OBJECTIVETo explore the effect of Qiling Decoction (QD) combined highly active antiretroviral treatment (HAART) on expression levels of peripheral blood Th17 and Treg cells in HIV/AIDS patients.

METHODSTotally 55 HIV/AIDS patients were randomly assigned to the treatment group (28 cases) and the combination group (27 cases). Besides, 21 HIV negative patients were recruited as the healthy control group. Those in the treatment group received HARRT alone, while those in the combination group received HAART combined QD. The observation lasted for 24 weeks. Meanwhile, according to peripheral blood CD4+ T cell counts before treatment, HIV/AIDS patients were assigned to three subgroups. For patients in subgroup 1, 1 cells/microL < CD4+ T cell counts < or = 100 cells/microL; For patients in subgroup 2, 101 cells/microL < CD4+ T cell counts < or = 200 cells/lL; For patients in subgroup 3, 201 cells/microL < CD4+ T cell counts < or = 350 cells/microL. Expression of peripheral blood Th17 and Treg cells, and number of CD4+ T cell counts were detected using flow cytometry (FCM)in HIV/AIDS patients at the pre-treatment baseline, week 4, 12, and 24, as well as those in the healthy control group.

RESULTSCompared with the healthy control group, CD4+ T cell counts and the baseline expression level of Th17 cells in the peripheral blood of HIV/AIDS patients significantly decreased, the expression level of Treg cells significantly increased P < 0.01). Compared with before treatment in the same group, CD4+ T cell counts all increased at week 4, 12, and 24 in the two treatment groups, showing statistical difference (P < 0.05, P < 0.01). There was no statistical difference in the effective rate at various CD4+ T cell levels between the two groups (P > 0.05). There was no statistical difference in expression levels of Th17 and Treg cells between the combination group and the treatment group at any time point (all P >0.05). The Th17/Treg ration significantly increased in the combination group after 24 weeks of treatment, showing statistical difference when compared with the treatment group (U = 2.135, P = 0.038).

CONCLUSIONQD could improve the immune balance of Th17/Treg cells, which might be one of its mechanisms for improving HIV/AIDS patients' immunity.

Purpose: Sleep quality was considered a priority concern facing pregnant women. Conventional wisdom argues that good sleep quality benefits pregnant women and their fetuses. The aim of this study is to assess the effects of a specific exercise program on the　sleep quality in pregnant women. Methods: Searches were executed in seven databases since their inceptions until February 28, 2019, for randomized controlled trials evaluating the effects of an exercise program on the sleep quality and insomnia in pregnant women. A random-effects model was applied for meta-analysis, and odds ratio, mean differences (MDs), and 95% confidence intervals (CIs) are shown as parts of outcomes. Results: Seven studies were included for meta-analysis. Compared with their not-exercising counterparts, analyses showed that regularly exercising women had significantly enhanced sleep quality, with an odds ratio of 6.21 (95% CI, 2.02–19.11;p = .001; I2 = 80.2%), with a standardized MD of −0.93 (95% CI, −1.19 to −0.67; p < .001; I2 = 30.0%). However, exercising women showed no significant insomnia improvement, with an standardized MD of −2.85 (95% CI, −7.67 to 1.98; p = .250; I2 = 97.0%), relative to their not-exercising counterparts. Conclusion This research indicated that exercise has a positive impact on the sleep quality of pregnant women. Despite the aforementioned positive impact on sleep quality, the present study did not find evidence to support that exercise may also improve insomnia for pregnant women.

OBJECTIVEThe purpose of this study was to investigate the correlation between gene mutation and gene copy number and their association with the clinical profiles and pathological features in Chinese patients with non-small cell lung cancer (NSCLC).

METHODSSurgical specimens of cancer tissue were collected from 118 NSCLC patients. Gene mutations in exon 19 and exon 21 were detected by real-time PCR and gene copy number was detected by fluorescence in situ hybridization (FISH). Chi-square (χ(2)) test was performed to analyze the correlation between EGFR mutation and gene copy number, and explore their association with clinicopathological features in the NSCLC patients.

RESULTSThe mutation frequency in EGFR was 41.5% (49/118). EGFR mutations occured in 50.0% (48/96) of patients with adenocarinoma and 5.0% (1/20) of patients with squamous cell carcinoma. EGFR gene high copy number was detected in 70.3% (83/118)of the patients. The FISH-positive rate was 78.1% (75/96) in adenocarcinoma and 35.0% (7/20) in squamous cell carcinoma. EGFR mutation and high copy number mainly occurred in the adenocarcinoma, advanced stage, female gender, and non-smoking patients. There was a significant correlation between EGFR gene mutation and gene high copy number.

CONCLUSIONSEGFR gene mutation and gene high copy number are more common in Chinese NSCLC patients with adenocarcinomas, advanced stage, non-smokers and females. There is a significant correlation between gene mutation and gene high copy number. Combined analysis of EGFR mutation and gene copy number by FISH may provide a superior approach in selecting patients who may benefit from anti-EGFR target therapy.

In this study, Actin, 18S rRNA, PAL, GAPDH and CPR of Artemisia annua were selected as candidate reference genes, and their gene-specific primers for real-time PCR were designed, then geNorm, NormFinder, BestKeeper, Delta CT and RefFinder were used to evaluate their expression stability in the leaves of A. annua under treatment of different concentrations of Cd, with the purpose of finding a reliable reference gene to ensure the reliability of gene-expression analysis. The results showed that there were some significant differences among the candidate reference genes under different treatments and the order of expression stability of candidate reference gene was Actin > 18S rRNA > PAL > GAPDH > CPR. These results suggested that Actin, 18S rRNA and PAL could be used as ideal reference genes of gene expression analysis in A. annua and multiple internal control genes were adopted for results calibration. In addition, differences in expression stability of candidate reference genes in the leaves of A. annua under the same concentrations of Cd were observed, which suggested that the screening of candidate reference genes was needed even under the same treatment. To our best knowledge, this study for the first time provided the ideal reference genes under Cd treatment in the leaves of A. annua and offered reference for the gene expression analysis of A. annua under other conditions.

The aim of this study was to explore the effects of the stromal cell-derived factor (SDF-1) and chemokine receptors (CXCR4) on chemotaxis of cord blood AC133(+) cells. The optimal SDF-1 concentration was determined in Transwell System. The cell migration was calculated from the number of cells passing through polycarbonate membrane with 8 microm pore. The expressions of CXCR4 in fresh and cultured cord blood AC133(+) cells were analyzed by flow cytometry with two-color direct immunofluorescence. The results showed that the chemotactic rate of fresh cord blood AC133(+) cells increased along with increasing concentrations of SDF-1, however, it tended to be stable when the concentration of SDF-1 reached 150 ng/ml. There was no difference in the chemotactic rate of cord blood AC133(+) cells between the group with SDF-1 adding CXCR4-blocking antibody and the group without SDF-1. When AC133(+) cells were cultured in vitro with hemopoietic growth factors, the expression of CXCR4 increased at the early stage, but decreased gradually along with time extending. In conclusion, there was correlation between the chemotactic rate of AC133(+) cells and the expression of chemokine receptor CXCR4.
