Objective To explore the influencing factors of glycemic variability in 217 cases of hospitalized patients with type 2 diabetes. Meth-ods A total of 217 cases of hospitalized patients with type 2 diabetes,whom received continuous glucose monitoring from January 2013 to Janu-ary 2016,were enrolled for the study. The evaluation variables of glycemic variability included mean amplitude of glycemic excursion(MAGE) and standard deviation of blood glucose(SDBG). Results The difference of glycemic variability was compared by gender,age,diabetic duration, HbA1c,BMI. The values of MAGE and SDBG in females were higher than those in males(P<0.05). There was no significant difference between various age groups and various diabetic duration. The level of glycemic variability increased gradually with the extension of HbA 1c(P<0.05). The level of glycemic variability increased gradually with the extension of body mass index(BMI)(P<0.05). Logistic regression analysis showed that gender(OR=0.67,P=0.02),HbA1c(OR=0.8,P=0.02),diastolic blood pressure(OR=0.9,P=0.03),triglycerides(OR=4.6,P=0.007),cholesterol(OR=0.6,P=0.007). HDL-C(OR=0.09,P=0.006)were significant influencing factors of glycemic variability in hospital-ized patients with type 2 diabetes. Conclusion Gender,HbA1c,BMI,and blood fat are significant influencing factors of glycemic variability while age and duration are not related to the glycemic variability in hospitalized patients with type 2 diabetes.

Panax ginseng C. A. Meyer (P. ginseng) has been used as traditional medicine in Asian countries for more than 2,000 years. P. ginseng contains many active components such as ginsenosides, peptides, essential oil and polysaccharides, among which, P. ginseng polysaccharides were reported to have immunomodulating, anti-cancer, anti-adhesive and antioxidant activities. For better understanding of the structures and biological activities of all the ginseng polysaccharides, here the recent research achievements were reviewed. This review would be helpful for the relevant researchers to get useful information.

Objective To investigate the role of Staphylococcus aureus enterotoxin B (SEB) in non-IgE mediated activation of mast cells (MCs) by in vitro co-culture of laboratory of allergic disease 2 (LAD2) cells and SEB.Methods The LAD2 cells were incubated with SEB at different concentrations of 0.01,0.1,1,10 and 100 μg/ml,A23187 positive control and negative control separately for 30 minutes.Then,effects of SEB on the morphology of MCs were observed by using a light microscope,and culture supernatants of the above incubation systems were collected.The concentration of tryptase released from MCs was analyzed by enzymatic activity assay,and the level of histamine was detected by enzyme-linked immunosorbent assay (ELISA).Results After 30-minute co-culture of LAD2 cells and SEB,MCs showed larger size,obscure boundaries,increased number of protuberances on the cell surface and decreased refractivity,with a radial burr fin-like appearance.After 30-minute co-culture of LAD2 cells and SEB at different concentrations of 0.01,0.1,1,10 and 100 μg/ml,the concentrations of tryptase in the culture supematants were 4.116 ± 0.651,5.344 ± 0.874,3.806 ± 0.459,1.309 ± 0.247,0.310 ± 0.199 ng/ml respectively.Additionally,the tryptase levels were significantly higher in the 0.01-,0.1-,1-μg/ml SEB groups than in the negative control group(1.538 ± 0.490,all P ＜ 0.05),and gradually decreased along with the increase of SEB concentrations.The histamine levels in the 0.01-,0.1-,1-,10-and 100-μg/ml SEB groups were 242.409 ± 63.915,522.491 ± 73.466,550.926 ± 84.466,334.397 ± 33.640,226.527 ± 5.678 ng/ml respectively.In the 0.01-,0.1-,1-μg/ml SEB groups,the levels of histamine released from MCs were gradually increased along with the increase of SEB concentrations,and were significantly higher than those in the negative control group (146.436 ± 3.100,all P ＜ 0.05).However,with the continued increase of SEB concentrations,the histamine levels gradually decreased.Conclusion SEB can directly activate MCs by a non-IgE mediated mechanism,followed by morphologic changes of MCs and release of tryptase and histamine.

Objective To examine the expressions of serum growth hormone (ghrelin), leptin (LP), in sulin-like growth factor-1 (IGF-1) and insulin-like growth factor binding protein-3 (IGFBP3) in children with id-iopathic short stature (ISS), and their significance. Methods A total of 40 patients with ISS were selected from May. 2012 to Oct. 2014 in Fuyang Maternal and Child Health Hospital, while a total of 40 children in good health were selected as the control group. Serum ghrelin and LP levels were measured by ELISA. Serum IGF-1 and IGF-BP3 levels were detected by chemiluminescence immune assay. Results were analyzed statistically. Results The height, weight, BMI, GH, serum LP, IGF-1, and IGFBP3 levels in the observation group were significantly lower than those in the control group, while serum ghrelin expression level was significantly higher than that in the control group(P<0.05). The correlation analysis showed that ghrelin and LP were negatively correlated(r=-0.611, P<0.01), ghrelin and IGF-1 levels were negatively correlated(r=-0.520, P<0.05), Ghrelin and IGFBP3 were pos-itively correlated (r=0.586, P<0.01), IGF-1 and IGFBP3 was negatively correlated (r=-0.576, P<0.01), and LP and IGFBP3 were negatively correlated (r=-0.609, P<0.01). Conclusions It shows that ghrelin, LP, IGF-1, and IGFBP3 levels in children with ISS are related to growth hormone secretion status. The interactions between ghre-lin and insulin-like growth factor axis regulate growth and development of children.

Objective To evaluate the clinical significance of positive peritoneal cytology in patients with endometrial cancer.Methods The records of 315 patients with endometrial cancer who were operated at Cancer Hospital, Fudan University between January 1996 and December 2008 were reviewed.Peritoneal cytology were performed and diagnosed in all patients.Factors related with peritoneal cytology were analyzed by correlation analysis.Log-rank test and Cox regression test was used for the analysis of prognosis,respectively.Results (1) Peritoneal cytology were positive in 30 (9.5%) patients.Positive peritoneal cytology was associated with pathological subtype ( P = 0.013 ), stage ( P = 0.000 ), myometrial invasion ( P =0.012), lymph-vascular space invasion ( P = 0.012 ), serosal involvement ( P = 0.004 ), cervical involvement ( P = 0.016), adnexal involvement ( P = 0.000), and omental involvement ( P = 0.000), with no association with grade ( P = 0.152 ) and lymph node metastasis ( P = 0.066 ).( 2 ) Three-year overall survival (OS) and progression-free survival(PFS) were 93.0% and 85.5% ,respectively.Positive peritoneal cytology, surgical stage, pathological subtype, myometrial invasion, grade, and lymph-vascular space invasion were significantly associated with worse prognosis by univariate analysis ( P ＜ 0.05 ), while only surgical-pathology stage and myometrial invasion were independent prognostic factors by multivariate analysis ( P ＜ 0.05 ).For 30 cases with positive peritoneal cytology, the patients with no high risk factors shown significantly prognoses better than those with any risk factors.The results shown that for patients with late stage (stage Ⅲ - Ⅳ ) endometrial cancer with positive peritoneal cytology was significantly associated with the worse OS and PFS by multivariate analysis ( P = 0.006).Conclusions Positive peritoneal cytology was associated with serosal involvement, cervical involvement, adnexal involvement, omental involvement, and late stage.Therefore, peritoneal cytology should be performed and reported separately as a part of full surgical staging procedure.

Objective To report the first case of cutaneous type adult T-cell leukemia/lymphoma(cATLL) in China. Methods The skin lesion was examined by histopathology and direct immunofluorescence (DIF), and the immunophenotype was also studied. ELISA and Western blot were used to test the serum antibodies to HTLV-Ⅰ, and HTLV-Ⅰproviral DNA of lymphoid cells was detected by PCR. Results The patient had polymorphic skin lesions including papules, plaques, and bullae with tense or flaccid walls. Histopathogical examination showed subepidermal bullae, and there were small-to-medium-sized atypical lymphoid cell infiltrations in the dermal papilla in the bottom, and border of the bulla. CD45+ and CD45RO+ staining, and negative DIF were observed in the atypical lymphoid cells. The serum antibodies to HTLV-Ⅰ, and proviral DNA of HTLV-Ⅰin the blood lymphoid cells were detected. The patient died with a disease course of one year and ten months. Conclusion ATLL is not extremely rare in China, and cATLL may also exist.
