Objective: To analyze the prevalence trends of different types of elevated blood pressure and their association with nutritional status among primary and secondary school students in Inner Mongolia from 2019 to 2024, providing references for targeted prevention strategies. Methods: From September 2019 to 2024, a stratified random cluster sampling method was used to select 12 primary and secondary schools from each league city in Inner Mongolia Autonomous Region. A total of 177 108, 137 758, 190 182, 180 084 , 188 056, 180 351 primary and secondary school students (excluding grades one to three of primary school) were included for physical examination. The correlation between their nutritional status and high blood pressure was analyzed based on the basic situation of 129 821 primary and secondary school students who completed a questionnaire survey at the same time in 2024. Statistical analysis was conducted using a Chi-square test and multiple Logistic regression model. Results: From 2019 to 2024, the detection rates of elevated blood pressure were 13.60%, 13.68%, 17.60%, 17.24%, 14.77% and 15.96%, respectively. The rates for isolated systolic hypertension were 4.24%, 5.83%, 7.26%, 7.19%, 6.24% and 6.93%; isolated diastolic hypertension rates were 6.38%, 4.99%, 6.23 %, 6.41%, 5.39% and 5.66%; and combined systolic and diastolic hypertension rates were 2.97%, 2.86%, 4.11%, 3.65%, 3.14 % and 3.36%. Multivariate Logistic regression analysis showed that girls, junior high school, senior high school, overweight, and obesity were positively associated with elevated blood pressure risk ( OR =1.27, 1.25, 1.32, 1.66, 3.07, all P <0.05); conversely, county residence, Mongolian ethnicity, and other ethnicities showed negative associations ( OR =0.90, 0.93, 0.90, all P <0.05). Conclusions Overweight and obesity among children and adolescents are closely related to various types of elevated blood pressure. Prevention strategies should prioritize effectively controlling weight issues among children and adolescents, thereby effectively reducing the incidence of elevated blood pressure.

Digital technologies have become an integral part of complete denture restoration. With advancement in computer-aided design and computer-aided manufacturing (CAD/CAM), tools such as intraoral scanning, facial scanning, 3D printing, and numerical control machining are reshaping the workflow of complete denture restoration. Unlike conventional methods that rely heavily on clinical experience and manual techniques, digital technologies offer greater precision, predictability, and efficacy. They also streamline the process by reducing the number of patient visits and improving overall comfort. Despite these improvements, the clinical application of digital complete denture restoration still faces challenges that require further standardization. The major issues include appropriate case selection, establishing consistent digital workflows, and evaluating long-term outcomes. To address these challenges and provide clinical guidance for practitioners, this expert consensus outlines the principles, advantages, and limitations of digital complete denture technology. The aim of this review was to offer practical recommendations on indications, clinical procedures and precautions, evaluation metrics, and outcome assessment to support digital restoration of complete denture in clinical practice.

Objective:To explore the reconstruction strategy and technical selection of S3 hepatic vein with middle hepatic vein confluence in pediatric liver transplantation(LT)using living donor left lateral segment to lower the risk of vascular complications caused by variant grafts.Methods:From January 2015 to June 2021, retrospective analysis is performed for 840 consecutive cases of pediatric living donor LT using left lateral segment(LLS).There are 32 cases of S3 hepatic vein with middle hepatic vein confluence with an overall incidence of 3.81%.Individualized reconstruction strategies are implemented according to the specific conditions of variation and different interposition vessels available: group I unification venoplasty technique with interposition vein graft is employed for reconstructing HV from grafts, prolonged S3 is formed into a single opening with S2 and then anastomosed with recipient(21 cases); group Ⅱ dual HV reconstructions were performed(11 cases); venoplasty of recipients'LHV, MHV and inferior vena cava(IVC)is performed for creating a large orifice for anastomosis with S2 HV from graft and S3 is anastomosed with stump of recipient right HV directly or interposed blood vessels.Clinical features and prognosis of two groups, the incidence, treatment and prognosis of HVOO and the incidence of HVOO between variant and non-variant groups were compared.Results:The median follow-up time of variant group(32 cases)is 23.8 month with an incidence of HVOO at 15.6%.During the same period, the non-variant group incidence of HVOO is 4.5%.There is inter-group statistical difference( P=0.014).The only statistical difference between groups Ⅰ and Ⅱ is ultrasonic blood flow velocity of S3 HV at 14 POD [(39.15±16.37)vs(20.05±8.52)cm/s, P=0.001].HVOO occurred in 7 cases and 6 cases respectively in groupⅠ and group Ⅱ.There is no statistical difference( P=0.310).There are no intractable vascular complications.Long-term vascular patency of allogeneic and autologous interposition vein is satisfactory and there is no graft failure or mortality related to HVOO. Conclusions:Selecting strategies and techniques for reconstructing S3 hepatic vein with middle hepatic vein confluence at our center are reasonable, safe and effective.And the overall treatment efficacy is satisfactory.Reasonable selection of multidimensional reconstruction methods and accurate application of various technologies are conducive to improving patient prognosis.

Objective:To explore the relationship between serum lactate level and early prognosis after liver transplantation (LT) in children.Methods:Between January 1, 2018 and December 31, 2020, 675 pediatric LT recipients were recruited. Clinical data were retrospectively reviewed, early postoperative serum lactate level and clearance rate recorded and receiver operating characteristic (ROC) curve plotted for determining optimal cut-off values. The inter-group differences in early postoperative complications and patient/graft survival rates were compared.Results:According to ROC, blood lactate levels >1.99 mmol/L at 12 h postoperatively were associated with early postoperative graft loss (AUC 0.73, 95% CI: 0.62-0.84, P=0.01). Age and weight of recipients in high-level group were 7.17(5.70-10.40) month and 7.00(6.00-8.60) kg and both were significantly lower than those in low-level group [7.80(6.21-13.58) month and 7.20(6.45-9.00) kg]. The inter-group differences were statistically significant ( P=0.017, P=0.034). Blood plasma transfusion volume, red blood cell transfusion volume, portal vein pressure pre-closure, postoperative intensive care unit (ICU) stay, ventilator use time, early allograft dysfunction rate, early postoperative pulmonary infection rate and recipient mortality rate in high-level group were 400 (200-400) ml, 2.00 (2.00-4.00) U, (15.71±4.44) mmHg, 2.50(2.00-3.00) day, 3.81(2.47-8.50) hour, 22.95%(42/185), 16.76%(31/185) and 6.49%(12/185) respectively. The above values were significantly higher than those in low-level group 200(100-400) ml, 2.00 (2.00-3.00) U, (14.69±4.68) mmHg, 2.00(2.00-3.00) day, 3.53(2.34-6.12) hour, 14.69%(72/490), 11.02%(54/490) and 1.43%(7/490) respectively. The inter-group differences were statistically significant ( P<0.001, P=0.014, P=0.015, P=0.037, P=0.043, P=0.011, P=0.045 & P<0.001). The incidence of early postoperative acute cellular rejection was significantly lower in high-level group than that in low-level group [11.89%(22/185) vs 22.86%(112/490)]. The inter-group difference was statistically significant ( P=0.01). The 1/3-month cumulative survival rates of patient/graft were 94.6%, 94.1% and 92.4%, 91.4% in high-level group versus 99.2%, 98.6% and 99.0%, 98.4% in low-level group. There were significant inter-group differences ( P=0, P<0.000 1). With a rising level of lactate at 12 h postoperatively, risk of early graft loss and early recipient mortality spiked markedly ( P<0.05). Conclusions:Serum lactate level post-operation is a valid predictor of early prognosis after LT in children.

Methods: By using the stratified random cluster sampling method, 555 093 children and adolescents were selected from 12 professional institutions in league cities of the whole region for remote vision examination and refractive examination. The refraction test was carried out under the condition of non-Ciliary muscle paralysis using a desktop automatic computer optometer. Chi-squared test and multivariate Logistic regression were used to analyze the myopia status of children and adolescents and its influencing factors. Results: From 2019 to 2021, the myopia rate of children and adolescents was 53.30%, 58.65% and 54.82%, respectively, the difference was statistically significant ( χ 2=991.70, P <0.01). The overall female myopia rate(58.82%) was higher than that of male (51.52%), and the differece was statistical significant ( χ 2=3 295.66, P <0.05). The myopia rates of boys and girls by year were 49.44% and 57.30%, 54.76% and 62.60%, 51.23% and 57.62%, respectively, and the differences were statistically significant ( χ 2=1 197.02, 922.31, 1 172.09, P <0.01). The overall myopia rate of urban students (59.42%) was higher than that of suburban counties (53.61%), and the difference was statistically significant ( χ 2=1 565.03, P <0.05). The myopia rates of children and adolescentss in urban and suburban counties were 59.20% and 50.79%, 60.26% and 57.88%, 58.95% and 53.36%, and the differences were statistically significant ( χ 2=1 150.80, 74.10, 529.25, P <0.01). The children and adolescents of learning stages were of statistical significance ( χ 2=92 402.39, P <0.05), and the overall myopia rate of senior school students was the highest, accounting for 83.57%. The difference of overall myopia rates of different age groups was of statistical significance ( χ 2=121 881.67, P <0.05), and the students in age group of 17 ranked the first (83.32%), those in age group of 5 ranked the last(15.52%). Conclusion From 2019 to 2021, the myopia rate of children and adolescents in the Inner Mongolia Autonomous Region increase first and then decrease, and the myopia rate in 2020 and 2021 is higher than that in 2019. The high incidence and low age of myopia are intensifying. The prevention and controlling of myopia among children and adolescents should be strengthened, so as to reduce the occurance of myopia.

Objective:To investigate the effects of Chinese herbal decoction on traditional Chinese medicine syndrome, menstrual cycle and sex hormone levels in amenorrhea patients with polycystic ovary syndrome.Methods:A total of 124 amenorrhea patients with polycystic ovary syndrome who received treatment in The First People's Hospital of Lianyungang, China between December 2016 and December 2018 were included in this study. They were randomly assigned to receive either oral metformin hydrochloride and clomiphene citrate (control group, n = 62) or oral metformin hydrochloride and clomiphene citrate combined with Chinese herbal decoction (observation group, n = 62). Clinical effective rate and remission of traditional Chinese medicine syndrome were compared between control and observation groups. After treatment, recovery of menstrual cycle, ovulation rate, change of sex hormone level relative to before treatment, and the incidence of adverse reactions were determined in each group. Results:Total clinical effective rate in the observation group was significantly higher than that in the control group [96.77% (60/62) vs. 77.42% (48/62), χ2 = 12.817, P < 0.001]. Total effective rate in term of TCM syndrome in the control group was significantly higher than that in the observation group [83.87% (52/62) vs. 43.55% (27/62), χ2 = 21.800, P < 0.001]. After treatment, serum luteinizing hormone, free testosterone, luteinizing hormone / follicle stimulating hormone, estradiol, follicle stimulating hormone levels in the observation group were (4.28 ± 2.04) U/L, (1.93 ± 0.07) nmol/L, (3.17 ± 1.07), (240.32 ± 30.26) pmol/L, (3.17 ± 1.07) U/L, respectively, which were significantly lower than those in the control group [(6.45 ± 2.11) U/L, (3.27 ± 0.07) nmol/L, (5.73 ± 2.46), (300.32 ± 31.26) pmol/L, (5.12 ± 1.07) U/L), t = 5.822, 106.583, 7.514, 10.859, 10.147, all P < 0.001]. Ovulation rate in the observation group was significantly higher than that in the control group [80.65% (50/62) vs. 51.61% (32/62), χ2 = 11.666, P = 0.001]. Periodic ovulation rate in the observation group was significantly higher than that in the control group [91.94% (57/62) vs. 35.48% (22/62), χ2 = 14.528, P < 0.001]. In the observation group, the proportion of patients having edema, gastrointestinal reaction, vomiting, and diarrhea was 4.84% (3/62), 6.45% (4/62), 11.29% (7/62) and 11.29% (7/62), respectively, and they were 9.68% (6/62), 12.90% (8/62), 19.35% (12/62) and 25.80% (16/62)], respectively in the control group (all P < 0.05). Conclusion:Chinese herbal decoction can help regulate the hormone balance in amenorrhea patients with polycystic ovary syndrome, promote ovulation, eliminate amenorrhea, increase the curative effects on traditional Chinese medicine syndrome, and increase the rate of menstrual cycle recovery.

Objective:To explore the efficacy of reduced left lateral segment graft during pediatric living donor liver transplantation.Methods:From January 2014 to December 2019, 67 children aged under 1 year underwent living donor liver transplantation with reduced left lateral segment graft (RLLS group). Clinical data were analyzed retrospectively and compared with those of left lateral segmentgraft living donor liver transplantation (LLS group). The differences in basic profiles, postoperative complications and postoperative patient/graft survival rate were compared.They were divided into two groups according to whether graft/recipient weight ratio (GRWR) was more than 4%.And major postoperative complications and graft/recipient survival rates were compared.Results:Age, height and weight of recipients were significantly lower in RLLS group than those in control group ( P<0.05). However, donor weight, donor body mass index (BMI), estimated graft volume and proportion of fatty liver from donor were significantly higher than those in control group ( P<0.05). Operative duration, intraoperative blood loss and erythrocyte transfusion were significantly higher than those in control group ( P<0.05). No significant inter-group differences existed in average postoperative hospital stay, intensive care unit (ICU) stay duration or postoperative ventilator use time ( P>0.05); no significant inter-group difference existed in the incidence of such major surgical complications as hepatic artery thrombosis, portal vein stenosis and bile duct complications ( P>0.05). The 1/3-year cumulative survival rates of postoperative patients and grafts were 92.5%, 91.2% and 92.5%, 91.2% in RLLS group and 96.3%, 95.3% and 95.9%, 95.1% in LLS group respectively.There was no significant inter-group difference ( P<0.05). The rate of postoperative hepatic vein stenosis was significantly higher in GRWR>4% group than that in control group ( P<0.05). Conclusions:Due to a rapid progress of technology, living donor liver transplantation has achieved satisfactory outcomes in children with reduced left lateral segment graft.Whether or not performing reduction surgery should be judged comprehensively according to the matching of donors and recipients and blood flow of liver during operations.And GRWR>4% is not an implementation criterion.

Objective:To explore the influence of prognostic nutritional index (PNI) and controlling nutritional status (CONUT) on the prognosis of patients with multiple myeloma.Methods:Data of 157 patients with multiple myeloma (MM) at the affiliated hospital of Xuzhou medical university from January 2014 to December 2018 were retrospectively evaluated. The operating characteristic (ROC) curve analysis was adopted as the optimal cut-off point. PNI and CONUT were grouped based on the cut-off points of 44.45 and 3.5, respectively, and the differences between age, gender, serum calcium, β 2-microglobulin, serum creatinine, lactate dehydrogenase, and hemoglobin were analyzed. The prognostic factors were analyzed via univariate and Cox multivariate regression analyses. Results:The level of PNI and CONUT is the influencing factor of OS time. The univariate analysis revealed that age, LDH, plasma cell ratio, β 2-microglobulin, ISS stage, PNI, and CONUT were the risk factors for the prognosis of patients with MM. The multivariate analysis revealed that age ( HR=1.636, 95% CI 1.014-2.640) , plasma cell ratio ( HR=1.953, 95% CI 1.232-3.096) , and PNI ( HR=0.513, 95% CI 0.287-0.917) were the independent prognostic risk factors of patients with MM. Conclusion:Low PNI in patients with MM indicates a poor prognosis, which is an independent prognosis risk factor.
