In three isolated organs, spleen, cardiac and skeletal muscles, kinetic studies of red cell washout were carried out by using perfusion of the cell-free, oxygenated Ringer's solution. It is found that in each organ there are slow components for red cells to be emptied out from the vascular lumens ranging 30 to 50 minutes as the desaturation half-time. The slowest decay constants (K) are -1.48 X 10(-3) for spleen, -2.33 X 10(-3) for gastrocnemius muscle, and -4.0 X 10(-3) for cardiac muscle.

OBJECTIVE: To compare the effect of moxibustion combined with basic treatment and simple basic treatment on the clinical symptoms, renal function and hypercoagulable state in patients with idiopathic membranous nephropathy (IMN) of low to medium risk with spleen-kidney deficiency and blood stasis. METHODS: A total of 60 patients with IMN of low to medium risk with spleen-kidney deficiency and blood stasis were randomized into an observation group (30 cases, 2 cases dropped off) and a control group (30 cases, 1 case dropped off). In the control group, the conventional basic treatment of anti-hypertension, regulating blood lipid and anti-coagulation was adopted. On the basis of the control group, moxibustion was applied at Shenshu (BL 23), Pishu (BL 20), Guanyuan (CV 4), Zusanli (ST 36) and Sanyinjiao (SP 6) in the observation group, once a day, 5 days a week continuously with 2 day interval. The treatment of 6 months was required in the both groups. Before treatment and 3 and 6 months into treatment, the total TCM syndrome score, the renal function indexes (24-hour urinary protein quantity [UTP], albumin [ALB], urea nitrogen [BUN] and creatinine [Scr]), the blood coagulation indexes (fibrinogen [FIB], D-Dimer [D-D], p-selection and von Willebrand factor [vWF]), total cholesterol (TC) and triacylglycerol (TG) levels were observed, and the therapeutic efficacy was evaluated on 3 and 6 months into treatment in the two groups. RESULTS: The effective rates of 3 and 6 months into treatment were 78.6% (22/28) and 89.3% (25/28) in the observation group, which were higher than 62.1% (18/29) and 75.9% (22/29) in the control group respectively ( CONCLUSION Moxibustion combined with basic treatment can effectively improve the clinical symptoms, renal function and renal microcirculation in patients with idiopathic membranous nephropathy of low to medium risk with spleen-kidney deficiency and blood stasis, the therapeutic effect is superior to the simple basic treatment.

The ralationship between traditional Chinese medicine (TCM) and intestinal microecology is increasingly being given more and more attention. Combined with the devolopment of intestinal microecology disciplines, effects of TCM on regulation of intestinal microecology have been gradually explained. Both clinical studies and animal experiments have confirmed that TCM can maintain the balance of intestinal microecology and regulate the intestinal flora. The author arrangemented the documents related to Chinese herbal compound adjusting intestinal flora in the recent ten years, summarized that the Chinese herbal compound which can strength spleen and replenish Qi, relax bowels and regulate Qi, dissipate dampness and check diarrhea, clear away heat and toxic materials, promote digestion and relieve stasis had certain regulation effects on intestinal microecology, providing basis for revealing the TCM essence of intestinal microecology.

Kinetin (Kn) is a cytokinin growth factor that exerts several anti-aging and antioxidant effects on cells and organs. To investigate the mechanism underlying apoptotic events in aging cells induced by D-galactose (D-gal), we examined the effect of Kn delivered via nuchal subcutaneous injection on D-gal-induced aging and apoptosis in rats. Our results showed that interleukin (IL)-2 levels and mitochondrial membrane potential (DeltaPsim) were decreased by Kn in aging rats while IL-6 production and apoptosis increased. In addition, the expression of anti-apoptotic Bcl-2 was low while that of Bax was high in the aging group. After treated with Kn, compared with aging group, there showed obvious difference in Kn group with elevated IL-2, proliferation index, Bcl-2, DeltaPsim and decreased IL-6 and Bax in splenic lymphocyte. Based on these results, we concluded that Kn can effectively protect the rat spleen from aging, apoptosis, and atrophy.

OBJECTIVETo analyze the effects of aging or advanced glycation on gene expression in the cerebrum and spleen of female C57BL/6J mice.

METHODSThe gene expression profile was determined by using cDNA expression arrays containing 588 cDNA.

RESULTSAging and advanced glycation resulted in differential gene expression patterns of cerebrum and spleen compared with young mice. Among the 80 genes detected in cerebrum, 43 exhibited a change in mRNA ratios with aging or treatment. Thirty-four changes (79%) were common in aged and D-galactose treated mice, whereas the cerebrum from aged and AGE-lysine treated mice showed common changes in expression of 38 genes (88%). Of the 86 genes detected in spleen, 29 (34%) displayed an age-related decrease in expression, whereas 3 (3%) displayed an increase in expression levels with aging. Eighteen genes from the detectable genes exhibited expression changes in both cerebrum and spleen of mice.

CONCLUSIONSThe gene expression profiles of D-galactose and AGE-lysine treated mice resemble those of aged mice. Use of cDNA hybridization arrays may provide a promising tool to explore the mechanism of aging at a molecular level.

The immune function of spleen after partial splenectomy (PSM) of rabbits was stuided using microwave tissue coagulation (MTC). Streptococcus pneumoniae suspension was injected into the ear veins of rabbits 4 weeks after they were subjected to partial splenectomy using microwave tissue coagulation (PSM) group and to sham operation (SO groups), respectively. India ink was given via portal vein. Residual spleen were resected and microscopic examinations were performed on spleen slices stained using HE to compare phagocytic functions of macrophage. Gradings of phagocytic function in macrophage were of no significant difference between PSM and SO groups (P > 0.05). Weights of spleens showed no significant difference between the two groups (P > 0.05). The phagocytic function of macrophage after PSM can be preserved well. The result of this experiment implies that splenic salvage using MTC is a clinically applicable method.

OBJECTIVETo compare the efficacy difference among acupuncture smoothing-liver and regulating-spleen method, regulating Governor Vessel method and oral administration of western medicine for menopausal insomnia.

METHODSOne hundred and fifty-six cases of menopausal insomnia were randomized into a smoothing-liver and regulating-spleen group (group A), a regulating Governor Vessel group (group B) and a medication group (group C), 52 cases in each one. Acupuncture at Zhongwan (CV 12), Daheng (SP 15), Sanyinjiao (SP 6) and Taichong (LR 3), etc. was applied in the group A; acupuncture at Baihui (GV 20), Fengfu (GV 16), Shenting (GV 24) and Yintang (GV 29), etc. was used in the group B; oral administration of estazolam tablets (1 mg each-day) was adapted in the group C, all once a day for totally 30 days. The each item score and total score in Pittsburgh sleep quality index (PSQI) were evaluated before and after treatment in each group, also the efficacy in each group was assessed.

RESULTSAfter the treatment, the sleeping rate in the group A and B was significantly higher than that in the group C (both P < 0.05); the total effective rate in the Group A and B was also significantly higher than that in the group C [86.5% (45/52) and 82.7% (43/52) vs 63.5% (33/52), both P < 0.05; the total cured rate in the group A was significantly higher than those in the group B and C [48.1% (25/52) vs 23.1% (12/52) and 25.0% (13/52), both P < 0.05]. Each item score and total score of PSQI were all improved after treatment in the group A and B (P < 0.01, P < 0.05), while only sleeping time, sleeping efficiency and total score were improved in the group C (all P < 0.05). The sleeping quality, sleeping time, sleeping difficulty and daytime dysfunction in the group A were all lower than those in the group C (all P < 0.05). The sleeping quality, sleeping time and daytime dysfunction in the goup B were all lower than those in the group C (all P < 0.05). The total score in the group A was significantly lower than that in the group B and C (both P < 05).

CONCLUSIONAcupuncture has better effect for menopausal insomnia than estazolam. Between the two acupuncture methods, the acupuncture method of smoothing-liver and regulating-spleen has a better effect.
