ABSTRACT

Objective: To evaluate the recognition of acute respiratory infection (ARI) by a pretrained model based on electronic medical records (EMRs). Methods: 38 581 EMRs were obtained from Chongqing University Three Gorges Hospital in December 2021. Bidirectional encoder representation from transformers (BERT) pretrained model was used to identify ARI in EMRs. The results of medical professionals were considered as the gold standard to calculate the sensitivity, specificity, Kappa value, and area under the curve of the receiver operating characteristic (AUC). Results: There were 3 817 EMRs in the test set, with 1 200 ARIs. A total of 1 205 cases were determined as ARI by the model, with a sensitivity of 92.67% (1 112/1 200) and a specificity of 96.45% (2 524/2 617). The model identified ARI with similar accuracy in males and females (AUCs 0.95 and 0.94, respectively), and was more accurate in identifying ARI cases in those aged less than 18 than in adults 18-59 and adults 60 and older (AUCs 0.94, 0.89 and 0.94, respectively). The current model had a better identification of ARIs in outpatient patients than that in hospitalized patients, with AUCs of 0.74 and 0.95, respectively. Conclusion: The use of the BERT pretrained model based on EMRs has a good performance in the recognition of ARI cases, especially for the outpatients and juveniles. It shows a great potential to be applied to the monitoring of ARI cases in medical institutions.

ABSTRACT

OBJECTIVE@#To compare the clinical efficacy between auricular point sticking combined with transcutaneous electrical acupoint stimulation (TEAS) and nicotine patch for smoking cessation.@*METHODS@#Two hundred patients who voluntarily quit smoking were randomly divided into a combination group and a nicotine patch group, 100 cases in each group. In the combination group, auricular point sticking (Shenmen [TF4], Neifenmi [CO18], Pizhixia [AT4], Jiaogan [AH6a], etc., once every other day) combined with TEAS(Lieque [LU 7] and Zusanli [ST 36], with continuous wave, 20 Hz in frequency, 1 mA in current intensity, 30 min each time, once a day) were applied. In the nicotine patch group, nicotine patch was applied. Both groups were treated for 8 weeks. The immediate withdrawal rate and persistent withdrawal rate 8 weeks into treatment and in follow-up of 16 weeks after treatment in the two groups were compared; before treatment, 8 weeks into treatment and in follow-up of 16 weeks after treatment, the degree of nicotine dependence was evaluated by using Fagerström test for nicotine dependence (FTND); 1 week into treatment, 8 weeks into treatment and in follow-up of 16 weeks after treatment, the withdrawal symptoms and smoking craving were evaluated by using Minnesota nicotine withdrawal scale (MNWS); the safety and compliance (dropped off rate and treatment completeness) were evaluated in the two groups.@*RESULTS@#There was no statistical significance of the differences in the immediate withdrawal rate and persistent withdrawal rate 8 weeks into treatment and during follow-up between the two groups (P>0.05). The FTND scores were decreased 8 weeks into treatment and during follow-up in the two groups compared with those before treatment (P<0.01); the FTND score during follow-up in the combination group was lower than the nicotine patch group (P<0.05). The MNWS scores were decreased 8 weeks into treatment and during follow-up in the two groups compared with those 1 week into treatment (P<0.05); the changes of MNWS scores 8 weeks into treatment and during follow-up in the combination group were greater than the nicotine patch group (P<0.05, P<0.01). There were no serious adverse reactions in either group. Eight weeks into treatment and during follow-up, the dropped off rates were all 16.0% (16/100) in the combination group, which were 20.0% (20/100) and 23.0% (23/100) in the nicotine patch group, there was no statistical significance of the differences in the two groups (P>0.05). There was no significant difference in treatment completeness between the two groups (P>0.05).@*CONCLUSION@#Auricular point sticking combined with TEAS could effective decrease the degree of nicotine dependence, improve withdrawal symptoms in smokers, its effect is superior to nicotine patch.

ABSTRACT

Objective To investigate the short-term mortality of transcatheter arterial chemoembolization (TACE) in patients with primary liver cancer, and explore the possible causes of death and countermeasures. Methods All patients who underwent TACE at the Department of Interventional Radiology, First Affiliated Hospital of Soochow University from January 2015 to December 2020 were studied, but those with metastatic liver cancer or receiving combined treatment were excluded. The clinical and imaging data of all patients were collected before and 30 days after TACE, and the clinical characteristics of the patients with short-term postoperative death were analyzed. Death within 30 days after TACE was defined as short-term death. Results A total of 1466 TACE in 741 patients with primary liver cancer were included. Ten patients (10/741, 1.35%) died within 30 days after TACE, with a mortality rate of 0.68% for all TACE. The mortality rate of d-TACE and c-TACE was 1.62% (3/185) and 0.55 % (7/1281), respectively. The mortality rates of patients at China Liver Cancer Staging Ⅰ, Ⅱ, and Ⅲ stages were 0.45% (2/448), 0.33% (2/599), and 1.43% (6/419), respectively. The mean diameter of the largest lesion in death cases was 10.1±0.8 cm. The possible causes of death were liver failure (4 cases), rupture bleeding (3 cases), myelotoxicity (1 case), pulmonary embolism (1 case), and heart failure (1 case). Conclusion The mortality rate after TACE in patients with primary liver cancer is low, with occasional short-term postoperative deaths. The death cases are characterized by a large tumor volume, and the most common causes of short-term death are liver failure and rupture bleeding.

ABSTRACT

OBJECTIVE@#To compare the efficacy of different acupuncture frequencies in tobacco-dependent patients and explore the impact of nicotine metabolite rate (NMR) on smoking cessation in the intervention with acupuncture.@*METHODS@#A total of 120 cases of tobacco-dependent patients were randomly divided into a high-frequency group (60 cases, 12 cases dropped off) and a low-frequency group (60 cases, 6 cases dropped off). In the two groups, smoking cessation counseling was provided prior to acupuncture. Acupuncture was applied to Baihui (GV 20), Lieque (LU 7), Zusanli (ST 36), etc. Additionally, electric stimulation was added at Lieque (LU 7) and Zusanli (ST 36), with continuous wave, 15 Hz in frequency. The duration of treatment was 8 weeks in either group. In the high-frequency group, the treatment was given 5 times weekly from week 1 to week 4, and was 3 times weekly from week 5 to week 8. In the low-frequency group, the treatment was given 3 times weekly from week 1 to week 4, and was twice a week from week 5 to week 8. The immediate withdrawal rate, persistent withdrawal rate, the score of Fagerstrőm test for nicotine dependence (FTND) before and after treatment, as well as the score of Minnesota nicotine withdrawal scale (MNWS) in 1 and 8 weeks of treatment were compared among the patients with high and low NMR between the two groups separately. The Logistic regression analysis was used to screen the influencing factors of smoking cessation in the intervention with acupuncture.@*RESULTS@#After treatment, there was no statistical significance of the differences in the immediate withdrawal rate (35.4% [17/48] vs 29.6% [16/54]) and the persistent withdrawal rate (33.3% [16/48] vs 25.9% [14/54]) between the high-frequency group and the low-frequency group (P>0.05). The difference in withdrawal rate had no statistical significance between high and low NMR patients (P>0.05). FTND scores after treatment were lower than those before treatment (P<0.01) and MNWS scores were lower than those in 1 week of treatment (P<0.01) in the two groups. However, the differences had no statistical significance between the two groups and between the patients with high NMR and low NMR (P>0.05). Age, education level and NMR were the influencing factors of smoking cessation in the intervention with acupuncture (P<0.05).@*CONCLUSION@#Acupuncture with different frequencies has no obvious impact on the efficacy in tobacco-dependent patients. The lower nicotine metabolite rate in individuals, the better efficacy of acupuncture. The smokers with high nicotine metabolite rate may obtain a better effect of cessation in the high-frequency intervention with acupuncture.

ABSTRACT

Studies have shown that the type 2 inflammatory response and related cytokines such as interleukin-4 and -13, play a key role in atopic dermatitis (AD) . Th2 cells and type 2 cytokines are the core factors in the type 2 inflammatory response, which is mainly involved in the pathogenesis of AD through 3 pathways: aggravating skin barrier defects; activating and strengthening the itching response; pathologically reprograming regulatory T cells into Th2-like regulatory T cells to amplify the type 2 inflammatory response. This review explores the relationship between the type 2 inflammatory response and AD, aiming to help optimize treatment regimens and provide new treatment options for patients with AD.

ABSTRACT

Objective To learn the density, distribution, population composition, and seasonal fluctuation of mosquitoes in Shanghai Pudong New Area, and to provide evidence for the mosquito-borne diseases control and prevention. Methods From 2017 to 2019, light trap method was used to monitor the mosquito density in farmyard, parks, hospitals, residential areas and the barns, three times a month from April to November. Results A total of 24 times/set light traps were set up and 7 104 mosquitoes were captured.The average density was 3.07 insects per lamp.Culex pipienspallens (81.52%) and Aedes albopictus (12.10%) were the mostly captured, followed by Armigeres subalbatus (3.24%), Culex tritaeniorhynchus (2.78%) and Anopheles sinensis (0.36%).The proportion of Culex pipienspallens was increasing year by year, and that of Aedes albopictus was decreasing year by year.The seasonal variation curve of mosquito density showed a single peak distribution, with the peak from June to July.Among the five habitat types, the mosquito density from high to low was hospital (4.68/set), farmyard (4.38/set), livestock shed (3.25/set), residential household (2.81/set) and park (1.38/set).The mosquito density in urban area, urban-rural junction and rural area was 2.69, 3.32 and 3.36 respectively (i.e., rural area > urban-rural integration > urban area). Conclusion Culex pipienspallens and Aedes albopictus are the dominant species in Pudong New Area.Parks, hospitals and residential areas are the most important mosquitoes infestation areas, therefore more attention must be paid to mosquito control in these areas.

ABSTRACT

Objective To observe the clinical efficacy of Huajian-Badu membrane in the treatment of moderate and severe cancer pain. Methods The 80 malignant tumor patients with moderate to severe cancer pain from January 2016 to June 2017 in Tianjin University of Traditional Chinese Medicine First Teaching Hospital were recruited and randomly divided into the observation group and the control group, each of 40 cases. The control group were treated with Oxycodone Hydrochloride Prolonged-release Tablets, while the treatment group were treated with Huajian-Badu membrane on the basis of the treatment in control group. The pain relief, pain frequency, morphine consumption and quality of life (Karnofsky score), adverse reaction were evaluated between two groups before and after treatment. Results Compared with the control group, the total efficiency in the observation group was significantly higher (95.0% vs. 80.0%, χ2=4.114, P=0.043). The frequency of breakthrough pain of two groups increased on the seventh and fourteenth treatment days(0.3 ± 0.6 times vs. 0.8 ± 0.7 times, t=-3.430 and 0.4 ± 0.6 times vs. 0.9 ± 0.8 times, t=-3.162), but the number of outbreaks of pain in the observation group significantly less than the control group (P<0.05 or P<0.01). The morphine injection dosage increased on the seventh and fourteenth treatment days (3.01 ± 4.28 g vs. 5.62 ± 6.37 g, t=-2.151 and 3.21 ± 4.32 g vs. 7.84 ± 7.76 g, t=-3.297), but the amount of the observtation group was significantly lower than that of control group (P<0.05 or P<0.01). The KPS score in the observation group increased significantly, and significantly higher than the control group on the seventh and fourteenth treatment days (73.0 ± 15.0 vs. 66.0 ± 12.0, t=2.305 and 77.0 ± 13.0 vs. 70.0 ± 15.0, t=2.230, P<0.05). The adverse reaction rate of the control group was 25%, while the the observation group was 20%. The difference between two groups was significant (χ2=0.287, P=0.592). Conclusions The Huajian-Badu membrane combined Oxycodone Hydrochloride Prolonged-release Tablets can improve the total effective rate of pain relief, reduce the number of outbreaks, reduce morphine consumption, improve patient KPS score of the patients with cancer pain.

ABSTRACT

Background:@#The use of mobile phone significantly improved the outcomes of tobacco cessation. However, its feasibility and acceptability were unclear in the Chinese population. This study was to explore the feasibility of using Wi-Fi access points (APs) as a platform to provide smoking cessation help at 17 airports and 38 railway stations across China.@*Methods:@#This study was divided into two stages: platform development and population survey. In the first stage, a survey platform was developed and incorporated into Wi-Fi service at airports and railway stations, which could provide survey content as a pop-up window when participants tried to access the Wi-Fi service. In the second stage, a population survey was conducted to explore the intention to receive tobacco cessation support.@*Results:@#A total of 20,199 users participated and 13,628 users submitted the survey, with a response rate of 67.47%. The smoking rate was 30.9%. A total of 86.58% of smoking participants and 2.44% of non-smoking participants wished to receive tobacco cessation support, respectively. The multivariate analysis showed intention to receive support did not differ in age, gender, and heaviness of smoking (P > 0.05).@*Conclusion:@#Providing tobacco cessation support via Wi-Fi APs is feasible and efficient, and smokers have high intention to receive tobacco cessation support. It is suggested hospitals, academia, information technology industries, and government agencies must work together to provide tobacco cessation support via mHealth.

Objective To evaluate percutaneous mechanical thrombectomy and angioplasty in patients with femoropopliteal artery stent restenosis.Methods The clinical data of 41 cases with critical limb ischemia caused by femoropopliteal artery stent restenosis were analyzed retrospectively from Jun 2015 to May 2017,who were treated by percutaneous mechanical thrombectomy (PMT) + percutaneous angioplasty (PTA) simultaneously.Clinical status assessment,ankle brachial index (ABI) test and color duplex ultrasonography (CDU) were administered at 3rd,6th and 12th month during follow-up;and computed tomography angiography (CTA) or digital subtraction angiography (DSA) was performed at 6th and 12th month after discharged.Results Procedures were successful in all patients.27 cases were under PTA after PMT,other 14 cases were under PTA + stenting after PMT.The average ABI increased from 0.34 ± 0.28 to 0.84 ± 0.32 (P =0.00) immediately.There was no perioperative death and major limb amputation.36 cases (36/41,87.8%) were followed-up from 169 to 698 days (mean 426 days).During follow-up of 12 months,there were 18 cases with in-stent restenosis and/or thrombosis.PMT + PTA were performed again in 14 cases and 4 cases accepted medication;no case encountered major amputation.The primary patency and second patency were 82.9% and 97.6% respectively at 6th month;Which were 49.8% and 88.8% respectively at 12th month,and the ABI was 0.65 ± 0.10 (P =0.01).Conclusion Percutaneous mechanical thrombectomy and angioplasty is safe,miniinvasive and effective for femoropoplitealartery stent restenosis.

ABSTRACT

Objective To establish a method for in vitro expansion of regulatory T cells (Tregs)for clinical study and immunotherapy.Methods CD4 + T cells were isolated from BALB/c spleens by magnetic activated cell sorting (MACS),then cultured in 24-well plates coated with anti-CD3/CD28 microbeads in the presence of 100 U/ml interleukin-2 (IL-2) and 5 ng/ml recombinant human transforming growth factor-β (rhTGF-β).The purity of the expanded Tregs were tested by flow cytometry.In vitro inhibition of CD4 + CD25-T cells response by expanded Tregs was measured by mixed lymphocyte reaction test.The number and the viability of the expanded Tregs were detemined by trypan blue staining.Results Tregs were expanded up to 20 folds after 5 days in culture,and the activity was (93 ± 4) %.The purity of expanded Tregs were (79.1 ± 1.5) %,and maintained suppressive ability.Conclusions We can obtain large numbers of Tregs with highly purity and suppressive ability,thereby providing a solution to the availability of sufficient Tregs in clinical study and immunotherapy.
