RESUMO
@#Objective To recognize the different phases of Korotkoff sounds through deep learning technology, so as to improve the accuracy of blood pressure measurement in different populations. Methods A classification model of the Korotkoff sounds phases was designed, which fused attention mechanism (Attention), residual network (ResNet) and bidirectional long short-term memory (BiLSTM). First, a single Korotkoff sound signal was extracted from the whole Korotkoff sounds signals beat by beat, and each Korotkoff sound signal was converted into a Mel spectrogram. Then, the local feature extraction of Mel spectrogram was processed by using the Attention mechanism and ResNet network, and BiLSTM network was used to deal with the temporal relations between features, and full-connection layer network was applied in reducing the dimension of features. Finally, the classification was completed by SoftMax function. The dataset used in this study was collected from 44 volunteers (24 females, 20 males with an average age of 36 years), and the model performance was verified using 10-fold cross-validation. Results The classification accuracy of the established model for the 5 types of Korotkoff sounds phases was 93.4%, which was higher than that of other models. Conclusion This study proves that the deep learning method can accurately classify Korotkoff sounds phases, which lays a strong technical foundation for the subsequent design of automatic blood pressure measurement methods based on the classification of the Korotkoff sounds phases.
RESUMO
Objective: To explore the characteristics, patterns of multimorbidity and the impact on quality of life and the prognosis of middle-aged and elderly patients with chronic obstructive pulmonary disease (COPD). Methods: This is a cross-sectional study. From January 2012 to December 2021, 939 middle-aged and elderly COPD patients hospitalized in Beijing Hospital were selected by the convenient sampling method. The basic data of patients and the date of 16 common chronic diseases were collected. Patterns of multimorbidity were depicted by cluster analysis. Generalized linear regression model and logistic regression were used to evaluate the multimorbidity patterns and their prognosis. Results: At least one multimorbidity existed among 93.40% of COPD patients, and the median number of multimorbidity was 3. The top five multimorbidity among the patients were hypertension (57.93%, 544/939), coronary heart disease (33.76%,317/939), heart failure (31.95%,300/939), hyperlipidemia (31.63%,297/939) and arrhythmia (27.37%,257/939). Four multimorbidity patterns were identified, cardiometabolic and metabolic multimorbidity, kidney disease multimorbidity, respiratory-digestive-tumor multimorbidity and other multimorbidity. Cardiometabolic and metabolic multimorbidity was most common (590/939, 62.83%). Compared with non-cardiometabolic and metabolic multimorbidity, the incharge ADL score of patients with this multimorbidity decreased by 7 points (95%CI:-11.22- -3.34), Correspondingly, patients with kidney disease multimorbidity decreased by 14 points (95%CI:-24.12- -3.30) on the incharge score. The presence or absence of kidney disease multimorbidity had the greatest impact on discharge score, which was reduced by 12 points in comparison with patients without this multimorbidity (95%CI:-22.43- -2.40). ICU admission is mostly affected by the presence of cardiometabolic and metabolic multimorbidity (OR=2.44, 95%CI: 1.51-3.92) and kidney disease multimorbidity (OR=2.58, 95%CI: 1.01-6.60). The risk of death is the highest for cardiometabolic and metabolic multimorbidity (OR=2.24, 95%CI: 1.19-4.21). Conclusion: Multimorbidity is common in COPD patients. The most common pattern is cardiometabolic and metabolic multimorbidity. Cardiometabolic and metabolic multimorbidity and kidney disease multimorbidity significantly affect the quality of life and often associate with a poor prognosis.

@#Currently, in precision cardiac surgery, there are still some pressing issues that need to be addressed. For example, cardiopulmonary bypass remains a critical factor in precise surgical treatment, and many core aspects still rely on the experience and subjective judgment of cardiopulmonary bypass specialists and surgeons, lacking precise data feedback. With the increasing elderly population and rising surgical complexity, precise feedback during cardiopulmonary bypass becomes crucial for improving surgical success rates and facilitating high-complexity procedures. Overcoming these key challenges requires not only a solid medical background but also close collaboration among multiple interdisciplinary fields. Establishing a multidisciplinary team encompassing professionals from the medical, information, software, and related industries can provide high-quality solutions to these challenges. This article shows several patents from a collaborative medical and electronic information team, illustrating how to identify unresolved technical issues and find corresponding solutions in the field of precision cardiac surgery while sharing experiences in applying for invention patents.
RESUMO
OBJECTIVE@#To investigate the effects of composite Sophora colon-soluble Capsule (CSCC) on gut microbiota-mediated short-chain fatty acids (SCFAs) production and downstream group 3 innate lymphoid cells (ILC3s) of dextran sulfate sodium (DSS)-induced ulcerative colitis (UC) mice model.@*METHODS@#The main components of CSCC were analyzed by hybrid ultra-high-performance liquid chromatography ion mobility spectromety quadrupole time-of-flight mass spectrometry (UHPLC-IM-QTOF/MS). Twenty-four male BALB/c mice were randomly divided into 4 groups (n=6) by using a computer algorithm-generated random digital, including control, DSS model, mesalazine, and CSCC groups. A DSS-induced colitis mice model was established to determine the effects of CSCC by recording colonic weight, colonic length, index of colonic weight, and histological colonic score. The variations in ILC3s were assessed by immunofluorescence and flow cytometry. The results of gut microbiota and SCFAs were acquired by 16s rDNA and gas chromatography-mass spectrometry (GC-MS) analysis. The expression levels of NCR+ ILC3-, CCR6+ Nkp46- (Lti) ILC3-, and ILCreg-specific markers were detected by enzyme-linked immunosorbent assay, and real-time quantitative polymerase chain reaction and Western blot, respectively.@*RESULTS@#The main components of CSCC were matrine, ammothamnine, Sophora flavescens neoalcohol J, and Sophora oxytol U. After 7 days of treatment, CSCC significantly alleviated colitis by promoting the reproduction of intestinal probiotics manifested as upregulation of the abundance of Bacteroidetes species and specifically the Bacteroidales_S24-7 genus (P<0.05). Among the SCFAs, the content of butyric acid increased the most after CSCC treatment. Meanwhile, compared with the model group, Lti ILC3s and its biomarkers were significantly downregulated and NCR+ ILC3s were significantly elevated in the CSCC group (P<0.01). Further experiments revealed that ILC3s were differentiated from Lti ILC3s to NCR+ ILC3s, resulting in interleukin-22 production which regulates gut epithelial barrier function.@*CONCLUSION@#CSCC may exert a therapeutic effect on UC by improving the gut microbiota, promoting metabolite butyric acid production, and managing the ratio between NCR+ ILC3s and Lti ILC3s.

They were randomly assigned to receive either rTMS (control group, n = 45) or rTMS combined with health education (observation group, n = 45). All patients received 4 weeks of treatment. Clinical efficacy, the scores of the Clinical Global Impressions (CGI) Scale and the Hamilton Rating Scale for Depression (HAMD), cognitive function, sleep quality, and quality of life pre- and post-intervention were compared between the two groups. Results:Total response rate was significantly higher in the observation group than in the control group [91.11% (41/45) vs. 71.11% (32/45), χ2 = 5.87, P < 0.05]. CGI scores post-intervention were significantly higher in the observation group than in the control group [(45.23 ± 7.89) points vs. (27.64 ± 4.53) points, t = 12.97, P < 0.05]. HAMD scores were significantly lower in the observation group than in the control group [(16.32 ± 2.76) points vs. (21.86 ± 3.98) points, t = 7.67, P < 0.05]. The number of categories achieved and the number of correct responses post-intervention in the observation group were (3.83 ± 0.61) and (85.45 ± 7.87), respectively, which were significantly higher than those in the control group [(2.98 ± 0.37), (73.25 ± 6.12), t = 7.99, 8.20, both P < 0.05]. The number of perseverative errors post-intervention in the observation group was significantly lower than that in the control group [(32.02 ± 1.89) vs. (35.12 ± 2.09), t = 7.38, P < 0.05]. The Pittsburgh Sleep Quality Index post-intervention was significantly lower in the observation group than in the control group [(9.84 ± 1.56) points vs. (12.32 ± 1.62) points, t = 7.39, P < 0.05). The scores of social function, material well-being, physical function, and psychological function post-intervention in the observation group were (59.98 ± 5.31) points, (34.23 ± 4.12) points, (56.87 ± 5.32) points, and (47.28 ± 5.65) points, which were significantly higher than those in the control group [(45.23 ± 6.57) points, (27.98 ± 2.65) points, (43.24 ± 4.53) points, (36.21 ± 4.12) points, t = 11.71, 8.55, 13.08, 10.62, all P < 0.05]. Conclusion:rTMS combined with health education is highly effective on refractory depression. The combined therapy can improve cognitive function and sleep quality and is of great innovation and science.
RESUMO
AIM: To analyze the changes of uncorrected distance visual acuity(UCDVA)and ocular accommodation before and after excimer laser photorefractive keratectomy(PRK).METHODS: A retrospective study. There were 120 patients(240 eyes)who underwent PRK surgery in our center from December 2017 to December 2019 divided into two groups according to the diopter of spherical equivalent(SE): 70 cases with SE≤-6.00D in the mild to moderate myopia group and 50 cases with -6.00D<SE≤-9.00D in the high myopia group which were observed and analyzed. The UCDVA(LogMAR), monocular accommodative amplitude(AMP), negative relative accommodation(NRA), positive relative accommodation(PRA)and monocular accommodative flipper(AF)were measured before and after operation at 1wk, 1 and 3mo. RESULTS: In the group of low-moderate myopia and high-myopia group, the UCDVA at 1wk, 1 and 3 mo after operation was significantly increased compared with those before operation(all P<0.01). The increase of UCDVA of low to moderate myopia group was better than that in the high myopia group at 3mo after operation(P<0.05). Monocular AMP in the both groups firstly decreased and increased afterwards, and there was a significant decrease than that before operation at 1wk and 1mo after operation(P<0.01). AMP reached and was better than that before operation at 3mo after operation(P<0.01). The increase of low to moderate myopia group was both higher and faster than that of high myopia group. Compared with PRA before operation, the patients of low to moderate myopia group decreased at 1wk after operation(P<0.01), postoperative levels at 1mo recovered to preoperative level(P>0.05)and postoperative at 3mo was superior to preoperative operation(P<0.05); High myopia group did not change significantly at 1wk and 1mo after operation compared with preoperative operation(P>0.05), and increased at 3mo after operation compared with preoperative level(P<0.01). For low to moderate myopia group, there was no significant difference in preoperative and postoperative NRA, and at 1wk after operation, NRA of high myopia group temporarily increased compared with preoperative operation(P<0.01). At 1mo after operation, it returned to the preoperative level(P>0.05), and significantly increased at 3mo after operation compared with preoperative operation(P<0.01). Monocular AF for both groups significantly decreased at 1wk after operation compared with preoperative operation, recovered at 1mo after operation and was significantly better at 3mo after operation(all P<0.01); The low-to-moderate group increased more than the high-myopia group.CONCLUSION: PRK has a good correction effect for myopia below -9.00D, and people in low to moderate myopia have a better postoperative UCDVA correction effect than those in high myopia. The eye accommodation will be abnormal in a short period after operation. The recovery and improvement time of accommodative function in low-moderate myopia group are shorter than that in high myopia group, but both groups can recover and improve at 3mo after operation compared with the preoperative levels.
RESUMO
Objective: To compare and analyze the perioperative clinical effects of minimally invasive Ivor-Lewis esophagectomy (MIE-Ivor-Lewis) and minimally invasive McKeown esophagectomy (MIE-McKeown). Methods: A total of 147 patients who underwent endoscopic esophageal cancer surgery from April 2018 to August 2019 were selected, including 85 patients undergoing MIE-McKeown surgery and 62 patients undergoing MIE-Ivor-Lewis surgery. The measurement data were expressed as (x±s), the comparison of normally distributed measurement data was performed by independent sample t-test, and the comparison of count data was performed by χ(2) test or Fisher's exact test. Results: The operation time of McKeown (M) group and Ivor-Lewis (IL) group were (219.2±72.4) minutes and (225.8±65.3) minutes. The mediastinal lymph node dissection number of M and IL groups were 13.3±4.8 and 11.6±6.5, respectively. The number of left recurrent laryngeal nerve lymph node dissection were 3.5±1.2 and 3.1±1.4, respectively. The intraoperative blood loss were (178.3±41.3) ml and (163.2±64.1) ml, respectively. The number of patients reoperated for postoperative bleeding were 1 and 0, respectively. The number of patients with postoperative gastric bleeding were 0 and 1, respectively. The postoperative chest tube retention time were (2.8±1.3) days and (3.1±1.2) days, respectively. The number of patients with anastomotic leakage were 7 and 1, respectively. The number of patients with lung infection were 13 and 5, respectively, and with chylothorax were 2 and 1, respectively, without statistically significant difference (P>0.05). The number of patients with hoarseness were 11 and 3, respectively. The total incidence of complication were 41.2% (35/85) and 17.7% (11/62), and the postoperative hospital stay were (14.7±6.5) days and (12.3±2.3) days, with statistical difference (P<0.05). Conclusion: MIE-Ivor-Lewis and MIE-McKeown are safe and effective in treating esophageal cancer, but the complication of MIE-Ivor-Lewis is less than that of MIE-Mckeown, and the perioperative clinical effect of MIE-Ivor-Lewis is better than that of MIE-McKeown.

@#Objective To explore the anticoagulant strategy of adjusting the dose of warfarin at different stages after mechanical valve replacement of mitral valve. Methods Clinical data of a total of 302 patients, including 76 males and 226 females, with an average age of 50.1±10.1 years, who underwent mechanical mitral valve replacement in the Chinese adult cardiac surgery database from 2013 to 2017 were retrospectively analyzed. According to the dose adjustment strategy of taking warfarin, the patients were divided into a D group (adjusting warfarin dose in days) and a W group (adjusting warfarin dose in weeks) to evaluate the anti-coagulation effect of warfarin. Results The total follow-up time was 423 277 d (1 159.7 years). There was no significant difference in the overall anticoagulant strength, and the warfarin dose adjusted in days was better in the early postoperative period (P<0.05), especially in patients over 60 years. It was better to adjust warfarin dose in weeks in the middle and long periods (P<0.05), especially in patients ≤40 years. In terms of the stability of anticoagulation, it was better to adjust the dosage of warfarin in weeks (P<0.05). It was better to adjust the dosage of warfarin in weeks for early, middle- and long-term anticoagulant therapy after operation (P<0.05), especially in the females aged >40 and ≤50 years. Conclusion Within the target range of international normalized ratio (1.5-2.5), the anticoagulant strategy of adjusting warfarin dose in days after mechanical valve replacement of mitral valve can achieve a better anticoagulant strength, and adjusting the dosage of warfarin in weeks is better in the middle- and long-term after operation. In general, the anticoagulant effect is more stable in the short term when warfarin dose is adjusted on a weekly basis.

RESUMO
Objective@#To evaluate the effect of daily temperature on hand-foot-mouth disease (HFMD) in children under 5 years old in Jingzhou city.@*Methods@#HFMD incidence data and meteorological data in Jingzhou city were obtained during 2010 and 2017. Distributed lag non-linear model (DLNM) was utilized to investigate the impact of daily temperature on HFMD incidence among children under 5 years old adjusting for potential confounders of other meteorological factors, secular trend, weekdays and holidays.@*Results@#A total of 47 525 cases were reported during 2010 to 2017, of which the ratio of male to female was 1.52. Children under 1 year old, 1-<3 years old, 3-5 years old accounted for 9.72%, 62.10%, and 28.18% of the total cases, respectively. Children cared at home and children care in kindergarten accounted for 73.29% and 26.71% of the total cases, respectively. The relationship between the temperature and the daily cases of HFMD in children under five years old was a ‘M’ pattern. Compared with a reference temperature (the 50 th percentile of average temperature during the study period, P 50), the maximum value of effect at 8.21 ℃ and 25.81 ℃ were 1.53(95%CI=1.33-1.76) and 1.47(95%CI=1.31-1.65). Higher temperatures (such as 25.81 ℃ in this paper) showed a long lag effect on the HFMD incidence compared with lower temperatures (such as 8.21 ℃). Subgroup analyses indicated that children aged 3-5 years (children who attended daycare) were more vulnerable to the effects of temperature changes on HFMD than those under 1 year old and 1-<3-year-old (cared at home).@*Conclusion@#The temperature has a significant impact on the HFMD incidence among children under five years old in Jingzhou. Daycare centers is the key place for prevention and control of HFMD.
RESUMO
To investigate the morphologic characteristics of the retromaxillary posterior ethmoid.A total of 103 outpatients encountered in our hospital during March 2012 and December 2012,who completed paranasal sinus CT examination,were included in this study.Patients had no sinus trauma,surgery or tumor history.Their paranasal sinus CT scans were analyzed from scheduled axial and coronal plane.The incidence and imaging features of the retromaxillary posterior ethmoid were observed.The retromaxillary posterior ethmoid(RMPE)was the posterior ethmoid cell that expanded along the lamina papyracea toward the infraorbital region.RMPE was located behind the posterior wall of the maxillary sinus and under the orbital floor.The occurrence rate of the RMPE was 74.3%.The ethmomaxillary septum is the bony septum the between the maxillary sinus and posterior ethmoid.Anatomical confirmation of RMPE is based mainly on the presence of the ethmomaxillary septum.RMPE is located at the back of ethmomaxillary septum.The sagittal angulation of the ethmomaxillary septum ranged from 22 to 87 degrees,with an average of(50.34±12.10)degrees.The ethmomaxillary septum is important for anatomic recognition of the RMPE.Accurate identification of the RMPE before ESS can help improve the removal of the posterior ethmoid sinus.

We investigated the Toxop lasma infection prevalence among planned pregnant women in Chongqing ,and to pro‐vide reference for the first level intervention of birth defects in the region .A total of 11 953 planned pregnant women were se‐lected by proportionally stratified multi‐stage random sampling method .Questionnaire survey was given to the women ,and blood samples were collected .Specific IgM and IgG antibodies against Toxoplasma were detected with ELISA .Results showed that among the 11 953 cases surveyed ,Toxoplasma IgM was positive in 71 cases ,with the positive rate of 0 .59% ;IgG was positive in 771 cases ,with the positive rate of 6 .54% .The positive rate of IgM and IgG antibodies in the metropolitan core re‐gion of the city was higher than that in the suburb areas (χ2 =35 .28 ,P<0 .000 1 ;χ2 =82 .65 ,P<0 .000 1) .The positive rate of IgM antibody increased with the educational level (χ2trend=3 .25 ,P=0 .001 1) .The positive rates of IgM and IgG varied in occupations among women (χ2 =13 .93 , P= 0 .016 0;χ2 = 15 .58 ,χ2 =0 .008 1) ,with the highest rate of public officials . Planned pregnant women with the history of abnormal pregnancy outcomes had higher positive rate of T .gondii IgM and IgG antibodies than those in the control (χ2 =6 .85 ,P=0 .008 9;χ2 =59 .25 ,P<0 .000 1) .There was no significant difference of IgM positive rate between the planned pregnancy women who had closed contact to cats and the control group (χ2 =0 .23 ,P=0 .628 6) ,while the positive rate of IgG was higher than that of the control group (χ2 =9 .95 ,P=0 .001 6) .T .gondii infec‐tion rate was on the low level of planned pregnant women in Chongqing .Adverse pregnancy outcomes are related to Toxoplas‐ma infection .
RESUMO
Objective To screen thyroid function among planned pregnant women in Chongqing, to guide prenatal and postnatal care. Methods Proportional multi-stage stratified cluster random sampling method was adopted to enroll 11 953 planned pregnant women for questionnaire, physical examination, and serum samples collection. Results The median TSH was 2. 04 mIU/ L, P25 = 1. 36 mIU/ L,P75 = 2. 99 mIU/ L. TSH levels being normal, higher, and lower than the reference were 91. 47% , 6. 20% , and 2. 33% , respectively. In Northeast Chongqing, the proportions of median TSH level and TSH level above the upper limit were higher than those in other regions(P<0. 05). With improved education, proportions of TSH above the upper limit and below the lower limit declined(P<0. 05). With the increase in body mass index, the proportion of those whose TSH was above the upper limit showed elevated trend(P<0. 05). In women with history of adverse pregnancy outcomes, their median TSH was higher than that in the control group, and those, whose TSH level exceeded the upper limit, yield higher results than those in the control group(P<0. 05). In women with higher fasting blood glucose The median TSH level was lower than that in normal blood glucose group( P<0. 05), with the fasting plasma glucose concentration and TSH negatively correlated(P<0. 05). Conclusion The abnormal rate of TSH level in planned pregnant women was 8. 53% in Chongqing. The abnormal rate varies by different regions, education levels, body mass indexes, and blood glucose levels. Previous history of adverse pregnancy outcomes was related to elevated TSH levels. It is necessary to take pre-pregnancy thyroid function screening investigation.
RESUMO
The incidences of overweight and obesity in planned pregnant women in Chongqing were 24.15 % and 5.02%.Those living in southeast Chongqing,being old age,with primary school education,and unemployment are the key crowds and deserve health management in regard of overweight and obesity as well as reproduction.
RESUMO
Objective To investigate the characteristics of sagittal anatomic structure of the upper airway in patients with ankylosing spondylitis using three-dimensional reconstruction based on computed tomography (CT).Methods Thirty-one male patients with ankylosing spondylitis,aged 20-60 yr (AS group),and 41 common patients (male) without difficult airways,aged 20-60 yr (control group),who underwent spiral CT scan of the head and neck using Helical CT from January 2007 to February 2011 in our hospital,were enrolled in the study.Reconstructed images of the upper airway were obtained using AW4.4 workstation and six distances (D1-D6) and four angles (α-δ) were recorded and analyzed:(1)D1,the arc distance between the upper central incisor and root of epiglottis; D2,the distance between the upper central incisor and root of epiglottis; D3 and D4,the lengths of maxilla and mandible ; D5,the distance between the root of epiglottis and midpoint of glottis; D6,the distance between the end of mandible and midpoint of glottis; (2) angle α,the angle of line D2 and D5; angle β,the angle of line D2 and the lower edge of the upper central incisor to the midpoint of glottis; angle γ,the angle of line D4 and D6; angle δ,the angle of the point of the lower edge of the upper central incisor to the trailing edge of the hard palate and then to the root of epiglottis.Results Compared with control group,no significant change was found in D1,D2,D3,D4 and D5 (P > 0.05),and D6,angle α and angle δ were significantly increased,whereas angle β and angle γ were decreased in AS group (P < 0.05).Conclusion The anatomic structure of the upper airway has the characteristics of specific changes and a laryngoscope blade with a large degree of curvature may be helpful for successful tracheal intubation in patients with ankylosing spondylitis.
RESUMO
<p><b>OBJECTIVE</b>To evaluate the clinical efficacy and safety of Composite Sophora Colon-soluble Capsules (CSCC) in treating patients with ulcerative colitis (UC) of internal dampness-heat syndrome type (IDHS) and compared with that of Mesalazine slow releasing granules (trade name: Etiasa).</p><p><b>METHODS</b>Adopting randomized double-blinded double-simulated and positive drug controlled clinical design, 160 patients with UC of IDHS type were randomly assigned to two groups, 120 in the trial group was treated with CSCC plus Etiasa simulated placebo for 8 weeks, while 40 in the control group with Etiasa plus CSCC simulated placebo. Comprehensive therapeutic efficacy, effects on syndrome and safety of treatment were assessed, and changes of endoscopic features, Chinese medical syndrome scores and symptom score, activity index (AI) of UC, microscopic pathology in the two groups were observed and compared before and after treatment.</p><p><b>RESULTS</b>After 8-week treatment, the clinical total effective rate in the two groups were 92.0% and 83.3%, the effective rate on Chinese medical syndrome in them were 91.7% and 85.0%, that on endoscopic features 92.0% and 83.3%, on microscopic changes 66.7% and 52.0%, respectively, showing insignificant difference between groups. Difference between groups in AI also showed no significance (1.03 +/- 1.87 vs 1.78 +/- 2.18, P > 0.05). However, the effects of decreasing Chinese medical syndrome score, and improving mucous pus blood stool and foul defecation in the trial group were more significantly (P < 0.05). No serious adverse event was seen in the 8-week treatment period.</p><p><b>CONCLUSIONS</b>The clinical efficacy of CSCC was not inferior to, or even better than that of Etiasa. It could be taken as a substitute of chemicals if with poor effect.</p>
