ABSTRACT

OBJECTIVE@#To dynamically observe the levels and activities of von Willebrand factor (vWF) and ADAMTS-13 (a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13) in plasma of children with congenital ventricular septal defect (VSD) during perioperative period, and explore the value of plasma vWF antigen (vWF:Ag) and ADAMTS-13 activity (ADAMTS-13: AC) in evaluating vascular endothelial injury and prognosis in children with VSD.@*METHODS@#In this cross-sectional study, a total of 74 children with VSD who underwent surgical treatment in TEDA International Cardiovascular Hospital from September 2018 to March 2019 were enrolled in the observation group. Among them, there were 28 cases of pure VSD, 32 cases of VSD combined with pulmonary hypertension, and 14 cases of VSD combined with valvular heart disease. 31 healthy children who underwent physical examination in Tianjin Children's Hospital during the same period were collected as the control group. The biochemical indexes of the children at admission were recorded. Peripheral plasma was collected at admission, postsurgery day 0 and day 1, respectively, and the levels of vWF activity (vWF:AC), vWF:Ag, ADAMTS-13 antigen (ADAMTS-13:Ag) and ADAMTS-13:AC were detected.@*RESULTS@#The level of plasma vWF:Ag and vWF:AC in the observation group before surgery were significantly lower than those in the control group (P<0.001), and increased continuously, on postsurgery day 0 and day 1 (P<0.001). The level of ADAMTS-13:Ag in the observation group before surgery was significantly higher than that in the control group (P<0.001), which decreased significantly on postsurgery day 0 (P<0.001), and increased significantly on postsurgery day 1 compared with postsurgery day 0 (P=0.033). The level of ADAMTS-13:AC in the observation group before surgery was significantly lower than that in the control group (P=0.015), which decreased significantly on postsurgery day 0 (P=0.037), and increased on postsurgery day 1, but the difference was not statistically significant (P=0.051). The changes of vWF and ADAMTS-13 in the three subgroups were basically similar to the observation group. vWF: Ag/ADAMTS-13: AC ratio on postsurgery day 0 and day 1 had high diagnostic value in vascular endothelial injury (AUC=0.80, P<0.001; AUC=0.93, P<0.001). Preoperative vWF and ADAMTS-13 levels, and related baseline indicators were not correlated with postoperative infection, bleeding, thrombosis,etc.@*CONCLUSION@#Preoperative vWF: Ag, vWF: AC and ADAMTS-13: AC levels in children with VSD are low, while the level of ADAMTS-13: Ag is high. After surgery, the levels of vWF: Ag and vWF: AC are increased and the level of ADAMTS-13: Ag is decreased. The postoperative vWF: Ag/ADAMTS-13: AC ratio shows high diagnostic value in evaluating vascular endothelial injury. There is no correlation between preoperative vWF and ADAMTS-13 levels with perioperative clinical events.

ABSTRACT

OBJECTIVE@#To explore application value and efficacy of personalized osteotomy in primary total knee arthroplasty (TKA) for severe varus knee osteoarthritis.@*METHODS@#From June 2018 to January 2020, 36 patients (49 knees) with severe varus knee osteoarthritis were treated, including 15 males (21 knees) and 21 females (28 knees), aged from 59 to 82 years old with an average of (67.6 ± 6.5) years old;the course of disease ranged from 9.5 to 20.5 years with an average of (15.0 ± 5.0) years;11 patients (15 knees) with Kellgren-Lawrence grade Ⅲ and 25 patients (34 knees) with grade Ⅳ according to Kellgren-Lawrence grading. According to AORI clsssification of tibial bone defects, 8 patients (15 knees) were typeⅠTa and 16 patients (18 knees) were typeⅡ T2a. All patients' femor-tibial angle (FTA) was above 15°, and received primary TKA with personalized osteotomy. Thirty-three patients (45 knees) were treated with posterior-stabilized (PS) prostheses, 13 patients (15 knees) with PS prostheses combined with a metal pad and extension rod on the tibial side, and 3 patients (4 knees) with legacy constrained condylar knee (LCCK) prostheses. FTA, posterior condylar angle (PCA), medial proximal tibial angle (MPTA) and lateral distal femoral angle (LDFA) before and after operation at 1 month were measured and compared by using picture archiving and communication systems (PACS). Recovery of lower limbs before and after operation at 12 months was evaluated by American Knee Society Score(KSS), and complications were observed and recorded.@*RESULTS@#All 36 patients (49 knees) were followed up from 15 to 40 months with an average of (23.46±7.65) months. FTA, MPTA were corrected from preoperative (18.65±4.28)° and (83.75±3.65)° to postoperative (2.35±1.46)° and (88.85±2.25)° at 1 month, respectively (P<0.001). PCA was decreased from (2.42±2.16)° before operation to (1.65±1.35)° at 1 month after operation, LDFA improved from (89.56 ± 3.55)° before operation to (91.63±3.38)° at 1 month after operation (P<0.05). KSS increased from (67.58±24.16) before opertion to(171.31±15.24) at 12 months after operation, 14 patients (19 knees) got excellent result, 19 (26 knees) good, and 3 (4 knees) fair.@*CONCLUSION@#Personalized osteotomy is helpful for recovery of axial alignment of lower limbs and correct placement of prosthesis, could effectively relieve pain of knee joint, recover knee joint function.

ABSTRACT

Aim To discuss the potential key mechanism of mogroside V in relieving pulmonary inflammation in asthmatic mice based on transcriptomics and proteomics. Methods Ovalbumin(OVA)was chosen to induce female BALB/C mouse asthma model, and the mice were treated with mogroside V to observe the pathological changes of lung tissues. Lung tissues in groups of natural control, ovalbumin control and mogroside V control were chosen for transcriptomic and proteomic analysis, and differential genes and proteins were screened for tendency analysis, followed by KEGG enrichment analysis for the potential genes and proteins. Results The results of lung morphological observation and HE revealed that mogroside V attenuated the OVA-induced pulmonary inflammation. Differential genes and proteins were selected from RNA-seq and DIA analysis. In the analysis of omics 454 genes increased in comparison between groups of natural control with ovalbumin control and decreased in comparison between groups of mogroside V control with ovalbumin control in 1 122 potential genes, and 111 genes were of opposite features. A total of 238 proteins increased in comparison between groups of natural control with ovalbumin control and decreased in comparison between groups of mogroside V control with ovalbumin control in 497 potential proteins, and 91 proteins were of opposite features. The PI3K/Akt signaling pathway was enriched from KEGG and tendency analysis of transcriptomics and proteomics. The key factors of Igha, Ighg1, PI3K and Akt increased in ovalbumin control group and decreased in mogroside V control group by the validation of molecualr biology experiments. Conclusions Transcriptomic and proteomic analysis exhibits that mogroside V relieves asthma in mice through inhibiting the activation of key factors including Lgha, Lgh1, PI3K and Akt, depressing the signaling pathway, attenuating pulmonary inflammation to reach the goal of moistening lung and relieve cough, which provides a reference for drug development of asthma.

ABSTRACT

BACKGROUND: Until now, there are no reliable methods for the treatment of urinary incontinence after radical prostatectomy. Some limitations exist in drug therapy, mid-urethral suspension, and filling agent treatment. Therefore, the use of autologous adipose-derived stem cells (ADSCs) is expected to become a first-line treatment strategy for urinary incontinence after radical prostatectomy. OBJECTIVE: To report our initial experience with transurethral injection of autologous ADSCs for the treatment of urinary incontinence after radical prostatectomy. METHODS: Patients and their families were informed of possible risks and benefits prior to the participation in the trial. After providing written informed consent, six patients with persistent urinary incontinence after radical prostatectomy were enrolled in the study. Under general anesthesia, about 50 mL of adipose tissue was obtained from each patient by liposuction. ADSCs were obtained by separation with centrifugation using the Celution cell-processing device. A mixture of ADSCs and adipose tissue was transurethrally injected into the submucosal space of the membranous urethra. Functional and anatomical improvement was assessed through a 24-hour pad test, validated patient questionnaire, urethral pressure profile, and magnetic resonance imaging (MRI) through 12-week follow-up. RESULTS AND CONCLUSION: Urine leakage volume was improved with time in all patients in the 24-hour pad test, with the exemption of temporal deterioration in two patients at the first 2 weeks post-injection. Subjective symptoms and quality of life assessed on the basis of questionnaire results showed similar improvement. The mean maximum urethral closing pressure increased from 4.312 kPa to 6.223 kPa at 12 weeks after cell injection. MRI results showed an increase in functional profile length (from 6.1 to 8.3 mm) between the lower rim of the pubic bone and the bladder neck. Adverse events, such as pelvic pain, inflammation, or de novo urgency, were undetected in any case during the follow-up. To conclude, the transurethral injection of autologous ADSCs can be a safe and effective treatment for urinary incontinence after radical prostatectomy.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the sequence-dependent effect of combined use of gemcitabine and pemetrexed on the proliferation of human pancreatic carcinoma cell lines BXPC-3 and PANC-1 in vitro and explore the cellular mechanism.</p><p><b>METHODS</b>MTT assay was used to determine the proliferation of the two cells after addition of the two drugs in different sequences, and the cell cycle changes were analyzed by flow cytometry.</p><p><b>RESULTS</b>Both gemcitabine (10(-7)-10 mg/ml) and pemetrexed (10(-7)-10 mg/ml) significantly inhibited the proliferation of BXPC-3 and PANC-1 cells in a dose- and time-dependent manner. The effect of combined administration of gemcitabine and pemetrexed on the cell proliferation varied with the order of the drug delivery, and addition of gemcitabine 24 h after pemetrexed administration produced a significant enhancement of the inhibitory effect as compared with simultaneous drug administration (P<0.05) or the administration of the two drugs in a reverse order (P<0.05). Compared with the control group, combined administration of gemcitabine and pemetrexed caused obvious cell cycle arrest at G1 and S phases (P<0.05). Simultaneous administration of the two drugs resulted in significantly reduced G2-phase cells (P<0.05); addition of gemcitabine prior to pemetrexed caused cell cycle arrest in G1 phase (P<0.05), while the reverse caused cell cycle in S phase (P<0.05).</p><p><b>CONCLUSION</b>Both gemcitabine and pemetrexed can inhibit the proliferation of BXPC-3 and PANC-1 cells, and their synergetic effect depends on the sequence of their administration. The sequential administration of pemetrexed followed by gemcitabine produces significant synergetic effects against the cell proliferation, which might not be associated with their influence of the cell cycle.</p>

ABSTRACT

Objective To investigate the sequence-dependent effects of gemcitabine plus erlotinib on the proliferation of human pancreatic carcinoma cells,BXPC-3 and PANC-1,and the possible mechanisms involved.Methods The expressions of mRNA and protein of endothelial growth factor receptor(EGFR)were determined by RT-PCR and Western blotting respectively.MTT assay was used to examine the effects of gemcitabine(3?10-11-3?10-2mol/L)and erlotinib(10-8-10-4mol/L),respectively,on the proliferation of human pancreatic carcinoma cells,then the IC50 was calculated subsequently.The effects of gemcitabine(IC50)and erlotinib(10-5mol/L)either administered alone,simultaneously,or sequentially(with 72h or 24h interval)on the proliferation of cells with MTT assay.Cell cycle was detected by flow cytometry.Results Both mRNA and protein of EGFR were expressed in BXPC-3 and PANC-1 cells.Gemcitabine(3?10-10-3?10-2mol/L)and erlotinib(10-6-10-4mol/L)significantly inhibited the proliferation of BXPC-3 and PANC-1 cells in a time-and concentration-dependent manner.The effects of gemcitabine plus erlotinib on cell proliferation were sequence-dependent.The inhibitory effects on cell proliferation was enhanced when administered simultaneously(P=0.034;P=0.049)or erlotinib was administered 24h prior to gemcitabine(P=0.001;P=0.025)in comparison to that of each drug used alone.However,administration of erlotinib 24h after that of gemcitabine(P=0.499,P=0.824)exerted no additive effects on the cell proliferation when compared with the effect of gemcitabine used alone.No statistical difference existed in the inhibitory effects on cell proliferation between the simultaneous administration of both drugs and the gemcitabine administration following erlotinib(P=0.199,P=0.767).Erlotinib plus/or gemcitabine treatment resulted in the block of cell cycle of BXPC-3 cells at G1 phase.Conclusions Both gemcitabine and erlotinib can inhibit the proliferation of BXPC-3 and PANC-1 cells.The concurrent administration or sequential administration of gemcitabine following erlotinib exerts stronger additive effects on cell proliferation than when gemcitabine is used alone.However,the additive effects are not related to the influence of the both drugs on cell cycles.
