· AIM: To explore the relationship between the expression of Fas/FasL and the apoptosis in retinal ischemia/reperfusion injury of rats, as well as the therapeutic effects of basic fibroblast growth factor (bFGF)on the ischemic retina.injury were made by transiently elevating introcular pressure. A total of 28 rats were divided into Normal Group and Operative Group. The latter were subdivided into 1, 6, 12, 24, 48 and 72h after reperfusion, in which the left eyes of the rats were in the ischemia/reperfusion groups and the right ones were in the treatment groups (bFGF intracameral injection). Apoptosis was assessed by the terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick-end labelling (TUNEL) method, and theexpression of Fas/FasL ligand was studied by strept avidin-biotin complex (SABC) immunohistochemistry.mai rats' retinae, but there were a significant number of TUNEL positive cells in 6-24h after transient ischemia followed by a decrease at 48h. The number of TUNEL positive cells reached a maximum at 24h after ischemia.The expression of Fas gradually increased as early as at 6h, reached a peak at 24h, then decreased at 48h. Similarly, the expression of Fas ligand was at peak in 24-48h in GCL and INL of retina. bFGF ministered before reperfusion inhibited apoptotsis and ameliorated the tissue damage. It also diminished Fas and FasL expression in ischemic/reperfused retina.siently elevated IOP induced apoptosis of cells in the retina. Fas/FasL may have an important role in the early events of the apoptotic pathways. bFGF can rescue RGCs from retinal ischemia/reperfusion injury through down-regulation of Fas and Fas ligand expression and may represent an important mechanism for therapeutic neuroprotection.

Developmental changes in children can affect drug disposition and clinical effects. A physiologically-based pharmacokinetic (PBPK) model is a mathematical model that can be used to predict blood drug concentrations in children and gain insight into age-dependent physiological differences in drug disposition impact. Pediatric PBPK (P-PBPK) models have attracted attention over the past decade. With the concerted efforts of academia, pharmaceutical companies, and regulatory agencies, there are more and more examples of pediatric clinical studies using PBPK models. Nevertheless, the number of P-PBPK models and their predictive performance still lag behind adult models. By referring to the literature, we study the process of children adapting to adult absorption, distribution, metabolism, and excretion (ADME) parameters and analyze the general principles of P-PBPK model establishment. In addition, we summarize the functions and application examples of commonly used P-PBPK modeling software to provide a basis for the rational application of modeling software.

Objective: To evaluate the knowledge, attitude and behavior on blood lipid among people in Changsha and to provide evidences for prevention and control of blood lipid abnormality. Methods: A total of 400 cases were randomly selected on the questionnaire of the knowledge, attitude and behavior on blood lipid in ordinary adults who participate in health examination in Xiangya Hospital. Blood lipid related physical examination was conducted at the same time. hTe health examination participants were divided into several groups according to their sex, age, degree of education, marriage and family income. The influential factors for knowledge, attitude and behavior were analyzed. Results: hTe knowledge score of blood lipid for health examination participants was 18.33±8.67 (total score 37), the attitude score was 6.63±2.45 (total score 9) and the behavior score was 8.32±2.65 (total score 16). hTe scores of female was higher than that of male in the terms of knowledge and behavior (bothP<0.05); the scores in the 40–49 age group were lower than those in the other age groups (all P<0.05); the scores in the junior high school group were lower than those in the other education groups (allP<0.05); the scores in the family group with less than 2 000 yuan income were lower than those in other family groups with different income (allP<0.05). The multiple stepwise regression analysis showed that: 1) the knowledge on blood lipid score was inlfuenced by ages and education background (bothP<0.05); 2) while the attitude of blood lipid was inlfuenced by four factors such as education background, systemic blood pressure, blood sugar and triglyceride(allP<0.05); 3) the behavior on blood lipid was inlfuenced by ifve factors such education background, triglyceride, systemic blood pressure, blood sugar and ages (allP<0.05). Conclusion: The knowledge, attitude and behavior on blood lipid among health examination participants were mostly influenced by education background, gender and ages. Thus, clinical medical staff should prevent the blood lipid abnormality through the health education and improve the knowledge in normal people. hTe group of 40–49 age male should be thought as the primary intervention subjects. hTe knowledge, attitude and behavior on blood lipid among the general population is also related to individual’s blood pressure, blood sugar and triglyceride. So the clinical medical staff should also improve the knowledge of blood lipid, blood pressure and blood sugar in general population for improving their attitude and unhealthy habits. In addition, the active control of blood sugar and blood pressure can enhance the overall health status of the general population.

Objective To study the efficacy of rituximab in the treatment of pemphigus vulgaris (PV) and its underlying mechanism. Methods A 38-year-old female with PV presented with refractory, painful oral ulcers and erosions. Since she was poorly responsive to prednisone 80 mg daily, intravenous ritu-ximab of 500 mg once a week was given for successive 3 weeks followed by 5 successive days of intra-venous gamma globulin at a dose of 400 mg/kg per day, and a total of two treatment sessions were conducted. ELISA was used to detect the serum titer of anti-Dsg3 antibodies and their IgG subtypes (IgG1 and IgG4) as well as serum level of interferon-gamma (IFN-gamma), interleukin-4 (IL-4), interleukin-10 (IL-10). Results Three months after the end of two treatment sessions, the symptom was obviously improved, and lesions subsided; alter another 1 month, clinical symptom fully disappeared. During the 1-year follow-up, no lesions recurred. The anti-Dsg3 antibody titer was 253.33 U/mL before treatment, plateaued at 250 U/mL within 4 weeks after the initial infusion, decreased till 3 months after the withdrawal, and reached 26.06 U/mL 7 months after the withdrawal, and remained within normal range till the time of this writing. The serum titer of IgGl subclass of anti-Dsg3 antibodies dropped dramatically fight after the first infusion, but that of IgG4 subclass remained at a high level at early stage of medication, began to decline until 3 months after the with-drawal, and finally reached the normal range following clinical remission. Also, serum level of IFN-garnma and IL-10 correlated with the severity of PV. Conclusions Combined rituximab is effective for the control of PV, likely by eliminating Dsg3-specific antibodies, especially IgG4 subclass of them.

ObjectiveTo summarize the clinical significance of ultrasonic screening of fetal structural anomalies at 11-13+6 weeks.Methods We conducted a retrospective study of 4853 cases of nuchal translucency screening at 11-13+6 weeks in Maternal and Child Health Hospital of Bao?an of Shenzhen City from September 2011 to May 2014. The screening ultrasound planes included the median sagittal plane, neck sagittal section, cerebral transverse section, cardiac four-chamber view, three-vessel-trachea view, abdominal transverse section, bladder section, upper limb section and lower limb section of the fetuses. All the cases then underwent the ultrasonic structural screening in the second trimester (20-24 weeks) and the third (28-32 weeks) trimester and were followed up until 6 weeks after birth or the biopsy after abortion.Results Eighty-ifve fetal structural anomalies were detected among the 4853 pregnant women at 11-13+6 weeks of gestation with the detection rate of 1.75% (85/4853), including central nervous system abnormalities (28 cases), anterior abdominal wall anomalies (9 cases), cardiac anomalies (6 cases), urinary system malformation (3 cases), skeletal system malformation (2 cases), multilocular cystic tumor and dropsy embryo (35 cases), and abnormal twins (2 cases). Among above abnormal fetuses, 6 cases showed normal structure in the screening after 14 weeks and were born without malformations, while the rest 79 cases were taken artiifcial abortion (73 cases in the ifrst trimester and 6 cases in the second trimester). Only 9 cases were taken chorionic puncture or amniocentesis, including normal karyotypes (3 cases), 47, XN, +18 (3 cases) and 45, X (3 cases). The False negative rate in the ifrst trimester was 23% (25/110). Supplementary detection of fetal structural abnormalities in the second and third trimester were found in 22 cases (20%, 22/110). Two cases of VSD and 1 case of microtia were identiifed after birth.ConclusionsThe fetal malformation can be detected in the earlier gestation with the ultrasonic screening at 11-13+6 weeks, which provide the earlier termination to the abnormal fetus. It has important clinical signiifcance in effectively reducing fetal births with structural abnormalities.
