The strategic cost management of the hospital means setting the cost management of the hospital in the realm of strategic management and analyzing the hospital and its cost behavior and structure from a strategic level so as to create advantages in competition, attain the goal of adapting the hospital to the continuously changing environment and facilitating stralegic management. Strategic cost management is characterized by a protracted, overaU, extensional and innovative nature and methods for it include value chain analysis, strategic positioning analysis, cost agent analysis and many others. Clarifying the goals of strategic cost management, selecting different strategies according to strategic cost information, perfecting the cost management of the hospital and enhancing cost awareness, and giving play to the functional role of economic management personnel are some of the prerequisites for the hospital to implement strategic cost management.

The paper first analyzes the intrinsic need for cultural integration in hospital regrouping and sums up its content, including the integration of values, management ideas, institutional cultures and institutional frameworks. It then introduces some methods of cultural integration in hospital regrouping, such as running in on the basis of respecting human nature, resolving conflicts on the basis of being mutually tolerant, and merging completely on the basis of optimizing means of integration. The paper points out that success or failure of cultural integration in hospital regrouping depends on the thinking of the leaders. For this reason, it is imperative to enhance integration awareness and improve integration capability.

Objective:To analyze the secular trends of height among Chinese students aged 17 in dif-ferent ethnic minorities from 1985 to 2010. Methods:A total of 18 Chinese ethnic minorities’ students, including Mongolian, Hui, Uygur, Zhuang, Korean, Tibetan, Miao, Buyi, Dong, Bai, Tujia, Hani, Dai, Lisu, Wa, Nakhi, Tu and Qiang as subjects were sampled from the 1985, 1995, 2000, 2005 and 2010 Chinese National Surveys on Students’ Constitution and Health. The heights of 17 years old people by gender in various ethnic minorities were analyzed and compared. Results:From 1985 to 2010, the in-crements of adult heights increased significantly in many ethnic minorities’ boys. In 2010, the average height of boys aged 17 years in each minority group was higher than 162 cm and was higher than 170 cm among boys from Hui, Mongolian and Korean groups. The ethnics with height growth rates of more than 2 cm per decade in boys were Hui (2. 64 cm/decade) and Dong (2. 05 cm/decade) and the ethnics with height growth rates of more than 1 cm per decade were Korean (1. 99 cm/decade), Tibetan (1. 90 cm/decade), Hani (1. 80 cm/decade) and the other 9 minority groups. The average height of girls aged 17 years in each minority group was higher than 150 cm in 2010 . The heights showed an upward trend in 15 minority groups, but with different degrees. The ethnics with height growth rates of more than 1 cm per decade were Hui (1. 56 cm/decade) and Korean (1. 29 cm/decade). The increments that were signifi-cant between 1985 and 2010 were Hui (3. 89 cm), Korean (3. 23 cm), Dong (2. 35cm) and the other 6 minority groups ( P<0 . 05 ) . Conclusion: Our data suggest that the increments of adult heights may reflect the secular growth change in the major minority groups during the past 25 years, but there was an obvious disequilibrium among various ethnic minorities. We should pay more attention to the minority groups with poor growth and give them more help. Meanwhile, we should also pay attention to the nega-tive effects of the secular growth trend on those minority groups with fast increasing adult height.

Objective:To analyze the current situation of age at menarche ( AAM) in Chinese ethnic minority girls aged 9 -18 years, and compare the AAM with that of Chinese Han girls from the same province or autonomous region .Methods:Probit analyses were used to calculate the AAM in various eth-nic minority groups of Chinese girls who participated in 2010 National Physical Fitness and Health Sur-veillance .The sample size of ethnic minority girls was 31 711, and the ethnic minorities were Mongolian , Hui, Tibetan, Uighur, Miao, Yi, Zhuang, Buyi, Korean, Dong, Yao, Bai, Tujia, Hani, Kazak, Dai, Li, Lisu, Wa, Shui, Dongxiang, Naxi, Kirgiz, Tu, Qiang and Sala.The local Han girls to compare with the AAM were also surveyed in 2010 National Physical Fitness and Health Surveillance .Results:In the 13-year-old group, the percentage of menarche in Sala was the lowest (32.17%), while that in Korean was the highest (93.23%).At the age of 18, 99.60%ethnic minority girls appeared menstruating .The AAM of the top 3 ethnic minority groups were Korean ( 11 .79 years ) , Mongolian ( 12 .44 years ) and Zhuang (12.52 years); and the last 3 ethnic minority groups were Dongxiang (14.36 years), Sala (14.32 years) and Shui (14.02 years).The AAM in Korean was 0.93 years earlier than that of the Han girls from Jilin province;the AAM in Mongolian was 0 .14 years earlier than that of the Han girls from Neimenggu autonomous region;the AAM in Naxi and Qiang was close to that of the Han girls in the same province (region) (P>0.05);and the AAM in Hui, Uighur, Miao, Yi, Zhuang, Buyi, Dong, Yao, Bai, Tujia, Hani, Kazak, Dai, Li, Lisu, Wa, Shui, Dongxiang, Kirgiz, Tu, and Sala was later than that of the Han girls in the same province ( region) .The cluster analysis indicated that the 26 ethnic mi-nority groups could be classified as three groups: Korean were classified into the earlier age group of AAM;Dongxiang, Sala, Uighur, Yi and Shui belonged to the later age group of AAM;and the other 20 ethnic minority groups were into the middle age group of AAM .Conclusion:There was a large variation among different ethnic minority groups in China .The AAM was earlier in Korean , and Mongolian , com-pared with the local Han girls , and the AAM in other ethnic minority groups was the same or later com-pared with the local Han girls .

Objective:To analyze the prevalence of anemia and its proportions of severity,and to exa-mine the association between anemia and nutritional status among Chinese students of ethnic minorities, so as to provide bases for the prevention and treatment of anemia.Methods:The subjects were Mongoli-an,Hui,Zhuang and Korean students aged 7,9,1 2,1 4 and 1 7 years,sampled from the 201 0 Chinese National Surveys on Students’Constitution and Health.World Health Organization (WHO)criteria for screening anemia (2001 )was used,and the proportion rates of mild,moderate and severe were ana-lyzed.The nutritional status was defined according to the growth references of body mass index (BMI)-for-age z-score for 5 -1 9 years developed by the WHO.Stepwise Logistic regression was used to assess the association between anemia and nutritional status,gender,urban /rural areas,age and ethnic minori-ties.Results:The prevalences of anemia were 4.4%,26.4%,6.6% and 5.8% in Mongolian,Hui, Zhuang and Korean students,respectively,of whom,the prevalence of anemia was highest in rural girls and reached 4.8%,42.0%,9.0% and 6.7%,respectively.Most of the ethnic minorities’students belonged to mild anemia,and the prevalence of severe anemia was 1 .4%,1 2.9%,1 .6% and 1 .9% in Mongolian,Hui,Zhuang and Korean students,respectively.Stepwise Logistic regression showed that the girls,rural students,students aged 1 2 years and 1 7 years,Hui,Zhuang and Korean students were more likely to develop anemia than the boys,urban students,students aged 7 years and Mongolian students. The overweight students were less likely to develop anemia compared with the normal students and there was no significant association between anemia and thinness or obesity when the other factors were con-trolled (P >0.05).Conclusion:The epidemic of anemia was different in the different ethnic minorities and the prevalence of anemia in Hui students was of moderate public health concern according to the WHO’s criteria.We should pay more attention to the prevention and treatment of anemia for Hui and eth-nic minorities in rural areas,especially for rural girls.The nutritional status of students could not be a ba-sis or judgement for anemia as there was no significant association between anemia and nutritional status.

Objective: To analyze the prevalence of reduced visual acuity (VA) and to examine the association between reduced visual acuity and influencing factors among Chinese Han students, so as to provide bases for the prevention and treatment of reduced visual acuity.Methods: Subjects were from 2014 Chinese National Surveys on Students' Constitution and Health (CNSSCH).In this survey, 261 832 Han students aged 7-22 years participated.Unaided distance VA was measured using a retro-illuminated lgMAR chart with tumbling-E optotypes.Ametropia was determined by using serial bronchoscopy.Logistic regression was used to assess the association between reduced visual acuity and influencing factors.ArcMap 10 was used to map the regional distribution of reduced visual acuity.Results: Nationwide, the overall prevalence of reduced visual acuity was 66.6%, and was highest among the urban girls (73.5%).The prevalence of myopia was 60.8% and accounted for more than 90% among the students with reduced visual acuity.Compared with 2010 CNSSCH, the increments of reduced visual acuity were highest in the students aged 13-15 years (6.8 percentage points).The prevalence of reduced visual acuity ranged from 50.6% to 76.2% in each province (autonomous region, municipality) in 2014 CNSSCH.The top three of the prevalence of reduced visual acuity were Jiangsu (76.2%), Zhejiang (76.0%) and Shandong (75.9%), and the lowest three were Hainan (50.6%), Guizhou (53.9%) and Xinjiang (57.6%).Logistic regression showed that the girls, urban students, and students who spent ≥2 h per day in their after school homework were more likely to develop reduced visual acuity, but the students with physical activity time ≥2 h per day were less likely to develop reduced visual acuity.Conclusion: Although the situation was different in each province (autonomous region, municipality), reduced visual acuity has become a public concern affecting the health of students in China.Based on the intervention on the key populations, such as urban girls and pre adolescent students, we should also continue to strengthen the prevention and control for reduced visual acuity among all students.

Objective: To study the association of dopamine ?-hydroxylase gene 5′ flanking region polymorphism -1021 C→T with attention deficit hyperactivity disorder (ADHD) in Han children. Methods: ADHD was diagnosed according to the DSM-Ⅳ criteria . DNA was extracted and PCR was performed to examine the DBH-1021C→T polymorphism. HHRR was used to test the association of dopamine ?-hydroxylase gene with different subtypes of ADHD. Results: HHRR results showed this polymorphism had a tendency to be associated with the inattention subtype (P=0.067) and the combined subtype (P=0.076). The T allele was the protective factor of the inattentive subtype (P= 0.07), and the risk factor of the combined subtype (P=0.08). After dividing the 292 nuclear families according to sex, DBH-1021C→T polymorphism was found to be associated with the combined subtype (P=0.04) with the T allele as the risk factor (P=0.02). There were no positive findings among the girl nuclear families of ADHD. Conclusion: DBH gene is related to ADHD combined subtype and inattention subtype. The genetic basis of ADHD combined subtype and is inattention is different, and is influenced by sex factor.
