ObjectiveTo evaluate the impact of hyperglycemia in patients admitted to medical intensive care units(MICU)on their prognosis.MethodsMedical records of 1016 patients,including 126 cases of known diabetes,359 cases with newly diagnoses hyperglycemia,and 531 normoglycemic cases,admitted to MICU in Wuhan University People's Hospital during September 2006 to September 2007 were reviewed to compare their case-fatality,length of hospital stay,length of MICU stay,mechanical ventilation,blood transfusion and antibiotics use.ResultsIn.hospital case-fatality was 22.8%(82/359)in patients with newly-diagnosed hyperglycemia.significantly higher than that in patients with known diabetes of 12.7% (16/126)and in normoglyeemic cases of 5.1%(27/531)(P＜0.01),and that Was higher in those with diabetes than those with normal blood glucose level(P=0.002).Proportions of patients who needed mechanical ventilation,blood transfusion,antibiotics use was higher in newly diagnosed hyperglycemia group than those in the other two groups.ConclusionsHyperglycemia represents an important mal'ker of poor clinical outcomes and mortality in patients admitted tO MICU.Patients with newly diagnosed hyperglycemia had a significantly higher case-fatality and poorer outcomes than those with known diabetes or normoglyeemia.

Objective To evaluate the effect of comprehensive intervention measures on preventing and controlling surgical site infection (SSI)in patients undergoing total abdominal hysterectomy.Methods Patients undergoing total abdominal hysterectomy in a hospital between January 2011 and December 2014 were investigated retrospec-tively,patients in 2011 were as control group,from January 2012,a prospective monitoring on SSI was initiated, comprehensive intervention measures were taken,patients between January 2012 and December 2014 were as inter-vention group,SSI before and after the intervention was compared.Results A total of 1 052 patients undergoing to-tal abdominal hysterectomy were investigated,267 cases were monitored before intervention,25 patients (9.36%) developed healthcare-associated infection (HAI),12(4.49%)of whom were with SSI;785 cases were monitored af-ter intervention,13 (1 .66%)of whom were with SSI,incidence of SSI in 2012,2013,and 2014 were 2.31 %, 1 .89%,and 0.77% respectively,there was a decreasing tendency(χ2 =7.30,P <0.01 ).Conclusion Prospective monitoring on SSI and comprehensive intervention can reduce the incidence of SSI in patients undergoing total abdominal hysterectomy.

Aim To clarify the regulation role of ca-thepsin B ( Cat B ) in cell proliferation and apoptosis induced by SAHA in ER-positive breast cancer cell line MCF-7.Methods MTT was used to screen the optimal concentration and treatment time of SAHA . The expression levels of related proteins were deter-mined by ELISA , and the morphological changes were observed through time-lapse live cell imaging acquisi-tion.Cell viability and apoptosis assay in MCF-7 cells were assessed by Muse Cell Analyzer with SAHA and /or Cystatin C treatment .Results MTT assay showed that the anti-tumor efficacy of SAHA was significant . The optimal concentration and treatment time were 10μmol? L-1 and 24 h respectively . ELISA assay showed that SAHA could induce expression of Cat B in MCF-7 cells.Real-time live-cell imaging experiments demonstrated that the combination treatment of Cystatin C and SAHA significantly resumed the inhibitory effect caused by SAHA alone .Cytology test showed that SA-HA alone obviously depressed the cell viability and in-duced apoptosis . However , the effect was reversed with the combination of Cystatin C .Conclusion Cat B plays an important role in apoptosis induced by SAHA in ER +breast cancer cells MCF-7.

Objective To assess the effects of caffeine use in apnea of prematurity (AOP) in the early stage (caffeine was used within 3 days after birth) versus late stage (caffeine was used 4 to 10 days after birth ) . Methods Medline, Science Direct, Elsevier, Embase, CBMdisc and Wanfang databases were retrieved to incorporate studies that met the inclusion criteria. The retrieval time limit was from the establishment of the databases to November, 2015. References that were in line with the inclusion criteria were selected and relevant conference data were collected by manual retrieval. Two researchers conducted meta-analysis using software RevMan 5. 2 after independent data selection, information extraction and quality evaluation according to the inclusion and exclusion criteria. Results One randomized controlled trial and four retrospective cohort studies were included. A total of 59 288 patients were involved. Meta-analysis suggested that, compared with caffeine use in the late stage, the early stage group showed significant lower incidence ( P < 0. 05 ) of mortality, bronchopulmonary dysplasia, intraventricular hemorrhage, periventricular leukomalacia, retinopathy of prematurity and surgical intervention of patent ductus arteriosus. No significant difference (OR = 0. 98, 95% CI 0. 72 - 1. 33, P = 0. 881) was observed between the 2 groups in terms of the incidence of necrotic enterocolitis. Conclusions Patients with AOP should start caffeine treatment as early as possible, which significantly decreases mortality rate and the occurrence of other complications with little adverse reactions and good clinical tolerance.

Objective To observe the regulatory effects of the preventive acupuncture and moxibustion at Guanyuan (RN4) points in ovariectomized rats, and discuss the mechanism of preventive acupuncture and moxibustion on hyoathalamus-pituitary-ovary (HPO) axis. Methods Totally 48 female SD rats were divided into 5 groups, including normal group, sham operation group, ovariectomized rats group, preventive acupuncture group and preventive moxibustion group. Except normal group and sham operation group, rats were ovariectomized after preventive acupuncture and preventive moxibustion for 30 d in corresponding groups. ELISA was used to determine the levels of E2, ER, GnRH, FSH and LH in the tissues including hypophysis, hypothalamus and uterus. Results Compared with the normal group, E2, ER and GnRH level in the tissue of the model group was significantly lower (P<0.01), the levels of FSH and LH increased obviously (P<0.01). Compared with the model group, E2, ER and GnRH level of preventive acupuncture group and preventive moxibustion group increased in different degree (P<0.05). FSH and LH level reduced in different degree (P <0.05). There was no obvious difference between preventive acupuncture and preventive moxibustion group (P>0.05). Conclusions The preventive acupuncture and preventive moxibustion at Guanyuan (RN4) has benign modulation to disordered HPO axis of ovariectomized rats. The ability of preventive acupuncture and preventive moxibustion are almost the same.

To investigate the relationship of the expressions of matrix metalloproteinases(MMPs) and tissue inhibitor of metalloproteinase (TIMP) with metastasis and prognosis in colorectal cancer. Using S P immunohistochemistry method to detect the expressions of MMPs and TIMP in 41 cases of colorectal cancer. The expression levels were analyzed quantitatively by computer image analysis system. The results showed that the expression of MMP 2,MMp 9 and TIMP 1 was higher than those in normal epithelial mucosa. In the cases with metastasis to lymph node, the expressions of MMP 2 and MMP 9 TIMP 1 were significantly higher than that of cases without metastasis.The high expressions of the three factors are closely correlated with the progression and poor prognosis of colorectal cancer. It suggested that expressions of MMPs and TIMP are closely related with metastasis and prognosis in colorectal cancer.

In order to study mechanical stress on root from orthodontic tooth movement by sliding mechanics, a 3-dimensional finite element model incorporating all layers of a human mandibular dental arch with orthodontic appliance has been developed to simulate mechanical stress on root from the orthodontic tooth movement. Simulated orthodontic force of 2 N at 0, 30 and 45 degree from the horizontal axis was applied to the crown of the teeth. The finite element analysis showed when orthodontic forces were applied to the tooth, the stress was mainly concentrated at the neck of the tooth decreasing uniformly to the apex and crown. The highest stress on the root was 0.621 N/mm(2) for cervical margin of the canine, and 0.114 N/mm(2) for apical region of the canine. The top of canine crown showed the largest amount of displacement (2.417 microm), while the lowest amount of displacement was located at the apical region of canine (0.043 microm). In conclusion, this model might enable one to simulate orthodontic tooth movements clinically. Sliding force at 2 N is ideal to ensure the bodily orthodontic tooth movement. The highest stress concentration in the roots was always localized at the cervical margin when orthodontic force of 2 N at 0, 30 and 45 degree from the horizontal axis, so there may be the same risk of root resorption when orthodontic force of 2 N at 0, 30 and 45 degree was used in clinic cases.
