A wide range of uncomfortable symptoms are attributed to menopause.It is also during this time that women are at increasing risk of poor medical conditions such as osteoporosis,cancers and dementia.Most physicians pay attention to the proper selection of effective and reasonable therapeutic methods,unfortunately,no agreement exists on the clinical recommendations and choice.The article reviewed hormone replacement therapy(HRT),common therapy and traditional medical therapy.

Objective:To investigate the effect of short-term intensive treatment with insulin on metabolic control,?-cell function and insulin resistance in newly diagnosed type 2 diabetic patients. Methods:Thirty-eight newly diagnosed type 2 diabetic patients were randomly divided into two groups and treated with continuous subcutaneous insulin infusion(CSII) or multiple daily insulin injection(MDI) for 1 month.Fasting blood glucose(FBG) and lipid profiles were measured,and oral glucose tolerance test(OGTT)was performed before and after the treatment.The second phase insulin and C peptide secretions were measured by calculating area under curve(AUC) in OGTT.HOMA model was used to evaluate ?-cell function((HOMA-?)) and insulin resistance. Results:Excellent control of FBG was achieved after 1 month intensive treatment.(HOMA-?) was improved significantly. Conclusion:The excellent metabolic control and ?-cell function improvement can be achieved by short-term intensive insulin therapies like CSII or MDI.

Objective To evaluate the effectiveness of treating glioma in combination with drugs multiply by comparing the size of tumor and the survival time of different groups in rat glioma after targeted blood-brain barrier (BBB ) disruption by MRI-guided focused ultrasound.Methods The stereotaxis instruments and the 10 μl gas-tight syringes were used to inject gliosarcoma cells into the targeted area of the brain in 50 male Sprague-Dawley rats.The glioma-bearing rat model was established.Each rat received either:(1 )no treatment (control;n =8);(2)single liposomal doxorubicin (DOX;n = 10);(3)multiple DOX (n =10);(4)single Avastin (AVS)and DOX (n =10);(5)multiple AVS and DOX (n =10).The SonoVue microbubble ultrasonic contrast agent and DOX or AVS were injected into the tail vein respectively on day 12 after implantation.The tumor size was measured by MRI on pre-treatment,immediacy and once a week of post-treatment after targeted BBB disruption by focused ultrasound,and the life span in rat glioma was recorded.Results The mediam survival of different groups in rat glioma(The range of the life span 13-90 d):no treatment (7 d);single DOX (12 d);multiple DOX (1 5 d);single AVS + DOX (22 d), multiple AVS+ DOX (30 d).There was significant difference of the groups on mediam survival comparison (P < 0.01 ).The tumor growth pattern after post-treatment of different groups in rat glioma except control:single DOX was noticeable fast and multiple AVS+DOX was visibly delayed comparable to other groups,and finally the tumor size of multiple AVS + DOX even became small.Conclusions The microbubble blasting enhances the local tissue permeability and promotes the drug delivery of chemotherapy and anti-angiogenesis locally in glioma-bearing rats by MRI-guided focused ultrasound.Especially,the combination with drugs multiply has a synergism efficacy that may enhance the effectiveness of chemotherapy,reduce tumor growth,and even become small of the tumor size,and increase survival time significantly after BBB disruption.

Cardiovascular disease is a serious threat to human health and quality of life ,and it has become the leading cause of death in human.Thus,looking for effective drugs to reduce the mortality and morbidity of such a disease has become a problem to be solved.Due to its good efficacy of activating blood circula-tion and dissipating blood stasis,salvia miltiorrhiza has been widely used in the treatment of cardiovascular disease and ob-tained a good curative effect.Salvianolic acid B is one of the main water-soluble components of salvia miltiorrhiza extract and studies have shown that salvianolic acid B possesses many biolog-ical activities,which not only has a good protective effect on my-ocardial infarction,but could significantly alleviate myocardial ischemia-reperfusion injury.This article reviews the research progress of salvianolic acid B in cardiovascular diseases,and al-so includes discussion about the mechanisms of salvianolic acid B in the regulation of cardiovascular diseases,which may provide references for follow-up research and clinical treatment.

ObjectiveTo establish a method for measuring exhaled nitric oxide (eNO)concentrations in neonates with and without hypoxemic respiratory failure ( HRF), and to investigate the relationship between eNO and respiratory parameters in neonates with HRF. Methods Twenty-two newborn infants with HRF and 26 control neonates were included within the first 24 hours of postnatal life.Their eNO levels were detected with a rapid-response chemiluminescence analyzer daily during the first week of their postnatal life, and lung mechanics and gas exchange efficiency were monitored at the same time, such as pulse oxygen saturation ( SpO2 ), inspired fraction of oxygen ( FiO2 ) and other parameters.Wilcoxon Mann-Whitney U tests were used to compare eNO, SpO2/FiO2 and eNO/ ( SpO2/FiO2 × 100) in two groups. Pearson's correlation analyses were used to determine the relationships between eNO levels and indices of hypoxemic respiratory failure. ResultsDuring the first two days of postnatal life, eNO values of HRF neonates were higher than those of the control neonates[day 1,(7. 9 ± 3.2 )× 10-9 vs. (5.8 ±1.8)×10-9, P＜0.05;day2, (8.8±3.2)×10-9vs. (6.0±2.4)×10-9, P＜0. 05], butthere were no significant differences in the following days. With SpO2/FiO2 increasing, difference of eNO values between the HRF and non-HRF controls became narrowed, but there was still two fold difference of eNO/(SpO2/FiO2 × 100) on day 5-7. ConclusionsA method for measuring eNO was established and there was difference in neonates with and without HRF, which diminished with prolonged postnatal days, reflecting pathophysiological characteristics of HRF.

Objective To evaluate the significance of COLD-PCR in detecting KRAS mutation of pancreatic cancer and colorectal cancer patients. Methods First, set up COLD-PCR and compared the sensitivities of COLD-PCR/Sanger sequencing with PCR/Sanger sequencing using mixed cell lines ( KRAS wild-type cell line SW116 and KRAS mutant cell line SW480).Then, detected KRAS mutation of 20 formalin-fixed paraffin-embedded samples of pancreatic cancer and 39 formalin-fixed paraffin-embedded samples of colorectal cancer using PCR/Sanger sequencing and COLD-PCR/Sanger sequencing, respectively and compared the coincidence rate and consistency. Results The low detection limits of PCR/Sanger respectively. KRAS frequency detected by COLD-PCR/Sanger sequencing [75% (15/20)] in 20 cases of pancreatic cancer was higher than that detected by regular PCR/Sanger sequencing [40% ( 8/20 ) ,x2 =5.013, P < 0.05]. KRAS frequency detected by COLD-PCR/Sanger sequencing [44% (17/39)] in 39 cases of colorectal cancer was higher than that detected by regular PCR/Sanger sequencing [31% (12/39) ,x2 =1. 372, P = 0. 174]. The coincidence rate of these two methods was 0. 730 and the difference had no statistical significance. The coincidence rate of detecting KRAS mutation was 65% in pancreatic cancer and the results showed a good correlation between two methods and the two methods had bad agreement in diagnosis (Kappa = 0. 364, P < 0. 05 ). COLD-PCR/Sanger sequencing could detect more cases of KRAS mutations from pancreatic caner than regular PCR/Sanger sequencing. This was because there were many non-tumor cells in pancreatic tumor tissue and COLD-PCR/Sanger sequencing was more sensitive than regular PCR/Sanger sequencing. The coincidence rate of detecting KRAS mutations was 87% in colorectal cancer and the results were showed a good correlation between two methods and the two methods had substantical agreement in diagonsis ( Kappa = 0. 730, P < 0. 05 ) . Conclusion COLD-PCR/Sanger sequencing is highly sensitive to screen KRAS mutation in pancreatic cancer and colorectal cancer patients.

Objective To investigate the clinical pathologic significance of lymphangiogenesis in in colorectal cancer. Methods New lymphatic-specific markers D2-40 was used immunohistochemically to detect the lymphatic vessel density(LVD) in the intratumoural and peritumoral areas, and in normal tissue from 96 cases of colorectal cancer, which were analyzed with clinical pathologic parameters of those colorectal cancer. Results Significandy higher LVD was found in the intratumoural area(14.5±2.4), when compared with normal(5.9±1.1)and peritumoural areas(6.7±1.2) (P<0.01). LVD of the peritumoural area was higher than normal area (P< 0.01). However, peritumoural LVD was associated with both depth of invasion and liver metastasis (r=0.71,0.78 P<0.05), but not associated with tumour size, macroscopic type and lymph-node metastasis (P>0.05). Intratu-moural LVD was not correlated with tumour size, macroscopic type, the depth of invasion,lymph-node metastasis, and liver metastasis(P>0.05). Conclusion Lymphangiogenesis in the peritumoural area may be helpful in evalution of liver metastasis and prognosis.

Objective To study the protein expressions of Fas-associated death domain protein (FADD) and caspase-8 in rats with intracerebral hemorrhage ,and the effects of erythropoietin tp reveal the mechanism of neu-m-protection by EPO. Methods 126 male SD rats were randomly divided into three groups: Sham-operated group, intracerebral hemorrhage group, and EPO group. Each group was divided into seven subgroups according to the differ-ent time points (3,6,12,24,48,72 h and 7 d). The model of intracerebral hemorrage was established in rats by in-tracerebral injection of autogenous blood. The protein expressions of FADD and caspas-8 in rats tissue around the hemorrhagic and the normal brain tissue were detected by immunohistochemistry. Results The protein expressions of FADD and caspase-8 were increased [(4.66±0.46 ) and ( 15.89±1.81)] at 3 h after intracerebral hemorrhage, and peaked at 48 h [ (35.88±4.24 ) and (45.04±3.99)], the expressions of FADD and caspas-8 in the region around hematoma in EPO group significantly decreased compared with model group[ (3.92±0.64) and (28.24±1.90), (13.32±2.01 ) and (35.08±2.82)] at 3 h and 48 h. Conclusion The protein expressions of FADD and easpase-8 are markedly increased after intracerebral hemorrhage. EPO can protect the neurons by signifi-cantly reducing the expressions of FADD and caspase-8.

Purpose To investigate the value of arterial spin labeling (ASL) in evaluating renal function in patients with renal cell carcinoma (RCC) after laparoscopic partial nephrectomy.Materials and Methods Fifteen patients with RCC undergoing laparoscopic partial nephrectomy were studied prospectively.The patients were performed ASL scan one week before and three months after operation.The correlation between renal blood flow (RBF) value measured by ASL and the glomerular filtration rate (GFR) measured by radionuclide method in the renal cortex of healthy side was analyzed.The RBF values in the kidney of affected side or healthy side were measured,the difference of which between before operation and three months after operation was compared.Results The RBF value and GFR data in the renal cortex of healthy side had positive correlation (r=0.638,P＜0.05).In the affected side of kidney,the RBF value of remaining renal tissue [(291.5 ± 37.3) ml/(100g·min)] compared with that of preoperative renal tissue [(237.8 ± 46.2) ml/(100g·min)]increased about 53.7 ml/(100g · min) (P＜0.05).In the healthy side of kidney,the RBF value of renal tissue [(241.1 ± 50.3) ml/(100 g · min)] compared with that of preoperative renal tissue [(290.4 ± 51.8) ml/(100 g·min)] decreased about 49.3 ml/(100 g·min) (P＜0.05).Conclusion ASL can be used to evaluate renal function,and it is valuable to evaluate renal perfusion function after laparoscopic partial nephrectomy of RCC.

Objective To explore the clinical value of renal dynamic imaging and urinary N-acetyl-?-D-glucosaminidase(NAG),apoptosis DNA fragment(ADF) in evaluating the damage degree of hydronephrotic kidneys(HnK) in children with hydronephrosis.Methods Level of glomerular filtration rate(GFR) was detected in 41 children with congenital hydronephrosis by renal dynamic imaging,and urine NAG,ADF in pelvis in HnK and healthy kidneys (as controls) were detected by enzyme-linked immuno-sorbent assay(ELISA).Patholo-gic changes of HnK in 41 children were graded intoⅠ~Ⅴ according to Elder standard. And GFR,urinary NAG and ADF of HnK were divi-ded into subgroup according to pathologic changes ,at the same time statistical analysis was performed within each groups. And the correlations of pathologic grades with GFR,urinary NAG and ADF of HnK were analyzed.Results 1.Kindneys GFR in healthy kidneys and Hnk were (174.33?20.43)?10-3 L/min,(143.86?17.51)?10-3 L/min respectinely,and there was significant difference between healthy kidneys and Hnk (P0.05).3.There was significant negative correlation between GFR levels of HnK and pathologic grades(r=-0.814 P0.05).Conclusions For hydronephrotic kidneys,urinary NAG can eva-luate impaired nephric tubule whereas renal dynamic imaging may evaluate the damage level of glomeruli;urine ADF may not indicate the damage level of diseased kidneys in children with congenital hydronephrosis.
