Objective To investigate the changes of ubiquitin C-terminal hydrolase-L1 (UCH-L1) and glial fibrillary acidic protein (GFAP)in acute phase of cerebral infarction. Methods From March 2011 to June 2012,95 patients with early cerebral infarction from the Neurology Clinic,the Emergency Department and the Cerebral Apoplexy Screening Project Base,and the Neurology Ward of Renhe Hospital were used as an infarction group;61 non-stroke subjects received physical examination in the Physical Examination Center of our hospital in the same period were used as a control group. The cerebral infarction group and the patients with cerebral infarction in different onset of time groups (an onset < 12 h group and an onset 12-24 h group),the different National Institutes of Health Stroke Scale (NIHSS)score groups (NIHSS 0 -4 group and NIHSS 5 -19 group),and the levels of UCH-L1 and GFAP in the control group were measured and compared among the groups. The receiver operating characteristic (ROC)curve was established. The cut-off values of the relevant parameters in the diagnosis of cerebral infarction,and the sensitivity and specificity of diagnosis were obtained. Results The UCH-L1 and GFAP values of the cerebral infarction group were all higher than those of the normal control group (0. 13[0. 09,0. 21]μg/ L vs. 0. 05[0. 02,0. 13]μg/ L,0. 030[0. 008,0. 130]μg/ L vs. 0. 004[0. 004,0. 020]μg/ L,Z values were 3. 62 and 4. 95 respectively;all P < 0. 01). The UCH-L1 and GFAP values of the NIHSS score 5 -19 group were higher than those of the NIHSS score 0 -4 group (0. 12[0. 08,0. 21]vs. 0. 09[0. 08,0. 18],0. 07 [0. 01,0. 11]vs. 0. 04[0. 01,0. 10];all P < 0. 05). There was no significant difference in the UCH-L1 and GFAP values between the onset 12 -24 h group and the onset < 12 h group (0. 12[0. 08,0. 21]μg/ L vs. 0. 09[0. 08,0. 18]μg/ L,0. 030[0. 010,0. 110]μg/ L vs. 0. 040[0. 008,0. 100]μg/ L;all P > 0. 05). The analysis results of ROC curve of UCH-L1 and GFAP for diagnosis of acute cerebral infarction showed that when the plasma UCH-L1 was ≥0. 18 μg/ L,the sensitivity and specificity of UCH-L1 were 68% and 74%respectively;When the plasma GFAP was ≥0. 11 μg/ L,the sensitivity and specificity of GFAP were 70% and 86% respectively. The area under the ROC curve of UCH-L1 and GFAP diagnosis of cerebral infarction were 0. 64 and 0. 71 respectively. Conclusions UCH-L1 and GFAP have obvious change in acute phase of cerebral infarction. UCH-L1 and GFAP may have certain correlation with the severity of stroke.

Objective To analyze the clinical features and prognostic factors of lymphoma.Methods The clinical data,pathologic data and survival state of 253 patients with lymphoma in Qinghai were retrospectively studied.The survival differences of patients with different clinical characteristics and laboratory tests were analyzed using Kaplan-Meier method.The prognostic factors of lymphoma were analyzed by Cox proportional hazards regression model.Results Among all of 253 cases of lymphoma,males were in the majority (male∶female =1.56∶1).The median age of patients was 48 years old.There were two peaks of about 40 years old and 60 years old in age of onset.The nodal lymphoma (56.13 ％) was more commonly than the extranodal lymphoma (43.87 ％).The more common extranodal lymphomas were found in the nasopharynx and gastrointestinal tract.Among all cases,40 cases (15.81％) were confirmed to be Hodgkin lymphoma (HL),of which,the commonest subtype was nodular sclerosis (72.5 ％).While 213 of 253 cases (84.19 ％) belonged to non-Hodgkin lymphoma (NHL),of which,B-cell lymphoma was 148 cases (69.48 ％).Overall,three subtypes including diffuse large B-cell lymphoma (39.91％),follicular lymphoma (12.21％) and peripheral T-cell lymphoma (9.39 ％) were the commonest subtypes among all cases.Univariate analysis showed that the clinical stage,B symptoms,Hb concentration,serum LDH level,international prognostic score (IPI) and treatment programs were related to the prognosis of NHL (P ＜ 0.05).However,the Cox regression multivariate analysis showed that only the clinical stage,IPI and treatment programs,not B symptoms,Hb concentration and serum LDH level,were closely related to the prognosis of NHL (P ＜ 0.05).Conclusions In Qinghai area,there are two peaks of about 40 and 60 years old in the age of onset of lymphoma.The nodal lymphoma is more than extranodal lymphoma.B-cell lymphoma is more common.IPI could be as an independent prognostic factor and might be used to estimate the prognosis of NHL.

Objective To study the effects of Jiedu Quyu Ziyin Prescription (JQZP)-treated freeze dried powder and drug-containing serum on the inflammatory signal pathway of monocyte-macrophage induced by LPS (lipopolysaccharide) in mice. Methods Monocyte-macrophage cells were cultured in vitro and randomly divided into blank group, LPS stimulation group, drug-containing serum group, freeze dried powder group, LPS + drug-containing serum group, and LPS + freeze dried powder group. After 24 h intervention, the optimal concentrations of drug-containing serum and freeze dried powder were screened by CCK8 method and the cell viability was measured respectively. The content of tumor necrosis factor (TNF-α) in cell serum was measured by ELISA. Real-time PCR was employed to test the expression of TNF-α mRNA and nuclear transcription factor kappa-light-chain-enhancer of activated B cells (NF-κB). Western-blot was used to detect the expression of NF-κB protein. The LC-MS was used to detect the active ingredients in the drug-containing serum. Results Compared with the blank group, the expression of TNF-α level, NF-κB, TNF-α mRNA and NF-κB protein in LPS stimulation group were significantly increased (P < 0.05). Compared with the LPS stimulation group, the TNF-α level, NF-κB, TNF-α mRNA and the expression of NF-κB protein in the LPS plus serum group were significantly lower than those in the LPS plus freeze-dried powder group (P < 0.05). Paeoniflorin and ferulic acid were detected in the drug-containing serum. Conclusion JQZP freeze-dried powder and drug-containing serum all have the effect of inhibiting the inflammatory signaling pathway.

OBJECTIVE: To study the effect of serum containing Jieduquyuziyin-prescription (JP) on signal pathway of interleukin-1 receptor-associated kinase 1 (IRAK1) in mononuclear macrophages of mice stimulated by lipopolysaccharide (LPS), and to explore the effect of Jieduquyuziyin-prescription on IRAK1 and NF-κB inflammatory signaling pathways, which providing a good theoretical support for its anti-inflammatory clinical medication. METHODS: In this study, mice mononuclear macrophages cultured in vitro were randomly divided into blank group, LPS group, JP serum group, blank serum group, LPS plus JP serum group, LPS plus blank serum group, IRAK1 inhibitor group, inhibitor plus LPS group, inhibitor plus JP serum group and inhibitor plus blank serum group. After intervention for 24 h, the activity of JP on macrophages was tested by CCK8 method. The IRAK1 expression in macrophages was tested by immunofluorescence chemical staining. The content of TNF-α in the supernatant of the cells was detected by ELISA. The mRNA expressions of IRAK1, NF-κB, TNF-α and IL-6 were detected by RT-PCR. The protein expressions of IRAK1, p-IRAK1 and NF-κB were detected by Western-blot. The LC-MS was used to detect the active ingredients in JP serum. RESULTS: The results show that 2.5% of JP serum is the optimal concentration. Jieduquyuziyin-prescription could down-regulate the expression of TNF-α and IL-6 and inhibit the expression of IRAK1 and activate NF-κB(P<0.05). Paeoniflorin and ferulic acid were detected in the JP serum. CONCLUSION: Jieduquyuziyin-prescription can inhibit the expression of IRAK1 and NF-κB in mouse monocyte-macrophage cells after LPS stimulation and provide a good theoretical support for its anti-inflammatory clinical medication.

BACKGROUND:Dendritic cel s can regulate the immunological reaction in the intestinal tract, this functional deficit may induce inflammatory bowel disease. Tol-like receptor-4/nuclear factor-κB pathway is highly involved in this reaction. OBJECTIVE:To establish experimental colitis model in rats, to observe effects of resina draconis on dendritic cel s and Tol-like receptor-4/nuclear factor-κB expression in rats with experimental colitis, and to explore its action mechanism. METHODS:A total of 44 male Sprague-Dawley rats were randomly assigned to four groups (n=11):blank control group, model group, resina draconis group, 5-aminosalicylic acid treatment group. With the exception of blank control group, 2,4,6-trinitrobenzenesulfonic acid-induced ulcerative colitis models were established in the model group, resina draconis group and 5-aminosalicylic acid treatment group. After the models were successful y established, the rats in the resina draconis and 5-aminosalicylic acid treatment groups were intragastrical y treated with resina draconis [(0.75 g(kg·d)] and 5-aminosalicylic acid [100 mg(kg·d)] respectively for 10 days. RESULTS AND CONCLUSION:Disease activity index, macroscopic colonic damage score and histopathological score were significantly decreased in the resina draconis group compared with the model group (P<0.05). Symptoms and tissue damages were obviously lessened in the 5-aminosalicylic acid treatment and resina draconis groups compared with the model group. Expression rates of CD80 and CD86, as wel as expression levels of Tol-like receptor-4 and nuclear factor-κB were significantly higher in the model group compared with the blank control group, resina draconis group and 5-aminosalicylic acid treatment group (P<0.05, P<0.01). Tol-like receptor-4 and nuclear factor-κB expression was significantly lower in the resina draconis group than that in the 5-aminosalicylic acid treatment group. Experimental findings indicate that, resina draconis can partial y relieve experimental colitis symptoms in rats and effectively inhibit the activation of dendritic cel s in the mesenteric lymph node. Resina draconis can relieve enteric inflammatory reaction by suppressing the expression of Tol-like receptor-4 and nuclear factor-κB in rats.

OBJECTIVETo investigate the characteristics of the tidal breathing pulmonary function in premature infants with different gestational ages.

METHODSA total of 75 premature infants were classified into three groups according to their gestational ages: <32 weeks, 32-33(+6) weeks and 34-36(+6) weeks. Fifty-five full-term infants (39-40 weeks group) were selected as the control group. All infants were given the tidal breathing pulmonary function test at 3-5 days after birth. Moreover, all infants were given the tidal breathing pulmonary function test again at 40 weeks of the corrected gestational age.

RESULTSAt 3-5 days after birth, the three groups of premature infants had significantly lower inspiratory time, time to peak tidal expiratory flow (tPTEF), and ratio of tPTEF to total expiratory time (tPTEF/tE) than the control group (P<0.05). The parameter values of the tidal breathing pulmonary function were lower when the gestational age was lower. Even at 40 weeks of the corrected gestational age, the three groups of premature infants still had significantly lower tPTEF and tPTEF/tE than the control group (P<0.05).

CONCLUSIONSThe tidal breathing pulmonary function of neonates is influenced by the gestational age. The tidal breathing pulmonary function of premature infants is obviously impaired, and the lower the gestational age, the more obvious the impairment.
