Objective To investigate whether B-cell activating factor (BAFF) involved in the patho-genesis of lupus nephritis (LN) by regulating phosphoinositide 3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/Akt/mTOR) signaling. Methods Twenty-eight lupus nephritis patients and 20 controls were included in this study. The clinical data were collected. BAFF levels in plasma were measured by ELISA, and the relationship between systemic lupus erythematosus disease activity index (SLEDAI) and BAFF were analyzed. The mRNA and protein levels of BAFF, phosphorylated-PI3K (p-PI3K), phosphorylated-Akt (p-Akt), phosphorylated-mTOR (p-mTOR) and Bcl-2 in kidney tissues were measured using real-time polymerase chain reaction (RT-PCR) and Western blotting. Data were analyzed using Mann-Whitney U test and Spearman correlation analysis. Results ①Plasma BAFF levels were significantly higher in LN patients [(580 ±45) ng/L] compared with controls [(208 ±30) ng/L](Z=-5.856, P<0.01), and significant positive correlation was found between plasma BAFF levels with SLEDAI (r=0.723, P<0.01). ② Plasma BAFF level in LN patients was positively correlated with 24 h UP and anti-dsDNA titers (r=0.381, 0.461, P<0.05). The protein level of BAFF in kidney tissues was positively correlated with 24 h UP and anti-dsDNA titer (r=0.469, 0.489, P<0.05).③The mRNA levels of BAFF, p-PI3K, p-Akt, p-mTOR and Bcl-2 in kidney tissues were increased in patients compared to controls[5.8±1.8 vs 2.1±0.7, Z=-4.915, P<0.01;6.7±0.9 vs 1.71±0.53, Z=-5.857, P<0.01;5.6±0.9 vs 1.8 ±0.5, Z=-5.751, P<0.01; 5.6 ±1.4 vs 1.6 ±0.4, Z=-5.291, P<0.01; 2.11 ±0.36 vs 1.33 ±0.22, Z=-4.844, P<0.01].④The protein levels of BAFF, p-PI3K, p-Akt, p-mTOR and Bcl-2 in kidney tissues were increased in patients compared to controls [0.72±0.19 vs 0.31±0.05, Z=-4.747, P<0.01;0.73±0.11 vs 0.33±0.09, Z=-5.834, P<0.01;0.77±0.06 vs 0.22±0.07, Z=-5.855, P<0.01;1.18±0.27 vs 0.47±0.13, Z=-5.416, P<0.01;2.08±0.37 vs 1.32±0.18, Z=-4.998, P<0.01]. Conclusion The findings of this study indicate that BAFF may participate in the pathogenesis of LN by regulating PI3K/Akt/mTOR signaling.

Aim To prepare and characterize a monoclonal antibody against recombinant glutathione S-transferase(GST) for purifying GST fusion protein. Methods The GST-follistatin fusion protein was expressed by using a pGEX4T-1 expression vector in Escherichia coli BL21 and purified by glutathione-resin affinity column chromatography. Then female Balb/c mice were immunized with the GST-FS, The immunized splenocytes were fused with NS-1 hybridoma cells. Dreparation of the mAb was used by conventional hybridoma techniqal. The mAb purified by protein A, was culpled with Sepharose4B to purify further GST fusion protein by affinity chromatography. Results The SDS-PAGE showed that the GST fusion protein could be purified effctively by specific mAb affinity chromatography as same as by glutathione-resin affinity chromatography. Conclusion mAb affinity chromatography will be a ecnomical and useful method and it can be used for secondary purification of GST fusion protein following glutathione-resin affinity chromatography.

Objective:To explore whether perioperative intravenous flurbiprofen axetil can reduce the incidence and intensity of chronic pain for breast cancer atfer surgical treatment. Methods:This randomized, double-blind, controlled trial enrolled 60 patients undergoing mastectomy and axillary lymph node dissection under general anesthesia. All patients accepted Hospital Anxiety and Depression Scale (HAD) tests the day before the surgery to evaluate depression and anxiety. hTe patients were randomly assigned to receive either 50 mg lfurbiprofen axetil intravenously 15 minutes before the surgical incision and 6 hours later (group F) or intravenous 5 mL intralipid as a control (group C). All patients received patient-controlled intravenous analgesia (PCIA) with fentanyl postoperatively. Peripheral venous blood samples were drawn before the surgery, at 4 and 24 h atfer the surgery to detect the plasma level of PGE2 and tumor necrosis factor-α(TNF-α). Postoperative fentanyl consumption, Numerical Rating Scale (NRS) scores and adverse effects were recorded at 2, 6, 12, 24 and 48 h after the surgery. hTe duration and intensity of pain were followed up by telephone at the 2nd-12th month atfer the surgery. Results:The incidence of pain at 2, 4, 6, and 12 months after the breast surgery was 33%, 20%, 15%, and 10%, respectively, and the average pain score was 0.77, 0.57, 0.28, and 0.18, respectively. Compared with group C, the scores of pain in group F were significantly lower at 2, 4, 6 and 12 months postoperatively (F=7.758, P=0.007). The incidence of pain in group F was significantly lower at 2, 4 and 6 months postoperatively (P<0.05). There was no significant difference in the incidence of pain between the groups at 12 months postoperatively (P>0.05). Preoperatively and at 4 and 24 h atfer the surgery, there was no signiifcant difference in the level of TNF-αbetween the two groups (F=0.530, P=0.470);but plasma concentration of PGE2 in group F was significantly lower than that in group C (F=5.646, P=0.021). No patients developed abnormal bleeding, peptic ulcer, impaired liver or renal function and respiratory depression. Conclusion:Perioperative intravenous infusion of 100 mg flurbiprofen axetil can decrease the intensity and incidence of chronic pain for breast cancer atfer surgical treatment.

BACKGROUND:It is stil disputed about the treatment of subacromial impingement syndrome at present, arthroscopic subacromial decompression or open subacromial decompression. OBJECTIVE:To assess the clinical therapeutic effects of arthroscopic subacromial decompressionversus open subacromial decompression in the treatment of subacromial impingement syndrome. METHODS:Controled trials on arthroscopic subacromial decompressionversus open acromioplasty in the treatment of subacromial impingement syndrome were colected in different databases through computer search. There was no limitation for language, randomized controled trials or blinded studies. At last, the meta-analysis was conducted by using RevMan5.0 software. RESULTS AND CONCLUSION:Four randomized controled trials and six non-randomized controled trials were included in this study, involving 583 patients with subacromial impingement syndrome. The results of meta-analysis prompted that as to the hospital inpatient days and time until return to work, the group of arthroscopic subacromial decompression was shorter than open subacromial decompression. However, as to the postoperative shoulder functional scores, the operative time, patient’s satisfaction, and the rate of excelent and good results of postoperative UCLAs, there were no significant statistical differences between two groups. Due to the certain limitations and deficiencies of the quantity and quality in the included trials, there must stil need large-sample, multi-centered, high-quality randomized controled trials to confirm these results.
