Objective:To identify the key epithelial cell characteristics that can accurately diagnose eosinophilic chronic sinusitis with nasal polyps（ECRSwNP） through nasal brush sampling and comparing with the pathological results of nasal polyp tissue sections. Methods:Ninety-one patients underwent surgery in the Ophthalmology and ENT Department of the Second People's Hospital of Longgang District, Shenzhen, from January 2022 to July 2024 were selected. The cohort comprised 58 males and 33 females（mean age: 41.4 years; range: 12.0-71.0）. The clinical characteristics of the patients, including gender, age, disease duration, smoking and drinking history, asthma history, subjective symptoms, sinus CT, and nasal endoscopy scores, were recorded. Nasal brush sampling of nasal polyps and inferior turbinate mucosa was performed before surgery to obtain cytological specimens, and nasal polyp tissues were collected during surgery. The demographic and clinical characteristics of patients with eosinophilic and non-eosinophilic nasal polyps were compared, as well as the relationship between nasal brush cytology of nasal polyps and inferior turbinate and nasal polyp histopathology. Statistical analysis was performed using SPSS 23.0 software. Results:Among the 91 patients, no significant differences were observed between ECRSwNP and NECRSwNP patients in terms of age, gender, smoking status, alcohol consumption, and disease duration. The nasal brush cell population in ECRSwNP patients was more likely to contain eosinophils（P<0.001） and less likely to contain lymphocytes and plasma cells（P<0.001）. Additionally, the ciliated cells in ECRSwNP patients exhibited larger widths（P=0.036）, shorter cilium lengths（P<0.001）, and more disordered arrangements（P<0.001） compared to NECRSwNP patients. In nasal brush cells from the inferior turbinate, ECRSwNP patients also showed shorter cilium lengths（P<0.001） and shorter cilia（P=0.024） compared to NECRSwNP patients. Conclusion:There are significant differences in obtaining epithelial cytological information from nasal polyps or inferior turbinates through nasal brush sampling between ECRSwNP and NECRSwNP patients.

OBJECTIVES: This study aimed to explore the clinical efficacy of severe early childhood caries (SECC) treatment combined with local anesthesia under general anesthesia. METHODS: A total of 108 children under 6 years old who underwent SECC dental treatment under general anesthesia at the Department of Pediatric Dentistry, Third Affiliated Hospital of Air Force Medical University from March to December 2023 were selected as the study subjects, with American Society of Anesthesiologists (ASA) classification of classⅠor Ⅱ. The study subjects were divided into a control group (n=54) and an experimental group (n=54) by retrieving intraoperative cases and postoperative follow-up records. The control group was given general anesthesia through inhalation combined with nasotracheal intubation, whereas the experimental group was given local anesthesia with 2% lidocaine on each treated tooth on the basis of general anesthesia. The basic information, preoperative anesthesia depth, hemodynamic changes during different surgical procedures, postoperative pain, and adverse reactions in the two groups were recorded and analyzed. RESULTS: No statistically significant difference was found in the basic information and preoperative anesthesia depth between the two groups (P>0.05). Among the three procedures (pulpotomy, root canal treatment, and tooth extraction), the three observed indicators in the experimental group were significantly lower than those in the control group (P<0.05). The proportion of patients in the experimental group who needed to take analgesic measures in accordance with the modified facial pain scale (FPS-R) score was significantly lower than that in the control group at postoperative wakefulness and 2 h after surgery (P<0.05). Meanwhile, no statistically significant difference was observed between the groups at 24 h after surgery (P>0.05). The proportion of patients in the experimental group who needed to take analgesic measures on the basis of the parent posto-perative pain measurement (PPPM) score was significantly lower than that in the control group when they were awake after surgery (P<0.05). No statistically significant difference was found between the groups at 2 and 24 h after surgery (P>0.05). Moreover, no statistically significant difference was observed in the incidence of adverse reactions between the two groups at 24 h after surgery (P>0.05). CONCLUSIONS The combination of local anesthesia during SECC dental treatment under general anesthesia results in minimal changes in intraoperative hemodynamics and mild postoperative pain response, hence worthy of clinical promotion.

Objective To investigate the clinical effect of Mudan Granules combined with pentoxifylline in the treatment of type 2 diabetes mellitus (T2DM) with early renal disease and analyze its impact on the Toll-like receptor 4 (TLR4)/nuclear factor-κB (NF-κB) signaling pathway. Methods A total of 164 patients with T2DM and early renal disease admitted to the Second People's Hospital of Hunan Province between May 2022 and October 2023 were enrolled and randomly divided into observation group(n=82) and control group (n=82) using a random number table in a 1-to-1 ratio. The control group received pentoxifylline treatment, while the observation group received Mudan granules combined with pentoxifylline. The clinical effects and changes in renal function indicators[serum creatinine (SCr), urea nitrogen, urinary albumin-to-creatinine ratio (UACR)], TLR4/NF-κB signaling pathway indicators (TLR4, MyD88, NF-κB mRNA), and inflammation and oxidative stress indicators [C-reactive protein (CRP), glutathione peroxidase (GSH-PX), malondialdehyde (MDA), total antioxidant capacity (TAC), and transforming growth factor β1 (TGF-β1)] before and after treatment were compared between the two groups. Results The total effective rate in the observation group was 97.56%, which was higher than 89.02% in the control group (P<0.05). At 6 and 12 weeks after treatment, the levels of SCr, urea nitrogen, and UACR in both groups decreased compared with those before treatment, and the levels of these indicators in the observation group were lower than those in the control group (P<0.05). At 6 and 12 weeks after treatment, the levels of TLR4, MyD88, and NF-κB mRNA in both groups decreased compared with those before treatment, and the levels of these indicators in the observation group were lower than those in the control group (P<0.05). At 6 and 12 weeks after treatment, the levels of GSH-PX and TAC in both groups increased, while the levels of CRP, MDA, and TGF-β1 decreased compared with those before treatment. The levels of GSH-PX and TAC in the observation group were higher than those in the control group, while the levels of CRP and MDA were lower (P<0.05). Conclusion Mudan Granules combined with pentoxifylline in the treatment of T2DM with early renal disease can improve renal function to a certain extent, regulate the TLR4/NF-κB signaling pathway, and reduce inflammation and oxidative stress responses, which is beneficial for disease control.

[Objective] To summarize the diagnosis and treatment of Antopol Goldman lesion (AGL) in clinical practice. [Methods] Clinical data and diagnosis and treatment process of one AGL case treated in our hospital were retrospectively analyzed, and relevant literature was reviewed. [Results] The patient presented with painless gross hematuria and right-sided lower back pain.Imaging examination suggested swelling of the right kidney, blood accumulation in the right calyx, renal pelvis and lower ureter, blood clot in the bladder, and multiple small stones in the left kidney.After multidisciplinary consultation, close imaging follow-up, interventional and flexible ureterdscope examination, tumors of hematological diseases, renal hematuria, arteriovenous fistula and collection system were excluded.After conservative treatment, the patient gradually recovered.During the follow-up of 1 year, no hematuria or low back pain recurred. [Conclusion] There is no clear diagnostic standard for AGL.Diagnosis relies on imaging, interventional methods and ureteroscopy.It is necessary to exclude other diseases and adopt conservative treatment.

Complicated crown root fracture is a serious combined fracture of the enamel,dentin,and cementum in dental trauma.The treatment method is complicated.During the procedure,the condition of pulp,periodontal,and tooth body should be thoroughly evaluated,and a multidisciplinary approach combined with sequential treatment is recom-mended.This case reported the different treatment and repair processes of one case of two affected teeth after complicat-ed crown root fracture of upper anterior teeth,including regrafting of broken crown after flap surgery at the first visit,di-rect resin repair to remove broken fragments,and pulp treatment and post-crown repair at the second visit.After 18 months of follow-up,the preservation treatment of the affected teeth with complicated crown root fracture was achieved.Therefore,fragment reattachment and post-crown restoration are feasible treatment options for children with complicated crown root fracture.

Objective:To investigate the strategies and clinical effects of free tissue flaps in repairing massive destructive burn wounds.Methods:This study was a retrospective observational study. From June 2014 to October 2023, 51 burn patients with 53 massive destructive burn wounds which met the inclusion criteria were admitted to Tongren Hospital of Wuhan University & Wuhan Third Hospital, including 47 males and 4 females, aged 21 to 77 years. After debridement, the wound area needed to be repaired by tissue flaps ranged from 20.0 cm×12.5 cm to 50.0 cm×15.0 cm. Emergency, early, or delayed transplantation of tissue flaps was performed to repair the wounds. Six head, face, and neck wounds, 5 upper limb wounds, and 1 lower limb wound were repaired with latissimus dorsi myocutaneous flaps. Eleven upper limb wounds and 6 lower limb wounds were repaired with anterolateral thigh flaps. Seven upper limb wounds, 5 lower limb wounds, and 2 face and neck wounds were repaired with paraumbilical perforator flaps. One lower limb wound was repaired with lower abdominal flap. Two face and neck wounds, 2 upper limb wounds, and 1 lower limb wound were repaired with inguinal flaps. One upper limb wound was repaired with scapular flap. One trunk wound was repaired with the "fillet flap" from the abandoned upper limb after amputation. Three head, face, and neck wounds, 3 lower limb wounds, and 1 upper limb wound were repaired with omental flaps. Four wounds were repaired by combined transplantation of the above-mentioned tissue flaps. Three wounds were repaired by fractional transplantation of the above-mentioned tissue flaps. The size of a single harvested tissue flap ranged from 15.0 cm×5.0 cm to 45.0 cm×25.0 cm. The arterial and venous anastomoses were added as the circumstances might require to improve tissue flap circulation. The wounds in the flap donor sites were sutured directly or repaired by split-thickness skin grafts from head. The general condition of patients during treatment was recorded. After surgery, the survival of tissue flaps, the healing of wounds in the recipient sites, limb salvage, the healing of wounds in the flap donor sites, and the survival of skin grafts were observed. The healing of wounds in the recipient sites was observed during follow-up. At the last follow-up, the upper limb function after successful limb salvage was evaluated by the Arm, Shoulder, and Hand Disability Scoring Scale, the weight-bearing walking ability of patients with successful lower limb salvage was evaluated by the Holden walking ability classification, and the patient's satisfaction with the efficacy was assessed by 5-grade Likert scale.Results:During treatment, one case with electrical burn of the head suffered from aggravated cerebral edema, cerebral hernia and coma recurred. After dehydration, hormone therapy, and so on, the patient recovered and incomplete hemiplegia on the right limb was left. The shock symptoms of 4 patients got worse, which were gradually controlled after anti-shock with fluid supplement and colloid injection. One patient developed hemorrhagic shock after tissue flap transplantation, which was corrected by fluid infusion and red blood cell suspension transfusion. Vascular crisis occurred in 3 tissue flaps after surgery, of which 2 survived and 1 eventually became necrotic after exploration. Partial necrosis occurred in 2 tissue flaps and slight necrosis occurred at the edge of 5 tissue flaps, which all healed after tissue flap trimming, vacuum sealing drainage (VSD), and skin grafting treatment. All the other tissue flaps survived. There were 12 recipient wounds with residual necrotic tissue after surgery, which healed after debridement, VSD, and skin grafting treatment. The remaining 41 wounds healed well. Among the 40 limb wounds of 39 patients, 5 patients had 3 upper limb and 2 lower limb amputations. The remaining 35 limbs of 34 patients were successfully salvaged. The donor site wounds healed well, and the skin grafts survived well. During the follow-up of 6 to 52 months, all the head, face, neck, and trunk wounds were well repaired. The fester recurred in 7 limb wounds 3 to 9 months after surgery and healed after debridement, drainage, and tissue flap repair. At the last follow-up, the functional scores of 22 upper limbs after successful limb salvage ranged from 0 to 100 (with an average of 50), and the Holden walking ability classification of 12 patients with 13 lower limbs after successful limb salvage was level Ⅴ in 8 cases, level Ⅳ in 2 cases, and level Ⅲ in 2 cases. The patients were very satisfied with the efficacy in 33 cases, relatively satisfied in 12 cases, and not quite satisfied in 6 cases.Conclusions:Systematic evaluation and treatment of the whole body condition, choosing the appropriate repair time, and using appropriate tissue flaps to repair massive destructive burn wounds will help ensure the safety of treatment, improve the repair effect, and reduce the injury of donor sites, thus optimizing the repair effect.

Objective:To investigate the application value of transanal intersphincteric resec-tion under direct vision in the Jackknife position in the anal preserving surgery for ultra-low rectal cancer.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 15 patients with ultra-low rectal cancer who underwent transanal intersphincteric resection under direct vision in the Jackknife position, combined with laparoscopic total mesorectal excision in Huizhou Municipal Central Hospital from September 2021 to November 2022 were collected. There were 9 males and 6 females, aged (63±9)years. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers. Results:(1) Surgical and postoperative outcomes. All the 15 patients underwent operations successfully, without conversion to open abdo-minal operation. There were 5 cases of partial ISR and 10 cases of subtotal ISR. The operation time and volume of intraoperative blood loss of 15 patients were (260±30)minutes and 20(range, 10-30)mL, respectively. The distance from anastomosis to anal margin was (1.6±0.8)cm. The duration of post-operative hospital stay was 10(range, 8-13)days, and all 15 patients underwent colonic and anasto-mosis with staplers and protective ileostomy at the terminal ileum. Three patients had postoperative complications within 30 days after surgery, of whom 1 case with grade A anastomotic leakage was cured after conservative treatment and 2 cases with anastomotic membranous stenosis were cured by anal enlargement. (2) Postoperative pathological examination. The number of lymph nodes dissected of 15 patients was 18 ±6, and the distance between the tumor and distal resection margin was 1.3(range, 1.0-2.0)cm. The surgical specimens of all 15 patients showed complete mesorectum and negative for proximal, distal and circumferential margins. Results of postoperative pathological examination showed that there was 1 case in stage pT1N0M0, 9 cases in stage pT2N0M0, 1 case in stage pT2N1M0, 1 case in stage ypT0N0M0, 2 cases in stage ypT2N0M0, 1 case in ypT3N1M0 stage. The histological subtype showed 11 cases of moderately differentiated adenocarcinoma and 4 cases of well-differentiated adenocarcinoma. (3) Follow-up. All 15 patients were followed up for 15(range, 12-24)months. No local recurrence and distant metastasis of the tumor was found, and no tumor-related death occurred. All 15 patients underwent stoma closure. The postoperative anal function assessment of 15 patients showed no disorder in 5 cases, mild disorder in 8 cases and severe disorder in 2 cases.Conclusion:Transanal intersphincteric resection under direct vision in the Jackknife position in the anal preserving surgery for ultra-low rectal cancer is safe and feasible.

Objectives:To explore the clinical use and observe the clinical efficacy of the Pivox system in oblique lateral interbody fusion(OLIF)in treating single-segment lumbar spinal diseases.Methods:The clini-cal data of patients with single-segment lumbar spinal diseases(Discogenic low back pain,lumbar spondylolis-thesis,lumbar spinal stenosis)who underwent OLIF without posterior instrumentation from May 2020 to Jan-uary 2021 in our hospital were collected,including 36 males and 33 females,aged 32-79 years old(59.1±5.9 years).And the patients were divided into OLIF stand-alone group(39 patients)and Pivox+OLIF group(30 pa-tients).The perioperative parameters of the two groups of patients were compared,including incision length,operative time,intraoperative blood loss,and length of hospital stay.The visual analogue scale(VAS)and Os-westry disability index(ODI)were assessed before operation,at 1 week,1,3,6 and 12 months after operation for clinical efficacy.The intervertebral disc height,foraminal height and foraminal area before and after oper-ation,and the fusion rate were evaluated and compared between the two groups.Complications were recorded and compared as well.Results:The patients were followed up for 14.0±0.3 months(12-18 months).No signif-icant differences were found between the two groups in gender,age,disease type,operative level,bone min-eral density(BMD),or body mass index(BMI)(P＞0.05).The operative time in OLIF group was shorter than that in Pivox+OLIF group(P＜0.05),while there were no significant differences in blood loss,incision length and hospital stay(P＞0.05).The VAS score and ODI index in both groups before surgery were higher than those at 1 week,1 month,3 months,6 months,and 12 months after surgery(P＜0.05).No significant differences in VAS and ODI were found at 1 week,1 month,3 months,6 months,and 12 months after surgery between the two groups,respectively(P＞0.05).The intervertebral disc height,foraminal height and foraminal area at postoperative 1 week,6 and 12 months were all greater than those before operation in both groups,while the increase values of intervertebral disc height,foraminal height and foraminal area in Pivox+OLIF group were greater than those in OLIF group at 1 week,and 6 and 12 months after surgery,but without statistical differ-ences(P＞0.05).Cage subsidence occurred in both groups,and cage displacement was noticed in two cases in the OLIF group,while none was there in the Pivox+OLIF group.There were no significant differences in fu-sion rate and incidence of complications between two groups(P＞0.05).Conclusions:The short-term effect of Pivox+OLIF procedure in the treatment of single-segment lumbar degenerative diseases is satisfactory,but comparing with stand-alone OLIF,Pivox+OLIF has no obvious advantage in spinal canal decompression and preventing cage subsidence.

Objectives:To investigate the effectiveness and safety of unilateral approach contralateral under-cutting decompression assisted with ultrasonic osteotome in treating severe degenerative lumbar spinal stenosis.Methods:174 patients with severe degenerative lumbar spinal stenosis who were treated with ultrasonic os-teotome assisted unilateral approach contralateral undercutting decompression between June 2018 and June 2021 were collected[unilateral approach bilateral decompression transforaminal lumbar interbody fusion(TLID group,group A],and 129 patients undergone bilateral transforaminal decompression during the same period were randomly selected as control(bilateral small incision TLIF group,group B).The perioperative parameters such as incision length,operative time,intraoperative blood loss,postoperative drainage,and length of hospital stay were recorded and compared between the two groups.Creatine phosphokinase(CPK)test was performed to evaluate muscle damage conditions,and visual analogue scale(VAS)and Oswestry disability index(ODI)were used to evaluate the postoperative therapeutic effects.The complications and fusion conditions were compared between the two groups.Results:There wasn't significant difference in average length of bilateral incisions and length of hospital stays between the two groups(P＞0.05).Group A was less significantly than group B in terms of operative time,intraoperative blood loss,and postoperative drainage,with statistical significance(P＜0.05).The preoperative CPK value was comparable between the two groups(P＞0.05),and on postoperative 1d and 3d it was statistically greater in group B than in group A(P＜0.05),but on postoperative 5d it wasn't sig-nificantly different between the two groups(P＞0.05).The postoperative VAS scores and ODI improved com-pared with the preoperative values in both groups on postoperative 3d,at 1 month,3 months,and 12 months(P＜0.05),and there was no statistical difference between the two groups respectively at the same follow-up period(P＞0.05),even though group A was better in ODI and VAS than group B at 12 months after operation.There was no significant difference between the two groups in postoperative complications such as dural tear,incision fat liquefaction,cerebrospinal fluid leakage and postoperative infection.Group A was less in the pro-portion of postoperative worsening lower limb numbness and rebound of hip/lower limb symptoms than in group B(P＜0.05).1 year after operation,12 cases in group A were not fused,and 8 cases in group B were not fused.There was no statistically significant difference in the bone graft fusion between the two groups(P＞0.05).Conclusions:Comparing with bilateral small incision TLIF,ultrasonic osteotome assisted unilateral ap-proach contralateral undercutting decompression also can achieve good treatment results,which features in less trauma,less effects on spinal stability,shorter operative time,and less intraoperative blood loss,and therefore worth in clinical promotion.
