The structure, karyotype and behavior of synaptonemal complex (SC) in the spermatocytes of hedgehog (Erinaceus euroaaus dealbatus (insectivora)) were analyzed by light and electron microscopy with a modified surface spread preparation which involves the use of sodium dodecyl-sulphate (SDS) and silver staining. The lateral elements of the synaptonemal complex have a constant width of about 50 nm, the distance between the two lateral elements is about 100 nm. The relative length and arm rationale constant for each autosomal SC. The relative length and arm ratio constant for ea of the autosomal SCs are very similar to that of mitotic autosome.The X and Y chromosome axes have a clear morphological distinction from the autosomal SC. The axes of X and Y chromosome pair and form a SC of certain length at pachytene stage. The axes of unpaired X and Y chromosome are heteropycnotic and display various morphological complexities. But these differentiations in hedgehog are primary than in other mammalians, such as human and mice. At pachytene stage the X and Y chromosome display an extensive side-by-side pairing segment with decreasing length as meiotic prophase progressed.

BACKGROUND: Several studies have demonstrated that bone marrow mcscnchymal stem cells (MSCs) can differentiate into osteoblasts after induction of bone morphogenetic protein (BMP).OBJECTIVE: This study was designed to compare the osteogenetic effects between MSCs, bBMP, and fibrin gel alone and their composite.DESIGN: A controlled observation experiment.SETTING: Second People's Hospital of Guangdong Province and Second Hospital Affiliated to Sun Yat-sen University.MATERIALS: This study was performed at the Second Hospital Affiliated to Sun Yat-sen University between January 2004 and June 2006. Healthy New Zealand rabbits were provided by the Laboratory Animal Center, Sun Yat-sen University.METHODS: Bone marrow was taken from the lilac bone. By density gradient centrifugation, autologous MSCs were in vitro cultured and amplified. A composite was made of fibrin gel and bovine bone morphogenetic protein (bBMP). After adding MSCs, another composite was made. Twelve rabbits underwent lumbar L3/4, LA/5, and LS/6 discectomy and interbody fusion via an anterior retroperitoneal approach. Three fusion sites in each animal were randomly assigned into three of four treatments: composite of MSCs and hBMP and fibrin gel (group A), composite of MSCs and fibrin gel (group B), composite of bBMP and fibrin gel (group C) and fibrin gel alone (group D). The interbodies were observed radiologically and histologically 3 months after surgery.MAIN OUTCOME MEASURES: Bone formation in the spinal interveRebral space of rabbits.RESULTS: Twelve weeks after surgery, bone formation was appasenfly greater in the Group A than in the other groups.Histological findings revealed continuous bone formation. The groups B and C showed equivalent radiological and histological changes. Bone formation was intermittent. Group D had fibrous union, but no bone formation. No residual fibrin gel was found in all groups, but a small amount of residual nucleus gelatinosus with a little cartilaginous tissue was visible in the intervertebral disc.X-ray examination results did not reveal vertebral posterior hyperplasia or spinal stenosis. There was significant difference in range of lumbar motion between the group B and the groups C and D (P < 0.05). No pronounced difference in vertebral posterior height loss existed among the groups.CONCLUSION: The composite of MSCs, fibrin gel and bBMP can promote bone regeneration and achieve osseous spinal fusion.

Sepsis and septic shock have high morbidity and mortality. The key point is that huge amount of nitric oxide (NO) is releasing into circulation, inducing marked dilation of blood vessels, and continuously decreased of blood pressure. The central link is inflammation and oxidative stress. Methylene blue can effectively inhibit NO, remove excessive NO and block the signal transduction pathway named inducible nitric oxide synthase-NO-soluble guanylate cyclase-cyclic guanosine monophosphate (iNOS-NO-sGC-cGMP). Meanwhile, it also play a role in inhibiting oxidative stress and inflammation. This paper reviews the mechanism of methylene blue in the treatment of sepsis and septic shock, as well as its treatment time window, optimal dose, administration mode and potential adverse reactions, to provide new ideas for clinical treatment.

ObjectiveBased on the theory of "gut-prostate" axis, this study explored the effects and mechanisms of Zishen Tongguan formula and Cinnamomi Cortex in the formula in treating rats with chronic non-bacterial prostatitis(CNP) by detecting the levels of inflammatory factors, and the composition and structure of intestinal flora in CNP rats. MethodsEight out of 42 SD rats were randomly selected as the normal group, and the remaining rats were injected with carrageenan to prepare the CNP model. After successful modeling, 32 rats were randomly divided into the model group, Ningmitai capsule group(0.50 g·kg-1), Zishen Tongguan formula group(2.00 g·kg-1), and the Phellodendri Chinensis Cortex-Anemarrhenae Rhizoma pair group(PCC-AR group, 2.00 g·kg-1), with 8 rats in each group. The administered groups were given the corresponding medicinal solution by gavage, and the normal and model groups were intragastrically administered with an equal volume of normal saline, once a day for 14 consecutive days. The prostate tissues of rats were collected and subjected to hematoxylin-eosin(HE) staining and Masson staining to observe the pathological changes of the tissues in each group. Enzyme-linked immunosorbent assay(ELISA) was used to detect the levels of related inflammatory factors in rat serum, and 16S rDNA sequencing was used to analyze the abundance and diversity changes of gut microbiota before and after administration, and species difference analysis was performed. ResultsAll the administered groups could alleviate the inflammatory symptoms of CNP rats, increase the expression levels of anti-inflammatory factors and decrease the expression levels of pro-inflammatory factors, with the most sIgnificant effect observed in the Zishen Tongguan formula group. Compared with the normal group, the expression levels of interleukin(IL)-8, hypersensitive C-reactive protein(hs-CRP), immunoglobulin(Ig)M, secretory IgA (sIgA), and inducible nitric oxide synthase(iNOS) were sIgnificantly increased in the model group(P<0.01). Compared with the model group, the expression levels of the above inflammatory factors in all administered groups were significantly reduced(P<0.01). When compared with the PCC-AR group, the Zishen Tongguan formula group showed a significant decrease in transforming growth factor(TGF)-β1 expression level(P<0.05) and a significant increase in IgM expression level(P<0.01). The results of gut microbiota analysis showed that, compared with the PCC-AR group, at the order level, the Zishen Tongguan formula group significantly reduced the relative abundance of conditional pathogens such as Bacteroidales, Acidaminococcales, Rhodospirillales, Clostridiales, and Elusimicrobiales(P<0.01). And at the genus level, the Zishen Tongguan formula group significantly decreased the relative abundance of pathogenic microbiota such as Lachnospira and Bacteroides(P<0.01) and significantly increased the relative abundances of beneficial microbiota such as Ruminococcus and Lactobacillus(P<0.01). ConclusionZishen Tongguan formula can reduce the level of harmful intestinal bacteria, increase the level of beneficial intestinal bacteria, down-regulate the expression of serum inflammatory factors, and the small amount of Cinnamomi Cortex in the formula may play a key role in the treatment of CNP with this formula.
