Objective:To explore the relationship between vegetarian diets and vitamin B 12 levels in Chinese pregnant women. Methods:A cross-sectional survey was used to explore the relationship between vegetarian diets and vitamin B 12 levels in Chinese pregnant women based on data from the Chinese National Nutrition and Health Surveillance (2015-2017). Maternal serum vitamin B 12 concentration was determined by electrochemiluminescence. Background and diet information of all subjects were collected using general and food frequency questionnaires. General Linear Model was used to analyze the difference in serum vitamin B 12 levels between vegetarian and non-vegetarian pregnant women and multivariate logistic regression for examining the relationship between vegetarian diets and vitamin B 12 deficiency (vitamin B 12<150 pmol/L) in pregnant women. Results:A total of 8 366 pregnant women were included in the analysis, and vegetarians accounted for 1.2% (102/8 366). The median serum vitamin B 12 concentrations were 155.8(93.6-212.4) pmol/L and 187.2(127.4-267.6) pmol/L ( Z=－4.22, P<0.001), and the vitamin B 12 deficiency rates were 48.0% (49/102) and 35.0% (2 896/8 264) in vegetarian and non-vegetarian women, respectively. The vitamin B 12 deficiency rate in vegetarian women was 0.89-fold higher than in non-vegetarians (95% CI: 1.24-2.89). Among the vegetarian and non-vegetarian pregnant women, vitamin B 12 deficiency rates during the first, second, and third trimesters were 34.8%(16/46), 54.3%(19/35), 66.7%(14/21), and 20.4%(521/2 559), 32.6%(941/2 886), 50.9%(1 430/2 807), noting for an increasing trend ( Z=23.54 and 2.57, P=0.010 and P<0.001). Conclusions:Vegetarian pregnant women are at high risk of vitamin B 12 deficiency. Compared with non-vegetarian women, vegetarian pregnant women in China have lower vitamin B 12 levels and a higher risk of vitamin B 12 deficiency. Moreover, the risk of vitamin B 12 deficiency will gradually increase during pregnancy.

Objective:To observe the clinical effect of scraping therapy on lumbar disc herniation (LDH) with different syndromes.Methods:Using the convenient sampling method, a total of 30 non-emergency LDH patients who were admitted to Department of Orthopedics and Traumatology of Yangzhou Hospital of Traditional Chinese Medicine from July 2017 to June 2018 were selected as the research objects. Among them, there were 11 cases of qi stagnation and blood stasis syndrome, 8 cases of damp-heat obstruction syndrome, 7 cases of cold-damp obstruction syndrome and 4 cases of liver and kidney deficiency syndrome. Du meridian, the bladder meridian of Foot Taiyang, as well as Jiaji (EX-B2) in pathological or painful sections, Ashi point, Shenshu (BL 23) , and Weizhong (BL 40) were mainly scraped. The treatment interval is 2~5 days (the marks of scrapping fade) , twice of scrapping as a treatment course and a total of 3 courses involved in the whole treatment. Japanese Orthopaedic Association (JOA) Score, Visual Analogue Scale (VAS) , serum interleukin-1 β (IL-1β) and interleukin-10 (IL-10) were compared before and after scraping.Results:Compared with those before scraping, the JOA score increased, the VAS decreased, the serum IL-1β content decreased and the serum IL-10 content increased after scraping, and the differences were sttaistically significant ( P<0.01) . Among them, the JOA scores of patients with qi stagnation and blood stasis syndrome and cold-damp obstruction syndrome were higher than those of damp-heat obstruction syndrome and liver-kidney deficiency syndrome, and the differences were statistically significant ( P<0.05) . The levels of serum IL-10 in patients with qi stagnation and blood stasis syndrome, damp-heat obstruction syndrome and cold-damp obstruction syndrome were higher than those in patients with liver-kidney deficiency syndrome, and the differences were statistically significant ( P<0.05) . Conclusions:The curative effect of scraping in the treatment of LDH is definite, and the curative effect is better for excessive syndromes.

OBJECTIVE：To develop a metho d for determining the plasma concentration of sulfasalazine （SSZ）metabolite sulfapyridine（SP）in rats ，and to investigate the effects of esomeprazole （ESOM）on the pharmacokinetic behavior of SSZ in rats. METHODS：Male SD rats were randomly divided into SSZ group and SSZ+ESOM group ，with 6 rats in each group. SSZ+ESOM group were given Esomeprazole enteric-coated tablets [ 90 mg/（kg·d）] intragastrically for 14 days. On the 15th day ，the rats in 2 groups were given Sulfasalazine enteric coated tablets （90 mg/kg）intragastrically，and blood sample was collected from the inner canthus at 0.5，1，1.5，2，3，4，6，8，10，12，24，36，48，72 h after administration. After protein precipitation with methanol ， using diazepam as internal standard ，Agilent XDR-C 18 column was adopted with methanol- 0.1％ formic acid solution （gradient elution）as mobile phase. The concentration of SSZ metabolite SP in plasma was determined by LC-MS/MS. The pharmacokinetic parameters were calculated by using DAS 3.0.1 software and compared between 2 groups. RESULTS ：The linear range of SP were 2-1 000 ng/mL. The methodology met the requirements of Chinese Pharmacopeia . There was no statistical significance in pharmacokinetic parameters of SP between 2 groups，such as AUC 0－t，tmax，t1/2z，cmax，MRT0－t（P＞0.05）. CONCLUSIONS ：The established method is simple ，rapid and sensitive ；it can be used for the concentration determination of SSZ metabolite SP in plasma. ESOM has no significant effect on the pharmacokinetic behavior of SSZ in rats.

The existing researches on scraping mostly focus on the observation of curative effect and preliminary attempts to explore the mechanism of action, but the research on scraping manifestation is slightly insufficient. At present, scraping manifestation studies mainly include skin appearance, skin blood perfusion, and skin temperature. These studies have laid the foundation and provided a reference for the standardization, normalization, and visualization research of scraping technology in the future. However, these studies are still in their infancy and need to be further studied.

Objective To investigate the relationship between pulmonary arterial ( PA) enlargement and pulmonary function in patients with chronic obstructive pulmonary disease (COPD).Methods From December 2012 to June 2016,78 patients with acute exacerbation of COPD in the Eighth People＇s Hospital of Qingdao were selected. According to pulmonary CT findings,they were divided into two groups : PA enlargement group (38 cases) was PA＞3.0cm,normal PA group(40 cases) was PA≤3.0cm.FEV1and FVC of stable phase were compared.Results The FEV1of men in the A enlargement group was (1.08 ±0.44)L,that in the normal PA group was (1.44 ±0.66)L,the difference was statistically significant (t＝2.27,P＝0.028).The FEV1of women in the PA enlargement group was (0.90 ±0.41)L,which in the normal PA group was (1.35 ±0.58)L,the difference was statistically significant (t＝2.28,P＝0.026).Correlation analysis showed that the diameter of PA was negatively related with FEV 1/FVC(r＝-0.509,P＝0.001),PA enlargement was related with lung function decline.Conclusion COPD patients with PA enlargement are more associated with accelerated loss of lung function and should be treated early.

Objective To investigate the mechanism of Qinggan-Huoxue recipe in the treatment of alcoholic liver disease by observing its function on alcoholic liver disease rat fibroblast growth factor -21 (FGF21). Methods The rats were randomly divided into the blank group (n=10), the carbon tetrachloride group (n=10), the model group (n=11), the Qinggan-Huoxue recipe group (n=10), the Qinggan recipe group (n=9) and the Huoxue recipe group (n=10). Except for the blank group and the carbon tetrachloride group, the other rats were given 10 ml/kg alcohol, corn oil and pyrazole mixture (4.5 ml: 2 ml: 25 mg), once a day, 0.3 ml/kg carbon tetrachloride olive oil solution (carbon tetrachloride: olive oil =1: 3) intraperitoneally, and twice a week for 12 weeks to prepare the alcoholic liver disease model. In the ninth week, the Qinggan-Huoxue recipe group was treated with 4.75 g/kg of Qinggan-Huoxue recipe, the Qinggan recipe group was treated with 1.5 g/kg of Qinggan recipe, and the Huoxue recipe group was treated with 3.25 g/kg of Huoxue recipe, once a day, and 28 d for continuous administration. The pathological changes of liver tissue were observed by HE staining and Masson staining. The serum levels of AST and ALT were detected in rats. The changes of FGF21 protein and mRNA expression were detected by immunohistochemistry, Western blotting and fluorescence quantitative PCR. Results Compared with the model group, the liver weight and liver body ratio in the Qinggan recipe group, Qinggan-Huoxue recipe group and Huoxue recipe group were significantly lower (P<0.01). Compared with the model group, the serum ALT (41.95 ± 26.78 U/L, 46.63 ± 21.00 U/L, 37.57 ± 27.85 U/L vs. 138.34 ± 43.35 U/L), AST (102.74 ± 23.55 U/L, 111.50 ± 21.26 U/L, 83.72 ± 37.57 U/L vs. 257.41 ± 162.31 U/L) in the Qinggan recipe group, Qinggan-Huoxue recipe group and Huoxue recipe group significantly decreased (P<0.01 or P<0.05). Compared with the model group, the expression of FGF21 protein (1.19 ± 0.07, 1.24 ± 0.12 vs. 0.92 ± 0.04) in Qinggan recipe group and Qinggan-Huoxue recipe group significantly increased (P<0.05), and the expression of FGF21 mRNA (1.25 ± 0.08 vs. 0.95 ± 0.05) in Qinggan-Huoxue recipe group significantly increased (P<0.05). Conclusions FGF21 plays an important role in the alcoholic liver disease. During the process of liver injury, FGF21 increases continuously. Qinggan-Huoxue recipe can improve the content of FGF21 in the treatment of alcoholic liver disease.

OBJECTIVETo analyze a fetus with abnormal cardiac ultrasound by using various techniques and explore its genotype-phenotype correlation.

METHODSLymphocytes derived from umbilical cord blood sample were subjected to G-banding analysis. Short tandem repeats quantitative fluorescence PCR (STR-QF-PCR) was used for analysis of fetal DNA as an auxiliary test. Low-coverage whole genome sequencing (WGS) was used to detect chromosomal deletion/duplication which exceeded 100 kb in size.

RESULTSThe karyotype of the fetus was 47,XN,+mar. As detected by STR-QF-PCR, the copy number of GATA178F11 locus on chromosome 18 was 4, and the duplicated fragment was derived from the mother. WGS suggested that the fetus to be 46,XN,dup(18p11.21p11.32).seq [GRCh37/hg19](10 001-15 378 887)× 4, with the duplicated fragment spanning approximately 15.38 Mb.

CONCLUSIONThe cardiac malformation of the fetus may be attributed to the partial duplication of chromosome 18p. Combined cytogenetic and molecular methods can facilitate prenatal detection of genetic abnormalities.

Objective To explore the effects of family function on depression, activities of daily living, happiness index and quality of life among elderly hypertension patients. Methods From October 2015 to October 2017, we selected 80 elderly hypertension patients of Cardiovascular Department in the First Affiliated Hospital of Xinjiang Medical University by convenient sampling. All of the patients were divided into group of good family function and group of family dysfunction according to the Family Adaptation, Partnership, Growth, Affection and Resolve (APGAR). The scores were compared with the Self-Rating Depression Scale (SDS), Activities of Daily Living (ADL), Index of Well-Being Scale and 36-item Short form Health Survey (SF-36). SPSS 21.0 was used to statistical analysis. Results There were 47 (58.75%) patients in group of good family function and 33 (41.25%) patients in group of family dysfunction. The adaptation, intimacy, affection, growth and partnership of patients in group of good family function and the total score were superior to those in group of family dysfunction with statistical differences (P＜ 0.01). The scores of SDS and ADL of patients in group of good family function were lower than those in group of family dysfunction; the happiness index of group of good family function was higher than that of group of family dysfunction with a statistical difference (P＜0.01). The dimension scores of life quality of patients in group of good family function were higher than those of group of family dysfunction with statistical differences (P＜0.01). Conclusions We should pay attention to the family function of elderly hypertension patients, improve patients' happiness index, depression and ADL, so as to promote rehabilitation of hypertension patients.
