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 evaluate the therapeutic effect of ESWL combined with urinary stone decoction and ear acupoint pressure for the patients with renal and ureteral calculi.Methods A total of 110 patients with renal and ureteral calculi were randomly divided into the Chinese medicine (CM) and conventional groups, 55 in each group. Both groups were given ESWL treatment as basic treatment. Chinese medicine group were given the urinary stone decoction and auricular acupressure, and the conventional group used stone granules. Both groups were treated for 2 weeks. According to the photography of ultrasound, the changes of calculi, time of lithagogue, pain relief after operation and the effect rates of pain relief on abdomen and waist, of remission of haematuria, and of urinate pain. ResultsAfter treatment, the successful rates of operation in the CM group was 90.9% (50/55), and conventional group was 76.4% (42/55). There was significant difference between 2 groups (χ2=4.251,P=0.009). The time of stone removal in CM group was significantly shorter than that in the conventional group (7.3 ± 3.8 dvs. 11.2 ± 4.3 d,t=4.032,P<0.001). After 1st, 3rd, 5th, 7th days, the VAS pain scores in the CM group were significantly lower than those in the conventional group (4.1 ± 0.8vs. 5 ± 1.2,t=4.783;4.5 ± 0.9vs. 5.3 ± 1.3,t=4.492; 3.8 ± 0.8vs. 4.5 ± 0.8,t=4.503; 2.2 ± 0.8vs. 2.9 ± 0.9,t=3.691; allP<0.01). After 7th day, the rates of abdominal pain relief was 60% (33/55), pain relief was 79.1% (34/43), the remission of hematuria was 81% (17/21) in the CM group, and the control group were 40% (22/55), 59.6% (28/47), 52% (13/25). There were significant differences between 2 groups on these indices (χ2 values were 4.400, 3.982, 4.217,P values were 0.036, 0.046, 0.040).Conclusions The ESWL combined with urinary stone decoction and ear acupoint pressure could improve the symptoms of patients with kidney ureteral stones.

OBJECTIVE:To study the antitumor mechanism of Ruixiang Langdu(Stellera chamaejasme L ) abstracts(SCA) METHODS:SCA-contained serum was derived from mice pre-administrated with different oral dosages of SCA and at different times after administration The effects of the serum on the proliferation of K562 leukemic cells were observed with MTT assay and clone formation RESULTS:After mixing with the SCA-contained serum derived at 1,2,4,8h after giving SCA(3,6 and 12g/kg),the rates of MTT transformation and clone formation of K562 cells were decreased significantly The SCA-contained serum 12 h after giving drug was more effective than others CONCLUSION:The SCA-contained serum inhibited the proliferation of tumor cells,which may be one of its important antitumor mechanism

Traumatic coagulopathy is a serious complication of tissue damage caused by trauma.In clinic,it easily develops into multiple system organ failure and results in high mortality.Traumatic coagulopathy is a plurality of blood coagulation disorder,its pathogenesis is extremely complex and involves tissue damage,blood coagulation,anticoagulation and fibrinolysis,inflammation and many other pathophysiological aspects.An in-depth study on the pathogenesis of traumatic coagulopathy is very important to improve clinical effect.This paper tries to do a review of recent study progress from pathophysiological mechanisms and hopes to provide reference for clinical work.

Objective To explore the clinical characteristics of eosinophilic gastroenteritis. Methods The clinical data of 2 children with eosinophilic gastroenteritis was retrospectively analyzed. Results Eosinophilia was found in both cases and path-ological examination indicated eosinophil infiltration in intestinal mucosa. The clinical symptoms were improved after hypoaller-genic diet, amino acid formula and anti-allergy treatment. Conclusions Eosinophilic gastroenteritis is characterized by eosino-phil infiltration with unknown pathogenic factor leading the treatment of eosinophilic gastroenteritis lacking of sound evidence.

Physical training induces beneficial adaptations,but long excessive exercise may lead to severe damage to the skeletal muscles,liver,heart,kidneys and immune functions. Over the past few decades,health scholars have been searching for natural components that can prevent or improve the damage induced by hyperkinesis. The mechanisms of organ damage induced by long overtraining include immunosuppression,metabolism disorder,hormone disturbance,oxidative damage, etc. Natural poly-saccharides have interventional effects on these injuries,possibly by improving immunity,regulating metabolism and ameliorating free radical damage.

Objective To study complement receptor typeⅠ(CR1)activity of erythrocytes in pa-tients with SLE.Methods Using polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP),CR1rosette(RBC-CR1R)and immuno-complex rosette(RBC-ICR)on red cell,the ery-throcyte complement receptor I type(ECR1)genomic density polymorphism(HH type,HL type,LL type)and erythrocyte CR1immune activity were determined in32patients with SLE and in48normal individuals.Results It was found that HH type rate of ECR1density polymorphism in patients with active SLE was significantly lower(10/16,62.5%)than that(13/16,81.3%)in patients with stable SLE.The level of CR1immune activity in HH type was significantly higher than that in HL,LL type of SLE,and significantly dif-ferent from that in48normal individuals(P
