To summarize the clinical experience of Professor LIU Shangyi in treating pruritus vulvae. It is believed that women have the physiological characteristics of liver and kidney as the root， and their pubic area is easily attacked by wind-dampness pathogenic qi， so the core mechanism of pruritus vulvae is proposed as wind-dampness accumulation and deficiency of liver and kidney. The core treatment method is to dispel wind-dampness and nourish the liver and kidneys， and modify the Danggui Decoction （当归饮子） to form a self-prescribed Yinyang Formula （阴痒方） as the basic prescription to treat pruritus vulvaen.

ObjectiveTo evaluate the clinical effectiveness and safety of Bairui Granules （百蕊颗粒） in the treatment of acute pharyngitis with wind-heat syndrome. MethodsA multicenter， double-blind， double-simulation， randomised controlled trial was conducted， in which 162 patients with acute pharyngitis and wind-heat syndrome from 7 centers were recruited， and each center was divided into trial group and control group on the ratio of 2∶1. In the trial group， 108 cases were orally administered with Bairui Granules plus Reyanning Granules （热炎宁颗粒） simulant， and in the control group， 54 cases were orally administered with Reyanning Granules plus Bairui Granules simulant for 5 days， with a follow-up visit on the 6th day. Full analysis set （FAS） analysis and per protocol set （PPS） were used for analysis， respectively. The primary efficacy index was the disappearance rate of sore throat after 5-day treatment； the secondary efficacy indexes were the disappearance rate of sore throat after 3-day treatment， as well as the visual analogue score （VAS） of sore throat before treatment， every day during the treatment， and follow-up on day 6， and the traditional Chinese medicine （TCM） syndrome score was performed before treatment and at the follow-up on day 6. The effectiveness on TCM syndrome was evaluated at the follow-up on day 6， and the changes of vital signs， blood routine， urine routine， liver functions， kidney function， the adverse events before and after the treatment were recorded， and safety analysis set （SS） was analysed. Results162 patients entered the FAS and SS analyses， and 158 cases （105 cases in the trial group and 53 cases in the control group） entered the PPS analysis. FAS analysis showed that the disappearance rate of sore throat after 5-day treatment was 80.56% （87/108） in the trial group and 64.81% （35/54） in the control group， and the difference between groups was statistically significant （χ² = 5.10， P = 0.0239）. PPS analysis showed that the disappearance rate of sore throat after 5-day treatment was 80.00% （84/105） in the trial group and 64.15% （34/53） in the control group， and the difference between groups was statistically significant （χ² =4.85， P = 0.0277）. FAS and SS analyses both showed that the difference in disappearance rate of sore throat between groups on 3-day treatment was not statistically significant （P＞0.05）. Compared with those before treatment， the VAS scores of sore throat were lower in both groups during treatment on day 2， 3， 4， 5， and follow-up on day 6 （P＜0.01）， but the difference between groups at each time point was not statistically significant （P＞0.05）. TCM syndrome scores of both groups at the follow-up were lower than that before treatment， and those of the trial group were lower than those of the control group （P＜0.01）. The cure rate and effective rate of TCM syndrome of the trial group were significantly higher than those of the control group （P＜0.01）. There was no significant difference in blood routine， urine routine， liver function， kidney function between groups before and after treatment （P＞0.05）， and no serious adverse events occured in both groups. ConclusionBairui Granules showed clinical effectiveness in the treatment of acute pharyngitis of wind-heat syndrome， and it could significantly improve the clinical symptoms， accelerate the disappearance time of sore throat with good safety.

ObjectiveTo investigate the impact of early intervention with Yishen Huazhuo prescription （YHP） on the learning and memory of accelerated aging model mice， as well as its underlying mechanism. MethodForty-eight 3-month-old male SAMP8 mice were randomly assigned into four groups， including the model group， low-dose YHP group， high-dose YHP group， and donepezil group. Additionally， 24 SAMR1 mice of the same age were divided into a control group and a YHP treatment control group， each consisting of 12 mice. The YHP groups received YHP at doses of 6.24 g·kg^-1 and 12.48 g·kg^-1， while the donepezil group was treated with donepezil at a dose of 0.65 mg·kg^-1. The model group and control groups were given physiological saline. The mice were gavaged once daily for a duration of four weeks. Spatial learning and memory abilities of mice were assessed using the Morris water maze test. Immunofluorescence staining was employed to evaluate neuronal density as well as expression levels of M1 microglial （MG） polarization marker inducible nitric oxide synthase （iNOS） and M2 MG polarization marker arginase-1 （Arg-1） in the hippocampus region. Enzyme-linked immunosorbent assay （ELISA） was used to measure serum levels of pro-inflammatory factor interleukin 1β （IL-1β） and anti-inflammatory factor transforming growth factor-β₁ （TGF-β₁）. Furthermore， Western blot analysis was conducted to determine expressions of amyloid β peptide1-42 （Aβ_1-42） along with triggering receptor expressed on myeloid cells 2 （TREM2）/nuclear factor kappa B （NF-κB） signaling pathway-related proteins TREM2， phospho （p）-NF-κB p65， and phospho-inhibitory kappa B kinase β （IKKβ） in the hippocampus. ResultCompared with the control group， the model group exhibited a significantly prolonged escape latency （P<0.01）， a significant reduction in neuron-specific nuclear protein （NeuN） expression in the hippocampus， a significant increase in iNOS expression in MG， and a significant decrease in Arg-1 expression. The serum IL-1β content was significantly increased， while the TGF-β₁ content was significantly decreased. Additionally， there was a significant decrease in TREM2 expression in the hippocampus and significant increases in p-NF-κB p65， p-IKKβ， and Aβ_1-42 expressions （P<0.05， P<0.01）. However， no significant changes were observed in escape latency， times of crossing the platform， and hippocampal NeuN expression in the YHP treatment control group. Conversely， iNOS expression in MG as well as the hippocampal p-NF-κB p65， p-IKKβ， and Aβ_1-42 expressions were significantly decreased. Furthermore， TREM2 expression was significantly increased （P<0.05， P<0.01）. In comparison to the model group， the low-dose YHP group showed a significantly shortened escape latency and an increased number of crossing the platform （P<0.05， P<0.01）. In the high-dose YHP group， the escape latency was significantly shortened （P<0.05）. In the low-dose YHP group， high-dose YHP group， the expression of NeuN in the hippocampus was significantly increased， the expression of iNOS in MG was significantly decreased， and the expression of Arg-l was significantly increased. The serum IL-1β content was significantly decreased， while the TGF-β₁ content was significantly increased. Furthermore， the expression of TREM2 in the hippocampus was significantly increased， and the expressions of p-NF-κB p65， p-IKKβ， and Aβ_1-42 were significantly decreased （P<0.01）. ConclusionEarly YHP intervention may promote the transformation of hippocampal MG from M1 to M2 by regulating the TREM2/NF-κB signaling pathway， reduce the release of neuroinflammatory factors， protect hippocampal neurons， and reduce the deposition of Aβ_1-42， and finally delay the occurrence of learning and memory decline in SAMP8 mice.

Objective To investigate the effect of iTBS stimulation on walking function in patients with stroke.Methods Fifty patients with post-stroke walking dysfunction who met the inclusion criteria were selected for 3-week rehabilitation treatment,and were randomly divided into iTBS group(n=25)and sham group(n=25).The iTBS group was treated with conventional rehabilitation therapy combined with iTBS stimulation of contral-esional cerebellum,and the sham group was treated with conventional rehabilitation therapy plus iTBS stimulation of contralesional cerebellum.Relevant indicators were analyzed before treatment and at 21 days of treatment.Lower limb motor function scores of the two groups were compared before and after treatment.Fugl-Meyer motor function lower limb activity score,Berg Balance Scale score,Brunnstrom stage(lower limb),hamstring/quadriceps(H/Q)on the affected side,Modified Barthel index(MBI),gait analysis parameters,and TMS-MEP were used to evaluate the effectiveness of cerebellar iTBS in the rehabilitation of walking dysfunction after stroke.Results After 21 days of treatment,the improvements of Brunnstrom stage,Holden grade,Berg score,FMA score,6-minute walking dis-tance,NIHSS score and MBI score in iTBS group were significantly better than those in sham group(P<0.05).Af-ter treatment,the H/Q in iTBS group was significantly higher thanbefore(P<0.05),but there was no significant difference between the two groups(P>0.05).Stride speed,stride frequency,stride width,single support phase on the affected side and GDI score in iTBS group were significantly improved compared with sham group(P<0.05),and there was no significant difference in stride length between the two groups after treatment(P>0.05).The amplitude of MEP in the affected cerebral cortex of iTBS group was lower after treatment than before(P<0.05).Conclusion Contralesional cerebellar iTBS combined with routine rehabilitation could improve lower limb walk-ing function and daily living ability of stroke patients.

Background:Combined double-balloon enteroscopy(DBE)plays an important role in the diagnosis and treatment of patients with suspected small bowel bleeding(SSBB).Aims:To investigate the performance of combined DBE in patients with SSBB and their clinical features.Methods:A total of 94 patients with SSBB underwent combined DBE from June 2018 to April 2023 at the Third People's Hospital of Bengbu and the First Affiliated Hospital of Anhui Medical University were enrolled,and the clinical features were analyzed.Results:Fifty-four SSBB patients completed the combined DBE,and the combination rate was 57.4%.Ten patients(10.6%)stopped combined DBE due to discovery of bleeding lesions.Five patients(5.3%)stopped combined DBE due to intestinal stenosis.Twenty-five patients(26.5%)stopped combined DBE due to difficulty in insertion.Combined DBE rate in SSBB patients was correlated with the combination time and the number of previous DBE for endoscopists(P<0.05),but not the gender,age,bleeding manifestations,tobacco smoking and alcohol drinking,nutritional risk,abdominal operation history,perianal lesions,autoimmune diseases,preoperative anemia,preoperative albumin level,and enteroscopy approach(P>0.05).ROC curve showed that when the cut-off value of first insertion depth was 385 cm,the sensitivity and specificity for successful combined DBE in SSBB patients were 72.2%and 77.5%,respectively,and the area under ROC curve was 0.800(95%CI:0.705-0.875,P<0.001).Conclusions:The combined DBE rate in SSBB patients is correlated with the combination time and the number of previous DBE for endoscopists.80%of the SSBB patients are expected to complete the combined DBE when the first insertion depth is greater than 385 cm.

Objective:To compare the consistency of lymphoma multigene detection panels based on next-generation sequencing (NGS) with FISH detection of B-cell lymphoma gene rearrangement.Methods:From January 2019 to May 2023, fusion genes detected by lymphoma-related 413 genes that targeted capture sequencing of 489 B-cell lymphoma tissues embedded in paraffin were collected from Henan Cancer Hospital, and the results were compared with simultaneous FISH detection of four break/fusion genes: BCL2, BCL6, MYC, and CCND1. Consistency was defined as both methods yielding positive or negative results for the same sample. The relationship between fusion mutation abundance in NGS and the positivity rate of cells in FISH was also analyzed.Results:Kappa consistency analysis revealed high consistency between NGS and FISH in detecting the four B-cell lymphoma-related gene rearrangement ( P<0.001 for all) ; however, the detection rates of positive individuals differed for the four genes. Compared with FISH, NGS demonstrated a higher detection rate for BCL2 rearrangement, a lower detection rate for BCL6 and MYC rearrangement, and a similar detection rate for CCND1 rearrangement. No correlation was found between fusion mutation abundance in NGS and the positivity rate of cells in FISH. Conclusions:NGS and FISH detection of B-cell lymphoma gene rearrangement demonstrate overall good consistency. NGS is superior to FISH in detecting BCL2 rearrangement, inferior in detecting MYC rearrangement, and comparable in detecting CCND1 rearrangement.

Head and neck squamous cell carcinoma(HNSCC)is characterized by high recurrence or distant metastases rate and the prognosis is challenging.There is mounting evidence that tumor-infiltrating B cells(TIL-Bs)have a crucial,synergistic role in tumor control.However,little is known about the role TIL-Bs play in immune microenvironment and the way TIL-Bs affect the outcome of immune checkpoint blockade.Using single-cell RNA sequencing(scRNA-seq)data from the Gene Expression Omnibus(GEO)database,the study identified distinct gene expression patterns in TIL-Bs.HNSCC samples were categorized into TIL-Bs inhibition and TIL-Bs activation groups using unsupervised clustering.This classification was further validated with TCGA HNSCC data,correlating with patient prognosis,immune cell infiltration,and response to immunotherapy.We found that the B cells activation group exhibited a better prognosis,higher immune cell infiltration,and distinct immune checkpoint levels,including elevated PD-L1.A prognostic model was also developed and validated,highlighting four genes as potential biomarkers for predicting survival outcomes in HNSCC patients.Overall,this study provides a foundational approach for B cells-based tumor classification in HNSCC,offering insights into targeted treatment and immunotherapy strategies.

Tumor is one of the major diseases that endanger people’s health. At present, the treatments used for tumor include surgery, chemotherapy, radiotherapy and so on. Nonetheless, the traditional treatments have some disadvantages, such as insufficient treatment effect, liable to cause multidrug resistance, toxicity and side effect. Further research and exploration of tumor treatment schemes are still necessary. As the energy converter of cells, mitochondria are currently considered to be one of the most important targets for the design of new drugs for tumor, cardiovascular and neurological diseases. Nano-drug delivery carriers have the characteristics of being easily modified with active targeting groups, and it can achieve accurate targeted drug delivery to cells and organelles. This paper reviews the application of mitochondrial targeted nanoparticles in tumor diagnosis and treatment from the aspects of inhibiting tumor cell proliferation, promoting tumor cell apoptosis, inhibiting tumor recurrence and metastasis, and inducing cell autophagy.

Objective:To investigate the prevalence of diabetes in the elderly aged ≥60 years in Liaoning Province from 2017 to 2019 and analyze the impact of blood glucose control on all-cause mortality and cardiovascular disease (CVD) mortality.Methods:A survey was conducted in the elderly aged ≥60 years in Liaoning from 2017 to 2019 to collect the information about the prevalence of diabetes and other chronic diseases in the diabetes patients. The mortality of the enrolled subjects was investigated in September 2023. Cox proportional hazards regression models were used to estimate the association between blood glucose control in the elderly with diabetes and the risks of all-cause mortality and CVD mortality.Results:The crude prevalence of diabetes in the elderly aged ≥60 years was 20.2% (2 014/9 958) in Liaoning from 2017 to 2019, and the standardized prevalence rate was 19.9%. The prevalence rates of hypertension, dyslipidemia, and overweight/obesity in the diabetes patients were 77.0%, 51.7%, and 67.5% respectively. The median follow-up time was 5.5 years, and the all-cause mortality and CVD mortality rates in the diabetes patients were 244.3/10 000 person-years and 142.9/10 000 person-years, respectively. The results of the Cox proportional hazards regression model analysis showed that compared with non-diabetic individuals, diabetes patients had an increased risk of all-cause mortality by 1.68 times [hazard ratio ( HR)=1.68, 95% CI: 1.44-1.94] and an increased risk of CVD mortality by 1.56 times ( HR=1.56, 95% CI: 1.29-1.89). The differences in risks of all-cause mortality and CVD mortality between the diabetes patients with normal fasting blood glucose and glycated hemoglobin levels and people without diabetes were not significant (all P>0.05). The failure to meet either the FPG or HbA1c target increased the risk of all-cause mortality (all P<0.05). For individuals who failed to meet the HbA1c target, there was an increased risk of CVD mortality (all P<0.05). Conclusions:The comorbidity rate of chronic diseases was higher in the elderly with diabetes than in the elderly without diabetes in Liaoning. Elderly diabetes patients can benefit from good blood glucose control.

Objective To evaluate the clinical and laboratory characteristics of listeriosis in patients during preg-nancy,and improve the understanding on the disease.Methods Clinical characteristics and laboratory detection re-sults of 18 pregnant women with gestational listeriosis admitted to two hospitals in Shanxi from 2012 to 2023 were analyzed retrospectively.Results Among the 18 pregnant women,1,3 and 14 cases developed listeriosis in the ear-ly,middle and late pregnancy,respectively(including 2 cases of dichorionic diamniotic twin pregnancy).The main clinical manifestations were fever(n=17,94.44％),accompanied by vaginal bleeding(n=5,27.78％),abdominal pain(n=4,22.22％),and headache(n=2,11.11％).White blood cell count,neutrophil percentage,and procal-citonin level in peripheral blood of pregnant women all increased.There were 1 spontaneous abortion during early pregnancy,3 deaths during middle pregnancy,and 10 survival during late pregnancy.All pregnant women reco-vered and were discharged from hospital.Specimens with high isolation rate of Listeria monocytogenes(LM)were uterine secretion(n=11,61.11％)and whole blood(n=10,55.55％)of pregnancy women.Among the 17 new-borns of 18 pregnant women,LM was isolated from 4(23.53％)pharyngeal tracheal secretion specimens and 3(17.65％)whole blood specimens.10 cases out of 13 revealed chorioamnionitis via pathology examination of placen-ta.Antimicrobial susceptibility testing results of 15 LM strains showed that the susceptibility rates to ampicillin,compound sulfamethoxazole,and meropenem were all 100％,and the susceptibility rates to penicillin and erythro-mycin were both 93.33％.Conclusion Listeriosis during pregnancy lacks specific clinical characteristics and is prone to be misdiagnosed.The incidence of adverse pregnancy outcomes is high.The survival rate of fetus in late pregnancy is high.Empirical anti-infection treatment during early pregnancy should cover LM infection.
