Objective To explore the application value of single intensifying screen cassette in examination of Kashin-Beck disease through X-ray photographing.Methods Single intensifying screen cassette and traditional changing bag with exposure conditions were used to check right wrists of 110 children in Kashin-Beck disease areas.The FJ personal dosimeter was used to measure exposure dose.Photo graphing quality and diagnosis effect were assessed.Results The radiation dose of children in single intensifying screen cassette group was (207 ± 39)μsv/h,while in the traditional changing bag group was (1425 ± 63)μsv/h.The difference between the two groups was statistically significant(t =140.16,P < 0.05).The high-quality photograph rate of the two methods was 94.55% (104/110) and 92.73% (102/110),respectively,and the difference was not statistically significant(P > 0.05).The good photo rate in the single intensifying screen cassette was 96.36% (94/110),which was significantly higher than that of the traditional changing bag group[44.55% (49/110),x2 =70.92,P < 0.01].Conclusions X-ray radiation dose in single intensifying screen cassette group is smaller than that of the traditional changing bag group,and the image quality of the radiograph of the new method is also superior.It has a good practical value in the X-ray examination of Kashin-Beck disease.

Three osmotolerant yeasts were isolated from three batches of "swollen can" soy sauce produced by a Guangdong condiment plant. These strains grew faster in the media containing 50%~60% glucose or 15% NaCl than in common yeast media. The three yeasts were identified as Pichia etchellsii by using morphological characteristics, physiological and biochemical tests.

OBJECTIVETo discuss the choice of surgical methods and the safety and efficacy of off-pump coronary artery bypass grafting (OPCAB) in elderly patients.
METHODSFrom Sept. 1997 to Feb. 2003, 63 cases over the age of seventy (including seventy) undertook OPCAB in our department. We compared the clinical data of those patients with that of 94 cases undertook conventional coronary artery bypass grafting (CABG) at the same age group and that of 58 cases younger than seventy received OPCAB.
RESULTSThe clinical outcomes of OPCAB is better than that of CABG in elderly patients concerning inotropic drug, postoperative transfusion, re-operation, intubation time, complications incidence and in-hospital mortality. Furthermore, there is no significant difference of complication incidence and in-hospital mortality between the elderly OPCAB group and the younger OPCAB group.
CONCLUSIONSOPCAB is a safe and efficacious method of myocardial revascularization in the elderly.

The chemical shift of fluoxetine hydrochloride appears at delta 14.15 in 19F NMR analysis. The delta moved upfield slightly from 14.158 to 14.145 when the concentration of solution became diluted from 2.00 to 0.05 mmol x L(-1). Spiking test was suggested to confirm the existence of the compound for qualitative analysis. 19F NMR detection sensitivity test illustrated that a concentration of 17 mg in 1 L water could be detected while the sample was scanned 500 times with optimum parameters. In quantitative analysis, standard curve of concentration versus fluorine signal intensity was proposed to determine the amount of fluoxetine. Long capillary tube containing trifluoroacetic acid was used as internal standard for the integration measurements and straight line was obtained with good fitting. Direct additions of trifluoroethanol to fluoxetine solutions gave a poorer standard curve.

Objective To evaluate the role of late course accelerated fractions.ted irradiation(LCAF) combined with concurrent chemotherapy in the management of esophageal carcinoma.Methods From March 1998 to July 2000,111 eligible patients were randomized into LCAF alone group(LCAF,57 patients)or LCAF plus concurrent chemotherapy group(LACF-CT,54 patients).The radiotherapy regimen was identical in the two groups,consisting of conventional fractionation in the first 2/3 course and accelerated fractionation in the second 1/ 3 course to a total dose of 68.4 Gy/41 Fx/44 d.Chemotherapy regimen consisted of four eycles of cisplatin 25 mg/ (m~2?d)plus fluorouracil 600 mg/(m~2?d)on day 1 to 3 every 4 weeks and was delivered on the first day of radiotherapy.Results The median follow-up time was 67.1 months(range 47.6-76.4 months).The 1-,3-,5- year survival rate was 67%,44% ,40% and 77%,39% 28% in LACF-CF and LEAF group,respectively(P =0.310).Grade 3+4 acute side-effact was 42% and 25% in LCAF-CT and LCAF group,respectively(P<0. 05),with 3 treatment-related deaths in the LCAF-CT group.Conclusions Late course accelerated fractionated irradiation combined with concurrent chemotherapy has a trend towards improving the survival,at the cost of increasing acute side-effect.Its role needs further confirmation by larger sample studied in randomization.

Objective To investigate the effect of oral alpha-lipoic acid (ALA) supplement on brachial-ankle pulse wave velocity (baPWV),supine systolic blood pressure (SBP) and diastolic blood pressure (DBP) in overweight/obese individuals.An 8-week double-blind,randomized,placebo-controlled and cross-over trial with a 4-week washout between cross-over periods.Methods Sixty-three males and 40 females aged 22-57 years old who met the inclusion criteria as (1) Han ethnicity;(2) 20-60 years old;(3) BMI≥25 kg/m2 and having at least one of the following risk factors:borderline hypertension (130 mm Hg≤SBP<140 mm Hg and/or 85 mm Hg≤supine DBP<90 mm Hg),dyslipidemia(fasting total cholesterol≥5.2 mmol/L or HDL-C<1.04 mmol/L),or impaired fasting glucose (6.1 mmol/L≤fasting glucose<7.0 mmol/L);(4)Not on any antioxidant gender.Group 1 received 8 weeks ALA (1200 mg/day) followed by 4-week washout period and followed by another 8 weeks placebo;while Group 2 received 8 weeks placebo (1200 mg/day)followed by 4-week washout period,and followed by ALA treatment for 8 weeks.BaPWV and supine blood pressure were measured at the beginning of 1st phase and 2nd phase and at the endpoint of the whole trial.Mixed effect linear regression model was performed to compare the change of baPWV and supine blood pressure between ALA group and placebo group.Results BaPWV decreased -33.03 cm/s ± 130.70 cm/s for ALA group and increased 5.66 cm/s ± 139.89 cm/s for placebo group,supine systolic blood pressure decreased -4.09 mm Hg±9.18 mm Hg for ALA group and -2.32 mm Hg±8.16 mm Hg for placebo group.Supine diastolic blood pressure decreased -1.29 mm Hg ± 6.55 mm Hg for ALA group and -0.48 mm Hg±6.63 mm Hg for placebo group.These three mix-effect models did not show significant effect of ALA treatment after adjustment on baseline values,sex,age,treatment sequence or period.Conclusion The current trial did not provide evidence that oral intake of ALA for 8 weeks had significant effects on lowering baPWV,supine systolic blood pressure or supine diastolic blood pressure.

OBJECTIVETo study the effects of Compound Salvia miltiorrhiza Injection (CSI) on aquaporin 3 (AQP3) expression in human amniotic epithelial cells (hAECs), and to explore its mechanisms for treating oligohydramnios.
METHODSThe hAECs selected from 8 human term pregnancies with oligohydramnios and no other complications (as the test group)and 8 human term pregnancies with normal amniotic fluid volume (as the control group) were primarily cultured. The mRNA and protein expressions of AQP3 in hAECs were detected using reverse transcription-polymerase chain reaction and Western blot with various concentrations of CSI (0.000, 0.001, 0.010, 0.020, 0.060, and 0.100 mg/mL, respectively) at different time points (0, 6, 12,24, and 48 h, respectively).
RESULTS(1) Compared with the control group, the AQP3 expression was down-regulated in the test group (P < 0.05). (2) The AQP3 expression in the two groups reached the peak when the concentration of CSI was 0.010 mg/mL, showing statistical difference when compared with other concentrations (P < 0.05). (3) The AQP3 expression reached the peak when 0.010 mg/mL CSI acted for 12 h, showing statistical difference when compared with other concentrations (P < 0.05). (4) The AQP3 expression was up-regulated in the two groups when 0.010 mg/mL CSI acted for 12 h. But the up-regulated AQP3 expression was more obvious in the test group than in the control group (P < 0.05).
CONCLUSIONSCSI could regulate the AQP3 expression in hAECs. CSI showed more obvious effects on the AQP3 expression in hAECs of oligohydramnios human term pregnancies.
