Objective To explore the relationship between the expression of caveolin-1 and pathological grade, clinical stage in bladder carcinoma. Methods Caveolin-1 expression was detected in 63 cases of bladder carcinoma and 10 cases of normal bladder epithelial tissue using SABC immunohistochemistry. The clinical and pathological data of the patients were collected and used to make statistical analysis. Results The normal bladder mucosal epithelia had not caveolin-1 expression, while the positive rate of caveolin-1 expression was 34.92% in bladder carcinoma. The positive rates of caveolin-1 expression in the grades I, II and III of bladder carcinoma were 0%, 2.86%, 54.28%, respectively, which had a significant difference(P

Objective To study one simple, safe and effective method of periorbital rhytidectomy. Methods With turgescent anesthesia, 1 cm -extent was dissected laterally deep under musculus orbicularis oculi at the approach of eyebrow area. The musculus orbicularis oculi was fixed to the deep temporal fascia and frontal periosteum. The superciliary corrugator muscle and depressor muscle were exposured and cut. Then the eyelid blepharoalasty was performed through the skin incision, meanwhile the lateral pars orbitalis muscle was liberated to form an orbitalis muscle flap under the orbitalis muscle and the fat pad, which was fixed to the os orbitale periost by lifting tight to lateral and upper side. For patients with generous pars buccalis and obvious nose lip ditch, the cheekbone fat cushion was also hanged and fixed. Results 65 middle age female patients were followed up for 3～16 months. The scar was no obvious, glabellar wrinkle and canthal wrinkle disappeared at static state, relaxed upper eyelid and eyebrow prolapse reached to complete correct, nasolabial groove wrinkle obvious lessened. 95 % patients were satisfacted with the appearance. Conjunctival edema was found in 4 cases, and disappeared within 1 months. There were no facial nerve injury and other complications. Conclusions It is a new incisional approach that avoids the facial nerves and lessens fossa orbitalis retrogradation. The operative procedure is simple and safe, and its incision is occult. The wound is small and restores rapidly, but the effect is reliable and lasting. It proves to be an ideal approach for face rejuvenation.

Objective To investigate the effect of neonatal hypoxic myocardial injury and bradycardia on cerebral hemodynamics and brain tissue regional oxygen saturation (rSO2),and to provide patho-physiological evidence for treatment of neonatal hypoxic-ischemic encephalopathy (HIE) in acute phase.Methods Ninety nine full-term newborns admitted into Department of Neonatology,Peking University First Hospital from December,2005 to December,2008 were enrolled in this study.There were 18 newborns with both myocardial injury and HIE (group 1),31 newborns with HIE but without myocardial injury (group 2) and 50 cases of neonatal jaundice (control group).From 3 to 7 days after birth,Doppler ultrasound was used to measure systolic velocity (Vs),diastolic velocity (Vd) and resistance index (RI) of the anterior cerebral artery; and brain tissue rSO2 was detected by near infrared spectroscopy.The differences among groups were compared by variance analysis and LSD test.Brain tissue rSO2 before and after treatment of 20 newborns with bradycardia for various causes were detected and the difference was compared by paired t test.Results (1) Vs of group 1,group 2 and the control group was (19.35±5.13),(29.35±4.28) and (32.62±7.47) cm/s respectively; Vd was (6.43±2.98),(11.21±3.16) and (11.50±3.03) cm/s; RI was 0.68±0.10,0.62±0.03 and 0.64±0.06; brain tissue rSO2 was (52.4± 2.8)％,(54.6±3.1)％ and (62.1±1.9)％.There were significant differences among the three group(F=29.999,19.393,5.283 and 137.952,P＜0.01).Vs,Vd and rSO2 of group 1 were lower than that of group 2 and the control group (P＜0.05).RI of group 1 was higher than that of group 2 and the control group (P＜0.05).Vs and rSO2 of group 2 were lower than that of control group,but there were no differences between the two groups in Vd and RI.(2) The brain tissue rSO2 of newborns with bradycardia after treatment was higher than that before treatment [(58.7±4.6)％ vs (50.9±3.2)％,t=6.239,P＜0.01].Conclusions The disturbance of cerebral hemodynamics and cerebral oxygenation in HIE newborns are aggravated by hypoxic myocardial injury.Stable heart rate might be very important to early treatment for HIE.

Objective To study the serum immunoglobulin IgG,IgM,IgA and complements C3,C4 level changes in hand foot and mouth disease (HFMD) combined with acute flaccid paralysis (AFP).Methods The cases were divided into three groups in this study,including 30 cases of HFMD,30 cases of HFMD combined with AFP,and 30 cases of healthy(normal control group).Immunoturbidimetric assay was used to test the level changes of IgG,IgM,IgA,and complements C3,C4.Results The IgG,IgA,C3 and C4 in HFMD combined with AFP group were (5.49±1.04) g/L,(0.39±0.27) g/L,(0.65.±0.19) g/L and (0.16.±0.11) g/L respectively,lower than those in HFMD group((7.07± 1.63) g/L,(0.55±0.32) g/L,(0.97.±0.18) g/L,(0.23.±0.09) g/L) and normal control group((9.58±1.42) g/L,(0.81±0.33) g/L,(1.28.±0.25) g/L,(0.34.±0.16) g/L),there were statistically significant differences among groups(F=12.04,1.84,1.65,1.29;P=0.031,0.020,0.018,0.025).However,the expression of IgM in HFMD combined with AFP group was (1.34±0.26) g/L,higher than that in HFMD group((1.02±0.29) g/L) and normal control group ((0.76±0.28) g/L),the difference was statistically significant(F=3.62,P=0.014).Conclusion HFMD combined with AFP exists severe humoral immune dysfunction,which provides a theoretical evidence for the prevention and treatment of HFMD combined with AFP.

Objective To explore the relationship between health-promoting lifestyle and work engagement in nurses of traditional Chinese medicine hospitals. Methods Totally 527 nurses from 3A level hospitals of the first, second, third affiliated to Zhejiang University of Traditional Chinese Medicine were investigated by the Chinese revision of Health-Promoting Lifestyle Scale, Chinese version of Utrecht Work Engagement Scale. Results M ultiple regression analysis showed that nurse health-promoting lifestyle had a significant correlation with work engagement, F = 8.987, P < 0.01. Among them, the self-realization dimension to the nurse work engagement most affected, t = 3.287, P < 0.01. Conclusions Improving nurses′health-promoting lifestyle can raise the level of work engagement and stabilize nursing staff and improve quality of care in traditional Chinese medicine hospitals.

Objective:To identify the vision care access in rural primary health institutions and the utilization of vision inspections among rural residents. Methods:Survey data was collected from primary health institutions ( town-ship health centers and village clinics) and households. The descriptive statistics and multivariate regression analysis were applied to analyze data. Results:The household survey data shows that 33. 2% of rural residents self-reported having poor vision, and 22. 1% of rural residents stated that they had ever used vision care (vision screening or vison examinations) . The health facilities survey data shows that 84% of township health centers and 44% of village clinics can provide vision care. The multivariate analysis shows that the vision care access in township health centers is sig-nificantly correlated with the probability of residents’ utilization of vision care, but there is no significant correlation between the provision of vision care in village clinics and its utilization. Conclusions:The vision care access is low in rural China though there is a huge demand therefore. Inadequate supply of primary vision care services in primary health institutions may result in low utilization among rural residents. It is suggested that the government further pro-mote the National Public Health Service Program and strengthen the capacity of primary health facilities to provide primary vision care. To do so, an increase in the utilization of vision care among rural residents can be expected, which would thereby reduce potential losses caused by further vision impairment.

Objective To investigate the clinical value of high frequency ultrasound in discovering secondary pathological changes in infant with developmental dysplasia of the hip (DDH).Methods Thirtyfour infants with 36 dislocation hips were involved.Among them,32 were with unilateral dislocation of hip joint,2 were with bilateral dislocation of hip joint.High frequency ultrasound were used to observe the morphological changes of hip glenoid labrum,adipose hyperplasia in acetabulum,thickness variation of articular capsule,and development of the ossification center of the femoral head.Besides,the morphological changes of hip glenoid labrum and adipose hyperplasia in acetabul were compared with those from MRI.Results The sensitivity and specificity of ultrasound in diagnosing glenoid labral introversion were 82 ％ and 100％ respectively.The coincidence rate of diagnosing glenoid labral introversion and glenoid labral extroversion were both 83％.Adipose hyperplasias in acetabul were clearly seen in 31 hips using ultrasound.The thickness of articular capsule in the affected hip and in the healthy hip was (2.8 ± 0.6)mm versus (1.7 ± 0.4) mm,and the difference was obviously significant (P ＜0.01).The ossification center of the femoral head in the 34 infants were classified as the following four types:① which was smaller in the affected side than in the healthy side (22/34);②which was shown in the healthy side (7/34) but not in the affected side;③ which in both sides were not shown (4/34);④ which in both sides were small (1/34).Conclusions Ultrasound is a method of simple,rapid,non-invasive in diagnosing DDH,and it can be used to discover secondary pathological changes in infant with DDH,which provide important reference for clinical diagnosis and treatment.

The primary cilium, a sensory organelle that protrudes from the surface of most eukaryotic cells, receives and transduces various critical signals that are essential for normal development and homeostasis. Structural or functional disruption of primary cilia causes a number of human diseases, including cancer. Primary cilia has cross talks with cell cycle and it may act as a cell cycle checkpoint to suppress cancer development. Moreover, primary cilia has cross-regulation with autophagy, which may affect tumor progression. We then discuss the association of the primary cilia with several oncogenic signaling pathways, including Shh, Wnt, Notch and platelet-derived growth factor receptor (PDGFR). Since these signaling pathways are often over-activated in many types of human cancers, primary cilia are likely to play a role in the tumorigenesis by modulating these pathways. Finally, we summarize current progress on the role of cilia during tumorigenesis and the challenges that the cilia-cancer field faces.
