[Efficacy and safety analysis of P-GemDOx regimen and stratified prognosis in patients with early extranodal NK/T cell lymphoma].

Objective: To assess the efficacy, safety, and related prognostic factors associated with the P-GemDOx regimen as a first-line treatment for patients with early-stage extranodal natural killer (NK) /T cell lymphoma (ENKTL) . Methods: A retrospective analysis was performed on sixty early-stage ENKTL patients treated with the P-GemDOx regimen who were admitted to the First Affiliated Hospital of Nanjing Medical University between August 2015 and May 2021. The Chi-square test or Fisher's exact test was used to compare group differences, and the Log-rank test was used to compare the differences in survival. Survival outcomes and prognostic factors were examined. Results: After completing 4 to 6 cycles of P-GemDOx chemotherapy, the overall response rate (ORR) was 88.3%, with forty-six patients (76.7% ) achieving complete response (CR). The 4-year progression-free survival (PFS) and overall survival (OS) rates were (66.3±7.1) % and (79.5±6.0) %, respectively. According to the PINK/PINK-E model, there was no significant difference in survival outcomes among risk groups. 23.3% of patients experienced progression of disease within 24 months (POD<24). OS estimates differed significantly (P<0.001) between the POD<24 group (n=14) and the POD≥24 group (n=46). Analysis showed that SUVmax > 12.8 at diagnosis, non-single nasal cavity infiltration, and response less than CR after 4-6 cycles all had a significant association with POD24. We used these data as the basis for predicting POD<24 international prognostic index (POD24-IPI). Patients were stratified into low-risk (no risk factors), intermediate-risk (one risk factor), or high risk (two or three risk factors). These groups were associated with 4-year OS rate of 100%, (85.6±9.7) %, and (65.0±10.2) %, respectively (P=0.014). The P-GemDOx regimen was well tolerated, with hematological toxicity being the main side effect. Conclusion: This study demonstrated that the P-GemDOx regimen is effective and safe in the first-line treatment of early-stage ENKTL, and POD24-IPI is a promising prognostic model.

Quantitative image features of gadoxetic acid-enhanced MRI for predicting glypican-3 expression of small hepatocellular carcinoma ≤3 cm.

AIM: To explore the value of quantitative image features of gadoxetic acid-enhanced magnetic resonance imaging (MRI) for predicting Gglypican-3 (GPC3) expression of single hepatocellular carcinoma (HCC) ≤3 cm. MATERIALS AND METHODS: One hundred and forty-nine patients with histopathologically confirmed HCC were included retrospectively. Quantitative image features and clinicopathological parameters were analysed. The significant predictors for GPC3 expression were identified using multivariate logistic regression analyses. Nomograms were constructed from the prediction model and the progression-free survival (PFS) rate was evaluated by the Kaplan-Meier method. RESULTS: The tumour-to-liver signal intensity (SI) ratio on the hepatobiliary phase (HBP; odds ratio [OR] = 0.004; p=0.001), serum alpha-fetoprotein (AFP) > 20 ng/ml (OR=6.175; p<0.001), and non-smooth tumour margin (OR=4.866; p=0.002) were independent significant factors for GPC3 expression. When the three factors were combined, the diagnostic specificity was 97.7% (42/43). The nomogram based on the predictive model performed satisfactorily (C-index: 0.852). Kaplan-Meier curves showed that patients with GPC3-positive HCCs have lower PFS rates than patients with GPC3-negative HCCs (Log-rank test, p=0.006). CONCLUSION: The tumour-to-liver SI ratio on the HBP combined with serum AFP >20 ng/ml and non-smooth tumour margin are potential predictive factors for GPC3 expression of small HCC ≤3cm. GPC3 expression is correlated with a poor prognosis in HCC patients.

[The value of a nomogram based on clinical data and contrast enhanced CT radiomics in the preoperative prediction of Epstein-Barr virus-associated gastric carcinoma].

Objective: To explore the value of a nomogram based on clinical data and enhanced CT radiomics in the prediction of Epstein-Barr virus-associated gastric carcinoma(EBVaGC). Methods: The data of 136 patients, including 100 males and 36 females, aged [M (Q1, Q3)] 65 (53, 71) years, with gastric cancer confirmed by surgery and pathology were retrospectively analyzed. According to Epstein-Barr virus-encoded small RNA (EBER) in situ hybridization, those patients were divided into Epstein-Barr virus (EBV) positive group (n=32) and EBV negative group (n=104). All patients underwent multi-phase enhanced CT scanning before surgery and randomly assigned to the training group (n=95) and validation group (n=41) in a ratio of 7︰3. MaZda software was used to extract radiomics features of enhanced CT images. The intra-group correlation coefficient (ICC), variance analysis and minimum absolute shrinkage and selection algorithm (LASSO) regression were used to reduce the dimensionality of the radiomics features, and then the radiomics score (Radscore) was calculated. The nomogram model was based on combined clinical data, morphological features and Radscore. The predictive power of the nomogram was evaluated according to the area under the receiver operating characteristic curve (AUC), and the net clinical benefit of the nomogram was evaluated by the decision curve and calibration curves were drawn according to the data of the training group and the validation group to analyze the consistency of the nomogram model. Results: After selection, six optimal radiomics features were obtained, including Mean, Skewness, S(1, 0) Sum entropy, S(1, 1) Contrast, 99% percentile and S(2, 2)Angular second moment. Radscore of EBV positive group were higher than that of the EBV negative group (training group: 3.78±0.83 vs 2.80±0.98; validation group: 3.81±0.47 vs 2.94±0.95) (both P<0.05) both in the training group and validation group. The AUC of the radiomics model in training group and validation group were 0.773(95%CI:0.612-0.962)and 0.792(95%CI:0.597-0.927)respectively,and the sensitivity and specificity were 63.6% and 93.1%, 70.0% and 87.1%, respectively. The AUC of the nomogram model based on clinical data and radiomics in the training group and the validation group were 0.883(95%CI:0.644-0.984) and 0.851(95%CI:0.715-0.996), respectively. The nomogram model showed superior predictive performance (both P<0.05). Conclusion: The nomogram model based on clinical data and radiomics has better efficacy in the prediction of Epstein-Barr virus associated gastric cancer.

Objective: To investigate the efficacy and safety of a new cervical artificial disc prosthesis in the treatment of cervical degenerative diseases. Methods: The clinical data of 18 patients with single-level cervical degenerative diseases who underwent three dimensional printed anatomical bionic cervical disc replacement at Department of Spinal Surgery,Honghui Hospital,Xi'an Jiaotong University from May 2019 to July 2020 were analyzed retrospectively. There were 7 males and 11 females,aged (45±8) years old(range:28 to 58 years).The surgical segment was located at C3－4 level in 2 cases, C4－5 level in 5 cases, C5－6 level in 9 cases, and C6－7 level in 2 cases.The clinical and radiographic outcomes were recorded and compared at preoperative,postoperative times of one month and twelve months.The clinical assessments contained Japanese orthopedic association (JOA) score,neck disability index (NDI) and visual analogue scale (VAS).Imaging assessments included range of motion (ROM) of cervical spine, prosthesis subsidence and prosthesis anteroposterior migration.Repeated measurement variance analysis was used for comparison between groups,and paired t test was used for pairwise comparison. Results: All patients underwent the operation successfully and were followed up for more than 12 months.Compared with preoperative score,the JOA score,NDI and VAS were significantly improved after surgery (all P<0.01).There was no significant difference in postoperative ROM compared with 1-and 12-month preoperative ROM (t=1.570,P=0.135;t=1.744,P=0.099). The prosthesis subsidence was (0.29±0.13) mm (range: 0.18 to 0.50 mm) at 12-month postoperatively.The migration of prosthesis at 12-months postoperatively were (0.71±0.20) mm (range: 0.44 to 1.08 mm).There was no prosthesis subsidence or migration>2 mm at 12-month postoperatively. Conclusion: Three dimensional printed anatomical biomimetic cervical artificial disc replacement has a good early clinical effect in the treatment of cervical degenerative diseases, good mobility can be obtained while maintaining stability.

[Imaging phenotypes of chronic obstructive pulmonary disease based on biphasic quantitative CT features].

Quantitative analysis was performed on the biphasic CT of 40 patients [43-80 (66.1±9.0) years old, including 37 males] with stable chronic obstructive pulmonary disease (COPD) to measure the percentage of emphysema (Emph%); the percentage of small airway disease (SAD%) and the square root of the wall area of hypothetical airway with internal perimeter of 10 mm (Pi10). Based on the cluster analysis of Emph%, SAD% and Pi10, the patients were divided into five imaging phenotypes including no obvious imaging abnormality type (n=11), small airway disease-dominant type (n=9), bronchial wall thickening-dominant type (n=8), emphysema-dominant type (n=6) and mixed type (n=6). Patients with the same Global Initiative for Chronic Obstructive Lung Disease (GOLD) grade had similar degree of airflow limitation, but the lesion components were not identical. Being different from the traditional imaging classification, even in the cases of mild emphysema, they can be further divided into small airway disease-dominant type and bronchial wall thickening-dominant type according to the difference of airway disease.

Near-GeV Electron Beams at a Few Per-Mille Level from a Laser Wakefield Accelerator via Density-Tailored Plasma.

A simple, efficient scheme was developed to obtain near-gigaelectronvolt electron beams with energy spreads of few per-mille level in a single-stage laser wakefield accelerator. Longitudinal plasma density was tailored to control relativistic laser-beam evolution, resulting in injection, dechirping, and a quasi-phase-stable acceleration. With this scheme, electron beams with peak energies of 780-840 MeV, rms energy spreads of 2.4‰-4.1‰, charges of 8.5-23.6 pC, and rms divergences of 0.1-0.4 mrad were experimentally obtained. Quasi-three-dimensional particle-in-cell simulations agreed well with the experimental results. The dechirping strength was estimated to reach up to 11 TeV/mm/m, which is higher than previously obtained results. Such high-quality electron beams will boost the development of compact intense coherent radiation sources and x-ray free-electron lasers.

Objective: To apply artificial intelligence technology in clinical real-world data of patients with primary hepatocellular carcinoma, explore the precise treatment of disease and build up artificial intelligence-based clinical decision support system. Methods: A total of 5 642 patients with primary hepatocellular carcinoma admitted to West China Hospital from July 2004 to June 2016 with complete follow-up records were included in the study. A merged model composed of multiple sub-classifiers was adopted to calculate therapy recommendation coefficient, and receiver operator characteristic curve was analyzed. Survival risk and recurrence risk were predicted by DeepSurv algorithm, and Kaplan-Meier survival curves were further compared among low, middle and high risk groups. Siamese-Net was applied to find similar patients. Results: The Top-1 and Top-2 accuracy of therapy recommendation coefficient reached 82.36% and 94.13% respectively. In internal verification of West China Hospital, the above-mentioned value reached 95.10% in accordance with multi-disciplinary team results. The C-index derived from survival risk model was 0.735 (95%CI:0.70-0.77), and the difference of Kaplan-Meier in pairwise comparison was of statistical significance under log-rank test (P<0.001). Meanwhile, the C-index derived from recurrence risk model was 0.705 (95%CI:0.68-0.73), and the difference of Kaplan-Meier in pairwise comparison was of statistical significance under log-rank test (P<0.001). Conclusions: The artificial intelligence-based clinical decision support system for primary hepatocellular carcinoma has can accurately make therapy recommendation and prognosis prediction for primary hepatocellular carcinoma.

Health-Related Quality of Life Comparisons After Radical Therapy for Early-Stage Hepatocellular Carcinoma.

BACKGROUND: For cancer patients, health-related quality of life (HRQoL) is as important as other key outcomes, such as overall survival and tumor-free survival. Liver transplantation (LT), resection, and radiofrequency ablation (RFA) are 3 radical therapies for hepatocellular carcinoma (HCC) that result in similar survival. The main objective of this study was to assess and compare long-term HRQoL scores for patients with early-stage (tumor diameter ≤3 cm) HCC after LT, resection, or RFA. METHODS: A total of 128 HCC patients with a single tumor ≤3 cm and who agreed to undergo LT, resection, or RFA were included in the present analysis. Postoperative HRQoL was evaluated by using the Medical Outcomes Study 36-Item Short Form Health Survey questionnaire. The 3 groups were compared at the 6-month and 3-year time points. RESULTS: The 3 groups showed comparable 3-year HCC recurrence rates (P > .05). Compared with the LT and resection groups, the RFA group had significantly higher scores for bodily pain, general health, and vitality 6 months after surgery (all P values < .05). Moreover, at 3 years after surgery, the RFA group had higher scores for bodily pain and vitality than the other 2 groups (P < .05) and a higher general health score than the resection group. Other aspects of HRQoL were comparable among the 3 groups at both time points. CONCLUSIONS: Due to its comparable HCC recurrence rate and superior long-term HRQoL scores relative to other radical therapies, RFA may be the first-choice treatment for solitary early-stage HCC.

[Estimating and projecting the acute effect of cold spells on excess mortality under climate change in Guangzhou].

Objective: To estimate future excess mortality attributable to cold spells in Guangzhou, China. Methods: We collected the mortality data and metrological data from 2009-2013 of Guangzhou to calculated the association between cold spell days and non-accidental mortality with GLM model. Then we projected future daily average temperatures (2020-2039 (2020s) , 2050-2069 (2050s) , 2080-2099 (2080s) ) with 5 GCMs models and 2 RCPs (RCP4.5 and RCP8.5) to identify cold spell days. The baseline period was the 1980s (1980-1999). Finally, calculated the yearly cold spells related excess death of 1980s, 2020s, 2050s, and 2080s with average daily death count of non-cold spell days, exposure-response relationship, and yearly number of cold spell days. Results: The average of daily non-accidental mortality in Guangzhou from 2009 to 2013 was 96, and the average of daily average was 22.0 ℃. Cold spell days were associated with 3.3% (95%CI: 0.4%-6.2%) increase in non-accidental mortality. In 1980s, yearly cold spells related deaths were 34 (95%CI: 4-64). In 2020s, the number will increase by 0-10; in 2050s, the number will increase by 1-9; and in 2080s, will increase by 1-9 under the RCP4.5 scenario. In 2020s, the number will increase by 0-9; in 2050s, the number will increase by 1-6; and in 2080s, will increase by 0-11 under the RCP8.5 scenario. Conclusion: The cold spells related non-accidental deaths in Guangzhou will increase in future under climate change.

[Simulation study of air quality health index in 5 cities in China: 2013-2015].

Objective: To construct the air quality health index (AQHI) by inclusion of air pollutants PM(2.5) and O(3) in Guangzhou, Shanghai, Xi' an, Beijing, Shenyang, and explore scientificity and feasibility of its application in China. Methods: The daily average concentrations of PM(2.5) and O(3) in air, and daily average mortality from 2013 to 2015 in the 5 cities in China, the exposure-response coefficients of PM(2.5) and O(3) and total mortality from Meta studies in China were used to construct local AQHI. The health risk levels of air pollution in the 5 cities were calculated and compared with the characteristics of single pollutant concentrationof PM(2.5) or O(3). Results: In the 5 cities, the average concentration of PM(2.5) was highest in Beijing (82 µg/m(3)) and lowest in Guangzhou (46 µg/m(3)). And the average concentration of O(3) was highest in Shanghai (72 µg/m(3)) and lowest in Xi' an (45 µg/m(3)). In all the cities, the average concentration of PM(2.5) was highest in winter and lowest in summer. In summer, the average concentration of O(3) was lowest. But the health risk level of AQHI showed that the 5 cities had higher frequency of low or medium risk averagely. And Beijing had the highest frequency of high risk in summer (5.69%). Xi' an had the highest frequency of extremely high risk in winter (1.63%). Conclusions: In this study, AQHI could be constructed by using air PM(2.5) and O(3) concentration data which can be obtained in many areas in China. The application of this index is scientific and feasible in China.

[Prevalence of laryngopharyngeal reflux disease in Fuzhou region of China].

Objective: To assess the prevalence of laryngopharyngeal reflux disease (LPRD) in the Fuzhou region. Methods: A total of 4100 subjects who aged from 10 to 70 years derived from a random cluster sampling in fourty districts of Fuzhou region and they were asked to complete questionnaires. According to the grade standard of reflux symptom index (RSI), subjects with total score more than 13 were defined as having LPRD. The factors associated with LPRD were evaluated with corrective analysis. Results: Effective questionnaires were obtained from 4 063 of 4 100 subjects. The prevalence of LPRD was 5.00%(203/4 063). The prevalence of LPRD in subjects of 30-39 years old was significantly higher than that in subjects of 10-19 years old (χ2=8.532, P=0.003). The prevalence of LPRD in men was higher than that in women (P<0.001). There were significant difference in the prevalence of LPRD between different occupations (P<0.001). The prevalence of LPRD in industrial workers was 7.89% (24/304), higher than that in students (4/196, 3.14%). RSI was correlated with clearing throat, with a correlation coefficient of 0.687. LPRD was also correlated with dysphagia and pharyngeal foreign body sensation. Conclusions: The prevalence of LPRD in Fuzhou region is 5.00% and LPRD is closely related to age, sex, occupation, clearing throat, dysphagia and pharyngeal foreign body sensation.

High-Brightness High-Energy Electron Beams from a Laser Wakefield Accelerator via Energy Chirp Control.

By designing a structured gas density profile between the dual-stage gas jets to manipulate electron seeding and energy chirp reversal for compressing the energy spread, we have experimentally produced high-brightness high-energy electron beams from a cascaded laser wakefield accelerator with peak energies in the range of 200-600 MeV, 0.4%-1.2% rms energy spread, 10-80 pC charge, and ∼0.2 mrad rms divergence. The maximum six-dimensional brightness B_{6D,n} is estimated as ∼6.5×10^{15} A/m^{2}/0.1%, which is very close to the typical brightness of e beams from state-of-the-art linac drivers. These high-brightness high-energy e beams may lead to the realization of compact monoenergetic gamma-ray and intense coherent x-ray radiation sources.

Expression of CALR mutants causes mpl-dependent thrombocytosis in zebrafish.

CALR mutations are identified in about 30% of JAK2/MPL-unmutated myeloproliferative neoplasms (MPNs) including essential thrombocythemia (ET) and primary myelofibrosis. Although the molecular pathogenesis of CALR mutations leading to MPNs has been studied using in vitro cell lines models, how mutant CALR may affect developmental hematopoiesis remains unknown. Here we took advantage of the zebrafish model to examine the effects of mutant CALR on early hematopoiesis and model human CALR-mutated MPNs. We identified three zebrafish genes orthologous to human CALR, referred to as calr, calr3a and calr3b. The expression of CALR-del52 and CALR-ins5 mutants caused an increase in the hematopoietic stem/progenitor cells followed by thrombocytosis without affecting normal angiogenesis. The expression of CALR mutants also perturbed early developmental hematopoiesis in zebrafish. Importantly, morpholino knockdown of mpl but not epor or csf3r could significantly attenuate the effects of mutant CALR. Furthermore, the expression of mutant CALR caused jak-stat signaling activation in zebrafish that could be blocked by JAK inhibitors (ruxolitinib and fedratinib). These findings showed that mutant CALR activates jak-stat signaling through an mpl-dependent mechanism to mediate pathogenic thrombopoiesis in zebrafish, and illustrated that the signaling machinery related to mutant CALR tumorigenesis are conserved between human and zebrafish.

Health-Related Quality of Life and Psychological Distress in Patients With Early-Stage Hepatocellular Carcinoma After Hepatic Resection or Transplantation.

BACKGROUND: The aim of our study was to compare the post-operative health-related quality of life in patients with small hepatocellular carcinoma (HCC; within the Milan criteria) after liver resection or liver transplantation. METHODS: From August 2000 to December 2010, 207 patients were diagnosed with early HCC within the Milan criteria. We divided these patients into 2 groups according to their curative schedule: the liver transplantation group (n = 95) and the liver resection group (n = 110). We compared the baseline characteristics of these 2 groups of patients, after which we focused on comparing the post-operative health-related quality of life (HRQOL) and psychological outcome in these 2 groups. RESULTS: The demographics of the patients in the 2 groups were similar, and there were no significant differences except for higher family income in the transplantation group (P = .002).With long-term follow-up, there were no significant differences in the 8 domains of the HRQOL and the 9 domains of the psychological outcome measure between the 2 groups. Both the transplantation and resection groups exhibited good outcomes in both HRQOL and psychological outcome measures. CONCLUSIONS: Several years after operation, early-stage HCC patients who underwent liver transplantation or resection had similar long-term HRQOL and psychological outcomes.

Early enteral and parenteral nutrition on immune functions of neurocritically ill patients.

This study was designed to investigate the influence of early enteral and parenteral nutrition on immune functions of neurocritically ill patients. Patients who were admitted to the neurological intensive care unit (ICU) of The Second Affiliated Hospital of Zhengzhou University between May 2014 and January 2016 were selected. They had been hospitalized for more than one week and received enteral nutrition (EN) via nasogastric tube, with a gross energy of 25 kcal/(Kg • d). Patients were divided into EN group, EN + early PN (EPN) group and EN + supplemental PN (SPN) group according to the time of PN support. Differences in patients’ general information and changes in serum protein and immune indexes were compared between the three groups. On admission, patients’ Glasgow coma scale (GCS), age, immune functions and protein indexes had no obvious differences between the three groups. After nutritional support, serum protein level reduced in the EN group while prealbumin (PALB) and retinol binding protein (RBP) increased in the EN + EPN group and EN + SPN group after one week of admission to hospital, and the differences were statistically significant (p less than 0.05). Total protein (TP), albumin (ALB), PALB and transferrin (TRF) increased significantly in the EN + EPN group and EN + SPN group compared with the EN group (p < 0.05); before and after treatment, an increase was found in ALB in the EN + EPN group in comparison with EN + SPN group, with a notable difference (p < 0.05); C3, C4, immunoglobulin M (IgM) and immunoglobulin A (IgA) increased in the EN + SPN group after nutritional support compared with before treatment, and the difference was statistically significant (p < 0.05). Moreover, immunoglobulin G (IgG) and IgA in the EN + EPN group increased after nutritional support comparing to prior to nutritional support, and the difference was statistically significant (p < 0.05). After nutritional treatment, IgA and IgG increased markedly in the EN + EPN group, and there was a statistical significance between the groups (p < 0.05); the EN + EPN group and EN + SPN group exceeded the EN group in total lymphocyte count (TLC), and the difference had a statistical significance (p less than 0.05). These results demonstrate that neurocritically ill patients achieving the target energy can avoid malnutrition and immunodeficiency; serum protein decrease can cause malnutrition after one week of EN support; and enteral and parenteral nutrition can improve nutritional and immune indicators of neurocritically ill patients in the acute phase. In addition, EPN is more likely to improve malnutrition and immune functions of critical patients than SPN.

[Living donor liver transplantation for the treatment complicated hepatic cystic echinococcosis: first case report from China].

OBJECTIVE: To report the first clinical experience of living donor liver transplantation(LDLT) in patient with complicated hepatic cystic echinococcosis in China. METHODS: First Affiliated Hospital of Xinjiang Medical University successfully implemented LDLT in the treatment of one patient with complicated hepatic cystic echinococcosis after four times liver surgery and secondary congestive cirrhosis on May 9, 2015. The clinical data of the patient has been retrospectively analyzed. RESULTS: LDLT procedure was successfully performed in a patient with four previous liver intervention due to his recurrence. The patient was lack of right lobe, while with significant hypertrophy in left lobe. The reoccurred lesion compressed the retrohepatic vena cava, left hepatic vein, portal vein, that led to the stricture of retrohepatic vena cava, left hepatic vein orifice. The phlebography displayed remarkable stricture in retrohepatic vena cava and rich collateral circulation by which the venous blood flow back to the right atrium via paravertebral vein. The orifice of left hepatic vein shaped as hair-like so that the stenting was impossibly. After the multi-disciplinary team discussion, the liver transplantation was proposed, while the autotransplantation was considered as first line option, and with the backup of living related donor. The laparotomy showed the hugely enlarged liver with nodular changes. The frozen section was tested twice and showed as spotty necrosis with pseudo-lobe formation. Although the enlarged left lobe about 2 000 g weight, the liver colored as grey with cotton-like texture, the plan for autotransplantation was abandoned regarding the high risk for post-operative liver failure. Therefore, LDLT was performed. The donor was her brother who donated right lobe with 685 g weight. The operation time was 1 005 min with anhepatic time 335 min. Total of 12 units red blood cell suspension was transfused. The coagulating function was back to normal in 3 days after operation. The patient was discharged at 30 days after operation, while the routine blood test and biochemical markers had back to normal levels. The patient had taken tacrolimus and methylprednisolone with normal life. The liver functions of transplanted liver were normal in 90 days after surgery. The patient was able to self-activity and regular outpatient follow-up. CONCLUSION: Hepatic CE is an infectious disease, and liver transplantation could be the last choice for complicated case, especially in combination with severe complications, like Budd-Chiari syndrome.
