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](-).

In recent years,nuclear medical imaging has become a routine examining technology.In general,angiographic medicine has to be injected into human body.Considering the short-coming of the manual injection,it seriously needs a injecting pump with the functions such as auto-control,push-pull injecting,synchronous injection of two injectors.

Objective To observe the relationship between the skin incision of anterior cruciate ligament(ACL) reconstruction and the sensory disturbance around the surgical incision of the leg.Methods From Oct 2007 to Jun 2008,223 patients underwent arthroscopy ACL reconstruction,among them 50 patients were followed-up and defined as four groups according to different types of skin incision.The area of skin sensory disturbance around the incision were measured and compared.Results Compared with transversal incision group(transversal incision for double bundle ACL reconstruction),vertical incision group(using hamstring or Bone-Patella-Bone autografl for ACL reconstruction) and posteromedial incision group(medial meniscus repair group),the length of incision in small incision group(using allograft for ACL reconstruction)was significant shorter(P<0.001).For the area of sensory disturbance,there were no statistics differences between small incision group and transversal incision group(P=0.800),and no statistics differences between vertical incision group and posteromedial incision group(P=0.316).But both small incision group and transversal incision group showed significantly smaller(P<0.05)area of sensory disturbance than vertical incision group and posteromedial incision group.Conclusion For ACL reconstruction,using small incision(allograft)and transversal incision could decrease the area of sensory disturbance of anterior tibial skin.

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 characteristics of chromosome karyotypes in patients with chronic myeloid leukemia (CML),and to provide help to individualized treatment.Methods The date of chromosome karyotypes of 313 patients and FISH of 45 of these patients with CML excluding Ph chromosome negative (Ph-) after treatment were collected from January 2014 to June 2015.Karyotypes were detected by R-banding.Results In the 313 cases,307 cases (98.08 ％) were Ph chromosome positive (Ph+) and 6 cases (1.92 ％) were Ph-.In the Ph+ patients,288 cases (93.81％) were classical Ph+,and 19 cases (6.19 ％) were variant rearrangements.There were 48 cases (15.34 ％) with additional chromosome changes in all patients,including 41 cases (13.10 ％) with classical Ph+ and 7 cases (2.24 ％) with variant rearrangements.The most common additional chromosome changes were in the following order:+der(22) Ph (35.42 ％),+8 (33.33 ％) and +21 (12.50 ％).The most frequent pattern of combination was +der(22) combined with +8 (16.67 ％),followed by +8 combined with +21 (10.42 ％).The proportion of pure Ph+ patients in chronic phase was higher than that of advanced phase,but proportion of classical Ph+ patients with additional chromosome changes in chronic phase was lower than that in advanced phase (x2 =1 11.55,P ＜ 0.01).The proportions of chronic phase and advanced phase patients with simple variant rearrangements were not different from those with complex variant rearrangements (P =0.582).The results of FISH in 45 cases were all positive,including 5 cases with 2 GIR1Y.Conclusion Karyotype analysis can reveal the instability of genetic and the characteristics of disease progression by identifying the evolution of Ph,which provides the basis for clinical doctors to choose suitable treatment.

OBJECTIVE: To investigate the effects of low-level laser irradiation on acupuncture points combined with iontophoresis against brain damage after middle cerebral artery occlusion (MCAO) in rats. METHODS: Sixty-nine SD rats were randomly divided into five groups, including normal group, sham operation group, model group, electro-acupuncture group and low-level laser irradiation on acupuncture points combined with iontophoresis group (LLLI group). The cerebral ischemia-reperfusion (I/R) model was established by thread embolism of middle cerebral artery. The rats in the LLLI group, as well as the electro-acupuncture group were given treatment as soon as the occlusion finished (0 hour) and 12, 24 hours after the occlusion. We observed the changes of neurological deficit scores and the body weight of the rats at different time. The activity of superoxide dismutase (SOD) and the content of malondialdehyde (MDA) in the ratos brain tissue were tested. RESULTS: The neurological deficit score of the LLLI group was significantly lower than that of the model group. The body weight and the activity of SOD of the rats decreased slightly, and the content of MDA decreased significantly after the treatment. CONCLUSION: The low-level laser irradiation on acupuncture points combined with iontophoresis can prevent focal cerebral ischemia-reperfusion injury. One of its mechanisms may be increasing the activity of SOD and decreasing the damage of the oxidation products to the body.
