Objective:To evaluate the efficacy of drug-coated balloons (DCB) in hemodialysis patients with peripheral artery disease (PAD) involving infrapopliteal lesions.Methods:A retrospective analysis was conducted on 53 hemodialysis patients (56 limbs, 66 lesions) with infrapopliteal PAD who underwent DCB treatment between Dec 2018 and Dec 2021. The primary outcome was improvement in Rutherford classification, while secondary outcomes included target lesion revascularization (TLR) and wound healing rate. Safety endpoints were all-cause mortality, amputation-free survival, and amputation rate.Results:The mean lesion length was (145.2±78.4) mm, and 87.5% of patients were of Rutherford grade ≥4. The median follow-up period was 14 months. Rutherford classification significantly improved at 3 and 12 months ( P< 0.001). At 12 months, TLR was 16.6%, wound healing rate was 68.6%, amputation-free survival was 73.2%, all-cause mortality was 19.8%, and amputation rate was 8.9%. Multivariate Cox regression indicated that high WIfI risk ( HR=3.936, 95% CI: 1.079-14.355, P=0.038) was an independent predictor of amputation-free survival. Conclusion:DCB is effective and safe for hemodialysis patients with infrapopliteal artery disease, while high WIfI risk predicts poor prognosis.

Objective:To investigate the effect of treatment with orchiopexy at different ages on the clinical outcomes of nonobstructive azoospermia (NOA) patients with a history of cryptorchidism who underwent microdissection testicular sperm extraction (microTESE) combined with intracytoplasmic sperm injection (ICSI).Methods:NOA patients undergoing microTESE combined with ICSI from December 2013 to August 2019 in the ICSI treatment cycle in Assisted Reproduction Center of Northwest Women and Children's Hospital were collected in this retrospective cohort study. According to the history of cryptorchidism, the patients were divided into cryptorchidism group and non-cryptorchidism group. The sperm retrieval rates (SRRs) were assessed between these two groups. Then, based on the timing of treatment with orchiopexy, the NOA patients with orchidopexy were subdivided into prepubertal group and pubertal-postpubertal group. The SRRs and the pregnancy outcomes were also assessed.Results:There were 34 NOA patients with cryptorchidism and 604 NOA patients without cryptorchidism underwent microTESE. The SRRs in NOA patients with or without cryptorchidism were 85.3% (29/34) and 40.2% (243/604), respectively. The differences were statistically significant ( P<0.001). In the prepubertal surgery group, sperm was detected in 17 cases, while in the pubertal-postpubertal surgery group, the sperm was detected in 12 cases. The differences were statistically significant ( P=0.044). The total clinical pregnancy rate of cryptorchidism NOA patients treated with ICSI was 65.4% (17/26). Among these individuals, the clinical pregnancy rate of the prepubertal group was 62.5% (10/16) and the pubertal-postpubertal group was 70.0% (7/10). There were no statistical differences in clinical pregnancy rate. Some other clinical pregnancy outcomes, including miscarriage rate in early pregnancy, the rate of cycle with 2PN and the rate of cycle with top-quality embryo, also showed no differences between the two groups. In pathology analysis, all the cryptorchidism NOA patients with failure sperm retrieval were Sertoli cell only syndrome (SCOS). The pubertal-postpubertal group had a significant higher morbidity of SCOS [76.5% (13/17)] compared with the prepubertal group [35.3% (6/17)] ( P=0.016). In addition, the volume of testis, the level of follicle-stimulating hormone and testosterone were not statistically associated with SRR. Conclusion:The SRR of NOA patients with cryptorchidism was higher than those without cryptorchidism. The age at orchidopexy operation may have little effect on the pregnancy outcome of ICSI. It may be more beneficial for microTESE to obtain sperm by undergoing orchiopexy as early as possible.

Objective To observe the effects of electro-acupuncture on loading of lower limb joints in patients with knee osteoarthritis (KOA) during stair climbing and explore the related biomechanical mechanism. Methods Forty patients with KOA were randomly assigned, with 20 patients in observation group (electro-acupuncture group, EA group) and 20 patients in control group (superficial acupuncture group, SA group). Finally 18 patients in each group completed the study. In observation group, seven knee acupuncture points were chosen and patients were connected with electro-acupuncture instrument; while in control group, the electro-acupuncture instrument was connected but not electrified after superficial acupuncture at non-acupoint points. The three-dimensional gait analysis system was used to assess the biomechanical characteristics during stair climbing before and after treatment, including peak vertical force (PFz), vertical impulse (IFz) and symmetry index (SI%). Results After 3 weeks of treatment in EA group, PFz of the right foot during stair ascent and PFz of the left foot during stair descent increased (P＜0.05); IFz of both feet during stair ascent and IFz of the right foot during stairs descent significantly decreased (P＜0.05); no significant differences were found in SI% of peak and impulse (P＞0.05). In SA group, only SI of impulse during stairs ascent increased (P＜0.05). There was no significant difference between two groups before and after treatment (P＞0.05). Conclusions Electro-acupuncture can effectively improve the joint load capacity and reduce the dynamic cumulative load of patients w

Objective To evaluate the safety and feasibility of reconstruction technique of atrial septum puncture trajectory with the help of three - dimensional mapping system in performing radiofrequency catheter ablation for atrial fibrillation. Methods Sixty- eight consecutive patients with atrial fibrillation received two times of atrial septum puncture under fluoroscopic guidance to perform radiofrequency catheter ablation. Carto 3, a three - dimensional mapping system, was employed to construct the real time left atrium and pulmonary vein anatomy by using a rapid anatomical mapping (FAM) model. Then, FAM model was used to construct the trajectory, along which the ablation catheter passed from left atrium through the long sheath to the right atrium and finally into the inferior vena cava. The safety and the feasibility of this catheter trajectory, which could allow the catheter repeatedly enter the left atrium, were evaluated. Results By using 3D-reconstruction technique of atrial septum puncture trajectory, the ablation catheter could repeatedly enter the left atrium at right anterior oblique position as well as at left anterior oblique position under zero X-ray fluoroscopy. The average time spent for the procedure was (12. 18±2. 28) seconds. No any complication occurred. Conclusion The reconstruction technique of atrial septum puncture trajectory with the help of three-dimensional mapping system is simple and feasible, the ablation catheter can repeatedly enter the left atrium, the X-ray exposure time spent for catheter ablation of atrial fibrillation can be greatly reduced.

Objective To study the therapeutic effect of combined antihuman IgG antibody with mitomycin(MMC) on human bladder cancer ceils and the primary mechanism. Methods In vitro an-tiproliferation effects of goat antihuman IgG antibody(Ab) with MMC, alone or together, on human bladder cancer cell line T24 were tested by MTT assay. Flow cytometer(FCM) was used to detect T24 cell apoptosis. Detections of activated caspase-3 and PARP[poly(ADP-ribose) polymerase] were carried out by Western blot analysis. In vivo antitumor effects of Ab of anti-human IgG with MMC were assessed using T24 xenograft in BALB/c nude mice model. Results The inhibitory rates of tumor growth of Ab, M MC and Ab+ MMC on T24 cell were (25.02±6.71)%, (32.31±6.46)% and (73.66±5.81)%, respectively. The rates of apoptotic cell of PBS, normal goat IgG, Ab, MMC, MMC±normal goat IgG, and MMC+Ab were 1.7%, 2.3%, 20.7%, 22.4%, 28.3% and 53.8%, respectively. Western blot shows Caspase-3 and PARP were cleaved in T24 cell during the course of apoptosis induced by Ab and MMC, and indicated that cell apoptosis was associated with caspase-3 and PARP activation. Under the treatment of normal goat IgG, Ab, MMC, and MMC+Ab, the in-hibitory rates of T24 xenografts in BALB/c nude mice were 2.31%, 12.73%, 36. 81%, and 50.51%, respectively. Histological examination demonstrated significant necrosis and apoptosis in the mice treated with alone MMC or Ab but no control goat IgG or PBS, in addition, HE displayed more extensive necrosis and apoptosis in the mice with MMC+Ab.Conclusion Antihuman IgG Ab with MMC has in vitro and in vivo inhibitory effects of human bladder cancer T24 , which are related to in-ducing cell apoptosis.
