Objective To evaluate the effect of low dose fentanyl on target plasma concentration (CP) of propofol (P) given by target controlled infusion (TCI) required to prevent response to proseal laryngeal mask insertion in 50% of patients (EC50). Methods Forty-six ASA Ⅰor Ⅱ patients aged 20-50 yr with body mass index ≤ 30 kg/m2 undergoing elective gynecological laparoscopy were randomly divided into 2 groups (n=23each):propofol group (P) and propofol-fentanyl group (PF). Anesthesia was induced with TCI of propofol. The initial Cp of propofol TCI was set at 2.5 μg/ml in group PF and 4 μg/ml in group P. Following equilibration between plasma and effect site concentration of propofol, fentanyl 1 μg/kg (in group PF) or normal saline (in group P) was injected iv. Laryngeal mask airway (LMA) was inserted at 3.5 min after fentanyl administration. EC50 was determined by up-and-down sequential trial. The ratio of Cp between the two consecutive patients was 1.2 in group P and 1.1 in group PF. LMA insertion response was defined as nausea, bucking and/or body movement during insertion. "Probit method was used to calculate the Echo and 95 % confidence interval required to prevent LMA insertion response. Results The EC50 and 95 % confidence interval of propofol given by TCI required to prevent LMA insertion response was 4.68 (4.20-5.21)μg/ml in group P and 2.63 (2.45-2.83) μg/ml in group PF. There was significant difference between the 2 groups. Conclusion Fentanyl 1 μg/kg iv can significantly reduce the Cp of propofol TCI required to prevent LMA insertion response.

Objective To investigate the effect of 3‐dimensonal conformal radiotherapy (3D‐CRT ) combined with dendritic cell‐cytokine induced kill (DC‐CIK) cell in the treatment of recurrent small cell lung carcinoma (SCLC) in high altitude regions ,and its influence on VEGF and NSE .Methods Eighty‐five patients with recurrent SCLC in the tumor radiotherapy department of the Qinghai Provincial Fifth People′s Hospital from May 2012 to April 2014 were selected and divided into the control group(41 cases) and observation group(44 cases) according to the random number table .The two groups were respectively treated by 3D‐CRT treat‐ment and 3D‐CRT combined with DC‐CIK treatment cell .The curative effect ,incidence rate of adverse reactions ,levels of VEGF and NSE ,changes of liver and renal function indexes in the two groups were compared before and after treatment .Results The ef‐fective rate and sickness control rate of the observation group were 65 .9% and 79 .5% respectively ,which were higher than those in the control group ,and the differences were statistically significant (P<0 .05) .The levels of serum EGF and NSE ,and pain score at 4 ,8 weeks after treatment were decreased ,the differences were statistically significant (P<0 .05) .The levels of VEGF and NSE , and pain score at 8 weeks after treatment in the observation group were lower than those in the control group ,the differences were statistically significant(P<0 .05) .The incidence rate of adverse reactions in the two groups had no statistically significant differ‐ences after treatment(P>0 .05) .The levels of liver and renal function indexes had no statistically significant differences between before and after treatment(P>0 .05) .Conclusion 3D‐CRT combined with DC‐CIK cell in the treatment of recurrent SCLC in high altitude regions has more obvious curative effect ,moreover has no obvious influence on radiotherapeutic adverse reactions ,and liver and renal functions .

Age-related macular degeneration (AMD) and cataract are the most common causes of low vision worldwide.Nowadays, there is still a controversy about whether cataract surgery should be taken in patients combined with AMD and when should the surgery be taken.The aim of this review is to assess the influence of cataract surgery on the occurrence and development of AMD, to analyze the risk factors, to explore the occasion of cataract surgery in patients with AMD, and joint with anti-vascular endothelial growth factor (VEGF) treatment, also including the development and application of intraocular lens.It helps to avoid and postpone the development and progression of macular degeneration after cataract surgery and get good visual outcome.

Objective To investigate the effect of flavopiridol on the proliferation,invasiveness and apoptosis of human prostate cancer cell line LNCaP,and to explore the possibility of its application in clinical treatment.Methods MTT assay was used to detect cell proliferation,cell invasion in vitro was detected by Transwell assay,and flow cytometer was used to observe apoptosis.Results Flavopiridol inhibited the growth of LNCaP cells in a concentration-dependent and time-dependent way (P < 0.05),and reduced the ability of invasion capacity.After treated by 10 nmol/L flavopiridol for 24 h,the apoptosis rate was increased significantly to (7.5±0.9) % compared with the control group [(5.3±0.5) %] (P < 0.05).Conclusion Flavopiridol can inhibit proliferation of LNCaP cells and induce apoptosis,which may be applicable for the treatment of prostate cancer.

OBJECTIVETo investigate the causes and managements of postoperative neurological complications in pedicle screw internal fixation for the treatment of degenerative scoliosis (DS).
METHODSThe data of 325 patients with degenerative scoliosis underwent pedicle screw internal fixation was retrospectively analyzed from February 2000 to April 2013. There were 22 patients with postoperative neurological complications. Of them, 16 cases complicated with numbness or pain of lower limb and 6 cases with obvious sensation and motor function decreasing in lower limb. The patients were treated with trophic nerve, dehydration, glucocorticoids, reoperation according to the causes of disease. Postoperative at 3, 6 months and 1 year later, according to VAS scoring and muscule power improvement,the recovery of nerve injury was assessed.
RESULTSPostoperative at 3,6 months and 1 year later,VAS scoring of 16 patients with slightly nerve injury was 2.81 +/- 0.66, 1.94 +/- 0.77, 0.63 +/- 0.62, respectively, and the symptoms had obviously improved than 1 week after operation (P < 0.05). Postoperative at 3 months, among 6 patients with severe nerve injury,muscule power improved in 2 cases and no-improved in 4 cases, with VAS scoring of 4.83 +/- 1.17; postoperative at 6 months,muscule power still had not improved in 3 cases,with VAS scoring of 4.17 +/- 0.75; both of the VAS scoring had not significant difference than 1 week after operation (P > 0.05). One year later, there was no muscule power improvement in 2 cases,with VAS scoring of 3.00 +/- 1.26, there was significant difference than 1 week after operation (P < 0.05).
CONCLUSIONThe causes of postoperative neurological complication in internal fixation for the treatment of dengenerative scoliosis includes: dragging and torsion injury of spinal marrow and nerve root because of excessive orthopedic of scoliosis; inderect injury of nerve root because of malposition of pedicle screw; nerve functional impairment caused by spinal cord ischemia. Avoiding the above factors could decrease the complication and early discovery and treatment could decrease the adverse outcomes.

OBJECTIVE:To evaluate therapeutic efficacy and ADR of amphotericin B in the treatment of AIDS combined with fungal infections retrospectively. METHODS:The cases of amphotericin B in the treatment of AIDS combined with fungal in-fections were collected our hospital. Total therapeutic efficacy,distribution of pathogenic bacteria,clearance rate and ADR were evaluated. RESULTS:89 patients were involved totally,among which 45 cases were marked effect,32 cases improved and 12 cas-es failed,with effective rate of 86.5%. The fungus were found or cultured in 76 cases,among which 64 strains were cleared,but 12 strains were not,with total clearance rate of 84.2%. There were 41 ADR cases(46.1%),while all completed the treatment ex-cept 2 developing severe renal failure(2.2%). CONCLUSIONS:Domestic amphotericin B could effectively treat AIDS complicat-ing with fungal infections,and the ADRs were acceptable.
