OBJECTIVETo investigate the clinical value of Paroxetine combined with mid-frequency electrical pulse acupoint stimulation (EPAS) in the treatment of premature ejaculation (PE).

METHODSTotally 69 PE patients were equally assigned to receive oral Paroxetine 20 mg/d, mid-frequency EPAS, or oral Paroxetine 10 mg/d combined with mid-frequency EPAS (P + EPAS) , all for 8 weeks. We obtained the intravaginal ejaculation latency time (IELT) and Chinese Index of Premature Ejaculation (CIPE-5) scores of the patients before and after treatment, and compared adverse reactions among the three groups of patients.

RESULTSOne patient of the Paroxetine group gave up treatment because of abdominal pain and nausea. Compared with the baseline, the patients in the Paroxetine, EPAS, and P + EPAS groups all showed markedly increased IELT ([0.92 ± 0.11] vs [4.07 ± 0.11] min, P < 0.01; [0.92 ± 0.12] VS [2.78 ± 0.17] min P < 0.05; [0.91 ± 0.09] vs [5.31 ± 0.13], P < 0.01) and decreased CIPE-5 scores (12.5 ± 3.0 vs 22.0 ± 2.1, P < 0.01; 12.8 ± 2.9 vs 19.5 ± 1.9, P > 0.05; 13.1 ± 2.8 vs 25.2 ± 2.1, P 0.01), with statistically significant differences between the P + EPAS group and the other two (P < 0.05). The total effectiveness rate was 95.7% in the P + EPAS group, remarkably higher than in the Paroxetine (72.7%, P < 0.05) and the EPAS group (47.8, P < 0.01).

CONCLUSIONOral Paroxetine combined with mid-frequency EPAS has a higher safety and efficacy than either Paroxetine or EPAS alone in the treatment of PE.

OBJECTIVETo explore the effects of the magnetic c-erbB-2 antisense probe of different concentrations on the morphology and expression of SK-Br-3 cancer cells in vitro.

METHODSBreast cancer SK-Br-3 cells were transfected for 24 h by antisense probe at an iron concentration of 5, 10, 25, 50, and 100 mg/L, respectively. The distribution and content of iron particles in SK-Br-3 cells was determined by Prussian blue staining, electron microscopy, and atomic absorption spectrometry. Cell viability was observed by trypan-blue exclusion and CCK-8 test. The protein expression of c-erbB-2 was assessed by the Western blot analysis. The changes of the signal strength were considered by magnetic resonance imaging (MRI).

RESULTSc-erbB-2 antisense probe was uptake by SK-Br-3 cells in a concentration-dependence manner within a certain range (5, 10, and the Medicine Scientific Research Project of Chongqing Health Bureau (062025)25 mg/L). When the probe concentration was 25 mg/L, iron content in cells was (18.38±0.28) pg, the cell vitality, survival, and c-erbB-2 protein expression were reduced significantly (all P<0.05), and the T2 value was lower significantly (P<0.05). However, the results of 50 mg/L or 100 mg/L group showed no significant difference with the 25 mg/L group (P>0.05).

CONCLUSIONThe magnetic c-erbB-2 antisense probe can effectively transfect and specifically inhibit the expression of SK-Br-3 cell lines at the iron concentration of 25 mg/L.

OBJECTIVETo observe the improvement effects of puerarin on glycated brain damages in rat model induced by D-galactose.

METHODThe model rats of protein glycation were induced by intraperitoneal administration of D-galactose (150 mg x kg(-1) x d(-1)) for 8 weeks, and all rats were treated with puerarin (high dose 300 mg x kg(-1), middle dose 150 mg x kg(-1), low dose 75 mg x kg(-1)) for 6 weeks. The activity of aldose reductase in red blood cells, the amount of glycated products (fructosamine in serum, glycohaemoglobin, advanced glycation end-products) and AGEs in brain tissue, calcium ion in brain cells were measured. Moreover, mitochondria in brain hippocampus cells were observed under electronic microscope.

RESULTHigh dose and middle dose of puerarin can decrease the activity of aldose reductase in red blood cells (P < 0.01), and inhibit the formation of glycation products significantly in model rats induced by D-galactose (P < 0.01). Also, puerarin can decrease the content of AGEs in brain and the level of calcium ions in brain cells (P < 0.05, P < 0.01), and decrease lesions degree in mitochondria in brain hippocampus cells.

CONCLUSIONPuerarin can produce the protective effects on glycated brain damages through inhibiting the glycation reaction in rats induced by D-galactose.

OBJECTIVETo find out potential molecular targets for gallbladder carcinoma diagnosis and treatment by analyzing and comparing the proteins expressed in human gallbladder carcinoma tissue and benign gallbladder tissue.

METHODSProteomic analysis of 6 human gallbladder carcinoma tissues and 6 benign gallbladder tissues was carried out. Total proteins of the carcinoma tissue and benign gallbladder tissue were separated by two-dimensional gel electrophoresis (2-DE). The differentially expressed proteins were analyzed and identified by matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS). Immunohistochemistry was used to examine the expression of PEBP1 protein in an independent series of samples.

RESULTSProtein extracts of individual samples in each type of tissues were separated on two-dimensional gels. There were forty six differentially expressed proteins in the gallbladder carcinom tissues. Seventeen proteins were successfully identified by MS, in which nine proteins were overexpressed in tumors while the other eight proteins were underexpressed. The increased level of PEBP1 protein in gallbladder carcinoma was further confirmed by immunohistochemical analysis.

CONCLUSIONSeventeen differentially expressed proteins were successfully characterized by comparative proteomic analysis. Those results may provide scientific foundation for screening the molecular biomarkers which can be used in diagnosis and treatment of gallbladder carcinoma, as well as to improve its prognosis and provide a new clue for carcinogenesis research of gallbladder carcinoma.

OBJECTIVETo explore the potential molecular targets for diagnosis and treatment of gallbladder cancer by analyzing and comparing the proteomes expressed in human gallbladder cancer and benign gallbladder tissues.

METHODSThe proteins expressed were analyzed using two-dimensional gel electrophoresis. The differentially expressed proteins in tumors were also analyzed by mass spectrometry (MS). AnnexinA3 expression was examined by streptavidin peroxidase immunohistochemical technique on paraffin-embedded tissue sections from 50 patients of gallbladder cancer and 38 cases of chronic eholecystitis.

RESULTSProtein extracts of individual sample in each type of tissues were separated on two-dimensional gels. There were forty six differentially expressed proteins in the tissue samples of gallbladder cancer. Seventeen proteins were successfully identified by MS, in which nine proteins were overexpressed in tumors and the other eight proteins were underexpressed. The positive expression rates of annexinA3 in gallbladder cancer was significantly higher than that in chronic cholecystitis, and the difference was statistically significant (74.0% vs 21.1%, P < 0.01). In the gallbladder cancer, no correlation was obtained between annexinA3 and age, gender or histologicl type (P > 0.05), but overexpression of annexinA3 correlated significantly with those cases with a lower histological grading (40.0% vs 82.5%, P < 0.05); lymph node or distant metastasis (40.9% vs 100%, P < 0.05); or a shorter survival time after operation (50.0% vs 93.8%, P < 0.05).

CONCLUSIONSSignificant discrepancies in protein expression exist among gallbladder cancer and benign gallbladder tissues. AnnexinA3 plays an important role in the initiation and progression of human gallbladder cancer.

BACKGROUNDResection of sacral chordomas is challenging. The anatomy is complex, and there are often no bony landmarks to guide the resection. Achieving adequate surgical margins is, therefore, difficult, and the recurrence rate is high. Use of computer navigation may allow optimal preoperative planning and improve precision in tumor resection. The purpose of this study was to evaluate the safety and feasibility of computer navigation-aided resection of sacral chordomas.

METHODSBetween 2007 and 2013, a total of 26 patients with sacral chordoma underwent computer navigation-aided surgery were included and followed for a minimum of 18 months. There were 21 primary cases and 5 recurrent cases, with a mean age of 55.8 years old (range: 35-84 years old). Tumors were located above the level of the S3 neural foramen in 23 patients and below the level of the S3 neural foramen in 3 patients. Three-dimensional images were reconstructed with a computed tomography-based navigation system combined with the magnetic resonance images using the navigation software. Tumors were resected via a posterior approach assisted by the computer navigation. Mean follow-up was 38.6 months (range: 18-84 months).

RESULTSMean operative time was 307 min. Mean intraoperative blood loss was 3065 ml. For computer navigation, the mean registration deviation during surgery was 1.7 mm. There were 18 wide resections, 4 marginal resections, and 4 intralesional resections. All patients were alive at the final follow-up, with 2 (7.7%) exhibiting tumor recurrence. The other 24 patients were tumor-free. The mean Musculoskeletal Tumor Society Score was 27.3 (range: 19-30).

CONCLUSIONSComputer-assisted navigation can be safely applied to the resection of the sacral chordomas, allowing execution of preoperative plans, and achieving good oncological outcomes. Nevertheless, this needs to be accomplished by surgeons with adequate experience and skill.
