1.MiRNA and breast cancer metastasis
International Journal of Surgery 2010;37(1):46-48
Most deaths of breast cancer patients may be caused by the development of metastases. The latest research suggest that some miRNAs regulated gene expressions related with breast cancer metastasis at post-transcriptional level, which was closely related to invasion and metastasis of breast cancer. This review mainly dicussed the miRNA involved in regulation of invasion and metastasis of breast cancer and their mo-lecular mechanisms.

Objective To study the changes and correlations of the blood lipids, glucose and blood coagulation factors in the animal models and patients with lipodystrophia. Methods The models of hyperlipoidemia were set up in 30 rabbits, and 40 cases of the hyperlipoidemia and 40 cases of the healthy subjects randomly were enrolled in this study. Their blood lipids, glucose and coagulation factors were detected. Results The serum levels of TC,TG,LDL-C and Glu in the rabbit models and patients with hyperlipoidemia notably increased compared with controls(P0 05). HDL-C level increased in the rabbit models(P0 05). Conclusions The change of the blood lipids level in the rabbit models was different from that of the patients with hyperlipoidemia. But both may company the abnormality of carbohydrate metabolism, and hyperlipoidemia may affect the endogenous blood coagulation system to cause the blood to present the high coagulation.

Objective To study the effects of extensively hydrolyzed formula forvery/extremely low birth weight(VLBW/ELBW)infants.Methods From Jun.2013 to Oct.2015,78VLBW/ELBW infants admitted to our hospital within 12 hours of birth were randomly assigned into two groups:hydrolyzed protein formula feeding group ( hydrolyzed formula group) and preterm formula feeding group (control group). Infants with hospital stay <28 days were excluded. Prospective study was conducted between two groups comparing the duration of meconium discharge, the time required for total enteral feeding average hospital stay, feeding intolerance and physical growth and blood biochemical indices on the28thday.Results A total of 78 infants were enrolled,35 in hydrolyzed formula group and 43 in control group. Comparing with control group, feeding intolerance in hydrolyzed formula group was significantly lower ( 25. 7℅ vs. 72. 0℅) . The duration of meconium discharge [ ( 4. 9 ± 0. 8 ) d vs. (8. 8 ± 1. 6)d], the time required for total enteral feeding[(13. 4 ± 2. 0) d vs. (18. 9 ± 2. 6) d] and average hospital stay duration [ ( 33. 7 ± 5. 1 ) d vs. ( 41. 8 ± 6. 8 ) d ] was shorter in hydrolyzed formula group ( P<0. 05). The body length on the 28th day in hydrolyzed formula group was longer than control group[ (43. 8 ± 1. 2 ) cm vs. ( 42. 6 ± 2. 0 ) cm, P < 0. 05 ] . The concentration of serum albumin [ (32. 5 ± 3. 0 ) g/L vs. ( 30. 0 ± 4. 5 ) g/L ] and hemoglobin [ ( 112. 4 ± 11. 4 ) g/L vs. ( 106. 3 ± 13. 0) g/L] in hydrolyzed formula group were significantly higher than the control group( P<0. 05). No significant difference was found between the two groups regarding the time required returning to birth weight [(10. 9 ±2. 2)d vs. (10. 1 ±1. 7)d],body weight [(1759 ±107)g vs. (1627 ±435)g], head circumference[(30. 3 ± 1. 0)cm vs. (29. 7 ± 1. 6)cm] on the 28th day and the incidence of extrauterine growthretardation(EUGR)(40.0℅vs.44.1℅)atdischarge.Conclusions Comparing with preterm formula feeding, early feeding with extensively hydrolyzed formula can reduce the incidence of feeding intolerance on VLBW/ELBW infants. Extensively hydrolyzed formula also can accelerate meconium discharge, reduce hospital stay duration and the time required for total enteral feeding. But the growth of weight and head circumference on the 28th day and the incidence of EUGR at discharge were not altered by extensively hydrolyzed formula.

BACKGROUND:Diabetic cystopathy is one of the most common chronic diabetic complications. The establishment of animal models of diabetic cystopathy wil provide experimental animal platform for relevant research.
OBJECTIVE:To establish a guinea pig model of diabetic cystopathy and to evaluate its urodynamic characteristics.
METHODS:Fifty short-hair Britain female guinea pigs were randomly divided into two groups, 42 as the experiment group and the other 8 as the control group. The experiment group was intraperitoneal y injected with streptozotocin to induce diabetes. The control group received injection of blank citric acid buffered solution. Diabetic guinea pigs were detected by urinary dynamics test at 9 and 12 weeks. Diabetic guinea pigs were further assigned into diabetic cystopathy subgroup and compensated subgroup. The urodynamic parameters of three groups were compared.
RESULTS AND CONCLUSION:Twenty of 42 guinea pigs were successful y induced diabetes by the injection of streptozotocin. At 9 weeks after the injection, bladder function compensation was present in six diabetic guinea pigs while bladder function was decompensated in another three diabetic guinea pigs. At 12 weeks, bladder function compensation was present in one diabetic guinea pig, while another eight guinea pigs were confirmed with diabetic cystopathy (88.89%). In the diabetic cystopathy subgroup, the residual urine volume was increased (0.72±0.08) mL, maximal detrusor pressure was decreased (0.63±0.05) kPa, maximum bladder capacity was increased (2.01±0.05) mL, and bladder compliance was increased (0.34±0.04) mL/kPa. There were significant differences compared with the compensated subgroup and the control group (P<0.001). Diabetic cystopathy occurs at 12 weeks after diabetic models are successful y established in guinea pigs, and urodynamic changes are mainly the increase of residual urine volume.

Objective To investigate hepatic histological features and its influencing factors of HBeAg-negative chronic hepatitis B patients. Methods 134 HBeAg-negative chronic hepatitis B (CHB) patients who underwent percutaneous liver biopsy were recruited in this study. The liver biopsy sections were examined after routine haematoxylin-eosin (HE) staining, and silver staining for assessment of fibrosis. The activity of liver disease was assessed by using a modified Knodell numeric histology activity index (HAI). ALT level, HBV DNA load, HBV serological markers, HBV genotype were assessed with appropriate methods. t test or analysis of variance was used to compare means. Non-parametric was done by Kruskal-Wallis test. The correlation between liver pathological change and clinical factors was analyzed by multivariate linear regression. Results Of 134 HBeAg negative CHB patients, percentages of mild (HAI 4 ~ 8), moderate (HAI 9 ~ 12), and severe hepatitis (HAI 13 ~ 18) were 26.9%, 26.1%, and 47.0%, respectively. As for hepatic fibrosis, 18.7% and 81.3% of the patients had fibrosis score < 3 and ≥3, respectively. Multivariate regression analysis showed that ALT level and hepatic fibrosis were correlated to hepatic inflammation (t = 6.687,P < 0.01; t = 3.478, P < 0.01) while age and hepatic inflammation activity were influencing factors of hepatic fibrosis (t = 3.587, P < 0.01; t =7.136, P < 0.01). However, correlation is not significant between hepatic histological change and other factors, including gender, HBVDNA, HBV genotype and HBeAb status. Conclusions In this study, hepatic histological change tend to become worse in majority of HBeAg-negative chronic hepatitis B , especially in older patients and those with high ALT level.

To explore the clinical effect of alendronate combined with Jintiange capsules in the treatment of postmeno-pausal osteoporosis ( PMOP) . Methods:Ninety-eight cases of PMOP patients were randomly divided into three groups. The combina-tion treatment group (34 cases) was treated with alendronate tablets combined with Jintiange capsules, while the control group A (32 cases) and the control group B (32 cases) was respectively treated with alendronate tablets and Jintiange capsules, and the treatment course was six months. The changes of the clinical symptom score, bone mineral density ( BMD) , serum calcium, serum phosphorus, AKP, hepatorenal function and so on before and after the treatment were recorded. Results:After the six-month treatment, the clinical symptom score of the treatment group was much better than that in the two control groups(P<0. 05). BMD in the three groups was in-creased after the treatment(P<0. 05), and the increase in the treatment group was more notable than that in the two control groups(P<0. 05). Conclusion:Alendronate combined with Jintiange capsules can effectively improve BMD and relieve clinical symptoms in the patients with PMOP, which is worthy of promoted application.
