Objective To research the risk of osteopo'rotic vertebral fractures with PKP after the PMMA injected location and dose of occurrence of vertebral refracture.Methods 78 cases of vertebral osteoporotic thoracolumbar vertebral compression fracture patients with PKP treatmentin were selected.According to position of postoperative PMMA in the vertebral body,they were divided into the side of the group of 35 patients and a median group of 43 patients.Compared two groups of patients before and after surgery,VAS,ODI score,the SI and Cobb angle and analyzed the PMMA leakage occur with the relationship of the amount of bone cement injected.Results There were significant differences in visual analogue pain scale(VAS),Oswestry disability index(ODI),sagittal index(SI) and Cobb angle of each group preoperatively versuspostoperatively (all P ＜ 0.05).No statistical difference was noted in the VAS,ODI,SI and Cobb angle between two groups preoperatively versus postoperatively(all P ＞ 0.05).PMMA injection volume between the the leakage group and the non-leakage patients had statistically significant difference (P ＜ 0.05).Conclusion PKP could obtain better clinical therapeutic effect in osteoporotic vertebral fractures treatment.Different PMMA positions had no significant influence on the therapeutic results.PMMA injected dose is a risk factor for bone cement leakage,which will increase the risk of vertebral fractures again.

Objective To conduct prospective randomized controlled clinical observation on patients with nasopharyngeal carcinoma under chemotherapy and radiotherapy using inhaling therapy with recombinant human interleukin 11,and the preventing and curing effect of recombinant human interleukin 11 on radiation-induced pharyngitis is evaluated.Methods 161 cases of newly diagnosed patients with head and neck cancer were selected under the principle of informed consent and these 161 cases were divided into the observation group (87 cases) and the control group (74 cases) based on randomization principle.In the observation group,when the dose reached 20Gy,then recombinant human interleukin-11 inhaling therapy was applied `ll the end of radiotherapy,for the control group,conventional treatment was applied in the event of radioactive throat.RTOG criteria were used during the observation in patients with the occurrence and treatment of radioactive pharyngitis.Results When compared with the control group,the average time for radioactivity to appear was prolonged,the severity decreased and the healing time was shortened in the observation group,those data were statistically significant.Conclusions Recombinant human interleukin-11 inhaling therapy can prevent and cure inhalation of radioactive pharyngitis and this therapy is better than conventional treatment.It's worthy of further study and clinical application.

Metebonomics is a branch of system biology,which,based on group index analysis, aims to analyze low molecular weight metabolites of the body both qualitatively and quantitatively through high flux and data processing.In recent years,the application of metabonomics to research of cardio-vascular pharmacology has been attracing more attention.This paper,by researching do mestic and overseas literature,summarizes the applications of metabonomics in the prevention and treatment of co mmon cardiovascular diseases such as hypertension,hyperlipide mia,atherosclerosis and myocardial ische mia.Related pharmacological researches targeted at patients,ani mal models and cell models clas-sified.Evidence for evaluation of effects and mechanis ms of drugs is provided by analyzing the patterns of change of metabolites in the progression of diseases.Finally,meaningful biomarkers are proposed.

Case teaching is one of the important means to improve teaching effect in the process of pharmacology teaching. According to the teaching object, teaching objectives and requirements to build one useful teaching case library about pharmacology, which can be used and shared for a long time, is the premise of case teaching in pharmacology. According to the actual situation of case teach-ing in our university, this study researched and explored the background of case library building, the basic principles of case compilation, the establishment of team, the teacher-led and the student-oriented processes of case building, and the process of sorting and summarizing cases in the case library build-ing, which promotes the reform in the pharmacology case teaching, improves teaching quality, and also provides a reference for other universities or schools and disciplines on teaching case library building.

The central of micturition and urinary continence in cats and humans is organized in similar manner. During the last decade, knowledge of neural pathways involved in micturition and continence has been greatly expanded. This review will summarize results from recent animal and human experiments.

Objective:To study Ca~(2 +) changes~( )in detrusor cell of the unstable bladder of rabbit~(,)s partial bladder outlet obstruction. Methods: Thirty male New Zealand White rabbits were divided into 2 groups randomly. In the experiment group the unstable bladder were confirmed by Urodynamics and the sham operated age-matched rabbits acted as the control group eight weeks after operetion. bladder smooth muscle cells were isolated by collagenase digestion. Intracellular Ca~(2+) levels in detrusor cell were observed by confocal laser scanning microscope (CLSM). Results: Intracellular Ca~(2+) concentration significantly increased in the experiment group (Ca~(2+) overload). Conclusion:It was a important pathogeny for the unstable bladder of partial bladder outlet obstruction that pathological changes of Ca~(2+) with the unstable bladder.

Objective: To provide a scientific method for the reasonable use of the drugs,and to use it as guidelines for clinical chemotherapy. Methods: Samples of test group were obtained from 38 cases of bladder cancer.which were cultivated with different medicines and then examined the inhibiting rate with MTT.The medicine with the highest inhibiting rate was selected to treat bladder cancer.30 cases of bladder cancer were treated with HCPT routinely as control group.The rate of tumor recurrence between two groups was compared. Results:The inhibiting rate on tumour cells was positively related to the concentration of drugs,the combined chemotherapy was superior to single drug.Statistic results showed significant difference between the test group and control group(P

Considerable advances have been made in the understanding of the cellular processes that result in contraction and relaxation of detrusor smooth muscle recently,particularly in the role and modulation of calcium.Several changes in these cellular mechanisms that impair normal function have been observed in detrusor muscle from patients with unstable bladders.Whether these changes represent primary causes of bladder dysfunction or whether they are secondary to bladder dysfunction remains to be determined.Nevertheless,the identification of specific cellular lesions in bladder dysfunction presents a novel approach to identification of drug targets and potential treatment modalities.

AIM: To investigate the effect of glycyrrhizin(GZ) and glycyrrhefinic acid(GA) on reducing the toxicity of Radix Aconiti Laterlis(RAL) and its mechanisms of action. METHODS: Radix Aconiti Laterlis(RAL),RAL with Radix Glycyrrhizae(RG),RAL with GZ,RAL with GA were boiled for 30 min,respectively.HPLC was used to measure the concentrations of aconitine and hypaconitine in the different decoctions.Meanwhile,the acute toxicity of the above decoctions was determined by oral and intraperitoneal administration in mice respectively. RESULTS: By oral administration,the acute toxicity of the decoctions of RG with RAL and GE with RAL was obviously lower than that of RAL.The acute toxicity of the decoction of GA with RAL was slightly reduced when compared with that of RAL.By intraperitoneal administration,the acute toxicity of GA with RAL was obviously higher than that of RAL.RG significantly restrained the dissolution of alkalines contained in RAL into the decoction.But GA and GZ increased the dissolution of the alkalines. CONCLUSION: By oral administration,RG could reduce the acute toxieity of RAL.Restraint on the dissolution of the toxic alkalines contained in RAL into the decoction may be in part the reasons.But GA and GZ are not the effective components reducing the dissolution of the toxic alkalines.They may combine with the toxic alkalines,postpone the absorption of the combined compounds through gastrointestinal tract,and reduce the acute toxicity of RAL by oral administration.
