Objective To study the clinical efficacy and safety of Rosiglitazone (RSG) combined with insulin in treatment of elderly type 2 diabetes mellitus (type 2 DM) that had poor response to insulin treatment. Methods 68 cases of elderly type 2 DM patients with poor response to insulin treatment were randomly divided into experimental group and control group.The control group was treated with proper dose of insulin,and the experimental group were administered RSG 4mg/day plus insulin for 20 weeks. 4 weeks and 20 weeks after treatment FBC, PBC, HbA1C, UAER of 24 hrs, daily changes of insulin dosage and side-effect of the medicine were observed. Results In the experimental group the levels of FBG and PBG decreased in 4 weeks(P

Objective To investigate the mechanism that cause allelic dropout of amelogenin gene on X chromosome(Amel-X)when using routine Sullivan106/112 bp primer set in sex identification and discuss its influence on the forensic sex identification and the clinical diagnosis.Methods Amel-X dropout was validated with Sullivan212/218 bp and Haas-Rochholz80/83 bp primer sets.Amplification of amelogenin gene was used to analyze dropout of the Amex-X followed by sequencin.Results Sullivan212/218 bp and Hgas-Rochholz80/83 bp primer sets could be used to identify gender correctly.Three types of point mntation were observed in the forward primer binding region of the Sullivan106/112 bp primer set by sequencing in the lost Amel-X,including single point mutation at 2nd and 13th sites,respectively,and heterozygous multiple point mutations at 2nd and 13th sites.Conclusions Point mutation in the primer binding region may result in a failure to amplify amelogenin allele and thus lead to a null allele.This finding should be mid attention to because it may interfere with the sex identification.

Objective:To investigation the veracity of orientation on modified upright lateral cephalometric radiographs. Methods:Fifty upright lateral cephalometric radiographs were analysed randomly.Twenty-three subjects,who had standard radiographs, were taken with modified technique. The chracterics both of radiographs were compared. Results:The orientations of porion?FH plane and the superimpositions of left and right gonion point on modified standard radiographs were more veracity. Conclusion:The veracity of orientation on upright lateral cephalometric radiographs can be improved.

Objective To compare the difference of ultrasound-guided anterior sciatic nerve block by multiple injection and single injection.Methods Among 90 patients undergoing lower limb operation,aged 18-68 years old,47 patients were males and 43 patients were females,all falling into ASA Ⅰ-Ⅲ.The patients were randomized to ultrasound-guided anterior sciatic nerve block by multiple injection (group M,n=45) single injection (group S,n=45).Local anesthetic of 0.5% ropivacaine hydrochloride 20 ml was used.The width,thickness and depth of sciatic nerve and blocking performance time were recorded.Sensory and motor blockade on the operated limb were evaluated every 10 minutes after injection of local anesthetic for 30 minutes and complications were observed in two groups.Results The width,thinkness and depth of sciatic nerve on the ultrasound screen were not statistically significant in the two groups.The performance time of group M was longer than that of group S (P<0.05).The proportion of patients with sensory blockade of each nerve significantly differed between the two groups: for superficial peroneal nerve at 10,20,and 30 minutes,for the sural nerve at 20,30 minutes,for the tibial nerve at 30 minutes,that of group M was higher than that of group S (P<0.05).A significantly greater rate of motor blockade was observed for the dorsal flexion of foot and toes extension in group M than that of group S at 30 minutes (P<0.05).The complications of nausea,vomitting and tinnitus were not different in two groups.Conclusion Multiple injection needs more operation time compared with single injection,but its onset time of sensory and motor blockade is quicker,the complications were not different.

Background Chinese dietary reference intakes for calcium are largely based on foreign studies.We undertook metaregression to estimate calcium requirements for Chinese adults derived from calcium balance data in Chinese adults.Methods We searched PubMed,Cochrane CENTRAL,and SinoMed from inception to March 5,2014,by using a structured search strategy.The bibliographies of any relevant papers and journals were also screened for potentially eligible studies.We extracted a standardized data set from studies in Chinese adults that reported calcium balance data.The relationship between calcium intake and output was examined by an individual participant data (IPD) and aggregate data (AD) meta-regression.Results We identified 11 metabolic studies in Chinese adults within 18-60 years of age.One hundred and forty-one IPD (n=35) expressed as mg/d,127 IPD (n=32) expressed as mg·kg body wt-1·d-1,and 44 AD (n=132) expressed as mg/d were collected.The models predicted a neutral calcium balance (defined as calcium output (Y) equal to calcium intake (C)) at intakes of 460 mg/d (Y=0.60C+183.98) and 8.27 mg·kg body wt-1·d-1 (Y=0.60C+3.33)for IPD,or 409 mg/d (Y=0.66C+139.00) for AD.Calcium requirements at upper intakes were higher than that at lower intakes in all these models.Conclusion Calcium requirement for Chinese adults 18-60 years of age approximately ranges between 400 mg/d and 500 mg/d when consuming traditional plant-based Chinese diets.

Objective: To observe the effects of Radix Glycyrrhizae polysaccharide on regulatory T cells (Treg) in spleen and lymphocyte transformation ratio in tumor-bearing mice so as to explore the mechanisms of its immunoregulatory function. Methods: Fifty BALB/c mice were randomly divided into normal group, untreated group, cyclophosphamide group, Radix Glycyrrhizae polysaccharide group and Radix Glycyrrhizae polysaccharide plus cyclophosphamide group. Except normal group, mice were subcutaneously implanted H22 tumor cells in the right axillary region. After 24 h, mice in normal and untreated group were subcutaneously injected with physiological saline, while mice in the cyclophosphamide group were intraperitoneally injected with cyclophosphamide and mice in Radix Glycyrrhizae polysaccharide group were subcutaneously injected with polysaccharide. Fourteen days later, Treg cells of spleen were detected by flow cytometry and lymphocyte transformation ratio was detected by methyl thiazolyl tetrazolium method. Results: The proportion of Treg cells was significantly higher in the untreated group than in the normal group, and was lower in the Radix Glycyrrhizae polysaccharide group than in the untreated group (P

Objective To explore the effect of continuous aspiration of subglottic secretion at different negative pressure levels on mechanical ventilation. Methods Toally 142 patients were randomized by way of lottery into the control group (n=70) and the experiment group ( n = 72 ): the control group received continuous negative pressure aspiration of subglottic secretion at a negative pressure of 60 mmHg while the experiment group did 30~40 mmHg for grade I of the sticky secretion , 40~60 mmHg for gradeⅡ~Ⅲof the sticky secretion, respectively. The two groups were compared in terms of the rate of ventilator associated pneumonia (VAP), airway mucosal injury and cough. Result There was no significant difference in the rate of ventilator associated pneumonia (P>0.05), but the rates of airway mucosal injury and cough were lower in the experiment group than those of the control group (P < 0.05). Conclusion It is reasonable to choose different negative pressure levels based on stickiness of the secretions for mechanical ventilation, for it can prevent the ventilator associated pneumonia and airway mucosal injury.
