ABSTRACT

Objective To explore the influencing factors of bone mineral density (BMD) in obese children in Qianjiang area and analyze the correlation between BMD and insulin resistance. Methods The data on pediatric cases from the outpatient department of Jianghan Oilfield General Hospital in Qianjiang from January 2018 to December 2022 were collected. A total of 183 obese children who met the inclusion and exclusion criteria were included in the study and selected in the observation group. A total of 352 children undergoing physical examination during the same period were selected as the control group. Results The body mass, waist circumference, waist to hip ratio, and BMI of obese children were significantly higher than those of the control group (P<0.001). Biochemical indexes including FBG, FINS, Home-IR, ALP, and LDL-C in obese children were significantly higher than those in the control group (P<0.05), while bone mineral density, Ca, P, sOC and HDL-C were significantly lower than those in the control group (P<0.001). The bone mineral density of obese children was significantly correlated with their exercise intensity, sunshine exposure duration, sitting time, intake of milk and dairy products, intake of sweets, supplementation of trace elements, BMI, Home-IR, and sex (all P<0.05). BMI, Home-IR, sex, exercise intensity, and sunshine exposure length were independent risk factors affecting bone mineral density of obese children (all P<0.05). Bone mineral density was negatively correlated with BMI and Home-IR (P=0.028 and0.017, respectively), and positive correlation with exercise intensity and sunlight exposure (P=0.033). Conclusion BMD of obese children in Qianjiang area is affected by gender, body mass index, diet, vitamin intake, and physical activity, and is negatively correlated with insulin resistance. Home-IR can be used as a reference for screening BMD of obese children.

ABSTRACT

Objective To investigate the prevalence of Echinococcus infection in small mammals in Shiqu County, Sichuan Province from 2015 to 2020, so as to provide insights into echinococcosis control in Shiqu County. Methods One setting with frequent activity of small mammals was sampled as the survey site from each of 9 townships where human alveolar echinococcosis was hyperendemic, in Shiqu County, Sichuan Province from 2015 to 2020. Two quadrats measuring 50 m × 50 m were assigned in each survey site during the period between July and August from 2015 to 2020 to capture all small mammals in quadrats, and the species of small mammals were identified by morphological characteristics. All captured small mammals were dissected in the field and Echinococcus infection was identified by visual examinations. The affected organs of Echinococcus-infected small mammals were collected, and Echinococcus infection was detected using PCR assay, with Echinococcus species characterized. The prevalence of Echinococcus infection was calculated in small mammals, and the trends in the prevalence of Echinococcus infection were analyzed during the period from 2015 to 2020. In addition, the prevalence of Echinococcus infection was compared in small mammals using visual examinations and PCR assay. Results A total of 2 692 small mammals were captured in the survey sites of Shiqu County from 2015 to 2020, and morphology characterized 1 360 Microtus fuscus (50.52%) and 1 332 Plateau pika (49.48%). The prevalence rates of Echinococcus infection were 35.63%, 19.16%, 21.41%, 8.40%, 7.68% and 4.44% by visual examinations and 18.96%, 5.36%, 5.61%, 4.58%, 3.30% and 0.37% by PCR assay in small mammals in Shiqu County from 2015 to 2020, both showing a tendency towards a decline year by year (χ2 = 215.024 and 117.045, both P values < 0.001). The prevalence of Echinococcus infection was significantly higher in small mammals by visual examinations than by PCR assay during the period from 2015 to 2020 except in 2018 (χ2= 33.597, 21.815, 51.373, 17.268 and 9.537, all P values < 0.01). PCR assay detected a reduction in the prevalence of E. multilocularis infection from 10.21% to 0.37% and a reduction in the prevalence of E. shiquicus infection from 8.75% to 0 in small mammals in Shiqu County from 2015 to 2020, both appearing a tendency towards a decline year by year (χ2 = 117.045 and 43.436, both P values < 0.001). In addition, the prevalence of E. multilocularis and E. shiquicus infections reduced from 15.19% to 0.45% and from 8.23% to 0 in M. fuscus, and the prevalence of E. multilocularis and E. shiquicus infections reduced from 7.76% to 0 and from 9.01% to 0 in P. pika in Shiqu County from 2015 to 2020. Conclusions M. fuscus and P. pika were dominant species of small mammals in Shiqu County, Sichuan Province from 2015 to 2020, and E. multilocularis infection was mainly found in M. fuscus and E. shiquicus infection mainly found in P. pika. The prevalence of Echinococcus infection appeared a tendency towards a decline in both M. fuscus and P. pika year by year during the period from 2015 to 2020.

ABSTRACT

Objective: To investigate the clinical presentation and genetic characteristics of malignant infantile osteopetrosis. Methods: This was a retrospective case study. Thirty-seven children with malignant infantile osteopetrosis admitted into Beijing Children's Hospital from January 2013 to September 2022 were enrolled in this study. According to the gene mutations, the patients were divided into the CLCN7 group and the TCIRG1 group. Clinical characteristics, laboratory tests, and prognosis were compared between two groups. Wilcoxon test or Fisher exact test were used in inter-group comparison. The survival rate was estimated with the Kaplan-Meier method and the Log-Rank test was used to compare the difference in survival between groups. Results: Among the 37 cases, there were 22 males and 15 females. The age of diagnosis was 0.5 (0.2, 1.0) year. There were 13 patients (35%) and 24 patients (65%) with mutations in CLCN7 and TCIRGI gene respectively. Patients in the CLCN7 group had an older age of diagnosis than those in the TCIRGI group (1.2 (0.4, 3.6) vs. 0.4 (0.2, 0.6) years, Z=-2.60, P=0.008). The levels of serum phosphorus (1.7 (1.3, 1.8) vs. 1.1 (0.8, 1.6) mmol/L, Z=-2.59, P=0.010), creatine kinase isoenzyme (CK-MB) (457 (143, 610) vs. 56 (37, 82) U/L, Z=-3.38, P=0.001) and the level of neutrophils (14.0 (9.9, 18.1) vs. 9.2 (6.7, 11.1) ×109/L, Z=-2.07, P=0.039) at diagnosis were higher in the CLCN7 group than that in the TCIRG1 group. However, the level of D-dimer in the CLCN7 group was lower than that in the TCIRGI group (2.7 (1.0, 3.1) vs. 6.3 (2.5, 9.7) μg/L, Z=2.83, P=0.005). After hematopoietic stem cell transplantation, there was no significant difference in 5-year overall survival rate between the two groups (92.3%±7.4% vs. 83.3%±7.6%, χ²=0.56, P=0.456). Conclusions: TCIRGI gene mutations are more common in children with osteopetrosis. Children with TCIRGI gene mutations have younger age, lower levels of phosphorus, CK-MB, and neutrophils and higher level of D-dimer at the onset. After hematopoietic stem cell transplantation, patients with CLCN7 or TCIRGI gene mutations have similar prognosis.

ABSTRACT

A moxibustion device with the functions of auricular fumigation moxibustion and heat-sensitive moxibustion is designed. The smoke of the ignited moxa stick is used for the fumigation moxibustion at the external auditory canal, while the heat generated works on Dazhui (GV 14) for heat-sensitive moxibustion. The device consists of five parts, i.e. combustion chamber, smoke pipe, smoke processing chamber, power module and connector. It solves the limitations such as unpleasant experience in treatment, unfavorable temperature control, easy scalding and excessive manual dependence induced by usual fumigation moxibustion and during heat-sensitive moxibustion. This moxibustion device may improve the safety and convenience when delivering the treatment with fumigation moxibustion and heat-sensitive moxibustion, as well as the work efficiency of medical staff.

ABSTRACT

Objective: To analyze the characteristics of scientific papers in the field of global liver diseases published by Chinese scholars that were retracted for diverse reasons from the Retraction Watch database, so as to provide a reference to publishing-related papers. Methods: The Retraction Watch database was retrieved for retracted papers in the field of global liver disease published by Chinese scholars from March 1, 2008 to January 28, 2021. The regional distribution, source journals, reasons for retraction, publication and retraction times, and others were analyzed. Results: A total of 101 retracted papers that were distributed across 21 provinces/cities were retrieved. Zhejiang area (n = 17) had the most retracted papers, followed by Shanghai (n = 14), and Beijing (n = 11). The vast majority were research papers (n = 95). The journal PLoS One had the highest number of retracted papers. In terms of time distribution, 2019 (n = 36) had the most retracted papers. 23 papers, accounting for 8.3% of all retractions, were retracted owing to journal or publisher concerns. Liver cancer (34%), liver transplantation (16%), hepatitis (14%), and others were the main areas of retracted papers. Conclusion: Chinese scholars have a large number of retracted articles in the field of global liver diseases. A journal or publisher chooses to retract a manuscript after investigating and discovering more flawed problems, which, however, require further support, revision, and supervision from the editorial and academic circles.

ABSTRACT

Objective: To evaluate the effectiveness of a risk-adapted colorectal cancer screening strategy constructed utilizing genetic and environmental risk score (ERS). Methods: A polygenic risk score (PRS) was constructed based on 20 previously published single nucleotide polymorphisms for colorectal cancer in East Asian populations, using 2 160 samples with MassARRAY test results from a multicenter randomized controlled trial of colorectal cancer screening in China. The ERS was calculated using the Asia-Pacific Colorectal Screening Score system. Logistic regression was used to analyze the association between PRS alone and PRS combined with ERS and colorectal neoplasms risk, respectively. We also designed a risk-adapted screening strategy based on PRS and ERS (high-risk participants undergo a single colonoscopy, low-risk participants undergo an annual fecal immunochemical test, and those with positive results undergo further diagnostic colonoscopy) and compared its effectiveness with the all-acceptance colonoscopy strategy. Results: The high PRS group had a 26% increased risk of colorectal neoplasms compared with the low PRS group (OR=1.26, 95%CI: 1.03-1.54, P=0.026). Participants with the highest PRS and ERS were 3.03 times more likely to develop advanced colorectal neoplasms than those with the lowest score (95%CI: 1.87-4.90, P<0.001). As the risk-adapted screening simulation reached the third round, the detection rate of the PRS combined with ERS strategy was not statistically different from the all-acceptance colonoscopy strategy (8.79% vs. 10.46%, P=0.075) and had a higher positive predictive value (14.11% vs. 10.46%, P<0.001) and lower number of colonoscopies per advanced neoplasms detected (7.1 vs. 9.6, P<0.001). Conclusion: The risk-adapted screening strategy combining PRS and ERS helps achieve population risk stratification and better effectiveness than the traditional colonoscopy-based screening strategy.

ABSTRACT

Urethral stricture is characterized by the chronic formation of fibrous tissue, leading to the narrowing of the urethral lumen. Despite the availability of various endoscopic treatments, the recurrence of urethral strictures remains a common challenge. Postsurgery pharmacotherapy targeting tissue fibrosis is a promising option for reducing recurrence rates. Although drugs cannot replace surgery, they can be used as adjuvant therapies to improve outcomes. In this regard, many drugs have been proposed based on the mechanisms underlying the pathophysiology of urethral stricture. Ongoing studies have obtained substantial progress in treating urethral strictures, highlighting the potential for improved drug effectiveness through appropriate clinical delivery methods. Therefore, this review summarizes the latest researches on the mechanisms related to the pathophysiology of urethral stricture and the drugs to provide a theoretical basis and new insights for the effective use and future advancements in drug therapy for urethral stricture.

ABSTRACT

OBJECTIVES@#This study aims to investigate the genome-wide DNA methylation and transcriptome expression profiles of peripheral blood mononuclear cells (PBMCs) in patients with systemic sclerosis (SSc) with interstitial lung disease (ILD), and to analyze the effects of DNA methylation on Wnt/β-catenin and chemokine signaling pathways.@*METHODS@#PBMCs were collected from 19 patients with SSc (SSc group) and 18 healthy persons (control group). Among SSc patients, there were 10 patients with ILD (SSc with ILD subgroup) and 9 patients without ILD (SSc without ILD subgroup). The genome-wide DNA methylation and gene expression level were analyzed by using Illumina 450K methylation chip and Illumina HT-12 v4.0 gene expression profiling chip. The effect of DNA methylation on Wnt/β-catenin and chemokine signal pathways was investigated.@*RESULTS@#Genome-wide DNA methylation analysis identified 71 hypermethylated CpG sites and 98 hypomethylated CpG sites in the SSc with ILD subgroup compared with the SSc without ILD subgroup. Transcriptome analysis distinguished 164 upregulated genes and 191 downregulated genes in the SSc with ILD subgroup as compared with the SSc without ILD subgroup. In PBMCs of the SSc group, 35 genes in Wnt/β-catenin signaling pathway were hypomethylated, while frizzled-1 (FZD1), mitogen-activated protein kinase 9 (MAPK9), mothers against DPP homolog 2 (SMAD2), transcription factor 7-like 2 (TCF7L2), and wingless-type MMTV integration site family, member 5B (WNT5B) mRNA expressions were upregulated as compared with the control group (all P<0.05). Compared with the SSc without ILD subgroup, the mRNA expressions of dickkopf homolog 2 (DKK2), FZD1, MAPK9 were upregulated in the SSc with ILD subgroup, but the differences were not statistically significant (all P>0.05). In PBMCs of the SSc group, 38 genes in chemokine signaling pathway were hypomethylated, while β-arrestin 1 (ARRB1), C-X-C motif chemokine ligand 10 (CXCL10), C-X-C motif chemokine ligand 16 (CXCL16), FGR, and neutrophil cytosolic factor 1C (NCF1C) mRNA expressions were upregulated as compared with the control group (all P<0.05). Compared with the SSc without ILD subgroup, the mRNA expressions of ARRB1, CXCL10, CXCL16 were upregulated in the SSc with ILD subgroup, but the differences were not statistically significant (all P>0.05).@*CONCLUSIONS@#There are differences in DNA methylation and transcriptome profiles between SSc with ILD and SSc without ILD. The expression levels of multiple genes in Wnt/β- catenin and chemokine signaling pathways are upregulated, which might be associatea with the pathogenesis of SSc.

ABSTRACT

@#Objective    To evaluate the survival results of surgical resection (SR) and CT-guided percutaneous ablation (PA) for stageⅠnon-small cell lung cancer (NSCLC). Methods    The PubMed, Web of Science, EMbase, The Cochrane Library, CNKI, VIP, Wanfang databases from inception to June 2021 were searched to collect comparative studies on the survival results between SR and CT-guided PA treatment for stageⅠNSCLC. RevMan 5.3 software was used for statistical analysis of data. Results    A total of 3 114 patients were included in 11 studies. The results of meta-analysis showed that compared with the PA group, the SR group had a higher 2-year postoperative overall survival (OS) rate (OR=1.44, 95%CI 1.00-2.06, P=0.05), 3-year postoperative OS rate (OR=2.37, 95%CI 1.47-3.81, P<0.001), 5-year OS rate (OR=1.64, 95%CI 1.19-2.28, P<0.01), 5-year progression-free survival rate after operation (OR=2.43, 95%CI 1.54-3.82, P<0.001) and lower local recurrence rate (OR=0.26, 95%CI 0.13-0.54, P<0.001). There were no statistical differences between the two groups in terms of 1-year postoperative OS rate, 1-year, 2-year, and 3-year tumor-related survival rates, 1-year, 2-year tumor-free survival rates, or distant postoperative recurrence rate (P>0.05). Conclusion    For patients with stageⅠNSCLC with optimal basic conditions, surgery is a more appropriate treatment. For patients who cannot withstand surgical injuries or refuse surgery, CT-guided PA is also a potential alternative treatment. However, this conclusion needs  to be verified by prospective controlled trials with larger sample sizes and a more rigorous design.

ABSTRACT

To investigate the effects of the S-curve leakage testing method on the detection of flexible endoscope and occurrence of medium to high-level faults of flexible endoscope. A convenience sampling method was used to study the information of endoscopic leak detection at the digestive endoscopic centre of the First Affiliated Hospital of Air Force Medical University. From July 2016 to December 2017, 58 endoscopes which received conventional leakage testing were set as the control group (29 116 tests). From January 2018 to June 2019, 56 endoscopes which received S-curve leakage testing were set as the observation group (28 112 tests). The results showed that the detection proportion of angular abnormalities in the observation group was higher than that in the control group [65.6% (59/90) VS 40.4% (36/89), χ2=11.330, P<0.001]. However, the detection proportion of medium to high-grade faults such as damaged charge coupled device (CCD) components and broken insertion section in the observation group was lower than that in the control group [0.04% (10/28 112) VS 0.08% (23/29 116), χ2=4.680, P=0.030]. Moreover, the overall maintenance cost was lower in the observation group than that in the control group (313.7 thousand yuan VS 942.6 thousand yuan). It is indicated that the S-curve leakage testing method can detect low-level endoscopic faults early such as angular abnormalities, and reduce the occurrence of medium to high-level endoscopic faults, which contributes to cost reduction and efficiency increase.

ABSTRACT

Objective:To explore any effect of the single- and dual-task treadmill training on the functioning of children with bilateral spastic cerebral palsy.Methods:Fifty children with bilateral spastic cerebral palsy were randomly divided into a single-task treadmill training group (the control group, n=25) and a dual-task treadmill training group (the observation group, n=25). All of the children also received routine rehabilitation training, and the control and observation groups also conducted single- and dual-task treadmill training in addition to the routine rehabilitation training, respectively. Before and after 2 months of treatment, each child′s gross motor functioning was quantified using sections D (standing) and E (walking, running and jumping) of the Gross Motor Function Measurement-88 (GMFM-88) instrument. Balance was quantified using the Pediatric Balance Scale (PBS) and walking mobility was quantified using a 1 minute walking test (1MWT). Modified and dual task Timed Up and Go (mTUG) tests and dual-task effects (DTE) tests were also administered. Results:There were no significant differences in average test scores between the two groups before the treatment. After the treatment significant improvement was observed in both groups. There was no significant difference between the two groups in terms of average GMFM-88, PBS and 1MWT scores, but significantly greater improvement was observed in the average dual-task mTUG and DTE results of the observation group.Conclusion:Both single- and dual-task treadmill training are effective supplements to routine rehabilitation training for children with bilateral spastic cerebral palsy. Dual-task treadmill training is more effective than the single-task version.

ABSTRACT

Objective:To investigate the clinical characteristics of patients with rheumatic diseases and abnormal liver function, as well as determine the proportion and severity of liver function abnormalities.Methods:Cross-sectional study. Data were collected from patients registered in the Chinese Rheumatism Date Center from 2011 to 2021. The rheumatic diseases analyzed in this study were rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), Sjogren syndrome (SS), ankylosing spondylitis (AS), and gout. Patient data, including demographic characteristics [ such as age, sex, body mass index,(BMI), and smoking history], liver function test results [including alanine aminotransferase (ALT), aspartate aminotransferase, alkaline phosphatase(ALP), and total bilirubin], and use of anti-rheumatic immune drugs and liver-protective drugs, were collected and compared between groups with normal and abnormal liver functions. In addition, the proportions of abnormal liver function were compared between sex and age groups.Results:A total of 116 308 patients were included in this study, including 49 659 with RA, 17 597 with SLE, 9 039 with SS, 11 321 with AS, and 28 692 with gout. The lowest proportion of liver function abnormalities was observed in patients with RA[11.02% (5 470/49 659)], followed by those with SS[17.97% (1 624/9 039)] and AS [18.22% (2 063/11 321) ], whereas patients with SLE [21.14% (3 720/17 597) ] and gout [28.73% (8 242/28 692)] exhibited the highest proportion of these abnormalities. Elevated ALT, mostly classified as grade 1, was the most commonly noted liver function abnormality, whereas elevated ALP was the least common. Some patients who took liver-protective drugs had normal liver function, with the lowest percentage observed in patients with gout [7.45% (36/483) ] and ranging from 21.7% to 30.34% in patients with RA, SLE, SS, and AS. The proportion of liver function abnormalities was higher in males than in females for all disease types [RA: 13.8%(1 368/9 906) vs. 10.3%(4 102/39 753); SLE: 33.6% (479/1 424) vs. 20.0% (3 241/16 173); SS: 25.4%(111/437) vs. 17.6%(1 513/8 602); AS: 20.1%(1 629/8 119) vs. 13.6% (434/3 202); and gout: 29.3% (8 033/27 394) vs. 16.1% (209/1 298)]. In RA, SLE, and AS, the proportions of liver function abnormalities were similar across all age groups. In SS, the proportion of liver function abnormalities increased with age [<40 years: 14.9%(294/1 979); 40-59 years: 18.1%(858/4 741); ≥60 years: 20.4%(472/2 319)], whereas a reversal of this trend was observed in gout [<40 years: 34.9%(4 294/12 320); 40-59 years: 25.5%(2 905/11 398);≥60 years: 21.0%(1 042/4 971)].Conclusions:The proportions of combined liver function abnormalities in patients with rheumatologic diseases were high, and the utilization rates of liver-protective drugs were low. It is necessary to pay more attention to monitoring patients′ liver function, timely administer liver-protective drugs, and optimize liver-protective regimens during the treatment of rheumatic diseases.

ABSTRACT

Objective:To evaluate the usability of Gafchromic HD-V2 film for dose dosimetry in the ultra-high dose-rate (UD) electron beam from a modified medical linac, and to investigate the response between the energy and dose-rate dependence to the film.Methods:The HD-V2 film was utilized to measure the average dose-rate of the UD electron beam. The measured result was compared with those by advanced Markus chamber and alanine pellets. And characteristics of the UD electron beam were also measured by HD-V2 film. Energy dependence of HD-V2 film at three beam energies (6 MV X-ray, 9 MeV and 16 MeV electron beam) was investigated by obtaining and comparing the calibration curves based on the clinical linear accelerator in the dose range of 10-300 Gy. The dose-rate dependence of HD-V2 film was also studied by varying the dose rate among 0.03 Gy/s, 0.06 Gy/s and 0.1 Gy/s, and range of 100-200 Gy/s.Results:The measured average maximum dose-rate of 9 MeV UD electron beam at source skin distance (SSD) 100 cm was approximately 121 Gy/s using HD-V2 film, consistent with the results by advanced Markus chamber and alanine pellets. The measured percentage depth dose (PDD) curve parameters of the UD electron beam were similar to the conventional 9 MeV beam. The off-axis dose distribution of the UD electron beam showed the highest central axis, and the dose was gradually decreased with the increase of off-axis distance. The energy dependence of HD-V2 film had no dependency of 6 MV and 9, 16 MeV while measuring the dose in the range from 20 to 300 Gy. The HD-V2 film had no significant dose-rate dependency at the dose rate of 0.03 Gy/s, 0.06 Gy/s and 0.1 Gy/s for the clinical linear accelerator. Likewise, there was also no dose-rate dependence in the range 100-200 Gy/s in the modified machine.Conclusion:HD-V2 film is suitable for measuring ultra-high dose rate electron beam, independent of energy and dose rate.

ABSTRACT

Objective:To compare the effects on DNA strand break induced by ultra-high dose rate (FLASH) electron beam and conventional irradiation, and investigate whether FLASH effect was correlated with a reduction of radiation response.Methods:Aqueous pBR322 plasmid was treated with FLASH (125 Gy/s) and conventional irradiation (0.05 Gy/s) under physioxia (4% O 2) and normoxia (21% O 2). Open circle DNA and linear DNA were detected by agarose gel electrophoresis, and the plasmid DNA damage was quantified with an established mathematical model to calculate the relative biological effect (RBE) of DNA damage. In some experiments, Samwirin A (SW) was applied to scavenge free radicals generated by ionizing radiation. Results:Under physioxia, the yields of DNA strand breakage induced by both FLASH and conventional irradiation had a dose-dependent manner. FLASH irradiation could significantly decrease radiation-induced linear DNA compared with conventional irradiation ( t=5.28, 5.79, 7.01, 7.66, P<0.05). However, when the aqueous plasmid was pretreated with SW, there was no difference of DNA strand breakage between FLASH and conventional irradiation ( P>0.05). Both of the yields of open circle DNA and linear DNA had no difference caused by FLASH and conventional radiotherapy at normoxia, but were significantly higher than those under physioxia. In addition, the yields of linear DNA and open circle DNA induced by FLASH irradiation per Gy were (2.78±0.03) and (1.85±0.17) times higher than those of conventional irradiation, respectively. Conclusions:FLASH irradiation attenuated radiation-induced DNA damage since a low production yield of free radical in comparison with conventional irradiation, and hence the FLASH effect was correlated with oxygen content.

ABSTRACT

Objective:To investigate the prognostic value of metabolic parameters of 18F-fluorodeoxyglucose ( 18F-FDG) positron emission computed tomography/computed tomography(PET/CT) in advanced non-small cell lung cancer(NSCLC) treated with first-line immune checkpoint inhibitor (ICI) combined with chemotherapy. Methods:A retrospective study was conducted to evaluate patients with advanced NSCLC who underwent baseline PET/CT before treatment at the Affiliated Cancer Hospital of Zhengzhou University from 2019 to 2021. Receiver operating characteristic (ROC) curve analysis was used to determine the cut-offs for metabolic parameters of PET/CT, including total metabolic tumor volume (TMTV), total lesion glycolysis (TLG), and maximum standard uptake value (SUV max). Kaplan-Meier method, Log-rank test, and Cox regression model were used to calculate the overall survival (OS) and the progression-free survival(PFS). Results:A total of 44 patients were enrolled. Univariate analysis showed that the factors influencing PFS were TMTV and the number of metastatic sites ( χ2=4.19, 11.28, P<0.05) and the factors influencing OS were TMTV and TLG ( χ2=14.96, 6.05, P<0.05). Multivariate analysis suggested that number of metastatic sites was an independent prognostic marker for PFS ( P=0.011) and TMTV was an independent prognostic marker for OS ( P=0.038). Conclusions:TMTV is a prognostic indicator of OS while the number of metastatic sites is a prognostic indicator of PFS in advanced NSCLC patients who received first-line ICI combined with chemotherapy, but further prospective studies are needed.

ABSTRACT

OBJECTIVE@#To assess the effectiveness of Jiuwei Zhuhuang Powder (JWZH), a Tibetan patent medicine in treating upper respiratory tract infection (URTI) associated cough in children.@*METHODS@#The study was a multicenter, randomized, open-label, controlled trial. A total of 142 children aged 2 to 14 years old, with URTI-associated cough within 48 h of onset, were randomly assigned to two groups at a 1:1 ratio by computer-generated randomization sequence. Children were treated with JWZH (1 to 1.5 g, twice to thrice daily) in the treatment group or conventional treatment (Pediatric Paracetamol, Artificial Cow-bezoar and Chlorphenamine Maleate Granules, 0.25 to 1 g, thrice daily) in the control group for 5 days. The primary endpoints were the time to cough resolution and 4-day cough resolution rate. The secondary endpoints were the daily improvement in symptom scores and cough resolution rate during the study period.@*RESULTS@#A total of 138 children were included in the intention-to-treat analysis, with 71 cases in the treatment group and 67 cases in the control group. Compared with the conventional treatment, the children receiving JWZH had a shorter time to cough resolution [hazard ratio, 2.10; 95% confidence interval (CI), 1.29-3.40; P=0.003]. The median time to cough resolution for children receiving JWZH was shorter than that of the conventional treatment (2 days vs. 3 days; P<0.001). The 4-day cough resolution rate in the JWZH group was higher than that of the control group (94.4% vs. 74.6%; risk difference: 19.8%, 95% CI: 8.1%-31.5%; relative risk: 1.265, 95% CI: 1.088-1.470; P=0.001). There were no statistically significant differences in the improvement of other symptoms caused by URTI (P>0.05). Adverse events was reported in 5.6% (4/71) and 4.5% (3/67) in participants of JWZH and PPACCM groups (P>0.05), respectively, which were all mild and resolved without treatment.@*CONCLUSION@#JWZH seemed to be a safe and effective therapy for URTI-associated cough in children.

ABSTRACT

OBJECTIVE@#To observe the effect of thumb-tack needles based on "Biaoben acupoint compatibility" on sequela symptoms, mental state and pulmonary ventilation function in patients with coronavirus disease 2019 (COVID-19) during recovery period.@*METHODS@#Fifty cases of COVID-19 during recovery period were randomly divided into an observation group and a control group, 25 cases in each group. The patients in the observation group were treated with thumb-tack needles at Guanyuan (CV 4), Zusanli (ST 36) and Taiyuan (LU 9). The patients in the control group were treated with sham thumb-tack needles at identical acupoints as the observation group. The treatment in the two groups was given once a day, 7-day treatment was taken as a course of treatment, and totally two courses of treatment were given. The TCM symptom score, Hamilton anxiety scale (HAMA) score, Hamilton depression scale (HAMD) score, pulmonary function (forced vital capacity [FVC], forced expiratory volume in the first second [FEV1], peak expiratory flow [PEF]), the severity of pulmonary ventilation dysfunction and pulmonary imaging changes in the two groups were compared before and after treatment.@*RESULTS@#Compared before treatment, the total scores and each item scores of TCM symptom scale, HAMA scores and HAMD scores in the two groups were reduced after treatment (P<0.05). Except for the symptom scores of dry throat and dry stool, the total score and each item score of TCM symptom scale, HAMA score and HAMD score in the observation group were lower than those in the control group (P<0.05). Compared before treatment, FVC, FEV1 and PEF in the two groups were increased after treatment (P<0.05), and those in the observation group were higher than the control group (P<0.05). The severity of pulmonary ventilation dysfunction in the two groups was reduced after treatment (P<0.05), and the severity in the observation group was better than that in the control group (P<0.05). After treatment, the lung shadow area in the two groups was decreased (P<0.05), and that in the observation group was smaller than the control group (P<0.05). The improvement of imaging change in the observation group was better than that in the control group (P<0.05).@*CONCLUSION@#The thumb-tack needles based on "Biaoben acupoint compatibility" could significantly reduce the sequela symptoms, anxiety and depression in patients with COVID-19 during recovery stage, and improve the pulmonary ventilation function.

ABSTRACT

ObjectiveTo retrospectively analyze the clinical data of 52 patients with coronavirus disease-2019 (COVID-19) and explore the clinical efficacy of modified Sanxiaoyin on mild/moderate COVID-19 patients. MethodThe propensity score matching method was used to collect the clinical data of mild or moderate COVID-19 patients enrolled in the designated hospital of the Second Hospital of Jingzhou from December 2019 to May 2020. A total of 26 eligible patients who were treated with modified Sanxiaoyin were included in the observation group, and the 26 patients treated with conventional method were the regarded as the control. The disappearance of clinical symptoms, disappearance time of main symptoms, efficacy on traditional Chinese medicine (TCM) symptoms, hospitalization duration, laboratory test indicators, and CT imaging changes in the two groups were compared. ResultThe general data in the two groups were insignificantly different and thus they were comparable. After 7 days of treatment, the disappearance rate of fever, cough, fatigue, dry throat, anorexia, poor mental state, and poor sleep quality in the observation group was higher than that in the control group (P<0.05), and the difference in the disappearance rate of expectoration and chest distress was insignificant. For the cases with the disappearance of symptoms, the main symptoms (fever, cough, fatigue, dry throat, anorexia, chest distress) disappeared earlier in the observation group than in the control group (P<0.01). After 7 days of treatment, the scores of the TCM symptom scale of both groups decreased (P<0.01), and the decrease of the observation group was larger that of the control group (P<0.01). All patients in the two groups were cured and discharged. The average hospitalization duration in the observation group [(12.79±2.68) d] was shorter than that in the control group [(15.27±3.11) d] (P<0.01). The effective rate in the observation group (92.31%, 24/26) was higher than that in the control group (76.92%, 20/26) . After 7 days of treatment, the lymphocyte (LYM) count increased (P<0.05), and white blood cell (WBC) count and neutrophil (NEUT) count decreased insignificantly in the two groups. Moreover, levels of C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and procalcitonin (PCT) reduced in the two groups after treatment (P<0.01) and the reduction in the observation group was larger than that in the control group (P<0.01). Through 7 days of treatment, the total effective rate on pulmonary shadow in the observation group (90.00%, 18/20) was higher than that in the control group (77.27%, 17/22) (P>0.05) and the improvement of lung shadow in the observation group was better than that in the control group (P<0.01). ConclusionModified Sanxiaoyin can significantly alleviate fever, cough, fatigue, anorexia, chest distress, poor sleep quality, and other symptoms of patients with mild or moderate COVID-19, improve biochemical indicators, and promote the recovery of lung function. This paper provides clinical evidence for the application of modified Sanxiaoyin in the treatment of mild or moderate COVID-19.
