RESUMO
BACKGROUND@#The disease burdens for endometrial cancer (EC) vary across different countries and geographical regions and change every year. Herein, we reported the updated results of the Global Burden of Disease Study 2019 on EC with respect to age-standardized incidence and mortality from 1990 to 2019.@*METHODS@#The annual percentage change (APC) of incidence and mortality was evaluated using joinpoint regression analysis to examine the temporal trends during the same timeframe in terms of the global landscape, different sociodemographic indices (SDI), and geographic regions. The relationship between Human Development Index (HDI) and incidence and mortality was additionally explored.@*RESULTS@#The age-standardized incidence rates (ASIRs) revealed a significant average global elevation by 0.5% per year (95% confidence interval [CI], 0.3-0.7; P <0.001). The age-standardized mortality rates (ASMRs), in contrast, fell by an average of 0.8% per year (95% CI, -1.0 to -0.7; P <0.001) worldwide. The ASIRs and ASMRs for EC varied across different SDIs and geographical regions. We noted four temporal trends and a significant reduction by 0.5% per year since 2010 in the ASIR, whereas we detected six consecutively decreasing temporal trends in ASMR during the entire period. Notably, the estimated APCs were significantly positively correlated with HDIs (ρ = 0.22; 95% CI, 0.07-0.35; P = 0.003) with regard to incident cases in 2019.@*CONCLUSIONS@#Incidence rates for EC reflected a significant increase overall (although we observed a decline since 2010), and the death rates declined consecutively from 1990 to 2019. We posit that more precise strategies can be tailored and then implemented based on the distinct age-standardized incidence and mortality burden in different geographical areas.

Objective·To study the change of circulating endothelial progenitor cells (cEPCs) in acute ischemic stroke (AIS) patients within one week after attack,and the correlation of cEPCs with the prognosis.Methods·Ninty-two patients with AIS (AIS group) and 20 patients with risk factors (Risk group) were recruited.The proportion of cEPCs (CD34TKDR+ cells) in peripheral blood mononuclear cells of AIS patients was measured by flow cytometry (FCM) on the first day of admission and the seventh day after attack.Functional recovery was assessed by modified Rankin Scale (mRS) on the 90th day after onset.The cEPCs percentages of AIS patients with different mRS were compared to analyze their correlation.Results·Compared with Risk group,cEPCs percentage of AIS group on the 1st day of admission was lower (P=0.016).In AIS group,compared with poor prognosis group (mRS＞2),eEPCs percentage of good prognosis group on the 7th day after onset (mRS ≤ 2) elevates (P=0.002).The result of multiple linear regression showed that cEPCs percentage on the 7th day after onset was positively correlated with mRS on the 90th day (t=4.608,P=0.011).Conclusion·The percentage of cEPCs in peripheral blood of AIS patients decreases significantly during the acute phase.The percentage on the 7th day after onset is correlated with prognosis of AIS patients.
RESUMO
Objective · To study the metabolite profiles on patients of ischemic stroke using metabonomics approach. Methods · The serum samples from the 29 patients with ischemic stroke and 31 healthy controls were analyzed by gas chromatography time-of-flight mass spectrometry (GC-TOFMS) coupled multi-dimensional statistical methods to find differential metabolites in two groups. Results · Orthogonal partial least squares analysis (OPLS) model was generated based on identified metabolites and shown clear discrimination from patients and healthy controls. Some serum metabolite levels were significantly altered in patients. Six up-regulated metabolites included γ- aminobutyric acid, glutaric acid, glyceric acid, gluconic acid, lactobionic acid, and cholesterol, and nineteen down-regulated metabolites included citric acid, aconitic acid, malic acid, succinic acid, β-alanine, and glycerol-3-phosphate. Conclusion · Amino acid metabolism, glycometabolism and tricarboxylic acid (TCA) cycle are disturbed in patient of ischemic stroke. The metabonomic approach has great potential to understand the underlying mechanisms of stroke in ischemic patients.

Objective To evaluate the value of whole genome amplification (WGA) combined with array comparative genomic hybridization (aCGH) in prenatal diagnosis. Methods Array CGH were performed by the DNA of 18 prenatal specimens , which were amplified by WGA because of the low DNA yield. Result 3 of the 18 fetuses were 45, X0 and 9 of 15 fetuses with normal aCGH results showed healthy outcome. Conclusion It’ s feasible for prenatal diagnosis using WGA combined with aCGH which not only can shorten the reporting time but also keep the sensitivity and accuracy of detection.
RESUMO
ObjectiveTo evaluate and compare the prognosis of idiopathic macular holes (IMH) and traumatic macular holes (TMH) treated by pars plana vitrectomy (PPV). Methods The clinical data of 72 IMH eyes and 55 TMH eyes, which were treated by PPV between November 2001 and December 2007,were retrospectively reviewed. The visual outcomes and macular anatomic closure were evaluated, and their relationships with prognostic factors including the size of macular hole (MH), preoperative visual acuity (VA) and duration of disease were analyzed. Results The closure rate of IMH (100. 0%) was significant higher than that of TMH (85.5%) (P=0. 001). The postoperative VA of IMH and TMH were (0. 25±0.02) and (0. 21±0. 21) respectively, both significantly increased compare to their preoperative VA (t=-6. 841, -4. 093; P=0.000). VA-increased IMH and TMH eyes had same VA (χ2=3. 651, P=0.07).Pre-PPV VA≥0. 1 IMH eyes had better outcomes than Pre-PPV VA＜0. 1 IMH eyes (χ2 = 12.04, P=0. 001), while Pre-PPV VA had no effects on TMH outcomes (χ2=0. 371, P=0. 486). IMH eyes with small holes had better outcomes (t=2. 476, P=0. 016), and TMH eyes with small holes had better closure (t= -4. 042, P＜0. 001). The duration of disease had no significant influence on TMH visual (χ2=0. 704,P = 0. 401 ) and anatomic (χ2 = 0. 166, P= 0. 684) outcomes. Conclusions PPV is an effective treatment for MH. The closure rate of IMH is higher than that of TMH. The diameter of MH and preoperative VA are major factors for IMH outcomes, and the duration of disease and preoperative VA have no effects on postoperative VA in TMH.
RESUMO
BACKGROUND: Mini-screw anchorage is an innovation technique applied in the orthodontic field, expanding the treatment ability of orthodontic appliance. Accurate of mini-screw insertion in the target position is a clinical problem which making orthodontist trouble in this technique application. OBJECTIVE: To introduce a kind of three dimensional guide of mini-screw used as anchorage in orthodontic treatment and to evaluate the positioning accuracy. DESIGN, TIME AND SE'I-rlNG: A contrast study was performed at the Department of Orthodontics, Capital Medical University from April to October 2005. PARTICIPANTS: Twenty cases (40 mini-screws) of maxillary critical anchorage requisition were considered as the experimental group, and 15 cases (30 mini-screws) who were not treated with surgical guide were considered as the control group. METHODS: Self-made stent was used as a positioning guide for implantation of mini-screw anchorage between the roots of upper second bicuspid and first molar. Thereafter, the position was measured. MAIN OUTCOME MEASURES: The vertical distance from measure points to the reference middle line were measured. RESULTS: In 40 mini-screws inserted with the aid of surgical guide, the average survival time of mini-screw as anchorage was 10.3 months, 2 were lost, and the success rate was 95%. The average survival time of 30 mini-screws in the control group was 9 months, 9 were loss, and the success rate was 70%. The positioning measurement showed that deviation of mini-screw was not found in the experimental group, but it was found in the control group. CONCLUSION: By aid of surgical guide splint, mini-scraw can be inserted correctly into the target region.
