ObjectiveTo evaluate the reliability and validity of the Dampness Syndrome Scale of Chinese Medicine （DSSCM） among patients with persistent asthma， and to explore the correlation between dampness syndrome and clinical characteristics of persistent asthma. MethodsA cross-sectional survey was conducted. Basic information， examination results， DSSCM， Asthma Control Test （ACT）， Generalized Anxiety Disorder-7 （GAD-7）， and Patient Health Questionnaire-9 （PHQ-9） scores were collected from 206 patients with persistent asthma to evaluate the reliability and validity of DSSCM and to explore the correlation between dampness syndrome and clinical characteristics. ResultsThe mean score of DSSCM among 206 patients was 14.59 ± 10.53. The overall Cronbach α coefficient and Spearman-Brown split-half reliability coefficient of the scale were both greater than 0.8， and the success rate of scale convergent and discriminant validity calibration were greater than 80%. The confirmatory factor analysis showed that the χ²/df was 2.309， and the root mean square error of approximation （RMSEA） was 0.08； the root mean square residual （RMR） was 0.049， whereas the comparative fit index （CFI）， the goodness of fit index （GFI）， the adjusted goodness of fit index （AGFI）， the normed fit index （NFI） and the incremental fit index （IFI） were less than 0.9. Correlation analysis showed that DSSCM scores were positively correlated with disease duration， GAD-7 scores， and PHQ-9 scores （P＜0.05）， and negatively correlated with ACT scores （P＜0.01）. The DSSCM scores were significantly different between patients with different disease severity （H = 10.92， P = 0.01）， and the DSSCM scores of allergic patients were higher than those of non-allergic patients （Z = -4.19， P＜0.001）. ConclusionDSSCM has acceptable reliability and validity for patients with persistent asthma. The scores of DSSCM correlated with the disease duration， ACT score， GAD-7 score， PHQ-9 score， disease severity and allergic status of persistent asthmatics.

Objective:To explore the current situation of fear of progression among parents of school-age children with asthma, and to analyze the latent profile categories and influencing factors, so as to provide the reference for the formulation of prevention and intervention.Methods:Using convenient sampling method, school-age children with asthma and their parents treated in the Affiliated Children's Hospital of Xiangya School of Medicine, Central South University from March to August 2023 were selected as the study objects. The General Data Questionnaire, Parent Fear of Progression Scale, Childhood Asthma Control Test, and Social Support Rating Scale were used to investigate school-age children with asthma and their parents. Latent profile analysis was performed on the fear of disease progression among parents of school-age children with asthma, and χ2 test and binary Logistic regression were used to explore the influencing factors. Results:A total of 210 parents of the children were included with 51 fathers and 159 mothers.The age distribution was 20-30 years old with 42 parents, 31-40 years old with 112 parents, 41-50 years old with 56 parents. In 210 children with asthma, there were 123 males and 87 females, with 141 cases aged<10 years old and 69 cases aged ≥10 years old. The fear of progression among parents of school-age children with asthma could be divided into two potential profile categories: "psychological dysfunction group (46.7%, 98/210)" and "psychological health good group (53.3%, 112/210)". The results of binary Logistic regression analysis showed that asthma family history, combined allergic rhinitis, child-parent relationship, marital status, asthma symptom control level, and social support level were the influencing factors of fear of progression among parents of school-age children with asthma( OR values were 0.925-10.010, all P<0.05). Conclusions:The fear of progression among parents of school-age children with asthma is at a moderate level, and there are obvious different classification characteristics. In the future, targeted and precise prevention and intervention should be implemented according to the category characteristics of fear of progression among parents of school-age children with asthma.

A novel amide alkaloid,bursatamide A(1),featuring an unprecedented propyl-hexahydronaphthalene carbon frame-work,was isolated from the infrequently studied sea hare Bursatella leachi,alongside a new 3-phenoxypropanenitrile alkaloid,bursatellin B(2),and twelve known compounds.The structures of 1 and 2 were elucidated through comprehensive spectroscopic data analyses,while their relative and absolute configurations(ACs)were established through total synthesis and a series of quantum chem-ical calculations,including calculated electronic circular dichroism(ECD)spectra,optical rotatory dispersion(ORD)methods,and DP4+probability analyses.Bursatamide A(1)demonstrated inhibitory effects against the human pathogenic bacteria Listeria monocyt-ogenes and Vibrio cholerae.Erythro-bursatellin B(21),a diastereoisomer of 2,exhibited notable antibacterial activity against the fish pathogenic bacterium Streptococcus parauberis FP KSP28,with an MIC90 value of 0.0472 μg·mL-1.

Objective:To design a pediatric early warning score (PEWS) ruler and observe the effect of its application in the nursing of critically ill children hospitalized in neurology department.Methods:A total of 200 critically ill children admitted to Department of Neurology of Hunan Children′s Hospital from 2018 to 2019. 98 cases who were hospitalized from January to September 2019 were selected as the observation group, and 102 cases who were hospitalized from January to September 2018 were set as the control group. The control group received conventional care, while the observation group conducted PEWS ruler for nursing intervention on the basis of conventional care. The differences in hospital days, ICU transfer rate, and frequency of medical intervention between the two groups were compared.Results:The hospital days of the control group and observation group were 18.17 ± 6.33 and 13.33 ± 6.38 respectively, and the difference between the two groups was significant ( t=5.38, P<0.01). The ICU transfer rate was significantly different between the control group 17.6% (18/102) and observation group 8.2% (8/98) ( χ2=3.98, P<0.05). The reduction of increased intracranial pressure, cooling, calm, sedation and oxygen breathing in the control group were 6.86% (7/102), 13.73% (14/102), 6.86% (7/102), 7.84% (8/102), while the observation group were 17.35% (17/98), 27.55% (27/98), 24.49% (24/98), 28.57% (28/98), and the differences between the two groups were significant ( χ2 values were 5.20-14.55, all P<0.05). Conclusions:The application of PEWS ruler is helpful for nurses to recognize the progress of diseases of the critically ill children. Also, it can shorten the hospitalization days of these children, reduce the ICU transfer rate, as well as improve the nursing quality for them.

Schizophyllum commune has emerged as the most promising model mushroom to study developmental stages (mycelium, primordium), which are two primary processes of fruit body development. Long non-coding RNA (lncRNA) has been proved to participate in fruit development and sex differentiation in fungi. However, potential lncRNAs have not been identified in S. commune from mycelium to primordium developmental stages. In this study, lncRNA-seq was performed in S. commune and 61.56 Gb clean data were generated from mycelium and primordium developmental stages. Furthermore, 191 lncRNAs had been obtained and a total of 49 lncRNAs were classified as differently expressed lncRNAs.Additionally, 26 up-regulated differently expressed lncRNAs and 23 down-regulated between mycelium and primordia libraries were detected. Further, Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis showed that differentially expressed lncRNAs target genes from the MAPK pathway, phosphatidylinositol signal, ubiquitin-mediated proteolysis, autophagy, and cell cycle. This study provides a new resource for further research on the relationship between lncRNA and two developmental stages (mycelium, primordium) in S. commune

Objective To investigate the application value of dynamic single-photon emission computed tomography (SPECT) 99m-technetium galactosyl human serum albumin diethylenetriamine pentaacetic acid injection (99 Tcm-GSA) scintigraphy assessing regional liver function changes before and after portal vein embolization (PVE).Methods The retrospective cross-sectional study was conducted.The clinical data of 11 patients with Bismuth Ⅲ a hilar cholangiocarcinoma who were admitted to the General Hospital of People's Liberation Army (10 patients) and Beijing Tsinghua Changgung Hospital (1 patient) from October 2010 to October 2016 were collected.B ultrasound-guided percutaneous transhepatic ipsilateral exbolization was performed before radical resection of hilar cholangiocarcinoma.Dynamic SPECT 99 Tcm-GSA scintigraphy was performed to calculate and compare the changes of functional liver volume (FLV),morphological liver volume (MLV) and functional liver density (FLD) in embolized lobe and non-embolized lobe before PVE and 2 weeks after PVE.Observation indicators:(1) the changes of serum indexes in 2 weeks before and after PVE;(2) the changes of FLV,MLV and FLD in the whole liver,embolized and non-embolized lobes in 2 weeks before and after PVE;(3) surgical and postoperative situations of hilar cholangiocarcinoma;(4) follow-up and survival situations.Follow-up using outpatient examination and telephone interview was performed to detect postoperative serum toal bilirubin (TBil) level,with or without peritoneal effusion and survival up to June 2017.Measurement data with normal distribution were represented as x-±s.The comparisons of pre-and post-operative data were analyzed by the paired t test.Results (1) The changes of serum indexes in 2 weeks before and after PVE:11 patients underwent successful right PVE.The alanine aminotransferase (ALT),TBil,albumin (Alb),Platelets (PLT) and prothrombin time (PT) were respectively (113±20) U/L,(73± 8) μmol/L,(35.0±2.5) g/L,(209±58) × 109/L,(11.4±0.7) seconds in 2 weeks before PVE and (120± 18) U/L,(36± 7) μmol/L,(34.4± 3.2) g/L,(224± 82) × 109/L,(11.2±0.8)seconds in 2 weeks after PVE,with a statistically significant difference in TBil level (t=-10.592,P＜0.05) and no statistically significant difference in ALT,Alb,PLT and PT (t=0.981,-0.350,-0.591,0.533,P＞0.05).(2) The changes of FLV,M LV and FLD in the whole liver,embolized and nonembolized lobes in 2 weeks before and after PVE:the FLV,MLV and FLD of the whole liver were respectively (894±255) mL,(1 552±504) mL,0.59±0.14 in 2 weeks before PVE and (812±206) mL,(1 521±422) mL,0.55±0.16 in 2 weeks after PVE,with no statistically significant difference (t =1.569,0.666,1.980,P＞ 0.05).The FLV,MLV and FLD of the embolized lobe were respectively (623±275) mL,(1 047± 394) mL,0.62±0.14 in 2 weeks before PVE and (375±240) mL,(865±337) mL,0.44±0.24 in 2 weeks after PVE,with statistically significant differences (t =5.909,3.736,3.359,P ＜ 0.05);the descending percentages were respectively 38.1％,9.8％ and 24.6％.The FLV,MLV and FLD of the non-embolized lobe were respectively (274±152)mL,(530±176)mL,0.52±0.21 in 2 weeks before PVE and (436±149) mL,(656±133)mL,0.68± 0.24 in 2 weeks after PVE,with statistically significant differences (t =-6.019,-6.345,-3.933,P＜0.05);the elevated percentages were respectively 80.1％,19.9％ and 23.8％.(3) Surgical and postoperative situations of hilar cholangiocarcinoma:of 11 patients,10 received successful peri-hilar right hemihepatectomy,the right hepatic atrophy and an obvious demarcation line between left and right liver were found intraoperatively;1 stopped operation due to detect intraoperatively peritoneal metastasis of tumor.The operation time,volume of intraoperative blood loss and time of postoperative abdominal drainage-tube removal were respectively (585± 194)minutes,(472± 274)mL and (8±5)days.Of 10 patients undergoing operations,2 were complicated with massive peritoneal effusion at 2 days postoperatively,volume of peritoneal effusion remained more than 500 mL up to 7 days after drainage,and were improved by 1-month conservative treatment;other 8 patients were not complicated with hepatic dysfunction.Duration of hospital stay of 11 patients was (16± 4) days.(4) Follow-up and survival situations:10 patients were followed up for 4-72 months,with a median time of 39 months.During the follow-up,there was no evaluated TBil level and peritoneal effusion in 10 patients.The median survival time,1-,3-and 5-year overall survival rates were 88.8％,74.6％ and 36.8％,respectively.Conclusions The dynamic SPECT 99Tcm-GSA scintigraphy can effectively evaluate liver function changes of embolized and non-embolized lobes before and after PVE.The increased rate of FLV of non-embolized lobe is higher than that of MLV.

Objective: To evaluate the prognostic value of ¹⁸F-fluorodeoxyglucose positron emission tomography (PET)/computed tomography (CT) in patients with diffuse large B cell lymphoma (DLBCL) undergoing autologous hematopoietic stem cell transplantation (auto-HSCT). Methods: Forty-eight patients with DLBCL treated at Peking University Cancer Hospital between November 2010 and December 2014 were assessed. All patients underwent PET/CT scanning prior to or after auto-HSCT. Correlation analysis was done based upon patients characteristics, PET/CT scan results and survival. Results: ①Among 48 patients, 27 was male, 21 female, median age was 43 (17-59) years old. ② Patients with negative pre-auto-HSCT PET/CT assessment demonstrated significantly better 3-year progression free survival (PFS) (87.1% vs 53.3%, χ²=7.02, P=0.019) and overall survival (OS) (90.3% vs 60.0%, χ²=6.51,P=0.022) than patients with positive pre-auto-HSCT PET/CT assessment. Three-year PFS (94.1% vs 30.0%, χ²=22.75, P=0.001) and OS (97.1% vs 40.0%, χ²=21.09, P=0.002) were also significantly different between patients with negative and positive post-auto-HSCT PET/CT assessment. ③ Multivariate analysis indicated a significant association of PFS (HR=13.176, P=0.005) and OS (HR=20.221, P=0.007) with post-auto-HSCT PET/CT assessment. Number of prior treatment regimens was associated with PFS (HR=10.039, P=0.040). ④ Harrell’s C index revealed that the value of combined use of number of prior treatment regimens and post-auto-HSCT PET/CT assessment was superior to either one used alone in PFS (Harrell’s C values were 0.976, 0.869 and 0.927 in combined use, number of prior treatment regimens and post-auto-HSCT PET/CT assessment, respectively), and the combined use of ECOG performance status and post-auto-HSCT PET/CT assessment significantly increased the Harrell’s C index in OS (Harrell’s C values were 0.973, 0.711 and 0.919 in combined use, ECOG performance status and post-auto-HSCT PET/CT assessment, respectively). Conclusions Post-auto-HSCT PET/CT assessment is the main predictor of outcomes in DLBCL patients receiving auto-HSCT. Combined use of post-auto-HSCT PET/CT assessment and number of prior treatment regimens and ECOG performance status is a better prognostic tool in patients with DLBCL undergoing transplantation.

Objective To evaluate the Effect of dexmedetomidine on the stress reaction for awake nasotra-cheal intubation in patients with maxillofacial tumor. Methods Forty patients,which are ASA physical status Ⅰor Ⅱ,aged 20 ~ 62 yr ,BMI < 25 and scheduled for radical operation for maxillofacial tuomr ,were randomly divided into 2 groups (n = 20 each)using a random number table:dexmedetomidine groups(group D)and mid-azolam group(group M). MAP ,HR ,SpO2 were recorded ,and the rate of respiratory depression ,the degree of tolerance and matching and the memory to intubation were recorded. Results Compared with the baseline value at T0,MAP and HR at T1-2 and HR at T3 were increased in group M. HR were increased at T1 in group D(P<0.05). Compared with group M,MAP and HR at T1-2 and HR at T3 were decresed in group D(P<0.05). The rate of respi-ratory depression in group D was decreased compared with group M ,and the degree of tolerance and matching to intubation was better in group D. Conclusion dexmedetomidine can inhibit the stress reaction caused by nasotra-cheal intubation in patients with maxillofacial tuomr ,and improve the degree of comfort and security in the process of intubation.

Objective To investigate the clinical value of combination of transvaginal fourdimensional hysterosalpingo-contrast sonography(TVS 4D-HyCoSy) with uterine tubal liquid poking in assessment tubal fimbria patency.Methods Sixty-two female infertile patients with obstruction at tubal fimbria,or partial obstruction with pelvic adhesion were included.All of them were underwent 4D-HyCoSy as well as uterine tubal liquid poking,and were followed with laparoscopic chromopertubation (LPC) using Methylene blue in three months.Results Comparing with laparoscopy,the total coincidence rate of 4D-HyCoSy to assess the tubal fimbria patency was 94.3％,with the sensitivity of 90.1％ and specificity of 94.1 ％.Imaging results showed that the obstruction at tubal fimbria,uncircle-like wrapping contrast medium can be seen around ovary accounted for 80％.The patent fallopian tube fimbria,circle-like wrapping of contrast medium can be observed around ovary accounted for 85.5 ％.Conclusions The combination of TVS 4D-HyCoSy with uterine tubal liquid poking is highly in accordance with LPC by providing real-time dynamic visualization on overflowing of contrast medium from tubal fimbria,as well as the pelvic adhesion surrounding ovaries.The 4D-HyCoSy can be the preferred method for assessment of tubal fimbria patency and pelvic adhesion surrounding ovaries with its advantages of accuracy,non invasion and a good safety profile.

Objective To investigate the current status of preoperative skin preparation in abdominal surgery in China,and put forward suggestions for improvement.Methods From April to May,2016,187 secondary and above hospitals in China were selected,questionnaires were used to investigate the methods for hair removal,skin disinfection on operative field,and application of surgical adhesive drape in abdominal surgery.Results A total of 187 hospitals in 14 provinces were investigated,of which 108 and 79 were tertiary and secondary hospitals respec-tively.87.70% of hospitals performed conventional preoperative hair removal in abdominal surgery,the percentage of conventional depilation in secondary hospitals was higher than tertiary hospitals(93.67% vs 83.33%,χ2 =4.520,P =0.033).85.98% of hospitals selected blade-shaving,7.93% and 23.78% applied chemical depilation and electric depilation respectively.Most hospitals (98.17%)performed skin preparation in the wards,mainly by ward nurses (98.17%),and conducted on the day of surgery (56.10%).86.63%,29.95%,and 3.74% of hospi-tals used iodophor,iodine plus alcohol,and chlorhexidine respectively for disinfecting skin on operative field. 92.51% of hospitals used skin incision/surgical adhesive drape (74.57% used selectively).Conclusion Most hos-pitals in China conventionally perform preoperative hair removal in abdominal surgery,and the primary method for depilation is blade-shaving,nearly half of the hospitals performed depilation on the day of surgery.Iodophor is the major skin antiseptic,surgical adhesive drape is widely used,but it is utilized in limited types of surgery.
