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.

Objective To investigate the blood pressure control rate and related influencing factors in hypertensive outpatients. Methods In 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. Results A 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. Conclusions Blood 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.

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.

This is a case of a 35-year-old Gravida 5 Para 5 (5005) who underwent curettage for retained placental fragments after delivering her fifth child. Within 16-month postpartum, the patient had nonspecific occasional abdominal pain and oligomenorrhea. Imaging studies revealed a uterine defect with a bowel segment passing through. A referral to a tertiary-level hospital was made. Hysteroscopy was attempted; however, an obliterated cervical canal was encountered. Laparoscopy revealed a 10 cm ileal segment completely herniating into a 2.5 cm uterine defect at the posterior uterine wall. Laparoscopic enterolysis followed by hysterectomy, extracorporeal resection, and anastomosis of the involved ileal segment was performed. This is an uncommon case of an iatrogenic uterine perforation following curettage after a term pregnancy. Its unique clinical presentation and intraoperative findings resulted in an equally unique array of surgical approach.

OBJECTIVETo elucidate the clinical features of patients at early stage of severe acute respiratory syndrome (SARS).

METHODSFifty-three cases of early SARS were studied retrospectively. The data reviewed included those of epidemiology, clinical manifestations, laboratory investigation and roentgenology.

RESULTSThe patients consisted of 24 men and 29 women, aged 10.85 years (mean 38+/-16.7 years), including 9 infected health-care professionals (17.0%). The mean incubation period was 7.3+/-7.0 days (3.14 days). The onset symptoms were characterized by fever (100%), cough (49.1%), maylgia (24.5%), shortness of breath (20.8%), malaise (17.0%),and diarrhea (5.7%). Routine blood test during the first to the fifth day of the disease revealed WBCs less than 4.0x10(9) /L in 33 patients (62.3%), 4.0-10.0x10(9)/L in 18 patients (34.0%), lymphopenia in 36 patients (67.9%), and PLT less than 100.0x10(9) in 7 patients (13.2%). The main abnormal X-ray finding was single (75.4%) or bilateral (15.1%) localized patchy clouding opacity. The decrease of arterial partial pressure of oxygen occurred in 26 patients (49.1%). The damage of several organs was common, including the elevated ALT or AST in 20 patients (37.7%), elevated BUN or SCR in 6 patients (11.3%) and elevated LDH or CK or HBDH in 23 patients (43.4%).

CONCLUSIONThe clinical manifestations of SARS at the early stage were complex. The close monitoring of the blood cell counts, the blood gas analysis and chest radiography might be crucial to the early diagnosis.

OBJECTIVETo study the curative effects of pirfenidone (PF) on pulmonary fibrosis induced by paraquat (PQ) in mice and to provide the theoretical basis for clinical treatment.

METHODSNinety adult healthy male ICR mice were randomly divided into six groups: control group, PQ group, 2 mg/kg Dexamethasone group, 25 mg/kg PF group, 50 mg/kg PF group and 100 mg/kg PF group, there were 15 mice in each group. The corresponding volume of normal saline was given to the each mouse in control group according to the weight, after 2 h 0.1% CMC was given to the each mouse of control group one time by intragastric administration, then the CMC was administrated at regular time until sacrifice. All mice for other 5 groups were exposed to 100 mg/kg PQ by intragastric administration. At 2 h after exposure to PQ, 0.02 ml/10 g dexamethasone and 25, 50, 100 mg/kg PF were given to mice for dexamethasone group and for 3 PF groups by intragastric administration each day for 49 days, respectively. The lung coefficient was calculated and pathological changes of lung tissue were observed by HE staining for each mouse. The hydroxyproline (HYP) level in lung tissue was measured for each mouse. The mRNA level of and the protein level of TGF-β(1) in lung tissue for each mouse were determined, and the protein level of TGF-β(1) in the bronchus-alveolus lavage fluid (BALF) of each mouse was detected.

RESULTSThe survival rates on the 3rd day in PQ group, 3 PF groups and dexamethasone group were 53.33%, 46.67%, 73.33%, 86.67% and 80%, respectively. The survival rates on the 3rd day in dexamethasone group, 50 mg/kg and 100 mg/kg PF groups were significantly higher than those of PQ group and 25 mg/kg PF group (P < 0.05). The lung coefficients of 3 PF groups were significantly lower than that of the PQ group (P < 0.05). The lung tissue HYP levels of dexamethasone group and 3 PF groups were 50.95 ± 11.65, 44.52 ± 9.48, 43.27 ± 6.01 and 40.82 ± 5.90 mg/g respectively, which were significantly lower than that (74.27 ± 3.68) of PQ group (P < 0.01). The TGF-β(1) protein levels of BALF in dexamethasone group, 50 and 100 mg/kg PF groups were 22.03 ± 7.27, 27.75 ± 5.84 and 21.31 ± 6.82 ng/ml respectively, which were significantly lower than that (52.52 ± 15.51) ng/ml of PQ group (P < 0.01) The expression level of TGF-β(1) mRNA in 100 mg/kg PF group decreased significantly, as compared with PQ group (P < 0.01).

CONCLUSIONPF could reduce the collagen deposition and pulmonary fibrosis induced by PQ in mice lungs.
