Recent researches have shown that resectable pancreatic cancer can benefit from post-operative adjuvant chemoradiation, regardless its surgical margins, tumor size, lymph node involvement and the level of cell differentiation. Several phase Ⅱ clinical trials indicated a good tolerance to preoperative chemoradiation. Although there is no gold standard for treating locally advanced unresectable pancreatic cancer, gemcitabine-based chemotherapy or chemoradiation therapy can increase survival rate compared with best supportive care.

The factors impacting the pregnancy rate and the live birth rate mainly include ovary function disorder and low endometrial receptivity, which can cause the difficulty in embryo implantation, early miscarriage and pregnancy failure. In recent years, researchers of the traditional Chinese medicine (TCM) have made active efforts in assisting IVF-ET, so as to achieve a great advance in improving the ovary reaction, treating the ovarian hyperstimulation syndrome (OHSS), improving the follicle, embryo quality and endometrial receptivity and protecting the fetus, which had been summarized in this article.

Objective To explore the early clinical characteristics of multiple system atrophy (MSA) in the elderly,and provide the basis for early diagnosis.Methods Totally 102 cases with probable MSA in elderly patients were retrospectively analyzed to understand the beginning symptom,clinical features and assistant examination results,combined with the literature review.Results Among the 102 cases diagnosed as probable MSA (61 cases were male and 41 cases were female),57cases (55.9％) were diagnosed as parkinsonism dominant MSA (MSA-P) subtype and 45 cases (44.1％) as cerebellar dominant MSA (MSA-C)subtype.In the beginning symptom,27 cases appeared autonomic dysfunction,including 15 cases (26.3％) in MSA P subtype and 12 cases (26.6％) MSA-C subtype; 14 cases manifested as dysuresia,11 cases as orthostatic hypotension,and 8 cases as sexual dysfunction.Parkinsonism as the beginning symptom was in 49 cases,among whom 24 cases were of abnormal gait,3 cases of resting tremor,16 cases of muscle rigidity,and 15 cases of slowed movement.Cerebellar symptoms as the beginning symptom were in 33 cases,with gait and limb ataxia of 27 cases,dysarthria of 6 cases,nystagmus of 2 cases.Pyramidal tract signs as the beginning symptom were in 2 cases.There was early misdiagnosis of 36 cases (35.3％).Conclusions As wide variety of early clinical features,MSA can be easily misdiagnosed.The clinical features and assistant examination should be paid attention to improvement of the accuracy of early diagnosis.

Liver volume can reflect the change of parenchyma volume and functional reserve of liver.Liver volumetry is commonly achieved by imaging methods such as ultrasound,CT and MRI,while CT volumetry is most commonly used in clinical practice.This article discussed the decision making among different liver volumetry methods and associated applications in hepatectomy.

BACKGROUND:With respect to mesenchymal stem cels from other sources, synovial mesenchymal stem cels are rich in source, and moreover, the synovial tissue can regenerate quickly after partial hepatectomy and lead to fewer complications, in recent year, which have become a hot spot in stem cel research. OBJECTIVE:To observe the proliferation and directional differentiation of synovial mesenchymal stem cels from osteoarthritis patients. METHODS:Synovial mesenchymal stem cels were isolated and cultured. MTT assay was used to detect cel proliferation ability. Alkaline phosphatase activity was detected quantitatively at 7 days of osteogenic induction, and osteogensis-related gene expression was measured at 7, 14, 21 days of osteogenic induction. Alizarin red staining was performed at 21 days of induction. RESULTS AND CONCLUSION:(1) Passage 3 synovial mesenchymal stem cels proliferated faster, which were in latent period at 1, 2 days after inoculation, in logarithmic growth phase at 3-6 days, and then entered into the plateau phase at 7 days. (2) The activity of alkaline phosphatase was significantly higher in the induction group than the control group at 3, 7, 10 days after osteogenic induction (P < 0.05). The cels were positive for alizarin red staining at 21 days of osteogenic induction, and there were calcium deposits and calcium nodules in the extracelular matrix. (3) Bone-binding protein and Runx2 were visible at 7 days of osteogenic induction, and reached the peak at 21 days. These findings indicate that synovial mesenchymal stem cels from patients with advanced osteoarthritis have strong proliferation ability, which can differentiate into osteoblasts under in vitro induction.

Objective To develop a fixed ruler for the simulated locator to measure the distance between human organs.Methods Analyses were carried out on the problems of the existing measures of the simulated locator and clinical requirements,and then the matching of the ruler with the locator and etc were explored.The structures of the fixing hole and slots were determined,and the ruler base was selected.The ruler was composed of an organic glass plate with multi slots and multi cylindrical copper wires.Results At the isocenter of the locator,the fixed scale values of the ruler equaled to those of the ruler on the screen,and the values for multi point distances could be obtained with the fixed ruler and stored in medical image.Conclusion The fixed ruler measures the distance between human organs simply and accurately,and lays a foundation for the development of likely product.
