RESUMEN
Objective:To predict the molecular mechanism of Biminkang Granules in the treatment of allergic rhinitis using network pharmacological methods combined with animal experiments.Methods:Active component targets and allergic rhinitis targets were screened from TCMSP, OMIM, GeneCards, TTD, DrugBank and PharmGKB databases; R language software was used to map the intersection of drug and disease targets; Cytoscape software and String platform were used to construct intersection target PPI network and conduct network topology analysis; DAVID platform was used to perform GO enrichment and KEGG pathway analysis, and perform molecular docking verification on the main active components and key targets. 32 rats were divided into a blank group of 8 and a model group of 24 using a random number table method. Model rats were induced by ovalbumin to establish an allergic rhinitis model. 24 SD rats that were successfully modeled and were randomly divided into model group, Western medicine group, and Biminkang Granules group using a random number table method, with 8 rats in each group. The Western medicine group was gavaged with 1 mg/kg of loratadine solution, the Biminkang Granules group was gavaged with 4.1 g/kg of Biminkang Granules solution, and the blank group and model group rats were gavaged with the same volume of physiological saline once a day for 2 consecutive weeks. The symptoms of rhinitis in each group of rats for 30 minutes were observed and recorded, and the pathological changes of the rat nasal mucosa were observed using HE staining. ELISA method was used to detect the levels of IL-17 and IL-6 in rat serum, and Western blot method was used to determine the expressions of TNF and STAT3 proteins in rat tissues.Results:A total of 41 target proteins of BiMinKang Dranule in the treatment of allergic rhinitis were predicted, and TNF, STAT3 and other core target proteins were obtained by PPI network topology analysis. The biological process of GO involved drug response, inflammatory response, cytokine response, etc.KEGG enrichment is involved in Th17 cell differentiation, lipid and atherosclerosis, IL-17, toll-like receptor and other pathways. Molecular docking results indicated that the main active components had good binding activity to key target proteins.Animal experiments showed that BiMinKang Dranule could improve the inflammatory symptoms of allergic rhinitis rats, down-regulate the expression of IL-17 and IL-6 in blood, and inhibit the expression of TNF and STAT3 proteins.Conclusion:Biminkang Granules can treat allergic rhinitis through multiple active components, multiple target proteins and multiple pathways, and the mechanism may be related to the regulation of Th17 cell differentiation pathway related proteins.
RESUMEN
Objective:To explore the application value of ultrasonic measurement of the pubic symphysis distance in predicting pubic symphysis diastasis(PSD) during delivery.Methods:A total of 262 pregnant women from June 2021 to July 2022 who delivered at Suzhou Wuzhong People′s Hospital and Jiangyin People′s Hospital were retrospectively analyzed. The patients were divided into PSD group of 26 cases and normal pregnant women group (control group) of 234 cases according to whether or not PSD was confirmed during postpartum follow-up. Relevant data of the two groups were collected, including the biparietal diameter and femoral length of the fetus within 7 days before delivery, the pubic symphysis distance of pregnant women when the cervix was not dilated, pubic symphysis distance when the cervix dilated to 5 cm during the first stage of delivery, and the pubic symphysis distance after delivery, the age of the pregnant woman, the gestational week, the number of pregnancies, and the birth weight of the fetus. The differences of the above relevant data between the two groups were compared.Spearman correlation analysis was used to analyze the correlation between various parameters. The occurrence of postpartum PSD, and Logistic regression was used to analyze the predictive value of various parameters on the occurrence of postpartum PSD. ROC curve was used to analyze the diagnostic efficacy of each parameters to predict PSD.Results:The fetal birth weight, number of pregnancies, pubic symphysis distance in three time points in the PSD group were significantly higher than those in the control group (all P<0.05). The age of the pregnant women was negatively correlated with the occurrence of postpartum PSD ( rs=-0.152, P=0.014). The fetal birth weight, the number of pregnancies, the pubic symphysis distance in the cervix no-dilated and the first stage of labor were positively correlated with the occurrence of postpartum PSD( rs=0.160, 0.166, 0.678, 0.581, all P<0.05). Logistic regression analysis showed that the increase of pubic symphysis distance before labor would increase the risk of postpartum PSD, and the difference was statistically significant ( OR=2 506.028, 95% CI=14.293-439 402.630, P=0.003). The increase of pubic symphysis distance at the first stage of labor increased the risk of postpartum PSD, with a statistically significant difference ( OR=10 704.027, 95% CI=33.830-3 386 803.429, P=0.002). The ROC curve analysis showed that the area under the curve of the pubic symphysis distance in the cervix no-dilated and the first stage of labor for the diagnosis of PSD were 0.896 and 0.917 respectively, the sensitivity were 0.731 and 0.885, the specificity were 0.940 and 0.829, and the corresponding critical values were 0.87 cm and 1.06 cm respectively. The area under the curve of the combination of the two parameters for the diagnosis of PSD was 0.930, the sensitivity was 0.885, and the specificity was 0.876. Conclusions:Ultrasonic measurement of pubic symphysis distance during delivery can predict the occurrence of postpartum PSD in pregnant women and can provide a basis for the occurrence and treatment of postpartum pubic symphysis separation in pregnant women.
RESUMEN
Objective:To study the role of myocardial work parameters in early identification of myocardial injury in neonatal asphyxia.Methods:From July 2020 to December 2021, neonates diagnosed with mild neonatal asphyxia admitted to the Department of Neonatology of our hospital within 24 h after birth were prospectively enrolled into the asphyxia group. Neonates without asphyxia during the same period were selected as the control group and matched with the asphyxia group for gender, gestational age and birth weight at a ratio of 1:1~1:2. The asphyxia group was subgrouped into preterm asphyxia group and term asphyxia group. All neonates received echocardiography within 24 h after birth. Multiple parameters were measured including M-mode, two-dimensional image, Doppler image, global longitudinal strain (GLS) and myocardial work parameters [global work index (GWI), global constructive work (GCW), global wasted work (GWW), global work efficiency (GWE)]. The level of serum N-terminal pro brain natriuretic peptide (NT-proBNP) was recorded in the asphyxia group. The data were compared between the asphyxia group and the control group. Correlations between myocardial work parameters and other parameters were analyzed.Results:A total of 33 cases were in the asphyxia group and 43 cases were in the control group. The preterm asphyxia group (18 cases) showed significantly lower GWI and GCW than the preterm control group (18 cases) [GWI: (702±153) mmHg vs. (879±205) mmHg, GCW: (1 016±221) mmHg vs. (1 200±271) mmHg] ( P<0.05). No differences existed in GLS, GWW and GWE. The term asphyxia group (15 cases) showed significantly lower GWW than the term control group (25 cases) [45.0 (30.0, 65.0) mmHg vs. 71.0 (35.5,85.5) mmHg] ( P<0.05). No differences existed in GLS, GWI, GCW and GWE. GWI was negatively correlated with serum NT-proBNP level ( r=-0.327, P<0.05). Conclusions:GWI and GCW may indicate myocardial injury in preterm neonates with mild asphyxia.
RESUMEN
BACKGROUND: Alzheimer's disease (AD) is a mental illness that poses a serious threat to human health worldwide. Schisandra chinensis is a natural herb that can treat the effects of AD, but its specific mechanism is still unclear. The purpose of this study was to explore the potential components and pharmacological pathways of S. chinensis in the treatment of AD. MATERIALS AND METHODS: In this study, we investigated the compound of S. chinensis and the effects of it on AD by network pharmacology. Meanwhile, the potential mechanism was proved in vitro. RESULTS: The results showed that S. chinensis contained 173 compounds. Compound-target network confirmed that (E)-9-Isopropyl-6-Methyl-5,9-Decadiene-2-One, 1-Phenyl-1,3-Butanedion, nootkatone and phenyl-2-Propanone were the main chemical constituents which highly aimed at APOE, CACNA1D, GRIN2A, and PTGS2. KEGG and GO enrichment analysis indicated that the main pathways involved neural-related signaling pathways and functions, such as nicotine addiction, GABAergic synapse, Ca2+ signaling pathway, AD, and so on. Validation experiments showed that nootkatone was able to exert anti-apoptotic effects related to Ca2+ signaling pathway by inhibiting nitric oxide production, enhancing the activity of antioxidant enzymes, upregulating the expression of anti-oxidation and anti-apoptotic proteins in vitro. CONCLUSIONS: These results illustrated that S. chinensis could regulate neuronal apoptosis through the calcium signaling pathway to exert anti-AD by integrating multi-component, multi-target and multi-pathway.

Objective:To investigate the changes of T-lymphocyte subsets, T-cell immunoglobulin and mucin domain molecule-1 (TIM-1) and TIM-3 levels, and cytokines in the peripheral blood of patients with active tuberculosis.Methods:From December 2017 to December 2018, 50 tuberculosis patients and 50 cured tuberculosis patients in Zhejiang Hospital of Integrated Chinese and Western Medicine were selected as the tuberculosis group and cured tuberculosis group, respectively. Fifty healthy individuals in the same period were selected as the control group. Flow cytometry was used to detect the T-lymphocyte subsets in the peripheral blood. The mRNA levels of TIM-1, TIM-3, interferon(IFN)-γ and interleukin(IL)-4 in peripheral blood mononuclear cells (PBMC) were detected by quantitative real-time polymerase chain reacticn (PCR). T test was used for statistical analysis. Results:The ratio of CD4 + /CD8 + T lymphocytes in the tuberculosis group (1.21±0.50) decreased significantly, comparing with those in the cured tuberculosis group (1.88±0.62) and the control group (1.92±0.82). The differences were statistically significant ( t=2.148 and 2.207, respectively, both P<0.05). The mRNA levels of TIM-1, TIM-3 and IL-4 in PBMC in the tuberculosis group were 2.16±0.37, 1.59±0.36 and 1.52±0.69, respectively, which were all higher than those in the cured tuberculosis group (1.60±1.23, 1.01±0.52 and 0.91±0.36, respectively) and the healthy control group (1.40±0.27, 0.92±0.34 and 0.79±0.42, respectively). All of these differences were statistically significant ( t=14.120, 11.440, 17.130, 12.090, 12.050 and 17.030, respectively, all P<0.05). However, the IFN-γ mRNA level (0.43±0.11) was lower than that in the cured tuberculosis group (1.74±0.72) and the control group (1.82±1.17), and the differences were both statistically significant ( t=13.880 and 11.430, respectively, both P<0.05). Conclusion:The immune dysfunction in patients with active tuberculosis may be related to the low ratio of CD4 + /CD8 + T lymphocytes, the increased expressions of TIM-1 and TIM-3, and the imbalance of helper T lymphocyte (Th)1/Th2 cytokines.
RESUMEN
Objective To compare the curative effects of multi-level puncture versus single-level puncture percutaneous vertebroplasty(PVP) for treatment of multiple-level osteoporotic vertebral body compression fractures(OVCF) in senile patients.Methods From June 2008 through November 2014,89 senile patients with fresh multiple-level OVCF underwent PVP guided by C-arm fluoroscopy in prone position.Of them,51 received PVP in which the vertebrae of multiple levels were simultaneously punctured for bone cement injection while the other 38 received PVP in which the vertebrae of multiple levels were punctured one by one for bone cement injection.The 2 groups were compatible with no significant differences in preoperative demographic data (P > 0.05).The 2 groups were compared in terms of visual analgesic scale (VAS),operation time for a single vertebra,fluoroscopy times for a single vertebra,bone cement injection amount for a single vertebra,and extraosseous cement leakage.Results PVP procedures were successful in both groups without serious complications.The VAS scores in both groups at 2 days post-operation were significantly lower than those at pre-operation(P < 0.05).The operation time and fluoroscopy times for a single vertebra in the multi-level puncture PVP group were significantly less than those in the single-level puncture PVP group (P < 0.05).There were no significant differences between the 2 groups in bone cement injection amount for a single vertebra or extraosseous cement leakage (P > 0.05).Conclusions The curative effects of multi-level puncture and single-level PVP are satisfactory for senile OVCF,but multi-level puncture PVP may lead to less operation time and less X-ray exposure.

ObjectiveTo evaluate the clinical value of prenatal ultrasonography combined with maternal serology screening for chromosomal abnormality in 15 to 20+6 gestational weeks.MethodsSix hundred and twenty-eight pregnant women (628 fetuses) in 15 to 20+6 gestational weeks were selected to undergo prenatal ultrasonography, who were in critical risk of trisomy 21 or trisomy 18 by maternal serology screening. Transabdominal ultrasonography were performed and fetal nasal bone and nuchal fold were detected. Those who had nasal bone hypoplasia, thickened nuchal fold (NF>6 mm) and other abnormal fetal soft markers underwent amniocentesis for karyotyping analysis. ResultsThere were 6 cases of nasal bone hypoplasia (0.96%, 6/628), including one case of thickened nuchal fold, two cases of echogenic bowel, two cases of choroid plexus cysts and 1 case of echogenic cardiac focus. All these 6 cases underwent amniocentesis and 2 were trisomy 21 (33.3%, 2/6). The other 4 cases had no significant chromosomal abnormality.ConclusionsPrenatal ultrasonography may improve the detection rate of chromosomal abnormality for those pregnant women who are in critical risk of chromosomal abnormality prompted by serology screening. But invasive procedures are still needed to verify the chromosomal abnormality.

RESUMEN
This study was aimed to optimize the best extraction technology of traditional Chinese medicine (TCM) Biminkang and establish the HPLC-ELSD method for determination of Astragaloside Ⅳ content. This test used heat-ing reflux which preferred ethanol as solvent extraction, extraction rate as an index to extract. By the single factor ex-periment, three factors which affect extraction rate greater were selected from the solvent concentration, extraction time, liquid ratio and extraction times. And then L9(34) orthogonal test was used to design the extraction technology of compound preparation Biminkang. HPLC-ELSD was performed on Diamonsil C18 column (250 mm í 4.6 mm, 5 μm) with H2O(A)-acetonitrile(B) (0~45 min: 22%B, 45~60 min: 22%~32%B) as mobile phase, flow rate was at 1.0 mL·min-1. The temperature of drift tube was 100℃ and the flow rate of N2 was 2.5 L·min-1. The column temperature was 30℃. The results showed that the best extraction technology of compound preparation Biminkang was liquid-solid ra-tio of 8 mL·g-1, ethanol concentration of 70%, 1.5 h for each extraction time, and extracted for three times. The re-sults showed that the presence of ethanol concentration and extraction times affected significantly. The ultimately de-termined optimal extraction conditions were as follows. The liquid-solid ratio of 8 mL/g, ethanol concentration of 70%, 1.5 h for each extraction time, and extracted for two times. The linear range of Astragaloside Ⅳ content was from 0.87 μg to 8.72 μg. And the regression equation was Y = 1.545 4X + 5.875 9, r = 0.999 7. The average re-covery rate was 95.05%. The RSD was 2.64%. It was concluded that the optimized extraction technology was stable, reasonably practicable, and suitable for industrial production.
