ABSTRACT

To study the time-toxicity relationship and mechanism of Gardeniae Fructus extract on the hepatoxicity in rats. Rats were randomly divided into C group(0 day), D5 group(5 days), D12 group(12 days), D19 group(19 days), and D26 group(7 days recovery after 19 days of administration). The rats in normal group received normal saline through intragastric administration, and the rats in other groups received 10 g·kg~(-1 )Gardeniae Fructus extract through intragastric administration. After the final administration, the livers were collected. Hematoxylin-eosin staining was used to observe the histopathological changes in the liver tissue. Total liver proteins were extracted for proteomic analysis, detected by the Nano-ESI liquid-mass spectrometry system and identified by Protein Disco-very software. SIEVE software was used for relative quantitative and qualitative analysis of proteins. The protein-protein interaction network was constructed based on STRING. Cytoscape software was used for cluster analysis of differential proteins. Kyoto encyclopedia of genes and genomes(KEGG) database was used to perform enrichment signal pathway analysis. Pearson correlation analysis was performed for the screened differential protein expression and liver pathology degree score. The results showed that the severity of liver injury in D5, D12 and D19 groups was significantly higher than that in group C. The degree of liver damage in D5 group was slightly higher than that in D12 and D19 groups, with no significant difference between group D26 and group C. Totally 147 key differential proteins have been screened out by proteomics and mainly formed 6 clusters, involving in drug metabolism pathways, retinol metabolism pathways, proteasomes, amino acid biosynthesis pathways, and glycolysis/gluconeogenesis pathways. The results of Pearson correlation analysis indicated that differential protein expressions had a certain temporal relationship with the change of liver pathological degree. The above results indicated that the severity of liver damage caused by Gardeniae Fructus extract did not increase with time and would recover after drug with drawal. The above pathways may be related to the mechanism of liver injury induced by Gardeniae Fructus extract.

ABSTRACT

We used metabolomics technology to identify and understand the biomarkers and therapeutic mechanisms of umbilical compress therapy based on Xiaozhang Tie (XT) to provide scientific evidence for its clinical application. A total of 10 patients with cirrhotic ascites and gastrointestinal motility disorders who were hospitalized in the Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from November 2017 to June 2018 were divided into a placebo group (4 cases) or an XT group (5 cases), and 10 healthy volunteers were included as controls. This clinical trial was approved according to the Ethics Committee of Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine (2017-528-11-01). The patients in the XT group were given umbilical compress therapy with Xiaozhang Tie, and patients in the placebo group were administered a plaster patch in which the drug content was less than 5%, receiving one patch per day for three consecutive days. Non-targeted metabolomics technology and UPLC-Q/Orbitrap-MS/MS analysis technology were utilized to investigate the fluctuations in endogenous metabolic profiles in the patient's urine prior to and after administration of XT. By analyzing and comparing the urine metabolic profiles of patients with cirrhotic ascites to those of healthy volunteers, a total of 31 biomarkers were identified, 14 of which were significantly decreased by the intervention with Xiaozhang Tie (P <0.05). Pathway enrichment analysis revealed that phenylalanine metabolism and tryptophan metabolism are key pathways affected by XT treatment. The results suggest that XT can alleviate cirrhotic ascites by modulating abnormalities in amino acid metabolism.

ABSTRACT

PURPOSE@#This meta-analysis compared the clinical outcome of three-dimensional (3D) printing combined with open reduction and internal fixation (ORIF) to traditional ORIF in the treatment of acetabular fractures.@*METHODS@#We searched the Cochrane Library, PubMed, Embase, VIP database, CNKI, and Wanfang database with keywords "acetabular fracture", "3D printing", "three-dimensional printing", "open reduction and internal fixation", "Acetabulum", "Acetabula" from January 2000 to March 2020. Two reviewers independently selected articles, extracted data, assessed the quality evidence and risk bias of included trials using the Cochrane Collaboration' s tools and/or Newcastle-Ottawa scale. When the two analysts had different opinions, they would ask the third analyst for opinion. Randomized controlled trials or retrospective comparative studies of 3D printing combined with ORIF (3D printing group) versus traditional ORIF (conventional group) in the treatment of acetabular fractures were selected. The data of operation time, intraoperative blood loss, intraoperative fluoroscopy times, incidence of complications, excellent and good rate of Matta score for reduction, and excellent and good rate of hip function score were extracted. Stata14.0 statistical software was used for data analysis.@*RESULTS@#Altogether 9 articles were selected, including 5 randomized controlled trials and 4 retrospective studies. A total of 467 patients were analyzed, 250 in the conventional group, and 217 in the 3D printing group. The operation time in the 3D printing group was less than that in the conventional group and the difference was statistically significant (standardized mean difference (SMD) = -1.19, 95% CI: -1.55 to -0.82, p  0.05). There was no significant difference in the excellent and good rate of hip function score at the end of postoperative follow-up between the two groups (OR = 0.84, 95% CI: 0.46-1.56, p > 0.05), but the follow-up time varies from 6 months to 40 months.@*CONCLUSION@#Compared with traditional ORIF, 3D printing combined with ORIF has certain advantages in terms that 3D printing not only helps surgeons to understand acetabular fractures more intuitively, but also effectively reduces operation time, intraoperative blood loss, intraoperative fluoroscopy times, and postoperative complications. However, there were no significant differences in the excellent and good rate of Matta score for reduction and the excellent and good rate of hip function score at the end of follow-up.

ABSTRACT

OBJECTIVE@#To analyze the biomechanics of cystic lesions in the mandibular body in a three-dimensional (3D) finite element model.@*METHODS@#A 3D finite element model of cystic lesion of the mandibular body was constructed based on the CT images of the mandible of a healthy adult female volunteer with normal occlusion. The size of the cyst and the residual bone wall were analyzed when the lesion area approached the stress peak under certain constraints and loading conditions.@*RESULTS@#When the size of the cyst reached 37.63 mm×11.32 mm×21.45 mm, the maximal von Mises stress in the lesion area reached 77.295 MPa, close to the yield strength of the mandible with a risk of pathological fracture. At this point, the remaining bone thickness of the buccal and lingual sides and the lower margin of the mandible in the lesion area was 1.52 mm, 0.76 mm and 1.04 mm, respectively.@*CONCLUSIONS@#Residual bone mass is an important factor to affect the risk of pathological fracture after curettage of cystic lesions. A thickness as low as 1 mm of the residual bone cortex in the cystic lesion area of the mandibular body can be used as the threshold for a clinical decision on one-stage windowing decompression combined with two- stage curettage.

ABSTRACT

OBJECTIVE@#To systematically evaluate the clinical efficacy of high-quality direct anterior approach (DAA) and other approaches for the treatment of elderly patients with femoral neck fracture.@*METHODS@#Literatures published in English or Chinese about the direct anterior approach and other approaches for hemiarthroplasty in femoral neck fracture were searched on Cochrane Library, PubMed, EMBASE, Web of science, Wanfang, CNKI databases from their establishment to May 2019. According to the inclusion and exclusion criteria, two researchers independently screened the literatures, and extracted the data. The quality of RCT were evaluated by Cochrane Risk of Bias Assessment Tool, and non-RCT were evaluated by the NOS scale. Meta-analysis was performed using the RevMan 5.3 software.@*RESULTS@#A total of 9 articles were included with 901 cases, in which 429 cases used DAA, and 472 used other approaches. DAA had a significantly lower dislocation rate compared to subgroup of posterior and posterolateral approach [=0.19, 95%CI (0.06, 0.61), =0.005]. No significant differences were found between DAA group and subgroup of direct lateral and anterolateral approach[=1.08, 95%CI(0.20, 5.76), =0.93]. Also there were no relevant differences between the DAA group and control in infection rate[=1.07, 95%CI(0.47, 2.43), =0.88], perioperative fracture rate[=0.95, 95%CI(0.36, 2.50), =0.92], re operation rate[=0.76, 95%CI(0.30, 1.89), =0.55], overall complication rate [=0.88, 95%CI (0.63, 1.22), =0.44], mortality [=1.33, 95%CI (0.84, 2.11), =0.23], operative time[MD=1.43, 95%CI(-5.85, 8.71), =0.70].@*CONCLUSION@#The current evidenceindicates that the DAA was associated with a significantly lower dislocation rate compared to posterior capsular approaches for hemiarthroplasty. There was no significant difference in dislocation rate with the lateral and anterolateral approach.

ABSTRACT

Scutellariae Radix(Huangqin) is a well-known traditional Chinese medicine(TCM) used for the treatment of clearing heat in clinical application. It is bitter-cold by using directly, but the bitter-cold property can be relieved after wine-frying. The study of taste changes before and after wine-frying of Scutellariae Radix is of great significance in identifying Scutellariae Radix and wine-processed Scutellariae Radix and clarifying the traditional theory of wine-processing. In this experiment, 10 batches of Scutellariae Radix and wine-processed Scutellariae Radix were prepared. The contents of 5 flavonoids were determined by high performance liquid chromatography(HPLC), and principal component analysis(PCA) was performed with 5 flavonoids as variables. As a result, the contents were different in different batches of Scutellariae Radix, but Scutellariae Radix and wine-processed Scutellariae Radix could not be distinguished. Five sensory attributes(sour, salty, fresh, sweet, and bitter) were evaluated by artificial tasting, and the response values of 7 sensors(AHS, AHS, PKS, CTS, NMS, CPS, ANS, SCS) representing the taste of pieces were detected by electronic tongue. The correlation between sensory evaluation and response values of the electronic tongue were analyzed, and the results showed that the sensory evaluation of sour, salty, fresh, sweet, bitter and AHS, CTS, NMS, ANS, SCS sensors had different degrees of correlation, indicating that the electronic tongue technology can be used as an alternative to artificial taste and can serve as a means for quantifying the taste, and it can be used to evaluate the taste of TCM pieces. The taste method was used to analyze the response values of the electronic tongue, and the results showed that the bitterness of wine-processed Scutellariae Radix decreased and the salty taste increased. PCA was used to analyze taste changes before and after wine-processed Scutellariae Radix, and the results showed that taste differences between 2 pieces were divided into 2 categories. PCA loading scattering plots showed that response of saltiness and bitterness were the major factors to affect overall taste in Scutellariae Radix and wine-processed Scutellariae Radix. Based on electronic tongue response values, the Fisher discriminant model for Scutellariae Radix and wine-processed Scutellariae Radix was established, which showed that it could effectively discriminate them with a recognition rate of 100%. The experimental results showed that the electronic tongue combined with multivariate statistical analysis can be used to evaluate taste of TCM, at the same time, it could provide a fast and simple method for identifying different processed products.

ABSTRACT

BACKGROUND@#Cardiac remodeling after acute myocardial infarction (AMI) is an important process. The present study aimed to assess the protective effects of astaxanthin (ASX) on cardiac remodeling after AMI.@*METHODS@#The study was conducted between April and September 2018. To create a rat AMI model, rats were anesthetized, and the left anterior descending coronary artery was ligated. The rats in the ASX group received 10 mg·kg·day ASX by gavage for 28 days. On the 1st day after AMI, but before ASX administration, six rats from each group were sacrificed to evaluate changes in the heart function and peripheral blood (PB) levels of inflammatory factors. On the 7th day after AMI, eight rats from each group were sacrificed to evaluate the PB levels of inflammatory factors and the M2 macrophage count using both immunofluorescence (IF) and flow cytometry (FC). The remaining rats were observed for 28 days. Cardiac function was examined using echocardiography. The inflammatory factors, namely, tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and IL-10, were assessed using enzyme-linked immunosorbent assay. The heart weight/body weight (BW), and lung weight (LW)/BW ratios were calculated, and myocardial fibrosis in the form of collagen volume fraction was measured using Masson trichrome staining. Hematoxylin and eosin (H&E) staining was used to determine the myocardial infarct size (MIS), and TdT-mediated dUTP nick-end labeling staining was used to analyze the myocardial apoptosis index. The levels of apoptosis-related protein, type I/III collagen, transforming growth factor β1 (TGF-β1), metalloproteinase 9 (MMP9), and caspase 3 were assessed by Western blotting. Unpaired t-test, one-way analysis of variance, and non-parametric Mann-Whitney test were used to analyze the data.@*RESULTS@#On day 1, cardiac function was worse in the ASX group than in the sham group (left ventricular end-systolic diameter [LVIDs]: 0.72 ± 0.08 vs. 0.22 ± 0.06 cm, t = -11.38; left ventricular end-diastolic diameter [LVIDd]: 0.89 ± 0.09 vs. 0.48 ± 0.05 cm, t = -9.42; end-systolic volume [ESV]: 0.80 [0.62, 0.94] vs. 0.04 [0.03, 0.05] mL, Z = -2.89; end-diastolic volume [EDV]: 1.39 [1.03, 1.49] vs. 0.28 [0.22, 0.32] mL, Z = -2.88; ejection fraction [EF]: 0.40 ± 0.04 vs. 0.86 ± 0.05, t = 10.00; left ventricular fractional shortening [FS] rate: 0.19 [0.18, 0.20] %FS vs. 0.51 [0.44, 0.58] %FS, Z = -2.88, all P < 0.01; n = 6). The levels of inflammatory factors significantly increased (TNF-α: 197.60 [133.89, 237.94] vs. 50.48 [47.21 57.10] pg/mL, Z = -2.88; IL-1β: 175.23 [160.74, 215.09] vs. 17.78 [16.83, 19.56] pg/mL, Z = -2.88; IL-10: 67.64 [58.90, 71.46] vs. 12.33 [11.64, 13.98] pg/mL, Z = -2.88, all P < 0.01; n = 6). On day 7, the levels of TNF-α and IL-1β were markedly lower in the ASX group than in the AMI group (TNF-α: 71.70 [68.60, 76.00] vs. 118.07 [106.92, 169.08] pg/mL, F = 42.64; IL-1β: 59.90 [50.83, 73.78] vs. 151.60 [108.4, 198.36] pg/mL, F = 44.35, all P < 0.01, n = 8). Conversely, IL-10 levels significantly increased (141.84 [118.98, 158.36] vs. 52.96 [42.68, 74.52] pg/mL, F = 126.67, P < 0.01, n = 8). The M2 macrophage count significantly increased (2891.42 ± 211.29 vs. 1583.38 ± 162.22, F = 274.35, P < 0.01 by immunofluorescence test; 0.96 ± 0.18 vs. 0.36 ± 0.05, F = 46.24, P < 0.05 by flowcytometry test). On day 28, cardiac function was better in the ASX group than in the AMI group (LVIDs: 0.50 [0.41, 0.56] vs. 0.64 [0.56, 0.74] cm, Z = -3.60; LVIDd: 0.70 [0.60, 0.76] vs. 0.80 [0.74 0.88] cm, Z = -2.96; ESV: 0.24 [0.18, 0.45] vs. 0.58 [0.44, 0.89] mL, Z = -3.62; EDV: 0.76 [0.44, 1.04] vs. 1.25 [0.82, 1.46] mL, Z = -2.54; EF: 0.60 ± 0.08 vs. 0.50 ± 0.12, F = 160.48; %FS: 0.29 [0.24, 0.31] vs. 0.20 [0.17, 0.21], Z = -4.43, all P < 0.01; n = 16). The MIS and LW/BW ratio were markedly lower in the ASX group than in the AMI group (myocardial infarct size: 32.50 ± 1.37 vs. 50.90 ± 1.73, t = 23.63, P < 0.01, n = 8; LW/BW: 1.81 ± 0.15 vs. 2.17 ± 0.37, t = 3.66, P = 0.01, n = 16). The CVF was significantly lower in the ASX group than in the AMI group: 12.88 ± 2.53 vs. 28.92 ± 3.31, t = 10.89, P < 0.01, n = 8. The expression of caspase 3, TGF-β1, MMP9, and type I/III collagen was lower in the ASX group than in the AMI group (caspase 3: 0.38 ± 0.06 vs. 0.66 ± 0.04, t = 8.28; TGF-β1: 0.37 ± 0.04 vs. 0.62 ± 0.07, t = 6.39; MMP9: 0.20 ± 0.06 vs. 0.40 ± 0.06, t = 4.62; type I collagen: 0.42 ± 0.09 vs. 0.74 ± 0.07, t = 5.73; type III collagen: 0.13 ± 0.02 vs. 0.74 ± 0.07, t = 4.32, all P < 0.01; n = 4).@*CONCLUSIONS@#ASX treatment after AMI may promote M2 macrophages and effectively attenuate cardiac remodeling by inhibiting inflammation and reducing myocardial fibrosis.

ABSTRACT

This study aimed to evaluate the clinical performance of p16/Ki-67 dual staining for triage high risk HPV (HR-HPV) infected women. Target objects were women who infected HR-HPV and received colposcopy examination between April and December of 2016 at the Second Affiliated Hospital of Zhengzhou University. Gynecologists collected the cervical exfoliated cells from eligible women for p16/Ki-67 dual staining, LBC testing and HPV DNA testing. Histology diagnosis were used as gold standard. Sensitivities, specificities, positive predictive values (PPVs), negative predictive values (NPVs) of p16/Ki-67 dual staining, LBC testing and HPV16/18 testing for triage of HR-HPV positive population were calculated and compared. A total of 295 HR-HPV infected women were selected, and the mean age was (44.29±11.48) years old. Positive rates of p16/Ki-67 dual staining, HPV16/18 testing and LBC testing were 70.17% (207), 56.95% (168) and 85.76% (253), respectively. When CIN2+as the endpoint, among the three triage methods, sensitivity of p16/Ki-67 dual staining was 90.00% (95: 85.06%-93.43%), higher than the value of HPV 16/18 testing, but lower than the value of LBC testing. Specificity, PPV and NPV of p16/Ki-67 dual staining were the highest [71.58% (95: 61.81%-79.67%), 86.96% (95:81.69%-90.88%) and 77.27% (95: 67.49%-84.78%)]. When detection for CIN3+, sensitivity of p16/Ki-67 dual staining was 92.90% (95: 87.74%-95.99%), lower than the value of LBC testing, but higher than the value of HPV16/18 testing. Specificity of p16/Ki-67 dual staining was 55.00% (95: 46.74%-63.00%), lower than the value of HPV16/18 testing, but higher than the value of LBC testing. PPV of p16/Ki-67 dual staining was 69.57% (95: 62.99%-75.43%), lower than the value of HPV 16/18 testing, but higher than the value of LBC testing. NPV of p16/Ki-67 dual staining was 87.50% (95: 78.99%-92.87%), higher than value of HPV 16/18 testing, but lower than the value of LBC testing. p16/Ki-67 dual staining has better clinical effects than HPV 16/18 testing and LBC testing for triage women with HR-HPV infection.

ABSTRACT

Objective:To investigate the effect of Salvia miltiorrhiza injection combined with human adipose derived stem cells (hADSC) on the survival rate of autologous fat granules implanted in nude mice.Methods:A total of 24 healthy 8 weeks old female nude mice weighing (23±3) g were randomly divided into four groups ( n=6): Group A was given fat granules 0.5 ml; Group B: fat granules 0.5 ml+ hADSC; Group C: Salvia miltiorrhiza 0.5 g/(kg·d) + fat granules 0.5 ml, and Group D: Salvia miltiorrhiza injection 0.5 g/(kg·d) + fat granules + enrichment. 3 nude mice were randomly selected from each group for 15 days after transplantation and stained with conventional HE. Immunohistochemical staining was performed to count the number of microvessels. On the 30th day after surgery, the remaining 3 nude mice in each group were sacrificed. The specimens were stained with HE and the volume of each specimen was measured. Results:Graft appearance was observed by naked eye: 15 days after the operation, all the specimens were formed completely. The new capillaries were shaped on the surface of the capsule. The boundaries of the capsule and the surrounding tissue were obvious. The activity was good, the hardness of the texture was medium, and the loose connective tissue was connected to the surrounding tissue. On the 30 day after operation, the volume of the graft was smaller than that at the beginning of transplantation, and fat liquefaction and necrosis were seen in some tissues. Blood vessel density values of immunohistochemical sections of fat transplantation in each group 15 days after surgery were compared pairwisely. The differences between the groups were statistically significant ( P<0.05). Lsd-t method was used for pairwise comparison of fat graft volume values of each group 30 days after surgery, and the difference between each group was statistically significant ( P<0.05). Conclusions:The combined use of Salvia miltiorrhiza injection and hADSCs can effectively promote the reconstruction of the early vascular system of the fat granule transplantation and improve the survival rate of fat particles more effectively than the individual use.

ABSTRACT

Objective:To reconstruct and repair forearm and foot injuries with soft tissue defect using medial sural artery perforator flap (MSAP), and to evaluate the curative effects.Method:From May, 2015 to September, 2017, 13 patients (9 males and 4 females) with soft tissue defect on forearm and foot underwent MSAP reconstruction operations. The age was ranged from 19 to 57 (mean 41) years. Six wounds located in forearms and 7 in foot. Ipsilater- al shank was used as donor for the repair of foot. The donor sites were directly sutured. The area of flaps was ranged from 3.0 cm×4.0 cm-7.0 cm×15.0 cm. All cases were followed-up for flap appearance, sensation and donor healing by visit of clinic and WeChat reviews.Results:All 13 flaps survived well without any vascular crisis nor necrosis. Postoperative superficial infections were found in 3 cases, and the wound healed gradually after daily dress changing and anti-infection treatment. Eleven patients were followed-up for 4 to 18 months (average 12 months). Two provincial patients lost to follow-up. No obvious disfunction was found from the donor shanks. The appearance and texture of flaps were in excellent condition and satisfactory. The sensation of 7 flaps was recovered to S 2-S 3. TPD was 6-9 mm. Conclusion:The free MSAP is rational therapeutic strategy for repairing the soft tissue defect of forearm and foot. It has advantages of long vascular pedicle, constant perforation and relatively thin subcutaneous fat.

ABSTRACT

The highlight of the 2020 EAU guideline updates on the systemic therapy for advanced and metastatic renal cell carcinoma is that monotherapy tyrosine kinase inhibitors, e.g. sunitinib, pazopanib, cabozantinib are not recommended as fist line treatment option for clear-cell metastatic renal cell carcinoma. Instead, immune checkpoint inhibitor combination therapy becomes the first choice for these patients. However, the targeted therapies can be offered as second-line therapy to patients refractory to pembrolizumab plus axitinib or nivolumab plus ipilimumab.

ABSTRACT

Objective:To report our experience in diagnosis and treatment of posterior atlantoaxial dislocation with odontoid retrolisthesis.Methods:A retrospective study was conducted of the 5 patients who had been treated from July 2012 to August 2018 at Department of Orthopaedics, General Hospital of Southern Theater Command for posterior atlantoaxial dislocation. They were 4 men and one woman, aged from 34 to 67 years (average, 47 years). All of them had a history of trauma. Of them, 4 were complicated with odontoid fracture and one with congenital free os odontoideum. Their posterior atlantoaxial dislocation ranged from 3 to 9 mm (average, 6 mm). By the American Spinal Injury Association (ASIA) grading system, their preoperative spinal injury was rated as grade B in one, as grade C in 3 cases and as grade D in one. All the 5 patients underwent skull traction at 10° flexion. Surgical trans-oralpharyngeal atlantoaxial reduction and internal fixation was performed for the one patient whose reduction had not been achieved by traction while posterior atlantoaxial screw-rod fixation or anterior odontoid screwing was conducted for the 4 patients whose reduction had been achieved by traction. The distance of posterior atlantoaxial dislocation was measured to evaluate their reduction and ASIA grade system was used to assess their spinal function after operation.Results:The postoperative distance of posterior atlantoaxial dislocation was 0 mm, showing a reduction rate of 100%. The 5 patients were followed up for 6 to 36 months (average, 15 months). By the ASIA grade system, the postoperative functional recovery of the spine was grade D in 4 cases and grade C in one. No implant loosening or breakage occurred.Conclusion:As a kind of high-energy hyperextension injury, posterior atlantoaxial dislocation is rare in clinic, but an appropriate treatment can be adopted to deal with its different clinical types to achieve good outcomes.

ABSTRACT

Objective:Intensive physicians have relatively insufficient knowledge and experience in treating patients with decompensated schistosomiasis cirrhosis (DSC) admitted in intensive care unit (ICU), but are relatively familiar with patients with decompensated alcoholic cirrhosis (DAC). For this purpose, the clinical characteristics and prognosis of these patients were compared and analyzed.Methods:A retrospective analysis was performed from January 2013 to May 2019 in our hospital and Quzhou People’s hospital. The demographic data, laboratory examination, liver function, Child-Pugh classification, complications of cirrhosis, ultrasonic imaging gastroscopy manifestations were recorded and analyzed. In addition, the treatments and prognosis were also compared.Results:A total of 30 patients (12 males and 18 females) with DSC (aged 57-88) and 31 patients with DAC (aged 41-75) were collected. Compared with patients with DAC, DSC patients were more likely to have coronary heart disease, lower proportion of hyponatremia and lower need of ventilator support. Although the incidences of jaundice and hepatic encephalopathy were significantly reduced ( P<0.05), but parameters of liver function and coagulation were no significant differences in both groups ( P>0.05). B-mode ultrasound of liver in patients with DSC displayed more proportion of patchy and diffuse echo changes and liver volume reduction ( P<0.05), whereas the manifestations of gastroscope in both groups were similar. No significant difference in main treatment measures like uses of somatostatin and three-chamber and two-capsule tube was observed. After treatment, the stop time of gastrointestinal bleeding was similar between groups of DAC and DSC [1.25 (0.5-4.125) days vs. 1.75 (1-2.375) days] ( P>0.05). In addition, the length of ICU stay in DAC group was similar to DSC group [(4.96±3.58) days vs. (3.82±1.99) days], so did the 28-day mortality [14.29% (2/14) vs. 18.18% (2/11)] (both P>0.05). Conclusions:In genenal, patients with decompensated schistosomiasis cirrhosis have the similar clinical characteristics, major biochemical indicators and accessory examination results like ultrasound and gastroscopic examinations to patients with decompensated alcoholic cirrhosis. After timely treatments, both of these patients could achieve a good prognosis.

ABSTRACT

The health literacy refers to the ability of individuals to acquire and understand basic health information and services and use them to make the right decisions to maintain and promote their health. Health literacy data focusing on cancer prevention and control was limited in China. In order to understand the health literacy and awareness of cancer risk factors and the cancer screening, early diagnosis and treatment in Chinese urban residents and compare the effect of different stages of the cancer intervention, the Cancer Screening Program in Urban China (CanSPUC) program, supported by the National Key Public Health Program, conducted a survey on the health literacy of the cancer prevention and treatment among urban residents in 16 provinces nationwide from 2015 to 2017. Four subgroups were designed in this survey, including (1) general population who have never participated in any cancer screening programs at a community-level; (2) individuals who have previously attended the CanSPUC program for cancer risk assessment or screening intervention; (3) cancer patients who were receiving treatment in local hospitals; (4) a special group from employees of government and public institutions (non-health system), state-owned enterprises and private enterprises (to have better understand on the impact of socioeconomic factors). The self-designed questionnaire covered six parts, including basic information, consciousness of common risk factors to cancer, awareness of early detection, awareness of early diagnosis, awareness of early treatment, and the needs and approaches for knowledge of cancer prevention and treatment. A total of 32 257 individuals were included in the final analyses. This paper landscaped the overall design of the survey, including participants, domains of the instrument, quality control, basic characteristics of the included individuals. These descriptions are applicable to each individual report of the current special issue of "Health Literacy of Cancer Control in Urban China" and future reports, in which more detailed results are and will be reported. The findings of this survey could provide some useful implications for similar researches in the future.

ABSTRACT

Objective@#To investigate the demand and access to the cancer prevention and treatment knowledge and related factors among urban residents in China from 2015 to 2017.@*Methods@#A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. The self-designed questionnaire was used to collect the information of general demographic characteristics, the demand and access to cancer prevention and treatment knowledge, and the influencing factors of the attitude. The Chi-square test was used to analyze the difference of the demand of the cancer prevention knowledge among different groups and the corresponding factors of the cancer prevention and treatment knowledge were analyzed by using the logistic regression model.@*Results@#The proportion of residents who need the cancer prevention and treatment knowledge was 79.5%. The demand rate of the inducement, symptom and diagnosis methods of cancer in the occupational population was highest, about 66.8%, 71.0% and 20.8%, respectively. The demand rate of treatment methods and cost in current cancer patients was the highest, about the 45.9% and 21.9%, respectively. The top three sources to acquire the cancer prevention and treatment knowledge were "broadcast or television" (69.5%), "books, newspapers, posters or brochures" (44.7%) and "family and friends" (33.8%). The multivariate analysis showed that compared with public institution personnel/civil servants, unmarried/cohabiting/divorced/widowed and others, annual household income less than 20 000 CNY, from the eastern region, people without cancer diagnosis and people with self-assessment of cancer risk, the demand rate of cancer prevention and treatment knowledge was higher in enterprise personnel/workers, married, annual household income between 60 000 CNY and 150 000 CNY, from the central region, people with cancer and people with unclear cancer risk (all P values <0.05).@*Conclusion@#There was a high demand for the cancer prevention and treatment knowledge among urban residents in China from 2015 to 2017. The main access to the knowledge is from the radio or television. The occupation, marital status, annual household income, residential region, health status and risk of disease were the main factors of the demand of the cancer prevention and treatment knowledge.

ABSTRACT

Objective@#To understand the health literacy of the cancer prevention and treatment among urban residents of China, and explore the related factors.@*Methods@#A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China (CanSPUC) from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. The health literacy of the cancer prevention, early discovery, early diagnosis, early treatment and the demands of cancer prevention and treatment knowledge was analyzed. The level of health literacy among different groups were calculated and compared. The binary logistic regression model was used to analyze the influencing factors of the health literacy of the cancer prevention and treatment.@*Results@#The level of health literacy of the cancer prevention and treatment was 56.97% among all study population; in each group it was 55.01% for community residents, 59.08% for cancer risk assessment/screening population, 61.99% for cancer patients and 57.31% for occupational population, respectively (P<0.001). The level of health literacy of the cancer prevention and treatment of residents aged 50 to 69 years old, other occupational groups, unmarried, the central and western region residents and the group with unclear self-assessment of cancer risk was significantly lower than that of residents younger than 40 years old, personnel of public institutions/civil servants, married, the eastern region residents and the group whose self-assessment without cancer risk (P<0.05) . The level of health literacy of cancer prevention and treatment of females, people who went to high school or over, cancer risk assessment/screening population, cancer patients and occupational population was significantly higher than that of males, people who had an education level of primary school or below and community residents (P<0.05) .@*Conclusion@#The health literacy of the cancer prevention and treatment of urban residents in China was relatively high, but there was still room for improvement. Gender, age, educational level, occupation, region, marital status, self-assessment of cancer risk, and type of respondents were the key influencing factors of the health literacy of the cancer prevention and treatment. Male, 50-69 years old, lower educational level, central and western regions, unclear cancer risk self-assessment, and without specific environmental exposure to cancer prevention and treatment knowledge or related risk factors were the characteristics of the key intervention group of the health literacy of the cancer prevention and treatment.
