ZnCuInS/ZnS(QDs)量子点是一种不含重金属半导体的纳米材料,以无机前驱体和非配位溶剂为基础,合成得到尺寸为3.2nm的ZnCuInS/ZnS核壳量子点,通过测量ZnCuInS/ZnS量子点光致发光光谱,其发射峰波长约为700nm,半宽度为110nm。同时,以GaN蓝... ZnCuInS/ZnS(QDs)量子点是一种不含重金属半导体的纳米材料,以无机前驱体和非配位溶剂为基础,合成得到尺寸为3.2nm的ZnCuInS/ZnS核壳量子点,通过测量ZnCuInS/ZnS量子点光致发光光谱,其发射峰波长约为700nm,半宽度为110nm。同时,以GaN蓝光芯片为基础,制备了ZnCuInS/ZnS量子点荧光粉LED发光二极管,并对其发光特性进行了研究。在恰当的偏置电压下,逐渐改变滴涂在底层为蓝色GaN LED芯片上的ZnCuInS/ZnS量子点溶液浓度,观察到红光逐渐增强,随之蓝光逐渐减弱,其发射光CIE色坐标发生改变,并可以得到较好的红光光谱。 展开更多

Summary: Evidence-based medicine is advocated by WHO and adopted by developed countries for many years. In China, however, the selection of essential medicine and various medical insurance reimbursement schemes medicine is usually based on experts' experience of prescription practice which is under heavy critics resulting from the lack of related comparative efficacy and evidence-based research. The efficacy of Jian'ganle in prevention of drug-induced liver injury (DILI) caused by antituberculotics was evaluated in this study by comparison with Hugan Pian, glucuronolactone and reduced glutathione. Evidence was provided for relevant sectors such as Ministry for Human Resources and Social Security of the People's Republic of China and National Health and Family Planning Commission of the Peo- ple's Republic of China to select and renew the Essential Medicine List (EML), the new rural cooperative medical scheme in China (NRCMS) list or the reimbursement list of industrial injury insurance. A total of 189 patients with initial pulmonary tuberculosis were divided into four groups who took antituberculotics combined with Jian'ganle, Hugan Pian, glucuronolactone and reduced glutathione respectively. Their liver function profile including alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL), direct bilirubin (DBIL), total protein (TP), albumin (A) and globulin (G) were detected at admission as baseline and after treatment. The Jian'ganle group was compared with the three others by chi-square tests. In an aspect of maintaining bilirubin indexes normal, Jian'ganle was more efficacious than glucuronolactone. And Jian'ganle had a little more efficacy than reduced glutathione to maintain protein indexes normal as well. And the therapeutic regimen of antituberculotics combined with Jian'ganle was the best in treating tuberculosis and preventing DILI at the same time. The study showed that among the four hepatinicas which demonstrated similar prevention of DILI caused by antituberculotics, Jian'ganle has more advantages over the three others to some extent, which provides a reliable basis for health sectors to select and renew the EML, NRCMS List or the reimbursement list of industrial injury insurance. 展开更多

Objective: To observe the therapeutic effect on hepatic fibrosis of chronic hepatitis B by Chinese medicine Handan Ganle capsule (HDGLC).Methods: A total of 104 patients with chronic hepatitis B has been treated by HDGLC for 6 months, liver fibrosis indexes and the serum biochemical indexes were detected before treatment, during the curative period and by the end of treatment. Hepatic biopsy was performed before or after the treatment.Results: The improvement rate of clinical symptoms was 79.0%-90.6%, and the recovery rate of ALT was 72.6%, serum fibrosis indexes such as HA, type Ⅳ collagen and LN were significantly decreased along with the extending course of disease ( P <0.05). The pathohistological score of liver was decreased from 7.82±6.22 before treatment to 5.16±3.75 after treatment ( P <0.05) and the score of hepatic fibrosis was decreased from 7.49±5.45 before treatment to 5.16±4.26 after treatment ( P <0.05).Conclusion: HDGLC has remarkable therapeutic and reversing effect on chronic hepatitis B induced hepatic fibrosis. 展开更多
