Objective To investigate the effect of neutrophil activation on pathogenesis of preeclampsia. Methods In 22 pregnant women with preeclampsia and 21 normal pregnant women at third trimester, neutrophil activation was examined by flow cytometry to assess the CD11b expression,and the levels of plasma endothelin 1(ET 1) and serum NO - 2 were also measured with no equilibrium radio immunoassay and with Griess assay respectively. Results The expression of neutrophil CD11b was significantly elevated in women with preeclampsia compared with that of normal pregnant women at third trimester [the mean fluorescence index of CD11b were 439 1? 169 1 and 321 2?166 3 respectively, P0 05). Conclusions The neutrophil CD11b expression is significantly elevated in preeclampsia. The increased neutrophil activation may cause the damage of vascular endothelium and result in compensatory increase of NO release in endothelial cells. It suggests that the neutrophil activation may play a key role in pathogenesis of preeclampsia.

Objective To survey the outcome of the Orientation and Mobility (O&M) Skills Training projects, a communities based rehabilitation which was advancing in Yunnan. Methods 310 blind subjects in model areas were assessed with the Assessment Standard of O&M Training for the Blind. Results 98.7% of subjects improved their mobility skills after receiving O&M skills training, that was 44.5% could walk independently in short distance, 34.5% in long distance, and 19.7% in complex surroundings in detail. There was no difference (P>0.05) among the different gender, educated level, and visual loss level, however, there was significant difference (P<0.05) made by the age level and the causes of disability of vision. Young and middle-aged subjects have better training result than the aged, as well as the congenital blind ones than the postnatal ones. Conclusion O&M skills training in Community Based Rehabilitation Services is effective for visual rehabilitation.

The change in serum laminin (LN) level and its clinical significance in epithelial ovarian tumor were investigated. The LN levels in serum and ascites samples from 69 patients with epithelial ovarian tumor and 42 cases as control group before and after operation were analyzed by radioimmunoassay. The results showed that the serum LN levels in the patients with malignant tumors (157.85 +/- 14.37 ng/ml) were significantly higher than that in the control group (125.14 +/- 7.03 ng/ml) and in the patients with benign tumors (128.36 +/- 8.75 ng/ml) (both P < 0.01) before operation. The serum LN levels in the malignant group were decreased significantly after operation as compared with those before operation (P < 0.05). The serum LN levels in low-differentiated tumors was higher than those in moderate-differentiated tumors and high-differentiated tumors (P < 0.05). The LN levels in ascites (172.94 +/- 15.26 ng/ml) was significantly higher than in serum (161.34 +/- 6.59 ng/ml) (P < 0.05) in malignant tumors. The serum LN levels in the patients with lymph node metastasis (165.41 +/- 19.91 ng/ml) was obviously higher than those without lymph node metastasis (152.35 +/- 10.34 ng/ml) (P < 0.05). It was concluded that LN levels in serum and acistis were remarkably increased in malignant epithelial ovarian tumors, suggesting that LN might be one of important diameters reflecting tumor biological characteristics.

Objective To observe the effect of gheocorticoid by oral medication or intrathoracic iniection on the expression of IL-6,IL-8 and sIL-2R in gerum and pleural fluid in patients of tuberculous pleurisy.Methods Twenty tuberculous pleurisy patients were treated with ghcocortieoid by oral medication (oral group)and 20 cases by intrathoracic injection(injection group).ELISA wag employed to detect the levels of IL-6,IL-8 and sIL-2R in serum and pleural fluid before treatment and 3,6 and 9 days after treatment.Results The levels of serum IL-6 and IL-8 decreased and sIL-2R increased obviously in injection group at 3,6 and 9 days after treatment(P＜0.01).Meanwhile the levels of IL-6 and IL-8 in pleural fluid decreased and sIL-2R increased obviously(P＜0.01).The levels of IL-6 and IL-8 were significantly lower and the levels of aIL-2R were significantly higher in injection group than those in oral group(P＜0.01).One month after treatment,the rate of complete absorpion of pleural fluid was higher in injection group(80%)than thatin oral group(45%),the rate of pachynsis pleurae was lower in injection group(10%)than that in oral group(40%),P＜0.05.Conclusions Intrathoracic injection of ghcocorticoid shows stronger suppression of cellular immune function in cavum pleurae and weaker suppression of the general immune sysmm than oral medication.Intrathoracic injection of glucocorticoid can increase the therapeutic effect and decrease side effect in tuberculous pleurisy.

Background:The efficacy of standard triple therapy for eradication of Helicobacter pylori(Hp)is decreasing in recent years,and bismuth-containing quadruple regimen becomes the first-line therapy for Hp infection. However,the application of bismuth has some limitations. Aims:To investigate the efficacy of proton pump inhibitor(PPI)-based standard triple therapy combined with teprenone for Hp eradication. Methods:A total of 155 Hp-infected chronic gastritis patients were enrolled from Jan. 2013 to Dec. 2014 at Aerospace Center Hospital,and were randomly assigned into standard triple therapy group,bismuth-containing quadruple therapy group and teprenone-containing quadruple therapy group. Patients in standard triple therapy group were given rabeprazole sodium 20 mg + amoxicillin and clavulanate potassium 914 mg +clarithromycin 500 mg bid for 10 days. Patients in bismuth-containing quadruple therapy group were given standard triple therapy combined with bismuth potassium citrate 0. 6 g bid for 10 days. Patients in teprenone-containing quadruple therapy group were given standard triple therapy combined with teprenone 50 mg bid for 10 days. Symptoms of patients were evaluated before and after eradication therapy. Four weeks after the end of therapy,13 C-urea breath test( UBT)was reexamined to assess the status of Hp infection. Results:One hundred and fifty-two patients completed the treatment course. By ITT analysis,the eradication rates of standard triple therapy group,bismuth-containing quadruple therapy group and teprenone-containing quadruple therapy group were 69. 8%(37 / 53),86. 5% (45 / 52)and 88. 0% (44 / 50), respectively;by PP analysis,the eradication rates of the three groups were 71. 2%(37 / 52),88. 2% (45 / 51)and 89. 8%(44 / 49),respectively. Eradication rates analyzed by ITT and PP in bismuth-containing quadruple therapy group and teprenone-containing quadruple therapy group were significantly higher than those in standard triple therapy group(P <0. 05),but no statistically significant difference was found between these two groups( P > 0. 05). Relieving rates of abdominal pain,abdominal distention and belching in bismuth-containing quadruple therapy group and teprenone-containing quadruple therapy group were higher than those in standard triple therapy group,but statistically significant difference was only found in relieving of abdominal pain between teprenone-containing quadruple therapy group and standard triple therapy group(88. 9% vs. 70. 3% ,P < 0. 05). Adverse effects included transient and mild nausea,diarrhea and black stool, etc. Conclusions:Teprenone-containing quadruple regimen are effective for Hp eradication and symptoms relieving with no severe adverse effects,the efficacy is comparable with bismuth-containing quadruple regimen.

Objective To discuss the influence of psychological education on the resourcefulness of perioperative breast cancer patients. Methods Two hundred breast cancer patients from a first-class hospital in Fujian province were randomly assigned to the control group, in which routine care was done, and an intervention group, in which psychological education curriculum was employed at three stages on the basis of routine care. The resourcefulness scale was used in both two groups before and after the intervention to evaluate the score of individual and social resourcefulness and the total score of resourcefulness in these two groups. Results As to the control group, the score on individual resourcefulness and the total score on resourcefulness before and after the intervention had no significant differences (P>0.05), but the difference in the social resourcefulness scores before and after the intervention was statistically significant (P<0.05). The differences in the scores on the individual resourcefulness, social resourcefulness and the total score on resourcefulness in the intervention group before and after the intervention were all statistically different (P<0.001). What′s more, the scores of individual resourcefulness, social resourcefulness and the total score of resourcefulness between these two groups after the intervention were statistically different (P<0.001) as well. The scores of the intervention group were significantly higher than those of the control one. Conclusion The psychological education can significantly improve the resourcefulness level of perioperative breast cancer patients, which can help individuals to manage stress effectively.

Task performance and contextual performance are effective approaches by which high quality nursing care in operating room could be reasonably assessed.

Capsule endoscopy is an important method for the diagnosis of small intestinal diseases, and that capsule endoscope retention in the small intestine is the most important and serious complication in the process of this technique.It often occurs in the diseases of intestinal stenosis caused by Crohn′s disease, small intestinal tumor, intestinal tuberculosis and after abdominal surgery.Once capsule endoscope retention occurs, it is necessary to observe the symptoms of intestinal obstruction, to treat the primary disease actively, and it is very important to remove the foreign body by the enteroscopy or surgical intervention timely.

OBJECTIVE: To evaluate the immuno-modulatory effect of short course administration of somatostatin (stilamin) continuously at early stage in patients with severe acute pancreatitis (SAP). METHODS: Thirty-nine patients with SAP (22 men, 17 women; the middle age was 49 years)were randomly allocated into control group (20 patients treated with non-surgical integrated traditional Chinese and Western medicine) and treatment group (19 patients treated with somatostatin administered intravenously at a dosage of 250 mug/h for consecutive 72 hours as well as the treatment for the control group). Laboratory parameters, including the expressions of CD(3), CD(4) and CD(8) in lymphocytes (tested by flow cytometry) and C reactive protein (CRP), and indexes of therapeutic effect, including the occurrence of organic dysfunction, local complication and mortality between the two groups were compared. Another group of 30 healthy volunteers (19 men, 11 women; the middle age was 47 years) were recruited for testing the normal levels of CD(3), CD(4) and CD(8). RESULTS: (1) The levels of CD(3), CD(4) and CD(4)/CD(8) in lymphocytes before treatment in both groups were significantly lower than those in the healthy subjects (P<0.05), but there were no statistical differences between the two groups. At the 4th day, CD(3), CD(4) and CD(4)/CD(8) increased significantly in the treatment group (P<0.05) while no changes in the control group; the levels of CD(4) and CD(4)/CD(8) in the treatment group were also higher than those in the control group (P<0.05). (2) The CRP levels of the 2 groups showed no statistical difference before and 4 days after the treatment, but the CRP level in the treatment group was significantly lower than that in the control group at the 7th day (P<0.05). WBC count, serum levels of amylase, lipase, lactate dehydrogenase, aspartate aminotransferase, as well as the score of APACHE II in the treatment group recovered more quickly than those in the control group (P<0.05). (3) The occurrences of organic dysfunctions, local complications and mortality in both groups were not statistically different. CONCLUSION: The short course administration of somatostatin continuously at early stage can reduce the inflammatory response, up-regulate the cell immune function and improve the conditions of the patients with SAP, but its effect on mortality and morbidity needs further study.
