AIM:To explore the protective effects of atorvastatin on blood brain barrier (BBB) in cerebral is-chemia-reperfusion ( IR) injury and the potential mechanisms involved .METHODS: SD rats were divided into sham group, IR group and atorvastain group .Intraluminal suture method was used to establish cerebral IR model , and the ische-mic brain was reperfused for 72 h after the occlusion.The rats in atorvastatin group were administered with atorvastatin (20 mg? kg-1? d-1 ) by gavage once a day for 3 consecutive days after operation .At 72 h after reperfusion , neurological func-tion scores, the water content of the brain tissue , Evans blue (EB) content of ischemic hemisphere , the expression of tight junction ( TJ )-associated protein occludin and inflammation factor phosphatidylinositiol 3-kinase-p110 gamma ( PI3K-p110γ) were tested and analyzed .RESULTS: In IR group, the rats showed elevated neurological function scores ( P<0.01), brain tissue water content (P<0.01) and EB content (P<0.01), accompanied with the down-regulation of oc-cludin expression (P<0.01) and up-regulation of PI3K-p110γ(P<0.01) at 72 h after reperfusion.Compared with IR group, decreased brain edema (P<0.01) and EB leakage (P<0.01) were observed in atorvastatin group , accompanied with increased occludin expression (P<0.01) and decreased PI3K-p110γexpression (P<0.01).However, no statistical difference of the neurological function scores between the 2 groups was observed .CONCLUSION:Atorvastain attenuates cerebral IR injury , which may be associated with the inhibition of inflammatory reactions and the up -regulation of TJ-asso-ciated proteins to maintain the stability of BBB .

Objective To explore the method and effect of computer simulative model of lying-in women in the teaching of gynecological nursing. Methods We separated 171 nursing students in grade 2005 into the control group (85 students) and the experimental group (86 students). For the experimental group the teaching method of computer simulative model of lying-in women was used. For the control group we used the traditional teaching method. The effects of two teaching methods were compared. Results The examination achievement of the experimental group was more than that of the control group and 93% nursing students of grade 2005 approbated this teaching method. Conclusions Introducing computer simulative model of lying-in women into the teaching of gynecological nursing can not only improve the effect of teaching, stimulate studying interest and cultivate unity and cooperation ability.

Objective To evaluate the differences of clinical features,neuroimaging,angiography and laboratory findings between different stroke subtypes according to TOAST criteria in elderly patients.Methods 91 patients (aged ≥ 80 years) with acute ischemic stroke were retrospectively reviewed in Departement of Neurology from April 2009 to August 2010.Subtypes of ischemic stroke were analyzed according to the classification of TOAST.Risk factors,clinical manifestations,complications,prognosis,neuroimaging,cerebrovascular lesions,and laboratory findings of different TOAST subtypes were compared.Results Large-artery atherosclerosis (LAA) (34/91) was the most common cause of acute ischemic stroke in elderly patients,and most criminal lesions (25/34) located at the intracranial arteries.In the LAA group,patients with intracranial (25/34) or extracranial (12/34) occlusive diseases were more than those in other groups.Patients with cardioembolism (CE) had lower lipid levels.In the CE group,patients with poor shortterm prognosis (7/15) were more than in the LAA or small-artery occlusion (SAO) group,and patients with severe cerebral edema (4/15) were more than those in other groups.In patients of the SAO group,complications occurred infrequently (4/20),and none had poor short-term prognosis.Conclusions There were some differences among different TOAST subtypes in clinical features,neuroimaging,cerebrovascular diseases,and laboratory findings.The clinical significance of our findings needs to be explored further.

Objective:To study the relationship between gingival thickness(GT)and the underlying alveolar bone thickness(BT)in maxillary anterior region and the distance from cemento-enamel junction(CEJ)to alveolar crest.Methods:30 young volunteers with healthy gingiva were included.GT was measured at 2mm below the CEJ,buccal BT were measured at 3 locations:2,4 and 6 mm below the alveolar crest respectively,the distance from CEJ to alveolar crest were measured by CBCT and clinical direct measure respectively. Results:The correlation coefficient (r)values between GT and BT at 2,4 and 6 mm below alveolar crest were 0.493,0.383 and 0.342 (P <0.001 )respectively,the r value between GT and the distance from CEJ to alveolar crest was -0.21 3(P <0.01 ).No statistically significant difference was observed between CBCT and clinical measurements(t =-0.521 ,P =0.603).Conclusion:There is positive correlation between GT and BT at 2,4 and 6 mm below alveolar crest and negative relation between GT and the distance from CEJ to alveolar crest.

Objective To explore the biomechanical characteristics of the pharynx in patients with aspiration after radiotherapy for nasopharyngeal carcinoma (NPC).Methods Clinical data on NPC patients with dysphagia admitted between July 2011 and June 2015 were retrospectively analyzed.Twenty-three patients were found who had received videofluoroscopic swallowing studies (VFSSs) and whose pharyngeal pressure and upper esophageal sphincter (UES) relaxing were tested using high-resolution solid-state manometry (HRM).The cases were divided into an aspiration group and a non-aspiration group according to the VFSS results.Differences in biomechanical parameters between the 2 groups when taking food of different viscosity were compared.Results Patients with aspiration had significantly higher UES residual pressure when taking thick liquids (20.1± 14.3 mmHg) and paste (18.0± 14.3 mmHg) than patients not aspirating (9.3±9.2 mmHg and 7.2±8.9 mmHg for thick liquid and paste respectively).But no significant difference in average pharyngeal pressure between the two groups was observed.Conclusion Aspiration after radiotherapy may be correlated with increased UES residual pressure.

OBJECTIVE: To observe the protective effect of Huaxia shallot preparation on human umbilical vein endothelial cell (HUVEC) injury induced by oxidized low density lipoprotein (Ox-LDL) in vitro. METHODS: Ox-LDL was prepared and identified, and HUVECs were cultured. After 2-hour intervention of different drugs and 24-hour following intervention of Ox-LDL, the number of HUVECs was observed by phase contrast optical microscope and the activity of the HUVECs was observed by methyl thiazolyl tetrazolium (MTT) technique. Superoxide dismutase (SOD) activity and nitric oxide (NO) content were assayed by respective kit. The protein expressions and mRNA levels of peroxisome proliferators activated receptor gamma(PPAR-gamma) and endothelial nitric oxide synthase (eNOS) were measured by western blot technique and reverse transcription polymerase chain reaction (RT-PCR). RESULTS: Ox-LDL could increase the apoptosis rate of the HUVECs and decrease the NO release as compared with the blank control group (P<0.05). These effects induced by Ox-LDL were all significantly inhibited by Huaxia shallot preparation. It could up-regulate the protein expressions and mRNA levels of PPAR-gamma and eNOS significantly (P<0.05). Huaxia shallot preparation could decrease the apoptosis rate of the HUVECs. CONCLUSION: Ox-LDL may be involved in the initiation and progression of atherosclerosis by injuring the endothelial cells directly and may cause the endothelial dysfunction. Huaxia shallot preparation can protect against Ox-LDL induced endothelial cell injury by up-regulating the protein expressions and mRNA levels of PPAR-gamma and eNOS. It suggests that Huaxia shallot preparation may play a role in the prevention and treatment of cardiovascular disease.

Objective: To investigate the prevalence of scoliosis and identify the influencing factors among children and adolescents in Jiaxing City, Zhejiang Province, so as to provide insights into the management of scoliosis among children and adolescents. Methods: The fourth, fifth and sixth grade primary school students and the first, second and third grade junior high school students were selected using the stratified cluster sampling method in Jiaxing City in 2019. Students' demographic features, diet habits, physical activity and learning environments and habits were collected using questionnaire surveys. Scoliosis was screened using whole-spine X-ray scans in an upright position, and the factors affecting scoliosis were identified using multivariable logistic regression analysis. Results: Valid surveys were completed among 2 568 students, including 1 352 boys ( 52.65% ) and 1 216 girls ( 47.35% ), and there were 1 335 primary school students ( 51.99% ) and 1 233 junior high school students ( 48.01% ). A total of 93 students were detected with scoliosis, with a prevalence rate of 3.62%. Multivariable logistic regression analysis identified age ( OR=0.826, 95%CI: 0.710-0.960 ), gender ( OR=2.079, 95%CI: 1.343-3.221 ) and vigorous physical activity in the past 7 days ( OR=2.514, 95%CI: 1.248-5.063 ) as factors affecting scoliosis among primary and junior high school students. Conclusions The prevalence of scoliosis is high among primary and junior high school students in Jiaxing City. Age, gender and physical activity may affect the risk of scoliosis. Scoliosis screening is recommended to be included in routine healthy

This article was aimed to study the therapeutic effect of Chinese medicine Kun-Bao-W an (KBW) on sleep disorders among ovariectomized mice. A total of 60 female KM of adult mice were randomly divided into four groups, which were the sham-operated group, model group, diazepam group, and KBW group, with 15 rats in each group. Rats in the sham-operated group were only removed small amount of fatty tissue around the ovaries. Bilateral oophorectomy was given on mice in other groups. In the KBW group, 28 days after the operation, KBW was intragastrically administered (1.667 g·kg-1) every day for 28 days. Mice in the diazepam group were intragas-trically administered (1.25 g·kg-1) 1 h before testing. The observation was made on effects of KBW on locomotor activity, sleeping time of mice induced by pentobarbital sodium and the organ coefficients of uterus. The results showed that compared with sham-operated group, locomotor activity and rearing behavior increased obviously in the model group (P < 0.01). The diazepam group can significantly reduce locomotor activity in ovariectomized mice (P < 0.01), and decrease the number of rearing behavior mildly with no statistical difference. KBW can reduce lo-comotor activity mildly but without effect on rearing behavior in ovariectomized mice. Diazepam can markedly pro-long the pentobarbital sleep time in ovariectomized mice (P < 0.01). KBW can prolong the pentobarbital sleep time and shorten the process of falling into sleep mildly with no statistical difference. There was no significant ef-fect on organ coefficients of uterus in ovariectomized mice by KBW or diazepam. It was concluded that KBW had mild effect on improving sleep disorders in ovariectomized mice.

This article was aimed to study the sedative and hypnotic effects of different eluents of Shuangxiatang (SXT). The effects of SXT water decoction, water eluent, 20%, 70% and 95% alcohol eluent on spontaneous ac-tivity and the sleeping induced by subthreshold dose of pentobarbital sodium were measured. The results showed that the SXT decoction, 20% and 95% alcohol eluent can significantly decrease the number of rearing in mice with the percentage of 78.5%, 78.3% and 62.5%, respectively. SXT water eluent and 70% alcohol eluent can significantly decrease the spontaneous activity of mice (P < 0.01), the number of rearing (P < 0.01) and grooming time (P < 0.05). SXT water decoction can significantly shorten sleep latency (P < 0.05), prolong sleep time (P <0.05), and increase rates of sleeping in mice. SXT water eluent can significantly shorten sleep latency in mice (P< 0.05), increase rates of sleeping in mice. SXT water decoction and water eluent have the sedative and hypnotic effects. And the effects are more than alcohol eluents.
