OBJECTIVE:To evaluate the cost-effectiveness of3Chinese and western medicines in treating senile func?tional constipation.METHODS:186patients with senile functional constipation were randomly assigned to receive Forlax powder preparation for infusion,Liuweianxiao capsule and Buzhongyiqitang respectively,the therapeutic efficacies of the3groups were observed and the cost-effectiveness analysis were conducted12weeks after treatment.RESULTS:The cure rates for the3groups were77.6%,83.3%and85.5%,respectively;the costs for the3groups were963.52yuan,877.00yuan and850.12yuan,respectively;the ratio of cost to effectiveness were1241,1052and975,respectively;the incremental cost-effectiveness ratio of Group A and B were1435and1221as compared with Group C.CONCLUSION:Liuweianxiao capsule(Group B)was the preferred option for the treatment of senile functional constipation.

Functional dyspepsia is a common disease in clinical service.Its etiology and pathogenesis are related to a variety of factors,and among them,gastric motility and gastrointestinal motility dysfunction are major causes.At present,diagnosis of functional dyspepsia depends maindy on the complaint of patients and no gastric motility detection method or means are effective enough to complete the diagnosis objectively.The electrical bioimpedance technique extracts information of gastric electrical activity and mechanical movement base on the recngnition of electricity-mechanism compound system and studies complicated procedure of gastric electrical activity,mechanical contraction and gastric peristalsis.The electrical bio-impedance technique has shown a promising clinical application and development prospects.

Objective To verify the effect of activin A neutralizing antibody (AANA) on inhibition of hepatic fibrosis and mRNA expression of various cytokines. Methods Mouse hepatic fibrosis model was induced by CCl_4. Male Kun-ming mice were divided into 5 groups: normal control group,olive oil control group, CCl_4 model group, AANA group and antibody control group. The mRNA expressions of activin A, transfer growth factor (TGF)-?_1, platelet derived growth factor (PDGF) and tissue inhibitors of metalloproteinas (TIMP)-1 in liver tissue were determined by semiquantitative reverse transcription-polymerase chain reaction(RT-PCR) analysis. Results Compared with CCl_4 model group and antibody control group, the pathologic changes of hepatic fibrosis were ameliorated in AANA group, the mRNA expressions of activin A,TGF-?_1, PDGF and TIMP-1 were down-regulated in AANA group ( P

Objective To investigate the clinical and skeletal muscular pathological features of chronic progressive external ophthalmoplegia(CPEO).Methods The clinical and skeletal muscular pathological data of 6 patients with CPEO were analyzed retrospectively.Results All of the 6 patients onset were 4 to 18 years old.The first symptom was blepharoptosis.The clinical mainly manifestations were limited activity of eyeball,accompanied with limbs muscle fatigue,weakness and level elevatation of serum creatine kinase(CK).5 cases had myogenic changes in electromyography(EMG).The skeletal muscular pathological examination showed that the ragged red fibers(RRF)were scattered among the muscle fibers,and the deficient or absent of COX activity in many fibers.A few degenerating and necrotic fibers were observed in 4 cases.Lipid-drops were increased by oil red "O" stain in 3 cases.Electromicroscope showed that abnormal mitochondria increased in number and aggregated under sarcolemma or in cytoplasm.Crystalloid inclusion body could be observed.Conclusions The clinical mainly features of CPEO are external ophthalmoplegia and accompanied with limbs weakness.RRF and COX activity deficiency or absence according to skeletal muscle pathology can be suggest and support the diagnosis of CPEO.Gene sequencing based on skeletal muscle biopsy is necessary to make the final diagnosis of CPEO.

Objective:To develop an economical,simple and portable device for imitation of ship shock motion produced by non-contacting under water explosion.Methods:The device was developed based on aerodynamical principles and sensor detection technology,and was tested with animal experiments to verify its performance.The injuries caused by 4 grades of shock motions with different accelerations,duration and displacement were observed in 40 black rabbits(10 for each grade).Results:The device was safe and functionally stable,with a peak acceleration of 1 000 m/s~2,a shock duration of about 2 ms and a device displacement of 100 mm.The accelerations of 4 shock motion grades were significantly different and with good reproducibility.The damage to the rabbits were mainly haemorrhage of different extents in organs of pleuroperitoneal cavity,especially in the lungs,but no rupture of organs was found.The degree and involvement of damage had an increasing tendency with the increase of acceleration of shock motion.Conclusion:The device we developed can imitate the effects of ship shock motion.

Aim To prepare soluble global human C1 q and tumor necrosis factor related protein-2 in Escherichia coli. Methods Recombinant expression plasmid was transformed into strain BL21-codonplus (DE3),and the recombinant protein of Trx-gH2 was expressed by IPTG induction and then purified by Ni-NTA affinity and gel filtration chromatography.Results The purified recombinant Trx-gH2 was shown to be active under in vi-vo and in vitro assay conditions.Conclusion Active recombi-nant global hCTRP2 is efficiently prepared from Escherichia coli protein expression system.

Objective To study the features and risk factors of ischemic leukoaraiosis (LA) progression in elderly patients aged 80 years and over. Methods The 56 elderly patients with ischemic LA confirmed by MRI were enrolled in this study. The characteristics and risk factors of ischemic LA were comparatively analyzed between baseline and 3 years later by single and multi-variable logistic regression analysis. Results Ischemic LA progressed mostly in the subcortical white matter in elderly patients, especially the frontal lobes (progression of white matter lesion was present in 40% in the frontal lobes at baseline and 52% after 3 years), followed by the parietal lobes (35% at baseline and 36% after 3 years); Furthermore, previous high homocysteine (Hcy) and chronic bronchitis were risk factors of ischemic LA progression. Conclusions Ischemic LA progresses mostly in the subcortical white matter in the elderly, especially the frontal lobes; High Hcy and chronic bronchitis are risk factors of ischemic LA progression in elderly patients.

The recombinant plasmid of mChlL-18 prokaryotic expression was transformed into E.coli BL21(DE3) strain and then induced by IPTG at 37℃.After crushed and washed,the expressing inclusion bodies were thoroughly denatured with 6 mol/L guanidine hydrochloride.Then according to experiment design,the effects of rChlL-18 protein refolding yield at different densities were investigated by the systems of artificial chapercne at different densities.Experiment results indicate that there is a optimal condition on assiting rChIL-18 protein by using the artificial chaperone technique.The optimal condition can improve the refolding yield of rChIL-18 protein,and then the expressed product of fusion chicken IL-18 gene in E.coli has a relativity high bioactivity.

Objective To know the cognition,attitude and needs among middle-aged andaged women with urinary incontinence(UI) in communities. Methods A questionnaire survey wasconducted in 66 middle-aged and aged women with UI in two communities and the results were an-alyzed. Results Most patients lacked the knowledge of UI;UI had impact on their physical andmental heahh.Must patients wished to know about the treatment knowledge,and health education of med-ical staff was the most promising way.The mastering degree of knowledge about disease was not related tothe serious degree of disease and age,but was positively related to education degree and economic income.Conclusions We should publicize the knowledge about UI and provide health education and emotionalsupport to patients.And we should emphasize the training about UI among medical staff.
