ObjectiveTo investigate the effect and potential mechanism of caffeic acid （CA） on severe acute pancreatitis （SAP） induced by caerulein combined with lipopolysaccharide （LPS）， and to provide a basis for the research on novel drugs for the treatment of SAP. MethodsC57BL/6J mice， aged 6 weeks， were divided into control group， model group， CA group， and octreotide acetate （OA） group， with 6 mice in each group. The mice in the control group were given injection of normal saline， and those in the other groups were given intraperitoneal injection of caerulein combined with LPS to establish a mouse model of SAP. At 1 hour after the first injection of caerulein， the mice in the CA group and the OA group were given intraperitoneal injection of CA or subcutaneous injection of OA at an interval of 8 hours. The general status of the mice was observed after 24 hours of modeling， and serum， pancreas， lung， and colon samples were collected. HE staining was used to observe the histopathological changes of the pancreas and lungs， and the serum levels of α-amylase， lipase， tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6）， alanine aminotransferase， aspartate aminotransferase， and creatinine were measured. RT-PCR was used to measure the expression of proinflammatory factors in the pancreas and lungs； myeloperoxidase （MPO） immunohistochemistry was used to observe the degree of neutrophil infiltration； Western blot was used to measure the activation of nuclear factor-kappa B （NF-κB） and the level of citrullinated histone H3 （CitH3）， a marker for the formation of neutrophil extracellular traps （NETs）， in the pancreas and lungs， as well as the expression level of ZO-1 in colon tissue. A one-way analysis of variance was used for comparison of continuous data between multiple groups， and the Dunnett’s t-test was used for further comparison between two groups. ResultsCompared with the control group， the model group had severe injury in the pancreas and lungs and significant increases in the activity of serum α- amylase and lipase and the levels of the proinflammatory cytokines IL-6， interleukin-1β （IL-1β）， and TNF-α in serum and lung tissue （all P<0.05）， as well as significant increases in NF-κB activation， neutrophil infiltration， and the formation of NETs in the pancreas and lungs （all P<0.05）. Compared with the model group， the CA group had alleviated pathological injury of the pancreas and lungs and significant reductions in the activity of serum α-amylase and the levels of the proinflammatory cytokines IL-6， IL-1β， and TNF-α in serum and lung tissue （all P<0.05）， as well as significant reductions in NF-κB activation， neutrophil infiltration， and the formation of NETs in the pancreas and lungs （all P<0.05）. ConclusionCA can alleviate SAP induced by caerulein combined with LPS in mice， possibly by inhibiting neutrophil recruitment and the formation of NETs.

The paper reports acupuncture treatment for one case of oculomotor nerve palsy after cranial-orbital communicating tumor surgery. The acupoint prescription was composed of the local acupoints of the eyes (Yansanzhen, Tijian, Cuanzhu [BL2], Yuyao [EX-HN4] and Sizhukong [TE23]), the acupoints on the head, face and neck (Yangbai [GB14], Sibai [ST2] and Fengchi [GB20]), Guanyuan (CV4) on the abdomen, and those on the four limbs (Hegu [LI4], Zusanli [ST36], Shenmai [BL62] and Zhaohai [KI6]). The point-to-point needling technique with the eyelid lifted was operated at Tijian, Cuanzhu (BL2), Yuyao (EX-HN4), and Sizhukong (TE23). Warm needling with moxa cone placed on the needle handle was operated at Guanyuan (CV4) and Zusanli (ST36), and the usual needling technique was delivered at the rest acupoints. The treatment was given once daily, discontinued for 1 day after every 6 treatments. One course of treatment was composed of 7 days, and 6 courses were required. After treatment completion, the upper eyelids were basically symmetrical and the bilateral eye cracks were equal, the double vision appeared occasionally. No recurrence and no aggravation were reported in 1 month of follow up visit.

Heatstroke, a life-threatening illness, poses a significant risk to human health, particularly in high-temperature and high-humidity environments. Timely and effective on-site management is critical for improving patient survival and prognosis. Rapid recognition, rapid assessment, and rapid cooling are the cornerstones of pre-hospital care. However, the absence of a standardized protocol for pre-hospital management of heatstroke has impeded the efficacy of treatment. This consensus, initiated by the Expert Group on Heatstroke Prevention of the People's Liberation Army, signifies a collaborative endeavor involving emergency medical personnel, nurses, and administrators from pre-hospital care, emergency departments, and intensive care units in both military and civilian domains. By systematically reviewing evidence-based medicine and clinical expertise in heatstroke prevention, on-site and in-transit care, as well as early treatment in emergency settings, the group has formulated the Expert consensus on pre-hospital emergency management of heatstroke (2024) after extensive discussions and iterative recommendations, which serve as a scientific and standardized framework for pre-hospital heatstroke emergency care. The consensus underscores the pivotal role of enhancing public awareness regarding heatstroke prevention and augmenting the rates of rapid recognition and rapid cooling for effective on-site heatstroke management. In high-risk industries, regions, or seasons for heatstroke, developing scientifically sound plans and conducting practical training can provide effective safety measures. Emergency personnel should undergo specialized training and assessments in knowledge and skills, ambulances should be equipped with effective cooling devices, and hospitals must maintain comprehensive emergency response capabilities. It is recommended to establish a regional heatstroke treatment network to optimize the allocation of emergency resources and streamline processes, thereby improving treatment outcomes and response times.

Objective:To learn about physicians’ concepts and commonly employed method in hyaluronic acid injection and provide reference data for the standardization of pain management.Methods:This study was a cross-sectional study. Convenient sampling method was used to distribute questionnaires to cosmetic injectors and patients experienced with hyaluronic acid injections to collect data on their views of pain associated with hyaluronic acid injections. The physician portion was collected offline from June 15 to July 20, 2022, and the patient portion was collected from November 14, 2022, to December 6, 2022, via the Questionnaire Star platform. The physician questionnaire consisted of 17 questions, question types included single choice, multiple choice and essay questions. The patient questionnaire consisted of 6 questions, question types included single choice and multiple choice. Relevant data were analyzed using SPSS 22.0 software for descriptive statistics, and data were presented in the form of cases and percentages (%).Results:Sixty-two physician questionnaires and 123 patient questionnaires were collected. 42 (67.74%) physicians observed from their daily practice that more than 50% of their patients were very concerned about pain during injection; 101 (82.11%) patients scored ≥5 out of 10 for concern about impending pain prior to hyaluronic acid filler injection. At the time of treatment, 48 (77.42%) physicians advised patients to choose a lidocaine-containing hyaluronic acid filler for reasons including a significant reduction in injection pain (53 cases, 85.48%) and patient comfort with the treatment experience (59 cases, 95.16%). 60 (48.78%) patients were willing to choose an anesthesia-containing product at the time of injection, but the price of the anesthesia-containing product influenced the patient’ s choice (55 cases 44.72%) .Conclusions:Pain from cosmetic injectable treatments is an important issue to both physicians and patients. Lidocaine-containing hyaluronic acid is recognized by physicians and patients for its analgesic effect and high safety profile. There is no perfect solution for pain in cosmetic injection treatment, and multidisciplinary collaboration may be needed to solve the problem.

Objective:To compare the efficacy of pecto-intercostal fascial plane (PIFP) block versus transversus thoracic muscle plane (TTP) block under ultrasound guidance in coronary artery bypass grafting with general anesthesia.Methods:Ninety American Society of Anesthesiologists Physical Status classification Ⅱor Ⅲ patients of either sex, aged 50-79 yr, scheduled for elective coronary artery bypass grafting, were divided into 3 groups ( n=30 each) using a random number table method: PIFP block combined with general anesthesia group (PG group), TTP block combined with general anesthesia group (TG group), and general anesthesia group (G group). After anesthesia induction, bilateral PIFP block was performed under ultrasound guidance in group PG, TTP block was performed under ultrasound guidance in group TG. Three groups used the same general anesthesia method and patient-controlled intravenous analgesia after surgery. Visual analog scale scores (cough, position change, etc) at rest and during activity were recorded at 6, 12, 18 and 24 h after operation. The total consumption of intraoperative sufentanil, extubation time, length of stay in intensive care units, rate of rescue analgesia, effective pressing times of patient-controlled analgesia, incidence of postoperative nausea and vomiting, skin pruritus and nerve block-related adverse events were recorded. The operation time of nerve block was recorded and ultrasound-guided needle visibility score was assessed in PG group and TG group. Results:Compared with group G, the total consumption of intraoperative sufentanil was significantly reduced, the extubation time and length of stay in intensive care units were shortened, visual analog scale scores at rest and during activity were decreased at 6, 12 and 18 h after operation, the rate of rescue analgesia was decreased, and the effective pressing times of patient-controlled analgesia were decreased in group PG and group TG ( P<0.05), and no significant change was found in the aforementioned parameters in PG and TG groups ( P> 0.05). Compared with group TG, the operational time of nerve block was significantly shortened, and the ultrasound-guided needle visibility score was increased in group PG ( P<0.05). No nerve block-related adverse events were found in PG and TG groups. There was no significant difference in the incidence of postoperative nausea and vomiting and skin pruritus among the three groups ( P>0.05). Conclusions:PIFP block can provide good perioperative analgesia and promote the rapid recovery in the patients undergoing coronary artery bypass grafting with general anesthesia. Although the analgesic effect of PIFP blockade is similar to that of TTP blockade, PIFP blockade is more clinically valuable due to its simpler operation and less relative risk.

Objective:To investigate the clinical characteristics and management status of children with Turner syndrome (TS) in China.Methods:As a cross-sectional study, 1 089 TS patients were included in the database of the National Collaborative Alliance for the Diagnosis and Treatment of Turner Syndrome from August 2019 to November 2023. Clinical characteristics (growth development, sexual development, organ anomalies, etc.), karyotypes, auxiliary examinations, and treatments were collected and analyzed.Results:Among the 1 089 TS cases, 809 were recorded karyotypes. The karyotype distribution was as follows: 45, X in 317 cases (39.2%), X chromosome structural variants (including partial deletions of p or q arm, ring chromosome, and marker chromosome) in 89 cases (11.0%), 45, X/46, XX mosaicism in 158 cases (19.5%), mosaicism with X chromosome structural variants in 209 cases (25.8%), and presence of Y chromosome material in 36 cases (4.4%). Among the 824 TS cases, the age of diagnosis was 9.7(6.4, 12.2) years, with a height standard deviation score (HtSDS) of -3.1±1.2. Five hundred and fifty three cases underwent growth hormone (GH) stimulation test, and 352 cases (63.7%) had GH peak values <10 μg/L and 75.9% (577/760) had low IGF1 levels, with IGF1 SDS ≤-2 accounting for 38.2% (290 cases). Among 471 cases aged ≥8 years, 132 cases (28.0%) showed spontaneous sexual development (mean bone age (11.0±1.7) years), 10 cases had spontaneous menarche (mean bone age (12.0±2.2) years), and 2 cases had regular menstrual cycles. Common physical features included cubitus valgus (311 cases (28.5%)), neck webbing (188 cases (17.2%)), low posterior hairline (185 cases (17.0%)), shield chest (153 cases (14.0%)), high arched palate (127 cases (11.6%)), short fourth metacarpal (43 cases (3.9%)), and spinal abnormalities (38 cases (3.5%)). Congenital cardiovascular and urogenital anomalies occurred in 91 cases (19.4%) and 66 cases (12.0%)respectively. Abdominal ultrasound in 33 cases (7.2%) indicated fatty liver, hepatomegaly, intrahepatic bile duct stones, and splenomegaly. Among 23 cases undergoing oral glucose tolerance test (OGTT) test, 2 were diagnosed with diabetes mellitus and 4 with impaired glucose tolerance. Following diagnosis, 669 cases (80.7%) received rhGH treatment at a chronological age of (9±4) years and bone age of (8.3±3.2) years. Additionally, 112 cases (19.4%) received sex hormone replacement therapy starting at the age of (14±4) years and bone age of (12.6±1.2) years.Conclusions:The karyotypes of 45, X and mosaicism were most common in Chinese children with TS. The clinical manifestations were mainly short stature and gonadal dysplasia. However, a few TS children could be in the normal range of height, and some cases among those aged of ≥8 years old had spontaneous sexual development. Some exhibited physical features, congenital cardiovascular and urogenital anomalies, and dysfunction of the hypothalamic-pituitary-IGF1 axis. Moreover, a few of them developed impaired glucose tolerance and diabetes mellitus. Following diagnosis, most of the patients received rhGH treatment, and a few of them received sex hormone replacement therapy.

Objective To assess the impact of intravenous esketamine administered prior to car-diopulmonary bypass(CPB)initiation on ventricular function and internal carotid artery blood flow in pa-tients undergoing heart valve replacement surgery.Methods Sixty patients underwent elective CPB heart valve replacement,38 males and 22 females,aged 18-75 years,BMI 18.5-30.0 kg/m2,ASA physical status Ⅱ or Ⅲ,NYHA cardiac function classification Ⅰ-Ⅲ,and a left ventricular ejection fraction(LVEF)of≥45％,were selected.The patients were randomly divided into two groups:esketamine group(group E)and normal saline group(group C),30 patients in each group.Total intravenous anesthesia was used during the operation.Following the initiation of CPB,group E received an intravenous infusion of es-ketamine at a rate of 0.5 mg·kg-1·h-1 until the conclusion of the procedure,while group C received an equivalent volume of normal saline concurrently at the same rate.HR,MAP,CVP,and cardiac output index(CI)were recorded before anesthesia induction,during skin resection,and within 60 minutes after stopping CPB.LVEF,left ventricular global longitudinal strain(GLS),global longitudinal time-to-peak strain standard deviation(GLTSD),global circumferential strain(GCS),global circumferential time-to-peak strain standard deviation(GCTSD),right ventricular ejection fraction(RVEF),right ventricular GLS,and GLTSD were obtained during skin resection,within 40 minutes of CPB,and 60 minutes after stopping CPB.rScO2,BIS,concentrations of Hb and lactic acid(Lac),peak systolic flow velocity(SPV),quantity of flow-internal carotid artery(Q-ICA),and blood flow resistance index(RI)were recorded before anesthesia induction,during skin resection,within 40 minutes of CPB,and within 60 minutes after stopping CPB.Concentrations of cardiac troponin Ⅰ(cTnⅠ),alanine aminotransferase(ALT),creatinine(Cr),and neuron-specific enolase(NSE)were recorded before anesthesia induction and 6 hours after operation.Spon-taneous resuscitation after CPB,postoperative extubation time,duration of ICU stay,total hospital stay,in-cidence of adverse cardiac events,and 30-day postoperative mortality were recorded.Results Compared with group C,group E exhibited a significant increase in CI within 60 minutes after stopping CPB(P＜0.05).The LVEF,RVEF,and right ventricular GLS demonstrated significant increases within 60 minutes after stopping CPB in group E compared with group C(P＜0.05).The left ventricular GLS and left ven-tricular GCTSD displayed significant increases 30 minutes after stopping CPB in group E compared with group C.The RI exhibited a significant increase within 40 minutes of CPB in group E compared with group C(P＜0.05).There were no significant differences in cTnⅠ,ALT,Cr,NSE,spontaneous resuscitation affter CPB,postoperative extubation time,duration of ICU stay,total hospital stay,incidence of cardiac adverse events,and 30-day postoperative mortality between the two groups.Conclusion Administration of esket-amine following the onset of CPB in patients undergoing cardiac surgery demonstrates a significant elevation in CI post-CPB cessation.Furthermore,it may augment ventricular longitudinal strain,thereby enhancing myocardial contraction,leading to increased postoperative ventricular ejection fraction,and sustaining hemo-dynamic stability.
