Objective To investigate the relationship between vitamin D deficiency and diabetic peripheral neuropathy (DPN) and the risk factors of DPN. Methods From April 2016 to may 2017,the clinical data of 62 patients with T2DM diagnosed and treated in Hebei Provincial Corps Hospital of armed police were analyzed retrospectively. Among them,31 patients with DPN ( DPN group), 31 patients with T2DM ( T2DM group),and 31 healthy subjects were selected as the control group. The basic data,blood lipid,blood glucose,liver and kidney function indexes,blood calcium,blood phosphorus,25 hydroxyvitamin d [25-(OH) D] level and vitamin D deficiency rate of the three groups were compared. The risk factors of DPN were analyzed by logistic regression model. Results The body mass index, waist-hip ratio, fasting blood glucose,insulin resistance index,glycosylated hemoglobin and blood calcium levels in T2DM group and DPN group were higher than those in healthy control group,and the body mass index,waist-hip ratio,course of diabetes mellitus and glycosylated hemoglobin levels in DPN group were higher than those in T2DM group, the differences were statistically significant (all P＜0. 05) . The serum concentration of 25 ( OH) d in DPN group and T2DM group was (11± 3) μg／L and ( 17± 3) μg／L,respectively,which were lower than that in healthy control group (29± 5) μg／L,and DPN group was lower than that in T2DM group. The difference between the three groups was statistically significant (F＝5. 969,P＜0. 001). The rate of vitamin D deficiency in DPN group and T2DM group was higher than that in healthy control group (54. 8%(17／31),35. 5%(11／31) vs. 19. 4%(6／31)),which was higher than that in T2DM group,the difference was statistically significant( χ2 ＝ 2. 207, P＜0. 05) . Multivariate logistic regression analysis showed that BMI, vitamin D deficiency and course of disease over 10 years were independent risk factors for diabetic peripheral neuropathy (OR＝3. 564,11. 023,4. 158,95% confidence interval: 1. 923－6. 411,5. 988－26. 204,2. 619－6. 937,all P＜0. 001) . Conclusion Vitamin D deficiency is serious in DPN patients. BMI, vitamin D deficiency and course of disease over 10 years are independent risk factors for DPN.

Objective To study the feasibility of artificial immune system(AIS)in assistant designing of computer for new Chinese herbal compounds with anti-infectious function.Methods A group of Chinese herbal drug compounds from Treatise on Exogenous Febrile and Miscellaneous Diseases were selected as training samples.Serum was obtained from mice which were infected by Staphylococcus aureus and ig administrated with the various Chinese herbal compounds.The inhibition ability against S.aureus of the serum was tested and input into an artificial neural network(ANN)together with the characters of the every Chinese herb included in those compounds.The ANN was optimized using AIS so that it can predict the inhibitory ability against S.aureus of the Chinese herbal compounds according to the characters of Chinese herbs included in those compounds.After that the computer generated a number of Chinese herbal compounds randomly,calculated their inhibitory ability against S.aureus and output those among the top levels,so as to verify whether the predictions were correct or not.Results After verification,the Chinese herbal drug compounds designed by computer could significantly raise the serum's inhibitory ability against S.aureus.Conclusion The computer can be an assistant for designing new Chinese herbal compounds with anti-infectious function

Objective To investigate the distribution of androgen receptor (AR) gene CAGrepeats in the Chinese Han nationality and its application in genetic diagnosis for Kennedy's disease (KD). MethodsRT-PCR,denaturing polyacrylamide gel electrophoresis (DPAGE) and gene sequencing were conducted for AR gene CAG repetition among 100 healthy controls and 28 patients diagnosed as motorneuron diseases,and the number of the repetition was counted. Results The healthy controls had a range of 15-31 times of CAG repetition,with an average of (23 ± 3) times.Among patients with motoneuron disease,3 cases with CAG repetition for more than 40 times (namely,46,47 and 47 times) were diagnosed as KD.The main clinical manifestations included slow progress of limb weakness,primarily in the proximal lower limbs,fatigue accompanied by myalgia,muscle jumping,muscle atrophy,elevated serum creatine kinase (CK) levels,neurogenic damage revealed by electromyogram (EMG) and androgen insensitivity.Conclusions The incidence of KDmay be underestimated in the Chinese population.Performing genetic diagnosis in patients with motor neuron disease for AR gene can improve clinical diagnosis and avoid misdiagnosis.

Objective:To investigate the clinical efficacy of low-energy laser in the treatment of erosive oral lichen planus (OLP) and its effect on patients' pain.Methods:Eighty-six patients with erosive OLP who were treated in Shanxian Central Hospital from February 2018 to January 2020 were included in this study. They were randomly divided into control and observation groups ( n = 43/group). The control group was treated by local injection of dexamethasone, and the observation group was treated with semiconductor low-energy laser irradiation. All patients were treated for 8 weeks. Pain scores and physical sign score before and after treatment were evaluated in each group. Therapeutic effects were compared between the two groups. Area of lesion was measured in each group. Recurrence of erosive OLP was calculated at 3 and 6 months after surgery. Results:Before treatment, there were no significant differences in visual analogue scale (VAS) score and physical sign score between the two groups (both P > 0.05). At 7, 14, 28 and 56 days after treatment, VAS score and physical sign score were significantly decreased in each group compared with those before treatment, and VAS score and physical sign score in the observation group were significantly lower than those in the control group (all P < 0.05). Total response rate in the observation group was significantly higher than that in the control group [93.02% (40/43) vs. 83.72% (36/43), χ2 = 1.81, P > 0.05). Before and 1 month after treatment, there was no significant difference in area of lesion between control and observation groups (both P > 0.05). At 3 and 6 months after surgery, area of lesion in the observation group was (0.31 ± 0.14) cm 2 and (0.32 ± 0.12) cm 2, respectively, which were significantly smaller than those in the control group [(0.42 ± 0.18) cm 2, (0.48 ± 0.19) cm 2, t = 3.16, 4.67, both P < 0.05). At 3 and 6 months after treatment, recurrence of erosive OLP in the observation group was 2.33% (1/43) and 13.95% (6/43), respectively, which were significantly lower than those in the control group [13.95% (6/43), 37.21% (16/43), χ2 = 3.89, 6.11, both P < 0.05]. Conclusion:There is no significant difference in the short-term efficacy of low-energy laser versus conventional corticosteroids in the treatment of erosive OLP. However, low-energy laser has a more obvious short-term pain relief effect than conventional corticosteroids. It can accelerate the healing of injured tissue and decrease the recurrence rate of erosive OLP.
