ABSTRACT

Objective: To investigate the clinical value of the bipolar tweezers-clamp for the hepatic parenchymal transection in the resection of hepatocellular carcinoma. Methods: From January 2020 to January 2021,63 patients with the hepatocellular carcinoma for hepatectomy at Department of Hepatopancreatobiliary Surgery,Yuebei People's Hospital Affiliated to Shantou University Medical College were analyzed retrospectively.According to the different instruments used in the hepatic parenchymal transection,the patients were divided into bipolar tweezers-clamp group and ultrasonic scalpel group.There were 32 patients in bipolar tweezers-clamp group,with age of (55.5±10.5)years(range:37 to 78 years),including 22 males and 10 females,tumor size was (6.0±3.4)cm(range:2.4 to 13.4 cm). There were 6 patients with portal vein tumor thrombus and 5 patients with portal hypertension. There were 31 patients in ultrasonic scalpel group,with aged(57.8±10.1)years(range:37 to 79 years),including 27males and 4 females,tumor size was(7.9±5.1)cm(range: 2.4 to 21.3 cm),3 patients with portal vein tumor thrombus and 2 patients with portal hypertension. The preoperative baseline data,operation time,blood loss,postoperative liver function and the complications were compared between two groups using t test,χ2 test and Fisher exact probabilityrespectively. Results: The operation was successfully completed in both groups.Compared with the ultrasonic scalpel group,the operation time was significantly shorter((219.3±76.4)minutes vs.(294.0±100.8)minutes,t=-3.322,P=0.002),the blood loss was less((250(475)ml vs. 500(1 050)ml,t=-2.307,P=0.026),the concentrate red blood cells transfusion volume was less(0.92(0.88)U vs. 2.32(4.00)U,Z=-1.987,P=0.047) in the bipolar tweezers-clamp group.The postoperative serum ALB level was higher in the bipolar tweezers-clamp group than that in the ultrasonic scalpel group((33.5±6.1)g/L vs. (29.5±4.2)g/L,t=3.226,P=0.020) on postoperative day 1;((35.7±4.5)g/L vs.(30.1±3.2)g/L,t=5.575,P<0.01) on postoperative day 3;((33.2±3.7)g/L vs. (31.0±4.4)g/L,t=3.020,P=0.004) on postoperative day 7. There was no significant difference in serum ALT,TBIL and PT level between the two groups(all P>0.05).No postoperative bile leakage occurred in both groups.The postoperative complications occurred in 8 cases(25.0%)in the bipolar tweezers-clamp group,including liver failure in one,and in 11 cases(35.5%)in the ultrasonic scalpel group,including liver failure in two(P>0.05). Conclusion: The bipolar tweezers-clamp is a safe and reliable method for the hepatic parenchymal transaction,which is quick and less bleeding during the hepatic resection.

ABSTRACT

OBJECTIVES@#To investigate the genetic polymorphism of InDel loci in SifalnDel 45plex system in the Han population in Jiangsu Province and the Mongolian population in Inner Mongolia, and to evaluate the effectiveness of the system in forensic medicine.@*METHODS@#SifaInDel 45plex system was used for genotyping in blood samples of 398 unrelated individuals from the above two populations, and allele frequencies and population genetic parameters of the two populations were calculated respectively. Eight intercontinental populations in the gnomAD database were used as reference populations. The genetic distances between the two studied populations and eight reference populations were calculated based on the allele frequencies of 27 autosomal-InDels (A-InDels). The phylogenetic trees and multidimensional scaling (MDS) analysis diagrams were constructed accordingly.@*RESULTS@#Among two studied populations, the 27 A-InDels and 16 X-InDels showed no linkage disequilibrium between each other and the allele frequency distributions were in Hardy-Weinberg equilibrium. The CDP of the 27 A-InDels in two studied populations were all higher than 0.999 999 999 9, and the CPEtrio were all less than 0.999 9. The CDP of the 16 X-InDels in Han in Jiangsu and Mongolian in Inner Mongolia female and male samples were 0.999 997 962, 0.999 998 389, and 0.999 818 940, 0.999 856 063, respectively. The CMECtrio were all less than 0.999 9. The results of population genetics showed that the Jiangsu Han nationality, Inner Mongolia Mongolian nationality and East Asian population clustered into one branch, showing closer genetic relationship. The other 7 intercontinental populations clustered into another group. And the above 3 populations displayed distant genetic relationships with the other 7 intercontinental populations.@*CONCLUSIONS@#The InDels in the SifaInDel 45plex system have good genetic polymorphism in the two studied populations, which can be used for forensic individual identification or as an effective complement for paternity identification, and to distinguish different intercontinental populations.

ABSTRACT

PURPOSE@#To observe the changes of gait behavior and the expression of wound healing factors of transforming growth factor-β1 (TGF-β1), TGF-β3 and cAMP response element binding protein-1 (CREB-1) during the healing of Achilles tendon in a rat model, and to investigate whether gait analysis can be used to evaluate the tendon healing.@*METHODS@#Achilles tendon of 40 healthy male Sprague-Dawley rats were transected and sutured to establish the Achilles tendon injury (ATI) model. They were randomly divided into 4 groups based on the observational time point at 1, 2, 4 and 6 weeks after injury (n = 10 for each group). Before modeling, 9 rats were randomly selected for CatWalk gait analysis, which contained step cycle, single stance time and average speed. Data were recorded as the normal controls. After then, ATI models were established in the left hind limbs of the all 40 rats (ATI group), while the right hind limbs were only cut and sutured without injury of the Achilles tendon (sham operation group). At 1, 2, 4 and 6 weeks after injury, the gait behavior of the corresponding group of rats (n = 9) as observed and recorded by CatWalk platform. After then, the rats were sacrificed and Achilles tendon of both limbs was harvested. The tendon healing was observed by gross anatomy and histological examination, and the protein and mRNA expression of TGF-β1, TGF-β3, CREB-1 were observed by immunohistochemistry and qPCR. The results of tendon gross grading were analyzed by Wilcoxon rank sum test, and other data were analyzed by one-way analysis of variance among multiple groups.@*RESULTS@#Compared with normal controls, all gait indexes (step cycle, single stance time and average speed) were greatly affected following ATI, which however improved with time. The step cycle was significantly lower at 1, 2 and 4 weeks after ATI (compared with normal controls, all p  0.05). The single stance time of the ATI group was significantly shorter at 1 and 2 weeks after operation ((0.078 ± 0.010) s at 1 week, (0.078 ± 0.020) s at 2 weeks, all p < 0.001) and revealed no significant difference at 4 weeks (p = 0.120). The average speed of ATI group at 1, 2, 4, 6 weeks was significantly lower than that in the normal control group (all p < 0.001). Gross observation showed that the grade of local scar adhesion in ATI group increased significantly at 2, 4 and 6 weeks, compared with the sham operation group (all p < 0.001). Extensive adhesion was formed at 6 weeks after ATI. The results of HE staining showed that the number of fibroblast increased gradually and arranged more orderly in ATI group at 1, 2 and 4 weeks (all p < 0.001), and decreased at 6 weeks, but it was still significantly higher than that of the sham operation group (p < 0.001). Immunohistochemistry showed that the positive expression of TGF-β1, TGF-β3, CREB-1 in ATI group was higher than that in the sham operation group at 4 time points (all p < 0.05), which reached the peak at 2 weeks after operation and decreased at 4 weeks (p = 0.002, p < 0.001, p = 0.041, respectively). The results of qPCR suggested that the mRNA expression of TGF-β1, TGF-β3, CREB-1 in ATI group was higher than that in the sham operation group at all-time points (all p < 0.05), which reached the peak at 2 weeks after operation, decreased at 4 weeks, and significantly decreased at 6 weeks (all p < 0.001).@*CONCLUSION@#Gait behavior indexes are associated with Achilles tendon healing. The study gives an insight of TGF-β1, TGF-β3, CREB-1 changes in the coursing of Achilles tendon healing and these cytokines may be able to be used to regulate the Achilles tendon healing.

ABSTRACT

Chronic enteritis can produce an excess of reactive oxygen species resulting in cellular damage. Stanniocalcin-1(STC-1) reportedly possesses anti-oxidative activity, the aim of this study was to define more clearly the direct contribution of STC-1 to anti-oxidative stress in cattle. In this study, primary intestinal epithelial cells (IECs) were exposed to hydrogen peroxide (H2O2) for different time intervals to mimic chronic enteritis-induced cellular damage. Prior to treatment with 200 microM H2O2, the cells were transfected with a recombinant plasmid for 48 h to over-express STC-1. Acridine orange/ethidium bromide (AO/EB) double staining and trypan blue exclusion assays were then performed to measure cell viability and apoptosis of the cells, respectively. The expression of STC-1 and apoptosis-related proteins in the cells was monitored by real-time PCR and Western blotting. The results indicated that both STC-1 mRNA and protein expression levels positively correlated with the duration of H2O2 treatment. H2O2 damaged the bovine IECs in a time-dependent manner, and this effect was attenuated by STC-1 over-expression. Furthermore, over-expression of STC-1 up-regulated Bcl-2 protein expression and slightly down-regulated caspase-3 production in the damaged cells. Findings from this study suggested that STC-1 plays a protective role in intestinal cells through an antioxidant mechanism.

ABSTRACT

This study was purposed to investigate the expression of RPL36A (ribosomal protein 36a) in the newly diagnosed acute myeloid leukemia (AML) cells and its mechanism at the molecular level. The RPL36A mRNA expression in the newly diagnosed AML cells, U937 cells and normal MNCs was determined by RT-PCR. Small interfering RNA (siRNA) targeting to RPL36A was transfected into U937 cells by Lipofectamine 2000 system. Proliferation, cell cycle, apoptosis of U937 were observed through MTT assay, flow cytometry, acridine orange/ethidium bromide (AO/EB) double staining, TUNEL and Annexin V/FITC respectively. RPL36A mRNA and protein expression levels were detected by reverse transcriptase-polymerase chain reaction (RT-PCR) and Western blot analysis respectively. The results showed that RPL36A expression in the newly diagnosed AML cells and U937 cells was significantly upregulated. The average OD value of U937 cells transfected with RPL36A siRNA was significantly lower as compared with 3 control groups. The cell percentage in G2-and S-phase increased, which indicated the inhibition effect of RPL36A siRNA on cell proliferation. Remarkable cell apoptosis in U937 cells treated with RPL36A siRNA was observed by AO/EB, TUNEL analysis and Annexin V/FITC assay; RPL36A mRNA and protein expression level of U937 cells treated with siRNA were significantly declined in a time-dependent manner (r=0.9813 and 0.9537). It is concluded that the RPL36A expression in the AML cells is significantly enhanced and the RPL36A gene may be involved in regulation of cell cycle and cell apoptosis of AML, which promotes proliferation of AML cells and inhibits apoptosis of cells.

ABSTRACT

<p><b>BACKGROUND</b>Transcatheter Amplatzer occlusion of patent ductus artertiosus (PDA) has emerged as a minimally invasive alternative to surgical closure. The goal of this study was to compare long-term clinical outcomes between two procedures, especially on chronic residual shunt, late or very late procedure-related complications, and regression of pulmonary hypertension and left ventricular dilation.</p><p><b>METHODS</b>A total 255 patients having isolated PDA with a minimal diameter of >or= 4 mm treated from January 2000 to July 2003 were included in this study and have been followed up until July 2008. The patients were assigned to either the device or surgical closure group according to the patients' and/or their parents' preference. Baseline physical exams, chest roentgenography, electrocardiography, and echocardiography were performed preprocedure and at each follow-up.</p><p><b>RESULTS</b>Seventy-two patients accepted the transcatheter procedure (Group-TC) and 183 underwent surgical operation (Group-SO) for PDA closure, both groups were similar in their demographics and preoperative clinical characteristics. There were no cardiac deaths and late complications such as infectious endocarditis and Amplatzer duct occluder (ADO) dislodge in either group. More acute procedure-related complications were recorded in Group-SO (13.7%) compared with Group-TC (1.4%) (P = 0.004). The recovery time was (8.7 +/- 2.3) days for the Group-SO and (1.3 +/- 0.5) days for the Group-TC (P < 0.001). The survival freedom from persistent residual shunt, defined as residual shunt that can not resolve automatically, was 91.3% for Group-SO and 98.6% for Group-TC (P = 0.037 by Log-rank test). There was no significant difference in regression of pulmonary hypertension and left ventricular dilation; neither survival freedom from pulmonary hypertension nor abnormal left ventricular end-diastolic volume index were significantly different between the surgical group and the Amplatzer group.</p><p><b>CONCLUSIONS</b>Our study confirmed the long-term safety and efficacy of transcatheter Amplatzer occlusion. In comparison to the time-proven surgical closure, transcatheter Amplatzer occlusion was less invasive and associated with fewer complications and residual shunt, and as effective in the regression of pulmonary hypertension and left ventricular dilation.</p>

ABSTRACT

Objective To investigate the expression of NF-k B and c-myc in keratinocytes of HPV infected condyloma acuminata (CA) lesions.Methods Fifty cases of HPV 6/11 positive CA were diagnosed by in situ hybridization.The expression and distribution of NF-k B and c-myc were detected by immunohistochemistry technique (EnVision) with CA lesions and 25 normal human skins (foreskins). Results②The expression of NF-k B and c-myc was significantly higher in keratinocytes of CA lesions than those of normal controls (P<0.01 ).NF-k B was mainly expressed in spinous layers of CA lesions, and most positive signals located significantly in the cytoplasm.C-myc was mainly expressed in the whole epidermis or in spinous and basal layers in CA lesions,and positive signals located in the nuclei.②There was a positive correlation between the expression of NF-k B and c-myc in CA lesions (r=0.89,P<0.01).Conclusions The study demonstrates that the expression of both NF-k B and c-myc is significant- ly higher in HPV 6/11 positive CA than in normal skin.The data suggest that transcriptional factor NF-k B and c-myc may play a role in the regulation of proliferation of HPV 6/11 infected cells.
