ObjectiveTo investigate the clinical effect of EaLeSu on cervical intraepithelial neoplasia(CIN Ⅱ~Ⅲ)patients with HPV infection treated with loop electrosurgical excision procedure(LEEP). Methods 165 cases of CIN Ⅱ~Ⅲpatients with HPV infection who underwent LEEP operation were randomly divided into observation group(n=83)and control group(n=82). In the observation group,patients were given a piece of EaLeSu in cervical wound at once in postoperative and two vaginal EaLeSu per day from the first postoperative day for eight consecutive days. The patients in the control group were treated with routine debridement and wound dressing with iodine. We observed the vaginal drainage times within 4 weeks after operative,bleeding rate,cervical wound repair,and cervical HPV DNA infection after 6 months. Results There were significant differences in the bleeding rate,vaginal drainage time,cervical wound repair and HPV DNA infection between the two groups(P < 0.05). Conclusion EaLeSu showed a definite effect on cervical intraepithelial neoplasia(CIN Ⅱ~Ⅲ)patients with HPV infection treated with LEEP.

The role of multidisciplinary collaborative diagnosis and treatment (MDT) in improving the prognosis of colorectal cancer, lung cancer, breast cancer and other tumors has been proven, but the research of oral cancer MDT is still in the exploratory stage and has not formed a complete conceptual system and operating mode. Oral squamous cell carcinoma (OSCC) is one of the main malignant tumors of the head and neck, with a 5-year survival rate of less than 50%. This article mainly elaborates on the difficulties of oral cancer treatment, the advantages of MDT, and the progress of oral cancer MDT.

Background: MicroRNA (miRNA) plays a crucial role in neuropathic pain (NP) by targeting mRNAs. This study aims to analyze the regulatory function and mechanism of miR-382-5p/dual specificity phosphatase-1 (DUSP1) axis in NP. Methods: We utilized rats with chronic constriction injury (CCI) of the sciatic nerve as the NP model. The levels of miR-382-5p and DUSP1 were reduced by intrathecal injection of lentiviral interference vectors targeting miR-382-5p and DUSP1. The mRNA levels of miR-382-5p and DUSP1 in the dorsal root ganglions (DRGs) were measured by RT-qPCR assay. The pain behavior was evaluated by mechanical nociceptive sensitivity and thermal nociceptive sensitivity. The expression levels of interleukin-6 (IL)-6, IL-1β, and tumor necrosis factor-α in the DRGs were analyzed by ELISA assay. The targeting relationship between miR-382-5p and DUSP1 was verified by DLR assay and RIP assay. Results: Compared to the Sham group, the CCI rats exhibited higher levels of miR-382-5p and lower levels of DUSP1. Overexpression of miR-382-5p significantly decreased DUSP1 levels. Reducing miR-382-5p levels can lower the mechanical nociceptive sensitivity and thermal nociceptive sensitivity of CCI rats and inhibit the over-activation of pro-inflammatory factors. Reduced miR-382-5p levels decreased NP in CCI rats. DUSP1 is the target of miR-382-5p, and down-regulation of DUSP1 reverses the inhibitory effect of reduced miR-382-5p levels on NP. Conclusions Down-regulation of miR-382-5p inhibits the over-activation of pro-inflammatory factors by targeting and regulating the expression of DUPS1, thereby alleviating NP.

To explore the prognostic value of heat shock protein-90α (HSP-90α) plasma levels on breast cancer and non-breast malignant tumors, monitoring the response of chemotherapy, and the predictive value of cancer recurrence and metastasis. Methods: A total of 615 female patients were enrolled between June 2016 and September 2016 in Cancer Hospital, Chinese Academy of Medical Sciences, who were divided into the examination (n=389) and control (n=216) groups. The former group consisted of static (n=289) and dynamic (n=110) groups, which were analyzed by stages, histological and molecular type, and so on. The latter group in-cluded healthy people (n=103), and those with breast benign tumors (n=51) and non-breast malignant tumors (n=62). In all the plasma samples, HSP-90α was detected using a double-antibody enzyme-linked immunosorbent assay. The receiving-operating characteristic curve was used to analyze the effectiveness of plasma HSP-90α in the diagnosis of breast cancer. Wilcoxon＇s rank test and the Kruskal-Wallis test were used to analyze the association between clinical characteristics and levels of plasma HSP-90α. Results: The levels of plasma HSP-90α were significantly higher in patients with breast cancer than in healthy controls (P<0.001). When the cut-off value was set as 59.7 ng/mL for the diagnosis of breast cancer and 43.22 ng/mL for disease recurrence, the areas under the curve were 0.834 and 0.877, sensitivities were 90.3% and 95.7%, and specificities were 78.6% and 74.5%, respectively. The levels of plasma HSP-90α sig-nificantly decreased after achieving a response to neoadjuvant chemotherapy or surgery (P<0.05). Conclusions: Plasma HSP-90α has good clinical value in the diagnosis and monitoring of response and recurrence in breast cancer.

Objective:Anterior cruciate ligament injury is the most common type of knee joint ligament injury.Anterior cruciate ligament reconstruction has a high failure rate,with bone tunnel abnormalities as the most significant factor in these failures.Digital orthopedic technology can effectively develop implementation plans for the revision,thus increasing the success rate.This study aims to develop a surgical plan for anterior cruciate ligament revision by employing multiplanar reconstruction(MPR)for measuring bone tunnel position and diameter,and simulating bone tunnel creation via 3D printing preoperatively. Methods:A total of 12 patients who underwent anterior cruciate ligament revision at the Third Xiangya Hospital of Central South University between 2014 and 2021 were retrospectively studied.The data included patient demographics,preoperative formulated knee joint 3D printing models,and preoperative knee CT scans.The study measured the bone tunnel's diameter and position to guide the establishment of revision bone tunnels during surgery,reassessed the postoperative bone tunnels,and evaluated knee joint functional scores[including International Knee Documentation Committee Knee Evaluation Form(IKDC)score,Lysholm score,and Tegner exercise level score]. Results:Preoperative measurements revealed suboptimal femoral tunnels positions in 4 patients and tibial tunnels positions in 2 patients.MPR and 3D printing technology were used to guide the establishment of a new bone canal during surgery,and postoperative measurements were satisfactory for all patients.Preoperative measurements demonstrated the interclass correlation coefficient for femoral tunnels and tibial tunnels diameters were 0.843(P<0.05)and 0.889(P<0.001),respectively.Meanwhile,the intraclass correlation coefficient were 0.811(P<0.05)and 0.784(P<0.05),respectively.The intraoperative diameter of femoral and tibial tunnels showed excellent correlation with postoperative CT measurements,with intraclass correlation coefficient values of 0.995(P<0.001)and 0.987(P<0.001),respectively.All bone tunnel positions were within the normal range.At the final follow-up,knee joint function scores in all 12 patients improved significantly compared to pre-surgery(P<0.001),and the reoperation rate was zero. Conclusion:MPR and 3D printing technology can accurately measure the parameters of reconstructed anterior cruciate ligament bone tunnels.Personalized revision plans for patients with reconstruction failure enhances the success rate of revision surgery and improves patient prognosis.

【Objective】 To study the risk factors of blood donors confirmed to be positive for syphilis, so as to avoid highrisk groups, guide the recruitment of blood donors and improve blood safety. 【Methods】 From September 2021 to August 2022, 44 514 blood samples were screened using two enzyme-linked immunosorbent reagents for syphilis, and the reactive samples were confirmed by TPPA. Blood collection time, blood collection location, blood donation numbers, gender, age, marital status and educational level of blood donors were taken as the prediction risk factors, and factors with statistically significant differences by univariate Logistic regression analysis were further analyzed using multivariate factor Logistic regression analysis to determine the final independent risk factors. 【Results】 A total of 121 syphilis antibody reactive samples were detected by enzyme-linked immunosorbent assay, and 64 were confirmed positive by TPPA. Excluding those with incomplete information, a total of 44 505 blood donors were included in the analysis. Logistic regression analysis showed that there were statistically significant differences in blood collection location, blood donation numbers, age and education level. 【Conclusion】 Based on the analysis results of risk factors of syphilis positive blood donors in Wuhu, it is necessary to strengthen the consultation of blood donors in blood donation sites. The high-risk groups are first-time blood donors over 50 years old, with education level of junior high school or below.
