The test procedure and content of valves pressure test of AK95 hemodialysis machine are mainly introduced.The valves pressure test are the key of the self test procedure in hemsdialysis machine.It is necessary to find the accurate process where problems occur.[Chinese Medical Equipment Journal,2008,29(2):94]

The BM self-test of GAMBRO AK95 hemodialysis machine is introduced, including venous pressure test, arterial pressure test, priming detector test, blood pump test, venous clamp test, arterial clamp test, air detector test, high venous pressure test, etc. The detail introduction of high venous pressure test is of great benefit to solve some faults of hemodialysis machine.

OBJECTIVE:To observe clinical efficacy and safety of Autoserum eye drops in the treatment of filamentary kerati-tis after excimer laser corneal refractive surgery. METHODS:46 patients (90 eyes) with filamentary keratitis after excimer laser corneal refractive surgery were selected and randomly divided into control group and observation group with 23 cases(45 eyes)in each group. The control group was given clearing mesh+wearing soft contact lens+bFGF eye drops;the observation group was giv-en clearing mesh+ wearing soft contact lens + Autoserum eye drops. The clinical efficacy,cure time,recurrence rate and ADR were compared between 2 groups. RESULTS:The total effective rate of observation group was 93.3%,which was higher than that (82.2%)of the control group,with statistical significance(P<0.05);the cure time of observation group was(2.7±1.1)d,which was shortened significantly compared with control group [(3.5±1.2)d],with statistical significance(P<0.05). The recurrence rate of filamentous keratitis was 4.4% in observation group and 15.6% in control group;the observation group was significantly lower than the control group,with statistical significance(P<0.05). During the treatment,there were 1 case(1 eyes)of corneal epitheli-al edema in observation group and 2 cases (2 eyes) of corneal epithelial edema in control group,there was no statistical signifi-cance(P>0.05). CONCLUSIONS:In the treatment of filamentous keratitis after excimer laser corneal refractive surgery,therapy of clearing mesh+wearing soft contact lens+Autoserum eye drops have high total effective rate,low recurrence rate and short cure period with less ADR.

Objective To study the ultrasonographic changes and blood flow characteristic ofthromboangiitis obliterans (TAO) by two-dimensional ultrasound and color Doppler imaging MethodForty-seven vessels of 40 patients with clinically suspected TAO vascular detected with two-dimensionalultrasound and color Doppler,and comparison with CT imagmg.Results Color Doppler imaging couldvisualize the arterial wall and blood flow echo filling case,and the spectrum showed the hemodynamicchanges.Conclusions Color Doppler is the first choice for the secondary check to the noninvasivethromboangiitis obliterans,close to the result by an angiography that is usually regarded as a sensitive,accurate and convenient diagnostic method.

Applying formative assessment in teaching medical biomathematics course can comprehensively evaluate students and stimulate and develop students' interests in learning.The assessment contents included in class performance,study strategies,self-study abilities and internet interaction.Combined application of formative assessment and final summative examination evaluation in the process can promote the self-study,comprehensive evaluation and achieve good results.

Basic medical theory integrating with clinical practice is the motivation of medical development.In our country,basic medical theory research levels has been low because of mismatch between clinic practice and basic research in lots of affiliated hospitals of medical colleges.In this paper,according to analysize the basic medical research status of several affiliated hospitals of Shantou University Medical College,we think that it is key for enhancing basic research levels to strengthen building clinical research platform,standardize management of scientific research and guide medical staffs carrying out basic theory research from clinic practice.

With the development of computing and storage techniques,there are a lot of medical records and clinical data stored.It raises the issue of how to mine knowledge from these records and to promote the development of traditional Chinese medicine (TCM).Several challenging research subjects of Chinese clinical medicine data mining and analysis have been introduced in the framework of disease-symptom-syndrome-formulaeffect,and the corresponding developments have also been reported.The significant meaning of the data mining and analysis to Chinese medicine is discussed.Then,the detailed works and recent achievements of seven subjects are given including:① Analysis of symptoms to obtain the optimal symptom subset for one disease or syndrome.② Symptom-syndrome or disease to obtain models for syndrome differentiation.③ Analysis of syndrome.④Analysis of Core formula as well as drug addition and subtraction.⑤ Formula-symptom-effect.⑥ Computerized symptoms.⑦ TCM knowledge engineering.

BACKGROUND: Periprosthetic infection after total hip replacement usually results in surgery failure and needs a second operation.OBJECTIVE: To explore the pathogenesis, diagnosis and treatment of periprosthetic infection after total hip replacement by-reviewing and summarizing articles published in recent years.METHODS: A computed-based online search of Pubmed database was performed by using the key words of total hip arthroplasty, infection for manuscripts published from January 1990 to December 2010 and of those in SpringerLink database between January 1,1970 and December 31, 2010. A total of 2 109 manuscripts were retrieved. Moreover, related book or manuscripts that published by high-impact journals were included. Totally, 29 manuscripts were included. RESULTS AND CONCLUSION: The formation of biofilms on the surface of prosthesis is the main cause for hardly eradicated. Resistant bacteria and polymicrobial infection seems to be an increasing tendency. A correct diagnosis as soon as possible is very important to prognosis. However, without a gold-standard way, each mean has advantages and shortages, and comprehensive considerations are necessary. lnterleukin-6 seems a good choice for its inexpensive, non-invasive and a high sensitivity and specificity, which has aroused increasing attention. The antibiotics only, debridement with retention, one-stage replacement, two-stage replacement, joint arthrodesis, even amputation, are used to treat infection after total hip replacement. Prophylactic antibiotics are important to prevent infection. Antibiotic-loaded acrylic cement seems to be reliable and accept for more and more patients. However, each option must be selected according to the presence of infection individually.

Objective To investigate the aim antigen coursing the hyperacute rejection of xenotransplantation. Methods Documents about hyperacute rejection in xenotransplantation were reviewed and summarized in detail. Results Pig is thought to be one of the ideal donors of xenotransplantation, but the major obstacle is hyperacute rejection mediated by complement that is activated though human serum. ?-Gal is recognized as the major antigen and its expression is controlled by ?-1,3 galactosyltransferase. Immunoabsorption of pre-exsisted antibody, enzymatic digestion of ?-Gal, knockout ?-GT gene and transgenic technology have been used to solve this problem. Even so, there remain other antigens which can combine with natural antibodies in human serum, such as, 40?10 3 molecule in erythrocyte, 210?10 3, 10 5?10 3 and 50?10 3 antigen in pig embryo brain cell, etc. Conclusion ?-Gal is the major antigen which course the hyperacute rejection. Besides ?-Gal, many nonalpha-gal need further investigation.

Objective: To get the information about freshmen's mental health and it relationship with sex, city and countryside difference, and to provide the reference for effective mental health education and consultation. Methods: The situation of 1351 freshmen's mental health was surveyed by using UPI. Results: ①11.91% of the freshmen had serious mental derangement, 26.15% of them had a little psychological problem. ②The distinct difference existed not only between male and female, but also between city and countryside. The mental health of male students surpassed the female students, the city students surpassed the countryside students. Conclusion: The situation of medical freshmen's mental health should not be neglected, and its influence factors are various. Mental health education and consultation should be pointed to the students.
