of posterior fossa solid hemangioblastoma(PFSH). We retrospectively analyzed the clinical data of 15 PFSH patients and 58 patients with other hypervascular tumors in the posterior fossa(the latter included 23 cases of meningioma,5 cases of medulloblastoma,8 cases of acoustic neuroma,4 cases of hemangiopericytoma,5 cases of lymphoma,9 cases of metastatic tumor,3 cases of astrocytoma,and 1 case of choroid plexus papilloma)confirmed by operation and pathology.All patients underwent axial DWI scans,and the mean ADC value of solid part of the tumors and the adjacent normal cerebellar white matter were measured,and then the normalized ADC was calculated.In addition, test was used to compare the differences in mean ADC and normalized ADC between these two groups,and receiver operating characteristic(ROC)curve was applied to analyze the diagnostic performance of normalized ADC. Of all the 15 PFSH patients,DWI appeared hypointense in 12 patients and isointense in 3 patients;the signals on ADC maps were isointense or hyperintense;the mean ADC value of PFSHs was(1.881±0.445)×10 mm /s and the normalized ADC was 2.70±0.62.In contrast,in 58 patients with other tumors in the posterior fossa,DWI appeared hyperintense in 51 cases,isointense in 3 cases,and hypointense in 4 cases;the mean ADC value was(0.771±0.202)×10 mm /s,and the normalized ADC was 1.17±0.33.Thus,the ADC value and normalized ADC value were significantly higher in PFSH than in other tumors in the posterior fossa(=9.419,<0.001;=9.184,<0.001).The cut-off value of the normalized ADC for the diagnosis of solid hemangioblastoma was 1.89,with the sensitivity and specificity being 100%and 96.6%respectively,and the area under the ROC curve was 0.989. ADC and normalized ADC are valuable in the differential diagnosis of PFSH from other tumors with abundant blood supply.
