Diabetic peripheral neuropathy （DPN） is one of the common complications of diabetes. The disease has a long course with nerve pain and other symptoms， seriously affecting the quality of life of patients. DPN is related to high glucose in vivo， inflammation， oxidative stress， apoptosis， and autophagy， involving phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt）， Janus kinase （JAK）/signal transducer and activator of transcription （STAT）， nuclear factor-κB （NF-κB）， mitogen-activated protein kinase （MAPK）， and other signaling pathways. At present， the treatment of DPN mainly focuses on symptomatic treatments such as blood glucose control and neurotrophic therapy， but the effect is not ideal. Therefore， it is particularly important to select a reasonable and effective drug to prevent and treat DPN. In recent years， Chinese medicine has played an important role in the treatment of DPN. Many studies have explored the mechanism of Chinese medicine in the treatment of DPN， and it has been found that some Chinese medicine monomers and compounds can regulate signaling pathways to prevent and treat DPN. This paper reviewed the research results of signaling pathways involved in DPN and the regulation of related pathways by Chinese medicine， aiming to provide references for the clinical treatment of DPN.

Methods:Two thousand standard sections images werre collected from 2 000 clinical retrospective pediatric hip ultrasound videos from January 2019 to January 2021. All standard sections were annotated by the annotation team through the self-designed software based on Python 3.6 environment for image cross-media data annotation and manual review standardization process with unified standards. Among them, 1 753 were randomly selected for training the deep learning system, and the remaining 247 were used for testing the system. Further, 200 standard sections were randomly selected from the test set, and 8 clinicians independently completed the film reading annotation. The 8 independent results were then compared with the AI results.Results:The testing set consists of 247 patients. Compared with the clinician's measurements, the area under the receiver operating characteristic curve (AUC) of diagnosing hip joint maturity was 0.865, the sensitivity was 76.19%, and the specificity was 96.9%. The AUC of AI system interpretation under Graf detailed typing was 0.575, the sensitivity was 25.90%, the specificity was 89.10%. The 95% LoA of α-angle determined by Bland-Altman method, of -4.7051° to 6.5948° ( Bias -0.94, P<0.001), compared with clinicians' measurements. The 95% LoA of β-angle, of -7.7191 to 6.8777 ( Bias -0.42, P=0.077). Compared with those from 8 clinicians, the results of AI system interpretation were more stable, and the β-angle effect was more prominent. Conclusion:The AI system can quickly and accurately measure the Graf correlation index of standard DDH ultrasonic standard diagnosis plane.

Cow′s milk protein allergy (CMPA) is one of the most common presentations of food allergy seen in early childhood.It is an abnormal immune response caused by cow′s milk protein.CMPA can be clinically subdivided into either immediate-onset IgE mediated or delayed onset non-IgE mediated, or both.At present, concerns regarding the early and timely diagnosis of CMPA have been high-lighted over the years and there are many expert consensus on CMPA in China, but these consensus did not distinguish IgE mediated or non-IgE mediated CMPA.In view of the obvious clinical differences between the two type of CMPA and non-IgE mediated CMPA is more common in infancy, experts focus on pediatric gastroenterology, allergy/immunology, dermatology, nutrition and child healthcare convened by the Allergy Prevention and Control Professional Committee of Chinese Preventive Medicine Association present this guideline to help practitioners in primary care settings to early recognize and make suitable management of non-IgE mediated CMPA in China.The guideline incorporates the cutting-edge international guidance and the actual situation of Chinese children describing in detail the types, clinical features, diagnosis and nutritional intervention of non-IgE mediated CMPA.There are 42 recommendations in 7 categories in total referring to the common questions related to non-IgE mediated CMPA.

Objective:To investigate the application value of Hisense computer-assisted surgery system (CAS) three-dimensional reconstruction in the precision treatment of pediatric liver tumors.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 82 children with liver tumors who were admitted to Affiliated Hospital of Qingdao University from January 2013 to September 2021 were collected. There were 39 males and 43 females, aged 13(19)months. Children underwent upper abdominal dynamic enhanced computed tomography (CT) examination, and three-dimensional reconstruction was performed on CT images of arterial, equili-brium and venous phases with Hisense CAS. Surgical feasibility and scheme were evaluated and conducted based on the results of upper abdominal dynamic enhanced CT examination, and then revised according to three-dimensional reconstruction results of Hisense CAS. Observation indicators: (1) comparison of surgical scheme between two-dimensional enhanced CT images and three-dimensional reconstruction results of Hisense CAS; (2) intraoperative and postoperative situations; (3) follow-up. Follow-up was conducted by outpatient examination to detect postoperative compli-cations and residual liver compensation up to November 2021. Measurement data with normal distribution were represented as Mean± SD. Measurement data with skewed distribution were represented as M(IQR) or M(range). Count data were described as absolute numbers or percentages. Results:(1) Comparison of surgical scheme between two-dimensional CT images and three-dimensional reconstruction results of Hisense CAS. ① Based on the two-dimensional CT images, 42 cases of 82 children could undergo one-stage resection and 40 children could not. However, based on the three-dimensional reconstruction results of Hisense CAS, 48 cases of 82 children could undergo one-stage resection and 34 children could not. There were 6 children with one-stage resection feasibility based on the three-dimensional reconstruction results of Hisense CAS rather than the two-dimensional CT images. For the 34 children undergoing chemotherapy firstly, 31 cases had surgical feasibility after chemotherapy based on the two-dimensional CT images and 3 cases could not undergo surgery because of unapparent tumor regression or tumor surrounding impor-tant vessels. However, the 34 children had surgical feasibility after chemotherapy based on the three-dimensional reconstruction results of Hisense CAS. The revision rate of surgical feasibility was 11.0%(9/82) for the 82 children. ② Based on the two-dimensional CT images, 15 cases of 82 children underwent liver left lobectomy, 21 cases underwent liver right lobectomy, 7 cases underwent mesohepatectomy, 13 cases underwent extended left hemihepatectomy, 23 cases underwent extended right hemihepatectomy, 3 cases underwent segmental hepatectomy. However, based on the three-dimensional reconstruction results of Hisense CAS, 20 cases of 82 children underwent liver left lobectomy, 29 cases underwent liver right lobectomy, 7 cases underwent mesohepatectomy, 7 cases underwent extended left hemihepatectomy, 14 cases underwent extended right hemihepatectomy, 5 cases underwent segmental hepatectomy. The revision rate of surgical scheme was 36.6%(30/82) for the 82 children. (2) Intraoperative and postoperative situations. The operation time, volume of intraoperative blood loss, duration of postoperative hospital stay of the 82 children were (182±18)minutes, 20(10)mL, (10.2±1.9)days, respectively. (3) Follow-up. All the 82 children were followed up for 10 (range, 2?18)months. There was no obvious complication occurred to the 82 children after surgery, and the residual liver can satisfy the liver compensation of body. All the children survived well.Conclusion:Three-dimensional reconstruction of Hisense CAS is conducive to judging the surgical feasibility and formulation of accurate surgical plan of children with liver tumors.

Objective:To investigate the clinical efficacy of Kirschner wire reconstruction of periosteal hinge combined with "rolling pin" technique assisting closed reduction and percutaneous Kirschner wire fixation versus closed reduction and percutaneous Kirschner wire fixation in the treatment of flexion-radial deviated supracondylar fracture of the humerus in children.Methods:A retrospective cohort study was used to analyze the clinical data of 85 patients with flexion-radial deviated supracondylar fracture of the humerus treated in Anhui Provincial Children ′s Hospital from January 2017 to December 2021, including 53 males and 32 females; aged 4-14 years [(7.4±2.7)years]. There were 49 patients treated by Kirschner wire reconstruction of periosteal hinge combined with "rolling pin" technique assisting closed reduction and percutaneous Kirschner wire fixation (study group) and 36 patients by closed reduction and percutaneous Kirschner wire fixation (control group). The operation time, number of intraoperative fluoroscopy, rate of incision after failure of closed reduction (hereinafter referred to as rate of incision), fracture healing time, and elbow joint function by Flynn score at the last follow-up were compared between the two groups. Complications were observed at 2 months after operation, such as infection and irritation of the Kirschner pin tail. Results:All patients were followed up for 2-12 months [(6.2±2.2)months]. The operation time and number of intraoperative fluoroscopy was (62.4±21.4)minutes and (34.8±7.1)times in control group, significantly longer or more than (31.2±14.1)minutes and (22.5±5.1) times in study group ( P<0.05 or 0.01). The incision rate was 17% in control group, but was 0 in study group ( P<0.01). The fracture healing time had no significant difference between control group and study group [(4.5±0.8)weeks vs. (4.6±0.6)weeks] ( P>0.05). According to Flynn score at the last follow-up, the excellent and good rate of elbow function was 89% in control group (excellent in 26 patients, good in 6, fair in 4, poor in none), not significantly different from 94% in study group (excellent in 41 patients, good in 5, fair in 3, poor in none) ( P>0.05). There was no infection or irritation of the Kirschner pin tail in the two groups at 2 months after operation. Conclusion:Kirschner wire reconstruction of periosteal hinge combined with "rolling pin" technique assisting closed reduction and percutaneous Kirschner wire fixation has similar effect to closed reduction and percutaneous Kirschner wire fixation in the treatment of flexion-radial deviated supracondylar fracture of the humerus, but the former has relatively shorter operation time, less intraoperative fluoroscopy and lower incision rate.

OBJECTIVE: To determine the carrier rate of deafness-related genetic variants among 53 873 newborns from Zhengzhou. METHODS: Heel blood samples of the newborns were collected with informed consent from the parents, and 15 loci of 4 genes related to congenital deafness were detected by microarray. RESULTS: In total 2770 newborns were found to carry deafness-related variants, with a carrier rate of 5.142%. 1325 newborns (2.459%) were found to carry heterozygous variants of the GJB2 gene, 1071 (1.988%) were found with SLC26A4 gene variants, 205 were found with GJB3 gene variants (0.381%), and 120 were found with 12S rRNA variants (0.223%). Five newborns have carried homozygous GJB2 variants, two have carried homozygous SLC26A4 variants, five have carried compound heterozygous GJB2 variants, and four have carried compound heterozygous SLC26A4 variants. 33 neonates have carried heterozygous variants of two genes at the same time. CONCLUSION The carrier rate of deafness-related variants in Zhengzhou, in a declining order, is for GJB2, SLC26A4, GJB3 and 12S rRNA. The common variants included GJB2 235delC and SLC26A4 IVS7-2A>G, which are similar to other regions in China. To carry out genetic screening of neonatal deafness can help to identify congenital, delayed and drug-induced deafness, and initiate treatment and follow-up as early as possible.

Objective: To explore the clinical value of plasma heme oxygenase 1(HO-1) in the development of non-alcoholic fatty liver disease(NAFLD). Methods: Patients with NAFLD were selected from the Physical examination center and the Department of Traditional and Western Medical Hepatology of Third Hospital of Hebei Medical University. A combination of ultrasound and liver elastography was used to screen NAFLD patients and healthy persons. General clinical characteristics, peripheral blood cell count and liver biochemical test results were collected synchronously, plasma samples were retained, and plasma HO-1 level was detected by enzyme-linked immunosorbent assay. SPSS21.0 statistical software was used for statistical analysis, multivariate logistic regression analyses was used to analyse the independent risk factors affecting the incidence and progression of NAFLD. The diagnostic efficacy of indicators related to development of NAFLD was assessed by the receiver operating characteristic curve(ROC). Results: A total of 328 patients with NAFLD and 113 healthy controls were included. According to the liver biochemical results, the NAFLD group was divided into 148 patients with normal liver enzymes and 180 patients with abnormal liver enzymes. The level of HO-1 in the three groups was 9.09 ± 2.19, 14.38 ± 2.63, 17.00 ± 3.30 ng/ml, and was increased respectively of healthy controls, patients with normal liver enzymes and patients with abnormal liver enzymes. Analyzing plasma HO-1 levels of components associated with metabolic disorders suggests that components without metabolic syndrome(9.83 ± 3.21) < components with 1 metabolic syndrome(13.59 ± 3.72) < components with 2 or more metabolic syndrome(16.09 ± 3.41), P < 0.001. The results of HO-1 level stratification analysis showed that WBC, ALT, AST, GGT, TG increased as HO-1 level increased, and the pairwise difference was statistically significant (P < 0.001). The WBC count of NAFLD is significantly higher than healthy group(6.79 ± 1.62 vs 5.68 ± 1.36, P < 0.001). The univariate and multivariate regression analyses of all the subjects showed that HO-1, TG and BMI were prognostic factors for the occurrence of NAFLD and HO-1, TC, GLU were prognostic factors for the progression of NAFLD, P < 0.05. The ROC analysis showed that HO-1 was reliable markers for predicting the occurrence and progression of NALFD, the sensitivity and specificity were respectively 85.10%, 92.90% and 38.33%, 95.27%. Conclusion Plasma HO-1 can predict the occurrence and progression of NAFLD and is expected to be a novel molecular diagnostic marker for NAFLD and NASH.

Objective To explore the prognostic values of telomerase reverse transcriptase promoter (TERTp) mutation and 1p/19q co-deletion in newly-diagnosed O6-methylguanine-DNA methyltransferase (MGMT) promoter un-methylated/isocitrate dehydrogenase (IDH) wild-type glioblastoma multiform (GBM). Methods A total of 82 patients pathologically newly-diagnosed MGMT promoter un-methylated/IDH wild-type GBM, admitted to our hospitals from March 2016 to November 2018, were included in this study. TERTp mutations (TERTp wild-type and TERTp mutation [C228 mutation and C250 mutation]) in GBM specimens were detected by PCR sequencing, 1p/19q co-deletion in GBM specimens was detected by fluorescence in situ hybridization (FISH), and clinical data, adverse reactions and prognoses of patients with different molecular typing were compared. Results There were 33 patients in the TERTp wild type group with mean age of 48 years, and 49 patients in the TERTp mutation group with mean age of 59 years; the difference of age was significant (P<0.05); there were no statistical differences in gender distribution, Karnofsky performance status (KPS) scores, tumor sites and surgical resection degrees between the two groups (P>0.05). There were 8 patients with 1p/19q co-deletion and 74 patients without 1p/19q co-deletion; no significant differences in above clinical parameters were noted between the two groups. There were no statistically significant differences in the incidences of bone marrow suppression, digestive tract response and fatigue, disease progression rate, or survival rate between patients from TERTp wild type group and TERTp mutation group, and between patients with 1p/19q co-deletion and patients without 1p/19q co-deletion (P>0.05). No significant differences in above clinical parameters, disease progression rate, and survival rate were noted between patients with C228 mutation and C250 mutation (P>0.05). Conclusion TERTp typing and 1p/19q co-deletion status do not have prognostic value in newly-diagnosed MGMT un-methylated/IDH wild-type GBM patients; patients with TERTp mutations have older age than wild-type patients; patients with C250 mutation trend to have higher survival rate than those with C228 mutation.
