AIM:To investigate the effect of ranibizumab on blood flow density in different regions of the macula in patients with macular edema(ME)secondary to ischemic and non-ischemic branch retinal vein occlusion(BRVO).METHODS:This retrospective study enrolled patients with BRVO-ME who were treated at the hospital from September 2019 to March 2021. Patients were divided into ischemic and non-ischemic groups based on fundus findings. All patients received intravitreal injections of ranibizumab once monthly for three consecutive months. Best corrected visual acuity(BCVA), central macular thickness(CMT), and macular blood flow density were measured before treatment and at 1 d, 1 wk, 1 and 3 mo after treatment.RESULTS: A total of 46 patients(46 eyes)with BRVO-ME were included, comprising 21 eyes in the ischemic group(7 males, 14 females; mean age 55.81±10.36 y)and 25 eyes in the non-ischemic group(11 males, 14 females; mean age 54.84±9.81 y). At 3 mo after treatment, BCVA(LogMAR)in the non-ischemic group was superior to that in the ischemic group(0.19±0.19 vs 0.38±0.27, P=0.009). Analysis of CMT changes showed that the reduction amplitude in the ischemic group was significantly greater than that in the non-ischemic group at both 1 and 3 mo after treatment(all P<0.05). Blood flow densities in the whole, parafoveal, and perifoveal regions of the superficial capillary plexus(SCP), as well as in the whole and perifoveal regions of the deep capillary plexus(DCP), were significantly lower in ischemic patients than in non-ischemic patients, while blood flow density in the foveal region of DCP was significantly higher in the ischemic group(all P<0.05).CONCLUSION: Ranibizumab is effective for both types of patients. Non-ischemic patients have a better long-term visual prognosis, and the advantage may be related to better blood flow perfusion patterns in specific areas 3 mo after treatment. Monitoring changes in blood flow density in these areas can help provide personalized treatment for patients.

Objective To explore the role of X chromosome encoded epigenetic regulator UTX in NK cell-mediated anti-tumor activity.Methods Male Ncr1-iCre mice were crossed with female UTXfl/fl mice to generate F1 Ncr1-iCre+UTXfl/-male mice,which were further crossed with female UTXfl/fl mice to obtain male Ncr1-iCre-UTX fl/-control mice(M-Con)and NK-specific deletion of UTX male mice Ncr1-iCre+UTXfl/-(M-KO),as well as female Ncr1-iCre-UTXfl/fl control mice(F-Con)and UTX-deficient female mice Ncr1-iCre+UTXfl/fl(F-KO).UTX-deficient mice were injected with melanoma cell line B16F10 via tail vein to observe pulmonary metastatic tumor nodules.Moreover,flow cytometry was applied to detect the proportion and quantity of pulmonary NK cells(CD3-CD19-NK1.1+),maturation makers KLRG1 and CD11b,activation receptors NKG2D and CD69,and effector molecules,including perforin,granzyme B,CD107a,and IFN-γ.Then pulmonary NK cells were sorted and co-cultured with B16F10 cells,and the apoptosis of the melanoma cells was measured with flow cytometry.Results Compared with the M-Con mice,the M-KO mice presented less number of pulmonary tumor nodules(P<0.05),increased proportion and quantity of NK cells in the tumor microenvironment(P<0.01),though no obvious changes in the ratio of NK maturation makers KLRG1 to CD11b,enhanced expression level of cytotoxic molecule perforin(P<0.01),but no changes in the expression of effector molecule granzyme B,degranulation marker CD107a and cytokine IFN-γ in NK cells.Co-culture of NK cells and B16F10 cells promoted the apoptosis of tumor cells(P<0.05).Compared with the F-Con mice,the F-KO mice had no statistical difference in the number of pulmonary tumor nodules,but larger proportion and number of NK cells(P<0.05),decreased ratio of KLRG1 to CD11b(P<0.01),elevated level of perforin but decreased levels of granzyme B,CD107a and IFN-γ in NK cells(P<0.01).The co-culture of NK cells and B16F10 cells reduced the apoptosis of tumor cells in F-KO female mice(P<0.05).Conclusion NK-specific deletion of UTX regulates pulmonary metastasis of melanoma in a sex-dependent manner.

Objective:To examine the influence of sarcopenia on the mid-term clinical outcomes of percutaneous vertebroplasty(PVP) in the management of osteoporotic vertebral compression fractures(OVCF).Methods:A retrospective case analysis method was adopted to analyze the clinical data of 102 patients with OVCF who underwent PVP in Beijing Daxing District Hospital of Integrated Chinese and Western Medicine from September 2020 to September 2022. Among them, there were 19 males and 83 females; the patients was (74.31±6.99) years, aged from 61 to 89 years. Using the skeletal muscle index (SMI) at the L3 vertebral level as the basis for grouping, with the diagnostic criteria of SMI<24.4 cm 2/m 2 for males and SMI<23.3 cm 2/m 2 for females. The 102 patients were divided into the sarcopenia group ( n=42) and the non-sarcopenia group ( n=60). The visual analog scale(VAS) scores for low back pain were recorded before surgery and at 3 days, 6 months, 1 year, 3 years after surgery; The oswestry disability index(ODI) was recorded at 6 months, 1 year, and 3 years after surgery; Bone mineral density (BMD) T-scores were recorded at 1 year and 3 years after surgery, and complications such as adjacent vertebral fractures were recorded. Measurement data with normal distribution were expressed as mean±standard deviation( ± s), and comparisons between groups were performed using the t-test. Count data were expressed as case and percentage (%), and comparisons between groups were performed using the chi-square test or Fisher′s exact test. Results:All patients in this study successfully completed the surgery and were followed up for 3 years. Compared with the preoperative baseline levels, the VAS for low back pain and ODI of patients in both groups decreased significantly at all postoperative time points, with statistically significant differences ( P<0.05). For patients in the sarcopenia group, the VAS for low back pain at 3 days, 6 months, 1 year, and 3 years after surgery were (2.50±1.04), (2.45±0.80), (2.17±0.79), (1.90±0.76) points, respectively. Those in the non-sarcopenia group were(2.02±0.68), (1.85±0.80), (1.78±0.61), (1.57±0.62) points, respectively, with a statistically significant difference between the two groups ( P<0.05). The ODI scores of the sarcopenia group at 6 months, 1 year, and 3 years postoperatively were (23.76±3.88)%, (23.05±4.33)%, (22.51±4.49)%, while those of the non-sarcopenia group were (21.68±4.51)%, (20.78±4.60)%, (20.30±4.44)%. The difference between the two groups was statistically significant ( P<0.05). The T-scores of femoral neck bone mineral density in the sarcopenia group at 1 year and 3 years after surgery were (-2.78±0.38), (-2.71±0.41), and those in the non-sarcopenia group were (-2.63±0.35), (-2.53±0.34), with a statistically significant intergroup difference ( P<0.05). For the T-scores of lumbar spine bone mineral density, the sarcopenia group had (-3.36±0.58), (-3.47±0.68) at 1 year and 3 years postoperatively, compared with (-3.12±0.59), (-2.91±0.53) in the non-sarcopenia group. The difference between the two groups was statistically significant ( P<0.05). Regarding the incidence of postoperative complications such as adjacent vertebral fractures, the sarcopenia group had a significantly higher incidence (19.0%) than the non-sarcopenia group (3.3%), with a statistically significant difference between the groups ( P<0.05). Conclusions:OVCF patients with sarcopenia who undergo PVP have poorer mid-term postoperative efficacy than those without sarcopenia, and they also face an increased risk of postoperative complications. Early screening and active intervention for patients with sarcopenia will help improve their clinical efficacy.

Objective To investigate the expression and prognostic value of heat shock protein B7(HSPB7)in gastric cancer.Methods Immunohistochemistry SP was used to detect HSPB7 and p53 protein expression in 73 cases of gastric cancer and adjacent normal tissues,and their relationships with clinicopatho-logical parameters were analyzed.Spearman's rank correlation analysis was performed to analyze their correla-tion.Kaplan-Meier survival curves and Log-rank tests were used for survival analysis,and a Cox proportional hazards model was applied to analyze prognostic factors.qPCR was used to determine HSPB7 mRNA expres-sion in 22 cases of gastric cancer and normal gastric tissues,and differences between cancer and normal tissues were analyzed.Data from The Cancer Genome Atlas(TCGA)database were used to further analyze HSPB7 mRNA expression differences between gastric cancer and normal tissues and their relationship with clinico-pathological parameters.Results HSPB7 was mainly localized in the cytoplasm,and its expression in gastric cancer tissues was significantly lower than that in adjacent normal tissues(P<0.05),and its expression in gastric cancer tissues was related to TNM stage,tumor invasion depth,differentiation degree and lymph node metastasis(P<0.05).The expression of p53 in gastric cancer was significantly higher than that in adjacent normal tissues(P<0.05),and the expression in gastric cancer tissues was correlated with TNM stage,tumor invasion depth and differentiation degree(P<0.05).Spearman rank correlation analysis showed that the ex-pressions of HSPB7 and p53 were negatively correlated in gastric cancer(r=-0.351,P=0.002).The 5-year survival rate of patients in the positive group was significantly higher than that in the negative group(χ2=10.611,P<0.001).Compared with gastric cancer tissues,the mRNA expression level of HSPB7 in adjacent normal tissues was significantly higher(t=-6.180,P<0.001).The results of bioinformatics analysis showed that the mRNA expression of HSPB7 in normal gastric samples was significantly higher than that in gastric cancer samples(P<0.001),and it was related to age,pathological stage and T stage(P<0.05).Conclusion HSPB7 protein is expressed at low levels in gastric cancer tissues,and it is closely related to the clinicopathological pa-rameters and prognosis of gastric cancer patients,which may be used as a predictive index of gastric cancer malignancy.In gastric cancer tissues,they may have antagonistic effects in tumor progression,and their related signaling pathways need to be further explored.

AIM: To investigate the influence of relevant inflammatory markers in peripheral blood on the progression of neovascular glaucoma(NVG)secondary to diabetic retinopathy(DR)patients.METHODS: Retrospective case-control study. Patients were categorized into two groups based on the presence or absence of NVG: those with proliferative diabetic retinopathy(PDR)alone(PDR group, n=148)and those with NVG secondary to PDR(NVG secondary to PDR group, n=142). Peripheral blood inflammatory markers were evaluated, including white blood cell-related indices, neutrophil-to-lymphocyte ratio(NLR), platelet-to-lymphocyte ratio(PLR), monocyte-to-lymphocyte ratio(MLR), and systemic immune-inflammation index(SII). The distinctions in peripheral blood inflammatory markers between the two groups of patients and their relationships with NVG secondary to PDR were analyzed.RESULTS:No statistically significant differences were observed in basic characteristics between the two groups, confirming their comparability. However, significant differences were found in eosinophil percentage and MLR between the PDR group and the NVG secondary to PDR group(all P<0.05), with both values being significantly higher in the NVG secondary to PDR group. Multivariate Logistic regression analysis revealed that the eosinophil percentage and the MLR were factors influencing the development of patients with NVG secondary to PDR.CONCLUSION: Eosinophil percentage and MLR may be associated with the progression of PDR to NVG, and could serve as potential predictive markers for NVG development in PDR patients.

OBJECTIVES: This study aims to analyze the clinical symptoms and imaging manifestations in patients with temporomandibular disorder syndrome (TMD), who are sensitive to sudden temperature drop. METHODS: One hundred and nineteen patients with TMD who attended the Department of Stomatology of the First Medical Center of Chinese People's Liberation Army General Hospital from December 2022 to December 2023 were included, including 44 males and 75 females, with a mean age of 32.4±13.7 years.The questionnaire was used to determine whether they were sensitive to temperature drop, and the TMD patients were divided into a temperature plunge-sensitive group and a temperature drop insensitive group. The clinical symptoms and imaging manifestations of patients in the two groups were observed. SPSS 25.0 was used for statistical analysis. RESULTS: There was no statistically significant difference between the gender and age of patients in the temperature plunge-sensitive group (50 patients) and the insensitivity group (69 patients) (P>0.05). The percentage of patients with pain was slightly higher in the temperature plunge-sensitive group [86.0% (43/50)] than in the insensitive group [68.1% (47/69)], and the difference was statistically significant (χ²=5.031, P=0.025), while the differences in joint murmur and mouth opening limitation between the two groups were not statistically significant. A total of 238 lateral joints were detected in both groups, the percentage of osteoarthropathic imaging changes was significantly higher in the temperature plunge-sensitive group [82.0% (82/100)] than in the insensitive group [53.6% (74/138)] (χ²=20.675, P<0.001). Magnetic imaging showed that the percentage of joint effusion was higher in patients in the temperature plunge-sensitive group [66.0% (33/50)] than in the insensitive group [42.0% (29/69)], and the difference was statistically significant (χ²=5.602, P=0.018). CONCLUSIONS TMD patients with maxillofacial pain symptoms, joint effusions, and abnormal imaging of osteoarticular structures are more likely to be sensitive to sudden temperature drops.

OBJECTIVES: This study aimed to investigate the correlation between clinical symptoms and unilateral chewing habits in patients with temporomandibular disorder (TMD) accompanied by tinnitus. METHODS: A total of 285 patients diagnosed with TMD at the Department of Stomatology of the First Medical Center of Chinese People's Liberation Army General Hospital between December 2020 and May 2024 were included and divided into two groups: tinnitus group and non-tinnitus group. Analysis was conducted on the proportion of patients with unilateral chewing habits in both groups, the correlation between the side of tinnitus and the side of unilateral chewing, and the correlation of tinnitus with TMD clinical symptoms (joint clicking, joint pain, and limited mouth opening) and unilateral chewing habits. The correlation of the type of disc displacement with unilateral chewing and tinnitus was also examined. RESULTS: In the tinnitus group, the proportions of patients with and without unilateral chewing habits were 90.70% (39/43) and 9.30% (4/43), respectively. In the non-tinnitus group, the proportions of patients with and without unilateral chewing habits were 76.03% (184/242) and 23.97% (58/242), respectively. The proportion of patients with unilateral chewing habits in the tinnitus group was significantly higher than in the non-tinnitus group (χ²=4.613, P<0.05). Correlation analysis showed a positive correlation between tinnitus and unilateral chewing habits (P<0.05). In the left-sided tinnitus group, the proportion of left-sided unilateral chewers [54.55% (12/22)] was higher than that of right-sided unilateral chewers [45.45% (10/22)]. In the right-sided tinnitus group, the proportion of right-sided unilateral chewers [81.82% (9/11)] was higher than that of left-sided unilateral chewers [18.18% (2/11)]. The difference was statistically significant (χ²=7.282, P<0.05). A positive correlation was also found between the side of tinnitus and the side of unilateral chewing habits (P<0.05). The proportion of patients with pain was significantly higher in the tinnitus group than in the non-tinnitus group (P<0.05). No significant difference in the proportion of joint clicking or limited mouth opening and disc displacement (no disc displacement, unilateral disc displacement, bilateral disc displacement, reducible disc displacement, or irreducible disc displacement) was found between the tinnitus and non-tinnitus groups (P>0.05). CONCLUSIONS TMD with unilateral chewing habits may be a contributing factor to unexplained tinnitus. Unexplained tinnitus is correlated with joint pain in patients with TMD.

Objective To identify the influencing factors of operation time of hand-assisted laparoscopic living donor nephrectomy, and to analyze the relationship between influencing factors and the severity of postoperative complications. Methods Clinical data of 91 donors who underwent hand-assisted laparoscopic nephrectomy were retrospectively analyzed. The correlation between preoperative baseline data of donors and operation time was analyzed. The relationship between operation time and postoperative complications was assessed and the threshold of operation time was determined. Results Multiple donor renal arteries, thick perirenal and posterior renal fat, metabolic syndrome, high Mayo adhesive probability (MAP) score and Clavien-Dindo score prolonged the operation time. By analyzing the receiver operating characteristic (ROC) curve, we found that when the operation time was ≥138 min, the incidence of postoperative complications of donors was significantly increased (P<0.05). Conclusions For donors with multiple renal arteries, thick perirenal and posterior renal fat, metabolic syndrome and high MAP score and Clavien-Dindo score, experienced surgeons should be selected to make adequate preoperative preparation and pay close attention after surgery, so as to timely detect postoperative complications and reduce the severity of complications, enhance clinical prognosis of the donors.
