AIM: To investigate the effect of intravitreal injection of recombinant tissue plasminogen activator(r-TPA)before pars plana vitrectomy(PPV)on surgical outcomes in patients with rupture of the globe(RG).METHODS: A retrospective study was conducted on 37 patients(37 eyes)with RG who underwent PPV 7-10 d after Stage Ⅰ suturing and stabilization at our hospital between April 2020 and November 2023. Based on whether an intravitreal r-TPA injection was administered 1 d before PPV, patients were divided into two groups, with 14 cases(14 eyes)in pre-operative r-TPA injection group, and 23 cases(23 eyes)in control group without pre-operative r-TPA injection. The intraoperative retinal reattachment rate, intraoperative silicone oil application, postoperative intraocular rebleeding, postoperative hypotony, and best-corrected visual acuity(BCVA)were compared between the two groups.RESULTS: The baseline characteristics were comparable between the two groups(P>0.05). Significant differences were found between the two groups in the intraoperative retinal reattachment rate, the volume of silicone oil injected, and the proportion of BCVA(all P<0.05). No statistically significant differences were observed in the intraoperative silicone oil tamponade rate, postoperative intraocular rebleeding, or postoperative hypotony rates(all P>0.05).CONCLUSION: RG patients who received an intravitreal r-TPA injection 1 d before PPV demonstrated significantly higher intraoperative retinal reattachment rates and better postoperative visual acuity outcomes.

A 19-year-old male patient was admitted to a community hospital in Yangpu District of Shanghai in September 2023 due to diarrhea (4 times per day, watery stool) for 3 consecutive days. The patient had a history of eating out at a barbecue restaurant the night before the onset. The case accorded with diarrhea disease surveillance, and the pathogen was isolated as "non-A-F serogroup Salmonella" by the public health laboratory in the area where the patient′s feces swab was collected. The strain was identified as Salmonella Urbana ST512 by serological typing, antimicrobial resistance phenotype, and whole genome sequencing analysis in the Reference Lab, and then compared with the regional serotype database of Salmonella in China. At last, the patient was cured after taking levofloxacin orally for 3 days.

Anterior cruciate ligament reconstruction(ACLR)is the preferred treatment to restore the original activity level of patients.The single-leg drop jump can not only identify high-risk exercise strategies,but also provide a standard for the rehabilitation process of ACLR.In this review,a combined search of'single-leg drop jump''anterior cruciate ligament reconstruction''biomechanics'was conducted through CNKI,PubMed,Embase and other databases,and the biomechanical changes of single-leg drop jump after ACLR and related intervention method are summarized.The research findings will help adjust rehabilitation strategies after ACLR and avoid high-risk actions with secondary injuries.The analysis of single-leg drop jump after ACLR can guide clinicians and rehabilitation therapists to formulate and adjust rehabilitation treatment plan,improve the postoperative rehabilitation efficiency of ACLR,and help patients return to exercise early.

OBJECTIVE: To evaluate the effect of different cumulative energy composite parameters on the outcomes of phacoemulsification cataract surgery in patients with type 2 diabetes mellitus. METHODS: A total of 252 patients with cataract (involving 252 eyes) and type 2 diabetes mellitus received phacoemulsification cataract surgery in our hospital between January, 2017 and June, 2019. The patients were divided into group A (150 cases) and group B (102 cases) for cataract phacoemulsification with cumulative energy composite parameters of 8 and 10, respectively, and 90 nondiabetic patients received cataract phacoemulsification with a cumulative energy composite parameters of 10 served as the control. The macular thickness, best corrected visual acuity, visual acuity, and postoperative leakage in the 3 groups were evaluated at 1 week, 1 month, and 3 months after the surgery. RESULTS: The visual acuity was significantly improved after phacoemulsification better in all the 3 groups. At 3 months after the surgery, the proportions of patients with visual acuity ratio < 0.1 or >1.0, macular thickness, best corrected visual acuity and permeability differed significantly between groups A and B ( < 0.05), but not between group A and the control group ( > 0.05). At 1 month and 3 months after the surgery, the proportion of patients with visual acuity ratio < 0.1 was significantly lower and the rate of visual acuity ratio >1.0 was higher in group A than in group B. At 1 month after the operation, the total leakage rate in group A (31.1%) was higher than that in the control group (21.1%) but comparable with that in group B; at 3 months, the total leakage rates were significantly lower in group A than in group B (10.0% 32.4%, < 0.05), and the leakage resulted mainly from local and diffuse permeation. CONCLUSIONS Phacoemulsification can effectively improve the visual acuity of cataract patients especially in non-diabetic patients. A lower cumulative energy composite parameter achieves better outcomes in type 2 diabetic patients with cataract. The macular thickness, local infiltration and diffuse leakage can be used as indicators for assessing visual recovery and stabilization after phacoemulsification.
