Objective To investigate the expression and clinical significance of heat shock protein family A member 5(HSPA5)and apolipoprotein B mRNA editing enzyme catalytic polypeptide-like protein 3B(APO-BEC3B)in high-risk human papillomavirus(HR-HPV)positive cervical cancer patients.Methods A total of 86 patients with HR-HPV positive cervical cancer tissues diagnosed and treated in Zhuhai Integrated Tradi-tional Chinese and Western Medicine Hospital from March 2019 to March 2021 were retrospectively collected as the case group,50 cases of HR-HPV negative cervical cancer patients tissues diagnosed and treated during the same period were selected as the case control group,and 50 cases of normal cervical tissues from patients undergoing total hysterectomy were selected as the benign control group during the same period.The protein expressions of HSPA5 and APOBEC3B were analyzed by immunohistochemistry.The expressions of HSPA5 mRNA and APOBEC3B mRNA were detected by real-time fluorescence quantitative PCR.Kaplan-Meier sur-vival curve was used for survival analysis,and Cox proportional hazards regression model was used to analyze the prognostic factors of HR-HPV positive cervical cancer patients.Results The expressions of HSPA5 mR-NA and APOBEC3B mRNA in the case group were higher than that in the case control group and benign con-trol group,and the difference was statistically significant(P<0.05).The positive expressions of HSPA5 pro-tein and APOBEC3B protein in the case group were higher than those in the case control group and the benign control group,and the difference was statistically significant(P<0.05).Compared with FIGO stage Ⅰ A-Ⅰ B and without lymph node metastasis,the positive rates of HSPA5 and APOBEC3B proteins in HR-HPV positive cancer tissues with FIGO stage Ⅱ A and lymph node metastasis were higher,and the difference was statistically significant(P<0.05).The 3-year survival rate of HSPA5 protein positive group was 68.52%(37/54),which was lower than that of HSPA5 protein negative group(87.50%,28/32),and the difference was statistically significant(Log Rank x2=4.103,P=0.043).The 3-year survival rate of APOBEC3B protein positive group was 67.31%(35/52),which was lower than that of APOBEC3B protein negative group(88.24%,30/34),and the difference was statistically significant(Log Rank x2=5.241,P=0.022).FIGO stage(HR=1.570,95%CI:1.038-2.374),lymph node metastasis(HR=1.754,95%CI:1.109-2.775)and HSPA5 protein(HR=1.616,95%CI:1.154-2.265)and APOBEC3B protein(HR=1.449,95%CI:1.095-1.918)in cancer tissues were independent factors affecting the prognosis of HR-HPV positive cervical cancer(P<0.05).Conclusion HSPA5 and APOBEC3B mRNA and protein levels are significantly increased in HR-HPV positive cervical cancer.The protein expression of HSPA5 and APOBEC3B is related to the pro-gression and prognosis of patients with HR-HPV positive cervical cancer,which is a new prognostic marker for evaluating the prognosis of HR-HPV positive cervical cancer.

AIM: To compare the clinical efficacy, vault, and rotational stability of horizontal, oblique, and vertical implantation of Toric implantable collamer lens(TICL).METHODS: Retrospective cohort study. A total of 92 cases(120 eyes)who underwent TICL implantation from July 2018 to March 2022 and had regular follow-up for at least 1 a postoperatively(1 d, 1 wk, 1, 3, 6 mo, and 1 a)at Wuhan Bright Eye Hospital were collected. The patients were divided into three groups, with 34 cases(45 eyes)in horizontal implantation group, 25 cases(29 eyes)in oblique implantation group(29 cases), and 33 cases(46 eyes)in vertical implantation group. Uncorrected distance visual acuity(UDVA), corrected distance visual acuity(CDVA), diopters, vault, and rotation angle(deviation of the actual axis of TICL from the expected axis).RESULTS: All surgeries were uneventful, and there were no complications such as infection, secondary glaucoma, or cataract opacity. Safety and efficacy of the surgery: the CDVA of the three groups of patients was better than or equal to the preoperative CDVA at 1 a postoperatively, and there was no statistically significant differences in postoperative UDVA and CDVA of the three groups(P>0.05). The safety index at 1a postoperatively was 1.34±0.21, 1.34±0.17, and 1.31±0.18 for the horizontal, oblique, and vertical groups, respectively. The efficacy index was 1.26±0.21, 1.33±0.18, and 1.27±0.16 for the three groups, respectively, both with no statistically significant differences(P>0.05). Vault: there was a significant difference in postoperative vault among the three groups(P=0.003), with the vertical group having the lowest vault, followed by the horizontal group and the oblique group. The vaults at different follow-up time points within each group showed significant differences(P<0.001), and all decreased over time. Residual astigmatism: there was no significant difference in residual astigmatism among the three groups(P=0.130), but there were differences at different follow-up time points within each group(P<0.001). Rotation angle: no significant differences in rotation angle were observed among the three groups(P=0.135), but there were differences at different follow-up time points within each group(P<0.001).CONCLUSION: The implantation of TICL in different orientations has good safety and efficacy, the postoperative rotational stability is good, and the appropriate angle can be selected to implant TICL according to the clinical situation.

Objective To discuss the therapeutic effect of uterine arterial embolization in treating adenomyosis.Methods Uterine arterial embolization was performed in 80 patients with adenomyosis.The patients were followed up for 3,6,12 and 24 months after the operation.After the treatment the degree of dysmenorrhea,the menstrual flow and the uterine volume were observed and were compared with those before the treatment.Results After uterine arterial embolization the clinical symptoms were relieved in all 80 patients.The menstrual flow was markedly decreased,the anemia was obviously improved and the uterine volume was significantly reduced,while the ovary functioning was not apparently affected.The symptom of dysmenorrhea completely disappeared one month after the therapy in 76 cases and four months after the therapy in the remaining 4 cases.Conclusion Uterine arterial embolization is a mini-invasive and safe therapy with remarkable therapeutic results and few side-effects.Therefore,this treatment can significantly improve the patient's living quality.
