Objective:To explore the effectiveness and application value of focused ultrasound ablation surgery (FUAS) combined with hysteroscopic surgery in treating solitary type Ⅱ submucosal uterine fibroids with maximum diameter >5 cm.Methods:Clinical data of 35 patients with a single type Ⅱ submucosal uterine fibroid with maximum diameter greater than 5 cm who underwent FUAS combined with hysteroscopic surgery at Qingdao Women and Children′s Hospital from June 2020 to December 2023 were collected. The clinical characteristics, treatments and treatment outcomes were retrospectively analyzed.Results:(1) Clinical characteristics: the mean age of the 35 patients was (36.7±6.6) years, with a median maximum diameter of fibroids of 56 mm (range: 51-80 mm). All patients presented with symptoms of menorrhagia, median menstrual bleeding score was 5 points (ranged from 3 to 5 points), and 34 cases (97.1%, 34/35) had concomitant anemia, the mean hemoglobin was (83.1±13.8) g/L of 35 patients. (2) Treatments: all 35 patients underwent FUAS treatment initially, with a lesion ablation rate ranging from 69.7% to 97.9% (median:90.7%), and no complications occurred. After FUAS treatment, the volume of fibroids decreased in all patients, with a volume reduction rate ranging from 30.57% to 87.22% (median:76.03%). Hysteroscopic surgery was performed 3-14 months (median: 5 months) after FUAS to remove the necrotic fibroid tissue, achieving a 100.0% (35/35) fibroid resection rate. Only 1 patient developed complications of hyperhyderation syndrome during hysteroscopic surgery, and no complications occurred in the remaining patients. (3) Evaluation of efficacy: after FUAS pretreatment, the maximum diameter of fibroids in the 35 patients decreased significantly ( Z=-5.171, P<0.001), as did the volume of fibroids ( Z=-5.159, P<0.001). The hemoglobin level increased significantly compared to the level before FUAS in all cases ( t=-8.657, P<0.001), and median menstrual bleeding score decreased to 2 points (range: 1-3 points), significantly lower than original level ( Z=-5.292, P<0.001). At the 3-month follow-up after hysteroscopic surgery, all patients were free of anemia symptoms, with menstrual bleeding scores totally decreased to 1 point, significantly lower than that before hysteroscopic surgery ( Z=-4.786, P<0.001); hemoglobin level [(118.7±5.6) g/L] significantly increased compared to that before hysteroscopic surgery ( t=-9.258, P<0.001). All patients underwent gynecological transvaginal ultrasound re-examination, which did not reveal any residual fibroids. Conclusion:FUAS combined with hysteroscopic surgery is effective in treating solitary type Ⅱ submucosal uterine fibroids with maximum diameter >5 cm, providing a new treatment option for patients.

Objective:To explore the effectiveness and safety of focused ultrasound ablation surgery (FUAS) for abdominal wall endometriosis.Methods:From November 2019 to October 2022, a total of 34 patients with abdominal wall endometriosis who underwent FUAS were collected, and their clinical features, imaging features, intraoperative treatment and side effects after treatment were analyzed retrospectively, and the improvement of symptoms and re-intervention were followed up.Results:(1) Characteristics of clinical data: the average age of 34 patients with abdominal wall endometriosis was (32.8±3.8) years old. The largest diameter of the lesion was 48 mm, and the median lesion diameter was 24 mm. Thirty cases (88%, 30/34) had moderate to severe periodic pain in abdominal incision before FUAS. All patients were diagnosed by preoperative magnetic resonance imaging, including 19 cases (56%, 19/34) of superficial type, 8 cases (24%, 8/34) of intermediate type and 7 cases (21%, 7/34) of deep type. (2) FUAS treatment parameters: ablation was completed with average operation time of (64±18) minutes, average sonication time was (385±108) s, (103±11) W of average power, (38 819±16 309) J of average total energy, the average treatment area volume of (3.11±1.42) cm 3, and (377.79±106.34) s/h of average treatment intensity. (3) Efficiency: the pain of patients after FUAS was significantly relieved, and the pain scores of patients after 1 month, 3 months, 6 months and 1 year after FUAS were significantly decreased ( Z=-4.66, -5.13, -5.11 and -4.91, all P<0.01). One year after FUAS, the near relief and effective pain relief rate was 74% (25/34), and the clinical effective rate was 85% (29/34). Five patients recurred after one year, including 3 patients who underwent abdominal wall endometriosis lesion resection and 2 patients who received drug treatment. One month after FUAS, the size of the lesion did not change significantly compared with that before FUAS ( P>0.05), and the size of the lesion decreased significantly after FUAS at 3 months, 6 months and 1 year ( Z=-2.15, -2.67 and -3.41, all P<0.05). It has no difference in pain relief among different types ( P>0.05), but has significant difference in focus reduction among three types ( P<0.01). (4) Safety: there were 34 cases (100%, 34/34) of skin burning sensation, 19 cases (56%, 19/34) of pain in the treatment area and 2 cases (6%, 2/34) of hematuria. All patients got better after corresponding treatments. Conclusion:FUAS is safe and effective for the treatment of abdominal wall endometriosis, which has clinical application value.

Objective:To perform cross-cultural adaption of the KING′s Parkinson′s Disease Pain Scale (KPPS), explore its reliability and validity in Chinese Parkinson′s disease (PD) patients, and to create the new version of the pain scale which adapts to the Chinese PD patients.Methods:This study enrolled 225 patients, including 121 men and 104 women who were selected from the Outpatient Center of Movement Disorders Clinic of the Second Affiliated Hospital of Soochow University from July 2018 to July 2020. All patients completed the evaluation of the Chinese Version of KPPS (KPPS-CV). According to the preliminary evaluation results, the expert group modified KPPS-CV after discussion, and developed a Modified KPPS-CV (MKPPS-CV). These patients then completed the MKPPS-CV evaluation during the 3-month follow-up. Cross-cultural adaptation was performed according to published international guidelines that include translation, back-translation, expert review, and pretesting. The following psychometric properties were evaluated: basic item analysis; floor and ceiling effects; construct validity; content validity; criterion validity (Spearman′s rho between the KPPS-CV and Numeric Rating Scale); internal consistency reliability (Cronbach′s alpha); test-retest reliability (intra-class correlation coefficient, ICC).Results:In item analysis, 50% of the items had poor discrimination (critical ratio<3.0), and floor effect was found in all domains (proportion of 0 point>15%). The items were reclassified after exploratory factor analysis. The content validity of item 3, item 10 and item 11 was low (item-level content validity index<0.78). Criterion validity showed the highest correlations (Spearman′s rho>0.88) between the KPPS-CV and Numeric Rating Scale. While overall scale reliability was minimally acceptable at 0.46, which showed a poor reliability of this scale. Test-retest reliability was excellent for each item (Spearman's rho>0.85). The Cronbach′s alpha of MKPPS-CV (0.76) was higher than that of KPPS-CV (0.46). It showed a great improvement after the modifying.Conclusions:When using scales that are not developed for local populations, differences in culture and clinical practices should be taken into account. MKPPS-CV is an acceptable, valid measure to evaluate pain in Chinese PD patients, which is more suitable for Chinese people.

Background. Transesophageal echocardiography(TEE) is an advanced technique. The purpose of this article is to discuss the complication and safety of the TEE.Method. Fifteen hundred and fifty-two patients with heart disease were examined with monoplane, biplane and omniplane TEE probe(including male 727, female 825;9～76 years old). During the same period, 113 307 precordial echocardiographic examinations were performed in our laboratory. The ratio between TEE and transthoracic Echo examines was 1:73.Result.All different kinds of complication were occurred during TEE examination, including vomiting, minor mucus bleeding, laryngospasm, mandibular dislocation, angina pectoris, arrhythmia, even ventricular fibrillation and death. The article suggested that there were five steps must be improved during TEE examination including instrument and patients preparation, local anesthesia, manipulation technique and TEE probes pattern.Conclusion. Although TEE is a semiinvasive technique and can cause some kinds of complication, it is a safe technique if the five steps are improved.
