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.

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.

Currently,there is a worldwide increase in the incidence and mortality of intrahepatic cholangiocarcinoma (ICC),but the etiology of ICC remains unclear.Recent efforts suggest an etiological role of hepatitis B virus (HBV)infection in ICC,and this article reviews the relationship between chronic HBV infection and the risk and prognosis of ICC.

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 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.

BACKGROUND: Root canal files fracture is a kind of common oral clinical complications. Therefore, it is of clinical importance to study the cyclic fatigue of different types of stainless steel root canal files.OBJECTIVE: To explore the effect of the bending angle and cross-sectional area of root canal instruments on cyclic fatigue of stainless steel files.METHODS: Thirty 25# stainless steel K files (25 mm in length) were selected, the same to 30# and 35#. And these three kinds of files were respectively randomized into three groups (n=10 per subgroup). In the nine subgroups, the files were placed into self-made root canals at the bending angle of 45°, 60°, 90°, and driven by a 16:1 reducer (350 r/min).Fracture time in each subgroup was recorded and converted into the number of rotations. The microstructure of the fracture end of the files was observed under scanning electron microscope. Fractured files were collected and the crack tip length was measured by an electronic caliper.RESULTS AND CONCLUSION: At the same bending angle, the number of rotations resulting in file fracture was significantly reduced with the increasing of the cross-sectional area of the files (P < 0.05). When the type and cross-sectional area were same, the number of rotations resulting in file fracture was significantly reduced with the increasing of the bending angle of the root canals (P < 0.05), indicating a reduction in the cyclic fatigue performance of the files. Toughness fracture occurred in all the files, and circular or oval roughness nests with different sizes and microcavities formed on the fracture surface. In addition, brittle surfaces could be detective between the roughness nests. The diameter of roughness nests was gradually increased with the increasing of the bending angle of the root canals. For 30# and 35# files, the number of brittle surfaces was gradually increased with the increasing of the bending angle of the root canals. For 25# files, the crack tip length was gradually decreased with the increasing of the bending angle of the root canals, but there was no significant difference (P > 0.05). For 30# and 35# files, the crack tip length was significantly shortened with the increasing of the bending angle of the root canals (P < 0.05). But there were no significant changes in the 35#-60° and 35#-90° groups (P=0.095). At the same bending angle, there were no regular changes in the crack tip length in the different types of files. In conclusion, with the increasing of the cross-sectional area, the cyclic fatigue performance of the files with the same length and taper is reduced and the files become easy to be fractured; with the increasing of the bending angle of the root canals, the files with the same types are apt to be fractured near the root tip, indicating the shorter length of the crack tip indicates the more difficulty in the removal of the broken files.
