Objective:To evaluate the incidence and case fatality rate of cardiovascular disease (CVD) among populations in urban and rural communities in eastern, central and western regions of China.Methods:The present study was based on the data of the Prospective Urban and Rural Epidemiology (PURE)-China cohort, which enrolled participants who had at least one follow-up visit and complete information on age and sex. Information on baseline demographics, cardiovascular risk factors, and prevention and treatment for CVD were collected. CVD and mortality events were documented using the standardized case report form of the PURE Global Study to assess the incidence and case fatality rate of CVD among populations in urban and rural communities in eastern, central and western China.Results:This study included a total of 47 262 community-dwelling participants (age: (51.1±9.6) years; female, n=27 529, 58.2%) from 115 urban and rural communities in 12 provinces across the eastern, central, and western regions of China. Over a follow-up period of 11.9 (9.5, 12.6) years, 2 686 deaths and 5 873 cardiovascular events were documented. The incidence of CVD was 11.90 (95%CI: 11.60-12.21)/1 000 person-years. A significant difference in CVD incidence was observed across regions ( Ptrend<0.001), which was highest in the western provinces (13.99 (95% CI: 13.33-14.65)/1 000 person-years), intermediate in the eastern provinces (11.92 (95% CI: 11.52-12.33)/1 000 person-years), and lowest in the central provinces (8.87 (95% CI: 8.25-9.50)/1 000 person-years). The 1-year case fatality rate of CVD demonstrated an increasing trend from eastern to western regions (eastern: 10.20% (95% CI: 6.95-14.73); central: 13.50% (95% CI: 9.90-18.14); western: 18.62% (95% CI: 14.95-22.94); Ptrend<0.001). Moreover, the incidence of major CVD was consistently higher in rural areas compared with urban areas across eastern ( P<0.001), central ( P=0.01) and western ( P<0.001)_regions, respectively. The 1-year case fatality rate in rural areas was also significantly higher compared with that in urban areas in both eastern ( P<0.001) and western regions ( P=0.02). Conclusions:The incidence and case fatality rate of CVD were high among middle-aged population in China, especially those in western regions with low socioeconomic levels and in rural areas.

Methods:A total of 142 patients with cerebral infarction who were treated in Xing An Meng Hospital from April 2020 to May 2021 were included in this study. They were randomly divided into a control group ( n = 71, intravenous thrombolysis) and a Xingnaojing injection group ( n = 71, intravenous thrombolysis + Xingnaojing injection). Intracranial arterial hemodynamic indexes, National Institutes of Health Stroke Scale score, Fugl-Meyer Assessment Scale score, serum inflammatory factors, oxidative stress indexes, brain injury markers, and the incidence of adverse reactions were compared between the two groups. Results:After treatment, serum levels of interleukin-1β, interleukin-6, and tumor necrosis factor-α were significantly lower in the Xingnaojing injection group than the control group [interleukin-1β: (4.05 ± 0.83) ng/L vs. (6.85 ± 1.02) ng/L, interleukin-6: (43.61 ± 5.14) ng/L vs. (60.31 ± 7.04) ng/L, tumor necrosis factor-α: (35.93 ± 4.25) ng/L vs. (20.93 ± 3.11) ng/L, t = 17.94, 16.14, 15.37, all P < 0.001]. After treatment, the mean blood flow velocities of the anterior cerebral artery, middle cerebral artery, and posterior cerebral artery in the Xingnaojing injection group were significantly higher than those in the control group [anterior cerebral artery: (49.36 ± 5.28) cm/s vs. (41.15 ± 5.12) cm/s, middle cerebral artery: (61.27 ± 7.02) cm/s vs. (50.19 ± 6.08) cm/s, posterior cerebral artery: (44.92 ± 5.63) cm/s vs. (37.26 ± 4.93) cm/s, t = 9.40, 10.05, 8.62, all P < 0.001]. After treatment, the National Institutes of Health Stroke Scale score and Fugl-Meyer Assessment Scale score in the Xingnaojing injection group were superior to those in the control group [National Institutes of Health Stroke Scale score: (10.36 ± 1.52) points vs. (14.62 ± 2.05) points, Fugl-Meyer Assessment Scale score: (76.19 ± 8.08) points vs. (65.28 ± 7.14) points, t = 14.06, 8.52, both P < 0.05]. After treatment, the serum level of malondialdehyde in the Xingnaojing injection group was significantly higher than that in the control group [(6.35 ± 1.02) μmol/L vs. (10.05 ± 1.63) μmol/L), t = 16.21, P < 0.001]. The serum level of superoxide dismutase in the Xingnaojing injection group was significantly lower than that in the control group [(114.31 ± 13.69) U/L vs. (92.25 ± 10.16) U/L), t = 10.90, P < 0.001]. Serum levels of neuron-specific enolase and S100β in the Xingnaojing injection group were significantly lower than those in the control group [neuron-specific enolase: (24.01 ± 3.24) IU/L vs. (30.31 ± 4.02) IU/L, S100β: (0.73 ± 0.17) ng/L vs. (1.13 ± 0.22) ng/L, t = 10.28, 12.12, both P < 0.001). There was a significant difference in the incidence of adverse reactions between the two groups ( P > 0.05). Conclusion:Intravenous thrombolysis combined with Xingnaojing injection for the treatment of cerebral infarction can improve intracranial hemodynamics, reduce the inflammatory response and oxidative stress, and alleviate brain tissue injury. The combined therapy is beneficial to protect the neurological function of patients with cerebral infarction and is highly safe.

Conclusion The BBR-NE can provide a new dosage form for the clinical use of berberine.

Objective:To explore the application effect of new whole-course closed sputum specimen collection technology in intensive care unit patients.Methods:From April 2020 to January 2022, the convenient sampling was used to select 442 ICU mechanical ventilation patients admitted to 6 hospitals in Jiaxing City as the research objects. According to the order of admission time, the patients were divided into the control group ( n=221) and the experimental group ( n=221) . The control group adopted the traditional open sputum specimen collection technology, while the experimental group adopted the new whole-course closed sputum specimen collection technology. The heart rate, the incidence of hypooxygen saturation and the incidence of sputum spatter were compared between the two groups after sputum sample sampling. Results:The incidences of hypooxygen saturation and sputum spatter in the experimental group were lower than those in the control group, and the differences were statistically significant ( P<0.01) . Conclusions:The new whole-course closed sputum specimen collection technology can effectively stabilize the oxygen saturation of ICU patients in the process of sputum specimen collection, reduce the incidence of sputum spatter and promote the safety of both patients and medical staff, which is worthy of clinical promotion and application.

Objective:To explore the clinical efficacy of morcellator assisted by transurethral bipolar plasmakinetic enucleation and resction of the prostate in the treatment of benign prostatic hyperplasia.Methods:A total of 90 patients with benign prostatic hyperplasia treated in the Department of Urology, Shenyang Fifth People′s Hospital from Apirl 2020 to Apirl 2021 were retrospectively analyzed. They were divided into the experimental group ( n=50) and the control group ( n=40) according to different sugical methods.

Objective:To investigate the characteristics of consonant among children with speech sound disorder (SSD) and to provide an empirical basis for the subsequent clinical evaluation and evidence-based intervention.Methods:In this retrospective research a total of 1 395 children diagnosed with SSD from the Language-Speech Clinic of the Department of Children Health Care, Children′s Hospital, Capital Institute of Pediatrics from January 2007 to December 2018 were enrolled and underwent the phonological examination on the lexical level with picture naming, according to phoneme development in Chinese mandarin. The Chi-square trend test was applied to analyze the differences and trends of the proportion of consonant error subtypes in children of different age groups. The Chi-square test was conducted to compare the proportion of consonant error subtypes in different gender.Results:The 1 395 children diagnosed with SSD included 1 044 boys and 351 girls, with an age of (5.1±0.8) years. The occurrence of consonant errors in different locations of articulation was the highest for blade-alveolar /l/ (71.8%, 1 002/1 395) and the lowest for labial/b/(9.3%, 130/1 395). The occurrence of consonant errors of labial/p/f/, supra-dental/z/c/s/, blade-alveolar/t/l/, blade-palatal/ch/r/, velar/k/h/, and lingua-palatal/q/decreased with age (all P<0.05). The occurrence of consonant errors of labial/b/m/, supra-dental/z/c/, blade-alveolar/n/l/, blade-palatal/sh/, velar/h/, and lingua-palatal/x/were higher in boys than those in girls (10.3% (108/1 044) vs. 6.3% (22/351), 11.4% (119/1 044) vs. 6.0% (21/351), 64.8% (676/1 044) vs. 51.9% (182/351), 67.8% (708/1 044) vs. 59.8% (210/351), 16.7% (174/1 044) vs. 8.8% (31/351), 73.7% (769/1 044) vs. 66.1% (232/351), 58.0% (606/1 044) vs. 47.6% (167/351), 24.0% (251/1 044) vs. 14.2% (50/351), and 39.9% (417/1 044) vs. 27.6% (97/351); χ2 =5.167, 8.533, 16.889, 7.447, 12.863, 7.412, 11.650, 14.900, and 17.099, all P<0.05). The error types of consonant were substitution, omission, and distortion. Omission was the main error type of blade-alveolar/l/(53.3%, 743/1 395), distortion was the main error type of velar/h/(11.8%, 165/1 395), and substitution was the main error type of all other consonants. Substitution with blade-palatal/ch/having the highest occurrence of error (60.2%, 840/1 395). Conclusions:The occurrence of the blade-alveolar/l/error is the highest in children with SSD, with boys demonstrating more serious articulation problems. The main error type of consonant is substitution, with blade-palatal/ch/having the highest occurrence of error. These results suggest the necessity of attending to preschoolers′ articulation development. Phonological training targeting blade-alveolar/l/and blade-palatal/ch/should be carried out as early as possible.

Objective:To investigate the time and characteristics of screen exposure, to analyze the risk factors affecting screen exposure in children aged 3 years and younger, and to provide scientific basis for the intervention of screen exposure in children.Methods:The data were collected by convenience sampling from 317 children for routine examination aged 0-36 months who visited the Department of Child Healthcare, Children′s Hospital, Capital Institute of Pediatrics from December 2019 to December 2020. Self-designed questionnaires of the screen exposure were completed by the parents. The basic information, home nurture environment and screen exposure conditions were investigated. Children <18 months of age who used electronic devices and 18-36 months of age who spent more than 1 h/d on electronic devices were defined as with screen exposure. The differences between <18 and 18-36 months of age were compared by rank sum test. Chi-square test and multivariate Logistic regression were used to analyze the association between screen exposure and potential influential factors.Results:Among 317 children, 209 were boys and 108 girls, aged (28±10) months. There were 117 patients aged <18 months and 200 patients aged 18-36 months. Screen exposure time was 0.3 (0, 1.0) h/d and 1.2 (0.6, 2.0) h/d in children aged <18 months and aged 18-36 months, respectively ( Z=-6.770, P<0.01). The proportion of screen exposure was 25.6% (30/117) and 49.0% (98/200) in two age groups, respectively. Logistic regression analysis disclosed that not being the first child ( OR=3.81, 95% CI: 1.13-12.77, P=0.030), caregivers spending >1 h/d on electronic devices in front of their children ( OR=7.39, 95% CI: 2.24-24.46, P=0.001), caregivers believing that screen exposure can promote early childhood development ( OR=4.14, 95% CI: 1.26-13.52, P=0.019) were risk factors for children′s screen exposure in <18 months of age. Caregivers spending >1 h/d on electronic devices in front of their children ( OR=3.29, 95% CI: 1.78-6.08, P<0.01) was risk factor for children′s screen exposure in 18-36 months of age. Mothers with bachelor′s or higher degree ( OR=0.19, 95% CI: 0.05-0.66, P=0.009; OR=0.35, 95% CI: 0.19-0.66, P=0.001), no television in living room ( OR=0.11, 95% CI: 0.03-0.42, P=0.001; OR=0.45, 95% CI: 0.21-0.98, P=0.045) were protective factors for children′s screen exposure in children <18 months and 18-36 months of age. Conclusions:Excessive screen exposure is common among children aged 3 years and younger. The exposure time increases with age, and is affected by several factors.

Objective:To explore the effect of O2O model on young and middle-aged lymphoma patients undergoing chemotherapy.Methods:From February to December in 2019, 68 newly diagnosed lymphoma patients who were hospitalized in the lymphoma ward of our hospital were selected as the research object, and divided into intervention group (32 cases) and control group according to the order of admission (36 cases), the intervention group was used O2O model, and the control group was used general care combined with symptom diary, after 6 cycles′ intervention time, We compare the effects of the two groups of patients by using self-management scale and quality of life assessment scale.Results:Comparison of self-management ability: after intervention, the patients in the intervention group scored in the six dimensions of total self-management, daily life management, symptom management, psychological management, communication with medical staff, information management and self-efficacy, respectively(4.37±0.31), (4.05±0.47), (4.45±0.54), (4.10±0.45), (4.30±0.49), (3.88±0.59), (4.73±0.34) points, the control group were (3.92±0.43), (3.75±0.61), (3.55±0.69), (3.75±0.66), (3.58±0.86), (3.26±0.80), (4.40±0.74) points, the difference between the two groups was statistically significant ( t value was 2.263-5.944, P <0.05). Comparison of quality of life: after intervention, the scores of the patients in the intervention group in the two dimensions of total quality of life, physical condition and condition were (68.52±9.02), (16.97±2.31), (15.13±2.60) points, the control group were (64.06±6.84), (14.81±2.04), (13.97±1.99) points, the difference between the two groups was statistically significant ( t value was 2.337, 4.101, 2.065, P<0.05).

This article reported a case of malignant pheochromocytoma and paraganglioma with cranial metastasis. The patient was a 25-year-old man. At the age of 10, he was diagnosed with retroperitoneal paraganglioma. He received radiotherapy after partial resection of the tumor. At the age of 15, when he consulted for headache and hypertension, a space occupying lesion was found on the right adrenal without further diagnosis and treatment. His headache and hypertension were aggravated at the age of 25. Then he visited our medical center and diagnosed with right adrenal pheochromocytoma. He undertook an operation to remove the right adrenal lesion, and his blood pressured could be controlled in the normal range with oral antihypertensive medication. One year after the surgery, a cranial lesion with positive 131I-metaiodobenzylguanidine imaging was found following the increase of norepinephrine and dopamine in both blood and urine. The diagnosis of malignant pheochromocytoma with cranial metastasis was confirmed. The cranial lesion was treated with cyberknife therapy for 4 times, and the lesion was slightly reduced. Four year after the removal of right adrenal tumor, he developed multiple bone metastasis in the right ribs and left ilium, and then he received 131I-metaiodobenzylguanidine radiotherapy. Additionally, the results of gene test indicated a pathogenic mutation of SDHB. During the follow-up period of one year after the treatment, his blood pressure fluctuated to about 140/90mmHg with 10mg of phenoxybenzamine once a day. The case is a malignant pheochromocytoma with multiple bone metastasis characterized by a long course with an ideal prognosis in a way. Consequently, we suggested the diagnostic pathway with genetic testing based on clinical phenotype to approach more timely diagnosis and reasonable evaluation of the prognosis in pheochromocytoma and paraganglioma. Furthermore, clinicians should pay more attention to the long-term surveillance.

Objective:To investigate the features and trends of functional speech sound disorder and related erroneous consonants in children, so as to provide evidence for clinical evaluation and rational intervention.Methods:Clinical data of 1 562 children diagnosed with functional speech sound disorder in the language-speech clinic of the Department of Child Health Care, Children′s Hospital, Capital Institute of Pediatrics from January 2007 to December 2018 were analyzed retrospectively. By using the mandarin phonetic test table, the picture-naming method was adopted to test the word-level pronunciation. The Chi-square test was conducted to analyze the incidence of consonant errors in different age groups, gender and different places of articulation. The trend in incidence of the consonant errors in different age groups and during the last 12 years were analyzed by chi-square trend test. Results:A total of 1 562 cases were diagnosed with functional speech sound disorder, including 1 171 males and 391 females, the age was 4-17 years. The incidence of consonant errors in different places of articulation was 43.0% (672/1 562) for labial, 47.0% (734/1 562) for lingua-palatal, 63.7% (995/1 562) for velar, 77.7% (1 213/1 562) for linguo-alveolar, 78.9% (1 233/1 562) for apico-dental and 81.6% (1 274/1 562) for palatal. The incidence of consonant errors in males on labial, lingua-palatal, linguo-alveolar and palatal was higher than that in females (44.7% (523/1 171) vs. 38.1% (149/391), 49.1% (575/1 171) vs.40.7% (159/391), 80.1% (938/1 171) vs.70.3% (275/391), 82.8% (970/1 171) vs.77.7% (304/391), χ2 =5.138, 8.379, 16.126 and 5.042,all P<0.05). The incidence of consonant errors on labial, lingua-palatal, velar, linguo-alveolar, apico-dental and palatal decreased with age (χ2 =27.023, 13.230, 20.579, 29.718, 26.390, and 17.887, all P<0.01). The incidence of consonant errors on labial, linguo-alveolar, apico-dental increased with years (χ2 =9.030, 51.894 and 18.507, all P<0.01). Conclusions:The incidence of palatal errors is the highest in children with functional speech sound disorder. As part of the palatal errors could not be completely self-healing with growing, the phonological therapy for palatal errors should be carried out as early as possible. The incidence of consonant errors on labial, linguo-alveolar, and apico-dental presents an upward tendency with years, more attention should be paid to the factors related to the acquisition of these consonants.
