ObjectiveTo analyze the adverse reactions associated with the clinical use of Banxia （Rhizoma Pinelliae）- Wutou （Aconitum） in the same formula， with the aim of providing a reference for the safety of their clinical application. MethodsLiterature on the clinical application of antagonistic herbs "Banxia-Wutou" used in the same formula， published from January 1st， 2014， to June 30th， 2023， was retrieved from databases including CNKI， VIP， Wanfang， SinoMed， PubMed， Cochrane Library， and Embase. A database was established， and information related to adverse reactions was extracted， including descriptions， classifications， specific manifestations， management and outcomes， patients' primary diseases （western medicine diseases and traditional Chinese medicine diagnoses and syndromes）， and medication information （dosage， ratio， administration routes， and dosage forms）. ResultsA total of 79 researches simultaneously used antagonistic herbs Banxia-Wutou in the same formula and reported associated advers reactions. Gastrointestinal adverse reactions were the most common， with 8 studies reporting management of adverse reactions and 3 studies reporting improvement with no intervention. Among the 11 researches， the adverse reaction relieved to extant， while other 69 researches didn't report the managment of adverse reaction and its prognosis. For the primary disease in western medicine system， chronic bronchitis and chronic obstructive pulmonary disease （COPD） were most common， while gastric pain was the most common symptom in traditional Chinese medicine with spleen and kidney deficiency and spleen stomach cold deficiency being the most frequent syndromes. The most common Banxia dosage was 10 g， while for the Wutou， Fuzi （Radix Aconiti Lateralis Praeparata） was predominant with the highest dose at 15 g. The most frequent herbal combination was Banxia-fuzi， with a 1∶1 ratio. The main administration route was oral， and the primary dosage form was decoction. ConclusionGastrointestinal adverse reactions are the most common in the clinical use of Banxia-Wutou antagonistic herb combinations. Research on the safety of "Banxia-Wutou" combinations should focus on respiratory system diseases and spleen-stomach related conditions.

ObjectiveTo observe the effects of Sargassum and Glycyrrhizae Radix et Rhizoma incompatible pair with the Haizao Yuhutang （HYT） on oxidative stress in the liver of goiter rats under the condition of 2 times the dose limit of the Pharmacopoeia of the People's Republic of China 2020. MethodA total of 128 male Wistar rats were randomly divided into a blank group， a model group， a euthyrox group （20 μg·kg^-1）， a HYT group （12.06 g·kg^-1）， a HYT without Sargassum （HYT-H） group （9.90 g·kg^-1）， a HYT without Glycyrrhizae Radix et Rhizoma （HYT-G） group （10.26 g·kg^-1）， a HYT without Sargassum and Glycyrrhizae Radix et Rhizoma （HYT-HG） group （8.10 g·kg^-1）， and a Sargassum and Glycyrrhizae Radix et Rhizoma （HG） group （3.96 g·kg^-1）. The blank group was given deionized water by gavage， and the others were given propylthiouracil （PTU） to replicate the goiter pathological model. Euthyrox was taken as a positive control drug， and the rest of the Chinese medicine groups were given the corresponding decoction by gavage， the material was collected 12 hours after the last dose. The serum levels of aspartate aminotransferase （AST）， alanine aminotransferase （ALT）， alkaline phosphatase （ALP）， and the contents of superoxide dismutase （SOD）， glutathione peroxidase （GSH-Px）， malondialdehyde （MDA）， reactive oxygen species （ROS） in liver tissue were detected in each group. The pathological changes in the liver were observed via hematoxylin-eosin （HE） staining. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was utilized to detect the mRNA expressions of Kelch-like Ech-associated protein 1 （Keap1）， nuclear factor E₂-related factor 2 （Nrf2）， heme oxygenase-1 （HO-1）， p53 and Caspase-3 in liver tissues. Western blot was adopted to detect the protein expressions of Nrf2 and HO-1 in liver tissues in oxidative stress-related signaling pathways. ResultCompared with control group， the model group showed significantly increased serum ALT level and contents of MDA and ROS in liver tissues （P<0.05， P<0.01）， significantly reduced activities of SOD and GSH-Px in the liver （P<0.01）， significantly increased mRNA expression of Keap1 （P<0.01）， and significantly decreased mRNA and protein expressions of Nrf2 and HO-1 （P<0.05， P<0.01）. Compared with the model group， the HYT group manifested significantly reduced serum levels of AST， ALT， and ALP （P<0.05， P<0.01）， significantly reduced contents of MDA and ROS in liver tissue （P<0.01）， significantly increased the activities of SOD and GSH-Px （P<0.01）， significantly decreased mRNA expressions of Keap1， p53， and Caspase-3 （P<0.01）， and significantly increased mRNA and protein expressions of Nrf2 and HO-1 （P<0.05， P<0.01）. ConclusionUnder the condition of 2 times the dose limit of the Pharmacopoeia of the People's Republic of China 2020， Sargassum and Glycyrrhizae Radix et Rhizoma incompatible pair with the HYT on oxidative stress in the liver of goiter rats had different effects. The HYT that contains Sargassum and Glycyrrhizae Radix et Rhizoma has a protective effect on the liver of goiter rats， and the effect is better than that of the HG group， the euthyrox group， and the incomplete groups. Its mechanism may be related to activating the Nrf2/HO-1 signaling pathway to alleviate liver oxidative stress and inhibiting the p53/Caspase-3 signaling pathway to reduce hepatocyte apoptosis.

Objective:To analyze the risk factors for central venous catheter-associated bloodstream infection in patients with emergency hemorrhagic shock.Methods:Patients with hemorrhagic shock and central venous catheterization admitted to the emergency department of Shanghai First People's Hospital from June 2016 to June 2022 were retrospectively analyzed. The patients were divided into infected group and non-infected group according to whether catheter-related bloodstream infection occurred. The puncture site samples and catheter tip samples of infected patients were collected for etiological detection and drug sensitivity test. The difference of baseline data between the two groups was analyzed, and the relationship between central venous catheter-associated infection and influencing factors was analyzed by multivariate logistic regression.Results:A total of 249 patients were included in this study, including 54 patients in the infected group and 195 patients in the non-infected group. There were significant differences in age, catheterization position, ultrasound-guided puncture, acute physiology and chronic health evaluationⅡ(APACHEⅡ) score, catheter retention time and application of broad-spectrum antibiotics between the infected group and the non-infected group (all P<0.05). Multivariate logistic regression analysis showed that advanced age, femoral vein catheterization, no ultrasound-guided puncture, high APACHEⅡ score, long catheter indent time and application of broad-spectrum antibiotics were risk factors for central venous catheter-associated bloodstream infection. Among the 54 infected patients, Staphylococcus epidermidis accounted for 44.4%, followed by Escherichia coli accounted for 24.1% and fungus accounted for 11.1%. The resistance rate of gram-positive cocci to vancomycin was the lowest (3.4%) followed by tetracycline (34.5%), and the highest resistance rate was amoxicillin (100.0%). The resistance rates of gram-negative bacilli to amikacin and ceftriaxone were relatively high, both of which were 94.7%. Conclusions:The risk factors for central venous catheter-related blood stream infection in patients with emergency hemorrhagic shock included advanced age, femoral vein catheterization, no ultrasound-guided puncture, high APACHEⅡ score, long catheter retention time and use of broad-spectrum antibiotics. The common pathogenic bacteria were Staphylococcus epidermidis and Escherichia coli.

ObjectiveTo observe the effect of Hoveniae Semen， Flos Puerariae and their combinations on acute alcoholic liver disease and provide a scientific basis for the drug use in clinical practice and the research on other alcoholic diseases. MethodThe acute alcoholic liver injury model of mice was established by one-time gavage with 56% （V/V） Hongxing Erguotou liquor （12 mL·kg^-1）. One hundred and twenty male ICR mice were randomly assigned into blank group， model group， silybin group， Flos Puerariae group， Hoveniae Semen group， and Flos Puerariae-Hoveniae Semen combination groups （ratios of 1∶1， 1∶2 and 2∶1， respectively）， with 15 mice in each group. Each group was administrated with 10 mL·kg^-1 corresponding preventive drugs for 3 days by gavage. Except the blank group， the other groups were given Erguotou liquor by gavage at 12 mL·kg^-1. The mice were sacrificed 12 h after drinking for the observation of liver function and oxidative stress. The pathological changes of liver were observed via hematoxylin-eosin （HE） staining. Western blot was employed to determine the expression levels of proteins in the Kelch-like Ech-associated protein 1 （Keap1）/nuclear factor E₂-related factor 2 （Nrf2）/antioxidant response element （ARE） signaling pathway. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to detect mRNA levels of related genes. ResultCompared with control group， the modeling elevated the levels of alanine aminotransferase （ALT）， aspartate aminotransferase （AST） and alkaline phosphatase （ALP） in the serum and the content of malondialdehyde （MDA） and reactive oxygen species （ROS） in liver tissue （P<0.01） and decreased the activities of glutathione （GSH） and superoxide dismutase （SOD） （P<0.01）. The mRNA and protein expressions of Keap1 were significantly increased （P<0.05，P<0.01）， mRNA and protein expressions of Nrf2 were significantly decreased （P<0.01）. Compared with model group， Flos Puerariae-Hoveniae Semen 2∶1 lowered the levels of ALT， AST and ALP in the serum （P<0.01） and MDA and ROS in the liver （P<0.01）， and increased the activities of GSH and SOD （P<0.01）. Moreover， it alleviated the hepatic steatosis injury， up-regulated mRNA and protein levels of Nrf2 （P<0.01）， and down-regulated the mRNA and protein levels of Keap1 （P<0.01）. ConclusionFlos Puerariae， Hoveniae Semen and their combinations may exert the pre-protective effect on acute alcoholic liver injury in mice by regulating the Keap1/Nrf2/ARE pathway in the liver and restoring the liver oxidative balance destroyed by ethanol to inhibit the development of alcoholic liver disease .

Primary endometrioid adenocarcinoma of the rectovaginal septum is rare. Its pathogenesis is not clear and there is no standard treatment. One patient with endometrioid adenocarcinoma of the rectovaginal septum arising from deep infiltrative endometriosis was admitted to Qingdao Municipal Hospital. The patient presented with incessant menstruation and abdominal distension. She had bilateral ovarian endometriotic cystectomy 6 years ago. Imaging findings suggested a pelvic mass which might invade the rectovaginal septum. Pathological results of primary surgery confirmed endometrioid carcinoma of the pelvic mass arising from the rectovaginal septum. Then she had a comprehensive staged surgery. Postoperative chemotherapy was given 6 times. No recurrence or metastasis was found during the 2-year follow-up. The possibility of deep infiltrating endometriosis and its malignant transformation should be considered in the differential diagnosis of a new extragonadal pelvic lesion in a patient with a history of endometriosis, which would avoid misdiagnosis and missed diagnosis.

It aims to provide the clinicians and vaccination professionals with guidelines on using rBS/WC vaccine to reduce the incidence of ETEC infectious diarrhea.

OBJECTIVES: The aim of this study was to evaluate the disease burden of prostate cancer (PC) and assess key influencing factors associated with the disease expenditures of PC in the United States. METHODS: The total deaths, incidence, prevalence, and disability-adjusted life-years of PC were obtained from the Global Burden of Disease Study 2019. The Medical Expenditure Panel Survey was used to estimate healthcare expenditures and productivity loss and to investigate patterns of payment and use of healthcare resources in the United States. A multivariable logistic regression model was conducted to identify key factors influencing expenditures. RESULTS: For patients aged 50 and older, the burden for all age groups showed a modest increase over the 6-year period. Annual medical expenditures were estimated to range from US$24.8 billion to US$39.2 billion from 2014 to 2019. The annual loss in productivity for patients was approximately US$1,200. The top 3 major components of medical costs were hospital inpatient stays, prescription medicines, and office-based visits. Medicare was the largest source of payments for survivors. In terms of drug consumption, genitourinary tract agents (57.0%) and antineoplastics (18.6%) were the main therapeutic drugs. High medical expenditures were positively associated with age (p=0.005), having private health insurance (p=0.016), more comorbidities, not currently smoking (p=0.001), and patient self-perception of fair/poor health status (p<0.001). CONCLUSIONS From 2014 to 2019, the national real-world data of PC revealed that the disease burden in the United States continued to increase, which was partly related to patient characteristics.

Objective:To explore the clinical and CT imaging features of immune checkpoint inhibitor-associated pneumonia (CIP) and to improve the early diagnostic ability of CIP.Methods:From June 1, 2020 to October 31, 2021, the clinical data and chest CT images of 2 067 patients with advanced malignant tumor treated with immune checkpoint inhibitor (ICI) in the First Medical Center, Chinese PLA General Hospital were retrospectively analyzed. Patients with CIP were enrolled according to the guidelines for CIP diagnosis, and the incidence, time from the start of medication to the onset of CIP, medication cycle, imaging features, imaging patterns, CT grade and outcomes were analyzed. χ 2 test was used to compare the incidence of CIP in patients with or without basic lung disease. Results:Among 2 067 patients with malignant tumors treated with ICI, 67 patients developed CIP, the incidence of CIP was 3.2%. The incidence of CIP was significantly different between 386 patients with basic lung disease (7.00%, 27/386) and 1 681 patients without basic lung disease (2.4%, 40/1 681) (χ 2=21.32, P<0.001). The time from the start of medication to the onset of CIP was 7-367 d (median 52 days), and the duration of medication was 1-12 cycles (median 2 cycles). The imaging features of CIP presented as ground glass opacities in 54 cases (80.6%), solid nodules in 26 cases (38.8%), consolidations in 25 cases (37.3%) and irregular reticular opacities in 24 cases (35.8%). The main radiologic pattern was organizing pneumonia (OP, 34 cases, 50.7%), and followed by diffuse alveolar damage (DAD) pattern (14 cases, 20.9%). According to CT grading, there were 26 cases in low risk grade, 17 cases in moderate risk grade and 24 cases in high risk grade. Of 43 low-and medium-risk grade cases, 25 were OP pattern, accounting for 58.1%, and among 24 high-risk grade patients, 13 were DAD pattern, accounting for 54.2%. Forty-three of the 52 patients were initially untreated, of which 23 patients progressed, 17 had lesion shrinkage, and 3 had resolution, and relapsed in 8 cases after resolution or drug withdrawal. Conclusions:The imaging manifestations of CIP are mainly ground glass opacities, nodules, consolidations, and irregular reticular opacities. The radiologic patterns are mainly OP and DAD. OP is the most common pattern in low-moderate risk grade CIP and DAD is the most common pattern in high risk grade CIP. Patients with basic lung disease are more likely to get CIP.

Objective:To study the use of primary continuous single-layer pancreaticojejunostomy after linear stapler closure of pancreatic neck in pancreaticoduodenectomy (PD).Methods:The clinical data of 21 patients who were treated with primary continuous single-layer pancreaticojejunostomy after linear stapler closure of pancreatic neck in PD at Beijing Chaoyang Hospital Affiliated, West Campus, Capital Medical University, Rizhao Hepatobiliary-pancreatic-splenic Surgery Research Institute, Binzhou Second People’s Hospital, Chaoyang Central Hospital from February 2022 to May 2022 were retrospectively analyzed. There were 12 males and 9 females, with ages ranging from 31.0 to 82.0 years (median age 63.0 years). The success rates of linear stapling at pancreatic neck, time of pancreaticojejunostomy, postoperative complications, pancreatic fistula risk score, and length of hospital stay were studied.Results:Among the 21 patients, there were 3 patients who underwent open PD and 18 patients who underwent laparoscopic PD. Primary continuous single-layer pancreaticojejunostomy after linear stapler closure of pancreatic neck was successfully carried out in all these patients. The success rate was 100.0%. The success rate of finding pancreatic ducts at the pancreatic stumps and inserting an drainage tube was 100.0%(21/21). In the 3 patients who underwent open PD, the operation time were 230.0, 245.0 and 250.0 minutes respectively. The time for completing pancreaticojejunostomy were 12.0, 13.0 and 12.0 minutes respectively. The estimated blood loss were 300.0, 450.0 and 600.0 ml respectively. The length of hospital stay were 14.0, 15.0 and 21.0 days. In the 18 patients who underwent laparoscopic PD, the operation time was (295.9±14.5) min, the time for constructing pancreaticojejunostomy was (22.3±1.5) min, the blood loss was (180.0±40.0) ml, the length of hospital stay ranging from 8.0 to 16.0 days (median 10.5 days). Among all the 21 patients, the pancreatic fistula risk score was (4.7±1.5). Postoperative acute pancreatitis occurred in 3 patients (14.3%), delayed gastric emptying occurred in 4 patients (19.0%), and all of them recovered after conservative treatment. There was no postoperative bleeding, nosocomial infection, grade B and C postoperative pancreatic fistula or perioperative death.Conclusion:The continuous single-layer pancreaticojejunostomy after linear stapler closure of the pancreatic neck was safe, reliable, simple and technically easy. It has the potential to prevent clinical postoperative pancreatic fistula and pancreaticojejunostomy bleeding. It is worth to popularize this surgical procedure.

Aiming at the problems of individual differences in the asynchrony process of human lower limbs and random changes in stride during walking, this paper proposes a method for gait recognition and prediction using motion posture signals. The research adopts an optimized gated recurrent unit (GRU) network algorithm based on immune particle swarm optimization (IPSO) to establish a network model that takes human body posture change data as the input, and the posture change data and accuracy of the next stage as the output, to realize the prediction of human body posture changes. This paper first clearly outlines the process of IPSO's optimization of the GRU algorithm. It collects human body posture change data of multiple subjects performing flat-land walking, squatting, and sitting leg flexion and extension movements. Then, through comparative analysis of IPSO optimized recurrent neural network (RNN), long short-term memory (LSTM) network, GRU network classification and prediction, the effectiveness of the built model is verified. The test results show that the optimized algorithm can better predict the changes in human posture. Among them, the root mean square error (RMSE) of flat-land walking and squatting can reach the accuracy of 10 ^-3, and the RMSE of sitting leg flexion and extension can reach the accuracy of 10 ^-2. The R ² value of various actions can reach above 0.966. The above research results show that the optimized algorithm can be applied to realize human gait movement evaluation and gait trend prediction in rehabilitation treatment, as well as in the design of artificial limbs and lower limb rehabilitation equipment, which provide a reference for future research to improve patients' limb function, activity level, and life independence ability.
