Objective To examine the expression of typeⅠcollagen in pulmonary arteries of rats with monocrotaline(MCT)-induced pulmonary hypertension(PH) and explore the mechanism of pulmonary vascular structural remodeling.Methods Twelve male Wistar rats were randomly divided into 2 groups: the MCT group(n=6) and the control group(n=6),which received a single intraperitoneal injection of MCT solution(60 mg?kg-1,the first day) or 9 g?L-1saline,respectively.After 3 weeks,mean of pulmonary artery pressure(mPAP),the value of right ventricle/(left ventricle plus septum)[RV/(LV+S)] and body weight were measured.Lung sections(HE stained) were observed under lightmicroscope for changes of the pulmonary arteries.The protein expression of typeⅠcollagen in pulmonary arteries was detected by immunohistochemical technique.Results Three weeks after MCT injection,compared with control group,mPAP and RV/(LV+S) increased significantly in MCT group[mPAP:(10.60?2.06) mmHg(1 mmHg=0.133 kPa) vs(32.40?3.24) mmHg,P

Objective To investigate the effects of early nasal intermittent positive pressure ventilation (NIPPV) compared with early continuous positive airway pressure (NCPAP) in low birth weight preterm infants with respiratory distress syndrome (RDS).Methods We performed a prospective,randomized controlled trial involving 364 low birth weight preterm infants with respiratory distress syndrome within 6 hours of birth.The infants were randomly assigned to NIPPV (n=188) or NCPAP (n=176) groups.Non invasive ventilation was initiated in the neonatal intensive care unit (NICU).The rate of mechanical intubation (within 3 days or 7 days),the use of pulmonary surfactant (PS),the rate of complications and mortality were compared between the two groups.Mann Whitney U,t and Chi-square tests were used for statistical analysis.Results The average time of invasive mechanical ventilation in NIPPV group were lower than that in NCPAP group[2.0 (1.0-4.0) d vs 7.0 (3.0-8.5) d,U=-3.457,P=0.001].The need for intubation and mechanical ventilation by day 3 and day 7 in the NIPPV group were less than those in the NCPAP group [day 3:4.8％ (9/188) vs 10.8％ (19/176),x2=4.621,P=0.032; day 7:9.0％ (17/188) vs 16.5％ (29/176),x2=4.551,P=0.033].In the NIPPV group,infants who got PS therapy was less than that in the NCPAP group [3.2％ (6/188) vs 8.5％ (15/176),x2=4.752,P=0.029].There was no significant difference in the fatality rate between the NIPPV and the NCPAP group [12.8％ (24/188) vs 10.8％ (19/176),P ＞ 0.05].There were no significant difference in the incidence of air leak,intracranial hemorrhage,periventricular leukomalacia,retinopathy of prematurity,necrotizing enterocolitis,patent ductus arteriosus,and bronchopulmonary dysplasia between the NIPPV group and the NCPAP group.Conclusion Among low birth weight prcterm infants with RDS,the early use of NIPPV reduces the need for PS,intubation and invasive ventilation compared with NCPAP.

OBJECTIVETo investigate the root canal curvature of permanent anterior teeth from Chuang population.

METHODS245 anterior teeth from Chuang population were collected and examined by X-ray radiography both from labiolingual and mesiodistal directions. For 218 type I anterior teeth, degree of root canal curvature, radius of curvature and length of the curved part of root canal were measured by a special electronic vernier caliper according to Schneider's and Schäfer's method and the data obtained were analyzed.

RESULTSRoot canals of anterior teeth from Chuang population were mainly of type I. The number of type II, III, IV were about 13 in mandibular central and 12 in mandibular lateral incisors. The incidence of curvature in maxillary central incisors, lateral incisors, canines and mandibular central incisors, lateral incisors, canines were 40%, 80%, 77%, 65%, 66%, 73% in mesiodistal directions, 62%, 69%, 70%, 62%, 41%, 61% in labiolingual directions respectively. The most curvature was moderate and happened in apical third. The heaviest curvature occurred in maxillary canines in mesiodistal direction and mandibular canines in labiolingual direction. The shortest radius and length of curvature occurred in maxillary lateral incisors.

CONCLUSIONRoot canal curvature of anterior tooth in Guangxi Chuang population is complex. The incidence of type II, III, IV is high in mandibular incisors.

Objective Color doppler ultrasonography of chronic Keshan disease (CKD) was evaluated to provide evidences for clinic diagnosis of the disease. Methods From September to Novermber 2009, according to "Diagnostic criteria of Keshan disease" (GB 17021-1997), 64 cases of CKD were randomly sampled from five Keshan diseased districts in Shandong province, Zoucheng, Sishui, Yishui, Wulian, Jvxian, and Pingyi as patient group. Thirty four healthy volunteers being checked up by Shandong Institute for Endemic Diseases Control and Research were put in control group. All the subjects were examined with Color doppler ultrasonography. The indexes of cardiac structure, left ventricular (LV) systolic function and LV diastolic function were measured.Results Left atrial internal diameter, LV end-diastolic internal diameter, LV end-systolic internal diameter, right ventricular diameter, aorta diameter, right atrial transverse diameter, right atrial long diameter and left ventricle mass of the patient group[(35.38 ± 6.89), (61.57 ± 8.61), (45.39 ± 10.29), (17.22 ± 3.79), (28.69 ± 2.81),(38.00 ± 6.05), (42.68 ± 8.65)mm, (283.22 ± 103.12)g] were higher than that of control group[(26.70 ± 3.27),(45.41 ± 4.93), (26.91 ± 4.35), (13.76 ± 2.27), (24.09 ± 2.89), (31.50 ± 3.32), (35.82 ± 3.14) mm, (156.03 ±39.86)g, t = 6.93, 10.09, 9.98, 4.87, 7.64, 5.81, 4.46, 6.90, all P＜ 0.05]. The LV ejection fraction and fractional shortening of the left ventricular of the patient group[(49.25 ± 14.33)%, (26.11 ± 9.17)%] were lower than that of control group[(73.88 ± 4.04)%, (42.88 ± 3.62)%, t = - 9.79, - 10.22, all P＜ 0.05]. Diffuse hypokinetic motion of the left ventricle reduced in 95% (61/64) of CKD patients, and 5% (3/64) of CKD patients had segmental LV dyskinesia. Seventy five per sent(48/64) of the patients accompanied with mitral regurgitation, and 39% (26/64) of these cases accompanied with tricuspid regurgitation. Meaningful Mitral or tricuspid regurgitation was not found out in control group. Conclusions The CKD patients' bore of atrio-ventricular cavity and LV mass are enlarged, and their motion of ventricle is reduced or partly reduced. They have poor heart function. Mitral regurgitation are more than tricuspid regurgitation. Color doppler Ultrasonography is important in diagnosis of chronic Keshan discase.

OBJECTIVETo study the passive immunization with human monoclonal antibodies as for prophylaxis of human cytomegalovirus (HCMV) infection.

METHODSFab monoclonal antibodies to HCMV were recovered by repertoire cloning of mRNA from a HCMV infected individual. Antigen binding specificity, CDR sequence of V(H) and V(L) and neutralizing activity on HCMV AD169 stain were analyzed in vitro. The light and heavy chain Fd fragment genes of Fab antibodies were further cloned into a recombinant baculovirus expression vector pAC-kappa-Fc to express intact IgG. Secreted products were purified with affinity chromatography using protein G.

RESULTSSDS-PAGE and Western blot confirmed the expression of the intact IgG. Immuno-blotting and -precipitation were used to identify HCMV proteins. One Fab monoclonal antibody recognized a conformational HCMV protein.

CONCLUSIONIgG antibodies can neutralize the HCMV AD169 strain efficiently at a titer of 2.5 microg/mL and may prove valuable for passive immunoprophylaxis against HCMV infection in humans.

Purpose: The purpose of this study was to assess the amount of variance in the coping strategies of patients with brain tumors that could be accounted for by resilience. Methods: This cross-sectional survey involved 95 patients who had experienced surgical, chemotherapy, or radiotherapy therapies for their brain tumors at least 1 month before data collection. The investigator collected data using the scales of the Ways of Coping Checklist-Revised and Resilience Scale. Data were analyzed using descriptive statistics, t tests, analysis of variance, Pearson product–moment correlation, and hierarchical multiple regression. Results: The results revealed that resilience was significantly positively associated with patients' problem-focused coping (r = .65, p < .001) and total coping (r = .49, p < .001). In addition, resilience accounted for 27% (R2inc = .27, p < .001) and 16% ((R2inc = .16, p < .001) of the distinct variances in predicting patients’ problem-focused coping and total coping. Conclusion The current results provide evidence to support the importance of resilience in shaping the coping strategies of relevant patients. As resilience shows a crucial element in patient coping with brain tumors, health team members should develop and employ appropriate strategies to improve the resilience of patients with brain tumors.

Objective To investigate the effect of 15d-PGJ2 on the expression of collagen type,CTGF and a-SMA in the hypertrophic scar in the rabbit ear,and the possibility of hypertrophic scar treated by 15d-PGJ2.Methods 18 New Zealand white rabbits were used to establish a hypertrophic scar model on the rabbit ear.The wounds were established as follows:2 cm × 3 cm wounds with total skin loses on the ventral side,2 wounds for each ear,totally 72 wounds.The wounds were randomly divided into the 15d-PGJ2 treatment group and NS control group.20μl 15d-PGJ2 or NS was injected into the ear scar once a day for 7 days.At 7,14 and 21 days after the injection,12 scars of each group were harvested.The expression of collagen type Ⅰ,CTGF and a-SMA was detected by immunohistochemical method.Results Excessive dermal scars on rabbit ears that were similar to human hypertrophic scar appeared in the two groups.Compared with the NS-treated scars group,the 15d-PGJ2-treated scars appeared to be smaller,softer,flatter and lighter in color.The expression of collagen type Ⅰ,CTGF and a-SMA in the 15d-PGJ2 group was significantly decreased as compared with that in the control group at different time points(P＜0.05).Conclusion 15d-PGJ2,the ligand of PPAR-r,can reduce the expression of collagen type Ⅰ,CTGF and a-SMA of hypertrophic scar in the rabbit ears and plays an important role in the prevention and treatment of hypertrophic scar.It may provide a new approach for the treatment of hypertrophic scar in clinical setting.

AIMTo explore the effect of remodeling and biomechanical properties after chronic treating with tetrahydrobiopterin (BH4) in spontaneously hypertensive rats.

METHODSThe spontaneously hypertensive rat(SHR) were given with BH4 chronically. The opening angle in the zero-stress state , wall-to-lumen area ratios (W/L) of thoracic aorta and the relationship between pressure and diameter (P-D) of mesenteric artery were measured by computer image analysis in 4, 16, and 26 week-old respectively.

RESULTSTreating with BH4 chronically from 4 weeks-old in SHR, there was a significant decrease in morphometric parameters of the thoracic aorta and an increase in the zero-stress state of opening angle of elastic artery. The P-D curve of mesenteric artery moved upward.

CONCLUSIONTreating with BH4 prevented the structure and function of artery from abnormal changing, including to attenuate the resistant vascular hypertrophy and recover the vascular elasticity and expansibility.
