BackgroundWith the number of diabetics increases,people pay more attention to the diabetic keratopathy.The major mechanism leading to diabetic keratopathy is diabetic corneal neuropathy.So it is significant to observe pathologic mechanism of diabetic corneal neuropathy. Objective To investigate the protective effects of edaravone( a free radical scavenger) on corneal nerve of rats with experimental diabetic corneal neuropathy,then explain the effects of oxidative stress in the pathologic mechanism of diabetic corneal neuropathy. Methods Seventy Sprague-Daxley male rats were taken as experimental subjects and 20 of them were used as normal control group.The remaining 50 were induced to be diabetic mellitus by a single intraperitoneal injection of streptozotocin and divided into 2 groups randomly:edaravone treated group and diabetic control group.In the edaravone treated group,edaravone(0.2 g/L) eye drops were used 3 times a day until the animal was killed.Five rats in each group were sacrificed at 6,8,10 and 12 weeks respectively.Then the corneal sensation,number of corneal nerve fibers,morphology,content of malondialdehyde(MDA) and activity of superoxide dismutase(SOD) in the corneal tissue were detected.ResultsIn the diabetic control group,the corneal sensation and the number of corneal nerve fibers were decreased,the density of neural network for cluster was sparse,the nerve activity was decreased,the content of MDA in the corneal tissue was significantly increased,the activity of SOD in the corneal tissue was significantly decreased (P＜0.01 ).Accompany with the course of disease,the above change was obvious day after day.Compared with the diabetic control group,the corneal sensation and the morphological abnormalities in corneal nerve of edaravone group were improved significantly which had the partial branches to the 12th week,the content of MDA in the corneal tissue was significantly decreased,the activity of SOD in the corneal tissue was significantly increased (P＜0.01).Conclusions Edaravone can lower diabetic corneal nerve of rats with experimental diabetic corneal neuropathyinjury,Oxidative stress may be a critical pathologic mechanism of diabetic corneal neuropathy.

Objective:To study the expression of IFN-γ,IL-4 and IL-17 in peripheral blood of patients with oral lichen planus(OLP). Methods:The level of IFN-γ,IL-4 and IL-17 in peripheral blood were detected by ELISA in 60 OLP patients(including 30 erosive ca-ses and 30 non-erosive cases)and 25 healthy volunteers(controls).Data were statistically analyzed by SPSS 13.0.Results:(1 )The level of IFN-γin serum of patients with non-erosive OLP and erosive OLP were significantly lower than that in the controls(P<0.01);while the level of IL-4 in the patients were significantly higher than that in the controls(P<0.01),and the IFN-γ/IL-4 ratio in non-ero-sive OLP and erosive groups were significantly lower than that in the control group(P<0.01);(2)The level of IL-17 in erosive OLP pa-tients was significantly higher than that in the controls(P<0.05),while no statistical difference was seen between non-erosive OLP group and the control group(P>0.05).Conclusion:The down-regulated level of IFN-γand up-regulated level of IL-4,which result in the decrease of IFN-γ/IL-4 ratio,might be one of the immune etiological factors of OLP,while the up-regulated level of IL-17 protein in OLP may be mainly related with the inflammatory processes of OLP.

Objective To investigate the effects of serum from patients receiving isoflurane and sevoflurane on the invasion and migration ability of human lung adenocarcinoma cell line A549. Methods Twenty ASAⅠorⅡ lung cancer patients aged 40 ~ 68 yr undergoing radical surgery were randomly divided into sevoflurane group (SEV group, n = 10) and isoflurane group (ISO group, n = 10). The concentration of sevoflurane or isoflurane maintained 1.5 MAC during anesthesia. Ten healthy volunteers were selected as control group. Serum was separated from blood sample taken at the end of surgery. A549 cells were randomly divided into sevoflurane group (group SEV, n = 10), isoflurane group (group ISO, n = 10) and control group (group C, n = 10). Cells of SEV group and ISO group were treated with 10% serum as respect to anesthetics for 24 hours. Cells of group C were treated with serum of control group. The invasion ability of cells was evaluated by Transwell assay. The migration ability of cells was determined by wound healing assay. The expressions of MMP-2 and MMP-9 in A549 cells were detected by ELISA. Results Compared with group C and ISO group,the number of invasive cells in group SEV was reduced significantly (P < 0.05). The levels of MMP-2 and MMP-9 in group SEV were significantly decreased compared with those of group C and ISO group (P<0.05). Conclusion The serum of patients receiving sevoflurane anesthesia can attenuate the metastatic ability of A549 cells through inhibiting the expression of MMP-2 and MMP-9.

Objective To evaluate the diagnostic value of in vivo 1H-MRS in the hyper acute reaction stage of radiation-induced brain injury after nasopharyngeal carcinoma radiotherapy. Methods Eighteen patients with nasopharyngeal carcinoma accepted radiotherapy for the first time. Bilateral temporal lobes in all cases were examined by conventional MRI and 1H-MRS before and after radiotherapy with radiation dose of 20 Gy, 40 Gy, and 60 Gy, respectively. MR image was performed with T_1-weighted gradient- and spin-echo, T_2-weighted spin-echo, fluid-attenuated inversion-recovery, and point resolution spectroscopy. The change of the spectroscopic morphology and the ratios of the metabolites were observed. Results There were no changes of signal in the temporal lobes with conventional MRI, but the peak height of NAA and Cho decreased obviously in the anterior half of the temporal lobes with 1H-MRS after radiotherapy. The post-radiotherapy changes of different metabolic peak in the anterior temporal lobes presented as two types: one type was that Cho and NAA peak were of the same height simultaneously. There were 20 locations (56%) of the 36 reaching the peak when accepting 20 Gy, 22 (61%) when accepting 40 Gy, and 13 (36%) when accepting 60 Gy, respectively. The other type was that Cho peak became the highest, whereas NAA peak was obviously lower and decreased to be the second highest. There were 4 locations(11%) of the 36 reaching the peak when accepting 20 Gy, 10 (28%) when accepting 40 Gy, and 23 (64%) when accepting 60 Gy, respectively. The ratio of Cho/Cr, NAA/Cr, and NAA/Cho decreased in the same position too. In addition, there was positive correlation between the ratios of the metabolites and the dose of radiotherapy.Conclusion 1H-MRS can be used to diagnose the radiation-induced injury of the brain in early acute reaction stage after nasopharyngeal carcinoma radiotherapy through reflecting histiocytic metabolism, and provide objective basis for pathology development and cellular metabolism study, also it can provide feasible projects for the clinic.

Objective To compare the anthelmintic effect of albendazole with that of triclabendazole against Fasciola giganti-ca. Methods Two patients infected with Fasciola gigantica were investigated,and one was administered with albendazole orally (200 mg,twice per day for 5 days)and another was administered with triclabendazole[10 mg/(kg?d)for 2 days]. Their total fe-ces were collected daily during the period of whole therapy,and the eggs of the parasite were collected by using the nylon bag method,and incubated at 28℃. Results The parasite eggs were detected from the first patient’s dejecta on the 1st,2nd and 5th day after the end of the treatment,and no miracidiums hatched out as well as no eggs developed during the period of 25 days of the incubation. Meanwhile,her body temperature fluctuated between 37.4℃and 38.3℃,and she still complained bellyache. For the other invalid,the eggs were not detected on the 2nd and 5th day after the end of the treatment. However,the eggs before and dur-ing the treatment developed the miracidiums of Fasciola gigantica on the 13th day after the incubation,but the eggs collected from the 1st day after the termination of the therapy did not develop and no miracidiums hatched out. At the same time,the signs and symptoms of the patient vanished after the 4th day of the end of the therapy. Conclusions Albendazole has no obvious insecticid-al activity on adult Fasciola gigantica in the short term,but may affect the development of eggs. Triclabendazole has the anthelmin-tic effect on the adults as well as eggs of Fasciola gigantica. In addition,triclabendazole has the characteristics of well curative ef-fect,short course of treatment,and no obvious side effects.

Diabetic gastroparesis (DGP) is one of the most common complications of diabetes. Acupuncture is an ef-fective treatment for DGP in recent years. Literatures on acupuncture therapy for DGP treatment were screened for the past 10 years. Statistical analysis was made on acupoints used in the literatures in order to find the most com-monly used acupoints and combinations. This article was aimed to explore and summarize the use of the acupuncture law for the better service of clinical practice.
