AIM: To explore the clinical application effect of visual training equipment combined with conventional corrective treatment on children with ametropic amblyopia(AMA).METHODS: Prospective randomized control study. A total of 188 children(376 eyes)with AMA treated in our hospital from June 2021 to December 2022 were selected, and they were divided into two groups using a random number table. The conventional correction group(94 cases, 188 eyes)received conventional correction treatment, while the visual training group(94 cases, 188 eyes)received visual training equipment combined with conventional correction treatment, both lasted for 12 mo. The best corrected visual acuity, diopter, eye accommodation function, adverse reactions, amblyopia recurrence rates, and clinical efficacy were compared between the two groups at 6 and 12 mo after treatment.RESULTS:The two groups each had 8 cases(16 eyes)detached, the rate of loss to follow-up was 8.5%, and 86 cases(172 eyes)were included in each group. There were statistically significant differences in the best corrected visual acuity, diopter, amplitude of accommodation, accommodation facility and accommodative lag between the two groups of children before and after treatment(all P<0.05). The total effective rate of the visual training group(98.8%)was higher than that of the conventional correction group(91.9%; P<0.05). There was no statistically significant difference in the total effective rate of clinical efficacy between the two groups in different age groups and different degrees of amblyopia(all P>0.05). There was no statistically significant difference in the incidence of redness and swelling between the two groups(P>0.05). The recurrence rate of amblyopia in the visual training group(1.2%)was lower than that in the conventional correction group(8.1%; P<0.05).CONCLUSION: The combination of visual training equipment and conventional correction therapy has a significant clinical effect on children with AMA, which can effectively correct visual acuity, adjusting diopter and improve eye accommodation function, and recurrence rate of amblyopia is low and safety is high.

OBJECTIVE: To investigate the feasibility and prognostic implications of assessing volume status during early fluid resuscitation in septic patients based on estimated plasma volume status (ePVS). METHODS: A prospective study was conducted. Patients with sepsis admitted to intensive care unit (ICU) of the First Affiliated Hospital of Kunming Medical University from March to December in 2023 were enrolled. The general information and laboratory indicators at ICU admission were recorded, and ePVS, sequential organ failure assessment (SOFA) score, acute physiology and chronic health status evaluation II (APACHE II) score were calculated. The vital signs, arterial blood gas analysis and volume status related indicators before liquid resuscitation (T0h) and 3 hours (T3h) and 6 hours (T6h) of fluid resuscitation were recorded. The diameter and variability of the inferior vena cava (IVC) were measured by ultrasound, and ePVS, percentage change value of estimated plasma volume status (ΔePVS%), difference in central venous-to-arterial partial pressure of carbon dioxide (Pcv-aCO₂), and lactate clearance rate (LCR) were calculated. Patients were divided into sepsis group and septic shock group based on the diagnosis at ICU admission, and septic patients were subdivided into survival group and death group based on their 28-day survival status. The differences in clinical data between the groups were compared. The correlation between ePVS or ΔePVS% and volume status related indicators during early liquid resuscitation was analyzed by Spearman rank sum correlation test. The predictive value of each variable for 28-day survival in patients with sepsis was analyzed by receiver operator characteristic curve (ROC curve), and 28-day death risk factors were analyzed by Logistic regression method. RESULTS: Fifty-four septic patients were enrolled in the final analysis, including 17 with sepsis and 37 with septic shock; 34 survived at 28 days and 20 died, with a 28-day survival rate of 63.0%. Compared with the sepsis group, the septic shock group had a lower venous ePVS at ICU admission [dL/g: 4.96 (3.67, 7.15) vs. 7.55 (4.36, 10.07), P < 0.05]. Compared with the death group, the survival group had higher T6h arterial and venous ΔePVS%, and albumin [Alb; T6h arterial ΔePVS% (%): 11.57% (-1.82%, 31.35%) vs. 0.48% (-5.67%, 6.02%), T6h venous ΔePVS%: 9.62% (3.59%, 25.75%) vs. 1.52% (-9.65%, 7.72%), Alb (g/L): 27.57±4.15 vs. 23.77±6.97, all P < 0.05], lower SOFA score, APACHE II score, AST, T0h Lac, and T3h and T6h norepinephrine dosage [SOFA score: 9.00 (8.00, 10.00) vs. 11.50 (9.25, 14.50), APACHE II score: 18.00 (14.75, 21.25) vs. 25.50 (21.00, 30.00), AST (U/L): 34.09 (23.20, 56.64) vs. 79.24 (25.34, 196.59), T0h Lac (mmol/L): 1.75 (1.40, 2.93) vs. 3.25 (2.33, 5.30), norepinephrine dosage (mg): 0.98 (< 0.01, 3.10) vs. 4.60 (1.05, 8.55) at T3h, 1.82 (0.38, 5.30) vs. 8.20 (2.80, 17.73) at T6h, all P < 0.05]. While there were no significantly differences in other basic data and ePVS at all of the time points before and after resuscitation between the two groups. Correlation analysis showed that T6h venous ePVS was significantly positively correlated with T6h IVC variability in septic patients (r = 0.360, P < 0.05), T0h arterial ePVS was significantly negatively correlated with T3h and T6h liquid intake volume (r₁ = -0.367, r₂ = -0.280, both P < 0.05), and venous ePVS at ICU admission was significantly positively correlated with NT-proBNP at ICU admission (r = 0.409, P < 0.05). T6h venous ΔePVS% was significantly positively correlated with T3h liquid intake volume and T6h LCR (r₁ = 0.286, r₂ = 0.286, both P < 0.05), and significantly negatively correlated with T6h urine volume and T6h change value of Pcv-aCO₂ (ΔPcv-aCO₂; r₁ = -0.321, r₂ = -0.371, both P < 0.05). ROC curve analysis showed that the area under the ROC curve (AUC) of T6h venous ΔePVS% for predicting 28-day survival in septic patients was 0.726 [95% confidence interval (95%CI) was 0.578-0.875, P = 0.006], with a sensitivity of 82.4%, a specificity of 60.0%, and an optimal cut-off value of 3.09%. Binary multifactorial Logistic regression analysis showed that an increase in T6h venous ΔePVS% was a protective factor for 28-day death in patients with sepsis on early fluid resuscitation [odds ratio (OR) = 0.900, 95%CI was 0.834-0.972, P = 0.007]. CONCLUSIONS ePVS may have potential for assessing the volume status of septic patients during early fluid resuscitation. The ΔePVS% during early fluid resuscitation may help to identify septic patients with a poor prognosis.

Objective:To investigate the effects of electroacupuncture on duodenal inflammation and intestinal mucosal barrier function in functional dyspepsia(FD)rats based on the Toll-like receptors 4(TLR4)/myeloid differentiation factor 88(Myd88)pathway.Methods:Sixty male Sprague-Dawley rats were randomly divided into a blank group(n=10)and a modeling group(n=50).The FD model was induced in the modeling group using a multi-factor comprehensive intervention.Forty successful model rats were randomly allocated into a model(FD)group,an electroacupuncture(EA)group,a TLR4 inhibitor(TAK242)group,and an EA+TAK242 group,with 10 rats in each group.In the EA group,following acupuncture at Zusanli(ST36)and Taichong(LR3),a filiform needle was perpendicularly inserted 3 mm into the lateral side of Zusanli(ST36)bilaterally,positioned between the Stomach Meridian and the Gallbladder Meridian at the lateral edge of the tibia,serving as an auxiliary electrode.An EA instrument was then connected to Zusanli(ST36)and the auxiliary electrode on the same side for intervention.The TAK242 group received tail vein injections of TLR4 inhibitor TAK242[0.5 mg/(kg·bw)],while the EA+TAK242 group received both TAK242 injections and EA intervention.Intragastric residual rate and small intestinal propulsion rate were observed in each group.Immunohistochemistry was used to detect tryptase expression in the duodenum;enzyme-linked immunosorbent assay was used to measure serum concentrations of 5-hydroxytryptamine(5-HT)and 5-hydroxyindole acetic acid(5-HIAA);Western blotting was used to analyze TLR4,MyD88,zonula occludens-1(ZO-1),and junctional adhesion molecule A(JAM-A)protein expression in the duodenal tissue.Results:In the FD group,the intragastric residual rate increased,small intestinal propulsion rate decreased,ZO-1 and JAM-A protein expression decreased,duodenal tryptase mean optical density increased,serum 5-HT and 5-HIAA levels increased significantly,and TLR4 and MyD88 protein expression increased significantly compared to the blank group(P<0.01).Compared to the FD group,the EA,TAK242,and EA+TAK242 groups showed a decreased gastric residual rate,increased small intestinal propulsion rate,increased ZO-1 and JAM-A protein expression,decreased optical density of duodenal tryptase,and significantly reduced serum 5-HT and 5-HIAA,as well as decreased TLR4 and MyD88 protein levels(P<0.01).Compared to the EA group,the TAK242 group had a higher intragastric residual rate and lower small intestinal propulsion rate(P<0.05),decreased TLR4 protein expression(P<0.05),no significant change in MyD88 protein expression(P>0.05),increased optical density of duodenal tryptase(P<0.05),increased serum 5-HT and 5-HIAA levels(P<0.05),and decreased ZO-1 and JAM-A protein expression(P<0.05).In the EA+TAK242 group,the intragastric residual rate was significantly lower,small intestinal propulsion rate was significantly higher,TLR4 and MyD88 protein expression was significantly lower,optical density of duodenal tryptase was significantly lower,and ZO-1 and JAM-A protein expression levels were significantly higher compared to the EA and TAK242 groups(P<0.01).Conclusion:EA promotes gastrointestinal motility,restores intestinal mucosal barrier function,and reduces inflammatory responses in FD rats,potentially through the down-regulation of the TLR4/Myd88 pathway.

Spine fracture and dislocation are common traumatic spinal conditions that often require surgical intervention due to compromised spinal stability. Surgical approaches include anterior, posterior, and combined anterior-posterior spinal procedures. According to the specific surgical requirements, patients may be placed in the prone position or repositioned between prone and supine positions during surgery. Intraoperative repositioning has become an essential step in patient positioning. However, during repositioning, patients with spinal fracture and dislocation are at increased risk for complications such as hemodynamic instability, nerve injury, and pressure injuries to the skin and soft tissue. Notably, due to the instability of the spinal cord, even minor manipulations can further exacerbate the damage, potentially leading to severe outcomes like paraplegia. Although the current clinical guidelines provide instructive recommendations for standard position, there remains no specific protocols for intraoperative repositioning in patients with spine fracture and dislocation. With a concern for the lack of clinical studies on positioning techniques, risk prevention, and operational norms for special patients, no applicable guidelines or standards are available. A consensus was required to provide clinical reference, meet the requirements of surgical treatment, and minimize the safety risks of patients caused by improper placement of positions. Professional Committee of Operating Room Nursing of Shaanxi Nursing Association organized experts in nursing management and operating room nursing from major hospitals across China to formulate Expert consensus on intraoperative repositioning for patients with spinal fracture and dislocation ( version 2025). The consensus provides 11 recommendations covering pre-repositioning preparation, intraoperative maneuvers, and post-repositioning observation, aiming to provide references for clinical standardization of the intraoperative repositioning process and protection of patients′ safety.

The paper reports a 32-year-old female acute myeloid leukemia patient who developed graft-versus-host disease after paternal hematopoietic stem cell transplantation, which subsequently led to renal thrombotic microangiopathy. She subsequently required a kidney transplant from the same donor 5 years later due to renal failure. Considering that both the bone marrow and kidney were from the same donor and the recovery of renal function was favorable, immunosuppressive therapy was discontinued after a short course of anti-rejection treatment, with maintained stable kidney function. This case suggests that under the condition of high chimerism, allogeneic hematopoietic stem cell transplantation and kidney transplantation from the same donor can achieve immune tolerance, potentially improving solid organ transplantation success rate. The findings provide a novel therapeutic approach for solid organ transplantation following allogeneic hematopoietic stem cell transplantation.

One patient with gallbladder mass had transient jaundice and was diagnosed with gallbladder carcinoma by abdominal ultrasonography， contrast-enhanced CT， MRCP， and PET-CT. Surgical exploration showed enlarged gallbladder and a mass in the neck of the gallbladder pressing against the hilum of the liver， with no manifestation of tumor invasion， and there were no signs of liver metastasis. Only cholecystectomy was performed for the patient. The pathological diagnosis was tubular adenoma of the gallbladder without carcinogenesis. This case is characterized by a large gallbladder tumor， without marginal infiltration on imaging or malignant transformation based on pathology.

Objective To evaluate the apparent diffusion coefficient(ADC)values of different bone marrow infiltration patterns in multiple myeloma(MM)patients with MR whole-body diffusion weighted imaging(WB-DWI)and to determine the ADC thresholds for different bone marrow infiltration patterns.Methods Nineteen MM patients diagnosed for the first time were selected.The lesions types of each site(cervical spine,ribs,sternum,humerus,scapula,sacral spine,ilium,femur,thoracic spine,and lumbar spine)after the WB-DWI images were visually evaluated,which were divided into focal group(including focal lesion in combined focal and diffuse infiltration)[region of interest(ROI)=141],pure diffuse infiltration group(ROI=150),diffuse lesion in combined focal and diffuse infiltration group(ROI=127),"salt-and-pepper"group(ROI=54),and normal appearance group(ROI=68).ADC values were measured and compared between each group and the receiver operating characteristic(ROC)curve was drawn to distinguish different patterns of bone marrow infiltration.Results There was no statistically significant difference in ADC values between the diffuse lesion in combined focal and diffuse infiltration group and the"salt-and-pepper"group(P＞0.99),and there was statistically significant difference in ADC values between the other groups(P＜0.05).The ROC curve showed that the area under the curve(AUC)for identifying focal group and the"salt-and-pepper"group was 0.889[95％confidence interval(CI)0.844-0.934],the AUC for identifying pure diffuse infiltration group and the normal appearance group was 0.968(95％CI 0.949-0.987).ADC values were able to accurately and visually differentiate between the different patterns of bone marrow infiltration.Conclusion The ADC values can be used as a quantitative tool to objectively distinguish different bone marrow infiltration patterns in MM patients.
