目的 探讨川芎嗪对链脲佐菌素(STZ)诱导2型糖尿病大鼠肾病的治疗作用及机制。方法 SD大鼠50只,随机分为正常组和模型组。除正常组外,其余大鼠均给予高脂-高糖饲料喂养4周,再给予链脲佐菌素(40 mg/kg,ip),72 h后测定空腹血糖,将血糖值高于16.67 mmol/L的大鼠随机分成4个组即模型组,二甲双胍阳性组(250 mg/kg),川芎嗪低、高剂量组(80、160 mg/kg),连续给予相应试药8周。其中正常组和模型组的大鼠均给予同等量蒸馏水灌胃。实验结束时,测定大鼠血糖、尿蛋白、血尿素氮和血肌酐含量;免疫组化法测定大鼠肾组织TLR4和caspase3蛋白表达。光镜下观察肾脏病理学变化。结果 与模型组比较,二甲双胍组和川芎嗪高剂量组给药8周后,大鼠动态空腹血糖均能明显降低(P<0.05),大鼠动态尿蛋白显著性降低(P<0.01,P<0.05); 二甲双胍和高剂量组TLR4和caspase3蛋白表达明显低于模型组(P<0.05);肾脏组织病理性损伤明显减轻。结论 川芎嗪对STZ诱导2型糖尿病大鼠肾病具有保护作用,其机制可能与下调TLR4表达作用有关。

Objective To investigate the therapeutic effects and mechanisms of tetramethylpyrazine (TMP) on streptozocin(STZ)-induced-nephropathy in type 2 diabetic rats. Methods 50 SD rats were randomly divided into normal group(n=10) and model group(n=40). The model rats were fed on high fat and sugar diets for 4 weeks, then given STZ(40 mg/kg,ip). After 72 hours, the fasting blood glucose (FBG) was measured. Rats with high FBG above 16.67mmol/L were randomly divided into four groups: model, metformin(Met, 250 mg/kg)and TMP (80 mg/kg, 160 mg/kg) groups for treating 8 weeks, and both the control and model groups were given equals distilled water by intragastric administration. At the end of the experiment, blood glucose, urine protein, blood urea nitrogen and creatinine were measured. The expression of TLR4 and caspase3 protein in kidney tissue of rats was determined by immunohistochemistry. Pathological changes of kidney were observed under light microscope. Results Compared with the model group, metformin and high dose of TMP administered after 8 weeks, rats can significantly reduce the dynamic fasting blood glucose(P<0.05). Urinary protein excretion of total dynamic decreased significantly (P<0.01, P<0.05); the protein expression of TLR4 and caspase3 in the metformin group and high dose group was significantly lower than that in the model group (P<0.05); kidney tissue pathological damage was significantly reduced. Conclusion TMP has a protective effect on STZ induced nephropathy in type 2 diabetic rats, and its mechanism may be related to the down-regulation of TLR4 expression.

目的 探索长链非编码RNA LINC00672在肺癌组织中的表达及其与患者预后的关系。方法 采用实时荧光定量PCR技术检测LINC00672在75对肺癌组织和癌旁正常组织中的表达,分析其在癌组织中的表达水平与肺癌患者临床分期和预后的关联。结果 LINC00672在肺癌组织中的表达显著低于癌旁正常组织(P=0.026),LINC00672高表达与低表达相比能显著降低肺癌患者的死亡率(死亡风险比=0.46;95%置信区间=0.23~0.95;P=0.036),延长患者中位生存期(34个月 vs 18个月,P=0.027)。并且,LINC00672与肺癌预后的关联在低年龄组(<60 a)、吸烟者和非饮酒者中更为显著。进一步相乘交互作用分析显示LINCOO672与饮酒在肺癌死亡风险上具有显著的交互效应(P=0.049)。然而,LINC00672的表达水平在不同分期、T、N、M患者来源的肺癌组织中的表达无显著性差异。结论 LINC00672与肺癌发生发展存在关联,可用于预测肺癌患者的预后。

Objective To explore the expression status of long non-coding RNA LINC00672 in lung cancer tissues and its correlation with survival of lung cancer. Methods We applied the real-time PCR method to measure the expression level of LINC00672 in 53 pairs of lung cancer tissues and adjacent lung normal tissues, and analyzed the correlation between its expression and survival of lung cancer. Results LINC00672 was significantly down-regulated in lung cancer tissues than their adjacent lung normal tissues (P=0.026). Compared to those with low expression level of LINC00672, patients with high expression level of LINC00672 exerted a significant long median survival time than those with low expression level (34 vs 18 months, P=0.027). High LINC00672 expression also contributed to low mortality rate than low LINC00672 expression (hazard ratio=0.46, 95% confidence interval =0.23-0.95, P=0.036). Meanwhile, the correlation was more evident in those low age groups (< 60 years), smokers and non-drinkers. There was also a significant interaction between LINC00672 and drinking on affecting death risk of lung cancer. However, no significant association was observed between LINC00672 expression and clinical stages as well as T, N, M status. Conclusion LINC00672 is correlated with development of lung cancer, which may be a valuable biomarker to predict lung cancer prognosis.

Objective To investigate the expression and clinical significance of PBK in prostate cancer. Methods Using tissue microarrays of prostate cancer, which including 98 cases of prostate cancer and 81 cases of normal tissue adjacent to cancer as the research object, the expression of PBK was detected by immunohistochemistry, and statistical analysis was used to analyze the relationship between the expression of PBK and the clinicopathological features of prostate cancer in the microarray and Taylor database. Results The expression of PBK in prostate cancer was significantly higher (P=0.001), and the expression increased in the group of high Gleason score (P=0.001). The Taylor database obtained similar results, and Kaplan-Meier analysis showed that PBK was significantly correlated with the biochemical recurrence free survival (P=0.007). Finally, Cox regression model was used to analyze the prognostic factors of prostate cancer. Result shows that, the high expression of PBK (P=0.041), Gleason score and pathological stage were independent predictors of biochemical recurrence of prostate cancer. Conclusion The expression of PBK is closely related to prostate cancer, and can be used as a molecular marker for clinical diagnosis and treatment.

成人急性呼吸窘迫综合征死亡率居高不下,而当前治疗手段大多以对症支持为主且效果欠佳。通过早期识别ARDS高危患者,及早施加干预措施阻断疾病进展是目前研究的新方向。较之传统机械通气模式,气道压力释放通气因其特有的肺保护作用备受国内外学者关注,APRV下肺泡持续开放并保持稳定可减少肺损伤发生,将APRV应用于ARDS预防理论上前景可观,本文将围绕早期实施APRV对预防ARDS应用价值展开论述。

The mortality of adult acute respiratory distress syndrome(ARDS) remains high. Supportive care measures are main treatments to ARDS currently while the effect is poor. Early application of airway pressure release ventilation in patients who are at high risk for ARDS is a new direction of research. Compared with traditional mechanical ventilation, more and more scholars both at home and abroad pay attention to the airway pressure release ventilation APRV because of its unique lung protection. Under APRV the alveoli maintain stable continuously which may reduce the incidence of lung injury. Applying APRV to ARDS prevention is promising theoretically. This paper will focus on the value of preemptive airway pressure ventilation for high-risk ARDS patients.

环孢素A(cyclosporin A,环孢素A)是强效的免疫抑制剂,常用于抑制器官移植后的排斥反应,器官移植后新发糖尿病与免疫抑制剂的使用有关。除器官移植,环孢素A还被用于治疗其他自身免疫性疾病,例如1型糖尿病。但环孢素A对胰岛β细胞和其他多种器官有毒副作用,长期使用环孢素A会导致胰岛素抵抗和胰岛β细胞功能损伤,这也是器官移植后糖尿病(post-transplant dibetes mellitus,PTDM)的主要原因。因此在糖尿病领域环孢素A的使用需要对病情进行具体分析和仔细斟酌。

Cyclosporin A (CsA) is a powerful immunosuppressant that is widely used to prevent organ rejection and to treat several autoimmune diseases, such as type 1 diabetes mellitus. Post-transplant diabetes mellitus (PTDM) is related with immunosuppressant. Moreover, there are many toxicity and side effects of CsA on pancreatic β cell and other organs, Long-term treatment of CsA may cause insulin resistance and β cell dyfunction. That's the main reason for post-transplant dibetes mellitus (PTDM). In diabetes mellitus fields, CsA must be used carefully considered.
