ABSTRACT

Objective:To explore the expression and clinical significance of KIF20A in HER2-positive breast cancer.Methods:The clinicopathological characteristics of 82 cases of HER2-positive breast cancer were retrospectively analyzed. The expression of KIF20A in tissues was detected by immunohistochemical method, and the expression of KIF20A in HER2 overexpression breast cancer and its relationship with clinicopathological characteristics were analyzed. The mRNA level of KIF20A in HER2-positive breast cancer tissues and normal tissues adjacent to cancer were analyzed by bioinformatics methods.Results:The positive expression of KIF20A was in the nucleus, forming brown-yellow particles. In HER2-positive breast cancer tissues, the positive high expression rate of KIF20A is 57.3%, while it is mainly low or no expression in the adjacent tissues. The high expression of KIF20A is significantly correlated with tumor size and pTNM stage, while the correlation with age and tumor grade is not statistically significant. The results of bioinformatics analysis suggest that the high expression of KIF20A in invasive breast cancer is significantly related to poor disease-free survival.Conclusions:KIF20A is abnormally expressed in HER2-positive breast cancer, which is related to the tumor grade and pTNM stage of HER2 overexpression breast cancer, and the high expression of KIF20A indicates a poor prognosis.

ABSTRACT

ObjectiveTo investigate the efficacy and safety of sequential lenvatinib therapy after stereotactic body radiotherapy (SBRT) in the treatment of advanced primary liver cancer. MethodsA total of 18 patients with advanced primary liver cancer who were admitted to The Fifth Medical Center of Chinese PLA General Hospital from October 2018 to May 2019 were enrolled, among whom there were 4 patients with BCLC stage B liver cancer and 14 patients with BCLC stage C liver cancer. The prescribed dose of planning target volume was 48-55 Gy (median 50 Gy) in 6-9 fractions, and the median of single dose was 6 (5-9) Gy per fraction. Oral administration of lenvatinib was given since 1 week after SBRT was finished, with a median medication time of 9.5 (3.6-25.8) months. Follow-up was performed once a month for the first 3 months after treatment and once every 3 months after 3 months of treatment. The Kaplan-Meier method was used to calculate overall survival (OS) rate, progression-free survival (PFS) rate, and local control (LC) rate, and the incidence rates of adverse reactions and complications were also observed. ResultsUp to the follow-up on November 30, 2020, a total of 8 patients died, among whom 3 died of liver failure, 3 died due to tumor progression, 1 died of perforation of gallbladder, and 1 died of gastrointestinal bleeding. At 3, 6, 9, 12, and 18 months of treatment, the OS rates were 100%, 94%, 83%, 72%, and 67%, respectively, the PFS rates were 100%, 67%, 50%, 22%, and 17%, respectively, and the LC rates were 100%, 94%, 94%, 94%, and 94%, respectively; the median OS time was >18 months, and the median PFS time was 9 months. Of all patients, 1 (6%) had a grade 3 adverse reaction during SBRT and 2 (11%) experienced a grade 3 adverse reaction during lenvatinib treatment, and no fatal adverse reaction was observed. ConclusionIt is preliminarily proved that sequential lenvatinib therapy after SBRT is an effective and safe treatment method for advanced primary liver cancer.

ABSTRACT

This article reported a case of nemaline myopathy caused by KLHL40 gene complex heterozygous mutations. This baby girl presented with shortness of breath, low myodynamia, and low muscle tension immediately after birth. However, her symptoms became worse after conventional treatment. Physical examination found lower muscle strength and muscle tone in four limbs and no primitive reflexes. The biochemistry test showed increased serum creatine kinase (CK). A muscle biopsy was not performed. The second-generation gene test confirmed the KLHL40 gene complex heterozygous mutations, which was a known mutation c.932G>T (p.R311L) and a de novo mutation c.1487T>A (p.M496K), inherited from the father and mother, respectively. Nemaline myopathy is a rare congenital muscular disease characterized by nemaline bodies in muscle fibers. Pathological and genetic diagnoses are the gold standards for the diagnosis of this disease.

ABSTRACT

Objective To evaluate the efficacy and safety of single bolus high dose (SD group) ATG-Fresenius induction therapy in kidney transplantation vs.multiple low dose (MD group) administration.Methods A multiple center,prospective,randomized and controlled clinical study was performed on 280 de novo renal transplant recipients from 19 centers.Patients were randomized into 2 groups as follows:SD group,a single high dose (7-9 mg/kg) of ATG-F infused as an induction agent before the vessel anastomoses;MD group,2 mg/kg of ATG-F daily administrated in postoperative 4 days.All the patients accepted maintenance immunosuppressive protocol including tacrolimus,mycophenolate and prednisone.Patients were assessed and data were collected at regular schedule clinic visits on the day 1,3,7,14,30,90,180,270 and 365.The primary end point of efficacy was therapeutic failure rate [the number of death,grafts loss and acute rejection (AR)].The event first occurred should be used in the classification of patients.The non-inferiority evaluation of the two treatment regimens was done based on treatment failure rate.The secondary end points of efficacy were the incidence of AR,delayed graft function (DGF),1-year survival rate of patients and grafts,and serum creatinine at each visiting point.The indicators for safety evaluation included hemotologic variation and incidence of adverse events.Results The therapeutic failure rate in SD group was non-inferior to the MD group (17.24% vs.23.08%).AR was the major cause of therapeutic failure and there was similar incidence of AR between SD gronp and MD group (12.07% vs.21.37%).There was no significant difference in the incidence of DGF between SD group and MD group (12.07% vs.6.84%,P =0.1721).The 1-year patient's survival rate and 1-year graft survival rate in SD group and MD group showed no significant difference (96.55% vs.98.29%,P =0.6714;94.83% vs 98.29%,P =0.2750).The serum creatinine level showed no significant differences between two groups at each visit point.There was also no significant difference in total incidence of adverse events between the two groups.In addition,there was also no statistically significant difference in the incidence of concerned and drug-related adverse events between the two groups,including infection,hemotologic abnormality,liver or renal dysfunction,gastrointestinal disorder,etc.After ATG--F administration,peripheral blood lymphocytes in the SD and the MD group immediately decreased but nearly restored to the normal level on the postoperative day 30 and 90 respectively.No severe granulocytopenia,erythropenia or thrombocytopenia occurred in both two groups.Conclusion The efficacy and safety of single high dose of ATG-F induction are non-inferior to multiple low dose ATG-F induction,moreover,single high dose of ATG-F induction is administered more conveniently and economically.

ABSTRACT

Objective To evaluate the role of autophagy in the spinal cord in the maintenance of postherpetic neuralgia (PHN) in mice.Methods Forty-eight SPF Kunming mice,aged 6-8 weeks,weighing 18-22 g,were divided into 4 groups (n=12 each) using a random number table:normal control group (group C),group PHN,PHN plus autophagy inducer rapamycin group (group PHN+R) and PHN plus autophagy inhibitor 3-methyladenine (3-MA) group (group PHN+3-MA).PHN model was established by intraperitoneal injection of resiniferotoxin 0.2 μg/g.In PHN+R and PHN+3-MA groups,rapamycin 1 μg/g and 3-MA 2 μg/g were intraperitoneally injected once a day for 14 consecutive days starting from 7 days after resiniferotoxin injection.The equal volume of normal saline was given instead in group PHN.The mechanical paw withdrawal threshold (MWT) and thermal paw withdrawal latency (TWL) were measured on 1st,3rd,6th,9th,12th and 14th days of administration of autophagy regulator (before administration).The animals were sacrificed after the last measurement of pain threshold,and the spinal cord was removed for examination of the ultrastructure and for determination of the expression of microtubule-associated protein light chain 3 Ⅱ (LC3 Ⅱ),LC3 Ⅰ,Beclin-1 and P62 by Western blot.The ratio of LC3 Ⅱ to LC3 Ⅰ expression (LC3 Ⅱ /Ⅰ) was calculated.Results Compared with group C,the MWT was significantly decreased,TWL was prolonged,LC3 Ⅱ/Ⅰ was increased,Beelin-1 expression was up-regulated,P62 expression was down-regulated (P<0.05),and the number of autophagosomes was increased under electron microscope in group PHN.Compared with group PHN,the MWT was significantly decreased,TWL,was prolonged,LC3 Ⅱ/Ⅰ was increased,Beclin-1 expression was up-regulated,P62 expression was down-regulated (P<0.05),and the number of autophagosomes was increased under electron microscope in group PHN+R,and the MWT was significantly increased,TWL was shortened,LC3 Ⅱ/Ⅰ was decreased,Beclin-1 expression was down-regulated,P62 expression was up-regulated (P<0.05),and the number of autophagosomes was decreased under electron microscope in group PHN+3-MA.Conclusion The maintenance mechanism of PHN may be related to the excessive activation of autophagy in the spinal cord of mice.

ABSTRACT

Objective To explore the clinical value of the monitoring of electronic cardiac index (CI) in the evaluation of neonatal congenital heart disease complicated with heart failure. Methods Sixty neonates with congenital heart disease treated in neonatal department from March 1, 2016 to December 30, 2016 were selected, and divided into severe group (n=11), moderate group (n=15), mild group (n=34), and no heart failure group (n=10) according to the modified Ross heart failure score. CI was measured by electronic force measurement. Left ventricular ejection fraction (LVEF) and pulmonary arterial pressure (PAP) were measured by echocardiography. Venous blood sampling was collected to detect the N-terminal type B brain natriuretic peptide (NT-proBNP). Results The neonates in the severe group were mainly under 2-week-old, while those in the mild group and the moderate group were more than 2-week-old. The differences of CI, LVEF, NT-proBNP, and PAP among the groups were statistically different. The CI and LVEF values were lowest in the severe group, followed by moderate group and mild group, and the highest in no heart failure group. The NT-proBNP and PAP values were the highest in the severe group, followed by moderate group and mild group, and the lowest in no heart failure group. Correlation analysis showed that CI was positively correlated with LVEF (r=0.845, P<0.001), and negatively correlated with NT-proBNP (r=-0.886, P<0.001); CI and PAP were weakly negatively correlated (r=-0.595, P<0.001). Conclusions CI reflects the degree of heart failure to some extent and has some clinical value.

Correlation analysis showed that CI was positively correlated with LVEF (r=0.845, P<0.001), and negatively correlated with NT-proBNP (r=-0.886, P<0.001); CI and PAP were weakly negatively correlated (r=-0.595, P<0.001). Conclusions CI reflects the degree of heart failure to some extent and has some clinical value.
