Objective To investigate the relationship between serum phospholipid polyunsaturated fatty acids (PUFA) and interleukin-6 (IL-6) in patients with metabolic syndrome.Methods Serum phospholipid PUFA profiles of 61 patients with metabolic syndrome and 55 healthy controls was analyzed with high performance gas chromatography.Enzyme-linked immunosorbent assay was used to measure serum IL-6 levels.Results The IL-6 concentration was significantly higher in the MS group than in the control group [(16.0 ± 4.7) pg/ml vs.(9.2 ± 2.6) pg/ml,P =0.000].The total PUFA percentage was lower in the MS group than in the control group [(47.2±2.4)％ vs.(50.8 ±2.5)％,P=0.001].The serum IL-6 concentration was negatively correlated with n-3 PUFA,n-6 PUFA,and total PUFA (r =-0.51,P ＜0.01;r=-0.27,P＜0.01;r=-0.38,P＜0.01).Conclusions Serum PUFA in patients with metabolic syndrome is lower than in healthy people.Serum IL-6 concentration may be negatively correlated with total PUFA concentration.

Objective To investigate characteristics of free fatty acid (FFA) and high-sensitivity Creactive protein (hs-CRP) in patients with type 2 diabetes mellitus and metabolic syndrome (MS) compared to those with type 2 diabetes mellitus without MS.Methods Totally 120 patients with type 2 diabetes mellitus who received blood glucose control in Shaoxing People's Hospital from January to June 2013 were recruited and divided into MS group (n =56) and non-MS group (n =64).The serum FFA profile of the patients was measured by enzymatic assay, and the serum hs-CRP level measured by particle-enhanced immuno-precipitation assay.Results The level of FFA was higher in the MS group than that in the non-MS group [(0.60 ±0.25) mmoL/L vs.(0.45 ±0.21) mmol/L, P =0.033].The level of hs-CRP was higher in the MS group than that in the non-MS group [5.29 (4.69-5.82) mg/L vs.0.73 (0.42-1.26) mg/L, P =0.000].The level of hs-CRP was higher in the patients with central obesity than that in those without central obesity [4.34 (0.91-5.46) mg/L vs.1.80 (0.82-3.27) mg/L, P=0.014], also higher in hypertensive patients than in non-hypertensive patients [5.21 (3.18-5.96) mg/L vs.2.93 (0.89-4.98) mg/L, P =0.012].Conclusions Serum FFA and hs-CRP concentrations may be significantly higher in type 2 diabetes mellitus patients with MS.The increased levels of FFA and hs-CRP may play an important role in the pathogenesis of type 2 diabetes mellitus and MS.

Objective To investigate the relationship between triglyceride and serum polyunsaturated fatty acid (PUFA) in patients with metabolic syndrome (MS).Methods Totally 74 MS patients (MS group) and 62 healthy subjects (normal control group,NC group) were recruited from June 2011 to June 2012 in Shaoxing People's Hospital.Serum phospholipid fatty acid profiles were analyzed with capillary gas chromatography.Serum lipids were measured by enzymatic assay.Results The triglyceride concentration was significantly higher in MS group than that in NC group [(2.0 ±0.8) mmol/L vs.(1.3 ±0.5) mmol/L,P=0.000].The levels of n-3 PUFA,n-6 PUFA,and PUFA were significantly lower in MS group than those in NC group (9.8％ ±2.2％ vs.11.1％ ±2.4％,P=0.002; 35.4％ ±6.7％ vs.39.5％ ±7.8％,P=0.009; 45.2％ ±8.9％ vs.50.6％ ±10.1％,P =0.000).Triglyceride concentration was inversely correlated with n-3 PUFA and PUFA levels (r =-0.42,P =0.008 ; r =-0.23,P =0.013).Conclusions n-3 PUFA,n-6 PUFA,and PUFA decrease in MS patients.Triglyceride concentration is inversely correlated with PUFA.

Objective:To investigate the image characteristics of woven coronary artery (WCA)on intravascular ultrasound(IVUS) and optical coherence tomography(OCT).Methods:Thirty-seven patients suspected of WCA on coronary angiography were enrolled from Teaching Hospital of Chengdu University of Traditional Chinese Medcine, Zhengzhou Cardiovascular Disease Hospital and Zhongshan Hospital of Fudan University from January 2013 to July 2020. The intraluminal imaging features of WCA were analyzed using IVUS and OCT.Results:Of the 37 patients admitted at the cardiology service, 9 patients had WCA. All the patients underwent coronary angiography, IVUS and OCT, of which 6 lesions were located on the right coronary artery, 2 lesions were located on the left anterior descending artery and 1 patient had WCA on the circumflex artery. The mean length of WCA lesions was 2.2 cm(ranged from 1.2 cm to 4.5 cm). The angiographic appearance of WCA was numerous small tortious channels origined form the main lumen. The channels appeared to be " doughnut" like pattern and they merged to normal artery again after the anomalous segment. Flow limitation was rare unless there was coronary atherosclerosis. OCT and IVUS showed multiple spiral channels in the anomalous segment, which were independent of each other and each channels had a relatively complete three-layers vascular structure.Conclusions:With typical image characteristics, IVUS and OCT are able to screen out WCA and guide the treatment decision making.

Objective To investigate the feasibility and clinical value of medical history and clinical manifestation-based protocol(MHCMP) for the diagnosis of spontaneous coronary artery dissection(SCAD)using intravascular ultrasound (IVUS).Methods Based on the MHCMP designed in our centre,intraoperative sequential analysis was performed in patients with acute coronary syndrom and clinical tip of SCAD,SCAD and its classification were defined according to the result of IVUS.Results Of the 37 patients admitted with ACS at the Cardiology Service,29 patients had SCAD as the cause(78.4 ％).All the patients underwent coronary angiography and IVUS,of which 9 patiens were type I (24.3 ％),15 patients were type Ⅱ (40.5％) and 5 patients were type Ⅲ (13.5％).The left anterior descending artery was the most frequently affected (16 patients),followed by the the right coronary artery (7 patients),while 5 patients had dissection of the circumflex artery and 1 patient had dissection of the left main coronary artery.Type I (evident arterial wall stain):this was the pathognomonic angiographic appearance of SCAD with contrast dye staining of the arterial wall with multiple radiolucent lumens.Type Ⅱ (diffuse stenosis of varying severity):this angiographic appearance was not well appreciated and was often missed or misdiagnosed.SCAD commonly involved the mid to distal segments of coronary arteries,and could be so extensive that it reached the distal tip.There was an appreciable (often subtle) abrupt change in arterial caliber,with demarcation from normal diameter to diffuse narrowing.This diffuse and usually smooth narrowing could vary in severity from inconspicuous mild stenosis to complete occlusion.Type Ⅲ (mimic atherosclerosis):this appearance was the most challenging to differentiate from atherosclerosis and most likely to be misdiagnosed,while IVUS was helpful for the differential diagnosis.Conclusions MHCMP is able to screen out all kinds of SCAD and guide the treatment decisions making.

Apogossypolone (ApoG2), a novel derivative of gossypol, has been shown to be a potent inhibitor of antiapoptotic Bcl-2 family proteins and to have antitumor activity in multiple types of cancer cells. Recent reports suggest that gossypol stimulates the generation of cellular reactive oxygen species (ROS) in leukemia and colorectal carcinoma cells; however, gossypol-mediated cell death in leukemia cells was reported to be ROS-independent. This study was conducted to clarify the effect of ApoG2-induced ROS on mitochondria and cell viability, and to further evaluate its utility as a treatment for nasopharyngeal carcinoma (NPC). We tested the photocytotoxicity of ApoG2 to the poorly differentiated NPC cell line CNE-2 using the ROS-generating TL/10 illumination system. The rapid ApoG2-induced cell death was partially reversed by the antioxidant N-acetyl-L-cysteine (NAC), but the ApoG2-induced reduction of mitochondrial membrane potential (MMP) was not reversed by NAC. In the presence of TL/10 illumination, ApoG2 generated massive amounts of singlet oxygen and was more effective in inhibiting cell growth than in the absence of illumination. We also determined the influence of light on the anti-proliferative activity of ApoG2 using a CNE-2-xenograft mouse model. ApoG2 under TL/10 illumination healed tumor wounds and suppressed tumor growth more effectively than ApoG2 treatment alone. These results indicate that the ApoG2-induced CNE-2 cell death is partly ROS-dependent. ApoG2 may be used with photodynamic therapy (PDT) to treat NPC.

Objective:To investigate the clinical characteristics of infantile neuroblastoma (NB) and the factors that affect prognosis.Methods:We retrospectively analyzed the clinical data collected from 44 cases of NB who received treatment in The Fourth Affiliated Hospital of China Medical University from March 2008 to March 2017 to summarize the clinical characteristics of NB and the factors that affect prognosis.Results:Among the 44 cases, 21 were male and 23 were female, with a median age of 5.5 months (range, 0 days-12 months). Four cases had stage I NB, seven cases stage II NB, five cases stage III NB, 15 cases stage IV NB, and 13 cases stage IVs NB. The tumors were located in the adrenal glands and retroperitoneum ( n = 26, 59.1%), posterior mediastinum ( n = 15, 34.1%), pelvis ( n = 2, 4.5%), and neck ( n = 1, 2.3%). The median follow-up time was 90 months (range, 2-144 months). The 3-year and 5-year overall survival rates were 93.2% and 90.9%, respectively. Among 35 cases who survived more than 5 years, 30 cases survived healthily, 5 cases survived with tumor, and 4 cases died. Bone marrow metastasis, bone metastasis, and the extent of tumor resection greatly affect the prognosis of NB ( χ2 = 6.92, 12.19, 4.70, all P < 0.05). Conclusion:The overall prognosis of NB is good in infants. NB mainly occurs in the abdomen. The survival rate of infants with stage IVs NB is lower than that of infants with stages I, II, and III NB. The prognosis of NB occurring in the abdomen is poorer than that occurring in other regions. Bone marrow metastasis, bone metastasis, and the extent of tumor resection are adverse factors affecting the prognosis.

Objective:To explore the relationship between carotid atherosclerosis (CAS) and bone metabolism marker osteocalcin (OC) in patients with type 2 diabetes (T2DM).Methods:A total of 100 patients with T2DM admitted to Shaoxing People's Hospital (Shaoxing Hospital, Zhejiang University) from January 2018 to August 2018 were selected as study subjects, and the carotid intima-media thickness (IMT) was detected.The patients were divided into CAS group and normal carotid IMT group (NC group), with 50 cases in each group.The levels of OC, fasting plasma glucose(FPG), fasting insulin(FINS), glycosylated hemoglobin(HbA1c), total cholesterol (TC), triglyceride (TG), high density lipoprotein(HDL-C), low density lipoprotein (LDL-C), insulin resistance index (HOMA-IR) were compared between the two groups.Results:The OC level of the CAS group[(11.86±4.46)ng/mL] was significantly lower than that of the NC group[(23.94±4.52)ng/mL] ( t=-9.640, P=0.001). The LDL-C level of the CAS group[(2.89±0.82)mmol/L] was significantly higher than that of the NC group[(2.55±1.16)mmol/L]( t=2.03, P=0.049). Pearson correlation analysis showed that IMT was positively correlated with age, LDL-C, HbA1c ( r=0.285, 0.190, 0.173; P=0.000, 0.020, 0.035), and negatively correlated with OC ( r=-0.603, P=0.000). Conclusion:CAS in patients with T2DM is closely related to OC, and the reduction of OC levels may be a risk factor for CAS in T2DM patients.

Objective:To determine the influences of structural changes after valgus impacted femoral neck fracture on hip range of motion (ROM) so as to provide evidence for clinical judgment of whether reduction is necessary or not in the internal fixation of such fractures.Methods:1. 3D reconstructions of the CT hip scans were performed for the 73 patients who had been treated at Department of Orthopaedic Surgery, Shanghai Sixth People’s Hospital Affiliated to Shanghai Jiao Tong University for valgus impacted femoral neck fractures from January 2019 to April 2019.The femoral neck-shaft angle, anteversion angle, femoral offset, axial alpha angle, lateral center edge angle (LCEA), anterior center edge angle (ACEA) and center displacement were measured and compared between the affected and healthy sides to determine the influences of the fracture on the above indexes. 2. Hip motions (flexion and MIR-90°) were simulated on bilateral sides to determine the influences of structural changes after fracture on hip ROM using stepwise regression and Logistic regression. 3. The distribution of femoral-acetabular contact points on the femoral side was observed in simulation of hip flexion to detect the potential area for femoracetabular impingement (FAI) induced by the fracture displacement.Results:1. The valgus impacted femoral neck fractures had significant influences on femoral neck-shaft angle, anteversion angle, femoral offset and axial alpha angle. Compared with the healthy side, on average, the femoral neck-shaft angle increased by 5.1°, anteversion angle decreased by 6.5°, femoral offset decreased by 8.2 mm and axial alpha angle increased by 9.7° on the affected side, showing significant differences ( P<0.05).The displacements of the femoral head center averaged 9.2 mm. There was no significant difference in LCEA or ACEA between the affected and healthy sides ( P>0.05). 2. Compared with the healthy side, on average, the simulated hip flexion decreased significantly by 27.0° and the hip MIR-90° decreased significantly by 20.3° on the affected side after fracture ( P<0.05). Regression analysis showed that femoral anteversion angle, ACEA and displacement of the femoral head center had a significant influence on hip ROM, especially the anteversion angle. When the anteversion angle decreased by more than 7.1°, the hip flexion would decrease by at least 20%. 3. The points of FAI distributed more widely on the fracture side. Compared with the healthy side, the impact points extended outward and upward in hip flexion and extended inwardly in hip MIR-90° on the affected side. Conclusions:After a valgus impacted femoral neck fracture, if the femoral anteversion angle has been decreased by more than 7.1°, the hip ROM can be greatly influenced and the points of FAI can be distributed more widely. Therefore, reduction should be recommended before internal fixation of the fracture.

Depression is a frequently-seen mental disorder that profoundly affects the survival and quality of life of individuals.Present clinical medicine therapies for depression are not fully efficacious and novel therapeutic agents and targets remain necessary.Bupleuri Radix-Paeoniae Radix(BR-PRA),an essential and crucial compo-nent of traditional antidepressant compound,possesses the beneficial effect of lowering toxicity and amplifying the antidepressant effect when utilized in combination.The underlying mechanisms of these synergistic effects may involve the suppression of inflammation and oxidative stress,the regulation of monoamine neurotransmitters,brain-derived neurotrophic factors,the modulation of the hypothalamus-pituitary-adrenal axis,and the metabolism of various amino acids and energy.This article summarizes the synergistic effects and antidepressant pharmacological effects of BR-PRA herb-pair,thereby providing valuable insights into the potential advantages of this combination and its potential mechanisms of antidepressant action.
