Methods A total of 121 patients with B-PLG diagnosed by CDU combined with HFU between January 2008 and November 2011 were randomly selected. All of the patients underwent the surgery and had the record of surgical pathological examination results, which were compared with the results of the ultrasonography in order to evaluate the diagnostic accuracy of CDU combined with HFU for B-PLG. Results In 121 patients with B-PLG diagnosed by CDU combined with HFU before the surgery, cholesterol polyp was found in 62 (51.24%), infective polyp was found in 27 (22.31%), adenoma was found in 6 (4.96%), adenocarcinoma was found in 3 (2.48%), gallstones was found in 14 (11.57%), adenomyosis was found in 3 (2.48%), the wall structure gland disorder was found in 3 (2.48%), and submucosal soft nodules was found in 3 (2.48%) after the surgical pathological examination. Coincidence rate between CDU combined with HFU diagnosis and surgical pathological diagnosiswas 78.51% (95/121), and the misdiagnosis rate of CDU combined with HFU was 21.49% (26/121). Conclusion The accuracy of CDU combined with HFU diagnosing B-PLG is high, which can help to prevent precancerous lesion of gallbladder cancer.
ObjectivesTo compare the clinical features and the effects on cognition, emotion, and prognosis of antiepileptic drugs (AEDs) between occipital lobe epilepsy (OLE) and temporal lobe epilepsy (TLE).MethodsWe collected the clinical data of the patients with OLE and TLE from the Department of Neurology, the First Hospital of Jilin University from January 2016 to May 2018. We measured the patients with Mini-mental state examination (MMSE), Montreal cognitive assessment (MoCA), digital span, Auditory verbal memory test (AVMT), Generalized anxiety disorder (GAD-7), Patient health questionnaire-9 (PHQ-9) and Chinese version of the Neurological Disorders Depression Inventory for Epilepsy (c-NDDI-E) and followed up for 1 year.Results① After 1 year’s follow-up, the frequency of the two groups decreased compared with the first visit (Z=3.734, P=0.000) and the extent was similar (Z=−0.290, P=0.772). In group OLE, occipital aura was 45.9% (17 cases) and temporal aura was 37.8% (14 cases). In TLE group, temporal aura was 49.3% (33 cases) and occipital aura 7.5% (5 cases). In OLE group, post-seizure headache was found in 17 cases (45.9%), which was more than the 15 cases (22.4%) in TLE group (χ2=6.210, P=0.013). ② 30 cases (81.1%) in OLE group interictal discharge involved lobes outside occipitotemporal lobe, 4 of which had a wide-lead-involved discharge, and 19 cases (28.4%) in TLE group involved lobes outside temporal lobe, and there was a significant difference between the two groups (χ2=26.592, P=0.000). ③ There was no significant difference in the score of MOCA and AVMT in the group of OLE-A and OLE-B, either the group of TLE-A and TLE-B. The score of AVMT in group OLE-A was higher than that in group TLE-A (t=3.193, P=0.002), and that in group OLE-B was higher than that in group TLE-B (t=2.264, P=0.029). There was no significant difference in GAD-7, PHQ-9, and c-NDDI-E (P>0.05). After follow-up for 1 year, the scores were compared with its initial scales. The score of GAD-7 (Z=−2.561, P=0.010), PHQ-9 (Z=−2.053, P=0.040) and c-NDDI-E (Z=−2.493, P=0.013) all decreased. The score of GAD-7 (r=0.281, P=0.021) and c-NDDI-E (r=0.456, P=0.000) have a positive correlation with the frequency of seizure. Therapeutic effect: In OLE group, the efficiency of carbamazepine or oxcarbazepine group was 58.82% and of levetiracetam group was 83.33%. in TLE group, the efficiency of carbamazepine or oxcarbazepine was 72.50% and of levetiracetam group was 70.00%. There was no significant difference between group OLE and group TLE in the curative effect of carbamazepine or oxcarbazepine group (χ2=1.033, P=0.310) or levetiracetam group (χ2=0.356, P=0.551). After 1 year’s follow-up, the frequency of OLE group was 0.00 (0.000, 2.750) times per month, and the TLE group was 0.00 (0.000, 1.500) times per month. There was no significant difference between the two groups (Z=−0.226, P=0.822). At the follow-up, the frequency of seizure in the two groups was lower than that at the first visit (P=0.000). The frequency of seizure in TLE group was similar to that in OLE group (=−0.648, P=0.517). After 1 year, 5 patients (13.51%) in OLE group were newly diagnosed as refractory epilepsy and 6 patients (9.00%) in TLE group There was no significant difference in the rate of the newly diagnosed refractory epilepsy between the two groups (2=0.524, P=0.469).ConclusionOccipital aura and post-seizure headache are specific to OLE, which can be used as one of the basis for diagnosis of OLE. Epileptiform discharge in OLE is more likely to spread out in multiple cerebral lobes, while epileptiform discharge in TLE is confined to temporal lobe and the area near it. The cognitive impairment in OLE or TLE is not related to the duration of the disease. The degree of depression is positively correlated with the frequency of seizure. The responses to AEDs of OLE and TLE are similar.
ObjectiveTo study the relationship between expression of Caspase-3 and regression of hemangioma. MethodsCaspase-3 expression was detected in 79 hemangiomas and 5 normal skin tissues by immunohistochemistry (SP). ResultsIn 79 hemangiomas, the positive rates of Caspase-3 expression in proliferating, involuting and involuted phases were 52.4%, 91.2% and 83.3%, respectively. The expression of Caspase-3 in involuted and involuting phases was higher than proliferating phase(Plt;0.05，Plt;0.01) and control group(Plt;0.01). There was no statistical difference between the latter two groups (Pgt;0.05). ConclusionCaspase3 is involved in the converting of hemangiomas from proliferating phase into involuting phase. The activation of Caspase-3 may induce apoptosis of endothelial cells, thus leading to the regression of hemagioma.
Abstract: Objective To study the impact of different kinds of mechanical circulation support devices on plasma free hemoglobin(FHb). Methods From Mar. 2004 to Dec. 2005, 20 patients received mechanical circulation support in Fu Wai Hospital, who were divided into 4 groups according to the different type of supporting devices. 9 got extracorporeal membrane oxygenation (ECMO) treatment, 8 received BVS5000 left ventricular support, 2 got MEDOS left ventricular support and 1 received AB5000 left ventricular support. Random control group included 9 cardiotomy patients after CPB supporting and 9 patients with offpump coronary artery bypass grafting during the same period. Parameters such as FHb, Tbil, Dbil, Cr and BUN were monitored throughout the supporting term. The results were compared according to the different types of mechanical circulation support devices. Results The elevation of FHb caused by CPB could be decreased to normal within 1d. However, in BVS5000 group, the elevated FHb level decreased to normal till 2 days later. The others mechanical circulation support devices such as ECMO, MEDOS, AB5000 elevated the FHb throughout the whole supporting period. Compared with those in ECMO group, the patients in BVS5000 group had obviously lower level of FHb since the third day after the beginning of supporting. In patients who got ECMO treatment, there was a trend that the elevation degree of FHb was lower in those with support flow rate less than 2.5 L/min. For most patients got devices support, there was also an elevation of Tbil and BUN level during the supporting period. Conclusion Mechanical circulation support devices, such as ECMO, BVS5000, MEDOS and AB5000, can cause red cell destruction in acceptable level. BVS5000 has much smaller impact on cell destruction than others do in postoperative patients.
Objective To detect the expression and clinical significance of POLD1 gene in non-small cell lung cancer (NSCLC) via bioinformatics method. Methods The expression difference of POLD1 in NSCLC tissue and normal lung tissue was investigated by TIMER database. UALCAN database was used to further verify different expression of POLD1 as well as the relationship between POLD1 expression and clinicopathological characteristics of NSCLC. The correlation between POLD1 gene and prognosis of NSCLC patients was detected by GEPIA and TIMER database. cBioPortal database was used to analyze frequencies of POLD1 gene mutation. POLD1-related protein-protein interaction network was constructed by STRING database. The relationship between POLD1 and immune infiltration was based on TISIDB database. Results The expression of POLD1 gene in lung adenocarcinoma and lung squamous cell carcinoma was significantly higher than that in normal lung tissue. In lung adenocarcinoma, patients with lower POLD1 level showed better prognosis. 1.2% of lung adenocarcinoma patients and 1.8% of lung squamous cell carcinoma patients carried mutated POLD1 gene, mainly missense mutations. POLD1 may interact with POLD2, POLD3, POLD4, POLE, RPA1, PCNA, MSH6, MSH2 and FEN1. The biological processes include DNA replication, mismatch repair, etc. Besides, the expression of POLD1 in NSCLC was correlated with the number of different immune cells. Conclusions The POLD1 gene is highly expressed in NSCLC patients, and negatively related with survival prognosis in patients of lung adenocarcinoma. POLD1 gene may be a potential diagnostic target and prognostic marker in NSCLC.
Objective To summarize the updates of diagnosis and differential diagnosis for hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT) for providing evidences for early diagnosis and treatment of PVTT patients. Methods The related literatures on diagnosis and differential diagnosis for HCC with PVTT in recent years were collected and reviewed. Results The serious complications and tumor metastasis are attributed to the PVTT, then it is necessary to make diagnosis accurately according to clinical symptoms, hematological and imaging examinations. The differential diagnosis of PVTT and portal vein thrombosis, portal sponge degeneration and hepatic arteriovenous shunt diseases should be carried out. Conclusions The diagnosis and differential diagnosis of PVTT cannot rely on a single method, and it requires a comprehensive judgment of various diagnostic methods. More accurate and specific diagnostic methods are needed.
Objective To review the progress of total ankle arthroplasty (TAA) in treatment of end-stage ankle osteoarthritis (AOA). Methods The domestic and foreign literatures about TAA in recent years were reviewed. The current status and progress of TAA were summarized from the results of traditional and computer-assisted TAA clinical outcomes. Results End-stage AOA often leads to severe pain and dysfunction, and arthrodesis is still the main selective treatment option. In recent years, with the advancement of surgical techniques and prosthesis design, TAA which can remain joint mobility has increased gradually, and the surgical results also have significant progress. Accurate prosthesis implant and mechanical alignment restoration are critical factors for TAA, and surgery-related malalignment is correlative to the prosthesis failure. Computer assisted patient-specific guide can simplify the TAA procedures and obtain the accuracy of tibia and talus osteotomy. Conclusion The clinical efficiency of preoperative CT based patient-specific guide technology for TAA needs further clinical follow-up. Meanwhile, it is necessary to further develop intraoperative navigation and robotic surgery system suitable for TAA.

Objective To evaluate the role of guide sheath (GS) utilization in radial endobronchial ultrasound guided transbronchial lung biopsy (EBUS-TBLB) for diagnosis of peripheral pulmonary lesions (PPLs). Methods The clinical data of patients who underwent EBUS-TBLB in Peking University First Hospital from July 2012 to June 2015 were retrospectively reviewed. The patients were divided into three groups,ie. a GS group, a non-GS group, and a double biopsy group. Results A total of 118 patients with 126 PPLs were collected. The overall diagnostic yield of EBUS-guided bronchoscopy was 60.3%. The diagnostic yield of GS group, non-GS group and double biopsy group was 65.4%(36/55), 61.5%(8/13), 59.6%(31/52), respectively. The diagnostic yield of the non-GS group was significantly lower than other two groups when PPLs≤20 mm (χ2=6.8,P=0.033), whereas no significant difference was observed when PPLs>20 mm (χ2=2.301,P=0.301). Conclusion GS significantly improves diagnostic yield in EBUS-TBLB when PPLs≤20 mm.
ObjectiveTo investigate the anatomical characters of the sustentaculum tali (ST), accurate entry point and direction for the placement of ST screw from posterior subtalar joint facet to the constant fragment (CF) in calcaneal fractures.MethodsA total of 100 patients with calcaneal fractures performed ankle CT scans were enrolled between January 2016 and April 2016. According to the inclusion criteria, the clinical data of 33 patients were analyzed, including 18 males and 15 females, with a median age of 41.0 years (range, 18-60 years). There were 16 cases on left side and 17 cases on the right side. Three-dimensional (3D) calcaneal model was reconstructed by Mimics 17.0 software, and the ST anatomical references were measured, including the length of upper and lower edge, the length and height of the midline, the horizontal angle between the midline and foot plantar surface. The parameters of the optimal entry point position (P’ point) and placement angle of the ST screw were determined. The length of ST screw was also measured. The differences between males and females or left and right sides were compared.ResultsThe length of upper edge of the ST was (16.60±2.23) mm, lower edge (20.65±2.90) mm, midline (20.56±2.62) mm, and the height of midline was (9.61±1.36) mm. The horizontal angle between the midline and foot plantar surface was (23.43±3.36)°. The vertical distance from P’ point to the lowest point of the tarsal sinus was (3.09±1.65) mm, while the horizontal distance was (14.29±2.75) mm. The distance from P’ point to the apex of the lateral talus, subchondral bone of subtalar joint, calcaneocuboid joint was (11.41±3.22), (6.59±2.22), (34.58±3.75) mm, respectively. The horizontal angle between the ST screw and foot plantar surface was (–1.17±2.07)°. The anteversion angle of ST screw was (16.18±2.05)° and the length was (41.64 ± 3.09) mm. There were significant differences in the length of upper and lower edge, the length and height of the midline, the distance from P’ point to the apex of the lateral talus, subchondral bone of subtalar joint, and calcaneocuboid joint, and the anteversion angle and length of the ST screw between males and females (P<0.05). There was no significant difference in above all parameters between left and right sides (P>0.05).ConclusionAfter appropriate reduction of the calcaneal fractures, the entry point of ST screw was recommended at about 14 mm posterior and about 3 mm upper related to the foot horizontal line through the lowest tarsal sinus point; and the direction of ST screw placement was about 17° anteversion for males and 15° anteversion for females.
