OBJECTIVETo confirm the amount of fertilizer and the ration of fertilizer.

METHODThrough the experiment of planting Salvia miltiorrhiza in pot and in field were carried out.

RESULTWhen N:P = 1:1, The production was 1.8 times more than the contrast group in plotting experiment, and in field the production of the highest fertilizer plot were 2.5 times more than the contrast and the higher and high fertilizer plot is 2.25 and 1.2 times respective were than those in the contrast group.

CONCLUSIONThe proper ration of nitrogenous fertilizer and phosphorous fertilizer is 1:1. Nitrogen shows negative effects to the accumulation of tanshinon IIA, the more the nitrogen ous fertilizer, The less the content of tanshinon IIA. In contrast, phosphor ous fertilizer shows good effects on the accumulation of tanshinon IIA. Phosphorous fertilizer could alleviate the decline of the content of tanshinon IIA by using nitrogenous fertilizer. The accumulation peak of the tanshinon IIA emerge in the period of 150 d.

AIMTo study the clinical effects of a disposable circumcision device in treatment of male patients of different ages with either phimosis or excess foreskin.

METHODSOne thousand two hundred patients between the age of 5 and 95 years underwent circumcision using this procedure in the 2-year period between October 2005 and September 2007. Of these cases, 904 had excess foreskin and 296 were cases of phimosis.

RESULTSIn 96.33% of the cases the incision healed, leaving a minimal amount of the inner foreskin with no scarring and producing good cosmetic results. There were no incidents of device dislocation or damage to the frenulum. The average operative time was 2.5 min for excess foreskin, and 3.5 min for phimosis. During the 7 days of wearing the device, mild to moderate edema occurred in 10.08% of cases with excess foreskin and in 2.58% of those with phimosis. Edema in the frenulum was seen in 1.67% of patients, and only 0.67% had an infection of the incision. A total of 86.25% of patients reported pain due to penile erection. After removal of the device, 0.58% of the cases had minimal bleeding around the incision, and 2.42% had wound dehiscence.

CONCLUSIONThe new device can be applied to an overwhelming majority of patients with phimosis and excess foreskin. This technique is relatively simple to perform, and patients who underwent this surgery had very few complications. Antibiotics were not required and patients reported less pain than those who were circumcised using conventional methods. Circumcision with this device requires minimal tissue manipulation, and is quicker and safer than circumcision using conventional techniques.

OBJECTIVETo study the relationship between plant growth and accumulation of active ingredients in Salvia miltiorrhiza.

METHODTransplants of S. miltiorrhiza were sampled at 20 day intervals. At each stage, the growth of seedling and root system was recorded and the contents of tanshinone II (A) and salvia acid were measured.

RESULT AND CONCLUSIONThis study showed that the rapid growth stage of the root system lags behind that of the seedling system, but the growing period of root system lasts longer. The quantitative change of roots reveals a double "S" curve; two rapid growth stages emerge during 30 - 70 days and 140 - 200 days after the seedlings were transplanted. The content of salvia acid reaches the highest level during 140 - 180 days, whereas the content of tanshinone peaks during 100 - 120 days.

Objective To demonstrate the current prevalence and treatment status of diabetes mellitus (DM) among inpatients with acute coronary syndrome (ACS) in China. Methods Sixty-four hospitals, including 32 secondary hospitals and 32 tertiary hospitals were selected for baseline survey. Fifty inpatients diagnosed with ACS were recruited consecutively from hospitals participated in this study. This paper focused on the prevalence and treatment status of DM among inpatients with ACS. Results (1)Clinical data of 3223 inpatients (average age 65±11 ) with ACS were collected during baseline survey,including 2183(67.7%) males and 1040(32.3%) females. Among them,39.8% were diagnosed as ST-segment elevation myocardial infarction ( MI), 9.2% as non-ST-segment elevation MI, 51.0% as unstable angina,and 27.1% with ACS history. (2) DM was found in 22.6% ACS patients. The prevalence rate of DM was higher in female (26.3%) patients than that in males (20.8%). The rate of DM was the highest(28.0%) in northeast area and lowest (17.7%) in southwest among 7 geographic districts (north, east,south,central,northeast,northwest and southwest parts of the country). Significant difference was observed among these areas. (3) Rate of awareness on DM was 73.1% among patients with DM, with significant differences among various areas. Treatment rate was 62.1% among patients with DM, with the highest(88.6%) seen in northwest and the lowest (78.4%) in central part of China. (4) Rates of prevalence(27.1%), awareness (82.3%) and treatment (86.7%) of DM were higher in recurrent ACS patients than in those without ACS history, Conclusion Nearly one-forth of the ACS inpatients were having DM, and 15% of the patients with known DM were not on anti-diabetic treatment. It is essential to pay more attention on the treatment of DM for the purpose of secondary prevention on cardiovascular disease.

OBJECTIVETo provide theoretic warrant and technical reference for Salvia miltiorrhizr standardization planting, by carrying out various systemic studies such as observation of seeds configuration fabric, idiosyncrasy of water absorption and groping germinating conditions.

METHODIn the study of configuration fabric, seeds were observed and taken photos by scanning electronic microscope, and heft method was used for measuring changes of water absorption velocity and dehydration velocity. Seeds germination conditions were probed into under the national test regulations for crop seeds and related prescription from international standards.

RESULT(1) There was a layer of slime about 10-20 microm thickness covering epicarp of Danshen seeds. The slime formed as diamond meshwork (reseau) and the weight of it was 8%-10% of total seeds weight. (2) The speed of water absorption of seeds was extremely rapid. The weight of seeds could increase above 10 times as original while the dehydration velocity was quite low. (3) The optimal temperature for the seeds germination is around 25 degrees C, and the germination rate of the new seeds gained yearly was above 75%, but the rate would decrease sharply as years went by. It was also found that the seeds germination power and exponent of vigor were quite high under the temperature transformation between 23 degrees C, 28 degrees C. Such treatments as pre-cool, PEG treatment and infusing with GA3 could increase the rate of seeds germination capacity obviously.
