ABSTRACT

PURPOSE@#This study aimed at exploring the application of trauma time axis management in the treatment of severe trauma patients by using the Medicalsystem trauma system.@*METHODS@#We performed a retrospective cohort study involving patients with severe trauma. Patients who were admitted before the application of the Medicalsystem trauma system were divided into before system group; patients who were admitted after the application of the system were divided into after system group. Comparison was made between the two groups. For normally distributed data, means were reported along with standard deviation, and comparisons were made using the independent samples t test. Categorical data were compared using the Chi-square test. The Mann-Whitney U test was used to compare nonparametric variables.@*RESULTS@#There were 528 patients admitted to the study during the study period. There was no significant statistical difference in the time from the start of trauma team to arrive at the resuscitation room between the two groups. The time from arrival at hospital to endotracheal intubation, to ventilator therapy, to blood transfusion, to completion of CT scan, to completion of closed thoracic drainage, to the start of operation, as well as the length of stay in resuscitation room and hospital were significantly lower after the application of the Medicalsystem trauma system. The mortality was decreased by 8.6% in the after system group compared with that in the before system group, but there was no statistical difference.@*CONCLUSION@#The Medicalsystem trauma system can optimize diagnosis and treatment process for trauma patients, and accordingly improve the treatment efficiency and shorten the treatment time. Therefore, the Medicalsystem trauma system deserves further popularization and promotion.

ABSTRACT

Objective:To explore the clinical effect of combining kinesio taping with filtered infrared-A irradiation in the treatment of scapulohumeral periarthritis.Methods:Eighty-six patients with scapulohumeral periarthritis were randomly divided into a control group ( n=43) and an observation group ( n=43). Both groups received 20 minutes of irradiation with water-filtered infrared-A per day for 14 days, while the observation group was also given kinesio taping after the irradiation on 6 days of each week for the two weeks. Before and after the 2 weeks of treatment, both groups were evaluated for pain, their active and passive range of motion (AROM and PROM) of the shoulder, as well as the range of motion (ROM) of the shoulder joint, and their Constant-Murley score (CMS). The subjects also evaluated the functioning of their own shoulders using a visual analogue scale (VAS). Results:After the treatment, the average VAS scores of both groups were significantly higher than before the treatment, but the observation group′s average was significantly higher than that of the control group. There was significant improvement in the average AROM and PROM in both groups, but in the observation group the average AROM in anteflexion, rear protraction, abduction and extorsion and the average PROM in anteflexion and abduction were significantly better than the control group′s averages. The average total CMS scores of both groups had also improved significantly, but with significantly greater improvement in the observation group leading to a significant difference between the two groups after the intervention.Conclusions:Supplementing water-filtered infrared-A irradiation with kinesio taping is very effective in relieving pain, as well as improving ROM and life quality for persons with scapulohumeral periarthritis.

ABSTRACT

Objective:To investigate the safety and surgical treatment effect of da Vinci robot in male thyroid surgery.Methods:Clinical data of 276 male patients undergoing robotic thyroid surgery with bilateral axillo-breast approach (BABA) admitted to our hospital from Feb. 2014 to Jan. 2020 were retrospectively analyzed. They were compared with 372 male patients (open group) who had open surgery by the same team during the same time. Surgical time, the amount of fluid selitransteise after surgery, the length of hospitalization after surgery, the number of metastatic lymph node (for malignant tumor) , cosmetic effect satisfaction, injury of recurrent laryngeal nerve and decrease of parathyroid function and other related surgical complications were analyzed. SPSS 20.0 software was employed to carry out statistical analysis, the measurement data were compared with t-test, and the counting data were analyzed by χ2 test. Results:All operations were successfully completed and on one in the robot group was converted into open surgery. Compared with the open group, surgical time of the robot group (benign: 96.78±9.67min, malignant: 143.93±15.73min) was significantly longer than that of the open group (benign: 70.40±12.49min, malignant: 112.26±15.72min) ( P<0.05) , but the postoperative beauty effect of the robot group (benign: 9.62±0.33 points, malignant: 9.59±0.31 min) was better than that of the open group (benign: 5.33±0.37 points, malignant: 5.87±1.65 points) ( P<0.05) . In patients with pathological malignancy, the average age of the robot group (40.89±11.45 years) was lower than that of the open group (44.84±11.88 years) (P<0.05) . There was no significant difference in the amount of fluid induced after surgery, the length of hospital stay after surgery or the number of cases with lymph node metastasis in the two groups ( P>0.05) . There were 2 cases in the robot group and 5 cases in the open surgery group had recurrent metastasis in the side of the neck after surgery. None of the patients had permanent larynx reflux nerve damage or permanent parathyroid dysfunction. The average follow-up time was (25.36±16.13) months, ranging from 1 to 72 months. Conclusion:Compared with traditional open surgery, da Vinci robot surgery system is safe and feasible in male thyroid surgery, with better beauty effect, and provides new options for male thyroid surgery patients with neck beauty needs.

ABSTRACT

Objective:To investigate the effect of miRNA-618 (miR-618) on the cell proliferation and apoptosis of acute monocyte leukemia THP-1 cells.Methods:Real-time polymerase chain reaction (PCR) was used to detect the relative expression level of miR-618 in THP-1 cells and monocytes isolated from peripheral blood of the healthy people. Overexpression of miR-618 plasimid vector was constructed and empty vector was treated as the negative control; and then the two vectors were transfected with THP-1 cells; finally, miR-618 overexpression group and negative control group were set. THP-1 cell proliferation and apoptosis of both groups were detected by using CCK-8 method and flow cytometry, respectively. TargetScan was used to predict the target gene of miR-618 and it was verified by using luciferase reporter assay.Western blot was used to detect the protein levels of THP-1 cells in miR-618 overexpression group and negative control group, and predicted miR-618 target gene in peripheral blood monocytes of the healthy people.Results:PCR showed that the expression level of miR-618 was lower in THP-1 cells compared with that in monocytes isolated from peripheral blood of the healthy people ( P < 0.05). CCK-8 assay showed that compared with the negative control group, the proliferation ability of THP-1 cells in miR-618 overexpression group was decreased (the absorbance values at 0, 24, 48 and 72 h after transfection: 0.20±0.03 vs. 0.20±0.03, 0.28±0.02 vs. 0.35±0.03, 0.34±0.03 vs. 0.43±0.04, 0.39±0.02 vs. 0.53±0.05, all P < 0.05), and the late apoptosis rate was increased [(27.1±0.1)% vs. (14.9±0.1)%, t=2.13, P=0.03]. The target gene of miR-618 was ARPP19 predicted by using TargetScan software. Luciferase reporter assay showed that the relative luciferase activity of THP-1 cells in group transfected with wild-type ARPP19 gene plasmid+miR-618 gene plasmid was higher than that in the blank control group and group transfected with wild-type ARPP19 gene plasmid+miR-618 empty vector (0.170±0.003 vs. 0.100±0.004, 0.100±0.001, all P < 0.05). Western blot indicated the expression level of ARPP19 protein in THP-1 cells of miR-618 overexpression group was lower than that of the negative control group, while the expression levels of ARPP19 protein of peripheral blood monocytes of the healthy people in both groups were similar. Conclusion:miR-618 can inhibit the cell proliferation and promote apoptosis of THP-1 cells by inhibiting the expression of of THP-1 cells ARPP19 in acute monocyte leukemia.

ABSTRACT

Background@#Garlic oil is a rich source of organosulfur compounds including diallyl disulfide and diallyl trisulfide. There have been studies showing the neuroprotective actions of these organosulfur compounds. However, the potential of these organosulfur compounds in neuropathic pain has not been explored. The present study was aimed at investigating the pain attenuating potential of diallyl disulfide and diallyl trisulfide in chronic constriction injury (CCI)-induced neuropathic pain in rats. The study also explored their pain-attenuating mechanisms through modulation of H2S, brain-derived neurotrophin factor (BDNF) and nuclear factor erythroid 2-related factor 2 (Nrf2). @*Methods@#The rats were subjected to CCI injury by ligating the sciatic nerve in four places. The development of neuropathic pain was measured by assessing mechanical hyperalgesia (Randall–Selittotest), mechanical allodynia (Von Frey test), and cold allodynia (acetone drop test) on 14th day after surgery. @*Results@#Administration of diallyl disulfide (25 and 50 mg/kg) and diallyl trisulfide (20 and 40 mg/kg) for 14 days led to a significant reduction in pain in CCI-subjected rats. Moreover, treatment with these organosulfur compounds led to the restoration of H2S, BDNF and Nrf2 levels in the sciatic nerve and dorsal root ganglia. Coadministration of ANA-12 (BDNF blocker) abolished pain attenuating actions as well as BDNF and the Nrf2 restorative actions of diallyl disulfide and diallyl trisulfide, without modulating H2S levels. @*Conclusions@#Diallyl disulfide and diallyl trisulfide have the potential to attenuate neuropathic pain in CCI-subjected rats possibly through activation of H2S-BDNF-Nrf2 signaling pathway.

ABSTRACT

BACKGROUND: It is very difficult for urologists to choose what kind of substitute and how to reconstruct the long ureteral injuries to restore the integrity and function of the ureter. OBJECTIVE: To review recent progress and the evolution trends in the reconstruction methods of long ureteral injuries. METHODS: Relevant articles published from 1950 to 2019 were searched in PubMed, Web of Science, MEDLINE, and WanFang databases. The keywords were “ureteral injuries, ureteral replacement, biomaterial, tissue engineering, 3D bioprinting” in English and Chinese, respectively. The articles addressing ureteral replacement materials and reconstruction of ureteral injuries were selected. RESULTS AND CONCLUSION: In the reconstruction of long ureteral injury, the earliest repair method is to use autologous tissues, such as ileal, bladder muscle flap (Boari flap), and buccal mucosa graft. But such operations are difficult to avoid the damage to the surrounding tissues and organs. After that, various non-biomaterials were produced for ureteral replacement, but failed due to immune rejection and lack of peristalsis. With the development of cytology, biology and materials, the damaged tissues and organs have been regenerated by using autologous cells. Due to the development of regenerative medicine and three-dimensional printing technology, complex multi-component and multi-layered hollow tube structures that similar to their internal counterparts can be generated with three-dimensional bioprinting. But three-dimensional bioprinting cannot reconstruct the ureter and bladder with normal peristalsis and contraction function.

ABSTRACT

Objective:In comparison with full sternotomy, we explore the safety and clinical efficacy of upper hemisternotomy for Stanford A acute aortic dissection.Methods:Retrospective analysis of 78 patients with Stanford type A acute aortic dissection from January 2014 to December 2018(20 patients underwent UHS invasive, 58 patients underwent FS invasive). Based on variables including gender、age、BMI、LVEF、Euro SCORE Ⅱ and type of surgery, two matched cohorts including 18 patients respectively were constructed: group UHS and group FS, the baseline data and perioperative indicators were analyzed.Results:Operative mortality was 3.9%(3 of 78). The patients'baseline data were nearly balanced between the two groups after matching( P>0.05), only 1 case died of infectious cerebral hemorrhage in the FS group. The UHS group had a shorter cardiopulmonary bypass time than the FS group[(202±41)min vs.(235±39)min, P=0.041]. There was no significant difference in aorta clamping time[(159±38)min vs.(158±59)min, P=0.918] and hypothermic circulatory arrest time[(40±10)min vs.(50±20)min, P=0.081] between the two groups. The bladder temperature in the UHS group was significantly higher than that in the FS group[(24.0±3.1)℃ vs.(28.2±2.3)℃, P=0.001]. Compared with the FS group, the UHS group had less red blood cell transfusion[(4.8±2.8)U vs.(7.2±3.9)U, P=0.038], less postoperative drainage[(855±657)ml vs.(1510±703)ml, P=0.007], shorter ventilation support time(22 h vs. 58 h, P=0.037), shorter intensive care unit retention time[(4.6±2.7) days vs.(7.2±2.8) days, P=0.009], and shorter postoperative hospital stay time[(8.2±3.8) days vs.(18.4±3.8) days, P=0.001], but the incidence of pericardial puncture was higher in the UHS group[7(33%) vs. 1(6%), P=0.041]. 3 cases had postoperative renal insufficiency(requires dialysis), 5 cases(13.9%)had neurological complications, 1 case received re-exploration in the two groups respectively. Conclusion:The upper hemisternotomy approach is safe and feasible for Stanford A acute aortic dissection, with excellent early outcomes.

ABSTRACT

Objective:To report a case with frontotemporal dementia (FTD) characterized by involuntary laughter.Methods:The clinical manifestations and imaging characteristics of a patient diagnosed as FTD was analyzed. Then the results of cerebrospinal fluid, positron emission tomography-computed tomography (PET-CT) and single-photon emission computed tomography examinations were collected. Blood samples were tested for related genes of FTD.Results:The patient is a 66 years old woman with insidious onset and progressing symptoms and she was mainly manifested as laughing out loud involuntarily when looking at others, childishness, stubbornness, loss of interest, irritability and other personal changes. Mild motor and language disorders were also manifested as moving slowly and speaking unclearly. The magnetic resonance imaging showed the atrophy of bilateral frontal, temporal lobe and bilateral hippocampal while the image of PET-CT showed the metabolism was reduced in different degrees. Eventually, behavioural variant of FTD was diagnosed. The result of ANXA11 gene sequencing revealed the mutation of c.107C>G(p.P36R).Conclusions:This is the first case in which a heterozygous mutation of ANXA11 gene, which is related to amyotrophic lateral sclerosis (ALS), is found in simple FTD patient, suggesting that ANXA11 gene may play an important role in the pathogenesis of FTD. This further supports the theory that ALS and FTD are spectrum disorders.

ABSTRACT

Objective:To investigate the role of neutrophil extracellular traps (NETs) in psoriatic lesions in activation of absent in melanoma 2 (AIM2) inflammasomes in keratinocytes.Methods:Four skin specimens and 4 peripheral blood specimens were collected from patients with advanced psoriasis vulgaris, who were treated at Department of Dermatology, Xijing Hospital, the Fourth Military Medical University from January to December in 2018. In addition, 4 skin specimens were collected from healthy human controls, and 3 foreskin specimens from children aged under 15 years after circumcision. Tissue immunofluorescence study was performed to determine the expression of NETs and AIM2 inflammasomes in normal skin tissues and psoriatic lesions. Neutrophils were separated from peripheral blood of patients with psoriasis vulgaris by using magnetic beads, and NETs were extracted. Primary keratinocytes were isolated from foreskin tissues, and divided into 4 groups to be stimulated with phosphate-buffered saline (PBS) (control group) , NET extracts (NET group) , DNase Ⅰ-treated NET extracts (NET degradation group) or DNase Ⅰ (degrader control group) respectively for 48 hours. Western blot analysis was performed to determine the expression of AIM2 inflammasomes and its downstream molecules, and enzyme-linked immunosorbent assay (ELISA) to detect the level of IL-1β in the cell culture supernatant in the NET group and control group. Statistical analysis was carried out by using one-way analysis of variance and Dunnett- t test for multiple comparisons. Results:NET structures were observed in the epidermis of psoriatic lesions, but not in that of the healthy controls. Besides, the expression of AIM2 inflammasomes was higher in the epidermis of psoriatic lesions than in the healthy controls. Western blot analysis showed that there were significant differences in the protein expression of AIM2 and its downstream molecules pro-IL-1β and IL-1β among groups ( F = 23.80, 5.82, 15.64 respectively, all P < 0.001) . The NET group showed significantly higher protein expression of AIM2 (1.42 ± 0.03) , pro-IL-1β (1.32 ± 0.08) and IL-1β (1.40 ± 0.05) compared with the control group ( t = 15.14, 4.26, 8.71, respectively, all P < 0.05) , while no significant difference in the expression of AIM2, pro-IL-1β and IL-1β was observed between the NET degradation group (1.15 ± 0.07, 0.93 ± 0.03, 1.07 ± 0.05, respectively) and control group ( t = 2.10, 2.18, 1.40 respectively, all P > 0.05) . In addition, the IL-1β level in the cell culture supernatant was significantly higher in the NET group (13.15 ± 3.77 pg/ml) than in the control group (3.61 ± 0.20 pg/ml, t = 2.53, P < 0.05) . Conclusion:NETs exist in the epidermis of psoriatic lesions, can aggravate the inflammatory process in psoriasis, and contribute to the occurrence and development of psoriasis, likely by activating AIM2 and promoting the cleavage and secretion of IL-1β in keratinocytes.

ABSTRACT

The COVID-19 outbreak may have some impact on the use of biologics in psoriatic patients because immunosuppressive effects of biologics may potentially alter the susceptibility of patients to the virus, deteriorate the condition of infected patients or even change the prognosis of infection. According to currently available recommendations from international psoriasis academic organizations and specialists, as well as specific situation in China, the authors provide some guidance on the use of biologics for psoriatic patients undergoing or planning to undergo treatment with biologics, those with low or high risk of infection, and for those with or without COVID-19 infection, so as to provide references for clinical practice.
