The effects of sodium salicylate on the expression of heat shock protein 27 (HSP27) during oxidative stress in tissue-cultured human lens epithelial cells were investigated. Cultured human lens epithelial cells (HLB-3) were divided into 3 groups: control group (group A), oxidation injury group (group B) and sodium salicylate group (group C). Apoptosis of human lens epithelial cells cultured in vitro was induced in the presence of 150 micromol/L H2O2. Cells viability and the expression of HSP27 were analyzed. Viability of the cells was measured by methyl thiazole tetrazolium (MTF) chromatometry. The expression of HSP27 in HLB-3 cells was detected by using immunohistochemistry and image analysis system. Sodium salicylate could induce the expression of HSP27, and the cells viability in group C was significantly higher than in group B (0.2667+/-0.01414 vs 0.2150+/-0.01080, P=0.012<0.05). The average gray value of HSP27 in group B was less than that in group C (P=0.000<0.05). The increased expression of HSP27 by sodium salicylate might play an important role in the protection of hydrogen peroxide-induced injury of human lens epithelial cells, suggesting that sodium salicylate could suppress, at least in part, the apoptosis of human lens epithelial cells.

Objective To evaluate the efficacy of uterosacral ligament amputation in combination with lesion electrofulguration under laparoscope in the treatment of endometriosis-related dysmenorrhea. Methods A total of 86 patients with endometriosis-related dysmenorrhea were treated by uterosacral ligament amputation combined with electrofulguration of lesions under laparoscope from March 2000 to August 2004 in this hospital. Among the 86 patients, enucleation of ovarian endometriotic cysts and electrofulguration of pelvic endometriotic lesions were also simultaneously conducted in 37 patients, and electrofulguration of all visible pelvic endometriotic lesions was also performed in the rest of 49 patients. The operation was accomplished with the aid of the placement of an infrared ureteral detector in 3 patients because of the thickening of the uterosacral ligament and local adhesion. Results The 86 patients were followed for 6~48 months (median, 23 months). Dysmenorrheal completely disappeared in 36 patients, partially subsided in 29, and remained unchanged in 21, the effective rate being 75.6% (65/86). Conclusions Uterosacral ligament amputation combined with electrofulguration of lesions under laparoscope is effective for the treatment of endometriosis-related dysmenorrhea.

Unusual dTDP-sugars are key intermediate in many pathogenic bacteria. In this study, negative-ion electrospray tandem mass spectrometry (ESI-MS-MS) with collision-induced dissociation (CID) was used to study the fragmentation characteristics of six unusual nucleotide diphosphate sugars. The results indicated the major fragment of the six unusual nucleoside sugars observed in the ESI-MS-MS spectra resulted from cleavage of diphosphate moiety and their characteristic fragment ions at m/z 401, 383, and 321, correspond to [TDP-H] together with fragment ions resulting from the loss of water and phosphate moiety, respectively. Furthermore, 4-position substituted change of unusual sugar rings affected the stability of two important characteristic fragment ions of [glycosyl-1"-PO3](-) and [glycosyl-1"-P2O6](-).

Objective To investigate the effects of dexmedetomidine on plasma IL-8,IL-10 level and lung AQP1 expression in patients undergoing one lung ventilation(OLV).Methods Forty patients,ASA Ⅰ or Ⅱ,scheduled for lung cancer radical surgery were randomly divided into two groups:control group (group C)and dexmedetomidine group (group D).In group D,dexmedetomi-dine 1 μg/kg (initial dose)was given over more than 10 min before anaesthesia induction,followed by continuous infusion at 0.5 μg·kg-1 ·h-1 until 30 min before the end of operation.In group C,the e-qual volume of normal saline was infused.Blood samples were collected at immediately before OLV (T1 ),30 (T2 ),60 (T3 ),120 (T4 )min of OLV,30 min after lung inflate (T5 )and 2 h after opera-tion (T6 )for determination of plasma IL-8 and IL-10 levels.Lung tissues were obtained at T1 for de-termination of AQP1 expression.Results Compared with the value at T1 ,plasma IL-8 levels in group C at T3-T6 and in group D at T3-T5 were increased,plasma IL-10 levels were increased in both groups at T2-T5 (P <0.05).Compared with group C,plasma IL-8 levels at T3-T6 were decreased and plasma IL-10 levels at T2-T5 were increased in group D (P <0.05).Compared with the value at immediately before OLV,the expression of AQP1 was decreased at the time of lobectomy of lungs in group C (P<0.05).Compared with group C,the expression of AQP1 at the time of lobectomy of lungs in group D was increased (P <0.05).Conclusion Dexmedetomidine 1 μg/kg followed by continuous infusion at 0.5 μg·kg-1 ·h-1 can reduce inflammatory response,up-regulate the expression of AQP1 in pa-tients undergoing OLV.

Objective To explore the relationship of the expression level of monocyte Chemotactic protein-1 and nuclear factor κB(NF κB)with atrial fibrosis of atrial fibrillation patients with rheumatic heart disease.Methods About 200 mg right atrial tissue were taken from 26 patients with rheumatic heart disease undergoing valve replacement surgery and divided into sinus rhythm (SR) group (n=12) and atrial fibrillation (AF) group (n=14).Masson staining and atrial myocardial fibrosis markers were used to determine the level of fibrosis.The mRNA levels of cytokines in atrial tissue were measured by reverse transcription polymerase chain reaction (RT-PCR)The protein level of MCP-1 and phosphorylation of NFκB in atrial tissue were detected by Western blotting.Results Compared with SR group,the AF group showed that collagen volume fraction (AF:0.42 ± 0.03;SR:0.13 ± 0.02),the mRNA levels of myocardial fibrosis markers such as transforming growth factor (TGF)-β1,type Ⅰ collagen and type Ⅲ collagen,and cytokines such as IL-1β and TNF-α,and the protein level of MCP-1 (AF:0.170±0.003;SR:0.040±0.005) and level of phosphorylation of NF-κB (AF:0.35 ± 0.02;SR:0.12 ± 0.03) were significantly increased (all P＜0.05).In addition,the expression levels of cytokines,the protein expression level of MCP1 and the phosphorylation level of NF-κB were positively correlated with collagen volume fraction of the right atrial myocardial tissue (all P＜0.05).Conclusions Activation of NF-κB may induce the expression of MCP-1 in the myocardial tissue of patients with rheumatic heart disease,and sequentially stimulate the secretion of cytokines and extracellular matrix deposition,and finally participate in the occurrence and persistence of atrial fibrillation.
