Psoriasis is a chronic inflammatory skin disease, and its pathogenesis is largely modulated by abnormal angiogenesis. Previous research has indicated that AlkB homolog 5 (ALKBH5), an important demethylase affecting N⁶-methyladenosine (m⁶A) modification, plays a role in regulating angiogenesis in cardiovascular and eye diseases. Our present study found that ALKBH5 was upregulated and co-localized with cluster of differentiation 31 (CD31) in the skin of IMQ group compared with control group. ALKBH5-deficient mice decreased IMQ-induced psoriatic dermatitis and exhibited histological improvements, including decreased epidermal thickness, hyperkeratosis, numbers of dermal capillary vessels and inflammatory cell infiltration. ALKBH5-KO mice alleviated angiogenesis in psoriatic lesions by downregulating the protein kinase B (AKT)/mammalian target of rapamycin (mTOR) pathway. Additionally, the expression of ALKBH5 was significantly upregulated in IL-17A-induced human umbilical vein endothelial cells (HUVECs), which further promoted the expression of angiogenesis-related cytokines and endothelial cell proliferation. Cell proliferation and angiogenesis were suppressed in ALKBH5 knockdown group, whereas ALKBH5 overexpression promoted these processes. The regulation of angiogenesis in HUVECs by ALKBH5 was facilitated through the AKT-mTOR pathway. Collectively, ALKBH5 plays a pivotal role in psoriatic dermatitis and angiogenesis, which may offer a new potential targets for treating psoriasis.

ObjectiveTo investigate the significance of different non-treatment thresholds or upper limits of normal （ULN） of alanine aminotransferase （ALT） in evaluating significant liver pathological injury in patients with chronic hepatitis B virus （HBV） infection， and to provide guidance for clinical diagnosis and treatment. MethodsThis study was conducted among 733 patients with chronic HBV infection who were hospitalized in Ningbo No. 2 Hospital from January 2015 to December 2023 and underwent liver biopsy and histopathological examination， and all patients had a persistent ALT level of ≤40 U/L and positive HBV DNA （>30 IU/mL）. According to the treatment threshold or ULN of ALT， the patients were divided into group 1 with 575 patients （≤35 U/L for male patients， ≤25 U/L for female patients）， group 2 with 430 patients （≤30 U/L for male patients， ≤19 U/L for female patients）， group 3 with 443 patients （≤27 U/L for male patients， ≤24 U/L for female patients）， group 4 with 446 patients （≤25 U/L）， group 5 with 158 patients （>35 U/L for male patients， >25 U/L for female patients）， and group 6 with 145 patients （>30 — ≤35 U/L for male patients， >19 — ≤25 U/L for female patients）. Groups 2， 5， and 6 were compared to analyze the severity of liver pathological injury in patients with different ALT levels and the constituent ratio of patients with significant liver pathological injury， and groups 1， 2， 3， and 4 were compared to investigate the value of different ULN or non-treatment thresholds of ALT in determining liver inflammation grade （G）， liver fibrosis stage （S）， and the treatment indication based on liver pathology. The independent-samples t test was used for comparison of normally distributed continuous data between two groups； a one-way analysis of variance was used for comparison between multiple groups， and the least significant difference t-test or the Tambane’s test was used for further comparison between two groups； the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups， and the Kruskal-Wallis H test was used for comparison between multiple groups and further comparison between two groups； the chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups； a Ridit analysis was used for comparison of ranked data. A multivariate Logistic regression analysis （forward stepwise） was performed with whether liver pathology met the treatment indication （≥G2 and/or ≥S2） as the dependent variable and related factors with a significant impact on the dependent variable （P <0.05） as the independent variable. The receiver operating characteristic （ROC） curve was plotted， and the area under the ROC curve （AUC）， as well as sensitivity， specificity， positive predictive value， negative predictive value， positive likelihood ratio， and negative likelihood ratio， was used to assess the diagnostic value of different non-treatment thresholds of ALT. ResultsAmong the 733 patients， 259 （35.33%） had ≥G2 liver inflammation， 211 （28.79%） had ≥S2 liver fibrosis， and 306 （41.75%） had treatment indication （≥G2 and/or ≥S2）. There was a significant difference in liver inflammation grade （G0 — G4） between groups 2， 5， and 6 （χ²=22.869， P <0.001）， and there were also significant differences in the constituent ratios of patients with ≥G2 or ≥G3 liver inflammation between the three groups （χ²=21.742 and 14.921， P<0.001 and P=0.001）. There was a significant difference in liver fibrosis stage （S0 — S4） between groups 2， 5， and 6 （χ²=16.565， P<0.001）， and there were also significant differences in the constituent ratios of patients with ≥S2， ≥S3 or S4 liver fibrosis between the three groups （χ²=13.264， 13.050， and 6.260， P=0.001， 0.001， and 0.044）. There were significant differences between groups 2， 5， and 6 in the constituent ratios of patients with or without treatment indication based on liver pathology （χ²=20.728， P<0.001）. There were significant differences between groups 2， 5， and 6 in the constituent ratio of male patients （χ²=24.836， P<0.05）， age （F=5.710， P<0.05）， ALT （F=473.193， P<0.05）， aspartate aminotransferase （AST） （F=107.774， P<0.05）， ALT/AST ratio （F=40.167， P<0.05）， γ-glutamyl transpeptidase （GGT） （H=15.463， P<0.05）， aspartate aminotransferase-to-platelet ratio index （APRI） （H=63.024， P<0.05）， and LIF-5 （5 indicators for liver inflammation and fibrosis） （H=46.397， P<0.05）. In groups 1 — 4， compared with the patients without treatment indication， the patients with treatment indication had a significantly lower constituent ratio of patients with positive HBeAg， significantly lower levels of platelet count （PLT） and HBV DNA， and significantly higher age， ALT， AST， GGT， APRI， FIB-4， and LIF-5 （all P<0.05）. The Logistic regression analysis showed that age （odds ratio ［OR］=1.044， 95% confidence interval ［CI］： 1.025 — 1.063， P<0.001）， GGT （OR=1.022， 95%CI： 1.007 — 1.038， P=0.003）， and HBV DNA （OR=0.839， 95%CI： 0.765 — 0.919， P<0.001） were influencing factors for treatment indication based on liver pathology in group 1； HBeAg （OR=1.978， 95%CI： 1.269 — 3.082， P=0.003）， age （OR=1.048， 95%CI： 1.025 — 1.071， P<0.001）， GGT （OR=1.016， 95%CI： 1.001 — 1.031， P=0.041）， and PLT （OR=0.995， 95%CI： 0.991 — 1.000， P=0.049） were influencing factors in group 2； age （OR=1.040， 95%CI： 1.014 — 1.066， P=0.002）， ALT （OR=1.047， 95%CI： 1.005 — 1.092， P=0.029）， HBV DNA （OR=0.817， 95%CI： 0.736 — 0.907， P<0.001）， and LIF-5 （OR=7.382， 95%CI： 1.151 — 47.330， P=0.035） were influencing factors in group 3； age （OR=1.054， 95%CI： 1.031 — 1.077， P<0.001）， ALT （OR=1.061， 95%CI： 1.016 — 1.107， P=0.008）， and HBV DNA （OR=0.825， 95%CI： 0.743 — 0.917， P<0.001） were influencing factors in group 4. The diagnostic performance for identifying ≥G2 liver inflammation， ≥S2 liver fibrosis， and treatment indication in groups 1 — 4 had an AUC of >0.7； group 1 showed the lowest sensitivity （28.76%） and the highest specificity， positive predictive value， positive likelihood ratio， and negative likelihood ratio in judging treatment indication； group 2 had the highest sensitivity and negative predictive value and the lowest negative likelihood ratio； groups 3 and 4 had similar diagnostic indicators. ConclusionIn patients with chronic HBV infection and a persistently low ALT level， the severity of liver histopathological injury and the constituent ratio of significant liver histopathological injury decrease with the reduction in ALT level. A higher non-treatment threshold or ULN of ALT can help to identify the patients requiring treatment （with a higher specificity）， while a lower non-treatment threshold or ULN of ALT can help to identify the patients who do not require treatment （with a higher sensitivity）.

Objective: To investigate the daily learning time status of elementary school students and understand the implementation of Health Requirements of Daily Learning Time for Secondary and Elementary School Students (GB/T 17223-2012) in schools, so as to provide a reference for strengthening and improving school health and health education in the new era. Methods: A stratified cluster random sampling method was used to select 7 776 primary school students in Shandong Province, and a survey questionnaire was designed based on the Health Requirements for Dayily Learning Time for Secondary and Elementary School Students(GB/T 17223-2012) standard to investigate their daily learning arrangements, sleep and physical activities, and breaks between classes. Comparison of intergroup differences were used by Chi square test and Kruskal-Wallis H test. Results: About 55.88 % of primary school students for daily learning time met the standard. There was a statistically significant difference in the daily learning time achievement rate among primary school students in three grades for first and second grade, third and fourth grade and fifth and sixth grade ( Z=1 629.47, P <0.01), and the fifth and sixth grade had the highest proportion of achieving the standard (85.92%). Specifically, the proportions of students whose class hours, class numbers and morning reading time meeting the standards were 30.07%, 10.20% and 42.19%, respectively. The sleep deficiency rate of primary school studnets was 58.69%, and the physical activity deficiency rate was 65.78%; and there was a statistically significant difference in the rate of insufficient sleep time and physical activity time among primary school students of different grades ( χ 2=56.39, 95.95, P <0.01), with sixth grade students showing the highest rates for both sleep and physical activity deficiencies (64.35%, 73.37%). Additionally, 49.78% of students had recess time below the standard requirements. Conclusion The health status of daily learning time among primary school students in Shandong Province is poor, with insufficient implementation of school standards, and the implementation of standards needs to be further strengthened.

Objective:To study the risk factors of adverse pregnancy outcomes for the diagnosis and treatment of pregnancy after cesarean section complicated with placenta previa.Methods:A national multicenter retrospective study was conducted to select a total of 747 pregnant women with the third trimester singleton pregnancy after cesarean section complicated with placenta previa from 12 tertiary hospitals in January 1st to December 31st, 2018. The risk factors of severe adverse outcomes [hysterectomy, intraoperative blood loss ≥1 000 ml, intraoperative diagnosis of placenta accreta spectrum disorders (PAS)] in pregnant women with second pregnancy complicated with placenta previa after cesarean section were investigated by logistic regression analysis. The roles of prenatal ultrasonography and magnetic resonance imaging (MRI) in the prediction of PAS and severe adverse outcomes were observed. According to whether vascular intervention was performed (uterine artery embolization or abdominal aortic balloon occlusion), the pregnant women were divided into the blocked group and the unblocked group, and the maternal and infant perinatal outcomes between the two groups were compared.Results:(1) General information: the hysterectomy rate of 747 pregnant women with second pregnancy complicated with placenta previa after cesarean section was 10.4% (78/747), the intraoperative blood loss ≥1 000 ml in 55.8% (417/747), and PAS was confirmed in 47.5% (355/747). The incidence of uterine rupture was 0.8% (6/747). (2) Analysis of risk factors for severe adverse outcomes: based on binary unconditioned logistic regression univariate and multivariate analysis, the risk factors for hysterectomy were the mode of vascular embolization and intraoperative blood loss. The probability of hysterectomy with uterine artery embolization was 5.319 times higher than that with abdominal aortic balloon occlusion (95% CI: 1.346-21.018). The risk factors of intraoperative blood loss ≥1 000 ml were the number of cesarean section delivery, ultrasonography indicated PAS and suspected PAS, intraoperative PAS and complete placenta previa. The risk factors for intraoperative PAS were uterine scar thickness, ultrasonography indicated PAS and suspected PAS, MRI indicated PAS and suspected PAS, and complete placenta previa. (3) The roles of ultrasonography and MRI in predicting PAS: the sensitivity and specificity of ultrasonography in predicting PAS were 47.5% and 88.4%; the kappa value was 0.279 ( P<0.001), with fair agreement. The sensitivity and specificity of MRI to predict PAS were 79.2% and 97.8%, respectively. The kappa value was 0.702 ( P<0.001), indicating a good agreement. The intraoperative blood loss and hysterectomy rate of pregnant women with PAS indicated by ultrasonography and MRI were significantly higher than those with PAS only by ultrasonography or MRI. (4) Influence of vascular occlusion on pregnancy outcome: there were no significant differences in intraoperative blood loss and incidence of intraoperative bleeding ≥1 000 ml between the blocked group and the unblocked group (all P>0.05). There was no significant difference in intraoperative blood loss between the pregnant women with abdominal aortic balloon occlusion, uterine artery embolization and those without occlusion ( P=0.409). The hysterectomy rate of pregnant women with uterine artery embolization was significantly higher than those with abdominal aortic balloon occlusion [39.3% (22/56) vs 10.0% (5/50), P=0.001]. Conclusions:In the third trimester of pregnancy with placenta previa after cesarean section, MRI examination has better consistency in predicting PAS than ultrasonography examination. Ultrasonography examination combined with MRI examination could effectively predict the hysterectomy rate and intraoperative blood loss. Vascular occlusion could not reduce the amount of intraoperative blood loss. The hysterectomy rate of pregnant women with uterine artery embolization is higher than those with abdominal aortic balloon occlusion.

Objective:To study the risk factors of adverse pregnancy outcomes for induced abortion of cesarean scar pregnancy in midtrimester.Methods:A national multicenter retrospective study was conducted. A total of 154 singletons pregnant women with cesarean scar pregnancy during the second trimester induced abortion by various reasons in 12 tertiary A hospitals were selected, their pregnant outcomes were observed and the risk factors of serious adverse outcomes were analyzed with univariate and multivariate logstic regression; the role of ultrasound and MRI in predicting placenta accreta and severe adverse outcomes was evaluated, the effectiveness of uterine artery embolization (UAE) in preventing hemorrhage in pregnant women with and without placenta accreta was compared.Results:Among 154 subjects, the rate of placenta accreta was 42.2% (65/154), the rate of postpartum hemorrhage≥1 000 ml was 39.0% (60/154), the rate of hysterectomy was 14.9% (23/154), the rate of uterine rupture was 0.6% (1/154). The risk factor of postpartum hemorrhage≥1 000 ml and hysterectomy was placenta accreta ( P<0.01). For each increase in the number of parity, the risk of placenta accreta increased 2.385 times (95% CI: 1.046-5.439; P=0.039); and the risk of placenta accreta decreased with increasing ultrasound measurement of scar myometrium thickness ( OR=0.033, 95% CI: 0.001-0.762; P=0.033). The amount of postpartum hemorrhage and hysterectomy rate in the group with placenta accreta diagnosed by ultrasound combined with MRI were not significantly different from those in the group with placenta accreta diagnosed by ultrasound only or MRI only (all P>0.05). For pregnant women with placenta accreta, there were no significant difference in the amount of bleeding and hysterectomy rate between the UAE group [median: 1 300 ml; 34% (16/47)] and the non-embolization group (all P>0.05); in pregnant women without placenta accreta, the amount of bleeding in the UAE group was lower than that in the non-embolization group (median: 100 vs 600 ml; P<0.01), but there was no significant difference in hysterectomy rate [2% (1/56) vs 9% (3/33); P>0.05]. Conclusions:(1) Placenta accreta is the only risk factor of postpartum hemorrhage≥1 000 ml with hysterectomy for induced abortion of cesarean scar pregnancy in midtrimester; multi-parity and ultrasound measurement of scar myometrium thickness are risk factors for placenta accreta. (2) The technique of using ultrasound and MRI in predicting placenta accreta of cesarean scar pregnancy needs to be improved. (3) It is necessary to discuss of UAE in preventing postpartum hemorrhage for induced abortion of cesarean scar pregnancy in midtrimester.

Objective To investigate the intensity of HBsAg and HBcAg expression in liver tissue of patients with chronic hepatitis B virus (HBV) infection and its clinical significance.Methods A total of 994 HBV infected patients underwent liver biopsy and histopathological examination.The expression of HBsAg and HBcAg in liver tissue was detected by histoimmunochemistry.Patients were divided into HBeAg (+)/HBVDNA(+), HBeAg(-)/HBV DNA(+) and HBeAg(-)/HBV DNA(-) groups according to HBeAg and HBV DNA levels;patients were divided into ＜2 × normal (ULN) group, 2-＜5 × ULN groupand ≥5 × ULN group according to the alanine aminotransferase (ALT) levels.The histologic activity (A), fibrosis (F), the expression of HBsAg and HBcAg in liver tissue and their correlations with clinical features were analyzed.Logistic regression analysis was used to study the factors affecting the expression of HBsAg and HBcAg in liver tissue.Results Among 994 HBV infected patients, 941 cases (94.67％) were intrahepatic HBsAg positive and 553 cases (55.63％) were intrahepatic HBcAg positive;403 cases (40.85％) were ≥A2 in histologic activity and 371 cases (36.09％) were ≥F2 in fibrosis.The degree of A and F was the highest in HBeAg (-) / HBV DNA (+) group, followed by HBeAg (-) / HBV DNA (-) group, and was the lowest in HBeAg (+) / HBV DNA (+) group.The intensity of intrahepatic HBsAg expression was significantly different among three groups (x2 =6.299, r =-0.760, P ＜ 0.05), however, the difference was not showed in pairwise comparisons.The difference of intrahepatic HBcAg intensity among three groups was statistically significant (x2 =282.995, r =-0.645, P ＜ 0.01), the intensity was the highest in HBeAg (+) / HBV DNA (+) group and the lowest in HBeAg (-) / HBV DNA (-) group.The constituent ratio of HBeAg positive and HBV DNA level were higher and the average age was lower in intrahepatic HBsAg positive group than those in HBsAg negative group.The constituent ratio of positive HBeAg, the levels of ALT, AST, PLT and HBV DNA were higher and the average age, the average FIB-4 level were lower in intrahepatic HBcAg positive group than those in HBcAg negative group.The HBV DNA level was an independent risk factor for intrahepatic HBsAg intensity, and the HBeAg positive and HBV DNA level were independent risk factors for intrahepatic HBcAg intensity.There were no significant differences in A and F among different groups of intrahepatic HBsAg intensity (x2 =1.943 and 2.630, both P ＞ 0.05).There was significant difference in F among different groups of intrahepatic HBcAg intensity (x2 =12.352, P ＜ 0.01), but not in A.The degree of F was the highest in intrahepatic HBcAg negative group.There was significant difference in intrahepatic HBcAg intensity among different groups of ALT level (x2 =16.349, P ＜ 0.01), but not in intrahepatic HBsAg intensity.The intrahepatic HBcAg intensity in ALT ＜ 2 × ULN group was lower than that in other two groups.Conclusions Most of patients with chronic HBV infection are intrahepatic HBsAg positive and more than half of them are intrahepatic HBcAg positive.The intrahepatic HBsAg intensity is not associated with A and F, but correlates with HBV DNA level.The intrahepatic HBcAg intensity is not associated with A, but it is negatively correlated with F and positively correlated with positive HBeAg expression, HBV DNA level and ALT level.

Objective To assess the therapeutic effect of high-frequency repetitive transcranial magnetic stimulation (rTMS) combined with neuromuscular electrical stimulation (NMES) on poststroke dysphagia.Methods A total of 90 patients with poststroke dysphagia were enrolled.They were randomly divided into either a NMES + rTMS group or a NMES + sham rTMS group (n =45 in each group).The Kuhota water drinking test and Standardized Swallowing Assessment (SSA) were used to assess the swallowing function.Results The scores of Kuhota water drinking test (F=82.001,P＜0.001) and the SSA (F =33.743,P ＜0.001) before treatment,treatment of one course,treatment of two courses,and at 3 months after treatment in the NMES + rTMS group had significant differences.Compared with before treatment,they were improved significantly for treatment of one course (P ＜0.01 and P ＜0.05,respectively),two courses (all P＜0.01),and at 3 months (all P＜0.01) after treatment.The scores of Kuhota water drinking test (F =53.647,P＜0.001) and the SSA (F=19.178,P＜0.001) in the NMES + sham rTMS group also had significant difference.Compared with before treatment,they had significant improvement for treatment of one course (all P ＜0.05),two courses (P ＜0.05 and P ＜0.01,respectively) and at 3 months (all P＜0.01)after treatment.The scores of Kuhota water drinking test for treatment of one course,two courses,and at 3 months after treatment (treatment of one course:t=2.217,P=0.02;treatment of two courses:t =2.406,P =0.019;at 3 months after treatment:t =2.128,P =0.037) and the SSA (treatment of one course:t =2.196,P =0.030,treatment of two courses:t =2.425,P =0.016;at 3 months after treatment:t =2.512,P=0.013) in the NMES + rTMS group were significantly better than those in the NMES + sham rTMS group.Conclusions High-frequency rTMS combined with NMES may significantly improve the swallowing function in patients with stroke.Its efficacy is superior to NMES.

To detect the expression of miR-221/222 in serum and plasma cells in patients with monoclonal gammopathy of undetermined significance(MGUS) and multiple myeloma(MM), and to explore the possibility of miR-221/222 as biomarkers in the diagnosis and prognosis predicting of MGUS and MM.Bone marrow and serum samples from 14 patients with newly diagnosed MGUS, 81 patients with newly diagnosed or relapsed MM and 10 controls were collected from Sir Run Run Shaw Hospital of Zhejiang University and Tongde Hospital of Zhejiang Province during January 2013 and December 2015. The expressions of miR-221/222 in serum and in sorted CD138 positive plasma cells were detected by qRT-PCR, and the relative expression of miR-221/222 (Δct) was compared between the groups. Serum levels of miR-221 before and after treatment were compared in both remission group (=22) and refractory group (=13) in MM patients, and its correlation with serum level of β-MG was assessed using Pearson's correlation analysis.Serum levels of miR-221/222 in MGUS and MM groups were significantly higher than those in control group (all<0.01), while miR-221/222 levels in plasma cells were significantly lower in MGUS and MM groups than those in the control group (<0.05 or<0.01). No significant difference in miR-221/222 levels in serum and plasma cells was observed between MGUS group and MM group (all>0.05). There was no correlation between miR-221/222 levels in serum and plasma cells (=0.024 and -0.127, all>0.05), but miR-221 levels were correlated with miR-222 levels in both serum and plasma cells (=0.534 and 0.552, all<0.01). Receiver operating characteristic (ROC) curves showed that the areas under the curve (AUCs) of serum miR-221/222, plasma cell miR-221/222 in diagnosis of MGUS/MM were 0.968, 0.976, 0.801 and 0.727, respectively. There was no significant difference in serum level of miR-221 among MM patients with different paraprotein isotypes (>0.05), but serum level of miR-221 in patients with relapsed MM was higher than that in patients with newly diagnosed MM (<0.01). Compared with the patients with MGUS or MM stageⅠ and Ⅱ, patients with MM stage Ⅲ were of higher serum levels of miR-221 (<0.01). Serum level of miR-221 decreased after chemotherapy in the remission group (=51.5,<0.01), but such decrease was not observed in the refractory group (=67.5,>0.05). Serum level of β-MG was positively correlated with serum level of miR-221 (=0.524,<0.01).miR-221/222 in serum and plasma cells may be biomarkers for early diagnosis of MGUS, and are helpful for diagnosis and efficacy evaluation of MM.

Objective To practice the distance nursing and healthcare through mobile care clinic, and to provide a higher quality of specialist care to colostomy patients. Methods 76 colostomy patients who were operated during August 2015 to January 2016 were investigated and randomly divided into the intervention group ( n=40) and the control group ( n=36 ) . Based on the conventional nursing care, the intervention group received additional continuing care including the subsequent visit and telephone follow-up with the help of mobile care clinic. After one month of intervention, patients′satisfaction level and their awareness of health knowledge were surveyed using an autonomous questionnaire. Results The intervention group had much higher level of satisfaction compared to the control group [ ( 98. 4 ± 1. 6 ) vs ( 91. 3 ± 1. 7 ); t=18. 75, P<0. 05 ] . They also performed better wound care and knowledge awareness compared to the control group ( 92. 5% vs 69. 4%;82. 50% vs 58.33%; χ2=6.70, 5.38; P<0.05). Furthermore, the intervention group had significantly fewer cases of fecal dermatitis than the control group (2 vs 11; χ2=8.73,P<0.05).Conclusions With the help of home health care platform and mobile care clinic, more professional nursing guidelines can be provided in time. It can also improve the nursing satisfaction and reduce related compliances.
