OBJECTIVE: To observe the effects of Yisui Yangxin moxibustion (moxibustion for benefiting the marrow and nourishing the heart) in sequential trial on blood pressure (BP), perimenopausal symptoms, cardiovascular function and heart rate variability (HRV) in prehypertension in perimenopausal women. METHODS: The eligible female patients of prehypertension of perimenopausal period were collected according to the inclusion criteria. Based on the requirements of open two-way qualitative response sequential trial, the sample size was not set in advance, and the matched pair design was used for random division into a moxibustion group and a health education group. The patients of the two groups were treated in pairs, and the analysis was immediately performed after the end of treatment for each pair, and the sequential trial analysis (STA) was diagrammed. The health education group provided the health education for prehypertension to the patients according to 2018 Revised Chinese Hypertension Prevention and Treatment Guidelines. In the moxibustion group, beside the health education for prehypertension, the non-suppurative moxibustion was delivered at Baihui (GV20), Guanyuan (CV4) and bilateral Neiguan (PC6) and Zusanli (ST36), once every two days, 3 treatments per week and for 4 consecutive weeks. Before treatment, in 2 and 4 weeks of treatment, as well as in 1-month follow-up after treatment, BP was measured in each group, separately. Before treatment and in 4 weeks of treatment, the observation was performed in the score of the modified Kupperman scale, and Pittsburgh sleep quality index (PSQI) score, the indexes of cardiovascular function (stroke volume [SV], cardiac output per minute [CO], stroke index [SI], cardiac index [CI], left ventricular effective pumping force [VPE], left ventricular energy efficiency [EWK], arterial compliance [AC], left ventricular ejection resistance [VER], blood viscosity (N), and microcirculation half update rate [MHR]), and heart rate variability (HRV) indexes (low frequency [LF], high frequency [HF], LF/HF, standard deviation of NN interval [SDNN], root mean square of successive differences in adjacent NN intervals [RMSSD]). RESULTS: Based on sequential test line, when the trial was performed to the 17th pair, and the test line touched the upper limit U, meaning the results of the moxibustion group was superior to the health education group, thus, the trial stopped immediately. In 2 and 4 weeks of treatment and in follow-up, the systolic blood pressure (SBP) and diastolic blood pressure (DBP) were lower when compared with those before treatment in the moxibustion group (P<0.05); SBP at each time point and DBP in 2 and 4 weeks of treatment in the moxibustion group were lower than those of the health education group (P<0.05). After treatment, the score of the modified Kupperman scale was reduced when compared with that before treatment in the moxibustion group (P<0.05). The score of the modified Kupperman scale and PSQI in the moxibustion group were lower than those of the health education group after treatment (P<0.05). After treatment, SV, CO, SI, CI and EWK were increased in comparison with the indexes before treatment in the moxibustion group (P<0.05), and VER and N were dropped (P<0.05). After treatment, SV, CO, SI, CI and EWK in the moxibustion group were higher than those of the health education group (P<0.05), and VER and N were lower (P<0.05). After treatment, in the moxibustion group, LF, HF, SDNN and RMSSD were increased in comparison with those before treatment (P<0.05), and LF/HF was declined (P<0.05). In the health education group, after treatment, LF, HF, SDNN and RMSSD decreased when compared with those before treatment (P<0.05). After treatment, LF, HF, SDNN and RMSSD in the moxibustion group were higher than those of the health education group (P<0.05), and LF/HF was lower (P<0.05). The total effective rate was 94.1% (16/17) in the moxibustion group, higher than that (41.2%, 7/17) in the health education group (P<0.05). CONCLUSION Moxibustion can reduce SBP and DBP in prehypertension of perimenopausal women, alleviate perimenopausal symptoms, improve cardiac function and adjust the overall balance of cardiac autonomic nerves.

Objective: To investigate the trends in incidence and mortality of prostate cancer in Huangpu District, Shanghai Municipality from 2002 to 2019, so as to provide insights into the prevention and treatment of prostate cancer. Methods: The incidence and mortality of prostate cancer among men in Huangpu District from 2002 to 2019 were collected from the Shanghai Cancer Registry System. The crude incidence, crude mortality, truncated age-standardized incidence (aged 35 to 64 years) and cumulative incidence (aged 0 to 74 years) of prostate cancer were calculated. The Chinese Fifth National Population Census in 2000 and the Segi's world standard population in 1960 were used to calculate Chinese-standardized rate and world-standardized rate. The trends in incidence and mortality of prostate cancer were evaluated using annual percent change (APC) and average annual percent change (AAPC). Results: A total of 2 672 cases of prostate cancer were reported in Huangpu District from 2002 to 2019, and the crude incidence was 33.35/105, the Chinese-standardized incidence was 14.93/105 and the world-standardized incidence was 12.37/105 (AAPC=7.675%, 4.886% and 4.983%, all P<0.05). The incidence of prostate cancer among males at ages of 60 to <70 years and 70 to <80 years appeared increasing trends (AAPC=4.554% and 5.045%, both P<0.05). A total of 1 214 deaths of prostate cancer were reported, and the crude mortality was 15.15/105, the Chinese-standardized mortality was 6.01/105 and the world-standardized mortality was 4.61/105 (AAPC=5.500%, 2.057% and 1.784%, all P<0.05). The mortality of prostate cancer among males at ages of 80 years and above appeared an increasing trend (AAPC=4.220%, P<0.05). Conclusions The incidence and mortality of prostate cancer appeared increasing trends in Huangpu District from 2002 to 2019, and the incidence among males at ages of 60 years and above also increased. The screening for prostate cancer among males at ages of 60 years and above should be strengthened.

Objective:The emergence of polymyxin-resistant Klebsiella pneumoniae(KPN)in clinical settings necessitates an analysis of its antibiotic resistance characteristics,epidemiological features,and risk factors for its development.This study aims to provide insights for the prevention and control of polymyxin-resistant KPN infections. Methods:Thirty clinical isolates of polymyxin-resistant KPN were collected from the Third Xiangya Hospital of Central South University.Their antibiotic resistance profiles were analyzed.The presence of carbapenemase KPC,OXA-48,VIM,IMP,and NDM was detected using colloidal gold immunochromatography.Hypervirulent KPN was initially screened using the string test.Biofilm formation capacity was assessed using crystal violet staining.Combination drug susceptibility tests(polymyxin B with meropenem,tigecycline,cefoperazone/sulbactam)were conducted using the checkerboard method.Polymyxin-related resistance genes were detected by PCR.Multi-locus sequence typing(MLST)was performed for genotyping and phylogenetic tree construction.The study also involved collecting data from carbapenem-resistant(CR)-KPN polymyxin-resistant strains(23 strains,experimental group)and CR-KPN polymyxin-sensitive strains(57 strains,control group)to analyze potential risk factors for polymyxin-resistant KPN infection through univariate analysis and multivariate Logistic regression.The induction of resistance by continuous exposure to polymyxin B and colistin E was also tested. Results:Among the 30 polymyxin-resistant KPN isolates,28 were CR-KPN,all producing KPC enzyme.Four isolates were positive in the string test.Most isolates showed strong biofilm formation capabilities.Combination therapy showed additive or synergistic effects.All isolates carried the pmrA and phoP genes,while no mcr-1 or mcr-2 genes were detected.MLST results indicated that ST11 was the predominant type.The phylogenetic tree suggested that polymyxin-resistant KPN had not caused a hospital outbreak in the institution.The use of two or more different classes of antibiotics and the use of polymyxin were identified as independent risk factors for the development of polymyxin-resistant strains.Continuous use of polymyxin induced drug resistance. Conclusion:Polymyxin-resistant KPN is resistant to nearly all commonly used antibiotics,making polymyxin-based combination therapy a viable option.No plasmid-mediated polymyxin-resistant KPN has been isolated in the hospital.Polymyxin can induce resistance in KPN,highlighting the need for rational antibiotic use in clinical settings to delay the emergence of resistance.

Actinomycosis is a rare chronic granulomatous disease characterized by granuloma formation and tissue fibrosis with sinus tracts,often misdiagnosed due to its similarity to many infectious and non-infectious diseases.This report presents a case of a 60-year-old female with more than 10 years history of rheumatoid arthritis who developed actinomycosis infection after long-term treatment with immunosuppressants and biologics,including methotrexate,leflunomide,and infliximab,leading to recurrent joint pain,poorly controlled rheumatoid arthritis activity,and persistent elevation of white blood cell counts.Abdominal CT revealed a pelvic mass and right ureteral dilation.Pathological examination of cervical tissue showed significant neutrophil infiltration and sulfur granules,indicating actinomycosis.The patient received 18 months of doxycycline treatment for the infection and continued rheumatoid arthritis therapy with leflunomide,hydroxychloroquine sulfate,and tofacitinib,resulting in improved joint symptoms and normalized white blood cell counts.After 2 years of follow-up,the patient remained stable with no recurrence.This case highlights the importance of clinicians being vigilant for infections,particularly chronic,occult infections from rare pathogens,in rheumatoid arthritis patients on potent immunosuppressants and biologics,advocating for early screening and diagnosis.

Objective To investigate the incidence and severity of symptoms in patients with gastric cancer who received chemotherapy,we constructed a symptom network to explore core symptoms and bridge symptoms.Furthermore,the study explores the association between core symptoms and Traditional Chinese Medicine(TCM)constitutions.Methods Patients with gastric cancer who received chemotherapy in the medical oncology and surgical oncology department from March to August 2023 were selected for the study using a convenience sampling method.The MD Anderson Symptom Inventory Gastrointestinal Cancer was used for evaluating gastrointestinal symptoms and their severity among patients receiving chemotherapy for gastric cancer,as well as assessing the classification of TCM constitution among patients.The symptom network model was constructed using the R programming language,and the central index was analyzed to determine the core symptoms and bridge symptoms.Binary logistic regression analysis was employed to assess the association between different physical conditions and the occurrence of core symptoms.Results A total of 346 electronic questionnaires were collected,with 340 valid ones,and the effective recovery rate was 98.3％.The 3 most prevalent and severe symptoms among the 340 patients with gastric cancer were fatigue(85.59％),lack of appetite(82.35％),and taste alteration(81.18％).The centrality index results indicated that grief exhibited the highest intensity,medium,and compactness centrality values(rs=8.23,rb=2.00,rc=0.03),making it the core symptom of this condition.Sleep disorders,lack of appetite,drowsiness,and taste alteration were identified as bridging symptoms with bridge intensities of 0.74,0.76,0.99,and 0.94 respectively.The results of Spearman correlation analysis showed that there was a positive correlation between sadness and qi-deficiency constitution,phlegm-dampness constitution(P＜0.05).The phlegm-dampness constitution was positively correlated with the taste alterations(P＜0.05).Conclusion In patients with gastric cancer,fatigue emerges as the most prominent symptom,while sadness assumes the core symptom.Additionally,sleep disorder,lack of appetite,drowsiness,and taste alteration are bridge symptoms.According to the principles of TCM constitution,qi-deficiency and phlegm-dampness are constitutions associated with a higher risk of experiencing sadness,and phlegm-dampness is a constitution associated with a higher risk of taste changes.Nurses can integrate core symptoms and TCM constitutions characteristics to optimize the strategies for symptom intervention.

Objective To evaluate the effect of the current immunization strategy for hepatitis B virus (Hepatitis B) in blocking mother-to-infant transmission in Hubei Province, and to explore the mechanism and possible influencing factors of failure of mother-to-infant blockade. Methods A multi-stage random sampling method was used to select 2 counties or districts in Hubei Province. Through maternity hospital health handbook, neonatal health record or hospital medical record system, hepatitis B virus (HBV) surface antigen (HBsAg)-positive pregnant women in 2012-2018 years were included to retrospectively investigate their delivery status and the HBV infection status of their children. Results Among the 302 newborns, 32 were positive for HBsAg, and the success rate of blockade of mother-to-infant transmission of hepatitis B was 89.45%. Further analysis showed that 68.21% (206 / 302) of newborns were delivered in township hospitals, 66.23% (200 / 302) were delivered by caesarean section and 41.72% (126 / 302) were breastfed, while 16.89% (51/302) were positive for hepatitis B virus e antigen (HBeAg), and 41.06% (124/302) were positive for anti-HBe. The vaccination rate of hepatitis B immunoglobulin (HBIG) during pregnancy was 3.31% (10/302), and the newborn HBIG vaccination rate was 94.37% (285/302). There were 84.11% (254/302) of pregnant women taking protective measures in daily life. Logistic regression analysis showed that township hospitals (OR=2.82, P<0.05), HBeAg positivity during pregnancy (OR=8.68, P<0.05), and HBIG vaccination during pregnancy (OR=12.62 , P<0.05) were risk factors for failure of mother-to-infant blockade, while anti-HBe positivity during pregnancy (OR=0.22, P<0.05), vaccination of newborns with HBIG (OR=0.20, P<0.05), and protective measures taken in daily life (OR=0.28, P<0.05) were protective factors for mother-to-infant interruption. Conclusion Deliveries in township hospitals and HBeAg-positivity during pregnancy are more likely to fail in blocking of mother-to-infant transmission of hepatitis B. HBIG vaccination during pregnancy does not reduce the risk of blockade failure. Neonatal HBIG vaccination, anti-HBe positivity during pregnancy, and protective measures in daily life can reduce the risk of blockade failure of mother-to-infant transmission of hepatitis B.

Purpose To investigate the clinicopathological characteristics and prognostic correlation of the WHO(2021)new grading system of invasive pulmonary adenocarcinoma in stageⅠ pulmonary adenocarcinoma.Methods The clinical data of 447 patients with stage Ⅰ pulmonary adenocarcinoma were collect-ed,and all cases were evaluated according to the new grading system for invasive pulmonary adenocarcinoma.The immunohis-tochemical EnVision two-step method and elastic fiber staining were used to analyze the clinicopathological features with review of the relevant literature.Results In 447 patients with stage Ⅰlung adenocarcinoma,Napsin A and TTF-1 expression were posi-tive,p40 expression was negative,and Ki-67 proliferation index was higher than 5％in 177 patients(39.6％).There were 39 cases(8.7％)of positive pleural invasion in the visceral layer revealed by elastic fiber staining.The pleural invasion in stage Ⅰpulmonary adenocarcinoma patients was significantly higher than that in grades 2 and 3,the difference was statistically significant(P＜0.05).Patients with different grades of stage Ⅰ pulmonary adenocarcinoma were associated with gender,smoking history,surgical mode,chemotherapy,targeted medication,clinical stage,pathological classification,degree of differentiation,tumor size,vascular invasion,visceral pleural invasion,spread through air space(STAS)and Ki-67 index(P＜0.05).Survival analy-sis showed that there were statistically significant differences in disease free survival(DFS)and overall survival(OS)among different grades(grade 1＞grade 2＞grade 3)(P＜0.05).Cox regression analysis showed that WHO(2021)new grading of invasive pulmonary adenocarcinoma,visceral pleural invasion and Ki-67 proliferation index were independent risk factors for prognosis of patients with stage Ⅰ pulmonary adenocarcinoma.Conclusion The WHO(2021)new grading system of invasive pulmonary adenocarcinoma has good prognostic significance for stage Ⅰ pulmonary adenocarcinoma,and appropriate intervention for high-risk patients.It can effectively assist its postoperative treatment and has application value.

Lignocellulose is the most abundant renewable organic carbon resource on earth. However, due to its complex structure, it must undergo a series of pretreatment processes before it can be efficiently utilized by microorganisms. The pretreatment process inevitably generates typical inhibitors such as furan aldehydes that seriously hinder the growth of microorganisms and the subsequent fermentation process. It is an important research field for bio-refining to recognize and clarify the furan aldehydes metabolic pathway of microorganisms and further develop microbial strains with strong tolerance and transformation ability towards these inhibitors. This article reviews the sources of furan aldehyde inhibitors, the inhibition mechanism of furan aldehydes on microorganisms, the furan aldehydes degradation pathways in microorganisms, and particularly focuses on the research progress of using biotechnological strategies to degrade furan aldehyde inhibitors. The main technical methods include traditional adaptive evolution engineering and metabolic engineering, and the emerging microbial co-cultivation systems as well as functional materials assisted microorganisms to remove furan aldehydes.
