Objective:To investigate prevalent aeroallergens in ChongQing and their sensitization risk factors in children with allergic diseases,especially asthma.Methods:Skin prick tests with 13 standardized aeroallergens and questionnaires were used.A total of 298 patients,aged between 4~15 years and were diagnosed with allergic asthma and or allergic rhinitis,were investigated.Results:The total positive rate of allergen was 84.9%(253/298).The prevalence of aeroallergens were following:the first was house dust mite,cockroach followed,the third one was cat dander;the positive family history of asthma was 69.6%(116/230),asthma and rhinitis accounted for 67.2%(78/116)。Multivariate logistic regression analyses revealed that house dust mite was an independent risk factors for asthma(odds ratio Value(OR):2.602,95%CI:1.672～7.488),air conditioning had strong relationship with it(OR:1.659,95%CI:1.139～5.942).Conclusion:House dust mite is the major allergen of allergic diseases,especially asthma in ChongQing.Air conditioning is one of important risk factors for house dust mite sensitization.

Objective:To prepare Pingwei dispersible tablets and establish a method for the determination of atractylodin. Meth-ods:HPLC was performed on a Kromasil C18 column(250 mm × 4. 6 mm,5 μm)using methanol-water(75:25)as the mobile phase at a flow rate of 1 ml·min-1 . The detection wavelength was at 340nm. The column temperature was 30℃ and the injection volume was 10 μl. Results:The optimized formula of the tablets was as follows:the proportion of inner disintegrant microcrystalline cellulose,out-side disintegrant carboxymethyl cellulose sodium and HPMC was 40%,9% and 2%,respectively. The adhesive was 2% HPMC in 70% ethanol,and 1. 5% magnesium stearate was used as the lubricant. The linear range of atractylodin was 0. 100 6-0. 503 0 μg(r=0. 999 9),and the average recovery was 99. 3%(RSD=0. 9%,n=6). Conclusion:The formula and the preparation process of the tablets are reasonable and the content determination method is simple,accurate and specific,which can be used in the quality control of Pingwei dispersible tablets.

Objective To explore the anti-cancer function of old drugs from the perspective of the concept of Chinese herbal nature combination, and provide method and a new thinking style for the new function discovery from old drugs under the guidance of the theory of traditional Chinese medicine (TCM). Methods Using lung cancer with qi and yin deficiency as the example, the therapeutic principles of TCM anti-lung cancer treatment were analyzed and Chinese herbal nature combination patterns (CHNCP) for cancer treatment were extracted based on the relationship between function and Chinese herbal nature combination. The chemical medicines were re-screened with the cancer CHNCP and the candidates were identified. Results The therapeutic principle of TCM anti-lung cancer treatment is invigorating qi and nourishing yin. Fifteen chemical medicines were identified as the anti-cancer candidates, including 2 anti-cancer drugs being used in clinics and 4 drugs having the anti-cancer activity. Conclusion The method for finding the anti-cancer function of old drugs based on the Chinese herbal nature combination is feasiable, which provide new clues for application of old drugs.

Objective To investigate the changes of detection rates of IL-2,IL-6 and serum anti-Chlamydia immunodominant protein antibody in the patients with Chlamydia trachomatis genital tract infection.Methods Sixty women with genital tract infection (CT group) and 60 healthy women (control group) were selected in our hospital from January to May 2016.The serum levels of IL-2,IL-6 and anti-Chlamydia immunodominant protein and IL-2 and IL-6 levels in cervical secretions were detected in the two groups.Results The IL-2 and IL-6 levels of serum and cervical secretions in the CT group were significantly higher than those in the control group,the difference was statistically significant (P<0.05);the positive detection rates of serum OmcBc antibody,Pgp3 antibody,HSP60 antibody and CTT841 antibody in the CT group were 45.00%,75.00%,23.33% and 38.33% respectively,which were significantly higher than those in the control group,the difference was statistically significant (P<0.05).Conclusion The positive detection rates of IL-2,IL-6 and serum anti-Chlamydia immunodominant protein antibody in the patients with genital tract Chlamydia infection are significantly increased,which has some guiding significance for clinical diagnosis and treatment.

Recently diverse magnetic resonance imaging technology is used in glioma grading,which based on the theory of Gaussian distribution.Diffusion kurtosis imaging emerges as an extension of DWI and DTI,which could reflect the real and actual hydron non-Gaussion distribution of tumor and peritumoral microenvironment.Displaying the correlation with immunohistochemical label Ki-67,DKI convinces more scholars inland and abroad with its practicability.

Objective To study the awareness and behaviors for patients′ privacy protection among undergraduate nurses. Method By using questionnaire, the survey was conducted among 100 undergraduate nurses. Results The score on the awareness and behaviors for patients′privacy protection was (15.84 ± 1.25). There were significant differences in the awareness and behaviors among different internship time, gender and hospitals (all P<0.05). Conclusions Awareness and behaviors for patients′privacy protection among undergraduate nurses are at a medium level. It is a demand to enhance the education on patients′privacy protection , especially to male undergraduate nurses and at the beginning of internship so as to prevent the patient-nurse disputes.

The changes of immune system following stroke mainly includes the local inflammatory responses of brain tissue and the systemic immunological changes, The former may exacerbate brain damage following stroke, the latter may increase the susceptibility to infection, and thus impact on brain function recovery and prognosis. Stroke interferes with the normal balance between the nervous system and the immune system, and its mechanism remains unclear. This article reviews the stroke-indnced immunological alterations and their mechanisms,as well as the corresponding treatment strategies in clinical practice.

Superficial siderosis of the central nervous system is a seldom disease in clinical practice. Its most common clinical manifestations are hearing loss and ataxia. It is a hemosiderin deposition in the surface of the brain and spinal cord after chronic subarachnoid hemorrhage. Magnetic resonance imaging can make the diagnosis. However, further research and clinical verification are needed.

The patients with stroke is often accompanied by malnutrition, its causes include eating less, increased catabolism, and intestinal dysfunction, etc. Malnutrition can not only aggravate the extent of brain damage in patients with stroke, but also increase the incidence of complications, and thus affecting the course and prognosis of stroke. Therefore, correct evaluation of the nutritional status in stroke patients, choosing the appropriate nutrient timing and nutritional support methods have important significance. Among a variety of nutritional assessment methods, the scored Patient-Generated Subjective Global Assessment can quickly identify malnutrition in stroke patients. Early enteral nutrition support, including oral nutritional supplements, nasogastric tube feeding and percutaneous endoscopic gastrostomy, can significantly improve the prognosis in stroke patients. Among them, nasogastric tube feeding is the first choice for nutritional support in stroke patients.

Objective To study the influence of serum containing Ziqi Ruangan Pill on inhibitory effect of alcohol LO2 and to investigate the regulation on apoptosis related genes and the protective mechanism for LO2. Methods Rabbit sera saline containing Ziqi Ruangan Pill was prepared. The apoptotic LO2 model was established by being cultured with alcohol. The effect of serum on the model was detected by MTT method. Identification of apoptosis was carried out using flow cytometry and Hoechst3325 fluorescent staining. The expression of apoptotic inducing gene,casepase3 and NF-?B was detected by Real-time RT PCR and Western-Blot. Results The serum containing Ziqi Ruangan Pill could regulate the expression of the casepase3,NF-?B and reduce the apoptosis. Conclusion Ziqi Ruangan Pill can protect the LO2 by regulating the expression of apoptosis stimulative gene casepase3 and NF-?B.
