Breast cancer,with a high incidence rate,is one of the malignant cancers that threatens women health.Clinically,methods such as image examinations,needle aspiration cytology and pathology are used in its early diagnosis and treatment.However,the genetic heterogeneity of breast cancer has made patients in the same pathological stage respond differently to clinical treatment.So it ia important to formulate a molecular and genetictyping method which can accurately reflect the clinical types and prognoses of breast cancer.This paper reviews the research on gene chips applied to molecular and genetic typing methods of breast cancer and also discusses their applications in individualized treatment.typing method which can accurately reflect the clinical types and prognoses of breast cancer.This paper reviews the research on gene chips applied to molecular and genetic typing methods of breast cancer and also discusses their applications in individualized treatment.

It is a brief review of our research on the role of metallothioneins (MTs) in the occurrence and development of hepatocellular carcinoma (Hcc) in more than a decade,and the mechanism of prevention and treatment for Hcc in the field of TCM.It was found that MTs were required for the malignant proliferation of Hcc cells and their expressions significantly increased under different levels of stress.MTs may exert their effects on promoting proliferation via increasing ribosomal protein gene or other gene expressions.The over-expressions of MTs directly altered the balance of ions in the cell nucleus,and interacted on the genes promoting malignant proliferation.Hepatotoxicity and hepatic damage caused by DEN were reduced and relieved to different extents by the representative formula or constitute,which under the common therapeutic principle,by which MTs expressions were down-regulated as well.In conclusion,both effects above are important in the liver protection,inhibition of hyperplasia and carcinogenesis.

Objective To observe the effect of Wenxiao Decoction in treating the patients with carotid atherosclerostic (CAS) plaque and assess the safety. Methods Sixty patients with CAS plaque were randomly allocated to treatment group (33 cases) and control group (27 cases). The control group was given routine therapy, and the treatment group was given Wenxiao Decoction additionally. And they were further divided into half-year treatment group and half-year control group, 1-year treatment group and 1-year control group. Carotid artery color Doppler ultrasound and hepatorenal function were examined before and after treatment. Results Compared with the control groups after therapy, the average numbers of plaques, maximal plaque thickness, Crouse plaque integral were decreased both in 1-year and half-year treatment groups (P<0.05, P<0.01). The plaque stability of 1-year treatment group was better than that of half-year treatment group. The average numbers of plaques, plaques size and Crouse plaque integral increased in control groups after routine therapy (P<0.05, P<0.01). Bilateral common carotid artery diameter, intima-medial thickness (IMT) and hepatorenal function had no statistical difference between before and after treatment both in treatment and control groups (P>0.05). Conclusion Wenxiao Decoction is effective and safe in treatment of CAS plaque, and plaque stability is more obvious with the extension of treatment time.

AIM:To explore the effects of PPARγon the elevated level of reactive oxygen species ( ROS) in-duced by high glucose and its mechanism .METHODS:Human umbilical vein endothelial cells ( HUVECs) were cultured with DMEM containing high glucose (33 mmol/L D-glucose), and DMEM containing lower glucose (5.5 mmol/L D-glu-cose) was used as control .Superoxide anion and nitric oxide fluorescence probes were used to observe the effects of PPAR γagonist on ROS and NO productions in the HUVECs .The uncoupling protein 2 (UCP2) protein level in the HUVECs was detected by Western blotting .RESULTS:PPARγagonist pioglitazone inhibited the ROS generation and prevented the de-crease in NO level under high glucose condition , and these effects were reversed by pretreatment with PPARγantagonist GW9662.The results of Western blotting indicated that PPARγagonist pioglitazone up-regulated the UCP2 expression un-der high glucose condition , and this effect was also blocked by GW 9662.Inhibition of UCP2 by genipin attenuated the effect of pioglotazone on the ROS production .CONCLUSION: Activation of PPARγinhibits ROS generation under high glucose condition , and this effect may mediate by up-regulation of UCP2.

Objective To evaluate the impact of early enteral nutrition (EEN) compared with parenteral nutrition (PN) on patients after hepatectomy. Methods Seventy-eight patients undergoing liver resection were randomized prospectively into two groups: EEN group receiving early enteral nutrition (n=35) and PN group receiving parenteral nutrition (n=43). The patients in both groups received isocaloric and isonitrogenous nutritional formulas 24 h after operation and the formulas were stopped on postoperative day 7. The general conditions, liver function tests, clinical complications,and clinical nutritional variables at three time points that included preoperative phase, postoperative day 1 (POD 1) and postoperative day 8 (POD 8) were observed. Results No significant differences were found in length of hospital stay, liver function and clinical nutritional variables between the 2 groups. In the EEN group, the serum prealbumin level almost returned to the preoperative level on POD 8. The nutritional complication rate of the EEN group was increased significantly but it was milder than that of the PN group. The time of gut function recovery in the EEN group was shorter than that of the PN group. The costs of nutritional drugs showed a significant decrease in the EEN group.Conclusion Early enteral nutrition is safe, rational and effective in patients who have undergone hepatectomy. Early enteral nutrition is better than parenteral nutrition in promoting liver function recovery, liver protein synthesis, postoperative recovery of gut function and decreasing costs of nutritional drugs.

AlM:To explore treatment efficacy of the lower eyelid twitch muscle transposition surgery in senile entropion.METHODS:Fifty cases (86 eyes) of senile lower eyelid entropion patients underwent lower eyelid twitch muscle transposition correction surgery as the experimental group, and the other 42 cases (68 eyes) of senile lower eyelid entropion patients received orbicularis muscle shortening correction as controls group. The correction rate, double eyelid symmetry and overcorrection rate of patients were observed one week after surgery. The patients were followed up for 6~12mo to be observed the long-term recurrence rate, double eyelid symmetry and overcorrection rate.RESULTS: One week after operation, eyelid symmetry, overcorrection rate of experimental group and control group had significant difference (P<0. 05); After followed up for 6 ~12mo, eyelid symmetry, overcorrection rate of experimental group and control group had significant difference (P<0. 05). CONCLUSlON: Folding and orbicularis muscle shortening treatment of senile entropion was compared with the lower eyelid twitch muscle transposition surgery treatment of senile entropion, We can find that clinical results in double eyelid surgery symmetry and overcorrection rate are of obvious advantage.

ObjectiveTo study the correlation of urinary iodine and thyroid function in elderly men in Harbin,and to provide the basis for formulation of health measures for the elderly.MethodsSeventy five cases of clinically healthy elderly men were enrolled for check-up of urinary iodine,thyroid function and B-ultrasound in Geriatric Ward the Forth Affiliated Hospital of Harbin Medical University in 2010.The subjects of investigation were divided into iodine appropriate and iodine sufficient groups and thyroid function parameters and B-ultrasound results were compared.ResultsThe average age of the 75 cases of healthy elderly men was (79.07 ± 4.78) years old and the median of urinary iodine was 198.4 μg/L.There were 62.67％ (47/75) elderly males whose iodine nutritional status was appropriate,but there were still some individuals(6.67％,5/75) in the iodine excess state.The level of TSH of the iodine appropriate group [(1.91 ± 0.82)mU/L] was lower than that iodine sufficient group [(4.98 ±0.60)mU/L,t =12.58,P ＜ 0.05],while the level of FT3 of the iodine appropriate group[(4.71 ± 0.56)pmol/L]was higher than that iodine sufficient group[(3.31 ± 0.43)pmol/L,t =12.18,P ＜ 0.05].But the difference of FT4between the two groups [(14.91 ± 3.12),(14.06 ± 2.79)pmol/L] was not statistically significant (t =1.40,P ＞0.05].The thyroid volume of iodine sufficient group[(20.9 ± 6.1 )cm3] was higher than that iodine appropriate group [(17.9 ± 5.6)cm3,t =2.11,P ＜ 0.05].ConclusionsSufficient quantities of iodine intake may affect the thyroid of elderly people.Whether the quantity of iodine intake of the elderly population should be decreased or not need to be further studied.
