Objective To study the inhibition of AP-1 transcription factor activity by Hint1 gene over expression in HepG2 cell lines. Methods The Hintl gene was amplified, and then was inserted into the pcDNA3/HA eukaryotic expression plasmid. The constructed pHA-Hint1 plasmid was confirmed by DNA sequencing. The pHA-Hint1 was transfected into the HepG2 human hepatoma cells. Semi-quantitative RT-PCR and Western-blot were used to detecte the expression of HA-Hint1. The HepG2 cells were co-transfected with pHA-Hint1 and pAP-1/Luc luciferase reporter. At 36 h after transfection, luciferase assay system was used to detect the AP-1 transcription factor activity. Results The constructed pHA-Hint1 was confirmed by DNA sequencing, pHA-Hint1 gene transduction through lipofectine induced over-expression in HA-Hint1 mRNA (t =3.89, P<0.05) and HA-Hintl protein (t=3. 12, P<0.05). Co-transfection of Hint1 gene inhibits AP-1 luciferase activity. Cotransfection with increased concentration of a pHA-Hint1 plasmid (0 μg/ml, 0. 5 μg/ml, 1.0 μg/ml, 1.5 μg/ml, 2. 0 μg/ml) produced a concentration-dependent inhibition of AP-1 transcription factor activity. At the concentration of 1.5 μg/ml, and 2.0 μg/ml, the activity inhibition reaches significant difference ( F = 72. 009, P < 0. 05 ). Conclusion Over-expression of Hintl can, at least in part, inhibit the AP-1 transcription factor activity in HepG2 cells.

Objective To investigate the psychological demands of caregivers who take care of severe craniocerebral trauma patients, and to analyze different psychological needs of caregivers in different relation, such as parents, spouses, children, brothers and sisters. Methods We used the Critical Care Family Needs Inventory to investigate 391 relatives of patients in neurosurgical intensive care unit in four hospitals by stratified sampling, in order to understand the psychological demands of people who take care of severe craniocerebral trauma patients. Results The total demand score of 391 caregivers was (136. 63 ± 18. 56),which was at the moderate level. There was significant different demand of different relative caregivers in information factor, proximity factor and assurance factor (F=5. 103, 5. 032, 7. 811, respectively;P<0. 01). Conclusions The psychological demands of caregivers who take care of severe craniocerebral trauma patients had relative high psychological needs. The clinic staffs should pay attention to the difference of demand, and give them psychological care to reduce their psychological stress and prevent mental problems.

Objective To explore the influence of superior support on job-related well-being of nurses. Methods From January 2013 to March 2013, we went on investigating 608 clinical nurses from 4 primary hospitals, 1 secondary hospitals and 2 territory hospitals in Shanghai by stratified sampling method, measured by job-related welling-being scale, positive and negative affect scale, supervisor support questionnaire and personal information questionnaire. Results The total score of 608 nurses′psychological well-being acquired (162. 15 ± 25. 15), while the recognition of superior support was (27. 56 ± 5. 52). There was a positive correlation between superior support and psychological well-being (r =0. 544,P <0. 01), as well as positive emotional experience level of nurses (r =0. 402,P <0. 01), but a negative correlation between superior support and nurses′negative emotional experience level (r= -0. 368,P<0. 01). Conclusions Superior support has an important effect on nurses′ psychological well-being and positive emotional experience in the working environment. Enhancing superior support is to help nurse experience the happiness of work, at the same time to help the nurse earn mental and physical well-being, and reduce occupational tiredness and work stress.

Objective:To study minimally invasive treatment using percutaneous transhepatic choledochoscopic lithotripsy (PTCSL) to treat complicated hepatolithiasis.Methods:Patients with complicated hepatolithiasis who were treated at the Second Affiliated Hospital of Kunming Medical University from July 2017 to September 2021, were included into this study. There were 48 patients treated with PTCSL (the PTCSL group) and 150 patients treated with conventional open hepatectomy (the OH group). Propensity score matching (PSM) was used to match 40 patients in the PTCSL group with 40 patients in the OH group. There were 11 males and 29 females, aged 32 to 85 (59.3±12.7) years in the PTCSL group and 15 males and 25 females, aged 20 to 74 (55.4±10.9) years in the OH group. Theoperation time, intraoperative blood loss, hospitalization time, hospitalization cost, incidences of major complications (including pleural effusion, biliary bleeding), residual stone rates and recurrence rates were analyzed.Results:Baseline data were comparable between groups after PSM. For the PTCSL group, the operation time was (135.8±42.6) minutes, intraoperative bleeding volume 32.5(20.0, 50.0) ml, hospitalization time 13.5(11.0, 18.0) days, and hospitalization expense 3.4(2.9, 5.0) wanyuan compared with the corresponding figures in the OH group with operation time (350.7±113.8) minutes, intraoperative bleeding volume 475.0(200.0, 900.0) ml, hospitalization time 24.0(17.3, 28.8) days, and hospitalization expense 6.6(5.0, 8.9) wanyuan. The differences between the two groups were statistically significant (all P<0.05). The overall complication rate was 2.5%(1/40) in the PTCSL group and 22.5%(9/40) in the OH group (χ 2=7.31, P=0.007). The residual stone rate of 20.0%(8/40), stone recurrence rate of 17.5%(7/40), compared with the OH group with the stone residual rate of 27.5%(11/40), stone recurrence rate of 12.5%(5/40). There was no significant difference between the two groups in both the stone residual rates and stone recurrence rates (both P>0.05). Conclusion:In treatment of complex hepatolithiasis, the stone residual rate after repeated PTCSL was comparable to traditional open hepatectomy. PTCSL had the advantages of shorter operation time, less bleeding, lower hospitalization time, lower complication rate and lower hospitalization cost. PTCSL is worthy of wider application and popularization.

Objective:To explore the value of laparoscopic and endoscopic cooperative surgery with the patient lying on supine position under general anesthesia in the operation of type I Mirizzi syndrome with choledocholithiasis.Methods:From Jan 2018 to Jan 2020, 53 cases of Mirizzi syndrome with choledocholithiasis undergoing laparoscopic and endoscopic cooperative surgery (preLC+ ERCP+ EST) at the Second Affiliated Hospital of Kunming Medical University were retrospectively analyzed.Results:53 patients successfully underwent LC without conversion to open surgery, and 2 patients failed in ERCP + EST attempt, with a success rate of 96.2%. One patient developed pancreas pseudocyst as a result of post-operative hemorrhagic necrotizing pancreatitis. Two patients suffered from chronic pancreatitis. Three patients complaining postoperative upper abdominal discomfort were finally diagnosed as stump cystic duct inflammation by MRCP, and no abnormalities were found in the follow-up of the remaining cases.Conclusion:Laparoscopic and endoscopic cooperative surgery in the treatment of patients with type I Mirizzi syndrome combined with choledocholithiasis is minimally invasive and effective.

BACKGROUND: Lung cancer is still the malignant tumor with the highest morbidity and mortality in China. Lung adenocarcinoma is the most common subtype, and the number of lung cancer presenting as mixed ground glass nodule (mGGN) in imaging is gradually increasing. Visceral pleural invasion (VPI) is an important factor affecting the prognosis of mGGN type lung adenocarcinoma. The aim of the study is to explore and analyze the risk factors for VPI in mGGN type lung adenocarcinoma. METHODS: From November 2016 to November 2019, 128 patients with mGGN lung adenocarcinoma underwent radical surgical resection in the First Affiliated Hospital of Nanjing Medical University. Their clinical data, including imaging, pathological and biological features, were collected and analyzed retrospectively. There were 40 males and 88 females, aged 60.3±9.3 years ranging from 30 to 81 years. Single factor Chi-square test and multivariate Logistic regression were used to analyze the risk factors of VPI in mGGN type lung adenocarcinoma. RESULTS: Among 128 mGGN patients who met the inclusion criteria, 57 cases were pathologically confirmed with pleural invasion. Between the VPI (+) and VPI (-) group (P<0.05), there were significant differences in gender, maximum diameter of solid component, consolidation tumor ratio (CTR), spicule sign, history of lung disease, family history of hypertension, relation of lesion to pleura (RLP), coursing relationship between bronchi and nodules. In multivariate Logistic regression analysis, RLP (OR=3.529, 95%CI: 1.430-8.713, P=0.006) and coursing relationship between bronchi and nodules (OR=3.993, 95%CI: 1.517-10.51, P=0.005) were found to be independent risk factors for VPI (P<0.05). CONCLUSIONS The possibility of VPI in m GGN lung adenocarcinoma should be evaluated by combining these parameters in clinical diagnosis and treatment. As independent risk factors, RLP and coursing relationship between bronchi and nodules are instructive to identify VPI in mGGN type lung adenocarcinoma.
