ABSTRACT

Objective:To investigate the safety and efficacy of FOLFOX (5-fluorouracil + calcium folinate + oxaliplatin) hepatic arterial infusion chemotherapy (FOLFOX-HAIC) combined with immune and targeted therapy as triple combination therapy for patients with single China Liver Cancer Staging (CNLC) Ⅰb hepatocellular carcinoma.Methods:A total of 20 patients with single CNLC Ⅰb hepatocellular carcinoma who received FOLFOX-HAIC combined with immune and targeted therapy as triple combination therapy in the First Affiliated Hospital of Guangxi Medical University from October 2021 to August 2022 were included. The clinical data of all patients was retrospectively analyzed. There were 18 males and 2 females, with the age of (55.1±9.9) years. Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 and Modified Response Evaluation Criteria in Solid Tumors (mRECIST) were used to evaluate the efficacy of FOLFOX-HAIC combined with immune and targeted therapy, and the clinical safety of triple combination therapy was evaluated by common terminology criteria for adverse events 4.0.Results:According to RECIST 1.1, objective response rate of 20 patients was 70.0% (14/20) and disease control rate was 100.0% (20/20) after 2 cycles of treatment (one cycle of FOLFOX-HAIC plus programmed death-1 antibody). According to mRECIST, objective response rate was 90.0% (18/20) and the disease control rate was 100.0% (20/20) after 2 cycles of treatment. Following the treatment, 12 patients (60.0%) received liver tumor resection, and all of them achieved R 0 resection, 2 patients (10.0%) received radiotherapy, 3 patients (15.0%) stopped drug treatment for surgery, 2 patients (10.0%) refused surgery, and 1 patient (5.0%) died of multiple organ failure caused by immune hepatitis. According to pathological results, 3 patients (25.0%, 3/12) achieved pathological complete response, and 4 patients (33.3%, 4/12) achieved major pathological response. In the safety evaluation, the overall incidence of adverse events was 100.0% (20/20). Seven patients (35.0%) had grade 3 adverse events and 1 patient (5.0%) died of multiple organ failure due to immune hepatitis (grade 5). Grade 1-3 adverse events could be relieved after symptomatic treatment. Conclusion:The triple combination therapy of FOLFOX-HAIC combined with immune and targeted therapy is safe and has high objective response rate and disease control rate, which could be a new strategy for the neoadjuvant treatment of hepatocellular carcinoma.

ABSTRACT

Leiomyosarcoma of urinary bladder (LMS-UB) is a highly malignant mesenchymal tumor, accounting for less than 0.5% of all bladder malignancies, with a predominant clinical presentation of hematuria. Here we report a case of low-grade LMS-UB. A 44-year-old male patient was admitted to the hospital with urodynia for 2 weeks. The patient's pelvis CT showed a mass on the right part of the bladder. For this reason, he was initially diagnosed with bladder cancer. We performed a robot-assisted laparoscopic enucleation of the bladder tumor and low-grade LMS-UB was diagnosed with the histopathological examination. He underwent 5 cycles of adjuvant chemotherapy after surgery. At 19months postoperative follow-up, the patient had no symptoms, recurrence, or distant metastasis. There is no report on the treatment of LMS-UB with minimally invasive enucleation worldwide. This case provides a new comprehensive treatment method of enucleation combined with adjuvant chemotherapy for early low-grade LMS-UB to reduce complications and improve patients' quality of life after surgery.

ABSTRACT

Abstract Introduction: The objective of this study is to evaluate the efficacy and midterm prognosis of transcatheter device closure of atrial septal defects (ASDs) in sexagenary patients in China. Methods: Forty-six sexagenary patients who underwent transcatheter device closure of ASDs in our hospital were included in this study. The patients' preoperative and postoperative clinical symptoms, echocardiographic results, and quality of life were investigated and analyzed. Results: Of the 46 sexagenary patients who participated in the study, 40 completed the study. After ASD closure, the clinical symptoms of the patients significantly improved, and the number of patients with dyspnea and palpitations significantly decreased after the operation. According to the echocardiographic results, few patients had a tiny residual shunt after closure, but the shunt disappeared completely at the three-month follow-up. The size of the right ventricular cavity was significantly smaller postoperatively compared with preoperatively. Regarding the patients' quality of life, their feedback in all dimensions of the 36-Item Short-Form Health Survey (or SF-36) was significantly improved at the three-month follow-up, and it remained improved at the one-year follow-up. Conclusion: The clinical outcomes and subjective quality of life of sexagenary patients with ASDs improved significantly after transcatheter device closure of ASDs. Therefore, we believe that for sexagenary patients with ASDs, transcatheter device closure is a favorable treatment.

ABSTRACT

Objective: To explore the relationship between obesity status and death stratified by different multi-morbidity status in older adults in China. Methods: Data for older Chinese adults aged ≥65 years were from Chinese Longitudinal Healthy Longevity Survey (CLHLS). Multi-morbidity patterns based on 13 chronic conditions were explored using exploratory factor analysis. Cox models were used to examine relationships between obesity status and death stratified by disease count and multi-morbidity patterns at baseline, respectively. Besides, obesity status was defined by baseline body mass index and waist circumference. Results: A total of 6 272 participants were included in the analyses. Multi-morbidity including cardio-metabolic, sensory perception and other patterns were identified. For those without any chronic condition, compared with those without central obesity, central obesity was associated with a higher risk for death (HR=1.66, 95%CI:1.04-2.66). For those only with one chronic condition, compared with normal weight, underweight was associated with a higher risk for death (HR=1.41, 95%CI: 1.10-1.80). For those with multi-morbidity, compared with normal weight, underweight increased the risk for death (HR=1.19, 95%CI:1.05-1.34). Compared with those without central obesity, central obesity decreased the risk for death (HR=0.88, 95%CI:0.78-0.99). Conclusions: Relationships between obesity status and death varied by multi-morbidity status in older adults in China. Underweight and non-central obesity were associated with increased risks for death in older adults with only one chronic disease or multi-morbidity. Therefore, it is necessary to pay attention to multi-morbidity status in the management of obesity in older adults and provide effective targeted body weight management plan.

ABSTRACT

【Objective】 To provide reference for formulating relatively unified quality control strategies and meeting the requirements of homogenization construction of blood banks across Chongqing area by retrospectively analyzing sampling results of different blood components during the past two years in all levels of blood banks in Chongqing area. 【Methods】 The key quality data of blood components prepared by 6 blood banks in Chongqing were analyzed retrospectively. According to the issuing units to the clinical during the past two years, the research objects were selected as leukocyte-depleted suspended RBCs, cryoprecipitate, pathogen inactivated fresh frozen plasma(FFP) and apheresis platelets. The quality data of the above-mentioned blood components from January 2019 to June 2021 were collected and analyzed. 【Results】 For leukocyte-depleted suspended RBCs(1U)prepared by 5 blood banks, statistically significant differences in Hb, residual white blood cells and hemolysis rate at the end of storage, except for Hct, were noticed(P<0.05). For cryoprecipitate, the content of blood coagulation factor Ⅷ and fibrinogen were statistically different among 3 blood banks in 1U specification(P<0.05) and among 5 blood banks in 2U specification(P<0.05). For pathogen inactivated FFP, the content of blood coagulation factor Ⅷ, plasma proteins, and residual methylene blue were statistically different among 3 blood banks(P<0.05). For apheresis platelets, Plt, white/red blood cells contamination and pH at the end of storage were statistically different among 3 blood banks(P<0.05). 【Conclusion】 The quality data of blood components, prepared by different blood banks, meet the requirements of national standard, however, certain differences are existing among blood banks.Key points during the process of collection, preparation, storage and transportation need to be cleared and unified, so as to reduce the differences between each other, and determine the direction and basis for homogeneity construction in the next step.

ABSTRACT

BACKGROUND@#Since 2019, a novel coronavirus named 2019 novel coronavirus (2019-nCoV) has emerged worldwide. Apart from fever and respiratory complications, acute kidney injury has been observed in a few patients with coronavirus disease 2019. Furthermore, according to recent findings, the virus has been detected in urine. Angiotensin-converting enzyme II (ACE2) has been proposed to serve as the receptor for the entry of 2019-nCoV, which is the same as that for the severe acute respiratory syndrome. This study aimed to investigate the possible cause of kidney damage and the potential route of 2019-nCoV infection in the urinary system.@*METHODS@#We used both published kidney and bladder cell atlas data and new independent kidney single-cell RNA sequencing data generated in-house to evaluate ACE2 gene expression in all cell types in healthy kidneys and bladders. The Pearson correlation coefficients between ACE2 and all other genes were first generated. Then, genes with r values larger than 0.1 and P values smaller than 0.01 were deemed significant co-expression genes with ACE2.@*RESULTS@#Our results showed the enriched expression of ACE2 in all subtypes of proximal tubule (PT) cells of the kidney. ACE2 expression was found in 5.12%, 5.80%, and 14.38% of the proximal convoluted tubule cells, PT cells, and proximal straight tubule cells, respectively, in three published kidney cell atlas datasets. In addition, ACE2 expression was also confirmed in 12.05%, 6.80%, and 10.20% of cells of the proximal convoluted tubule, PT, and proximal straight tubule, respectively, in our own two healthy kidney samples. For the analysis of public data from three bladder samples, ACE2 expression was low but detectable in bladder epithelial cells. Only 0.25% and 1.28% of intermediate cells and umbrella cells, respectively, had ACE2 expression.@*CONCLUSION@#This study has provided bioinformatics evidence of the potential route of 2019-nCoV infection in the urinary system.

ABSTRACT

Abstract Objective: The aim of this study was to evaluate whether sufentanil can reduce emergence delirium in children undergoing transthoracic device closure of ventricular septal defect (VSD) after sevoflurane-based cardiac anesthesia. Methods: From February 2019 to May 2019, 68 children who underwent transthoracic device closure of VSD at our center were retrospectively analyzed. All patients were divided into two groups: 36 patients in group S, who were given sufentanil and sevoflurane-based cardiac anesthesia, and 32 patients in group F, who were given fentanyl and sevoflurane-based cardiac anesthesia. The following clinical data were recorded: age, sex, body weight, operation time, and bispectral index (BIS). After the children were sent to the intensive care unit (ICU), pediatric anesthesia emergence delirium (PAED) and face, legs, activity, cry, consolability (FLACC) scale scores were also assessed. The incidence of adverse reactions, such as nausea, vomiting, drowsiness and dizziness, was recorded. Results: There was no significant difference in age, sex, body weight, operation time or BIS value between the two groups. Extubation time (min), PEAD score and FLACC scale score in group S were significantly better than those in group F (P<0.05). No serious anesthesia or drug-related side effects occurred. Conclusions: Sufentanil can be safely used in sevoflurane-based fast-track cardiac anesthesia for transthoracic device closure of VSD in children. Compared to fentanyl, sufentanil is more effective in reducing postoperative emergence delirium, with lower analgesia scores and greater comfort.

ABSTRACT

Abstract Objective: To explore the postoperative changes in inflammatory markers in children who underwent device closure of an atrial septal defect (ASD) via a transthoracic or transcatheter approach. Methods: The experimental and clinical data were retrospectively collected and analyzed for a total of 53 pediatric patients between September 2018 and December 2018. According to the different treatments, 19 patients who underwent transthoracic device closure were assigned to group A, and the remaining 34 patients who underwent a transcatheter approach were assigned to group B. Results: All patients were successfully occluded without any device-related severe complication. Compared with the preoperative levels, the postoperative levels of most inflammatory cytokines in both groups were significantly increased and reached a peak on the first day after the procedure. The level of postoperative inflammatory cytokines was significantly lower in group B than in group A. In addition, there was no significant difference in procalcitonin before and after the transcatheter approach. Conclusion: Systemic inflammatory reactions occurred after transthoracic or transcatheter device closure of ASDs in pediatric patients. However, these inflammatory reactions were more significant in patients who underwent a transthoracic approach than in patients who underwent a transcatheter approach.

ABSTRACT

Objective:To investigate the clinical features of encephalocraniocutaneous lipomatosis (ECCL).Methods:The clinical characteristics, imaging manifestations and electroencephalogram changes of five patients with ECCL from Guangdong 999 Brain Hospital between December 2016 and February 2019 were collected and analyzed.Results:All five cases showed ocular, skin and central nervous system anomalies. Corneal anomalies were found in five cases, eyelid coloboma in three cases, calcification of the globe in two cases, and choristoma in one case. All five cases presented with naevus psiloliparis, three cases with small nodular skin tags on eyelids, and three cases with café-au-lait spots on the trunk. Dysplasia of the right cerebral hemisphere was observed in all five cases, four cases with enlargement of the right ventricle, three cases with arachnoid cysts, and one case with dysplasia of the corpus callosum. The onset of the seizures of five cases was found within one year old. Spasms were observed in five cases, partial seizure in three cases, and tonic seizure in one case. Five cases were drug-resistant epilepsy. Seizures decreased significantly after adrenocorticotropic hormone treatment in one case and seizures free after surgery in one case. One case had seizure free by corpus callosotomy, but had a relapse after four months. Three cases used ketogenic diet, including one case with epileptic seizure reduction, one case with development progress. All five cases had developmental delays. The exon gene sequencing of four cases was found normal. KRAS gene mutation was found in brain tissue of one patient.Conclusions:ECCL is a rare clinical disease that often involves the nervous system, skin and eyes. The seizures of the patients are often difficult to control and have development delays. Surgery may be necessary to control the seizures. ECCL is thought to be somatic mutations, which are hard to detect in the blood and can be found in affected tissues.

ABSTRACT

OBJECTIVE:To inve stigate the effects of polymorphism of CYP3A4,CYP3A5 and other genes on the increasing of tacrolimus blood concentration by Wuzhi capsules in renal transplantation patients. METHODS :Totally 194 patients in Han nationality underwent renal transplantation and rece ived outpatient follow-up after surgery were selected from the First Affiliated Hospital of Anhui Medical University during Aug. 2015-Nov. 2018,and then divided into single drug group (107 cases)and combination group (87 cases)according to using of Wuzhi capsules or not. Single drug group was given Tacrolimus capsules 0.1-0.15 mg/kg,po,bid+Mycophenolate mofetil capsule s 0.5-0.75 g,bid or Mycophenolate sodium enteric-coated tablets 360-540 mg,bid+Prednisone acetate tablets 10 mg,qd;combination group was additionally given two Wuzhi capsules ,bid,on the basis of single drug group. Two groups were treated at least 7 d. The clinical data (such as patients ’sex and age )were collected ,and enzyme amplification immunoassay was used to detect steady-state valley concentration of tacrolimus ,and calculate valley concentration/daily dose (C/D)value. PCR was adopted to detect patient genotyping of CYP3A5 gene rs 4646457,rs15524 and rs776746 locus,CYP3A4 gene rs 4646437,rs2242480 and rs 35599367 locus,ABCB1 gene rs 1128503 locus,ABCC2 gene rs3740066 locus,NR1I2 gene rs 3814055 locus,POR gene rs 1057868 locus,PPARA gene rs 4253728 locus,IL-3 gene rs 181781 locus, IL-10 gene rs 1800896 locus,CTLA4 gene rs 4553808 locus,CYP2C19 gene rs 4244285 and rs 4986893 locus,respectively. The correlation of each factor and tacrolimus C/D value was analyzed by Kruskal-Wallis test or Spearman rank test. Multivariate linear regression was conducted. RESULTS :In 194 renal transplanation patients ,only wild type at rs 3599367 locus of CYP3A4 gene and rs4253728 locus of PPARA gene were detected ,and each genotype distribution of other genes was consistent with the Hardy-Weinberg equilibrium (P>0.05). Single factor analysis and multiple linear regression analysis showed that the combination of Wuzhi capsules and rs 776746 polymorphism of CYP3A5 gene were related to tacrolimus C/D value(P<0.05). There was statistical significance in tacrolimus C/D values among different genotypes of CYP3A5 gene in single drug group and combnation group(P<0.05). C/D value of GG and AG genotype in single drug group were significantly lower than combination group (P< 0.05),while there was no statistical significance in tacrolimus C/D value of AA genotype between 2 groups (P>0.05). CONCLUSIONS:Combination of Wuzhi capsules or not and polymorphism of CYP3A5 gene rs 776746 locus are associated with blood concentration of tacrolimus in renal transplantation patients in Han nationality. Combined use of Wuzhi capsules can increase blood concentration of tacrolimus in GG and AG genotype ,but have no significant effect on AA genotype.

ABSTRACT

A capacitively coupled contactless conductivity detector for high performance liquid chromatography was developed. The detector was consisted of a signal generator, a signal amplifier, and a pair of tubular electrodes. A plastic connecting tube following the separation column was threaded through the two tubular electrodes. When the separated components passed the region between two tubular electrodes, they would be sensed. The instrumental parameters of this detector were investigated, including the internal diameter of connecting tube,the frequency and voltage of excitation signal, electrodes length, and the gap between two electrodes. The 0.5 mm of internal diameter of connecting tube, 70 kHz of excitation frequency, 60 V of excitation voltage,10 mm of electrodes length and 1.5 mm of gap between two electrodes were finally found to be the best working conditions for the detector. This HPLC-C4D(capacitively coupled contactless conductivity detector) was applied to the analysis of oleic and linoleic acids in Brucea javanica oil. The chromatographic peak area was linear with concentration for oleic and linoleic acids in 5-1000 μg/mL, and the limit of detection reached 2.5 μg/mL and 1.0 μg/mL,respectively. The results demonstrate that the present method is sensitive and accurate, proving this homemade contactless conductivity detector has a great application potential for pharmaceutical analysis in future development.

ABSTRACT

Objective To investigate the effects of different gargling methods of sodium bicarbonate on oral pH values in children with malignant tumors undergoing chemotherapy, and to provide references for preventing oral fungal infection. Methods Totally 36 children with malignant tumors were recruited as research objects. Gargling methods were designed based on different sodium bicarbonate concentration, rinsing time, rinsing volume, and rinsing bites. Oral pH value was tested by pH indicator strips before and after rinsing. Results Sodium bicarbon-ate solution concentration, rinsing volume, ringing time and rinsing bites all influenced the changes of oral pH val-ue after rinsing. Regardless of methods, oral pH value was restored to the level of pre-rinse after 90 minutes. There were no significant differences in degree of comfort and compliance among different methods. Conclusion For children with malignant tumors undergoing chemotherapy, 5% 15ml sodium bicarbonate gargle is recommended to be rinsed for 30 seconds with 3 mouthfuls, and the interval is recommended to be no more than 90 minutes.

ABSTRACT

Objective To discuss the methods of the heat preservation performance monitoring of the blood transport case and to provide the technical support for the safety of blood transportation.Methods At the different environment temperature,the amount of the cold resource was decided by the mass ratio of cold resource to blood and the temperature was automatically recorded by the intelligent temperature chip continuously,to monitor the changes of each monitoring point in the blood transport case.Results When the mass ratio of cold resource to blood was fixed at 1∶6,the cold chain of the blood transport case could keep the tempera-ture of 2-10 ℃ for 8 hours at the environment temperature of 12 ℃,It could keep the temperature of 2-10 ℃ for 4.5 hours at the environment temperature of 25 ℃,and it could keep the temperature of 2-10 ℃ for 2 hours at the environment temperature of 44℃.Conclusion When the mass ratio of cold resource to blood is fixed,as the environment temperature changes,the available time that the blood transport case keeps with the cold-chain requirement varies according to the results of the heat preservation per-formance monitoring of the blood transport case.
