儿童龋齿采用改良非创伤性充填技术治疗的临床观察

目的探究在儿童龋齿的临床治疗中改良非创伤性填充技术的临床治疗效果。方法选取2012年7月-2013年12月在我科治疗的儿童龋齿患者110例作为研究对象,按照随机分组原则将龋齿患儿分为对照组和改良治疗组,各55例,其中对照组龋齿患儿采取常规的填充技术治疗,改良治疗组龋齿患儿则采用改良非创伤性的充填技术进行治疗,对比两组龋齿患儿的临床治疗效果。结果改良治疗组龋齿患儿的临床治疗成功率为98.2%,对照组龋齿患儿的临床治疗成功率为96.4%,改良治疗组的临床治疗成功率与高于对照组相比无统计学差异(P0.05);改良治疗组患儿在充填技术治疗后1年的成功率89.1%明显高于对照组74.5%,差异有统计学意义(P0.05)。改良治疗组龋齿患儿的术中疼痛比率18.2%(10/55)明显低于对照组49.1%(27/55),差异有统计学意义(P0.05)。结论在龋齿患儿的临床治疗中采用改良非创伤性充填技术治疗能够显著改善患者的临床治疗总有效率,同时降低患儿术中的疼痛比率,提升其术后随访填充成功率,值得在牙科治疗中推广应用。     

脾保留手术治疗创伤性脾破裂的临床探讨

目的：分析脾保留手术治疗创伤性脾破裂的疗效。方法选取该院2011年6月—2014年6月收治的创伤性脾破裂患者，共计56例，分为两组，各28例，对照组进行脾切除手术，研究组进行脾保留手术。结果研究组临床有效率为92.86%，对照组临床有效率为78.57%；术后并发症发生率研究组为10.71%、对照组为28.57%。结论脾保留手术治疗创伤性脾破裂的疗效显著，恢复快，并发症少，在患者伤情允许情况下优先选择脾保留术。     

创伤性膈疝21例临床分析

我院自１９８９年３月至１９９５年１０月手术治疗２１例创伤性膈疝，２１例疝愈。 发病机理与胸腹腔压力差、腹腔脏器冲击膈肌及胸腔负压有关。同时简要介绍了创伤性膈疝的诊断和治疗。     

急性创伤性膈疝误漏诊的防范

目的：探讨急性创伤性膈疝救治中误漏诊的原因及防范措施。方法：回顾总结9例急性创伤性膈疝的临床资料，重点分析误漏诊率和诊治失误的原因。结果：本组患正确、及时诊断率为22．2％。全组治愈8例，死亡例。结论：造成急性创伤性膈疝误漏诊的危险因素是：1、对本病的警惕性不高；2、对膈疝形成、发展的机制缺乏认识；3、过细的外科分工影响综合抢救质量；4、部分急性开放性膈肌损伤腹部症状体征轻微或缺如。     

外踝骨折分型及治疗方式探讨

踝关节骨折在创伤骨科中发病率较高 ,处理不当易造成关节疼痛 ,甚至创伤性关节炎。此多因早期处理中对外踝骨折及下胫腓关节分离认识不足所致［１］。本院按Ｄｅｎｉｓ -Ｗｅｂｅｒ分型［２］治疗外踝骨折 ,取得了较好疗效 ,报告如下。１临床资料１．１一般资料１９９７年８月～１９９９年８月共有外踝骨折患者５３例 ,其中男３２例 ,女２１例。年龄２１～６７岁 ,平均４１岁。致伤原因为 :车祸３０例 ,摔倒扭伤１６例 ,高处坠下７例。就诊时间为伤后１周以内。按Ｄｅｎｉｓ-Ｗｅｂｅｒ分型 :Ａ型１２例 ,Ｂ型２１例 ,Ｃ１型１１例 ,Ｃ２型…     

Changes in T .lymphocyte subsets after severe traumatic brain inJury

BACKGROUND： Besides local changes of cranial parenchymal cells, hemorrhage, etc., severe traumatic brain injuries also cause the changes of total body fluid and various functions, and the changes of lymphocytes and T lymphocyte subsets should be paid more attention to. OBJECTIVE： To reveal the changing laws of T lymphocyte subsets after severe traumatic brain injury, and compare with mild to moderate brain injury. DESIGN： A comparative observation. SETTINGS： Department of Neurosurgery, Longgang District Buji People＇s Hospital of Shenzhen City; Central Laboratory of Shenzhen Hospital of Prevention and Cure for Chronic Disease. PARTICIPANTS： All the subjects were selected from the Department of Neurosurgery, Longgang District Buji People＇s Hospital of Shenzhen City from August 2002 to August 2005. Thirty patients with severe brain injury, whose Glasgow coma score （GCS） was ≤ 8 points, were taken as the experimental group, including 21 males and 9 females, aging 16 - 62 years. Meanwhile, 30 patients with mild traumatic brain injury were taken as the control group （GCS ranged 14- 15 points）, including 18 males and 12 females, aging 15 -58 years. All the subjects were in admission at 6 hours after injury, without disease of major organs before injury Informed consents were obtained from all the patients or their relatives. METHODS： （1） The T lymphocytes and the subsets in peripheral blood were detected with immunofluorescent tricolor flow cytometry at l, 3, 7 and 14 days after injury in both groups. （2） The conditions of pulmonary infections were observed at 4 days after injury. The differences of measurement data were compared with the t test. MAIN OUTCOME MEASURES： Changes of T lymphocytes subsets at 1 - 14 days after severe and mild or moderate traumatic injury. RESULTS： Finally, 28 and 25 patients with mild to moderate traumatic brain injury, whereas 25 and 21 patients with severe traumatic brain injury were analyzed at 7 and 14 days respectively, and the missed ones died due to the development of disease. （1） Changes of T lymphocyte subsets： At 1 and 3 days after injury, CD3, CD4, CD8, CD4/CD8 began to decrease, whereas CD8 increased in the experimental group, which were very significantly different from those in the control group （t =2.77 - 3.26, P 〈 0.01）, and began to recover at 7 days, which were significantly different from those in the control group （t = 2.06 - 2.24, P 〈 0.05）, and generally recovered to the normal levels at 14 days （P 〉 0.05）. （2） Conditions of pulmonary infections： At 4 days after injury, the rate of pulmonary infection was significantly different between the experimental group and control group [73% （22/30）, 0, x2=37.29, P 〈 0.01]. CONCLUSION： Patients with severe traumatic brain injury suffer from damages of cellular immune function at early period （within 7 days）, and they are easily to be accompanied by pulmonary infections.
