Objective To investigate the effects of three external nasogastric tube fixations on unplanned nasogastric tube removal after radical esophagectomy for esophageal cancer.Methods Two hundred and thirty four esophageal cancer patients who underwent radical esophagectomy with nasogastric intubation were assigned into conventional group I(n=74),conventional group II (n=79)and experiment group(n=81)using random number table.For external fixation of the nasogastric tube,the traditional group I used“3M”silk tape,the traditional group II used a white flat strap with two knots and the experiment group used anI-shaped nasal fixation tape combined with a flapping cheek fixation tape.The three groups were compared in terms of displacement of the indwelling nasogastric tube and slippage of the tube.Results The displacement rate of nasogastric tube and the rate of slippage in the experiment group were both significantly lower than those in both conventional groups I and II(all P<0.05).Conclusion TheI-shaped nasal fixation tape combined with a flapping cheek fixation tape in fixing the nasogastric tube can effectively reduce the incidence of unplanned removal of nasogastric tube and meanwhile the patients may feel comfort and satisfactory.

Objective To investigate the efficacy of progressive resistance exercise for improving the lower limb motor function of hemiplegic stroke patients. Methods Eighty-nine hemiplegic patients were randomly divided into a treatment group (n =46) and a control group ( n = 43 ) . Both groups received routine rehabilitation training, while the treatment group also undertook progressive resistance training. The control group received extra quadriceps femoris training. Before and after the treatment, motor function was evaluated with the Fugl-Meyer lower limb assessment, functional ambulation category (FAC) classification and the modified Barthel index (MBI). Results Before intervention, there were no significant differences between the two groups in any of the assessments. Four weeks later, all the assessment scores obtained with the Fugl-Meyer lower limb assessment, FCA classification and MBI in the treatment group were significantly better than those in the control group. Conclusion Progressive resistance training combined with routine rehabilitation treatment can improve motor function in the lower limbs, ambulation and ability in the activities of daily living of hemiplegic patients after stroke.

Aim The current study was conducted to investigate the effect of GSTP1 codon 105 polymorphism, alone and in combination with GSTM1-deletion polymorphism, on erythrocyte GST activity in 196 Han Chinese. Methods GST activity was measured in healthy Chinese by a spectrophotometric method (n=196;101 males and 95 females; age range 21～81 years; median 43.5 years). GSTM1 polymorphisms were analyzed by a PCR-Multiplex procedure, whereas GSTP1 polymorphism was analyzed by PCR-RFLP. Results The frequency of GSTM1 null genotype was 56.1% and the frequency of I/I, I/V, and V/V genotypes was 60.7%, 35.2% and 4.1%, respectively, in Han Chinese. The mean erythrocyte GST enzyme activity for I/V genotype group(3.53?0.63 U?g -1Hb) was significantly lower than that for I/I genotypes (4.25?1.07 U?g -1Hb, P=0.000), while significantly higher than that for V/V genotypes (2.44?0.67 U?g -1Hb, P=0.004). In GSTM1(-) group, the GST activity of carriers of GSTM1(-)/GSTP1- I/I is significantly higher than that of GSTM1(-)/GSTP1- I/V or-V/V, however, in GSTM1(+) group, there is no difference between different subgroups. There was no significant difference in the mean GST activity among different age groups. Erythrocyte GST activities were significantly higher in females than in males, but not significantly. Conclusion The GST activity measured by CDNB-based assay is probably strongly correlated with the GSTP1 105Val genotype, although other GST enzymes would tend to dilute the GSTP1 genotype effect.

Objective To explore the clinical manifestation of a patient with hypoparathyroidsmsensorineural deafness-renal dysplasia (HDR) syndrome and to sequence the related GATA3 gene of the patient.Methods A 22 year old person with HDR syndrome was reported in regard to clinical manifestation,laboratory examination,and genetic mutation.Some related literatures were reviewed.Results The patient showed tetany,deafness,and positive Chvosteks' and Trousseau' s signs.The initial laboratory studies showed that serum concentration of calcium was lowed and the iPTH level were lower than normal.Binaural pure tone audiometry showed Binaural sensorineural deafness.Colour doppler ultrasound revealed that his right kidney was not observed and the level of creatinine was increased,indicating renal insufficiency.GATA3 mutations on DNA sequence analysis indicated that the 6 exon IVS6-1G-A (G/A heterozygosis splicing),showed the mutation of G to A is in the upstream of the first base in the six exon.After treating with calcium carbonate and vitamin D,the symptoms and signs were improved.Conclusion HDR syndrome is a rare endocrine disease,that should receive more attention in order to avoid missing diagnosis;The IVS6-1G-A as a novel mutation of GATA3 gene,has not been reported so far.

Objective To investigate the expression of serum amyloid A (SAA) in patients adipose tissue with gestational diabetes mellitus (GDM) and the correlations between SAA and insulin resistance (IR) and body mass index (BMI).Methods A total of 60 single full-term pregnant women underwent cesarean section from June 2013 to December 2013 was enrolled in this study (GDM group,n =30;control group,n =30);serum SAA level was detected with Enzyme-Linked Immunosorbent Assay (ELISA);and mRNA expression of SAA1 in adipose tissue was determined by reverse transcription PCR (RT-PCR);SPSS software was used to compare these markers,and the correlations between SAA and HOMA-IR,BMI were analyzed with Pearson correlation method.Results SAA,mRNA expressions in omental and subcutaneous fat in GDM group (0.447 ± 0.069,0.291 ± 0.067) were significantly higher than those in control group (0.194 ± 0.070,0.231 ± 0.068,P ＜ 0.01).Serum SAA levels [(21.038 ± 6.648) mg/L] and homeostasis model assessment of insulin resistance(HOMA-IR) (4.168± 2.416) in GDM group were significantly higher than those in control group [(14.384 ± 12.770) mg/L,2.045 ± 1.008,P ＜ 0.05];SAA1 mRNA expression levels in omental and subcutaneous fat were positively correlated with serum SAA (r =0.353,0.342,P ＜ 0.01).SAA1 mRNA expression levels in omental were positively correlated to pregestational BMI,late gestational BMI,weight gain in pregnancy and HOMA-IR (r =0.543,0.644,0.340,0.473,P ＜ 0.01),and SAA1 mRNA expression levels in subcutaneous fat were positively correlated to pregestational BMI,late gestational BMI,and HOMA-IR (r =0.788,0.693,0.504,P ＜ 0.01),but was no correlation with weight gain in pregnancy(r =0.013,P ＞ 0.05).Conclusions SAA mRNA expressions in omental and subcutaneous fat in GDM group and serum SAA levels increase,which is positively correlated with BMI and the degree of insulin resistance,SAA may participate in the formation of GDM by increasing insulin resistance.SAA may be used as a new monitor of GDM.
