The ACE genotype of 28 children (10 children complicated coronary dilataltion) with KD and 35 healthy controls were detected by polymerase chain reaction (PCR), and ACE concentration in blood serum was measured by ultraviolet-spectrophotometer assay.Results 1.The ACE concentration was significantly higher in KD group than that in healthy control group(P

OBJECTIVETo investigate the functional and metabolic alterations in cultured insulin resistant ovary model in vitro, and to observe the effect of berberine (Ber, a Chinese medical monomer) in improving insulin resistance (IR).

METHODSOvary of mouse was cultured in vitro and treated by dexamethasone (Dex) to induce IR for establishing IR model ovary. The functional alteration in model ovary was assessed through detecting glucose and hormone levels in medium using RT-PCR, meanwhile, the expression of key molecules in insulin signal and steroid synthetic pathway were detected, and condition of IR improved by berberine was evaluated also.

RESULTS(1) The model ovary was made by Dex in dose- and acting time-dependent manner. After being treated by 300 nmol/L Dex for 48 h, the glucose uptake of ovary reduced from 9.05 +/- 0.75 mg/g to 2.48 +/- 0.29 mg/g (P < 0.05); it further decreased (from 9.59 +/- 1.74 mg/g to 1.94 +/- 0.19 mg/g, P < 0.01) under the stimulation of insulin, which proved that the IR model ovary was made successfully. Berberine significantly increased the glucose uptake of model ovaries (1.89 +/- 0.33 mg/g to 13.95 +/- 3.30 mg/g, P < 0.05). (2) As compared with control group, levels of testosterone (T) and androstenedione (A2) were higher, and levels of progesterone (P) and 17-hydroxyprogesterone (17-OHP) were lower significantly in the model. Berberine reversed the alternations of T, A2 and 17-OHP levels, but did not influence the level of P. (3) RT-PCR showed that the mRNA expressions of cytochrome 17-hydroxylase (CYP17) and mini-chromosome maintenance protein-2 (MCM-2) elevated, but extracellular regulated protein-1 (ERK-1), protein kinase B (AKT-2) and glycogen synthase kinase-3 (GSK-3beta) lowered in the medium after Dex inducing. Berberine treatment restored these molecular index obviously.

CONCLUSIONS(1) Dex could induce IR in mouse ovary, which might enhance the androgenic synthesis. (2) Berberine could alleviate the degree of IR and the androgen synthesis, indicating that the Chinese sensitizing agents has favorable therapeutic effect for the treatment of polycystic ovaries.

Objective To explore the sensitivity and accuracy of directly sequenced core and non-structrural protein (NS)5B regions for hepatitis C virus (HCV)genotyping.Methods Fifty-one serum samples from chronic hepatitis C patients were collected in the study.Reverse transcription-polymerase chain reaction was used to amplify core and NS5B regions.Genotypes or subtypes were determined by the phylogenetic analysis of directly sequenced core and NS5B regions.Results Among the 51 samples,49 (96.1 %)were successfully typed by phylogenetic analysis of directly sequenced core region.There were overall five genotypes determined in the area,including 1b (61 .2%,30/49 ),2a (20.4%,10/49 ),2b (2.0%,1/49),3a (4.1 %,2/49 )and 6a (12.2%,6/49 ).The positive rate of HCV genotying was 88.2% (45/51 )on the basis of NS5B region.HCV genotypes 1b,2a,2b,3a and 6a were found in 62.2% (28/45),20.0% (9/45 ),2.2% (1/45 ),4.4% (2/45 )and 11 .1 % (5/45 )of the patients, respectively.Conclusion The HCV genotyping based on core regions,compared with that based on NS5B,shows the advantages of primer design,amplification efficiency and accuracy,suggesting that it has the priority to be used in the epidemiological and clinical study of HCV genotyping.

AIM: To observe the effect of Ahmed glaucoma valve implantation intravitreal bevacizumab in the treatment of neovascular glaucoma ( NVG) .
METHODS:Twenty-two cases (22 eyes) who presented with NVG were first treated with intravitreal bevacizumab 0. 1mL ( 2. 5mg ), then with Ahmed glaucoma valve implantation after regression of iris neovessels. Cases were followed - up for 6 - 36 ( mean 24 ) mo with observation on visual acuity, IOP control, regression of iris neovessels, and complications during or after surgery.
RESULTS: Iris neovessels was regressed in different degree after injection within 1wk in 22 eyes. At final follow-up, the IOP of 18 eyes were all less than 21mmHg without any drugs and of 3 eyes with 1-3 kinds of anti-glaucoma drugs after combined Ahmed glaucoma valve implantation. The IOP of one eye was controlled after cryotherapy. The mean IOP dropped from 45. 36 ±8.13mmHg preoperatively to 15. 59 ± 3. 21mmHg postoperatively. IOP reduction was statistically significance between preoperative and postoperative ( P<0. 05) at final follow-up. Visual acuity was improved in 9 eyes (41%) and was no changed in 13 eyes. No serious complications were observed during or after intravitreous bevacizumab injection and Ahmed glaucoma valve implantation.
CONCLUSION: Ahmed glaucoma valve implantation and intravitreal bevacizumab in the treatment of NVG is useful and safe. It improves the success rate of surgery and preserves visual function, furthermore its complications are less.

AlM:To observe the relationship between axial length and complications of phacoemulsification with intraocular lens ( lOL) implantation in high axial myopia eyes and normal axis eyes.
METHODS: A retrospective review of 843 consecutive patients ( 1 042 eyes ) of cataract extraction with phacoemulsification and lOL implantation in our hospital from February 2012 to February 2013 was performed. The patients were divided into two groups according to the axial length: 853 eyes were in normal axis group ( 21-24mm) and 189 eyes were in high axial myopia group (≥26mm). The two groups were compared regarding surgical complications, such as vitreous loss, posterior capsular rupture, nucleolus drop, and abnormal location of lOL.
RESULTS:Age was a risk factor in both groups. There was positive correlation between age and surgical complications, and between axial length and surgical complications, especially for complications with posterior capsular rupture and vitreous loss.
CONCLUSlON:As the results illustrate, in this survey, age and high axial lengthare statistically significant risk factors for incidence of complications of phacoemulsification. Anticipation of these complications and also preparation and prophylactic measures may decrease incidence of these complications.

Objective To observe the different effects of iodine excess on inducing two strain mice thyroiditis. Methods NOD and Balb/c mice, each having 14 mice, were divided into NaI and control group. The mice were given 0.05% NaI water for 8 weeks in NaI group. RIA and ELISA were used respectively to detect TT4, TgAb, TPOAb and TSH level in serum. Morphology changes of thyroid and apoptosis of thyrocytes stained by immunohistochemistry were observed under light microscope. Lymphocytic proliferation of cervical lymph node and spleen to responding to Tg were detected by MTr method. Results After intake of iodine water for 8 weeks, NOD and Balb/c mice showed relative quality of thyroid in Nal group[(104.83±14.52), (155.79±20.77)mg/kg]obviously increased compared with control group[(71.80±20.42), (105.15±21.98)mg/kg, t values:-3.293,-4.429, all P< 0.01)], enlarged follicular lumen with colloid accumulation were observed in thyroid. Serum level of TT4 in Nal group [(29.52±4.42), (19.53± 2.35)nmol/L]to control group[33.40±5.38), (23.47±6.22)nmol/L]of NOD and Balb/c mice showed a decreasing tendency(t values: 1.374,1.567, all P > 0.05). TSH of Nal group showed an increasing tendency in Balb/c mice[(4.14±1.71)μg/L, compared with control [(3.55±1.41)μg/L, t values:-0.705, P > 0.05]and obviously increased in NOD mice [(6.98±0.66)μg/L, compared with control[(555±056)μg/L, t values:-3.562, P< 0.01], but no change of TgAb and TPOAb level in Nal group(1281,1364 cpm, 2.50×103, 0.14×103U/L were observed, compared with control(1297,1220 cpm, 3.17×103,0.03×103 U/L; Zvalues:-0.081,-0.703, -0.244,-1.293, all P > 0.05). In NOD mice NaI group, apoptosis of thyrocytes was more intense than Balb/c mice, obvious infiltration of lymphoeytes, disorganization and focus fibrosis was seen in thyroid. The cell amount of NaI group increased in NOD mice lymph node and spleen cells[(1.100±0.014), (1.076±0.033)]were more than that in the control group [(0.993±0.011), (1.005±0.003), t value:-11.672,-4.314, P < 0.01). Conclusions Iodine leads to enlargement of thyroid and malfunction of thyroid in Balb/c mice. Besides, NOD mice have generate inflammatory reaction in thyroid and produced sensitized lymphocytes to Tg. Iodine excess can induce NOD mice to occur autoimmune thyroiditis.
