Male Wistar rats were performed 70% partial hepatectomy (PH) or 1.5mg/g body weight D-galactosamine injection (Gal) intraperitoneally. From the 1st to the 7th day after treatment, the serum concentration of alpha-fetoprotein (AFP) and albumin (ALB) was measured and the liver sections were stained with routine and immunohistochemical methods and observed with light and electron microscopy. The mitotic index (MI) reached a maximum level (1.5%) on the 2nd day after PH, while the Gal group showed a lower (0.8%) and delayed (on the 3rd day) MI peak. On the 2nd and 3rd day after PH, AFP positive hepatocytes were predominantly observed in the periportal area and ALB positive cells mainly distributed around the central veins. In Gal group, AFP was detected both in hepatocytes near the necrotic areas and particularly in some special small cells which had not been seen in PH group. These small cells seemed to be able to transform into typical hepatocytes. Intracellular localization of AFP and ALB was observed in the perinuclear space, RER, and Golgi complex. Serum AFP and ALB levels in both groups presented reciprocal changes from the 1st to the 7th day after treatment.

General education is the quality education of higher education , which includes the humanities , so-cial science and natural science .It point out the present status of medical colleges and universities to carry out the general education of humanities and the existing problems which based on the current China 's higher medical colle-ges and universities to strengthen the urgency of the general education of humanities .It main including:the lack of humanistic concept of general education and human general curriculum is not reasonable ;the human general educa-tion hasn't dived into the medical professional education which lead to the students attention degree is not enough ;Human general education methods is single , practical link is weak .To solve these problems should be set up a med-ical humanities general education organization and management agencies , build reasonable medical humanities gen-eral course system , strengthen the construction of teaching staff of a curriculum , improve education curriculum teaching methods and many other countermeasures and suggestions .

According to analysis the training contents of the clinician in humanistic quality based on competen-cy, the authors put forward four optimization strategies of cultivating the humanistic quality of clinicians :the area hospital builds the competency model of uniform and combines with the specialty training content ; implements young doctor tutorial system to enhance the humanities accomplishment by mentoring teaching mode ;takes diversity training to improve training effect; well establish normative culture evaluation of linkage mechanism to check the effect.

Objective To evaluate the accuracy of preoperative MRI in the diagnosis of malformations associated with MRKH syndrome and identification of uterine endometrium to optimize the clinical management.Methods 1 8 females with primary amenor-rhea were studied with MRI performed with a 1.5T or 3.0T imager.All patients were examined in the supine position using a phased-array coil and underwent pelvic MRI.Two experienced radiologists evaluated all the examinations in consensus to assess the pres-ence,position and morphology of vagina,uterus,ovaries and any pelvic abnormalities.Results One or two rudimentary uteri were identified in 17 patients (94.4%).A total of 16 patients (88.9%)had bilateral rudimentary uteri,1 (5.6%)had unilateral rudimentary uteri(it was left sided).1 (5.6%)had no uterine remnants.4 (12.1%)of 33 uterine buds in 4 patients showed differentiation of the center of the uterus into three layer.Bilateral ovaries were present in 1 7 patients,and their shapes,sizes and signals are normal.The vagina and cervix were absent in all cases.Conclusion MRI is a useful diagnostic tool in the preoperative evaluation of MRKH syndrome and the endometrium to further optimize the treatment plan.

AIM:To study intravenous transplantation of human mesenchymal stem cells (hMSCs) on the life span and pathological change of SOD1-G93A amyotrophic lateral sclerosis (ALS) mice. METHODS:hMSCs were cultured and expanded from heparinized bone marrow cells from healthy donors and the purity and features were identified with FCM. hMSCs (3×10~6) resuspended in 0.3 mL DMEM or 0.3 mL DMEM only were injected into the tail vein of genotyped SOD1-G93A ALS mice. The mice were evaluated for signs of motor deficit with 4-point scoring system according to Weydt and the onset and life span were assessed. The pathological change was observed with Nissl staining and number of motor neuron was counted. RESULTS:The onset symptoms in untreated SOD1-G93A ALS mice appeared at (156.6±3.6) d of age and the average life span was (188.3±3.5) d. hMSCs transplantation delayed the onset of ALS type symptoms about 14 d and prolonged the life span about 18 d compared to the untreated SOD1-G93A littermates. The loss of motor neurons in untreated mice was much faster and severer than that in hMSCs transplanted mice. At 16 th week and 20 th week,motor neurons of untreated mice were significantly fewer than those of transplanted mice. β-globin gene in brain was detected in transplanted ALS mice. CONCLUSION:hMSCs migrate to central nervous system after intravenous transplantation,prolong the life span and delay the onset and motor neuron loss in SOD1-G93A ALS mice.

Objective To study the changes of life span and pathology in superoxide dismutase 1 (SOD1)-G93A mice after intracardiac transplantation of human mesenchymal stem cells (hMSCs).Methods hMSCs were isolated from bone marrow cells obtained from healthy donors and cultured.The purity and morphology were assessed by flow cytometry (FCM).hMSCs (3×10~6) resuspended in 0.2 ml DMEM was injected into the heart of 8 week-old SOD1-G93A mice.In non-transplantion control SOD1-G93A mice, only DMEM was injected.The mice were evaluated for signs of motor deficit with 4-point scoring system previously described by Weydt et al.The age of onset and life span in mice were assessed.The pathological change including number of motor neurons was investigated by Nissl staining.Immunofluorescence staining with specific human nuclear antibody was used to confirm the transplant of hMSCs in mice.Results The onset symptoms in untreated SOD1-G93A mice appeared at (156.56±3.60) days of age and the average life span was (188.32±3.51) days.hMSCs transplantation delayed the onset of ALS type symptoms about 16 days (x~2=10.888, P=0.001) and prolonged the life span about 14 days compared to the untreated SOD1-G93A littermates((202.19±4.09) days vs (188.32±3.51) days, x~2=3.917, P=0.04).The loss of motor neurons in untreated mice was earlier and more severe than in hMSCs transplanted mice.At 20 weeks, the number of motor neurons in transplanted mice was significantly higher than those in untreated mice.Human specific nuclear antigen in brain and spinal cord was detected in transplanted SOD1-G93A mice.Conclusion hMSCs can be implanted for a long-term into central nervous system by intracardiac transplantation and the transplantation can prolong life span, and delay the onset of the disease and motor neuron loss in SOD1-G93A mice.
