ABSTRACT

As an indicator that measures the degree of implementation of intervention measures during the implementation process, fidelity could be used for monitoring and quality evaluation of the completion degree of intervention measures, and plays an important role in improving the degree of intervention implementation and clarifying the factors that affect intervention implementation. This article aims to introduce the connotation and significance, measurement, control, and current application status of fidelity, as well as the current application status of fidelity in acupuncture-moxibustion clinical research and its inspiration for future research. Meanwhile, based on the existing evaluation tool development methods of fidelity and the characteristics of acupuncture-moxibustion clinical research, a preliminary fidelity evaluation framework is proposed. Introducing fidelity into acupuncture-moxibustion clinical research could improve the implementation quality and compliance of acupuncture-moxibustion in clinical research, increase the credibility and effectiveness of clinical research results, and promote the transformation of acupuncture-moxibustion experience into easily learnable and promotable treatment plans.

ABSTRACT

Uncontrolled and persistent inflammation is closely related to numerous acute and chronic diseases. However, effective targeting delivery systems remain to be developed for precision therapy of inflammatory diseases. Herein we report a novel strategy for engineering inflammation-accumulation nanoparticles via phenolic functionalization. Different phenol-functionalized nanoparticles were first developed, which can undergo in situ aggregation upon triggering by the inflammatory/oxidative microenvironment. Phenolic compound-decorated poly (lactide-co-glycolide) nanoparticles, in particular tyramine (Tyr)-coated nanoparticles, showed significantly enhanced accumulation at inflammatory sites in mouse models of colitis, acute liver injury, and acute lung injury, mainly resulting from in situ cross-linking and tissue anchoring of nanoparticles triggered by local myeloperoxidase and reactive oxygen species. By combining a cyclodextrin-derived bioactive material with Tyr decoration, a multifunctional nanotherapy (TTN) was further developed, which displayed enhanced cellular uptake, anti-inflammatory activities, and inflammatory tissue accumulation, thereby affording amplified therapeutic effects in mice with colitis or acute liver injury. Moreover, TTN can serve as a bioactive and inflammation-targeting nanoplatform for site-specifically delivering a therapeutic peptide to the inflamed colon post oral administration, leading to considerably potentiated in vivo efficacies. Preliminary studies also revealed good safety of orally delivered TTN. Consequently, Tyr-based functionalization is promising for inflammation targeting amplification and therapeutic potentiation of nanotherapies.

ABSTRACT

OBJECTIVE@#To assess the efficacy and safety of Guanxin Danshen Dripping Pills (GXDS) in the treatment of depression or anxiety in patients with coronary heart disease (CHD) after percutaneous coronary intervention (PCI).@*METHODS@#From September 2017 to June 2019, 200 CHD patients after PCI with depression and anxiety were included and randomly divided into GXDS (100 cases) and placebo control groups (100 cases) by block randomization and a random number table. Patients in the GXDS and control groups were given GXDS and placebo, respectively, 0.4 g each time, 3 times daily for 12 weeks. The primary outcomes were scores of Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Scale (GAD-7) and the Seattle Angina Pectoris Scale (SAQ). The secondary outcomes included 12 Health Survey Summary Form (SF-12) scores and the first onset time and incidence of major adverse cardiovascular events (MACEs). Other indices including blood pressure, blood lipids, microcirculation and inflammatory-related indices, etc. were monitored at baseline, week 4, and week 12.@*RESULTS@#In the full analysis set (200 cases), after treatment, the PHQ-9 and GAD-7 scores in the GXDS group were considerably lower than those in the control group (P<0.05). Compared with the baseline, the total PHQ-9 scores of the experimental and control groups decreased by 3.97 and 1.18, respectively. The corrected mean difference between the two groups was -2.78 (95% CI: -3.47, -2.10; P<0.001). The total GAD-7 score in the GXDS group decreased by 3.48% compared with the baseline level, while that of the placebo group decreased by 1.13%. The corrected mean difference between the two groups was -2.35 (95% CI: -2.95, -1.76; P<0.001). The degree of improvement in SAQ score, SF-12 score, endothelin and high-sensitive C-reactive protein levels in the GXDS group were substantially superior than those in the placebo group, and the differences between the two groups were statistically significant (P<0.05). Similar results were obtained in the per protocol population analysis of 177 patients. Three cases of MACES were reported in this study (1 in the GXDS group and 2 in the placebo group), and no serious adverse events occurred.@*CONCLUSIONS@#GXDS can significantly alleviate depression and anxiety, relieve symptoms of angina, and improve quality of life in patients with CHD after PCI.

ABSTRACT

Objective: To investigate the clinical characteristics of children with allergic diseases suffering from SARS-CoV-2 Omicron variant strains. Methods: This was a cross-sectional study. A total of 43 pediatric patients with allergic diseases infected by SARS-CoV-2 from April 25, 2022 to June 8, 2022 in Shanghai Jiao Tong University School of Medicine were selected as the allergic disease group, while 114 cases without underlying diseases and 16 cases with other underlying diseases were selected as control groups diagnosed at the same period. Clinical data including clinical features, laboratory tests, duration of hospitalization, and the time to negative turn of novel coronavirus nucleic acid were collected and analysed. Kruskal-Wallis H test, chi-square test or Fisher exact test were used for comparison among three groups. Results: Among the 43 patients with allergic diseases, 28 were males and 15 were females, with an age of 4.4 (2.1, 8.2) years on admission, including 32 mild cases and 11 common cases. The allergic disease group included 20 cases (46.5%) of atopic dermatitis and eczema, followed by 14 cases (32.6%) of rhinitis, 8 cases (18.6%) of food allergies, 7 cases (16.3%) of asthma, 4 cases (9.3%) of allergic conjunctivitis and 2 cases (4.7%) of drug allergy. Among the 114 cases without underlying diseases, 57 were males and 57 were females, with an age of 2.8 (1.2, 5.6) years on admission, including 93 mild cases and 21 common cases. Among the 16 cases with other underlying diseases, 9 were males and 7 were females, with an age of 3.0 (2.6, 10.8) years on admission, including 13 cases mild and 3 cases common cases. Children with allergic diseases had higher frequency of sore throat and vomiting than those without underlying diseases (10 cases (23.3%) vs.9 cases (7.9%), 14 cases (32.6%) vs. 11 cases (9.6%), χ²=6.93, 12.24, both P<0.05). The lymphocyte count of patients with allergic disease was lower than those without underlying disease (1.1 (0.7,1.7)×109 vs. 1.6 (1.1,2.7)×109/L, H=-28.00,P=0.005). There were no significant differences in age, gender, typing of SARS-CoV-2, the duration of hospitalization, cycle threshold values of SARS-CoV-2 and the time to negative turn of novel coronavirus nucleic acid among the three groups (all P>0.05). Conclusions: Children with allergic diseases may suffer from sore throat and vomiting more frequently when infected with SARS-CoV-2 Omicron variant. The combination of allergic diseases hardly influenced the disease course of SARS-CoV-2 in children.

ABSTRACT

Objective: Compare and analyze the results of the domestic Lanyi AH600 glycated hemoglobin analyzer and other different detection systems to understand the comparability of the detection results of different detectors, and establish the best cut point of Lanyi AH600 determination of haemoglobin A1c (HbA1c) in the diagnosis of diabetes. Methods: Multi center cohort study was adopted. The clinical laboratory departments of 18 medical institutions independently collected test samples from their respective hospitals from March to April 2022, and independently completed comparative analysis of the evaluated instrument (Lanyi AH600) and the reference instrument HbA1c. The reference instruments include four different brands of glycosylated hemoglobin meters, including Arkray, Bio-Rad, DOSOH, and Huizhong. Scatter plot was used to calculate the correlation between the results of different detection systems, and the regression equation was calculated. The consistency analysis between the results of different detection systems was evaluated by Bland Altman method. Consistency judgment principles: (1) When the 95% limits of agreement (95% LoA) of the measurement difference was within 0.4% HbA1c and the measurement score was≥80 points, the comparison consistency was good; (2) When the measurement difference of 95% LoA exceeded 0.4% HbA1c, and the measurement score was≥80 points, the comparison consistency was relatively good; (3) The measurement score was less than 80 points, the comparison consistency was poor. The difference between the results of different detection systems was tested by paired sample T test or Wilcoxon paired sign rank sum test; The best cut-off point of diabetes was analyzed by receiver operating characteristic curve (ROC). Results: The correlation coefficient R2 of results between Lanyi AH600 and the reference instrument in 16 hospitals is≥0.99; The Bland Altman consistency analysis showed that the difference of 95% LoA in Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180) was -0.486%-0.325%, and the measurement score was 94.6 points (473/500); The difference of 95% LoA in the Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant II) was -0.727%-0.612%, and the measurement score was 89.8 points; The difference of 95% LoA in the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT) was -0.231%-0.461%, and the measurement score was 96.6 points; The difference of 95% LoA in the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT) was -0.469%-0.479%, and the measurement score was 91.9 points. The other 14 hospitals, Lanyi AH600, were compared with 4 reference instrument brands, the difference of 95% LoA was less than 0.4% HbA1c, and the scores were all greater than 95 points. The results of paired sample T test or Wilcoxon paired sign rank sum test showed that there was no statistically significant difference between Lanyi AH600 and the reference instrument Arkray HA8180 (Z=1.665,P=0.096), with no statistical difference. The mean difference between the measured values of the two instruments was 0.004%. The comparison data of Lanyi AH600 and the reference instrument of all other institutions had significant differences (all P<0.001), however, it was necessary to consider whether it was within the clinical acceptable range in combination with the results of the Bland-Altman consistency analysis. The ROC curve of HbA1c detected by Lanyi AH600 in 985 patients with diabetes and 3 423 patients with non-diabetes was analyzed, the area under curve (AUC) was 0.877, the standard error was 0.007, and the 95% confidence interval 95%CI was (0.864, 0.891), which was statistically significant (P<0.001). The maximum value of Youden index was 0.634, and the corresponding HbA1c cut point was 6.235%. The sensitivity and specificity of diabetes diagnosis were 76.2% and 87.2%, respectively. Conclusion: Among the hospitals and instruments currently included in this study, among these four hospitals included Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180), Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant Ⅱ), the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT), and the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT), the comparison between Lanyi AH600 and the reference instruments showed relatively good consistency, while the other 14 hospitals involved four different brands of reference instruments: Arkray, Bio-Rad, DOSOH, and Huizhong, Lanyi AH600 had good consistency with its comparison. The best cut point of the domestic Lanyi AH600 for detecting HbA1c in the diagnosis of diabetes is 6.235%.

ABSTRACT

Objective: To analyze the drug resistance and multilocus sequence typing of five types of diarrheagenic Escherichia coli (DEC) isolated from diarrhea outpatients of diarrhea comprehensive monitoring designated hospital in Qingpu District, Shanghai from 2015 to 2019. Methods: From January 2015 to December 2019, five types of DEC, isolated and identified from diarrhea outpatient cases' anal swabs of the Qingpu branch of Zhongshan Hospital were collected to determine the minimal inhibitory concentration by using the micro broth dilution susceptibility test. The strains, resistant to the third-generation cephalosporins or carbapenems, or producing ESBLs, were selected based on the results of sensitivity tests and determined by WGS. The MLST typing of DEC was analyzed based on the WGS technology and the minimum spanning tree was constructed by BioNumerics 7.6 software to analyze the local dominant flora. Results: A total of 513 strains of DEC were detected and isolated from 4 494 anal swabs, with a detection rate of 11.42%. About 500 strains were tested for drug sensitivity to nine antibiotics in four classes, including 330 strains of enterotoxigenic E.coli (ETEC), 72 strains of enteroaggregative E.coli (EAEC), 95 strains of enteropathogenic E.coli (EPEC), 1 strain of enterohemorrhagic E.coli (EHEC), and 2 strains of enteroinvasive E.coli (EIEC). From 2015 to 2019, the resistance rate of cefotaxime-clavulanic acid was significantly different (P<0.05). The resistance rate of virulence types of DEC to nalixic acid was significantly different (P<0.05). About 71 strains of DEC were determined by WGS, and 77 drug-resistant genes were detected. Strains were classified into 32 ST subtypes, with the dominant genotypes being ST-1491 (29.6%, 21/71) and ST-10 Complex (23.9%, 17/71). All ST-1491 produced ESBLs, which were blaCTX-M gene mutant strains. The dominant type of ST-10 complex was ST-218 (35.3%, 6/17). In addition, 8 strains of EAEC, 14 strains of EPEC and 49 strains of ETEC were classified into 7, 14 and 18 ST subtypes, respectively. Conclusion: The drug resistance of DEC strains from the diarrhea outpatient case of Qingpu District is serious. The ST types of EAEC and EPEC are highly polymorphic. The dominant ST types of DEC are basically consistent with the common genotypes in southeast China.

ABSTRACT

Objective Tto analyze the spatial distribution and characteristics of the national AIDS/HIV epidemics from 2009 to 2020 to discover its distribution, aggregation, and hot spots, and provide corresponding suggestions for AIDS prevention and control. Methods Spatial autocorrelation analysis, hot spot analysis, and Kriging interpolation prediction were used to describe, analyze, and predicting the spatial distribution of AIDS epidemics across the country. Results The national AIDS incidence and mortality rate increased yearly, but the growth rate shows a downward tendency with uneven spatial distribution,focusing on the southwest and northwest regions; the average annual incidence rate of AIDS ( Moran's I> 0, P 0, P “high-high” clusters of AIDS incidence; Sichuan, Yunnan, Guangxi,Hunan,Xinjiang and Guizhou were the areas with “high-high” clusters of average annual mortality. The “hot spot” areas were mainly concentrated in the southwestern part of China, and the “cold spot” areas were mainly concentrated in the eastern coastal and northern parts of China; Kriging interpolation predicted that Xinjiang would be the new hot spot area for future epidemics. Conclusion The spatial distribution of AIDS in China is uneven, showing spatial aggregation, hot spots and cold spots coexist, and the high-risk areas will continue to expand in the future.So the prevention and control work should be carried out in a targeted and localized manner.

ABSTRACT

Objective: To investigate the quality of life and associated factors in patients with coronary heart disease (CHD) in China. Methods: A cross-sectional study of 25 provinces and cities in China was performed from June to September 2020. A questionnaire was used to collect the socio-demographic and clinical information of patients with CHD, while the European Five-dimensional Quality of Life Scale (EQ-5D) was used to assess the quality of life. Multiple linear regression model was performed to analyze the associated factors. Results: The median age of the 1 075 responders was 60 (52, 67) years, and 797 (74.1%) were men. The EQ-5D and EQ-VAS indices were 0.7 (0.5, 0.8) and 60.0 (40.0, 80.0). Among the five dimensions in the quality of life scale, the frequency of anxiety/depression was the highest (59.8%), while problems in self-care was the lowest (35.8%). In the multiple linear regression model, female, increasing age, obesity, comorbidity(ies), anxiety/depression, social media channels, and receiving the CABG therapy were associated with the lower EQ-5D index (all P<0.05). In addition, increasing age, obesity, comorbidity (ies), depression, anxiety and depression, social media channels, and receiving the CABG therapy were associated with lower EQ-VAS index (all P<0.05). Conclusion: Over half of the patients with CHD in China have a low quality of life, which is related to gender, age, obesity, treatment pathway, the presence or absence of comorbidity (ies), and psychological state. In addition to managing the adverse effects of traditional socio-demographic factors on the quality of life, clinical practices should pay attention to the psychological state of patients. Moreover, establishing a WeChat group for doctor-patient communication could improve the quality of life of CHD patients.

ABSTRACT

Objective:To investigate the efficacy of mosapride versus domperidone in the treatment of functional dyspepsia and its effects on gastric motility indexes and gastrointestinal hormone levels. Methods:Ninety-four patients with functional dyspepsia who received treatment in Huzhou Linghu People's Hospital between May 2019 and May 2021 were included in this study. They were randomly assigned to undergo treatment with either domperidone (control group, n = 47) or mosapride (study group, n = 47). Efficacy was compared between the two groups. Results:Total response rate in the study group was significantly higher than that in the control group ( χ2 = 5.04, P = 0.025). After medication, motilin, plasma leptin and corticotropin-releasing hormone in the study group were (184.22 ± 25.36) μg/mL, (18.57 ± 2.44) μg/L, (7.21 ± 1.14) pg/mL, respectively, which were superior to those in the control group [(111.25 ± 21.00) μg/mL, (15.41 ± 2.28) μg/L, (9.02 ± 1.32) μg/mL, t = 15.19, 6.48, 16.23, P < 0.001, < 0.001, < 0.001]. After medication, cholecystokinin, somatostatin, vasoactive intestinal peptide and gastrin levels in the study group were (45.36 ± 5.12) ng/L, (5.48 ± 1.25) ng/L, (86.35 ± 12.11) pg/mL, and (105.24 ± 12.05) ng/L, respectively, which were significantly superior to those in the control group [(50.21 ± 6.18) ng/L, (7.01 ± 0.98) ng/L, (98.75 ± 14.18) pg/mL and (97.35 ± 11.48) ng/L, t = 4.14, 6.60, 4.55, 3.25, P < 0.001, < 0.001, < 0.001, < 0.002]. The recurrence rate in the study group was significantly lower than that in the control group (2.13% vs. 27.66%, χ2 = 4.66, P = 0.031). The incidence of adverse reactions in the study group was significantly lower than that in the control group (14.89% vs. 34.04%, χ2 = 10.80; P = 0.001). Conclusion:Mosapride has a better therapeutic effect on functional dyspepsia, exhibits a greater effect on improving gastric motility indexes and gastrointestinal hormone levels, and leads to a lower incidence of recurred functional dyspepsia than domperidone. Therefore, mosapride for treatment of functional dyspepsia deserves clinical promotion.

ABSTRACT

Objective:To investigate the clinical efficacy of neuroendoscopic hematoma removal versus soft channel drainage in the treatment of chronic subdural hematoma (CSDH) and their effects on neurological function and quality of life. Methods:The clinical data of 97 patients with CSDH who received treatment between February 2018 and December 2019 were retrospectively analyzed. These patients were divided into group A ( n = 48, soft channel drainage) and group B ( n = 49, neuroendoscopic hematoma removal) according to different surgical methods. Clinical indicators, neurological function, quality of life, and incidence of complications were compared between groups A and B. Results:Operative time, length of hospital stay, and latency to hematoma disappearance in group B were (31.3 ± 2.18) minutes, (8.16 ± 1.32) days, (7.45 ± 1.49) days, which were significantly shorter than those in group A [(35.15 ± 4.32) minutes, (13.18 ± 1.56) days, (11.32 ± 1.88) days, t = 5.53, 17.12, 11.25, all P < 0.001]. At 3 months after surgery, the score of each dimension of SF-36 in each group was increased. The scores of physiological functioning, bodily pain, mental health, general health perceptions, social role functioning, vitality, role limitations due to emotional health, role limitations due to physical health in group B were (84.94 ± 7.25) points, (84.02 ± 6.29) points, (82.85 ± 8.16) points, (84.36 ± 9.15) points, (83.51 ± 10.39) points, (82.68 ± 8.36) points, (84.93 ± 10.15) points, (86.12 ± 9.13) points, which were significantly higher than those in group A [(62.68 ± 5.47) points, (71.39 ± 7.42) points, (69.51 ± 6.39) points, (72.68 ± 7.36) points, (72.81 ± 8.15) points, (73.12 ± 10.13) points, (77.91 ± 9.52) points, (75.32 ± 7.51) points, t = 19.82, 18.34, 19.75, 16.71, 17.94, 20.57, 18.22, 16.44, all P < 0.001]. At 7 days after surgery, neurotrophic factor, neuron specific enolase, hydrogen sulfide and S100B protein levels in group B were (42.53 ± 6.09) μg/L, (6.52 ± 2.79) μg/L, (203.17 ± 15.03) μmol/L, (0.25 ± 0.05) μg/L, respectively, which were significantly lower than those in group A [(67.38 ± 7.42) μg/L, (9.18 ± 2.27) μg/L, (242.79 ± 14.08) μmol/L, (0.36 ± 0.07) μg/L, t = 17.94, 5.12, 13.33, 8.86, all P < 0.001]. There was no significant difference in the incidence of complications between group B and group A [8.16% (4/49) vs. 18.75% (9/48), χ2 = 2.22, P = 0.136]. Conclusion:Compared with soft channel drainage, neuroendoscopic hematoma removal can better improve clinical indicators, neurological function, and quality of life in patients with CSDH, and is highly safe Neuroendoscopic hematoma removal is of certain clinical application value and innovation.

ABSTRACT

Objective:To improve training quality and to standardize the assessment procedures of radiology standardized residency training by analyzing the results of the clinical skills completion assessment for radiology standardized residency training in Liaoning Province in 2020.Methods:Totally 186 trainees participated the assessment with 6 exams in 3 days, including "Man-Machine interview" and "oral interview". Reliability and validity of the test were analyzed first. The accuracy were compared among the three parts of radiology, ultrasound and nuclear medicine, and also among the three portions of imaging description, diagnosis and relative question. Trainees of different type, gender and from different regions were further compared respectively. Scores of different examiners were also compared. SPSS 20.0 software was used for t-test and one-way ANOVA. Results:The Cronbach's α coefficient ranged from 0.65 to 0.87, and KMO values were nearly or higher than 0.7. Scores of both "Man-Machine interview" and "oral interview" parts were better relative to the total scores (relativity coefficient 0.698-0.969). The accuracy of radiology was relatively higher and more stable (nearly 80%), nuclear medicine had the lowest accuracy (nearly 50%), and that of ultrasound fluctuated obviously (56.2%-88.8%). The accuracy was the highest for imaging description, followed by diagnosis, and the lowest for relative question portion. There were significant differences between male and female residents in "Man-Machine interview" portion ( P=0.028), while there was not in "oral interview" ( P=0.050). There were significantly statistical differences in trainees' scores between different regions ( P=0.009 for "Man-Machine interview" and P<0.001 for "oral interview"). Trainees from Shenyang and Dalian got almost the same scores, which were significantly higher than those from other cities. Trainees with master's degree were scored higher than others trainees that were not (all P<0.001). Significant score differences were found between the two examiners in only one examiner group (1/18) ( P=0.011). Conclusion:By the analysis of test results, we find the shortage of both training and assessment process, which is beneficial to adjusting the training process, improving the training quality, and promoting the further standardization and development of the assessment system of radiology standardized residency training.

ABSTRACT

Objective: To explore the occupational hazards caused by three kinds of welding operations, and to provide data support for individual protection. Methods: In October 2020, the welding fumes, metal elements and welding arc generated by three welding operations of argon gas shielded welding (JS80 welding wire) , manual welding (ZS60A welding rod) and carbon dioxide shielded welding (907A flux cored wire) were collected and measured in the welding laboratory. The samples were analyze and compare in the laboratory, and the differences of the occupational hazard factors of the three welding operations were judged. Results: The concentration of welding fume produced by carbon dioxide shielded welding, manual welding (ZS60A electrode) , and argon gas shielded welding (JS80 welding wires) were 6.80 mg/m(3), 6.17 mg/m(3), and 3.13 mg/m(3), respectively. The effective irradiance of the welding arc outside the welding mask from high to low is manual welding (ZS60A electrode) , carbon dioxide shielded welding (907A flux-cored welding wire) , and argon shielded welding (JS80 welding wire) , respectively 1 010.7, 740.9, 589.5 μW/cm(2). The long-wave ultraviolet UVA intensity generated by argon shielded welding (JS80 welding wire) is the largest, which is 1 500 μW/cm(2). The content of Mn in the three welding operations is the highest, and JS80 welding wire has the highest Mn content of 128493.2 mg/kg. 907A flux cored wire has the highest Ti content, which is 24355.5mg/kg. The electrode ZS60A has the highest Cu content, which is 24422.12 mg/kg. Conclusion: The intensity of occupational hazards is different in the three kinds of welding operations, so the methods of personal protective equipment, field exposure assessment and health monitoring should be more targeted.

ABSTRACT

Objective:To compare the therapeutic effect of one-stage versus two-stage percutaneous transhepatic biliary fistulation lithotripsy in treatment of complex hepatolithiasis.Methods:A retrospective study was conducted on 145 patients with complex hepatolithiasis who were treated at the First Affiliated Hospital of Guangzhou Medical University between September 2013 and June 2018. There were 60 males and 85 females, aged 21 to 91 (56.5±14.1) years. According to the method of fistula establishment, patients were divided into the percutaneous transhepatic one-step biliary fistulation (PTOBF) group ( n=94) or the two-stage percutaneous transhepatic choledochoscopic lithotripsy (PTCSL) group ( n=51). The success rates of one-time puncture and fistula dilation, operation time of lithotripsy, operative conversion rate (PTCSL was converted to laparotomy and laparoscopic surgery), postoperative complications (including catheter dislodgement), residual stone rates and stone recurrence rates were compared between groups. Results:In the PTOBF group, operation time (105.8±43.6) min, success rate of one puncture 73.4% (69/94), and success rate of one fistula dilation 93.6% (88/94), the rate of operative conversion 0. All these results were significantly better than the corresponding results of the two-stage PTCSL group of (130.0±70.0) min, 54.9% (28/51), 68.6% (35/51), and 13.7%(7/51) respectively (all P<0.05). There were no significant differences in stone residual rate [17.0%(16/94) vs. 15.7% (8/51)] and stone recurrence rate [14.9%(14/94) vs. 17.6% (9/51)] between groups (both P>0.05). The postoperative complications rate was 7.4%(7/94) in PTOBF group, which was 39.2% (20/51) in two-stage PTCSL group (χ 2=22.02, P<0.001). The catheter dislodgement rate of PTOBF group was 2.1% (2/94), lower than that of two-stage PTCSL group 27.4% (14/51), the difference was statistically significant (χ 2=21.59, P<0.001). Conclusion:One-stage PTOBF and two-stage PTCSL were both safe and effective in treatment of complex hepatolithiasis. However, PTOBF had shorter operative times, lower catheter dislodgement and operative conversion rates than PTCSL.

ABSTRACT

Objective: To investigate the long-term efficacy and safety of left cardiac sympathetic denervation(LCSD) for long QT syndrome(LQTS) patients with either recurrence on drug therapy intolerance/refusal. Methods: This study was a retrospective cohort study. The cases selected from 193 patients with LQTS who were enrolled in the Chinese Channelopathy Registry Study from November 1999 to November 2012. This study selected 28 LQTS patients with either recurrence on drug therapy intolerance/refusal and underwent LCSD surgery in the Peking University People's Hospital or Beijing Tongren Hospital. The patients were allocated into 3 groups: high-risk group(n=13, baseline QTc ≥550 ms or symptomatic in the first year of life or highly malignant genetics); intermediate-risk group(n=10, 500 ms≤baseline QTc<550 ms, symptomatic after the first year and without highly malignant genetics); low-risk group(n=5, baseline QTc<500 ms, symptomatic after the first year and without highly malignant genetics). LCSD was performed with the traditional supraclavicular approach or video assisted thoracoscopic surgery (VATS). Patients were regularly followed up until 20 years after the surgery. Data were collected before and 1 year after surgery and at the last follow-up. Patients' electrocardiograph(ECG), cardiac events and surgery-related complications were recorded. Kaplan-Meier survival analysis was used to determine the cardiac event-free survival based on different risk stratification and genotypes. Results: A total of 28 LQTS patients, aged 20.5 (15.0, 37.5) and underwent LCSD surgery, were enrolled in this study, including 23(82.1%) women. There were 11(39.3%) patients treated with traditional approach while 17(60.7%) with VATS-LCSD. There were 19(67.9%) patients had positive genetic test results, including 4 LQT1, 12 LQT2, 1 LQT1/LQT2 mixed type, and 2 Jervell-Lange-Nielsen (JLN) syndrome. The median follow-up period was 189.3(138.7, 204.9) months. The dropout rate was 10.7%(3/28) while 3 patients in the intermediate-risk group were lost to follow-up. Horner syndrome occurred in 1 patient (in the high-risk group). Sudden cardiac deaths were observed in 3 (12.0%) patients (all in the high-risk group), and 12 patients (48.0%) had syncope recurrences (2 in low-risk group, 3 in intermediate-risk group and 7 in high-risk group). A significant reduction in the mean yearly episodes of cardiac events was observed, from (3.5±3.3) before LCSD to(0.2±0.1) at one year after LCSD and (0.5±0.8) at last follow up(P<0.001). The mean QTc was shortened from (545.7±51.2)ms before the surgery to (489.0±40.1)ms at the last follow-up (P<0.001). Among the 20 patients with basic QTc ≥500 ms and completing the follow-up, the QTc intervals of 11(55.0%) patients were shortened to below 500 ms. The event free survival rates for any cardiac events after LCSD decreased sequentially in the low-, intermediate- and high-risk groups, and the difference was statistically significant (χ²=7.24, log-rank P=0.026). No difference was found in the event free survival rates among LQT1, LQT2 and undefined gene patients (χ²=5.20, log-rank P>0.05). Conclusions: LCSD surgery can reduce the incidence of cardiac events and shorten the QTc interval in patients with LQTS after the long-term follow-up. LCSD surgery is effective and safe for patients with LQTS ineffective or intolerant to drug therapy. However, high-risk patients are still at a high risk of sudden death after surgery and should be actively monitored and protected by combined therapies.

ABSTRACT

ObjectiveTo collect and screen records concerning the spleen and stomach diseases and syndromes in ancient books of traditional Chinese medicine (TCM) using an automated framework and to systematically explore the concept evolution of spleen and stomach diseases and syndromes using the visualization method. MethodA total of 1 224 kinds of ancient book data in the Ancient Books of Traditional Chinese Medicine Database (V2.1) were analyzed using the automated testing tool Selenium WebDriver with the Python 3.8 programming language and the etree library of Lxml for automatic collection and statistics of the "book title" "author" "classification" "dynasty" "completion time", and "informative abstract". After being checked and collated, the collected data were visually analyzed with Tableau (V2020.1.3) for figuring out the concept evolution of spleen and stomach diseases and syndromes in the past dynasties from the perspectives of symptoms and signs, etiology and pathogenesis, principle-method-recipe-medicinal, and prognosis. ResultA total of 7 203 clauses were automatically collected from 989 ancient books. It was found that in the pre-Qin period, there were few ancient books related to the spleen and stomach diseases and syndromes, and the understandings were confined to the superficial symptoms or signs and the basic etiology and pathogenesis. From the Han to Sui and Tang dynasties, the related concepts gradually increased and the descriptions about the manifestations are more detailed than those in previous dynasties. The etiology, diagnosis, and treatment system of the spleen and stomach diseases and syndromes were further perfected. In the Song, Jin, and Yuan dynasties, such concepts as independent signs,symptoms, as well as nature and location of spleen and stomach diseases and syndromes were enriched. In the Ming and Qing dynasties, a TCM syndrome differentiation and treatment system for spleen and stomach diseases and syndromes was formed, and the related concepts were gradually simplified and unified. ConclusionThe concepts of spleen and stomach diseases and syndromes have undergone an evolution from simplicity to complexity and then back to simplicity. There are numerous ancient books discussing the concepts of spleen and stomach diseases and syndromes, exhibiting a fluctuating yet rising trend with time. The automated framework enables the construction of a lightweight database of spleen and stomach diseases and syndromes. Based on data visualization, the concept evolution of the spleen and stomach diseases and syndromes from ancient times to the present has been efficiently uncovered, which is conducive to tracing the origin and development of spleen and stomach diseases and syndromes in TCM. This has provided reference for related research of spleen and stomach diseases in modern Chinese medicine.

ABSTRACT

OBJECTIVE@#To assess the impact of nonsteroidal anti-inflammatory drugs (NSAIDs) on clinical outcomes of patients receiving anti-PD-1 immunotherapy for hepatocellular carcinoma.@*METHODS@#We conducted a retrospective study among 215 patients with primary liver cancer receiving immunotherapy between June, 2018 and October, 2020. The patients with balanced baseline characteristics were selected based on propensity matching scores, and among them 33 patients who used NSAIDs were matched at the ratio of 1∶3 with 78 patients who did not use NSAIDs. We compared the overall survival (OS), progression-free survival (PFS), and disease control rate (DCR) between the two groups.@*RESULTS@#There was no significant difference in OS between the patients using NSAIDs (29.7%) and those who did not use NSAIDs (70.2%). Univariate and multivariate analyses did not show an a correlation of NSAIDs use with DCR (univariate analysis: OR=0.602, 95% CI: 0.299-1.213, P=0.156; multivariate analysis: OR=0.693, 95% CI: 0.330-1.458, P=0.334), PFS (univariate analysis: HR=1.230, 95% CI: 0.789-1.916, P=0.361; multivariate analysis: HR=1.151, 95% CI: 0.732-1.810, P=9.544), or OS (univariate analysis: HR=0.552, 95% CI: 0.208-1.463, P=0.232; multivariate analysis: HR=1.085, 95% CI: 0.685-1.717, P=0.729).@*CONCLUSION@#Our results show no favorable effect of NSAIDs on the efficacy of immunotherapy in patients with advanced primary liver cancer, but this finding still needs to be verified by future prospective studies of large cohorts.

ABSTRACT

Tetrapyrrole compounds are a class of compounds with important functions. They exist in living organisms and have been widely used in agriculture, food, medicine, and other fields. The cumbersome process and high cost of chemical synthesis, as well as the shortcomings of unstable quality of animal and plant extraction methods, greatly hampered the industrial production and applications of tetrapyrrole compounds. In recent years, the rapid development of synthetic biology has provided new tools for microorganisms to efficiently synthesize tetrapyrrole compounds from renewable biomass resources. This article summarizes various strategies for the biosynthesis of tetrapyrrole compounds, discusses methods to improve its biosynthesis efficiency and future prospects, with the aim to facilitate the research on biosynthesis of tetrapyrrole compounds.

ABSTRACT

OBJECTIVE@#To systematically review the therapeutic effect of acupuncture and moxibustion on postoperative gastrointestinal dysfunction (GID) of gastric cancer with meta-analysis.@*METHODS@#The articles of randomized controlled trials (RCTs) of acupuncture and moxibustion treatment for postoperative GID of gastric cancer were retrieved from the following databases from the time of database establishment to December 31, 2020, including PubMed, EMbase, Cochrane Central Register of Controlled Trials (CENTRAL), China National Knowledge Infrastructure (CNKI), Wanfang database, VIP database and China Biomedical Literature Database (SinoMed). RevMan5.3 software was used for meta-analysis. Using Stata16.0 software, sensitivity analysis and publication bias test were performed.@*RESULTS@#A total of 16 RCTs were included finally, including 1 360 patients, of which, there were 681 cases in the intervention group and 679 cases in the control group. Meta-analysis results showed that acupuncture and moxibustion shortened the time of first flatus (P<0.000 01, MD =-14.52, 95%CI = [-17.31, -11.74]), the time of first bowel sound (P<0.000 01, MD =-10.50, 95%CI =[-13.99, -7.01]) and the time of first defecation (P<0.000 1, MD =-13.79, 95%CI =[-20.09, -7.50]). Meanwhile, acupuncture and moxibustion shortened the time of the first food intake (P<0.000 1, MD =-3.23, 95%CI = [-3.45, -3.00]) and the hospital stay (P<0.000 01, MD =-1.94, 95%CI =[-2.20, -1.69]) after gastric cancer operation, and reduced the incidences of postoperative adverse reactions, i.e. nausea and vomiting (P =0.000 3, RR =0.43, 95%CI =[0.28, 0.68]) and abdominal distention (P =0.000 5, RR =0.41, 95%CI =[0.25, 0.68]).@*CONCLUSION@#Acupuncture and moxibustion can promote the recovery of postoperative gastrointestinal function in the patients with gastric cancer. But, for the comparison among different measures of acupuncture and moxibustion intervention, it needs more high-quality trials for a further verification.

ABSTRACT

Objective To explore the value of DNA repair genes (DRGs) in predicting the effect of immunotherapy on lung adenocarcinoma based on second-generation sequencing technology. Methods The data of lung adenocarcinoma were obtained from the Cancer Genome Atlas, including the testing cohort and the validation cohort. In the testing set, according to the cut-off value of tumor mutational burden (TMB) score 15, the patients with lung adenocarcinoma were divided into two groups: the low TMB score group and the high TMB score group. And we analyzed the relation between TMB and the overall survival of lung adenocarcinoma patients. KRAS and TP53 co-mutation was used as the standard control, the differences in the mutation count and TMB score between only DRGs mutation group and KRAS or TP53 co-mutation groups were analyzed. In the validation cohort, the differences between DRGs and KRAS or TP53 co-mutation groups in TMB, tumor neoantigen burden and PFS were analyzed. Results The patients with TP53/DRGs co-mutation had higher mutation count and TMB score than those patients with only TP53 or DRGs mutation (P < 0.05). The patients with TP53/DRGs co-mutation had higher mutation count and TMB score than those patients with KRAS/TP53 co-mutation (P=0.037, P=0.044). In validation cohort analysis, the TP53/DRGs co-mutation patients also showed higher tumor neoantigens, higher TMB and longer progression-free survival than those patients with only TP53 or DRGs or KRAS/TP53 co-mutation groups. Conclusion TP53/DRGs co-mutation may be served as a pair of potential biomarkers for predicting the efficacy of immunotherapy on lung adenocarcinoma.
