Central precocious puberty (CPP) without organic abnormality is called idiopathic CPP (ICPP). The objective of this trial was to evaluate the effects of pomegranate extract in supplementing gonadotropin-releasing hormone (GnRH) analog therapy on ICPP-affected girls in the Chinese population. 286 girls, diagnosed with ICPP were initially enrolled into this trial, and among them 225 eligible patients were randomized to receive a combinational GnRH analog treatment supplemented with either a placebo or pomegranate extract on a daily basis for a period of 3 months. Their demographics, secondary sexual characteristics and hormone profiles were analyzed at baseline and end of trial. After 3 months of treatment, demographic profiles including bone age, growth velocity and height standard deviation score for bone age, and secondary sexual characteristics including uterus and ovary volume, as well as serum hormone profiles including estradiol, peak luteinizing hormone and insulin-like growth factor 1 were all significantly improved in girls receiving a combinational treatment of both GnRH analog and pomegranate extract. Daily consumption of pomegranate extract was able to supplement and improve the treatment outcomes of the GnRH analog therapy for ICPP in Chinese girls. © The Royal Society of Chemistry.

Objective: The purpose of this study was to investigate the expression of Twist in salivary adenoid cystic carcinoma (SACC) and the relations between Twist expression and the clinicopathological characteristics. Methods: The expression of Twist was examined immunohistochemically in 48 cases of SACC, 18 of pleomorphic adenoma and 10 of normal parotid gland. The relationship between Twist expression in SACC and the clinicopathological factors was analyzed. Results: Twist expression was significantly higher in SACC tissues compared with pleomorphic adenomas and normal parotid gland tissues (P < 0.05). Twist expression levels in SACC were significantly associated with histological type, perineural invasion, postoperativerecurrence, and distant metastasis (P < 0.05), rather than age, gender, tumor site, tumor size, or clinical staging (P > 0.05). Conclusion: Twist expression may be associated with tumor cell differentiation, perineural invasion and metastasis of SACC. Twist expression is a potential prognostic factor for disease survival of SACC. © Springer-Verlag Berlin Heidelberg 2010.

Purpose: To assess the diagnostic efficacy of ultrasonography in detecting disc displacement of the temporomandibular joint. Materials and Methods: MEDLINE (using OVID, 1950 to April 2011), EMBASE (1980 to April 2011), and the Chinese Biomedical Literature Database (1978 to April 2011) were searched electronically. In addition, relevant journals and reference lists of the included studies were manually searched for any eligible studies on diagnostic accuracy. Two authors performed the study inclusion, data extraction, and risk of bias assessment in duplicate. Meta-analysis was performed with MetaDisc 1.4. Results: Fifteen studies were included in this meta-analysis; 6 studies had a low risk of bias, 6 studies an unclear risk, and 3 studies a high risk. Meta-regression indicated that the detected results were not influenced by the types of ultrasonography, image dimensions, types of transducer, and ultrasonic image of the disc (P >.05). The Q* values of ultrasonography for the closed- and open-mouth positions were 0.79 and 0.91, respectively. The diagnostic efficacy of disc displacement with reduction had a sensitivity of 0.76, a specificity of 0.82, a positive likelihood ratio of 3.80, a negative likelihood ratio of 0.36, a diagnostic odds ratio of 10.95, an area under the curve of 0.83, and a Q* of 0.76. The diagnostic efficacy of disc displacement without reduction had a sensitivity of 0.79, a specificity of 0.91, a positive likelihood ratio of 80.5, a negative likelihood ratio of 0.25, diagnostic odds ratio of 36.80, an area under the curve of 0.97, and a Q* of 0.92. Conclusions: The diagnostic efficacy of ultrasonography is acceptable and can be used as a rapid preliminary diagnostic method to exclude some clinical suspicions. However, positive ultrasonographic findings should be confirmed by magnetic resonance imaging. Also, the ability of ultrasonography to detect lateral and posterior displacements is still unclear. More high-quality studies are needed to assess the diagnostic efficacies of some specific ultrasonographic methods. Standards and criteria for ultrasonographic techniques in the diagnosis of disc displacement should be established in the future.

The pineal hormone, melatonin (MLT), has been shown to have therapeutic effects in patients with gastric cancer; however, the mechanisms for the anti-cancer effects are unknown. We investigated the effects of melatonin on cell proliferation, apoptosis, colony formation and cell migration in the gastric adenocarcinoma cell line, SGC7901, using MTT assay, Hoechst 33258 staining, flow cytometry, western blot, caspase-3 activity assay, soft agar colony formation assay, and scratch-wound assay. Our results showed that melatonin could inhibit cell proliferation, colony formation and migration efficiency, and it promoted apoptosis of SGC7901 cells. Our findings suggest that the anti-cancer effects of melatonin may be due to both inhibition of tumor cell proliferation and reduction of the metastatic potential of tumor cells. © 2013 The Biological Stain Commission.

The vitamin D receptor (VDR) is a crucial mediator for the cellular effects of vitamin D. A great number of studies regarding the association between BsmI polymorphism in the VDR gene and breast cancer have been published. However, the results have been contradicting. Therefore, we conducted a meta-analysis to re-examine the controversy. Published literatures from PubMed, Embase, and Chinese Biomedical Literature Database (CBM) were searched (updated to July 10, 2013). The principal outcome measure was the odds ratio (OR) with 95 % confidence interval (CI) for breast cancer risk associated with VDR BsmI polymorphism. With all studies involved, the meta-analysis results suggest no statistically significant association between VDR BsmI polymorphism and breast cancer risk (B vs. b, OR = 0.922, 95 % CI = 0.836-1.018, P = 0.108, I 2 = 80.0 %; BB vs. bb, OR = 0.843, 95 % CI = 0.697-1.021, P = 1.75, I 2 = 75.5 %; Bb vs. bb, OR = 0.930, 95 % CI = 0.814-1.063, P = 0.31, I 2 = 73.1 %; BB+Bb vs. bb, OR = 0.906, 95 % CI = 0.787-1.043, P = 1.37, I 2 = 78.7 %; BB vs. bb+Bb, OR = 0.899, 95 % CI = 0.786-1.028, P = 1.56, I 2 = 61.0 %). The results were not changed when studies were stratified by ethnicity or source of controls. This meta-analysis suggested that there were no associations between VDR BsmI polymorphism and breast cancer. © 2013 The Author(s).

A hallmark of cancer is resistance to apoptosis, with both the loss of proapoptotic signals and the gain of anti-apoptotic mechanisms contributing to tumorigenesis. As inducing apoptosis in malignant cells is one of the most challenging tasks regarding cancer, researchers increasingly focus on natural products to regulate apoptotic signaling pathways. Curcumin, a polyphenolic derivative of turmeric, is a natural compound derived from Curcuma longa, has attracted great interest in the research of cancer during the last half century. Extensive studies revealed that curcumin has chemopreventive properties, which are mainly due to its ability to arrest cell cycle and to induce apoptosis in cancer cells either alone or in combination with chemotherapeutic agents or radiation. The underlying action mechanisms of curcumin are diverse and has not been elucidated so far. By regulating multiple important cellular signalling pathways including NF-κB, TRAIL, PI3 K/Akt, JAK/STAT, Notch-1, JNK, etc., curcumin are known to activate cell death signals and induce apoptosis in pre-cancerous or cancer cells without affecting normal cells, thereby inhibiting tumor progression. Several phase I and phase II clinical trials indicate that curcumin is quite safe and may exhibit therapeutic efficacy. This article reviews the main effects of curcumin on the different apoptotic signaling pathways involved in curcumin induced apoptosis in cancer cells via cellular transduction pathways and provides an in depth assessment of its pharmacological activity in the management of tumor progression. © 2014 Springer Science+Business Media.

Diabetic nephropathy (DN) is a major cause of morbidity and mortality in diabetic patients. Effective therapies to prevent the development of this disease and to improve advanced kidney injury are required. Berberine (BBR) has preventive effects on diabetes and its complications. This study is to investigate the effects of BBR on the expression of E-prostanoid receptors (EPs) in rats with high-fat diet and streptozotocin (STZ)-induced DN and underlying molecular mechanisms of BBR on DN rats. DN model was induced in male Sprague - Dawley rats with high-fat diet and low dose of STZ injection. BBR (50, 100, 200 mg/kg/d) were orally administered to rats after STZ injection and conducted for 8 weeks. The levels of interleukin-6 (IL-6) and prostaglandin E2 (PGE2) in renal cortex were measured by enzyme-linked immunosorbent assay. Expression of EPs receptors (EP1 - EP4) were determined by western blotting. Remarkable renal damage, hyperglycemia and hyperlipidemia were observed in DN rats. BBR could restore renal functional parameters, suppress alterations in histological and ultrastructural changes in the kidney tissues, improve glucose and lipid metabolism disorders, and increase cAMP levels compared with those of DN model group (Wang et al. in Mol Biol Rep 40:2405-2418, 2013). The level of IL-6 and PGE2 were significantly increased in DN model group compared with normal group, BBR could apparently reduced the level of IL-6 and PGE2. Furthermore, the expression of EP1 and EP3 were both increased and EP4 was lessened in the DN model group compared with normal group, BBR could down-regulate total protein expression of EP1 and EP3 of renal cortex in DN rats and up-regulate the expression of EP4, and there is no significant difference on the expression of EP2 among all groups. These studies demonstrate, for the first time, that BBR exerts renoprotection in high-fat diet and STZ-induced DN rats by modulating the proteins expression of EPs in EP - G protein - cAMP signaling pathway. © Springer Science+Business Media 2014.

This article provides an overview of metastases to jaws (MJ), mainly concerning the differences between American and Chinese patients, and exploring the relationship between the primary tumors' prevalence (PTP) and constituent ratio of MJ. Information concerning of 399 MJ cases in 215 papers, including one new case in our hospital, was subjected to statistic analysis. The main clinical features of MJ, such as constituent ratio of PTP and that of MJ, metastatic sites, treatments, and prognosis were summarized. Breast, lung, kidney, prostate and thyroid (in descending order) were the leading primary sites of MJ. Furthermore, the constituent ratio of MJ was found to be correlated with that of PTP in all subjects including American and Chinese subjects in our study. As to metastatic sites in the mandible, a specific "M" shaped pattern appeared regardless of the tumor type or constituent ratios of MJ were in all subjects. Almost all subjects received traditionally palliative treatments, and the prognosis was quite poor. The PTP had a significant impact on the constituent ratio of MJ. However, it was the properties of the microenvironment rather than characteristics or constituent ratios of tumor cells, that decided the metastatic sites in various tumor subjects.

OBJECTIVE: This study aimed to investigate the levels of matrix metalloproteinas-es (MMP)-2, MMP-9 and Twist in tumor tissue and serum from 46 cases of breast cancer patients and 31 cases of benign breast diseases patients by immunohistochemical staining and enzyme-linked immunosorbent assay, respectively. The association of gelatinase and Twist expression with clinicopathological factors was also analyzed in the present study. PATIENTS AND METHODS: The studied population consisted of 46 breast cancer patients and 31 benign breast disease patients. Serum concentrations of MMP-2, MMP-9 and Twist were measured by using human enzyme-linked im-munosorbent assay. The protein expression of Twist, MMP-2 and MMP-9 were determined by im-munohistochemical. RESULTS: The results show that the levels of MMP-2, MMP-9 and Twist expression were significantly increased in tissue and serum from breast cancer group, compared to the group of benign breast lesions diseases (p < 0.05). The pre-operative serum levels of MMP-2, MMP-9 and Twist were positively correlated with their expression in breast cancer tissues, respectively (p < 0.05). We, then, correlated serum and tissue levels of MMP-2, MMP-9 and Twist in breast cancer samples with patients' clinico-pathologic characteristics. Compared to low expression, high serum and tissue levels of MMP-2 and Twist were associated with lymph node metastasis and higher TNM stage, high tissue MMP-9 levels were associated with lymph node metastasis and higher TNM stage, and high serum MMP-9 levels were associated with c-erbB-2 expression. CONCLUSIONS: These data suggest that serum levels of MMP-2, MMP-9 and Twist could be as potential biomarkers for diagnosis and predicting metastasis of breast cancer.

Objective: To investigate whether circulating cell-free (cf)-DNA levels are a useful biomarker for survival in patients with shock in the emergency intensive care unit (EICU). Methods: This prospective observational study enrolled patients admitted to the EICU diagnosed with shock. Blood cf-DNA levels were analysed on admission, and after 24 and 48 h. As a measure of circulating cf-DNA, copy number of the β-globin gene in plasma was assessed using quantitative real-time polymerase chain reaction. Results: Circulating cf-DNA levels were higher at hospital admission and after 24 h in EICU patients with shock who died than in those who recovered. Change in cf-DNA levels over the first 48 h in critical care was independently associated with 28-day mortality. The critical cut-off value for cf-DNA change over 48 h in predicting 28-day mortality was +16.12% (sensitivity 68.9%, specificity 89.7%). Conclusions: Increased circulating cf-DNA levels in EICU patients with shock are associated with risk of death and measuring cf-DNA change over 48 h improves risk prediction. The present study suggests that cf-DNA may serve as a viable plasma biomarker of mortality risk in EICU patients with shock. © 2016, © The Author(s) 2016.
