Objective Viral encephalitis is an infectious disease severely affecting human health.It is caused by a wide variety of viral pathogens,including herpes viruses,flaviviruses,enteroviruses,and other viruses.The laboratory diagnosis of viral encephalitis is a worldwide challenge.Recently,high-throughput sequencing technology has provided new tools for diagnosing central nervous system infections.Thus,In this study,we established a multipathogen detection platform for viral encephalitis based on amplicon sequencing. Methods We designed nine pairs of specific polymerase chain reaction(PCR)primers for the 12 viruses by reviewing the relevant literature.The detection ability of the primers was verified by software simulation and the detection of known positive samples.Amplicon sequencing was used to validate the samples,and consistency was compared with Sanger sequencing. Results The results showed that the target sequences of various pathogens were obtained at a coverage depth level greater than 20×,and the sequence lengths were consistent with the sizes of the predicted amplicons.The sequences were verified using the National Center for Biotechnology Information BLAST,and all results were consistent with the results of Sanger sequencing. Conclusion Amplicon-based high-throughput sequencing technology is feasible as a supplementary method for the pathogenic detection of viral encephalitis.It is also a useful tool for the high-volume screening of clinical samples.

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.

Primary bile acids were reported to augment secretion of chemokine (C‒X‒C motif) ligand 16 (CXCL16) from liver sinusoidal endothelial cells (LSECs) and trigger natural killer T (NKT) cell-based immunotherapy for liver cancer. However, abundant expression of receptors for primary bile acids across the gastrointestinal tract overwhelms the possibility of using agonists against these receptors for liver cancer control. Taking advantage of the intrinsic property of LSECs in capturing circulating nanoparticles in the circulation, we proposed a strategy using nanoemulsion-loaded obeticholic acid (OCA), a clinically approved selective farnesoid X receptor (FXR) agonist, for precisely manipulating LSECs for triggering NKT cell-mediated liver cancer immunotherapy. The OCA-nanoemulsion (OCA-NE) was prepared

OBJECTIVETo establish questionnaire scaling and reliability and examine the clinical and psychometric validity of the quality of life assessment based on Traditional Chinese Medicine for advanced gastric cancer (QLASTCM-Ga).

METHODSThe QLASTCM-Ga was developed based on programmed decision procedures with multiple nominal and focus group discussions, in-depth interview, pretesting and quantitative statistical procedures. The questionnaire was administered to 240 patients diagnosed with advanced gastric cancer before and after treatment. Structured group methods were employed to establish a general and a specifific module respectively. The psychometric properties of the scale were evaluated with respect to validity, reliability and responsiveness.

RESULTSThe three identified scales of the QLASTCM-Ga and the total score demonstrated good psychometric properties. Test-retest reliability of the total scale and all domains ranged from 0.90 to 0.94, and internal consistency ranged from 0.86 to 0.93. Correlation and factor analysis demonstrated good construct validity. Signifificant difference in the subscales and the total score were found among groups differing in traditional Chinese medicine syndrome, supporting the clinical sensitivity of the QLASTCM-Ga. Statistically signifificant changes were found for each scale and the total score. Responsiveness was also good.

CONCLUSIONSThe QLASTCM-Ga demonstrates good psychometric and clinical validity to assess quality of life in patients with advanced gastric cancer undergoing traditional Chinese medicine therapy. This study is an important fifirst step for future research in this area.

This study examined the prevalence of primary open-angle glaucoma (POAG) among residents aged ≥50 years living in Yongchuan district of Chongqing. Stratified cluster sampling was employed in random selection to estimate the prevalence of glaucoma from April to June, 2005. Twenty-nine villages or neighborhood communities were randomly selected in urban area (Zhongshan Road), suburban area (Shanjiao Town) and exurban area (Zhutuo Town) of this district. All the respondents underwent detailed ophthalmic examinations. The examinations included questionnaire investigation, visual acuity test, naked-eye examination, measurement of peripheral anterior chamber depth (Van Herrick's technique), detection of intraocluar pressure (IOP) with a Perkins hand-held applanation tonometer (HA-2) and examination of the optic disc by using a 78 diopters (D) lens (including the cup-disc ratio, cup/disc ratio asymmetries, horizontal and vertical diameter, notching and optic disc hemorrhages). A total of 5938 residents were actually examined, and the response rate was 85.19%. The crude prevalence of POAG was 0.86% (n=51/5938, 95% CI 0.64%-1.11%). There were 24 males and 27 females in the glaucoma group. The glaucoma prevalence was not significant different in case number between the male and female subjects (P=0.4900). Furthermore, no association between age or schooling and POAG was noted (P=0.8030, 0.0734). Out of 51 subjects with POAG, unilateral glaucoma-related blindness occurred in 38 subjects (74.5%) and bilateral glaucoma-related blindness was found in 7 subjects (13.7%). This study exhibited that the prevalence of POAG was 0.86% among residents aged ≥50 years living in Yongchuan District of Chongqing. The vision loss caused by POAG in this population was obviously higher than that previously reported in other studies. Glaucoma management, detection of affected persons and handling of the burden of glaucoma should be the priorities of the agenda of local health authorities of Western China.

Objective To investigate the effects of Shenfu injection on blood pressure and heart rate of patients receiving carotid artery stenting.Methods One hundred and twenty patients were randomly divided into the treatment group and the control group , sixty cases in each group.The control group received conventional medication under custodial care , and the treatment group was given Shenfu ( 1 mL · kg -1 ) 10 minutes before surgery.Mean arterial pressure(MAP), heart rate (HR), oxygen satu-ration (SpO2), as well as the frequency of intra -operative hypotension, and the applications of ephedrine and atropine were recorded respectively at the beginning of surgery , the 30 th minute during surgery , the end of surgery and 24 hours after the surgery.Results The operations were all successful , and no adverse reactions occurred.MAP in treatment group at the 30th minute during surgery was higher than in the control group , while it was lower than of the control group at the end of surgery ( P<0.01).HR in the treatment group (68.25 ±7.35) times· min-1 was lower than that of the control group (73.28 ±10.43)times· min-1 at the end of surgery (P<0.05 ).Conclusion Shenfu injection helps stabilize blood pressure and heart rate of patients receiving carotid artery stenting through the two-way adjustment , and it could reduce the occurrence of cerebrovascu-lar accident during the per -operative period.

BACKGROUNDPatients with schizophrenia have prominent abnormality in information processing that can be observed by measures of prepulse inhibition (PPI) of acoustic startle reflex and PPI deficits have been considered as a candidate endophenotypic marker of schizophrenia. However, there has been little information on PPI and related measures in Chinese patients with schizophrenia. The research was to explore the deficits of acoustic startle reflex that might exist in Chinese patients with schizophrenia.

METHODSStartle response to acoustic stimuli, habituation, and PPI were examined in 31 Chinese patients with first-episode, medication-naïve schizophrenia and 30 age- and sex-matched healthy Chinese controls. At the same day of startle testing, psychopathological symptoms of the patients were assessed with the Positive and Negative Syndrome Scale (PANSS).

RESULTSCompared with healthy controls, patients exhibited the significant reduction in startle response and PPI deficits at 60 milliseconds (ms) intervals (PPI60, P < 0.05) but not at 30 or 120 ms intervals. Furthermore, there was a relatively strong correlation between PPI60 (P < 0.05) and scores of positive scale of PANSS in patients with schizophrenia.

CONCLUSIONOur findings confirmed impaired PPI in Chinese patients with schizophrenia and suggested that a relationship between sensorimotor gating deficits and clinical symptoms of patients with schizophrenia might exist.
