It was concluded that all compounds were isolated from this compound prescription for the first time.

OBJECTIVETo observe the effect of Chinese herbal therapy on T-lymphocyte subsets in patients with IgA nephropathy (IgAN).

METHODSTotally 36 inpatients and outpatients at Department of Nephropathy, Xiyuan Hospital, China Academy of Chinese Medical Sciences, from June 2011 to June 2013 were recruited in the treatment group, while 20 volunteers were recruited as the healthy control group. Patients in the IgAN group only took Chinese herbal decoctions by syndrome typing for 3 months (except those accompanied with hypertension additionally took antihypertensive agents such as angiotensin-converting enzyme inhibitor and/or dihydropyridines calcium antagonist). No intervention was performed in the healthy control group. The values of Th1, Th2, and CD4+ CD25+ Treg, and red blood cell number in urine were detected using flow cytometry before and after treatment. 24 h urine protein was detected using inmmunoturbidimetry.

RESULTSCompared with the healthy control group, the CD4+ CD25+ Treg level obviously decreased in the IgAN group, showing statistical difference (P < 0.01). In the IgAN group, Th1, 24 h urine protein, and urine red blood cell counts were obviously lower after treatment, showing statistical difference when compared with before treatment (all P < 0.05).

CONCLUSIONChinese herbal therapy could reduce urine erythrocyte number and 24 h urine protein of IgAN patients, and down-regulating Th1 expression might be its mechanism.

OBJECTIVETo study the impact of the water extract from Codonopsis thalictrifolia Wall (CTW) on the reproductive

METHODSWe divided 32 male SD infant rats into four groups of equal number to be treated intragastrical-system of male infant rats. ly with distilled water (control) and CTW at 10 g/kg (low dose) , 20 g/kg (medium dose), and 40 g/kg (high dose), respectively, twice a day for 2 weeks. Then we killed the rats, measured the levels of testosterone (T), luteinizing hormone (LH) and follicle-stimulating hormone (FSH) in the serum, obtained the testis weight, body weight, testis visceral coefficient and sperm concentration, and detected sperm viability, sperm motility and the level of cyclic adenosine monophosphate (cAMP) in the Leydig cells, followed by

RESULTSCompared with the control group, the low-dose, me-analysis of differences among different groups using the SPSS software. Medium-dose and high-dose CTW groups showed significant decreases in the serum T level ([3.09 +/-0.42] vs [1.22 +/-0. 32] , [1.06 +/- 0.29] and [0.57 +/-0.18] nmol/L, P<0.01), testis weight ([1.40 +/-0.16] vs [0.96 +/-0.09], [0.92 +/-0.11] and [0.91 +/- 0.08] g, P <0.01), and sperm concentration ([1.03 +/-0.16] vs [0.19 +/-0.07], [0.17 +/-0.08] and [0.16 +/-0.07] x 10(6)/ml, P <0.01), but a dramatic elevation in the testis visceral coefficient ([42.22 +/- 3.02] vs [51.39 +/- 3.09], [52.28 +/- 4.86] and [54.13 +/-6.06] mg/10 g, P <0.01); the medium- and high-dose CTW groups exhibited remarkable increases in the levels of serum LH ([13.62+/-0.89] vs [14.69 +/-0.12] and [14.93 +/-0.28] ng/L, P<0.01) and FSH ([4.32 +/-0.18] vs [4.77 +/-0.23] and [4.89 +/-0. 38] IU/L, P <0.05); all the three CTW groups showed markedly inhibited serum T secretion ([1.85 +/- 0.18] vs [1.42 +/-0.15], [1.12+/-0.18] and [0.88 +/-0.21] nmol/L, P<0.01) and intracellular cAMP ([5.51 +/-0.12] vs [4.39+/-0.06], [4.28 +/-0.07] and [4.11 +/- 0.10] nmol/L, P <0.01) in the Leydig cells.

CONCLUSIONThe water extract from CTW may reduce the synthesis of testosterone in the serum of male infant rats through the PKA pathway and consequently inhibit their testicular development and sperm production and affect the development of their reproductive system.

OBJECTIVETo explore the better therapy in the treatment of ganglion.

METHODSNinety cases of ganglion were randomized into a two-way quintuple puncture group, a common quintuple puncture group and a fire needling group, 30 cases in each one. In the two-way quintuple puncture group, the "9-in-1" multiple penetrating needling technique was used. In the common quintuple puncture group, the traditional "5-in-1" multiple penetrating needling technique was applied. In the fire needling group, the traditional multiple fire needling technique was adopted. The treatment was given once a day, 3 treatments made one session and the efficacy was analyzed statistically after 1 session treatment in the three groups.

RESULTSAll of the three therapeutic methods achieved the efficacy on ganglion. The curative rate was 96. 7% (29/30) in the two-way quintuple puncture group, which was better obviously than 66.7% (20/30) in the common quintuple puncture group and 60. 0% (18/30) in the fire needling group (both P<0. 01).

CONCLUSIONThe two-way quintuple puncture technique achieves the remarkably superior efficacy on ganglion as compared with the common quintuple puncture technique and fire needling technique.

OBJECTIVETo observe different effects of moxibustion on extracellular potassium ion in acupoint under physiological and pathological status and provide experimental evidence for exploring action mechanism of moxibustion on acupoint local.

METHODSForty female SD rats were randomly divided into a blank group, a blank-moxibustion group, a model group and a model-moxibustion group, 10 cases in each one. The complete Freund's adjuvant(CFA) was adopted to establish model of adjuvant arthritis (AA) in the model group and model-moxibustion group. No treatment was given in the blank group and model group while moxibustion was applied at "Zusan-li" (ST 36) for 30 min in the blank-moxibustion group and model-moxibustion group. The tissue fluid in "Zusanli" (ST 36) was collected with microdialysis and real-time analyzed by electrolytic analyzer. The change of concentration of potassium ion in "Zusanli" (ST 36) was observed.

RESULTS(1) Under physiological status, the concentration of extracellular potassium ion in the blank group was not changed within 150 min (P > 0.05); before the moxibustion, the concentration of extracellular potassium ion in the blank-moxibustion group was (1.21 +/- 0.31) mmol/L, and after treatment it was gradually increased and reached its peak at (2.38 +/- 0.42) mmol/L after 60 min (P < 0.05), then it was reduced. 150 min after the treatment, concentration of potassium ion was slightly higher than that before moxibustion as well as that in the blank group. The concentration in the blank-moxibustion group at 60 min was statistically significant compared with that in the blank group (P < 0.05). (2) Under pathological status, the concentration of extracellular potassium ion in the model group was not changed within 150 min, differences of which at each time point was not statistically significant (all P > 0.05). Before the moxibustion, the concentration of extracellular potassium ion was (1.09 +/- 0.12) mmol/L in the model-moxibustion group, and it was immediately increased to (1.96 +/- 0.18) mmol/L after moxibustion. 60 min and 90 min after the moxibustion, it still maintained a higher level, which was (1.87 +/- 0.29) mmol/L and (1.59 +/- 0.16) mmol/L respectively (both P < 0.05). The differences of each time point after moxibustion in the model-moxibustion group were statistically significant compared with those in the model group (all P < 0.05).

CONCLUSIONThe moxibustion could increase the concentration of potassium ion in rat's acupoint local under physiological status but time of effect is short; with moxibustion at "Zusanli" (ST 36) under pathological status, the concentration of local potassium ion is obviously increased and maintains for a long time.

OBJECTIVETo investigate the pre- and post-chemotherapy expression levels of Th1 and Th2 type cytokines in peripheral blood CD4(+) T lymphocytes, the changes of Th1/Th2 ratio and their clinical significance in patients with gastric cancer.

METHODSThe levels of specific cytokines in 60 gastric cancer patients were detected by flow cytometry before and after chemotherapy with FOLFOX4.

RESULTSThe level of IFN-gamma from peripheral blood CD4(+) T lymphocytes after chemotherapy in the whole group of gastric cancer patients was 11.4% +/- 5.0%, significantly higher than that (9.5% +/- 3.4%) before chemotherapy (P < 0.05). The level of IL-10 after chemotherapy was 3.6% +/- 1.2%, significantly lower than that (4.2% +/- 1.8%) before chemotherapy (P < 0.05). The ratio of Th1/Th2 (IFN-gamma/IL-4) after chemotherapy was 3.4 +/- 1.0 versus 3.4 +/- 1.6 before chemotherapy, without significant difference (P > 0.05). Interestingly, the levels of IFN-gamma and TNF-alpha of peripheral blood CD4(+) T lymphocytes in 15 gastric cancer patients who achieved partial response (PR) after chemotherapy were 14.8% +/- 8.0% and 5.9% +/- 2.0%, respectively, both were higher than that (6.9% +/- 2.5% and 4.2% +/- 1.3%) before chemotherapy (both P < 0.05). Furthermore, the ratio of Th1/Th2 (IFN-gamma/IL-4) after chemotherapy was 4.0 +/- 1.5, significantly higher than 2.5 +/- 1.2 before chemotherapy (P < 0.01).

CONCLUSIONEffective chemotherapy may reduce the tumor burden and relieve the shift of Th1/Th2 ratio. Improvement in immune function may be a very important therapeutic measure due to poor response of chemotherapy in gastric cancer patients.

The purpose of this study was to identify point mutation of the isocitrate dehydrogenase gene (IDH1 and IDH2) in patients with acute myeloid leukemia(AML) and its clinical significance. 90 de novo AML patients were selected for this study, the genomic DNA was served as template, the exon4 of IDH1 and IDH2 were amplified respectively. The IDH mutation was detected by using directly sequencing method for PCR product. The results indicated that among 90 de novo AML patients, 4 patients (4.4%) showed the IDH1 gene mutation positive, and 7(7.8%) patients showed IDH2 gene mutation positive. None was found harboring both mutations, the overall rate of mutation positive of them was 12.2%. In the AML patients with IDH gene mutation positive, the rate of normal karyotype was 72.7%, which was significantly higher than that in abnormality karyotype. The CR rate in mutation positive patients was 72.7%, which seemed as if higher than that in mutation negative patients, but without statistical significance. The mutation disappeared when the patients gained CR, and reappeared in same loci after relapse occurred. It is concluded that the IDH gene point mutation appears in normal karyotype patients, especially in patients combined with NPM1 gene mutation. The IDH gene mutation may be an important target for therapy and evaluating clinical prognosis of patients with normal karyotype.
