Objective To evaluate the clinical effect of breast implant on congenital mammary dysplasia with mild pigeon chest deformity. Methods From January 2003 to July 2009,10 cases of female mammary dysplasia (between 20 to 31 years of age) underwent breast implant surgery. Subpectoral placement and transaxillary incision were selected. The surgeon marked the range of the operation on the skin, made a 3-4 cm incision in the armpit, separated the tissue until the pectoral lateral margin, cut the pecto-ralis fascia and bluntly created a suitable pocket under the pectoralis major for the implant. After the implant was placed in the pocket, the incision was closed. Results Ten cases of breast implant surgery did not pose the complications of local skin necrosis, infection, implant shift, heart and lungs dysfunction after one year follow-up. The appearance of anterior chest wall deformity was markedly improved. Conclusions The application of breast implant surgery in the treatment of congenital mammary dysplasia with mild pigeon chest deformity should be promoted, because of the double surgical effect of easy performing, minimal surgical damage, perfect breast shape and concealed deformity.

Objective To investigate and evaluate the clinical signiifcance of lfexible ureteroscopy in computed tomography urography negative patients with upper urinary tract hematuria. To improve the diagnostic rate of patients with upper urinary tract hematuria. Methods We retrospectively reviewed the cases of 10 computed tomography urography negative patients with upper urinary tract hematuria. The age ranges from 38 to 75 years old, and the average of them is 45.2 years old. The patients consist of 7 male patients and 3 female patients. Among them, 4 cases were on the left upper urinary tract cases, 6 cases were right upper urinary tract. All patients received lfexible ureteroscopy to conifrm the diagnosis and take the relevant treatment. Results In the total of 10 patients, 3 patients (30%) were diagnosed with tumors of renal pelvis, a renal arteriovenous ifstula was found in 1 case (10%), 3 patients (30%) were considered non-specific inflammation, other 3 patients (30%) had no obvious abnormalities. Conclusions Flexible ureteroscopy has significantly clinical diagnosis in computed tomography urography negative patients with upper urinary tract hematuria.

Objective To evaluate the effectiveness of ultrasound (US) volume navigation technology in guiding the lum?bar transforaminal puncture with full?endoscopic technique through posterolateral approach. Methods From June 2011 to June 2013, 60 patients (37 males and 23 females;mean age:32.9 years) with single?level lumbar disc herniation who had undergone lumbar transforaminal puncture with full?endoscopic technique through posterolateral approach were enrolled in this retrospective study, and they were randomly divided into 2 groups according to whether the assistance of ultrasound volume navigation technolo?gy was used. They received the minimally invasive surgery on L4, 5 (47 cases) and L5S1 (13 cases). In the US?guidance group (29 cas?es), ultrasound volume navigation was used to guide puncture process, and in the C?arm guided group (31 cases), C?arm was ap?plied to guide the puncture process The total puncture time and C?arm fluoroscopy times were recorded. Parameters including Os?westry disability index (ODI) and visual analogue scale (VAS) were selected to evaluate the clinical efficacy. Results Patients had no obvious discomfort during the puncture procedure and no postoperative complications. In US?guidance group, the preopera?tive time was 13.7 ± 2.1 min (range, 11-16 min), and the whole process took 20.6 ± 3.1 min (range, 16-28 min), while the average time of C?arm exposure were 4.9 ± 0.8 times (range, 4-7 times). In C?arm guided group, the average time for puncture procedure was 27.9±1.7 min (range, 25-32 min), and the average times of C?arm exposure were 14.3±1.2 times (range, 13-17 times). There were significant differences between two groups. Compared with C?arm guided group, US?guidance group had the same accuracy rate of puncture (the puncture needles all reached the target area), but the fluoroscopy times and puncture timewere decreased sig?nificantly. There’s no significant difference among the pre and postoperative ODI and VAS indexes. Patients were followed?up at 3 months and 1 year postoperation. The mean follow?up period was 16.4 months (range, 12-26 months). The ODI score of the US?guidance group were 72.9%±5.9%, 17.1%±3.6%and 15.9%±3.3%before operation, 3 months postoperation and 1 year postopera?tion respectively. The ODI score of the C?arm guided group were 73.2%±4.9%, 17.3%±3.3%and 16.1%±2.9%respectively. The VAS were 7.4±0.9, 2.2±0.7 and 1.9±0.8 in US?guidance group, and were 7.2±0.9, 2.1±0.7, 1.8±0.8 in C?arm guided group. Con?clusion The ultrasound volume navigation can guide the lumbar transforaminal puncture with full?endoscopic technique through posterolateral approach accurately, reducing the puncture time and the amount of X?ray radiation significantly. Its puncture accura?cy and efficacy have no significant differences, which could be broadly used in clinical application.

A Cleanert Alumina-N-SPE column (0.5 g/6 mL) chromatograpy with 5 mL of chloroform-methanol (7: 3) as eluent, instead of aluminum oxide column (100-200 mesh, 5 g, 1 cm) chromatograpy eluted successively with chloroform and the chloroform-methanol (7:3) (20 mL each), was applied to enrich matrine and oxymatrine in Sophora flavescens. Also, the optimization of the HPLC determination conditions with acetonitrile-ethanol absolute-3% phosphoric acid solution (84: 6: 10) as mobile phase, instead of acetonitrile-ethanol absolute -3% Phosphoric acid solution (80: 10: 10) recorded in Chinese Pharmacopoeia 2010 Edition, was more suitable for determination of matrine and oxymatrine in S. flavescens. This method has advantage of reducing sample handling time and solvent volume and increasing the accuracy and feasibility, which can simplify the procedure for determination of matrine and oxymatrine in S. flavescens.

Objective To investigate the expression of FBP1 in human renal clear cell carcinoma and paracancerous tissue and its effect and clinical significance in the carcinogenesis,progression and prognosis of renal cancer.Methods The paraffin sections from 118 patients with renal clear cell carcinoma treated by surgical resection and fresh specimens from 40 patients with renal clear cell carcinoma were selected.The expressions of FBP1 protein and mRNA in renal cancer and paracancerous tissues(negative incisal edge) were detected by adopting the immunohistochemistry(IHC),Western blot and RT-PCR.Its correlation with clinicopathologic characteristics and prognosis of the patients was analyzed.Results The IHC result,found that strong positive expression of FBP1 protein could be seen in 78.81％ (93/118) of cancer-adjacent tissues,while only 39.83％ (47/118) of renal cancer tissues had positive expression.Western blot found that the expression positive rate of FBP1 in renal cancer tissue was significantly decreased compared with corresponding cancer-adjacent tissues (P＜0.01).RT-PCR found that the FBP1mRAN expression level in cancer-adjacent tissues was also significantly higher than that in renal cancer tissue(P＜0.05).The FBP1 low expression was significantly correlated with the clinical stage,pathologic grade,UISS risk coefficient and recurrence(P＜0.05),and had no relation with the age,gender,symptoms,tumor size,location,tumor necrosis,vascular invasion and adrenal involvement(P＞0.05).The 5-year survival rate in renal cancer patients with FBP1 positive expression was higher than that in the patients with FBP1 negative expression(P＜0.05).Conclusion FBP1 and protein are lowly expressed in renal cancer tissue,are correlated with occurrence and development of renal cancer,and may become one of candidate markers of renal cancer prognosis.

OBJECTIVE: To study the effects of myo-inositol and luteolin on human lung cancer A549 cells and explore the possible mechanisms. METHODS: A549 cells were treated with different concentrations of myo-inositol and luteolin, either alone or in combination, and the cell viability was examined using MTT assay. A549 cells and human bronchial epithelial Beas-2B cells were treated for 48 h with 10 mmol/L myo-inositol and 20 μmol/L luteolin, alone or in combination, and the cell proliferation was detected using MTT assay; the colony formation and migration of the cells were examined with colony formation assay and wound healing assay, respectively. The protein expression levels in A549 cells were detected using Western blotting. RESULTS: Both myo-inositol and luteolin could dose-dependently inhibit the viability of A549 cells. Treatments with 10 mmol/L myo-inositol, 20 μmol/L luteolin, and both for 48 h caused significant reduction in the cell viability (92%, 83% and 70% of the control level, respectively) and colony number (79%, 73% and 43%, respectively), and significantly lowered the wound closure rate (24.61%, 13.08% and 8.65%, respectively, as compared with 29.99% in the control group). Similar treatments with myoinositol and luteolin alone or in combination produced no significant inhibitory effect on the growth, colony formation or migration of Beas-2B cells. The expressions of p-PDK1 and p-Akt in myo-inositol-treated A549 cells and the expression of pPDK1 in luteolin-treated cells were significantly decreased ( < 0.05), and the decrements were more obvious in the combined treatment group ( < 0.05). CONCLUSIONS Luteolin combined with myo-inositol can selectively inhibit the proliferation and migration of A549 cells, and these effects are probably mediated, at least in part, by suppressing the activation of PDK1 and Akt.

This study aimed to investigate the prevalence and molecular characteristics of Listeria monocytogenes in cooked products in Zigong City, China. The overall occurrence of the L. monocytogenes in the ready-to-eat (RTE) shops and mutton restaurants surveyed was 16.2% (141/873). An occurrence of 13.5% was observed in RTE pork, 6.5% in RTE vegetables, and more than 24.0% in either cooked mutton or cooked haggis. Serotype 1/2b (45.4%), 1/2a (33.3%), and 1/2c (14.2%) were the predominant types. By comparing the clonal complexes (CCs) based on multilocus sequence typing (MLST) of the L. monocytogenes from cooked foods in Zigong City and 33 listeriosis cases from different districts of China, CC87, CC9, CC8, and CC3 were showed to be prevalent in cooked products and CC87 and CC3 were the first two frequent types in the 33 clinic-source strains. All CC87 stains harbored the newly reported Listeria pathogenicity island 4 (LIPI-4) gene fragment ptsA, and all CC3 strains possessed the Listeria pathogenicity island 3 (LIPI-3) gene fragment llsX. These may increase the occurrence of the strains belonging to CC87 and CC3 in listeriosis cases in China and also underline the risk of infection owing to the consumption of the cooked products from Zigong. ST619 (serotype 1/2b) harbored both llsX and ptsA, indicating a potential hypervirulent sequence type in Zigong.
