Objective To explore the significance of LDH and ?2-m concentration in CSF in differentiating viral meningitis from purulent meningitis in pediartic patients.Methods Kinetic method was performed to detect the LDH concentration in CSF in 45 patients with purulent meningitis and 49 patients with viral meningitis and 22 healthy children of control group respectively.On the other hand,radioimmunoassay(RIA)was used to detect the concentration of ?2-m.Results The concentrations of LDH in CSF in purulent meningitis group(26.15?12.17)U/L were higher than that in viral meningitis group(8.76?4.94)U/L significantly(P

【Objective】 To investigate the effect of Weishu Powder (WP) on acute liver injury induced by carbon tetrachloride (CCl_4) in mice. 【Methods】 Fifty mice were randomized to normal control group (group A), model group (group B), bifendate pills group (group C), low-dose WP group (group D) and high-dose WP group (group E). The mice in the above groups were fed with the corresponding drugs by gastric infusion for 7 days. On the 8th day of feeding, the mice except those in group A were given 0.5% CCl_4 peanut oil solution (10 mL/kg) by intraperitoneal injection. Sixteen hours later, liver weight, serum level of alanine aminotransferase (ALT), malondialdehyde (MDA) content and necrotic focus amount in the liver were observed. 【Results】 As compared with the normal group, liver weight, serum ALT level and necrotic focus amount were increased in model mice with CCl_4-induced acute liver injury (P

Objective To investigate the effects of Baicalin on intestinal mucosal injury in rats with partial common bile duct ligation (PCBDL).Methods Forty male Wistar rats were randomly divided into 4 groups equally:sham operation,PCBDL,PCBDL1 and PCBDL2.Rats in PCBDL,PCBDL1 and PCBDL2 groups were subjected to partial common bile duct ligation.Baicalin [80 mg/(kg · d)] was fed in PCBDL1 group (for 2 weeks) and PCBDL2 group (for 3 weeks),while for other groups,9 g/L saline in the same volume was fed.Ileum mucosa were prepared for microscopic examination.The intestinal mucosal injury in rats was observed and scored.The level of NF-κB mRNA expression by Fluorescent in Situ Hybridization,and the level of NF-κB protein were determined by immunohistochemistry.Results 1.Compared with PCBDL group (3.2 ± 0.5),the pathological severity scores of intestinal mucosa significantly declined (F =21.120,P < 0.01) in PCBDL1 group (1.9 ± 0.2) and PCBDL2 group (1.5 ± 0.3).2.Compared with sham operation group(0.066 ± 0.006),PCBDL1 group (0.107 ± 0.011),and PCBDL2 group (0.098 ± 0.010),NF-κB expression in PCBDL group (0.155 ± 0.012) presented significantly up-regulation (F =76.8,P < 0.01).3.Compared with sham operation,PCBDL1 group,and PCBDL2 group,the positive expression rates of NF-κB mRNA of intestinal mucosal epithelium in PCBDL group significantly increased.Conclusions It is suggested that Baicalin exert protective effects on the intestinal mucosal injury in rats with PCBDL,partially by inhibiting NF-κB mRNA,down-regulating NF-κB protein expression of intestinal mucosal epithelial cells.

Objective To evaluate the clinical characteristics and the clinical outcomes of perianal abscess (PA) in neonates.Methods A retrospective review was performed on the collected data of 185 patients of PA in neonates prospectively admitted to Binzhou Medical University Hospital from January 2008 to December 2015.Patients were divided into 2 groups on the parents' intention:nonsurgical treatment and surgical treatment,the standard surgical treatment for PA was incision and drainage with the use of packing.The standard surgical treatment for PA was surgical incision drainage of lower abscess under local anesthesia by the use of filling tamponade iodoform gauze,while the patients receiving conservative treatment took hip bath perianally with topical 1 ∶ 5 000 potassium permanganate,besmearing erythromycin eye ointment outside locally.Incision-thread-drawing procedure was recommended in fistula-in-ano (FIA) after 6 months.Antibiotics were administered in all patients in the early days.The clinical data of age,gender,accompanying diseases,abscess amount and location,treatment approach,healing time and recurrence rates were analyzed with statistical method.Results All patients were boys,time of visiting hospital was 1-25 day,the average time 7.5 days;60 cases (32.4%)had neonatal diarrhea,45 cases (24.3%)had neonatal jaundice,but no patients had severe fever.A single skin lesion was present in 145 patients (78.4%),2 lesions in 30 patients (16.2%),and 10 patients had 3 lesions (5.4%).The most commonly affected sites were at 9 o'clock clockwise direction with 115 (62.2%)lesions on lithotomy position,followed by 3 o'clock clockwise direction with 65(35.1%) lesions by 1 o'clock clockwise direction with 3 (1.6%) lesions and 6 o'clock clockwise direction with 2 (1.1%) lesions.Bacteria cultures were obtained from 123 patients (90.4%,123/136 cases) of surgical treatment and 35 patients (71.4%,35/49 cases) of nonsurgical treatment obtained the results of bacteria culture.The average healing time was (21 ±2) days (10-60 days) in the surgical treatment group,and (36 ± 3) days (9-90 days) in the nonsurgical treatment group,7 out of 136(5.1%) patients had a recurrence with surgical treatment,incision drainage was performed again with the use of packing,and FIA was not found,10 out of 49 (20.4%) patients had a recurrence with nonsurgical treatment group,and 6 out of 49 (12.2%) were spontaneously resolves within the first year of life,4 out of 49 (8.1%) developed into FIA,incision-thread-drawing procedure was performed after 6 months.The significant difference was observed between and nonsurgical treatment and surgical treatment in healing time (t =-6.707,P =0.000),recurrence (x2 =11.347,P =0.001) and FIA formation rate (x2 =10.054,P=0.002).Conclusions PA is an entity in neonates.Incision and drainage of PA is an effective and safe therapy in the early days.Surgery for PA may result in low recurrence rates,a low rate of evolution toward FIA,and a short healing time,which should be considered as the primary treatment.The key procedure is to keep the drainage unobstructed by the use of filling gauze drainage to prevent crissum abscess recurrence.Postoperative care with antibiotics is effective to shorten hospital stays.

Objective:To analyze the coronary angiographic (CAG) characteristics of coronary artery lesion (CAL) in children with Kawasaki disease (KD), and to clarify the necessity of CAG in the diagnosis and treatment of KD combined with CAL in children.Methods:It was a retrospective study to analyze the clinical data, electrocardiogram, echocardiography, time and findings of CAG in children with KD and CAL who underwent CAG in Shanghai Children′s Medical Center of Shanghai Jiao Tong University School of Medicine from January 2013 to August 2022.The distribution, type, severity, and prognosis of CAL were analyzed.Results:A total of 117 children with KD and CAL were included in the analysis.The onset age of KD was from 2 months to 12.8 years old, and the age of performing CAG was from 8 months to 18.1 years old.A total of 234 coronary artery lesions were detected in 117 cases.Among them, CAL in the right coronary artery (RCA), left anterior descending branch (LAD), left main coronary artery and left circumflex artery were detected in 96 branches(41.1%), 78 branches(33.3%), 44 branches(18.8%), and 16 branches(6.8%), respectively.Unilateral coronary artery involvement was detected in 43 cases (36.8%), of which LAD was the dominant; while bilateral involvement was detected in 74 cases (63.2%), among which, LAD and RCA were the most involved arteries.Stratified by the degree of coronary involvement, large coronary aneurysms and severe coronary stenosis were most frequently occurred in the RCA and LAD.In contrast, 10 cases (13.6%), 20 cases (24.3%), 55 cases (45.8%) and 37 cases (67.3%) of intraluminal lesions were found in small, medium and large coronary aneurysms, and stenosis or occlusion, respectively.The incidence of intraluminal lesions tended to be higher in the site of severe lesions.CAG showed stenosis or occlusion in a total of 55 cases, and collateral circulation at varying degrees was found in cases of severe stenosis or occlusion.Conclusions:CAL in children with KD are complex and varied.Although clinical symptoms, routine electrocardiogram and cardiac ultrasound may indicate severe CAL.Their applications are limited by the diagnosis of the type (especially stenosis), degree, and extent of CAL, as well as the detection of extracoronary lesions.CAG is of great significance to identify vascular lesions and guide clinical management of KD combined with CAL in children.
