ObjectiveTo assess the efficacy of shoulder slings on rehabilitation of stroke patients with shoulder subluxation. Methods60 stroke patients with shoulder subluxation using shoulder sling or not were investigated retrospectively. ResultsAfter 3 months of rehabilitation training and nursing, both groups showed significant improvement in Fugl-Meyer Assessment of upper limbs and Barthel Index (P<0.05), but there is no significant difference between the two groups (P>0.05). ConclusionThere is no significant effect of should sling on upper limbs function and activity of daily living in stroke patients with shoulder subluxation.

Objective To compare effect of trichosanthin and methotrexate in the treatment of uterine scar pregnancy by a multi-center study. Methods 90 uterine scar pregnancy patients were selected from department of obstetrics and gynecology,in xinyang central hospital,the second affiliated hospital of zhengzhou university,zhumadian central hospital,using random number table divided into 2 groups.The control group of 45 cases were treated by methotrexate,gluteal muscle injection,50 mg one time,and took mifepristone 50 mg,two times a day,a week for a course of treatment;45 cases in the experimental group,were treated with trichosanthin,intramuscular injection of 1.2 mg/time,two times a day,and oral administration of bloven,0.6 g/d,a week for a course of treatment.The end of a course of treatment,2 groups of patients before and after treatment were compared of the serum progesterone level,β-HCG,side reactions after treatment.Results After treatment,progesterone levels were significantly reduced,and the experimental group levels were lower than the control group obviously,the difference has statistical significance(P<0.05).Serum -HCG level after the treatment significantly reduced,and the experimental group in serum -HCG levels were significantly lower,with statistical difference (P <0.05 ). Comparison of adverse reaction of the patients,the experimental group was obviously lower than control group,with statistically significant difference (P<0.05).Conclusion For the treatment of uterine scar pregnancy,trichosanthin and methotrexate have certain effect,but trichosanthin could lower serum progesterone,β-HCG levels more significantly than methotrexate,trichosanthin group side reaction rate is low.

Objective To observe the ultrastructure of pharyngeal armature of 7 species of sandflies in China. Methods The pharyngeal armatures of various sandflies were studied by scanning electron microscopy. Results The pharyngeal armature of sandfly consisted of pointed-teeth with various shape, number and arrangement among different species. Conclusion Such differences may provide the morphological proof for identification of species.

Objective To analyze the method of self-management education on the health status of patients with gastric carcinoma during chemotherapy. Methods Patients with gastric carcinoma (60 cases) were divided into the test group and the control group with 30 cases in each group. The two groups both received chemotherapy of complete cycle and general health education. The test group adopted self-management education based upon the above treatment, including collective education, group discussion and individual instruction. The treatment effect was appraised and compared by senior primary nurses. Results The recent total effective rate of chemotherapy in the test group was 76.7%, which was higher than that of the control group (50.0%). The level of life quality of the test group was also better than that of the control group (P<0.05). Conclusion Patients-centered self-management education could improve the health status of patients with gastric carcinoma during chemotherapy.

ObjectiveTo explore the effect of partial body-weight supported treadmill training(BWSTT) on gross motor function measure, walking ability and efficiency, and functional ambulation categories in children with cerebral palsy(CP).Methods35 children with cerebral palsy were assigned into 3 groups, BWSTT group(BWSTT with PT, n=11), TT group(treadmill training with PT, n=12), and PT group (n=12). Assessments were performed before treatment and 8 weeks and 12 weeks after treatment respectively. The evaluation items included the D & E dimensions of the gross motor function measures (GMFM), walking ability(WA), walking efficiency(WE)and Functional ambulation categories (FAC).ResultsNo statistically significant differences were found in age, gender, body height, as well as clinical assessments (GMFM, WA, WE and FAC) before treatment between 3 groups(P>0.05). There was statistically significant difference in each group 12 weeks after treatment, and BWSTT group showed statistical significant difference in GMFM, WA, WE and FAC.ConclusionBWSTT could significantly improve the walking ability and walking efficiency, and also the standing and walking ability of children with CP.

Objective To investigate subacute exposure of airborne particulate matter (PM) on pregnancy and fetal development in female mice. Methods Forty female and forty male ICR adult mice group (A), small (B) , middle (C) , large (D) or overdose (E) PM challenge groups (n = 8 - 11), and were administered with 30 μl of phosphate buffered solution (A) or resuspended standard PM SRM 1649a at 0.09 (B), 0.52 (C), 1.85 (D) or 69.2 (E) μg/μl, once per trid from d 0 till d 19 of pregnancy via instillation onto the base of the tongue. Fetal mice were harvested by cesarean section at the time when spontaneous delivery occurred. Body weight of the pregnant mice, gestational days, intrauterine survival and growth, hepatic and pneumonic histopathological changes of the fetal mice were investigated. Lung/body and liver/body weight ratios were calculated. Expressions of mRNA and protein of CYP1A1 in the fetal lung and CYP1 A2 in the fetal liver were assayed. Results (1) All of the pregnant mice survived pregnancy throughout the entire experiment. Body weight of the pregnant mice was not significantly different among all the groups at gestational d 1 and 7 (P ＞ 0.05), but significantly lower in group E [(41.8 ± 5.8) and (48.9 ± 8.9) g] than in group A [(45.9 ± 1.8) and (56.2 ± 4.9) g] at gestational d 14 and 18 (P ＜0.05). The gestational days were significantly decreased in group E [(19.3 ± 1.3) d] when compared with group A [(20.5 ± 0.7) d; P ＜ 0.05] and were not significantly different among groups A, B, C and D (P ＞ 0.05). Lung/body and liver/body weight ratios of the fetal mice were significantly increased in group E [(1.21 ±0.18) and (4.68 ±0.21)%] as compared with groups A, B, C and D (P＜0.05). (2)Mortality rates of the fetuses were significantly higher in group E (23.0%) than in groups A (0.8%), B (0.9%), C (1.7%) and D (3.7%) (P ＜ 0.05), but were not significantly different among groups A,B, C and D (P ＞ 0.05) despite of an increasing tendency. (3) Pathological changes in the liver and lung of the fetuses were conspicuous in group E. The fetal liver injury was histopathologically evidenced by deranged tissue structure, degenerated parenchyma of hepatic cells, and mildly stained cytoplasm. Adipose degeneration was represented by clear-boundary intracytoplasmic vacuoles in most of the liver cells, and cell pyknosis with heavily stained cytoplasm was observed in some of the liver cells. Inflammatory cell infiltration and focal necrosis were occasionally found in the hepatic tissue. The fetal lung exhibited bronchiole with narrow lumina, vascular engorgement in the submucosal layer, interstitial and alveolar edema, thickened alveolar septum, granulocyte and lymphocyte infiltrations within the pulmonary alveoli and around the bronchioles. The above pathological changes were lesser in groups C and D, and were not or least found in groups A and B. (4) Protein expressions of CYP1A1 in the fetal lung and CYP1A2 in the fetal liver were significantly increased in group E (1.20 ± 0.40 and 2.55 ± 0.89) when compared with group A (0.77 ±0.36 and 2.08 ±0.31) (P ＜ 0.05). mRNA expressions of CYP1A1 in the fetal lung were significantly increased in groups C (0.36 ±0.12), D (0.41 ±0.08) and E (0.43 ±0.11) compared with group A (0.21 ±0.10), and significantly increased in groups D and E compared with group B (0.28 ±0.10,P＜0.05). mRNA expressions of CYP1 A2 in the fetal liver were significantly increased in groups C (0.37 ±0.13), D (0.36 ±0.14) and E (0.43 ±0.16) compared with group A (0.21 ±0.03), and significantly increased in group E compared with group B (0.24± 0.11, P ＜ 0.05). Conclusions PM elicited embryotoxigenicity and resulted in adverse pregnancy outcomes in mice by intrauterine exposure of overdose PM. The expressions of cancer-related genes CYP1A1 and CYP1A2 were up-regulated in organs after the middle- and large-dose subacute exposure of PM, which may have a potential role on the future development.
