小切口胆囊切除术中胆道损伤的预防

目的探讨预防小切口胆囊切除术（MC）中胆道损伤的方法。方法对本组15131例MC中发生的18例胆道损伤进行回顾分析。结果1994年12月前施行MC2321例，发生胆道损伤9例（0．39％），1995年以来实施MC12810例，发生胆道损伤9例（0．07％）。结论思想上高度重视、规范手术适应证、规范手术操作是预防MC中胆道损伤的关键。     

巴马小型猪脑死亡状态下血清炎症介质的改变及在肝脏损伤中的作用

目的：探讨巴马小型猪在脑死亡状态下血清炎症介质的变化及对肝脏损伤的作用。方法:巴马小型猪10只，随机分脑死亡组与对照组，每组5只。用颅内加压法建立脑死亡模型，对照组仅开颅麻醉维持，分别于3、6、12、18和24h取血清测丙氨酸氨基转移酶（ALT）、天门冬氨酸氨基转移酶（AST）及IL-1β、IL-6和TNF-α水平。结果:（1）炎症介质变化：脑死亡组动物血清IL-1β、IL-6和TNF-α水平均自脑死亡后3h开始升高，并随时间的延长而继续升高；脑死亡后3、6、12、18和24 h脑死亡组明显高于对照组（P<0.05）。（2）肝脏酶学变化：血清ALT、AST水平自脑死亡后12 h开始升高，并随时间的延长而继续升高；脑死亡后12、18和24 h脑死亡组明显高于对照组（P<0.05）。结论：巴马小型猪脑死亡状态下血清炎症介质升高，并随时间的延长而继续升高。脑死亡状态下肝脏功能的损伤可能与这些炎症介质的水平升高有关。

输血传播病毒样微小病毒基因检测

目的：测定慢性肝炎患者体内输血传播病毒(TTV)样微小病毒（TLMV）的全基因序列，并研究人群中TLMV感染状况。方法：采用日本学者Shunji Mishiro提供的序列选择TLMV-CBD279和CBD-231最保守区设计引物，用慢性乙型肝炎且TTV阳性患者血清制备DNA模板，进行PCR扩增；将阳性PCR产物连接至pGEMR-T质粒，碱裂解法提取质粒DNA并纯化。以T7 引物为起 始全自动荧光测序仪测序。结果：获得162bp基因序列，该序列与日本株CBD231、CBD279同源性为72%，丙型肝炎患者及健康献血员感染率最高。结论：在＊慢性乙型肝炎患者体内存在TLMV感染。     

Patient satisfaction with mini‐implant stabilised full dentures. A 1‐year prospective study

The purpose of this study was to evaluate patient‐centred outcomes with regard to function and comfort after placement of mini‐implants for stabilisation of complete dentures. The trial was designed as a prospective cohort of 12‐months duration and involved 21 subjects in the age of 50–90 years having a full denture in the maxilla or the mandible with poor stability during function. Flapless installation of 2–4 narrow‐body Dentatus Atlas^® implants was performed and retention for the existing denture was obtained by the use of a silicone‐based soft lining material (Tuf‐Link^®). Patients' judgement of perceived satisfaction with function and comfort of the dentures was recorded at baseline, 1‐ and 12‐months post‐treatment using 10‐centimetre visual analogue scales (VAS) and a questionnaire. Clinical examination of the conditions of the peri‐implant soft tissues was performed at 12 months. Nineteen of the 21 patients were available for the 12‐month follow‐up examination. The two drop‐out subjects lost all implants within 1 month and rejected retreatment. Further six subjects lost 1–2 implants, but were sucessfully retreated by insertion of new implants. Overall satisfaction, chewing and speaking comfort were all markedly improved from pre‐treatment median VAS scores of around 4–5 to median scores of 9·0–10 (10 = optimal) at the final examination. The prevalence of positive answers to questions regarding stability/function of the denture increased significantly to almost 100% for all questions. Treatment involving maxillary dentures and the use of short implants (7–10 mm) was associated with an increased risk of implant failure. The results indicate that placement of mini‐implants as retentive elements for full dentures with poor functional stability has a marked positive impact on the patients' perception of oral function and comfort as well as security in social life.     

金天格胶囊用于手部骨折术后辅助治疗临床评价

目的探讨金天格胶囊用于手部骨折术后辅助治疗的效果及对患者生活质量的影响。方法选取医院2016年1月至2019年1月收治的手部骨折患者92例,按随机数字表法分为观察组和对照组,各46例。两组患者均进行有限内固定结合微型外固定架手术,术后均予抗菌及镇痛常规治疗;观察组患者术后加服金天格胶囊。结果观察组患者愈合时间明显短于对照组,Gartland Werley腕关节功能评分明显低于对照组(P<0.05);治疗后,观察组患者的骨代谢指标包括血清骨钙素(BGP)、血清碱性磷酸酶(ALP)、护骨因子(OPG)水平,以及生活质量包括生理功能、心理功能、日常活动、社会功能评分均明显高于对照组(P<0.05);观察组不良反应发生率为15.22%,与对照组的8.70%相当(P>0.05)。结论金天格胶囊用于手部骨折术后辅助治疗,能促进骨折愈合,改善骨代谢指标水平,提高患者的生活质量。     

Study of Efficacy and the Comparison Between 2.0?mm Locking Plating System and 2.0?mm Standard Plating System in Mandibular Fractures

Purpose

The purpose of this study was to evaluate the efficacy and comparison between 2.0 mm locking plate system and 2.0 mm Champy’s titanium mini plating system in mandible fractures.

Materials and Methods

A total of 20 patients with mandibular fractures were selected and divided into two groups A and B on randomized basis. Group A was treated with open reduction internal fixation using 2.0 mm locking plates and group B with 2.0 mm Champy’s titanium miniplates. All patients were followed up for 12 weeks postoperatively.

Results

Results of the study show less screw loosening, less precision in plate adaptation and less alteration of the osseous or occlusal relationship upon screw tightening in group A. Chi square test was applied to compare the results between the two groups. Statistical analysis did not show significant difference of incidence of malocclusion between the two groups (p value = 0.606). Statistical analysis using un-paired t test showed significant difference of working time between the two groups (p value = 0.00296). When comparing the overall complication rates according to plates used, the χ² test showed no statistically significant difference between the locking and nonlocking plates (p > 0.05).

Conclusion

It is observed in our study that the locking plate/screw system offers significant advantages over the conventional plating system. The precise adaptation required for using conventional plates is not needed when this locking plate/screw system is used. Locking plate/screw system provides better stability than the conventional plate/screw system.
