Objective: To compare the volatile constituents of folium artemisiae argyi in order to provide chemical evidence for quality standardization. Methods: Volatile oil was extracted from folium artemisiae argyi from five sources by vapour distillation and then detected by gas chromatography-mass spectrometer (GC-MS) to identify and semi-quantify its chemical constituents. Results: The folium artemisiae argyi in Qichun (Hubei Province) and Anguo (Hebei Province) contained many volatile constituents, with uniform and stable contents of these volatile constituents. Conclusion: The types and contents of volatile oil of folium artemisiae argyi are varied in different sources.

Objective To analyze the effect of prognosis of psychological counseling combined with early double anti antiplatelet on the treatment of acute cerebral infarction.Methods 76 patients with acute cerebral infarction who were admitted to our hospital from February 2014 to March 2016 were numbered according to their admission order.The patients with even numbers were in the observation group and with the odds number in the control group, 38 cases in each group.The control group were given aspirin and clopidogrel in the early stage, and the observation group were given psychological guidance on the basis of the control group.The prognosis in the two groups was recorded and analyzed.Results The neurological deficit score (NIHSS) and simple mental state score (MMSE) in the observation group (9.16±0.73)points, (25.42±2.00)points were significantly higher in the observation group than those in the control group (12.59±1.05)points, (20.73±2.16)points.And the differences were significant (P<0.05).The level of dailyliving activity index (Barthel) and Hamilton depression (HAMD) in the observation groupwere (80.86±3.29)points, (13.70±1.53)points, respectively, which were better than those in the control group (71.53±3.75)points, (18.53±1.99)points, and the differences were significant (P<0.05).The total adverse reaction rate in the treatment group was 18.42%, slightly higher than 14.29% in the control group, but the difference was not statistically significant.Conclusion Psychological counseling combined with early double antiplatelet intervention has positive effect on the prognosis in the patients with acute cerebral infarction.

Objective To observe the effect of herbs of cleaning away heat,drying dampness and invigorating spleen on insulin resistance and TNF-? of the patients with early stage of type 2 diabetes mellitus.Method Eighty-eight patients with type 2 diabetes mellitus were randomly divided into 2 groups.Forty-four cases of the treatment group were treated with herbs of cleaning away heat,drying dampness and invigorating spleen,and 44 cases of the control group were treated with metformin.The data of their weight,glucose,insulin and TNF-? before and after treatment was compared.Results Glucose and insulin of two groups declined(P

To analyze six cases concerning clinical features, the treatment process and curative effect of Rhinolith. The six patients had unilateral nasal obstruction, three of them were accompanied with purulent nasal discharge, two had blood with them, one patient had repeated hemorrhage of nasal cavity and two patients had developed headache. By using endoscopic, four irregular stones which are yellow, gray and brown were found in the middle and back end. Because of the severe nasal septum deviation and inferior turbinate polypoid, the stone could not be seen clearly but could be touched by aspirator. In sinus CT examination of 6 cases, it showed incomplete irregular shapes and had high density unilateral nasal cavity in the posterior segment. 4 patients had nasal deviation, 3 patients had ipsilateral sinusitis. 4 patients removed their stone by using endoscopy, 2 patients took the stone away after correction of nasal septum. Pathologic diagnosis: rhinolith. Two patients also had exogenous foreign matters which were considered as pseudo nasal stones.

Objective To construct the eukaryotic expression vector with the mutant of hypoxia inducible factor 1α (HIF-1α) that could over express nonhypoxic dependent HIF-1α and investigate its expression in eukaryotic cells PC12. Methods The coding sequence of HIF-1α was amplified from total RNA from the injured spinal cord of rats by means of RT-PCR. Then, overlapping extension PCR was employed to obtain one complete sequence encoding HIF-1α mutant without oxygen-sensitive degradation domain (ODD). By using gene recombination technique, the gene HIF-1α△ODD was inserted into eukaryotic expression vector _pEGFPC1 that contained a reporter gene of enhanced green fluorescent protein. The recombinant plasmid was successfully constructed and transfected into the neural cell line PC12. The expression of HIF-1α△ODD was analyzed by fluorescent observation and Western blot. Results A 2kb gene fragment encoding H1F-1α△ODD was successfully obtained by overlapping extension PCR. On this basis, the recombinant plasmid _pEGFPC1-HIF-1 α△ODD was constructed and testified with restriction enzyme digestion and DNA sequencing. After this recombinant plasmid was transfected into the neural cell line PCI2, both fluorescent observation and Western blot demonstrated that HIF-1α△ODD was over expressed under nonhypoxia conditions. Conclusion The eukaryotic expression vector _pEGFPC1-HIF-1α△ODD is successfully constructed and HIF-1α△ODD over expresses in transfected PCI2 cell lines.

BACKGROUND: The population of male and female adolescents in China accounts for 1/5. Adolescents have much psychological bewilderment,troublesome and even diseases on sexual issues.OBJECTIVE: To investigate the development status quo and the regulation of adolescents' sexual physiology, sexual psychology, sexual knowledge and sexual education.DESIGN: A cross-sectional survey by employing students of junior high school as subjects.SETTING: A clinic for adolescent of a tertiary hospital.PARTICIPANTS: Totally 960 students aged between 14 and 19 years old of three junior high schools in Dalian city were selected as subjects between November and December of 2001.METHODS: Self-complied questionnaire was used in the survey based on the sexual psychological education situation scale for junior and senior high school students. Classes were randomly selected for anonymous survey based on voluntary principle.Answers to sex-related questions and differences between male and female students.RESULTS: The average age of menarche in female students was 12.96years old and the average age of first emission in male students was 13.89years old, which were consistent with the results of similar national researches. The incidence and frequency of masturbation and sexual impulse was significantly higher in males than females. There were significant differences in sexual concept and the understanding of sexual knowledge between males and females. The desire to affiliate with the opposite sex was far more than the real occurrence.CONCLUSION: The understanding of sexual knowledge in adolescent is not satisfied. Students are also not satisfied with the sexual education provided by their schools. Hence, school sexual education for adolescents should be enhanced with the involvement of community.

Objective To investigate relationship between microRNA-200c and ZEB1 in cervical epithelial mesenchymal transition factor. Methods 50 cases diagnosed with cervical cancer whose tumor tissue were taken to be the experiment group.50 cases diagnosed with uterine myoma whose normal tissue were taken to be the control group.ZEB1 and microRNA-200c of uterine tissue were were detected.Results The average level of ZEB1 in the experimental group was significantly higher than that of the control group (P<0.05), and in cervical cancer, lymph node metastasis and the depth of myometrial invasion had statistically significant (P<0.05).In experimental group, microRNA-200c average was lower than control group (P<0.05), and in cervical cancer, different pathological grade group, lymph node metastasis and deep muscular layer infiltration had statistically significant(P<0.05).In experimental group, ZEB1 and microRNA-200c showed negative correlation(r =-0.270 P =0.001).Conclusion The expression level of ZEB1 in cervical cancer is higher, and the expression level of microRNA-200c in cervical cancer is lower, suggesting that the two factors may play an important role in the invasion and metastasis of cervical cancer.The correlation between the two factors suggests that microRNA-200c may be involved in the process of cervical cancer by ZEB1.
