Objective: To investigate the status of overweight and obesity and associated factors among primary and middle school students in Huzhou City, Zhejiang Province, so as to provide insights into formulating the prevention and control strategies for overweight and obesity in students. Methods: Primary and middle school students from 5 counties (cities, districts) of Huzhou City were selected by using stratified cluster random sampling method from September to November, 2023. The general information, dietary habits and exercise behaviors were collected using the Student Health Status and Influencing Factors Questionnaire. Height and weight were measured, and body mass index was used to analyze overweight and obesity in primary and middle school students. A multivariable logistic regression model was used to analyze the influencing factors of overweight and obesity. Results: A total of 7 573 students were surveyed, including 3 791 males (50.06%) and 3 782 females (49.94%). There were 2 754 primary school students (36.37%), 2 744 junior high school students (36.23%) and 2 075 senior high school students (27.40%). There were 2 166 students with overweight and obesity (28.60%), 1 186 students with overweight (15.66%), and 980 students with obesity (12.94%). Multivariable logistic regression analysis showed that gender (female, OR=0.546, 95%CI: 0.493-0.604), frequency of sweetened beverage consumption (once and more per day, OR=1.349, 95%CI: 1.102-1.650), and frequency of milk and milk products consumption (less than once per day, OR=0.742, 95%CI: 0.577-0.954) were the influencing factors for overweight and obesity in primary and middle school students. Conclusion The prevalence of overweight and obesity among primary and middle school students in Huzhou City is 28.60%, and is associated with gender, frequency of sweetened beverages and milk and milk products consumption.

OBJECTIVE:To provide reference for rational use of antibiotics to treat Pseudomonas aeruginosa (PA) infection in the clinic. METHODS:Resistant rate of PA in our hospital during 2011-2015 were analyzed retrospectively. Antibiotics use densi-ty(AUD)of 10 commonly used antibiotics were analyzed statistically,and the correlation of resistant rate with AUD was investi-gated by Spearman correlation analysis. RESULTS:One thousaud and eleven strains of PA were isolated in our hospital during 2011-2014,detection rate of PA always occupied the top 5 place. Top 3 antibiotics in the list of AUD were levofloxacin,ceftazi-dime,cefoperazone sodium and tazobactam sodium. AUD of piperacillin sodium and tazobactam sodium,levofloxacin,ciprofloxa-cin and meropenem were positively correlated with resistant rate of PA(r were 1.000,0.900,1.000,1.000,P<0.05). AUD of ce-foperazone sodium and tazobactam sodium were negatively correlated with resistant rate of PA(r=-0.900,P<0.05). AUD of imi-penem and cilastatin sodium,ceftazidime,gentamicin,aztreonam and amikacin had no correlation with resistant rate of PA(P>0.05). CONCLUSIONS:There is correlation between AUD of antibiotics and resistant rate of PA. It is of important significance to detect resistant rate of PA and the use of antibiotics regularly. Antibiotics should be selected cautiously in accordance with bacterial monitoring data,results of drug sensitivity tests,the amount and resistant rate of antibiotics,etc,in order to reduce resistant PA.

This study left flavonoids and alkaloids Chinese herbal monomer with common parent nucleus as cream base carriages drug respectively, cream base were prepared with stable span 60-tween 80 emulsification system. The near-infrared stability analysis technology was performed to quantitatively characterize the physical stability of cream. Base on the theory of gel network structure, theory of emulsification, theory of solubility parameter and theory of double layer, the influence mechanism of Chinese herbal monomer on physical stability of cream was discussed. The results showed that tetrahydropalmatine, matrine and naringenin had similar solubility parameter value with cream base material, creams prepared with those Chinese herbal monomer have higher Zeta potential value and stronger physical stability, and that those creams had similar microstructure information with cream base. However, a larger solubility parameter difference exists between baicalin, baicalein, berberine, palmatine and cream base material. Creams prepared with those Chinese herbal monomers had lower Zeta potential value and poorer physical stability, and that those creams had great different microstructure information with cream base.

AIMTo investigate the effects of protein tyrosine kinase on the inflammation and airway remodeling in lung of guinea pigs with bronchial asthma.

METHODS30 adult male guinea pigs were randomly divided into 3 groups (n=3): control group (C group), asthmatic group(A group)and genistein group (B group). Asthmatic model was established by ovalbumin intraperitoneal injection and ovalbumin inhalation. The total cell and the proportion of inflammatory cell in bronchial alveolar lavage fluid(BALF), inflammatory cell infiltration and index of remodeling of bronchiole were measured, respectively. The expression of p-tyrosine in lung tissue was examined by immunohistochemistry.

RESULTSThe total cell and proportion of eosinophil in BALF of A group were significantly higher than that of C group (P < 0.01), but compared with A group, the total cell and proportion of eosinophil in BALF of B group were much lower (P < 0.01). The number of eosinophile and lymphocyte of bronchiole in A group were significantly higher than that of C group (P < 0.01), but compared with A group, the number of eosinophile and lymphocyte in bronchiole of B group were much lower (P < 0.01). Compared with A group, the remodeling of bronchiole of B group was significantly relieved (P <0.01), there was no difference between B and C group (P > 0.05). Immunohistochemistry indicated that in A group the p-tyrosine was more positively expressed at the bronchial smooth muscle, bronchial epithelium, smooth muscle of vessel and inflammatory cell, especially at smooth muscle of bronchi and vessel and inflammatory cell than that of C group (P <0.01), there was no difference between B group and C group (P > 0.05).

CONCLUSIONPTK played a key role in inflammation and bronchial remodeling in lung of guinea pigs with bronchial asthma. The Protein tyrosine kinase inhibitor genistein could prevent and inhibit the inflammation and bronchial remodeling in lung of guinea pigs with bronchial asthma.

A rare strain of actinomycetes, with broad-spectrum antimicrobial activity, was isolated from the soil samples from the farmland in the area of Yaohu lake in Nanchang. The information about the taxonomic identification, such as the morphology, physiological properties, cell components and 16S rRNA gene se-quences, suggested that the rare strain of actinomycetes was identified as Micromonospora carbonacea.

Based on the strain of Micromonospora carbonacea JXNU-1 with board-spectrum antimicrobial activity, the technology for the isolation and purification of antibiotic from the fermentation broth of the Micromonospora carbonacea, and its physical-chemical properties were studied. The results showed that, the antibiotic was stable under the condition of high temperature and alkali, but not in acid solution. After the pretreatment of centrifugation and filtration to remove the cells and lipids, the antibiotic was absorbed to negative exchange resin, and the impurity was excluded when 2 mol/L NaCl was used as primary eluent. The antibiotic could be eluted with 20% alcohol as eluent, and the eluting speed of the antibiotic was greatly accelerated as 2 mol/L NaCl was added into 20% alcohol as final eluent. Aqueous solution of the antibiotic was yielded from the alcohol-salt eluant by decompression concentration to wipe off alcohol and by dialysis to exclude salt. One active component was detected in antibiotic solution by paper chromatography, and theHPLC purity was over 99%. As the antibiotic shows positive color-forming reaction to Molish reagents, Benedict’s reagents and Diohenvlamine reagents, combined with the characteristics of absorption spectra, it is deduced that the antibiotic belongs to nucleoside antibiotics.

Objective To investigation the pathological characteristics of esophageal squamous cell carcinoma to provide reference criteria for delineating the target area in radiotherapy.Methods Fifty-two patients from the Fourth Hospital of HeBei Medical University underwent resection whom all had been proved to have esophageal squamous cell carcinoma before operation.Chest CT was scanned and transmitted to the 3- dimensional conformal planning system for radiotherapy by VRX-16 scanner.The lesion of esophageal carcinoma was delineated in the 3-dimensional rebuild CT image and the lesion volume was computed by digital rebuild program.Every surgically resected specimen was made into pathologic giant section.The actual size of the specimen was obtained by calculating the size under the microscope with the shrinkage ratio.Multicentric carcinomatous lesion,severe dysplasia and direct intramural infiltration were observed in the giant section with a microscope and the order of such pathological characteristics were analysed statistically.Results 1.The tumor length by different method of preparation of operated specimens differed obviously.The longest was shown by CT. 2.Multicentric carcinomatous lesion was found in 15(29%)cases out of 52 patients.Proximal to the tumor,the mean distance between the multicentric carcinomatous lesion and the main lesion plus the length of the multicentric carcinomatous lesion was 3.02?1.45cm.Distal to the tumor,it was 2.60?2.44 cm.Severe dysplasia was found in 28 patients.Proximally,the mean distance between the severe dysplasia and the main lesion plus the length of the severe dysplasia was 2.45?1.30 cm.Distal to the tumor,it was 3.24?2.19 cm.Direct intramural infiltration was found in 41 patients,of which the mean length being 2.80?1.52 cm proximally and 2.02?1.51 cm distally. 3.Tumor thrombus was found in 6 patients and lymphoduct infiltration in 36 patients.Direct intramural infiltration was found at higher incidence in specimens complicated with lymphoduct infiltration(86%)and those complicated with tumor thrombus(91%).There were no apparent factors affecting severe dysplasia.The proximal distance to direct intra- mural infiltration was much longer than distally.Conclusions Multicentric carcinomatous lesion,severe dysplasia and direct intramural infiltration may be observed in esophageal squamous cell carcinoma.Multicentric carcinomatous lesion and direct intramural infiltration are obviously correlated with lymphoduct infiltration.To cover 95% of the microscopic extension,a margin of 5.0 cm is needed proximal to the base of gross tumor volume,and 7.5 cm distal to it.To cover 90% of the microscopic extension,a margin of 4.5 cm is needed proximally,and 5.0 cm distally.

Objective To explore the influence of inhaled glucocorticosteroid on ?-glutamylcysteine synthetase(?-GCS) in inflammatory cell of sputum in children with asthma.Methods Twenty-two asthmatic children were divided into 2 groups according to treatment.The children who were treated by inhaled budesonide combined with salbutamol were due to group A and the others inhaling salbutamol only were due to group B,the healthy children were acted as healthy control group(group C).The glutation(GSH),total GSH and the activity of ?-GCS in sputum were measured respectively;Expression of ?-GCS in inflammatory cell of sputum were detected by immunohistochemistry;the expression of ?-GCS heavy chain(?-GCS-h) mRNA were detected by reverse transcriptase-polymerase chain reaction(RT-PCR).Results 1.The total GSH[(1.08?0.14) ?mol/L] and oxidized glutathione(GSSG)[(0.37?0.09) ?mol/L] were decreased in sputum of group A of post-treatment compared with pre-treatment(Pa

OBJECTIVESTo research the effects of supracondylar fractures of humerus treated by three different surgical methods.

METHODSThere were 103 patients with supracondylar fractures of humerus including 58 male and 45 female. The age was from 3 to 12 years old with the average of 7.4 years. To divide the cases into three groups by the operative approach in the humerus, the inside approach were in 37 cases (group A), the outside in 35 cases (group B) and the rear in 31 cases (group C). Comparing the reduction of the stretching and bending function of elbow joint and incidence of elbow varus.

RESULTSAll patients were followed-up for 1.5 to 8 years after operation with the average of 32 months. The reduction of stretching and bending function of elbow joint occurrenced in 6 cases in group A, 6 cases in group B and 25 cases in group C, the incidenc of group C were obvious more than group A and B (P < 0.01). The elbow varus occurred in 8 cases in group A, 17 cases in group B and 7 cases in group C, the incidence of group B were obviously more than group A and C (P < 0.05).

CONCLUSIONThere are different effects between three kinds of operative approaches in the humerus. The incidence of outside group is higher on the varus of elbow. The incidence of rear group is higher on the ability of elbow joint stretching and bending. The effect of inside group is sure on the operative approach in the humerus.
