BACKGROUND: Parental myopia is an important risk factor for myopia in Chinese children and adolescents. This study aimed to assess the influence of parental myopia and the severity of myopia on offspring and to evaluate whether adopting healthy lifestyles can mitigate the effects of parental myopia on offspring. METHODS: This cross-sectional study analyzed data from children and adolescents aged 6-17 years with complete vision assessments and parental history of myopia from six provinces in China during 2013-2014. Parental demographic information, children's outdoor activity time, sleep time, and sedentary time were collected via questionnaire. Parental myopia was classified as no myopia, paternal myopia, maternal myopia, and both. The offspring were categorized into 10 groups based on parental myopia prescription. Associations of the above factors with myopia in children and adolescents were evaluated by logistic regression analysis. RESULTS: Among 40,864 children and adolescents (50.3% boys and 49.7% girls), 22,537 (55.2%) were diagnosed with myopia. In comparison to offspring devoid of parental myopia, children with one parent affected by myopia exhibited odds ratio (OR) of 1.75 (95% confidence interval [CI]: 1.62-1.88) for myopia, while those with both parents affected showed OR of 2.27 (95% CI: 2.02-2.55) after adjusted for lifestyle factors. The likelihood of myopia in offspring increased with increasing severity of parental myopia, with a 3.08-fold increase in risk observed when both parents presented high myopia. Nonetheless, children adhering to two or more healthy lifestyle factors demonstrated a diminished risk of myopia compared with those with fewer than two lifestyle factors, especially among offspring of non-myopic or mildly myopic parents. CONCLUSIONS Parental myopia has a dose-dependent association with their offspring. Healthy lifestyles may reduce the impact of parental factors on myopia in offspring. The observed associations suggest that although the genetic burden of parental myopia cannot be ignored, healthy lifestyles and nurturing are also very important.

Objective To investigate the expression levels and the clinical significance of upstream tran-scription factor 2(USF2)and ubiquitin-specific protease 10(USP10)in peripheral blood of patients with sep-sis combined with acute kidney injury(AKI).Methods A total of 259 patients with sepsis were selected from Jilin Provincial People's Hospital from January 2018 to December 2022.Patients were divided into AKI group(107 cases)and non AKI(NAKI)group(152 cases)according to whether they had AKI or not.General clini-cal data were collected and the expression levels of USF2 and USP10 in peripheral blood were detected.Pear-son analysis was used to investigate the correlation between USF2,USP10,and renal function.Binary Logistic regression analysis was used to investigate the factors influencing sepsis patients with AKI.Receiver operating characteristic(ROC)curve was drown to analyze the value of USF2 and USP10 in diagnosing AKI in patients with sepsis.Results The expression level of serum USF2 in AKI group was higher than that in NAKI group,and the difference was statistically significant(P＜0.05),while the serum USP10 expression level in AKI group was lower than that in NAKI group,and the difference was statistically significant(P＜0.05).In AKI group,USF2 expression was positively correlated with urea nitrogen(BUN),serum creatinine(Scr)and Cys-tatin C(CysC)(P＜0.05),while USP10 expression was negatively correlated with BUN,Scr and CysC(P＜0.05).High sequential organ failure assessment(SOFA)score,septic shock and high expression of USF2 were risk factors for AKI in sepsis patients(P＜0.05),and high expression of USP10 was protective factor(P＜0.05).The area under the curve(AUC)of single detection of USF2 and USP10 for diagnosing AKI in patients with sepsis was 0.742(95％CI:0.676-0.808)and 0.781(95％CI:0.724-0.839),respectively.The AUC of the combination of USF2 and USP10 for diagnosing AKI in patients with sepsis was 0.907(95％CI:0.865-0.948),which was higher than that of single detection(P＜0.05).Conclusion Increased expression of USF2 and decreased expression of USP10 in peripheral blood of patients with sepsis are associated with in-creased risk of AKI and decreased renal function.

Objective:To explore the locations of the lumbosacral nerve roots by use of the magnetic stimulation.Methods:Thirty healthy subjects were studied. The projections of the right L 2 to S 1 intervertebral foramina on their body surfaces were determined manually with ultrasound assistance. Magnetic stimulation was applied to different nerve root segments to induce compound muscle action potentials (CMAP) in the vastus medialis, tibialis anterior, and gastrocnemius muscles of the lower limbs. The changes in latency, amplitude, and motor threshold were observed. Results:Magnetic stimulation on the L 2-L 3 segment resulted in a significant direct excitation of the vastus medialis. That on the L 5-S 1 segment evoked a significant direct excitatory effect on the tibialis anterior and gastrocnemius, with a motor threshold below 40%, an amplitude exceeding 1mV, and many effective responses. However, during the magnetic stimulation on the L 4 segment, the amplitude of the vastus medialis was above 1mV, with no significant differences in the number of effective responses among the muscle groups. Moreover, there was a stepwise change in the latency of effective muscle responses to magnetic stimulation at different segments. The CMAP latencies of 12+ ms for the tibialis anterior and 13+ ms for the gastrocnemius indicated activation of the L 5 and L 4 nerve roots, respectively, while those of 6+ ms, 7+ ms, and 8+ ms for the vastus medialis suggested activation of the L 4, L 3, and L 2 nerve roots, respectively. Conclusions:Based on the responses (CMAP latency, amplitude and motor threshold) of the vastus medialis, tibialis anterior and gastrocnemius to magnetic stimulation at different L 2 to S 1 segments, the spinal nerve root segments responsible for innervation can be inferred.

Objective:To establish a Nomogram model for predicting intraoperative pressure injury in adult patients undergoing allograft orthotopic liver transplantation and to test its effectiveness.Methods:Using the convenient sampling method, a total of 257 patients who underwent allograft orthotopic liver transplantation in Beijing Chaoyang Hospital Affiliated to Capital Medical University from May 2015 to May 2021 were selected as the research objects for retrospective analysis. Multivariate Logistic regression was used to analyze the risk factors of intraoperative pressure injury in liver transplantation patients and a Nomogram model was established. The receiver operating characteristic (ROC) curve was used to verify the accuracy of the model.Results:Among the 257 patients, 39 had intraoperative pressure injury, with an incidence of 15.18% (39/257). Univariate analysis showed that high body mass index, low serum albumin before surgery, use of norepinephrine, epinephrine, large amount of blood loss and blood transfusion, intraoperative compression site immersion, long operation time and high score of end-stage liver disease model were risk factors for intraoperative pressure injury in patients undergoing liver transplantation ( P<0.05). Multivariate Logistic regression analysis showed that low level of preoperative serum albumin, norepinephrine use, intraoperative compression site immersion, long operation time and end-stage liver disease model score greater than 16 points were independent risk factors for intraoperative stress injury in transplant patients ( P<0.05). Based on this, the Nomogram model was established. The C- index value was 0.882, the area under ROC curve was 0.882 and the sensitivity and specificity were respectively 0.839 and 0.821. Conclusions:This Nomogram model established in this study can accurately predict the risk of intraoperative pressure injury in patients undergoing liver transplantation. This prediction method is convenient and intuitive, which can guide clinical nurses to quickly, effectively and accurately judge the risk of intraoperative stress injury in patients undergoing liver transplantation.

A 49-year-old male patient with type 2 diabetes mellitus and diabetic nephropathy received long term use of retaglinide thrice daily orally, 1 mg in the morning, 2 mg in the afternoon and 1 mg in the evening. Because of the sudden acute cerebral infarction, clopidogrel was added, on the 4th day of the medication, the fasting blood glucose in the patient decreased to 2.6 mmol/L. It was considered that the interaction of clopidogrel and repaglinide caused the increase of repaglinide plasma concentration, which resulted in severe hypoglycemia in the patient. Clinical pharmacist suggested stopping repaglinide and using insulin. The physician reduced the dosage of repaglinide to twice daily, 1 mg in the morning and 0.5 mg in the afternoon, and after 3 days the patient′s fasting blood glucose fluctuated between 4.0 and 4.5 mmol/L. Since the patient had diabetes nephropathy and renal insufficiency, which might increase the risk of hypoglycemia, repaglinide was stopped, and insulin glutamine 3 U was injected subcutaneously before meals, at the same time blood glucose was closely monitored. Fasting blood glucose fluctuated between 4.9 and 5.4 mmol/L after insulin treatment.

Objective: To investigate the effect of gross motor skills on physical activity of children aged 3-6 years, and to provide basis for children’s health behavior intervention. Methods: A total of 332 young children in Shanghai Xiangyin kindergarten were selected as survey objects. The development of gross movements of young children was measured by TGMD-2. Caregivers reported children’s physical activity using the International Physical Activity Questionnaire (IPAQ-SF). Results: The development level of gross movements of children aged 3-6 in Shanghai was relatively low(54.76±13.86). The physical activity of children was mainly light-intensity physical activity, and the daily moderate-to-vigorous intensity physical activity time was (58.62±52.73) minutes every day. Locomotor skills had the greatest effect on children’s VPA (β=0.19) and TPA(β=0.12), with a contribution rate of 3.3% and 1.1%, respectively; Object control skills has the greatest effect on children’s MVPA (β=0.17) and MPA (β=0.12) had the largest effect(P<0.05), with contribution rates of 2.5% and 1.2%, respectively. The relationship between gross motor skills and physical activity had nothing to do with gender and age. Conclusion Children’s gross motor skills in the 3-6 year-old population should be improved and may be an effective way to promote physical activity.

The important role of intestinal microorganisms in human health has been widely confirmed. At present, most of the studies on intestinal microorganisms are based on amplification of the V3-V4 region of bacterial 16S rRNA gene, and little attention has been paid to archaea. In this study, a primer set which can amplify 16S rRNA gene of both bacteria and archaea at the same time was used. By comparing the community changes before and after probiotics intake, it showed that this primer set is suitable for analyzing the changes of human intestinal bacteria and archaea communities. The fecal samples of volunteers were collected, and the amplification and high-throughput sequencing were carried out by using bacterial primer set (B primer) and bacterial and archaeal universal primer (AB primer); several commonly used rRNA databases were used to determine the amplification ability of the primer set to bacteria and archaea. The results showed that AB primer could display the bacterial community amplified by B primer, and could obtain the sequence of common methanogenic archaea in intestinal tract. AB primer set can analyze the bacteria and archaea in the intestinal tract at the same time by only one amplification and sequencing, which can show the structure of intestinal microbial community more comprehensively, which is suitable for the research of intestinal microorganisms.

Objective To investigate the influence factors of serum Angptl 2 levels is to explore the relationship between serum Angptl 2 and carotid atherosclerosis (CAS) in patients with type 2 diabetes mellitus (T2DM). Methods 114 cases of T2DM in clinic were selected.According to the results of color doppler ultrasonography,the patients were divided into T2DM with CAS group(T2DM + CAS,n=58)and simple T2DM group(n= 56).56 healthy subjects were selected as normal control (NC)group during the same period.ELISA method was used to detect the level of serum Angptl 2. Results Serum Angptl 2 levels were significantly higher in T2DM + CAS group and T2DM group than in NC group [(69.83 ± 12.07) vs (42.93 ± 10.44)vs (24.26 ± 8.78)ng/ml,P< 0.01].Correlation analysis showed that serum Angptl 2 was positively correlated with age,BMI,SBP,DBP,TC,TG,LDL-C,FPG and HbA1c in T2DM patients (r=0.574,0.325,0.528,0.308,0.396,0.387,0.295,0.536 and 0.601,respectively,P<0.01),and negatively correlated with HDL-C and FIns in T2DM patients (r= -0.248,-0.352,P<0.01).Similarly,multiple regression analysis showed that FIns,and HbA1c were the independent factors of serum Angptl 2 (β= -2.186,2.680,P<0.01). Conclusion Serum Angptl 2 level is closely related to obesity,blood pressure,blood glucose,blood lipid and insulin.Serum Angptl 2 may play an important role in the development of T2DM and carotid atherosclerosis.
