Seventy two kinds of drugs were irradiated by neutron (1?1013cm-2) and ?-ray (1?104R) to evalute their radioactivity, potency, content and some other physicohe-mical properties at intervals of 48 hrs and 3 months after exposure. LD50 of 36 kinds of drugs were measured and main pharmacological effect of 40 kinds of drugs were observed .The induced radioactivities of drugs, the 5% glucose in normal saline and the injection KC1 were found to be about 1? 10-1 ?Ci/ml, the rest were either about equal to or less than 1?10-2 ?Ci/ml(g.).No radiative effdcts were observed among these drugs with the exception of VitB12, ether and 0.1% citric acid The content of VitB12 was dropped after the radiation. Its decrease was found to be proportional to the dose of radiation.Slight changes in color and content were found in 10 of these drugs after radiation, but their extents were within the normal ranges according to the Chinese Pharmacopoeia.

Carcinoma of pancreas is the most common primar y pancreatic malignancy. Symptoms usually are nonspecific and include abdominal pain, jaundice, loss of appetite, weight loss, nausea, and vomiting. CT usually demonstrates a mass with ill-defined margins but also solid components and dil atation of the main pancreatic duct. This tumor is usually smaller and virtuall y never contains calcification. Following contrast material administration,all masses were enhanced less than the surrounding pancreas. Tumors were oval, rou nd or lobular,and is almost always locally invasive. These features can be used to differentiate carcinoma of pancreas from other pancreatic tumors.

ObjectiveTo investigate the influence factors of operative effect in complex acetabular fracture. MethodsSixty-seven patients with complex acetabular fractures were selected. All patients were used surgical treatment,the clinical curative effect by Merle d'Aubigne-Postel hip scoring function to evaluate,set the age,sex, operation time,operative approach,the quality of fracture reduction,complex dislocation of the hip fracture and type of complex acetabular fractures with comparative index,the results were statistically analyzed. ResultsPatients were followed up for 6-24 months,the mean time was 14.6 months. Univariate analysis showed that the fine efficacy of surgery taken in no more than 2 weeks [84.0％ (42/50)]was better than more than 2 weeks [64.7％ ( 11/17 )](P ＜ 0.05 ). The high-quality of reduction [86.4％ ( 19/22 )]was better than low-quality of reduction [44.4％ (4/9)] (P ＜ 0.01 ). The compare of age,sex,operative approach,complex dislocation of the hip fracture were no statistically different (P ＞0.05).Complex acetabular fractures of T-shaped fracture healing rate was 85.7％ (12/14),the excellent rate was significantly higher than posterior column with posterior wall fractures[77.8％ (7/9)],transverse with posterior wall fractures [75.0％ (15/20)], anterior column with half of transverse fractures [66.7％ (2/3)],double-column fractures[71.4％ (15/21)],the results were statistically different. Conclusion The necessary conditions for ensuring fracture prognosis is the quality of reduction,timing of surgery,and type of fracture.

OBJECTIVE： To confirm the efficacy and safety of latanoprost in treating glaucoma.METHODS： In a double blind， randomized control clinical trial， we compared the efficacy and adverse drug reactions of once daily topically applied 0.005％ latanoprost with those of twice daily 0.5％ timolol for 12 weeks in patients with open angle glaucoma or ocular hypertension.RESULTS： The study included 46 patients（22 pts.randomized to latanoprost treatment， 24 pts.to timolol） ， 46 patients remained at the end of the study.Comparing with baseline diurnal intraocular pressure（IOP） ， the IOP reduction（mean±standard deviation） achieved with latanoprost（7.86±2.39） mmHg， （31.1％， P<0.001），and timolol（6.24±2.58）mmHg （24.9%，P<0.001），the difference between the two groups（1.62mmHg） being significant（P<0.01）. Two patients treated with latanoprost had foreign body sensation. No other ocular and systemic adverse reactions related to the two drugs were found. CONCLUSION: The results of this study demonstrated that 0.005% latanoprost applied once daily is well tolerated and more effective in reducing IOP than 0.5% timolol applied twice daily. Thus, latanoprost has the potential for becoming one of the ideal antiglaucoma drugs.

Aim To investigate the effects of osthol on bone marrow stromal stem cells in vitro under the con-ditions of the ability to differentiate into osteoblasts and the case of proliferation. Methods The rat bone marrow sample was obtained,and the all bone marrow cell culture methods were used to separate and collect the stratum of mononuclear cells. The cells were cultured in DMEM containing 10% fetal bovine serum. Three days later the culture medium was changed for the first time. Nine days later,serial subcultivation proceeded. The final concentration of osthol was 1 ? 10 -4,1 ? 10 -5,1 ? 10 -6,1 ? 10 -7 mol?L -1 respectively. MTT method was adopted in proliferation analysis. Under the induced condition,the Alkaline phosphatase activity, calcium salt sediment yield and osteocalcin were meas-ured on 4th,8th,12th,16th day. On the fifteenth day,his-tochemistry dyeing proceeded for calcified tubercle. Total RNA was isolated and the gene expression of bFGF, IGF-1,Osterix and Runx-2 was investigated by RT-Real Time PCR. Results The BMSCs proliferation was refrained by osthol dose-dependently. But it evidently led to osteogenesis. The ALP activity,calcium salt sediment yield and osteocalcin were raised,and calcified tubercle amount was increased. Besides,it also could enhance the mRNA level of bFGF,IGF-1,Osterix and Runx-2. Conclusion The osthol with final concentra-tion of 1 ? 10 -5 mol?L -1 can markedly promote BM-SCs differentiation to osteogenesis. which proves osthol is an active constituent of the traditional Chinese medi-cine Common Cnidium Fruit.

A total of 216 patients with type 2 diabetes mellitus and their family members were randomly divided into intervention and control groups.On the basis of conventional drug therapy,for intervention group,the patients and their family members were instructed to participate in health education activities and self-monitoring guidance.For control group,only patients were required to participate.The intervention continued for 12 months.Compared with control group,the intervention group significantly improved their living habits and the level of knowledge structure.The levels of low-density lipoprotein (LDL),2 h postprandial blood glucose and glycated hemoglobin improved after intervening.And there were statistically significant differences (P ＜ 0.05).The family members of patients had more knowledge of identifying and dealing with low blood sugar while their knowledge of medication and regular monitoring was significantly better than that of control group.And there were statistically significant differences (P ＜ 0.05).Family-involved diabetic management is conducive for forming diabetic self-management behaviors.
