Objective To summarize the experience in treating coronary artery fistula (CAF) by using Guglielmi detachable coils. Methods During the period from July 2009 to November 2014 at the Affiliated Changhai Hospital of Second Military Medical University, interventional treatment of CAF by using Guglielmi detachable coils was performed in 40 patients. The clinical data were retrospectively analyzed. The feasibility, safety and effectiveness of this technique were evaluated. Results Successful transcatheter closure of CAF with Guglielmi detachable coils was achieved in all 40 patients; the average Guglielmi detachable coils used in each patient was(2.33±1.38) coils. No procedure-related complications occurred. Intra-operative angiography showed that residual shunt completely disappeared in 12 patients (30%) and blood flow was significantly decreased in 28 patients (70%). All the patients were followed up for 1-65 months, neither complications such as recurrent bleeding and ischemia nor stenosis and occlusion of related arteries, or fistula cavity rupture occurred. Conclusion The use of Guglielmi detachable coil in interventional treatment of CAF is safe and effective, although its long-term effect needs to be further verified.

Objective To investigate the role of chemokine CXC-ligand 16 (CXCL16) in renal ischemia-reperfusion (I/R) injury in the mice.Methods Twelve healthy male C57BL/6 mice and 12 CXCL16-knockout (CXCL16-KO) mice,aged 8-10 weeks,weighing 20-30 g,were studied.The 12 C57BL/6 mice were randomly divided into 2 groups (n=6 each) using a random number table:C57BL/6 sham operation group (group C-S) and C57BL/6 I/R group (group C-I/R).The 12 CXCL16-KO mice were randomly divided into 2 groups (n=6 each) using a random number table:CXCL16-KO sham operation group (group KO-S) and CXCL16-KO I/R group (group KO-I/R).The right kidney was removed,and the left kidney was exposed,and the renal artery was then clamped for 45 min with atraumatic microclips followed by 24 h reperfusion to establish the model of renal I/R in anesthetized mice.Venous blood samples were taken at 24 h of reperfusion for determination of the serum blood urea nitrogen (BUN) and creatinine (Cr) concentrations.The renal specimens were obtained at 24 h of reperfusion for microscopic examination of the pathological changes,and the damage to the renal tubules was scored.The number of myeloperoxidase (MPO) positive cells (MPO+ cells),F4/80+ cells and CD3+ cells in renal tissues was counted by immunohistochemistry.The expression of tumor necrosis factor-alpha (TNF-α),interleukin-1beta (IL-1β),IL-6,and macrophage inflammatory protein-2 (MIP-2) mRNA in renal tissues was determined by real-time reverse transcriptase polymerase chain reaction.Results Compared with group C-S,the serum BUN and Cr concentrations,renal tubular damage score,and the number of MPO+,F4/80+,and CD3+ cells were significantly increased,and the expression of TNF-α,IL-1β,IL-6 and MIP-2 mRNA was significantly up-regulated in group C-I/R (P＜0.05).Compared with group KO-S,the serum BUN and Cr concentrations,renal tubular damage score,and the number of MPO+,F4/80+,and CD3+ cells were significantly increased,and the expression of TNF-α,IL-1β,IL-6 and MIP-2 mRNA was significantly up-regulated in group KO-I/R (P＜0.05).Compared with group C-I/R,the serum BUN and Cr concentrations,renal tubular damage score,and the number of MPO+,F4/80+,and CD3+ cells were significantly decreased,and the expression of TNF-c,IL-1β,IL-6 and MIP-2 mRNA was significantly down-regulated in group KO-I/R (P＜0.05).Conclusion CXCL16 is involved in the pathophysiological process of renal I/R injury in the mice.

ObjectiveTo evaluate the clinical outcome of new proximal femoral nail antirotation (PFNA) in treatment of subtrochanteric fractures. MethodsThere were 31 patients with traumatic subtrochanteric fractures intramedullarily fixed with PFNA. The patients included 14 males and 17 fe-males at a mean age of 54.6 years (range 34-90 years). According to Seinsheimer classification of sub-trochanteric fractures, 14 patients were with type Ⅱ fractures (including four patients with type ⅡA,seven with type ⅡB and three with type ⅡC), 12 with type Ⅲ fractures (including eight with type ⅢA and four with type ⅢB), two with type Ⅳ fractures and three with type Ⅴ fractures. Close reduction was performed under traction and C-arm fluoroscopy in 26 patients and open reduction through a mini-incision before inserting the nail in five patients due to difficult close reduction. ResultsThe operation lasted for a mean time of 72.5 minutes (range 45-120 minutes), with mean blood loss of 127.5 ml (range 100-350 ml). Of all, 27 patients (87.1%, 27/31) were followed up for a mean duration of 14.3 months (range 8-24 months), which showed fracture union in all patients, with a mean union period of 17.4 weeks (range 10-21 weeks). According to Harris Hip Rate Scale, the results were. excellent in 21 pa-tients, good in two and fair in four, with excellence rate of 85.2% (23/27). ConclusionsPFNA is an effective device for treatment of subtrochanteric fracture, with a high union rate and a low complication rate, for it has advantages of easy use and minor trauma, low bleeding and stable fixation in operation.

Objective:To determine the effect of hypoxic stress on glioma cell XBP1 expression, the relationship between XBP1 expres-sion and sugar metabolism, the influence of XBP1 repression on the survival rate of glioma cells under normoxia and hypoxia, and the influence of XBP1 on glioma cell glycolysis. Methods:We tested XBP1 activation in human glioma cell lines cultured under normoxia and hypoxia. XBP1 expression was repressed with siRNA technology. Cells were treated with oxidative phosphorylation inhibitor. We then detected the variation in cell apoptosis, sugar metabolism mode, and cell apoptosis and glycolysis products under normoxia and hypoxia. Results:XBP1 activation increased under hypoxia. Silencing XBP1 expression reduced glioma cell survival level, ATP and lactic acid production, and glucose consumption under hypoxia. After inhibiting cell oxidative phosphorylation, XBP1 repression significantly reduced the survival level of glioma cells. Conclusion:Hypoxia can activate XBP1 in glioma cells. Under hypoxia, XBP1 silencing de-presses cell activity and glycolysis. Glycolysis of glioma cells under hypoxia depends on XBP1 activation.

Objective To investigate the related risk factors of contrast-induced acute kidney injury (CI-AKI)after cerebrovascular intervention. Methods The clinical data of 5423 patients performed cerebrovascular angiography and intervention at the Departments of Neurology and Neurosurgery,Guangdong People′s Hospital from January 2005 to December 2013 were analyzed retrospectively. The patients who underwent cerebrovascular angiography and intervention were evaluated and screened. A clinical history database was established. All the selected patients used iodixanol,an isotonic contrast agent. The occurrence of CI-AKI was used as an endpoint. The patients were divided into either a CI-AKI group or a non CI-AKI group. A multivariate Logistic regression model was used to analyze the risk factors associated with the occurrence of CI-AKI. Results A total of 4164 patients were finally enrolled,including 137 had CI-AKI. The incidence of CI-AKI was 3. 3%. The results of multivariate Logistic regression showed that age >60 years (OR,1. 965,95%CI 1. 244-3. 136),baseline estimated glomerular filtration rate (eGFR)<60mL/(min·1. 73 m2)(OR,4. 163,95%CI 2. 422-5. 873),diabetes (OR,3. 140,95%CI 1. 983-3. 902),and anemia (OR,1. 524,95%CI 1. 226 -3. 253)were the influencing factors for occurring CI-AKI after cerebrovascular angiography and intervention. Conclusion Chronic kidney disease (eGFR<60 mL/[min·1. 73 m2 ]),diabetes,anemia,and old age (age >60 years)are the independent risk factors for occurring CI-AKI after cerebrovascular angiography and intervention.

Objective:To detect the factors related to hemocytopenia and interstitial lung disease (ILD) secondary to primary Sj?gren's syndrome (pSS) in in-patients.Methods:Clinical characteristics of patients with pSS hospitalized in China-Japan Friendship Hospital from March 2014 to October 2020 were retrospectively analyzed. Patients were divided into different groups according to hemocytopenia and ILD. Chi-square test and Mann-Whitney U test were used to compare data in subgroups, and logistic regression were used to detect factors related to hemocytopenia and ILD secondary to pSS. Results:Five hundred and seventy-one inpatients with pSS were included in this study and the female: male ratio was 8∶1. Two hundred and seventy five of included patients had hemocytopenia (48.2%) and 180 patients had ILD (31.5%). Compared with patients without hemocytopenia, patients with hemocytopenia had higher ratio in low C3 [ OR=2.326, 95% CI(1.483, 3.650), P<0.01] and elevation of erythrocyte sedimentation rate (ESR) [ OR=1.912, 95% CI(1.233, 2.964), PP<0.01) . Compared with patients without ILD, patients with ILD showed higher ratio in male[ OR=2.509, 95% CI(1.269, 4.959), P<0.01) and fatigue [ OR=5.190, 95% CI(5.190, 13.931), P<0.01) , lower positive rate of anti-SSA antibody [ OR=0.392, 95% CI(0.230, 0.668), P<0.01) and anti-CENPB [ OR=0.337, 95% CI(0.145, 0.782), P<0.01] antibodies, and lower ratio in low C3[ OR=0.332, 95% CI(0.189, 0.582), P<0.01]. Conclusion:Low C3 and high ESR may be risk factors for developing hemocytopenia in patients with pSS. Men with pSS may be susceptible to ILD, while pSS patients with ILD may have lower ratio in positive anti-SSA antibody, positive anti-CENPB antibody and low C3. All of these findings are yet to be validated by future prospective cohort studies.

We have investigated the effects of repairing knee osteochondral defects in rabbit by using porous polyamide 66/nano-Hydroxyapatite (PA66/n-HA) combination bone marrow mesenchymal stem cells (MSCs). Eighteen 6-month-old New Zealand rabbits were used to produce the models of 4 mm x 4 mm osteochondral defect in the middle trochlea groove of femur. These models were randomly divided into 3 groups: PA66/n-HA + MSCs Group (Group A), PA66/n-HA group (Group B) and Operation control-group (Group C) in which operation for osteochondral defects was performed but neither material nor cells were implanted. The materials in Group A were seeded with MSCs (5 x 10(5)) in vitro before being implanted in to defects. The materials in groups A and B were 0.5 - 0.8 mm lower than normal cartilage. The animals were killed 1 and 4 months after operation. We assessed the effects by means of macroscopic observation, HE staining, toluidine blue staining, immunohistochemistry assay for type I and type II collagen. Group A displayed a little effect at the 1 month, but at the 4th month, Group A showed better results,compared to Groups B and C. At this time point, the repair tissue of Group A was regular; it presented more metachromatic substance visualized by toluidine blue staining, and it expressed type II collagen(+ +) and type I collagen(+). These results demonstrate that the repair tissue in Group A is nearly hyaline cartilage. So we presume that porous PA66/n-HA provides biomechanical support, and at the same time, MSCs enhance the repair effects.

Histone deacetylase 8(HDAC8)is a zinc-dependent class I histone deacetylase, closely related to human pathophysiology. HDAC8 involves in various critical signaling networks and is implicated as a therapeutic target in various diseases, including cancer, X-linked intellectual disability and parasitic infections. More and more selective HDAC8 inhibitors have been developed based on deepening study of its well-characterized crystal structure. They are mainly divided into several categories such as phenyl hydroxamic acids, indoles, ortho-aryl-N-hydroxycinnamides, azetidinones etc. . Current challenges remain in the development of potent selective inhibitors that would specifically target HDAC8 with fewer adverse effects compared with pan-HDAC inhibitors. Herein, we reviewed the progress in the study of structure and functions of HDAC8 as well as the development of selective HDAC8 inhibitors.

BACKGROUND: Minimally invasive and rapid recovery are trends in surgical treatment of lung cancer, and Da Vinci Surgical Robotic System plays an important role in them. This study was planned to explore the effect of chest wall external nursing interventions on reducing postoperative thoracic drainage and promoting rapid recovery of patients. METHODS: The patients who underwent robotic radical lung cancer resection in our hospital from November 2017 to April 2018were randomly divided into two groups. The control group received robotic radical lung cancer resection with abdominal bands wrapped around the chest. The experimental group underwent Da Vinci robotic radical lung cancer surgery and assisted chest wall external nursing interventions after surgery. RESULTS: The total and average daily drainage of the experimental group were less than those of the control group. Both the extubation time and the hospitalization time were shorter than those of the control group, but there was no significant difference. The pain score in the second days after operation of the experimental group was slightly higher than that of the control group, with no significant statistical difference. For patients whose chest wall thickness is less than 4 cm, mirabilite external application can significantly reduce the average daily and total drainage volume, but there is no significant difference in extubation time and hospitalization time. CONCLUSIONS Chest wall external nursing interventions are beneficial to the recovery of patients undergoing Vinci robotic lung cancer surgery. Especially for patients with thinner chest wall. It can reduce postoperative drainage, shorten tube retention time and accelerate discharge. Further improvement is expected to achieve better clinical results.
