OBJECTIVE:To observe the efficacy and safety of ferrous succinate in the treatment of pregnancy complicated with iron deficiency anemia. METHODS:90 pregnant women with iron deficiency anemia were randomly divided into treatment group and control group. All patients were stopped drugs related to iron supplement 2 weeks before treatment,and the blood index-es were detected,including red blood cell count (RBC),hemoglobin concentration (Hb) and serum ferritin concentration (SF), etc. The treatment group was orally given 2 Ferrous succinate tablets after a meal,twice a day;control group was orally given 2 Ferrous sulfate tablets after a meal,twice a day. The treatment course for both groups was 1 month. The clinic data was observed, including clinical efficacy,RBC,Hb and SF level before and after treatment,and the incidence of adverse reactions. RESULTS:The total effective rate in treatment group was significantly higher than control group,the difference was statistically significant(P<0.05). After treatment,the RBC,Hb and SF level in 2 groups were significantly higher than before,and treatment group was high-er than control group,the differences were statistically significant(P<0.05). The difference was not statistically significant in the in-cidence of adverse reactions(P>0.05). CONCLUSIONS:Ferrous succinate tablets has good efficacy and safety in the treatment of pregnancy complicated with iron deficiency anemia.

Objective To investigate the effects of Arctigenin ( ATG ) on concanavalin ( ConA )-stimulated cell proliferation and cytokine secretion in mouse spleen cells, and its possible mechanism. Methods The toxicity of ATG on mouse spleen cells was determined by MTT assay. The inhibition of proliferation was investigated by tritiat-ed thymidine incorporation method. Secreted cytokines (IFN-γand IL-2) were analyzed by ELISA. The associated proteins and phosphorylation levels of mTOR pathway ( mTOR/P70 S6 K/Akt/AMPK/Raptor ) were detected by Western blot. Results ATG had no significant toxicity to mouse spleen cells. ATG significantly inhibited mouse primary spleen cells proliferation induced by ConA. ATG suppressed IL-2 and IFN-γ production of mouse spleen cells in a concentration-dependent manner. ATG remarkably suppressed the phosphorylation of mTOR and P70S6K, and enhanced the phosphorylation of upstream AMPK and Raptor, while the phosphorylation of Akt did not change significantly. Conclusion ATG markedly suppresses the proliferation of mouse spleen stimulated by ConA cells and secretion of IFN-γand IL-2 , which may be correlated to the abilities of enhancing the phosphoryla-tion of AMPK and Raptor, inhibiting the phosphorylation of mTOR and P70S6K.

Objective To study the prognosis of gastroesophageal reflux disease ( GERD) in children, and explore the factors which impacts on the prognosis of GERD. Methods One hundred and thirteen children with GERD were enrolled on the basis of positive result of 24-hour pH-monitoring between January 2007 and November 2011. The number of patients who were followed up was 87,and the parents of children were contacted with the telephone. The prognosis was evaluated by comparing the degree of patients′symptom relief,and the cumulative symptom relief rate was calculated by Kaplan-meier product limit method. The univariate Log-rank test and the COX proportional hazardmodel multivariate analysis were applied to detect the factors impacting on the prognosis,including age,gender,the regularity of treatment,reflux index,and Boix-Ochoa standard score,with esophageal hiatal hernia or without,receiving surgical treatment or not,the diet and lifestyle improved or not,receiving anti-acid treatment or not,as well as with allergies his-tory or without. Results At last,76 out of 87 children had symptom relieved. Survival curve showed the cumulative symptom relief rate at different time points,the median cumulative symptom relief rate reached 6 months,the final relief rate was close to 90. 0%,and the continuous treatment time was 44 months. The study showed that 14. 9% (13/87 ca-ses) of children′s growth and development were affected and the life and learning in 16. 1% (14/87 cases) of children were impacted. Age (P=0. 012,Wald=6. 376) and the regularity of treatment (P=0. 000,Wald=13. 059) were the risk factors in the prognosis of GERD. Conclusions Age and the treatment regularity were the factors in the prognosis. The children aged more than 1-year old have poor prognosis compared with those less than 1-year old,and the irregular treatment is the risk factor in the prognosis.

Real-time quantitative RT-PCR was performed to evaluate mRNA production of CNGA2 subunits. RESULTS In Dexamethasone-injected rats, the up-regulation of CNGA2 mRNA was observed in 2-weeks group(P

OBJECTIVE: To discuss the soft palate, hard palate and mandibule for the pathogenesis and clinical treatment of patients who have obstructive sleep apnea hypopnea syndrome. METHOD: There were 52 patients with OSAHS diagnosed by the PSG and 32 cases of normal healthy volunteers in our hospital. All objects were given 128 slice spiral CT scan of the upper airway. We measured the related indexes of the soft palate, hard palate and mandible, then analysed statistical differences between them and did Pearson correlation analysis with apnea hypoventilation index (AHI), average blood oxygen saturation (MSaO2) in PSG. RESULT: Compared with the control group, the soft palate length [(37.93 ± 5.20)mm VS (33.52 ± 4.25)mm] and the distance between mandible with cervical vertebra [(75.00 ± 7.10)mm VS (69.93 ± 5.58)mm] increased significantly, but the distance of trailing edge of hard palate to inferior margin of slope significantly reduced [(42.57 ± 4.52)mm VS (45.80 ± 2.94)mm, P < 0.01] in patients with OSAHS. Each measurement associated with AHI and MSaO2 had no significant correlation (P > 0.05). CONCLUSION The soft palate, hard palate and mandibular are some of the important risk factors of OSAHS, and they also have reference value for the choice of clinical treatment operation. Preoperative CT examination can offer help in the treatment of OSAHS.
