Objective To explore the clinical characteristics and the remedial measurement of measles complicated with severe pneumonia and the acute respiratory distress syndrome(ARDS) in children.Methods From Jan 2004 to Jul 2007,clinical data of 32 cases with measles complicated with severe pneumonia and ARDS in PICU of Chongqing Children's Hospital were retrospective analyzed.In addition,the ratio of partial pressure of oxygen in arterial blood fractional concentration of oxygen in inspired gas[pa(O2)/FiO2] between the death group and survival group,the mortality rates between the hormone therapy group and control group were performed.Results Sixteen cases were cured and 16 cases were died,with the mortality rate 50%.The ratio of pa(O2) /FiO2 before mechanical ventilation in death group was lower than that in the survival group [(11.93?1.67) kPa,(21.77?1.16) kPa,respectively,P0.05).Conclusions ARDS is a severe complication in children with measles pneumonia and associated with a high mortality,which requires early diagnosis and intervention to improve survival rate and prognosis.The ratio of pa(O2)/FiO2 may provide reference to evaluation for severity and prognosis of ARDS.

AIM: To discuss the single application on iris localization technology in excimer laser for the treatment of astigmatism.
METHODS:Totally 203 cases (406 eyes) of laser in situ keratomileusis ( LASIK ) in the treatment of compound myopic astigmatism patients were operated from November 2011 to November 2012 in our hospital. They were divided into two groups. One was observation group using iris localization and the other was control group using routine operation. Patients in the observation group of 100 cases ( 200 eyes ) , aged 18-43 years old, spherical diopter was - 1. 25 to - 8. 75D, astigmatism was -1. 0 to -3. 25D. In control group, 103 patients ( 206 eyes ) , aged 19-44 years old, spherical diopter was -1. 75-9. 50D, astigmatism was -1. 0 to -3. 25D. The patients in the observation group before the application of WaveScan aberrometer check for iris image, spherical lens, cylindrical lens and astigmatism axis data operation, only single application of iris location, without using wavefront aberration guided technology, laser cutting patterns for conventional LASIK model, spherical, cylindrical mirror and astigmatism axis  RESULTS: Postoperative residual astigmatism, the observation group was significantly better than the control group. Astigmatism axial measurement after operation, the observation group was significantly less than that of the control group. Postoperative visual acuity at 6mo, the observation group was better than that of the control group. The difference was statistically significant.
data source to preoperative wavefront aberration results. The control group received routine LASIK. It was applicated comprehensive optometry optometry respectively to examine astigmatism and axial, based on the computer analysis during the preoperative, 1wk after the operation, and 6mo. Analysis of using SPSS 17 statistical software, it was independent-sample t test between the two groups of residual astigmatism and astigmatism axis.
CONCLUSION: For patients who cannot complete the wavefront aberration guided treatment of astigmatism, can separate the application of wavefront aberration analyzer automatic iris recognition technology to improve precision of astigmatism treatment, give full play to advanced technical performance of equipment, which has good application value.

So far there exists no corresponding quality test procedures and grading standards for the seed of Prunus humilis, which is one of the important source of base of semen pruni. Therefor we set up test procedures that are adapt to characteristics of the P. humilis seed through the study of the test of sampling, seed purity, thousand-grain weight, seed moisture, seed viability and germination percentage. 50 cases of seed specimens of P. humilis tested. The related data were analyzed by cluster analysis. Through this research, the seed quality test procedure was developed, and the seed quality grading standard was formulated. The seed quality of each grade should meet the following requirements: for first grade seeds, germination percentage ≥ 68%, thousand-grain weight 383 g, purity ≥ 93%, seed moisture ≤ 5%; for second grade seeds, germination percentage ≥ 26%, thousand-grain weight ≥ 266 g, purity ≥ 73%, seed moisture ≤9%; for third grade seeds, germination percentage ≥ 10%, purity ≥ 50%, thousand-grain weight ≥ 08 g, seed moisture ≤ 13%.

Objective To clne huma PAIl gene and prepare its monoclonal antibodies(McAbs) for determination of its expression in breast cancer cells.Methods Human PAI1 gene eDNA was amplified by RT-PCR from human breast cancer cell line MDA231 and inserted into the prokaryotic expression vector, which expressed fusion protein of MS2-PAI1 in E.coli.Fusion protein of MS2-PAI1 was purified and used for immunizing BALB/C mouse.Traditional hybridoma technology was used to produce hybridoma cells for preparation of monoclonal antibodies.Western blot and immunohistochemistry were used to detect PAI1 expression in breast cancer.Results The 1209 bp full PAI1 gene was cloned.The two hybridoma cell lines that secreted specific monoclonal antibodies against human PAI1 were identified by ELISA.The immunoglobulin subclasses of the McAbs were IgG1.The McAbs can specifically recognize PAI1 but not other proteins.Western blot showed that the McAbs against PAI1 can specifically react with MS2-PAI1 fusion protein and endogenous proteins in cells.The positive reaction was found in breast cancer cell line MDA231 and breast cancer tissues by immunochemical staining.Conclusions The McAbs against human PAI1 are successfully prepared by hybridoma technology with MS2-PAI1 fusion protein expressed in E.coll.It has been shown that PAI1 can be expressed in MDA231 and breast cancer tissues.The McAbs against PAI1 could be a useful tool for the further study of the human PAI1 functions and detection of clinical tumor samples.

OBJECTIVE: To study ApoB gene genetic polymorphism of Han nationality and Mongolian nationality in midwest area of Inner Mongolia. METHODS: Some unrelated individuals of Han nationality and Mongolian nationality in midwest area of Inner Mongolia were selected. Polymerase chain reaction-restriction fragment length polymorphism technology was used to check the presence of Xba I (X+) and EcoR I (E-) sites of rare alleles. The genotype frequency, allelic frequency and population genetics parameters were calculated. RESULTS: The frequencies of Xba I (X+) and EcoR I (E-) rare alleles were 2% and 4.6% in Han population. There was no Xba I (X+) or EcoR I (E-) rare alleles found in Mongolian nationality. CONCLUSION The allelic frequencies of ApoB gene Xba I and EcoR I sites are very different in different races. These sites may be used in identification of ethnicity.

Objective:To observe the effect of moxibustion on T lymphocyte subsets in peripheral blood of rats with gastric cancer. Methods:Sixty healthy Sprague-Dawley (SD) rats were adaptively fed for one week. By the random number table method, 10 rats were randomly selected as a blank group, and 12 rats were randomly selected to simulate the tumor transplantation process; after transplantation, 10 rats were randomly selected as a sham operation group. The remaining 38 rats were used to prepare gastric cancer models by gastric transplantation of the Walker-256 tumor tissue; 8 rats were randomly selected to verify the successful modeling after 7 d; the remaining 30 rats were randomly divided into a model group, a moxibustion group and an infrared group by the random number table method, with 10 rats in each group. From the first day of enrollment, the rats in the moxibustion group received mild moxibustion at Zhongwan (CV 12), Guanyuan (CV 4) and bilateral Zusanli (ST 36) (the first group) and bilateral Pishu (BL 20) and Weishu (BL 21) (the second group), and the two groups of acupoints were alternated every other day. The rats in the infrared group received infrared radiation on the stomach area and the area on the back between the T12-T13 spinous processes, the two areas were alternated every other day. Rats in the moxibustion group and the infrared group were treated for 20 min each time, once a day for 21 d. Rats in the blank group, the sham operation group, and the model group were simultaneously grasped and fixed, and no other treatment was performed. After 21 d of intervention, the rats in each group were fasted for 12 h, and blood was collected from the orbits. The numbers of CD3+, CD3+CD4+, CD3+CD8+ T lymphocytes in peripheral blood were determined by flow cytometry, and the ratio of CD3+CD4+/CD3+CD8+ was calculated. The rats were sacrificed and the thymus was dissected under sterile conditions to calculate the thymus index. Results:Compared with the blank group, the thymus index, peripheral blood CD3+, CD3+CD4+, CD3+CD8+ and CD3+CD4+/CD3+CD8+ ratio in the sham operation group did not change significantly (allP>0.05). Compared with the blank group, the thymus index of the model group was increased (P<0.05), the CD3+ and CD3+CD8+ T lymphocytes were increased (bothP<0.01), and the CD3+CD4+/CD3+CD8+ ratio was decreased (P<0.05). Compared with the model group, the thymus index of the moxibustion group was increased (P<0.01), and CD3+, CD3+CD4+ and CD3+CD8+ T lymphocytes and the ratio of CD3+CD4+/CD3+CD8+ in peripheral blood were increased (allP<0.05). Compared with the infrared group, the thymus index of the moxibustion group was significantly increased (P<0.05), the CD3+ and CD3+CD4+ T lymphocytes in the peripheral blood were significantly increased (bothP<0.01), and the CD3+CD8+ was increased (P<0.05). Conclusion:Moxibustion can significantly increase the thymus index of gastric cancer-bearing rats and activate CD3+CD4+ and CD3+CD8+ T lymphocytes in peripheral blood.
