Objective To observe the therapeutic efficacy and evaluate the health economics of early rehabilitation intervention applied to patients with cerebral hemorrhage in stroke unit. Methods A total of 131 cerebral hemorrhage patients were randomly assigned to the stroke unit group (n=62) and the control group (n=69). The patients in the stroke unit group received rehabilitation training at a very early stage, while there were no rehabilitation training program and no professional treatment team for patients in the control group. Results of the national institute health stroke scale (NIHSS), activities of daily living (ADL) Barthel index were compared between the two groups. Infection rate, mortality, cost of hospitalization and length of stay were also compared. Results There were better therapeutic effects as revealed by NIHSS (4.3±3.5 vs. 7. 9±5.0, t=-3. 211, P<0.05), ADL Barthel index score (85.9±29.6 vs. 67.1±37.1, t=3.194, P<0.05), lower incidence of infection in lung (8.06% vs. 15.94%, χ~2 =3.901, P<0.05) and in urinary tract (6.45% vs. 11.59%, χ~2 =4. 138, P<0. 05), lower mortality (4.84% vs. 7.25%, χ~2=4. 351, P< 0.05), lower cost of hospitalization[￥ (17506. 90±954.10 ) vs. ￥(21096.49±923.46), t=-20. 786, P<0.01)] and shorter length of stay[(20. 47±7. 03)d vs. (31. 42±8.14)d, t=-8.196, P< 0.01)] in the stroke unit group compared to the control group. Conclusions Early rehabilitation intervention by stroke unit is advantageous to patients with cerebral hemorrhage.

CONCLUSION: The serum containing Compound Rhubarb Mixture can enhance the contractive function of isolated small intestinal smooth muscle of rabbit.

AIM To examine the effect and mechanism of emodin on intestinal movement of constipation model. METHODS The movement of charcoal powder and the absorption of D-xylose into serum were observed. The electrical p otential difference(PD) related to Na + and glucose transport was measured across the wall of rev erted intestinal sacs. RESULTS Emodin 0 1, 0 2 g?kg -1 incr eased markedly the rate of charcoal powder moving and inhibited the absorption of D-xylose into serum. Emodin 0 2, 0 4, 0 8 and 1 6 g?L -1 decreased PD when ther e was glucose. However, emodin had little effect when glucose was free. CONCLUSION Emodin promotes intestinal movement and this effect is related to Na +,K +-ATPase.

Objective:To detect the expression and methylation of TIA1 in breast cancer and to study its correlation with multi-slice spiral CT signs.Methods:50 patients with breast cancer were collected from Feb.2019 to Mar. 2020. The expression levels of TIA1 in breast cancer tissues and in peritumoral tissues were estimated by quantitative real-time polymerase chain reaction. Bioinformatics software MethPrimer was used for predicting TIA1 promotor and confirmed the existence of cPG island. Methylation-specific PCR (MSP) was performed to detect TIA1 DNA promoter methylation. All patients were examined by multi-slice CT. CT images were analyzed through observing the tumor size, shape, calcification area, lymph node metastasis and margin. The correlation between CT signs and TIA1 methylation status was further analyzed.Results:The expression levels of TIA1 in breast cancer tissues were lower than in peritumoral tissues (0.50±0.12, 0.95±0.10, P=0.00) , while TIA1 DNA promoter methylation rate was higher than in peritumoral tissues (64%, 42%, χ2=4.86, P<0.05) .There were no significant differences in TIA1 DNA promoter methylation rate among patients with different tumor shape and micro calcifications. TIA1 DNA promoter methylation rate in patients with mass diameter≥2 cm were significantly higher than those in patients with mass diameter<2 cm (78.57%, 45.45%, P<0.05) , and TIA1 DNA promoter methylation rate in patients with lymph node metastasis was higher than those without lymph node metastasis (79.17%, 50%, P<0.05) . TIA1 DNA promoter methylation rate in patients with burr at edge of mass was higher than those without burr at edge of mass (80.77%, 45.83%, P<0.05) . Conclusion:There is a correlation between CT imaging signs and TIA1 DNA promoter methylation rate in patients with breast cancer, which can provide more reference for the judgment of malignant degree and prognosis of patients with breast cancer.

OBJECTIVE: To study synergistic effect of Vitamin C (VitC) combined with arsenic trioxide (As2 O3)-on human laryngocarcinoma Hep-2 cell line apoptosis. METHOD: Human laryngocarcinoma cell line Hep-2 was cultured in vitro, and incubated with As2 O3 or jointly with VitC. The inhibition ability of Hep-2 cells was determined by methyl thiazolyl tetrazolium (MTT) assay, while the apoptosis was mensurated by the flow cytometry with Annexin-V/PI. RESULT: Compared with the use of As2 O3 separately, the combination of As2 O3 and VitC could increase the inhibition ability and the apoptosis rate of Hep-2 cells markedly (P < 0.05). CONCLUSION Combination of As2 O3 with VitC could markedly increase arsenic trioxide (As2 O3)-induced apoptosis of Hep-2 cells.

Objective:To investigate the expression of circ0008234 and miR-1205 in breast cancer and the oncology characteristics of CT.Methods:40 patients with breast cancer were collected as observational objects from Jan.2018 to Dec.2018 and 40 patients without breast cancer were selected as the control group. The expression levels of circ0008234 and miR-1205 of all patients were estimated by quantitative real-time polymerase chain reaction. Bioinformatics was used for the predictions of circ0008234 target miRNA. A dual-luciferase reporter assay was used to confirm the interaction between circ0008234 and miR-1205. All patients of the observation group were examined by multi-slice CT. CT images were analyzed through observing tumor size, shape, calcification area, lymph node metastasis and margin. The correlation between CT signs and the expression of circ0008234 and miR-1205 was further analyzed.Results:The levels of circ0008234 of observation group were significantly higher than those of the control group (2.23±0.86, 1.07±0.37, P=0.00) , but the expression levels of miR-1205 were lower than the control group (0.76±0.29, 1.04±0.29, P=0.00) . In the observation group, there were no significant differences in the expression of circ0008234 and miR-1205 among patients with different tumor marginal morphology and micro calcifications. However the expression of circ0008234 in patients with regular lump form were significantly higher than those in patients with inregular form (2.52±0.88, 1.91±0.74, P=0.025) , and the expression of miR-1205 were lower than those in patients with inregular form (0.66±0.30, 0.86±0.25, P=0.025) . In the observation group, the expression of circ0008234 in patients with mass diameter≥2 cm were significantly higher than those in patients with mass diameter<2 cm (2.59±0.95, 1.69±0.17, P=0.001) , but the expression of miR-1205 were lower than those in patients with mass diameter<2 cm (0.65±0.21, 0.92±0.33, P=0.003) . In the observation group, the expression of circ0008234 in patients with lymph node metastasis were higher than those without lymph node metastasis (2.55±1.09, 1.94±0.44, P=0.022) , but the expression of miR-1205 in patients with lymph node metastasis were lower than those without lymph node metastasis (0.65±0.26, 0.85±0.30, P=0.027) . miR-1205 was verified as a direct target of circ0008234 by luciferase assay. circ0008234 could negatively regulate the expression of miR-1205. Conclusion:There is a correlation between CT imaging signs and the expression of circ0008234 and miR-1205 in patients with breast cancer, which can provide more reference for the judgment of malignant degree and prognosis of patients with breast cancer.
