Objective To investigate the effects of Xinnaoxuemianning combined with statins on carotid atherosclerotic plaque in patients with cerebral infarction. Methods 180 cerebral infarction patients were divided into the observation group (90cases) and the control group (90cases) by random number table method. The control group was given atorvastatin calcium tablets and the observation group was given additionally Xinnaoxuemianning. The changes and prognosis of carotid atherosclerotic plaques were evaluated before and after treatment, and the incidence of adverse reactions was counted. Results There were no differences in the carotid atherosclerotic plaque, TCM syndrome score and neurological deficit severity between the two groups before treatment. After treatment, the above indexes were significantly improved, and the increasing degree of the observation group was better than that of the control group. The incidence rate of adverse reactions was lower in the observation group than that in the control group (5.56％ vs.13.33％) (P<0.05). Conclusion Xinnaoxuemianning can reduce the carotid atherosclerotic plaque area and correct the unstable plaques in patients with cerebral infarction.

Objective By observing the clinical efficacy of acupuncture plusBu Shen Jie Yu Qing Xin decoction (herbal decoction for tonifying kidney, anti-depression and clearing heart fire) in treating perimenopausal depression, to discuss about the effect of acupuncture plus medication on Hamilton Depression Scale (HAMD), Self-rating Depression Scale (SDS) and hypothalamic-pituitary-ovarian (H-P-O) axis in perimenopausal depression patients.Method By following a completely randomized design, sixty perimenopausal depression patients were divided into a Chinese medication group (Bu Shen Jie Yu Qing Xin decoction) with 30 cases, and an acupuncture-medication group (acupuncture plusBu Shen Jie Yu Qing Xin decoction) with 30 cases, to receive 12-week treatment in total. The HAMD and SDS were estimated prior to the treatment and in the 4th, 8th and 12th weeks; the serum follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), testosterone (T), prolactin (PRL), and progesterone (P) contents were detected before and after the treatment.Result Acupuncture plus medication and Chinese medication alone were both effective in treating perimenopausal depression, and the therapeutic efficacy of acupuncture plus medication was superior to that of Chinese medication alone (P<0.05). In the acupuncture-medication group, the HAMD score dropped significantly in the 4th, 8th and 12th weeks compared to that before the treatment, and the score dropped significantly in the 8th and 12th weeks compared to that before the treatment in the Chinese medication group (P<0.01). The HAMD score in the acupuncture-medication group was significantly lower than that in the Chinese medication group in the 4th, 8th and 12th weeks (P<0.01). After the treatment, the items including anxiety, insight, sleep, and despair were significantly changed in the Chinese medication group (P<0.05); 7 items were significantly changed in the acupuncture-medication group (P<0.05). The scores of anxiety, insight, sleep, diurnal-nocturnal, obstruction, and body weight in the acupuncture-medication group were significantly superior to those in the Chinese medication group (P<0.05). The SDS score dropped significantly in the 4th, 8th and 12th weeks in the acupuncture-medication group, and in the 8th and 12th weeks in the Chinese medication group (P<0.01,P<0.05); in the 4th and 8th weeks, the SDS score in the acupuncture-medication group was significantly lower than that in the Chinese medication group (P<0.05), while the between-group difference was statistically insignificant in the 12th week (P>0.05). After 12-week treatment, the contents of FSH and LH declined significantly in both groups (P<0.01, P<0.05), and the contents of E2 and T increased significantly in the acupuncture-medication group (P<0.01,P<0.05). The decrease of FSH and LH, and the increase of E2 were more significant in the acupuncture-medication group (P<0.05,P<0.01).Conclusion Acupuncture plus medication can improve the symptoms of perimenopausal depression, and it takes a faster action than Chinese medication alone. Acupuncture plus medication can mitigate 7 items in HAMD, while Chinese medication can improve anxiety, insight, sleep and despair. Acupuncture plus medication can produce a more significant efficacy in improving anxiety, insight, sleep, diurnal-nocturnal, obstruction, and body weight compared to Chinese medication. For perimenopausal depression, acupuncture plus medication can correct the endocrine disorder and improve depression state by down-regulating the levels of FSH and LH, and up-regulating the contents of E2 and T to improve the function of H-P-O axis.

Objective To compare the immune protective effects of three antigens of Trichinella spiralis encapsulated larvae on mice.Methods The mice were immunized with Trichinella spiralis encapsulated larvae somatic antigen,encapsulated larva excretory-secretory antigen and encapsulated larva surface antigen,3 times with a 7-day interval,and the adjuvant control and normal control group were set up.Seven days after the final immunization,each mouse was orally challenged with 200 Trichinella spirais larvae.The intestinal adult worms and muscle larvae of Trichinella spiralis of each group were recoveried and examined on Day 7 and Day 30 post-challenge,respectively.The level of 8eruln IgG to antigens of Trichinella muscle muscle larvae wa8 detected by ELISA.Results The intestinal adult worms were reduced by 84.89%.89.73%,85.65%.2.57% in the encapsulated larva somatic,excretory-secretory and surface antigen groups,respectively.The muscle lalwae were reduced by 71.71%,80.98%,73.66%,5.60%, respectively.Adtlltwornl reduction rates(P<0.05) and musclelarva reduction rates(P<0.01) of the encapsulated larva excretory-secretory antigen group and surface antigen group were higher than those of encapsulated larva somatic antigen group.The antibody titers in all the immunized groups increased significantly.and the GMRT values of the encapsulated larva somatic,excretory-secretory and surface antigen groups were 32 798.89,3 474.51,2 984.83,respectively,and were 6.09,7.56,6.50 times higher than those of the normal control group(459.32).Conclusions Trichinella spiralis encapsulated larva antigens can induce strong resistance of host to a subsequent challenge infection.Among these antigens,excretory-secretory antigen is more immunogenic.

OBJECTIVETo explore the effect of Tanshinone II A on severe acute pancreatitis (SAP) lung injury (ALI) rats and its possible mechanism.

METHODSSD rats were injected with sodium taurocholate to induce SAP group, and then intervened with sodium tanshinone II A sulfonate ( STS group). Simultaneously a sham-operation group (SO group) was set up. There were 24 rats in each group. The survival state and wet-to-dry weight ratio of lung tissues were observed. Activities of myeloperoxidase (MPO) in lung were determined by MPO reagent kit. Pathologic changes of lung tissues were determined by Hofbuaer method. Expression levels of three cytokines, TNF-alpha, IL-1beta, and intercellular cell adhesion molecule-1 (ICAM-1) were detected by ELISA.

RESULTSThe survival state of rats in the SAP group was deteriorated. The wet-to-dry weight ratio, MPO activities, pathologic changes in lung tissues, and expression levels of TNF-alpha, IL-1beta, and ICAM-1 increased significantly more in the SAP group than in the SO group (P < 0.05). Compared with those in the SAP group, the survival state of rats in the STS group was improved; the wet-to-dry weight ratio, MPO activities, pathologic changes in lung tissues, and expression levels of TNF-alpha, IL-1beta, and ICAM-1 obviously decreased in the STS group (P < 0.05).

CONCLUSIONTanshinone II A had remarkable effect on SPA LI rats, which might be associated with changing cytokines levels and attenuating infiltration of lung inflammatory cells.
