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.

Objective To evaluate the value of 128-slice CT on locating the obstruction site of the upper airway in obstructive sleep apnea hypopnea syndrome (OSAHS)patients by three-dimensional reconstruction technology.Methods There were 52 patients with OSAHS diagnosed by the PSG and 32 cases of healthy volunteers in our hospital.All objects were performed 128-slice CT scan of the upper airway during awake state,and those patients’upper airways were scaned on Muller test.The airway volume of the ret-ropalatal region,retroglottal region and epiglottal region,and the total length of upper airway were measured,and statistical analysis of the each index was obtained.Results During awake state,compared with the control group,the length of upper airway in OSAHS patients increased significantly(P <0.001).Compared with the awake state,OSAHS patients’airway volume of the retropalatal region, retroglottal region and the total airway volume on the Muller test were reduced significantly(P <0.001).OSAHS patients’upper air-way length was correlated negatively to the average MSaO 2 (r=-0.33,P <0.05).Conclusion The three-dimensional reconstruc-tion of upper airway on 128-slice CT can evaluate the position and degree of the obstruction site in OSAHS patients’upper airway better,which has important significance to guide clinical treatment.

Objective To summarize the clinical features of the pancreaticopleural fistula (PPF) in children in order to improve the understanding of PPF and to make early diagnosis and treatment of the disease.Methods Five cases of pediatric PPF in Beijing Children's Hospital Affiliated to Capital Medical University from December 2007 to March 2014 were studied by retrospective analysis.The clinical features, laboratory results, image characteristics, treatment and prognosis were reviewed.Results Five cases of PPF were diagnosed aged between 2 years to 10 years and 5 months old, history from more than 1 month to 6 months.The main symptoms were chest tightness (3 cases), chest pain (3 cases) , fever(3 cases) , wheeze (1 case) , dyspnea (1 case).Only 1 case was with abdominal pain and abdominal distension when he was admitted to hospital.All patients had massive pleural effusions, included right side (3 cases),left side(1 case) ,bilateral sides(1 case), 1 case complicated with massive ascites.Pleural fluid amylase of all the cases was significantly elevated (＞ 1 000 U/L) ,the highest was more than 50 000 U/L.Four cases had positive findings of pancreas by transabdominal ultrasound.Five cases had morphological changes in pancreas by magnetic resonance cholangiopancreatography (MRCP).Four cases had PPF and pancreatic pseudocysts respectively.Conservative treatment was given to 5 cases, but further 3 cases reveived stent insertion by endoscopic retrograde cholangiopanereatography, and 2 cases reveived surgical therapy.Conclusions PPF is rare in children, the main clinical feature is massive pleural effusion with respiratory symptoms.Pleural fluid amylase would be significantly elevated.The diagnosis of PPF generally relies on imaging, MRCP is considered the imaging study of choice for PPF due to its superiority in identifying a fistula in the pancreatic region and its noninvasiveness as compared to endoscopic retrograde cholangio pancreatography.Endoscopic and surgical therapy can be used if internal therapy is not satisfactory.

Objective To discuss the clinical diagnostic and guiding treatment value of changed positions of hyoid bonein the upper airway of patients with obstructive sleep apnea hypopnea syndrome. Methods 128-slice computed tomography was performed for 52 patients with severe OSAHS and 32normal healthy people to measure thehyoid bone in the upper airway in sober state and Muller maneuver. The correlationsbetweenthese indexes were analyzed under linear relation. Results (1)In comparison of the Muller maneuver with sober state , chinnodules and palatal plane to the hyoid in the OSAHS group were statistically higher than the healthy controlgroup (P < 0.001). (2)The distance of hyoid to chinnodules in the OSAHS group was significantlylonger and greater than that of the healthy control group (P < 0.001).(3)The distance of palatal plane to the hyoid was positively correlated with AHI , while thedistances of palatal plane andchinnodules to the hyoidwere both negatively correlated with MSaO2. Conclusion The changes ofhyoid positionare indicative for the clinical diagnosis and is helpful for the guidance of clinical treatment of OSAHS.
