Patient noncompliance with the physician's prescribed therapeutic regimen is a serious problem in glaucoma because of the possibility of blindness. In this report the compliance with medical treatment of 67 patients with chronic glaucoma was studied for 2 years and 45% of the patient was identified as noncomplier. The authors' observations relative to noncompliance were lack of the knowledge of disease and its prognosis, little concern about disease, side effects of medication, improper timing and increased number of medication dosage, long-term use of medication, improperties of the physician-patient interaction, and other serious medical disorder, etc. The noncompliance does not correlate with the patient's age, sex, education, marital status, previous surgery for glaucoma,concerh of family, and increased waiting time to see the doctor.

OBJECTIVETo investigate the effect of siRNA silencing the role of C-Jun N-terminal Kinase (JNK) gene in excessive endoplasmic reticulum stress on lung ischemia/reperfusion injury.

METHODSMouse model of pulmonary ischemia reperfusion injury (PIRI) in situ was established with unilateral lung in vivo. Seventy experimental mice were randomly allocated into seven groups (n = 10): Sham group (Sham group), ischemia reperfusion group (I/R), PBS+ Lipofectamine2000TM transfection reagent group (I/R + PBS+ Lipo group), negative control group (I/R+ SCR group), JNK-siRNA group (I/R + siRNA(JNK1), siRNA(JNK2), siRNA(JNK3)). Mice were euthanized after experimental time out, and left lung tissue was extracted. Wet/dry lung weight ratio (W/D) and total lung water content (TLW) were tested. Light microscope, alveolar damage quantitative evaluation index (IQA) and electron microscope were observed. The expression levels of JNK and glucose regulatex protein(GRP78) were detected by RT-PCR and Western blot. Apoptosis of lung tissue was determined by TUNEL.

RESULTSCompared with Sham group, all indicators above of I/R + PBS + Lipo group and I/R + SCR group were significantly increased (P < 0.01), and compared with I/R group, those indicators of the three groups all had no notable difference; those indicators were not statistically different between I/R + PBS + Lipo group and I/R + SCR group, and compared to the three groups, the above indicators in JNK-siRNA group were lower (P < 0.05, P < 0.01) except that the expression levels of GRP78 was not statistically different.

CONCLUSIONI/R induces excessive ERS in lung tissue, in which JNK pathway participates in apoptosis, leading to lung tissue injury.

OBJECTIVETo study the possible role of hTERT and c-myc in endometrial carcinogenesis.

METHODSThe expression of hTERT and c-myc mRNA was examined by in situ hybridization of endometrial samples from 14 cases with simple hyperplasia, 10 with complex hyperplasia, 8 with atypical hyperplasia and 42 with endometrioid carcinoma.

RESULTSExpression of hTERT was demonstrated in samples with simple hyperplasia, complex hyperplasia, atypical hyperplasia and carcinoma at frequencies of 2/14, 4/8, 8/10 and 39/42 (92.9%), respectively. The prevalence and intensity of the hTERT signal was greater in the carcinomas and lesions with atypical hyperplasia than those with simple or complex hyperplasia (P < 0.05). The expression of c-myc was demonstrated in samples with simple hyperplasia, complex hyperplasia, atypical hyperplasia and carcinoma at frequencies of 3/14, 1/8, 5/10 and 23/42 (54.8%), respectively. The frequency of c-myc expression was higher in carcinomas and hyperplastic lesions with atypia than those in lesions with simple or complex hyperplasia without atypia (P < 0.05). The expression of hTERT was shown to be correlated with the level of differentiation (P < 0.05), while the c-myc expression appeared to be associated with the depth of myometrial invasion (P < 0.05). The expression levels of hTERT and c-myc were not found to be correlated with each other in the tissues examined (P > 0.05).

CONCLUSIONSThe expression of hTERT and c-myc may be involved in the progression from the endometrial aypical hyperplasia to invasive carcinoma. The correlation between hTERT and c-myc in endometrial hyperplasia and carcinoma are not found.

OBJECTIVEThe aim of this study was to investigate the role of macrophages in promotion of ovarian tumor cell proliferation mediated by over-expression of antimicrobial peptide LL-37.

METHODSTo co-culture ovarian tumor cells SKOV3, 3AO and HO-8910 with macrophages. The Transwell(®) inserts system was used in the co-culture model. The effect of macrophages promoted ovarian tumor cell proliferation was assessed by BrdU-ELISA and cell number counting. Expressions of mRNA and protein of LL-37 in the macrophages and SKOV3 cells were determined by RT-PCR and Western blot analysis. To observe that LL-37 is responsible for macrophage-promoted ovarian tumor cells growth, LL-37 neutralizing antibody was added to abrogate the LL-37 activation.

RESULTSThe cell number assay showed that after 4 days coincubation with macrophages in the proportion of 1:0.5, the number of SKOV3 cells increased from (6.0 ± 0.5)×10(4) to (11.8 ± 1.3)×10(4), showing a significant difference (P < 0.05). It also showed that the growth of the SKOV3 cells was dependent on the macrophage number (P < 0.05). The number variability of 3AO and HO-8910 cells was as the same as SKOV3 cells upon co-culture with macrophages. As determined by BrdU-ELISA, the resulted proliferation of ovarian tumor cells was similar to the result of cell number counting. RT-PCR and Western blot results showed that the expression of LL-37 mRNA and protein in the macrophages was remarkably enhanced in a time dependent manner upon coincubation with SKOV3 cells, but did not work in SKOV3 cells. BrdU-ELISA assay exhibited that treatment of cells with LL-37 significantly stimulated HO-8910 and 3AO cell proliferation. Addition of LL-37 neutralizing antibody markedly inhibited macrophage-promoted ovarian tumor cell (SKOV3, 3AO and HO-8910 cells) proliferation. The OD values of these three cells were decreased from 2.95 ± 0.11 to 1.45 ± 0.04, from 3.39 ± 0.36 to 1.32 ± 0.09 and from 3.93 ± 0.17 to 1.68 ± 0.23, respectively (P < 0.05).

CONCLUSIONSOver-expression and release of LL-37 from macrophages is responsible for proliferation of ovarian tumor cells in co-culture condition. The data presented indicate that LL-37 may be critical for macrophage-induced tumor progression.

Objective To investigate the effect ofplatelet-derived growth factor (PDGF) and conditional medium of U87 glioma cells on the migration ability of human mesenchymal stem cells (hMSCs) to understand the possible role of PDGF in the directional migration of hMSCs toward gliomas. Methods hMSCs were isolated from the whole bone marrow by adherent culture, and the expression of PDGF receptor (PDGFR-α, β) in the cells was examined by RT-PCR. In vitro migration assay was performed using transwell inserts to observe the effect of PDGF (0, 5, 50, and 125 ng/mL) and the conditional medium on the directional migration ability ofhMSCs. The changes in the migration ability of hMSCs in response to addition of anti-PDGF antibody in the conditional medium were investigated. Results RT-PCR detected the expression of PDGFR- αand PDGFR-β mRNA in the isolated hMSCs. In the cell migration assay, both PDGF and the conditional medium induced directional migration of hMSCs (P<0.05), which was significantly suppressed by anti-PDGF antibody P<0.05). Conclusion With chemokine-like activities, PDGF concentration-dependently enhances the directional migration of hMSCs toward gliomas in vitro.

OBJECTIVETo observe the clinical effect of Yangyin Yiqi Huoxue Recipe (YYHR, the basic recipe of Yangyin Tongnao Granule) in treatment of ischemic stroke patients of deficiency of qi and yin syndrome (DQYS) and static blood obstructing collaterals syndrome (SBOCS).

METHODSTotally 312 patients were assigned to the control group (86 cases) and the treatment group (226 cases) using strati- fied randomized allocation method. Patients in the treatment group were treated with modified YYHR, while those in the control group took Xueshuan Xinmaining. The treatment course was 4 weeks for all. Constituent ratios of the acute stage and the recovery stage of DQYS and SBOCS and their complicated syndromes were observed in the two groups. Changes of the clinical curative effect, clinical symptoms integral, whole blood viscosity ratio, plasma viscosity ratio, hematocrit, erythrocyte sedimentation rate (ESR), total cho- lesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C), and low density lipoprotein cholesterol (LDL-C) were detected in the two groups before and after treatment.

RESULTSThere was statistical difference in constituent ratios of the acute stage and the recovery stage of DQYS SBOCS and its complicated syndromes between the two groups (P < 0.01). DQYS and SBOCS was basic syndrome types of the two groups. The cured and markedly effective rate was 71.24%(161/226) in the treatment group and 43.02% (37/86) in the control group. The total effective rate was 91.15% (206/226) in the treatment group, higher than that of the control group (76.74%, 66/86) with statistical difference (P < 0.01). There was statistical difference in the clinical symptoms integral, whole blood viscosity ratio, plasma viscosity ratio, hematocrit, ESR, TC, TG,HDL-C, and LDL-C (P < 0.05, P < 0.01).

CONCLUSIONSSymptoms of ischemic stroke patients could be improved by modified YYHR. Indices such as the whole blood viscosity, plasma viscosity ratio, hematocrit, ESR, abnormal metabolism of blood lipids were also significantly improved. Pathological changes of blood stasis induced by qi-yin deficiency exist in ischemic stroke patients, and DQYS and SBOCS were basic syndrome types.
