The effects of DL-tetrahydropalmatine andsinomemine on the activity of oviduct smooth mus-cle and ovum transport in rabbits are reported inthis paper. The results indicate that the two a-gents apparently inhibit the contractile activity ofoviduct isthmic smooth muscle of rabbit in vitroand decrease the frequency, amplitude, tensionand curve areas of the contraction. The contractileffect induced by noradrenaline is also inhibited re-markbly by them. In addition, DL-THP and Sino.can delay ovum transport in rabbit oviduct after ivHCG 48 h. It is suggested that the inhibition ofactivity of oviduct smooth muscle may be one ofthe important causes of delaying egg transportcaused by the two agents.

Tianjin Medical Journal 2017;45(3):301-305
Objective To investigate the incidence and its related factors of apathy in patients with acute ischemic stroke. Methods A total of 100 consecutive cases of ischemic stroke patients and 50 health controls were recruited in the present study. Apathy was assessed using modified apathy evaluation scale (MAES). According to the MAES score, acute ischemic stroke patients were divided into apathy group (MAES was more than 14 points) and non-apathy group. The differences of general information, clinical data, national institutes of health stroke scale (NIHSS), Montreal cognitive assessment (MoCA), Hamilton depression scale (HAMD), modified rankin scale (mRS) and the lesion location were compared between the two groups. Differences that showed statistical significance (P<0.05) went into the multi-factor analysis. The Logistic regression analysis was used to estimate the influence factors of apathy. Results There were 34 cases of apathy in patient group (34.00%), which was significantly higher than those of control group (3 cases of apathy, 6.00%, P<0.001). The age, incidence of diabetes, NIHSS score, HAMD score, lesions in brain stem and multiple lesions were significantly higher in apathy group than that of non-apathy group, while educational level, MoCA score were significantly lower ( P<0.05). The Logistic regression analysis showed that the higher MoCA score was a protective factor for apathy, while higher NIHSS score, lesions in brain stem and multiple lesions were risk factors for the incidence apathy. Conclusion The cognitive impairment, severity of neurological deficits, brainstem lesions and multiple lesions may be the risk factors of apathy after the occurrence of acute ischemic stroke.

Chinese Health Economics 2013;(11):44-46
Objective: To describe the status of the basic public health service in township health centers, analyze the resource allocation which influences the supply of basic public health service. Methods: The data is based on monitoring project surveys collected by the health statistical information center, Spss13.0 and Excellare applied to make descriptive statistic analysis. Results:Overall, basic public health service has been carried out well in each area, but there are differences among the application rates of different basic public health service items; basic public health service can be effected by the level of basic public health input and the number of public health workers.

Objective To analyze the influence of different types of seizures and nonepileptic events on peripheral white blood cell (WBC)counts. Methods We prospectively collected blood samples from all patients and detered WBC count to evaluate the relation of each type of seizure,duration,frequencies,and ttme lapse between a seizure and collection of blood sample to peripheral WBC count. Results Peripheral WBC count was elevated in about 50% cases after a generalized seizure. The length of a seizures was positively associated, whereas its frequencies and the lapse time was negatively correlated with the increase in WBC counts. Conclusion Peripheral WBC counts increase significantly after a generalized seizure.

Objective:The different subtypes of voltagE-gated sodium channels (VGSCs) are known to correlate with the migration of many malignant cancers. This study was to investigate the significance of functional expression of SCN5A/Nav1.5 in human ovarian cancer and its effects on migration capability of ovarian cancer cells in vitro. Methods: Sodium indicator SBFI and immunofluorescence method were used to detect the distribution of intracellular Na+. Real-time PCR, Western blotting, and immunohistochemistry were used to detect the mRNA and protein expression of SCN5A/Nav1.5. The effect of specific voltagE-gated sodium channels inhibitor tetrodotoxin (TTX) on cell viability was measured by CCK-8 kit. The migration and invasion of ovarian cancer cell lines SKOV-3 were tested by Transwell chamber assay. Results:SCN5A/Nav1.5 were over-expressed in ovarian cancer cell lines SKOV-3 and ovarian cancer specimens at mRNA and protein levels. TTX 30 μmol/L inhibited the intracellular Na+ concentration by (41.51±0.41)%. TTX also suppressed the invasion and migration capacities of SKOV-3 cells by (33.80±1.6)% and (43.60±2.9)%, respectively. The difference was significant (P<0.05). Conclusion:SCN5A/Nav1.5 is involved in the metastasis progression of ovarian cancer in vitro and plays an important role in the initiation and progression of ovarian cancer. It may become a target for ovarian cancer therapy.

Objective To explore the effect of Toll-like receptor 4 (TLR4) on the peripheral blood mononuclear cells(PBMCs) in the development of rheumatoid arthritis (RA) by inducing the differentiation of Th17 cells.Methods Forty two subjects were recruited to the study,including 22 patients with RA and 20 healthy controls (HC).The percentage of circulating Th17 cells were analyzed using flow cytometry.PBMCs were stimulated with LPS for two days.TLR4 mRNA of the PBMCs and the concentration of IL-6 and TNF-α in the supernatants were analyzed with the real-time qPCR and ELISA respectively.Supematants was then used for CD4+ cord blood mononuclear cells (CBMCs) culture,and IL-17 in the supernatants and the expression of IL-17 mRNA in cells were detected by ELISA and real-time qPCR respectively.The statistical analysis was carried out with t-test.Results The TLR4 mRNA expression in the PBMCs and the percentage of circulating Th17 ceils of RA patients were significantly higher than that of the HC group (P<0.01).Stimulated by LPS,the expression of TLR4 mRNA increased 3.5 times in the RA group but decreased 0.11 times in the HC group.LPS also increased cytokines production in both groups,while PBMCs from RA patients produced more IL-6 and TNF-α than the cells from healthy subjects (P<0.01).Compared to the HC group,the IL-17 mRNA expression and IL-17 secretion of CD4+ CBMCs induced by the supematants of RA patients' PBMCs stimulated with LPS was significantly higher(P<0.01 ); but there was no significant difference between the RA group and the HC group without LPS stimulation (P>0.05).Conclusion The expression of TLR4 on PBMCs from patients with RA and its response to LPS stimulation are increased,and it has demonstrated high capability in inducing the differentiation of Th 17 cells.

Reversed phase high performance liquid chromatography with diode array detector was employed for simultaneous determination of six components and specific chromatograms analysis in Liuwei Wuling tablets with gradient elution of acetonitrile and water containing 0.1% phosphoric acid as mobile phase. The results showed that six components containing specnuezhenide, phillyrin, schisandrin, schisantherin A, schizandrin A and schizandrin B were separated well under the analytical condition. The average recoveries ranged from 98.96% to 100.5% with RSD less than 2. 0%. Twenty-five common peaks were selected as the specific chromatograms of Liuwei Wuling tablets with schisantherin A as the reference peak. Similarities calculated by cosine of angle, correlation coefficient and peak area ratio similarity (PAR) were all above 0. 95, indicating a good similarity between the reference and twenty batches of samples. Grubbs test and cluster analysis indicated that the established HPLC fingerprints and HPLC quantitative analysis can be used efficiently in the quality control of Liuwei Wuling tablets.
