Objective:To investigate the root and canal morphology of mandibular first permanent molars in adolescents by cone-beam computered tomography (CBCT).Methods:366 mandibular first permanent molars in 1 83 adolescents aged 1 2 -1 6 years were examined by CBCT from July,201 2 to December,201 3.The age,sex,the number of roots and canals and canal morphology were re-corded.The data were statistically analyzed by software SPSS 1 9.0.Results:365 mandibular first permanent molars showed single mesial root except one with C-shaped root;282(77.05%)teeth had one distal root,83(22.68%)had two.356(97.27%)teeth had two mesial canals and 9(2.46%)had one.229(62.57%)teeth had one distal root with one canal,53(1 4.48%)had one distal root with two canals.83(22.68%)had two distal roots with one canal in each root,one (0.27%)had C-shaped root with three canals. There were no significant differences between males and females and between the two sides on the number of roots and number of ca-nals.Conclusion:Majority of mandibular first molars have two roots,the root change occurs in distal root.The prevalence of three-rooted mandibular first molars has no significant difference between genders and 2 sides.

Based on the global burden of disease classification, to explore the scope of chronic diseases. Methods:Searching relevant literature and books to screen and remove the acute non-communicable diseases among the non-communicable diseases which is the second category of global burden of disease ( GBD) classification. Results: Acute non-communicable diseases mainly concentrated on the acute inflammatory diseases, it also existed in other acute diseases which are not caused by infection. Conclusion: To screen and remove the acute non-communicable diseases in the non-communicable diseases could define the scope of non-communicable chronic diseases on certain extent, which has certain significance for the workers who study all chronic diseases.

Objective To observe the changes of nerve function and nerve sorbitol in diabetic rats and to explore the effect of sodium fulvate (SF). Methods Diabetic rats were induced by intraperitoneal injection of streptozotocin. One group of diabetic rats were given SF for six months. Plasma glucose, HbA 1c and nerve sorbitol were measured, and pain threshold was detected by thermalpain apparatus and hotplate test. Results (1)There was no effect of SF on hyperglycemia in diabetic rats. (2)The withdrawal latency was significantly decreased and nerve sorbitol content was significantly increased in untreated diabetic rats. (3)Untreated diabetic rats showed pain reaction at non noxious temperature (40℃) and the times of hind paw withdrawal reflex per minute at 44℃ were increased in hotplate test 〔(3.42?0.59)/min〕 as compared with non diabetic control group 〔(0.88?0.36)/min〕 (P

Objective To investigate the responsiveness of the Burke Lateropulsion Scale (BLS) evaluating Pusher syndrome recovery and the characteristics of BLS. Methods 48 patients diagnosed as Pusher syndrome after stroke were included. All the patients were assessed with BLS to measure the progress at admission, every 2 weeks and at discharge, respectively. The characteristics of BLS score at admission and discharge and the standardized response mean (SRM) were analyzed. Results 56.3% patients were rated as mild and 16.7% were rated as severe at admission; none were classified as severe, 43.8% were not enough to be diagnosed as Pusher syndrome and 47.9% were classified as mild on discharge. SRM was 1.27 during the whole hospitalization, and SRM was 1.41 and 2.18 at 4 and 6 weeks, respectively. Conclusion BLS is an appropriate tool for the evaluation of patients with Pusher syndrome and is responsive to monitor the progress and recovery during rehabilitation.

Objective To investigate the cytokine spectrum of cultured human amniotic-derived mesenchymal stem cells (A-MSC) for understanding its basis of molecular biology in hematopoietic in vitro.Methods Their hematopoietic cytokines expression was analyzed using RT-PCR in the mRNA level. Results It showed that in vitro subcultured human amniotic-derived mesenchymal stem cells were capable to express many important hematopoietic cytokines such as LIF, SCF, M-CSF, G-CSF, GM-CSF, IL-3, IL-6, IL-11 and so on. Conclusion Production of abundant of hematopoietic cytokines by human amniotic-derived mesenchymal stem cells may be effective for hematopoietic support and HSC transplantation.

Objective To investigate the effects of protein active composition of Scorpio on apoptosis of L1210 tumor cells for the purpose of establishing the quality evaluation method of biological effect of Scorpio. Methods L1210 cells were examined by trypan blue exclusion. The proliferation of cells was determined by improved MTT assay. Flow cytometry was performed to analyze cell apoptosis with propidium iodide (PI). Results When the concentration of protein active composition of Scorpio exceeded or equaled 37 mg/ml, the coefficient correlation of the growth inhibiting curve of L1210 cells was 0.9357, and IC50 was 175 mg/ml. The excellence time was 0 to 48 hours. When the concentration of protein active composition of Scorpio exceeded or equaled 9.25 mg/ml, the apoptosis ratio of L1210 cells was raised significantly.Conclusion The protein active composition of Scorpio might promote the apoptosis and restrain the proliferation of L1210 cells. The value of anti-tumor biological effect of the protein active composition of Scorpio was 9.25 ～ 175 mg/ml. This value may be one of the indexes for quality evaluation of biological effect of Scorpio.

Objective To observe the significance of tumor abnormal protein (TAP)in the therapeutic monitoring of non-small cell lung cancer (NSCLC).Methods Peripheral blood from 30 NSCLC patients were collected to make smears at the moment of pre-treatment,half a month,one month,3 months and 6 months after therapy.TAP was detected by coacervation method.The maximum area of condense was applied to estimate the level of TAP.Thirty healthy subj ects were chose as con-trol group.Results The positive rate of TAP in NSCLC patients was 86.67%,and 3.33% of healthy subjects were positive in TAP.The difference was statistically significant (χ2=140.3,P<0.01).The condense area of TAP in patients withⅢ~Ⅳ stage of NSCLC [411(89,562)mm2]was significantly higher than those withⅠ~Ⅱ stage NSCLC [267(31,407)mm2]. The condense areas in both of two groups went down after treatment.A significant difference of condense area appeared inⅠ~Ⅱ stage of NSCLC patients a month after therapy as well as Ⅲ~Ⅳ stage of NSCLC patients half a month after treat-ment.The condense areas went to their lowest level 3 months after therapy.ForⅠ~Ⅱ stage patients,the condense area fell to 21% compared to that before treatment,but for patients withⅢ~Ⅳ stage of NSCLC,37% of pre-treatment condense ar-ea were detected.TheⅠ~Ⅱ stage of NSCLC patients had a greater decrease in condense area of TAP than theⅢ~Ⅳ stage patients by 3 months after treatment (χ2=6.22,P<0.05).Conclusion Detection of TAP in peripheral blood had a high sensitivity for NSCLC,and is able to monitoring the treatment effect.
