Objective To investigate the diagnosis and therapy of vaginal intraepithelial neoplasia (VAIN) and correlation to cervical intraepithelial neoplasia (CIN). Methods The clinical and pathological data about age, liquid-based cytology, human papillomavirus (HPV) DNA test, colposcopy,histology types and treatment in 35 patients with VAIN were reviewed to investigate the diagnosis and therapy of VAIN and correlation to CIN. Results Mean age at presentation was 43.9 years. The percentage of VAIN I, VAINⅡ and VAINⅢ were 52% (18/35), 34% (12/35) and 14% (5/35), respectively. 8% (1/13) of patients were younger than 40 years developed VAIN Ⅲ, while 18% (4/22) patients were eider than 40 years. There were 83% (29/35) cases were diagnosed from 2007 to June 2008. 69% (24/35) or 17% (6/35) cases had the history of CIN or cervical cancer, respectively. VAIN Ⅱ - Ⅲ accounted for 3/9, 53% (8/15) and 4/6 of CIN I , CIN Ⅱ - Ⅲ and cervical cancer, respectively. There were 87% (13/15) positive high risk HPV infection in VAIN Ⅰ , while 100% in VAIN Ⅱ and VAINⅢ. There were 97% (33/34) cases with abnormality for liquid-based cytology and 86% (30/35) cases of lesions were located in the upper 1/3 vagina. Among 19 cases received therapy, 14 eases (74%) were treated by surgery, 2 eases (11%) by brachytherapy, 3 cases (16%) used drug on the surface of vagina and the lesions were shown recovery in 9 cases followed up. Conclusion The clinical characteristics of VAIN are similar to CIN and the principles of diagnosis and treatment are also the same as that of CIN.

Through retrieval of all medical journals of CNKI and VIP from Jan. 1996 to Oct. 2012, ninety-nine articles were selected and analyzed. The result shows that reliable effect can be found in pain relieving, especially in pain of muscles and soft tissues. In mechanism research, action mechanism of Fu's subcutaneous needling (FSN) on pain relieving is expounded through theory of traditional medicine and modern medicine. Although the effect of FSN on pain relieving has been confirmed by numerous clinical trials, it is still lack of explanation on mechanism revealing. The further studies should focus on mechanism expounding, improving research methods and selecting more objective and reasonable evaluation system. Therefore, the effectiveness and scientificalness of FSN can be further enhanced.

Objective To assess the effectiveness of the clinical pathway for the treatment of advanced schistosomiasis he-patic fibrosis. Methods The duration of hospital stay,gross hospitalization expense,individual-paid expense,interior diame-ter of portal vein,levels of four serum hepatic fibrosis-related parameters(PIIIP,CIV,HA,and LN),and activities of ALT, AST andγ-GT were assessed and compared between the advanced schistosomiasis patients receiving the clinical pathway and ones receiving non-clinical pathway. Results There were 142 advanced schistosomiasis patients with hepatic fibrosis receiving the clinical pathway of anti-hepatic fibrosis. Compared with the patients receiving non-clinical pathway ,the gross hospitalization expenses reduced by 11.2%(t=6.310,P<0.05),and the individual-paid expenses reduced by 16.1%(t=4.326,P<0.05). The mean HA level was twice higher than the normal range,with a positive rising from 70.4%to 83.1%,and the abnormal rates of CIV andγ-GT were 64.1%and 28.9%respectively. Conclusions The clinical pathway can drastically reduce the treatment expenses in advanced schistosomiasis patients with hepatic fibrosis. However,the patients have a trend towards the persistent disease progression. Therefore,the researches of more effective therapeutic methods for advanced schistosomiasis hepatic fibro-sis are urgently needed.

[Objective]To investigate the effect of pantoprazole on skeletal muscle wasting in cancer cachexia and the possible mechanism.[Methods]24 male BALB/c mice were randomly divided into control group(NN),cancer cachexia group(CC),pantrop?razole treatment group(PPI). The mice in CC and PPI were inoculated subcutaneously with mouse colon adenocarcinoma C26 cells to establish a model of cancer cachexia. The mice in PPI group were gavaged with 75 mg/kg pantoprazole dissolving in physiological saline,while those in NN and CC group were gavaged with 0.1 mL/10 g physiological saline. The mice were killed 12d after treatment. The weight of gastrocnemius and tumour and the size of tumour were measured. The morphological change of skeletal muscle were evalu?ated by the method of stain with hematoxylin and eosin(H&E). The levels of IL-6 and TNF-αin serum were tested by ELISA. qRT-PCR was used to assess the expression of mRNA of Myod1 and myf5 in skeletal muscle. The protein expressions of MuRF1,MAFBx, Myod1 and myf5 were measured by Western blot.[Results]Compared with CC group ,pantoprazole can increase the weight of mice and gastrocnemius(39.8% and 24.2%,respectively),cross section area(25.4%),levels of mRNA and protein of Myod1 and myf5(P<0.05),while the levels of IL-6 and TNF-αdecreased(30.7%and 18.9%,respectively),as well as the levels of protein ex?pression of MuRF1 and MAFBx(P < 0.05).[Conclusion]Pantoprazole can attenuate the wasting of skeletal muscle,the potential mechanism may be related to the inhibition of inflammatory factors and UPS ,and up-regulation of Myod1 and myf5.

OBJECTIVE:
To access application value of multi-slice spiral computed tomography (MSCT) and coronary artery calcium scoring (CACS) in investigation the coronary artery disease (CAD), and to explore the effective way of virtual autopsy to evaluate the sudden death due to CAD.
METHODS:
Nine cases of sudden cardiac death were collected to analyze MSCT before the autopsy. The quantitative analysis of the degree of coronary artery calcium was made by Agatston's method. The CACS of all the subjects were calculated based on the diagnostic criteria for CAD, in which calcium scoring was more than 400. The results of CACS were compared with that of the autopsy.
RESULTS:
Only 2 cases got the high calcium scoring which were more than 400 in the 9 cases died of CAD confirmed by the autopsy. The prediction rate of CACS for CAD was only 22.2%. Pulmonary edema of different severity was found in both autopsy and MSCT. There was a higher morbidity rate in the left anterior descending of coronary artery than the other branches.
CONCLUSION
Obvious calcification of coronary artery can be detected by MSCT and calculating CACS. To detect subtle calcification needs other technologies such as postmortem angiography.

OBJECTIVETo explore the role of CXCR4/SDF-1alpha axis in organ-specific metastasis of nasopharyngeal carcinoma (NPC) by assessment of CXCR4 expression in NPC cells and SDF-1alpha expression in distant target organs of NPC.
METHODSThirty patients with NPC and fifteen normal subjects were recruited in this study. The expressions of CXCR4 in NPC and normal cases were identified by RT-PCR and immunohistochemistry (IHC), then the relationship between CXCR4 expression and clinicopathological factors was analyzed. IHC was also used to analyze the SDF-1alpha protein expression in normal cervical lymph nodes (including normal superior and inferior deep cervical lymph nodes), bone marrow, lung, liver, kidney and colon tissues of NPC patients (5 cases/each group).
RESULTSThe relative expression level of CXCR4 mRNA in NPC (0.71 +/- 0.22) was significantly higher than that of normal nasopharynx tissues (0.14 +/- 0.07, F = 27.94, P < 0.05). The relative expression level of CXCR4 protein in NPC (1.58 +/- 0.59) was significantly higher than that of normal nasopharynx tissues (0.51 +/- 0.22, F = 17.75, P < 0.05). The high expression levels of CXCR4 mRNA and protein in NPC were closely related to clinical stage, cervical lymph node metastasis and cancer cell differentiation (P < 0.05). SDF-1alpha protein was strongly expressed in normal superior deep cervical lymph nodes, bone marrow, lung and liver (2.35 +/- 0.67), but absent or very poor expression in inferior deep cervical lymph nodes, kidney and colon tissues (0.68 +/- 0.23), and the differences between them were statistically significant (t = 10.13, P < 0.01).
CONCLUSIONCXCR4 is closely correlated to metastasis of nasopharyngeal carcinoma. CXCR4/SDF-1alpha axis may play an important role in organ-specific metastasis of NPC.
