Hepatic encephalopathy is a difficult and critical disease with rapid progression and limited treatment methods in the field of liver disease， and it is urgently needed to make breakthroughs in its pathogenesis. Selection of appropriate prevention and treatment strategies is of great importance in delaying disease progression and reducing the incidence and mortality rates. This article reviews the theory of “turbid toxin pathogenesis” and related prevention and treatment strategies for hepatic encephalopathy in traditional Chinese medicine/Zhuang medicine， proposes a new theory of “turbid toxin pathogenesis”， analyzes the scientific connotations of “turbid”， “toxin”， and the theory of “turbid toxin pathogenesis”， and constructs the “four-step” prevention and treatment strategies for hepatic encephalopathy， thereby establishing the new clinical prevention and treatment regimen for hepatic encephalopathy represented by “four prescriptions and two techniques” and clarifying the effect mechanism and biological basis of core prescriptions and techniques in the prevention and treatment of hepatic encephalopathy， in order to provide a reference for the prevention and treatment of hepatic encephalopathy.

Objective: To analyze the serotypes and drug resistance of Salmonella isolated from food-borne disease surveillance samples in Longwan District, Wenzhou City, Zhejiang Province, so as to provide evidence for the prevention and treatment of Salmonella infection. Methods: Salmonella strains isolated from feces or anal swabs of patients with foodborne diarrhea in Longwan District People's Hospital from 2018 to 2024 were collected. After re-identification, slide agglutination test was used to identify serotypes. The drug susceptibility test of live Salmonella strains was performed using the broth microdilution method, and the resistance patterns were analyzed. Results: A total of 2 293 samples were collected, and 186 strains of Salmonella were isolated, with a detection rate of 8.11%. The detection rate was higher from May to October. A total of 28 Salmonella serotypes were identified, with S. typhimurium (72 isolates, 38.71%), S. enteritidis (31 isolates, 16.67%), and S. London (30 isolates, 16.13%) being dominant. Among the 121 Salmonella live strains, 20 strains were susceptible to 14 antibacterial drugs. A total of 101 strains were resistant to antibacterial drugs, and the drug resistance rate was 1.65%-67.77%, with the drug resistance rate of ampicillin being the highest, and the drug resistance rate of imipenem was the lowest. S. typhimurium had the highest resistance rate to tetracycline (78.26%). S. enteritidis had the highest resistance rate to ampicillin (100.00%). S. London had the highest resistance rate to tetracycline (66.67%). Fifty-five types of drug resistance patterns were detected, showing a number of drug resistance of 1-10, of which 76 strains were multi-drug resistant, accounting for 75.25%. The predominant multidrug resistance patterns were ampicillin/sulbactam-cefazolin-ampicillin-nalidixic acid (10.53%), tetracycline-ampicillin-nalidixic acid (9.21%), and ampicillin/sulbactam-ampicillin-nalidixic acid (7.89%). Conclusions Salmonella strains isolated from foodborne diseases in Longwan District were mainly detected in summer and autumn. S. typhimurium, S. enteritidis, and S. London were the predominant serotypes. The drug resistance of Salmonella to different antibacterial drugs was different, and the drug resistance spectrum showed diversity.

Objective:To analyze the clinical adverse events of the first carbon ion therapy system in radiotherapy for cancer patients in China.Methods:A retrospective analysis was conducted on the clinical trial monitoring data of the carbon ion therapy system obtained by the Pharmacovigilance Center of Gansu Province. A descriptive study was conducted on the demographic characteristics, radiotherapy techniques, irradiation site and dose parameters, postoperative follow-up, and adverse event information of 46 tumor patients who received carbon ion therapy and participated in the clinical trial in Wuwei Cancer Hospital, Gansu Province from November 2018 to February 2019. Frequency and percentage were used to describe and analyze the occurrence of adverse events after carbon ion therapy for cancer patients in different groups. All subjects who received radiotherapy were grouped according to the treatment dose and fractionation method.Results:The median age of the 46 patients was 47 years old, and the male to female ratio was 30∶16. There were 15, 5, 8, 9, and 9 patients with head and neck, chest, abdomen, pelvic cavity, and limb spinal tumors, respectively. The total duration of radiotherapy was 2-4 weeks for 10-16 times. There were 246 adverse events in 45 cases, with an incidence of 98%. No severe adverse events occurred. The adverse events definitely related to carbon ion devices accounted for 19.1%, and no severe adverse events related to carbon ion devices occurred. According to the evaluation criteria of common terminology criteria for adverse events (CTCAE), the main adverse events were CTCAE grade 2 and below, with only 1 (2%) head and neck tumor patient (nasopharyngeal malignant tumor) experienced CTCAE grade 3 adverse events after treatment. In addition, 43 patients developed acute adverse reactions, with an incidence of 93%, mainly involving the skin, mucosa, eyes, ears, pharynx and esophagus, upper gastrointestinal tract, lower gastrointestinal tract (including pelvic cavity), lung, genitourinary tract, heart, central nervous system and hematology (white blood cells, platelets and neutrophils), etc. Conclusion:The adverse reactions of patients treated with the first carbon ion therapy system are mainly CTCAE grade 2 and below, and the clinical adverse events are mild and controllable.

Objective To develop a reasonable plan of monitoring personal internal exposure dose. Methods This paper introduced the methods of monitoring the individual dose and direct measurement of three representative radionuclides. Results The maximum monitoring periods were determined according to the radionuclide retention characteristics and the reporting standards and requirements, which were m(1)/m(T/2) ≤ 3 and m(T/2)/m(T) ≤ 3. The lower detection limit of the instrument was derived from the monitoring periods and the annual radionuclide intake limit, which should be lower than the derived method detection limit of the corresponding radionuclide. Then the measuring duration of the instrument that meets the corresponding conditions was derived from the derived method detection limit of the instrument and the maximum monitoring period. Conclusion Our results provide a reference for the formulation of a plan of monitoring personal internal exposure dose.

Objective:To explore the effect of nursing interventions based on systematic concept in elderly patients with type 2 diabetes.Methods:From May 2018 to August 2019, 120 elderly patients with type 2 diabetes in Hangzhou Red Cross Hospital were selected by convenience sampling. The patients were randomly divided into observation group and control group with 60 cases each. Patients in each group were given nursing interventions based on systematic concept and routine nursing respectively. The anxiety, depression, benefit finding and coping modes of the two groups were compared before and after the intervention.Results:Before the intervention, there was no statistical difference between the two groups in the scores of anxiety, depression, benefit finding and behavior pattern ( P>0.05) . After intervention, the scores of anxiety and depression in the two groups decreased, and the scores in the observation group were lower than those in the control group, with statistically significant differences ( P<0.05) . After the intervention, the scores of benefit finding of the two groups increased, and that of the observation group was higher than that of the control group, and the differences were statistically significant ( P<0.05) . After intervention, the scores of confronting of the two groups increased, and that of observation group was higher than that of the control group, and the differences were statistically significant ( P<0.05) . After intervention, the scores of avoidance and resignation in the two groups decreased, and the scores in the observation group were lower than those in the control group, with statistically significant differences ( P<0.05) . Conclusions:Systematic concept nursing can reduce the anxiety and depression of elderly patients with type 2 diabetes, improve the benefit finding, increase the sense of benefit, and urge patients to adopt a positive coping style to deal with the disease.

Objective:To develop Insulin Pen Waste Needles Disposal Behavior Scale for Diabetic Patients and test its reliability and validity.Methods:Using the model of information, motivation and behavior skills as the theoretical framework, the item pool was constructed by literature review, semi-structured interview and expert consultation, and the test scale was formed after a small sample pre-survey. In July 2022, 158 and 204 diabetes patients who self-injected insulin in Endocrinology Outpatient Department of a general hospital in Shanghai were selected by the convenient sampling method. Two questionnaires were conducted to test the reliability and validity of the scale.Results:Insulin Pen Waste Needles Disposal Behavior Scale for Diabetic Patients included four dimensions, such as disposal behavior cognition, disposal behavior motivation, disposal behavior skills, and safe disposal behavior, with a total of 16 items. Four common factors were extracted from exploratory factor analysis, and the cumulative variance contribution rate was 73.80%. Content validity index was 0.98 at the average scale level, 0.88 at the level of unanimity scale, and 0.83-1.00 at the level of each item. The results of confirmatory factor analysis showed that the scale structure was stable. The Cronbach's α coefficient of the scale was 0.908, the Cronbach's α coefficient of the four factors was 0.858-0.901, the split half reliability coefficient was 0.941, and the retest reliability coefficient was 0.819.Conclusions:The scale constructed in this study has good reliability and validity, which can provide a scientific and effective assessment tool for medical staff to evaluate the disposal behavior of discarded needles used for insulin pens in diabetic patients.

Objective:To explore the clinical features and survival of newly diagnosed follicular lymphoma (FL) patients with diffuse large B-cell lymphoma (DLBCL) component.Methods:1845 newly diagnosed FL patients aged ≥ 18 years with grades 1-3a in 11 medical centers in China from 2000 to 2020 were included, and patients with DLBCL component were screened. The clinical data and survival data of the patients were retrospectively analyzed, and the prognostic factors were screened by univariate and multivariate analysis.Results:146 patients (7.9% ) with newly diagnosed FL had DLBCL component. The median age was 56 (25-83) years, 79 males (54.1% ) . The pathology of 127 patients showed the proportion of DLBCL component. Patients were divided into two groups according to whether the proportion of DLBCL component was ≥ 50% . The study found that patients with DLBCL component ≥ 50% had higher grade 3 ratio (94.3% vs 91.9% , P=0.010) , Ki-67 index ≥ 70% ratio (58.5% vs 32.9% , P=0.013) and PET-CT SUVmax ≥ 13 ratio (72.4% vs 46.3% , P=0.030) than patients with DLBCL component<50% . All patients received CHOP or CHOP like ± rituximab chemotherapy. The overall response rate (ORR) was 88.2% , and the complete response (CR) rate was 76.4% . In the groups with different proportions of DLBCL component, there was no significant difference in the remission rate after induction treatment and the incidence of disease progression within 2 years after initiation of treatment (POD24) ( P<0.05) . The overall estimated 5-year progression free survival (PFS) rate was 58.9% , and the 5-year overall survival (OS) rate was 90.4% . The 5-year OS rate of POD24 patients was lower than that of non POD24 patients (70.3% vs 98.5% , P<0.001) . Compared with non maintenance treatment of rituximab, maintenance treatment of rituximab could not benefit the 5-year PFS rate (57.7% vs 58.8% , P=0.543) , and the 5-year OS rate had a benefit trend, but the difference was not statistically significant (100% vs 87.8% , P=0.082) . Multivariate analysis showed that failure to reach CR after induction treatment was an independent risk factor for PFS ( P=0.006) , while LDH higher than normal was an independent risk factor for OS ( P=0.031) . Conclusion:FL patients with DLBCL component ≥50% have more invasive clinical and pathological features. CHOP/CHOP like ± rituximab regimen can improve the clinical efficacy of patients. Rituximab maintenance therapy can not benefit the PFS and OS of patients. Failure to reach CR after induction therapy was the independent unfavorable factor for PFS.
