OBJECTIVE: To summarize the effectiveness of orthopedic surgery for patients with moderate and severe hallux valgus and analyze its related influencing factors. METHODS: A clinical data of 247 patients (287 feet) with moderate and severe hallux valgus, who were admitted between January 2013 and October 2024 and met the selection criteria, was retrospectively analyzed. There were 39 males and 208 females, with a median age of 57 years (range, 19-89 years). There were 207 cases of single-foot involvement and 40 cases of double-foot involvement; 159 feet were moderate hallux valgus and 128 feet were severe hallux valgus. The disease duration ranged from 3 months to 25 years, with a median of 5 years and 8 months. The hallux valgus angle (HVA), the intermetatarsal angle (IMA), proximal articular set angle (PASA), and the American Orthopaedic Foot and Ankle Society (AOFAS) scores were measured before operation and at 6 months after operation, and the differences (change values) between pre- and post-operation were calculated. All patients were grouped according to the degree of preoperative hallux valgus deformity and age, and the patients with severe hallux valgus according to different surgical procedures, and the change values of HVA, IMA, and AOFAS scores were compared between groups. All patients were grouped according to postoperative HVA, then the postoperative AOFAS scores were compared between groups. RESULTS: All patients successfully completed the operations and were followed up 6 months to 11 years and 3 months, with an average of 4 years and 6 months. The HVA, IMA, PASA, and AOFAS scores at 6 months after operation showed significant improvement compared to preoperative levels, and the differences were significant ( P<0.05). The patients with severe hallux valgus had the higher change values of HVA, IMA, and AOFAS scores than the patients with moderate hallux valgus ( P<0.05). The elderly patients had the highest change values of HVA and AOFAS scores than the young and middle-aged patients ( P<0.05). The patients with postoperative HVA ranging from 0° to 5° had the highest AOFAS scores than the other patients at 6 months after operation ( P<0.05). Among different surgical procedures for severe hallux valgus, the metatarsophalangeal joint fusion had the highest change value of HVA, the Scarf osteotomy had the highest performance in correcting the IMA, and the first metatarsal base osteotomy had the highest improvement in the postoperative AOFAS score, and the differences were significant ( P<0.05). CONCLUSION Elderly patients show the better improvement in HVA and foot function after operation. The first metatarsal base osteotomy show the better improvement in foot function than other surgical procedures. A certain HVA is allowed to remain after hallux valgus correction, and the postoperative AOFAS score is higher when the corrected HVA is in the range of 0°-5°.

Objective To observe the effects of Edaravone Dexborneol combined with Tirofiban on early neurological deterioration(END)in patients with acute perforator artery infarction.Methods From October 2021 to October 2022,110 patients with acute perforator artery infarction hospitalized in the Department of Neurology of our hospital were selected.According to the random number table method,the patients were divided into control group and observation group.The control group was treated with Tirofiban injection,and on the treatment basis of control group,Edaravone Dexanetol was added in the observation group.The NIHSS score was evaluated on the first day and the third day after admission,and the incidence of END was compared between the two groups.The influencing factors of END were analyzed.Results The incidence of END in the control group was 25.45％,which was significantly higher than that in observation group(5.45％)(x2=8.419,P=0.004).Multivariate Logistic regression analysis showed that diabetes,high NIHSS score and high high-sensitivity C-reactive protein level at admission were risk factors for END in patients with perforator artery infarction,while Edaravone Dexborneol combined with Tirofiban treatment was a protective factor(all P＜0.05).There was no significant difference in the incidence of adverse reactions between the two groups(x2=0.785,P=0.376).Conclusions Edaravone Dexborneol combined with Tirofiban can reduce the incidence of END events in patients with perforator artery infarction and has good safety.Inflammation may be an independent risk factor for END events in perforator artery infarction.

[Objective]To evaluate the application of prostate-specific membrane antigen(PSMA)PET/CT in prostate biopsy screening,and propose effective strategies for prostate biopsy decision making based on PSMA PET/CT detection.[Methods]A retrospective analysis was conducted on PSMA PET/CT imaging and clinical pathological data from 155 patients with suspected prostate cancer between January 2020 and December 2023.PRIMARY score was used as the standardized evaluation method for PSMA PET/CT in the diagnosis of prostate cancer.And compared the positive prostate biopsy rates,missed diagnosis rates and biopsy reduction rates were compared regarding different PRIMARY scores.Receiver operating characteristic(ROC)curves were used to analyze prostate-specific antigen(PSA)and its derived parameters and identify the most suitable supplementary screening indicators for combined use with the PRIMARY score.[Results]Among patients with PRIMARY scores of 1 to 5,the proportions of patients diagnosed with prostate cancer were 15.8%(3/19),17.1%(7/41),50%(12/24),95.2%(20/21)and 98%(49/50),respectively.Using PRIMARY score of 3-5 as the biopsy screening strategy resulted in a positive prostate biopsy rate of 85.3%and biopsy reduction rate of 38.7%,but a missed diagnosis rate of 11%.PSA density>0.15 ng/(mL·cm3)was selected as a supplementary screening criterion to detect prostate cancer from patients with PRIMARY scores of 1-2.The combined application of the above two screening criteria reduced the missed diagnosis rate to 2.2%.[Conclusion]This study proposes a novel biopsy screening strategy for suspected prostate cancer patients using PSMA PET/CT,that is,a PRIMARY score of 3-5 or a PRIMARY score of 1-2 but PSA density>0.15 ng/(mL·cm3),which can effectively avoid unnecessary biopsies and significantly reduce the missed diagnosis rate.

Objective:To compare the effectiveness and safety profile of tenofovir amibufenamide (TMF) and tenofovir alafenamide (TAF), especially the effects on lipid metabolism in the treatment of chronic hepatitis B.Methods:A retrospective study was conducted on the virological response rate, biochemical response rate, renal function indicators, and lipid metabolism status of 159 cases with chronic hepatitis B (72 cases with TMF and 87 cases with TAF) after 48 weeks of antiviral treatment. The effects of the two drugs on lipid metabolism were further explored through cell and animal experiments.Results:There were no statistically significant differences in baseline age, gender ratio, treatment-na?ve and treatment-experienced proportions, hepatitis B virus (HBV) DNA and aminotransferase levels, renal function indicators, and serum lipid levels between the two groups. The levels of HBV DNA and transaminase were significantly reduced after 48 weeks of treatment in both groups. However, there were no statistically significant differences in virological response (84.2% vs. 75.8%, χ2=0.733, P=0.392) and biochemical response rate (86.1% vs. 85.1%, χ2=0.035, P=0.851) between the two groups. There was no significant change in the renal function index levels before and after treatment between the two groups of patients.

HepG2 cells were interfered with 10 μg/ml TMF and TAF for 72 hours, respectively. Microscopic examination revealed that in the TMF group [12 196 (10 740, 14 345) vs. 4 029 (3 086, 5 425) cells, Z=-4.815, P<0.001] and TAF group [12 484 (11 176, 15 824) vs. 4 029 (3 086, 5 425), Z=-4.815, P<0.001], the number of intracellular lipid droplets was higher than that in the control group after Oil Red O staining, but the difference between the two groups was not statistically significant. Ten-week-old C57/BL6J male mice were given 3.8 mg/kg TMF or TAF by continuous gavage for 12 weeks. The liver tissue was stained with Oil Red O. The number of lipid droplets was higher in the liver tissue of mice in the TAF group than that of the control group [30 647 (28 050, 34 821) and 27 614 (25 214, 29 176), Z=-2.529, P=0.011], while the difference between the TMF group and control group was not statistically significant. The serum TG levels were higher in the TAF group mice [1.17 (1.11, 1.19) μmol/L vs. 1.06 (1.04, 1.09) μmol/L, Z=-2.060, P=0.039], TC [2.58 (2.55, 2.80) μmol/L L vs. 2.33 (2.18, 2.54) μmol/L, Z=-2.084, P=0.037] than those of the control group after drug administration, while HDL-C levels were lower than those of the control group [1.14 (1.13, 1.16) μmol/L vs. 1.29 (1.28, 1.32) μmol/L, Z=-2.313, P=0.021] and TMF group [1.14 (1.13, 1.16) μmol/L vs. 1.30 (1.28, 1.38) μmol/L, Z=-2.795, P=0.005]. However, there was no statistically significant difference in TG, TC, and HDL-C levels between the TMF and the control group. Conclusion:Both TMF and TAF can effectively inhibit HBV replication and promote liver function recovery, with no significant impact on renal function. However, TAF may generate an adverse effect on lipid metabolism in the body, while TMF has no obvious effect.
