Objective To study the roles of the contact heat evoked potential (CHEP) in evaluating the small nerve fibers of cranial and spinal in elderly diabetic patients,and to analyze the feature of the small fibers in order to provide scientific foundations for early diagnosis of diabetic neuropathy (DN).Methods Totally 50 diabetic patients and 40 healthy subjects were included in this study.The diabetic patients were divided into the normal nerve conduction group (n=17) and the abnormal nerve conduction group (n=33).CHEP was determined and thermal stimuli was given to the area of eyelid,forearm and peroneal.Sensory and motor nerve conduction velocity in the upper and lower limbs were tested in all diabetic patients.Results Compared with the healthy group,the N wave latencies were prolonged and the N-P amplitudes were reduced in the area of eyelid,forearm and peroneal in diabetic patients (all P＜0.01).Compared with the healthy group,the logarithm of N-P amplitudes were reduced in areas of forearm and peroneal [(1.70±0.10) vs.(1.60±0.14),(1.65±0.078) vs.(1.54±0.15),both P＜0.05] and N wave latencies were prolonged in eyelid area [(343.1±18.2) ms vs.(385.4±26.5) ms,P＜0.05] in normal nerve conduction group.Compared to group with normal nerve conduction velocity,the logarithm of N-P amplitudes was reduced in peroneal area [(1.54±0.15) vs.(1.44±0.15),P＜0.05] in abnormal nerve conduction group.Conclusions CHEP can detect the early impairment of the small fibers in elderly diabetic patients.The early smallfiber impairments in diabetic neuropathy may be axon-oriented in spinal nerves and myelin-oriented in cranial nerves.

BACKGROUND:Monofocal and multifocal Toric intraocular lens that have been widely used in clinic exhibit xcelent biological and optical characteristics and have good safety and stability after implantation. OBJECTIVE:To compare the outcomes and rotation stability in patients with cataract and astigmatism after implantation of monofocal and multifocal intraocular lens. METHODS:A total of 210 patients with cataract and astigmatism who received phacoemulsification and intraocular lens implantation were included in this study. Of them, 105 patients were assigned to monofocal intraocular lens implantation and the other 105 patients to multifocal intraocular lens implantation. Uncorrected visual acuity, best corrected visual acuity, residual astigmatism were reexamined at 1, 3 weeks and 1 month after surgery. The rotation of Toric intraocular lens was determined. The incidence of complications and spectacles- independent rate were recorded. RESULTS AND CONCLUSION:Visual acuity and residual astigmatism in each group were significantly improved after 1 week of intraocular lens implantation (P < 0.05); furthermore, these two indicators became better over time. Improvement of visual acuity and residual astigmatism in multifocal intraocular lens group was more obvious than that in monofocal intraocular lens group. Postoperative intraocular lens rotation at < 5° occurred in both groups. The intraocular lens rotation degree in multifocal intraocular lens group was higher than that in monofocal intraocular lens group at different time points (P < 0.05). There were no significant differences in incidence of complications and spectacles-independent rates between two groups at 1 month after surgery. These results demonstrate that multifocal Toric intraocular lens provides better visual acuity and residual astigmatism improvement, while monofocal Toric intraocular lens provides better rotation stability.

Objective To study the clinical effect of personalized intervention on elderly patients with colostomy after Miles operation for rectal carcinoma. Methods 114 cases elderly patients with colonic stoma after Miles operation for rectal cancer from June 2014 to January 2016 were divided into control group and observation group by random number method, 57 cases in each. The control group were treated with routine intervention, while patients in observation group was treated with personalized intervention. the self-care ability score before intervention, the incidence of complications, intervention satisfaction and life quality score were compared between the two groups at the same time. Results The total complication rate in the observation group was significantly lower than that in control group ( 5.25% vs 22.80%) (χ2 = 8.36, P = 0.000); the intervention satisfaction of the observation group was significantly higher than that in control group (91.23% vs 75.44%) (χ2 = 6.60, P = 0.010). After intervention, the self-care ability score and life quality score of observation group were significantly higher than that in control group (P < 0.01). Conclusion The personalized intervention can reduce the complications, significantly improve the patients' life quality score and self-care ability, and effectively alleviate the negative situation, improve the patients intervention satisfaction, with a higher development value, it is worth of clinical promoting.

Clinically, kidney?yang deficiency is one of the main TCM syndromes in patients with major depressive disorder. Warming yang and reinforcing kidney as a therapeutic measure for the treatment of depressive disorder has a?chieved good clinical curative effect. However, there are some problems on the study of kidney?yang deficiency depression. One of the reasons is that the establishment methods of depression animal model with kidney?yang deficiency are not uni?fied. In order to provide reference and further improve the replication method of depression animal models with kidney?yang deficiency, we systematically collected and analyzed the experiment results published in the past 15 years about the depres?sion animal model with kidney?yang deficiency induced by glucocorticoid hormone drugs and find out their similarities and differences.

Objective To observe the effect of stump ulcer repairing in people affected by leprosy (PALs). Methods Bone shortening and osteophyte removal were performed in 73 PALs amputees with stump ulcers. Results All the incisions were healed without any delay. During a follow-up period of 3～12 years, no relapse or new ulcers were found in 70 PALs. 3 PALs developed new ulcers, which were healed after debridement, resting, and prosthesis repairing. Conclusion Surgical revision of the bone in amputation stump can change the local distribution of pressure. Postoperative self-care teaching to the PALs and their sustaining daily self-care will finally prevent them from stump ulcer recurring.

Objective To estimate the effect of the enviromental pollutant 2,3,7,8-tetrachlorodibenzo-pdioxin (TCDD),a representative of the dioxin family,on the expression of cytochrome P4501A1 (CYP1A1) in cultured human immortalized SZ95 sebocytes in vitro,so as to improve understanding of the pathogenesis of chloracne.Methods SZ95 sebocytes were cultured with or without the presence of 10 nmol/L TCDD for two hours or three days.Real time fluorescence-based PCR was performed to quantify the mRNA expression of CYP1A1,immunohistochemistry and Western blot to determine the expression level of CYP1A1 protein,in the SZ95 cells.Chi-square test was done to compare the protein and mRNA expressions of CYP1A1 between untreated and treated SZ95 cells.Results Real time PCR showed that the mRNA expression of CYP1A1 was low in SZ95 sebocytes,and increased by 5.622 times after 2-hour treatment with TCDD(P ＜ 0.05).Immunohistochemistry revealed a weak expression of CYP1A1 protein in the cytoplasm and nuclei of untreated SZ95 sebocytes,which was also significantly enhanced by the TCDD treatment.Western blot results showed that the relative expression level of CYP1A1 protein was 4.233 ± 0.252 in SZ95 sebocytes treated by TCDD for three days,significantly higher than that in untreated sebocytes(0.123 ± 0.208,P ＜ 0.05).Conclusions There is a low expression of CYP1A1 mRNA and protein in SZ95 sebocytes,which can be upregulated by TCDD,suggesting that the CYP1A1 gene is a downstream target of the aryl hydrocarbon receptor responsible for the abnormal differentiation of human sebocytes.
