BACKGROUND:Hard palate mucosa serves as a main donor material in periodontal plastic surgery and its thickness is crucial for the surgical outcomes. OBJECTIVE: To analyze the thickness of hard palate mucosa in Han population, and analyze the consistency between cone-beam CT image analysis and trans-gingival probing method. METHODS: A total of 30 Han volunteers (300 teeth) were recruited, and the thickness of hard palate mucosa was measured using cone-beam CT image analysis or trans-gingival probing method, to analyze their consistency. RESULTS AND CONCLUSION: The two methods showed a higher consistency in the thickness of hard palate mucosa at the cuspid, first and second premolars as well as first and second molars. The thickness of the hard palate mucosa related to the distance from the gingival margin and tooth position, the thickness from the canine region to the second premolar region thickening gradually, and became the thickest at the second molar, and the thinnest at the cuspid. This study for the first time analyzed the thickness of hard palate mucosa in Chinese Han population, and confirmed there is a high consistency between cone-beam CT image analysis and trans-gingival probing method.

Since the establishment of the People’s Republic of China, the development of China’s official de-velopment assistance for health has been going through three phases. To date, it has developed in many forms, inclu-ding the dispatch of medical team and the construction of health facilities. Since the market reforms, the global con-text together with the domestic socioeconomic foundations have changed; the impact of China’s relatively simple and segmented development assistance for health on the development of health systems in developing countries is limited;the effectiveness of assistance has been watered-down due to segmentation and vague management and accountability systems, as well as the lack of an overarching strategy;China’s health institutions, techniques and products suffer va-rious obstacles in their transfer to other countries where rules are dominated by western countries;compared with the increasing and multiple demands of development assistance for health from developing countries, the capacities of co-operation need to be further developed. As the paper suggests, use the “new major-country” and “new morality-in-terest” and“human oriented” concepts, as well as the ideology of“aid in order to develop, develop in order to coop-erate, so as to develop hand-in-hand” to guide China’s development assistance for health;innovate stereo-aid models to adapt to the changed foreign and domestic socioeconomic context; reform the development assistance for health management system and define rights and obligations appropriately;strengthen coordination and information sharing;link development assistance for health with global health governance to promote a maximized spillover effect;mobilize the civil society with strengthened guidance and supervision.

ObjectiveTo investigate and compare the efficacy, safety, and cost effectiveness in the treatment of painful osteoporotic vertebral compression fractures ( OVCFs ) with percutaneous vertebroplasty (PVP) and kyphoplasty(PKP). MethodsSeventy-two patients (96 vertebrae) with painful OVCFs were treated by PVP (n =34) or PKP (n =38) under radiological monitoring. After bone biopsy needle into the compressed vertebra, bone cement (polymethylmethacrylate) was injected in PVP group, and that was inserted followed by the inflation of vertebra to create cavities in PKP group. The fluoroscopy time, total amount of bone cement injected, and cost were recollected respectively. The score of visual analogue scale point( VAS, 10-point scale)was determined at before the procedures, and 24 hours, one week, and one month after the procedures.Pain relief and complications were observed.The Cobb angle and vertebral heights of the anterior, middle, and posterior border were measured pre-and post-operative. ResultsThe two procedures were technically successful in all patients. The follow-up ranged from 1. 0 to 34. 0 months [mean time, (8. 9 ±3.2) months]. The Mean fluoroscopy time of treating per vertebra in PVP group was ( 11. 1 ± 10. 6 ) min, which was significant shorter than that ( 23.5 ± 13. 0) min in PKP group( P <0. 05 ).The mean total cost per patient was (5127. 2 ± 502.3 ) yuan in PVP group, which were strikingly lower than that(32 301.4 ±3204. 6) yuan in PKP group (P <0. 05).(3)There was no significant difference( P >0. 05 ) in average cement volumes in PVP group [ (4. 9 ± 1.1 ) ml]and PKP group [ (5.4 ± 1.7 ) ml]. Pain relief of was observed in 94. 1% (32/34) of PVP group and in 92. 1% (35/38) of PKP group. The score of VAS at pre-operation was (8. 3 ±0. 4 vs 7.9 ±0. 8) ,and at post-operative 24 h (2. 9 ±0. 9 vs 2. 8 ± 1. 2),1 week (2.6 ± 0. 9 vs 2.6 ± 1. 1 ), and 1 month (2.6 ± 0. 9 vs 2. 5 ± 1.3 ) were no difference at PKP and PVP group(P <0.05). There was significant difference between pre- and post-operative time point in each group. The Cobb angle, anterior and middle height of vertebra was corrected in both PVP and PKP group. In PVP group, the preoperative Cobb angle, anterior and middle height of vertebra was (24. 2 ± 3.8 )°,( 19. 1 ± 1.4) mm, (25. 2 ± 1.0) mm, which was significant different ( P < 0. 05 ) from that of ( 19.4 ±3.9)°, (21.0 ± 1.5) mm, (27.0 ± 1.2) mm at pre-operation.In PKP group,there was significant difference (P < 0. 05 ) in the preoperative Cobb angle, anterior and middle height of vertebra [(25. 1 ±5.0)°vs(10.7 ±2.8)°, (19.5 ± 1.5) mm vs (24.3 ± 1.9) mm, (25.4 ± 1.1) mm vs (29.7 ±1.3) mm, respectively]. As to the above index, the overall correcting effect in PKP was much better than that in PVP( P <0. 05 ). Cement leakage occurred in 9 cases in PVP group and 3 cases in PKP group ( P <0. 05 ) but no symptoms. There were no major complications during operation in the two groups. Conclusion PVP and PKP are effective and safe in the treatment of painful OVCFs but PVP is more cost effective than PKP.
