Background:
Due to the unavailability of an effective vaccine or antiviral drug against the African swine fever virus (ASFV), rapid diagnosis methods are needed to prevent highly contagious African swine fever.
Objectives:
The objective of this study was to establish the ladder-shape melting temperature isothermal amplification (LMTIA) assay for the detection of ASFV.
Methods:
LMTIA primers were designed with the p72 gene of ASFV as the target, and plasmid pUC57 was used to clone the gene. The LMTIA reaction system was optimized with the plasmid as the positive control, and the performance of the LMTIA assay was compared with that of the commercial real-time polymerase chain reaction (PCR) kit in terms of sensitivity and detection rate using 200 serum samples.
Results:
Our results showed that the LMTIA assay could detect the 10 4 dilution of DNA extracted from the positive reference serum sample, which was the same as that of the commercial real-time PCR kit. The coincidence rate between the two assays was 100%.
Conclusions
The LMTIA assay had high sensitivity, good detection, and simple operation. Thus, it is suitable for facilitating preliminary and cost-effective surveillance for the prevention and control of ASFV.

Objective To investigate the effect of ulinastatin combined pantoprazole on inflammatory factors and gastrointestinal tract in patients undergoing cardiopulmonary bypass ( CBP) cardiac surgery. Methods A total of 200 patients who suffered rheumatic heart disease were scheduled for valve replacement surgery with CPB, were randomly divided into four groups:control group (CON),ulinastatin (UTI),pantoprazole groups (PTZ) and ulinastatin+pantoprazole groups(UTI+PTZ),50 cases in each group.Before CBP,group UTI was given ulinastatin 10 000 U·kg-1,group PTZ was given pantoprazole 40 mg,group UTI+PTZ was given ulinastatin 10 000 U·kg-1and pantoprazole 40 mg,group CON was given 0.9% sodium chloride soution.The gastric mucosa pHi and blood samples would be collected in all four groups at the preoperative (t1),CPB 30 min (t2),after CBP (t3),6 h after surgery (t4),24 h (t5) five time points.The IL-6 and TNF-α would be detected by enzyme linked immunosorbent (ELISA) method,and abdominal distension,abdominal pain,hematemesis,black and defecate occult blood test positive for digestive tract related complications would be collected after the surgery 1,2 days. Results The concentration of TNF-α and IL-6 at t2,t3, t4,t5were higher than those at t1in all four groups(P<0.05).Compared with CON group,the concentration of TNF-α and IL-6 at t2, t3,t4,t5in UTI,PTZ and UTI+PTZ group were significantly decreased (P<0.05).The concentration of TNF-α and IL-6 in UTI and UTI+PTZ group were better than in PTZ group.The pHi at t2,t3,t4was lower than that at t1in four groups(P<0.05),and pHi at t5 was obviously lower than that at t1in group CON (P<0.05).The pHi at t2,t3,t4in UTI,PTZ and UTI+PTZ group was higher than that in CON group ( P<0. 05), and pHi in UTI+PTZ group was better than that in UTI and PTZ group. The postoperative gastrointestinal complications in CON group were higher than those in UTI,PTZ and UTI+PTZ group (P<0.05). Conclusion Ulinastatin combined with pantoprazole for patients undergoing CPB heart surgery,can significantly reduce the release of TNF-α and IL-6、increase gastric pHi and reduce the incidence of gastrointestinal complications.

Objective To get an understanding of the patient experience in public hospitals nationwide, and to evaluate the implementation of the Action Plan to Improve Health Care. Methods Supported by the mobile technology, from September 6, 2017 to December 15, 2018, the authors conducted an online survey that measured the satisfaction of both inpatients and outpatients at secondary and tertiary hospitals across the country. 15 questions from six dimensions including registration experience, patient-doctor communication, nurse-patient communication, the healthcare signage system, responsiveness of care providers and privacy protection were prepared for outpatients, while 20 questions from nine aspects such as nurse-patient communication, patient-doctor communication, pain management, medication communication, admission and discharge information, responsiveness of care-givers, food service, friendliness to patient family, and the healthcare signage system were directed at inpatients. Descriptive statistical analysis was used to describe the basic features of the data. Results 9.18 million valid responses from outpatients and another 5.38 million from inpatients were obtained. The overall satisfaction rate with outpatient services had reached a score of 90.45 points where nurse-patient communication stands out as the top-rated dimension and privacy protection gets the lowest rating. On the other hand, the inpatient satisfaction stands at a score of 93.01 with friendliness to patient family receiving the top score and patient-doctor communication the lowest. Conclusions Despite the positive feedback Chinese patients give on the outpatient care they receive, we should make efforts to improve the outpatient care environment, the wayfinding system, privacy protection, and responsiveness of care-givers.

Objective To evaluate the clinical efficacy and safety of continuous renal replacement therapy (CRRT) in patients with severe acute pancreatitis (SAP) receiving percutaneous drainage (PCD). Methods Clinical data of SAP patients receiving PCD admitted to department of hepatobiliary surgery of the First Affiliated Hospital of Xi'an Jiaotong University from November 11th 2015 to May 13th 2018 were retrospectively analyzed. The patients were divided into CRRT group and control group according to whether or not receiving CRRT. Demographic data, relevant variables before and after PCD, complication and outcome were all compared. Results A total of 75 patients were included in the study, 30 were treated with application of CRRT and 45 without CRRT. ① There was no significant difference in gender, age, body mass index (BMI), medical history (smoking, drinking), complications (cardiovascular disease, chronic lung disease, diabetes, chronic renal insufficiency), etiology (gallstone, alcohol abuse, hyperlipidemia and others), or white blood cell count (WBC), C-reactive protein (CRP), serum procalcitonin (PCT), fluid resuscitation, mechanical ventilation, vasoactive agent or intra-abdominal pressure within 48 hours after admission between the two groups. However, acute physiology and chronic health evaluationⅡ(APACHEⅡ) score within 48 hours after admission of CRRT group was significantly higher than that of control group (18.3±4.5 vs. 12.8±6.2, P < 0.05). ② There was no significant difference in WBC, PCT, APACHEⅡ score or computed tomography severity index (CTSI) before PCD between the two groups. There was no significant difference in the position or times of PCD procedure between the two groups, but the time interval of PCD in the CRRT group was significantly longer than that in the control group (days: 19.4±5.4 vs. 12.8±2.2, P < 0.05). Meanwhile, there was no significant difference in drainage of fluid properties, incidence of abdominal bleeding, infection, gastrointestinal fistula, endoscopic removal of necrotic tissue, laparotomy for removal of necrotic tissue or the time from PCD to endoscopy or laparotomy between two groups. However, the length of intensive care unit (ICU) stay and the length of hospital stay in the CRRT group were significantly longer than those in the control group (days: 23.2±8.5 vs. 15.3±12.1, 51.2±21.2 vs. 31.2±14.0, both P < 0.01). ③ Kaplan-Meier survival analysis showed that there was no significant differences in 1-year or 3-year cumulative survival rates between the two groups (χ21 = 0.097, P1 = 0.755; χ22 = 0.013, P2 = 0.908). Conclusions CRRT is safe and feasible in the treatment of SAP patients receiving PCD procedure. It does not increase the risk of bleeding and may delay the time interval of PCD intervention. However, it may prolong the length of ICU stay and the length of hospital stay. It should be worthy of much attention for clinicians.

Objective To evaluate the efficacy and safety of oXiris hemofilter for septic shock patients. Methods Clinical data of septic shock patients receiving continuous renal replacement therapy (CRRT) with oXiris hemofilter in department of surgical intensive care unit (SICU) of the First Affiliated Hospital of Xi'an Jiaotong University from March 1st, 2018 to July 20th, 2019 were retrospectively analyzed. The heart rate (HR), mean arterial pressure (MAP), oxygenation index (PaO2/FiO2), lactate (Lac), platelet count (PLT), serum procalcitonin (PCT), interleukin-6 (IL-6) and C-reactive protein (CRP), noradrenaline (NE) dosage, acute physiology and chronic health evaluation Ⅱ(APACHEⅡ) and sequential organ failure score (SOFA) were compared before and after oXiris treatment and the prognosis were also analyzed. Results Six patients with septic shock were included [5 males, the average age was (56.3±11.8) years old]. A total of 13 oXiris hemofilter sets were performed during treatment. Compared with before treatment, the HR, IL-6 and CRP levels were significantly decreased after treatment [HR (bpm): 93.8±9.7 vs. 133.5± 18.3, IL-6 (ng/L): 509.2±169.6 vs. 3739.8±618.2, CRP (mg/L): 169.1±148.3 vs. 277.8±68.7, all P < 0.05], MAP, PaO2/FiO2 and PLT were significantly increased [MAP (mmHg, 1 mmHg = 0.133 kPa): 73.3±2.2 vs. 63.3±1.6, PaO2/FiO2 (mmHg): 166.8±40.4 vs. 95.1±56.2, PLT (×109/L): 73.3±27.5 vs. 41.2±21.4, all P < 0.05]; meanwhile, NE dosage, APACHEⅡ and SOFA scores were significantly decreased [NE (μg·kg-1·min-1): 0.4±0.3 vs. 1.2±0.7, APACHEⅡ:18.8±6.9 vs. 30.0±7.3, SOFA: 11.7±4.2 vs. 17.3±2.1, all P < 0.05]. Although Lac and PCT decreased after treatment, there was no significant difference [Lac (mmol/L): 3.5±2.1 vs. 6.1±3.2, PCT (μg/L): 37.7±48.3 vs. 85.1±32.8, both P > 0.05]. At the end, 3 of the 6 patients survived and the others were discharged again medical advice. The length of SICU stay was 3 to 23 days, with an average of (13.0±8.5) days. No adverse events occurred during the treatment. Conclusion oXiris hemofilter can effectively remove inflammatory mediators in circulation, significantly improve hemodynamic status and severity, and may be considered as a safe and reliable treatment modality for septic shock patients.

Objective To investigate the effect of diurnal temperature difference on hospitalization volume of patients with cardiovascular and cerebrovascular diseases in Urumqi City. Methods The daily hospitalization data for cardiovascular and cerebrovascular diseases in Urumqi City from 2019-2021, and meteorological and pollutant data for the same period were collected. The relationship between diurnal temperature range and hospitalizations for cardiovascular and cerebrovascular diseases was analyzed using a distribution lag non-linear model (DLNM), controlling for the long-term trends, the day-of-week effects and other factors. Results The greater the diurnal temperature range, the longer the lag time, and the higher the risk of hospitalization for cardiovascular and cerebrovascular diseases. The lag effect increased significantly when the maximum diurnal temperature range reached 21.0°C. The risk effect appeared on the day of exposure and lasted until day 20, with a maximum RR of 1.266 (95% CI: 1.129-1.421) at a lag of 13 days. At very high diurnal temperature range, the risk of hospitalization for cardiovascular and cerebrovascular diseases was higher in the cold season than that in the warm season. Results after stratified analysis by sex and age showed that men and people aged ≥65 years were more susceptible to diurnal temperature range. Conclusion Extremely high diurnal temperature range is a potential trigger for hospitalization for cardiovascular and cerebrovascular diseases in Urumqi. Men and people aged ≥65 years are more vulnerable to the impact of diurnal temperature range. In the cold season, more attention should be paid to protecting vulnerable people from the impact of the extremely high diurnal temperature difference.

Background Maternal atmospheric pollution during pregnancy may alter fetal intrauterine development programming, thereby increasing the risk of childhood obesity in the future. Objective To investigate the effects of atmospheric pollution exposure during pregnancy on the incidence of childhood obesity in offspring. Methods English databases (PubMed, Web of Science, and Medline) and Chinese databases (Wanfang Data Knowledge Service Platform, China National Knowledge Infrastructure, and VIP Information Chinese Journal Service Platform) were searched for literature reporting exposure to atmospheric pollution during pregnancy and childhood obesity published from 1 January 2000 to 31 August 2023. The quality of the included literature was evaluated using the quality assessment tools for observational cohort and cross-sectional studies recommended by the US National Institutes of Health. Results Twenty-four studies meeting the inclusion criteria were identified and the associated atmospheric pollutants included particulate matter, ozone, nitrogen oxide, carbon oxide, and sulfur oxide. In comparison to the non-exposed group, prenatal exposure to various common atmospheric pollutants were significantly associated with an elevated risk of childhood obesity in offspring. Conclusion Maternal exposure to atmospheric pollution during pregnancy is associated with an elevated risk of childhood obesity in subsequent years. Future studies should pay more attention to the effects of atmospheric pollution on the distribution of children's body fat and metabolic development, and further identify potential mechanisms of atmospheric pollutant exposure leading to childhood obesity.
