Objective To investigate the symptoms of diarrhea and the behavior of medical treatment after diarrhea in 2013 in Tianjin City, and provid background information for the future population monitoring. Methods A stratified sam?pling method was used to investigate the symptoms, medical treatment and self medication behavior of 4028 residents in Tianjin. Results The number of people who had diarrhea in 2013 was 324, and the incidence rate of diarrhea was 8.04%. Diarrhea was mainly occurred in May-October (n=241, 74.38%). The incidence of diarrhea was the highest in 60-74 years old group, followed by 75-years old and 0-14 years old groups. The incidence of diarrhea was the lowest in 15-29 years old grouop. A total of 121 patients with diarrhea chose to go to hospital (47.08%), 78 patients chose to buy medicine for treat?ment (30.35%) and 58 patients did not do any disposal (22.57%). Among the patients with diarrhea, the highest proportion of patients chose to go to the first grade and the following medical institutions (68.59%, 83/121). There were 14.05%(17/121) and 17.36%(21/121) patients chose to go to the second and the third levels of medical institutions for the treatment. The av?erage cost for patients with diarrhea was 60 (20, 200) yuan. The purchasing expenditure median was 20 (11,50) yuan. The medical spending was more than the purchase of medicines (Z=2.412, P<0.05). The average cost of medical treatment was more higher in the second and the third levels of medical institutions than that of the first medical institution ( Z=50.709,P<0.05). The average cost of medical treatment was in turn increased for patients with diarrhea treated in Baodi county, Xiqing county, Hangu county and Heping county (Z=74.282,P<0.05). There was no statistical significance in medical expenses be?tween patients with different ages and patient with or without medical insurance. Conclusion There are high incidence of diarrhea in patients under 15 years old and patients over 60 years old. Residents suffering from diarrhea mainly choose their own medicine and the treatment in the first and following medical institutions.

In this paper, further study was made on the teratogenicity and the morphological teratogenesis mechanism of neural tube defects (NTD) caused by cyclophosphamide(CP). Pregnant SD rats were given single intraperitoneal injection of CP 15 mg/kg on day 13 of gestation. The fetuses were removed on day 20 of gestation, weighed and examined for external malformations. Some embryos were removed respectively at 4, 8, 12, 24, 48 hr after administration of CP, and examined with light microscope and electron microscope. The results showed that CP has obvious embryotoxie and teratogenic effects. Of the survivings, 97.46％ showed external malformations including encephalocele, exencephaly, opened eyes, micrognathia, limb and digital defects etc. We considered that the possible way by which CP caused the malformation on developing embryos may involve the following aspects: (1) CP caused DNA-synthesising cells to degenerate and become necrosis. (2) The cellular organelle (mitochondria and endoplasmic reticulum, etc.) became irregular in shape and fragmented. (3) The mesenchyme surrounding the neural tube were also damaged by CP and therefore influenced the skull ossification.

[Abstract ] Objective Globular C1q receptor (gC1qR), a highly acidic receptor protein, is expressed in almost all mamma-lian cells in addition to exoerythrocytic, which can mediate a variety of biological responses.The study aimed to explore gC1qR expres-sion in cervical cancer and itd effects on the biological behaviors of human cervical cancer cells. Methods Retrospective analysis was made on 100 cervical tissue samples of patients in Nanjing Maternal and Child Health Hospital from August 2014 to April 2015, in-cluding 50 cervicitis tissues and 50 cervical cancer tissues.Immunohistochemical SP method was applied in the research of cervical cancer cell line C33a to detect the expression and the location of gC1qR in cervical tissues.Real-time PCR and Western blot analysis were respectively applied to detect the levels of gC1qR mRNA and gC1qR protein expression.Besides, the abilities of C33a cells mi-gration, invasion and apoptosis were respectively assessed by in vitro cell wound healing experiment, transwell assay and flow cytome-try. Results The expression of gC1qR gene was dramatically decreased in the group of cervical cancer tissues when compared with chronic cervictis group (2.18 ±0.37 vs 7.23 ±0.69, 0.27 ±0.09 vs 0.74 ±0.02, P<0.001).gC1qR overexpression could result in sig-nificant up-regulation of cervical celluer apoptosis([22.89 ±1.46]%vs [12.98 ±0.57]%) and down-regulation in migration ([42.60 ± 3.29]%vs [141.83 ±4.71]%) and invasion([26.20 ±2.89]%vs [67.13 ±0.95]%).Typical apoptosis was also observed in cervi-
cal cells by transmission electron microscope. Conclusion gC1qR expression might play an important role in inhibiting the invasion and migration of cervical cancer cells and inducing the apoptosis of cervical carcinoma cells, which provides new clues and potential targets for the treatment of cervical cancer in further research.

In order to evaluate the overall situation of projects granted by National Natural Science Foundation of China (NSFC) in the 11th five-year plan period,the data about applications and approved NSFC projects at Cancer Institute and Hospital of Chinese Academy of Medical Sciences (CIH CAMS) were analyzed and compared with those of the 10th five-year plan period.It showed that the number of granted NSFC projects increased and the structure of program type maintained during the 11th five-year plan period.The program researchers were younger and had better education background.The quality and quantity of both the General Program projects and Young Scientists Fund projects were at high level.

Objective To evaluate correlations between left atrial(LA) and left ventricular(LV) function in patients with hypertension by acoustic quantification(AQ) technique. Methods Forty-eight hypertensive patients and twenty control subjects were studied. Patients with hypertension were divided into two groups by left ventricular mass index(LVMI),normal LVMI group(32 cases) and left ventricular hypertrophy(LVH) group(16 cases). Left atrial ejection fraction(LAEF),atrial emptying volume(AE),conduit volume(CV) and reservoir volume(RV) were measured with AQ technique. Results RV and AE significantly increased in normal LVMI subgroup and LVH subgroup;CV and LAEF respectively decreased or increased in LVH subgroup. LA booster pump function positively correlated to onset atrial emptying volume and RV,negatively correlate to CV and LV diastolic function. LA conduit function positively correlated to LV diastolic function,negatively correlated to LAEF and AE,RV as well as onset atrial emptying volume. LA reservoir function positively correlated to onset atrial emptying volume and LAEF,negatively correlated to CV. There was no significant correlation between LA reservoir function and LV diastolic function. Conclusions LV diastolic dysfunction induces decreased LA conduit function and increased reservoir function,which may facilitate early diastolic filling of the left ventricle. The changes of LA conduit function and reservoir function may increase of LA preload. Enhancement of LA preload and LA systole makes increased LA booster pump function,which facilitate late diastolic filling of left ventricle.

Objective: To investigate health equity status of the elderly with different socioeconomic status(SES)and provide basis for health promotion. Methods:The data of 2011-2012 China Health and Retirement Longitudinal Survey was used to analyze health equity of the elderly with different SES. Results: There is an inverse socioeconomic gradient in self-evaluation of ill health and the prevalence of activity of daily living (ADL). The lower economic level is, the higher self-evaluation of ill health and the damage rate of ADL are, and the higher non-outpatient rate and non-hospitalization rate are; the urban elderly have better health and use more health services and the elderly in eastern region have better health and use more health services than those in eastern region. Conclusion: There is the health inequity for the elderly with different SES. In order to implement the health care insurance and medical assistance system of the elderly, it needs to allocate health resources to rural and western areas, narrow the gap between urban and rural areas and improve the health level of the elderly.

篈 new diterpene,rabdonervosin A(I ) was isolated from an ethanolic extract of the leaves and stems ofRabdosia nervosa co1lected in Jiangxi,China. Its structure was established as 1Q, 69, 15Attihydroxy-6, 7-B-sec-oent-kaur-16-en-6, 20-epoxy-7, 20-8-olide on basis of spectroscopic data.

Objective To evaluate the application of tendency-oriented perimetry (TOP) in detecting the visual function of glaucoma. Methods The traditional threshold perimetry (Normal/Normal strategy) and TOP (TOP/Normal strategy) carried out by Octopus 101 perimetry were used to examine the visual field of 20 normal subjects (20 eyes), 32 cases (32 eyes) of primary open-angle glaucoma (POAG), and 14 cases (14 eyes) of suspected POAG, respectively. The visual field outcomes, indices, point by point threshold variability and defective points of the two perimetries were compared and analysed. Results The negative rate of TOP was 90% in normal subjects. The positive rate of TOP was 75% in POAG , and 100% in middle and late stage of POAG. The visual field indices of two perimetries were positively correlated, with mean sensitivity (MS) of r=0.9335, mean defect (MD) of r=0.9189, and loss variance (LV) of r=0.9621. The point by point threshold variability and defective points of TOP were higher than those of traditional threshold perimetry, but the difference between the two perimetries was not significant (P=0.2019, P=0.4448). Conclusion The visual field indices of TOP and traditional threshold perimetry are positively correlated. The sensitivity and reproducibility of TOP are high in detecting the visual function of middle and late stage of POAG.
