Objective: To evaluate the relationship between the levels of serum uric acid (SUA) and prevalence of coronary artery disease (CAD) by Meta analysis. Methods: We searched the databases of Pub Med, Elsevier and Web of Science for internationally published cohort study for the relationship between SUA levels and CAD prevalence and conducted a general analysisby using Stata software. Results: A total of 11 cohort study including 463,918 subjects were enrolled in this study. For both male and female genders, increase SUA level was the risk factor for CAD occurrence (RR=1.11, 95% CI 1.00-1.24) and (RR=1.24, 95% CI 1.15-1.34). Dose-response Meta-analysis indicated that by 1 mg/dl SUA elevation, the risk of CAD occurrence would increase 4.8% in male and 12.4% in female, the risk in female gender was higher than male. Conclusion: SUA level has been closely related to CAD prevalence.

Objective To study the changes of life span and pathology in superoxide dismutase 1 (SOD1)-G93A mice after intracardiac transplantation of human mesenchymal stem cells (hMSCs).Methods hMSCs were isolated from bone marrow cells obtained from healthy donors and cultured.The purity and morphology were assessed by flow cytometry (FCM).hMSCs (3×10~6) resuspended in 0.2 ml DMEM was injected into the heart of 8 week-old SOD1-G93A mice.In non-transplantion control SOD1-G93A mice, only DMEM was injected.The mice were evaluated for signs of motor deficit with 4-point scoring system previously described by Weydt et al.The age of onset and life span in mice were assessed.The pathological change including number of motor neurons was investigated by Nissl staining.Immunofluorescence staining with specific human nuclear antibody was used to confirm the transplant of hMSCs in mice.Results The onset symptoms in untreated SOD1-G93A mice appeared at (156.56±3.60) days of age and the average life span was (188.32±3.51) days.hMSCs transplantation delayed the onset of ALS type symptoms about 16 days (x~2=10.888, P=0.001) and prolonged the life span about 14 days compared to the untreated SOD1-G93A littermates((202.19±4.09) days vs (188.32±3.51) days, x~2=3.917, P=0.04).The loss of motor neurons in untreated mice was earlier and more severe than in hMSCs transplanted mice.At 20 weeks, the number of motor neurons in transplanted mice was significantly higher than those in untreated mice.Human specific nuclear antigen in brain and spinal cord was detected in transplanted SOD1-G93A mice.Conclusion hMSCs can be implanted for a long-term into central nervous system by intracardiac transplantation and the transplantation can prolong life span, and delay the onset of the disease and motor neuron loss in SOD1-G93A mice.

AIM:To study intravenous transplantation of human mesenchymal stem cells (hMSCs) on the life span and pathological change of SOD1-G93A amyotrophic lateral sclerosis (ALS) mice. METHODS:hMSCs were cultured and expanded from heparinized bone marrow cells from healthy donors and the purity and features were identified with FCM. hMSCs (3×10~6) resuspended in 0.3 mL DMEM or 0.3 mL DMEM only were injected into the tail vein of genotyped SOD1-G93A ALS mice. The mice were evaluated for signs of motor deficit with 4-point scoring system according to Weydt and the onset and life span were assessed. The pathological change was observed with Nissl staining and number of motor neuron was counted. RESULTS:The onset symptoms in untreated SOD1-G93A ALS mice appeared at (156.6±3.6) d of age and the average life span was (188.3±3.5) d. hMSCs transplantation delayed the onset of ALS type symptoms about 14 d and prolonged the life span about 18 d compared to the untreated SOD1-G93A littermates. The loss of motor neurons in untreated mice was much faster and severer than that in hMSCs transplanted mice. At 16 th week and 20 th week,motor neurons of untreated mice were significantly fewer than those of transplanted mice. β-globin gene in brain was detected in transplanted ALS mice. CONCLUSION:hMSCs migrate to central nervous system after intravenous transplantation,prolong the life span and delay the onset and motor neuron loss in SOD1-G93A ALS mice.

AIM: To discuss the essence of Yufeng Capsule(Radix Astragali, Radix et Rhizoma Salviae Miltiorrhizae, Rhizoma Gastrodiae, etc.) on promoting blood circulation and removing blood stasis and its mechanism. METHODS: The parametes of observation included hemorrhedogy、thrombosis、 the function of platelet and content of blood plasma TXB_2 and 6-keto-PGF_ 1? about male old rat model as the blood stasis model. RESULTS: Yufeng Capsule can restrain platelet aggregation obviously(P

Objective:To validate the clinical value of CT-guided curve-needle percutaneous ethanol injection (CNPEI) for celiac plexus block analgesia. Methods: Thirty-two patients with end-stage cancer, including 13 complicated with extensive retroperitoneal lymph node enlargement and fusion, were enrolled in this study. All patients complained of refractory upper abdominal pain and had received narcotic analgesics and radiotherapy, but the analgesic effect was not good. CT-guided CNPEI was therefore prescribed. Results: The effective rates of CT-guided CNPEI were 100%, 100%, 96.9%, 90.6%, 87.5%, and 84.4% immediately,and at 2 weeks, 4 weeks, 8 weeks, 12 weeks, and 16 weeks after treatment, respectively. All enlarged lymph nodes had obvious necrosis and became shrunk. Conclusion: Combined application of bilateral anterior and posterior diaphragmatic crura block and trans-lymph node block can produce good analgesic effects, and curve-needle puncture make the above technique simpler.

Objective:To validate the therapeutic value of CT-guided percutaneous ethanol injection (PEI) in the treatment of metastatic adrenal tumors. Methods: Thirty-one foci (diameter ranging from 1.5 cm to 7.2 cm) in 25 patients with metastatic adrenal tumors were treated with CT-guided PEI for more than twice. Plain and enhanced CT scans were performed 1-2 months after PEI to observe the size and necrosis of the tumors. Results: Post-PEI enhanced CT scan showed that 18 of the 20 foci with diameters less than 3 cm completely necrotized; 11 foci with diameters between 3 cm and 7.2 cm necrotized partially, and 2 foci completely necrotized after another 2-3 courses of PEI treatment. Conclusion: CT-guided PEI is a simple and minimally invasive means for treatment of metastatic adrenal tumors, and the therapeutic effect is satisfactory.

Objective To establish the benign prostatic hyperplasia evaluation index system for nursing quality. Methods Indicators framework for perioperative nursing quality evaluation index system was built up by the theoretical research, clinical research, expert meetings approach firstly, then the Delphi method was used to screen and verify the indicators. Results Two rounds of consultation questionnaires were collected with rate of 86.0%, 95.3% respectively, the first round of consultation had the retention of 13 indicators, removed 4 indicators of those. After the second round, the average score of important target was no less than 8.0, and more than half of indicators had a full mark, coefficient of variation targets no higher than 0.20 were up to 100%. Coefficient of concordance of two rounds were 0.241 and 0.433 respectively. ConclusionsAfter two rounds of consultation, there were 13 quality indicators left and experts had well authoritativeness and representative.

OBJECTIVETo study the clinical effects of Fuzheng Huayu Gantang comprehensive therapeutic program (FHGP) on post-hepatitis B liver cirrhosis associated with glyco-metabolic abnormality (LCGA).

METHODSThe patients with LCGA enrolled in the randomized controlled clinical trial were assigned to 2 groups, the treated group (68 cases) and the control group (74 cases), they were treated respectively by FHGP and conventional TCM and Western medicine therapeutic program for 3 months. Indexes including fasting plasma glucose (FPG), 2 h postprandial plasma glucose (2 h PG), fasting insulin (FINS) were detected, homeostasis model assessment insulin resistance (HOMA-IR) was calculated, and the score of syndrome was recorded before and after treatment. Then the effects on syndrome and glyco-metabolic abnormality were evaluated through statistical analysis.

RESULTSLevel of 2 h PG after treatment was lowered in both groups (P < 0.01), but significant difference was found in the pre-treatment to post-treatment decrement of FPG and HOMA-IR between the two groups (P < 0.05). The syndrome improving rate and the total effective rate on glyco-metabolic abnormality in the treated group were significantly better than those in the control group respectively (85.3% vs 64.9% , P < 0.01; 80.9% vs 62.2%, P < 0.05).

CONCLUSIONFHGP has the capability to improve the syndrome and glyco-metabolic abnormality of patients with LCGA.
