ABSTRACT

OBJECTIVES@#To study the survival rate and the incidence of complications of very preterm infants and the factors influencing the survival rate and the incidence of complications.@*METHODS@#The medical data of the very preterm infants with a gestational age of <32 weeks and who were admitted to the Department of Neonatology in 11 hospitals of Jiangsu Province in China from January 2018 to December 2019 were retrospectively reviewed. Their survival rate and the incidence of serious complications were analyzed. A multivariate logistic regression analysis was used to evaluate the risk factors for death and serious complications in very preterm infants.@*RESULTS@#A total of 2 339 very preterm infants were enrolled, among whom 2 010 (85.93%) survived and 1 507 (64.43%) survived without serious complications. The groups with a gestational age of 22-25@*CONCLUSIONS@#The survival rate is closely associated with gestational age in very preterm infants. A low 1-minute Apgar score (≤3) may increase the risk of death in very preterm infants, while high gestational age, high birth weight, and prenatal use of glucocorticoids are associated with the reduced risk of death. A low 5-minute Apgar score (≤3) and maternal chorioamnionitis may increase the risk of serious complications in these infants, while high gestational age and high birth weight may reduce the risk of serious complications.

ABSTRACT

BK polyomavirus-associated nephropathy (BKPyVAN) is a common cause of allograft failure. However, differentiation between BKPyVAN and type I T cell-mediated rejection (TCMR) is challenging when simian virus 40 (SV40) staining is negative, because of the similarities in histopathology. This study investigated whether donor-derived cell-free DNA (ddcfDNA) can be used to differentiate BKPyVAN. Target region capture sequencing was applied to detect the ddcfDNAs of 12 recipients with stable graft function, 22 with type I TCMR, 21 with proven BKPyVAN, and 5 with possible PyVAN. We found that urinary ddcfDNA levels were upregulated in recipients with graft injury, whereas plasma ddcfDNA levels were comparable for all groups. The median urinary concentrations and fractions of ddcfDNA in proven BKPyVAN recipients were significantly higher than those in type I TCMR recipients (10.4 vs. 6.1 ng/mL,

ABSTRACT

Circadian clock is an internal autonomous time-keeping system, including central clocks located in the suprachiasmatic nucleus (SCN) and peripheral clocks. The molecular circadian clock consists of a set of interlocking transcriptional-translational feedback loops that take the clock-controlled genes 24 h to oscillate. The core mechanism of molecular circadian clock is that CLOCK/BMAL1 dimer activates the transcription of cryptochromes (CRYs) and Periods (PERs), which act as transcriptional repressors of further CLOCK/BMAL1-mediated transcription. In addition to this basic clock, there is an additional sub-loop of REV-ERBα and RORα regulating the transcription of BMAL1. Approximately 80% protein-coding genes demonstrate significant rhythmicity. The earth rotation is responsible for the generation of the daily circadian rhythms. To coordinate metabolic balance and energy availability, almost all organisms adapt to the rhythm. Studies have shown that circadian clock integrating with metabolic homeostasis increases the efficiency of energy usage and coordinates with different organs in order to adapt to internal physiology and external environment soon. As the central organ of metabolism, the liver performs various physiological activities nearly all controlled by the circadian clock. There are multiple interactive regulation mechanisms between the circadian clock and the regulation of liver metabolism. The misalignment of metabolism with tissue circadian is identified as a high-risk factor of metabolic diseases. This article reviews the recent studies on circadian physiological regulation of liver glucose, lipid and protein metabolism and emphasizes oscillation of mitochondrial function. We also take an outlook for new methods and application of circadian clock research in the future.

ABSTRACT

In order to reveal the distribution and population characteristics of endophytic fungi from Zanthoxylum nitidum and the antibacterial potential,this study performed molecular identification and analyzed the genetic diversity and antibacterial activity of endophytic fungi from Z. nitidum in Guangxi. Through culture and molecular identification,35 strains,belonging to 15 genera,12 families,10 orders,4 classes,and 2 phyla,were isolated from various tissues of Z. nitidum,of which Colletotrichum and Fusarium were the dominant genera,respectively accounting for 20% of total strains. The diversity of endophytic fungi was significantly different among roots,stems,and leaves,as manifested by the significantly higher Shannon index( H') in stems( 1. 678) than in roots( 0. 882 1) and leaves( 0. 515 4). The antimicrobial activity analysis showed that 14. 28% of endophytic fungi inhibited at least one indicator pathogen. Among them,Fusarium sp. ZN-34 and Fusarium sp. ZN-26 separately demonstrated the strongest inhibitory effect on Escherichia coli and Staphylococcus aureus. In general,Fusarium sp. ZN-26 and Phialemoniopsis plurioloculosa ZN-35 were advantageous in suppressing the two bacteria owing to the broad spectrum and strong efficacy. In summary,Z. nitidum in Guangxi boasts rich endophytic fungi with the majority showing strong antibacterial activity,which can be used as candidates for the extraction and separation of basic antibacterial substances and the development of natural antibacterial agents.

ABSTRACT

Objective:To investigate the value of bedside transthoracic echocardiography(TTE) in volume reactivity assessment of children with septic shock.Methods:A total of 41 children aged from 1 to 5 years with septic shock requiring mechanical ventilation admitted to PICU from January 2017 to June 2020 were prospectively included.Under the condition of complete mechanical ventilation, full sedation and analgesia, and no spontaneous breathing(tidal volume 8 to 10 mL/kg), volume expansion was given to children.Hemodynamic indexs such as cardiac index(CI), stroke volume index(SVI) and stroke volume variability(SVV) were measured before and after volume expansion by noninvasive cardiac output monitoring(NICOM) and TTE.Moreover, aortic flow velocity time integral variable degrees(ΔVTI), inferior vena cava variability(ΔIVC) and inferior vena cava dilation index(dIVC) were also measured by TTE.Patients were considered to be responsive to volume expansion if SVI NICOMincreased≥15%.Based on the responsiveness of volume expansion, all the patients were divided into response group and non-response group.The value of SVV TTE, ΔVTI, ΔIVC, dIVC, ΔCVP and SVV NICOMin predicting volume responsiveness were analysed. Results:(1) There were 23 cases in response group and 18 cases in non-response group.Before volume expansion, there were no statistically significant differences in general hemodynamic indexes HR, MAP, CVP, EF, CI NICOM, and CI TTEbetween two groups( P>0.05). (2) In response group, HR, MAP, CI, SVI and CVP were all improved after volume expansion( P<0.001). In non-response group, only CVP was significantly increased after volume expansion, while other indexes were not improved( P>0.05). (3)Before the volume expansion, SVV TTE, ΔVTI, ΔIVC, and dIVC in response group were higher than those in non-response group( P<0.001). After volume expansion, these indicators were significantly reduced in response group.In non-response group, only ΔIVC significantly reduced after volume expansion.(4) The receiver-operating characteristic curve analysis showed that the area under the curve of SVV TTEand ΔVTI was 0.971, with 12.04% as the threshold, the sensitivity was 0.957 and the specificity was 0.944. The area under the curve of ΔIVC was 0.981, with 25.98% as the threshold, the sensitivity was 0.870 and the specificity was 1.000.The area under the curve of dIVC was 0.980, with 29.86% as the threshold, the sensitivity was 0.870 and the specificity was 1.000. The area under the curve of ΔCVP was 0.778, with 2.5 cmH 2O(1 cmH 2O=0.098 kPa) as the threshold, the sensitivity was 0.913 and the specificity was 0.556. The area under the curve of SVV NICOMwas 0.874, with 12.50% as the threshold, the sensitivity was 0.869 and the specificity was 0.778. Conclusion:The dynamic indexes SVV, ΔVTI, ΔIVC and dIVC monitored by TTE have good accuracy in evaluating children′s volume responsiveness, among which the accuracy of ΔIVC and dIVC is relatively the highest; the value of ΔCVP in predicting volume responsiveness is limited.

ABSTRACT

Objective:To investigate the incidence of asthma and the characteristics of acute attacks in children aged 3-14 in different administrative areas of Wuxi, and to analyze the correlation of asthma with the outdoor environmental factors.Methods:A total of 10 175 children aged 3-14 were randomly selected from 5 different administrative regions in Wuxi City, Jiangsu Province for childhood asthma epidemiological survey from January to December in 2017.Results:The complete questionnaires were collected from 8 318 children with a response rate of 81.70%.There were 6 734 valid questionnaires.Asthma occurred to 259 children, and the prevalence rate was 3.84%.The prevalence of asthma in male and female children was 4.89% (163 cases) and 2.82% (96 cases), respectively.The ratio of male patients to female patients was 1.70∶1.00, and the difference was significant ( χ2=19.72, P<0.01). Children were most prone to suffer from asthma attacks at the turn of seasons (87/259 cases, 33.59%). The frequency of asthma was the lowest from June to August (9/259 cases, 3.47%). Among 244 cases attacked by acute asthma, the prevailing time period of acute attacks was irregular in 88 patients (36.07%), bedtime in 64 cases (26.23%). In different regions of the city, the lowest prevalence rate of asthma was found in Binhu District (50/1 830 cases, 2.73%), the highest prevalence rate of asthma was found in Xinwu District (71/1 502 cases, 4.72%), the difference between the highest and lowest prevalence rates of asthma was significant ( χ2=13.19, P<0.05). In terms of the air quality in different admi-nistrative regions of Wuxi, the nitrogen dioxide (NO 2) concentration, the carbon monoxide (CO) concentration, PM 10 and PM 2.5 in Binhu District were lower than other 4 regions.In different seasons in Wuxi city, the sulfur dioxide(SO 2) concentration, the NO 2 concentration, the CO concentration, PM 10 and PM 2.5 from June to August were significantly lower than those in other months.The prevalence of asthma in children in different administrative districts of Wuxi was weakly positively correlated with the SO 2 concentration, the NO 2 concentration and PM 10 ( r=0.10, P<0.01; r=0.22, P<0.01; r=0.06, P<0.01, respectively). The prevalence of asthma was weakly negatively associated with the ozone(O 3) concentration ( r=-0.06, P<0.01). Acute asthma attacks were weakly positively correlated with the SO 2 concentration ( r=0.22, P<0.01), the NO 2 concentration ( r=0.28, P<0.01), the CO concentration ( r=0.23, P<0.01), PM 10 ( r=0.18, P<0.01) and PM 2.5 ( r=0.18, P<0.01), and weakly negatively correlated with the O 3 concentration ( r=-0.40, P<0.01). Conclusions:The prevalence of asthma in Wuxi is higher in boys than in girls, and the frequency of asthma attacks is related to the season.The SO 2, NO 2, CO, PM 10, PM 2.5 and O 3 concentration affect the prevalence and acute attacks of asthma.

ABSTRACT

Purpose@#This study aimed to elucidate whether lncRNA ZFAS1 is involved in neuronal apoptosis and inflammation in temporal lobe epilepsy (TLE). @*Materials and Methods@#Ninety-six TLE patients were recruited, and their peripheral venous blood was gathered to determine Zfas1 expression with polymerase chain reaction. Neurons were separated from hippocampal tissue of newborn SD rats, and siZfas1 or pcDNA3.1-Zfas1 was transfected into the neurons. Inflammatory cytokines released by neurons were determined, and neuronal activities were evaluated through MTT assay, colony formation assay, and flow cytometry. @*Results@#Serum levels of Zfas1 were higher in TLE patients than in healthy controls (p<0.05). Furthermore, Zfas1 expression in neurons was raised by pcDNA3.1-Zfas1 and declined after silencing of Zfas1 (p<0.05). Transfection of pcDNA-Zfas1 weakened the viability and proliferation of neurons and increased neuronal apoptosis (p<0.05). Meanwhile, pcDNA3.1-Zfas1 transfection promoted lipopolysaccharide-induced release of cytokines, including tumor necrosis factor-α, interleukin (IL)-1, IL-6, and intercellular adhesion molecule-1 (p<0.05), and boosted NF-κB activation by elevating the expression of NF-κB p65, pIκBα, and IKKβ in neurons (p<0.05). @*Conclusion@#Our results indicated that lncRNA ZFAS1 exacerbates epilepsy development by promoting neuronal apoptosis and inflammation, implying ZFAS1 as a promising treatment target for epilepsy.

ABSTRACT

Objective@#To evaluate the efficacy and safety of 0.05% atropine eye drops for retarding myopia progression and ocular axial elongation in school children,and to provide a reference for the relevant prevention and control measures of myopia.@*Methods@#A total of 188 children with myopia were randomly assigned to the experimental group(93) or to the control group(95). During the phase (first 24 months) I,children received treatment in each eye once a day. During the phase II (from 25th to the 36th month),no treatment was given. Standardized eye examinations including spherical equivalent(SE),axial length(AL),intraocular pressure(IOP) and potential atropine-related side effect assessment were performed every 6 months.@*Results@#In phase I, the annual progression rates of equivalent spherical degree [(-0.35±0.21)D/year] and axial length [(0.11±0.07)mm/year] in the experimental group were significantly lower than those in the control group [(-0.83±0.26)D/year and (0.37±0.22)mm/year] (P<0.05). After withdrawal of atropine eye drops (phase II), the equivalent spherical degree progression rate [(-0.40±0.29)D/year] and axial length progression rate [(0.10±0.04)mm/year] in the experimental group were significantly lower than those in the control group [(0.73±0.40)D/year and (0.30±0.11)mm/year]. No serious adverse events associated with atropine were found during the follow up period. After the withdrawal of atropine, the pupil size, near visual acuity and adjustment gradually returned to the pre-treatment level.@*Conclusion@#0.05% atropine eye drops may not only maintain the efficacy and reduce potential side effects of atropine but also significantly increase the compliance of children,0.05% atropine is a safe and effective treatment for retarding myopic progression in moderate myopia.

ABSTRACT

Objective:To explore the clinical prognosis of early endarteritis (within 2 weeks) and late endarteritis (after 2 weeks) after renal transplantation.Methods:A total of 81 cases with higher creatinineand receiving renal biopsy after renal transplantation were recruited from September 2001 to December 2014. They were divided into early endarteritis group (n=43) and late endarteritis group (n=38). Baseline profiles, serum creatine, glomerular filtration rate (GFR) before and after treatment, steroid resistance, reversal rate, graft loss and survival rate were analyzed for two groups.Results:Early endarteritis group showed worse serum creatine and GFR than late endarteritis group before rejection. Early endarteritis group had a higher rate of treatment with steroid plus antibody (86 %) than that of late endarteritis group (86 %vs.18.6 %, P<0.05). No significant inter-group difference existed in graft loss (23.3 % vs.10.5 %, P=0.131). The survival curve of transplanted kidney showed no significant inter-group difference insurvival time. Conclusions:The status of patients with early simple endothelitis is significantly worse than that of those with late simple endothelitis. However, after active treatments, the prognosis of patients with early simple endothelitis is not inferior to that of those with late simple endothelitis.

ABSTRACT

Objective:To estimate the predictive performance of the population pharmacokinetics software JPKD-vancomycin on predicting the vancomycin steady-state trough concentration, and to analyze the related factors affecting the predictive performance.Methods:The clinical data of patients who were treated with vancomycin and received therapeutic drug monitoring (TDM) admitted to Suzhou Hospital Affiliated to Nanjing Medical University from July 2013 to December 2018 were enrolled. All patients were designed an empirical vancomycin regimen (initial regimen) according to vancomycin medication guidelines. Steady-state trough concentrations of vancomycin were determined at 48 hours after the first dose and 0.5 hour before the next dose. Dosage regimen was adjusted when steady-state trough concentration was not in 10-20 mg/L (adjustment regimen), and then the steady-state trough concentration was determined again 48 hours after adjustment. First, the JPKD-vancomycin software was used to calculate the initial regimen and predict the steady-state trough concentration according to the results calculated by classic pharmacokinetic software Vancomycin Calculator. Second, the JPKD-vancomycin software was used to adjust the vancomycin dosage regime and predict the steady-state trough concentration of adjustment regimen. The weight residual (WRES) between the predicted steady-state trough concentration (C pre) and the measured steady-state trough concentration (C real) was used to evaluate the ability of the JPKD-vancomycin software for predicting the vancomycin steady-state trough concentration. The TDM results of initial regimen were divided into accurate prediction group (WRES < 30%) and the inaccurate prediction group (WRES ≥ 30%) according to the WRES value. Patient and disease characteristics including gender, age, weight, height, the length of hospital stay, comorbidities, vasoactive agent, mechanical ventilation, smoking history, postoperative, obstetric patients, trauma, laboratory indicators, vancomycin therapy and TDM results were collected from electronic medical records. Univariate and multivariate Logistic regression analysis was used to screen the related factors that influence the predictive performance of JPKD-vancomycin software, and the receiver operating characteristic (ROC) curve was drawn to evaluate its predictive value. Results:A total of 310 patients were enrolled, and 467 steady-state trough concentrations of vancomycin were collected, including 310 concentrations of initial regimen and 157 concentrations of adjustment regimen. Compared with the initial regimen, the WRES of adjusted regimen was significantly reduced [14.84 (6.05, 22.89)% vs. 20.41 (11.06, 45.76)%, P < 0.01], and the proportion of WRES < 30% increased significantly [82.80% (130/157) vs. 63.87% (198/310), P < 0.01]. These results indicated that JPKD-vancomycin software had a better accuracy prediction for steady-state trough concentration of the adjusted regimen than the initial regimen. There were 198 concentrations in the accurate prediction group and 112 in the inaccurate prediction group. Univariate Logistic regression analysis showed that women [odds ratio ( OR) = 0.466, 95% confidence interval (95% CI) was 0.290-0.746, P = 0.002], low body weight ( OR = 0.974, 95% CI was 0.953-0.996, P = 0.022), short height ( OR = 0.963, 95% CI was 0.935-0.992, P = 0.014), low vancomycin clearance (CL Van; OR < 0.001, 95% CI was 0.000-0.231, P = 0.023) and postoperative patients ( OR = 1.695, 95% CI was 1.063-2.702, P = 0.027) were related factors affecting the predictive performance of JPKD-vancomycin software. Multivariate Logistic regression analysis indicated that women ( OR = 0.449, 95% CI was 0.205-0.986, P = 0.046), low CL Van ( OR < 0.001, 95% CI was 0.000-0.081, P = 0.015) and postoperative patients ( OR = 2.493, 95% CI was 1.455-4.272, P = 0.001) were independent risk factors for inaccurate prediction of JPKD-vancomycin software. The ROC analysis indicated that the area under ROC curve (AUC) of the CL Van for evaluating the accuracy of JPKD-vancomycin software in predicting vancomycin steady-state trough concentration was 0.571, the sensitivity was 56.3%, and the specificity was 57.1%. The predictive performance of JPKD-vancomycin software was decreased when CL Van was lower than 0.065 L·h -1·kg -1. Conclusions:JPKD-vancomycin software had a better predictive performance for the vancomycin steady-state trough concentrations of adjustment regimen than initial regimen. JPKD-vancomycin software had a poor predictive performance when the patient was female, having low CL Van, and was postoperative. The predictive performance of JPKD-vancomycin software was decreased when CL Van was lower than 0.065 L·h -1·kg -1.

ABSTRACT

Objective:To study the dynamic evaluation value of transcranial Doppler (TCD) in cerebral circulation and brain function of sepsis patients and its predictive value of the prognosis.Methods:A retrospective analysis was performed on 98 sepsis patients admitted to our hospital from January 2017 to June 2018 who were divided into the survival group (56 cases) and death group (42 cases) according to the 28-day prognosis. The general clinical data of the patients, acute physiology and chronic health evaluation II (APACHE II), delirium assessment scale (CAM-ICU), and TCD parameters PSV, Vm, EDV, PI, RI on the first day and the third day of admission were collected, and the differences of TCD parameters at different time points were analyzed between the two groups, the area under the ROC curve (AUC) was calculated and evaluating their predictive value of sepsis outcome was evaluated.Results:APACHE Ⅱscore and the number of patients with sepsis encephalopathy were significantly higher in the death group than those in the survival group ( P < 0.05). There were no significant differences in PSV, Vm and EDV between the two groups on the first day and the third day. The PI and RI of the survival group were significantly lower than those of the death group ( P<0.01). In the survival group, PI and RI on the third day decreased significantly compared with those on the first day ( P < 0.05), while in the death group, PI and RI on the first day and the third day did not change significantly. ROC survival curves showed that Day1PI, Day3PI, Day1PI - Day3PI, Day1RI, Day3RI, Day1RI - Day3RI and APACHEⅡ predicted AUC of the prognosis of sepsis patients were 0.657, 0.835, 0.730, 0.707, 0.826, 0.705, and 0.815 ( P < 0.01). When PI cutoff value on the third day became 1.02, the sensitivity was 85.7% and the specificity was 61.3%. When RI cutoff value on the third day became 0.62, the sensitivity was 78.6% and the specificity was 71.4%. Conclusions:TCD parameters, PI and RI, are of certain value in the dynamic evaluation of cerebral circulation and brain function in sepsis patients. PI and RI on the first day and the third day and the differences between them are all valuable in predicting the prognosis, and PI and RI on the third day have greater predictive value.

ABSTRACT

Objective To analyze the epidemiological characteristics of hepatitis B in Guangzhou from 2006 to 2018. Methods The data were retrieved from the National Infectious Disease Surveillance Information Report Management System. Descriptive methods were used to analyze and summarize the results. Chi-square test was used for statistical analysis of classification data, and Joinpoint software was used to analyze the annual change percentage and trend. Results A total of 292 674 cases of hepatitis B were reported in Guangzhou from 2006 to 2018, and the annual average reported incidence was 182.2 per 100,000. Chronic hepatitis B was the main type, accounting for 89.9%. The incidence rate of males (241.6 / 105) was higher than that of females (117.9 / 105), with a ratio of 2.0:1. During the period from 2006-2018, the reported incidence of hepatitis B in Guangzhou first increased, reached the highest in 2008, and then decreased year by year. There was no significant difference in the number of HBV cases among different months. The average onset age of hepatitis B reported in Guangzhou was 39.3 years old, and the average onset age increased year by year from 2006 to 2018. Conclusion The incidence rate of hepatitis B in Guangzhou has decreased since 2008, but it was still higher than the national average incidence rate. The hepatitis B infection in Guangzhou remains a big issue. It is suggested to further strengthen the prevention and control of hepatitis B in adults by maintaining a national immunization program for children, thereby reducing the epidemiological level of hepatitis B in Guangzhou.

ABSTRACT

OBJECTIVE@#To study the influence of maternal sex chromosomal abnormalities on the prediction of fetal sex chromosome abnormalities (SCAs) by non-invasive prenatal testing (NIPT).@*METHODS@#Thirty-six pregnant women with a prediction for fetal SCAs by NIPT were verified as false positive after prenatal diagnosis using amniotic fluid samples. With informed consent, these women were subjected to chromosomal karyotyping or copy number variations (CNVs) analysis through high-throughput sequencing.@*RESULTS@#Sex chromosomal abnormalities were found in 8 women, which yielded an abnormal rate of 22.22% (8/36). Among these, 3 had sex chromosome aneuploidies (47, XXX), 4 had sex chromosome mosaicisms, and 1 carried structural chromosomal abnormalities. Reanalysis of the results of NIPT were consistent with the maternal CNVs by large. With the ratio of cffDNA (ChrX)/cffDNA was more than 2, 6 of the eight women were found to harbor sex chromosome abnormalities, and the fetal karyotype was normal. However, with a ratio of less than 2, only 2 of the 38 pregnant women had sex chromosome abnormalities, and 10 of the fetuses were confirmed as positive.@*CONCLUSION@#The presence of maternal sex chromosomal abnormalities can greatly influence the result of NIPT, which may also be an important reason for false prediction for fetal SCAs by NIPT. When NIPT indicates abnormal SCAs, it is necessary to analyze maternal sex chromosomes. The ratio of cffDNA(ChrX)/cffDNA may help to determine the source of abnormal signals.

ABSTRACT

Objective To explore the clinical characteristics of autoimmune disease with dual seropositive antibodies of leucine-rich glioma inactivated 1(LGI1)and contactin-associated protein 2(Caspr2).Methods The clinical data of seven patients with dual seropositive LGI1 and Caspr2 antibodies who were admitted to the Neurology Department of Peking Union Medical College Hospital from July 2014 to December 2017 were retrospectively analyzed.Results Central,peripheral and autonomic nervous systems were all involved in the seven cases;100%(7/7)presented with insomnia,myokymia,neuropahic pain and hyperhydrosis;71%(5/7)showed memory decline or psychiatric and behavioral symptoms;57%(4/7)had urinary hesitation or constipation;and 43%(3/7)had seizure.Electromyography showed 100%(6/6) of the patients had prolonged afterdischarges following normal M waves and/or abnormal spontaneous firing.Electroencephalography revealed slow waves or basic rhythm slowing in 71%(5/7)of patients.Electrocardiography showed sinus tachycardia,axis deviation,and prolonged QT intervals in 71%(5/7)of patients.One patient died from arrhythmia before immunotherapy.One died from pulmonary infection after immunotherapy.Improvement with immunotherapy was documented in the other five cases.No relapse was noted during the 1-2-year follow-up.Conclusions Autoimmune disease with dual seropositive antibodies of LGI1 and Caspr2 can diffusely affect the central,peripheral,and autonomic nervous systems.The possibility of this disease should be considered in patients with acute and subacute onset of neuropsychiatric symptoms,especially in patients with accompanying insomnia,myokymia,and hyperhydrosis.

ABSTRACT

Objective:To observe effect of Zeqi Tang in intervening mice with orthotopic lung cancer model, in order to observe its anti-tumor mechanism. Method:An in situ mouse model of non-small cell lung cancer was established through intrapulmonary injection with 1×105 LLC-luc cells. The model mice were intragastrically administered with Zeqi Tang(0.171 g·mL-1) or normal saline for 35 days. Appearance (spirit, hair, appetite, sleep), survival period and Zeqi Tang anti-tumor effect were observed, weekly vital imaging was performed to detect the fluorescence signal in the lungs of mice. Flow cytometry was used to detect the NK cell content in the spleen of the model mice. CD107α was used to detect the degranulation of NK cells in the spleen of mice after administration of Zeqi Tang. Kromasil 100 5 C18 column was used and eluted with acetonitrile-0.025%phosphoric acid in a gradient mode, with flow rate at 1.0 mL·min-1, column temperature at 35℃ and detection wavelength of 265 nm, as to establish the fingerprint of Zeqi Tang. The fingerprints of 10 batches of samples was evaluated by using the Chinese Medicine Chromatographic Fingerprint Similarity Evaluation System Software (2012 Edition) recommended by the Chinese Pharmacopoeia Commission, in order to complete the quality control of Zeqi Tang. Result:Zeqi Tang could significantly inhibit the lung fluorescence signal of lung cancer in situ model mice and prolong the survival of mice(PPPα also increased significantly(PConclusion:Zeqi Tang may enhance the tumor growth and prolong the survival period of mice by up-regulating the number of NK cells in mice and enhancing their degranulation function. The evaluation of similarity of HPLC fingerprint of Zeqi Tang reflects the quality of lacquer soup to a certain extent, and can provide reference for further study.
