Objective To observe the clinical effect of self-made Jingxuan decoction in treating vertebroarterial vertigo of cervical vertebra disease. Methods Sixty five patients were randomly recurited into a control group (30 cases) and a treatment group (35 cases). The contol group received safflor yellow and sodium chloride injection, deproteinised calf blood serum injection, flunarizini, and metroclopramidum; While the treatment group received self-made Jingxuan decoction besides the treatments in the control group. 7 days constituted a course of treatment. The curative effects were assessed after two courses of treatment. Results The effective rate was 94.29% in the treatment group and 76.67% in the control group, showing significant difference (P<0.05). Conclusion Self-made Jingxuan decoction is an effective drug for vertebroarterial vertebroarterial vertigo of cervical vertebra disease.

Objective To analyze the efficacy and debase the toxicity of radiotherapy combined with composite Kushen injection in treatment of esophageal carcinoma patients. Methods A total of 126 cases of esophageal cancer were treated by radiotherapy were analysed. All patients were treated with the continuative hyperfractionated radiotherapy. The total dose was 66 ~ 74 Gy/5 ~ 7 wk, 2.2 ~ 2.4 Gy/d of esophageal carcinoma patients. Two groups were given respectively delivered with the same radioactive dosages and methods.But the synthetic group was treated by radiotherapy with composite Kushen injection. composite Kushen injection was given at the dosage of 20 ml with 500 ml of saline infusion for 20 consecutive days. Results X-ray grades of esophageal cancer after radiotherapy. The grade I of X-ray manifestation after radiotherapy for patients in synthetic group was superior to that patient in the radiotherapy alone group. (60.4 % vs 41 %; ?2 =4.57, P

We has studied the feasibility of preventing protein from denature during covalent immobilization by "conformation memory", which was achieved by freeze-drying under enzyme active conformation and cross-linked with carrier under micro-aqueous media (MAM). Horseradish peroxidase (HRP) and chitosan beads have been used as the model enzyme and carrier. The MAM consisted of 99% dioxane and 1% water. We compared the immobilized HRP under MAM with that under traditional aqueous solvent, found that the optimum temperature of both was raised to 60 degrees C, and the optimum pH was 6.5. However, the MAM-immobilized HRP had shown less activity loss during usage and six times higher activity than that immobilized under aqueous solvent. After 30 min incubation at 70 degrees C, the MAM-immobilized HRP remained 75.42% activity while the aqueous-media-immobilized enzyme only 15.4%. The MAM-immobilized HRP has shown a better operation stability with 77.69% residue activity after 5 times of repeat operation while the aqueous-media-immobilized enzyme only 16.67%. In addition, the MAM-immobilized HRP had also shown more advantages when used in phenol removal. We constructed enzyme electrodes (CS-HRP-SWCNTs/Au) to further display the different properties of the two immobilized HRP. MAM-immobilized HRP-electrode has shown two times stronger response signal to H2O2 than that immobilized under aqueous media, which indicated a better enzyme activity of MAM-immobilized HRP. Our research demonstrated that the conformation memory, to some extent, did contribute to preventing protein from denaturing when use HRP as a model, and it is feasible to immobilize enzyme by covalent cross-linking method under micro-aqueous media.

OBJECTIVEPsoriasis is an autoimmune-related chronic inflammatory skin disease strongly associated with the dysfunction of Th17 cells. Retinoic acid-related orphan nuclear receptor γt (RORγt) plays a critical role in the differentiation and maturation of Th17 cells and in cell-derived immunologic derangement. We conducted this study to investigate potential mechanism by which the derivative of digoxin selectively antagonizes RORγt transcriptional activity.

METHODUsing molecular docking in combination with molecular electrostatic potential (MEP), we detected the interaction between the derivative of digoxin (Dhd) and ROR transcription factor (RORα,RORβ and RORγt), and the results were further confirmed by bioluminescent assay.

RESULTMolecular docking demonstrated that Dhd could exclusively inhibit the conformation of RORγt; bioluminescent assay further indicated that RORγt was selectively antagonized by Dhd in a dose- and time-dependent manner.

CONCLUSIONDhd can selectively suppress RORγt transcriptional activity.

After cardiectomy , left atrial-atrial anastomosis was performed initially between donor ' s left-upper pulmonary vein orifices and recipient's left-lower pulmonary vein orifices .Apex was orientated at a 90 degrees' clockwise to right . Then aorta ,inferior and superior vena cava and last pulmonary artery were anastomosed continuously . The prosthetic conduits were also used owing to a lack of tissue . Results All operations were successful . The cold ischemic time was (130-375 ) (251 .00 ± 122 .53) min ,cardiopulmonary bypass time (127-212 )(179 .67 ± 55 .72 ) min and aortic clamp time (38-105 ) (65 .33 ± 35 .166) min .

Background::Arterial stiffening increases with age and blood pressure and is associated with cardiovascular disease (CVD), but the relationship between blood pressure lowering and arterial stiffening is still uncertain, especially in older people. This study aimed to evaluate the effect of intensive blood pressure treatment on the progression of arterial stiffness and risk of CVD in older patients with hypertension.Methods::The Strategy of Blood Pressure Intervention in the Elderly Hypertensive Patients (STEP) trial was a multicenter, randomized, controlled trial performed at 42 clinical centers throughout China, and 8511 patients aged 60–80 years with essential hypertension were enrolled and randomly assigned to systolic blood pressure (SBP) target of 110 mmHg to <130 mmHg (intensive treatment) or 130 mmHg to <150 mmHg (standard treatment). Patients underwent repeated examinations of the brachial-ankle pulse wave velocity (baPWV) and ankle-brachial index (ABI) at baseline, and the arterial stiffness was evaluated at the 3-year follow-up. A total of 5339 patients who had twice repeated measurements were included in this study. Changes in arterial stiffness between the intensive and standard treatment groups were analyzed using a multivariate linear regression model. The Cox proportional hazard regression model was used to evaluate the effect of intensive treatment on primary CVD outcomes.Results::The changes in baPWV were 61.5 cm/s (95% confidence interval [CI]: 49.8–73.2 cm/s) in the intensive treatment group and 98.4 cm/s (95% CI: 86.7–110.1 cm/s) in the standard treatment group ( P <0.001). Intensive treatment significantly delayed the progression of arterial stiffness, with an annual change of 23.1 cm·s –1·year –1vs. 36.7 cm·s –1·year -1 of baPWV in the intensive and standard treatment groups, respectively. During a median follow-up period of 3.36 years, primary CVD outcomes occurred in 77 (2.9%) patients in the intensive treatment group compared with 93 (3.5%) in the standard treatment group. Intensive treatment resulted in a significantly lower CVD risk in patients aged 70–80 years or with SBP <140 mmHg. Conclusion::Intensive blood pressure control with an SBP target of 110 mmHg to <130 mmHg could delay the progression of arterial stiffness and reduce the risk of CVD in older patients with hypertension.Clinical trial registration::http://www.clinicaltrials.gov; No. NCT03015311.
