RESUMO
Objective:To investigate the effects of thoracic paravertebral nerve block combined with propofol intravenous anesthesia (PPA) on hemodynamic parameters, inflammatory stress indexes, postoperative analgesia and immune indexes in patients with lung cancer undergoing radical surgery.Methods:116 patients with lung cancer admitted to the Southern Theater General Hospital from January 2020 to December 2021 were randomly divided into observation group and control group, with 58 patients in each group. The observation group received PPA combined with general anesthesia, and the control group received sevoflurane inhalation combined with general anesthesia; the hemodynamic parameters, the amount of anesthetic and analgesic drugs used during and after the operation, the pain score of the patients after the operation, the serum interleukin-6 (IL-6), interleukin-10 (IL-10), cortisol (Cor), norepinephrine (NE), vascular cell growth factor-C (VEGF-C), transforming growth factor-β 1(TGF-β1) and T lymphocytes before and after the operation, adverse reactions of the two groups were monitored and compared.Results:The intraoperative dosage of remifentanil and postoperative dosage of sufentanil in the observation group were lower than those in the control group (all P<0.05). There was no statistically significant difference in cardiac output (CO), systemic vascular resistance index (SVRI) and extravascular lung water index (EVLWI) between the observation group and the control group at T 0 to T 3 (all P>0.05); The mean arterial pressure (MAP) at T 1 to T 2 in the observation group was higher than that in the control group, and the MAP at T 3 was lower than that in the control group (all P<0.05). There was no significant difference between observation group and control group in Visual Analogue Scale (VAS) scores at resting state and coughing state 2 h after surgery(all P>0.05). The VAS scores in the observation group at resting state were lower than those in the control group at 4 h and 12 h after surgery (all P<0.05), and the VAS scores in the observation group at coughing state were lower than those in the control group at 4 h, 12 h and 24 h after surgery (all P<0.05). Before surgery, there was no significant difference in serum levels of IL-6, IL-10, Cor, NE, VEGF-C and TGF-β1 between observation group and control group (all P>0.05). The serum levels of IL-6, NE and VEGF-C in observation group were lower than those in control group 24 h after surgery (all P<0.05). Before surgery, there was no significant difference in CD3 +, CD4 + and CD8 + between observation group and control group (all P>0.05). 24 h after operation, the CD3 + in observation group was higher than that in control group ( P<0.05). The incidence of adverse reactions in observation group (10.34%) was lower than that in control group (24.14%, P<0.05). Conclusions:PPA anesthesia for patients undergoing radical resection of lung cancer is conducive to maintaining the stability of hemodynamic parameters, reducing the inflammatory stress response of patients, the impact of surgery on patients′ immune function, and the amount of anesthetic drugs and postoperative analgesics during surgery.
RESUMO
Theaflavins are a class of natural products extracted from black tea or green tea, with significant anti-tumor effects on gastric cancer, liver cancer, breast cancer and other tumors. Theaflavins were once considered as the new products for anticancer therapy. However, the anti-tumor mechanism of theaflavins involves a variety of biological processes, and the regulation is complex. Therefore, this article summarizes the role of theaflavins in promoting tumor cell apoptosis, inducing tumor cell mitotic arrest and regulating tumor immunity, and reviews the inhibition of tumorigenesis and growth through MAPK, PI3K/AKT, Hedgehog, NF-κB, JAK/STAT and Wnt/β-Catenin signal pathways, in order to provide new ideas for cancer treatment and anti-cancer drug development.
RESUMO
Objective:To explore the clinical characteristics and short-term prognosis of reoperation of congenital muscular torticollis (CMT).Methods:A total of 12 cases of recurrent CMT treated in the First Affiliated Hospital of Zhengzhou University from May 2015 to May 2018 were recruited, involving 9 boys and 3 girls with the mean age of 13.2 (8-16) years.The causes of disease recurrence were analyzed, and the postoperative appearance of the children was observed by follow-up.In addition, the prognosis of CMT was evaluated by patient satisfaction survey and Lee score criteria.Results:Among the 12 patients, 10 cases were treated in other hospitals and 2 cases in this hospital.The age of the first surgery ranged from 6 months to 2.2 years.Surgical methods included minimally invasive small needle knife (2 cases), single head release of small incision (5 cases), simple amputation (7 cases) and broken end silk thread ligation (4 cases). During the second surgery, contracture and adhesion of sternocleidomastoid muscle at varying degrees were confirmed, including contracture and adhesion of platysma muscle (3 cases), difficulty in separation of jugular sheath (8 cases), and repair of rupture of internal jugular vein (2 cases). Bipolar release of sternocleidomastoid muscle was performed in all surgeries, and tension-free alignment of the neck to the midline was the complete basis for release.The postoperative appearance of all children was satisfied.They were followed up for an average of 2.3 (1.2-3.0) years.Nine and 3 cases graded more than 90 and 80 patient satisfaction scores, respectively.Lee scores reflected the range of motion of head and neck, and the distance and degree of head deviation from the midline, which yielded excellent, good and fair in 12 cases, 8 cases and 3 cases, respectively.Conclusions:Incomplete release is believed as the basic cause of recurrence in children with CMT.Meanwhile, muscle scar adhesion, early operative age, minimally invasive incision and lack of postoperative rehabilitation may also be the direct factors for CMT recurrence.For recurrent patients, satisfactory therapeutic effect can be achieved through bipolar release, especially complete release of the lower pole, combined with postoperative neck traction, fixation and rehabilitation exercise.
RESUMO
Objective:To evaluate the effect of laparoscopic-assisted anorectoplasty in the treatment of children′s congenital anal atresia.Methods:In this study , 49 children undergoing laparoscopic-assisted anorectoplasty between Mar 2009 and Mar 2015 were compared in terms of outcomes with 42 children under going posterior sagittal anorectoplasty during this period.The post-operative complications, bowel functions and courses were evaluated.Results:The ratio of primary healing in laparoscopic-assisted anorectoplasty was higher than posterior sagittal anorectoplasty(22 % vs. 10%, χ 2=4.306, P=0.038), the age of sequential operation in the former was lower than control group [(9.9±6.5) d vs. (13.4±5.1) d, t=2.823, P=0.003]. The perioperative complications were lower than that in the control group(20% vs. 50%, χ 2=8.817, P=0.003), the bowel function was better than control group(χ 2=7.419, P=0.025). Conclusions:Perioperative complications in laparoscopic-assisted anorectoplasty is lower than posterior sagittal anorectoplasty, with better bowel function and higher primary healing rate.
RESUMO
0bjective To synthesis evidence of self-efficacy-based interventions to improve self-management and health behaviour change in patients with diabetes. Methods PubMed, Cochrane, MEDLINE, CINAHL, EBSCO and Web of Science were searched from 1977 to August 2018. The primary outcomes were self-efficacy and self-care ability. Pooled effect sizes of standardised mean difference ( SMD ) were calculated if outcome measurements and the units were different, and if outcome measurements and the units were the same, such as measuring blood glucose by HbA1c, weighted mean difference ( WMD ) were used to calculate pooled effect sizes. Results Nine eligible randomised control trials (RCTs) including 1578 participants were identified. The results showed that interventions based on self-efficacy significantly improved patients′self-efficacy ( SMD=0.69, 95% CI :0.58 to 0.80, P<0.05) and self-management ( SMD=0.93,95% CI : 0.74 to 1.12, P<0.05), helped them control blood glucose ( WMD=-0.69, 95% CI :-0.85 to-0.52, P<0.05), reduced hospitalisation and emergency times, and improved their quality of life ( SMD=0.52,95% CI : 0.32 to 0.72, P<0.05). Conclusions Even though the results showed significant improvement in self-efficacy and self-management after interventions, the conclusion needs to be generalised with caution because of the quality of RCTs and high heterogeneity. Future trials could consider RCTs with high quality, appropriate sample size, specific component of diabetes management, and reliable and valid scales or objective measures as outcomes.
RESUMO
Objective@#To explore the long-term efficacy of laparoscopic-assisted anorectoplasty and conventional anorectoplasty in the treatment of children with high and middle anal atresia.@*Methods@#A retrospective cohort study was used. Inclusion criteria: (1) children with high and middle anal atresia; (2) complicated with rectourethral or rectovesical fistula; (3) complete follow-up data. Exclusion criteria: (1) complicated with 21-trisomy; (2) cerebral palsy and other mentaldisabilities; (3) Currarino syndrome; (4) FG syndrome. Clinical data of 88 patients with middle and high anal atresia, who complicated with rectourethral fistula or rectovesical fistula, and underwent anoplasty at Department of Pediatric Surgery, the First Affiliated Hospital of Zhengzhou University from January 2009 to June 2014 were enrolled in the study and analyzed. There were 24 cases with middle atresia and 64 cases with high atresia. All the cases were divided into 2 groups based on the operative method: laparoscopic group (laparoscopic-assisted anorectoplasty, 49 cases), pena group (posterior sagittal anorectoplasty, 39 cases). The demographic features of two groups were comparable. There were no statistically significant differences in gender, age, body mass, classification of anomaly types and sacral ratio (all P>0.05). Student t test and Chi square tests were used to compare the surgical conditions (operative time, postoperative hospital stay and complications), anal function (Kelly score), constipation (Krickenbeck constipation score) and anorectal pressure.@*Results@#Children of both groups all completed operation ssuccessfully. There were no statistically significant differences between laparoscopic group and pena group in the operative time [(120±31) minutes vs. (112±23) minutes, t=1.343, P=0.091] and postoperative hospital stay [(7.1±2.3) days vs. (10.7±3.3) days, t=6.021, P=1.000]. Complications were more common in the pena group [16.3% (8/49) vs. 35.9% (14/39), χ2=4.436, P=0.035]. The main complications in laparoscopic group were anal prolapse (8.2%, 4/49) and anal stenosis (6.2%, 3/49), while in pena group were anal stenosis (12.8%, 5/39) and perioperative perianal skin erosion (10.3%, 4/39). As for the anal function, the degree of feces, defecation control and sphincter contractility, the single scoring differences of Kelly scoring system were not statistically significant between the two groups, but the proportion of good function in the laparoscopic group was higher than that in the pena group [67.3% (8/49) vs. 38.5% (15/39), χ2=7.308, P=0.007]. Constipation occurred in 6 (12.2%) patients in the laparoscopic group, of whom 5 were improved by diet regulation and 1 required laxatives, while 9 (23.1%) patients developed constipation in the pena group, of whom 4 were improved by diet regulation and 5 required long-term laxatives. The difference of constipation ratio was not statistically significant (χ2=1.802, P=0.180). There were no cases of Krickenbeck constipation grade 3. Compared to the pena group, the laparoscopic group had higher anal resting pressure [(33.35±9.69) mmHg vs. (27.68±10.74) mmHg, t=2.599, P=0.011], higher dilating pressure [(9.00±5.61) mmHg vs.(6.51±3.24) mmHg, t=2.462, P=0.016], higher maximal squeeze pressure [(65.80±17.23) mmHg vs. (56.74±18.93) mmHg, t=2.389, P=0.019] and longer maximal contraction time [(21.16±5.02) seconds vs. (18.44±7.24) seconds, t=2.079, P=0.041]. The rectal resting pressure [(5.36±3.00) mmHg vs. (4.61±3.93) mmHg, t=1.015, P=0.312] was not statistically significantly different.@*Conclusions@#Compared with posterior sagittal anorectoplasty, laparoscopic-assisted anorectoplasty in the treatment of high and middle anal atresia has better long-term efficacy with less perioperative complications.

Objective To explore the prognostic effect of hyperintense vessel sign (hyperintense vessel sign,HVS) in fluid-attenuated inversion recovery (FLAIR) on endovascular recanalization of acute ischemic stroke.Methods The clinical and imaging data of the patients with acute middle cerebral artery (MCA) occlusion treated by endovascular therapy from January 2013 to october 2015 were analyzed retrospectively.The inclusion criteria:(1)<8 h after symptom onset;(2) The preoperative MRI included conventional non-enhanced MR,FLAIR,diffusion-weighted imaging (DWI),magnetic resonance angiography (MRA) and DWI-ASPECTS (Alberta Stroke Program Early CT Score) ≥7;(3) acute MCA occlusion verified by conventional angiography and recanalizations (TICI score of 2b and 3) were obtained after endovascular therapy;(4) postoperative similar MR examinations were performed within one week.The patients were divided into group A (HVS score<5) and B (HVS score≥5).The clinical outcomes and radiological characteristics were compared between two groups.Results There were 15 patients in group A and 33 patients in group B.No significant differences were noted in onset-to-MRI interval (4.8±0.7 h vs 4.6± 0.6 h),MRI-to-recanalization interval (2.1 ±0.5 h vs 2.2±0.5 h) and preoperative DWI-ASPECTS score (7.8± 0.9 score vs 8.2± 1.0 score) between the two groups (all P>0.05).Significant differences were noted in NIHSS score at admission (14.6±2.6 score vs 10.1±2.2 score),grade of collateral circulation (1.6±0.3 score vs 2.4± 0.4 score),postoperative DWI-ASPECTS score (5.6±0.8 score vs 7.3±0.9 score),postoperative extension of DWI-ASPECTS score (2.2±0.4 score vs 0.9±0.2 score),the incidence of cerebral hemorrhage transformation (26.7% vs 12.1%) and mRS score at 3 months (3.2±0.5 score vs 2.3±0.4) score between the two groups (all P<0.05).Conclusion HVS score is clearly associated with collateral circulation and high HVS score indicates better functional outcomes than low HVS score.
RESUMO
Objective To build a more perfect serum protein ifngerprint models for early diagnosis of ganglioneuroblas-toma (GNB) in children. Methods Thirty children with GNB and 30 normal control children were recruited. Serum samples were collected. Nonspeciifc serum protein was detected and studied by MB-WCX processing, SELDI-TOF-MS mass spectrom-etry system and MALDI-TOF/TOF platform. Results Through the SELDL-TOX-MS processing, a peak at 5920 m/z protein markers, and the expression of the markers was high in GNB children (6180.6±2328), compared with normal control children (419.1±493.3), the difference was statistically signiifcant (P<0.05);MALDI-TOF/TOF platform showed that the protein with a peak at 5920 m/z is identiifed as ApoC-Ⅲ. Conclusions m/z peak of 5920 protein is suggested as speciifc biomarker of GNB in children, can provide signiifcant reference for early diagnosis of ganglioneuroblastoma, and prognostic monitoring.
RESUMO
Objective To explore the determination of urinary angiotensinogen (uAGT) in the urine of children with obstructive hydronephrosis and its relationship with impaired renal function, to provide a new and rapid reference index for the preoperative evaluation and postoperative follow-up of the children with hydronephrosis.Methods The data were collected from 48 children who were diagnosed as unilateral congenital renal pelvis and ureter obstruction in the outpatient or inpatient Department of Pediatric Surgery of the First Affiliated Hospital of Zhengzhou University,which were divided into operation group and non-operation group.There were 28 children in operation group(who were all severe hydronephrosis) ,who were all operated with dismembered pyeloplasty.There were 20 children in the non-operation group (who were all mild and moderate hydronephrosis).They temporarily had no surgery signs and hydronephrosis did not become increasingly serious for assuring the regular outpatient follow-up after being diagnosed as hydronephrosis;there were 20 children in the control group, 10 of which were male, and 10 female.The males were hospitalized children with hydrocele and the females were with inguinal hernia.Gender composition among the 3 groups, and the average age difference was not statistically significant.The clean urina of children in 3 groups was collected,3 times for operation group, once before operation and once in 6 weeks and once in 12 weeks after operation;3 times for non-operation group and control group with interval of 6 weeks in outpatient clinic.The children in operation group and non-operation group were all scanned for glomerular filtration rate (GFR) of diseased renal with radionuclide;enzyme-linked immunosorbent assay (ELISA) was adopted to determine the content of uAGT in the urine of the 3 groups of children, and automatic biochemical analyzer was used to measure the amount of urine creatinine (uCr).Results Before operation, in 6 weeks and 12 weeks after operation, uAGT / uCr average water of non-operation group and control group was significantly lower than the operation group, all the differences were statistically significant (F =34.360,14.683,5.035, all P < 0.05).Preoperative and postoperative uAGT / uCr and GFR of diseased renal were of negative correlation(r =-0.647,-0.786, all P < 0.05).In operation group, the preoperative and postoperative GFR average of diseased renal was 37.18 ± 7.31 and 45.27 ± 8.18.The difference of GFR changes was statistically significant before and after treatment (t =-3.971, P =0.000).Conclusions uAGT/uCr increased evidently in congenital renal pelvis and ureter obstruction patients who needed operation, so increase of uAGT might be the indicator of impaired renal function caused by obstructive hydronephrosis of children.
RESUMO
<p><b>BACKGROUND</b>Large animal cardiopulmonary bypass (CPB) models are expensive, and prevent assessment of neurocognitive function, and difficulties with long-term recovery. The purpose of this study was to establish a novel rat model of cardiopulmonary bypass for deep hypothermic circulatory arrest without blood priming.</p><p><b>METHODS</b>Twenty adult male Sprague-Dawley rats weighing 450-560 g were randomized to CPB with deep hypothermic circulatory arrest (DHCA) and control groups, with 10 rats each. The experimental protocols, including blood and crystalloid fluid administration, anesthesia, orotracheal intubation, ventilation, cannulation, and heparinization were identical in both groups. After inducing cardiac arrest, the circuit was turned off and rats were left in a DHCA state for 15 minutes. Rats were rewarmed to 34°C to 35°C over a period of 36 to 42 minutes using CPB-assisted rewarming, a heating blanket, and a heating lamp along with administration of 0.1 mEq of sodium bicarbonate and 0.14 mEq of calcium chloride. The remaining priming volume was reinfused and animals were weaned from CPB.</p><p><b>RESULTS</b>All CPB with DHCA processes were successfully achieved. Blood gas analysis and hemodynamic parameters were in the normal range. The vital signs of all rats were stable.</p><p><b>CONCLUSIONS</b>Our CPB circuit has several novel features, including a small priming volume, active cooling/rewarming processes, vacuum-assisted venous drainage, peripheral cannulation without thoracotomy or sternotomy, and an accurate means of monitoring peripheral tissue oxygenation.</p>
