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.

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 find out the situation of the use of antimicrobials in perioperative patients and to evaluate the rationality of use.METHODS: To make a survey of the use of antimicrobials in 230 surgical patients during the period Dec. 2002 - Apr. 2004, and to evaluate the kinds, frequency, cost - effectiveness ratios, combined administration, course, effectiveness and drug adverse react ions. RESULTS: 100 percent patients had received antimicrobials involving 32 kinds of drug and 8 595 case - time.The cost of consumption of antimicrobials per case was 1 183.5 yuans.The average therapeutic course was 21.89 days.The operation incisions healed by first intention in 230 cases.The cost ratios of total drugs and antimicrobials was 1 : 0.41 .CONCLUSION:The supervision of using antimicrobials in perioperative period must be reinforced.

Objective:To explore the future development of pharmacists. Methods:The combination of on-site and mailed ques-tionnaire was adopted to investigate the present work situation of pharmacists in hospitals at different levels in 15 provinces and munici-palities of east China. Based on the statistical analysis of data, some problems in the present work of pharmacists were investigated. Results:The data showed that there was a wide gap of human resource among the hospitals at different levels, and the working condi-tion improvement for pharmacists should be performed. Continuing education and legislation were not standardized and unified yet, and the clinical pharmacy and the rational drug use needed further development. Conclusion:The relevant laws and regulations should be established and improved to guarantee the lawful right and interests of pharmacists. The pharmacist training system should be improved to raise the professional quality of pharmacists and promote the development of hospital pharmacy.

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.

Objective To evaluate the CT findings of the parotid basal cell adenoma and it's diagnostic value.Methods The CT appearances of 10 patients with parotid basal cell adenoma confirmed by histopathology were reviewed retrospectively.The plain and the contrast-enhanced CT scan were performed in all cases.Results The well-defined mass in varied size with marked enhancement in contrast-enhanced CT imagines,in which the CT value increased to 200Hu maximally(average,84Hu),were the pathognomonic CT characteristics of the parotid basal cell adenoma.Conclusion The qualitative diagnosis of the parotid basal cell adenoma could be made based on the CT findings combined with some valuable clinical information before operation.

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.

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.

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.
