Objective@#In order to explore the mutual predictive relationship between passive social network site use and fear of missing out.@*Methods@#A one-year longitudinal design was adopted. 652 college students were convinently selected from 2 colleges in Heilongjiang Province measured twice by Passive Social Network Site Use Scale (PSNSUS) and Fear of Missing Out Scale (FOMOS). The structural equation model was used to conduct cross-lagged analysis.@*Results@#There was a significant positive correlation between PSNSUS and FOMOS scores measured twice(r=0.44,0.45, P<0.01). The results of cross-lagged analysis indicated that, after controlling for the correlation between PSNSUS and FOMOS at time 1 and time 2, pre-test PSNSUS had a significant effect on post-test FOMOS (β=0.55,P<0.01), and the predictive effect was stronger among female students. pre-test FOMOS has a significant effect on post-test PSNSUS (β=0.11, P<0.05), and the predictive effect was stronger among male students.@*Conclusion@#It suggests that passive social network site use and fear of missing out could predict eachother in college students.

@#Objective    To explore the safety and effectiveness of video-assisted thoracoscopic surgery (VATS) pneumonectomy for bronchiectasis. Methods    The clinical data of 164 patients undergoing VATS pneumonectomy or open thoracotomy for bronchiectasis in our hospital from March 2002 to July 2012 were retrospectively analyzed. Patients were divided into two groups according to different surgical methods: a thoracotomy group (122 patients, 63 males, 59 females) and a thoracoscopic surgery group (42 patients, 15 males, 27 females). Surgical and follow-up indicators were compared between the two groups. Results    There was no difference between the two groups in the blood loss, operation time, perioperative mortality or complication. However patients undergoing VATS had shorter length of postoperative stay than those undergoing thoracotomy (6.9±2.6 d vs. 8.1±3.1 d, P=0.030). In the thoracoscopic surgery group, 3 patients were lost to follow-up and in the thoracotomy group, 5 patients were lost to follow-up. In a median follow-up of 51 months (ranging from 2 to 116 months), 36 patients (92.3%) fully recovered with no sputum or haemoptysis and 3 (7.7%) partially recovered with a reduced sputum or haemoptysis in the thoracoscopic surgery group; 105 (89.7%) fully recovered with no sputum or haemoptysis, 10 (8.5%) partially recovered with a reduced sputum or haemoptysis while 2 (1.7%) without any improvement in the thoracotomy group with no statistical difference (P=0.700). Conclusion    VATS pneumonectomy for bronchiectasis is equivalent to thoracotomy in terms of safety and effectiveness, and can be used as an alternative surgical procedure for the treatment of bronchiectasis.

@#Objective    To present the preliminary clinical experience of robot assisted trans-subxiphoid (extended) thymectomy in patients with thymic neoplasms or myasthenia gravis. Methods    A total of 62 patients (34 males and 28 females at an average age of 38±11 years) suffering from thymic neoplasms or myasthenia gravis who underwent robotic (extended) thymectomy via subxiphoid approach were included in our department between August 2016 and August 2017. All of the operation were completed through 4 ports. In details, the observation hole was created just below the xiphoid process, two ports for arm 1 and arm 2 were created below bilateral subcostal arch at the midclavicular line, and trocar for arm 3 was placed in the 5th or 6th intercostal space at the anterior axillary line, respectively. Patients with thymic neoplasms received thymectomy. Patients with myasthenia gravis received extended thymectomy. Results    All the patients experienced uneventful operations. The mean operative time was 116.0±34.0 min. The mean intraoperative blood loss was 5.6±4.3 ml. The mean postoperative hospital stay was 4.0±2.2 days. There was no intra-operational massive hemorrhage, mortality, conversion or postoperative complication during the postoperative and follow-up period. Conclusion    Robotic trans-subxiphoid thymectomy is safe and feasible, which is a promising technique for extensive application.

ABSTRACT Objective: To establish the detrusor overactivity (DO) model induced by visceral hypersensitivity (VH) and investigate the relationship between mast cell (MC) infiltration and DO. Materials and Methods: Sixty rats are divided into 4 groups randomly: Group 1:Baseline group; Group 2: DO group; Group 3: CON group; Group 4: VH group. The colorectal distension (CRD) and abdominal withdral reflex (AWR) scores are performed to evaluate VH. The cystometric investigation and histological test of MC infiltration are assessed. Results: The threshold pressure of CRD in the VH group is significantly lower than that in the CON group (P<0.001). At the distension pressure ≥20 mmHg, the AWR scores of the VH group are significantly higher than those of the CON group (10 mmHg: P=0.33; 20 mmHg: P=0.028; 40 mmHg: P<0.001; 60 mmHg: P<0.001; 80 mmHg: P<0.001). DO model is successfully established in the VH group (DO rate=100%). Compared with the CON group, the numbers of MC infiltration are significantly increased in the VH group, including submucosa of bladder (P<0.001), mucosa lamina propria/mesentery of small intestine (P<0.001), and mucosa lamina propria/mesentery of large intestine (P<0.001). Furthermore, more MC activation as well as degranulation are observed in the VH group. Conclusions: It is indicated that DO model can be established in the VH rats. The MC infiltration may play an important role in DO induced by VH, and may be helpful to understand the mechanisms of DO in VH patients.

BACKGROUND: Transforming growth factor (TGF)-ß is involved in many physiologic processes, it often promotes metastasis, and its high expression is correlated with poor prognosis. In the present study, we analyzed the correlation between transforming growth factor beta 1 (TGF-ß1) expression and prognosis in intrahepatic cholangiocarcinoma RESULTS: We examined the expression of TGF-ß1 in 78 intrahepatic cholangiocarcinomas by immunohistochemistry and correlated the expression with clinicopathological parameters. TGF-ß1 was expressed in 37 of 78 (47.4 %) intrahepatic cholangiocarcinomas. The expression of TGF-ß1 was significantly correlated with lymph node metastasis, distant metastasis, and tumour recurrence. Patients with TGF-ß1-positive tumours had significantly shorter survival time. In a multivariant analysis, the expression of TGF-ß1 and the tumour stage were independent prognostic factors CONCLUSIONS: Our data suggest that expression of TGF-ß1 is a novel prognostic marker for intrahepatic cholangiocarcinoma.

Objective To improve the model for establishment and evaluation of detrusor overactivity in female Wistar rats. Materials and Methods We ligated the perineal urethra of female Wistar rats and then performed filling cystometry. The probability of detrusor overactivity, bladder capacity, peak voiding pressure and histological changes were investigated. Results Detrusor overactivity ratio of the obstruction group was 32.4%. Bladder capacity increased from 0.273 ± 0.036mL in control group to 0.89 ± 0.19mL in detrusor overactivity group (P < 0.001), and peak voiding pressure increased from 45.9 ± 4.1 cm.H2O to 63.5 ± 17.4cm.H2O (P = 0.007). For obstruction group, compared to no detrusor overactivity rats, detrusor overactivity rats had higher bladder capacity (0.89 ± 0.19mL versus 0.43 ± 0.09mL, P < 0.001) and higher peak voiding pressure (63.5 ± 17.4cm.H2O versus 44.8 ± 6.2cm.H2O, P = 0.005). Detrusor overactivity rats were classified according to peak voiding pressure (49.2 ± 4.2cm.H2O versus 80.8 ± 7.1cm.H2O, P < 0.001). Moreover, bladder weight increased significantly in detrusor overactivity rats (P = 0.003, P = 0.028) and detrusor histological hypertrophy was observed. Conclusions Ligating perineal urethra and filling cystometry with intra-urethral cannula approach is a simple and easily reproducible method to establish and evaluate the model of detrusor overactivity in rats. .

Bone marrow mesenchymal stem cells (BMSCs) are a kind of pluripotent stem cells derived from bone marrows, which can not only support hematopoiesis, but also have capabilities of multidifferentiation, high-proliferation and self-renewing. They have become one of hotspots in stem cell studies. Studies on in vitro intervention with BMSCs with TCMs have made remarkable progress in recent years. According to the findings, some traditional Chinese medicines can promote proliferation of BMSCs, some can inhibit the apoptosis of BMSCs, while others can induce BMSCs to differentiate into multiple cell types, such as osteoblast. Furthermore, some studies also involved relevant action mechanisms. The authors summarized the advance in relevant studies by reference to relevant literatures of this field.
