Objective To observe selective cyclooxygenase-2 (COX-2) inhibitor celecoxib on the cell migration, MMP-9 and VEGF expression of human gastric cancer SGC-7901. Methods In vitro culture of SGC-7901 cells, the cells were divided into blank control group and celecoxib treatment group (different concentrations of celecoxib 25, 50 and 100μmol/L). SGC-7901 cells were treated with celecoxib for 24 h. The effect of celecoxib on cell migration of SGC-7901 was detected by the damage repair experiment. RT-PCR assay was used to detect the effect of celecoxib on MMP-9 mRNA and VEGF mRNA expressions in SGC-7901 cells. Results The migration distance of SGC-7901 cells was decreased with the increased concentration of celecoxib. There were significant differences between medium-dose and high-dose celecoxib groups and the control group. RT-PCR assay showed that MMP-9 mRNA and VEGF mRNA expressions in gastric cancer SGC-7901 were significantly decreased with the increased concentration of celecoxib, and there was a significant difference compared with those of control group (P＜0.05). Conclusion Celecoxib can inhibit migration of human gastric cancer SGC-7901 cells, which may be related to the inhibition of COX-2 downstream of MMP-9 and VEGF expressions.

Primary liver cancer (PLC) is one of the most common malignant tumors with characteristics of strong invasiveness and poor prognosis. The morbidity and mortality of PLC rank among the top malignant tumors in the world. More than half of the world′s liver cancer occurs in China, which seriously threatens the health and life of Chinese people. Due to the imperceptible initial symptoms, most patients are not diagnosed until their tumors have progressed to be in advanced stage, and lose the chance for curative hepatectomy. At present, non-surgical treatment options, including interventional embolization, ablation, radiotherapy, chemotherapy, and systemic chemotherapy, play an increasingly prominent role in the comprehensive treatment of liver cancer. The authors briefly review the current status and research progress of the non-surgical treatment for liver cancer.

Objective:To compare proximal humerus internal locking system (PHILOS) and Multiloc intramedullary nail in the treatment of proximal humerus fracture-anterior dislocation.Methods:A retrospective study was performed to analyze the data of 33 patients with proximal humerus fracture-anterior dislocation who had been treated by open reduction and internal fixation from June 2015 to April 2021 at Department of Upper Limbs, Zhengzhou Orthopaedic Hospital. According to methods of internal fixation, the patients were divided into an extramedullary group and an intramedullary group. In the extramedullary group of 18 cases subjected to internal fixation with PHILOS, there were 8 males and 10 females with an age of (53.3 ± 10.6) years, and 1 2-part fracture, 15 3-part fractures and 2 4-part fractures by the Neer classification. In the intramedullary group of 15 cases subjected to internal fixation with Multiloc intramedullary nail, there were 8 males and 7 females with an age of (51.5 ± 11.2) years, and 14 3-part fractures and 1 4-part fracture by the Neer classification. The 2 groups were compared in terms of incision length, operation time, intraoperative blood loss, postoperative complications, and visual analog scale (VAS), range of shoulder motion, and Constant-Murley score at postoperative 12 months.Results:The 2 groups were comparable due to insignificant differences in their preoperative general data ( P>0.05). All patients were followed up for (20.8 ± 4.7) months. The incision length in the intramedullary group [(11.6 ± 1.7) cm] was significantly shorter than that in the extramedullary group [(17.6 ± 2.0) cm], and the intraoperative blood loss in the former [(106.7 ± 34.4) mL] was significantly lower than that in the latter [(151.7 ± 45.7) mL] ( P<0.05). The VAS scores at 1 week and 1 month after surgery [2.0 (2.0, 3.0) and 0.0 (0.0, 1.0) respectively] in the intramedullary group were significantly lower than those in the extramedullary group [3.0 (3.0, 3.3) and 1.0 (0.0, 1.3) respectively] ( P<0.05). The external rotation of the shoulder at the last follow-up in the intramedullary group (65.3° ± 15.5°) was significantly larger than that in the extramedullary group (50.6° ± 13.9°) ( P<0.05). There were no significant differences in operation time, incidence of postoperative complications, VAS score at 12 months after operation, Constant-Murley score or range of shoulder motion at the last follow-up between the 2 groups ( P>0.05). Conclusions:In the treatment of proximal humerus fracture-anterior dislocation, open reduction and internal fixation with both PHILOS and Multiloc intramedullary nail can result in a favorable prognosis when the fracture-dislocation is well reduced and fixated. However, the Multiloc intramedullary nail may lead to better early pain relief, less surgical invasion, and better functional recovery of the external rotation of the shoulder.

Objective To assess the value of Stroop smartphone application (EncephalApp-Stroop) in screening minimal hepatic encephalopathy (MHE).Methods Ninety hepatitis B cirrhotic patients without overt hepatic encephalopathy (OHE),admitted to our hospital from January 2015 to February 2016,and other 90 healthy volunteers were chosen in our study.Psychometric hepatic encephalopathy scale (PHES) and EncephalApp-Stroop were performed.Normal reference value formulas were established based on the 5 psychometric tests at PHES in healthy controls.EncephalApp-Stroop contained "off'state (neutral stimuli) and "on" state (incongruent stimuli).The time of completing five correct runs and the number of rtms in "on" and "off'states were calculated.PHES was used to diagnose MHE as gold standard to compare the results of OHE patients and healthy subjects and the results of patients with/without MHE.EncephalApp-Stroop results were compared with PHES results by receiver operator characteristic analysis.Results OHE patients had significantly longer time than healthy subjects in Stroop "on" and "off'states (P＜0.05).Traditionally,the total scores of PHES below-4 were diagnosed as MHE,and all the 90 patients taking PHES as gold standard,52 patients were diagnosed as MHE.The time at Stroop "on" and "off'states and the number of trials completing 5 correct runs were longer/larger in patients with MHE as compared with those in patients without MHE,with significant differences (P＜0.05).The validation cohort of EncephalApp-Stroop showed 87％ sensitivity and 79％ specificity.Conclusion The EncephalApp-Stroop is a valid,short and reliable tool for screening MHE.

Objective:To evaluate the clinical efficacy of the axillary approach in the treatment of scapular glenoid fracture.Methods:A retrospective analysis was performed of the 12 patients who had been treated for scapular glenoid fracture from November 2019 to April 2021 at Department of Upper Limb Orthopaedics, Zhengzhou Orthopaedic Hospital. They were 4 males and 8 females, aged from 30 to 75 years (mean, 53.5 years). According to the Ideberg classification, there were 2 cases of type Ⅰa, 9 cases of type Ⅱ and one case of type Ⅴa. All cases were treated through the axillary approach. Two patients complicated with anterior shoulder dislocation were treated with manual reduction under anesthesia before operation and the other 10 cases with special plate fixation through the axillary approach. The 3 patients complicated with fracture of greater tuberosity were fixated with a special plate through the lateral shoulder split deltoid approach. Constant-Murley score, visual analogue scale (VAS) and Hawkins grading were used at the last follow-up to evaluate shoulder function, pain and stability after operation.Results:All patients were followed up for 9 to 20 months (mean, 14.4 months). The operation time ranged from 55 to 110 min (mean, 76.3 min), intraoperative bleeding from 60 to 160 mL (mean, 103.8 mL), and hospital stay from 8 to 14 d (mean, 11.1 d). All incisions healed primarily and all scapular glenoid fractures got united 6 months after operation. The last follow-up showed no shoulder instability, neurovascular injury or internal fixation failure. At the last follow-up, the range of motion of the shoulder was 159.2°±26.1° in forward bending, 156.7°±29.6° in abduction, 48.3°± 15.3° in external rotation (neutral position), and 73.3°±12.3° in internal rotation (neutral position), and the Constant-Murley score was (94.0±5.3) points. The range of motion of the shoulder and Constant-Murley score were significantly improved compared with those before operation (10.8°±11.6°, 7.5°±11.4°, 5.8°±10.0°, 42.5°±16.0° and 4.9±4.0, respectively) (all P<0.05). The VAS score was 0 in 11 patients and 2 in one patient at the last follow-up. Conclusion:The axillary approach is feasible for the treatment of scapular glenoid fracture, because it is hidden and less invasive, leading to good clinical outcomes.

Objective:To investigate the effect of multi line therapy for lung adenocarcinoma transformed into small cell lung cancer (SCLC), and review and discuss the related literature.Methods:Combined with the clinical examples of lung adenocarcinoma transformed SCLC after treatment with anti epidermal growth factor receptor tyrosine kinase inhibitors (EGFR TKIs), the diagnostic process and multi line treatment plan of transformed SCLC were analyzed, and the therapeutic effect was evaluated by imaging. At the same time, it was reviewed and discussed in combination with relevant literature.Results:Serological tumor markers were significant for the diagnosis of transformed SCLC after EGFR-TKI treatment of lung adenocarcinoma, and pathology was still the gold standard for its diagnosis. The multiline therapy of SCLC has certain effect on transformed small cell lung cancer.Conclusion:The overall prognosis of lung adenocarcinoma transformed into SCLC after EGFR TKIs treatment is poor, so it is necessary to diagnose and treat it as early as possible, evaluate the effect of imaging in time, and make treatment adjustment quickly.

Objective:To explore the effects of mechanical factors on the morphology of the growth plate and proximal femur development, in order to provide a mechanical basis for the mechanism of Cam lesions in femoral acetabular impingement (FAI).Methods:Using CT scan data of hip joint from adolescents, we constructed three-dimensional finite element models of normal and extended proximal femoral epiphyseal growth plates. Dynamic mechanics and position data from daily activities (walk, stand on one and two feet, go upstairs and downstairs, sit and stand up, squat and stand up) and basketball layup drills were collected from five healthy volunteers using the Vicon system. The mean values of femoral head mechanical loads and positions at peak values, movement onset, and termination were selected for finite element analysis to observe the distribution of equivalent stress, normal stress, and shear stress on the two growth plate models under different activity modes.Results:Successful construction of three-dimensional finite element models for normal and extended proximal femoral epiphyseal growth plates was achieved. Mechanical load values and spatial positions of the femoral head during daily activities and layup movements were obtained. In daily activities, peak equivalent stress values for normal and extended growth plates ranged from 1.6 to 11.0 MPa; compressive stress ranged from 1.7 to 12.0 MPa; tensile stress ranged from 0.5 to 10.0 MPa; and shear force ranged from 0.4 to 7.1 MPa. The compressive stress during walking, standing on one or both feet, going up and down stairs, sitting and standing, and squatting was concentrated in the central and lateral areas; tensile stress was concentrated in the central and medial areas; shear force was concentrated in the medial area and the anterior and posterior edges of the growth plate. During a layup, the compressive stress in the center, outer upper side, and medial edge of the growth plate of the normal model was notably concentrated, with peaks fluctuating between 5.5-19.0 MPa, 5.7-11.0 MPa, and 5.4-7.3 MPa respectively; tensile stress and shear force were concentrated at the inner and outer edges as well as in the central area, with peaks fluctuating between 3.0-24.0 MPa and 3.0-26.0 MPa respectively, these values were significantly different from those observed during daily activities. For the elongated growth plate, compressive stress was concentrated at the central and lateral edges with peaks fluctuating between 17.0-41.0 MPa and 17.0-38.0 MPa respectively; simulated shear stress and tensile stress showed significant concentration at peaks fluctuating between 4.9-34.0 MPa, also significantly different from those observed during daily activities.Conclusion:The difference in mechanical distribution between daily activities, basketball layup training, as well as between normal and extended growth plates may be the mechanical initiating factor in the development of extended growth plates and the formation of Cam lesions, it may be the mechanical initiating factor for the development of extended growth plates and the collision of Cam lesions in FAI.
