Objective To investigate the effect of hyperbaric oxygen( HBO) in craniotomy for traumatic brain injury. Methods The 90 patients with traumatic brain injury who received craniotomy in our hospital from March 2012 to September 2014 were divided into the obser-vation group(51 cases) which received HBO therapy additionally and the control group(39 cases). The remission rate of brain edema,GCS score,incidence of lung infection,infarction incidence and subdural effusion incidence at the same course of HBO treatment between the two groups were observed and compared. Rsults The remission rate of cerebral edema of observation group was higher than that of control group after a course of HBO treatment. And 6 days,9 days,12 days and 15 days after the course of HBO treatment,the GCS scores of observation group/control group were 8. 2/7. 8,9. 8/9. 0,11. 2/10. 3 and 12. 2/12. 0,respectively. The lung infection incidence of study group was lower than that of control group. Conclusion HBO treatment can improve the remission rate of brain edema and GCS scores, and it can reduce lung infection incidence in craniotomy for traumatic brain injury.

Objective: To observe the effect of Juebi capsule (JBC) on experimental prostatic hyperplasia. Methods: Experimental prostatic hyperplasia was induced by castration testicular nourmone in the mice and rats respectively and the isolated bladder trigone muscle of the rabbit was used for contraction inhibition. Results: For mice, JBC 10 20g/kg was administered intragastrically for 10 days; for rats, JBC 1 2g/kg was taken for 3 weeks. The results showed that JBC can significantly inhibite prostatic hyperplasia and decrease wet weight of the gland, DNA content and the activity of serum acid phosphatase. Otherwise, 0.25%, 0.50% and 0.75% water suspension of JBC also can inhibite the contraction induced by norepinephrine in isolated bladder trigone muscle of the rabbit. The inhibition rates were 29.17%, 41.72% and 62.29%.Conclusion: JBC can significantly inhibit experimental prostatic hyperplasia and decrease contraction of bladder trigone muscle induced by ? adrenoceptor agonist.

Objective To understand the distribution condition of resources of medicinal plant of Euodiae Fructus;To provide references for resource conservation and standardized plantation of Euodiae Fructus. Methods Literature search, interview survey and field survey were conducted to investigate the resource conditions of the main producing areas of Euodiae Fructus. Samples were collected and TKW of the medicinal plant was weighted. Results Currently, the main producing areas of Euodiae Fructus are provinces of Jiangxi, Guizhou, Hubei, Hunan and part of provinces and places of Guangxi, Anhui, Zhejiang, Shanxi, and Chongqing. Commercial Euodiae Fructus mainly comes from private investors. The wild resources of Euodiae Fructus are few. The TKW of the medicinal plant is within 5.34-45.62 g, with great differences. The national annual output of cultivated Euodiae Fructus is around 3500 t. The production and marketing is in balance. The price for Euodiae Fructus is relatively stable. Conclusion The plantation of Euodiae Fructus is dispersing, with small scale, low degree of standardization and intensification, and great quality differences. Standardized, large-scale, and industrialized plantation base should be established, and the assessment system for medicine quality should be perfected, with a purpose to ensure the qualified and stable production of Euodiae Fructus. Meanwhile, wild resource production should be enhanced to maintain the biological diversity and promote the sustainable development of Euodiae Fructus.

A chimeric protein called Wallerian degeneration slow (Wld(S)) was first discovered in a spontaneous mutant strain of mice that exhibited delayed Wallerian degeneration. This provides a useful tool in elucidating the mechanisms of axon degeneration. Over-expression of Wld(S) attenuates the axon degeneration that is associated with several neurodegenerative disease models, suggesting a new logic for developing a potential protective strategy. At molecular level, although Wld(S) is a fusion protein, the nicotinamide mononucleotide adenylyl transferase 1 (Nmnat1) is required and sufficient for the protective effects of Wld(S), indicating a critical role of NAD biosynthesis and perhaps energy metabolism in axon degeneration. These findings challenge the proposed model in which axon degeneration is operated by an active programmed process and thus may have important implication in understanding the mechanisms of neurodegeneration. In this review, we will summarize these recent findings and discuss their relevance to the mechanisms of axon degeneration.

OBJECTIVETo study the key processes of Fufang Kushen injection for technical upgrading.

METHODTotal alkaloids (sum of matrine, oxymatrine, sophoridine and oxysophoridine) and macrozamin were selected as quality evaluation markers. The key processes of percolation with acetic acid and discoloration with activated carbon were optimized by orthogonal experiment design, and process of purification with alcohol was investigated by single factor method.

RESULTThe optimal condition of percolation process is as follows: the medicinal materials are soaked for 9 h with 4 times water containing 0.8% acetic acid, then percolation starts at flow-rate of 5 mL x min(-1) x kg(-1) and adding 2 times 0.8% acetic acid solution is added at the same velocity. Purification process is that the concentrated solution is precipitated by 60%, 80% and 90% alcohol in turn. Discoloration process is that 6 activated carbon is added into the solution which is heated at 60 degrees C for 20 minutes.

CONCLUSIONThe optimal extraction process is not only simple, saving the industrial cycle, reducing the potential risk, but also decreasing the acetic acid amount to guarantee the acid-insoluble ash as well as the functional ingredients.
