Allergen-specific Immunotherapy (AIT) is currently the only allopathic treatment capable of modifying the natural course of immunoglobulin E (IgE)-mediated allergic diseases. Currently, there is a lack of recognized clinical markers for evaluating and predicting the efficacy of AIT, and some biological markers may have some potential for application. This article will summarize the currently known indicators for evaluating and predicting the therapeutic effects of AIT, with the aim of providing assistance in evaluating and monitoring the efficacy of AIT.

The prevalence of allergic diseases is on the rise,posing a significant global health challenge.Allergen specific immunotherapy(AIT)is the only treatment capable of altering the natural course of allergic diseases,offering long-term efficacy and the potential to prevent disease progression.However,its widespread application is hindered by factors such as lengthy treatment duration,adverse reactions,and patient compliance issues.In recent years,biologics targeting type 2 inflammatory pathways have played a crucial role at various stages of different allergic diseases.Research indicates that for patients with moderate to severe allergic diseases,using biologics during or prior to AIT can significantly enhance the safety of AIT,reduce the time required to reach maintenance doses,and markedly improve symptom scores.This article elucidates the synergistic mechanisms and recent advancements in the combined application of biologics and AIT in the treatment of allergic diseases.The aim is to provide a reference for the standardized treatment of allergic diseases.

Objective:This study aimed to explore the utility of transcutaneous electrical acupoint stimulation (TEAS) combined with skin sympathetic response (SSR) in assessing the effectiveness of perigastric autonomic nerve preservation during radical gastrectomy.Methods:A retrospective cohort analysis was conducted involving 221 patients who underwent laparoscopic radical gastrectomy at the Department of Gastric Surgery, Taizhou People's Hospital, affiliated with Nanjing Medical University, between June 2022 and September 2024. The cohort comprised 109 patients who underwent laparoscopic radical total gastrectomy without autonomic nerve preservation (total gastrectomy without nerve preservation group). Additionally, 112 patients underwent laparoscopic radical distal gastrectomy, including 34 patients who received autonomic nerve preservation (nerve preservation group) and 78 patients who did not (without nerve preservation group). TEAS was administered at the Zusanli and Tianshu acupoints one day before and one day after surgery, during which SSR latency and voltage amplitudes in the upper and lower extremities were recorded and compared across groups. Differences in SSR latency and voltage amplitude between the nerve preservation and non-nerve preservation groups of the distal gastrectomy cohort were also analyzed. Further, TEAS was applied at the same acupoints for 15 minutes on the 1st, 2nd, and 3rd postoperative days, and changes in intestinal sounds and intestinal functional recovery time were monitored. Surgical parameters, including operative duration, intraoperative blood loss, and harvested lymph node, were documented. Postoperative inflammatory indicators, including interleukin-6 (IL-6), C-reactive protein (CRP), procalcitonin (PCT), and the incidence of anastomotic leakage, were evaluated. At three months postoperatively, gastroscopy was performed to assess residual gastric food and bile reflux. Additionally, the prognostic nutritional index (PNI) was evaluated across all patient groups.Results:Following total gastrectomy, TEAS of Zusanli combined with arms' SSR revealed a latency of (23 59.71±410.55) ms and a voltage amplitude of (0.43±1.67) mV; for the legs, latency was (2 596.88±369.01) ms and voltage amplitude was (0.25±0.08) mV. TEAS of Tianshu combined with arms' SSR demonstrated a latency of (2 746.47±224.37) ms and a voltage amplitude of (0.31±0.14) mV; for the legs, latency was (2 891.90±193.61) ms and voltage amplitude was (0.19±0.72) mV. Postoperative latency was significantly prolonged, and voltage amplitude was markedly reduced (all P < 0.01). In the distal gastrectomy with nerve preservation group, TEAS of Zusanli combined with arms' SSR showed a latency of (1 668.04±261.91) ms and a voltage amplitude of (0.78±0.26) mV; for the legs, latency was (1 568.86±220.09) ms and voltage amplitude was (0.61±0.24) mV. TEAS of Tianshu combined with arms' SSR demonstrated a latency of (1 519.36±206.99) ms and a voltage amplitude of (0.66±0.34) mV; for the legs, latency was (2 004.80±508.53) ms and voltage amplitude was (0.55±0.28) mV. In the distal gastrectomy without nerve preservation group, TEAS of Zusanli combined with arms' SSR revealed a latency of (2 385.95±710.27) ms and a voltage amplitude of (0.23±0.11) mV; for the legs, latency was (2 506.81±779.37) ms and voltage amplitude was (0.26±1.29) mV. TEAS of Tianshu combined with arms' SSR indicated a latency of (2 697.78±385.55) ms and a voltage amplitude of (0.21±0.14) mV; for the legs, latency was (2 949.14±506.61) ms and voltage amplitude was (0.17±0.11) mV. The group without nerve preservation exhibited significantly prolonged latencies and reduced voltage amplitudes (all P<0.01). No statistically significant differences were observed between the groups in operative time, intraoperative bleeding, the number of dissected lymph nodes, inflammatory indicators (IL-6, CRP, PCT) at 3 days postoperatively, or anastomotic leakage rates (all P>0.05). In the group without nerve preservation, bowel sounds on postoperative days 1, 2, and 3 were (0.36±0.58), (1.04±0.97), and (1.74±1.10) times/min, respectively, with bowel function recovery time of (62.24±9.91) hours. The PNI at 3 months postoperatively was (37.42±3.01). Incidences of food residue in the residual stomach and bile reflux were 21.79% (17/78) and 29.49% (23/78), respectively. In the group with nerve preservation, bowel sounds on postoperative days 1, 2, and 3 were (0.76±0.82), (2.03±1.34), and (3.71±1.27) times/min, respectively, with bowel function recovery time of (44.94±8.05) hours. The PNI at 3 months postoperatively was (41.34±3.40). Incidences of food residue and bile reflux were 5.88% (2/34) and 11.76% (4/34), respectively. Statistically significant differences were observed between the groups (all P < 0.05). Conclusion:TEAS of Zusanli and Tianshu combined with SSR provides an objective measure for assessing the preservation of perigastric autonomic nerves during radical gastrectomy.

Objective:To investigate the impact of peak pressure upon different bone densities during autonomous puncture by orthopedic robot on puncture path deviation and bone cement leakage.Methods:A spinal surgery robot system was designed for autonomous vertebral puncture and bone cement injection, and six porcine spine specimens were used for single-segment or double-segment simulated percutaneous vertebral augmentation surgery. The accuracy of puncture path (Gertzbein-Robbins grading), bone cement leakage classification, and peak bone drill pressure were measured to assess the accuracy of autonomous vertebral puncture and bone cement leakage in vertebral cortical and cancellous bone of different densities.Results:A total of 64 porcine vertebrae were simulated for puncture, among which 53 vertebrae were classified as Grade A, 8 as Grade B, and 3 as Grade C according to the Gertzbein-Robbins grading. The cortical bone pressure of Grade A vertebrae was 6.663±0.319 N which was lower than that of Grade B (8.348±0.418 N) and Grade C (11.500±0.600 N), with significant differences ( F=341.000, P<0.001). The cancellous bone pressure of Grade A, B, and C vertebrae were 3.660±0.317, 3.594±0.608, and 4.117±0.257 N, respectively, with no significant difference ( F=2.496, P=0.091). There were 40 cases of no leakage, 20 cases of Type I leakage (leakage into the surrounding vertebrae), and 3 cases of Type II leakage (leakage into the vertebral canal), with an overall leakage rate of 36% (23/64). The peak cortical bone pressure for no leakage, Type I, and Type II leakage was 6.638±0.301, 6.792±0.404, and 6.753±0.473 N, respectively, and the peak cancellous bone pressure was 3.634±0.279, 3.783±0.423, and 3.920±0.255 N, respectively, with no significant difference ( F=1.521, P=0.227; F=2.106, P=0.131). Conclusion:During the autonomous puncture process of the novel orthopedic robot, the accuracy of autonomous puncture path decreased when the puncture pressure through the cortical bone was high, and the probability of invading the pedicle increased. The puncture pressure of cortical and cancellous bone had no significant effect on the occurrence rate of bone cement leakage.

Objective:To analyze the distribution and drug resistance of pathogens of bacterial bloodstream infection in patients with hematological diseases in the Department of Hematology of Tianjin Medical University General Hospital, and to provide etiological data for clinical empirical anti-infection treatment.Methods:A retrospective analysis was conducted on the general clinical information, pathogenic bacteria and drug susceptibility test results of patients with hematological diseases diagnosed with bacterial bloodstream infection by menstrual blood culture in our center from January 2016 to December 2022.Results:Patients included 498 inpatients, with a total of 639 bacterial strains. Among the patients, 86.9% patients had malignancies, and 76.7% had agranulocytosis. Symptoms of concurrent infections, including those of the respiratory tract, oral mucosa, skin and soft tissues, and abdominal sources were observed in 68.3% patients. Gram-negative bacteria (G -) accounted for 79.0% of the isolated bacteria, and gram-positive bacteria (G +) accounted for 21.0%. The top five isolated pathogens were Klebsiella pneumoniae (22.5%), Escherichia coli (20.8%), Pseudomonas aeruginosa (15.0%), Enterococcus faecium (5.5%), and Stenotrophomonas maltophilum (5.0%). Escherichia coli exhibited a decreasing trend of resistance to quinolones, cephalosporins, and carbapenems. Klebsiella pneumoniae exhibited increasing rates of resistance to quinolones and cephalosporins between 2016 and 2018, but the rated decreased after 2019. The resistance rate to carbapenems exhibited by Pseudomonas aeruginosa was approximately 20%. Carbapenem-resistant strains of Pseudomonas aeruginosa strains were first detected in 2017, with a peak resistance rate of 35.7%, detected in 2019. A 60.0% resistance rate to methicillin was observed in methicillin-resistant coagulase-negative staphylococci (MRCNS), and one case of linezolid-resistant MRCNS was detected. Conclusions:Pathogenic bacteria of bacterial bloodstream infections were widely distributed in our center, and precautions are warranted against carbapenem resistant P. aeruginosa and Klebsiella pneumoniae.

Objective:To investigate the expulsion rate of GyneFix postpartum intrauterine device (PPIUD) placed immediately after cesarean section within one year and its influencing factors.Methods:A prospective cohort study was conducted. Women who volunteered to use a GyneFix PPIUD placed immediately after cesarean section (within 10 min after placenta delivery) for postpartum contraception were recruited from September 2017 to November 2020. The relevant information was collected through questionnaires before, during and 24 h after cesarean section. Outpatient follow-up was conducted at 42 d, 3 months, 6 months and 12 months after delivery to obtain information on expulsion of GyneFix PPIUD and unwanted pregnancy. Life table and Cox regression model were used to analyze the cumulative expulsion rate and related influencing factors.Results:A total of 470 subjects were recruited and 461 (98%) subjects were eligible for this study. The cumulative expulsion rate of GyneFix PPIUD within one year after cesarean section was 8.4% (95% CI: 7.0%-9.8%). Multivariate Cox regression analysis showed that women aged >35 years had significantly lower risk of PPIUD expulsion than those aged <25 years ( HR=0.16, 95% CI: 0.04-0.64). The risk of GyneFix PPIUD was not statistically significantly associated with cesarean section history and breastfeeding mode (all P>0.05). Nevertheless, this risk was statistically significant between hospitals. The Pearl index of contraceptive failure of the device was 2.37 (95% CI: 1.09-4.50) per 100 person-years. The rate of contraceptive failure was not associated with maternal age, breastfeeding mode, and history of cesarean delivery (all P>0.05). Conclusion:The one-year cumulative expulsion rate of GyneFix PPIUD placed immediately after cesarean section is 8.4%. Young mothers were at a higher risk of expulsion than their older counterparts. The device users should be counseled regarding the signs of expulsion. In case of expulsion, women should be offered reinsertion or other contraceptive methods. The training of service skills of GyneFix PPIUD should be strengthened in order to mitigate the risk of the device expulsion.
