Objective To elucidate the possibility of diagnosing BOO with urodynamic data with indefinite P F findings in patients with BPH. Methods Some urodynamic data besides the P F fin dings were studied in BPH patients,and these were compared between the BOO group and the non BOO group. Results There were 252 patients with BOO and 52 patients without.200 patients had no definite P F findings.Several other parameters were compared between the BOO group and the non BOO group.The rate of prostatic plateau was 87.3% and 53.8%, respectively( P

Objective To evaluate the performance of polymerase chain reaction (PCR)‐based rapid detection of methicillin‐resistant S .aureus (MRSA) from the respiratory specimens of ICU patients in comparison with conventional sputum culture . Methods We collected 3 respiratory specimens from each patient simultaneously for bacterial culture ,fungal culture and PCR‐based detection of MRSA .The performance of the established PCR method was compared with the results of sputum culture in terms of sensitivity ,specificity ,positive predictive value (PPV) and negative predictive value (NPV) .Results The sensitivity , specificity ,PPV and NPV of PCR assay were 88 .9% ,73 .6% ,36 .4% ,and 97 .5% ,respectively ,which were lower than the reported results of PCR assay with nasal swabs .Conclusions The utility of PCR assay for active screening of MRSA from respiratory specimens still needs further supportive data .However ,PCR assay is somewhat informative in excluding MRSA infection or colonization because of its high NPV .

Objective:To investigate the regulation of acupuncture on γ-interferon (INF-γ) and tumor necrosis factor (TNF) of lung cancer-operative cases. Methods: to determine the INF-γ and TNF contents in the blood serum of lung cancer patients by double antibody sandwich immuno-enzymatic method (ELISA); to measure the INF-γ and TNF contents of 30 lung cancer patients in the acupuncture anesthesia group and 30 lung cancer patients in general anesthesia group before the operation and at the 8th days, the 12th day after the operation respectively and make comparison between the two groups. Results:The pre-operation INF-γ contents of the two groups showed no significant difference (P＞0.05); the post-operation INF-γ contents of the two groups showed significant difference at 8th day and 12th day after the operation (P＜0.05); the acupuncture anesthesia group was superior to the general anesthesia group; the self-comparison of the anesthesia group showed significant difference at the 12th day and 8th day after the operation (P＜0.05); the pre-operation TNF contents of the two groups showed no significant difference (P＞0.05) and the post-operation TNF contents of the two groups showed significant difference at the 8th day and 12th day after the operation (P＜0.05). Conclusion:Acupuncture can increase the serum INF-γ and TNF contents of lung cancer patients and therefore regulate the immunity of the patients.

Aim To investigate the influence of iridosides of cornus officinalis(ICO) on morphology, cell cycle and oxidative stress of glomerular mesangial cells(GMC) cultured with advanced glycation end products(AGEs). Methods GMC were incubated in culture medium containing AGEs in the presence of ICO and aminoguanidin for 48 hours. At the same time, the control and model groups were added. Then the cultured GMC were stained by mixed fluorescence liquid and observed under fluorescence microscope. Cell cycle of GMC were analyzed using flowcytometry. The content of MDA, activity of SOD and GSH-Px in GMC supernatant were measured. The level of ROS was detected using flowcytometry. Result Morphology analysis showed that the morphology and structure of normal GMC were normal. The structure of most cells in AGEs were unclear, cell counts increased largely and they grow intensively. Cell cycle analysis showed that cell percentage of S phase increased and G_0/G_1 reduced. The level of ROS, MDA remarkably increased, and SOD, GSH-Px activity reduced. When the ICO were added, cell morphology tended to be basically normal and cell counts decreased, the percentale of S phase also decreased. The level of ROS, MDA and the SOD, GSH-Px activity restored in comparison with the model groups. Conclusion ICO can prevent the cultured GMC from lesion caused by AGEs. ICO may protect GMC from AGES to retard the progression of diabetic nepropathy by partially inhibiting the occurrence of oxidative stress.

Objective To speculate the precipitating factors,clinical features and histopathological changes in patients with granuloma annulare (GA).Methods A study was performed in 53 patients with GA . Results The incidence of female was more prevalent than male in our study. The exposure of sunlight was found more relatedly in GGA than LGA.The onset age of GGA was inclined to be elder and GGA seemed to last longer.The histopathological study showed that palisading granuloma pattern accounted for 71.7% in all patients,and scattered histiocytic infiltration accounted for 28.3%.Such as cryotherapy,topical steroids were used for LGA and systemic administration was an alternative to GGA. Conclusions Ultraviolet may be associated with the development of generalized GA. The most common pattern is the palisading granuloma though the histopathological changes were variable.Topical therapy is effective in LGA,while the systemic therapy is mainly used for GGA.

Objective To evaluate the effect of peer educatio n program by the application of the peer education on human immunodeficiency vir us/aeguired immune deficiency syndrome(HIV/AIDS) prevention and the analysis of the change on knowledge, attitude and behavior about HIV/AIDS among technical sc hool students in Shanghai. Methods Three technical schools in Shanghai were selected randomly. Two classes of each school were selected randomly as education group and the students added up to 284.Two hundred and sixty-one students of another 2 classes in each school were selected as the interior control group. Some freshmen came from medical un iversity were carefully trained as peer educators to conduct the education inclu ding 6 models. The same questionnaires were carried before and after the educati on in both groups. Results After peer education the score of average knowledge abo ut reproductive health, HIV/AIDS, STD was significantly higher than before (P 0.05). Conclusions The conduction of the peer education on HIV/AIDS pr evention among technical school students is effective in promoting the knowledge level,but the change of attitude and behavior is a long term. So we highly adv ocate that not only the health education for HIV/AIDS especially safe sex shall be given and strengthened among technical school students in order to promote t he notion of self-protection but also the conception of care others especially t he HIV/AIDS.

A 76?year?old female patient complained of right chest pain for three months. CT scan showed a clump?like high?density shadow measuring 4.8 cm × 3.0 cm in size in the dorsal portion of the right lower lobe of the lung. Aspiration biopsy was performed, and biopsy samples were subjected to fungal culture and histopathological examination. Histopathological examination showed chronic granulomatous inflammation with hyaline septate hyphae. After 4?day culture, white villous dense colonies were formed on the Sabouraud′s agar medium. The center of the colonies was slightly elevated with wrinkles or radiating striae on the surface, and the bottom of the colonies was faint yellow in color. Microculture yielded abundant septate branched hyphae, and very few colorless hyaline quasi?circular spores. DNA sequencing of rDNA internal transcribed spacer (ITS) regions and β?tubulin genes was performed to identify the isolate, and antifungal susceptibility testing was carried out in vitro. The MEGA7.0 software was used to build phylogenetic trees of Aspergillus fumigatus complex and its closely related species. The isolate was identified as Aspergillus fumigatus by molecular biologic sequencing. The patient was diagnosed with pulmonary aspergilloma. After administration of itraconazole oral solution and vorionazole tablets, the condition got better obviously.

In this experiment, Hca-F or L615 elemene combo-TCV (H-TCV and L-TCV), H-TCV lysates, corynebacterium parvum (CP) were used to immunize 615 and Balb/c inbred mice, and their splenic DCs were prepared and pulsed in vitro with tumor cell lysates (H or L) and TCV lysates (TH or TL). The capacities of DCs to stimulate the proliferation of syngeneic nonadherent spleenic cells were tested with MTT assay. The results showed that the splenic DCs from normal mice in vitro pulsed with TH or TL could induced syngeneic noradherent splenic cells to proliferate (P＜0.01), while the H or L pulsed DCs could not. The splenic DCs from H-TCV or L-TCV or TH immunized mice re-pulsed in vitro with TH or TL exhibited stronger stimulating effects than the DCs from normal mice pulsed in vitro for the firth time pulsed with TH or TL (P＜0.01 or P＜0.05); The capacities of DCs to induce proliferation of syngeneic nonadherent splenic cells could be further enhanced by CP immunization, especially when were pulsed with TH (P＜0.01). Normal inbred 615 mice were transferred with DCs pulsed with lysates of elemene TCV (TDCs) or pulsed with lysates of Hca-F tumor cells (HDCs) on day 7 before challenged with lethal dose of live Hca-F cells, significant adoptive immunoprotective effects were seen, with 61.6% tumor inhibition rate and 25% survival in TDC adoptive transfer group. This study indicated that DCs might play a role in the mechanisms of active immunization and pulsing DCs with lysate of elemene combo TCV and isolating DCs from elemene combo TCV immunized mice were useful methods for DCs vaccine preparation.

Objective To investigate the effect of normothermic machine perfusion (NMP) in alleviating the ischemia reperfusion injury of DCD grafts.Methods Twenty-four Bama miniature pigs were randomly divided into two groups.The donor livers were harvested after 40-min cardiac arrest and preserved for 6 h by NMP preservation in the group A,or with cold UW solution in the group B,respectively.Then,liver transplantation was performed in both groups.Choleresis and the perfusate biochemical markers in the group A were detected during NMP.The recipient survival rate,the serum biochemical markers as well as the histopathological changes of the donor livers were compared between these two groups.Results The levels of ALT,AST and LDH in the perfusate were slightly elevated at the beginning of NMP and maintained at a stable level thereafter.The average choleresis rate was 10.3 ± 3.61 mL/h.The histological structures of the donor livers were normal after 6-h NMP preservation.The survival rate of the recipient pigs was 100％ and 0 in the group A and group B,respectively.After reperfusion,the levels of serum ALT,AST,LDH and lactic acid in the group A were significantly lower than those in the group B (P ＜ 0.05).The pathological examination demonstrated that the hepatocyte injury in group A was slighter than that in group B after 6-h preservation and reperfusion.Conclusion NMP storage could significantly alleviate the ischemia reperfusion injury of pig DCD livers and improve the prognosis of liver transplantation.
