Ureaplasma urealyticum(UU)is one of the most common pathogen in childbearing age women.The proportion of neonate especially premature baby infected with UU is increasing yearly.UU infaction is related with premature labour,low birth weight,bronchopulmonary dysplasia,chronic lung disease,respiratory distress syndrome and other perinatal diseases by promoted the expression of inflammatory cytokines,increasing the inflammatory response and interfering inflammation clear.There still has controversial point to treat perinatal diseases caused by UU infection by erythromycin,azithromycin,pulmonary surfactant,steroid.

To observe the clinical efficacy of Artisan iris-clip intraocular lens ( lOL) implantation on cataract with a wide range of lens dislocation.
●METHODS: Twenty-four hospital patients (28 eyes) of cataract with lens subluxation by trauma (20 patients, 20 eyes) and Marfan's syndrome (4 patients, 8 eyes) during May 2007 to December 2011 were selected. All of them underwent phacoemulsification or an anterior vitrectomy and Artisan iris - clip lOL implantation at stage Ⅰ. Postoperative visual acuity, corneal endothelial cell count, intraocular lens position and postoperative complications were observed. Follow-up time was 6mo.
●RESULTS: Compared with the preoperative, postoperative best corrected visual acuity improved to varying degrees, visual acuity of 0. 1-0. 5 was in 20 eyes, 0. 5-1. 0 in 8 eyes. After followed up 1-6mo, no artificial lens shift, iris inflammation, iris atrophy and corneal decompensation and other complications were observed.
●CONCLUSlON: Cataract surgery with a wide range of lens dislocation is difficult, but as long as surgeons who have a wealth of clinical experience and superb skills, still can carry out phacoemulsification surgery or anterior vitrectomy and Artisan iris - clip lOL implantation and obtain a better outcome.

OBJECTIVETo investigate the possibility of evaluation the Chinese medicinal formulae with immune regulation effects according to the immunomics of traditional Chinese medicine.

METHODThe possibility of Chinese medicinal formulae with immune regulation effects was obtained from the discriminant equation of the Chinese medicine with immune regulation effects. The original articles about the Chinese medicinal formulae with immune regulation effects were found since 1980 in CNKI. Using literatures determinate immune effects.

RESULTThere were 53 kinds, that with calculated determination, from total 60 Chinese medicinal formulae with literatures determinate on immune regulation effects. The coincidence was 88% (53/60). The discriminant score was 0. 89 +/- 0. 03 in group one (there were two or more than two articles have been published to support the medicines immune effects and the articles were finished by different unites independently) and was 0.60 +/- 0.29 in group of random Chinese medicinal formulae. There was a significant deviation (P < 0.05).

CONCLUSIONIt was proved preliminarily that the principle of calculation presented in this paper is valuable for the immunomics of traditional Chinese medicine.

SHIV-CN97001 played an important role in assessing the immune effect and strategy of the AIDS vaccine which included genes of the predominant prevalent HIV-1 strain in China. In this study, SHIV-CN97001 was in vivo passaged serially to construct pathogenic SHIV-CN97001/rhesus macaques model. To identify variation in the gp120 region of SHIV-CN97001 during passage, the fragments of gp120 gene were amplified by RT-PCR from the plasma of SHIV-CN97001 infected animals at the peak viral load time point and the gene distances (divergence, diversity) were calculated using DISTANCE. The analysis revealed that the genetic distances of SHIV-CN97001 in the third passage animals were the highest during in vivo passage. It had a relationship between viral divergence from the founder strain and viral replication ability. The nucleic acid sequence of the V3 region was highly conservative. All of the SHIV-CN97001 strains had V3 loop central motif (GPGQ) and were predicted to be using CCR5 co-receptor on the basis of the critical amino acids within V3 loop. These results show that there was no significant increase in the genetic distance during serial passage, and SHIV-CN97001 gp120 gene evolved toward ancestral states upon transmission to a new host. This could partly explain why there was no pathogenic viral strain obtained during in vivo passage.

Objective To observe the protective effect of silybin-phosphatidylcholine compound(SPC) on acute liver damage induced by alpha-naphthylisothiocyanate(ANIT) in mice.Methods Forty mice were randomly divided into 4 groups:normal group,model group,SPCⅠgroup,SPCⅡgroup.Intragastric administration of 0.5% carboxymethylcelluloes-Na(CMC-Na) suspension were given to the normal and model group,and 2 quantities of SPC suspension(150 and 300 mg/kg) were respectively given to SPCⅠ and SPC Ⅱ groups for 1 week.At 12 h after last administration of SPC,all of groups besides normal were given ANIT(dissolved in peanut oil,(60 mg/kg)) by lavage and the normal group just only were given peanute oil by the same volume and same way.After 16 h of ANIT administration,the levels of serum alanine transferase(ALT),aspartate aminotransferase(AST),serum total bilirubin(TB),malondialdehyde(MDA) and superoxide dismutase(SOD) were detected by biochemical method.Results Serum levels of ALT,AST,TB and MDA markedly increased after ANIT was administered via intragastric tube,and the level of serum SOD also decrease.SPC could obviously inhibit the alteration of the activities of serum ALT,AST,TB,MDA and SOD(P

OBJECTIVEIntends to create mathematical model and analysis of correlation between Chinese medicinal characteristics and immunoregulatory activity based on literature informatics.

METHODThe numbers of the Chinese medicines with immune effects were worked out within the framework of "The China Pharmacopeia" of 2005 edition, from the literature publicized since 1980. The correlation and mathematical model were figured out between Chinese medicinal characteristics including biological classification, different tastes, channel tropism as well as the parts used and immunoregulatory activity based on the statistical software SPSS.

RESULTThe results showed that the immunoregulatory activity was related to the five tastes of Chinese medicines, and the pungent medicines had less immune effect. The Chinese medicines of underground parts had more immune effect compared with other parts of the medicine. Medicines acting upon heart and kidneys were more powerful as for the immune effects (P <0.05). The coincidence was 74.7% between mathematical computing and original classification.

CONCLUSIONThere are correlations,between Chinese medicinal characteristics and immunoregulatory activity. The mathematical model based on these results can be used for immunopharmacology.

OBJECTIVETo observe the expression of urotensin II (UII) on the lung of patients with pulmonary hypertension (PH) with congenital heart disease and investigate the meaning of this phenomenon.

METHODThirty eight patients with CHD were divided into three groups according to pulmonary arterial systolic pressure (PASP) measured in cardiac catheterization and surgery: normal pulmonary pressure group (N group, PASP < 30 mm Hg, n = 10), mild PH group (M group, PASP ≥ 30 mm Hg, n = 15), severe or moderate PH group (S group, PASP ≥ 50 mm Hg, n = 13). The expression of UII protein and UII mRNA in pulmonary arterioles were measured separately by immunohistochemical (IHC) analysis and in situ hybridization (ISH) analysis.

RESULT(1) The results of UIIIHC staining: The UII protein expression of group M was higher than that of group N (20.22 ± 3.58 vs. 14.34 ± 2.18, P < 0.01), but less than group S (20.22 ± 3.58 vs. 28.92 ± 3.22, P < 0.05). (2) The results of UIIISH mRNA staining were similar to IHC staining, the A value of group M was higher than group N (12.51 ± 2.02 vs. 8.85 ± 1.41, P < 0.05), less than that of group S(12.51 ± 2.02 vs. 25.35 ± 4.33, P < 0.01). (3) Correlation study: there was a positive correlation between the A values of UIIIHC and pulmonary hypertension (r = 0.64, P < 0.01, n = 38), a positive correlation between the A values of UIIISH and pulmonary hypertension (r = 0.58, P < 0.01, n = 38).

CONCLUSIONThere was the expression of Urotensin II protein and mRNA in the lung of pulmonary hypertension patients with congenital heart disease, and these expression may involve the formation of pulmonary hypertension of congenital heart disease.
