Objective To compare of the effect of intravenous zoledronic acid and calcitonin on the elderly with osteoporotic intertrochanteric fractures.Methods From June 2009 to November 2012,610 patients with osteoporotic intertrochanteric fractures were treated with closed reduction and internal fixation.543 consecutive patients were grouped sequentially according to the admission time.From June 2009 to April 2011,control group (n=325)received calcitonin for osteoporosis (male 107,female 218,mean age 75.02±5.65 years).The number of Evans-Jensen type Ⅰ,Ⅱ,and Ⅲ type patients were 87,136,and 102,respectively.Average lumbar bone mineral density (BMD) and hip BMD were 0.737±0.08 g/cm2 and 0.725±0.05 g/cm2,respectively.From May 2011 to November 2012,218 patients (male 82,female 136,mean age 74.71±5.32 years) received zoledronic acid for osteoporosis.The number of Evans-Jensen type Ⅰ,Ⅱ,and Ⅲ type patient were 62,91 and 65,respectively.Average lumbar BMD and hip BMD were 0.738±0.05 g/cm2 and 0.722±0.06 g/cm2,respectively.All patients received once-yearly intravenous zoledronic acid in one week after operation.The BMD during hospitalization and one year after operation were compared between the two groups.Harris score and VAS score were applied to evaluate the function and pain degree of the operated hip joint.Results The average follow-up time were 12.8 months (range,5 to 22 months) in control group and 12.5 months (range,4 to 19 months) in treatment group.The average fracture union time,Harris score,VAS score were 14.25±1.38 weeks,68.88±5.71 points,and 0.36±0.55 points respectively in treatment group and 14.39± 1.12 weeks,69.47±4.60 points,and 0.33±0.48 points respectively in control group.There were no statistical differences between two groups in fracture union time,Harris score and VAS score.The average lumbar BMD and hip BMD were 0.76±0.06 g/cm2 and 0.75±0.04 g/cm2 in treatment group,which were 0.75±0.07 g/cm2 and 0.74± 0.07 g/cm2 in control group one year after operation,respectively.Compared with the baseline,the BMD of lumbar spine and hip one year after operation slightly increased without statistically significant difference in control group.The BMD increased significantly in treatment group.Conclusion Early administration of intravenous zoledronic acid does not influence bone healing and it could increase BMD one year after closed reduction and internal fixation.

It has been showed that there were obvious obstacle effects of Panax notoginseng replanting. Crop rotation was the main effective technique to overcome the obstacle. To find a reasonable crop rotation system for P. notoginseng, aqueous extracts from root, stem and leaf of P. notoginseng were analyzed for allelopathic effect on three maize varieties (which are often grown in regions where P. notoginseng grown). The main results were as follows: (1) Allelopathic effect of P. notoginseng stem and leaf extracts on the three other tested plants was stronger than that of root extracts; (2) Corn was more vulnerable to the effects of allelochemicals at seedling stage than at germination stage, and the corn root was more sensitive than aerial part to allelochemicals; (3) Lusan No. 3 and Yunrui No. 1 showed resistance to P. notoginseng allelopathy, with respective comprehensive sensitivity indexes (M3) of - 0.089 3 and -0.159 2, while Bainuo No. 1 is sensitive at M3 = -0.261 0. It then can be concluded that Lusan No. 3 and Yunrui No. 1 may be an alternative rotation plants for overcoming P. notoginseng continuous cropping obstacle.

Objective To study the effect of Cinepazide Maleate Injection on blood rheology of acute cerebral infarction patients. Methods 152 patients with cerebral infarction which attacked in 72 h after onset were separated into experimental group (n=88) and control group (n=64). 320 mg Cinepazide Maleate Injection was given to the experimental group and 20 mL Danshen Injection was given to control group, both by intravenous drip, once a day, for 14 d. The clinical efficacy and the changes of blood rheology were observed and compared in the 2 groups. Results The results of Chinese Stroke Scale (CSS) in the experimental group were significantly better than those in the control group (P<0.05), and the decrease in the parameters of blood rheology was much more obvious in the experimental group than in the control group (P<0.05) 2 weeks later. The excellent rate was 62.5% in the experimental group, which was higher than 35.9% in the control group significantly (P<0.05). Conclusion The Cinepazide Maleate Injection is effective in the treatment of acute cerebral infarction and can reduce the blood viscosity.

· ATM:To analyze bacterial spectrum and drug sensitivity in conjunctival sac of cataract patients of Kazak.
· METHODS:A total of 538 cases of conjunctival sac secretion in cataract patients of Kazak were collected.The samples were cultured and their sensibilities to antibiotics were tested.
· RESULTS: The bacterial culture was positive in 214 cases.The positive rate was 39.8%. The variety of pathogenic bacteria were mainly made up of gram positive cocci ( 88.3%), and most of them were Staphylococcus epidermidis ( 66.4%), followed by Micrococcus(9.8%).Sex had no effect on conjunctival bacteria rate in the cataract patients of Kazak, while age, place of residence had an effect on camier rate. The camier rate of conjunctival bacteria was significantly higher in people over 60 years old than that in people with age between 40 to 59 years old.And the people from city had a significant lower bacteria positive rate than those from countryside and pastoral. Most of grams were sensitive to Vancomycin, Teicoplanin, Rifampicin, Duly cloth mildew mutual and Amikacin, the tolerance was less than 20%, and they usually had higher tolerance to Penicillin, Erythromycin, Tetracycline and Chloramphenicol (>70%) .
·CONCLUSlON:Gram positivecocci is the most common bacteria in conjunctival sac in cataract patients of Kazak. Staphylococcus epidermidis was most common, followed by Micrococcus.The germ-carrying rate of conjunctival SAC in Kazakh population is associated with the patient’s age and area of residence.The clinical use of antibacterial drugs should be strictly grasp the indications, to reduce the incidence of bacterial resistance.

OBJECTIVETo investigate the time trends of cancer mortality among residents in Kaifeng county, Henan province.

METHODSData on cancer mortality from the vital registration system in Kaifeng county from 1988 to 2005 was analyzed. A total of 9543 death records (5974 males and 3567 females) due to malignant tumors were studied. A two-year-period age-specified standardized mortality rates were directly adjusted by the world standard population, and the annual percentage change (APC) of mortality were estimated by a linear logarithm regression.

RESULTSThe crude cancer death rate for male was 95.09/100,000 and its age-standardized death rate was 117.41/100,000. While, the crude cancer death rate for female was 59.13/100,000 and the age-standardized death rate was 57.15/100,000. There was a significant growth tread for lung cancer (APC: 6.54%), liver cancer (5.07%) in males and breast cancer (7.04%) in females in the groups aged over 18. On the contrary, the decreasing treads for esophageal cancer in both of sexes (-7.09%, -13.53%) were also observed in this study. Meanwhile, there was no other significant changes in the trend, either in the tumor sites or mortality, was observed.

CONCLUSIONIn the past two decades, there has been a significant increasing trend for cancer mortality in Kaifeng county, of Henan Province. Hence, it is necessary to enhance epidemiological survey to identify risk factors at the earlier stages.

This research aimed at studying the effects of irrigation and rhizome length on the survival of ratio, yield and quality of Glycyrrhiza uralensis in wild tending condition. Employed the split-block design to carry out the field experiment, sampled with the quadrat method to measured the relative growth indexes and to estimate the yield, used the HPLC (high performance liquid chromatog- raphy ) method to measure the glycyrrhizin in the rhizome and adventitious root of the G. uralensis in this study. The quantity of the adventitious roots and the survival ratio were increased significantly as the length of the rhizome increased (P < 0.01), but the length of the rhizome had no remarkable effect on the content of glycyrrhizin. The average content of the glycyrrhizin in the adventitious root and rhizome could reach 3.03% and 2.12% after 3-year wild tending, respectively, and this results indicated that the quality of the glycyrrhiza using this method was much better than that from cultured glycyrrhiza with the reproducing method of seeding. so using the rhizome as reproductive material to produce the glycyrrhiza under the wild tending condition could get the high quality glycyrrhiza quick- ly and steadily, this phenomenon could be explained by the Hypothesis of synthetic inertia of the medicinal components from the wild material of G. uralensis. But the maximum yield with this method was just more than 945 kg x hm(-2) in this study. So the further work of how to increase the yield in the practical application with the method found in this study need to be done in the next research.
