A new method for the analysis of soluble solids content (SSC) in honey by near infrared spectroscopy (NIR) was developed, and moisture was also analyzed. The partial least square regression models of ...SSC and moisture were built for different pretreatments of the raw spectra in different spectral range. Good predictions were always obtained for all models. The best models of SSC and moisture were obtained by using Norris (3,2) smoothing + first derivative + multiplicative signal correction in total spectral range. The coefficient of determination (R(CV)2) and root mean square error of cross validation (RMSECV), the coefficient of determination (R(p)2) and root mean square error of validation sets (RMSEP) were 0.9986, 0.190, 0.9985 and 0.127 respectively for SSC, while for moisture they were 0.9984, 0.187, 0.9986 and 0.125 respectively. NIR could be used to analyze SSC and moisture in honey. The result of this article was better than that of related documents for moisture.
To study the effects of acute cold exposure on the inflammation and pathologic injuries in pulmonary of rats, and explore the mechanism induced by cold stress.
Forty male Wistar rats were randomly ...divided into five groups(n = 8): control group (23 ± 2) °C 2.5 h, -25°C 0.5 h group, -25°C 1 h group, -25°C 2 h group and -25°C 2.5 h group. Rats were exposed to cold at -25°C and no wind by keeping them in a low temperature chamber except control group. Rectal temperatures of the rats were measured before and after cold exposure. The morphological changes of pulmonary were observed by the optics microscope. The levels of tumer necrosis factor-α(TNF- α), interleukin-6 (IL-6) and interleukin-β (IL-1β) in lung tissue homogenate were measured by ELISA.
Compared to the control group, body core temperatures of the -25°C 1 h group, -25°C2 h group and -25°C 2.5 h group were decreased significantly, and the D-values of rectal temperature were increased before and after cold exposure (P < 0.05). The infiltration of inflammat
To study the distribution of pathogenic microorganisms in different genders, age groups and seasons in children with community-acquired pneumonia (CAP) and the relationship between the distribution ...of pathogenic microorganisms and clinical features.
A total of 1,155 children with CAP were enrolled, among whom there were 670 boys and 485 girls, with a mean age of 3.1±2.8 years (range: one month to 14 years). Indirect immunofluorescence assay, particle agglutination test, enzyme-linked immunosorbent assay, colloidal gold method. and bacterial culture were applied to determine common respiratory pathogenic microorganisms in sputum, throat swabs, blood samples, bronchoalveolar lavage fluid, and urine.
A total of 758 specimens (65.63%) were tested positive by pathogen detection. The top three dominant pathogens were Mycoplasma pneumoniae (MP, 43.64%), bacteria (15.12%), and respiratory syncytial virus (RSV, 9.26%), and the rate of mixed infection was 16.02%. The rates of MP infection between boys and girls with CA
Objective To explore the pathological changes of recurrent gliomas and the clinical value of operation. Methods A total of 13 patients with recurrent brain gliomas who underwent surgical treatment at ...the Department of Neurosurgery of Renji Hospital of Shanghai Jiao Tong University School of Medicine between January 2004 and January 2014 were retrospectively analyzed. The pathological changes of different grades of recurrent gliomas and the prognosis were compared. Results Among all patients, 7 of them (53.8%) pathologically upgraded, 5 of them (38.5%) remained the same, and one patient (7.7%) pathologically degraded. The median survival time of patients was 28 months (2-63 months), 1 year survival rate was 52%, and 2 year survival rate was 42%. Univariate analysis showed that the pathological level of recurrent gliomas, time between two operations>12 months, expressions of phosphatase and tensin homolog deleted on chromosome ten (PTEN) of patients with primary gliomas, and expressions of p53 and Ki-67 of pati
To observe the effect of transcutaneous acupoint electrical stimulation (TAES) of Zusanli (ST 36) on gastrointestinal activities in organophosphorus pesticide poisoning (OPP) patients undergoing ...emergency treatment so as to explore its action in scavenging gastrointestinal toxicant.
A total of 116 OPP patients were randomly divided into control group and TAES group (n=58 in each group) according to the simple random sampling method. All the patients received comprehensive treatment including gastric lavage, catharsis, oral administration of atropine Pralidoxime Chloride, Omeprazole, etc. For patients of the TAES group, TAES stimulation (30 Hz/60 Hz, 15-20 mA) was applied to bilateral Zusanli (ST 36) for 30 min, 3 times a day till black stool was discharged. The vomiting times after catharsis, the time of the first defecation and black stool discharge, the dosage of atropine and the length of patient stay in hospital were recorded.
Of the two 58 cases of OPP patients in the control and TAES groups, 11 (18.9%)
To investigate the early clinical effects and radiological outcome of dynamic cervical implant (DCI) internal fixation in treating cervical spondylosis, and evaluate its safety and efficiency.
From ...June 2009 to December 2011, 19 patients with cervical spondylosis correspond to the indication of DCI internal fixation in the study, including 5 cases of cervical spondylotic myelopathy and 14 cases of cervical spondylotic radiculopathy. There were 8 males and 11 females, aged from 35 to 54 years with a mean of 43.2 years. Pathological segments included C3,4 in 1 case, C4,5 in 6, C5,6 in 6, C6,7 in 4, C3,4 and C5,6, C6,7 in 2. All patients were treated with anterior discectomy and decompression and DCI internal fixation, meanwhile, 2 cases of them with anterior cervical corpectomy and fusion plate fixation. Clinical evaluation included Modified Japanese orthopedics association (mJOA), neck disability index (NDI), visual analogue scale (VAS) score and patient satisfaction index (PSI) at pre-operation and final foll
The paper analyzed principle of mechanical system of crawler travel system, and used multi-body dynamics software of RecurDyn to do simulation and analysis of walking state on flat road with soft ...soil of virtual prototype of compound obstacle crossing robot with master-slave track. The simulation results show that the gravity center of the prototype does not coincide with the geometric center, which leads down track of guide wheel to sink lower than other tracks, while the uneven pressure distribution may lead to locally grounding of track and reducing track life. So the rational allocation of gravity center of prototype should be paid attention to during design.
By analyzing the main physical and chemical properties and nutrient contents of camellia seeds,the variation of fat transformation and nutrients during the process of oil-tea camellia seed maturation ...were studied. The results showed that with maturation,the moisture content of camellia seed declined,the fresh seed yield changed little,the kernel rate increased slightly,and the dry seed rate and seed oil content rose; the acid value and POV of camellia seed oil were overall downward; the relative content of oleic acid in the ripening process was overall upward,while the contents of linoleic acid and linolenic acid decreased. Both the linoleic acid and linolenic acid were very significantly negatively correlated with the oleic acid content( p < or = 0. 01),the correlation coefficient were-0. 978 and-0. 957; the fat accumulation was negatively correlated with the total soluble sugar change( r =-0. 289),and positively correlated with soluble starch change( r = 0. 836) and soluble protein changes( r = 0. 703).

To investigate the association of traumatic severity with changes in lymphocyte subsets in the early stage after trauma.
Sixty-three male patients admitted within 4 hours after trauma were enrolled. ...According to injury severity score (ISS), the patients were divided into two groups: mild trauma group (ISS<16, n=35) and severe trauma group (ISS≥16, n=28). At admission, the patients peripheral blood were extracted to detect T lymphocytes subsets, blood routine test, blood biochemical and arterial blood gas analysis which were used to calculate the acute physiology and chronic health evaluation II (APACHEII) scores. The correlation of lymphocyte subsets and ISS score, and the correlation of lymphocyte subsets and APACHEII score were both analyzed statistically. Another 20 cases of healthy male adults were enrolled as the control group.
Compared with the healthy control group, CD3(+) T cell contents in blood were decreased obviously in mild trauma group and severe trauma group (0.648±0.112, 0.647±0.110 vs. 0.708±
