Objective To explore the effect of psychological intervention on the rehabilitation of depressive patients.Methods 183 depressive patients were randomly divided into study group (n=93) and control group (n=90). The study group was given systemic psychological intervention additional to routine medicine for 12 weeks and the control group was given only medication. The efficacy was measured by Brief Psychiatric Rating Scale (BPRS), Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS).Results There is no significant difference in SDS, SAS and BPRS ratings between two groups before the intervention (P>0.05). The scores of anxiety-depression, lacking-activity, thinking-disturbance, SAS and SDS were significantly lower in the study group than in the control group 12 weeks after the intervention(P<0.05). Conclusion Psychological intervention can positively improve the rehabilitation of depressive patients.

Hypoxia is the combined result of tumor over-growth and vascular structural abnormalities.Hypoxia is related to tumor invasiveness,radioresistance,and chemoresistance.18F-fluoromisoni-dzole (18F-FMISO) can selectively bind to hypoxic tissues of malignant tumors,and is thus useful for imaging of tumor hypoxia in cancer diagnosis and treatment.This review summarizes the state-of-art research of 18F-FMISO in comparison with other hypoxic agents when applied to animals and clinical studies.

Objective Chronic heart failure ( CHF) is a disease with high morbidity, and mortality.The study was designed to explore the prognostic value of rest gated SPECT myocardial perfusion ( GSMPI) in patients with chronic heart failure. Methods This study was a prospective study, in which 142 CHF patients was included from January 1, 2011 to December 31, 2012.All patients underwent GSMPI, further, summed rest score ( SRS) , left ventricular ejection fraction ( LVEF) , end-diastolic volume ( EDV) , end-systolic volume ( ESV) and phase standard deviation ( PSD) were recorded.All the patients were followed up.Primary endpoint was the major adverse cardiac events ( MACE) .Additionally, we analyzed the independent predictive factor of MACE occurrence by using the Cox proportional hazard model. Results during the follow-up, MACE occurred in 65 cases.The median time to MACE occur-rence was 28(5-48) months.The 3-year MACE free survival rate was 64.3%.Multivariate Cox proportional hazards regression analysis showed that cardiac function grade[HR(95%CI):1.761(1.087~4.824), P=0.005], NT-proBNP[HR(95%CI):1.153(1.125~5.997), P =0.009], LVEF[HR(95%CI): 1.945(1.138 ~
6.131), P=0.019], SRS[HR(95%CI):1.517(1.108~4.278), P=0.027] and PSD[HR(95%CI):1.442(1.156~5.339), P=0.032] were all independent predictors of MACE. Conclusion GSMPI may be a prognostic factor for the patients with chronic heart failure.

Objective To evaluate the efficacy of moxifloxacin-based triple therapy combined with rebamipide for Helicobacter pylori (Hp) eradication in type 2 diabetic patients.Methods Two-hundred age and sex matched type 2 diabetic patients with Hp infection and accompanied by gastrointestinal symptoms were assigned into rebamipide group (n =100) and placebo group (n =100).Both groups received moxifloxacin-based triple therapy for 10 d to eradicate Hp.Rebamipide was administrated in rebamipide group and placebo was administrated in placebo group for 30 d.All patients proceeded 14C-urea breath test (14C-UBT) hefore and 7-8 weeks after eradication therapy.The blood sugar indices,gastrointestinal symptom scores and Hp eradication rates were measured and compared.Those who had gained successful Hp eradication in both groups proceeded 14 C-UBT again 12 months after eradication therapy,and the re-infection rates of both groups were compared.Results There were no significant differences in the average fasting glucose,postprandial glucose and HbAlc levels between the rebamipide group and the placebo group before and after therapy (P ＞ 0.05),the gastrointestinal symptoms of the rebamipide group were improved more markedly than those of the placebo group after therapy (Rome Ⅲ Criteria,2.1 ± 0.9 vs.4.4 ± 0.7,P ＜ 0.01).The Hp eradication rate with both intention-to-treat (ITT) and per protocol (PP) analysis of the rebamipide group were higher than that of the placebo group [86.0％ (86/100) vs.73.0％ (73/100),P ＜ 0.05 and 92.5％ (86/93) vs.76.8％ (73/95),P ＜ 0.01].The re-infection rates with both ITT and PP analysis of those who had successful eradication in rebamipide group were lower than that in placebo group [19.8％ (17/86) vs.35.6％ (26/73),P＜0.05and20.5％ (17/83) vs.36.6％ (26/71),P＜0.05].Conclusions Moxifloxacin-based triple therapy combined with rebamipide has a more beneficial effect on Hp related symptoms,a higher Hp eradication rate and a lower Hp re-infection rate for type 2 diabetic patients.

Objective To evaluate the value of 18F-FDG and 18F-FLT PET/CT for the detection of primary and regional lymph node metastasis of gastric cancer.Methods Thirty-seven patients with gastric cancer underwent preoperative 18F-FLT and 18F-FDG PET/CT within one week from March 2011 to April 2013.Postoperative histopathology confirmation was obtained in all patients.The PET/CT images were assessed visually and semi-quantitatively.Two-sample t and x2 tests were analyzed using SPSS 13.0.Results For the detection of primary gastric cancer,the sensitivities of 18 F-FLT and 18 F-FDG PET were 89.2％ (33/ 37) vs 91.9％(34/37),respectively (x2=0.158,P＞0.05).The 18F-FLT SUVmax of 16/37 cases with diffuse-type gastric cancer was significantly higher than that of 21/37 cases with intestinal-type gastric cancer (6.89±1.38 vs 3.79±2.45,t=4.533,P＜0.05) ; while 18F-FDG SUVmaxwas not significantly different between the two subgroups (7.13± 1.97 vs 6.36±2.32,t =1.066,P＞0.05).For the detection of regional lymph node metastasis,the sensitivity,specificity and accuracy of 18F-FLT and 18F-FDG were 64.8％(35/54) vs 88.9％(48/54),97.6％(246/252) vs 82.9％(209/252),91.8％(281/306) vs 84.0％(257/306),respectively (x2 =8.796,30.948,8.854,all P＜0.05).The overall sensitivity,specificity and accuracy by both tracers were 92.6％(50/54),98.8％(249/252) and 97.7％(299/306).Conclusions 18F-FLT might be a better or complementary tracer to 18F-FDG for the detection of diffuse-type gastric cancer.Compared with 18FFDG PET/CT,18F-FLT PET/CT may be less sensitive but more specific and accurate for the detection of regional lymph node metastasis.The overall diagnostic accuracy can be improved by using both tracers.

Objective To evaluate the remission situation of early re-induction with priming low dose regimen containing G-CSF in treating acute myeloid leukemia (AML).Methods Ninety-seven AML patients in our hospital from March 2015 to January 2017 were retrospectively analyzed.All cases adopted the standard DA regimen for conducting the induction chemotherapy,among them,38 cases had significant residual disease on 14 d of induction chemotherapy,21 cases adopted the low dose priming regimen for conducting the early re-induction chemotherapy,17 cases adopted the tandard DA gregimen for conducting the re-induction chemotherapy.The complete remission(CR) rate and and adverse reactions were compared between two groups.Results The total CR rate in all 97 cases was 60.8％;among 38 cases needing re-induction chemotherapy,the CR rate in the priming regimen re-induction group was 76.2 ％,which was significantly higher than 41.2 ％ in the DA regimen re-induction group,the difference was statistically significant (P=0.028);the occurrence rates of side effects such as infection and cytopenia during re-induction chemotherapy process had no difference between two groups(P＞0.05).Conclusion For AML patients with obvious residual disease on 14 d of induction chemotherapy,adopting low dose priming regimen in re-duction chemotherapy has higher CR,which is superior to the standard DA regimen.

Osteoarthritis (OA) is a common degenerative disease. Its most significant pathological change is destruction of articular cartilage and the main clinical symptoms are pain and dysfunction of joints. Recent studies have shown that the expression of non-coding RNA (ncRNA) in chondrocytes can abnormally up-regulate or down-regulate and alter the activities of chondrocytes like their proliferation, migration and apoptosis, thus leading to the occurrence and development of osteoarthritis. Exosomes are extracellular vesicles with a diameter of 40-100 nm, which are secreted in intercellular fluid, act as medium of intercellular communication. They protect ncRNA, protein, lipid and other bioactive materials from enzymatic degradation by encapsulating them and transferring to sibling chondrocytes, due to their good tissue permeability. They can also improve communication between cells and regulate the activities of chondrocytes. Thus, exosomes behave like gene carriers. The ncRNA carried by exosomes can supplement or adsorb the abnormal ncRNA in chondrocytes, so as to regulate the activity of chondrocytes, and is therefore considered as a possible candidate with capabilities to repair cartilages. In this study we reviewed existing literatures related to the roles and effects of exosome miRNA, lncRNA and circRNA on osteoarthritis. We also reviewed the pathogenesis of exosome ncRNA in osteoarthritis.

BACKGROUND: Recombinant human bone morphogenetic protein-2 (rhBMP-2) has been widely used on clinic; however, there are still few reports addressing rhBMP-2-induced osteogenesis in intervertebral disc.OBJECTIVE: To verify the effect of rhBMP-2 to induce interbody fusion in rabbits.DESIGN, TIME AND SETTING: Randomized controlled animal study and multi-level evaluation, which was performed in Affiliated Hospital of Medical College of Qingdao University from February to July 2007.MATERIALS: 24 adult New-Zealand rabbits weighing 3.5-4.5 kg were used to expose L4-5 and L5-6 intervertebral disc; rhBMP-2 (1 mg/ampoule, purity≥95%) was provided by Beijing Bailingke Biological Products Co., Ltd.METHODS: 24 rabbits were randomly divided into experimental group and control group with 12 rabbits for each. In the experimental group, saline (20 μL, containing 200 μg rhBMP-2) was injected into nucleus pulposus of L4-5 intervertebral disc; equivalent saline was inserted into nucleus pulposus of L5-6 intervertebral disc as controls. Rabbits in the control group were injected with saline (20 μL) into nucleus pulposus of L4-5 intervertebral disc.MAIN OUTCOME MEASURES: Morphological changes of injected segments were observed by hand-feeling check together with histological and imaging tests at 10, 30, 60, and 90 days postoperatively.RESULTS: 24 rabbits were included in the final analysis. ①In the experimental group, the motion range of L4-5 segment was not limited at 10 days postoperatively, and lightly limited at 30 days, but severely limited at 60 days postoperatively; L4-5 segment was fixed tightly at 90 days postoperatively. Moreover, motion range of L5-6,segment and articular motion range in the control group were not changed remarkably. ② L4-5 interbedy space was narrowed at 10 days or even disappeared at 90 days postoperatively, and then osteogenesis fusion was formed. Transmittance of intervertebral space in the L5-6 segment and in the control group was not changed obviously. ③ Nucleus pulposus was gradually shrunk at 10 days postoperatively; partial cartilage endplate transformed into mature woven bone, and collagen fiber structure of annulus fibrosus gradually disappeared at 90 days postoperatively. A lot of mesenchymal cells were aggregated surrounding annulus fibrosus at 10 and 30 days postoperatively. Moreover, mature woven bone was formed in annulus fibrosus near to cartilage endplate at 90 days postoperatively. However, histological and morphological changes were not found in the control group at those four time points.CONCLUSION: rhBMP-2 can induce intervertebral disc osteogenesis so as to achieve interbody fusion.

Objective To explore the prognostic value of pretreatment 18F-fluorodeoxyglucose (FDG) PET/CT in pediatric neuroblastoma (NB).Methods Twenty-seven NB patients (18 males,9 females;average age (4.6±2.4) years) confirmed by pathology from June 2012 to November 2015 were retrospectively included.All patients had detailed clinical and follow up data.They underwent 18F-FDG PET/CT scan before any treatment,and the largest diameter of primary tumors,maximum standardized uptake value (SUVmax) of primary tumor (Tmax),SUVmax of liver (Lmax),Tmax/Lmax ratio,clinical staging,serum ferritin,serum lactate dehydrogenase (LDH) and serum neuron-specific enolase (NSE) were recorded as prognostic factors.Patients were followed up after treatment for 3-32 months (median:24 months).KaplanMeier survival analysis was used to analyze the influence of Tmax and Tmax/Lmax ratio on 2-year progression free survival (PFS).Cox regression analysis was used to comprehensive analyze the influence of various factors on PFS.Results Of the 27 patients,12(44.4％) experienced disease progression during the follow-up period.Univariate analysis showed that N-myc gene amplification,serum LDH,serum NSE,serum ferritin,the largest diameter of primary tumors,Tmax and Tmax/Lmax ratio were significant prognostic factors for 2-year PFS.The multivariate analysis showed that only the Tmax and Tmax/Lmax,ratio were independent prognostic factors for 2-year PFS.Conclusion 18F-FDG PET/CT can provide effective information on the prognostic information for pediatric NB patients.
