Objective To investigate the status of urogenital Ureaplasma urealyticum (Uu) infection and their drug tolerance in our area,so as to guide rational administration for the clinic.Methods Mycoplasma culture and drug susceptibility test were performed for 771 patients with urogenital infaction. The culture,identification and drug resistance of mycoplasma were carried out with one complex mycoplasma kit.Results The positive rate of Uu was 49.9%. The proportional percentage of males was 12.5% and the Uu positive rate was 22.3%,for females,the proportional percentage and Uu positive rate was 87.5% and 60.6% respectively. The population aged 21-40 was susceptible to Uu infection. The most sensitive antibioties to Uu was clindamycin (95.12%),followed by doxycycline (87.57%) and roxithromycin (86.24%).Conclusion The difference of Uu drug sensitivty was significant in different areas. So it is necessary to select antibioties by drug sensitivity. Clindamycin,doxycycline and roxithromycin may are used as preferred antibioties in treating Uu infection in our area. The drug-resistance status of spectinomycin and lincomycin was serious.

OBJECTIVE To explore the situation of bacteriological examination in every clinical department,know distribution and drug resistance of pathogenic bacteria,and offer the help about diagnosis and reasonable using antibiotics.METHODS Using the Microscan A/S-4 to identify the microbes and microbial sensitivity tests according to pathogens from more than twenties clinical departments between 2004 and 2005.RESULTS The clinical delivering rate was low,and samples were dispersive.The samples mostly were sputum,pus,urine and blood,and their rate was 52.15%.The first three pathogenic bacteria were totally 13 kinds of species in all kinds of departments.The main pathogenic bacteria in the internal medicine such as in the department of respiration,department of gerontology,department of endocrinology and so on were mostly Klebsiella pneumonia and Escherichia coli.The main pathogenic bacteria in department of neurosurgery,ICU,department of burn and department of trauma were mostly Pseudomonas aeruginosa,Acinetobacter baumannii/haemolyticus,Enterobacter cloacae and Staphylococcus aureus,These bacteria might lead to nosocomial infections in our hospital too.Their rate was 52% and drug-resistance was serious.A.baumannii/haemolyticus and E.cloacae were only sensitive to imipenem.P.aeruginosa was most sensitive to piperacillin/tazobactem and next to ceftazidime,amikacin and ciprofloxacin.CONCLUSIONS There are the serious phenomena that P.aeruginosa,A.baumannii/haemolyticus and E.cloacae are highly resistant to many antibiotics.We will much more attend and study it.The clinics must attend it and improve the delivering rates of cultured sample.

Interest in learning can not only stimulate students' enthusiasm for learning, but also directly affect the quality of higher education. In this paper, the questionnaire of the related factors of college students' interest was designed to carry out micro-system engineering research. The factors as-sociated with college students' interest in learning and their complex relationships were investigated by using methods of systems science and systems engineering. The results shows that the students who can actively participate in after-school learning discussions , feel good in lectures and have clear learning objectives, are interested in learning. And at the same time, the teacher's influence and his active guidance in classroom teaching will raise students' interest in learning. This study provides a more comprehensive basis and clues to improve students' interest in learning and education reform.

According to the theory of microscopic system reform in higher education, a total of 927 college students of different majors from Beijing University of Chinese Medicine were investigated by using SIMPP method. It indicated that through promoting the study of self-prepared, learning state and learning effect, students can enhance their learning ability of the admission acceptance. From the perspective of teachers, the students' self-study ability can be fully mobilized using individual person-alized teaching method. Then, the initiative of university education in the teaching and learning can be improved. Ultimately, the efficiency of student learning can be improved.

Objective To study the biodistribution of 131 I-2'-deoxy-1-β-D-arabinofuranosy1-5-iodouracil (FIAU) in the rat middle cerebral artery occlusion model and the expression of thymidine kinase (TK) gene in brain tissue after gene-modified stem cell transplantation,and thus evaluate the possibility of further noninvasive monitoring of stem cell transplantation therapy in cerebral infarction.Methods Adenovirus recombinant Ad5-TK-intemal ribosome entry site-brain derived heurotrophic factor-enhanced green florecent protein(IRES-BDNF-EGFP) carrying TK-IRES-BDNF gene was prepared.Cerebral infarction model was established in rats by intraluminal middle cerebral artery occlusion with nylon monofilament.Gene modified bone marrow mesenchymal stem cells were transplanted via intraparenchymal route,lateral ventricle,carotid artery and tail vein,respectively.The normal rats were used as controls.131 I- FAU was prepared to be the tracer for biodistribution study and the ％ ID/g was calculated based on measurement of the tissue radioactivity counts.The expression of TK gene was evaluated by quantitative real-time PCR (QR-PCR) and Western blot analysis.Data were analyzed with independent-samples t-test,one-way analysis of variance (ANOVA) test,and Pearson linear correlation test.Results The ％ ID/g of infarcted brain tissue in the intraparenchymal group was 0.124 ± 0.013,which was significantly higher than that in lateral ventricle group (0.052 ±0.004),carotid artery group (0.061 ±0.002),tail vein group (0.059 ±0.005) and control group (0.005 ±0.001) (t =2.913 - 5.652,all P＜0.05),while there were no statistically significant differences among the other route transplanted groups ( t =0.694 - 1.448,all P ＞ 0.05 ).The differences of ％ ID/g between the infarcted and contralateral sides of brain tissue in all transplanted groups were statistically significant (t =9.004 - 15.734,all P ＜ 0.05 ),while there was no statistically significant difference of this parameter between both sides of brain tissue in control group (t =1.511,P =0.182).The expression of TK gene in intraparenchymal group was significantly higher than other groups (t =7.482 -12.371,all P ＜0.05).The expression levels ofTK gene on QR-PCR showed a positive correlation with ％ID/g of the brain tissue ( r =0.971,P ＜ 0.001 ).Similarly,the ratio of TK/β-actin by the Western blot analysis correlated with the ％ ID/g ( r =0.899,P =0.002 ).Conclusion Intraparenchymal route may be the way of choice for cell transplantation therapy of cerebral infarction.If suitable radionuclide tracer is available,PET or SPECT may be potentially used for noninvasive monitoring of stem cell transplantation in cerebral infarction in vivo.

Abstract:Alcoholic liver disease (ALD) is one of the most common liver diseases in the world. Long-term alcoholism causes a series of pathological changes in the liver, which eventually leads to the occurrence of liver diseases with an increasing incidence. At present, significant progress has been made in the pathogenesis and pathological development of alcoholic liver disease, but the relevant mechanism of ALD has not been thoroughly studied. It is necessary to improve the existing animal model or establish a new, more comprehensive animal ALD model to simulate human ALD. Experimental animal models of ALD, especially rodents, are often used to simulate human ALD, and the ideal rodent ALD model can effectively simulate all aspects of alcohol in human liver. But so far, the commonly used animal models all have certain defects, and there is no complete animal model that can simulate human ALD. This paper reviewed the pathogenesis of ALD, related methods and influencing factors of ALD model, and provided a theoretical basis for relevant researchers to establish the ALD rodent model. 

OBJECTIVETo evaluate incidence of postoperative delirium after hip surgery in elderly patients by meta-analysis.

METHODSFrom January 1, 2014 to December 31, 2013, clinical literatures about postoperative delirium after hip surgery in elderly patients,were searched from the Pubmed. Literature extract table were formed according to inclusion and exclusion criteria. Stata-12.0 was applied for Meta-analysis. P was used to test heterogeneity of study, random-effect model was performed when I2 > 50%. Subgroup analysis was used according to stage of age, assessment scale of delirium and statistical area of literature. Begg test was used to test publication bias.

RESULTSTwenty-one literatures were included. Incidence of postoperative delirium after hip surgery in elderly patients by weighted and combination was 17% [95% CI (16%, 18%)]. Incidence of postoperative delirium after optional hip surgery was decreased more than emergency operation in included 5 literatures [OR = 0.32, 95% CI (0.22, 0.45)]. Incidence of postoperative delirium in patients less than 80 years old was 21% [95% CI (19%, 23%)], while 21% [95% CI (19%, 24%)] in patients more than 80 years old. Incidence of postoperative delirium in CAM evaluation scale was 23% [95% CI (21%, 26%)], while 19% [95% CI (17%, 21%)] in other evaluation scales. Incidence of postoperative delirium in Asian area was 17% [95% CI (15%, 20%)], while 23% [95% CI (21%, 25%)] in European and American area. There was no publication bias tested by Begg test (P < 0.05).

CONCLUSIONIncidence of postoperative delirium after hip surgery in elderly patients increases higher, especially in emergency operation. A standardizing research method is benefit for evaluate incidence of postoperative delirium after hip surgery in elderly patients, decreasing heterogeneity and publication bias.

Objective To study the immediate effect of applying a portable functional electrical stimulation device (PUEFESD) to the upper extremities of stroke patients.Methods Twenty stroke survivors were selected.Pairs of electrodes of the PUEFESD were applied on the dorsal and palm sides of the affected forearm and thenar to stimulate the extensors and flexors as well as the thenar muscles sequentially according to a programmed protocol.Functional evaluation was conducted before and immediately after the stimulation.All participants were assessed with regard to their motor function and performance in the activities of daily living using an upper extremity function test (UEFT),the upper extremity motor function portion of the Fugal-Meyer assessment (FMA),and rating with the modified Barthel index (MBI).A visual analogue scale (VAS) was used to evaluate pain in the affected upper extremity.Results The patients' average FMA score was 19.4 ± 7.1 before the stimulation and 30.4 ± 9.6 after.The corresponding UEFT scores were 3.6 ± 3.7 and 26.9 ± 5.9,and the average MBI scores were 53.8 ± 26.2 and 65.8 ± 17.7.All of these increases were statistically significant.The average VAS score,however,did not change significantly.Conclusions Functional electric stimulation can quickly improve upper extremity function and the ADL ability of stroke patients,but pain is not relieved significantly.

BACKGROUND: External preparations treatment of fractures in traditional Chinese medidne are mostly ordinary hard-paste, cream, ointment, which lack of modernized traditional Chinese medicine transdermal delivery systems, and the treatment has poor drug absorption and simple process. The treating procedure needs to be used repeatedly, which would affect fracture external fixation and lead to unsatisfactory therapeutic effect. In this Paler, the extemal treatment of traditional Chinese medidna was combined with advanced micro-nano-technology to develop a new medical complex functional materials-micron traditional Chinese medicine functional lining material, which is an organic combination of diaplasis, fixation and local drug remedy, which provides a better treatment for fractures. OBJECTIVE: To explore the effect of micron tradifional Chinese medicine functional lining material on the healing of fracture in rabbits, METHODS: After model preparation, rabbits were randomly divided into 4 groups: rabbits in the micron group were treated with micron traditional Chinese medicine functional lining material plus plaster external fixation; those in the traditional Chinese medidna control group were treated with ordinary Chinese medicine functional material plus plaster extemal fixation; those in the lining material control group were treated with ordinary lining material added plaster extemal fixation; those in the natural healing control group had no special treatments. The effect of fracture healing was evaluated by X-ray at 2, 4 and 6 weeks after modeling. The serum concentration of alkaline phosphatase, calcium and phosphorus was detected respectivaly before modeling and at 2, 4 and 6 weeks after modeling. RESULTS AND CONCLISION: ①X-rap examination:After 6 weeks the external was almost copletly absorbed and medullary cavity was completely recanalizad in the micron group, while fracture line disappeared and the external callus began to be absorbed and medullary cavity was not recanalized in the traditional Chinese medidne control group. Additionally, there were case of non-union stump hardening in natural healing group. ②Serum biochemistry:The activity of alkaline phosphatase reached a peak after 2 weeks in micron group, which was 2 weeks ahead of time compared with that in traditional Chinese medicine control group. And the peak concentration of alkaline phosphatase in micron group was higher than other groups. After 4 weeks serum calcium concentration started to fall significantly and phosphorus concentration started to rise significantly in micron group, as was statistically significant compared with other groups. After 6 weeks serum calcium concentration in micron group had fallen to normal level, while that in other groups was higher than normal. And phosphorus concentration in micron group increased significantly, which was statistically significant compared with natural healing group. The results demonstrated that micron feature traditional Chinese medicine lining matedat can enhance the activity of alkaline phosphatase, decrease the serum concentration of calcium and increase the serum concentration of phosphorus and the product of calcium and phosphorus, therefore, promote the healing of fracture, It shows that micron traditional Chinese medicine functional lining matedal plays a stronger effect on promoting the healing of fracture than that of ordinary Chinese medicine functional lining material.
