BACKGROUND: "Public Health Report in 2000" shows that various indexes of body shape of the national infants increase with their age; Urban infants exceed rural even-aged ones in the body height, body mass and chest circumference; Urban infants also exceed rural even-aged ones in the mean increase of development of body shape at each index. Urban-rural disparity still exists.OBJECTIVE: To investigate the body shape of 3- to 6-year-old infants of Heibei province, and analyze the differences in body shape at different age stages between urban and rural infants.DESIGN: Cross-sectional survey.SETTING: Hebei Provincial Party School.PARTICIPANTS: Body-shape investigation was performed in 1 600 healthy 3- to 6-year-old urban and rural infants from Shijiazhuang,Cangzhou and Chengde in July 2000 with clustering stratified random sampling. Informed consents were obtained from the guardians of the infants.METHODS: By referring to related results, the body length and body mass at born of infants were investigated through questionnaire-style according to the performance criteria of "Public Health Monitoring Working Manual in 2000" formulated by general administration of sport of China.To be measured shape indexes included body height, body mass, sitting height, chest circumstance, skinfold thickness at upper buttocks, shoulder blade and abdomen, t test was used for the comparison of difference of measurement data.RESULTS: Totally 1 600 questionnaires were handed out, and all of them were completely and exactly filled in and retrieved. 800 were male and 800 were female; 800 were urban infants and 800 were rural infants. ① The body height and body mass of 3- to 6-year-old infants at born: Four year-old male infants were shorter than other age-stage infants at born. Six-year-old male infants were the longest, and the increased amplitude was the largest and the increased speed was the fastest. The body height of female infants developed in wave-tendency from born, decreased at 5 years old and rebounded at 6 years old. The body mass of male infants developed in wave-tendency, and decreased fastest in the largest amplitude at 6 years old. The body mass of female infants developed in year-by-year decreasing tendency. The increased amplitude and speed of the body mass of the female infants were the same between at 5 yearn old and at 6 years old. ② The changes in body height and body mass of 3- to 6-year-old infants: The body height and body mass of 3- to 6-year-old infants increased with age.③ Comparison of the measuring index of body shape between urban and rural 3- to 6-year-old infants: The urban male infants significantly exceeded the rural male ones in chest circumstance, skinfold thickness at upper buttocks, shoulder blade and abdomen [(55.22±3.56)vs(54.58±3.43) cm;(9.33±3.20)vs (8.34±2.29) mm;(6.19±2.55)vs (5.18±1.98) mm;(6.64 ±3.30)vs (6.05±2.49) mm, t=2.573, 5.034,2.375, 2.848,P ＜ 0.05-0.01].The body height, body mass and sitting height were close between urban and rural male infants (P ＞ 0.05). ④ Comparison of the measuring index of body shape between urban and rural 3- to 6-year-old female infants: Urban female infants significantly exceeded rural female ones in skinfold thickness at upper buttocks, shoulder blade and abdomen [(10.09±3.32) vs (9.08±2.52) mm, (6.68±2.45) vs (6.16±2.01) mm, (7.62±3.23) vs (6.84 ±3.07) mm, t=4.857, 3.266,3.481 ,P ＜ 0.01].The body height, body mass,sitting height and chest circumstance were close between urban and rural female infants (P ＞ 0.05).CONCLUSION: ①Male and female infants have the largest increased amplitude and fastest increased speed in the body height between at 3 years old and at 4 years old. Increased amplitude and increased speed develop constantly from 4 years old. ② The body mass of male infants had the largest increased amplitude at 6 years old, but that of female infants at 4 years old. The increased speed of body mass of male infants is higher at 4 years old and 6 years old than at 5 years old, and that of female infants increase with age. ③ Urban male nfants exceed rural male infants in upper body development and in vivo fat content. In vivo fat content of urban female infants is higher than that of rural ones.

BACKGROUND: Officers and intellectuals are bearing heavy government affairs and tasks of teaching and scientific research. It is practically important to acknowledge and master their body constitution, which can help to instruct them to scientifically build their bodies.OBJECTIVE: To investigate the body function and shape as well as body constitution of scientific researchers and officers in Handan, and analyze the existing problems and bring out the settlement.DESIGN: Cross-sectional study.SETTING: Hebei Provincial Committee Party School.PARTICIPANTS: A total of 499 subjects, aged 20-59 years, including238 males and 261 females were selected from government officers, university teachers and scientific researchers of institute and aeademy by using stratified and cluster random sampling. Subjects aged 20-39 were divided into adult group A (50.5%), and those with the age ranged 40-59 were taken as adult group B (49.5%).METHODS: All subjects fulfilled the questionnaire (including whether they had hospitalized history, and the smoking condition, exercise condition, reasons why did not participate in the sports, sports items that patients took part in, the place they conducted athletic activities, time of each exercise and exercise times per week etc.) and were measured of the body constitution.MAIN OUTCOME MEASURES: ①Indexes of body function and shape,including body height, body mass, chest circumference, waistline, hip circumference and skinfold at all parts of body as well as the pulse in quiet state, systolic blood pressure (SBP), diastolic blood pressure (DBP) and lung capacity etc. ②Indexes of body constitution, including grasp force,bend-ahead in sitting, stand up on one leg with eyes closed, choice reaction time simple reaction time, back strength, 10 m×4 shuttle run, and pushup (male)/sit-up (female) etc. The results of test were scaled according to the Report of Monitoring of Chinese Adult Constitution, edited by the State Physical Cultural Administration. Those with the score greater than 17 points passed, while those less than 17 points failed.③The relationship between status quo of body constitution and life style.RESULTS: A total of 499 subjects were involved in the analysis of results.①With the age increasing, the body mass in males and females were increased with circumferences being enlarged and subcutaneous fat increased, and the shape was in horizontal development. The body function in females with the age ranged 20-40 were relatively stable, and began to descend at 40. The body function in adult males descended gradually and stably with the descending speed lower than in females. The force, bursting strength of lower limbs, position sense, coordination of sight and proprioceptive sense, speed in motion and response etc. Of adult males were better than males, while the extensibility and tenacity of joint, muscle and tendon were superior in females than in males. All indexes of constitution in males aged 20-40 were better, while the tenacity and speed in motion and response of males older than 40 began to decay rapidly. ②The pass rate in males of adult group A was 87.5% and was 87.3% in females, while that in males of adult group B was 80.2% and was 74.8% in females. ③The pass rate in populations with exercise custom was greatly higher than in those without it, while the proportion of exercise people accounted little in the subjects. It accounted for 40.7% in males of adult group A and for 28.6% in females, and it accounted for 37.3% in males of adult group B, and for 31.6% in females. ④Body constitution in people who never smoke and occasionally smoke were better than in those often smoke. The pass rate in people who had been hospitalized was a little lower. ⑤The pass rate in subjects who exercised three or four times each week was much higher,and it was the highest in subjects exercised 30-60 minutes each time.CONCLUSION: ①The constitution in population older than 40 is significantly worse and worse. ②Sports activities can remarkably promote the body constitution.③Smoking has obvious side effects on body constitution.④It can reinforce the body constitution by doing sports activity for 30-60 minutes and 3 or 4 times each week.

OBJECTIVE To study air disinfection methods in unremitting operating room,we compared effect of using trioxide disinfector(used in operating room "A") with YKX/G100-type medical air disinfection and purification machine(used in operating room "B") in disinfecting air inside unremitting operating room.METHODS To observe the killing effect on air natural bacteria of the two methods,we used natural sedimentation monitoring the different stages sampling before and after sterilization and at the beginning stage of the unremitting operation.RESULTS Both the two methods could achieve the air natural bacteria eradication rate above 85%.The air bacteria colony number obviously upgraded after the beginning of unremitting operation in operating rooms "A";but in operating rooms "B",the number fell-off slowly.CONCLUSIONS The medical air disinfection and purification machine can shorten the interval of operations,it is the better approach of continuous air disinfection in solving the unremitting operating room with personnel existence.

A retrospective survey wag performed among medical staff in a hospital during 2006-2008 with physical examinations and reviews of medical records.Nonalcoholic fatty liver disease(NAFLD)related factors were compared and analyzed for them.Overall detection rate of NAFLD was 13.9%(230/1655)in 2006 and 18.9%(344/1817)in 2008,with statistically significant difference(χ2=15.549,P＜0. 01 ). Among people surveyed over 30 years old, detection rate of NAFLD was 9.4%, 17. 8% and 21.7% for those aged 30 -39, 40 -49 and 50 years and over, respectively in 2006, while 14. 4%, 28. 2% and 30. 5% , respectively in 2008. Detection rate presented a increasing trend in those of younger age. Relative risk for fatty liver was 1. 859 for those with obesity and overweight. Prevalence of NAFLD in medical staff increases year by year. Medical staff should attend for their own health and take measures to prevent them from its potential risk factors and pay more attention to behavioral intervention for NAFLD.

Objective To observe autonomic nerve function damage in diabetic patients with gastrointestinal symptoms. Methods Twenty-four patients of diabetes mellitus (DM) with gastrointestinal symptoms, as well as 20 cases of DM without gastrointestinal symptoms and 17 health volunteers were recruited from the clinic of gastroenterology, Jishuitan Hospital, Beijing during December 2008 to May 2009, and standard cardiovascular reflex test was performed for all of them to determine their functions of the autonomic nerve. Results Respiratory rate (an indicator of parasympathetic nerve function) was ( 14 ± 5 ) times per minute in patients of DM without dyspepsia, obviously lower than that in healthy controls [(20±10) times per minute], and that in patients of DM with dyspepsia was (9 ±6) times per minute, obviously lower than that in healthy controls and asymptomatic ones ( P ＜ 0. 05 ). Scores of five indicators of the autonomic nerve functions, and the sympathetic, parasympathetic nerve and overall autonomic nerve functions were significantly higher in patients of DM with gastrointestinal symptoms than those in the patients without dyspepsia and healthy controls. Abnormality rate of autonomic nerve functions was 96 percent (23/24) in the patients with dyspepsia, 58 percent (14/24) in those definitely and seriously involved, and five percent (1/20) in those without dyspepsia. Conclusions Autonomic neuropathy exists in most diabetic patients with dyspepsia, both sympathetic and parasympathetic nerve involved. Impairment of parasympathetic nerve function occurs earlier than that of sympathetic nerve in patients of DM.
