Dental pulp repair with dental pulp stem cells by construction of tissue-engineered dentin-pulp complex / 中国组织工程研究

BACKGROUND: Studies have shown that dental pulp stem cells have high proliferation and multi-directional differentiation abilities and can differentiate into a variety of cells under certain conditions. At present, the use of dental pulp stem cells to construct tissue-engineered dentin-pulp complex is expected to become a new strategy for human dental defect repair . OBJECTIVE: To observe the effect of dental pulp stem cells on the repair of rat tooth defects by construction of tissue-engineered dentin-pulp complex. METHODS: Twenty-four Sprague-Dawley rats were used to make animal models with dental pulp removal, and then model rats were randomly divided into model group and transplantation group. Rats in the transplantation group were subjected to tissue-engineered dentin-pulp complex transplantation, and those in the model group given no treatment. Tooth samples were collected at 3, 5, 7 weeks post transplantation and observed using hematoxylin-eosin staining and immunofluorescence staining. The dentin thickness of rats was measured by Image Pro Plus 6.0 image software system. RESULTS AND CONCLUSION: (1) Dental pulp cells was mostly spindle/oval-shaped and partially polygonal. The third generation of cells with long spindle shape showed fibrous growth and uniform morphology. Findings from immunohistochemical staining showed spindle-shaped deep-colored cells with oval nuclei stained as dark blue were identified as fibroblast-like cells, and were positire for vimtin. (2) Findings from hematoxylin-eosin staining showed vacuolar degeneration of the cells, and hbdestroyed pulp tissue and debris, irregular cord-like tissue, and a large amount of red blood cells and inflammatory cells in the pulp cavity, accompanied by clearly visible vascular dilation. Seven weeks after transplantation, a bundle of odontoblasts were visible in the matrix-like tissues of the dentin, and there was a distinct boundary between the original dentin and regenerated dentin. (3) Findings from immunofluorescent staining showed that after dentin-pulp complex transplantation, the number of cells in the pulp cavity increased significantly at 3 weeks, and there was also a substantial increase in dental pulp cells at 5 weeks that were distributed on the wall of the pulp cavity. Compared with the model group, the dentin thickness in the transplantation group was significantly higher at each time after transplantation (P < 0.05), and in the transplantation group, there was also a significant difference in the dentin thickness at different time points (P < 0.05). To conclude, the tissue-engineered dentin-pulp complex can promote dentin regeneration and repair.

Study on method for formulating clinical practice guidelines of common Chinese patent medicines based on clinical practices / 中国中药杂志

The clinical application of Chinese patent medicines has suffered sever problems and required guidelines for clinical practices. Currently, the expert consensus method is more suitable for formulating clinical practice guidelines of Chinese patent medicines than the evidence-based method. However, there remain problems in the application of the expert consensus method. This study proposed a derivative expert consensus method--a method for formulating clinical practice guidelines of common Chinese patent medicines based on clinical practices, and introduced the method in terms of research thought, methodology and implementation procedure.

A prospective study on the association between dynamic change of waist circumference and incident hypertension / 中华流行病学杂志

Objective To study the impact on dynamic change of waist circumference(WC) through follow-up data on the incidence of hypertension in several cohort groups.Methods In this prospective study,2778 free-hypertension subjects were recruited from a program “Prevention of Multiple Metabolic disorders and metabolic syndrome (MS) in Jiangsu province” (PMMJS) to evaluate the risk of hypertension in relation to WC dynamic change on normal WC or abnorminal obesity group.Dynamic change of WC was measured by WC D-value,which was expressed by data on the difference of WC between baseline and the first follow up.Study outcome was defined as incident hypertension during the first to the second follow up period in this study.The association between dynamic change of WC and incident hypertension was analyzed by using Cox proportional hazards regression model.Results There were 2778 participants,660 subjects developed hypertension during the follow-up,regardless of the normality of the baseline WC,the risk of hypertension increased across the tertiles of WC,while the incidence of hypertension was higher in non-control group than that in control group.In populations with abdominal obesity and normal WC at baseline,RRs (95％CI) of hypertension were 1.95 (1.19-3.19) and 2.38 (1.89-2.99) in subjects with abdominal obesity seen at the first follow up period,compared to subjects with normal WC in the same period.After adjustment for gender,age and other hypertension related risk factors,in populations with abdominal obesity and normal WC at baseline survey,RRs (95％ CI) of hypertension were 4.36 (1.69-9.74) and 1.44( 1.03-2.35 ) respectively,for the non-control group.Conclusion WC dynamic change was associated with hypertension,WC control while WC reduction was important for early prevention on hypertension.

Impact of dynamic change of waist circumference or body mass index in hypertension incidence / 中华预防医学杂志

<p><b>OBJECTIVE</b>To study the impact of dynamic change of waist circumference (WC) and body mass index(BMI) in two years on hypertension incidence in cohort populations.</p><p><b>METHODS</b>A perspective cohort study was conducted. The participants (5888 subjects) whose follow-time were 2 years or longer from the program Prevention of multiple metabolic disorders and metabolic syndrome (MS) in Jiangsu province were investigated. Amongst 5888 subjects, 4582 participants received the first follow-up investigation in January 2002. Among 4582 subjects who received first follow-up investigation and whose follow-time met 5 years, total 3847 participants received the second follow-up investigation in March 2006. Total 2778 free hypertension subjects were included in this analysis. Subjects with normal WC or BMI at baseline but abnormal WC or BMI at the first follow-up or subjects with abnormal WC or BMI both at baseline and the first follow-up were defined as non-control group. Subjects with abnormal WC or BMI at baseline but normal WC or BMI at the first follow-up or subjects with normal WC or BMI both at baseline and the first follow-up were defined as control group. The incidence of hypertension at second follow-up investigation was defined as the final variable(hypertension = 1, non-hypertension = 0). The association between dynamic change of WC or BMI and incident hypertension was analyzed by using Cox proportional hazards regression model. The OR, RR value and 95%CI were calculated through WC and BMI risk stratification.</p><p><b>RESULTS</b>Among 2778 participants without hypertension at baseline, 660 subjects developed hypertension. When both BMI difference value (D-value) and WC D-value were included in the regression model, WC D-value was associated with hypertension in both genders (males: OR = 1.04, 95%CI: 1.01 - 1.05; females: OR = 1.04, 95%CI: 1.02 - 1.06), but BMI D-value was not associated with hypertension in both men and women (males: OR = 1.04, 95%CI: 0.97 - 1.11; females: OR = 0.98, 95%CI: 0.93 - 1.03). Hypertension risk of WC non-control group was higher than that in WC control group in baseline normal and abnormal WC groups (normal baseline WC group: RR = 1.41, 95%CI: 1.01 - 2.39, abnormal baseline WC group: RR = 4.41, 95%CI: 1.66 - 9.80). But in baseline abnormal BMI group, there was no significant difference between BMI control and non-control group (RR = 1.33, 95%CI: 0.88 - 2.02). Whether BMI was controlled can not influence hypertension risk if WC was controlled (males: RR = 1.03, 95%CI: 0.36 - 2.96; females: RR = 1.02, 95%CI: 0.70 - 5.85), however, control WC could reduce hypertension risk obviously even though BMI was not controlled (males: RR = 4.03, 95%CI: 1.61 - 10.09; females: RR = 1.55, 95%CI: 1.13 - 3.60).</p><p><b>CONCLUSION</b>Both WC and BMI dynamic change were associated with change of hypertension.
