To investigate the influence of six exogenous pathogenic factors on asthma in children and to observe the changes of microscopic indexes in cold- and heat-type asthma. Logistic regression analysis was applied to analyze the influence of six exogenous pathogenic factors and the changes of serum level of IgE, eosinophil (EOS) counting, contents of third component of complement (C3) and C-reactive protein (CRP) were observed. The exogenous factors of wind, cold, damp, wind-cold mixture and cold-damp mixture were the risky factors of asthma. Serum levels of IgE and EOS were higher in cold-type asthma and serum contents of C3 and CRP were higher in heat-type asthma (P

Objective To summarize the characteristics of regional lymph node metastasis in patients with early gastric cancer and analyze the risk factors for lymphatic metastasis. Methods 103 cases surgically treated for early gastric cancer in the Third Hospital of Peking University between March, 1988 and March, 2009 were analyzed retrospectively. Several clinicalpathologic variables including patients' age, gender, size of tumor, tumor location, macroscopic type, histological type, invasion depth were investigated by using chi-square test and logistic regression analysis for the possible relationship to lymphatic metastasis. Results The rate of lymph node metastasis in early gastric cancer was 17.5% (18/103), which in mucosal cancer was 4. 1% (2/49). Submucosal cancer had a lymph node metastatic rate of 29. 6% (16/54). Logistic regression indicated that invasion to submucosa and tumor size > 2 em were independent risk factors for lymph node metastasis of early gastric cancer. Metastatic cases of mucosal cancer were all signet ring cell cancer with diameters more than 2 cm. Lymph node metastatic rate in submueosal cancers within 2 cm was 16. 1% (5/31), that in > 2 cm submucosal cancers was 47. 8% (11/23) (P = 0. 012). Rate of lymph node metastasis in well-differentiated cancers was 0 (0/13), that in moderately-differentiated, poorly differentiated and signet ring cell cancers were 18. 2% (4/22), 16. 7% (5/30) and 23.7% (9/38) respectively (P = 0. 294). Patients' age, gender, tumor location and macroscopic type showed no relationship with lymph node state. Conclusion The tumor size and invasion depth are related with lymph node metastasis in early gastric cancer, considering these factors and assessing lymph node state is essential to appropriate therapeutic options for early gastric cancer.

As one of the heat shock protein fam ily m em bers,αB-crystallin possesses biological proper-ties of m olecular chaperones and anti-apoptotic effects. Multi-factor injuries, such as retinopathy, inflam-m ation and nervous system diseases, have a closely relationship w ith αB-crystallin. T his paper review s the research progress of the expression and m echanism ofαB-crystallin in retina and extraocular tissues and organs.

Objective To investigate concentration and distribution in blood and tissues of form icacid after m ethanol intoxication in rats. Methods The Sprague-Dawley rats were divided into groups for con-trol group and 3-day and 7-day intoxication treatm ent groups. The experim ental groups were adm inis-tered m ethanol by gavage with the initial dose of 8 m L/kg and followed with 4 m L/kg supplem ental dose 24 h later. After 3 days and 7 days later, rats were killed by decapitation. Then sam ples of cardiac blood, liver, kidney, brain, heart and stom ach of each group were collected. Form icacid concentrations were detected by high perform ance liquid chrom atography. Results Form icacid concentrations in tissues were higher than in blood. Com pared with 3-day intoxication group, there was an increase form icacid of concentration in brain and stom ach in 7-day intoxication group, while a decrease in liver and kidney (P<0.05). Conclusion H igh perform ance liquid chrom atography could be used to accurately detect form icacid. As the m etabolite of m ethanol, form icacid accum ulates in rat blood and tissues after intoxication and the concentrations in organs and tissues are obviously higher than in blood.

Objective To explore the clinical significance of expression of soluble mesothelin relatedprotein(SMRP)and carbo-hydrate antigen (CA125)in the serum and tumor tissues of the patients with ovarian cancer.Methods The preoperative and post-operative levels of SMRP and CA125 in serum and ovarian cancer tissues were detected in 82 patients with ovarian cancer (group A),76 cases of benign ovarian tumor (group B)and 53 healthy women (group C)by using ELISA and the immunohistochemical method respectively.Serum levels of SMRP and CA125 in the ovarian cancer patients were measured after one year by ELISA.The correlation among the various statistical indexes was analyzed.Results The positive expression rates of SMRP and CA125 in the group A were significantly higher than those in the group B(P <0.05);compared with the group B and C,the preoperative serum level of CA125 and SMRP in the group A was significantly increased (P <0.001);the preoperative serum CA 125 level in the group B was higher than that in the group C;compared with the stage Ⅰ and Ⅱ,the serum CA125 and SMRP in the stage Ⅲ and Ⅳ of o-varian cancer were significantly increased(P <0.05 );compared with before operation,the postoperative SMRP and CA125 levels were significantly decreased(P <0.05).After 1 year of discharge from hospital,compared with the basically stable patients,serum CA125 and SMRP levels in the patients with ovarian cancer recurrence were significantly increased(P <0.05).The sensitivity and specificity for diagnosing ovarian cancer,any single detection was inferior to the combination detection of CA125 and SMRP.Conclu-sion The combination detection of CA125 and SMRP has an important value for increasing the sensitivity and specificity of ovarian cancer diagnosis,early diagnosis,illness condition monitoring and effect evaluation.

Objective To analysis complications and its associated risk factors of high intensity focused ultrasound (HIFU) in treatment of uterine leiomyoma for selecting rationale indicated patients and reducing complications. Methods Medical documents of 171 patients with 231 leiomyomas in total treated by HIFU were studied retrospectively. Common complications were categorized and analyzed, the relationship between risk factors and complications were studied. Results Common complications in treatment of uterine leiomyomas by HIFU were 71.9% (123/171) of abdominal pain, 17.5% (30/171) of vaginal bloody discharge, 8.2% (14/171) of sacroiliac or buttock pain, 7. 6% (13/171) of skin blister,4. 7% (8/171) of leg pain, 2. 9% (5/171) of hematuria and 1.8% (3/171) of febrile. By logistic regression analysis, the factor correlated with abdominal pain included diameter of uterine leiomyomas,sonication time and average power (P < 0. 05). The factor correlated with sacroiliac or buttock pain was uterine leiomyomas located in posteriors of uterine wall(P <0. 05); the factors correlated with vaginal bloody discharge were sonication time and type of uterine leiomyomas (submucous > intramural > subserous, P <0. 05); the factors correlated with skin blister was sonication time (P < 0. 05). There were no statistical relationship between multiple factors and leg pain, hematuria, febrile (P > 0. 05). Conclusion The modality of high-power and short-term treatment might reduce complications of HIFU ablation.

Objective To compare the correlation between contrast vision (CV) and sweep visual evoked potential acuity (SVEP-A) among people with emmetropia, mild myopia, and moderate myopia. Meth-ods The CV and SVEP-A were tested individually in 96 eyes from healthy young volunteers, including 37 eyes of emmetropia, 27 eyes of mild myopia, and 32 eyes of moderate myopia. The statistic analysis was done by ANOVA analysis and rank sum test. Results (1) With the decrease of contrast, CV and SVEP-A decreased in every group. (2) At 100% contrast, the difference of CV between emmetropia and mild myopia had statistical significance (P<0.05). At 100%, 25% and 10% contrast, the difference of CV between emmetropia and moderate myopia had statistical significance (P<0.05). (3) In the same group, the difference of 100% and 25% contrast had statistical significance (P<0.05). So was between 100% and 10% contrast. (4) At 100% and 10% contrast, the difference of CV and SVEP-A had statis-tical significance (P<0.05). Conclusion The CV of myopia relates to many factors including ametropia and fundus lesions. The correction of ametropia is important to the values of CV and SVEP-A.
