The article also introduced the current large-scale TCM clinical trials for acute intracerebral hemorrhage treatment and some systematic reviews on medications in order to provide theoretical evidences for the clinical treatment of acute intrac-erebral hemorrhage.

Objective To investigate the sensitivity difference between CT angiography (CTA)and MR angiography (MRA)in detecting portal hypertension,and explore the diagnostic value of the two methods for portal hypertension.Methods The imaging data of portal hypertension patients who were diagnosed by surgical exploration or vascular intervention in our hospital were collected,the accuracy and sensitivity of CTA and MRA in portal hypertension diagnosis were analyzed.Results A total of 351 portal hypertension patients were included in our study,prehepatic portal hypertension were 89 cases,intrahepatic portal hypertension were 121 cases,posterior portal hypertension were 131 cases.The detective cases about prehepatic portal hypertension,intrahepatic portal hypertension and posterior portal hypertension in MRA group were 85 cases,101 cases and 97 cases,in CTA were 79 cases,120 cases and 128 cases. The portal hypertension detection rate of CTA was 93.16%,there was significant difference with surgical exploration or interventional angiography (P1,3＜0.000 1＜0.05).The portal hypertension detection rate of MRA was 80.63%,there was significant difference with surgical exploration or interventional angiography (P1,2＜0.000 1＜0.05),the differences between MRA and CTA was significant (P2,3＜0.000 1＜0.05). Conclusion The sensitivity of CTA is much higher than MRA,which is a non-invasive examination,and worthy of clinical promotion.

OBJECTIVETo investigate the role of apoptosis stimulating protein 2 of p53 (ASPP2) phosphorylation status in the regulation of ASPP2-p53 apoptotic pathway activity.

METHODSCells were individually transfected with green fluorescent protein (GFP)-encoding vector, constitutively non-phosphorylatable ASPP2 mutant-ASPP2 (Am)-encoding vector, and wild type ASPP2 (Aw)-encoding vector) plasmids, respectively, to make them overexpressing phosphorylated and non-phosphorylated ASPP2 proteins, respectively. Cell apoptosis was induced by oxaliplatin. The apoptosis rate of cells was determined by flow cytometry after staining with FITC-conjugated annexin V and PI. ASPP2 protein level and its phosphorylation status were observed by Western blot. The interaction between ASPP2 and p53 was observed by immunoprecipitation assay.

RESULTSOxaliplatin induced cell apoptosis and caused phosphorylation of ASPP2 at ser92/ser361 in the HCT116 cells. The apoptosis rate of Aw and Am plasmids-transfected cells were (3.8 ± 1.0)% and (3.9 ± 1.2)% respectively, statistically with a non-significant difference (P > 0.05) in comparison with that of the GFP plasmid-transfected cells [(4.0 ± 0.8)%]. After oxaliplatin treatment, the apoptosis rate of Aw plasmid-transfected cells was (46.7 ± 3.9)%, significantly higher than that of the Am and GFP plasmid-transfected cells [(40.1 ± 10.2)% and (37.1 ± 6.9)%, respectively, P < 0.05], however, there was no statistically significant difference (P > 0.05) between Am and GFP plasmid-transfected cells. These results indicate that phosphorylated ASPP2 promoted the oxaliplatin-induced apoptosis of HCT116 cells through a p53-dependent pathway. Phosphorylation status of ASPP2 influenced its binding activity to p53.

CONCLUSIONPhosphorylation status of ASPP2 modulates p53 apoptotic function in oxaliplatin-induced apoptosis of colorectal cancer HCT116 cells.

OBJECTIVETo determine the differential protein and mRNA expressions of mitochondria fusion protein-2 (Mfn2) in hepatic tissues in conditions of cirrhosis and acute on chronic liver failure using rat model systems,and to determine the correlative effects on production of adenosine triphosphate (ATP) and reactive oxygen species (ROS).

METHODSA liver cirrhotic rat model (LC rats) was established by intraperitoneal injection of carbon tetrachloride (CCl4,in vegetable oil),and these mice were subsequently used (10 weeks later) to establish the acute on chronic liver failure rat model (LF rats) by injecting lipopolysaccharide and D-amino-galactose.Control groups (normal controls,NC rats) were established for each model by intraperitoneal injection of vegetable oil only.Protein expression of Mfn2 in liver was quantified by western blotting with fluorescence densitometry and immunofluorescence staining,and mRNA expression was measured by real-time fluorescence quantitative PCR.ROS levels in liver were measured by fluorescence spectrophotometry,and ATP content was measured by bioluminescence assay.Significance of inter-group differences was assessed by one-way ANOVA,and correlations were determined using bivariate statistical modeling.

RESULTSMfn2 protein expression was significantly lower in the liver tissues from modeled rats than that from the control rats (LC:0.051+/-0.004 and LF:0.037+/-0.007 vs.NC:0.254+/-0.008;F=444.98,P less than 0.05).The mRNA expression followed the same trend of lower expression (LC:21.21+/-0.93 and LF:24.35+/-0.85 vs.NC:19.09+/-0.69; F=66.941,P less than 0.05).The ATP content in liver tissues was also significantly lower in the modeled rats (LC:2.07+/-0.05 mol/L and LF:1.81+/-0.11 mol/L vs.NC:3.24+/-0.08 mol/L; F =574.21,P less than 0.05).Lower Mfn2 expression was correlated with lower ATP content (r =0.982) and higher ROS content (r =0.803).

CONCLUSIONReduced Mfn2 expression in liver tissue may cause a decrease in ATP synthesis and increase in ROS generation,thereby disrupting metabolism and increasing oxidative stress in the liver under conditions of cirrhosis and liver failure.

Objective:To investigate the efficacy and adverse reactions of ticagrelor combined with atorvastatin in the treatment of acute cerebral infarction (ACI).Methods:A total of 80 patients with ACI who were diagnosed and treated in Anhui Suixi County Hospital from October 2021 to October 2022 were selected retrospectively and randomly divided into the control group and observation group, each group with 40 cases. The patients in the control group were treated with routine basic treatment and atorvastatin for ACI. The patients in the observation group was treated with ticagrelor on the basis of the control group. The clinical efficacy, neurological function, daily living ability, platelet function (platelet count, platelet inhibition rate), inflammatory factors including high sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6) and adverse reactions of the two groups were compared.Results:The total effective rate of the observation group was higher than that of the control group: 92.50%(37/40) vs. 72.50% (29/40), there was statistical differences ( P<0.05). After treatment, the score of National Institute of Health Stroke Scale of the observation group was lower than that of the control group: (9.37 ± 2.91) points vs. (14.20 ± 3.39) points, and the score of Barthel index scale (BI) was higher than that of the control group: (72.26 ± 13.27) points vs. (58.93 ± 9.43) points, there were statistical differences ( P<0.05). After treatment, the platelet count and platelet adenosine diphosphate (ADP) inhibition rate of the observation group were higher than those of the control group: (284.65 ± 41.58) × 10 9/L vs. (210.46 ± 36.12) × 10 9/L, (79.43 ± 16.42)% vs. (62.40 ± 13.95)%, there were statistical differences ( P<0.05). After treatment, the serum hs-CRP and IL-6 levels of the observation group were lower than those of the control group: (11.64 ± 2.96) mg/L vs. (19.75 ± 4.57) mg/L, (4.26 ± 0.93) ng/L vs. (8.95 ± 1.83) ng/L, there were statistical differences ( P<0.05). There was no significant difference in the incidence of adverse reactions between the two groups after treatment ( P>0.05). Conclusions:Ticagrelor combined with atorvastatin has a better therapeutic effect on ACI, which can effectively improve the neurological deficit and the ability of self-care.

Objective:To analyze the factors influencing prognosis of intrahepatic cholangiocarcinoma (ICC) after surgical resection.Methods:The clinical data of patients diagnosed with ICC and who underwent surgical resection from December 2015 to December 2019 at the Fifth Medical Center of PLA General Hospital were retrospectively analyzed. Of 39 patients who were included in this study, there were 23 males and 16 females, with age of (54.1±7.2) years old. The body mass index, hepatitis B virus infection status, tumor diameter, degree of differentiation, microvascular tumor thrombus, lymph node metastasis, and serum levels of carbohydrate antigen 19-9 (CA19-9) were analyzed as risk factors affecting postoperative recurrence and survival.Results:The median times to recurrence were significantly better in patients with a tumour length <5 cm (11 vs. 5 months), patients without microvascular tumor thrombus (54 vs. 6 months) and patients without lymph node metastasis (8 vs. 5 months) (all P<0.05). The median survival of patients with CA19-9≥100 U/ml was significantly shorter than that of patients with CA19-9<100 U/ml, (9 vs. 27 months, P<0.05). Tumor diameter>5 cm, microvascular tumor thrombus, lymph node metastasis, and CA19-9 ≥100 U/ml are risk factors affecting the recurrence time after ICC resection, CA19-9 ≥100 U/ml is a risk factor affecting survival time after ICC resection. Conclusion:Tumor diameter, microvascular tumor thrombus, lymph node metastasis and CA19-9 can be used to estimate the risk of ICC recurrence, and CA19-9 level can be used to estimate postoperative survival of ICC patients after resection.

Objective: To evaluate the therapeutic effect and security of Buyang Huanwu decoction in treatment of the ischemic stroke recovery. Methods: We retrieved the relevant articles of random and semi- random control trials in treating ischemic stroke recovery using Buyang Huanwu decoction, published in China National Knowledge Infrastructure (CNKI), the Wanfang Data, the Weipu Information Resources System, the Chinese Biomedical Literature Database (CBM), Cochrane Library, PUBMED and MEDLINE from the date of establishment until to March 2018. The quality of studies was evaluated according to the Cochrane Reviewers?? handbook 5.1, and the study was carried out using Cochrane system assessment methods. Statistical analysis was performed with Rev Man 5.3. Results: Altogether 39 studies and 3539 cases of ischemic stroke recovery were enrolled. In terms of clinical efficacy, the difference between Buyang Huanwu Decoction and Western Medicine conventional therapy in the treatment of ischemic stroke was significantly different from that of conventional western medicine therapy [RR =1.26, 95％CI (1.20, 1.31), Z =10.05, P ＜ 0.00001], and the difference between Buyang Huanwu Decoction and other Chinese patent medicines was statistically significant [RR =1.12, 95％CI(1.06, 1.19), Z =3.82, P =0.0001]; neurological deficit NIHSS score [MD =-2.55, 95％CI (-3.10, -2.01), Z =9.20, P ＜ 0.00001]; clinical neurological deficit score (CSS) [MD =-3.85, 95％CI (-5.21, -2.50), Z =5.56, P ＜ 0.00001]; limb motor function score (FMA) [MD =6.10, 95％CI (1.19, 11.01), Z =2.43, P =0.01]; Barthel Index of Daily Living Activity Scale [MD =9.09, 95％CI (6.95, 11.23), Z =8.33, P ＜ 0.00001]; In terms of improving blood rheology index, serum peroxide lipid (LPO), serum superoxide dismutase (SOD) and other biochemical indicators, due to the small number of studies, it may have a certain effect. Most studies did not report adverse reactions. Conclusion: Based on the existing clinical evidence, combination of Buyang Huanwu decoction and western medicine has higher clinical efficacy than western medicine alone for the ischemic stroke recovery. Due to the limited methodological quality of the included studies, more high- quality RCTs with large scale are needed to increase the strength of the above evidence.

Objective: To investigate the effect of Δ40p53, an alternative spliced isoform of p53 lacking the N-ter minus, on the pro-apoptotic function of p53. Methods: The wild-type p53 was ectopically expressed in HCT116-p53^-/- (endogenous Δ40p53 expression), HCT116-p53^{+ /+} (wild-type p53) and H1299 (p53-null) cells by adenoviral delivery, while Δ40p53 plasmid were transfected into these cells to overexpress Δ40p53. The levels of Δ40p53 and p53 mRNA were detected by reverse transcription-polymerase chain reaction (RT-PCR) and quantitative PCR. The expression of related proteins was deter mined by Western blotting. The interaction of p53 and Δ40p53 was observed by co-immunoprecipitation assay. Calcein-AM/propidium iodide (PI) staining and flow cytometry were used to detect the apoptotic rate of tested cells in each group. Results: HCT116-p53^-/- cells expressed endogenous Δ40p53 isoform. Neither transcription nor protein expression of wild-type p53 was interfered by the increased expression of Δ40p53. Full length p53 and Δ40p53 could bind to each other. Calcein-AM/PI staining showed that the apoptotic rates of H1299-Control, HCT116-p53^-/- -Control, H1299+ p53, HCT116-p53^-/-+ p53, H1299+ oxaliplatin (Oxa), HCT116-p53^-/-+ Oxa, H1299+ p53+ Oxa and HCT116-p53^-/-+ p53+ Oxa groups were (2.50±0.47)%, (2.40±0.32)%, (5.20±0.58)%, (4.10±0.18)%, (22.40±1.73)%, (19.30±1.11)%, (29.90±1.15)% and (39.30±2.26)%, respectively. It was statistically significant between H1299+ p53+ Oxa and HCT116-p53^-/-+ p53+ Oxa groups (t=3.721, P=0.0205). Moreover, the apoptotic rates of H1299-Control, H1299+ Δ40p53, H1299+ p53, H1299+ p53+ Δ40p53, H1299+ Oxa, H1299+ Δ40p53+ Oxa, H1299+ p53+ Oxa and H1299+ p53+ Δ40p53+ Oxa groups were (2.60±0.35)%, (2.20±0.17)%, (4.80±0.49)%, (4.90±1.10)%, (20.30±1.10)%, (19.60±1.45)%, (27.90±1.39)%, (35.20±1.43)%, respectively. Furthermore, flow cytometry assay showed that the apoptotic rates of above cells were (2.70±0.32)%, (2.20±0.24)%, (4.60±0.48)%, (3.90±0.67)%, (19.30±1.11)%, (17.70±0.66)%, (28.30±2.76)% and (37.50±1.51)%, respectively. H1299+ p53+ Δ40p53+ Oxa cells showed higher cell apoptosis than H1299+ p53+ Oxa cells (t=2.930, P=0.042). Conclusion Δ40p53 isoform can bind to full-length p53, and enhance its pro-apoptotic function in tumor cells.
