Background: Studies have indicated that statins influence the risks and mortality rates of several types of solid tumors. However, the association between statin use and survival in patients with colorectal cancer (CRC) remains unclear. Methods: We searched the PubMed and Embase databases for relevant studies published up to September 2014 that assessed statin use and CRC prognosis. The primary outcomes were overall survival (OS) and cancer-specific survival (CSS). The secondary outcomes were disease-free survival (DFS) and recurrence-free survival (RFS). Hazard ratios (HRs) and 95% confidence intervals (CIs) were extracted and pooled with Mantel-Haenszel randomeffect modeling. All statistical tests were two-sided. Results: Four studies on post-diagnosis statin therapy and five studies on pre-diagnosis statin use were included in our meta-analysis of 70,608 patients. Compared with the non-users, the patients with post-diagnosis statin use gained survival benefits for OS (HR 0.76; 95% CI: 0.68 to 0.85, P<0.001) and CSS (HR 0.70; 95% CI: 0.60 to 0.81, P<0.001). In addition, we observed that pre-diagnosis statin use prolonged the survival of patients with CRC for OS (HR 0.70; 95% CI: 0.54 to 0.91, P=0.007) and CSS (HR 0.80; 95% CI: 0.74 to 0.86, P<0.001). However, we did not observe a survival benefit for DFS (HR 1.13; 95% CI: 0.78 to 1.62, P=0.514) or RFS (HR 0.98; 95% CI: 0.36 to 2.70, P=0.975) in the CRC patients with post-diagnosis statin use. Conclusions: Statin use before or after cancer diagnosis is related to reductions in overall and cancer-specific mortality in colorectal cancer survivors. © 2015 Cai et al.

Acute kidney injury (AKI) is an abrupt loss of kidney function. Severe AKI requires renal replacement therapy and has high mortality. Leonurine (LEO), an alkaloid isolated from Leonurus cardiaca, has shown biological effects such as antioxidant, anticoagulant, and anti-apoptosis. We have examined the effect of LEO on lipopolysaccharide (LPS)-induced AKI in mice and further studied the mechanism involved. Blood urea nitrogen (BUN), creatinine and cytokine were estimated in the serum or tissue. Kidney tissue specimens were used for biochemical estimations of lipid peroxides (LPO), reduced glutathione (GSH), and reactive oxygen species (ROS). The effects of LEO on LPS-induced renal tissue damage were detected by hematoxylin and eosin (HE) stain and electron microscopy. The production of cytokines in the tissue and blood was measured by ELISA. Protein phosphorylation and protein subcellular localization were tested by Western blot. LEO is protected against LPS-induced AKI, improved animal survival and maintained the redox balance. The beneficial effects of LEO were accompanied by the down-regulation of TNF-α, IL-1, IL-6, IL-8, KIM-1 expression and by the inhibition of the phosphorylation of IκBα and p65 translocalization. These results suggest that LEO may suppress NF-κB activation and inhibit pro-inflammatory cytokine production via decreasing cellular ROS production. Accumulating studies have demonstrated that LEO reduces kidney injury and protects renal functions from LPS-induced kidney injury. © 2014 Elsevier B.V.

OBJECTIVE: To investigated the effect and mechanism of Fangjihuangqi Tang (FHT) on lower urinary tract dysfunction induced by benign prostatic hyperplasia (BPH) in rats. METHODS: Male rats were randomly divided into seven groups: normal, model, finasteride (0.5 mg/kg), terazosin (0.5 mg/kg), and FHT (10, 5, 2.5 g/kg). Rats were administered testosterone (0.5 mg sc) for 6 weeks after orchiectomy, excluding the normal group. All rats were intragastrically administered assigned drugs for 4 weeks from the third week. Urodynamics were assessed in rats under anesthesia. Serum dihydrotestosterone (DHT) and prostatic acid phosphatase (PAP) were measured. The prostate index (PI), bladder index (BI), and pathological detection were evaluated. RESULTS: In the model group, the PI, BI, serum DHT, serum PAP, threshold pressure (TP), micturition pressure (MP), and residual urine volume (RV) were significantly higher. Moreover, inter-micturition duration (IMD) was significantly lower and the prostatic and bladder showed obvious pathological changes. The IMD was significantly higher, while BI, TP, MP, and RV were significantly lower and bladder pathological changes were alleviated in the FHT (10, 5 g/kg), finasteride, and terazosin groups. The PI, DHT, and PAP were significantly lower in the finasteride group, but they did not change significantly in the FHT (10, 5, 2.5 g/kg) and terazosin groups. CONCLUSION: FHT could relieve symptoms of lower urinary tract dysfunction in BPH rats but with no apparent effect on reducing the volume of the enlarged prostate itself. © 2013 JTCM.

Attention deficit/hyperactivity disorder (ADHD) is one of the most common psychiatric disorders of childhood. Despite its prevalence, the critical factors involved in its development remain to be identified. It was recently suggested that epigenetic mechanisms probably contribute to the etiology of ADHD. The present study was designed to examine the associations of epigenetic markers with ADHD among Chinese Han children, aiming to establish the prediction model for this syndrome from the epigenetic perspective. We conducted a pair-matching case-control study, and the ADHD children were systematically evaluated via structured diagnostic interviews, including caregiver interviews, based on the Diagnostic and Statistical Manual of Mental Disorders, 4th edition, revised criteria (DSM-IV-R). The expression levels of risk genes DAT1, DRD4, DRD5, as well as their promoter methylation, were determined respectively, followed by the expression profiles of histone-modifying genes p300, MYST4, HDAC1, MeCP2. The multivariate logistic regressions were performed to establish ADHD prediction models. All of the seven genes tested were identified as risk factors for ADHD. The methylation of one critical CpG site located upstream of DRD4 was shown to affect its transcription, suggesting a role in ADHD's development. Aberrant DNA methylation and histone acetylation were indicated in ADHD patients. In addition, a prediction model was established using the combination of p300, MYST4 and HDAC1, with the accuracy of 0.9338. This is, to our knowledge, the first study to clearly demonstrate the associations between epigenetic markers and ADHD, shedding light on the preliminary diagnosis and etiological studies of this widespread disorder. © 2015 Elsevier Ltd.

Bladder cancer is a common genitourinary malignant disease worldwide. Abundant evidence has shown that cigarette smoke (CS) is a crucial risk factor for bladder cancer. Nevertheless, the mechanism underlying the relationship between cigarette smoking and bladder cancer remains unclear. In the present study, we investigated the effects of cigarette smoke extract (CSE) on mitogen-activated protein kinase (MAPK) pathway activation and EMT alterations in human bladder cancer T24 cells, and the preventive effect of extracellular regulated protein kinases 1 and 2 (ERK1/2) inhibitor U0126 was further examined. Our results illustrated that CSE exposure induced morphological change of human bladder cancer T24 cells, enhanced migratory and invasive capacities, reduced epithelial marker expression and elevated mesenchymal marker expression. Meanwhile, exposure of T24 cells to CSE resulted in activation of ERK1/2 pathway as well as activator protein 1 (AP-1) proteins. Interestingly, treatment with ERK1/2 inhibitor U0126 effectively abrogated CSE-triggered EMT and ERK1/2/AP-1 activation. These findings provide novel insight into the molecular mechanisms of CS-associated bladder cancer and may open up new avenues in the search for potential target of bladder cancer intervention.

To investigate the impact of mild hypothermia on the lipopolysaccharide (LPS)-induced expressions of Toll-like receptor 4 (TLR4), nuclear factor B (NF-B) and downstream inflammatory cytokines in BV-2 microglias.BV-2 cells cultured in vitro were divided into 33 Degrees Celsius-PBS, 33 Degrees Celsius-LPS, 37 Degrees Celsius-PBS and 37 Degrees Celsius-LPS groups. Real-time quantitative PCR was performed to detect the mRNA expressions of TLR4 and NF-B in BV-2 cells, Western blotting was performed to detect the protein expressions of TLR4 and NF-B in BV-2 cells, and ELISA to detect the levels of tumor necrosis factor (TNF-) and interleukin-1 (IL-1) in the culture medium.After LPS stimulated BV-2 cells, TLR4 pathway protein exhibited the trend of increasing firstly and decreasing afterwards, while the expression of NF-B protein in the pathway downstream continued to increase, and the release of inflammatory cytokines TNF- and IL-1 were significantly promoted. Mild hypothermia could significantly inhibit the transcription and expressions of TLR4 and NF-B as well as the release of inflammatory cytokines.The mild hypothermia could inhibit the LPS/TLR4 pathway in BV-2 cells, and depress the expressions of TNF- and IL-1.

Background: The one-stage procedure for treatment of older developmental dislocation of the hip (DDH) is used widely. However, the best age group for this operation is still unknown. The aims of our study were to evaluate middle-term outcomes of one-stage surgical treatment of a large number of patients with late-diagnosed DDH, and to explore the best age group for treatment. Methods: We retrospectively reviewed 652 patients with a total of 864 hip joints with DDH, all aged >18 months. All the hip joints were treated with one-stage procedures including open reduction, pelvic osteotomy, and femoral shortening. The patients were divided into three groups according to age at surgery: Group I: 1.5-2.5 years; Group II: 2.5-8 years; and Group III: >8 years. The latest clinical and radiographic outcomes, complications and avascular necrosis (AVN) of the femoral head were evaluated and compared among the three groups. Results: The mean age at surgery was 5.8 years (range: 1.5-13.2 years). The average time of follow-up was 6.2 years (range: 3.2-8.9 years). A total of 79.4% of good or excellent outcomes were obtained for clinical functional evaluation according to the McKay classification. For radiographic outcomes, 732 hips (84.7%) were classified as good or excellent according to the Severin classification. A total of 27.4% of all hips had a poor outcome according to the Kalamchi and MacEwen classification for AVN. The poorest outcomes were observed for clinical, radiographic and AVN results in Group III (p < 0.001). Compared with Group I, the better results for clinical and AVN outcomes were found in Group II (p < 0.001). However, similar clinical outcomes were observed between Groups I and II (p > 0.05). A significantly higher incidence of redislocation and residual acetabular dysplasia was observed in Tonnis grade II and III hip dislocation (p < 0.001). Conclusions: One-stage treatment of late-diagnosed DDH had a good outcome in young and middle group. Younger patients achieved better results than older patients. However, the best age group was 2.5-8 years. Tonnis grade II and III DDH is a risk factor for redislocation and residual acetabular dysplasia after the one-stage operation. © 2014 Ning et al.; licensee BioMed Central Ltd.

To improve the surgical outcome of hypospadias repair surgery, pre-operative hormonal stimulation (PHS) has been proposed. We conducted a meta-analysis to evaluate the impact of pre-operative hormonal stimulation (PHS) treatment on complication rates following hypospadias repair surgery.A comprehensive literature search up to 1st June 2015 was carried out for relevant studies. After literature identification and data extraction, relative ratio (RR) was calculated to compare post-operative complication rates. Heterogeneity among individual studies was tested using the Cochran chi-square Q test and quantified by calculating the I2 index. Meta-regression was applied to find potential affective factors.428 patients in 6 studies had undergone primary hypospadias repair, of which 171 (39.95%) received some form of Pre-Operative Hormonal Stimulation with human chorionic gonadotropin (HCG), dihydrotestosterone (DHT) or testosterone (T). They underwent 3 different types of surgical techniques, which included Onlay Island Flap (OIL) (277 patients), Tubularized Incised plate (TIP) (99 patients) and Koyanagi urethroplasty (52 patients). These 6 studies classified the complication rates based on PHS. The relative ratio (RR) for a complication occurring following PHS use was 1.18 (95%CI= 0.70-2.00, Z=0.91, P=0.539). Significant heterogeneity (I2 =47.1%,P=0.092) among various research literature was found and meta-regression was undertaken for the heterogeneity, but surgical technique, mean age of patients at time of surgery, types of PHS and the quality of studies were not the cause of heterogeneity.Use of T, DHT and HCG prior to hypospadias repair does not appear to increase the incidence of post-operative complications, but there is need for further investigation.

Recent studies have identified 10q24-rs17095355 as a susceptibility locus for biliary atresia (BA). To more precisely estimate the association between the rs17095355 polymorphism and BA risk, a meta-analysis was performed.A comprehensive search was conducted to examine all the eligible studies by electronic databases including Elsevier Science Direct, Pubmed, Google Scholar, China National Knowledge Infrastructure (CNKI) and Chinese Biomedical Literature (CBM) up to December 2015. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to assess the strength of the association.A total of 6 comparisons from 5 relevant studies involving 1000 patients and 3257 controls were included to analyze the association between rs17095355 and BA risk. The pooled OR for T allele of rs17095355 was 1.72 (95%CI 1.53-1.92, p<0.01) in BA. Stratification by ethnicity indicated the degree of risk of rs17095355 with BA susceptibility was similar in populations of Asian origin. The pooled OR was 1.81 (95%CI 1.60-2.06, p<0.01).This meta-analysis confirms the association of rs17095355 polymorphism and BA development, especially in Asians. More original studies with large sample are needed to replicate this genetic association in different ethnic groups.
