A rare case of dicentric ring chromosome and derivative ring chromosome Chimera / 中华医学遗传学杂志

OBJECTIVE@#Utilize high-resolution chromosome analysis and microarray detection to determine the genetic etiology of infertility of a 32-year old female patient.@*METHODS@#The peripheral blood of the patient was cultured for high-resolution chromosome G and C banding karyotype analysis, and then 750K SNP-Array chip detection was performed.@*RESULTS@#Karyotype analysis results showed that the patient's karyotype was 45,XX,-13 [7]/46,XX,r(13) (p13q34) [185]/46,XX,dic r(13;13)(p13q34;p13q34) [14]/ 47,XX,+der(13;13;13;13) (p13q34;p13q34;p13q34; p13q34), dic r(13;13) [1]/ 46,XX [3]. The microarray results showed that the patient had a 3.3 Mb deletion in the 13q34 segment of chromosome 13, which may be related to infertility.@*CONCLUSION@#Infertility of the patient reported in this article may be related to the deletion of chromosome segment (13q34-qter).

Changes of the microcirculatory blood perfusion at "Feishu" (BL 13) in the COPD rats / 中国针灸

OBJECTIVE@#To observe the change of the specificity of the microcirculatory blood perfusion at the area of "Feishu" (BL 13) in the rats of chronic obstructive pulmonary disease (COPD).@*METHODS@#According to the random number table, 60 Wistar rats were divided into a 29 d model No. 1 group (C1 group), a 29 d normal control No.1 group (N1 group), a 89 d model No.2 group (C2 group) and a 89 d normal control No. 2 group (N2 group), 15 rats in each one. In the C1 and C2 groups, the smoking and intratracheal drops of endotoxin were used in combination to prepare COPD model. The rats were fed normally in the N1 and N2 groups. "Feishu" (BL 13), "Xinshu" (BL 15), the lateral site of "Feishu" (BL 13) and the lateral site of "Xinshu" (BL 15) were selected as the monitoring points. The pericam perfusion speckle imager (PeriCam PSI System) was adopted to monitor the microcirculatory perfusion unit (PU) at the monitoring points before and in 29 d and 89 d after modeling separately.@*RESULTS@#Before modeling, the differences in PU were not significant at each monitoring point in comparison among the 4 groups and the differences were not significant among "Feishu" (BL 13) and "Xinshu" (BL 15) as well as their lateral sites (all >0.05). After modeling, PU was increased at each monitoring point in the C1 and C2 groups (all <0.05). PU in the C1 group was higher than the N1 group and that in the C2 group was lower than the N2 group, PU at each monitoring point in the C1 group were higher than the C2 group, indicating the significant differences (all <0.05). In the C1 and C2 groups, the specific change occurred, in which PU at "Feishu" (BL 13) was higher than its lateral site. But such specific change did not happen in the N1 and N2 groups.@*CONCLUSION@#PU at "Feishu" (BL 13) presents the specific change relevant with the sickness duration in the COPD rats.

Adverse reactions in hematological system induced by antibacterial agents / 药学实践杂志

In recent years, with the wide use of antimicrobial agents, the adverse reactions related to antimicrobial agents have attracted more and more attention.Among them, the adverse reactions in hematological system induced by antibacterial agents seriously affect patient′s health and doctor′s selection for antibiotics.For example, some beta lactam antibiotics can cause dysfunction of coagulation and hemolytic anemia.Chloramphenicol and sulfonamides can cause aplastic anemia.Linezolid can cause thrombocytopenia and anemia.It is important to understand the adverse reactions in hematological system caused by antibiotics.In this paper, the antibiotic induced adverse reactions in hematological system and their mechanism were summarized in order to provide information for the rational use of antimicrobial agents.

Research advances in surgical treatment of intrahepatic bile duct stones / 临床肝胆病杂志

Although there are many surgical methods for intrahepatic bile duct stones, one single treatment cannot achieve the satisfactory therapeutic effect. The article introduces the progress in the etiology, pathological features, and therapeutic methods for intrahepatic bile duct stones. It is reckoned that combining various therapeutic methods according to the condition of disease is the key to reducing the rate of residual stones, preventing intrahepatic bile duct cancer, and achieving the optimal therapeutic effect.

Relationship of body mass index and blood lipid level with cancer detection on prostate biopsy / 天津医药

Objective To investigate the relationship between body mass index (BMI), blood lipid level and cancer de?tection in prostate biopsy. Methods A total of 214 patients undergoing a prostate biopsy during 2013.2—2014.8 were re?viewed retrospectively. They were divided into prostate cancer and non-cancer groups by biopsy results. The differences of age, prostate-specific antigen (PSA) level, prostate volume (PV), blood lipid level and BMI were analyzed between two groups. Risk factors for cancer detection of biopsy were also analyzed. Results Compared with non-cancer patients, pros?tate cancer patients were older, had higher level of PSA and BMI, but smaller PV and lower level of HDL-C ( P<0.05). Lo?gistic regression analysis showed that older, higher level of PSA and BMI were risk factors for prostate biopsy positive, but larger PV and higher level of HDL-C were protective factors (P<0.05). Conclusion Comprehensive assessment of BMI and blood lipid levels can provide important reference for prostate cancer screening at early time and establishment of pros?tate biopsy scheme, which also provide significant evidence for the prevention, diagnosis and treatment of prostate cancer at early stage for high risk population.
