ABSTRACT

OBJECTIVE@#To explore the effect of intermittent pneumatic compression(IPC) combined with 3M thermometer on the prevention of deep venous thrombosis(DVT) in patients with femoral intertrochanteric fracture.@*METHODS@#From March 2016 to August 2019, 127 patients with femoral intertrochanteric fractures who underwent proximal femoral nail antirotation(PFNA) were retrospectively analyzed. They were divided into two groups according to different methods of thrombus prevention and treatment. Among them, 63 patients in group A did not use IPC and 3M thermometer;64 cases in group B were treated with IPC combined with 3M thermometer. Color Doppler ultrasound was used to dynamically monitor the DVT and changes of lower limbs during perioperative period. The venous thrombosis of lower limbs was monitored at 0, 24, 72 h and > 72 h after operation(recheck every 3 days until discharge).@*RESULTS@#Occurrence of DVT of lower limbs after PFNA operation in two groups:there were 5 cases (7.8%) in group B and 20 cases (31.7%) in group A, there was significant difference between two groups (P=0.001). There was no significant difference in lower limb DVT between two groups at 0, 72 and > 72 h after operation(P>0.05), but the formation rate of group A was significantly higher than that of group B at 24 h after operation (P=0.049). There was no significant difference in DVT formation between group A and group B(P>0.05). However, the formation of DVT in group A was significantly higher than that in group B(P=0.012).@*CONCLUSION@#Intraoperative IPC combined with 3M thermostat can effectively prevent DVT of lower limbs in patients undergoing PFNA surgery.

ABSTRACT

Objective:To investigate the protective effect of Naoxin'an capsule (NC) against glial cell activation and inflammatory damage in brain of rats with chronic cerebral hypoperfusion-induced vascular cognitive impairment (VCI). Method:One hundred and fifty rats were randomly divided into a sham operation group (<italic>n</italic>=20) and a modeling group (<italic>n</italic>=130). Following the modeling with the two vessels occlusion (2-VO) technique, 87 successfully modeled rats were randomly divided into the model group, positive drug group (aricept, 0.5 mg·kg<sup>-1</sup>), and low-, medium-, and high-dose (0.18, 0.36, 0.72 g·kg<sup>-1</sup>) NC groups, with 17-18 rats in each group. After intragastric administration of NC for eight weeks, the Morris water maze test and passive avoidance test were conducted to detect the effects of NC on learning and memory ability of VCI rats. Changes in neuronal structure of rat hippocampal CA1 area were observed by hematoxylin-eosin (HE) staining, and the neuronal apoptosis in hippocampus by terminal deoxynucleotidyl transferase (TdT)-mediated dUTP nick end labeling (TUNEL) staining. Western blot assay was used to detect the expression levels of glial fibrillary acidic protein (GFAP), ionized calcium-binding adapter molecule 1 (Iba-1), phosphorylated p38 mitogen-activated protein kinase (p38 MAPK), and phosphorylated nuclear factor <italic>κ</italic>B (NF-<italic>κ</italic>B), followed by the measurement of interleukin-1<italic>β</italic> (IL-1<italic>β</italic>) and tumor necrosis factor-<italic>α</italic> (TNF-<italic>α</italic>) in the brain by enzyme-linked immunosorbent assay (ELISA). Result:Compared with the sham operation group, the model group displayed obviously decreased spatial learning and memory ability and memory retention ability (<italic>P</italic><0.05, <italic>P</italic><0.01), neuronal damage in hippocampal CA1 area, enhanced neuronal apoptosis (<italic>P</italic><0.01), up-regulated GFAP and Iba-1 (<italic>P</italic><0.01), elevated phosphorylation of p38 MAPK and NF-<italic>κ</italic>B (<italic>P</italic><0.01), and increased IL-1<italic>β</italic> and TNF-<italic>α</italic> (<italic>P</italic><0.01). Compared with the model group, NC at each dose significantly improved the spatial learning and memory ability and memory retention ability of VCI rats (<italic>P</italic><0.05, <italic>P</italic><0.01), ameliorated the neuronal damage in hippocampus CA1 area, reduced the apoptosis rate of nerve cells (<italic>P</italic><0.05, <italic>P</italic><0.01), down-regulated the expression of GFAP and Iba-1 (<italic>P</italic><0.01), decreased the phosphorylation levels of p38 MAPK and NF-<italic>κ</italic>B (<italic>P</italic><0.05, <italic>P</italic><0.01), and lowered TNF-<italic>α</italic> and IL-1<italic>β</italic> levels (<italic>P</italic><0.01). Conclusion:NC alleviates the inflammatory damage of the central nervous system caused by activated p38 MAPK and NF-<italic>κ</italic>B and improves chronic cerebral hypoperfusion-induced VCI in rats by inhibiting the activation of microglia and astrocytes.

ABSTRACT

BACKGROUND@#Postural tachycardia syndrome (POTS) is a common childhood disease that seriously affects the patient's physical and mental health. This study aimed to investigate whether pre-treatment baseline left ventricular ejection fraction (LVEF) and left ventricular fractional shortening (LVFS) values were associated with symptom improvement after metoprolol therapy for children and adolescents with POTS.@*METHODS@#This retrospective study evaluated 51 children and adolescents with POTS who received metoprolol therapy at the Peking University First Hospital between November 2010 and July 2019. All patients had completed a standing test or basic head-up tilt test and cardiac echocardiography before treatment. Treatment response was evaluated 3 months after starting metoprolol therapy. The pre-treatment baseline LVEF and LVFS values were evaluated for correlations with decreases in the symptom score after treatment (ΔSS). Multivariable analysis was performed using factors with a P value of  0.050). However, responders had significantly higher baseline LVEF (71.09% ± 4.44% vs. 67.17% ± 4.88%, t = -2.789, P = 0.008) and LVFS values (40.00 [38.00, 42.00]% vs. 36.79% ± 4.11%, Z = -2.542, P = 0.010) than the non-responders. The baseline LVEF and LVFS were positively correlated with ΔSS (r = 0.378, P = 0.006; r = 0.363, P = 0.009), respectively. Logistic regression analysis revealed that LVEF was independently associated with the response to metoprolol therapy in children and adolescents with POTS (odds ratio: 1.201, 95% confidence interval: 1.039-1.387, P = 0.013).@*CONCLUSIONS@#Pre-treatment baseline LVEF was associated with symptom improvement after metoprolol treatment for children and adolescents with POTS.

ABSTRACT

Neonicotinoid is a kind of neuroactive pesticide, and it has become the most widely used pesticide in the world. In recent years, neonicotinoid has been detected in the environment and food, suggesting that human can be exposed to this kind of pesticide through drinking water, ingestion and respiration, which poses potential health hazards to human. However, there is no comprehensive report on the pollution level of neonicotinoid pesticides in the environment and food and the impact on human health. In this paper, the pollution status, population exposure level and potential health risks of neonicotinoid pesticides in water, air and food were reviewed. We found that neonicotinoid residues are widespread in fruits and vegetables, of which imidacloprid has the highest detection rate. Except for a few samples with excessive neonicotinoid detection, the detection level in most samples did not exceed national food safety standards. A variety of neonicotinoid pesticides have been detected in the air, surface water, tap water and drinking water. External exposure studies in the population have shown that ingestion is the main route of exposure to neonicotinoid, and the external exposure level is much lower than its chronic reference dose. The internal exposure study mainly detected the concentration of neonicotinoid pesticides and their metabolites in urine. A variety of neonicotinoid pesticides and their metabolites are detected in urine, and the concentration range is ng/ml level. Internal exposure studies found that the detection rate of thiamethoxam and dinotefuran in urine is higher, and the detection rate of neonicotinoid in Asian countries is higher than that in European and American countries. Occupational exposure studies found that neonicotinoid exposure levels increased after pesticide spraying, and the exposure levels in rural areas where pesticides were commonly used were higher than those in neighboring urban areas. Animal experiments have found that neonicotinoid pesticides have reproductive toxicity, genetic toxicity, neurotoxicity, immunotoxicity, liver toxicity and nephrotoxicity to non-target organisms. Cell experiments suggest that neonicotinoid is an endocrine disruptor. The symptoms of acute exposure in humans are related to the exposure dose, route and physical condition of the exposed person, which ranges from mild symptoms (nausea, vomiting, headache and diarrhea) to death. Population epidemiological studies have shown that chronic exposure to neonicotinoid pesticides is associated with adverse health effects in humans such as neonatal tetralogy of Fallot, anencephaly, and adverse mental symptoms.

ABSTRACT

Objective:To evaluate the efficacy and safety of Tyrosine Kinase Inhibitors (TKIs) combined with stereotactic body radiation therapy(SBRT) in the treatment of renal cell carcinoma (RCC) patients with bone metastasis.Methods:The clinical data of 80 RCC patients with bone metastasis in Sun Yat-sen University Cancer Center from April 2010 to April 2020 were analyzed retrospectively. Among them, 64 patients were medium or high risk according to the International Metastatic Renal Cell Carcinoma Database Consortium(IMDC) score. Twenty-four patients received TKI therapy alone(Group A), and the other 56 cases received TKIs combined with SBRT to bone metastastic lesions (Group B).Results:The median follow-up period was 20.7 months (4.8-115.6 months), 70 patients received second or third-line targeted drug therapy, and 4 patients in group A and 15 patients in group B received TKI plus immunotherapy. Fifty-four patients had symptoms of bone pain before radiotherapy, 46 patients were satisfied with the analgesic effect after SBRT treatment. Twelve patients got complete response (CR) after bone lesions, and 32 patients achieved partial response (PR). Forty patients died of disease progression during follow-up. The median OS was: 20.7 months vs not reached(Group A vs. Group B), and the 2-y OS and 5-y OS were 50% vs. 62%, and 19% vs. 56%, respectively ( P=0.006). There were only 2 patients (3.6%) had grade 3 SBRT related adverse events. Conclusions:SBRT combined with TKIs improved the quality of life and prolonged the overall survival of RCC patients with bone metastasis.

ABSTRACT

Objective:To evaluate the preliminary clinical efficacy and safety of stereotactic body radiation therapy (SBRT) in combination with targeted therapy for metastatic renal cell carcinoma (mRCC).Methods:Clinical data of 58 patients with mRCC who were treated with SBRT in combination with targeted therapy in Sun Yat-sen University Cancer Center from June 2013 to December 2018 were retrospectively analyzed. Among them, 79.3% patients were classified as intermediate or high risk according to International Metastatic Renal Cell Carcinoma Database Consortium Criteria. The median biologically equivalent dose (BED) was 147 Gy (67 to 238 Gy).Results:Overall, 32, 13, 7, 5 and 1 patients received SBRT for 1, 2, 3, 4 and 6 metastatic sites (105 lesions) and 71.4% of them were bone lesions. Targeted therapy was continued during SBRT. With a median follow-up of 9.4 months (range 2.7 to 40.1 months), 18 patients died. The 1-year local control rate was 97.4%. The 1-year progression-free survival was 50.3%. The 1-and 2-year overall survival was 72% and 53%. Approximately 85% patients experienced pain relief after SBRT. Patients who achieved complete or partial response after SBRT obtained better overall survival than those with stable disease or disease progression (1-year overall survival: 83% vs. 48%, P=0.021). In the whole cohort, 6 cases developed Grade Ⅲ adverse events, 4 of which were Grade Ⅲ myelosuppression, 1 case of Grade Ⅲ neuropathy and 1 case of radiation-induced skin injury. Conclusion:Preliminary study reveals that combined use of targeted therapy and SBRT is an efficacious and safe treatment of advanced mRCC.

ABSTRACT

Objective:To investigate the effect of Chinese reading aloud training (c-RAT) on cognitive function and activities of daily living in patients with vascular cognitive impairment no dementia (VCIND).Methods:From January 2018 to January 2019, totally 80 patients with VCIND in the General Hospital of Xingtai Mining Group were enrolled.Subjects were randomized grouped into c-RAT group ( n=43) and control group ( n=37). The c-RAT group was asked to read aloud the Chinese paper for 5 days a week for 12 weeks.At the time of enrollment and 12 weeks after the intervention, the Montreal cognitive assessment (MoCA), trail making test (TMT), auditory verb learn test (AVLT), digit symbol substitution test (DSST) and modified Barthel index (MBI) were filled out. Results:Compared with control group, the difference of D-value in c-RAT group was statistically significant in MoCA total scores(4.00(2.00), 1.50(0.50), Z=3.012, P=0.003), scores of MoCA-Visual space execution (2.00(1.00), 0.00(2.00), Z=2.787, P=0.008), MoCA-attention (1.00(1.00), 0.00(0.50), Z=2.369, P=0.022), MoCA-language (1.00(1.00), 0.00(0.75), Z=3.049, P=0.000)and MoCA-delayed recall(2.00(2.00), 0.00(1.00), Z=2.043, P=0.014), TMT-A scores (-8.00(23.00), 10.50(30.25), Z=2.120, P=0.039), AVLT scores (1earning)(3.00(2.00), 0.50(0.75), Z=2.266, P=0.039) , AVLT scores (recall)(2.00(1.00), 0.00(1.00), Z=2.974, P=0.003)、AVLT scores (recognition) (2.00(0.00), 0.50(1.50), Z=3.054, P=0.000)and DSST scores ((4.96±0.71), (2.39±0.78), t=2.572, P=0.014), while there were no significant differences in the rest parts of MoCA, TMT-B and MBI( P>0.05). The increased scores in DSST were positively correlated ( r=0.205, P=0.006) with the number of reading aloud tasks finished. Conclusion:C-RAT can improve general cognition, especially in information processing speed, executive function, attention and auditory memory.

ABSTRACT

In recent years, the research of immune checkpoint inhibitors has made a great breakthrough in lung cancer treatment. Currently, a variety of immune checkpoint inhibitors have been applied into clinical practice, including antibodies targeting the programmed cell death-1, programmed cell death-ligand 1, and cytotoxic T-lymphocyte antigen 4, and so on. However, not all patients can benefit from the treatment. Abnormal antigen presentation, functional gene mutation, tumor microenvironment, and other factors can lead to primary or secondary resistance. In this paper, we reviewed the molecular mechanism of immune checkpoint inhibitor resistance and various combination strategies to overcome resistance, in order to expand the beneficial population and enable precision medicine.

ABSTRACT

Objective: To provide electrophysiological evidence for RIN-14B cells as an useful model of enterochromaffin cells (EC) and to study the role of Nav1. 3 channel in the control of its excitability. Methods: Resting membrane potential was recorded and the effects of TTX and ICA-121431 were examined by current-clamp in cultured RIN-14B cells. The effects of TTX and ICA-121431 on Na+ current of RIN-14B cells were examined by voltage-clamp. Results: RIN-14B cells had a resting potential around -60 mV and fired action potentials when stimulated with depolarizing current pulses. The action potential was completely blocked by TTX and inhibited by ICA-121431 in a dose-dependent manner. TTX blocked activation and inactivation of sodium current. In addition ICA-121431 dose-dependently inhibited activation of Na+ current. Conclusion: The action potential of RIN-14B cells is induced by TTX-sensitive sodium channel and the excitability is controlled by Nav1.3. These results suggest RIN-14B cells are similar to EC and it may be a good model of EC.

ABSTRACT

Objective@#To study the characteristics and correlation of sex hormone levels, blood lipids, and visceral fat area in postmenopausal women with T2DM.@*Methods@#A total of 258 cases of postmenopausal T2DM were recruited, including 46 cases of menopause for 1-5 years (group A), 49 cases of menopause for 6-10 years (group B), and 163 cases with menopause more than 10 years (C group). The related clinical information of patients was recorded.@*Results@#Compared among the three groups, there were statistical differences in total cholesterol(F=3.287, P=0.039) and testosterone(Chi-Square=8.324, P=0.016). No significant difference in FSH, LH, estradiol, low density lipoprotein, triglyceride, visceral fat area and subcutaneous fat area(P>0.05) among three groups was observed. After correction of confounding factors, FSH was independently positively related with for total cholesterol and low-density lipoprotein respectively (P=0.006, P=0.009). LH was independently positively related with total cholesterol(P=0.003) and low-density lipoprotein respectively(P=0.003). Estradiol was independently negatively related with total cholesterol(P=0.014) and low-density lipoprotein(P=0.020), respectively. Testosterone was correlated independently with visceral fat area(P=0.008); FSH, LH, estradiol, and testosterone were not correlated to triglyceride and subcutaneous fat area(P>0.05).@*Conclusion@#(1)In T2DM patients with the increase of postmenopausal time, the total cholesterol increases first, and then decreases; testosterone decreases first, and then increases. (2)In T2DM patients, the total cholesterol and low-density lipoprotein increase with the increase of FSH and LH, increase with the decrease of estradiol, and the area of visceral fat increases with the testosterone together.

ABSTRACT

Objective To explore the effect of Omaha system nursing model on nutritional status and disease condition of patients with low body mass and chronic obstructive pulmonary disease (COPD). Methods Sixty COPD patients with low body mass who were admitted to the First Affiliated Hospital of Huzhou University from January 2015 to November 2016 were enrolled, and they were randomly divided into an Omaha system nursing model group and a routine care intervention group, with 30 cases in each group. The Delphi expert consultation method was used to construct the Omaha nursing problem system and intervention system for COPD patients with low body mass. The patients in the routine care intervention group were given routine care intervention; the patients in the Omaha system nursing model group underwent nutritional intervention according to the Omaha system nursing model. The Mini Nutritional Assessment (MNA), COPD Assessment Test (CAT) and the modified Medical Research Council Dyspnea Scale (mMRC) were used to be the evaluation system of the Omaha system nursing model, the changes of MNA, CAT and mMRC evaluation scores on admission and in 1, 3, and 6 months after discharge in the two groups were recorded, and the correlations between MNA score and CAT, mMRC scores were analyzed. Results Omaha system analysis showed that the main health problems of the Omaha system nursing model group were distributed in the environmental (17.86%), social psychological (8.93%), physiological (19.64%), and health-related behavioral (53.57%) aspects, among which health-related behaviors were mostly common. There were no statistical significant differences in the scores of CAT, mMRC, and MNA between the two groups on admission (all P > 0.05). The CAT and mMRC scores of the Omaha system nursing model group in 1, 3, and 6 months after discharge were significantly lower than those on admission (CAT score: 16.98±2.39, 16.67±2.55, 15.36±2.17 vs. 25.76±3.67; mMRC score: 2.35±0.57, 1.97±0.52, 1.49±0.51 vs. 3.07±0.55, all P < 0.05), MNA scores were significantly higher than those on admission (11.89±3.57, 13.97±3.52, 15.49±3.51 vs. 10.33±3.02, all P < 0.05), and along with the prolongation of time the decrease and increase in scores were more significant. The scores of the Omaha system nursing model group were improved more significantly in 1, 3 and 6 months after discharge than those of the routine care intervention group (CAT score: 16.98±2.39, 16.67±2.55, 15.36±2.17 vs. 23.01±2.67, 21.15±2.79, 19.06±2.61; mMRC score: 2.35±0.57, 1.97±0.52, 1.49±0.51 vs. 3.06±0.65, 3.06±0.61, 2.65±0.67;MNA score: 11.89±3.57, 13.97±3.52, 15.49±3.51 vs. 9.96±3.15, 10.06±3.09, 8.55±3.17, all P < 0.05]. Pearson correlation analyses showed that MNA score was significantly negatively correlated with CAT score (r = -0.493, P = 0.001) and with mMRC score (r = -0.594, P = 0.001) respectively. Conclusion Using the Omaha system nursing model for nutrition intervention in COPD patients with low body mass can significantly improve their nutritional status and disease condition as well as quality of life.
