Objective:To compare clinical and radiographic success rates of a modified primary root ca-nal filling ( ingredients:zinc oxide-eugenol, iodoform and calcium hydroxide, MPRCF) vs. zinc oxide-eugenol cement ( ZOE) and calcium hydroxide/iodoform paste ( Vitapex) in pulpectomized primary mo-lars at the end of 6 and 12 months, and to evaluate the degradation of materials in the root canals and in apical area. Methods:In the study, 160 primary molars from 155 children ( the average age:5. 88 ± 1. 27 years) that met the inclusion criteria were allocated to one of the three materials via block randomi-zation. A two-visit pulpectomy was performed by an investigator. The clinical and radiographic diagnoses were blindly assessed by other two investigators. Results:At the end of 6 and 12 months, the ZOE and MPRCF success rates were 100% both in clinical and radiographic evaluation. The Vitapex group showed the clinical success of 100% at the end of 6 months and 94. 5% at the end of 12 months. Radiographic evaluation for the Vitapex group showed 80 . 4% success at the end of 6 months and 60 . 7% at the end of 12 months. No statistically significant differences were noted at the end of 6 months in the three groups both in clinical and radiographic evaluation. The success rates in clinical and radiographic evaluation at the end of 12 months for ZOE and MPRCF groups were not significantly different, and better than those for Vitapex group with statistically significant difference. The completely resorb rate of excess extruded extraradicularly were 14. 3%, 100% and 71. 4% for ZOE, Vitapex and MPRCF at the end of 12 months. The rates of resorption of material at the same rate of the root were 5. 8%, 7. 2% and 40. 9% for ZOE, Vi-tapex and MPRCF at the end of 12 months. Conclusion:MPRCF, a mixture of zinc oxide eugenol and io-doform with calcium hydroxide can be used as a root canal filling material in primary teeth, taking account of the success rate and resorbing at a similar rate with the roots of the primary teeth.

This study was aimed to observe the protective effect of astragalus on bones of vitamin D deficiency rat model. A total of 30 male SD rats were randomly divided into 3 groups, which were the control group, model group, and the astragalus group. The experimental period was 8 weeks. After the experiment, enzyme immunoassay was used for the detection of serum 25 hydroxy vitamin D3 [25 (OH)VD3], fibroblast growth factor-23 [FGF-23], Klotho, and HE staining of femur. The results showed that compared with the normal control group, the vitamin D deficiency rat model group had a decrease in both serum 25 (OH)VD3 and Klotho, and a increase in FGF-23, which meant the ex-istence of osteoporosis. Compared with the model group, the astragalus group had a decrease in both the serum 25 (OH)VD3 and FGF-23, and a increase in Klotho, which meant the osteoporosis of the astragalus group had been im-proved significantly. It was concluded that astragalus can regulate FGF-23 and Klotho in vitamin D deficiency rats in order to have a protective effect for bones.

72 cases of treatments on insomnia were recorded in the medical books of Ming and Qing dynasties(A.D.1368～1911 years).The compatibility regularity of treating insomnia in these 72 cases were statistically analyzed with frequency and the R type cluster analysis methods. Combining the data and modern recognition, compatibility and medication regularity of treating insomnia was further analyzed.

Objective To explore the psychological status of patients after hand tenolysis and the pertinent nursing countermeasures. Methods 47 patients after hand tenolyais were selected and investigated their psychological status and relevant influencing factors with serf-designed questionnaire and symptom checklist-90(SCL-90). Besides, corresponding psychological nursing were applied. The SCL-90 results of Chinese Norm were adopted to undergo comparison with them and t test was chosen. Results On the first day after operation, the score of the investigation objectives was significantly different compared with that of the Chinese norm. After pertinent mental nursing, their symptoms alleviated, and no significant difference was seen between them. Conclusions There are obvious psychological obstacles in patients after hand tenolysis. The pertinent mental nursing has important effect on rehabilitation training and functional rehabilitation after hand tenolysis.

0.05).There was a positive correlation between the tempo of the engraftment and the progressive increase of the doses of MNC in the range of (3～5.99)?108/kg,but which was not found in the range of 6?108/kg.Conclusion These results indicate that MNC taken as an index for the measurement of the hematopoietic stem cell/progenitor content can reliably predict hematopoietic reconstitution after both HLA-matched and-mismatched sibling donor peripheral blood stem cell transplantation,with the rate and tempo of engraftment comparable with that in CD34+ cell group,and however,the target dose was reached with one apheresis in all 83 donors in MNC group(100%),as compared with 14 donors in CD34+ cell group(37.84%),suggesting that MNC may replace CD34+ cell as an independent index for the assessment of the stem cell/progenitor content in clinical practice.

Objective To reconstruct sparse views CT image based on defective projection data.Methods The position of bad bins in detector determined whether the linear interpolation was applied to the defective projection data.Moreover,reconstruction of air pixels in CT image was achieved rapidly and accurately.Results he experimental results showed that the proposed method could solve the problem from classical ART-TV method that the robustness was unstable due to the different positions of bad bin in CT detector.Conclusion Compared to analytical reconstruction methods,iterative methods can solve the reconstruction problems in this modality so that the radiologist is facilitated to perform image processing and quantitative analysis.

Objective:To investigate the clinical characteristics and risk factors of alcoholic liver disease (ALD) combined with type 2 diabetes mellitus (T2DM).Methods:The clinical data of 70 patients with ALD combined with T2DM (ALD + T2DM group) who received treatment from March 2015 to March 2020 in the First Affiliated Hospital of Guangxi Medical University were retrospectively analyzed. The clinical data of 69 patients with ALD (ALD group) and 69 patients with T2DM (T2DM group) who concurrently received treatment were also analyzed. Sex, age, body mass index, drinking habits and other basic information in the three groups were collected. The risk factors of ALD combined with T2DM were evaluated by logistic regression analysis.Results:The daily alcohol intake and years of drinking in the ALD + T2DM group were (110.97 ± 79.78) g/d and (25.17 ± 10.05) years, respectively, which were significantly higher than (91.48 ± 64.26) g/d and (21.78 ± 8.91) years respectively in the ALD group ( t = 1.699, 2.102, both P < 0.05). The incidence of metabolic syndrome in the ALD + T2DM group was 34.3% (24/70), which was significantly higher than 15.9% (11/69) in the ALD group ( χ2 = 6.210, P < 0.05). The activity ratio of aspartate aminotransferase/alanine aminotransferase, total bilirubin level, gamma glutamyl transpeptidase activity in the ALD + T2DM group were 1.59 ± 0.93, (64.73 ± 39.90) μmol/L, (522.93 ± 353.66) U/L, respectively, which were significantly higher than (1.04 ± 0.53), (10.37 ± 4.51) μmol/L, (35.73 ± 23.99) U/L, respectively in the T2DM group ( t = 4.280, 3.780, 5.045, all P < 0.05). Triacylglycerol level in the ALD + T2DM group was significantly higher than that in the ALD group [(1.69 ± 1.04) mmol/L vs. (1.28 ± 0.87) mmol/L, t = 2.523, P < 0.05). Prothrombin time and lactate dehydrogenase activity in the ALD + T2DM group were (13.13 ± 2.79) s and (226.17 ± 79.93) U/L, respectively, which were significantly higher than (10.41 ± 0.84) s, (172.63 ± 39.34) U/L, respectively in the T2DM group ( t = 7.715, 4.969, both P < 0.05). Multivariate Logistic regression analysis showed that prothrombin time, triacylglycerol level, years of drinking, gamma glutamyl transpeptidase activity, and amount of drinking were the main risk factors for ALD combined with T2DM ( OR = 2.010, 3.270, 1.230, 1.060, 1.006, all P < 0.05). Conclusion:Patients with ALD combined with T2DM are prone to metabolic syndrome and lipid disorders, which may aggravate the disease. Prothrombin time, triacylglycerol level, years of drinking play an important role in the development of ALD combined with T2DM.
