AIM:To investigate the changes of retinal microcirculation after phacoemulsification and the influencing factors of visual acuity.METHODS: Retrospective analysis. A total of 264 cataract patients(264 eyes)who underwent phacoemulsification in our hospital from January 2022 to December 2022 were selected as the study objects. Patients were divided into < 0.3 group(66 eyes)and ≥0.3 group(198 eyes)according to the recovery of best corrected visual acuity(BCVA)at 3 mo after surgery. The changes of retinal microcirculation indexes were compared before and after treatment. Logistic regression and LASSO regression models were used to screen the influencing factors of postoperative BCVA. A nomogram prediction model of postoperative BCVA was constructed and verified. A restricted cubic spline Logistic regression model was established to analyze the dose-response relationship between end-diastolic velocity(EDV), peak systolic velocity(PSV)and the risk of BCVA recovery.RESULTS: At 3 mo postoperatively, EDV and PSV were significantly improved compared with those before treatment, and resistance index(RI)levels were significantly lower than those before treatment(all P<0.05). Preoperative EDV, PSV, aqueous humor cell grade, fundus lesion grade, advanced age and Emery grade were influencing factors for poor BCVA recovery after phacoemulsification in cataract patients(P<0.05). The AUC before and after validation of the nomogram model by Bootstrap method were 0.869(95%CI: 0.815-0.903)and 0.866(95%CI: 0.802-0.895), respectively. The sensitivity was 88.36% and 88.27%, and the specificity was 91.82% and 91.78%, respectively. Restricted cubic spline model analysis showed no nonlinear dose-response relationship between EDV and PSV levels and the risk of poor BCVA recovery in either male or female(P>0.05).CONCLUSION: After phacoemulsification, retinal microcirculation in cataract patients improved significantly. EDV, PSV, aqueous humor cell grade, fundus lesion grade, advanced age and Emery grade are all factors influencing poor BCVA recovery after cataract surgery.

Objective:To investigate the effects of external application of Sanying Plaster on the size of thyroid nodules and the states of depression and anxiety in patients with benign thyroid nodules.Methods:A randomized controlled trial was conducted. A total of 120 patients with benign thyroid nodules from the outpatient clinic of the Department of Thyroid Diseases at Shanghai Traditional Chinese Medicine Hospital from June to December 2022 were selected as the subjects of the study. They were divided into two groups using the random number table method, with 60 patients in each group. The control group received lifestyle intervention treatment, while the treatment group received Sanying Ointment in addition to the treatment of the control group. Both groups were treated for 3 months. TCM syndrome scores were measured before and after treatment; the maximum diameter of thyroid nodules was measured using a color Doppler ultrasound transverse section; the quality of life was assessed using the short form 36 (SF-36); the degree of anxiety and depression was evaluated using the self-rating anxiety scale (SAS) and the self-rating depression scale (SDS); adverse reactions during the treatment period were recorded, and the clinical efficacy was evaluated.Results:During the treatment period, 4 cases in the treatment group and 3 cases in the control group did not complete the treatment. Finally, 56 cases in the treatment group and 57 cases in the control group entered the efficacy evaluation. The total effective rate of the treatment group was 71.4% (40/56), and that of the control group was 14.0% (8/57), with a statistically significant difference between the two groups ( χ2=26.82, P<0.001). After treatment, the TCM syndrome score of the treatment group (10.02±3.65 vs. 16.65±3.44, t=-10.24) was lower than that of the control group ( P<0.001); the maximum diameter of thyroid nodules [11.00 (4.65, 19.93) mm vs. 15.00 (7.15, 28.50) mm, Z=-2.43] was lower than that of the control group ( P<0.05); the SF-36 score [121.83 (117.00, 130.00) vs. 114.42 (104.25, 127.50), Z=-2.62] was higher than that of the control group ( P<0.01); the SDS (46.72±4.59 vs. 57.02±5.99, t=14.80) and SAS (42.25±5.72 vs. 50.60±7.12, t=10.04) scores were lower than those in the control group ( P<0.001). The incidence of adverse reactions during the treatment period in the treatment group was 3.5% (2/57), and no adverse reactions occurred in the control group. Conclusion:The external application of Sanying Ointment helps to reduce the size of thyroid nodules in patients with benign thyroid nodules, improve the quality of life and anxiety and depression, and increase clinical efficacy with good safety.

This article discusses an education model that aims to contribute to students' growth and success and develop students' knowledge, abilities, and values based on the concept of outcome-based education (OBE). Under the guidance of this concept, measures have been taken from multiple dimensions, such as adopting a student-centered approach in theory course teaching, forming a team of teaching assistants, strengthening curriculum ideology and politics, optimizing curriculum content design, reforming teaching methods and teaching platforms, and enhancing feedback to teaching. Rehabilitation medicine courses taught with the OBE concept achieved better outcomes than those taught with conventional approaches adopted in the previous years, with satisfaction, acceptance, and recognition rates of higher than 95% among the students, as well as higher excellent and good rates in the end-of-semester tests compared with those of the same course last year. The preliminary exploration of the teaching reform under this model has provided reference for improving the quality of rehabilitation medicine teaching and cultivating modern professional talents in rehabilitation medicine.

Objective To analyze the risk factors of multi-drug resistant organism (MDRO) infection after liver transplantation. Methods The clinical data of 77 recipients undergoing liver transplantation were retrospectively analyzed. According to the incidence of MDRO infection, all recipients were divided into the non-MDRO infection group (n=51) and MDRO infection group (n=26). The infection rate and strain distribution of MDRO in liver transplant recipients were summarized. The risk factors of MDRO infection in liver transplant recipients were identified. Clinical prognosis of all recipients was statistically compared between two groups. Results The infection rate of MDRO after liver transplantation was 34% (26/77), mainly carbapenem-resistant MDRO infection. The main sites of infection included lung, abdominal cavity and incision. Univariate analysis showed that postoperative tracheal intubation ≥48 h, length of intensive care unit (ICU) stay ≥72 h, length of hospital stay ≥30 d, re-operation, continuous renal replacement therapy (CRRT) and tacrolimus (Tac) blood concentration ≥15 ng/mL were the risk factors for MDRO infection after liver transplantation. Cox regression analysis indicated that postoperative tracheal intubation≥48 h, re-operation, CRRT and Tac blood concentration ≥15 ng/mL were the independent risk factors for MDRO infection after liver transplantation. The fatality in the MDRO infection group was significantly higher than that in the non-MDRO infection group [31%(8/26) vs. 10%(5/51), P=0.01]. Conclusions Postoperative tracheal intubation ≥48 h, re-operation, CRRT and Tac blood concentration ≥15 ng/mL may increase the risk of MDRO infection after liver transplantation and affect clinical prognosis of the recipients.

Objective:To investigate the application of 3D printing technique in percutaneous nephrolithotomy (PCNL) of patients with complicated kidney stones.Methods:From January 2015 to December 2017, 60 patients with complicated kidney stones were enrolled in the First Affiliated Hospital of Hebei North University for prospective study, and PCNL was proposed.All the patients were randomly divided into 3D print group (30 cases) and conventional image inspection group (30 cases, control group). Before operation, CT urography (CTU) was used in both groups.In 3D printing group, digital imaging and communications in medicine (DICOM) files of CT were extracted for 3D image postprocessing, and thermoplastic materials were used to print 3D model.In the 3D printing group, the digital imaging and communications in medicine (DICOM) files of CT were extracted for 3D image post-processing, and the 3D model was printed with thermoplastic materials.According to the comprehensive planning of 3D kidney model, a virtual safe and reliable percutaneous renal access was established for each patient, and PCNL was executed.The patients in the two groups were compared before, during and after operation.Preoperative: age, sex, body mass index, blood creatinine, stone size and CT value.During the operation: (1) the target renal calices location time; (2) the conformity between the preoperative planning and the actual operation; (3) the operation completion time.After operation: (1) stone removal rate; (2) hemoglobin reduction level; (3) postoperative recovery.Results:All the 60 patients successfully completed the operation, 30 patients successfully printed out the 3D model, which can accurately express the relationship between the stone and the adjacent anatomical structure, the internal renal artery and the collecting system.Positioning time of 3D printing group in target renal calices((2.9 ± 1.5) min vs.(5.8 ± 1.7) min, P=0.023), coincidence between simulated and actual puncture calices((89.5 ± 3.5)% vs.(60.2 ± 5.7)%, P=0.005), postoperative stone removal rate ((89.9 ± 4.5)% vs.(75.9 ± 5.2)%, P=0.009), and hemoglobin levels((1.4 ± 0.5) g/L vs.(2.9 ± 1.4) g/L, P=0.032) were superior to the control group, and the difference was statistically significant.But there was no significant difference between the two groups (all P>0.05). Conclusion:The 3D printed kidney model truly restores the anatomical details around the kidneys and stones, providing a stereoscopic and intuitive way to perform surgery, so it maybe has a significance guidance for percutaneous nephrolithotomy.

Objective: To analyze the sensory processing characteristics among preschoolers with mental health problems in Nanshan District, Shenzhen. Methods: Random cluster sampling was used to select kindergartens for psychological screening from March to June 2018. The Strengths and Difficulties Questionnaire (SDQ) and the Simplified Sensory Questionnaire (SSP) were used to evaluate 6 365 preschool children. Results: A total of 15.15% preschoolers were detected with abnormal results. The SSP scores of preschoolers with emotional symptoms/conduct problems/prosocial behaviors were lower than normal preschoolers’(P<0.01). Among the preschoolers with hyperactivity-inattention, taste/smell sensitivity (F=12.45)/underresponsive/seeks sensation(F=102.44), auditory filtering(F=93.51), low energy/weak(F=13.33), visual/auditory sensitivity (F=4.32) scores were lower than normal preschoolers’(P<0.05), the scores of tactile sensitivity movement sensitivity were no statistical difference with normal preschoolers’. Among the preschoolers with peer problem, taste/smell sensitivity(F=5.86), tactile sensitivity(F=6.05), movement sensitivity(F=4.70), auditory filtering(F=17.32), low energy/weak (F=9.56), visual/auditory sensitivity (F=4.16) scores were lower than normal preschoolers’ (P<0.05), and the scores of under-esponsive/seeks sensation were no statistical difference with normal pre-schoolers’. Prosocial behavior and tactile (r=0.30), under-responsive/seeks sensation(r=0.37), auditory filtering(r=0.37), low energy/weak (r=0.31) were positive associated(P<0.01). Emotional symptoms were negatively associated with lack of energy/weakness(r=-0.33, P<0.01). Conclusion Mental health problems are related to sensory processing ability in preschoolers. Preschoolers with mental health problems have weak sensory processing ability. Clinicians and occupational therapists should pay attention to evaluation and intervention of sensory processing ability in preschoolers with mental health problems.
