【摘要】 目的 了解住院白血病患者的社会支持状况。 方法 采用相关“社会支持评定量表”，调查分析2010年8-11月80例住院白血病患者的社会支持状况。 结果 白血病患者获得的社会支持为（42.34±7.04）分，支持度较高，与常模（34.56±3.74）分比较差异有统计学意义（Plt;0.01），无配偶及医疗自费患者所获得的社会支持相对较低。 结论 医护人员在临床中应注意拓宽住院白血病患者的社会支持渠道，帮助患者保持较高的社会支持水平，从而促进康复，提高生活质量。【Abstract】 Objective To explore the social support condition of the inpatients with leukemia. Methods According to “Social Support Assessment Inventory”, the social support conditions of 80 patients with leukemia who were hospitalized between August and November, 2010 were analyzed. Results The total score of social support was 42.34±7.04 in inpatients with leukemia, and 34.56±3.74 in normal controls; the difference was significant (Plt;0.01). The patients who remained single or had no medical insurance obtained less social support. Conclusions Nurses should help patients with leukemia keep in a moderate high level of social support to promote the recovery of patients and improve their quality of life.
目的 探讨胶质母细胞瘤中基质金属蛋白酶7（MMP-7）的表达及其与患者术后生存期之间相关性。 方法 采用免疫组织化学法检测60例胶质母细胞瘤组织标本中MMP-7的表达，统计分析其表达强弱与患者术后生存期之间的关系。 结果 MMP-7在胶质母细胞瘤中总表达率为73.3%，强表达组生存期明显短于弱表达组（χ2=7.043，P=0.008）。 结论 MMP-7可以作为胶质母细胞瘤预后的重要因素之一。
ObjectiveTo compare the short-term effectiveness of unicompartmental knee arthroplasty (UKA) and high tibial osteotomy (HTO) in the treatment of medial compartment osteoarthritis (OA) of the knee so as to provide a reference for clinical selection of appropriate treatment. MethodsBetween January 2010 and June 2011, 28 cases of medial compartment OA of the knee underwent UKA in 16 cases (UKA group) and HTO in 12 cases (HTO group). Biomet Oxford phase Ⅲ unicompartmental knee prosthesis was used in UKA group, and closing wedge osteotomy in HTO group. There was no significant difference in gender, age, course of disease, side, body mass index, articular cartilage degeneration classification, preoperative knee range of motion (ROM), Lysholm knee score, Tegner activity score, and femorotibial angle (FTA) between the 2 groups (P>0.05). The patients of UKA group began weight-bearing walking with walking aids within 48 hours after operation, and the patients of HTO group began weight-bearing walking with walking aids at 6 weeks after operation, and gradually began full weight-bearing walking at 8-12 weeks. ResultsThere was no significant difference in operation time and intraoperative blood loss between 2 groups (t=0.406, P=0.688; t=-1.552, P=0.133). All incision healed primarily in both groups. No complications occurred in 2 groups. All patients were followed up 3.5 years on average (range, 3.0-4.5 years) in UKA group and 3.6 years on average (range, 3-4 years) in HTO group. There were significant differences in Lysholm knee score, Tegner activity score, and FTA in the 2 groups between before and after operation (P<0.05), but there was no significant difference in knee ROM (P>0.05). At last follow-up, there was no significant difference in all above indexes between 2 groups (P>0.05). The postoperative X-ray showed that all force lines of the lower limbs were corrected, and the prosthesis and internal fixation were fixed reliably. During follow-up, Kellgren-Lawrence Ⅱ degeneration of the lateral compartment was observed in 1 case of 2 groups respectively; Kellgren-Lawrence Ⅱ degeneration of the patellofemoral joint was observed in 1 case of the HTO group, there was no significant difference between the 2 groups (χ2=0.778, P=0.378). ConclusionBoth UKA and HTO have good short-term effectiveness for treating unicompartmental OA; however, the long-term effectiveness need further study and follow-up.
Objective To establish a new method for detection of β-glucuronidase (β-G) mRNA in human liver and kidney tissues. Methods β-G mRNA expression was detected by reverse transcription polymerase chain reaction(RT-PCR) in 10 cases of normal liver tissues, 10 cases of normal kidney tissues and 8 cases of hepatocellular carcinoma tissues. Results The expand products of β-G mRNA were expressed in liver and kidney tissues with similar size of 422 bp. The expression contents of β-G mRNA in liver and kidney normal tissues were different (1.71±0.32 vs 1.83±0.22) but without statistical significance (Pgt;0.05). However, the expression content of β-G mRNA in hepatocellular carcinoma tissues was 3.88±0.86， which was significantly higher (P＜0.01) than that in normal liver tissues. Conclusion β-G mRNA determination is feasible by checking β-G gene alignment in gene bank and designing draw matter in the tissue of liver and kidney. It may be very significant to explore the change of β-G mRNA in various tissues in studying of molecular mechanism.
Objective To investigate the effect of cholecystectomy on the induction of large intestine cancer and its mechanism. Methods After cholecystectomy, the large intestine neoplasm in mice was induced with dimethylhydrazine(DMH).The histogenesis and growth pattern of large intestine cancer were observed.The Sphase fraction (SPF) of epithelium cells in large intestine mucosa was determined using flow cytometry. Before and after operation, the feces of mice were collected to determine the cholic acid (CA), chenodeoxycholic acid (CDCA), deoxycholic acid (DCA) and lithocholic acid (LCA) concentration by highperformance liquid chromatography. Results The average number of large intestine neoplasms per mouse,percentage of large intestine adenomas in examined mice and SPF of experimental group were significantly higher than those of control group (P＜0.05). The fecal LCA concentration in postcholecystectomy was significantly higher than that in precholecystectomy and in sham operation group (P=0.00). Conclusion The large intestine neoplasm of mice induced by DMH is increased and the proliferation of epithelium cell in large intestine mucosa is increased after cholecystectomy. This suggests that cholecystectomy has promoting effect on induction of large intestine neoplasm in mice. The gut may deal with the increased secondary bile acid(LCA) concentration postcholecystectomy.
Abstract: Percutaneous balloon pulmonary valvuloplasty (PBPV) has become the first choice for the treatment of pulmonary valve stenosis (PS). PBPV is used not only in the independent way to relieve Milo-Ⅰ amp; Ⅱ type of PS as an alteration of surgery, but also in the combination way with surgical treatment to some multiple or complex congenital heart defect,where it plays a part as a pre-operative appeasement or a co-operative procedure, even a supplementary expedience to some failed surgery post-operatively. In this paper, the anatomic classification of PS, the usage of ultrasounic examination, the indication and contraindication, the method and skill during operation, and the effect evaluation of PBPV are reviewed.
