ABSTRACT

Objective:To investigate predictive value of model based on pre-surgical 18F-FDG PET/CT metabolic parameters for mediastinal lymph node metastasis (LNM) in lung adenocarcinoma. Methods:A total of 288 patients with lung adenocarcinoma (135 males, 153 females, age (61.6±8.5) years) who diagnosed and treated in the Fourth Hospital of Hebei Medical University from January 2016 to February 2021 were enrolled retrospectively. All patients underwent 18F-FDG PET/CT examination within 1 month before operation, and underwent complete resection of primary lung tumor and standard lymph node dissection. PET/CT parameters were extracted (PET metabolic parameters: minimum SUV(SUV min), SUV max, SUV mean, SUV standard deviation (SUV std), metabolic tumor volume (MTV) and total lesion glycolysis (TLG); CT parameters: minimum CT value (HU min), maximum CT value (HU max), mean CT value (HU mean), CT value standard deviation (HU std)). Multivariate logistic regression analysis was used for screening parameters and establishing model to predict LNM. ROC curves analyses were used to evaluate the predictive performance of models. Results:Among 288 patients, 90 had LNM, and 361 metastatic lymph nodes (N1: 186, N2: 175) were reported by pathology. SUV min (odds ratio ( OR)=1.859, 95% CI: 1.074-3.220, P=0.027), SUV max ( OR=2.255, 95% CI: 1.306-3.893, P=0.004), SUV mean ( OR=0.277, 95% CI: 0.115-0.665, P=0.004) were predictors of LNM. The AUC of PET/CT model was 0.849 (95% CI: 0.804-0.893), and the sensitivity, specificity, accuracy, and positive and negative predictive values were 87.8%(79/90), 72.2%(143/198), 77.1%(222/288), 59.0%(79/134) and 92.9%(143/154), respectively. Conclusion:The model based on 18F-FDG PET/CT metabolic parameters can improve the accuracy of pre-surgical N-staging in patients with lung adenocarcinoma.

ABSTRACT

Objective:To observe the long-term efficacy and safety of macular buckling (MB) in the treatment of high myopia traction maculopathy.Methods:A retrospective clinical study. From January 2014 to December 2017, 57 eyes of 57 patients with high myopia traction maculopathy who underwent MB treatment at Zhongshan Ophthalmic Center of Sun Yat-sen University were included in the study. Among them, there were 15 males with 15 eyes, average age was 51.80±10.72 years; there were 42 females with 42 eyes, average age was 59.14±11.51 years. There were 21 eyes of 21 cases with highly myopic macular hole with macular detachment (MHMD), and 36 eyes in 36 cases with highly myopic foveoschisis with macular detachment (FSMD), and they were grouped accordingly. All patients underwent best corrected visual acuity (BCVA), optical coherence tomography (OCT), and axial length (AL) measurements. The standard logarithmic visual acuity chart was used for BCVA examination, which was converted into logarithm of the minimum angle of resolution (logMAR) visual acuity during statistics. All patients underwent MB, either on its own or combined with vitrectomy. Patients with significant vitreous macular traction on OCT were treated with combined surgery. One, 3, 6 months and 1, 2, 3, and 4 years after the operation, the same equipment and methods before the operation were used to conduct related examinations, and the long-term efficacy and safety of the two groups of eyes were observed.Results:Before surgery, the logMAR BCVA of eyes in MHMD group and FSMD group were 1.35±0.47 and 1.17±0.59, respectively; 4 years after surgery, they were 1.02±0.49 and 0.73±0.55, respectively. The BCVA improved significantly at postoperative 4 years than preoperative in both groups ( P=0.039, 0.001). In the eyes with MHMD, the BCVA was found to be significant improved 3 years after surgery ( P=0.042). Whereas, in the eyes with FSMD, the BCVA was found to be significantly improved 3 months after surgery ( P=0.013). Macular reattachment was achieved in 100% of cases, while macular hole closure rate was achieved in 66.7% in the MHMD group. In the FSMD group, either macular reattachment rate or the foveoschisis resolution rate was 97.2%. After surgery, choroidal neovascularization was observed in 2 eyes, and 3 eyes with intraretinal cyst. Conclusion:MB may represent a safe and effective surgical option for the treatment of high myopia maculopathy.

ABSTRACT

Objective:To investigate the use of discriminant analysis to predict the risk of nosocomial mortality in patients with traumatic hemorrhagic shock.Methods:The clinical data of 238 patients with traumatic hemorrhagic shock admitted to Peking University People's Hospital from Sep 2013 to Aug 2020 were retrospectively analyzed. Patients were divided into survival group (214 cases) and death group (24 cases). Stepwise discriminant analysis was used to establish a discriminant model.Results:The difference of history of stroke (9.8% vs. 25.0%), main site of bleeding (extremities)(58.9% vs. 29.2%), APACHEⅡ score (16.4±5.1 vs. 23.2±6.1), blood lactic acid [2.1(1.1-3.5) mmol/L vs. 4.9(2.0-13.4) mmol/L] and surgery (92.5% vs. 58.3%) between the two groups was all statistically significant (all P<0.05). Finally, There are five indicators that entered the discriminant model: history of stroke, main site of bleeding (extremities), blood lactic acid, APACHE Ⅱ score and surgery. The area under the ROC curve for predicting the risk of mortality in patients with traumatic hemorrhagic shock was 0.857, 95% CI 0.754-0.959. Conclusions:The established discriminant model has a high accuracy in predicting the risk of in-hospital mortality in patients with traumatic hemorrhagic shock.

ABSTRACT

Objective:To evaluate the difference of dosimetry between three-dimensional and two-dimensional plans based on CT images of occult perforation in brachytherapy of cervical cancer, aiming to provide clinical reference.Methods:A total of 817 patients with cervical cancer received simple intrauterine (intrauterine tandem plus vaginal colpostats) three-dimensional brachytherapy in Chongqing University Cancer Hospital from January 2019 to December 2020 were retrospectively reviewed. Among them, 16 patients had occul uterine perforation. Based on Oncentra Brachy Therapy plan system, the single prescription dose was 6Gy. Three-dimensional (3D group) and two-dimensional (2D group) plans were designed on the perforated CT images The target volume, conformal index (CI), conformal index coformity index (COIN) and organs-at-risk (OAR) D 2cm 3 parameters were used to assess the plans between two groups. Results:The incidence of pccult uterine perforation was 1.96%(16/817) during brachytherapy for cervical cancer. The volume of prescription dose curve in the 3D group was (40.74±14.98) cm 3, significantly smaller compared with (91.46±19.71) cm 3 in the 2D group ( P<0.05), whereas the volume of the high-risk clinical target area wrapped by prescription dose curve did not significantly differ between two groups ( P>0.05). The CI and COIN in the 3D group were 0.79±0.10 and 0.72±0.96, significantly higher compared with 0.38±0.09 and 0.37±0.18 in the 2D group (both P<0.05). The D 2cm 3 of bladder, rectum, sigmoid colon, small intestine in the 3D group were (306.06±77.57) cGy, (252.27±72.60) cGy, (127.25±62.84) cGy and (228.79±94.90) cGy, significantly lower than (548.03±164.21) cGy, (411.16±118.74) cGy, (227.45±94.48) cGy and (450.95±157.96) cGy in the 2D group (all P<0.05). Conclusions:Application of image guidance in brachytherapy of cervical cancer is helpful to detect occult uterine perforation. When occult uterine perforation occurs, the use of three-dimensional plan can basically meet the clinical needs, which is significantly better than the two-dimensional plan.

ABSTRACT

Objective To construct a human renal epithelial cell line HEK293T by CRISPR-Cas9-based site-directed knock-in of vascular endothelial growth factor 165 (VEGF165) gene, and avoid the off-target effect caused by lentivirus infection. Methods The VEGF165 expression vector with homologous arm (pUCm-T-VEGF165 plasmid) and the sgRNA expression vector [pSpCas9(BB)-2A-Puro-sgRNA plasmid] were designed and constructed based on the DNA sequence of the EZH2 gene, and then co-transfected into HEK293T cells. The expression of VEGF165 mRNA was detected by qPCR and the expressions of VEGF165 proteins were detected by Western Blot. Results The qPCR and Western Blot results showed that, comparing with the control, the pUCm-T-VEGF165 plasmid and pSpCas9(BB)-2A-Puro-sgRNA plasmid, the expression of the co-transfection plasmid were significantly increased, i.e. 3.42±0.30 vs. 1.02±0.21, 1.13±0.16 and 0.98±0.18 for the VEGF165 mRNA level (all P<0.01), and 1.13±0.16 vs. 1.02±0.06, 0.88±0.03 and 0.80±0.05 for the VEGF165 protein level (all P<0.01), respectively. Besides, the expression of EZH2 was significantly down-regulated, i.e. 0.14±0.06 vs. 1.08±0.11, 1.02±0.12 and 1.13±0.16 for the EZH2 mRNA level (all P<0.01), and 0.23±0.03 vs. 1.05±0.13, 0.91±0.04 and 0.81±0.06 for the EZH2 protein level (all P<0.01), respectively. This result showed that the VEGF165 was successfully inserted into the EZH2 genome, interfering the EZH2 expression. Conclusions VEGF165 gene can be successfully knocked into HEK293T cells by CRISPR/Cas9 system.

ABSTRACT

Objective To investigate hydrogen peroxide (H2O2) and transforming growth factor-β2 (TGF-β2) induced fibronectin (FN), collagen 1 (COL1), nuclear factor (NF)-κB P65 proteins and interlukin (IL)-1βgene expression in human trabecular meshwork cells (HTMCs), and the interventional mechanism of resveratrol (RSV). Methods (1) HTMCs with 70 to 80%confluency were divided into 5 groups. The experimental groups were treated with serum-free medium and with H2O2 at concentrations of 150, 300, 450 and 800μmol/L. The control group was treated with 0μmol/L H2O2. The protein levels of FN, COL1, NF-κB P65 and NF-κB P65 phosphorylation (P-NF-κB P65) were measured by Western blot assay. The expression of IL-1βgene was measured by qPCR. (2) HTMCs were divided into 3 groups. The control group was treated withserum-free medium and without H2O2 and RSV. The H2O2 group was treated with 300μmol/L H2O2. The H2O2+RSV group was treated with 300μmol/L H2O2 and 25μmol/L resveratrol (RSV). The expressions of proteins and genes mentioned above were detected in three groups. NF-κB P65 nuclear translocation was assessed by immunofluorescence technique. (3) HTMCs were divided into 3 groups. The control group was treated with serum-free medium and without TGF-β2 and RSV. The TGF-β2 group was treated with 5μg/L TGF-β2. The TGF-β2+RSV group was treated with 5μg/L TGF-β2 and 25μmol/L RSV. The expressions of proteins and genes mentioned above were detected in three groups. Results (1) Compared with control group, the protein levels of FN and P-NF-κB P65 were significantly increased in 150, 300, 450 and 800μmol/L groups,the expression levels of COL1 protein and IL-1β gene were significantly increased in 300, 450 and 800 μmol/L groups (P <0.05). There were no statistical significances between other indicators. (2) The expression levels of FN, COL1, P-NF-κB P65 proteins and IL-1βgene were significantly higher in H2O2 group than those in control group, and which were significantly lower in H2O2+RSV group than those in H2O2 group. Compared with control group, only the expression of IL-1βgene was decreased in H2O2+RSV group (P < 0.05). NF-κB P65 was only expressed in cytoplasm in control group, while it was expressed in both cytoplasm and nucleus in H2O2 group. Compared with H2O2 group, NF-κB P65 was mainly expressed in cytoplasm. (3) Compared with control group, the expressions of FN, COL1, P-NF-κB P65 proteins and IL-1β gene were significantly increased in TGF-β2 group (P < 0.05). Compared with TGF-β2 group, the indicators mentioned above were significantly decreased in TGF-β2+RSV group (P<0.05). Conclusion H2O2 and TGF-β2 can upregulate the expression of FN, COL1, P-NF-κB P65 proteins and IL-1βgene in HTMCs, which may be involved in the development and progression of glaucoma. RSV can inhibit the influence of H2O2 and TGF-β2 in HTMCs and exert a protective effect on glaucoma.

ABSTRACT

Objective To knock out Asxl2 gene in murine embryonic fibroblast cell line NIH3T3 using CRISPR/Cas9n system. Methods A pair of sgRNAs which targeted exon 5 of Asxl2 gene were designed and subcloned into the pX462 vec?tor. The recombined plasmids were verified by sequencing and transfected into NIH3T3 cell line. Single cells were isolated through serial dilutions, followed by an expansion period to obtain new monoclonal cell lines. The genomic DNA of the new monoclonal cell lines was extracted and a DNA fragment flanked the target site was amplified by genotyping PCR then se?quenced. Lastly, western blotting were applied to confirm whether Asxl2 was successfully knocked out. Results The CRIS?PR/Cas9n plasmids that targeted Asxl2 were successfully constructed. NIH3T3 cells were co-transfected with the two recom?binant constructs. After puromycin selection, subclonal cell lines were obtained and one of them was validated by genotyping PCR-sequencing. Western blotting also confirmed that Asxl2 was completely depleted in the NIH3T3 cell line. Conclu?sion CRISPR/Cas9n plasmids that targeted Asxl2 were successfully constructed therefore a Asxl2 knockout NIH3T3 stable cell line was established via this system.

ABSTRACT

Objective To investigate the clinical and pathological features,diagnosis,differential diagnosis,treatment and prognosis of secondary Hodgkin's lymphoma of ureter.Methods We retrospectively analyzed one case with retroperitoneal Hodgkin's lymphoma involving right ureter.A 63-year-old male patient was referred to our hospital on January 22th,2013 with right hydronephrosis for 15 days,detected by abdominal color Doppler ultrasound due to constipation and difficult defecation without any urinary symptoms.Urinary CT scan revealed that there were dilation and hydrops of right pelvic and ureter in the middle and upper segment.The distal portion of ureteral wall was thick with a stenosis lumen.There was multiple larged lymph nodes surrounding the abdominal aorta.So,it was clinically diagnosed as right ureteral carcinoma with lymphadenopathy and right hydronephrosis.The patient was then performed ureteroscopic inspection under general anesthesia.There was too narrow to go through smoothly the proximal ureter when the ureteroscope ascended 15 cm.Then,the exploratory surgery of right ureter was subsequently undergone.During operation,periureteral nodular mass and thickened wall were seen in the distal segment of ureter.Then the ureter lesion was partially excised with 1 cm and fast frozen pathology was undergone during operation.The result suggested chronic inflammation of ureteral.A 6Fr double J stent was left in the ureter.Then,the ureter was closed by 3-0 monocryl suture.Results The final pathological diagnosis was retroperitoneal Hodgkin's lymphoma with the lymph node involving the right ureter.After 40 days,the patient manifested high fever,night sweat,general lymphoadenomegalies.So,the clinical stage was classified as stage Ⅱ EB and poor prognosis group.Then,the patient received regular chemotherapy according to the ABVD (pirarubicin 20 mg/m2,bleomycin 10 mg/m2,vinblastine 1.4 mg/m2,dacarbazine 375 mg/m2) regimen over 8 cycles.Finally the symptomatology and diagnostic reassessment (hemato-chemical examinations and PET/CT) showed a clinical complete recovery after the follow-up period of 3 months.The follow-up plan is ongoing.Conclusions Because secondary Hodgkin's lymphoma of ureter is rare with concealed onset feature,lacking of characteristic clinical manifestations,it is relatively difficult to achieve the diagnosis and differential diagnosis.Therefore,pathology and immunohistochemistry should be assigned to confirm the diagnosis.It is stressed that physicians should be aware of the possibility of malignant lymphoma when unexplained hydronephrosis and thickness of the ureteral wall are found clinically.Generally it has a good prognosis and combination therapy for the treatment is given priority to with chemotherapy.

OBJECTIVE@#The study aimed to investigate the efficacy and adverse effects of sublingual immunotherapy (SLIT) of dust mite drops to allergic rhinitis with mite allergy. The compliance and satisfaction of SLIT were also assessed.@*METHOD@#One hundred and three patients of allergic rhinitis sensitive to dust mites were treated with SLIT for 6 months or more. The symptom questionnaire,including items on rhinorrhea, sneezing, nasal obstruction, itchy nose, olfactory disturbance, eye discomfort and sleep disturbance were obtained before and 6 months after SLIT. The patients' satisfaction and adverse effects were also investigated.@*RESULT@#Seventy-five of the 103 patients insist on SLIT for more than 6 months and completed the questionnaire. The duration of receiving SLIT was 9.8 months on average (range from 6 to 13 months). The satisfaction rate was 89.3%. The drop-out rate of SLIT was 31.0%.@*CONCLUSION@#The subjective symptoms were improved with SLIT in patients with allergic rhinitis sensitive to dust mites. The drop out rate was high despite of the symptomatic improvement.

ABSTRACT

Objective To investigate the effect of bortezomib with arsenic trioxide different concentration on the cell cycle and apoptosis of Raji cells. Methods Flow cytometry analysis showed that the relative number of cells in different phases and the percentages of cells calculated in G1 and S phase of the cell cycle and apoptosis were assessed after treatment with As2O3 and BOR or in combination with BOR in different concentration at indicated time (24 h, 48 h, 72 h). Results Flow cytometric analysis showed that the cell cycle was arrested at G1 phase, the number of cells G1 period increased significantly, and S phase decreased on Raji cells after As2O3 treatment. The relationship between the cellular DNA contents and the concentration of As2O3 showed a dose-and time-dependent manner (P <0.0001). But it was found that BOR had no effect on Raji cell cycle, but, in two drugs combination, cell apoptosis rate significantly increased from 16.98 % to 45.84 %. Conclusion The results show that As2O3 exerted variable and definite effects on lymphoma Raji cells, which indicated that As2O3 might induce apoptosis and arrest cell cycle. The combination of two drugs had a effective and synergistic effect on apoptosis.

ABSTRACT

Objective To evaluate the therapeutic effect of 32P application and interventional therapy in skin hemangioma, and to sum up the role of nursing in the process of the treatment. Methods 734 cases of skin hemangiorna were involved in the study. Personalized treatment strategy and nursing measures were implemented according to different kinds of skin hernangioma, 32p application device was made with the dose of 1 Gy per square centimeter every day, and the total dose of interventional therapy was from 6.8μCi to 10.0μCi per square centimeter according to the site of lesions and the patients' age. The treatment interva] was about one and a haft month or two months. The specific nursing measures were as follows: effective communication should be undertaken to remove the concerns of patients before therapy. Meanwhile, the lesions should be taken a picture by a digital camera before and after therapy. Thus, the effect could be evaluated objectively. In addition, the follow-up by telephone also was done in the study. Results the cure rate and the effective rate of 32P in the treatment of skin hemangioma were 78.88% and 94.14% respectively.The treatment effect was the best in hemangioma simplex among different kinds of skin hemangioma. The treatment effect had a negative correlation with the age of the patients. Selective nursing reduced incidence of complication. Conclusions There's a satisfactory effect of 32p application and interventional therapy in the treatment of skin hemangioma. Meanwhile, nursing plays an important role in the treatment.
