Objective:This study investigates the influence of the apolipoprotein E ε4(APOE ε4)genotype on the relationship between glucose-lipid metabolism disorders and diabetes-related cognitive impairment(DCI).Methods:A case-control study was conducted involving 891 patients with type 2 diabetes mellitus(T2DM)with a mean age of(62.1±13.8)years, all of whom underwent elective surgery at the First Hospital of Shanxi Medical University between January 2017 and December 2022.Among these participants, 229 were diagnosed with DCI(case group), while 662 were cognitively normal(control group).Routine clinical information was collected, and peripheral venous blood samples were analyzed for glycated hemoglobin(HbA1c)and blood lipid levels.The single nucleotide polymorphisms rs429358 and rs7412 were analyzed to determine the presence of the APOE ε4 genotype.Stepwise Logistic regression was employed to identify independent risk factors for DCI, and subgroup analyses were performed to evaluate the effect of the APOE ε4 genotype on the relationship between HbA1c and blood lipid levels in relation to DCI risk. Results:Among all patients, female gender( OR=1.915, 95% CI: 1.393-2.631, P<0.001), longer duration of T2DM( OR=1.169, 95% CI: 1.087-1.257, P<0.001), elevated triglycerides( OR=1.161, 95% CI: 1.041-1.294, P=0.007), and being an APOE ε4 carrier( OR=1.638, 95% CI: 1.115-2.405, P=0.012)were identified as independent risk factors for developing DCI.High levels of low-density lipoprotein(LDL)were found to be independently associated with an increased risk of DCI specifically in APOE ε4 carriers( OR=1.408, 95% CI: 1.060-1.870, P=0.018), but not in non-APOE ε4 carriers( P>0.05).In contrast, elevated HbA1c was independently associated with a higher risk of DCI in non-APOE ε4 carriers( OR=1.220, 95% CI: 1.040-1.430, P=0.014), but not in APOE ε4 carriers( P>0.05).Additionally, elevated triglycerides were independently linked to an increased risk of DCI across the entire sample and within each APOE ε4 genotype subgroup. Conclusions:The APOE genotype plays a significant role in modulating the relationship between dyslipidemia and the risk of developing DCI.This highlights the critical importance of lipid metabolism disorders and APOE risk genes in both the development and progression of DCI.These findings offer valuable insights for future clinical and mechanistic studies focused on DCI.

Calciphylaxis is a rare ischemic necrotic skin disease characterized by skin ischemia, necrosis, and severe pain. Histopathological features include systemic arteriolar media calcification, intimal fibrosis, and thrombosis. While calciphylaxis is predominantly found in uremic patients, there have been a few case reports in non-uremic patients. This article presented a case of a non-uremic patient with primary hyperparathyroidism who underwent parathyroidectomy and subsequently developed severe calciphylaxis. The patient presented with symptoms of lower limb dermatalgia and ulceration, consistent with the classic clinical features of calciphylaxis. Following a systematic therapeutic approach in accordance with the "Zhongda Scheme", a complete remission of the condition was achieved. At the same time, the authors reviewed the relevant literature on the risk factors and possible mechanisms of non-uremic calciphylaxis based on this case.

Objective: To investigate the distribution characteristics and functional genes of cariogenic bacteria in oral microorganisms of patients with type 2 diabetes mellitus and to improve the understanding of the relationship between type 2 diabetes mellitus and dental caries. Methods: The experimental group included 10 patients with type 2 diabetes treated in the Department of Endocrinology, the First Affiliated Hospital of Air Force Medical University. The normal control group included healthy oral subjects without type 2 diabetes in the community population (10 cases). Samples of supragingival plaque from patients with type 2 diabetes mellitus and normal controls were collected and sequenced. Bioinformatics and statistical analysis of cariogenic bacteria such as Streptococcus mutans, Lactobacillus, Actinomyces viscosus and Candida albicans were carried out. Results: There were slightly fewer cariogenic bacteria such as Streptococcus mutans, Lactobacillus, Actinomyces viscosus and Candida albicans in supragingival plaque samples of type 2 diabetic patients than in normal controls, but the difference was not statistically significant (P>0.05). The results of KEGG pathway functional metabolic differences showed that the metabolic pathways of D-arginine and D-ornithine metabolism, biofilm formation-Escherichia coli, carolactam degradation and arginine biosynthesis were more abundant in the T2DM group than in the normal control group, while metabolic pathways such as tyrosine metabolism, selenocompound metabolism and pyruvate metabolism showed the opposite trend. Conclusion There was no significant difference in the content of cariogenic microorganisms between type 2 diabetic patients and normal control group. The differential metabolic pathways of the functional genes indicated that an increase in the arginine metabolic pathway was beneficial to the maintenance of acid-base balance in the oral microecological environment.

As a neglected tropical disease defined by the World Health Organization (WHO), echinococcosis causes a huge public health burden. Understanding the disease burden due to echinococcosis facilitates the progress towards elimination of the disease. This review analyzes the advances in disease and economic burdens of echinococcosis, describes the status quo disease burden due to echinococcosis in different areas of the world, compares the difference between international and national studies on disease and economic burdens of echinococcosis, and discusses the shortcomings of the current international and national studies on disease burden of echinococcosis. Currently, the studies on disease burden of echinococcosis suffer from problems of few field survey data and lack of authoritative disability weights for echinococcosis, while the studies on economic burden of echinococcosis suffer from problems of lack of comprehensive study populations and indicators.

Objective:To explore the influencing factors of severe pneumonia in children with respiratory syncytial virus (RSV) infection.Methods:A retrospective case-control study was used to collect 210 children with RSV infected pneumonia admitted to Hebei Children′s Hospital from October 2017 to October 2020. Among them, 70 children with severe pneumonia were included in the severe pneumonia group, and 140 children with common pneumonia were included in the common pneumonia group; the baseline data and relevant laboratory indicators of the two groups were compared; Logistic regression was used to analyze the influencing factors of severe pneumonia in children infected with RSV.Results:The proportions of wheezing, congenital heart disease, respiratory failure, heart failure and pleural effusion of children in severe pneumonia group were higher than those in common pneumonia group, and the forced vital capacity (FVC) and forced expiratory volume in the first second (FEV 1) were lower than those in common pneumonia group (all P<0.05); the levels of C-reactive protein (CRP), CD8 + cells, RSV load and Beclin-1 in severe pneumonia group were higher than those in common pneumonia group, and the levels of CD4 + cells and 1, 25-dihydroxyvitamin D [1, 25-(OH) 2D] were lower than those in common pneumonia group (all P<0.05). After treatment, the levels of CRP, CD8 + cells and Beclin-1 in children with severe pneumonia were lower than those before treatment, and the levels of CD4 + cells and 1, 25-(OH) 2D were higher than those before treatment (all P<0.05). Multiple regression model analysis was established. The results showed that congenital heart disease, high CRP level, high CD8 + cells, high RSV load and high Beclin-1 level were risk factors for severe pneumonia in children with RSV infected pneumonia (all OR>1, P<0.05), and high CD4 + cells and 1, 25-(OH) 2D level were protective factors (all OR<1, P<0.05). Conclusions:Severe pneumonia in children with RSV infected pneumonia may be affected by congenital heart disease, CRP, CD4 + cells, CD8 + cells, 1, 25-(OH) 2D, RSV load and Beclin-1.

Objective:To investigate the clinical application of multimodal low-opioid combined with saphenous nerve block analgesia in elderly patients undergoing knee arthroplasty.Methods:This study is a randomized controlled study.A total of 60 elderly patients who underwent elective knee arthroplasty in the Department of Orthopedics, the First Hospital of Shanxi Medical University from January 2021 to December 2021 were selected and divided into 2 groups by numerical randomization: mode low opioid analgesia regimen group(observation group)and traditional analgesia regimen group(control group), 30 cases in each group.Observation group: (1)Preemptive analgesia: Oral celecoxib 200 mg, qd.from 3 days before surgery, the mini-mental state examination(MMSE)score was used to evaluate the cognitive function; (2)Intraoperative analgesia: After the prosthesis was installed, choose to inject analgesics around the knee joint(ropivacaine 200 mg, morphine 5 mg, epinephrine 0.25 mg, dexamethasone 5 mg/100 ml normal saline, also known as "cocktail" solution); (3)Postoperative analgesia: After the operation, continuous saphenous nerve block(0.2% ropivacaine, 2 ml/h)was performed under ultrasound guidance, and the dose of nerve block was adjusted according to the degree of rehabilitation training.Control group: no special treatment before and during the operation, traditional postoperative patient-controlled intravenous analgesia(PCIA)was used after the operation, the formula WAs as follows: sufentanil(2 μg/kg)+ flurbiprofen axetil(200-300 mg)+ Tropisetron(5-10 mg). The numerical rating scale(NRS)scores were observed and recorded 1 day before surgery, 6, 12, 24, and 48 hours after surgery; the time of the first active straight leg raising after surgery, the time of landing; the range of motion(ROM)of the knee joint 3, 7, and 14 days after surgery; the American Hospital for Special Surgery Knee Score(HSS)at 14 days, 1, 3, and 6 months after surgery; serum substance P(SP)and interleukin-6(IL-6)concentrations 1 day before surgery and 48 hours after surgery, and adverse events were recorded.Results:Compared with the control group, the patients in the observation group had lower NRS scores at 6, 12, 24, and 48 hours after the operation( t=27.705, 27.532, 21.739, 25.780, all P<0.05); the first active straight leg raising time and the time of landing earlier after the operation, and the knee joint at 3, 7, and 14 days after the operation, the range of motion(ROM)was better( t=35.496, 43.716, 3.766, 5.216, 6.009, all P<0.05). And the American hospital for special surgery knee score(HSS)was higher at 14 days, 1 month, and 3 months after surgery( t=19.247, 32.337, 22.651, all P<0.05), but there was no significant difference at 6 months after surgery.Simultaneously, the serum SP and IL-6 concentrations in the observation group 48 h after the operation were (431.0±11.3)ng/L and(11.9±2.7)ng/L, respectively.Compared with the control group(442.5±15.6)ng/L, (14.4±2.9)ng/L( t=5.362, 4.144, both P<0.05). Compared with the control group, which were lower than those in the incidence of postoperative nausea and vomiting was lower, the length of hospital stay was shorter in the observation group( χ2=4.630, t=3.311, P=0.031, 0.002), and the other indicators had no statistical differences(all P>0.05). Conclusions:Multimodal low-opioid combined with saphenous nerve block analgesia can significantly reduce perioperative pain in elderly patients undergoing knee arthroplasty, improve early postoperative mobility, and speed up postoperative functional recovery.

Objective: Metagenomic sequencing was used to explore the species composition and internal functional metabolic pathway of saliva and supragingival plaque microbial communities in healthy adults to provide a theoretical reference for the biological prevention and treatment of oral diseases. Methods: Saliva and supragingival plaque samples were collected from healthy adults, total DNA was extracted, and a metagenomic library was constructed. The qualified library was sequenced via metagenomics, and the sequencing data were analyzed using bioinformatics and statistics. Results : The main bacterial phyla in healthy oral samples were Proteobacteria (32.51%), Bacteroidetes (30.81%), and Actinobacteria (16.23%), and the main bacterial species were Corynebacterium matruchotii (3.84%), Haemophilus parainfluenzae (2.91%), and Prevotella melaninogenica (2.76%). The alpha diversity of the supragingival plaque group was higher than that of the saliva group, and there was a significant difference in the composition of the microbial community between the two groups (P<0.05). At the species level, Prevotella melaninogenica, Fusobacterium periodonticum, and Prevotella intermedia were more abundant in saliva samples than in supragingival plaque samples, while Corynebacterium matruchotii, Propionibacterium acidifaciens, and Rothia dentocariosa were more abundant in supragingival plaque samples than in saliva samples (P<0.05). High-quality gene sets of saliva and supragingival plaque in healthy adults were constructed based on metagenomic sequencing. The results of KEGG pathway functional metabolic differences showed that starch and sucrose metabolism, leucine and isoleucine degradation, and arginine biosynthesis in salivary microorganisms were more abundant than in supragingival plaque, while glycolysis/gluconeogenesis and carbon metabolism in supragingival plaque were more abundant than in saliva. Conclusion There are significant differences in the species composition and functional gene metabolic pathways of saliva and supragingival plaque microecology in healthy adults. The sensitivity of dominant species in different microecological regions to the identification of oral diseases may be different. In the microbiological study of oral diseases, appropriate samples should be selected according to different diseases.

Objective:To evaluate the pancreatic subclinical dysfunction after intensity-modulated radiation therapy (IMRT) for gastric cancer by analyzing biochemical indexes and pancreatic volume changes, and to reduce the dose of pancreas by dosimetric prediction and dose limitation.Methods:30 patients with gastric cancer who received 45 Gy postoperative adjuvant radiotherapy were retrospectively selected. The pancreas was delineated and its dose and anatomical relationship with planning target volume (PTV) were evaluated. Fasting blood glucose, serum lipase and amylase, and pancreatic volume changes before and after radiotherapy were analyzed. The correlation between the changes of biochemical indexes and volume and pancreatic dose was evaluated by Pearson analysis. The threshold of the dosimetric prediction was obtained by receiver operating characteristic (ROC) curve. Finally, the feasibility of dosimetric limitation in IMRT was assessed.Results:The pancreatic volume of 30 patients was 37.6 cm 3, and 89.0% of them were involved in PTV. D mean of the pancreas was 45.92 Gy, and 46.45 Gy, 46.46 Gy and 45.80 Gy for the pancreatic head, body and tail, respectively. The fasting blood glucose level did not significantly change. The serum lipase levels were significantly decreased by 66% and 77%(both P<0.001), and the serum amylase levels were significantly declined by 24% and 38%(both P<0.001) at 6 and 12 months after radiotherapy. Pancreatic volumes of 22 patients was decreased by 47% within 18 months after radiotherapy. ROC curve analysis showed that pancreatic V 45Gy had the optimal predictive value for the decrease by 1/3 of serum lipase and amylase levels at 6 months and serum amylase level at 12 months after radiotherapy, and the cut-off value was V 45Gy<85%. Pancreatic D mean yielded the optimal predictive value for the decrease by 2/3 of serum lipase level at 12 months after radiotherapy, and the cut-off value was D mean<45.01 Gy. After" whole pancreas" and" outside PTV pancreas" dose limit, V 45Gy of the pancreas was decreased by 11% and 7%, D mean of the pancreas was declined by 2% and 2%, and D mean of the pancreatic tail was decreased by 3%, respectively. Conclusions:Serum lipase and amylase levels significantly decline at 6 and 12 months after adjuvant radiotherapy for gastric cancer, and pancreatic volume is decreased significantly within 18 months after radiotherapy. Pancreatic V 45Gy<85% and D mean<45.01 Gy are the dose prediction values for the decrease of serum lipase and amylase levels. The dose can be reduced to certain extent by dosimetric restriction.

Objective:To investigate the prognosis of severe hyperbilirubinemia in full-term infants who met the exchange transfusion criteria and were treated by blood exchange transfusion and phototherapy.Methods:A total of 168 full-term infants with severe hyperbilirubinemia who met the criteria for exchange transfusion and were hospitalized in the Neonatology Department of seven tertiary hospitals in Hebei Province from June 2017 to December 2018 were retrospectively included. According to the treatment protocol, they were divided into two groups: exchange transfusion group (38 cases) and phototherapy group (130 cases). Two independent sample t-test and Chi-square test were used to compare the clinical manifestations and follow-up results between the two groups. Multivariate logistic regression was used to analyze the risk factors for poor prognosis. Results:Neonatal severe hyperbilirubinemia in the exchange transfusion and phototherapy group were both mainly caused by hemolytic disease [42.1%(16/38) and 29.2%(38/130)], sepsis [28.9%(11/38) and 11.5%(15/130)] and early-onset breastfeeding jaundice [15.8%(6/38) and 11.5%(15/130)]. Total serum bilirubin level on admission in the exchange transfusion group was significantly higher than that in the phototherapy group [(531.7±141.3) vs (440.0±67.4) μmol/L, t=3.870, P<0.001]. Moreover, the percentage of patients with mild, moderate and severe acute bilirubin encephalopathy in the exchange transfusion group were higher than those in the phototherapy group [15.8%(6/38) vs 3.8%(5/130), 7.9%(3/38) vs 0.8%(1/130), 13.2%(5/38) vs 0.0%(0/130); χ2=29.119, P<0.001]. Among the 168 patients, 135 were followed up to 18-36 months of age and 12 showed poor prognosis (developmental retardation or hearing impairment) with four in the exchange transfusion group (12.9%, 4/31) and eight in the phototherapy group (7.7%, 8/104). Multivariate logistic regression analysis showed that for full-term infants with severe hyperbilirubinemia who met the exchange transfusion criteria, phototherapy alone without blood exchange transfusion as well as severe ABE were risk factors for poor prognosis ( OR=14.407, 95% CI: 1.101-88.528, P=0.042; OR=16.561, 95% CI: 4.042-67.850, P<0.001). Conclusions:Full-term infants who have severe hyperbilirubinemia and meet the exchange transfusion criteria should be actively treated with blood exchange transfusion, especially for those with severe ABE, so as to improve the prognosis.

Objective:To evaluate whether the decrease in peripheral blood monocyte count was a potential predictor for neutropenia in patients with nasopharyngeal carcinoma and cervical cancer.Methods:The medical records of 95 patients with nasopharyngeal carcinoma and cervical carcinoma who received intensity-modulated radiation therapy (IMRT) combined with paclitaxel liposomes and platinum (TP) synchronous chemotherapy and presented with neutropenia in the Second Affiliated Hospital of Soochow University from January 2017 to December 2018 were retrospectively analyzed. Paired sample t-test was used to assess whether the number of days when the monocytes initially dropped/decreased to lowest level/eventually increased to normal value was significantly less than those of the neutrophils. In addition, the chi-square test was performed to determine the correlation between the degree of reduction in the absolute neutrophil count (ANC) and baseline absolute monocyte count (AMC). Results:The change trend of AMC was consistent with that of ANC in the two cycles of concurrent chemotherapy. The number of days when AMC initially decreased/decreased to the lowest level/finally increased to normal value was significantly less than that of ANC (4 d vs. 6 d, 4 d vs. 10 d, P<0.001; 5 d vs. 6 d, 6 d vs. 9 d, 7 d vs. 12 d, P<0.001). However, no correlation was found between the baseline level of monocytes and the degree of subsequent neutropenia [(AMC<0.4×10 9) vs.( AMC≥0.4×10 9)=32 vs. 63, P=0.172]. Conclusions:Decreased monocyte count is an important potential predictor for neutropenia and a significant indicator for guiding the next monitoring of neutrophil count and treatment with granulocyte colony-stimulating factor.
