OBJECTIVE:To provide reference for rational drug use in respiratory department. METHODS:ADR/ADE report-ed by respiratory department of a class three grade A hospital during Jan. 2011 to Dec. 2015 from national ADR monitoring system were collected. 2011-2015 ADR/ADE database of respiratory department in a hospital was established and analyzed statistically. RE-SULTS:202 records were gotten,among which 89 cases were male(44.06%)and 113 cases were female(55.94%);the patients’ age approximated normal distribution,the incidence of ADR/ADE was the highest in 61-80 age group (55.94%);the occurrence time of ADR/ADE was mostly lower than 1 h (47.21%);the main route of administration was intravenous drip (71.29%);22 kinds of drugs were involved,and antibiotics took up the lead(43.11%);84 patients(41.58%)used 2 and more kinds of drugs before the occarrence of ADR/ADE;organs/systems involved in ADR/ADE were skin and its appendants (32.86%) and digestive system(26.19%). Most of the ADR/ADE could be cured or recovered after related treatment. CONCLUSIONS:The occurrence of ADR/ADE in respiratory department is related to various factors,of which advanced age,intravenous administration and antibiotics use are important ones. Great importance should be attached to rational clinical drug use as well as ADR/ADE monitoring and re-porting. Clinical also should pay attention to the safety of drug use in elderly patients.

Objective To evaluate the value of multi-slice spiral computed tomography (MSCT) in diagnosing postoperative intestinal obstruction of rectal cancer.Methods The CT imaging results and clinical manifestation of 50 patients with postoperative intestinal obstruction of rectal cancer confirmed by pathology were reviewed retrospectively.These cases including Miles (24 cases),Dixon (18 cases),Hartmann(8 cases) procedure were collected from Tianjin People's Hospital from 2011 to 2013.Conservative management was done in 10 cases and the remaining 40 patient underwent surgical intervention.Statistical difference between the three kinds of surgical causes of intestinal obstruction was analysed by x2 test.Results Most common cause after Miles and Hartmann postoperative intestinal obstruction was of adhesion,while anastomotic stenosis was the most common reason of intestinal obstruction after Dixon procedure.The difference of incidence of intestinal obstruction caused by hernia and anastomotic stenosis between the three kinds of operation method was statistically significant (x2 =5.382、20.486,P ＜ 0.05).Conclusions MSCT could identify the etiology and site of postoperative intestinal obstruction of rectal cancer,providing favorable imaging evidence for clinical treatment.

Objective To study the biological characteristics of cypermethrin?resistance strain and?susceptible strain of Ae?des albopictus under different controlled temperatures in the laboratory. Methods The two strains were raised at three different temperatures 20 25℃and 28℃respectively and the biological characteristics of the two mosquito strains such as reproduc?tion development and life expectancy were observed and recorded in the laboratory. Results The life expectancy of both strains became shorter as the temperature raised and the resistant strain 69.37%± 0.01% 77.04%± 0.07% lived shorter than the susceptible strain 85.24%±0.03% 88.23%±0.05% in average. Under 25℃ the hatching rate of resistant strain decreased by 25.88% and the pupation rate decreased by 11.18%. In the three temperatures all the life expectancy expanded as the tem?perature went up the periods for the susceptible strain were 19.75±0.10 23.65±0.07 d and 25.08±0.08 d under 28 25℃and 20℃. While life expectancy for the resistant strain decreased to 17.21±0.09 20.95±0.09 22.58±0.10 d. Under the same tem?perature the development timing of the resistance strain was longer than that of the susceptible strain and the period was the longest under 28 ℃ 156.2 h 137.1 h . In the three temperatures all the development periods expanded as the temperature went up the susceptible and resistant larvae developed 137.1 d and 163.3 d 247.7 d and 156.2 d 182.3 d and 263.2 d under 28 25℃and 20℃. The differences show statistic significance P<0.05 . Conclusion The resistance of A. albopictus to cy?permethrin results in the decrease of adaptability to the environment change and the disadvantage of reproduction at different temperatures.

Objective: To evaluate the dietary exposure to deoxynivalenol (DON) from cereals and health risk in Chinese residents in different regions. Methods: The data of DON concentration in cereals was derived from the national food safety risk surveillance from 2010 to 2017, with 15 422 samples of cereals included. China was roughly divided into north part and south part, along with the Qinling Mountains-Huaihe River line. Sample size of each type of cereals, i.e. wheat flour, maize meal, oats and rice was 4 948, 696, 626, 1 006 in the north, while 5 648, 1 068, 266, 1 164 in the south. The data of cereals consumption was derived from China National Nutrition and Health Survey in 2002 and 68 335 respondents aged 3 and above, with 34 234 from the north and 34 101 from the south, were included. Simple distribution model was applied for calculation and comparison of the dietary exposure to DON from cereals in northern and southern residents based on individual consumption of cereals, body weight and average DON concentration in each type of cereals. Results: Average DON concentration in wheat flour, maize meal, oats, and rice sampled in northern China were 235.4, 121.6, 7.0 and 4.6 μg/kg, respectively, while 239.1, 124.3, 29.0 and 15.5 μg/kg in cereals sampled in southern China. The average DON exposure from cereals in surveyed Chinese inhabitants was 0.78 μg/(kg·d). Among them, the DON exposure of northern residents was higher than that of southern residents (P<0.001), and the average exposures were 1.15 and 0.41 μg/(kg·d), respectively. A total of 49.2% of northern residents exceeded provisional maximum tolerable daily intake for DON exposure from cereals, which was much higher than that of southern residents (8.6%) (P<0.001). Wheat-based food products were the main source of DON exposure, with a contribution rate of 96.5% in the north and 68.3% in the south. Average DON exposure was the highest in the 3-6 years [2.12 μg/(kg·d) for children in north and 0.73 μg/(kg·d) in south]. Conclusion Exposure to DON from cereals in northern residents of China was considerably high, with a certain health risk. Northern children aged 3 to 6 exposed even more DON and needed significant attention.

Objective: To investigate the aluminium content in unprocessed grains from different areas of China. Methods: From June 2013 to December 2014, nine provinces (Jilin, Shandong, Hubei, Hunan, Guangdong, Guangxi, Henan, Anhui and Jiangsu) were selected as sampling areas using stratified random sampling method. Three cities, counties or townships were randomly selected from each sampling area. Grain stations, grain depots, planting areas or farmers′ markets located in non-aluminium mining areas or non-aluminium-involved industrial pollution areas were selected from each sampling area using a purposive sampling method. A total of 470 unprocessed grain samples (500 g per sample) including wheat, rice, corn, millet and soybean were collected from local grain stations, grain depots, planting areas and farmers′ markets. The dried grains samples were analysed for aluminium content by inductively coupled plasma mass spectrometry. Bootstrap resampling method was applied to calculate the upper bound values of 95%CI of P₉₉ of aluminium contents for each kind of grain, which could be regarded as levels of concern for corresponding categories. Results: A total of 454 grain samples, including 109 wheat samples, 111 rice samples, 78 corn samples, 69 millet samples and 87 soybean samples, were used for analysis after excluding outlier values. There were 420 positive samples with detected aluminium and the overall detection rate was 92.5%. Among them, the aluminium contents were high in wheat and soybean with median values about 9.59 and 7.12 mg/kg, and maximum values about 31.55 and 28.80 mg/kg, respectively. The median and maximum values of aluminium contents in corn were about 4.65 and 26.79 mg/kg. Aluminium contents were low in rice and millet, with median values about 1.49 and 2.21 mg/kg, and maximum values about 7.56 and 8.07 mg/kg, respectively. Based on Bootstrap resampling method, the upper bound values of 95%CI of P₉₉ of aluminium contents in wheat, soybean, corn, rice and millet were 29.86, 28.80, 26.79, 7.56 and 8.07 mg/kg, respectively, which could be regarded as levels of concern for corresponding grains. Conclusion Aluminium has been detected in most unprocessed grains. The accumulation of aluminium varies in different grains species.

Infection is one of the most common causes of death in patients with multiple myeloma, which can lead to early death. The incidence of infection in patients with (multiple myeloma, MM) complicated with diabetes is further increased. Proteasome inhibitors, immunomodulatory drugs and other new drug therapy improve the prognosis of MM, but glucocorticoids used in combination chemotherapy are easy to induce glucocorticoid diabetes, lead to elevated blood glucose, increase the risk of MM infection, and affect the prognosis of patients. This article reviews the relationship between infection and disease progression in patients with MM complicated with diabetes mellitus, infection-related factors, and prevention and treatment measures of different types of pathogen infection.

[ ABSTRACT] AIM:To investigate the depressant effect of FK228 combined with rapamycin on the human breast cancer cell line MCF-7 and MDA-MB-435.METHODS:FK228, a new histone deacetylase inhibitor, and rapamycin, the specific inhibitor of the mammalian target of rapamycin ( mTOR) protein, were used in the study.MCF-7 cells and MDA-MB-435 cells were exposed to different concentrations of FK228 and rapamycin.The inhibitory rate of cell growth was de-termined by SRB assay.Combination index ( CI) was used to evaluate the interaction between FK228 and rapamycin.The expression of the apoptotic proteins, cycle proteins and nucleic acid proteins were detected by Western blotting.The cell cycle was analyzed by flow cytometry.RESULTS: Both FK228 and rapamycin showed growth inhibitory effects on the breast cancer cell lines in a time-and dose-dependent manner.CI of the 2 drugs was less than 1 when the inhibitory rate of the cell growth was 50%effective dose (ED50)~ED70, indicating a synergistic effect.The combination therapy of FK228 with rapamycin increased the apoptotic proteins, and induced the down-regulation of phosphorylated Akt and over-expres-sion of caspase-3 compared with a single use of the drugs.The combination therapy of FK228 with rapamycin reduced the cycle proteins, and the cell cycle was arrested in G2/M.The levels of phosphorylated H2AX and acetylated H3 were ob-viously increased after combination therapy.CONCLUSION:The combination therapy of FK228 with rapamycin inhibits the cell proliferation and increases apoptosis with a synergistic effect, which may become a new trend for treating endometri-al cancer.

Objective:To study the effect of Helicobacter pylori (HP) infection on the standardized dose of postoperative thyrotropin suppression of differentiated thyroid carcinoma.Methods:A total of 82 patients diagnosed with differentiated thyroid carcinoma and receiving total thyroidectomy in Beijing Rehabilitation Hospital affiliated to Capital Medical University from Jan. 2019 to Jun. 2020 were enrolled in this study prospectively.19 patients with higher standardized dose of the thyrotropin suppression (>2.5 μg·kg -1·d -1) were selected as the experimental group, and 63 patients with the lower standardized dose of the thyrotropin suppression (≤2.5 μg·kg -1·d -1) were selected as the control group. The presence of HP infection was measured by C13 method, and the HP infection rate was compared between the two groups. The patients with HP infection in the experimental group received standard quadruple therapy to eradicate Helicobacter pylori. The standardized dose before and after treatment were observed and compared. Results:The HP infection rate in the experimental group (73.7%, 14/19) were significantly higher ( P<0.05) than those in the control group (31.7%, 20/63). In the experimental group, 14 patients with HP infection in the experimental group received standard quadruple therapy to eradicate HP. HP was successfully eradicated in 11 patients after the treatment (one patient quit the treatment before completion, the actual eradication rate was 84.6%) ; Eight weeks after the treatment, the dose adjustment of thyrotropin suppression reached steady-state in 13 patients completed the therapy. The average standardized dose was (2.15±0.25) μg·kg -1·d -1, significantly lower than that before treatment [ (2.89±0.21) μg·kg -1·d -1] ( P<0.05) . Conclusions:HP infection may be an important factor affecting the standardized dose of thyrotropin suppression in postoperative patients with thyroid cancer. For those patients with HP infection, eradication treatment of HP can significantly reduce the standardized dose and treatment-related complications.
