OBJECTIVETo observe the efficacy difference in the treatment of breast hyperplasia between the combined therapy of auricular point sticking and Xiaopijian and the simple application of Xiaopijian.

METHODSNinety-one patients were randomized into an observation group (46 cases) and a control group (45 cases). In the observation group, the sticking therapy on the auricular points was applied in combination with the oral medication of Chinese herbal medicine, Xiaopijian. Auricular points included Ruxian, Neifenmi (CO18), Luanchan, Shenmen (TF4), Gan (CO2), Pi (CO13). The auricular point sticking therapy was applied once a week on the auricular points of one side alternatively. Xiaopijian was the self-prepared decoction. The main ingredients are radix bupleuri Bupleurum chinense, spica prunellae prunella vulgaris and radix peoniae alba Paeonia lactiflora, 30 mL each time, three times a day. In the control group, Xiaopijian was simply prescribed for oral administration, 30 mL each time, 3 times a day. The treatment was discontinued during menstruation in the two groups. The menstrual cycle of one month made one session of treatment. The treatments for 3 sessions were observed. The scores of symptoms and physical signs, including the degree of breast pain, hardness and size of breast masses as well as the scores of general and supplementary symptoms were compared before and after treatment in the patients of the two groups. The clinical efficacy was compared between the two groups.

RESULTSAfter treatment, the scores of symptoms and physical signs were reduced apparently as compared with those before treatment in the patients of the two groups (both P<0. 05). The score reduction in the observation group was much more than that in the control group (11.02±1. 78 vs 9.82±1. 53, P<0. 05). The total effective rate was 95.7% (44/46) in the observation group, higher apparently than 80. 0% (36/45, P<0. 05).

CONCLUSIONThe combined therapy of auricular point sticking and Xiaopijian achieves the superior efficacy on breast hyperplasia as compared with the simple application of Xiaopijian.

Objective To observe the levels of Livin and Caspase-3 in renal tissue of rats following acute paraquat (PQ) poisoning and the intervention effects of ulinastatin (UTI) . Methods Fifty-four Sprague-Dawley (SD) rats were randomly divided into three experimental groups: control group (group A),PQ poisoning group (group B) and UTI group (group C) (n = 18 in each group) . Rats in group B and group C were administered intragastrically with 80 mg/kg PQ, and rats in group C were treated with 100,000U/kg ulinastatin injected intra-psritoneally once a day; and rats in group A were administered intragastrically with the same volume of saline instead of PQ. At 24, 48, 72 hours after poisoning, the levels of Livin in renal tissue were detected by Westen blotting and the levels of Caspase-3 were detected by immunohistochemistry 24, 48, and 72 hours after poisoning, and the histopathological changes of renal tissue were observed at the same time. Results In the group A, the structure of renal tissue was distinct. In the group B, the distinctness of the structure of renal tissue declined significantly, and swelling, edema and vacuolar degeneration were observed 24 h after poisoning, and pathological changes became more and more obvious keeping pace with time elapsing, and sometimes karyopyknosis appeared and celluar structures disappeared with involvement of renal glomerulus and medulla. These pathological changes were significantly lessened in rats of group C. In the group A, there was little Caspase-3 in renal tissue of rats. Twenty-four hours after poisoning, the caspase-3 in renal tissue of rats of group B was found on the membrane and in the kytoplasm of renal tubular epithelial cells of cortical part. Compared with group B, the level of Caspase-3 in renal tissue of rats of group C decreased significantly to lower level (P ＜0. 01 ) . Compared with group A,the levels of Livin in renal tissue in rats of group B and group C increased significantly at all different intervals (P ＜0. 01 ), and as group B was compared with group C, the difference was statistically significant (P ＜0. 01 ) . Conclusions The main pathologyical changes of renal injury induced by PQ are epithelial swelling, vacuole degenerateion and necrosis. Caspase-3 is involved in the process of renal injury. UTI has a protective effect on the renal tissue of rats following paraquat poisoning through up-regulating the level of Livin and down-regulating the level of Caspase-3, however, the regulation mechanism as well as the pathway is still needed to further study.

Objective Paraquat(PQ) is an effective herbicide which is widely used in agricultural production .PQ poisoning is frequently seen in humans with the lung as the target organ ,but the poisoning mechanisms is not very clear .Studies show that endoplasmic reticulum stress(ERS) is closely associated with poisoning , but there are few reports on the relationship between ER stress and PQ poi-soning.This article was to investigate the effects of ERS-induced apoptosis and total flavonoids from astragalus complanatus (FAC) in a-cute lung injury(ALI) following paraquat poisoning in rats . Methods A total of 30 adult healthy Sprague-Dawley (SD) rats were ran-domly divided into 3 groups:control group, ALI group, ALI+FAC group and ALI+saline group.Biochemical method was applied to de-tect superoxide dismutase (SOD), catalase (CAT) and malondialdehyde (MDA) in lung tisssue,TdT-mediated dUTP nick end labeling (TUNEL) assay in observing lung apoptosis, Western blotting and real-time PCR(RT-PCR) in detecting the changes in expressions of C/EBP homologous peotein (CHOP), activating transcription factor 4 (ATF4) and X-box binding protein 1 (XBP) following ALI, and HE staining in observing the pathological changes of lung tissue . Results Compared with control group , the expression of MDA content was enhanced in ALI group ([3.26 ±0.24] vs [5.04 ±0.36],P<0.01), along with significantly decreased activity of SOD and CAT ([300.26 ±35.69] vs [187.21 ±25.66]), ([5.78 ±1.28] vs [2.15 ±1.12],P<0.01), increased cell apoptosis , upregulated pro-tain level of CHOP ([0.74 ±0.20] vs [0.23 ±0.07],P<0.01) and mRNA expression of ATF4, XBP1 and CHOP.However, FAC sig-nificantly attenuated ALI following PQ , as showed by reduced MDA content , enhanced activity of SOD and CAT , decreased cell apopto-sis, inhibited protain level of CHOP and mRNA expression of ATF 4, XBP1 and CHOP ([5.04 ±0.36] vs [3.99 ±0.27],P<0.01). Furthermore, the activity of SOD and CAT were higher in FAC pretreatment group than those in ALI group ([ 0.74 ±0.20 ] vs [0.42 ±0.11],P<0.01). Conclusion From the research, ERS-induced cell apoptosis is involved in ALI following PQ , and the protec-tive role of FAC in lung tissue following PQ is due to its effect in atten-uating ERS-induced apoptosis .

Objective To investigate the effect of total flavonoids from astragalus complanatus (FAC) on attenuating lung injury resulted from paraquat (PQ) poisoning by inhibiting excessive endoplasmic reticulum stress (ERS) and c-Jun N-terminal kinase (JNK) pathway in rat.Methods Forty-eight Sprague-Dawley (SD) rats were randomly divided into six groups (n=8 in each group),including control group,model group,dimethyl sulfoxide (DMSO) vehicle control group,and FAC in low,medium,and high dosage groups.The model was reproduced by giving PQ 80 mg/kg orally to induce lung injury.The rats in control group were treated with saline by gavage.The rats in DMSO group were given 10％ DMSO 20 mL/kg by gavage 2 hours before intraperitoneal injection of PQ,and those in FAC low,medium and high dosage groups received 40,80,160 mg·kg-1· d-1 of FAC solution intraperitoneally after the PQ administration.The rats were sacrificed 72 hours after giving PQ,and the left lung tissue was harvested 72 hours after the reproduction of experimental model.The ratio of wet/dry weight (W/D) and total lung water content (TLW) were determined.The pathohistological changes of the left lung was observed under light microscope,and scored with alveolar damage index of quantitative assessment (IQA).The mRNA expressions of JNK and glucose regulated protein 78 (GRP78) were determined by reverse transcription-polymerase chain reaction (RT-PCR),and the protein expression of JNK,phosphorylation-JNK (p-JNK),and GRP78 were determined by Western Blot.Results Compared with control group,the W/D ratio,TLW and IQA were increased significantly in model group and DMSO group,and the mRNA expressions of JNK and GRP78 and the protein expressions of JNK,p-JNK and GRP78 were markedly increased.Compared with the model group,the W/D ratio,TLW and IQA,and the expressions of JNK mRNA and p-JNK protein were significantly decreased in the FAC groups,especially in FAC high dosage group [W/D ratio:3.0 ± 0.3 vs.5.5 ± 0.5,TLW:2.2 ± 0.3 vs.4.7 ± 0.4,IQA:(15.4 ± 3.0)％ vs.(40.0 ± 5.7)％,JNK mRNA:0.21 ± 0.08 vs.0.82 ±0.27,p-JNK protein:0.31 ±0.09 vs.0.78 ±0.25,all P＜0.O1].The mRNA expression of GRP78 and the protein expressions of JNK and GRP78 were highly expressed in FAC low,medium and high dosage groups,and there was no significant difference compared with those in model group (GRP78 mRNA:0.54 ± 0.18 vs.0.74 ± 0.20,JNK protein:0.76 ± 0.27 vs.0.80 ± 0.28,GRP78 protein:0.51 ± 0.18 vs.0.69 ± 0.21,all P＞0.05).Conclusions PQ induces excessive ERS in the lung tissue resulting in lung injury.FAC has a protective effect on lung against PQ injury,and it may be related with inhibition JNK pathway in ERS.
