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 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 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 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.

OBJECTIVETo explain the essence of pungent-hot herb property express according to in vivo and in vitro studies on its effect on calmodulin on the base of the observation of the adjustment in hypothalamic-pituitary-gonad axis functions of Aconiti Lateralis Radix Praeparata, Curculiginis Rhizoma, Cinnamomi Cortex and bitter-cold herb Phellodendri Chinensis Cortex in rats under the state of yang deficiency.

METHODThe yang-deficient model was duplicated by intramuscularly injecting hydrocortisone sodium succinate powder injection. After the intervention with Aconiti Lateralis Radix Praeparata, Curculiginis Rhizoma, Cinnamomi Cortex and bitter-cold herb Phellodendri Chinensis Cortex for seven days, TSH, T3, T4, 17-OHCS, COR, T, E2 of hypothalamus-pituitary-target gland axis and other relevant indexes were detected. The calmodulin expression in livers and L02 cells cultured in vitro was detected by using Western blot.

RESULTPungent-hot herbs Aconiti Lateralis Radix Praeparata, Curculiginis Rhizoma, Cinnamomi Cortex can significantly correct indicators of hypothalamic-pituitary-gonad axis and calmodulin, whereas the bitter-cold herb Phellodendri Chinensis Cortex showed no obvious effect.

CONCLUSIONThe pungent-hot herb property expression may be closely related to calmodulin.

In chronic kidney disease (CKD), inflammatory responses during the progression of renal tissue and tissue injury related causes its progression to end-state renal disease. Among them, nuclear factor (nuclear factor, NF)-kappaB signaling pathway by regulating the corresponding nuclear expression of target gene transcription, as well as affecting the synthesis of inflammatory mediators, induction of inflammation lead to kidney damage and renal fibrosis. Some single herbs and their extracts (such as Astragali Radix, Scutellariae Radix, Ginkgo Folium) and some traditional Chinese medicine (such as Danggui Buxue decoction, Qilian decoction) can reduce the inflammatory damage induced by renal tissue NF-kappaB signaling pathway and delay the progression of CKD.

Objective To explore the effect of different cold ischemia (CI)times on the patterns of intra-graft T cell activation gene-3 (TCA-3) expression early after isogeneic half liver transplantation (PLT)in mice. Methods The models of C57BL/6 full-size(FS) and PLT were established.The CI time was 1,4 and 8 h.Specimen were collected at 4 and 24 h post-reperfusion.Ribonuclease protection assays (RPA)was used to evaluate serial mRNA expression of the TCA-3 chemokine in all mice.Histopathology was used to examine cold ischemia injury in the liver grafts. Results A total of 45 control and 30 PLTs were performed.The survival rate at 7 day after control and PLT was 100％.Quantitative analysis demonstrated the levels of TCA-3 mRNA expression were low at 4 h after reperfusion in control group with 1,4,8 h CI.The levels of TCA-3 significandy increased at 4 h after reperfusion in PLT group with CI of 1,4,8 h and the difference between the two groups was statistically significant ( F =7.41,P ＜ 0.05 ). TCA-3 mRNA expression significantly decreased at 24 h after reperfusion in two groups. But the difference was not statistically significant ( P ＞ 0.05 ). Histopathology showed severer cold ischemia injury in PLT grafts compared with control grafts. Conclusions The expression of TCA-3 significandy increased early after PLT and played an important role in cold ischemia injury.TCA-3 could be used as the early therapeutic target for reducing ischemia injury in PLT grafts.

Objective To study the expressions of Cx43,CD105 and VEGF in HBV related HCC tissues and the relationships between Cx43 expression and recurrence and prognosis after cancer radical resection in HCC patients stratified by serum AFP levels. Methods The expressions of Cx43,CD105,VEGF in 234 HBV related HCC tissues were examined by tissue microarray and two-step methods of PV-6000 of immunohistochemistry and the expressions of Cx43 in 20 frozen HCC specimens were examined by RT-PCR. Results Cx43 in HCC tissues was positive as examined by both immunohistochemistry and RTPCR methods.Positive Cx43 expression is correlated with lower early recurrence ( Log Rank P =0.001 ),longer disease free survival (Log Rank P =0.026 ) and overall survival( Log Rank P =0.000 ) as showed by the Kaplan-Meier analysis in patients with AFP ＜ 400 μg/L. The expression of Cx43 is an independent prognostic factor.The positive expression of Cx43 related with lower positive expression of CD105 and VEGF (P =0.018,0.023 ),and correlated with histological differentiation (P =0.002),the number of focus (P =0.033 ),blood vessel tumor embolism ( P =0.029 ). Conclusions The expression of Cx43 is correlative with the expression of CD105 and VEGF,and is predictive of HCC early recurrence and poor prognosis after radical hepatectomy in HBV related HCC patients with serum AFP ＜ 400 μg/L.

Objective:To compare the efficacy of bilateral and unilateral metallic stenting in the treatment of unresectable malignant hilar biliary obstruction.Methods:From January 2012 to December 2018, a total of 300 patients with malignant hilar biliary obstruction (Bismuth type Ⅱ-Ⅳ) were treated with endoscopic metallic stenting in Oriental Hepatobiliary Surgery Hospital. Ninety-four patients with bilateral metallic stenting (bilateral metallic stent group) and 94 patients with unilateral metallic stenting (unilateral metallic stent group) were matched and analyzed by propensity score matching. The clinical success rate, the total number of interventions, the stent patency and overall survival time were compared between the two groups.Results:The clinical success rate in the bilateral metallic stent group was significantly higher than that of the unilateral metallic stent group [98.9% (93/94) VS 78.7% (74/94), χ2=19.352, P<0.001], and the mean number of intervention in the bilateral metallic stent group was significantly less than that of the unilateral metallic stent group (1.2±0.5 times VS 1.7±0.9 times, t=-4.345, P<0.001). The stent patency time in the bilateral metallic stent group was significantly longer than that of the other group [10.0 (8.0, 12.1) months VS 5.7 (5.2, 6.3) months, χ2=19.789, P<0.001]. The median survival time of patients in the bilateral group was numerically longer than that in the unilateral group, but did not reach statistical significance [7.6 (6.3, 8.9) months VS 4.6 (3.7, 5.7) months, χ2=3.628, P=0.057]. Conclusion:Endoscopic bilateral metallic stenting is superior to unilateral metallic stenting in the clinical management of malignant hilar biliary obstruction unsuitable for surgery.

Objective:To investigate the feasibility and efficacy of endoscopic placement of transpapillary parallel-style bilateral metal stents for malignant hilar biliary stricture.Methods:A total of 55 patients with malignant hilar biliary stricture (Bismuth Ⅱ-Ⅳ) were treated with an improved endoscopic drainage technique (endoscopic transpapillary parallel-style bilateral metal stenting) from January 2012 to December 2018 in Shanghai Oriental Hepatobiliary Surgery Hospital. The technical success rate, clinical success rate, incidence of complications, success rate of endoscopic re-intervention, stent patency and overall survival were analyzed.Results:The technical success rate of endoscopic placement of bilateral metal stents was 96.4% (53/55), the clinical success rate was 96.2% (51/53), and the early complication incidence was 13.2% (7/53). The median stent patency was 9.2 months (95% CI: 8.0-10.3 months), the success rate of endoscopic re-intervention of bilateral biliary systems was 92.3% (12/13), and the median overall survival was 6.7 months (95% CI: 4.7-8.8 months). Conclusion:This modified technique of bilateral metal stent placement is safe and effective for malignant hilar biliary stricture that is unsuitable for surgery.
