Background Behcet's disease is a refractory panuveitis with high blindness rate.Multifocal electroretinography (mfERG) is a useful tool for the evaluation of the function of the posterior retina.ObjectiveThe aim of this study is to assess the characteristics of Behcet's disease using the mfERG.Methods mfERG was recorded in 68 eyes of 39 cases with active stage of Behcet's disease.All of the patients were diagnosed based on the Standard of International Study Group for Behcet's Disease and assigned to the cystoid macular edema (CME) group and the diffuse macular edema (DME) group after assessment by fundus fluorescein angiography (FFA).Seventeen normal subjects were used as controls.Oral informed consent was obtained from all of the subjects prior to this trial.mfERG recording followed the ISCEV Guidelines for Clinical Multifocal Electroretinography (2007 edition).The response density and latency of P1 and N1 waves in 6 rings were analyzed and compared.Results The amplitudes of N_1 waves from rings 1 through 6 and N1 wave from rings 1 through 5 were significantly declined in patients with Behcet's disease compared with normal control (P＜0.01).All of the latencies of P_1 waves from rings 1 through 6 were insignificantly shortened in patients with Behcet's disease compared with normal control (P＞0.05).The amplitudes of P_1 and N_1 waves from rings 1 through 6 in diffuse macular edema group were considerably lower than those in the cystoid macular edema group (P＜0.05,P＜0.01).A test of visual acuity showed a negative correlation to the amplitude and latency of N_1 wave (r=-0.36,-0.37,P＜0.05 ) and a positive correlation with the amplitude of N1 wave (r=0.43,P＜0.05) in the DME group.In the CME group,a test of visual acuity presented a negative correlation to the amplitude and latency of N1 wave and latency of P1 (r=-0.41,-0.35,-0.40,P＜0.05 ) and a positive correlation with the amplitude of P1 wave (r=0.48,P＜0.05).Conclusion mfEGR demonstrates that retinal electro-activity is abnormal in eyes with Behcet's disease.The distinct functional disorder is situated around the fovea.

Objective:To investigate the safety and efficacy of early oral feeding in the treatment of mild acute pancreatitis (MAP).Methods:Data of 100 MAP patients from April 2015 to June 2018 admitted in Department of General Surgery in Shanxi Bethune Hospital were collected. According to the time of food intake through the mouth, the patients were divided into early oral feeding group (food intake started when the symptoms of abdominal pain and abdominal distension were alleviated with gastrointestinal functional recovery, but serum amylase and lipase did not decrease to a level below 2 times of normal upper limits) and traditional oral feeding group (food intake started when the symptoms of abdominal pain and abdominal distension were alleviated with gastrointestinal functional recovery, but serum amylase and lipase decreased to a level below 2 times of normal upper limits), with 50 cases in each group. The incidence of abdominal pain or bloating, serum amylase, CRP, organ dysfunction, morbidity and mortality, and median length of hospital stay after eating were compared between the two groups.Results:There were no statistically significant differences on gender, age, etiology, abdominal pain and distension, increased serum amylase, increased blood CRP, and number of organ dysfunction cases between two groups, and there were no deaths in either group. However, the feeding time and length of hospital stay in the early oral feeding group were significantly shorter than those in the traditional oral feeding group, and the differences were statistically significant [(3.00±0.18)d versus (4.84±0.27)d, (8.24±0.33) D versus (9.00±0.26)d, both P<0.05]. Conclusions:Early oral feeding in MAP patients did not aggravate the disease, but helps to correct the nutritional status of the patients, with higher safety and effectiveness.

Objective:To compare the clinical effectiveness of laparoscopic cholecystectomy (LC)+ laparoscopic choledocholithotomy (LCBDE)+ one-stage suture and primary choledocholithotomy with endoscopic retrograde cholangiopancreatography (ERCP)+ endoscopic duodenal sphincterotomy (EST)+ nasobiliary drainage (ENBD)+ LC in the treatment of choledocholithiasis complicated with gallbladder stones.Methods:A total of 200 patients with choledocholithiasis complicated with gallbladder stones admitted to the General Surgery Department of Shanxi Bethune Hospital from June 2015 to February 2021 were collected, and patients were divided into LC+ LCBDE+ one-stage suture (one-stage suture group, n=130) and ERCP+ EST+ ENBD+ LC (endoscopic surgery group, n=70) according to different treatments. The amount of intraoperative blood loss, operation time, postoperative feeding time, postoperative incidence of pancreatitis, cholangitis and other complications (biliary leakage, abdominal bleeding, wound infection), hospitalization costs, postoperative hospital stay, etc were compared between two groups. Results:The postoperative incidence of pancreatitis in the one-stage suture group (0.7% vs 5.7%) and the hospitalization cost [(2.74±0.39) ten thousand yuan vs (3.86±0.63) ten thousand yuan] were significantly lower than those in the endoscopic surgery group. The operation time [(103.21±9.36) min vs (88.18±7.20)min] was significantly longer than that of the endoscopic surgery group, and postoperative feeding time [(3.3±0.3)d vs (2.2±0.8)d] were significantly later than the endoscopic surgery group ( P<0.05). The amount of intraoperative blood loss [(36.0±3.0)ml vs (37.3±2.7)ml], the incidence of postoperative cholangitis (1.5% vs 2.9%) and other complications [biliary leakage (2.3% vs 1.4%), abdominal bleeding (1.5% vs 4.3%), wound infection(0 vs 0)], postoperative hospital stay [(6.8±1.3)d vs (7.1)d] had no significant differences between the two group. Conclusions:The two minimally invasive methods for the treatment of choledocholithiasis complicated with gallbladder stones had good efficacy, but LC+ LCBDE+ one-stage suture can retain the sphincter function of Oddis, maintain the normal anatomy and physiology of the biliary tract, reduce the incidence of related complications, and contribute to the recovery of patients, with high safety, effectiveness and feasibility.

OBJECTIVETo study the change of WT1 gene expression during human leukemic K562 cell differentiation and apoptosis induced by bufalin.

METHODSCell viability was determined by trypan blue exclusion, cell differentiation and apoptosis by nitro blue tetrazolium (NBT) reduction test, morphology and flow cytometry, expression of WT1 protein by Western blot analysis, and expression of WT1 mRNA by reverse transcriptase-polymerase chain reaction (RT-PCR).

RESULTS(1) The cell proliferation was inhibited by bufalin and the IC(50) at 24, 48, 72 h were 0.026, 0.032 and 0.006 micro mol/L, respectively. (2) Bufalin induced K562 cell differentiation towards macrophage/monocyte within concentration from 0.01 to 0.05 micro mol/L and apoptosis at higher than 0.026 micro mol/L. (3) The expression of WT1 protein and mRNA were downregulated by bufalin in the initial stage of differentiation and apoptosis induced by bufalin.

CONCLUSIONK562 cell differentiation and apoptosis induced by bufalin might relate to the downregulation of WT1 expression.

Objective To analyze the clinical outcomes of a standard protocol of open reduction and internal fixation using a variable angle foot plate for a consecutive series of patients with acute Lisfranc joint injury.Methods This study retrospectively evaluated the clinical outcomes of 11 Chinese patients(13 feet) with acute Lisfranc joint injury who had been treated by open reduction and internal fixation with a variable angle foot plate from December 2016 to June 2017 at Department of Orthopaedics,West China Hospital.They were 8 men(10 feet) and 3 women(3 feet),aged from 19 to 57 years(average,36.4 years).Of them,10 were complicated with fracture of metatarsus,6 with cuneiform fracture and/or dislocation,4 with cuboid fracture,and one with cuboid fracture.According to the Myerson classification for Lisfranc fracture-dislocations,one case(one foot) belonged to type A,2(2 feet) to type Bl,5(6 feet) to type B2,2(3 feet) to type Cl and one(one foot) to type C2.The outcomes were evaluated using the visual analogue scale(VAS) and the midfoot scores of American Orthopedic Foot and Ankle Society(AOFAS).Results This cohort was followed up for 18 to 24 months(average,22 months).Their VAS scores were decreased significantly from preoperative 7.3±1.2(from 6 to 9) to postoperative 1.2±0.2(from 0 to 2)(P<0.05);their AOFAS midfoot scores were increased significantly from preoperative 0 to postoperative 84.6±4.6(P<0.05) Anatomic reduction was obtained in all the patients and all the fractures united successfully without any delayed union or nonunion.Superficial necrosis of the wound edge occurred in 2 cases without deep infection;skin anesthesia occurred in 2 and skin hypesthesia in 4,indicating a lesion of the superficial peroneal nerve.Conclusion Fixation of acute Lisfranc joint injury with a variable angle foot plate can lead to rigid stability,precise reduction and satisfactory short-term clinical outcomes.

Cryoablation therapy with explicit anti-tumor mechanisms and histopathological manifestations has a long history.A large number of clinical practice has shown that cryoablation therapy is safe and effective,making it an ideal tumor treatment method in theory.Previously,its efficacy and clinical application were constrained by the limitations of refrigerants and refrigeration equipment.With the development of the new generation of cryoablation equipment represented by argon helium knives,significant progress has been made in refrigeration efficien-cy,ablation range,and precise temperature measurement,greatly promoting the progression of tumor cryoablation technology.This consensus systematically summarizes the mechanism of cryoablation technology,indications for oral mucosal melanoma(OMM)cryotherapy,clinical treatment process,adverse reactions and management,cryotherapy combination therapy,etc.,aiming to provide reference for carrying out the standardized cryoablation therapy of OMM.

TCP family as plant specific transcription factor, plays an important role in different aspects of plant development. In order to screen TCP family members in tobacco, the homologous sequences of tobacco and Arabidopsis TCP family were identified by genome-wide homologous alignment. The physicochemical properties, phylogenetic relationships and cis-acting elements were analyzed by bioinformatics. The homologous genes of AtTCP3/AtTCP4 were screened, and RT-qPCR was used to detect the changes of gene expression upon 20% PEG6000 treatment. The results show that tobacco contains 63 TCP family members. Their amino acid sequence length ranged from 89 aa to 596 aa, and their protein hydropathicity grand average of hydropathicity (GRAVY) ranged from -1.147 to 0.125. The isoelectric point (pI) ranges from 4.42 to 9.94, the number of introns is 0 to 3, and the subcellular location is all located in the nucleus. The results of conserved domain and phylogenetic relationship analysis showed that the tobacco TCP family can be divided into PCF, CIN and CYC/TB1 subfamilies, and each subfamily has a stable sequence. The results of cis-acting elements in gene promoter region showed that TCP family genes contain low docile acting elements (LTR) and a variety of stress and metabolic regulation related elements (MYB, MYC). Analysis of gene expression patterns showed that AtTCP3/AtTCP4 homologous genes (NtTCP6, NtTCP28, NtTCP30, NtTCP33, NtTCP42, NtTCP57, NtTCP63) accounted for 20% PEG6000 treatment significantly up-regulated/down-regulated expression, and NtTCP30 and NtTCP57 genes were selected as candidate genes in response to drought. The results of this study analyzed the TCP family in the tobacco genome and provided candidate genes for the study of drought-resistance gene function and variety breeding in tobacco.
