METHODS:HPLC was performed on the column of Agilent Zorbax-C18 with mobile phase of acetonitrile-1%formic acid aqueous solution(gradient elution)at flow rate of 1.0 ml/min,the internal standard was puera-rin,detection wavelength was 280 nm,column temperature was 25 ℃ and sample volume was 10 μl. RESULTS:There was a lin-ear range between linear ranges and peak area of 8 ingredients(r≥0.999 0);RSDs of within-day and inter-day precision tests were no more than 1.9%,repeatability tests was no more than 7.3%;average recoveries were in the range of 92.73%-112.37%(RSD=3.2%-8.2%,n=6);and average matrix effects were 90.33%-105.78%(RSD=3.2%-8.0%,n=6). CONCLUSIONS:The method is rapid,sensitive and specific,and can be used to the simultaneous determination of the contents of 8 ingredients of Shuan-ghuanglian freeze-dried powder in placental perfusate.

Lapareseopic colectomy is commonly performed,but laparoscopic extended right hemicolectomy with D3 lymphadenectomy for cancer located at hepatic flexure of the colon is a complex procedure,even in the hands of experts.Laparoscopic dissection of the lymph nodes around the middle colonic and right gastroepiploic vessels are so complicated that precise vascular anatomy and surgical plane are essential to complete this procedure safely.We herein describe a standard technique for performing laparoscopic extended right hemicolectomy with D3 lymphadenectomy using a medial-to-lateral approach.The main surgical plane of this procedure is the right Toldt's space.The superior mesenteric vein (SMV) is the most important anatomical landmark of vascular dissection.Medial-to-lateral approach makes it easy to locate the right Toldt's space and the SMV.

Patient′s expectation has been defined as the anticipation that given events were likely to occur during, or as an outcome of, health care. What people expect from their health care are potentially important in predicting patient satisfaction and dissatisfaction with their care, treatment and health outcomes. There was widespread recognition of the importance of evaluating services from consumer perspectives. In this article, domestic and foreign research in recent years, expectations status, significance and various influencing factors in relation to the expectations in processes of health care were summarized. Consumer evaluations of their health care are now an established component of quality assessment, planners need to understand the expectations underlying patients′views in order to interpret their feedback. Thus leading to improve patient satisfaction and the social evaluation of medical units.

Objective To assess effects of cerebral ischemic postconditioning(IPost)on neuronal apoptosis and phosphated glycogen synthase kinase-3β(GSK-3β)after cerebral ischemic/reperfusion.Methods The experiment was conducted at the center for animal experiment of Renmin Hospital,Wuhan University.Thirty male Wistar rats were randomly divided into three groups:sham operation(S),ischemic/reperfusion(I/R)and ischemic postconditioning(IPost).Each group contained ten rats.Global brain ischemia was produced with four-VO method.Animals were killed after two days.Apoptosis in neurons in the cortex region were detected by TUNEL assay; infarct areas were detected by TTC ; activity of p-GSK-3β was detected by spectrum assay; Statistical software SPSS13.0 was applicated to perform one-way ANOVA Student-Newman-Keul test; correlation was detected by linear regression.Results Compared with group S,TUNEL-positive cells and infarct areas increased(P ＜0.01),the activity of p-GSK-3β decreased in I/R and IPost groups(P ＜ 0.01).Compared with group I/R,TUNEL-positive cells and infarct areas significantly decreased(P ＜ 0.01),the activity of p-GSK-3β increased in group IPost(P ＜ 0.01).The activity of p-GSK-3β and TUNEL-positive cells had highly correlation,so as infarct areas(P ＜ 0.01).Conclusions IPost can lessen the ischemic/reperfusion injury of Cortex,through increas the activity of p-GSK-3[β and decreasing neuronal apoptosis.

Objective To analyze the cosmetic effects and postoperative complications of patients with early breast cancer who underwent oncoplastic breast-conserving reconstruction and traditional breast-conserving surgery.Methods From January 201 2 to October 201 5,we collected a total of 67 patients with early-stage breast cancer who underwent breast-conserving surgery in Affiliated Mindong Hospital of Fujian Medical Univer-sity.Thirty patients who underwent oncoplastic breast-conserving reconstruction were in observation group,and 37 patients who underwent traditional breast-conserving surgery were in the control group.The postoperative complications,cosmetic effects and survival situations in the two groups were compared.Results In the aes-thetic effects evaluation,22 patients (73.33%)and 1 6 patients (43.24%)had good or excellent cosmetic effects,6 patients (20.00%)and 1 4 patients (37.84%)had general cosmetic effects,2 patients (6.67%) and 7 patients (1 8.92%)had poor cosmetic effects in the observation group and control group,with a signifi-cant difference (Z =-2.51 3,P =0.01 2).Four patients (1 3.33%)in the observation group had postopera-tive complications,including that 1 patients had incisional dehiscence followed by incisional wound infection and skin necrosis,and 3 patients had subcutaneous exudates.However,2 patients (5.41 %)in the control group had postoperative complications,including 1 patients with incisional dehiscence,and 1 patients with inci-sional wound infection.There were no significant difference in the occurrence rates of postoperative complica-tions in the two groups (χ2 =0.490,P =0.484).The mean follow-up period was 28 months.We found 1 patients of local recurrence,and 2 patients of metastases in the control group.However,all patients were free of recurrence and metastases in the observation group,with no significant difference (P =0.1 40).Conclusion Oncoplastic surgical technique in the breast-conserving surgery for patients with early-stage breast cancer is a safe and effective procedure,with highly satisfactory cosmetic effects for the majority of patients,which is worth to recommend.

Embryo damage refers to the pregnancy early embryonic development stops for some reason, and dead fetus in the womb is not yet out. It is clinical common refractory disease in the department of gynecology, and the current prevalence showed significantly increased trend. It had become a high-profil important reproductive health problem, and the research of early diagnosis and treatment scheme for embryo damage was great significance. In this paper, through the summary of the early diagnosis and treatment scheme for embryo damage, we hope that it can provide powerful help for the early detection and treatment of embryo damage and lies a foundation to promote reproductive health.

0.05).After treatment,blood serum E2 level in group M was (74.18?22.32) pmol?L-1,whereas that in group D was (24.96?3.94)pmol?L-1,there was significant difference(P0.05).Conclusion Clinical symptoms of patients with recurrent endometriosis in two groups are improved.Serum E2 level in group M remains in the follicular phase,but group D declines to postmenopausal range.Mifepristone does not result in lack of estrogen,ovulation recovers rapidly after treatment in group M compared with group D.Mifepristone and danazol have not obvious impact on blood serum cortisol.

Objective:To provide policy recommendations for Beijing public health departments to grasp the dy-namic allocation of healthcare resources and the advantage of medical functional dispersal, and making appropriate health policies to rationally adjust the allocation of health resources. Methods:To study the dynamic function of Bei-jing medical, this study uses the method of accounting of cases summary of the annual report on health finance through the descriptive analysis of the gross fixed capital formation in various regional government-run health facili-ties. Results:The results of this study show that the quality of medical health administrative resources was higher, but effectively dispersed in 2015. By contrast, the basic public health resources allocation was unbalanced. Conclu-sion:This study puts forward the corresponding health policy suggestions. On one hand, it is important to make fur-ther policy to encourage high quality medical resources to be effectively relieved and the regional planning should be done according to market demand by avoiding the blind construction at the early stages. On the other hand, much at-tention should be paid on the balanced development of the basic public health service ability and the coordinated de-velopment of administrative capacity in health, and supporting policies should be formulated, which should rationally allocate the public health resources for a better overall medical functional dispersal.

Objective To discuss the MRI features and pathogenic mechanisms of lung cancer intramedullary spinal cord metastasis (ISCM). Methods Four cases with clinically and 3 cases pathologically proved lung cancer ISCM were analyzed retrospectively. Turbo spin-echo sequence T 1 and T 2 weighted images were acquired in all patients. T 1 weighted images were obtained after intravenous administration of Gd-DTPA in all patients. Results A total of 7 ISCM were displayed by MR studies. The tumor occurred in thoracic cord (3/7) and in medullary cone (4/7). The tumor involved the central aspect of the cord. The lung cancer ISCM showed hypointensity (n=1) or isointensity (n=6) on T 1WI and hyperintensity on T 2WI. The extensive cord enlargement with cyst formation or syringomyelia was common. On contrast study, all tumors showed marked homogenous enhancement with clear borders. Conclusion The lung cancer ISCM usually presented as solitary lesions with marked contrast enhancement. The extensive cord enlargement was common in all patients. Because of the limitation in the evaluation of lung cancer ISCM on MRI, definite diagnosis of lung cancer ISCM depended on combination of clinical and MRI data.
