Objective To explore the diagnostic value of hysteroscopy and transvaginal B-type ultrasound in endometrial polyps.Methods Eighty cases of endometrial polyps in our hospital from August 2015 to August 2016 were selected as the research subjects.Firstly,the patients were performed the transvaginal B-type ultrasound examination and then the hysteroscopic examination was conducted.The examination results of the two methods were observed.Results After hysteroscopic examination,75 cases were diagnosed as endometrial polyps,5 cases were misdiagnosed as other diseases.In the transvaginal B-type ultrasound examination,52 cases were diagnosed as endometrial polyps and 6 cases were misdiagnosed as other diseases.The detection rate had statistically significant difference between hysteroscopy and B-type ultrasound examination (P<0.05);the minimum was at least 1 endometrial polyp and the maximum were 4 endometrial polyps, including 21 cases of 1 endometrial polyp,36 cases of 2 endometrial polyps,14 cases of 3 endometrial polyps and 9 cases of 4 endometrial polyps.The hysteroscopic examination accurately detected 21 case(100.00%) of 1 endometrial polyp,34 cases (94.44%) of 2 endometrial polyps,12 cases (85.71%) of 3 endometrial polyps and 8 cases (88.89%) of 4 endometrial polyps;the transvaginal B-type ultrasound accurately detected 13 cases (61.90%) of 1 endometrial polyp, 17 cases (47.22%) of 3 endometrial polyps,11 cases (78.57%) of 3 endometrial polyp and 5 cases (55.56%) of 4 endometrial polyps,there were statistically significant differences in the distribution between the two examination methods (P<0.05),moreover hysteroscopy had higher accuracy.Conclusion The diagnosis efficiency of hysteroscopy in diagnosing endometrial polyps is significantly better than that of B-type ultrasound.

OBJECTIVE:To explore the effects of ursodeoxycholic acid and adenosine methionine combined with polyene phos-phatidylcholine on related indicators of pregnancy with intrahepatic cholestasis(ICP). METHODS:Medical information of 90 ICP female were analyzed retrospectively and divided into control group(45 cases)and observation group(45 cases)according to drug use. Control group was given Ursodeoxycholic acid tablet 300 mg orally,3 times a day+Transmetil for injection 1 g added into 5%Glucose injection 250 mL intravenously,once a day. Observation group was additionally given Polyene phosphatidylcholine injec-tion 15 mL added into 5% Glucose injection 250 mL intravenously,once a day,on the basis of control group. Treatment course of 2 groups lasted for 2 weeks. The itching score,the levels of serum total bile acid(TBA),ALT and AST,pregnancy outcome and the occurrence of ADR were observed in 2 groups before and after treatment. RESULTS:Before treatment,there was no statistical significance in itching score,the levels of TBA,ALT and AST between 2 groups (P>0.05). After treatment,itching score,the levels of TBA,ALT and AST in 2 groups were significantly lower than before treatment,and the observation group was significant-ly lower than the control group,with statistical significance (P<0.05). The cesarean section rate,premature birth rate,fetal dis-tress rate and amniotic fluid rate of observation group were significantly lower than those of control group,with statistical signifi-cance(P<0.05). No obvious ADR was found in 2 groups during treatment. CONCLUSIONS:Ursodeoxycholic acid,ademetionine combined with polyene phosphatidylcholine can effectively alleviate itching symptoms,liver function and pregnancy outcome of ICP patients,with good safety.

Facing current situation of integrative medicine (IM), authors put forward that clinical and diagnosis program of IM could be carried out from clinical path, pathogenesis, treatment theory and philosophy, and so on, but with different integration degrees. Meanwhile, formulation of concrete program should be disease-targetedly set up, and adjusted from person to person, from place to place, from time to time. As for settled IM program , authors could evaluate it from whether Chinese medicine and Western medicine have formed complementary, synergistic, excitatory actions, and toxicity attenuation; whether more problems could be solved in efficacy, safety, practicability, and economy than previous single mode.

Objective To explore the association between epidermal growth factor receptor (EGFR) mutation subtypes and the prognosis of brain metastasis in patients with lung adenocarcinoma.Methods A retrospective analysis was performed on the clinical data of 256 patients who were admitted to our hospital and confirmed with brain metastases of lung adenocarcinoma by EGFR mutation detection from 2010 to 2015.The prognostic factors for brain metastases were analyzed.The survival rate was calculated by the Kaplan-Meier method and analyzed by the log-rank test.The univariate and multivariate prognostic analyses were performed by the log-rank test and the Cox proportional hazards model.Results The median survival time was 10.13 months in all patients.The univariate analysis showed that sex,EGFR mutation status,exon 19 deletion,the Karnofsky Performance Status (KPS) score of brain metastases,and targeted therapy were prognostic predictors (P=0.006,0.001,0.010,0.000,0.003).The multivariate analysis showed that the KPS score and exon 19 deletion were prognostic factors for brain metastases (P=O.000,0.045).When grouped into the recursive partitioning analysis classes,all the patients were split into three subgroups with significantly different prognosis (P =0.000).Conclusions Exon 19 deletion is a prognostic predictor of brain metastases in patieuts with lung adenocarcinoma,which can be integrated into the prognosis scoring system for brain metastases of lung adenocarcinoma.EGFR tyrosine kinase inhibitors improve the survival in patients with brain metastases of lung adenocarcinoma and EGFR mutation,particularly,in those with exon 19 deletion.

Objective To study the effects of preconditioning treadmill exercise on excitatory amino vacid changes in rats after the cerebral infarction and the protective effects against cerebral isehemia brain injury. Methods Thirty Sprague-Dawley rats were used in this study. Twenty-five rats were subject to an operation to establish the animal model of middle cerebral artery occlusion and divided into a isehemia group, an 1-week ex- ercise group (trained in the 4th week) , a 2-week exercise group (trained in the 3rd and 4th weeks) and a 4- week exercise group (trained for 4 weeks) , while the remaining 5 rats were subject to sham operation, and served as the controls. After 4 weeks of experiment, all the the rats were fixed on stereotactie apparatus for the brain microdialysis of the striatum. Then the focal middle cerebral artery ischemia and reperfusion were made with thread oeclussion in rats and microdialysis technique was used to collect extraeellular fluid in each period of pre-ischemia, ischemia (40, 80 and 120 min), and reperfusion (40, 80, 120, 160, 200 and 240 min) to detect the changes of the excitatory amino acid. At the same time the infarction volume was also measured at 24 hours after ischemia-reperfusion of the brain. Results The difference between any two groups was significant with regard to the volume of cerebral infarction (P < 0.05). Two weeks and four weeks of the preconditioning treadmill exercise couled significantly reduce concentration of Glu excessively released due to the ischemia (P < 0.01). Conclusion At least two weeks of preconditioning treadmill exercise can inhibit the excessive release of the important excitatory amino acid neurotransmitter glutamate, to some extent, in the process of the subse- quent ischemic brain injury and during reperfusion, which might be one of the protective mechanisms of move- ment against the early isehemie brain injury.

Objective To investigate the clinical value of circumferential strain and strain rate in estimating the carotid elasticity. Methods Thirty-five consecutive patients of hypertension were enrolled in this study as the patient group and 36 healthy volunteers whose ages were matched with the patient group were included as controls. The intima-media thickness(IMT) of common carotid arteries of both the patients and controls were measured using RF-Data technique of ultrasound vascular measurement and the following traditional parameters reflecting common carotid elasticity were obtained: pulse wave velocity (PWV),arterial compliance (AC). While the new parameters reflecting vascular strain including endovascular longitudinal strain(EN-LS), endovascular circumferential strain(EN-CS), endovascular longitudinal strain rate(EN-LSR) ,endovascular circumferential strain rate(EN-CSR), adventitial longitudinal strain(EP-LS),adventitial circumferential strain ( EP-CS ), adventitial longitudinal strain rate ( EP-LSR ), adventitial circumferential strain rate(EP-CSR) were collected using the technique of X-strain. All the corresponding parameters were compared between hypertensive group and controls. The correlations between elasticity and hemodynamic parameters were analyzed. Results In the hypertension patients,PWV was higher while AC,EN-CS,EN-CSR,EP-CS and EP-CSR were lower than that of the control group( P ＜0.05). No significant differences were detected in the longitudinal strain and strain rate. In the hypertension group,AC correlated positively with PWV, while EN-CS, EN-CSR, EP-CS and EP-CSR correlated negatively with PWV and positively with AC. Conclusions Circumferential strain and strain rate conform well to the mechanical principle and the characteristic anatomic and histological structure of the vessels and may be used to reflect the early changes of the vascular elasticity.

DNA microarrays have been acknowledged to represent a promising approach for the detection of viral pathogens. However, the probes designed for current arrays could cover only part of the given viral variants, that could result in false-negative or ambiguous data. If all the variants are to be covered, the requirement for more probes would render much higher spot density and thus higher cost of the arrays. Here we have developed a new strategy for oligonucleotide probe design. Using type I human immunodeficiency virus (HIV-1) tat gene as an example, we designed the array probes and validated the optimized parameters in silico. Results show that the oligo number is significantly reduced comparing with the existing methods, while specificity and hybridization efficiency remain intact. The adoption of this method in reducing the oligo numbers could increase the detection capacity for DNA microarrays, and would significantly lower the manufacturing cost for making array chips.

OBJECTIVETo explore types of organic components and pollution level of di-n-butyl phthalate (DBP) between human milk and cow milk products.

METHODSForty healthy postpartum women with an average age of (27.44 ± 3.43) years old were selected, and a 5 ml sample of breast milk were collected. Four different brands of fresh cow milk and 1 brand of milk powder were randomly selected in the market. A total of 15 samples were collected with 3 from each brand, and the qualitative analysis of types of organic components and quantitative analysis of DBP were conducted by gas-chromatography and mass-spectrometry (GC/MS) method.

RESULTSA total of 176 different types of organic components were detected in 40 samples of human milk (averaged at (10.58 ± 4.16) types per sample); 37 different types were detected in 12 samples of fresh cow milk (averaged at (8.67 ± 1.61) types per sample); while 31 types of organic components were detected in 3 samples of milk powder (averaged at (12.67 ± 0.58) types per sample). It was obvious that the types of organic components in milk powder were significantly higher than the other two groups (t = 2.09, 4.00, P < 0.05). The most frequent organic component in human milk and cow milk was 9-octadecenoic acid (45.00% (18/40) in human milk; 53.33% (8/15) in cow milk). DBP concentrations were (57.78 ± 35.42) µg/L, (20.76 ± 6.60) µg/L and (0.45 ± 0.05) mg/kg (equal to (66.78 ± 7.60) µg/L) in human milk, fresh cow milk and milk powder, respectively. The DBP concentration in fresh cow milk was significantly lower than those in human milk and milk powder (t = 37.02, 46.02, P < 0.05).

CONCLUSIONBoth human milk and cow milk contain different types of organic pollutants, some of which have toxic effects on reproduction and human development.
