Analysis of pregnancy outcomes, disease progression, and risk factors in patients with undifferentiated connective tissue disease / 北京大学学报(医学版)

OBJECTIVE@#To investigate the fetal and maternal outcomes, risk factors of disease progression and adverse pregnancy outcomes (APOs) in patients with undifferentiated connective tissue disease (UCTD).@*METHODS@#This retrospective study described the outcomes of 106 pregnancies in patients with UCTD. The patients were divided into APOs group (n=53) and non-APOs group (n=53). The APOs were defined as miscarriage, premature birth, pre-eclampsia, premature rupture of membranes (PROM), intrauterine growth restriction (IUGR), postpartum hemorrhage (PPH), and stillbirth, small for gestational age infant (SGA), low birth weight infant (LBW) and birth defects. The differences in clinical manifestations, laboratory data and pregnancy outcomes between the two groups were compared. Logistic regression analysis was performed to analyze the risk factors for APOs and the progression of UCTD to definitive CTD.@*RESULTS@#There were 99 (93.39%) live births, 4 (3.77%) stillbirths and 3 (2.83%) miscarriage, 20 (18.86%) preterm delivery, 6 (5.66%) SGA, 17 (16.03%) LBW, 11 (10.37%) pre-eclampsia, 7 (6.60%) cases IUGR, 19 (17.92%) cases PROM, 10 (9.43%) cases PPH. Compared with the patients without APOs, the patients with APOs had a higher positive rate of anti-SSA antibodies (73.58% vs. 54.71%, P=0.036), higher rate of leukopenia (15.09% vs. 3.77%, P=0.046), lower haemoglobin level [109.00 (99.50, 118.00) g/L vs. 124.00 (111.50, 132.00) g/L, P < 0.001].Multivariate Logistic regression analysis showed that leucopenia (OR=0.82, 95%CI: 0.688-0.994) was an independent risk factors for APOs in UCTD (P=0.042). Within a mean follow-up time of 5.00 (3.00, 7.00) years, the rate of disease progression to a definite CTD was 14.15%, including 8 (7.54%) Sjögren's syndrome, 4 (3.77%) systemic lupus erythematosus (SLE), 4 (3.77%) rheumatoid arthritis and 1 (0.94%) mixed connective tissue disease. Multivariate Cox proportional risk regression analysis showed that Raynaud phenomenon (HR=40.157, 95%CI: 3.172-508.326) was an independent risk factor for progression to SLE.@*CONCLUSION@#Leukopenia is an independent risk factor for the development of APOs in patients with UCTD. Raynaud's phenmon is a risk factor for the progression of SLE. Tight disease monitoring and regular follow-up are the key measures to prevent adverse pregnancy outcomes and predict disease progression in UCTD patients with pregnancy.

Preparation of tanshinone Ⅱ_A-glycyrrhetinic acid solid lipid nanoparticles and its inhibitory effect on acne / 中国中药杂志

The optimal prescription of tanshinone Ⅱ_A(TSN)-glycyrrhetinic acid(GA) solid lipid nanoparticles(GT-SLNs) was explored and evaluated in vivo and in vitro, and its effect on acne after oral administration was investigated. The preparation processing and prescription were optimized and verified by single factor and response surface methodology. The in vitro release of GA and TSN in GT-SLNs was determined by ultra-performance liquid chromatography(UPLC). The effect of GT-SLNs on acne was investigated by the levels of sex hormones in mice, ear swelling model, and tissue changes in sebaceous glands, and the pharmacokinetics was evaluated. The 24-hour cumulative release rates of GA and TSN in SLNs were 65.87%±5.63% and 36.13%±2.31% respectively. After oral administration of GT-SLNs and the mixture of GA and TSN(GT-Mix), the AUC_(0-t) and AUC_(0-∞) of TSN in GT-SLNs were 1.98 times and 4.77 times those in the GT-Mix group, respectively, and the peak concentration of TSN in the GT-SLNs group was 17.2 times that in the GT-Mix group. After intragastric administration of GT-SLNs, the serum levels of testosterone(T) and the ratio of testosterone to estradiol(T/E2) in the GT-SLNs group significantly declined, and the sebaceous glands of mice were atrophied to a certain extent. The results demonstrated that obtained GT-SLNs with good encapsulation efficiency and uniform particle size could promote the release of GA and TSN. GT-SLNs displayed therapeutic efficacy on acne manifested by androgen increase, abnormal sebaceous gland secretion, and inflammatory damage.

Prognostic value of primary tumor surgery in seminoma patients with distant metastasis at diagnosis: a population-based study / 亚洲男科学杂志(英文版)

The aims of this study were to determine the prognostic value of primary tumor surgery and identify optimal candidates for such surgery among patients with seminoma and distant metastasis at diagnosis. We identified 521 patients with seminoma and distant metastasis at diagnosis between 2004 and 2014 from the Surveillance, Epidemiology, and End Results database. Among these patients, 434 had undergone surgery, whereas 87 had not. The prognostic value of primary tumor surgery was assessed by Kaplan-Meier methods, log-rank analyses, and multivariate Cox's proportional hazards model. Survival curves and forest plots were also plotted. Survival analysis indicated that patients who underwent surgery had a better 5-year overall survival and cancer-specific survival than those who did not. Multivariate analyses demonstrated that primary tumor surgery is an independent prognostic factor for overall survival and cancer-specific survival, along with age at diagnosis, M stage, and marital status. In addition, primary tumor surgery still had considerable prognostic value in the subgroup of patients with lymph node metastasis. Further, forest plots demonstrated that patients with M1a stage, N1 or N2-3 stage, and a younger age at diagnosis (<60 years) may benefit from primary tumor surgery. In conclusion, our findings indicate that primary tumor surgery is correlated with improved survival in patients with seminoma and distant metastasis. Furthermore, primary tumor surgery is an independent prognostic indicator for patients with seminoma and distant metastasis.

Identification of seven long noncoding RNAs signature for prediction of biochemical recurrence in prostate cancer / 亚洲男科学杂志(英文版)

Accumulating evidence suggested that long noncoding RNAs (lncRNAs) possess a potential role in prostate cancer (PCa) diagnosis and prognosis. Rapid biochemical recurrence (BCR) is considered as a sign for clinical recurrence metastasis and PCa-specific mortality. Hence, the aim of the present study was to identify a lncRNA signature that can predict BCR of PCa accurately. Bioinformatics analysis, Kaplan-Meier analyses, Cox regression analyses, and Gene Set Enrichment Analysis (GSEA) were performed in a publicly available database with 499 PCa tissues and 52 matched normal tissues. A signature was identified. All these lncRNAs were differentially expressed between tumor and normal tissues and differentially expressed between high Gleason score and low Gleason score tissues. Furthermore, we developed a seven lncRNAs signature that can predict PCa BCR. Patients classified into low-risk group showed better BCR survival significantly than the patients in the high-risk group (hazard ratio = 0.32, 95% CI: 0.20-0.52, concordance index = 0.63). The area under the curve was 0.68 for BCR. The signature also had good discrimination for BCR in men with Gleason 7 PCa. In conclusion, our results suggest that the seven lncRNAs signature is a new biomarker of BCR and high risk in PCa. In addition, the individual lncRNA warrants further study to uncover the associated mechanisms of PCa progression and the signature could be used to design direct clinical trials for adjuvant therapy.

Antitumor activity of recombinant antimicrobial peptide penaeidin-2 against kidney cancer cells / 华中科技大学学报（医学）（英德文版）

Penaeidin-2 (Pen-2) is an important antimicrobial peptide derived from the Pacific white shrimp, Penaeus vannamei, and possesses both antibacterial and antifungal activities. Recent studies suggest that recombinant penaeidins show similar activities to the native Pen-2 protein. Previous researches have shown that some antimicrobial peptides (AMPs) exhibit cytotoxic activity against cancer cells. To date, there have been no studies on the antitumor effects of Pen-2. This study evaluated the potential of recombinant pen-2 (rPen-2) in the selective killing of kidney cancer cell lines ACHN and A498, and its action mechanism. MTT assays found the maximal growth inhibition of HK-2, ACHN and A498 cells treated with 100 μg/mL rPen-2 at 48 h was 13.2%, 62.4%, and 70.4%, respectively. DNA-specific fluorescent dye staining showed a high percentage of apoptosis on cancer cells. Flow cytometry revealed that the apoptosis rate of HK-2, ACHN and A498 cells was 15.2%, 55.2%, and 61.5% at 48 h respectively, suggesting that rPen-2 induced higher apoptosis rate in cancer cells than in HK-2 cells. Laser confocal scanning microscopy demonstrated that the plasma membrane was the key site where rPen-2 interacted with and destroyed tumor cells. Scanning electron microscopy showed the morphologic changes of the cell membranes of kidney cancer cells treated with rPen-2. These results suggest that rPen-2 is a novel potential therapeutic agent that may be useful in treating kidney cancers.

Influence of obesity on clinicopathological characteristics in patients with clinically localized prostate cancer / 中华外科杂志

<p><b>OBJECTIVE</b>To investigate the influence of anthropometric measures of obesity, including body mass index (BMI), abdominal subcutaneous adipose tissue and visceral adipose tissue, on pathological characteristics in patients with clinically localized prostate cancer.</p><p><b>METHODS</b>From January 2006 to March 2013, the 413 patients of prostate cancer who received radical prostatectomy (RP) and their clinical and pathological data had been collected. The median age for the entire cohort was 68 years, which ranged from 48 to 78 years. All patients were diagnosed with prostate cancer before surgery and the Gleason score ranged from 4 to 10 (median 7). Anthropometric measures of abdominal adiposity including anterior abdominal fat, posterior abdominal fat and anteroposterior diameter were measured from the T2 weighted sagittal localization images of MRI scans and subcutaneous adipose tissue and the percentage of visceral adipose tissue were calculated. The patients' clinical and pathologic characteristics across BMI groups were compared used Student's t test for continuous variables or chi-squared test for categorical variables. Moreover, univariable and multivariable logistic regression models were used to address the influence of anthropometric measures of obesity on pathological outcomes.</p><p><b>RESULTS</b>The BMI ranged from 14.2 to 34.0 kg/m(2) and the median value was 23.8 kg/m(2). The abdominal subcutaneous adipose tissue ranged from 12.6 to 60.3 mm and the median value was 31.4 mm. The percentage of visceral adipose tissue ranged from 71.1% to 92.1% and the median value was 83.8%. In RP specimens, Gleason score ≥ 8 was observed in 141 patients (34.1%), pathological tumor stage was T3a in 69 patients (16.7%) and pathological tumor stage was T3b in 78 patients (18.9%). Positive surgical margin and lymph node involvement were observed in 71(17.2%) and 38(9.2%) patients, respectively. Although univariate analysis showed that BMI ≥ 25 kg/m(2) was associated with pathological Gleason score ≥ 8 (OR = 1.413, P = 0.035), this positive correlation disappeared in multivariate analysis(P = 0.095). In multivariate analysis, the percentage of visceral adipose tissue was significantly associated with pathological Gleason score (OR = 9.618, P = 0.000), extracapsular extension (OR = 6.750, P = 0.002) and seminal vesicle invasion (OR = 4.419, P = 0.007) after adjusting for patient age, PSA level, clinical stage and biopsy Gleason score.</p><p><b>CONCLUSIONS</b>Anthropometric measures of abdominal adiposity was more sophisticated than simple BMI to evaluate the risk of obesity with regard to the aggressiveness of prostate cancer. The percentage of visceral adipose tissue was an independent factor for pathological Gleason score, extracapsular extension and seminal vesicle invasion in RP specimens.</p>

Camouflage treatment in adult skeletal Class III cases by extraction of two lower premolars / 대한치과교정학회지

OBJECTIVE: The purpose of this study was to evaluate the dentoskeletal and soft tissue profile changes after extraction of two lower first or second premolars in "borderline" adult skeletal Class III cases. METHODS: Twenty-eight patients with "borderline" skeletal Class III malocclusion were studied. All of them were treated by extraction of two lower first or second premolars. Lateral cephalometric radiographs taken at the start and end of treatment were analysed. Twenty-five cephalometric variables were calculated and paired t-tests were performed. RESULTS: After treatment, no significant changes were noted in the skeletal parameters (p > or = 0.05). Regarding the dental parameters, the L1-MP angle decreased by 8.1degrees, the U1-L1 angle increased by 7.7degrees (p < 0.01), the overjet distance increased by 5.7 mm (p < 0.01), the L1-NB angle decreased by 7.3degrees and the L1-NB distance decreased by 4.8 mm (p < 0.01). The soft tissue parameters of Li-E, Li-H and Li-RL2 distance decreased by 3.2 mm, 3.4 mm and 4.1 mm respectively (p < 0.01). CONCLUSIONS: Orthodontic camouflage treatment by extraction of two lower first or second premolars provides a viable treatment alternative for "borderline" skeletal Class III cases to achieve a good occlusal relationship.

Relationship between expression of GYPC and TRIP3 genes and prognosis of acute lymphoblastic leukemia in children / 中国当代儿科杂志

<p><b>OBJECTIVE</b>To study the relationship of GYPC and TRIP3 gene expression and the prognosis of acute lymphoblastic leukemia (ALL) in children in order to explore the molecular biological mechanisms of recurrence and remission of ALL.</p><p><b>METHODS</b>Thirty-eight newly diagnosed ALL children were enrolled. Of the 38 patients, 31 achieved complete remission (CR) and 12 relapsed. Semi-quantitative RT-PCR was employed to measure blood GYPC and TRIP3 gene expression. Twenty blood samples from normal children were used as controls.</p><p><b>RESULTS</b>Blood GYPC expression in newly diagnosed ALL children was significantly higher than that in the control group (p<0.01) and the CR group (p<0.01). The expression of GYPC gene in the CR group was similar to that in the control group. Other than the control group (p<0.01) and the CR group (p<0.01), the GYPC expression of the relapse group was significantly higher than that in the newly diagnosed group (p<0.01). The CR group showed lower GYPC gene expression than the nonjremission group before treatment (p<0.05). Blood expression of TRIP3 gene in the newly diagnosed and the relapse groups was significantly lower than that in the control group (p<0.05). The CR group had increased TRIP3 gene expression compared with the control group (p<0.01) as well as the newly diagnosed and the relapse groups (p<0.01). Of the 38 newly diagnosed ALL children, the patients with positive TRIP3 expression showed higher remission rate than those with negative TRIP3 (p<0.05). The TRIP3 gene expression before treatment in patients who achieved CR was higher than that in non-remission patients (p<0.05).</p><p><b>CONCLUSIONS</b>A high GYPC gene expression is associated with an unfavorable outcome, in contrast, a high TRIP3 gene expression is associated with a favorable outcome in childhood ALL.</p>

Expression of nm23 H(1) gene in childhood acute lymphoblastic leukemia and the relationship between nm23 H(1) expression and immunophenotype / 中国当代儿科杂志

<p><b>OBJECTIVE</b>To study the expression of nm23-H(1) gene in children with acute lymphoblastic leukemia (ALL) and the relationship between nm23-H(1) expression and immunophenotype.</p><p><b>METHODS</b>nm23-H(1) expression was measured by semiquantitative RT-PCR in children with ALL (newly diagnosed, n = 40; remission, n = 32; relapse, n = 16; refractory, n = 3). Twenty normal children served as the control group. The relationship between nm23-H(1) expression and immunophenotype was evaluated.</p><p><b>RESULTS</b>The expression of nm23-H(1) in the newly diagnosed ALL group was significantly higher than that in the control (p<0.01) and the remission groups (p<0.01). There was no difference in the nm23-H(1) expression between the remission and the control groups. The expression of nm23-H(1) in the relapse group was significantly higher than that in the control (p<0.01) and the remission groups (p<0.01), and similar to that in the newly diagnosed ALL group. The three children with refractory ALL had higher nm23-H(1) expression. Both the positive rate and expression of nm23-H(1) in children with T-lineage ALL were higher than in children with B-lineage ALL (p<0.05).</p><p><b>CONCLUSIONS</b>The expression level of nm23-H(1) varies with the stages of ALL. Newly diagnosed, relapsed and refractory ALL children have higher nm23-H(1) expression. High nm23-H(1) expression may be associated with a poor prognosis and relapse. A higher expression of nm23-H(1) in children with T-ALL may be contributed to a low remission rate and a poor prognosis.</p>
