In 2010, Chinese Pharmacopoeia Committee officially enacted Chinese Pharmacopoeia (2010 edition). The Volume 1 of the pharmacopoeia is comprised of the medicinal materials and the decoction pieces, the essential oils and extracts of medicinal plants, prescription preparations and single preparation, etc., which not only provides Latin names of Chinese medicinal materials, also provided Latin names of the original medicinal plants to effectively control the quality of Chinese medicinal materials. In order to raise awareness of correctly citation and maintain the authority and standardization of Chinese Pharmacopoeia, this paper briefly describes abbreviations rules of authors' name of plant scientific name according to the 'International Code of Botanical Nomenclature, ICBN'. Through comparing with the rules of ICBN, 'Flora of China' (Chinese edition and English edition), and authority international plant catalogue databases, the authors made statistic and analysis of the non-standard cited authors' names phenomena of the original plant scientific names recorded in the Chinese Pharmacopoeia (2010 edition), and the revision suggestions are proposed.

AIM: To observe the efficacy of high concentrations of sodium hyaluronate ( 3g/L SH ) for moderate to severe dry eye.
METHODS: Forty moderate to severe dry eye patients were included in the study according to the diagnosis criteria and randomized into two groups. The patients of the trial group received topical administration of high concentration sodium hyaluronate (3g/L), and those of the control group received sodium hyaluronate ( 1g/L ) plus recombinant human epidermal growth factor. The dry eye symptom scores, ocular surface disease index ( OSDI) scores, tear film break-up time ( BUT) , SchirmerⅠ test and corneal fluorescein staining score were evaluated. All the indexes were compared between the two groups 2wk before and after treatment.
RESULTS: There were no significant differences of the indicators between the two groups before treatment. After 2wk treatment, the differences were statistically significant compared to former except for the SchirmerⅠtest. Compared with the control group, the symptom scores and the OSDI scores were lowered. No significant differences were found in the other indicators between these two groups.
CONCLUSION: Topical usage of highconcentrations of sodium hyaluronate (3g/L) is beneficial for remitting the ocular symptoms in moderate to severe dry eyes, and also improve the quality of life of patients.

Chronic pain is a common clinical disease,which brings great burden to the patients.However,the pathogenesis underlying of chronic pain is complicated,which is affected by many factors,such as physiology,psychology and society.Therefore,the treatment of chronic pain has been a problem in clinical practice.Considering its complexity,a single way of treatment usually could not reach satisfactory results,so combination therapy is often used to treat chronic pain at present.The combination therapy includes pharmacological treatment,psychological approaches,interventional treatment,self management and so on.The treatment plans are distinct for different types of chronic pain,even the individual patients with the same kind of pain.The emergence of interdisciplinary rehabilitation programs shed light upon the treatment of chronic pain recent years.This paper reviewed the research on chronic pain treatment,in order to provide theoretical basis for clinical practice.

To investigate the effect of losartan on the axis of prolylcarboxypeptidase (PRCP)--kallikrein of the two-kidney, one-clipped (2K1C) hypertensives rats, and explore the novel protection mechanism of losartan on the kidney. Sprague-Dawley (SD) rats were used to develop the 2K1C hypertensive rats. Then, the rats were treated with prazosin (5 mg x kg(-1) x d(-1)) or losartan (5, 15 and 45 mg x kg(-1) x d(-1)) or vehicle, separately. At the same time, the blood pressures were observed. After treated for four weeks, the ratio of right kidney weight and body weight, the change of glomerular morphology, and K+, Na+, creatinine and blood urea nitrogen (BUN) of the serum were used for evaluation of kidney. The expressions of PRCP mRNA in the kidneys were determined by RT-PCR. The protein levels of PRCP, tissue kallikrein, plasma kallikrein, TGF-beta1 in kidney or plasma were measured by Western blotting. Results showed that the changes of body weight and kidney weight ratio, glomerular fibrosis degree and the biochemistrical index of serum induced by hypertension were relieved when the hypertensive rats treated with losartan for four weeks. Meanwhile, treatment of losartan also significantly decreased expression of TGF-beta1 and increased expressions of PRCP, plasma kallikrein and tissue kallikrein. The protective effects of losartan on the kidney of 2K1C hypertensive rats are activation of the axis of PRCP-kallikrein and reducing the expression of TGF-beta1.

Objective To compare the myocardial protective effect of hyperpolarized cardioplegic arrest with pinacidil against that of depolarized hyperkalemic arrest during cardiopulmonary bypass Methods Eighteen healthy mongrel dogs of both sexes weighing 10 15kg were divided into three groups of six each, according to the cardioplegic solution infused into aortic root after aortic cross clamp was applied; group A received 4℃ standard St Thomas solution (K +16mmol/L); group B 37℃ St Thomas solution (K +5mmol/L) containing pinacidil (50?mol/L) mixed with blood (the ratio was 1:1);group C 4℃St Thomas solution (K + 5mmol/L) containing pinacidil(50?mol/L) mixed with blood (1∶1) The global ischemic time was 60min followed by 30min reperfusion Myocardial tissue was taken before and 30min, 60min after aortic cross clamping and 30min after reperfusion for determination of myocardial content of adenine nucleotide and MDA and ultrastructure examination with electron microscope Hemodynamics (BP,CVP,PCWP,CO,CI and LVSW) was also measured before aortic cross clamping and 15,30min after declamping Results Significant ischemic and reperfusion damages were found in group A, while there were only mild damages in group B and C Hemodynamics recovery after aortic declamping was significantly better in group C than that in group A and B Conclusions Myocardial protective effect of hyperpolarized arrest produced by blood cardioplegic solution containing pinacidil is superior to that of traditional depolarized hyperkalemic arrest and hypothermic hyperpolarized cardioplegia is better than normothermic

Objective To compare the myocardial protective effect of pinacidil-induced hyperpolarized and hyperkalemic depolarized cardiac arrest on isolated rabbit heart under different temperature. Methods Forty-eight rabbits of both sexes weighing 2.0-2.5 kg were sacrificed by a knock on the head. Their hearts were excised and perfused in a Langendorff apparatus with an oxygenated Krebs-Hensleit buffer (KHB)(37℃). The study was divided into six groups: A normothermic hyperkalemic cardioplegia; B normothermic hyperkalemic blood cardioplegia; C hypothermic hyperkalemic cardioplegia; D hypothermia hyperkalemic blood cardioplegia; E normothermic hyperpolarizing blood cardioplegia; F hypothermic hyperpolarizing blood cardioplegia. Three pieces of myocardial tissue were obtained from apex of left ventricle at the end of the study for determination of myocardial adenine nucleotide and lipid peroxide content and microscopic examination. The following were recorded : (1) cardiac arrest time: the time from perfusion with cardioplegic solution to the beginning of cardiac arrest. (2) heart beat recovery time ;the time from reperfusion with KHB to the beginning of normal heart beat. (3) changes in HR, left ventricle developed pressure and myocardial contractility before and after cardiac arrest. Results The cardiac arrest time was longer and the time for the heart to restart was shorter in the two hyperpolarizing blood cardioplegia groups (group E and F) than that in the other 4 groups. No arrhythmia occurred in group E and F. Left ventricle developed pressure(LVDP) and left ventricle contractility recovered quickly after reperfusion with KHB was started and were restored to the pre-ischemia level after 20 min in group E and F. The levels of ATP, TAN and EC were higher and the MDA level was lower in group E and F than those in the other 4 groups. Myocardial structure was less injuried in group E and F. Conclusion The myocardial protection effect of hyperpolarizing blood cardioplegia with pinacidil is superior to traditional hyperkalemic depolarizing cardioplegia.
