开放式鼓室成形术治疗胆脂瘤型中耳炎21例临床观察

目的：探讨开放式鼓室成形术治疗胆脂瘤型中耳炎的疗效,为临床治疗提供依据。方法：随机选取2009年1月至2012年1月在我院应用开放式鼓室成形术（乳突根治伴鼓室成形术）治疗胆脂瘤型中耳炎的患者21例,对其临床资料以及手术方式进行回顾性分析。结果：治疗后,本组21例患者中18例移植筋膜完全成活,2例发生鼓膜再穿孔,1例鼓膜内陷、复发流脓,所有患者全部干耳。术后对患者听力进行纯音测试,其中10例听力提高10dB,7例听力提高15-20dB,1例听力提高25-30dB,3例听力未见变化。结论：对胆脂瘤型中耳炎患者行开放式鼓室成形术,在对中耳病变、乳突进行彻底清除的前提下,可使中耳内的炎症得到消除、通气功能得到恢复,从而起到根治的效果。因此,开放式鼓室成形术不仅能有效防止胆脂瘤的复发,还能显著提高患者听力,具有较高的应用价值,值得临床推广运用。     

小型猪急性心肌梗死后心力衰竭模型的构建

目的研究开放拉长塑料细管法（OPS）对HBV转基因小鼠（P21^HBxPHBx）和白内障小鼠（cataract mice,cM）胚胎冷冻效果。方法采用乙二醇作为冷冻保护剂,以昆明小鼠为对照,用OPS法对CM及P21^HBxPHBx两种小鼠3．5d的胚胎进行玻璃化冷冻,并比较KM、CM及P21^HBxPHBx获得胚胎数,解冻后胚胎的复苏率及发育率。结果KM、CM及P21^HBxPHBx小鼠平均获得胚胎数分别为31．12、19．32、9．14枚;解冻后的复苏率分别为95．6％、79-3％、80．3％;发育率分别为94．7％、73．8％、56．6％。表明HBV转基因小鼠的获得胚胎数明显低于昆明小鼠,解冻后三种小鼠的胚胎复苏率之间无显著差别,而解冻后发育率,P21^HBxPHBx小鼠要明显低于KM小鼠。结论转基因小鼠超排数及解冻后发育率低于昆明小鼠,而白内障模型小鼠和昆明小鼠比较不显著。

Dental arch changes after anterior open bite treatment in the mixed dentition produced by miniscrew-supported palatal crib vs conventional fixed palatal crib:: A randomized clinical trial

ObjectivesTo evaluate the dental arch changes produced by the miniscrew-supported palatal crib (MSPC) and the conventional fixed palatal crib (CFPC) after the treatment of patients with anterior open bite (AOB) attributed to the tongue-thrusting habit in the mixed dentition stage.Materials and MethodsA total of 26 children aged 8 to 11 years with an AOB were randomly distributed into two equal groups; the MSPC group was treated using a palatal crib supported by two miniscrews inserted paramedially, whereas the CFPC group was treated using a conventional fixed palatal crib soldered to bands. Digital models were obtained pretreatment and after a follow-up duration of 9 months.ResultsThe MSPC group included 12 participants (9 girls and 3 boys; mean age, 9.4 ± 0.75 years), and the CFPC group included 12 participants (10 girls and 2 boys; mean age, 9.0 ± 0.73 years). The amount of AOB closure was similar in both groups: 3.97 ± 1.44 mm in the MSPC group and 3.97 ± 0.89 mm in the CFPC group. There was significant mesial movement of the maxillary first molar in the CFPC (−1.42 ± 0.99 mm) compared with the MSPC group (−0.53 ± 0.32 mm).ConclusionsBoth appliances resulted in similar improvement in the amount of AOB closure. There was significantly more mesial movement of the maxillary first molars in the CFPC group compared with the MSPC group.     

老年腹股沟疝特点及手术方式研究进展

老年腹股沟疝因其腹壁肌薄弱且常伴合并症,且最佳手术方式尚无统一结论。局麻下行Lichtenstein术由于操作简单、经济、术后并发症少,广受术者推崇;腹腔镜应用于老年腹股沟疝也被证实是安全、有效的,其中,腹腔镜腹膜前修补术（TAPP）可方便、无创地发现隐匿疝并同时进行修补;腹腔镜全腹膜外修补术（TEP）由于不进入腹腔,有效减少对老年病人腹腔脏器的干扰。老年腹股沟疝手术治疗方法各有特点,术者应就病人本身特点及对各种术式的掌握来选择最佳方式,以减少手术并发症及复发率。

Feasibility of open chest management with modified negative pressure wound therapy immediately after cardiac surgery

OBJECTIVESTo evaluate the feasibility of open chest management with our modified negative pressure wound therapy immediately after cardiac surgery as a therapy for atypical tamponade.METHODSOpen chest with modified negative pressure wound therapy was performed immediately after cardiac surgery. The surface of the heart and the vessels were covered with non-adherent siliconized gauze. The sternal halves were stented using edge-cut disposable syringes to maintain a larger mediastinal cavity. Approximately 45 mm of distance was kept between the sternal edges. A trimmed sterile polyvinyl foam sponge was inserted into the mediastinum, the entire wound was sealed and negative pressure (−50 to −75 mmHg) was applied using a suction generator. Delayed chest closure was performed in a standard manner once the haemodynamic status was stabilizsed.RESULTSThe mortality rate was 3/15 (20%) patients. Deep sternal wound infection occurred in 1/15 (6.7%) patients. Five patients were extubated during the open chest management. Sternal closure was delayed for median of 3 days after the initial surgery. There was no incidence of bleeding complications or need for additional haemostatic procedures.CONCLUSIONSNegative pressure wound therapy performed immediately after cardiac surgery was feasible in our small number of patients.Clinical registration numberStudy ID: 2020-149.
