ABSTRACT

Objective To evaluate the safety and efficacy of CT-guided percutaneous transhepatic gallbladder drainage(PTGBD)in treatment of high-risk acute cholecystitis(AC)patients.Methods CT-guided PTGBD was performed in 29 patients with high-risk AC.The therapeutic results were evaluated by comparing the preoperation and postoperation clinical manifestations and laboratory results.Results The implantation of PTGBD catheter was successfully accomplished with single procedure in all patients.Complica-tions occurred in 2 cases,including abdominal pain in 1 case and a small amount of gallbladder bleeding in 1 case,and the incidence of complications was 6.9%.Compared with preoperation,the pain number rating scale(NRS)score,temperature(T),white blood cell count(WBC),C-reactive protein(CRP),total bilirubin(TBIL),alanine aminotransferase(ALT)and aspartate aminotransferase(AST)were significantly decreased 3 days after PTGBD(P<0.001).Except for 1 case of choledocholithiasis with continuous abdominal pain after PTGBD,the postoperation symptoms of the other patients were significantly relieved.Followed up for 3 months,2 cases of calculous AC recurred after PTGBD,and the recurrence rate of cholecystitis was 25.0%.Conclusion For high-risk AC,the CT-guided PTGBD is a safe and effective treatment method,and it can remarkably relieve the clinical symptoms.Patients with calculous AC have higher risk of recurrence and might benefit from definitive cholecystectomy.

ABSTRACT

Objective:To investigate the kinetic metrics of 68Ga-fibroblast activation protein inhibitor (FAPI)-04 in pancreatic cancers and normal organs by using total-body PET dynamic imaging. Methods:From December 2020 to December 2021, 68Ga-FAPI-04 total-body PET/CT dynamic imaging were performed on 6 pancreatic cancer patients (3 males, 3 females, median age 55.5 years) in Ren Ji Hospital, School of Medicine, Shanghai Jiao Tong University. Images were respectively analyzed. Manual delineations of volume of interests (VOIs) on multiple normal organs and pathological lesions were performed and time-to-activity curves (TACs) were generated. A reversible two-tissue compartment model (2TCM) was fitted for each tissue TAC. Rate constants including K1, k2, k3 and k4, and the total volume of distribution ( Vt) were obtained and compared by tissue types. Wilcoxon rank sum test and Spearman correlation analysis were used for data analysis. Results:Kinetic metrics varied significantly among normal organs and pancreatic cancer lesions ( z values: 2.00-1 240.00, all P<0.05). The highest K1 among lesions was observed in primary tumor (0.30 min -1), which was observed in the spleen (1.42 min -1) among normal organs. The highest k2 among lesions was observed in peritoneal metastases (0.24 min -1), which was observed in the spleen (2.59 min -1) among normal organs. Primary tumor showed the highest k3 of 0.17 min -1 among lesions, and the pancreas had the highest k3 of 0.16 min -1 among normal organs. Primary tumor had the highest k4 of 0.03 min -1 among lesions, and the heart, lungs, parotid glands had high k4(0.06 min -1) among normal organs. Vt were higher in pathological lesions compared to normal organs, with the highest in primary tumor (13.78 ml/cm 3). There were correlations between Vt in lesions and SUV mean( rs=0.86, P<0.001) or SUV max ( rs=0.77, P<0.001). Conclusion:The rate constants including K1, k2, k3 and k4, and Vt of 68Ga-FAPI-04 vary among normal organs and lesions.

ABSTRACT

Objective:To investigate a classification on age of diagnosis and its clinical characteristics in hospitalized elderly patients with first diagnosed Crohn's disease.Methods:This was retrospective case-control study.A total of 181 newly diagnosed CD patients were admitted to Huadong Hospital from January 2005 to December 2019.According to Montreal CD classification criteria based on the age at the time of diagnosis(sub-grouping A3 into A3 and A4 in this paper), 181 CD patients were classified into four groups: the A1 group(≤16 years, n=4), A2 group(17-40 years, n=60)and A3 group(41-59 years, n=63)(above three as control groups), and the A4 group[≥60 years, with elder-onset Crhon's disease(EOCD), n=54]as a study group.Results:A total of 181 first diagnosed CD patients who met the diagnostic criteria were included in this study.During the investigation period, the total incidence rate of CD was 37.90/100, 000, and the total prevalence rate of CD was 142.79/100, 000.Among the 181 first diagnosed CD patients, there were 4 patients(2.2%)with age of diagnosis of ≤16 years(group A1), 60 patients(33.2%)with age of diagnosis of 16-40 years(A2), 63 patients(34.8%)with age of diagnosis of 41-59 years(A3)and 54 patients(29.8%)with age of diagnosis of ≥=60 years(A4). Of these first diagnosed CD patients, male were dominant in A2 group(51 males / 9 females), while the ratio of males and females tended to be the same(32 males /31 females)in A3 group, and the proportion of female patients was greater than that of male patients in A4 group(25 males /29 females)( P<0.0001). The main CD lesion was ileocolic type in the EOCD group, accounting for 57.4%( P=0.0077). The incidence rate of ileus type CD was 42.6%( P=0.1942). Among the 163 CD patients who underwent colonoscopy, under Simple Endoscopic Score for CD(SES-CD)evaluation, the proportion of SES-CD severity type in EOCD group was as high as 82.2%, which was higher than that in the A3 group(51.7%, P=0.0187). All CD patients underwent pathological examination.There were 173 cases(95.6%)with focal lymphocytic infiltration, 120 cases(66.3%)with inflammatory infiltration on the crypt epithelial and 82 cases(45.3%)with non-caseous granuloma tissue.In the EOCD group, non-caseous granuloma accounted for 61.1%, which was higher than that in the A3 and A2 groups( P=0.0318). In the EOCD group, the non-complication rate was 1.89%, and the incidence rates of 3, 4 and ≥5 complications were 14.8%, 22.2% and 24.1%, respectively( P<0.0001, P=0.0280, 0.0141 and 0.0013). The sulphasalazine(SASP)alone was the main treatment method, accounting for 42.6%( P=0.0038), and the surgery accounted for 24.1%( P=0.9598). Conclusions:The incidence and trend of EOCD are basically consistent with those of adult-onset CD and showed an rising volatility.Incidence rate of EOCD is higher in females than in males.EOCD lesions of visual observation under endoscope are serious.The detection rate of non-caseous granulomas and related scars is high under microscope.EOCD patients have many complications, and SASP alone is the main treatment method.

ABSTRACT

Objective:To investigate the effect and mechanism of Acyl-CoA: lysocardiolipin acyltransferase 1 (ALCAT1) on hepatocyte steatosis and oxidative stress in fatty liver cell model.Methods:A fatty liver cell model was established and induced by free fatty acids (FFA). The expression of ALCAT1 in fatty liver cell model was detected by quantitative real-time polymerase chain reaction (qRT-PCR) and Western blotting. The empty siRNA plasmid and ALCAT1 siRNA plasmid were constructed. For the fatty liver cell model group, human normal hepatocytes (L-02 cells) were transfected with empty siRNA plasmid for 24 hours, and then cultured with FFA for 24 hours. For the ALCAT1 interfering group, L-02 cells were transfected with ALCAT1 siRNA plasmid for 24 hours, and then cultured with FFA for 24 hours. And L-02 cells cultured in common medium were used as as blank control group. Lipid droplet deposition and mitochondrial morphology were observed under transmission electron microscopy. The expression levels of autophagy-associated proteins (microtubule-associated protein 1 light chain 3 (LC3)-Ⅱ and Beclin1) and key proteins of autophagy signal pathway (mammalian target of rapamycin (mTOR) and serine/threonine kinase (AKT)) were measured by Western blotting. The expression levels of oxidative stress products (malondialdehyde, 4-hydroxynonenal (4-HNE) and reactive oxygen species (ROS)) and inflammatory factors (interleukin-6(IL-6) and tumor necrosis factor (TNF)-α) were detected by enzyme-linked immunosorbent assay (ELISA) kits. Independent sample t test was used for statistical analysis. Results:The mRNA and protein expression levels of ALCAT1 of the fatty liver cell model group were both higher than that of negative control group (9.26±0.83 vs. 1.02±0.12, 0.35±0.02 vs. 0.17±0.01), and the differences were statistically significant ( t=9.82 and 6.83, both P<0.05). The results of electron microscopy indicated that the deposition of lipid droplets of the fatty liver cell model group and ALCAT1 interfering group were both higher than that of blank control group (17.67±3.52 and 7.67±0.33 vs. 4.33±0.33), the quantity of lipid droplets deposition of ALCAT1 interfering group was lower than that of fatty liver cell model group (7.67±0.33 vs. 17.67±3.52), and the differences were statistically significant ( t=3.76, 7.07 and 2.82, all P<0.05). The degree of mitochondria swelling of fatty liver cell model group was higher than that of blank control group and the degree of mitochondria swelling of ALCAT1 interfering group was lower than that of fatty liver cell model group.

However there was no significant difference in the expression level of Beclin1 between fatty live cell model group and blank control group (0.93±0.05 vs. 0.98±0.05, P>0.05). The expression levels of LC3-Ⅱ and Beclin1 of the ALCAT1 interfering group were both higher than those of the fatty liver cell model group and blank control group (0.95±0.04 vs. 0.42±0.01 and 0.28±0.02, 2.07±0.06 vs. 0.93±0.05 and 0.98±0.05), and the differences were statistically significant ( t=13.30, 15.63, 14.05 and 13.02, all P<0.05). The expression levels of mTOR of the fatty liver cell model group and ALCAT1 interfering group were both lower than that of the blank control group (1.44±0.02 and 0.74±0.01 vs. 1.93±0.10), the expression level of mTOR of the ALCAT1 interfering group was lower than that of the fatty liver cell model group (0.74±0.01 vs. 1.44±0.02), and the differences were statistically significant ( t=4.83, 12.04 and 32.14, all P<0.05). The expression levels of phosphorylated AKT of the fatty liver cell model group and ALCAT1 interfering group were both lower than that of the blank control group (0.14±0.01 and 0.07±0.01 vs. 0.28±0.01), while the expression level of phosphorylated AKT of the ALCAT1 interfering group was lower than that of the fatty liver cell model group (0.07±0.01 vs. 0.14±0.01), and the differences were statistically significant ( t=8.59, 14.10 and 5.96, all P<0.05). The results of ELISA indicated that the expression levels of ROS, malondialdehyde, 4-HNE, IL-6 and TNF-α of the fatty liver cell model group and the ALCAT1 interfering group were all higher than those of the blank control group ((11.44±0.30) and (5.84±0.36) g/L vs. (1.72±0.38) g/L; (19.94±2.47) and (11.95±1.55) μmol/L vs. (1.47±0.18) μmol/L; (5.00±0.43) and (2.99±0.37) ng/L vs. (1.46±0.23) ng/L; (203.40±5.16) and (92.07±11.98) ng/L vs. (23.32±3.33) ng/L; (123.70±8.38) and (67.42±4.88) ng/L vs. (47.18±4.57) ng/L), and the differences were all statistically significant ( t=19.86, 7.86, 7.45, 6.74, 7.22, 3.49, 29.34, 5.53, 8.02 and 3.03, all P<0.05). While the expression levels of ROS, 4-HNE, IL-6 and TNF-α of the ALCAT1 interfering group were all lower than those of the fatty liver cell model group ((5.84±0.36) g/L vs. (11.44±0.30) g/L, (2.99±0.37) ng/L vs. (5.00±0.43) ng/L, (92.07±11.98) ng/L vs. (203.40±5.16) ng/L and (67.42±4.88) ng/L vs. (123.70±8.38) ng/L), and all the differences were statistically significant ( t=11.99, 3.51, 8.54 and 5.81, all P<0.05). There was no statistically significant difference in the expression of malondialdehyde between ALCAT1 interfering group and fatty liver cell model group ((11.95±1.55) μmol/L vs. (19.94±2.47) μmol/L, P>0.05). Conclusions:The expression of ALCAT1 is up-regulated in fatty liver cell model. Knockdown of ALCAT1 can inhibit the expression of mTOR pathway proteins, activate autophagy, alleviate hepatocyte steatosis, oxidative stress and inflammatory response.

ABSTRACT

The Clinical therapeutic effect and safety of celecoxib in treating knee osteoarthritis were observed. 180 patients who have been confirmed with knee osteoarthritis in our hospital were selected as research objects. They were randomly divided into research group and control group, each containing 90 patients. The control group was given with diclofenac sodium therapy, while the research group was subjected to celecoxib therapy. The total therapeutic response rates between the two groups were observed and compared. The total therapeutic response rate of research groups was relatively higher, P<0.05. There was no significant difference in pain score, erythrocyte sedimentation rate [ESR], quality of life score [QLS] between two groups before treatment, P<0.05. However, these indexes of research group were superior then the control group after treatment, P<0.05. In addition, the rate of adverse reaction of research group was also lower than that of control group, P<0.05. Using celecoxib to treat knee osteoarthritis can significantly improve the total therapeutic rate and reduce the rate of adverse effect

ABSTRACT

Objective The purpose of this study was to study the correlation between dental fluorosis, saliva and plaque fluoride levels and urinary fluoride values in adolescents dental fluorosis. Methods A middle school was chosen as a survey point in the study. Two hundred adolescents were examined the degree of dental fluorosis by Dean's method. These adolescents were divided into four groups according to the severity of fluorosis (n = 52, 40, 28 and 80). Fluoride ion specific electrode was used to measure the fluoride levels in dental plaque, saliva, urinary and drinking water. The differences were analyzed b y ANOVA. Correlation of the fluoride levels between dental plaque, saliva, urine and the degree of dental fluorosis were analyzed by the method of multiple linear regression. Results The average fluoride content of drinking water was (2.20 ± 0.40) mg/L. Compared with controls, the fluoride concentrations in dental plaque, saliva and urine were higher in light, medium and severe dental fluorosis groups [(1.55 ± 0.88), (1.94 ± 0.77), (2.74 ± 0.83) than (0.32 ± 0.20) mg/L; (4.44 ± 1.62), (8.09 ± 0.93), (10.72 ± 0.99) than (0.02 ± 0.01) mg/L;(31.77 ± 6.09), (57.98 ± 1.83), (65.98 ± 2.78) than (13.06 ± 2.11) μg/g, all P<0.05]. Urinary fluoride was correlated with fluoride in saliva and dental plaque (r=0.245, 0.440, all P<0.05). Saliva fluoride was correlated with fluoride in dental plaque (r=0.849, P<0.01). The degree of dental fluorosis was correlated with fluoride in urine and saliva (r = 0.497, 0.896, 0.924, all P< 0.01). The multiple linear regression equation between fluoride in urine and the degree of dent al fluorosis, fluoride in dental plaque and saliva was as follow: y = 1.357 + 1.618x1 + 0.001x2 - 0.331x3 ± 0.69. Conclusions The metabolism of fluoride in body is related with oral fluoride repository in adolescents dental fluorosis. Fluoride in urine is influenced by plaque fluoride level, saliva fluoride concentration and the degree of dental fluorosis.

ABSTRACT

Pulmonary edema frequently occurs after severe burn. It not only impairs pulmonary function directly, but also can induce or exacerbate other pulmonary complications such as lung infection, acute lung injury ( ALI), and ARDS. Extravascular lung water (EVLW) is closely related to the pulmonary edema. Dynamical monitor of EVLW has been used to predict and quantify the degree of pulmonary edema clinically. This review focuses on the recent progresses at home and abroad on the formation mechanism, monitoring approach, and prevention and treatment of EVLW after severe burn injury.

ABSTRACT

Objective To explore the effects of using proton pump inhibitors (PPIs) on the outcomes of hip fracture.Methods Searches were conducted through Medline,Embase,Cochrane Library and Chinese Biomedical Literature Database to identify the studies of the association between PPIs exposure and hip fracture.Quality of studies was assessed using the Newcastle-Ottawa Quality Assessment Scale.Pooled odds ratios (ORs) and 95% confidence interval (CIs) were calculated for the risk of hip fracture associated with current exposure of PPIs.And several subgroups were analyzed by dosing duration,dose,osteoporosis and corticosteroid usage to explore potential study heterogeneities.All statistical analyses were performed with STATA software.Results Among 11 publications included for final analysis,there were a total of 1 107 577 subjects with an average age of over 60 years.A positive relationship existed between PPIs exposure and hip fracture with an OR of 1.46 (95% CI:1.26-1.70,P =0.000) as compared with nonPPI-users,especially those on concurrent corticosteroid and PPIs.A significantly increased risk of hip fracture was found in the group of a short-term duration for under 1 year (OR =1.18,95% CI:1.01-1.38,P =0.041),medium-term for 1-3 years (OR =1.23,95% CI:1.01-1.49,P =0.038) and longer duration for over 6 years (OR =1.38,95% CI:1.27-1.50,P =0.000).Furthermore,concurrent use of PPIs was not associated with an increased risk of hip fracture in a definite dose-response manner.As compared with non-PPI-users,no significantly increased risk of hip fracture was found in PPI-users with osteoporosis (P > 0.05).Publication bias was not present.Conclusions Use of PPIs may be somewhat associated with an increased risk of hip fracture.Considering potential adverse effects,clinicians should prescribe cautiously PPIs for high-risk patients,especially elders.
