ABSTRACT

OBJECTIVES@#To study the clinical features and chemotherapy response of Burkitt's lymphoma (BL) in children and the influence of rituximab on the prognosis of children with BL.@*METHODS@#A retrospective analysis was performed for the medical data of 62 children with BL, including clinical features, therapeutic efficacy, and prognostic factors. The Cox regression model was used to identify the factors associated with poor prognosis in children with BL. According to whether rituximab was used, the children with advanced (stage III/IV) BL were divided into two groups: chemotherapy plus rituximab and chemotherapy alone. The prognosis was compared between the two groups.@*RESULTS@#For these 62 children, the median age of onset was 5 years (range 1-14 years), and there were 58 boys (94%) and 4 girls (6%). The primary site was abdominal cavity in 41 children (66%), and head and neck in 16 children (26%). There were 1 child with stage I BL (2%), 8 with stage II BL (13%), 33 with stage III BL (53%), and 20 with stage IV BL (32%). The median follow-up time was 29 months, with progression/recurrence observed in 15 children (24%), and the 3-year overall survival (OS) rate and event-free survival (EFS) rate were 82.8%±5.2% and 77.3%±5.8%, respectively. For the children with stage III/IV BL, there was a significant difference in the 3-year the OS rate between the chemotherapy plus rituximab group (16 children) and the chemotherapy alone group (30 children) (93.3%±6.4% vs 65.6%±9.9%, P=0.042), while there was no significant difference in the 3-year EFS rate between the two groups (86.2%±9.1% vs 61.8%±10.1%, P>0.05). The Cox regression analysis showed that central nervous system involvement, lactate dehydrogenase >1 000 U/L, and early incomplete remission were the factors associated with poor prognosis (P<0.05).@*CONCLUSIONS@#Chemotherapy combined with rituximab can improve the prognosis of children with stage III/IV BL. Central nervous system involvement, elevated lactate dehydrogenase level, and early incomplete remission may indicate a poor prognosis in children with BL.

ABSTRACT

OBJECTIVES@#To study the association of fractional exhaled nitric oxide (FeNO) and nasal nitric oxide (nNO) with asthma control and their value in the diagnosis of allergic rhinitis in children.@*METHODS@#A total of 186 children aged 5-12 years, who attended the outpatient service of the Department of Respiration, Shanghai Children's Hospital due to bronchial asthma and/or allergic rhinitis or who underwent physical examination, were enrolled as subjects, with 52 children in the asthma group, 60 children in the asthma+allergic rhinitis group, 36 children in the allergic rhinitis group, and 38 children in the control group. FeNO, nNO, and pulmonary function were compared between groups.@*RESULTS@#The asthma+allergic rhinitis, asthma, and allergic rhinitis groups had a significantly higher level of FeNO than the control group (P<0.05). The asthma+allergic rhinitis and allergic rhinitis groups had a significantly higher level of nNO than the asthma and control groups (P<0.05). The uncontrolled asthma and partially controlled asthma groups had significantly higher levels of FeNO and nNO than the completely controlled asthma group (P<0.05). The receiver operating characteristic (ROC) curve analysis showed that nNO had an area under the ROC curve of 0.91, with a sensitivity of 80.0% and a specificity of 89.5% in the diagnosis of allergic rhinitis in children with asthma (P<0.05).@*CONCLUSIONS@#The combined measurement of nNO and FeNO can be used to evaluate the control of asthma, and the measurement of nNO can help with the diagnosis of allergic rhinitis in children with bronchial asthma.

ABSTRACT

The CRISPR/Cas9 based prime editing (PE) technique enables all 12 types of base substitutions and precise small DNA deletions or insertions without generating DNA double-strand breaks. Prime editing has been successfully applied in plants and plays important roles in plant precision breeding. Although plant prime editing (PPE) can substantially expand the scope and capabilities of precise genome editing in plants, its editing efficiency still needs to be further improved. Here, we review the development of PPE technique, and introduce structural composition, advantages and limitations of PPE. Strategies to improve the PPE editing efficiency, including the Tm-directed PBS length design, the RT template length, the dual-pegRNA strategy, the PlantPegDesigner website, and the strategies for optimizing the target proteins of PPE, were highlighted. Finally, the prospects of future development and application of PPE were discussed.

ABSTRACT

Objective@#This cross-sectional study aimed to investigate the characteristics of malocclusions in scoliotic patients through clinical examinations. @*Methods@#Fifty-eight patients with idiopathic scoliosis (IS) and 48 patients with congenital scoliosis (CS) participated in the study. A randomly selected group of 152 orthopedically healthy children served as the control group. Standardized orthodontic and orthopedic examination protocols were used to record the occlusal patterns and type of scoliosis. Assessments were made by three experienced orthodontists and a spinal surgery team. The differences in the frequency distribution of occlusal patterns were evaluated by the chi-squared test. @*Results@#In comparison with patients showing IS, patients with CS showed a higher incidence of Cobb angle ≥ 45° (p = 0.020) and included a higher proportion of patients receiving surgical treatments (p < 0.001). The distribution of the Angle Class II subgroup was significantly higher in the IS (p < 0.001) and CS (p = 0.031) groups than in the control group. In comparison with the healthy controls, the CS and IS groups showed significantly higher (p < 0.05) frequencies of asymmetric molar and asymmetric canine relationships, upper and lower middle line deviations, anterior deep overbite, unilateral posterior crossbite, and canted occlusal plane, with the frequencies being especially higher in CS patients and to a lesser extent in IS patients. @*Conclusions@#Patients with scoliosis showed a high frequency of malocclusions, which were most obvious in patients with CS.

ABSTRACT

Objective: To investigate the effect and its underlying molecular mechanisms of essential oil from Saussurea costus in esophageal cancer cell line Eca109. Methods: The chemical composition of essential oil from Saussurea costus was investigated by gas chromatography-mass spectrometry (GC-MS). The anti-proliferative, anti-migrative, and apoptotic effects of essential oil from Saussurea costus against Eca109 cells were analyzed. Moreover, the expression of proteins associated with cell cycle, metastasis, and apoptosis was determined. Results: GC-MS analysis showed that essential oil from Saussurea costus was predominantly comprised of sesquiterpenes. Saussurea costus essential oil inhibited the viability of Eca109 cells in a dose-and time-dependent manner with IC 50 values of (24.29±1.49), (19.16±2.27) and (6.97±0.86) μg/mL at 12, 24, and 48 h, respectively. The expression levels of target proteins in the cell cycle (phase G 1 /S), including cyclin D1, p21, and p53, were affected by Saussurea costus essential oil. The essential oil also downregulated the expression of metastasis-related proteins MMP-9 and MMP-2. Moreover, it induced apoptosis of Eca109 cells through the mitochondrial pathway, as well as inhibition of STAT3 phosphorylation. Conclusions: The essential oil from Saussurea costus exhibited anti-proliferative, anti-migrative, and apoptotic effects on Eca109 cells, and could be further explored as a potential anti-esophageal cancer agent.

ABSTRACT

ObjectiveTo study on the correlation between the apparent color, near-infrared spectroscopy and dynamic changes of index constituent content of samples during the processing of steamed Notoginseng Radix et Rhizoma, and to provide reference for the processing process optimization and quality control of this decoction piece. MethodSamples were dried and crushed by setting three steaming temperature gradients of 100-105, 114-118, 130-136 ℃, and sampled at steaming times of 1, 2, 4, 8, 12, 24 h, respectively. The effects of different steaming temperatures and times on the color and absorption of steamed Notoginseng Radix et Rhizoma at different infrared wavelengths were observed, and principal component analysis and cluster analysis were performed on the obtained data by R 4.1.0 and SPSS 21.0 software to observe the changes in color and infrared absorption characteristics of samples. High performance liquid chromatography (HPLC) was employed to determine the content changes of notoginsenoside R1, ginsenoside Rg1, ginsenoside Rb1, ginsenoside Re, 20(S)-ginsenoside Rg3 and 20(R)-ginsenoside Rg3 before and after steaming of Notoginseng Radix et Rhizoma, mobile phase was acetonitrile (A)-water (B) for gradient elution (0-30 min, 19%A; 30-60 min, 19%-44%A; 60-78 min, 44%-74%A; 78-80 min, 74%-100%A; 80-86 min, 100%A; 86-87 min, 100%-19%A; 87-95 min, 19%A) with the detection wavelength of 203 nm. ResultDuring the steaming process of Notoginseng Radix et Rhizoma, with the increase of steaming temperature and time, the b* (yellow-blue value), L* (brightness), △E* (comprehensive color difference value) of sample powder showed a decreasing trend, while the a* (red-green value) showed an increasing trend, and the color gradually deepened from gray to brown and dark black. There was no significant difference in the infrared absorption between raw and steamed Notoginseng Radix et Rhizoma sample powder in the low and medium wavelength bands, but significant difference in the infrared absorption of high band, especially in the band of 9 600-10 000 cm-1. HPLC showed that the contents of the original components (notoginsenoside R1, ginsenoside Rg1, Re and Rb1) decreased and 20(S)-ginsenoside Rg3 and 20(R)-ginsenoside Rg3 were newly produced after steaming of Notoginseng Radix et Rhizoma. The content proportion of these six index components reached the best when the steaming temperature at 130-136 ℃ and the steaming time of 1 h. ConclusionThe color and infrared absorption of samples are affected by the dynamic changes of chemical composition during the steaming process, and the composition change is the result of the joint influence of steaming temperature and time. In this paper, through multi-dimensional analysis of the apparent color indexes, the change pattern of near-infrared absorption characteristics and the index components of the samples, the different process parameters of steamed Notoginseng Radix et Rhizoma were evaluated holistically, and the quality transfer pattern of its processing process was initially revealed, which can provide scientific basis for processing optimization and quality evaluation of steamed Notoginseng Radix et Rhizoma.

ABSTRACT

This study aimed to investigate the neurotoxicity induced by trichloroacetic acid (TCA) and the possible protective mechanisms of boron (B). Mouse BV2 cells were treated with TCA (0, 0.39, 0.78, 1.56, 3.12, 6.25, or 12.5 mmol/L) and B (0, 7.8, 15.6, 31.25, 62.5, 125, 500, or 1,000 mmol/L) for 3 h and 24 h, respectively. Then, reactive oxygen species, and supernatant proinflammatory cytokine and protein levels were analyzed after 24 h of combined exposure. Beyond the dose-dependent decrease in the cellular viability, it clearly increased after B supplementation ( P < 0.05). Moreover, B decreased oxidative damage, and significantly down-regulated IL-6 levels and up-regulated TNF-β production ( P < 0.05). B also decreased apoptosis via the p53 pathway. The present findings indicated that TCA may induce oxidative damage, whereas B mitigates these adverse effects by decreasing cell apoptosis.

ABSTRACT

Objective: To clarify the chemotactic characteristics of type 2 helper T cells (Th2 cells) and type 2 follicular helper T cells (Tfh2 cells) in peripheral blood of patients with allergic rhinitis (AR), and to explore the associations between the chemokine receptors expression and the levels of antigen-specific IgE (sIgE) and the severity of the disease. Methods: The peripheral blood mononuclear cells of 41 patients with AR (20 males and 21 females, aged 35.0 (24.5, 47.0) years) and 42 healthy controls (24 males and 18 females, aged 35.0 (24.8, 46.5) years) treated in Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology from April 2017 to February 2018 were isolated. The expressions of chemokine receptor (CCR)2, CCR3, CCR4, CCR5, CCR7, CCR8, chemokine C-X3-C-motif receptor 1 (CX3CR1) and C-X-C motif receptor 4 (CXCR4) in Th2 and Tfh2 cells were explored by fluorescence activated cell sorting (FACs). The relationship between the expression of these chemokine receptors in Th2 cells and Tfh2 cells and the levels of serum sIgE and the scores of visual analogue scale (VAS) was analyzed. Graphpad prism 7.0 software was used for statistical analysis. Results: The significant differences in chemotactic characteristics between Th2 cells and Tfh2 cells in the control group were found: Th2 cells highly expressed chemokine receptors CCR2, CCR3, CCR5, CCR8 and CX3CR1, while Tfh2 cells highly expressed immune cell homing chemokine receptors CCR7 and CXCR4. AR patients, compared to the control, expressed higher levels of CCR2, CCR5 and CX3CR1 on peripheral Th2 cells(all P<0.01). At the same time, the proportion of CCR2+and CCR5+Th2 cells was positively correlated with VAS score (r value was 0.58 and 0.61, respectively, both P<0.01). In AR patients, higher expression levels of CCR7 on Tfh2 cells were detected (P<0.01), and the proportion of CCR7+Tfh2 cells was positively correlated with the level of serum sIgE (r=0.51, P<0.01). Conclusion: The percentage of CCR2+ and CCR5+ Th2 cells in peripheral of AR patients can reflect the severity of AR to some extent, while the percentage of CCR7+ Tfh2 cells is positively correlated with the level of serum sIgE.

ABSTRACT

Objective: To explore the composition of intestinal microflora prior to onset of necrotizing enterocolitis (NEC) in very low birth weight preterm infants. Methods: This was a multicenter prospective nested case-control study. A total of 46 very low birth weight preterm infants (birth weight <1 500 g and gestional age <35 weeks) within 24 h of life admitted into Neonatal Intensive Care Unit of Children's Hospital of Soochow University and Suzhou Municipal Hospital from April 20 to November 20, 2018 were enrolled. Baseline clinical data and fecal samples of these infants were collected. The subsequent sampling time points were 1st, 4th and 7th day in the first week of life then once per week consecutively. The endpoint of sampling was NEC occurrence, patient discharge or the 8th week post-discharge, whichever came first. Fecal samples were analyzed by 16 S rDNA high-throughput nucleotide sequencing. The control cases were infants without NEC who were matched to the NEC cases with a ratio of 1∶1. The operational taxonomic units (OTU), sequence number and shannon diversity index of the fecal samples were analyzed. Continuous variables were compared with t-test or non-parametric test, and χ2 test or Fisher's exact test was used for categorical variables. Results: There were 23 patients in each group. The gestational age was (29.4±1.8) weeks in NEC group and (29.9±1.6) weeks in control group, including 13 males (57%) and 11 males (48%) in each group, respectively. Species abundance showed that the Firmicutes in both groups decreased temporarily at 7 days of age and then increased with age in control group, but not in NEC group, the Proteobacteria in both groups increased at 7 days of age and then decreased in control group, but kept increasing in NEC group. Regarding the other levels of taxonomy, compared with that of the control group, the NEC group had lower abundance of Proteobacteria, γ-proteobacteria and Enterobacteriaceae at 7 days of age, while higer abundance of Faecalibacterium at 14 days of age, meanwhile, lower Clostridium and Streptococcus at 21 days of age, lower Firmicutes, Clostridia and Clostridium perfringens and higher Proteobacteria and γ-proteobacteria at 28 days of age, these differences were all statistically significant (U=43.00, 43.00, 45.00, 80.00, 74.00, 76.00, 19.00, 8.00, 36.00, 25.00, 25.00,all P<0.05). The shannon index of NEC group was both lower than that of the controls at 21 days of age (2.4 (1.4, 3.0) vs. 3.1 (2.6, 4.0), U=67.00, P=0.027) and 28 days of age (2.4 (1.4, 2.8) vs. 3.9 (3.3, 4.2), U=12.00, P=0.001). Conclusions: The intestinal microflora profile of very low birth weight preterm infants has already changed prior to NEC development. The emergence of differential flora and the reduction of microflora diversity may facilitate early identification and prevention of NEC.

ABSTRACT

Objective To explore the clinical efficacy and safety of the omalizumab treatment in children with high level IgE allergic asthma. Methods The clinical data of 2 children with allergic asthma treated with omalizumab in the Departemnt of Respiratory Medicine of Shanghai Children’s Hospital from August 2020 to May 2021 were retrospectively analyzed, and they had regular follow-up after end of treatment. The dosage and course of treatment, therapeutic effect and adverse drug reactions of omalizumab were analyzed. Results After receiving omalizumab treatment, asthma symptoms were well controlled, the dosage of inhaled corticosteroids during asthma treatment were reduced and nasal symptoms were relieved. 20 subcutaneous injections were received by 2 children, and no adverse reactions were found. After the treatment, regular pharmaceutical follow-up showed that the children were in good health. Conclusion Omalizumab is suitable for high level IgE allergic asthma and can improve asthma control symptoms with good long-term safety. However, the appropriate dosage and course of treatment still need further experience accumulation.

ABSTRACT

Objective:To investigate the perioperative risk factors in contribution of hyperbilirubinemia following cardiopulmonary bypass(CPB) assisted cardiovascular surgery, of which cutoff values of key factors are defined.Methods:1 286 patients received cardiac surgery assisted by CPB from January 2017 to March 2019 were included in the study. The perioperative data and the peak serum total bilirubin at selected timepoints were recorded. Logistic regression of multi-factor analysis was used to define risk factors and then broken-line analysis was applied to predict the risky threshold. Results:312(24.26%)patients developed hyperbilirubinemia after surgery, with the in-hospital mortality rate up to 34.62%(108 cases). In those patients, valve surgery(45.51%, 142/312), great vessel open surgery(37.82%, 118/312) and heart transplantation(7.69%, 24/312) were mostly performed. The duration of postoperative ICU stay and the use of ventilation were 6 days and 68 hours, which were significantly higher than those in non-hyperbilirubinemia group( P<0.01). Multivariate logistic regression showed that the postoperative ventilation time>49 h, the cardiopulmonary bypass(CPB) time>181 min and the abnormal preoperative liver function, use of intra-aortic balloon pump and extracorporeal membrane oxygen, unplanned re-exploration for bleeding were the risk factors for postoperative hyperbilirubinemia( P<0.01). The cutoff duration of postoperative mechanical ventilation and CPB affecting the incidence of hyperbilirubinemia, ICU days and in-hospital mortality were 120.21 h and 143.26 min, 248.20 h and 239.51 min, 259.50 h and 190.60 min, respectively. Conclusion:Preoperative abnormal liver function, intraoperative CPB time, postoperative mechanical ventilation time, postoperative use of IABP or ECMO assistance, and unplanned secondary thoracotomy were high-risk factors for hyperbilirubinemia after CPB-assisted cardiovascular surgery.

ABSTRACT

Objective:To assess the change and inter-individual variation in body temperature and analyze related variables among Chinese adults.Methods:Data of of 9 184 participants[mean age(52.38±14.69) years, 4 350 men and 4 834 women] were obtained from the China Health and Nutrition Survey(CHNS) 2015. Descriptive statistics and liner regression models were deployed in the analysis.Results:Overall, the mean normal axillary body temperature was 36.43℃, higher temperature was observed in men(0.032℃, P<0.001) than women. Using the multivariate linear regression model, it was revealed that age, region, territory, season, height, and hip circumference were significantly associated with body temperature. Higher individual temperature was observed in urban(0.028℃) than rural, in southern(0.040℃) than northern, and in winter(0.054℃) than autumn. Body temperature was also negatively associated with age(-0.001℃ per year), hip circumference(-0.001℃ per cm), but is positively associated with height(0.003℃ per cm). With other variables controlled, body temperature was related to whether there is myocardial infarction(ever vs never 0.187℃). Conclusion:In China, the current normal body temperature is lower than that established in 19th century(37℃), and body temperature is related to several factors. When screening and diagnosing a disease, inter-individual variance should be fully considered.

ABSTRACT

Objective:To explore independent risk factors and risk stratification for diagnosis of clinically significant prostate cancer (CsPCa) in biopsy-naive patients with nonsuspicious multiparametric magnetic resonance imaging (mpMRI).Methods:The data of 549 patients who underwent initial systematic biopsy (SB) in the First Affiliated Hospital of Soochow University, the Second Affiliated Hospital of Soochow University and Traditional Chinese Medicine Hospital of Kunshan between October 2015 and January 2021 were retrospectively reviewed. Nonsuspicious mpMRI was defined as Prostate Imaging-Reporting and Data System (PI-RADS)≤2. All patients received systematic 12 core prostate biopsy, 278 of them by transperineal and 271 by transrectal biopsies. The median age of the patients was 67 (62, 73) years, the median prostate specific antigen (PSA) was 9.01 (6.15, 13.64) ng/ml, the median prostate volume was 48.41 (35.85, 64.28) ml, and 54 patients were positive in digital rectal examination (DRE). Taking CsPCa as the outcome index, receiver operating characteristic (ROC) analysis was performed on age, tPSA, f/tPSA and PSA density (PSAD) to obtain the optimal cut-off value, and logistics regression was used to explore the independent risk factor of CsPCa in mpMRI negative patients. The optimal cut-off value when the negative predictive value (NPV) of mpMRI diagnosis of CsPCa was 100%, was taken as the protective factor, and the risk stratification model was finally proposed.Results:Of all 549 cases, 44 were CsPCa, 35 were clinically insignificant prostate cancer and 470 were non-prostate cancer. There were significant differences in age (71 vs. 67 years old), tPSA (11.95 vs. 8.75 ng/ml), PSAD [0.31 vs. 0.18 ng/(ml·cm 3)], f/tPSA (0.12 vs. 0.16) and DRE positive rate (38.6% vs. 7.3%) between CsPCa group and non-CsPCa group ( P<0.01). Cut-off values were taken in ROC analysis when the Youden index was at its maximum. The optimal cut-off values of each continuous variable were: age=65 years, tPSA=10ng/ml, f/tPSA=0.2 and PSAD=0.15 ng/(ml·cm 3). Multivariate analysis showed that ages over 65 years ( OR=3.43, 95% CI 1.55-7.58, P=0.002), f/t PSA ratio<0.2 ( OR=3.84, 95% CI 1.28-11.56, P=0.016), PSAD>0.15 ng/(ml·cm 3) ( OR=3.60, 95% CI 1.13-11.51, P=0.03) and positive DRE ( OR=5.20, 95% CI 2.39-11.32, P<0.001) were independent risk factors of CsPCa. When NPV was 100%, the cut-off values were taken as the protective factors: age≤55 years, f/tPSA≥0.3, PSAD≤0.1 ng/(ml·cm 3). Combined with independent risk factors, preliminary risk stratification was conducted: those with ≥2 high risk factors were considered as high risk group, those with ≥2 protective factors were considered as low risk group, and the middle region was considered as medium risk group. Conclusions:Patients with age>65 years, f/tPSA<0.2, PSAD > 0.15 ng/(ml·cm 3) and DRE positive are independent risk factors of CsPCa in mpMRI negative patients. Patients in the high-risk group were recommended to undergo prostate biopsy, while patients in the low-risk group could be considered to avoid biopsy.

ABSTRACT

Objective:To analyze the influencing factors of anesthesia recovery time after gastric cancer surgery in patients with type 2 diabetes mellitus (T2DM), and establish a nomogram model.Methods:The clinical data of 120 T2DM patients underwent open surgery for gastric cancer from February 2020 to January 2021 in Handan Central Hospital were retrospectively analyzed. Among them, 50 patients had an anesthesia recovery time>30 min (observation group), and 70 patients had an anesthesia recovery time≤30 min (control group). Multivariate Logistic regression was used to analyze the independent risk factors of anesthesia recovery time after gastric cancer surgery in patients with T2DM. Receiver operating characteristic (ROC) curve was drawn to analyze the optimal cut-off value of each influencing factor for predicting anesthesia recovery time after gastric cancer surgery in patients with T2DM. A nomogram model to predict anesthesia recovery time after gastric cancer surgery in patients with T2DM was established with R language software 4.0 "rms" package.Results:The proportion of men, age, decrease amplitude of postoperative temperature, operation time intraoperative blood transfusion rate in observation group were significantly higher than those in control group: 84.00% (42/50) vs. 20.00% (14/70), (60.31 ± 14.23) years vs. (47.58 ± 8.96) years, (0.33 ± 0.09) ℃ vs. (0.28 ± 0.08) ℃, (92.32 ± 8.58) min vs. (84.54 ± 6.24) min and 38.00% (19/50) vs. 10.00% (7/70), the body mass index (BMI), heart rate and operating room temperature were significantly lower than those in control group: (20.11 ± 3.96) kg/m 2 vs. (24.69 ± 4.58) kg/m 2, (103.73 ± 9.57) beats/min vs. (118.32 ± 18.15) beats/min and (28.66 ± 1.58) ℃ vs. (30.25 ± 1.98) ℃, and there were statistical differences ( P<0.01); there were no statistical differences in smoking, drinking, hypertension, hyperlipidemia, coronary heart disease, anesthetic drug types, anesthesiologist job title, muscle relaxant drug types and body temperature between 2 groups ( P>0.05). ROC curve analysis results showed that the optimal cut-off values of age, BMI, heart rate, decrease amplitude of postoperative temperature, operating room temperature and operation time for predicting anesthesia recovery time after gastric cancer surgery in patients with T2DM were 46 years old, 21.8 kg/m 2, 113 beats/min, 0.3 ℃, 30.6 ℃ and 91 min, respectively. Multivariate Logistic regression analysis results showed that gender (male), age (>46 years old), BMI (≤21.8 kg/m 2), decrease amplitude of postoperative temperature (>0.3 ℃), operating room temperature (≤30.6 ℃) and operation time (>91 min) were independent risk factors for predicting anesthesia recovery time after gastric cancer surgery in patients with T2DM ( OR = 1.909, 1.815, 1.606, 1.458, 1.521 and 1.539; 95% CI 1.215 to 3.000, 1.014 to 3.249, 1.252 to 1.941, 1.251 to 1.628, 1.068 to 2.167 and 1.119 to 1.828; P<0.01 or<0.05). When gender, age, BMI, decrease amplitude of postoperative temperature, operating room temperature and operation time were included as predictors for constructing the nomogram model, the internal validation results showed that the c-index of the nomogram model for predicting anesthesia recovery time after gastric cancer surgery in patients with T2DM was 0.701 (95% CI 0.672 to 0.724); calibration curve showed good agreement between observed value and predicted value; the threshold value of the nomogram model for predicting anesthesia recovery time after gastric cancer surgery in patients with T2DM was>0.20, and the nomogram model provided a net clinical benefit; the clinical net benefit of the nomogram model was greater than that of sex, age, BMI, decrease amplitude of postoperative temperature, operating room temperature and operation time. Conclusions:A nomogram model to predict anesthesia recovery time after gastric cancer surgery in patients with T2DM is constructed based on gender, age, BMI, decrease amplitude of postoperative temperature, operating room temperature and operation time, and this model is significant for predicting anesthesia recovery time after gastric cancer surgery in patients with T2DM.

ABSTRACT

Objective:To investigate the prognosis of robotic pancreatoduodenectomy after the learning curve and open pancreatoduodenectomy for pancreatic cancer.Methods:The propensity score matching and retrospective cohort study was conducted. The clinicopathological data of 396 patients who underwent curative pancreatoduodenectomy for pancreatic duct adenocar-cinoma in Ruijin Hospital of Shanghai Jiaotong University School of Medicine from January 2017 to December 2018 were collected. There were 244 males and 152 females, aged 64(range, 36?92)years. Of 396 patients, 86 cases undergoing robotic pancreatoduodenectomy were divided into robotic group, 310 cases undergoing open pancreatoduodenectomy were divided into open group. Observa-tion indicators: (1) propensity score matching and comparison of general data between the two groups after matching; (2) follow-up and survival analysis. Follow-up was conducted by telephone interview or outpatient examinations including tumor markers and abdominal imaging examina-tions to detect survival of patients up to March 2022. Overall survival was defined as the time from the surgery date to death or the last follow-up. Disease-free survival was defined as the time from the surgery date to tumor recurrence or the last follow-up. The propensity score matching was conducted by 1∶1 matching using the nearest neighbor method. Normality of measurement data was examined using the Shapiro-Wilk test. Measurement data with skewed distribution were described as M(range), and comparison between groups was analyzed using the Mann-Whitney rank-sum test. Count data were represented as absolute numbers, and comparison between groups was analyzed using the chi-square test. Kaplan-Meier method was used to calculate survival rates and draw survival curves, and Log-Rank test was used for survival analysis. An intent-to-treat analysis was performed in this study, patients who were converted to laparotomy from robotic surgery were still divided into the robotic group. Results:(1) Propensity score matching and comparison of general data between the two groups after matching: 164 of 396 patients had successful matching, including 82 cases in robotic group and open group, respectively. Before propensity score matching, the body mass index, cases in stage T1, T2, T3, T4, cases in N0, N1, N2 were 23.4(range, 21.4?25.3)kg/m 2,24, 41, 10, 11, 52, 27, 7 for the robotic group, versus 22.4(range,20.3?23.9)kg/m 2,57, 144, 22, 87, 131, 132, 47 for the open group, showing significant differences in the above indicators between the two groups ( Z=3.01, 2.63, 3.03, P<0.05). After propensity score matching, cases of males, age, body mass index, cases with American Society of Anesthesiologists (ASA) score as 1, 2, 3, CA19-9, cases with preoperative biliary drainage, cases with portal vein resection, cases with pancreatic resection margin <1 mm, cases in stage T1, T2, T3, T4, cases in stage N0, N1, N2, cases with nerve invasion, cases with tumor differentiation as high-medium differentiation, medium-low differentiation, low differentiation, cases with adjuvant chemotherapy were 51, 65(range, 59?69)years, 23.0(range, 21.0?25.2)kg/m 2, 32, 41, 9, 160.4(range, 46.7?377.2)U/mL, 21, 9, 8, 21, 40, 10, 11, 48, 27, 7, 76, 26, 47, 9, 53 for the robotic group, versus 58, 65(range, 58?69)years, 23.3(range, 21.4?25.3)kg/m 2, 35, 39, 8, 172.0(range, 69.7?402.9)U/mL, 26, 9, 10, 24, 40, 7, 11, 49, 28, 5, 76, 22, 49, 11, 57 for the open group, showing no significant difference in the above indicators between the two groups ( χ2=1.34, Z=0.18, 0.34, 0.49, 0.51, χ2=0.75, 0.00,0.25, Z=0.59, 0.27, χ2=0.00, Z=0.76, χ2=0.44, P>0.05). (2) Follow-up and survival analysis: after propensity score matching, 164 patients were followed up for 54(range, 1?67)months. The follow-up time of patients was 55(range, 51?59)months for the robotic group, versus 54(range, 50?58)months for the open group, respectively, showing no significant difference between the two groups ( Z=0.48, P>0.05). During the follow-up, the 1-year overall survival rate, 3-year overall survival rate, the median survival time, 1-year disease-free survival rate, 3-year disease-free survival rate, the median disease-free survival time, tumor recurrence rate, cases with recurrence pattern as local recurrence, liver recurrence, other distant recurrence, local and distant recurrence were 81.7%, 39.0%, 27 months(95% confidence interval as 19?33 months), 61.0%, 34.2%, 15 months(95% confidence interval as 12?18 months), 54.9%(45/82), 12, 16, 9, 8 for the robotic group. The above indicators were 79.3%, 36.0%, 24 months(95% confidence interval as 19?31 months), 59.8%, 27.5%, 15 months(95% confidence interval as 10?20 months), 58.5% (48/82), 10, 22, 6, 10 for the open group. There was no significant difference in overall survival or disease-free survival between the two groups ( χ2=0.39, 0.47, P>0.05). There was no significant difference in tumor recurrence rate or tumor recurrence site between the two groups either ( χ2=0.22, 1.86, P>0.05). Conclusion:After the learning curve, robotic pancreato-duodenectomy has non-inferior prognosis compared with open pancreatoduodenectomy.

ABSTRACT

BACKGROUND@#Coronavirus disease 2019 (COVID-19) has become a worldwide life-threatening pandemic. Lianhua Qingwen is believed to possess the ability to treat or significantly improve the symptoms of COVID-19. These claims make it important to systematically evaluate the effects of using Lianhua Qingwen with Western medicine to treat COVID-19.@*OBJECTIVE@#To evaluate the safety and efficacy of combination therapy, employing Lianhua Qingwen with Western medicine, to treat COVID-19, using a meta-analysis approach.@*SEARCH STRATEGY@#China National Knowledge Infrastructure, Wanfang Database, VIP Database, PubMed, Embase, and Cochrane Library databases were searched for studies evaluating the effect of Lianhua Qingwen-Western medicine combination therapy in the treatment of COVID-19.@*INCLUSION CRITERIA@#(1) Research object: hospitalized patients meeting the diagnostic criteria of COVID-19 were included. (2) Intervention measures: patients in the treatment group received Lianhua Qingwen treatment combined with Western medicine, while the control group received either Western medicine or Chinese medicine treatment. (3) Research type: randomized controlled trials and retrospective study were included.@*DATA EXTRACTION AND ANALYSIS@#Two researchers extracted the first author, the proportion of males and females, age, body temperature, course of treatment, rate of disappearance of main symptoms, duration of fever, adverse reactions, and total effectiveness from the literature. Odds ratio (OR) and 95% confidence interval (CI) were used as the effect value for count data, and mean difference (MD) and 95% CI were used as the effect value for measurement data.@*RESULTS@#Six articles met the inclusion criteria, including a total of 856 COVID-19 patients. The meta-analysis showed that Lianhua Qingwen combination therapy achieved higher rates of fever reduction (OR = 3.43, 95% CI [1.78, 6.59], P = 0.0002), cough reduction (OR = 3.39, 95% CI [1.85, 6.23], P < 0.0001), recovery from shortness of breath (OR = 10.62, 95% CI [3.71, 30.40], P < 0.0001) and recovery from fatigue (OR = 2.82, 95% CI [1.44, 5.53], P = 0.003), higher total effectiveness rate (OR = 2.51, 95% CI [1.73, 3.64], P < 0.00001), and shorter time to recovery from fever (MD = -1.00, 95% CI [-1.04, 0.96], P < 0.00001), and did not increase the adverse reaction rate (OR = 0.65, 95% CI [0.42, 1.01], P = 0.06), compared to the single medication control.@*CONCLUSION@#The Lianhua Qingwen and Western medicine combination therapy is highly effective for COVID-19 patients and has good clinical safety. As only a small number of studies and patients were included in this review, more high-quality, multicenter, large-sample-size, randomized, double-blind, controlled trials are still needed for verification.

ABSTRACT

Objective@#The purpose of this study is to explore the interactive correlations and the influence of physical activity and motor skills on physical condition of adolescents, in order to provide a theoretical basis for adolescent s physical fitness promotion.@*Methods@#Random cluster sampling method was used to select 164 adolescents aged 12-14. The development of motor skills was measured by MABC 2(Movement Assessment Battery for Children 2), and physical activity was measured by ActiGraph GT3X+ type accelerometer. Physical fitness test selected "Chinese National Students Physical Fitness Standard(CNSPFS)" (for middle school students) in the 1 000/800 meters run, standing long jump and sitting forward flexion. Pearson correlation was used to analyze the correlations among physical activity, motor skills and physical fitness, and multiple stepwise regression was used to analyze the influence of physical activity and motor skills on physical fitness.@*Results@#There was a low degree of positive correlation between physical activity and physical condition( r=0.24-0.30, P <0.05); There was a low to moderate positive correlation between motor skills and physical condition( r=0.21-0.42, P <0.05). Physical activity and BMI could explain for 31% of cardiorespiratory endurance. Physical activity, object control and BMI could explain for 26% of muscle strength, balance skills could explain for 5% of flexibility.@*Conclusion@#There is a low to moderate correlation between physical activity, motor skills and physical fitness. Physical activity and motors skills are associated with adolescent s physical fitness level. Comprehensive interventions that promote the development of motor skills and participation in physical activity have practical significance for improving adolescents physical fitness.

ABSTRACT

Objective:To investigate the expression of miR-211-5p in peripheral blood of patients with myelosuppression after neoadjuvant chemotherapy for breast cancer and its effect on Notch signaling pathway by targeting cyclooxygenase 2 (COX2) gene Regulation mechanism.Methods:From Jan. 2018 to Jan. 2021, 185 breast cancer patients who received neoadjuvant chemotherapy in Linyi People’s Hospital for the first time were included as the research objects. Quantitative real-time polymerase chain reaction (qRT-PCR) was used to measure the mRNA expression levels of miR-211-5p, COX2 gene and Notch signaling pathway related genes (Notch1, Jagged1 and Hes1) . The miR-211-5p mimic, inhibitor, mimic NC, and inhibitor NC were transfected into SD rat bone marrow mesenchymal stem cells, and the mRNA expression of miR-10a-3p and COX2 genes was detected by qRT-PCR for 48 hours. Western blot method was used to detect the protein expression levels of Notch signaling pathway related genes.Results:The relative expression of miR-211-5p in patients with severe myelosuppression was 2.41±0.32, which was significantly higher than that in patients with mild myelosuppression (1.53±0.18) ( t=6.385, P<0.001) ; The relative expression of COX2 gene mRNA in patients with severe myelosuppression was 3.64±0.74, which was significantly lower than that in patients with mild myelosuppression (5.37±1.02) ( t=7.469, P<0.001) . In patients with severe myelosuppression, there was a significant negative correlation between miR-211-5p and COX2 gene mRNA levels ( r=-0.694, P=0.006) . The results of the dual luciferase report experiment confirmed that COX2 was the target gene of miR-211-5p. The relative expression of Notch1, Jagged1, and Hes1 mRNA in peripheral blood of patients with severe myelosuppression were 2.35±0.41, 2.76±0.46 and 3.04±0.52, respectively, which were significantly lower than those in patients with mild myelosuppression (4.12±0.63, 4.53±0.58 and 5.12±0.67) ( t=5.367, 6.114 and 6.135, respectively, P<0.001) . After transfecting SD rat bone marrow mesenchymal stem cells with miR-211-5p mimics and inhibitors, the relative expression of miR-211-5p in the mimic group was 3.46±0.49, significantly higher than that in the mimic NC group (2.24±0.32) The relative expression of miR-211-5p in the inhibitor group was (1.28±0.19) and (2.33±0.37) inhibitor NC group ( P<0.001) , while the relative expression of miR-211-5p in the inhibitor group was significantly lower than that in the other three groups ( P<0.001) . The mRNA expression of COX2 gene in mimic group was 2.73±0.36, which was significantly lower than that in mimic NC group (4.05±0.59) , inhibitor group (6.15±0.86) and inhibitor NC group (4.18±0.65) ( P<0.001) , while mRNA expression of COX2 gene in the inhibitor group was significantly higher than that in the other three groups ( P<0.001) . The expression of Notch1, Jagged1, and Hes1 in the inhibitor group was significantly increased, while the expression of Notch1, Jagged1, and Hes1 in the mimic group was significantly decreased. Conclusion:The expression level of miR-211-5p in peripheral blood of severe myelosuppressed patients with breast cancer after neoadjuvant chemotherapy is significantly increased, and the Notch signaling pathway can be inhibited by targeted down-regulation of COX2 gene expression.

ABSTRACT

Objective:To observe the efficacy and safety of anlotinib combined with chemotherapy in patients with advanced non-small cell lung cancer (NSCLC) who failed second-line chemotherapy.Methods:A retrospective analysis was performed on 80 patients with advanced NSCLC who had failed second-line chemotherapy admitted in the Department of Oncology of Chaohu Hospital of Anhui Medical University from January 2017 to October 2019, and the patients were divided into control group ( n=36) and observation group ( n=44) according to the different treatment regimens. The control group was given pemetrexed + cisplatin, and the observation group adopted pemetrexed + cisplatin + anlotinib. The objective response rate (ORR), disease control rate (DCR), median progression-free survival (PFS), overall survival (OS), changes in levels of serum vascular endothelial growth factor (VEGF), carcinoembryonic antigen (CEA) and carbohydrate antigen 199 (CA199) and treatment-related adverse reactions were compared between the two groups. Results:After 2 cycles of treatment, the ORR in the control group and observation group were 5.56% (2/36) and 18.18% (8/44), with no statistically significant difference ( χ2=1.85, P=0.174). The DCR in the two groups were 58.33% (21/36) and 81.82% (36/44), and the DCR in the observation group was significantly higher than that in the control group, with a statistically significant difference ( χ2=5.33, P=0.021). The median PFS in the two groups were 4.0 months and 6.0 months, and the median PFS in the observation group was longer than that in the control group, with a statistically significant difference ( χ2=28.47, P<0.001). The median OS in the two groups were 13.0 months and 14.8 months, with no statistically significant difference ( χ2=1.56, P=0.212). The levels of serum VEGF [(21.72±5.42) ng/L vs. (36.97±7.53) ng/L, t=14.13, P<0.001; (16.61±4.14) ng/L vs. (38.85±8.61) ng/L, t=23.09, P<0.001], CEA [(4.91±1.58) ng/ml vs. (6.62±2.84) ng/ml, t=4.64, P<0.001; (3.07±1.32) ng/ml vs. (7.08±3.31) ng/ml, t=11.50, P<0.001] and CA199 [(16.83±5.23) U/ml vs. (20.95±7.94) U/ml, t=3.75, P<0.001; (13.37±5.85) U/ml vs. (21.66±8.72) U/ml, t=7.55, P<0.001] in the control group and observation group after 2 cycles of treatment were significantly decreased compared with those before treatment, and the levels of serum VEGF, CEA and CA199 in the observation group were significantly lower than those in the control group ( t=4.78, P<0.001; t=5.68, P<0.001; t=2.76, P=0.007). The incidence of elevated blood pressure in the observation group was significantly higher than that in the control group [25.00% (11/44) vs. 2.78% (1/36), χ2=7.67, P=0.006]. Conclusion:Pemetrexed + cisplatin + anlotinib regimen for patients with advanced NSCLC who failed second-line chemotherapy can improve DCR, prolong PFS and improve the levels of serum tumor-related markers, with controllable adverse reactions.
