Objective To study paraquat adsorbability of different field soils in Guangxi province of China. Methods HPLC method was adopted to measure the peak area of paraquat in three different media of four types of soils. Chromatographic column was Kromasil C18 column (4. 6 mm×200 mm, 5 μm); mobile phase was acetonitrile-water (including 0. 03 mol·L-1 sodium heptanesulfonate and 0. 24 mol·L-1 phosphoric acid) at a ratio of 397 (pH adjusted to 2. 0 by triethylamine). Detection wave length was 258 nm; column temperature was 25 ℃; the injection volume was 20 μL; flow rate was 0. 8 mL·min-1 . The peak areas of paraquat before and after being adsorbed were compared to calculate the adsorption rate of paraquat in different soils. Results All tested soil samples possessed the adsorption rate of paraquat over 99. 0%. Conclusion Four common field soils in Guangxi province can be used as temporary effective absorbents for the first-aid of paraquat poisoning.

Objective To explore influence of perioperative protection from hypothermia on surgical site infection (SSI) in patients undergoing gastroenteritic operation. Methods A retrospective study was carried out in 1536 patients undergoing gastroenteritic operation in general surgery department of our hos-pital.Patients (764 cases) admitted before July 2006 were set as the control group,while those after July 2006(772 cases) were set as the observation group. The observation group received a series of measures for protection from hypothermia besides of routine perioperative nursing.The control group only adopted routine perioperative nursing.The SSI rate was compared between the two groups. Results The SSI rate of the observation group was lower than that of the control group(P < 0.01 ). Conclusions Incidence of periop-erative hypothermia in patients undergoing gastroenteritic operation can increase the SSI rate.Appropriate measures for protection from hypothermia can prevent the incidence of hypothermia as well as SSI.

Objective To explore the change of serum zinc level of children with rotavirus(RV) enteritis and efficacy of zinc supplementation on children with rotaviral enteritis.Methods One thousand one hundred and eighty-three healthy children were enrolled in this study,who were divided into different groups,and the zinc levels of children in every different age group were detected.These levels were used as normal levels of children in Dongguan district.One hundred and forty-three diarrhea patients in this 2 years were enrolled.Confirmed dia-gnosis was depended on the RV test in patients′ stool.The children with diarrhea were randomly divided into zinc treatment group (n=72) and conventional therapy group (n=71).The serum zinc levels in RV enteritis was analyzed.The patients in conventional therapy group were received diarrhea conventional therapy inchuded smectite and fluid infusion and so on;in addition to diarrhea conventional therapy,zinc gluconate 20 mg/d (10 mg/d below 6 months of age) for successive 14 days were given the patientsin zinc treatment group.The different efficacy of the 2 groups and the changes of serum zinc in treatment group were analyzed.Results Compared with normal children,the ones suffering from RV enteritis had lower serum zinc level(P0.05).Conclusions The ones suffering from RV enteritis have lower serum zinc level.In addition to diarrhea conventional therapy,giving zinc treatment has better effect on enhancing curative effect of RV enteritis.On the other hand,the suggestion of zinc supplement made by WHO is also suitable for Chinese children.

Objective:To study effect of health education on blood pressure control in patients with hypertension through community survey and perform health education.Methods:Residents from Datang street community re-ceived systematic sampling and questionnaire.A total of 490 patients with hypertension detected during census were regarded as subjects,and they were randomly divided into routine treatment group (n=240)and health education group (n=250).Health education group received health education,and effects were compared between two groups. Results:Compared with routine treatment group after intervention,there were significant rise in awareness rate of preventive and therapeutic knowledge [diagnostic value of hypertension (49.17% vs.58.40%),risk factors of hy-pertension (30.41% vs.58.00%),antihypertensive medication (58.75% vs.79.60%)]and control rate of blood pressure (23.33% vs.60.80%),and significant reduction in blood pressure [(147.68±13.97)/(89.30±12.43)mm-Hg vs.(143.57±13.53)/(85.73±11.54)mmHg]in health education group,P<0.05 or<0.01. Conclusion:Carry-ing out targeted health education possesses active significance for prevention and treatment of hypertension.

Objective To explore the effect of diammonium glycyrrhizinate(DG) and astragalus membranaceus (AM) injection on the clinical comprehensive score in patients with acute lung injury (ALI). Methods According to the random number table method,a prospective random controlled study was conducted in which 60 cases of patients with ALI were divided into a study group and a control group(each,30 cases). Both groups received a comprehensive treatment based on the new guidelines,and the study group was additionally given DG and AM injection(DG 150 mg+AM 20 ml)one time per day for 7 days. The scores of lung injury,acute physiology and chronic health evaluationⅡ(APACHEⅡ)and systemic inflammatory response syndrome(SIRS)were measured at baseline,3rd and 7th day after treatment,and ventilation support time and final disease mortality rate were also calculated in all the patients. Results There were no statistically significant differences between the two groups in the scores of lung injury,APACHEⅡand SIRS before treatment and after treatment for 3 days(all P>0.05),with prolonged treatment,the above indexes were significantly reduced compared with those before treatment in the two groups,and the decreases in scores of indexes in study group was more significant than those in control group after treatment(lung injury score:1.31±0.99 vs. 2.29±1.08,APACHEⅡscore:18.43±8.17 vs. 24.23±6.98,SIRS score:1.69±0.89 vs. 2.60±1.04,all P<0.01). The time(hour)for ventilator support in study group was shorter than that in the control group(176.10±57.81 vs. 286.07 ± 156.27,P<0.01),but there was no statistically significant difference in mortality rate between the two groups(13.33%vs.16.67%,P>0.05). Conclusion The results suggest that DG and AM injection improve the scores of lung injury,APACHEⅡand SIRS,and alleviate the lung injury,so that the injection is beneficial to the early weaning from the ventilator to support treatment in patients with acute lung injury,and has certain therapeutic effect on ALI.

Objective To evaluate the predictive value of modified early warning score (MEWS) and SMART-COP score on mechanical ventilation in patients with severe influenza A H1N1. Methods Fifty cases diagnosed with severe influenza A H1N1 were retrospectively analyzed. The MEWS and SMART-COP score were calculated. The area under the receiver operating characteristic (ROC) curve (AUC) was evaluated using ROC curve. MEWS, SMART-COP score and AUC were analyzed by Z test. Results The AUCs of MEWS and SMART-COP score for predicting mechanical ventilation were 0. 923 and 0. 889, respectively, which were not significantly different (Z=0. 548, P =0. 584).Conclusion Both of MEWS and SMART-COP score are predictive factors of mechanical ventilation in the patients with severe influenza A H1N1.

To evaluate the status of diabetes-related knowledge and training requirement among general physicians,a questionnaire survey was conducted in 676 general physicians from 32 primary medical institutions and 5 secondary hospitals of Shanghai Pudong New Area.48.2% (261/541) of the surveyees had bachelor degree and most of them worked in secondary hospitals or primary medical institutions in affluent areas.The awareness rate of diabetic knowledge among the surveyeos was 51.6%,and there were significant differences in the awareness rate of diabetes-related knowledge between different levels of hospitals and physicians with different academic background.Only 26.6% of physicians received diabetes-related continuing education or training,there was a popular request for professional training from the surveyed physicians.
