The effects of continuous subcutaneous insulin injection (CSII, n=306) and multiple subcutaneous insulin injection (MSII, n=310)on hyperglycemia in patients with diabetes mellitus were compared. The results suggest that the effect of CSII is more prompt and efficient with lower incidence of hypoglycemia as compared with MSII.

ObjectiveTo determine whether antibiotic prophylaxis can reduce the risk of postoperative infective complications in men undergoing transrectal prostatic biopsy (TPB) who had sterile preoperative urine.MethodsMEDLINE, EMBASE, Cochrane Collaboration Reviews, Chinese Medical Current Contents (CMCC), and National Knowledge Infrastructure (CNKI) were searched for rando-mized controlled trials that compared the effect of antibiotic prophylaxis with placebo or active controls for men undergoing TPB with preoperative sterile urine. Two reviewers independently extracted the data of patient characteristics and outcomes based on a prospectively developed protocol.ResultsA total of 12 trials (3 placebo controlled, 3 non-treatment controlled, and 6 activly controlled) involving 1 987 patients, met the inclusion criteria. Prophylactic antibiotic use in patients at low risk undergoing TPB significantly decreased bacteriuria and middle degree fever incidence, but could not decrease the incidence of bacteremia. The relative risk for post-TPB bacteriuria, middle degree fever, and bacteremia were 0.32 (95% CI 0.23 to 0.46), 0.37 (95% CI 0.17 to 0.77), and 0.96 (95% CI 0.61 to 1.50), respectively. Effective antibiotic classes included quinolone, co-quinolone and nitroimidazole, and co-trimethoprim and sulfamethoxazole. Treatment protocols of any duration were effective.ConclusionAntibiotic prophylaxis obviously decreases the incidence of bacteriuria and middle degree fever but not bacteremia in men with preoperative sterile urine undergoing TPB. A significant decrease in bacteriuria incidence can be achieved with a range of antibiotic agents, including quinolones and co-quinolone and nitroimidazole. Treatment protocols of any duration are effective with no heterogeneity.

Plenty of data and tests suggested that flavonoids have strong physiological and pharmacological activities. In this paper, the absorption, distribution and metabolism of flavonoids in gaster, gut and liver were introduced. The research of absorption, distribution and metabolism on flavonoids will provide theoretical basis for developing new drugs of flavoniods.

OBJECTIVE: To investigate the clinical application and efficacy of ¹²⁵Ⅰ radioactive seeds implantation in the treatment of recurrent salivary gland carcinoma after external radiotherapy. METHODS: From July 2004 to July 2016, 43 cases of recurrent salivary gland carcinoma of the neck after external radiotherapy or surgery combined with external radiotherapy were treated. According to the conventional segmentation radiotherapy for head and neck cancer (once a day, 1.8-2.0 Gy each time, 5 days per week), the cumulative radiation dose of the patients in this group was calculated. In the study, 26 patients received 50-60 Gy, 7 patients received less than 50 Gy, 4 patients received 60-70 Gy, and 6 patients received more than 80 Gy (range: 80-120 Gy). The interval between the last external irradiation and local recurrence was 4-204 months, and the median interval was 48 months. Among them, 25 cases were treated with ¹²⁵Ⅰ radioactive seeds implantation only and 18 cases were treated with ¹²⁵Ⅰ radioactive seeds implantation after operation. The prescription dose was 100-140 Gy. The control rate, survival rate and disease-free survival rate were recorded to evaluate the side effects. RESULTS: The median follow-up time was 27 months (ranging from 2.5 to 149.0 months). Among them, the median follow-up time of adenoid cystic carcinoma patients was 31 months (range: 2.5-112.0 months), and the median follow-up time of mucoepidermoid carcinoma patients was 18 months (range: 5-149 months). The local control rates for 1, 3 and 5 years were 66.5%, 48.8% and 42.7%, respectively. The 1-, 3- and 5- year survival rates were 88.0%, 56.7% and 45.8%, respectively. The disease-free survival rates of 1, 3 and 5 years were 58.3%, 45.4% and 38.1%, respectively. There was no statistically significant difference in local control rate, survival rate, and disease-free survival between the radioactive seeds implantation group and the radioactive seeds implantation group after surgical resection. There were 2 cases of acute radiation reaction Ⅰ/Ⅱ and 3 cases of reaction Ⅲ or above. In the late stage of radiotherapy, there were 8 cases with Ⅰ/Ⅱ grade reaction and 3 cases with Ⅲ grade or above reaction. The incidence of radiation reactions of Grade Ⅲ and above was 7%. CONCLUSION ¹²⁵Ⅰ radioactive seeds implantation provides an alternative method for the treatment of recurrent salivary gland carcinoma after external radiotherapy. The local control rate and survival rate are improved on the premise of low incidence of side effects.

Objective To evaluate the effect of mind mapping on adverse effects caused by medication via patient control alagesia pump(PCA).Methods One hundred and seventy-nine patients with PCA pump after operation were divided into control group(n=90)and observation group(n=89)according to the admission time.The observation group was nursed with mind mapping and the control group with routine method. The incidences of adverse effects caused by medication via PCA pump were compared between the two groups.Result The incidences of adverse effect in the observation group and the control group were 19.1%and 32.2%respectively,with statistical significance(P<0.05).Conclusion Nursing with mind mapping for medication via PAC pump can improve nurses’clinical ability in observation and nursing and therefore effectively prevent and deal with adverse effect caused by medication via PCA pump to relieve patients’pain and improve nursing quality.

Objective:To investigate the role of bone morphogenetic protein 2/7 heterodimer (BMP-2/7)in the osteogenesis of human adipose-derived stem cells (hASCs).Methods:hASCs were exposed to three different treatments in vitro:osteogenic medium with 1 50 μg/L BMP-2/7 (experimental group), osteogenic medium alone (OM group)and proliferation medium (PM group).After 1 ,4 and 7 days of osteogenic induction,the amount of cellular DNA was measured to investigate the cytotoxicity.After 7 and 1 4 days,alkaline phosphatase (ALP)staining and quantification were performed to test the activity of ALP.After 21 and 28 days,the calcification deposition was determined by Alizarin Red S (ARS)stai-ning and quantification.The expressions of the osteoblast-related genes were tested on days 1 ,4,7 and 1 4.In the in vivo study,6 nude mice were used and 4 groups were set and implanted subcutaneously into the back of nude mice:(1 )β-TCP scaffold only (scaffold control group );(2 )β-TCP scaffold with hASCs cultured by PMin vitro for 1 week (PMcontrol group);(3)β-TCP scaffold with hASCs cultured by OM in vitro for 1 week (OM control group);(4)β-TCP scaffold with hASCs cultured by OM with 1 50 μg/L BMP-2/7 in vitro for 1 week (test group).After 4 weeks of implantation,histological staining was performed to evaluate the in vivo osteogenesis of hASCs.Results:After induction for 1 day,there was no significant difference between the experimental group and the PM group on the cellular DNA con-tent (P>0.05 ).After 4 days,the cellular DNA content increased under the stimulation of BMP-2/7 (P<0.05).On day 7,there was no significant difference among the three groups (P>0.05).ALP ac-tivity was higher by the induction of BMP-2/7 than in OMalone and PM(P<0.05).More mineraliza-tion deposition and more expressions of osteoblast-related genes such as Runx2,ALP,COL-1 A1 and OC were determined in the experimental group at different time points (P<0.05).HE staining showed that, in the test group and OM control group,the extracellular matrix (ECM)with eosinophilic staining were observed around hASCs,and newly-formed bone-like tissues could be found in ECM around the scaffold materials.Moreover,compared with the OM control group,more bone-like tissues could be observed in ECMwith typical structure of bone tissue in the test group.Masson’s trichrome staining showed that more expression of collagen could be observed in ECM in the test group compared with the other groups.There was small amount of expression of collagen in the OM and PM control groups.No obvious positive results were found in the scaffold group.Conclusion:BMP-2/7 heterodimer plays a significant role in the osteo-genesis of hASCs and is able to enhance the osteogenic differentiation of hASCs in vitro and in vivo.

Objective To evaluate the safety of coronary intervention using iodixanol in patients with diabetic renal insufficiency.Methods Clinical data of 97 patients with diabetic renal insufficiency undergoing coronary intervention during June 2004 to June 2006 were retrospectively analyzed,50 of them with iodixanol,an iso-osmolar contrast medium (iodixanol group),and 47 with iopromide,a hypotanic contrast medium (iopromide group).Judkin's coronary angiography showed 167 diseased vessels in the patients,65 in anterior descending branches,44 in circumflex branches,and 58 in right coronary arteries. Levels of serum creatinine and blood urea nitrogen were determined before percutaneous coronary intervention (PCI),on the day of the procedure,the 3rd and 7th days after PCI,respectively,as well as radiocontrast media-induced nephropathy (CIN) was observed.Results Totally,192 drug-eluting stents were successfully implanted in 167 diseased vessels,and all patients' angina pectoris symptom disappeared soon after the procedure,with a full success.No acute or subacute stent thrombosis and major adverse cardiac events (MACE) occurred.Two patients (4%) in iodixanol group and 10 (21%) in iopromide group got CIN,with a statistical significance (P

Objective To determine whether the susceptibility to ischemia-reperfusion injury in aged heart is higher than that in adult heart and,if so,to clarify the mechanisms underlying this change.Methods Wister rats(5-or 20-month-old)were randomly divided into 4 groups(6 animals in each group).The rats were subjected to 30 minutes of myocardial ischemia via ligating the left anterior descending coronary artery,followed by 3 hours of reperfusion(Young-MI/R group and Old-MI/R group);A silk suture around the left anterior descending coronary artery was not ligated in young and old rats(Young-sham group and Old-sham group).Myocardial apoptosis was detected by terminal deoxynueleotidyl transferase biotin-d UTP nick end labeling(TUNEL)staining and caspase-3 activity was detected by using a caspase-3 colorimetrie assay.Nitrotyrosine content,a footprint of in vivo ONOO~-formation,and total NO content were determined by ELISA and chemiluminescence method respectively.Results A significantly exacerbated cardiac reperfusion injury was found in Old-MI/R group as evidenced by increased TUNEL positive myocytes[(19.0?2.1)% vs.(14.6?1.7)%],and increased myocardial caspase-3 activity[(436?35)?mool/mg vs.(340?32)?mol/mg] compared with Young-MI/R group(P＜0.05).Aged hearts had a markedly increased basal NOx level compared with young adult hearts.Marked higher myocardial nitrotyrosine content was found in OId-MI/R group[(7.25?0.18)nmol/g]than that in Young-MI/R group[(4.68?0.15)nmol/g] (P＜0.05).Conclusions In aged hearts,high levels of NO might form highly toxie derivant, ONOO~-,and its subsequent nitrified protein.This may attribute to the increased susceptibility of the aged heart to isehemic-reperfusion injury.
