OBJECTIVES: To investigate the risk factors for neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture and establish a nomogram model for predicting the risk of neonatal asphyxia. METHODS: A retrospective study was conducted with 613 cases of neonatal asphyxia treated in 20 cooperative hospitals in Enshi Tujia and Miao Autonomous Prefecture from January to December 2019 as the asphyxia group, and 988 randomly selected non-asphyxia neonates born and admitted to the neonatology department of these hospitals during the same period as the control group. Univariate and multivariate analyses were used to identify risk factors for neonatal asphyxia. R software (4.2.2) was used to establish a nomogram model. Receiver operator characteristic curve, calibration curve, and decision curve analysis were used to assess the discrimination, calibration, and clinical usefulness of the model for predicting the risk of neonatal asphyxia, respectively. RESULTS: Multivariate logistic regression analysis showed that minority (Tujia), male sex, premature birth, congenital malformations, abnormal fetal position, intrauterine distress, maternal occupation as a farmer, education level below high school, fewer than 9 prenatal check-ups, threatened abortion, abnormal umbilical cord, abnormal amniotic fluid, placenta previa, abruptio placentae, emergency caesarean section, and assisted delivery were independent risk factors for neonatal asphyxia (P<0.05). The area under the curve of the model for predicting the risk of neonatal asphyxia based on these risk factors was 0.748 (95%CI: 0.723-0.772). The calibration curve indicated high accuracy of the model for predicting the risk of neonatal asphyxia. The decision curve analysis showed that the model could provide a higher net benefit for neonates at risk of asphyxia. CONCLUSIONS The risk factors for neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture are multifactorial, and the nomogram model based on these factors has good value in predicting the risk of neonatal asphyxia, which can help clinicians identify neonates at high risk of asphyxia early, and reduce the incidence of neonatal asphyxia.

In this study, a high performance thin-layer chromatography/single quadrupole mass spectrometry QDa (HPTLC-QDa) method for robust authentication of Ganoderma lucidum, a popular and valuable herbal medicine, has been developed. This method is simple and practical, which allows direct generation of characteristic mass spectra from the HPTLC plates automatically with the application of in situ solvent desorption interface. The HPTLC silica gel plates were developed with toluene-ethyl formate-formic acid (5 : 5 : 0.2, V/V) and all bands were transferred to QDa system directly in situ using 80% methanol with 0.1% formic acid as desorption solvent. The acquired HPTLC-QDa spectra showed that luminous yellow band b3, containing ganoderic acid B/G/H and ganodeneric acid B, the major active components of Ganoderma, could be found only in G. lucidum and G. lucidum (Antler-shaped), but not in G. sinense and G. applanatum. Moreover, bands b13 and b14 with m/z 475/477 and m/z 475/491/495, respectively, could be detected in G. lucidum (Antler-shaped), but not in G. lucidum, thus allowing simple and robust authentication of G. lucidum with confused species. This method is proved to be simple, practical and reproducible, which can be extended to analyze other herbal medicines.

Objective: Analysis of the effect of triggering receptor-1 expressed on myeloid cells (TREM-1) in nonalcoholic fatty liver disease (NAFLD) and the mechanism. Methods: The oleic acid-treated HepG2 cells were divided into model group, overexpression group, interference group A, interference group B and negative control group. The mouse model of NAFLD was generated and randomly divided into (nuclear factor-κB) NF-κB inhibition group, protein kinase B (AKT) inhibition group, knockout group A, knockout group B and control group. The expression of inflammatory factors and TREM-1 in liver tissue was detected by PCR, and fat accumulation was detected by oil red O staining. Western blotting was used to detect the expression of TREM-1 and signaling pathway proteins, and HE staining was used to detect liver tissue changes. Results: TREM-1 was up-regulated in liver tissue of NAFLD mice [(0.936±0.127) vs. (0.432±0.105)] and in oleic acid-treated HepG2 cells. In oleic acid-treated HepG2 cells, overexpression of TREM-1 increased inflammatory factor expression and increased lipid droplets; inhibition of TREM-1 expression decreased inflammatory factor expression, and lipid droplets decreased. Knockout of TREM-1 and inhibition of NF-κB in NAFLD mice reduced hepatocyte inflammatory factor expression and reduced liver damage; knockout of TREM-1 and inhibition of AKT reduced liver tissue lipids and drops accumulate. Conclusions The overexpression of TREM-1 in NAFLD mice liver tissue can regulate inflammatory factor expression and lipid droplets through NF-κB and AKT signal pathway. TREM-1 might be a potential therapeutic target of NAFLD.

Aim To prepare evodiamine butyryl deriva-tive (EBD) and evodiamine butyryl derivative-loaded solid lipid nanoparticles (EBDLN), and study its re-lease in vitro,and to investigate its in situ gastrointesti-nal absorption. Methods EBD was prepared by a one-step synthetized method, and then EBDLN was prepared by a film dispersion method. Dynamic dialy-sis was used to evaluate drug release in vitro,and sin-gle-pass gastrointestinal perfusion was employed to study the gastrointestinal absorption of EDM,EBD and EBDLN. Results In identical release media, there were identical drug release tendencies of EBD and EB-DLN, but the release rate of EBDLN was faster than EBD. Compared with EDM and EBD, the Kavalues and Pappvalues of EBDLN in every perfusion segment increased significantly. The Kaof EBDLN in stomach, duodenum, jejunum, ileum and colon was 110.14-fold,56.70-fold,51.23-fold,45.70-fold and 127.23-fold of free EDM respectively. The Pappvalue of EB-DLN was 9.74-fold, 4.48-fold, 3.82-fold and 11.3-fold of that of free EDM. Conclusion EBDLN has sustained effect and can enhance the gastrointestinal absorption of EDM and EBD.

BACKGROUNDThe management of pain, agitation, and delirium (PAD) in Intensive Care Unit (ICU) is beneficial for patients and makes it widely applied in clinical practice. Previous studies showed that the clinical practice of PAD in ICU was improving; yet relatively little information is available in China. This study aimed to investigate the practice of PAD in ICUs in China.

METHODSA multicenter, nationwide survey was conducted using a clinician-directed questionnaire from September 19 to December 18, 2016. The questionnaire focused on the assessment and management of PAD by the clinicians in ICUs. The practice of PAD was compared among the four regions of China (North, Southeast, Northwest, and Southwest). The data were expressed as percentage and frequency. The Chi-square test, Fisher's exact test, and line-row Chi-square test were used.

RESULTSOf the 1011 valid questionnaire forms, the response rate was 80.37%. The clinicians came from 704 hospitals across 158 cities of China. The rate of PAD assessment was 75.77%, 90.21%, and 66.77%, respectively. The rates of PAD scores were 45.8%, 68.94%, and 34.03%, respectively. The visual analog scale, Richmond agitation-sedation scale, and confusion assessment method for the ICU were the first choices of scales for PAD assessment. Fentanyl, midazolam, and dexmedetomidine were the first choices of agents for analgesic, sedation, and delirium treatment. While choosing analgesics and sedatives, the clinicians put the pharmacological characteristics of drugs in the first place (66.07% and 76.36%). Daily interruption for sedation was carried out by 67.26% clinicians. Most of the clinicians (87.24%) used analgesics while using sedatives. Of the 738 (73%) clinicians titrating the sedatives on the basis of the proposed target sedation level, 268 (26.61%) clinicians just depended on their clinical experience. Totally, 519 (51.34%) clinicians never used other nondrug strategies for PAD. The working time of clinicians was an important factor in the management of analgesia and sedation rather than their titles and educational background. The ratios of pain score and sedation score in the Southwest China were the highest and the North China were the lowest. The ratios of delirium assessment and score were the same in the four regions of China. Moreover, the first choices of scales for PAD in the four regions were the same. However, the top three choices of agents in PAD treatment in the four regions were not the same.

CONCLUSIONSThe practice of PAD in China follows the international guidelines; however, the pain assessment should be improved. The PAD practice is a little different across the four regions of China; however, the trend is consistent.

INTRODUCTIONHepatitis B virus (HBV) reactivation has been reported in B-cell lymphoma patients with resolved hepatitis B (hepatitis B surface antigen [HBsAg]-negative and hepatitis B core antibody [HBcAb]-positive). This study aimed to assess HBV reactivation and hepatitis occurrence in diffuse large B-cell lymphoma (DLBCL) patients with resolved hepatitis B receiving rituximab-containing chemotherapy compared with HBsAg-negative/HBcAb-negative patients to identify risk factors for HBV reactivation and hepatitis occurrence and to analyze whether HBV reactivation and hepatitis affect the survival of DLBCL patients with resolved hepatitis B.

METHODSWe reviewed the clinical data of 278 patients with DLBCL treated with rituximab-containing therapy between January 2004 and May 2008 at Sun Yat-sen University Cancer Center, China. Predictive factors for HBV reactivation, hepatitis development, and survival were examined by univariate analysis using the chi-square or Fisher's exact test and by multivariate analysis using the Cox regression model.

RESULTSAmong the 278 patients, 165 were HBsAg-negative. Among these 165 patients, 6 (10.9%) of 55 HBcAb-positive (resolved HBV infection) patients experienced HBV reactivation compared with none (0%) of 110 HBcAb-negative patients (P = 0.001). Patients with resolved hepatitis B had a higher hepatitis occurrence rate than HBsAg-negative/HBcAb-negative patients (21.8% vs. 8.2%, P = 0.013). HBcAb positivity and elevated baseline alanine aminotransferase (ALT) levels were independent risk factors for hepatitis. Among the 55 patients with resolved hepatitis B, patients with elevated baseline serum ALT or aspartate aminotransferase (AST) levels were more likely to develop hepatitis than those with normal serum ALT or AST levels (P = 0.037, P = 0.005, respectively). An elevated baseline AST level was an independent risk factor for hepatitis in these patients. Six patients with HBV reactivation recovered after immediate antiviral therapy, and chemotherapy was continued. HBcAb positivity, HBV reactivation, or hepatitis did not negatively affect the survival of DLBCL patients.

CONCLUSIONSDLBCL patients with resolved hepatitis B may have a higher risk of developing HBV reactivation and hepatitis than HBsAg-negative/HBcAb-negative patients. Close monitoring and prompt antiviral therapy are required in these patients.

OBJECTIVETo evaluate the effectiveness of Shenqi Fuzheng Injection (, SFI) combined with chemotherapy for advanced gastric cancer.

METHODSRandomized controlled trials (RCTs) from 10 databases were searched for this meta-analysis till December 31, 2012 without language restriction. Grey literature and potential unpublished literature was also searched. The key search terms were "chemotherapy", "Shenqi Fuzheng Injection" and "advanced gastric cancer". Criteria were built to select these clinical trials, in which SFI combined with chemotherapy was compared with chemotherapy alone for advanced gastric cancer. The methodological quality of each RCT was assessed using the Cochrane risk of bias tool. RevMan 5.1 software was applied for data analyses.

RESULTSThirteen RCTs involving 860 patients met the selection criteria (all articles were from Chinese databases). The meta-analysis showed positive results for the use of SFI combined with chemotherapy according to quality of life in terms of the scores when compared with chemotherapy alone. Positive results were also obtained for the combination treatment, in terms of complete remission and partial remission efficacy rate, body weight and decreased adverse events including nausea and vomiting at grade 3-4, oral mucositis at grade 1-2, leucopenia at grade 3-4, and myelo-suppression at grade 1-2.

CONCLUSIONSThis systematic review found encouraging albeit limited evidence for SFI combined with chemotherapy. However, to obtain stronger evidence without the drawbacks of trial design and the quality of studies, we recommend comparative effectiveness researches to test the effectiveness of combination treatment.

OBJECTIVETo investigate the effects of hypoxia during the prenatal period and its later repercussions on sexual behavior and the sex hormone secretion of male rats.

METHODSExperimental animals were divided into three groups randomly: control group, which was kept at normal atmospheric pressure, and two stress groups exposed to a simulated altitude equivalent to 3000 m and 5000 m, respectively. Stress groups were exposed to hypoxic circumstance at their final week of gestation in animal decompression chamber.

RESULTSAdulthood, males exposed to hypoxic stress during the prenatal period were able to mate with normal females, but these treated males exhibited decreased male sexual behavior. Decreased anogenital distances were observed in male offspring, and presented reductions of plasma testosterone levels, increase of plasma corticosterone levels, but no notable alteration in the organ index.

CONCLUSIONThese results indicate that exposure to hypoxia in the later stages of pregnancy may have a long-term effect on the fertility and sexual behavior of male offspring.
