Objective To investigate the group B streptococcus( GBS)colonization rate and the relationship between vaginal colonization of GBS and the pregnancy outcome. Methods Five hundred and twenty cases pregnant women were selected as our subjects. Microbiological culture was used for culture of GBS in 1 / 3 of vagina and rectus before delivery,other samples from different sites after delivery(including neonatal throat,ear and placenta). Results (1)The GBS carrier rate in 520 pregnant women was 10. 19%(53 / 520). (2)GBS carrier rate in neonatal was 8. 85%(46 / 520). The carrier rate of neonatal whose mothers also carried GBS was 22. 64%(12 / 53),higher than that of non-carrier mothers(7. 28%(34 / 467),χ2 = 8. 192,P < 0. 05) . The rate of pneumonia and the upper respiratory tract infection of neonatal with GBS-carrier-mother were 20. 75%(11 / 53)and 18. 87%(10 / 53),higher than that of non-carrier mothers(8. 57%(40 / 467)and 4. 71%(22 / 467)). The pneumonia rate and upper respiratory tract infection of GBS positive neonatal were 21. 73%(10 / 46)and 19. 56%(9 / 46),higher than GBS negative one(8. 65%(41 / 474);4. 85%(23 / 474)). and there were significant differences(χ2 = 8. 121,15. 717;P < 0. 05).(3)The incidence of intrauterine infection and fetal distress of neonatal with GBS( + )mother were 47. 17%(25 / 53),15. 09%(8 / 53),significantly higher than that of negative(7. 07%(33 / 467),4. 71%(22 / 467)),and the differences were statistically significant( χ2= 77. 248,9. 440;P < 0. 05). But there were the similar incidence in term of premature rupture of fetal membranes,premature occurrence rate between GBS positive and negative mothers( 28. 30%( 15 / 53 ) vs. 28. 48%(133 / 467;3. 77%(2 / 53)vs. 2. 36%(11 / 467);χ2 = 0. 001,0. 393;P > 0. 05). The rate of GBS positive with mycotic vaginitis,placenta previa ratio were 39. 62%(21 / 53),7. 55%(4 / 53),higher than that of GBS negative one(20. 56%(96 / 467),1. 93%(9 / 467)),and the differences were statistically significant(χ2= 9. 922,6. 168,P < 0. 05). Conclusion Maternal GBS carrier at 35 - 37 weeks of gestation can lead to adverse pregnancy outcome by increasing intrauterine infection fetal distress and neonatal infections. Screening of GBS should be performed routinely in late gestation.

The studying in the department of medical imaging is a vital part of the standardized training for resident,which is important to make appropriate and efficient training schedule for the improvement of residents' diagnostic capability.At present,the standardized training for resident doctors of traditional Chinese medicine is lack of enough attention and effective teaching plan.In view of the current situation of poor imaging basis,short rotation time and the lack of educational programs in clinical doctors of traditional Chinese medicine,we achieved significant training effect through a series of systematic training programs such as using the theory of teaching,PPT teaching,informatization teaching,individuation teaching and so on.

[Objective] To detect the expression levels of connexin43(Cx43),P-gp and COX-2 in bone marrow of patients with acute leukemia (AL),and investigate their relationship with the pathogenesis,prognosis and resistance of this condition.[Methods]Using SYBR green real-time quantitativereverse transcription polymerase chain reaction (SYBR-RT-PCR),the expression of Cx43,P-gp and COX-2 mRNA were detected in 77 AL patients at different phases,including 36 initially-treated,20 complete-remission (CR)and 20 relapsed.A follow-up was done in those initially lreated.[Results]Expression levels of Cx43,P-gp and COX-2 mRNA from initially-treated were 0.52±0.57,1.42 ±1.06,1.14±0.95;those from relapse AL patients were 0.20±0.40,2.29 ±1.11,1.69±0.81,respectively,those from CR patients were 0.95±0.37,0.93±-0.73,0.79±0.58,respectively,those from normal patients were 1.16 ±0.67,0.86±0.63,0.61±0.57.Expression levels of Cx43 mRNA in initially-treated and relapse AL patients were significantly lower than those in normal patients and CR patients(initially-treated P were 0.001,0.005;relapse patients were P＜0.001),while the comparison between normal patients and CR patients showed no statistical significance(P=0.185).Cx43mRNA expression level was negatively correlated with P-gp and COX-2 mRNA,and a negative correlation was noted of both two expressions in initially-treated and relapse groups (Cx43 mRNA and P-gp mRNA r were -0.471,-0.362,-0.526;Cx43 mRNA and COX-2 mRNA r were -0.479,-0.344,-0.471).A follow-up of four months was conducted in 36 initially-treated patients,eight of them died.The expression Cx43 in those who died was lower than that who survived.The difference was significant(t=2.16,P=0.042).[Conclusion] Cx43mRNA expression levels of initially-treated and relapse AL patients were lower than those in normal patients and CR patients,P-gp and COX-2 mRNA expression levels of initially-treated and relapse AL patients were higher than those in normal patients and CR patients.Cx43 expre-ssion probably is a favorable prognostic factor.Cx43 is participation in the genesis,development and drug resistance of AL.

Objective_To study the effect of human insulin on cell cycle progression and apoptosis of rat liver cell line BRL-3A in vitro.Methods_MTT method was used to observe the effect of insulin on cell activity, and flow cytometry was used to detect cell apoptosis and cell cycle.qRT-PCR was used to evaluate the expression of related genes.Results_Human insulin induced the proliferation of BRL-3A cells in a dose-dependent manner ( P<0.05 or P<0.01);After 3 days treated by human insulin (500 nmol/L), the proportion of cells in G0/G1 phases re-markably decreased (P<0.05).Moreover, pro-apoptotic BAX was down-regulated (P<0.05), while cell prolif-eration-related gene CCNA2 was up-regulated (P<0.05).Conclusions_Human insulin may inhibit the apoptosis of BRL-3 A cell line and induce proliferation due to the down-regulated expression of BAX and up-regulated expres-sion of CCNA2 .

BACKGROUND:The effects of engineered bone scaffold containing seeding cels with different shapes to repair bone defect are varied, while the loaded cellquantity is the important factor influencing the curative effect, but which is rarely reported. OBJECTIVE:By preparing self-made corrugated tissue-engineered bone scaffold and other three forms of bone tissue engineering scaffolds, to study the quantity of loaded cels on different scaffolds and osteogenesis of corrugated tissue-engineered bone scaffold so as to discuss the advantages and features of self-made corrugated tissue-engineered bone scaffold. METHODS: (1) Experimentin vitro: There were four kinds of scaffolds with the same volume and samples: calcium phosphate cement (CPC) corrugated surface scaffold group, smooth surface scaffold group, cylindrical scaffold group and porous cylindrical scaffold with holow tubes group, in which the latter three groups are control ones. A certain volume with same density of rabbit bone marrow mesenchymal stem cels (BMSCs) suspension after osteogenesis induction was seeded onto the scaffolds. After incubation, culture, digestion and colection, cellquantity was counted, absorbance value was finaly detected and cellactivity was proofed by alkaline phosphatase and alizarin red staining. (2) Experimentin vivo: New Zealand rabbits were randomly and equaly divided into recombinant human bone morphogenetic protein-2 (rhBMP-2)/CPC/BMSCs corrugated scaffold group, pure CPC corrugated scaffold group and cancelous bone implant group. Three kinds of scaffold implants with the same volume were inserted into the area between rabbit’s L5, 6 transverse processes bilateraly. At 4, 8, 12 weeks postoperatively, gross and histological observation was performed. RESULTS AND CONCLUSION:(1)Experimentin vitro: The drip of cellsuspension steadily stayed on the surface of corrugated scaffold because of corrugated shape groove and the surface tension of the liquid. The amount of cels per sample digested down from the CPC corrugated surface scaffold was significantly more than that from the other three groups (P < 0.05), while the absorbance values did not differ (P > 0.05). (2) Experimentin vivo: At each time point the osteogenesis quantity of rhBMP-2/CPC/BMSCs corrugated scaffold group was more than that of the pure CPC corrugated scaffold group (P < 0.05), while there was no difference from the cancelous bone implant group (P > 0.05). These findings indicate that the characteristics of the self-made corrugated engineered bone scaffold are beneficial to seed cellloading, which supports a large number of osteogenesis and provides feasibility to promote the healing of segmental bone defects.

Objective To investigate the expression of CXC chemokine receptor 1 (CXCR1) and CXC chemokine receptor 2 (CXCR2) in triplenegative breast cancer (TNBC) and its significance.Methods The EnVision immunohistochemistry system was used to detect the expression of CXCR1 and CXCR2 in 28 specimens from normal tissues adjacent to breast cancer,30 specimens of invasive ductal carcinoma not otherwise specified (IDC-NOS),and 34 TNBC specimens.The relationship between the expression of CXCR1 and CXCR2,and clinical pathological features was analyzed.Results In the adjacent normal tissues of breast cancer,the positive expression rates of CXCR 1 and CXCR2 were 89.3％ and 92.9％,respectively;CXCR1 and CXCR2 expression displayed no significant association with clinicopathological parameters such as age,tumor size,or Scarff-Bloom-Richardson (SBR) score.The positive expression rates of CXCR1 and CXCR2 were 63.3％ and 60.0％,respectively,in the IDC-NOS samples and 23.5％ and 35.3％,respectively,in the TNBC samples.There was a positive correlation between CXCR1 and CXCR2 expression in the TNBC samples (r =0.606,P ＜ 0.001).Conclusion Correlation of CXCR1 and CXCR2 expression with sample type was strong in adjacent normal tissues,moderate in IDC-NOS samples,and low in TNBC samples.CXCR1 expression was positively correlated with CXCR2 expression in all sample types.The expression of CXCR1 or CXCR2 was closely related to the development and promotion of TNBC.

Objective To analyze and discuss the correlations between different areas of corneal thickness and ICare rebound tonometer ( RBT ) .Methods Totals of 108 volunteers were selected as the subjects.Corneal thicknesses (central cornea, 2mm distance of corneal limbus nasal side and temporal side,) were measured by using optical coherence tomography ( OCT) , and intraocular pressure of different corneal areas were measured with RBT.The correlation of corneal thickness and intraocular pressure in different corneal zones were analyzed by Pearson correlation analysis.Results Thicknesses in central cornea,2 mm distance of corneal limbus nasal side and temporal side were (527.84 ±32.93), (551.31 ±35.40) and (533.91 ±34.42)μm, respectively.Numbers of IOP were (16.39 ±5.31), (16.37 ±5.48) and (16.44 ±5.72) mmHg, respectively.Central corneal (r=0.319,P<0.01), nasal side (r=0.267,P<0.05),temporal side (r=0.299, P <0.02 ), positive correlation was found between corneal thickness and intraocular pressure. Conclusions Corneal thickness of different areas will affect measurement results of intraocular pressures by using ICare rebound tonometer.
