OBJECTIVETo explore the clinical effects of Dynesys system combined with posterior lumbar interbody fusion (PLIF) in treating multiple lumbar degenerative disease.

METHODSThe clinical data of 46 patients with multiple lumbar degenerative diseases treated by Dynesys system combined with PLIF from September 2010 to May 2013 were retrospectively analyzed. There were 17 males and 29 females, aged from 38 to 68 years old with an average of (56.38±11.63) years. Operation section was in L2-L5 of 16 patients (6 with fusion of L4,5 and 10 with fusion of L4,5,L5S1) and in L3-S1 of 30 patients (11 with fusion of L5S1 and 19 with fusion of L4,5,L5S1). Patients were followed up for three times: postoperative 3 months, 1 year and final follow-up. Visual analogue scale (VAS) and Oswestry Disability Index (ODI) were used to assess clinical symptoms preoperatively and postoperatively. All patients underwent flexion/extension radiographs examinations before surgery and at final follow-up. Range of motion (ROM) and disc height index (DHI) were recorded.

RESULTSAll patients were followed up from 16 to 48 months with the mean of (23.23±7.34) months. At third follow-up after operation, ODI and VAS of lumbago and leg pain were significant improved than that of preoperative (P<0.01). DHI of fusion segment was significantly increased than that of preoperative (P<0.05). There was no significant difference in adjacent non-fusion segment between preoperative and postoperative (P>0.05). Postoperative ROM of fusion and non-fusion segments were obviously decreased than that of preoperative. There was no significant difference in ROM of upper adjacent non-fusion segment between 3 months and 1 year after operation (P>0.05), but at final follow-up, the ROM was increased (P<0.05).

CONCLUSIONThe preliminary clinical results of the Dynesys system combined with PLIF in the treatment of multiple lumbar degenerative diseases are satisfactory. It can be determined in fusion or non-fusion according to the individual needs and can reserve the some intervertebral motion, prevent the early degeneration of adjacent segments. However, its long-term clinical efficacy should be verified with long time.

Objective To investigate the relationship between dyslipidemia,obesity,insulin resistance (IR)and various degrees of non.alcoholic fatty liver disease(NAFLD)in patients with type 2 diabetes mellitus (T2DM), and the risk factors of NAFLD.Methods Two hundred and sixty-eight patients were divided into three groups(non-NAFLD group,mild NAFLD group,moderate and severe NAFLD group)by liver ultrasonography.Body height(H),weight(W),waist circumference(WC),hip circumference(H)were measured.The levels of fasting blood glucose (FBG),glycosylated hemoglobin A_1c(GHbA_1C),serum total cholesterol(TC),serunl high density lipoprotein(HDL-C),serum low density lipoprotein(LDL-C),serum triglyceride (TG),alanine aminotransferase (ALT)and fasting serum insulin(FINS)were measured.Body mass index(BMI),the waist to hip ratio(WHR)and insulin resistance index(HOMA-IR)were calculated.Unconditional logistic regression model was used to test for the risk factors of NAFLD.Results BMI、WC、WHR、HNS、HOMA.IR、TC、LDL-C、TG and ALT in NAFLD group were significantly higher than those in non-NAFLD group (P<0.05).The levels of BMI、WC、WHR、HNS、HOMA-IR、 TG and ALT increased significantly in moderate and severe NAFLD group compared with mild NAFLD group(P<0.05).TG、WHR and HOMA.IR were the risk factors of NAFLD(P<0.05,OR=2.394,3.273,5.256).Conclusions NAFLD in patients with T2DM had remarkable dyslipidemia,overweight,central obesity and insulin resistance.TG、WHR and HOMA.IR were risk factors of NAFLD.

[Objective] To investigate the clinical characteristics and risk factors of lower-extremity arterial disease in the patients with newly diagnosed type 2 diabetes mellitus combined with nonalcoholic fatty liver disease (NAFLD). [Methods] One hundred fifty-one patients were investigated respectively. The patients were divided into two groups (NAFLD-Group and non-NAFLD group) by liver ultrasonography and disease history, then their clinical data were collected and compared in order to find the differences of biochemical indicators and the morbidity of lower-extremity arterial disease between two groups. [Results] Ninety-two cases (60.93%) were complicated with NAFLD. NAFLD group had higher levels of fast insulin and C peptide level, postprandial insulin and C peptide level, uric acid, body mass index (BMI), homeostasis model assessment (HOMA-IR) and lower level of high-density lipoprotein cholesterol and insulin sensitive index than those of without NAFLD (P<0.05). One hundred and one cases(66.89%) were complicated with lower-extremity arterial disease. The morbidity of lower-extremity arterial diseases was higher in NAFLD group than that of without NAFLD group (75% vs. 54.24%, P<0.01). [Conclusion] Both lower-extremity arterial disease and NAFLD are common complicated with type 2 diabetes. The morbidity of lower-extremity arterial diseases was higher in NAFLD group than that of without NAFLD group.

Objective To explore the difference of resting-state default-mode network functional connectivity in patients with treatment-resistant depression (TRD) and in healthy subjects. Methods Ten patients with TRD and 12 healthy control subjects underwent 440 s fMRI scans while resting quietly. Functional connectivity analysis was used to isolate the default mode network in each subject. Group maps of the default-mode network were generated and compared between the two groups. A within-group analysis was performed in the depressed group to explore effects of depression refractoriness on network functional connectivity. Results Functional connectivity of both side of middle temporal gyrus, rectal gyrus, precuneus gray matter, left orbital gyrus, right inferior parietal lobule, and post cingulate gyrus in TRD group weakened compared with that of the control subjects. Conclusion There are resting default network connection weakening in multiple brain areas in TRD patients, which may lead to self-control and emotional behavior abnormal in patients.

OBJECTIVETo study the expression level and intracellular localization of APOBEC3G in peripheral blood mononuclear cells (PBMCs) and liver tissues of chronic HBV patients.

METHODSThe expression level and intracellular localization of APOBEC3G in PBMCs and liver tissues were detected using the western blot and confocal laser scanning microscope (CLSM).

RESULTSWestern-blot showed that the expression level of APOBEC3G in PBMCs of healthy controls was very low. The relative expression levels of APOBEC3G in PBMC of patients with chronic hepatitis B, chronic severe hepatitis, liver cirrhosis, or liver cancer were 4.12+/-0.21, 4.07+/-0.28, 4.16+/-0.36 or 4.21+/-0.39 respectively, which were higher than that in the healthy controls. However, there was no significant difference in APOBEC3G expression among different chronic HBV patients (q = 0.931, 0.744, 1.675, 1.675, 2.606 or 0.931, respectively, all P values more than 0.05). In addition, there was no significant difference on APOBEC3G in liver tissues between chronic hepatitis B patients and hepatocellular carcinoma patients (4.40+/-0.34 vs 4.34+/-0.43, q = 0.588, P more than 0.05). CLSM indicated that the localization of APOBEC3G protein was in cytoplasm of PBMCs and hepatocytes.

CONCLUSIONAPOBEC3G is upregulated in the PBMCs of chronic hepatitis B patients.

OBJECTIVESTo evaluate the characteristic morphology of heel spur, and to investigate the relationship of heel spur and plantar heel pain.

METHODSFrom June 2005 to April 2009, 210 cases (254 feet) with heel spur (according to Denis Pain Scale) were divided into cases group 1 (P2, n = 46), 2 (P3, n = 44), 3 (P4, n = 42), 4 (P5, n = 36) and controls group (P1, n = 42). Three-dimensional reconstruction of heel spur was performed in all groups using volume rendering based on multi-slice CT data by Super Image orthopedics edition 1.0. The characteristic morphology of heel spur was observed and the data were measured and analyzed, involving the width of basilar part, the length, the angle between heel spur and planta pedis, and the angle between the longitudinal axis of calcaneus and heel spur.

RESULTSParts of cases groups displayed coarse arcuate edge and undersurface with one or more little heel spurs adhere to heel spur, of which the numbers were greater than controls group, especially in cases group 4. No significant difference of the width of basilar part of heel spur was found among 5 groups (F = 2.32, P > 0.05). However, obvious difference was found in the length, the angle between heel spur and planta pedis, and the angle between the longitudinal axis of calcaneus and heel spur (F = 8.23, 6.82, 5.87, P < 0.05). Compared with the controls group, the angle between heel spur and planta pedis of cases groups had higher degrees, but the difference of the other data presented irregular.

CONCLUSIONSThe characteristic morphology of heel spur varies in patients associated with plantar heel pain. No correlation is found between the severity and the morphological data, including the width of basilar part, the length, the angle between heel spur and planta pedis, and the angle between the longitudinal axis of calcaneus and heel spur.
