This paper summarizes professor WANG Qingguo's experience in treatment of headache based on the "achieving harmony by unblocking and balancing" concept. It is considered that although the pathogenesis of headache is generally attributed to "pain arises from obstruction" and "pain arises from malnourishment"， clinical presentations often involve a complex mixture of deficiency and excess， as well as cold and heat patterns. Professor WANG proposes the diagnostic and therapeutic theory of "achieving harmony by unblocking and balancing"， advocating for equal emphasis on "freeing the flow of qi and blood" and "regulating the balance of yin and yang". He has summarized eight treatment methods for common headache patterns. For wind-cold attacking the collaterals， treatment should focus on dispersing and unblocking through modified Gegen Decoction （葛根汤）. For wind-dampness binding， it is recommended to unblock and drain， using modified Qingshang Juantong Decoction （清上蠲痛汤）. For damp-heat congestion， unblocking and clearing is the method， using modified Toufeng Shen Formula （头风神方）. For liver-gallbladder qi constraint， unblocking and soothing is the treatment principle， and modified Sanpian Decoction （散偏汤） is suggested. For insufficiency of center qi， even supplementation method is recommended， and modified Yiqi Congming Decoction （益气聪明汤） can be used. For liver yang hyperactivity， unblocking and subduing are combined， using modified Xunlong Decoction （驯龙汤）. For deficiency-cold in the liver and stomach， warming， harmonizing， unblocking， and descending are applied， using modified Wuzhuyu Decoction （吴茱萸汤）. For blood deficiency with cold congelation， unblocking and nourishing are undertaken together， using modified Danggui Sini Decoction （当归四逆汤）. The ultimate goal is to restore the dynamic balance of yin， yang， qi， and blood in the body， thereby allevia-ting pain by restoring clarity and function to the head orifices.

ObjectiveTo investigate the mechanisms by which Renshentang treats atherosclerosis （AS） in mice， focusing on the regulation of endothelial inflammatory responses mediated by transient receptor potential vanilloid subtype 1 （TRPV1）. MethodsAn AS model was established in apolipoprotein E knockout （ApoE^-/-） mice fed a high-fat diet. The mice were randomly divided into a simvastatin group （0.02 g·kg^-1·d^-1） and low-， medium-， and high-dose Renshentang groups （1.77， 3.54， 7.08 g·kg^-1·d^-1）， with 12 mice in each group. ApoE^-/- mice were fed a high-fat diet and treated simultaneously. C57BL/6J mice fed a normal diet served as the normal group （n=9）. After continuous administration for 12 weeks， mice were anesthetized and the aortas were collected. Oil Red O staining was used to observe lipid plaque formation in the aorta. Hematoxylin-eosin （HE） staining was performed to examine pathological changes in the aortic root. Immunohistochemistry was used to analyze the levels of pro-inflammatory factors tumor necrosis factor-α （TNF-α） and interleukin-1β （IL-1β）， as well as the expression of TRPV1， phosphorylated phosphoinositide 3-kinase （p-PI3K）， and phosphorylated protein kinase B （p-Akt） in the aortic root. Real-time quantitative polymerase chain reaction （Real-time PCR） was used to detect endothelial nitric oxide synthase （eNOS） mRNA expression in the aorta， and Western blot was used to detect TRPV1 protein expression. ResultsCompared with the normal group， the model group showed a significant increase in aortic plaque formation （P<0.01） and significantly elevated levels of TNF-α and IL-1β in the aortic root （P<0.01）. The expression levels of TRPV1， p-PI3K， and p-Akt were decreased （P<0.05， P<0.01）， and eNOS mRNA expression was reduced （P<0.05， P<0.01）. Compared with the model group， all Renshentang groups significantly reduced aortic plaque formation （P<0.01）， significantly decreased TNF-α and IL-1β levels （P<0.01）， and markedly increased the expression levels of TRPV1， p-PI3K， p-Akt， and eNOS mRNA （P<0.05， P<0.01）. ConclusionRenshentang may inhibit endothelial inflammation and suppress the formation of AS by increasing TRPV1 protein expression and up-regulating the PI3K/Akt/eNOS signaling pathway， which may be one of the molecular mechanisms underlying its therapeutic effect against AS.

ObjectiveMigraine is a leading neurological disorder and the fourth most common cause of years lived with disability worldwide, affecting nearly 116 million individuals. Although pharmacological treatments are available, their efficacy is often limited by side effects and variable response rates. Repetitive transcranial magnetic stimulation (rTMS) over the dorsolateral prefrontal cortex (DLPFC) offers a safe, non-invasive alternative for migraine management. However, the neurophysiological mechanisms, particularly how rTMS modulates local cortical excitability and distributed pain-related circuits, remain poorly understood. Elucidating these mechanisms is essential for optimizing treatment protocols and improving clinical outcomes. MethodsThis study employed concurrent transcranial magnetic stimulation and electroencephalography (TMS-EEG) to investigate neuroplastic and neurocircuitry mechanisms of DLPFC-rTMS in migraine. Study 1 compared 30 migraineurs and 28 healthy controls to identify abnormalities in TMS-evoked potentials (TEPs) and significant current density (SCD) within sensory-discriminative regions including the primary somatosensory cortex (S1) and posterior insula (pINS), cognitive-affective regions including the anterior insula (aINS) and midcingulate cortex (MCC), and a descending modulatory region, the periaqueductal gray (PAG). Study 2 used a single-blind, crossover, sham-controlled design in 34 healthy participants. Each participant received both active (10 Hz, 80% RMT, 1 500 pulses) and sham DLPFC-rTMS in counterbalanced order. TMS-EEG and cold pain tolerance were assessed before and after each session. ResultsIn Study 1, migraineurs showed a significantly less negative N120 amplitude compared to healthy controls (P=0.027, Cohen’s d=0.60), indicating local intracortical disinhibition. No group differences were observed for N40, P60, or P180 components. At the source level, migraineurs exhibited significantly higher SCD in the S1, pINS, aINS, and MCC (allQ<0.05), but not in the ventroposterior thalamus (vpTHAL), mediodorsal thalamus (mdTHAL), or PAG. In Study 2, active rTMS significantly reduced SCD from pre- to post-stimulation in the S1, aINS, and MCC (all Q<0.05). Sham stimulation also reduced SCD in the S1 (Q<0.05) but not in the aINS or MCC. Although no significant group-level analgesic effect was observed between active and sham conditions (P=0.107), correlation analyses revealed that greater SCD reductions in the S1 and MCC were significantly associated with higher post-rTMS pain tolerance (R=-0.487 and -0.495, both Q<0.01) and larger improvements in pain tolerance(R=-0.487 and -0.451, both Q<0.05). No such correlations were found following sham stimulation, suggesting that the behavioural relevance of neural changes is specific to active rTMS. ConclusionThis study provides novel evidence that migraineurs exhibit both local neuroplastic abnormalities (reduced N120 amplitude) and hyperactivity in key pain-processing regions (S1, pINS, aINS, MCC). A single session of DLPFC-rTMS reduced hyperactivity in the aINS, MCC, and S1. Notably, greater reductions in the S1 and MCC were associated with improved pain tolerance. These findings identify distinct cortical circuitries, particularly within the cognitive-affective pain network, that may serve as potential biomarkers for optimizing rTMS treatment in migraine and other chronic pain conditions. Future studies should validate these results in patient populations experiencing spontaneous migraine attacks and explore multi-session or accelerated rTMS protocols.

Objective To examine the changing prevalence and antimicrobial resistance profiles of Burkholderia cepacia in 52 hospitals across China from 2015 to 2021.Methods A total of 9 261 strains of B.cepacia were collected from 52 hospitals between January 1,2015 and December 31,2021.Antimicrobial susceptibility of the strains was tested using Kirby-Bauer method or automated antimicrobial susceptibility testing systems according to a unified protocol.The results were interpreted according to the breakpoints released in the Clinical & Laboratory Standards Institute(CLSI)guidelines(2023 edition).Results A total of 9 261 strains of B.cepacia were isolated from all age groups,especially elderly patients.The proportion was 11.1％(1 032 strains)in children,significantly lower than the proportion in adults.About half(46.5％,4 310/9 261)of the strains were isolated from patients at least 60 years old and 42.3％(3 919/9 261)of the strains were isolated from young adults.Most isolates(71.1％)were isolated from sputum and respiratory secretions,followed by urine(10.7％)and blood samples(8.1％).B.cepacia isolates were highly susceptible to the five antimicrobial agents recommended in the CLSI M100 document(33rd edition,2023).B.cepacia isolates showed relatively higher resistance rates to meropenem and levofloxacin.However,the resistance rates to ceftazidime,trimethoprim-sulfamethoxazole,and minocycline remained below 8.1％.The percentage of B.cepacia strains resistant to levofloxacin was the highest compared to other antibiotics in any of the three age groups(from 12.4％in the patients＜18 years old to 20.6％in the patients aged 60 years or older).Conclusions B.cepacia is one of the clinically important non-fermenting gram-negative bacteria.Accurate and timely reporting of antimicrobial susceptibility test results and ongoing antimicrobial resistance surveillance are helpful for rational prescription of antimicrobial agents and proper prevention and control of nosocomial infections.

Objective To compare five time series models and predict the monthly incidence of bacillary dysentery in Qinghai Province in 2024,and provide reference for the prevention and control.Methods The epidemic charac-teristics of bacterial dysentery in Qinghai Province from 2014 to 2023 were analyzed.R4.3.1 software was used for establishing seasonal autoregressive integrated moving average(SARIMA)model,Holt-Winters triple exponential smoothing(Holt Winters)model,exponential smoothing(ETS)model,neural network autoregression(NNAR)model,and trigonometric seasonality,Box-Cox transformation,ARMA errors,trend and seasonal components(TBATS)model.Fitting effect of the models was analyzed and accuracy was compared.Results From 2014 to 2023,a total of 5 833 cases of bacterial dysentery were reported in Qinghai Province,without deaths,male to fe-male ratio being 1.23∶1.The highest incidence was reported in 2016(15.45 per 100 000 people),and the lowest in-cidence was reported in 2023(3.68 per 100 000 people).Incidence increased from 2014 to 2016,then decreased,showing an obvious overall downward trend.Case number in＜5 years age group was the highest,accounting for 29.76％of the total cases(n=1 736).Regarding population distribution,the top three were children in childcare institutions and scattered children(35.56％),farmers(24.65％),and students(12.62％).Except the additive Holt-Winters model,the predicted trends of the other four models were consistent with actuality.The ETS model had the best fitting effect,with a relatively balanced overall performance(training set:MAE=0.13,RMSE=0.21,MAPE=19.55％;testing set:MAE=0.11,RMSE=0.16,MAPE=28.66％).It is recommended to pre-dict the incidence of bacillary dysentery in Qinghai Province based on ETS model.Conclusion From 2014 to 2023,bacterial dysentery in Qinghai Province showed a downward trend,with the peak of the epidemic from June to Au-gust.Preschool and scattered children were high-risk groups.Among the five prediction models,ETS model has the best fitting effect,and can be used to predict the incidence of bacillary dysentery.

[Purpose]To analyze the diagnostic yield of quantitative fecal immunochemical test(FIT)at different cut-offs in colorectal cancer(CRC)screening.[Methods]The sequential screening method was adapted in Jiashan CRC screening program for local residents aged 40～74 years old,which included a quantitative FIT and high-risk factor questionnaire for primary screening and subsequent colonoscopy for the diagnostic screening.Subjects who participated in quantitative FIT were included in this study between September,2021 and August,2023.The positive predictive values(PPVs)for colorectal neoplasms were calculated at the cut-offs of 100,120,140,160,180 and 200 ng/mL of FIT.The Cochran-Armitage trend test was performed to compare the trend of PPVs at different cut-offs.The effects of different starting age and FIT cut-offs on requirement of colonoscopy and advanced neoplasia detection were assessed.[Results]A total of 58 256 individuals completed the quantitative FIT,and 3 106 had fecal hemoglobin concentrations＞100 ng/mL,among whom 2 186 underwent colonoscopic examination with a compliance rate of 70.38％.The colonoscopy detected 588 cases of non-advanced adenomas and 355 cases of advanced neoplasms(AN),in-cluding 30 cases of CRC and 325 cases of advanced adenomas.Progressively increasing the cut-off showed a decrease in PPVs of non-advanced adenomas and an increase of AN.The ratio of the rate of reduced requirement of colonoscopy to the missed rate of the progressive lesions was the smallest when the screening start age was 45 years old and the positive FIT threshold was set at 100 ng/mL.[Conclusion]There were significant differences in the diagnostic yield at different cut-offs of FIT.Increasing the cut-offs of FIT will elevate PPVs for the advanced neoplasms.

[Purpose]To analyze the trends of cancer incidence and mortality from 1991 to 2020 in Jiashan County of Zhejiang Province,and to predict trends from 2021 to 2035.[Methods]Cancer cases and deaths from 1991 to 2020 in Jiashan County were collected.The crude inci-dence rate and mortality rate,age-standardized rate(ASR)were calculated.The annual percentage change(APC)and average annual percentage change(AAPC)were calculated by Joinpoint model to analyze the trend of cancer incidence and mortality.The age-period-cohort model was used to predict the trends of cancer incidence and mortality from 2021 to 2035 and the estimated annual percentage change(EAPC)was calculated.[Results]The age-standardized incidence rates by Chinese standard population(ASIRC)in Jiashan were 159.06/105,187.25/105,and 254.37/105 during 1991-2000,2001-2010,and 2011-2020,respectively.The trends in young and middle-aged women and people above 65 years old were more predominant.Lung,stomach,colorectal,liver and female breast cancers were major incident cancers for the period from 1991 to 2020.The cancer incidence showed an increasing trend from 1991 to 2020(AAPC=2.17％,P＜0.05)and is expect-ed to continue to increase over 2021 to 2035(EAPC=3.03％,P＜0.05).The age-standardized mor-tality rates by Chinese standard population(ASMRC)in Jiashan were 119.74/105,117.79/105,and 100.11/105 during 1991-2000,2001-2010,and 2011-2020,respectively.Lung,liver,stomach,colorectal,esophageal,and pancreatic cancers were leading causes of cancer deaths from 1991 to 2020.The cancer mortality showed a decreasing trend from 1991 to 2020(AAPC=-1.00％,P＜0.05)and is expected to continue to decline over 2021 to 2035(EAPC=-1.67％,P＜0.05).[Conclusion]The mortality rate from cancers has been gradually declined in Jiashan County,while the incidence rate has increased significantly and will continue to increase in the next 15 years.High incidence of lung cancer,liver cancer,gastric cancer and colorectal cancer makes it crucial to pay close attention to key groups and strengthen the control of risk factors of high inci-dence cancer.

[Purpose]To analyze the survival of lung cancer,liver cancer and stomach cancer in Jiashan County,Zhejiang Province from 2006 to 2020.[Methods]From January 1,2006 to De-cember 31,2020,new cases of lung cancer,liver cancer and stomach cancer were collected in Jiashan County,Zhejiang Province.The 5-year observed survival rate(OSR),relative survival rate(RSR)and age-standardized relative survival rate(ARSR)by sex and age were calculated from 2006-2010,2011-2015 and 2016-2020.The observed and relative survivals were calculated using the lifetime table and Ederer Ⅱ methods,respectively,and age standardized using the Inter-national Cancer Survival Standard.Joinpoint software was utilized to compute the average annual percentage change(AAPC)for analyzing trends in various survival rates from 2006 to 2020.[Re-sults]The 5-year RSR of lung cancer,liver cancer and stomach cancer increased from 8.1％,4.8％and 23.2％(2006-2010)to 36.0％,17.6％and 48.2％(2016-2020),showing an increasing trend(AAPC=14.4％,AAPC=11.4％,AAPC=6.4％,respectively,all P＜0.05).Accordingly,the 5-year RSR of three types of malignant tumors showed an increasing trend in both men and women(all P＜0.05)except liver cancer in women(P＞0.05).The 5-year RSR of three types of malignant tu-mors in the age groups of 0～64 and 65+years old showed a significant increasing trend(all P＜0.05).The increase of lung cancer and liver cancer was greater in the age group of 0～64 years old,and the increase of gastric cancer was greater in the age group of 65+years old.[Conclusion]The 5-year survival rates of the three types of malignant tumors with the highest mortality risk in Jiashan County,Zhejiang Province all increased significantly from 2006 to 2020,indicating that the pre-vention and treatment effect of malignant tumors is significant,but the survival rate of malignant tumors varied significantly among different populations,so targeted intervention should be carried out.

In the past 50 years,Jiashan County had leveraged the platform of Zhejiang University and relied on its independent cancer prevention and treatment institute to vigorously carry out co-lorectal cancer prevention and control work,which made remarkable results and becoming a na-tional model for county-level cancer prevention and control.The paper summarized the develop-ment history of Jiashan Institute of Cancer Prevention and Treatment,the process of colorectal cancer prevention and treatment,the establishment and main results of tumor registry and three-level cancer prevention system,and looked forward to the future cancer prevention and control work in Jiashan County.
