Objective To investigate the effect of active silver ions liquids on incontinence of patients with cerebrovascular diseases.Methods Forty-eight patients with incontinence from cerebrovascular diseases were randomly divided into the treatment group and control one in equal number:the control group was managed with washing and cleaning the perineum with warm water in the morning and evening and the treatment group with active antibacterial liquid silver ion liquids in the afternoon once a day.The two groups were compared in terms of red swelling,itching,papula,blister,local shallow ulcer and abscess in the skin around the perineum as well as the incidence of urinary system infections.Results The treatment group had significantly lower incidences of red swelling,itching,papula,blister,local shallow ulcer and abscess in the skin around the perineum as well as the incidence of urinary system infections,as compared to the control group(all P<0.05).Conclusion Cleaning perineum with active silver ions liquids is effective for the prevention of infections in the skin around the perineum and urinary system infections.

Traditional Chinese medicine considers that the final purpose of acupuncture treatment for disease is to harmonize yin and yang. Acupuncture redresses a balance between yin and yang by transmitting information to acupoints and then to corresponding visceral tissues and organs and the brain through the meridian system or the nervous system. In recent years, scholars at home thoroughly studied heart rate variability (HRV) analysis for acupuncture treatment of diseases and found that the regulating effect of acupuncture on visceral organs was closely related to autonomic nerves and acupuncture could restore a balance between sympathetic and parasympathetic nerves. Many scholars explored the effect of acupuncture on diseases related to autonomic nervous dysfunction by HRV frequency domain or time domain analysis and gained a certain achievements. This article summarizes recent years’ domestic studies on HRV-based analysis of acupuncture for diseases with autonomic nervous dysfunction and reviews the close relationship between autonomic nerves and diseases and the related mechanism of acupuncture action.

In this study, hollow fiber membrane extraction combined with ambient ionization mass spectrometry ( AMS) was developed for the simultaneous determination of 7 perfluorinated compounds ( PFCs) in aqueous solution, including perfluoroheptanoic acid ( PFHpA ) , perfluorooctanoic acid ( PFOA ) , perfluorooctane sulfonate acid ( PFOS ) , perfluorononanoic acid ( PFNA ) , perfluorodecanoic acid ( PFDA ) , perfluoroundecanoic acid ( PFUdA) , and perfluorododecanoic acid ( PFDoA) . PFCs were detected in negative ion mode using selective reaction monitoring ( SRM) mode. The extraction time and the pH value of extraction solution were optimized. 13 C4-PFOS and 13 C4-PFOA were used as internal standards for quantitative analysis. The method showed good linearity with correlation coefficient values ( r2 ) greater than 0. 991 for the seven target PFCs. With the exception of PFHpA, the limit of detection ( LOD) for other six PFCs was within ranges from 0. 8 to 2. 7 ng/L while the limit of quantitative (LOQ) was from 2. 7 ng/L to 8. 9 ng/L. The enrichment factor of five PFCs was more than two hundred. The developed method was applied to detect the seven PFCs in tap water and Pearl River water, and they were all not detected. The recoveries were within the ranges of 88. 5%-108. 3% and 94. 2%-116. 7% when 40 ng/L and 400 ng/L PFCs were spiked into tap water, respectively. In terms of the Pearl River water, the recoveries were within the ranges of 75. 0%-102. 6% and 81. 2%-97. 6% when 40 ng/L and 400 ng/L PFCs were spiked, respectively.

Future research will further consider other potential benefits of non-pharmacological interventions, such as emotional health and diabetes self-management behavior.

Objective To obtain a non-invasive subclinical hypothyroidism ( SCH) mouse model, and to explore microRNAs profile related to lipid metabolism in the model mice. Methods C57BL/6 male mice (8 weeks) were treated with methimazole ( MMI, 0. 08 mg/kg BW/d) to construct SCH mouse model. MicroRNAs profiling analysis was performed by real-time quantitative polymerase chain reaction ( qRT-PCR) . Results Compared with the control group, the serum thyroid stimulating hormone ( TSH ) in subclinical hypothyroidism group increased significantly (P>0.01), while the serum free thyroxine(FT4) level did not show significant difference between the two groups (P>0. 05), which was in line with the diagnostic criteria of SCH. SCH mice was accompanied by dyslipidemia and liver lipid metabolism disorders. Four lipid metabolism related miRNAs, miR-33, miR-122, miR-199a-5p, and miR-375 in the liver of SCH mice were significantly decreased compared with those of control ( P>0. 05). Conclusion The noninvasive SCH model generated by MMI and miRNAs profile provide an animal model and a molecular basis for the study of SCH related lipid metabolism disorders.

Objective:To compare the therapeutic effects of nasal high-flow oxygen therapy (HFNC) and nasal canal oxygenation (NCO) during breaks off non-invasive ventilation (NIV) for acute exacerbation of chronic obstructive pulmonary disease (AECOPD), and to explore the feasibility of NIV combined with HFNC in the treatment of AECOPD.Methods:From August 2017 to July 2019, AECOPD patients with type Ⅱrespiratory failure (arterial blood gas pH <7.35, PaCO 2 > 50 mmHg) who were treated with NIV were randomly (random number) assigned to the HFNC group and NCO group at 1:1. The HFNC group received HFNC treatment during breaks from NIV and the NCO group received low-flow NCO during the NIV interval. The primary endpoint was the total respiratory support time. The secondary endpoints were endotracheal intubation, duration of NIV treatment and breaks from NIV, length of ICU stay, total length of hospital stay and so on. Results:Eighty-two patients were randomly assigned to the HFNC group and the NCO group. After secondary exclusion, 36 patients in the HFNC group and 37 patients in the NCO group were included in the analysis. The total respiratory support time in the HFNC group was significantly shorter than that in the NCO group [(74 ± 18) h vs. (93 ± 20) h, P = 0.042]. The total duration of NIV treatment in the HFNC group was significantly shorter than that in the NCO group [(36 ± 11) h vs. (51 ± 13) h, P=0.014]. There was no significant difference of the mean duration of single break from NIV between the two groups, but durations of break from NIV in the HFNC group were significantly longer than those in the NCO group since the third break from NIV ( P < 0.05). The intubation rates of the HFNC and NCO groups were 13.9% and 18.9%, respectively, with no significant difference ( P=0.562). The length of ICU stay in the HFNC group was (4.3 ± 1.7) days, which was shorter than that in the NCO group [(5.8 ± 2.1) days, P=0.045], but there was no significant difference in the total length of hospital stay between the two groups. Heart rate, respiratory rate, percutaneous carbon dioxide partial pressure and dyspnea score during the breaks from NIV in the NCO group were significantly higher than those in the HFNC group, and the comfort score was lower than that in the HFNC group ( P<0.05). Conclusion:For AECOPD patients receiving NIV, compared with NCO, HFNC during breaks from NIV can shorten respiratory support time and length of ICU stay, and improve carbon dioxide retention and dyspnea. HFNC is an ideal complement to NIV therapy in AECOPD patients.

Objective:To observe the application effect of a self-designed assisted abdominal breathing rehabilitation device in elderly patients undergoing postoperative chemotherapy for lung cancer.Methods:Self-designed an assisted abdominal breathing rehabilitation device. Used the convenience sampling method, 116 elderly patients admitted to the First Affiliated Hospital of Anhui Medical University from April 2021 to April 2022 undergoing postoperative chemotherapy for lung cancer were selected as study subjects, and they were divided into control and observation groups by the random number table method, with 58 cases in each group. The control group received routine abdominal breathing training, and the observation group used auxiliary abdominal breathing rehabilitation device for abdominal breathing training, and compared the training compliance rate, lung function indexes and six minutes-walk test scores of the two groups before and after 2 weeks of training.Results:After 2 weeks of training, the training compliance rate of patients in the observation group was 100.00% (58/58), which was higher than 87.93% (51/58) in the control group, and the difference was statistically significant ( χ 2=7.45, P<0.05). After 2 weeks of training, FEV 1, FVC, FEV 1/FVC were (1.81 ± 0.29) L, (1.98 ± 0.32) L, (91.91 ± 5.98) % respectively in the observation group, and (1.49 ± 0.31) L, (1.73 ± 0.41) L, (87.11 ± 9.44) % respectively in the control group, there were statistically significant differences between the two groups ( t=-4.13, -2.60, -2.36, all P<0.05). After 2 weeks of training, the six minutes-walk test score was (0.86 ± 0.71) points in the observation group and (1.02 ± 0.74) points in the control group, and the difference was statistically significant ( t=2.05, P<0.05). Conclusions:An assisted abdominal breathing rehabilitation device helps to improve the training compliance rate, enhance lung function recovery and improve exercise endurance in elderly patients undergoing chemotherapy after lung cancer surgery.

AIM:To investigate the molecular mechanism of a novel bromobenzene substituted trifluoromethylbenzo Cyclopentanone WW02 inhib-iting the viability and proliferation of human lung cancer A549 and H1299 cells.METHODS:The ef-fect of different concentrations of WW02(6.25,12.5,25,50 μg/mL)on cell viability and prolifera-tion of A549 and H1299 were measured using CCK-8 and EdU methods.After 24 hours of stimulation of A549 and H1299 cells with different concentra-tions of WW02,the changes in Akt and mTOR phos-phorylation levels under different concentrations of WW02 were detected through Western blot as-say.Macromolecular docking was carried out be-tween WW02,AKT and mTOR through MOE Dock.RESULTS:After treating A549 and H1299 cells with WW02 using different concentrations(6.25,12.5,25,50 μg/mL),the activity of A549 and H1299 cells decreased in a concentration dependent manner compared with the DMSO control group(P<0.05).The proliferation of cells showed a concentration dependent decrease compared to the DMSO con-trol group(P<0.05).Compared with the DMSO con-trol group,after 24 hours of WW02 stimulation,the phosphorylation levels of Akt and mTOR in A549 cells decreased under the concentration of WW02(12.5,25,50 μg/mL,P<0.05).Compared with the DMSO control group,the phosphorylation levels of Akt and mTOR in H1299 cells decreased af-ter 24 hours of WW02 stimulation(25,50 μg/mL,P<0.05).Based on pattern analysis,it was found that WW02 had a strong binding with Akt and mTOR,with the highest score of-8.3 kcal/mol for WW02 and mTOR,while the highest score for WW02 and Akt was-7.3 kcal/mol.CONCLUSION:WW02 inhib-its the activity and proliferation of lung cancer A549 and H1299 cells,and its mechanism of action may be achieved by directly binding to Akt and mTOR proteins to inhibit Akt and mTOR phosphory-lation.

Objective This study aimed to identify PAX9 variants in non-syndromic tooth agenesis families of Chi-na,as well as to analyze the genotype-phenotype of non-syndromic tooth agenesis caused by PAX9 variants,which can provide a basis for the genetic diagnosis of tooth agenesis.Methods We collected the data of 44 patients with non-syn-dromic oligodontia who underwent treatment at Stomatological Hospital of Hebei Medical University between 2018 and 2023.Whole-exome sequencing was performed on the peripheral blood of the proband and its core family members,and the variants were verified by Sanger sequencing.Pathogenicity analysis and function prediction of the variants were per-formed using bioinformatics tools.The correlation between the genotype of PAX9 variant and its corresponding pheno-type was examined by reviewing 55 publications retrieved from PubMed.The studies involved 232 tooth agenesis pa-tients with PAX9 variants.Results A novel PAX9 c.447delG(p.Pro150Argfs*62)and a reported PAX9 c.406C>T(p.Gln136*)were identified in two Chinese families.Through bioinformatics analysis and three-dimensional structural mod-eling,we postulated that the frameshift variant was pathogenic.The outcome was the premature cessation of PAX9 pro-tein,which caused severe structural and functional deficiencies.Summarizing the PAX9 genotype-phenotype relationship revealed that patients carrying the PAX9 variant commonly led to loss of the second molars.Conclusion We identified the novel PAX9 c.447delG(p.Pro150Argfs*62)in a Chinese family of non-syndromic oligodontia,expanding the known variant spectrum of PAX9.The most susceptible tooth position for PAX9 variants of tooth agenesis was the second mo-lars and the deciduous molars during the deciduous dentition.

We retrieve and analyze the articles on body surface temperature of acupoints in the recent 50 years. Surface temperatures have been compared between acupoints and nonacupoints, and among acupoints in different states. The impacts of interventions for acupoint temperature are explored, including acupuncture,moxibustion and cupping, etc. We summarize the features and the rules of acupoint skin temperature. It is considered that there exists distribution rule for healthy people's acupoint skin temperature. That means acupoints have higher surface temperature than nonacupoints. In the same meridian the nearer acupoints close to the head and trunk, the higher the temperature is. The difference in symmetrical acupoints temperatures between the left and right side is about 0.5℃. In the different meridians the skin temperatures of adjacent acpoints are similar. The changes of acupoint's skin temperature in illness can be used as the auxiliary diagnosis. Acupuncture, moxibustion and cupping can produce acupoints stimulating, metabolism improving,balance, acupoint temperature regulating. Thus,diseases are relieved. The specificity and regularity that acupoint's skin temperature presents may be one of the manifestations of the acupoint specificity, also it is an important starting point of the research on acupoint sensitization. The further studies should consider different diseases and modern biological engineering techniques, so that more rules of acupoints temperature can be found by more sensitive and objective temperature measurements as well as experimental and the mathematical models.
