ObjectiveTo study the correlations between traditional Chinese medicine （TCM） syndromes and lipid metabolism in children with Wilson disease （WD）. MethodsClinical data and lipid metabolism indicators ［total cholesterol （TC）， triglycerides （TG）， low-density lipoprotein cholesterol （LDL-C）， high-density lipoprotein cholesterol （HDL-C）， apolipoprotein A1 （ApoA1）， apolipoprotein B （ApoB）， and lipoprotein a （Lpa）］ were retrospectively collected from 341 children with WD. The clinical data were compared among WD children with different syndromes， and the correlations between TCM syndromes and lipid metabolism in children with WD were analyzed. Least absolute shrinkage and selection operator （LASSO） regression was used for variable screening， and unordered multinomial Logistic regression was employed to analyze the effects of lipid metabolism indicators on TCM syndromes. ResultsThe 341 children with WD included 121 （35.5%） children with the dampness-heat accumulation syndrome， 103 （30.2%） children with the liver-kidney Yin deficiency syndrome， 68 children with the combined phlegm and stasis syndrome， 29 children with the spleen-kidney Yang deficiency syndrome， and 20 children with the liver qi stagnation syndrome. The liver-kidney Yin deficiency syndrome， combined phlegm and stasis syndrome， and spleen-kidney Yang deficiency syndrome had correlations with the levels of lipid metabolism indicators （P<0.05）. Lipid metabolism abnormalities occurred in 232 （68.0%） children， including hypertriglyceridemia （108）， hypercholesterolemia （23）， mixed hyperlipidemia （67）， lipoprotein a-hyperlipoproteinemia （12）， and hypo-HDL-cholesterolemia （22）. The percentages of hypertriglyceridemia and hypo-HDL-cholesterolemia varied among children with different TCM syndromes （P<0.05）. Correlations existed for the liver-kidney Yin deficiency syndrome with TG， TC， and HDL-C， the combined phlegm and stasis syndrome with TG， the spleen-kidney Yang deficiency syndrome with TG， TC， and LDL-C， and the liver Qi stagnation syndrome with TC and LDL-C （P<0.05， P<0.01）. ConclusionThe TCM syndromes of children with WD are dominated by the dampness-heat accumulation syndrome and the liver-kidney Yin deficiency syndrome， and dyslipidemia in the children with WD is dominated by hypertriglyceridemia and mixed hyperlipidemia. There are different correlations between TCM syndromes and lipid metabolism indicators， among which TG， TC， LDL-C， and HDL-C could assist in identifying TCM syndromes in children with WD.

Objective To establish the finite element model of spinal canal reconstruction and internal fixation,analysis influence of spinal canal reconstruction and internal fixation on spinal stability,and verify the effectiveness and reliability of spinal canal reconstruction and internal fixation in spinal canal surgery.Methods A 30-year-old male healthy volunteer with a height of 172 cm and weight of 75 kg was selected and his lumbar CT data were collected to establish a finite element model of normal lumbar Lo3-L,and the results were compared with in vitro solid results and published finite element analysis results to verify the validity of the model.They were divided into normal group,laminectomy group and spinal canal reconstruction group according to different treatment methods.Under the same boundary fixation and physiological load conditions,six kinds of ac-tivities were performed,including forward bending,backward extension,left bending,right bending,left rotation and right rota-tion,and the changes of range of motion(ROM)of L3-L4,L4-L5 segments and overall maximum ROM of L3-L5 were analyzed under the six conditions.Results The ROM displacement range of each segment of the constructed L3-L5 finite element model was consistent with the in vitro solid results and previous literature data,which confirms the validity of the model.In L3-L4,ROM of spinal canal reconstruction group was slightly increased than that of normal group during posterior extension(＞5％dif-ference),and ROM of other conditions was similar to that of normal group(＜5％difference).ROM in laminectomy group was significantly increase than that in normal group and spinal canal reconstruction group under the condition of flexion,extension,left and right rotation.In L4-L5,ROM in spinal canal reconstruction group was similar to that in normal group(＜5％differ-ence),while ROM in laminectomy group was significantly higher than that in normal group and spinal canal reconstruction group(＞5％difference).In the overall maximum ROM of L3-L5,spinal canal reconstruction group was only slightly higher than normal group under the condition of posterior extension(＞5％difference),while laminectomy was significantly higher than normal group and spinal canal reconstruction group under the condition of anterior flexion,posterior extension,left and right rotation(＞5％difference).The changes of each segment ROM and overall ROM of L3-L5 showed laminectomy group＞spinal canal reconstruction group＞normal group.Conclusion Laminectomy could seriously affect biomechanical stability of the spine,but application of spinal canal reconstruction and internal fixation could effectively reduce ROM displacement of the responsi-ble segment of spine and maintain its biomechanical stability.

Objective To investigate the application value of arthroscopic three-approach combined with elliptical tunnel technique in anterior cruciate ligament(ACL)reconstruction.Methods A prospective analysis was conducted on 104 patients with ACL injury admitted to our hospital.They were randomly divided into the observation group and the control group according to a random number table method,with 52 cases in each group.All patients in both groups underwent ACL reconstruction.The patients in the observation group were treated with the arthroscopic three-approach combined with elliptical tunnel technique,while the patients in the control group were treated with the traditional anteromedial approach and elliptical tunnel technique.The surgical related indicators,parameters of postoperative bone tunnel positioning,postoperative graft maturation,knee stability(Lachman test),Lysholm score of knee function,and complications of patients were compared between the two groups.Results The time of getting out of bed with crutches,time of walking without crutches and recovery time of patients in the observation group were shorter than those in the control group(P<0.05).The A/B value of patients in the observation group was greater than that in the control group,and the a/c and α were smaller than those in the control group(P<0.05).The signal/noise quotient(SNQ)of the proximal,middle,and distal grafts 6 and 12 months after surgery of patients in the observation group were lower than those in the control group(P<0.05).At 6 months postoperatively,the knee stability of patients in the observation group was better than that in the control group,and the Lysholm score of knee function was higher than that in the control group(P<0.05).There was no significant difference in the incidence of postoperative complications between the two groups(P>0.05).Conclusion Arthroscopic three-approach combined with elliptical tunnel technique can improve the morphology of bone tunnel,promote graft maturation,shorten postoperative recovery process,and improve knee function in ACL reconstruction,with high safety.

Objective To compare the efficacy of renal proximal renal artery denervation(pRDN)and full-length renal artery denervation(fRDN)for treatment of hypertension.Methods Fifty-six hypertensive patients were enrolled and randomly assigned to full-length renal artery denervation group(n=25)and proximal renal artery denervation group(n=31).After the procedure,24-hour ambulatory blood pressure monitoring(24 h-ABPM)at 6 months and office blood pressure at 12 months was recorded for statistical analysis.Results The blood pressure at follow-up reduced significantly in both groups,while there was no significant difference between groups.The baseline office blood pressure in fRDN group and pRDN group was(180±15)/(104±10)mmHg and(180±12)/(103±8)mmHg,respectively,which decreased to(142±9)/(82±7)mmHg and(143±10)/(83±6)mmHg at 12 months postoperatively(P＜0.001 within groups and P＞0.05 between groups).The baseline 24 h-ABPM in the two groups was(162±13)/(95±8)mmHg and(160±12)/(94±8)mmHg,respectively,which decreased to(142±11)/(83±7)mmHg and(141±8)/(81±7)mmHg at 6 months postoperatively(P＜0.001 within groups and P＞0.05 between groups).However,there was no significant difference in the reduction of office blood pressure and ambulatory blood pressure between the two groups.No treatment-related adverse events were observed.Conclusions pRDN has similar antihypertensive effect to fRDN.

This article provides a review of domestic and international research on nursing-sensitive quality indicators (NSQIs) and evaluation systems for acute poisoning patients. It organizes the indicators into three dimensions based on the "structure-process-outcome" framework. The need for establishing a unified, comprehensive, and nationally suitable system of NSQIs in China is emphasized to standardize nursing practices and improve the monitoring of care quality. Although existing indicators possess some scientific validity, they often overlap with emergency nursing quality evaluation systems or are limited to specific types of poisoning. In addition, large-scale clinical trials to test their practical application and accessibility have yet to be conducted. This review aims to consolidate and analyze NSQIs for acute poisoning patients and provide a foundation and reference for improving the quality of nursing care for these patients.

Objective:To investigate the efficiency and safety of the pulsatile GnRH therapy in the treatment of male congeni-tal hypogonadotropic hypogonadism(CHH).Methods:We retrospectively analyzed the clinical data on 45 CHH males treated by pulsatile GnRH therapy in our hospital from January 2013 to March 2023.We treated the patients with gonadorelin at 7-15 μg,one pulse/90 min,and followed them up every month in the first 3 months and then every 3 to 6 months after treatment,for an average of 19.1±4.3 months,during which we recorded the height,body weight,penile length,testis volume,Tanner stages,levels of FSH,LH and T,semen parameters and adverse reactions of the patients,followed by comparison of the data obtained with the baseline.Results:The levels of FSH,LH and T of the patients were dramatically elevated after treatment(P<0.01).The T level of the6 ca-ses of cryptorchidism,however,failed to reach the normal value within 18.2±8.6 months of follow-up.Significant improvement was seen in the external genitalia and secondary sexual characteristics of all the patients,and spermatogenesis was observed in the semen in 33 cases(73.3% ),with a mean sperm concentration of(18.2±6.2)106/ml,sperm progressive motility of(19.7±6.5)%,and semen volume of(1.8±0.6)ml.Eight of the cases achieved natural fertility,and another 3 achieved childbirth by assisted re-productive technology.As for adverse events,gynecomastia was observed in 8,subcutaneous induration in 6,and allergic reaction to therapeutic agent in 3 cases.Conclusion:Pulsatile GnRH therapy is an effective and safe strategy for male CHH.However,clini-cians should choose appropriate approaches to different individual cases.

Objective:To assess the efficacy, safety, and related prognostic factors associated with the P-GemDOx regimen as a first-line treatment for patients with early-stage extranodal natural killer (NK) /T cell lymphoma (ENKTL) .Methods:A retrospective analysis was performed on sixty early-stage ENKTL patients treated with the P-GemDOx regimen who were admitted to the First Affiliated Hospital of Nanjing Medical University between August 2015 and May 2021. The Chi-square test or Fisher's exact test was used to compare group differences, and the Log-rank test was used to compare the differences in survival. Survival outcomes and prognostic factors were examined.Results:After completing 4 to 6 cycles of P-GemDOx chemotherapy, the overall response rate (ORR) was 88.3%, with forty-six patients (76.7% ) achieving complete response (CR). The 4-year progression-free survival (PFS) and overall survival (OS) rates were (66.3±7.1) % and (79.5±6.0) %, respectively. According to the PINK/PINK-E model, there was no significant difference in survival outcomes among risk groups. 23.3% of patients experienced progression of disease within 24 months (POD<24). OS estimates differed significantly ( P<0.001) between the POD<24 group ( n=14) and the POD≥24 group ( n=46). Analysis showed that SUVmax > 12.8 at diagnosis, non-single nasal cavity infiltration, and response less than CR after 4–6 cycles all had a significant association with POD24. We used these data as the basis for predicting POD<24 international prognostic index (POD24-IPI). Patients were stratified into low-risk (no risk factors), intermediate-risk (one risk factor), or high risk (two or three risk factors). These groups were associated with 4-year OS rate of 100%, (85.6±9.7) %, and (65.0±10.2) %, respectively ( P=0.014). The P-GemDOx regimen was well tolerated, with hematological toxicity being the main side effect. Conclusion:This study demonstrated that the P-GemDOx regimen is effective and safe in the first-line treatment of early-stage ENKTL, and POD24-IPI is a promising prognostic model.

Objective:To investigate the efficacy and safety of orelabrutinib combined with R-CHOP in the treatment of MCD subtype diffuse large B cell lymphoma (DLBCL) .Methods:Twenty-three MCD subtype patients whose gene-subtype classification was based on baseline tumor tissue and/or baseline plasma using the LymphGen algorithm from June 2022 to June 2023 in the First Affiliated Hospital of Nanjing Medical University were retrospectively enrolled in the analysis. All patients were treated with R-CHOP or R-miniCHOP in Course 1, OR-CHOP or OR-miniCHOP (21 days for one course) in Courses 2-6, and R-monotherapy in Courses 7-8.Results:Of the 23 patients, the median age was 58 years (range: 30-81 years), and 11 (47.8% ) aged >60 years. Fifteen cases (65.2% ) had international prognostic index (IPI) scores of 3 to 5. The top 10 mutated genes in the gDNA tissues were PIM1 (78.3% ), MYD88 (69.6% ), ETV6 (43.5% ), BTG1 (39.1% ), CD79B (43.5% ), HIST1H1E (39.1% ), BTG2 (34.8% ), KMT2D (30.4% ), CD58 (26.1% ), and CDKN2B (21.7% ). The consistency rate of the tissue and plasma mutations was 80%, while the baseline plasma ctDNA burden was closely correlated with the LDH levels and IPI scores ( P<0.05). All patients received 5 courses of OR-CHOP regimens. The mid-term (after 3 courses) evaluation showed that the overall response rate (ORR) was 100% (23/23), with 22 patients (95.65% ) achieving complete remission (CR), and 1 patient (4.35% ) achieving partial remission (PR). The ORR after the end of treatment (EOT) was 95.65% (22/23). Moreover, 21 patients (91.30% ) obtained CR, 1 patient (4.35% ) obtained PR, and 1 patient (4.35% ) obtained progression disease (PD). Of the 21 patients who had the dynamic EOT-ctDNA burden, only four patients (19.0% ) did not achieve EOT-ctDNA clearance, while the other 17 patients (81.0% ) achieved EOT-ctDNA clearance. The median follow-up time was 20.8 (15.3-30.0) months, while the median progression-free survival (PFS) and overall survival (OS) were not reached. The 2-year PFS rate was 71.8% (95% CI 54.7% -94.2% ), while the 2-year OS rate was 91.3% (95% CI 80.5% -100.0% ). Furthermore, the OR-CHOP regimen was generally well tolerated during clinical use, with hematological toxicity being the main adverse effect. Conclusion:This study revealed that the OR-CHOP regimen can be used as an effective and safe first-line treatment for MCD subtype DLBCL.

Objective:To observe the intervention effect of aerobic Baduanjin exercise combined with treadmill train-ing on chronic obstructive pulmonary disease(COPD)complicated chronic heart failure(CHF).Methods:A total of 180 COPD+CHF patients who were treated in Mianyang Central Hospital from January 2019 to June 2021 were selected.They were equally divided into control group(basic treatment and intervention)and experimental group(received aerobic Baduanjin exercise combined with treadmill training based on control group)by random number table method,both groups were intervened for 12 weeks.COPD assessment test(CAT)score,left ventricular ejec-tion fraction(LVEF),left ventricular end systolic volume(LVESV),left ventricular end diastolic volume(LV-EDV),scores of modified medical research council(mMRC)and Minnesota living with heart failure questionnaire(MLHFQ)were compared between two groups before,4,8 and 12 weeks after intervention.Results:During 12-week intervention,CAT score,LVESV,LVEDV,scores of mMRC and MLHFQ showed a gradual decreasing trend,while LVEF showed a gradual increasing trend in two groups,P＜0.05 or＜0.01.Compared with control group after 12-week intervention,there were significant reductions in CAT score[(17.47±3.96)points vs.(13.36±3.42)points],LVEDV[(139.44±7.12)ml vs.(131.74±6.47)ml],LVESV[(81.84±8.54)ml vs.(74.29±9.18)ml],scores of mMRC[(1.67±0.47)points vs.(1.42±0.50)points],each dimension and total score of MLHFQ[(40.07±6.86)points vs.(32.54±6.61)points],and significant rise in LVEF[(41.29±4.76)％vs.(44.56±4.42)％]in experimental group(P＜0.001 all).Conclusion:Aerobic Baduanjin exercise combined with treadmill training based on basic treatment can significantly improve cardiopulmonary function,re-lieve dyspnea and improve quality of life in COPD+CHF patients,which is worth promoting.

Objective To compare the oral cleansing effects of the microbubble toothbrush and the conventional pulsed oral irrigator to provide references for users.Methods Ninety identical 3D-printed resin tooth models were grouped and subjected to repeated experiments,which were divided randomly into five groups including a microbubble toothbrush high-speed gear(GN-H)group,a microbubble toothbrush medium-speed gear(GN-M)group,a microbubble low-speed gear(GN-L)group,a conventional pulsed oral irrigator high-speed gear(W-H)group and a conventional pulsed oral irrigator low-speed gear(W-L)group,with 18 teeth in each group.The cleansing effects of the microbubble toothbrush and the conventional pulsed oral irrigator were evaluated in terms of irrigating strength and abilities for eliminating plaque and debris.Results Both the two types of water flossers were provided with high irrigating strength and effectively reduced plaque and debris on tooth surfaces,and the GN-H,GN-M and GN-L groups behaved better significantly than the remained groups.The order of the five groups was GN-H group＞GN-M group＞W-H group＞GN-L group＞W-L group for irrigating strength,GN-H group＞GN-M group＞GN-L group＞W-H group＞W-L group for plaque removal,GN-H group＞GN-M group＞W-H group＞GN-L group＞W-L group for debris removal,with all the differences being statistically significant(P＜0.05).Conclusion Both the two types of water flossers remove plaque and debris effectively,while the microbubble toothbrush gains advantages over the conventional pulsed oral irrigator.[Chinese Medical Equipment Journal,2024,45(9):67-72]
