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 sedation efficacy of propofol combined with midazolam and /or fentanyl in fibreoptic choledochoscope. Methods Ninty outpatients were randomly divided into three groups. Group PF (n=31)was given fentanyl 0. 05 m.g plus propofol 1 mg/kg intravenously, group PM (n=29) midazolam 2 mg plus propofol 1 mg/kg, and group PMF(n=30) fentanyl 0. 05 mg, midazolam 2 mg and propofol 1 mg/kg. Propofol 20 mg was used when needed. HR,MAP,SpO_2,sedation scores and amnesia were recorded. Results All patients were awakened in 20 minutes after procedures. The recovery time was shorter in group PF than that in the other two groups. There were 21(67. 70%) patients in group PF, who were aware of surgery. Fifteen(48. 4%) patients were satisfied in group PF. Conclusion Propofol combined with midazolam and /or fentanyl in fibreoptic choledochoscope has better sedation without any obvious side effects.

To meet the comprehensive medical needs of experimental teaching and reform, building a targeted, full-featured intelligent experimental teaching management system. The practical application of laboratory and laboratory equipment to improve operating efficiency and management level, to improve the quality of the teaching experiment, has good prospects and promotion of value.

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.

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.

Objective To observe the effect of triplex surgical treatment, including rectal mucosa ligation,Xiaozhiling injection,encircing fighting surgery of the anus ring,on complete rectum prolapse. Methods From February 2007 to February 2010,fifteen cases with complete rectum prolapse were enrolled into this study and accepted triplex surgical treatment All patients were followed up for 1-4 years. Results The curative rate of the triplex surgical treatment was 100% with no serious complications. Conclusion Triplex surgical treatment was a simple, effective and reliable method in treating complete rectum prolapse, with less pain,fewer complications and quicker recovery.

Objective To understand and to assess the current situation of iodine deficiency disorders in Qaidam Basin,and to provide the information for measures and strategies of prevention and cure of this disease.Methods Within the boarder of Qaidam,five counties(cities)were selected for the investigation,which were Delingha,Golmud,Dulah,Wulan,and Tianjun.Two townships(towns)have been selected in each county(city),51 students aged 8 to 10 in one of the primary schools in each township(town)underwent thyroid palpation examination,their urine samples were collected to test urine iodine using arsenic-Ce catalysis spectrophotometric method.Thirty students of fifth-grade class in the selected schools underwent the questionnaire of prevention knowledge of iodine deficiency disease,while 10 housewives in each village near by the school were asked for the same questions,and the edible salt in their home was quantified of iodine by using direct titration method.Results Among the children aged 8 to 10,the average prevalence rate of thyroid enlargement Was 5.9%(30/510),higher than that stipulated by the national standard.The median of urinary iodine of urinary iodine level for children aged 8 to 10 was 83.4μg/L,the ration of urinary iodine＜20μg/L Was more than 10 percent;qualified iodized salt consumption rate of residents was 59.0%(118/200);the average scores and the checkout rate of fifth-grade students and the housewives who had underwent the questionnaire survey were 31.5,12.0%(36/300)and 35.9,18.5%(37/200)respectively.Conclusions The prevention and cure of iodine deficiency disorders in selected area do not work well,iodized salt is not popular,therefore health education needs to be strengthened.
