Standardizing the emergency assessment and management process for patients with implantable continuous-flow left ventricular assist device (LVAD) in emergency and intensive care settings is of great significance for reducing delays in diagnosis and treatment, lowering the mortality associated with LVAD-related emergencies, and improving overall prognosis and long-term survival. To this end, a multidisciplinary expert committee was convened to develop this consensus, integrating international evidence-based findings with clinical practice experience in China, with an emphasis on highlighting the characteristics of domestically manufactured devices. The aim is to establish an actionable standardized emergency management protocol to enhance clinical identification and response efficiency, reduce the risk of LVAD-related emergencies, and improve patient outcomes. Using a modified Delphi method, this consensus proposes a structured decision-making pathway that integrates an "ABC" rapid assessment with parallel device troubleshooting, prioritizing the use of point-of-care echocardiography for hemodynamic evaluation and complication assessment. Key emergency scenarios covered include low-flow alarms, pump thrombosis, right heart dysfunction, bleeding and anticoagulation imbalance, arrhythmias, and cardiac arrest. This consensus applies to implantable continuous-flow LVADs commonly used in China, including domestically manufactured devices such as Corheart 6, CH-VAD, EVAHEART, and HeartCon, as well as the imported device HeartMate 3.

Objective To investigate the influence of ultrasound-guided bilateral quadratus lumborum-pudendal nerve block combined with general anesthesia on analgesic effect after laparoscopic radical resection of colorectal cancer.Methods A total of 76 patients with laparoscopic radical resection of colorectal cancer from January 2025 to May 2025 were included.By using the single-double number method,they were divided into block general anesthesia group(double number,n=38)and conventional general anesthesia group(single number,n=38).The block general anesthesia group was treated with ultrasound-guided bilateral quadratus lumborum-pudendal nerve block combined with general anesthesia,while the conventional general anesthesia group was given conventional general anesthesia regimen.The anesthesia recovery indexes,hemodynamic indexes[heart rate(HR),mean arterial pressure(MAP),and saturation of peripheral oxygen(SpO2)]before anesthesia,at the time of skin incision,skin suture,and the end of surgery,as well as the Visual Analogue Scale(VAS)score of pain at rest and activity and Riker Sedation-Agitation Scale score at 3,12,24,and 48 h after surgery,and levels of inflammatory factors and pain stress indexes before surgery and at 24 h after surgery were compared between the two groups.The adverse anesthesia reactions in the two groups were observed.Results The remifentanil dosage,sufentanil dosage,agitation rate,general anesthesia recovery time,first exhaust time,and remedial analgesia utilization rate in the block general anesthesia group were significantly lower or shorter than those in the conventional general anesthesia group(P<0.05).The HR and MAP were lower in the block general anesthesia group than those in the conventional general anesthesia group at the time of skin incision,skin suture,and the end of surgery(P<0.05),and there was no significant difference in SpO2(P>0.05).The VAS scores at rest and activity in the block general anesthesia group at 3,12,and 48 h after surgery were lower than those in the conventional general anesthesia group(P<0.05),and the Riker Sedation-Agitation Scale scores at 24 and 48 h after surgery were lower than those in the conventional general anesthesia group(P<0.05).At 24 h after surgery,the levels of interleukin-6,cortisol,and adrenocorticotropic hormone in the block general anesthesia group were lower than those in the conventional general anesthesia group(P<0.05).The total incidence rates of adverse anesthesia reactions in the block general anesthesia group[7.9%(3/38)]was significantly lower than that in the conventional general anesthesia group[26.3%(10/38),P=0.033].Conclusions The application of ultrasound-guided bilateral quadratus lumborum-pudendal nerve block combined with general anesthesia during laparoscopic radical resection of colorectal cancer has good analgesic and sedative effects.It has small influence on hemodynamics,reduces the dosages of opioids,relieves the inflammatory stress response,and reduces the adverse reactions.

Pancreatic cancer is also known as the " king of cancer" . It is difficult to diagnose and has a high degree of malignancy. Most patients are in advanced stage when they are found. The prognosis is very poor. Early diagnosis and treatment of pancreatic cancer are very important to improve survival rate and prognosis. In recent years, with the continuous popularization of laparoscopic technology, as well as the updating and iteration of related equipment such as 3D visualization and 4K high-definition laparoscopy, and the continuous maturity of surgical technology, laparoscopic surgery for pancreatic tumors has also made unprecedented progress. This review will discuss the application and development of laparoscopic pancreatic surgery as a treatment strategy for pancreatic cancer based on the existing research progress.

BACKGROUND: Extreme temperature events, including extreme cold, are becoming more frequent worldwide, which might be harmful to pregnant women and cause adverse birth outcomes. We aimed to investigate the association between exposure to low ambient temperature in pregnant women and adverse birth outcomes, such as preterm birth, low birth weight, and stillbirth, and to summarize the evidence herein. METHODS: Relevant studies were searched in PubMed, Cochrane, and Embase electronic databases until November 2021. Studies involving low ambient temperature, preterm birth, birth weight, and stillbirth were included. The guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-analyses were followed to conduct this study risk of bias and methods for data synthesis. RESULTS: A total of 34 studies were included. First, pregnant women exposed to low ambient temperature had an increased risk of preterm birth (risk ratio [RR] 1.08; 95% confidence interval [CI] 1.04-1.13). Subgroup analyses revealed that exposure during late pregnancy was more likely to induce preterm birth. In addition, only pregnant women exposed to <1st percentile of the mean temperature suffered increased risk of preterm birth. Moreover, pregnant women living in medium or hot areas were more prone to have preterm births than those in cold areas when exposed to low ambient temperatures. Asians and Blacks were more susceptible to low ambient temperatures than Caucasians. Second, pregnant women exposed to low ambient temperature had an increased risk of low birth weight (RR 1.07; 95% CI 1.03-1.12). Third, pregnant women had an increased risk of stillbirth while exposed to low ambient temperature during the entire pregnancy (RR 4.63; 95% CI 3.99-5.38). CONCLUSIONS: Exposure to low ambient temperature during pregnancy increases the risk of adverse birth outcomes. Pregnant women should avoid exposure to extremely low ambient temperature (<1st percentile of the mean temperature), especially in their late pregnancy. This study could provide clues for preventing adverse outcomes from meteorological factors. REGISTRATION No. CRD42021259776 at PROSPERO ( https://www.crd.york.ac.uk/PROSPERO/ ).

BACKGROUND: Epilepsy accounts for a significant portion of the global disease burden. However, little is known about the disease burden of epilepsy in China and its provinces. METHODS: We assessed the burden of epilepsy in China and its provinces, municipalities, and autonomous regions from 1990 to 2019. Burden was measured as incidence, prevalence, deaths, years lived with disability, years of life lost, and disability-adjusted life years (DALYs), by age, sex, year, and province. We used the Socio-Demographic Index (SDI) to determine the association between the provincial development level and age-standardized DALY rates of epilepsy from 1990 to 2019. RESULTS: In 2019, epilepsy caused 1367.51 thousand (95% uncertainty interval [UI]: 979.92-1837.61 thousand) DALYs, and the age-standardized DALY rate was 99.77 (95% UI: 71.33-133.52)/100,000. The age-standardized incidence and prevalence rates for epilepsy in China were 24.65/100,000 and 219.69/100,000, increased by 45.00% (95% UI: 8.03-98.74%) and 35.72% (95% UI: 0.47-86.19%) compared with that in 1990, respectively. From 1990 to 2019, the proportion of DALY caused by epilepsy in the age group under 25 years steadily decreased. The proportion of DALYs caused by epilepsy in people aged 50 years and over increased from 9.45% and 10.22% in 1990 to 29.01% and 32.72% for male and female individuals in 2019, respectively. The highest age-standardized mortality rates were seen in Tibet (4.26 [95% UI: 1.43-5.66]/100,000), Qinghai (1.80 [95% UI: 1.15-2.36]/100,000), and Yunnan (1.30 [95% UI: 0.88-1.62]/100,000), and the lowest mortality rates were in Guangdong (0.48 [95% UI: 0.39-0.64]/100,000), Zhejiang (0.56 [95% UI: 0.44-0.70]/100,000), and Shanghai (0.57 [95% UI: 0.41-0.73]/100,000). The age-standardized DALY rates across the country and in provinces, municipalities, and autonomous regions generally decreased as their SDI increased. CONCLUSIONS The disease burden of epilepsy is still heavy in China, especially in the western provinces. The incidence and prevalence of epilepsy increased between 1990 and 2019, and the burden of epilepsy in the elderly increases gradually. This study provides evidence on epilepsy prevention and care of different regions in China.

Objective: To evaluate the value of Kirschner wire internal fixation in the treatment of sagittal mandibular condylar fractures. .Methods : From January 2019 to January 2020, 13 patients (19 sides) with mandibular condylar sagittal fracture treated by Kirschner wire internal fixation at the Stomatological Medical Center, Foshan Hospital of Traditional Chinese Medicine were retrospectively analyzed. After conventional surgical incision and exposure and reduction of the mandibular condyle, 2-4 Kirschner wires were used for fixation, and other maxillofacial fractures were treated simultaneously. The reduction accuracy and stability of the free mandibular condyle were evaluated by CBCT one week after the operation, and the occlusion relationship, opening degree and opening type were evaluated by clinical examination. Results: All patients had good fracture alignment and no twisting, breaking or loosening of the Kirschner wire. The occlusion relationship, opening degree and opening shape recovered well after the operation. Conclusion Kirschner wire is effective in treating sagittal fractures of mandibular condyles.

Objective:To study and analyse the results of postoperative hemorrhage after laparoscopic pancreaticoduodenectomy (LPD).Methods:The clinical data of patients who underwent LPD from May 2011 to December 2019 at Hunan Provincial People's Hospital were retrospectively analyzed. The clinical characteristics of patients, onset time of postoperative hemorrhage, location of postoperative hemorrhage, postoperative biliary fistula, pancreatic fistula, infection and other short-term complications, reoperation and mortality rates were analyzed.Results:Of 356 patients who underwent LPD in this study, there were 200 males and 156 females, aged (58.0±10.5) years. The postoperative complication rate was 33.1% (118/356), the reoperation rate was 6.5% (23/356), and the mortality rate was 2.5% (9/356). The most common complications were postoperative hemorrhage [15.2% (54/356)], pancreatic fistula [14.6%(52/356)] and abdominal infection [13.8%(49/356)]. The onset time of postoperative hemorrhage was usually in the 1st - 14th day, and the highest rate of postoperative hemorrhage was 3.9% (14/356) on the first day after surgery. The postoperative hemorrhage rate then showed a downward trend, but increased again on the 7th day. The extraluminal hemorrhage locations were relatively widely distributed, and the incidence of gastrointestinal anastomotic hemorrhage in patients with intraluminal hemorrhage was the highest [67.9%(19/28)]. Of the 9 patients who died, 7 were related to postoperative bleeding.Conclusions:LPD resulted in a high incidence of complications. Postoperative hemorrhage was a complication that had the greatest impact on short-term recovery of patients. It was also an important cause of reoperation and death. In addition to postoperative bleeding caused by pancreatic fistula, gastrointestinal anastomotic bleeding was also clinically important.

Objective: To explore a predictive model for outcomes of severe acute pancreatitis (SAP) patients. Methods: A retrospective study was conducted of 102 SAP patients from January 1,2016 to April 30,2018 from Taizhou Hospital in this study. The participants were divided into survival group and death group according to the outcome of 90 days after admission,88 cases were in survival group including 57 males and 31 females, aged 55.5 (40.3-69.8) years; 14 cases were in death group including 5 males and 9 females, aged 63.0 (50.8-80.8) years. Clinical data and laboratory indicators were compared between the two groups. Statistical analyses were performed to compare categorical variables. Chi-square automatic interaction detector (CHAID) was used to construct the prediction model of SAP patients′ outcomes. The study cohort consisted of SAP patients from August 1st 2018 to July 1st 2019 were collected to validate the prediction model. Results: (1)Statistical analyses were performed by chi square test and Mann-Whitney U test. There were statistically significant differences in the proportion of cardiovascular and cerebrovascular diseases, mechanical ventilation and septic shock, and also the Charlson complication index (CCI), the Ranson score and APACHEⅡscore(χ²=5.554, P=0.018; χ²=5.585,P=0.018;P=0.008;Z=-3.007,P=0.003;Z=-2.982, P=0.003; Z=-3.257, P=0.001), death group were higher than survival group. (2) The MPV, CRP, MCHC, pH, pCO2 and positive rates of NRBC were statistically different between survival group and death group(Z=-2.466,P=0.014;Z=-2.689,P=0.007;Z=-2.238,P=0.025;Z=-1.977,P=0.048;Z=-2.239, P=0.025;P=0.000).The NRBC-positive rate in the death group was higher than that in the survival group, while the other indexes were lower in the survival group.(3)The decision tree CHAID method obtains the prediction scheme: when it meets the Ranson score≤3, the SAP patients were judged to be alive; when it meets the Ranson score>3 and the NRBC in peripheral blood was negative, the SAP patients were judged to be alive; when it meets the Ranson score>3, the NRBC was positive and the APACHEⅡscore≤21, the SAP patients were judged to be alive; when it meets the Ranson score>3, NRBC was positive and APACHE Ⅱ>21, the SAP patients were adverse prognosis. (4) 50 SAP patients were collected in the validation group, with 43 actual survivors and 7 deaths. The accuracy rate of predicting the outcomes of SAP patients in validation group with the scheme was 94.0% (47/50). Conclusion The NRBC combined with Ranson score system and APACHE II score system can predict the outcomes of SAP patients.

Objective: To investigate the application value of real-time virtual sonography(RVS)in the diagnosis and treatment of complicated hepatolithiasis. Methods: The retrospective and descriptive study was conducted. The clinical data of 10 patients with complicated hepatolithiasis who were admitted to Hunan Provincial People′s Hospital between October 2017 and March 2018 were collected. There were 3 males and 7 females, aged from 40 to 69 years, with an average age of 57 years. Patients received abdominal color Doppler ultrasound examination, magnetic resonance cholangiopancreatography, and upper abdominal spiral computed tomography (CT) thinly scanning + enhanced examination. Data of CT examination were imported into RVS. RVS was used to locate hepatolithiasis, relationship between stones and vessels, anatomy of bile ducts and vessels in hepatic hilus. Surgical methods included RVS-guided hilar cholangiotomy, biliary stricturoplasty, bilateral hepatojejunostomy, hepatic segmentectomy (lobectomy), and hepatolithotomy. Observation indicators: (1) surgical and postoperative situations; (2) typical case analysis; (3) follow-up. Follow-up using outpatient examination was performed to detect residual stones up to June 2019. Measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers. Results: (1) Surgical and postoperative situations: 10 patients underwent RVS-guided surgeries successfully for complicated hepatolithiasis, with successful match in RVS (difference between CT images and ultrosound images <2 mm). No residual stone was identified by choledochoscope during operation. The operation time and volume of intraoperative blood loss were 285 minutes (range, 210-360 minutes) and 200 mL (range, 100-600 mL), respectively. No blood transfusion was needed during the operations. The duration of hospital stay was 20.5 days (range, 14.0-29.0 days). There was no perioperative death. One patient had postoperative biliary leakage and abdominal infection, and was cured after conservative treatment. (2) Typical case analysis: the tenth patient, female, 60 years old, was diagnosed with complicated hepatolithiasis, and was prepared to undergo hepatolithotomy+ quadrate lobectomy and hilar cholangioplasty+ bilateral hepatojejunostomy. Preoperative CT images and intraoperative color Doppler ultrasound images of the patient were fused and matched on the sagittal section of the portal vein and the cross section of the right branch of portal vein, and stones and important vessels were marked on the images. After accurate positioning, a curette was used to remove the stones. Removal of biliary stones through hepatic parenchyma and peripheral dilated bile ducts was conducted at the site where stones obviously existed. After the stones were removed, the intrahepatic bile duct and hilar bile duct merged. The left end of the bile duct split was confirmed by real-time ultrasound. After location of portal vein was determined by ultrasound, vascular plastic surgery was perfomed to avoid stenosis. (3) Follow-up: 10 patients were followed up for 6-12 months, with a median follow-up time of 8 months. One of 10 patients was suspected residual stones at the right peripheral hepatic anterior lobe by postoperative angiography at 2 months after surgery, and was not removed stones by choledochoscope. The patient had no recurrent symptoms after T-tube removal. The other 9 patients had no residual stones. Conclusion RVS applied in complicated hepatolithiasis is helpful for the precise intraoperative diagnosis, and the surgical treatment can be safe and effective.
