World Science and Technology-Modernization of Traditional Chinese Medicine 2014;(7):1629-1632
This study was aimed to observe the clinical curative effect of Thesium Chinese tablets in the treatment of chronic bronchitis (syndrome of phlegm heat in the lung). A total of 100 cases of chronic bronchitis (syndrome of phlegm heat in the lung) were randomly divided into two groups. The control group was treated with anti-inflamma-tion, relieving cough and asthma, phlegm removing and oxygen inhalation, maintenance of water electrolyte balance and other symptomatic treatment. In the treatment group, on the basis of treatments in the control group, Thesium Chinese tablets were given at the dosage of 1.6 geach time, 3 times a day. Both groups were treated for 1 course of 10 days. The results showed that clinical symptoms and traditional Chinese medicine (TCM) syndromes of quantizing integral were improved after treatment in both groups. And the therapeutic effect of treatment group was significantly better than the control group (P< 0.01). Thesium Chinese tablets can effectively shorten the time of clinical symptom improvement time, obviously improve the level of Ig among elderly patients with acute exacerbation of chronic bron-chitis, and enhance the immune function. It was concluded that the Thesium Chinese tablets can effectively improve the quality of life among patients with chronic bronchitis (syndrome of phlegm heat in the lung).

Objective To investigate the effect of mechanical ventilation in acute organophosphorous pesticide poisoning(AOPP) with respiratry failure. Methods Forty from forty-two AOPP patients with respiratry failure were treated with mechanical ventilation(MV) ,gastrolavage and other methods. Five minutes before mechanical ventilation and two hours after mechanical ventilation, patients' heart rate (HR), systolic blood pressure (SBP), arterial partial blood pH, oxygenation index, the pressure of carbon dioxide (PaCO2) were compared. Results Patients' HR was increased ( P<0. 05 ), SBP was increased ( P<0. 01 ), arterial partial blood pH was increased( P<0. 01 ), oxygenation index was increased(P<0. 01 ) ,PaCO2 was decreased(P<0.01 ). Thirty nine cases were cured,three cases dided. Conclusion Mechanical ventilation can effectively treat the AOPP patients with respiratry failure.

Objective: To analyse correlation of bispectral index,spectral edge frequency of electroencephalogram with midazolam-induced sedation. Method: 30ASA grade Ⅰ-Ⅱ adult patients, undergoing elective surgery under regional anesthesia were randomly devided into three groups according to intravenous bolus doses of midazolam,i, e. group Ⅰ:0.05mg?kg~(-1),group Ⅱ:0.1mg?kg~(-1),group Ⅲ:0.2mg?kg~(-1). After an intravenous bolus dose of mida zolam was administered,both bispectral index (BIS), 95% spectral edge freguency (SEF) of electroencephalogram were monitored and their correlation with midazolam induced sedation was analysed. Result: Both BIS and 95% SEF-correlated with midazolam-induced sedation significantly (r= 0.86,0.73, P

In the present study, the specifically knockdown models of P-gp or MRP2 were constructed by using a series of chemically synthesized small interfering RNA (siRNA) in vitro. The expression of P-gp and MRP2 was measured by real-time PCR and Western blot, and the function was evaluated by applying P-gp and MRP2 substrate, rhodamine and methotrexate. The results showed that MRP2 siRNA-3 or P-gp siRNA-2 significantly decreased the mRNA expression of MRP2 or P-gp, the inhibition ratio was 68% or 84%; MRP2 siRNA-3 or P-gp siRNA-2 at a dose of 80 nmol x L(-1) significantly reduced the protein expression of MRP2 or P-gp at 48 h after treatment, the inhibition ratio was 62% or 70%. Meanwhile, other transporters were not influenced by siRNA. When pretreatment with MRP2 siRNA-3 or P-gp siRNA-2, the efflux of methotrexate or rhodamine decreased significantly and the intra-cellular concentration increased. The results suggested that chemically synthesized siRNA could significantly inhibit the expression and function of MRP2 and P-gp, and the model of RNAi in vitro could be used to evaluate the role of efflux transporters in transportation of drugs.

Objective To explore the imaging characteristics of the ovarian thecoma-fibroma.Methods The clinical imaging characteristics of 25 patients with thecoma-fibroma were retrospectively analyzed. Results A total of 27 lesions were seen in 25 patients, and the maximum diameter of the tumors was 1.2 - 15.0 cm, with an average diameter of 6.9 cm. The tumors whose maximum diameter larger than 6 cm were mainly as cysticsolid. Twenty-six lesions were well-defined margin, and 14 lesions were round and oval masses, 9 lesions were lobulated masses, 3 lesions were irregular masses, and 1 lesion presented with unclear boundary. A total of 10 lesions in 9 cases were performed with CT scan, and the density was similar to uterine muscle density. In MRI scan of a total of 17 lesions of 16 cases, all lesions showed hypointensity on T1WI. On T2WI, 8 lesions showed slightly hyperintensity, 7 lesions appeared slight hypointensity, and 2 lesions appeared significantly hypointense. Eight lesions showed slit hyperintensity. Enhancement scanning was performed in seven cases. Five cases showed mild to moderate enhancement, 1 case was enhanced obviously, and 1 case was not strengthened. Conclusions The imaging findings of the ovarian thecoma-fibroma have somewhat features and can indirectly reflect pathology of tumor. Combined with the clinical data, imaging characteristics are is helpful to the diagnosis and differential diagnosis of the disease.

AIM: To observe the levels of triglyceridemia(TG),uricemia(UA),glycemia(GLU),the activity of 3-glyceraldehyde phosphate dehydrogenase(GAPDH) in blood and the gene expression in the liver in the animal model of hypertriglyceridemia,hyperuricemia and hyperglycemia.METHODS: SD rats were randomly divided into three groups,control group,fructose group,fructose and fenofibrate treated group.Rats in control group were fed with standard chow.Rats in fructose group were fed with high fructose diet.Rats in fructose and fenofibrate group were fed with high fructose diet,and treated with fenofibrate 100 mg?kg-1?d-1 by intragastric administration at the same time.Rats in control group and fructose group were given distilled water by intragastric administration.The levels of TG,UA and GLU were detected.Improved method was used to measure the activity of GAPDH.Quanti Gene technology was applied to determine the transcriptional level of GAPDH mRNA.RESULTS: During 7-28 d,the level of TG in fructose group was significantly and persistently high.During 14-28 d,the level of UA was higher.The level of GLU higher than that in control group was only observed at 28th day.The GAPDH activity change in blood and the expression in liver were significantly lower than that in norma1 during 7-28 d.Fenofibrate had the effect on reducing TG only at 7th day and reduced the level of GLU significantly at 28th day.Fenofibrate also increased the GAPDH activity in blood and the expression in liver at 7th day.CONCLUSION: ① The level of TG is significantly and persistently high in the early days by feeding with excessive fructose.The levels of UA and GLU are higher with the time cause of the model development.② The significantly higher level of TG,UA and GLU may be correlated with the reduction of the GAPDH activity in blood and the expression in liver.③ Fenofibrate has the effect of reducing the TG level only in the condition of hypertriglyceridemia,but not in the condition of accompanying hyperuricemia and hyperglycemia.④ The mechanism of reducing the TG level by fenofibrate may be correlated with the increase in GAPDH activity in blood and the expression in liver.
