Since 1990 , 2 randomized trials and seeral obserational studies hae ealuated the benefits s risks of expectant management of seere preeclampsia at < 34 weeks of gestation 自1990年以来， 2个随机实验和一些观察性研究评价了对于妊娠小于34周的重度先兆子痫采用保守治疗的利与弊。
Further , 10 . 9 % of physical therapy group and 7 % of the surgical patients need further operation to release the fibrotic bundle which limited their neck movement 1岁以内评断保守治疗成功的幼儿，长大后仍有10 . 9 %须手术治疗；手术治疗的病例中也有7 %未能完成解决过紧的纤维化肌肉。

Methods : ultra - sounography was used in 109 cases with blunt abdominal injury within 0 . 5 ~ 3 hours , surgery operations were performed in 105 cases and the others were conservative treatment 方法109例闭合性腹部损伤患者在受伤后0 . 5 - 3小时内经超声检查，经手术治疗105例，保守治疗4例。
Methods 8 out of total 9 cases ( 9 eyes ) were treated by vitrectomy , combined with filtering bleb repairing with donated sclera and self conjunctive 方法9例（ 9眼）中， 8例行玻璃体切除联合异体巩膜修补、自体结膜瓣遮盖，其中3例在内窥镜引导下行玻璃体切除联合睫状突光凝术； 1例保守治疗。
Based on this data , the three different treatment methods ( traumatic epidural hematoma elimination , burr hole drainage , conservative therapy ) can be used in itedh 结论小儿外伤性单纯硬膜外血肿确诊主要依靠影像学资料，其治疗可采取不同的方法即开颅血肿清除术、锥颅血肿引流术及保守治疗。
Complications were noted in 4 patients : perforation in 2 cases who were cured conservativelly without ureteral stricture during 10 to 12 monthes follow up , urinary tract infection in 2 cases 发生并发症4例，其中输尿管穿孔2例，采取保守治疗痊愈，随访10 ~ 12个月未发现输尿管狭窄；泌尿系感染2例。

Conclusions : closed treatment is the better method according to the results of cost - effectiveness analysis , but more patients choosed operative treatment in fact , whose cause needed to be researched further 结论：从成本效果分析的角度，保守治疗是锁骨骨折的较佳方案，但临床并未较多地采纳，其原因值得进一步探讨。
