Chinese medicine has developed rapidly in the world, but the international standard system has not been established, further affecting the healthy development of Chinese medicine. Technical status of the member states are closely related to the current legislation and regulations in the development of Chinese medicine, which is important for developing international standards for TCM strategies. By the findings of ISO Technical Committee of Traditional Chinese Medicine (ISO/TC249) 7 European P member (Participating countries) International Traditional/Alternative Medicine (TM/CAM) legislative status, herbal medicine in each member country has a large market, a good environment for the development of some countries. After“The EU Traditional Herbal Medicinal Products Directive 2004/24/EC”issued by the member states for the registration and management in European, regulation of herbal products become more stringent. There are relatively small quantity of TM/CAM practitioners, lack of education for practitioners and standardized management.

Objective To evaluate the clinical impact of 18F-FDG PET/CT on patients with suspected cervical cancer recurrence. Methods Fifty-one cervical cancer patients, clinically suspected to have tumor recurrence during follow-up, underwent 18F-FDG PET/CT examination. 18 F-FDG PET/CT results were compared with those of conventional images, as referred to histopathology or clinical follow-up. Impacts of 18F-FDG PET/CT were evaluated based on documented changes of clinical management. Results In total, 43 patients were found to have positive lesions by 18F-FDG PET/CT, in which 40 were true recurrence,but 2 were pelvic abscess and 1 was radiation enterocolitis. Other 8 patients were found negative by 18F-FDG PET/CT and confirmed by pathology or follow-up. In patient-based analyses, the sensitivity, specificity, and accuracy of 18F-FDG PET/CT for the detection of tumor recurrence were 100% (40/40), 72. 73% (8/11),and 94.12% (48/51) respectively. In 7 patients, the clinical management was changed due to 18F-FDG PET/CT findings. Conclusion 18F-FDG PET/CT is an efficient tool for determining the recurrence of cervical cancer and instructing the clinical management.

Objective To investigate the effects of zinc deficiency on the expressions of Th1/Th2 cytokine interferon-?(IFN-?) and interleukin-4(IL-4)in asthmatic rats.Methods Animal models of asthma and zinc deficiency were established.Thirty-two SD rats were divided into 4 groups according to weight:zinc deficient diet with ovalbumin(OVA) challenge group(group A),zinc normal diet with OVA challenge group(group B),zinc normal pair-fed diet with OVA challenge group(group C) and zinc normal diet with saline challenge group(group D).The contents of IFN-? and IL-4 in lung homogenate were detected by enzyme linked immunosorbent assay(ELISA).The levels of IFN-? and IL-4 mRNAs were observed by reverse transcriptase-polymerase chain reaction(RT-PCR).Results Compared with group D,the content and mRNA expression of IFN-? of lung in group A,group B and group C all decreased significantly(all P0.05).No marked difference was found between group B and group C in all the results.Conclusions Zinc deficiency reduces the expression of IFN-? but have no influence on IL-4.The imbalance of Th1/Th2 cytokine may be associated with the increasing airway inflammatory reaction in zinc deficient asthmatic rats.

ObjectiveTo explore the association between angiotensin converting enzyme (ACE) gene insertion/deletion(I/D) polymorphism and cerebral infarction among Chinese people. MethodsThe ACE gene polymorphism was determined by PCR-RFLP in 242 patients with cerebral infarction and 283 controls. Multiple logistic regression was performed to explore the risk factors for cerebral infarction. ResultsAfter adjusting age, gender, alcohol drinking, smoking, education,history of diabetes mellitus and the primary hypertension, there was no significant association between ACE I/D polymorphism and cerebral infarction, either was hypertension and diabetes mellitus. The primary hypertension significanlly increased risk of cerebral infarction (OR=7.28,P =0.000). Both ACE ID/DD genotype and the primary hypertension showed a significant gene-environment interaction(r=1.62,OR=7.29), something as super multiplicative type 2 interaction. ConclusionAlthough ACE gene polymorphism is not risk factors of cerebral infarction, but ID/DD genotype had shown significant gene-environment interaction with primary hypertension in occurrence of cerebral infarcion.

Abstract: Objective To analyze the effect of nutrition package on the nutritional status and prevalence of children in rural areas of Hainan Province, and provide scientific basis and suggestions for further improving the nutritional and health status of children in this region. Methods　Four cities and counties were randomly selected as the intervention group, and four cities and counties matched with the intervention group in terms of population, economy, social culture, maternal and child health work foundation of township health centers, physical nutrition and health status were selected as the control group.With the combination of monitoring and prospective cohort study, infants in the intervention group and the control group were studied from June 1, 2020, and they were intervened for 12 months with supplementary food nutrition package. Before and after intervention, the nutrition and health status of infants aged 6-24 months in the intervention group and the control group were investigated to evaluate the nutritional and health effects of supplementary food nutrition package for infants aged 6-24 months in rural Hainan Province. Results　A total of 999 infants were investigated, including 427 in the intervention group and 572 in the control group. After 12 months of nutritional intervention, there was no significant difference in weight-for-age Z-score (WAZ) and height-for-age Z-score (HAZ) and weight-for-height Z-score (WHZ) between the intervention group and the control group (P>0.05). The rate of emaciation of the intervention group was 1.64%, which was significantly lower than 3.67% of the control group (P<0.05). There were no significant differences in the rate of growth retardation (2.81% and 3.32%, respectively) and underweight (0.47% and 1.92%, respectively) between the intervention group and the control group (P>0.05). The rate of respiratory infection and diarrhea in the intervention group were 9.13% and 1.17%, which were significantly lower than corresponding 23.25% and 3.15% in the control group (P<0.05). The hemoglobin of the intervention group and the control group were 117.24 g/L and 114.51 g/L respectively, and the rates of anemia were 11.11% and 22.84% respectively, the differences were statistically significant (P<0.05). Conclusions　The intervention of nutrition package in rural areas of Hainan Province has achieved the expected results, and supplementary food nutrition package has reduced the incidence of malnutrition and respiratory infection and diarrhea in recent two weeks in infants and anemia to a certain extent. We should attach great importance to the supplementary nutrition package for right-age children and promote the growth and health of children in rural areas through supplementary nutrition package, and continuously improve the nutrition and health level of children in Hainan Province.

Objective Take alkaline ashing method as golden standard to explore the accuracy of chloric acid digestion method in determination of human milk iodine. Methods Sixty one breast milk samples collected in Hexi district of Tianjin was measured by the method for determination of iodine in foodstuff by As3+-Ce4+ catalytic spectrophotometry (referred to as the alkaline ashing method) published in 2008 and the method for determination of iodine in urine by As3+-Ce4+ catalytic spectrophotometry(referred to as acid digestion) published in 1999, respectively. were highly correlated(r = 0.960, t = 26.3, P < 0.01), and the regression equation was (Y) = - 28.1 + 0.808X, in which X was independent variable, that is the results of alkaline ashing method; (Y) was dependent variable, that is the estimated data of chloric acid digestion method. The average difference of the results measured by the two methods was 68.3 μg/L, and the results from chloric acid digestion was 38.9% which lower than that of alkaline samples were diluted by 3,4 and 5-fold and then digested by chloric acid, the liquid clarification rates were 80.3% ashing and chloric acid digestion method were, respectively, 165.4, 110.0 μg/L. Conclusions Compared with alkaline ashing method, the results determined by chloric acid digestion method are significantly lower. It is suggested that there are systemic errors in chloric acid digestion method, which means that alkaline ashing method can not be replaced by the chloric acid digestion method.

OBJECTIVETo explore clinical and laboratory factors associated aspirin response, and the association between gastrointestinal bleeding and aspirin response in aged patients.

METHODSA total of 136 patients aged 60 and over [mean age (74.9 ± 7.0) years] with ischemic heart disease and at high risk for ischemic heart disease were included. Arachidonic acid induced platelet aggregation (AA-Ag) was measured before and at 7(th) day after taking aspirin (100 mg/d). Patients were followed for 6 months and incidence of gastrointestinal bleeding was obtained.

RESULTSPost-treatment AA-Ag was significantly reduced compared to baseline (13.29% ± 5.52% vs. 73.20% ± 7.32%, P < 0.05). A heterogeneous distributed post-treatment AA-Ag was observed (range 0.42% to 30.50%). Post-treatment AA-Ag was positively correlated with baseline AA-Ag (r = 0.493, P < 0.01). The level of post-treatment AA-Ag was significantly higher in the fourth quartile group at baseline than in the others quartile groups at baseline. Patients aged 80 years and over had significantly lower post-treatment AA-Ag (10.25% ± 4.68%) compared with patients of 60 - 69 years (13.96% ± 5.20%) and of 70 - 79 years (13.73% ± 5.48%, all P < 0.01). The incidence of patients in the lowest quartile of post-treatment AA-Ag was significantly higher in patients ≥ 80 years (38.24%) than in patients of 60 - 69 years (11.1%) and of 70 - 79 years (24.0%). Multiple variable analysis revealed post-treatment AA-Ag was significantly influenced by baseline AA-Ag, ≥ 80 years old, diabetes mellitus and acute coronary syndrome. We observed 4 (2.9%) mild gastrointestinal bleeding during follow up. Post-treatment AA-Ag was in the lowest quartile in 3 patients with mild gastrointestinal bleeding.

CONCLUSIONSIncreased baseline platelet reactivity as well as diabetes mellitus and acute coronary syndrome are associated with low aspirin response in the aged patients. Aspirin response is significantly higher in very old patients.

OBJECTIVETo investigate the changes of gene expression file in transitional cell carcinoma of bladder after hepatocyte cell adhesion molecule(hepaCAM) overexpression.

METHODSAffymetrix Human Genome U133 Plus 2.0 Array was used to investigate the changes of gene expression profile between adenovirus-green fluorescent protein(GFP) -hepaCAM group and GFP group in transitional cell carcinoma of bladder EJ cells.Significant Analysis of Microarray(SAM) was used to screen the differentially expressed genes, DAVID software was used to conduct gene ontology analysis and wikiPathway analysis based on the differentially expressed genes. Reverse transcription-polymerase chain reaction and Western blot were applied to verify microarray data.

RESULTSCompared with the GFP group, a total of 2469 genes were up-regulated or down-regulated by more than 2 times in the GFP-hepaCAM group. Among these genes, 1602 genes were up-regulated and 867 were down-regulated.Most of the differentially expressed genes were involved in the function of cell proliferation and cell cycle regulation. The mRNA expressions of nibrin, liver kinase B1, and cyclin D1 detected by reverse transcription-polymerase chain reaction in three different bladder cancer cell lines were consistent with the microarray data.The protein expressions of nibrin and liver kinase B1 in these three cell lines measured by Western blot were consistent with the mRNA expression.

CONCLUSIONSHepaCAM can alter the gene expression profile of bladder cancer EJ cells. The well-known anti-tumor effect of hepaCAM may be mediated by regulating the gene expression via multiple pathways.

OBJECTIVETo compare the incidence of emotional disorder in patients with acute or stable coronary heart disease.

METHODSA total of 298 patients with suspected coronary heart disease (CHD) were designed into three groups based on of coronary angiography results: acute coronary syndrome (ACS, n = 128), stable angina pectoris (SAP, n = 108) and non-CHD (n = 62). All patients were evaluated by Zung Self-rating Depression Scale (SDS), Zung Self-rating Anxiety Scale(SAS) and Hamilton Depression Rating Scale (HRSD) for depression and anxiety before coronary angiography (CAG), 3 days after CAG, and 1 day before discharge.

RESULTSIncidences of depression and anxiety were significantly higher the ACS group (65.6%and 78.9% before CAG; 60.9% and 70.3% 3 days post CAG; 45.3%and 64.8% before discharge) compared patients with SAP (18.5% and 26.9% before CAG; 17.6% and 28.7% 3 days post CAG; 15.7% and 26.9% before discharge, all P < 0.05 vs. ACS) and non-CHD patients (32.3% and 25.8% before CAG; 27.4% and 24.2% 3 days post CAG; 29.0% and 30.6% before discharge, all P < 0.05 vs. ACS) while the depression and anxiety incidences were similar between patients with SAP and non-CHD in this cohort (P > 0.05).

CONCLUSIONEmotional disorder is common in patients with suspected heart diseases, especially in patients with ACS. Psychological distress of patients with suspected heart disease should be evaluated and treated.
