Objective:To understand the incidence of diabetes and influencing factors, the trend of FPG change and risk for mortality in HIV-infected individuals after antiretroviral therapy (ART) in Dehong Dai and Jingpo Autonomous Prefecture (Dehong).Methods:The HIV/AIDS treatment database was collected from China Information System for Disease Control and Prevention. This retrospective cohort study was conducted in HIV-infected individuals with access to ART in Dehong during 2004-2020.The Cox proportional hazard regression model was used to analyze the incidence density of diabetes, the influencing factors and risk for mortality in HIV-infected individuals with access to ART, mixed linear effects model was used to analyze the trend of FPG change and predict FPG in those with different glucose metabolic status at baseline survey. Statistical analysis was performed using software SAS 9.4.Results:A total of 8 763 HIV-infected individuals were included, in whom 8 432 (96.2%) had no diabetes, 331 had diabetes. The incidence density of diabetes was 2.31/1 000 person years. Multivariate Cox proportional hazard regression analysis revealed that 30- 59 years old, BMI ≥24.0 kg/m 2, Efavirenz (EFV) based initial treatment regimen and impaired fasting glucose (IFG) at baseline survey were significantly and positively associated with incidence of diabetes. Mixed effect model revealed that FPG was positively correlated with the duration of ART, age and baseline FPG. Suffering from diabetes was a risk factor for mortality in HIV-infected individuals both at baseline survey and during follow-up. Conclusions:The risk for diabetes increased in HIV-infected individuals who were 30-59 years old, baseline BMI ≥24.0 kg/m 2, received EFV based initial treatment, and IFG in HIV-infected individuals after antiretroviral therapy in Dehong, 2004-2020. It is important to pay close attention to their blood glucose, and patients with high blood glucose should receive treatment as early as possible.

Objective:To explore the curative efficacy of tandem autologous stem cell transplantation (ASCT) for high-risk multiple myeloma (HRMM).Methods:From January 2017 to December 2021, retrospective analysis was conducted for 240 initially diagnosed HRMM patients. According to different treatment protocols after induction chemotherapy, they were further assigned into three groups of tandem ASCT (n= 20) ,single ASCT (n=80) and non-transplantation (n= 140). Rates of deep response (very good partial response and above) before and after transplantation and differences in 2-year progression-free survival (PFS) and overall survival (OS) were compared among three groups. The prognostic factors of HRMM were examined by univariate and multivariate analyses.Results:In single ASCT group, the rates of deep responses were 67.50% (54/80) after induction chemotherapy and 80.00 % (64/80) post-ASCT ( P=0.072). There were no significant statistical differences. In tandem ASCT group, the rates of deep response were 65.00% (13/20) after induction chemotherapy and 95.00 % (19/20) post-ASCT ( P=0.018). There were significant statistical differences. The 2-year PFS of tandem ASCT, single ASCT and non-transplantation groups were (75.00±2.90) %, (71.25±3.00) % and (61.43±3.10) % respectively. No statistically significant difference existed in 2-year PFS rates between single ASCT and non-transplantation groups, as well as between tandem ASCT and single ASCT groups ( P=0.365 and P=0.052). Significant difference existed in 2-year PFS between tandem ASCT and non-transplantation groups ( P<0.032). Two-year OS rates of tandem ASCT, single ASCT and non-transplantation groups were (90.00±3.50) %, (78.75±2.70) % and (62.86±2.50) % respectively. No statistically significant difference existed in 2-year OS rate between single ASCT and non-transplantation groups, as well as between tandem ASCT and single ASCT groups ( P=0.071 and P=0.057). Significant difference existed in 2-year OS between tandem ASCT and non-transplantation groups ( P=0.003). Univariate and multivariate analyses indicated that the independent prognostic factors affecting PFS were multi-hit, stages RISS-Ⅲ and failure to achieve very good partial response (VGPR) after four cycles of induction therapy and non-tandem ASCT. The independent prognostic factors affecting OS were multi-hit, stages RISS-Ⅲ and non-tandem ASCT. Conclusion:Tandem ASCT not only significantly improves the depth of remission but also further enhances 2-year PFS/OS of HRMM patients. It is a recommended treatment for HRMM.

Objective:To compare the efficacy of endoscopic submucosal dissection (ESD) and modified-endoscopic mucosal resection (M-EMR) for G1 rectal neuroendocrine tumors (RNETs) .Methods:Data of 121 patients with pathologically confirmed G1 RNETs treated with ESD ( n=105) or M-EMR ( n=16) in Nanjing Drum Tower Hospital from January 2017 to September 2020 were retrospectively analyzed. The complete resection rate, complication incidence, hospital stay, treatment cost and other indicators of the two groups were compared by using inverse probability of treatment weighting (IPTW). Results:There were significant differences in tumor number ( χ2=8.76, P=0.003), tumor invasion depth ( χ2=6.96, P=0.008), utilization of metal clips [82.9% (87/105) VS 93.8% (15/16), χ2=8.78, P=0.003], number of metal clips ( χ2=8.41, P=0.016), hemostasis using hot clamp [78.1% (82/105) VS 18.7% (3/16), χ2=20.64, P<0.001], traction procedure [2.9% (3/105) VS 18.7% (3/16), χ2=4.45, P=0.035] and treatment cost (17 568.6 ± 8 911.0 yuan VS 8 120.8±1 528.2 yuan, t=3.65, P<0.001) between the ESD group and the M-EMR group. After verifying the stability of the results using IPTW sensitivity analysis, there was still significant difference in the treatment cost ( t=2.07, P<0.001). Conclusion:Both ESD and M-EMR demonstrate comparable efficacy in treating G1 RNETs; however, M-EMR exhibites lower treatment costs.

Objective:To evaluate the barrier-free level of village clinics of a city in the aging era, for references in improving the barrier-free medical environment for the elderlies.Methods:The village dectors of 156 village clinics in 12 counties of a city were selected as the objects of a questionnaire survey from Dec.2020 to Jan.2021, with 6 evaluation indexes established, each set with 1-10 points. This questionnaires was used to survey the barrier-free construction levels of village clinics. The data were statistically analyzed by rank sum ratio and quadrant graph model.Results:The barrier-free buildings of such clinics scored 32.86 points in average. Among the six indexes, the barrier-free access and doors(7.21 points) scored the highest, and the barrier-free parking space(4.71points) and toilets(3.28 points) scored the lowest. All the counties of the city fell into four categories, including 2 counties with high degree of aging-high level of accessibility, 4 counties with low degree of aging-high level of accessibility, 4 counties with low degree of aging-low level of accessibility, and 2 counties with high degree of aging-low level of accessibility, according to the quadrant graph model built based on the aging degrees and the barrier-free levels of village clinics.Conclusions:The barrier-free level of the village clinics in a city needs to be further improved, and the barrier-free transformation of parking space and toilets should also be strengthened in the future. The government should take different measures in view of conditions of each county to improve the accessibility of village clinics and facilitate the health care-seeking of elderlies.

Objective:To explore the application of digital acoustic analysis in assessing the risk of aspiration among persons with dysphagia using the Praat speech analysis software.Methods:The swallowing of 46 stroke survivors with dysphagia was studied using video fluoroscopy. Each patient was required to pronounce " yi/i/" 3 times before and after taking each mouthful of food, and their voice samples were collected. The subjects were divided into a non-aspiration group of 16 and an aspiration group of 30 based on their penetration-aspiration scale scores. Fundamental frequency, relative average perturbation (RAP), jitter, shimmer, amplitude perturbation quotient and harmonic-to-noise ratio were compared between the two groups before and after taking food.Results:For the non-aspiration group, there was no significant difference in the acoustic data before and after eating. For the aspiration group there were significant differences in fundamental frequency, relative average perturbation and jitter before and after taking food. The average RAP and jitter of the non-aspiration group were significantly better than the aspiration group′s averages before eating. After eating, however, significant differences were observed only in average jitter.Conclusions:Analyzing perturbation and jitter can help to identify persons at risk of aspiration.

The literature quality was evaluated by 4 personnel, and the included literature was extracted and summarized by 2 personnel.Result:Finally, 7 articles were included, including 1 clinical decision, 3 guidelines, 2 RCTs and 1 quasi-experimental study. A total of 12 pieces of evidence were extracted from 5 aspects, such as evaluation, intervention measures, supervision, professional knowledge training of nursing staff and principles of prevention and compliance.Conclusions:The best evidence for the prevention of pressure injury in adult ARDS patients with prone mechanical ventilation summarized in this study is convenient for clinical nurses to conduct more targeted and scientific evaluation and care of pressure injury for patients.

Objective:To explore the value of flexible endoscopic evaluation of swallowing (FEES) in guiding the decannulation of neurological disease patients with dysphagia after a tracheotomy.Methods:The FEES results of 188 neurological disease patients with dysphagia who had undergone a tracheotomy were analyzed retrospectively. The utility of FEES evaluation indexes (including glottis activity, the classification of pharyngeal secretions and residues as well as penetration-aspiration grade) for predicting the success of decannulation was explored.Results:One hundred and nine of the patients (the success group) were decannulated successfully and 79 (the failure group) were not, a success rate of 57%. The abnormal glottis activity rate among the failure group was 55%, significantly higher than among the success group (21%). The pharyngeal secretion classifications and penetration-aspiration grades among the success group were also significantly lower than among the failure group, on average. The average course of recovery from the tracheotomy was 184 days in the success group, significantly shorter than that of the failure group (292 days). No significant differences in residues were observed.Conclusion:The glottis activity, secretions and intake aspiration evaluated using FEES are of great value for guiding the decannulation of neurological disease patients with dysphagia after a tracheotomy.

Background: Endoscopic submucosal dissection has become the preferred treatment for early gastric cancer without lymph node metastasis (LNM). The risk of LNM is different among different pathological types of early gastric cancer. Aims: To investigate the risk factors of LNM in patients with early gastric cancer. Methods: The clinicopathological features of 1 093 early gastric cancer patients underwent radical gastrectomy and diagnosed by pathology from January 2005 to December 2019 at Nanjing Drum Tower Hospital and Nanjing Gaochun People's Hospital were retrospectively analyzed. Risk factors of LNM in patients with early gastric cancer were analyzed by univariate analysis and logistic regression model analysis. Results: A total of 1 093 patients with early gastric cancer were enrolled, and positive LNM was found in 154 patients (14.1%). Univariate analysis showed that gender, age, tumor size, tumor location, gross classification, depth of tumor invasion, vascular and nerve invasion, differentiation type, ulcers were related with LNM (P<0.05). Multivariate analysis showed that age (OR=1.654, 95% CI: 1.102-2.480, P=0.015), tumor location (OR=1.617, 95% CI: 1.227-2.131, P=0.001), differentiation type (OR=1.664, 95% CI: 1.205-2.298, P=0.002), depth of invasion (OR=1.569, 95% CI: 1.212-2.030, P=0.001), vascular invasion (OR=10.514, 95% CI: 6.353-17.401, P=0.000) were the independent risk factors of LNM in early gastric cancer. Conclusions: Age, tumor location, differentiation type, depth of invasion, and vascular invasion are the independent risk factors of LNM in early gastric cancer, especially vascular invasion. For patients with vascular invasion, if there are no contraindications, surgical intervention is recommended.

Primary biliary cholangitis (PBC) is a chronic cholestatic liver disease, and may progress to cirrhosis and associated with complications of end-stage liver disease. The immunological characteristic of PBC is the presence of anti-mitochondrial autoantibodies (AMAs), and some anti-nuclear antibodies (ANAs) have high specificity for the diagnosis of PBC. In recent years, it has been found that anti-gp210, anti-sp100 and anti-centromere antibodies are correlated with the severity of PBC, treatment response to ursodeoxycholic acid (UDCA) and poor prognosis. However, correlation between AMAs and disease progression of PBC is still in controversial. This article reviewed the progress in research on the influence of autoantibodies on biochemical response and prognosis of PBC.

Objective: To investigate the correlation between Toll like receptor 4 (TLR4) expression and apoptosis in periventricular leukomalacia (PVL) rat model induced by hypoxia-ischemia. Methods: One hundred and forty three-day-old sprague-dawley (SD) rats, which were divided into experimental group (ischemia-hypo-xia group) and control group (sham operation group) randomly, were used to establish a hypoxic model by ligating the right common carotid artery and inhaling gas mixtures with 60 mL/L oxygen and 940 mL/L nitrogen.The rats were killed 6 h, 12 h, 24 h, 3 d, 7 d after model reproducing and the brain tissues were used for the following experiments.The pathological changes and apoptosis of brain tissues were detected by way of hematoxylin and eosin (HE) staining and terminal deoxynucleotidyl transferase dUTP nick end labeling (Tunel) assay respectively, and TLR4 expression was detected by adopting immunohistochemistry and reverse-transcription polymerase chain reaction(RT-PCR). The data were analyzed by using the SPSS 19.0 software. Results: TLR4 expression in the modeling rat brain commenced to increase in 6 hours (0.541±0.069, 0.166±0.058)and reached the peak in 3 days(1.932±0.161, 0.300±0.039), and then began to decline in 7 days (1.242±0.109, 0.220±0.025) post hypoxia-ischemia.Compared with the control group, there were statistical significances at 6 h, 12 h, 24 h, 3 d and 7 d (all P<0.05). The apoptosis of brain ti-ssue cells in the modeling rat brain started to increase at 6 hours(21.33±3.50) and reached the peak in 3 days (35.97±4.20), and then began to decline in 7 days (31.02±4.22) post hypoxia-ischemia.Compared with the control group, there were statistical significance at 6 h, 12 h, 24 h, 3 d and 7 d (all P<0.05). The TLR4 expression was positively correlated with cell apoptosis (r=0.774, 0.575, all P<0.05). Conclusions In the rat model of PVL induced by hypoxia-ischemia, TLR4 is likely to injure the neural cell through apoptosis.
