Gestational diabetes refers to the first occurrence or discovery of different degrees of abnormal glucose tolerance during pregnancy, which is one of the most common complications during pregnancy. As the incidence rate increased year by year, the complications of mother and child increased significantly. In recent years, gestational diabetes mellitus has been paid more and more attention. Most of the current researches are about the diagnosis and treatment of gestational diabetes 24 weeks and later, and the theoretical basis for the screening method and treatment of early gestational diabetes is still lacking. With the further understanding of early gestational diabetes mellitus and its adverse maternal and infant pregnancy outcomes, it is imperative to actively carry out the research on the screening and treatment of early gestational diabetes mellitus.

Objective:To explore expression levels of Tim and TLR gene family in children with different types of mycoplasma pneumonia and their clinical significance.Methods: 56 patients with mycoplasma pneumonia were randomly selected in Ji′nan Maternity and Child Care Hospital from March ,2013 to March,2014.All the patients were divided into bronchopneumonia group ( n=40) and segmental pneumonia group (n=16) according to their X-ray manifestations.Bronchopneumonia group was characterized as dot,nodular increased density shadow with or without reticular ,stripe-like interstitial lesion.Segmental pneumonia was described as segmental or lobar consolidation of lung in X-ray.Meanwhile,30 healthy children were involved in control group with matched age and gender.Peripheral venous blood of all the children in every group was collected and total RNA was extracted .The mRNA of Toll-recepter 2,4 and Tim1,3 was quantified by quantitative real-time PCR (qRT-PCR),and compared between different groups.Results:The expression of mRNA of TLR-2,4 and Tim1 significantly increases in both bronchopneumonia group and segmental pneumonia group compared to healthy control.Meanwhile,the mRNA of TLR-2,4 and Tim-1,3 was significantly elevated among segmental pneumonia group compared to healthy control.In addition,the gene expression of Tim1,3 was higher in segmental pneumonia group than broncho-pneumonia group.Conclusion:The TLR-2,4 and Tim1 gene are over expressed in both types of mycoplasma pneumonia and Tim-1,3 are highly expressed in children with severe infection in lung.The expression alteration of TLR-2,4 and Tim1,3 gene is involved in different types of mycoplasma pneumonia.

ve To establish a method for determination of arsenic in drinking water. Methods The contents of arsenic in water samples were determined directly by graphite furnace atomic absorption spectrophotome-try with masking agent of palladium. The working conditions were defined as wave length of 193.7 nm, slit width of 1.3 nm, current of hollow cathode lamp of 12.0 mA; drying 40 sec at 80℃~140℃ ; ashing 20 sec at 1100℃~1200℃; atomizing 5 sec at 2 300℃; purifying 4 sec at 2 600℃ . Results The linear relationship was 10~200?g/ L ar-senic. The average recovery rates of water samples at concentrations of 50 ?g/ L and 150?g/ L arsenic after being added arsenic standard solutions were 100.7% and 103.6% respectively, and sensitivity reached 10?g/ L. The cor-relation coefficient were 0.9954~0.999 7 obtained from 6 randomly repeated determination of standard curve. The metal ions coexisting in determined water samples didn't interfere the determination of arsenic under the application of common uncoated graphite tube. The 0.2% aluminum didn't disturb the determination of arsenic also. Conclusion This method could be applied in the determination of arsenic in water, especially could be applied in the direct deter-mination of arsenic in more clear water samples.

Objective To investigate the curative effect of electromyographic(EMG) biofeedback therapy on spastic diplegia children with cerebral palsy.Methods42 children were divided into the treatment group(n=22) and control group(n=20) randomly.The treatment group was treated with rehabilitation training plus EMG biofeedback training,while the control group with rehabilitation training solely.Manual muscle test(MMT) was performed before and 3 months after treatment,and the treatment group was assessed by electromyographic apparatus additionally.ResultsAfter EMG biofeedback training,the muscular force of children in the treatment group was higher than those in the control group significantly(P<0.05) and the level of root mean square(RMS) and integrated electromyography(iEMG) assessed by surface electromyography(sEMG) increased significantly(P<0.05).ConclusionEMG biofeedback training can provide a satisfactory treatment for spastic diplegia children with cerebral palsy.Electromyographic apparatus is effective to assess muscular force.

Objective To investigate the clinical efficacy and safety of ultra pulse CO2 laser combined with collagen dressing in treatment of cutaneous amyloidosis.Methods A total of 68 cases of primary cutaneous amyloidosis patients according to the different treatment methods was divided into two groups:the control group (n =33 cases) that was given acitretin capsules oral and topical compound flumetasone ointment packet treatment,and observation group (n =35 cases) with ultra pulse CO2 laser combined with collagen dressing external treatment.Two groups were observed in patients with curative effect and adverse reaction.Results Disease of integral observation group after treatment was significantly lower than the control group(t =3.12,P ＜0.05).The observation group had the efficiency of [88.6％ (31/35)] that was significantly higher than that of control group[17/33(51.5％),x2 =11.23,P ＜.0.01].The observation group had significantly shorter healing time [(5.38 ± 1.81) d] compared to the control group [(10.75 ±2.06)d,t =11.39,P ＜ 0.01].The observation group did not have recurrence,which was significantly different from the control group (x2 =4.90,P ＜ 0.05).Conclusions Ultra pulse CO2 laser combined with collagen dressing in treatment of primary cutaneous amyloidosis is a kind of effective treatment methods with remarkable curative effect and less adverse reactions.It is worthy of clinical application.

Objective To compare the risk of tumor invasion and metastasis under paravertebral block (PVB) combined with general anesthesia versus general anesthesia in the patients undergoing radical resection for lung cancer performed via video-assisted thoracoscope in terms of plasma concentrations of vascular endothelial growth factor (VEGF) and matrix metalloproteinase-9 (MMP-9).Methods Forty ASA physical status Ⅰ or Ⅱ patients of both sexes,aged 30-64 yr,with body mass index of 18-25 kg/m2,scheduled for elective radical resection for lung cancer performed via video-assisted thoracoscope,were randomly divided into 2 groups (n =20 each) using a random number table:general anesthesia group (group G) and PVB combined with general anesthesia (group PG).PVB of T4-7 was performed successfully with local injection of 0.375％ ropivacaine 5 ml before induction of anesthesia.Double-lumen endotracheal tube was placed after induction of anesthesia,and the patients were mechanically ventilated.Anesthesia was maintained with inhalation of sevoflurane (end-tidal concentration 1％-2％),and intravenous infusion of remifentanil 0.2-0.3 μg · kg-1 · min-1,and intermittent intravenous boluses of atracurium.Before anesthesia and at 24 h after surgery,the venous blood samples were collected for measurement of plasma concentrations of VEGF and MMP-9.Results The plasma VEGF and MMP-9 concentrations were significantly lower after surgery in group PG than in group G.Conclusion PVB combined with general anesthesia significantly decreases the risk of tumor invasion and metastasis in the patients undergoing radical lung cancer resection performed via video-assisted thoracoscope in comparison to general anesthesia.

Objective To investigate the correlation between augmentation index (AI) of the radial artery and diastolic heart function in patients with hypertension.Methods Echocardiographs were obtained for 305 patients with hypertension.AI,pulse wave velocity (PWV) of peripheral arteries and serum pro-brain natriuretic peptide (proBNP) levels were determined.Correlations and receiver operating characteristic (ROC) curves were drawn between AI values and impaired diastolic function.Results AI levels were significantly increased in patients with impaired diastolic function diagnosed by ultrasound.Assessment of diastolic heart function based on proBNP levels revealed that AI and aortic pulse wave velocity were significantly elevated in patients with impaired diastolic function.The operating curve indicated that AI may be a more accurate and efficient index for the evaluation of impaired diastolic function compared to pWV.Correlation analysis also showed that proBNP levels had altered in parallel with changes in AI and PWV.After adjusting for various factors including age,gender,blood pressure and blood lipid,a positive correlation was observed between proBNP and AI with a correlation coefficient of 0.3697 (P =0.003).However,no correlation between proBNP and aortic PWV was seen after adjustment.Conclusions Changes in radial AI levels may reflect parallel changes in diastolic cardiac function in patients with hypertension,suggesting that AI may be utilized as a non-invasive clinical indicator of diastolic heart function.
