Objective:To investigate the influencing factors for microvascular invasion (MVI) in hepatocellular carcinoma based on three-dimensional visualization and the construction of its nomogram model.Methods:The retrospective cohort study method was conducted. The clinico-pathological data of 190 patients with hepatocellular carcinoma who were admitted to Henan University People′s Hospital from May 2018 to May 2021 were collected. There were 148 males and 42 females, aged (58±12)years. The 190 patients were randomly divided into the training set of 133 cases and the validation set of 57 cases by the method of random number table in the ratio of 7:3. The abdominal three-dimensional visualization system was used to characterize the tumor morphology and other imaging features. Observation indicators: (1) analysis of influencing factors for MVI in hepatocellular carcinoma; (2) construction and evaluation of nomogram model of MVI in hepatocellular carcinoma. Measurement data with normal distribution were expressed as Mean± SD, and independent sample t test was used for comparison between groups. Measurement data with skewed distribution were expressed as M( Q1, Q3), and non-parametric rank sum test was used for comparison between groups. Count data were expressed as absolute numbers, and the chi-square test was used for comparison between groups. Corresponding statistical methods were used for univariate analysis. Binary Logistic regression model was used for multivariate analysis. Receiver operator characteristic (ROC) curves were plotted, and the nomogram model was assessed by area under the curve (AUC), calibration curve, and decision curve. Results:(1) Analysis of influencing factors for MVI in hepatocellular carcinoma. Among 190 patients with hepatocellular carcinoma, there were 97 cases of positive MVI (including 63 cases in the training set and 34 cases in the validation set) and 93 cases of negative MVI (including 70 cases in the training set and 23 cases in the validation set). Results of multivariate analysis showed that alpha-fetoprotein, vascular endothelial growth factor, tumor volume, the number of tumors, and tumor morphology were independent factors affecting the MVI of patients with hepatocellular carcinoma ( odds ratio=5.06, 3.62, 1.00, 2.02, 2.59, 95% confidence interval as 1.61-15.90, 1.28-10.20, 1.00-1.01, 1.02-3.98, 1.03-6.52, P<0.05). (2) Construction and evaluation of nomogram model of MVI in hepatocellular carcinoma. The results of multivariate analysis were incorporated to construct a nomogram prediction model for MVI of hepatocellular carcinoma. ROC curves showed that the AUC of the training set of nomogram model was 0.85 (95% confidence interval as 0.79-0.92), the optimal fractional cutoff based on the Jordon′s index was 0.51, the sensitivity was 0.71, and the specificity was 0.84. The above indicators of validation set were 0.92 (95% confidence interval as 0.85-0.99), 0.50, 0.90, and 0.82, respectively. The higher total score of the training set suggested a higher risk of MVI in hepatocellular carcinoma. The calibration curves of both training and validation sets of nomogram model fitted well with the standard curves and have a high degree of calibration. The decision curve showed a high net gain of nomogram model. Conclusions:Alpha-fetoprotein, vascular endothelial growth factor, tumor volume, the number of tumors, and tumor morphology are independent influencing factors for MVI in patients with hepatocellular carcinoma. A nomogram model constructed based on three-dimensional visualized imaging features can predict MVI in hepatocellular carcinoma.

Objective:To investigate the effects of early percutaneous coronary intervention (PCI) on myocardial perfusion and left ventricular function in patients with acute ST-segment elevation myocardial infarction (STEMI) after thrombolysis.Methods:A total of 108 patients with STEMI treated in the Second Hospital of Hebei Medical University from January 2020 to December 2022 were divided into early PCI following thrombolysis group ( n=65) and primary PCI (pPCI) group ( n=43). The general clinical data, and the parameters of routine echocardiography at 1 day after PCI and before discharge were compared between the two groups. Myocardial contrast echocardiography (MCE) was used to evaluate myocardial perfusion at 1 day after PCI and before discharge. Results:There were no significant differences in general clinical data between the early PCI following thrombolysis group and the pPCI group (all P>0.05). The left ventricular ejection fraction (LVEF) in the early PCI following thrombolysis group and pPCI group before discharge was significantly higher than that on the 1st day after PCI(both P<0.05). The difference of LVEF was significant between the early PCI following thrombolysis group and the pPCI group before discharge and 1 day after PCI ( P<0.05). Compared with 1 day after PCI, the global longitudinal strain (LVGLS) of left ventricle increased in early PCI following thrombolysis group and pPCI group before discharge(both P<0.05). The difference of LVGLS between early PCI following thrombolysis group and pPCI group before discharge and 1 day after discharge was statistically significant( P<0.05). There were no significant differences in left ventricular end-diastolic diameter (LVEDD), left ventricular end-diastolic volume (LVEDV), left atrial volume (LAV), ratio of mitral early diastolic velocity to late diastolic velocity (E/A), mean early diastolic velocity of mitral annulus (Em) and E/Em 1 day after PCI and before discharge between early PCI following thrombolysis group and pPCI group (all P>0.05). MCE showed that the MCE score index of early PCI following thrombolysis group and pPCI group before discharge was significantly lower than that of 1 day after PCI(both P<0.001). Compared to the 1 day after PCI, the early PCI following thrombolysis group showed a significant increase in the proportion of normal microvascular perfusion (nMVP) and a decrease in the proportion of delayed microvascular perfusion (dMVP) and microvascular obstruction (MVO) before discharge (all P<0.05). In contrast, the pPCI group demonstrated a significant decrease in the proportion of both nMVP and dMVP before discharge compared to the first day after PCI (all P<0.05). However, the decrease in the proportion of MVO was not statistically significant ( P>0.05). Conclusions:Early PCI following thrombolysis and pPCI can enhance left ventricular systolic function and myocardial perfusion in patients with acute ST-elevation myocardial infarction. Early PCI following thrombolysis may offer additional advantages in improving left ventricular systolic function and myocardial perfusion.

Objective:To study the impact of the age-adjusted Charlson comorbidity index (ACCI) on the prognosis of patients with hilar cholangiocarcinoma following laparoscopic surgical resection.Methods:Clinical data of 136 patients with hilar cholangiocarcinoma undergoing laparoscopic surgery at Zhengzhou University People's Hospital between January 2013 and January 2018 were retrospectively analyzed, including 81 males and 55 females, aged (63.6±9.8) years. Patients were divided into two groups based on the median ACCI score of 4.0: the high ACCI group (ACCI>4.0, n=49) and low ACCI group (ACCI≤4.0, n=87). The prognosis was compared between the two group. Univariate and multivariate Cox regression analyses were performed to analyze the effect of ACCI on survival after laparoscopic surgery. Results:The 1- and 3-year cumulative survival rates in low ACCI group were 87.4% and 48.3%, respectively, compared to 53.1% and 4.1% in high ACCI group ( χ2=27.97, P<0.001). Univariate Cox regression analysis indicated that ACCI >4.0 was associated with prognosis ( HR=3.73, 95% CI: 2.44-5.68, P<0.001). Multivariate Cox regression analysis also indicated that ACCI >4.0 was associated with an increased risk of postoperative mortality in patients with hilar cholangiocarcinoma ( HR=2.69, 95% CI: 1.65-4.37, P<0.001). Conclusion:The ACCI is a significant risk factor for survival of patients with hilar cholangiocarcinoma following laparoscopic surgery, which could facilitate a precise preoperative assessment of patient status and choice of surgical approach.

Objective:To analyze the influencing factors of abnormal 15-minute retention rate of indocyanine green (ICG R15) (≥10%) in patients with hepatocellular carcinoma, and to construct a nomogram model, and to evaluate the prediction efficiency of the nomogram model.Methods:The clinical data of 190 patients with hepatocellular carcinoma in Zhengzhou University People's Hospital from December 2017 to June 2022 were retrospectively analyzed, including 148 males and 42 females, aged (57.8±9.9) years. According to ICG R15, the patients were divided into ICG R15 normal group ( n=134, ICG R15<10%) and ICG R15 abnormal group ( n=56, ICG R15≥10%). Univariate and multivariate logistic regression were used to analyze the influencing factors of abnormal ICG R15, and the nomogram model was established. The predictive ability of the model was evaluated by receiver operating characteristic (ROC) curve and C-index, and the model was verified by calibration curve and decision analysis curve. Results:Abnormal ICG R15 group the proportion of liver cirrhosis, albumin ≤35 g/L, hemoglobin ≤110 g/L, platelet count ≤100×10 9/L, prothrombin time >13 s, alanine aminotransferase >40 U/L, aspartate aminotransferase >40 U/L, total bilirubin >34.2 μmol/L, and the largest tumor diameter >5.0 cm, spleen volume >383.1 cm 3, spleen volume to of non-tumor liver volume (SNLR) >0.276 and liver tumor volume >117.2 cm 3 were higher than that of ICG R15 normal group, and the differences were statistically significant (all P<0.05). Logistic regression analysis showed that liver cirrhosis ( OR=3.89, 95% CI: 1.28-11.80, P=0.016), spleen volume >383.1 cm 3( OR=5.17, 95% CI: 1.38-19.38, P=0.015), SNLR >0.276 ( OR=5.54, 95% CI: 1.44-21.26, P=0.013) and total bilirubin >34.2 μmol/L( OR=10.20, 95% CI: 1.88-55.39, P=0.007) increased the risk of abnormal ICG R15. A nomogram model was constructed based on the above risk factors. The C-index of the model was 0.915 (95% CI: 0.872-0.957), and the area under the ROC curve predicted by the nomogram model was 0.915 (95% CI: 0.871-0.958). The calibration curve showed that the correlation index of the abnormal ICG R15 predicted by the nomogram was similar to actual situation. Decision analysis curve showed high returns. Conclusion:Liver cirrhosis, spleen volume >383.1 cm 3, SNLR>0.276 and total bilirubin >34.2 μmol/L were indepentlent risk factors for abnormal ICG R15 in patients with hepatocellur carcinoma. The clinical prediction model of ICG R15 abnormality constructed by nomogram has good prediction efficiency, which can provide a reference for evaluating preoperative liver reserve function of patients with hepatocellular carcinoma.

Objective:To analyze the clinical characteristics of patients with spontaneous low intracranial pressure (SIH).Methods:The study is a retrospective series. The clinical data of patients with SIH who visited Beijing Hospital from May 2017 to March 2022, including gender, age, symptoms, signs, imaging findings, treatment and outcome, were collected and their clinical characteristics were analyzed.Results:Finally, 8 patients with SIH, 6 females and 2 males, aged (33.5±7.3) years, were included. There were 6 cases of acute onset, 1 case of subacute onset, and 1 case of chronic onset. Four cases had pre-onset triggers, 3 cases were exertional and 1 case was exercise. All 8 cases had orthostatic headache. Three cases were accompanied by neck pain. Six cases were accompanied by autonomic dysfunction, 1 case with blurred vision and neck resistance, and 1 case with tinnitus in both ears. There were no obvious abnormalities in blood routine, liver and kidney function, electrolytes, and coagulation function in 8 cases. The results of the lumbar puncture showed that the cerebrospinal fluid pressure was≤60 mmH 2O(1 mmH 2O=0.009 8 kPa) in 7 cases, and 2 cases were so low that they were undetectable. One patient had normal cerebrospinal fluid pressure (90 mmH 2O). The routine results of cerebrospinal fluid showed 4 cases of an increased number of red blood cells and 2 cases of leukocytosis. The biochemical results of cerebrospinal fluid in all 8 cases were normal. All 8 patients underwent non-contrast MRI scan of the head, and 6 cases found abnormalities, including 2 cases of subdural hematoma, 1 case of subarachnoid hemorrhage, 1 case of brain tissue sinking, and 3 cases of intracranial venous sinus dilation (including 1 case with subdural hematoma). All 8 patients underwent MRI enhancement scan of the head, and 5 patients showed diffuse dural enhancement. Three patients underwent digital subtraction angiography myelogram and computed tomography myelogram, and 2 cases found dural cerebrospinal fluid leakage. One patient underwent magnetic resonance water imaging and no cerebrospinal fluid leakage was found. Eight patients were followed up for 38.5 (10.3, 63.0) months, after conservative treatment, 6 cases of headache relief or disappearance, 1 case relapsed and was admitted 1 week after discharge, non-targeted epidural blood patching (EBP) did not relapse, 1 case underwent non-targeted EBP after conservative treatment failure, headache relief, recurrence after 2 months, thoracic spine 3-4 space targeted EBP, headache disappeared, did not recur. Conclusions:The present study indicate that SIH prevalence in young age is common, the main symptom is orthostatic headache, accommodated with multiple clinical symptoms with various imaging abnormalities. Most patients with SIH can be treated conservatively, if the effect is not good, non-targeted or targeted EBP is feasible.

Objective:To analyze the changes in serum IL-1β, IFN-γ and IL-4 levels in children with sepsis and analyze their values in the differential diagnosis of Gram-positive (G + )/Gram-negative (G -) bacterial infection. Methods:Clinical data of 195 children with sepsis admitted to Xuzhou Central Hospital from February 2020 to February 2023 were retrospectively analyzed. They were all confirmed to have G + /G - bacterial infection based on pathogen culturing and identification and enrolled as disease group. Another 180 healthy children taking physical examination in the same hospital during the same period were recruited as control group. The distribution of G + /G - bacterial infection in the disease group was analyzed after pathogen culturing. ELISA was used to detect serum IL-1β, IFN-γ and IL-4 levels in both groups. Differences in the levels of serum IL-1β, IFN-γ and IL-4 were compared between the disease group and the control group as well as between the patients with G + /G - bacterial infection. Receiver operating characteristic (ROC) curve was drawn to evaluate the values of serum IL-1β, IFN-γ and IL-4 levels used alone or in combination in the differential diagnosis of G + /G - bacterial infection. Results:A total of 211 strains were isolated from 195 blood culture samples in the disease group, including 181 strains (85.78%) of G + bacteria and 30 strains (14.22%) of G - bacteria. Coagulase-negative Staphylococcus and Salmonella were the predominant bacteria causing G + /G - bacterial infection, respectively. The levels of serum IL-1β and IFN-γ in the disease group were higher than those in the control group ( P<0.05), while the levels of serum IL-4 were similar in the two groups ( P>0.05). The levels of serum IL-1β, IFN-γ and IL-4 in the patients with G - bacterial infection were higher than those in the patients with G + bacterial infection ( P<0.05). The sensitivity and the area under the ROC curve of serum IL-1β, IFN-γ and IL-4 levels used in combination in the differential diagnosis of G + /G - bacterial infection were respectively 91.62% and 0.960, which were higher than those of each parameter used alone ( P<0.01, P<0.05). However, there was no significant difference in the specificity ( P>0.05). Conclusions:The levels of serum IL-1β and IFN-γ increased in children with sepsis, while the serum IL-4 level was basically normal in them. Children with G - bacterial infection tended to have higher serum IL-1β, IFN-γ and IL-4 levels. The combination use of all three parameters showed higher value in the differential diagnosis of G + /G - bacterial infection.

Résumé
Studies of human and mammalian have revealed that environmental exposure can affect paternal health conditions as well as those of the offspring. However, studies that explore the mechanisms that meditate this transmission are rare. Recently, small noncoding RNAs (sncRNAs) in sperm have seemed crucial to this transmission due to their alteration in sperm in response to environmental exposure, and the methodology of microinjection of isolated total RNA or sncRNAs or synthetically identified sncRNAs gradually lifted the veil of sncRNA regulation during intergenerational inheritance along the male line. Hence, by reviewing relevant literature, this study intends to answer the following research concepts: (1) paternal environmental factors that can be passed on to offspring and are attributed to spermatozoal sncRNAs, (2) potential role of paternal spermatozoal sncRNAs during the intergenerational inheritance process, and (3) the potential mechanism by which spermatozoal sncRNAs meditate intergenerational inheritance. In summary, increased attention highlights the hidden wonder of spermatozoal sncRNAs during intergenerational inheritance. Therefore, in the future, more studies should focus on the origin of RNA alteration, the target of RNA regulation, and how sncRNA regulation during embryonic development can be sustained even in adult offspring.

Hepatocellular carcinoma (HCC), which makes up the majority of liver cancer, is induced by the infection of hepatitis B/C virus. Biomarkers are needed to facilitate the early detection of HCC, which is often diagnosed too late for effective therapy. The tRNA-derived small RNAs (tsRNAs) play vital roles in tumorigenesis and are stable in circulation. However, the diagnostic values and biological functions of circulating tsRNAs, especially for HCC, are still unknown. In this study, we first utilized RNA sequencing followed by quantitative reverse-transcription PCR to analyze tsRNA signatures in HCC serum. We identified tRF-Gln-TTG-006, which was remarkably upregulated in HCC serum (training cohort: 24 HCC patients vs. 24 healthy controls). In the validation stage, we found that tRF-Gln-TTG-006 signature could distinguish HCC cases from healthy subjects with high sensitivity (80.4%) and specificity (79.4%) even in the early stage (Stage I: sensitivity, 79.0%; specificity, 74.8%; 155 healthy controls vs. 153 HCC patients from two cohorts). Moreover, in vitro studies indicated that circulating tRF-Gln-TTG-006 was released from tumor cells, and its biological function was predicted by bioinformatics assay and validated by colony formation and apoptosis assays. In summary, our study demonstrated that serum tsRNA signature may serve as a novel biomarker of HCC.

BACKGROUND@#Primary lung squamous carcinoma that produces alpha-fetoprotein (AFP) is rare and only four related cases have been reported so far. The specific reasons for elevated serum level of AFP and effective treatment regimens for AFP-producing lung squamous carcinoma are not clear. This paper reports the diagnosis and treatment of AFP-producing lung squamous carcinoma so as to provide some references for similar cases in clinical practice.@*METHODS@#The diagnosis and treatment of an AFP-producing lung squamous carcinoma patient admitted to the Shandong Cancer Hospital on October 23, 2020 was retrospectively analyzed, and literatures were reviewed.@*RESULTS@#A 52-year-old male patient was diagnosed as T4N3M0 stage, IIIc right upper lobe lung squamous cell carcinoma with mediastinal lymph node metastasis and multiple metastases in the lung. The main tumor marker was abnormally increased serum AFP. After the rapid progression of two lines chemotherapy, the patient was given anlotinib combined with carrizumab as third-line treatment. The efficacy evaluation reached to partial response (PR) and stable disease (SD) after 2 and 4 cycles of treatment, respectively. The treatment regimen was replaced with albumin paclitaxel plus carrizumab due to gastrointestinal bleeding after the fifth cycle. The patient's condition was under continuous control.@*CONCLUSIONS@#The AFP-producing lung squamous carcinoma patient had a good response to anlotinib and immunotherapy in the case report, which may provide some guidances for the clinical practice and the research on AFP-producing lung squamous carcinoma.

Objective:To investigate the clinical application of noninvasive high frequency oscillatory ventilation(nHFOV)and heated humidified high flow nasal cannula(HHHFNC)in sequential ventilator evacuation of preterm infants with very low birth weight with respiratory distress syndrome(RDS).Methods:A total of 88 preterm infants of very low birth weight with RDS were enrolled in the study, who had received endotracheal intubation invasive ventilation and were ready to be replaced by non-invasive ventilation at neonatal intensive care unit(NICU)of Xuzhou Central Hospital from May 2017 to January 2020.All premature infants were routinely treated with caffeine citrate.They were divided into two groups through random number table: nHFOV/HHHFNC group(45 cases)and continuous positive airway pressure(nCPAP)/oxygen hood group(43 cases). nHFOV was given after invasive ventilator removal and HHHFNC transition was followed after nHFOV withdrawal in the nHFOV/HHHFNC group, while nCPAP was given after invasive ventilator removal and oxygen hood was followed after nCPAP withdrawal in the nCPAP/oxygen hood group.The main observation consequences were compared with arterial blood gas indexes after invasive ventilator evacuation, weaning effect and the incidence of related complications.Results:(1)There were no statistically differences between the two groups in terms of gender, gestational age, birth weight, Apgar score at 1 min and 5 min after birth, the number of glucocorticoid usage in 24 h before delivery, the number of pulmonary surfactant usage, invasive ventilation time and RDS grading( P>0.05). (2)The PaO 2, PaCO 2and oxygenation index(OI=100×MAP×FiO 2/PaO 2)of the nHFOV/HHHFNC group at 1 h and 24 h after invasive ventilator removal showed significant difference compared with the nCPAP/oxygen hood group( P<0.05). The differences as the following listed were statistically significant( P<0.05)between the two groups, including the failure rate of invasive ventilation weaning during 72 h [9%(4/45)vs.26%(11/43)], the incidence of frequent apnea [7%(3/45)vs.23%(10/43)], the failure rate of nHFOV and nCPAP noninvasive ventilation weaning [4%(2/45)vs.21%(9/43)], the oxygen-used time [12.02(9.08~12.31)d vs.14.44(11.32~13.26)d] and the incidence of nasal injury [4%(2/45)vs.26%(11/43)]. (3)The time of the first noninvasive ventilation of nHFOV and nCPAP, the incidences of lung air leakage, neonatal necrotizing enterocolitis, grade Ⅲ to Ⅳ intraventricular hemorrhage, above stageⅡretinopathy, bronchopulmonary dysplasia and the mortality rate between the two groups showed no statistical significance( P>0.05). Conclusion:nHFOV and HHHFNC used in the sequential ventilator evacuation of RDS in preterm infants with very low birth weight could improve oxygenation, reduce CO 2retention, improve the success rate of machine weaning and reduce the occurrence of apnea and nasal injury.

Five patients with myopathy associated with anti-signal recognition peptide antibodies, admitted to our hospital from December 2015 to June 2018, were chosen in our study, and their clinical and pathological manifestations and treatments were retrospectively analyzed. Five patients showed subacute or chronic onset and proximal limb muscle weakness. Serum creatine kinase level was significantly elevated. Immunoblotting assay confirmed the positive anti-signal recognition particle antibody. EMG prompted myogenic damage. Pathological features included muscle degeneration, necrosis with regeneration, visible atrophy and hypertrophic of muscle fiber, connective tissue hyperplasia and a small amount of inflammatory cell infiltration. Immunohistochemical staining showed necrotizing muscle fiber infiltrated with CD4-positive and CD8-positive lymphocytes and CD68-positive macrophages, and no CD20-positive lymphocytes and CD303-positive dendritic cells were observed. Two patients had expressed a bit of c5b-9 positive capillary. Anti-sarcoglycans staining, anti-dysferlin staining and dystrophin staining showed continuous strong positive expression. Follow-up study found that all patients were response to glucocorticoid, and a combination therapy of immunoglobulin and immunosuppression were necessary for some patients.

Objective@#To explore the relationship between coronary tortuosity and coronary microvascular disease (CMVD).@*Methods@#Patients with typical angina symptoms and without serious coronary artery stenosis by coronary angiography were enrolled from June 2014 to December 2016, and CMVD was diagnosed by single photon emission tomography (SPECT). According to the SPECT results, patients were divided to the CMVD group and non-CMVD group. The baseline clinical characteristics, results of coronary angiography were compared between the two groups. The logistic analysis was used to analyze the relationship between coronary tortuosity and CMVD.@*Result@#A total of 117 cases were enrolled, with 69 cases in the CMVD group and 48 cases in the non-CMVD group. No differences were found in gender distribution, age, hypertension, lipid abnormality, hyperuricemia and uses of statins between the two groups (all P>0.05). Incidence of diabetes (78.26%(54/69) vs. 35.42% (17/48) , P<0.05), hs-CRP ((4.29±2.15)mmol/L vs. (2.63±1.20)mmol/L, P<0.001), LDL-C ((2.98±0.96)mmol/L vs. (2.52±0.83)mmol/L, P=0.008) and homocysteine ((13.7±5.61)mmol/L vs. (11.5±4.38)mmol/L, P=0.025) levels were higher in the CMVD group than in the non-CMVD group. The data derived from echocardiographic examination were similar between the two groups. The Corrected TIMI frame counts were higher in the CMVD group than in non-CMVD group (LAD: 31.56±4.92 vs. 27.31±3.75, LCX: 29.47±4.18 vs. 26.62±3.19, RCA: 29.09±5.05 vs. 26.24±3.28, all P<0.001). The incidences of coronary atherosclerosis (76.81% (53/69) vs. 27.08% (13/48) , P<0.001) and coronary tortuosity ( (60.87% (42/69) vs. 33.33% (16/48) , P=0.035) were also higher in the CMVD group than in non-CMVD group. Logistic analysis found that coronary tortuosity (OR=6.111, 95%CI 2.707-13.794, P<0.001), diabetes (OR=6.565, 95%CI 2.883-14.948, P<0.001) and coronary atherosclerosis (OR=8.918, 95%CI 3.822-20.808, P<0.001) were independent risk factors of CMVD.@*Conclusion@#Coronary tortuosity, diabetes and coronary atherosclerosis are related to CMVD in this patient cohort.
Résumé
Objective To investigate the unmet needs of thyroid cancer patients undergoing 131Itreatment and their relationship with psychological distress and quality of life.Methods From October 2014 to March 2016,a total of 338 patients (106 males,232 females,average age (35.50±9.98) years) with thyroid cancer who were receiving 131I treatment were enrolled.The 34 items of Supportive Care Needs Survey Short Form (SNCS-SF34) were used to investigate the unmet care needs of patients.Patients' perceptions of distress and main causes of distress were measured by Distress Thermometers (DT) and issue list.The 12-item Short-Form Health Survey (SF-12) was used to measure patients' quality of life.Pearson correlation analysis was used to analyze the data.Results The degrees of patients' unmet care needs from high to low were as following:health information needs (65.38％,221/338),psychological needs (47.93％,162/338),patients' care and support needs (44.08％,149/338),physical and daily needs (36.09％,122/338) and sexual needs (34.32％,116/338).There were 47.93％(162/388) patients with DT score ＞ 4.The top three causes of patients' distress were fears,fatigue and memory deterioration.Degree of unmet needs for patients had positive correlation with the degree of psychological distress (r values:0.232-0.462,all P＜0.01).The unmet physiological and daily needs and psychological needs of patients had negative correlations with several dimensions of quality of life (r values:from-0.367 to-0.202,all P＜ 0.05).Conclusions The unmet care needs of patients with thyroid cancer have correlations with their psychological distress and quality of life.Evaluation of the unmet care needs of patients with thyroid cancer could be beneficial for providing the targeted care.
Résumé
Objective To explore the experience of thyroid cancer patients about the diagnosis and post-surgical radioactive iodine treatment. Methods A qualitative, descriptive study was used. Thirty-eight patients with thyroid cancer who were undergoing post-surgical radioactive iodine treatment participated in this study. Dairies about the participants′ experience were collected from them. Interpretative phenomenological analysis was used. Results Three superordinate themes emerged: the psychological process from distress to acceptance; the experience about post-surgical radioactive iodine treatment; and personal growth related to the cancer. Conclusions Understanding the psychological process of patients with thyroid cancer after the diagnosis and their experience about post-surgical radioactive iodine treatment can contribute to the clinical staff to improve the care quality for this group.
Résumé
Objective: To explore the impact of ticagrelor on myocardial microcirculation in patients of non-ST elevation myocardial infarction (NSTEMI) after percutaneous coronary intervention (PCI). Methods: A total of 80 NSTEMI patients treated in our hospital from 2015-03 to 2015-12 were enrolled. All patients received coronary angiography (CAG) and PCI, they were randomly divided into 2 groups: ticagrelor (TA) group and clopidogrel (CA) group, n=40 in each group. The baseline condition, PCI related parameters, plasma levels of SOD, MDA at pre- and 24h, 72h post-PCI were compared, the incidence of major adverse cardiac events (MACE) within 30 days after PCI was also compared between 2 groups. Results: The baseline condition, proportion of infarction-related vessels, average length and diameter of implanted stents were similar between 2 groups, all P>0.05. Compared with CA group, TA group had the less post-operative CTFC in LAD and RCA, P0.05. The ratios of acute pre-operative, post-operative TIMI grade 3 and slow flow incidence were similar between 2 groups, P>0.05. The peak values of CK-MB and cTnI in TA group were lower than CA group, P<0.05. Compared with baseline condition, MDA levels at 24h and 72h post-operation were increased in both groups, all P<0.001; compared with CA group, TA group had the lower MDA level at 24h post-operation, P=0.023, MAD was further reduced at 72h post-operation in TA group, P=0.043. Compared with baseline condition, SOD levels at 24h and 72h post-operation were decreased in both groups, all P<0.001; compared with CA group, TA group had the higher SOD level at 24h post-operation, P=0.013, SOD was elevated at 72h post-operation in both groups, the elevation was more obvious in TA group, P=0.049. The incidence of MACE was similar between 2 groups within 30 days of PCI,. Conclusion: Ticagrelor could improve myocardial microcirculation in NSTEMI patients after PCI; it was safe and without obvious adverse effects.
Résumé
Objective To explore the decision-making process of medical students who turned the major from the medicine to other majors,and the related factors that hindered them continuing to study the medicine.Methods According to the design of interpretative phenomenon logical analysis,semi-structured in-depth interviews were used to collect the data.Participants were six undergraduate students who had moved from medical major to another major.Interviews were recorded on audio-tape with the students' permission and then transcribed verbatim.The transcribed interviews were analyzed according to six steps of interpretative phenomenological analysis.Results Even if the participants had left the medical major,they still expressed a strong sense of professional identity for the doctor.However,they also admitted that the professional process of medicine students was very hard and tired,and couldn't get the equal return for their payment.They thus were lack of confidence for the future.Some of the participants talked about the fact that they had been curious about the future of medical students.Internet and seniors were the main avenues for obtaining job-related information,but they were often plagued by the negative information.Education about career adaptation should be carried out as soon as possible,to strengthen the professional identity of medical students,and enhance their ability to defend against negative information,which could help to deal with the status of high turnover rate for medical students.Conclusion Based on the students' perspective,exploring the decision-making process of turning major for medical students will contribute to the educators taking effective strategies to improve the students' career identity,stabilize their professional thought,and reduce the loss of the medical students.
