Objective To evaluate the value of p504S,CK34?E12 and p63 immunostaining for the diagnosis of benign and malignant lesions of the prostate. Methods Expression of p504S、CK34?E12 and p63 in benign and malignant lesions of the prostate was observed by microwave SP immunohistochemical method. Results Continuous positive expression of CK34?E12 and p63 was found in the acini and ducts of most benign prostatic hyperplasia, and few cases showed interrupted expression, but p504S staining presented negative reaction; Interrupted expression of CK34?E12 and p63 was found in high prostatic intraepithelial neoplasia cases, and was weekly positive or negative for p504S; CK34?E12 and p63 staining was positive in five atypical adenomatous hyperplasia cases, one case presented focally positive reaction by p504S; CK34?E12 and p63 staining was negative in forty prostatic carcinoma, but positive by p504S;The gleason histologic grading of prostate carcinoma was negatively related to expression of p504S. Conclusion Combined detection of p504S、CK34?E12 and p63 can be most helpful for diagnosis of prostate carcinoma, especially in needle biopsy specimen.

OBJECTIVE: To investigate the relationship between visceral syndrome differentiation in traditional Chinese medicine (TCM) and the changes of nutrition status or blood gas analysis in patients with chronic obstructive pulmonary disease (COPD). METHODS: Sixty patients with COPD in stable phase were divided into dysfunction of lung (DL, n=20) group, dysfunction of lung and spleen (DLS, n=16) group and dysfunction of lung, spleen and kidney (DLSK, n=24) group according to syndrome differentiation of TCM. Moreover, the basic electric rhythm, percentage of bradygastria in electrogastrogram (EGG), ratio of actual body weight (ABW) to ideal body weight (IBW) and serum albumin level were determined to evaluate the nutrition status of the patients with COPD. Blood gas analysis was made too. RESULTS: The basic electric rhythm values in the DL, DLS and DLSK groups were (56.20+/-13.24)%, (47.38+/-10.24)% and (41.35+/-10.01)%, respectively. Compared with the DL group, the basic electric rhythm values in the DLS and DLSK groups decreased obviously (P<0.05). The percentages of bradygastria in the DL, DLS and DLSK groups were (45.18+/-18.13)%, (46.31+/-15.83)% and (49.90+/-17.54)%, respectively, and there were no differences among the three groups (P>0.05). The incidence rates of ABW/IBW<90% in the DL, DLS and DLSK groups were 50%, 75% and 54.17%, respectively, and there were no differences among the three groups (P>0.05). The incidence rates of serum albumin less than 35 g/L were 20%, 37.5% and 54.17%, respectively, and there were no differences among the three groups (P>0.05). PO2 in the DLS group [(63.56+/-15.06) mmHg] and DLSK group [(63.17+/-19.05) mmHg] were decreased as compared with the DL group [(78.15+/-16.63) mmHg] (P<0.05). PCO2 in the DL, DLS and DLSK groups were (42.25+/-12.46) mmHg, (48.60+/-17.60) mmHg and (49.97+/-13.43) mmHg respectively, and there were no differences among the three groups (P>0.05). CONCLUSION: Several dysfunction organs described in TCM were involved in COPD followed by the increased severity, hypoxemia and PCO2. Dysfunction of gastrointestinal tract and malnourishment took place accordingly.

Objective To evaluate the clinical effects in treating periprosthetic femoral fractures classified Vancouver B2 with a cementless modular revision femoral prosthesis.Methods Twenty-six patients (7 males and 19 females with mean age of 66.5 years,range 60-69 years) who suffered from periprosthetic femoral fractures classified Vancouver B2 were treated with a cementless modular revision femoral prosthesis in hip revision and open reduction and internal fixation with cables or plates from March 2007 to February 2014.The previous femoral prostheses included 21 cementless and 5 cemented hip stems.The period from former procedures to fractures was 16 months,range from 7 to 32 months.Harris hip scores and numerical rating scales were analyzed statistically.Time of leaving bed,discharging,fracture union postoperative complications and radiographic imaging were also recorded.Results The operation duration were 143 (range 105-165) minutes.Blood loss volume was 450 (range 270-780) ml.Blood transfusion volume were 330 (range 0-800) ml.All patients were followed up at least two years,averagely 3.5 years after surgeries.All fractures healed at 6.5 (range 3-12) months averagely after surgeries.Harris hip scores improved significantly from 11.8±2.5 before surgeries to 80.3±5.3 one month and to 91.4±7.3 six months after surgeries separately (F=0.715,P=0.001).Numerical rating scales were 9.6±0.3,9.4±0.4 and 9.1±0.7 points averagely in aspect of information acquisition,postoperative pain control and function recovery respectively one month after surgeries.Average time of leaving bed and discharging from surgeries was 68.3 (range 51-75) hours and 6.5 (range 5-9) days respectively.No postoperative complications was found except dislocation in 1 hip,lower limb discrepancy in 1 hip,DVT in 1 hip,and heterotopic ossification in 3 hips.Conclusion Due to achieving prosthetic stability and fracture union,periprosthetic femoral fractures classified Vancouver B2 treated with a cementless modular revision femoral prosthesis combined with open reduction and internal fixation with cables or plates can reach good clinical outcomes.

Objective In order to investigate the mechanism of the remodeling of pulmonary vascular in hypoxic pulmonary hypertension,normobaric hypoxic rat model (FIO 2=10%)was used to observe the changes of fibronectin(FN)and leminin(LN)within the pulmonary artery by morphological methods. Methods The normobaric hypoxic chamber was used to establish the hypoxic rat model. The lungs were taken off and stained with immunohistochemical method.Some specimens were examined by electromicroscopy. Results Immunohistochemical analysis revealed progressive increase in the deposition of FN and LN,which was most prominent in hypoxia 7d group.The content of FN was higher than LN.Electromicroscope revealed that the SMC of tunia media had transitted from a contractile to a synthetic phenotype. Conclusion Long term hypoxic exposure resulted in increasing of FN and LN in the wall of pulmonary artery.These increase not only raise the tension and make thickening of the vessels themselves,but also provide an environment for the transition of SMC from a contractile to a synthetic phenotype.FN and LN played an important role in the remodeling of pulmonary vascular directly and indirectly.

OBJECTIVETo explore the effects of sacral canal injection on nerve root local inflammatory factors in rat model with lumbar disc herniation, in order to identify its mechanism of treatment.

METHODSForty-eight male SD rats were randomly divided into sham operation group(group A), model group (group B), Chinese medicine group(group C) and western medicine group(group D). There were 12 rats in each group. The model of lumbar disc herniation was established using compression and inflammatory stimulation in group B, C, D. All rats were given epidural catheterization and group A and B with physiological saline (1 ml/kg), group C with mixed liquor of 2% lidocaine and compound Danshen injections and physiological saline (2:2: 16) and group D with mixed liquor of 2% lidocaine and triamcinolone acetonide injection and physiological saline (2:2:16), once a week for a total of three treatments. Four rats were killed every 1 week after injection for once, and the inflammatory factors of tumor necrosis factor (TNF-alpha), prostaglandin E2 (PGE2), interleukin-l (IL-1) and interleukin-6 (IL-6) were detected by ELISA method.

RESULTSThe levels of TNF-alpha, PGE2, IL-1 and IL-6 in compressed nerve tissues in group B were increased than those of group A (P < 0.01). The levels of PGE2, IL-1 and IL-6 in group C and D were decreased than those of group B, and group D was much less(P<0.05). There was no significant difference in level of TNF-alpha among group B, C, D (P > 0.05).

CONCLUSIONCompound compression with inflammatory stimulation can lead to massive release of inflammatory mediators, such as TNF-alpha, PGE2, IL-1 and IL-6. Both injection with compound Danshen injections and triamcinolone acetonide injections by sacral canal can reduce the levels of part inflammatory mediators (PGE2, IL-1 and IL-6), and the effect of Glucocorticoid is better than Danshen (P < 0.05).
