Objective To explore the relationship between preoperative serum pro-adrenomedullin (pro-ADM) in the patients with closed rupture of small intestine,and postoperative secondary abdominal infection,and to study the value of postoperative serum pro-ADM in assessment of severity of postoperative secondary abdominal infection of this patients.Methods Eighty-five patients with closed rupture of small intestine treated in the emergency surgery from June 2014 to May 2015 were selected.According to the presence of postoperative abdominal infection or not,these patients were divided into infection group and non-infection group.The infection group was further divided into SIRS,sepsis,severe sepsis,septic shock subgroups as per the severity of infection.The levels of serum pro-ADM,interleukin-6 (IL-6),C-reactive protein (CRP) were determined and the acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score was calculated at admission and the first day、the second day and the third day after operation.Comparisons of these biomarkers were carried out to find out the factors associated with postoperative abdominal infection.In addition,ROC curve was used to verify the factors for predicting the abdominal infection of these patients after operation.The relationship between serum levels of pro-ADM and APACHE Ⅱ score after operation was analyzed.The severity of abdominal infection after operation was assessed with laboratory findings.Results Compared with non-infection group,preoperative and postoperative serum pro-ADM (P =0.03,P ＜ 0.01),IL-6 (P =0.02,P ＜0.01) levels and APACHE Ⅱ scores (P ＜ 0.01,P ＜ 0.01) were significantly higher in infection group (P ＜ 0.05).In the infection groups,the postoperative levels of serum pro-ADM and APACHE Ⅱ scores were increased with the severity of infection increased (r =0.924),and the difference between the groups was statistically significant (P ＜ 0.05),but there were no significant differences in IL-6 and CRP levels between two groups.Conclusion (1) The serum levels of pro-ADM before operation has value in predicting the genesis of abdominal infection in these patients after operation.(2) The serum levels of pro-ADM after operation has value in severity assessment of abdominal infection in these patients after operation.

AIM: To investigate the postoperative changes of binocular visual function in patients with congenital superior oblique palsy.METHODS: Eye position and binocular visual function were examined in 28 patients with congenital superior oblique palsy pre- and post-operatively. The results were statistically analyzed.RESULTS: The normal eye position rate after operation was 89.3%. There were 9 patients who gained simultaneous perception after operation, while 13 patients gained fusion as many as that gained stereoacuity. There was statistically significant difference between postoperative and preoperative eyes (P<0.05). Near stereoacuity was improved after operation. Patients who had better visual acuity and low strabismus degrees as well as fusion had a better recovery.CONCLUSION: The operation could improve the eye position and rebuild the binocular visual function of the congenital superior oblique palsy. The recovery of binocular visual function was related to visual acuity and strabismus degrees of the patients and whether they had fusion function.

Objective To establish the amplified luminescent proximity homogeneous assay(AlphaLISA) for the detection of Sendai virus.Methods The antigen concentration,serum concentration and the donor beads/acceptor beads ratio used in the AlphaLISA method were optimumized by the phalanx experiments, then the antibodies of Sendai Virus in 40 rat sera were detected by the established AlphaLISA method and ELISA detection method.The results were compared and the differentia between the two methods was confirmed by IFA.Results The optimum concentration of SV bio-peptide in AlphaLISA assay was 250 nmol/L, the best proportion of donor beads/acceptor beads ratio was 1 ∶1, using the concentration of 20 μg/mL and the serum dilution was 1∶10000.7 of the 40 rat sera were detected SV positive by ELISA, the positive rate was 17.5%, 8 of the 40 rat sera were determined SV positive by AlphaLISA, and the positive rate was 20.0%, the AlphaLISA positive serum was confirmed by IFA.Conclusions We preliminary established the Amplified Luminescent Proximity Homogeneous Assay(AlphaLISA) for the detection of Sendai virus.The sensitivity of the method is comparable to classical ELISA method, but this method use less serum samples and without washing steps.The method has some advantages in degeneracy and accuracy.

Arsenic trioxide albumin microspheres (As2O3-BSA-NS) were prepared by using methods of chemical cross-linking. The desirability function (DF), calculated according to the size (<1 microm) distribution, drug loading and drug trapping efficiency, was introduced as a total index for the microspheres formulation. Four factors, inculding W/O ratio, decentralization speed, BSA concentration and stirring stabilization time, were selected and arranged in an orthogonal experimental table. The release characteristic was studied by the drug release experiment in vitro. The four factors affected DF differently. Decentralization speed behaved as the maximum (P<0.01), followed by BSA concentration (P<0.05) and the W/O ratio dose (P<0.05). Stirring stabilization time did not influence DF (P>0.05). The release experiment in vitro showed that As2O3 in As2O3-BSA-NS was released more slower than pure As2O3. It was concluded that regular As2O3-BSA-NS may be prepared by the methods of chemical cross-linking, which was optimized by orthogonal experimental analysis of different factors, and the microspheres can release As2O3 slowly.

BACKGROUND: Herbal wines are an important part of the traditional Chinese medicine. The traditional medicated wine, lishizhen herbal wine,which can strengthen the immune function, has long been used for some chronic diseases. But,its mechanism remains unclear.OBJECTIVE: To explore the immune pharmacodynamics of lishizhen herbal wine and to observe its effect on the immune organs (spleen,pancreas) and lymphocyte transformation rate in mice.DESIGN: A randomized controlled experiment based on the observation of the experimental animals.SETTING: Department of integrated traditional Chinese and western medicine and the department of pharmacology of a university hospital MATERIALS: The experiment was completed at the Central Laboratory of Zhongnain Hospital of Wuhan University from September 2000 to December 2000. A total of 90 healthy Kuming mice were involved in the study.METHODS: Different doses of the herbal wine,cartinellin and the same volume of distilled water were given to the experimental animals. The drug administration was orally injected directly to the stomach of the animals once a day and 10 days consecutively. One hour after the last administration,the animals were put to death. Then,the thymus gland and the spleen were taken out and weighed to calculate the indexes of the thymus gland and the spleen. In the last three days of the administration phytohemagglutinin(PHA)was injected intramuscularly at a dose of 10 mg/kg once per day. Two hours after the last administration, the tails of the mice were cut out, the blood samples were taken to perform the Wright' s staining,and 100 lymphocytes were counted under immersion and the transformation rate was calculated.MAIN OUTCOME MEASURES: Primary results: ① The effect on the immune organs of normal mice; ② The effect of PHA on stimulating the lymphocyte transformation in mice. Secondary results: ③ The death condition of the experimental animalsRESULTS: Different doses of the herbal wine increased the spleen index in different degrees. The effect of medium dose group was obvious[(3.71± 0.78) g/kg] (P <0.05),and the thymus gland index increased a little (P>0.05). The cartinellin in the positive control group increased the spleen index[(3.79±0.91 ) g/kg] and there was no impact on thymus gland index. The transformation rates of the lymphocytes of different groups were increased to a different degree and presented a good quantity-effect relationship,especially the group administered a large dose[(45±14)%] (P<0. 01).CONCLUSION: Lishizhen herbal wine has an effect of increasing cellular immune function.
