Objective:To understand the status of hepatitis B detection, prenatal care and antiviral treatment for hepatitis B positive pregnant women, and to provide scientific basis for the elimination of mother-to-child transmission of hepatitis B.Methods:The information of hepatitis B positive maternal case registration cards in Hunan Province during 2021-2023 was collected from the National Integrated Prevention of human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS), syphilis and hepatitis B mother-to-child transmission (IPMTCT) information management system. The status of hepatitis B detection, demographic characteristics of hepatitis B positive pregnant women, delivery methods, antiviral drugs and so on were analyzed retrospectively.Results:The hepatitis B detection rate of pregnant women in Hunan Province from 2021 to 2023 was 99.99%(1 196 261/1 196 370), and the positive rate of hepatitis B decreased year by year (χ 2trend=37.570, P<0.001). The education level of 75 542 hepatitis B positive pregnant women was generally low, and most of them were middle schools (63.4%, 47 893 cases). The proportion of hepatitis B positive pregnant women diagnosed in early pregnancy increased year by year (χ 2trend=414.202, P<0.001). The delivery mode of hepatitis B positive pregnant women were mainly natural childbirth and elective cesarean section. The rate of hepatitis B positive pregnant women with high risk of mother-to-child transmission increased from 47.4%(924/1 949) to 80.9%(2 238/2 768) (χ 2trend=570.003, P<0.001). Conclusions:It is necessary to strengthen the health education of hepatitis B positive pregnant women, optimize the management process of antiviral treatment for hepatitis B positive pregnant women with high risk of mother-to-child transmission, and further improve the rate of antiviral treatment, so as to reduce the risk of mother-to-child transmission of HBV.

Objection:To evaluate the effects of the miniscrew supported removable palatal arch for maxillary molar distalization.Methods:33 patients with mild to moderate crowding teeth and maxillary protrusion were treated with the miniscrew supported remova-ble palatal arch.The lateral cephalograms and dental plaster models were taken at the beginning of the treatment(T0)and at the end of molar distalization(T1).The multicentre variables were measured and compared with statistical software.Results:Cephalometrics showed that the average distance(mm)of the firs molar distalization was 3.6(P＜0.001),molar distal tipping was 6°(P＜0.001)and molar intrusion(mm)was 0.6(P＜0.05).The measurements of right and left molar distalization on plaster models were 4.2 mm(P＜0.001)and 4.0 mm(P＜0.001)respectively,the width of dental arch was increased by 3.1 mm(P＜0.05).The data of distalization of the first molar showed no statistical difference between right and left side on plaster cast and between model and cephalometric meas-urements.On the right side the angle between the mesial-distal tips line and the middle line was increased by 1.6°(P＞0.05),on the left by 4.8°(P＜0.05).Conclusion:The none extraction therapy for mild to moderate crowding teeth and maxillary protrusion can be realized by miniscrew supported removable palatal arch distalization appliance.

Objective : To discuss the effectiveness and mechanism for movement of maxillary buccally transposed canines by using a door-shaped individualized dental archwire mechanic and to provide a reference for clinicians. Methods: Eight patients with unilateral maxillary transposed canines were enrolled. All patients were treated with door-shaped individualized archwires. Before treatment (T1) and after the crowns of the transposed canines were moved to the right buccal positions in the dental arch during the treatment (T2), orthopantomograms were taken both at T1 and T2 to compare the linear changes (distance changes of the crown and root apex) and angular changes to study the mechanisms of tooth movement. The probing depth and buccal crown height were measured using a periodontal probe to compare periodontal changes before treatment (T1) and after treatment (T3) between the transposed canines and contralateral canines. Results: All eight transposed canines were successfully brought back to their normal dental arch position but were made more buccal by using the door-shaped individualized dental archwire, with a mean of (11.5 ± 2.7) months. The average overall duration was (28.3 ± 4.7) months. The crown distance changes of the canines from T1 to T2 (8.1 mm) were greater than those of the root apexes (1.5 mm) (P<0.05). The mean angulation changes of the long axes of the canines were 17.5°. There was no significant difference in the depth of periodontal measurement and buccal crown height measurement between T1 and T3 (P>0.05). Conclusion The buccal movement of maxillary transposed canines under a door-shaped individualized dental archwire was effective and feasible. The movement pattern under this mechanism was controlled tipping.

Protein corona (PC) has been identified to impede the transportation of intravenously injected nanoparticles (NPs) from blood circulation to their targeted sites. However, how intestinal PC (IPC) affects the delivery of orally administered NPs are still needed to be elucidated. Here, we found that IPC exerted "positive effect" or "negative effect" depending on different pathological conditions in the gastrointestinal tract. We prepared polystyrene nanoparticles (PS) adsorbed with different IPC derived from the intestinal tract of healthy, diabetic, and colitis rats (H-IPC@PS, D-IPC@PS, C-IPC@PS). Proteomics analysis revealed that, compared with healthy IPC, the two disease-specific IPC consisted of a higher proportion of proteins that were closely correlated with transepithelial transport across the intestine. Consequently, both D-IPC@PS and C-IPC@PS mainly exploited the recycling endosome and ER-Golgi mediated secretory routes for intracellular trafficking, which increased the transcytosis from the epithelium. Together, disease-specific IPC endowed NPs with higher intestinal absorption. D-IPC@PS posed "positive effect" on intestinal absorption into blood circulation for diabetic therapy. Conversely, C-IPC@PS had "negative effect" on colitis treatment because of unfavorable absorption in the intestine before arriving colon. These results imply that different or even opposite strategies to modulate the disease-specific IPC need to be adopted for oral nanomedicine in the treatment of variable diseases.

Objective:To explore the current situation of nursing human caring in hospital wards and analyze its influencing factors, so as to facilitate the development of nursing human caring practice.Methods:From July to November 2022, a total of 107 hospitals were surveyed through stratified convenience sampling method, and 4 072 ward nursing managers were recruited to finish the general information questionnaire and the ward nursing human caring status questionnaire. The general information included the region, class and type of the hospital, etc. The ward nursing human caring status questionnaire included 38 items in 5 dimensions of nursing human caring system and process, humanistic quality and training of nursing staff, humanistic environment and facilities, human caring procedures and measures, and human caring quality evaluation and improvement, with a full score of 190 points. Descriptive statistics were used to analyze the general data, independent samples t-test, ANOVA and correlation analysis were used to analyze the factors influencing the current status of nursing human caring in the ward, while multiple linear regression analysis was used to conduct a multivariate analysis. Results:The score of nursing human caring in hospital wards was 156.91±27.78. Whether the hospital had carried out nursing human caring pilot(demonstration) wards, whether the ward had previously been a hospital nursing human caring pilot(demonstration) nursing unit, the type of ward, and whether nursing managers had participated in human caring training were the influencing factors of the implication of nursing humanistic caring in wards( P<0.05). Conclusions:The practice of nursing human caring in hospital wards is at a good level, but needs to be further strengthened. Nursing managers should take systematically strategies to promote the development of nursing human caring practice.

Objective: To explore the protective effects of folic acid on retinas and its anti-oxidative stress mechanism in diabetic mice. Methods: Thirty-two 16-week-old SPF degree male db/db mice were randomized into model group and folic acid group, and 16 matched C57BL/KsJ mice were used as controls.Folic acid was used to the mice by oral gavage once per day with the dose of 71 μg/kg (2 ml) for 60 days in the folic acid group, and the same volume of normal saline solution was used in the model group and control group in the same way.The activities, mental state, body weight, and fasting plasma glucose (FPG) of the mice were recorded during experiment.At the end of the intervention, the mice were sacrificed and the retinas and blood sample were obtained.The histopathology of the retinas was examined with hematoxylin- eosin staining; serum homocysteine (Hcy) was detected by ELISA assay; the relative expressions of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) mRNA were detected in the retinas by real-time fluorescence quantitative PCR; the relative expressions of B lymphoma 2 protein (bcl-2), bcl-2 related X protein (bax), 3-nitrotyrosine (3-NT) and 4-Hydroxynonine (4-HNE) proteins were assayed by Western blot assay; superoxide dismutase (SOD), 8-hydroxydeoxyguanosine (8-OHdG) and malondialdehyde (MDA) levels in the retinas were detected by biochemical kits, and immunofluorescence assay was used to detect the expression of NADPH oxidation 4 (NOX4) in the retinas.The use and care of the experimental animals adhered to the ARVO Statement by the American Association for Vision and Ophthalmology Research and this study protocol was approved by Ethic Committee of Qinghai University (QHDX 2018-35). Results: Over the experimental period, The FPG was normal and body weight was gradually increased in the mice of control group.The FPG>16.7 mmol/L and the mice appeared obese.In the folic acid group, both body mass and FPG of the mice were gradually reduced.At the end of drug administration, serum Hcy concentration of the mice was (27.18±3.18)μmol/L in the model group, which was significantly higher than (8.28±2.18)μmol/L in the control group and (13.73±2.54)μmol/L in the folic acid group (all at P<0.05). The retinal structure was intact in the control group, and the retinas were thinning with more capillaries and inflammatory cells in the model group, the thickness of the retinas was increased and the capillaries and inflammatory cells were decreased in the folic acid group.The relative expressions of TNF-α and IL-6 mRNA in the retinas were significantly higher in the model group than those in the control group, and those in the folic acid group were reduced in comparison with the model group (all at P<0.05). The relative expression of bcl-2 protein in the retinas of folic acid group was lower than that in the control group and higher than that in the model group, and the relative expressions of bax, 3-NT and 4-HNE proteins in the retinas of the folic acid group were significantly higher than those in the control group and lower than those in the model group (all at P<0.05 ). The T-SOD activity in the folic acid group was significantly stronger than that in the control group and weaker than that in the model group, and the concentrations of 8-OHdG and MDA in the retinas of the folic acid group were significantly reduced in comparison with those of the control group and elevated in comparison with those of the model group (all at P<0.05). The expressing intensity of NOX4 protein in the retinas of the folic acid group was significantly weaker than that of the model group. Conclusions Folic acid appears aprotective effect on retinal tissue in diabetic mice by reducing serum Hcy, inhibiting oxidative stress and cell apoptosis.

Objective: To systematically evaluate the efficacy of pressure therapy in treating patients with hypertrophic scars by meta-analysis. Methods: Databases including PubMed, Embase, Web of Science, and Cochrane Library were retrieved with the search terms"hypertrophic scar, hyperplastic scar, HTS, pressure therapy, pressure treatment, and the Chinese Journals Full-text Database was retrieved with the search terms in Chinese version"增生性瘢痕,瘢痕增生,肥厚性瘢痕,压力治疗,压力疗法"to obtain the publicly published randomized controlled trials about pressure therapy in the treatment of patients with hypertrophic scar from the establishment of each database to July 2017. The measurement indexes included the effective ratio, Vancouver Scar Scale (VSS) score, scar vascularity, scar hardness, scar pigment, scar thickness, and value of scar color (brightness, red, and yellow). RevMan 5.3 and Stata 12.0 statistical software were used to conduct a meta-analysis of eligible studies. Results: A total of 667 hypertrophic scar patients were enrolled in 11 articles, including 362 patients in pressure therapy group who received pressure treatment and 305 patients in untreated group who received no treatment. The bias risks of the 11 studies included were uncertain. Compared with those of untreated group, the effective ratio of patients in pressure therapy group was significantly increased, with the relative risk of 5.98 (95% confidence interval=1.83-19.46, P<0.01); the VSS score and scar vascularity of patients in pressure therapy group were obviously decreased, with weighted mean differences of -2.24 and -0.66 respectively (95% confidence interval=-4.16--0.33, -1.21--0.12, P<0.05); the scar hardness, scar pigment, scar thickness, and value of scar color (brightness, red, and yellow) of patients in pressure therapy group were not changed obviously (P≥0.05). Significant heterogeneity existed in the included studies of the effective ratio, VSS score, scar vascularity, scar hardness, scar pigment, and scar thickness, P<0.01, I²=90%, 87%, 80%, 93%, 86%, 94%. Pressure range might be the heterogeneity source of effective ratio, and pressure clothing combined with pressure pad therapy might be a heterogeneous source of VSS score. Sensitivity analysis showed that the combined effect size results were stable in the effective ratio and scar pigment, but not stable in the VSS score, scar thickness, scar hardness, and scar vascularity. There was no publication bias in the effective ratio, VSS score, scar hardness, scar pigment, and scar vascularity (P>0.1), while there was publication bias in the scar thickness (95% confidence interval=-19.77--3.30, P<0.1). Conclusions Compared with patients without treatment, in the treatment of hypertrophic scars, pressure therapy can obviously increase the effective ratio, reduce the VSS score and scar vascularity, but can not obviously improve the scar hardness, scar pigment, scar thickness, and value of scar color (brightness, red, and yellow).
