[摘 要] 目的：评价口服携带HPV16 E7 shRNA和IL-12基因的重组短双歧杆菌在小鼠体内抗宫颈癌移植瘤的效果。方法：将pMG36e-E7 shRNA、pMG36e-mIL-12D质粒分别转化短双歧杆菌，经筛选鉴定并扩增获得携带HPV16 E7 shRNA和IL-12 基因的重组短双歧杆菌。通过小鼠皮下宫颈癌细胞移植建立荷瘤小鼠模型。口服重组短双歧杆菌1、7 d后，检测小鼠主要器官（心、肝、脾、肺、肾）和肿瘤组织匀浆液或血清在PYG培养基中形成的菌落数量，评价短双歧杆菌的肿瘤靶向性，以小鼠体内肿瘤生长曲线评估重组短双歧杆菌的抗肿瘤效果，通过主要器官切片H-E染色和检测荷瘤小鼠血清相关细胞因子水平评价口服重组短双歧杆菌的安全性。结果：成功制备重组短双歧杆菌和宫颈癌TC-1细胞移植瘤小鼠。7 d后，移植瘤组织匀浆液和血清的菌落数量证实短双歧杆菌具有靶向体内瘤组织的定殖能力，口服重组短双歧杆菌明显抑制荷瘤小鼠的肿瘤生长（P<0.05或P<0.01），但联合使用携带HPV16 E7 shRNA和IL-12基因的重组双歧杆菌的肿瘤抑制率与单独使用的并无显著差异，治疗后未见对荷瘤小鼠主要器官的损伤和血清中IL-12及IFN-γ的水平明显变化。结论：短双歧杆菌可用作靶向肿瘤的治疗性基因分子递送载体，其对宫颈癌移植瘤的疗效明显且安全可控。

INTRODUCTIONThis study aimed to examine the various factors associated with inpatient falls among patients with and without dementia in a hospital setting.

METHODSThis was a retrospective one-year study using data collected from Singapore General Hospital's electronic reporting system for inpatient falls.

RESULTSIn the study period, 298 patients aged ≥ 65 years fell during their hospital stay. The majority of the patients (n = 248) did not have dementia. In our study, fallers with dementia were more likely to use ambulatory aids, be visually impaired and have urinary incontinence. More patients with dementia than those without had a history of previous falls, and were placed on fall precaution with restricted freedom of movement, which at times, included restraints. However, the difference between patients who were put on restraints and those who were allowed to move freely was not statistically significant. The majority of falls in both groups occurred at the bedside. We found that fallers without dementia were more likely to fall during the morning shift, whereas fallers with dementia were more likely to fall during the night shift. Fallers with dementia were more likely to be confused at the time of the fall.

CONCLUSIONIn our study, we found that fallers with dementia were more likely to have visual impairment, have urinary incontinence, use walking aids, and to be confused and physically restrained at the time of the fall. The fallers without dementia in our study may have undiagnosed dementia.

OBJECTIVETo investigate the association of vitamin D receptor (VDR) gene polymorphisms with urolithiasis in Uyghur children from southern Xinjiang, China, and to clarify the molecular genetic mechanism for the disease.

METHODSSeventy-four Uygur children with urolithiasis (case group) and 103 healthy Uyghur children (control group) were enrolled as subjects. Polymerase chain reaction-restriction fragment length polymorphism was used to analyze the association of VDR gene FokI and ApaI polymorphisms with urolithiasis in Uyghur children from southern Xinjiang.

RESULTSThere were significant differences in FokI genotypes (FF, Ff and ff) between the case and control groups (χ2=7.818, P<0.05). The genotype Ff accounted for 58% of all genotypes in the case group, and Ff was significantly more prevalent in the case group than in the control group (P<0.05). There were no significant differences in ApaI genotypes (AA, Aa, and aa) between the case and control groups.

CONCLUSIONSThe polymorphisms of VDR gene FokI may be a suitable genetic marker for urolithiasis in Uyghur children.

ObjectiveTo investigate the effect of Qizil guliqent on gastrointestinal hormone in normal rats.MethodsThe rats in experimental groups were administered with Qizil guliqent(4g/kg,6g/kg,8g/kg ),madinglin (0.0027g/kg),and the rats in normal control group were given 0.5％ CMC-Na for twenty days.The method ELISA was used to detect the content of gastric motility(MTL),vasoactive intestinal peptide(VIP) and Gastrin(GAS) in serum of normal rats.ResultsIn comparison with normal control group,VIP increased in Qizil guliqent group(4g/kg,6g/kg) (P ＜0.05 ～P ＜ 0.01 );but MTL,GAS were not significantly changed in this group( P ＞ 0.05 ).MTL,GAS were increased in Qizil guliqent group ( 8g/kg ) and madinglin group (0.0027g/kg) ( P ＜ 0.05 ) ; but VIP was not significantiy changed in this group(P ＞ 0.05 ).ConclusionQizil guliqent could regulate gastrointestinal hormones in rats,and dose related.
