ObjectiveStarting from the etiology， pathogenesis， and treatment strategies of endometriosis and adenomyosis， to integrate and sort out the academic characteristics of contemporary renowned experts and schools in the field of traditional Chinese medicine gynecology. MethodsAccording to the systematic review of text and opinion （SrTO） process developed by the Joanna Briggs Institute （JBI） in Australia， this paper determined literature screening criteria by searching China National Knowledge Infrastructure （CNKI）， VIP， Wanfang， and China Biomedical Literature Database. Information was extracted after literature screening， and quality evaluation was conducted using the JBI Narrative， Text， and Opinion Systematic Review Strict Evaluation Checklist. The JBI Narrative， Opinion， Text Evaluation， and Review Tool Summary Table was used for information synthesis， and data analysis and display were conducted in the form of text and charts. ResultsThe 146 articles related to 39 renowned experts and 19 articles related to 10 schools of thought were included. Research has found that contemporary experts and schools in traditional Chinese medicine gynecology consider blood stasis as the core pathogenesis in understanding the etiology and pathogenesis of two diseases and related infertility. Their viewpoints varied from multiple aspects such as clinical symptom characteristics， meridian circulation location， pathological product evolution， disease duration， emotional psychology， lifestyle habits， preference for food and drink， innate endowment， and acquired injury. In terms of treatment， it was advocated to divide the stage， treat according to different types， adapt to the times， integrate nature and humans， and combine multiple methods to treat comprehensively when necessary. It was also recommended to skillfully use insects， make good use of classic formulas and small prescriptions， pay attention to protecting the spleen and stomach and regulating emotions， and make good use of self-formulated empirical formulas for internal or external use. Besides， individualized long-term management of patients was also advocated. ConclusionThis study applies the SrTO process to systematically summarize the academic ideas of contemporary renowned experts and schools in traditional Chinese medicine gynecology regarding the causes， mechanisms， diagnosis， and treatments of endometriosis， providing a scientific and standardized reference for future theoretical exploration.

In order to understand the prevalence and genetic variation of H9N2 subtype avian influ-enza virus in Shandong,a total 492 tracheal and lung tissue samples collected from chicken farms with respiratory symptoms in partial areas in Shandong were detected by H9 subtype AIV real-time RT-PCR,and the positive samples were inoculated with chicken embryos for two generations.Whole genome sequences of the positive strains by applying Illumina Miaseq platform,and genetic evolution and mutation at positions associating with viral pathogenicity and transmissibility were analyzed.The results showed that there were 72 samples were positive for H9 subtype AIV among the 492 samples,with a positive rate of 14.63％.Thirty-four strains of H9 subtype AIV were ob-tained from the positive samples after passing through chicken embryo,meanwhile,the 34 isolates were all H9N2 subtype AIV by whole genome sequencing analysis.By analyzing the evolutionary tree of HA and NA genes,HA and NA genes of the 34 H9N2 AIV strains belonged to Y280-like branch and F/98-like branch,respectively.Meanwhile,based on above branches,there were obvious time node subbranch,which one was"isolates before 2013",another one was"isolates after 2013".The HA cleavage sites of thirty-four H9N2 strains were all 325PSRSSR↓GLF333,which met the se-quence characteristics of the lowly pathogenic avian influenza virus,and the HA receptor binding site 226 amino acid was leucine,which had the characteristics of blinding to a-2,6 mammalian sialic acid receptors.Among the internal amino acid sites that are key to mammalian adaptation,all strains had an I368V mutation in the PB1 gene that enhanced viral transmissibility in mammals and the PB2 genes of some strains were mutated to enhance the mammalian adaptation of I292 V and A588 V.The above results illustrated that the H9N2 subtype AIV gene segments in Shandong have different degrees of recombination and gene variation,so it is necessary to strengthen the monito-ring of virus variation.

Objective:To report the clinical manifestations, structural and functional imaging features of 3 patients with progressive supranuclear palsy with predominant cerebellar ataxia (PSP-C) assisted by florzolotau ( 18F) positron emission tomography (tau PET) imaging, and conduct a literature review, aiming to provide a basis for the diagnosis and treatment of this rare type of PSP. Methods:The clinical data, brain magnetic resonance imaging, 18F-fluorodeoxyglucose PET ( 18F-FDG PET) and tau PET head imaging features of 3 patients with PSP-C who were admitted to the Department of Neurology, Peking Union Medical College Hospital from January 2019 to December 2021 were summarized, and a systematic review of related case reports or series studies from China and abroad was conducted. Results:The age of onset of the 3 patients was 55-61 years, and the disease duration was 2-5 years at the time of diagnosis. All patients had an onset of instable walking and had repeated falls, and the duration between fall and disease onset was 0.5-3.0 years, with an average of 1.5 years. At the time of diagnosis, all patients showed gait ataxia with or without limb ataxia. The results of the brain magnetic resonance imaging showed that all patients had midbrain atrophy and midbrain-to-pons ratio<0.52. The tau PET results of all patients showed significant tau protein deposition in the midbrain and mild to moderate tau protein deposition in the cerebellum, and case 2 had concomitant mild tau protein deposition in the prefrontal lobe and decreased 18F-FDG PET metabolism in this region, supporting the diagnosis of PSP. Literature review showed that 24 patients with PSP complicated with cerebellar ataxia were reported, and 23 patients provided detailed clinical data. All patients had gait ataxia on physical examination and the clinical manifestations were consistent with those of this group. Conclusions:PSP-C is characterized by early gait ataxia and falls as the core manifestations. Structural imaging shows mesencephalic atrophy, and tau PET shows mesencephalic and cerebellar uptake. In the case of atypical PSP, head magnetic resonance imaging combined with tau PET imaging is helpful to further determine the diagnosis of PSP.

Objective:To investigate the characteristics of HBV-specific T cell reactivity among pregnant, postpartum and non-pregnant women at childbearing age with chronic HBV infection.Methods:A total of 100 patients with chronic HBV infection were enrolled in this study, including 43 pregnant women (pregnant group), 26 patients giving birth within six months (postpartum group), and 31 non-pregnant patients at childbearing age (non-pregnant group). The functional HBV-specific T cells in peripheral blood were detected by ELISPOT. Clinical data as well as the results of virological and serological tests of HBV were collected for stratified analysis.Results:There was no significant difference in the number of functional HBV-specific T cells between the pregnant group and the postpartum group, but the number was significantly lesser in the pregnant group than in the non-pregnant group ( P<0.05). Furthermore, the number of functional HBV-specific T cells was significantly higher in the nucleoside analogues (NUCs)-treated pregnant women than in the NUCs-untreated pregnant women ( P<0.05). Among the patients without NUCs treatment, there were no significant differences in the numbers of hepatitis B envelope antigen/hepatitis B core antigen (HBeAg/HBcAg)-specific T cells between the pregnant group and the postpartum group, but the numbers were lower in the pregnant group than in the non-pregnant group ( P<0.05). Among the NUCs-treated patients, there was no significant difference in the number of functional HBV-specific T cells between the pregnant group and the non-pregnant group, and the numbers in the two groups were significantly higher than that in the postpartum group (both P<0.05). Additionally, receiver operating characteristic (ROC) curve indicated that the number of functional HBV-specific T cells in combination with HBV DNA load [area under the curve (AUC)=0.807] or hepatitis B surface antigen (HBsAg) levels (AUC=0.916) had a good predictive performance for hepatitis progression during pregnancy. Conclusions:Pregnancy can reduce HBV-specific T cell reactivity in women with chronic HBV infection, but NUCs treatment may improve the function of specific T cells. Routine monitoring of HBV-specific T cells during pregnancy and postpartum period can provide valuable guidance for the evaluation of immune function and treatments.

Objective To investigate the predictive value of preoperative blood inflammatory markers for the recurrence risk in patients with basal cell carcinoma(BCC).Methods A total of 225 patients with BCC were divided into the high-risk recurrence group(155 cases)and the low-risk recurrence group(70 cases).General information and preoperative hematological indicators were collected in the two groups of patients.The neutrophil-to-lymphocyte ratio(NLR),lymphocyte-to-monocyte ratio(LMR),systemic inflammation marker(SIM)and platelet-to-lymphocyte ratio(PLR)were calculated.Receiver operating characteristic(ROC)curves were used to determine the predictive value of hematological markers with statistically significant differences between the two groups for BCC recurrence and to establish optimal cutoff values.Univariate and multivariate Logistic regression analyses were conducted to identify factors influencing BCC recurrence.A multivariate Logistic regression model was established to predict the recurrence risk of BCC.Area under the curve(AUC)and the Hosmer-Lemeshow test were used to evaluate the prediction efficiency and goodness-of-fit of the model.Results ROC analysis identified that optimal cutoff values for LMR and SIM were 5.12 and 0.86,respectively.Univariate Logistic regression analysis showed that LMR,SIM,ulceration at the primary tumor site,UV exposure and tumor maximum diameter were factors influencing BCC recurrence.Multivariate Logistic regression revealed that SIM≥0.86,tumor maximum diameter≥2.0 cm and UV exposure were risk factors for BCC recurrence,while LMR≥5.12 had a protective effect.The Logistic prediction model for BCC recurrence risk was Logit(P)=-1.598-1.517×LMR+1.323×SIM+2.406×UV exposure+3.465×tumor maximum diameter,with good model fit(P=0.725)and an AUC of 0.869(95%CI:0.822-0.917)for predicting BCC recurrence risk.Conclusion Monitoring preoperative LMR and SIM levels can assist in assessing the risk of recurrence in BCC patients and provide important guidance for clinical decision-making.

OBJECTIVE To review the current research progress on pharmacoeconomics evaluation related to spinal muscular atrophy （SMA）， in order to provide valuable insights for clinical treatment， screening and medical insurance payment decision- making. METHODS A computerized search was conducted across multiple databases including PubMed， Web of Science， Embase， Scopus， Cochrane Library， EBSCOhost， CNKI， VIP， CBM and Wanfang database as well as other important health technology assessment （HTA） websites， such as National Institute for Health and Care Research，International Society of Technology Assessment in Health Care， Agency for Healthcare Research and Quality， etc. The pharmacoeconomics evaluation studies related to SMA were collected from the inception to December 31st， 2023. The literature/reports were rigorously screened based on predefined inclusion and exclusion criteria by two researchers， and the essential information from the included literature/ reports was extracted using Excel 2019. The quality of the included literature/reports was evaluated by Consolidated Health Economic Evaluation Reporting Standards 2022. RESULTS Finally， 9 articles and 15 HTA reports were included， with overall good quality of literature， but poor quality of HTA reports. There were a total of 24 studies on the pharmacoeconomics evaluation of SMA， including treatment options such as nusinersen sodium， sovaprevir， risperidone， and best supportive therapy.The review results showed that nusinersen sodium was not cost-effective in the treatment of SMA； there was no consensus on the economic viability of treatment options such as risperidone and sovaprevir； newborn/prenatal screening combined withmedication therapy was cost-effective. CONCLUSIONS newborn/prenatal screening combined with SMA medication therapy demonstrates economic advantages. It is suggested to further investigate the cost-effectiveness of new SMA drugs and SMA screening in China， taking localization parameters and medical insurance prices into account， and gradually incorporate SMA screening into the scope of neonatal genetic disease detection， in order to alleviate the financial burden of patients’ families and healthcare systems.

ObjectiveTo investigate the clinical efficacy of Gandouling tablet （GDL） on abnormal lipid metabolism in Wilson's disease （WD） and the correlation between the prediction model of hepatic steatosis and the related indexes of lipid metabolism in WD. MethodA total of 86 patients with abnormal lipid metabolism in WD were selected. The 24-hour urine copper， alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， serum triglyceride （TG）， total cholesterol （TC）， apolipoprotein B （ApoB）， low density lipoprotein cholesterol （LDL-C）， bile acid （BA）， γ-glutamyl transferase （GGT）， prediction model of hepatic steatosis ［hepatic steatosis index （HSI） and Zhejiang University index （ZJU index）］， ultrasonic attenuation coefficient imaging （ATT）， and traditional Chinese medicine （TCM） syndrome score were statistically analyzed before treatment. Pearson correlation test was used to analyze the correlation between TG， TC， LDL-C， ApoB， ALT， AST， ALT/AST， BA， GGT， TCM syndrome score， ATT， and HIS and ZJU. The patients were divided into an observation group and a control group by random number table method， with 43 cases in each group. The observation group was treated with GDL combined with sodium dimercaptopropane sulfonate （DMPS）， while the control group was only treated with DMPS as a control. After six courses of treatment， 24-hour urine copper， TC， TG， LDL-C， ApoB， HSI， ZJU， ATT， TCM syndrome score， and clinical efficiency before and after treatment were observed and compared between the two groups. The correlation between HSI and ZJU and serum TC， TG， LDL-C， ApoB， ALT， AST， ALT/AST， BA， GGT， TCM syndrome scores， and ATT was analyzed. ResultPearson correlation analysis showed that serum TC （r = 0.811）， TG （r = 0.826）， LDL-C （r = 0.802）， ApoB （r = 0.820）， ALT （r = 0.497）， ALT/AST （r = 0.826）， TCM syndrome score （r = 0.716）， and ATT （r = 0.736） were positively correlated with HSI （P<0.01）， while AST， BA， and GGT had no significant correlation with HSI. TC （r = 0.718）， TG （r = 0.765）， LDL-C （r = 0.667）， ApoB （r = 0.699）， ALT/AST （r = 0.403）， TCM syndrome score （r = 0.666）， and ATT （r = 0.684） were positively correlated with ZJU （P<0.01）. ALT， AST， BA， and GGT had no significant correlation with ZJU. The total effective rate of the observation group was 86.05 （37/43）， and that of the control group was 72.09% （31/43）. The total effective rate of the observation group was higher than that of the control group （Z = -2.301， P<0.05）. After treatment， the 24-hour urine copper of the two groups increased significantly. The levels of TC， TG， LDL-C， and ApoB were significantly decreased， and the HSI， ZJU， and ATT were significantly decreased （P<0.01）. Compared with those in the control group after treatment， the above indexes improved better in the observation group （P<0.05， P<0.01）. ConclusionGDL can effectively improve the level of copper and lipid metabolism in patients with WD， with high clinical safety and good clinical application value. The prediction model of hepatic steatosis can effectively reflect the degree of abnormal lipid metabolism in WD.

Objective:To investigate the clinicopathological features and molecular characteristics of β-catenin-deficient colorectal cancer.Methods:The clinical, pathological and molecular features of 11 colorectal cancers with β-catenin protein loss diagnosed at the 960th Hospital of People′s Liberation Army of China, from January 2012 to November 2022 were analyzed.Results:Among the 11 patients, 3 were males and 8 were females. Their age ranged from 43 to 74 years, with the median age of 59 years. Six were in the left colon and 5 were in the right colon. One of the 11 cases had lymph node metastasis, 10 cases were well and moderately differentiated adenocarcinoma, and 1 was mucinous adenocarcinoma. Eight cases were of TNM stage T4, 2 of T1 stage and 1 of Tis stage. β-catenin protein was not detected using immunohistochemistry. Sanger sequencing revealed the presence of fragment-deletion mutation in exon 3 of CTNNB1 gene, resulting in loss of β-catenin protein expression.Conclusion:β-catenin deficiency is present in a small number of colorectal cancers and may be associated with exon 3 mutations of CTNNB1 gene.

Despite decades of research,cancer continues to be a major global health concern.The human mouth appears to be a multiplicity of local environments communicating with other organs and causing diseases via microbes.Nowadays,the role of oral microbes in the development and progression of cancer has received increasing scrutiny.At the same time,bioengineering technology and nanotechnology is growing rapidly,in which the physiological activities of natural bacteria are modified to improve the therapeutic efficiency of cancers.These engineered bacteria were transformed to achieve directed genetic reprogramming,selective functional reorganization and precise control.In contrast to endotoxins produced by typical genetically modified bacteria,oral flora exhibits favorable biosafety characteristics.To outline the current cognitions upon oral microbes,engineered microbes and human cancers,related literatures were searched and reviewed based on the PubMed database.We focused on a number of oral microbes and related mechanisms associated with the tumor microenvironment,which involve in cancer occurrence and development.Whether engineering oral bacteria can be a possible application of cancer therapy is worth consideration.A deeper understanding of the relationship between engineered oral bacteria and cancer therapy may enhance our knowledge of tumor pathogenesis thus providing new insights and strategies for cancer prevention and treatment.
