ABSTRACT
ObjectiveThe study aims to determine whether the horizontal posterior displacement of the distal clavicle in patients with acromioclavicular joint dislocation can be corrected via the application of modified intraoperative axillary fluoroscopy. MethodsFrom February 2019 to April 2021， 50 patients with Rockwood type Ⅲ acromioclavicular joint dislocation eligible for inclusion were randomly divided into two groups： the normal （32 cases） and the experimental （18 cases）. The conventional anteroposterior position radiographs were obtained to detect the surgery effect on the patients in the normal group. In experimental group， modified intraoperative axillary radiographs were obtained， with the concept of polar coordinates introduced to reduce the horizontal posterior translation of the clavicle. Then we compared the perioperative parameters， such as average operative time， intraoperative blood loss between the two groups. The Constant score was used for assessing the postoperative function of the shoulder joint in the follow-up visits. ResultsNo statistically significant difference was found in gender， age， duration of injury， underlying diseases， intraoperative blood loss and operative time between the two groups. The postoperative shoulder function score of the experimental group was higher than that of the normal group. ConclusionsThe application of modified intraoperative axillary fluoroscopy is recommendable for accurately reducing posterior translation of the distal clavicle， and meanwhile helpful for the precise placement of the clavicular plate.
ABSTRACT
AIM: To observe the efficacy of moderate and high myopia patients with vault greater than 1 000μm after implantation of phakic posterior chamber implantable contact lens(ICL).METHODS: A total of 42 patients(73 eyes)who received ICL implantation in the hospital and had postoperative vault greater than 1 000 μm between January 2014 and January 2017 were selected and retrospectively studied. Changes in visual acuity, intraocular pressure, corneal endothelial cell density, anterior chamber-related parameters(chamber angle, central anterior chamber depth, anterior chamber volume)and vault were compared among patients before surgery, at 1, 3, 6mo and 1a after surgery and at the last follow-up.RESULTS: The uncorrected visual acuity(UCVA)at 1, 3, 6mo and 1a after surgery and at the last follow-up was better than that before surgery(all P<0.05), and the chamber angle, central anterior chamber depth and anterior chamber volume were smaller or lower than those before surgery(all P<0.05), but there were no statistical differences in UCVA, chamber angle, central anterior chamber depth and anterior chamber volume at each time point after surgery(all P>0.05). The intraocular pressure at 1mo after surgery was lower than that before surgery(P<0.05), but the intraocular pressure at 3, 6mo and 1a after surgery and at the last follow-up was not statistically different from that before surgery(all P>0.05). There was no statistical significance in the corneal endothelial cell density at 1, 3, 6mo and 1a after surgery and at the last follow-up compared with that before surgery(all P>0.05). The vault at 1, 3, 6mo and 1a after surgery and at the last follow-up showed a decreasing trend, and the difference was statistically significant at each time point after surgery(all P<0.05).CONCLUSION: The short-term and long-term efficacy are better in moderate and high myopia patients with vault greater than 1 000 μm after ICL implantation, and there are no significant effects on the intraocular pressure and corneal endothelial cell. The postoperative anterior chamber structure is relatively stable and the vault tends to decrease over time. In most cases, close observation is sufficient and intraocular lens replacement is generally not required.
ABSTRACT
Objective To assess the clinical characteristics of acute-on-chronic liver failure in patients with recompensatory hepatitis B cirrhosis. Methods A total of 180 patients with acute-on-chronic liver failure hospitalized in Tianjin Third Central Hospital from September 2013 to September 2021 were retrospectively collected, with 110 patients had compensatory hepatitis B cirrhosis and 70 patients had compensatory hepatitis B cirrhosis and used as the control. Their causes, clinical biochemical indicators, complication rate, and prognosis were compared. The Chi-square test or Fisher's exact test was used for comparison of categorical variables between groups, and the Mann-Whitney U test was performed for analysis of the continuous variables. Kaplan-Meier curves and Log-rank test were used for survival of patients. Results The incidence of hepatorenal syndrome ( χ 2 =4.618, P =0.032), infection ( χ 2 =6.712, P =0.010), Cr ( Z =-4.508, P < 0.001), and PCT ( Z =-2.052, P =0.040) were all higher, whereas GGT ( Z =-2.042, P =0.041), Na ( Z =-2.001, P =0.045), FBS ( Z =-3.065, P =0.002), and TC ( Z =-4.268, P < 0.001) were all lower in the recompensation group than in the control group of patients. However, 90-day mortality rate ( χ 2 =3.366, P =0.067) and 1-year mortality rate ( χ 2 =1.893, P =0.169), 90-day survival ( χ 2 =2.68, P =0.100), and 1-year survival ( χ 2 =2.074, P =0.150) were not statistically significant difference. Conclusion Compared with compensatory hepatitis B cirrhosis, patients with recompensatory cirrhosis had an increased risk in developing hepatorenal syndrome, infection, and increased creatinine level after acute-on-chronic liver failure, although there was no statistically significant difference in 90-days and 1-year survival of patients.
ABSTRACT
@#Objective To assess the safety and clinical outcomes of segmentectomy in one- or two-staged video-assisted thoracoscopic surgery (VATS) for bilateral lung cancer. Methods We retrospectively enrolled 100 patients who underwent VATS segmentectomy for bilateral lung cancer at the Department of Thoracic Surgery of Peking Union Medical College Hospital from December 2013 to May 2022. We divided the patients into two groups: a one-stage group (52 patients), including 17 males and 35 females with a mean age of 55.17±11.09 years, and a two-stage group (48 patients), including 16 males and 32 females with a mean age of 59.88±11.48 years. We analyzed multiple intraoperative variables and postoperative outcomes. Results All 100 patients successfully completed bilateral VATS, and at least unilateral lung received anatomical segmentectomy. Patients in the one-stage group were younger (P=0.040), had lower rate of comorbidities (P=0.030), were less likely to have a family history of lung cancer (P=0.018), and had a shorter interval between diagnosis and surgery (P=0.000) compared with patients in the two-stage group. Wedge resection on the opposite side was more common in the one-stage group (P=0.000), while lobectomy was more common in the two-stage group. The time to emerge from anesthesia in the one-stage group was longer than that in the first and second operations of the two-stage group (P=0.000, P=0.002). Duration of surgery and anesthesia were similar between two groups (P>0.05). Total number of lymph node stations for sampling and dissection (P=0.041) and lymph nodes involved (P=0.026) were less in the one-stage group. Intraoperative airway management was similar between two groups (P>0.05). The one-stage group was associated with lower activities of daily living (ADL) scores. Conclusion Segmentectomy is safe in one- or two-staged VATS for bilateral lung cancer, including contralateral sublobectomy and lobectomy. Duration of surgery and perioperative complications are similar between two groups, but the one-stage group is associated with lower ADL scores. On the basis of comprehensive consideration in psychological factors, physical conditions and personal wishes of patients, one-staged sequential bilateral VATS can be the first choice.
ABSTRACT
Objective:To analyze the predictive ability of model for end-stage liver disease (MELD)-sarcopenia score in short-term prognosis of patients with acute-on-chronic liver failure (ACLF).Methods:Two hundred and seventy-one patients with ACLF hospitalized in Tianjin Third Central Hospital from January 2013 to December 2019 were selected, among whom 157 cases with sarcopenia and 114 cases without sarcopenia.According to ACLF classification, the patients were divided into group A (no cirrhosis basis) of 61 cases, group B (compensated cirrhosis basis) of 99 cases, and group C (previous history of uncompensated cirrhosis) of 111 cases.The basic data, laboratory examination results, computed tomography (CT) examination results and prognosis of the patients were retrospectively collected, and the MELD score, MELD-Na score and MELD-sarcopenia score were calculated. Multivariate logistic regression, multivariate Cox proportional hazards regression, Kaplan-Meier method, log-rank method and area under receiver operating characteristic curve were used for statistical analysis.Results:Low body mass index (odds ratio ( OR)=0.93, P<0.001), complicated cirrhosis ( OR=1.14, P=0.004), complicated hepatic encephalopathy ( OR=1.31, P<0.001), high white blood cell level ( OR=1.18, P=0.009) and high platelet level ( OR=1.08, P<0.001) were independent risk factors for sarcopenia in patients with ACLF. High MELD score (hazard ratio ( HR)=1.02, P=0.001), high MELD-Na score ( HR=1.07, P=0.038), high MELD-sarcopenia score ( HR=1.14, P<0.001), high total bilirubin ( HR=1.00, P<0.001) and high international normalized ratio (INR) ( HR=1.71, P<0.001) were independent risk factors for death in patients with ACLF. In subgroup analysis, the cumulative survival rate of sarcopenia patients in group A and B was lower than that of non-sarcopenia patients ( χ2=5.97 and 8.34, respectively, P=0.015 and 0.004, respectively), while there was no significant difference in the cumulative survival rate between sarcopenia patients and non-sarcopenia patients in group C ( χ2=4.90, P=0.053). In groups A and B, the area under the curve (AUC) of MELD-sarcopenia score in predicting short-term prognosis was 0.87, which was higher than MELD score (0.78) and MELD-Na score (0.78), and the differences were both statistically significant ( Z=2.86 and 2.56, respectively, P=0.004 and 0.011, respectively). The AUC of MELD-Na score in predicting short-term prognosis in group C (0.83) was higher than that of MELD score (0.71) and MELD-sarcopenia score (0.69), and the differences were both statistically significant ( Z=2.52 and 2.64, respectively, P=0.012 and 0.008, respectively). Conclusions:Patients with ACLF with no cirrhosis basis or compensated cirrhosis basis complicated with sarcopenia have shorter survival time and worse prognosis than those without sarcopenia. For patients with ACLF with no cirrhosis basis or compensated cirrhosis basis, MELD-sarcopenia score has better predictive value for the short-term prognosis.
ABSTRACT
Objective:To explore the effect of repetitive transcranial magnetic stimulation (rTMS) combined with cognitive behavioral therapies (CBT) on the cognitive function and alcohol craving in patients with alcohol dependence.Methods:From March 2019 to September 2021, a total of 150 patients with alcohol dependence were enrolled and randomly divided into rTMS treatment group (rTMS+ sham CBT, n=41), CBT treatment group (CBT+ sham rTMS, n=34), rTMS+ CBT treatment group( n=36) and control group (sham rTMS+ sham CBT, n=39). At baseline (before treatment), 2nd week, 8th week, 12th week and 24th week, alcohol dependence scale (ADS) was used to evaluate the degree of alcohol dependence, the obsessive compulsive drinking scale (OCDS) was used to assess patients' drinking craving, and Montreal cognitive assessment scale (MoCA) was used to assess the overall cognitive level of patients.SPSS 23.0 statistical software was used to compare the differences of ADS, OCDS and MoCA scale scores of the four groups by repeated measure ANOVA and simple effect analysis. Results:(1)The patients in the four groups were evaluated with ADS scale at baseline, 12th week and 24th week respectively.The interaction of group×time( F=1.279, P=0.279) and the main effect of group were not significant ( F=0.882, P=0.454), and the main effect of time was significant ( F=12.925, P<0.001) .Further simple effect analysis showed that the ADS score of rTMS+ CBT group was lower than that of baseline(14.48±5.70, 10.00±6.51) ( P=0.01) at 24th week.(2)Patients in the four groups were assessed with OCDs scale at baseline, 2nd week, 8th week, 12th week and 24th week, and the interaction of group×time was significant ( F=2.015, P=0.042). Further simple effect analysis showed that the OCDs scores of rTMS group and rTMS+ CBT group at each follow-up time node were lower than those at baseline period (all P<0.05). (3)Patients in the four groups were assessed with MoCA scale at baseline, 8th week, 12th week and 24th week, and the interaction of group×time was not significant ( F=1.660, P=0.106), and the main effect of group and the main effect of time were significant ( F=2.964, P=0.038; F=14.239, P<0.001). Further simple effect analysis showed that the score of MoCA scale in CBT group at the 24th week was higher than that at baseline (21.73±5.81, 24.60±3.98)( P=0.029), the score of MoCA scale in rTMS+ CBT group at the 24th week was higher than that at the 8th week (23.50±6.01, 25.95±2.87) ( P=0.006), and the score of MoCA scale in rTMS group at the 12th week was higher than that in control group (22.08±6.64, 26.64±2.46)( P=0.009). Conclusion:rTMS combined with CBT can be effective in improving alcohol craving and cognitive function in patients with alcohol dependence, and has a good long-term effect.

ABSTRACT
Complement is an important element of immune system playing vital roles in immune surveillance and tissue homeostasis. Increasing evidence shows that complement activations not only protect the body, but contribute to the occurrence and development of autoimmune diseases. Inappropriate activations of complement may also lead to or aggravate various neuro-immunological diseases, including neuromyelitis optica spectrum disease, myasthenia gravis and Guillain-Barré syndrome. Several complement-targeted therapeutics have emerged in recent years, established themselves as popular clinical research topics associated with various autoimmune diseases. Following that note, this review introduces mechanisms of complements participating in autoimmune diseases of the nervous system and the latest development of complement-targeted therapeutics, with the view to contributing to the development of this emerging therapeutic field.
ABSTRACT
Objective:To explore the clinical efficacy of vascular interventional therapy in children with transplantation renal artery stenosis(TRAS).Methods:From January 2013 to September 2021, retrospective analysis was performed for clinical data of 238 TRAS children.Peak systolic velocity(PSV)of transplant renal artery, interlobular artery PSV, transplant renal artery PSV/ interlobular artery PSV(post PSV ratio)and serum creatinine level before and after vascular interventional therapy and at the last follow-up were compared.Results:Six pediatric kidney transplantation recipients were diagnosed as TRAS.The median operative age was 12(9-17)years, the median postoperative time to diagnosing TRAS 4(1.7-18.0)months and the median follow-up period 6.6(2.5-8.0)years.All of them received vascular interventional therapy of percutaneous transluminal angioplasty(PTA, n=5)and stent angioplasty( n=1). The serum creatinine pre-treatment with vascular interventional therapy was significantly higher than baseline serum creatinine level at discharge(200.8±88.5)vs(75.2±27.9)μmol/L, P=0.025 and decreased to(103.8±44.7)μmol/L at Month 1 post-treatment( P=0.196)and(98.7±30.2)μmol/L at the last follow-up( P=0.115). Comparing with internal diameter of grafted renal artery anastomosis site(2.6±0.6 mm)pre-treatment with vascular interventional therapy, significant changes occurred at 24 h post-treatment(3.8±0.5 mm)and at the last follow-up(4.1±0.8 mm)(all P=0.027). In addition, PSV and post PSV ratio of transplanted renal artery at 24 h post-treatment(163±45.0 cm/s, 6.5±2.2)and at the last follow-up(184.7±80.8 cm/s, 5.4±2.0)were significantly lower than that before vascular interventional therapy(356.5±77.9 cm/s, 18.0±5.8)and interlobular artery PSV was significantly higher than that before vascular interventional therapy( P=0.024, P=0.032, respectively). During follow-ups, no restenosis or thrombosis occurred in transplanted renal arteries. Conclusions:PTA or stent angioplasty for TRAS children is technically feasible with low restenosis rate and relatively satisfactory mid/long-term outcomes.
ABSTRACT
ObjectiveTo explore the mechanism of Cordyceps in treating bronchial asthma and chronic renal failure with the concept of "same treatment for different diseases" in traditional Chinese medicine （TCM） by network pharmacology and molecular docking technology. MethodThe active components and potential targets of Cordyceps were collected from Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP） and SwissTargetPrediction. The disease targets were obtained from Therapeutic Target Database （TTD）， DrugBank， GeneCards and other databases. The common targets were obtained from the intersection of potential targets and disease targets. The protein-protein interaction （PPI） network was constructed by STRING11.5， and the ''component-target-diseas'' network of Cordyceps was established by Cytoscape 3.9.0. Gene Ontology （GO） and Kyoto Encyclopedia of Genes and Genomes （KEGG） enrichment analyses were carried out by Metascape， and molecular docking was performed by Autodock 4.2. ResultSixty common targets of disease and drug were screened out. The core targets mainly involved protein kinase B1 （Akt1）， non-receptor tyrosine kinase， sarcoma virus protein （SRC）， TP53， matrix metalloproteinase-9 （MMP-9）， and prostaglandin endoperoxide synthase 2 （PTGS2）. The potential targets were mainly enriched in the signaling pathways of renin-angiotensin system （RAS）， RAP1， phosphoinositide 3 kinase/protein kinase B （PI3K/Akt）， mitogen-activated protein kinase （MAPK）， etc. ConclusionThe active components of Cordyceps inhibited inflammatory response and reduced fibrosis and cell apoptosis in a multi-target and multi-pathway manner. The findings of this study preliminarily revealed the potential targets and modern biological mechanism of Cordyceps in treating bronchial asthma and chronic renal failure with the concept of ''same treatment for different diseases''， and provided references for in-depth experimental verification and clinical application.
ABSTRACT
ObjectiveTo explore the mechanism of antidepressant effect of lily polysaccharide （LLP）and astragalus polysaccharide（APS）. MethodSixty KM mice were randomly divided into blank group， model group， fluoxetine hydrochloride （8 mg·kg-1）group， LLP （0.2 g·kg-1）group， APS （0.2 g·kg-1）group and polysaccharide combination （LLP+APS，0.1 g·kg-1+0.1 g·kg-1）group， with 10 mice in each group. Except the blank group， the other groups were given chronic unpredictable mild stress （CUMS） induced mouse depression model. On the 29th day of modeling，fluoxetine hydrochloride group was given corresponding dose of fluoxetine hydrochloride， and polysaccharide groups were given corresponding drug. The depressive behavior of mice was evaluated by behavioral indexes such as body mass change， open field test. The morphological changes of hippocampal CA1 neurons were observed by Nissl staining. The contents of 5-hydroxytryptamine （5-HT）， adrenocorticotropic hormone （ACTH）， and corticosterone （CORT）， in brain tissue and plasma were measured by enzyme-linked immunosorbent assay （ELISA）. Western blot was used to detect the expression levels of related proteins in adenylate cyclase/cyclic adenylate phosphate/protein kinase A （AC/cAMP/PKA） signal pathway. ResultCompared with the blank group， mice in the model group gained weight slowly， the total distance， central distance and sugar water preference rate decreased significantly （P<0.01）， the depressive behavior was significant， the hippocampal neurons were seriously damaged， the content of 5-HT decreased （P<0.01）， the contents of ACTH and CORT increased significantly （P<0.01）， adenylate cyclase 6（ADCY6）， PKA and cAMP response element binding protein-1 （CREB-1） and brain-derived neurotrophic factor （BDNF） protein expression decreased significantly （P<0.01）. Compared with the model group， depressive behavior of mice in LLP group， APS group and LLP+APS group was significantly improved （P<0.01）. The antidepressant effect of LLP+APS was better than that of LLP and APS. Each administration group could alleviate the damage of hippocampal neurons in varying degrees， significantly increase the content of 5-HT in brain tissue （P<0.01）， and reduce the levels of ACTH and CORT in plasma （P<0.05）. The protein levels of ADCY6， PKA， CREB-1 and BDNF were significantly increased （P<0.05）. ConclusionThe antidepressant effect of LLP+APS is significantly enhanced and has a synergistic effect. The mechanism may be closely related to affecting the content of neurotransmitters， inhibiting HPA axis activity and activating AC/cAMP/PKA signal transduction pathway.
ABSTRACT
Pulmonary inflammatory myofibroblastic tumor (PIMT) is a rare lung tumor that is poorly understood by clinicians. Based on the data of patients with PIMT in our center, a comprehensive search and a brief summary analysis of previous reports of the disease were carried out in this article. PIMTs were more likely to be present in male patients and in the right lung, and their clinical and radiographic findings were heterogeneous. Surgery is the most important treatment method, and complete resection is of great significance to the prognosis of patients. Targeted therapy represented by crizotinib may be helpful for patients with positive ALK mutations.
ABSTRACT
Objective:To document the blood indexes of middle-aged and elderly intracerebral hemorrhage (ICH) patients complicated with deep vein thrombosis (DVT).Methods:A retrospective analysis was conducted of 77 hospitalized ICH patients using venous color Doppler ultrasonography within 3 days of admission. According to the results, they were divided into a DVT group (18 cases) and a non-DVT group (59 cases). The blood routine, biochemistry, coagulation, and D-dimer examinations were conducted on the 2nd day after admission. T-tests and rank sum tests tested the significance of any differences between the groups in average white blood cell counts, neutrophil percentages, platelets, albumin, globulin, fasting blood glucose, urea nitrogen, creatinine, uric acid, electrolytes, fibrinogen or D-dimer.Results:The average levels of albumin, uric acid and calcium in the DVT group were significantly lower than in the non-DVT group. The average levels of fasting blood glucose and D-dimer were significantly higher.Conclusions:Decreased serum uric acid, calcium and albumin levels, together with increased fasting blood glucose and D-dimer are related to the occurrence of DVT in ICH patients. To reduce the risk of DVT it is important to maintain normal levels of serum uric acid, calcium and albumin and to limit D-dimer and fasting blood glucose.
ABSTRACT
Objective:To investigate the feasibility of "twelve-section ultrasonic screening diagnosis method" in screening for neonatal complex congenital heart disease (CHD) in primary hospitals.Methods:This is a prospective study. A total of 71 580 newborns were screened for CHD using the "twelve-section ultrasonic screening diagnosis method" from four pilot units in Hebei province, which were Bo'ai Hospital of Huanghua Development Zone, Traditional Chinese Medicine Hospital of Fengning County, Maternity & Child Healthcare Hospital of Tang Country, and Maternity & Child Healthcare Hospital of Rongcheng Country, from November 2015 to December 2019. Another 262 children with CHD were enrolled, including 39 with complex CHD. These cases received ultrasonography at four pilot units above and then were transferred to CHD Screening Diagnosis and Treatment Center of Hebei Children's Hospital (our center) prior to the implementation of "twelve-section ultrasonic screening diagnosis method" from June 2012 to June 2014, who were all confirmed by surgery. Set the diagnosis results of our center as the gold standard, the sensitivity, specificity, and diagnostic consistency rate in screening for complex CHD cases were calculated. Receiver operating characteristic (ROC) analysis and Chi-square test were used to compare and analyze the sensitivity for screening neonatal complex CHD before and after implementing the method. The screening results of complex CHD after implementing the method between the pilot units and our center as well as between the four pilot units were compared and analyzed using Chi-square test. Results:A total of 553 (0.77%) CHD cases were detected by the "twelve-section ultrasound screening diagnosis method", including 66 cases of complex CHD and 487 cases simple CHD. Among the cases screened using the method, there were three false negative cases (one case with total anomalous pulmonary venous drainage, one with abnormal coronary artery originating from pulmonary artery, and one with atresia of distal to the left subclavian artery, aortic arch and left aortic arch of double-arch), one false positive case (false echo loss of aortopulmonary septal that was misdiagnosed as aortopulmonary septal defect), five cases of misdiagnosis (one common pulmonary venous atresia case that was misdiagnosed as total anomalous pulmonary venous drainage, one persistent stenosis of the fifth aortic arch that was misdiagnosed as coarctation of aorta, one pulmonary artery sling that was misdiagnosed as absence of left pulmonary artery, one severe coarctation of aorta that was misdiagnosed as interruption of aortic arch, and one aortic isthmus atresia that was misdiagnosed as coarctation of aorta), and all were complex CHD cases. A total of 68 cases (12.3%) of complex CHD were confirmed by our center. The overall sensitivity, specificity, and diagnostic consistency rate of screening were 95.6% (65/68), 99.8% (484/485), and 86.8% (59/68), respectively and the area under ROC curve was 0.98. Before the implementation, the overall sensitivity, specificity, and diagnostic coincidence rates of ultrasonic screening for complex CHD were 69.2%(27/39), 95.5%(213/223), and 61.5% (24/39), respectively, and the area under ROC curve was 0.82. The sensitivity of complex CHD screening was significantly increased after implementing the method ( χ2=14.28, P<0.05). There was no significant statistical significance in the sensitivity for screening complex CHD after the implementation between the pilots and our center or between the four pilots (all P>0.05). Conclusions:"Twelve-section ultrasonic screening diagnosis method" is suitable for the screening of neonatal complex CHD in hospitals at the county level. However patients with some special types of complex CHD are recommended to be transferred for a more accurate diagnosis.
ABSTRACT
Objective:To investigate the effect of optimizing perioperative measures on reducing postoperative gastric emptying disorder in gastrointestinal reconstruction after pancreaticoduodenectomy.Methods:The clinical data of 146 patients who underwent pancreaticoduodenectomy from Jan 2019 to Dec 2020 at the Department of Hepatobiliary and Pancreatic Surgery,the First Affiliated Hospital ,Anhui Medical University were analyzed retrospectively. Among them, 78 cases underwent traditional Billroth Ⅱ gastrojejunal anastomosis for gastrointestinal reconstruction, and 68 cases in the improvement group took optimization measures. The time to first postoperative flatus, time to oral intake, postoperative hospital stay and complications were observed.Results:The operation time in the control group was (351.4±71.6) min, less than that in the improved group (368.8±97.6) min, while the time [(9.9±6.5)d vs. (7.6±6.0)d] to first oral take and postoperative hospital stay [(20.7±8.6)d vs. (17.9±7.0)d] were significantly longer than those in the improved group. The incidence of postoperative gastric emptying disorder (19.2% vs. 7.4%) was significantly higher than that in the improved group ( P<0.05). There was no significant difference in postoperative time to first flatus and postoperative gastrointestinal bleeding between the two groups (all P>0.05). Conclusions:The measures of optimizing gastrointestinal reconstruction in the perioperative period of pancreaticoduodenectomy have obvious advantages in reducing gastric emptying disorder, promoting the recovery of gastrointestinal function and shortening the length of hospital stay.
ABSTRACT
Objective To investigate the differences in platelet and platelet parameters between patients with different types and etiologies of acute-on-chronic liver failure (ACLF) and the influence of platelet and its dynamic change on the prognosis of ACLF patients. Methods Clinical data, liver function parameters, platelet, and platelet parameters were collected from 364 patients with ACLF who attended Tianjin Third Central Hospital from January 2014 to December 2018. Platelet level and platelet parameters (platelet distribution width and mean platelet volume) were compared between the patients with different types and etiologies of ACLF, and their influence on the 90-day mortality rate of ACLF patients was analyzed, as well as the association of the dynamic change of platelet at baseline and on days 7 and 14 after admission with the prognosis of patients. The chi-square test was used for comparison of categorical data between groups; the Kruskal-Wallis H test or Mann-Whitney U test was used for comparison of continuous data between groups; the Kaplan-Meier method was used for survival analysis; the univariate and multivariate Cox regression analyses were used to analyze the parameters associated with prognosis; the repeated measures analysis of variance was used to analyze the dynamic change of platelet; receiver operating characteristic (ROC) curve was plotted based on platelet level and overall survival. Results The patients with type C ACLF had a significantly lower platelet level than those with type A/B ACLF (all P < 0.001). Compared with the ACLF patients with hepatitis B, the ACLF patients with autoimmune liver diseases had a significant reduction in mean platelet volume ( P =0.035). Based on the cut-off value obtained by the ROC curve analysis, the patients with a platelet level of < 60.5×10 9 /L had a significantly higher mortality rate than those with a platelet level of ≥60.5×10 9 /L ( P =0.006). Platelet level was an independent protective factor against 90-day death in ACLF patients (hazard ratio=0.995, 95% confidence interval: 0.990-0.999, P =0.026), and the mortality rate increased with the reduction in platelet level. The patients with type C ACLF had a significantly higher mortality rate than those with type A ACLF ( P < 0.05), and the death group tended to have a significantly greater reduction in platelet level ( P < 0.05). Compared with the survival group, the 90-day death group had a significantly greater reduction in platelet ( P =0.032). Conclusion There is a difference in platelet level between ACLF patients with different types. Platelet level is an important indicator for the 90-day prognosis of ACLF patients, and patients with a greater dynamic reduction in platelet tend to have a higher 90-day mortality rate.
ABSTRACT
Objective:To compare the diagnostic efficacy of 18F-prostate specific membrane antigen (PSMA)-1007 PET/CT and mpMRI in the diagnosis of pelvic lymph node metastasis of prostate cancer (PCa). Methods:The clinical data of 30 patients who underwent 18F-PSMA-1007 PET/CT and mpMRI examinations in Sichuan Cancer Hospital from November 2018 to April 2021 were analyzed. The average age was (68.4±6.4) years old. The preoperative total PSA was 45.70(16.07, 100.00)ng/ml. Among 30 patients, 14 cases were found lymph node positive by PET/CT and 7 cases were found lymph node positive by mpMRI.Combined with the two preoperative imaging methods and the patient's PSA level, there was 1 patient in stage T 1, 20 patients in stage T 2, 6 patients in stage T 3, and 3 patients in stage T 4. Twenty-nine cases were classified as high risk group and one case was in moderate risk group.All 30 patients underwent laparoscopic radical prostatectomy and enlarged pelvic lymph node dissection (ePLND). According to the postoperative pathological results, the sensitivity, specificity, positive predictive value and negative predictive value of the two imaging techniques for the diagnosis of PCa pelvic lymph node metastasis were calculated, and the consistency of the two imaging techniques for the postoperative pathological results was observed by Kappa test. Results:All the 30 patients were confirmed to be PCa by postoperative pathology, among which 10 patients were positive for pelvic lymph node biopsy. The sensitivity, specificity, positive predictive value and negative predictive value of 18F-PSMA-1007 PET/CT for pelvic lymph node metastasis were 100.0% (10/10), 80.0% (16/20), 71.4%(10/14) and 100.0%(16/16) respectively, and Kappa value was 0.727. The sensitivity and specificity of mpMRI were 70.0% (7/10) and 100.0% (20/20), the positive and negative predictive values were 100.0% (7/7) and 87.0%(20/23)respectively, and the Kappa value was 0.757. The P values of sensitivity, specificity, positive predictive value and negative predictive value between the two imaging methods were 0.18, 0.07, 0.30, <0.01, respectively. The sensitivity, specificity, positive predictive value and negative predictive value of 18F-PSMA-1007 PET/CT in diagnosing the number of pelvic lymph node metastasis were 100%(28/28), 98.2% (373/380), 80.0% (28/35) and 100.0%(373/373), respectively. The sensitivity, specificity, positive predictive value and negative predictive value of mpMRI in diagnosing the number of pelvic lymph node metastasis were 78.6% (22/28), 100.0% (380/380), 100.0% (22/22) and 98.4%(380/386), respectively. The P values of the sensitivity, specificity, positive predictive value and negative predictive value of lymph node detection by the two imaging methods were all <0.01, and the differences were statistically significant. Conclusions:The sensitivity and negative predictive value of 18F-PSMA-1007 PET/CT for the detection of positive lymph node were higher than mpMRI. The specificity and positive predictive value of mpMRI in detecting positive lymph node metastasis were higher than 18F-PSMA-1007 PET/CT examination.
ABSTRACT
Objective:To investigate the clinical characteristics and risk factors for the progression of acute-on-chronic liver failure(ACLF)associated with hepatitis B in elderly patients.Methods:A total of 168 elderly patients with hepatitis B-related acute-on-chronic liver failure(HBV-ACLF)at Tianjin Third Central Hospital who met the diagnostic criteria of the Asian Pacific Association for the Study of the Liver(APASL)-ACLF were enrolled, 176 non-elderly HBV-ACLF patients served as the control group during the same period, and their baseline and progression data were recorded.At the same time, the elderly group was divided into the progressive subgroup and the non-progressive subgroup based on the diagnostic criteria of the European Society for the Study of the Liver(EASL)-ACLF, and their baseline and progression data were recorded.Independent risk factors for HBV-ACLF progression in the elderly were analyzed using multivariate Cox proportional risk model regression.Results:Compared with non-elderly patients with HBV-ACLF, elderly patients were more likely to progress to meet the EASL-ACLF diagnostic criteria and have higher mortality.Multivariate Cox proportional risk model regression analysis showed that baseline arterial lactic acid levels( HR=1.77, 95% CI: 1.36-2.30, P<0.01), secondary nosocomial infections( HR=13.90, 95% CI: 3.73-51.87, P<0.01), rates of change in maximum total bilirubin( HR=1.08, 95% CI: 1.01-1.15, P=0.04), rates of change in maximum MELD( HR=4.06, 95% CI: 1.53-10.77, P=0.01)and rates of change in maximum CLIF-SOFA( HR=12.74, 95% CI: 2.46-66.08, P<0.01)were independent risk factors for progression of HBV-ACLF in elderly patients. Conclusions:Compared with non-elderly patients, elderly patients with HBV-ACLF have more advanced disease and higher mortality.Therefore, risk factors should be identified as soon as possible and treatment plans should be formulated as soon as possible to further reduce the mortality.
