Halomonas sp.BYS-1 was a moderately halophilic bacteria strain isolated from activated sludge,It could grow on MM with NaCl concentration from 0.1～2.6 mol/L and phenyl acetic acid as sole carbon souce. When BYS-1 grew in the media with different concentrations of NaCl, there was no obvious change in its intracellular Na+ contents , it accumulated K+, glutamic acid and betaine as osmoprotectants. Its intracellular contents of K+,glutamic acid and betaine increased by 1.9,2.4 and 13.6 times, respectively, when the concentration of NaCl increased from 0.1 mol/L to 2mol/L.

OBJECTIVETo explore the effect of Jiawei Yupingfeng Powder (JYP) on T-lymphocyte subsets in patients with senile chronic bronchitis in acute onset stage (SCB-AOS).

METHODSPatients were divided, according to the randomized controlled principle, into two groups, the 44 patients in the treated group and the 40 in the control group. The conventional western medicinal therapy was given to both groups, but to the treated group, JYP was administered additionally. The therapeutic course to them was 14 days. Changes of CD3, CD4, CD8 and the ratio of them were observed.

RESULTSIncrease of CD3, CD4 and CD4/CD8 (P < 0.05) and decrease of CD8 (P < 0.01) were significantly shown in the treated group after treatment, but no change in the control group. Besides, comparison of the total effective rate in the two groups also showed significant difference (P < 0.05).

CONCLUSIONCellular immune function disturbance exists in patients with SCB-AOS, JYP could enhance the efficacy by way of modulating cellular immune function.

OBJECTIVETo explore the clinical effects of locking plates in the treatment of intertrochanteric hip fractures.

METHODSFrom February 2006 to December 2008,108 patients with intertrochanteric hip fractures treated with locking plate and DHS were retrospective analyzed. Fifty-one patients were treated with locking plates, including 23 males and 28 females, aged 45 to 86 years old (averaged 66.0 years old); and fifty-seven patients were treated with DHS, including 26 males and 31 females,aged 43 to 81 years old (averaged 64.1 years old). The outcome measures collected for statistical analysis on the following aspects: operative time, blood loss, drainage, healing time, complications and Harris scores.

RESULTSOne hundred and eight patients were followed up ranging from 8 to 24 months (averaged 12.5 months). In locking plate group, the operative time was (87 +/- 14) minutes; blood loss was (367 +/- 213) ml; drainage was (63 +/- 14) ml; healing time was (11.9 +/- 3.4) weeks; 7 patients had complications; and the Harriss score was (85 +/- 6). While in DHS group, the operative time was (115 +/- 23) minutes; blood loss was (582 +/- 243) ml; drainage was (98 +/- 16) ml; healing time was (12.4 +/- 2.5) weeks; 9 patients had complications; and the Harriss score was (84 +/- 8). There were no significant differences in the healing time, complications and Harris scores between two groups (P > 0.05),but there were significant differences in the operative time,blood loss, drainage between two groups (P < 0.05). Comparing with DHS group, the locking plate group was of shorter operative time, fewer blood loss and drainage.

CONCLUSIONProximal femoral locking plate is simple, minimally invasive,stable fixation with fewer complications, and is an effective method for intertrochanteric hip fractures.

OBJECTIVEFor clarifying the situation of the natural infection of rodents having hemorrhagic fever with renal syndrome (HFRS) virus and to type Hantavirus (HV) using molecular technique in Shenzhen city in 2005, and offering guidance for prevention and control of HFRS.

METHODSData on the host animals was collected from the city of Shenzhen. ELISA and indirect immunofluorscent antibody(IFA) test were applied to the specific antibodies against HV in the sera of captured rats. Direct immunofluorscece assay was adopted to determine HFRS antigens and the lung tissues of the HV infected rats were inoculated into Meriones unguiculata to isolate HV. The whole viral RNA was extracted from the lung tissues of the HV infected rats and amplified the partial M fragments with RT-nested-PCR, using the HV genotype specific primers. The amplified genes were then sequenced, and subjected to genotyping and homology analysis.

RESULTS472 rodents were captured from Shenzhen in 2005. Surveillance on rats demonstrated 9.96% rats carrying HV (with a density of 8.25%) and the main host was Rattus norvegicus. In the blood samples of rats, anti-HV IgG antibodies were detectable in 56 cases by IFA, and proved to be positive in 76 cases by ELISA. We successfully isolated a HV strain designated as SZ2083 from Rattus norvegicus for the first time in Shenzhen and was identified to SEO type by RT-nested-PCR. Compared with the coding region of the M gene of HV L99 virus strain, the homologies of nucleotide among them were 97%, but the homology was 76% of the SZ2083 with HTN 76-118 virus strain.

CONCLUSIONResults showed the existence of natural epidemic areas of HFRS in Shenzhen city. Based on the results of sequencing, it is possible that the Seoul strain of HV might be the predominant serotype of virus harbored.

OBJECTIVETo analyze the correlation between pressure-derived collateral coronary flow (PDCF) and Rentrop grade of patients with acute myocardial infarction (AMI).

METHODSPDCF, determined by the ratio of P(w)/P(a), was measured in 29 patients with AMI of the first onset who received primary percutaneous coronary intervention (PCI) within 12 h after the onset. Sufficient collateral flow (group A, n=19) was defined as PDCF>0.24 and insufficient collateral flow (group B, n=10) as PDCF< or =0.24. Rentrop grade of the collateral flow was evaluated by coronary angiography. Echocardiography was performed on the 3rd and 30th day after PCI. The left ventricular ejection fraction, end-systolic and end-diastolic volumes, and the related indexes were obtained.

RESULTRentrop grade was significantly related to PDCF (r=0.75, P<0.01), but a wide range of PDCF was observed in patients with Rentrop grade< or =1.

CONCLUSIONPDCF measurement allows quantitative evaluation of the collateral flow in patients with AMI.

OBJECTIVEObstructive sleep apnea-hypopnea syndrome (OSAHS) may cause serious morbidities, such as systemic hypertension, diabetes, and cor pulmonale. However, currently no many reports on study of OSAHS in children are available. This study aimed to explore the effects of OSAHS on children's multiple systems.

METHODA total of 89 cases of children who came to the Sleep Treatment Center in the authors' hospital from March 2009 to December 2010 with snoring were tested with overnight polysomnography (PSG). They were classified into mild OSAHS group (n = 59, mean age of 5.71, SD = 2.46) and moderate to severe group (n = 30, mean age of 5.30, SD = 2.73) based on the PSG results, and 100 healthy children were selected as the control group (n = 100, mean age of 6 years, SD = 2.98). Data including height, weight, body mass index and blood pressure, peripheral blood routine, blood lipids, glucose and insulin, electrocardiogram and echocardiography were collected. Patients' adenoid face and abnormal occlusion were also recorded. Comparisons of the data were made among those groups.

RESULTMild OSAHS and moderate to severe group had significantly higher prevalence of adenoid face (23.7%, 26.7%), and abnormal occlusion (74.6%, 60.0%) than that in control group (0, 40%) (P < 0.05). There were no significant differences in terms of BMI between the OSAHS group and the control group, but the weight (kg) and height (cm) in the mild OSAHS group (23.3 ± 10.1, 114.9 ± 16.2) and moderate to severe group (21.9 ± 8.4, 110.8 ± 13.3) were lower than those of the control group (31.8 ± 10.1, 136.1 ± 15.1) (all P < 0.05). Compared with the control group, the level of HDL-C (mmol/L)and insulin (mU/L) in moderate and severe group decreased [(1.20 ± 0.30) vs. (1.40 ± 0.27), 2.79 (0.84 - 16.16) vs. 4.92 (0.76 - 16.80), P < 0.05], while the LDL-C (mmol/L) increased [(2.61 ± 0.75) vs. (2.32 ± 0.62), P < 0.05]. The red blood cell counts (× 10(12)/L) and the blood platelet counts (× 10(9)/L) in the mild OSAHS (4.93 ± 0.37, 292.92 ± 75.64) and moderate and severe OSAHS group (5.23 ± 0.22, 292.50 ± 63.05) were significantly higher in contrast to the control group (4.70 ± 0.31, 255.60 ± 69.12) (all P < 0.05), systolic blood pressure (mmHg) in mild group (98.54 ± 10.44) and moderate to severe group (99.13 ± 19.13) was significantly higher compared to control group (87.88 ± 11.37), and the heart rate (beats/min) in moderate to severe group (94.43 ± 10.64) was higher than those in control group (87.12 ± 16.20) (all P < 0.05). The mild OSAHS and moderate and severe OSAHS group had decreased right ventricular internal diameter [(14.24 ± 1.64) mm, (13.17 ± 2.07) mm ], increased main pulmonary artery diameter [(17.05 ± 3.33) mm, (16.33 ± 3.14) mm] and the thickness of right ventricular wall [(3.43 ± 0.26) mm, (3.57 ± 0.20) mm] compared to control group [ (16.10 ± 2.96) mm, (14.11 ± 2.52) mm, (3.32 ± 0.25) mm] (all P < 0.05).

CONCLUSIONOSAHS in children may be associated with craniofacial malformations, and may contribute to slow growth and development, elevated blood viscosity and blood pressure, metabolic abnormalities, and change cardiac structure.
