Objective To explore the diagnostic value of soluble C5b-9 (sC5b-9) for delayed graft function (DGF) following kidney transplantation. Methods Clinical data of 49 kidney transplant recipients who underwent sC5b-9 detection at the Second People’s Hospital of Shanxi Province between January 2024 and December 2025 were retrospectively analyzed. Recipients were divided into the DGF group (n=25) and the non-DGF group (n=24) according to the occurrence of DGF. Baseline characteristics and serum sC5b-9 levels were compared between the two groups. Receiver operating characteristic (ROC) curve analysis was performed to evaluate the diagnostic efficacy of sC5b-9 for DGF. A restricted cubic spline model was adopted to investigate the association between sC5b-9 and DGF. Results Among the 49 recipients, DGF occurred in 25 patients. Compared with the non-DGF group, the DGF group presented a higher proportion of male patients, a higher incidence of adverse transplant outcomes, and elevated final serum creatinine levels (all P<0.05). Within 30 days after transplantation, sC5b-9 concentrations were significantly higher in the DGF group than those in the non-DGF group (P<0.001). ROC analysis revealed that the area under the curve (AUC) of sC5b-9 for diagnosing DGF was 0.81, with a 95% confidence interval (CI) of 0.68-0.92, and the optimal cutoff value was 265.7 ng/mL. Recipients with elevated sC5b-9 (≥265.7 ng/mL) had a significantly higher incidence of DGF than those with low sC5b-9 levels (<265.7 ng/mL) (P<0.001). Recipients with adverse outcomes exhibited significantly higher sC5b-9 levels than those without adverse outcomes (P<0.001), and the AUC of sC5b-9 for identifying adverse outcomes was 0.82 (95%CI 0.63-0.95). A significant nonlinear correlation was observed between sC5b-9 and final serum creatinine (P<0.001). Conclusions Elevated sC5b-9 is correlated with the development of DGF after kidney transplantation and exhibits favorable diagnostic performance. It may serve as a potential biomarker for predicting early allograft dysfunction and adverse outcomes in kidney transplant recipients.

OBJECTIVE: To compare the clinical efficacy of acupuncture with yin-yang regulation method versus local acupuncture in treating chronic low back pain (CLBP) in elderly patients with lumbar disc herniation (LDH), and to evaluate the changes in the multifidus muscle before and after treatment using musculoskeletal ultrasound. METHODS: A total of 128 elderly patients with CLBP due to LDH were randomly assigned to an observation group (64 cases, 2 cases dropped out) and a control group (64 cases, 2 cases dropped out). The control group received local acupuncture at bilateral L₃-L₅ Jiaji points (EX-B2), Shenshu (BL23), Dachangshu (BL25), Weizhong (BL40), Yaoyangguan (GV3), and ashi points. The observation group received acupuncture with yin-yang regulation method, which included an abdominal protocol with Baihui (GV20), Zhongwan (CV12), Qihai (CV6), Guanyuan (CV4), bilateral Tianshu (ST25), and Dahe (KI12), etc., and a lumbar protocol with Baihui (GV20), Dazhui (GV14), Jizhong (GV6), Yaoyangguan (GV3), and ashi points, etc., alternated bilaterally. Both groups were treated once every other day, three times per week, for a total of 12 sessions. The visual analogue scale (VAS) score, Oswestry disability index (ODI) score, and the indexs of musculoskeletal ultrasound multifidus muscle (resting and functional thickness and Young's modulus values) were observed before and after treatment, and the clinical efficacy was evaluated in the two groups. RESULTS: After 1 and 4 weeks of treatment, both groups showed lower VAS scores compared to baseline (P<0.05), the VAS scores in the observation group were lower than those in the control group (P<0.001). ODI scores in both groups were decreased after 1 and 4 weeks of treatment compared to baseline (P<0.05), with a further reduction at 4 weeks of treatment compared to 1 week of treatment (P<0.05); the observation group showed lower ODI score than the control group after 1 week of treatment (P<0.001). After treatment, both groups demonstrated increased resting and functional multifidus muscle thickness bilaterally compared to baseline (P<0.01), with an increased right-side thickness change rate (P<0.01), though no significant difference was observed between groups (P>0.05). Compared to baseline, after treatment, the observation group exhibited decreased Young's modulus values for bilateral resting and functional multifidus muscle (P<0.01), while the control group showed reductions only in bilateral resting and right-side functional Young's modulus values (P<0.01). After treatment, the bilateral functional Young's modulus values in the observation group were lower than that in the control group (P<0.05), and the bilateral resting and functional changes in Young's modulus values were greater in the observation group than those in the control group (P<0.01). The overall effective rate was 93.5% (58/62) in the observation group, which was higher than 79.0% (49/62) in the control group (P<0.05). CONCLUSION Acupuncture with yin-yang regulation method effectively alleviates pain, improves functional disability, increases multifidus muscle thickness, and reduces Young's modulus values in elderly patients with CLBP due to LDH, which has superior therapeutic effect compared to local acupuncture.

Based on the theory of "three regions and sanjiao" in traditional Chinese medicine (TCM), the acupuncture-moxibustion differentiation and treatment system is explored and constructed for spasm syndrome, so as to provide a clearer guiding framework for TCM treatment of spasm syndrome. This disorder is caused essentially by the invasion of pathogenic wind, and located in brain marrow. The key regions of illness cover five zang organs and five tissues, and the core pathogenesis is associated with wind disturbance in brain marrow. In differentiation, spasm syndrome refers to overall transmission (from the upper to the lower) and local transmission (from exterior to interior). This disorder can be classified into sanjiao spasm (heart-lung spasm of the upper jiao, liver-spleen spasm of the middle jiao, and liver-kidney spasm of the lower jiao) and three-region spasm (skin-vessel spasm of the upper region, tendon-muscle spasm of the middle region, and tendon-bone spasm of the lower region). Based on "three regions and sanjiao" theory of acupuncture and moxibustion, 7 "expelling-wind" points can be selected in terms of the etiology of this disease. Baihui (GV20)-toward-Taiyang (EX-HN5) needling is applied to regulate the brain marrow, focusing on the core location of illness; and regarding the key location of illness, the combination of back-shu and front-mu points and that of jing-well and xing-spring points are adopted to regulate five zang organs. The five needling techniques (half needling, leopard-spot needling, joint needling, Hegu needling and shu needling) are used to regulate five tissues.

AIM: To investigate the effect of residual astigmatism on visual quality after phacoemulsification combined with regional refractive intraocular lens(IOL)implantation in patients with age-related cataract, and to evaluate the astigmatism inclusivity of regional refractive IOL.METHODS: Retrospective cohort study. The clinical data of 62 cases(73 eyes)of age-related cataract patients who underwent phacoemulsification combined with regional refractive IOL(Lentis Comfort LS-313 MF15)implantation from July 2020 to March 2022 at the ophthalmology department of our hospital were collected. They were grouped according to residual astigmatism at 6 mo postoperatively, taking 35 cases(40 eyes)with residual astigmatism of 0.75 D to 1.50 D as the experimental group, and 27 cases(33 eyes)with residual astigmatism ≤0.75 D as the control group. Visual acuity, defocus curves, objective visual acuity [wavefront aberrations, Strehl ratio(SR), modulation transfer functions(MTF)], subjective visual acuity(national eye institute visual function questionnaire-25), patients' satisfaction, and spectacle independence were compared between the two groups at 6 mo postoperatively.RESULTS:There was a difference in the preoperative astigmatism and the number of postoperative 6 mo residual astigmatism between the two groups(P<0.01). At 6 mo postoperatively, there was no difference in uncorrected distance, intermediate, and near visual acuity, objective visual quality, subjective visual quality, satisfaction, and spectacle independence between the two groups(P>0.05). The defocus curves showed that there was no difference in visual acuity between the two groups at all points in the +2.00 to -4.00 D defocus range of the additional spherical equivalent(P>0.05).CONCLUSION:Lentis Comfort LS-313 MF15 IOL was able to accommodate regular astigmatism of 1.50 D.

Objective To investigate whether 3D-guided cone-shaped segmentectomy can achieve comparable long-term outcomes with lobectomy for deep early-stage lung cancer with diameter≤2 cm. Methods We retrospectively screened patients with deep early-stage non-small cell lung cancer (NSCLC) with diameter≤2 cm who underwent lobectomy or segmentectomy in the First Affiliated Hospital of Nanjing Medical University from 2012 to 2018. All pulmonary segmentectomy was performed using 3D-guided cone-shaped segmentectomy with segment or subsegment as the resection unit. Univariate and multivariate regression analyses were performed by Cox proportional hazard regression model. The patients who underwent segmentectomy and lobectomy were matched 1∶1 by propensity-score matching analysis. The oncological outcomes of two groups were compared. Results Our cohort was divided into a segmentectomy group (n=222) and a lobectomy group (n=127). The age, total nodule size, solid component size and proportion of pure solid nodule in the lobectomy group were significantly higher than those in the segmentectomy group. The median follow-up time was 49 months. Surgical margins were negative in all patients. The local recurrence rate of segmentectomy was 0.45%. The disease-free survival (DFS) rate and overall survival (OS) rate of patients in the segmentectomy group were significantly better than those in the lobectomy group (5-year DFS rate: 98.64% vs. 89.77%, P<0.001; 5-year OS rate: 99.55% vs. 92.10%, P<0.001). Multivariate regression analysis showed that the differences between two groups were not significant [DFS rate: HR=0.52. 95%CI (0.11, 2.59), P=0.427; OS rate: HR=0.08. 95%CI (0.00, 3.24), P=0.179] after adjusting for other factors. After propensity score matching, 77 patients were preserved in both segmentectomy group and lobectomy group, with the mean nodule size of 1.44 cm and 1.49 cm and the mean consolidation tumor ratio (CTR) of 0.46 and 0.52, respectively. There was no statistical difference in DFS rate (P=0.640) or OS rate (P=0.310) between the two groups. Conclusion 3D-guided cone-shaped segmentectomy can be an acceptable treatment for low-grade malignant NSCLC deep in lung parenchyma with diameter≤2 cm, and its oncology effect is not inferior to lobectomy.

Objective To analyze the relationship between serum exosomal microRNA(miR)-7-5p expression levels in children with asthma and their short-term prognosis.Methods A total of 132 asthmatic children(asthma group)and 30 healthy children(control group)from Tangshan Vocational & Technical College Affiliated Hospital between October 2021 and May 2023 were included as study subjects.These asthmatic children were categorized into a good prognosis group(n=91)and a poor prognosis group(n=41)based on their Childhood Asthma Control Test results.The levels of allergy history,forced vital capacity(FVC),fractional exhaled nitric oxide(FeNO),and miR-7-5p level among groups were compared,and logistic regression analysis was conducted to identify risk factors for the short-term prognosis of asthmatic children.The Kappa test,receiver operating characteristic(ROC)curve,and mean absolute error(MAE)value were used to evaluate indicators in predicting short-term prognosis in children with asthma.Results The level of miR-7-5p in the asthma group[0.53(0.49,0.64)]was lower than that in the control group[1.03(0.97,1.10)],with significant difference(Z=8.548,P＜0.001).The poor prognosis group exhibited a higher proportion of allergy history(68.29％)and FeNO[38(36,41)ppb]levels,and lower FVC[1.86(1.84,2.05)L]and miR-7-5p levels[0.47(0.43,0.52)]compared to the good prognosis group[46.15％,35(30,40)ppb,1.94(1.87,2.06)L,0.60(0.50,0.68)],and the differences were significant(x2/Z=2.854～6.450,all P＜0.05).Multivariate logistic regression analysis revealed that a history of allergies(OR=3.388,95％CI:1.328～8.643,P=0.011)and high FeNO levels(OR=1.161,95％CI:1.064～1.267,P=0.001)were independent risk factors,while a high level of miR-7-5p(OR=0.090,95％CI:0.033～0.248,P＜0.001)was an independent protective factor for the short-term prognosis of asthmatic children.The area under the ROC curve for miR-7-5p+allergy history+FeNO in predicting the short-term prognosis of asthmatic children was 0.851,which was higher than that for miR-7-5p alone(0.851,Z=2.097,P=0.036)and allergy history+FeNO(0.726,Z=4.239,P＜0.001).The Kappa value for miR-7-5p+allergy history+FeNO was 0.67,which was higher than miR-7-5p(0.44)and allergy history+FeNO(0.41).The MAE for miR-7-5p+allergy history+FeNO was 0.022,which was lower than miR-7-5p alone(0.067)and the combination of allergy history+FeNO(0.035).Conclusion Elevated level of miR-7-5p in the serum exosomes of asthmatic children is linked to a favorable short-term prognosis.The combination of miR-7-5p,allergy history,and FeNO may have certain value in evaluating the short-term prognosis of asthmatic children.

The optimal operation room cooling source can be selected to save energy in the whole hospital life cycle ac-cording to special cooling load characteristics of specialized hospital.This paper demonstrates the energy-saving performance of the system of water-cooled and air-cooled dual cooling source based on theoretical analysis.Taking the operation room of Zhongs-han Ophthalmic Center,Sun Yat-sen University as an example,the energy consumption data is analyzed under different season and different chilled water temperature of the transformed dual cooling source operation room.It is proposed that utilizing central-ized water-cooling system may not be more energy saving than the that of individual air-cooling system during transitional season or winter,and the vertical temperature rise and cold loss of chilled water should be considered as well,providing a reference for the dual cooling source in domestic specialized operation rooms.
