ABSTRACT

Objective:To estimate in-hospital mortality after knee replacement (KR) and to assess its trend and risk factors in China.Methods:We included patients undergoing KR in the Hospital Quality Monitoring System in China (2013-2019) to estimate in-hospital mortality after KR and assessed relation of patient's and hospital's characteristics (year of surgery, age, gender, marital status, primary indication, Charlson comorbidity index, geographic location, hospital type, hospital volume of KR, and surgery type) to in-hospital mortality using multivariable Poisson regression.Results:The annual amount of KR has increased from 20 307 in 2013 to 35 757 in 2019, and has maintained an upward trend for 7 years. The mean age of patients having KR increased from 64.9 years in 2013 to 66.6 years in 2019. Of the total 218 923 KRs, 63 deaths (0.29‰) occurred within 30 days before discharging. Older age was associated with higher in-hospital mortality ( P for trend <0.001). Male gender had higher incidence of in-hospital mortality compared with female [relative risk (RR), 2.5; 95% CI: 1.5, 4.1]. Single marital status was associated with higher, albeit non-statistically significant, in-hospital mortality than married patients (RR, 2.1; 95% CI: 0.9, 4.6). Higher Charlson comorbidity index was associated with increased risk of in-hospital mortality ( P for trend <0.001). Risk of in-hospital mortality decreased with more hospital-year knee replacement surgeries ( P for trend <0.001). In-hospital mortality varied by geographic regions, with the lowest mortality in East region (0.16‰), followed by South-West (0.31‰), South-Central (0.31‰), North region (0.33‰), North-West (0.54‰) and North-East (0.59‰). Conclusion:In-hospital mortality after KR in China was relatively low. Older age, male gender, higher Charlson comorbidity index and lower hospital-year knee replacement surgeries were risk factors for in-hospital mortality. The mortality varied greatly according to the geographic location of hospital.

ABSTRACT

Intestinal mucus barrier is a gel network composed of mucin, water and antimicrobial peptides. It is the first line defense of host against intestinal pathogens, and is also important for the survival and proliferation of symbiotic bacteria. Mucins are mainly synthesized and secreted by goblet cells of intestine, forming different structures in different intestinal segments. Nowadays more and more studies have shown that the mucus barrier is not only closely related to intestinal infection, inflammatory bowel disease, intestinal tumor and other intestinal diseases, but also involved in the occurrence and development of some extraintestinal diseases, such as acute pancreatitis, non-alcoholic fatty liver disease, which may become a new target for the treatment of various related diseases in the future.

ABSTRACT

Objective:To analyze the clinical characteristics of gastrointestinal symptoms and liver function injury in patients with coronavirus disease 2019 (COVID-19).Methods:From January 23, 2020 to February 29, 2020, the medical records of 251 patients with COVID-19 admitted to the West Campus of the Union Hospital, Tongji Medical College of Huazhong University of Science and Technology, were collected. The proportion of the patients with gastrointestinal symptoms including anorexia, nausea and vomiting, diarrhea and abdominal pain were analyzed respectively. The patients were divided into common type (76 cases), severe type (65 cases) and critical type (110 cases). The incidence of liver function injury and the changes of liver function parameters such as total bilirubin (TBil), direct bilirubin (DBil), alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), γ-glutamyl transpeptidase (GGT), lactate dehydrogenase (LDH), albumin and globulin of the patients with different clinical types and with or without gastrointestinal symptoms were analyzed. Mann-Whitney U test, Chi square test and Fisher′s exact test were used for statistical analysis. Results:The main gastrointestinal symptoms of patients with COVID-19 were anorexia (33.9%, 85/251), diarrhea (12.0%, 30/251), nausea and vomiting (7.6%, 19/251) and abdominal pain (1.2%, 3/251). 143 patients (57.0%) had liver function injury, the rate of liver function injury in critical type patients was 75.5% (83/110), which was higher than that of common type patients (40.8%, 31/76) and severe type patients (44.6%, 29/65), and the differences were statistically significant ( χ2=22.765 and 16.865, both P<0.01). There was no significant difference in the proportion of patients with liver function injury between common type and severe type patients ( P>0.05). There was no statistically significant difference in the proportion of liver function injury between patients with gastrointestinal symptoms and those without gastrointestinal symptoms (57.8%(67/116) vs. 56.3%(76/135), P>0.05). The median values of TBil, DBil, ALT, AST, ALP, GGT, LDH and globulin level of critical type patients were 13.5 μmol/L, 4.9 μmol/L, 44.5 U/L, 50.0 U/L, 64.0 U/L, 41.0 U/L, 527.0 U/L and 33.6 g/L respectively. The proportions of critical type patients with TBil level >34.2 μmol/L, DBil level>13.6 μmol/L, ALT level>80 U/L and AST level>80 U/L were 7.3% (8/110), 7.3% (8/110), 17.3% (19/110) and 17.3% (19/110), respectively. These results were all higher than those of common type patients (9.5 μmol/L, 2.9 μmol/L, 28.5 U/L, 28.5 U/L, 54.0 U/L, 25.5 U/L, 225.5 U/L, 30.1 g/L, 0, 0, 6.6% (5/76) and 2.6% (2/76) ) and severe type patients (10.4 μmol/L, 3.4 μmol/L, 30.0 U/L, 31.0 U/L, 49.0 U/L, 25.0 U/L, 284.0 U/L, 30.7 g/L, 0, 0, 6.2% (4/65) and 1.5% (1/65)), and the differences were statistically significant ( Z=-4.264, -5.507, -4.000, -6.558, -3.112, -4.333, -4.858, -3.873, Fisher′s exact test, Fisher′s exact test, χ2=4.574, 9.620; Z=-3.060, -3.850, -3.923, -5.005, -9.495, -7.651, -3.853, -2.725, Fisher′s exact test, Fisher′s exact test, χ2=4.425, 10.169; all P<0.01). The median values of pre-albumin level, albumin level and the albumin to globulin ratio of critical type patients were 85.3 g/L, 28.2 g/L and 0.8, which were all lower than those of common type patients (157.3 g/L, 32.3 g/L and 1.1, respectively) and severe type patients (133.6 g/L, 31.6 g/L and 1.1, respectively), and the differences were statistically significant ( Z=-6.631, -3.647, -4.924, -4.503, -5.283 and -3.903, all P<0.01). The median albumin level of patients with diarrhea was lower than that of patients without diarrhea (28.2 g/L vs. 30.5 g/L), the proportion of diarrhea patients whose TBil level >20.0 to 34.2 μmol/L was higher than that of patients without diarrhea (70.0%, 21/30 vs. 10.9%, 24/221), and the differences were statistically significant ( Z=-2.182, χ2 =62.788; both P<0.05). Conclusions:Anorexia is the most common digestive symptom in COVID-19 patients, and the incidences of abdominal pain is low. The incidence of liver function injury of critical type patients is high. There is no significant correlation between gastrointestinal symptoms and liver function injury, and patients with diarrhea have lower albumin levels.

ABSTRACT

BACKGROUND:Progressive fracture of the cartilage is considered the characteristic lesion in later osteoarthritis, the expression of osteoarthritis-related factors such as hyaluronic acid, osteopontin and CD44 in osteoarthritic cartilage is increased. OBJECTIVE:To investigate the effect of hyaluronic acid on the expression of osteopontin mRNA and CD44 mRNA of chondrocytes in the in vitro cultured chondrocytes of patients with knee osteoarthritis. METHODThe cartilage samples obtained from osteoarthritic patients were cultured and purified into acquire chondrocytes in vitro, and the cells were divided into three groupblank control group, hyaluronic acid (100 mg/mL) group and hyaluronidase (200 mg/mL) group. After 48 hours of cellculture, real-time quantitative polymerase chain reaction assay was used to detect the expression of CD44 mRNA and osteopontin mRNA. The difference of the expression levels before and after the intervention of hyaluronic acid was compared and analyzed using SPSS 17.0 software. RESULTS AND CONCLUSION:Compared with the blank control group, hyaluronic acid (100 mg/mL) upregulated osteopontin mRNA expression in the chondrocytes, hyaluronidase (200 mg/mL) also reduced osteopontin mRNA expression in the chondrocytes. The CD44 mRNA expression in the chondrocytes of hyaluronic acid (100 mg/mL) group and hyaluronidase (200 mg/mL) group was lower than that in the blank control group. Hyaluronic acid can upregulate the expression of the osteopontin mRNA expression in the osteoarthritic chondrocytes;the biphasic effects of hyaluronic acid on CD44 mRNA expression in osteoarthritic chondrocytes might be associated with the molecule weight of hyaluronic acid.

ABSTRACT

Objective To explore the feasibility and value of MSCT for the evaluation of hypophysoma before and after endonasal transphenoidal microsurgery.Methods 82 patients with hypophysoma intended to be treated by endonasal transphenoidal microsur-gery,were examined by 64-slice head CT angiography (CTA).All the images were transmitted to workstation and reconstructed by MIP、VR and MPR.The hypophysoma were typed according to the relationship between hypophysoma and its surrounding vessels. The shortest and longest diameter between internal carotid arteries of two sides,tumor length and width,the diameter between ex-ternal naris and the rear wall of sphenoid top and the length from external naris to the rear wall of tumor top were measured in VR images.Sphenoid division was observed in coronal plane image.Major vascular injury,bleeding,and residual tumor situation were observed on postoperative CT review.The surgery effect was evaluated by three associate professorwith SPSS 13.0.Results 39 ca-ses were type-A,30 were type-B,13 were type-C,tumor length ranged from 1.7 cm to 3.9 cm,width ranged from 1.3 cm to 2.5 cm,the diameter between external naris and the rear wall of sphenoid top and the length between external naris and the rear wall of tumor top were 6.9 cm~7.6 cm and 9 cm~12.2 cm.There are 1 5 cases of sphenoid without division,34 cases with one divi-sion,26 cases with two division and at least three division in 7 cases.The surgery effect was better in those which tumor size was relatively smaller compared to the diameter of the internal carotid artery.The evaluation of endoscopic endonasal transsphenoidal surgery with three types of pituitary adenomas had a significant difference (P <0.05).Conclusion MSCT can preferably reflect the spatial location relationship between pituitary adenimas and its surrounding structure,and it is effective evaluation methods for pre-operative and postoperative evaluation of transnasal microsurgical resection.

ABSTRACT

BACKGROUND:Pain after arthroscopic treatment can not only affect the patient’s life quality, and is not conducive to the early reasonable exercise and functional recovery of the patients after treatment. Up to 2012, there are 18 randomized placebo-control ed trials on intra-articular injection of bupivacaine for analgesia after arthroscopic surgery, but the results are different. OBJECTIVE:To examine the efficacy and safety of intra-articular injection of bupivacaine in the management of pain after arthroscopic surgery through randomized placebo-control ed trials. METHODS:The MEDLINE database, Cochrane Central Register and Google Scholar database were retrieved for the randomized control ed trials on intra-articular injection of bupivacaine in the management of pain after arthroscopic surgery up to April 2012. The key words were“bupivacaine, intra-articular, arthroscopic, postoperative pain, placebo”. RESULTS AND CONCLUSION:Eighteen studies (n=934) were included (461 cases in bupivacaine group and 473 cases in the placebo control group). The Meta-analysis results showed the visual analog scale score of the bupivacaine group was lower than that of the placebo control group (weighted mean difference:-1.39, 95%confidence interval:-2.17 to-0.61, Pmean difference:157.72, 95%confidence interval:16.43 to 299.01, P<0.000 01). There was no significant difference in the incidence of side effect between two groups (relative risk:0.64, 95%confidence interval:0.29 to 1.44, P=0.48). On the basis of the currently available literature, the intra-articular of bupivacaine after arthroscopic surgery can significantly relieve pain without increasing the adverse reactions when compared with the placebo control group.
