Hyperkalemia is one of the common ion metabolism disorders in clinical practice. Hyperkalemia is defined as serum potassium higher than 5.0 mmol/L according to the guidelines at home and abroad. Acute severe hyperkalemia can cause serious consequences, such as flaccid paralysis, fatal arrhythmia, and even cardiac arrest. The use of renin-angiotensin- aldosterone system inhibitors, β-blockers and diuretics, low-sodium and high-potassium diets, and the presence of related comorbidities increase the occurrence of hyperkalemia. Hyperkalemia risk exist in all clinical departments, but there is a lack of a standardization in the management of multi- department cooperation in hospital. Therefore, a number of domestic nephrology and cardiology department experts have discussed a management model for multi-department cooperation in hyperkalemia, formulating the management standard on hospital evaluation, early warning, diagnosis and treatment, and process. This can promote each department to more effectively participate in nosocomial hyperkalemia diagnosis and treatment, as well as the long-term management of chronic hyperkalemia, improving the quality of hyperkalemia management in hospital.

AIM To investigate the variation rules of main secondary metabolites in Hedysari Radix before and after rubbing strip.METHODS UPLC-MS/MS was adopted in the content determination of formononetin,ononin,calycosin,calycosin-7-glucoside,medicarpin,genistein,luteolin,liquiritigenin,isoliquiritigenin,vanillic acid,ferulic acid,γ-aminobutyric acid,adenosine and betaine,after which cluster analysis,principal component analysis and orthogonal partial least squares discriminant analysis were used for chemical pattern recognition to explore differential components.RESULTS After rubbing strip,formononetin,calycosin,liquiritigenin and γ-aminobutynic acid demonstrated increased contents,along with decreased contents of ononin,calycosin-7-glucoside and vanillic acid.The samples with and without rubbing strip were clustered into two types,calycosin-7-glucoside,formononetin,γ-aminobutynic acid,vanillic acid,calycosin-7-glucoside and formononetin were differential components.CONCLUSION This experiment clarifies the differences of chemical constituents in Hedysari Radix before and after rubbing strip,which can provide a reference for the research on rubbing strip mechanism of other medicinal materials.

Objective: To describe the prevalence of alcohol consumption and the burden of hemorrhagic stroke and hypertensive heart disease attributed to alcohol consumption in adults aged ≥20 years in 31 provinces in China from 2005 to 2018. Methods: Data from several national representative surveys was used to estimate provincial alcohol exposure level of adults aged ≥20 years from 2005 to 2018 by using kriging interpolation and locally weighted regression methods. Global disease burden research method and data, and China's death cause surveillance data were used to calculate the population attributable fraction (PAF) of hemorrhagic stroke and hypertensive heart disease and the deaths due to alcohol consumption in men and women aged ≥20 years in 31 provinces in China. China census data of 2010 were used to calculate the attributable standardized mortality rate. Results: In 2005 and 2018, the prevalence of alcohol consumption was 58.7% (95%CI: 57.8%-59.5%) and 58.4% (95%CI: 57.6%-59.3%), respectively, in men and 17.0% (95%CI: 16.6%-17.4%) and 18.7% (95%CI:18.1%-19.3%), respectively, in women. The daily alcohol intake was 24.6 (95%CI: 23.8-25.3) g and 27.7 (95%CI: 26.8-28.7) g, respectively, in men and 6.3 (95%CI: 6.0-6.5) g and 5.3 (95%CI: 5.0-5.6) g, respectively, in women. Alcohol exposure level was higher in the provinces in central and eastern China than in western provinces. The lowest exposure level was found in northwestern provinces. From 2005 to 2018, the PAF of hemorrhagic stroke death due to alcohol consumption increased from 5.5% to 6.8%, the attributable deaths increased from 50 200 to 59 100, while the PAF of hypertensive heart disease death due to alcohol consumption increased from 7.0% to 7.7%, the attributable deaths increased from 15 200 to 29 300. The PAF of hypertensive heart disease and hemorrhagic stroke was higher in men than in women, and in central and eastern provinces than in western provinces. In 2018, the standardized mortality rates of hemorrhagic stroke and hypertensive heart disease attributed to alcohol consumption were 4.58/100 000 and 2.11/100 000, respectively. Conclusions: The prevalence of alcohol consumption in men and daily alcohol intake of drinkers were relatively high in China, especially in eastern provinces. Alcohol exposure level was lower in women than in men. Regional measures should be taken to reduce the alcohol intakes in men and current drinkers in order to reduce the health problems caused by alcohol consumption.

Objective:To establish donor liver quality related risk factors for the loss of function of transplanted liver.Methods:The data of donors and recipients of liver transplantation at the Organ Donation and Transplantation Center of the First Affiliated Hospital of Sun Yat-sen University from Nov 2011 to Dec 2018 were analyzed retrospectively. Propensity score matching (PSM) was performed to evaluate and screen the data of donors and recipients, in order to balance the covariates.Results:Of the organ donation, there were 70 males and 20 females , aging (40.6±16.3) years. Of the liver transplantation recipients, there were 70 males and 20 females , aging (41.8±20.3) years. Liver dysfunction after transplantation was significantly correlated with the following variables: the donor's CPR time( t=0.429, P=0.000), 15-minute retention rate of indocyanine green ( χ2=67.151, P=0.000), liver function grading ( χ2=54.154, P=0.000), bullae fatty liver grading ( χ2=8.120, P=0.017), vesicular fatty liver grading ( χ2=16.000, P=0.001), ICU stay time ( χ2=14.900, P=0.001)and serum creatinine level ( χ2=44.685, P=0.000). The donor scoring system was established in our studying. For the 90 organ donation cases, the donated liver quality were classified into four levels,which were of good correspondence to the prognosis of the recipients. Conclusion:This donor scoring system and grading standards established by analyzing the high-risk factors of liver dysfunction after transplantation helps evaluate the quality of donor liver in China.

Chest trauma is one of the most common injuries. Venous thromboembolism (VTE) as a common complication of chest trauma seriously affects the quality of patients′ life and even leads to death. Although there are some consensus and guidelines on the prevention and treatment of VTE at home and abroad, the current literatures lack specificity considering the diagnosis, treatment and prevention of VTE in patients with chest trauma have their own characteristics, especially for those with blunt trauma. Accordingly, China Chest Injury Research Society and editorial board of Chinese Journal of Traumatology organized relevant domestic experts to jointly formulate the Chinese expert consensus on the diagnosis, treatment and prevention of chest trauma venous thromboembolism associated with chest trauma (2022 version). This consensus provides expert recommendations of different levels as academic guidance in terms of the characteristics, clinical manifestations, risk assessment, diagnosis, treatment, and prevention of chest trauma-related VTE, so as to offer a reference for clinical application.

Objective: To explore the effect of perioperative chemotherapy on the prognosis of gastric cancer patients under real-world condition. Methods: A retrospective cohort study was carried out. Real world data of gastric cancer patients receiving perioperative chemotherapy and surgery + adjuvant chemotherapy in 33 domestic hospitals from January 1, 2014 to January 31, 2016 were collected. Inclusion criteria: (1) gastric adenocarcinoma was confirmed by histopathology, and clinical stage was cT2-4aN0-3M0 (AJCC 8th edition); (2) D2 radical gastric cancer surgery was performed; (3) at least one cycle of neoadjuvant chemotherapy (NAC) was completed; (4) at least 4 cycles of adjuvant chemotherapy (AC) [SOX (S-1+oxaliplatin) or CapeOX (capecitabine + oxaliplatin)] were completed. Exclusion criteria: (1) complicated with other malignant tumors; (2) radiotherapy received; (3) patients with incomplete data. The enrolled patients who received neoadjuvant chemotherapy and adjuvant chemotherapy were included in the perioperative chemotherapy group, and those who received only postoperative adjuvant chemotherapy were included in the surgery + adjuvant chemotherapy group. Propensity score matching (PSM) method was used to control selection bias. The primary outcome were overall survival (OS) and progression-free survival (PFS) after PSM. OS was defined as the time from the first neoadjuvant chemotherapy (operation + adjuvant chemotherapy group: from the date of operation) to the last effective follow-up or death. PFS was defined as the time from the first neoadjuvant chemotherapy (operation + adjuvant chemotherapy group: from the date of operation) to the first imaging diagnosis of tumor progression or death. The Kaplan-Meier method was used to estimate the survival rate, and the Cox proportional hazards model was used to evaluate the independent effect of perioperative chemo therapy on OS and PFS. Results: 2 045 cases were included, including 1 293 cases in the surgery+adjuvant chemotherapy group and 752 cases in the perioperative chemotherapy group. After PSM, 492 pairs were included in the analysis. There were no statistically significant differences in gender, age, body mass index, tumor stage before treatment, and tumor location between the two groups (all P>0.05). Compared with the surgery + adjuvant chemotherapy group, patients in the perioperative chemotherapy group had higher proportion of total gastrectomy (χ(2)=40.526, P<0.001), smaller maximum tumor diameter (t=3.969, P<0.001), less number of metastatic lymph nodes (t=1.343, P<0.001), lower ratio of vessel invasion (χ(2)=11.897, P=0.001) and nerve invasion (χ(2)=12.338, P<0.001). In the perioperative chemotherapy group and surgery + adjuvant chemotherapy group, 24 cases (4.9%) and 17 cases (3.4%) developed postoperative complications, respectively, and no significant difference was found between two groups (χ(2)=0.815, P=0.367). The median OS of the perioperative chemotherapy group was longer than that of the surgery + adjuvant chemotherapy group (65 months vs. 45 months, HR: 0.74, 95% CI: 0.62-0.89, P=0.001); the median PFS of the perioperative chemotherapy group was also longer than that of the surgery+adjuvant chemotherapy group (56 months vs. 36 months, HR=0.72, 95% CI:0.61-0.85, P<0.001). The forest plot results of subgroup analysis showed that both men and women could benefit from perioperative chemotherapy (all P<0.05); patients over 45 years of age (P<0.05) and with normal body mass (P<0.01) could benefit significantly; patients with cTNM stage II and III presented a trend of benefit or could benefit significantly (P<0.05); patients with signet ring cell carcinoma benefited little (P>0.05); tumors in the gastric body and gastric antrum benefited more significantly (P<0.05). Conclusion: Perioperative chemotherapy can improve the prognosis of gastric cancer patients.

Objective: To explore the diagnosis and clinical features of internal carotid artery aneurysm in the skull base. Methods: The data of 15 patients with internal carotid aneurysms in the skull base diagnosed and treated by digital subtraction angiography (DSA) or CT angiography (CTA) in the Provincial Hospital Affiliated to Shandong First Medical University from 1995 to 2017 were collected and analyzed. Among the 15 patients, 12 were males, and 3 were females, aging from 17 to 67 years old, with a median age of 44 years. Thirteen patients were diagnosed by DSA; the other two patients were diagnosed by CTA. Thirteen patients were diagnosed with pseudoaneurysm with the first symptom of epistaxis, in which eight patients underwent head trauma and 5 underwent radiotherapy of skull base tumor. The other two patients were diagnosed with true aneurysm presented headache and cranial nerve disorder. All patients were followed up for 2 to 12 years after treatment to see whether they were cured and survived. Results: Among the eight patients with a history of trauma, five patients were cured by embolization, two patients without embolization died of massive epistaxis, one patient died of progressive cerebral infarction after embolization. Among the five patients with radiotherapy of skull base tumor, one patient died of cerebral infarction after embolization, two patients died out of the hospital due to the recurrence of the primary tumor and intracranial invasion, one patient recovered well after embolization and surgical operation, one patient gave up treatment and died of massive hemorrhage out of hospital. In the other two patients with symptom of headache, one received embolization treatment outside the hospital after receiving mistake operation, and another one gave up treatment and died due to personal reasons. In total, four patients died in hospital, four died out of the hospital, and seven patients survived. Conclusions: Internal carotid artery aneurysm is a high-risk disease of anterior and middle skull base. For patients with epistaxis with a history of trauma and radiotherapy or patients with headaches and cranial nerve disorders, the possibility of the internal carotid artery aneurysm should be considered, in which DSA or CTA examination is essentially required for ensured diagnosis and disease evaluation.. The correct diagnosis and treatment by the otolaryngologist are crucial to the prognosis of the patient.

Objective: To indicate the clinical features of endoscopic transnasal resection of epidural cholesteatoma at paracentral skull base and to analyze its efficacy. Methods: The total excision rate, postoperative complications and postoperative curative effect of 7 patients (4 males and 3 females, aging from 32 to 63 years old) who underwent middle skull base surgery for epidural cholesteatoma resection under transnasal endoscope at Tianjin Huanhu Hospital between August 2017 and August 2020 were retrospectively reviewed. All patients were followed up for 6 to 36 months. The postoperative MRI, clinical symptoms and recurrence were reviewed. Descriptive statistical methods were used for analysis. Results: Among the 7 patients, there were total resection (complete resection of cyst contents and capsule) in 4 patients, near-total resection (complete resection of cyst contents, incomplete resection of cyst capsule) in 1 patient, and subtotal resection (incomplete resection of cyst contents and capsule) in 2 patients. The clinical symptoms of all patients were improved postoperatively with 1 patient who had no clinical symptoms. One case had postoperative cerebrospinal fluid rhinorrhea, which was cured after lumbar drainage and nasal iodoform gauge packing. Up to now, 7 patients (including patients with partial resection) had no recurrence. Conclusion: Endoscopic transnasal approaches may be effectively used for resection of epidural cholesteatoma in the paracentral skull base in carefully selected cases.
