The current treatments of metastatic malignant melanoma include chemotherapy,targeted therapy,immune therapy and radiation therapy,but the treatment outcome is far from optimism.In order to im-prove the treatment efficiency,it is urgent to improve early diagnosis,and develop more effective treatment drugs and delivery systems.The application of nanotechnology in the diagnosis and therapy of melanoma can re-duce the resistance to the drugs,increase efficacy and reduce side effects.

Intravoxel incoherent motion (IVIM) can distinguish the molecular diffusion from the pseudo-diffusion of microcircular perfusion to obtain true diffusion coefficient (D),pseudo-diffusion coefficient (D*) and perfusion fraction (f),which are sensitive to detect alterations in cellularity and microcirculation perfusion.IVIM can also evaluate early therapeutic effects,optimize treatment plan,predict prognoses,and provide information for choosing appropriate treatment methods.In this paper,the principle of IVIM and its application in tumor response evaluation were reviewed.

Objective To observe the effect of medication compliance and self-efficacy of schizophrenia patients with diabetes by continuing self-management education. Methods A total of 60 patients with schizophrenia with diabetes diagnostic criteria were divided into experimental group (30 cases) and control group (30 cases) by the admission number, 2 groups received conventional drug treatment, the control group received general preaching health education pattern, were each issued a health education manual, with schizophrenia and diabetes health knowledge division, the test group on the basis of the continuation of the implementation of self-management education, followed up 12 months after discharge, compared 2 groups of patients with medication compliance and recurrence rate, with General Perceived Self-Efficacy Scale (GSES) assessment level of 2 groups of patients with self-efficacy, fasting blood glucose (FPG) was determined by automatic biochemical analyzer, 2 hours postprandial blood glucose (2 hPBG). Results Six months after discharge, 82.1%(23/28) cases were complete compliance, 14.3%(4/28) cases of partial compliance, 3.6%(1/28) cases of non-compliance, 55.2%(16/29)cases of the control group complete compliance, 27.6%(8/29) cases of partial compliance, 17.2%(5/29) cases of non-compliance, the differences between two groups were statistically significant (χ2=37.41, P<0.05). The 12 month test group of full compliance discharged 75.0%(21/28) cases, 14.3%(4/28) cases of partial compliance, 10.7%(3/28) cases of non-compliance, 31.0%(9/29) cases of the control group complete compliance, 31.0%(9/29) cases of partial compliance, 37.9%(11/29) cases of non-compliance, the test group compliance was higher than the control group (χ2=11.27, P<0.05). The score after 6 months and 12 months respectively for the test group general self-efficacy scored 35.32 ± 2.02, 34.18 ± 1.77, control group scored 24.03 ± 3.04, 22.48 ± 2.01, the differences between two groups were statistically significant (t=16.445, 23.304, P<0.01). After 6 months in test group FPG and 2 hPBG were (5.71 ± 1.05), (9.46 ± 1.37) mmol/L, control group were (7.79 ± 1.05),(12.28 ± 2.07) mmol/L, the differences between two groups were statistically significant (t=7.483, 6.023, P<0.01). 12 months after discharge in test group FPG and 2 hPBG respectively (5.89±1.13), (9.68±1.09) mmol/L, control group (9.14±1.19), (13.17±1.42) mmol/L, test group FPG and 2 hPBG were lower than the control group (t=10.550, 7.431, P<0.01). After 6 months and 12 months, the recurrence rate of experimental group were 7.1% (2/28) and 24.1% (7/29) respectively, and control group were 14.3%(4/28) and 44.8%(13/29), the recurrence rate of experimental group was lower than the control group, there was significant difference between 2 groups (χ2=4.326, 6.225, P< 0.05 or 0.01). Conclusions Self-management education can improve the medication compliance and self-efficacy, improve mental symptoms and sugar metabolism, and reduce the recurrence rate.

Objective To analyze and compare two potency assay methods of protamine sulfate.Methods Heparin titration method was according to foreign pharmacopoeia,while biological assay method was according to China pharmacopoeia(2015).Results The absorbance at the end-point was stable at 0.10 mg/mL and 0.15 mg/mL test solutions.The relative standard deviations(RSDs)of potency results were all less than 5%.Three test solutions and volumes of the titrant had a good linear relationship(R2 =1.000).The results of titration method were significantly related to those of biological assay(P=0.013),with similar RSD(P>0.05).However,the potency of titration method were significantly lower than those of biological assay (P=0.045).Conclusion Heparin titration method is good-using,convenient,and need to be applied widely at home.

0.05),but the ratio of testosterone/estradiol was significantly higher in patients than that of the controls(P

The association of serum uric acid ( SUA ) and urine albumin-to-creatinine ratio ( ACR ) in patients with type 2 diabetes mellitus was explored. The ACR abnormal rate was higher in hyperuricemia group( P＜0.01 ). ACR level was positively correlated with SUA( P＜0.01 ). The general linear model showed that SUA was a risk factor in ACR. Patients with hyperuricemia and type 2 diabetes mellitus were apt to have abnormal ACR and develop early renal damage.

Objective To explore the possible correlation between HbA1c level and nutritional status in community.based patients with type 2 diabetes.Methods A totaI of 219 type 2 diabetes patients were assigned into 2 groups:one with HbAIc<6.5%(n:108)and HbA1f≥6.5%(n=111).Metabolic parameters,food components.and nutritional status were compared between 2 groups.Results (1)49.32% of the participants attained HbA1c<6.5%.(2)HbA1c level was positively correlated with fasting plasma glucose,postprandial plasma glucose,and homeostasis assessment for insulin resistance(HOMA-IR)(r were 0.56,0.49,and 0.20,respectively,P<0.05 or P<0.01),but negatively correlated with high-density lipoprotein-cholesterol(HDL-C)(r=0.16,P<0.05).(3)Linear regression analysis showed that energy,carbohydrate,protein,and fat were the independent risk factors of HbA1c(all P<0.05).(4)Patients with HbA1c<6.5%consumed more fruits.The intake of pure energy-providing foods and protein-,fat-,or saturated fatty acid-rich foods were more frequent in patients with HbA1c≥6.5%(P<0.05).(5)The linear regression revealed that HbA1c level were decreased 0.36%(P<0.10)or 0.46%(P<0.01)by intake of more fruits,roughage and beans,and HbA1c levels were also decreased 0.42%(P<0.05)or 0.37%(P<0.10)by intake of less meat or oils.Conclusions In communitybased patients with type 2 diabetes mellitus,the incidence of HbA1c<6.5% remains low,There exists great difference in nutritional status between the groups with high and low HbA1c levels.The impact of diet OB HbA1c level is great.It's necessary to emphasize the importance of diet therapy far better diabetes control.
