The three-dimensional organization and anastomoses of lymphatics in the rabbit stomach were demonstrated by scanning electron microscopy of lymphatic corrosion casts. Casting medium is the diluted low viscosity Mercox used for intraparenchymatous injection into the mucosal, submucosal, muscular and serous layers of the stomach. The lymphatic capillaries with blind ends were found in the deep mucosa and the lymphatic capillary networks and lymphatic plexus were observed in all the submucosal, muscular and serous layers. The distinct imprints which correspond to the bicuspid valves of lymphatics and the oval or fusiform impressions of the endothelial nuclei were seen on the casts.

By using 5'-nucleotidase-alkaline phosphatase (5'-Nase-AlPase) double staining method, the fine distribution of the lymph vessels in the stomach wall of the rabbit, guinea pig and rat has been observed. Under light microscope lymph capillaries showed strongly 5'-Nase positive reaction with brown or dark brown staining. However blood capillaries revealed significantly A1Pase activity with blue staining. The lymph capillaries were seen in all layers of the stomach wall in three species, but the lymph vessels were only shown in the submucosa, muscularis and serosa. In the mucosa lymph capillaries could be found in the deep layer of the lamina propria. In the submucosa there were lymph vessels and capillaries. In the muscularis lymph capillaries and vessels not only could be found between oblique and circular muscle or between circular and longitudinal muscle, but also among muscle fiber bundles of each layer. In the serosa there were larger lymph vessels situated near the muscularis. The observation on semithin and ultrathin sections also shown the similarity in the lymph vessels distribution. There was no difference in the distribution of lymph vessels in the stomach wall between rabbit, guinea pig and rat.

ObjectiveTo observe clinical therapeutic effect of scalp acupuncture combined with traditional body acupuncture on pseudobulbar palsy induced by ischemic or hemorrhagic apoplexy.Methods59 inpatients with pseudobulbar palsy induced by stroke were divided into the scalp acupuncture combined with body acupuncture group (n=40) and body acupuncture group (n=19). Cases of the scalp acupuncture combined with body acupuncture group were treated by scalp acupuncture combined with traditional body acupuncture. Cases of the body acupuncture group were treated only by traditional body acupuncture. Therapeutic effect of two groups was assessed according to patients' consciousness, language and limb functions.ResultsIn the scalp acupuncture combined with body acupuncture group, 30 cases were cured and 9 were remarkably effective, with a total effective rate of 97.5%. While in the body acupuncture group, 9 cases were cured, and 7 were remarkably effective, with a total effective rate of 84.2%. There was a significant difference between two groups in clinical cure rate (P<0.05), but no difference in total effective rate ( P>0.05).ConclusionScalp acupuncture combined with traditional body acupuncture can obviously improve the consciousness, language and limb functions and pseudobulbar palsy of stroke patients and obtain a better effect compared with traditional body acupuncture.

Objective: To study the correlation between expression of oncogene C-MYC protein and gene abnormality in diffuse large B-cell lymphoma (DLBCL). Methods: The expression of C-MYC protein and gene abnormality were detected by immunohistochemistry and fluorescence in situ hybridization (FISH), respectively, in 42 cases of paraffin-embedded DLBCL. All cases were collected at Department of Pathology, Weifang People′s Hospital during January 2015 to October 2016. Results: The positive rate of C-MYC protein expression was 47.6% (20/42) and the rate of abnormal C-MYC gene by FISH was 26.2%(11/42), including translocation (23.8%, 10/42) and gene amplification (2.4%, 1/42). There was a close relationship between the protein expression and gene translocation (χ²=11.813; P=0.001) and gene translocation occurred primarily in GCB (χ²=4.029; P=0.045). Conclusion The high expression (≥40%) of C-MYC protein is associated with its gene translocation, suggesting that C-MYC protein detection can be used as a surrogate marker for C-MYC gene translocation in DLBCL.

Osteoporosis （OP） is a systemic metabolic bone disease characterized by bone microstructure degeneration and bone mass loss， which has a high prevalence and disability rate. Effective prevention and treatment of OP is a major difficulty in the medical community. The nature of OP is that multiple pathological factors lead to the imbalance of human bone homeostasis maintained by osteoblasts and osteoclasts. Ferroptosis is a non-apoptotic cell death pathway， and its fundamental cause is cell damage caused by iron accumulation and lipid peroxidation. Studies have shown that ferroptosis is involved in and affects the occurrence and development of OP， which leads to OP by mediating the imbalance of bone homeostasis. Ferroptosis is an adjustable form of programmed cell death. The intervention of ferroptosis can regulate the damage degree and death process of osteoblasts and osteoclasts， which is beneficial to maintain bone homeostasis， slow down the development process of OP， improve the clinical symptoms of patients， reduce the risk of disability， and improve their quality of life. However， there are few studies on ferroptosis in OP. Traditional Chinese medicine （TCM） is a medical treasure with unique characteristics and great application value in China. It has been widely used in China and has a long history. It has the multi-target and multi-pathway advantages in the treatment of OP， with high safety， few toxic and side effects， and low treatment cost， and has a significant effect in clinical application. The intervention of TCM in ferroptosis to regulate bone homeostasis may be a new direction for the prevention and treatment of OP in the future. This article summarized the regulatory mechanisms related to ferroptosis， discussed the role of ferroptosis in bone homeostasis， and reviewed the current status and progress of active ingredients in TCM compounds and monomers in the regulation of OP through ferroptosis， so as to provide a theoretical basis for the participation of TCM in the prevention and treatment of OP in the future.
