Study on the relationship between blood concentration and efficacy of voriconazole in the treatment of pediatric invasive fungal infection / 药学实践杂志

Objective To explore the correlation between dose, blood concentration and efficacy of voriconazole in the treatment of invasive fungal infection in children. Methods 68 children treated with voriconazole during January 2019 to December 2019 were collected. The plasma concentration of voriconazole was assayed by high performance liquid chromatography (HPLC). The correlation between blood concentration and clinical efficacy was statistically analyzed. Results Different drug blood concentrations were obtained with different dosages: <4.0 mg/kg (6 cases) with the trough concentration ranged from 0.4 to 3.31 μg/ml (r=0.613, P=0.195). (4.0 - 7.0) mg/kg (44 cases), ranged from 0.35 to 7.02 μg/ml (r=0.325, P=0.018); >7.0 mg/kg (18 cases), ranged from 1.46 to 12.45 μg/ml (r=0.584，P＜0.023). There was a difference between the three groups (F=7.270, P=0.026). The relationship between the drug blood concentration and the therapeutic effect was obvious. In the <1.0 μg/ml group of 14 cases, 10 cases (71.4%) were effective, and 4 cases were ineffective. In the 1.0 - 5.5 μg/ml group of 48 cases, 44 cases (91.7%) were effective, and 4 cases were ineffective. In the >5.5 μg/ml group of 6 cases, 4 cases (66.7%) were effective and 2 cases ineffective. The difference among the three groups was obvious (χ2=5.360, P=0.039). Among the 68 cases, 58 cases (85.3%) were effective, and 10 cases (14.7%) were ineffective. Adverse reactions occurred in 10 cases (14.7%) with mild liver function injury, which did not affect the treatment and recovered with liver protection treatment. Conclusion This study showed that voriconazole was generally safe and effective in the treatment of invasive fungal infections in children. There was a significant dose-blood concentration and efficacy correlation. Further studies on pharmacokinetics and efficacy should be carried out to optimize the individualized treatment.

Application value of chest CT angiography in active pulmonary tuberculosis complicated with pulmonary embolism / 国际生物医学工程杂志

Objective:To investigate the imaging characteristics of chest CT angiography in patients with active pulmonary tuberculosis complicated with pulmonary embolism, so as to improve the detection rate of active pulmonary tuberculosis complicated with pulmonary embolism.Methods:The clinical data of 103 patients with active pulmonary tuberculosis treated in Tianjin Haihe Hospital from January 2013 to January 2020 were retrospectively analyzed, including general conditions, symptoms and complications. According to the occurrence of pulmonary embolism, the patients were divided into active pulmonary tuberculosis complicated with pulmonary embolism group (study group, n=43) and active pulmonary tuberculosis without pulmonary embolism group (control group, n=60). The time between the onset of pulmonary embolism and the onset of tuberculosis of the patients in the study group was collected. The chest CT imaging characteristics of the patients of two groups were analyzed. The imaging characteristics, embolism distribution and secondary changes of the patients in the study group were summarized. Results:Time from onset of tuberculosis to pulmonary embolism of the patients in the study group was about 60 days (14 days to 75 days). The incidence of chest tightness and dyspnea of the patients in the study group was significantly higher than that in the control group (all P<0.05). The number of lung lobes involved in lung lesions of the patients in the study group was significantly higher than that in the control group ( P<0.05). The incidence of lesions in the middle lobe of the right lung, the tongue lobe of the left lung and the lower lobes of both lungs of the patients in the study group was higher than that in the control group (all P<0.05). The incidence of peripheral pulmonary embolism was significantly higher than that of central pulmonary embolism ( P<0.05). However, the incidence of atelectasis, pulmonary artery widening, and right heart enlargement in the patients with central pulmonary embolism was significantly higher than that in the patients with central pulmonary embolism (all P<0.05). Conclusions:Multi-slice spiral CT chest angiography can show some important imaging manifestations of patients with active pulmonary tuberculosis and pulmonary embolism, which is helpful for the early detection of the disease and the improvement of its prognosis. Multi slice spiral CT chest angiography can show some important imaging manifestations of patients with active pulmonary tuberculosis complicated with pulmonary embolism, and timely detection is helpful to improve the prognosis of patients with active pulmonary tuberculosis complicated with pulmonary embolism.

Preliminary study on estimating the energy and angle of incident protons based on the nuclear track morphology on CR-39 / 中华放射医学与防护杂志

Objective:To explore the method for estimating the energy and angle of incident protons based on the nuclear track morphology on CR-39.Methods:The CR-39 was irradiated with different energies and angles of incident protons and the morphology of nuclear tracks was scanned and read out by both the atomic force microscope and optical microscope after chemical etching. Through out quantitative analyses of the two-dimensional morphology of the nuclear tracks, an attempt was made to establish the method for estimating the energy and angle of incident particles.Results:As the increase of incident proton energy, the nuclear track became smaller and shallower. In the case of vertical incidence, the track opening was close to a circle. As the incident angle increases, the track opening gradually changed into an ellipse shape. The diameter of the circular nuclear track and the minor axis or the equivalent diameter of the elliptical nuclear track both decrease exponentially ( E= Ae - Bx) with the increase of the incident energy of protons. The fitting coefficients A and B were 15.763 and 0.305, and 15.886 and 0.320 by using the diameter/equivalent diameter and the minor axis of tracks. There also existed a relatively fixed quantitative relationship between the angle of the incident particle and the ratios of the major and minor axes of the elliptical nuclear track. For protons incident at 10° and 20°, the average ratios of the major and minor axes of the nuclear track were 1.10-1.15 and 1.35-1.37, respectively. Conclusions:Based on the diameter or minor axis of the nuclear track formed on CR-39, the energy of incident particles can be estimated, and the angle of incident particles can also be estimated by using the ratio of the major and minor axes of the nuclear track.

Fertilization of IVF/ICSI using sibling oocytes from couples with subfertile male or unexplained infertility / 华中科技大学学报（医学）（英德文版）

The significance of the performance of conventional in vitro fertilization and intracytoplasmic sperm injection (IVF/ICSI) using sibling oocytes from couples with subfertile male or unexplained infertility was evaluated. A total of 410 sibling oocyte cumulus-corona complexes (OCCC) from 21 couples with subfertile male (group A) and 11 unexplained infertile couples (group B) were randomly divided, in order of retrieval, into two groups inseminated either by conventional IVF or by ICSI. The treatment outcomes and the influence of infertility factors on fertilization in each group were compared. The results showed that although the two pronuclear (2PN) fertilization rate per injected sibling oocytes was significantly higher after ICSI (group A: 68.2% +/- 28.8%; group B: 66.2% +/- 24.9%) than after conventional IVF (group A: 41.8% +/- 32.7%; group B: 40.1% +/- 22.1%), the other variables studied included: the fertilization rates of per allocated sibling oocytes IVF/ICSI, the fertilization rates of sibling oocytes IVF/ICSI after excluding failed IVF fertilization cycles, as well as the cleavage rates of normal fertilization were not statistically significant (P>0.05). Similarly, though the total fertilization failure rate in the IVF group (group A: 42.9%; group B: 36.4%) was significantly higher than in the ICSI group (group A: 4.8%; group B: 0), we did not cancel cycles due to the normal fertilization of sibling oocytes. Embryo transfer was possible in all 32 couples. There were 10 clinical pregnancies in the two groups. We also discovered a possible association between some semen parameters and sperm functions of group A, and women age and duration of infertility of group B and fertilization. It is suggested that adoption of the split IVF/ICSI technology in the above cases may help eliminate fertilization failures. This is also a useful method to investigate the effect of single factor on the employment of assisted reproductive technology.

Background and Purpose:Prostate cancer is one of the most common cancers and the second leading cause of cancer-related death in Europan and North American males.The incidence of prostate cancer has also been increasing during the past few decades in China.It is widely accepted that this heterogeneity,which results from the tumor progression driven largely by genomic instability(genetic and/or epigenetic alterations)of tumor cells in primary tumor,endows specific populations of tumor cells with the unique character needed for invasion,migration,and metastasis colony formation in other organs and only these subpopulations possessing thost character can survive the potentially destructive journey from the primary tumor to the sites of metastases.The purpose of the present study was to explore the genes associated with invasion and metastasis of human prostate cancer cell line PC-3M in nude mice.Methods:After PC-3M cells were inoculated into orthotopic site(prostate) in a male nude mouse for two months,tumor cells were isolated from the primary tumor and lymph node metastasis,separately.Cell invasion and adhesion ability in vitro were first compared between two cells.Then metastasis-related genes differentially expressed between them were analyzed by utilizing cDNA microarray technique.Results:The in vitro cell invasion and adhesion potential of tumor cells from lymph node metastasis was significantly higher than those from primary tumor by 2.5 fold and 1.5 fold,respectively.Metastasis-related genes differentially expressed between those two sublines were identified,all of them were up-regulated in the tumor cells from lymph node metastasis and could be categorilized: 1.genes encoding cellular matrix-degrading proteolytic enzyme including cathepsin and MMP.2.genes encoding transcription factors.3.genes related to heterotypic adhesion of tumor cells.4.genes encoding cell surface receptors.Conclusions:There are significant differences in invasion and adhesion potential between cells from primary tumor and those from lymph node metastasis.Some differentially expressed molecules might be playing pivotal roles in promoting tumor cells to migrate from primary tumors to distant metastases,which may be helpful to elucidate the possible mechanism of metastasis in prostate cancer.
