股骨远端C3型骨折行对侧髂骨取骨有利于膝关节早期康复训练

目的研究对侧髂骨取骨与同侧取骨相比是否会对股骨远端C3型骨折术后膝关节功能康复产生影响。 方法按照纳入、排除标准,前瞻性纳入自2013年4月至2015年7月手术治疗股骨远端C3型骨折的病例,按照手术侧与髂骨取骨侧是否相同,分为同侧取骨组、对侧取骨组。分析两组患者的手术耗时;术后患侧膝关节主动伸直达到10°、屈曲达到120°的时间间隔;术后3个月末髂骨取骨区的疼痛视觉模拟评分(VAS);记录随访期内取骨区出现切口红肿、切口延迟愈合、血肿、感染、髂嵴撕脱骨折等情况。计量资料采用t检验或秩和检验,计数资料采用卡方检验,术后患侧膝关节主动伸直达到10°、屈曲达到120°的时间间隔采用Kaplan-Meier法进行生存分析,行Breslow检验。 结果共纳入同侧取骨组12例、对侧取骨组11例,同侧取骨组随访中位时间18(14,21)个月,对侧取骨组随访中位时间15(13,20)个月。对侧取骨组手术耗时(t＝2.169,P<0.05)、术后膝关节主动伸直达到10°、屈曲达到120°的预期时间(χ²＝7.999,P<0.05;χ²＝9.325,P<0.05)、取骨区疼痛减轻程度(t＝8.910,P<0.01)都优于同侧取骨组。术后同侧、对侧取骨组分别出现1例、2例取骨处切口红肿,予以对症治疗后好转、痊愈;所有患者随访期内均未发生取骨区血肿、感染、髂嵴撕脱骨折。 结论股骨远端C3型骨折行对侧髂骨取骨有利于膝关节早期康复训练。     

Obstetric complications and transition to psychosis in an "ultra" high risk sample

OBJECTIVE: An association between birth and pregnancy complications and the later development of schizophrenia has been described for decades and obstetric complications (OCs) have been proposed as a vulnerability marker for psychosis in line with the neurodevelopmental hypothesis of psychotic disorders. Previous studies of OCs have focused on established schizophrenia. In this study, the association between OCs and the development of psychotic disorder was studied in a group of 74 young people identified as being at very high risk for the first onset of psychosis. METHOD: The "ultra" high risk (UHR) cohort was identified by the presence of subthreshold psychotic symptoms, or a combination of first-degree relative with a psychotic disorder and recent functional decline. Thirty-eight per cent of the cohort developed an acute psychotic episode over the 12-month period after recruitment. As a component of a larger research study, the level of OCs experienced by the UHR cohort was assessed at intake. RESULTS: Obstetric complications were not associated with the later development of psychosis in the UHR group included in this study. CONCLUSIONS: This study does not support a role for OCs as a risk factor for the later development of psychosis; however, we cannot conclude that they should be completely ignored as a candidate risk factor for onset of psychosis. A number of weaknesses of the study suggest that it may be premature to dismiss OCs as a risk factor for the development of psychosis and further research is urged in this area.     

Expression of class I MHC molecule,HSP70 and TAP in human hepatocellular carcinoma

AIM: To demonstrate whether class I MHC molecule, transporter associated with antigen processing (TAP), and heat-shock proteion70 (HSP70) expressed in liver cancer cells before the design and construction of CTL vaccine against hepatocellular carcinoma (HCC). METHODS: We studied 30 HCC specimens by labeled streptavidin biotin (LSAB) method of immunohistochemistry. RESULTS: The results showed that the majority of HCC cells investigated naturally expressed class I MHC and TAP, which were different from other tumor cells. Furthermore, we found that HSP70 expressed not only in cellular cytoplasm, but also on the cell surface in HCC. CONCLUSION: Our findings indicate that our understanding about immune escape mechanisms employed by HCC cells may be further improved. It is important to design and construct CTL vaccine against HCC.

姜黄素防治急性胰腺炎的作用机制研究进展

急性胰腺炎是常见的临床急性腹部疾病,其起病急、进展迅速、结局不良,限制炎症发展是急性胰腺炎治疗的有效策略。姜黄素是一种来自姜黄的黄色素,具有抗纤维化、抗癌、抗细胞凋亡和抗炎等多种活性。姜黄素可通过抑制核因子-κB(NF-κB)相关通路的活性,调控丝裂原活化蛋白激酶（MAPK）信号通路,抑制Janus激酶2(JAK2)/信号转导及转录激活蛋白3(STAT3)信号通路,激活肌醇磷脂-3-激酶（PI3K）/丝氨酸-苏氨酸激酶（Akt）信号通路,抑制炎症因子分泌,抑制趋化因子上皮中性粒细胞激活肽78(ENA-78)的表达,抑制环氧化酶2(COX-2)的表达,改善细胞自噬功能,抑制胰腺星状细胞活化,减轻氧化应激反应,发挥防治急性胰腺炎的作用。综述了姜黄素防治急性胰腺炎的作用机制,以期为姜黄素的临床研究提供参考。
