ABSTRACT

OBJECTIVE@#To investigate the effectiveness of modified Caprini risk assessment model(Caprini MRAM) in predicting the risk of deep venous thrombosis (DVT) after total knee arthroplasty (TKA).@*METHODS@#A case-control study was used to collect 43 patients with DVT after TKA in lower limb department of Sichuan Orthopedic Hospital from January 2016 to November 2020 in the positive group, and 172 patients without DVT after TKA in the same period according to the 1∶4 ratio between positive and control group were selected in the control group. Caprini MRAM was used to score and grade the risk of DVT. The clinical data, score and risk classification of the two groups were compared. The relationship between the risk of DVT in the patients after TKA and the risk factors in the risk ckassification and assessment of Caprini MRAM was analyzed by multivariate logistic regression model.@*RESULTS@#The average score of caprini in DVT group was significantly higher than that in control group[(8.11±2.91) vs(4.07±2.12), P<0.001];DVT group was mainly at medium and high risk group(66.67%), while the control group was mainly at low risk (77.33%). There was a significant difference between the two groups in risk classification composition (P<0.001). BMI≥30 kg/m2, lower extremity edema (<1 month), severe pulmonary disease (<1 month), acute myocardial infarction (<1 month), bed rest (> 2 h), history of superficial or deep vein or pulmonary embolism and family history of thrombosis were the main risk factors for DVT in patients after TKA(all P<0.05). Preoperative D-dimer elevation (OR=4.380), BMI≥30 kg/m2(OR=2.518), lower extremity edema(<1 month)(OR=7.652), acute myocardial infarction (<1 month) (OR=1.994), bed rest (> 72 h)(OR=3.897), history of superficial or deep vein or pulmonary embolism (OR=13.517) and family history of blood embolism (OR=6.551) were independent risk factors for DVT in patients after TKA (all P<0.05). The risk of DVT was 13.457 and 2.739 times higher in high and moderate risk TKA patients with Caprini MRAM classification, respectively.@*CONCLUSION@#Caprini MRAM can be used to predict the risk of DVT in patients after TKA, especially for patients with high risk.

ABSTRACT

Biliary malignant tumors have an insidious onset and rapid development, and most patients have lost the opportunity for radical surgery at initial diagnosis and often have poor prognosis. Gemcitabine-based chemotherapy is the first-line treatment for biliary malignant tumors, but with a limited clinical effect. The improvement in next-generation sequencing technology provides the possibility for the precise treatment of biliary malignant tumors, but the application and development of the precise treatment of biliary malignant tumors are limited by the low positive rate of targets and the poor accessibility of therapeutic drugs. The advent of the era of immunotherapy represented by the immune checkpoint inhibitor PD1/PD-L1 monoclonal antibody brings a promising future for the treatment of malignant tumors, including biliary malignant tumors. Combined chemotherapy and/or targeted therapy based on immune checkpoint inhibitors has shown a good effect in the treatment of biliary malignant tumors, which is the direction of the treatment of advanced biliary malignant tumors in the future.

ABSTRACT

Objective To investigate the health-seeking behaviors of imported malaria cases after returning to China, and to investigate the factors affecting the time to initial diagnosis, so as to provide the scientific evidence for early identification of imported malaria cases and prevention of severe cases development and secondary transmission. Methods The individual demographic features, and the disease onset and the time to initial diagnosis of imported malaria cases in Jiangsu Province in 2019 were captured from the National Notifiable Disease Report System and the Information Management System for Parasitic Disease Control in China. The characteristics of health-seeking behaviors and epidemiological features of imported malaria cases were descriptively analyzed, and the factors affecting the time to initial diagnosis of imported malaria cases after returning to China were identified using multivariate logistic regression analysis. Results A total of 244 imported malaria cases were reported in Jiangsu Province in 2019, and the time to initial diagnosis of the cases were 1-12 days, with mean time of (1.53 ± 1.65) days, with median time of one day. The highest number of malaria cases seeking healthcare services were found on the day of developing primary symptoms (76 cases, 31.1%), followed by on the second day (68 cases, 27.9%), on the third day (46 cases, 18.9%), and 54 cases (22.1%) received initial diagnosis 3 days following presence of primary symptoms, including 3 cases with initial diagnosis at more than one week. High proportions of imported malaria cases with a delay in the time to initial diagnosis were seen in migrant workers who returned to China in January (14 cases, 5.7%) and December (13 cases, 5.3%) and those aged between 41 and 50 years (32 cases, 13.1%). Multivariate logistic regression analysis showed relative short time to initial diagnosis among imported malaria cases returning to China on March [odds ratio (OR) = 0.16, P = 0.03, 95% confidence interval (CI): (0.03, 0.85)] and those with a history of overseas malaria parasite infections [OR = 0.36, P = 0.001, 95% CI: (0.19, 0.67)]. Conclusions Timely health-seeking behaviors should be improved among imported malaria cases in Jiangsu Province, patients with a history of overseas malaria infections require faster health-seeking activities.

ABSTRACT

Malaria was one for the most serious communicable diseases in China. Following the concerted efforts for decades, remarkable achievements have been gained for malaria control in China. Since the national malaria elimination programme was initiated in China in 2010, local malaria transmission was rapidly interrupted, with zero indigenous malaria case reported for the first time in the country in 2017, and the country will undergo the certification of malaria elimination by WHO. Currently, however, malaria remains hyper-endemic across the world. In China, there are more than 2 000 overseas imported malaria cases each year, and prevention of re-establishment of imported malaria will become the major task in future malaria control activities. Here by, we analyze the main challenges in the prevention of re-establishment of imported malaria in China, and propose the corresponding countermeasures, so as to provide insights into the consolidation of malaria elimination achievements.

ABSTRACT

Objective To analyze the changes of small molecular metabolites in the larvae of a deltamethrin-sensitive strain of Anopheles sinensis following exposure to deltamethrin, so as to provide the scientific basis for investigating the metabolic pathway and screening metabolic markers of deltamethrin in An. sinensis. Methods The 50% and 75% lethal concentrations (LC50 and LC75) of deltamethrin against the larvae of a deltamethrin-sensitive strain of An. sinensis were calculated in laboratory. The type and content of An. sinensis larvae metabolites were detected using high performance liquid chromatography and mass spectrometry (LC-MS/MS) following exposure to deltamethrin at LC50 and LC75 for 30 min and 24 h, and the changes of metabolites were analyzed. Results The LC50 and LC75 values of deltamethrin were 4.36 × 10-3 µg/mL and 1.12 × 10-2 µg/mL against thelarvae of a deltamethrin-sensitive strain of An. sinensis. Following exposure of the larvae of a deltamethrin-sensitive strain of An. sinensis to deltamethrin at LC50 and LC75 for 30 min, the differential metabolites mainly included organic oxygen compounds, carboxylic acid and its derivatives, fatty acyl and pyrimidine nucleotides, with reduced glucose levels. Following exposure for 24 h, the differential metabolites mainly included organic oxygen compounds, carboxylic acid and its derivatives, aliphatic acyl and purine nucleotides, with increased glucose level detected. Conclusion Carbohydrate, carboxylic acid and its derivatives, fatty acyls, amino acids and their derivatives may play important roles in deltamethrin metabolism in the larvae of a deltamethrin-sensitive strain of An. sinensis.

ABSTRACT

Objective:To evaluate the short-type single balloon enteroscope (SBE) to endoscopic retrograde cholangiopancreatography (ERCP) in patients with Roux-en-Y anastomosis.Methods:Data of 10 patients with Roux-en-Y anastomosis who received short-type SBE assisting ERCP (14 times of ERCP, the short-type SBE group) from May 2019 to September 2019 and 55 patients who received conventional SBE assisting ERCP (87 times of ERCP, the conventional SBE group) from March 2016 to April 2019 were collected in Nanjing Drum Tower Hospital. Success rates and mean time of reaching the blind loop, diagnosis and treatment success rates, procedure time and complication incidence in the two groups were compared.Results:The mean time to reach the blind loop was significantly shorter in short-type SBE group than that in the conventional SBE group (17.1 min VS 23.4 min, P = 0.04). There were no significant differences in success rates of reaching the blind loop[100.0%(14/14) VS 95.4%(83/87)], the success rates of diagnosis and treatment[both 100.0% (14/14) VS 100.0% (83/83)], the mean procedure time (62.6 min VS 64.3 min) or complication incidence [21.4%(3/14) VS 16.1% (14/83) ] between the two groups (all P>0.05). Conclusion:ERCP assisted by either type of SBE is safe and effective in patients with Roux-en-Y anastomosis. However, short-type SBE is faster to reach the blind loop because of its unique design and easier manipulation.

ABSTRACT

Objective To investigate the prevalence of soil-transmitted nematode human infections in Jurong City from 2016 to 2020, so as to provide the scientific evidence for formulating the control strategy. Methods During the period from 2016 to 2020, the permanent residents at ages of over 3 years living in Jurong City were selected as the study subjects. Stool samples were collected for the detection of soil-transmitted nematode eggs using the modified Kato-Katz thick smear method (two detections for one stool sample), and the species of hookworm was identified in stool-positive stool samples using the culture method. The prevalence and intensity of soil-transmitted nematode infections were calculated, and the change of the infection prevalence among years was examined using the Cochran-Armitage test for trend. Results A total of 10 011 people-time populations were detected for soil-transmitted nematode infections in Jurong City from 2016 to 2020, and 56 egg-positives were identified, with mean prevalence of 0.56%. The prevalence of soil-transmitted nematode human infections appeared a tendency towards a decline year by year in Jurong City (χ2trend = 5.15, P < 0.01). The mean prevalence of hookworm, Ascaris lumbricoides and Trichuris trichiura infections was 0.44%, 0.11% and 0.20% in Jurong City from 2016 to 2020, respectively, and individuals with hookworm infections accounted for 78.57% of all cases with soil-transmitted nematode infections. Single parasite (98.21%) and mild infection were pre-dominant in individuals with soil-transmitted nematode infections, and no multiple infections were seen after 2016. Conclusions The prevalence of human soil-transmitted nematodiasis is low in Jurong City. Based on reinforcement of soil-transmitted nematodiasis surveillance, an increase in the health education investment is required to consolidate the control achievements.

ABSTRACT

Objective To investigate the role of fatty acid binding protein 4 (FABP4) in the apoptosis of mouse podocytes induced by hyperhomocysteinemia (HHcy). Methods Nine wild male C57BL/6J mice (Cbs+/+) and nine C57BL/6J male mice with cystathionine beta synthase gene knockout heterozygote (Cbs+/-) were used as the control group and HHcy model group, respectively. All mice were fed with 2% high methionine diet for 8 weeks to replicate the HHcy model. The ultrastructure of glomerular podocytes was observed by transmission electron microscopy. Glomerular podocytes were cultured in vitro and divided into blank control group (Control group) podocytes treated with Hcy concentration of 0 μmol•L-1 for 48 hours. The podocytes of homocysteine group (Hcy group) were treated with Hcy concentration of 80 μmol•L-1 for 48 hours. Podocytes were infected with GFP-labeled adenovirus (Ad-GFP group) and FABP4 overexpression adenovirus (Ad-FABP4 group), respectively. Podocytes were treated with Hcy and FABP4 adenovirus, named as Hcy+Ad-FABP4 group. The expression of FABP4 was detected by qRT-PCR and Western blot. The changes of apoptosis-related proteins Bax, Bcl-2 and Caspase-12 were analyzed by Western blot. The apoptosis rate of cells was measured by flow cytometry. Results Compared with the control group, the podocyte injury was aggravated and accompanied by the increasing number of apoptotic cells in the kidney tissues of model group mice. At the same time, the expression of FABP4 mRNA (3.20±0.42) and protein (4.98±1.12) in model group were higher than those in control group (2.09±0.13, 3.04±0.11)(P0.05); the mRNA expression levels (4.59±0.28) and protein expression (10.07±0.82) of FABP4 in Ad-FABP4 group were higher than those in Ad-GFP group (P<0.05). Bax/Bcl-2 value (3.15±0.65) and Caspase-12 protein expression (4.30±0.89) in Hcy group were higher than those in control group (2.19±0.10, 3.19±0.47) (P<0.05). The Bax/Bcl-2 values (5.42±0.55) and Caspase-12 protein expression (7.87±1.27) in the Hcy+Ad-FABP4 group were significantly higher than those in the Hcy+Ad-GFP group (3.19±0.47, 4.34±0.64) (P<0.05). FABP4 plays an important role in the apoptosis of mouse podocytes induced by HHcy. Flow cytometry analysis showed that the total apoptotic rate of Hcy group was (10.85±1.25) higher than that of control group (3.77±0.12) (P<0.05). Hcy + Ad-FABP4 group (15.72±1.60) was higher than that of Hcy+Ad-GFP group (11.22±0.43) (P< 0.05). Conclusion FABP4 promotes the apoptosis of podocytes in mice treated with HHcy.

ABSTRACT

Objective:To investigate the value of serum C -reactive protein/prealbumin ratio (CRP/PA) in predicting the disease progression of adult patients with traumatic brain injury. Methods:A prospective study was conducted. Patients with traumatic brain injury who were over 18 years old and were followed up for more than 72 hours admitted to the department of emergency of Huashan North Hospital Affiliated to Fudan University from May 2018 to December 2019 were enrolled. The levels of serum CRP, PA were measured immediately after injury and at 6, 24, 48 and 72 hours after injury, and the CRP/PA ratio was calculated. Glasgow coma score (GCS) was dynamically measured and head CT was reviewed regularly. If the GCS decreased by more than 3 and/or the intracranial injury was aggravated by CT scan within 72 hours after injury, the patients were included in the aggravating group. If there were no above changes, they were included in the stable group. The differences of each index between the two groups were compared, and the receiver operating characteristic (ROC) curve was drawn to evaluate the predictive value of each index at different time points on the patient's disease progress.Results:A total of 106 patients were selected, including 89 patients in the stable group and 17 patients in the aggravating group, and the baseline data of the two groups were balanced. CRP, CRP/PA increased and PA decreased in brain trauma patients 6 hours after injury, and reached the peak value or valley value at 48 hours. Compared with the stable group, CRP/PA significantly increased at 24, 48 and 72 hours in the aggravating group [24 hours: 34.18 (20.19, 67.10) vs. 13.98 (4.36, 38.30), 48 hours: 71.10 (45.55, 96.97) vs. 16.02 (5.05, 41.76), 72 hours: 23.25 (4.46, 38.61) vs. 4.72 (2.38, 12.95), all P < 0.05]. ROC curve analysis showed that CRP/PA ratio at 24 hours and 48 hours after injury could be used as a predictor of disease progression. The area under the ROC curve (AUC) of 24 hours CRP/PA was 0.71, 95% confidence interval (95% CI) was 0.58-0.84, the cut -off value was 28.29, the sensitivity was 76.5%, and the specificity was 73.0%. The AUC of 48 hours CRP/PA was 0.76, 95% CI was 0.62-0.90, and the cut -off value was 37.18, the sensitivity was 88.2%, and the specificity was 70.8%. Conclusion:The dynamic monitoring of CRP/PA ratio in adult after traumatic brain injury can evaluate the disease condition, and the CRP/PA ratio of 24 hours and 48 hours can predict the progress of the disease.

ABSTRACT

Objective:To evaluate the clinical effect of self-made Maju-Zhiyang Decoction combined with loratadine tablets in the treatment of the children with atopic dermatitis and dampness-heat TCM syndrome. Methods:A total of 86 children with atopic dermatitis and dampness-heat syndrome in our hospital from January 2017 to May 2018 were selected and divided into two groups according to the random number table method, with 43 patients in each group. Patients in the control group were given loratadine tablets, while patients in the observation group were given self-made Maju-Zhiyang Decoction on this basis. Both groups were treated continuously for 2 weeks. The mossy lesion, scratch, exudative scab and erythema were evaluated before and after treatment. The severity of skin lesions was evaluated by Scoring Atopic Dermatitis Index (SCORAD). The multi-functional skin detector was used to detect transepidermal water loss (TEWL), the moisture content of the stratum corneum and the skin grease. The levels of IL-17, IL-33 and IgE were detected by double antibody sandwich ELISA. The adverse reactions during treatment were observed and recorded, and the clinical efficacy was evaluated. Results:The total effective rate was 93.0% (40/43) in the treatment group and 74.4% (32/43) in the control group, and the difference was statistically significant ( χ2=5.742, P<0.01). After treatment, the mossy, scratch, exudative scab, erythema scores and SCORAD scores in the observation group were significantly lower than those in the control group ( t values were 2.630, 8.779, 6.352, 5.264 and 9.115, respectively, P<0.01 or P<0.05), and the serum IL-17, IL-33 and IgE levels were significantly lower than those in the control group ( t values were 7.358, 19.285 and 135.049, respectively, all Ps<0.001). After treatment, the TEWL (9.77 ± 2.37 g/h?cm -2vs. 20.53 ± 3.89 g/h?cm -2, t=5.073) in the observation group was significantly lower than that of the control group ( P<0.01), the cuticle moisture content (27.16% ± 5.06% vs. 13.83% ± 2.71%, t=-8.552), and skin oil content (124.20 ± 3.29 g/cm 2vs. 90.17 ± 2.36 g/cm 2, t=-21.173) were significantly higher than those in the control group ( P<0.01). The incidence of adverse reactions in the treatment group was significantly lower than that of the control group ( χ2=9.437, P<0.05), which 4.7% (2/43) in the treatment group and 23.3% (2/43) in the control group. Conclusions:The self-made Maju-Zhiyang Decoction combined with loratadine tablets can alleviate the skin lesion symptoms of children with atopic dermatitis caused by dampness and heat, improve the skin barrier function, reduce the serum IL-17, IL-33 and IgE levels of children, and ensure the safety of drug use.
