To investigate the effects of intratracheal instillation of PM2.5 suspension on bleomycin (BLM)-induced pulmonary fibrosis in mice and the intervention of neotuberostemonine (NTS), the BLM dose (1.5 or 3.0 U/kg) and PM2.5 frequency (1 or 2 times per week) were studied by factorial experiment design. After intratracheal instillation of BLM (1.5 or 3.0 U/kg) on day 0, PM2.5 (5 mg/kg) was intratracheally injected to mice once or twice a week from day 1 to day 21, and the mice in the treatment group were given 30 mg/kg NTS by gavage once a day from day 8 to day 21. The degree of pulmonary fibrosis was evaluated by lung coefficient, hydroxyproline (HYP) content, HE staining and Masson staining lung sections as well as their semi-quantitative index (HE inflammatory score and collagen volume fraction, CVF). The results showed that the HE scores increased significantly in mice singly given PM2.5 once a week, the HYP content and HE score increased in mice singly given PM2.5 twice a week, but their CVF values did not significantly increase. However, the CVF values increased significantly in mice treated with PM2.5 and BLM co-infusion. These results suggested that PM2.5 (administered singly) could significantly increase BLM-induced collagen deposition and greatly aggravate pulmonary fibrosis although it mainly caused pulmonary inflammation rather than pulmonary fibrosis. NTS could significantly reduce the CVF value and α-SMA protein level of the model mice. It can be concluded that PM2.5 has great influence on patients with respiratory diseases, while NTS can improve pulmonary fibrosis induced by the combination of PM2.5 and BLM.

Objective To evaluate the correlation between three-dimensional histogram vascular indexes of ovarian tumors and microvessel density (MVD).Methods Fifty-seven patients with ovarian cystic-solid or solid masses from Beijing Obstetrics and Gynecology Hospital,Capital Medical University were evaluated by three-dimensional (3D) power ultrasound within one week before surgery from January 2008 to December 2009.We captured 3D power imaging in the interested and solid areas of tumors,and used three-dimensional histogram from virtual organ computer-aid analysis (VOCAL) to calculate vascularization index (Ⅵ),flow index (FI) and vascularization-flow index (VFI).After operation the specimens underwent immunohistochemistry staining and MVD and vascular endothelial growth factor (VEGF) were calculated.Two independent-samples t tests were used to compare MVD between ovarian benign and malignant tumors.Rank sum test was used to compare VEGF.Spearman was used to analyze the relationship between 3D PD vascular indices and MVD.Results Sixty-two ovarian masses in 57 patients were confirmed by pathology (5 cases were bilateral tumors),including 22 benign and forty malignant messes (including eight borderline tumors).Fifty-four tumors underwent immunohistochemistry staining.MVD and VEGF were calculated.Both of MVD and VEGF in ovarian malignant tumors were obviously higher than those in benign ones (t=-5.255,Z=-3.868,both P < 0.01).Both of Ⅵ and VFI were positive correlative to MVD (r=0.295,0.280,both P < 0.05).Conclusions There was a positive correlation between vascular indexes and microvessel density.The vascular indexes could reflect the density of angiogenesis in ovarian tumors before surgery,and they could provide valuable information for early-stage diagnosis of ovarian cancer.

Objective:To evaluate a novel distraction reductor in the surgical treatment of unstable distal radius fractures with metaphyseal volar comminution.Methods:From January 2019 to December 2020, 27 patients with unstable distal radius fracture complicated with metaphyseal volar comminution were treated at Department of Orthopaedics, Zhoupu Hospital Affiliated to Shanghai University of Medicine & Health Sciences. They were 6 males and 21 females, with an age of (69.4±9.4) years. All fractures were unilateral and closed, involving the right side in 17 cases and the left side in 10 cases. All patients were treated by internal fixation with an anatomical locking plate through the volar approach and the novel distraction reductor was used to reduce the fracture ends. Regular imaging examinations were performed to evaluate the reduction, maintenance and union of fractures after surgery. One year after operation, the curative efficacy was assessed by evaluation of the range of wrist motion, Disabilities of the Arm, Shoulder and Hand (DASH) score, Gartland-Werley score and Bartra radiology score.Results:All the operations went on successfully with a duration of (92.3±8.9) min. All the incisions healed primarily. The follow-up time was (15.9±2.9) months. The radial height, palmar tilt, ulnar inclination and articular surface step-off immediately after operation [(11.23±1.51) mm, 12.10°±3.44°, 20.54°±3.44°, and (0.95±0.42) mm] were not significantly lost compared with those one year after operation [(11.22±1.55) mm, 12.07°±3.44°, 20.51°±3.33°, and (0.93±0.40) mm] (all P>0.05). One year after operation, the range of wrist motion was good with dorsiflexion of 59.7°±5.5°, palm flexion of 63.0°±9.1°, pronation of 66.5°±5.5°, supination of 61.2°±5.6°, radial deviation of 22.7°±4.8°, and ulnar deviation of 30.3°±6.1°; DASH score was 13.5±5.5; Bartra radiology score was 88.6±6.5, giving an excellent and good rate of 88.9% (24/27);Gartland-Werley score was 2.7±2.1, giving an excellent and good rate of 92.6% (25/27). Follow-ups observed no poor fracture healing, internal fixation failure, tendon or nerve injury or traumatic arthritis. Conclusion:In the surgical treatment of unstable distal radius fractures with metaphyseal volar comminution, the novel distraction reductor can lead to ideal reduction of displaced fractures and effectively correct the shortening caused by volar cortex comminution to achieve satisfactory functional effects in clinic.

ObjectiveTo explore the syndrome elements and evolving patterns of patients with hepatitis B virus-related acute on chronic liver failure (HBV-ACLF) at different stages. MethodsClinical information of 1,058 hospitalized HBV-ACLF patients, including 618 in the early stage, 355 in the middle stage, and 85 in the late stage, were collected from 18 clinical centers across 12 regions nationwide from January 1, 2012 to February 28, 2015. The “Hepatitis B-related Chronic and Acute Liver Failure Chinese Medicine Clinical Questionnaire” were designed to investigate the basic information of the patients, like the four diagnostic information (including symptoms, tongue, pulse) of traditional Chinese medicine (TCM), and to count the frequency of the appearance of the four diagnostic information. Factor analysis and cluster analysis were employed to determine and statistically analyze the syndrome elements and patterns of HBV-ACLF patients at different stages. ResultsThere were 76 four diagnostic information from 1058 HBV-ACLF patients, and 53 four diagnostic information with a frequency of occurrence ≥ 5% were used as factor analysis entries, including 36 symptom information, 12 tongue information, and 5 pulse information. Four types of TCM patterns were identified in HBV-ACLF, which were liver-gallbladder damp-heat pattern, qi deficiency and blood stasis pattern, liver-kidney yin deficiency pattern, and spleen-kidney yang-deficiency pattern. In the early stage, heat (39.4%, 359/912) and dampness (27.5%, 251/912) were most common, and the pattern of the disease was dominated by liver-gallbladder damp-heat pattern (74.6%, 461/618); in the middle stage, dampness (30.2%, 187/619) and blood stasis (20.7%, 128/619) were most common, and the patterns of the disease were dominated by liver-gallbladder damp-heat pattern (53.2%, 189/355), and qi deficiency and blood stasis pattern (27.6%, 98/355); and in the late stage, the pattern of the disease was dominated by qi deficiency (26.3%, 40/152) and yin deficiency (20.4%, 31/152), and the patterns were dominated by qi deficiency and blood stasis pattern (36.5%, 31/85), and liver-gallbladder damp-heat pattern (25.9%, 22/85). ConclusionThere are significant differences in the distribution of syndrome elements and patterns at different stages of HBV-ACLF, presenting an overall trend of evolving patterns as "from excess to deficiency, transforming from excess to deficiency", which is damp-heat → blood stasis → qi-blood yin-yang deficiency.
