Objective To investigate the distribution and drug resistance of major pathogens for urinary tract infections in the First Affiliated Hospital of Nanjing Medical University.Methods Strains from midstream urine culture of patients with urinary tract infections were collected during January 1 and December 31,2011.All strains were identified by API system,and disk diffusion method was used for drug sensitivity test.Results Totally 1129 strains were isolated,in which 667 (59.1％ ) were Gram-negative strains,266 (23.5％) were Gram-positive strains,and 196 (17.4) were Candida.Among Gram-negative strains,Escherichia coli,Klebsiella pneumoniae and Proteus mirabilis were highly sensitive to carbapenem antibiotics; while Acinetobacter baumannii and Pseudomonas aeruginosa were highly resistant to most antibiotics including cephalosporins and penicillinase inhibitor,and the resistance rates were over 50％.Among Gram-positive strains,the major strains Enterococcus avium and Enterococcusfaecalis were completely sensitive to vancomycin and teicoplanin,and highly sensitive to linezolid (resistance rate below 10％ ).Candida albicans and Candida glabrata were highly resistant to voriconazole and fluconazole (with the resistance rates of 47.2％ - 60.0％ ), but were completely sensitive to amphotericin and nystatin.Conclusion Gram-negative strains account for most urinary tract infections in the First Affiliated Hospital of Nanjing Medical University with high drug resistance rates.

BACKGROUND:Morphological characteristics of the rabbit lumbar vertebrae are of great significance for animal experiments about lumbar spine, but there is a lack of study on the lumbar morphology in rabbits. OBJECTIVE:To establish a three-dimensional model of rabbit lumbar vertebrae, and to observe its morphological characteristics, thereby providing anatomical basis for the animal experiments about lumbar spine.METHODS:Twenty New Zealand rabbits were subjected to 64-row multi-detector CT (Siemens) scan, and the three-dimensional models were constructed based on the CT data from 140 lumbar vertebrae. The morphological parameters of L1-7 were measured, and the internal and external structures of lumbar vertebrae and changes of different segments were observed. RESULTS AND CONCLUSION:(1) Changes of the morphological parameters of each lumbar vertebra:the L1-7 height first increased and then decreased, and the shortest height was in the L7, which was (1.12±0.18) cm. L1 vertebral body exhibited the shortest transverse diameter, (1.03±0.15) cm, and the longitudinal diameter did not differ significantly among vertebrae. The transverse and longitudinal diameters of L1-6 spinal canals were on a rise, but decreased abruptly at L7. The pedicle width of L1-7 increased gradually;the pedicle height of L1-5 increased gradually, and then began to decrease markedly, and the shortest at L7, (0.58±0.11) cm. The width and length of L1-6 spinous process increased steadily, but decreased at L7. The length of L1-3 transverse process increased gradually, tended to be steady at L3-6, and increased notably at L6-7;there were significant differences in the transverse process angle at L1-6, but the angle increased markedly to (58±2)° at L7, (2) These results indicate that the internal and external structures of lumbar vertebrae and changes of different segments are obtained through morphological measurement of lumbar vertebrae in New Zealand white rabbit, which provides a detailed anatomical data for relative animal experiments.

Objective To evaluate the clinical significance of fetal nasal bone absence and thickened nuchal translucency ( NT) at 11-13 +6 weeks ultrasound screening .Methods A total of 4200 pregnant women with single fetus registered at Mother and Children ’ s Health Care Center in our hospital were examined at 11-13 +6 gestational weeks .Both fetal nasal bone and NT ultrasound evaluation were offered to assess whether nasal bone is absent and NT is thickened (>3.0 mm) in these cases.Particular attention was paid to the relationship between abnormal findings ,karyotype and pregnancy outcome .Results In all, 3492/4200 cases were included in the study with both NT measurement and nasal bone evaluation .Seven hundred and night cases were excluded because of unavailable clinical outcome .Among 3492 fetuses:(1) There were 3 cases absent of nasal bone .Among the 3 cases without nasal bone , 2 cases ( 1 case combined with thickened NT ) were trisomy 21(66.7%,2/3).(2) There were 351 cases with NT>3.0 mm (10.1%,351/3492).Among the 351 cases with thickened NT,there were 4 with trisomy 21 syndromes (1.14%,4/351,1 case combined with nasal bone absence ),1 with trisomy 18 syndrome,1 with Turner syndrome,6 with structural anomalies but normal karyotype (1.71%,6/351).(3)Among the 3139 cases with normal nasal bone and NT ,there were 8 cases with chromosomal or structural anomalies .Conclusions Absent nasal bone and thickened NT are important markers of trisomy 21 in the first trimester ultrasound screening .Thickened NT has significant correlation with other fetal chromosomal and structural anomalies .

OBJECTIVE: Using the method of lactate dehydrogenase (LDH) assay, to observe the activities of rat cerebral microvascular endothelial cells (CMECs) intervened by Tongluo Jiunao Injection (TLJNI), a traditional Chinese compound drug removing toxin to dredge brain collaterals, and then further study the effects of different kinds of conditioned mediums (CMECs-CM) of cerebral microvascular endothelial cells on ischemia and ischemia/reperfusion cerebral cortex cells, and to probe into the drug pharmacological mechanisms of CMECs in modulating the neurons. METHODS: Three kinds of CMECs (normal, ischemic and ischemic/reperfusional) were all treated by TLJNI previously, and then the three pairs of CMECs-CM without serum were collected respectively for LDH assay. Rat cerebral cortex neurons were also primarily cultured and then divided into similar three groups (normal, ischemic and ischemic/reperfusional). The neuron responses caused by CMECs-CM at different concentrations were observed by using LDH transudation rate assay. RESULTS: The LDH release values of ischemic and ischemic/reperfusional CMECs with TLJNI treatment were obviously reduced (P<0.01) compared with the same kinds of CMECs untreated. For ischemic neurons, both conditioned medium of ischemic CMECs (Is-CM) and conditioned medium of ischemic CMECs with drug treatment (IsT-CM) in high concentration of 100% increased the LDH transudation rate (P<0.01), while in low concentration of 10%, IsT-CM reduced the transudation rate (P<0.05). For ischemia/reperfusion neurons, all kinds of CMECs-CM reduced the transudation rate respectively (P<0.05 or P<0.01). As far as each group concentration was concerned, 10% or 50% showed relatively stronger effects, and both conditioned medium of normal CMECs (N-CM) group and conditioned medium of ischemic/reperfusional CMECs (Rp-CM) group had statistical significance (P<0.05 or P<0.01). For normal neurons, all kinds of CMECs-CM increased the transudation rate respectively (P<0.05 or P<0.01). As far as each group concentration was concerned, only conditioned medium of normal CMECs (N-CM) had statistical significance (P<0.05 or P<0.01). CONCLUSION: The study shows that TLJNI is capable of preventing the damage of CMECs from both ischemia and ischemia/reperfusion states. Chinese drug can restrain the brain ischemia and ischemia/reperfusion damage by the media that CMECs modulate the neurons, demonstrating the pharmacological mechanisms of TLJNI. This work also indicates that there exist some active substances against ischemia/reperfusion injury secreted from CMECs-CM with TLJNI treatment.

Hippo signaling pathway plays an important role in the regulation of organ growth,tissue regeneration,tumor occurrence and development.Transcriptional co-activator with PDZ-binding motif (TAZ)is the downstream transcription factor of Hippo signaling,participates in the regulation of the entire signaling path-way.In recent years,many studies have found that over-expression of TAZ has a close relationship with the oc-currence,development and prognosis of breast cancer.Discussing the relationship of Hippo-TAZ with breast cancer and breast cancer stem cells may provide a new way for breast cancer diagnosis and treatment.

Objective To investigate the effect of sleep position guidance on deformational plagiocephaly and/or brachycephaly (DPB) in the prematures. Methods 321 preterm infants in neonatal intensive care unit from October, 2012 to September, 2015 were divided into sleep positions guidance group (n=159) and control group (n=162). The sleep positions guidance group accepted sleeping positions guidance when they were in neonatal intensive care unit and followed up in child care clinic, and the control group accepted routine treatment and nursing. The incidences of DPB were compared. Results The incidences of mild (χ2=6.591, P=0.010), moderate (χ2=4.862, P=0.027) and se-vere (χ2=11.261, P=0.001) DPB were less in the sleep positions guidance group than in the control group. Conclusion Sleeping positions guidance may reduce the incidence of DPB in prematures.

Objective To investigate the effect of propofol on nNOS expression after focal cerebral ischemia-reperfusion in rats and the possible mechanism of protective effect of propofol on brain. Method Seventy-eight male Wistar rats, weighting 250 ~ 300 g, were randomly divided into 3 groups:(1)Sham operation group (S group, n=6) was performed with scham operation; (2) Ischemia-reperfusion group (group I-R, n=36) was subjected to 2-hour right middle cerebral artery occlusion and then reperfusion was followed, saline (1 mg/kg) was injected into the right lateral cerebral ventricle using microsyringe before reperfusion;(3) Propefol group (group P, n=36) was injected with propofol (1mg/kg) into the right lateral cerebral ventricle using microsyringe right after ischemia. Group I-R and group P were divided into 3 subgroups according to the reperfusion time: 1 h, 3 h and 6 h. The neurological function of all rats were tested before reperfusion. The cerebral infarction area of the whole brain was calculated with TIC staining (n=6). The pathological change of brain was observed from HE staining (n=6) and the nNOS protein expression was obtained by immuno- histochemical method (n=6). Results Compared with I-R group, the neurological function was better in group P(P

Objective To observe the different effects of iodine excess on inducing two strain mice thyroiditis. Methods NOD and Balb/c mice, each having 14 mice, were divided into NaI and control group. The mice were given 0.05% NaI water for 8 weeks in NaI group. RIA and ELISA were used respectively to detect TT4, TgAb, TPOAb and TSH level in serum. Morphology changes of thyroid and apoptosis of thyrocytes stained by immunohistochemistry were observed under light microscope. Lymphocytic proliferation of cervical lymph node and spleen to responding to Tg were detected by MTr method. Results After intake of iodine water for 8 weeks, NOD and Balb/c mice showed relative quality of thyroid in Nal group[(104.83±14.52), (155.79±20.77)mg/kg]obviously increased compared with control group[(71.80±20.42), (105.15±21.98)mg/kg, t values:-3.293,-4.429, all P< 0.01)], enlarged follicular lumen with colloid accumulation were observed in thyroid. Serum level of TT4 in Nal group [(29.52±4.42), (19.53± 2.35)nmol/L]to control group[33.40±5.38), (23.47±6.22)nmol/L]of NOD and Balb/c mice showed a decreasing tendency(t values: 1.374,1.567, all P > 0.05). TSH of Nal group showed an increasing tendency in Balb/c mice[(4.14±1.71)μg/L, compared with control [(3.55±1.41)μg/L, t values:-0.705, P > 0.05]and obviously increased in NOD mice [(6.98±0.66)μg/L, compared with control[(555±056)μg/L, t values:-3.562, P< 0.01], but no change of TgAb and TPOAb level in Nal group(1281,1364 cpm, 2.50×103, 0.14×103U/L were observed, compared with control(1297,1220 cpm, 3.17×103,0.03×103 U/L; Zvalues:-0.081,-0.703, -0.244,-1.293, all P > 0.05). In NOD mice NaI group, apoptosis of thyrocytes was more intense than Balb/c mice, obvious infiltration of lymphoeytes, disorganization and focus fibrosis was seen in thyroid. The cell amount of NaI group increased in NOD mice lymph node and spleen cells[(1.100±0.014), (1.076±0.033)]were more than that in the control group [(0.993±0.011), (1.005±0.003), t value:-11.672,-4.314, P < 0.01). Conclusions Iodine leads to enlargement of thyroid and malfunction of thyroid in Balb/c mice. Besides, NOD mice have generate inflammatory reaction in thyroid and produced sensitized lymphocytes to Tg. Iodine excess can induce NOD mice to occur autoimmune thyroiditis.
