OBJECTIVETo determine whether lactic acid bacteria as probiotics is efficacious in the primary prevention of infantile eczema or atopic eczema.

METHODSFor this meta analysis of randomized controlled trials (RCT) describing the efficacy of probiotics in infants with eczema or atopic eczema at ages of ≤2 years, a comprehensive search in the databases was performed up to January 2010. Three reviewers independently evaluated the studies for methodological qualities. RevMan 5.0.2 software was used for meta analysis.

RESULTSTwelve RCTs on the preventive effects of lactic acid bacteria as probiotics on infantile eczema were included, and 7 of the 12 RCTs reported the preventive effect of lactic acid bacteria on atopic eczema. The meta analysis showed that there was an overall significant reduction in infantile eczema and atopic eczema favoring lactic acid bacteria compared with placebo. The relative risk (RR) ratios for eczema and atopic eczema were 0.80 (95%CI: 0.70-0.90; P<0.01) and 0.78 (95%CI: 0.64-0.97; P<0.01), respectively. Lactic acid bacteria combined with other probiotics decreased significantly the incidence of eczema, with a RR ratio of 0.79 (95%CI: 0.68-0.93; P<0.01). The use of lactic acid bacteria alone did not result in a reduction in the incidence of eczema, with a RR ratio of 0.85 (95%CI: 0.69-1.05; P>0.05).

CONCLUSIONSThe data from this meta analysis suggest that lactic acid probiotics combined with other probiotics play a role in the prevention of infantile eczema. There is insufficient evidence to recommend single use of lactic acid bacteria for prevention of eczema. Further studies are required to determine whether the findings are reproducible.

Objective To study the predictive effect of model ［GM(1,1)］ in China’s maternal and child health indicators, and to predict the future maternal and child health indicators in a short-term, and provide a scientific basis for the gradual improvement of maternal and child health care services in China. Methods The maternal mortality rate (MMR), neonatal mortality rate (NMR), infant mortality rate (IMR) and under-five mortality rate (U5MR) were collected from 2008 to 2017 in China. Models were established and MATLAB 2018b software was used for predictive analysis. Results The prediction models of maternal mortality rate, neonatal mortality rate, infant mortality rate and under-five mortality rate were as follows: x^(k+1)=-476.08e-0.09k+510.28(C1=0.165,P1=1.000)，x^(k+1)=-108.43e-0.09k+118.63(C2=0.043,P2=1.000)，x^(k+1)=-160.60e-0.09k+175.50(C3=0.085,P3=1.000),x^(k+1)=-224.37e-0.08k+242.87(C4=0.124,P4= 1.000)，the average relative errors were as follows: 3.46%,0.67%,1.75% and 2.36%。 Conclusions The GM (1,1) is suitable for the prediction of maternal and child health indicators in China, and the fitting accuracy is high. It is predicted that the indicators will continue to decline year by year in the next three years, and relevant departments should strengthen the management work in a targeted manner.

OBJECTIVETo describe the distribution changes of the mortality rate for cervical cancer in China between the 1970's and 1990's and provide the scientific evidence for the prevention and control strategies for cervical cancer campaign in China between next century.

METHODSData from two National Surveys for the Causes of Death in 1970's and 1990's in China. The crude and adjusted mortality rates for the cervical cancer and the distributions based on age and area were calculated and described. The comparison of the differences of changes between two mortality rates periods and together with its trends were shown based on the age-standardized.

RESULTSDuring two decades, the mortality rate for cervical cancer was 10.7 per 100,000 in 1970's which declined to 3.89 per 100,000 in 1990's, and from the 3rd ranking among all female malignant tumors to the 6th in 1990's (decreased about 63.64%). But the declination was not evenly. There have still been some high-risk areas, most located in rural countries in the mid-west of China, with rates remain unchanged and even at the highest level in the world, such as Wudu in Gansu and Yangcheng in Shanxi. A big difference was showed between rural country and city, but in both of them, the mortality rates in 1990's were significantly much lower than in 1970's (P = 0.001) at each five-year age group. And in the city, there was a much sharper increased trend in young women in 1990's.

CONCLUSIONSThe mortality rate for cervical cancer campaign in China has been substantially declined during past twenty years, but it's still a major health problem for women, especially in rural China. The focus of the prevention and control for the cervical cancer in the next century should put on rural areas, especially in mid-west of China and young women in the city.

Objective To validate the four chronic kidney disease epidemiology collaboration (CKD-EPI) predictive equations based on serum creatinine (SCr) and cystatin C (Cys C) in Chinese CKD patients,and try to develop the GFR predictive equations for Chinese CKD patients.Methods254 CKD patients were randomly selected from four Grade ⅢA hospitals in different regions in China from September 2007 to December 2010.Clearance of dual plasma sampling 99mTc-DTPA was used to measure glomerular filtration rate (rGFR) in 254 CKD patients.The serum concentration of Cr and Cys C were measured.CKD-EPI SCr equation,Cys C equation,Cys C equation adjusted for age,sex and race,SCr/Cys C combinated equation adjusted for age,sex and race were used to estimate GRF ( labeled as eGFR1,eGFR2,eGFR3 and eGFR4,respectively).The correlation,bias and precision of eGFRs were compared with rGFR by Wilcoxon signed rank test,intraclass correlation coefficient (ICC) and Spearman correlation analysis.The deviation degree between rGFR and different eGFRs was compared via Bland-Altman graph.The accuracy within 15％,25％,30％ ( P15,P25,P30) and the staging correctness of eGFR against CKD at different stages was calculated.ResultsThe rGFR in 254 CKD participants was [ 48.07 (26.19 -92.97 )] ml · min -1·(1.73 m2) -1.The Spearman correlatiou coefficients (CC) of eGFR and rGFR varied within the range of 0.873 - 0.896 ( P =0.000 ).The intra-class CC ( ICC ) varied within the range of 0.920 - 0.942.The correlation of eGFR4 was the best.The absolute deviations of 4 eGFRs and deviation precision were eGFR4 ＜eGFR3 ＜ eGFR2 ＜ eGFR1.The 95％ confidence intervals for the regression line of 4 eGFRs shown by Bland-Altman graphs were 92.5,87.3,83.0 and 76.1 ml · min-1 · ( 1.73 m2 ) -1,respectively,with the best result of eGFR4.For P30,the correctness of 4 eGFRs were eGFR4 ＞ eGFR3 ＞ eGFR2 ＞ eGFR1,but no significant difference was found by Chi square test (x2 =6.448,P =0.092).The overall correctness rate in 4 eGFRs against CKD stages were 48.4％ -57.5％,with the highest consistency of eGFR4,but their staging correctnessratewerenotideal(Kappa values were 0.405,0.348,0.366 and 0.463,respectively).Conclusions Compared with CKD-EPI SCr equation,no advantage was found in CKD-EPI Cys C equation.The Cys C equation adjusted by age and sex shows a little advantages over CKD-EPI Cys C equation in bias,precision,correlation and accuracy.The CKD-EPI SCr/Cys C combinated equation adjusted by age,sex and race has advantage over other three equations not only in bias,precision,correlation and accuracy,but also in staging correctness.However,the validation of this equation is still not fairly ideal for Chinese CKD patients.Based on these findings,it is essential for the Chinese CKD patients to develop SCr/Cys C combined predictive equation which adjusted by age,sex or other factors.(Chin J Lab Med,2012,35:798-804)

OBJECTIVETo investigate the blood flow characteristics of hepatitis B cirrhosis based on Couinaud's hepatic segments and to analyze the correlation between perfusion parameters of liver cirrhosis in the hepatic segments and between the different Child-Pugh classifications by using the pattern of whole liver perfusion detected by multi-slice spiral computed tomography (MSCT).

METHODSWhole-liver perfusion enhanced CT imaging scan was performed for 51 patients with hepatitis B cirrhosis (including 24 classified as Child-Pugh A, 19 as Child-Pugh B, and 8 as Child-Pugh C) and 20 patients without any liver abnormalities (who served as the control group).The perfusion parameters of Couinaud's segments were measured in order to compare the blood perfusion differences among the Couinaud's hepatic segments in liver cirrhosis. The blood flow characteristics were analyzed for each lobe and compared between groups, and the time to peak and peak of enhancement values of the aorta and portal veins and spleen were recorded and compared between groups.The F-test was used for statistical analysis.

RESULTSThe liver cirrhosis group showed higher time to peak for aorta and portal veins and spleen but lower peak of enhancement values than the control group. The hepatic arterial perfusion (HAP) was significantly higher in segment 3 than in segment 7 were (11.40+/- 5.72 vs.9.46+/-5.18 mL/min/100 mL; P less than 0.05). In addition, the differences of the portal venous perfusion (PVP) and total hepatic perfusion (THP) were significant between the liver lobes in various groups (P less than 0.05). The HAP and hepatic perfusion index (HPI) were not significantly different between the groups, but the HAP and HPI in every lobe were higher in the Child C subgroup than in either the Child A or Child B subgroups.

CONCLUSIONThe cirrhotic liver has different blood flow in the various Couinaud's segments. Whole-liver perfusion MSCT can reflect the hemodynamic changes of liver cirrhosis and Child-Pugh classification, and as such may be helpful for distinguishing the normal liver from the cirrhotic liver.

OBJECTIVEThe purpose of this article is to examine the effect of curcumin on the proliferation and metastasis of human tongue squamous cell carcinoma and analyze its mechanism.

METHODSSCC-4 were treated with curcumin of 0, 5, 10, 20, 30, 60, 100 micromol x L(-1) in 24 h. MTT assay, Matrigel invasion assay, flow cytometry and fluorescence microscopy were used to examine the effect of curcumin on the growth and metastasis of SCC-4. cDNA microarray and RT-PCR were employed to analyze the expression of genes treated by curcumin.

RESULTSThe results showed that curcumin could concentration-dependently inhibit SCC-4 cell proliferation at the concentration range from 20 to 100 micromol x L(-1). Furthermore, Matrigel invasion assay indicated that curcumin can reduce SCC-4 cell invasion under the dosage of 20, 30, 60 micromol x L(-1). Flow cytometry also showed that curcumin can influence the distribution of cell cycle of SCC-4 cell with the dosage of 20, 30, 60 micromol x L(-1). And the dosage of 30 micromol x L(-1) curcumin could lead to the recruitment of alpha-tubulin. cDNA microarray showed that 87 genes were activated and 198 genes were inhibited with the effect of curcumin. These results were validated by the real time quantitative RT-PCR.

CONCLUSIONAccording to the results, it suggests that curcumin has the potential as the leading compound for anti-cancer proliferation and invasion in oral cancer treatment, and cdc27, EGFR substrate 15, PPAR-alpha and H2A histone may play an important role among this multiple anticancer-targeting ability.

Objective:To explore the experience of self-management dilemma ofadults with emerging ankylosing spondylitis, and to provide reference for the construction of self-management intervention strategies for emerging adults with ankylosing spondylitis.Methods:Descriptive phenomenology was used to conduct in-depth interviews with 14 adults with emerging ankylosing spondylitis in the Rheumatology and Immunology Department of Drum Tower Hospital Affiliated to Medical College of Nanjing University from August 2022 to March 2023. The interview data were analyzed by Colaizzi′s seven-step analysis method.Results:A total of 14 patients completed the interview,10 males, 4 females, aged 21-30 years. In adults with emerging ankylosing spondylitis, there were dilemmas of role maladjustment and disease management disorder, including role maladjustment of disease management and social role maladjustment. Barriers to disease management included weak self-management awareness, insufficient support for self-management information, inadequate self-management skills, and poor compliance with self-management behaviors.Conclusions:The role adaptation and self-management ability of adults with emerging ankylosing spondylitis are seriously inadequate. It is urgent to construct health management strategies for adults with emerging ankylosing spondylitis to help them improve the level of role adaptation and disease management.

Although mesenchymal stem cells (MSCs) are increasingly used to treat graft-versus-host disease (GVHD), their immune regulatory mechanism in the process is elusive. The present study aimed to investigate the curative effect of third-party umbilical cord blood-derived human MSCs (UCB-hMSCs) on GVHD patients after allogeneic hematopoietic stem cell transplantation (allo-HSCT) and their immune regulatory mechanism. Twenty-four refractory GVHD patients after allo-HSCT were treated with UCB-hMSCs. Immune cells including T lymphocyte subsets, NK cells, Treg cells and dendritic cells (DCs) and cytokines including interleukin-17 (IL-17) and tumor necrosis factor-alpha (TNF-α) were monitored before and after MSCs transfusion. The results showed that the symptoms of GVHD were alleviated significantly without increased relapse of primary disease and transplant-related complications after MSCs transfusion. The number of CD3(+), CD3(+)CD4(+) and CD3(+)CD8(+) cells decreased significantly, and that of NK cells remained unchanged, whereas the number of CD4(+) and CD8(+) Tregs increased and reached a peak at 4 weeks; the number of mature DCs, and the levels of TNF-α and IL-17 decreased and reached a trough at 2 weeks. It was concluded that MSCs ameliorate GVHD and spare GVL effect via immunoregulations.
