Objective:In 2003,a survey of the manpower of pediatric dentists was made in China in order to provide basis for database. Methods:Questionnaires were distributed to dentists presenced the 5th conference of pediatric dentistry in China,and 139 available answers were analysis. Results:In those 139 pediatric dentists, with a mean age of 38.2?8.7,females were significantly more than males, and 89.9% dentists had bachelor, master or doctor degree. Significant relations were found between self-estimate ability of dentists and their length of work, degree, character of clinic.Conclusion:To date, the team of pediatric dentists begins to take shape, the structure of age and education are rational, but the number of them is insufficient and it is necessary to improve the basic and continuing education.

Computed tomography(CT) has enabled early recognition and treatment of focal injuries in patients with head trauma. However, CT has been less beneficial in identifying diffuse brain injury(DBI). The authors have analyzed retrospectively, a series of 132 patients with OBI observed for 2 years from Aug. 1986 to Jul. 1988 to evaluate the significance of the factors affecting outcome. Eighty-three patients were selected as being compatible with moderate and severe diffuse axonal injury(DAI) classified by Gennarelli, defined by coma without a CT lesion that is an obvious cause and coma greater than 24 hr with or without decerebration. The results are summarized as follows: 1) The 38(45.7%) out of 83 patients were found below age of 20, but there was no statistical significance between age distribution and outcome. 2) In case of initial Glasgow coma scale(GCS) of 7 or 8, 32(86.5%) out of 37 patients revealed good outcome, but 18(90%) of 20 patients with a score of 3 or 4 revealed poor outcome(p<0.01). 3) With regard to brain swelling in CT, there was significant statistical difference to outcome(p<0.05). 4) Small hemorrhages on corpus callosum, basal ganglia, basal cistern, peritentorial, lateral ventricle that is characteristic CT findings for DAI were showed 58(70%) out of all cases. It might be concluded that initial GCS, brain swelling and small hemorrhages in CT were significant factors affecting outcome in DAI.

TiO2 coated hollow fiber ( HF) was prepared by sol-gel method and characterized by X-ray powder diffraction and scanning electron microscope. The adsorption performances of the self-prepared TiO2 coated HF for interest metal ions were explored. The sample solution was extracted for 30 min at pH 8. 0 under stirring at speed of 700 r/min, then desorpted with 100μL of 1 mol/L HNO3 . On the basis of this, a method combining TiO2 coated HF micro-solid phase extraction with electrothermal vaporization-inductively coupled plasma mass spectrometry ( ICP-MS ) was developed for the determination of trace metal ions in environmental water samples. Under the optimized conditions, the limits of detection obtained by the proposed method were 0. 039, 0 . 021 , 0 . 009 and 0 . 018 ng/mL for CrⅢ, CuⅡ, CdⅡ and PbⅡ with enrichment factors of 12 . 5 , 11 . 7 , 10. 3 and 18. 6, respectively. The preparation reproducibility of self-prepared TiO2 coated HF ranged from 4. 5% to 6. 8% (n=9) in one batch, and from 7. 7% to 9. 6% (n=7) in batch-to-batch. The developed method has been validated by analyzing a certified reference material ( GSBZ50009-88 200925 ) and also applied to the analysis of CrⅢ, CuⅡ, CdⅡ and PbⅡ in East Lake water and snow water successfully. Meanwhile, TiO2 coated HF stir bar was prepared for a comparison and it was demonstrated that TiO2 coated HF displayed higher extraction efficiency and adsorption capacity for target ions.

OBJECTIVE To investigate the accumulated effect and the mechanism of repeated sc administration of acrylamide (AM) on learning and memory after 28 d,and the effect of AM on the amplitude of population spike(PS) potential after a single sc administration of AM. METHODS Female Wistar rats were sc adminstered with AM 10, 20 and 40 mg · kg-1 once a day for 28 d, and weighted every week. The ability of study and memory was evaluated, The morris water maze was used from 22nd to 28th day,followed by step down test on the 29th and 30th day. The escape latent period and the number of errors in those two days were recorded. Rats from normal control group and AM 40 mg·kg-1 group were taken to have their N-methyl-D-aspartate receptor (NR) and calmodulin-dependent protein kinaseⅡ (CaMKⅡ) protein levels detected by Western blotting. Additionally, some other female Wistar rats were sc administered with a single dose of AM 40 mg · kg-1 ,before the changes in PS potential amplitude induced by high frequency stimulation were recorded by long-term potential (LTP). RESULTS Compared with normal control group, the relative body mass gain was significantly decreased in AM exposure groups(P<0.01). Additionally, the escape latency period was significantly increased in AM 20 and 40 mg·kg-1 groups compared with normal control group, while the crossing frequency was not significantly different betmeen these four groups. Compared with the first day of step down test, the number of errors was significantly decreased(P<0.01) and the escape latency period was significantly extended(P<0.01) in normal control group on the 2nd day. However, the number of errors and the escape latency period did not significantly change in the AM groups between the two days. The results of Western blotting showed that the protein expressions and phosphorylation of NR2A and NR2B, as well as the phosphorylation of CaMKⅡ in AM 40 mg · kg-1 group were significantly increased compared with normal control group. LTP result showed that AM 40 mg·kg-1 significantly inhibited the amplitude of PS potential after a single percutaneous administration. CONCLUSION AM can inhibit the PS amplitude by inhibiting the release of glutamate, increasing the expressions and activities of NR,and inhibiting PS potential, thus affecting the hippocampal synaptic plasticity, and the function of learning and memory.

Objective:To systematically evaluate the effectiveness of early enteral nutrition after hepatectomy of hepatic carcinoma in China.Methods:The database such as CNKI,VIP,WANFANG DATA and CBM were searched electronically to collect the randomized controlled trials about enteral nutrition (EN) versus parenteral nutrition (PN) after hepatectomy.Meta-analyses were performed using the RvmanS.3 software.Results:Seven randomized controlled trials involving 460 patients were included.The analysis showed that the EN had significantly higher levels of albumin (WMD =1.17,95％ CI:0.45 ～ 1.89,P =0.001) and lower levels of aminotransferase (WMD =-3.95,95 ％ CI:-7.08 ～-0.81,P =0.O1) than those in the control group.The time of gastrointestinal function recovery in EN group was shorter than that in PN group.There was no significant difference in body weight and adverse reactions of gastrointestinal tract.Conclusion:Early enteral nutrition support for patients after hepatectomy of hepatic carcinoma shows certain advantages,which can improve the nutrition status and be in favor of the recovery of liver and gastrointestinal function.

Objective To explore the application of mini-clinical evaluation exercise (Mini-CEX) in training the diagnostic thinking ability for clinical interns.Methods 83 interns who came to the First People's Hospital of Lianyungang for clinical practice in June 2015 were divided into the experimental group (45 interns) and the control group (38 interns) according to their schools.The two groups received the same clinical teaching according to internship program of five-year clinical medicine,while the experimental group had to take a weekly Mini-CEX training in chnical sections.The diagnostic thinking ability of the two groups was measured by the Diagnostic Thinking Inventory in Chinese version at the beginning and the end of the internship respectively.SPSS 21.0 was applied to processing the data.Measurement data were expressed as mean plus or minus standard deviation,and t test was used in the comparison between groups.Results At the end of the internship,the total score of diagnostic thinking,the score of knowledge structure in memory and the score of flexibility in thinking of the experimental group were higher than scores at the beginning statistically,and the experimental group had a statistically higher score than the control groups in knowledge structure in memory [(69.36 ± 4.28) vs.(66.95 ± 4.78),P=0.018].Conclusion Mini-CEX training can enhance the clinical diagnostic thinking ability of interns by improving their knowledge structure in memory.
