Coexisting Magnetism, Ferroelectric, and Ferrovalley Multiferroic in Stacking-Dependent Two-Dimensional Materials.

Two-dimensional (2D) multiferroic materials have widespread application prospects in facilitating the integration and miniaturization of nanodevices. However, the magnetic, ferroelectric, and ferrovalley properties in one 2D material are rarely coupled. Here, we propose a mechanism for manipulating magnetism, ferroelectric, and valley polarization by interlayer sliding in a 2D bilayer material. Monolayer GdI2 is a ferromagnetic semiconductor with a valley polarization of up to 155.5 meV. More interestingly, the magnetism and valley polarization of bilayer GdI2 can be strongly coupled by sliding ferroelectricity, making these tunable and reversible. In addition, we uncover the microscopic mechanism of the magnetic phase transition by a spin Hamiltonian and electron hopping between layers. Our findings offer a new direction for investigating 2D multiferroic devices with implications for next-generation electronic, valleytronic, and spintronic devices.

Chiral photon blockade in the spinning Kerr resonator.

We propose how to achieve chiral photon blockade by spinning a nonlinear optical resonator. We show that by driving such a device at a fixed direction, completely different quantum effects can emerge for the counter-propagating optical modes, due to the spinning-induced breaking of time-reversal symmetry, which otherwise is unattainable for the same device in the static regime. Also, we find that in comparison with the static case, robust non-classical correlations against random backscattering losses can be achieved for such a quantum chiral system. Our work, extending previous works on the spontaneous breaking of optical chiral symmetry from the classical to purely quantum regimes, can stimulate more efforts towards making and utilizing various chiral quantum effects, including applications for chiral quantum networks or noise-tolerant quantum sensors.

Multiple-photon bundle emission in the n-photon Jaynes-Cummings model.

We study the multiple-photon bundle emission in the n-photon Jaynes-Cummings model composed of a two-level system coupled to a single-mode optical field via the n-photon exciting process. Here, the two-level system is strongly driven by a near-resonant monochromatic field, and hence the system can work in the Mollow regime, in which a super-Rabi oscillation between the zero-photon state and the n-photon state can take place under proper resonant conditions. We calculate the photon number populations and the standard equal-time high-order correlation functions, and find that the multiple-photon bundle emission can occur in this system. The multiple-photon bundle emission is also confirmed by investigating the quantum trajectories of the state populations and both the standard and generalized time-delay second-order correlation functions for multiple-photon bundle. Our work paves the way towards the study of multiple-photon quantum coherent devices, with potential application in quantum information sciences and technologies.

Real-world applications of PARPi maintenance therapy for recurrent ovarian cancer: A single-center study in China.

OBJECTIVE: To assess the actual clinical application of poly (adenosine diphosphate-ribose) polymerase inhibitor (PARPi) maintenance therapy in Chinese patients with recurrent ovarian cancer, and to explore prognostic factors associated with progression-free survival (PFS). METHODS: We retrospectively assessed real-world clinical data from our hospital using the inclusion and exclusion criteria of representative randomized controlled trials, analyzed the prognosis, and performed univariate and multivariate analyses of prognostic factors. RESULTS: Between 2019 and 2022, the proportion of platinum-sensitive recurrence ovarian cancer patients who received PARPi maintenance therapy increased to 29.6%, 53.3%, 43.8% and 62.2%, respectively, each year. A total of 48 patients were included in the prognostic analysis, of which 32 and 16 received olaparib and niraparib, respectively. Using the criteria of the Study19 and SOLO2 studies, the olaparib group in our patients had coincidence rates of 56.3% and 18.8%, respectively. Using the criteria of the NOVA and NORA studies, the niraparib group had coincidence rates of 31.3% and 37.5%, respectively. Median PFS was 26.1 months (95% CI 20.2-32.1). Response to primary therapy was an independent prognostic factor for PFS (relative risk, 3.248; 95% CI 1.081-9.757, P = 0.036). CONCLUSIONS: PARPi maintenance therapy was also effective in real world applications. Complete response (CR) to primary therapy was an independent factor favorably affecting PFS. Therefore, primary treatment choices aimed at optimal cytoreduction during primary surgery and improving the CR rate should still be considered, which positively affects the long-term prognosis of patients in the new treatment mode.

Percutaneous vertebral augmentation using drill rotation for osteoporotic vertebral compression fractures with intravertebral vacuum cleft.

OBJECTIVE: To evaluate the efficacy of a new technique of percutaneous vertebral augmentation (PVA): drill rotation-cement injected under vacuum aspiration (DR-CIVAS) for vertebral compression fractures (OVCFs) with intravertebral vacuum cleft (IVC) sign. MATERIALS AND METHODS: A retrospective study was conducted in 46 consecutive patients with OVCFs and IVC signs, who underwent PVA using DR-CIVAS (n = 22, DR-CIVAS group) or traditional technique without DR-CIVAS (n = 24, control group). The pre- and postoperative vertebral height and wedge angle change and visual analog scale (VAS), the volume of cement injected, incidences of cement leakage, and subsequent new vertebral compression fractures were evaluated between the two groups. RESULTS: No significant difference was found in cement leakage incidences, pre- and postoperative VAS scores, vertebral height, and wedge angle change between the two groups. The mean cement volume was significantly higher (P < 0.001) in DR-CIVAS group (4.87 mL) than in the control group (3.58 mL). Of the 22 patients in DR-CIVAS group, the subsequent fractures occurred in 2 cases (9.1%) located in the nonadjacent levels. In the control group, the subsequent fractures occurred in 6 cases (25.0%) located in the adjacent level (n = 1) and the augmented levels (n = 5). Although DR-CIVAS group did not demonstrate a statistical reduction of the incidence of subsequent fractures (P = 0.25), the subgroup analysis revealed that subsequent fractures frequently involved the augmented level in the control group (P = 0.04). CONCLUSIONS: PVA with DR-CIVAS technique is effective for OVCFs with IVC sign, with lower incidences of subsequent new vertebral compression fractures in the augmented vertebra.

[Development of resources, technologies and services at the China Zebrafish Resource Center].

With the rapid growth of the Chinese zebrafish community, there is an increasing demand for various types of zebrafish-related resources and technologies. The China Zebrafish Resource Center (CZRC, web: http://zfish.cn) was established at the Institute of Hydrobiology (IHB), Chinese Academy of Sciences (CAS) in 2012. Till now, CZRC has built the largest zebrafish aquaculture unit in China, organized a resource bank containing more than 1200 zebrafish lines and more than 10 000 frozen sperm samples, among which over 200 mutant and transgenic lines were generated by CZRC. CZRC has established several technical supporting platforms, such as the zebrafish husbandry and health control program of international standard, a high-efficient gene manipulation technology platform, and a stable and efficient sperm cryopreservation technology platform. The main task of CZRC is to provide different types of services to zebrafish investigators in China and worldwide, such as resource services (e.g. zebrafish lines), technical services (e.g. gene knockout) and transgenic services, consultancy services (e.g. zebrafish husbandry and health consultation), and conference services [e.g. holding regular technical training courses and biennale Chinese Zebrafish Principal Investigator Meeting (CZPM)]. After five years' development, CZRC is now recognized as one of the three major resource centers in the global zebrafish community.

Comparison of percutaneous long bone cementoplasty with or without embedding a cement-filled catheter for painful long bone metastases with impending fracture.

OBJECTIVE: To compare the efficacy of percutaneous long bone cementoplasty (PLBC) with and without embedding a cement-filled catheter in the medullary canal (ECFC) for painful long bone metastases with impending fracture. METHODS: A retrospective study was conducted in 36 consecutive patients undergoing PLBC and ECFC combination (n = 17, group A) or PLBC alone (n = 19, group B). All patients had a high risk of impending fracture in the long bone based on Mirels' scoring system. Clinical effects were evaluated using both a pre- and a postoperative visual analogue scale (VAS) and Karnofsky performance scale (KPS). RESULTS: Overall pain relief rate with excellent (VAS 0-2) and good (VAS 2.5-4.5) results during follow-up was significantly higher in group A than in group B (88.2 % vs. 57.9 %, P<0.05). The average VAS and KPS changes in group A were significantly higher than those in group B at 1, 3 and 6 months postoperatively (P<0.05). Also, the rate of fractures of the treated long bone in group A was significantly lower than that in group B (P<0.05). CONCLUSIONS: Combined PLBC and ECFC is a safe and effective procedure for long bone metastases with impending fracture. KEY POINTS: • Metastases in long bones may cause pain and subsequent pathological fractures. • Cementoplasty resulted in significant pain relief in patients with long bone metastases. • Combination of PLBC and ECFC may reduce the incidence of fractures.

An Alkaline-Stable, Metal Hydroxide Mimicking Metal-Organic Framework for Efficient Electrocatalytic Oxygen Evolution.

Postsynthetic ion exchange of [Co2(µ-Cl)2(btta)] (MAF-X27-Cl, H2bbta =1H,5H-benzo(1,2-d:4,5-d')bistriazole) possessing open metal sites on its pore surface yields a material [Co2(µ-OH)2(bbta)] (MAF-X27-OH) functionalized by both open metal sites and hydroxide ligands, giving drastically improved electrocatalytic activities for the oxygen evolution reaction (an overpotential of 292 mV at 10.0 mA cm(-2) in 1.0 M KOH solution). Isotope tracing experiments further confirm that the hydroxide ligands are involved in the OER process to provide a low-energy intraframework coupling pathway.

[Anti-inflammatory effect of recombinant human kallistatin in ulcerative colitis of mice].

This study was designed to evaluate the anti-inflammatory effect of recombinant human kallistatin (Kal) on ulcerative colitis (UC) in the mouse model. Acute colitis was induced by administration of 4% dextran sodium suffate (DSS) to KM mice for 7 days. The mice were then randomized into 5 groups: model control, Kal 0.2 mg·kg(-1)·d(-1), 1.0 mg·kg(-1)·d(-1) and 2.0 mg·kg-1·d(-1) group, salazosulfapyridine (SASP) group. Ten age-matched normal KM mouse were administered with saline in the normal control. The weight, colon length, inflammation factor (MPO/SOD/MDA) and TNF-α/IL-10 levels among the five groups of mice were determined. The results showed that histological index score and MPO/MDA/TNF-α levels of high-dose Kal treatment group and SASP group were significantly lower compared with the model group (P < 0.01), but the weight, colon length, IL-10 level and SOD activity were significant higher than the model group (P < 0.01), approaching the normal group. These parameters showed that Kal can significantly relieve the UC state in a dose-dependent manner. This study demonstrates that Kal significantly remits UC in mice, and participates in the regulation of inflammatory cytokines TNF-α/IL-10 levels and has some antioxidant activity.

Effects of long-term exposure to air pollution on natural-cause mortality: an analysis of 22 European cohorts within the multicentre ESCAPE project.

BACKGROUND: Few studies on long-term exposure to air pollution and mortality have been reported from Europe. Within the multicentre European Study of Cohorts for Air Pollution Effects (ESCAPE), we aimed to investigate the association between natural-cause mortality and long-term exposure to several air pollutants. METHODS: We used data from 22 European cohort studies, which created a total study population of 367,251 participants. All cohorts were general population samples, although some were restricted to one sex only. With a strictly standardised protocol, we assessed residential exposure to air pollutants as annual average concentrations of particulate matter (PM) with diameters of less than 2.5 µm (PM2.5), less than 10 µm (PM10), and between 10 µm and 2.5 µm (PMcoarse), PM2.5 absorbance, and annual average concentrations of nitrogen oxides (NO2 and NOx), with land use regression models. We also investigated two traffic intensity variables-traffic intensity on the nearest road (vehicles per day) and total traffic load on all major roads within a 100 m buffer. We did cohort-specific statistical analyses using confounder models with increasing adjustment for confounder variables, and Cox proportional hazards models with a common protocol. We obtained pooled effect estimates through a random-effects meta-analysis. FINDINGS: The total study population consisted of 367,251 participants who contributed 5,118,039 person-years at risk (average follow-up 13.9 years), of whom 29,076 died from a natural cause during follow-up. A significantly increased hazard ratio (HR) for PM2.5 of 1.07 (95% CI 1.02-1.13) per 5 µg/m(3) was recorded. No heterogeneity was noted between individual cohort effect estimates (I(2) p value=0.95). HRs for PM2.5 remained significantly raised even when we included only participants exposed to pollutant concentrations lower than the European annual mean limit value of 25 µg/m(3) (HR 1.06, 95% CI 1.00-1.12) or below 20 µg/m(3) (1.07, 1.01-1.13). INTERPRETATION: Long-term exposure to fine particulate air pollution was associated with natural-cause mortality, even within concentration ranges well below the present European annual mean limit value.

Air pollution and nonmalignant respiratory mortality in 16 cohorts within the ESCAPE project.

RATIONALE: Prospective cohort studies have shown that chronic exposure to particulate matter and traffic-related air pollution is associated with reduced survival. However, the effects on nonmalignant respiratory mortality are less studied, and the data reported are less consistent. OBJECTIVES: We have investigated the relationship of long-term exposure to air pollution and nonmalignant respiratory mortality in 16 cohorts with individual level data within the multicenter European Study of Cohorts for Air Pollution Effects (ESCAPE). METHODS: Data from 16 ongoing cohort studies from Europe were used. The total number of subjects was 307,553. There were 1,559 respiratory deaths during follow-up. MEASUREMENTS AND MAIN RESULTS: Air pollution exposure was estimated by land use regression models at the baseline residential addresses of study participants and traffic-proximity variables were derived from geographical databases following a standardized procedure within the ESCAPE study. Cohort-specific hazard ratios obtained by Cox proportional hazard models from standardized individual cohort analyses were combined using metaanalyses. We found no significant associations between air pollution exposure and nonmalignant respiratory mortality. Most hazard ratios were slightly below unity, with the exception of the traffic-proximity indicators. CONCLUSIONS: In this study of 16 cohorts, there was no association between air pollution exposure and nonmalignant respiratory mortality.

Long-term exposure to air pollution and cardiovascular mortality: an analysis of 22 European cohorts.

BACKGROUND: Air pollution has been associated with cardiovascular mortality, but it remains unclear as to whether specific pollutants are related to specific cardiovascular causes of death. Within the multicenter European Study of Cohorts for Air Pollution Effects (ESCAPE), we investigated the associations of long-term exposure to several air pollutants with all cardiovascular disease (CVD) mortality, as well as with specific cardiovascular causes of death. METHODS: Data from 22 European cohort studies were used. Using a standardized protocol, study area-specific air pollution exposure at the residential address was characterized as annual average concentrations of the following: nitrogen oxides (NO2 and NOx); particles with diameters of less than 2.5 µm (PM2.5), less than 10 µm (PM10), and 10 µm to 2.5 µm (PMcoarse); PM2.5 absorbance estimated by land-use regression models; and traffic indicators. We applied cohort-specific Cox proportional hazards models using a standardized protocol. Random-effects meta-analysis was used to obtain pooled effect estimates. RESULTS: The total study population consisted of 367,383 participants, with 9994 deaths from CVD (including 4,992 from ischemic heart disease, 2264 from myocardial infarction, and 2484 from cerebrovascular disease). All hazard ratios were approximately 1.0, except for particle mass and cerebrovascular disease mortality; for PM2.5, the hazard ratio was 1.21 (95% confidence interval = 0.87-1.69) per 5 µg/m and for PM10, 1.22 (0.91-1.63) per 10 µg/m. CONCLUSION: In a joint analysis of data from 22 European cohorts, most hazard ratios for the association of air pollutants with mortality from overall CVD and with specific CVDs were approximately 1.0, with the exception of particulate mass and cerebrovascular disease mortality for which there was suggestive evidence for an association.

Growth inhibitory effect of KYKZL-1 on Hep G2 cells via inhibition of AA metabolites and caspase-3 pathway and cell cycle arrest.

KYKZL-1, a newly synthesized compound with COX/5-LOX dual inhibition, was subjected to the inhibitory activity test on Hep G2 growth. We found that KYKZL-1 inhibited the growth of Hep G2 cells via inducing apoptosis. Further studies showed that KYKZL-1 activated caspase-3 through cytochrome c release from mitochondria and down regulation of Bcl-2/Bax ratio and reduced the high level of COX-2 and 5-LOX. As shown in its anti-inflammatory effect, KYKZL-1 also exhibited inhibitory effect on the PGE2 and LTB4 production in Hep G2 cells. Accordingly, exogenous addition of PGE2 or LTB4 reversed the decreases in cell viability. In addition, KYKZL-1 caused cell cycle arrest at the S-G2 checkpoint via the activation of p21(CIP1) protein and down-regulation of cyclin A expression. These data indicate that the growth inhibitory effect of KYKZL-1 is associated with inhibition of AA metabolites and caspase-3 pathway and cell cycle arrest. Combined with our previous findings, KYKZL-1 exhibiting COX/5-LOX inhibition may be a promising potential agent not only for inflammation control but also for cancer prevention/therapy with an enhanced gastric safety profile.

Cementoplasty for managing painful bone metastases outside the spine.

OBJECTIVE: To illustrate the effect of treatment with cementoplasty in patients with painful bone metastases in the extraspinal region. METHODS: A retrospective study was conducted to review 51 consecutive patients who underwent cementoplasty under CT or fluoroscopic guidance, a total of 65 lesions involving the ilium, ischium, pubis, acetabulum, humeral, femur and tibia. In 5 patients with a high risk of impending fracture in long bones based on Mirels' scoring system, an innovative technique using a cement-filled catheter was applied. The clinical effects were evaluated using the visual analogue scale (VAS) preoperatively and postoperatively. RESULTS: All patients were treated successfully with a satisfying resolution of painful symptoms at 3 months' follow-up. Cement leakage was found in 8 lesions without any symptoms. VAS scores decreased from 8.19 ± 1.1 preoperatively to 4.94 ± 1.6 at 3 days, 3.41 ± 2.1 at 1 month and 3.02 ± 1.9 at 3 months postoperatively. There was a significant difference between the mean preoperative baseline score and the mean score at all of the postoperative follow-up points (P < 0.01). CONCLUSIONS: Cementoplasty is an effective technique for treating painful bone metastases in extraspinal regions, which is a valuable, minimally invasive, method that allows reduction of pain and improvement of patients' quality of life. KEY POINTS: • Metastases in long bones may cause pain and subsequent pathological fractures. • Cement-filled catheter resulted in a fixation effect to prevent pathological fractures. • Cementoplasty resulted in significant pain relief in patients with extraspinal metastases.

Percutaneous vertebroplasty for painful spinal metastasis with epidural encroachment.

BACKGROUND AND OBJECTIVES: Spinal metastasis with epidural encroachment is regarded by several authors to be a contraindication to percutaneous vertebroplasty (PVP) because of the risk of increasing symptomatic leakage of cement. This analysis aims to evaluate the safety and efficacy of PVP in patients with painful spinal metastasis and encroachment of epidural space. METHODS: A retrospective study was conducted to review 43 consecutive patients with spinal metastasis that underwent PVP, for a total of 69 affected levels. All patients had at least 1 level associated with epidural encroachment related to metastasis. Among these patients, 14 had signs of spinal cord or cauda equina compression. Pain intensity was scored on a visual-analog scale (VAS). The analgesic efficacy was defined as at least 50% improvement in pain score as compared with the pre-procedure baseline and post-procedure. Clinical improvement of neurological compressive symptoms was defined as a decrease in ASIA impairment scale from baseline of 1 point or more. RESULTS: The analgesic efficacy was achieved in 89.7% of survival patients at 1 month, 87.5% at 3 months, 86.9% at 6 months, and 84.6% at 1 year. Small amount cement leakages were detected in 69.6% of treated levels without clinical complications. No deterioration of spinal cord or cauda equina compression symptoms was observed after a PVP in any patients. The different grade of epidural encroachment of the lesions was not correlated with filling volume or extraosseous leakage (P > 0.05). The treated levels with epidural encroachment showed a statistically significant relationship to spinal-canal leakage (P < 0.05). CONCLUSIONS: PVP can be performed safely and effectively in patients with painful spinal metastasis and epidural encroachment.

[Adeno-associated vector mediated intracellular biological activity of human Kallistatin].

Human tissue kallikrein-binding protein (Kallistatin, KAL), a secretory protein that participates in the regulation of multiple signaling pathways by binding to the extracellular receptor, however, at present has not been reported about the intracellular activity, and whether it has the similar biological activity with extracellular activity. Here we constructed no signal peptide KAL (NSK) into the adeno-associated virus vector to explore the intracellular activity of KAL. Both the endothelial cell and lung cancer cells could express KAL, but not secreted after rAAV2-NSK transfection. The proliferation and migration of human umbilical vein endothelial cells (HUVECs) were inhibited, but the apoptosis rate was not affected. The proliferation rates, mobility and tubule formation of all the three tested lung cancer cells, such as NCI-H446, NCI-H460 and A549, were inhibited to different extents. This cellular study not only confirmed the intracellular activity, but also suggested it may serve as a kind of "balance factor" in multi-targeted controlling, which may provide a new train of thoughts to explain the regulatory contradiction in PI3K-Akt signaling pathways by KAL.

Air pollution and lung cancer incidence in 17 European cohorts: prospective analyses from the European Study of Cohorts for Air Pollution Effects (ESCAPE).

BACKGROUND: Ambient air pollution is suspected to cause lung cancer. We aimed to assess the association between long-term exposure to ambient air pollution and lung cancer incidence in European populations. METHODS: This prospective analysis of data obtained by the European Study of Cohorts for Air Pollution Effects used data from 17 cohort studies based in nine European countries. Baseline addresses were geocoded and we assessed air pollution by land-use regression models for particulate matter (PM) with diameter of less than 10 µm (PM10), less than 2·5 µm (PM2·5), and between 2·5 and 10 µm (PMcoarse), soot (PM2·5absorbance), nitrogen oxides, and two traffic indicators. We used Cox regression models with adjustment for potential confounders for cohort-specific analyses and random effects models for meta-analyses. FINDINGS: The 312 944 cohort members contributed 4 013 131 person-years at risk. During follow-up (mean 12·8 years), 2095 incident lung cancer cases were diagnosed. The meta-analyses showed a statistically significant association between risk for lung cancer and PM10 (hazard ratio [HR] 1·22 [95% CI 1·03-1·45] per 10 µg/m(3)). For PM2·5 the HR was 1·18 (0·96-1·46) per 5 µg/m(3). The same increments of PM10 and PM2·5 were associated with HRs for adenocarcinomas of the lung of 1·51 (1·10-2·08) and 1·55 (1·05-2·29), respectively. An increase in road traffic of 4000 vehicle-km per day within 100 m of the residence was associated with an HR for lung cancer of 1·09 (0·99-1·21). The results showed no association between lung cancer and nitrogen oxides concentration (HR 1·01 [0·95-1·07] per 20 µg/m(3)) or traffic intensity on the nearest street (HR 1·00 [0·97-1·04] per 5000 vehicles per day). INTERPRETATION: Particulate matter air pollution contributes to lung cancer incidence in Europe. FUNDING: European Community's Seventh Framework Programme.

Clinical Efficacy of Percutaneous Osteoplasty Under Fluoroscopy and Cone-Beam CT Guidance for Painful Sternal Metastases: A Case Series.

Background: Although percutaneous osteoplasty (POP) has been widely accepted and is now being performed for the treatment of painful bone metastases outside the spine. It is emerging as one of the most promising procedures for patients with painful bone metastasis who are unsuitable for surgery or who show resistance to radiotherapy and/or analgesic therapies. However, there are only scarce reports regarding osteoplasty in painful sternal metastases. Subjects and Method: We report four patients with sternal metastases suffered with severe pain of anterior chest wall. The original tumors included lung cancer and thyroid cancer. For the initially pain medication failing, all the four patients received POP procedure under fluoroscopic and cone-beam CT (CBCT) guidance, and obtained satisfying resolution of painful symptoms at 6-month postop follow-up. Conclusion: POP is a safe and effective treatment for pain caused by metastatic bone tumors in the sternum. In practice, however, percutaneous puncture of pathologic sternal fractures can be a challenge because of the long flat contour and the defacement by lytic tumor of bony landmarks. We find that the use of fluoroscopic and CBCT can facilitate POP for flat bone fractures with displacing the trajectory planning, needle advancement, and cement delivery in time.

Lymphovenous anastomosis and complex decongestive therapy for severe deformed lymphedema with recurrent infection: A case report.

BACKGROUND: Lower extremity lymphedema is a common complication following treatment for gynecological malignancies. Its incidence rate can reach up to 70%, affecting ~20 million people worldwide. However, specialized treatment centers are scarce, and there is a lack of consensus on treatment approaches. Furthermore, there are even fewer reports on the systematic and effective treatment of severe lymphedema with malformations. Effective management of this condition remains a significant challenge for clinicians. CASE SUMMARY: A 40-year-old woman developed bilateral leg swelling 6 years after receiving treatment for endometrial cancer. Since August 2018, she experienced > 30 episodes of lymphangitis. Upon presentation, she exhibited bilateral leg swelling and deformation, with four large swellings in the posterior thigh that impeded movement, and pain in the limbs. Skin manifestations included lichenoid lesions and features of deep sclerosis. Radionuclide lymphoscintigraphy confirmed the diagnosis of lower limb lymphedema. After 6 mo of complex decongestive therapy (CDT) and three lymphaticovenous anastomosis (LVA) treatments, the patient lost 49 kg in weight. She also experienced a maximum circumference reduction of 35.2 cm in the left lower limb and 37.5 cm in the right lower limb. The leg pain disappeared, her swelling significantly decreased, and she regained the ability to walk, cycle, and run normally. CONCLUSION: The combined application of CDT and LVA therapy demonstrates significant positive effects in the treatment of severe, deformed stage III lymphedema.
