ABSTRACT

3-iodothyronamine(T1AM)is an endog enous derivative of thyroid hormone. It can also be used as exogenous drug. It can play pharmacological effects such as reducing cardiac output and coronary flow ,slowing heart rate ,promoting lipolysis , reducing basic metabolism and improving learning and memory ability. Its regulatory effect on metabolism is similar to that of thyroxine,but regulatory effect on heart and thermogenic function is opposite to that of thyroxine. As a new chemical messenger , T1AM can exert different pharmacological effects through a variety of receptors and signal pathways. This review summarizes the research progress of various pharmacological effects and mechanisms of exogenous T 1AM,in order to provide new therapeutic drugs of cardiovascular ,metabolic diseases and nervous system diseases.

ABSTRACT

Objective:To observe the relationship between bone metabolism biochemical markers and clinic features in patients with spinal cord injury. Methods:From July, 2018 to December, 2019, totally 135 patients with spinal cord injury were enrolled. They were assessed with American Spinal Injury Association Impairment Scale (AIS). β-collagen type I C-terminal telopeptide (β-CTX), total N-terminal propeptide of type I precollagen (TP1NP), 25-hydroxyvitamin D [25(OH)D] and parathyroid hormone (PTH), serum calcium and serum phosphorus were measured. The level of TP1NP, β-CTX, 25(OH)D and PTH among clinical characteristics (gender, age, disease course, AIS grade and so on) were analyzed. Results:The levels of β-CTX and 25(OH)D were lower in women than in men (|t| > 2.044, P < 0.01). There was difference in the level of 25(OH)D among different ages (F = 3.156, P < 0.05). The levels of β-CTX and TP1NP increased in the first four months after spinal cord injury, and decreased then; while the level of PTH decreased in the first four months, and increased then (P < 0.001). The level of β-CTX was lower in patients of AIS D than in patients of AIS A and C (t >2.679, P < 0.05). The level of TP1NP was higher in paraplegics than in quadriplegics (Z = -2.035, P < 0.05). The level of β-CTX was higher in patients with fractures or surgeries involving bone than in patients without fractures or surgeries involving bone (t = 2.169, P < 0.05). There was no difference in all the bone metabolism markers between patients with and without lower extremity motor function (t < 0.839, Z < 1.822, P > 0.05). The ratio of 25(OH)D deficience was 85.19%. Conclusion:Bone conversion was active in the first four months after spinal cord injury, and decreased gradually then, which may be related to fractures of spine or surgeries involving spine after injury. The effect of spinal cord injury on bone metabolism markers is not clear. Most of patients with spinal cord injury were lack of vitamin D.

ABSTRACT

Objective:To investigate the occurrence and related factors of autonomic dysreflexia (AD) during intermittent catheterization in patients with spinal cord injury (SCI). Methods:Case control study was used in this study. Intermittent catheterization was performed on 44 SCI patients hospitalized from April, 2019 to April, 2020, The data of age, gender, time after injury, segment of injury, degree of injury, resting blood pressure, immediate blood pressure after catheterization, catheterization numbers, catheterization volume and duration of catheterization were collected. Descriptive analysis and binary Logistic regression analysis were used to analyze the occurrence and related factors of AD. Results:Totally, AD happened in 26 (59.1%) patients. Urethral catheterization was done 1738 times, out of which AD accounted for 187 times (10.8%). The risk of AD increased with the time after injury and age (P < 0.05). The probability of AD was lower in T7 SCI and below than in T6 SCI and above (P = 0.002). Catheterization numbers, gender, degree of injury, catheterization volume and duration of catheterization were not influencing factors of AD (P > 0.05). Conclusion:It is necessary to have a full understanding for the occurrence of AD in patients with SCI during intermittent catheterization. For patients with SCI in T6 and above, long time after injury and elderly patients, routine monitoring of blood pressure during intermittent catheterization is recommended to detect and deal with AD in time.

ABSTRACT

Objective:To explore the clinical manifestations and MRI features of pediatric spinal cord injury (SCI) after back bend. Methods:A retrospective study was performed. All the medical records and MRI images of children with SCI after back bend were identified in Beijing Bo'ai Hospital from January 1st, 2002 to August 31st, 2020. Results:A total of 120 SCI children after back bend were reviewed, out of whom 119 cases were girls, one case was boy. The age ranged from 38 to 162 months, with the median age of 76 months. More cases were discovered in July and September every year (32 cases, 26.7%), as well as in weekends (67 cases, 55.8%). The main clinical manifestations were sensory and motor dysfunction of both lower limbs (120 cases, 100%), bladder and bowl incontinence (120 cases, 100%). The common first symptoms included sudden attack of lumbar pain (39 cases, 32.5%), lower limbs paralysis (30cases, 25.0%) and leg pain (10 cases, 8.3%). The peak time of symptoms ranged from five minutes to two days, with the median time of 50 minutes. The MRI features of 104 children with SCI within one week after back bend were as follows: the abnormal signals of MRI in spinal cord involved lower cervical and all the following segments of spinal cord. The number of the segments of spinal cord with abnormal signals ranged from two to 15, with the median of seven segments. The most common segments with abnormal signals were T9 (96 cases, 92.3%), T10 (96 cases, 92.3%) and T11 (90 cases, 86.5%). Among the cases followed up, 48 cases with complete injury demonstrated a vast and serous spinal cord atrophy (SCA) below the injury segments as early as 37 days after the injury, the SCA would become worse at the chronic stage and maybe involve the spinal cord above the injury segments. In 31 cases with incomplete injury, the abnormal signals of MRI in spinal cord were limited in the lumbar enlargement, with a various degree of SCA at the late stage. All the cases were diagnosed as SCI without radiologic abnormality, out of whom 89 (74.2%) cases suffered from thoracic complete SCI, 31 (25.8%) cases suffered thoracic or lumbar incomplete SCI. The common complications included scoliosis, hip joint dysplasia, urinary tract infection, hydronephrosis, osteoporosis, pathological fracture of lower limbs and valgus knee. Conclusion:The main clinical symptoms of pediatric SCI after back bend were sudden lumbar pain, sensory and motor dysfunction of both lower limbs, and bladder and bowl incontinence. Most of the cases were thoracic complete SCI, the MRI features at the early stage were multiple segments of abnormal signals of spinal cord around T9 and T10, and later an extensive severe SCA below the injury segments to the conus medullaris, accompanied by the SCA above the injury segments.

ABSTRACT

Objective:To investigate the outcome of neurological function and the clinical characteristics of complications in children with spinal cord injury. Methods:From 2011 to 2019, children under 15 years old with spinal cord injury were selected in our hospital. Their level of injury and American Spinal Injury Association Impairment Scale (AIS) at one month, three months and one year were recorded. And the complications such as pressure ulcers/scald, urinary tract infection, hydronephrosis/vesicoureteral reflux, constipation, osteoporosis/fracture, deep vein thrombosis, neurodynia, heterotopic ossification, scoliosis and hip dysplasia were analyzed. Results:Of 159 individuals, 41 were boys and 118 were girls, the average age at injury was (6.08±2.57) years. The main cause of spinal cord injury was sports accidents (47.8%), and the main injury sites were thoracic spinal cord injury (89.3%). The cause of spinal cord injury was correlated with age at injury (r = -0.160, P = 0.044), gender (r = -0.458, P < 0.001) and injury sites (r = -0.249, P = 0.002). Complete spinal cord injury counted for 71.7%, and the AIS grade at one month was correlated with that at twelve months (r = 0.984, P < 0.001). The main complications were urinary tract infection (69.2%), constipation (67.9%), hydronephrosis/vesicoureteral reflux (37.7%), scoliosis (25.8%) and hip dysplasia (25.2%). The incidence of ulcers/scald was correlated with injury site (r = 0.179, P = 0.024). The AIS grade three months after injury was significantly correlated with urinary tract infection, constipation, scoliosis and hip dysplasia (|r| > 0.227, P < 0.01). The incidence of ulcers/scald was correlated with osteoporosis/fracture (r = 0.208, P < 0.01). The incidence of urinary tract infection was significantly correlated with hydronephrosis/vesicoureteral reflux, constipation, scoliosis and hip dysplasia (r > 0.261, P < 0.001), as well as osteoporosis/fracture (r = 0.195, P < 0.05). The incidence of hydronephrosis/vesicoureteral reflux was significantly correlated with constipation, osteoporosis/fracture, scoliosis and hip dysplasia (r > 0.146, P < 0.01). The incidence of constipation was significantly correlated with scoliosis and hip dysplasia (r > 0.313, P < 0.01), as well as osteoporosis/fracture (r = 0.160, P < 0.05). The incidence of osteoporosis/fracture was significantly correlated with scoliosis and hip dysplasia (r > 0.342, P < 0.01). The incidence of scoliosis was significantly correlated with hip dysplasia (r = 0.818, P < 0.001). Conclusion:The recovery of neurological function after spinal cord injury in children is closely correlated to AIS. The outcome of complete spinal cord injury is poor. The common complications after spinal cord injury in children demonstrate specific age characteristics, and the incidence of urinary tract infection, constipation, hydronephrosis/vesicoureteral reflux, scoliosis and hip dysplasia are common complications, which need more attention.

ABSTRACT

Objective:To investigate the clinical characteristics of old patients with spinal cord injury. Methods:From January 1, 2013 to December 31, 2019, totally 386 old (≥ 60 years) patients with spinal cord injury were enrolled. Their gender, age, etiology, American Spinal Injury Association Impairment Scale (AIS) and complications were analyzed. Results:In the old patients with spinal cord injury, traumatic spinal cord injury was more common in males (71.17%) and non-traumatic spinal cord injury was more common in females (56.19%). Fall on level surface was the most important cause of spinal cord injury both in old men (28.83%) and women (24.76%). Tumor (19.05%) was the most common non-traumatic cause of spinal cord injury in old female patients. Cervical segment (78.46%) was the most common site of injury in old traumatic spinal cord injury, while thoracic segment (52.14%) was the most common site of injury in non-traumatic spinal cord injury. Grade D (38.08%) was the most common AIS grade, followed by grades C (28.76%), A (21.50%), and B (11.66%). Spinal canal stenosis (23.31%) played an important role in the etiology of old spinal cord injury. Neuralgia, venous thrombosis of lower extremities and urinary tract infection were the most common complications in old patients with spinal cord injury. Conclusion:Fall on level surface is the leading cause of spinal cord injury in old patients, and the proportion of fall in the etiology of old spinal cord injury tends to increase with age. It is important to take effective measures to avoid falling in the old adults to prevent spinal cord injury.

ABSTRACT

Objective:To explore the relationship between ventilator-associated pneumonia (VAP) and neutrophil/lymphocyte ratio (NLR) before mechanical ventilation in patients with malignant tumors.Methods:A retrospective nested case-control study was conducted. Patients with malignant tumor treated by mechanical ventilation admitted to the Third Affiliated Hospital of Guizhou Medical University from February 2015 to February 2020 were enrolled. The patients with VAP were selected as the case group, and the matched non-VAP cases were selected according to 1∶2 as the control group. The clinical data were collected, and the differences of each index between the two groups were compared. The influencing factors of VAP in patients with malignant tumor were analyzed by multivariate Logistic regression.Results:During the study period, 1 271 patients with malignant tumors were treated with mechanical ventilation, of which 241 cases had VAP, and the incidence of VAP was 18.96%. There were 232 VAP patients in the case group matched 464 non-VAP patients in the control group. The clinical data of age, gender, hospitalization diagnosis, primary tumor, regional lymph node and distant metastasis (TNM) stage, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ), complications, duration of mechanical ventilation, hemoglobin (Hb) and serum albumin (Alb) levels were balanced and comparable between the two groups, and the cluster nursing measures were consistent. Compared with the control group, although there was no significant difference in neutrophil count (NEU) and lymphocyte count (LYM) in the case group [NEU (×10 9/L): 3.81±1.07 vs. 3.64±1.05, LYM (×10 9/L): 2.06±0.59 vs. 2.15±0.62, both P > 0.05], NLR was significantly increased (2.07±1.05 vs. 1.89±0.96, P < 0.05), and the hospital stay was significantly longer (days: 24.84±3.81 vs. 13.19±3.98, P < 0.01). NLR, gender, age, APACHEⅡ score, TNM stage, Hb, serum Alb and duration of mechanical ventilation were included in multivariate Logistic regression analysis. The results showed that patients with elevated NLR had higher risk of VAP [odds ratio ( OR) = 1.187, 95% confidence interval (95% CI) was 1.015-1.387, P = 0.032]. In patients with VAP, NLR was negatively correlated with the time of mechanical ventilation before VAP (r = -0.327, P = 0.000), and positively correlated with the time of treatment with antibiotics after VAP (r = 0.559, P = 0.000). Conclusion:Elevated NLR in patients with malignant tumors who were on mechanical ventilation can significantly increase the risk of VAP and increase the difficulty of treatment.

ABSTRACT

Objective:To compare the short-term efficacy of Billroth Ⅱ+Braun anasto-mosis versus Roux-en-Y anastomosis in totally three-dimensional (3D) laparoscopic distal gastrectomy.Methods:The retrospective cohort study was conducted. The clinicopathological data of 140 patients with gastric cancer who were admitted to the First Medical Center of Chinese PLA General Hospital from January 2016 to January 2020 were collected. There were 105 males and 35 females, aged from 23 to 84 years, with a median age of 55 years. Of the 140 patients, 54 patients undergoing totally 3D laparoscopic distal gastrectomy with Billroth Ⅱ+Braun anastomosis were allocated into Billroth Ⅱ+Braun group, and 86 patients undergoing totally 3D laparoscopic distal gastrectomy with Roux-en-Y anastomosis were allocated into Roux-en-Y group, respectively. Observation indicators: (1) surgical situations; (2) postoperative situations; (3) follow-up. Follow-up using outpatient examination and telephone interview was conducted to detect remnant gastritis and its severity, bile reflux, reflux esophagitis in the postoperative 3 months up to April 2020. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the t test. Count data were described as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test or Fisher exact probability. Comparison of ordinal data was analyzed using the Mann-Whitney U test. Results:(1) Surgical situations: 140 patients underwent totally 3D laparoscopic distal gastrectomy. The operation time, cases with volume of intraoperative blood loss <50 mL, 50 to 200 mL or >200 mL, the number of lymph node dissected were (233±39)minutes,15, 35, 4, 30±13 for the Billroth Ⅱ +Braun group , respectively, versus (240±52)minutes,25, 51, 10, 27±10 for the Roux-en-Y group, showing no significant difference between the two groups ( t=0.856, χ2=0.774, t=1.518, P>0.05). (2) Postoperative situations: cases with drainage tube, time to postoperative first flatus, cases with postoperative grade Ⅱ, Ⅲ, Ⅳ, Ⅴ complications, cases with postoperative complications, cases with postoperative severe complications, duration of postoperative hospital stay, surgery cost and total hospitalization cost of the Billroth Ⅱ+Braun group were 38, (3.5±0.8)days,4, 1, 0, 0, 5, 1, (9.0±5.0)days, (3.8±1.2)×10 4 yuan and (9.7±2.1)×10 4 yuan, respectively. The above indicators of the Roux-en-Y group were 59, (3.7±1.0)days, 9, 1, 0, 1, 11, 2, (9.0±4.0)days, (4.3±1.0)×10 4 yuan and (9.2±2.1)×10 4 yuan, respectively. There was a significant difference in the surgery cost between the two groups ( t=2.453, P<0.05), while there was no significant difference in cases with drainage tube, time to postoperative first flatus, cases with postoperative grade Ⅱ, Ⅲ, Ⅳ, Ⅴ complications, cases with postoperative complications, duration of postoperative hospital stay or total hospitalization cost between the two groups ( χ2=0.049, t=?1.339, Z=0.000, χ2=0.409, t=0.197, 1.383, P>0.05). There was also no significant difference in cases with postoperative severe complications between the two groups ( P>0.05).(3) Follow-up: 134 of 140 patients received the follow-up, including 52 cases in the Billroth Ⅱ+Braun group and 82 cases in the Roux-en-Y group. Results of follow-up within postoperative 3 months showed that the incidence rates of remnant gastritis, bile reflux, reflux esophagitis were 61.5%(32/52), 38.5%(20/52), 26.9%(14/52) for the Billroth Ⅱ+Braun group, respectively, versus 41.5%(34/82), 22.0%(18/82), 12.2%(10/82) for the Roux-en-Y group, showing significant differences between the two groups ( χ2=5.131, 4.270, 4.695, P<0.05). Cases with grade 0,Ⅰ,Ⅱ, Ⅲ, Ⅳ residual food were 42, 3, 5, 2,0 for the Billroth Ⅱ+Braun group, versus 67, 9, 1, 5,0 for the Roux-en-Y group, showing no significant difference between the two groups ( Z=?0.156, P>0.05). Cases with minimal lesion, grade A, grade B gastritis (severity of gastritis) were 6, 5, 3 for the Billroth Ⅱ+Braun group, versus 8, 2, 0 for the Roux-en-Y group, showing no significant difference between the two groups ( Z=?1.468, P>0.05). Conclusions:It is safe and feasible to operate Billroth Ⅱ+Braun or Roux-en-Y anastomosis in totally 3D laparoscopic distal gastrectomy. Billroth Ⅱ+Braun anastomosis can reduce the surgical cost. Roux-en-Y anastomosis has advantages in reducing the incidence of reflux esophagitis, bile reflux and reflux gastritis.

ABSTRACT

Objective:To optimize the topological design of locking plate for distal radial fracture so that the internal fixation stiffness can be customized.Methods:Models of both the distal radial fracture and the conventional locking plate fixation were constructed using software for three-dimensional modeling and computer-aided design. Based on the data from our previous finite element analysis, a decrease of 33.33% in axial stiffness but retention of more than 90.00% in torsional stiffness were defined as the optimization limits. The conventional plate was redesigned by way of topological optimization iterations. Finite element analysis was done to compare stiffness and interfragmentary strain (IFS) between the new optimized design and conventional design of the locking plate under both compressive and torsional loads.Results:The axial stiffness of the optimized plate was 636.5 N/mm with a downgrading magnitude of 19.7% which was close to the given limit; the torsional stiffness was 634.12 Nmm/° with a downgrading magnitude of 8.8% which remained under the given limit. In the optimized design, a more significant increase was observed in axial IFS than that in shear IFS, leading to a similar effect as the stiffness regulation did.Conclusion:The optimized design of locking plate for distal radial fracture can provide a reliable solution for customized regulation of the internal fixation stiffness.

ABSTRACT

Objective:To explore the etiological features and prevention strategies for pediatric spinal cord injury (SCI). Methods:A retrospective study of etiology and demographics features was performed and all the children with SCI (less than 14 years old) were identified in our hospital from January 1st, 2015 to December 31st, 2019. Results:A total of 221 children with SCI were reviewed, with 62 boys and 159 girls. The age ranged from one to 13 years with the median age of six years old. Children aged four to seven years accounted most (55.7%), and were mainly girls (83.7%). Sports and leisure activities (78 cases, 35.3%), non-traumatic causes (56 cases, 25.3%), other traumatic causes (48 cases, 21.7%), transport activities (24 cases, 10.9%) and falling from height (12 cases, 5.4%) were the top five leading causes of pediatric SCI. Among the cases caused by sports and leisure activities, 96.2% (75/78) were related to back bend in dancing exercise, in which most were five to seven years old (80.0%), and all of them were thoracic cord injury without radiologic abnormality, in which 70.7% (53/75) suffered from complete SCI. Conclusion:Pediatric SCI after back bend in dancing exercise is increasing rapidly in recent years. More attention should be paid on education about professional evaluation and the risk of back bend before dancing exercise, and more protective measures should be implemented.

ABSTRACT

Objective@#To investigate the surgical options for splenic lymph node dissection in patients with advanced gastric cancer undergoing radical total gastrectomy, and to evaluate the sentinel effect of No. 4s lymph node on splenic lymph node metastasis.@*Methods@#A prospective, single-center, randomized and controlled study was carried out (Trial registration, No.NCT02980861). Enrollment criteria: (1) >18 years old and <65 years old; (2) gastric adenocarcinoma locating in the proximal or corpus; (3) preoperative clinical staging as cT2-4aN0-3M0; (4) D2 radical total gastrectomy feasible judged before operation; (5) physical ability score 0 to 1; (6) I to III of ASA classification. Pregnant or lactating women, patients with severe mental illness or previous history of upper abdominal surgery, those suffered from other malignant tumors in the past 5 years, or heart and lung system diseases judged to affect surgery before operation, those receiving preoperative chemotherapy, radiotherapy or targeted therapies, and distant metastases being found during surgery were excluded. According to above criteria, 222 patients at The First Medical Center of Chinese PLA General Hospital from December 2016 to December 2017 were enrolled prospectively and were randomly divided into the laparoscopic splenic hilar lymph node dissection group (laparoscopic group, n=114) and the open splenic hilar lymph node dissection group (open group, n=108). The result of rapid frozen immunohistochemistry of harvested No.4s lymph nodes was used to evaluate the sensitivity and specificity of sentinel effect on splenic hilar lymph node metastasis. The surgical parameters, postoperative recovery parameters, and complication rates were compared between the two groups.@*Results@#There were 80 males and 34 females in the lapascopic group with a mean age of (56.1±10.2) years, and 69 males and 39 females in the open group with a mean age of (58.4±10.9) years. There were no significant differences in baseline data between the two groups (all P>0.05). Total blood loss was less in the laparoscopic group [(96.3±82.4) ml vs. (116.6±101.9) ml, t=1.124, P<0.001], and the amount of bleeding from the splenic hilar lymph nodes dissected was also less than that in the open group [(25.3±17.8) ml vs. (59.5±36.4) ml, t=1.172, P<0.001]. However, the operation time, the time of splenic hilar lymph node, the number of lymph node dissected and number of splenic hilar lymph node dissected were not significantly different between the two groups (all P>0.05). As compared to the open group, the laparoscopic group had shorter time to the first flatus [(1.3±1.2) days vs. (1.6±1.5) days, t=1.665, P=0.021], shorter time to fluid diet [(4.6±1.4) days vs. (4.9 ± 1.6) days, t=1.436, P=0.007], shorter time to remove nasogastric tube [(3.9±2.6) days vs. (4.3±2.4) days, t=0.687, P<0.001] and shorter hospital stay [(10.3±6.6) days vs. (12.1±7.2) days, t=0.697, P<0.001]. Complication rate was 14.0% (16/114) and 12.0% (13/108) in the laparoscopic group and the open group, respectively, without significant difference (χ2=6.723, P=0.331). The sensitivity of the No. 4s lymph node for the prediction of splenic hilar lymph node metastasis reached 89.5%, and the specificity reached 99.6%.@*Conclusions@#Laparoscopic technique is safe and feasible in the treatment of splenic hilar lymph node dissection in advanced gastric cancer. The No.4s lymph node examination has good sentinel effect on predicting the metastasis of splenic hilar lymph nodes.

ABSTRACT

Objective@#To investigate clinicopathological features and prognostic factors of gastric neuroendocrine tumors (G-NEN).@*Methods@#Clinical and pathological data of patients with G-NEN diagnosed by pathological examination in Chinese PLA General Hospital from January 2000 to June 2018 were retrospectively analyzed in this case-control study. Patients with complicated visceral lesions, other visceral primary tumors, mental disorders and incomplete clinicopathological data were excluded. Finally, 240 hospitalized patients who met the inclusion criteria were enrolled. Physical examination information, tumor characteristics and pathological characteristics of patients were summarized. The Cox regression models were used to analyze the risk factors affecting G-NEN and the survival conditions were described by Kaplan-Meier survival curves and log-rank test.@*Results@#In 240 patients with G-NEN, the mean age was (60.3±10.1) years; 181 were male (75.4%) and 59 females (24.6%); mean tumor diameter was (4.2±2.8) cm; 51 cases (21.2%) were neuroendocrine tumor (NET), 139 cases (57.9%) neuroendocrine carcinoma (NEC), 50 cases (20.8%) mixed neuroendocrine carcinoma (MANEC); 28 cases (11.7%) were G1 low grades, 34 cases (14.2%) G2 medium grades, and 178 cases (74.2%) G3 high grades; tumor infiltration depth T1 to T4 were 44 cases (18.3%), 27 cases (11.2%), 60 cases (25.0%) and 109 cases (45.4%) respectively; 163 cases (67.9%) developed lymphatic metastasis and 46 patients (19.2%) distant metastasis; tumor stage from stage I to stage IV were 55 cases (22.9%), 42 cases (17.5%), 94 cases (39.2%) and 53 cases (22.1%) respectively. Of the 240 G-NEN patients, 223 cases (92.9%) were followed up. The median survival time of the patients was 39.2 (95% CI: 29.1 to 47.5) months. Univariate survival analysis showed that age ≥ 60 years, tumor diameter ≥ 4.2 cm, tumor grade G3, lymphatic metastasis, distant metastasis, and tumor stage III-IV were risk factors for G-NEN patients. Multivariate survival analysis revealed that lymphatic metastasis (HR=1.783, 95%CI: 1.007-3.155, P=0.047) and distant metastasis (HR=2.288, 95% CI: 1.307-4.008, P=0.004) were independent risk factors of the prognosis. Further analysis of the G3 subgroup of G-NEN showed that the 5-year survival rate of NET-G3 was 76.19%, which was significantly higher than that of NEC-G3 and MANEC-G3 (15.60% and 24.73%, P=0.012).@*Conclusions@#Most G-NEN patients are in advanced stage at diagnosis. Lymphatic metastasis and distant metastasis indicate poor prognosis. The prognosis of high proliferation NET-G3 patients is better as compared to those of NEC-G3 and MANEC-G3. This classification is worth further attention.

ABSTRACT

Objective To investigate epidemiological characteristics of measles cases and the influencing factors of transmission of measles among floating children in Shenzhen. Methods Descriptive study was conducted in data which were collected from the report system of statutory infectious diseases from 2016 to 2018 in Shenzhen. Case-control study was conducted between 89 cases and relative controls. Results A total of 108 measles cases in floating children were reported from 2016 to 2018, and the incidence trend showed a year-on-year decline( 2trend=68.35, P<0.001). Analysis showed that nosocomial exposure in 7 to 21 days ago(OR=7.80, 95% CI:3.51-17.35, P<0.001), having been to the crowded places(OR=3.37, 95% CI:1.52-7.47, P=0.002), having contact history of fever-rash patients(OR=4.57, 95% CI:1.41-14.84, P=0.007) were influencing factors of transmission of measles among floating children, and immunization at the prescribed time(OR=0.12, 95% CI:0.04-0.32, P<0.001) was a protective factor for measles. Conclusions Vaccination must be strengthened for floating children. Medical institutions should avoid becoming a key place for measles transmission, and need to strengthen health education.

ABSTRACT

Objective To explore the dynamic characteristics of the thoracolumbar osteoporotic vertebral bodies under free state. Methods Based on CT data from the thoracic and lumbar vertebral body of a healthy female volunteer, model materialization and intervertebral disc tissue reconstruction were realized by using the computerized processing software. The finite element models of normal thoracolumbar vertebral body and thoracolumbar osteoporotic vertebral body were established in ABAQUS 6.14 to perform modal analysis. Results Compared with the normal model, the osteoporosis model had a lower natural frequency and a lager amplitude. As the vibration frequency increased, the model vibration type changed from uniaxial and unidirectional motion to multiaxial and multidirectional motion, and the responsible vertebral body for the maximum amplitude moved down gradually. Conclusions Modal analysis can better analyze dynamic characteristics of the thoracolumbar osteoporotic vertebral body. Patients with osteoporosis should try to avoid the specific vibration environment, so as to decrease the risk of intervertebral disc tissue degeneration, strain of thoracolumbar soft tissues and lesion in posterior structures of the vertebral body.

ABSTRACT

To investigate the risk factors associated with acute renal failure (ARF) after thoracoabdominal aortic aneurysm (TAAA) surgery. A total of 156 patients underwent TAAA repair between January 2009 and December 2017. Renal failure was defined based on the Kidney Disease Improving Global Outcomes criteria. The patients were divided into ARF group and non-ARF group based on the presence/absence of postoperative ARF. The risk factors of ARF were analyzed by univariate analysis and multivariate logistic analysis. The subjects included 111 males and 45 females aged (40.4±10.9) years (range:19-65 years). The surgical reasons included aortic dissection (=130,83.3%),aneurysm (=22,14.1%),and pseudoaneurysm (=4,2.6%). The degrees of repair included Crawford extent I in 6 patients (3.8%),extent Ⅱ in 128 patients (82.1%),extent Ⅲ in 20 patients (12.8%),and extent Ⅳ in 2 patients(1.3%). There were 3 patients presented with aortic rupture and 6 patients received emergent operations. Nine patients (5.8%) died within 30 days after surgery,and 8 patients (5.1%) suffered from permanent paraplegia. Thirty-six patients (23.1%) had ARF after surgery,and 18 of them needed dialysis. Multivariate logistic analysis showed that smoking ( =2.637,95%=1.113-6.250,=0.028),packed red blood cell usage in operation (≥6 U) ( =5.508,95%=2.144-11.930,=0.000),reoperation for bleeding (=3.529,95%=1.298-9.590,=0.013) were independent risk factors for ARF after TAAA repair. Smoking,packed red blood cell usage in operation (≥6 U),reoperation for bleeding are the independent risk factors of ARF after TAAA surgery.

ABSTRACT

To evaluate the early and mid-term results after surgical repair of thoracoabdominal aortic aneurysm(TAAA)in patients with DeBakey typeⅠor Ⅲ aortic dissection. The clinical data of 130 patients who underwent TAAA repair for chronic DeBakey typeⅠ(groupⅠ, =47)or type Ⅲ(group Ⅲ, =83)aortic dissections in our center between January 2009 and December 2017 were retrospectively analyzed.Early postoperative results,midterm survival,and re-interventions were compared between these two groups. The 30-day mortality rate was 6.9%(=9)in the overall cohort,with no statistic difference between groupⅠand group Ⅲ(10.6% 4.8%;=0.803, =0.370).The incidence of major adverse events(38.3% 51.8%;=2.199, =0.138),5-year actuarial survival rate [(81.7±5.9)% (87.2±4.2)%;=0.483, =0.487],and 5-year actuarial freedom from all reinterventions [(84.5±6.7)% (85.5±4.8)%;=0.010, =0.920] showed no significant differences between these two groups. The early and mid-term outcomes after surgical repair of TAAA are similar for DeBakey typeⅠ and type Ⅲ patients.However,studies with larger sample sizes are still required.
