Objective:To analyze the ultrasonic features of tonsillar lymphoma to improve the diagnostic accuracy.Methods:The clinical, pathological and ultrasonic data of nine patients with tonsillar lymphoma confirmed by pathology at Tianjin Medical University Cancer Institute and Hospital during June 2015 and June 2022 were analyzed retrospectively, and the characteristics of their ultrasonic images were summarized.Results:All 9 cases of tonsil lymphoma were unilateral tonsil disease, including 4 cases on the left side and 5 cases on the right side. The average maximum diameter of tonsil lymphoma in 9 cases was 4.32 cm. There were 3 cases with simultaneous involvement of tonsil and cervical lymph nodes, all of which were ipsilateral lymph nodes. Gray scale ultrasound showed that the lesions were hypoechoic, with clear boundaries in 7 cases and unclear boundaries in 2 cases. The shape was full and irregular in 5 cases and oval in 4 cases. The echo was uniform in 7 cases and uneven in 2 cases. Color Doppler ultrasonography showed abundant internal blood flow signal in 1 case, a little dotted linear internal blood flow signal in 5 cases, and no obvious internal blood flow signal in 3 cases.Conclusions:The ultrasonic features of tonsillar lymphoma include hypoechoic area, clear boundary, full shape, irregular and uniform internal echo, no or low linear signal of internal blood flow. Ultrasonography is of great value in the diagnosis of this disease and can help clinical decision-making.

Objective To observe the effects of intravenous or inhalation anesthesia on perioperative re-spiratory system adverse events(PRAE)in children after extubation.Methods A total of 100 children pa-tients with elective tonsillectomy or adenoidectomy under general anesthesia endotracheal intubation in this hospital from July to December 2023 were selected as the study subjects and divided into the intravenous anes-thesia group and inhalation anesthesia group according to the random number table method,50 cases in each group.The intravenous anesthesia group used propofol for venous induction and maintenance,while the inha-lation anesthesia group used sevoflurane inhalation for induction and maintenance.The incidence rate of PRAE after extubation,anesthetic maintenance stage quality,incidence rates of postoperative nausea,vomiting and agitation were recorded in both groups.Results Compared with the inspiration anesthesia group,the PRAE incidence rate(16.0％vs.42.0％),hypoxia incidence rate(14.0％vs.38.0％)and pediatric anaesthesia e-mergence delirium(PAED)score[5(2,8)points vs.6(4,11)points]in the venous anesthesia group were low-er,the extubation time was longer[(19.6±10.6)min vs.(14.9±8.9)min],postanesthesia care unit(PACU)stay time was shorter[(25.4±5.2)min vs.(27.9±6.4)min],the differences were statistically significant(P＜0.05).The proportions of intubation time,intubation times＞once and the swallow and limb activity dur-ing anesthetic maintenance had no statistical difference between the two groups(P＞0.05).The heart rate had no statistical difference among 4 time points of before and after induction,after intubation and after extu-bation(P＞0.05).Compared with before induction,the heart rate after extubation was significantly increased,and the difference was statistically significant(P＜0.05).Conclusion The incidence rate of PARE in pediatric ve-nous anesthesia is lower.

Objective:To analyze the implementation of early essential newborn care (EENC) in baby-friendly hospitals in China.Methods:This is an investigation carried out using convenience sampling method. People in charge of labor ward, obstetric wards or neonatology department of the selected hospitals, such as baby-friendly hospitals with birth facilities, primary or higher level of hospitals, or general hospitals or those specialized in obstetrics and gynecology or materal and child health care centers, were selected as the subjects of the survey. Information about EENC practices in these hospitals was collected using a self-designed questionnaire sent through WeChat from April 1 to 30, 2021. Chi-square test was used for statistical analysis. Results:A total of 126 questionnaires were distributed and 124 (124 baby-friendly hospitals) were withdrawn. There were 74 hospitals in the eastern, 18 in the central and 32 in the western region. Among the 124 hospitals, tertiary hospitals, general hospitals, and maternity and child care hospitals accounted for 72.6% ( n=90), 64.5% ( n=80) and 35.5% ( n=44), respectively. There were no significant differences in the hospital type, levels, EENC coverage and training, or implementation of mainly recommended EENC practices among the hospitals in the eastern, central and western regions (all P>0.05). The implementation rate of at least one mainly recommended EENC practice was 79.0% (98/124) and there was no significant difference in the implementation rates among eastern, central and western regions [86.4% (64/74), 13/18 and 65.6% (21/32), χ2=6.60, P=0.159]. A total of 80 (64.5%) hospitals implemented 10 or more recommended EENC practices, and the implementation rates in eastern, central and western regions were 71.6% (53/74), 10/18 and 53.1% (17/32), respectively ( χ2=4.08, P=0.130). Among the 17 mainly recommended measures of EENC, in eastern, central and western hospitals, the implementation rates were 10.8% (8/74), 2/18 and 18.8% (6/32) for mother-infant skin-to-skin contact for 90 min after birth; 66.2% (49/74), 11/18 and 68.8% (22/32) for delayed umbilical cord clamping; and 25.7% (19/74), 7/18 and 21.9% (7/32) for delayed routine care following skin-to-skin contact, respectively ( χ2=6.57, 0.34 and 4.53, all P>0.05). Conclusions:There is a big gap between the implementation of EENC in most baby-friendly hospitals in eastern, central and western China and the recommendation of the World Health Organization. It is necessary to further strengthen and standardize the implementation of EENC practices in baby-friendly hospitals in our country to continuously improve the health of newborns.

Objective:To analyze the detection strategy and basic detection situation of markers of infectious diseases transmitted by transfusion in blood testing laboratories of blood stations in China.Methods:Based on the data of practice comparison working party of Blood Stations in Mainland of China from 2017 to 2021, the data on the testing strategies and the basic detection information of the markers for the transmission of infectious diseases through transfusion in the member laboratories of the practice comparison working party of Blood Stations in Mainland of China from 2017 to 2021 were collected, and the situation of the selection for testing markers, testing strategy and the testing method and other relevant aspects were sorted out and analyzed by charts.Results:The selection of the testing markers was consistent, but HTLV testing item was added in some member laboratories. The detection strategy of using two ELISA reagents and one nucleic acid testing (NAT) reagent simultaneously was adopted in 47 member blood stations; 3) NAT method was dominated by mini pool-NAT in member laboratories. The number of members adopting mini-pools of 8 (MP8)-NAT decreased from 17 in 2017 to 14 in 2021, while the number of members adopting mini-pools of 6 (MP6)-NAT increased from 13 in 2017 to 22 in 2021; Roche NAT system accounted for the largest proportion.Conclusions:In order to ensure blood safety and avoid missing detection, the blood stations still adopt the detection strategy of using two ELISA reagents and one nucleic acid testing (NAT) reagent simultaneously; Meanwhile, in order to increase the NAT positive rate, the proportion of mini pool-NAT mainly decreased year by year despite its dominating role, while the proportion of individual donation-NAT increased year by year; NAT method is transiting from mini-pools of 8 (MP8) to mini-pools of 6 (MP6); The proportion of imported NAT system used in NAT laboratory is relatively large.

Objective:To analyze the clinical characteristics of hospitalized patients with distal deep venous thrombosis (DDVT).Methods:Medical records of patients without DDVT at admission and discharged from January 1,2021 to June 30,2021, were retrospectively reviewed. During the pre-hospitalization and hospitalization period the ultrasonography was performed for detection of DDVT. The venous thromboembolism (VTE) risk scores were evaluated with Caprini scale for surgical patients, and evaluated with Padua scalefor nonsurgical patients.Results:A total of 16 400 patients, 8 827 males and 7 573 females with a mean age of (63.8±14.2) years (14 to 101 years) were enrolled, among whom DDVT occurred in 1 193 patients (DDVT group), including 73 cases developed during pre-hospitalization; meanwhile 124 patients were diagnosed as deep vein thrombosis(DVT), and 15 083 patients without DVT served as non-DDVT group. The detection rate of DDVT in patients with medium/high VTE risk scorewas significantly higher than thatin low-risk patients [12.8% (982/7 644) vs. 2.4% (211/8 756), χ2=659.10, P<0.001]. The detection rate of DDVT for medium/high VTE risk score group was the highest in emergency intensive care unite and intensive care unite(ICU; 34.3%, 68/198), followed by that in departments of rehabilitation (25.7%, 45/175), neurology (19.9%,37/186), neurosurgery(19.4%,83/428), respiratory medicine(19.0%,56/295) and orthopedics (15.4%, 378/2 451).The detection rate of DDVT increased with age.The lowest detection rate was found in the age group 14 to 40 years, for low VTE risk score group it was 0.5%(4/770), for the medium/high VTE risk score group it was 3.0%(11/362, χ2=10.10, P<0.001).In patients over 75 years of age, the detection rate of DDVT was 5.2%(85/1 624) in low VTE risk score group, and 18.0%(389/2 158) in medium/high VTE risk score(χ2=138.82, P<0.001).The mean age of the DDVT group was older than that of non-DDVT group [(71.0±12.1) vs. (63.2±14.2) years, t=21.14, P<0.001]. The abnormality rate of D-dimer level in DDVT patients was significantly higher than that in non-DDVT patients [71.4%(813/1 138) vs. 25.4%(3 492/13 770), χ2=1 086.80, P<0.001]. The median length of hospital stay was significantly longer than that of the non-DDVT group [11.0 (8.0, 19.0) vs. 6.0 (4.0, 10.0)d, Z=-26.67, P<0.001].The risk factors for non-surgical DDVT patients were age, bed rest for ≥3 d, and acute infection; while the risk factors for surgical DDVT patients were age, fracture in hip, pelvis or lower limb, bedridden for ≥3 d and body mass index (BMI)>25 (kg/m 2). Conclusion:The detection rate of DDVT is higher in hospitalized patients, especially for those in ICU and rehabilitation department, and those over 75 years old with high VTE score. Advanced age, fracture or immobilization, and long-term bed rest are the main risk factors for DDVT.

Objective:To explore the clinical significance of serum Chromogranin A (CGA) level in predicting the prognosis of children with severe hand, foot, and mouth disease (HFMD) and complicating neurogenic pulmonary edema (NPE).Methods:A total of 162 patients with HFMD admitted in our hospital from January 2017 to December 2019 were enrolled in the study; and 40 age-matched healthy children were selected as controls. According to the disease severity and complication the patients were divided into three groups: mild group ( n=88), severe without NPE group ( n=46) and severe with NPE group ( n=28). In 72 severe HFMD patients 16 cases died (fatal group) and 56 cases survived (survival group) within 28 days of hospitalization. The serum CGA, LAC, GLU, WBC, PCT, IL-6, cTnT were measured in all subjects. SPSS 23.0 software was used for data analysis, and the receiver operating characteristic (ROC) curve was used to evaluate the various indicators for predicting the prognosis of severe HFMD combined with NPE. Results:The serum CGA, GLU, LAC, IL-6 and cTnT levels in severe HFMD group with NPE significantly higher than those in the other three group ( H=61.554, 79.031, 86.994, 36.477, 75.021, all P<0.05 ). The serum CGA, LAC, GLU and IL-6 levels in the fatal group were significantly higher than those in survival group ( Z=-6.094, -4.621, -4.283, -5.504, all P<0.05). There was no significant difference in the levels of WBC, PCT and cTnT between the survival group and the fatal group ( P>0.05). The area under the receiver operating curve (AUC) of serum CGA was 0.890 (95% CI: 0.833-0.947) for predicting the prognosis of patients and the best cut-off value was 120.59 μg/L. Conclusion:The detection of serum CGA levels may be beneficial for the early diagnosis of severe HFMD with NPE, and can be used as one of the predictors of death from severe HFMD.

Clinical features of and genetic mutations in two cases of pseudohypoparathyroidism type Ⅰ a(PHP Ⅰ a) with early-onset skin nodules were analyzed.Both of the two patients were males,and their ages at onset were 2 and 3 months respectively.They both presented with early-onset skin nodules as the main clinical manifestation,and were clinically characterized by a round face,short neck and early obesity.Histopathological examination of skin lesions showed subcutaneous ectopic osteogenesis in both patients.The first patient had low blood calcium,high blood phosphorus,high parathyroid hormone (PTH),and gene sequencing showed a heterozygous mutation c.399delT causing a T base deletion at position 399 in exon 5 of the GNAS gene.The second patient had normal blood calcium and phosphorus levels as well as normal PTH levels at early stage,and gene sequencing showed a heterozygous mutation c.939delT causing a T base deletion at position 939 in exon 9 of the GNAS gene.The blood PTH level was found to increase in the second patient after 1-year follow-up.Both the patients were confirmedly diagnosed with PHP Ⅰa.After treatment with vitamin D3,no new skin nodules occurred,and the blood calcium and phosphorus levels returned to normal.

Objective: Attentional biases toward emotional scenes may represent vulnerability and maintenance factors in depression. Antidepressant therapy may improve cognitive function and reduce depression, and is considered as the mechanism of action of antidepressants. Therefore, we conducted an eye-tracking test to examine whether selective serotonin re-uptake inhibitor (SSRI) antidepressants can reduce negative attentional biases and elicit clinical responses in depression. Methods: Twenty first-episode depressive patients freely viewed three types of pictures that depicted different emotional scenes (i.e., positive-control, neutral-control, and negative-control) for 4,000 ms while their eye movements were monitored. The attentional bias to different emotional scenes was assessed before and after eight weeks of SSRI treatment using the eye-tracking method. The control group included a group of healthy individuals. Results: The results revealed that first-episode depressive patients oriented their gaze more frequently to negative images and less to happy images, compared to controls. Importantly, the attentional bias in depressive patients was regulated after eight weeks of SSRI treatment. Patients showed an increased tendency to fixate on positive images and a decreased tendency to focus on negative images. Conclusion This suggests that SSRI antidepressants decrease vulnerability to negative images, while having an effect on attention in respect to positive images.

Objective To explore the protective effect of magnesium sulfate on the nerve injury in severe hand, foot and mouth disease ( HFMD) caused by enterovirus A71 ( EV-A71) and to investigate its clinical and prognostic effects.Methods A total of 240 cases of severe HFMD with EV-A71 infection and nerve injury were enrolled.According to the random number table method, the patients were randomly divided into conventional treatment group (control group) and magnesium sulfate treatment group ( treatment group), with 120 cases in each group.The control group was given the routine treatment, and the treatment group was given the magnesium sulfate adjuvant treatment on the basis of routine treatment.The neurological symptoms and signs, clinical efficacy and prognosis were observed before and after treatment in the two groups.The blood and cerebrospinal fluid neuron-specific enolase ( NSE), S100-βprotein and neuropeptide Y ( NPY) were analyzed before and after treatment.The amplitude integrated electroencephalogram (aEEG) was used to monitor the abnormal recovery of EEG.The t-test was applied to analyze quantitative data, and the chi-square test was used for qualitative data comparison.Results Among children with severe HFMD, there were 83 cured cases, 29 improved cases and 8 ineffective cases in control group, with the total effective rate of 93.3%; while in the treatment group, 101 cases were cured, 18 cases were improved and 1 case was ineffective, the total effective rate was 99.2%.The therapeutic effects (Z＝2.918, P＝0.004) and the total effective rate ( χ2 ＝4.156, P＝0.041) were statistically significantly different between the two groups.Three days after treatment, the average levels of serum NSE, S100-βprotein and NPY in magnesium sulfate treatment group were significantly lower than those in control group (t＝-7.239,-10.020 and -11.053, respectively, all P＜0.01).Five days after treatment, the average levels of cerebrospinal fluid NSE, S100-β protein and NPY in magnesium sulfate treatment group were significantly lower than those in control group ( t＝-6.546,-13.308 and -10.258, respectively , all P＜0.01).After treatment, the neurological function score in treatment group was significantly lower than that in control group and that before treatment , and the differences were statistically significant ( t ＝-9.473 and 12.162, respectively, both P ＜0.01 ).The recovery time of the main symptoms and signs in treatment group was ( 2.33 ±0.76 ) d, which was significantly shorter than that of control group ([3.21 ±0.82] d), the difference was statistically significant (t＝-12.52, P＜0.05).The average length of hospital stay in treatment group was (5.79 ±1.42) d, which was shorter than that in control group ([ 6.71 ±1.46 ] d ), and the difference was statistically significant ( t＝-4.932, P＜0.05).Of the 240 children with severe HFMD, 194 (80.8%) patients had abnormal aEEG.Before treatment, the aEEG abnormal rates in control group and the magnesium sulfate treatment group were 79.2%(95 cases) and 82.5%(99 cases), respectively, there was no significant difference ( χ2 ＝0.430, P＞0.05); while after treatment for 3 days, 76 cases in treatment group returned to normal, and the recovery rate of aEEG was 76.8%, which was higher than that in control group (52.6%). The difference was statistically significant ( χ2 ＝12.406, P ＜0.05 ).Conclusions Magnesium sulfate adjuvant therapy can reduce the abnormal levels of NSE, S100-βand NPY in blood and cerebrospinal fluid, relieve clinical symptoms, shorten the course of disease and average length of hospital stay, improve the neurological function score, and promote the recovery of abnormal aEEG.Thus, it has neuroprotective effect on severe HFMD with nervous system lesion.
