ABSTRACT

CT screening has markedly reduced the lung cancer mortality in high-risk population and increased the detection of early-stage pulmonary neoplasms, including multiple pulmonary nodules, especially those with a ground-glass appearance on CT. Multiple primary lung cancer (MPLC) constitutes a specific subtype of lung cancer with indolent biological behaviors, which is predominantly early-stage adenocarcinoma. Although MPLC progresses slowly with rare lymphatic metastasis, existence of synchronous lesions and distributed location of these nodules still pose difficulty for the management of such patients. One single operation is usually insufficient to eradicate all neoplastic lesions, whereas repeated surgical procedures bring about another dilemma: whether clinical benefits of surgical treatment outweigh loss of pulmonary function following multiple operations. Therefore, despite the anxiety for treatment among MPLC patients, whether and how to treat the patient should be assessed meticulously. Currently there is a heated discussion upon the timing of clinical intervention, operation mode and the application of local therapy in MPLC. Based on clinical experience of our multiple disciplinary team, we have summarized and commented on the evaluation, surgical treatment, non-surgical local treatment, targeted therapy and immunotherapy of MPLC in this article to provide further insight into this field.

ABSTRACT

ObjectiveTo observe the clinical efficacy of Gandouling decoction combined with cognitive behavioral therapy (CBT) in the treatment of impulse control disorders in patients with Wilson's disease (WD, syndrome of combined phlegm and stasis). MethodA prospective study was conducted on 90 WD patients with the syndrome of combined phlegm and stasis and impulse control disorders (ICD) treated in the Department of Encephalopathy of the First Affiliated Hospital of Anhui University of Chinese Medicine from August 2018 to February 2023. They were randomized into a control group, a CBT group, and a treatment group, with 30 patients in each group. The control group received routine Western medicine treatment (basic copper removal). The CBT group received cognitive behavioral therapy in addition to the therapy in the control group, and the treatment group received Gandouling decoction in addition to the therapy in the CBT group. Each course of treatment was 8 days, and the patients were treated for 4 courses. Before and after treatment, the 24-hour urine copper (24 h U-Cu), non-ceruloplasmin-bound copper (NCC), traditional Chinese medicine (TCM) syndrome score, unified WD rating scale part Ⅲ (UWDRS Ⅲ) score, Barratt Impulse Scale Version 11 (BIS-11) score, Buss-Perry aggression questionnaire (BPAQ) score, modified overt aggression scale (MOAS) score, and treatment emergent symptom scale (TESS) score of three groups of patients were determined and statistically analyzed. ResultBefore treatment, there was no statistically significant difference in the level of 24 h U-Cu or NCC among the three groups. After treatment, all the three groups showed an increase in 24 h U-Cu (P<0.01) and a decrease in the NCC level (P<0.05, P<0.01). There was no significant difference in the 24 h U-Cu level among the three groups after treatment. After treatment, the NCC level showed no significant difference between the control group and the CBT group, while the NCC level in the treatment group was lower than that in the control group and CBT group (P<0.05). Before treatment, there was no statistically significant difference in the TCM syndrome score among the three groups. After treatment, the TCM syndrome scores of all the three groups decreased (P<0.01). Moreover, the treatment group had lower TCM syndrome score than the control group and CBT group (P<0.05). Before treatment, the UWDRS Ⅲ, BIS-11, BPAQ, and MOAS scores had no statistically significant differences among the three groups. After treatment, the UWDRS Ⅲ, BIS-11, BPAQ, and MOAS in all the three groups declined (P<0.05). Moreover, the CBT group and treatment group had lower UWDRS Ⅲ, BIS-11, BPAQ, and MOAS scores than the control group (P<0.05), and the treatment group had lower BIS-11 and BPAQ scores than the CBT group (P<0.05). ConclusionThe combination of Gandouling decoction and CBT can ameliorate impulse control disorders in the WD patients with combined phlegm and stasis.

ABSTRACT

Objective:To investigate the efficacy of different treatment modes for locoregional recurrence after nephrectomy in patients with renal cell carcinoma.Methods:A total of 106 patients with locoregional recurrence after nephrectomy without distant metastasis (77 males and 29 females) admitted to Sun Yat-sen University Cancer Center from October 2001 to July 2020 were retrospectively analyzed. The median age was 51 (40, 60) years old. Radical nephrectomy was performed in 90 patients with primary tumor and partial nephrectomy was performed in 16 patients. Pathological diagnosis showed that 54 cases were clear cell carcinoma and 52 cases were non-clear cell carcinoma. 53 cases were in stage T 1-2 and 53 cases in stage T 3-4. The median diameter of recurrent lesions was 3.2 (2.0, 6.3) cm, and the median number was 2 (1, 4). The recurrence sites were divided into renal fossa recurrence (33 cases), renal fossa±retroperitoneal lymph node recurrence (38 cases), and intra-abdominal spread (35 cases). The median duration from primary surgery to local recurrence was 14.8 (7.3, 35.8) months. Two treatment groups were identified as systemic therapy alone (Group A) and local therapy with or without systemic therapy (Group B). The Kaplan-Meier method was used to compare the progression free survival (PFS) and overall survival (OS) between Group A and Group B. The Cox model was used to perform univariate and multivariate analysis. Results:Of all the 106 patients, 33 patients were in Group A and 73 patients were in Group B. In Group A, 29 patients (87.9%) received targeted therapy, and 4 patients (12.1%) received targeted therapy combined with immunotherapy. In Group B, 34 patients (46.6%) received surgery or ablation and 39 patients (53.4%) received SBRT, of which 62 patients (84.9%) received concurrent systemic therapy. Among them, 58 patients (93.5%) received targeted therapy, and 4 patients (6.5%) received targeted therapy combined with immunotherapy. The median follow-up period was 29.0 (15.4, 45.9) months, 64 patients progressed on tumor including 28 patients died. The median PFS and OS were 15.6 (7.1, 35.2) months and 66.9 (37.8, not reached) months. The median PFS of Group A and Group B were 7.6(5.0, 17.2)months and 22.2(9.6, 63.9)months respectively ( P=0.001), median OS of Group A and Group B were 45.7 (23.4, 62.8)months and 71.0(50.6, not reached)months respectively, and the 2-year OS were 70.6% and 85.5% in Group A and Group B respectively ( P=0.023). The univariate analysis showed local therapy with or without systemic therapy was significantly reduced 56% risk of tumor progression ( HR=0.44, P=0.003) and reduced 60% risk of death ( HR=0.40, P=0.028). The multivariate analysis showed that the OS was associated with ECOG score( HR=10.20, 95% CI 4.13-25.30, P<0.001)and local therapy( HR=0.23, 95% CI 0.09-0.58, P=0.002). Conclusion:Compared with systemic therapy alone, local therapy with or without systemic therapy can effectively improve the PFS and OS of patients with locoregional recurrence after nephrectomy.

ABSTRACT

Objective:The hemodynamic parameters of elderly patients with septic shock were measured simultaneously with pulse index continuous cardiac output(PiCCO)and thoracic electrical bioimpedance(TEB)to evaluate the accuracy of TEB and to provide empirical evidence for its clinical use.Methods:A total of 24 elderly patients with septic shock admitted to the intensive care unit of our hospital between July 2021 and December 2021 were retrospectively recruited.TEB and PiCCO hemodynamic monitoring were performed continuously in all patients, and hemodynamic data were collected for statistical analysis.Results:Cardiac output, cardiac index, stroke volume, stroke index and systemic vascular resistance measured by the two methods had no significant difference( P>0.05). The 95% confidence intervals in the Bland-Altman plots for cardiac output, CI, stroke volume, stroke index, and systemic vascular resistance were(-1.18, 1.25), (-0.65, 0.71), (-24.23, 37.00), (-12.93, 19.26)and(397.11, 425.83). In the Bland-Altman plots for cardiac output, cardiac index, stroke volume and systemic vascular resistance, 4.17% of the points(1/24)fell outside of the 95% confidence interval, and in the Bland-Altman plots for stroke index, 8.33% of the points(2/24)fell outside of the 95% confidence interval. Conclusions:TEB and PiCCO have good consistency in evaluating the hemodynamics of elderly patients with septic shock.Therefore, TEB can be recommended for community hospitals and used in elderly patients.

ABSTRACT

Objective@#To understand the relationship among pubertal timing, overweight and obesity, and eating disorders among Bengbu adolescents, and to provide a reference for obesity prevention.@*Methods@#Two nine year schools were conveniently selected in Bengbu, with 683 students from grade 5 to grade 8. Puberty Development Scale (PDS) and Eating Disorders Inventory of Children (EDI-C) subscale were used, height and weight were measured. The associations between obesity, pubertal timing and eating disorders were analyzed.@*Results@#The prevalence of overweight and obesity was higher in boys than that in girls, and the rate of early pubertal timing, drive for thinness score, body dissatisfaction score and total eating disorder score were higher in girls than that in boys( χ 2/t =28.69, 57.99, 3.47, 2.59, 3.30, P <0.05). The differences in rate of overweight and obesity, bulimia score and total eating disorder score were statistically significant by grade( χ 2/F =28.39, 5.11, 3.95, P <0.01). There was a positive correlation among overweight obesity and early pubertal timing and eating disorder, and a positive correlation between early pubertal timing and eating disorder( r =0.18, 0.17, 0.14, P < 0.01 ). The mediating effect of early pubertal timing between overweiht, obesity and eating disorders partially contributed 14.25% to the total effect.@*Conclusion@#Overweight and obesity is associated with eating disorders, and early pubertal timing partially mediate the association between overweight obesity and eating disorders. Healthy lifestyle should be advocated in family and school to effectively prevent adolescents obesity, pubertal timing, and eating disorders.

ABSTRACT

AIM: To explore the efficacy of preoperative intravitreal injection of conbercept combined with 25G+ pars plana vitrectomy(PPV)in the treatment of proliferative diabetic retinopathy(PDR).METHODS: The clinical data of 154 patients(176 eyes)with PDR admitted to our hospital from January 2019 to June 2021 were collected for retrospective analysis. According to the treatment methods, 80 patients(92 eyes)in combined treatment group were treated with preoperative intravitreal injection of conbercept combined with 25G+PPV, and 74 patients(84 eyes)in control group were given 25G+PPV only. The postoperative clinical efficacy and levels of adipokines [adiponectin(APN), retinol binding protein 4(RBP4)] before and after surgery were compared between both groups of patients.RESULTS: The combined treatment group showed better clinical efficacy than the control group at 1mo after surgery(P&#x003C;0.05). Both groups had lower RBP4 levels at 3mo after surgery(P&#x003C;0.05), with the combined treatment group showing a lower level than the control group(P&#x003C;0.05). Serum APN levels significantly increased in both groups after surgery(P&#x003C;0.05), with the combined treatment group having a higher level than the control group(P&#x003C;0.05). The combined treatment group had lower incidence rates of retinal proliferation and postoperative complications after than the control group 3mo of follow-up(P&#x003C;0.05).CONCLUSION: Preoperative intravitreal injection of conbercept combined with 25G+PPV is beneficial in improving the therapeutic effect of PDR and reducing the incidence rates of complications, which may be related to the regulations of the expressions of adipokines.

ABSTRACT

In 2021, a total of 151 pregnant women were selected from the suburb of Shanghai. A questionnaire survey was conducted to obtain data about maternal age, gestational week, total annual household income, education level and passive smoking among pregnant women and one spot urine was collected. The concentrations of eight neonicotinoid pesticides and four metabolites in urine were measured by ultra-high performance liquid chromatography-tandem quadrupole time-of-flight mass spectrometry. The differences in detection frequencies and concentrations of neonicotinoid pesticides and their metabolites among pregnant women with different characteristics were compared, and the influencing factors of the detection of neonicotinoid pesticides in urine were analyzed. The results showed that at least one neonicotinoid pesticide was detected in 93.4% (141 samples) of urine samples. The detection frequencies of N-desmethyl-acetamiprid, clothianidin, thiamethoxam, and N-desmethyl-clothianidin were high, about 78.1% (118 samples), 75.5% (114 samples), 68.9% (104 samples), and 44.4% (67 samples), respectively. The median concentration of the sum of all neonicotinoid pesticides was 2.66 μg/g. N-desmethyl-acetamiprid had the highest detection concentration with a median concentration of 1.04 μg/g. A lower urinary detection frequency of imidacloprid and its metabolites was seen in pregnant women aged 30-44 years [OR (95%CI): 0.23 (0.07-0.77)]. A higher detection frequency of clothianidin and its metabolites was seen in pregnant women with per capita annual household income≥100 000 yuan [OR (95%CI): 6.15 (1.56-24.28)]. There was widespread exposure to neonicotinoid pesticides and their metabolites in pregnant women from the suburb of Shanghai, which might pose potential health risks to pregnant women, and maternal age and household income were potential influencing factors of the exposure to neonicotinoid pesticides.

ABSTRACT

OBJECTIVES@#To study the efficacy and safety of rituximab combined with chemotherapy in the treatment of children and adolescents with mature B-cell non-Hodgkin's lymphoma (B-NHL) through a Meta analysis.@*METHODS@#The databases including PubMed, Embase, the Cochrane Library, ClinicalTrials.gov, Web of Science, China National Knowledge Infrastructure, Wanfang Data, and Weipu were searched to obtain 10 articles on rituximab in the treatment of mature B-NHL in children and adolescents published up to June 2022, with 886 children in total. With 3-year event-free survival (EFS) rate, 3-year overall survival (OS) rate, complete remission rate, mortality rate, and incidence rate of adverse reactions as outcome measures, RevMan 5.4 software was used for Meta analysis, subgroup analysis, sensitivity analysis, and publication bias analysis.@*RESULTS@#The rituximab+chemotherapy group showed significant increases in the 3-year EFS rate (HR=0.38, 95%CI: 0.25-0.59, P<0.001), 3-year OS rate (HR=0.29, 95%CI: 0.14-0.61, P=0.001), and complete remission rate (OR=3.72, 95%CI: 1.89-7.33, P<0.001) as well as a significant reduction in the mortality rate (OR=0.31, 95%CI: 0.17-0.57, P<0.001), as compared with the chemotherapy group without rituximab. There was no significant difference in the incidence rate of adverse reactions between the two groups (OR=1.28, 95%CI: 0.85-1.92, P=0.24).@*CONCLUSIONS@#The addition of rituximab to the treatment regimen for children and adolescents with mature B-cell non-Hodgkin's lymphoma can bring significant survival benefits without increasing the incidence of adverse reactions.

ABSTRACT

Objectives: To analyze the long-term survival of patients with localized renal cell carcinoma after partical nephrectomy. Methods: The clinicopathological records and survival follow-up data of 2 046 patients with localized renal cell carcinoma, who were treated with partial nephrectomy from August 2001 to February 2021 in the Department of Urology, Sun Yat-sen University Cancer Center, were retrospectively analyzed. There were 1 402 males and 644 females, aged (M(IQR)) 51 (19) years (range: 6 to 86 years). The primary end point of this study was cancer-specific survival. Survival curves were estimated using the Kaplan-Meier method, and the difference test was performed by Log-rank test. Univariate and multivariate Cox analysis were fitted to determine factors associated with cancer-specific survival. Results: The follow-up time was 49.2 (48.0) months (range: 1 to 229 months), with 1 974 patients surviving and 72 dying. The median cancer-specific survival time has not yet been reached. The 5- and 10-year cancer specific survival rates were 97.0% and 91.2%, respectively. The 10-year cancer-specific survival rates for stage pT1a (n=1 447), pT1b (n=523) and pT2 (n=58) were 95.3%, 81.8%, and 81.7%, respectively. The 10-year cancer-specific survival rates of patients with nuclear grade 1 (n=226), 2 (n=1 244) and 3 to 4 (n=278) were 96.6%, 89.4%, and 85.5%, respectively. There were no significant differences in 5-year cancer-specific survival rates among patients underwent open, laparoscopic, or robotic surgery (96.7% vs. 97.1% vs. 97.5%, P=0.600). Multivariate analysis showed that age≥50 years (HR=3.93, 95%CI: 1.82 to 8.47, P<0.01), T stage (T1b vs. T1a: HR=3.31, 95%CI: 1.83 to 5.99, P<0.01; T2+T3 vs. T1a: HR=2.88, 95%CI: 1.00 to 8.28, P=0.049) and nuclear grade (G3 to 4 vs. G1: HR=2.81, 95%CI: 1.01 to 7.82, P=0.048) were independent prognostic factors of localized renal cell carcinoma after partial nephrectomy. Conclusions: The long-term cancer-specific survival rates of patients with localized renal cancer after partial nephrectomy are satisfactory. The type of operation (open, laparoscopic, or robotic) has no significant effect on survival. However, patients with older age, higher nuclear grade, and higher T stage have a lower cancer-specific survival rate. Grasping surgical indications, attaching importance to preoperative evaluation, perioperative management, and postoperative follow-up, could benefit achieving satisfactory long-term survival.

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 evaluate the clinical efficacy of Yangxue-Qingnao granule combined with ligustrazine injection in the treatment of wind-phlegm entering collaterals syndrome of cerebral infarction. Methods:A total of 96 patients with cerebral infarction and wind-phlegm entering collaterals syndrome to Suixi County Hospital of Traditional Chinese Medicine from January 2019 to December 2019 were selected and randomly divided into two groups by random number table method, with 48 in each group. The control group was given intravenous ligustrazine injection, and the observation group was given Yangxue-Qingnao granule on the basis of the treatment of the control group. Both groups were treated continuously for 2 weeks. TCM syndrome scores were performed before and after treatment, the National Institutes of Health Stroke Scale (NIHSS) was used to assess the degree of neurological impairment, and the Activity of Daily Living Scale (ADL) was evaluated. To evaluate the patient's quality of life, to detect the high-shear viscosity, low-shear viscosity and plasma viscosity of whole blood with an automatic hemorheology instrument. Results:The total effective rate of the observation group was 95.8% (46/48) and that of the control group was 70.8% (34/48). The difference between the two groups was statistically significant ( χ2=9.08, P<0.01). After treatment, the TCM syndrome score of the observation group was significantly lower than that of the control group ( t=3.51, P<0.01), the NIHSS score was significantly lower than that of the control group ( t=34.41, P<0.001), and the ADL score was significantly higher than that of the control group ( t=57.88, P<0.01). After treatment, the observation group's whole blood high shear viscosity [(5.04 ± 0.93)mPa?s vs. (5.64 ± 1.13)mPa?s, t=2.84], whole blood low shear viscosity [(11.32 ± 1.74)mPa?s vs. (13.39 ± 2.23)mPa?s, t=5.07] and plasma viscosity [(1.51 ± 0.33)mPa?s vs. (1.73 ± 0.47)mPa?s, t=2.65] of the observation group were significantly lower than those in the control group ( P<0.05 or P<0.01). Conclusion:Yangxue-Qingnao granule combined with ligustrazine injection can improve the neurological status and quality of life of patients with cerebral infarction syndrome of wind-phlegm entering the collaterals, and improve the clinical efficacy.

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

Background@#Topical corticosteroids are the mainstay of treatment for patients with atopic dermatitis. However, adverse effects associated with long-term steroid use often limit its use. This interventional study compared the efficacy of a proprietary moisturiser containing licochalcone A, omega-6 fatty acids, and ceramide 3 against 1% hydrocortisone cream in treating patients with mild-to-moderate atopic dermatitis.@*Methods@#Patients with mild-to-moderate atopic dermatitis affecting either the cubital fossa or popliteal fossa symmetrically were given twice-daily applications of the moisturiser and hydrocortisone on opposite sides of the body and monitored for a total of three weeks in a non-randomised half body, doubleblind study. Hydrocortisone was switched to aqueous cream after two weeks, whereas the application of the moisturiser continued until study completion. The assessment of SCORing Atopic Dermatitis (SCORAD) index and Dermatology Life Quality index was performed at baseline and every subsequent follow-up visit to measure patients’ response to treatment. @*Results@#The licochalcone A (LA) moisturiser and 1% hydrocortisone (HC) cream both demonstrated significant reduction in sign and symptom scores after only 1 week of treatment (percentage of reduction in sign and symptom scores: 52.8% [LA] vs 58.5% [HC]). Further reduction in mean sign and symptom scores for both treatments was observed at week 2 (61.3% [LA] vs 56.8% [HC]) and also at week 3 when HC was switched to aqueous cream (70.5% [LA] vs 63.5% [HC→aqueous cream]) (p<0.001 vs baseline within the same treatment arm at weeks 1, 2 and 3). When comparing the mean difference in SCORAD index for both individual as well as total skin signs and symptoms between LA and HC (i.e. inter-arm comparison), there was no significant difference between the two treatments for all the assessed parameters. Patients reported improvements in itching, sleeplessness, and overall quality of life over the course of treatment.@*Conclusion@#The licochalcone A moisturiser can be considered as an effective steroid-sparing alternative to topical corticosteroids in managing mild-to-moderate atopic dermatitis.

ABSTRACT

Objective:To explore the application effect of dysphagia rehabilitation pathway nursing in patients with dysphagia after stroke.Methods:Eighty patients with dysphagia after stroke who were admitted to the hospital from October 2019 to April 2020 were enrolled as the research objects. They were divided into observation group and control group by random number table method, 40 cases in each group. The control group was given routine nursing intervention, while observation group was given dysphagia rehabilitation pathway nursing on basis of control group. The swallowing function, serum ALBumin (ALB), subcutaneous fat, weight, incidence of aspiration pneumonia and nutrition deficiency were compared between the two groups at admission, after 2 weeks and 4 weeks of intervention.Results:After 2 weeks of intervention, the number of cases with normal swallowing function in observation group was significantly more than that in control group (15, 30 vs 7, 21) ( χ2 value was 4.013, 4.381, P<0.05). After 4 weeks of intervention, number of cases with abnormal swallowing function in observation group was less than that in control group (2 vs 9) ( χ2 value was 5.165, P<0.05). After 4 weeks of intervention, level of plasma ALB and TSF, and weight in the observation group were significantly higher than those in the control group [(39.46±2.84)g/L, (19.28±2.20)mm, (19.28±2.20) kg vs (31.71±2.59)g/L, (17.06±2.35)mm, (62.48±4.29)kg]( t value was 12.752, 4.362, 2.317, P<0.05), while incidence rates of aspiration pneumonia and nutrition deficiency were significantly lower than those in control group [12.50% (5/40), 2.50% (1/40) vs 32.50% (13/40), 32.50% (13/40)] ( χ2 value was 4.588, 12.468, P<0.05). Conclusion:Application of dysphagia rehabilitation pathway nursing in patients with dysphagia after stroke can significantly promote the recovery of swallowing function, improve their nutrition status, and reduce incidence of aspiration pneumonia and nutrition deficiency.

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.
