High resolution melting ( HRM) analysis is a real-time PCR based technique which can detect DNA sequence polymorphism .Immediately after routine PCR with saturated fluorescent dye , melting transition of the amplicon was monitored and fluorescence was collected .According to the different melting curve, single base differences can be distinguished .HRM is a low -cost, single -step, closed -tube, accurate and rapid method , which has aroused general concern .Rapid and sensitive detection of the clinical pathogens is critical to diagnosis of infectious diseases .However , clinical research on application of HRM in infectious disease pathogen identification and drug resistance , especially melting curve analysis based bedside technology integration will provide strong support for the diagnosis and treatment of infectious diseases.

Objective To visualize blood flow changes in verruca vulgaris noninvasively with laser speckle contrast analysis (LSCA), and to evaluate the relationship of size and location of warts with efficacy of laser treatment. Methods Pulsed dye laser(PDL)was used to treat 30 verruca vulgaris lesions in 17 patients. In order to evaluate therapeutic effect of PDL, LSCA was performed to observe blood flow in warts and their surrounding normal skin, and to calculate speckle flow index (SFI)values before laser treatment, and at 10 minutes as well as on 3 weeks after laser treatment. Results Before PDL treatment, SFI values were significantly higher in warts than in their surrounding normal skin (11.600 ± 1.190 vs. 5.280 ± 0.481, t = 8.169, P < 0.01). Compared with those before the treatment, SFI values in warts significantly decreased at 10 minutes(3.112 ± 0.484, t = 4.407, P < 0.01)and on week 3(7.315 ± 1.083, t = 3.294, P < 0.01)after the treatment, and were significantly higher on week 3 than at 10 minutes (t = 4.646, P < 0.01). SFI values in surrounding normal skin significantly increased at 10 minutes after the treatment compared with those before the treatment (20.260 ± 2.063 vs. 5.296 ± 0.708, t = 6.770, P < 0.01), but were significantly lower on week 3 than at 10 minutes (4.941 ± 0.616, t = 6.964, P < 0.01). No significant difference was observed between SFI values in surrounding normal skin on week 3 after the treatment and those before the treatment (t = 0.378, P = 0.707). The efficacy of laser treatment was associated wart size and location. Changes of blood flow(|ΔSFI|)were significantly higher in warts measuring less than 0.5 cm2 in size than in those equal to or more than 0.5 cm2 (t = 2.287, P < 0.05), and significantly differed among warts at different sites (F =15.71, P < 0.01). The greatest changes of blood flow in warts were observed on fingers, followed by the dorsum of feet, toes, palms and soles and periungual areas. Conclusions Blood flow in verruca vulgaris is markedly increased compared with that in normal skin. PDL can clear verruca vulgaris by solidifying and gasifying capillaries. LSCA may be used to evaluate the efficacy of laser on verruca vulgaris more quantitively by monitoring regional blood flow.

Objective To improve the effectiveness of internship nursing students in infectious diseases by implementing peer teaching method. Methods The nursing students were divided into two groups according to the order of student number. The control group was given the teaching method of the general outline.

Results There were significant differences between the two groups in terms of the results of the three tests and the theoretical evaluation, and the results of the test group were better than those of the control group (P<0.05). Conclusion Peer- to- peer learning method can improve the practical effect of surgical nursing students in infectious diseases, and can be popularized in a certain extent.

Objective To explore the pathogenesis, reason, diagnosis and treatment of cerebral salt wasting syndrome (CSWS) in the patients with serious cerebral injury. Methods The clinical data of 26 cases of CSWS after serious cerebral injury were analyzed retrospectively. Results The diagnosis of CSWS was confirmed by clinical symptoms of the patients and the results of laboratory examinations. After the effective treatment, the low plasma sodium level of 21 patients was corrected, and 5 patients died. Conclusion Hyponatremia,hypernatruria, hypovolemia, the increase of urinary amount and the elevation of plasma ANP and BNP level were main characteristics of CSWS.The supplement of water and salt was safe and effective in the treatment of CSWS.

Objective To study the percentage and the distribution of nosocomial infection, and susceptibility of related pathogens to antibiotics in patients with systemic lupus erythematosus (SLE). Methods The clinical data of in patients with SLE in our hospital from June, 1990 to June, 1998 were analyzed. The susceptibility of the pathogens to antimicrobial agents was tested by K-B paper dilution method. Results The percentage of nosocomial infection in these cases was 16.1％ . The major pathogens were staphylococcas aureus, Escherichia coli and Candida. The most highly resistant microbes were E.coli, S.arueus and Pseudomonas aeruginosa. Conclusions The nosocomial infection is one of the most common complication of SLE in the in patients. It is necessary to examine the pathogens regularly and use antibacterial agents according to the susceptibility.

ObjectiveTo find out about changes in expenses and the orientation of the insured to medical services and analyze the causes of expense growth and the result of containment so as to offer suggestions for policy formulation. MethodsA statistical analysis was made of the actual data on the medical insurance of retired and working personnel in Nantong City from 2000 through 2002 using SPSS and Excel. Results①The mode of payment via "plate" management and total quantity and mean value control resulted in fairly good expense containment, especially outpatient expense containment while the growth of hospitalization expenses was on the rise. ②Third-tier hospitals were most popular to people seeking hospitalized services while for outpatient services people were increasingly turning to clinics and designated drugstores where the average expenses per visit were low. Conclusion①The managing party of medical insurance should step up research on expense containment strategies, steer the patients towards rational splitflow, try to contain expenses in a scientific way, and improve the efficiency of fund utilization. ②Medical institutions confronted with opportunities and crises should enhance quality construction and deliver standard and reliable services. ③It is imperative to strengthen regional health planning and raise the efficiency of health resources utilization.

Objective To study the correlation between the dynamic changes of sex hormones and the severity and prognosis of head injury,and to investigate the role of sex hormones in traumatic brain injury.Methods The dynamic changes of sex hormones were quantitatively dynamic measured in 100 patients with head injuries,while the relationships between glasgow coma score(GCS),glasgow outcome score(GOS) and the concentration of sex hormones were also studied.Results The estradioi,progesterone and testosterone levels in serum increased within 12 hours after trauma in all groups.Estradiol increased markedly continuously within 1,3 days in GCS≤12 group,testosterone levels in serum decreased within 3 days after trauma in GCS=3～8 group,with a significant differnce compared with others groups.The concentration of sex hormones correlated positively with GOS.Conclusions The measurement of sex hormones may be useful to judge the severity and prognosis of head injury in earlystage.The increases of estradiol in the early stage after traumatic brain injury may exert powerful protective effects on brain tissues.Decreases of sex hormones are important factors leading to death of patients of traumatic brain injury.

BACKGROUND: There is still recrudescent risk in the convalescence stage of the acute myocardial infarction and the living condition is relatively poor. The study proved that it has relation to that the patients haven't mastered the scientific conformable life style for the myocardial infarction recovery.OBJECTIVE: Take the rehabilitation education to help the patients set up conformable life style so as to improve the quality of life.DESIGN: The patients in the convalescence stage of the acute myocardial infarction were chosen for the control study.SETTING: Nursing Institute of Beijing Medical University and two university hospitals.PARTICIPANTS: The cases were taken from the Cardiology Departm ents of the Second and Third Affiliated Hospital of Beijing Medical University from April 1999 to November 1999. Inclusive standard: the first onset of the acute myocardial infarction and voluntary for this study. Exclusive standard: not the first onset of the acute myocardial infarction. The control group contained 35 patients hospitalized from April 1999 to June 1999 conforming to the including standard. The experimental group contained 40 patients hospitalized from August 1999 to November 1999 conforming to the including standard. After eliminating the special unmatched cases and missed follow-up cases in the experimental group, the final 30 cases were respectively involved in the both groups. There were 23 male cases and 7 female cases in the control group with the mean age of(60 ± 14), and 22 male cases and 8 female cases in the experimental group with the mean age of(62 ± 10) . There was no significant difference in the age and sex in these two groups.METHODS: The Neuman health care system pattern was taken as the theoretical frame for the rehabilitation education of the patients in the convalescent stage of the acute myocardial infarction. That is the conver genceteaching and personal illustration accompanied the rehabilitation education hand books were adopted for the rehabilitation education in the experimental group before their leaving. Then the telephone education was taken for further direction and consultation during the first three months after being discharged. The evaluation information was obtained through the follow-up after the first three months.MAIN OUTCOME MEASURES: The quality of life and dimensions in the two groups.RESULTS: Compared with the control group, the scores of the quality of life, the dimensions of the body, the psychology, the duty role and the health consciousness in the experimental group were all significantly higher(t= 11.03,3.26,3.62,2.05,15.48, P < 0. 05), while there was no significant difference in the social degree( P > 0.05) .CONCLUSION: The rehabilitation education can significantly improve the quality of life of the patients in the convalescence stage of the acute myocardial infarction.
