Background: Denture adhesives are alternatives used to improve retention, stability, comfort and satisfaction in patients with complete dentures. Evidence on the effectiveness of denture adhesives on resorbed mandibular ridges is scarce. Among the many commercially available denture adhesives, the ideal material for the severely resorbed mandibular ridge remains in dispute. Objective: The aim of this study was to evaluate the effectiveness of different quantities of four commercially available denture adhesives on the retention of mandibular complete dentures in severely resorbed ridges. Materials and Methods: A resorbed edentulous mandibular ridge model was manufactured in acrylic resin. A denture base was made and three loops were attached to it. Four commercially available denture adhesives (Fixodent, Perlie White, Fiftydent and Polident) were tested in amounts of 0.2 g, 0.4 g, 0.6 g, 0.8 g and 1.0 g. The acrylic resin model was evenly moistened with 1 ml of water and a weighted amount of adhesive material was applied to the denture base. The universal testing machine engaged the loops fixed on the denture base and applied the vertical displacement force. The maximum vertical displacement force values were recorded for each denture adhesive material at different amounts. Statistical calculation was performed using Kruskal Wallis with Bonferroni post hoc correction. Results: Statistically significant differences were observed in the mean values of the vertical displacement force for adhesive amounts of 0.2 g, 0.4 g, 0.6 g and 1.0 g (p<0.05) between the four adhesive materials tested. Statistically significant differences were observed when four denture adhesives were compared to each other in different amounts (p<0.05). Statistically significant differences were observed between different amounts for each of four denture adhesives (p<0.05). Conclusions: Among the four materials tested, Polident showed greater effectiveness at 0.6 g and 0.8 g, Fittydent at 0.6 g, 0.8 g and 1 g, Fixodent at 0.4 g and 0.6 g and Perlie White at 1 g and 0.8g quantity to resist vertical displacement. forces on the severely resorbed mandibular crest. Using an appropriate amount of denture adhesive allows for proper retention of the denture; Replacement of this adhesive is necessary once a day.

Objective:To construct a risk prediction model for urinary retention in patients undergoing radical cervical cancer surgery based on machine learning, and the prediction effect of the model was internally verified and evaluated, in order to provide reference for the early prevention and treatment of urinary retention in patients undergoing radical cervical cancer surgery.Methods:A total of 981 patients who underwent radical cervical cancer surgery in the First Affiliated Hospital of Anhui Medical University from June 2017 to February 2022 were selected and divided into the training set (687 cases) and the test set (294 cases) according to a ratio of 7∶3. Through literature review and risk factor analysis, the influencing factors of urinary retention after radical treatment of cervical cancer were explored, and the risk prediction model of urinary retention was constructed by using XGBoost, random forest, support vector machine and decision tree in machine learning. The accuracy rate, recall rate, F1 value and AUC of four machine learning algorithms were calculated by using the method of 10-fold cross-validation, and the model with the highest predictive efficiency was selected.Results:Among the 981 patients included, the incidence of urinary retention after radical cervical cancer surgery was 18.86% (185/981). The median age of urinary retention group was 51 years old, and that of non urinary retention group was 50 years old. Statistically significant variables in the univariate analysis and influencing factors summarized by literature review were featured, including patient age, intraoperative blood loss, body mass index (BMI), cancer stage, surgical method, surgical resection scope, whether pelvic lymph node dissection was performed, comorbidities and residual urine. Among the four model building methods of machine learning, the random forest model has the best effect, its training set F1 value was 0.94, the test set F1 value was 0.77, the ROC was plotted and the AUC was calculated to be 0.73. Age, intraoperative blood loss, BMI, cancer stage and surgical method contributed significantly to the classification of random forest model.Conclusions:The prediction model of urinary retention risk after radical cervical cancer surgery based on random forest method has the best efficacy. It is useful to help nursing personnel evaluate the risk of the uroschesis for a patient and then take targeted nursing interventions to actively prevent postoperative urinary retention.

Objective To provide a reference for avoiding the harm to critical target organs following considerable inhalation exposure to the transuranium element americium (Am) as well as post-accident decorporation or other radiation protection measures. Methods We established calculation programs based on the generic criteria for internal radiation emergency preparedness and response in the IAEA Safety Guide No.GSG-2 and current new ICRP biokinetic models and parameters, taking an inhalation of 241Am (activity mean aerodynamic diameter of 5 μm, σ = 2.5) by an adult worker as an example; and determined that the critical target organs were the lung AI region, red bone marrow, and the main source organs leading to acute doses to the critical target organs were the lung AI region, blood, and trabecular bone surface. Results The retention fractions in the main source organs over time after 241Am inhalation were calculated. Conclusion After being absorbed into blood, Am moves quickly to other parts, and Am of different absorption types shows similar early changes in retention fractions in blood: the retention fractions of Am of S, M, and F types in blood peak around 0.03 d, and then halve around 1.7 d. Inhaled Am shows different changes over time in retention fractions in the lung AI region and trabecular bone surface in the early stage: the retention fractions of S- and M-type Am in the lung AI region change little with time, while F-type Am transfers quickly from the lung to blood; In trabecular bone surface, S-type Am increases quickly in the first 7 d, M-type Am gradually increases mainly in the first 2 weeks, and F-type Am increases quickly in the first 2 d.

ObjectiveTo explore the clinical efficacy and safety of Fuzheng Huaji Longbi decoction in treating benign prostatic hyperplasia (BPH) in the patients with the syndrome of healthy Qi deficiency and blood stasis. MethodA total of 94 BPH patients were randomized into control and observation groups, with 47 patients in each group. The control group was treated with doxazosin mesylate sustained-release tablets, and the observation group with Fuzheng Huaji Longbi decoction on the basis of the therapy in the control group. After eight weeks, the international prostate symptom score (IPSS), quality of life (QOL) score, residual urine volume (RUV), maximum urinary flow rate (Qmax), TCM syndrome score, TCM symptom score, electrocardiogram, and liver and kidney function were determined to evaluate the clinical efficacy and safety of the two groups. ResultAfter 8 weeks of treatment, the total response rate in the control group was 63.64% (28/44), which was lower than that (84.44%, 38/45) in the observation group (χ2=5.026, P<0.05). The clinical efficacy in the observation group was higher than that in the control group (Z=-2.17, P=0.030). The treatment in both groups decreased the IPSS, QOL score, RUV, and TCM syndrome scores and increased the Qmax (P<0.05). Moreover, the observation group had lower IPSS, QOL score, RUV, and TCM syndrome score (P<0.05) and higher Qmax than the control group after treatment (P<0.05). The treatment in the observation group decreased all the TCM symptom scores (P<0.05), while that in the control group only decreased the frequency of urination at night and the scores of dysuria, weak urine stream, and post-urinary drainage (P<0.05). After treatment, the observation group had lower frequency of urination at night and lower scores of mental fatigue, cold limbs, lower abdominal discomfort, and loose stool than the control group (P<0.05). No adverse events associated with the administration of Fuzheng Huaji Longbi decoction were observed during the treatment period. ConclusionFuzheng Huaji Longbi decoction is effective in treating BPH in the patients with the syndrome of healthy qi deficiency and blood stasis. It can relieve the clinical symptoms and improve the quality of life, being a safe and reliable choice for clinical application.

BACKGROUND:Studies have shown that there are significant differences in the geometric morphology of the distal femur of different races and genders,and there are more short female patients in southern China,so the phenomenon of overhanging or insufficient coverage of imported knee prostheses often occurs during surgery. OBJECTIVE:To investigate the characteristics of distal femur bones in southern Chinese women and compare them with imported joint prostheses by simulating the three-dimensional reconstruction of the distal femur bone and matching the femoral side after osteotomy with common imported joint prostheses. METHODS:From January to December 2021,120 female volunteers underwent a CT scan of knee joints.The images were imported into Mimics 20.0 software in Dicom format for three-dimensional reconstruction and then imported into Magic 22.0 software to simulate osteotomy by posterior cruciate ligament preserved total knee arthroplasty and to conduct a matching study with a normal imported joint prosthesis. RESULTS AND CONCLUSION:(1)The functional anteroposterior dimension(fAP)of the distal femur and Persona matched prosthesis had a total overhang rate of 25%(30/120).The fAP≤47 mm group had an overhang than the other groups(P<0.05).The poor coverage rate of Triathlon prosthesis was 12.5%(15/120),and poor coverage was more likely in fAP>53 mm group than in fAP≤53 mm group(P<0.05).(2)The total poor coverage rate of femoral intercondylar width matching with Triathlon prosthesis was 27.5%(33/120).Therefore,the poor coverage rate of bone surface in the central region of the distal femur was more likely in the fAP≤47 mm group than in other groups(P<0.05).The overhang rate of Journey II was 21.6%(26/120),and the overhang rate was higher in the fAP>53 mm group than in the fAP≤53 mm group(P<0.05).(3)Journey II CR prosthesis had the largest difference with the length of the anterior mediolateral diameter of the femur,which was easy to hang out on the anterolateral side of the femoral prosthesis.The Persona CR prosthesis has the largest difference with the length of the posterior mediolateral diameter of the femur,which is easy to be poorly covered in the posterior medial part of the prosthesis.It is recommended to increase the femoral prosthesis with reduced mediolateral diameter in the fAP≤47 mm group and add wider and narrower sizes than the conventional size of intercondylar width,and optimize the anterolateral angular arc design of the femoral prosthesis to improve the matching of posterior cruciate ligament reserved knee prosthesis.

BACKGROUND:For teeth with normal dental crown height,pulp cavity retention crown restoration with different depths of the pulp cavity and different repair materials affects the stress and flexural strength of tooth tissue.For short crown molar defects,the research on pulp cavity repair mainly focuses on clinical observation and in vitro flexural strength experiments. OBJECTIVE:To establish a three-dimensional finite element model for short crown molar restored by the endocrown after root canal treatment to analyze the effects of different pulp cavity retention depths and different repair materials on the distribution and size of dentin equivalent stress. METHODS:Based on establishing the complete model of the short crown mandible first molar,a three-dimensional finite element model was established for repairing the distal adjacent defect of the short crown molar with different pulp cavity retention depths(h=2,3,4 mm)and different repair materials(zirconia,lithium disilicate).Under the oblique loading,the equivalent stress distribution was observed.The peak value of dentin equivalent stress and the mean value of equivalent stress near the bottom of the mesial pulp cavity wall were calculated. RESULTS AND CONCLUSION:(1)Equivalent stress concentration areas:The stress of complete short crown molar and restored models mainly concentrated in the mesial root mesial neck and mesial root lingual neck.The stress concentration area was found in the mesial pulp cavity wall corresponding to the bottom layer of restored models,and the stress concentration was obvious in the 4 mm retention depth group.(2)Under the same repair material,the peak value of dentin equivalent stress was the lowest at 3 mm for all models after repair.The average value of equivalent stress near the bottom of the mesial pulp cavity wall was lowest at 3 mm.(3)Under the same retention depth,there was no significant difference between the two materials in the dentin equivalent stress peak and the mean value near the bottom of the mesial pulp cavity.(4)The results showed that under the conditions of this experiment,the endocrown was used to repair the defect of the short crown molar and the retention depth was 3 mm,which was more beneficial to protect the remaining dental tissue.The selection of zirconia or lithium disilicate as the repair material had little effect on the dentin stress.

BACKGROUND:Repetitive magnetic stimulation of either S3 nerve root or M1 area can improve the urination function of patients with urinary retention after spinal cord injury,but there are few reports on the repetitive magnetic stimulation of both sites in patients with urinary retention after spinal cord injury. OBJECTIVE:To observe the effect of repetitive magnetic stimulation of both S3 nerve root and M1 area on urinary retention after spinal cord injury. METHODS:Forty patients with urinary retention after spinal cord injury were enrolled and were randomly divided into two groups(n=20 per group):group A(repetitive magnetic stimulation in both S3 nerve root and M1 area)and group B(repetitive magnetic stimulation in the S3 nerve root and sham stimulation in the M1 area).Patients in both groups were given 4-week repetitive magnetic stimulation based on conventional bladder function intervention.The stimulation time and duration of treatment were same in both groups,with a treatment time of 21 minutes daily,5 days per week,for 4 weeks in total.The urination diary and urodynamics were compared between two groups. RESULTS AND CONCLUSION:Before treatment,there were no statistically significant differences in the average daily catheterization times,average daily catheterization volume,average single urinary volume,urinary storage period(maximum bladder volume,bladder pressure),and urinary voiding period(detrusor pressure,residual urine volume)between the two groups(P>0.05).After 4 weeks of treatment,the average daily catheterization times in group A were lower than before treatment(P<0.05),while the average single urination volume in group A was higher than that before treatment(P<0.05);and the average daily catheterization times in group B were lower than before treatment(P<0.05).After 4 weeks of treatment,the average daily catheterization times in group A were lower than those in group B,and the average single urination volume was higher than that in group B(P<0.05).After 4 weeks of treatment,the maximum bladder volume and detrusor pressure during urination were increased in both groups compared with before treatment(P<0.05),while the bladder pressure and residual urine volume at the maximum volume of the two groups were decreased compared with those before treatment(P<0.05).Compared with group B,the maximum bladder volume and detrusor pressure during urination were higher in group A,while the bladder pressure and residual urine volume at maximum volume were lower in group A(P<0.05).To conclude,two treatments can both improve the urination function of patients with urinary retention after spinal cord injury,and repetitive magnetic stimulation of both S3 nerve root and M1 area is superior to repetitive magnetic stimulation of S3 nerve root alone.Repetitive magnetic stimulation of both S3 nerve root and M1 area can effectively improve the urination function of patients with urinary retention after spinal cord injury.

Particularly, a literature review and policy scan that were validated through key informant interviews with administrators and frontline health workers from selected urban and rural sites in the three main islands in the Philippines. These were framed into a background note to springboard the discussions during a national policy dialogue participated by representatives from key government organizations, professional organizations of physicians, nurses, and midwives, professional regulatory bodies, hospital administrators, frontline health workers, and donor agencies in the Philippines.</p><strong>RESULTS</strong><p style="text-align: justify;" data-mce-style="text-align: justify;">Deaths, burn-out, mental health problems, lack of personal protective equipment and poor allocation of vaccines were reported in the early phases of the pandemic. Support varied across settings but included additional allowance, free meals, accomodation, transportation, training and psychosocial services. Furthermore, pre-pandemic issues such as as low salaries and heavy workload continue to be the main reasons for leaving the workforce or the country. The proposed solutions are as follows: (1) creating policies and strategies for appropriate production, recruitment, and retention of human resources for health; (2) allocating regular permanent positions for both the education and health sector; (3) augmenting and continuation of deployment programs; (3) expanding roles of nurses to push for advanced practice nursing; (4) providing fair compensation along with risk allowances, non-financial incentives, and expanded benefits; (5) supporting mental health wellness by providing an appropriate work-rest balance and safe work environment; (6) providing opportunities for professional development and scholarships with accompanying return-service agreement; and (7) strengthening the reintegration programs for returning overseas health workers.</p><strong>CONCLUSION</strong><p style="text-align: justify;" data-mce-style="text-align: justify;">The pandemic has affected the well-being of health workers and disparities in support were reported due to longstanding workplace issues and policy implementation gaps. Stakeholder commitments require sustained monitoring while policies that are in place and yet to be developed demand stronger support from the government, members of Congress, the private sector, and other key decision-makers.</p>

To date, there have been limited reports on the efficacy of Kampo medicine in treating obsessive compulsive behaviors. To the best of our knowledge, there have been no previous reports on the efficacy of ryokeijutsukanto for obsessive compulsive behaviors. Here, we describe 2 cases of obsessive-compulsive behavior successfully treated with ryokeijutsukanto. Case 1 involved a 30-year-old female patient who presented with vague anxiety. As a result, she spent significant time engaging in compulsive behavior related to checking and was frequently tardy to work. She met the diagnostic criteria for obsessive compulsive disorder. We prescribed ryokeijutsukanto. Her compulsive behavior then improved from 40 minutes to 5 minutes in 56 days. Case 2 involved 57-year-old female patient who complained of not feeling refreshed in the morning. In addition, she had a feeling of gloom, daytime sleepiness and compulsive behavior of checking about 5 times whether windows were locked. We prescribed ryokeijutsukanto. In 14 days, her checking behavior then improved from 5 times to once. Other troublesome symptoms also improved. Ryokeijutsukanto is usually utilized for patients with fluid retention, dizziness, and qi counterflow. However, these 2 cases have qi stagnation rather than qi counterflow. These results suggested that ryokeijutsukanto could also be utilized to treat compulsive behaviors when patients had fluid retention, dizziness and qi stagnation.

ObjectiveTo investigate the effects of Linggui Zhugantang (LGZGT)-containing serum on primary astrocytes (AS) induced by β amyloid 1-42 (Aβ1-42) in a rat model of Alzheimer's disease (AD) and explore the phagocytic and degradative effects of LGZGT on Aβ. MethodAn AD model was established by inducing AS with Aβ1-42. The cells were divided into normal group, model group, LGZGT low-, medium-, and high-dose (LGZGT-L, LGZGT-M, and LGZGT-H) groups, and donepezil hydrochloride group. The model group was treated with Aβ1-42 at a final concentration of 10 μmol∙L-1. The LGZGT-L, LGZGT-M, and LGZGT-H groups were treated with 10% serum containing LGZGT on the basis of the model group. Cell viability was assessed using a cell counting kit-8 (CCK-8), lactate dehydrogenase (LDH) activity was measured using an LDH assay kit, and cell morphology was observed using an inverted microscope. The expression of Aβ-related degradation enzymes insulin-degrading enzyme (IDE) and cathepsin D (CTSD) was detected using Western blot, and the fluorescence intensity of cathepsin B (CTSB) was measured using immunofluorescence. The content of Aβ1-42 in cells was determined using an enzyme-linked immunosorbent assay (ELISA). ResultCompared with the normal group, the viability of AS in all groups decreased, and Aβ1-42 at different concentrations had inhibitory effects on AS proliferation. After administration, compared with the normal group, the cell survival rate of the model group decreased significantly (P<0.05). Compared with the model group, the cell survival rates of the LGZGT-H group and donepezil hydrochloride group increased significantly (P<0.05). The LDH activity of cells in the model group was significantly increased compared with that in the normal group (P<0.05), and cell bodies were swollen and enlarged with increased protrusions and elongation, suggesting more obvious cell damage. Compared with the model group, the LDH activity of cells in the donepezil hydrochloride, LGZGT-L, LGZGT-M, and LGZGT-H groups decreased significantly (P<0.05). After administration, the cell swelling in the LGZGT-M, LGZGT-H, and donepezil hydrochloride groups improved, cell protrusions shortened, and cell clustering decreased. Compared with the normal group, the expression of IDE and CTSD in the model group decreased significantly (P<0.05). Compared with the model group, the expression of IDE increased significantly in the LGZGT-M and LGZGT-H groups (P<0.05). Compared with the model group, the expression of CTSD increased significantly in the LGZGT-L, LGZGT-M, LGZGT-H, and donepezil hydrochloride groups (P<0.05). The average fluorescence intensity of CTSB in the model group was significantly lower than that in the normal group (P<0.05). Compared with the model group, the average fluorescence intensity of CTSD in the LGZGT-L, LGZGT-M, LGZGT-H, and donepezil hydrochloride groups increased significantly (P<0.05). The intracellular content of Aβ1-42 in cells in the model group was significantly higher than that in the normal group (P<0.05). After administration, compared with the model group, the intracellular content of Aβ1-42 in cells in the LGZGT-L, LGZGT-M, LGZGT-H, and donepezil hydrochloride groups decreased significantly (P<0.05), and LGZGT-containing serum reduced Aβ1-42 in a dose-dependent manner (P<0.05). ConclusionLGZGT has a protective effect on Aβ1-42-induced AS and can promote the degradation of Aβ. Its mechanism may be related to reducing Aβ toxicity, enhancing cell viability, promoting the expression of IDE, CTSD, and CTSB, and restoring lysosomal function.
Résumé
Tumor cells use glycolysis to provide material and energy under hypoxic conditions to meet the energy requirements for rapid growth and proliferation, namely the Warburg effect. Even under aerobic conditions, tumor cells mainly rely on glycolysis to provide energy. Therefore, glucose transporter protein 1(GLUT1), which is involved in the process of glucose metabolism, plays an important role in tumorigenesis, development and drug resistance, and is considered to be one of the important targets in the treatment of malignant tumors. In recent years, research on tumor glucose metabolism has gradually become a hot spot. It has been shown that various factors are involved in the regulation of tumor energy metabolism, among which the role of GLUT1 is the most critical. In this paper, the authors reviewed the latest research progress of GLUT1-targeted traditional Chinese medicine(TCM) active ingredient nano-delivery system in tumor therapy, aiming to reveal the feasibility and effectiveness of this system in the delivery of chemotherapeutic drugs. The GLUT1-targeted TCM active ingredient nano-delivery system can overcome the bottleneck of the traditional targeting strategy as well as the high-permeability long retention(EPR) effect. In summary, the authors believe that the GLUT1-targeted TCM active ingredient nano-delivery system provides a new strategy for targeted treatment of tumors and has a broad application prospect in tumor prevention and treatment.
