Objective: To investigate the effect with its possible mechanisms of zacopride on vasodilatation of isolated coronary arterial rings in experimental rats.
Methods: The tension of vasodilatation of isolated coronary arterial rings of male SD rats was recorded by Powerlab and DMT system. The rats were divided into 4 groups: +Endo (vehicle) group, +Endo (zacopride) group and -Endo (vehicle) group, –Endo (zacopride) group.n=6 in each group. The vasodilatation effects of zacopride on KCl (60 mmol/L) and U46619 (10-6 mol/L) pre-constricted arterial ring were recorded; the effects of different agents on zacopride caused vasodilatation were studied.
Results: In both +Endo (zacopride) and –Endo (zacopride) groups, zacopride showed a dose dependent vasodilatation effect on coronary ring pre-constricted by KCl and U46619. The maximum vasodilatation effect of zacopride in KCl treated+Endo (zacopride) group was (90.15 ± 6.38) %, in U46619 treated-Endo (zacopride) group was (81.67 ± 4.97 ) %; the maximum vasodilatation effect of zacopride in KCl treated-Endo (zacopride) group was (85.48±5.04) %, in U46619 treated–Endo (zacopride) group was (79.65 ± 3.51) %, compared to each corresponding vehicle group, allP<0.05. The inhibitor of IK1 channel, BaCl2 could signiifcantly reduce the vasodilatation effect of zacopride in KCl and U46619 pre-constricted coronary ring,P<0.05. However, the inhibitor of eNOS (L-NAME), the blocker of KCa channel (TEA), blocker of Kv channel (4-AP) and blocker of KATP channel (Glib) had no such signiifcant effects, allP>0.05.
Conclusion: Zacopride had vasodilatation effect on coronary arterial ring which was pre-constricted by KCl and U46619, which might be related to the channel of IK1.

This study was aimed to prepare solid dispersions of Acanthopanax leaves total flavonoids in order to im-prove its bioavailability. PEG4000, PEG6000, F68, PVPK30 were used as carrier materials in the preparation of four different types of solid dispersion to screen the best type of carrier material and evaluate the amount of carrier mate-rial and its influence on the drug dissolution. Rutin was used as reference substance. NaNO2-Al(NO3)3-NaOH was used as the color system, with a UV spectrophotometer measured absorbance at 500 nm. The dissolution characteris-tics of different proportions of solid dispersions were examined in vitro. The results showed that compared with raw material, the in vitro drug release rate with PVPK30 as carrier material in the obtained solid dispersion of the pro-portion of the raw material was significantly improved, and the cumulative release rate was also increased significant-ly. It was concluded that the solid dispersion prepared by solvent method significantly improved in vitro drug release in water.

Objective To evaluate the clinical value of the modified nerve-sparing open antegrade retropubic radical prostatectomy (MNS-ORP).Methods MNS-ORPs were performed in 30 patients with clinically localized prostate cancer.The modified technique included: endopelvic fascia was not incised, the prostate capsule was freed laterally from surrounding fasciae and dorsally;using the method of separating the peripheral fascia of the prostate, the Veil technique was applied to the open operation, that is, the modified Veil perserving nerve technology;pelvic lymph node dissections (9 regions and 5 groups) were extended;bladder neck preservation was completed;deep dorsal vein complex was bunched;jumper intussusception technology was applied for bladder and urethral anastomosis.Functional outcomes of continence and sexual function (IIEF-score) were followed-up.Results Median age of patients was 62 years old, and the level of PSA was 11.9 ng/ml.Median operating time was 150 minutes (75-240 minutes), blood loss was 350 ml (100-1 600 ml), preoperative IIEF-score was 21 scores (15-25 scores).Pathologic stage included pT1 (8 cases), pT2a (15 cases), pT2b (4 cases) and pT3a (3 cases).By Gleason score, there were 2 cases of 5 scores, 7 cases of 6 scores, 20 cases of 7 scores and 1 case of 8 scores.4 cases had positive margins including 2 cases (10.5 ％) of pT2 and 2 cases (67 ％) of pT3.There were no postoperative complications.Mean follow-up was 19 months (6-48 months).At the 1st month, 27 patients (90 ％) got full continence, and at the 3rd month, all of the patients had full continence.At the 3rd month and the 6th month, median IIEF-scores were 13 and 19 scores, respectively with baseline of IIEF-score reaching by 40 ％ (at the 3rd month) and 70 ％ (at the 6th month) of preoperative level.Conclusions MNS-ORP follows rationales of radical prostatectomy and might be considered for selected patients.Preserving all periprostatic fasciae/nerves can recover early continence and maintains potency without affecting outcomes.

Objective:To investigate the expression levels of microRNA-124 (miR-124) and microRNA-494(miR-494) in the serum of elderly patients with Parkinson disease (PD) and its clinical significance.Methods:Ninety PD patients (PD group) who were hospitalized in Zhengzhou Central Hospital Affiliated to Zhengzhou University from March 2018 to April 2020 were selected.At the same time, 100 non-PD elderly people examined in the physical examination center of the same hospital who matched with age and gender of PD patients were selected as the control group.After 12 hours of fasting, 4 ml of venous blood was taken from all subjects.All PD patients were graded by unified Parkinson disease rating scale(UPDRS) from the aspects of mental state, behavior and emotion, quality of life and motor examination, and graded by the Hoehn-Yahr rating scale for Parkinson disease.The expression levels of miR-124 and miR-494 in serum were detected by real-time fluorescent quantitative PCR (qRT-PCR), and the diagnostic values of miR-124 and miR-494 in PD patients were evaluated by ROC curve.Results:Hoehn-Yahr grade of PD patients with UPDRS≤60 points was significantly lower than that of patients with UPDRS >60 points((2.47±0.43) vs (3.42±0.47))( t=9.055, P<0.001), and there was no significant difference in serum miR-124 and miR-494 expression levels((0.72±0.14) vs (0.70±0.12), (1.17±0.19) vs (1.18±0.22)) ( t=0.633, 0.230, P=0.529, 0.819). Compared with that in control group, the expression of miR-124 in PD group was down-regulated ((0.71±0.20) vs (1.05±0.24)), and the expression of miR-494 was up-regulated((1.18±0.26) vs (0.96±0.22)) ( t=10.542, 6.315, P<0.001). The results of ROC showed that the area under curve (AUC) of serum miR-124 and miR-494 in the diagnosis of PD were 0.847 and 0.760 respectively, the cutoff values were 0.901 and 1.126, respectively, the sensitivities were 86.67% and 61.11% respectively, and the specificities were 75.03% and 79.00% respectively. The AUC of the combined diagnosis of PD was 0.898, and the sensitivity and specificity were 85.56% and 85.00% respectively. Conclusions:The expression of miR-124 is low in PD patients, while the expression of miR-494 is high, which suggests that the changes of the two miRNA levels may be related with the occurrence and development of PD.Both of them have a certain diagnostic value for PD, and the value of combined diagnosis is higher.
