ABSTRACT
Background/Aims@#This study aimed to investigate the biological function and regulatory mechanism of TCN1 in colorectal cancer (CRC). @*Methods@#We studied the biological function of TCN1 by performing gain-of-function and loss-offunction analyses in HCT116 cell lines; examined the effects of TCN1 on the proliferation, apoptosis, and invasion of CRC cells; and determined potential molecular mechanisms using HCT116 and SW480 CRC lines and mouse xenotransplantation models. Tumor xenograft and colonization assays were performed to detect the tumorigenicity and metastatic foci of cells in vivo. @*Results@#TCN1 knockdown attenuated CRC cell proliferation and invasion and promoted cell apoptosis. Overexpression of TCN1 yielded the opposite effects. In addition, TCN1-knockdown HCT116 cells failed to form metastatic foci in the peritoneum after intravenous injection. Molecular mechanism analyses showed that TCN1 interacted with integrin subunit β4 (ITGB4) to positively regulate the expression of ITGB4. TCN1 knockdown promoted the degradation of ITGB4 and increased the instability of ITGB4 and filamin A. Downregulation of ITGB4 at the protein level resulted in the disassociation of the ITGB4/plectin complex, leading to cytoskeletal damage. @*Conclusions@#TCN1 might play an oncogenic role in CRC by regulating the ITGB4 signaling pathway.
ABSTRACT
Objective:To investigate the RHD genotypes of RhD-negative pregnant women and explore the optimum strategy for fetal RHD screening among this population in the region. Methods:This prospective study recruited 33 cases of RhD-negative singleton pregnancies at ≥12 weeks of gestation in Nanjing Drum Tower Hospital from March to November 2021. On the basis of RHD genotyping, quantitative real-time polymerase chain reaction (PCR) was used to amplify the exons 5 and 10 of RHD gene in the circulating cell-free DNA of RhD-negative pregnant women harboring whole RHD gene deletion and RHD-CE(2-9)- D. High-throughput sequencing was performed to detect chr1:25648453 locus from circulating cell-free DNA in plasma of RhD-negative pregnant women harboring RHD 1227A mutation to screen the fetal RhD blood group. Neonatal umbilical cord blood samples were collected for verifying fetal RHD genotyping. Descriptive statistical analysis was used. Results:Whole RHD gene deletion homozygous genotype ( n=20, 60.6%), RHD-CE(2-9) -D/whole RHD gene deletion heterozygous genotype ( n=5, 21.2%), RHD 1227A/whole RHD gene deletion heterozygous genotype ( n=7, 15.2%) and RHD 711delC/whole RHD gene deletion heterozygous genotype ( n=1) were identified in the 33 RhD-negative pregnant women. In the 25 cases with whole RHD gene deletion homozygous genotype or RHD-CE(2-9)- D/whole RHD gene deletion heterozygous genotype, 22 fetuses were RhD-positive and three were RhD-negative based on prenatal screening, which were confirmed by the neonatal serological test results after birth. In the seven cases carrying RHD 1227A/whole RHD gene deletion heterozygous genotype, all fetuses were RhD-positive, which were consistent with the results of serological detection after delivery. The case harboring RHD 711delC/whole RHD gene deletion heterozygous genotype did not receive fetal RHD screening. Conclusions:This study suggests that whole RHD gene deletion homozygous genotype is the most common allele in RhD-negative population in this area, followed by RHD 1227A/whole RHD gene deletion heterozygous genotype and RHD- CE(2-9)- D/whole RHD gene deletion heterozygous genotype. For women with whole RHD gene deletion homozygous genotype, RHD- CE(2-9)- D, or RHD 1227A mutation, fetal RHD screening with quantitative real-time PCR and high-throughput sequencing are important for the management of RhD-negative pregnant women.

The main treatment disciplines were vascular surgery (14 times), plastic surgery (3 times), and cardiology (2 times).Conclusion:For the diagnosis and treatment of diabetic foot, it is necessary to set up a multidisciplinary team as early as possible to control the causes of diabetic foot ulcer, prevent the recurrence of diabetic foot ulcer, reduce the mortality and amputation rate, and improve the quality of life of patients.
ABSTRACT
In order to explore the treatment of Her-2 positive breast cancer patients who failed in multi-line treatments, we retrospectively analyzed the clinical data of a patient with refractory Her-2 positive breast cancer.The patient was initially diagnosed as Her-2 positive advanced breast cancer.After six line treatment in the outer hospital, the patient′s condition was basically in a progressive state.The breast tumor was broken and purulent, the lung metastasis increased, and the patient′s quality of life was poor.The patient was admitted to Department of Breast Surgery of Affiliated Suqian Hospital of Xuzhou Medical University, after MDT discussion, we gave pyrrolotinib combined with capecitabine treatment, the chest wound healed gradually, the lung metastasis gradually reduced, and the quality of life was better.A retrospective analysis of this case showed that pyrrolidine combined with capecitabine may bring hope to Her-2 positive breast cancer patients who failed to receive multi-line therapies, especially those who failed to target therapy.
ABSTRACT
Background/Aims@#Colorectal cancer (CRC) patients often exhibit peritoneal metastasis, which negatively impacts their prognosis. CD31 and D2-40 have recently been suggested to be predictors of breast cancer prognosis, but their role in colorectal peritoneal metastasis (CRPM) remains unknown. @*Methods@#The expression profiles of CD31 and D2-40 were analyzed in CRC patients with or without CRPM and in CRC cell lines with increasing metastatic potential. Overexpression and short hairpin RNA knockdown assays were performed in CRC cells, and the effects of these alterations on epithelial-mesenchymal transition (EMT) in vitro, growth of xenograft tumors in vivo, and peritoneal metastasis potential in a mouse model of CRPM were examined. @*Results@#The expressions of CD31 and D2-40 were upregulated in CRC tumor tissues and was elevated further in tumor tissues from patients with CRPM. CD31 and D2-40 expression levels exhibited increasing trends parallel to the EMT potential of CRC cells. CD31 and D2-40 are essential for CRC cell EMT in vitro as well as for xenograft tumor growth and peritoneal metastasis in vivo. @*Conclusions@#CD31 and D2-40 contribute to CRPM by promoting EMT and may serve as prognostic markers and therapeutic targets for CRC, particularly in patients with peritoneal metastasis.
ABSTRACT
Objective To evaluate the clinical efficacy of percutaneous transluminal angioplasty (PTA) combined with stent implantation in the treatment of transplant renal artery stenosis (TRAS) after renal transplantation. Methods Clinical data of 21 patients with TRAS after renal transplantation undergoing PTA combined with stent implantation were retrospectively analyzed. The incidence of TRAS in renal transplant recipients was summarized. The changes of relevant indexes in patients with TRAS were statistically compared before and after interventional treatment. Clinical prognosis of patients with TRAS was evaluated. Results The incidence of TRAS in renal transplant recipients was 4.1%(21/507). TRAS was diagnosed at postoperative 5 (4, 7) months, and 67% (14/21) of patients developed TRAS within postoperative 6 months. Compared with the values before interventional therapy, the serum creatinine level, systolic and diastolic blood pressure and peak flow velocity of transplant renal artery of patients with TRAS were significantly decreased, and the estimated glomerular filtration rate (eGFR) and interlobar arterial resistance index were significantly increased at 1 week and 1 month after interventional therapy (all P < 0.05). During postoperative follow-up after PTA combined with stent implantation, 1 patient suffered re-stenosis of the transplant renal artery, which was improved after simple balloon dilatation. One patient developed pseudoaneurysm formation at the puncture site of the right femoral artery. One patient presented with renal atrophy and loss of function due to atresia of the transplant renal artery. All the remaining 18 patients were well recovered after surgery. Conclusions PTA combined with stent implantation is the optimal treatment of TRAS after renal transplantation, which can significantly improve the function of transplant kidney and considerably prolong the survival time of transplant kidney.
ABSTRACT
Objective@#To explore the effect of lipopolysaccharide intervention program on Legionella pneumonia.@*Methods@#C3H/HeN mice (6-8 weeks old) were used as experimental animals. The mice were randomly divided into lipopolysaccharide intervention, non-lipopolysaccharide intervention and control groups. Each group was again divided into three time points: 12 h, 24 h and 48 h. Mice in the lipopolysaccharide intervention group were intraperitoneally injected with E. coli lipopolysaccharide (100 ng per mice), and the rest groups were intraperitoneally injected with normal saline. After 24 hours, mice in the lipopolysaccharide intervention and the non-intervention groups mice were infected with Legionella by tracheal injection and the control group was given the same amount of saline. All the mice were killed at 12, 24 and 48 hours respectively. The mice were anatomized, lungs of the mice were separated and weighed. Organ coefficients (lung weight/body weight of mice) were calculated. 1 ml Orbital blood was collected. Toll-like receptor 4 (TLR4) levels of peripheral blood mononuclear cells were measured by flow cytometry. The contents of TNF-α and IL-1β in the upper left lung lobe were measured by ELISA.@*Results@#In the lung organs, the coefficients of lipopolysaccharide non-intervention group were higher than the other groups and there was no significant difference seen between the lipopolysaccharide intervention group and the controls. TLR4 peaked at 12 hours in both the lipopolysaccharide intervention and the non-intervention groups while the TLR4 level in the intervention group was higher than that in the non-intervention group. There were no significant differences appeared on the TLR4 expression levels between the two Legionella pneumonia modelled groups at 24 or 48 hours. There was no significant difference seen regarding the concentration of TNF-α and IL-1β between the intervention and the control groups. The secretion levels of TNF-α and IL-1β in the non-intervention group were higher than those in the intervention group at each time point.@*Conclusion@#The lipopolysaccharide intervention program may alleviate the inflammatory symptoms of Legionella infection.
ABSTRACT
Objective To explore the relationship between the status of HBsAg-positive infection of mothers and the non/low-response to hepatitis B vaccine of their infants.Methods A total of 225 pairs of mothers and their infants were recruited in our cohort from June 2011 to July 2013.Infants were given three doses of hepatitis B vaccine at hour 24,first month and month 6th respectively and were followed up for one year after birth.HBV serological markers and HBV DNA in the peripheral blood of both mothers and infants were detected by Electro-chemiluminescence immunoassay and fluorescence quantitative Polymerase Chain Reaction.Results Six HBV infection models were detected in HBsAg-positive mothers,and "HBsAg (+),HBeAg (+),anti-HBc (+)" (model one) and "HBsAg (+),anti-HBe (+),anti-HBc (+)" (model two) accounted for 92.5％ (208/225) of all the models.Rate of non/low-response to hepatitis B vaccine in infants born to mothers in model one was lower than those in model two,the differences are statistically significant (x2=4.80,P=0.029).The rate of non/low-response to hepatitis B vaccine in infants showed a downward trend with the rising of HBeAg level in their mothers (x2=4.86,P=0.028).Results from the unconditional logistic regression analysis showed that the HBeAg of the HBsAg-positive mothers was significantly correlated with the low risk of non/low-response to hepatitis B vaccine in infants (OR=0.598,95％CI:0.378-0.947).The positive rate of serum HBV DNA in HBsAg-positive mothers was 54.2％,while the rate of non/low-response to hepatitis B vaccine in infants born to HBV DNA positive mothers was similar to those infants born to HBV DNA negative mothers (X2=0.22,P=0.640).Conclusions "HBsAg (+),HBeAg (+),anti-HBc (+)" and "HBsAg (+),anti-HBe(+),anti-HBc (+)" were the common models seen in HBsAg-positive mothers,and the rate of non/low-response to hepatitis B vaccine was different between the two models.HBeAg of HBsAg-positive mothers might have positive effects on the immune response to hepatitis B vaccine in infants but the mechanisms remained not clear.HBV DNA of the HBsAg-positive mothers did not seem to be correlated with the immune response to hepatitis B vaccine in infants.

ABSTRACT
Objective To explore the relationship between HBeAg in HBsAg positive mothers and CD4 + CD25 + Foxp3 + regulatory T cells (Treg) in newborns,as well as how they would influence the increasing risk on HBV intrauterine transmission.Methods We collected information on general demographic characteristics and delivery on 270 HBsAg positive mothers and their newborns from the Third People's Hospital of Taiyuan.Fluorescence quantitative polymerase chain reaction (FQ-PCR) and chemiluminescence immunoassay (CLIA) were used to detect HBV DNA and HBV serological markers in peripheral blood from both mothers and neonates.The expression of Treg and other immune cells in peripheral blood of neonates were detected with flow cytometry (FCM).Results Maternal HBeAg positive rates were associated with an increased risk of intrauterine transmission (0R=4.08,95％ CI:1.89-8.82).Rates of T.reg in newborns born to HBsAg-positive mothers were higher than that of the negative group (Z=2.29,P=0.022).Each pair of the subjects was assigned to five different groups according to the HBeAg titers of mothers.Frequencies of both Treg and HBeAg in newboms and HBV DNA in mothers between the above said 5 groups showed similar trends of changing patterns and the differences between groups were statistically significant (x2=18.73,P＜0.001;x2=181.60,P＜0.001;x2=183.09,P＜0.001).Results from partial correlation analysis showed that after adjusting for neonatal HBeAg and maternal HBV DNA,mother's HBeAg titers were positively related to the percentage of Treg in their newboms (rs=0.19,P=0.039).In addition,the frequencies of Treg were negatively correlated with pDC and CD4 + T cell in their newborns (rs=-0.21,P=0.017;r,=-0.23,P=0.009).Conclusion HBeAg from HBsAg positive mothers might have inhibited the function of neonatal DC cells and T cells to reduce the immune response to HBV by up-regulating the proportion of Treg and finally increased the risk of HBV intrauterine transmission.
ABSTRACT
Objective To explore the effect of interleukin-6 (IL-6) and Interleukin-12(IL-12) on immune response to hepatitis B vaccination in infants of HBsAg-positive mothers.Methods A total of 91 neonates whose mothers were HBsAg-positive were included and followed up for 12 months.HBV DNA and HBV serological markers in the peripheral blood of the neonates and infants were detected with fluorescence quantitative polymerase chain reaction (FQ-PCR) and chemiluminescence immunoassay (CLIA),and the levels of IL-6 and IL-12 in the peripheral blood of the neonates and infants were detected with enzyme-linked immunosorbent assay (ELISA).Results The non-/hypo-response rate to hepatitis B vaccination was 35.16％ (32/91) in the 91 infants.In the neonatal period and infantile period,the level of IL-6 in non-/hypo-response group was lower than that in high-response group,while the level of IL-12 was higher than that in high-response group,and there was significant difference (P＜0.01).From the neonatal period to the infantile period,the level of IL-6 increased,while the level of IL-12 descended in both groups,and there was significant difference (P＜0.01).Furthermore,the level of anti-HBs of infants was positively correlated with the level of IL-6 (rs =0.70,0.79,P＜ 0.01),and was negatively correlated with the level of IL-12 (rs=-0.71,-0.72,P＜0.01) in the neonatal period and the infantile period.From the neonatal period to the infantile period,the increased level of IL-6 was positively associated with the level of anti-HBs (rs =-0.74,P＜0.01),while the decreased level of IL-12 was negatively associated with the level of anti-HBs (rs=-0.42,P＜0.01).The level of IL-6 was negatively correlated with the level of IL-12 in the neonatal period and the infantile period (rs=-0.68,-0.70,P＜0.01).Conclusions IL-6 might promote the immune response to hepatitis B vaccination in infants whose mothers were HBsAg-positive,while IL-12 might inhibit the immune response.IL-6 and IL-12 would affect the immune response to hepatitis B vaccination in infants of HBsAg-positive mothers at the same time.
ABSTRACT
Objective To investigate the influencing factors for non/low-response to hepatitis B vaccine in infants of HBsAg-positive mothers.Methods A total of 286 HBsAg-positive pregnant women and their infants were recruited from the Third People's Hospital of Taiyuan during July 2011 to January 2013.The infants were immunized with hepatitis B vaccine according to the 0-1-6 month vaccination schedule and followed up for 12 months.The serum HBV DNA level of mothers,neonates and infants were detected by electro chemilum inescence immunoassay kits and fluorescene quantiative polymerase chain rection.Results Among 286 infants,the rate of non/low-response to hepatitis B vaccine was 18.53％ (53/286).Non-conditional logistic regression analysis indicated that the mother's HBV DNA level ≥ 1 × 107 copies/ml (0R=2.592,95％CI:1.121-5.996) and natural birth (OR=1.932,95％CI:1.021-3.654) were the risk factors for non/low-response to hepatitis B vaccine,the risks were 2.592 times and 1.932 times higher compared with the infants whose mothers were HBV DNA negative and the infants whose mothers had cesarean delivery.There was no multiplicative or additive interaction between high HBV DNA load and natural birth (OR=1.055,95％CI:0.209-5.321),(RERI=1.617,95％CI:-4.038-7.272;AP=0.364,95％CI:-).527-1.225;SI=1.195,95％CI:0.270-13.135).After stratified analysis of mother's HBV DNA level,delivery mode of mothers was not associated with non/low-response of their infants.Conclusion The mother's load of HBV DNA ≥ 1 × 107 copies/ml might be the factor for non/low-response to hepatitis B vaccine in infants of HBsAg positive mothers.

Objective To explore the effect of kangfuxin liquid topical treatment on open wound of postoperative perianal abscess.Methods200 cases of patients with open wound abscess surgery in our hospital from February 2014 to September 2016 were randomly divided into control group and experimental group,with 100 cases in each group.The control group was given conventional treatment, the experimental group were treated by kangfuxin liquid.The relevant therapeutic indicators and clinical healing time between two groups were compared.ResultsThe effective rate of the treatment group was 93.0%, which was significantly higher than that of the control group (85.0%), the difference was statistically significant(P<0.05).The granulation growth period of the experimental group was (5.14±1.41) days, and the average healing time was (15.21±2.49) days.Which were significantly shorter than those of the control group[(7.45±1.32) days, (21.16±2.69) days], and the differences were Statistical differences (P<0.05).ConclusionTo improve the treatment effect to a great extent open wound infection of kangfuxin liquid in treatment of perianal abscess after surgery, shorten the healing time, improve the patient's symptoms, with further clinical promotion and application significance.
ABSTRACT
Objective To investigate the effects of thymoquinone (TQ) on the levels of proteins involved in oxidative stress and cytokine in the brain of rats with type 2 diabetes mellitus.Methods Wistar rats (n=48) were randomly divided into 3 groups:normal control group,model group and TQ treatment group (n =16).The normal control group was fed with clean grade ordinary feed.The model group and TQ treatment group rats were fed with high-glucose and high-fat diet.After 6 weeks' feeding,model group and TQ treatment group rats were administered streptozocin (STZ) (35 mg/kg) to establish type 2 diabetic model by intraperitoneal injection.Then,the model group and TQ treatment group rats were fed with high-glucose and high-fat diet for another 6 weeks.After that,TQ treatment group rats were administered TQ (5 mg/kg) by intraperitoneal injection every other day.The model group rats were injected with an equal dose of ethanol.Six weeks later,all the rats were sacrificed to obtain the hippocampal tissue for the protein extract.The protein levels of nuclear factor erythroid 2-related factor 2 (Nrf2),heme oxygenase-1 (HO-1) and cyclo-oxygenase 2 (COX-2) in the hippocampal tissue were measured by Western blot.Superoxide dismutase (SOD) activity was determined by SOD kit.Blood-glucose meter was used to assess the blood glucose before the rats were sacrificed and after the model was successfully established.All the measurement data was described by the x ± s,measurement data were compared among groups using One Way ANOVA.Results The results by Western blots showed that the levels of the Nrf2 and HO-1 protein were significantly decreased in the model group compared with the normal control group,the levels of the Nrf2 and HO-1 proteins were increased in the TQ treatment group in comparison with the model group (P＜ 0.05).Meanwhile,compared with the normal control group,the SOD activity of the hippocampus in model group was significantly lower (P＜ 0.05);by contrast with the model group,the SOD activity in the TQ treatment group was considerably increased (P＜0.05).By contrast,the COX-2 level in the model group was substantially higher than that in the normal control (P＜0.05),and the COX-2 level in the TQ treatment group was lower than that in the model group (P＜0.05).Conclusions TQ might inhibit inflammation and improve oxidative stress of the brain tissue in the rats with type 2 diabetes mellitus.

Objective To analyze the clinical effect of anti-angina pectoris combined with anxiolytic-depressive drugs in patients with angina pectoris and anxiety and depression and its influence on psychological fluctuation .Methods 100 patients with coronary heart disease and angina pectoris who were treated with anxiety and depression were randomly divided into the observation group and the control group according to the digital table method.The control group were treated with conventional angina pectoris, and the control group were treated with anti-anxiety and depression medication.The left ventricular end-systolic volume ( LVESV ) , left ventricular ejection fraction ( LVEF ) , left ventricular end-diastolic volume (LVEDV), left ventricular end-diastolic volume (LVEDV) and left ventricular end-diastolic volume (LVEDV) and anxiety and depression scores were compared between the two groups before and after treatment.Results The total effective rate of the treatment group was significantly higher than that of the control group (P<0.05).There was no serious adverse reaction in the two groups.The treatment compliance rate in the observation group was significantly better than that in the control group (P<0.05), and the level of cardiac function after treatment in the observation group was significantly better than the control group (P<0.05); observation group before and after treatment anxiety and depression scores were statistically significant (P<0.05), while the control group before and after treatment anxiety and depression score was not statistically significant.Results The combination of anti-angina pectoris and anxiety-depression drugs had better clinical curative effect on patients with angina pectoris and anxiety and depressive patients, and could effectively control the onset of angina pectoris.Meanwhile, they had higher safety and could improve the compliance of patients with clinical treatment.Anxiety and depression, so as to improve the quality of life of patients.
ABSTRACT
Objective To evaluate the efficacy and safety of gefitinib plus capecitabine in treatment of recurrent and metastatic triple negative breast cancer.Methods From Jan.2011 to Jun.,41 patients who have recurrent and metastatic triple negative breast cancer after treated by adjuvant chemotherapy were enrolled in this study They were divided into two groups according to their wishes.The 24 cases in the experimental group were treated with gefitinib plus capecitabine.The 17 cases in the control group were treated with capecitabine.The two groups were followed up for 12 months.They were treated until the disease progression or the toxicity could not be tolerated.Results The objective response rate (ORR) in the experimental group and the control group was 70.83％(17/24) vs 35.29％(6/17).The disease control rate (DCR) in the two groups was 91.67％ (22/24) vs 64.71％ (11/17).The difference between the two groups was statistically significant (P＜0.05).The incidence rate of adverse drug reactions in the two groups was similar (P＞0.05),and the reactions were tolerable.Conclusion Gefitinib plus capecitabine is an effective and safe treatment for recurrent and metastatic triple negative breast cancer with tolerable adverse reactions,and some patients were able to survive for more than 12 months.
ABSTRACT
Through introducing the reason of constructing the evaluation system of medical ethics,this paper summarized the specific ways of the whole-staff participation,content integration,the procedure standardization,the index digitalization,the assessment normalization,the result openness,the application rigidization and the management informatization in the evaluation of medical ethics.Then it concluded the importance and the positive effects of the evaluation system of man-oriented medical ethics in the hospital management and the construction of medical ethics:grasping the sensitive issues and defining the boundary of behaviors;grasping the core problems and standardizing the medical behaviors;grasping the development problems and improving the academic level,and grasping the ideological problems and constructing the humanistic spirit.
