Objective:To explore the effect of levonorgestrel-releasing intrauterine system (LNG-IUS) placed in the uterine cavity after transcervical preparation for the treatment of adenomyosis (AM).Methods:A retrospective study analyzed 219 cases of AM patients treated at Department of Obstetrics and Gynaecology, the Second Hospital of Hebei Medical University from March 2022 to February 2023. Among them, 112 cases were treated with LNG-IUS after hysteroscopy due to abnormal uterine bleeding or abnormal uterine echo suggested by gynecological ultrasound, and were recorded as the hysteroscopy+LNG-IUS group; 107 cases without the above manifestations were treated with LNG-IUS alone, and were recorded as the LNG-IUS group. The two groups were observed for dysmenorrhea severity, menstrual volume, endometrial thickness, anemia, serum CA125 levels, uterine volume, and adverse reactions such as abnormal vaginal bleeding and intrauterine contraceptive device displacement or shedding before and 1, 3, 6, and 12 months after treatment.Results:1) Postoperative pathology of hysteroscopy+LNG-IUS group after hysteroscopy included endometrial polyps [39.3% (44/112)], proliferative endometrium [16.1% (18/112)], uterine leiomyoma [11.6% (13/112)], secretory endometrium [8.9% (10/112)], irregular endometrial hyperplasia [6.2% (7/112)], simple hyperplasia [5.4% (6/112)], AM lesions [4.5% (5/112)], and others [8.0% (9/112)]. 2) The degree of dysmenorrhea and menstrual volume, as well as other indicators, improved after treatment in both groups (all P<0.001). 3) When comparing the two groups, the degree of dysmenorrhea, menstrual volume, endometrial thickness, anemia, and serum CA125 at 1, 3, 6, and 12 months of treatment, the hysteroscopy+LNG-IUS group was significantly better than those in the LNG-IUS group (all P<0.05), the difference of uterine volume at 12 months of treatment between the hysteroscopy+LNG-IUS group [(109.76±32.90) cm 3] and the LNG-IUS group [(120.84±31.30) cm 3] was statistically significant ( P=0.011). 4) The cumulative incidence of adverse reactions of the two groups was statistically significant ( P=0.001) between the hysteroscopy+LNG-IUS group [24.1% (27/112)] and the LNG-IUS group [52.3% (56/107), P=0.001]. The hysteroscopy+LNG-IUS group had lower rates of vaginal irregular bleeding [8.0% (9/112)] and ring displacement or shedding [3.6% (4/112)] than those in the LNG-IUS group [23.4% (25/107), P=0.002; 11.2% (12/107), P=0.030]. Conclusion:After treatment with hysteroscopy, the placement of LNG-IUS and the simple intrauterine placement of LNG-IUS both significantly improve the severity of dysmenorrhea, endometrial thickness, anemia, menstrual volume, CA125, and uterine volume. The treatment effect of the LNG-IUS group after hysteroscopy is better and adverse reactions are milder, and it is expected to become the preferred option for the long-term management of conservative treatment of AM.

Objective To study the correlation between the level of CaMKIV and essential hypertension (EH) in Shihezi community. Methods One hundred and forty-six patients with EH and 142 with normal blood pressure are enrolled from 15 communities in shihezi. We collected the clinical data, including blood pressure, body mass index, waist circumference, blood lipids. The serum level of CaMKIV was detected using an enzyme linked immunosorbent assay. Results The serum level of CaMKIV in the EH group was significantly lower than that in the normal blood pressure group (P < 0.05). The serum CaMKIV was negatively correlated with systolic BP and diastolic BP (r = -0.304, -0.452, all P < 0.05), with more obvious correlation with patients whose diastolic blood pressure was over 100 mmHg (r = -0.571, P < 0.05). Conclusions The serum level of CaMKIV is negatively correlated with EH, which is an independent factor of EH.

Objective To investigate the correlation of cyclophilin A (CyPA) level in patients with essential hyperten?sion(EH)in Xinjiang Xibo and Mongolia populations and to investigate its clinical significance. Methods EH patients (n=76) and healthy control subjects (n=62) were selected from Xinjiang Xibo populations. On the other hand, EH patients (n=66)and healthy control subjects (n=57) were selected from Xinjiang Mongolia populations. Serum cyclophilin A was measured using enzyme-linked immunosorbent assay(ELISA). Parameters such as age, body mass index(BMI), waist, waist hip ratio, blood pressure were measured in each group. The correlation of cyclophilin A with each parameter was analyzed. Results The levels of serum cyclophilin A in EH patients in Xinjiang Xibo and Xinjiang Mongolia populations were significantly high?er than those in their corresponding healthy control groups(P<0.05). Serum cyclophilin A in patients with essential hyperten?sion(EH)in Xinjiang Mongolia population was signifantly higher than that in EH patients from Xinjiang Xibo population (P<0.05). There was a positive correlation between serum cyclophilin A level and occurance of EH in both Xinjiang Xibo and Xinjiang Mongolia populations. Conclusion The serum cyclophilin A is significant higher in EH patients in both Xinji?ang Xibo and Xinjiang Mongolia populations so it is positively correlated with occurance of EH (P<0.05). Cyclophilin A lev?el is a risk factor of essential hypertension in both Xinjiang Xibo and Xinjiang Mongolia populations.
