ABSTRACT
OBJECTIVE:To study the formulation of Xiqingguo buccal tablet,optimize the proportion and quantity of main materials. METHODS:Using appearance,hardness,dissolution and taste as investigation indexes,orthogonal design was adopted to optimize the proportion and quantity of main thinner(lactose,mannitol),wetting agent(ethanol),lubricant(magnesium stea-rate),flavoring agent(aspartame),and critical relative humidity was detected. RESULTS:By wet granulation,the optimal formu-lation were as follows as the ratio of lactose and mannitol was 1:3,ethanol volume fraction was 60%,the dosage of menthol, magnesium stearate,aspartame and orange essence was 0.4%,0.9%,2.0%,0.4%;it was proven that the total score of 3 batches of samples were 2.67,2.67,2.70 (RSD=0.65%,n=3),respectively. The critical relative humidity of granule was 60%. CON-CLUSIONS:The Xiqingguo buccal tablet prepared by optimal prescription meets the requirements.
ABSTRACT
Objective The effect of hypoxia inducible factor-1α( HIF-1α) , p-glycoprotein ( p-gp) and human papillomavir-us(HPV) infection on non-small cell lung cancer (NSCLC) and their interrelationship are still not clear .The article aimed to study the relationship between HIF-1αand P-gp, their role in the occurrence , development and multidrug resistance of NSCLC , as well as the in-terrelationship among HIF-1α, p-gp expression and HPV infection . Methods By using immunohistochemistry , the expression of HIF-1αand p-gp was detected in 60 NSCLC tissues and 20 benign lung disease tissues .PCR was employed to detect the expression of HPV16/18 DNA. Results The positive expression rate of HIF-1αand p-gp was 48.3% and 60.0% respectively in NSCLC, but there was no positive expression of HIF-1αand p-gp detected in the benign lung disease group (P0.05).The positive expression rate of p-gp in HPV DNA positive group and negative group was 64.0% and 57.1%respectively, which showed no significant difference too (P>0.05). Conclusion HIF-1αand p-gp are involved in the occurrence, development and multidrug resistance of NSCLC .HPV infection may be one of the etiological factors in the carcinogenesis of NSCLC . However , neither the HIF-1αexpression nor the p-gp expression is associated with HPV infection .
ABSTRACT
Objective:This study aims to explore the relationship between respiratory tract of chemotactic cytokines and nitric oxide levels of infection.Methods:40 cases of patients as the observation group during August 2012 to August 2013 were selected in our hospital respiratory department of internal medicine were respiratory tract infection , healthy subjects 30 cases as the observation group,the observation group at the time of admission ,admission after 3 d,the 7 d after be admitted to hospital ,hospital of cytokines (TNF-α),nitric oxide (NO) and interleukin (IL-6,IL-17,IL-10) level difference,and were compared with the control groups Results:Patients in the observation group at the time of admission ,admission after 3 d,compared with 7 d after admission,discharge of TNF-α,NO,IL-6,IL-17,IL-10 level differences were statistically significant (F=10.849,P<0.05),with the extension of treatment time,symptoms gradually improved until the patients with respiratory tract infection , can be found in the above indexes all time is gradually decreased;the observation group the 3 d after be admitted to hospital ,the 7 d after be admitted to hospital discharge ,TNF-α, NO,IL-6,IL-17,IL-10 levels were compared with admission differences were statistically significant Conclusion: By measuring the levels of cytokines and NO levels in patients withrespiratory tract infection ,can judge the prognosis of patients.
ABSTRACT
Objective To study the therapeutic effect and significance of Naloxane on the brain function in patients with acute organ phosphorus pesticide poisoning. Methods 106 patients with acute organ phosphorus pesti-cide poisoning were randomly allocated to two groups according to the hospitalized date, the NX group(n=54) and the normal group(n=52). The two groups received the same basic treatment and the dynamic monitor about the changes of the β-EP and MDA levels in each groups, and the NX group was given additional treatment with 0.8 mg Naloxone-intravenous injection every 20 minutes till consciousness recovering or symptoms improved. Results The time of recovering consciousness was (16.71±3.17)h in NX group and (20.84±3.25)h in control group. β-EP and MDA were higher than normal before treatment in all patients (P<0.01), and were significantly reduced after treatment in NX group (P<0.05), the control group had mild change after treatment. Conclusion Relating to the inhibition of oxygen free radicals, Naloxone can reduce time of recovering consciousness and can protect the injured brain of the patients with acute organ phosphorus pesticide poisoning.
ABSTRACT
Objective To investigate the relationship between impaired fasting glucose(IFG) and the distribution of body fat in adolescents.Methods Stratified cluster sampling was used to select 3874 adolescents aged 13-18 years for this cress-sectional study.Measurements included height,weight,waist circumference,hip circumference and fasting plasma glucose (FPG).Family history of diabetes was determined by using a serf-administered questionnaire.Participants were divided into normal fasting glucose group(FPG＜5.6 mmol/L,n=3738) and impaired fasting glucose group (5.6 mmol/L≤FPG ＜ 7.0 mmoL/L,n=136) according to their FPG levels. Results (1) After adjusting for age and sex using covariance analysis,the impaired fasting glucose group showed increased levels of body mass index,weight circumference,waist/hip ratio,waist/height ratio,as compared to the normal fasting glucose group (P＜ 0.05).(2) After the age and gender were adjusted,body mass index,weight circumference,waist/hip ratio and waist/height ratio were positively correlated with FPG level (P＜0.05).Among the partial relation coefficients, that between waist/height ratio and FPG(r'=0.0925) was the highest (3) In multiple regression analyses,age (β=-0.102,P＜0.05),family history of diabetes (β=0.186,P＜0.05) and waist/height ratio (β=0.842,P＜0.05) were consistently associated with FPG.Conclusion Central obesity was an important predictor of IFG in adolescents.Waist/height ratio may be an useful index of central obesity and an important predictor of IFG in adolescents.
ABSTRACT
Objective To discuss the clinical features of trachea and bronchial tuberculosis and estimate the efficacy of the diagnosis of trachea and bronchial tuberculosis by fiberoptic bronchoscopy. Methods Clinical presentations and examination of fiberoptic bronchoscopy findings of 216 patients diagnosed by Olympus electric or fiberoptic bronchoscopy were retrospectively investigated. Results Male of the 216 patients were 95, female were 121, with 1.27 times higher incidence noted in female than in male subjects. An activator dry cough was the most complain in 72.7% , intermittent hemoptysis was in 34.7% , absenting of typical clinical poisoning symptoms of tuberculosis. Atelectasis and shape in lung were the most common chest roentgenographic presentations respectively in 31.0 % and 24.1 %. Chest roentgenographic presentations of 16.7% were normal. Bronchoscopic findings showed that main pathologic changes included 36.1% granulation, 31.0% mucosa inflammation, 24.1% ulceration (or necrosis) and 8. 8% cicatricial stenosis, left lung (56. 2%) was more often affected than right lung (37.6%), left bronchi (26.9% ) was in the first. The pathologic changes affected all of leaf, segment bronchi. One hundred and seventy-eight cases (82.4%) were diagnosed by bronchoscopic biopsy, 68 cases (31.5%) were diagnosed by bronchoscopic brushing examination for acid - fast bacillus. Conclusion The clinical features of trachea and bronchial tuberculosis are non - specific and easy to be misdiag-nosed. It is the main reason to be misdiagnosed that bronchial biopsy is neglected by clinical doctors. Bronchial biopsy should be the most reliable and accurate step to get the definite diagnosis.
ABSTRACT
0.05).Conclusion The increase in the amount of nm23H1 protein expression can play an important role in restraining metastasis of squamous cell lung carcinoma.The heredity instability(MSI and LOH) of nm23H1 gene may not be implicated in expression of the gene and pathogenesis and progression of squamous cell lung carcinoma.
