The tuberous roots of Aconitum carmichaeli are largely used in traditional Chinese medicine and widely grown in Jiangyou, Sichuan, China. During the growth process, this medicinal plant releases a large amount of allelochemicals into soil, which retard the growth and development of near and late crops. Therefore, a pure culture experiment was thus carried out by seed soaking to study the allelopathic effects of extracts from tuberous roots of A. carmichaeli (ETR) on the seed germination and young seedling growth of Lolium perenne, Trifolium repens, and Medicago sativa, the late pasture grasses after cultivation of A. carmichaeli. The results showed that three pasture grasses varied significantly in seed germination and young seedling growth in response to ETR concentrations. Seed germination of M. sativa was stimulated by low ERT concentration (0.01 x g(-1)), while all of pasture grass seeds germinated poorly in solution with 1.00 g x L(-1). Seed soaking with 1.00 g x L(-1) also inhibited significantly the growth of pasture young seedlings, with M. sativa showing the highest seedling height reduction of 42.05% in seeding height, followed by T. repens (40.21%) and L. perenne with about 11%. Cultivation of L. perenne could thus be beneficial to increase whole land productivity in A. carmichaeli-pasture grass cropping systems. In addition, hydrolysis of protein, starch, and inositol phosphates was blocked and free amino acids, soluble sugars and phosphorus were decreased in seeds by seed soaking with ETR, which could be one of the reason for the inhibition of seed germination. There was a significant reduction in root vigor, nitrate reductase, and chlorophyll after the seed treatment with ETR, indicating the suppression of nutrient uptake, nitrate assimilation, and photosynthesis by allelopathic chemicals in ETR, which could lead to the slow growth rate of pasture grass seedlings.

Objective To compare the safety and feasibility of thoracoscopic extrapleural Nuss procedure with traditional intrapleural Nuss procedure. Methods Total 252 patients with pectus excavatum received Nuss surgery from July 2008 to June 2009 in Beijing children' s hospital. Patients had following condition were excluded; (1) recurrent pectus excavatum; (2) complicated with other diseases, and need simultaneous surgery; (3) older than 13-year-old; (4) extensive depression, and need two Nuss bar; or (5) extreme severe or severe unsymmetric. 131 cases were selected in our study and they were randomly divided into two groups, thoracoscopic extrapleural Nuss procedure ( n = 62 ) and traditional intrapleural Nuss procedure ( n =69). Perioperative information, postoperative complications, effectiveness and the location of the Nuss bar were compared between two groups. Results All the 131 patients had completed the procedure successfully. There were no significant differences in age, Haller index; surgical effects, operation time, blood loss, and hospital stay, between two groups. Postoperative complications between the two groups are not significant. 131 patients were followed up from 14 to 26 months, and no recurrence and long-term complications occurred. About more than half cases of extrapleural Nuss procedure group were break the pleural into thoracic cavity. Conclusion Both extrapleural and intrapleural Nuss procedure are safe and effective for pectus excavatum, but extrapleural Nuss procedure have no advantage to the intrapleural Nuss procedure, also it' s hard to observe the other side of thoracic cavity during the surgery, and not easy to grasp and to promote.

Objective To investigate the effect of magnesium sulfate on NF-κB p65,inflammatory cyto-kines in brain and serum of preeclampsia model rats by magnesium sulfate. Methods The healthy SD rats were randomly divided into 4 groups,normal pregnancy group(n = 10),magnesium sulfate control group(n = 10), preeclampsia(PE)model group(n = 10)and magnesium sulfate intervention group(n = 10). Blood pressure, urinary protein,blood urea nitrogen and alanine aminotransferase levels were detected in rats in each group. RT-qP-CR and ELISA were used to detect the expression of IL-1β,TNF-αand IL-6 in the brain and serum. Western blot assay was used to detect the expression of the NF-κB p65 in brain. Results The level of proteinuria,blood urea nitrogen and blood pressure in PE model rats were significantly higher than those in the normal pregnancy group and those in the magnesium sulfate intervention group at 20 days of gestation(P<0.05). Results of RT-qPCR and ELISA assay showed that IL-1β,TNF-α and IL-6 level in magnesium sulfate intervention group were sig-nificantly lower than those in PE model group(P<0.05),but still higher than those in the normal pregnancy group (P < 0.05). Western blot result showed that NF-κB p65 in the magnesium sulfate intervention group was lower than that in the PE group(P<0.05),but still higher than that in the normal pregnancy group(P<0.05). Con-clusion The prevention and treatment preeclampsia mechanism of magnesium sulfate may inhibit inflammatory cyto-kines through NF-κB p65 pathway in the preeclampsia model rats.

Professor YU Ren-cun believes that the responsibility of cough and asthma of lung cancer patients not only lies in the lungs, but also relates with spleen, kidney, heart and liver. Treatment should focus on the whole body and overall conditioning. Syndrome can be divided into 4 types: qi deficiency with phlegm resistance, yin deficiency with toxic heat, qi stagnation with blood stasis, and lung and kidney deficiency. Clinical treatment should pay attention to the combination of disease and syndrome, which can achieve satisfactory efficacy.

OBJECTIVE:
Comparative analysis of the clinical curative effect of manipulative reduction and TRV- CRP treatment of BPPV, comfort degree during reset and quality of life improvement.
METHOD:
One hundred and thirty-two patients with BPPV were randomly divided into two groups ,one group underwent the traditional manip- ulative reduction, the other group with TRV-CRP. DRI and VAS was evaluated in the pre and after treatment and evaluation of the efficacy was conducted. The results of two groups were compared.
RESULT:
The effective rate of manipulative reduction after a week treatment was 89. 23% and TRV-CRP.was 98. 51%, which was higher in TRV-CRP group than that of the manipulation reduction group(P<0. 05). The comfort degree of the manipulation reduction group was 4. 54±2. 48,higher than the TRV-CRP group which was 5. 48±1. 44 (P<0. 05). The score of DHI showed no significant difference before treatment between manipulation reduction group and TRV-CRP group(P>0. 05), the score of the two groups were decreased after a week of reduction, but the improvement of TRV-CRP group was higher than that of manipulation reduction group(P<0. 05).
CONCLUSION
The success rate of TRV-CRP was higher than that of manipulative reduction,but manipulative reduction comfort degree was higher than TRV-CRP, the two methods can both improve the quality of life of patients with BPPV. TRV-CRP has many advantages over manipulative reduction, but manipulative reduction is simple with low cost, and the effect is still a great advantage. In clinical work, we should reasonable combine the two methods,so as to improve the cure rate of RPPV.

ABSTRACT:Hypertension,the first risk factor for stroke and coronary heart disease in the Chinese population, seriously endangers people’s health.At present,China has more than 270 million people with hypertension and an annual increase rate of 1 0 million people.Then how to improve prevention and treatment of hypertension has become an urgent need to solve major medical and social problems.In the past,research on hypertension mainly focused on the peripheral area,while recent research has shown that the central regulation plays an important role in the development of hypertension. Hypothalamic paraventricular nucleus (PVN ), which plays a key role in maintaining cardiovascular activity, can directly control the sympathetic preganglionic neurons and regulate peripheral sympathetic nerve activity,thus being closely related to the development of hypertension.Research in recent years shows that the comprehensive effects of proinflammatory cytokines (PIC ),reactive oxygen species (ROS),renin-angiotensin system (RAS),neurotransmitter (NT)and nuclear factorκB (NF-κB)are involved in the pathogenesis of hypertension.However,it is unclear how these neurohormones in PVN are activated,how they interact with each other and what role they play in the regulatory mechanism of hypertension.Therefore,the key focus of this research is to explore the impact of activated neurohormones in PVN on hypertension.This study will provide new content for the study on hypertension.
