OBJECTIVE: To compare the effects of double-channel core decompression (CD) combined with medullary cavity irrigation with those of simple CD on progression of collapse and clinical outcomes in non-traumatic osteonecrosis of the femoral head (ONFH). METHODS: A retrospective analysis was conducted on the clinical data of 19 patients (30 hips) with non-traumatic ONFH who underwent double-channel CD combined with medullary cavity irrigation and admitted between January 2024 and October 2024 (CD+irrigation group). According to a 1: 2 ratio, 54 patients (60 hips) who underwent simple CD and were matched in terms of age, gender, and body mass index (BMI) were included as the control (CD group). There was no significant difference in baseline data such as age, gender, BMI, affected side, ONFH type, preoperative Association Research Circulation Osseous (ARCO) stage, bone marrow edema stage, visual analogue scale (VAS) score for pain, and Harris score between the two groups ( P>0.05). The postoperative discharge time and occurrence of complications were recorded for both groups. The VAS scores before operation and at discharge after operation were compared, and the differences between pre- and post-operation (change values) were calculated for intergroup comparison. The Harris scores before operation and at discharge and 3 months after operation were also compared. During follow-up, X-ray film, CT, and MRI were performed for reexamination. The ARCO stage and bone marrow edema stage were evaluated at 3 months after operation and compared with those before operation to determine whether there was radiological progression or relief. RESULTS: All incisions in both groups healed by first intention after operation, with no infection, femoral neck fracture, or other operation-related complications. All patients were followed up, and the follow-up time of the CD+irrigation group was (146.8±27.7) days, and that of the CD group was (164.3±48.2) days; there was no significant difference between the two groups ( t=1.840, P=0.069). There was no significant difference in the length of hospital stay between the two groups ( P>0.05). At discharge after operation, the VAS score of the CD+irrigation group was significantly lower than that of the CD group ( P<0.05), and the change value was significantly higher than that of the CD group ( P<0.05). The Harris scores at discharge and 3 months after operation in the CD+irrigation group were significantly higher than those in the CD group ( P<0.05). The Harris score gradually increased with time, and the differences between different time points were significant ( P<0.05). Radiological reexamination showed that there was no significant difference in the ARCO stage and the incidence of radiological progression between the two groups at 3 months after operation ( P>0.05); however, the bone marrow edema stage and the degree of bone marrow edema relief in the CD+irrigation group were better than those in the CD group, with significant differences ( P<0.05). CONCLUSION Double-channel CD combined with medullary cavity irrigation can significantly alleviate hip joint pain and improve joint function in patients with non-traumatic ONFH, reduce the degree of bone marrow edema in the femoral head, and delay the progression of ONFH.

OBJECTIVE: To explore the clinical effects of sterilization of vas deferens by irrigation in clinic. METHODS: Eighty-six male patients with voluntary sterilization were divided into control group (usual vasectomy, n=50) and observation group (sterilization of vas deferens by irrigation, n=36). The age, testicular volume, preoperative average concentration of spern, serum testosterone level, recovery duration evaluated by Artificial Obstruction Azoospermia (AOA) and degree of satisfaction were compared between the two groups of patients. RESULTS: There were significant differences in recovery duration, degree of satisfaction between the two groups (P<0.05). And there was no significant difference in age （［32.0±5.5］years vs ［31.0±6.3］years）, testicular volume （［16.0±4.8］mL vs ［17.0±4.4］mL）, preoperative average concentration of sperm (［39.6±20.2］ ×106/mL vs ［40.2±22.6］ ×106/mL) and levels of blood testosterone （［4.3±0.8］ng/mL vs ［4.4±0.8］ ng/mL）. There was significant difference in patency rate between the two sides of testicular ducts（91.7% vs 83.3%, P<0.05）. CONCLUSION The method of sterilization of vas deferens by irrigation is worth popularizing in clinic.

OBJECTIVES: This study aimed to compare the effectiveness of ultrasound and acoustic and laser cleaning of curved root canals. METHODS: A total of 92 molars with independent root canals with a curvature of 20°-40° were prepared and standardized at 04 25# and stained with gentian violet solution for 72 h. Among them, 52 were randomly divi-ded into four groups for final rinsing (n=13): NI group, PUI group, EDDY group, and PIPS group. Ten samples in each group were cut horizontally along the long axis perpendicular to the root and divided into curved upper, curved, and apical segments. Images were taken with a stereomicroscope and Image J measurements were taken to calculate the depth of rinse penetration. The remaining three samples from each group were split along the long axis of the dentin, photographed by scanning electron microscope to record the dentin tubule exposure and staining layer, and scored for staining layer by double-blind method. SPSS 26.0 software was used to perform statistical analysis and select the best flushing method. An extra 40 samples were randomly divided into four groups for detection of flushing fluid penetration depth (n=10): 10, 20, 30, and 40 s. RESULTS: In the upper part, the mean depth of infiltration was not significantly different between the experimental and control groups (P>0.05). The PIPS group had a significantly lower smear layer score than the control group and the EDDY group (P<0.01). In the curved segment, the mean depth of infiltration was significantly greater in the PUI group than in the control group (P<0.05); the tarnish layer score was lower in each experimental group than in the control group. At the top, the mean depth of infiltration was greater in the PUI and PIPS groups than in the control group (P<0.05), and the smear layer score was lower in the PIPS group than in the other groups (P<0.05). After the time was changed, the depth of infiltration of PUI increased only in the apical segment as the flushing time increased. CONCLUSIONS The PUI and PIPS methods facilitate the penetration of irrigation solution into the dentin canal in curved root canals, especially in the apical segment. The PIPS technique is effective in removing the smear layer in curved root canals.

Lateral epicondylopathy represents pain in the lateral (radial aspect) of the elbow caused by degeneration in the common extensor tendon. Calcium deposit frequently developes in lateral epicondylopathy, with the prevalence up to 46%. There are considerable debates on its treatment protocols for lateral epicondylopathy so far, likewise, the effective treatment method for calcific lateral epicondylopathy has not been established. We report here a case of chronic intractable calcific lateral epicondylopathy treated with ultrasound-guided barbotage and focused type extracorporeal shock wave therapy (ESWT). To our knowledge, this is the first report of calcific lateral epicondylopathy treated by ultrasound-guided barbotage combined with ESWT.

ObjectiveTo evaluate the effectiveness and safety of low-concentration hydrogen peroxide solution (HPS) for continuous bladder irrigation after transurethral resection of the prostate (TURP).

METHODSWe retrospectively analyzed the clinical data about 148 cases of benign prostatic hyperplasia (BPH) treated by TURP from January 2013 to January 2016. Seventy-six of the patients received postoperative continuous bladder irrigation with 0.15% HPS (group A) and the other 72 with normal saline (group B). We compared the two groups of patients in their postoperative hemoglobin (Hb) levels, duration of bladder irrigation, frequency of catheter blockage, time of catheterization, and length of hospital stay.

RESULTSThere were no statistically significant differences between the two groups of patients preoperatively in the prostate volume, International Prostate Symptoms Score, maximum urinary flow rate, postvoid residual urine, or levels of serum PSA and Hb (P > 0.05). At 48 hours after operation, a significantly less reduction was observed in the Hb level in group A than in group B (［3.38 ± 2.56］ vs ［7.29 ± 6.58］ g/L, P < 0.01). The patients of group A, in comparison with those of group B, also showed remarkably shorter duration of postoperative bladder irrigation (［32.57 ± 5.99］ vs ［46.10 ± 8.79］ h, P < 0.01), lower rate of catheter blockage (3.3% vs 11.8%, P < 0.01), shorter time of catheterization (［3.74 ± 0.79］ vs ［4.79 ± 0.93］ d, P < 0.01), and fewer days of postoperative hospital stay (［4.22 ± 0.81］ vs ［4.67 ± 0.88］ d, P < 0.01).

CONCLUSIONSLow-concentration HPS for continuous bladder irrigation after TURP can reduce blood loss, catheter blockage, bladder irrigation duration, catheterization time, and hospital stay, and therefore deserves a wide clinical application.

The principles of open fracture management are to manage the overall injury and specifically prevent primary contamination becoming frank infection. The surgical management of these complex injuries includes debridement & lavage of the open wound with combined bony and soft tissue reconstruction. Good results depend on early high quality definitive surgery usually with early stable internal fixation and associated soft tissue repair. While all elements of the surgical principles are very important and depend on each other for overall success the most critical element appears to be achieving very early healthy soft tissue cover. As the injuries become more complex this involves progressively more complex soft tissue reconstruction and may even requiring urgent free tissue transfer requiring close co-operative care between orthopaedic and plastic surgeons. Data suggests that the best results are obtained when the whole surgical reconstruction is completed within 48-72 h.

Objective: To compare the clinical effect of diode laser enucleation of the prostate (DIOD) with that of transurethral resection of the prostate (TURP) on benign prostate hyperplasia (BPH) with different prostate volumes. METHODS: This retrospective study included 256 BPH patients treated by DIOD (n = 141) or TURP (n = 115) from March 2012 to August 2015. According to the prostate volume, we divided the patients into three groups: <60 ml (42 for DIOD and 31 for TURP), 60－80 ml (51 for DIOD and 45 for TURP), and >80 ml (48 for DIOD and 39 for TURP). We obtained the relevant data from the patients before, during and at 6 months after surgery, and compared the two surgical strategies in operation time, perioperative levels of hemoglobin and sodium ion, post-operative urethral catheterization time and bladder irrigation time, pre- and post-operative serum PSA levels, International Prostate Symptoms Score (IPSS), post-void residual urine (PVR) volume and maximum urinary flow rate (Qmax), and incidence of post-operative complications among different groups. RESULTS: In the <60 ml group, there were no remarkable differences in the peri- and post-operative parameters between the two surgical strategies. In the 60－80 ml group, DIOD exhibited a significant superiority over TURP in the perioperative levels of hemoglobin (［3.25 ± 1.53］ g/L vs ［4.77 ± 1.67］ g/L, P <0.05) and Na+ (［3.58 ± 1.27］mmol/L vs ［9.67 ± 2.67］ mmol/L, P <0.01), bladder irrigation time (［30.06 ± 6.22］h vs ［58.32 ± 10.25］ h, P <0.01), and urethral catheterization time (［47.61 ± 13.55］ h vs ［68.01 ± 9.69］ h, P <0.01), but a more significant decline than the latter in the postoperative PSA level (［2.34 ± 1.29］ ng/ml vs ［1.09 ± 0.72］ ng/ml, P <0.05), and similar decline was also seen in the >80 ml group (［3.35 ± 1.39］ ng/ml vs ［1.76 ± 0.91］ ng/ml, P <0.05). No blood transfusion was necessitated and nor postoperative transurethral resection syndrome or urethral stricture observed in DIOD. However, the incidence rate of postoperative pseudo-urinary incontinence was significantly higher in the DIOD (22.7%, 32/141) than in the TURP group (7.83%, 9/115) (P <0.05). CONCLUSIONS DIOD, with its obvious advantages of less blood loss, higher safety, faster recovery, and more definite short-term effectiveness, is better than TURP in the treatment of BPH with medium or large prostate volume and similar to the latter with small prostate volume.

OBJECTIVETo investigate the effect of closed vacuum drainage combined with heparin irrigation in the treatment of scald burns with seawater immersion in rabbits.

METHODSTwenty New Zealand rabbits were subjected to deep partial-thickness scald burns in 4 regions on the bilateral skin of the spine. The wounds were managed with common dressing (group A), common dressing after seawater immersion (group B), closed vacuum drainage after seawater immersion (group C), or closed vacuum drainage combined with heparin irrigation after seawater immersion (group D). Wound effusion and tissue necrosis were observed at 1, 3, 5 and 7 days after the burns. Tissue samples were collected from the wounds for HE staining and immunohistochemistry for VEGF and CD31, and the changes of capillary endothelial cells in the wound were observed using electron microscopy. The water content in the wound tissues was determined, and the wound healing rate was calculated after the injury.

RESULTSSea water immersion of the wound results in earlier onset of edema and more extensive tissue necrosis in the scalded rabbits. The mean necrotic area in groups C and D was smaller than that in group B early after the burns, and vacuum drainage promoted necrotic tissue elimination and accelerated wound healing. Early after the burns, water content in the tissues increased with time in all the groups and reached the highest level at 3 days, and was significantly lower in groups C and D than in group B. Pathologically, vascular endothelial cell damage at the wound site was worsened after seawater immersion. In group D, the basement membrane damage was milder and the endothelial cell membrane remained intact at the wound site, where new blood vessels occurred at 3 days after the burns, a time earlier than that in the other 3 groups with also the highest vascular density.

CONCLUSIONSClosed vacuum drainage combined with heparin irrigation can relieve edema at the scald wound with seawater immersion, improve microcirculation, accelerate the removal of necrotic tissue, and promote the growth of new blood vessels.

OBJECTIVETo evaluate the safety and effectiveness of a modified method of holmium laser enucleation of the prostate (HoLEP)--6-o'clock tunnel HoLEP for the treatment of benign prostate hyperplasia (BPH).

METHODSWe included 112 cases of BPH in this study, 57 treated by 6-o'clock tunnel HoLEP (experimental group) and the other 55 by conventional HoLEP (control group). We compared the operation time, volume of the resected prostatic tissue, intraoperative blood transfusion, volume of bladder irrigation solution, postoperative hemoglobin change, and incidence of urinary incontinence between the two groups.

RESULTSStatistically significant differences were observed between the experimental and control groups in the operation time ([56.01 ± 8.62] min vs [68.65 ± 9.08] min), cases of intraoperative blood transfusion (0 vs 2), volume of bladder irrigation solution ([27.51 ± 3.67] L vs [36.89 ± 6.47] L), postoperative hemoglobin decrease ([10.70 ± 2.50] g/L vs [12.60 ± 3.30] g/L), and cases of postoperative stress-induced urinary incontinence (2 vs 7) (all P <0.05). One-month follow-up revealed smooth urination in both groups of patients but no true urinary incontinence or secondary bleeding in either.

CONCLUSIONModified 6-o'clock tunnel HoLEP can significantly reduce the operation time, bladder irrigation, and intraoperative bleeding, and therefore can be used as a safe and effective option for the treatment of BPH.
