?AlM: To evaluate the clinical efficacy of posterior continuous curvilinear capsulorhexis ( PCCC ) combined with anterior vitrectomy in preventing posterior capsule opacification of congenital cataract surgery.
?METHODS:Postoperative clinical follow-up data of 82 cases ( 87 eyes ) with congenital cataract treated in Eye Center of our hospital from January 2011 to August 2014 were retrospectively analyzed. The patients were divided into the surgical control group ( 38 cases, 40 eyes, recieved phacoemulsification + PCCC ) and the study group ( 44 cases, 47 eyes, accepted phacoemulsification+ PCCC + anterior vitrectomy). The incidence of central optic axis opaque and postoperative visual acuity distribution were recorded at 1a follow - up. lntraoperative and postoperative complications were observed.
?RESULTS:The rate of central optic axis opaque grade 0 in control group was 37. 5%, compared to 76. 6% in study groups. The opacity distribution ratio of grade 1,2,3 and 4 in study group were lower than that of control group, and the central optic axis opacity distribution ratio in study group was significantly better than that of control group (P<0. 05). The 19 eyes(47. 5%) of visual acuity testing ≤0. 5 in control group , was higher than the 7 eyes(14. 89%) of that in the study group, The 21 eyes (52. 5%) of visual acuity testing >0. 5 in control group was lower than the 40 eyes ( 85. 11%) of that in study group. The visual acuity between two groups has statistical significance difference after 1a follow-up ( P<0. 05 ) , and the visual acuity in study group was significantly better than that in the control group. The postoperative intraocular pressure at 1mo and 1a follow-up was lower than before operation in two groups ( P<0. 05), but there was no significant difference between two groups in intraocular pressure (P<0. 05).
?CONCLUSlON: Combination of phacoemulsification, PCCC and anterior vitrectomy presents reliable clinical effects on postoperative central optic axis opacity distribution ratio and visual acuity, and it should be adopted to prevent the occurrence of posterior capsule opacification.

OBJECTIVETo observe monocyte (Mo) development in wild type C57BL/6 mice and apoE gene knockout (apoE(-/-)) mice, and to evaluate the immuno-regulatory effect of Huanglian Jiedu Decoction (HJD) on peripheral Mo development in apoE(-/-) mice.

METHODSFour, 8, 12, and 16 weeks old female C57BL/6 mice were set up as control groups of different ages, while 4, 8, 12, and 16 weeks old female apoE(-/-) mice were set up as hyperlipidemia groups of different ages. Four-week old female C57BL/6 mice were recruited as a blank group. Four-week old female apoE(-/-) mice were randomly divided into the control group, the Western medicine group, and the Chinese medicine group by paired comparison, 5 in each group. Equivalent clinical dose was administered to mice according to body weight. Mice in the Western medicine group were administered with Atrovastatin at the daily dose of 10 mg/kg by gastrogavage, while those in the Chinese medicine group were administered with HJD at the daily dose of 5 g/kg by gastrogavage. Body weight was detected each week. After 4 weeks blood lipids levels (such as TG, TC, LDL-C, and HDL-C), and the proportions of Mo and Ly6c(hi) were detected.

RESULTSCompared with 4-week-old homogenic mice, the proportion of Mo decreased in 16-week-old C57BL/6 mice (P < 0.05). Levels of TC and TG, and the proportion of Ly6c(hi) subtype increased, but the proportion of Mo de- creased in 8-week-old apoE(-/-) mice (P <0. 05). Levels of TC, TG, and LDL-C increased in 12-week-old apoE(-/-) mice (P < 0.05). Levels of TC, TG, LDL-C, and HDL-C increased in 16-week-old apoE(-/-) mice (P < 0.05, P < 0.01). Compared with 8-week-old homogenic mice, the proportion of Mo decreased in 16-week-old C57BL/6 mice (P < 0.05); levels of TC and LDL-C increased in 12-week-old apoE(-/-) mice (P < 0.05); levels of TC and HDL-C increased in 16-week-old apoE(-/-) mice (P < 0.05, P < 0.01). Compared with C57BL/6 mice of the same age, TC and TG increased, HDL-C decreased (P < 0.01) in 4-and 8-week-old apoE(-/-) mice (P < 0.01); levels of TC, TG, LDL-C increased, and HDL-C level decreased in 12- and 16-week-old apoE(-/-) mice (P < 0.05, P < 0.01); the proportion of Mo increased in 4-week-old apoE(-/-) mice (P < 0.05); proportions of Mo and Ly6c(hi) increased in 8-week-old apoE(-/-) mice (P < 0.05). Compared with the blank control group, levels of TC, TG, and LDL-C, proportions of Mo and Ly6c(hi) increased (P < 0.01, P < 0.05), but HDL-C level decreased (P <0. 01) in the control group after intervention. Compared with the control group, body weight gained less in the Western medicine group and the Chinese medicine group (P < 0.05); the proportion of Ly6c(hi) subtype decreased in the Chinese medicine group (P < 0.05).

CONCLUSIONSIn development process blood lipids levels in apoE(-/-) mice are not only associated with age. Blood lipids levels induced growth changes in natural immune system are also correlated with age. In early stage of lipids development HJD intervention could correct this special immune disorder in apoE(-/-) mice.

Objective To obtain the elasticity value of solid breast lesions with supersonic shear wave elastrography (SWE) and apply the binary Logistic regression in order to evaluate the value of SWE in differential diagnosis of benign and malignant breast lesions. Methods SWE quantitative elastography was preformed in 91 breast lesions of 91 patients in Zhenghai Longsai Hospital to obtain the maximum and mean elasticity value (Emax, Emean). And receiver operating characteristic (ROC) curves were used to assess the diagnostic performance. A Logistic regression for the gray scale ultrasound and the elastic modulus was conducted with multiple variables including Emax, Emean, border, echo, form, calcification. Results Pathological examination showed 73 benign lesions and 18 malignant lesions. Emax and Emean of malignant lesions were obviously higher than those of benign lesions [(99.73±41.15) kPa vs (38.59±14.28) kPa, (61.45±24.88) kPa vs (23.46±11.44) kPa, t=-15.05,-14.12, both P=0.000]. The area under the ROC curve of Emax and Emean were 0.932 and 0.915. Taking 63.70 kPa as the threshold of Emax, the sensitivity was 77.8%and the speciifcity was 97.3%. Then taking 44.22 kPa as the threshold of Emean, the sensitivity was 83.3%and the speciifcity was 94.5%. The results of Logistic regression analysis showed:the 3 most effective variables were Emax, border of the lesions and Emean. Conclusions The multivariate analysis model of binary Logistic regression can select the valuable indexes of differential diagnosis of benign and malignant breast lesions. SWE plays an important role in differentiating benign and malignant lesions and it is valuable in clinical practice.

The aim of the present study was to gain an insight into the thiopurine methytransferase (TPMT) genotyping assay, which was based on polymerase chain reaction (PCR), allele-specific PCR, restriction digestion of PCR products, denaturing high-performance liquid chromatography (DHPLC) and SNaPshot sequencing and in combination with direct DNA sequencing. Among the f our methods to test TPMT genetic SNPs based on PCR, allele specific PCR was not able to differentiate wild type from varied type. BsiYI, MwoI and AccI to digest PCR products were used so that SNP in TPMT exon 5, 7 and 10 tested. It showed that there were no differences between the results of digestion of PCR products and those of DNA sequence analysis. Therefore, this method was reliable. But some other methods were still needed to look for a compensation, because no restriction map changing resulted from the 2 SNPs in TPMT promotor was found. As to the results of DHPLC, those for the screening of TPMT exon-5 and -10 for SNPs were the same as restriction analysis of PCR products and direct DNA sequencing. But the variation of the heterozygotes in exon-7 was high, which was different from the results of direct DNA sequencing. After changing the Tm of DNA step by step, It was found that all the samples showed single peak when the temperature was 54 degrees C. But this result was unbelievable because a heterozygote in exon 7 as positive control could not be found. Therefore, it was necessary to test the sensitivity and accuracy of DHPLC, though DHPLC could be used as an effective method of SNPs screening. The results of the SNaPshot sequencing were also same as those of restriction analysis of PCR products and direct DNA sequencing. And the results showed that the bases of TPMT promoter -91 and -168 were G, instead of A and T. The results of the four methods to detect TPMT genetic SNPs based on PCR showed that SNPs analysis technique should be a combination of the techniques above-mentioned. One technique alone could not satisfy the need in clinics and research. The compensation of each other was very important.

OBJECTIVETo observe therapeutic effect of orientation taping magnetic granules at auricular points and Neiguan (PC 6) on motion sickness.

METHODSAll 200 cases of motion sickness were divided into a treatment group (n = 102) and a control group (n = 98). The treatment group were treated with orientation taping magnetic granules at auricular points and Neiguan (PC 6), and the control group with oral administration of theohydramine.

RESULTSThere was a significant difference between the two groups in the total effective rate (P < 0.05), and clinical symptoms disappeared more rapidly in the treatment group as compared with the control group (P < 0.05). The therapeutic effect in the mild and moderate patients of the treatment group was better than that of the control group, and there was no significant difference in the therapeutic effect for the severe patients between the two groups. In the treatment group, the therapeutic effect of the mild patient was the best, the moderate patient was next and the severe patient was the worst, with a very significant difference (P < 0.005).

CONCLUSIONOrientation Taping magnetic granules at auricular points and Neiguan (PC 6) has an obvious therapeutic effect on motion sickness, with less adverse reactions.

OBJECTIVETo investigate the effect of Compound Qingqin Liquid (CQL) on the expression level of angiotensin II (Ang II) and COX-2 mRNA transcription and protein expression in the renal tissue of rats with uric acid nephropathy.

METHODSSD rats were randomly divided into the blank control group, the model group, the positive drug group, the high, moderate, and low dose CQL group according to number randomization principle. The model was established by gastrogavage of adenine, accompanied with yeast feeding. Distilled water was given by gastrogavage to rats in the blank control group and the model group. Allopurinol at the daily dose of 9.33 mg/kg was given by gastrogavage to rats of the positive control group. CQL at the daily dose of 3.77 g/kg, 1.89 g/kg, and 0.09 g/kg was respectively given by gastrogavage to rats in the high, moderate, and low dose CQL groups. All treatment lasted for 6 weeks. Rats were randomly divided at week 4 (3 in the blank control group, and 6 in the rest groups), and the rest rats were killed at week 6. The renal tissue was extracted. The expression level of Ang II and COX-2 mRNA transcription were detected by RT-PCR. The expression level of Ang II was detected by ELISA. The expression level of COX-2 protein was detected by Western blot and immunohistochemical assay.

RESULTSCompared with the blank control group, except the mRNA expression of Ang II at week 4, the mRNA and protein expression of Ang II and COX-2 obviously increased at week 4 and 6 in the model group (P < 0.01, P < 0.05). The COX-2 protein expression at week 4 was obviously lower in the high and moderate dose CQL groups than in the model group and the low dose CQL group (P < 0.05); the average integral of optical density value was obviously lower in the positive control group than in the model group. Except the mRNA expression of Ang II in the high dose CQL group at week 6, the mRNA and protein expression of Ang II obviously decreased in the positive control group and each dose CQL group (P < 0.01, P < 0.05). Of them, the effects were better in the high and moderate dose CQL groups than in the positive control group and the low dose CQL group (P < 0.05, P < 0.01). Besides, the mRNA expression of COX-2, the average integral of optical density value were obviously lower in the positive control group and each dose CQL group than in the model group (P < 0.05). The protein expression of COX-2 was obviously lower in the high and moderate dose CQL groups than in the model group (P < 0.05). Of them, the mRNA expression of COX-2 was better in the moderate dose CQL group than in the positive control group (P < 0.05); the protein expression of COX-2 was better in the high dose CQL group than in the low dose CQL group (P < 0.05).

CONCLUSIONCQL was capable of lowering the expression level of Ang II, COX-2 mRNA transcription and protein expression, thus suppressing the inflammatory pathological injury of the renal tissue.

OBJECTIVEFor the purpose of clarifying the influence of thiopurine methyltransferase (TPMT) gene single nucleotide polymorphisms (SNPs) on the efficacy of thiopurines and risk for its toxicity and therefore improving the safety and efficacy of thiopurines, the authors investigated TPMT genotype in acute leukemia in children who were intolerant to the treatment with 6-mercap topurine (6-MP).

METHODSTPMT genotype was determined in an unrelated population of 250 Chinese healthy blood donors and 280 children with acute leukemia. TPMT genotyping assay was based on polymerase chain reaction (PCR), restriction digestion of PCR products, denaturing high-performance liquid chromatography (DHPLC) and direct DNA sequencing in the TPMT * 2 (G238C), TPMT * 3A (G460A, A719G) and TPMT * 3C (A719G).

RESULTSThere were 10 TPMT * 1/TPMT * 3C heterozygotes in 280 children. The frequency of the polymorphism was 3.6%. All the involved alleles were TPMT * 3C. Of the 160 children acute leukemia evaluated, 45 (26%) were intolerant to 6-MP. Presentations included hepatotoxicity and hematological toxicity. Six out of 45 children were heterozygous, while the other 39 were wild type homozygous. Before dosage adjustments for thiopurine, the hematologic toxicity and hepatotoxicity in TPMT heterozygous individuals occurred more frequently than in homozygous. Therefore, cases of TPMT heterozygotes experienced more missed doses of 6-MP.

CONCLUSIONSTPMT genotype is associated with tolerance in acute leukemia in children. The heterozygote individuals have low TPMT activity. Therefore the frequencies of hemtopoietic toxicity and hepatoxicity are high after using 6-MP. Detection of SNPs in the TPMT genes is useful in identifying children before administration of 6-MP.
