Objective To evaluate the effect of dexmedetomidine alternative to propofol administered in general anesthesia on maintainance and recovery in patients undergoing gynecologic laparoscopy.Methods One hundred and twenty patients undergoing gynecologic laparoscopy,were divided into group C,D1 and D2 with 40 cases each by random digits table method.Group C received propofol 100 μ g / (kg min) and remifentanil 0.10-0.25 μ g / (kg min) intravenous infusion,group D1 received propofol 100 μ g/(kg min),remifentanil 0.10-0.25 μ g/(kg min) and dexmedetomidine 0.2 μ g/(kg h) intravenous infusion,while group D2 received dexmedetomidine 2.0-3.0 μ g / (kg h) and remifentanil 0.10-0.25 μ g/ (kg min).Cis-atracurium was given on time to maintainance of anesthesia.The heart rate (HR),mean arterial pressure (MAP) were recorded at the following time points:arriving at operating room (To),anesthesia induction (T1),intubation (T2),skin incision (T3),pneumoperitoneum (T4),10 min after pneumoperitoneum (T5),20 min after pneumoperitoneum (T6),the end of operation (T7),discharge from post anesthesia care unit(T8) and the first postoperative day (T9).The time of emergence,extubation and duration in post anesthesia care unit were recorded too.Ramsay scale and Riker Sedation-Agitation Scale on emergence,extubation and discharge from post anesthesia care unit and post anesthesia recovery score at T9 were also recorded.Results The MAP in group D2 was higher at T3 to T7 time-points than that in group C and group D1 [(93 ± 10),(99 ± 11),(94 ± 13),(95 ± 10),(91 ± 10) mm Hg (1 mm Hg =0.133 kPa) vs.(88± 11),(90± 10),(87±9),(86±9),(83±8)mmHgand (87±9),(90± 10),(86±8),(85 ±7),(83 ± 7) mm Hg],there were significant difference (P ＜ 0.05).There were no significant difference among groups on the HR at each time point and the time of emergence,extubation and duration in post anesthesia care unit (P ＞ 0.05).Ramsay scale was lower on emergence and Riker Sedation-Agitation Scale was higher on emergence and extubation in group C than that in group D1 and group D2 [(3.7 ± 1.3) scores vs.(4.0 ± 0.9),(4.2 ±0.9) scores,(3.1 ± 1.0) scores vs.(2.8 ±0.6),(2.7 ±0.9) scores,(3.3 ±0.7) scores vs.(3.2 ± 0.4),(3.0 ± 0.5) scores],there were significant differences (P ＜ 0.05).Riker Sedation-Agitation Scale was higher on extubation in group D1 than that in group D2(P ＜ 0.05).Post anesthesia recovery score at T9 in group D2 was apparently increased compared with that in group C and group D1 [(108 ± 10) scores vs.(93 ± 13),(93 ± 15) scores] (P ＜ 0.05).Conclusions Dexmedetomidine 2.0-3.0 μ g/ (kg h) administered in general anesthesia on maintainance in gynecologic laparoscopy can improve the quality of extubation and promote postoperative recovery without prolonging extubation time,but have a influence on hemodynamic changes at early stage of pneumoperitoneum.

Objective To investigate the changes of plasma IL-6 and IL-8 level and the inhibitory effects of preoperative administraction of bile salt or anti-endotoxin antibody against endotoxin in cases of obstructuve jaundice.Methods 50 cases with obstructive jaundice were randomized into OJT1 group taking bile salt orally,OJT2 group receiving intravenous anti-endotoxin antibody and OJ group receiving general treatment.The plasma levels of endotoxin(ET),interleukin-6(IL-6) and interleukin-8(IL-8) were determined in all the cases.Results The plasma ET level was significantly lower in the patients of OJT1 and OJT2 groups than in those of OJ group preoperatively and was further decreased postoperatively(P

Cancer/testis(CT) antigens,of which more than 40 kinds have now been identified,are encoded by genes that are expressed normally in the human germ line,and are also expressed in various tumor types,including melanoma,and carcinomas of the bladder,lung and liver.These immunogenic proteins are being vigorously pursued as targets for therapeutic cancer vaccines.In this paper,the classification,expression and function of CT antigens are reviewed.

Objective To observe the changes of mechanical pain thresholds and autophagy related proteins microtubule-associated protein 1 light chain 3 (LC3) and sequestosome 1 (SQSTM1 also known as p62) expression levels in the C57BL/6 mouse models of chronic prostatitis/ chronic pelvic pain syndrome (CP/CPPS),and provide animal experimental evidence for CP/CPPS pain and autophagy study.Methods 36 male C57BL/6 mice were randomly divided into three groups: the model group,control group and na(i)ve group.The CP/CPPS model was established by subcutaneous injection in the lower abdomen region with suspension liquid,containing protein extract of male SD rat prostate gland and complete Freund adjuvant.At 1month and 6 months after modeling,the mice were sacrificed and prostate tissues were harvested for histological examination using HE staining.Mechanical tactile hyperalgesia was measured with von Frey filaments.The autophagy-related proteins LC3 and p62 expression levels were detected by immunohistochemistry,respectively.The average IOD was measured by Image Pro Plus 6.0,and the statistical analysis was performed with GraphPad Prism 5 software.Results The histopathology showed the appearance of chronic prostatitis in the model group,representing hyperplasia and lymphocytic infiltration to a different degree and lasted for 6 months after modeling.Moreover,prostate intraepithelial neoplasia (PIN) appeared in the model group at 6 months after modeling,characterized by the disappearence of basement membrane and obvious nuclear abnormality,while the control and na(i)ve groups showed normal histology during the 1-6 months.Compared with the control and na(i)ve groups,the mechanical pain threshold in the model group was significantly decreased along with the time from (0.353±0.154) g at 0 week to (0.008±0.00) g at 22 weeks (P<0.05).The average IOD of LC3 and p62 expression in the model group was significantly increased with timing from [(2.767±0.464)%,(2.872±1.642)%] at 1month to [(13.501±1.900)%,(9.07±0.49)%] at 6 month,P<0.05.Conclusions A CP/CPPS model is successfully established in C57BL/6 mice.For the model group,the mechanical pain threshold is decreased and autophagy levels are increased gradually with time.These phenomena show that chronic inflammation microenvironment may promote pain and autophagy activity in the prostate,which is closely related with the occurrence and development of prostatic intraepithelial neoplasia.

BACKGROUND: Telomerase can maintain the telomere length and avoid cel replicative senescence and apoptosis in somatic cells. Its catalytic subunit cal ed telomerase reverse transcriptase has roles in mediating cellsurvival and anti-apoptotic functions. OBJECTIVE: To evaluate the effects of human telomerase reverse transcriptase on amyloid β1-40-induced human embryonic cortical neurons injury. METHODS: Human cortical neurons derived from 12-16 weeks old aborted fetuses were transfected with recombinant adenovirus vector encoding human telomerase reverse transcriptase. Expression of human telomerase reverse transcriptase was evaluated by immunocytochemical staining. Telomerase activity was measured using a PCR-based telomeric repeat amplification protocol enzyme-linked immunosorbent assay kit. Human embryonic cortical neurons were treated with 10 μmol/L ol/L amyloid β1-40 after transfected for 3 days. Cel viability, reactive oxygen species levels and glutathione contents in human embryonic cortical neurons were respectively detected by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, fluorescent probe 2',7'-dichlorodihydrofluorescein diacetate and chromatometry. RESULTS AND CONCLUSION: Expression of human telomerase reverse transcriptase reached peak at 3 days after transfection, and the telomerase activity was rebuilt; 10 μmol/L amyloid β1-40 could significantly reduce the cel viability of neurons and glutathione content (P < 0.05 and P < 0.01), and increase the reactive oxygen species levels (P < 0.05). The neurons transfected with human telomerase reverse transcriptase gene could be significantly against the toxicity of amyloid β1-40 and increase the cel viability and glutathione content (P < 0.05 and P < 0.01), and decrease the reactive oxygen species levels (P < 0.05). The results indicate that human telomerase reverse transcriptase can protect amyloid β1-40-induced human embryonic cortical neurons injury
