Objective To observe the curative effect of surgical treatment for eyelid basal cell carcinoma. Design Retrospective case series. Participants 33 cases with eyelid basal cell carcinoma. Methods 33 cases with eyelid basal cell carcinoma treated with surgery, standard excision in 17 case and Mohs micro excision in 16 cases were analyzed, postoperative appearance and function of re- eonstruetiiv eyelid, reeurence rate and survival rate were observed by follow-up survey. Main Outcome Measures Postoperative ap- pearance, function of reconstruetiiv eyelid, recurence rate and survival rate. Results After 6 month ~ 5 years follow-up survey with an average of 2.5 years, 28 of 29 cases obtained normal eyelid appearance, 1 case with lower eyelid gentle ectropium. 11 cases showed hy- perpigmentation in skin-grafting area in early stage, and became normal in half a year. Eyelid function of 29 cases were normal. Tumour relapse was seen in one case 2 years after standard resection,the cure rate was 94.12%. No tumor relapse was seen in group of mohs micro resection, the cure rate was 100%. Within five years postoperation, there was no death case caused by basal cell carcinoma re- lapse, except one dying from myocardial infarction and another dying of eerebrovaseular disease. Conclusions Operational excision is an effective approach for eyelid basal cell carcinoma. The effect of mohs micro resection is better than the one of standard resection. With dissociate skin grafting, fluctuate tarsal transmigration and dissociate skin grafting, eyelid appearance and function recover well.

Objective To investigate the effects of propofol on mitochondrial membrane permeability during hypoxia/reoxygenation (H/R) in rat hippocampal neurons. Methods Primary cultured hippocampal neurons of fetal rats obtained from Wistar (17-18 days of gestation) were randomly divided into 3 groups: Ⅰ control group (group C), Ⅱ H/R group and Ⅲ propofol + H/R group. Neurons were cultured in the culture medium with combined oxygen glucose deprivation for 2 h followed by reoxygenation in group Ⅱ and Ⅲ. In group Ⅲ propofol was added to the culture medium with the final concentration of 20 μ mol/L before combined oxygen glucose deprivation.Neuronal viability was detected by MTT assay and mitochondrial membrane potential (MMP) with flow cytometry at 0, 4, 8, 12 and 24 h after reoxygenation (T1-5) and the permeability of cell membrane and mitochondrial membrane was monitored at T5 using laser confocal scanning microscope. Results The neuronal viability and MMP were significantly decreased (P ＜ 0.05), while the permeability of cell membrane and mitochondrial membrane was increased at T5 in group Ⅱ as compared to group Ⅰ . The neuronal viability at T1-4 and MMP at T1-5 were significantly increased (P ＜ 0.05), while the permeability of cell membrane and mitochondrial membrane was decreased at T5 in group Ⅲ compared to group Ⅱ . Conclusion Propofol can protect rat hippocampal neurons against H/R injury through increasing MMP, improving the cell and mitochondrial membrane permeability, and increasing the neuronal viability.

Objective To compare the clinical efficacy and adverse effects of pegaspargase (PEGASP) and L-asparaginase (L-ASP) in the treatment of NK/T-cell lymphoma.Methods A retrospective analysis was conducted on the clinical data of 46 patients with NK/T-cell lymphoma in Department of Oncology of Hospital of Qingdao Commercial Staff from September 2009 to July 2015.There were 24 patients treated by PEG-ASP combined with GDP (gemcitabine + cisplatin + dexamethasone) as PEG-ASP group,and 22 patients treated by L-ASP combined with GDP as L-ASP group.The efficacy and adverse reactions were compared between the two groups.Results In the PEG-ASP group,there were 11 patients with complete remission,7 patients with partial remission,and the complete remission rate and objective response rate were 45.83％ and 75.00％.In the L-ASP group,there were 9 patients with complete remission,6 patients with partial remission,and the complete remission rate and objective response rate were 40.91％ and 68.18％.There was no significant difference between the two groups in objective response rate (x2 =0.263,P =0.608).Adverse effects such as myelosuppression (25.00％ vs.22.73％,x2 =0.033,P =0.857),coagulopathy (8.33％ vs.9.10％,x2=0.008,P =0.927),liver and renal dysfunction (8.33％ vs.18.18％,x2 =0.982,P=0.322),gastrointestinal reaction (41.67％ vs.40.91％,x2 =0.003,P =0.958) were similar in the PEGASP group and L-ASP group.But the risk of allergic reaction incurred by PEG-ASP was much lower than L-ASP (4.17％ vs.36.36％),with a significant difference (x2 =7.561,P =0.006).Moreover,the PEGASP group had a shorter duration of hospitalization [(10.04 ± 1.63) d] than the L-ASP group [(13.09 ± 2.76)d],with a significant difference (t=-4.612,P=0.000).Conclusion The efficacy of PEG-ASP and L-ASP in the treatment of NK/T-cell lymphoma is similar,but the rate of allergic reaction of patients treated with PEG-ASP is significantly lower,and the hospitalization time is significantly shorter,which is worthy of further clinical application.

Objective To evaluate the effects of elevated circulating free fatty acids (FFA) level on basal and glucose stimulated insulin secretion (GSIS) of islet β-cell and to explore the pathophysiological link between FFA and impaired β-cell dysfunction. Methods Male SD rats underwent infusions with normal saline (C group), intralipid+heparin (FFA group) and N-acetylcysteine+FFA (NAC group) for 2-4 days. Insulin secretion from pancreatic tissues was evaluated during intravenous glucose tolerance test and isolated pancreas perfasion test at the end of 2 and 4 days infusion. Results After 2 days infusion, the basal insulin secretion from isolated perfused pancreas was increased in FFA group [(55.5±19.4 vs 27.4±6.7) mU/L, P<0.01], but the response to 16.7 mmol/L glucose in isolated perfased pancreas was similar in FFA and C groups. The peak value during GSIS was inhibited by 4 days FFA infusion [(46.8±33.0 vs 214.7±27.4)mIU/L,P<0.05]. GSIS was also decreased in FFA group compared with C group in IVGTr. After interfered with NAC, GSIS was partly recovered [(165.4± 14.8)mIU/L, P<0.01]. Conclusion Elevated circulating FFA levels may contribute to the abnormality of pancreatic islet β-cell through oxidative stress.

OBJECTIVE: To explore the clinical characteristics, diagnosis and surgical management of tympanosclerosis. METHOD: The data of 73 patients who underwent surgery for tympanosclerosis were retrospectively analyzed with respects to the clinical characteristics, diagnosis and management. RESULT: Seventy-three patients with tympanosclerosis (involving 73 ears) , including 17 patients with sclerosis of tympanic membrane (type I), 23 patients with fixed Malleus-incus complex (type II), 8 (type III) with fixed stapes, and 25 (type IV) with extensive typannosclerosis. Sclerosis was seen most frequently in the malleus, incus and attic, followed by the tympanic membrane, incudomalleolar joint and other regions. Audiometry was performed for all the patients 1 weeks before and 1 year( the least) after operation, which were (51.70 ± 14.93)dB HL and (36.24 ± 11.58) dB HL respectively, with success rate 83% (61/73). CONCLUSION Most of the patients suffer from conductive hearing loss. Teatment of the sclerosis around stapes is a key point. Acording to the sites of lesion and hearing level, hearing structures should be reconstructed by the rules of tympanoplasty and stapes surgery.

OBJECTIVETo observe the effects of electroacupuncture (EA) at "Dazhui" (GV 14) on Wnt-β-catenin signal pathway in annulus fibrosus cells in intervertebral disc in rats with cervical spondylosis.

METHODSForty SD rats were randomized into a control group, a model group, an EA group and a medication group, 10 rats in each one. Rats in the control group were treated with sham operation, only incision on local skin; rats in the remaining groups were made into cervical spondylosis models. After model establishment, rats in the control group and model group received fixed treatment under identical condition; rats in the EA group were treated with EA at "Dazhui" (GV 14), 30 min per treatment; rats in the medication group were treated with intragastric administration of meloxicam tablets. Treatments were both given once a day, and 14 days were taken as one session; there was an interval of 2 days between two sessions, and totally two sessions were given. After the treatments, immunohistochemistry was applied to measure the expression of Wnt, glycogen synthase kinase-3β (GSK-3β) and Axin in annulus fibrosus cells; western blot was used to test the expression of P-β-catenin.

RESULTSIn the control group, there were more positive cells of Wnt, GSK-3β and Axin, which were intensively distributed, deeply colored, and strongly positive; In the model group, there were less positive cells of Wnt, GSK-3β and Axin, which were sparsely distributed and weakly positive. The expression of Wnt, GSK-3β, Axin and P-β-catenin in the model group was less than that in the control group (all P < 0.05); expression of Wnt, GSK-3β, Axin and P-β-catenin in the EA group and medication group was higher than that in the model group (all P < 0.05); expression of Wnt, GSK-3β, Axin and P-β-catenin was not significantly different between EA group and medication group (all P > 0.05).

CONCLUSIONEA could delay the degeneration of intervertebral disc, which may be related to EA inhibiting signal pathway of Wnt-β-catenin.

Objective To investigate the correlation of the middle cerebral artery stenosis (MCAS) and the mild cognitive function impairment (MCI),and the clinical efficacy of statins in patients with MCI. Methods Six hundred and thirty-six patientse,who received transcranial color doppler ultrasound (TCD)assay, were enrolled in our hospital hospitalization or outpatients. The simple mental state examination (MMSE) and clinical dementia rating scale (CDR) were used as cognitive function assessment indexes. Forty-four cases of MCI with MCAS and 58 cases of MCI with NMCAS were used as the treatment group , who received the atorvastatin 20 mg every day , 56 cases of MCI with NMCAS were used as the control group , who only received the routine and basic diseases treatment. One yearlater,we determined the changes of MMSE and CDRagain. Results We detected 124 patients with MCAS, 512 patients with NMCAS, and 44 cases of MCAS patients with MCI, the prevalence was 35.5%,114 cases of NMCAS in patients with MCI, with the prevalence of 22.3%, the prevalence between the two groups was statistically different. One year later, the patients in the treatment group, MMSE score was improved, the score of MCI of the MCAS group improved more significantly. Conclusion The middle cerebral artery stenosis correlated with the occurrence of MCI. Atorvastatin could improve cognitive function in patients with MCI, especially for MCI which was caused by middle cerebral artery stenosis.

Objective To evaluate the clinical efficacy of thoracoscopic surgery combined with chemorad-iotherapy in patients with N2 stage ⅢA non-small cell lung cancer (NSCLC). Methods 40 patients (study group) received thoracoscopic surgery and another 40 patients (control group) received traditional thoracotomy. Combination therapy with navelbine and cisplatin were postoperatively administered for four cycles and one cycle lasted for 3 weeks. 7 to 14 days after chemotherapy , sequential conformal radiotherapy were delivered. The one-year survival and two-year survival rates , duration of tatal treatment , and adverse reactions were compared between the two groups. Results In the study group, duration of total treatment time and time to postoperative chemotherapy were significantly shorter (χ2=9.45,P=0.002 andχ2=41.324, P=0.000), and the KPS score was significantly higher (χ2 = 15.118,P = 0.002). No significant differences were found between the two groups in bone marrow suppression,gastrointestinal reactions,and one- or two-year survival rate. Conclusions As compared with conventional surgery,post-thoracoscopic surgery sequential chemoradiotherapy for patients with N2 stage ⅢA NSCLC could achieve a better efficacy with less surgical trauma , shorter hospital stay , faster recovery , and shorter time to postoperative chemotherapy and total treatment duration;it is worth further researching and popularizing.

Objective:To assess the ability of axillary reverse mapping (ARM) to identify and preserve the arm lymphatics drainage as well as determine its ability to reduce lymphedema. Methods:A total of 300 breast cancer patients who underwent axillary lymph node dissection (ALND) from June 2009 to May 2011 were enrolled in this study. Methylene blue dye (2 mL to 3 mL) was injected into the ipsilateral upper inner arm along the medial intramuscular groove to map the upper extremity lymphatic drainage system prior to ALND. The blue lymphatic and lymph nodes were identified and preserved during the operation. The change in the arm circumference was the selected method of measurement. The difference in the bilateral upper arm circumference was recorded after 2 months (difference≥2 cm is defined as lymphedema). Results:The ARM was performed successfully in 195 (65%) of 300 patients. The incidence of lymphedema was significantly lower in the successfully mapped patients than in the failing mapping patients, with statistically significant difference during follow-up at 6, 12, 18, and 24 months post operation. Conclusion:The ARM technique can identify and preserve the arm lymphatics drainage and prevent upper extremity lymphedema after breast cancer axillary lymphadenectomy.
