ApoE and LDL-R knocking out mouse may spontaneously develope atherosclerosis and so is applied in the research of atherosclerosis. These mouse model, the model generated by gene targeting, like IL-1, C-reactive protein, scavenger receptor, IgG Fc,C1q and CD44, play important role in research of inflammatory factor and immune factor on atherosclerosis.

OBJECTIVETo observe the clinical effects of essential hypertension treated with acupuncture at Siguan [Hegu (LI 4) and Taichong (LR 3)], Quchi (LI 11) and Xingjian (LR 2).

METHODSSixty cases of essential hypertension were randomly divided into an acupuncture group and a medication group, 30 cases in each group. Two groups of acupoint, which were (1) Siguan [Hegu (LI 4) and Taichong (LR 3)] and (2) Quchi (LI 11), Xingjian (LR 2), were selected alternatively in the acupuncture group, once everyday. In the medication group, captopril was prescribed for oral administration 25 mg per time, three times per day. Seven days made one session in both groups and totally three sessions were required.

RESULTS(1) After treatment, the blood pressure were decreased significantly in the two groups (all P < 0.01). Compared with the medication group, the diastolic pressure after 14 days, 21 days of treatment in the acupuncture group was decreased significantly (both P < 0.01). (2) In the terms of TCM syndrome score, the improvement of dizziness, soreness and weakness of waist and knees, palpitations was significant in the acupuncture group compared with that in the medication group(all P < 0.05). (3) The acupuncture group had less adverse reactions compared with the control group (P < 0.05).

CONCLUSIONAcupuncture at Hegu (LI4) and Taichong (LR 3), Quchi (LI 11) and Xingjian (LR 2) can effectively decrease blood pressure; the effect of controlling diastolic pressure is better than captopril. It can also improve the symptoms of dizziness, soreness and weakness of waist and knees, and palpitations.

Abstract?AlM:To investigate effect and safety of the limbal stem cell transplantation combined with low concentrations of mitomycin C for pterygium patients with type 2 diabetes mellitus (T2DM).? METHODS: Eighty patients of 96 pterygium eyes admitted to hospital were divided into groups of high concentration, low concentration group and the control group, and 3 groups were given pterygium excision combined with limbal stem cell transplantation. The high concentration group, the low concentration groups were given prior to stem cell transplantation 0. 2, 0. 1mg/mL mitomycin C coverage. The cure rate and recurrence rate in three groups of patients, as well as visual acuity before and after treatment were compared.?RESULTS: Three groups patients' visual acuity were significantly improved after treatment (P<0. 05), there was no significant difference before treatment in visual acuity (P>0. 05);epithelial healing time of high concentration group was significantly higher than low concentration group and the control group (P<0. 05), there was no significant difference between low concentration and control groups of epithelial healing time (P>0. 05); cure rates of low concentration group was higher than high dose group, the recurrence rate in low concentration group was lower than the high dose group.? CONCLUSlON: Pterygium excision combined with limbal stem cell transplantation has significant efficacy for pterygium, and mitomycin C can effectively reduce the relapse rate, but for the patients with T2DM concentration of mitomycin C should be reduced.

At present, a number of scientific research achievements has been formed. Scientific achievement is the crystallization of great efforts from scientific workers, and it's also the valuable treasure of human civilization. Standardization is an important way to promote the international communication of Chinese medicine, and it's significant in boosting China's scientific and technological progress, improving market competitiveness and promoting international trade. Transformation of scientific research to the guideline is not only beneficial to improving the technology content of the standard, but also to the conversion from scientific research achievements into productivity. Therefore, only by absorbing the advanced scientific and technological achievements, reproducing the theory of traditional Chinese medicine (TCM) and medical technology in standard form, can make TCM keep pace with the times. This study preliminarily explores for the method to transform scientific research achievements into guideline, in order to provide reference for the future technical specifications, thus to further the development of TCM.

Background There still is no a uniform diagnostic criteria for increasing population of dry eye.Studies showed that high tear osmotic pressure is one of causes of a variety of ocular surface discomfort,and the change of tear osmolality has been included in the definition of dry eye syndrome by Dry Eye World Study Group (DEWS) in 2007.It is very clinically significant to study the relationship of tear osmolality with dry eye.Objective This clinical trial was to study the correlation between tear osmolarity and dry eye severity based on Preferred Practice Pattern(PPP)of DEWS.Methods A descriptive study was performed.Fifty-four eyes of 54 patients with dry eye disease were asked to complete an evaluation of dry eye signs and symptoms questionnaire based on PPP.The ocular anterior segment was examined under the slit lamp biomicroscope.Cornealfluorescein staining,tear-film breakup time (BUT),Schirmer test Ⅰ (S Ⅰ t)without anesthesia were performed,and tear sample was collected for tear imageology and tear osmolarity admeasurement.The correlation between dry eye score with tear osmolarity was evaluated using Pearson linear correlation analysis.Written informed consent as obtained prior to any relevant medical procedure.Results The ratio of male and female patients was 1: 2 in this study.The negative correlations were found between tear osmolarity with S Ⅰ t or BUT(r =-0.456,-0.699,P＜0.01),and significantly positive correlations were found between tear osmolarity with tear imaging examination,corneal fluorescein staining,conjunctival hyperemia or dry eye symptom score(r=0.545,0.686,0.691,0.803,P＜0.01).Conclusions As a diagnostic method,tear osmolarity can objectively reflects dry eye severity.It can be a biomarker in dry eye severity grade when combined with clinical symptom.

Objective To investigate the effect and mechanism of metformin on endometrial carcinoma subline of progestin-resistance and find whether metformin could regulate progestin-resistance in endometrial carcinoma. Methods Ishikawa endometrial carcinoma cells were cultured for a long period in the presence of the synthetic medroxyprogesterone 17-acetate (MPA) to generate a subline refractory to the growth-suppressive effects of MPA,named Ishikawa/MPA cells. The effect of MPA (1, 5, 10, 20, 40 and 60 μmol/L) or metformin (1, 10, 20, 40, 60, 70 and 80 mmol/L) on proliferation of the Ishikawa/MPA and parental Ishikawa cells was detected by cell counting kit-8 (CCK-8) method. Western blot was used to detect the effect of metformin and(or)MPA on the expression of PR-B in the Ishikawa/MPA and Ishikawa cells. Results The Ishikawa/MPA showed that growth stimulation rather than inhibition in the Ishikawa cells after low MPA concentration treatment. The doubling time of Ishikawa/MPA cell lines were (43±4) hours and that of Ishikawa cell line were (47 ± 3) hours. No changes in doubling time were observed (t=0.349,P=0.572). Low concentration (1 and 5μmol/L) of MPA could promote the growth of Ishikawa/MPA cells (by 3% and 13%). High concentration (10, 20, 40 and 60 μmol/L) of MPA could inhibited the growth of Ishikawa/MPA cells (by 4%, 3%, 9%and 40%) and the growth of Ishikawa cells (by 41%, 55%, 65%and 66%). At the same concentration, the difference of inhibition rates between the two cell lines were statistically significant (P<0.01). Metformin (1, 10, 20, 40, 60, 70 and 80 mmol/L) could inhibite the growth of Ishikawa/MPA (by-10%, 20%, 56%, 89%, 97%, 98%and 99%) greater than those in parental Ishikawa cells (by-6%, 19%, 37%, 54%, 70%, 72%and 83%), and the inhibitory effect was dose-dependent manner. Western blot assay showed that for Ishikawa cells, the protein expression levels of PR-B in metformin group and MPA+metformin group were respectively (53.5±4.0)%and (37.7±5.2)%, which were higher than that in the control group [(23.4 ± 3.0)%], and there were significant the differences (P<0.01). For Ishikawa/MPA cells, the protein expression levels of PR-B in metformin group and MPA+metformin group were respectively (38.6 ± 1.7)%,(36.3 ± 2.5)%,which were higher than those in the control group [(6.4 ± 1.6)%], and there were also significant differences (P<0.01). Conclusion Metformin may regulate the progestin-resistance in endometrial carcinoma by increasing the expression of PR-B.
