Objective:To observe any effect of supplementing basic swallowing training with balloon catheter dilation on the swallowing function of tracheostomy patients with pontine hemorrhage.Methods:A total of 40 pontine hemorrhage patients with tracheostomy and swallowing disorders were divided randomly into an observation group and a control group, each of 20. Both groups were given nutritional neurodrugs and basic swallowing training, but the observation group also received 25 minutes of balloon catheter dilation, five times a week for 6 weeks. Before and after the 6 weeks of treatment one swallowing therapist evaluated the feeding ability and leakage-aspiration status of each subject assigning functional oral intake (FOIS) ratings and Rosenbek Leakage/Aspiration Rating Scale (PAS) ratings double-blinded. The Watian water swallowing test was also applied.Results:After the treatment the average FOIS and PAS scores of both groups had improved significantly, with those of the observation group then significantly better than among the control group on average. The total treatment effectiveness rate was 70% in the observation group, significantly better than the 30% in the control group.Conclusion:Supplementing swallowing training with balloon catheter dilation can better improve the swallowing of patients recovering from a tracheotomy after pontine hemorrhage.

Objective To investigate the spatiotemporal distribution characteristics and potential influencing factors of newly diagnosed echinococcosis cases in Qinghai Province from 2016 to 2022, so as to provide insights into the formulation of the echinococcosis control strategy in Qinghai Province. Methods The number of individuals screened for echinococcosis, number of newly diagnosed echinococcosis cases, number of registered dogs and number of stray dogs were captured from the annual reports of echinococcosis control program in Qinghai Province from 2016 to 2022, and the detection of newly diagnosed echinococcosis cases was calculated. The number of populations, precipitation, temperature, wind speed, sunshine hours, average altitude, number of year-end cattle stock, number of year-end sheep stock, gross domestic product (GDP) per capita, and number of village health centers in each county (district) of Qinghai Province were captured from the Qinghai Provincial Statistical Yearbook, and county-level electronic maps in Qinghai Province were downloaded from the National Platform for Common Geospatial Information Services. The software ArcGIS 10.8 was used to map the distribution of newly diagnosed echinococcosis cases in Qinghai Province, and the spatial autocorrelation analysis of newly diagnosed echinococcosis cases was performed. In addition, the spacetime scan analyses of number of individuals screened for echinococcosis, number of newly diagnosed echinococcosis cases and geographical coordinates in Qinghai Province were performed with the software SaTScan 10.1.2, and the spatial stratified heterogeneity of the detection of newly diagnosed echinococcosis cases was investigated with the software GeoDetector. Results A total of 6 569 426 residents were screened for echinococcosis in Qinghai Province from 2016 to 2022, and 5 924 newly diagnosed echinococcosis cases were found. The detection of newly diagnosed echinococcosis cases appeared a tendency towards a decline over years from 2016 to 2022 (χ² = 11.107, P < 0.01), with the highest detection in Guoluo Tibetan Autonomous Prefecture in 2017 (82.12/10⁵). There were spatial clusters in the detection of newly diagnosed echinococcosis cases in Qinghai Province from 2016 to 2018 (Moran’s I = 0.34 to 0.65, all Z values > 1.96, all P values < 0.05), and the distribution of newly diagnosed echinococcosis cases appeared random distribution from 2019 to 2022 (Moran’s I = −0.09 to 0.04, all Z values < 1.96, all P values > 0.05). Local spatial autocorrelation analysis showed high-high clusters and low-low clusters in the detection of new diagnosed echinococcosis cases in Qinghai Province from 2016 to 2022, and space-time scan analysis showed that the first most likely cluster areas of newly diagnosed echinococcosis cases in Qinghai Province from 2016 to 2022 were mainly distributed in Yushu Tibetan Autonomous Prefecture and Guoluo Tibetan Autonomous Prefecture. GeoDetector-based analysis of the driving factors for the spatial stratified heterogeneity of detection of newly diagnosed echinococcosis cases in Qinghai Province showed that average altitude, number of village health centers, number of cattle and sheep stock, GDP per capita, annual average sunshine hours, and annual average temperature had a strong explanatory power for the spatial distribution of newly diagnosed echinococcosis cases, with q values of 0.630, 0.610, 0.600, 0.590, 0.588, 0.537 and 0.526, respectively. Conclusions The detection of newly diagnosed echinococcosis cases appeared a tendency towards a decline in Qinghai Province over years from 2016 to 2022, showing spatial clustering. Targeted control measures are required in cluster areas of newly diagnosed echinococcosis cases for further control of the disease.

Purpose: Patients with advanced biliary tract cancer (BTC) have a poor survival. We aim to evaluate the efficacy and safety of nab-paclitaxel plus gemcitabine and cisplatin regimen in Chinese advanced BTC patients. Materials and Methods: Eligible patients with locally advanced or metastatic BTC administrated intravenous 100 mg/m2 nab-paclitaxel, 800 mg/m2 gemcitabine, and 25 mg/m2 cisplatin every 3 weeks. The primary endpoint was progression-free survival (PFS). The secondary endpoints included overall survival (OS) and adverse events, while exploratory endpoint was the association of biomarkers with efficacy. Results: After the median follow-up of 25.0 months, the median PFS and OS of 34 enrolled patients were 7.1 months (95% confidence interval [CI], 5.4 to 13.7) and 16.4 months (95% CI, 10.9 to 23.6), respectively. The most common treatment-related adverse events at ≥ 3 grade were neutropenia (26.5%) and leukopenia (26.5%). Survival analyses demonstrated that carcinoembryonic antigen (CEA) levels could monitor patients’ survival outcomes. A significant increase in the number of infiltrating CD4+ cells (p=0.008) and a decrease in programmed death-1–positive (PD-1+) cells (p=0.032) were observed in the response patients. Conclusion In advanced BTC patients, nab-paclitaxel plus gemcitabine and cisplatin regimen showed therapeutic potential. Potential prognostic factors of CEA levels, number of CD4+ cells and PD-1+ cells may help us maximize the efficacy benefit.

Objective: To investigate the effects of a ketogenic diet (KD) alone and in combination with resistance training (KD+RT) on body composition and glucolipid metabolism of obese and female college students, and to provide a theoretical basis for the application of KD+RT in obese patients. Methods: Totally 45 obese and female college students in Wuyi University were recruited and randomly divided into KD group ( n =23) and KD+RT group ( n =22) in September 2021. After received training for 4 weeks, the changes of body composition and glucose and lipid metabolism of obese and female college students were compared before and after intervention. Results: Both a 4 week KD and KD+RT led to decreases in weight, BMI, body fat mass, body fat percentage, waist to hip ratio, visceral fat area of obese female college students ( t =16.19, 16.21, 12.42, 7.99, 2.10, 6.37; 18.82, 18.02, 17.80, 10.72, 3.41, 7.59, P <0.01). The change of muscle mass was decreased in KD group( t=4.12, P <0.01), but there was no statistically significant difference in KD+RT group( P >0.05). Both a 4 week KD and KD+RT significantly reduced the levels of the fasting blood glucose, fasting insulin, glycosylated hemoglobin and triglyceride (TG) of obese female college students ( t =10.15, 8.94 , 6.94, 7.63; 9.23, 12.75, 9.85, 9.09, P <0.01), and increased the high density lipoprotein (HDL) level( t =-7.36, -5.22, P <0.01). However, only KD+RT group had a significant decrease in the level of LDL ( t =5.27, P <0.01), and there was no significant change in the level of TC both groups ( P >0.05). After the intervention, there was no statistically significant difference between the KD+RT group compared to the KD group ( P >0.05), except for a significant decrease in triacylglycerol ( t =2.51, P < 0.05 ). Conclusion Both a short term KD and KD+RT show beneficial changes in body composition and glucolipid metabolism in obese female college students. However, the KD+RT is superior to a KD in maintaining muscle mass and reducing the effects of lipid metabolism.

The hemodynamics of children with congenital heart disease (CHD) often changes during the perioperative period. Unfortunately, the evaluation of cardiac function in children with CHD is mainly focused on the left ventricle. With the further understanding of cardiac hemodynamics, the monitoring of RV function has gradually become an important part of cardiac intensive care department. We totally searched five databases including Pubmed, Embase, Cochrane, Wanfang Med, as well as China National Knowledge Infrastructure (CNKI) and reviewed the clinical research progress of the application of TAPSE in the evaluation of RV systolic function in children with CHD to provide a theoretical basic for the monitoring of RV function before and after operation in children with CHD.

Objective:To investigate the short-term clinical efficacy of SuperCAP artificial femoral head replacement and proximal femoral anti rotation intramedullary nail (PFNA) internal fixation in the treatment of intertrochanteric fractures in patients with osteoporosis.Methods:A retrospective analysis was conducted on the clinical data of patients with osteoporosis and intertrochanteric fractures admitted to the Orthopedic Department of Changsha First Hospital from January 2017 to January 2020. The patients underwent SuperCAP artificial femoral head replacement or PFNA internal fixation surgery. According to the inclusion and exclusion criteria, a total of 32 cases were included in the SuperCAP group and 46 cases in the PFNA group. We compared the age, gender, fracture classification, bone density, American Society of Anesthesiologists (ASA) score, surgical time, postoperative weight bearing time, intraoperative bleeding volume, incidence of perioperative complications, and Oxford Hip Score (OHS) between two groups of patients.Results:There was no statistically significant difference in age, gender, fracture classification, bone density, ASA score, surgical time, intraoperative bleeding, and the OHS at 6 months and 1 year after surgery between the two groups of patients (all P>0.05). The SuperCAP group had better postoperative weight bearing time, incidence of perioperative complications, and OHS at 1 week, 1 month, and 3 months compared to the PFNA group (all P<0.05). Conclusions:SuperCAP minimally invasive approach for the treatment of osteoporotic femoral intertrochanteric fractures can achieve the same effect as PFNA internal fixation, and the short-term effect of SuperCAP artificial femoral head replacement is better than PFNA internal fixation.

ObjectiveTo investigate effect of conducting training of autism spectrum disorder （ASD） early screening skill on improving the ability to early identify ASD of medical staffs in primary care hospitals. MethodsIn September 2021， the training of ASD early screening skills was carried out for medical staffs from 20 primary care hospitals in Chengdu. After training， the training effect was evaluated. The numbers of referrals from primary care hospitals to superior hospitals， confirmed ASD as well as their average diagnostic age of children with ASD before and after training were used as evaluation indicators. ResultsAfter training， the number of children with suspected ASD referred by primary care hospitals was more than that before training ［（16.65±11.60） vs. （3.40±2.23）， t=5.431， P<0.01］， the number of children diagnosed with ASD was more than that before training［（6.85±4.93） vs. （2.45±1.67）， t=4.171， P<0.01］， and the differences were statistically significant. As for the diagnosed age of ASD children， after training， the average age was lower than that before training ［（34.95±11.67） vs. （42.2±14.64）， t=-2.553， P=0.019］. ConclusionTraining of ASD early screening skills for medical staffs in primary care hospitals may help to improve their ability to early screening ASD children.

Objective:To classify the symptom characteristics of young and middle-aged peritoneal dialysis patients and to explore the differences of demographic functional status and social function of patients with different symptom categories.Methods:A total of 179 peritoneal dialysis patients from 3 peritoneal dialysis centers in Shanghai were investigated from December 2019 to August 2020 by General Information Questionnaire, Peritoneal Dialysis Symptom Distress Scale. Latent class analysis was used to classify young and middle-aged peritoneal dialysis patients according to symptom characteristics. Multiple Logistic regression was used to explore the differences of demographic and disease characteristics of different categories of patients.Results:Peritoneal dialysis patients could be divided into three potential categories according to symptom characteristics ( P<0.05). According to the conditional probability of each category, they were named "low symptom group" (111 cases,62.0%), "high psychological-moderate physical symptom group" (22 cases, 12.3%), "high symptom group" (46 cases,25.7%). There were differences in working status ( OR=0.029, P<0.01), education level ( OR=152.799, P<0.01), duration ( OR=81.307, P<0.05), diabetic nephropathy ( OR=80.619, P<0.01) and CCI score ( OR=91.188, P<0.01) distribution among different potential categories of young and middle-aged peritoneal dialysis patients. Conclusions:There are three types of potential symptoms in young and middle-aged patients undergoing peritoneal dialysis. In clinical practice, medical staff should focus on the psychological status of young and middle-aged patients with low educational background and early stage of dialysis, and encourage them to return to work; at the same time, they should regularly evaluate the symptom burden of patients with diabetic nephropathy and high complication index peritoneal dialysis patients, in order to provide targeted intervention measures to prevent the progression of the disease.

OBJECTIVE: To construct a HIV-1 gp120 transgenic mice (gp120 Tg) with vimentin (VIM) gene knockout. METHODS: Female HIV-1 gp120 Tg mice were mated to VIM heterozygote mice (F0). All the offspring mice were derived from these original founders so that both genotypes had the same mixed genetic background. The F1 mice were bred to generate of VIM, VIM, VIM/gp120 Tg and VIM/gp120 Tg mice. PCR was performed for genotyping of the mice, and the expressions of VIM and gp120 in the brain tissues were examined using immunoblotting. RESULTS: The results of PCR showed the presence of the target bands in VIM, VIM, VIM/gp120 Tg and VIM/gp120 Tg mice. In VIM/gp120 Tg mice, gp120 expression was detected throughout the brain regions while no VIM expression was detected. CONCLUSIONS We generated gp120 transgenic mouse models with VIM gene knockout, which facilitate the exploration of the role of VIM in gp120-induced neurotoxicity.
