Objective To observe the relationship between morphological and hemodynamic changes of female internal genital organs in the patients with hypomenorrhea with transvaginal color Doppler ultrasound (TVCDS). Methods Thirty female patients with hypomenorrhea of unknown origin were studied, and 30 healthy women of eumenorrhea aged 20 to 40 years were selected as control group. The size and shape of uterus, ovaries, and the thickness of endometria of uterus were observed with TVCDS in follicular phase, ovulation phase, luteal phase and luteal atrophy phase, respectively. Hemodynamic parameters of ovarian artery, uterus artery and their branches were measured. At the same time, hormones of female were examined in 30 patients in follicular phase, ovulation phase and luteal atrophy phase, respectively. Results ①No difference of the size of uterus and ovaries, the thickness of endometria and the amount of egg follicles was found between two groups (P＞0.05). ②Compared with that in the control group, type C of endometria increased in hypomenorrhea group (P＜0.05). ③RI, PI and S/D of spiral arteries in hypomenorrhea group were higher than those in control group, but no significance in these parameters of uterine arteries, arcuate arteries and radiate arteries was found. RI of uterine arteries, arcuate arteries and radiate arteries decreased successively. ④RI, PI and S/D of ovarian arteries in hypomenorrhea group was higher than those in control group in ovulation phase (P＜0.05). Conclusion Reduction in blood supply of ovary and endometria may be the causes of hypomenorrhea with unknown origin. TVCDS can be used as a conventional examination method for these patients.

Objective: To investigate the current status of prevention and treatment of venous thromboembolism (VTE) after thoracic surgery in China. Method: Chinese thoracic surgeons were investigated by the online questionnaire which was based on the Chinese version of International VTE questionnaire added with 6 extra questions with Chinese characteristics. Results: A total of 1 150 valid questionnaires were retrieved, accounting for about 20% of all the Chinese thoracic surgeons. The surgeons participating in this survey came from all over the country, most of whom were experienced professionals with high academic titles.For lung cancer patients, 66.96% (770/1 150) of the surgeons suggested that VTE prophylaxis should start 1 day after lung cancer resection, and 64.61% (743/1 150) of the surgeons suggested extending after discharge. For esophagestomy patients, and 48.35% (514/1 063) of the surgeons suggested that there was no need for patients to extend VTE prophylaxis after discharge. More than half of the surgeons participating in this survey made decision of the method and duration of VTE prophylaxis after lung cancer resection (53.91% (620/1 150)) or esophagectomy (52.49% (558/1 063)) depending on the clinical experience.Low molecular weight heparin was the common choice of most surgeons in VTE prophylaxis. More than half of the surgeons thought that previous history of VTE, advanced age, complicated with thrombophilia, obesity (body mass index>30 kg/m²), duration of surgery longer than 6 hours and family history of VTE were key risk factors of the occurrence of postoperative VTE. Conclusions The results of this survey are highly credible and are a good reflection of the current status of VTE prevention and treatment after thoracic surgery in China. This survey will play an important role in promoting VTE prevention and treatment in Chinese thoracic surgery department, it will also provide data support for government setting new policies, hospital construction of VTE prevention and control as well as raising physicians′ awareness.

Objective To evaluate the function of auditory nerve and brainstem in children with Bell's palsy by using brainstem auditory evoked potential ( BAEP) . Methods A retrospective study was car-ried in total of 69 patients with Bell's palsy admitted in the pediatric department of Shengjing Hospital of China Medical University from January 2017 to January 2018. There were 33 males and 36 females,aged 1 to 12 years old. Sixty healthy children served as control group. BAEP were determined in 69 patients and 60 healthy subjects. EEG and CT or MRI of brain were performed to exclud tumor,intracranial infection and so on. The patients in the case group were divided into 2 groups:1-3 years old group (38 cases) and 4-12 years old group (31 cases). Sixty healthy children were also divided into 2 groups:1-3 years old group (30 cases) and 4-12 years old group (30 cases). Results The hearing threshold was normal in the children of the control group. There was no significant difference not only in potential latency but also internal potential latency of BAEP between right and left ear. The abnormal rate of BAEP was 39. 1％ ( 27/69 ) in case groups,19 cases of them recovered(70. 4％,19/27) after 2 weeks of clinical treatment. Another 8 patients re-covered after 2 months. The abnormality rate of EEG was 5. 8％ (4/69),and the abnormality rate of CT or MRI in head was 14. 5％ (10/69). Both were nonspecific changes. In the two groups,Ⅰ-Ⅲinternal potential latency was significantly shortened ( P <0. 05 ) , and Ⅲ-Ⅴinternal potential latency was significantly pro-longed (P<0. 05)respectively,between the normal side and abnormal side. There were significant differences in the Ⅲ potential latency(P<0. 05),Ⅰ-Ⅲinternal potential latency (P<0. 01),and Ⅲ-Ⅴ internal poten-tial latency ( P <0. 01 ) respectively, between pretherapy and post-treatment. Conclusion Bell's palsy of children could cause abnormal of auditory nerve conduction,and BAEP could find the electro physiologic ab-normality in nervous system,and guide clinical intervention.

Objective: To evaluate the incidence of postoperative venous thromboembolism (VTE) after thoracic surgery and its characteristic. Methods: This was a single-center, prospective cohort study. Patients undergoing major thoracic surgeries between July 2016 and March 2017 at Department of Thoracic Surgery, Beijing Chaoyang Hospital Affiliated to Capital Medical University were enrolled in this study. Besides the routine examination, all patients were screened for deep venous thrombosis (DVT) by using noninvasive duplex lower-extremity ultrasonography after surgery. CT pulmonary angiography (CTPA) was carried out if patients had one of the following conditions including typical symptoms of PE, high Caprini score (>9 points) or new diagnosed postoperative DVT. Caprini risk assessment model was used to detect high risk patients. No patients received any prophylaxis of VTE before surgery. Further data was analyzed for identifying the incidence of postoperative VTE. The t-test, χ² test or Wilcoxon rank-sum test was used to analyze the quantitative data and classification data, respectively. Results: Totally 345 patients who undergoing major thoracic surgery were enrolled in this study including 145 benign diseases and 200 malignant diseases.There were 207 male and 138 female, aging from 15 to 85 years. Surgery procedures included 285 lung surgeries, 27 esophagectomies, 22 mediastinal surgeries and 11 other procedures. The overall incidence of VTE was 13.9% (48 of 345) after major thoracic surgery including 39 patients with newly diagnosed DVT (81.2%), 1 patient with PE (2.1%) and 8 patients with DVT+ PE (16.7%). The median time of VTE detected was 4.5 days postoperative. There were 89.6% (43/48) VTE cases diagnosed in 1 week. The incidence of VTE was 9.0% in patients with benign diseases, while 17.5% in malignant diseases (χ²=5.112, P<0.05). The incidence of VTE in patients with pulmonary diseases was 12.6%, among that, in patients with lung cancer and benign lung diseases was 16.4% and 7.5 % (χ²=4.946, P<0.05), respectively. Regarding to Caprini risk assessment model, the incidence of VTE in low risk patients, moderate risk patients (Caprini score 5 to 8 points)and high risk patients(≥9 points)were 0(0/77), 15.2%(33/217) and 29.4%(15/51), respectively(Z=-12.166, P<0.05). In patients with lung cancer, 98.2% of patients were moderate risk or high risk; only 3 cases scored low risk. The incidence of VTE in moderate risk and high risk patients was 13.4%(18/134) and 32.1%(9/28), respectively, while it was 0(0/3) in low risk patients. Conclusion s The overall incidence of VTE after major thoracic surgeries is 13.9%, and the incidence of VTE after lung cancer surgeries was 16.4%. Most of the VTE cases occurr within one week after the surgery. Caprini risk assessment model can identify high risk patients effectively.

This study aims to identify the chemical constituents from Callicarpa kwangtungensis and determine their activities. MCI, ODS, and Sephadex LH-20 chromatography and semi-preparative HPLC were employed to separate the chemical constituents. A total of 15 compounds were separated, and their structures were identified on the basis of spectroscopic analysis and comparison with the data in relevant literature. Specifically, the 15 compounds were 3-O-α-L-rhamnopyranosyl-6-O-β-D-apiofuranosyl-4-O-E-caffeoyl-D-glucopyranoside(1), 3,6-O-α-L-dirhamnopyranosyl-4-O-E-caffeoyl-D-glucopyranoside(2), β-OH-forsythoside B(3), β-OH-poliumoside(4),(+)-lyoniresinol-3α-O-β-D-apiofuranosyl-(1→2)-β-D-glucopyranoside(5),(+)-lyoniresinol-3α-O-β-D-glucopyranoside(6),(-)-lyoniresinol-3α-O-β-D-glucopyranoside(7), kelampayoside A(8), descaffeoylpoliumoside(9), acteoside(10), alyssonoside(11), poliumoside(12), isacteoside(13), acetyl forsythoside B(14), and forsythoside B(15). Compounds 1 and 2 were novel, and the NMR data of compounds 3 and 4 were reported here for the first time. Furthermore, the hemostatic activities of the extract and abundant ingredients(compounds 12 and 15) of C. kwangtungensis were determined with Yunnan Baiyao as the positive control and normal saline as the negative control. The extract and compounds 12 and 15 significantly shortened the tail tip bleeding time in mice.
