Otitis media is an infection of the middle ear mainly caused by bacteria, and current treatments rely heavily on antibiotics. However, the emergence of antibiotic-resistant bacterial strains seriously affects their efficacy. In our study, we found that extracellular vesicles (EVs) derived from human natural killer cells (NKs) inhibit the proliferation of both standard and levofloxacin (LVX)-resistant strains of Staphylococcus aureus in a dose-dependent manner. Moreover, compared to LVX, EVs were more effective at reducing effusion and rescuing hearing thresholds in animal models. For LVX-sensitive strains, EVs were significantly more effective in terms of curative time but not curative rate. For LVX-resistant strains, EVs were significantly more effective in terms of both curative rate and curative time when applied alone or applied jointly with LVX. In summary, we found that NK EVs are highly effective in treating otitis media, providing an alternative approach for treating this common disease.

Objective:To investigate the efficacy of virtual simulation-guided unilateral locking plate combined with Jail screw technique for double column tibial plateau fractures involving the posterolateral plateau.Methods:A retrospective case series study was conducted to analyze the clinical data of 32 patients with double column tibial plateau fractures involving the posterolateral plateau admitted to Nanjing Drum Tower Hospital Group Suqian Hospital from March 2018 to March 2022, including 20 males and 12 females, aged 37-69 years [(47.5±6.9)years]. According to AO/OTA classification, the fractures were classified as type 41B in 17 patients and type 41C in 15. According to the three-column classification, the fractures were classified as lateral column+posterior column in 17 patients and medial column+posterior column in 15. Virtual simulation technique was used to simulate surgical operation before surgery. After reduction, the patients′ tibial plateau mirror models of the healthy side were used to simulate the implantation of internal fixators on the affected side. The position data of the placed internal fixators were obtained to guide the personalized treatment with unilateral locking plate combined with Jail screw technique. The total number of Jail screws, average number of Jail screws, distribution and accuracy of screw placement, operative duration, intraoperative blood loss, and fracture healing status were recorded. The posterior tibial plateau angle (PTSA), proximal medial tibial angle (MPTA) and Rasmussen anatomical score were compared before operation, at 1, 3, 6, 12 months after operation and at the last follow-up. The Lysholm scores at 6, 12 months after operation and at the last follow-up were used to evaluate the knee function. At the last follow-up, the knee range of motion was measured. Postoperative complications were observed.Results:All the patients were followed up for 28-36 months [(30.7±2.3)months]. The total number of Jail screws inserted was 48, with an average of (1.5±0.5) screws. In the sagittal direction, 1-2 Jail screws were inserted in each patient, with an accuracy rate of 88% (42/48). The operative duration was 78-116 minutes [(98.7±10.5)minutes]. The intraoperative blood loss was 70-120 ml [(96.6±15.6)ml]. All the fractures had healing of stage I, with a healing time of 4-7 months [(5.4±0.9)months]. At 1, 3, 6, 12 months after operation and at last follow-up, the PTSA, MPTA, and Rasmussen anatomical scores were significantly improved when compared with those before operation ( P<0.05), while there was no statistically significant difference between those at various postoperative time points ( P>0.05). The Lysholm knee scores were (83.6±3.9)points, (88.5±3.6)points, and (93.7±2.6)points at 6, 12 months after operation, and at the last follow-up, respectively, which were gradually increased with the passage of the follow-up time ( P<0.05). The range of motion was (121.4±4.6)° in flexion and was 0.0(0.0, 3.0)° in extension at the last follow-up. Two patients had superficial wound infection and 1 had wound dehiscence after operation, which recovered with dressing change or debridement and suturing. No deep infection, vascular injury or nerve damage occurred. Conclusions:The virtual simulation-guided unilateral locking plate combined with Jail screw technique has the advantages of high accuracy of screw placement, shorter operative duration, less intraoperative blood loss, satisfactory fracture reduction, favorable recovery of knee function and range of motion, and fewer postoperative complications in the treatment of double column tibial plateau fractures involving the posterolateral plateau.

ObjectiveTo investigate the accuracy of multiple discriminant analysis （MDA） versus fibrosis-4 （FIB-4） in assessing liver fibrosis degree in patients with HBV infection， as well as the possibility of MDA as an indicator for disease progression. MethodsA total of 263 patients with HBV infection who underwent liver biopsy in The First Affiliated Hospital of Guangxi Medical University from April 2010 to April 2024 were included， and their clinical data were collected. According to the results of pathological examination， they were divided into non-significant fibrosis group （F<2） with 126 patients and significant fibrosis group （F≥2） with 137 patients. The correlation of MDA and FIB-4 with liver fibrosis degree was analyzed， and MDA and FIB-4 were compared in terms of their accuracy in assessing significant liver fibrosis. A total of 62 patients completed follow-up， and according to the presence or absence of progression to liver cirrhosis at the last follow-up visit， they were divided into progressive group with 21 patients and non-progressive group with 41 patients； the efficacy of MDA and FIB-4 in diagnosing disease progression was analyzed and compared. The independent-samples t test was used for comparison of normally distributed continuous data between groups， and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups； the Kruskal-Wallis H test was used for comparison between multiple groups， and the Bonferroni method was used for further comparison between two groups. The chi-square test was used for comparison of categorical data. The Spearman’s correlation coefficient was used for correlation analysis. The Wilcoxon signed rank sum test was used for the analysis of baseline data and data at the end of follow-up， and the binary Logistic regression analysis was used to investigate the influencing factors for progression to liver cirrhosis. The receiver operating characteristic （ROC） curve was used to investigate the diagnostic efficacy of indicators， the Z-test was used for comparison of the area under the ROC curve （AUC）， and the paired chi-square test was used for comparison of the sensitivity， specificity， and accuracy of the two indicators. ResultsThe correlation coefficient between FIB-4 and liver fibrosis degree was 0.378， while the correlation coefficient between MDA and liver fibrosis degree was -0.325 （both P<0.001）. FIB-4 had an AUC of 0.688， a sensitivity of 64.96%， a specificity of 68.87%， a positive predictive value of 67.42%， a negative predictive value of 63.36%， an accuracy of 65.40%， and a cut-off value of 1.01， while MDA had an AUC of 0.653， a sensitivity of 52.55%， a specificity of 78.57%， a positive predictive value of 72.73%， a negative predictive value of 60.37%， an accuracy of 65.02%， and a cut-off value of 0.29， suggesting that compared with FIB-4， MDA had a lower sensitivity （P=0.004） and a higher specificity （P=0.001）. The progressive group had a significantly higher age than the non-progressive group at baseline （t=2.611， P=0.011）. For the progressive group， there was an increase in FIB-4 and a reduction in MDA from baseline to the end of follow-up （both P<0.001）， while the non-progressive group showed no significant changes （both P>0.05）. The multivariate Logistic regression analysis showed that aspartate aminotransferase （odds ratio ［OR］=0.940， 95% confidence interval ［CI］： 0.885‍ ‍—‍ ‍0.998， P<0.05） and MDA （OR=0.445， 95%CI： 0.279‍ ‍—‍ ‍0.710， P<0.001） were independent influencing factors for disease progression. MDA had an AUC of 0.893 and an optimal cut-off value of -0.01 in diagnosing the disease progression of liver cirrhosis. ConclusionMDA has a comparable accuracy to FIB-4 in the diagnosis of significant liver fibrosis， and MDA<-0.01 has a high accuracy in diagnosing the progression of liver fibrosis to liver cirrhosis， which can help to reduce the need for liver biopsy in clinical practice.

Objective To investigate the clinical diagnostic value of extra-spindle pole-like protein 1(ESPL1)in the progression of hepatitis B virus(HBV)-related liver fibrosis.Methods A total of 228 patients with HBV infection who were admitted to The First Affiliated Hospital of Guangxi Medical University from June 2017 to August 2023 were enrolled.The transient elastography system FibroScan was used to determine liver stiffness measurement(LSM)for all patients,and according to the LSM value,they were divided into non-liver fibrosis group with 80 patients,mild liver fibrosis group with 83 patients,advanced liver fibrosis group with 30 patients,and liver cirrhosis group with 35 patients.ELISA was used to measure the serum level of ESPL1.The Kruskal-Wallis H test was used for comparison of the serum level of ESPL1 between the four groups;the Spearman correlation analysis was used to investigate the correlation between ESPL1 and LSM;the receiver operating characteristic(ROC)curve was used to analyze the value of serum ESPL1 in predicting the progression of liver fibrosis.Results The liver cirrhosis group had a significantly higher serum level of ESPL1 than the non-liver fibrosis group and the mild liver fibrosis group(both P<0.05),and the advanced liver fibrosis group and the mild liver fibrosis group had a significantly higher serum level of ESPL1 than the non-liver fibrosis group(both P<0.05).The correlation analysis showed that there was a positive correlation between serum ESPL1 and LSM in the patients with HBV infection and varying degrees of liver fibrosis(r=0.515,P<0.001).Serum ESPL1 had an area under the ROC curve(AUC)of 0.809 in predicting liver cirrhosis and an AUC of 0.638 in predicting advanced liver fibrosis,with a sensitivity of 87.5%and 100%,respectively,and a specificity of 59.7%and 31.3%,respectively.Conclusion There is a certain correlation between serum ESPL1 and HBV-related liver fibrosis,and higher serum ESPL1 may indicate a higher degree of liver fibrosis.Serum ESPL1 is expected to become one of the serum markers for assisting in the diagnosis of liver cirrhosis and an important clinical method for dynamically monitoring the progression of liver fibrosis in patients with HBV infection.

ObjectiveTo investigate the performance of fibrosis-4 （FIB-4） versus aspartate aminotransferase-to-platelet ratio index （APRI） in predicting advanced liver fibrosis and disease progression in patients with chronic HBV infection. MethodsA total of 497 patients with chronic HBV infection who underwent liver biopsy in The First Affiliated Hospital of Guangxi Medical University from February 2013 to December 2022 were enrolled， among whom 404 were enrolled in a retrospective study and 75 were enrolled in a prospective study. Related indicators were collected， including demographic features （sex and age）， biochemical indices （alanine aminotransferase ［ALT］ and aspartate aminotransferase ［AST］）， and platelet count， and FIB-4 and APRI were calculated. The Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups， and the Kruskal-Wallis H test was used for comparison between multiple groups； the chi-square test was used for comparison of categorical data between groups. The area under the ROC curve （AUC） was used to assess the ability of APRI and FIB-4 in evaluating liver fibrosis degree and disease progression in patients with chronic HBV infection. ResultsIn the retrospective analysis， compared with the FIB-4<2.67 group， the FIB-4≥2.67 group had a significantly higher proportion of the patients who were diagnosed with liver cirrhosis or hepatocellular carcinoma （66.19% vs 47.54%， χ²=12.75， P<0.001）. The medians of FIB-4 and APRI increased significantly with liver fibrosis degree from F0 to F4 （H=42.5 and 35.9， both P<0.001）. As for the fibrosis stage of F0-F4， the median of FIB-4 was significantly higher than that of APRI in the patients with the same fibrosis stage （H=59.71， P<0.001）. FIB-4 and APRI had a similar AUC for predicting stage F3 fibrosis （0.67 vs 0.65， Z=0.71， P=0.480）， while FIB-4 had a higher AUC for predicting stage F4 fibrosis than APRI （0.72 vs 0.64， Z=10.50， P<0.001）. In the prospective study cohort， FIB-4 and APRI showed an increasing trend over time in predicting disease progression （chronic hepatitis B to liver cirrhosis）， with an AUC of 0.718 （95% confidence interval ［CI］： 0.476‍ ‍—‍ ‍0.760） and 0.555 （95%CI： 0.408‍ ‍—‍ ‍0.703）， respectively， and FIB-4 had a significantly higher accuracy than APRI in predicting disease progression （χ²=12.44， P<0.001）. ConclusionFIB-4 and APRI can be used to evaluate advanced liver fibrosis （F3 and F4） and predict disease progression， and FIB-4 is superior to APRI in certain aspects.

Objective:To investigate the risk factors of diabetic kidney disease (DKD) in type 2 diabetes mellitus (T2DM) patients in plain-sand areas and loess hilly areas of Gansu province.Methods:A total of 1 599 T2DM patients who participated in chronic disease and risk factors monitoring and basic public health service management were selected by multi-stage stratified random sampling method in the sandy plain areas and loess hilly areas of Gansu province. Questionnaire survey, physical measurement and laboratory tests were performed. Multivariate binary logistic model was used to analyze the influencing factors.Results:The prevalence of DKD was 22.1% (174/787) among T2DM patients in the sandy plain areas and 19.1%(155/812) in the loess hilly area, respectively. Hypertension ( OR=3.022), hyperuricemia ( OR=2.114) and HbA1c≥7%( OR=2.231) were the risk factors for DKD in the plain-sand areas, and the risk of DKD increased with age. In the loess hilly areas, female sex ( OR=0.379) was the protective factor for DKD; while duration of disease≥10 years ( OR=2.476), hyperuricemia ( OR=1.907), HbA1c≥7% ( OR=1.927) were the risk factors for DKD; and the risk of DKD increased with the increase of age, and decreased with the increase of per capita monthly income. Conclusions:The prevalence of DKD and its influencing factors are different between sandy plain areas and loess hilly areas in Gansu province. The prevention and treatment of hypertension should be given more attention in sandy plain areas. In addition, the screening of DKD should be conducted among T2DM patients, particularly for those with old age, hyperuricemia and HbA1c≥7% in both areas of the province.

Objective To investigate the efficacy of entecavir (ETV) versus tenofovir disoproxil fumarate (TDF) and the treatment measures for poor response in previously untreated chronic hepatitis B (CHB) patients with high viral load. Methods A total of 165 CHB patients who received antiviral therapy and met the inclusion criteria in Department of Infectious Diseases, The First Affiliated Hospital of Guangxi Medical University, from June 2016 to July 2021 were enrolled. The patients enrolled had a baseline HBV DNA level of > 6lg copies/ml and were previously untreated CHB patients who had used ETV or TDF for 48 weeks, and quantitative real-time PCR was used to measure HBV DNA. Virologic response rate was calculated after 48 weeks of treatment; a logistic regression analysis was used to investigate the influencing factors for the response of HBV DNA < 500 copies/mL and HBV DNA < 100 copies /mL at 48 weeks; a stratified analysis was performed to compare the virologic response rate of HBV DNA < 500 copies /ml and HBV DNA < 100 copies/ml after 48 weeks between the patients with different ages, sexes, baseline HBV DNA levels, baseline alanine aminotransferase (ALT) levels, types of first-line medication, and HBeAg statuses. The Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups, the chi-square test or the Fisher's exact test was used for comparison of categorical data between two groups, and the binary logistic regression model was used for multivariate analysis. Results After 48 weeks of treatment, 85.5% (141/165) of the patients achieved an HBV DNA load of < 500 copies/mL, and 66.1% (109/165) of the patients achieved an HBV DNA load of < 100 copies /mL, with no significant difference in treatment outcome between the ETV group and the TDF group. The multivariate logistic regression analysis showed that sex( OR =2.793, 95% CI : 1.197-6.517), baseline HBV DNA( OR =0.369, 95% CI : 0.142-0.959), baseline ALT( OR =4.556, 95% CI : 1.770-11.732), and baseline HBeAg( OR =0.120, 95% CI : 0.033-0.429) were influencing factors for complete virologic response(all P < 0.05). For the patients with normal ALT (≤40 U/L) at baseline, 75.6% (34/45) achieved an HBV DNA load of < 500 copies/mL after 48 weeks of treatment, and 53.3% (24/45) achieved an HBV DNA load of < 100 copies/mL, with no significant difference in treatment outcome between the ETV group and the TDF group. For the patients with abnormal ALT (> 40 U/L) at baseline, 89.2% (107/120) achieved an HBV DNA load of < 500 copies/mL after 48 weeks of treatment, and the proportion of such patients in the TDF group was significantly higher than that in the ETV group (96.1% vs 84.1%, χ 2 =4.386, P =0.036); 70.8% (85/120) achieved an HBV DNA load of < 100 copies/mL, the proportion of such patients was no significant difference between the TDF group and the ETV group (78.4% vs 65.2%). The response of HBV DNA < 100 copies/ml of the normal baseline ALT group and the abnormal baseline ALT group, there were no significant differences between the patients aged≤30 years and aged > 30 years (77.8% vs 47.2%, 85.2% vs 66.7%). For the patients who did not achieve complete virologic response (HBV DNA ≥100 copies/mL) after 48 weeks of treatment, 87.9% (29/33) achieved complete virologic response after the original treatment regimen was prolonged for 48 weeks, and 100% (9/9) of the patients achieved complete virologic response after switching to or adding the first-line nucleos(t)ide analogues (NUCs) without cross-resistance sites with the original regimen for another 48 weeks. Conclusion The patients aged > 30 years should receive antiviral therapy as early as possible, regardless of viral load and ALT level, especially those with a family history of liver cirrhosis or hepatocellular carcinoma; the patients aged ≤30 years who have a normal ALT level and a high viral load should consider initiating antiviral therapy after providing informed consent. For the patients with poor response after 48 weeks of treatment, first-line NUCs without cross-resistance sites with the original regimen should be switched to or added in time.

Objective To investigate the epidemiological features and antiviral response of patients with genotype 6 chronic hepatitis C (CHC) in Guangxi, China. Methods A total of 97 patients with genotype 6 CHC who were admitted to The First Affiliated Hospital of Guangxi Medical University from December 2012 to December 2020 were enrolled, among whom 62 patients were given antiviral therapy. The 62 patients receiving antiviral therapy were divided into interferon group with 22 patients and direct-acting antiviral agent (DAA) group with 40 patients. Related data were collected, including general demographic data, HCV RNA, liver function, routine blood test results, and renal function. The chi-square test was used for comparison of categorical data between groups. Results Among the 97 patients, there were 69 male patients (71.1%) and 28 female patients (28.9%), with a mean age of 41.97±10.12 years, and the patients aged 30-40 years accounted for 47.4% (46/97). Of all 97 patients, 95 (97.9%) had genotype 6a, 1 had genotype 6e, and 1 had genotype 6xa. Among the 65 patients with a definite route of infection, 41 (63.1%) had intravenous drug use, 14 had medical-related operations, 9 had blood transfusion, and 4 had sexual contact as the route of infection. For the interferon group, the rapid virologic response (RVR) rate at week 4 was 81.8% (18/22), the rate of undetectable virus at the time of drug withdrawal (Epoint) was 86.4% (19/22), the rate of sustained virologic response at 12 weeks after drug withdrawal (SVR12) was 81.8%, and the rate of sustained virological response at 24 weeks after drug withdrawal (SVR24) was 81.8%; 1 patient in this group experienced recurrence. All 40 patients in the DAA group were previously untreated patients (33 patients without liver cirrhosis and 7 patients with compensated liver cirrhosis), with an overall RVR rate of 87.5%(35/40), an Epoint rate of 100%, and an SVR12 rate of 100%, and there was no treatment failure or recurrence. Although different DAA regimens had different RVR rates, they all had a SVR12 rate of 100%. The patients with compensated liver cirrhosis and other diseases had a SVR12 rate of 100%. Conclusion Intravenous drug addiction is the main route of infection for patients with genotype 6 CHC in Guangxi, and CHC is more common in men, with genotype 6a as the main subtype. DAA treatment has a higher virologic response rate than interferon treatment, with an SVR12 rate of 100%. There is no significant difference in SVR12 rate between the patients with compensated liver cirrhosis and those without liver cirrhosis.

Objective:To explore the efficacy of the proximal tibial lateral locking plate with rafting screws combined with Jail screws in the treatment of collapse fracture of the lateral tibial plateau.Methods:A retrospective case series study was performed on clinical data of 36 patients with collapse fracture of the lateral tibial plateau admitted to Suqian Hospital of Nanjing Drum Tower Hospital Group from January 2016 to January 2020, including 19 males and 17 females, aged 34-68 years [(48.6±5.8)years]. Schatzker classification was type II in 28 patients and type III in 8 patients. All patients were treated using the proximal tibial lateral locking plate with raft screws combined with Jail screws. The operation time, intraoperative blood loss and fracture healing were detected. The distance of articular surface collapse of the tibial plateau, posterior inclination angle (PSA) of the tibial plateau, tibial plateau varus angle (TPVA) and Rasmussen anatomical score were compared before operation and at day 2 and 1 year after operation. The Hospital for Special Surgery (HSS) score was used to evaluate knee function at day 2 and 1 year after operation. Complications were also recorded.Results:All patients were followed up for 12-32 months [(19.5±3.1)months]. The operation time was 56-82 minutes [(68.5±9.1)minutes]. The intraoperative blood loss was 40-100 ml [(75.6±10.2)ml]. The fracture was clinically healed by first-stage, with the healing time of 8 to 15 weeks [(12.5±1.3)weeks]. The distance of articular surface collapse of the tibial plateau was improved from (15.5±4.2)mm before operation to (0.7±0.3)mm at day 2 after operation and (1.0±0.2)mm at 1 year after operation (all P<0.01). The PSA was improved from (21.2±2.1)° before operation to (8.9±0.8)° at day 2 after operation and (9.2±0.6)° at 1 year after operation (all P<0.01). The TPA was improved from (100.2±3.7)° before operation to (88.9±1.8)° at day 2 after operation and (87.2±1.6)° at 1 year after operation (all P<0.05). The Rasmussen anatomical score changed from (7.8±1.8)points before operation to (17.1±0.9)points at day 2 after operation and (16.3±0.7)points at 1 year after operation (all P<0.01). There were no significant difference in the distance of articular surface collapse of the tibial plateau, PSA, TPVA and Rasmussen anatomical score at day 2 and 1 year after operation (all P>0.05). The HSS score was (92.8±3.2)points at 1 year after operation, significantly higher than (74.8±3.5) points at day 2 after operation ( P<0.01). Two patients sustained superficial wound infection after operation, which healed after debridement and dressing change. No deep infection occurred. Conclusion:For patients with collapse fracture of the lateral tibial plateau, the proximal tibial lateral locking plate with rafting screws combined with Jail screws can effectively prevent secondary collapse of the articular surface and obtain satisfactory anatomical reduction, good functional recovery and few postoperative complications.
