Objective To investigate the expression of E-cadherin and matrix metallopeptidase 7(MMP-7)and their significance in basal-like and Her-2 over-expressing breast carcinoma. Methods The protein expression of E-cadherin and MMP-7 were analyzed by immunohistochemical method in 20 cases of basal-like breast carcinoma and 21 cases of Her-2 over-expressing breast carcinoma.Statistical method was used to analyze the clinicopathological performance.Patients were followed up from 6 to 60 months.Results The ratio of basal-like breast carcinoma and invasive ductal carcinoma was 3.4%(20/501).the mean age was 49 years.The mean size of basal-like breast carcinoma(2.1 cm)was smaller than that of Her2 over-expressing breast carcinoma(3.0 cm)(P<0.05).The 5-year survival rate of patients with basal-like breast carcinoma was obviously(40.0%) lower than that of Her-2 over-expressing breast carcinoma (71.4%)(P<0.05),though,the 3-year survival rate was similar between the two groups.The protein expression of E-cadherin was down-regulated and even deficient in basal-like breast carcinoma(P<0.05).The protein expression of MMP-7 was higher in basal-1ike breast carcinoma than that in Her-2 overexpressing breast carcinoma(P<0.05).Conclusion Down-regulated expression of E-cadherin and upregulated expression of MMP-7 may be one of the mechanisms leading to high metastasis of basal-like breast carcinoma.

Objective:
To evaluate the dietary quality of residents in Wenzhou City, Zhejiang Province, so as to provide the basis for future health education and nutrition intervention programs.
Methods:
A stratified multi-stage random sampling method was used to select residents aged 18 years and older in 6 counties (cities, districts) of Wenzhou City as the study subjects, “24-hour dietary review for 3 consecutive days” was adopted to collect dietary intake, and the diet balance index (DBI_16) scoring method was applied to evaluate the dietary quality.
Results:
This study analyzed the dietary quality of 406 residents in Wenzhou City, including 197 males (48.52%) and 209 females (51.48%). The majority of the residents were aged 18-44 years (254 residents, 62.56%). The median DBI total score was -31 (interquartile range, 8), and 404 residents had insufficient dietary intake, accounting for 99.51%. The median DBI positive score was 5 (interquartile range, 6), and 288 residents had appropriate dietary intake, accounting for 70.94%. The median DBI negative score was 37 (interquartile range, 6), and 210 residents had a high level of insufficient dietary intake, accounting for 51.72%. Five dietary patterns, namely A, B, C, E and F, were identified, with pattern B being the most dominant, accounting for 75.62% of the total (307 individuals). Patterns D, H, I and G were not observed.
Conclusions
The dietary quality of the residents surveyed indicates the existence of dietary imbalances, mainly manifesting as inadequate intake. It is recommended to strengthen nutritional and health guidance.

OBJECTIVETo observe the effect of Yiqi Huoxue Qingre Huashi Recipe (YHQHR, a recipe capable of supplementing qi, activating blood, clearing heat, and dissipating dampness) on ulcer healing and Helicobacter pylori (Hp) eradication rate in Hp positive peptic ulcer patients, and to explore coccoid Hp occurrence in the eradication.
METHODSTotally 80 Hp positive peptic ulcer patients were assigned to the treatment group and the control groups by random digit table, 40 in each group. All patients received standard triple therapy of Western medicine for 2 successive weeks. Those in the control group additionally took omeprazole enteric coated tablet, 20 mg each time, once per day for 4 successive weeks. Those in the treatment group additionally took YHQHR, twice per day for 6 successive weeks. The ulcer healing was observed and recorded by gastroscope after discontinued medication of 14 days. The effective rate of ulcer healing under endoscope was statistically calculated. Rapid urease test (RUT) was performed in one small piece of tissue from corpora ventriculi and sinuses ventriculi using 14C breathe test (UBT). Gastric juice was collected from the stomach. Hp urease gene amplification test (urea A-PCR) was performed in living tissue from gastric antrum. Results obtained from the above three test methods were recorded and assessed to decide the final eradiation rate. Gastric mucosa tissue was observed under electron microscope,attempting to find non-eradicated Hp, which was further observed.
RESULTSThe total curative effect under gastroscope was 97.5% (39/40 cases) in the treatment group, obviously higher than that in the control group (80.0%, 32/40 cases) (P < 0.05). The eradication rate of Hp was 75.0% (30/40 cases), obviously better than that of the control group (52.5%, 21/40 cases) (P < 0.05). The total positive Hp numbers after treatment was 14C UBT (12), RUT (8), and urea A-PCR (27), respectively. The Hp positive rate detected by 14C UBT and RUT was lower than the Hp positive rate detected by urea A-PCR (P < 0.05). Rod-like and coccoid Hp bacteria could be observed under electron microscope.
CONCLUSIONYHQHR combined standard triple therapy was more effective than standard triple therapy alone in promoting ulcer healing and elevating the eradication rate of Hp.

Background Our previous study demonstrated that curcumin can induce the apoptosis of retinal pigment epithelial (RPE) cells and herein inhibit the proliferation of RPE cells,and it is proved that the intravitreous injection of 0.1mg curcumin has less adverse effect to ocular tissue, inferring a good applicative prospect in clinic. Objective The goal of this experiment was to evaluate the effectiveness of curcumin on the prevention and treatment of experimental proliferative vitreoretinopathy (PVR). Methods PVR models were induced by injection of 0.1ml RPE cells (containing 2×106 cells) into vitreous cavity in 40 eyes of 20 healthy and mature New Zealand albino rabbits.0. 1ml curcumin(0. 1 mg) was then injected into lateral eye of each model rabbit immediately following the injection of RPE cells,and the equal volume of normal saline solution containing 0. 5‰ DMSO was injected into the fellow eye of each model rabbit as controls. On 1,3,7,14,21 and 28 days after injection, the changes of cornea, aqueous humor, lens, vitreous and fundus were examined and recorded by slit lamp biomicroscope, indirect ophthalmoscope,fundus color camera and B-type ultrasonograph to evaluate the inflammatory response. The incidence rate of retinal detachment was calculated and compared between curcumin group and control group. Results The inflammatory reaction in anterior chamber and misty opacity in vitreous were found from 1 day through 3 days after injection, but no obvious proliferative strap and retinal detachment in all of the experimental eyes. On the 7th day after injection, inflammatory reaction was extinct in the anterior chamber of rabbit eyes, and proliferative strap occurred in 14 eyes(75% ) in the control group but only 2 eyes (10% ) in curcumin group,showing significant difference between these two groups (P<0. 01). No retinal detachment was seen in both the two groups. On 14,21 and 28 days after injection, the incidence rate of retinal detachment was 55% ,80% ,95% respectively in control group and that of curcumin group was 10% ,15% ,15% respectively,presenting considerably differences between two groups (P<0. 01, P<0. 01 ,P<0. 01 ). Conclusion Injection of curcumin into vitreous cavity can effectively inhibit the occurrence and development of PVR in rabbit.
