BACKGROUND: Sex reversal syndrome is a genetic anomaly caused by the disorder of sex development (DSD) with the characteristics of inconsistent phenotype normal penile size but small testes and infertility re- stulting from azoospermia. CASE: A male patient was diagnosed with the karyo- type of 45,XO/47,XXX/46,XX male sex reversal syn- drome with normal pubic hair and normal penile size, high levels of follicle-stimulating hormone and luteiniz- ing hormone, but small testes and infertility resulting from azoospermia. CONCLUSION: Sex reversal syndrome is a genetic con- dition caused by DSD. Many factors can lead to DSD, but the accurate mechanism has not been completely discovered. between gonadal sexuality and chromosome sexuality, including 46,XX male and 46,XY female for the most part, but the rare type 45,XO male also can be found. Approximately 80% of males with 46,XX present' with normal pubic hair and.

Protective effects of metformin on reproductive function in obese male rats induced by high-fat diet.

PURPOSE: The study aims to elucidate the changes in testicular spermatogenic function in high-fat diet (HFD)-induced obese rats and to evaluate the protective effects of metformin intervention. METHODS: Male Sprague-Dawley rats (n = 18) were randomly divided into a control group (standard diet), an HFD group, and a metformin group (HFD + metformin at 100 mg/kg, once daily by oral gavage). After 8 weeks, rats were euthanized, and the weights of body and testes were measured. Testis and epididymis were dissected and hematoxylin-eosin-stained for histopathological examination and semen parameter analysis. Blood samples were collected for assessment of sex hormones and metabolic parameters (serum glucose, insulin, and leptin). Spermatogenic cell apoptosis was accessed by TUNEL. RESULTS: Compared with the control group, the final body weight and weight gain were significantly higher in HFD rats, while the testicle weight and coefficients were lower. In HFD rats, metformin treatment induced weight loss and increased testicle weight (P < 0.05). In HFD rats, obvious pathological changes in the testicular tissue were characterized by small, atrophic, and distorted seminiferous tubules and destroyed basement membrane. Metformin treatment protected against the HFD-induced decrease in the number of spermatogonia, Sertoli cells, and Leydig cells (P < 0.05); ameliorated the HFD-induced increases in serum glucose, insulin, leptin, and estrogen; and decreased serum testosterone (P < 0.05) and reduced the rate of testicular cell apoptosis in obese male rats. Finally, metformin significantly improved semen parameters (including concentration, viability, motility, and normal morphology) in HFD rats (P < 0.05). CONCLUSIONS: HFD-induced obesity in rats results in detrimental effects on spermatogenesis, semen quality, endogenous hormones, and testicular cell apoptosis. Metformin intervention improved the semen parameters, possibly due to its effects on weight loss, increased testicular weight, reduced testicular cell apoptosis, and resulted in restoration of hormonal homeostasis and correction of metabolic disorder.

MiR-142-3p Regulates ILC1s by Targeting HMGB1 via the NF-κB Pathway in a Mouse Model of Early Pregnancy Loss.

OBJECTIVE: Innate lymphoid cells (ILCs) are a class of newly discovered immunocytes. Group 1 ILCs (ILC1s) are identified in the decidua of humans and mice. High mobility group box 1 (HMGB1) is predicted to be one of the target genes of miR-142-3p, which is closely related to pregnancy-related diseases. Furthermore, miR-142-3p and HMGB1 are involved in regulating the NF-κB signaling pathway. This study aimed to examine the regulatory effect of miR-142-3p on ILC1s and the underlying mechanism involving HMGB1 and the NF-κB signaling pathway. METHODS: Mouse models of normal pregnancy and abortion were constructed, and the alterations of ILC1s, miR-142-3p, ILC1 transcription factor (T-bet), and pro-inflammatory cytokines of ILC1s (TNF-α, IFN-γ and IL-2) were detected in mice from different groups. The targeting regulation of HMGB1 by miR-142-3p in ILC1s, and the expression of HMGB1 in normal pregnant mice and abortive mice were investigated. In addition, the regulatory effects of miR-142-3p and HMGB1 on ILC1s were detected in vitro by CCK-8, Annexin-V/PI, ELISA, and RT-PCR, respectively. Furthermore, changes of the NF-κB signaling pathway in ILC1s were examined in the different groups. For the in vivo studies, miR-142-3p-Agomir was injected in the uterus of abortive mice to evaluate the abortion rate and alterations of ILC1s at the maternal-fetal interface, and further detect the expression of HMGB1, pro-inflammatory cytokines, and the NF-κB signaling pathway. RESULTS: The number of ILC1s was significantly increased, the level of HMGB1 was significantly upregulated, and that of miR-142-3p was considerably downregulated in the abortive mice as compared with the normal pregnant mice (all P<0.05). In addition, miR-142-3p was found to drastically inhibit the activation of the NF-κB signaling pathway (P<0.05). The number of ILC1s and the levels of pro-inflammatory cytokines were significantly downregulated and the activation of the NF-κB signaling pathway was inhibited in the miR-142-3p Agomir group (all P<0.05). CONCLUSION: miR-142-3p can regulate ILC1s by targeting HMGB1 via the NF-κB signaling pathway, and attenuate the inflammation at the maternal-fetal interface in abortive mice.

Hyaluronic acid modified extracellular vesicles targeting hepatic stellate cells to attenuate hepatic fibrosis.

RATIONALE: Transforming growth factor-beta1 (TGF-ß1) plays a pivotal role in promoting hepatic fibrosis, pirfenidone (PFD) could inhibit TGF-ß1 signaling pathway to alleviate hepatic stellate cells (HSC) activation mediated hepatic fibrosis. The targeting delivery strategy of PFD to hepatic stellate cells is a challenge. Extracellular vesicles (EVs), cell-derived membranous particles are intraluminal nano-vesicles that play a vital role in intercellular communication, they also be considered as an ideal nano-carrier. METHODS: In this study, we developed a target strategy to deliver PFD to HSC with CD44 over-expression by EVs, hyaluronic acid (HA) modified DSPE-PEG2000 endows the active targeting ability of activated HSCs to PFD-loaded EVs. RESULTS: In both rat hepatic stellate cell line HSC-T6 and rat hepatocyte cell line BRL, HA@EVs-PFD demonstrated the capacity to down-regulate the expression of collagen-synthesis-related proteins and showed superior inhibition efficacy of HSC-T6 activation compared to free PFD. In hepatic fibrosis model, 4 weeks of HA@EVs-PFD treatment resulted in a reduction in liver collagen fibers, significant improvement in hepatic cell morphology, and amelioration of hepatic fibrosis. CONCLUSIONS: HA@EVs-PFD, as a drug delivery system that effectively targets and inhibits activated HSCs to treat hepatic fibrosis, holds promise as a potential therapeutic agent against hepatic fibrosis.

Genetic Evidence for a Causal Relationship Between Innate Leukocytes and the Risk of Digestive System Cancers in East Asians and Europeans.

Background: Peripheral traditional immune cell disorder plays an important role in cancer onset and development. The causal relationships between leukocytes prior to cancer and the risk of digestive system cancer remain unknown. This study assesses the causal correlations between leukocytes and digestive system cancer risk in East Asians and Europeans. Methods: Summary-level data on leukocyte-related genetic variation were extracted from Biobank Japan (107,964 participants) and a recent large-scale meta-analysis (563,946 participants). Summary-level data for the cancers were obtained from Biobank Japan (212,978 individuals) and the FinnGen consortium (178,802 participants). Univariable and multivariable Mendelian randomization (MR) analyses were performed on East Asians and Europeans separately. Results: Univariable MR analysis demonstrated the significant association between circulating eosinophil counts and risk of colorectal cancer (CRC) in East Asians (odds ratio (OR) = 0.80, 95% confidence interval (CI): 0.69 - 0.92, P = 0.002) and a suggestive relationship in the European population (OR = 0.86, 95% CI: 0.77 - 0.97, P = 0.013). An inverse suggestive association was observed between levels of basophils and the risk of gastric cancer (GC) in East Asians (OR = 0.83, 95% CI: 0.72 - 0.97, P = 0.019). The multivariable MR analysis showed the independent causal effect of eosinophil count on CRC risk in East Asians (OR = 0.72, 95% CI: 0.57 - 0.92, P = 0.009) and Europeans (OR = 0.80, 95% CI: 0.70 - 0.92, P = 0.002). Circulating basophils served as the negative causal factor in GC risk in East Asians (OR = 0.80, 95% CI: 0.67 - 0.94, P = 0.007). Conclusions: Our MR analyses revealed a genetic causal relationship between reduced blood eosinophils and an increased CRC risk in both Europeans and East Asians. Furthermore, our results suggested a causal association between decreased basophils and an elevated GC risk specifically in East Asians.

[Composition analyses of bilateral urinary tract calculis].

OBJECTIVE: To explore the composition of bilateral urinary tract calculi so as to guide treatments. METHODS: A total of 126 patients with bilateral urinary calculi were recruited to undergo percutaneous nephrolithotomy or ureteroscopes lithotripsy. And 256 extracted stones were analyzed by infrared spectrophotometry. RESULTS: The components of these stones were mainly mixture. The compositions included calcium oxalate (n = 214, 85%), carbonate apatite (n = 113, 45%), phosphate (n = 43, 17%) and uric acid (n = 28, 11%). And 63 patients had the same stone composition in bilateral urinary stones and 26 of them were of pure calcium oxalate, 2 phosphate while another 36 mixture. Different compositions were present in 60 patients with bilateral urinary stones. CONCLUSION: The compositions of bilateral urinary stones are not always identical in a patient. The overall patient status should be considered if one side urinary stone is treated according to the composition analysis results of another side counterpart.

[Transurethral plasmakinetic enucleation of prostate and suprapubic small cut in the treatment of high risk and senior patient with benign prostatic hyperplasia and bladder stones].

OBJECTIVE: To explore the safety and efficiency of transurethral plasmakinetic enucleation of prostate (TUPKEP) and suprapubic small cut in the treatment of high-risk and senior patients with benign prostatic hyperplasia and bladder stones. METHODS: A retrospective review was conducted for 68 high-risk and senior patients with benign prostatic hyperplasia and bladder stones. All of them were treated by TUPKEP and suprapubic small cut. RESULTS: Operation was successfully performed in all 68 cases. And there was no instance of transurethral resection syndrome, shock, myocardial infarct, cerebral infarction, cerebral hemorrhage, permanent urinary incontinence or surgical site infection. Seven patients with temporal urinary incontinence recovered at a mean time of (9.48 ± 1.52) days post-operation. The mean operative duration was (48.63 ± 4.14) min and the mean volume of blood loss (50.97 ± 5.33) ml. The changes of maximum flow rate (Qmax), international prostatic symptom score (I-PSS) and quality-of-life (QOL) were statistically significant before and after operation. Qmax increased from (4.56 ± 0.35) to (18.82 ± 1.65) ml/s (P < 0.001), I-PSS decreased form (21.96 ± 1.89) to (11.23 ± 0.86) (P = 0.018) and QOL decreased from (4.94 ± 0.35) to (1.95 ± 0.32) (P = 0.011). CONCLUSION: The approach of TUPKEP and suprapubic small cut is both safe and effective in the treatment of high-risk and senior patient with benign prostatic hyperplasia and bladder stones and should be widely applied.

Role of galectin-3 in cardiac dysfunction induced by subarachnoid hemorrhage.

Subarachnoid hemorrhage (SAH) is a severe acute cerebrovascular event that not only impairs the central nervous system but also negatively affects various other organs, including the heart. The underlying mechanisms, however, remain unclear. In this study, we discovered that mice with SAH exhibited significant cardiac injuries, such as extended QT and QTc intervals, cardiac fibrosis, and reduced cardiac ejection fractions. This phenomenon was accompanied by increased galectin-3 expression in the cardiac ventricle and can be reversed by galectin-3 inhibitor TD139. Interestingly, we also observed increased co-expression of galectin-3 in macrophage within the heart tissue of SAH mice. Additionally, when macrophage activation was suppressed using the beta-blocker propranolol, cardiac function improved, and galectin-3 expression in the cardiac tissue decreased. Collectively, our findings offer new insights into the role of galectin-3 in SAH-related cardiac dysfunction and suggest a macrophage-galectin-3 axis as a potential therapeutic strategy.

Combination coating of chitosan and anti-CD34 antibody applied on sirolimus-eluting stents can promote endothelialization while reducing neointimal formation.

BACKGROUND: Circulating endothelial progenitor cells (EPCs) capture technology improves endothelialization rates of sirolimus-eluting stents (SES), but the problem of delayed re-endothelialization, as well as endothelial dysfunction, has still not been overcome. Therefore, we investigated whether the combination coating of hyaluronan-chitosan (HC) and anti-CD34 antibody applied on an SES (HCASES) can promote endothelialization, while reducing neointimal formation and inflammation. METHODS: Sirolimus-eluting stents(SES), anti-CD34 antibody stents (GS) and HC-anti-CD34 antibody combined with sirolimus-eluting stents (HCASES) were deployed in 54 normal porcine arteries and harvested for scanning electron microscopy (SEM) and histological analysis. The ratio of endothelial coverage above the stents was evaluated by SEM analysis at 7, 14 and 28 days. The percentage of in-stent stenosis was histologically analyzed at 14 and 28 days. RESULTS: SEM analysis at 7 days showed that endothelial strut coverage was increased in the HCASES group (68±7%) compared with that in the SES group (31±4%, p=0.02). At 14 days, stent surface endothelialization, evaluated by SEM, showed a significantly higher extent of endothelial coverage above struts in the GS (95 ± 2%) and the HCASES groups (87±4%) compared with that in the SES group (51±6%, p=0.02). Histological examination showed that the percentage of stenosis in the HCASES group was not significantly different to that of the SES and GS groups (both p> 0.05). At 28 days, there was no difference in the rates of endothelial coverage between the HCASES and GS groups. The HCASES group showed less stenosis than that in the GS group (P < 0.05), but it was not significantly different from the SES group (P=0.068). CONCLUSIONS: SEM and histology demonstrated that HCASESs can promote re-endothelialization while enhancing antiproliferative effects.

The Effect and Safety of Thunder-Fire Moxibustion for Low Back Pain: A Meta-Analysis of Randomized Controlled Trials.

Background: Low back pain (LBP) is considered the leading cause of people living with years of disability worldwide. Notably, thunder-fire moxibustion (TFM) is a new type of moxibustion, which has been widely applied to treat pain syndromes for thousands of years. This study aims to provide evidence to evaluate the effect and safety of TFM in treating LBP. Methods: A systematic search of PubMed, Web of Science, the Cochrane Library, Embase, EBSCO, CNKI, Wanfang Data, CBM, and VIP (until April 2021) was used to identify studies reporting pain intensity, disability, Japanese Orthopedic Association (JOA) score, and quality of life in patients with LBP. Randomized controlled trials (RCTs), which compared TFM and other therapies in LBP, were included. Meanwhile, methodological quality was evaluated using the Cochrane criteria for risk of bias, and the level of evidence was rated utilizing the GRADE approach. Results: Twenty-one RCTs, including 2198 patients, satisfied the inclusion criteria. Compared with other therapies, the effect of TFM was statistically significant, pain intensity decreased (SMD = 0.94; 95% CI (0.74, 1.14); p < 0.00001), disability improved (SMD = 1.39; 95% CI (0.19, 2.59); p=0.02), and the JOA score increased (SMD = -1.34; 95% CI (-1.88, -0.80); p < 0.00001). It was also reported that the patient's quality of life improved after treatment for a period of 4 weeks (SMD = -0.29; 95% CI (-0.42, -0.16); p < 0.0001) and after a follow-up of 1 month (SMD = -0.20; 95% CI (-0.34, -0.07); p=0.003). The evidence level of the results was determined to be very low to low. Conclusions: Based on the existing evidence, it can be concluded that TFM may have a better effect than other treatments on LBP. However, it is not yet possible to assess the safety level of TFM therapy. Due to the universal low quality of the eligible trials and low evidence level, rigorously designed large-scale RCTs must be conducted in order to further confirm the results in this review.

Gut microbial dysbiosis in rheumatoid arthritis: a systematic review protocol of case-control studies.

INTRODUCTION: Rheumatoid arthritis (RA) has a huge societal impact due to the high prevalence, irreversible joint damage and systemic complications. Gut microbiota plays an important role in the pathogenesis and progression of RA by regulating the host immune system. Restoring intestinal homeostasis by altering the microbiota could be an attractive strategy for the prevention and treatment of RA. However, the signature features of microbial dysbiosis in RA are still controversial. Therefore, we aim to elucidate the characteristic change in the diversity and composition of gut microbiota in RA. METHODS AND ANALYSIS: We will systematically search through PubMed, EMBASE, Web of Science and Cochrane Library, as well as dissertations and conference proceedings. The reference lists of all included studies will be also reviewed to retrieve additional relevant studies. The case-control studies that reported either the relative abundance of bacteria at the phylum or genus level or at least one of the alpha-diversity, beta-diversity indexes in both RA and healthy controls will be included. Eligible studies will be screened independently by two reviewers according to the inclusion criteria. The Newcastle-Ottawa Quality Assessment Scale will be used to assess the quality of the included studies. Data extraction, qualitative and quantitative analysis will be performed within the gut microbial dysbiosis in RA. The expected outcomes will be the identification of the specific changes in composition and diversity of the gut microbiota in patients with RA. The quality of evidence will be assessed by the Grading of Recommendations Assessment, Development and Evaluation framework. ETHICS AND DISSEMINATION: Ethical approval is unnecessary as this review does not address the data and privacy of patients. The results will be published in a peer-reviewed scientific journal and conference presentations. PROSPERO REGISTRATION NUMBER: CRD42021225229.

N-(2-Chloro-pyrimidin-4-yl)-2-methyl-2H-indazol-6-amine methanol monosolvate.

In the title compound, C(12)H(10)ClN(5)·CH(3)OH, the indazole ring system and the pyrimidine ring make a dihedral angle of 23.86 (4)°.

Inter-molecular π-π inter-actions [centroid-centroid distances = 3.6404 (9), 3.6725 (9) and 3.4566 (9) Å] between the rings of neighbouring chains also stabilize the crystal packing.

Retrospective Analysis of Clinical Characteristics and Neonatal Outcomes of Pregnant Women with SARS-COV-2 Infection.

This retrospective study aimed to investigate the clinical characteristics and neonatal outcomes of pregnant women with SARS-COV-2 in Wuhan Children's Hospital and further suggested a possible management strategy for infected pregnant women under epidemic situation. In this study, 8 pregnant women with SARS-COV-2 who were admitted into Wuhan Children's Hospital, China from February 1, 2020 to March 30, 2020 and the clinical features, laboratory data, maternal and neonatal outcomes were analyzed. The mean age of the women at the time of admission was 30.6 years. The mean gestational age of the women was 37 weeks+4 days, and one woman presented with dichorionic diamniotic (DCDA) twin pregnancy. Except for one woman who was febrile, others had no typical clinical symptoms. For all pregnant women, the count of white blood cells and lymphocytes appeared normal, but 6 had a lower percentage of lymphocytes. C-reactive protein (CRP) levels were normal for all the women. One neonate was tested positive for the coronavirus IgG and IgM antibodies. The clinical symptoms of the pregnant women with SARS-COV-2 were mild, and the laboratory data showed similar characteristics to those of non-infected pregnant women. Since one neonate was tested positive for coronavirus, there is a possibility of vertical transmission of SARS-CoV-2. Prompt and efficient screening, triage, and isolation of pregnant women are effective management strategies to reduce nosocomial infection during the SARS-COV-2 epidemic.

Electrodepositing a 3D porous rGO electrode for efficient hydrogel electrolyte integration towards 1.6 V flexible symmetric supercapacitors.

A reduced graphene oxide electrode with a three-dimensional porous structure is synthesized based on a facile electro-reduction strategy with subsequent freeze-drying. The 3D architecture enables the full penetration of the PVA-NaClO4 hydrogel electrolyte, giving rise to a 1.6 V quasi-solid-state symmetric supercapacitor with good flexibility, good temperature/pressure tolerance and high areal/volumetric energy and power densities.

Decrypting tubby-like protein gene family of multiple functions in starch root crop cassava.

Tubby-like proteins (TLPs) are ubiquitous in eukaryotes and function in abiotic stress tolerance of some plants. Cassava (Manihot esculenta Crantz) is a high-yield starch root crop and has a high tolerance to poor soil conditions and abiotic stress. However, little is known about TLP gene characteristics and their expression in cassava. We identified cassava TLP genes, MeTLPs, and further analysed structure, duplication, chromosome localization and collinearity, cis-acting elements in the promoter regions and expression patterns of MeTLPs, and three-dimensional structure of the encoded proteins MeTLPs. In conclusion, there is a MeTLP family containing 13 members, which are grouped into A and C subfamilies. There are 11 pairs of MeTLPs that show the duplication which took place between 10.11 and 126.69 million years ago. Two MeTLPs 6 and 9 likely originate from one gene in an ancestral species, may be common ancestors for other MeTLPs and would most likely not be eligible for ubiquitin-related protein degradation because their corresponding proteins (MeTLPs 6 and 9) have no the F-box domain in the N-terminus. MeTLPs feature differences in the number from TLPs in wheat, apple, Arabidopsis, poplar and maize, and are highlighted by segmental duplication but more importantly by the chromosomal collinearity with potato StTLPs. MeTLPs are at least related to abiotic stress tolerance in cassava. However, the subtle differences in function among MeTLPs are predictable partly because of their differential expression profiles, which are coupled with various cis­acting elements existing in the promoter regions depending on genes.

Molecular detection of uterine innate lymphoid cells in the immunological mouse model of pregnancy loss.

Innate lymphoid cells (ILCs) are newly identified members of the innate lymphocyte family, which can function as adaptive T cells and act as critical modulators of inflammatory processes within different tissues and immune diseases. The role of uterine ILCs (uILCs) has recently been elucidated alongside changes associated with normal pregnancy. However, the proportions of uterine ILCs and their role in unsuccessful pregnancy remain unclear. We analyzed the characterization of uILC subsets and the expression of signature cytokines associated with ILCs in a mouse model of unsuccessful pregnancy induced by LPS, and we describe the dynamic changes they undergo during this process. We found that mice exposed to LPS display significantly higher levels of uNK cells, and uILC3s. However, a lower proportion of uILC2s and uILC1s were detected in abortion mice. In addition, we found that abortion mice display markedly higher expression of IFN-γ and IL-A17, and lower levels of IL-5. No significant differences in the expression of IL-13 and IL-22 were observed. The findings suggest that uILCs play distinct non-redundant roles during pregnancy, and uILCs may affect maternal-fetal tolerance via IL-17A, IL-5, and IFN-γ production.

Overexpression of Tat-interacting protein 30 inhibits the proliferation, migration, invasion and promotes apoptosis in bladder cancer cells.

AIMS: Tat-interacting protein 30 (TIP30), a transcriptional repressor, possesses antitumor effect in different cancer cells. However, little is known about the function of TIP30 in bladder cancer till now. MATERIALS AND METHODS: A TIP30-overexpressing plasmid was transfected into the bladder cancer cells (T24). The cell cycle and apoptosis were detected by flow cytometry. The cell proliferation was analyzed using the cell counting kit-8 assay. The migrative and invasive abilities of T24 cells were measured by the transwell assay. The expression of TIP30, cell cycle proteins, migration-related proteins, and cell apoptosis-related proteins was assessed by Western blotting. RESULTS: The cell proliferation, migration, and invasion of T24 cells were inhibited by overexpression of TIP30. Moreover, the rate of cell apoptosis was increased by the overexpression of TIP30. The expression of cell cycle proteins, phosphorylated EGFR, p-Akt, Bcl-2, cyclin D, cyclin E), migration-related proteins (matrix metalloproteinases 2 [MMP2], MMP6, MMP9), were downregulated, and cell apoptosis-related proteins (bax, cleaved caspase3) were upregulated. CONCLUSIONS: These results suggest that TIP30, as a tumor suppressor in the bladder cancer, might be served as a target in cancer therapies in the future.

SATB1 promotes epithelial-mesenchymal transition and metastasis in prostate cancer.

Special AT-rich sequence-binding protein-1 (SATB1) is associated with cancer progression and poor clinical outcome. The present study aims to evaluate whether SATB1 affects the biological behaviors of prostate cancer (PCa), and furthermore, to elucidate whether this effect works through the epithelial-mesenchymal transition (EMT) pathway. Firstly, the expression of SATB1 was investigated in a series of PCa tissues as well as in a panel of PCa cell lines. Cell proliferation, migration and invasion were evaluated in SATB1 knockdown and overexpressed PCa cell lines by MTT and Transwell assays. The results showed that the expression of SATB1 was markedly upregulated in PCa tissues and all PCa cell lines (P<0.001). Ectopic expression of SATB1 promoted PCa cell proliferation and migration. Knockdown of SATB1 repressed the ability of cell proliferation and migration of PCa cells. In addition, inhibition of SATB1 could reverse the EMT processes through upregulation of E-cadherin and downregulation of vimentin. The present study provided evidence that SATB1 may act as a potential therapeutic target in PCa patients.

Cdc6 contributes to cisplatin-resistance by activation of ATR-Chk1 pathway in bladder cancer cells.

High activation of DNA damage response is implicated in cisplatin (CDDP) resistance which presents as a serious obstacle for bladder cancer treatment. Cdc6 plays an important role in the malignant progression of tumor. Here, we reported that Cdc6 expression is up-regulated in bladder cancer tissues and is positively correlated to high tumor grade. Cdc6 depletion can attenuate the malignant properties of bladder cancer cells, including DNA replication, migration and invasion. Furthermore, higher levels of chromatin-binding Cdc6 and ATR were detected in CDDP-resistant bladder cancer cells than in the parent bladder cancer cells. Intriguingly, down-regulation of Cdc6 can enhance sensitivity to CDDP both in bladder cancer cells and CDDP-resistant bladder cancer cells. Cdc6 depletion abrogates S phase arrest caused by CDDP, leading to aberrant mitosis by inactivating ATR-Chk1-Cdc25C pathway. Our results indicate that Cdc6 may be a promising target for overcoming CDDP resistance in bladder cancer.

Antibiotics are not beneficial in the management of category III prostatitis: a meta analysis.

PURPOSE: To determine whether antibiotics are beneficial in the management of category III prostatitis. MATERIALS AND METHODS: The PubMed, Medline and Embase databases were searched for all published documents from January 1, 1965 to September 1, 2012 without language restriction. The randomized controlled trials that mentioned comparable groups of antibiotics treatment versus placebo or other control group for patients with category III prostatitis were included based on specific criteria. The quality of studies was assessed by the modified Jadad scale, and Revman 5.0 software was used for data syntheses and analysis. RESULTS: Seven studies which met the selection criteria were included in this review. All of them were high quality according to the modified Jadad scale. A random effect model was applied because of the high heterogeneity. The meta-analysis showed that summary association between category III prostatitis and antibiotics were not statistically significant. CONCLUSION: Our meta-analysis reveals that antibiotics are not beneficial in the management of category III prostatitis. Therefore, we may reduce the usage of antibiotics in such a population.
