BACKGROUND:There are many preliminary studies on the survival, metaptosis, and correlation characteristics of human amniotic epithelial cel s after transplanted into the animals, but there are no reports on the quantitative analysis of the transplantation effect. OBJECTIVE:To make quantitative analysis on serum biochemical function of liver and the expression of human albumin in mice received passaged human amniotic epithelial cel s transplantation in spleen. METHODS:Forty nude mice were randomly divided into four groups (n=10 in each group):hepatectomy+cel transplantation 2 weeks group, hepatectomy+cel transplantation 4 weeks group, hepatectomy+normal saline group (treated with partial hepatectomy) and hepatectomy+cel transplantation group (transplanted with 0.2 mL passaged human amniotic epithelial cel s with 5×106 under spleen, and the blood were col ected at 2 and 4 weeks after transplantation). The mice in the hepatectomy+normal saline group were treated with splenic injection of 0.2 mL normal saline;the cel transplantation group did not receive hepatectomy, and transplanted with 0.2 mL passaged human amniotic epithelial cel s with 5×106 under spleen. The histological and morphological changes of the liver and spleen in each group as wel as the expressions of serum alanine aminotransferase, aspartate aminotransferase and human serum albumin in each group were detected, and the quantitative analysis of human serum albumin expression was performed. RESULTS AND CONCLUSION: There was no obvious morphological change after human amniotic epithelial cel s transplanted into the acute liver injury mice for 4 weeks, but specific cel s could be detected by histological method. The serum levels of alanine aminotransferase, aspartate aminotransferase and human serum albumin were improved obviously, and the human albumin could be detected in serum, the level of human albumin at 4 weeks after transplantation was significantly increased than 2 weeks after transplantation. Human amniotic epithelial cel s can survive for more than 4 weeks after transplanted into the liver injury mice, and can stil express partial characteristics and functions of hepatocyte-like cel s, improve the liver function, thus treating acute liver injury.

Objective To investigate the correlation between cerebral microbleed (CMB) and hemorrhage transformation (HT) after urokinase intra-arterial thrombolysis in patients with acute ischemic stroke.Methods The patients with acute cerebral infarction treated with intra-arterial urokinase were enrolled.They were divided into either an HT group or a non-HT goup according to whether they had HT or not.Conventional MRI sequences,susceptibility-weighted imaging (SWI),and CT scan were performed before procedure.CT or MRI was reexamined within 48 hours after procedure.The patients' demographic data,vascular risk factors,and the SWI sequences showed the numbers of CMB were documented in detail and they were compared and analyzed.Results A total of 62 patients were included,22 in HT group and 40 in non-HT group.Univariate analysis showed that the proportions of hypertension (81.8％ vs.57.5％ ; x2 =3.125,P =0.048),diabetes (63.6％ vs.40.0％ ; x2 =4.019,P =0.042),smoking (72.7％ vs.37.5％ ; x2 =4.971,P =0.030),and presence of CMB (x2 =5.297,P =0.018) of patients in the HT group were significantly higher than those in the non-HT group.Multivariate logistic regression analysis showed that hypertension (odds ratio [OR]1.51,95％ confidence interval [CI]1.102-2.954; P =0.028),diabetes (OR 1.48,95％ CI 1.09-2.825; P =0.039),and CMB (OR 1.867,95％ CI 1.103-3.158; P =0.020) were the independent risk factors for HT after urokinase intra-arterial thrombolysis in patients with acute ischemic stroke.Conclusions CMB was one of the independent risk factors for occurring HT after urokinase intra-arterial thrombolysis in patients with acute ischemic stroke.

BACKGROUND:Human amniotic epithelial cells(AECs)are easy to obtain and can function as ideal seed cells for cell transplantation and tissue repair.Currently,marking and tracing of human AECs remains rarely reported.OBJECTIVE:To explore the efficiency of adeno-associated virus(AAV)vector-medicated green fluorescent protein(GFP)on in vitro cultured human AECs transfection.METHODS:Human amnion samples were harvested and trypsinized to isolate human AECs.The AECs were transfected with AAV-GFP,and the transfection efficiency was detected.RESULTS AND CONCLUSION:Human AECs were successfully primary cultured and passaged in vitro.AAV-GFP-transfected AECs stably and highly expressed GFP,with a transfection efficiency of 58%.

Objective To evaluate the in vitro differentiation of human amniotic epithelial cells (hAECs ) into hepatocyte-like cells. Methods Combined approach of dexamethasone, HGF, IGF and other cytokines were used to induce the differentiation of hAECs into hepatocyte-like cells. The induction lasted 2 weeks. During the induction, the expression of albumin ALB, CYP1A1, CYP1A2, IGFR, c-met and key functional genes related to liver cells as well as transcription factors HNF3, HNF4 and C/EBPa were monitored by RT-PCR. Time dependent changes of the surface marker colony ALB, AFP and CK18 were analyzed by cell flow cytometry. Results After the 2 week induction, the expressions of liver hepatocyte-like cell functional genes such as albumin, CYP1A1, CYP1A2, c-met, and transcription factors such as HNF3, HNF4, C/EBPa and HNF1 were observed. Six days after the induction, hAECs mainly were stained AFP+, and the positive rate was (15.1±2.1)%. While 10 days after the induction, part of the hAECs showed AFP+/ALB+ (6.5±1.4)%; and on 14th day, hAECs only showed ALB+, and the rate was (13.9±2.3)%. ALB+ cell increase indicated a gradual functional maturation from the hAECs to hepatocyte-like cells. Similaritly, the number of CK18+ cells in the whole population was also increased: On 10th day, the rate was (16.1±1.2)%; on 14th day, that was (21.3±4.6)%, which proved the above hypothesis of the trandifferentiation. By extending the induction time, the expression of functional genes increased gradually, and a maturing process of hAECs was detected by cell surface markers. Conclusion The differentiation of hAECs induced in vitro has the characteristics of hepatocyte-like cells.

Objective To establish a methodological study pattern of quantitative analysis of multi-components by single marker ( QAMS) , and examine its feasibility and technical applicability in the quality control of compound preparation of traditional Chinese medicine-Jinhoujian spray. Methods Gas chromatographic method ( GC) was used and naphthalene served as the internal standard. Menthol was used as the reference substance. The relative correlation factors ( RCF) of 1,8-Cineole, camphor and borneol to menthol were calculated and established to carry out QAMS.The accuracy of this method was confirmed by comparison of internal standard method. Results The reproducibility of relative correction factor was perfect. The two methods did not show significant difference in 10 bathes of samples. Conclusion The QAMS method is feasible, credible, and can be used to determine active ingredients in Jinhoujian spray.

Objective To explore the relationship between vicarious traumatization and personality in trauma helpers. Methods Questionnaire about vicarious traumatization and Revised eysenck personality questionnaire short for Chinese(EPQ-RSC) have been carried out on a random sample of 86 trauma helpers in Wenchuan earthquate region from Tangshan. And all the data of the questionnaire scales will be dealt with by the software SPSS11.5. Results ( 1 ) There were significant gender differences on vicarious traumatization of trauma helpers in emotional reaction( famale :20.03 ± 4.92; male: 15.09 ± 3.93 ), behavioral reaction ( famale: 16. 43 ± 4. 49;male: 12.11 ± 2.57 ), cognitional reaction( female: 10.27 ± 3.28; male: 8.29 ± 2.81 ), faith of life ( famale: 14.17± 3.53; male: 11.20 ± 3.37 ), physiological reaction ( female: 21.23 ± 5.31; male: 17.32 ± 4.80) and the total core of vicarious traumatization( famale: 82.70 ± 17.74; male: 64.00 ± 12.49) (P＜0.01). (2) There were significant differences of vicarious traumatization of trauma helpers on professional training and experience of trauma help (P ＜ 0.05 ). ( 3 ) Comparing to helpers of non-vicarious traumatization, the helpers of vicarious traumatization were high in N scale questionnaire (P＜ 0.01 ). Conclusion Vicarious traumatization of trauma helpers are affected by sex, professional training and experience of trauma help. The best choice of trauma helper is steady emotion personality..

Objective To analyze the characteristics of the common first attack of headache in patients with cerebral venous sinus thrombosis (CVST). Methods The clinical data of 51 patients who were diagnosed as CVST with MR venography (MRV)or DSA were collected retrospectively. The patients were divided into either a acute group (≤3 week,n= 32)or a chronic group (>3 weeks, n=19). Results (1)The age of onset of symptoms in these patients was 20 to 40 years,and most of them were females. Of all the first symptoms,headache ranked first,accounting for 84. 3%(43/51 );headache only accounted for 52. 9%(27/51 ),headache with other symptoms (ophthalmic symptoms, hemiplegia,and aphasia,etc. )accounted for 31. 4%(16/51 ),and other symptoms such as epilepsy, paralysis,and ophthalmic symptoms accounted for 15. 7%(8/51). (2)The proportion of headache only as the first symptom in the acute group was higher than that in the chronic group (65. 6% vs. 31. 6%,P<0. 05), and the proportion of chronic headache with other symptoms as the first symptom in the chronic group was higher than that of the acute group (P<0. 05). In addition,the proportion of the first symptom including ophthalmic manifestations in the chronic group was higher than that of the acute group (P <0.01 ). (3)Forty-three patients with headache,dull headache or distensible pain accounted for 72. 1%(31/43), thunderclap headache accounted for 11. 6%(5/43),and other kinds of headache accounted for 16. 3%(6/43),however,there were no significant differences about the types of headache between the two groups (all P>0. 05 ). Conclusion Young patients without previous history of migraine,especially women of childbearing age with sudden onset and progressive worsening headache,and the patients with idiopathic intracranial hypertension,CVST should be considered as an important possibility.

OBJECTIVE: To determine the therapeutic effect of laparoscopic splenectomy, perisoph-agogastric devascularization, and endoscopic variceal ligation (EVL) on patients with portal hypertension. METHODS: We randomly divided 105 patients into 3 groups: 40 had endoscopic band ligation (the ligation group), 35 had splenectomy and perisoph-agogastric devascularization (the laparotomy group), and the other 30 had laparoscopic splenectomy, perisoph-agogastric devascularization and endoscopic variceal ligation (the combination group). Blood samples were analyzed preoperatively and postoperatively on day 1,3,and 7,including alanine aminotransferase(ALT),aspartate aminotransferase(AST),total bilirubin(TBIL),and directed bilirubin(DBIL). The length of stay, blood loss, operation time, anal exhaust time, azygos vein diameter, blood flow velocity and blood flow, recurrence of esophageal varices and rehaemorrhagia were compared. RESULTS: Between the combination group and the laparotomy group, the serum levels of TbIL and Dbil had difference on 1st postoperative day(P<0.05). AST had difference on 7th postoperative day(P<0.05). The length of stay, blood loss, operation time, and anal exhaust time had significant difference(P<0.05). Among the combination group, the laparotomy group and the ligation group, the azygos vein blood flow before and after the treatment, recurrence of esophageal varices and rehaemorrhagia had no difference(P<0.05). CONCLUSION Laparoscopic splenectomy, perisoph-agogastric devascularization and endoscopic variceal ligation have less trauma, lower recurrence rate, fewer complications and rapid recovery, and may reduce the azygous vein blood flow. It can be used safely for portal hypertension.
