Objective To investigate the relationship between the expression of regulated-upon activation normal T expressed and secreted(RANTES)and microvascular density(MVD)in hepatocarcinoma(PHC)tissues,and explore its clinical significance. Methods The samples of PHC tissues and adjacent tissues in 47 patients were collected.The expression of RANTES in tissues was detected by immunohistochemistry,and MVD was calculated.The relationship among the expression of RANTES,MVD and clinicopathological features was analysed. Results The positive expression rate and expression score of RANTES in PHC tissues were significantly higher than those in adjacent tissues(55.32% vs 19.15%,P<0.01;1.89±1.77 vs 0.77±1.29,P<0.01).MVD in PHC tissues was significantly higher than that in adjacent tissues(67.30±13.68 vs 37.20±10.58,P<0.01).MVD of PHC tissues in patients with metastasis was significantly higher than that in patients without metastasis[(73.50±13.77)/HP vs (64.10±12.68)/HP,P<0.05],while there were no correlations among MVD,expression of RANTES and the other clinicopathological features of PHC.MVD was positively correlated with the expression score of RANTES in PHC tissues(r=0.386,P<0.05). Conclusion RANTES might be closely related to the angiogenesis in PHC.

Objective To explore the difference between the stapes prosthesis surgery with microscope and with otoscope. Methods Fifty-four patients with otoselerosis accepted stapes prosthesis surgery with the same kind of stapes prosthesis, done in the same operative method by the identical surgeon.All the operations were done with microscopes or with otoscopes. The operative difference and therapeutic effects between microscope surgery and otoscope surgery were analysed. Results There was no difference in the postoperative heating improvement between microscope surgery and otoscope surgery; the operative time of microscope surgery [(30±7)] min was much shorter than that of otoscope surgery [(60±5)] min,with significant statistical difference. Conclusions Stapes prosthesis surgery with microscope, which has advantages of bimanualness, easiness, and short operative time, is much better than that with otoscope.Thus, microscope is still the preferred magnifying equipment in stapes prosthesis surgery.

Objective: The Phenomenon of different species with the same name has created potential threats to cinical safety of medication. Because of that, two kinds of “gonglao leaf” and their sibling adulterants have been identified by molecular methods in this study, to secure its safety in medication. Methods: Ilexcornuta, Mahoniabealei, Mahoniafortuneiand their sibling adulterants total of 9 species 45 samples were collected in this experiment,Total genomic DNA was extracted from them by the method of improved CTAB, ITS2 sequences were amplified, and the PCR products were sequenced. Sequence assembly and consensus sequence generation were performed by the CodonCode Aligner V 4.2.4.. The genetic distances were computed by MEGA 6.0 in accordance with the Kimura 2-Parameter (K2P) model and the phylogenetic tree constructed by the neighbor-joining (NJ) method. Results: The analysis results of the genetic distances, variable sites and the NJ phylogenetic tree showed that Ilexcornuta, Mahoniabealei, Mahoniafortunei were seperated from their sibling adulterants obviously. Conclusion: ITS2 sequence was able to identify two kinds of “gonglao leaf” and their sibling adulterants which can provide a basis for clinical accurate medication.

Objective: To explore the relationship among somatostatin (SS), neuron-specific enolase (NSE) and early vascular dementia.Methods: A total of 40 patients with early vascular dementia treated in our hospital were selected as vascular dementia group, another 40 inpatients with cerebral infarction (CI) treated during the same period were enrolled as CI group.Plasma NSE and SS levels were compared between two groups during different periods.Results: Compared with CI group at onset, one month and three months after CI, there was significant rise in plasma NSE level[(22.08±7.05) ng/ml vs.(26.39±6.80) ng/ml, (23.92±4.25) ng/ml vs.(28.12±4.06) ng/ml, (25.55±4.72) ng/ml vs.(30.10±4.33) ng/ml], and significant reduction in plasma SS level[(1084.50±133.00) ng/ml vs.(748.30±129.10) ng/ml, (836.40±160.20) ng/ml vs.(624.25±140.50) ng/ml, (690.25±146.30) ng/ml vs.(432.70±151.00) ng/ml]in vascular dementia group, P<0.05 or <0.01.Plasma NSE level gradually rose and SS level gradually reduced along with the time went by(P<0.05 or <0.01).Conclusion: Early dynamic detection of somatostatin and neuron-specific enolase levels in patients with cerebral infarction may help to early diagnosing and treatment of vascular dementia.

BACKGROUND: Breast augmentation with polyacrylamide hydrogel injection has been used nearly for a decade in some Chinese medical therapy units. More patients need to be removing injections or a second augmentation due to complications. More attention should be paid for possibility of complications concomitant with breast malignant tumor. OBJECTIVE: Two cases of breast invasive duct carcinoma diagnosed after removing injection were analyzed retrospectively in order to increase the importance of detection rate of breast malignant tumor. METHODS: Two cases in all 41 assembled patients which were removed polyacrylamide hydrogel injections from 82 breasts were diagnosed with invasive carcinoma. The characteristics of medical history, physical diagnosis, image diagnosis and pathological examination were analyzed retrospectively. RESULTS AND CONCLUSION: The detection rate of breast malignant tumor should arise more attention in patients requiring removal of polyacrylamide hydrogel injection. The following aspects should be emphasized such as the comprehensive analysis for the results of physical diagnosis and image diagnosis, tumor-free operation with more samples from suspicious nodules and frozen pathological examination. The principles of cancer surgery should be followed in pathological diagnosed cases in case of iatrogenic metastasis and spread of breast malignant tumor.
