Objective To investigate the prognostic factors of life and functional outcome of the first hemiparetic stroke patients. Methods One hundred and eighteen stroke subjects were registered prospectively. The Barthel index (BI) , Rankin scale (RS) , Mortricity index(MI) , Mini-mental state examination (MMSE) , Montgomery-Asberg depression scale (MADRS) and a scale of general state and risk factors were used to evaluate at the 48th hour, the 15th day and the 90th day after stroke. Results The patients' performance, as demonstrated by their scores with all the evaluation instruments, changed significantly at all the time points of evaluation after stroke (P ＜0.05). There was no significant difference between the performance at the 48th hour and the 15th day after stroke ( P ＞ 0.05 ). But at the 90th day after stroke, the activity of daily living performance and the depression status recovered significantly (P ＜ 0.01 ). Logistic regression analysis showed that, such factors as pneumonia, urinary incontinence within 48th hour and deep sensation disturbance might adversely influence patients' activity of daily living performance at the 90th day after stroke; the muscle strength of upper extremities at the 48th hour, and MMSE scores at the 15th day after stroke acted as the protective factors. Conclusions The stroke patients improved significantly with regard to their clinical and functional manifestations when evaluated 90 days after stroke onset. The main factors influencing the activity of daily living performance 90 days after stroke onset included deep sensation disturbance,pneumonia, urinary incontinence and muscles strength of upper extremities at 48th hour, and MMSE scores at the 15th days after onset.

OBJECTIVETo study whether co-stimulatory molecule CD40 of alveolar macrophage (AM) participated in the occurrence and development of silicosis, and to explore the intervention of Yiqi Huoxue Decoction (YHD) in the fibrosis of silicosis patients.

METHODSTotally 46 silicosis inpatients and outpatients were recruited and randomly assigned to the Western treatment group (A) and the Chinese medicine (CM) treatment group (B), 23 in each group. Patients in Group A received routine symptomatic treatment such as anti-inflammation, phlegm resolving, anti-spasm, and asthma relief, and so on. Patients in Group B additionally took YHD, one dose daily for 14 successive days. Besides, another 18 patients with chronic cough and sense of laryngeal foreign bodies were recruited as the normal control group, who had no obvious lesion confirmed by bronchofi6roscope and clinical diagnosis of the lung. They were treated by symptomatic supporting treatment. The alveolar lavage fluid was collected from all patients and isolated, and AM cells were cultured. The level of CD40 mRNA was detected by RT-PCR. The expression of CD40 protein was detected by Western blot.

RESULTSCompared with the normal control group, expression levels of CD40 mRNA and CD40 protein significantly increased in Group A (P < 0.01). Compared with Group A, expression levels of CD40 mRNA and CD40 protein significantly decreased in Group B (P < 0.01).

CONCLUSIONSHighly expressed co-stimulatory molecule CD40 of AM might participate in pulmonary fibrosis. YHD could hinder its roles, inhibit the progression of fibrosis, thereby playing an interventional role of treatment.

Objective: To investigate the prevalence of hypertension among primary and middle school students living in Suzhou City, Jiangsu Province, so as to provide insights into comprehensive hypertension control among children and adolescents. Methods: Primary and middle school students at ages of 7 to 17 years were recruited for a questionnaire survey in Suzhou City using the stratified cluster random sampling method from September to December, 2020, and the height and body weight were measured. Blood pressure was measured at three separate clinic visits according to the national criteria Reference of Screening for Elevated Blood Pressure among Children and Adolescents Aged 7-18 Years ( WS/T 610-2018 ), and the detection of elevated blood pressure was estimated at three separate visits. In addition, factors affecting elevated blood pressure were identified. Results: A total of 3 713 students were enrolled, including 1 924 boys ( 51.82% ) and 1 789 girls ( 48.18% ). The detection of elevated blood pressure was 13.63%, 5.36%, and 3.37% at three separate visits, respectively, and the prevalence of hypertension ( elevated blood pressure at all three visits ) was 3.37%. The detection rates of elevated blood pressure were all higher at three visits ( 16.90%, 8.40%, and 5.26% ) among students at ages of 12 to 17 years than among students at ages of 7 to 11 years ( 9.65%, 1.67%, and 1.07%, P<0.05 ). The detection of elevated blood pressure was significantly higher in boys ( 15.23% ) than in girls (11.91%) at the first visit ( P<0.05 ), while no significant differences were seen at the second or third visit ( P>0.05 ). In addition, higher detection rates of elevated blood pressure were seen in obese ( 27.62%, 11.51%, and 7.06% ) and overweight students ( 17.45%, 6.95%, and 4.85% ) than in students with normal weight ( 9.44%, 3.54%, and 2.15% ) at all three visits, and greater detection rates of elevated blood pressure were found in obese students than in overweight students at the first and second visits ( P<0.017 ). Conclusions The prevalence of hypertension was 3.37% based on three separate visits among primary and middle school students in Suzhou City. Measurement of blood pressure at three separate visits within different days is effective to reduce the false positive rate of hypertension and decrease misdiagnosis among children and adolescents.

[Summary] Sixty-one patients suffering from pituitary apoplexy( PA) were mainly diagnosed according to pathologic findings, and were collected from case record, pathology, and MRI databases. They were classified into 4 types according to the clinical condition: the insidious type was characterized with only positive pathological findings;the asymptomatic type had both positive pathologic and MRI findings; the subacute type had PA associated symptoms longer than 2 weeks; and the acute type had PA associated symptoms for 2 weeks or less. The latter 2 types had positive pathological and MRI findings additionally. The basic lesions, acute or chronic symptoms, endocrinopathies and MRI findings were compared among 4 types. Results showed as followed. In all patients, there were headache(60. 7% ), blurred vision(55. 7% ), vomiting(21. 3% ), and dizziness(14. 8% ). Apoplexy associated symptoms comprised severe headache (24. 6% ), rapid vision loss (29. 5% ), and blepharopotosis or diplopia (9. 83% ). Insidious, asymptomatic, subacute, and acute types were composed of 15 (24. 6% ), 9 (14. 8% ), 19 (31. 1% ), and 18 (29. 5% ) cases, respectively. Aging and intracranial space-occupying symptoms as first complaint showed increasing trend from mild to severe types(both P<0. 05), while in chronic course it showed decreasing trend(P<0. 05). Acute massive symptoms(P<0. 01), and non-functional tumor(P<0. 01) in the 2 clinical types were much more frequent than in the two mild types. Half or more pituitary-target glands showed impaired functions in each type, and the impairment showed increasing trend through mild to severe types(P<0. 01). The present study provided a brief typing system in order to expand PA concept to a wider span covering various conditions. Some differences in tumor composition and endocrinopathies existed among the four types.

OBJECTIVETo study the effect of Wenyang Decoction (WD) on the differentiation of CD34+ progenitor cells of occupational asthma (OA) model rats.

METHODSFifty healthy male SD rats were randomly divided into five groups, i.e., the model group, the blank control group,the WD group,the Western medicine group,the combined group, 10 in each group. Prednisone suspension (10 mg/kg) was administered to rats in the Western medicine group by gastrogavage. WD (20 g/kg) was administered to rats in the WD group by gastrogavage. Prednisone suspension plus WD was administered to rats in the combined group by gastrogavage. Normal saline was administered to rats in the model group and the blank control group by gastrogavage. The general condition of rats was observed. Expression levels of peripheral blood IL-5 and eotaxin, eosinophils (EOS), CD34+, CC chemokine receptor 3 (CCR3+) in bone marrow suspension were detected by ELISA, Wirght-Giemsa, and flow cytometry, respectively.

RESULTSCompared with the blank control group,expression levels of IL-5 and eotaxin in peripheral blood were significantly higher (P < 0.01), and the count of EOS and CD34+ cells, as well as CD34+ /CCR3+ significantly increased (P < 0.01) in the model group. Compared with the model group, expression levels of IL-5 and eotaxin, the count of EOS, CD34+ cells, CD34+ / CCR3+ were lowered in three treated groups (P < 0.01). Compared with the Western medicine group, the count of EOS and CD34+ / CCR3+ decreased in the combined group (P < 0.01). The count of EOS was significantly lower in the combined group than in the WD group (P < 0.01).

CONCLUSIONWD could reduce levels of in vivo inflammatory factors, and restrain the differentiation and recruitment of EOS,thereby alleviating the differentiation of CD34 progenitor cells to EOS.
