Objective To evaluate the performance of virtual touch tissue quantification imaging (VTQ) for differential diagnosing in uterine hysteromyoma and adenomyoma. Methods Blood flow parameters and SWV (shear wave velocities) from 42 regular hysteromyomas,14 abnormal hysteromyomas and 25 uterine adenomyomas were compared and analyzed through color Doppler. Results The SWV of regular hysteromyomas was on average of (2.72 ± 0.31) m/s;that of abnormal hysteromyomas (1.88 ± 0.25) m/s;while the SWV of uterine adenomyomas was on average of 1.91 ± 0.27 m/s. The mean SWV in regular hysteromyomas group was significantly higher than that in abnormal hysteromyomas group and uterine adenomyomas group (P < 0.05). There was no significant difference of SWV between abnormal hysteromyomas group and uterine adenomyomas group (P > 0.05).The resistance index and SWV of uterine hysteromyomas and adenomyomas had positive correlation (r = 0.753,0.544,0.506,P < 0.05). Conclusion VTQ can quantify the stiffiness of uterine hysteromyoma and adenomyoma.

The leaves of Scindapsus aureum were frozen at\|19℃ for 5 mins after sprayed with 91?g/mL Ampicillin and 91?g/mL streptomycin sulfate mixture solution,After 15 days the results showed that frozen spot number of the leaves treated with water reduced by 75% compared with those of CK,but thethickness unchanged.The frozen spots began with the border of the leaves.The frozen spots of the group treated with antibiotic mixture solution didn't appear until 5 mins later,and the number of the frozen spots reduced by 95% after 8 mins of freezing.They covered the border of the leaves.This indicated that the antibiotic mixture solulion can obviously reduce the freeze injury to the leaves.

Objective: To investigate the effects of 3'-hydroxy puerarin on improving insulin resistance in 3T3-L1 adipocytes and their mechanisms. Methods: The proliferation of 3T3-L1 preadipocytes was tested by MTT assay and the differentiation by oil red O staining. The insulin resistance model was induced by dexamethasone. Cellular glucose consumption was determined by GOD-POD assay and the concentration of FFA by colorimetric methods. The expression of PPARγ and PTP1B genes in insulin resistant adipocytes was analyzed by qPCR. The PPARγ-transactivation activity of 3'-hydroxy puerarin was examined by using a hybrid reporter gene assay and the activity of PTP1B by colorimetric methods. Results: Compared with the medium control group, 3'-hydroxy puerarin significantly activated PPARγ at 0.1 and 10 μmol/L (P < 0.05, 0.01), but showed no effect on PTP1B (P > 0.05); increased the proliferation and differentiation of 3T3-L1 preadipocytes at 1-10 μmol/L (P < 0.05, 0.01). Compared with model group, 3'-hydroxy puerarin enhanced cellular glucose consumption in insulin resistant adipocytes both in basic and insulin stimulation states, decreased the production of FFA, and up-regulated the expression of PPARγ gene (P < 0.01), but showed no effect on the expression of PPARγ gene (P > 0.05). Conclusion: 3'-Hydroxy puerarin can improve the insulin resistance via up-regulating the expression of PPARγ.

OBJECTIVE: Understand the changes before and after treatment in patients with severe OSAHS serum S100β protein, NSE levels and cognitive function. To investigate the molecular mechanisms of cognitive dysfunction in patients with severe OSAHS. Serum S100β protein, NSE levels and cognitive function were examined before and after the therapy. METHOD: Select one hundred patients diagnosed as severe OSAHS were included, by polysomnography (PSG) diagnosis of severe OSAHS patients. Determination of serum S100β protein, and NSE levels and theat the same time be MoCA score were checked at after the day after admission, CPAP treatment for the 7th days after CPAP treatment and the 90th day after, comprehensive treatment in these patients for 3 months. Assessment of severe OSAHS patients with serum S100β protein, NSE basic level and MoCA score situation. Comparison of three groups serum S100β protein, NSE levels and MoCA score changes. Serum S100β protein, NSE detection assay (ELISA) method using enzyme-linked immunosorbent. RESULT: (1) Severe OSAHS patients with serum S100β protein, and NSE levels in severe OSAHS patients were positively correlated with AHI, but negatively correlated with lowest oxygen saturation (LSaO2); (2) MoCA score in patients with severe OSAHS was significantly negatively correlated with AHI, but positively correlated with LSaO2; (3) S100β protein, NSE levels were negatively correlated with MoCA score; (4) Compared with admission, serum S100β protein, and NSE levels in these patients have declined after 7 days CPAP therapy, compared with admission the difference was statistically significant (P < 0.05). After 3 months of comprehensive treatment, patients' serum S100β protein and, NSE levels were significantly decreased, compared with the admission and the 7th days after CPAP treatment. The difference was statistically significant (P < 0.05). (5) After CPAP treatment for 7 days, the MoCA scores were slightly higher, but have there was no statistically significant difference compared with the admission (P > 0.05). After 3 months of comprehensive treatment, MoCA score improved significantly, compared with the admission and 7 days after CPAP treatment the difference was statistically significant (P < 0.05). CONCLUSION Comprehensive treatment can reduce serum S100β protein, and NSE levels, and improve MoCA score. Disease severity in patients with OSAHS have a correlation some relative.with the serum S100β protein, NSE levels and MoCA score. Long-term hypoxemia and the structure of sleep disorders may be the cause of elevated serum S100β protein, NSE levels elevated and causes of cognitive dysfunction. Comprehensive treatment can improve patient hypoxemia, correct disorders of sleep structure ,and can improve cognitive function and to improve the quality of life of patients.

Objective To observe apoptotic cells and caspase-3-positive cells in ipsilateral neonatal hypoxic-isch?emia encephalopathy (NHIE) model in mice. Methods CD1 mice of age 7 days (n=30) were randomly divided into two groups: sham group (n=9) and model group (n=21). NHIE model was induced by right common carotid artery ligation fol?lowed by 8%oxygen hypoxia for 100 min. TTC staining was used to determine area of brain infarction. DAPI staining was used to detect pathological change in brains. TUNEL assay was used to detect apoptotic cells and fluorescence immunohisto?chemistry was used to detect caspase-3 expression in the ipsilateral brain. Results No infarct was detected in sham group. Cells were densely and orderly arranged in brain. TUNEL-positive cells (18.57±4.98) and caspase-3-positive cells (9.17± 2.14) in the ipsilateral brain were both less than those in the ipsilateral brain of mice in model group (209.57±41.27) and (63.33±16.22) respectively. Mice in model group presented infarct in the right hemisphere with more dead cells and wider in?terstitial space compared with sham group. Conclusion Brain injury in NHIE model might be related to the increasing cas?pase-3 expression thus leads to apoptosis.

Objective To investigate the correlation between 28-day prognosis and red cell distribution width (RDW) in sepsis patients.Methods This was a prospective observational study.Two hundred and thirteen sepsis patients were consecutively selected,and the patients were divided into 2 groups according to RDW:normal RDW group (RDW ＜ 0.15,160 cases) and high RDW group (RDW≥0.15,53 cases).The general conditions,acute physiology and chronic health evaluation (APACHE) 1Ⅱ score,sequential organ failure assessment (SOFA),hypersensitive C reactive protein (hs-CRP),procalcitonin (PCT),arterial blood lactic acid,liver function injury,renal function injury and 28-day mortality were compared between 2 groups.The independent risk factors of 28-day prognosis were analyzed by multifactor Logistic regression analysis.Kaplan-Meier survival analysis was used to draw the 28-day survival curve,and the survival rate was compared between 2 groups by log-rank test.Results The 28-day mortality in high RDW group (35.8％,19/53) was significantly higher than that in normal RDW group (17.5％,28/160),and there was statistical difference (P =0.007).RDW ≥0.15 was the independent risk factor of 28-day death in sepsis patients (OR =2.634,95％ CI 1.316-5.273,P =0.006).After adjusted by gender,age and other relative factors,RDW≥0.15 was the independent risk factor of 28-day death in sepsis patients (OR =2.895,95％ CI 1.155-7.252,P =0.023).The 28-day accumulative survival rate in high RDW group was significantly lower than that in normal RDW group (50.5％ vs.63.0％),and there was statistical difference (P =0.014).Conclusion The high RDW in sepsis patients is the independent risk factor of 28-day death,and RDW ≥0.15 shows an important predictive value in the prognosis of sepsis patients.
