ABSTRACT

Background Affected by concentration, composition, and population tolerance of air pollutants, the relationship between air pollutants and population health has regional differences. There is still a research gap in Guiyang. Objective To explore the short-term effects of air pollutant concentrations in low-pollution areas on the outpatient volume of respiratory diseases. Methods Spearman correlation analysis was used to evaluate the correlation between air pollutants, meteorological factors, and respiratory outpatient volume from January 1, 2013 to December 31, 2020 in Guiyang City. A single pollutant distribution lag nonlinear model and a multi-pollutant interaction model were established based on Poisson distribution. A three-dimensional diagram was drawn to display the relationship between air pollutants and respiratory outpatient volume. Quantitative analysis was conducted on the attribution risk and lag effect of air pollutant concentration on outpatient volume of respiratory diseases in Guiyang City. Results The results of the single pollutant model showed that fine particulate matter (PM2.5), nitrogen dioxide (NO2), carbon monoxide (CO), and sulfur dioxide (SO2) elevated the outpatient volume of respiratory diseases. The maximum relative risk (RR) and 95%CI values of PM2.5, NO2,CO, and SO2 appeared on Day 2, 0, 5, and 6, respectively, which were 1.019 (1.015, 1.023), 1.146 (1.122, 1.171), 1.129 (1.116, 1.143), and 1.046(1.040, 1.052), respectively. For every quartile concentration increment of PM2.5, NO2, CO, or SO2, the outpatient volume of respiratory diseases increased by 0.943% (0.111%, 1.782%), 4.050% (3.573%, 4.529%), 0.595% (0.317%, 0.874%), or 0.667% (0.235%, 1.100%), respectively. The maximum RR (95%CI) of O3 was 1.015 (1.007, 1.023) and appeared on Day 0. The results of multi-pollutant model showed that PM2.5, NO2, CO, SO2, and O3 all elevated the outpatient volume of respiratory diseases. The maximum RR values of PM2.5, NO2, CO, SO2 and O3 appeared on Day 14, 0, 5, 7 and 0, respectively, which were 1.027 (1.021, 1.034), 1.213 (1.179, 1.248), 1.059 (1.043, 1.074), 1.016 (1.005, 1.026), and 1.024 (1.015, 1.033), respectively. Compared with the single pollutant model, the RR values of PM2.5, NO2, and O3 on the outpatient volume of respiratory diseases in the multi-pollutant model showed an upward trend, while the RR values of CO and SO2 in the multi-pollutant model showed a downward trend. Conclusion The impact of low concentrations of PM2.5, NO2, CO, and SO2 on human health cannot be ignored.

ABSTRACT

Objective: To evaluate the long-term efficacy and safety of the implantable ventricular assist system EVAHEART I in clinical use. Methods: Fifteen consecutive patients with end-stage heart failure who received left ventricular assist device therapy in Fuwai Hospital from January 2018 to December 2021 were enrolled in this study, their clinical data were retrospectively analyzed. Cardiac function, liver and kidney function, New York Heart Association (NYHA) classification, 6-minute walk distance and quality of life were evaluated before implantation and at 1, 6, 12, 24 and 36 months after device implantation. Drive cable infection, hemolysis, cerebrovascular events, mechanical failure, abnormally high-power consumption and abnormal pump flow were recorded during follow up. Results: All 15 patients were male, mean average age was (43.0±7.5) years, including 11 cases of dilated cardiomyopathy, 2 cases of ischemic cardiomyopathy, and 2 cases of valvular heart disease. All patients were hemodynamically stable on more than one intravenous vasoactive drugs, and 3 patients were supported by preoperative intra aortic balloon pump (IABP). Compared with before device implantation, left ventricular end-diastolic dimension (LVEDD) was significantly decreased ((80.93±6.69) mm vs. (63.73±6.31) mm, P<0.05), brain natriuretic peptide (BNP), total bilirubin and creatinine were also significantly decreased ((3 544.85±1 723.77) ng/L vs. (770.80±406.39) ng/L; (21.28±10.51) μmol/L vs. (17.39±7.68) μmol/L; (95.82±34.88) μmol/L vs. (77.32±43.81) μmol/L; P<0.05) at 1 week after device implantation. All patients in this group were in NYHA class Ⅳ before implantation, and 9 patients could recover to NYHA class Ⅲ, 3 to class Ⅱ, and 3 to class Ⅰ at 1 month after operation. All patients recovered to class Ⅰ-Ⅱ at 6 months after operation. The 6-minute walk distance, total quality of life and visual analogue scale were significantly increased and improved at 1 month after implantation compared with those before operation (P<0.05). All patients were implanted with EVAHEART I at speeds between 1 700-1 950 rpm, flow rates between 3.2-4.5 L/min, power consumption of 3-9 W. The 1-year, 2-year, and 3-year survival rates were 100%, 87%, and 80%, respectively. Three patients died of multiple organ failure at 412, 610, and 872 d after surgery, respectively. During long-term device carrying, 3 patients developed drive cable infection on 170, 220, and 475 d after surgery, respectively, and were cured by dressing change. One patient underwent heart transplantation at 155 d after surgery due to bacteremia. Three patients developed transient ischemic attack and 1 patient developed hemorrhagic stroke events, all cured without sequelae. Conclusion: EVAHEART I implantable left heart assist system can effectively treat critically ill patients with end-stage heart failure, can be carried for long-term life and significantly improve the survival rate, with clear clinical efficacy.

ABSTRACT

Objective:To investigate the effects of ceftriaxone(CTX) on nuclear factor erythroid 2-related factor 2(Nrf2)/glutathione peroxidase 4(GPX4) pathway and ferroptosis in early brain injury in rats with subarachnoid hemorrhage(SAH).Methods:Forty-eight clean grade male SD rats were randomly divided into sham operation group (Sham group), SAH group, SAH+ CTX group and SAH+ CTX+ Nrf2 inhibitor group (SAH+ CTX+ ML385 group) according to the random number table with 12 rats in each group.Seven days before modeling, rats in SAH+ CTX+ ML385 group were injected intraperitoneally with ML385 (30 mg · kg -1) once a day for consecutive 7 days.And 5 days before modeling, rats in SAH+ CTX group and SAH+ CTX+ ML385 group were treated with CTX(200 mg · kg -1) by intraperitoneal injection once a day for five consecutive days.Rats in Sham group and SAH group were intraperitoneally injected with the same amount of 0.9% sodium chloride solution.After 24 hours of modeling, the neurological function score and brain tissue water content of rats in each group were measured.HE staining was used to observe the morphology of neurons in CA1 and CA3 regions of hippocampus.Prussian blue staining was used to observe the iron deposition in cerebral cortex.Spectrophotometer was used to determine the iron content, malonic dialdehyde(MDA) content, glutathione(GSH) content and GPX4 activity in cerebral cortex.Western blot was used to detect the expression levels of Nrf2 and GPX4 proteins in cerebral cortex.SPSS 23.0 was used for statistical analysis.One-way ANOVA was used to compare the mean of multiple groups of samples, and Dunnett- t test was used for further pairwise comparison between groups. Results:There was a statistically significant difference in the neurological function scores of rats in the four groups 24 hours after SAH ( F=48.40, P<0.001). The neurological function score of rats in the SAH group 24 hours after SAH was significantly lower than those in Sham group and SAH+ CTX group (both P<0.05). The brain water content of rats in the four groups 24 h after SAH was statistically significant ( F=49.61, P<0.001). The brain water content of rats in the SAH group 24 h after SAH was significantly higher than that in Sham group and SAH+ CTX group(both P<0.05). There was statistically significant differences in the number of neuronal necrosis in CA1 and CA3 regions of hippocampus in the four groups 24 hours after SAH ( F=17.44, 246.50, both P<0.001). The numbers of neuronal necrosis in CA1 and CA3 regions of hippocampus in SAH group were significantly higher than those in Sham group and SAH+ CTX group, and the numbers of neuronal necrosis in CA1 and CA3 regions of hippocampus in SAH+ CTX+ ML385 group were significantly higher than those in SAH+ CTX group (all P<0.05). Twenty-four hours after SAH, the amount of iron deposited in the cerebral cortex of rats in the four groups was statistically significant ( F=2 363.0, P<0.001). The iron deposition in the cerebral cortex of rats in the SAH group was significantly higher than those in Sham group and SAH+ CTX group (both P<0.05). There were significant differences in iron content, MDA content, GSH content and GPX4 activity in the cerebral cortex of the four groups 24 h after SAH( F=2 380.0, 1 322.0, 789.1, 815.5, all P<0.001). The content of iron and MDA in the cerebral cortex of rats in SAH group were significantly higher than those in Sham group, while the content of GSH and the activity of GPX4 were significantly lower than those in Sham group (all P<0.05). The content of iron and MDA in the cerebral cortex of rats in SAH+ CTX group were lower than those in SAH group, and the content of GSH and the activity of GPX4 were higher than those in SAH group (all P<0.05). At 24 h after SAH, the expression levels of Nrf2 and GPX4 protein in the cerebral cortex of the four groups were statistically significant ( F=888.7, 1 556.0, both P<0.001). The protein expression levels of Nrf2 (0.382±0.014) and GPX4 (0.329±0.019) in the cerebral cortex in SAH group were lower than those in Sham group ((0.746±0.009), (0.953±0.009)) (both P<0.05). The expression levels of Nrf2 (0.631±0.006) and GPX4 (0.833±0.008) protein in the cerebral cortex in the SAH+ CTX group were significantly higher than those in the SAH group (both P<0.05). The expression levels of Nrf2 (0.427±0.009) and GPX4 (0.525±0.011) protein in the cerebral cortex in SAH+ CTX+ ML385 group were significantly lower than those in SAH+ CTX group (both P<0.05). Conclusion:Ceftriaxone may inhibit ferroptosis during EBI in SAH rats by regulating Nrf2/GPX4 signal axis.

ABSTRACT

Objective:To investigate the effects of low-frequency repetitive transcranial magnetic stimulation (rTMS) combined with music biofeedback on insomnia.Methods:Sixty patients with insomnia who received treatment in Outpatient Department of Seventh People's Hospital of Dongyang from January to August 2021 were included in this study. They were randomly divided into an observation group ( n = 30) and a control group ( n = 30) using the random number table. The control group was given music biofeedback therapy and conventional drug treatment, and the observation group was treated with rTMS based on music biofeedback therapy. The changes in polysomnography sleep structure and Pittsburgh Sleep Quality Index score after 1 month of treatment relative to before treatment were determined in each group. Results:After 1 month of treatment, the total sleep time, sleep efficiency, rapid eye movement (REM) sleep, non-REM sleep phase II (N2%) and non-REM sleep phase III (N3%) in the observation group were (419.87 ± 42.63) minutes, (83.69 ± 13.39)%, (25.27 ± 3.26)%, (53.75 ± 11.36)% and (16.27 ± 2.25)%, respectively, and they were (388.74 ± 40.39) minutes, (76.38 ± 13.17)%, (23.16 ± 2.68)%, (51.62 ± 12.27)%, and (14.36 ± 2.21)%, respectively. There were significant differences in these indices between the two groups ( t = -2.90, -2.13, -2.22, -2.26, -3.31, P = 0.005, 0.037, 0.030, 0.027, 0.002). The sleep latency, actual wake time, numbet of awakenings, non-REM sleep phase I (N1%), and total score of Pittsburgh Sleep Quality Index in the observation group were (24.16 ± 7.82) minutes, (23.18 ± 6.95) minutes, (1.76 ± 0.28) times, (9.74 ± 2.12)%, (9.17 ± 1.56) minutes, respectively. They were (28.35 ± 7.74) minutes, (28.36 ± 7.21) minutes, (2.25 ± 0.79) times, (11.12 ± 1.17)%, and (10.26 ± 1.42) minutes, respectively in the control group. There were significant differences in these indices between the two groups ( t = 2.09, 2.83, 3.20, 3.12, 2.83, P = 0.041, 0.006, 0.002, 0.003, 0.038).

ABSTRACT

【Objective:】 To explore the effect of metacognition on self-directed learning ability of undergraduate nursing students, and the role of interpersonal communication ability and sense of self-worth between them. 【Methods:】 A total of 905 undergraduate nursing students from six colleges and universities in Shaanxi were selected as the survey subjects by convenient sampling method during August to November 2022. Metacognitive Assessment Inventory, Self-Directed Learning Ability Measurement Scale for Nursing Students, Adolescent Sense of Total Self-Worth Scale, and Supportive Communication Scale were used to conduct a questionnaire survey on undergraduate nursing students. SPSS 25.0 software was used for statistical analysis of the data. 【Results:】 Finally, 854 valid questionnaires (94.36%) were collected, and the results showed that: a) Metacognition of undergraduate nursing students significantly positively predicted self-directed learning ability (β=0.172, P<0.001). b) Interpersonal communication ability played a partial mediating role between metacognition and self-directed learning ability [β=0.019, 95%CI: 0.004~0.034)] . c) The predictive effect of metacognition on self-directed learning ability was regulated by the level of self-worth (R2=0.314, P<0.001). 【Conclusion:】 This paper indicated that the metacognition of undergraduate nursing students indirectly affects their self-learning ability through interpersonal communication ability, and their sense of self-worth plays a moderating role. It is recommended to improve the metacognitive level of undergraduate nursing students, strengthen their interpersonal communication skills, and focus on the cultivation of self-worth, so as to improve their self-directed learning ability.

ABSTRACT

Objective:To explore the prognostic prediction value of quantitative digital subtraction angiography (DSA) parameters in patients with acute anterior circulation ischemic stroke undergoing mechanical thrombectomy, and whether the clinical values vary by stroke etiology.Methods:This study was a post hoc analysis of the Multicenter Prospective Captor Trial. Patients with acute anterior circulation large-vessel occlusion and successful recanalization from April 2018 to July 2019 were screened. Post-processing analysis was performed on the DSA imaging sequence after recanalization, and 4 regions of interest (ROI) were selected in the target vessel: ROI1 (the proximal of the internal carotid artery-C2 segment), ROI2 (the starting point of the internal carotid artery-C7 segment), ROI3 (the end of the middle cerebral artery-M1 segment), and ROI4 (the end of the middle cerebral artery-M2 segment). Time to peak (TTP) was defined as the time at contrast concentration of selected ROI reached its maximum. Relative TTP (rTTP) was calculated by subtracting the TTP of ROI1 from the TTP of distalis ROIs. Successful recanalization was defined as modified Thrombolysis In Cerebral Infarction (mTICI) grade≥2b. Favorable outcomes at 3 months were defined as the modified Rankin Scale score≤2. According to the modified Rankin Scale score, the patients were divided into good prognosis group and poor prognosis group. The differences in clinical characteristics, postoperative hemodynamic parameters, and other data were compared between patients with good and poor prognoses. Univariate and multivariate Logistic regression was used to analyze factors related to a good prognosis. Finally, the prognostic prediction value of hemodynamic parameters was analyzed in patients with different Trial of Org10172 in Acute Stroke Treatment etiological classifications.Results:A total of 245 patients were collected, of which 161 patients [age 69 (60, 76) years, 92 (57.1%) male] were finally included in the analysis, including 36 cases of large artery atherosclerosis (LAA) stroke, 76 cases of cardiogenic embolism (CE), and 49 cases of other causes of stroke. Seventy-one (44.1%) patients had favorable outcomes at 3 months. The post-operative hemodynamic analysis indicated that patients with favorable outcomes ( n=71) had a higher proportion of mTICI grade 3 [54/71 (76.1%) vs 41/90 (45.6%),χ 2=15.26, P<0.001] and lower rTTP 31 [means TTP ROI3-TTP ROI1;0.33 (0.23, 0.54) s vs 0.47 (0.31, 0.65) s, Z=-2.71, P=0.007] than patients with unfavorable outcomes ( n=90). The mTICI score and rTTP 31 were respectively included in multivariate Logistic regression models. It was shown that mTICI grade 3 (adjusted OR=5.97, 95% CI 2.49-14.27, P<0.001) and rTTP 31 (adjusted OR=0.24, 95% CI 0.06-0.99, P=0.048) were significantly associated with favorable outcomes, and the area under the receiver operating characteristic curve of the models had no statistically significant difference ( P=0.170). Subgroup analysis showed that rTTP 31 was significantly associated with the prognosis of patients with LAA stroke ( OR=0, 95% CI 0-0.25, P=0.014), while mTICI grade was associated with the prognosis of patients with CE ( OR=3.91, 95% CI 1.40-10.91, P=0.009) and other etiologies ( OR=7.35, 95% CI 1.92-28.14, P=0.004). Conclusions:In patients with acute anterior circulation ischemic stroke and successful recanalization, both mTICI score and rTTP 31 had significant predictive value for favorable outcomes at 3 months. Moreover, rTTP 31 was significantly associated with the prognosis of patients with LAA stroke, while mTICI score was significantly related to the prognosis of patients with CE and other causes of stroke.

ABSTRACT

Objective:To explore the effect of patient engagement on medication safety for patients with chronic disease through a systematic review.Methods:Relevant randomized controlled trials of patient engagement on medication safety were searched from PubMed, EMBASE, The Cochrane Library, CNKI, Wanfang and VIP database. The literature was screened according to inclusion and exclusion criteria, and data extraction and literature quality evaluation was conducted on the selected literature.Results:A total of 15 eligible studies was included. Most of the studies occurred in outpatient and home settings, and the subjects were patients with chronic diseases. Patient engagement strategies can be divided into three categories: (1) patient engagement in medical decision-making; (2) patient engagement in medication adjustment; (3) patient engagement in medication management. The outcomes of medication safety included medication adherence, medication knowledge, medication beliefs, adverse events and medication errors. Intervention strategies for patients to actively engage in medication safety significantly improved patients′ medication knowledge and beliefs, but did not improve medication adherence of patients.Conclusion:Promoting patient active engagement is an effective intervention measure to improve patients ′ perception of medication safety. Due to the limited quality and quantity of the included studies, more high-quality studies are needed to verify the above conclusions.

ABSTRACT

AIM: To compare the thickness of retina in macular area and retinal nerve fiber layer(RNFL)around optic disc between the eyes of monocular anisometropic amblyopia children and normal eyes.METHODS: A total of 62 children(124 eyes)with monocular anisometropic amblyopia who were treated in Chengdu Women's and Children's Central Hospital from January 2021 to October 2022 were selected as the experimental group, and 60 children(60 eyes; right eye)with normal vision who were treated in the same period were selected as the control group. Spectral-domain optical coherence tomography(SD-OCT)was used to detect the retinal thickness in macular region and the RNFL thickness around optic disc in the two groups, and comparative analysis was performed.RESULTS: The retinal thickness and perioptic RNFL thickness of amblyopic children in experimental group were thicker than those in control group, and most of them had significant differences(P&#x003C;0.05). The retinal thickness and perioptic RNFL thickness of contralateral non-amblyopic children in experimental group were thinner than those in control group, but there were no significant differences in most of them(P&#x003E;0.05).CONCLUSIONS: There are differences in the retinal thickness of the macula and perioptic RNFL in the amblyopic eye and the contralateral non-amblyopic eye of monocular anisometropic amblyopic children compared with normal eyes, and the contralateral non-amblyopic eye is not completely equal to the normal eye.

ABSTRACT

The global COVID-19 coronavirus pandemic has infected over 109 million people, leading to over 2 million deaths up to date and still lacking of effective drugs for patient treatment. Here, we screened about 1.8 million small molecules against the main protease (Mpro) and papain like protease (PLpro), two major proteases in severe acute respiratory syndrome-coronavirus 2 genome, and identified 1851Mpro inhibitors and 205 PLpro inhibitors with low nmol/l activity of the best hits. Among these inhibitors, eight small molecules showed dual inhibition effects on both Mpro and PLpro, exhibiting potential as better candidates for COVID-19 treatment. The best inhibitors of each protease were tested in antiviral assay, with over 40% of Mpro inhibitors and over 20% of PLpro inhibitors showing high potency in viral inhibition with low cytotoxicity. The X-ray crystal structure of SARS-CoV-2 Mpro in complex with its potent inhibitor 4a was determined at 1.8 Å resolution. Together with docking assays, our results provide a comprehensive resource for future research on anti-SARS-CoV-2 drug development.

ABSTRACT

Objective:To systematically evaluate the safety of family integrated care (FICare) model in neonatal intensive care unit (NICU).Methods:Multiple medical databases were searched for clinical studies on FICare in NICU published from January 1, 2010 to May 28, 2022. The quality of the literature was evaluated using Risk?of?Bias?2 tool?and cohort evaluation criteria from the Cochrane Systematic Evaluation Manual depending on the types of studies included. Meta-analysis was performed using Review Manager 5.3 software.Results:Six randomized controlled trials and four cohort studies were included for meta-analysis. The results of meta-analysis showed that compared with the traditional care model, FICare model did not increase the risk of nosocomial infection ( RR=0.75, 95% CI 0.46-1.24, P=0.27) and unstable medical conditions ( RR=0.86, 95% CI 0.61-1.22, P=0.40). No significant difference existed in the all-cause mortality between FICare and traditional care ( RR=2.74, 95% CI 0.88-8.57, P=0.08). Conclusions:FICare does not increase the risk of nosocomial infection, unstable medical conditions and adverse events compared with traditional care. It is safe and feasible to implement FICare in NICU.

ABSTRACT

Objective:To study the genetic profiles and clinical characteristics of neonatal-onset genetic epilepsy.Methods:From July 2016 to May 2021, patients with neonatal-onset genetic epilepsy admitted to our hospital and received second-generation genetic sequencing were enrolled in this study. According to the types of genetic variations, the patients were assigned into ion channel group and non-ion channel group. Clinical characteristics, treatments and prognosis of the two groups were compared.Results:A total of 36 patients with identified genetic variations were enrolled, involving 15 epilepsy-related genes. KCNQ2, SCN2A and STXBP1 were the most common pathogenic genes. 20 cases (55.6%) were in the ion channel group and 16 cases (44.4%) in the non-ion channel group. No significant differences existed in their general status, seizure types, EEG characteristics, treatments and outcomes between the two groups ( P>0.05). Among all 36 cases, the age of onset ranged from 10 min to 24 d after birth and 28 cases (78.8%) developed epilepsy within 1 week after birth. Developmental and epileptic encephalopathies were diagnosed in 20 patients. 7 patients were diagnosed with self-limited neonatal epilepsy, 2 were pyridoxine dependence, 2 were Zellweger syndrome and 1 case of self-limited familial neonatal-infantile epilepsy, Turner type mental retardation with epilepsy, PURA syndrome, Rett syndrome and 22q11.2 deletion syndrome, each. The patients received antiepileptic drugs including phenobarbital, levetiracetam, oxcarbazepine, topiramate, valproic acid, benzodiazepines (nizepam/clonazepam /clobazam/midazolam), lacosamide and lamotrigine. 5 patients died after giving up treatment. 31 patients were followed up for 6 to 50 months. 22 cases (71.0%) were controlled at 1- to 35-month-old including 21 cases (56.7%) with developmental delay. 6 cases (19.4%) had ineffective seizure control and 3 cases (9.7%) showed reduced seizures, all with varying degrees of developmental delay. Conclusions:Neonatal-onset epilepsy is correlated with multiple genes. KCNQ2, SCN2A, STXBP1 are the common pathogenic genes with multiple variants of KCNQ2 gene. Most patients have seizures within 1 week after birth. More than half of patients have ion channel related gene variations. Sodium channel blockers have certain effects as treatment.

ABSTRACT

Objective:To investigate the clinical efficacy of radical resection of pancreatic cancer after neoadjuvant conversion therapy.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 23 patients who underwent radical resection of pancreatic cancer after neoadjuvant conversion therapy in Nanjing Drum Tower Hospital Affiliated to Nanjing University Medical School from January 2019 to May 2022 were collected. There were 17 males and 6 females, aged 58(range, 33-73)years. After neoadjuvant conversion therapy, the three-dimensional (3D) visualization was used to evaluate and classify tumor vascular invasion, and surgical plan was planned and implemented. Observation indicators: (1) situations of neoadjuvant conversion therapy; (2) surgical situations; (3) postoperative histopathological examination; (4) postoperative recovery; (5) follow-up. Measurement data with normal distribution were represen-ted as Mean± SD, and measurement data with skewed distribution were represented as M(range) or M( Q1, Q3). Count data were described as absolute numbers. Results:(1) Situations of neoadjuvant conversion therapy. All 23 patients received the AG combination chemotherapy (albumin-paclitaxel+gemcitabine), including 14 patients combined with stereotactic body radiation therapy. Of the 23 patients, 22 cases achieved partial response, and 1 case showed stable disease.

ABSTRACT

Objective:To analyze the status of the dyadic coping in spouses of young and middle-age cervical cancer patients undergoing synchronous radiotherapy and chemotherapy, and to explore the influencing factors in bi-directional of patients and their spouses.Methods:With the convenience sampling method, a total of 150 cervical cancer patients undergoing synchronous radiotherapy and chemotherapy who were hospitalized in the Radiotherapy Department of Tianjin Medical University Cancer Institute and Hospital from March 2021 to February 2022 and their spouses were selected. A cross-sectional study was conducted by the Dyadic Coping Inventory, the Lock-Wallace Marital Adjustment Test, the General Self-Efficacy Scale, the Hospital Anxiety and Depression Scale, etc. Besides, multiple linear regression was used to identify predictors of the dyadic coping in spouses of cervical cancer patients undergoing synchronous radiotherapy and chemotherapy.Results:The total score of dyadic coping, marital quality, general self-efficacy, anxiety and depression in spouses of cervical cancer patients undergoing synchronous radiotherapy and chemotherapy were (121.69 ± 19.67), (97.23 ± 25.05), (25.13 ± 5.19), (9.98 ± 3.46), (8.19 ± 4.06) points. The scores of anxiety and depression of cervical cancer patients undergoing synchronous radiotherapy and chemotherapy were (10.57 ± 3.60), (9.10 ± 4.12) points. Multiple linear regression analysis showed that factors of the patients′ anxiety and depression, spouse′s perception of marital quality, spouse′s general self-efficacy, changes in family relationship, family income, and period of radiotherapy were the main influencing factors ( P<0.01), which accounted for 55.7% of total variation. Conclusions:The level of dyadic coping in spouses of cervical cancer patients undergoing synchronous radiotherapy and chemotherapy was medium, the marriage quality remains to be further improved,and its influence factors involved in the bi-directional of patient and spouse, including patients′ anxiety and depression, the changes of the family relationship, period of radiotherapy, spouses perception of marital quality and self-efficacy and family income. Clinical medical staff can improve the level of dyadic coping in spouses of cervical cancer patients undergoing synchronous radiotherapy and chemotherapy by improving their cognition of disease, reducing the incongruence of dyadic illness appraisals, and taking multiple measures to reduce the economic burden felt of the spouses.

ABSTRACT

Objective:To evaluate the curative effect of self-made Xingqi Jiedu Decoction combined with goserelin for endometriosis (EMT).Methods:Randomized controlled trial. A total of 84 patients with EMT in the hospital were enrolled as observation objects between July 2019 and July 2021. According to random number table method, they were divided into the control group (subcutaneous injection of goserelin) and the observation group (self-made Xingqi Jiedu Decoction on basis of control group), 42 in each group. All were treated for 6 months. TCM syndromes were scored before and after treatment. The severity of pelvic pain was evaluated by VAS. The levels of FSH, LH and estradiol (E 2) were detected by full-automatic chemiluminescence immunoassay and corresponding reagents, and levels of serum IL-1β, IL-8 and TNF-α were detected by ELISA. The adverse events were recorded, and clinical curative effect was evaluated. Results:The differences in total response rate between observation group and control group was statistically significant [95.24% (40/42) vs. 80.95% (34/42); χ2=4.09, P=0.043]. After treatment, scores of TCM syndromes and VAS in observation group were significantly lower than those in the control group ( t=14.30, 7.32, P<0.01). After treatment, FSH [(5.36±1.03) U/L vs. (6.20±1.35) U/L, t=3.21], E 2[(230.57±36.84) pmol/L vs. (265.28±37.53) pmol/L, t=4.28] and LH [(8.15±1.18) U/L vs. (9.24±2.01) U/L, t=3.03] in the observation group were significantly lower than those in the control group ( P<0.01). The levels of IL-1β, IL-8 and TNF-α in the observation group were significantly lower than those in the control group ( t=5.05, 5.07, 3.82, P<0.01). During treatment, differences in incidence of adverse reactions between observation group and control group was statistically significant [19.05% (8/42) vs. 4.76% (2/42); χ2=4.09, P=0.043]. Conclusion:The self-made Xingqi Jiedu Decoction combined with goserelin can improve hormone level, inhibit inflammatory response and improve clinical curative effect in EMT patients.

ABSTRACT

Objective:To explore the clinical characteristics, treatment regimens and prognostic influencing factors of patients with multiple myeloma (MM) involving central nervous system (CNS).Methods:The clinical data of 18 MM patients involving CNS in Second Affiliated Hospital of Naval Medical University from January 2014 to June 2020 were retrospectively analyzed. Their clinical characteristics, treatment and prognosis were also analyzed. Kaplan-Meier method was used to make survival analysis and log-rank was performed; Cox proportional risk model was used to make univariate and multivariate analysis.Results:The cohort of 18 patients included 12 males and 6 females; the median age of patients involving CNS was 54 years (38-71 years). The median time from diagnosis to the involvement of CNS was 22 months (0-126 months).Among 18 patients, 1 case was primary MM involving CNS, and 17 cases were secondary MM involving CNS. All patients had Durie-Salmon (DS) stage Ⅲ; 10 cases had international staging system (ISS) stage Ⅲ, 6 cases had ISS stage Ⅱ, and 2 cases had ISS stage Ⅰ. Involvement sites of CNS included 7 cases of involving the dura mater alone and 4 cases of involving the pia mater alone, 2 cases of involving brain parenchyma and 5 cases of involving both meninges and brain parenchyma. The most common neurological symptoms were headache and cranial nerve palsy, and 9 patients had multiple neurological symptoms. All patients received systemic therapy, 16 patients received an intrathecal injection and/or radiotherapy; and the overall effective rate was 66.7%, including 3 achieving strict complete remission (sCR), 1 achieving complete remission (CR), 3 achieving very good partial remission (VGPR), 5 achieving partial remission (PR). The median overall survival (OS) was 32.7 months. Counting from the point of CNS involvement, the median progression-free survival (PFS) and OS time was 7.5 months, 12.2 months, respectively. The median PFS of MM patients in the dura-involved alone group was longer than that in the non-dura-involved alone group (15.1 months vs. 5.9 months, P = 0.009); the median OS of MM patients in the dura-involved alone group was longer than that in the non-dura-involved alone group (16.9 months vs. 10.7 months, P = 0.175). Multivariate Cox analysis showed that dura mater involvement alone was an independent factor affecting PFS in MM patients with CNS involvement ( HR = 0.191,95% CI 0.038-0.952, P = 0.043). Conclusions:MM involving CNS is rarely found and has a very poor prognosis. Different sites of CNS involvement could affect the prognosis of patients. There is a lack of effective treatment regimens.

ABSTRACT

OBJECTIVE@#The activation of Janus kinase (JAK) and signal transducers and activators of transcription (STAT) plays an important role in the prognosis and targeted therapy of ovarian high-grade serous carcinoma (HGSC). Utilizing simple and practicable technique, this study aimed to evaluate the activation of JAK/STAT signaling pathway in ovarian HGSC patients, and investigated the correlation between the activation of JAK/STAT signaling pathway and the prognosis of the HGSC patients.@*METHODS@#We performed immunohistochemistry of phosphorylated STAT3 (pSTAT3) and phosphorylated STAT5 (pSTAT5) on paraffin imbedded slides of 73 ovarian HGSC patients, and evaluated the expression level and range of both markers. According to the grading score of the immunostaining of pSTAT3 and pSTAT5, we divided the 73 ovarian HGSC cases into STAT3 low/high expression and STAT5 low/high expression groups, and analyzed the prognosis of the patients in different groups, in order to explore the relationship between the expression of pSTAT3 and pSTAT5 proteins and the prognosis of the HGSC patients.@*RESULTS@#Some of the ovarian HGSC cases showed high expression of pSTAT3 and pSTAT5 protein level, which was related to the poorer prognosis of the HGSC patients. There was a significant difference in the expression level of pSTAT3 and pSTAT5 between the patients with better prognosis (survival time ≥3 years) and poorer prognosis (survival time < 3 years). The patients with higher protein expression of pSTAT3, pSTAT5 or both markers might have poorer prognosis, with significant shorter progression-free survival time and overall survival time (P < 0.001).@*CONCLUSION@#Immunostaining of pSTAT3 and pSTAT5 proteins might be helpful to evaluate and predict the prognosis of the ovarian HGSC patients, and to identify the patients who might have higher chances to respond to the STAT inhibitors and anti-angiogenesis therapy.

ABSTRACT

Objective: To compare the dwelling time and complications of low lying umbilical venous catheterization (UVC) in preterm infants with that of central UVC. Methods: This was a prospective cohort study. A total of 3 020 preterm infants from 44 neonatal intensive care units (NICU) who had UVC inserted from October 2019 to August 2021 were enrolled. Demographic and general baseline data, dwelling time of UVC and reasons for removal, complications and their occurrence time were collected. According to the position of the catheter tip, the preterm infants were divided into low lying UVC group (insertion depth of 3-5 cm) and central UVC group (the catheter tip was close to the entrance of right atrium, or at the 8th-9th thoracic vertebra level). The Mann-Whitney U test was used to compare the dwelling time and incidence of complications (cases/1 000 catheter days), and the independent t test and Chi-square test were used to compare the characteristics between the 2 groups. The receiver operating characteristic (ROC) curve was used to analyze the optimal cut-off value of UVC dwelling time. Results: Among the included 3 020 preterm infants, 1 624 (53.8%) were males, the gestational age was 29.9 (28.4, 31.6) weeks, the birth weight was (1 264±301) g, and 2 172 (71.9%) premature babies had central UVC. There were no significant differences in the proportion of males, the gestational age and the birth weight of neonates between the 2 groups (all P>0.05). There were also no significant differences in the rate of maternal history, PPROM>18 hours, chorioamnionitis, antenatal antibacterial angents exposure and antibacterial angents usage through UVC (all P>0.05). The dwelling time of central UVC was longer than that of low lying UVC (7 (6, 10) vs. 4 (3, 7) days, U=23.42, P<0.001). The complication incidence of central and low lying UVC were 20.0 and 70.8 cases/1 000 catheter days, respectively. The top 3 complications of central UVC were occlusion, catheter tip migration, and CLABSI (9.3, 3.5, 3.0 cases/1 000 catheter days). The top 3 complications of low lying UVC were catheter occlusion, CLABSI, and catheter tip migration (45.8, 6.3, 5.4 cases/1 000 catheter days). The ROC curve of UVC dwelling time and complications showed that the cut-off values ​​of central UVC and low lying UVC were 6.5 and 4.5 days, respectively. The 2 groups both showed a trend of increases in the 3 complications with the prolonged dwelling time. Cox regression analysis showed that the overall difference in the proportion of occlusion between the central UVC and low lying UVC groups was statistically significant (χ2=30.18, P=0.024). There were both no significant differences in catheter tip migration and CLABSI (both P>0.05). Conclusions: The most common UVC complication in preterm infants is occlusion. It is not recommended to keep a low lying UVC for longer than 4.5 days. During the whole dwelling period, a close monitoring for UVC complications is required.

ABSTRACT

PURPOSE@#This study aims to elucidate the electrotaxis response of alveolar epithelial cells (AECs) in direct-current electric fields (EFs), explore the impact of EFs on the cell fate of AECs, and lay the foundation for future exploitation of EFs for the treatment of acute lung injury.@*METHODS@#AECs were extracted from rat lung tissues using magnetic-activated cell sorting. To elucidate the electrotaxis responses of AECs, different voltages of EFs (0, 50, 100, and 200 mV/mm) were applied to two types of AECs, respectively. Cell migrations were recorded and trajectories were pooled to better demonstrate cellular activities through graphs. Cell directionality was calculated as the cosine value of the angle formed by the EF vector and cell migration. To further demonstrate the impact of EFs on the pulmonary tissue, the human bronchial epithelial cells transformed with Ad12-SV40 2B (BEAS-2B cells) were obtained and experimented under the same conditions as AECs. To determine the influence on cell fate, cells underwent electric stimulation were collected to perform Western blot analysis.@*RESULTS@#The successful separation and culturing of AECs were confirmed through immunofluorescence staining. Compared with the control, AECs in EFs demonstrated a significant directionality in a voltage-dependent way. In general, type Ⅰ alveolar epithelial cells migrated faster than type Ⅱ alveolar epithelial cells, and under EFs, these two types of cells exhibited different response threshold. For type Ⅱ alveolar epithelial cells, only EFs at 200 mV/mm resulted a significant difference to the velocity, whereas for, EFs at both 100 mV/mm and 200 mV/mm gave rise to a significant difference. Western blotting suggested that EFs led to an increased expression of a AKT and myeloid leukemia 1 and a decreased expression of Bcl-2-associated X protein and Bcl-2-like protein 11.@*CONCLUSION@#EFs could guide and accelerate the directional migration of AECs and exert antiapoptotic effects, which indicated that EFs are important biophysical signals in the re-epithelialization of alveolar epithelium in lung injury.

ABSTRACT

OBJECTIVE@#To explore the genetic basis for 7 families with gonadal mosaicism for Duchenne muscular dystrophy (DMD).@*METHODS@#For the 7 families presented at the CITIC Xiangya Reproductive and Genetic Hospital from September 2014 to March 2022, clinical data were collected. Preimplantation genetic testing for monogenic disorders (PGT-M) was carried out for the mother of the proband from family 6. Peripheral venous blood samples of the probands, their mothers and other patients from the families, amniotic fluid samples from families 1 ~ 4 and biopsied cells of embryos cultured in vitro from family 6 were collected for the extraction of genomic DNA. Multiplex ligation-dependent probe amplification (MLPA) was carried out for the DMD gene, and short tandem repeat (STR)/single nucleotide polymorphism (SNP)-based haplotypes were constructed for the probands, other patients, fetuses and embryos.@*RESULTS@#The results of MLPA showed that the probands and the fetuses/probands' brothers in families 1 ~ 4, 5, 7 had carried the same DMD gene variants, whilst the probands' mothers were all normal. The proband in family 6 carried the same DMD gene variant with only 1 embryo (9 in total) cultured in vitro, and the DMD gene of the proband's mother and the fetus obtained through the PGT-M were normal. STR-based haplotype analysis showed that the probands and the fetuses/probands' brothers in families 1 ~ 3 and 5 have inherited the same maternal X chromosome. SNP-based haplotype analysis showed that the proband from family 6 has inherited the same maternal X chromosome with only 1 embryo (9 in total) cultured in vitro. The fetuses in families 1 and 6 (via PGT-M) were both confirmed to be healthy by follow up, whilst the mothers from families 2 and 3 had chosen induced labor.@*CONCLUSION@#Haplotype analysis based on STR/SNP is an effective method for judging gonad mosaicism. Gonad mosaicisms should be suspected for women who have given births to children with DMD gene variants but with a normal peripheral blood genotype. Prenatal diagnosis and reproductive intervention may be adapted to reduce the births of further affected children in such families.

ABSTRACT

【Objective】 To explore the status quo and influencing factors of knowledge, attitude and practice of voluntary blood donation among undergraduates in Beijing. 【Methods】 A questionnaire was designed on the basis of literature, using the method of convenience sampling to survey the undergraduates from 39 universities in Beijing. The t-test, analysis of variance and χ2 test were used to compare the differences in knowledge, attitude and practice of voluntary blood donation among different groups, and logistic regression model was performed to analyze the influencing factors. 【Results】 A total of 1 075 valid questionnaires were collected from undergraduates of 39 universities in Beijing. The results showed that the proportion of the participants who had good knowledge about voluntary blood donation was 69.21% (744/1 075). No statistically significant difference was noticed on the scores of voluntary blood donation knowledge between males and females (P>0.05). The scores of voluntary blood donation knowledge of medical students were higher than those of other subjects (P<0.05). The scores of voluntary blood donation knowledge of juniors and above were higher than those of lower grades (P<0.05). The rate of undergraduates participating voluntary blood donation in Beijing was 30.98% (333/1 075). A total of 67.26% (723/1 075) of students had donation intention, 9.49% (102/1 075) didn’t and 23.25% (250/1 075) were not sure. No statistically significant differences in blood donation intention were observed among undergraduates by genders and grades (P>0.05). The rate of medical students’ intention to donate blood was higher than that of other subjects (P<0.05). 【Conclusion】 The rate of voluntary blood donation among undergraduates in Beijing was above the middle level compared with other regions in China, but the practice of voluntary blood donation is far away from the intention. Therefore, it’s necessary to improve the level of knowledge, attitude and practice of undergraduates, especially non-medical college students, so as to improve the rate of voluntary blood donation among the undergraduates in Beijing.
