Method The convenience sampling method was used to investigate the status of empowerment and illness perception among 102 patients with type 2 diabetes mellitus from October 2014 to July 2015, followed by analyzing the association between the two variables. Results The total score of empowerment was (4.00 ± 0.65), and the total score of illness perception was (38.00 ± 2 . 33 ) . The empowerment was positively correlated with illness perception ( P < 0 . 001 ) . The empowerment was positively correlated with the timeline, personal control, treatment control, illness concern and illness comprehensibility, respectively (all P<0.001). Conclusions The empowerment of patients with type 2 diabetes mellitus is at a high level, and positively correlated with illness perception, more pronounced chronic nature, the better personal control and treatment control, a higher degree of concern about the disease and better personal understanding of the illness contributed to a higher degree of empowerment. Medical staff should evaluate the illness perception of the patients with type 2 diabetes mellitus regularly in the daily work so as to improve the illness perception , improve their empowerment and promote the patients′quality of life eventually.

Salvia miltorrhiza Bge. is a perennial deciduous flowering plant. Its medicinal root and rhizomes part is widely used in the treatment of various diseases. In this study, bioinformatics analysis was performed to identify 4832 genome SSR loci with length longer than or equal to 40 bp from the draft genome assembly of S. miltorrhiza. The re-sults showed that the dinucleotide repeat motifs and trinucleotide repeat motifs constitute the main types of genome SSR loci, accounting for 37.3% and 61.3% respectively. SSR types enriched with A/T bases showed significantly higher abundance than other types, including AT/TA AAT/ATT, ATA/TAT, TAA/TTA, accounting for 30.5%, 21.6%, 17.1%, 20.4% of the total number of SSR loci, respectively. 1079 primer pairs were designed for these genome SSR loci. These primers can be used for genomic diversity analysis, genetic map construction, genetic marker screening. These data could lay the foundation for population genetics and genomics research of S. miltorrhiza.

Objective To explore the effect of dexmedetomidine on phosphoinositide 3-kinase/protein kinase B (PI3K/Akt ) pathway in hippocampus of propofol anesthetized neonatal rats. Methods Eighty Sprague-Dawley male rats,aged 7 days,weighing 10-1 5 g,were randomly divided into 8 groups (n= 10 each):normal saline group (group N),DMSO group (group D),intralipid group (group I),propofol group (group P),dexmedetomidine 25 μg/kg,50 μg/kg and 75 μg/kg +propofol 100 mg/kg groups (groups PD25 ,PD50 and PD7 5 ),LY294002 25 μg + dexmedetomidine 75μg/kg + propofol 100 mg/kg group (group LYPD).The hippocampus of rats in all groups were taken 2 h after the animals fully awake.The ultrastructure of hippocampal neurons was observed by transmission electron microscope.The pAkt-(ser473 )protein and Akt protein in the hippocampus were evaluated by Western blot analysis.Results There was no significant difference in the expression of Akt protein among the eight groups.Compared with group N,the expression of pAkt (ser473)protein was significantly down-regulated in groups P,PD25 ,PD50 ,PD7 5 and LYPD (P <0.05).Compared with group P,the expression of pAkt (ser473)protein was increased significantly in groups PD7 5 and LYPD (P <0.05).Compared with group PD7 5 ,the expression of pAkt (ser473) protein was significantly down-regulated in group LYPD (P <0.05 ).The structure of hippocampal neurons was normal in groups N,I and D.Nuclear nuclei swelling,chromatin decreasing and mito-chondrion vacuolar degeneration were observed in group P while improved gradually with dexmedeto-midine in a dose-dependent manner in groups PD25 ,PD50 and PD7 5 .Neurons karyopyknosis,partial dissolution of nuclear membrane,chromatin condensation,mitochondria vacuolar degeneration were observed in group LYPD.Conclusion Dexmedetomidine pretreatment provides neuroprotection against propofol-induced hippocampal destruction by preserving PI3K/Akt pathway activity in the de-veloping brains.

Objective To investigate the early diagnostic value of cornel confocal microscopy for the screening of small neuropathy in elderly patients with type 2 diabetic mellitus.Methods In the prospective study,96 elderly patients with diabetes as study group and 46 patients with non-diabetes as the control group were continuously collected from our hospital endocrinology and ophthalmology out patients during May 2014 to February 2016.The 96 cases of type 2 diabetes were subdivided into 47 patients with diabetic peripheral neuropathy (DPN)and 47 patients with nowdiabetic peripheral neuropathy(non DPN).Results The diabetes course was shorter in non-DPN group than in DPN group(P=0.000).The levels of glycosylated hemoglobin and urine albumin were lower in the nonDPN than in the DPN(P =0.072,0.007,respectively).The corneal nerve fiber density was lower in the DPN group than in NDPN group (P =0.000).Corneal nerve fiber density was higher in control group than in DPN and NDPN group.The differences in number of corneal nerve fibers showed no statistical significance between DPN and NDPN group (x2 =2.391,P =0.314).But the number of corneal nerve fibers was significant less in DPN and NDPN group than in control group(x2 =16.014,P =0.000).The negative correlation was found between the course of disease and corneal fibrous density by using single factor linear regression analysis.The number of corneal nerve fibers was lower in smoking group than in non-smoking group(P=0.003).The multiple linear regression analysis showed that duration of diabetes was a risk factor for diabetic neuropathy.Conclusions In some elderly diabetic patients with non-neuropathy,corneal nerve fiber density and number have been significantly decreased before nerve conductive velocity is reduced.Therefore,corneal confocal microscopy can be used to detect and diagnose small diabetic neuropathy in elderly patients with diabetes mellitus.

Objective To evaluate the effect of dexmedetomidine on the activity of glycogen synthase kinase-3 beta (GSK-3β) during propofol-induced apoptosis in hippocampal nerve cells of newborn rats.Methods Sixty male 7-day-old Sprague-Dawley rats,weighing 10-15 g,were divided into 6 groups (n=10 each) using a random number table:normal saline group (group NS),fat emulsion group (group F),propofol group (group P) and different doses of dexmedetomindine groups (group D25,group D50 and group D75).Normal saline and fat emulsion 100 μl were injected intraperitoneally in group NS and group F,respectively.In group P,propofol 50 mg/kg was intraperitoneally injected,and an increment of propofol 50 mg/kg was added after righting reflex completely recovered,with the total amount of 100 mg/kg.In group D25,group D50 and group D75,dexmedetomidine 25,50 and 75 μg/kg were intraperitoneally injected,respectively,and 30 min later propofol 100 mg/kg was administered.At 2 h after emergence,the rats were sacrificed,their brains were removed for determination of apoptosis in hippocampal nerve cells (by TUNEL),and the hippocampi were isolated for detection of the expression of GSK-3β and phosphorylated GSK-3β (p-GSK-3β) by Western blot analysis.The apoptosis index (AI) and ratio of p-GSK-3β/GSK-3β were calculated.Results Compared with group NS,AI was significantly increased,the expression of p-GSK-3β was down-regulated,and the p-GSK-3β/GSK-3β ratio was decreased in P,D25,D50 and D75 groups (P＜0.05).Compared with group P,AI was significantly decreased,the expression of p-GSK-3β was up-regulated,and the p-GSK-3β/GSK-3β ratio was increased in D25,D50 and D75 groups (P＜0.05).Compared with group D25,AI was significantly decreased (P＜0.05),and no significant change was found in the expression of p-GSK-3β or ratio of p-GSK-3β/GSK-3β in D50 and D75 groups (P＞0.05).Compared with group D50,AI was significantly decreased (P＜0.05),and no significant change was found in the expression of p-GSK-3β or ratio of p-GSK-3β/GSK-3β in group D75 (P＞0.05).Conclusion The mechanism by which dexmedetomidine attenuates propofol-induced apoptosis in hippocampal nerve cells may be related to inhibition of GSK-3β activity in newborn rats.

Objective To evaluate the effect of morphine on the growth of subcutaneous tumor of human gastric cancer cells in nude mice.Methods Thirty SPF male BALB/C nude mice,aged 4-5 weeks,weighing 15-20 g,in which the model of subcutaneous tumor of human gastric cancer cell line MGC-803 was established,were randomly divided into 3 groups (n=10 each) using a random number table:control group (group C),normal saline group (group N),and morphine group (group M).The mice in group C received no treatment.Morphine 20 mg/kg was intraperitoneally injected once a day for 14 consecutive days in group M,while normal saline 1.5 ml/kg was given instead of morphine in group N.The caliper was used to measure the tumor size every 2 days starting from 3 days after beginning of administration,and the relative tumor volume was calculated.The nude mice were sacrificed on 15th day,and the tumor tissues were obtained for determination of nuclear factor-kappa B activity and Bcl-2 and Bax protein and mRNA expression by real-time reverse transcriptase polymerase chain reaction and Western blot.Results Compared with group C,the relative tumor volume was significantly decreased,the activity of nuclear factor-kappa B in tumor tissues was significantly decreased,the expression of Bcl-2 protein and mRNA was significantly down-regulated,and the expression of Bax protein and mRNA was significantly up-regulated at each time point in group M (P＜0.05),and no significant change was found in each parameter mentioned above in group N (P＞0.05).Conclusion Morphine can inhibit the growth of subcutaneous tumor of human gastric cancer cells in nude mice,and the mechanism is associated with promotion of apoptosis in tumor cells.
