OBJECTIVETo explore the mechanism of the eye-acupuncture for treatment of acute cerebral ischemia-reperfusion injury.

METHODSThirty-two healthy SD rats were randomly divided into a normal group, a sham operation group, a model group and an eye-acupuncture group, 8 rats in each group. The rat model of cerebral ischemia-reperfusion was established with thread occlusion method in the model group and the eye-acupuncture group. The eye-acupuncture group was treated by eye-acupuncture at "liver region", "upper energizer area", "lower energizer area" and "kidney region" for 20 min immediately after reperfusion and at 30 min before sampling. No treatment was done in the normal group and the sham operation group, and no thread occlusion was performed in the sham operation group. The Neurologic impairment was scored and the methods of immunohistochemistry staining, western-blotting and real-time fluorescent quantitation polymerase chain reaction (RQ-PCR) were taken to detect the expression of the aquaporin protein 4 (AQP4) and its mRNA in cerebral cortex after reperfusion for 3 hours.

RESULTSThe neurologic impairment score of 1.50 +/- 0.54 in the eye-acupuncture group was significant lower than 2.63 +/- 0.92 in the model group (P < 0.01). The expression of the AQP4 protein by immunohistochemistry and western-blot respectively were 116.33 +/- 10.24 and 0.53 +/- 0.04 in the normal group, 118.97 +/- 12.72 and 0.55 +/- 0.07 in the sham operation group, and 129.30 +/- 18.36 and 0.67 +/- 0.08 in the eye-acupuncture group, with statistical significance compared to 150.88 +/- 15.82 and 0.94 +/- 0.04 in the model group (all P < 0.01), and there were significant differences between the eye-acupuncture group and the normal group (both P < 0.01). The tendency in the expression of AQP4 protein and its mRNA in all the group were almost the same.

CONCLUSIONThe eye-acupuncture therapy can relieve the cerebral ischemia-reperfusion injury and the protective mechanism is related to the downregulation of the cerebral AQP4 expression.

OBJECTIVETo introduce a new procedure of laparoscopic adrenal surgery.

METHODSThirty patients with adrenal disease underwent surgery by a 70 degrees lateral decubital trans-abdominal laparoscopic approach, which wa compared with 30 degrees decubital laparoscopic operation in 26 patients.

RESULTSThe procedure is superior to open laparotomy. There was significant difference in average operative time (77.2 min vs. 215.7 min), blood lost volume (27.0 ml vs. 94.5 ml), and postoperative complications (13.3% vs. 46.0%). Postoperative feeding time and hospitalization time were shortened markedly.

CONCLUSIONSThis modified technique is safe, straightforward, with a good anatomic view during operation. It could be widely adopted for the treatment of benign adrenal disease, especially pheochromocytoma.

Chemical constituents of ethyl acetate extract of Illicium burmanicum were isolated and purified by various chromatographic methods,including Silica gel, Sephadex LH-20, C18 reverse-phased silica gel, Preparative TLC and Preparative HPLC. Their structures were identified by spectral analysis including NMR and MS data. Fourteen compounds were separated from I. burmanicum and their structures were identified as 7S,8R-erythro-4,7,9,9'-tetrahydroxy-3,3'-dimethoxy-8-O-4'-neolignan (1), 7R,8R-threo-4,7, 9,9'-tetrahydroxy-3,3 '-dimethoxy-8-O-4'-neolignan(2) ,polystachyol(3), (-) -massoniresinol(4), angustanoic acid F (5), trans-sobrerol(6), (3S,6R) -6,7-dihydroxy-6,7-dihydrolinalool (7), (3S, 6S) -6,7-dihydroxy-6,7-dihydrolinalool (8), 2,6-dimethoxy-4-allyl-phenol (9), 3,5-dihydroxy4-hydroxy benzaldehyde (10), 3-hydroxy4-methoxybenzaldehyde (11), methyl vanillate (12), shikimic acid ethylester (13) and beta-sitosrerol (14). Except compound 14, the rest thirteen compounds were separated from this plant for the first time.

Objective To analyze the situation of smoking control calls at 12345 citizens′ hotline in Shanghai and investigate the smoking control hotspots concerned by citizens, the handling efficiency and quality of the hotline management, especially after the tobacco control ordinance was amended. Methods Statistical analysis was made on 48 945 smoking control calls, and data model established by natural language processing. Results After amendment of the tobacco control ordinance, there was a great increase in the number of smoking control calls, which reached a peak in 2017, and became 6.7 times that of 2016.Complaint report was the most important part of tobacco control calls, accounting for 76.24% of the total.Work and dining places were the main venue for complaints, while restaurants and offices were with the largest number of calls.The proportion of health departments in all responsible departments was the largest, accounting for 29.71%.Criticism and education were still the main way to deal with the problem, which was far from meeting the demands of citizens in this regard. Conclusion Publicity can mobilize the enthusiasm of the citizens to participate in tobacco control.The working efficiency and quality of responsible departments still needs to be improved.Citizen′s appeal can serve as a reference for future amendments to the law.

OBJECTIVETo investigate the feasibility, effectiveness and practicability of transurethral enucleation plus pneumocystostomy rotary cut (TUE + PCRC) for large benign prostatic hyperplasia (BPH).

METHODSWe performed TUE + PCRC for 26 BPH patients aged 62 - 85 years with the prostate volume of 80 - 165 ml. We conducted transurethral enucleation of the hyperplastic prostate glands and pushed them into the bladder, followed by bladder puncture for pneumo-cystostomy rotary cut.

RESULTSAll the surgical procedures were successfully accomplished, with the mean surgical time of 41 (32 - 54) minutes and intraoperative blood loss < 60 ml in all the cases. Twenty-three of the patients were followed up for 2 - 8 months, which revealed no stricture of the urethra or any other severe complications. Compared with the preoperative baseline, significant improvement was achieved in the IPSS (6.5 +/- 2.2 vs 26.2 +/- 2.4), QOL (1.4 +/- 0.9 vs 4.6 +/- 1.2) and Qmax ([5.8 +/- 1.0 ] vs [19.6 +/- 2.8] ml/s) of the patients after surgery (P < 0.01).

CONCLUSIONTUE + PCRC, with its advantages of short operation time and less severe complications, is a safe and effective approach to the management of large BPH.

Objective To explore the effects of radiofrequency catheter ablation(RFCA)on the blood coaguable states and the clinical value of perioperative plasma D-dimer.Methods The plasma level of D-dimer was assayed by enzyme-linked immunosorbent assay(ELISA)in blood samples of 30 children who were undertaken RFCA.Blood samples were consecutively obtained before cannulating,after electrophysiologic(EP)study,immediately after RFCA,the second day and the seventh day after RFCA.The centrifuged spead was 3 000 r/min,keep it for 10 minutes to obtain the upper plasma,and the crvopreserve.Results The plasma levels of D-dimer was highest at the time point when RFCA was successfully accomplished and restored to preoperative level in the seventh day after RFCA.There were statistically significant difference in the paried values at different time points(Pa

The paper is aimed to investigate the effect of cyclosporine A (CyA) on the pharmacokinetics of ginkgolide B (GB) in rats, and to look for the mechanism of the changes in pharmacokinetic behaviors of GB. GB concentration in plasma, brain homogenate and urine samples of rats was determined by LC-MS. Effects of CyA on plasma levels, brain distributions as well as urinary excretions after intravenous administration of GB were evaluated. CyA co administrated intravenously at 10 mg kg(-1) or 20 mg kg(-1) significantly increased AUC(0-360 min) (P < 0.01) and decreased total CL of GB in rats. While co administrated CYP3A inhibitor itraconazole (ICZ) has no appreciable effect on the pharmacokinetic behavior of GB. CyA increased the brain uptake of GB in a dose-dependent manner. The brain distribution of GB was significantly increased at 5 min by different doses of CyA (P < 0.001), while at 20 and 60 min only high dose of CyA could significantly increase the levels of GB in the brain (P < 0.01 and P < 0.001). Different P-gp inhibitors CyA or verapamil (VER) or digoxin (DGX) decreased the urinary GB excretion, the urinary excretion of GB in 0-8 h were about 34.8% (P < 0.001), 59.4% (P < 0.001) and 79.7% (P < 0.05) of the control, separately. No appreciable effect of ICZ was observed on urinary excretion of GB. Coadministration of P-gp inhibitors CyA could significantly increase the plasma level, accelerate the brain distribution and decrease the urinary excretion of GB.
