Objective To analyze the antimicrobial resistance and the profile of pathogens from lower respiratory tract infections in pediatric in patients. Methods Sputum bacterial isolates were identified by an automated biochemical identification system. Antimicrobial resistance was detected by an automated drug susceptibility detection system and the disc diffusion method. The β-lactamases was tested by the nitrocefin disc detection method. Results Five hundred and eighteen bacterial pathogens were isolated from sputum samples during 2011-2015, including streptococcus pneumoniae(21.62%), staphylococcus aureus(16.99%), haemophillus influenzae(14.48%), klebsiella pneumoniae(11.97%), escherichia coli(8.11%), moraxelle catarrhalis(3.8%), acinetobacter baumanii(3.86%) and pseudomonas aeruginosa(3.86%). High resistant rates were detected for S. pneumoniae to clindamycin(90.18%), erythromycin(92.86%) and sulfamethoxazole (85.50%), while S. aureus was highly resistant to penicillin G(90.91%) and erythromycin(68.18%). Resistance to vancomycin and linezolid was not detected for gram positive cocci. The resistant rate to ampicillin was 32% for H. influenzae, which was in concordance with the production of β-lactamases. Relatively high resistance was detected for K. pneumoniae and E. coli to cephalosporins and quinolones. A carbapenem-resistant K. pneumoniae isolate was also detected. Conclusion Multiple bacterial species were isolated from lower respiratory tract infections in our hospital, including different species of gram positive cocci and gram negative bacilli, and these isolates exhibited high resistance to antibiotics tested. The clinical use of antibiotics and hospital infection and transmission of these pathogens should be controlled.

Objective To explore the application value of color Doppler ultrasound in patients with azoospermia who underwent testicular needle biopsy. Methods Retrospective analysed the clinical data of 53 cases patients with azoospermia from 2012 November to 2015 February in our department.All patients underwent routine scrotal ultrasonography, to detecte the peak systolic velocity (PSV), end diastolic velocity (EDV) and resistance index (RI) of testicular artery (TA)and intratesticular artery (ITA)with spectral Doppler ultrasound. Color Doppler ultrasound was used to observe the distribution and the number of blood vessels in the testicle, and semi quantitative score. All patients underwent testicular biopsy and Johnsen score. Results 47 patients were diagnosed as obstructive azoospermia(OA), 6 patients were diagnosed as non obstructive azoospermia(NOA). The average volume of testis was (15.3±3.6)mL in 0A group. The average volume of testis was (7.1±2.8) mL in N0A group.There was significant difference (P<0.01). The blood flow parameters(PSV, EDV, RI) results between OA group and NOA group have obvious difference,the difference was statistically significant (P<0.05). The semi quantitative classification of testicular vessels between OA group and NOA group have obvious difference,the difference was statistically significant (P< 0.01). Conclusion Color Doppler ultrasound is a good predictor of testicular spermatogenic function, can be used as the identification index of patients with OA and patients with NOA.

Objective The aim of this study was to explore induction and differentiation of endogenous neural stem cells(ENSCs) in the hippocampus soluble factors(HSF) from the hippocampus of adult Wistar rats by mimicking an intracranial microenvironment. Methods After Wistar rats sacrificed, the hippocampus tissue was obtained in cold DMEM/F12. After centrigued and filtered, the HSF was stored at -20℃. The ENSCs was obtained from the hippocampus tissue of a neonate Wistar rat. Collected the tissue, digested and obtained the ENSCs. After we observed the morphology, the ENSCs were cultured in different concentration (0、50、100、200、400 μl/mL) of HSF for 6 days, and compared the expression of Nestin and CD133 by immunocytochemistry. Meanwhile,we compared the Nestin and CD133 protein by western blot. And then we explored the optimal concentration of HSF by the numbers of all groups on the second and sixth day. Furthermore, we did the differentiated experiment using the same concentration of HSF. Results The number of neurospheres in the 100 μg/mL group was significantly higher than those in the other groups on the 6th day. Immunofluorescence revealed that the neurospheres from ENSCs in the 100 μg/mL group more highly expressed nestin and CD133 than control. This result was confirmed by western blot analysis. The neurospheres can differentiate into glia-like cells in 100 μg/mL HSF and 1% FBS expressing GFAP, S100 and P75 NGFR by immunofluorescence. Conclusion These data indicated that HSF alone, mimicking a destination of ENSCs in vitro, could induce and differentiate neurospheres from ENSCs, as a new method to get NSCs and glia-like cells differentiated from ENCs to repair the diseases of center nervous system.

Objective In an attempt to reduce the risk of intraoperative recurrent laryngeal nerve (RLN) damage, human autopsy was conducted to determine the distribution of RLN and its relationship with surroundings. Methods With the naked eye observation, 20 formalin-fixed adult cadavers were examined. The relationships between RLN and inferior thyroid artery and inferior horn of thyroid cartilage were defined. Both the distance between entering point and inferior horn of thyroid cartilage and the distance between inferior horn of thyroid cartilage and middle point of clavicle bone or upper margin of stern were measured. Results The proportion of cases for recurrent laryngeal nerves intercrossed with inferior thyroid artery and for the crossing above the plane of inferior pole was respectively 88% and 96%. Therecurrent laryngeal never in front and rear of the inferi of thyroid artery and its branches were 22% and 50%,respectivdly.Most cases of RLN were behind Berry s suspensory ligament (95%). The distance between entering point of recurrent laryngeal nerve and inferior horn of thyroid cartilage was 8.2±2.5mm. Conclusion The results suggested that the correlation between RLN and its surrounding tissues is very complicated. The inferior horn of thyroid cartilage may be a useful marker for RLN.
