OBJECTIVETo analyze the relationship between Chinese medical constitutions and chemotherapy-induced leucopenia (CIL) of primary breast cancer patients.

METHODSTotally 306 breast cancer patients undergoing adjunctive chemotherapy for the 1st time, and effective 291 breast cancer patients were recruited in this study.Nine Basic Constitutional Scale was used before first chemotherapy. Chinese medical constitutions were classified and quantitatively scored. The highest grading for any item of adverse reactions in each case during the whole chemotherapy course was recorded after chemotherapy. Data were statistically analyzed using SPSS16.0.

RESULTSThere was no significant difference in CIL between different chemotherapy regimens and various Chinese medical constitutions of breast cancer patients (P > 0.05). Yang deficiency constitution is one risk factor for CIL. The higher the score of yang deficiency constitution, the more severe the CIL.

CONCLUSIONSYang deficiency constitution was correlated with the degree of CIL. The higher the score of yang deficiency constitution, the greater the risk of III-IV grade CIL in breast cancer patients.

BACKGROUND: Limb negative pressure treatment can dilate limb vessels and improve terminal microcirculation. P-substance has strong vasodilative activity and is involved in the sensation of the skin to traumatic stimulation and the modulation of local vascular function.OBJECTIVE: To observe the influence of limb negative pressure on cutaneous P-substance immunoreactive nerve fibers in dogs with peripheral arterial occlusive disease.DESIGN: Randomized controlled experiment.SETTING: The 3rd Department of General Surgery, Xijing Hospital Affiliated to the Fourth Military Medical University of Chinese PLA.MATERIALS: This experiment was conducted at the Animal Laboratory of Xijing Hospital Affiliated to the Fourth Military Medical University of Chinese PLA between April 2003 and May 2004. Totally 17 healthy hybrid dogs were randomized into 3 groups, namely, treatment group of 10 dogs,non-treatment group of 5 dogs, and normal control group of 2 dogs.INTERVENTIONS: Negative pressure treatment on affected limbs: After superficial anesthesia, the left hindlimbs of the animals were put into the home-made negative cabin for negative pressure treatment with pressure designed as -12kPa, for 15 minutes, once a day for consecutive 10 days.[1] Treatment group: The left hindlimb ischemic model was prepared 14days before starting 10-day negative pressure treatment; after that the animals were subjected to infusion, the skin of the 2nd toe of affected limbs, as well as L1-5 spinal cords and dorsal root ganglion were obtained for immunohistochemical (IHC) staining. Meanwhile prostaglandin E1 immunoreactive nerve fibers were detected. [2] Non-treatment group: The animals received the same treatment and examination as treatment group except for negative pressure. [3] Normal control group: No ischemic model was prepared or negative pressure treatment was given except for IHC staining.MAIN OUTCOME MEASURES: Changes of cutaneous P-substance immunoreactive nerve fiber in each group. RESULTS: Totally 17 dogs entered the result analysis. Changes of cutaneous P-substance immunoreactive nerve fibers: The cutaneous P-substance immunoreactive nerve fibers in dermis connective tissues and layer vessels were reduced in treatment group compared to those in non-treatment group[(24.70±4.6), (43.49±6.3) μm/mm2, P ＜ 0.01], but still higher than those in control group [(18.10±5.4) μm/mm2, P ＜ 0.01]; dermis P-substance immunoreactive nerve fibers in non-treatment group were more than those in normal control group (P ＜ 0.01), with P-substance immunoreactive nerve fibers increased and deeply stained in dermis connective tissues and small vessels. In contrast, P-substance immunoreactive nerve fibers were not observed in the horny layer but in the dermis of the toe in normal control group.CONCLUSION: Results of the present study suggest that limb negative pressure can enhance P-substance release from cutaneous sensory nerve fibers.

Human tissue kallikrein-binding protein (Kallistatin, KAL), a secretory protein that participates in the regulation of multiple signaling pathways by binding to the extracellular receptor, however, at present has not been reported about the intracellular activity, and whether it has the similar biological activity with extracellular activity. Here we constructed no signal peptide KAL (NSK) into the adeno-associated virus vector to explore the intracellular activity of KAL. Both the endothelial cell and lung cancer cells could express KAL, but not secreted after rAAV2-NSK transfection. The proliferation and migration of human umbilical vein endothelial cells (HUVECs) were inhibited, but the apoptosis rate was not affected. The proliferation rates, mobility and tubule formation of all the three tested lung cancer cells, such as NCI-H446, NCI-H460 and A549, were inhibited to different extents. This cellular study not only confirmed the intracellular activity, but also suggested it may serve as a kind of "balance factor" in multi-targeted controlling, which may provide a new train of thoughts to explain the regulatory contradiction in PI3K-Akt signaling pathways by KAL.

OBJECTIVETo observe the effect of Chinese herbs for stasis removing and collaterals dredging (CHSRCD) upon angiotensin-converting enzyme 2-angiotensin-(1-7)-Mas axis in the renal cortex of diabetic nephropathy rats.

METHODSTotally 89 male Sprague-Dawley rats were randomly divided into the blank control group (C group, n=22), the high-glucose high-fat control group (H group, n=10), and the streptozotocin (STZ)-injecting group (n=57). The diabetes rat model (n=50) was induced by feeding high-glucose high-fat diet in combination with intraperitoneal injection of STZ, which were further divided into the model group (M group, n=24), the irbesartan group (I group, n=13), and the CHSRCD (Z group, n=13). Rats in I and Z groups were intragastrically fed with suspension of irbesartan and CHSRCD, once daily for 16 weeks. Equal volume of drinking water was administrated to rats in the rest groups. Blood glucose and 24 h urine protein quantitation were tested at four time points. And the mRNA expression of ACE2 and Mas at various time points was detected by Real-time PCR, immunohistochemical assay, and Western blot. Quantitative analyses of ACE2 and Mas protein expression were performed at the end of week 16.

RESULTSCompared with the C group, blood glucose increased in the H and M groups (P < 0.01). It was higher in the H group (P < 0. 01). 24 h urine protein quantitation at different time points increased in the M group, and it was higher than that in the H group (P < 0.05). Compared with the M group, 24 h urine protein quantitation decreased at the end of week 8 in the I group, and at the end of week 8 and 16 in the Z group (P < 0.05). It was lower in the Z group than in the I group at the end of week 16 (P < 0.05). Compared with the C and H groups, the expression of ACE2 mRNA in the renal cortex was lower in the M group at the end of week 16 (P < 0.01). Compared with the M group, it was higher in the Z group (P < 0. 01). There was no statistical difference in the expressions of Mas mRNA at the end of week 16 between the C group and the M group (P > 0.05). It was lower in the M group than in the H group (P < 0.05). It was higher in the Z group than in the M group (P < 0.05), and higher than in the I group (P < 0.05). The expression of ACE2 and Mas protein in the M group decreased as time went by. The expression quantitation of ACE2 and Mas protein at the end of week 16 was lower in the M group than in the C group (P < 0.05). Compared with the M group, ACE2 expression of the Z group and Mas of the I and Z groups increased more significantly (P < 0. 05).

CONCLUSIONCHSRCD could play a role in renal protection for diabetic nephropathy rats by up-regulating the mRNA and protein expression of ACE2 and Mas, promoting the ACE2-Ang-(1-7)-Mas axis, and lowering urinary protein.
