Investigation on awareness of perimenopausal hormone replacement therapy among a part of the medical care personnel in Guiyang / 中华健康管理学杂志

Objective To study the awareness of perimenopausal hormone replacement therapy (HRT) among a part of the medical care personnel in Guiyang . Methods A survey was conducted among 500 medical staff members in 4 hospitals of Guiyang by cluster random sampling using questionnaire about HRT. Results The survey showed that 74.6% (373/500) medical staff thought that the hormone replacement therapy was necessary to perimenopausal women; 96.7% (87/90) of obstetrics and gynecology doctors believed that it was necessary for perimenopausal women to use HRT,which was significantly higher than the doctors of other specialties 68.6% (166/242) and the nurses group 71.4% (120/168) (χ2=28.509, 23.537, P<0.01). Only 5.8%(29/500) of the medical personnel were willing to recommend HRT. In light of the attitude for recommending HRT, the obstetricians and gynecologists group was more significantly higher than the other specialties doctors group (χ2=86.781, P<0.01). Conclusion The knowledge of hormone replacement therapy in part of Guiyang medical personnel is not sufficient;the recommending rate of HRT was low;the side effects of HRT was still a concern. There are differences between obstetrics and gynecology doctors and doctors other specialties and nurses in HRT knowledge.

Mechanism of heat shock protein 90 for regulating 26S proteasome in hyperthermia / 南方医科大学学报

<p><b>OBJECTIVE</b>To investigate the mechanism by which heat shock protein 90 (HSP90) regulates 26S proteasome in hyperthermia.</p><p><b>METHODS</b>Hyperthermic HepG2 cell models established by exposure of the cells to 42 degrees celsius; for 3, 6, 12, and 24 h were examined for production of reactive oxygen species (ROS) and cell proliferation, and the changes in Hsp90α and 26S proteasome were analyzed.</p><p><b>RESULTS</b>ROS production in the cells increased significantly after hyperthermia (F=28.958, P<0.001), and the cell proliferation was suppressed progressively as the heat exposure time extended (F=621.704, P<0.001). Hyperthermia up-regulated Hsp90α but decreased the expression level (F=164.174, P<0.001) and activity (F=133.043, P<0.001) of 26S proteasome. The cells transfected with a small interfering RNA targeting Hsp90α also showed significantly decreased expression of 26S proteasome (F=180.231, P<0.001).</p><p><b>CONCLUSION</b>The intracellular ROS production increases as the hyperthermia time extends. Heat stress and ROS together cause protein denature, leading to increased HSP90 consumption and further to HSP90 deficiency for maintaining 26S proteasome assembly and stability. The accumulation of denatured protein causes unfolded protein reaction in the cells to eventually result in cell death.</p>

Sheng-Mai-San attenuates contractile dysfunction and structural damage induced by chronic intermittent hypoxia in mice / 中国天然药物

Sheng-Mai-San (SMS), a well-known Chinese medicinal plant formula, is widely used for the treatment of cardiac diseases characterized by deficiency of Qi and Yin syndrome. A mouse chronic intermittent hypoxia (CIH) model was established to mimic the primary clinical features of deficiency of Qi and Yin syndrome. Mice experienced CIH for 28 days (nadir 7% to peak 8% oxygen, 20 min per day), resulting in left ventricle (LV) dysfunction and structure abnormalities. After administration of SMS (0.55, 1.1, and 5.5 g·kg(-1)·d(-1)) for four weeks, improved cardiac function was observed, as indicated by the increase in the ejection fraction from the LV on echocardiography. SMS also preserved the structural integrity of the LV against eccentric hypotrophy, tissue vacuolization, and mitochondrial injury as measured by histology, electron microscopy, and ultrasound assessments. Mechanistically, the antioxidant effects of SMS were demonstrated; SMS was able to suppress mitochondrial apoptosis as indicated by the reduction of several pro-apoptotic factors (Bax, cytochrome c, and cleaved caspase-3) and up-regulation of the anti-apoptosis factor Bcl-2. In conclusion, these results demonstrate that SMS treatment can protect the structure and function of the LV and that the protective effects of this formula are associated with the regulation of the mitochondrial apoptosis pathway.

Genotypes and serotypes of avian infectious bronchitis viruses isolated during 2009-2011 in Guangxi, China / 病毒学报

In order to investigate the prevalence and track genetic and antigenic evolutions of infectious bronchitis virus (IBV) and their prevalence in Guangxi, China since 1985, gene amplification and sequencing and virus neutralization (VN) test on chicken embryo tracheal organ cultures were used in genotyping and serotyping of 28 IBV isolates during 2009-2011 in Guangxi. The results of N gene sequencing and comparison showed that the 28 isolates and reference strains were classified into three groups, and most isolates belonged to group Ill, while the isolates in 1985-2008 belonged to groups IV and II. The data of VN test indicated that the 28 isolates belonged to 6 serotypes; among them, 71. 4% belonged to serotypes 1, 2, and 3, and 11 (39.3%) shared the same serotype with the current vaccine strains. Given the data of our previous study, it is found that prevalent serotypes and their proportions varied in different areas of Guangxi and during different periods. These data lay a good foundation for developing an oil-emulsified inactivated polyvalent vaccine containing local dominant serotypes for the effective prevention and control of infectious bronchitis.

Villous adenoma of the urinary tract: a clinicopathological study / 中华病理学杂志

<p><b>OBJECTIVE</b>To explore the clinicopathological features, immunophenotype, differential diagnosis, pathogenesis and prognosis of villous adenoma with poorly differentiated adenocarcinoma of the urinary tract.</p><p><b>METHODS</b>Clinical and pathologic findings of 3 cases of villous adenoma with poorly differentiated adenocarcinoma of the urinary tract were analyzed by gross examination, microscopic investigation and immunohistochemical staining. The related literatures were reviewed.</p><p><b>RESULTS</b>All of the three cases were middle-aged or elderly patients. Three cases all presented with hematuria and mucusuria. Endoscopic examination identified that case 1 had a polyp with broad attachment in the dome of bladder, case 2 had a solid mass in the ureter, and case 3 had a exophytic fungating tumor in the renal pelvis. Microscopically, case 1 revealed a papillary lesion with finger-like processes lined by pseudostratified columnar epithelium with abundant goblet cells. The cells demonstrated moderate degree dysplasia. In case 2 and case 3, both villous adenomas and poorly differentiated adenocarcinoma were observed, the adenoma cells arranged in a cribriform pattern, and the tumor cells showed severe atypia, mitotic activity, and transition with invasive poorly differentiated adenocarcinoma. Immunohistochemically, the tumor cells in three cases were positive for CK20, CEA,EMA and MUC-1; none of them expressed cdx-2 and PSA; In case 2 and 3, the same immunophenotype of villous adenomas and their associated adenocarcinomas was observed, but the number of the positive cells of p53 and Ki-67 staining were significantly increased in the area of adenocarcinomas than in that of the villous adenomas.</p><p><b>CONCLUSIONS</b>Villous adenoma of the urinary tract is rare. It can occur in the urinary bladder, urachus, renal pelvis, ureter and urethra. These lesions may have malignant potential and frequently coexist with other malignant tumors. So, villous adenoma of the urinary tract should be removed completely and sampled thoroughly to avoid missing a more aggressive component.</p>

Evaluation of antigenic relationship of Guangxi isolates of infectious bronchitis virus / 病毒学报

Monovalent antisera of 3 vaccine strains and 7 representative field isolates were prepared based on the comparison of genetic diversity of the hypervariable region I of S1 gene (HVR I from 3 infectious bronchitis (IB) vaccine strains (H120, Ma5 and 4/91) ,one reference strain M41 and 26 IB field isolates. These 30 strains were classified in 7 different genotypes, respectively. Virus-neutralizing test on tracheal organ cultures (TOC) with chicken embryo were used to evaluate relatedness values of the antigenicity based on the antibody titer, to analyze the antigenic relationships between the isolates and vaccine strains, as well as to determine the serotypes of 26 IB viruses isolated from the field in Guangxi between 1985 and 2008. The results showed 30 strains were classified into 7 distinct serotypes and there were two predominant serotypes within the 26 isolates, serotypes 1 (totally 13 isolates) and serotype 2 (totally 5 isolates), respectively. In addition, there were some differences observed between the results of serotyping and the genotyping (including the S1, N, M and 3'UTR). The results of the study demonstrated that there were different predominant serotypes and multiple serotypes of IBV circulated in Guangxi in recent years, antigenic variation existed between Guangxi field isolates and vaccine strains.
