Objective To evaluate the nutritional status of iodine of pregnant and lactating women in coastal and inland areas of Zhejiang province,and to provide scientific basis for iodine supplementation.Methods In 2009,five coastal cities,five coastal counties and three inland areas from Zhejiang province were selected by the cluster sampling method,and one sub-district(township) was randomly selected in each city (county),then one community (village) was randomly selected in each sub-district (township).Thirty pregnant women,thirty lactating women and fifty children aged 8 - 10,were randomly selected in each community(village) as the investigation objects to collect instant urine samples to detect urine iodine,and to collect thirty resident edible salt and some water samples to detect salt iodine and water iodine,if the numbers of water source were more than 5 then 1 water sample was collected by their location of east,south,west,north and center in each community(village),otherwise,the numbers of water samples collected were equal to the number of community (village).Results The medians of salt iodine of coastal city,coastal county and inland area were 28.42,25.29,and 33.24 mg/kg,respectively,and the medians of water iodine correspondingly were 5.41,11.52,and 2.80 μg/L,respectively.The medians of urinary iodine of pregnant and lactating women in Zhejiang province were 148.72 and 161.34 μg/L,respectively,which were less than that of children aged 8 - 10(231.02 μg/L,Z =8.57,8.24,all P ＜ 0.017).The medians of urinary iodine in pregnant women from different areas were ranked in order as inland areas(211.42 μg/L),coastal counties (150.51 μg/L) and coastal cities (123.33 μg/L,Z =2.80,5.31,2.42,all P ＜ 0.017),and in lactating women,the medians of urinary iodine in inland areas( 197.43 μg/L) was higher than that in coastal cities( 139.64 μg/L,Z =4.03,P ＜ 0.017).Conclusions The overall levels of iodine nutrition in lactating and pregnant women in Zhejiang province are in the appropriate level,but that of the pregnant women in the coastal cities is inadequate.

OBJECTIVETo study surgical techniques for degenerative lumbar scoliosis associated with lumbar stenosis and evaluate their clinical significane.

METHODSThirty-two patients with degenerative lumbar scoliosis associated with spinal stenosis were treated by techniques of posterior lumbar interbody fusion or posterolateral fusion and pedicle screws. There were 18 male and 14 female with 56.8 years old on the average (ranging from 49 to 75 years). There were no evident change of lumberlordosis in 15 cases, and lumber lordosis were obvious loss associated with lumbar subluxation in 17 cases. The correcting, the improvement of back and leg pain, complications and followed-up results were analyzed retrospectively.

RESULTSThirty-two cases were followed-up for 6 to 39 months (the average time of 13 months). The average correction rate of scoliosis was 58.0% and the rate of pain relief was (80.2 +/- 5.8)%. There were two cases of dura sac laceration, two cases of nerve roots injury and a case of pseudoarthritis. During followed-up, correction rate and height of disc spaces were not lost. Shift of interbody cages were no displaced; all the internal fixation got well fusion and the rate of fusion for the bone graft was 96.9%.

CONCLUSIONPosterior pedicle screws combined with interbody fusion or posterolateral fusion is a safe and effective surgical treatment for degenerative lumbar scoliosis associated with lumbar stenosis.

Objective To evaluate the dietary iodine intake level of population in coastal and inland areas of Zhejiang province.Methods The cluster sampling method was applied to select Zhoushan,Ningbo and Taizhou cities from Zhejiang province as coastal areas,to select Jinhua,Quzhou and Lishui cities from Zhejiang province as inland areas,and two counties(districts) were randomly selected in each chosen city,three sub-districts(towns) were randomly selected in each chosen counties (districts),then one community (village) was randomly selected in each chosen sub-districts(towns).Adult residents aged greater than 18 were selected as investigation subjects,their dietary iodine intake in the past 24 hours was investigated,and the Food composition table” was inquired to get the data of dietary iodine intake.One hundred copies of residential edible salt samples and drinking water samples in each of the selected community (village) were collected to detect salt iodine and water iodine by direct titrimetric and spectrophotometric method,respectively.Results The mean of adult residents' dietary iodine intake in Zhejiang coastal area was 267.76 μg/d,which was less than that in inland area (429.05 μg/d,t =- 6.90,P ＜0.05),and the means of adult residents' dietary iodine intake from drinking water,laver and fish(5.75,69.72,5.61 μg/d,respectively) in coastal area were higher than those in inland areas(3.25,35.27,3.43 μg/d,respectively,t =21.73,3.92,4.08,all P ＜ 0.05),however,the means of adult residents' dietary iodine intake from salt,kelp and other food (166.81,3.04,16.82 μg/d,respectively) in coastal areas were less than those in inland areas (355.15,6.14,25.81 μg/d,respectively,t =- 8.76,- 5.49,- 18.56,all P ＜ 0.05).In coastal areas,the proportion which was less than estimated average requirement of iodine(EAR,120 μg/d) was 46.48％ (1029/2214),the ratio which was higher than the maximum tolerable intake of iodine(UL,1000 μg/d) was 3.34％ (74/2214),and the average contribution rate of dietary intake of iodine in salt was 62.30％(166.81/267.76).While in inland areas,the corresponding proportions were 7.61％ (171/2246),2.80％ (63/2246) and 82.78％ (355.15/429.05),respectively.Conclusions The dietary iodine intake in Zhejiang inland areas has reached the recommended nutrient intake levels of the Chinese Nutrition Society,but there is a certain degree of insufficient iodine intake in population of the coastal areas.

OBJECTIVETo investigate the nutritional status of school-age children in rural area in Hunan, China from 2012 to 2015 and to evaluate the effectiveness of the "Nutrition Improvement Program for Compulsory Education Students in Rural Area" (hereinafter referred to as "Nutrition Improvement Program").

METHODSThe nutritional status of school-age children aged 6-14 years was evaluated after the implementation of the "Nutrition Improvement Program" and the changing trend of the children's nutritional status was analyzed. The statistical analysis was performed on the monitoring data of the school-age children aged 6-14 years in rural area in Hunan, China from 2012 to 2015, which came from "The Nutrition and Health Status Monitoring and Evaluation System of Nutrition Improvement Program for Compulsory Education Students in Rural Area".

RESULTSIn 2015, female students aged 6-7 years in rural area in Hunan, China had a significantly greater body length than the rural average in China (P<0.05). However, the other age groups had significantly smaller body length and weight than the rural averages in China (P<0.05). After the implementation of "Nutrition Improvement Program", the prevalence rate of growth retardation decreased (P<0.05), but the prevalence rate of emaciation increased (P<0.05). At the same time, the prevalence rate of overweight/obesity increased (P<0.05) and the prevalence rate of anemia decreased (P<0.05).

CONCLUSIONSThe implementation of "Nutrition Improvement Program" has achieved some success, but the nutritional status of school-age children has not improved significantly. Overweight/obesity and malnutrition are still present. Therefore, to promote the nutritional status of school-age children it is recommended to improve the measures for the "Nutrition Improvement Program".

Objective To learn the status of iodine nutrition and the goiter of children and pregnant woman in Zhejiang Province after the iodine salt concentration adjustment.Methods The proportionate to population size sampling was applied to select 30 surveillance areas in Zhejiang Province,and iodine nutritional status were evaluated by 4 indicators that include goiter rate in 8 -10 years old children,urine iodine,iodized salt and water iodine.Results The iodine content of 1 565 edible salt samples collected from the above children was measured,and the iodine median(P25 -P75 )was 23.30 (21.00 -25.80)mg/kg.The coverage of iodized salt rate was 88.43%,and 95.88% iodized salts was qualified.The qualified iodized -salt ingesting rate was 84.79%.The iodine content of children aged 8 -10 years old and pregnant woman was tested,and iodine median (P25 -P75 )was 171.99 (113.00 -243.89 ),134.14 (82.10 -202.98)g/L respectively.The iodine content of 66 water samples were randomly collected from the surveillance areas to be tested,and iodine median(P25 -P75 )was 2.42(1.17 -6.28)μg/L.The proportion less than 10 g/L was 87.9%.The goiter status of 1 565 children were examined by B -type of ultrasonic,and the prevalence of goiter was 4.98%.Conclusion After the iodine salt concentration adjustment,the status of iodine nutrition in children was in optimum level,but the level of iodine nutrition in pregnant women was less than the state,which should be paid more attention.

OBJECTIVEOsteopetrosis is a rare genetic disorder and the malignant infantile osteopetrosis (MIOP) is the worst subtype of this disease. Seventy percent of patients die in six years of life without proper treatment. Hematopoietic stem cell transplantation (HSCT) offers the only chance of cure for MIOP.

METHODRetrospective analysis was performed on 8 patients with MIOP who underwent HSCT in Beijing Children's Hospital during the period from 2006 to 2011.

RESULTEight cases (4 male and 4 female, mean age at HSCT 13.5 months) were diagnosed as malignant infantile osteopetrosis. Conditioning regimen included fludarabine, busulfan and cyclophosphamide. All patients received cyclosporin for prophylaxis of graft vs. host disease (GvHD). A UMD recipient underwent CD34(+) cell selection. ATG/ALG, mycophenolate mofetil (MMF) and methotrexate (MTX) used for recipients with unrelated cord donor (2) and recipients with haplo-identical donors (5). Average time for neutrophil engraftment was 15.7 day (9 - 36), platelet engraftment was 43.3 day (10 - 68). The patients were followed up from 47 days to 5 years, 1 patient died of post-transplant complications. Seven cases presented better in clinical manifestation. Acute GvHD I°-II° was observed in 6 patients, III°-IV° in 2 patients. It was controlled by anti-GvHD therapy.

CONCLUSIONNon-allogenic stem cell transplantation treatment of infantile MIOP showed high survival rate and restoration of hematopoiesis in haploid transplant patients, therefore, non-allogenic HSCT may be an option to treat MIOP in children.

Objective The role of BMI1 gene in the development of gastrointestinal stromal tumor (GIST) has not yet been clarified. This study aimed to explore the expression of BMI1 gene in gastrointestinal stromal tumor,and analyze its relationship with clinical pathological features of GIST. Methods The clinical data of 68 GIST patients treated in The First People's Hospital of Nan-ning from August 2012 to October 2015 were analyzed retrospectively. The expression of BMI1 in normal gastrointestinal tissues and GIST tissues were detected with immunohistochemistry method,and analyzed the relationship between various clinicopathological pa-rameters of GIST and BMI1. The expression of BMI1 protein was detected by Western blot. Results The positive rate of BMI1 was much higher in GIST group than in non-GIST (76.47% vs 36.84%,P<0.05). The difference in the expression of BMI1 protein between the different risk groups was statistically significant (P<0.05). The positive expression rate was the highest in the high-risk group (93.75%),but had no statistically significant difference among different genders,age,locations,histological types and whether me-tastasis (P>0.05). Expression of proliferation genes such as PCNA,CyclinD1 mRNA in BMI1 positive group were higher than those in BMI1 negative group,the expression of Pro-apoptotic genes such as Caspase-7,Smac mRNA were lower than those in BMI1 negative group,the expression of anti-apoptosis genes such as Livin,p53,Bcl-2 mRNA were higher than those in BMI1 negative group (P<0.05). Conclusion The expression of BMI1 protein was increased in GIST tissue. It is correlated with the risk classification,and is an important factor affecting the prognosis of patients.

The aim of the study is to evaluate the effects of the single and mixed decoction of Thallus laminariae (kelp) and Glycyrrhiza glabra (licorice) on the metabolism and their difference. The mixed decoction of kelp and licorice and the single decoction were made and intragastrically administered to the SD rats. The effect on system metabolism, the toxicity of liver and kidney were assessed by GC-MS profiling of the endogenous molecules in serum, routine biochemical assays and histographic inspection of tissues from SD rats, separately. The mixed decoction of kelp and licorice induced more obvious pathological abnormalities in SD rats than a single decoction of kelp, while the extracts of licorice did not show any pathological change. Neither the mixed, nor the single decoction showed abnormal histopathology. After intragastric administration of extracts for 5 days, the mixed decoction induced a decrease of ALT (no significant change in the groups of single decoction) and an increase of BUN (so did the single decoction of kelp). Metabolomic profile of the molecules in serum revealed that the metabolic patterns were all obviously affected for the three groups, i.e., the mixed and single decoction of kelp and licorice. The rats given with the single decoction of kelp showed a similar pattern to that of the mixed decoction, indicating that the kelp primarily contributed the perturbation of metabolism for the mixed decoction. All three groups induced a decrease of branched chain amino acids, TCA cycle intermediates and glycolysis intermediates (e.g., pyruvic acid and lactic acid) and an increase of 3-hydroxybutyric acid. Kelp decoction showed stronger potential in reducing TCA cycle intermediates and glycolysis intermediates than the other two groups, while the levels of branched chain amino acids were the lowest after licorice extracts were given. These results suggested that the effect of the mixed decoction on metabolism was closely associated with both kelp and licorice. The continuous administration of single decoction of kelp and the mixed decoction of licorice and kelp resulted in pathological abnormalities in kidney of SD rats. The mixed decoction of kelp and licorice distinctly perturbed sera molecules and hence system metabolism, which showed associated with those of kelp and licorice. Although the metabolic effect was associated with both kelp and licorice, the results suggested kelp contributed to it primarily.

Objective To analyze the epidemic tendency of Microtus fascus plague during 2000-2008 in Sichuan province. Methods To investigate the plague each year according to "overall Plan of the Plague in the Whole Nation" and "Surveillance Program of Sichuan Province Plague". Results There were plague epidemic from 2000 to 2008, with the average density as 312.41/ha. 42.57% of the Microtus fuscus were infected by body Fleas. The Fleas Index was 0.88 and the Index for nest Fleas of Microtas fuscus was 55.89. Six kinds of animals were infected by not only the Microtus fuscus but also herd-dog, sand fox, Tibetan sheep, domestic cats and Cricetulus longicaulatus as well. The positive rate of live Microtus fuscus was 0.32% but 22.99% in the dead Microtus fuscus. The overall positive rate on serological test was 6.70%. There were 4 Sections, 11 species and 19 kinds Fleas identified and carrying 3 kinds of fleas, Callopsylla sparsilis, Amphipsylla tntua tutua and Rhadinopsylla dahurica vicina, with the overall infection rate as 0.054%. Conclusion Plague among Microtus fuscus showed a continuous epidemic in Sichuan province during 2000-2008.

Objective To analyzed the variant information on the indices regarding fleas from natural foci of Microtus plague in Sichuan epidemic area during 2000 to 2008.Methods Statistical and analytical methods were used on the surveillance data regarding Microtus fuscus plague.Results There were 19 flea species identified and the share of Callopsylla sparsilis was 62.79 percent while the share of Amphipsylla tuta tuta was 30.90 percent on Microtus fuscus plague.The infection rate of fleas and the flea index were the highest in October and the lowest in December and March.Species as Callopsylla sparsilis,Amphipsylla tuta tuta and Rhadinopsylla dahurica vicina could naturally infect the Yersinia pestis.Conclusion Microtus fuscus plague could become epidemic when animals and flea species were infected.We should emphasis on plague monitoring program so as to prevent the occurrence of the disease.
