Objective To investigate the effect of berberine on the radiosensitivity of cervical cancer cells.Methods 5,10,15,20 μmol/L of berberine were used to treat cervical cancer cell lines of Siha,HeLa,Caski.DMSO was applied as control of drug treatment.Cell proliferation was detected by the CCK-8 method,and then the half inhibitory concentration of berberine was calculated.Cell apoptosis and cell cycle distribution were detected by flow cytometry.Protein expressions of Cleaved Caspase-3,Cyclin B1,CDK1,STAT3 and p-STAT3 were detected by Western blot.Cervical cancer cells of Siha were treated by berberine with a half inhibitory concentration for 24 h and then irradiated with 0,2,4,6,8 Gy of X-rays.Cell clone assay was used to detect cell survival.Results Berberine could inhibit the growth of cervical cancer cells with a half inhibition concentration of(16.84 ± 3.52),(23.54 ± 8.67),(21.86 ± 6.35)μmol/L for Siha,Caski,and HeLa cells,respectively.The berberine at 17 μmol/L could induce apoptosis (t =56.847,P ＜ 0.01) and G2/M phase arrest (t =47.251,P ＜ 0.01) in Siha cells,which also inhibited the expressions of Cyclin B1,CDK1 and p-STAT3 and promoted the expression of cleaved Caspase-3,but did not influence the expression of STAT3 in cervical cancer cells.Treatment of cells with 17 μmol/L berberine increased the radiosensitivity of cervical cancer cells with a sensitivity enhancement ratio of 1.55.Conclusions Berberine can inhibit cell proliferation,promote apoptosis,block cell cycle,and increase radiosensitivity of cervical cancer cells.

OBJECTIVESTo explore the significance of noninvasive central blood pressure detection in blood pressure management and vessel function assessment of hypertension.

METHODSA total of 348 subjects were recruited in the study and A-pulse CASP software were derived to measure the parameters of CASP and vessel function. The recruited subjects were divided into different groups for analysis according to age and disease.

RESULTS(1) CASP in hypertension group were both higher than those in normal group, while RAI and PRT lower. (2) Hypertensive patients of which brachial blood pressure were controlled have lower CASP and RAI than those above the level. (3) Hypertensive patients whose brachial blood pressure were controlled have significantly higher CASP than normal subjects.

CONCLUSIONSCentral blood pressure is more reflective of actural blood pressure and vessel function. Enhanced control of CASP in hypertensive patients contributes to improving vessel compliance.

Objective To study the efficacy of entacapone for motor fluctuations in Parkinson's disease. Methods Pubmed, Embase, Cochrane Database were searched for randomized controlled trial studies (RCTs) on entacapone compared to placebo in the treatment of Parkinson' s disease with motor fluctuations. Data were extracted and evaluated by two reviewers independently with designed extractian form. Revman 4. 2. 10 software was used for data analysis. Results Ten RCTs involving 2212 patients were included. The Results showed that entaeapone tends to increase "on" time, decrease "off" time and daily levodopa dosage (WMD=-1.41,95% CI -2. 09- -0.72) and improve "on" time motor symptoms and the quality of life. But it might increase the rate of dyskinesia (OR=2.00, 95% CI 1.55-2.58).Conclusion The systematic review indicates that entaeapone might be an effective agent for parkinsonian patients with motor fluctuations and more high quality RCTs with the same effect measures are required.

Objective To systemically evaluate the therapeutic effect of pramipexole in treating Parkinson's disease. Methods Pubmed, Embase, Cochrane Database were used to search for randomized control trials (RCTs) on Parkinson's disease treated with pramipexole. Meticulous data wre extracted and meta-analysis was performed according to a preset protocol. Results Ten RCTs involving 1738 patients were included. The results of meta-analysis showed that pramipexole decreased the total scores of unified Parkinson's disease rating scale [UPDRS, WMD=-10.01,95%CI (-12.76,-7.26)],UPDRS part [WMD=-2.44,95%CI(-2.93,-1.95)],and UPDRS partⅢ[WMD=-6.61,95%CI(-8.38,-4.84)]. Pramipexole also reduced the score of UPDRS part Ⅳ[WMD=-0.73,95%CI(-1.16,-0.30)] in advanced patients(P＜0.05＝.Three studies referred to the effect of pramipexole in treating parkinsonian tremor. However there was a clinical heterogeneity among the studies, and two of them revealed a significant difference. Conclusions Pramipexole might improve motor symptoms and the quality of life in advanced patients, as well as improve tremor, which needs more RCTs to be confirmed.

Objective To assess the prevalance and distribution of pain in Parkinson' s disease (PD) patients, and to describe the relationship between pain and development of disease and its impact on the quality of life. Methods 113 PD patients were assessed with Visual Analog Scale (VAS), Brief Pain Inventory (BPI), Unified Parkinson' s Disease Rating Scale (UPDRS), Hoehn-Yahr Scale (H-Y), Hamilton Anxiety and Depression Scale (HRSD, HAMA) and Pittsburgh Sleep Quality Index (PSQI). Patients were divided into no pain group, PD-pain group and non-PD-pain group. PD-pain group was divided into PD-pain direct group and PD-pain indirect group. And statistical analysis was performed for each group. Results The incidence of PD-pain was 42. 5% (48/113). And compared with no pain group, PD-pain group had earlier age at onset of disease, longer duration, higher HAMA, HRSD, UPDRS and H-Y score, higher daily L-dopa dose, with statistical significance. Compared with non-PD pain group, the differences in the onset of age (57.4±9.6 vs 65.9±8.7, t= -2.596, P =0.012), HRSD(12. 9±7.9 vs 8.7±3.7, t =2.605, P=0.014) and VAS (61.6±25.9 vs 38.0 ± 30. 1, U = -2.290, P =0.022) were also statistically significant. BPI was different between PD-pain direct group and PD-pain indirect group except normal work and relations with other people. Conclusion Pain is frequent in Parkinsonian population. Most pain was chronic and related to PD (PD-pain). These patients always have earlier onset age and poorer quality of life.

Objective To investigate the effect of persistent hypoglycemia on the cerebral oxidative stress and matrix metalloproteinase-2 (MMP-2) activity of newborn rats and to explore the potential mechanism of hypoglycemia-induced brain injury of newborn.MethodsSeven-day-old rats were injected insulin subcutaneously to induce persistent hypoglycemia.Cerebral cortex,hippocampus and thalamus were collected after 36 hours' observation and stored in -80 ℃.Glutathione (GSH)and glutathione disulfide (GSSG) were detected by commercial kit and GSSG/GSH was calculated.MMP-2 activity was detected by gelatin zymography. The data were analyzed by t test,one or two-wayanalysis of variance and Pearson correlation analysis.Six rats were set as the normal glucose group. ResultsThirty-six hours after induction of hypoglycemia, the cerebral GSSG and GSSG/GSH of hypoglycemic pups elevated about 1.5 times higher than those of control group [GSSG:(15.89 ± 5.46) vs (6.15 ± 3.42) mg/g protein,t =3.704,P =0.004; GSSG/GSH:(5.58± 1.79) ％ vs (2.79±1.76) ％,t =2.712,P=0.022].The GSSG and GSSG/GSH in thalamus of hypoglycemia were significantly higher than those of control [GSSG:(15.93 ± 5.75) mg/g protein vs (5.03±5.14)mg/g protein,P＜0.05; GSSG/GSH:(6.50±3.25) ％ vs (2.41±3.12) ％,P＜0.05],whereas there were no significant differences in the cortex ard hippocampus.The total MMP-2 activity of hypoglycemic animals (2.22±0.59) was significantly higher than that of control (1.21± 0.17)(t=4.064,P=0.002),and significant differences were found between the two groups in cortex (2.14 ± 0.5 vs 1.17± 0.27),hippocampus (2.31± 0.72 vs 1.22 ± 0.37) and thalamus (2.22±0.68 vs 1.24±0.18) with all P＜0.01].The activity of MMP-2 was positively related to GSSG (r=0.575,P=0.0002) and GSSG/GSH (r=0.484,P=0.0003).ConclusionsOxidative stress might play an important role in the persistent hypoglycemia induced brain injury of 7-day-old rat pups and thalamus might be most vulnerable to hypoglycemia.Hypoglycemia might also elevate MMP-2 activity which is positively related to GSSG level and GSSG/GSH of the brain.

Uracil (I) (2,4-Diketo-pyrimidine) was isolated from the radix aconiti collected from Jiangyou region of Sichuan Province.The chemical structure of this principle was determined by elemental analysis,IR,UV,MS,'H and 13C-NMR spectral data. The experiments were made to study the effect of uracil (I) on the cardiac contractile force and beating rate of the isolated toad hearts in comparison with uracil (II) (artificial synthesis). The results indicated that the 5?mol/L of uracil (I) and uracil (II) both had the effect of increasing the amplitude of myocardial contraction (P0.05) at 3 and 5 min. When the concentration was increased to 10 and 20?mol/L, the amplitudes of myocardial contraction were more incremental and 3 min later,the estimated value of uracil (I) and uracil (II) to increase the amplitude of myocardial contraction by 50% approached to 4.17 and 4.68, respectively. As described above, uracil (I) is a new cardiotonic in Jiangyou Fuzi.
