Objective To discuss the effect of Chinese medicine treatment on quality of life(QOL)of perimenopause syndrome(PMS)patients.Methods The evaluation with WHO QOL-BREF in Chinese version was applied to compare the QOL scores of normal perimenopause females with those of PMS patients.Results The scores of normal perimenopause group were higher than those of PMS group and the difference of scores of all aspects was significant(P

Objective To determine the effect of reducing mA on the diagnostic quality of images and the radiation dose to the lens in patients undergoing paranasal sinus CT. Methods Fifty patients undergoing paranasal sinus CT at 200 mA or 50 mA. The lens dose was measured using thermoluminescent dosemeters [LiF(Mg?Cu?P)]. Image quality was evaluated for six anatomical structures, including middle turbinate, uncinate process, maxillary ostium, ethmoid infundibulum, frontal recess, and cribriform plate. These anatomical structures were assessed as: not seen (0 points), demonstrated but not clearly visualized (1 points), or clearly demonstrated (2 points). Results Mean radiation dose to the lens was significantly reduced from 7.339 mGy (200 mA) to 1.108 mGy (50 mA). No significant difference of image quality between the two mA protocols was found in either rhinosinusitis group or non-rhinosinusitis group. And for rhinosinusitis the image quality showed no significant difference between high-resolution arithmetic and soft arithmetic. Conclusion CT scanning of the sinuses can be performed at greatly reduced mA without loss of diagnostic quality of the images. As far as the rhinosinusitis is concerned, high-resolution arithmetic can not improve the image quality and soft arithmetic is enough.

Background C57BL/6.NOD-Aec1Aec2 mouse is considered to be an idea model for the study of the pathogenesis of Sj(o)gren syndrome,but the cause of dry eye in these mice is unclear.Objective This study was to investigate the histopathological change of the ocular surfaces of C57BL/6.NOD-Aec1Aec2 mice,and to determine whether dry eye is developed spontaneously in these mice.Methods Forty-five clean C57BL/6.NOD-Aec1 Aec2 mice were used as the experiment group and forty-five C57BL/6J mice(both male and female)were used as the control group in this study.Detection of fasting blood-glucose,Schirmer' s test Ⅰ (S Ⅰ t),lissamine green staining and scoring of the corneal and conjunctival epithelium in the mice were performed at the age of 4,8,12,16 and 20weeks.Five mice from each group were sacrificed and their corneas were obtained to measure the central corneal epithelium thickness and to count the number of conjunctival goblet cells.In addition,lymphocyte infiltration in the lacrimal gland of the mice was examined with hematoxylin-eosin staining.The uhrastructure of the corneal epithelial cells and microvilli were assessed by scanning electron microscopy.The use and care of the mice were approved by the Experimental Animal Care Committee of the Third Military Medical University.Results No sign of dry eye was seen in both the 4-week-old C57BL/6.NOD-Aec1Aec2 mice and 4-week-old C57BL/6J mice.The S Ⅰ t values in 8-week-old,12-week-old,16-week-old and 20 week-old mice from the experiment group were (2.7 ±0.9) mm,(2.5 ±0.8) mm,(1.8±0.6) mm and (1.9± 0.1) mm,respectively,showing a significant reduction in comparison with those of the control mice of the same age(all P＜0.01).The amount of lissamine green staining in the C57BL/6.NOD-Aec1Aec2 mice gradually increased with age,showing elevated scores in 12-week-old,16-week-old and 20-week-old mice in the experiment group(all P＜0.01).The central corneal epithelium thicknesses were(20.18±3.75)μm,(17.01 ±5.25) μm,(14.19±5.72) μm and(12.00±3.25) μm in the 8-week-old,12-week-old,16-week-old and 20-week-old C57BL/6.NOD-Aec1Aec2 mice,respectively,which were significantly lower than those of the C57BL/6Jmice of the same age (all P＜0.01).The numbers of conjunctival goblet cells were (8.2±2.4),(6.2±2.1),(6.1 ±2.2) and (4.1 ± 2.0) in the 8-week-old,12-week-old,16-week-old and 20-week-old C57 BL/6.NOD-Aec 1Aec2 mice,respectively,showing a gradual decrease with age and a significant decline in comparison with those of the C57BL/6Jmice of the same age(all P＜0.01).Lymphocyte infiltration in the lacrimal gland and destruction of gland ducts were seen by hematoxylin-eosin staining,and acinar abnormality aggravated with aging.Reduction of corneal epithelial cells and the number of microvilli were distinguished with aging under the scanning electron microscope.The fasting bloodglucose levels of the two groups were both less than 6.0 mmol/L,and no significant difference was found between them at any age(P=0.637,0.610,0.163,0.086,0.938).Conclusions C57BL/6.NOD-Aec1Aec2 mice develop dry eye spontaneously with aging.The course of disease and characteristics of dry eye in C57BL/6.NOD-Aec1Aec2mice is similar to human dry eye.The C57BL/6NOD-Aec1 Aec2 mouse is the perfect model to study the pathogenesis of dry eye.

Objective: To investigate recombinant human insulin-like growth factor-1 (rhIGF-1) on the phosphorylated serine-threonine protein kinase (pAkt) and apoptotic cells in edematous perihematomal brain regions following experimental intracerebral hemorrhage in rats. Methods: A total of 78 healthy male rats were randomly assigned to a false operation group (n =6), a cerebral hemorrhage control group (control group for short, n=36) and a rhIGF-1 intervention group (intervention group for short, n=36). According to 6 time points after giving intervention measures, the rats of the control and intervention groups were randomly redivided into 6 subgroups: 6 h, 12 h, 1 d, 2 d, 4 d, and 7 d subgroups (n =6 in each subgroup). A rat model of acute cerebral hemorrhage was induced by stereotaxic injection of collagenase type IV. RhIGF-1 (50 μg/kg) was injected via tail veins in the intervention group, once a day, until the end of the experiment. An equivalent isotonic saline was injected via tail veins each day in the sham operation and control groups. Samples were taken from each group at a specified time. An immunohistochemical method was used to observe the expression of pAkt around hematomas ; deoxynucleotidyl transferase-mediated terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) technique was used to observe apoptotic cells. Results: Circled digit oneThe neurological deficit score of the rats in the control group and intervention group reached the highest at day 1 or day 2 after procedure, then decreased gradually. The only score in the intervention group at day 7 after procedure was lower than that in the control group. The difference was statistically significant (P <0. 05). Circled digit twoThere were only a few expressions of pAkt positive cells in rats of the false operation group. Except the 6-hour time point, the numbers of pAkt positive cells at the remaining time points in the intervention group were higher than those in the control group. The difference was statistically significant (P < 0. 05). Circled digit threeOnly a few TUNEL positive cells were observed in the false operation group. Except the 6-hour time point, the numbers of TUNEL positive cells at the remaining time points in the intervention group were significantly lower than those in the control group. The difference was statistically significant (P < 0. 05). Conclusion: RhIGF-1 may reduce apoptosis after cerebral hemorrhage and improve the neurological function. Its role may be associated with the activation of pAkt.

Objective:To investigate the knowledge, attitudes and practice of child sexual abuse (CSA) prevention education in parents of elementary school pupils.Method:Two hundred and seventy one parents were surveyed by anonymous self-administered questionnaire in five classes of grade 1 to grade 5 of a elementary school. The questions about awareness of CSA and communications on how to prevent CSA with their children were asked.Result:Among this sample, 93.6% of parents approved of school CSA prevention education. Overall, about half parents lack of knowledge of CSA prevention, the communications with their children were also not enough. Only 1.8% of parents had provided books or audiovisuals about CSA prevention for their children. The scores of knowledge, attitudes and practice of CSA prevention education of parents whose parents addressed this in their childhood were significantly higher than those of parents who had no this experience.Conclusions:The research of CSA prevention education in elementary school should be paid more attention, to produce related books and audiovisuals as soon as possible, to increase parents' awareness of CSA prevention.
