Abstract
Objective:To discuss multiple-factor analysis of serum allergen distribution of patients with allergic rhinitis and level of main allergen IgE in Shenyang area, and to provide a scientific basis for the prevention of allergic rhinitis in this area.Method:Serum IgE was detected in 749 cases[501 cases of male (66.8%), and 248 cases of female (33.2%)], with allergic rhinitis.The age range was from 3 to 65 years old, and they were divided into 5 groups based on age. A questionnaire survey was conducted to analyze the distribution of serum allergens and to carry out a multiple-factor analysis of level of the main allergen IgE in patients.Result:The primary allergen was house dust mite/dust mite in each age group, and the differences in the positive rate of elm, mold, cat/dog fur scurf, cockroach and ragweed among different groups were statistically significant(P<0.01 or P<0.05).The ingested allergen sequencing for all age groups: the distribution of 7-14 years old group and 15-35 years old group were consistent with that of the whole, among the under 6 years old group, mango and pineapple was ranked 1st,beef and mutton was ranked 2nd,the occurrence rate of shrimp and crab rose to the 3rd place, among the 36-60 years old group, mango, pineapple and milk was ranked 1st, egg was ranked 2nd, and beef and mutton ranked 3rd, the differences in positive rate of mango and pineapple, beef and mutton, crab and nut among all groups were statistically significant(P<0.01 or P<0.05).The IgE level of cockroach was impacted by the allergic history, home cultivation of flowers and plants and animal domestication. The IgE level of mold was impacted by sex, allergy history, home rearing of pet and furniture updates. The IgE level of wormwood was impacted by allergy history and asthma history. The IgE level of peanut was impacted by age and allergy history. The IgE level of egg was impacted by history of food and drink allergy, home cultivation of flowers and plants and home rearing of pet. The IgE level of crab was impacted by the allergy history and home rearing of pet.Conclusion: The primary inhaled allergen in all groups is house dust mite/dust mite, and the ingested allergen varies in each group, which has provided a reference basis for prevention of ingested allergy.The varying influence factors for IgE level of primary allergens could be used to prevent the patients from contacting the allergen,and each risk factor has become a focus of prevention and control for patients, offering a major help to the prevention and treatment of allergic rhinitis.

Abstract
Objective: To understand the prevalence and distribution of hypertension in population aged 15 years and over in Guizhou province and provide evidence for the prevention and management of hypertension. Methods: Face to face interviews using national standard questionnaire were conducted among the study subjects selected in Guizhou through multi-stage random sampling. Blood pressure measurement for them was done with Omron HEM-1300 professional portable blood pressure monitor. SPSS 19.0 software was used for statistical analysis. The ratio was compared by the χ(2) test. The influencing factors of hypertension was analyzed by multivariate logistic regression analysis. Results: A total of 13 480 participants were investigated, including 5 509 (40.8%) men and 7 971 (59.2%) women; 6 558 (48.6%) urban residents and 6 922 (51.4%) rural residents. Among the subjects surveyed, 3 232 (23.9%) were smokers, 2 412 (17.9%) were alcoholic and 4 859 (36.0%) were obese or overweight. A total of 3 937 (29.2%) hypertension patients were found. The prevalence of hypertension was 29.2%. The standardized prevalence of hypertension were 18.97% (compared with national population composition) and 21.16% (compared with Guizhou province population composition), respectively. The hypertension prevalence in men and women were 29.8% and 28.8%, respectively. The hypertension prevalence in rural population (35.8%) was higher than that in urban population (22.2%). The difference was statistically significant (P<0.001). The hypertension prevalence in people aged 65 years and over was 56.2%. The prevalence of hypertension were 34.3% and 27.6% in smokers and non-smokers, 39.2% and 27.0% in alcoholic and non-alcoholic and 40.7% and 22.7% in obese or overweight group and normal or less weight group, respectively. There were significant statistical differences in prevalence of hypertension among the population in urban area and rural area, with different age, education levels, smoking status, drinking status and BMI (P<0.001). Conclusions: The prevalence of hypertension in Guizhou was at a high level. The hypertension prevalence in rural area was higher than that in urban area. Hypertension prevalence increased significantly with age. The prevalence of hypertension was negatively associated with the education level of the people. Older age, living in rural area, smoking, drinking, obesity were the risk factors for hypertension.

Abstract
The organic content of municipal solid waste has long been an attractive source of renewable energy, mainly as a solid fuel in waste-to-energy plants. This study focuses on the potential to use microbial fuel cells to convert municipal solid waste organics into energy using various operational conditions. The results showed that two-chamber microbial fuel cells with carbon felt and carbon felt allocation had a higher maximal power density (20.12 and 30.47 mW m(-2) for 1.5 and 4 L, respectively) than those of other electrode plate allocations. Most two-chamber microbial fuel cells (1.5 and 4 L) had a higher maximal power density than single-chamber ones with corresponding electrode plate allocations. Municipal solid waste with alkali hydrolysis pre-treatment and K3Fe(CN)6 as an electron acceptor improved the maximal power density to 1817.88 mW m(-2) (~0.49% coulomb efficiency, from 0.05-0.49%). The maximal power density from experiments using individual 1.5 and 4 L two-chamber microbial fuel cells, and serial and parallel connections of 1.5 and 4 L two-chamber microbial fuel cells, was found to be in the order of individual 4 L (30.47 mW m(-2)) > serial connection of 1.5 and 4 L (27.75) > individual 1.5 L (20.12) > parallel connection of 1.5 and 4 L (17.04) two-chamber microbial fuel cells . The power density using municipal solid waste microbial fuel cells was compared with information in the literature and discussed.

Abstract
Rapid growth of rigid waste polyurethane (WPUR) foam from refrigerators attracts the attention all over the world. In this study, glycolysis was chosen to treat WPUR from scrapped refrigerators collected in Shanghai, China. Glycolysis reagents and catalysts were selected. The results indicated that the glycolysis efficiency of ethylene glycol (EG) was higher than that of diethylene glycol, and the catalytic efficiency of alkali metal salts (NaOH) was more excellent than that of triethanolamine and organic salts of alkali metal (NaAc). When EG was 100%WPUR as a glycolysis reagent and NaOH was 1%WPUR as a catalyst at a constant temperature of 197.85°C for 2 h, the glycolysis product had the highest glycolysis conversion rate. In order to maximize the recycling of WPUR, regenerative Polyurethane was performed by adding 10% distilled mixed polyol, which conformed to the QB/T 26689-2011 requirements.

Abstract
The novel human oncogene hWAPL is associated with uterine cervical cancer. The HPV16 E5 oncoprotein could induce genomic instability in normal human cells. However, the mechanism of E5 interaction with hWAPL still awaits definition. In our present studies, the eukaryotic expression plasmids, pcDNA3-hWAPL and pcDNA3-hWAPL-E5 were constructed and carried out to vaccinate mice directly. The result that indicated the polyclonal antibody titer in immunized mice sera was increased by enzyme-linked immunosorbent assay. In addition, the proliferative responses of immunized mice spleen cells showed the optical densities values in vaccinated group remarkably higher than that in the control group. In conclusion, the recombinant plasmids could induce strong humoral and cellular immune response and exhibited great potential as therapeutic targets in the treatment of cervical cancer. However, the result didn't show significant difference in group with coexpression of HPV16 E5-hWAPL and group with only hWAPL expression. Consistent with these observations, we demonstrated that HPV16 E5 was not the optimal factor to cooperate with hWAPL in gene therapy.

Abstract
BACKGROUND To investigate the optimal codons of dihydrofolate reductase (dhfr) minus Chinese hamster ovary cells (CHO dhfr-). METHODS A cDNA library of CHO dhfr- containing high abundence mRNA was constructed and protein-coding sequences were obtained after identification and analysis. Codon frequence of CHO dhf- was compared with that of Chinese hamster in CUTG database. Then codon usage variation among cDNA was investigated using correspondence analysis (COA). RESULTS Fifty qualified cDNAs from CHO dhfr- were selected, which encodes proteins of high abundence. Comparing with the codon frequence of Chinese hamster, the highest frequence of synonymous codons for amino acids in CHO dhfr- cells were the same as Chinese hamster except that of Arg and Pro. This method of COA identifies the first main factor which can account for the largest fractions (14.7%) of variation among cDNAs. Twenty-two synonymous codons were identified as the optimal codons of CHO cell. CONCLUSION CHO dhfr- cell has its own optimal codons, it is suggested that codon bias is one of reasons for functional diversity of different mammal cells and it is an effective stratagy to modification of the codon usage of the foreign gene according to the optimal codons of CHO dhfr- to increase the production of foreign gene.

Abstract
More than 21% of the Chinese herbs tested contained substances in their aqueous extracts inhibitory to conidial germination of the powdery mildew fungus Oidium murrayae. Extracts from Chinese rhubarb and Japanese knotweed were very effective in controlling powdery mildew on cucumber, pumpkin, and eggplant. The inhibitory substance in Chinese rhubarb was soluble in polar solvents and less soluble in nonpolar solvents. The inhibitor in the aqueous extract was not dialyzable in the membrane tubing with molecular weight cut-off of 14,000, but was exchangeable by anion but not cation exchange resins, indicating that the inhibitor has a molecular weight larger than 14,000 and negative charge on its molecule.

Abstract
1. Cardiac fibroblasts play an important regulatory role in cardiac remodelling by undergoing proliferation, differentiation and upregulating various gene products, including some cytokines and extracellular matrix (ECM) proteins. A highly potent mediator of cardiac remodelling is angiotensin (Ang) II. 2. In the present study, the suppression subtractive hybridization method was used to identify differentially expressed cDNAs in adult rat cardiac fibroblasts induced by AngII. 3. Following mRNA isolation of non-stimulated and AngII-stimulated cells, cDNAs of both populations were prepared and subtracted by suppression polymerase chain reaction. Sequencing of the partially enriched cDNAs identified 36 genes differentially expressed, including ECM proteins (pro-alpha(1) collagen type III, fibronectin), structural protein (spectrin), enzyme (GTP-specific succinyl-CoA synthetase), transcriptional regulators (glucocorticoid-induced leucine zipper, inhibitor of DNA binding 3) and proteins involved in cell division control (cdc2) or cell signalling (insulin-like growth factor binding protein-3, mutant p53-binding protein, grp75, CGI-121, protein phosphatase type 2A, tspan-2 and Sam68). 4. The diversity of genes identified in the present study further emphasises the central role of AngII in the regulation of cardiac remodelling.

Abstract
The dust from the vaporized tissue released during a mastectomy presents a hazard to the patients and the operating room personnel. More dust has been noted using the conventional electrocautery pencil in dissecting breast tissue than with the metal knife used in the past. It is very important to reduce the hazardous dust released during mastectomy. For this study 80 patients undergoing mastectomy for breast cancer from March to June 2001 were divided into two groups: 1) those whose dissections were performed with a combination of an electrocautery pencil and suction with an intravenous infusion catheter (40 cases) and 2) those whose dissections were performed with the conventional method in which the electrocautery pencil was handled by the surgeon and the metal suction tube was used separately by an assistant (40 cases). During mastectomy the personal air sampler was affixed to the operator's neck to collect the dust from the vaporized tissue. The concentrations of the total dust were significantly lower in the combined electrocautery-suction method (mean 5.56 ± 3.26 μg/m3) than in the conventional method (mean 34.81 ± 4.83 μg/m3) during mastectomy ( P < 0.05). Although the operating time and blood loss were less in the combined method than in the conventional method this difference was not statistically significant ( P > 0.05). The combined method of using the electrocautery pencil for dissecting breast tissue along with the intravenous infusion catheter reduced the concentrations of the total dust from the vaporized tissue plume. Furthermore this method reduces the hazards of dust to the surgeons and operating room personnel. Additionally the cost of this combined method is lower than that of the conventional method.

Abstract
Using reverse transcriptase-polymerase chain reaction (RT-PCR) the changes of the angiotensin II receptor subtype 1-a (AT1a) and 1-b (AT1b) mRNA levels were examined in hypertrophied ventricles caused by ventral aorta-caval fistula of SD rats. The results show as follows. (1) Three days after operation, the ventricular weight increased significantly, whereas the level of AT1a and AT1b mRNA in both ventricles remained unchanged. (2) Twelve days after operation, the weight increase of both ventricles was more evident, the levels of AT1a and AT1b mRNA in the right ventricle increased (by 62.6% and 72.0%), as compared with control. In the left ventricle, on the other hand, the level of AT1a mRNA increased by 79.0%, while the level of AT1b mRNA showed no obvious increase. (3) Thirty-five days after operation, the levels of AT1a and AT1b mRNA in both ventricles increased still more significant, (i.e., 70.0% and 83.9% in the right and 96.5% and 86.9% in the left). Moreover, 12 d and 35 d after operation, the level of AT1a mRNA was higher than that of AT1b mRNA in both ventricles. (4) There was a positive correlation between the degree of ventricular hypertrophy with the level of AT1 mRNA in ventricular myocardium (r = 0.6168-0.8223). The results suggest that the increased mRNA expression of AT1 in myocardial hypertrophy caused by volume overload may be a mechanism underlying the increased responsiveness of hypertrophic myocardial cells to Ang II, and a difference in the expression between AT1a and AT1b mRNAs in myocardial hypertrophy may be related to the different physiological or pathophysiological roles of Ang II, mediated by the two subtypes of AT1.

Abstract
The acronym HELLP describes a syndrome of (H) hemolysis, (EL) elevated liver enzymes, and (LP) low platelets, which symptomatically defines a unique group of preeclamptic/eclamptic women. Pregnancies complicated by this syndrome are associated with poor maternal and fetal outcome. This poses a considerable challenge to the anesthesiologists as many of these patients require emergent Cesarean section. We reported a 30-year-old woman with gestation of 32 wk who sustained Cesarean section under the impression of pregnancy with HELLP syndrome. General anesthesia was performed for this patient. The preoperative evaluation, general management, and intraoperative monitoring system were described. The individual role and use of labetalol and propofol were also discussed in this report.

Abstract
From Nov. 1976 to Dec. 1989, 9 patients with congenital coronary artery-cardial chamber fistula were operated upon in our hospital. In this series right coronary artery-right ventricle fistula was found in 3 patients, right coronary artery-left ventricle fistula in 2, left coronary artery-right ventricle fistula in 2, left circumflex artery-right atrium fistula in 1, and bilateral coronary artery-cardiac chamber fistula in 1. Cardiopulmonary bypass was performed in 8. The fistula was closed by interrupted mattress sutures outside the cardiac chamber plus ligation of terminal portion of the coronary artery near the fistula in 5 patients, and by mattress sutures inside the dilated coronary artery or cardiac chamber in other 4. There was no operative death in the 8 patients with single fistula. One patient with bilateral coronary artery fistula died from hypoxemia postoperatively. Late complications or recurrent fistulas were not found in the follow-up period from 3 months to 12 years. The diagnosis, operative indications and technique of closing fistula were discussed.

Abstract
Southern blot hybridization was performed with probe v-erbB + A in 4 subjects. Two of them were patients with similar erythroid alterations of bone marrow: one of them was diagnosed as erythroleukemia (EL). The other two were members of a same family (husband and wife). The husband had normal erythroid cellularity of bone marrow but the wife and their 7 living sons and daughters had erythroid hypercellularity. In the second generation of this family 4 hematological patients (1 with AML and 3 with CAA) were found in the past decade. Rearrangement of cerbB and c-erbA genes was found in 3 of the 4 subjects (2 with EL and the wife mentioned above). They had 4 new hybridization bands besides 3 germlines, but the husband had only 3 germlines. The result suggests that using Southern blot hybridization technique with probe v-erbB + A, the rearrangement of c-erbB/c-erbA genes might be a diagnostic indicator of erythroleukemia at early stage of leukomogenesis in familial and sporadic patients. The etiological significance of the rearrangement of c-erbB/c-erbA in leukomogenesis was discussed.

Abstract
Thin section immuno-electron microscopy has been successfully applied to investigate and identify the classical and mild form of HFRS viruses isolated in the People's Republic of China. The results showed that all the 8 strains studied (derived from different parts of China, adapted in different cell lines) share a common morphology and morphogenesis. Essentially, the viruses possess characteristics of members of the Bunyaviridae Family, however, differing by a larger size and size variation and formation of cytoplasmic viral inclusions.

Abstract
Purified rat renal brush-border membrane vesicles possess a heat-labile enzyme activity which hydrolyses NAD+. A reciprocal relationship exists between the disappearance of NAD+ and the appearance of adenosine; 2 mol of Pi are liberated from each mol of NAD+ incubated with brush-border membrane vesicles. Freezing and thawing brush-border membrane vesicles does not enhance the initial rate of NAD+ hydrolysis. Preincubation of brush-border membrane vesicles with NAD+ results in inhibition of Na+-dependent Pi-transport activity, whereas Na+-dependent glucose transport is not affected. EDTA, which prevents the release of Pi from NAD+ and which itself has no direct effect on brush-border membrane Pi transport, reverses the NAD+ inhibition of Na+-dependent Pi transport. These results suggest that it is the Pi liberated from NAD+ and not NAD+ itself that inhibits Na+-dependent Pi transport.
