Objective To observe the effect of saccharomyces boulardii combined with chiropractics in asphyxial newborn with feeding intolerance. Methods One hundred and twenty asphyxial newborn with feeding intolerance were allocated into observation group (68 patients) and control group (52 patients) by random digits table. The newborn in control group accepted trace feeding and parenteral nutrition treatment, and the newborn in observation group accepted additional oral saccharomyces boulardii and chiropractic therapy on the base of control group. The time of reaching to full enteral feeding, the time of restoring to birth weight, the incidence of hyperbilirubinemia and the total efficiency of treatment were observed. Results The time of reaching to full enteral feeding, the time of restoring to birth weight in either mild asphyxial newborn or severe asphxial newborn in observation group were significantly lower than those in control group (P<0.01 or<0.05). The incidence of hyperbilirubinemia in mild asphyxial newborn or severe asphxial newborn in observation group was 16.7%(8/48) and 5/20, in control group was 36.8%(14/38) and 9/14, and there were significant differences (P<0.05). The total efficiency of treatment in observation group was significantly higher than that in control group:91.2%(62/68) vs. 69.2%(36/52), P<0.05. Conclusions Saccharomyces boulardii combined with chiropractics in asphyxial newborn with feeding intolerance can reduce the time of reaching to full enteral feeding and the time of restoring to birth weight. It can decrease the incidence of hyperbilirubinemia, and the treatment effect is obvious.

Objective Using the effect of microneedle array to investigate the feature and rule of transdermal drug delivery of sinomenine hydrogel patch.Methods The microneedles with different length and sinomenine hydrogel patch were prepared;The isolated rat skin was pretreated by different needle-shapes of microneedle array and different timepoints with the same needle-shape,and then sticked the sinomenine patch.The permeation rates of sinomenine were studied using a Franz diffusion cell and compared with passive diffusion of the rat skin untreated.Sinomenine content was measured by HPLC.Results The permeation rates of sinomenine via the skin pretreated with 100 and 200 ?m microneedles were 40.7 and 52.4 times to those of the untreated.The permeation rates of sinomenine via the skin pretreated 7 min with 200 ?m microneedles is 142.0 times to those of the untreated.When skins were pretreated using 200 ?m microneedles with different force, the drug permeation rates were increased with the force increasing.When the force exceeded 5 N,the drug permeation rates were equilibrium.Conclusion When transdermal drug delivery by using microneedle array-hydrogel patch,the permeation rates increase significantly.The needle-shape,skin pretreating time,and force of the microneedles play the important roles in the transdermal drug delivery.

Objective:To explore the regulatory effect of miR-873-5p micro-RNA targeting voltage-dependent anion channel protein 1 (VDAC1) in neurons and its mechanism.Methods:Murine nerve cells were randomly divided in vitro into a control group, a model group, a mimetic negative carrier (miR-con) group and an miR-873-5p group. The epileptiform hippocampal nerve cell model was induced in all of the cells except those in the control group using magnesium-free medium. The control group was normally cultured, while the miR-con and miR-873-5p groups were transfected with miR control and miR-873-5p RNA respectively. Real-time fluorescent quantitative polymerase chain reactions were used to detect the expression of miR-873-5p and VDAC1 mRNA. Western blotting was employed to detect VDAC1, B-cell lymphoma/leukemia-2 protein (Bcl-2), Bcl-2 associated X protein (Bax) and cleared caspase-3 in the neurons. The levels of reactive oxygen species (ROS), malondialdehyde (MDA) and glutathione (GSH) were measured using the DCFH-DA fluorescent probe, the thiobarbituric acid method and enzyme-linked immunosorbent assay respectively. Any apoptosis was detected using flow cytometry, while the targeting of miR-873-5p on VDAC1 was verified using the double fluorescence zymase reporter gene method.Results:Compared with the control group, a significant decrease in the average expression of miR-873-5p, Bcl-2 and in GSH and MDA levels was observed in the model group, but there was a significant increase in the average level of VDAC1, Bax, cleaved caspase-3 and ROS and in the rate of apoptosis. Compared with the miR-con group, a significant decrease in the average expression of Bax, cleaved caspase-3, ROS and in the apoptosis rate was observed in the miR-873-5p group, but there was a significant increase in the average level of Bcl-2, GSH and MDA. Moreover, it was verified that miR-873-5p reduced the expression of VDAC1.Conclusion:miR-873-5p protects damaged neurons by inhibiting their apoptosis through negatively regulating the target gene VDAC1 and the oxidative stress response.

Objective To observe the effects of Eldepryl on expressions of tyrosine hydroxylase (TH) and glial cell line-derived neurotrophic factor (GDNF) in substantia nigra and striatum in Parkinson’s disease (PD) and to explore the protective mechanism of Eldepryl on dopaminergic neuron . Methods Healthy male Sprague-Dawley (SD) rats (n=72) were randomly divided into control group, model group and Eldepryl group (n=24 in each group). Each group was divided random?ly into 2 subgroups as 4 day treatment group and 8 day treatment group (n=12 in each subgrop). Pakinson’s disease model was established by injecting rotenone subcutaneously back the neck, rats in the control group were injected with an equal vol?ume of sunflower oil subcutaneously at the same location. Rats in the Eldepryl group were then given Eldepryl 0.5 mg·kg-1 in?tragastrically every day for 4 or 8 consecutive days and rats in model group and control group were given an equal volume of saline instead. The expression of TH and GDNF in substantia nigra and striatum were detected by immunohistochemistry and Western blotting. Results Immunohistochemistry and Western blotting showed that strong expression of TH positive cells with little expression of GDNF positive cells were seen in substantia nigra and striatum in rats of control group, and there was no significant difference between subgroup of 8 day treatment and 4 day treatment within control group. The expression of TH cells and GDNF were both significantly reduced in model group compared with those in control group (both P<0.05), and there was no significant difference between subgroup of 8 day treatment and 4 day treatment within each group. The ex?pression of TH positive cells were significantly reduced in Eldepryl group compared with those in control group, and were sig?nificantly increased compared with those in model group. The expression of GDNF positive cells were significantly increased in Eldepryl group compared with those in control group and model group (all P<0.05). And there were significantly more ex?pression of TH positive cells and GDNF positive cells at subgroup of 8 day treatment compared with those at subgroup of 4 day treatment within Eldepryl group with (all P<0.05). Conclusion These data suggest that Eldepryl can protect the dam?age of dopaminergic neurons in substantia nigra and striatum of PD rats. And its therapeutic mechanism may be associated with increased expression of GDNF.

Objective To analyze risk factors for the perioperative complications and death following hip fracture in the elderly. Methods The present study included 1352 elderly patients (≥65 years) who had received hip fracture surgery from January 2010 to June 2015 in Huadong hospital affiliated to Fudan University. Their clinical data were analyzed to determine risk factors for perioperative complications and death. Results Factors significantly affecting the perioperative complications included gender, preoperative serum albumin, ASA grade (≥Ⅲ), cardiac functional grade (≥Ⅲ), respiratory system disease and blood transfusion. Factors significantly affecting the death included preoperative serum albumin, ASA grade (≥Ⅲ), cardiac functional grade (≥Ⅲ) and blood transfusion. Multivariate Logistic regression analysis revealed that the independent risk factors for perioperative complications included gender (B=-0.686, P=0.019), preoperative serum albumin (B=-0.808, P=0.006), cardiac functional grade (≥Ⅲ, B=1.181, P=0.004), blood transfusion (B=0.890, P=0.004) and respiratory system disease (B=3.118, P=0.000);while the independent risk factors for death included preoperative serum albumin (B=-2.516, P=0.000) and blood transfusion (B=1.396, P=0.010). Conclusions In elderly patients undergoing hip fracture surgery, the independent risk factors for perioperative complications included gender, preoperative serum albumin, cardiac functional grade, blood transfusion and respiratory system disease, while the independent risk factors for death included preoperative serum albumin and blood transfusion. Perioperative risk assessment and prevention are the keys of better prognosis.

Objective To analyze the papers published by domestic scientific research workers in order to improve the academic level of their papers. Methods The papers published by over 3000 domestic scientific research workers were investigated with questionnaires. Their motives to publish papers and the relation between the number of pub-lished papers and the assessment of their performance were analyzed. Results The number of papers published by domestic scientific research workers was increased. However, their academic level was to be further improved. Over quantization of the assessment mechanisms for scientific research increased the external motives to publish papers, thus leading to the insufficient internal motives of them to engage in scientific research. Conclusion A loose and comfortable academic environment should be created for the scientific research workers in order to initiate their in-ternal motives to publish papers. Over quantization of the assessment mechanisms for scientific research should be changed in order to reduce the external motives of domestic scientific research workers to publish papers. Innovative and cultural environment should be created in order to improve the soft power of scientific research in our country.

Objective To investigate Aβ42 and P-tau levels in cerebrospinal fluid (CSF) of patients with mild cognitive impairment (MCI). Methods CSF of 25 cases of MCI and 14 cases of cognitively normal (CN) were investigated. The CSF levels of Aβ42 and P-tau were detected by ELISA method. Correlation analysis was used to analyze the correlation between P-tau level and MMSE score in MCI. Results The CSF level of Aβ 42 was higher and P-tau was lower in MCI than CN group(P<0.05). P-tau level in MCI was also negatively correlated with MMSE score (P<0.05). Conclusion Aβ42 and P-tau levels in CSF may be valuable biological markers in the diagnosis of MCI. P-tau level in CSF of MCI may be related to the severity of cognitive impairment.

Objective To evaluate the inverse distance weighted(IDW) in revealing the characteristics of spatial distribution of water fluoride in Heze City,Shandong Province.Methods A geographic information system (GIS) database of water fluoride was established in Heze City of Shandong Province using the data of endemic fluorosis surveys collected by Endemic Disease Prevention Institute in Shandong Province during 2005-2007.IDW spatial interpolation was applied to predict the distribution of fluoride in drinking water in 139 towns of Heze City.Sensitivity and specificity were calculated.Results Mean water fluoride levels in 10 counties of Heze City were all higher than 1.0 mg,/L,and the water fluoride in Cao County,Juye,Mudan District and Juancheng were higher than 2.0 mg/L.Of all 139 townships of Heze City,129 were higher fluoride townships where fluoride was ＞ 1.0 mg/L,10 were lower fluoride townships(≤ 1.0 mg/L).IDW spatial interpolation showed that the water fluoride of most areas in Heze City were ＞ 1.0-2.0 mg/L.The areas with water fluoride of ＞ 2.0-3.0 mg/L were mainly located in eastern Juancheng,northern Mudan District,north-central Chengwu,central and southern Juye,southeastern part of Caoxian and eastern part of Shan Town.Regions of water fluoride ＞ 3.0 mg/L were mainly distributed in Xieji and Wanfeng towns of Juye County,Jishan town of Juancheng County,Sunlaojia town of Caoxian and Dusi town of Mudan County.The internal verification results showed that the sensitivity,specificity and overall accuracy rate of IDW used for predicting water fluoride content was 100.00％ (129/129),10.00％ (1/10) and 93.53％ (130/139),respectively.While the external verification results showed that the sensitivity,specificity and overall accuracy rate of IDW for predicting water fluoride content was 100.00％(31/31),11.11％(1/9) and 80.00％(32/40),respectively.Conclusion With the application of IDW interpolation,it is feasible to infer the overall spatial distribution based on the monitoring data,and to reveal the spatial characteristics of water fluoride in Heze City,Shandong Province.
