ObjectiveTo systematically assess the public health governance capacity in Zhejiang Province, to conduct an in-depth analysis of its strengths and weaknesses, so as to provide scientific basis and strategic recommendations for further enhancement. MethodsA systematic collection of policy documents, public information reports, and research literature related to public health governance capacity in Zhejiang Province from 2002 to 2023 was conducted (encompassing a total of 1 263 policy documents, 138 pieces of information reports and 631 research articles). Based on the evaluation criteria suitable for public health systems previously developed by the research team, the basic status and magnitude of change in public health governance capacity in Zhejiang Province was evaluated. Additionally, normative gap analyses were employed to identify the strengths and weaknesses. ResultsZhejiang Province ranked 4th nationwide in terms of public health governance capacity with a score of 733.4 points (1 000.0-point maximum). The province has effectively implemented the principle of health first (scoring 698.5 points in the assessment of health-first strategy implementation) and attached sufficient importance to health-related goals (scoring 658.2 points in the scientific rationality of goal setting). However, the implementation of inter-departmental coordination and incentive mechanisms only scored 178.7 points, the feasibility of management and monitoring mechanisms scored even lower at only 144.0 points, and the coverage of incentive mechanisms scored 286.0 points. ConclusionZhejiang Province has effectively implemented its health first strategy and attached great importance to health targets, but still needs to strengthen cross-departmental coordination mechanisms and health-oriented incentives.

Recently， Gastroenterological Society of Australia convened a multidisciplinary group and applied a modified Delphi process to develop the first Australian consensus statement on the application of transjugular intrahepatic portosystemic shunt （TIPS） in portal hypertension. To address the current issues of insufficient application and a lack of standardized protocols for TIPS in Australia， this consensus provides evidence-based recommendations across the key domains of preoperative preparation and assessment for TIPS， surgical standards， postoperative care and follow-up， and specific clinical indications， in order to provide standardized guidance for the comprehensive management of TIPS in liver disease patients with portal hypertension. This article gives an excerpt of the key statements in the consensus.

Objective To compare the node strength in white matter networks between depressive disorder and bipolar depression patients,analyze structural connectivity impairments across brain regions,and assess their diagnostic utility.Methods This longitudinal study initially enrolled 91 patients with a baseline diagnosis of depressive episode.All subjects underwent diffusion tensor imaging at recruitment and white matter structural weighted networks were constructed using deterministic fiber tracking.After≥9 years of naturalistic follow-up,23 patients who maintained a diagnosis of major depressive disorder(MDD group)and 18 patients who maintained a diagnosis of bipolar disorder(BD group),while 30 demographically matched healthy controls(HC group)were included for comparison.The differences in nodal connection strength within the brain white matter networks among the three groups were compared.Furthermore,the receiver operator characteristic(ROC)curve was utilized to evaluate the diagnostic value of the differential brain regions in distinguishing between MDD and BD.Results In the left anterior cingulate gyrus,the node strength was lower in the BD than in the MDD group(3.89±0.76 vs.4.74±0.60).However,the node strength in the right caudate nucleus(4.94±1.26 vs.3.46±0.99)and right globus pallidus(1.98±0.67 vs.1.25±0.29)was higher in the BD than in the MDD group(P<0.01,FWE-corrected).The combined connectivity strengths of three brain regions—the left anterior cingulate gyrus,right caudate nucleus and right globus pallidus—were used to differentiate between MDD and BD,and an ROC curve was plotted,with an area under the curve(AUC)of 0.95(95%CI:0.91～0.99;P<0.001).The sensitivity and the specificity were 0.89 and 0.87,respectively.Conclusion The differences in node strength between patient groups may serve as a potential neuroimaging biomarker.Integration of node connectivity strengths from these differential brain regions can achieve superior discrimination accuracy.

Objective To explore the objective facial appearance characteristics of patients with coronary heart disease(CHD).Methods From April 7,2019 to December 1,2022,313 patients with CHD were recruited from Dongzhimen Hospital,Beijing University of Chinese Medicine,Dongfang Hospital,Beijing University of Chinese Medicine,and the First Affiliated Hospital of Hunan University of Chinese Medicine,together with 293 healthy controls.Standardized facial images were obtained using the tongue-face diagnostic instrument.The face was divided into six regions:the forehead,left cheek,right cheek,nose,lips,and chin.Nine color parameters were extracted from each region,including red(R),green(G),blue(B),hue(H),saturation(S),value(V),lightness(L),red-green axis(a),and yellow-blue axis(b).Comparisons between groups were performed.Results Compared with the healthy group,in the forehead region,values of R,S,V,a,and b were higher in the coronary heart disease group,whereas B was lower(P<0.05);in the left cheek,nose,and chin regions,R,G,B,V,and L decreased,whereas S,a,and b increased(P<0.05);in the right cheek region,R,G,B,H,V,and L decreased,while S,a,and b increased(P<0.05);in the lips region,R,G,B,H,V,L,and a decreased,whereas S and b increased(P<0.05).Conclusion Compared with healthy individuals,patients with CHD present with a darker,more saturated facial complexion with reduced brightness,overall manifesting as"dark red complexion"and"dense but not bright color,"suggesting the pathogenesis of qi and blood circulation stagnation and internal blood stasis retention.The objective expression of facial features may have greater application value in syndrome differentiation and auxiliary diagnosis in traditional Chinese medicine.

Artificial intelligence(AI)has emerged as a cutting-edge technology leading the future and is a key engine for China's development.In the innovation and research of medical devices,AI has provided critical support in the areas of intelligent diagnostic assistance,intelligent therapeutic assis-tance,intelligent monitoring,life support,et al.Ma-chine learning-enabled device software functions(ML-DSFs)have become an essential component of many medical devices.Recently,the United States Food and Drug Administration(FDA)released a draft guidance titled"Marketing Submission Rec-ommendations for a Predetermined Change Con-trol Plan for Artificial Intelligence/Machine Learn-ing(AI/ML)-Enabled Device Software Functions(Draft)."that aimed to provide a forward-looking approach to foster the development of ML medical devices.By supporting iterative updates through modifications,this approach ensures the continu-ous safety and effectiveness of the devices.This guidance represents the latest in regulatory direc-tion and is especially beneficial for enhancing the quality and efficiency of clinical trials for AI prod-ucts.Therefore,we plan to provide a detailed intro-duction and interpretation of the guidance,with the aim of learning from international advanced regulatory concepts and experiences to promote the development of ML-DSFs with more profound international influence.

OBJECTIVE To investigate the current status of etiological submission for hospitalized patients in hospi-tals of a city before the antimicrobial treatment so as to provide basis for the etiological submission.METHODS From Jan.2022 to Dec.2022,a questionnaire survey was conducted for the status of etiological submission before antimicrobial treatment in 32 secondary and tertiary medical institutions of Huaian by Huaian Nosocomial Infection Management Quality Control Center.RESULTS The data from 28 hospitals were analyzed.Less awareness of sub-mission of healthcare workers and incomplete items for etiological test were the major influencing factors for the etiological submission.85.71％(24)of the hospitals have embedded the common names of antimicrobial drugs in-to the medical order system,and only 42.86％of the hospitals had the prompts for etiological submission in the information systems.A great deal of hospitals failed to execute the etiological submission and capture time for use of antibiotics according to national standards,only 5 hospitals met the standards for the capture[executing by scanning on personal digital assistant(PDA)].The majority of the hospitals only carried out'microbial culture and drug susceptibility testing',and there was deficiency in the test items.The diagnosis-related etiological submission rate of the tertiary hospitals was(87.49±10.77)％,higher than(64.45±30.59)％of the secondary hospitals(t=-2.250,P=0.036).The etiological submission rate before the antimicrobial treatment and the etiological submis-sion rate before the combined use of key drugs were higher in the tertiary hospitals than in the secondary hospi-tals,and there were no significant differences.CONCLUSIONS The hospitals vary in degree of execution of etiolog-ical submission before the antimicrobial treatment,and the secondary hospitals achieve lower effect on manage-ment than the tertiary hospitals.It is necessary for the medical institutions to carry out the etiological submission scientifically according to the standards so as to facilitate the reasonable use of antibiotics.

OBJECTIVE To establish the fingerprint of Pinghuo tea standard decoction and a method for determination of multi-component to clarify the transfer relationship of quantities and quality from pieces and standard decoction.METHODS Fifteen batches of Pinghuo tea standard decoction were prepared and the extract rate was determined;the fingerprint of the preparation was established by using high-performance liquid chromatography(HPLC);the similarity evaluation and the determination of common peaks were performed,and chemometric analysis was performed;the same method was used to determine the content of indicator components and the transfer rate was calculated.The chromatographic column was Venusil C18 column with mobile phase consisted of acetonitrile-0.1％ phosphoric acid solution (gradient elution);the column temperature was 30 ℃,and the detection wavelengths were 238 nm (0-37 min,85-102 min) and 330 nm (37-85 min) at a flow rate of 1.0 mL/min with an injection volume of 10 μL.RESULTS The similarity of HPLC fingerprints for 15 batches of Pinghuo tea standard decoction was not lower than 0.968.A total of 24 common peaks were calibrated and 9 peaks were recognized,which were as follows neochlorogenic acid (peak 3),chlorogenic acid (peak 6),geniposide (peak 9),glycyrrhizin (peak 10),galuteolin (peak 11),isochlorogenic acid A (peak 14),luteolin (peak 21),kaempferol (peak 23) and glycyrrhizic acid (peak 24).Cluster analysis,principal component analysis and orthogonal partial least squares discriminant analysis showed consistent results,all of which could classify the 15 batches of samples into three categories.The linear range of indicator components in 15 batches of Pinghuo tea standard decoction,such as geniposide,luteolin,isochlorogenic acid A,glycyrrhizin,and glycyrrhizic acid,were 0.020580-0.411600,0.001617-0.080850,0.006076-0.607600,0.005125-0.071740,and 0.017288-0.432200 mg/mL,respectively;RSDs of precision,repeatability,stability and recovery rate tests were all not higher than 4％ (n=6).The mass fractions ranged 3.2279-10.0022,0.2974-0.5546,3.3501-6.1596,0.7206-1.0733,2.0031-3.0301 mg/g;transfer rates from the pieces and standard decoction were 19.7628％-35.8405％,12.1233％-21.2540％,46.0972％-82.8694％,58.7088％-91.6296％,39.1143％-63.7106％.The transfer rates of the extract from 15 batches of Pinghuo tea standard decoction ranged from 61.15％-84.68％.CONCLUSIONS Established HPLC fingerprint and content determination methods in this study are simple and accurate,which can provide reference for the quantitative value transfer study,quality control,clinical application and the development of subsequent formulations of Pinghuo tea standard decoction.

OBJECTIVE To assess the safety profile of sintilimab in combination with chemotherapy for the treatment of cholangiocarcinoma.METHODS The data of patients with cholangiocarcinoma from January 1st,2021 to December 31st,2022 were collected and divided into control group(29 cases)and observation group(18 cases)based on different medication regimens.Patients in the control group were treated with Gemcitabine hydrochloride for injection+Cisplatin for injection or Oxaliplatin for injection,the observation group was treated with Sintilimab injection based on the control group.Patients in each group underwent blood routine,liver and kidney function,biochemical and other examinations before and after each treatment cycle to observe the occurrence of adverse drug reactions.The correlation of adverse drug reactions with drugs was evaluated with Naranjo's scale.RESULTS The correlation between blood toxicity and drug use was deemed"probable"in both groups;however,the observation group exhibited a significantly higher score,indicating a stronger correlation.In the control group,hepatotoxic reactions were classified as"suspicious"whereas in the observation group,they were categorized as"probable".The correlation of gastrointestinal symptoms between the two groups was considered"possible".Systemic symptoms,skin toxicity,musculoskeletal toxicity,endocrine toxicity and renal toxicity were all classified as having a"suspicious"correlation with drug use.The total incidence of blood toxicity in the observation group was significantly higher than control group(P=0.014).There was no statistically significant difference in the total incidences of hepatotoxic,gastrointestinal symptoms,systemic symptoms,skin toxicity,musculoskeletal toxicity,endocrine toxicity,renal toxicity,or the incidence of grade 3 or higher blood toxicity,hepatotoxic between the two groups(P＞0.05).For the patients experiencing adverse drug reactions,the symptoms were alleviated following drug discontinuation or symptomatic supportive treatment.No fatalities occurred during the treatment period.CONCLUSIONS Sintilimab combined with chemotherapy may significantly increase the risk of blood toxicity in patients with cholangiocarcinoma,especially thrombocytopenia,but the adverse reactions are within a controllable range,and the overall safety is good.

A bladder cancer patient underwent intravesical Bacillus Calmette-Guérin (BCG) instillation in Xiamen Branch, Zhongshan Hospital, Fudan University in April 2023. Following 8 instillations the patient presented with fever, cough and dyspnea, and was diagnosed as interstitial pneumonia (IP). Symptoms resolved after anti-tuberculosis and methylprednisolone treatment, with subsequent successful discharge. Using the keywords ′Bacillus Calmette-Guérin, ′ ′intravesical instillation, ′ ′pneumonia, ′ Wanfang Data, China National Knowledge Infrastructure(CNKI), Weipu(VIP), and PubMed databases were searched for relevant literature published between January 2014 and June 2024, and 20 cases of BCG instillation-induced pneumonia were retrieved, including 10 IP cases and 10 miliary pneumonia cases. Among 10 IP cases, 7 received corticosteroids combined with anti-tuberculosis therapy. Two cases unresponsive to combination therapy resulted in mortality, while others showed therapeutic efficacy. Miliary pneumonia demonstrated better prognosis, with 6 cases achieving complete remission through anti-tuberculosis monotherapy. The results indicate that severe BCG-related pneumonia generally necessitates combined anti-tuberculosis and corticosteroid therapy.
