Molecular Mechanism of Electroacupuncture Regulating Cerebral Arterial Contractile Protein in Rats with Cerebral Infarction Based on MLCK Pathway / 中国结合医学杂志

OBJECTIVE@#To explore the effect of electroacupuncture (EA) intervention on the vasoconstriction of cerebral artery smooth muscle cells after cerebral infarction.@*METHODS@#Male Wistar rats were randomly divided into 3 groups by a random number table: the model group (n=24), the EA group (n=24), and the normal group (n=6). The model and the EA groups were divided into different time subgroups at 0.5, 1, 3, and 6 h after middle cerebral artery occlusion (MCAO), with 6 rats in each subgroup. MCAO model was established using intraluminal suture occlusion method. The EA group was given EA treatment at acupoint Shuigou (GV 26) instantly after MCAO for 20 min. The contents of cerebrovascular smooth muscle MLCK, the 3 subunits of myosin light chain phosphatase (MLCP) MYPT1, PP1c-δ and M20, as well as myosin-ATPase activity were detected using immunohistochemistry and Western blotting.@*RESULTS@#The overall expression level of the MYPT1 and PP1c-δ in the model group was significantly higher (P<0.01). After EA intervention, the 0.5 h group expression level was close to that of the normal group (P>0.05), and the other subgroups were still significantly higher than the normal group (P<0.01). After EA intervention, the expression level of each subgroup was significantly lower than the corresponding model group. There was a significant difference between the 0.5 and 1 h subgroups (P<0.01), while a difference was also observed between the 3 and 6 h subgroups (P<0.05). The dynamic change rule gradually increased with the prolongation of infarction time within 6 h after infarction.@*CONCLUSION@#EA intervention can inhibit contraction of cerebral vascular smooth muscle cells and regulate smooth muscle relaxation by regulating MLCK pathway.

Construction of a core outcome set in clinical research of acupuncture and moxibustion for treatment of adhesive capsulitis / 中国针灸

This study aims to construct the core outcome set for the clinical trials of adhesive capsulitis treated with acupuncture and moxibustion. Using systematic review, semi-structured interview, Delphi questionnaire survey, analytic hierarchy process and expert consensus meeting, the primary outcomes are obtained, i.e. local tenderness, pain degree during movement, range of motion, changes in range of motion, function score, and score of local symptoms of shoulder joint. The secondary outcomes are myofascial thickness, thickness of the inferior wall of the joint capsule, health status, activity of daily living, incidence of adverse events, laboratory indexes, vital signs, cost-effectiveness, total effective rate, and patient satisfaction. It is expected to provide a reference for the outcome selection in clinical trials and the generation of medical evidences in the treatment of adhesive capsulitis with acupuncture and moxibustion.

Application of meridian and acupoint diagnosis of three yin meridians of foot in the treatment for gynecological diseases with acupuncture and moxibustion / 中国针灸

With three representative types of gynecological diseases (dysmenorrhea, pelvic inflammation, polycystic ovary syndrome) as examples, the application methods of meridian and acupoint diagnosis for gynecological diseases treated with acupuncture and moxibustion are discussed. During clinical diagnosis and treatment, it is recommended to examine the patient's leg segment along the three yin meridians of foot, aiming to explore the positive reactions of the meridians and acupoints (color, shape, skin temperature, sensory abnormalities, etc.). Acupuncture and moxibustion treatment at this positive reaction place can improve the clinical efficacy. Meridian and acupoint diagnosis could provide basis for meridian syndrome differentiation, thus guiding the selection of acupoint prescriptions; it is also helpful to clarify the deficiency, excess, cold and heat of the disease nature, thus guiding the selection of acupuncture and moxibustion methods. In addition, it is an auxiliary method to estimate the prognosis and outcome of the disease.

From the body-mind holism to psychosomatic medicine: theory and practice of acupuncture and moxibustion / 中国针灸

The traditional life concept of "body-mind holism" in Chinese medicine has drawn a special attention with the development of modern psychosomatic medicine. The "body-mind holism" is valuable in the guidance for clinical acupuncture practice, but, it is only remained on the theoretical significance by the medical masters in the past dynasties. In the paper, based on the understanding of Huangdi Neijing (Yellow Emperor's Internal Classic), the similarities and differences are compared between the body-mind theory and psychosomatic medicine. In association with clinical observation, from three aspects, i.e. body-mind pathogenesis, acupoint detection and observing the mind, and body-mind treatment, the guidance of "body-mind holism" is explored for the clinical diagnosis and treatment of acupuncture and moxibustion; the referents of "body" and "mind" are clarified in views of disease, diagnosis and treatment; and the treatment strategies of acupuncture and moxibustion are discussed in the perspective of "body-mind holism".

Objective:To investigate the effect of modified holmium laser enucleation of the prostate (HoLEP) in patients with large-volume benign prostatic hyperplasia (BPH), and the effect on urethral function, pain mediators, epidermal growth factor (EGF) and prostate specific antigen (PSA).Methods:The clinical data of 83 patients with large-volume BPH in Dalian Central Hospital from October 2019 to April 2021 were retrospectively analyzed. Among them, 42 patients were treated with modified HoLEP (modified HoLEP group), and 41 patients were treated with transurethral resection of the prostate (TURP; TURP group). The procedure-related indexes (operative time, hospital stay, duration of urinary catheter retention, bladder flushing time and hemoglobin loss) were compared between 2 groups; the serum levels of pain mediators including substance P (SP), prostaglandin E 2 (PGE 2), calcitonin gene-related peptide (CGRP) before surgery and 1, 3 days after surgery were measured; the serum levels of EGF and PSA before surgery and 1, 2 weeks after surgery were measured; postoperative complications were counted; the maximum urinary flow rate, residual urine volume and bladder compliance before surgery and 3, 6 months after surgery were measured to assess urethral function; the improvement of symptoms before surgery and 3, 6 months after surgery were assessed by the overactive bladder symptom score scale, the international prostate symptom score scale and the quality of life index scale. Results:There was no statistical difference in operative time between 2 groups ( P>0.05); the hospital stay, duration of urinary catheter retention and bladder flushing time in modified HoLEP group were significantly shorter than those in TURP group: (4.52 ± 1.07) d vs. (5.74 ± 1.46) d, (2.87 ± 0.72) d vs. (4.84 ± 0.93) d, (18.29 ± 6.75) d vs. (28.54 ± 10.68) d, the hemoglobin loss was significantly lower than that in TURP group: (2.96 ± 0.84) g vs. (13.17 ± 5.69) g, and there were statistical differences ( P<0.01). There were no statistical differences in SP, PGE 2 and CGRP before surgery between 2 groups ( P>0.05); the SP, PGE 2 and CGRP 1 and 3 d after surgery in modified HoLEP group were significantly lower than those in TURP group, and there were statistical differences ( P<0.01). There were no statistical differences in EGF, PSA, urethral function and symptoms improvement before and after surgery ( P>0.05). The incidence of postoperative complications in modified HoLEP group was significantly lower than that in TURP group: 9.52% (4/42) vs. 29.27% (12/41), and there was statistical difference ( P<0.05). Conclusions:Modified HoLEP for the treatment of large-volume BPH patients can effectively reduce the incidence of postoperative complications, further reduce the level of pain mediators, and effectively shorten the postoperative recovery process.

Clinical feature analysis of subdural effusion/hematoma after shunt use of adjustable valves in children with hydrocephalus / 中华实用儿科临床杂志

Objective:To analyze the clinical data of children with hydrocephalus suffering from subdural effusion/hematoma after shunt(SEHS) with adjustable valves, and to provide reference for postoperative follow-up.Methods:A total of 102 children with hydrocephalus treated with adjustable valves in the Department of Neurosurgery, Wuhan Children′s Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology from August 2017 to September 2021 were enrolled and studied retrospectively.There were 16 cases with SEHS, 11 of whom were male and 5 were female.The age ranged from 3 months to 13 years (median: 2.5 years). The age, clinical manifestations, the time of SEHS occurrence, treatment methods(pressure regulation only or combined with drilling and drainage), and prognosis of the patients were analyzed.The pressure adjustment treatment was to increase the by 10-20 mmH 2O (1 mmH 2O=0.009 8 kPa) each time and the patients were followed up 2-4 weeks after the adjustment.If SEHS didn′t improve according to the follow-up results, pressure regulation combined with drilling and drainage was recommended. Results:Of the 16 patients with SEHS, 3 cases were over 3 years old, and the other 13 cases were 3 years old or below.Eleven cases were treated by pressure regulation only, and 5 cases who were all aged ≤3 years received pressure regulation combined with drilling and drainage.Symptoms occurred in 2 patients, including vomiting in 1 case, and head and limb shaking in the other case.Fourteen cases were asymptomatic.The time from shunt operation to the occurrence of SEHS was ≤1 month in 5 cases, who were all cured by pressure regulation only.SEHS occurred in 5 cases >1-3 months after shunt surgery, and 2 cases of them were treated by pressure regulation combined with dri-lling and drainage.Three cases had SEHS>3-6 months after shunt surgery, and 1 case of them was treated by pressure regulation combined with drilling and drainage.SEHS occurred in 3 cases more than 6 months after shunt surgery, and 1 case of them was treated by pressure regulation combined with drilling and drainage.For the patients who received pressure regulation combined with drilling and drainage, the time from shunt operation to the occurrence of SEHS was 1 month and 21 days, 2 months and 7 days, 4.5 months, 7.5 months, and 25.0 months, respectively.The time from the occurrence of SEHS to the last reexamination with no SEHS detected was ≤1 month in 7 cases (all were cured by pressure regulation only); >1-3 months in 5 cases (3 cases were treated by pressure regulation combined with drilling and drainage); more than 3 months in 4 cases (2 cases were treated by pressure regulation combined with drilling and drainage). For the patients who received pressure regulation combined with drilling and drainage, the time from the occurrence of SEHS to the last reexamination with no SEHS detected was 1 month and 14 days, 2.0 months, 3.0 months, 7.0 months and 8.0 months, respectively.Except for 2 cases who experienced pressure regulating valve failure, all other cases were cured.Six cases were unilateral SEHS, and the SEHS volume was about 11 to 75 mL (median: 39.0 mL). Ten cases were bilateral SEHS, and the SEHS volume was about 23-380 mL (median: 158.2 mL). The 6 cases were all cured by pressure regulation, and 5 cases of them had SEHS at the shunt tube insertion side.Conclusions:SEHS in children with hydrocephalus is generally asymptomatic and rarely causes clinical symptoms.SEHS mostly occurs within 6 months after operation, especially within 3 months.SEHS found in 1 month after surgery can be cured by increasing the shunt valve pressure only.Therefore, SEHS can be cured by pressure regulation only by shortening follow-up and identifying SEHS early after shunt operation.This will also reduce the probability that patients require the drilling and drainage operation.

Transcriptomic Changes of Astrocytes in the Brain of Rats with Subacute METH Exposure / 法医学杂志

OBJECTIVES@#To study the transcriptomic changes of astrocytes in the brain of rats exposed to methamphetamine (METH) and its possible mechanism in neurotoxicity.@*METHODS@#The rats were intraperitoneally injected with METH (15 mg/kg) every 12 h for 8 times in total to establish the subacute rat model of METH. After the model was successfully established, the striatum was extracted, and astrocytes were separated by the magnetic bead method. Transcriptome sequencing was performed on selected astrocytes, and the differentially expressed genes were analyzed by gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis.@*RESULTS@#A total of 876 differentially expressed genes were obtained by transcriptome sequencing, including 321 up-regulated genes and 555 down-regulated genes. GO analysis revealed that differentially expressed genes were mainly concentrated in cell structure, biological process regulation, extracellular matrix and organelle functions. KEGG pathway enrichment analysis showed that steroids biosynthesis, fatty acid biosynthesis, peroxisome proliferators-activated receptor (PPAR), adenosine 5'-monophosphate-activated protein kinase (AMPK) and other signaling pathways were significantly changed.@*CONCLUSIONS@#METH can cause structural changes of astrocytes through multiple targets, among which cellular structure, steroids biosynthesis and fatty acid biosynthesis may play an important role in nerve injury, providing a new idea for forensic identification of METH related death.

OBJECTIVE@#To explore the effect of scalp acupuncture combined with suspension training on balance ability and motor function in stroke patients with balance dysfunction.@*METHODS@#A total of 105 stroke patients with balance dysfunction were randomly divided into a combined group (35 cases, 2 cases dropped off), a scalp acupuncture group (35 cases, 3 cases dropped off) and a suspension training group (35 cases, 2 cases dropped off). The scalp acupuncture group was treated with scalp acupuncture at bilateral suboccipital lateral line, parietal midline, upper 1/5 line of anterior oblique line of parietal and temporal and line 1 of the parietal lateral line on the opposite side of hemiplegia. The suspension training group was treated with suspension training. The combined group was treated with suspension training at the same time of scalp acupuncture. All the treatment was given once a day, 30 min each time, 5 days a week, for a total of 6 weeks. The Berg balance scale (BBS) score, balance tester and Fugl-Meyer assessment (FMA) score were used to evaluate the motor function and balance ability before treatment, 3 and 6 weeks into treatment. The clinical efficacy was evaluated in the 3 groups.@*RESULTS@#The scores of BBS and FMA in each group at 3 and 6 weeks into treatment were higher than those before treatment (@*CONCLUSION@#Scalp acupuncture combined with suspension training could improve the balance ability and motor function in stroke patients with balance dysfunction, and the curative effect is better than simple scalp acupuncture and simple suspension training.

Research progress on mechanisms of bidirectional regulation of acupuncture / 中国针灸

Bidirectional regulation is one of the key function of acupuncture. The stimulator, mediator and receptor are the basis while the specificity of acupoints and the multi-target regulation of receptors receiving stimulation signals are the essential link of the bidirectional regulation of acupuncture. The possible mechanisms of bidirectional regulation of acupuncture are discussed in 4 aspects, i.e. homeostasis mechanism, stress reaction, central adaptive regulation and autonomic nerve regulation. Knowing the limitations of bidirectional regulation and exploring suitable researchmethods are proposed to be the key points in future researches.

Comparison of short-term effects of arthroscopic and open reduction and internal fixation with Herbert screws in treatment of radial head fractures / 中华创伤杂志

Objective:To compare the short-term clinical effect of arthroscopic and open reduction and internal fixation with Herbert screws in treatment of Mason type II radial head fractures.Methods:A retrospective case-control study was conducted to analyze the clinical data of 38 patients with unilateral radial head fractures (Mason type II) admitted to Shanghai Zhongye Hospital from January 2017 to December 2018, including 22 males and 16 females, aged from 20 to 65 years [(37.4±12.6)years]. Twenty patients were treated by arthroscopic reduction and internal fixation with Herbert screw (Group A), and eighteen by open reduction and internal fixation with Herbert screw (Group B). The operation time and fracture healing time were recorded. The visual analogue scale (VAS), elbow flexion and extension range, forearm rotation range and Mayo elbow function score were compared between the two groups before and at 1, 3, 6, and 12 months after operation. The results of Mayo elbow performance score (MEPS) and upper limb function assessment using the disabilites of the arm, shoulder, and hand (DASH) score were compared between the two groups. Complications including screw breakage or fracture displacement were also evaluated.Results:All patients were followed up for 12-14 months [(12.3±2.3)months]. There was no significant difference in operation time between the two groups ( P>0.05). The fracture healing time was (8.9±0.6)weeks in Group A and (8.7±0.6)weeks in Group B ( P>0.05). There was no significant difference in VAS between the two groups before operation ( P>0.05). The VAS was (4.8±0.5)points at 1 month after operation in Group A, lower than (6.0±0.7)points in Group B ( P<0.05). There was no significant difference in VAS between Group A and Group B at 3, 6, and 12 months after operation ( P>0.05). There was no significant difference in elbow flexion and extension range between the two groups before operation ( P>0.05). The elbow flexion and extension range in Group A was (110.4±3.8)° and (137.1±4.0)° at 1, 3 months after operation, which was significant greater than (90.6±4.7)° and (125.1±3.5)° in Group B ( P<0.05). There was no significant difference in elbow flexion and extension range between the two groups at 6 and 12 months after operation ( P>0.05). There was no significant difference in the range of forearm rotation between the two groups before operation ( P>0.05). The range of forearm rotation in Group A was (107.1±2.8)° and (138.1±2.9)° at 1, 3 months after operation, significantly greater than (95.5±3.9)°, (121.5±3.0)° in Group B ( P<0.05). There was no significant difference in forearm rotation range between the two groups at 6 and 12 months after surgery ( P>0.05). There was no significant difference in MEPS between the two groups before operation ( P>0.05). The MEPS in Group A was (50.4±3.8)points at 1 month after operation, higher than (40.6±4.7)points in Group B ( P<0.05). There was no significant difference in MEPS between the two groups at 3, 6, and 12 months after operation ( P>0.05). There was no significant difference in DASH score between the two groups before operation ( P>0.05). The DASH score was (57.1±2.8)points at 1 month after surgery in Group A, higher than (42.5±3.9)points in Group B ( P<0.05). The DASH score was not significantly different between the two groups at 3, 6, and 12 months after operation ( P>0.05). There was no screw loosening or fracture after operation, and one patient in each group had fracture displacement ( P>0.05). Conclusion:For Mason type II radial head fractures, arthroscopic Herbert screw fixation has the advantages of less trauma, less pain and faster functional recovery of the affected limb compared with open reduction and Herbert screw fixation.

Gene editing: an instrument for practical application of gene biology to plant breeding / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

Plant breeding is well recognized as one of the most important means to meet food security challenges caused by the ever-increasing world population. During the past three decades, plant breeding has been empowered by both new knowledge on trait development and regulation (e.g., functional genomics) and new technologies (e.g., biotechnologies and phenomics). Gene editing, particularly by clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein (Cas) and its variants, has become a powerful technology in plant research and may become a game-changer in plant breeding. Traits are conferred by coding and non-coding genes. From this perspective, we propose different editing strategies for these two types of genes. The activity of an encoded enzyme and its quantity are regulated at transcriptional and post-transcriptional, as well as translational and post-translational, levels. Different strategies are proposed to intervene to generate gene functional variations and consequently phenotype changes. For non-coding genes, trait modification could be achieved by regulating transcription of their own or target genes via gene editing. Also included is a scheme of protoplast editing to make gene editing more applicable in plant breeding. In summary, this review provides breeders with a host of options to translate gene biology into practical breeding strategies, i.e., to use gene editing as a mechanism to commercialize gene biology in plant breeding.

Efficacy of group cognitive-behavioral therapy for diabetic patients with anxiety and depression / 上海预防医学

Objective To explore the efficacy of group cognitive-behavioral therapy(GCBT) for diabetic patients with anxiety and depression. Methods In this randomized control study, 42 patients was recruited for treatment of diabetes and allocated them in a randomized manner (1:1) into two groups to receive either 10-weeks GCBT plus regular education or regular education alone.Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD), Self-rating Depression Scale(SDS), and fasting blood glucose were measured and evaluated before and after treatment. Results After 10 weeks of intervention, the total scores of HAMD, HAMA, and SDS were significantly decreased.Compared with the control group, repeated measures of ANOVA revealed a significant group-by-time interaction(F=6.801, 10.30, 5.02, P=0.013, 0.003, 0.031).The difference of HAMD was negatively correlated with disease duration and education (r=-0.486, -0.541, P=0.030, 0.014), and the difference of SDS was obviously correlated with gender, as the SDS score of women decreased more significantly (r=0.582, P=0.007). Conclusion Group cognitive-behavioral therapy can help to improve the mood of diabetic patients with anxiety and depression, rehabilitating their social function and life quality.

Retrospective Analysis of 61 Cases of Children Died of Viral Pneumonia / 法医学杂志

Objective To retrospectively analyze the forensic pathological postmortem examination and clinical data of children who died of viral pneumonia in identification of cause of death cases and to discuss the clinical characteristics and pathological features of viral pneumonia in children, in order to provide reference to pathological diagnosis of viral pneumonia in children caused by 2019 novel coronavirus （2019-nCoV） infection. Methods Postmortem examination data from 61 cases of children whose causes of death were identified as viral pneumonia in recent years were collected from the Center of Forensic Identification, Southern Medical University. The gender, age, clinical symptoms and pathological features were comparatively analyzed. Results Among the 61 cases of children who died of viral pneumonia, most were within 2 years old （83.61%）, and a large proportion died within 2 weeks after the onset of the disease （91.80%）. Gross changes in postmortem examination included respiratory mucosal hyperemia, pleural effusion, pulmonary swelling, variegated pulmonary pleura and serosa, as well as focal pulmonary hemorrhage and pulmonary edema. A large proportion of sick children had enlarged mesenteric lymph nodes （83.61%） and thymic dysplasia （21.31%）. Histopathological changes included edema of alveoli and interstitial substance, pneumorrhagia，shedding of alveolar epithelial cells, serous and （or） fibrous exudation in the alveoli, formation of viral inclusions, formation of transparent membranes, infiltration of inflammatory cells that mainly consisted of macrophages and lymphocytes in interstitial substance and alveoli. Viral infections often affected the heart and gastrointestinal tract. Conclusion The clinical symptoms of children with viral pneumonia are difficult to notice, and because the immune systems of children are not fully developed and they have poor immunity, they can easily become severely ill and even die. Analyzing the forensic autopsies and the histopathological characteristics could provide reference for pathological diagnosis of viral pneumonia.

Review and Prospect of Pathological Features of Corona Virus Disease / 法医学杂志

Since 2003, coronavirus has caused multiple major public health events that resulted in global epidemics, such as severe acute respiratory syndrome （SARS）, Middle East respiratory syndrome （MERS） and corona virus disease 2019 （COVID-19）. Especially since COVID-19 outbroke in Wuhan, Hubei, in December 2019, coronavirus has had a significant impact on people's health and lives. But so far, the pathological diagnosis of COVID-19 has been relatively deficient： it is still confined to the pathological findings of punctured organs, and the majority of medical workers have poor awareness of its pathological characteristics. The COVID-19, as same as SARS and MERS, is caused by coronaviruses and can cause viral pneumonia. They have certain similarities. This article comprehensively reviews the pathological features observed in the autopsies of the aforementioned three diseases, in order to provide reference to the analysis of pathological changes of COVID-19.

Assessment of neonatal brain development by 2D1H-MRS at 3.0T / 西安交通大学学报(医学版)

Objective To compare metabolite ratios in the basal ganglia regions between preterm and term neonates and analyze the correlation between metabolite ratio and postmenstrual age(PMA)using 2D magnetic resonance spectroscopy(MRS)at 3.0T,so as to explore the value of MRS in evaluating neonatal brain development.Methods Normal neonates who underwent 3.0T MRS exam ination were recruited.Axial 2D MRS was performed with the point-resolved spectroscopy sequence(PRESS)(echo time/repetition time,144 ms/1 000 ms) through the basal ganglia covering three regions of interest(ROI)(i.e.bilateral lenticular nucleus,thalamus and white matter beside the anterior horn of lateral ventricle).The peak areas ratios of Cho/Cr,NAA/Cho and NAA/Cr were calculated.Metabolite ratios were compared between preterm and term neonates,and between three ROIs. Correlation between metabolite ratio and PMA was further analyzed.Results Totally 54 neonates were included(preterm/term,27/27).In all the three ROIs,preterm neonates presented significantly higher Cho/Cr(P＜0.05) and significantly lower NAA/Cho ratios(P＜0.001)than those of term neonates;higher NAA/Cr ratio was only observed in the lenticular nucleus of preterm neonates(P＜0.001).Significant differences in metabolite ratios were detected among the three ROIs in preterm group(P＜0.05).For term group,metabolite ratios differed between lenticular nucleus and white matter beside the anterior horn of the lateral ventricle(P＜0.01),while no difference between lenticular nucleus and thalamus was found(P＞0.05).Significant correlation between metabolite ratio and PMA was found in all the three ROIs except NAA/Cr ratio in the white matter beside the anterior horn of the lateral ventricle.To be specific,we found linear negative correlation of Cho/Cr ratio(r= -0.325,-0.633,-0.438) and positive correlation of NAA/Cho ratio(r = 0.604,0.773,0.483)in all the three ROIs,but negative correlations of NAA/Cr ratio(r=0.487,0.367)in lenticular nucleus and thalamus with PMA.Conclusion Our findings suggest the tempo-spatial pattern of neonatal brain metabolite development in terms of anatomic location and PMA.Besides,the multi-voxel MRS presents potentials in establishing the normal topologic and age-matched reference in neonates and thus making brain maturation assessment and detection of early abnormal metabolism.

The relationship between changes of Tpeak-Tend interval and ventricular arrhythmias in patients with type 2 diabetes mellitus / 中国糖尿病杂志

Objective To analyze the changes of Tpeak-Tend interval (Tp-Te) in patients with type 2 diabetes mellitus (T2DM),and to explore the relationship between the changes of Tp-Te and ventricular arrhythmias. Methods A total of 112 patients with T2DM were selected from the Department of endocrinology of our hospital from June 2014 to May 2016 (T2DM group),and 65 subjects underwent healthy physical examination in our hospital were selected as the normal control group (NC group) during the same period.The general data,fasting plasma glucose (FPG),glycosylated hemoglobin (HbA1c),Tp-Te,Tp-Te dispersion (Tp-Ted) were compared between the two groups.The changes of Tp-Te in patients with or without ventricular arrhythmia in T2DM group were also analyzed. Results The FPG,HbA1c,LDL-C,TC and heart rate were significantly higher in T2DM group than in the NC group (P<0.05).Compared with the control group,V5 lead Tp-Te and Tp-Ted in T2DM group was significantly prolonged (P<0.05).IN T2DM group,V5 lead Tp-Te and Tp-Ted were significantly longer in patients with ventricular arrhythmias than in patients without ventricular arrhythmia (P<0.05).Multiple logistic regression analysis showed that the increase of HbA1c and FPG were independent risk factors for prolonged Tp-Ted,and Tp-Ted was an independent risk factor for ventricular arrhythmia. Conclusion Patients with T2DM are more likely to have prolonged Tp-Ted.The prolonged Tp-Te and Tp-Ted could increase the incidence of ventricular arrhythmias.

The effects of sleeve gastrectomy on renal function in type 2 diabetic rats / 中华外科杂志

<p><b>OBJECTIVE</b>To examine the renal function changes and mechanisms on rats with diabetes through a sleeve gastrectomy operation.</p><p><b>METHODS</b>Thirty-six rats were induced diabetes through injection of streptozotocin (STZ), and 30 of these diabetic rats that blood glucose levels at the midrange (blood sugar 17.88-23.65 mmol/L, mean: 20.32 mmol/L) were randomly assigned to the sleeve gastrectomy group, Sham-operation group and control group. The serum creatinine, lipid parameters were measured postoperatively. The 24 h urine volume obtained and urine albumin excretion rate (UAER) was calculated. Serum and urinary creatinine were examined and glomerular filtration rate (GFR) was counted. Kidney sections were stained with periodic acid-Schiff, and then the index of mesangial expansion was determined. The expression of synaptopodin for podocytes was also performed through the immunohistochemical procedure. A one-way ANOVA and t-test were performed to evaluate differences between groups and each other.</p><p><b>RESULTS</b>Only one rat of SG group died after operation. The GFR ((8.44 ± 2.10) ml · g⁻¹ · d⁻¹), 24 h UAER ((36.04 ± 11.10) mg/d), plasma lipids level (total cholesterol (1.66 ± 0.23) mmol/L, triglycerides (1.25 ± 0.17) mmol/L), kidney weight ((1.61 ± 0.06) g), the index of mesangial expansion ((6.14 ± 1.50)%) and synaptopodin expression ((20.44 ± 2.99)%) were improved in the SG group compared with the sham-operation group ((15.05 ± 3.01) ml · g⁻¹ · d⁻¹, (57.01 ± 11.34) mg/d, (2.15 ± 0.29) mmol/L, (1.65 ± 0.23) mmol/L, (1.93 ± 0.07) g, (11.32 ± 2.09)%, (10.34 ± 1.43)%) and control group ((14.79 ± 2.38) ml · g⁻¹ · d⁻¹, (62.71 ± 16.46) mg/d, (2.23 ± 0.21) mmol/L, (1.59 ± 0.20) mmol/L, (1.91 ± 0.06) g, (10.82 ± 1.79)%, (11.13 ± 2.43)%) (t = 0.781-5.025, all P < 0.05).</p><p><b>CONCLUSION</b>The sleeve gastrectomy procedure can improve the renal function in a diabetes rat model may be through protecting the podocytes function and preventing the mesangial expansion of glomeruli.</p>
