A case of maxillary sinus cyst removal via lateral wall fenestration combined with sinus floor elevation and implant placement was reported.A 52-year-old female presented with bilateral posterior maxillary tooth loss.Preoperative CBCT revealed two dome-shaped pseudocysts at the right maxillary sinus floor,with intact sinus walls.During surgery,lateral wall fenestration was performed,followed by cyst aspiration and removal.The sinus mucosa was repaired using an absorbable collagen barrier membrane(Bio-Gide?),and deprotein-ized bovine bone matrix(Bio-Oss?)was implanted for bone augmentation.Postoperative CBCT at 9 months showed ideal bone height and density at the sinus floor,with no cyst recurrence and successful osseointegration of implants.The results suggest that concurrent cyst re-moval during sinus floor elevation could achieve stable bone augmentation when large cysts compromise the procedure.

AIM: To investigate the relationship between Apelin and δ-like ligand 4(DLL4)expression levels and clinical stage and efficacy in patients with neovascular glaucoma(NVG).METHODS: A total of 96 NVG patients(96 eyes)who were admitted to our hospital from January 2022 to March 2024(NVG group)and 96 cataract patients(96 eyes)who underwent cataract surgery in our hospital during the same period(control group)were selected. NVG patients were divided into stage Ⅰ group(22 eyes), stage Ⅱ group(47 eyes)and stage Ⅲ group(27 eyes)according to the clinical stage; furthermore, patients were divided into ineffective group(20 eyes)and effective group(76 eyes)according to efficacy. Aqueous humor Apelin and DLL4 levels were detected by enzyme-linked immunosorbent assay. The influencing factors of the efficacy in NVG patients were analyzed by multivariate unconditional Logistic regression analysis, the evaluation efficiency of aqueous humor Apelin and DLL4 levels on the efficacy in NVG patients was analyzed by receiver operating characteristic(ROC)curve.RESULTS: Compared with the control group, aqueous humor Apelin and DLL4 levels in the NVG group were increased(all P<0.001). Aqueous humor Apelin and DLL4 levels in the stage Ⅰ, stage Ⅱ and stage Ⅲ groups increased in turn(all P<0.001). The effective rate of 96 NVG patients was 79.2%(76/96). Compared with the effective group, aqueous humor Apelin and DLL4 levels in the ineffective group increased(all P<0.001). Clinical stage III, high intraocular pressure, high Apelin and DLL4 were independent risk factors for ineffective treatment in NVG patients(all P<0.05). The area under the curve of the combined evaluation of aqueous humor Apelin and DLL4 levels in evaluating the efficacy of NVG patients was 0.874, which was greater than 0.790 and 0.786 of aqueous Apelin and DLL4 levels alone(all P<0.05).CONCLUSION: Aqueous humor Apelin and DLL4 levels in NVG patients increase, which relate to the increase of clinical stage and poor efficacy, and the combination of aqueous humor Apelin and DLL4 levels is more effective in evaluating the efficacy of NVG patients.

Objective To evaluate the impact of optimizing the stroke green channel on the efficiency of acute ischemic stroke management in a county hospital. Methods A retrospective analysis of the emergency stroke green channel treatment data from Sixian People’s Hospital from May 2020 to April 2021 (before optimization of the green channel) and from May 2021 to April 2022 (after optimization of the green channel) was conducted. The rates of intravenous thrombolysis (IVT) and mechanical thrombectomy (MT) patients, as well as door-to-needle time (DNT), door-to-puncture time (DPT), and the modified Rankin scale (mRS) scores of patients three months post-treatment before and after the optimization of the stroke green channel were compared. Results Within one year before and after optimization of the green channel, the number of acute visits for ischemic stroke was 3 143 and 2 623, respectively. Before optimization, 84 and 51 underwent IVT and MT, respectively. After optimization of the green channel, the ratios of patients underwent IVT (n=215) and MT (n=103) significantly increased, and both DNT and DPT were significantly shortened (P<0.000 1); the proportion of MT patients with an mRS score of 0-2 at 3 months post-discharge significantly increased (46/99 vs 13/46, P=0.038). Conclusion After optimizing the green channel at Sixian People’s Hospital, the efficiency of stroke treatment has significantly improved, and the patients’ prognosis improved.

Dysphagia is the main complication of chemoradiotherapy for head and neck cancer. Recently, the advancement of multidisciplinary treatment has achieved a higher tumor control rate, but also a higher incidence of late radiation-induced dysphagia in head and neck cancer. Radiation-induced dysphagia leads to prolonged unnatural feeding, nutritional deficiency, weight loss, and also has a major risk for silent aspiration and aspiration pneumonia, which significantly reduces the quality of life of patients. Besides, late radiation-induced dysphagia is the main reason for limiting the intensity of treatment. Therefore, it is of great significance to deeply understand the pathogenesis of radiation-induced dysphagia and actively explore effective prevention and treatment measures to improve the survival rate and quality of life in head and neck cancer. This paper summarizes the pathogenesis, occurrence, risk factors of radiation-induced dysphagia in head and neck cancer, as well as the progress in the measurement and reporting methods, prevention and treatment strategies.

Objective:To investigate the changes in the morphology, structure and function of the bladders and their effects on the upper urinary tract dilatation(UUTD) after lumbosacral nerve transecting in rats.Methods:A total of 45 female SD rats were included, randomly divided into 3 groups with 15 rats in each group. Two groups were performed bilateral lumbar 6(L6) and cauda equina nerve shearing to establish neurogenic bladder(NB) model, which were nerve transected for 4 weeks(NB-4W) group and nerve transected for 12 weeks(NB-12W) group. Another group was performed bilateral L6 nerves and cauda equine exposing but not transecting, which was sham-operation (Sham) group. Cystometry and renal ultrasound examination were performed and rats in each group were killed to collect the kidney and bladder tissues in NB-4W group at 4 weeks, in Sham group and NB-12W group at 12 weeks after operation. HE, Masson staining, immunohistochemical staining and western blot were used to detect histological changes, expression of transforming growth factor-β1(TGF-β1) and α-smooth muscle actin(α-SMA).Results:All rats in NB-4W and NB-12W group showed acontractile detrusor. In the NB-4W and NB-12W group, the maximum cystometric capacity [(5.84±0.33) ml and (3.13±0.35) ml], the detrusor leak point pressure [(25.41±0.86) cm H 2O and (27.36±2.04) cm H 2O] (1 cm H 2O = 0.098 kPa), were significantly higher than those in the Sham group [(0.98±0.14) ml, (7.13±0.90) cm H 2O, both P<0.05]. Compliance in NB-4W group [(0.28±0.21) ml/cm H 2O] and NB-12W group [(0.17±0.12) ml/cm H 2O] were significantly lower than that of the Sham group [(0.34±0.26) ml/cm H 2O], and the compliance of NB-12W group was lower than that of NB-4W group significantly (all P<0.05). HE staining of the bladder showed that the inflammatory cell infiltration was obvious in the NB-4W and NB-12W group. Bladder collagen volume fractions in NB-4W group [(30.5±1.5) %] and NB-12W group [(45.2±3.8) %] were both higher than that of Sham group [(20.7±2.2) %, both P<0.05]. The expression of TGF-β1 and α-SMA in the bladder tissue of NB-4W group were higher than those of sham group, and that of NB-12W group were higher than NB-4W group. In NB-4W group and NB-12W group, 3 (20.0 %) and 7 (46.7 %) rats were found hydronephrosis, respectively. Additionally, HE staining showed that the degree of renal tubule injury and the number of inflammatory cell infiltration in the NB-4W and NB-12W group were higher than those in the Sham group. Masson staining showed that the volume fraction of collagen in kidneys of NB-4W and NB-12W group were (13.1±1.4) % and (21.6±1.9) %, respectively, which were significantly higher than that in sham operation group [(4.6±0.7) %, both P<0.05]. Conclusions:Bilateral L6 + cauda equina nerve transecting can induce NB with hydronephrosis in parts of rats. The degree of bladder fibrosis gradually increased with the time of nerve transection, and the incidence and severity of UUTD also increased with the time of nerve transection.
