OBJECTIVE: We aimed to investigate the patterns of fasting blood glucose (FBG) trajectories and analyze the relationship between various occupational hazard factors and FBG trajectories in male steelworkers. METHODS: The study cohort included 3,728 workers who met the selection criteria for the Tanggang Occupational Cohort (TGOC) between 2017 and 2022. A group-based trajectory model was used to identify the FBG trajectories. Environmental risk scores (ERS) were constructed using regression coefficients from the occupational hazard model as weights. Univariate and multivariate logistic regression analyses were performed to explore the effects of occupational hazard factors using the ERS on FBG trajectories. RESULTS: FBG trajectories were categorized into three groups. An association was observed between high temperature, noise exposure, and FBG trajectory ( P < 0.05). Using the first quartile group of ERS1 as a reference, the fourth quartile group of ERS1 had an increased risk of medium and high FBG by 1.90 and 2.21 times, respectively (odds ratio [ OR] = 1.90, 95% confidence interval [ CI]: 1.17-3.10; OR = 2.21, 95% CI: 1.09-4.45). CONCLUSION An association was observed between occupational hazards based on ERS and FBG trajectories. The risk of FBG trajectory levels increase with an increase in ERS.

Objective To compare the clinical safety and efficacy of CT-guided hook-wire localization of≤10mm pulmonary ground-glass nodule(GGN)via different path ways before video-assisted thoracoscopic surgery(VATS).Methods The clinical data of a total of 128 patients with 10 mm pulmonary GGN,who received CT-guided hook wire localization before VATS at The Third Hospital of Mianyang of China between July 2018 and March 2023,were retrospectively analyzed.According to the puncturing localization path way mode,the patients were divided into vertical puncturing group(n=88)and non-vertical puncturing group(n=40).The number of puncturing times,the time spent for puncturing localization,the success rate of puncture,the operation time of VATS,and puncture-related complications of the two groups were recorded.Results No statistically significant differences in the gender,age,smoking history,GGN location,puncture position,nodule size,density characteristics of GGN,emphysema,and nodules-pleura distance existed between the two groups(all P＞0.05).Compared with non-vertical puncturing group,in vertical puncturing group the number of puncturing times was smaller,the time spent for localization was shorter,the incidence of pneumothorax was lower,and the operation time of VATS was shorter,the differences in all the above indexes between the two groups were statistically significant(all P＜0.05);and the subgroup analysis of patients whose GGN was overlapped with rib shadow obtained the same results.Binary logistic regression analysis revealed that non-vertical puncturing and the number of puncturing times were the independent risk factors for the occurrence of pneumothorax.Conclusion CT-guided hook-wire localization of≤10mm pulmonary GGN before VATS is clinically safe and effective.Under the condition when the lesion can be localized within the range of 2.0cm and the shadow overlapping of GGN with the rib and blood vessel can be effectively avoided,vertical puncturing path way mode should be preferred,which can effectively reduce the incidence of pneumothorax and shorten the operation time of VATS.

Objective:This study aims to evaluate the incidence of postoperative malnutrition in colorectal cancer patients who underwent curative colorectal cancer surgery using the Golbal Leadership Initiative on Malnutrition(GLIM)criteria,and to explore the impact of malnutrition defined by the GLIM criteria on short-term clinical outcomes in patients with colorectal cancer.Method:We included a prospective cohort of 171 patients who underwent curative colorectal cancer surgery in Chongqing JiuLongpo People's Hospital from September 2022 to May 2023.Nutritional Risk Screening 2002(NRS 2002)was used for nutritional risk screening and GLIM criteria was used for the diagnosis of malnutrition.To compare the short-term postoperative clinical outcomes between the well-nourished group and the malnourished group under the GLIM criteria.Logistic regression analysis was conducted to analyze the risk factors of postoperative complications.Result:Among the included cases,nutritional screening data showed that 74(43.27％)patients were considered to be at risk of malnutrition(NRS 2002≥3),while based on GLIM criteria,63 patients(36.84％)were diagnosed as malnutrition.Univariate logistic regression analysis showed that GLIM-defined malnutrition was associated with total postoperative complications[odds ratio:2.075(95％CI:1.292～3.333),P=0.002].Multivariat analysis showed that women,BMI＜18.5kg/m2,smoking history,low differentiation of tumor,sarcopenia,laparotomy,low prealbumin,were independent risk factors for total postoperative complications.Conclusions:The nutritional diagnosis based on the GLIM criteria can effectively reflect the preoperative nutritional status of patients with colorectal cancer.GLIM-defined preoperative malnutrition can predict the risk of short-term complications in colorectal cancer patients who underwent curative colorectal cancersurgery.

Single-arm trial refers to a clinical trial design that does not set up parallel control group, adopts open design, and does not involve randomization and blind method. These features, on the one hand, speed up the process of clinical trials, significantly shorten the time to market and meet the needs of patients with advanced malignancies, but also lead to the uncertainty of single-arm clinical trials themselves. Recently, the US Food and Drug Administration held a meeting of the oncologic drug advisory committee to discuss six tumor indications that have been accelerated approved, which once again triggered the discussion of single-arm trials. The basis of accelerated approval by single-arm trial is actually a compromise on the level of evidence-based medical evidence requirements after assessing the benefit risk. Therefore, the sponsor should strictly grasp the applicable conditions of single-arm trial in anti-tumor drugs and conduct single-arm trial scientifically. Post-marketing clinical trial should be implement as early as possible to ensure the benefit of patients. Based on the characteristics of single-arm trial, combined with two guidance relevant to single-arm trial issued by National Medical Products Administration recently, this article is supposed to propose and summarize the strategy of single-arm trial supporting the marketing of anti-tumor drugs.

Aim To develop an LC-MS/MS method for the determination of prucalopride(PCP)in human plasma.Methods Prucalopride -13CD3(dPCP)was used as the internal standard.The analytes were extracted from human plasma through liquid-liquid extraction method using ethyl acetate, followed by being dried, and then the reconstitution was injected into LC-MS/MS systems.Agilent ZORBAX SB C18(3.0×100 mm, 3.5 μm)column and isocratic elution system composing of methanol and 1 mmol·L-1 ammonium acetate(80:20, V/V)provided chromatographic separation of PCP and dPCP.AB Sciex API4000 mass spectrometer equipped with an electrospray ionization source in positive ion mode was employed for mass detection, and data acquisition was carried out in multiple reaction monitoring(MRM)mode.The mass transition ion-pair was followed as m/z 368.4/196.0 for PCP and m/z 374.4/198.0 for dPCP.Results PCP and dPCP were eluted at 3.6 min, with no interference in human blank plasma.PCP in human plasma showed good linearity over the concentration range of 0.058 96-7.547 μg·L-1 with the correlation coefficient of 0.996 3-0.999 6.The lower limit of quantitation of this method was 0.058 96 μg·L-1.The intra-batch and inter-batch accuracy ranged from 98.29% to 108.2%, with good precision(CV<5.2%).The average matrix factors of normal, haemolysed and lipaemic matrix human samples all ranged from 96.48% to 106.3% with CV less than 8.39%.The average extraction recoveries of PCP at low, medium and high concentrations were 89.88%, 95.27% and 94.52% respectively, with CV less than 7.21%.PCP was stable in human samples after 6 h at room temperature, 60 h at -20 ℃, 56 days or three freeze-thaw cycles at -80 ℃; meanwhile, the processed plasma samples remained stable after being stored for 24 hours in autosampler at 8 ℃.Furthermore, PCP in human blood samples was proved to be stable after 4 h at room temperature.Conclusions The present LC-MS/MS method for the determination of PCP in human plasma was convenient, accurate, sensitive, stable, specific and reproducible and was proved to be suitable for the clinical pharmacokinetics and bioequivalence studies of PCP preparations.

Objective:To analyze the risk factors of fatal outcome in patients with severe COVID-19.Methods:The clinical characteristics of 107 patients with severe COVID-19 admitted in Renmin Hospital of Wuhan University from February 12 to March 12, 2020 were retrospectively analyzed. During the hospitalization 49 patients died (fatal group) and 58 patients survived (survival group). The clinical characteristics, baseline laboratory findings were analyzed using R and Python statistical software. The risk factors of fatal outcome in patients with severe COVID-19 were analyzed with multivariate logistic regression.Results:Univariate analysis showed that the two groups had statistically significant differences in age, clinical classification, dry cough, dyspnea and laboratory test indicators ( P<0.05 or <0.01). The random forest model was used to rank the significance of the statistically significant variables in the univariate analysis, and the selected variables were included in the binary logistic regression model. After stepwise regression analysis, the patient’s clinical type, age, neutrophil count, and the proportion of CD3 cells are independent risk factors for death in severe COVID-19 patients. Dry cough is an independent protective factor for the death of severe COVID-19 patients. Conclusion:COVID-19 patients with fatal outcome are more likely to have suppressed immune function, secondary infection and inflammatory factor storm. These factors may work together in severe patients, leading to intractable hypoxemia and multiple organ dysfunction and resulting in fatal outcome of patients. The study indicates that timely intervention and treatment measures against above factors may be effective to save the lives of patients with severe COVID-19.

OBJECTIVE: To evaluate the effects of a 48-week course of adefovir dipivoxil (ADV) plus Chinese medicine (CM) therapy, namely Tiaogan Jianpi Hexue () and Tiaogan Jiedu Huashi () fomulae, in hepatitis B e antigen (HBeAg)-positive Chinese patients. METHODS: A total of 605 HBeAg-positive Chinese CHB patients were screened and 590 eligible participants were randomly assigned to 2 groups in 1:1 ratio including experimental group (EG, received ADV plus CM) and control group (CG, received ADV plus CM-placebo) for 48 weeks. The major study outcomes were the rates of HBeAg and HBV-DNA loss on week 12, 24, 36, 48, respectively. Secondary endpoints including liver functions (enzymes and bilirubin readings) were evaluated every 4 weeks at the beginning of week 24, 36, and 48. Routine blood, urine, and stool analyses in addition to electrocardiogram and abdominal B scan were monitored as safety evaluations. Adverse events (AEs) were documented. RESULTS: The combination therapy demonstrated superior HBeAg loss at 48 weeks, without additional AEs. The full analysis population was 560 and 280 in each group. In the EG, population achieved HBeAg loss on week 12, 24, 36, and 48 were 25 (8.90%), 34 (12.14%), 52 (18.57%), and 83 (29.64%), respectively; the equivalent numbers in the CG were 20 (7.14%), 41 (14.64%), 54 (19.29%), and 50 (17.86%), respectively. There was a statistically significant difference between these group values on week 48 (P<0.01). No additional AEs were found in EG. Subgroup analysis suggested different outcomes among treatment patterns. CONCLUSION Combination of CM and ADV therapy demonstrated superior HBeAg clearance compared with ADV monotherapy. The finding indicates that this combination therapy may provide an improved therapeutic effect and safety profile (ChiCTR-TRC-11001263).
