Ovarian cancer （OC） is a common gynecological malignant tumor in clinical practice. In the early stage，it is often asymptomatic，while in the late stage，it mainly presents with non-specific symptoms such as abdominal distension，poor appetite，and dull abdominal pain. Some patients may also have cachexia such as weight loss and anemia. Early diagnosis is difficult，and the mortality rate ranks first among gynecological malignant tumors，making OC a major challenge in clinical treatment. The classic Chinese medicine formula Guizhi Fulingwan comes from the Jingui Yaolue and has the effects of promoting blood circulation，removing blood stasis，and reducing abdominal lumps. In recent years，it has been widely used to treat OC with good results. This article summarized the clinical application of Guizhi Fulingwan in the treatment of OC from two aspects：The analysis of its basic prescriptions and clinical research. In terms of basic prescriptions，the formula has the ability to promote blood circulation，remove blood stasis，and reduce abdominal lumps. It can exert therapeutic effects considering both water and blood aspects and reduce abdominal lumps， with characteristics of simultaneous Yang warming and heat clearing and parallel supplementation and elimination. Through the methods of "circulation" and "supplementation"， it strengthens the body，dispels evil，and eliminates underlying symptoms. In clinical studies，Guizhi Fulingwan can be applied to various stages of patients with OC，which not only promotes the recovery of the body after OC surgery but also can be combined with chemotherapy and immunotherapy to synergistically treat advanced OC and enhance treatment efficacy. In addition，the formula can also alleviate various adverse reactions caused by chemotherapy，with high safety，improve patients' quality of life，prolong survival，and optimize tumor control effects. Based on the above analysis，this article elaborated on the current clinical research status of Guizhi Fulingwan combined with Western medicine in the treatment of OC and proposed suggestions and improvements to address the shortcomings in current clinical research，so as to provide reference for the clinical application of this formula in the treatment of OC and the construction of a combined traditional Chinese and Western medicine treatment model.

This study aims to establish a convenient,new and visual detection method for the field diagnosis of Pasteurella multocida(Pm).With reference to the Pm kmt1 gene conserved sequence published in GenBank,PCR amplification primers were designed,the amplified kmt1 gene was cloned into pMD19-T vector,and the recombinant plasmid standard pMD19-T-kmt 1 was estab-lished and identified by PCR and sequencing.Using pMD1 9-T-kmt 1 plasmid as template and kmt1 gene as target gene,basic primers were designed and synthesized.According to the requirements of LFD,a probe(Pm-P)was designed,and the RPA-LFD method for Pm detection was established by optimizing the reaction conditions.Specificity and sensitivity tests were carried out,and 64 clini-cal samples were tested by the method.The results showed that the established Pm RPA-LFD method could be amplified at 37 ℃ for 15 min.Escherichia coli(E.coli),Salmonella enteriditis(SE),Riemerella anatipestifer(RA),Staphylococcus,goose parvovirus(GPV),duck plague virus(DPV),Muscovy duck parvovirus(MDPV)DNA was extracted as the template,and plasmid standard pMD19-T-kmt 1 was used as the positive control.All the positive controls were negative,indicating that the method had good specificity.The plasmid standard pMD1 9-T-kmt 1 was diluted with a 10-fold ratio,and the plasmid standard with a concentration of 107-100 copies/μL was used as the template.The sensitivity was 1.50×101 copies/μ,,which was 100 times higher than that of PCR.A total of 64 clinical samples with suspected RA were subjected to testing using PCR,RPA and LAMP-LFD,with a 100％compliance rate for all three detection tests.The results show that the established RPA-LFD method has the characteristics of strong specificity,high sensitivity,fast speed and visualization,and can be applied to the field detection of Pm.

Objective To classify the foot types of young Chinese males,extract characteristic indicators of foot types,and construct a standard foot type database.Methods Foot type data from 1 483 healthy young male individuals were collected.Spectral clustering algorithm was utilized to categorize foot types,and a deep neural network(DNN)was employed for training the classification model.Layer-wise relevance propagation(LRP)and the correlation coefficient method were combined to extract foot type features,and the differences in various foot type characteristics were compared.Results Spectral clustering yielded 4 distinct foot type categories.Foot type 1 was characterized by a high-arched foot with a prominent big toe,inwardly rotated 5th toe,and a high heel with a wide foot;foot type 2 was characterized by a narrow foot with hallux valgus;foot type 3 was characterized by a low-arched foot with hallux valgus;foot type 4 was characterized by a high-arched foot with a prominent big toe.By integrating interpretable neural networks and the correlation coefficient method,nine indicators were extracted from 27 foot type indicators,including the heel to the sole length,hallux height,navicular bone height,lateral malleolus height,hallux valgus angle,5th toe angle,dorsal foot circumference,heel angle,and longitudinal arch angle.The classification model constructed with these extracted indicators achieved an overall discrimination accuracy rate of 93.67％.Conclusions Chinese young males can be classified into four typical foot types.By examining the rearfoot,midfoot,and forefoot regions,nine key foot morphology parameters,including length,height,circumference,and angle,can be extracted.These parameters provide both theoretical and empirical support for establishing normative data on foot morphology for Chinese young males and for advancing biomechanical researches on the foot and ankle.

[Purpose]To analyze the trends of cancer incidence and mortality in Changsha City from 2018 to 2022.[Methods]Based on the annual cancer registry data of Changsha City from 2018 to 2022,SAS 9.2 software was used to calculate the crude incidence/mortality rates and age-standardized incidence/mortality rates by Chinese standard population(ASIRC/ASMRC).The age-standardized rate was standardized using the population composition of China in 2000.Join-point 4.9.0.0 software was used to fit a Log-linear regression model to calculate the average annual percentage change(AAPC)and its 95％confidence interval(CI)for trend analysis.A linear regression model was applied to calculate the contribution rate of each cancer type to the trend change,with a significance level of α=0.05.[Results]From 2018 to 2022,the crude incidence rate of malig-nant tumors in Changsha City was 367.98/105(ASIRC:232.28/105),and the crude mortality rate was 192.36/105(ASMRC:106.11/105).Both incidence and mortality rates were higher in male than those in female.The incidence and mortality rates remained relatively low before age 50 but rose rapidly thereafter:the incidence peaked in the age group of 80～84 years old,while mortality peaked in the age group of 85 years old and above.The top 5 cancers by incidence were lung cancer,female breast cancer,colorectum cancer,cervical cancer,and thyroid cancer;while the top 5 cancers by mortality were lung cancer,colorectum cancer,liver cancer,female breast can-cer,and cervical cancer.The ASIRC increased significantly in the total population(AAPC=4.71％,95％CI:3.20％～6.23％),male(AAPC=2.44％,95％CI:0.35％～4.58％),and female(AAPC=7.17％,95％CI:4.00％～10.43％).The ASMRC increased significantly in the total population(AAPC=2.94％,95％CI:0.73％～5.20％)and male(AAPC=3.37％,95％CI:1.63％～5.15％),but the trend in female was not statistically significant(P＞0.05).Contribution rate analysis showed that thyroid cancer(51.25％),female breast cancer(12.18％),lymphoma(6.02％),and oral cavity and pharyngeal can-cer(5.28％)were the main cancer types contributing to the increased ASIRC;lung cancer(26.10％),colorectum cancer(14.89％),oral cavity and pharyngeal cancer(5.73％),lymphoma(5.60％),and thyroid cancer(2.08％)were the main ones contributing to the increased ASMRC;liver cancer(49.82％)and esophageal cancer(19.55％)were the main causes of decreased ASIRC,with their contribution rates to decreased ASMRC reaching 77.69％and 11.16％,respectively.[Conclusion]The disease burden of malignant tumors in Changsha City continued to increase from 2018 to 2022.It is necessary to strengthen prevention and control for cancers with a signifi-cant upward trend(such as thyroid cancer,lung cancer,and colorectum cancer)and high-risk populations(such as male and middle-aged and elderly people),while consolidating the prevention and control effects for liver cancer and esophageal cancer.

BACKGROUND: Spicy food consumption has been reported to be inversely associated with mortality from multiple diseases. However, the effect of spicy food intake on the incidence of vascular diseases in the Chinese population remains unclear. This study was conducted to explore this association. METHODS: This study was performed using the large-scale China Kadoorie Biobank (CKB) prospective cohort of 486,335 participants. The primary outcomes were vascular disease, ischemic heart disease (IHD), major coronary events (MCEs), cerebrovascular disease, stroke, and non-stroke cerebrovascular disease. A Cox proportional hazards regression model was used to assess the association between spicy food consumption and incident vascular diseases. Subgroup analysis was also performed to evaluate the heterogeneity of the association between spicy food consumption and the risk of vascular disease stratified by several basic characteristics. In addition, the joint effects of spicy food consumption and the healthy lifestyle score on the risk of vascular disease were also evaluated, and sensitivity analyses were performed to assess the reliability of the association results. RESULTS: During a median follow-up time of 12.1 years, a total of 136,125 patients with vascular disease, 46,689 patients with IHD, 10,097 patients with MCEs, 80,114 patients with cerebrovascular disease, 56,726 patients with stroke, and 40,098 patients with non-stroke cerebrovascular disease were identified. Participants who consumed spicy food 1-2 days/week (hazard ratio [HR] = 0.95, 95% confidence interval [95% CI] = [0.93, 0.97], P <0.001), 3-5 days/week (HR = 0.96, 95% CI = [0.94, 0.99], P = 0.003), and 6-7 days/week (HR = 0.97, 95% CI = [0.95, 0.99], P = 0.002) had a significantly lower risk of vascular disease than those who consumed spicy food less than once a week ( Ptrend <0.001), especially in those who were younger and living in rural areas. Notably, the disease-based subgroup analysis indicated that the inverse associations remained in IHD ( Ptrend = 0.011) and MCEs ( Ptrend = 0.002) risk. Intriguingly, there was an interaction effect between spicy food consumption and the healthy lifestyle score on the risk of IHD ( Pinteraction = 0.037). CONCLUSIONS Our findings support an inverse association between spicy food consumption and vascular disease in the Chinese population, which may provide additional dietary guidance for the prevention of vascular diseases.

Objective To explore the effect of cognitive-motor dual tasks with different cognitive loads(none,simple and difficult)on activation of prefrontal cortex and static posture control in young man.Methods From June to July,2024,27 healthy male college students were recruited in Hebei Normal University.Static postural control parameters(C90 area),lower limb electromyography data(muscle energy proportion)and pre-frontal cortex hemodynamic signals of subjects under single task without cognitive load,dual-task with simple cognitive load,and dual-task with difficult cognitive load were collected using a balanced testing and training system,a wireless surface electromyography device,and functional near-infrared spectroscopy technology.Results The C90 areas of dual-tasks with simple and difficult cognitive load were smaller than that of the single task without cognitive load(P<0.05).The proportion of β band energy in the medial and lateral gastrocnemius mus-cles in the dual-task with simple cognitive load was greater than that in the single task without cognitive load(P<0.05),while the proportion of piper band energy in the lateral gastrocnemius muscle and tibialis anterior muscle was less(P<0.05).During dual-task with difficult cognitive load,the activation levels of bilateral ventro-lateral prefrontal cortex and right dorsolateral prefrontal cortex were higher than those in the single task without cognitive load(P<0.05).Conclusion Dual tasks with appopriate cognitive loads are effective on postural stability in young man.Simple cognitive load promote posture maintenance through optimizing the neuromuscular control of the lower limb muscle groups,while difficult cognitive load through activating the right prefrontal cortex involved in working memory and executive control,involving the neurocognitive compensatory.

Objective To explore the correlation between single-leg standing posture control and ankle plantar flexor muscle stability,so as to provide a new theoretical basis for improving the ability of human posture control.Methods A total of 20 healthy male college students were randomly selected as the experimental subjects.The iBalance tester and training system was used to test the trajectory data of the center of pressure(COP)of the foot standing on one leg.The CON-TREX MJ multi-joint isokinetic test and training system was used to test the moment amplitude data during the contraction of ankle plantar flexor muscles.Univariate repeated measures variance analysis was used to analyze the standard deviation data of ankle plantar flexor moment amplitude between groups.The Pearson correlation coefficient was used to study the correlation.Results The greater the intensity of the muscle stabilization task performed by the ankle plantar flexor muscle,the greater the standard deviation of the moment amplitude.The C90 area was positively correlated with the coefficient of variation(CV)of the 10％maximum voluntary contraction(MVC)moment of ankleplantar flexor muscle(r=0.761,P＜0.05)during single-leg standing without interference.The C90 area was positively correlated with the CV(r=0.632,P＜0.05)of the 30％MVC moment of ankle plantar flexor muscle during single-leg standing.When the proprioception was interfered during single-leg standing,the C90 area was positively correlated with the CV(r=0.583,P＜0.05)of the 20％MVC moment amplitude of ankleplantar flexor muscle.Conclusions With the increasing difficulty of muscle strength stabilization performed by the ankle plantar flexor muscles,muscle stability decreases.There is a positive correlation between ankle plantar flexor strength stability and single-leg standing posture control.Compared with the case without interference,under visual and proprioceptive interference,an additional information input is reduced or disturbed,and it is more difficult to maintain body balance,and the ankle plantar flexor muscle needs a higher muscle stability in the force mode to participate in the posture control of the human body during single-leg standing.

The eIF3i gene was amplified from lamb testicular(LT)cells by PCR and cloned into pCold vector to construct the pCold-eIF3i plasmid.Plasmid PCR,double enzyme digestion and se-quencing were used to verify the results.The recombinant eIF3i protein was induced under the op-timized expression conditions.The expression and reactogenicity of the target protein were detected by SDS-PAGE and Western blot.New Zealand white rabbits were immunized with purified recom-binant eIF3i protein combined with Freund's complete and incomplete adjuvants for three times.Se-rum samples were collected after immunization.Indirect ELISA was used to detect antiserum titer,and Western blot was used to analyze antibody specificity.Indirect immunofluorescence assay(IFA)was used to detect the application effect of antibodies.The results showed that the size of LT eIF3i gene was 978 bp.The optimal expression conditions for the eIF3i recombinant protein were as follows:IPTG concentration of 0.2 mmol/L,temperature of 37 ℃,and induction time of 8 h.The recombinant eIF3i protein was expressed as an inclusion body with a size of about 36 kDa.The titer of polyclonal antibody against eIF3i protein was 1∶51 200.Western blot and IFA showed that the prepared polyclonal antibody against eIF3i protein had good reactivity and specificity.In conclusion,we successfully prepared rabbit anti-eif3i polyclonal antibody and confirmed that it could specifically recognize endogenous eIF3i protein,which laid a foundation for further study on the biological function of eIF3i protein.
