Objective To investigate the effect of fluoride on expression of Runx2 mRNA and protein in bone tissue of rats. Methods Fourteen SD rats were randomly divided into two groups: control group(tap water with fluoride ＜ 0.06 mg/L), and fluorosis group(fluoride 50 mg/L in water). After 4 moths, expressions of both mRNA and protein of Runx2 in rat bone tissue were determined by RT-PCR and Western blotting. Results The results showed that the expression of Runx2 mRNA and protein in fluoride-treated bone tissue were 2.287 ± 0.261 and 0.929 ± 0.229, respectively, both of which were significantly higher than those of control group(0.995 ± 0.123,0.317 ± 0.068, t = 11.85,6.78, P ＜ 0.05). Conclusions Fluoride can increase the expression of Runx2 mRNA and protein in bone tissue of rats, and Runx2 may be involved in the pathogenesis of bone injury caused by fluoride.

The forkhead box O (FoxO) transcription factor family plays an important role in cell functions, including metabo-lism, apoptosis, cellular proliferation, stress reactions, DNA repair, and immune response. As a member of this family, forkhead box O3a (FoxO3a) regulates its target genes by modulating histone modifications, including phosphorylation, acetylation, and methylation. FoxO3a expression is abnormally downregulated in urologic neoplasm. Protein modifications and FoxO3a activity are mainly con-trolled by PI3K/Akt signal pathway and other signaling pathways. FoxO3a is also involved in the initiation, progression, and prognosis of urologic neoplasm. This review focuses on the function of FoxO3a in urologic neoplasm and elucidates the regulatory mechanisms involved. This article will provide novel strategies to clinical diagnosis and drug therapy of urologic neoplasms.

Objective: To evaluate the efficacy of postoperative radiotherapy in the treatment of parotid gland carcinoma. Methods: Eighty-six postoperated patients with parotid gland carcinoma( 7 in stage Ⅰ, 28 in stage Ⅱ, 33 in stage Ⅲ and 18 in stage Ⅳ) were radiated by 60Co ?-ray or linear accelerator X-ray combined with electron beam. All patients were diagnosed by pathology and followed up for more than 5 years. Results: The five year survival rate and the local control rate were 73.3% and 87.2% respectively. Poor prognosis was observed in the cases with the neoplastic classification of undifferentiated carcinoma, sequamous cell carcinoma and malignant pleomorphic adenoma, but the better prognosis was obtained in the cases with acinic cell carcinoma and mucoepidermoid carcinoma. Poor prognosis was observed in the cases with stage Ⅲ and Ⅳ of clinical stage. Radiotherapy undertaken in 2 weeks after surgical operation gave higher 5- year survival ratio( 83.8%). The group given 51～60 Gy radiation showed 82.9% of five- year survival rate. Conclusion: The combination of surgery with radiation is effective in the treatment of parotid gland carcinoma.Radiation of 51～60 Gy 2 weeks after operation may result in better prognosis. Neoplastic type and clinical stage are important factors for prognosis.

OBJECTIVETo observe the effect of natural borneol on the permeability of blood tumor barrier (BTB) model and the expression and activation of mitogen-activated protein kinase (MAPKs) signal transduction pathway related protein kinase in vitro.

METHODSC6 rat glioma cells and human umbilical vein endothelial cells (HUVECs) were co-cultured to establish BTB model. Then 4 groups were set up, the blank control group, low, middle, and high dose borneol groups (25, 50, 100 µg/mL), 3 samples collected at 7 time points (0, 10, 30, 60, 120, 180, 240 min, respectively). Blank culture medium was exchanged in the blank control group while medication. Different doses of natural borneol were administered to the 3 borneol groups. Cells were collected at different time points. BTB permeability was determined using horseradish peroxidase (HRP). Expression levels of extracellular signal regulated protein kinase (ERK), phosphorylation extracellular signal regulated protein kinase (P-ERK), P38MAPK, phosphor-P38MAPK, c-Jun N-terminal kinase (JNK), and phosphorylation c-Jun N-terminal kinase (P-JNK) were detected using Western blot.

RESULTSCompared with the same group at min 0, the permeation rate obviously increased (P < 0.01) in the 3 borneol groups at the rest time points. P-ERK expression was elevated first, reached the peak at 30 min, and gradually recovered to the initial level (P > 0.05). Compared with the blank control group, HRP permeation rate increased from 10 min to 240 min (P < 0.01), and expression of P-ERK protein increased at 30 min and 60 min (P < 0.05) in the low dose borneol group; expression of P-JNK protein decreased in the 3 borneol groups at 180 min and 240 min (P < 0.05). Compared with the low dose borneol group, expression of P-ERK protein increased from 10 min to 180 min (P < 0.05), HRP permeation rate increased from 30 min to 180 min (P < 0.05), expression of P-JNK protein decreased at 180 and 240 min (P < 0.05) in the middle dose borneol group. Compared with the middle dose borneol group, HRP permeation rate increased from 10 min to 180 min (P < 0.05), expression of P-ERK protein increased from 10 min to 180 min (P < 0.05), expression of P-JNK protein increased at 180 min and decreased at 240 min (both P < 0.05) in the high dose borneol group.

CONCLUSIONNatural borneol arrived at the effect of regulating reversible BTB patency possibly through activating phosphorylation of ERK in MAPKs signal transduction pathway, and further reversibly down-regulating expression of associated proteins.

Abstract: Objective　In order to provide reference for emergency treatment of a sudden food poisoning incident, pathogen detection and drug resistance analysis were carried out. Methods　Diarrheal stool and surplus food samples were detected by GB 4789 and the isolates were identified by VITEK2 and matrix assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS), at the same time, the bacterial drug sensitivity test was carried out by using the method of microbroth dilution, and the isolates from different sources were molecularly classified by pulsed field gel electrophoresis (PFGE), and the correlation between the strains was analyzed by BioNumerics software. Results　Totaly 13 leftovers and 3 diarrhea patients were isolated and identified, The total number of colonies and coliforms in 7 leftovers samples all exceeded the standard, and Citrobacter freundii was detected in 5 leftovers and 2 stools. The results of drug sensitivity test showed that seven strains of Citrobacter freundii were sensitive to ciprofloxacin, tetracycline, chloramphenicol, gentamicin, amikacin, cefotaxime and meropenem, but completely resistant to ampicillin, and there was no multiple drug resistance. The results of pulsed field gel electrophoresis (PFGE) showed that 7 strains of Citrobacter freundii had the same PFGE bands and 100% homology, showing the same clone. Conclusions　This food poisoning incident was caused by Citrobacter freundii. The pathogen of food poisoning can be quickly and accurately determined by MALDI-TOF MS, which is beneficial to the early diagnosis and treatment of infectious diseases. It is suggested to strengthen the corresponding management, improve food safety awareness and prevent similar incidents.

AIM:To explore relationship between the normal strehl ratio ( SR ) values of total aberrations/SR values of total higher-order aberrations and modulation transfer function ( MTF ) at total corneal at different pupil diameters in normal population.
METHODS: To exam the SR values of total aberrations and SR values of total higher-order aberrations of total corneals in 200 people ( 400 eyes ) using SIRIUS 3D topography system and analysis the corresponding root-mean-square ( RMS) .
RESULTS: The subjects with different pupil diameters (3. 0, 5. 0, 6. 0, 7. 0mm)'s exam results of total corneal were as following:SR value of total aberrations 100’(0. 45±0. 12), (0. 25±0. 06), (0. 17±0. 05), (0. 13±0. 04); SR value of total higher order ab cerrations 100’(0. 69±0. 14), (0. 34±0. 07), (0. 24±0. 05), (0. 16±0. 04);SR value of total aberrations 200’(0. 45±0. 12), (0. 24±0. 06), (0. 20±0. 04), (0. 16±0. 03); SR value of total higher order aberrations 200’(0.70±0. 13), (0. 35±0. 07), (0. 27±0. 06), (0. 20±0.04 ) . The SR values of each group decreases with the increases of pupil diameters. The SR values of total aberrations and SR values of total higher - order aberrations at total corneals are negatively correlated with corresponding RMS value. When the pupil diameter is small, the SR value of total aberrations is more related to higher frequency region of MTF. When the pupil diameter is big, the SR value of total aberrations is more related to lower frequency region of MTF.
CONCLUSION: The visual performance of normal people can be well reflected by SR values of total aberrations and SR values of total higher - order aberrations at total corneal.
