Objective To study the curative effect and mechanism of moxibustion on heat-sensitive acupoints combined with Erwei Badu Powder in the treatment of elderly herpes zoster (HZ) with type of stagnant heat of liver channel. Methods Sixty-five patients with HZ were randomly divided into treatment group (35 cases) and control group (30 cases). Two groups were orally given Longdan Xiegan Decoction and aciclovir conventionally, the treatment group was given moxibustion additionally on heat-sensitive acupoints combined with Erwei Badu Powder, and the control group was only given external application of Erwei Badu Powder for 10 days. The symptom scores, levels of T lymphocyte subsets and serum interleukin-2 (IL-2) were observed before and after treatment, the curative effect was evaluated, and PHN was followed up. Results The effective rate was 85.71%(30/35) in the treatment group and 66.67%(20/30) in the control group. The curative effect of treatment group surpassed the control group (P<0.05). Incidence of PHN was lower (P<0.01). The levels of CD4, CD4/CD8, and IL-2 increased and the level of CD8 decreased significantly in two groups compared with those before treatment (P<0.05). All indexes were better in the treatment group than those in the control group (P<0.05). Conclusion The curative effect of moxibustion on heat-sensitive acupoints combined with Erwei Badu Powder in treatment of elderly HZ is better than that of Erwei Badu Powder only, particularly in reducing the occurrence of PHN, improving neuralgia and insomnia. The mechanism may be related to increasing levels of CD4, CD4/CD8 and IL-2, and improvement of body’s cell-mediated immunity.

Objective To examine the application value of reticulocyte hemoglobin content (CHr)for diagnosing iron deficiency in premenopausal women.Methods The levels of CHr,hemoglobin (Hb), mean cellular volume(MCV),red cell distribution width (RDW) were measured on the ADVIA 120 (Bayer Diagnostics) automated hematology analyzer.Transferrin saturation (TS) and ferritin (SF) were measured on chemistry analyzer.Results CHr in iron deficiency without anemia group were significantly lower than that in the healthy control group (P＜0.01)and significantly higher than that in iron deficiency anemia group(P＜0.01).CHr in anemia of chronic disease group were significantly higher than that in iron deficiency anemia group(P＜0.01).Receiver operator characteristic curve (ROC) analysis in diagnosis of iron dificiency without anemia demonstrated that the area under the curve for CHr,SF,RDW,MCV,Hb were 0.872,0.798,0.721,0.713,0.677,respectively (P＜0.01).So CHr has a better overall sensitivity than SF,Hb,MCV and RDW in the diagnosis of iron deficiency without anemia.ROC also showed that the area under the curve for Hb,RDW,CHr,SF and MCV was 1.000,0.969,0.958,0.953 and 0.926,respectively (P＜0.01) in iron deficiency anemia.Conclusion CHr is the early and sensitive predictor of iron deficiency in premenopausal women,especially for the diagnosis of iron deficiency without anemia.

Objective Ultrasonongraphy and mammography were employed to estimate the pathological response of patients with breast cancer ,who had been accepted neoadjuvant chemotherapy .According to the pres-ent study ,we can provide additional evidence on therapeutic effect on evaluation of neoadjuvant chemotherapy and better selection of regime for breast cancer .Methods One hundred Thirty-six patients who were previously dia-gosed diagnosed with primary breast cancer were included in this study .All subjects were female with clearly pathological detection and accepted neoadjuvant chemotherapy about 4 to 6 cycles regardless of regime .The resid-ual tumor size was evaluated by mammography and /or ultrasonography before operation .Tumor size measured by image were compared with pathological size to predicting the accuracy of two types of imaging .Results Forty one of 116 records were undetectable imaging by mammogram and 19 of 106 records were undetectable by ultrasound which were considered a pathologic complete response .Sixty one(62.24%)of 98 patients who were accepted de-tection of mammogram and ultrasound would be predicted the tumor size by mammogram .Eighty three(84.69%) of 98 patients would be predicted the residual tumor by ultrasound .31 and 59 were accurately evaluated by mam-mogram and ultrasound , respectively .The result indicated that ultrasound was more accurate than mammogram (60.20%vs.31.63%,χ2 =16.11,P<0.001).The correctly rate was 92.85%(91/98)for ultrasound and 68. 37%(67/98) for mammogram.The diagnosis efficiency of ultrasound was more higher than mammogram ,even though there was no different significance between the two methods (χ2 =2.028,P=0.164).Conclusion Ultra-sonongraphy in estimating the residual tumor size after neoadjuvant chemotherapy of patients with breast cancer displays more accurately than mammography .

Aim: To study the pharmacokinetic effects of salvianolic acid B( Sal B) on danshensu( DSS) in Danshen injection in rats. MGthod: Following the intravenous administration of Danshen injection and Danshen injection added with Sal B to rats, the plasma kinetic study, tissue distribution and urine excretion were studied. The plasma kinetic study was also investigated by giving DSS and DSS in combination with Sal B to rats. Plasma, tissue and urine drug levels of danshensu were analyzed by LC-MS. Results: Compared with danshensu given alone, no significant difference of the pharmacokinetic behavior of danshensu was found when danshensu was given in combination with salvianolic acid B. However, compared with Danshen injection given alone, the pharmacokinetic behavior of danshensu changed remarkably when Danshen injection was given in combination with salvianolic acid B which might be caused by the decrease of DSS in kidney distribution and urine excretion. Conclusion: The pharmacokinetic effects of salvianolic acid B on danshensu depend on the existence of multiple components in Danshen injection. Results suggest that the pharmacokinetic interactions of the multiple components are closely related to the integrity of herbal medicines.

Objective To investigate the effect of lateral ventricle transplantation of neurotrophic factor-transfected cells derived from Glia cell line on vascular dementia in rats and gene expression of Drebrin in hippocampal region.Methods By using gene clone technique,the GDNF gene was transfected into SH-SY5Y cell lines.104 adult male Sprague-Dawley rats weighing (200± 20) gram were divided into groups:transplanted group,injected group,control group,all of which accepted operation by permanent ligation of left common carotid artery and clipping right common carotid artery repeatedly to build up model of vascular dementia,and sham operation group which accepted no ligation or clipping.6 rats from each group were decapitated on the third day,seventh day and tenth day after transplanting treatment were for fluorescence detection.The rest 20 rats in each group were used to detect learning and memory functions by Morris water maze on the third day and decapitated on the fourth day after transplanting treatment.Then GDNF level in temporal lobe were detected by enzyme-linked immunosorbent assay (ELISA),while Drebrin mRNA and protein levels in hippocampal region were detected by real time-PCR and Westernblot respectively.Results There was strong fluorescent light detected around lateral ventricle of rats in transplanted group on the third day after transplantation,which faded on the seventh day and disappeared on the tenth day.The learning and memory functions of rats in transplanted group were improved significantly.The escape latency was shorter in transplanted group than in injected group and control group [(34.89±4.15) s vs.(43.86±6.95) s,(50.89±3.66) s,both P＜0.05],while shuttle times through the third quadrant were more often in transplanted group than in injected group and control group [(11.00±1.49) vs.(9.26 ±1.38),(8.04 ± 1.12),both P＜0.05].GDNF level and Drebrin mRNA and protein levels were higher in transplanted group than in injected group and control group [GDNF:(315.71±27.43) vs.(256.26±19.90),(141.95±21.33),Drebrin mRNA:(5.54±0.35) vs.(3.10±0.33),(1.32±0.23),Drebrinprotein:(0.55±0.05) vs.(0.43±0.06),(0.26±0.06),all P＜0.05].Conclusions GDNF-transfected cells could survive in the lateral cerebral ventricle of rats for about seven days.The method for treating vascular dementia through the technique of transplanting GDNF-transfected cells is certain feasible,which has a better therapeutic effect than GDNF-injection directly into lateral cerebral ventricle.The therapeutic effect of GDNF on vascular dementia may be related to its action of regulating neural plasticity.
