Intrahepatic cholangiocarcinomas (ICCA) are primary intrahepatic malignancies originating from biliary epithelia.While both hepatocellular cancer and ICCA can present as mass lesions within the liver,these cancers are distinct in their morphology,etiology,pathology,natural history and response to therapy.There is a need for accurate and sensitive molecular markers for the diagnosis of ICCA.Recent advances in elucidating molecular and genetic characteristics of ICCA offer the potential of molecular-based diagnosis of ICCA.Specific genetic mutations of IDH1/2,BAP1,p53,and KRAS,FGFR gene fusions and alterations in microRNA have all been described in ICCA.Although there are no accurate serum or biliary biomarkers currently available for diagnosis of ICCA,several potential candidates have been identified.Knowledge of specific genetic or molecular abnormalities offers potential for individualized approaches for the treatment of patients with ICCA in the future.

Objective To estimate the quality and efficacy of the academic thesis of compound anisodine in traumatic optic neuropathies(TON)treatment. Method We searched Chinese database last or"blunt trauma"as key words,and analyzed them using the standard of evidence-based medicine(EBM).Result 6 RCTS with a total of 415 eyes included are retrieved,and the OR value is 6.54 with a 95%CI of[4.14,10.35],P＜0.00001,the difference is significant;sub-category analyses are made and both show significant difference(P＜0.0001). Conclusion The existing evidence supports that prognosis of TON is better when compound anisodine are adopt in treatment,and this effect is significant in steroid treatment.Compound anisodine can be used alone for TON treatment.However.because there are only 6 thesis are retrieved and all of them have methodological short-comings,the evidence is not convincing.There is an urgent need of well-planed,large-scale and multiple-center studies to assess the role of compound anisodine in traumatic optic neuropathies treatment.

Objective To investigate the major types and clinical manifestations of mitochondrial DNA (mtDNA)mutations in Chinese patients with Leber′s hereditary optic neuropathy(LHON). Methods A total of 119 patients with bilateral optic neuropathy from 117 pedigrees, including 37 with determinate diagnosis of LHON(group A) and 82 with suspected LHON(group B),were tested for mtDNA mutations by using single-strand conformational polymorphism, mutation-specific primer polymerase chain reaction and sequencing. Pertinent clinical data and history of the patients with the 11778 mutation were collected. Results Nucleotide positions(np)11778 mutation and np 14484 mutation was found in 33 (89.2%) and 3 (8.1%) patients respectively in group A, while np 11778 mutation was obtained in 26 (31.7%)in group B. No 3460 mutation was found in group A or B. The clinical manifestations of 59 patients with np 11778 mutation were as follows: acute or chronic visual loss,no ophthalmalgia, the age of onset of 10-25, and either a central or paracentral scotoma in perimetry. The visual recovery rate was 8.6%～11.6%. Conclusion Chinese patients with LHON have a very high incidence of np 11778 mutation and the clinical manifestations of the patients with np 11778 mutation are similar to those of Caucasian patients.

Objective:To analyze the characteristics and prognosis of visual field of Leber hereditary optic neuropathy (LHON) with G11778A mutation.Methods:A retrospective clinical study. Twenty-two (44 eyes) of LHON patients diagnosed with G11778A site mutation by mt-DNA examination from May 2008 to February 2018 in Ophthalmology Department of Dongfang Hospital of Beijing University of Chinese Medicine, were enrolled in this study. All patients underwent best corrected visual acuity (BCVA), visual field and optical coherence tomography (OCT). The BCVA examination was performed using the international standard visual acuity chart, which was converted into logarithm of the minimum angle of resolution (logMAR) BCVA for record. The thickness of the retinal nerve fiber layer (RNFL) in the 200μm×200μm annular region 1.73 mm outside the optic disc was measured by OCT. At least 7 visual field examinations were performed within one month before and after 2, 4, 8, 12, 18, 24 and 30 months of the course of disease by using Octopus 101 perimetry. Among 44 eyes, 27 eyes were detected with G2 procedure (G2 group) and 17 eyes were detected with LVC procedure (LVC group). The mean field defect (MD) and mean optical sensitivity (MS) were used as the main outcome indexes. According to the onset age, the patients were further divided into the ≤14 years old group and>14 years old group. There was a significant difference in initial logMAR BCVA between the G2 group and LVC group ( t=4.994, P=0.000), but there was no significant difference in gender ( χ2=1.896, P=0.169) and age ( t=0.337, P=0.708) between the two groups. Independent sample t test was used for comparison between groups, paired t test was used for comparison within groups, and one-way analysis of variance was used for comparison between groups. The statistical data were compared by χ2 test. Results:In the G2 group, the MD value of the subgroup of children (≤14 years old) decreased gradually during the follow-up period, and the MD value since 18 months after onset was significantly lower than the value of 2 months after onset ( t=3.813, 4.590, 5.033; P=0.002, 0.001, 0.000). No obvious visual field index changes were seen in other subgroups ( P>0.05). The central scotoma was the most common type of visual field defect in the early stage, and the diffuse defect was the most common type of visual field defect in the late stage. There was a significant difference in the types of visual field distribution between the early and late stage in G2 group ( χ2=17.414, P=0.015). There was no significant difference in the type of visual field distribution between the early and late stage in LVC group ( χ2=4.541, P=0.474). The MD value in the G2 group remained stable within 8 months after onset, but significantly improved after 18 months after onset ( t=2.100, 3.217, 3.566; P=0.046, 0.003, 0.001). The MS in the LVC group did not significantly improve during follow-up ( P>0.05). The average visual acuity of the G2 group was significantly improved from 12 months ( t=3.039, 3.678, 4.264, 5.078; P=0.008, 0.002, 0.001, 0.000). The visual acuity of the eyes in the G2 group was better than that of the LVC group during all follow-up periods ( P≤0.05). The RNFL thickness of all patients continued to decrease after onset, but the RNFL thickness was significantly higher at 4, 8, 18, 24, 30 months in the G2 group than those in the LVC group ( t=2.471, 2.269, 2.474, 2.509, 2.782; P=0.018, 0.028, 0.017, 0.016, 0.008). Conclusions:The main types of visual field defect of LHON with G11778A mutation are the central scotoma in the early stage, while the diffuse defect and central scotoma are both very common in the later stage. The visual field of LHON patients examined by G2 procedure is significantly improved during the follow-up, as well as the visual acuity improved significantly, and the visual field improvement in younger cases (≤14 years old) is better than that of older cases (>14 years old), but the visual field of the LVC procedure cases did not improve during follow-up.

Objective To explore the value of IFN-γ produced or secreted by CD+4 T Lymphocytes from pleural effusion mononuclear cells for the diagnosis of tuberculous pleurisy(plTB).Methods The PEMCs of 40 patients with tuberculous pleural effusion and 30 patients with malignancy pleural effusion were selected as the tuberculosis and disease control groups, then co-cultured with the early secretory antigenic target 6 (ESAT-6) and culture filtered protein 10 (CFP-10) fusion protein (E/C).The numbers of spot forming cells(SFC) secreting IFN-γ were enumerated by ELISpot and the ratios of cells producing IFN-γ were detected by flow cytometry and intracellular cytokine staining.Moreover, the two indicators were compared between tuberculosis and disease control groups to evaluate the 2 methods detecting IFN-γ in the diagnosis of plTB.Results After E/C stimulation, the numbers of SFC were 205(125-450)SFC/5×104 PEMC in tuberculosis group and 5(2-18)SFC/5×104 PEMC in disease control group by ELISpot.The difference between two groups was statistically significant (U= 20.00, P<0.01).The proportion of IFN-γ-secreting CD+4 T lymphocytes was 3.27% (1.81%-7.34%) in tuberculosis group and 0.12% (0.06%-0.46%) in control group detected by FCM. The difference between the two groups was statistically significant (U=45.00, P<0.01).The indicators of ELISpot in detection of IFN-γ which was secreted by PEMC after co-cultured with E/C were as follows: sensitivity 92.5% (37/40), specificity 80.0% (24/30), positive predictive value 0.86, negative predictive value 0.89, positive likelihood ratio 4.63, negative likelihood ratio 0.09 and accuracy 87.1%;and for FCM, they were 87.5% (35/40), 90.0% (27/30), 0.92, 0.84, 8.75 and 0.14, respectively and accuracy 88.6%.Conclusion After E/C stimulation, the assay for IFN-γ-secreting CD+4 T lymphocytes by FCM and ELISpot is highly sensitive and specific for diagnosis of plTB as an auxiliary method.

Objective Toinvestigatetheimpactofthedifferentrupturepoints(sac,neck,andtop) of intraoperative aneurysm rupture (IAR)on the prognosis of patients in anterior circulation aneurysm clipping.Methods Theclinicaldataof135consecutivepatients(148aneurysms)acceptedmicrosurgical aneurysm clipping from May 2009 to March 2012 were analyzed retrospectively. The prognostic evaluation of the patients after procedure was assessed by using the Glasgow outcome scale (GOS). The different aneurysm rupture points of IAR were used as influencing factors,and the relationship between the different rupture pointsandtheprognosisofpatientswasanalyzed.Results Duringclippingof148aneurysmsin 135 patients,31 aneurysms in 30 patients had intraoperative rupture (20. 9% of the aneurysms, 22.2% of the patients). Nine rupture points occurred on the top of aneurysms,17 occurred on the sac,and 5 occurred on neck. The Glasgow outcome scale (GOS)scores 5,4,3,2 and 1 were in 17,8,2,1 and 2 patients,respectively. A total of 25 patients had good prognosis and 5 cases had poor prognosis. There were no significant differences in the impact of different rupture points of IAR on the prognosis in patients of IAR (OR,100. 00,95% confidence interval 6. 764-18. 344,P=0. 006). Of the 25 patients with aneurysm sac or top rupture,1 case had poor prognosis. Of the 5 patients with aneurysm neck rupture, 4caseshadpoorprognosis.Conclusion Inanteriorcirculationaneurysmclipping,thedifferent aneurysm rupture points may have significant impact on the prognosis of patients,the aneurysm neck rupture is a main factor for resulting in the poor prognosis of patients.

BacKground:The deveIopment of acute pancreatitis( AP ) is often accompanied by pancreatic microcircuIation disturbance and aIterations in bIood coaguIation and fibrinoIytic systems, which resuIts in abnormaIities of pIateIet parameters. Aims:To investigate the changes of pIateIet parameters in eIderIy AP patients and the effect of uIinastatin ( UTI)on pIateIet parameters and disease status. Methods:Two hundred and seventeen eIderIy AP patients(≥60 years) were enroIIed retrospectiveIy from Aug. 2009 to Dec. 2013 at the First AffiIiated HospitaI of Nanjing MedicaI University. According to the severity of the disease,patients were divided into three groups:miId AP( MAP),moderateIy severe AP ( MSAP),and severe AP( SAP). The pIateIet parameters,incIuding PLT,MPV and PDW before and after treatment,as weII as the differences in pIateIet parameters and cIinicaI efficacy between conventionaI therapy and UTI therapy were compared and anaIyzed. Results:In MSAP and SAP groups,PLT at admission was significantIy Iower(P<0. 01),whiIe MPV and PDW were significantIy higher(P<0. 05)than those in MAP group. After 1-week treatment,PLT increased significantIy(P<0. 01)and MPV and PDW decreased significantIy(P<0. 05)in MSAP and SAP groups. UTI therapy was superior to conventionaI therapy in increasing PLT( P <0. 01 ),decreasing MPV and PDW( P <0. 01 ),and improving the overaII efficacy in MSAP and SAP groups( MSAP:92. 3% vs. 81. 2%,P <0. 01;SAP:90. 0% vs. 80. 8%,P<0. 01). Conclusions:Changes of pIateIet parameters in eIderIy MSAP and SAP patients are different from those in MAP patients,which might refIect the disease severity. UTI is effective in reducing the activity of pIateIet and can be used in the treatment and prevention of disease progression in eIderIy AP patients.

Objective To evaluate the clinical value of the real-time three-dimensional ultrasound in the diagnosis of the fistula-in-ano.Methods One hundred and eighteen fistula-in-ano patients were examined using conventional and three-dimensional ultrasound,the stereotaxis of interal opening and the shape of the fistula-in-ano were analyzed.Then the diagnosis results of ultrasound were compared with the surgery and pathology.Results In 1 1 8 patients,the accuracy of preoperative identifying internal opening by two-dimensional ultrasound was 85%,and 95% for three-dimensional ultrasound with statistically significant difference (χ2 =6.679,P <0.05).For complex anal fistula,the diagnostic accuracy rates of main fistula tract by three-dimensional ultrasound (100%,82/82 )was higher than that by two-dimensional ultrasound(95%,78/82),the difference was statistically significant (χ2 =4.100,P <0.05 ).In 82 cases of complex anal fistula,the diagnostic accuracy of branch fistula tract by two-dimensional ultrasound was 70%(57/82 ),the accuracy using three-dimensional ultrasound was 89% (73/82 ),there was statistically significance (χ2 =9.499,P < 0.05 ).Conclusions Three-dimensional ultrasound can accurately locate the interal opening of fistula-in-ano and determine the shape of fistula-in-ano,which provided the most intuitive information for clinical treatment and had high practical value.

Objective:To evaluate the efficacy and safety of compound anisodine (CA) injection for anterior ischemic optic neuropathy (AION).Methods:Studies, which were randomized controlled trials (RCT) of CA with routine treatment for AION from PubMed, The Cochrane Library, Web of Science, CNKI, Wanfang database, Chinese science and technology journals full-text database and CD-ROM database of Chinese Biology Medical disc published from January 1978 to June 2021 were searched.Included studies were screened by two researchers independently based on inclusion and exclusion criteria.After data collection and quality assessment, a meta-analysis of included studies was performed with Revman 5.3 software.Results:Thirteen RCT were included, involving 1 636 eyes, with 829 eyes in treatment group and 807 eyes in control group without CA treatment.It was found that the total effective rate of treatment group was higher than that of control group ( OR=3.25, 95% CI: 2.47-4.28, P<0.01), and the best corrected visual acuity of AION patients after CA treatment was significantly better than that of control group when articles with high heterogeneity were excluded (MD=0.14, 95% CI: 0.11-0.17, P<0.01) or not (MD=0.14, 95% CI: 0.12-0.16, P<0.01).The mean defect of visual field was significantly smaller and the mean sensitivity of visual field was higher in treatment group than control group (MD=-2.58, 95% CI: -3.98--1.19, P<0.01; MD=3.49, 95% CI: 3.07-3.91, P<0.01). Conclusions:CA shows good efficacy in the treatment of AION.It can improve visual acuity and mean sensitivity of visual field, decrease mean defect of visual field.
