Objective: To investigate the expression of Cyclin E in colorectal carcinoma and its significance.Methods: The Cyclin E expression and the cell proliferation(PI,SPF)in 30 cases of colorectal carcinomas (including tumors and normal tissues distant to the tumors)were respectively assayed with Flow Cytometry (FCM), and the relationships between the Cyclin E expressive rate and clinical pathologic features were compared. Correlaction between the Cyclin E expressive rate and the cell proliferation(PI, SPF) was analyzed too.Results: The Cyclin E positive rate and the cell proliferation in colorectal carcinoma were significantly higher than those of the distal normal tissues. As for the Cyclin E positive rate and the cell proliferation,no significant differences were found among the subgroups divided according to malignance, lymphatic metastasis and the site of tumor. There was a significant correlation between the Cyclin E positive rate and the cell proliferation.Conclusion: The Cyclin E overexpression plays an important role in the onset of colorectal carcinoma.The Cyclin E expressive rate is not consistent with the general clinical pathologic features,but with the cell proliferation. The Cyclin E expressive rate may be one of the potential prognostic indicators in coloretal carcinoma.

Objective To assess the therapeutic efficacy of colonic tumor with targeted microbubbles encapsulated VEGFR2 monoantibody (mAb) combined with ultrasonic abrupted destroy.Methods Seventeen Balb/C nude mice with subcutaneous colonic carcinoma xenografts were divided into three groups:group A (5 mice) underwent contrast-enhanced ultrasonography (CEUS) examination and sham ultrasonic abrupted destroy;group B (6 mice) underwent lipid-microbubbles administration combined with ultrasonic irradiation;group C (6 mice) underwent VEGFR2 monoantibody-loaded microbubbles injection combined with ultrasonic irradiation.Red fluorescent protein(RFP) was labeled to all the nude mice model.Both CEUS and flurography were performed before and one week after abrupted destroy.The size,fluroscent area and fluroscent intensity(FI) and vessel density (VD) of each tumor were measured and compared.Results The parameters of length,fluroseent area,FI and VD of each tumor before abrupted destroy were no significant difference among three groups ( P ＞0.05).Parameters of post-sham ultrasonic abrupted destroy in group A were higher than those before sham ultrasonic abrupted destroy ( P ＜0.05).FI and VD in group B were significantly lower than those after abrupted destroy( P ＜0.05).There were no difference of length,fluroscent area of tumor in group B between pre- and post- ultrasonic abrupted destroy (P ＞0.05).Length,fluroscent area,FI and VD of each tumor in groups C were decreased significantly compared with post ultrasonic abrupted destroy ( P ＜0.01 ).There were significant difference of length,fluroscent area,FI and VD of each tumor among groups after ultrasonic abrupted destroy( P ＜0.05).Conclusions VEGFR2 mAb-loaded lipid microbubble combined with ultrasonic abrupted destroy can improve the therapeutic efficacy of colonic tumor.

Objective To introduce a new method for correcting prominent malar complex deformity. Methods Through an intraoral incision, the highest area of zygomatic body marked preoperatively was grinded. Then an L shape incomplete osteotomy of the zygomatic body was performed with a reciprocating saw, and a complete osteotomy just 1 cm anterior to the articular tubercle of the zygomatic arch was made. Light pressure on the posterior part of the arch produced a greenstick fracture of the anterior osteotomy site, resulting in posterior-inward repositioning of the malar complex. Internal fixation was unnecessary. Results Operative procedures for reductive malar complex plasty were performed in 650 cases, which included 60 males and 590 females whose age ranged from 19 to 39 years.Incisions of all cases healed well. One case had maxillary sinusitis 2 weeks postoperatively, and recovered after 1 week by using antibiotics and drainage. There was 1 case with skin necrosis about 1 cm in diameter in the area of zygomatic body because of local liposuction, and the wound was healed by changing dressing. The forehead wrinkle of one side had disappeared in 1 case 1 week postoperatively, but had recovered 2 weeks later. Postoperative follow-up for 2-24 months showed satisfactory results.Conclusions This modified method has many advantages, such as simplicity, without internal fixation, short operation and recovery time, and little complications. The authors conclude that this technique is an effective and safe method of reduction malarplasty.

Objective To evaluate the application of transrectal ultrasound elastography (TRE) in the detection of prostate cancer(PCa).Methods One hundred and eighteen patients with suspected PCa were enrolled in this study.Each patient underwent transrectal ultrasound (TRUS), TRE and sonography guided prostatic biopsy on the same day.The accuracy rate of PCa detection using TRE were compared with the pathology results.Results Patients with PCa were detected in 62 of the 118 patients,including 48 cases by TRE and 38 cases by TRUS.The sensitivity for TRE (73.6％) was significantly higher than that of TRUS (52.8％) in periurethral zone(P ＜0.05).The sensitivity and specificity for strain ratio(SR) in predicting PCa were 85.7％ and 67.7％ respectively(cut off value：3.6,area under the curve 0.8, P ＜0.01,95％CI [0.68 - 0.92]).Conclusions TRE can detect PCa in the periurethral zone with good accuracy and has potential to increase ultrasound-based PCa detection rate.

BACKGROUND: Whether the differences exist between adipose-derived stem cells isolated from different parts of rats when cultured in vitro has been poorly understood. OBJECTIVE: To compare the growth characteristics and adipogenic ability of adipose-derived stem cells isolated from different parts of rats. METHODS: Freshly isolated adipose-derived stem cells were obtained from 5 mL inguinal groove and greater omentum adipose tissue of F344 rats using type Ⅰ col agenase digestion method. Then, adipose-derived stem cells were counted and cultured in vitro. Morphological and growth characteristics of adipose-derived stem cells derived from the two sites were observed. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay was utilized to examine the doubling time of adipose-derived stem cells from different parts. The passage 2 adipose-derived stem cells were induced adipogenical y. Fourteen days after being induced, the differentiated cells were stained with oil red O and the positive cells were counted. The adipogenic differentiation ability of adipose-derived stem cells from the different parts was assessed. RESULTS AND CONCLUSION: (1) The number of adipose-derived stem cells from the greater omentum fat tissue in the same group was (281±10)×107/L, which was significantly higher than that from the inguinal groove fat tissue [(85±10)×107/L] (P < 0.01). Adipose-derived stem cells from the greater omentum and inguinal groove fat tissue achieved the exponential growth period on days 5 and 6, respectively, and achieved the platform period on days 9 and 10, respectively. The corresponding doubling time was 50 hours and 60 hours, respectively. After being passaged, adipose-derived stem cells grew in fibroblast-like shape actively. The adipogenic differentiation rate of adipose-derived stem cells from the greater omentum fat tissue was higher than that from the inguinal groove fat tissue [(38.90±2.86)% vs. (35.30±3.29)%, P < 0.01]. This shows that the number and the adipogenic differentiation ability of adipose-derived stem cells from different parts of the same F344 rat are different.

Objective To analyze hemolysin and virulence -related genes in incomplete hemolytic Staphylococcus aureus.Methods Fifty strains of incomplete hemolytic Staphylococcus aureus were isolated from patients admitted in the Second Affiliated Hospital of Soochow University during 2013 and 2014, and the isolates with complete hemolytic phenotype were also collected at the same period as the control strains . All the strains were inoculated and subcultured on four kinds of sheep blood agar plates supplied by different manufacturers to compare their hemolytic phenotype .The relative mRNA expressions of hemolysin genes (hla, hlb, hlc, hld) in standard strain, complete and incomplete hemolytic phenotype strains were detected by real-time quantitative polymerase chain reaction (RT-qPCR), and valued by 2 -△△Ct method.t test was used to compare mRNA expressions of hemolysin genes .Western blot was performed to analyze the expression of α-hemolysin.Antibiotic susceptibility test of incomplete hemolytic strains was performed using broth microdilution method.Resistant gene mecA and virulence genes pvl, tst were detected by PCR.Results The steady and hereditary incomplete hemolysis was observed in 50 strains of incomplete hemolytic Staphylococcus aureus on the sheep blood agar plates from different suppliers .Taking mRNA expression of hla, hlb, hlc, hld in standard strain as 1, the relative mRNA expressions of hemolysin genes in incomplete hemolytic strains were 0.02, 7.51, 0.06 and 0.12 respectively, there were statistical differences between standard strain and incomplete hemolytic strains (t =8.46, -56.40, 8.12 and 7.61, all P <0.05).And the expression of α-hemolysin was decreased in incomplete hemolytic strains .All the strains were identified as methicillin resistant Staphylococcus aureus (MRSA).Three strains exhibited different minimum inhibitory concentrations of teicoplanin and linezolid after subcultured , but the differences had no impact on the final results of antibiotic susceptibility test .mecA, pvl and tst genes were positive in incomplete hemolytic strains . Conclusion Staphylococcus aureus with incomplete hemolytic phenotype is methicillin resistant with higher expression of β-hemolysin and lower expressions of α-hemolysin, γ-hemolysin and δ-hemolysin.It carries plv and tst virulence genes and is of high virulence .
