ABSTRACT

@#The aim of this review was to document the recently reported prevalence and risk factors for chronic obstructive pulmonary disease (COPD) in the last ten years. A scoping review of studies released between 2011 and 2021 was done. The main findings on selected studies’ prevalence and risk factors were summarised. Thirty-seven studies in total were chosen. The overall data on COPD prevalence was 1.3-36.7%, and the average incidence rate was 9.1%. The risk factors of COPD prevalence were identified as unchangeable risk factors (gender, age, family history of respiratory and cardiovascular disease, high blood pressure, and environmental temperature and humidity) and changeable risk factors (outdoor and indoor air pollution, cigarette smoking, occupational exposure, low education, low household income, obesity, underweight, physical inactivity, and cooking method). The highest changeable risk factors were cigarette smoking, indoor air pollution, and occupational exposure. In contrast, the lowest changeable risk factors were physical inactivity and cooking methods. Changeable risk factors significantly increase COPD risks. The COPD caused by household emissions from biofuel cooking in low-income rural areas deserves attention. Emphasis on healthy lifestyle interventions and economic and educational policies to reduce environmental impacts may prevent COPD.

ABSTRACT

Objective:To investigate the postoperative complications and in-hospital mortality of reoperative cardiac surgery, and to explore the feasibility and safety of reoperative cardiac surgery.Methods:The baseline data and clinical information of patients undergoing cardiac surgery in Nanjing First Hospital from November 2012 to November 2021 were retrospectively conducted, and they were divided into the reoperative cardiac surgery group and the primary surgery group according to whether they underwent reoperative cardiac surgery using a propensity score analysis. The intraoperative indicators, postoperative complications and in-hospital mortality were compared between the two groups after matching.Results:After propensity score analysis, 146 cases were included in each of the group. In terms of intraoperative indicators, the cardiopulmonary bypass time [(141.48±47.88)min vs.(105.31±33.56)min], aortic occlusion time [87.0(70.5, 113.3)min vs. 71.5(53.0, 92.0)min], ICU stay time[2( 1, 4)days vs. 2(1, 2)days], postoperative drainage volume [750(460, 1300)ml vs. 610(410, 840)ml], postoperative transfusion of red blood cells [0(0, 3.5)U vs. 0(0, 2)U], the reoperative cardiac surgery group increased with statistically significant differences( P<0.05). Postoperative complications, the two groups had postoperative hypoxemia [15(10.3%) vs. 6(4.1%)], acute kidney injury [10(6.8%) vs. 0(0)], postoperative infection [24(16.4%) vs. 4(2.7%)], cerebral complications [7(4.8%) vs. 1(0.7%)] )], the incidence rate in the reoperative cardiac surgery group was higher with statistically significant differences( P<0.05). There was no significant difference in in-hospital mortality[7(4.8%) vs. 4(2.8%)]( P>0.05). Conclusion:The time of reoperative cardiac surgeryis is longer, postoperative recovery is slower, and postoperative complication rate is higher, but does not increase in-hospital mortality.

ABSTRACT

Ferroptosis is a new form of regulated cell death discovered in recent years, which is iron-dependent cell death characterized by peroxidation of polyunsaturated fatty acid phospholipids. Recent studies have shown that radiotherapy can induce ferroptosis in cancer cells via ionizing radiation. Targeting ferroptosis plays a synergistic role in tumor suppression with radiation, which not only further deepens the connotation of radiobiology, but also provides a new perspective for tumor radiosensitization. This review systematically summarizes the occurrence and defense of ferroptosis, focusing on the key role of ferroptosis in the radiobiological effects of tumor cells and the potential application of ferroptosis in radiosensitization.

ABSTRACT

Objective:To formulate a ladder type early activity program in order to provide a theoretical and practical basis for improving the current activity status of tumor patients with pulmonary embolism.Methods:This research was conducted experimentally. A total of 92 tumor patients diagnosed as pulmonary embolism from January 1, 2021 to March 31, 2022 in Sichuan Cancer Hospital were divided into control group and experimental group with 46 cases each by random number table method. In the control group, a routine activity program was carried out, and the patients were confined to bed for 7 days. The experimental group obtained the best evidence of early pulmonary embolism activity plan through evidence-based nursing, formed a nurse-led ladder type early pulmonary embolism activity team, and finally constructed and implemented the ladder type early activity plan. The mortality rate, new thrombosis in ICU for 3 days and 7 days, length of stay in ICU and patients′ comfort were compared between the two groups.Results:The mortality rates within 30 days after the diagnosis of pulmonary embolism were 4.35% (2/46) and 2.17% (1/46) respectively in the control group and the experimental group, with no significant difference between the two groups ( χ2=0.35, P>0.05). The rates of new thrombosis were 15.22% (7/46) and 26.09% (12/46) in the control group, and 4.35% (2/46) and 4.35% (2/46) in the experimental group, respectively at 3 and 7 days after ICU admission, with a significant difference between the two groups at 7 days after ICU admission ( χ2=8.43, P<0.05). The length of stay in ICU and the score of General Comfort Questionnaire (GCQ) were (15.74 ± 11.11) days and (64.30 ± 15.54) points in the experimental group, respectively, while those in the control group were (11.07 ± 5.63)days and (73.84 ± 11.73) points, respectively. The difference between the two groups was statistically significant ( t=-2.55, -3.32, both P<0.05). Conclusions:The evidence-based ladder type early activity program for patients with pulmonary embolism caused by tumor will not increase the mortality of patients, but can ensure the safety of patients, reduce the incidence of new thrombosis and the length of ICU stay, improve the comfort of patients during the treatment of pulmonary embolism. It is worthy of clinical application.

ABSTRACT

Objective To explore the prognostic value of pretreatment hematological indicators in children and adolescents with nasopharyngeal carcinoma. Methods We performed a retrospective analysis on the medical records of 79 children and adolescents (≤20 years old) with nasopharyngeal carcinoma. Before treatment, all patients underwent hematological tests, and patients received intensity-modulated radiotherapy alone or intensity-modulated radiotherapy combined with chemotherapy, targeted, and other comprehensive treatment modes. The follow-up endpoints were overall survival (OS) and progression-free survival (PFS). Results Age≤14 years, no concurrent chemotherapy, pretreatment hematological indicators (high NLR, high PLR, high LDH, and high LAR) were associated with poor OS and PFS in children and adolescents with nasopharyngeal carcinoma (all P < 0.05). No concurrent chemotherapy and high LAR before treatment were independent adverse prognostic factors for OS in children and adolescents with nasopharyngeal carcinoma. Conclusion High NLR, high PLR, high LDH, and high LAR of pretreatment hematological indicators are associated with poor OS and PFS. Meanwhile, high LAR before treatment is an independent adverse prognostic factor for OS in children and adolescents with nasopharyngeal carcinoma.

ABSTRACT

OBJECTIVE@#To investigate the expression and clinical significance of soluble Fas (sFas) and sFasL in patients with secondary hemophagocytic lymphohistiocytosis (sHLH).@*METHODS@#From September 2015 to December 2020, 86 sHLH patients who met the HLH2004 diagnostic criteria were collected. They were divided into 55 cases in the MAHLH group and 31 cases in the NonMAHLH group according to the etiology. Thirty healthy persons were chosen as the normal control group, and 20 patients with systemic lupus erythematosus (SLE) were chosen as the disease control group. The expression levels of sFas and sFasL in the serum of patients with each group were detected by ELISA, and the clinical data were collected for statistical analysis. The significance of sFas and sFasL in sHLH was analyzed by ROC curve.@*RESULTS@#Serum levels of sFas and sFasL in patients with newly diagnosed sHLH were significantly higher than those in disease control group and normal control group (P<0.01). The levels of sFas and sFasL in MAHLH group were significantly higher than those in nonMAHLH (infection related HLH and autoimmune disease related HLH) group (P<0.01). The serum levels of sFas and sFasL in 17 newly treated patients with sHLH (17/86) after treatment were significantly lower than those before treatment (P<0.01). The serum sFas level in newly diagnosed sHLH patients was positively correlated with SF(r=0.35), sCD25(r=0.79) and sFasL(r=0.73). The serum sFasL level was positively correlated with SF(r=0.39), sCD25(r=0.64) and sFas(r=0.73). Compared with the NonMAHLH group, the area under the ROC curve was 0.707 (95% CI: 0.593-0.821) (P=0.0015). The optimal critical value for diagnosing MAHLH by sFas level was 12 743 pg/ml, and the sensitivity and specificity were 70.9% and 71% respectively. Compared with the NonMAHLH group, the area under the ROC curve was 0.765(95% CI: 0.659-0.87)(P<0.01). The median OS time of sFas high expression group (≥16798.5 pg/ml) and sFasL high expression group (≥4 785 pg/ml) was significantly shorter than that of the low expression group (P<0.001).@*CONCLUSION@#Serum levels of sFas and sFasL can be used for the early diagnosis and differential diagnosis of sHLH disease, and are the factor related to the poor prognosis of sHLH.

ABSTRACT

A case of cicatricial female pattern hair loss was reported. A 36-year-old female patient presented with gradually aggravated hair loss for more than 10 years. Skin examination showed diffuse hair thinning on the scalp, thin and soft hairs, and some pencil eraser-sized areas of focal atrichia. TrichoScan examination revealed markedly decreased hair density on the forehead, variability in hair diameter greater than 20%, and increased proportions of vellus hairs. Dermoscopic examination showed increased numbers of vellus hairs, plenty of focal atrichia areas measuring 3 - 5 mm in diameter, loss of some follicular ostia, and confluent white dots. Histopathological examination of vertical and transverse scalp sections showed predominantly distributed miniaturized hair follicles with lichenoid folliculitis around the infundibulum and isthmus, concentrically layered perifollicular fibrosis, a marked decrease in the number of hair follicles compared with healthy people of the same age, increased proportions of vellus hairs, a large number of miniaturized hair follicles and follicular streamers, and formation of follicular micro-scars. The patient was diagnosed with cicatricial female pattern hair loss. She received topical treatment with 5% minoxidil liniment once a day, and alternate treatment with topical tacrolimus ointment and clobetasol propionate ointment, as well as oral spironolactone at a dose of 20 mg twice a day and compound glycyrrhizin capsules at a dose of 50 mg thrice a day. After half a year of treatment, there was no marked aggravation of hair loss, and the follow-up continued.

ABSTRACT

Objective:To determine the safety of prophylactic irradiation dose CTV 60Gy optimized to CTV 50Gy for II b region in patients with stage N 0-N 1 nasopharyngeal carcinoma (NPC) and the dose advantage and clinical value for parotid gland protection, and to understand the diagnostic value of PET-CT and diffusion-weighted imaging (DWI) for suspicious positive lymph nodes in the neck (5 mm≤maximum short diameter<10 mm). Methods:Clinical data of 157 patients with primary non-metastatic NPC (N 0-N 1) admitted to our hospital from June 2015 to March 2017 were retrospectively analyzed. 104 patients underwent II b clinical target volume optimization guided by multimodal imaging system. Survival analysis was performed by Kaplan - Meier method. Univariate/multivariate regression analysis was performed to analyze the pattern of cervical lymph node recurrence. Paired t-test was used to compare the differences in target volume and parotid gland dose parameters before and after dose optimization. Results:Sixty patients underwent single-neck optimization in stage N 1, 25 patients received double-neck optimization (only those with retropharyngeal lymph node metastasis), and 19 patients underwent double-neck optimization in stage N 0. Three patients had cervical regional recurrence, all in-field. The 5-year overall survival rate was 93.3%. The lymph node recurrence-free survival rate, local recurrence-free survival rate, distant metastasis-free survival rate and disease-free survival rate were 97.1%, 91.3%, 88.5% and 80.8%, respectively. Cervical lymph node recurrence was associated with local recurrence in the nasopharynx, regardless of retropharyngeal lymph node status. Fourteen patients had suspicious positive cervical lymph nodes in II b region, with a mean maximum short diameter of 7.1 (5~9) mm on the largest cross-sectional plane, and 11 of them were positive on PET-CT, with a mean SUV max of 2.96 (2.5~3.3). There was no significant difference in GTV after optimization ( P>0.05). D mean, D max, D 50% and V 26Gy of parotid gland were significantly lower than those of conventional plan (all P<0.01). Conclusions:It is safe to optimize CTV 60Gy to CTV 50Gy in II b region in patients with N 0-N 1 NPC, and the exposure dose to normal tissues around the parotid gland and neck is significantly reduced. For small lymph nodes that do not meet the diagnostic criteria, it needs to be individualized in combination with multimodality imaging systems, such as PET-CT and DWI.

ABSTRACT

Objective:The respiratory waveform of lung cancer patients based on 4D-CT respiratory gating was analyzed to evaluate the accuracy of gating during radiotherapy, and to explore the off-target in the 4D-CT respiratory gating radiotherapy.Methods:Clinical data of 18 patients with lung cancer admitted to Radiotherapy Department of Jiangsu Cancer Hospital were collected to obtain the respiratory waveform data during 4D-CT respiratory gating radiotherapy. The waveform in each treatment working cycle was compared with the waveform in 4D-CT scan to study whether there was a possibility of the off-target in the treatment of lung cancer patients.Results:There were 154 treatment sessions and 20,790 treatment breathing cycles in 18 patients, among which the threshold of gated opening beam miss amplitude (Δm-en) was greater than 0 in 95 treatment breathing cycles in 7 patients, accounting for 0.46% of all breathing cycles, and the threshold of gated closing beam miss amplitude (Δm-dis) was greater than 0 in 1419 treatment breathing cycles in 13 patients, accounting for 6.83% of all cycles. Among the 13 patients withΔm-dis greater than 0, actual tumor range of motion (R G) was greater than the sum of the value of target margin (M) and the value of plan tumor range of motion (R T) in 7 patients, R G was more than 1.5 times of M+R T in 7 patients, and there were also 7 patients in the phase of rapid rise and fall of respiratory curve. The correlation efficients between R G-M-R T and the percentage of beam on miss phase (T en%) and the percentage of beam closing off phase (T dis%) were 0.41 and 0.57, respectively. Conclusion:When R G is more than 1.5 times of M+R T value and the gating beam on phase contains the phases in the rapid rise and fall of the respiratory curve, the possibility of the off-target during radiotherapy is significantly increased.

ABSTRACT

Aim To investigate the eorrelation between angiotensin II (Ang II ) level and clinical indicators in patients with rheumatoid arthritis ( HA) , and to determine the therapeutic effect of angiotensin receptor blockers ( ARBs).Methods Plasma samples and personal information were collected from HA patients admitted to our hospital from 2019 to 2021.The level of Ang II in plasma was determined by ELISA to elucidate the correlation between plasma Ang II level and the severity of HA.The pathological changes of synovi-al tissues and T eells subtype in different groups of HA patients were determined by pathological examination and flow cytometry.A rat model of collagen-induced arthritis (CIA) was established and the pathological examination was used to confirm that valsartan could alleviate the disease course in the CIA animal model.Results Compared with control group, the plasma level of Ang II in HA patients significantly increased.After therapy with oral ARBs plasma Ang H levels and anti - cyclic citrullinated peptide antibody ( CCP) titre were significantly lower than those untreated HA patients.The level of Ang II in plasma was positively correlated with CCP and the number of monocytes, but negatively with number of RBC and hemoglobin content.Staining of synovial tissue with HE and Masson found that patients with HA had significant synovial proliferation, pannus formation , and numerous inflammatory cell infiltrates compared with control patients.Immunohistochemical results showed significant infiltration of CD4 4 T cells in synovial tissues of HA patients.Western blot and immunofluorescence analysis showed that the expression of angiotensin type 1 receptor ( ATI R ) was significantly up-regulated in CD4 + T cells and synovial tissues of HA patients.The results of animal experiments showed that valsartan harl therapeutic effect on CIA rats and could delay the disease process of CIA.Conclusions Plasma Ang II level is positively correlated with CCP level and HA severity.ARBs can down-regualte CCP level and delay disease progression in HA patients.Animal experiments showed that valsartan blocks the combination of Ang H and ATI R and has therapeutic effect on a CIA rat model.This study provides the theoretical and experimental basis for ARBs to become the preferred antihypertensive drugs for HA patients with hypertension.

ABSTRACT

The motion of the tumor limits further improvement in the accuracy of radiotherapy. Real-time monitoring and tracking of tumor location is an emerging technology to improve the accuracy of tumor radiotherapy. According to the adopted methods, it can be broadly divided into non-radiation-based and radiation-based systems. The former system includes ultrasound guidance, nuclear magnetic resonance guidance, electromagnetic tracking, optical image guidance, artificial intelligence-based technologies, and the latter system consists of KV, MV-grade X-ray imaging system and CT-based guidance system. In this review, research progresses on real-time tumor monitoring and tracking technology in radiotherapy, respective advantages and disadvantages and current clinical application were summarized.

ABSTRACT

Extranodal natural killer/T-cell lymphoma (ENKTCL) is the subtype of non-Hodgkin lymphoma with high heterogeneity and invasiveness. Though most ENKTCL patients are present as early-stage at diagnosis, clinical prognosis significantly differs due to the limitations of clinical staging. Radiotherapy (RT) and chemotherapy (CT) are the first-line treatments for early ENKTCL patients. However, there is no consensus on the combined modalities of RT and CT, and their optimal strategy. With the continuous renewal of clinical staging and prognostic models, early-stage ENKTCL patients tend to accept risk-adapted treatment with proper stratification. In this review, the latest research progresses on clinical staging, prognostic models and treatment were retrospectively analyzed, aiming to provide references for clinical decision-making.

ABSTRACT

Varicose great saphenous vein is a common disease of vascular surgery. The treatment needs of a large number of patients and the progress of surgical techniques provide the necessity and feasibility for the active implementation of day surgery. Endovenous thermal closure techniques (laser closure and radiofrequency ablation) and non-thermal, non-tumescent techniques have the advantages of less trauma, faster recovery and fewer complications, and the effective rate and recurrence rate are not inferior to ligation and stripping. Sclerotherapy and phlebectomy are important auxiliary techniques.This paper analyzes and compares the technical characteristics and effectiveness of ambulatory surgeries for varicose great saphenous vein.

ABSTRACT

Indoleamine 2,3-dioxygenase 1 (IDO1) is the rate-limiting enzyme in the degradation of tryptophan to kynurenine. IDO1 is highly expressed in some tumor tissues. IDO1 can deplete tryptophan in tumor microenvironment, inhibit T cell function, and mediate the immune escape of tumor cells. Thus, IDO1 is considered a potential target of tumor immunotherapy. Currently, there are several IDO1 inhibitors in clinical research studies. The mechanism of IDO1-mediated tumor immune escape and the structure of IDO1 inhibitors are summarized in this review.

ABSTRACT

To study the effect of anemoside B4 on rats with chronic obstructive pulmonary disease (COPD).Seventy-two SD male rats were randomly divided into blank group and model group.The method of exposure to cigarette smoke and combined with lipopolysaccharide (LPS) was used to replicate the rat model of COPD.After the model was maintained for 5 weeks,the rats were randomly divided into model group,dexamethasone group (0.81 mg·kg~(-1)) and anemoside B4 low,medium and high (2,4,8 mg·kg~(-1)) dose groups,a group of 12 animals were administered,and then the administration was started.The administration was maintained until the28th day,and the pulmonary function parameters of rats were measured by an animal pulmonary function instrument.After testing the rat lung function parameters,immediately draw rat alveolar lavage fluid (BALF),and use high-throughput protein chip technology to determined the expression levels of inflammatory cytokines in rat BALF.HE staining was used to observe the general pathological changes of rat lung and tracheal tissue.Masson staining was used to observe the collagen deposition in rat lung tissue.Real-time q PCR method was used to determine the mRNA expression level of related genes in rat lung tissue.Western blot method was used to determine the expression levels of related proteins in rat lung tissues.According to the findings,compared with the model group,the dexamethasone group and the anemoside B4 drug groups had different degrees of increase in the lung function parameters of rats (P<0.01,P<0.05),improved the expression level of inflammatory cytokines in the BALF of rats to varying degrees (P<0.01,P<0.05),and improved the pathological structure of rat lung tissue to varying degrees.Relative mRNA expressions of matrix metalloproteinase 2 (MMP-2),matrix metalloproteinase 12 (MMP-12),matrix metalloproteinase inhibitor 1 (TIMP-1),interleukin-6 (IL-6),and transforming growth factor-β1 (TGF-β1) were significantly reduced (P<0.01);whereas relative mRNA expressions of matrix metalloproteinase 9(MMP-9) and matrix metalloproteinase inhibitor 2 (TIMP-2) were increased significantly (P<0.01).The mRNA and protein expression levels of T-box transcription factor (T-bet),interleukin-12 (IL-12) and signal transducer and activator of transcription 4(STAT4) reduced to varying degrees (P<0.01,P<0.05).The mRNA of transcription factor GATA3 (binding protein-3),interleukin-4 (IL-4) and signal transducer and activator of transcription 6 (STAT6) in rat lung tissues and the protein expression levels of IL-4 and STAT6 were increased to varying degrees (P<0.01,P<0.05).In conclusion,anemoside B4 has a certain protective effect on COPD rats caused by cigarette smoke exposure and combined with LPS.The mechanism of action may be related to the regulation of IL-12/STAT4 and IL-4/STAT6 signaling pathways.

ABSTRACT

Objective:To explore the relationship between iodine and hypothyroidism.Methods:Patients with primary hypothyroidism (hypothyroidism group) and healthy people (control group) from Linfen City who first came to the Affiliated Hospital of Shanxi Institute for Endemic Disease Prevention and Treatment in 2017 and 2018 were selected as the research subjects. One random urine sample and fasting venous blood sample were collected from the research subjects. The levels of urinary iodine, blood iodine and serum total triiodothyronine (TT 3), total thyroxine (TT 4), free triiodothyronine (FT 3), free thyroxine (FT 4), thyroid stimulating hormone (TSH), anti-thyroglobulin antibody (TgAb) and anti-thyroid peroxidase antibody (TPOAb) were detected. According to the results of TSH level, hypothyroidism group was divided into hypothyroidism Ⅰ group (TSH≥10.00 mU/L) and hypothyroidism Ⅱ group (4.20 mU/L < TSH < 10.00 mU/L), and they were compared with control group (0.27 mU/L≤TSH≤4.20 mU/L). Results:A total of 97, 96 and 175 research subjects were included in hypothyroidism Ⅰ group, hypothyroidism Ⅱ group and control group, respectively. There was no significant difference in urinary iodine levels among the three groups ( H = 0.631, P > 0.05). The blood iodine levels [(40.70 ± 21.08), (58.59 ± 14.55), (59.50 ± 11.89) μg/L] in the three groups were significantly different ( F = 50.559, P < 0.01), and the blood iodine level in hypothyroidismⅠgroup was lower than that in hypothyroidism Ⅱ group and control group ( P < 0.01). The levels of TT 3 [median (interquartile range): 1.59 (0.99, 2.05), 2.25 (1.98, 2.59), 2.14 (1.89, 2.49) nmol/L], TT 4 [35.18 (16.06, 70.23), 105.68 (83.38, 133.19), 107.18 (89.92, 128.30) nmol/L], FT 3 [3.48 (1.94, 4.52), 5.01 (4.57, 5.50), 5.02 (4.64, 5.55) pmol/L] and FT 4 [7.14 (3.12, 10.76), 15.31 (13.87, 17.11), 16.69 (14.87, 18.20) pmol/L] in the three groups were significantly different ( H = 66.197, 142.461, 94.508, 166.557, P < 0.01). After further pairwise comparison, the levels of TT 3, TT 4, FT 3, and FT 4 in hypothyroidism Ⅰ group were significantly lower than those in hypothyroidism Ⅱ group and control group ( P < 0.01). The levels of TgAb and TPOAb in the three groups were significantly different ( H = 85.507, 101.726, P < 0.01). After further pairwise comparison, the levels of TgAb and TPOAb in hypothyroidismⅠgroup were significantly higher than those in hypothyroidism Ⅱ group and control group ( P < 0.01); and the levels of TgAb and TPOAb in hypothyroidism Ⅱ group were significantly higher than those in control group ( P < 0.01). The correlation analysis showed that urinary iodine was positively correlated with blood iodine ( r = 0.170, P < 0.05); blood iodine was positively correlated with TT 3, TT 4, FT 3, and FT 4 levels ( r s = 0.484, 0.594, 0.383, 0.509, P < 0.01), and it was negatively correlated with TSH level ( r s = - 0.373, P < 0.01). Conclusion:Hypothyroidism patients with TSH≥10.00 mU/L may have low blood iodine level.

ABSTRACT

@#Introduction: The purpose of this study was to investigate the effect of incremental running intensity on heart rate variability during recovery in university-level male football athletes. Methods: Twenty healthy males aged between 19-26 years old were randomly assigned to control (no running) and intervention (modified Bruce protocol running) groups. Analyses were performed at pre-exercise, 24, 48, and 72 h post-exercise. The low-frequency (LF) and high frequency (HF) in peak, absolute power and normalised unit (n.u.), as well as LF/HF ratio, were assessed. Results: Intervention group showed a reduced LF n.u. response (ES=1.69) whereas HF n.u. showed the opposite response (ES=1.51) at 24 h post-exercise. The intervention group showed a significant difference in the LF/HF ratio at 48 h post-exercise (p=0.002; ES=1.05). Conclusion: These findings demonstrated that incremental type of exercise influence both sympathetic and parasympathetic response for at least 48 h post-exercise.

ABSTRACT

Objective To explore the correlation of pretreatment EBV DNA load, EBV EA-IgA and VCA-IgA antibodies levels with the clinical characteristics, curative effect and prognosis of the patients with early-stage extranodal nasal-type NK/T-cell lymphoma (ENKTCL). Methods We analyzed the clinical features and prognostic factors of 78 ENKTCL patients. Results Positive rates of pretreatment EBV DNA, VCA-IgA and EA-IgA were 43.6%, 20.5% and 14.1%, respectively. EBV DNA was significantly associated with Ann Arbor stage, primary site, PTI and non-CR (all P < 0.05). VCA-IgA and EA-IgA were related to positive EBV DNA and non-CR (all P < 0.05). Multivariate analysis showed that age, EBV DNA and non-CR were independent prognostic factors for OS (all P < 0.05); age, EBV DNA, primary site and non-CR were independent prognostic factors for PFS (all P < 0.05). Conclusion The pretreatment positive EBV DNA is related to advanced Ann Arbor stage, PTI, primary extra-nasal subtypes of upper aerodigestive tract and poor response to treatment. The elevated levels of EA-IgA and VCA-IgA are related to positive EBV DNA and poor response to treatment. Pretreatment EBV DNA could be used for risk stratification and prognosis prediction of ENKTCL, while EA-IgA and VCA-IgA play limited role in guiding the prognosis of ENKTCL.

ABSTRACT

To systematically evaluate the clinical efficacy and safety of Lianhua Qingwen in the treatment of adult pneumonia. The randomized controlled trial of Lianhua Qingwen combined with conventional Western medicine in the treatment of pneumonia were retrieved from PubMed, EMbase, Wanfang database, VIP database, and CNKI from the establishment of database to March 2020. Two researchers independently conducted literature screening and data extraction, and the third researcher was in charge of arbitration in case of any disagreement. Outcome indicators included total clinical effective rate, symptom improvement time, and incidence of adverse events. R 3.6.1 was used for Meta-analysis, and RevMan 5.3 was used for quality evaluation. Twenty-two studies were included, with a total of 2 007 patients, including 1 017 patients in the experimental group and 990 patients in the control group. The results showed that the total clinical effective rate of the experimental group was higher than that of the control group(RR=1.11, 95%CI[1.08, 1.15], P<0.001), and the antifebrile time(MD=-1.81, 95%CI[-2.42,-1.21], P<0.001), cough duration(MD=-2.32, 95%CI[-2.89,-1.76], P<0.001), rale duration(MD=-2.19, 95%CI[-2.74,-1.63], P<0.001), imaging recovery time(MD=-2.17, 95%CI[-2.76,-1.58], P<0.001) and post-treatment CRP(MD=-4.07, 95%CI[-6.39,-1.75], P<0.001] were all significantly lower than those of the control group. However, it did not proved that the experimental group was safer than the control group(RR=0.84, 95%CI[0.57, 1.24], P=0.382). The results confirmed that Lianhua Qingwen combined with conventional Western medicine in the treatment of pneumonia could improve the clinical treatment efficiency, shorten the time of fever, cough, rale disappearance and imaging recovery, improve CRP index and accelerate the recovery of pneumonia patients. However, the literatures included in this study had a low quality, and the conclusions still need to be further confirmed by more high-quality, multi-center, rigorously designed randomized controlled trial.
