ObjectiveTo explore the effect of precocious puberty on glucose metabolism and lipid metabolism in female rats. MethodsSixty two-day-old female rats were randomly divided into 2 groups. When aged 5 days， the precocious puberty group and normal group were given a single subcutaneous injection of danazol and solvent soybean oil respectively. The vaginal opening of rats was monitored from their 21 days of age. After 12 hours of fasting， all successful modeling rats were randomly executed within 3 days after vaginal opening， when aged 7 and 12 weeks. Then we measured the rats’ body weight and length， determined the concentrations of glucose， insulin， blood lipids， estradiol， leptin and adiponectin with enzyme-linked immunosorbent assay and observed the pathological changes of perirenal fat， uterus and ovary. ResultsFor body weight and length， rats in the precocious puberty group were smaller than those in the normal group within 3 days after vaginal opening， but which did not affect their subsequent growth and development， and there was no significant difference between the two groups at 7 and 12 weeks of age. Within 3 days after vaginal opening， insulin levels had significant difference between the two groups （P = 0.001）， the precocious group showed hyperinsulinemia and increased number of perirenal adipocytes. At three execution times， no significant difference was noted in estradiol， leptin and adiponectin levels between the two groups. The same was true in the ratios of ovary or uterus to body weight between the two groups. ConclusionsPrecocious puberty makes earlier onset of pubertal development and allows body maladaptation to the sudden changes of the internal environment. However， the changes due to precocious puberty are temporary and reversible， and they may become normal in adulthood.

Objective To explore potential genes associated with the pathogenesis of hypospadias using weighted Gene co-expression network analysis(WGCNA).Methods The WGCNA algorithm was used to process the hypospadias-related dataset GSE35034,and then a gene co-expression weight network was constructed to screen the modules with the highest correlation with hypospadias,and the genes in the modules were enriched and detected by gene ontology(GO),Kyoto Encyclopedia of Genes and Genomes(KEGG).Differential analysis was also performed to screen out differential genes.The differential genes were imported into the String database.Using Cytoscape software,the hub genes in the network were identified.The results screened by the above three methods were combined and analyzed,and the core genes in the intersection set were screened.Using the external dataset GSE121712,the core genes were verified by mRNA expression changes and subject work characterization receiver operating characteristic(ROC)curve diagnosis.Results Fifteen co-expression modules were obtained based on the WGCNA method.Ninety-three common differential genes meeting the conditions were obtained by differential analysis.Ten core genes were finally obtained by Cytoscape software analysis.Finally MEbrown module,differential genes and the 10 core genes yielded a total of 2 intersecting genes:FBXL16 and SYNDIG1.ROC curves verified that the intersecting genes were differentially expressed in patients with hypospadias versus normal subjects.Conclusion In this study,two key genes with significant correlation with hypospadias were obtained by WGCNA,which may be used for the early diagnosis and treatment of hypospadias after further study.

【Objective】 To develop a quick and accurate crossmatching test technology without the power equipment and additional reagents before blood transfusion, so as to improve the timeliness and safety of blood transfusion treatment in sudden situations as war or natural disasters. 【Methods】 The irregular antibodies quickly promote coagulants (QPC) were used as the reaction medium reagent. The 200 μL QPC were wrapped in the bursts bead and preset within different recess of the detection tubes. The bursts beads were squeezed with the reagent left in the well, then the blood samples were dropped in the main(recipient plasma: 200 μL, donor 3%—5% RBC: 100 μL) and secondary(donor plasma: 200 μL, recipient 3%—5% RBC: 100 μL)reaction grooves. The result interpretated by hand wrestling or 1 500 g centrifugation of 15 seconds. Meanwhile, the comparing experiments with the prior methods were implemented to evaluate the method’s reliability. 【Results】 The results of the bursting reagent, being stored at 37℃ for one week, were consistent with those of the freshly prepared cross-matching reagent, indicating that the bursting reagent was practical in the field and had good stability at normal temperature. No statistical difference between the sensitivity and the results of the microcolumn gel method was noticed by paired data t test (P>0.05). The parallel cross matching tests of 50 clinical samples were performed by microcolumn gel method and coagulant-bursting technique; the Kappa value was 0.973 2, and irregular antibodies were detected in 2 cases, with concordance rate at 100%, showing good consistency. 【Conclusion】 The improved method is simple and fast, and also safe and reliable for compatibility testing before blood transfusion, which is especially suitable for the field rescue of the wounded in wartime and sudden natural disasters, and is worthy of popularization.

Objective:To analyze the clinical efficacy of the Yuying powder combined with the Huanglian Shangqing pill for the treatment of subacute thyroiditis (SAT) with cervical anterior pain as the main complaint, as well as its impact on serum pain factors and oxidative stress levels in patients.Methods:A prospective selection of 100 SAT patients with anterior cervical pain as the main complaint admitted to the Hebei Provincial Hospital of Traditional Chinese Medicine from January 2020 to May 2022 was conducted. They were randomly divided into two groups, with 50 patients in each group. The control group was treated with sustained-release diclofenac sodium tablets, while the observation group was treated with external application of the Yuying powder and internal administration of the Huanglian Shangqing pill. After 2 weeks of continuous treatment, the analgesic efficacy and adverse drug reactions of both groups were observed. The analgesic onset time of two groups of anterior cervical pain was compared. Two simplified McGill pain questionnaires before and after treatment [the SF-MPQ scores, including Pain Rating Index (PRI), Visual Analog Scale (VAS), and Current Pain Intensity (PPI) ], were compared; the traditional Chinese Medicine Syndrome Score, Serum Pain Factors levels [ tumor necrosis factor (TNF)- α, interleukin-1 β(IL-1β), prostaglandin E 2 (PGE 2), and nitric oxide (NO) ] and oxidative stress indicators [the levels of malondialdehyde (MDA), superoxide dismutase (SOD), and glutathione peroxidase (GSH-Px) ] were also compared. Results:The total effective rate of analgesia in the observation group [98.00%(49/50)] was significantly higher than that in the control group [82.00%(41/50)] ( P<0.05). The analgesic onset time in the observation group was significantly shorter than that in the control group ( P<0.05). After treatment, the scores of various components (PRI, VAS, PPI) and traditional Chinese medicine syndrome scores in the two groups of SF-MPQ were significantly reduced compared to before treatment (all P<0.05); and the decrease was more significant in the observation group (all P<0.05). After treatment, the serum levels of TNF -α, IL-1β, PGE 2, and NO in both groups significantly decreased compared to before treatment (all P<0.05), and the levels of serum pain inducing factors in the observation group were significantly lower than those in the control group (all P<0.05). After treatment, both groups showed a significant decrease in serum MDA content (all P<0.05), and a significant increase in serum SOD and GSH-Px levels (all P<0.05); And the improvement was more significant in the observation group (all P<0.05). The incidence of adverse reactions in the observation group [4.00%(2/50)] was lower than that in the control group [16.00%(8/50)] ( P<0.05). Conclusions:The overall efficacy of external application of Yuying powder combined with oral administration of Huanglian Shangqing pill in the treatment of SAT with cervical anterior pain as the main complaint is definite, and its effect may be related to significantly downregulating the expression level of serum related pain inducing factors in patients and reducing the level of oxidative stress in the body.

Objective:To explore the predictive value of renal resistive index (RRI) joint with semiquantitative power Doppler ultrasound (PDU) score to acute kidney injury (AKI) in non-septic critically ill patients.Methods:This prospective observational study enrolled non-septic critically ill patients admitted to the Emergency Intensive Care Unit of Cangzhou Central Hospital from January 2018 to August 2019. In addition to general data, RRI and PDU scores were measured with medical ultrasonic instrument within 6 h after admission. Renal function was assessed on the 5th day in accordance with kidney disease: Improving Global Outcomes criteria. The patients who progressed to AKI stage 3 within 5 days after admission were classified into the AKI 3 group, and the rest were classified into the AKI 0-2 group. The difference of each index was compared between the two groups in non-septic critically ill patients and patients with acute heart failure (AHF). Normal distributed continuous variables were compared using independent sample t-tests, whereas Mann-Whitney U tests were used to examine the differences in variables without a normal distribution. Categorical data were compared with the Chi-square test. Receiver operator characteristic curves were plotted to examine the values of RRI, PDU score, RRI-RDU/10 (subtraction of RRI and 1/10 of PDU score), RRI/PDU (the ratio of RRI to PDU score), and RRI+PDU (the prediction probability of the combination of RRI and PDU score for AKI stage 3 obtained by logistic regression analysis) in predicting AKI 3. Delong's test was used to compare the area under the curve (AUC) between predictors. Results:A total of 110 non-septic critically ill patients (51 patients with no AKI, 21 with AKI stage 1, 11 with AKI stage 2, and 27 with AKI stage 3) were recruited. Among them, there were 63 patients with AHF (21 patients with no AKI, 15 with AKI stage 1, 7 with AKI stage 2, and 20 with AKI stage 3). Among the non-septic critically ill patients as well as its subgroup of AHF, compared with the AKI 0-2 group, acute physiology and chronic health evaluation-Ⅱ score, sequential organ failure assessment score, arterial lactate concentration, mechanical ventilation rate, proportion of vasoactive drugs, 28-day mortality, serum creatinine, RRI, RRI-RDU/10, RRI/PDU, RRI+PDU, and rate of continuous renal replacement therapy were higher in the AKI 3 group, and urine output and PDU score were lower ( all P<0.05). As for non-septic critically ill patients, RRI/PDU [AUC=0.915, 95% confidence interval ( CI): 0.846-0.959, P<0.01] and RRI+PDU (AUC=0.914, 95% CI: 0.845-0.959, P<0.01) performed best in predicting AKI 3, and the AUCs were higher than RRI (AUC=0.804, 95% CI: 0.718-0.874, P<0.01) and PDU score (AUC=0.868, 95% CI: 0.791-0.925, P<0.01). The optimal cutoff for RRI/PDU was > 0.355 (sensitivity 92.6%, specificity 81.9%, Youden index 0.745). The predictive value of RRI-RDU/10 for AKI 3 (AUC=0.899, 95% CI: 0.827-0.948, P<0.01) was also better than RRI and PDU scores, but slightly worse than RRI/PDU and RRI+PDU, with statistically difference only between RRI and RRI-RDU/10 ( P<0.05). As for patients with AHF, RRI/PDU (AUC=0.962, 95% CI: 0.880-0.994, P<0.01) and RRI+PDU (AUC=0.962, 95% CI: 0.880-0.994, P<0.01) also performed best in predicting AKI 3, and the AUCs were higher than RRI (AUC=0.845, 95% CI: 0.731-0.924, P<0.01) and PDU score (AUC=0.913, 95% CI: 0.814-0.969, P<0.01) with statistically differences (all P<0.05). The optimal cutoff for RRI/PDU was > 0.360 (sensitivity 95.0%, specificity 90.7%, Youden index 0.857). The predictive value of RRI-RDU/10 for AKI 3 (AUC=0.950, 95% CI: 0.864-0.989, P<0.01) was also better than RRI and PDU score, but slightly worse than RRI/PDU and RRI+PDU, with statistically difference only between RRI and RRI-RDU/10 ( P<0.05). Conclusions:The combination of RRI and PDU score could effectively predict AKI 3 in non-septic critically ill patients, especially in patients with AHF. The ratio of RRI to PDU score is recommended for clinical application because of its excellent predictive value for AKI and its practicability.

Objective:To evaluate the correlation between the timed up and go(TUG)test and fall risks in elderly frail patients.Methods:From July to September 2019, elderly frail patients who were treated at the cardiovascular department of our hospital were enrolled.Basic clinical data and fall-related information of patients were collected.Patients were divided into the fall group and the non-fall group.Results on the body mass index(BMI), TUG, 4-meter maximum walking speed(4 m MWS)and Barthel index were compared between the two groups.The correlation between TUG and each indicator was examined.Multivariate Logistic regression analysis was used to analyze the correlation between the TUG and falls in elderly patients.Results:A total of 96 eligible patients were enrolled, including 35 in the fall group and 61 in the non-fall group.The average TUG time was longer in the fall group than in the non-fall group(16.45±6.44 s vs.10.17±2.91 s, t=-6.556, P<0.001). The correlation analysis results showed that the TUG was correlated with falls and 4 m MWS( r=0.582 and 0.875, both P<0.001). Multivariate Logistic regression analysis showed that the TUG( OR=1.201, 95% CI: 1.111-1.470, P=0.004)and 4 m MWS( OR=1.146, 95% CI: 1.063-1.244, P=0.015)were risk factors for falls. Conclusions:The TUG is correlated with fall risks in elderly frail patients and should be recommended as a routine test in clinical practice.

【Objective】 To evaluate the efficacy and safety of early interventions by traditional Chinese medicine oral liquid combined with plasma exchange in the treatment of pregnant women with high titer of ABO/Rh antibodies. 【Methods】 156 pregnant women with serum antibodies presenting high titer (ABO ≥512, Rh ≥ 64) in our hospital from May 2018 to April 2021 were randomly divided into traditional Chinese medicine group(group Ⅰ, n=68), traditional Chinese medicine combined with plasma exchange group(group Ⅱ, n=57) and control group (n=31). The control group were given VC, VEand oxygen uptake. Group Ⅰ were further given oral administration of traditional Chinese medicine liquid on the basis of treatment of the controls. GroupⅡwas further treated with plasma exchange on the basis of group I treatment(for 20 days every month). The biochemistry, serum antibody titer and foetus intrauterine growth were monitored. The the efficacy of treatment, as well as pregnancy and neonatal conditions in the three groups were observed. 【Results】 The decrease time of antibody titer and IgG subtype titer in groupⅠ and Ⅱ, relative to the controls, were significantly better(P<0.05). The effective rate of group Ⅰ(72.59%, 49/68) and group Ⅱ(92.98%, 53 /57) were significantly higher than the controls(18.52%, 5/27, with 4 cases excluded). No HDN occurred in group II, indicating superior treatment outcome to group I and the controls. 【Conclusion】 The oral administration of traditional Chinese medicine liquid combined with plasma exchange, with good therapeutic efficacy and maternal-fetal safety, was effective for the early interventions of ABO/Rh incompatible HDN and worthy of clinical application.
