Objective To understand the blood ABO,Rh blood group distribution of the main nationalities in Baoshan city to set up the local rare blood group donors archives for meeting the voluntary blood donor recruitment and the need of clinical blood use. Methods The ABO,Rh were detected by the microplate method.124 RhD negative individuals were extracted and screened for C/c,E/e by the test tube method.Results Among 7 main ethnic groups with blood donor,the ABO blood group distribution of Han, Yi,Bai,Lisu and Hui nationalities were A>O>B>AB;which in Brown and Dai nationalities were O>B>A>AB;the Rh negative ratio was 0.33% in Han,0.35% in Yi,0.09% in Bai,0.00% in Brown,0.32% in Lisu,0.21% in Dai,0.18% Hui;the Rh pheno-types were mainly ccdee (60.5%),Ccdee (33.1 %),CCdee (4.0%)and ccdEe (2.4%).Conclusion The distribution rate of ABO blood group in Han,Yi,Bai,Lisu,Hui blood donors in Baoshan was consistent with the distribution of Han population in China;Brown and Dai are different from Han in China;the Rh negative frequency is 0.00%-0.35%,which reflects the regional and na-tional characteristics of blood group distribution in baoshan city.

Simultaneous determination of zinc, cadmium, tin, lead and copper was studied in 0.2-0.3M hydrochloric acid-methanol by 1.5 grade differential anodic stripping voltammetry. A stick silver base mercurial film electrode was used as a working electrode. The peak potential of Zn, Cd, Sn, Pb and Cu was distinctly separated each other being -1.05V, -0.74V -0.55V, -0.44V and -0.25V vs SCE, respectivly, in the above solvent electrolyte.Calibration curves of Cd, Sn, Pb and Cu in range of 20 to 600 ng/ml and Zn in range of 0.2 to 4 ug/ml showed linear relation. Canned foods could be analyzed, by dilution with the supporting electrolyte after digestion of the samples with mixed acid. The juice samples could be analyzed directly without digestion, by simple 5-2000 times dilution with the supporting electrolyte. Coefficient of variation and recovey was 6.7-8.0% and 91.2-107% respectively.

This paper is to report the study of the metabolism of lidamycin in vitro including in plasma and microsomes to guide clinical therapy. Lidamycin was quantified by detecting its active ingredient using HPLC-MS/MS. The metabolic stability of lidamycin in rat, Beagle dog, monkey and human plasma and liver microsomes, and its inhibition to cytochrome P450 isoforms in human liver microsomes were studied. Results showed that lidamycin was metabolized in the four species of plasma, and the sequence of metabolic rates in plasma were in rat > in dog > in human > in monkey. But among the four species of liver microsomes, lidamycin was metabolized only in monkey liver microsomes. There was almost no inhibition to cytochrome P450 isoforms at the concentrations of between 0.0005 and 10 ng x mL(-1). Therefore, the property of lidamycin metabolism in human is similar with that in dog, and metabolism of other drugs would not be decreased by cytochrome P450 as used along with lidamycin in clinic.

Objective: To examine the associations of sleep with overweight/obesity and central obesity in adults, so as to provide insights into improving sleep quality and preventing obesity in adults. Methods: Demographics, height, body weight, waist circumstance and sleep status were collected from the Hubei Provincial Surveillance Program for Adult Chronic Diseases and Their Risk Factors in 2020. Subjects' sleep condiction, overweight/obesity and central obesity were descriptively analyzed. The associations of sleep with overweight/obesity and central obesity were examined using a multivariable logistic regression model. Results: A total of 17 789 participants were recruited, with an average age of (56.21±13.05) years, 61.50% women, and mean duration of (7.18±1.56) h/d. There were 7 019 participants with snoring/asphyxia/suffocation (39.46%), 6 108 participants with sleep difficulty (34.34%), 8 064 participants with night waking at least twice (45.33%), 268 participants taking hypnotics (1.51%), and 6 267 participants with early morning awakening and difficulty in sleep again (35.23%), and there were 8 960 participants with overweight/obesity (50.37%) and 6 148 participants with central obesity (34.56%). Multivariable logistic regression analysis showed that sleep duration of <7 h/d (OR=1.081, 95%CI: 1.007-1.159), snoring/asphyxia/suffocation (OR=2.367, 95%CI: 2.222-2.521), and night waking at least twice (OR=1.106, 95%CI: 1.028-1.191) significantly correlated with overweight/obesity, and sleep duration of >8 h/d (OR=0.834, 95%CI: 0.761-0.913), snoring/asphyxia/suffocation (OR=2.153, 95%CI: 2.019-2.297), and night waking at least twice (OR=1.193, 95%CI: 1.105-1.288) were statistically associated with central obesity. Conclusion Sleep duration, snoring/asphyxia/suffocation and night waking are associated with overweight/obesity and central obesity.

Objective To set up the proteomic protein profiling of adenomyotic tissue and normal uterine muscle and identify the abnormally expressed proteins in adenomyotic tissue. Methods Samples of adenomyotic tissue (adenomyosis group) and age-matched healthy uterine muscle (control group) were collected from totally 10 patients undergoing transabdominal hysterectomy for adenomyosis and cervical diseases at Peking Union Medical College Hospital from January 2007 to October 2007. The proteomics profiling of adenomyotic tissue and normal uterine tissue were established using two dimensional gel electrophoresis (2-DE) and gel staining method. The differently expressed protein spots were detected by gel comparison using image analysis software and identified using matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS). Results In Coomassie blue stained gels there were on average (512 ± 36) spots and compared with the reference gel the matching rate was 83.7%. In silver stained gels there were (762 +54) spots and compared with the reference gel the matching rate was 81.1%.Compared with normal uterine muscle, there were 15 protein spots disregulated in adenomyotic tissue.Among them 10 protein spots were successfully identified by mass spectrometry. The functions of these disregulated proteins included cell skeleton, oxidation, apoptosis and immune reaction. Conclusions Comparative proteomics analysis is a useful approach for the study of adenomyosis. Compared with normal uterine muscle there are abnormalities in cell skeleton, oxidation, apoptosis and immune reaction. These life processes may participate in pathophysiology of adenomyosis.

Objective Through the dynamical monitoring of the water improvement projects operation,we intend to understand the prevalent trends of endemic fluorosis of children aged 8 to 12 in Hubei,to evaluate the effect of control measures and to provide the basis for making preventive measures.Methods In Hubei,ten surveillance counties were selected,and three epidemic villages were selected as fixed monitoring villages in each county from 2010 to 2014.In those villages,the operation situation of water improvement projects and the fluoride content in drinking water were detected,and the dental fluorosis of children aged 8 to 12 was diagnosed.Results From 2010 to 2014,the normal operation rate of water improvement projects was 75.61％-100.00％,the average of water fluorine content did not change,the differences were not statistically significant (F =2.00,P ＞ 0.05).The numbers of water improvement projects with water fluorine content in excessive amount was increased in the past five years which was only one project in 2010-2012 and was increased to two projects in 2013 and 2014.In 2010-2014,the dental fluorosis prevalence rate of whole children was 9.45％ (525/5 557),the dental fluorosis prevalence rate of exceeding-standard villages of water fluoride content was 42.40％ (92/217),the dental fluorosis prevalence rate of qualified villages was 8.11％ (433/5 340).The children's dental fluorosis prevalence rate of exceeding-standard villages of water fluoride content was higher than that in qualified villages;the differences were statistically significant (x2 =282.60,P ＜ 0.05).Conclusions The operation rate of water-improving projects is mostly higher than 90％,and so is the qualification rate of fluoride content in drinking water.The operation condition and water quality of the water-improving projects in Hubei need to be improved.The prevalence of children dental fluorosis of affected villages has dropped significantly after low fluoride water is provided continuously.

ObjectiveTo study the anatomical abnormalities of basal ganglia and research their influence on depression status in patients with post stroke depression (PSD)by diffusion tensor imaging (DTI) of MRI.MethodsPatients with basal ganglia infarction were recruited,and divided into groups of PSD and non depression control group by Hamilton Depression Rating Scale (HAMD) assessment. All the patients were evaluated with National Institute of Health Stroke Scale ( NIHSS). And the patients were checked by DTI sequence.Fractional anisotropy (FA),average diffusion coefficient (ADC) values and the number of nerve fiber were measured in bilateral caudatum,pallidum,putamen and thalamus.ResultsThe score of NIHSS (6.29 ± 3.45 ) was significantly higher in PSD group than that in non-depression group (3.95 ± 1.90 ;t =2.219,P =0.036). No significant difference was found between the two groups for the DTI data of the basal ganglia nuclei ( t =0.056-1.618,all P ＞ 0.05 ). Compared with contralateral construction (0.40 ± 0.02 ),the FA value decreased in the left putamen ( 0.37 ± 0.03 ) in the PSD group ( t =2.243,P =0.045 ).By Spearman correlations analysis,the HAMD score was positively correlated with NIHSS score ( r =0.464,P =0.017 ),and negatively correlated with the FA values of left pallidum (r=-0.563,P=0.005),right pallidum (r=-0.416,P=0.035) and left putamen (r =-0.428,P =0.029).Conclusions The occurrence of PSD was associated with neurological functional deficit following basal ganglia infarction.The depression level was correlated with the increasing of NIHSS score,the reductions in bilateral pallidum and left putamen FA values.This research contributes to evaluation of the PSD status in patients with basal ganglia infarction.

Objective To investigate and analyze the examination and acceptance results for coalburning-borne endemic fluorosis control and elimination in Hubei Province.Methods A county-level selfinspection and a provincial-level spot-check were conducted to investigate the status of improved-stove usage,the situation of correctly drying corn and chili,and the dental fluorosis prevalence among children aged 8 to 12 in 501 historic coal-burning-borne endemic fluorosis villages of 6 counties (cities) in Hubei Province from 2012 to 2014.The endemic areas were selected according to the Control Standards of Endemic Fluorosis in Endemic Areas (GB 17017-2010) and Eliminating Standards of Coal-burning Type Endemic Fluorosis.Results The results of county-level inspection showed that the qualified rates of improved stoves,the correct-usage rates of qualified stoves,and the correctly drying rates of corn and chili were all higher than 98％ in targeted villages,and the prevalence rate of dental fluorosis of children was 7.73％ (2 319/30 003).The results of provincial-level recheck were more than 99％ and 8.25％ (353/4 277),respectively.The results of county-level inspection were of good consistency with those of provincial-level recheck (88.89％,48/54).Five counties (cities) but one had met the standard of fluorosis control or elimination.Conclusion Coal-burning-borne endemic fluorosis scope in Hubei Province is narrowed greatly and the prevalence rates are decreased significantly.
