Once uveal melanoma (UM) has distant metastasis, the median survival time of the patient is less than 12 months. There is currently a lack of standard treatment for metastatic UM. In recent years, immunotherapy is splendid in the field of oncology. Immune checkpoint therapy, cancer vaccine therapy and T cell adoptive therapy have been applied to UM therapy. However, most of the clinical effects are limited and the survival benefit is not high. The recent early research results of the new immunotherapeutic drug IMCgp100 are encouraging.

Abstract: Beginning with 4-level quality control measures of clinical research in traditional Chinese medicine (TCM), we elaborated the implementation process and demands of quality control measures of each level, including quality control, monitoring, auditing, and inspection. On the basis of joint inspection experience of 41 projects of the "Prevention and Treatment of Difficult and Complicated Diseases of TCM" plan of the "11th Five-year National Key Technology R&D Program", we analyzed the ensuring effect of 4-level quality control system and joint inspection model, and then pointed out the existing problems in the executing process of quality control system at different levels and joint inspection model. Finally we investigated what should be revised in the quality control system and joint inspection model, thus providing the theoretical support for quality inspection improvement of TCM clinical research.

[Objective]To investigate the relationship of baseline antimullerian hormone(AMH)and live birth rate of IVF/ICSI and further explore the prognostic effect of AMH on live birth rate.[Methods]All non-polycystic ovary patients who underwent their first embryo transfers in our unit and had basal serum AMH evaluated between 2010 and 2015 were evaluated in this retrospective study. Patients were grouped according to their AMH level,i.e. low AMH group with AMH less than 1.1 ng/mL(n = 485),middle AMH group with AMH between 1.1 ng/mL and 7.0 ng/mL (n = 1 989),and high AMH group with AMH higher than 7.0 ng/mL (n=468). For age subgroup analysis,patients were stratified as follow:group A(age≤29 years),group B(30~34 years),group C(35~39 years)and group D(over 40 years). We compared clinical outcomes between AMH groups in different age groups usingunivariate and multivariate analysis. ROC analysis was utilized to assess predictive value of AMH on live birth rate.[Results](1)In both fresh and frozen embryo transfers,baseline AMH was significantly related to clinical outcomes. The lower AMH was,the lower implantation rate,clinical pregnancy rate,and live birth rate. However,higher miscarriage rate was observed. All difference reached statistically significant.(2)In age subgroup analysis,we demonstrated AMH was related to live birth rate in patients in group A,B, and C,regardless of fresh or frozen embryo transferred. In those over 40 years,AMH was related to live birth rate in frozen cycles (P < 0.05)but not fresh cycles(P = 0.092). The further multivariate analysis confirmed the above results after controlling po?tential confounding variables.(3)The AUC of ROC analysis for AMH predicting live birth rate were 0.647,0.633 for fresh and fro?zen cycles respectively.[Conclusion]Baseline AMH as one of excellent ovarian reserve markers ,was significantly related to live birth rate in fresh or frozen cycles. Baseline AMH was an independent prognostic factor of live birth rate,but its predictive value on live birth rate was of limited clinical value.

OBJECTIVETo explore various factors affecting the clinical pregnancy outcomes of artificial insemination with donor sperm (AID).
METHODSWe retrospectively analyzed 15,744 cycles of AID in 6302 women and investigated the association of the clinical pregnancy outcomes of AID with the treatment protocols, the times of insemination per cycle, the age of the infertile women, the status of the oviduct, and the number of AID cycles.
RESULTSThe pregnancy rate of AID was higher in the chlomiphene-treated women than in those of the natural cycle group (P = 0.003) but showed no significant differences either between the chloramiphene and human menopause gonadotropin (HMG) or between the HMG and natural cycle groups (P > 0.05), and so was it in the women that had received AID twice per cycle before and after ovulation (26.3%) than in those that had undergone only once before (7.0%) or after ovulation (23.7%) (P < 0.05). However, the pregnancy rate was remarkably lower in the women aged 35-40 years (16.5%), especially in those over 40 years (1.2%), than in those under 35 years (26.0%) (P < 0.05). There was no significant difference in the success rate of AID between the women with oviductal adhesion and those without (27.4% vs. 28.1%, P > 0.05). The pregnancy rate of the first cycle of AID (27.6%) was markedly higher than those of the second (24.7%), third (23.9%), and fourth (23.1%) (P < 0.01), but with no significant differences among the latter three cycles (P > 0.05), while that of the fifth cycle (19.0%) was remarkably lower than those of the first four (P < 0.01).
CONCLUSIONThe age of the infertile women is an important factor affecting the success rate of AID. AID twice per cycle is better than once only. For those without oviductal factors, at least 4 cycles of AID are required before in vitro fertilization.

ABSTRACT: Data management has significant impact on the quality control of clinical studies. Every clinical study should have a data management plan to provide overall work instructions and ensure that all of these tasks are completed according to the Good Clinical Data Management Practice (GCDMP). Meanwhile, the data management plan (DMP) is an auditable document requested by regulatory inspectors and must be written in a manner that is realistic and of high quality. The significance of DMP, the minimum standards and the best practices provided by GCDMP, the main contents of DMP based on electronic data capture (EDC) and some key factors of DMP influencing the quality of clinical study were elaborated in this paper. Specifically, DMP generally consists of 15 parts, namely, the approval page, the protocol summary, role and training, timelines, database design, creation, maintenance and security, data entry, data validation, quality control and quality assurance, the management of external data, serious adverse event data reconciliation, coding, database lock, data management reports, the communication plan and the abbreviated terms. Among them, the following three parts are regarded as the key factors: designing a standardized database of the clinical study, entering data in time and cleansing data efficiently. In the last part of this article, the authors also analyzed the problems in clinical research of traditional Chinese medicine using the EDC system and put forward some suggestions for improvement.

BACKGROUND:Currently, the study of total hip arthroplasty in elderly is more. Perioperative treatment and postoperative rehabilitation are increasingly perfect, but the study of middle-aged total hip arthroplasty is less, especialy long curative effect in postoperative and long-term folow-up stil has many problems to be solved. In China, there are few studies addressing how to select the prosthesis during total hip arthroplasty in middle-aged patients, which kind or material of prosthesis is better, so the evidence for clinical application is less. OBJECTIVE:To compare and analyze the repair effects of bone cement total hip arthroplasty and uncemented total hip arthroplasty in middle-aged patients. METHODS:A total of 60 middle-aged patients who received total hip arthroplasty in the Department of Orthopedics, Xinjiang Uygur Autonomous Region Chinese Medicine Hospital from January 2005 to January 2008 were folowed up for 5 years. Their mean age was (37±6) years. There were 32 cases undergoing uncemented total hip arthroplasty and 28 cases receiving bone cement total hip arthroplasty. At 6 months, 2 and 5 years after replacement, Harris score for recovery of limb function and imaging findings were compared and analyzed. RESULTS AND CONCLUSION: Harris score for recovery of limb function was significantly better in the uncemented total hip arthroplasty group than in the bone cement total hip arthroplasty group at 6 months, 2 and 5 years after replacement (P < 0.01). No complications were found at 6 months in the uncemented total hip arthroplasty group, but one case affected osteolysis at 2 years and two cases experienced prosthesis loosing at 5 years after arthroplasty. In the bone cement total hip arthroplasty group, two cases had osteolysis and one case had prosthesis loosing at 6 months after arthroplasty, three cases had prosthesis loosing at 2 years, and two cases affected linear permeability dissolvement at 5 years after arthroplasty. These findings suggest that uncemented prosthesis achieved a high rate of functional restoration and a low rate of complications in middle-aged patients. Uncemented total hip arthroplasty had satisfactory clinical and radiographic outcomes at a minimum of 5-year folow-up.
