Objective To investigate the effecacy of open reduction internal fixation in cases with rib fracture. Methods The pain scores,respiratory related clinical indicators change of 81 rib fractuure cases underwent open reduction internal fixation surgery were ob-served. A comparison was made between the surgical group and the non-surgical group of 37 cases on pain scores trend and hospital stay. Re-sults All operations were successfully completed and postoperative recovery was good. Postoperative pain scores and respiratory rate was sig-nificantly lower(P=0. 000),Oxygen saturation was significantly higher(P=0. 002),the proportion of expectoration difficult,dyspnea and ac-tivities inconvenience were significantly lower(P<0. 05). Pain scores of surgical group significantly decreased after surgery peak hours that was the fourth day hospitalized,but the overall decline of pain scores in non-surgical group was slow. The hospital stay between the surgical group and the non-surgical group was not significantly different(P=0. 084). Conclusion The efficacy of open reduction internal fixation is significant to rib fracture with exact surgery indications,and appropriate timing of surgery is the fourth day after admission.

Objective To analyze the epidemiological characteristics of Mycobacterium tuberculosis by enterbaeterial repetitive intergenic consensus-polymerase chain reaction(ERIC-PCR)DNA fingerprint.

OBJECTIVE Licorice is used throughout the world as a traditional herbal remedy. Ac-cording to Chinese traditional medicine licorice alone can be used to treat inflammation.Although there have been some studies investigated the anti-inflammatory ingredients of licorice, but for the potency of flavonoid glycoside and their aglycones on inflammation are not evaluated.This study was designed to assess the contributions of licorice flavonoid glycosides and their aglycons to its anti-inflammatory and hypnotic effects. METHODS For the flavonoid aglycone's enrichment, the extract of licorice (EL) was fermented in submerged culture of the edible fungus Grifola frondosa HB0071 mycelia which can produce β-glucosidase and catalyze the flavonoid glycosides to aglycones.EL and fermented extract of licorice (FEL) were used in this study. The anti-inflammation test was carried out in arachidonic acid (AA)-induced ear edema model and the hypnotic test was performed by using electroencephalogram (EEG)analysis method in normal freely moving SD rats.The chemicals constituents were analyzed by HPLC.RESULTS During fermentation,the falvonoid glycosides of licorice were hydrolyzed by the time process.Along with fermentation time,the concentration of the major flavonoid glycosides,liquiritin and isoliquiritin were decreased obviously, and simultaneously their aglycons, liquiritigenin and isoliquiriti-genin were remarkably increased in FEL.Moreover,the content of another major constituent glycyrrhi-zic acid and glycyrrhetinic acid were not changed after the fermentation. In AA-induced mice ear ede-ma test,after topical application,FEL(effective dose range:5-20 μg·ear-1)showed more potent inhibito-ry activity than EL(effective dose range:25-100 μg·ear-1).On the other hand,oral administration of EL and FEL exhibited the same hypnotic potency and both enhanced the total sleep time including rapid eye movement (REM) sleep and non-REM sleep time. CONCLUSION These results suggested that the enrichment of flavonoid aglycons such as liquiritigenin and isoliquiritigenin enhanced the anti-inflam-matory potency of licorice extract,and this potentiation has nothing to do with glycyrrhizic acid or glycyr-rhetinic acid.In addition,enrichment of flavonoid aglycones did not alter the hypnotic effect of licorice.

Objective To follow-up the imaging findings in the SARS.Methods The serial thoracic images in 15 cases of SARS were taken in 7 months from the onset of this disease,and the imaging findings were analysed.Results The detecting rate of the pathological changes in lung by spiral CT was higher than that of X-ray film(t = 5.5228,P

Bacille Calmette-Guerin (BCG) induces potent Th1 responses with the help of interleukin (IL)-10 and IL-12 released from dendritic cells (DCs), and suppresses Th2- associated allergic reactions. However, there are still some controversies on therapeutic effects of BCG in asthmatics. This study investigated whether BCG administration to DCs suppresses IL-5 production from T cells in atopic asthmatics. DCs derived from peripheral blood of subjects were cultured with or without BCG and Dermatophagoides farinae extract. Some DCs were co-cultured with T cells in the presence of BCG or the above culture supernatants. In the atopic asthmatics, BCG significantly increased IL-10 and IL-12 production from DCs. In the presence of D. farinae extract, BCG further increased IL-10 production. BCG-induced IL-10 production was significantly higher in the atopics (n=14) than in the non-atopics (n=9). Both BCG and the BCG-treated DCs culture supernatant significantly increased IFN-gamma production from T cells. Both BCG and the supernatant from DCs+BCG+D. farinae co-cultures significantly decreased IL-5 production (all p<0.05), but the supernatant from DCs+BCG co-cultures did not. In conclusion, administration of BCG together with D. farinae extract effectively decreased IL-5 production from T cells, probably through the action of IL-10 and IL-12 released from DCs in D. farinaesensitive asthmatics.

OBJECTIVETo investigate the influence of chronic prostatitis/chronic pelvic pain syndromes (CP/CPPS) on male health.

METHODSWe conducted investigations among 200 cases of CP/CPPS, aged 20 -59 years and randomly selected from 650 out-patients, using an anonymous questionnaire including such items as the patients'age, height, body weight, disease duration and treatment, the results of EPS and semen determinations, and the scores on NIH-CPSI, IIEF-5 and Symptom Checklist (SCL-90).

RESULTSAccording to the 198 valid questionnaires collected, CPSI scores showed 56 (28.3%) cases to be mild, 98 (49.5%) moderate and 44 (22.2%) severe. Sperm density and motility (grade a + b) were reduced in 38 (19.2%) and 47 (23.7%) cases, respectively. IIEF-5 revealed ED in 41 (20.7%) cases, of which 58.5% were mild. Psychological abnormality was found in 94 (47.5%) cases, including anxiety, depression, sensitiveness and so on. NIH-CPSI scores were positively correlated with psychological symptoms and ED (r = 0.25, P < 0.05; r = 0.12, P < 0.05), but not significantly related with sperm density and motility (P > 0.05).

CONCLUSIONThe influence of CP/CPPS is obvious on male psychology but mild on penile erection and not significant on semen. Integrated physiological and psychological therapy is recommended for the treatment of CP/CPPS.

OBJECTIVEHuman rhinovirus (HRV) is the most common respiratory pathogen, which causes not only acute respiratory infection and community acquired pneumonitis in children, but also asthma episode and deterioration. However, the detection of respiratory pathogen, which mainly focuses on respiratory syncytial virus, influenzaviruses A and B, parainfluenza viruses 1-3 and adenoviruses, does not include HRV yet by now in China. The absence of detection method limits the clinical understanding of HRV pathogenicity, and causes unreasonable use of antibiotics. This study aimed to establish a one-step reverse transcription (RT) PCR system for detecting specific fragment of HRV RNA, and to analyze the sequences of amplicons.

METHODSA pair of degenerate primers based on the HRV highly conserved 5'' noncoding region (NCR) were used to develop a one-step RT-PCR system for detecting HRV RNA in nasopharyngeal aspirates from 78 children with acute respiratory tract infections in the spring of 2004. All the positive PCR products were sequenced, and the sequences of the nucleotides were analyzed by using biological software and compared with those in the GeneBank.

RESULTSEleven (14.1%) of 78 samples were positive on RT-PCR, these patients were clinically diagnozed as upper respiratory tract infection (n = 7), bronchitis (n = 3) and bronchopneumonia (n = 1), respectively. Compared with the sequences of clinical and standard HRV viruses in the GeneBank, the nucleotide sequences of these 11 amplicons shared high homology of 89%-95.5%. Within the 11 amplicons, nucleotide identity varied from 75.2% to 91.8%, and the ratio of genetic variation was from 8.8% to 31.0%, which occurred in highly conserved regions and usually showed single nucleotide mutation in some special locations. These 11 amplicons attribute to the two branches of HRV cladogram, respectively. Most of mutations in highly conservative domain occurred on single ribonucleotide, mainly as transversion (C/G, A/G) and transition (T/C, A/G), some were mutations among 3 bases (A/C/G, A/T/G, A/C/T). And a few mutations involved two nearby ribonucleotide which were also found in highly conservative domain. However, ribonucleotide deletion and insertion were usually found in highly variable domain.

CONCLUSIONThe findings showed that this one-step RT-PCR system was highly specific, rapid and convenient for the detection of HRV RNA in nasopharyngeal secretions of patients with acute respiratory tract infections and that the genome of HRV viruses was highly variable.
