Objective To analyze the clinical outcomes of using double-circle incision combined with the dermal bra technique for the correction of simple breast ptosis.Methods From March 2010 to December 2014,88 patients underwent breast ptosis correction using the technique,among which 52 cases were classified into mild ptosis,27 moderate ptosis,and 9 severe ptosis.According to the extent of ptosis,varying size of the dermal bra were designed,and the mammary glandular flap was rotated,suspended and fixed onto the pectoralis fascia.For patients with insufficient size of the dermal bra,the polypropylene mesh was used to assist glandular suspension and fixation.Follow-up duration was between 3 to 24 months,and the surgical effect was evaluated from the following aspects:wound healing,breast sensory,shape,and texture,etc.Results The 4 cases (4.5％) had hematoma,and 3 cases (3.4％) suffered from poor wound healing.No case of fat liquefaction,necrosis of the nipple and areola complex,sensory disorder of NAC,or secondary ptosis was examined.Mammary contour was slightly rigid in the early postoperative period but gradually becoming natural with soft texture 3 months postoperatively.Conclusions Double-circle incision combined with the dermal technique is worth spreading in the clinical practice of breast ptosis correction for its satisfactory outcomes and low incidence of complications.

OBJECTIVETo explore the feasibility of the transdiferentiation of human breast adipose-derived stem cells (hbASCs) into mammary epithelial-like cells after co-culturing in Transwell in vitro.

METHODSThe third passage hbASC and the HBL-100 cell line were co-cultured in a Transwell culture system for 15 days. The hbASCs were observed and identified by inverted phase contrast microscope and transmission electron microscopy, and immunocytochemistry staining in the induced and control groups.

RESULTSBoth the third passage hbASCs and the HBL-100 cell line cells could adhere and grow rapidly after co-culture in the Transwell system. After co-culture for 15 days, the morphology of some induced hbASCs changed into epithelial-like cells. Some induced hbASCs showed positive expression of CK18, CK19 by immunocytochemistry staining, and typical epithelium cells with microvilli, desmosomes and tonofilaments observed under TEM. The positive rate of CK18 and CK19 was (24.4 +/- 12.0)% and (21.6 +/- 16.4)% in experimental group, and (1.8 +/- 1.7)% and (1.1 +/- 0.6)% in control group.

CONCLUSIONThe data suggests that hbASCs may have the potential to transdifferentiate into human mammary epithelial-like cells after co-culturing in Transwell in vitro.

Objective To analyse the relationship between lymphatic vessels invasion and clinical pathological features of papillary thyroid carcinoma ( PTC ) .Methods The expressions of D2-40 and CK19 were examined in the 104 specimens of PTC using immunohistochemical staining with combined monoclonal antibodies and cocktail double enzyme labeled antibody( D2-40/CK19) stainings.The two methods were compared in the diagnosis of PTC metastasis, and the factors affecting lymphatic vessels formation were analyzed.Results The positive rate of lymphatic vessels invasion was 37.5%(39/104) by using immunohistochemical staining with combined monoclonal antibodies and 53.8%( 56/104 ) by cocktail double enzyme labeled antibody ( D2-40/CK19 ) staining ( P<0.05).The lymph node metastasis rate was 83.9%(47/56) in the group with lymphatic vessels invasion, significantly higher than that without invasion 22.9%(11/48, P<0.01).The age of patients, diameter of primary tumor were the influence factors of lymphatic vessels invasion in PTC patients(P<0.05 and P=0.063).Conclusion Cocktail double enzyme labeled antibody ( D2-40/CK19 ) staining is a better method to detect lymphatic vessels invasion in PTC than immunohistochemical staining with combined monoclonal antibodies.

Objective To review the clinical data of reduction mammoplasty by central pedicle technique,and to summarize all kinds of the complications to modify the technique for improvement of long term aesthetic effects.Methods The postoperative complications were analyzd and then an approach was used to investigate the pattern of the blood supply and the nerve distribution of breast.Based on the anatomical study,a modified double-circle reduction mammoplasty technique was designed to treat patients with hypertrophical breasts. Results With a follow-up for 3 months to 3 years,the patients who underwent this modified central pedicle technique,had an invisible scar,good projection,the better shape of breast and preserved their sensation of nipple-areola complex.Conclusions Modified central pedicle technique is a safe and reliable technique,especially ideal for Chinese women.The blood supply is rich and the sensation of nipple-areola complex is preserved.The fixation of the gland tissue is more important than the dermal-bra.

Objective To measure serum and tissue levels of soluble syndecan-1 (SDC1) in patients with cutaneous squamous cell carcinoma (CSCC),and to explore the relationship between the expression of SDC1 and clinicopathologic features of CSCC as well as between the serum and tissue levels of SDC 1.Methods An immunohistochemical study was performed to measure SDC 1 expression in the epidermis of lesional specimens from 93 patients with CSCC and normal skin specimens from 30 healthy human controls,and enzyme-linked immunosorbent assay (ELISA) to detect serum levels of soluble SDC1 in 81 patients with CSCC and 30 healthy human controls.Results The expression of SDC1 was significantly lower in CSCC tissues than in normal skin tissues (Z=3.85,P＜ 0.01).The expression intensity of SDC 1 decreased with the increase in tumor thickness but with the decrease in degree of differentiation of CSCC (x2 =11.66,12.51 respectively,both P ＜ 0.01).Furthermore,the expression of SDC1 was significantly lower in lesional tissues of CSCC with lymph node metastasis than in those without (Z =2.20,P ＜ 0.05).As ELISA showed,serum levels of soluble SDC1 were significantly higher in patients with CSCC than in healthy controls (Z=4.12,P＜ 0.01),and gradually increased with the increase in tumor thickness and with advancing clinical stages of CSCC.In addition,serum levels of SDC1 were significantly up-regulated in patients with invasive CSCC compared with those with CSCC in situ (Z =3.02,P ＜ 0.01),but were not significantly different among patients with invasive CSCC at different degrees of differentiation (P ＞ 0.05).CSCC patients with lymphatic metastasis showed significantly higher serum levels of SDC1 compared with those without (Z =5.30,P ＜ 0.01).The serum levels of soluble SDC1 were significantly negatively correlated with its tissue levels in CSCC patients (rs =-0.625,P ＜ 0.01).Receiver operating characteristic (ROC) curve analysis showed that the best cutoff point of serum SDC 1 levels was 65.5 μg/L for the diagnosis of lymphatic metastasis,with the sensitivity,specificity and area under the curve (AUC) being 73.7％,87.1％ and 0.904 (0.840-0.968) respectively.Conclusion The downregulated tissue expression but up-regulated serum levels of SDC 1 may be associated with the invasiveness of CSCC,and elevated serum SDC 1 levels are somewhat valuable to the diagnosis of lymphatic metastasis.

Objective:To explore the effect of mild cognitive impairment on the subjective well-being of the elderly and the mediating role of self-efficacy in it. To provide an effective basis for health management and clinical intervention in the elderly with mild cognitive impairment.Methods:A total of 164 patients with mild cognitive impairment from December 2018 to June 2019 were surveyed by the General Self-efficacy Scale, the Montreal Cognitive Assessment Scale, and the Memorial University of Newfoundland Scale of Happiness Scale.Results:The overall score of self-efficacy was 21.41±3.98, and subjective well-being was 26.44±7.35. There was a positive correlation among cognitive function, self-efficacy and subjective well-being, except that there was no significant correlation between self-efficacy and cognitive function( r values were 0.263-0.687, P<0.01). Self-efficacy played a part in mediating between cognitive function and subjective well-being in patients with mild cognitive impairment, accounting for 37.8% of the total effect. Conclusions:Mild cognitive impairment can also have a negative impact on the subjective well-being of the elderly. Among them, self-efficacy plays a particularly important role in mediating. Interventions about self-efficacy on the elderly with mild cognitive impairment may have more significant effects.

Objective To evaluate the diagnostic performance of osteopontin (OPN)for ovarian cancer.Methods Wanfang, CQVIP and CNKI were retrieved to identify eligible studies on diagnostic value of OPN for ovarian cancer that published be-fore May,2014.The quality of the studies was evaluated by QUADAS tools.The diagnostic sensitivity,specificity,negative and positive likelihood ratios and diagnostic odds ratio (DOR)were pooled by random-effects models.The overall diagnostic performance was estimated by summary receiver operating characteristic (SROC)curves approaches.Results Six studies met the included criteria.The summary estimates for OPN in the diagnosis of ovarian cancer in the studies included were as follows:sensitivity 0.83 [(95% confidence interval(CI):0.78~0.87)],specificity 0.91 (95% CI,0.88~0.94),positive likelihood ratio 9.00 (95% CI,5.91~13.71),negative likelihood ratio 0.19 (95% CI,0.15~0.25),and DOR 47.58 (95%CI,27.93~81.05).The area under curve (AUC)for OPN was 0.87 with Q value of 0.80.Conclusion OPN has high diag-nostic value for ovarian cancer.

Objective: To investigate the clinical characteristics and prognosis of adult acute myeloid leukemia (AML) with TLS-ERG fusion gene positive. Methods: Adult two AML patients with TLS-ERG fusion gene positive in the First Affiliated Hospital of Zhengzhou University in January 2017 and March 2018, respectively were enrolled, and their clinical characteristics and prognosis were analyzed. Results: Both patients with TLS-ERG fusion gene positive were males. According to morphology classification, the first case was classified to AML-M₅, and the other one was AML-M₄. Both patients' immunophenotypic features showed CD56 expression, and CD25 was expressed in the first patient simultaneously. Both patients were treated with induction and consolidated intensive therapy based on Chinese guidelines for diagnosis and treatment of adult AML (not acute promyelocytic leukemia) and the guidelines for diagnosis and treatment of AML (relapse/refractory) in China. The first patient died 11 months after diagnosis, and the second patient remained in remission until the end of follow-up in February 2019 (12 months after diagnosis). Conclusion TLS-ERG fusion gene has low incidence rate, high recurrence rate, poor reinduction effect, poor prognosis and short survival time in adult AML.
