OBJECTIVE: Intraocular lens are applied in trigeminal operations of cataract extraction and comeal transplantation, and the selection of artificial lens is modified. This paper evaluated the application of colodzed polymethyl methacrylate (PMMA) intraocular lens in interlaced non-phacoemulsification cataract extraction with intraocular lens implantation and keratoplasty (trigeminal operation).METHODS: A computer-based online search of CNKI (200312007) and Medline database (1974/2004) was performed for related articles with the key words "colorized intraocular lens, corneal transplantation, cataract, combination operation" in Chinese and "PMMA intraocular lens, cataract extraction, corneal transplantation" in English. Articles related to PMMA intraocular lens in cataract and corneal transplantation trigeminal operation was selected. Meta analysis and repetitive articles were excluded. A total of 11 articles were included and summarized.RESULTS: A total of 21 cases (21 eyes) of corneal leukoma and cataract caused by various trauma or ophthalmopathy underwent colorized PMMA intraocular lens implantation. During the follow-up for 10 months, visual acuities of naked eyes in 92% cases were significantly improved. Two weeks after operations, visual acuities of 9 cases (42.9%) were over 4.7, 10 cases over 4.5, and 2 cases (9.5%) over 4.0. At days 7 to 14 after operation, corneal grafts of 21 cases were completely transparent; 10 months after operation, corneal grafts of 16 cases were completely transparent, 3 cases were semitransparent, and 2 cases were turbid, who underwent second penetrable corneal transplantation.CONCLUSION: The application of colodzed PMMA intraocular lens in penetrable corneal transplantation combined cataract extraction can cure the refracting media turbidity of forepart eye. Compared with traditional operations, trigeminal operation reduces complications, increases safety and improves visual acuity.

Objective The report was focused on polycystic ovary syndrome(PCOS) in female adolescents related to homosexual precocious puberty,and the new awareness of its influence on long-term health of homosexual precocious girls.Methods A girl with idiopathic central precocious puberty (ICPP) but diagnosed as PCOS in adolescence was reported and the data were reviewed.Results A girl was diagnosed as ICPP when she was near 8 years old with obesity,but without hyperinsulinemia,then she received the treatment of a 3.75 mg dose gonadotropin hormone analogues (GnRHa) every 28 days.Her gonads development was under control while her growth was arrested.Growth hormone(GH) injection started at 13 months.She stopped all medications when finished GH and GnRHa treatment for 12 months and 25 months.She went to see doctors again because of no menarche after discontinuing medication for nearly 2 years.She appeared obese and acne,hirsutism,athanens negricans and purple purple striae on the skin.Hyperinsulinemia and hypertestosterone were demonstrated.Pelvic B ultrasonography showed polycystic ovary,and she was diagnosed as PCOS.She was ordered to lose weight and to take metformin.And adrenocorticotropic hormone stimulating test was done,and B ultrasonography again ruled out atypical congenital adrenal hyperplasia and tumor of adrenal gland.She got her menarche 1 month later.Twelve months after the PCOS diagnosis and treatment,she had 4 menses,her insulin level decreased,glucose tolerance and her serum testosterone level turned normal.At the same time,the form of ovarian and follicular was significantly reduced.After taking mefformin for 20 months,her height and weight did not change,her menstrual was regular every 35-40 days,each time lasting about 7 days.She was followed up.We also reviewed literatures and learnt that precocious puberty might not be a benign situation and it might have an intrinsic relation to obesity,precocious puberty and PCOS.It might be the cofactors for causing PP and PCOS that accessed luteinizing hormone(LH) secretion and disorder of hypothalamus pituitary gonad(HPG) axis except obesity with hyperinsulinemia.Reported pubertas praecox in childhood developed to PCOS at 30％ with high prevalence of obesity.GnRHa suppressive therapy might relate to PCOS and had disputation for improving final height.There were fewer investigations on adolescent PCOS,and no consensus guideline on it in China.Conclusions Girls with ICPP may develop to PCOS some time later.The clinical features of the reported girl and the knowledge from literatures support the hypothesis that inner relationship between the CPP and the PCOS.The LH high secretion and disorder of HPG axis may be the causes of them; LH treatment on suppressing obesity should be cautious during treatment.The benefit and risk from GnRHa treatment should be evaluated thoroughly.Further clinical research should be conducted on adolescent PCOS.

Aim To investigate the regulatory effects of baicalin on apoptosis induced by virus H1 N1 in hu-man pulmonary carcinoma cell A549 . Methods The chips were used to screen the RNA samples in virus-in-fected A549 cells. Differentially expressed genes were selected in the pathway of apoptosis. The mRNA ex-pressions of caspase-3 and -8 were verified by Real-Time PCR. Results With the DNA microarray, the functions of differentially expressed genes involved in apoptosis biological pathways were analyzed by Kyoto Encyclopedia of Genes and Genomes ( KEGG ) Path-way databases. caspase-3, -7, -8, -10, TRAIL, MYD88 , IL1 A and IL1 B were up-regulated in virus-in-fected group. Oseltamivir could down-regulate gene ex-pressions of caspase-3 ,-4 and-8 . High-dose of baica-lin could down-regulate gene expressions of caspase-3 ,-4,-6 and -8. Except gene expressions of above, low-dose of baicalin could also down-regulate gene expres-sions of IL1RAP and Cn. Real-Time PCR experiments showed that baicalin could significantly decrease mR-NA expression of caspase-3 , -4 , -6 , -8 , IL1 RAP and Cn ( P < 0. 01 ) , compared with the virus-infected group. The results also figured that the interference ef-ficacy of low-dose baicalin was better than that of high-doses. As expected, real-time PCR data were in good agreement with the microarray assay. Conclusions Baicalin can be detected in their suppression effect of caspase-3,-4,-6, and -8 mRNA expression, so it re-sists against the apoptosis to fight against influenza vi-rus in vitro.

Objective To investigate the effects of ciprofloxacin on anastomotic stoma,small intestinal inflammation and fibrosis in interleukin-10 knock-out mice (mice model of Crohn′s disease (CD)) after ileocaecal resection.Methods Twelve interleukin-10 knockout male C3H/HeJBir mice were evenly divided into control group and ciprofloxacin group.The mice model was established with ileocaecal resection and ileocolostomy.There was no intervention in control group.Ciprofloxacin (50 mg/kg per day)was orally administrated in ciprofloxacin group for four weeks.All the mice were executed.The intestine around anastomotic stoma was taken for hematoxylin-eosin (HE)and Sirius red staining and histological scoring.The level of interferon (IFN)-γand tumor growth factor (TGF)-βin intestine around anastomotic stoma and small intestine was detected by enzyme-linked immunosorbent assay (ELISA) method.The content of procollagen α1 was determined by real-time polymerase chain reaction.The data were analyzed by t test.Results The inflammatory reaction level of anastomotic stoma and small intestine in mice of ciprofloxacin group (2.50±0.55 and 1 .67±0.52)was significantly lower than those of control group (3.67±0.63 and 2.83±0.75 ,t=-8.273,-5 .188,both P <0.05 ).The IFN-γof anastomotic stoma and small intestine also significantly decreased ((0.72 ±0.22 )pg/mg vs (1 .76 ±0.43 )pg/mg, (0.23±0.12)pg/mg vs (0.78 ± 0.52 )pg/mg;t = - 7.354,- 5 .268,both P < 0.05).However, ciprofloxacin could not significantly decrease fibrosis in anastomotic stoma and small intestine of CD mice. There was no significant difference in the level of TGF-βcompared with control group.Conclusions The role of ciprofloxacin in improving inflammatory reation in anastomotic stoma of CD mice was limited. Maintenance therapy may be necessary to reduce the relapse of anastomotic stoma diseases.
