Objective To explore the application effect of single port laparoscopic techniques in urology grassroots.Methods 60 patients with upper ureteral stones were randomly divided into observation group(using single port laparoscopic technique lithotripsy) and control group (30 cases with open surgery).The surgery time,blood loss,hospital stay,postoperative complications were compared between the two groups and the patients were followed up for three months,the clearance rate of stones and patients' satisfaction were observed.Results The operative time between the two groups had no significant difference(t=1.559,P>0.05).The blood loss of the observation group was significantly less than that of the control group[(128.3±10.32)mL vs.(76.4±9.65)mL],the difference was statistically significant(t=20.003,P<0.01),and the hospitalization time was shorter than that of the control group[(5.86±1.47)d vs.(7.95±1.53)d],the difference was statistically significant(t=5.395,P<0.01).The incidence rate of postoperative complications of the observation group was lower than that of the control group(6.7% vs.30.0%),the difference was statistically significant(x2=5.454,P<0.05).Followed up for 3 months,the ESWL rate(73.3% vs.96.7%) and satisfaction rate (100.0% vs.80.0%) in the observation group and the control group had statistically significant differences (x2=4.705,4.629,all P<0.05).Conclusion The single port laparoscopic technique lithotripsy in the treatment of upper ureteral stones has precise effect,less invasion,high ESWL rate,low complication rate and other advantages,and it is worthy of wide promotion.

Objective To explore the effects of recombined human growth hormon-enhanced early enteral nutrition on healing of the patients after operation for sereve abdominal trauma.Methods 60 patients with severe abdominal trauma were randomly divided into PN(n=20),EN(n=20) and EN+ rhGH(n=20) groups.Nutrient status and immune function of 3 groups were detected on the postoperative day 1,7 and 10.Results EN+ rhGH group showed more effective process than EN and PN groups in improving postoperative nutrient status,immune function and nitrogen balance,whose indexs except CD8 changed significantly on the postoperative day 7 and 10 than that in PN group(P

AIM: To investigate the correlation between the left ventricular filling type and geometry modality and functional change of the left ventricle in patients with hypertension. METHODS: Systolic function indexes (FS and EF) and diastolic function indexes (E, A, EAT, EDT, E/A,IVRT) in 120 patients with hypertension were measured by two dimensional ultrasonography (2-DUS) and M-mode and Doppler ultrasound. RESULTS: A rate of 83.5% in patients with hypertension appeared assured plump and configuration changes of left ventricle, and a rate of 84% in patients with hypertension appeared abnormal left ventricular filling function. The morphologic indexes were significantly different clearly in different left ventricular filling types, and the filling indexes were also significantly different in diferent left ventricular shapes. CONCLUSION: IVRT is a more important index than other factors to decide the left ventricular filling function. LVMI plays more important role than other factors in the left ventricular filling function.

Objective To find out the iodine nutritional status of school-age children in Yichang city,and to provide a scientific basis for prevention and control of iodine deficiency disorders.Methods In 2009,children aged 8 to 10 in each county(city,region) in Yichang city Hubei province were selected as study subjects.In each county (town,district),a township(town,street) was selected according to their orientation of east,west,south,north and center in the county.A village primary school was selected from each township(town,street).Twenty children aged 8 to 10 from each school were selected.Real-lime urine samples were collected to test iodine level.Results A total of 1300 urine samples of school children were collected and tested.The median urinary iodine was 277.4 μg/L.Therein,there were 11 children whose urinary iodine level was less than 20 μg/L,accounting for 0.8％ ; there were 28 children whose urinary iodine level was between 20 μg/L to 50 μg/L,accounting for 2.2％ ;there were 84 children whose urinary iodine level was between 50 μg/L to 100 μg/L,accounting for 6.5％; there were 606 children whose urinary iodine level was between 100 μg/L to 300 μg/L,accounting for 46.6％; there were 571 children whose urinary iodine level was more than 300 μg/L,accounting for 43.9％.There were 648 males,their median urinary iodine was 263.1 μg/L.There were 652 females,their nedian urinary iodinc was 277.5 μg/L.A total of 388 eight-year-old children's median urinary iodine was 277.5 μg/L.A total of 458 nine-year-old children whose median urinary iodine was 259.4 μg/L.A total of 454 ten-year-old children whose median urinary iodine was 295.8 μg/L.Conclusions The iodine nutrition of school-age children in Yichang city is in good condition,and complies with the national standard of eliminating iodine deficiency disorders.But the urine iodine content is higher than the appropriate level,so there is a need to strengthen the prevention work.

Objective: To investigate the characteristics of brain laterality in patients with childhood onset schizophrenia. Methods: The study employed a dichotic Chinese word listening test(DL) as a chief measure and WISC-R as an assistant measure to examine 16 patients and 20 normal children as controls. Results: DL indicated that the patients differed from the controls in ear advantages and their performances were significantly poorer than the controls in left ear. The performances of the patients on WISC-R showed that their PIQ was significantly lower than VIQ. Conclusion:The patients with childhood onset schizophrenia differed from the controls in brain laterality. They might be involved with right hemisphere impairment.

Objective:To analyze the teaching status of medical imaging equipment and the requirement of medical imaging equipment for graduates majored in medical imaging technique, and then make great progress in the teaching reform of medical imaging equipment.Methods:Discussed with students, conduct investigations and surveys on kinds of hospital in Beijing, and analyzed the survey data.Results: With the analysis of survey, the teaching reform scheme was proposed in the course.Conclusion: To establish the foundation for the teaching reform of medical imaging equipment.

The development of the nerves of the small intestine was studied in 26 human fetuses with the gestational age of 11 to 40 weeks.The findings are as follows:(1)The distance between the Auerbach's ganglia and the muscular layer is small in the early fetal period and it increases progressively as the fetus grows.(2)The density of neuropils increases gradually.(3)The number of large gradual vacuoles (LGV) is small in the 3rd month of gestation,and it increases gradually and is quite numerous in the 6th month.(4)The morphology of the synapses is not so typical as that of an adult.(5)The peak values of the stereological morphological parameters of the organelles in the neurons appear between the 4th-6th month and maintain at a relatively high level until the baby is bron.

Objective: To evaluate the preventive effect of ephedrine on hypotension under spinal anesthesia in patients with different age. Methods: Sixty patients scheduled for spinal anesthesia were randomly allocated to four groups with 15 each. Group Ⅰ and Ⅱ were adult patients aged from 25 to 55 years old and group Ⅲ and Ⅳ were geratic aged patients of 6575 years old. Every patient received a fluid loading of 7ml/kg before spinal anesthesia. The ephedrine was administrated to group Ⅱ and IV patients in a dose of 10mg i v and 30 mg i m and same amount of normal saline was administrated to group Ⅰ and Ⅲ as soon as spinal anesthesia was performed. Results:Thirty patients in the placebo groups developed a maximal decrease in MAP exceeding 20%. Ten of these (2 in group Ⅰ and 8 in group Ⅲ ) developed a decrease in MAP exceeding 35% and required treatment. In aged groups, all patients in group Ⅲ had a decrease in MAP exceeding 20 %, 53 % of whom, the decrease exceeded 35 %. Conclusion:Prophylactic use of ephedrine is effective in the prevention of hypotension during spinal anesthesia, especially in aged patients.
