Perimenopausal syndrome （MPS）， a common endocrine system disease， is one of the diseases responding specifically to traditional Chinese medicine （TCM）. The China Association of Chinese Medicine organized experts in endocrinology， gynecology， and interdisciplinary fields of both Western and Chinese medicine to discuss the advantages and challenges of diagnosing and treating MPS with Western medicine， TCM， and integrative medicine. Experts at the conference believe that MPS is initiated by estrogen decline and rooted in deficiency， with the pathogenesis being imbalance between Yin and Yang in the kidney. The hormone replacement therapy in Western medicine for menopause can rapidly alleviate related symptoms by quickly restoring the estrogen level and timely detect and delay complications of menopause， whereas such a therapy has certain risks， necessitating close monitoring of adverse reactions. Moreover， the various contraindications and precautions limit the clinical application of the hormone replacement therapy. TCM has advantages in synergistically alleviating symptoms such as hot flashes， sweating， sleep disorders， and emotional abnormalities of MPS without causing obvious adverse reactions. However， its efficacy is slower than the hormone replacement therapy， and the TCM evidence for preventing and treating complications of menopause remains unclear. Three suggestions were proposed for the future development of both Western and TCM for ameliorating MPS. First， an integrated diagnosis and treatment system for MPS with both Western and Chinese medicine should be established. Second， high-quality evidence-based interventions for MPS should be developed with TCM alone or in combination with Western medicine. Third， efforts should be made to promote the new TCM drug development and the interdisciplinary cooperation for treating MPS.

This study design of specific identification primers for the ITS2 sequence of F. ussuriensis. The reaction system and conditions were optimized, and PCR-nucleic acid test strips were constructed to realize the visual detection of F. ussuriensis Bark. Through molecular cloning and sequencing technology, we constructed a positive control for F. ussuriensis DNA and formulated quality standards. The established method was evaluated for sensitivity, specificity and reproducibility, and the authenticity of the commercially available samples was identified. Results demonstrated that based on the ITS2 sequences, F. ussuriensis and its mixed forgeries could be distinguished. The PCR products of the authentic F. ussuriensis on test strips showed two bands in the T and C lines, while the pseudo products and negative control showed only one band in the C line, which was consistent with the results of agarose gel electrophoresis. The specificity was 100%, and the sensitivity of the PCR-nucleic acid test strip was up to 0.1 ng·μL^-1, which was 10 times higher than that of the gel electrophoresis assay. 11 out of 16 commercially available samples of F. ussuriensis were qualified, and 5 were unqualified. Collectively, the PCR-nucleic acid test strip method established in this study is specific, rapid, accurate and visualized, which can provide a new technical idea for the detection of F. ussuriensis.

Objective To observe the value of diffusion kurtosis imaging(DKI)radiomics for evaluating Parkinson disease(PD).Methods Totally 76 PD patients(PD group)and 80 healthy controls(HC group)were retrospectively analyzed.The subjects were divided into training set(n=125,including 61 PD and 64 HC)and test set(n=31,including 15 PD and 16 HC)at the ratio of 8:2.ROI of bilateral substantia nigra,caudate nucleus,putamen,globus pallidus and thalamus were automatically delineated on mean kurtosis(MK)images of cerebral DKI.The mean MK values(MKmean)of the above ROIs were obtained and compared between groups.Support vector machine(SVM)model was constructed based on 50 selected optimal texture features.Receiver operating characteristic(ROC)curve was drawn,and the area under the curve(AUC)was calculated to evaluate the efficacy of SVM model for evaluating PD.Results MKmean of bilateral substantia nigra,caudate nucleus and thalamus in PD group were all significantly lower than those in HC group(all P＜0.05).No significant difference of MKmean of bilateral putamen nor globus pallidus was found between groups(all P＞0.05).The sensitivity,specificity,accuracy and AUC of SVM model for evaluating PD in training set was 86.89％,93.75％,90.40％and 0.982,respectively,which in test set was 86.67％,93.75％,90.32％and 0.958,respectively.Conclusion DKI radiomics could be used to effectively evaluate PD through description of microstructural changes of cerebral nuclei.

Objective:To explore the risk factors affecting the survival and efficacy of patients with acute myeloid leukemia with myelodysplasia-related changes(AML-MRC)transformed from myelodysplastic syndrome(MDS).Methods:The clinical data of 60 patients with AML-MRC transformed from MDS who hospitalized in The Third Affiliated Hospital of Soochow University from January 2010 to December 2021 were retrospectively analyzed.The demographic data and laboratory parameters,cytogenetic karyotypes,target genes of AML detected by next generation sequence,risk stratification,treatment regimen,therapeutic efficacy and survival outcome were documented.Rank sum test and Chi-square test or Fisher exact test were used to compare the survival and efficacy.The effects of clinical parameters,risk stratification and treatment regimens on the survival and efficacy of the AML-MRC patients were analyzed by univariate and multivariate analysis.Results:The median overall survival(OS)of the AML-MRC patients was 4.5 months,the 1-year OS rate was 28.3％,and the complete remission(CR)rate after treatment was 33.3％.The univariate analysis showed that age≥60 years,leukocytosis,severe thrombocytopenia,poor-risk group and only accepted hypomethylating agents(HMAs)or supportive therapy were the risk factors affecting OS.COX multivariate analysis showed that thrombocytopenia(HR=4.46),HMAs therapy(compared to transplantation,HR=10.47),supportive therapy(compared to transplantation,HR=25.80)and poor-risk group(compared to medium-risk group,HR=13.86)were independent hazard factors for median OS of patients with AML-MRC.The univariate analysis showed that the risk factors affecting 1-year OS in patients with AML-MRC were age ≥ 60 years,thrombocytopenia,time of transformation from MDS to AML(TTA)≥3 months,fibrinogen-albumin ratio index(FARI)≥ 0.07,CONUT score≥5,poor-risk group and supportive therapy.Binary logistic regression analysis showed that the independent risk factors for 1-year OS in AML-MRC patients were age ≥ 60 years(HR=11.23),thrombocytopenia(HR=8.71),FARI ≥ 0.07(HR=5.19)and poor-risk group(HR=14.00).The risk factors affecting CR of AML-MRC patients in univariate analysis were age ≥ 60 years,thrombocytopenia,FARI ≥ 0.1,CONUT score ≥ 5,poor-risk group and supportive therapy,while binary logistic regression analysis showed that age ≥ 60 years(HR=7.35),CONUT score ≥ 5(HR=9.60),thrombocytopenia(HR=12.05)and poor-risk group(HR=32.5)were independent risk factors affecting CR of the patients.Conclusion:The OS of AML-MRC patients is poor,old age(≥ 60 years old),supportive therapy,HMA therapy,poor-risk,thrombocytopenia,FARI ≥ 0.07 and CONUT score ≥ 5 may be associated with poor prognosis.

Objective:To analyze the clinical and genetic characteristics of a child featuring Dias-Logan syndrome.Methods:A child with speech disorders and delayed psychomotor development from childhood who was admitted to the Rehabilitation Medicine Department of Children′s Hospital Affiliated to Zhengzhou University in July 2022 was selected as the research subject. Clinical data of the child was collected. Genomic DNA was extracted from peripheral blood samples of the child and his parents. Potential variant was screened by whole exome sequencing, and candidate variant was verified by Sanger sequencing. This study was approved by the Children′s Hospital Affiliated to Zhengzhou University (Ethics No. 2023-K-011).Results:The child has presented with global developmental delay, microcephaly, special facial features and behavioral problems. Genetic testing revealed a de novo variant of the BCL11A gene, namely c. 561_567delACACGCA(p.Q187fs*7), which was classified as pathogenic (PVS1+ PS2+ PM2_Supporting). Conclusion:The heterozygous variant of BCL11A gene probably underlay the Dias-Logan syndrome in this child. Above finding has enriched the phenotypic and mutational spectrum of the BCL11A gene and provides a basis for genetic counseling and clinical decision-making.

Objective To explore the independent risk factors for central line-associated bloodstream infection(CLABSI),provide basis for developing intervention measures for infection prevention and control as well as con-ducting targeted treatment.Methods Patients who were diagnosed with CLABSI in a hospital from January 2019 to December 2023 were recruited retrospectively and defined as the infection group.According to 1:4 propensity score matching method,patients who received central venous catheter(CVC)without infection were taken as the control group.With whether CLABSI occurred as the dependent variable,the possible risk factors of the matched two groups as the independent variables,logistic regression analysis was conducted,and independent risk factors for pa-tients developing CLABSI were explored.Results A total of 42 patients in the CLABSI group and 168 patients in the non-CLABSI group were matched.Multivariate logistic regression analysis showed that high score of acute physiology and chronic health evaluation(APACHE)Ⅱ(OR=1.217,95％CI[1.094-1.357],P＜0.001),long duration of central venous catheterization(OR=1.273,95％CI[1.157-1.400],P＜0.001),and femoral venous catheterization(OR=6.846,95％CI[1.511-31.014],P=0.013)were independent risk factors for CLABSI.A total of 118 strains of pathogens were isolated from 42 CLABSI patients,with Gram-negative bacteria being the ma-jority(n=56).Conclusion High score of APACHE Ⅱ,long duration of central venous catheterization,and femo-ral venous catheterization are independent risk factors for CLABSI.The main pathogens are Gram-negative bacilli.Strict prevention and control measures for CLABSI should be implemented to reduce the risk of infection.

Hypertension and osteoporosis(OP)are common diseases in middle-aged and elderly people,and the number of patients with both diseases has gradually increased in recent years.Because the onset of the disease is hidden,it is easy to cause fractures and serious complications of heart,brain and kidney in the later stage,which not only seriously damages the quality of life of patients,but also increases the difficulty of clinical treatment.Therefore,it is particularly necessary to strengthen the research on this disease.More and more studies have found that the disorder of intestinal flora will lead to the occurrence of OP,while the intestinal flora of patients with hypertension is obviously out of balance.Therefore,this paper thinks that intestinal flora may be the key influencing factor of hypertension complicated with OP,and the imbalance of intestinal flora will lead to the imbalance of short-chain fatty acid metabolism,immune inflammatory reaction and increased sympathetic nerve activity,thus causing the imbalance of bone homeostasis and promoting the occurrence of OP.Therefore,it is suggested that regulating intestinal flora may be a new way to intervene hypertension complicated with OP.

Objective:To observe the clinical efficacy of traditional Chinese medicinal(TCM)compress combined with herbal fumigation in the treatment of acute epididymitis.Methods:This study included 74 cases of acute epididymitis treated in our hospital from December 2021 to December 2023.Using the single blind and random number methods,we divided the patients into a trial(n=37)and a control group(n=37).On the basis of routine medication with antibiotics,we treated the patients in the trial group by TCM compress combined with herbal fumigation and those in the control group by dyed pure water compress combined with herbal fumi-gation.At 3,7 and 14 days of treatment,we obtained the pain scores and maximum epididymal diameters from the patients and com-pared them between the two groups before and after treatment.Results:There were no statistically significant differences between the control and trial groups in the baseline pain scores(6.79 vs 6.85,P>0.05)and maximum epididymal diameters of the patients([1.61±0.39]vs[1.59±0.42]cm,P>0.05)or in the pain scores after3 days of treatment(4.63±0.95 vs 4.45±1.87,P>0.05).Compared with the controls,the patients of the trial group showed significantly lower pain scores(3.78±1.03 vs 1.02±0.36,P<0.05)and a higher overall effectiveness rate(75.68%vs 91.89%,P<0.05)at7 days,and markedly shorter maximum epididymal diameters at3 days([1.45±0.38]vs[1.23±0.72]cm,P<0.05)and 7 days([1.21±0.29]vs[0.98±0.15]cm,P<0.05).No statistically significant differences were observed between the control and trial groups in the pain scores(0.79±1.12 vs 0.67±0.86,P>0.05),maximum epididymal diameters([0.94±0.33]vs[0.92±0.21]cm,P>0.05)or overall effectiveness rate(91.89%vs 97.30%,P>0.05)after 14 days of treatment.Conclusion:On the basis of routine medi-cation with antibiotics,TCM compress combined with herbal fumigation can effectively relieve pain,reduce local swelling,accelerate recovery and shorten the course of treatment in patients with acute epididymitis,and is therefore worthy of clinical promotion and appli-cation.
