Objective To explore the association between estimated glomerular filtration rate (eGFR) based on creatinine and cystatin C and the SYNTAX score in old patients with coronary heart disease. Methods Two hundred and fifty-six consecutive old patients with coronary heart disease were included in this study. The patients were angiographically diagnosed with coronary heart disease between January 2013 and April 2014 at the Department of Cardiology.eGFR was caculated by using BIS2 equation based on creatinine and cystatin C.SYNTAX score was caculated by SYNTAX score algorithm. Multiple linear regression and ordinal logsitic regreesion was used to analyze the association between eGFR and SYNTAX score. Results In patients with normal of renal function [eGFR≥90 ml/(min·1.73 m2), 110 patients], mild renal insufficiency [60 ml/(min · 1.73 m2) ≤ eGFR<90 ml/(min · 1.73 m2), 98 patients], midrange and severe renal insufficiency[eGFR<60 ml/(min · 1.73 m2), 48 patients], with the decrease in renal function of patients, SYNTAX score increased: (15.42 ± 9.65), (25.24 ± 8.34), (33.73 ± 10.15) scores, P<0.01. eGFR was an independent predictor of SYNTAX score (r=-0.059, P<0.01).eGFR was negatively correlated with SYNTAX score (r=-0.457, P<0.01). Conclusions eGFR is an independent predictor of SYNTAX score and negatively correlated with SYNTAX score in old patients with coronary heart disease. This might be helpful to explain the increased risk of coronary heart disease events and mortality in old patients with renal dysfunction.

Objective:To investigate effects of the modified adhesion retention on the surrounding tissues of dental implant.Methods:182 patients with tooth defects were randomly divided into 2 groups,The patients in control group (n =89) received the traditional retention,in the test group(n =93) received modified adhesion retention.The bone loss at the near and far edges of the implant,alveolar bone height and thickness,the pictorial view of pink esthetic score variables(PES),the modified plaque index(mPLI),the modified sulcus bleeding index (mSBI) and the satisfaction were recorded and compared 1 year after treatment.Results:Compared with control group,the test group showed less bone loss(P＜0.05),more alveolar bone height and thickness(P＜0.05).The satisfaction of the comfort,chewing and language function,retention,esthetics,PES,mPLI and mSBI improved to varying degrees(P＜0.05).Conclusion:The modified adhesion retention is more effective than the traditional retention in stabilizing the bone support of implant and reduce bacterial infection.

Objective:To investigate the effects and mechanisms of anti-cancer by bacailein combined with U0126 on human breast cancer in vitro. Methods: The human breast cancer cell line MCF-7 was treated by baicalein,U0126 and baicalein combined with U0126 respectively. CCK8 assay measured cell proliferation of MCF-7;flow cytometry tested the cell cycle and apoptosis of MCF-7;microscopy observed the amount;TUNEL assay evaluated the apoptosis of MCF-7;Western blot detected the protein level of proliferation and apoptosis related protein;scratch assay measured the ability of migration. Results: Human breast cancer cell line MCF-7 was treated by baicalein or U0126 at different concentration for 24 h, CCK8 assay suggested that both of them can dramatically inhibit MCF-7 proliferation in a dose-dependent way (P<0. 05). Compared to the blank and DMSO groups,the human breast cancer cell line MCF-7 was treated with baicalein for 24 h,the cellular rate at G0-G1 phase increased a lot (91%) (P<0. 05),while the cellular rate at S phase reduced dramatically (P<0. 05),cell apoptosis increased dramatically by microscopy and TUNEL assay(P<0. 05),the level of ERK1/2,CyclinD1 and JNK reduced quickly (P<0. 05). Compared to the baicalein group,MCF-7 was treated by baicalein combined with U0126,the cellular rate at S phase decreased remarkably (P<0. 05),apoptosis was much obvious (P<0. 05),the phosphorylation level of ERK1/2 and JNK reduced a lot (P<0. 05),and the proliferation accelerator CyclinD1 highly decreased (P<0. 05);the scratch assay demonstrated that cell migration was dramatically inhibited when MCF-7 was treated by 20 μmol/L baicalein ( P<0. 05 ) . Conclusion:Both of baicalein and U0126 can inhibit the proliferation and migration,induce the apoptosis of human breast cancer cell line MCF-7 through decreasing the level of ERK, JNK and CyclinD1. Baicalein and U0126 can provide some novel avenues to treat breast cancer in clinic.

OBJECTIVETo introduce and evaluate the technical feasibility and anatomical and functional outcomes of one-stage vaginoplasty with autologous buccal micromucosa combined with acellular allogenic dermis.

METHODSWe retrospectively reviewed our experiences with 17 patients with Mayer- Rokitansky-Kuster-Hauser syndrome treated with primary surgery from September 2010 to April 2013. All patients underwent vaginoplasty with autologous buccal micromucosa combined with acellular allogenic dermis. We describe the details of this technique, observe the time of epithelization and evaluate the long- term anatomical, functional, and sexual outcomes.

RESULTSThe time of epithelization was 13 d (range: 12-15 d). At a mean follow-up of 15 months (range: 12-24 months), the mean postoperative dependence on the vaginal stent was 11.7 ± 1.64 months (range: 9-15 months), the mean depth of the neovagina was (9.0 ± 0.94) cm (range: 7-11 cm), the mean circumference was (12.3 ± 1.36) cm (range: 10.0-14.5 cm) and the mean volume was (105 ± 10) ml (range 85-120 ml). The mean female sexual function index score of the 12 sexually active patients was 29.5 ± 2.6. No spouse reported discomfort during intercourse.

CONCLUSIONSVaginoplasty with autologous buccal micromucosa combined with acellular allogenic dermis is an effective and feasible approach for patients with Mayer-Rokitansky-Kuster-Hauser syndrome. The procedure has satisfactory long-term anatomical and functional results. The use of the acellular allogenic dermis is limited by the high price and the potential infection.

Objective: High mobility group box 3 (HMGB3) plays an important role in the development of various cancer. This study aims to explore whether HMGB3 regulates cervical cancer (CC) progression and elucidate the underlying mechanism. Methods: HMGB3 expression in clinical patients' tumor samples were determined by real-time quantitative polymerase chain reaction (qRT-PCR) and western blot. HMGB3 overexpression/knockdown were used to investigate its function. Cell apoptosis and cycle were detected by Annexin V/PI staining and flow cytometry. In vivo tumor model was made by subcutaneous injection of HeLa cells transfected with shRNAs targeting HMGB3 (shHMGB31) into the flank area of nude mice. Western blot was used to detect the levels of β-catenin, c-Myc, and matrix metalloproteinase-7 (MMP-7) in Hela and CaSki cells transfected with sh-HMGB3 or shRNAs targeting β-catenin. Results: Both messenger RNA and protein levels of HMGB3 were upregulated in CC tissues from patients. High expression level of HMGB3 had positive correlation with serosal invasion, lymph metastasis, and tumor sizes in CC patient. Functional experiments showed that HMGB3 could promote CC cell proliferation both in vitro and in vivo. The expression levels of c-Myc and MMP-7 were increased, resulting in regulating cell apoptosis, cell cycle, and activating Wnt/β-catenin pathway. Conclusions Our data indicated that HMGB3 may serve as an oncoprotein. It could be used as a potential prognostic marker and represent a promising therapeutic strategy for CC treatment.

OBJECTIVE:To provide reference for rational use of antibiotics in the clinic. METHODS:Blood culture positive specimens were collected from our hospital during Jan. 2011-Dec.2016. Distribution of bloodstream infection(BSI)pathogens and drug resistance were analyzed in our hospital retrospectively. RESULTS:During 2011-2016,26 034 blood culture specimens isolat-ed from inpatients of our hospital were examined,including 1 775 positive specimens with positive rate of 6.82%. The specimens mainly came from tumor hematology department(10.65%),neurosurgery department(8.28%)and pediatric department(8.00%). A total of 1 775 strains of pathogens were detected,including 967 strains of Gram-negative bacteria(54.48%)mainly as Escherich-ia coli,Klebsiella pneumoniae,649 strains of Gram-positive bacteria(36.56%)mainly as Coagulase negative Staphylococci, Staphylococcus aureus and 159 strains of fungus(8.96%)mainly as Candida albicans. E. coli and K. pneumoniae were resistant to common antibiotics to different extents,but sensitive to piperacillin sodium and tazobactam sodium,imipenem,meropenem. Aci-netobacter baumanii was highly resistant to enzyme inhibitors,cephalosporins,aminoglycosides,quinolones. Pseudomonas aerugi-nosa was sensitive to third-generation cephalosporins,aminoglycosides and quinolones. S. aureus was highly resistant to penicil-lins,cephalosporins and aminoglycosides. Resistance rate of Coagulase negative Staphylococci to most commonly used antibiotics was higher than 40%. Above two bacteria were sensitive to linezolid and vancomycin with resistance rate of 0. A total of 205 strains of ESBLs-producing E. coli(42.01%),64 strains of ESBLs-producing K. pneumoniae(30.33%)and 31 strains of Methicil-lin-resistant S.aureus(17.61%)were detected.No vancomycin-resistant Enterococcus or vancomycin-resistant S.aureus was detect-ed. CONCLUSIONS:BSI pathogens mainly distribute in tumor hematology department of our hospital. BSI pathogens mainly in-clude Enterobacteriaceae and Staphylococcus,and also involve fungus. The situation of drug resistance and enzyme production are not optimistic.Antibiotics,which are sensitive to the major pathogens,include carbapenems,linezolid and vancomycin.

Objective: To collect preliminary data of normal Chinese female genital appearance, to compare the parameters of Han and Uygur nationality, and to present the preliminary data for normal female external genitalia database. Methods: This study design recruited healthy females referred to the out-patient clinic for physical examination from October 2014 to March 2015 in Xinjiang Petroleum Geological Survey Department Staff Hospital. The recruitment was based on rigid inclusion and exclusion criteria. Demographic data consists of nationality, age, height, weight, marital status, gravidity, parity, vaginal delivery, and intercourse frequency. Anthropometric measurements were taken in 234 females of Han group whereas 278 females of Uygur group. For each individual 16 parameters were measured. The external genitalia appearance in Han and Uygur nationality was compared. The significance of variations in age, height, weight, BMI, gravidity, parity, vaginal delivery and intercourse frequency were analyzed. Results: Primary measurements of Han and Uygur nationality are presented as mean (95% confidence interval). There are many differences in female genital appearance between Han and Uygur nationality. Several parameters were statistically associated with age, BMI, gravidity, parity, vaginal delivery and intercourse frequency. The females with complete labial asymmetry account for 5.6%(13/234) and 5.8%(16/278) in Han and Uygur normal adults, respectively. Conclusions This study presented the external genitalia measurements of normal Chinese female adults in Xinjiang, thus providing the preliminary data for normal female external genitalia database. Females of Han and Uygur nationality have multiple differences in external genitalia appearances. The parameters are associated with age, BMI, gravidity, parity, vaginal delivery, and intercourse frequency. The labial asymmetry is a universal phenomenon.
