RESUMO

BACKGROUND: Hypoxemia represents the most prevalent adverse event during flexible bronchoscopy procedures aimed at foreign body retrieval in pediatric patients; if not expeditiously managed, it carries the potential for cardiac or respiratory arrest. The specific risk factors contributing to the occurrence of hypoxemia during foreign body FB removal via bronchoscopy have yet to be definitively established. METHODS: This retrospective study included a cohort of 266 pediatric subjects from January 1, 2015, to December 31, 2022, who underwent flexible bronchoscopy for the purpose of FB extraction. In this cohort, the supraglottic airway was used to connect the anesthesia apparatus during the removal procedure. RESULTS: In total, 45 of the pediatric patients (16.9%) experienced episodes of hypoxemia during the FB removal procedure. Multivariate analysis revealed that the following factors were significantly associated with the occurrence of hypoxemia: an operation time exceeding 60 min (odds ratio [OR] 8.55; 95% confidence interval [CI] 3.82-19.13), a maximum diameter exceeding 7 mm (OR 5.03; 95% CI, 2.24-11.29), and the presence of radiological evidence indicating pneumonia (OR 2.69; 95% CI, 1.27-5.69). CONCLUSION: During flexible bronchoscopy procedures aimed at FB removal in pediatric patients, there is an increased susceptibility to hypoxemia. Factors including extended operation duration, larger FB dimensions, and radiographic evidence suggestive of pneumonia significantly contribute to a heightened risk of hypoxemia.

RESUMO

BACKGROUND: The transversus abdominis plane (TAP) block in conjunction with intrathecal morphine has been demonstrated to provide more superior postcesarean analgesia to intrathecal morphine alone. However, the analgesia efficacy of their conjunction has not been demonstrated in patients with severe pre-eclampsia. The study aimed to compare the postcesarean analgesia of TAP block in conjunction with intrathecal morphine versus intrathecal morphine alone in women with severe pre-eclampsia. METHODS: Pregnant women with severe pre-eclampsia undergoing planned cesarean section were randomly allocated into 2 groups to receive TAP block with 20 ml of 0.35% Ropivacaine (TAP group) or with the same volume of 0.9% saline (Sham group) after undergoing elective cesarean section under spinal anaesthesia with 15 mg of 0.5% Ropivacaine plus 0.1 mg of morphine. The outcomes for this analysis include the visual analog scale (VAS) pain score at rest and with movement at 4,8,12,24 h after TAP block was performed, times of use of intravenous patient-controlled analgesia (PCA) within 12 h after anesthesia, the occurrence of maternal side effects, maternal satisfaction, and Apgar score at 1 and 5 min of newborns. RESULTS: 119 subjects receive TAP block with 0.35% Ropivacaine (n = 59)or 0.9% saline (n = 60). At 4,8, 12 h after TAP block, the TAP group reported lower VAS score at rest [at 4 h: 1(0,1) vs. 1(1,2), P < 0.001; at 8 h:1(1,1) vs. 1(1.5,2),P < 0.001; at 12 h:1(1,2) vs. 2(1,2),P = 0.001] and higher satisfaction [53(89.9%) vs.45(75.0%), P < 0.05]. There were no differences between groups in VAS score at 24 h at rest and at all time points above with movement, times of use of PCA within 12 h after anesthesia, maternal side-effect, and Apgar score at 1 and 5 min of newborns. CONCLUSIONS: In conclusion, The TAP block performed in conjunction with intrathecal morphine may not reduce opioid consumption, but it could reduce VAS scores at rest in the first 12 h after cesarean section in women with severe pre-eclampsia, and improve maternal satisfaction, which is worthy of clinical promotion.

RESUMO

BACKGROUND: Reintubation is a severe complication during foreign body (FB) removal that uses flexible bronchoscopy. OBJECTIVE: To investigate the incidence and risk factors for reintubations in children undergoing FB extraction by flexible bronchoscopy in a single center. DESIGN: A retrospective cross-sectional study. SETTING: All children with foreign body aspiration at Fujian Maternity and Child Health Hospital, Affiliated Hospital of Fujian Medical University from January 2015 to December 2020. PATIENTS: Children with FB removal using a flexible bronchoscopy were enrolled in the trial according to the inclusion criteria. MEASUREMENTS: Both multivariable and logistic regression analyses were used to analyze the association between characteristic data and reintubations. The results were presented as odds ratios (ORs) with 95% confidence intervals (CIs). RESULTS: In total, 244 patients met with the inclusion criteria and were included in the analysis. Among those participants, 28 children (11.5%) underwent reintubations after FB removal by flexible bronchoscopy. Independent factors associated with reintubations were identified as operative time ≥ 60 min [OR: 3.68, 95% CI (1.64-8.82)] and ASA ≥ III [OR: 5.7, 95% CI (1.23-26.4)]. CONCLUSIONS: Children undergoing FB removal by a flexible bronchoscopy may encounter with a high incidence of postoperative reintubations. Both long operative duration and a severe physical status cause a growing risk of reintubations.

RESUMO

OBJECTIVES: Our study aimed to investigate the clinical efficacy of argon-helium cryoablation and its effects on the immune function of patients with neck malignant tumours. DESIGN: Retrospective study. SETTING: Single-institution academic tertiary care centre. METHODS: Totally, 180 patients harbouring head and neck malignant tumours were divided into the argon-helium cryoablation group (n = 150) and the radiotherapy group (n = 50). The efficacy of the two groups was compared, and the immune function was observed. RESULTS: The short-term clinical effect of the argon-helium cryoablation group was significantly higher than that of the radiotherapy group (P < .05). After treatment, the CD3+, CD4+, CD8+ and CD4+/CD8+ of the argon-helium cryoablation group were significantly better than those of the radiotherapy group (P < .001). The results of TNF-α, IL-1 ß and CRP in the argon-helium cryoablation group were significantly better than that in the radiotherapy group (P < .001). CONCLUSION: Argon-helium cryoablation could effectively improve the immune function, 5-year survival rate and local remission rate.

RESUMO

The aim of this study was to determine the radio sensitization of docetaxel in human esophageal squamous carcinoma ECA109 cell line by observing the effects of docetaxel in ECA109 cell proliferation, cell cycle distribution, apoptosis rate and related protein expression. Docetaxel inhibits the proliferation in ECA109 cell line in a dose-dependent and time-dependent manner, and 1nM was chosen for radio sensitization according to the inhibition curves. The D0 and SF2 values of ECA109 cells were 3.00Gy and 0.95, respectively, and of docetaxel (1nM) with irradiation group were 2.54Gy and 0.88. G0/G1 decreased (P<0.05), G2/M phase saw a spike (P<0.05) in the docetaxel with radiation group at 12h, 24h and 48h, while the apoptotic index witnessed a surge at 24h and 48h (P<0.05). The docetaxel with radiation group obtained a higher expression of p21 and bax protein than the docetaxel group and the radiation group (P<0.05), and a higher ratio of bcl-2/bax than the others (P<0.05). Docetaxel could inhibit the proliferation in ECA109 cell line. p21, bax, bcl-2 and other related proteins can regulate cell cycle phase distribution and induce cell apoptosis, thereby increasing the radiosensitivity effect of docetaxel in ECA109 cell line.

RESUMO

BACKGROUND: Intravenous remifentanil patient-controlled analgesia (RPCA) is an alternative for epidural analgesia (EA) in labor pain relief. However, it remains unknown whether RPCA is superior to EA in decreasing the risk of intrapartum maternal fever during labor. METHODS: According to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a systematic review and meta-analysis was performed by searching PubMed, EMBASE and the Cochrane Central Register of Controlled Trials from inception to April 2019. All randomized controlled trials (RCTs) investigating the risk of intrapartum maternal fever with RPCA compared with EA alone or EA in combination with spinal analgesia during labor were included. RESULTS: A total of 825 studies were screened, and 6 RCTs including 3341 patients were identified. Compared with EA, RPCA was associated with a significantly lower incidence of intrapartum maternal fever (risk ratio [RR] 0.48, P = 0.02, I2 = 49%) during labor analgesia. After excluding 2 trials via the heterogeneity analysis, there was no difference in the incidence of intrapartum fever between patients receiving RPCA and those receiving EA. Satisfaction with pain relief during labor was lower in the RPCA group than that in the EA group (- 10.6 [13.87, - 7.44], P < 0.00001, I2 = 0%). The incidence of respiratory depression was significantly greater in the RPCA group than that in the EA group (risk ratio 2.86 [1.65, 4.96], P = 0.0002, I2 = 58%). The incidence of Apgar scores < 7 at 5 min in the RPCA group was equivalent to that in the EA group. CONCLUSION: There is no solid evidence to illustrate that the incidence of intrapartum maternal fever is lower in patients receiving intravenous RPCA than in patients receiving EA.

RESUMO

Aberrant expression of long non-coding RNAs (lncRNAs) has been observed in hepatocellular carcinoma (HCC) and confirmed to participate in the initiation and progression of HCC. In the present study, we identified a novel functional lncRNA, hedgehog-interacting protein antisense RNA 1 (HHIP-AS1). The expression levels of HHIP-AS1 were significantly decreased in HCC tissues. Downregulation of HHIP-AS1 expression correlated with larger tumor size, metastasis, and advanced TNM stage, and also predicted worse overall survival rate of HCC patients. Through performing overexpression and knockdown experiments, the biological function of HHIP-AS1 was identified to suppress HCC cell proliferation, migration and invasion, while promote apoptosis. Further investigation showed that HHIP-AS1 interacted with and positively regulated the stability of HHIP mRNA in a HuR-dependent manner. HHIP-AS1 exerted its suppressive effects through HHIP. Taken together, our findings demonstrate that HHIP-AS1 represses HCC progression by promoting HHIP expression, and indicate that the use of HHIP-AS1 may offer a promising treatment for HCC patients.

RESUMO

Aluminum phosphide (AlP) is an effective and cheap pesticide that is commonly used worldwide, but it is also a common cause of human poisoning and carries a high mortality rate. AlP reacts with moisture in air, water, and hydrochloric acid in the stomach to produce phosphine (PH3) gas. Two routes of exposure are ingestion of AlP and inhalation of phosphine generated by the action of moisture on AlP. Absorbed phosphine is rapidly metabolized into phosphite and hypophosphite. A method is described for the analysis of the phosphine metabolites in various biological matrices. The method involves reacting the sample with zinc and aqueous H2SO4 in a volatile organic analysis vial. The metabolites were transformed into phosphine gas and then analyzed by headspace gas chromatography coupled with mass spectrometry (HS-GC-MS). This method is capable of detecting quantities of PH3 as low as 0.2 µg/mL in a sample. After validation, the method was applied to animal experiments and a real case of human AlP intoxication. This approach has the advantage of detecting metabolites of PH3, in case the PH3 was converted, and can be considered a useful additional tool for the diagnosis of AlP poisoning in forensic science.

RESUMO

In order to guarantee the safety and accuracy of the whole treating process as well as better link up of each section during the treatment, we did research in order to establish a project concerning the process quality control (PQC) of treating liver cancer with CyberKnife. From the safety and accuracy point of view, we divided the whole process of treating liver cancer with CyberKnife into ten links, i.e. the registration of patients' information, the im plantation of fiducial markers, fixation of body posture, CT localization, target delineation, design of the treatment plan, quality assurance in physics, implementation of the treatment plan, inspection on the correctness and data archiving. We analyzed the possible mistakes in each link and the consequences brought by them. To smoothly connect all the links, a special part "Attention" was added between every two links. Various wrong operations which may influence the safety and accuracy of treatment were illustrated, and the consequences brought by them were also ex plained. The "Attention" part among links offers important information for the next step, and gives us reminding and warnings. The project of quality control covers all the important links when treating liver cancer with Cy berKnife. It offers regulations, reminding and warning for us so that the safety and accuracy of treatment can be guaranteed, and the work of all staff could be closely connected.

RESUMO

Labor epidural analgesia (LEA) is associated with increased maternal body temperature; however, the responsible mechanism is unknown. Recent studies suggest that changes in EA affect the incidence of fever and that epidural sufentanil supplementation enhances analgesia and reduces the amount of local anesthetic. The aim of this study was to evaluate the effect of different concentrations of sufentanil combined with ropivacaine on intrapartum fever during delivery. We performed a retrospective study comparing maternal fever rates in patients receiving labor analgesia between December 2018 and January 2019. Each patient receiving different concentrations of sufentanil in their EA received either proposal H (0.08% ropivacaine + 0.4 µg/mL sufentanil) or proposal L (0.08% ropivacaine + 0.2 µg/mL sufentanil), with the same nulliparous status. The primary outcome of this study was the incidence of intrapartum maternal fever, which was defined as any temperature ≥ 38°C during labor using Fisher exact test. Secondary outcome measures included visual analog scale (VAS) pain scores, birth events, and neonatal outcomes. We observed a perinatal fever incidence rate of 11.7% in the group receiving proposal L, while the incidence rate was 19.8% in the group receiving proposal H (P = .001). Five hours after administration, the average body temperature of the puerpera decreased significantly in the proposal L group compared with proposal H group. In addition, treatment with 0.2 µg/mL sufentanil provided satisfactory pain relief during labor, shortened the first stage of labor and total labor time, reduced oxytocin use, and had no significant adverse effects on neonatal outcomes. EA may increase the risk of intrapartum epidural-associated fever. Compared with the 0.4 µg/mL sufentanil group, the 0.2 µg/mL sufentanil group can provide better analgesia and improve maternal fever. These retrospective results highlighted the importance of prospective and mechanistic studies of maternal fever associated with intraspinal analgesia.

RESUMO

Postoperative acute kidney injury (AKI) is a common complication that is associated with chronic kidney disease, early postsurgical mortality, and prolonged hospital stays. Preterm neonates who undergo surgery are at risk factors for AKI due to underdeveloped kidneys. To date, little is known about the incidence and perioperative risk factors for AKI in preterm neonates undergoing noncardiac surgery. Preterm neonates who underwent noncardiac surgery between January May 1, 2020, and February 28, 2023, were enrolled in the trial according to the inclusion criteria. Both multivariable and logistic regression analyses were used to analyze the associations between characteristic data and AKI. In total, 106 preterm neonates met the inclusion criteria, and 25 preterm neonates (23.6%) developed postoperative AKI. Multivariate analysis revealed that the factors associated with AKI were gestational age < 32 weeks [OR: 4.88; 95% CI (1.23-19.42)], preoperative sepsis [OR: 3.98; 95% CI (1.29-12.28)], and intraoperative hypotension [OR: 3.75; 95% CI (1.26-11.15)]. Preterm neonates who developed AKI were more likely to have longer hospital length of stays (38 [18,69] days vs. 21[12,46]) and higher medical costs (93,181.6 [620450.0,173,219.0] ï¿¥ vs. 58,134.6 [31015.1,97,224,1) ï¿¥ than neonates who did not develop AKI. Preterm neonates who underwent noncardiac surgery had a high incidence of AKI. Independent risk factors for AKI in preterm neonates who underwent noncardiac surgery were low gestational age, preoperative sepsis, and intraoperative hypotension. Preterm neonates who developed AKI were more likely to have longer hospital stays and higher medical costs.

RESUMO

To develop a simple, validated method for identifying and quantifying 1,3-butadiene (BD) in human blood by gas chromatography-mass spectrometry (GC-MS) and head-space gas chromatography (HS-GC). BD was identified by GC-MS and HS-GC, and quantified by HS-GC. The method showed that BD had a good linearity from 50 to 500 microg/mL (r > 0.99). The limits of detection and quantification were 10 microg/mL and 50 microg/mL, respectively. Both the intra-day precision and inter-day precision were < 6.08%, and the accuracy was 96.98%-103.81%. The method was applied to an actual case, and the concentration of BD in the case was 242 microg/mL in human blood. This simple method is found to be useful for the routine forensic analysis of acute exposure to BD.

RESUMO

OBJECTIVE: To establish the electricity plate digestion and inductively coupled plasma-mass spectrometry (ICP-MS) method for determination of 33 inorganic elements in human hair. METHODS: Lithium (6Li), Germanium (72Ge), Yttrium (89Y), Indium (115In), and Terbium (159Tb) were used as internal standards. The electric heating board digestion in a mixture of nitric acid and hydrogen peroxide was used as the pre-treatment of the hair. Thirty-three inorganic elements in human hair were analyzed by ICP-MS method. RESULTS: The detection limit of ICP-MS was 0.0001 microg/g(Th)-10.9 microg/g (Ca) and the limit of quantitation was 0.0005 microg/g (Th)-25 microg/g (Ca). The recovery rate of this method was 86%-113%. The RSD for the intra-day and inter-day were less than 9.2%. The method was not statistically different from microwave digestion method. CONCLUSION: This method is highly efficient and accurate. It can be used for analysis of 33 inorganic elements in human hair.

RESUMO

This research aims to combine the pursuit of literacy cultivation with a focused investigation into the evidence of game-based teaching (GBT). To achieve this, the study employs a mixed-methods approach including the interview method, Delphi method, and network hierarchical analysis (ANP) to analysis Expert opinions and construct a comprehensive GBT evaluation index system. The results indicated that a comprehensive GBT evaluation index system is comprised of five primary indicators: teaching objectives, game-based teaching methods, teaching content, game-based teaching processes, and game-based teaching characteristics. Additionally, there are 19 secondary indicators, such as objective content, game presentation, context construction, and flow experience. This study expects to effectively capture the unique attributes of game-based classes and to assist teachers in improving the design of GBT activities in practical applications.

RESUMO

Colchicine has been widely used in the treatment of acute gout over the years, but it has a narrow therapeutic index, and overdose can be life threatening. A method using ultra-high-performance liquid chromatography-tandem mass spectrometry system was applied in two fatal cases of colchicine poisoning in this study to the determination of colchicine in blood. In case 1, a 19-year-old man suffered from depression and ingested 160 colchicine tablets (each 0.5 mg). The concentration of colchicine in his blood samples showed a fluctuating trend and kept above the therapeutic steady-state concentration for 5 days. In case 2, a 70-year-old female patient with a history of gout and chronic colchicine intake ingested five times the usual dose of colchicine (5 mg) and died after 12 days of medical care, with 5 ng/mL of colchicine in her blood sample. Our findings suggest that the delayed elimination and accumulation in humans after colchicine overdose could keep the concentration of colchicine maintaining above the therapeutic steady-state concentration for many days before dying, probably along with a fluctuating trend.

RESUMO

PURPOSE: Knowing and analyzing the characteristics and trends of forensic toxicology cases in a certain area is particularly important for a local government to establish an effective prevention and control system. The purpose of this work was to summarize data from forensic toxicology cases received by the Academy of Forensic Sciences (AFS) in 2021. METHODS: As requested by the police or according to the details of cases, samples were systematically screened or analyzed by various methods. Liquid chromatography-tandem mass spectrometry and gas chromatography-mass spectrometry were used to identify medicinal drugs, drugs of abuse, pesticides, poison gases, etc. RESULTS: AFS received a total of 17,758 cases in 2021, of which 314 cases underwent autopsy. The main cause of death was sudden death, and the manner of death was mainly accident. Among 13,744 drug abuse cases, the number of positive cases was 1721, with a positive rate of 12.5%, and synthetic cannabinoids were the most frequently detected substances. In 3640 traffic cases, 85.3% of drivers were suspected of drunk driving. In 103 poisoning cases, hydrogen sulfide poisoning and pesticide suicide account for a large proportion. In drug-facilitated crimes, zolpidem was the most frequently tested component. In 55 case of dog poisonings, the main poisons were cyanides and succinylcholine, and the main poisoning tools were poisonous baits and poisonous syringe darts. CONCLUSIONS: This study profiles the toxicological characteristics of forensic toxicological cases conducted at the AFS in 2021 and provides a scientific basis for poisoning cases and drug abuse prevention.

RESUMO

Inductively coupled plasma-mass spectrometry (ICP-MS) is the most common technique for elements analysis at present. ICP-MS with high sensitivity and wide linear range can be applied to multi-elements analysis in blood and urine. This paper reviews the common means of sample pretreatment (direct dilution method and wet digestion method), the method for correction of mass spectral interference and non-interference, the main influence factors of analysis results, and provides an outlook of the application of ICP-MS in forensic toxicological analysis.

RESUMO

Background: Gastric signet ring cell carcinoma (SRCC) has shown a growth growing trend worldwide, but its clinicopathological features and prognostic-related risk factors have not been systematically studied. This systematic review was devoted to this. Method: PubMed, Embase, Cochrane Library, and Web of Science databases were retrieved, and retrospective cohort studies comparing clinicopathological features and related risk factors in SRCC patients were included. Results: In SRCC patient population, males were more than females (male, OR = 1.38, 95% CI: 1.20-1.60); N3 patients were more than N0-2 patients (N0-2, OR = 3.19, 95% CI: 1.98-5.15); M1 patients were more than M0 patients (M0, OR = 3.30, 95% CI: 1.88-5.80); patients with tumor > 5 cm were more than those with tumor (≤5 cm, OR = 7.36, 95% CI: 1.33-40.60). Patients with age < 60 years (age ≥ 60 years, OR = 1.03, 95% CI: 1.01-1.05), lymphatic vessel invasion (no, OR = 1.74, 95% CI: 1.03-2.45), T2 (T1, OR = 1.17, 95% CI: 1.07-1.28) and T4 (T1, OR = 2.55, 95% CI: 2.30-2.81) stages, and N1 (N0, OR = 1.73, 95% CI: 1.08-2.38), N2 (N0, OR = 2.24, 95% CI: 1.12-3.36), and N3 (N0, OR = 3.45, 95% CI: 1.58-5.32) stages had higher hazard ratio (HR). Conclusion: SRCC may occur frequently in male. Age, lymphatic vessel invasion, TN, and M stage may be risk factors for poor prognoses of SRCC patients.
