OBJECTIVE:To observe clinical efficacy of carboxymethyl starch in the treatment of recurrent respiratory infection (RRI)children. METHODS:110 RRI children were selected and randomly divided into observation group and control group,with 55 children in each group. Control group was given routine treatment,such as anti-infection,anti-virus,abatement of fever,reliev-ing cough,phlegm transformation and etc. Observation group was additionally given Carboxymethyl starch sodium solution (7 ml for <4 year-old,10 ml for 4-7 year-old,15 ml for >7 year-old)on the basis of control group. Both groups received consecutive treatment for 3 months. The changes of cellular immunity function index CD4+,CD8+ and CD4+/CD8+ and humoral immunity index IgG,IgA and IgM were observed in 2 groups before and after treatment,and clinical efficacy was evaluated in 2 groups. RE-SULTS:There was no statistical significance in CD4+,CD8+and CD4+/CD8+levels of control group before and after treatment(P>0.05);after treatment,CD4+ and CD4+/CD8+ of observation group obviously increased,while CD8+ level obviously declined;the observation group was better than control group,with statistical significance (P<0.05). There was no statistical significance in IgG,IgA and IgM levels of control group,with statistical significance (P>0.05);after treatment,IgG,IgA and IgM levels of control group increased significantly,and the observation group was better than control group,with statistical significance (P<0.05). Total effective rate of observation group was 92.73%,which was much higher than that in control group (78.18%),with statistical significance(P<0.05). CONCLUSIONS:Carboxymethyl starch has definite therapeutic efficacy on RRI,and can obvi-ously improve cellular and humoral immunity function.

Objective To assess the diagnostic value of Logistic model in differentiating between malignant and benign ovarian lesions. Methods Thirty-five indexes of clinical and ultrasound data were recorded in 601 ovarian lesions confirmed by surgical pathology. The Logistic model was developed on a training set( n - 400) and tested on a test set( n = 201). Results Variable selection resulted in a set of 10 variables for the models: personal history of ovarian cancer, maximal diameter of the lesion, maximal diameter of the solid component, multilocular-solid tumor, solid tumor, ascites, flow within papillation, irregular walls, very strong intratumoral blood flow (i. e. color score 4) and acoustic shadows. Test set area under the receiver-operating characteristics curve was 0.963 with a sensitivity 93.9% and a specificity 93. 1 %. Conclusions Logistic model can accurately separate malignant from benign ovarian masses.

AIM To investigate whether ginsenoside Rg1 can reverse chronic lead-induced impairment of long-term potentiation (LTP) in the CA1 region of rat hippocampus. METHODS Neonatal Wistar rats were exposed to lead from parturition to weaning via milk of dams whose drinking water (20 mL per day) contained 0.2% lead acetate. Field excitatory postsynaptic potentials (fEPSP) were recorded and LTP was induced in the CA1 region in rat hippocampal slices on postnatal 20-25 d. RESULTS In hippocampal slices from both control and lead-exposed rats, perfusion with ginsenoside Rg1 50 μmol·L-1 for 20 min induced enhancement of fEPSP (LTP), while the amplitude of LTP in lead-exposed rats was lower than that of controls. In hippocampal slices from chronic lead-exposed rats, LTP induced by high-frequency stimulation (HFS, 1s, 100 Hz) was significantly reduced, while perfusing with ginsenoside Rg1 (50 μmol·L-1) for 20 min increased the amplitudes of LTP induced by HFS by 47.1%. CONCLUSION Rg1 can increase basic synaptic transmission and partially reverse chronic lead-induced impairment of HFS-LTP.

Objective To explore the association between HbA1c and acute myocardial infarction(AMI) in youth. Methods Seventy-two AMI patients (≤44y) diagnosed during the period from January in 2009 to August in 2012 were enrolled and 79 young age-matched adults without coronary artery disease at the same period were enrolled to be control group. The relationship between HbA1c, fasting blood-glucose(FBG) and AMI was explored. Results (1)Compared with the control group,the plasma FBG and HbA1C value were significantly higher(P<0.05) in AMI group. (2)Logistic regression analysis showed that HbA1c is the independent risk factor for AMI in youth. (3)In AMI group, the HbA1c level in single vessel disease had remarkable difference with that in double vessel disease and triple vessel disease(P<0.05). Conclusions Increasing HbA1c level is the independent risk factor for AMI in youth,and positively correlated with the degree of coronary artery lesions. Primary intervention of glycometabolism abnormality possibly becomes the new opinion for prevention and cure of AMI.
