Objective Exploration of TSH, FT3, FT4 changes in critical condition prior to death.Methods 84 patients that were anti-tumor therapy acceptable and not associated with the treatment of thyroid disease in patients with terminal tumors. Age from 24 to 85-year-old, male 56, female 28. The use of SELDI technology (surface-enhanced laser description / ionization time-of-flight mass spectrometry protein chip technology) checks to M/Z for the 11 100 + H～11 900 + H peak of the cluster, divided into the positive group for critically ill patients with early warning protein (LGT) and the negative group for it. All patients were given TSH, FT3, FT4 inspection. The results were statistically analyzed. Results TSH, FT3, FT4 in the LGT positive group was significantly lower than in the negative LGT group. There was no correlation between TSH,FT3 and FT4 in the LGT positive group;In the negative LGT group FT3 and FT4 had a positive correlation,and FT3 and TSH no relevance. Conclusion Thyroid function is normal in the stage of cancer patients stable condition. Possible pituitary-hypothyroidism may occur as the disease advances to the end or before death.This may be an important factor causing the acceleration to the death of the patients. However, the cause and effect between this phenomenon and the early warning of protein fingerprint group(LGT) is still not clear. In critical condition checking thyroid function and render supplementary amount of thyroid hormone in accordance with the checking results may be beneficial.

ObjectiveTo develop a stable model of focal cerebral infarction in rat to study the curative effect of neural stem cells transplantation.MethodsThirty-seven rats were selected which were divided into two groups in random, experimental group and control group. The focal infarction model was developed by the ligation of the left middle cerebral artery followed by the ligation of the ipsilateral common carotid artery and the temporary clip occlusion of the contralateral common carotid artery for 1.5 h. The operation adopted minimally invasive craniotomy though temporal bone. The model was evaluated by examining the neurologic deficits, ink perfusion, TTC staining and Magnetic Resonance imaging.ResultsAll the rats were in good condition after the operation, the mortality rate was 6.25% after 4 weeks. Ink perfusion and TTC staining confirmed that the ischemia was confined to the cortex. The areas of infarction measured 83.52 mm3 by Magnetic Resonance imaging after 4 weeks.ConclusionA stable focal cerebral infarction model can be achieved by minimally invasive craniotomy. It is superior for its homogeneity of infarction volume and site, and its low mortality. It can be used for the study of transplantation of neural stem cells.

To observe the clinical effect of Yisui decoction plus western medicine in treating multiple system atrophy patients, totally 65 patients from China-Japan Friendship hospital during 2008-2012 with complete clinical data and received consecutive traditional Chinese medicine and western medicine treatment for more than 3 months were observed changes of traditional Chinese medicine symptom score, part 1 of unified multiple system atrophy rating scale, orthostatic hypotension before treatment and after 3 months treatment. After 3 months treatment, total effective rate of traditional Chinese medicine symptom was 70.8%. Compared with before treatment, score of part 1 of unified multiple system atrophy rating scale was obviously reduced after 3 month treatment (P < 0.001). Ex- cept swallow function without significant improvement, the remaining projects of unified multiple system atrophy rating scale were im- proved obviously (P < 0.05), of which the most obvious differences were orthostatic symptoms, falls and intestinal function (P < 0.001). Orthostatic hypotension after 1 month treatment and 3 month treatment was obviously better than before treatment (P < 0.001). There was no significant difference in orthostatic hypotension between 1 month treatment and 3 month treatment. The research results show that Yisui decoction plus western medicine has a certain effect on improving clinical symptoms of multiple system atrophy patients, especially has a significant effect on orthostatic hypotension, and can maintain a stable clinical effect in a certain period of time.

Objective To analyze the association of Crohn's disease(CD)with vitamin D receptor(VDR) gene polymorphisms. Methods After collecting 326 CD patients and 464 healthy controls,the four single nucleotide polymorphisms of VDR (FokI, BsmI, ApaI and TaqI) were examined by a SNaPshot technique. Results Compared with those in controls,the frequencies of mutant allele(A)and genotype(GA+AA)of BsmI were significantly decreased in CD patients(both P=0.001). The similar conclusions were also drawn for the mutant allele(C)and genotype(TC+CC)of TaqI(both P<0.05). In further stratified analysis,compared with those in controls,the mutant alleles and genotypes of BsmI and TaqI were significantly reduced in stenotic type CD patients (all P<0.0083). The analyses of linkage disequilibrium(LD)and haplotype showed that BsmI,ApaI and TaqI were in a strong LD,and the formed haplotype AAC was significantly lower in CD patients than that in controls (P <0.05). Conclusions VDR(BsmI and TaqI)polymorphisms are significantly related with the reduced susceptibility to CD,especially for patients with stenotic CD. Moreover,the haplotype AAC might engender a reduced risk of CD.

Objective To analyze the trend of secular growth among the minority girls in China from 1985 to 2005 in order to develop national and local intervention strategies and measures to improve their physical fitness and health.Methods A total of 19 Chinese minoritt girls,including Mongolian,Hui,Zhuang,Korean,Tibetan,Miao,Buyi,Dong,Yao,Bai,Tujia,Hani,Dai,Lisu,Wa,Nakhi,Tu,Qiang and Salar were sampled from the 1985 and 2005 Chinese national surveys to study the students' physical fitness and health.Probit analyses were used to calculate age at menarche (AAM),and the heights and weights of 17-years-old girls in various minority groups.Results From 1985 to 2005,the increments of adult heights and weights increased significantly in many minority groups.The average height of girls aged 17 years old in each minority group had an increase of 150 cm in 2005.Ethnic groups with height growth rates of more than 1 cm per decade in girls aged 17 years old were Korean ( 1.47 cm/decade),Tujia( 1.38 crn/decade),Qiang ( 1.32 cm/decade),Bai ( 1.25 cm/decade),Hui ( 1.13 cm/decade) and Buyi ( 1.07 cm/decade).And the mionority ethnics with weight growth rates of more than 1 kg per decade in girls aged 17 years old were Mongolian ( 1.79 kg/decade),Korean ( 1.69 kg/decade),Tibetan ( 1.66 kg/decade),Nakhi ( 1.39 kg/decade),Qiang ( 1.28 kg/decade) and Hui ( 1.10 kg/decade).The overall AAM showed a downward rate in all the 19 minority groups,but with different degrees.Tujia,Yao and Nakhi showed the largest reductions,with AAMs as 2.15,1.76 and 1.38 years earlier in 2005 than in 1985,respectively.Conclusion Our data suggested that the downward secular trend in AAMs and the increments of adult heights might reflect the secular growth change in the major minority groups during the past 20 years,but there was an obvious disequilibrium of puberty development and increments of heights in adults between the minority groups.

AIM: To observe the changes in subfoveal choroidal thickness ( SFCT ) after intravitreal injections of ranibizumab ( IVR ) for macular edema secondary to retinal vein occlusion ( RVO) .
METHODS:Thirty-six eyes of 36 patients with macular edema secondary to RVO) were treated with 0. 5mg IVR monthly for 3mo and received additional IVR as needed over the following 1a period. SFCT of the all eyes ( the affected eyes with RVO and unaffected fellow eyes ) was measured by enhanced depth imaging optical coherence tomography images before and after the IVR.
RESULTS: The mean SFCT of the affected eyes with RVO decreased from 246. 7±115. 0μm at baseline to 220. 5±102.0μm at 1mo (P<0.05), 198.3± 114.0μm at 6mo (P<0.01), 212. 6± 96. 0μm at 12mo (P<0. 01). Whereas the fellow eyes changed from 229. 4±108. 0μm at baseline to 226. 3±107. 0μm at 1mo (P>0. 05), 228. 6±127. 0μm at 6mo (P>0.05), 223.6±101.0μm at 12mo(P>0.05). There were statistically significant difference between affected eyes with RVO and unaffected fellow eyes.
CONCLUSION: The SFCT is decreased after IVR for macular edema secondary to RVO. IVR seems to affect the hemorheology of the choroid.

Objective To identify the changes of morphological development status on minority students in China from 1985 to 2005. Methods We selected a total of 15 groups of the Chinese minority students as subjects of the study, including Mongolian, Hui, Uygur, Zhuang, Korean, Tibetan, Yao, Li, Qiang, Buyi, Dong, Miao, Tu, Salar, Kirgiz, with data from the Chinese national survey on students' physical fitness and health condition in 1985, 1995, 2000 and 2005. Height, weight and waist of the subjects were calculated and analyzed. Results From 1985 to 2005, the growth and characteristics of height in the Chinese minority students had a similar increase when comparing to the Han students, but with different degrees. However the growth rate was gradually decreasing. The average heights of Kirgiz, Korean, Salar and Mongolian schoolboys aged 18 years old were 170 cm, being 170.91 cm, 170.47 cm, 170.29 cm and 170.27 cm, respectively, which were close to that of the Hart students. Some minority students had a substantial increase of body weight. However, the waist of some minority students decreased. Only a few groups of minority students had increasing waist, such as Mongolian and Korean rural boys, Mongolian, Zhuang, and Korean rural girls, with the growth being 0.101 cm, 0.095 cm, 0.126 cm, 0.163 cm and 0.107 cm, respectively. Uygur, Mongolian, Kirgiz and Korean students had the morphological development similar to Han urban students, especially Uighur boys and girls. Conclusion From 1985 to 2005, The height, weight and waist of Chinese minority students had an overall increase at different degrees. In order to improve the physical fitness of minority students, awareness on nutrition and health education of both students and parents should be strengthened. Surveillance and programs on growth, development and health status of the minority children and adolescents should also be carried out continuously.

Objective To describe the characteristics of sexual debut among college students in China to provide appropriate sex education in that population. Methods An anonymous questionnaire survey was conducted among 33 653 college students selected by multi-stage stratified cluster sampling method in 18 provinces and cities of China. Results The percentage of students who had initiated sexual intercourse before age 14 was 1.9%. Overall, male students (2.8%) were significantly more likely to have initiated sexual intercourse before age 14, than female students (1.1%). The percentage of students who had initiated sexual intercourse from age 15 to 18 was 6.4% in males versus 2.1% in females. while the rates of students who had initiated sexual intercourse after age 19 were 6.9% in males and 2.6% in females. The first sexual intercourse was significantly associated with parental educational attainment, geographic location and family structure. Students whose parents were relatively well educated, living in the western areas of the country China, or with nucleus/extensive families were more likely to have early sex in their puberties. Conclusion Sexual education should be strengthened especially in the western areas, and targeted on the students whose parents with relatively higher educational background or who were from extensive families.
