ABSTRACT

ObjectiveTo conduct comprehensive assessment of internal and external cadmium exposure and health risks for Shanghai residents. MethodsCadmium levels in food samples were calculated by employing two dietary exposure assessment methods, total diet study (TDS) and food frequency questionnaire (FFQ), to estimate the daily dietary cadmium exposure of Shanghai residents. The provisional tolerable monthly intake (PTMI) of cadmium set by joint food and agriculture organization/WHO expert committee on food additives (JECFA) was applied to evaluate the health risk. Differences in dietary and urinary cadmium were compared by rank-sum test among different regions, age, gender, smoking status, and BMI groups, and the association between internal and external cadmium exposure was investigated by correlation analysis. ResultsThe mean value of urinary cadmium for 1 300 respondents was 0.542 μg·L-1. Urinary cadmium was higher in the population in central urban and urban-rural fringe areas than in the suburban area, higher in the older age group than in the younger age group, and higher in the smoking group than in the non-smoking group (all P<0.01). The two assessment methods showed that the mean values of daily dietary cadmium exposure for Shanghai residents were 0.306 and 0.090 μg·kg-1, with 3.69% and 0.85% of Shanghai residents exceeding the PTMI, respectively. Correlation analyses showed that dietary exposure to cadmium based on the FFQ method was positively correlated with the urinary cadmium level when smoking status, age, gender, and BMI were adjusted. ConclusionDietary exposure to cadmium of Shanghai residents is mainly derived from vegetables, aquatic products, cereals and potatoes, and is overall at a low-risk level. Dietary exposure assessment based on FFQ and risk monitoring data can effectively estimate long-term cadmium exposure.

ABSTRACT

This paper reports the clinical pharmacist participated in the diagnosis and treatment of a patient with acanthoma caused by nivolumab. This patient developed acanthoma 2 weeks after medication, involving scalp, neck, trunk, back of hand, sole of foot and other parts, with moderate pruritus. The clinical pharmacist determined it as “yes” according to the causality evaluation method of adverse reactions. After reviewing the literature, clinical pharmacists found that acanthoma caused by immune checkpoint inhibitors was more commonly seen in male elderly patients with malignant melanoma, and mainly involved the trunk, extremities and hands. Under the general principle of considering the effectiveness, safety, economy and accessibility of therapeutic drugs, the clinical pharmacist finally decided to give the patient a comprehensive treatment scheme of Halometasone cream for external use + oral administration of Retinoic acid capsules + oral administration of Ebastine tablets after discussion with the doctor, with maximum respect for the patient’s wishes,and continued to use navulizumab for immunotherapy. At the same time, pharmaceutical care and psychological counseling were conducted by clinical pharmacist. Finally, the patient successfully completed the treatment, and the acanthoma gradually subsided after the end of navulizumab treatment. The diagnosis and treatment process of this patient indicated that the participation of clinical pharmacists is helpful to improve the continuity and safety of immunotherapy.

ABSTRACT

Objective:To survey the health literacy and related factors of family caregivers of patients with chronic diseases in Beijing.Methods:A survey was conducted from September to November 2018, among 1 350 family caregivers of patients with chronic diseases selected by stratified random sampling from 6 districts of Beijing. A self-filling questionnaire was used for the survey, which consisted of the basic information and health literacy of family caregivers. Health literacy included three parts: daily living habits, basic knowledge (knowledge of prevention and management of behavioral risk factors, knowledge related to chronic diseases and knowledge related to first aid) and chronic disease-related skills.Results:A total of 1 268 valid questionnaires were collected with a recovery rate of questionnaires was 93.9%. The median age of 1 268 family caregivers was 62 years (23-86) and 75.7% (960/1 268) were females. In terms of daily habits, smokers and drinkers accounted for 11.3% (143/1 268) and 21.5% (272/1 268) respectively; 82.7% (1 049/1 268) caregivers exercised regularly accounted, of whom 72.5% (761/1 049) exercised at least 4 times a week; 28.9% (366/1 268) caregivers had habit of light diet. In terms of basic knowledge of health literacy, 12.9% (163/1 268) of family caregivers mastered the basic knowledge (≥80% total score); family caregivers who were able to measure blood pressure, blood sugar, pulse, coping with hypoglycemia, cardiopulmonary resuscitation and dialing the emergency number correctly accounted for 27.4% (347/1 268), 18.1% (230/1 268), 15.1% (191/1 268), 15.7% (199/1 268), 6.0% (76/1 268) and 33.8% (429/1 268), respectively. For the six chronic disease-related skills, 23.7% (301/1 268) were able to call emergency number correctly and only 2.6% (33/1 268) were able to perform CPR. There were significant differences in the knowledge of behavioral risk factors ( χ 2=3.88, P=0.017), chronic disease related knowledge ( χ2=7.40, P=0.025), first-aid related knowledge ( χ2=12.04, P=0.002) and overall basic knowledge ( χ2=13.56, P=0.001) among family caregivers with different educational levels. There were significant differences in the knowledge of chronic diseases among family caregivers in different occupations ( χ2=8.78, P=0.012). Conclusion:The health literacy level of family caregivers of patients with chronic diseases in Beijing needs to be further improved, and there are differences in the health literacy of family caregivers with different educational qualifications and occupations.

ABSTRACT

[Abstract] Objective To explore the inhibitory effect of sodium ferulate (SF) on the inflammatory response in migraine rats by regulating the c-Jun N-terminal kinase (JNK) / p38 mitogen-activated protein kinase (p38 MAPK) signaling pathway. Methods The migraine rat model was prepared by intraperitoneal injection of nitroglycerin. After successful modeling, the rats were randomly grouped into model group, SF low dose (SF-L) group (50 mg/ kg), SF high dose (SF-H) group (100 mg/ kg), SF+JNK inhibitor (SF + SP600125) group (SF 100 mg/ kg +SP600125 10 mg/ kg), and SF+JNK activator [SF + anisomycin(AN)] group (SF 100 mg/ kg +AN 5 mg/ kg), 12 in each group, another 12 SD rats without treatment were taken as blank group. The behavioral changes of the rats in each group were observed 24 hours after the administration, the levels of 5-hydroxytryptamine (5-HT), nitric oxide (NO), tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in serum were detected by ELISA, the neuronal apoptosis in brain tissue was observed by TUNEL staining, immunohistochemistry was used to evaluate the expressions of TNF-α, IL-6 and calcitonin gene-related peptide (CGRP) in brain tissue, Western blotting was used to detect the expressions of JNK/ p38 MAPK pathway-related proteins in brain tissue. Results Compared with the blank group, the number of times of scratching the head and climbing the cage of the rats in the model group increased significantly, and the apoptosis rate of neurons increased significantly; the content of 5-HT in serum decreased significantly, and the levels of NO, TNF-α and IL-6 increased significantly; the expressions of TNF-α, IL-6 and CGRP, and the ratios of phosphorylated JNK (p-JNK) / JNK and phosphorylated p38 MAPK(p-p38 MAPK) / p38 MAPK in brain tissue obviously increased (all P<0. 05). Compared with the model group, the number of times of scratching the head and the times of climbing the cage of the rats in the SF-L group and the SF-H group reduced significantly, and the neuron apoptosis rate reduced significantly; the content of 5-HT in serum increased significantly, and the levels of NO, TNF-α and IL-6 decreased significantly; the expressions of TNF-α, IL-6 and CGRP, and the ratios of p-JNK/ JNK and p-p38 MAPK/ p38 MAPK in brain tissue obviously decreased (all P<0. 05). Compared with SF-H group, the protective effect of SF on migraine rats in SF+SP600125 group enhanced significantly; the protective effect of SF on migraine rats in the SF+AN group reversed significantly. Conclusion SF may inhibit the expression of JNK/ p38 MAPK signaling pathway, effectively inhibit neurogenic inflammatory response in migraine rats, reduce neuronal apoptosis, and achieve a protective effect on migraine rats.

ABSTRACT

Based on the metabolomics, this paper systematically analyzed the metabolic substance basis of Zuogui Pills and Yougui Pills in syndrome differentiation and treatment of diminished ovarian reserve(DOR), so as to provide a scientific basis for the traditional Chinese medicine(TCM) syndrome differentiation and treatment of DOR. Patients with DOR of kidney-Yin deficiency syndrome were collected from outpatient department of hospitals and treated with Zuogui Pills for 12 weeks. And kidney-Yang deficiency syndrome were treated with Yougui Pills for 12 weeks. Based on the non-targeted metabolomic research techniques, the potential biomarkers of Zuogui Pills and Yougui Pills in the treatment of DOR with kidney-Yin deficiency and kidney-Yang deficiency, respectively, were screened out, and metabolic pathways of biomarkers were analyzed. The pregnancy rate, basic serum hormone levels [basal follicle-stimulating hormone(bFSH), basal-luteinizing hormone(bLH), basal-estradiol(bE_2), and anti-Müllerian hormone(AMH)], TCM syndrome type score, and Kupperman score were recorded and statistically analyzed after treatment. The results showed that 23 patients with DOR of kidney-Yin deficiency syndrome and 25 patients of kidney-Yang deficiency syndrome were collected. Twenty-six differential metabolites, including L-carnitine, acetyl-CoA, coenzyme A, and coenzyme Q_(10)(CoQ10), were mapped to 12 metabolic pathways in patients with kidney-Yin deficiency treated with Zuogui Pills. Twenty-two differential metabolites, such as adipoyl-CoA, L-lysine, lysine arginine, and α-tocopherol, were mapped to 11 metabolic pathways in patients with kidney-Yang deficiency. After treatment, bFSH and bLH of patients with DOR were significantly lower than those before treatment(P<0.05). Although the comparison of bE_2 and AMH had no significant differences, there was a improvement trend. The TCM syndrome type score and Kupperman score of patients with DOR after TCM treatment were significantly lower than those before treatment(P<0.05).

ABSTRACT

Objective: To investigate the clinicopathological characteristics and prognosis of mature T/NK cell lymphomas with aberrant CD20 or CD79α expression. Methods: A retrospective analysis of 641 cases of mature T/NK cell lymphoma diagnosed from January 2014 to December 2020 was performed, and 14 cases of CD20-positive and one case of CD79α-positive mature T/NK-cell lymphoma were identified. Histological examination, immunohistochemical characterization, in situ hybridization for Epstein-Barr virus encoded early RNA (EBER), and PCR testing for immunoglobulin and T cell receptor (TCR) gene rearrangements were performed. Clinicopathological characteristics of these lymphomas were analyzed. Results: There were 13 males and 2 females, with a median age of 56 years. There were 8 cases of peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS), 3 cases of extranodal NK/T-cell lymphoma, nasal type (ENKTCL), 2 cases of monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL) and 2 cases of angioimmunoblastic T-cell lymphoma (AITL). Twelve cases were stage Ⅲ or Ⅳ lymphomas. The prognosis was overall poor. The histology, immunophenotype and TCR gene rearrangement were not significantly different from the corresponding types of lymphoma. Ki-67 proliferation index was over 70% in all cases. The expression of CD20 or CD79α was weak and heterogeneous. All 15 case of Ig gene rearrangement were polyclonal. Conclusions: Mature T/NK cell lymphoma with abnormal expression of CD20 or CD79α is rare, commonly found in advanced stage, and associated with poor prognosis. The expression of CD20 or CD79α in these cases is weaker than the corresponding mature T/NK cell lymphomas, while its proliferation index is higher. Histomorphology, extensive immunoprofiling and molecular detection are required for accurate diagnosis.

ABSTRACT

Objective:To survey the training needs for chronic diseases among family health care workers in Beijing.Methods:A questionnaire survey on training needs for chronic disease was conducted from September to November 2018 among 820 family health care workers from 15 community health service centers in Beijing selected by stratified random sampling. The questionnaire consisted of demographic information and training needs related to chronic diseases. The training needs included: the knowledge and skills related to chronic diseases: the types of chronic diseases expected to learn, the basic knowledge of chronic diseases (7 items), preventive health care knowledge (7 items), nursing and rehabilitation skills (9 items); the duration, frequency, method, time and location of training arrangement.Results:The survey showed that chronic disease that family health care workers most wanted to learn was hypertension (90.3%, 717/794); among the basic knowledge of chronic diseases, the highest need was disease risk factor (65.5%, 520/794); among the knowledge of preventive health care, the highest need was home safety protection (87.3%, 693/794); among nursing and rehabilitation skills, the highest need was blood glucose measurement (83.1%, 660/794). The female respondents had higher training need for basic knowledge of chronic diseases than males ( Z=2.51, P=0.012). There were significant differences in the needs for preventive health care knowledge among respondents of different gender ( Z=2.72, P=0.007), occupation ( H=15.02, P=0.001) and educational level ( H=12.01, P=0.002). Respondents with different age ( H=6.49, P=0.039), occupation ( H=52.93, P<0.001) and educational level ( H=9.56, P=0.008)) had different needs for nursing and rehabilitation skills. Among the respondents, 58.2% (462/794) indicated that duration of each course should be 30-59 min, 34.0% (270/794) wanted to participate in the training once a month, 53.1% (422/794) wanted to participate in the training in the form of large class, 39.2% (311/794) were willing to participate in the training on working days and 48.7% (387/794) wanted to be trained in community health service institutions. Conclusions:There are diverse training needs of family health care workers. Attention should be paid to the implementation of need-oriented training. It is crucial to promote the motivation of family health care workers to participate in the training, which can improve the training effect and facilitate their role in family health management.

ABSTRACT

With the rapid development and wide application of next generation sequencing (NGS) technology, a series of researches have revealed that concurrent genetic alterations play an important role in the response and resistance of epidermal growth factor receptor (EGFR)-mutant NSCLC to EGFR-tyrosine kinase inhibitor (TKI). Besides, TP53 mutation is the most common co-mutation gene in EGFR-mutant NSCLC, which has been proved to confer a worse prognosis in EGFR-mutated patients treated with first, second and third generation of EGFR-TKIs. Currently, it is still being explored how to select the best treatment strategies for patients with concomitant presence of TP53 mutation in EGFR-mutant NSCLC. Here, we review the literature on recent research progress of TP53 concurrent mutation in EGFR-mutant advanced NSCLC.

ABSTRACT

Objective:To explore the clinical effects of Xingshen Tongqiao Huoxue decoction in the treatment of dysphagia caused by cricopharyngeal achalasia (CPA) after cerebral infarction and its influence on neurotransmitters. Method:One hundred and fourteen eligible patients were randomly divided into a control group (56 cases) and a treatment group (58 cases). Patients in both groups received balloon catheter dilatation and rehabilitation training. In the observation group, the Tiandan Tongluo capsules were further orally taken, five capsales per time, three times per day. In the control group, the Xingshen Tongqiao Huoxue decoction was provided, one dose per day. The treatment lasted for four weeks. Following the videofluoroscopic swallow study (VFSS) and water-swallowing test (WST) before and after treatment, the swallowing quality of life questionnaire (SWAL-QOL), functional oral intake scale (FOIS) and National Institutes of Health Stroke Scale (NIHSS) scores were calculated. The serum brain-derived neurotrophic factor (BDNF), substance P (SP), dopamine (DA), 5-hydroxytryptamine (5-HT) and nerve growth factor (NGF) levels before and after treatment were detected, and the complications were recorded. Result:The clinical efficacy of the treatment group was superior to that of the control group (<italic>Z</italic>=2.079, <italic>P</italic><0.05). Both VFSS and WST findings in the treatment group were milder than those in the control group (<italic>Z</italic>=2.004, <italic>P</italic><0.05 and <italic>Z</italic>=1.973, <italic>P</italic><0.05). The VFSS, SWAL-QOL, and FOIS scores and the BDNF, DA, SP, 5-HT and NGF levels of the treatment group were elevated in contrast to those of the control group (<italic>P</italic><0.01), whereas the NIHSS score declined (<italic>P</italic><0.01). The complication rate in the treatment group was (8/58) 13.79%, significantly lower than (17/56) 30.36% in the control group (<italic>χ</italic><sup>2</sup>=4.565, <italic>P</italic><0.05). Conclusion:On the basis of balloon catheter dilatation and rehabilitation training, the Xingshen Tongqiao Huoxue decoction can significantly enhance the swallowing function, improve the quality of life, and reduce complications in patients with dysphagia caused by CPA after cerebral stroke.

ABSTRACT

Metabolic syndrome (MS) is a group of syndromes caused by the disorder of metabolism of various substances in the body. The main clinical manifestations are dyslipidemia, central obesity, hypertension, abnormal glucose tolerance and insulin resistance. With the changes of diet structure and habits, the incidence rate of MS is increasing, and the patients are younger. It is an important factor in many diseases, such as diabetes, atherosclerosis, coronary heart disease, hyperlipidemia, cirrhosis and some cancers. MS has seriously affected people's lives and health. Central obesity and insulin resistance are recognized as important pathogenic factors. At present, the pathogenesis of MS and its components has not been fully understood. The clinical manifestations of metabolic syndrome are complex and diverse. Traditional Chinese medicine (TCM) believes that the occurrence of metabolic syndrome is related to such factors as proper diet, emotional disorders, excessive escape and little movement, old age and physical deficiency. TCM scholars have studied the pathogenesis of MS in such pathological factors as phlegm and blood stasis, such visceral functions as liver, spleen and kidney, roles of Qi and blood, and emotional factors. As the basic substance of organism, Qi is closely related to the process of metabolism. The occurrence of MS is closely related to the rise and fall of Qi moving to and from the body as well as the abnormal gasification function of the transformation of Qi. Qi is derived from the five internal organs, which are respectively called Heart Qi, liver Qi, spleen Qi, lung Qi and kidney Qi. The "Qi of the five internal organs" is involved in the whole process of the generation, transportation and excretion of the essence of the body. Based on the "Qi of five internal organs", this paper discusses the pathogenesis of MS with phlegm, blood stasis and water drink as pathological factors.

ABSTRACT

OBJECTIVE@#To study the value of serum procalcitonin (PCT) combined with soluble triggering receptor expressed on myeloid cells-1 (STREM-1) in the differential diagnosis of bacterial diarrhea and viral diarrhea in children.@*METHODS@#A retrospective analysis was performed on the medical data of 73 children with bacterial infectious diarrhea (bacteria group) and 68 children with viral infectious diarrhea (virus group) who were treated from February 2018 to May 2019. The receiver operating characteristic (ROC) curve was used to analyze the diagnostic efficacy of serum PCT and STREM-1 for bacterial infectious diarrhea and viral infectious diarrhea.@*RESULTS@#Compared with the virus group, the bacteria group had significantly higher detection rates of fecal red blood cells (79% vs 43%, P<0.05) and pus (51% vs 19%, P<0.05), as well as significantly higher serum levels of PCT and STREM-1 (P<0.05). The ROC curve analysis showed that in the differential diagnosis of bacterial infectious diarrhea and viral infectious diarrhea, serum PCT had a cut-off value of 0.97 ng/mL and an area under the ROC curve (AUC) of 0.792, and STREM-1 had a cut-off value of 15.66 ng/mL and an AUC of 0.889. Serum PCT combined with STREM-1 had an AUC of 0.955, which was significantly higher than that of each index alone (P<0.05).@*CONCLUSIONS@#Children with bacterial diarrhea have increased serum levels of PCT and STREM-1 than those with viral diarrhea. Both serum PCT and STREM-1 can be used as the indices for the differential diagnosis of bacterial diarrhea and viral diarrhea in children, and the combined measurement of PCT and STREM-1 can improve the efficiency of differential diagnosis.

ABSTRACT

Metastasis is the main reason that affects the survival and death of cancer patients. In recent years, it has been found that Rab25 is closely related to tumor invasion and metastasis. Rab25 has dual role in tumor metastasis, which can be used as oncogene or tumor suppressor gene. In most tumor types, Rab25 is an oncogene, and only in a few tumors, Rab25 shows tumor suppressor function. However, the dual action mechanism and signal pathway of Rab25 are not very clear. This article summarizes the related research on the role of Rab25 in tumor metastasis.

ABSTRACT

Objective:To investigate the renal protective effect of Tangshenping capsule (Tangshenping) on diabetic nephropathy (DN) KKAy mice and its effect on Wnt/β-catenin signaling pathway. Method:Sixty female Sprague-Dawley KKAy mice aged 10 weeks old were induced with KKAy rat feed for 10 weeks. The DN animal model was successfully determined with blood glucose (>16.7 mmol·L-1) and 24 hour urine protein (>0.4 mg). The model mice were randomly divided into a model group, an irbesartan group, and low, medium and high-dose Tangshenping group, with 10 female C57BL/6J mice as a control group. The treatment groups were given the corresponding drugs by gavage. The normal group and the model group were given an equal volume of deionized water by gavage. The intragastric dose was 0.01 mL·g-1 body weight coefficient once a day. The general conditions of the mice were observed, the body mass was weighed every 4 weeks, and 24 h urine protein was quantified. At the 26th week, the blood was collected from eyeballs, and the mice were put to death. The quality of the kidneys, serum blood urea nitrogen (BUN), serum creatinine (SCr), triglyceride (TG), malondialdehyde (MDA), nitric oxide (NO) and superoxide dismutase (SOD) content were measured. In situ hybridization and immunohistochemistry were used to detect the expressions of Wnt4, glycogen synthase kinase 3β(GSK3β) and β-catenin in kidney tissues. Result:Compared with model group, body mass, kidney mass/body mass, and 24 h urine protein were significantly lower in high-dose Tangshenping group (PPPβ and β-catenin were decreased (PConclusion:Tangshenping may inhibit the activation of Wnt/β-catenin signaling pathway, reverse the transdifferentiation of renal tubular epithelial cells in DN KKAy mice, delay the progression of renal interstitial fibrosis, and then exert renal protection.

ABSTRACT

Small-cell lung cancer (SCLC) has a high degree of malignancy and is characterized by strong invasiveness, rapid growth, and early metastasis. SCLC is sensitive to initial treatment with chemotherapy and radiotherapy, but it can easily relapse and has a poor prognosis. Both programmed death-1 (PD-1) and programmed cell death-ligand 1 (PD-L1) antagonists activate the immune response of tumor cells by activating T cells, and have shown exciting curative effects in clinical studies of SCLC, thereby becoming powerful po-tential agents to treat SCLC in the future. This article aims to illustrate the progress of PD-1/PD-L1 inhibitors in the treatment of SCLC, as well as the role of PD-L1 expression and tumor mutation burden (TMB) as a biomarker in SCLC.

ABSTRACT

Objective: In tumor microenvironment, immune-related mechanisms up-regulate the expression of programmed death li-gand 1 (PD-L1), which abnormally activates PD-L1 signaling pathway and mediates tumor immune escape. Soluble programmed death ligand 1 (sPD-L1) is a form of PD-L1. It has been confirmed that the expression of sPD-L1 in lung squamous cell carcinoma and adeno-carcinoma is related to disease progression, while small cell lung cancer (SCLC) has a high degree of malignancy, strong invasiveness and few related studies. The purpose of this study was to observe the changes in expression of sPD-L1 in the plasma of SCLC patients and their clinical significance. Methods: A total of 94 patients with SCLC diagnosed by pathological examination in Shanxi Provincial Cancer Hospital from March 2018 to November 2018 were selected as test group, and 17 healthy persons in the same period were se-lected as control group. The dynamic changes of plasma sPD-L1 were compared between the two groups, and the correlations among the expression of sPD-L1 and TNM stage, distant metastasis, and pro-gastrin-releasing peptide (ProGRP) was analyzed. Results: The lev-el of sPD-L1 in the test group was higher than that in the control group (P<0.05 and P<0.01, respectively). In patients with SCLC in the remission stage, the serum sPD-L1 level after chemotherapy was significantly lower than that before chemotherapy (P<0.01); in pa-tients with advanced stage, the serum sPD-L1 level after chemotherapy was significantly higher than that before chemotherapy (P<0.01). The abnormal high expression of sPD-L1 in SCLC patients was significantly correlated with the progression of the disease (P<0.05). The expression of sPD-L1 in serum was positively correlated with the tumor marker ProGRP. Conclusions: The expression of sPD-L1 in peripheral plasma of patients with SCLC is higher than that in healthy individuals and is closely related to the clinical effect.

ABSTRACT

Lung cancer is the most common malignant tumor worldwide. There are more than 700000 new cases diagnosed as lung cancer each year in China, of which 80%-85% are non-small cell lung cancer (NSCLC). The mutation proportion of epidermal growth factor receptor (EGFR) may reach up to 40%-55%. EGFR-tyrosine kinase inhibitor (EGFR-TKI) has become the standard first-line treatment method for advanced NSCLC patients with EGFR mutation. Chinese oncologists have done a large number of clinical studies, providing an important evidence-based medicine proof for treatment of advanced NSCLC with EGFR mutation.
