Objective To explore the value of procalcitonin (PCT)and interleukin -6 (IL -6)in the early diagnosis and prognostic evaluation of the patients with lumbar intervertebral disc herniation,and their correlation with the course and lumbar function.Methods 100 patients with lumbar disc herniation (study group)and 35 patients with lumbar non -borne diseases (control group)were collected,their preoperative clinical symptoms were scored on the basis of the lumbar scoring system of Japanese Orthopaedic Association (JOA),the enzyme -linked immunosor-bent assay was applied to determining the content changes of PCT and IL -6 of the two groups,and the linear correla-tion analysis was used to explore the relevance of PCT and IL -6 to the course.Results The contents of the PCT and IL -6 in the study group's serum were respectively (25.13 ±0.86)ng/L and (10.26 ±0.36)ng/L,while those in the control group's serum were respectively (223.85 ±0.61)ng/L and (50.11 ±1.23)ng/L,both with statistical sig-nificance (t =2.542,2.206,P <0.01).The IL -6 was positively correlated with the disease duration of the patients with lumbar disc herniation (r =0.32,P =0.000),and negatively correlated with their JOA score (r =-0.45,P =0.003),and the PCT was positively correlated with the patients'disease duration (r =0.35,P =0.001),and nega-tively correlated with their JOA score (r =-0.53,P =0.005).Conclusion The PCT and IL -6 have a certain role in the early diagnosis of lumbar disc herniation,and have some relevance to the course of disease and the lumbar func-tion changes.

Purpose To observe the effect of Rongban Tongmai Granules on thrombosis and blood viscosity of in vitro rat model of blood stasis, and to study the activating blood circulation effect of the drug.Methods To observe the effect of the Rongban Tongmai Granules on thrombosis and blood viscosity of in vitro rat model of stasis, subcutaneous inject rat with epinephrine hydrochloride, and then copy "blood stasis" model by ice water stimulation in rats.Results According to a continuous 7 days′intragastric administration of Rongban Tongmai Granules, thrombus length of blood stasis model rats in vitro reduced significantly (P<0.05-0.01),wet and dry weight of thrombus reduced significantly (P<0.05), the shear rate of the whole blood viscosity under 100 S~(-1), 30 S~(-1), 5 S~(-1) decreased significantly as well (P<0.05-0.01), and the shear rate of whole blood viscosity had decreasing tendency under 200 S~(-1).Conclusion Rongban Tongmai Granules can inhibit thrombosis and lower blood viscosity.

Objective To examine the impact of case management on hospitalizations of the chronically and severely mentally ill patients in Zhongshan. Methods Patients with severe and chronic mental illness,aged ≥ 15 years and living in pilot area were divided into two groups naturally since the program of case management launched, 65 cases in the group of case management and 112 patients in the group of standard management. Hospitalizations of the two groups before and after case management were compared. Results Data were analysised with MIXED procedure. Length of stay in days per admission (LOS) of both groups decreased with time in years (F=11.02, P=0.001), and the decline in LOS of case management group was greater than that of standard management group (F=9.02, P=0.003). The average admissions of case management group was more than that of standard management group (F=4.98,P=0.03). There was no significant differences in average hospitalization incidents before and after case management in both groups(case management group 5.13%vs. 5.38%, standard management group 7.14%vs. 8.92%, P>0.05). Conclusions Case management was effective in reducing hospitalizations for a group of Chinese with chronic and severe mental illness, and may contribute to the balance on mental health resources between community and hospital.

Objective:To analyze the patterns of antibacterial agents in Chinese children surveyed by the China multi-center monitoring network for the application of antibacterial agents in children and neonates in 2019 by using World Health Organization (WHO) Access, Watch, Reserve and Not-recommended (AWaRe) and typical anatomical/therapeutic/chemical (ATC) in this study.Methods:The cross-sectional method was adopted.A multi-center cross-sectional survey was conducted on one day from September to December 2019.The information of all inpatients taking antibiotics was uploaded to the network-based data collection system (https: //garpec-31.mobilemd.cn/login.aspx? relogin=true). This study covered 13 hospitals from 10 provinces and cities in China.All hospitalized children in the Respiratory Department, Infectious Disease Department, General Surgery Department, Pediatric Intensive Care Units, Neonatal Intensive Care Units and Neonatology joined in this survey.The clinically used antibacterial agents were classified by AWaRe and ATC, and the AWaRe and ATC distributions of antibacterial agents prescribed for Chinese children and neonates were described.Results:Of the 2 644 antibiotic prescriptions included from 13 hospitals, 2 134 (80.71%) were for children and 510 (19.29%) were for neonates.Of all antibiotic prescriptions, there were 368 (13.92%) Access antibiotics prescriptions, 1 973 (74.62%) Watch prescriptions, 60 (2.27%) Reserve prescriptions and 243 (9.19%) Not-recommended prescriptions.The top-five antibiotics prescribed for children and neonates were third-generation cephalosporins (1 056, 39.94%), macrolides (492, 18.61%), carbapenems (275, 10.40%), beta lactam-beta lactamase inhibitors (246, 9.30%), and second-generation cephalosporins (136, 5.14%). The use ratios of Access, Watch, Reserve and Not-recommended antibiotics in each center ranged from 0 to 30.00%, 36.67% to 97.20%, 0 to 17.02% and 0 to 33.33%, respectively.In 1 360 antibiotic prescriptions for children and neonates with pneumonia, there were 152 (11.18%) Access antibiotics, 1 051 (77.28%) Watch antibiotics, 37 (2.72%) Reserve antibiotics, and 120 (8.82%) Not-recommended antibiotics.The top-five antibiotics prescribed for children with pneumonia were third-generation cephalosporins (522, 38.38%), macrolides (388, 28.53%), beta lactam-beta lactamase inhibitors (141, 10.37%), carbapenems (117, 8.6%) and penicillins (49, 3.60%).Conclusions:Watch antibiotics and broad spectrum antibiotics such as third-generation cephalosporins and macrolides prone to induce resistance are the main antibacterial agents used in Chinese children and neonates with pneumonia.Broad-spectrum antibiotics may be overused in Chinese children and neonates.

  Objective  To study the demographic and clinical characteristics, correlation of genotype and phenotype and treatment of Blau syndrome to facilitate early diagnosis and timely treatment of Blau syndrome.  Methods  Seventy-two patients with Blau syndrome from 11 centers from May 2006 to April 2022 were retrospectively analyzed, and their general information, clinical data, laboratory examination and treatment medication were collected.  Results  The distribution of patients with Blau syndrome was uniform in geographical north and south of China, and there was no obvious gender bias. The mean age of onset was (14.30±12.81) months, and the age of diagnosis was (55.18±36.22) months. 35% of patients with Blau syndrome happened before 1 year old, and all patients developed before 5 years old. 87.50% (63/72) had granulomatous arthritis, 65.28% (47/72) had rash, 36.11% (26/72) had ocular involvement, 27.78% (20/72) had fever, and 15.28% (11/72) had pulmonary involvement. Arthritic manifestations of Blau syndrome were most at risk, followed by rash, ocular involvement, and fever.The first 25 months of the disease, the risk of developing a rash was the greatest. The risk of developing arthritis was the greatest between 25 months and 84 months. The main mutations were p.R334Q and p.R334W, and patients with p.R334Q mutation had relatively high incidence of fever (35.71%[5/14] vs. 14.29%[1/7], P=0.43) and ocular involvement (42.86%[6/14]vs. 28.57%[2/7], P=0.51). There was a relatively high incidence of rash (85.71%[6/7] vs. 64.29%[9/14], P=0.59) in patients with the p.R334W mutation. Forty-five patients(62.50%)were treated with a combina-tion of glucocorticoid and methotrexate. Twenty-two patients were treated with tumor necrosis factor antagonist in addition to glucocorticoid and methotrexate.  Conclusions  The risk of different clinical manifestations of Blau syndrome from high to low was arthritis, followed by rash, ocular involvement and fever. The main treatment was glucocorticoid combined with methotrexate, to which biological agents could be added.
