OBJECTIVE:To study the liver damage mechanism in mice caused by the incompatibility of Daphne genkwa com-bined with Glycyrrhiza uralensis in aspect of liver transporter. METHODS:40 mice were equally randomized into a normal control (isometric normal saline)group,a group of G. uralensis [15 g(medicinal matierias)/kg],a group of D. genkwa [15 g(medicinal tatierias)/kg],a group of D. genkwa with G. uralensis in the ratio of 1∶1 [15 g(crude drug)/kg],a group of D. genkwa with G. uralensis in the ratio of 1∶3 [15 g(medicinal matierias)/kg](n=8). The mice were given the corresponding drug,ig,once a day for 7 consecutive days. HE staining was performed and then the pathomorphology of liver tissues were observed under the light mi-croscope,and calculation was made for pathological grading. Western blot method was employed to determine the protein expre-ssion of the transporter Ntcp protein in the livers of mice. The contents of total bile acids(TBA)in livers of mice were determined. RESULTS:Compared to the mice in the normal control group,those in the group of 1∶1 and 1∶3 demonstrated higher protein ex-pression of Ntcp. In the group of 1∶1,the mice with grade“+++”hepatocyte degeneration were more (8). The mice with grade“+++”and“++”hepatocyte degeneration in the groups of 1∶3 were more (2 and 8 respectively). CONCLUSIONS:D. genkwa combined with G. uralensis can induce liver damage in mice by a mechanism which may be related to the accumulation of a large amount of TBA in the liver as a result of the increase in the expression of Ntcp in mice.

The Medline and CNKI databases were searched with the key words of radiation-induced myocardial damage,damage pathway,pathogenesis,and intervention,and 37 articles were obtained.The pathogenesis of radiation-induced myocardial damage may be related to various mechanisms such as oxidative stress,transforming growth factor-β,renin-angiotensin system,mast cells,and endothelial dysfunction.The pathogenesis of radiation-induced myocardial damage is a complex process involving various mechanisms,and currently,there are ongoing studies on the cellular and molecular mechanisms involved in its pathogenesis and interventions.

Purpose: To report 2 cases of papillary thyroid carcinoma occurring in a thyroglossal duct remnant, and to discuss the diagnostic and therapeutic methods by reviewing the literature. Methods: An asymptomatic midline mass occurring in the upper neck was the sole presenting complaint in 2 cases. The preoperative evaluation included a complete head and neck examination, B-ultra sound examination and FNAB. The Sistrunk procedure was done. A lobectomy( case 1) and a lumpectomy ( case 2) were performed respectively, because of the abnormality found in their thyroid gland. A modified neck dissection was performed in case 2 because of regional lymphadenopathy. The following histologic studies were carried out on tissues with HE stain. Results: Diagnoses of thyroglossal duct carcinoma were made by several pathologists. Tissues from thyroid were first diagnosed as nodular goiter in case 1 and thyroid adenoma in case 2. In case 2, one positive lymph node and invasion to the hyoid bone was found. Conclusions: Malignant lesions are rare in the thyroglossal duct remnant. The diagnostic criteria is acknowledged. Resection of the thyroglossal duct carcinoma by the Sistrunk procedure is an adequate surgical approach. But the controversy about further treatment will continue because of the lack of large series of patients and the 10 to 20 year follow-up.

Comrade LU Zhi-jun, a famous surgeon and acupuncture expert, was a leading cadre in health field with outstanding achievements, and a leader of western medicine doctors learning traditional Chinese medicine in the Chinese Communist Party, and also he was a main establisher of The China Academy of Chinese Medical Sciences and a founder of TCM scientific researches and integrated Chinese and western medicine in new China. The present paper reviews the course of LU Zhi-jun in learning and applying acupuncture and moxibustion therapy and a part of works carried out in faithfully implementing our party's policies for uniting Chinese and Western medicine, and in development of TCM including acupuncture and moxibustion in past tens years.

This paper reports the nursing care of 12 patients with idiopathic scoliosis treated with halo-pelvic traction preoperatively which focused on breathing training, traction frame management. One patient suffered from temporary brachial plexus injury and four cases suffered from superior mesenteric artery syndrome. With 14-21 day's traction and nursing care, the correction rate of Cobb angle was 35%-50%,the forced vital capacity was improved by 25%,and all the patients received orthomorphia surgery in time. It is suggested that the patients with severe idiopathic scoliosis treated by halo-pelvic traction could take out-of-bed activity freely. It could not only relieve pain and reduce mental pressure, but also improve the safety of orthomorphia surgery.

Objective To observe the clinical effect of gemcitabine combined with nedaplatin concurrent chemotherapy and radiotherapy in treatment of advanced nasopharyngeal carcinoma.Methods Seventy-six advanced nasopharyngeal carcinoma patients were divided into observation group(38 cases)and control group(38 cases)by radom digits table.The patients in observation group were treated with gemcitabine combined with nedaplatin concurrent chemotherapy and radiotherapy.The patients in control group were treated with fluorouracil combined with cisplatin concurrent chemotherapy and radiotherapy.The clinical effect and adverse reaction were compared between two groups.Results The total effective rate in observation group was 84.2％(32/38),which significantly higher than that in control group[60.5％(23/38)](P＜0.05).There was no significant difference in 1 year overall survival rate between two groups[89.5％ (34/38)vs.76.3％(29/38)](P ＞ 0.05).The rate of gastrointestinal reactions and oral ulcers in observation group were 42.1％(16/38)and 7.9％(3/38),which significantly lower than those in control group[73.7％ (28/38),31.6％(12/38)](P ＜ 0.05).The rate of bone marrow suppression between two groups had no significant difference[31.6％(12/38)vs.23.7％(9/38)](P ＞ 0.05).Conclusion Gemcitabine combined with nedaplatin concurrent chemotherapy and radiotherapy in treatment of advanced nasopharyngeal carcinoma can enhance the clinical effect,and decrease the adverse reaction,which can be applied in clinic.

Objective To investigate the pain-relieving effectiveness of persistent epidural anesthesia and its influence on mothers and infants.Methods 40 pregnant women without any obstetric complications and anesthetic contraindications were selected as the observation group,and persistent epidural anesthesia were applied when the cervicis opened to be larger than 3cm.40 cases with similar obstetric conditions were regarded as the control group without using any anesthesia.We compared the degree of labor pain,duration,delivery mode,the incidence of postpartum hemorrhage,intrauterine distress,neonatal asphyxia between the two groups.Results There were significantly difference in the rate of oxytocin utilization,vaginal delivery and the time of stageⅡ labor.There were no obvious difference in the active phase of labor course,the incidence of cesarean birth,intrauterine distress,neonatal asphyxia and postpartum hemorrhage between the two groups.Conclusions The results indicate that epidural anesthesia could affect the length of stageⅡ labor time and have merits of simple,obvious analgetic effect,but inflecencing delivery mode,therefore it to be improve.
