Objective To investigate the correlation between serum S100B, IL-6 and intracranial pressure in patients with severe craniocerebral injury.Methods 81 cases of patients with severe brain injury in our hospital from August 2012 to April 2016 were selected,intracranial pressure was monitored immediately after admission to calculate the average daily ICP level ,and venous blood were collected after craniocerebral injury 6,12,24,48, 72 hours.Detection of serum S100B protein and IL-6 levels,and the correlation analysis with the level of intracranial pressure.Results Patients with severe craniocerebral injury S100B levels increased gradually after injury, reached the peak at 24 hours, then decreased gradually; while patients with IL-6 and intracranial pressure after injury gradually increased, the difference was statistically significant in different time points among the S100B,IL-6 and intracranial pressure levels (P<0.05).Conclusion The changes of intracranial pressure after severe craniocerebral injury were proportional to the levels of serum S100B and IL-6,S100B and IL-6 can reflect the changes of intracranial pressure,intracranial pressure changes predicted by S100B plasma concentration in 48 hours were more sensitive than those in the same concentration of IL-6.

This article made a discuss on the importance of correct recognition and objective evolution of traditional Chinese medicine in the new era from such aspects as elements that promoting the development of traditional Chinese medicine(TCM),insufficiencies that restricting TCM development,and routes that solving the problems encountered in TCM development.

Methaqualone and 2-methyl-3 [2- (hydroxymethyl) phenyl]- 4 (3H) quinazolinone (metabolite I) concentrations in human serum wereanalyzed quantitatively by reverse high performance liquid chromatography (RP-HPLC). The concentrations of methaqualone ranging from 1-35?g/ml were in good linear relationship(Correlation coefficient r = 0. 9980, regression line y = 0. 06324x-0. 1029), The average recovery of methaqualone reached as high as 102.08?9. 987(SD)% (n= 5). The detective limit was 1 ng. The relative quantity of metabolite I was determined according to the linear concentration of methaqulone. RP-HPLC assay is proved to be useful in determening blood methaqualone and metabolite I concentrations in forensic toxicology.

Objective: To study the expressions of p16INK4A, Brn3a, telomerase and human cervical cancer oncogene (HCCR) in cervical intraepithelial neoplasia (CIN), and to estimate their values for predicting the progression of cervical lesions. Methods: Paraffin specimens of 262 cases were all from the residue of patients' liquid-based cytology test (LCT) samples, including 30 normal cases, 80 cases of atypical squamous cells of undetermined significance (ASCUS), 72 cases of low-grade squamous intraepithelial lesions (LSIL), 50 cases of high-grade squamous epithelial lesions (HSIL) and 30 cases of invasive squamous cell carcinoma. The expression levels of p16INK4A, Brn3a, telomerase and HCCR in these samples were detected using immunocytochemistry. Results: The expression levels of p16INK4A and Brn3a in ASCUS and LSIL specimens were significantly higher than those in normal cells (P < 0.05). Compared to ASCUS and LSIL, the expression levels of p16INK4A, Brn3a, telomerase and HCCR in HSIL and invasive squamous cell carcinoma were significantly higher (P < 0.05). Among ASCUS, both the expression of p16 INK4A in cases that had pathological diagnosis of CIN1 and the expressions of p16INK4A and Brn3a in cases that had pathological diagnosis of CIN2+ were significantly higher than those had pathological diagnosis of chronic cervicitis or cervical condyloma (P < 0.05). Among LSIL, the expressions of p16INK4A and Brn3a in cases that had pathological diagnosis of CIN2+ were significantly higher than those had pathological diagnosis of chronic cervicitis or cervical condyloma (P < 0.05). Moreover, the expressions of p16INK4A and Brn3a in ASCUS and LSIL had a strong relationship (r = 0.580, P < 0.001). Conclusion: The expression levels of p16INK4A, Brn3a, telomerase and HCCR can help distinguish HSIL and invasive squamous cell carcinoma from ASCUS and LSIL, and combined detection of p16INK4A and Brn3a maybe assist in predicting the progression of ASCUS and LSIL.

OBJECTIVE: To evaluate the effect of patient education on patients with allergic rhinitis (AR). METHOD: From January 2009 to December 2013, 100 cases of allergic rhinitis were treated. The patients were randomly divided into experimental group or control group by Stochastic tables law,50 patients in control group accepted only drug treatment, 50 patients in experimental group accepted both drug treatment and patient education. The difference in compliance with treatment, treatment effect, incidence of adverse drug reactions and complications, average costs and times of treatment between two groups were evaluated by the rhinoconjunctivitis quality of life questionnaire (RQLQ) score. The independent sample t-test and χ2 test were used for statistical analysis. RESULT: The patients of experimental group showed more positive attitude to treatment compared to the patients of control group (P < 0.01). The average scores of each classification and overall symptoms after treatment in experimental group were lower than those in control group (P < 0.05). The incidence of adverse drug reactions (nose-bleed, dry nose,nasal mucosa ulcer)and complications in patients with AR (asthma, chronic cough, secretory otitis media) in experimental group was lower than that in control group, with statistically differences (P < 0.05). The average times of treatment and costs of diagnosis and treatment(calculation of budesonide nasal spray)in experimental group were significantly lower than those in control group (P < 0.01). The total score for RQLQ and the scores of seven dimensions in experimental group were lower than those in control group (P < 0.05). CONCLUSIONS Patient education can help the patients with AR to cooperate actively with treatment, to reduce the incidence of adverse drug reactions and AR complications, and to save medical costs and improve the quality of life.
