?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 study the effect of nutritional nursing on improving blood lipid and blood glucose of pregnant women with abnormal glucose metabolism. Methods 84 pregnant women with abnormal glucose metabolism from May 2014 to December 2016, were randomly divided into two groups, the control group and the experimental group. The control group was given routine nursing intervention, including the choice of food and food guidance, and so on, according to the method of the diabetes food exchange , at the end of pregnancy, patients were followed up. The experimental group was given strict nutrition nursing intervention, on the basis of the control group. Results The blood glucose levels of pregnant women were significantly higher than in the end of pregnancy, and fasting glucose of mid pregnancy in the control group was significantly lower than the late pregnancy, in the aspect of blood glucose of 2hafter meal and the fasting blood glucose in the middle of pregnancy. Level of lipid triglycerides in the experimental group and the control group were obviously lower than the late pregnancywith statistical significance (P<0.05),and there was no significant difference in high-density lipoprotein cholesterol (hdl-c), low density lipoprotein cholesterol (hdl-c) and total cholesterol levels in mid and late pregnancy between the experimental group and the control group . Conclusion Lipid metabolism disorder is mainly showed as triglycerides in pregnant women with abnormal glucose metabolism, nutritional nursing intervention could effectively control blood sugar levels in pregnant women with abnormal glucose metabolism, without obvious effect on improving blood lipid, and is worthy of application.

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.

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 detect the mRNA and protein expression of interferon-inducible transmembrane protein-1 (IFITM1) in Peutz-Jeghers syndrome (PJS) and investigate the role of IFITM1 in the occurrence, development and carcinogenesis of PJS polyps.

METHODSReverse transcription-PCR was employed to detect the mRNA expression of IFITM1 in 16 PJS polyp samples, adenomatous polyp tissues, colon adenocarcinoma samples, and normal intestinal mucosal tissues. The protein expression and localization of IFITM1 in these tissues (32 cases for each) were detected with immunohistochemical (IHC) staining.

RESULTSThe IFITM1 mRNA expression was detected in all these tissues, and the expression intensity increased in the order of normal intestinal mucosa, PJS polyp, adenomatous polyp, and colon adenocarcinoma (F=92.704, P=0.000). IHC revealed that IFITM1 protein was localized mainly on the cell membrane and in the cytoplasm, with increased expression intensity in the same order as its mRNA and showing significant differences between the tissues by several rank-sum test (Kruskal-Wallis H, chi(2)=37.036, p=0.000).

CONCLUSIONThe expression level of IFITM1 is associated with the progression of the carcinogenetic process in PJS polyp, and can be used as a sensitive biomarker for diagnosis and prognostic evaluation of PJS.

OBJECTIVETo investigate whether breastfeeding can reduce the risk of childhood overweight in the offspring of mothers with gestational diabetes mellitus (GDM).

METHODSFollow-up was performed on 1189 offspring of mothers with GDM between January 2003 and December 2009. The influence of the manner and duration of breastfeeding between 0 to 3 months after birth on the risk of childhood overweight in the offspring of mothers with GDM was analyzed by logistic regression.

RESULTSAfter correcting confounding factors such as pre-pregnancy BMI, gestational weight gain, gestational blood sugar, sex, birth weight, age and farther's body weight, it was found that the risk of childhood overweight in the offspring who received exclusive breastfeeding during the first 3 months after birth was lower than in the artificial feeding group (OR: 0.479, 95%CI: 0.256-0.897). Offspring who were breastfed for 0 to 3 months, 4 to 6 months and over 6 months had a lower risk of childhood overweight than the artificial feeding group (OR: 0.456, 95%CI: 0.233-0.827; OR: 0.29, 95%CI: 0.103-0.817; OR: 0.534, 95%CI: 0.280-0.970), offspring who were breastfed for 4 to 6 months had a lower risk of childhood overweight than those who were breastfed for 0 to 3 months (OR: 0.372, 95%CI: 0.129-0.874), and offspring who were breastfed for more than 6 months did not show significantly lower risk of overweight than those who were breastfed for less than 6 months (OR: 0.769, 95%CI: 0.470-1.258).

CONCLUSIONSWithin 3 months of birth, breastfeeding, especially exclusively, may reduce the risk of childhood overweight in the offspring of mothers with GDM. Within 6 months of birth, the risk of childhood overweight decreases as the duration of breastfeeding increases, but prolonging the duration of breastfeeding cannot necessarily reduce the risk of childhood overweight after postnatal six months.

OBJECTIVETo investigate the relationship between the thiopurine methytransferase (TPMT) gene polymorphisms and its enzymatic activity, and to clarify the significance of TPMT activity and gene polymorphisms on individualized therapy with thiopurines.

METHODSThe TPMT activity and gene polymorphisms were determined in an unrelated population of 250 Chinese healthy blood donors, 100 cords blood and 280 patients with acute leukemia. The TPMT genotyping assay was based on polymerase chain reaction (PCR), restriction digestion of PCR products, denaturing high-performance liquid chromatography (DHPLC) and SNaPshot sequencing and direct DNA sequencing in the TPMT exon 5 (G238C), TPMT exon7 (G460A) and TPMTexon10 (A719G). Erythrocyte TPMT activity was measured by high-performance liquid chromatography (HPLC).

RESULTSThe frequency of TPMT polymorphism in 250 Chinese healthy blood donors, 100 cords blood and 280 patients with acute leukemia was low (3.5%), and all the varied alleles were TPMT* 3C (exon 10A719G). All of them were TPMT* 1/TPMT* 3C heterozygote. The TPMT activity was between 6 and 12 U. The activity in 95.1% was more than 12 U (13 - 32 U), while the activity in others (4.9%) was 6 - 12 U. TPMT activity and genotype were concordant. Of 630 subjects evaluated, TPMT activity of heterozygous individuals in Chinese healthy blood donors, cords blood and acute leukemia patients were 9.1 U, 9.3 U and 9.07 U, respectively, significantly lower than that in general population (17.6 U, 17.67 U and 18.6 U, respectively). In the samples analyzed, ten subjects with heterozygous phenotypes (6/15 acute leukemia children and 4/16 healthy blood donors and cords blood) did not have TPMT* 2, TPMT* 3A or TPMT* 3C. Therefore, other factors may affect on TPMT activity.

CONCLUSIONTPMT gene polymorphisms and its activity were concordant. The heterozygotes had low TPMT activity. Therefore, detection of TPMT genotype and its activity is useful. These findings hold a promise of improving the safety and efficacy of thiopurines therapy.
