Objective To investigate the clinical efficacy of Jia Yi Formula(composed of Trionycis Carapax,Ranunculi Ternati Radix,Pinelliae Rhizoma Praeparatum,Trichosanthis Pericarpium,Poria,Curcumae Radix,Fritillariae Thunbergii Bulbus,and Albiziae Cortex)in improving anxiety symptoms of patients with hyperthyroidism(HT).Methods A total of 84 HT patients with yin deficiency with internal heat and phlegm blended with stasis syndrome accompanied by anxiety were enrolled from the Endocrinology Outpatient and Inpatient Departments of The Affiliated Guangzhou Traditional Chinese Medicine Hospital of Guangzhou University of Chinese Medicine between February and December of 2024.Patients were randomly divided into treatment group and control group(n=42 each)using a random number table.Both groups received conventional therapy,while the control group additionally received oral methimazole,and the treatment group received Jia Yi Formula and methimazole.The treatment duration was 12 weeks for both groups.Changes in Hamilton Anxiety Scale(HAMA)scores,traditional Chinese medicine(TCM)syndrome scores,and serum thyroid hormone levels[free triiodothyronine(FT3),free thyroxine(FT4),and thyroid-stimulating hormone(TSH)]were observed.The improvement in anxiety status,TCM syndrome efficacy,and drug safety were evaluated.Results(1)In terms of TCM syndrome improvement,the total effective rate was 92.86％(39/42)in the treatment group versus 71.43％(30/42)in the control group.Intergroup comparison(by Mann-Whitney U test)showed that the TCM syndrome improvement in the treatment group was superior to the control group(P＜0.05).(2)For anxiety improvement,the total effective rate was 83.33％(38/42)in the treatment group versus 69.05％(29/42)in the control group.Intergroup comparison(by Mann-Whitney U test)showed that the anxiety improvement in the treatment group was superior to the control group(P＜0.01).(3)After treatment,both groups showed significant reductions in HAMA scores and TCM syndrome scores(P＜0.01),with greater reductions observed in the treatment group(P＜0.01).(4)Thyroid hormone levels(FT3,FT4,TSH)were significantly improved in both groups(P＜0.01),with FT3 and TSH showing greater improvement in the treatment group(P＜0.05 or P＜0.01),while FT4 improvement did not differ significantly between groups(P＞0.05).(5)The incidence of adverse reactions was 4.76％(2/42)in the treatment group and 7.14％(3/42)in the control group.Intergroup comparison(by Fisher's exact test)showed that the difference was not statistically significant(P＞0.05).Conclusion Jia Yi Formula demonstrates significant efficacy in improving anxiety,clinical symptoms,and thyroid function in HT patients with yin deficiency with internal heat and phlegm blended with stasis syndrome,showing superior benefits when used together with methimazole compared to methimazole alone.

Objective:To screen the host interaction proteins of the severe fever with thrombocytopenia syndrome virus(SFTSV)nonstructural protein(NSs)by immunoprecipitation combined with mass spectrometry analysis,to discuss the functions,subcellular localization,and biological pathways of these interaction proteins,and to provide the basis for clarifying the replication and pathogenic mechanism of SFTSV.Methods:The eukaryotic expression vectors pSFTSV-NSs-Flag(experimental group)and Flag-CMV-3(negative group)were transfected into the human embryonic kidney 293T cells,and contorl group(no treatment)was set up.The lysates of the cells in various groups were collected,and the expression and localization of SFTSV NSs in the host cells were verified by indirect immunofluorescence and Western blotting methods.The protein lysates were treated with protein A/G and immunoprecipitation was used to enrich host proteins binding to NSs.The captured interaction proteins were initially analyzed by silver staining and Coomassie brilliant blue staining to observe the differential protein bands in various groups;liquid chromatography-tandem mass spectrometry was used to obtain the information of protein sequences;the reliable proteins were retained and searched by UniProt database;Gene Ontology(GO)functional enrichment analysis,IPR,eukaryotic orthologous groups(KOGs)functional annotation,Kyoto Encyclopedia of Genes and Genomes(KEGG)signaling pathway enrichment analysis,subcellular localization,and transcription factor(TF)functional annotation were used to determine the subcellular structure,gene functions,and biological processes of the interaction proteins.Results:The immunofluorescence results showed that the SFTSV NSs expressed a single specific band at relative molecular mass 33 000 and was localized in the cytoplasm in a granular inclusion body-like manner.The silver staining and Coomassie brilliant blue staining results showed there were significant differential protein bands between experimental group and negative group.The mass spectrometry results identified 46 potential interaction proteins.The GO functional enrichment analysis,KOGs functional annotation,and KEGG signaling pathway enrichment analysis results showed that the biological pathways related to viral translation,cellular metabolism,and protein transport were enriched with a considerable number of proteins.Eight annotated proteins had intermediate filament domains.The highest percentage of subcellular localization was cytoplasmic proteins,consistent with the NSs localization site.The TF functional annotation analysis results showed one protein from the NF-Y family.Conclusion:The interaction proteins play roles in assisting the proper protein folding,participating in the cribosome translation,and forming the cytoskeleton,which may be involved in antiviral replication.These proteins can be used as candidate proteins for further study on the replication mechanism of SFTSV.

As the incidence of chronic kidney disease (CKD) increases year by year, the number of patients with CKD is increasing year by year before or during pregnancy. Pregnancy management is increasingly important for patients with kidney disease, and women with CKD face a number of challenges during pregnancy, such as the risk of kidney disease progression, fetal growth restriction, the potential teratogenicity of medications, and an increased risk of complications such as preeclampsia and preterm birth. In order to ensure a good outcome for pregnant women and the fetus, it is necessary for multidisciplinary physicians in the department of nephrology, obstetrics, reproductive health and other departments to assess the risk of pregnancy in patients with CKD in a standardized manner, adjust medication in a timely manner, and closely monitor to detect maternal and fetal complications early, stabilize the patient′s condition, and determine the safest time for pregnancy and delivery.

Objective:To evaluate the prognostic value of amplitude-integrated electroencephalogram(aEEG) on predicting long-term neurodevelopmental outcome of preterm infants.Methods:Literatures were searched in PubMed, the Cochrane library, Web of science, Wanfang database, CNKI and CBM database from inception to August, 2020.The studies which investigated the prognostic value of aEEG on neurodevelopmental outcome of preterm infants were included.Articles screening, data extraction and quality assessment were accomplished by two investigators independently, and statistical analyses were performed by Meta-disc1.4.Results:Six studies were included with 557 cases.The Meta-analysis revealed that the pooled sensitivity was 0.81 (95% CI 0.75-0.87), specificity was 0.68 (95% CI 0.63-0.73), positive likelihood ratio was 2.32(95% CI 1.52-3.52), negative likelihood ratio was 0.27(95% CI 0.19-0.37)and the area under the curve of summary receiver operating characteristic curve was 0.79(95% CI 0.75-0.82). Burst-suppression, continuous low voltage and flat trace were regard as a index of poor neurodevelopmental prognosis. Conclusion:aEEG is a valuable tool for predicting the outcome of long-term neurodevelopment in preterm infants.

Prostate cancer in patients with dwarfism is rarely reported. One case was reported in this article. The patient was admitted to the hospital due to the PSA elevation for more than 4 years. Due to the dwarf disease, the patient could not accommodate the transrectal ultrasound probe, and was highly suspected of prostate cancer.The prostate needle biopsy was not performed. Combined with the medical history, PSA level, preoperative MRI and PSMA-PET/CT examination, the patient was clinically diagnosed with localized prostate cancer, and radical surgical treatment was performed.

Stearoyl-ACP Δ⁹ desaturase (SAD) catalyzes the synthesis of monounsaturated oleic acid or palmitoleic acid in plastids. SAD is the key enzyme to control the ratio of saturated fatty acids to unsaturated fatty acids in plant cells. In order to analyze the regulation mechanism of soybean oleic acid synthesis, soybean (Glycine max) GmSAD family members were genome-wide identified, and their conserved functional domains and physicochemical properties were also analyzed by bioinformatics tools. The spatiotemporal expression profile of each member of GmSADs was detected by qRT-PCR. The expression vectors of GmSAD5 were constructed. The enzyme activity and biological function of GmSAD5 were examined by Agrobacterium-mediated transient expression in Nicotiana tabacum leaves and genetic transformation of oleic acid-deficient yeast (Saccharomyces cerevisiae) mutant BY4389. Results show that the soybean genome contains five GmSAD family members, all encoding an enzyme protein with diiron center and two conservative histidine enrichment motifs (EENRHG and DEKRHE) specific to SAD enzymes. The active enzyme protein was predicted as a homodimer. Phylogenetic analysis indicated that five GmSADs were divided into two subgroups, which were closely related to AtSSI2 and AtSAD6, respectively. The expression profiles of GmSAD members were significantly different in soybean roots, stems, leaves, flowers, and seeds at different developmental stages. Among them, GmSAD5 expressed highly in the middle and late stages of developmental seeds, which coincided with the oil accumulation period. Transient expression of GmSAD5 in tobacco leaves increased the oleic acid and total oil content in leaf tissue by 5.56% and 2.73%, respectively, while stearic acid content was reduced by 2.46%. Functional complementation assay in defective yeast strain BY4389 demonstrated that overexpression of GmSAD5 was able to restore the synthesis of monounsaturated oleic acid, resulting in high oil accumulation. Taken together, soybean GmSAD5 has strong selectivity to stearic acid substrates and can efficiently catalyze the biosynthesis of monounsaturated oleic acid. It lays the foundation for the study of soybean seed oleic acid and total oil accumulation mechanism, providing an excellent target for genetic improvement of oil quality in soybean.

OBJECTIVE:To systematically evaluate therapeutic efficacy and safety of pitavastatin comparison of atorvastatin in the treatment of primary hypedipemia in Chinese adults,and to provide evidence-based reference for clinic.METHODS:Retrieved from The Cochrane Library,PubMed,Chinese Journal Full-text Database,Wanfang database,and manually search Google Scholar,Baidu academic search engine,randomized controlled trials (RCTs) about pitavastatin (trial group) vs.atorvastatin (control group) in the treatment of primary hyperlipemia in Chinese adults were collected.After literature screening,data extraction,quality evaluation of included studies with modified Jadad scale,Meta-analysis of the levels of total cholesterol (TC),low density lipoprotein cholesterol (LDL-C),triglyceride (TG) and high-density lipoprotein cholesterol (HDL-C),response rate and the incidence of ADR was conducted by using Rev Man 5.3 statistical software.RESULTS:A total of 5 RCTs were included,involving 456 patients.Results of Meta-analysis showed that the decrease of TC level [MD=0.09,95％CI(0.01,0.16),P=0.03] in trial group was more better than control group,while the increase of HDL-C level [MD=0.08,95％ CI (0.01,0.14),P=0.03] and the decrease of the TG level [MD=-0.13,95％ CI (-0.20,-0.06),P=0.000 4] in trial group were worse than control group,with statistical significance.There was no statistical difference in the decrease of LDL-C[MD=-0.01,95％ CI (-0.13,0.10),P=0.84],response rate [OR=0.75,95％CI (0.15,3.66),P=0.72] or the incidence of ADR [OR=0.68,95 ％ CI (0.44,1.05),P=0.08] between 2 groups.CONCLUSIONS:Pitavastatin has better therapeutic efficacy in decreasing TC,but its therapeutic efficacy in decreasing LDL-C is similar to that of atorvastatin;its therapeutic efficacy in decreasing TG and increasing HDL-C is worse than that of atorvastatin.The safety of them is equivalent.

Objective To establish a suitable model for predicting the success of trial of labor after cesarean section (TOLAC) during the pregnancy at term.Methods Data for all deliveries at term with one cesarean delivery history in Shenzhen Maternity and Child healthcare hospital during 1 January 2012 to 31 December 2014 were reviewed.Variables associated with VBAC were identified and used to build a model to predict the outcome of TOLAC with multivariable logistic regression.Godness of fit and accuracy of the model were evaluated by ROC.Results A total of 531 women met inclusion criteria and underwent TOLAC.Of the women who underwent trial of labor, 448 (84.4％) had a successful VBAC, 83 failed, and 2 (0.38％) had uterine rupture.Multivariable logistic regression analysis showed that previous cesarean section (CS) time interval, neonatal birth weight (BW) and premature rupture of membranes (PROM) were independent factors affecting TOLAC outcome, and their Odds Ratios were 2.79, 1.002 and 0.244, respectively.The Logistic regression model was expressed as follows:P =1/[1 + exp (2.4 × neonatal BW + 1.03 × previous CS time interval-1.41 × PROM-10.24)].The Hosmer-lemeshow test showed that the model fitted well (x2 =123.45, P =0.996), and the prediction accuracy of the model was 86.77％.The model performed well with an AUC of 0.794 (P =0.000).Conclusions A predictive model, which contains three variables (previous CS time interval, neonatal BW and PROM), has been developed and its prediction efficiency and accuracy are satisfactory.The larger birth weight, the longer time interval from previous CS, and the absence of PROM are more likely to be failed in TOLAC.

Objective To investigate the incidence and influence factors of chronic complications of inpa-tients with type 2 diabetes mellitus(T2DM)and to provide reference for the comprehensive prevention and treat-ment. Methods A retrospective analysis was conducted to analyze the occurrence and development of chronic complications of T2DM hospitalized patients in a third-level first-class hospital of Ningxia from January to Decem-ber in 2015.Results All of the 739 T2DM patients,the total incidence of chronic complications was 74.6%.The top five chronic diseases were large vessel disease,renal disease,retinopathy,peripheral vascular disease and neuropathy. Multivariate logistic regression analysis showed that the duration of disease(OR = 1.004,95% CI:1.002~1.006)and occupation(taking workers as controls,farmers' OR =3.122,95% CI:1.420~6.861,unem-ployed persons' OR=2.771,95% CI:1.389~5.527)were the independent risk factors of chronic complications of T2DM.Conclusions The total incidence of chronic complications of T2DM is high.We should strengthen the com-prehensive intervention of controllable risk factors for reducing the incidence of complications,decreasing medical costs and enhancing overall quality of life of patients.

Enhancing soybean (Glycine max) oil production is crucial to meet the market demand of vegetable oil. Diacylglycerol acyltransferase (DGAT) catalyzes the final acylation reaction of triacylglycerol (TAG) synthesis, acting as one of the rate-limiting enzymes for oil biosynthesis in plant seeds. Here, a cDNA clone VgDGAT1A encoding the DGAT1 protein was isolated from the high oil plant Vernonia galamensis. VgDGAT1A was specifically overexpressed in soybean seeds, and several high-generation transgenic lines (T7) were obtained by continuous selection. qPCR analysis showed that VgDGAT1A was highly expressed in the mid-development stage (30-45 DAF) of the transgenic seeds. Accordingly, the DGAT enzyme activity in the transgenic seeds was increased by 7.8 folds in comparison with the wild-type controls. Seed oil and starch contents were, respectively, increased by 5.1% (Dry weight) and reduced by 2%-3% in the transgenic soybeans. Importantly, protein content was not significantly different between transgenic and control seeds. Seed weight and germination rate of the transgenic lines exhibited no negative effect. Fatty acid profiling demonstrated that antioxidant oleic acid (C18:1Δ9) content in the transgenic seed oil was elevated by 8.2% compared to the control, and correspondingly, easily-oxidized linoleic acid (C18:2Δ9,12) and linolenic acid (C18:3Δ9,12,15) were decreased by 6% and 2% respectively. Taken together, seed-specific overexpression of an exogenous VgDGAT1A gene can break the negative linkage of oil and protein contents in soybean seeds, indicating that engineering of this highly-active DGAT enzyme is an effective strategy to improve oil yield and nutritional value in oilseeds.
