[Abstract]Objective:To explore the application effect and safety of ultrasound bone scalpel and high-speed turbine mobile phone in surgical procedures for patients with jaw cysts.Methods:A total of 100 patients with maxillary cysts who underwent curettage surgery in our hospital from January 2024 to June 2025 were selected for the study. The enrolled patients were randomly divided into a control group and an experimental group using the hidden envelope method, with 50 patients in each group. The conventional group used high-speed turbine mobile phones for bone removal during surgery, while the experimental group used ultrasonic bone knives for bone removal during surgery. The surgical conditions, postoperative pain and swelling, and incidence of complications during hospitalization were compared between the two groups of patients. Follow up for six months after surgery to compare the nerve damage and bone healing between the two groups of patients.Results:The intraoperative bleeding volume, postoperative 24-hour drainage volume, and bone cutting accuracy deviation of the experimental group were (30.59 ± 5.24) mL, (20.55 ± 5.28) mL, and (0.18 ± 0.05) mm, respectively, all lower than those of the control group [(40.19 ± 7.33) mL, (30.46 ± 6.45) mL, and (0.59 ± 0.12) mm] (t=7.534，8.407，22.301; P<0.05); The surgical time of the experimental group was similar to the control group (P>0.05). The VAS scores and swelling scores of the experimental group at 24, 48, and 72 hours after surgery were lower than the control group (t=4.403，3.354，12.986，4.610，2.911，14.888；; P<0.05). The incidence of complications during hospitalization in the experimental group was 4.00% (2/50) lower than the control group 18.00% (9/50) (x2=5.005; P<0.05).The NCV of the experimental group was higher than the control group at the1,3,6 months of follow-up, and TPD was lower than the control group (t=4.598，5.784，6.322，3.194，3.595，3.501; P<0.05). As of the end of follow-up, the osteogenic rate of the experimental group was (75.27 ± 8.14)% higher than the control group (68.18 ± 5.27)%. The bone defect area, wound healing time, and bone resorption were (55.29 ± 5.42)%, (3.22 ± 0.47) months, and (1.25 ± 0.36) mm, lower than the control group [(62.44 ± 7.51)%, (5.08 ± 1.33) months, and (2.49 ± 0.32) mm] (t=5.170，5.459，9.324，18.204; P<0.05).Conclusion:Compared with high-speed turbo phones, ultrasonic bone scalpel can reduce the risk of intraoperative bleeding in patients with jaw cysts and achieve precise bone removal. It can alleviate postoperative pain and swelling while greatly avoiding postoperative nerve damage, and has a positive impact on promoting bone healing in patients.

Objective To compare the efficacy and safety of remimazolam tosilate and propofol in painless ultrasonic gastroscopy. Methods In a randomized, single-blind controlled study, 60 patients undergoing ultrasonic gastroscopy were selected and divided into observation group (31 cases) and control group (29 cases). Observation group was anesthetized with remimazolam tosilate, while control group was anesthetized with propofol. Two groups' hemodynamic index, perioperative adverse events, changes of MOAA/S score, awakening and departure time were observed at different time points during anesthesia. Results The observation group had less changes on hemodynamics. The observation group had enough depth of sedation, while the control group had a deeper degree of sedation. The onset time of the two groups was similar and both awoke quickly and left, but the awakening time and leaving time in the observation group were slightly shorter. Adverse events in the control group were more than those in the observation group. Conclusions Remimazolam tosilate for painless ultrasonic gastroscopy had little effect on hemodynamics, which can generate enough depth of sedation, and make patients wake up quickly. In addition, the incidence of its adverse events was low, and the overall effectiveness and safety were superior to those of propofol.

Objective To comparatively analyze the effects of methotrexate (MTX) combined with uterine curettage under ultrasonic monitoring and MTX, uterine artery embolization (UAE) combined with uterine curettage in the treatment of cesarean scar pregnancy (CSP) within 7 weeks of menopause. Methods The clinical data of patients with type Ⅱ-Ⅲ CSP within 7 weeks of menopause who were admitted to the hospital from January 2016 to December 2017 were analyzed retrospectively. Another 69 cases treated with MTX combined with uterine curettage were selected as group A and 68 cases treated with MTX+UAE+uterine curettage were selected as group B.

The time of menstrual recovery, the recovery time of blood β-hCG and the disappearance time of scar pregnancy lesions were statistically analyzed. Results The two groups recovered well after operation, and there was no uncontrollable uterine bleeding. All fetal sac tissues were cleared. The intraoperative blood loss, hysterectomy rate, incidence rates of fever, postoperative abdominopelvic pain and liver function injury in group A were less/lower than those in group B, The rate of blood β-hCG decreasing more than 50% on the 1st day after operation, the success rate of treatment and hospitalization time of groups A were higher/longer than those of group B, while the time of menstrual recovery, recovery time of blood β-hCG and the disappearance time of scar pregnancy lesions was shorter than that of group B(P<0.05). Conclusion MTX combined with uterine curettage may avoid complications and side effects of UAE in patients with type Ⅱ-Ⅲ CSP within 7 weeks of menopause, without increasing the risk of bleeding.

Objective To study the clinical value of ultrasonic quantitative detection in blood flow and middle cerebral artery blood flow in fetal distress. Methods 150 hospitalized pregnant women were included in the study, including fetal distress group (n=72) and normal control group (n=78). Color Doppler ultrasonography was performed on all pregnant women. The maximal systolic blood flow velocity and end diastolic blood flow velocity ratio(S/D), resistance index (RI) and pulsatility index (PI) of the umbilical artery (UA) and the middle cerebral artery (MCA) were recorded. The application value of ultrasonic UA and MCA blood flow detection were analyzed by the receiver operating curve (ROC).

The S/D, RI and PI of MCA in fetal distress were significantly lower than those in normal control group(P＜0.05). The ROC of UA and MCA showed that S/D, RI and PI of sensitivity were[0.986,0.958,0.944 vs 0.897,0.924,0.892],the specificity were[0.614, 0.625,0.534 vs 0.712,0.657,0.684]. Conclusion The prenatal ultrasound combined detection UA and MCA blood flow parameters are helpful for screening fetal distress, improving diagnostic accuracy and guiding the clinical.

Objective To construct a gemcitabine-resistant variant of the breast cancer cell line (4T1/Gem) and establish a nude mouse model of breast cancer with hepatic metastatic. Methods A gemcitabine-resistant variant of the breast cancer 4T1 cell line was induced by gradually increasing the concentration of gemcitabine; this variant is referred to in this study as 4T1/Gem. The proliferation suppression rates of 4T1 and 4T1/Gem cells were determined by using the CCK-8 essay to evaluate the drug resistance indices of the cell lines. Western blot analysis was used to detect P-gp protein expression. Under ultrasonography, a 4T1/Gem cell suspension was injected into nude mice to induce liver tumors. H&E staining was used to observe tumor pathology, and immunohistochemistry was used to detect the expression of ER, PR, HER-2, Ki-67, and P-gp. Results After 14 months of induction, a 4T1/Gem cell line is established successfully. The cell line can grow stably in culture liquid containing 40 μg/ml gemcitabine. The drug resistance index of 4T1/Gem is 788.547. Compared with the 4T1 cell line, the 4T1/Gem cell line can upregulate P-gp protein expression and successfully establish a nude mouse model of breast cancer with hepatic metastatic. ER, PR, and HER-2 proteins exhibit negative expression in the tumor tissue. The positive expression of P-gp and 10% of Ki-67 proteins is also observed. Conclusion This study successfully constructs a gemcitabine-resistant variant of the breast cancer cell line (4T1/Gem)and establishes a nude mouse model of breast cancer with hepatic metastatic, thereby providing an experimental basis for developing and treating a drug-resistant variant of breast cancer.
