ObjectiveTo survey 0—6 years old disabled children in Guiyang.Methods4 999 children aged 0—6 years old chosen randomly from 9 145 children of 12 blocks were investigated with the disability sampling survey criteria of 1987.ResultsThe rate of disabled children in Guiyang was 1.58%, and was not significantly different compared with that of whole country (1.36%) and other three areas including Siping City (P>0.05),but significantly higher than that of other six districts including Heping district of Tianjin municipality (P<0.05). All kinds of disability found by this survey were separately intellectual disability (0.92%),comprehensive disability (0.28%),limb disability (0.24%),vision disability (0.10%),psychiatric disability (0.03%),and hearing disability (0.02%). Rates of intellectual and vision disabilities were significantly higher than that of whole country ( P>0.05).ConclusionSome diseases are directly relative to occurrence of disability. The poor income of the children family,lower education of his parents and not gotten preschool education were risk factors of disability. The institution based rehabilitation and community based rehabilitation are main rehabilitation forms to disabled children.

To know the characteristics of Shuxuening injection used on cerebral infarction patients in clinical practice, 6 053 cases of Hospital information system (HIS) data from 20 hospitals were analyzed. Using the basic description method and association rules to analysis the data. By analysis the data we found that the average age of cerebral infarction patients who used Shuxuening injection is 67.96, 83.94% of patients were aged 46-80. The injection is administered intravenously,with most patients receiving a dosage of 15-20 mL per dose for between 1 and 14 days. It is always combined with aspirin (48.508%), cinepazide maleate injection (22.073%), atorvastatin calcium tablets (18.873%) in clinical practice. When it comes to two drug combinations, it always combined with cinepazide maleate injection and aspirin (8.178%), nicergoline capsules and aspirin (7.63%). Therefore, based on existing data, we give the conclusion that for the treatment of cerebral infarction Shuxuening injection is mainly used for older patients, and is often combination with similar pharmacological effects chemical drugs, which is complied with the guidelines. However, the wrong dose is still exist, doctors should realize the hiding risk.

Objective To investigate the effect of lung ischemic preconditioning (IP) on the expression of aquaporin-1 (AQP1) during lung ischemia-reperfusion (I/R) induced by cardiopulmonary bypass (CPB) in dogs.Methods Twelve adult mongrel dogs,weighing 15-20 kg,were randomly divided into 2 groups (n =6 each):lung I/R (group I/R) and ischemic preconditioning group (group IP).The left pulmonary artery was occluded at 10 min of off-pump CPB and mechanical ventilation was stopped in the left lung,60 min later occlusion was released,and mechanical ventilation was recovered to establish the model of left lung ischemia-reperfusion injury induced by CPB.In group IP,lung ischemic preconditioning was induced by 2 cycles of 5 min ischemia followed by 5 min reperfusion before occlusion of the left pulmonary artery.Before CPB (T1),immediately after occlusion of the left pulmonary artery (T2),at the end of CPB (T3),and at 2 h after the end of CPB (T4),pulmonary specimens were collected for determination of wet to dry lung weight ratio (W/D ratio) and expression of AQP1 and for examination of the pathological changes of lungs which were scored.Respiration index (RI),oxygenation index (OI),and alveolar-arterial oxygen tension difference (P(A-a)O2) were calculated at T1,T3 and T4,and the left pulmonary alveolar fluid clearance (AFC) was calculated at T4.Results Compared with group I/R,P(A-a) O2 and RI were significantly decreased,OI was increased,W/D ratio and pathological scores were decreased,the expression of AQP1 was up-regulated,and the AFC was increased at T3 and T4 in group IP.The pathological changes of the lung were significantly attenuated in group IP as compared with group I/R.Conclusion The mechanism by which lung ischemic preconditioning mitigates lung I/R injury induced by CPB is related to upregulation of the expression of AQP1 in dog lung tissues.

The endophytic microorganisms found widely in many kinds of plants mediate various effects to theirs hosts. In this study, seven different dominant endophytes (SDE01 to 07) isolated from a Hy-peraccumulator-Solanum nigrum L. were resistant to Cd2+, and the strain SDE06 survived even in the medium containing 80 mg/L of Cd2+. Bacteria strain SDE06 was identified as Bacillus sp.. The removal of Cd2+ of SDE06 in different conditions were studied. Under the optimal conditions, the incubating time was 36 h, the solution pH 6.0, the temperature was 37?C and the Cd2+ concentration of medium was 20 mg/L, the highest removal rate was up to 80.2% at this condition.

Objective To investigate the hemodynamics of increasing portal venous pressure(PVP) in hepatocellular carcinoma patients complicated with hepatic arterioportal vein fistulas (HAPVF)and the diagnosis and therapy of intractable upper gastrointestinal hemorrhage caused by HAPVF.Methods One hundred and fifteen cases of hepatocellular carcinoma with upper gastrointestinal hemorrhage were checked by hepatic arteriography and were treated through orifices embolization in cases with severe HAPCF by coils and/or ethanol. Results Twenty-six out of 31 patients suffering intractable upper gastrointestinal hemorrhage have severe HAPVF(the main stem of portal veins are visible).However,there are only 15 patients with light HAPVF among the 84 patients who have mild upper gastrointestinal hemorrhage (the main stem of portal veins are invisible).After the embolization,all of the 26 patients who have severe HAPVF stopped bleeding.Among them,the main stem of hepatic arteries are occluded in 2 patients. Conclusion The existence of severe HAPVF should be taken into consideration when intractable upper gastrointestinal hemorrhage occurs in hepatocellular carcinoma patients,and it can be diagnosed through hepatic artery DSA.Orifice embolization is the most effective method for such kind of hemorrhage.

Objective To investigate the spousal transmission of human immunodeficiency virus (HIV)and its related factors in HIV epidemic area,which can be beneficial to prevent HIV from transmitting.Methods Three hundred and forty-six couples with one spouse were anti-HIV positive were cross-sectionally investigated.Blood samples were taken from the spouse of subjects whose anti- HIV were positive to detect the anti-HIV antibody and from 70 acquired immune deficiency syndrome (AIDS)patients to do the sequencing of the serum HIV provirus DNA.Results In 346 couples,99 were infected by spousal transmission and its transmission rate was 28.6%.One spouse of 125 couples were infected with HIV by paid blood donation,14.4%(18)of the other spouse were infec- ted by spousal transmission.One spouse of 135 couples were infected by paid blood transfusion, 23.7%(32)of the other spouse were infected by spousal transmission.Eighty-six couples were infec- ted by extramarital sexual contact,49(57.0%)got spousal transmission.Thirty-seven(69.8%) subjects were infected by husband-to-wife transmission and 12(36.4%)were from wife to husband. The difference between them was significant(P
