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.

To retrospectively analyze the clinical data of 42 patients at our department with bulbar myasthenia gravis.They underwent video-assisted thoracoscopic extended thymectomy (VATET) from May 2003 to August 2010.Another 42 patients treated with medications alone were selected as controls.Compared with the control group (4.32 ± 0.23),postoperative dysphagia scores improved significantly in patients undergoing VATET(9.21 ±0.41).And so did the dysphagia assessment classification (P ＜0.05).Thus VATET could effectively and definitely relieve dysphagia in patients with bulbar myasthenia gravis.

OBJECTIVE: To investigate and analyze the status of anxiety and depression among patients with four types of peripheral vertigo. METHOD: The clinical data of patients with one of the four types of peripheral vertigo, namely benign paroxysmal positional vertigo (BPPV), vestibular migraine (VM), Menière's disease (MD), and vestibular neuritis (VN), were collected. Thorough otological and neuro-otological examinations were performed on these patients, and their status of anxiety and depression were assessed using self-rating anxiety scale (SAS) and self-rating depression scale (SDS). RESULT: A total of 129 patients with one of the four types of peripheral vertigo(49 cases of BPPV, 37 cases of VM, 28 cases of MD and 15 cases of VN) were included in the study. The scores of SAS and SDS were higher in the patients with VM or MD than those with BPPV or VN (P < 0.05), and the incidence of anxiety (VM = 45.9% MD = 50.0%) and depression (VM = 27.0% MD = 28.6%) were higher in the patients with VM or MD than those with BPPV or VN (P < 0.05). Paired comparisons showed the differences between the incidences of BPPV and MV groups, BPPV and MD groups, and MD and VN groups were statistically significant (P < 0.05). CONCLUSION Among patients with different types of peripheral vertigo, anxiety/depression is more common in patients with VM or MD. This may be due to the different mechanisms involved in different types of vertigo, as well as differences in the prevention and self-control of the patients against the vertigo.
