Objective To evaluate the efficiency of normal sacral nerve root transposition in repair of the sacral plexus root avulsion. Methods A total of 30 adult SD rats were chosen and divided into three groups,ie,group A(the sciatic nerve received no repair),group B(the autologous sacral plexus root nerve was bridged with the right L6 nerve root by the translocation of the left L6)and group C (the right L5 nerve root nerve was bridged by the translocation of the left L6),10 rats per group.The left side of the rats was used as the control side and the right one as the experimental side.Twelve weeks after operation,the rats in each group were selected for the histomorphological observation of the nerves under the microscope and the electron microscope.The models were evaluated by observing the survival rates of the rats,BBB scores,electron microscope weight and muscle fiber CSA(cross section area)of double biceps femoris,triceps surae and tibial muscle. Results Twelve weeks after operation,the BBB scores in groups B and C was higher than that in group A,with statistical difference(P<0.01)between three groups.A remarkable improvement was found in the ratio of weight and muscle fiber CSA of double biceps femoris,triceps surse and tibial muscle.The repair efficiency in the group C was better than that in the group B.In the group B,the biceps femoris,triceps surae and tibial muscle recovered at different degrees.The biceps femoris recovered the best,when a great deal of myelinated nerve fiber regeneration was observed under the microscope and the electromicroscope.Electromyography revealed the volatility in the muscles of three groups,with larger peak value for the proximal biceps femoris and the triceps muscle but smaller peak value for the distal anterior tibial muscle. Conclusions L6 transposition combined with auto-graft of nerve root or without the auto-graft can reconstruct the partial function of the sciatic nerve in the paraplegia rats,when the latter has the better effect.

Objective To investigate the effects of mannan-binding lectin (MBL) on IL-8 and TNF-α production induced by Candida albicans ( C. albicans) in human THP1/CD14 monocytes. Methods The THP1/CD14 cells were stimulated for 24 h with heat-inactivated yeast form or hyphal form cells of C. albicans strain at the indicated ratios after pretreated with human natural MBL at concentrations ranging from 1 to 20 mg/L for 2 h. The content of IL-8 and TNF-α in culture supernatants were detected by ELISA,and the levels of IL-8 and TNF-α mRNA expressions in these cells were determined by RT-PCR. Western blot was used to detect C. albicans-induced NF-κB translocation in THP1/CDI4 cells. Results ELISA showed that secretion of IL-8 and TNF-α from THP1/CD14 cells could be induced by both yeast cells and hyphal cells. Hyphal cells proved to be much less efficient than yeast cells in stimulating production of IL-8and TNF-α by THP1/CD14 cells. The productions of IL-8 and TNF-α by THP1/CD14 cells induced with C.albicans were profoundly inhibited by MBL at higher concentrations ( 10-20 mg/L) but not MBL at lower concentrations ( 1 mg/L). RT-PCR analysis also indicated that the mRNA expressions of IL-8 and TNF-αt in THP1/CD14 cells were decreased to various extents by MBL at higher concentration, compared to the corresponding THP1/CD14 cells stimulated with C. albicans only. Similarly, MBL at higher concentration ( 20mg/L) decreased the NF-κB translocation in THP1/CD14 cells. Conclusion MBL may inhibit IL-8 and TNF-α production induced by dimorphism C. albicans in THP1/CD14 cells, suggesting that MBL can play some roles on the regulation of C. albicans immune response.

Objective To investigate the effects of mannan-binding lectin(MBL) on TNF-α production induced by peptidoglycan (PGN) and its mechanism in human THP-1/CD14 monocytes.Methods The THP-1/CD14 cells were stimulated for 24 h with PGN at the indicated ratios after pretreated with human natural MBL at concentrations ranging from 1 to 20 mg/L for 2 h.The content of TNF-α and IL-6 in culture supernatants were detected by ELISA,and the levels of TNF-α and IL-6 mRNA expressions in these cells were determined by RT-PCR.FACS was used to investigate the interaction of MBL with THP-1/CD14 cells and the impact of MBL on PGN binding to THP-1/CD14 cells.Western blot was used to detect PGN-induced NF-κB translocation in THP-1/CD14 cells.Results ELISA showed that secretion of TNF-α and IL-6 from THP-1/CD14 cells could be induced by PGN ;The productions of TNF-α and IL-6 by THP-1/CD14 cells induced with PGN were profoundly inhibited by MBL at higher concentrations (10-20 mg/L) but not MBL at lower concentrations (1 mg/L).RT-PCR analysis also indicated that the mRNA expressions of TNF-α and IL-6 in THP-1/CD14 cells were decreased by MBL at higher concentration,compared to the corresponding THP-1/CD14 cells stimulated with PGN only.FACS showed that the binding of MBL to THP-1/CD14 cells was evident in a Ca2+-dependent manner.PGN could competitively inhibit the binding of MBL to THP-1/CD14 cells.MBL could competitively inhibit the binding of PGN to THP-1/CD14 cells by binding to THP-1/CD14 cells directly.Similarly,MBL at higher concentration (20 mg/L) decreased the NF-κB translocation in THP-1/CD14 cells.Conclusion MBL may inhibit TNF-α and IL-6 production induced by PGN in THP-1/CD14 cells through NF-κB signaling pathways,suggesting that MBL can play some roles in the regulation of PGN-induced inflammatory response.

Male lower urinary tract symptoms is a collective term for a group of symptoms associated with lower urinary tract disorders characterized by frequent urination, urgent urination, and difficulty of urination, of which the common causes are benign prostatic hyperplasia or overactive bladder. With the aging of the global population, the incidence of male lower urinary tract symptoms is increasing year by year. Based on the theoretical connotation of " zang-fu extraordinary connection", the relationship between the lungs and the bladder, the spleen and the small intestine, and the kidneys and the sanjiao with the formation of male lower urinary tract symptoms is explained from three perspectives. It is believed that lung qi depression and closure, disturbance of qi transformation in bladder, and insufficient spleen transport occur, the small intestine is dysfunctional, kidney yang is exhausted, and obstruction of the sanjiao waterway are the basic pathogenesis of male lower urinary tract symptoms. It is emphasized that the location of the disease should be identified. If it is related to the lungs and the bladder, then the disease should be treated by lifting the pot to lift the lid and diffusing the lung qi to benefit the bladder with Wuling Powder plus perilla leaf and bitter apricot seed; if it is related to the spleen and the small intestines, then the disease should be treated by raising the clear and directing the turbid downward and improving the spleen qi in order to support the small intestines with Shenling Baizhu Powder; if it is related to the kidneys and the sanjiao, then the disease should be treated by seeking the yang within the yin and warming and tonifying the kidney qi in order to dredge up the sanjiao with Bawei Shenqi Pill. According to the patient's condition, treatment can be combined with acupuncture, exercise, and other therapies. This paper can provide reference for clinical treatment of male lower urinary tract symptoms.
