Objective To observe the effects of epidermal growth factor (EGF) on cell proliferation and cell cycle of cultured bovine corneal endothelial cells. Methods Bovine corneal endothelial cells were cultured with different concentrations of hEGF (1, 10 and 100 ng/mL). MTT test was performed to evaluate the cell proliferation. The bovine corneal endothelial cells were divided into two groups:control group (cultured in DMEM) and EGF-stimulated group (cultured in DMEM with EGF). Flow cytometry was performed to determine the cell cycle phases on the third and seventh day. Results Compared with the control, EGF enhanced the cell proliferation in a dose-related response. 10 ng/mL and 100 ng/mL EGF were much more effective than 1 ng/mL.On the third day, S phase cells accounted for 24.5% and G_2-M phase cells 0.08% in the control group,while 24.6% and 0.06%, respectively in the EGF-stimulated group. However, on the seventh day, those came to 20.8% and 0.41% in the control group, and 18.2% and 1.55% in the EGF-stimulated group,indicating a significant change in the cell cycle (P

Objective To investigate the efficacy and safety of transthoracic minimally invasive occlusion operation guided by transesophageal echocardiography for the treatment of congenital atrial or/and ventricular septal defects (ASD/VSD).Methods The clinical data of a total of 44 patients who underwent surgical occlusion operation from September 2013 to June 2015 were summarized.The whole course of occlusion procedure were dynamically monitored and guided by transesophageal echocardiography.All the patients were followed up regularly by electrocardiogram and echocardiograph.Results Among the 44 patients,43 patients(28 VSDs and 16 ASDs,including one patient suffered with VSD and ASD simultaneously)were occluded successfully,and the other patient with VSD who failed in the surgery was converted to open heart repair.The occlusion operations were finished within 22 to 48 min.The length of incision spaned from 2 to 4.5 cm.The ventilator was used for 1 to 5 hours.The total drainge volumes were recorded each patient from 0 to 50 mL.The postoperative hospitalization stay was 2 to 6 days,and all patients survived and were discharged.During the follow-up of 1 to 12 months, there was no cases with A-V conduction block,valve incompetent,cardiac arrhythmia and residual shunt of heart septel defect.Conclusion Transthoraic mini-invasive surgical occlusion of atrial and ventricular septal defects is a therapeutic method with less trauma,higher safety and feasiblity,faster recovery,and the short-term therapeutic effect is satisfying.

Objective To study the risk factors of hyperthyroid heart diseases(HHD) by analyzing clinical features of patients in order to provide a scientific basis for prevention and treatment of HHD. Methods Nine hundred and eighty two cases were selected as objective from in-patient data of Thyroid Disease Treatment Centre of Shandong Province. The cases were divided into hyperthyroidism group and HHD group. The variables of etiology,sex, age, duration of disease, TSH, FT3, FT4 and TRAb were analyzed by comparative analysis. The risk factors were analyzed by logistic regression. Results The prevalence of hyperthyroidism complicated hyperthyroid heart disease was 7.7%(76/982), age, duration of diseases, FT3, TRAb in the HHD group were [(51.4 ± 11.5), (6.3 ±2.1) years, 21.6 pmol/L, 71.6 U/L], in hyperthyroidism group were [(37.9 ± 9.8), (2.6 ± 1.3) years, 14.9pmol/L, 49.6 U/L]. The differences were statistically significant(u = 9.93,15.23, T = 44954,48792.5, P ＜ 0.05)between the two groups. The factors of the older, higher FT3 and TRAb, longer duration, Graves disease (OR =1.751,1.470,1.483,1.445,1.234) increased the risk of HHD. Conclusions Graves disease, longer duration, old age, higher FT3 and TRAb are the risk factors of HHD. Timely prevention and control of risk factors is necessary to reduce the incidence of HHD.

OBJECTIVETo study whether apoptosis plays a role in controlling the number of olfactory receptor neurons, so as to reveal the specialty and mystery of neurogenesis.

METHODSUsing terminal deoxynucleotidyl transferase-mediated dUTP-fluorescein nick end labeling (TUNEL) and transmission electron microscopy to detect apoptosis in olfactory mucosa of normal adult rats and damaged olfactory mucosa of 16, 32, 48 hours and 3, 7, 30 days after bulbectomy.

RESULTSIn normal olfactory epithelium, a subpopulation of immature neurons, as well as mature neurons, showed internucleosomal DNA-fragmentation. The number of TUNEL-labeled neurons increased dramatically 32 hours after removal of olfactory bulb. Then it declined quickly and remained at low level. Ultrastructural data of olfactory mucosa showed that the feature of apoptotic neurons was chromatin condensation and cell shrinkage. Besides, some dying cells were characterized by the formation of numerous autophagic vacuoles, and few had some of the features of necrosis but without obvious mitochondrial swelling.

CONCLUSIONSApoptosis might play a role in turnover of the olfactory epithelium and regeneration in adult rats. There might be other two types of neural death through different mechanism.

OBJECTIVETo understand the process of Cistanche tubulosa.

METHODThe process of seed germination and parasitism was observed using stereomicroscope.

RESULTSeedling of C. tubulosa sprouted after forty day without host root's contact in fields, a tube-like-organ formed and grew auger-type from host root, the tuber apex where touches host root swelled and formed haustorium. Haustorium intruded host root epidermis and vascular bundles, and released brown substances. Then, embryo bud with six or more young leaves formed, finally the swelled tuber-like-organ broken and seed coat shed. Due to the parasitism of C. tubulosa, the host root near stem site swelled, but the other part, shrunk and disappered gradually.

CONCLUSIONSeed of C. tubulosa could germinate indepently in fields. Tuber-like-organ formatin, haustorium formation and bud formation are key steps of C. tubulosa seedling development.

OBJECTIVETo explore the relationship of clinical features, therapeutic measures, laboratory findings, the origin of tumor cells as well as prognosis in Chinese patients with diffuse large B-cell lymphoma (DLBCL).

METHODSOne hundred and six patients with DLBCL were retrospectively assayed and followed up, the international prognostic index (IPI) score, Ann Arbor staging, ECOG score, the origin of tumor cells and different therapeutic methods were analyzed.

RESULTSAccording to the IPI, there were 61 cases (57.5%) with low-intermediate risk and 45 (42.5%) with intermediate-high risk. According to Ann Arbor staging, there were 8 phase I cases (7.5%), 16 phase II (15.0%), 54 phase III (51.0%) and 28 phase IV (26.5%). Twenty-five cases (23.6%) were accompanied with bone marrow invasion, 16 of them were diagnosed as lymphosarcoma cell leukemia; 38 cases with ECOG score ≥ 2; 67 cases (63.2%) had an increased LDH level; 59 cases (55.7%) had B symptom. The response rate (RR) for the whole group was 71.7%, the complete remission (CR) rate was 59.4% (63 cases), the partial remission (PR) rate was 12.3% (13 cases), the stable disease rate was 2.8% (3 cases) and the death rate was 27.4% (29 cases). The 4-year survival rate was 72.6%. Univariate analysis indicated that eight factors were related with prognosis (P < 0.05), including IPI score, Ann Arbor staging, ECOG score, the origin of tumor cells, LDH level, bone marrow invasion, different therapeutic methods and whether or not CR. Multivariate analysis showed that the origin of non-germinal center (HR = 4.24, P = 0.001), bone marrow invasion (HR = 2.08, P = 0.012), whether or not CR (HR = 2.72, P = 0.006) and therapy modality (HR = 2.58, P = 0.009) were significant factors for prognosis.

CONCLUSIONThe bone marrow invasion and the origin of tumor cells are independent risk factors for prognosis. The rituximab combined with chemotherapy can significantly improve the therapeutic effect of the DLBCL, and hematopoietic stem cell transplantation is the best choice for treating patients with DLBCL.

OBJECTIVETo investigate the blood pressure control rate and related influencing factors in hypertensive outpatients.

METHODSIn this multicentre, cross-sectional registration survey, hypertensive outpatients were recruited from department of cardiology, nephrology and endocrinology of 92 tertiary hospitals in 22 cites across China. Each centre enrolled more than 50 hypertensive outpatients aged 18 years or older between 20 April 2009 and 31 May 2009. Outpatients were surveyed by clinical interview with BP measurement and questionnaire.

RESULTSA total of 5086 subjects were enrolled, 2032 in department of cardiology, 1510 in department of endocrinology and 1544 in department of nephrology, 27.1% and 25.3% patients were in Grade 2 or Grade 3 hypertension, 37.2% patients were complicated with diabetes, 22.4% with coronary artery disease, and 18.4% with renal-dysfunction. Overall, controlled BP was achieved in 30.6% patients. The control rate was 45.9% in uncomplicated hypertensive patients, 31.3% in hypertensive patients with coronary artery disease, 14.9% in patients with diabetes, and 13.2% in patients with renal-dysfunction. Calcium channel blocker (56.6%) and angiotensin-II receptor blockers (32.0%) were the most frequently used medications. The mean number of antihypertensive agents prescribed per patient was 1.73, over 54.1% patients were treated with more than 2 antihypertensive drugs. Combination therapy or single-pill combination with various anti-hypertensive components was prescribed to 8.3% and 12.7% hypertensive patients as initial therapy. Multiple logistic regression analysis showed that lower BMI, no alcohol intake, free medical care, no diabetes, no renal-dysfunction, lipid-lowering therapy, shorter interval of visiting physicians, regular taking antihypertensive medications, physical activity were the factors related to satisfactory blood pressure control rate in hypertensive outpatients.

CONCLUSIONSBlood pressure control rate among Chinese hypertensive outpatients was increased compared with epidemiological survey in 2002. BMI, co-morbidities, lower combination treatment rate, poor compliance were the key reasons for lower BP control rate. Increased use of combination therapy instead of monotherapy should be encouraged to hypertensive outpatients to improve BP control rate.
