Study on the correlation between gene polymorphisms of adiponectin and resistin levels and abdominal aortic aneurysm

Abstract Objectives: Abdominal Aortic Aneurysm (AAA) is a complex disease with both genetic and environmental risk factors. This study aimed to examine the potential association of the +276G/T and −420C>G polymorphisms in the resistin gene with AAA susceptibility and progression. Method: We performed a retrospective study involving AAA patients and healthy controls, assessing the distribution of the +276G/T and −420C>G genotypes in both groups. Hardy-Weinberg equilibrium was assessed for both polymorphisms. Logistic regression was used to explore the influence of these genotypes on AAA occurrence and progression, adjusting for relevant confounders. Results: The distribution of +276G/T polymorphism did not significantly differ between AAA patients and controls. Conversely, a significant difference was observed in the genotype distribution of −420C>G polymorphism between the two groups. The CC genotype and CC/CG genotypes of −420C>G polymorphism were found to be associated with an increased risk and progression of AAA. Conclusions: The −420C>G polymorphism, particularly the CC genotype and CC/CG genotypes, might play a substantial role in AAA susceptibility and progression. The present findings underscore the need for further investigations to confirm these associations and fully elucidate the role of the resistin gene in AAA.

Study on alternative method for vasopressin impurity test of oxytocin injection from biological extraction / 中国药理学通报

Aim To explore the alternative study on rat blood pressure method and HPLC method for vasopressin impurity test of oxytocin injection from biological extraction. Methods The HPLC method for the vasopressin impurity test in vitro was established and validated. The bio-extrac tion oxytocin injection samples and simulated samples were examined for vasopressin impurity by HPLC and rat blood pressure methods respectively. Results Vasopressin and adjacent impurity peaks were successfully separated by the established method. In the range of 210~13 330 IU•L -1the concentration of vasopressin had a good linear relationship with its peak area with r=0.999 9. The results of HPLC method were consistent with the biological examination method-rat blood pressure method in the current standard. Conclusions The method is proved to be specific, sensitive, and accurate, which can be used as a test method for vasopressin impurity to replace the rat blood pressure method in the current standard.

Research Status and Prospects of Non-Traumatic Fat Embolism in Forensic Medicine / 法医学杂志

In the practice of forensic pathology, fat embolism is one of the common causes of death, which can be divided into two categories: traumatic and non-traumatic. Non-traumatic fat embolism refers to the blockage of small blood vessels by fat droplets in the circulatory blood flow caused by non-traumatic factors such as underlying diseases, stress, poisoning and lipid metabolism disorders. At present, it is believed that the production of non-traumatic fat embolism is related to the disturbance of lipid metabolism, C-reactive protein-related cascade reaction, the agglutination of chylomicron and very low-density lipoprotein. The forensic identification of the cause of death of non-traumatic fat embolism is mainly based on the case, systematic autopsy, HE staining and fat staining, but it is often missed or misdiagnosed by forensic examiners because of its unknown risk factors, hidden onset, the difficulty of HE staining observation and irregular implementation of fat staining. In view of the lack of attention to non-traumatic fat embolism in forensic identification, this paper reviews the concepts, pathophysiological mechanism, research progress, existing problems and countermeasures of non-traumatic fat embolism, providing reference for forensic scholars.

Comparative study on the efficacy of different ways of common sclerosing agents used in ultrasonic intervention on the treatment of ovarian endometriosis cyst / 中华超声影像学杂志

Objective:To compare the efficacy of anhydrous ethanol and lauromacrogol in the treatment of ovarian endometriosis cyst (OEC), and to provide evidence for more effective use of these two sclerotic drugs.Methods:Thirty-three cysts in 30 patients with OEC, who were admitted to Taizhou Hospital of Zhejiang Province from February 2017 to June 2018, were treated by ultrasound interventional therapy, followed by catheter aspiration, saline cavity cleaning, anhydrous ethanol rinsing and sclerotherapy, and lauromacrogol alcohol 1∶1 mixed solution retained in the capsule (mixed group). The therapeutic effects were observed 6 and 12 months after operation. A total of 30 OEC in 28 cases admitted to the same hospital from 2013 to 2015 were retrospectively analyzed after similar treatment steps, but the intracapsular retention fluid was anhydrous ethanol (ethanol group). A total of 28 OEC in 26 patients admitted to the same hospital from 2015 to 2017 were washed with normal saline, then washed with lauromacrogol and retained in the capsule with lauromacrogol (lauromacrogol group). The therapeutic effects of 6 and 12 months after treatment between the three groups were compared.Results:According to the classification of cure, marked effect and inefficacy, there was a weak correlation among the three groups. The mixed group did not tend to be ineffective, while the lauromacrogol group tended to be ineffective 6 and 12 months after treatmen.the difference was statistically significant (adjusted standardized residual >2). According to the total effective (cure+ markedly effective) and ineffective classification, the effective rate of the mixed group was significantly higher than that of the lauromacrogol group ( P<0.016 7). There was no significant difference for the effective rate between the mixed group and the ethanol group, and between the ethanol group and the lauromacrogol group ( P>0.0167). Conclusions:The retention of ethanol-lauromacrogol mixture in the capsule of sclerotic OEC, after pre-rinsing with anhydrous ethanol is helpful to improve the curative effect of OEC and give full play to the therapeutic effect of common sclerosing agents used in ultrasound intervention.

Clinical characteristics and related factors of systemic lupus erythematosus with interstitial pneumonia / 北京大学学报(医学版)

OBJECTIVE@#To investigate the clinical features, radiologic scores and clinically relevant risk factors prognosis of secondary interstitial lung disease (ILD) in patients with systemic lupus erythematosus (SLE).@*METHODS@#In this study, 60 SLE patients in Department of Rheumatology of the First Affiliated Hospital of Baotou Medical College and Taizhou First People's Hospital from January 2015 to March 2019 were retrospectively analyzed. All of those 60 patients with SLE underwent lung high resolution computed tomography (HRCT) examination. We used a 1 ∶1 case-control study. There was a matching of age and gender between the two groups. Thirty patients with SLE related ILD (SLE-ILD) were in the case group, and 30 patients with SLE without ILE (SLE non-ILD) were in the control group. The clinical features, pulmonary function test, radiologic characteristic of SLE patients were collected and were used to analyze SLE-ILD.@*RESULTS@#In this study, we reached the following conclusions: First, there were statistically significant differences in chest tightness/shortness of breath, Raynaud's phenomenon, and Velcro rale between SLE-ILD and SLE non-ILD patients (both P < 0.05); Second, hemoglobin (Hb) and albumin (ALB) in the patients of SLE-ILD had a significant decrease compared with the patients of SLE non-ILD. Blood urea nitrogen (BUN), erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) increased in SLE-ILD patients compared with SLE non-ILD patients, the difference had statistical significance (P < 0.05); Third, for SLE-ILD patients, the most common type was non-specific interstitial pneumonia (NSIP), followed by usual interstitial pneumonia and lymphocytic interstitial pneumonia; Fourth, there was no significant difference in clinical-radiology-physiology scores between the different ILD types (P>0.05), similarly, the lung HRCT score and lung function between different ILD types had no significant difference (P>0.05); Fifth, multivariate Logistic regression analysis showed that decreased albumin and chest tightness/shortness of breath might be the risk factor for SLE-ILD.@*CONCLUSION@#There are statistically significant differences between the SLE-ILD group and SLE non-ILD group in terms of chest tightness/shortness of breath, Velcro rale and Raynaud's phenomenon. Decreased albumin and chest tightness/shortness of breath in SLE patients should be alerted to the occurrence of ILD. NSIP is the most common manifestation of SLE-ILD.

Relationship between cerebral hemorrhage and depression occurrence after craniocerebral injury surgery / 中国医师杂志

Objective To explore the relationship between cerebral hemorrhage and the occurrence of depression after craniocerebral injury surgery.Methods From March 2015 to March 2017,70 patients with craniocerebral injury in our hospital were selected as the subjects of study.They were divided into the observation group (n =30) and the control group (n =40) according to whether there was cerebral hemorrhage after operation.The National Institutes of Health Stroke Scale score (NIHSS),Hamilton Depression Scale score (HAMD),Glasgow Coma Score (GCS) and the levels of interleukin (IL)-1,IL-6 and high sensitivity C-reactive protein (hs-CRP) in patients with different degrees of cerebral hemorrhage were compared.The correlation between HAMD score and other indexes was analyzed.The influencing factors and independent risk factors of depression were analyzed.Results The levels of NIHSS,HAMD score and serum IL-1,IL-6 and hs-CRP in the observation group were higher than those in the control group after operation (t =13.655,36.587,45.274,46.334,70.489,P ＜ 0.05),while the GCS score was lower than that in the control group (t =15.517,P ＜ 0.05).Compared with mild and moderate cerebral hemorrhage,the NIHSS,HAMD scores and serum IL-1,IL-6 and hs-CRP were higher in patients with severe cerebral hemorrhage (F =8.825,10.254,23.615,18.745,7.245,P ＜ 0.05),while the GCS score was lower (F =7.459,P ＜ 0.05).The correlation analysis showed that the postoperative HAMD score was positively correlated with NIHSS score and serum IL-1,IL-6 and hs-CRP (r =0.289,0.364,0.333,0.258,P ＜ 0.05)and negatively correlated with the GCS score (r =-0.276,P ＜ 0.05).Univariate analysis showed that the level of culture,personality,cerebral hemorrhage degree and serum IL-6 and hs-CRP were the influencing factors of postoperative depression in patients with craniocerebral injury (t orx2 =6.076,6.300,8.361,30.224,99.575,P ＜ 0.05).Multivariate analysis showed that cerebral hemorrhage and hs-CRP were an independent risk factor for postoperative depression (P ＜ 0.05).Conclusions Cerebral hemorrhage after craniocerebral injury is closely related to the occurrence of depression,which may be related to the increase of stress-induced inflammatory factors after cerebral hemorrhage.

Comparison of three internal fixation methods for treatment of intertrochanteric fracture of the femur in elder patients / 中国组织工程研究

BACKGROUND: At present, the treatment methods for intertrochanteric fracture of the femur in the aged are in two ways: Intramedullary fixation and extramedullary fixation. The advantages of intramedullary fixation with simple operation, small trauma and few complications have become the gold standard for the treatment of intertrochanteric fracture in the femur in the aged. OBJECTIVE: To explore the clinical curative effects of three internal fixation methods: dynamic hip screw, proximal femoral nail antirotation, and intramedullary nail InterTan in the treatment of intertrochanteric fractures of the femur in the aged. METHODS: A retrospective analysis of 120 cases of intertrochanteric fractures from January 2010 to January 2016 was performed. The patients were randomly divided into dynamic hip screw group (n=40), proximal femoral nail antirotation group (n=60) and InterTan group (n=20). The operative time, intraoperative blood loss, incision length, hospitalization time, postoperative weight-bearing time, fracture healing time, Harris score, and intraoperative and postoperative complications were recorded and compared among the three groups. RESULTS AND CONCLUSION: (1) Operative time, intraoperative blood loss, and incision length were significantly better in the InterTan group and proximal femoral nail antirotation group than in the dynamic hip screw group (P < 0.05). Above indexes were not significantly different between InterTan and proximal femoral nail antirotation groups (P > 0.05). (2) Postoperative weight-bearing time, fracture healing time, and Harris score one month after operation were significantly better in the InterTan group than in the proximal femoral nail antirotation and dynamic hip screw groups; above indexes were better in the proximal femoral nail antirotation group than in the dynamic hip screw group (P < 0.05). (3) Hospitalization time and Harris score at 6 and 12 months after operation were not significantly different among the three groups (P > 0.05). (4) The incidence rate of intraoperative and postoperative complications was significantly lower in the InterTan group and proximal femoral nail antirotation group than in the dynamic hip screw group (P < 0.05). (5) In summary, compared with dynamic hip screw system, proximal femoral nail antirotation and InterTan system are characterized by small trauma, simple operation, quick recovery, and fewer complications, and show good clinical therapy in the treatment of intertrochanteric fracture. Compared with proximal femoral nail antirotation system, InterTan system shows better fracture reduction and stability, shorter healing time, and better biomechanical advantages.

All cases were randomly divided into sufentanil group (Group S) and dexmedetomidine combined with sufentanil group (Group DS) according to the random number table, who used patient-controlled intravenous analgesia (PCIA). The PCIA drug formulations of two groups were as followings: sufentanil group (Group S) used 3 μg/h sufentanil+ondansetron 16 mg, dissolved in 0.9%sodium chloride injection 100 ml;dexmedetomidine combined with sufentanil group (Group DS) used dexmedetomidine 0.1μg/(kg · h)+sufentanil 2μg/h+ondansetron 16 mg, dissolved in 0.9%sodium chloride injection 100 ml;background infusion rate was 2 ml/h, and loading dose was 2 ml. Dose for patient-controlled analgesia (PCA) was 0.5 ml, and locking time was 15 min. The changes of pain, MAP, HR , sedation scores were recorded at 4 h (T1), 8 h (T2), 24 h (T3) and 48 h (T4) after operation; nausea and vomiting, hypotension, bradycardia, respiratory depression and other adverse reactions were aslo recorded at the same time. At 10 min before induction of anesthesia (T0) and T1-T4 after operation, the CD3+, CD4+, CD8+and NK cell activity of peripheral blood T lymphocyte subsets were determined using flow cytometry, and CD4 +/CD8 + ratio was calculated. Results The levels of MAP and HR in DS group at each time point after operation were lower than those in group S (P<0.05), the level of visual analogue score (VAS) in DS group at different time points were significantly lower than those of s group: (1.8 ± 0.3) scores vs. (2.5 ± 0.5) scores, (1.1 ± 0.5) scores vs. (1.9 ± 0.3) scores, (1.0 ± 0.5) scores vs. (1.8 ± 0.5) scores, (0.8 ± 0.3) scores vs. (1.5 ± 0.6) scores (P < 0.05), Ramsay Sedation score was significantly higher than that of s group: (3.5 ± 0.3) scores vs. (2.4 ± 0.6) scores, (3.3 ± 0.5) scores vs. (2.5 ± 0.3) scores, (3.5 ± 0.6) scores vs. (2.3 ± 0.5) scores, (3.2 ± 0.4) scores vs. (2.2 ± 0.5)scores (P<0.05);nausea and vomiting occurred in two patients after the operation of group DS , which was significantly lower than that of S group (P<0.05);compared with those at T0, CD3+, CD4+, CD4+/CD8+and NK cells in the two groups of patients decreased significantly at the time of T1-T4 (P<0.05);The levels of CD3+, CD4+, CD4+/CD8+and NK cells were significantly higher in group DS at T1- T4 than those in group S(P < 0.05). Conclusions Dexmedetomidine combined with sufentanil for analgesia in patients with lower limb fracture surgery has better effect. It decreases the incidence of nausea and vomiting, and improves the cellular immune function of patients.

Cloning and expression analysis of C4H gene from Lepidium apetalum / 药学学报

Lepidium apetalum was used as an experimental material in this study. By analyzing the tran-scriptome data of L. apetalum and application of the specific primers, cDNA of cinnamate-4-hydroxylase (C4H) gene was isolated from L. apetalum and named as LaC4H (GenBank accession No. KX064050). Meanwhile, the bioinformatic analysis, prokaryotic expression, purification, tissue-specific expression analysis and expres-sion analysis after methyl jasmonate (MeJA) treatment were carried out. The results indicated that: ① The open reading frame (ORF) of LaC4H was 1 518 bp, which encoded a protein of 505 amino acid residues, with a predicted molecular mass of 57.73 kD. ② Bioinformatic analysis showed that LaC4H protein contained the conserved sequences of cytochrome P450 (CYP450) and 5 substrate recognition sites (SRSs) of CYP73A1, therefore LaC4H protein was a member of CYP450 superfamily. The phylogenetic analysis indicated that LaC4H protein showed the highest homology with C4H protein from cruciferous plants (such as AtC4H from Arabidopsis thaliana). ③ Through the construction of the prokaryotic expression vector pET-32a-LaC4H, the recombinant LaC4H protein was successfully expressed in E. coli BL21 (DE3) cells and the recombinant LaC4H protein was purified by Ni2+ affinity chromatography. ④ Real-time PCR analysis indicated that LaC4H was expressed in a high transcript level in stems, lower levels in leaves and flowers, the lowest level in roots. After MeJA treatment, the expression level of LaC4H in leaves was increased significantly to reach the highest level at 48 h. Furthermore, the expression levels of LaC4H were positively correlated with the flavonoids contents in leaves. The results of this study provide the fundamental information on LaC4H gene in the flavonoids biosyn-thesis pathway of L. apetalum.

Objective To investigate the efficiency of intraoperative neurophysiological monitoring in cervical spinal tumor surgery.Methods Retrospective case-control study comparing 23 cervical spinal tumor patients received surgery under neurophysiological monitoring (case) and 23 cases without neurophysiological monitoring (control).Results All of 46 cases,there were no significant differences of age,gender and preoperative neurological function.Duration of operation and estimated blood loss in the IONM cohort was less than the control group with significant difference.The preoperative JOA score of IONM group and control group were 12.0±2.4 and 12.7±2.1,with no significant difference.The postoperative JOA score of each group were 15.0±1.5 and 15.2±1.7,with no significant difference.The rate of cervical cord neurological improvement of IONM group was higher than control group,but there was no significant difference.In the IONM cohort,abnormal signal appeared in 8 cases,with 1 case developed new postoperative deficit,and the sensitivity and specificity of SEP were 100％ and 77.3％,the sensitivity and specificity of MEP were 100％ and 86.4％.Compared with preoperative SEP,4 cases showed major improvement (baseline increase ＞ 40％),2 cases showed moderate improvement (baseline increase:15％-40％).The coincidence rate of the SEP improvement and the AISA grade was 66.7％.Conclusion IONM could reduce the duration of operation and intraoperative blood loss.Changes of IONM were correlated with postoperative neurological function improvement.

Effect of ischemic postconditioning on myocardial injury in patients undergoing cardiac valve replacement under cardiopulmonary bypass / 中华麻醉学杂志

Objective To evaluate the effect of ischemic postconditioning on myocardial injury in the patients undergoing cardiac valve replacement under cardiopulmonary bypass (CPB).Methods Thirty patients of both sexes,aged 21-59 yr,of American Society of Anesthesiologists physical status Ⅱ or Ⅲ (New York Heart Association Ⅱ or Ⅲ),with left ventricular ejection fraction ≥ 40％,scheduled for elective cardiac valve replacement under CPB,were divided into 2 groups (n=15 each) using a random number table:control group (C group) and ischemic postconditioning group (P group).In group P,ischemic postconditioning was induced by 3 cycles of 30 s aortic unclamping followed by 30 s cross-clamping starting from 5 min before complete opening of the ascending aorta.After induction of anesthesia and before operation (T1),at 1 h after opening of the ascending aorta (T2),at the end of operation (T3),and at 12,24 and 48 h after opening of the ascending aorta (T4-6),blood samples were taken from the radial artery for determination of plasma concentrations of heart-type fatty acid-binding protein (H-FABP),ischemia-modified albumin (IMA),and cardiac troponin Ⅰ (cTnI).Myocardial specimens in the right auricle were obtained at T2,and the pathological changes were examined using an optical microscope.Results The concentrations of plasma cTnI at T2-6 and H-FABP and IMA at T2-5 were significantly higher than those at T1 in the two groups (P＜0.05).Compared with group C,the concentrations of plasma cTnI at T2-6,H-FABP at T2-4,and IMA at T2,3 were significantly decreased (P＜0.05),and the pathological changes of myocardial tissues were significantly reduced in group P.Conclusion Ischemic postconditioning can reduce myocardial injury in the patients undergoing cardiac valve replacement under CPB.

Role of ultrasonic three -dimensional speckle tracking imaging in assessment left ventricular systolic function in patients with uremia before and after hemodialysis / 中国基层医药

Objective To assess the left ventricular global systolic function changes using ultrasonic three -dimensional speckle tracking imaging (3 D -STI )in patients with uremia undergoing high -flux hemodialysis (HFHD)treatment.Methods 86 patients with uremia and 59 healthy volunteers were selected.Participants of control group underwent plasma brain natrinuretic peptide(BNP)examinations before 3D -STI examinations.All the uremia patients received HFHD therapy,and underwent BNP and 3D -STI examinations before and after 4 weeks HFHD therapy.Parameters of left ventricular three dimensional global area strain(GAS),global circumferential strain (GCS),global longitudinal strain(GLS)and global radial strain(GRS)were measured in each group.The correlation between each 3D -STI parameters and BNP level were analyzed.Results Compared with the control group,GAS, GCS,GLS and GRS of left ventricular were significantly lower(t =7.564,6.866,7.946,5.477,all P <0.05)and BNP level in the control group were significantly higher in the uremia group[(60.75 ±17.22)ng/L vs.(792.68 ± 184.56)ng/L,t =30.876,P <0.05].After HFHD therapy 4 weeks,GAS,GCS,GLS and GRS of left ventricular were significantly higher(t =4.233,5.933,6.546,2.959,all P <0.05)and BNP level were lower(t =27.533,P <0.05) than before treatment in the uremia group.GAS,GCS,GLS and GRS of left ventricular were negatively correlated with BNP level(r =-0.51,0.64,-0.46,-0.43,all P <0.05).Conclusion 3D -STI can accurately evaluate the changes of left ventricular global systolic function in patients with uremia before and after hemodialysis,and provide reliable basis for clinical treatment and efficacy assessment.
