TOF-MS has been more and more widely used in clinical and scientific research due to its advantages such as fast and easily operated.Diabetic nephropathy is the most common complications of diabetes.But clinical existing detection meth-ods to some extent have some hysteresis.The applications and developments of TOF-MS coupled with other proteomics technologies provided new ideas and methods for early diagnosis and prognosis of diabetic nephropathy.In this paper,the lat-est research results in nearest years about the application of TOF-MS to diabetic nephropathy will be reviewed.

Objective To investigate the relationship between the Schatzker types and postoperative knee function in tibial plateau fractures .Methods Totally 120 patients with tibial plateau fracture from January 2010 to December 2014 were selected and performed the Schatzker classification according to the X‐ray film ,CT and three dimensional reconstruction .They were divided into 6 groups .The postoperative knee function in each group was followed up and the statistical analysis was conducted .Results The excellent grade distribution of knee function by Kruskal‐Wallis test had statistical difference among 6 groups(P<0 .05) ,in the fur‐ther pairwise comparison ,the significant differences were found between the group 1 and 2 with the group 4 ,5 and 6(P<0 .05) . Conclusion The Schatzker types of tibial plateau fractures is closely correlated with the postoperative knee function .The knee function scores of type Ⅳ ,Ⅴ and Ⅵ are obviously poor .

Objective To investigate the influence of a catastrophic event to the mental health of servicemen,and to observe the effect of mental intervention and drug treatment for them after experiencing a catastrophic flood attack.Methods 57 servicemen survived a catastrophic flood attack were regarded as the disaster group,and 70 others who were not involved in the flood disaster were regarded as the control group.The service men of the two groups were subjected to investigation with Chinese Military Mental Health Scale(CMMHS),and corresponding mental intervention or medication was given to those who had experienced mental disorders.Results The disaster resulted in different degrees of somatic trauma and various mental disorders including instability of emotion,mental depression,grievance,nervous tension,sensation of fear,sleep disorder and apprehensions.The influential factor scores of CMMHS,including compulsive neurosis,anxiety,depression,fear,psychosis,somatization,interpersonal sensitiveness,and total score were much higher in disaster group than that in control group,and that of norm of Chinese servicemen,while the neurasthenia factor score in disaster group showed no significant difference with that in control group and that of normal Chinese servicemen.The main influential factors to changes in mental health of the servicemen were witness of someone washed away by the flood,and participation in identifying corpses.Conclusion The mental health of servicemen who experienced a catastrophic flood disaster was harmed in various degrees,and medication or mental intervention appeared to be of value.

Objective To investigate the changes of 4 histamine receptors (H1R, H2R, H2R and H4 R)in interstitial cystitis on animal experimental models. Methods Thirty female SD rats (250-300 g) were randomly divided into 2 groups as follows: 20 in experimental group and 10 in control group. The experimental group was filled with protamine sulfate+ potassium chloride to create interstitial cystitis model, the control group was sacrificed directly. At the end of the experiment, the bladders of all these SD rats were studied by the immunohistochemistry staining and the value of their mean absorbance (-A) was calculated by IPP4.5 image analysis software. The SPSS 11.5 was used to analyze the differences between the groups. Results Four kinds of histamine receptors mainly expressed in the bladder epithelium. In the experimental group, the (-A) of H1 R was 0. 054±0.031, the of H2R was 0.032±0.021, the (-A) of H3R was 0.047±0.033 and the (-A) of H4R was 0. 149±0. 191,respectively. In the control group, the A of H1R was 0. 017±0. 011, the (-A) of H2R was 0. 018±0. 015, the (-A) of H3R was 0. 014±0. 011, the (-A) of H4R was 0. 060±0.039, respectively. In contrast,the A of H1 R, H2 R and H3R in experimental group was increased significantly(P<0.05); there was no significant change in (-A) of H4R expression(P>0.05). Conclusions H1, H2 and H3 receptors in rat model interstitial cystitis bladder epithelium have increased and it indicates H1 R, H2R and H3R may be related to interstitial cystitis. H3 R may be a new treatment target of interstitial cystitis.

Objective To investigate the effect of Xiexin Decoction(XXD) on the early diabetic nephropathy(DN) of diabetic rats induced by high-fat diet with injection of streptozotocin(STZ).MethodsMale Sprague-Dawley rats were divided into two groups and fed with normal pellet diet(NPD) or high-fat diet(HFD),respectively,for a period of four weeks and then HFD-fed rats were ip injected with STZ.The diabetic rats were divided into three groups: model group,XXD group,and metformin group.After 13-weeks ig administration,fasting blood glucose(FBG),glycated hemoglobin(HbAlc),blood lipids(TG and TC),serum insulin(INS),renal function,kidney index,albumin in urine,and the renal histology and ultrastructure were observed.Results Compared with the model group,XXD reduced the levels of water intake,food consumption,urine volume,HbAlc,insulin resistance index(IRI),creatinine clearance rate(CCr),albumin in urine and blood lipids(P

An HPLC-UV method has been developed for the determination of valibose, miglitol, voglibose and acarbose, the four anti-diabetic drugs. The separation was accomplished successfully by using reversed phase chromatography (Prevail carbohydrate column, 250 mm x 4.6 mm, 5 microm) with a gradient acetonitrile-phosphate buffer solution (pH 8.0) at a wavelength of 210 nm. Furthermore, the method of a high-performance liquid chromatography coupled with ESI-MS in positive ionization mode has been established. These two methods were successfully applied to the assay and qualitative detection of four alpha-glucosidase inhibitors in the potential counterfeit anti-diabetic drugs.

Objective To discuss the expressions and clinicopathologic significances of insulin-like growth factor Ⅱ mRNA binding protein 3 (IMP3)in squamous intraepithelial lesion (SIL)and cervical squa-mous cell carcinoma (CSCC)before and after the therapy of radiation and chemotherapy.Methods The expressions of IMP3 in 80 cases of CSCC,90 cases of SIL (60 cases of HSIL,30 cases of LSIL)and 30 cases of cervicitis were detected by immunobistochemistry.The relations between IMP3 and clinicopathological cha-racteristics of CSCC were analyzed.Results The expression rates of IMP3 in CSCC,HSIL,LSIL and cervici-tis were 86.3%(69 /80),78.3%(47 /60),33.3%(10 /30)and 0(0 /30),and the difference among the four groups was statistically signicant (χ2 =87.01,P <0.01).The positive expression rate of IMP3 declined by radiation or chemotherapy (60.0% vs.85.0%,χ2 =5.79,P =0.013).The expression of IMP3 was related with lymph node metastasis (χ2 =3.97,P =0.046),differentiated degree (χ2 =5.95,P =0.018),clinical stage (χ2 =5.82,P =0.016)and invasion depth (χ2 =5.73,P =0.017).There was nothing to do with age (χ2 =0.11,P =0.745).Conclusion IMP3 expresses excessively in CSCC,and is associated with pathologi-cal grade and invasion progress.Radio-chemotherapy can reduce the expression of IMP3.

Objective To understand the correlation between TCM service utilization and health behavior of community residents.MethodsAself-designed questionnaire about TCM service utilization and health behavior status was used to investigate 200 people from 4 communities on random sampling. The items in the questionnaire were evaluated and analyzed to test the correlation of TCM service utilization and health behavior of community residents.Results The two indexes significantly correlated in 0.01 level (bilateral),r=0.674, bilateralP=0.000.Conclusion The correlation between TCM community service utilization and health behavior status is positive. The higher the level of TCM community services utilization is, the higher the index value of health behavior status will be.
