It is advocated on clinical medical education to let students contact clinical diagnosis and treatment earlier, visiting more patients and promoting the ratio of visitation and course. But as more and more students flood into university, clinical visitation has turned into a difficulty to improve students' ability. To resolve this problem, we have made some efficient practice and exploration.

Objective We aimed to investigate the role of McMaster model of family therapy in improving family function of patients with advanced hepatocellular carcinoma (HCC).Methods Patients who had advanced HCC and received transarterial embolization (TAE) or transarterial chemoembolization (TACE) from Department of Hepatobiliary Ⅰ,Eastern Hepatobiliary Surgery Hospital between October 1,2012 and June 25,2013 were randomly divided into two groups:the experimental group (51 patients) and the control group (49 patients).The control group received routine family support education.The experimental group not only executed routine family support education,but also was given McMaster model of family therapy according to evaluation results of family assessment device (FAD) on the second and third day of hospitalization.The status of family function of all patients were assessed by FAD on the fnrst day of hospitalization and fourth week after therapy.We compared the status of family function between the two groups.Results In age,gender,educational level,place of residence,occupation,family economic status,medical payment,liver or kidney function,HBV infection,cirrhosis and tumor burden,no statistical differences were found between the experimental group and the control group patients before TAE or TACE.Two groups were dysfunction in communication,roles,affective responsiveness,affective involvement,behavior control,and general function in addition to problem solving before TAE or TACE.No statistical differences were found between two groups.After the therapy,compared with the control group,those patients in the experimental group had a lower level scoring in communication,roles,affective responsiveness,affective involvement,behavior control,and general function in addition to problem solving on the fourth week after the therapy,t value was-2.544,-3.767,-3.904,-2.848,-4.950 and-4.953,the difference had statistical significance.Conclusions McMaster model of family therapy may help to improve family function of patients with advanced HCC.

Objective To investigate the imaging features of the juxta-artieular bone cyst (intraosseous ganglia). Methods The imaging findings of 54 cases histopathologically confirmed were studied retrospectively. X-ray, CT, and MRI were performed in 46 eases,30 cases, and 14 cases, respectively.Results Of the 54 cases, 27 arised from the ankle (including multiple lesions), 16 from the knee joint,7 from the hip joint, 1 from the proximate end of the humerus, ulna, trapezium bone, the first phalange in each, and 1 from the talus and the distal end of the tibia. There were 43 eases (44 lesions) in the ankle and knee joints, with 29 (65.9%) lesions located in the medial articular surface. Fifty-four eases had thinning sclerotic rim, showing a unilocular round osteolytic appearance in 44 cases and a muhiloculated-cystic appearance with septa in 10 cases. Discontinuous articular surface were seen in 15 cases, articular surface collapse in 1, gas density in 3 and fluid-fluid plane in 1. (1) On x-ray films, 46 cases (47 lesions) with well-defined sclerotic rim revealed round, arch or irregular lyric areas at the adjacent articular surface. The fissures were found at the adjacent articular surface in 6 lesions. No joint spaces were abnormal. (2)On CT,30 cases with sclerotic rim showed round in 19 lesions, arch in 3, and irregular in 8. The fissures were seen at the adjacent articular surface in 14 lesions. The density showed homogeneous in 27 lesions, and gas existed in 3. (3) Fourteen cases (15 lesions)showed hypointense to isointense signal on MR T1 Wl and hyperintense signal on T2WI. Fluid- fluid plane was found in 1 ease. The fissures were observed at the adjacent articular surface in 8 lesions. 7 cases showed swelling soft tissue. Conclusion The characteristic locations combined with the typical imaging features may suggest the diagnosis of jaxta-articular bone cyst.

Objective To explore the effect of general intervention in improving the psychological condition of healthy pregnant women. Methods Totally 96 pregnant women who made prenatal visits in our obstetrics and outpatient department were divided into the control and the intervention group stochasti-cally. The intervention group started from first prenatal visit. The general intervention measures included cognitive intervention, the behavioral intervention, family coping intervention and psychological intervention with self-designed relaxation exercises. While conventional prenatal visit, propaganda and nursing were im-plemented to the control group.Self-made general questionnaire and symptom checklist 90 (SCL-90)were used to survey and analyze the results. Results Post-natal depression and anxiety of the control group was obviously higher than that of the prenatal. The Post-natal obsessive-compulsive symptom, interpersonal sensitivity, depression, hostility, terror and bigotry in the intervention group were greatly alleviated. Com-pared with the control group, obsessive-compulsive symptom, interpersonal sensitivity, depression, hostility and terror of the intervention group were significantly different (P<0.05). The depression improved while the difference was not evidently differenL Conclusions Delivery had great influence on the psychological status of women,especially anxiety and depression. General intervention measures like psychological relax-ation exercises can improve the psychological condition of healthy pregnant women obviously,especially de-pression.

Objective To investigate histopathological and ultrastructural differences between melasma tissues and normal skin tissues around pigmented nevus. Methods Eight patients with melasma and 16 patients with facial pigmented nevus were included in this study. Two millimeter punch biopsies were taken from melasma lesions and adjacent normal skin of facial pigmented nevus. Biopsy specimens were then subjected to hematoxylin?eosin (HE) staining, Fonton?Masson staining, Verhoeff?van Gieson staining, and immunohistochemical staining with monoclonal antibodies HMB45 and NKI/beteb. Transmission electron microscopy was used to observe the tissue specimens. Semi?quantitative analysis was performed under a light microscope, and quantitative analysis by using a computerized image analysis system. Results Histopathological study revealed increased number of melanin granules mainly in the basal and prickle cell layers, sometimes in the dermis, in melasma tissues compared with normal skin tissues. Melanocytes were only observed in the epidermis of melasma tissues. Compared with normal skin tissues, melasma tissues showed no significant difference in the quantity of melanocytes, but a significant increase in the volume, staining intensity and dendrite number of melanocytes. In all of the 8 patients with melasma, mild to moderate lymphocytic infiltration was observed in the superficial dermis and around capillaries, with moderate telangiectasis in the superficial dermis. Electron microscopy revealed that there were more melanosomes in melanocytes and keratinocytes, and melanocyte dendrites extended into the dermis in melasma tissues. Conclusions Among the 8 patients, there were only two types of melasma, i.e., epidermal melasma and mixed melasma, and no dermal melasma was found. Inflammation and telangiectasis may induce or aggravate melasma.

ObjectiveTo study the effects of 9 different drying methods on total saponin content and antioxidant capacity ofParis polyphylla var.yunnanensis.Methods UV-VIS spectrophotometry was used for measuring the total saponin content ofP. polyphylla var.yunnanensis, 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis (3-ethylbenzthiozoline-6)-sulphonic acid (ABTS+) radical scavenging methods were used for evaluating the antioxidant capacity ofP. polyphylla var. yunnanensisextracts.ResultsThe total saponin contents ofP. polyphylla var.yunnanensis dried by different methods existed significant difference. The sample dried at 35℃ showed highest total saponin content (17.557 mg/g). The sample dried in the shade naturally showed middle total saponin content (13.740 mg/g). Based on the results of antioxidant capacity detected by two methods, the samples ofP. polyphylla var. yunnanensis dried by 9 different methods all showed good antioxidant capacity and showed a certain concentration dependence.Conclusion The samples dried at 35℃ have the highest antioxidant capacity. Therefore, drying at 35℃ is a better drying method to obtain high quality and high activity ofP. polyphylla var.yunnanensis.
