OBJECTIVETo evaluate the therapeutic effect of Compound Xuanju Capsule on type III prostatitis.

METHODSA total of 242 patients with type III prostatitis diagnosed by the NIH criteria were randomly divided into an experimental and a control group of equal number, the former treated with Compound Xuanju Capsule + Tamsulosin Hydrochloride, and the latter with Quinolinone antibiotics + Tamsulosin and Hydrochloride, both for 6 months. After treatment, we assessed the therapeutic effects based on the NIH-CPSI scores and the improvement of relevant complications.

RESULTSAll the 242 patients completed the treatment. The total effectiveness rate was 77.69% (94/121) in the experimental group, 71.56% (78/109) in those with complications. In comparison, it was only 47.10% (57/121) in the control group, 31.78% (34/107) in those with complications. Both the NIH-CPSI scores and the improvement of complications were significantly higher in the experimental than in the control group (P < 0.05).

CONCLUSIONCompound Xuanju Capsule has a good therapeutic effect on type III prostatitis.

OBJECTIVETo evaluate the safety and efficacy between endoscopic papillary balloon dilatation (EPBD) and endoscopic sphincteropapillotomy ( EST) for common bile duct stones using meta-analysis method.

METHODSRandomizd controlled trials comparing EPBD with EST for common bile duct stones and published from January 1990 to July 2012 were recruited. This meta-analysis was conducted to estimate short-term and long-term complications. Fixed random effect model or random effect model was established to analyze the data.

RESULTSTwelve randomizd controlled trials were included in this analysis. These studies included 1865 patients, 925 of them were treated with EPBD and 940 were treated with EST. The analysis of basic characteristics of these included studies showed that: compared to EST, patients in the EPBD group were younger (OR = -1.16, 95% CI: -1.49 to -0.84, P = 0.00), while in two groups, there were no significant difference (P > 0.05) in gender proportion, average size of stones, number of gallstones, previous cholecystectomy, the number of merged duodenal diverticulum, common bile duct diameter, the total follow-up time. Also, compared to EST, the overall stone clearance in the EPBD group was lower (OR = 0.64, 95% CI: 0.42 to 0.96, P = 0.03), pancreatitis incidence was higher (OR = 2.67, 95% CI: 1.61 to 4.43, P = 0.00), incidence of bleeding (OR = 0.12, 95% CI: 0.04 to 0.34, P = 0.00), acute cholecystitis (OR= 0.39, 95% CI: 0.18 to 0.84, P = 0.02), total long-term complication rate (OR = 0.53, 95% CI: 0.36 to 0.77, P = 0.01), stone recurrence rate more than a year were lower (OR= 0.48, 95% CI: 0.26 to 0.90, P = 0.02). While in two groups, there were no significant difference (P > 0.05) in the stone removal on 1 '' attempt, the total near-term complications and acute cholangitis.

CONCLUSIONSOn the basis of lower rates of bleeding, EPBD seems to be preferred strategy over EST for endoscopic remove of common bile duct stones in patients who have coagulopathy. Although stone recurrence rate more than a year of EPBD is lower, but the overall stone clearance rate is lower and the risk of pancreatitis is higher than that of EST.

Hepatocyte growth factor (HGF) pretreatment could protect multiple cell types from apoptosis induced by various damages including oxidative stress. The present study was designed to investigate the protective effect of HGF on rat cortical neurons against apoptosis induced by hydrogen peroxide (H2O2) in culture, and then to explore whether HGF could influence the mitochondrial pathway of apoptosis. Primary rat cortical neurons were isolated from Sprague-Dawley rats and cultured in serum free medium containing 2% B27 and Neurobasal-A. To mimic the oxidative stress damage, cortical neurons were exposed to 100 mumol/L H2O2 for 4 h. To explore the effects of HGF on the neurons subjected to H2O2 injury, cells were pretreated with HGF 15, 30, 60 ng/mL for 24 h, respectively, and then exposed to 100 mumol/L H2O2 for 4 h. The cell viability was measured by MTT colorimetric assay and cell injury was evaluated by lactate dehydrogenase (LDH) leakage rate. Apoptotic cells were detected by Hoechst 33258 staining and Annexin V-FITC/PI double labeled flow cytometry. The caspase-3 activity was assessed by colorimetry. The alteration of transmembrane potential of mitochondria was determined by confocal laser scanning microscopy. The expression of cytochrome C protein was measured by Western blot analysis. The results showed that H2O2 treatment significantly decreased the cell viability, increased LDH leakage rate and the percentage of apoptotic cells. Pretreatment of HGF at different concentrations (15-60 ng/mL) could remarkably increase the cell viability of neurons. Compared with that of H2O2 group (53.4%+/-7.4%), the cell viabilities of neurons treated with 15, 30, and 60 ng/mL HGF significantly increased to (69.3+/-6.4)%, (77.5+/-6.1)% and (82.9+/-9.3)% (P<0.05), respectively. HGF preincubation also evidently decreased the LDH leakage rate in cortical neurons damaged by H2O2. The results of Hoechst staining revealed that HGF pretreatment could significantly reduce the apoptotic rate of neurons. The apoptotic rate of H2O2 group was (62.8+/-7.1)%, while that of HGF groups decreased significantly to (34.8+/-8.4)%, (23.5+/-3.2)% and (18.6+/-4.5)% (P<0.05), respectively. The data from caspase-3 activity assay indicated that HGF preconditioning could also remarkably decrease the caspase-3 activity of neurons. In addition, in the presence of various concentrations of HGF, the decrease of transmembrane potential of mitochondria in neurons caused by H2O2 injury could be reversed. Moreover, as detected by Western blot analysis, HGF downregulated the expression of cytochrome C protein in neurons. These results suggest that HGF has a protective effect on rat cortical neurons against apoptosis induced by H2O2, which might be related to the inhibition of the mitochondrial apoptotic pathway and the suppression of the caspase-3 activity.

Objective To evaluate the application of “OmniView”, a new three-dimensional ultrasound technology, in displaying the fetal palate. Methods The three-dimensional volume data was acquired from 100 normal fetuses, analysed by OmniView technology with the facial midsagittal plane as the starting plane. The imaging of fetal palate was obtained in axial plane (through maxilla, oral cleft), coronal plane, oblique coronal plane (through piriform aperture, oral cleft, submental triangle), and the palate′s curved plane tiled imaging by drawing the anatomical lines on referenced sagittal plane (facial midsagittal plane). The volumes of ifve fetuses with cleft lip and palate were obtained and analysed by the same technology. Results The volume dataset of 91 (91.0%, 91/100) normal fetuses were acquired successfully, and analyzed by OmniView technology, the results of 91 normal fetal palate in different plane were: (1) In axial plane through maxilla, the visualization of alveolar process bow was 91 (100%, 91/91). It was shown as“C”shaped arcuate structure, the anechoic structure of alveolar socket could be seen on the bow, and the ifrst 6 alveolar sockets were displayed clearly. The visualization number of hard palate was 91 (100%, 91/91), it was shown as hyperechoic lfake between two sides of alveolar bones. In axial plane through oral cleft, the visualization number of soft palate was 81 (89.0%, 81/91), it was shown as a strip of soft tissue echo band. (2) In coronal plane, the visualization number of hard palate was 91 (100%, 91/91), it was shown as a strip of hyperechoic band and separated the oral and nasal cavity. (3) In oblique coronal plane through piriform aperture, the visualization number of hard palate was 91 (100%, 91/91), it was shown as a short strip of hyperechoic band. In oblique coronal plane through oral cleft, the visualization number of hard palate was 91 (100%, 91/91). In oblique coronal plane through submental triangle, the visualization number of hard palate was 91 (100%, 91/91). In the above two planes, the hard palate was shown as a strip of hyperechoic band, due to acoustic shadow behind the hard palate, the nasal cavity and nasal septum above the hard palate couldn’t be displayed. (4) In oblique coronal plane through piriform aperture, the visualization number of soft palate was 81 (89.0%, 81/91). The visualization number of uvula was 25 (27.5%, 25/91). The soft palate was shown as a lfake of soft tissue echo behind the hard palate, and the uvula was shown as papillary protrusions on the edge of the soft palate in the midline. In oblique coronal plane through oral cleft, the visualization number of soft palate was 81 (89.0%, 81/91). In oblique coronal plane through submental triangle, the visualization number of soft palate was 81 (89.0%, 81/91). In the above two planes, the soft palate was shown as a strip of soft tissue echo band, the soft tissue echo of fetal tongue was in the lower front of soft palate, and the anechoic region of nasopharynx was superior behind the soft palate. (5) In the curved plane tiled imaging of palate, the visualization number of alveolar process bow (primary palate) was 91 (100%, 91/91). The visualization number of hard palate was 91 (100%, 91/91). The visualization number of soft palate was 81 (89.0%, 81/91). the visualization number of uvula was 25 (27.5%, 25/91), the planar panorama of alveolar process bow, hard palate and soft palate could be visualized intuitively, the alveolar arch and hard palate were shown as bone-like hyperecho, and the soft palate was shown as soft tissue hypoecho. In iffteen cases′volume involved cleft lip and palate, all five cases of malformations were detected through three-dimensional data analysis, the position and range of the cleft palate could also be conifrm. Abnormal fetuses were all veriifed after induction of labor. Conclusions By three-dimensional ultrasound technology-“OmniView”, the axial and coronal plane of fetal palate could be obtained easily which was dififcult by two-dimensional ultrasound, and the special oblique coronal plane of secondary palate could be displayed easily. The panorama of the palate could be visualized intuitively though curved plane tiled imaging by drawing a line tracking the structure of the palate. This technology could simplify the ultrasound examination procedure of the fetal palate, reduce the operators′skill-dependence, and quickly evaluated the integrity of the fetal primary palate and secondary palate. For the cleft lip fetus, this technology can determine whether the cleft palate exist or not, together with their position and range.

Objective To explore the association between polymorphisms of adiponectin gene and the risk of ischemic stroke in Han population from the Northern parts of China.Methods TaqMan probe of RT-PCR was applied to detect the genotype frequency of single nucleotide polymorphism(SNPs)(rs266729 and rs2241766)of adiponectin gene in 357 ischemic stroke cases who developed the episode at first time and with 345 healthy controls.Logistic regression analysis was used to evaluate the relationship of each genotype of SNPs and ischemic stroke.Results Mutation of rs2241766(T＞G)increased the risk of ischemic stroke among all the samples(0R=1.55,P=0.01)and it was still the risk factor of ischemic stroke when analyzed by multi-factors logistic regression after each factor was adjusted(OR=1.55,P=0.00).The polymorphism of rs266729 was not related to the risk of ischemic stroke among all the samples(OR=1.13,P=0.57).However,the genotype GG of rs266729 increased the risk of ischemic stroke among female population(OR=3.25,P=0.04).Conclusion The variance of rs2241766 in adiponectin gene was related to the risk of ischemic stroke in Han population from the Northern parts of China and the genotype GG of rs266729 could possibly increase the risk of ischemic stroke in women of Han population from the Northern parts of the country.

OBJECTIVEChimeric human/bovine immunodeficiency virus (HBIV) cDNA was constructed by replacing HIV tat and LTR with bovine immunodeficiency virus (BIV) tat and LTR to study the activity of BIV tat and LTR in the chimerae.

METHODSThe target fragments of BIV tat, LTR and HIV gag, pol, env were respectively amplified by using PCR and sequentially inserted into pBluescript SK(+) vector.

OBJECTIVETo investigate the distribution of regulatory T-lymphocytes in the splenocytes cocultured with syngeneic low-immunogenic tumor cells, as compared with that of highly-immunogenic tumor cells, to investigate the mechanism underlining tumor evasion.

METHODSThree different immunogenic tumor cells were cocultured with syngeneic splenocytes individually to mimic cancer immunity in vitro. The proliferation response of splenocytes was measured by thymidine incorporation. The distribution of TR cells, CD4(+) IFN-gamma (+) T cells and CD4(+) IL-10(+) T cells were analyzed by flow cytometry. The secretion of IFN-gamma and IL-10 in supernatants was measured by ELISA assay.

RESULTSThe stimulation Index of splenocytes cocultured with syngeneic highly-immunogenic H22 or FBL3 was much higher than that of poorly immunogenic melanoma D5. In each group, stimulation Index of splenocytes cocultured with allogeneic tumor cells was higher than that of the corresponding tumor immunity model. In addition, compared with those of highly-immunogenic tumors, there were more TR, CD4(+)IL-10(+) and less CD4 (+)IFN-gamma(+) T cells in the splenocytes, and higher IL-10 and lower IFN-gamma levels in the supernatant of the splenocytes stimulated with low-immunogenic D5 cells.

CONCLUSIONPoorly-immunogenic tumor cells can induce the proliferation of TR cells, which may play an important role in tumor evasion.
