Objective To investigate the expression of activator protein-1 (AP-1) in PBMCs from patients with dermatomyositis (DM) and glucocorticoid effect on the expression.Methods PBMCs were isolated from 15 normal human controls and 20 patients (including 12 patients with primary DM who had never received glucocorticoid treatment and 8 patients with recurrent DM who had stopped glucocorticoid treatment for more than 1 month),and classified into two parts:one was cultured in RPMI 1640 medium with dexamethasone of 80 μmol/L and 10％ calf serum for 48 hours,and the other was frozen at -80 ℃ and reserved.Electrophoretic mobility shift assay (EMSA) was carried out to detect the activity of AP-1 in these cells.Results The expression (grayscale area) of AP-1 in the PBMCs from the normal controls was 4.93 ± 0.15 mm2.A significant decrease was induced by the treatment with dexamethasone in the expression (grayscale area) of AP-1 from PBMCs of patients with primary DM and those with recurrent DM (5.59 ± 0.39 vs.30.23 ± 0.49 mm2,5.69 ± 0.39 vs.34.79 ± 0.61 mm2,F =13812.64,P ＜ 0.01 ).The activity of AP-1 was statistically higher in the PBMCs from patients with recurrent DM than in those from patients with primary DM before the treatment with dexamethasone (P ＜ 0.01 ).Conclusions The enhanced activity of AP-1 may be an important factor inducing the inflammatory reaction in and recurrence of DM.Glucocorticoids may suppress the AP-1 activity to a certain degree.

Conclusion Electroacupuncture and continuous acupoint infusion of analgesic drugs at Jiaji could produce obvious analgesic effect , the analgesia effect of continuous acupoint infusion at Jiaji is better than subcutaneous analgesia .

Objective To establish the quality standard of Shilong Qingxue Effervescent Granules. Method Rhizoma curcuma, flos sophorae, cornus officinalis and gamdir vine in Shilong Qingxue Effervescent Granules were identified by TLC. The content of gastrodin in Shilong Qingxue Effervescent Granules was determined by HPLC. Results The TLC spots were highly clear without the interference of negative samples and were reproductive. A good linear for gastrodin was in the range of 14～70 ?g/mL (r=0.999 9). The average recovery was 97.33% (RSD=0.63%). Conclusion This method is simple, rapid and accurate, and can be used for the quality control of Shilong Qingxue Effervescent Granules.

The arteries of the breasts of 25 Chinese female cadavers, injected with color latex, were dissected and observed by surgical microscope. These arteries originate from the first, second and third perforating branches of the internal thoracic artery. They were classified into five types. The two branch type occured most frequently (54%), and is musculoadenocutaneous in nature. The distribution of this type of artery is in four directions, one branch to the nipple, the second branch to the axilla, the third branch to the sternum and the last branch to the clavicle. The second perforating branch is the largest in diameter, 0.92 mm., the first and third perforating branches come next. The area of distribution of the second perforating branch is also the largest, 6265.50 mm2, and the third and first perforating branches come next. The first perforating branch crosses the 4 th rib in 52%, and that of the second perforating branch in 43%. The arteries supplying the medial portion of the breast have an extensive anastomoses (48%) with those arteries of the lateral portion.

The arterial blood supply of the lateral portion of the breasts was studied in 50 sides of 25 Chinese female cadavers. The results are obtained as follows: 1.the arteries leading to the lateral portion of the breast are constant. Among them, 38% originates from the lateral thoracic artery, 24% from the brachial artery and 15% from the axillary artery. 2.One branch type arteries were found in 28 breasts (56%),two branch type arteries in 20 breasts (40%) and three branch type arteries in 2 breasts (4%). 3.The average diameter of the arterial origin isl.37.06mm.the average length of the artery is 171.9?5.82 mm. and the average range of distribution is 52.8?6.18 mm. 4.Besides supplying the skin of the lateral portion of the breast, the artery also supplies the gland, areola and the nipple. 5.The branches arising from the axillary artery arc musculoadenocutaneous, and those arising from the brachial artery are adenocutaneous. 6.The average distance between the artery and the center of the nipple is 38.6?4.34 mm. 7.The arterial supply is rich in anastomoses with its surrounding arteries, especially with the papillary branches of the internal thoracic artery. 8.The arteries originating from the brachial artery have long pedicles and their location is superficial and constant. Lastly, clinical significance of these arteries were discussed.

The hepatocyte growth factor ( HGF) is a multifunctional growth factor, which produces multiple biological effects by binding to the c-Met acceptor. This article reviews the biological properties of HGF, particularly those correlated with male reproduction, including its abilities to promote testis embryonic development, spermatogenesis, and testosterone synthesis of Leydig cells. HGF may provide a new insight into the treatment of male hypogonadism and infertility.

Circulating cell-free nucleic acids are defined as extracellular DNAs or RNAs in blood with physiological or pathological origins. Previous studies showed that the concentration of cell-free nucleic acids in the blood of cancer patients is significantly higher than in healthy people. Further studies showed that the genetic and epigenetic alterations of circulating cell-free nucleic acids are relevant to cancer development and progression, including mutation, hypermethylation, loss of heterozygosity, change of integrity, and abnormal expression of microRNAs. Detection of circulating cell-free nucleic acids shows promising potential in cancer screening, diagnosis, personalized treatment, and prognosis.

Objective To investigate the aetiology of acute exacerbations of COPD (AECOPD),and the effects of moxifloxacin in the treatment of AECOPD.Methods Patients with stable COPD based on GOLD criteria were included in the study.Sputum collected at first exacerbation was analyzed for bacteria count and culture.IL-6,IL-8 and TNF-?were measured by enzyme- linked immunosorbent assay (ELISA).Eligible patients were randomized to receive moxifloxacin (400 mg qd for 5 days) or ce- faclor (250 mg q8h for 7 days).Efficacy parameters were evaluated at 7 and 14 days after treatment initiation and 1 year later. Results Of the 46 patients with moderate or severe COPD (male 38,moderate 24),21 (45.65%) were microbiologically evalu- able at baseline.The main pathogen was Haemophilus influenzae (10/21).Clinical efficacy rate was 87.0% in moxifloxacin group and 82.6% in cefaclor group.Bacterial eradication rate was 80.0% and 72.7% respectively.The difference between groups was not statistically significant in terms of clinical or microbiological efficacy.In moxifloxacin arm,the frequency of ex- acerbation was 2.6?1.0,significantly lower than control arm (3.5?1.4,P

Hepatitis virus NAT reagents are now widely used clinically. However, the qulity of domestic and foreign NAT reagents varies dramatically. The main reasons for these differences including the manufacture technique, test principle and assay procedure were discussed in this paper and current status of the quality control of the NAT reagents were also described. Finally, it was pointed out that strengthening public supervision and laboratory internal control are very important for the quality improvement of the domestic reagents.
