ABSTRACT

Objective: To evaluate the influence of duodenal stump reinforcing on the short-term complications after laparoscopic radical gastrectomy. Methods: A retrospective cohort study with propensity score matching (PSM) was conducted. Clinical data of 1204 patients with gastric cancer who underwent laparoscopic radical gastrectomy at the First Affiliated Hospital of Army Medical University from April 2009 to December 2018 were collected. The digestive tract reconstruction methods included Billroth II anastomosis, Roux-en-Y anastomosis and un-cut-Roux- en-Y anastomosis. A linear stapler was used to transected the stomach and the duodenum. Among 1204 patients, 838 were males and 366 were females with mean age of (57.0±16.0) years. Duodenal stump was reinforced in 792 cases (reinforcement group) and unreinforced in 412 cases (non-reinforcement group). There were significant differences in resection range and anastomotic methods between the two groups (both P<0.001). The two groups were matched by propensity score according to the ratio of 1∶1, and the reinforcement group was further divided into purse string group and non-purse string group. The primary outcome was short-term postoperative complications (within one month after operation). Complications with Clavien-Dindo grade ≥ III a were defined as severe complications, and the morbidity of complication between the reinforcement group and the non-reinforcement group, as well as between the purse string group and the non-purse string group was compared. Results: After PSM, 411 pairs were included in the reinforcement group and the non-reinforcement group, and there were no significant differences in baseline data between the two groups (all P>0.05). No perioperative death occurred in any patient.The short-term morbidity of postoperative complication was 7.4% (61/822), including 14 cases of anastomotic leakage (23.0%), 11 cases of abdominal hemorrhage (18.0%), 8 cases of duodenal stump leakage (13.1%), 2 cases of incision dehiscence (3.3%), 6 cases of incision infection (9.8%) and 20 cases of abdominal infection (32.8%). Short-term postoperative complications were found in 25 patients (6.1%) and 36 patients (8.8%) in the reinforcement group and the non-reinforcement group, respectively, without significant difference (χ2=2.142, P=0.143). Nineteen patients (2.3%) developed short-term severe complications (Clavien-Dindo grade ≥IIIa), while no significant difference in severe complications was found between the two groups (1.7% vs. 2.9%, χ2=1.347, P=0.246). Sub-group analysis showed that the morbidity of short-term postoperative complication of the purse string group was 2.6% (9/345), which was lower than 24.2% (16/66) of the non-purse string group (χ2=45.388, P<0.001). Conclusion: Conventional reinforcement of duodenal stump does not significantly reduce the incidence of duodenal stump leakage, so it is necessary to choose whether to reinforce the duodenal stump individually, and purse string suture should be the first choice when decided to reinforce.

ABSTRACT

This study aimed to assess the association between psychological disorders and erectile dysfunction (ED) in patients with different degrees of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). This was a retrospective study conducted from June 2017 to October 2019 and included 182 outpatients. Patients were interviewed using the Structured Interview on Erectile Dysfunction (SIEDY) for pathogenic quantification. The National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI) and the International Index of Erectile Function-5 (IIEF-5) were used for the evaluation of CP/CPPS and ED. The Generalized Anxiety Disorder-7 (GAD-7) and Patient Health Questionnaire-9 (PHQ-9) were used to assess anxiety symptoms and depressive symptoms. The number of patients with mild CP/CPPS and mild ED, mild CP/CPPS and moderate-to-severe ED, moderate-to-severe CP/CPPS and mild ED, and moderate-to-severe CP/CPPS and moderate-to-severe ED was 69 (37.9%), 36 (19.8%), 35 (19.2%), and 42 (23.1%), respectively. The corresponding PHQ-9 scores of the four groups were 6.22, 7.19, 10.69, and 7.71, respectively. The corresponding GAD-7 scores of the four groups were 5.26, 6.31, 8.77, and 6.36, respectively. Among patients with moderate-to-severe CP/CPPS, the PHQ-9 and GAD-7 scores of the moderate-to-severe ED group were significantly lower than those of the mild ED group (P = 0.007 and P = 0.010, respectively). The prevalence of ED and premature ejaculation (PE) in patients with moderate-to-severe CP/CPPS was significantly higher than that in patients with mild CP/CPPS (P = 0.001 and P = 0.024, respectively). Our findings proved that the severity of ED was negatively associated with psychological symptoms in outpatients with moderate-to-severe CP/CPPS.

ABSTRACT

Purpose@#The present study assessed the role of an amino acid-based formula (AAF) in the growth of infants with cow's milk protein allergy (CMPA). @*Methods@#Non-breastfed, term infants aged 0–6 months with symptoms suggestive of CMPA were recruited from 10 pediatric centers in China. After enrollment, infants were started on AAF for two weeks, followed by an open food challenge (OFC) with cow's milk-based formula (CMF). Infants with confirmed CMPA remained on AAF until 9 months of age, in conjunction with a cow's milk protein-free complementary diet. Body weight, length, and head circumference were measured at enrollment and 9 months of age. Measurements were converted to weight-for-age, length-for-age, and head circumference-for-age Z scores (WAZ, LAZ, HCAZ), based on the World Health Organization growth reference. @*Results@#Of 254 infants (median age 16.1 weeks, 50.9% male), 218 (85.8%) were diagnosed with non-IgE-mediated CMPA, 33 (13.0%) tolerated CMF, and 3 (1.2%) did not complete the OFC. The mean WAZ decreased from 0.119 to −0.029 between birth and enrollment (p=0.067), with significant catch-up growth to 0.178 at 9 months of age (p=0.012) while being fed the AAF. There were no significant changes in LAZ (0.400 vs. 0.552; p=0.214) or HCAZ (−0.356 vs. −0.284; p=0.705) from the time of enrollment to age 9 months, suggesting normal linear and head growth velocity. @*Conclusion@#The amino acid-based study formula, in conjunction with a cow's milk proteinfree complementary diet, supported normal growth till 9 months of age in a cohort of Chinese infants with challenge-confirmed non-IgE-mediated CMPA.

ABSTRACT

The pathogenesis of very-long-chain acyl-CoA dehydrogenase (VLCAD) deficiency is highly heterogeneous and still unclear. Additional novel variants have been recently detected in the population. The molecular and cellular effects of these previously unreported variants are still poorly understood and require further characterization. To address this problem, we have evaluated the various functions and biochemical consequences of six novel missense variants that lead to mild VLCAD deficiency. Marked deficiencies in fatty acid oxidation (FAO) and other mitochondrial defects were observed in cells carrying one of these six variants (c.541C>T, c.863T>G, c.895A>G, c.1238T>C, c.1276G>A, and c.1505T>A), including reductions in mitochondrial respiratory-chain function and adenosine triphosphate (ATP) production, and increased levels of mitochondrial reactive oxygen species (ROS). Intriguingly, higher apoptosis levels were found in cells carrying the mutant VLCAD under glucose-limited stress. Moreover, the stability of the mutant homodimer was disturbed, and major conformational changes in each mutant VLCAD structure were predicted by molecular dynamics (MD) simulation. The data presented here may provide valuable information for improving management of diagnosis and treatment of VLCAD deficiency and for a better understanding of the general molecular bases of disease variability.

ABSTRACT

Objective:To explore the curative effect and mechanism of Tongnao pill in the treatment of senile posterior circulation ischemic vertigo with phlegm and blood stasis type. Method:The 80 elderly patients with posterior circulation ischemic vertigo (phlegm and blood stasis type) admitted to Gansu Provincial Hospital of Traditional Chinese Medicine were selected as the research subjects and were randomly divided into two groups according to the hospital admission number. Those with odd numbers were classified into control group and those with even numbers were classified into observation group, with 40 cases in each group. All of the patients in both groups were given basic treatment, and the patients in control group additionally received intravenous infusion of vinpocetine on the basis of basic treatment, while the patients in observation group additionally received Tongnao pill on the basis of the treatment in control group. The clinical efficacy, traditional Chinese medicine (TCM) syndrome score, European Evaluation of Vertigo(EEV) score, dizziness handicap inventory-screening (DHI-S) score, vertebral basilar artery average blood flow velocity(Vm) and pulsatility index(PI), hemodynamic changes[mean arterial pressure(MAP), central venous pressure(CVP), right atrial pressure (RAP), left atrial pressure(LAP), cardiac output(CO), cardiac stroke volume(SV)], changes in blood viscosity and blood lipid levels,symptom disappearance time, and safety of the two groups were compared. Result:The total effective rate in the observation group was 95.00% (38/40), significantly higher than 75.00% (30/40) in the control group (χ2=4.804, P<0.05). After treatment, the symptoms were significantly improved in both groups (P<0.05), and the scores of dizziness, nausea and vomiting, tinnitus and deafness, tiredness and fatigue in the observation group were lower than those in the control group (P<0.05), the EEV and DHI-S scores were decreased significantly in both groups(P<0.05), and such scores in the observation group were significantly lower than those in the control group(P<0.05), the Vm of bilateral vertebral artery (VA) and basilar artery (BA) on both sides were significantly increased in both groups, while the PI was significantly reduced (P<0.05), and these two indicators in the observation group were better than those in the control group (P<0.05), the MAP, CVP, RAP and LAP were significantly reduced in both groups after treatment, while the CO and SV were increased after treatment(P<0.05), and the SV of the observation group was significantly higher than that of the control group(P<0.05). The high blood viscosity, low blood viscosity, plasma viscosity and TG, TC, LDL-C levels were decreased significantly while HDL-C increased significantly in both groups (P<0.05), and the blood viscosity and blood lipid levels in the observation group were significantly better than those in the control group(P<0.05). The time to disappearance of dizziness, nausea, vomiting, tinnitus and deafness, malaise, fatigue, and confused mind in observation group was less than that in the control group (P<0.05), no serious adverse events occurred in both groups. Conclusion:Tongnao pills for the treatment of senile posterior circulation ischemic vertigo (phlegm and blood stasis type) can significantly alleviate the symptoms of vertigo, improve hemorrheology, increase the blood flow velocity of the vertebrobasilar artery, improve the abnormal blood supply to the brain, and improve the quality of life for patients, with fewer adverse reactions, high safety, and good therapeutic effect. Therefore, it is worth to be applied in clinical use.

ABSTRACT

@#Objective: To explore the gene transduction method of chimeric antigen receptor (CAR) mediated by novel cationic polymer nanocarrier mPEG-P (Asp-AED-g-HFB) (PAEF) and PigyBac transposon system to modify natural killer (NK) cells, providing a new strategy for immunotherapy of cancer cells. Methods: PAEF/DNA (transposase+transposon) complex were prepared. The particle size distribution and surface potential of PAEF/DNA complexes were measured with Nano-ZSE Dynamic Light Scattering System (Malvern Instruments). The DNA encapsulation rate, release and stability of PAEF were evaluated by DNA gel electrophoresis, and then by combiningwithparticlesizeandsurfacepotentialtodeterminethepreferentialN/PratiotoenterNKcells.Thecell cytotoxicity of PAEF/DNA complexes under different N/P ratios was analyzed by CCK-8 cytotoxicity test. Transduction efficiency of NK cells was evaluated by Fluorescence microscopy and Flow cytometry, and the feasibility of PAEF gene transfection vectors was assessed. Results: PAEF could encapsulate DNA to form nano-complexes with the diameter of 100-150 nm, which was suitable to mediate DNA entering into cells. PAEF could completely encapsulate DNA with N/P ratio of 20. In the presence of reducing agent dithiothreitol (DTT), PAEF had a good ability to release DNA. NK-92 cells transfected with PAEF/DNA complex, which was formed at the N/P ratio of 80, attained a significantly higher cell viability than cells of lipofectamine transfection group [(72.50±3.9)% vs (64.03±1.8)%, P<0.05]; Fluorescence microscopic observation showed more fluorescence and higher fluorescence intensity in cells of PAEF/DNA group; Flow cytometry showed the highest transfection efficiency of 83.4%. Conclusions: Nanocarrier PAEF can encapsulate DNA well by electrostatic adsorption, and has good biocompatibility and high efficiency for gene transduction. It provides a good experimental basis for adoptive immunotherapy.

ABSTRACT

OBJECTIVE@#This study aimed to determine the prevalence and related factors of deciduous caries in 3-5-year-old preschool children in Chongqing city. Results will be used to provide a basis for the establishment and adjustment of prevention and intervention of caries in preschool children.@*METHODS@#We referred to the Fourth National Oral Health Epidemiological Survey. Data included caries prevalence in preschool children, and the questionnaires were distributed to children' parents in Chongqing city. Results were inputted by Epidata 3.1 and statistically analyzed using SPSS 21.0.@*RESULTS@#A total of 1 350 preschool children were included in the study. We found that maxillary deciduous central incisor and mandibular deciduous molars were susceptible to decay. The prevalence of primary teeth caries in preschool children in Chongqing city was 51.4% (694/1 350). The mean decayed-missing-filled-teeth (dmft) index was 2.34. The caries prevalence and mean dmft between age groups were statistically significant (P0.05). Approximately 61.7% of caries cases were concentrated in a small number (36.1%) of individuals. Multivariate Logistic regression analysis showed that age, highest educational level of parents, intake frequency of sweetened beverages and carbonated drinks, toothache or similar discomfort experience over the past year, dentist visits, and parents' assessment of teeth and oral health status of children were the factors influencing the prevalence of deciduous caries (P<0.05).@*CONCLUSIONS@#More than half of the preschool children had dental caries. Majority of caries were concentrated in a small number of individuals. The age of children, highest educational level of parents, intake frequency of sweetened beverages and carbonated drinks, toothache or discomfort experience over the past year, dentist visits, and parents' assessment of teeth and oral health status of children were associated with the prevalence of deciduous caries.

ABSTRACT

Objective@#To observe the effects of abnormal body temperature and the area under temperature curve on the prognosis of patients with septic shock.@*Methods@#A retrospective cohort study was conducted. Patients with septic shock admitted to intensive care unit (ICU) of Wuxi People's Hospital Affiliated to Nanjing Medical University from September 2013 to June 2019 were enrolled. Data were obtained from the hospital case database, including the gender, age, infection source, the length of ICU stay, sequential organ failure assessment (SOFA) score, 21-day prognosis; within the first 24 hours and throughout the period in ICU, the maximum temperature (24 h Tmax, Tmax), lowest temperature (24 h Tmin, Tmin), and the temperature range (24 h Tmax-min, Tmax-min) were aggregated. The area under temperature curve when body temperature was higher than T (A > T), or lower than T (A < T), and area section between T1 and T2 (AT1-T2) was calculated respectively. Patients were divided into survival group and death group according to 21-day prognosis. Binary Logistic regression was used to analyze the effect of the above temperature indices on the prognosis.@*Results@#635 septic shock patients were enrolled in the study. 476 patients were survived and 159 died within 21 days. Compared with the survival group, the age, SOFA score were higher in the death group, while the length of ICU stay was shorter. There was no significant difference in gender or infection source between two groups. After adjusting for gender, age, the length of ICU stay and SOFA score, binary Logistic regression analysis showed that the increase of Tmax, decrease of Tmin, and increase of Tmax-min were risk factors for 21-day mortality [Tmax: odds ratio (OR) = 2.959, 95% confidence interval (95%CI) was 1.620-5.398, P < 0.001; Tmin: OR = 0.329, 95%CI was 0.140-0.790, P = 0.012; Tmax-min: OR = 3.258, 95%CI was 1.840-5.471, P < 0.001], while 24 h Tmax, 24 h Tmin and 24 h Tmax-min were not related to prognosis. A < 36.0 ℃ (OR = 1.335, 95%CI was 1.102-1.745, P = 0.014), and A > 38.0 ℃ (OR = 1.041, 95%CI was 1.019-1.077, P = 0.001) showed positive correlation with 21-day mortality. When the T level was set at 38.0-40.0 ℃, for every 1 ℃×hour increase in A > T, the 21-day relative risk of death increased by 4.1%-83.2%.@*Conclusion@#When the body temperature of patients with septic shock is lower than 36.0 ℃, or higher than 38.0 ℃, the 21-day relative risk of death rose with the increase of the magnitude and duration of abnormal body temperature.

After adjusting for gender, age, the length of ICU stay and SOFA score, binary Logistic regression analysis showed that the increase of Tmax, decrease of Tmin, and increase of Tmax-min were risk factors for 21-day mortality [Tmax: odds ratio (OR) = 2.959, 95% confidence interval (95%CI) was 1.620-5.398, P < 0.001; Tmin: OR = 0.329, 95%CI was 0.140-0.790, P = 0.012; Tmax-min: OR = 3.258, 95%CI was 1.840-5.471, P < 0.001], while 24 h Tmax, 24 h Tmin and 24 h Tmax-min were not related to prognosis. A < 36.0 ℃ (OR = 1.335, 95%CI was 1.102-1.745, P = 0.014), and A > 38.0 ℃ (OR = 1.041, 95%CI was 1.019-1.077, P = 0.001) showed positive correlation with 21-day mortality. When the T level was set at 38.0-40.0 ℃, for every 1 ℃×hour increase in A > T, the 21-day relative risk of death increased by 4.1%-83.2%. Conclusion When the body temperature of patients with septic shock is lower than 36.0 ℃, or higher than 38.0 ℃, the 21-day relative risk of death rose with the increase of the magnitude and duration of abnormal body temperature.

ABSTRACT

Objective To observe the effects of abnormal body temperature and the area under temperature curve on the prognosis of patients with septic shock. Methods A retrospective cohort study was conducted. Patients with septic shock admitted to intensive care unit (ICU) of Wuxi People's Hospital Affiliated to Nanjing Medical University from September 2013 to June 2019 were enrolled. Data were obtained from the hospital case database, including the gender, age, infection source, the length of ICU stay, sequential organ failure assessment (SOFA) score, 21-day prognosis; within the first 24 hours and throughout the period in ICU, the maximum temperature (24 h Tmax, Tmax), lowest temperature (24 h Tmin, Tmin), and the temperature range (24 h Tmax-min, Tmax-min) were aggregated. The area under temperature curve when body temperature was higher than T (A > T), or lower than T (A < T), and area section between T1 and T2 (AT1-T2) was calculated respectively. Patients were divided into survival group and death group according to 21-day prognosis. Binary Logistic regression was used to analyze the effect of the above temperature indices on the prognosis. Results 635 septic shock patients were enrolled in the study. 476 patients were survived and 159 died within 21 days. Compared with the survival group, the age, SOFA score were higher in the death group, while the length of ICU stay was shorter. There was no significant difference in gender or infection source between two groups. After adjusting for gender, age, the length of ICU stay and SOFA score, binary Logistic regression analysis showed that the increase of Tmax, decrease of Tmin, and increase of Tmax-min were risk factors for 21-day mortality [Tmax: odds ratio (OR) = 2.959, 95% confidence interval (95%CI) was 1.620-5.398, P < 0.001; Tmin: OR = 0.329, 95%CI was 0.140-0.790, P = 0.012; Tmax-min: OR = 3.258, 95%CI was 1.840-5.471, P < 0.001], while 24 h Tmax, 24 h Tmin and 24 h Tmax-min were not related to prognosis. A < 36.0 ℃ (OR = 1.335, 95%CI was 1.102-1.745, P = 0.014), and A > 38.0 ℃ (OR = 1.041, 95%CI was 1.019-1.077, P = 0.001) showed positive correlation with 21-day mortality. When the T level was set at 38.0-40.0 ℃, for every 1 ℃×hour increase in A > T, the 21-day relative risk of death increased by 4.1%-83.2%.

ABSTRACT

The research aims to study the effects of different stimulants on the activation of human lymphocytes. Human peripheral blood mononuclear cells were prepared by density centrifugation. The blood's sample was provided by National Institutes for Food and Drug Control and approved by its Ethics Committee. The expressions of CD69 in CD3+CD4+ and CD3+CD8+ human T cells were detected by flow cytometry after administrated with CD3/CD28 antibody, phytohaemagglutinin (PHA), Staphylococcus auresus enterooxin B (SEB), interleukin (IL27) and PMA plus ionomycin for 24 h. The proliferation of lymphocyte was detected by CellTiter-Glo kit. The secreted IFNγ in supernatant of medium was examined by ELISA kit. The proliferation of lymphocytes had no change after exposed of CD3/CD28 antibody, SEB, IL27 and PMA plus ionomycin for 24 h. However, the CD69 expressions in CD3+CD4+ and CD3+CD8+ T cells and IFNγ productions were significantly increased by CD3/CD28 antibody, SEB, IL27 and PMA plus ionomycin at 24 h, indicating that CD3+CD4+ and CD3+CD8+ T cells were activated under above-mentioned stimulated condition. CD3/CD28 antibody, SEB, IL27 and PMA plus ionomycin were valid stimulants for T cell activation.

ABSTRACT

OBJECTIVE@#To investigate the epidemiological characteristics, phenotype, genotype, and prognosis of medium-chain acyl-CoA dehydrogenase deficiency (MCADD) in the Chinese population.@*METHODS@#A retrospective analysis was performed for the clinical data of the neonates who underwent screening with high-performance liquid chromatography-tandem mass spectrometry from January 2009 to June 2018 and were diagnosed with MCADD by gene detection.@*RESULTS@#A total of 2 674 835 neonates underwent neonatal screening, among whom 12 were diagnosed with MCADD. Gene detection was performed for 10 neonates with MCADD and found 13 mutation types at 16 mutation sites of the ACADM gene, among which there were 7 reported mutations (p.T150Rfs*4, p.M1V, p.R206C, p.R294T, p.G310R, p.M328V, and p.G362E), 5 novel mutations (p.N194D, p.A324P, p.N366S, c.118+3A>G, and c.387+1del G), and 1 exon 11 deletion; p.T150Rfs*4 was the most common mutation (4/16). The detection rate of mutation sites in the ACADM gene was 80%. No phenotype-genotype correlation was observed. Dietary guidance and symptomatic treatment were given after confirmed diagnosis. No acute metabolic imbalance was observed within 4-82 months of follow-up. All neonates had good prognosis except one who had brain dysplasia.@*CONCLUSIONS@#MCADD is relatively rare in southern China, and p.T150Rfs*4 is a common mutation in the Chinese population. Cases with positive screening results should be evaluated by octanoylcarnitine C8 value and gene detection.

ABSTRACT

Standardized residency training is the only way for medical students to grow into qualified doctors. Since the implementation of pediatric standardized residency training nationwide in 2014,the training has been progressing smoothly and has made remarkable achievements. In order to further adapt to the status of residential training,meet the needs of pediatric training nationwide and improve the quality of pediatric training,the Pediatric Professional Committee organized experts to brainstorm and revise the two criteria, "Pediatric Criteria for Standardized Residency Training Base" and "Pediatric Criteria for Standardized Residency Training Contents". The revision of these two criteria follows the principles of continuity,accessibility,advancement and consistency. Revision was focused on lowering the scale of the base,proposing the concept of professional group,making rotation of specialty flexible,and strengthening stratified training. We hope to improve the capability of base to improve the comprehensive ability of residential students without increasing the bed size. It is believed that the pediatric standardized residency training system will provide a solid foundation for the pediatric training through providing good policy guidance,support,and medical and educational cooperation.
