OBJECTIVETo observe the effect of Zhibai Dihuang Decoction (ZDD) on mRNA and protein expressions of transient receptor potential family vanilloid subtype 1 (TRPV1) and transient receptor potential family vanilloid subtype 5 (TRPV5) in Ureaplasma urealyticum (UU)-infected rat semens and spermatogenic cells, and to explore the pathomechanism of UU-infected infertility and the intervention of ZDD.

METHODSTotally 45 were randomly selected from 60 4-5 months old SD rats. UU testicular infected animal models were set up after bladder inoculation of UU suspension. The remaining 15 rats were simultaneously injected with normal saline as a normal control group. After a successful modeling, UU infected model rats were randomly divided into the model group, the azithromycin group, and the ZDD group, 15 in each group. Rats in the ZDD group were administered with ZDD at the daily dose of 1 g/kg by gastrogavage. Rats in the azithromycin group were administered with azithromycin suspension at the daily dose of 0. 105 mg/kg by gastrogavage. Equal volume of normal saline was administered to rats in the normal control group and the model group. All medication was performed once daily for 21 successive days. Testes and epididymis were extracted after rats were killed and UU positive rates were compared among all groups. Sperm cells were separated using a mechanical separation technique. Sperm motility parameters were detected using color sperm motion detection system. mRNA and protein expressions of TRPV1 and TRPV5 in spermatogenic cells were determined by real-time quantitative PCR and Western blot.

RESULTSThe UU positive rate was obviously higher in the model group than in the normal control group [(86.7% (13/15 cases) vs. 0] P < 0.05). It was lower in the ZDD group [33.3% (5/15 cases)] and the azithromycin group [26.7% (4/15 cases)] than in the model group (P < 0.05). Compared with the normal control group, class A and B sperms were reduced, the linear velocity and the average velocity were significantly lowered, mRNA and protein expressions of TRPV1 and TRPV5 in spermated genic cells significantly decreased in the model group (P < 0.05). Compared with the model group, class A and B sperms were increased, linear and curve velocities and the average velocity were significantly elevated, mRNA and protein expressions of TRPV1 and TRPV5 significantly increased in the ZDD group and the azithromycin group (P < 0.05, P < 0.01). Compared with azithromycin group, class A and B sperms were increased, the linear velocity and the average velocity were significantly elevated, mRNA and protein expressions of TRPV1 and TRPV5 significantly increased in the ZDD group (P < 0.05, P < 0.01).

CONCLUSIONZDD could fight against UU infection and elevate semen quality, which might be associated with up-regulating mRNA and protein expressions of TRPV1 and TRPV5 in spermatogenic cells.

Background The experimental studies of venous thromboembolism (VTE) as an entity and the response of the pulmonary arterial endothelium after VTE are still rare.The objective of this study was to observe changes in the pulmonary arterial endothelium using a novel rat model of VTE.Methods Rats were allocated to the VTE (n=54) or control groups (n=9).The left femoral vein was blocked using a microvessel clip to form deep vein thrombosis (DVT).One,four or seven-day-old thrombi were injected into the right femoral vein to induce DVT-pulmonary thromboembolism (DVT-PTE).The rats were sacrificed 1,4 or 7 days later (Dn (1,4,7) Pn(1,4,7) subgroups (n=6)),and the lungs were examined using light and electron microscopy.Results On gross dissection,the rate of DVT formation was higher on day 1 (D1Pn:100％,18/18) than day 4 (D4Pn:83％,15/18; x2=5.900,P=0.015) or day 7 (D7Pn:44％,8/18; x2=13.846,P=0.000).On gross dissection,the positive emboli residue rate in the pulmonary arteries was lower in the D1Pn subgroup (39％,7/18) than the D4Pn (73％,11/15;x2=3.915,P=0.048) and D7Pn subgroups (100％,8/8; x2=8.474,P=0.004); however,light microscopy indicated the residual emboli rate was similar in all subgroups.Hyperplasia of the pulmonary arterial endothelium was observed 4 and 7 days after the injection of one-day-old or four-day-old thrombi.However,regions without pulmonary arterial endothelial cells and intra-elastic layers were observed one day after injection of seven-day-old thrombi.Conclusions This novel model closely simulates the clinical situations of thrombus formation and is ideal to study pulmonary endothelial cell activation.The outcome of emboli and pulmonary arterial endothelial alterations are related to the age and nature of the thrombi.

OBJECTIVEMost of Endobronchial tuberculosis (EBTB) of children is caused by the bronchial erosion from the scrofula close to the bronchus. Due to its complicated mechanism, pediatricians have limited knowledge on the endobronchial tuberculosis, which makes the misdiagnosis rate high. This work explored the clinical features and diagnostic methods of endobronchial tuberculosis (EBTB), to improve the understanding of this disease.

METHODA total of 102 cases with endobronchial tuberculosis (EBTB) were investigated by analyzing clinical and bronchoscopic features, imaging manifestation, PPD results and etiological examination; 71 cases were male, 33 were female, the youngest was 4 months old, and the oldest was 10 years old. The patients were treated in the fourth ward of the Department of Internal Medicine, Beijing Children's Hospital, Capital Medical University.

RESULTOf the 102 cases, 71 (69.6 percent) were infants and young children. (1) Age and clinical presentation: Infants and young children were more common, the main clinical manifestations were fever and cough, physical examination may find decreased breath sounds, wet and dry rale and wheezing. (2) In 81 cases who received CT there was bronchial obstruction, in 43 cases there were simultaneous manifestations of primary pulmonary tuberculosis (mediastinal and hilar lymph node enlargement and/or pulmonary consolidation), 21 cases had only manifestations of primary tuberculo. (3) The results of PPD: the positive rate was 95%. (4) Bronchoscopic feature: presence of mucosal swelling, caseous necrosis, bronchial stenosis/extrabronchial compression, granulomatous lesions and lymph node bronchial fistula. (5) Bacteriologic results: 21 patients were bacteriologically positive.

CONCLUSIONBronchial tuberculosis was more common in infants and young children, their major clinical manifestations were fever, cough, common findings on lung imaging was mediastinal and hilar lymph node enlargement and/or pulmonary consolidation, bronchial obstruction should be considered manifestations of bronchial tuberculosis, positive PPD should support the clinical diagnosis. Diagnosis can be confirmed by positive bacteriological tests.

Objective To optimize the supercritical carbon dioxide(SC-CO2)extraction of lipids from tempeh(TE-C)and further improve the lipid classes ratio. Methods The experimental parameters of SC-CO2 extraction including extraction temperature, pressure,and moisture content of tempeh were optimized using a Box-Behnken design combined with response surface methodology (RSM),according to the weighted extraction ratio of TE-C and lipid classes after the experimental results of single factors. Detailed chemical compositions of TE-C obtained by optimum conditions of SC-CO2 extraction were analyzed by high performance liquid chroma?tography with an evaporative light-scattering detector(HPLC-ELSD)and high performance liquid chromatography-atmospheric pres?sure chemical ionization mass spectrometry(HPLC-APCI-MS). Results TE-C was composed of three lipid classes:fatty acids(Ⅰ), diacylglycerols(Ⅱ)and triacylglycerols(Ⅲ). The optimum SC-CO2 extraction conditions of TE-C were 50℃extraction temperature, 25 MPa pressure,1.99%moisture content of tempeh and 1.5 hour extraction time. Conclusion The optimum value of RSM for SC-CO2 extraction was(5.97±0.15)g/100 g.
