Objective To investigate the effect of intravenous thrombolysis with different doses of alteplase on neurological function in patients with acute ischemic stroke.Methods 120 patients with acute ischemic stroke were selected as the research subjects.According to the admission time,the patients were divided into the observation group and the control group,60 patients in each group.The observation group was treated with low dose alteplase(0.6mg/kg),the control group was given standard dose(0.9mg/kg).The clinical curative effect,incidence rate of adverse event,NIHSS score and mRS score before and after treatment were observed and recorded in the two groups.Results Before treatment,there was no significant difference between the two groups in NIHSS score(t=0.288 0,P=0.773 9).After treatment for 3 days,the NIHSS score of the control group decreased compared with before treatment,and was lower than that of the observation group at the same period,there was significant difference between the two groups(t=0.778 5,P=0.000 0).Before treatment,the mRS score between the two groups had no siginificant difference(t=0.801 0,P=0.424 7).After treatment for 90 days,the mRS score of the two groups decreased,the difference was statistically significant(t=6.811 5,P=0.000 0).After treatment,1 patient with cerebral hemorrhage was observed in the observation group,while 3 cases in the control group,the difference between the two groups was not statistically significant(χ2=1.034 5,P=0.309 1).The mortality of the observation group was 11.47％,which of the control group was 1.67％,there was significant difference between the two groups(χ2=4.821 4,P=0.028 1).The good prognosis rate of the observation group was 45％,which of the control group was 68.33％,the difference was significant between the two groups (χ2=6.651 6,P=0.009 9).Conclusion Standard dose of alteplase in the treatment of acute ischemic stroke has better efficacy than low-dose alteplase,it has improved conditions of neurological deficits in patients,better recovery of neurological function,the prognosis is good,it can be widely recommended.

Objective To compare the efficacy and safety of tenofovir disoproxil fumarate ( TDF) and entecavir(ETV) in the treatment of chronic hepatitis B(CHB) with positive hepatitis B E antigen(HBeAg). Methods A total of 104 cases with newly diagnosed HBeAg positive CHB were selected and randomly divided into TDF group and ETV group,with 52 cases in each group. The TDF group was given 300mg/d TDF,and the ETV group was given 0. 5mg/d ETV. All the patients were continuously treated for 12 months. The serum HBV DNA, HBeAg and ALT levels before and after treatment were compared between the two groups. Results Before treatment,there were no statistically significant differences in serum HBV DNA,HBeAg and ALT levels between the two groups ( t=0. 12, 1. 51,1. 62,all P＞0. 05). The serum HBV DNA,HBeAg and ALT levels in the two groups were decreased after treatment,and the decrease of serum HBV DNA level in the TDF group was more significant than that in the ETV group,the difference was statistically significant(t =3. 54,P ＜0. 05),but there were no statistically significant differences in serum HBeAg and ALT levels between the two groups(t=0. 04,0. 79,all P＞0. 05). The total effective rate of the TDF group was 92. 31% (48/52),which was significantly higher than 76. 92% (40/52) in the ETV group (χ2=4. 73,P＜0. 05). During treatment,the incidence rate of adverse reaction of the TDF group was 7. 69% (4/52),which was lower than 11. 54% (6/52) of the ETV group,but the difference was not statistically significant (χ2=0. 44,P＞0. 05). Conclusion TDF has better clinical effect in treating newly diagnosed HBeAg positive CHB than ETV due to TDF can inhibit HBV DNA replication significantly,but the safety of TDF and ETV is similar.

BACKGROUND: Nowadays, biological tissue engineering is a growing field of research. Biocompatibility is a key indicator for measuring tissue engineering biomaterials, which is of great significance for the replacement and repair of damaged tissues. METHODS: In this study, using gelatin, carboxymethyl chitosan, and sodium alginate, a tissue engineering material scaffold that can carry cells was successfully prepared. The material was characterized by Fourier transforms infrared spectroscopy. In addition, the prepared scaffolds have physicochemical properties, such as swelling ratio, biodegradability.we observed the biocompatibility of the hydrogel to different adult stem cells (BMSCs and ADSCs) in vivo and in vitro. Adult stem cells were planted on gelatin-carboxymethyl chitosan-sodium alginate (Gel/SA/CMCS) hydrogels for 7 days in vitro, and the survival of stem cells in vitro was observed by live/died staining. Gel/SA/CMCS hydrogels loaded with stem cells were subcutaneously transplanted into nude mice for 14 days of in vivo culture observation. The survival of adult stem cells was observed by staining for stem cell surface markers (CD29, CD90) and Ki67. RESULTS: The scaffolds had a microporous structure with an appropriate pore size (about 80 lm). Live/died staining showed that adult stem cells could stably survive in Gel/SA/CMCS hydrogels for at least 7 days. After 14 days of culture in nude mice, Ki67 staining showed that the stem cells supported by Gel/SA/CMCS hydrogel still had high proliferation activity. CONCLUSION Gel/SA/CMCSs hydrogel has a stable interpenetrating porous structure, suitable swelling performance and degradation rate, can promote and support the survival of adult stem cells in vivo and in vitro, and has good biocompatibility. Therefore, Gel/SA/CMCS hydrogel is a strong candidate for biological tissue engineering materials.

Objective:To explore the expression of abnormal spindle-like microcephaly-associated (ASPM) in liver cancer tissues and clarify its prognostic relationship with clinicopathological features of liver cancer after liver transplantation.Methods:Immunohistochemistry was employed for detecting the expression of ASPM in 72 liver cancer tissues and 36 adjacent tissues of liver cancer liver transplant recipients fulfilling the Hangzhou criterion. In conjunctions with clinicopathological data, the correlation between the expression level of ASPM in liver cancer tissues and the clinicopathological characteristics and the post-transplantation prognosis for liver cancer were statistically analyzed.Results:During a median follow-up period of 29 months, 20 patients relapsed and 8 died after transplantation. Immunohistochemical results indicated that the high-expression rates of ASPM were 58.3% and 25.0% in liver cancer and adjacent tissues ( P=0.001). The difference was statistically significant. The high-expression rate of ASPM was significantly higher in liver cancer tissues than that in adjacent tissues. The expression level of ASPM was not correlated with gender, age, smoking/alcoholic history, hepatitis history, preoperative level of alpha-fetoprotein (AFP), tumor size, tumor load or vascular tumor thrombus ( P>0.05). And the postoperative high-expression rates of ASPM were 51.0% and 76.2% in pathological differentiation type Ⅰ-Ⅱ and Ⅲ-Ⅳ groups ( P=0.049). The difference was statistically significant. The wrose pathological differentiation type of liver cancer, the higher expression level of ASPM in liver cancer tissue. In liver cancer tissues, the overall 1/3/5-year survival rates of ASPM high/low-expression group were 97.6%, 80.6%, 80.6% and 93.3%, 89.7% and 89.7% respectively ( P>0.05). There was no statistical significance. And 1/3/5-year long-term disease-free survival rates were 78.6%, 55.5%, 55.5% and 86.3%, 86.3% and 86.3% respectively ( P=0.036). The difference was statistically significant. The disease-free survival rate was lower in ASPM high-expression group and post-transplantation prognosis was worse. Conclusions:The expression of ASPM is significantly higher in liver cancer tissues than that in adjacent tissues. And the expression level of ASPM in liver cancer tissues is correlated with pathological differentiation types of liver cancer and has an impact on tumor-free survival of patients after liver transplantation for liver cancer.

Primary central nervous system lymphoma (PCNSL) is an uncommon non-Hodgkin's lymphoma with poor prognosis. This study aimed to depict the genetic landscape of Chinese PCNSLs. Whole-genome sequencing was performed on 68 newly diagnosed Chinese PCNSL samples, whose genomic characteristics and clinicopathologic features were also analyzed. Structural variations were identified in all patients with a mean of 349, which did not significantly influence prognosis. Copy loss occurred in all samples, while gains were detected in 77.9% of the samples. The high level of copy number variations was significantly associated with poor progression-free survival (PFS) and overall survival (OS). A total of 263 genes mutated in coding regions were identified, including 6 newly discovered genes (ROBO2, KMT2C, CXCR4, MYOM2, BCLAF1, and NRXN3) detected in ⩾ 10% of the cases. CD79B mutation was significantly associated with lower PFS, TMSB4X mutation and high expression of TMSB4X protein was associated with lower OS. A prognostic risk scoring system was also established for PCNSL, which included Karnofsky performance status and six mutated genes (BRD4, EBF1, BTG1, CCND3, STAG2, and TMSB4X). Collectively, this study comprehensively reveals the genomic landscape of newly diagnosed Chinese PCNSLs, thereby enriching the present understanding of the genetic mechanisms of PCNSL.
