Concealed penis is usually found in children, which affects the patients both physiologically and psychologically. Some of the patients are wrongly treated by circumcision, which may bring about serious consequences to the sexual life of the patients in their adulthood. In the recent years, this disease has been receiving more and more attention from both doctors and parents. However, controversies remain as to its classification, pathogenesis, pathology, and treatment. This paper focuses on the understanding and advances in the studies of concealed penis.

To study the effects of alkaloids from Coptidis Rhizoma on low-density lipoprotein receptor (LDLR) mRNA expression and antihyperlipedemic levels. The LDLR mRNA expression were detected by real time fluorescence quantitative PCR, and the levels of total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL-c) and high-density lipoprotein cholesterol (HDL-c) in serum were measured at the first and last examination. The results show that, after the drug treatment, compared with the model group, each drug group showed a lipid-lowering effect. Especially, coptisine, palmatine, jatrorrhinze were significantly reduced TC, TG, LDL-c (P < 0.05, P < 0.01), and increased HDL-c (P < 0.01). In addition, they also increased mRNA expression of the LDLR in liver and HepG2 cells. The results showed that alkaloids from Coptidis Rhizoma can regulate lipid metabolism disorder, and coptisine have the best lipid-lowering effect.

Cell-penetrating peptides (CPPs) offer a non-selective and receptor-independent mode to promote cellular uptake. Although the non-specificity of CPP-mediated internalization allows this approach applicable to a wide range of tumor types potentially, their universality is a significant obstacle to their clinical utility for targeted delivery of cancer therapeutics and imaging agents. Accordingly, many reports have focused on selective switching of systemically delivered inert CPPs into their active form in lesions (tumor). In this review, our attention is mainly confined to such an enzyme-sensitive domain incorporated delivery system with activatable CPPs (ACPPs), which have displayed the exciting strength in balancing the CPPs' pros and cons, and potential in the treatment and diagnosis of some diseases.

Chronic prostatitis (CP) is a common disease in men, and its pathogenesis remains to be clarified. The precise regulation of cytokines is involved in all types and all stages of CP. The interaction of inflammation, inflammatory cells and cytokines leads to the development and progression of CP. With further understanding of the immunological and molecular biological mechanisms of the disease and more inflammatory cytokines used in its detection, it is of special significance to apply cytokines in the classification and treatment of CP. This review outlines the roles of cytokines in the pathogenesis of CP, particularly chronic pelvic pain syndrome (CPPS), their relationship with CP, and their significance in the classification and diagnosis of CP/CPPS.

The present study identified the favorable environment conditions for Spermatogomial stem cells in vitro according to their unique biological properties. Three growth factors, stem cell factor (SCF), leukemia inhibitory factor (LIF) and basic fibroblast growth factor (bFGF) were all found to independently contribute to the proliferation of mouse spermatogonial stem cell. The percentage of cell proliferation significantly enhanced by SCF at 30 ng/mL but decreased with heightening its combination after cultured 120 hours. The mice spermatogonial stem cells were significantly proliferated after 120 hours' culture with 10 ng/mL and 20 ng/mL (P < 0.01) of LIF, between 20 ng/mL and 50 ng/mL (P < 0.01) for bFGF. SCF and bFGF were significantly enhanced mice spermatogonial stem cells proliferation after these three factors combination. For LIF, no obvious effect was observed.

Objective To explore the application of B-mode intra- and post-operative ultrasound in patients with traumatic brain injuries. Methods B-mode intra- and post-operative ultrasound were performed 35 times in 24 patients, including 7 times of intra-operation in 7 patients and 28 times of post-operation in 17 patients. Results During operation epidural hematomas in 3 cases as well as intracranial hematomas in 2 cases, subdural hematomas in 1 case, diffused brain swelling in 1 case were found. After operation epidural hematomas were examined in 4 cases as well as subdural hematomas in 1 case, delayed intracranial hematomas in 6 cases, scattered contusion and laceration of the brain in 12 cases, acute obstructive hydrocephalus in 1 case, and subdural hydroma in 4 cases. Six cases underwent operations again because of delayed hematomas, contusion and laceration of the brain. B-mode ultrasound was compared with CT scan and the total coincidence rate was 85.4%.Conclusions B-mode ultrasound is helpful to examine delayed hematomas and other emergent complications. It may save time and may improve rescue rate and has a good coincidence with CT scan. B-mode ultrasound may be widely used as a routine way in neurotrauma ICU.

Objective To investigate the distribution of high-arsenic drinking water in Honghu city of Hubei province in order to provide a scientific basis for prevention and control of endemic arsenic disease.Methods Investigations were made in 22 townships(towns,districts),68 natural villages of the drainage areas of the Dongjing River,the Neijing River and the Yangtse River in 2006 and 2007,with the townships(towns,districts)around Shahu town in Xiantao city as the focal point.1000 water samples were drawn each year,which was 10% of all the wells in every natural village.Using sampling investigation,water arsenic Was determined by half-quantitative fast reagent kit.All samples of water with arsenic exceeding the standard(≥0.03 mg/L)were re-determined according to state standard.Surveys on the disease was carried out in the villages(brigades)where arsenic exceeded the standard.Results A total of 2000 samples were surveyed from 68 natural villages,of which there were 401 samples from 48 villages exceeding the standard in a rate of 20.05%(401/2000).The highest arsenic content Was 0.71 mg/L.The high arsenic water sources were distributed mainy in the drainage areas of the Dongjing River and the Neijing River,but no patients with endemic arsenic disease were found.Conclusions The high arsenic water sources are distributed mainly in the drainage areas of the Dongjing River and the Neijing River.It is suggested that the interrelated government departments should take precise measures to impmve the quality of drinking water and ensure safe water to the residents in high arsenic areas.

Objective To investigate the effect of recombinant adenovirus mediatied human endostatin (rAD-GFP-ES)on rats with collagen typeⅡinduced arthritis(CIA),and explore the mechanism of inflamma- tion and cytokines inhibition on rats CIA.Methods The rAD-GFP-ES was amplified and purified.The model of rat CIA was induced by intradermal injection of typeⅡcollagen combined with complete Freund's adjuvant(CFA). On the second day after the injection,the therapeutic administration of rAD-GFP-ES(1?10~(11)pfu?kg~(-1)?week~(-1)?4 weeks)were performed to the rats.The mean arthritis index(AI)was scored every week since then.The relative concentrations of ES,IL-I?,TNF-?in sera collected at the fourth week were evaluated by western blotting. Results①The titer of the purified rAD-GFP-ES and rAD-GFP was 6.6?10~(12)pfu/ml and 4.8?10~(12)pfu/ml,re- spectively(A_(260nm)/A_(280nm)＞1.3).②The concentration of ES in sera of the group treated with rAD-GFP-ES was 2.4-lold higher compared to the normal group.③The mean arthritis index of the group treated with rAD-GFP- ES was much lower than that of the model group.The administration of rAD-GFP-ES could significantly de- creas the production of IL-1?and TNF-?in sera.Conclusions①The rAD-GFP-ES is efficiently expressed in vivo.②The rAD-GFP-ES has an inhibitory effect on the arthritis index of rat CIA.③IL-1?and TNF-?are involved in the pathogenesis of RA.The rAD-GFP-ES has an inhibitory effect on the expression of IL-1?and TNF-?in rat CIA.
