Additional bedtime H2‐receptor antagonist for the control of nocturnal gastric acid breakthrough: A Cochrane systematic review

OBJECTIVES: To assess the effectiveness and safety of additional bedtime H₂‐receptor antagonists (H₂RAs) in suppressing nocturnal gastric acid breakthrough (NAB) via a systematic review. METHODS: Eligible trials were identified by searching the Cochrane Central Register of Controlled Trials (CENTRAL) (Cochrane Library Issue 2, 2004), MEDLINE (January 1966–June 2004), EMBASE (January 1980–June 2004) and CINAHL (January 1982–June 2004). Additional hand‐searching was conducted on the proceedings of correlated conferences, eight important Chinese journals and references of all included trials. All randomized controlled trials evaluating H₂RAs for the control of NAB were eligible for inclusion. The systematic review was conducted using methods recommended by The Cochrane Collaboration. RESULTS: Only two randomized crossover studies, comprising 32 participants, met the inclusion criteria. Because the design, dosage and duration of the treatments were different between the studies, it was not possible to conduct meta‐analysis. There were no consistent conclusions found between the two included studies in evaluating H₂RAs for the control of NAB. CONCLUSIONS: No implications for practice at this stage can be concluded. Appropriately designed large‐scale randomized controlled trials with long‐term follow up are needed to determine the effects of additional bedtime H₂RAs in suppressing NAB.     

螺旋CT导引下肺部肿瘤射频热消融治疗的应用研究

目的 通过对肺肿瘤射频热消融（RFA）治疗效果的观察，评价其技术特点、安全性和疗效。方法 30例肺肿瘤患者共46个肿瘤接受了RFA治疗（其中肺部原发性肿瘤20例，转移瘤10例），在CT引导下将消融电极刺入到距肿瘤边缘组织1cm处，根据病灶大小，将子针打开至合适直径，达到靶温度后，持续7～15min。对患者进行1～9个月的随访，通过胸部X线片和增强螺旋CT观察治疗效果。结果 30例患者46个肿瘤，共做消融灶123个，治疗区域坏死率为100％。（1）随访1个月30例，46个肿瘤瘤体完全消融41个，占89.13％；部分消融5个，占10.87％。（2）随访3～9个月26例，40个肿瘤病灶完全缓解（CR）33个，部分缓解（PR）4个，无变化（NC）2个，进展（PD）1个，总有效率达925％（37／40）。结论 RFA治疗肺部肿瘤疗效肯定、安全，是1种应用前景较好的方法。     

浮肩损伤的临床特征和治疗

目的 总结浮肩损伤（floating shoulder injury，FSI）的临床特征和治疗效果。方法1993年1月-2004年9月收治浮肩损伤患者8例，除2例行锁骨固定带固定外，其余6例均行手术治疗，其中单纯行锁骨切开复位重建钢板内固定1例，同时行肩胛骨内固定5例。受伤至手术时间为2h～7d，平均3．5d，术后6个月对患肩功能进行Constant评分判定疗效，并对浮肩损伤的临床特征和治疗进行总结。结果6例患者经过6个月～3年（平均11个月）的随访，锁骨和肩胛骨骨折均愈合，肩关节活动范围无明显受限，但有2例患者在举重物时肩关节有轻度的疼痛，1例患侧上肢肌力较对侧稍减弱。术后6个月患肩功能Constant评分平均为93分。结论浮肩损伤多为高能量暴力所致的不稳定性肩胛带损伤，在治疗方案上尚存争议。但对移位明显的浮肩损伤以及有伴发伤的浮肩损伤进行手术治疗是必要的。     

卵巢子宫内膜异位囊肿粘连程度及相关因素分析

Objective To investigate the relationship between degree of endometrioma adhesions and clinical feature, surgical treatment and postoperative recurrence. Methods From Jan 2003 to Mar 2008, 662 patients with endometrioma undergoing laparoscopic ovarian endometrioma excision in Peking Union Medical College Hospital were studied retrospectively. All patients were classified into four groups according to the extent of adhesions: 31 cases in none adhesions group, 123 cases in mild adhesions group (filmy thickness, avascular, easily separated adhesions), 310 cases in moderate adhesions group (less than a half of ovary was adjacent to dense thickness adhesions which was difficult to separate, or above a half of ovary were adjacent to filmy thickness adhesions) and 198 cases in severe adhesions group (above a half of ovary was adjacent to dense thickness, well vascularized adhesions which was difficult to separate, and always involved the other pelvic organs, observed angiogenesis). The comparison of degree, characteristics, period of pain, lab test, surgical management and postoperative recurrence was performed among those above groups. In the mean time, risk factors and multinomial logistic regression were analyzed. Results (1)Clinical characteristics: The incidence of patients with dysmenorrhea, dyspareunia, straining feeling in anus, chronic pelvic pain and the level of CA125 (>35 kU/L) was remarkably higher in moderate-to-severe adhesion groups than in none-to-mild adhesions groups (P=0.000, 0.000, 0.001, 0.006 and 0.000, respectively). Infertility rate were significantly higher in severe adhesions group(15.7%,31/198) than none adhesions group(3.2%,1/31), mild adhesions group(11.4%,14/123) and moderate adhesions group(9.7%,30/310, OR=1.728, P<0.05).(2)Operating time and blood loss: Operating time of each groups was as followed: (37±15) min in none adhesions group, (42±19) min in mild adhesions group, (50±20) min in moderate adhesions group and (63±22) min in severe adhesion group. Blood loss was (23±12) ml in none adhesion group, (31±27) ml in mild adhesion group, (40±32) ml in moderate adhesion group and (70±67) ml in severe adhesions group. Thicker adhesions result in longer operation time and more blood loss. (3)Combined with other disease: The ratio of patients who combined with adenomyosis or deeply infiltrating endometriosis in moderate-to-severer adhesion groups was higher than patients in none-to-mild adhesions groups (OR=3.466, P=0.000). (4) Postoperative recurrence: It was categorized into recurrence of pain and cyst. Moderate-to-severe adhesions was related to higher recurrence rate of pain (OR=1.685,P=0.046), but was irrelevant to recurrence of cyst. Conclusion The more extent of endometrioma adhesions was related to severer pelvic pain symptoms, longer operating time and more blood loss. Postoperative pain recurrence rate was observed in moderate-to-severe adhesion group. Extent of adhesions was irrelevant to cyst recurrence.

骨质疏松相关基因的研究进展

骨质疏松(osteoporosis,OP)在很大程度上受基因的影响。在OP的相关基因中,维生素D受体(VDR)基因、雌激素受体(ER)基因、Ⅰ型胶原基因及转化生长因子基因都是重要的候选基因。VDR基因中BB基因型者比Bb及bb基因型者的腰椎骨密度(bone mineral density,BMD)低,骨丢失率高。FokⅠ基因型与腰椎BMD降低有明显相关性,ff基因型者腰椎BMDXx基因型者>xx基因型者。Ⅰ型胶原基因与骨量呈显著相关性,COLIA1基因突变可致低骨量、骨脆性增加。转化生长因子β(TGF-β)基因对调节骨形成和骨吸收有重要作用,TGF-β基因中可发生碱基丢失,这种变异多见于OP患者。
