Objective:To discuss the influence of mindfulness-based stress reduction plus micro-class education on the complications and knowledge mastery rate in surgical patients with diabetes mellitus.Methods:A total of 105 patients, diagnosed as diabetes mellitus complicated with appendicitis in the Affiliated Hospital of Chengde Medical College were selected from January 2019 to January 2020. They were hospitalized for laparoscopic appendectomy and were randomly divided into the control group ( n = 52) and the study group ( n = 53) in accordance with the random number table. The patients in the control group were given routine nursing care, and the patients in the study group were given mindfulness decompression therapy combined with micro-classroom education. The blood glucose control and psychological emotion of the two groups before and after operation, and the postoperative complications and the mastery rate of disease knowledge of the two groups were compared. Results:There was no significant difference in blood glucose indexes between the two groups at baseline ( P>0.05); FBG, HbA1c and other indicators in the two groups were improved during operation and 24h after operation, but FBG (7.38±0.54) mmol/L, HbA1c (6.39±0.21)% and FBG (6.90±0.52) mmol/L and HbA1c (6.10±0.39)% in the study group were lower than those in the control group [(8.16±1.21) mmol/L, (7.53±1.05)%, (7.60±0.57) mmol/L, (6.50±0.41)%], the difference was statistically significant ( t value was 6.789-13.264, P < 0.05); there was no significant difference in SAS and SDS scores between the two groups at baseline ( P > 0.05), until discharge, the SAS and SDS scores of the treatment group were 35.81±5.49 and 42.08±4.91 respectively, which were significantly lower than those of the control group (42.21±5.53, 6.51±4.72) respectively, compared with the corresponding scale scores of the control group, the difference between the two groups after treatment was statistically significant ( t value was 5.386, 4.265, P < 0.05). Compared with 17.31% (9/52) of the control group, the incidence of complications in the study group decreased to 5.66% (3/53), there was significant difference ( χ2 value was 6.789, P < 0.05). The qualified rate of disease knowledge mastery in the study group (98.11%,52/53) was significantly higher than that in the control group (86.53%, 45/52), and the difference was significant ( χ2 value was 5.062, P < 0.05). Conclusion:The mindfulness-based stress reduction plus micro-class education can effectively control the laparoscopic appendectomy patients blood glucose, stabilize the mental emotions, increase the illness knowledge mastery degree, keep in good mood, reduce the postoperative complications and promote the fast recovery.

Objective:To estimate the correlation between DR and diabetic corneal nerve damage by comparing changes of corneal sub-basal nerve plexus (SNP) in the whorl-like region in different DR stages.Methods:In this cross-sectional study, 66 eyes of 66 type 2 diabetes patients aged 50-65 years old in Shanxi Eye Hospital from September 2018 to January 2019 were included.The subjects were divided into non-diabetic retinopathy group (NDR), non-proliferative diabetic retinopathy group (NPDR) and proliferative diabetic retinopathy group (PDR) accordingly, the right eyes were enrolled.20 eyes of 20 age and gender matched age-related cataract patients were also included as control group.All the subjects underwent confocal corneal microscopy to observe the morphology of SNP in the whorl-like region and measure the nerve fiber length (NFL) in this area.Covariance analysis using disease course as the covariate was used to analyze the differences of NFL value among groups, and Spearman rank correlation analysis was used to analyze the correlation between NFL value and DR stages.The study protocol was approved by the Ethics Committee of Shanxi Eye Hospital.Written informed consent was obtained from each patient prior to entering the study cohort.Results:The whorl-like region were observed in all the eyes.In the control group, nerve fibers were uniform in thickness, densely distributed with regular course, and most of the tested eyes had intact whorl-like structure.Nerve fibers in different DR groups all showed generally decrease in diameter and density, with increase in tortuosity, accompanied by different degrees of whorl-like structure loss.Eyes in the NDR group and NPDR group mainly showed nerve structure loss in the whorl-like center; while some eyes in the PDR group also showed nerve structure loss in the inferior and temporal of the whorl-like region.The NFL values were (21.08±4.74), (16.47±6.35), (14.95±3.90), and (11.61±3.24)mm/mm 2 in the control group, the NDR group, the NPDR group, and the PDR group, respectively, the overall difference was statistically significant ( F=10.541, P<0.001). The NFL value in the control group was significantly higher than those in the different DR groups, the differences were statistically significant (all at P<0.01). Spearman rank correlation analysis showed that there was a significant negative correlation between NFL value and DR stages ( rs=-0.356, P=0.003). Conclusions:Diabetic SNP damage occurs earlier than DR, and progress gradually with the development of DR; Different stages of DR are accompanied by different degrees of nerve structure loss; The structure loss begins at the whorl-like center and gradually develops to downward and the temporal side.The ophthalmologists should take the condition of ocular surface into account when treating ocular fundus diseases of diabetic patients.

【Objective】 To explore the effect of massive blood transfusion on inflammatory factors, islet B cell function, incidence and mortality of multiple organ dysfunction syndrome (MODS) in patients with severe traumatic hemorrhage. 【Methods】 214 traumatic hemorrhage patients who received blood transfusion and were hospitalized in the Third People′s Hospital of Xingtai from January 2015 to June 2019 were enrolled and divided into the routine blood transfusion group (n=118) and massive blood transfusion group (n=96) according to the amount and method of blood transfusion. The changes of the inflammatory factors such as TNF α and IL-6, the functional indexes of Islet B cells such as HOMA-B and Δ INS30 / Δ GLU30, and the incidence and mortality of MODS in two groups 3 d after blood transfusion were observed. 【Results】 The level of TNF α(ng/L), IL-6(ng/L), HOMA-B and Δ INS30 / Δ GLU30 were (64.21±8.41) vs (30.75±5.26), (216.52±17.99) vs (152.45±16.26) (58.55±10.23) vs (103.47±17.48) and (2.95±0.69) vs (5.87±1.30) in the massive transfusion group and routine transfusion group, respectively (P<0.01). The incidence of MODS was 63.54%(61/96) vs 40.07%(52/118)(P<0.01) while the mortality of MODS was 46.88%(40/118) vs 33.90% (P>0.05). 【Conclusion】 The massive blood transfusion could increase the incidence of MODS in patients with severe traumatic hemorrhage by promoting inflammatory reaction and dysfunction of islet B cells.

In the paper, the study was reviewed on the infrared temperature characteristics of acupoints in recent 10 years. CNKI, WANFANG, VIP, SciVerse ScienceDirect and Springer databases were retrieved, with"infrared thermal imaging" and "acupoint" as the key words. The retrieving time was from January 1, 2006 to December 31, 2016. Totally, 468 relevant papers were searched and 169 papers of them were read carefully on acupoint infrared temperature. In terms of physiological condition, pathological condition and the stimulation methods such as acupuncture, moxibustion,, embedding therapy and cupping therapy, the general situation was reviewed on the infrared temperature characteristics of acupoints separately. It was found that the study on infrared temperature characteristics of acupoints in physiological condition was limited and the characteristics discovered were not enough to systematically review the physiological and physical properties of acupoints. The study in terms of the pathological condition objectively reflected the effects and rules of diseases. It was showed in the study of acupoint infrared temperature characteristics after stimulation that the changes of infrared thermal imaging tempe-rature at some specific region induced by different therapies and parameters might be used to deduce the potential mechanism and optimal parameters or schemes of intervention method and contributed to the formation and deve-lopment of quantitative diagnosis and treatment. The authors believe that the study on infrared temperature characteristics of acupoint provides the active significance in the exploration on the physiological and physical characteristics of acupoint, the effects and rules of diseases as well as the quantitative diagnosis and treatment.

Objective:To explore the damage of panretinal photocoagulation (PRP) to the subbasal nerve plexus (SNP) and its related mechanisms by comparing SNP changes in wide-field mosaic between before and after PRP treatment in diabetic patients.Methods:A randomized controlled study was conducted.Fifty-seven patients (114 eyes) with type 2 diabetes mellitus and binocular diabetic retinopathy (DR) stage IV to receive PRP treatment in Shanxi Eye Hospital from April to November 2019 were enrolled.The subjects were randomly divided into horizontal-vertical laser group and vertical-horizontal laser group according to a random number table.Twenty-nine eyes from 29 patients were assigned to the horizontal-vertical laser group with the photocoagulation sequence of temporal-nasal-inferior-superior.Twenty-eight eyes from 28 patients were assigned to the vertical-horizontal laser group with the photocoagulation sequence of inferior-superior-temporal-nasal.The severer eyes of each subject were chosen as the treatment eye and the contralateral eyes were chosen as the control eye.Corneal confocal laser scanning microscopy (CCM) was performed before PRP treatment, 1 week after each photocoagulation, and 1 month after the completion of PRP treatment to collect images of the SNP over an area of 2-3 mm around the whorl-like pattern.Captured images at each time were merged into one image by using the Photoshop CC 2017 image processing software, and then the nerve fiber length (NFL) of whorl-like pattern was measured by Neuron J image analysis software.McGill pain questionnaire was used to investigate the pain of patients after each photocoagulation.The NFL changes of SNP at different time points were compared between different eyes and different photocoagulation sequence groups.The study protocol adhered to the Declaration of Helsinki and was approved by an Ethics Committee of Shanxi Eye Hospital (No.201804b). Written informed consent was obtained from each patient prior to entering the study cohort.Results:After PRP treatment, there were different degrees of neural structure loss of SNP nerve fibers in 11 treatment eyes, but there was no significant change in SNP nerve fibers in the control eyes.There were significant differences in NFL between the treatment eyes and the control eyes at various time points ( Feyes=2.020, P=0.039; Ftime=4.062, P=0.001). In the horizontal-vertical laser group, different degrees of neural structure loss on the photocoagulation side were found in SNP nerve fibers after the first and second photocoagulation.In the vertical-horizontal laser group, different degrees of neural structure loss on the photocoagulation side were found in SNP nerve fibers after the third and fourth photocoagulation.There was no significant difference in NFL of treatment eyes between the two groups ( Fgroup=0.099, P=0.754), but there was a significant difference in NFL at various time points before and after treatment ( Ftime=5.231, P<0.001). There were 9 (9/57) patients who complained of pain after PRP, which occurred at the first time of photocoagulation in 7 of them. Conclusions:SNP damage may occur after PRP in patients with DR, and SNP is prone to be damaged on the photocoagulation side when performing horizontal photocoagulation.
