Objective:To evaluate the effect of preemptive analgesia with ibuprofen on postoperative pain following single posterior tooth implantation, aiming to provide a clinical reference for its application.Methods:A multicenter, randomized, double-blind, placebo-controlled parallel-group trial was conducted. A total of 82 participants were included in the trial, meeting the eligibility criteria from April 2022 to April 2024 at the Capital Medical University School of Stomatology (40 cases), Beijing TianTan Hospital, Capital Medical University (22 cases), Beijing Chao-Yang Hospital, Capital Medical University (20 cases). Participants were randomly assigned in a 1∶1 ratio to either the ibuprofen group or the control group, with each group comprising 41 individuals. Participants in the ibuprofen group received 300 mg of sustained-release ibuprofen capsules orally 15 min before surgery, while the control group received a placebo. Both groups received the same postoperative analgesic regimen for 3 days. Pain scores were assessed using the numerical rating scale at 30 min, 4 h, 6 h, 8 h, 24 h, 48 h, and 72 h postoperatively, and the additional use of analgesic medication was recorded from days 4 to 6 postoperatively.Results:A total of 82 participants were initially enrolled in the study, with 7 dropouts (4 from the control group and 3 from the ibuprofen group), resulting in 75 participants (37 in the control group and 38 in the ibuprofen group) completing the trial. There were no reports of adverse events such as nausea or vomiting among the participants. The ibuprofen group exhibited significantly lower pain scores at 4 h, 6 h and 8 h [1.0 (0.0, 2.0), 1.0 (0.0, 2.0), 1.5 (0.0, 3.0) ] postoperatively compared to the control group 4 h, 6 h and 8 h [2.0 (1.0, 3.0), 3.0 (1.5, 4.0), 2.0 (1.0, 4.0)] ( Z=-1.99, P=0.047; Z=-3.01, P=0.003; Z=-2.10, P=0.036). The proportions of patients requiring additional analgesic medication between days 4 and 6 post-surgery were 18.4% (7/38) in the ibuprofen group and 27.0% (10/37) in the control group, with no significant difference (χ 2=0.79, P=0.373). The median additional medication usage postoperatively was [0.0 (0.0, 0.0) pills] in the ibuprofen group and [0.0 (0.0, 1.0) pills] in the control group, with no significant difference ( Z=-0.78, P=0.439). Conclusions:Preemptive analgesia with ibuprofen effectively reduces postoperative pain following tooth implantation, representing a safe and effective perioperative pain management strategy.

Objective To investigate the clinical characteristics and prognosis of pneumococcal meningitis(PM),and drug sensitivity of Streptococcus pneumoniae(SP)isolates in Chinese children.Methods A retrospective analysis was conducted on clinical information,laboratory data,and microbiological data of 160 hospitalized children under 15 years old with PM from January 2019 to December 2020 in 33 tertiary hospitals across the country.Results Among the 160 children with PM,there were 103 males and 57 females.The age ranged from 15 days to 15 years,with 109 cases(68.1% )aged 3 months to under 3 years.SP strains were isolated from 95 cases(59.4% )in cerebrospinal fluid cultures and from 57 cases(35.6% )in blood cultures.The positive rates of SP detection by cerebrospinal fluid metagenomic next-generation sequencing and cerebrospinal fluid SP antigen testing were 40% (35/87)and 27% (21/78),respectively.Fifty-five cases(34.4% )had one or more risk factors for purulent meningitis,113 cases(70.6% )had one or more extra-cranial infectious foci,and 18 cases(11.3% )had underlying diseases.The most common clinical symptoms were fever(147 cases,91.9% ),followed by lethargy(98 cases,61.3% )and vomiting(61 cases,38.1% ).Sixty-nine cases(43.1% )experienced intracranial complications during hospitalization,with subdural effusion and/or empyema being the most common complication[43 cases(26.9% )],followed by hydrocephalus in 24 cases(15.0% ),brain abscess in 23 cases(14.4% ),and cerebral hemorrhage in 8 cases(5.0% ).Subdural effusion and/or empyema and hydrocephalus mainly occurred in children under 1 year old,with rates of 91% (39/43)and 83% (20/24),respectively.SP strains exhibited complete sensitivity to vancomycin(100% ,75/75),linezolid(100% ,56/56),and meropenem(100% ,6/6).High sensitivity rates were also observed for levofloxacin(81% ,22/27),moxifloxacin(82% ,14/17),rifampicin(96% ,25/26),and chloramphenicol(91% ,21/23).However,low sensitivity rates were found for penicillin(16% ,11/68)and clindamycin(6% ,1/17),and SP strains were completely resistant to erythromycin(100% ,31/31).The rates of discharge with cure and improvement were 22.5% (36/160)and 66.2% (106/160),respectively,while 18 cases(11.3% )had adverse outcomes.Conclusions Pediatric PM is more common in children aged 3 months to under 3 years.Intracranial complications are more frequently observed in children under 1 year old.Fever is the most common clinical manifestation of PM,and subdural effusion/emphysema and hydrocephalus are the most frequent complications.Non-culture detection methods for cerebrospinal fluid can improve pathogen detection rates.Adverse outcomes can be noted in more than 10% of PM cases.SP strains are high sensitivity to vancomycin,linezolid,meropenem,levofloxacin,moxifloxacin,rifampicin,and chloramphenicol.[Chinese Journal of Contemporary Pediatrics,2024,26(2):131-138]

The gastroduodenal artery (GDA) has an important role in pancreatic surgery. Relevant literature was reviewed and sum-marized in this article, along with practical experiences from our center, in order to provide references for surgeons in dealing with anatomical variations of the GDA and postoperative bleeding. GDA has close relationships with the blood supply of surroun-ding organs and is the most common vessel associated with intra-abdominal bleeding after pancreatic surgery. Therefore, the GDA plays a crucial anatomical role that affects the strategies and approaches of pancreatic surgery . Preoperative assessment of GDA variations can be achieved through CT angio-graphy. During surgery, it is important to identify and dissect the GDA properly and protect its remnants. In cases of residual bleeding from the GDA, endovascular treatment or secondary laparo-tomy can be conducted.

OBJECTIVE: To explore the risk factors of cytomegalovirus (CMV) and refractory CMV infection (RCI) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) and their influences on survival. METHODS: A total of 246 patients who received allo-HSCT from 2015 to 2020 were divided into CMV group (n=67) and non-CMV group (n=179) according to whether they had CMV infection. Patients with CMV infection were further divided into RCI group (n=18) and non-RCI group (n=49) according to whether they had RCI. The risk factors of CMV infection and RCI were analyzed, and the diagnostic significance of Logistics regression model was verified by ROC curve. The differences of overall survival (OS) and progression-free survival (PFS) between groups and the risk factors affecting OS were analyzed. RESULTS: For patients with CMV infection, the median time of the first CMV infection was 48(7-183) days after allo-HSCT, and the median duration was 21 (7-158) days. Older age, EB viremia and gradeⅡ-Ⅳacute graft-versus-host disease (aGVHD) significantly increased the risk of CMV infection (P=0.032, <0.001 and 0.037, respectively). Risk factors for RCI were EB viremia and the peak value of CMV-DNA at diagnosis≥1×10⁴ copies/ml (P=0.039 and 0.006, respectively). White blood cell (WBC)≥4×10⁹/L at 14 days after transplantation was a protective factor for CMV infection and RCI (P=0.013 and 0.014, respectively). The OS rate in CMV group was significantly lower than that in non-CMV group (P=0.033), and also significantly lower in RCI group than that in non-RCI group (P=0.043). Hematopoietic reconstruction was a favorable factor for OS (P<0.001), whereas CMV-DNA≥1.0×10⁴ copies/ml within 60 days after transplantation was a risk factor for OS (P=0.005). CONCLUSION The late recovery of WBC and the combination of EB viremia after transplantation are common risk factors for CMV infection and RCI. CMV-DNA load of 1×10⁴ copies/ml is an important threshold, higher than which is associated with higher RCI and lower OS risk.

A boy, aged 16 months, attended the hospital due to head and facial erythema for 15 months and vulva erythema for 10 months with aggravation for 5 days. The boy developed perioral and periocular erythema in the neonatal period and had erythema and papules with desquamation and erosion in the neck, armpit, and trigone of vulva in infancy. Blood gas analysis showed metabolic acidosis; the analysis of amino acid and acylcarnitine profiles for inherited metabolic diseases and the analysis of organic acid in urine suggested multiple carboxylase deficiency; genetic testing showed a homozygous mutation of c.1522C>T(p.R508W) in the HLCS gene. Finally the boy was diagnosed with holocarboxylase synthetase deficiency and achieved a good clinical outcome after oral biotin treatment. This article analyzes the clinical data of a child with holocarboxylase synthetase deficiency and summarizes the etiology, diagnosis, and treatment of this child, so as to provide ideas for clinicians to diagnose this rare disease.

Objective: To evaluate and compare the short-term efficacy of domestic mechanical-locked (Clip2Edge) and elastic self-locked (ValveClip) transcranial mitral valve edge-to-edge interventional repair (TEER) devices in the treatment of functional mitral regurgitant valves. Methods: In this retrospective non-randomized comparative study, patients underwent TEER procedure in Fuwai Yunnan Cardiovascular Disease Hospital from May 2022 to April 2023 for heart failure combined with moderate to severe or severe functional mitral valve were divided into Clip2Edge and ValveClip groups based on the TEER system used. Baseline, perioperative, and postoperative 30 d follow-up data were collected and compared between the two groups. The primary outcome was the success rate on the 30 d post operation, while secondary outcomes included immediate postoperative technical success rate and the incidence of all-cause mortality on the 30 d post operation, readmission rate of acute heart failure, cerebral infarction, severe bleeding, and other serious adverse events rates. Results: A total of 60 patients were enrolled, 34 patients were in the Clip2Edge group and 26 in the ValveClip group, mean age was (63.8±9.3) years, and 24 patients (40%) were female. There were no significant differences in baseline data of age, cardiac function, comorbidities, mitral regurgitation 4+(19(73%) vs. 29(85%)), the end-diastolic volume of left ventricle ((220.8±91.2) ml vs. (210.8±71.7) ml) between the two groups (all P>0.05). The technical success rate immediately after the procedure was 100%. There were no readmission of acute heart failure, death, cerebral infarction, severe bleeding, and other serious adverse events up to the 30 d follow-up. Device success rate was similar between the ValveClip group (24 cases (100%)) and the Clip2Edge group (27 cases (96%)) (P>0.05). Conclusion: Both types of novel domestic TEER devices are safe and feasible in treating patients with functional mitral regurgitation.

Lower extremity deep vein thrombosis (DVT) is one of the main complications in patients with traumatic fractures, and for severe patients, the DVT can even affect arterial blood supply, resulting in insufficient limb blood supply. If the thrombus breaks off, pulmonary embolism may occur, with a high mortality. The treatment and rehabilitation strategies of thrombosis in patients with lower extremity fractures have its particularity. DVT in traumatic fractures patients has attracted extensive attention and been largely studied, and the measures for prevention and treatment of DVT are constantly developing. In recent years, a series of thrombosis prevention and treatment guidelines have been updated at home and abroad, but there are still many doubts about the prevention and treatment of DVT in patients with different traumatic fractures. Accordingly, on the basis of summarizing the latest evidence-based medical evidence at home and abroad and the clinical experience of the majority of experts, the authors summarize the clinical treatment and prevention protocols for DVT in patients with traumatic fractures, and make this consensus on the examination and assessment, treatment, prevention and preventive measures for DVT in patients with different fractures so as to provide a practicable approach suitable for China ′s national conditions and improve the prognosis and the life quality of patients.

Objective:To study the safety and treatment outcomes of portal vein embolization (PVE) combined with lenvatinib plus an anti-programmed death-1(PD-1) antibody to treat patients with initially unreasectable hepatocellular carcinoma (uHCC).Methods:This study retrospectively analyzed the data of six patients with uHCC who received first-line combined systemic therapy with lenvatinib plus an anti-PD-1 antibody, and then underwent pre-hepatectomy PVE at the Department of Liver Surgery at Zhongshan Hospital, Fudan University from May 2019 to November 2020. All enrolled patients were males, aged (54.6±6.2) (ranged 46 to 63) years. Tumor response and liver volume were evaluated by medical imagings once every 2 months (±2 weeks) and evaluated using the Response Evaluation Criteria in Solid Tumours (version 1.1). Patients were followed-up by outpatient interviews or by phone calls to record their survival and tumor outcome status.Results:Three of the six enrolled patients had Barcelona Clinic Liver Cancer stage A and three had stage B disease. One patient achieved a partial response and five patients had stable diseases. The mean ± s. d. future liver remnant (FLR) percentage was (29.0±8.9) % before PVE and the combination therapy, and was (41.3±10.8) % before the last evaluation for liver surgery ( t=10.79, P<0.001). Hepatectomy was carried out in five patients, and one patient who failed to develop significant FLR hypertrophy did not undergo hepatectomy. Grade B post-hepatectomy liver failure and major postoperative complications (i.e. pleural effusion requiring additional percutaneous drainage) occurred in one patient. After a median post-operative follow-up of 4.5 (range: 1.0-12.3) months, all five patients were alive and were tumor free. Conclusion:PVE followed by hepatectomy is feasible in a uHCC patients receiving systemic therapy with lenvatinib and an anti-PD-1 antibody.
