Three new points of view were reported in this study:1.Found out the distribution of KaschinBeck disease (KBD) in Tibet,the complexity of bone disease composition,and the types of osteopathy coexisted which need to be identified;2.The clinical symptoms of KBD in Tibet were significantly different from those in other areas of our country;3.The new clinical subtypes of KBD were found in Tibet,which had humeral shortness and short stature,but with normal hands and feet.This discovery made us understand KBD more profoundly and comprehensively,and promoted the research and prevention work of KBD.

0.05). The positive rates of PDGF and PDGFR in the HCC patients with the tumor emboli of portal vein and/or biliary duct were 76.9% and 76.9%, respectively, which were significantly higher than those(25.0% and 16.7%, respectively) in the ones without(P

OBJECTIVE:To investigate the complexation of clonazepam with hydroxypropyl-?-cyclodextrin(HP-?-CD)in aqueous solutions.METHODS:The complexation of clonazepam with(HP-?-CD),the inclusion molar ratio of host and guest molecules and thermodynamic parameters were detected using phase solubility method,equimolar series method,UV absorption spectroscopy etc.RESULTS:The solubility of clonazepam increased linearly with the increase of(HP-?-CD)level in aqueous solutions at different temperatures(25℃,35℃and45℃)and in buffers at different pH values(4.0,6.0and7.0),the phase solubility diagram was classified as type AL.CONCLUSIONS:Under the above research condition,the incl_ usion complexes of clonazepam with(HP-?-CD)can be formed spontaneously at a molar ratio of1∶1.

Objective To explore the risk factors of esophageal cancer and these factors' interaction Methods 472 new diagnosed cases of esophageal cancer in 2004—2005 and 472 controls were investigated by case-control study. Etiological fractions and interactions between family history of esophageal cancer and other risk factors of esophageal cancer were analyzed. Results The significant independent risk factors included taking hot-meal, preferring pickled-vegetables, preferring dry-rigidity-food, being irritable, drinking polluted-water perennially, family history of esophageal cancer and drinking alcohol a great deal. The etiologic fractions attributable to interaction were 0.855, 0.758, 0.683, 0.464, 0.459, 0.343 and 0.108 respectively. The synergy indexes of family history of esophageal cancer with taking hot-meal and with preferring dry-rigidity-food were both 0.86. Concludes The interactions between family history of esophageal cancer and ill life-behavior-style or drinking polluted-water perennially were particularly significant in the development of esophageal cancer in Dongping County.

Objective To explore the technique of T-tube replacement after choledochoscopy.Methods Choledochoscopy was performed in 256 cases,replacement of T-tube was conducted by direct insertion technique in 85 cases(Group A),and by a wire-guide technique in 171 cases(Group B).Results Three cases of T-tube replacement were unsuccessful in group A,in one case of which,the T-tube was misguided into the bowel and the patient recovered after conservative treatment following the withdrawal of T-tube.In group B,all the T-tube replacements were conducted successfully with the wire-guide technique.Conclusions Replacement of T-tube is facilitated by the wire-guide technique.

OBJECTIVE: To study the development strategy of clinical pharmacy under the condition of New Medical Reform in China. METHODS: The status quo and obstacle factors of clinical pharmacy were analyzed to probe into the chance for clinical pharmacy in China brought out by New Medical Reform. RESULTS: The reimbursement mechanism reform of state hospitals, National Essential Drug System, medical insurance system, charge for pharmaceutical care system and the construction of primary hospitals and public health service provide development opportunities of clinical pharmacy. CONCLUSION: The development strategy of clinical pharmacy should be associated with New Medical Reform and relevant policy, laws and regulations of clinical pharmacy should be improved. Great importance should be attached to exploring the training system of clinical pharmacists and approaches of clinical pharmacy.

OBJECTIVE:To compare the substitution between the gray relation analysis( GRA) and the orthogonal design(OD) in data processing. METHODS:Take the four factors including the molar ration of drug and cyclodextrins,the agitating time and speed,and the temperature of complexation that influenced on loaded dosage of ursolic acid complex as example to analysis with 2 kinds of methods. RESULT:The result of analysis was similar by 2 kinds of methods,the molar ration of drug and the temperature of complexation were the major influence factors. CONCLUSION:When the data cannot fit to the analysis of range of OD,GRA can be used to it.

Objective To observe the individualized insertion choice in treatment of upper cervical injury with posterior atlantoaxial short-segmental pedicle screws or lateral mass screws and the relevant clinical outcome.Methods A total of 23 cases of upper cervical injuries received skull traction preoperatively.Individual surgery plan including internal fixation using pedicle screws or lateral mass screws as well as diameter,length,entry point,direction,and angle of screws was determined according to their atlantoaxial CT scan and three-dimensional reconstruction results.Results Six cases of Frankel grade C and eight of grade D were all recovered to grade E after operation.All cases presented rigid fixation and bony fusion in the follow-up of 6 to 36 months.Besides,screws were removed after bony fusion for three young cases and one case with left atlas pedicle screws emerged laterally out of cortex.Clinical outcome was all satisfactory.Conclusion Individualized posterior atlantoaxial fixation using pedicle screws or lateral mass screws is an effective way to treat upper cervical injury and gains advantages of stable threedimensional structures,short fixation segments,and few postoperative complications.

Objective To assess the effect of intravenous infusion of octreotide in prevention of pancreatic fistula after pancreaticoduodenectomy. Methods The clinical data of 74 cases of pancreaticoduodenectomy performed from January 1996 to July 2003 were retrospectively reviewed. These included 36 cases in control group in which octreotide was not adminstered,and 38 cases in octreotide group in which octreotide was administered by intravenous infusion of 0.5?g/( kg?h) for 12 hours per day from the operative day to postoperative day 7. The study parameters included clinical manifestation,drainage from peritioned cavity and the amount of drainage of pancreatic fluid. Results The drainage of pancreatic fluid at postoperative day 1,3,5 the in octreotide group was significantly less than those in the control group,the average hospital stay and the incidence of pancreatic fistula were significantly lower than those in the control group,and the drainage of pancreatic fluid was significantly increased after the withdrawal of octreotide in the octreotide group. Conclusions Intravenous infusion of octreotide can significantly lower the incidence of pancreatic fistula after pancreaticoduodenectomy.
