AIM: To evaluate the safety and efficacy of low-dose transscleral cyclophotocoagulation(TSCP)in the management of persistent ocular hypertension after an acute attack of angle-closure glaucoma(AACG).METHODS:This retrospective study enrolled patients diagnosed with persistent ocular hypertension after an acute AACG attack at the No.988 Hospital of the Joint Logistics Support Force of the Chinese PLA between September 2023 and September 2024. All patients underwent low-dose TSCP using a semiconductor diode laser. Subsequent cataract surgery combined with goniosynechialysis was performed once intraocular pressure(IOP)was stabilized. Changes in anterior chamber depth(ACD), best-corrected visual acuity(VA), and IOP were compared before and after TSCP, as well as before and after phacoemulsification. Post-TSCP complications were also documented.RESULTS: A total of 21 patients(21 eyes)were enrolled, including 8 males and 13 females, with a mean age of 67.95±7.25 y. Compared with pre-cyclophotocoagulation values, ACD increased significantly at 3 d post-TSCP(1.49±0.18 vs 1.22±0.21 mm; P<0.001). BCVA and IOP decreased significantly at 1 d post-TSCP, pre-phacoemulsification, 1 wk post-phacoemulsification, and 1 mo post-phacoemulsification compared with pre-TSCP IOP(all P<0.01). Regarding postoperative complications, 2 eyes experienced pain on the day of the procedure, 5 eyes developed mild corneal endothelial folds, 2 eyes exhibited moderate anterior chamber inflammatory reaction, and 12 eyes showed shallow ciliary body detachment. No serious complications occurred during the 1-month follow-up period.CONCLUSION:Low-dose TSCP appears to be an effective bridging therapy for patients with persistent ocular hypertension following an AACG attack. It facilitates rapid IOP reduction, alleviates symptoms, and helps preserve visual function with a favorable safety profile, thereby reducing the risks associated with subsequent intraocular surgery.

Objective:To investigate the efficacy and safety of percutaneous trans-hepatic choledochoscopic lithotripsy (PTCSL) in the treatment of recurrent hepatobiliary calculi under enhanced recovery after surgery (ERAS) mode.Methods:Clinical data of 88 patients with recurrent hepatobiliary calculi, who were treated with PTCSL at Zhengzhou Central Hospital Affiliated to Zhengzhou University and the First Affiliated Hospital of Xi'an Jiaotong University between June 2022 and June 2024 were retrospectively analyzed, including 34 males and 54 females, aged (52.0±13.8) years. The scheme includes preoperative education, prophylactic antibiotic application, ensuring the quality of surgery, early postoperative feeding and activity, etc. The operation can be divided into two fashions: percutaneous transhepatic cholangial drainage and PTCSL, which can be completed in one stage (one-stage expansion method) or in two stages (staged expansion method). Clinical data such as gender, age, operative time, intraoperative blood loss, residual stone, and surgical complications were recorded.Results:All 88 patients underwent PTCSL under ERAS mode successfully, including 52 cases using one-stage expansion method and 36 cases using staged expansion method. The operative time was (53±20) min, the intraoperative blood loss was (9.7±3.8) ml, the postoperative hospital stay was (3.6±1.7) d, and the hospitalization cost was (17 500±4 700) yuan. Sixty-nine patients (78.4%, 69/88) had one-time stone removal in the first PTCSL. A total of 19 cases of residual stones were managed again by percutaneous sinus soft choledochoscopy, of which 12 cases were managed by one-time choledochoscopy, five cases by two-time choledochoscopy, and two cases by three-time choledochoscopy. The rate of residual stone was significantly higher in one-stage expansion method compared to staged expansion method [28.8% (15/52) vs. 11.1% (4/36), P=0.040]. No death, conversion to open surgery, or severe complications such as intra-abdominal hemorrhage or bile leakage occurred in the patients. No residual stones or recurrence were found during the follow-ups of (7.5±2.1) months after discharge. Conclusion:PTCSL under ERAS mode is safe and effective in the treatment of recurrent hepatobiliary calculi.

Antimicrobial resistance(AMR)has been a difficult problem of globally public health that can threaten human health.If its spread could not be effectively curbed,it will lead to increasing limitation in the options of clinical treatment.In the increasingly complex environment of diagnosis and treatment of infectious diseases,it is particularly urgent to build a rapid,accurate and widely popularized diagnosis system for pathogen,which is the key prerequisite of realizing accurate assessment for susceptibility of antimicrobial drug.This article comprehensively reviewed the main rapid diagnostic techniques currently used in AMR monitoring and detecting for antimicrobial susceptibility on the basis of the above conditions.It not only provided a detailed analysis of molecular typing methods represented by gene sequencing and phenotype identification methods based on conventional culture,but also focused on a new joint diagnostic strategy that combined genomic information with functional verification.Through comparative study for various technical principles,operating procedures and clinical applicability,the purpose of this paper was to provide scientific basis for optimizing the rapid detection scheme of drug susceptibility in clinical microbiology laboratories,and promote a comprehensive improvement of the level of diagnosis and treatment for infectious diseases,and ultimately improve the multi-layered network system of prevention and control for nosocomial infection.

Objective:To investigate the effects of prophylactic analgesia using erector spinae plane block (ESPB) combined with ketorolac tromethamine on postoperative analgesia and early recovery of patients undergoing laparoscopic radical gastrectomy.Methods:A prospective randomized controlled study was conducted. A total of 105 gastric cancer patients who underwent laparoscopic radical gastrectomy in Heji Hospital Affiliated to Changzhi Medical College from June 2022 to October 2023 were selected, and the patients were divided into ESPB+ketorolac tromethamine group (T group), ESPB group (C1 group), and ketorolac tromethamine group (C2 group) by using the random number table method, with 35 cases in each group. The prophylactic analgesia method was preoperative ESPB + ketorolac tromethamine in T group, preoperative ESPB in C1 group and preoperative ketorolac tromethamine in C2 group. The intraoperative sufentanil and remifentanil dosage and the postoperative resting pain visual analogue scale (VAS) score, remedial analgesia, recovery status and complication occurrence were compared among the 3 groups.Results:The baseline characteristics and intraoperative conditions of the patients in the 3 groups were compared, and the differences were not statistically significant (all P > 0.05). The intraoperative sufentanil dosage in T group was less than that in C1 and C2 groups [30 (25, 30) μg vs. 35 (30, 35) μg vs. 40 (35, 45) μg], and the difference was statistically significant ( Z = 33.03, P < 0.001); the intraoperative remifentanil dosage in T group was less than that in C1 and C2 groups [0.34 (0.30, 0.40) mg vs. 0.40 (0.30, 0.50) mg vs. 0.70 (0.60, 0.85) mg], and the difference was statistically significant ( Z = 53.84, P < 0.001). The VAS scores at 1, 6, 12, 24, 48 h after surgery in T group were lower than those in C1 and C2 groups, and the differences were statistically significant (all P < 0.001). The press number of analgesic pump in T group was less than that in C1 and C2 groups [1 (0, 2) times vs. 2 (1, 2) times vs. 4 (3, 5) times], and the difference was statistically significant ( Z = 48.10, P < 0.001). The postoperative first time of exhaust and get out of bed and days of hospital stay in T group were shorter than those in C1 and C2 groups, and the differences were statistically significant (all P < 0.001). The differences in the incidence of postoperative nausea and vomiting, dizziness, pruritus, pneumonia, and anastomotic fistula among the 3 groups were not statistically significant (all P > 0.05). None of the 3 groups experienced postoperative drowsiness, hypotension or respiratory depression. Conclusions:Prophylactic analgesia using ESPB combined with ketorolac tromethamine can effectively reduce the postoperative pain of patients undergoing laparoscopic radical gastrectomy, reduce the use of analgesic drugs, and promote the early recovery of the patients in the postoperative period without increasing the postoperative complications.

AIM: To compare the effectiveness of foldable capsular body(FCB)with traditional scleral buckling(SB)in the treatment of experimental retinal detachment animal models.METHODS: After successfully establishing rhegmatogenous retinal detachment(RRD)animal models, 24 New Zealand white rabbits were randomly divided into three groups(RRD models group, SB group, and FCB group), with 8 rabbits in each group. The FCB and SB groups underwent SB and FCB surgeries for the RRD animal models, while the RRD models group only consists of RRD models without any surgical intervention during the follow-up period. The follow-up duration was 3 mo. Wide-field neonatal fundus imaging system and ophthalmic B-ultrasound were used to assess the fundus conditions before and after surgery. The Icare® TONOVET Plus tonometer was utilized to evaluate intraocular pressure changes before and after surgery. The Eaton and Draize scoring systems were selected to monitor postoperative inflammatory reactions.RESULTS: The retinal reattachment rates in the FCB and SB groups were 87.5% and 75.0%, respectively, with no statistically significant difference between the groups(P>0.05). The intraocular pressure in both the FCB and SB groups increased postoperatively compared to preoperative levels(P<0.01), and there were no significant differences in intraocular pressure at any time points during the follow-up period between the groups(P>0.05). The intraocular pressure in the RRD models group remained at a low level throughout the follow-up period. The average surgical time for the FCB group was 16.87±2.29 min, which was shorter than 46.25±4.74 min in the SB group(t=-15.166, P<0.001). According to the Eaton and Draize scoring systems, the FCB group had lower grades of conjunctival hyperemia and edema in the early postoperative period compared to the SB group, indicating milder inflammatory reactions(P<0.05).CONCLUSION: Both FCB and SB are effective in treating experimental RRD. Compared to SB, FCB is simpler to operate, and also has a shorter surgical time and milder postoperative inflammatory reactions.

Lens injury is an important etiological factor in the reduction of visual function following ocular trauma.Currently, there are no clear standards for the classification of lens injury, and comprehensive diagnostic tools are lacking.This deficiency leads to numerous controversies and challenges in critical areas, such as diagnosis and preoperative evalution, timing of surgery, surgical strategy, and assessment of postoperative prognosis.Tomographic imaging technology, such as computed tomography, magnetic resonance imaging, optical coherence tomography, has introduced a new dimension to the evaluation of lens injury, which is crucial for assessing the transparency, texture, location, morphology, and integrity of the lens, as well as the zonules and nearby intraocular structures.However, the use of tomographic imaging technology is somewhat limited due to the limitations of relying on a single method.With the ongoing advancement of imaging technologies and the rapid development of big data and artificial intelligence, tomographic imaging will become an increasingly essential tool in the future management of lens injury.Our expert group reviewed the epidemiological characteristics and classification of lens injury and the major challenges currently faced in the diagnosis and treatment of lens injury, and provided expert recommendations mainly focusing on the application, shortcomings and limitations of current tomographic imaging technology in the diagnosis and treatment of lens injury, and future development directions.

Objective:To investigate the surgical technique and initial outcomes of distal derotational femoral osteotomy (DDFO) combined with knee extension device reconstruction in adolescents with habitual patellar dislocation and severe lower limb torsional deformity.Methods:A retrospective study was conducted on 10 adolescent patients (12 knees) treated at Beijing Jishuitan Hospital and its Guizhou branch from June 2016 to June 2022. There were 6 males and 4 females with an average age of 12.0±1.5 years (range: 10.0-14.5 years) Surgical treatment included DDFO and knee extension device reconstruction (lateral retinacular release, medial retinacular plication, Roux-Goldthwait distal realignment, and MPFL reconstruction). Clinical outcomes were assessed using Lysholm scores, incidence of redislocation and complications, and imaging parameters (lateral patellofemoral angle, Insall-Salvati index, TT-TG distance, and femoral anteversion angle) preoperatively and at 1 year postoperatively.Results:All 12 knees were successfully operated on, with an average surgery time of 2.0±0.5 h (range 1.0-2.5 h), intraoperative blood loss of 47.1±17.1 ml (range 20-80 ml), and follow-up time of 46.2±18.7 months (range 24-72 months). The Lysholm knee score improved from 58.25±8.80 preoperatively to 89.17±5.32 at final follow-up ( t=-9.096, P<0.001) with significant difference. The lateral patellofemoral angle improved from -64.92±4.68 preoperatively to 6.08±2.27 at final follow-up ( t=39.178, P<0.001) with significant difference. The femoral anteversion angle decreased from 34.08±3.06 preoperatively to 14.50±2.65 at final follow-up ( t=16.916, P<0.001) with significant difference. No patellar redislocation, skin necrosis, wound infection, or limited joint mobility occurred during follow-up. Conclusion:DDFO combined with knee extension device reconstruction is an effective and safe treatment for adolescent habitual patellar dislocation with severe torsional deformity, resulting in significant clinical and radiographic improvement with low complication rates.

Objective:To observe the curative effect of a personalized surgical scheme based on scanning source optical coherence tomography (SS-OCT) image features in the treatment of congenital optic disc pit (ODP) with maculopathy (ODP-M).Methods:A prospective interventional cohort study. From September 2019 to May 2024, 15 patients with 15 eyes who were diagnosed with ODP-M by ophthalmology examination in Department of Ophthalmonogy of The First Affiliated Hospital of Zhengzhou University were included in the study. Best corrected visual acuity (BCVA) and SS-OCT were performed in all affected eyes. Standard E word visual acuity chart was used for BCVA examination, which was converted into logarithm of the minimum angle of resolution (logMAR) BCVA for record. The center retinal thickness (CRT) was measured by SS-OCT examination of macular area using VG200D of Henan SVision Imaging Technology Co., LTD. According to the morphological characteristics of ODP and the splitting, edema and detachment of macular region, combined with the degree of pulling of the boundary membrane between the posterior vitreous cortex and macular region, a personalized surgical method was designed. Class I: pars plana vitrectomy combined with macular boundary film stripping, ODP boundary film packing and vitreous cavity gas filling. Class Ⅱ: pars plana vitrectomy combined with non-retained macular boundary film stripping or ODP inner boundary film packing, vitreous cavity gas filling. Class Ⅰ and Class Ⅱ operations were performed in 10 and 5 eyes of 15 eyes, respectively. The postoperative follow-up time was >6 months. Follow-up time was performed with the same equipment before surgery. BCVA changes, CRT reduction rate and complications were observed. BCVA and CRT were compared before and after operation by paired sample t test. Results:There were 15 eyes in 15 cases, 4 eyes in 4 males and 11 eyes in 11 females. The age was (28.87±16.5) years. logMAR BCVA of the affected eye was 0.94±0.51. CRT was (697.80±301.80) μm. At the last follow-up, the logMAR BCVA was 0.53±0.49. CRT was (392.53±167.55) μm. Compared with before operation, BCVA and CRT were significantly improved, and the difference was statistically significant ( t=3.23, 3.25; P=0.006, 0.006). After surgery, transient intraocular hypertension occurred in 2 eyes, and the intraocular pressure returned to normal level after 3 to 7 days without special treatment. Two eyes underwent an unexpected second operation. Among them, one eye underwent Class Ⅰ surgery, the tunnel at ODP was closed after surgery, and there was a small amount of subretinal fluid in the macular area. Class Ⅱ surgery was performed in 1 eye with retinal reattachment. Conclusion:Personalized surgical treatment of ODP-M based on SS-OCT image features can reduce CRT and improve visual acuity.
