Previous studies have agreed that the levels of neuron-specific enolase (NSE)and S100B protein have an important value for the severity of cerebral infarction and prognosis estimation. This article reviews the relationship between the serological changes of NSE and S100B and cerebral infarction, infarct volume, severity of neurological deficits, infarct location,and prognosis, as well as the advances in research on the evaluation of therapeutic drugs.

Objective To investigate the correlation between the changes of serum neuron specific enolase(NSE) and hypersensitive C-reactive protein (hs-CRP) levels and the degree of neurological deficit (NIHSS)score in patients with cerebral infarction.Methods From January 2017 to January 2019,63 patients with cerebral infarction admitted to Lishui Central Hospital were selected.According to NIHSS score,they were divided into 13 mild cases,30 moderate cases and 20 severe cases.According to infarction area,they were divided into large area group(16 cases),small area group (27 cases) and lacunar infarction group (20 cases).Another 60 cases underwent health examination in our hospital from January 2017 to January 2019 were selected as the control group.Enzyme-linked immunosorbent assay (ELISA) was used to determine the content of NSE,and immunoturbidimetric assay was used to determine the content of hs-CRP.The changes of serum NSE and hs-CRP levels in the cerebral infarction group and control group,serum NSE,hs-CRP levels and NIHSS scores in different severity and infarction area,and the correlation between serum NSE and hs-CRP changes and NIHSS scores were compared.Results The serum levels of NSE [(21.34 ± 3.27) ng/mL] and hs-CRP [(10.48 ± 2.14) mg/L] in the cerebral infarction group were significantly higher than those in the control group [(6.23 ± 1.08) ng/mL,(2.83 ± 0.46) mg/L] (t =34.061,27.095,all P ＜ 0.05).The serum levels of NSE [(26.98 ± 3.64) ng/mL],hs-CRP [(15.36 ± 2.57) mg/L] and NIHSS score[(38.49 ±3.25) points] in the severe group were higher than those in the moderate group and mild group,which in the moderate group [(20.98 ± 3.21) ng/mL,(10.25 ± 2.09) mg/L and (22.18 ± 3.48) points]were higher than those in the mild group [(12.64 ± 2.78) ng/mL,(5.47 ± 1.40) mg/L and (7.38 ± 2.56)],the differences were statistically significant (F =14.975,9.132,15.873,all P ＜ 0.05).The serum levels of NSE[(25.43 ± 3.35) ng/mL],hs-CRP [(16.54 ± 2.71) mg/L] and NIHSS score [(37.34 ± 3.75) points] in the large area group were higher than those in the small area group and lacunar infarction group,which in the small area group [(21.67 ± 3.12) ng/mL,(10.86 ± 2.21) mg/L and (21.25 ± 3.26) points] were higher than those in the lacunar infarction group [(13.45 ± 2.97) ng/mL,(4.79 ± 1.35) mg/L and (8.49 ± 2.15) points],the differences were statistically significant (F =13.241,9.893,17.482,all P ＜ 0.05).The serum levels of NSE and hs-CRP were positively correlated with NIHSS score (r =0.829,0.713,all P ＜ 0.05).Conclusion The levels of serum NSE and hs-CRP in patients with cerebral infarction increase with the progression of the disease,and there is a linear positive correlation between NSE and hs-CRP and NIHSS score.It is considered that NSE and hs-CRP are of great value in evaluating the degree of neurological impairment,the severity of the disease and the size of the infarct.

OBJECTIVE: To observe the therapeutic effect of Xincang Decoction on chronic airway inflammation in children with asthma in clinical investigation. METHODS: Xincang Decoction was composed of Flos Magnoliae (Xinyi) and Fructus Xanthii (Cangoerzi), the traditional Chinese herbs for expelling wind. Sixty cases of children with bronchial asthma in remission stage were randomly divided into two groups. Thirty cases in the treatment group were treated with Xincang Decoction and the others in the control group were treated with ketotifen fumarate. The therapeutic effects of the two groups were compared, and the peripheral eosinophil (EOS) count, the levels of immunoglobulin E (IgE), interleukin 4 (IL-4) and interleukin 5 (IL-5), and the pulmonary functions were observed before and three months after the treatment. RESULTS: After three months treatment, the results showed that the total response rates of the treatment and the control group were 83.3% and 80.0%, respectively, without marked difference (P>0.05). The levels of EOS and IL-5 were obviously decreased after the treatment, and the levels of EOS and IL-5 of the patients in the treatment group were lower than those in the control group (P<0.05). Meanwhile the forced expiratory volume in one second (FEV(1)) was improved after the treatment, and the FEV(1) of the patients in the treatment group was higher than that of the patients in the control group (P<0.05). CONCLUSION: Xincang Decoction can decrease the levels of EOS and IL-5 and improve the pulmonary function in treating chronic airway inflammation in children with bronchial asthma in remission stage.

By using single spleen colony transplantation technique and sex chromosome typing as natural cytogenetic markers, we have been able to demonstrate that most spleen colony forming cells in the adult bone marrow or in foetal liver of inbred LACA or C57 mice possess the potential of re-establishment of myeloid and lymphoid lines of cells in lethally irradiated mice. However, most of the spleen colony forming cells in the peripheral [blood of normal mice possess weak or no potentiality to proliferate or re-establish hemopoiesis in lethally irradiated mice. Our results support the notion that the CFU-S population in mice is heterogeneous.From the nature of colony forming cells in the peripheral blood of normal mice, we are convinced that the assessment of CFU-S content relying upon the spleen colonies as the unique sign to indicate the self-renewal ability of a spleen colony forming cell is by no means valid inasmuch as some plu-ripotent . hemopoietic progenitors derived from pluripotent hemopoietic stem cells may have the same ability to form colonies in vivo.

Objective To investigate the sedative effect of different doses of buccal dexmedeto-midine premedication during peri-anesthesia in pediatric patients undergoing tonsillectomy and/or ade-noidectomy.Methods Eighty pediatric patients undergoing tonsillectomy and/or adenoidectomy in department of otorhinolaryngology,54 males and 26 females,aged 4-12 years,ASA Ⅰ or Ⅱ,from June,2014 through May,201 6 were enrolled,n =20 in each group.Children were randomly assigned to receive buccal dexmedetomidine 0 μg/kg (group A),1 μg/kg (group B),2 μg/kg (group C)and 4μg/kg (group D)60 min before transporting to operating room.Sedation score (OAA/S scale)was monitored before and after administering buccal dexmedetomidine.Time of post-operative first spon-taneous respiration,opening eyes,extubation,anxiety score (SAS scale),as well as OAA/S scale, pain intensity (FLACC),and adverse events 60 min after surgery were recorded.Results Compared with group A and group B,markedly superior OAA/S within 60 min after administering buccal dexmedeto-midine in group C and group D were observed (P < 0.05 ).Compared with group A and group B,the OAA/S score 5 min after extubation was lower in group D.FLACC scores within 30 and 60 min after extu-bation in group D were lower than those in group A.Group D showed obviously prolonged time of post-op-erative first spontaneous respiration,opening eyes and extubation compared with the other groups (P <0.05).All the rates of adverse events were similar.Conclusion 2 or 4 μg/kg premedecation of buccal dexmedetomidine 60 min before transporting to operating room can effectively and safely sedate pediatric pa-tients when entered operating room,improve parental separation,mask and sevoflurane acceptance,as well as decrease the stress induced by intubation and post-operative pain.

Aim To discuss the effects and mechanism of Ganoderma lucidum polysaccharides and metformin on myocardial structure and hemodynamics in type 2 diabetic rats.Methods High fat diet combined with intraperitoneal injection of low dose streptozotocin 30 mg· kg -1 was applied to establish rat model of type 2 diabetes mellitus .The diabetic rats were randomly into normal control group ,diabetes group , ganoderma lucid-um polysaccharides group (600 mg· kg -1 ) , metformin group ( 600 mg · kg -1 ) , combination group ( ganoder-ma lucidum polysaccharides 300 mg · kg -1 +metform-in 300 mg· kg -1 ) .After 12 weeks′treatment,the lev-els of fasting serum glucose were determined and the hemodynamic parameters (LVSP,LVEDP,dp/dtmax,-dp/dtmax ) were determined.Collagen volume fraction ( CVF ) was detected by Van Gieson . Immunohisto-chemical method and Western blot were used to detect myocardial tissue MMP-2 protein expression .Results The fasting blood glucose was significantly decreased in the combined treatment group .Combined medication could significantly improve hemodynamic parameters in diabetic rats: reduced LVEP and raised LVEDP , dp/dtmax and -dp/dtmax .CVF was significantly decreased in combination group .The expression of MMP-2 in my-ocardial tissue was significantly inhibited .Conclusions The combination of Ganoderma lucidum polysaccha-ride and metformin can significantly improve the hemo-dynamic parameters in type 2 diabetic rats, and have a preventive effect on diabetic cardiomyopathy . The mechanism may be related to the down regulation of the expression of MMP-2.

Objective To observe and compare the variation of insulin resistance and pancreatic β-cell function in pregnant women with abnormal and normal glucose metabolism during the first,second,and third trimesters,and to explore the feasibility of early diagnosis of gestational diabetes mellitus(GDM).Methods This is a prospective study.507 pregnant women with regular antenatal care from February 2009 to March 2010 were included in the study.Based on the results of oral glucose tolerance test,the patients with GDM consisted of 58,86,and 66 subjects respectively in the first,second,and third trimesters.The control group included 72,164,and 66 subjects respectively in the first,second,and third trimesters.Homeostasis model assessment insulin resistance index( HOMA-IR),homeostasis model assessment β-cell function (HOMA-β),area under curve of glucose (AUCG),area under curve of insulin ( AUCI ),30-minute insulin increase to 30-minute glucose increase ( △I30/△G30 ),and insulin sensitivity index composite(ISIcomp) were calculated for the evaluation of insulin resistance and pancreatic β-cell function.Results ( 1 ) AUCG and AUCI in the GDM group were statistically higher than those in control group while △I30/△G30and ISlcomp in the GDM group were statistically lower than those in the control group during the first trimester(P＜0.05),but HOMA-IR showed no statistically significant difference between two groups.In the GDM groups HOMA-IR,AUCG,and AUCI were statistically higher,whereas △I30/△G30 and ISIcomp were statistically lower than those in the control groups during the second and third trimesters (P ＜ 0.05 ). HOMA-β showed no statistically significant differences between the GDM groups and control groups during 3 trimesters.( 2 ) During thefirst,second,and third trimesters,blood glucose reached its peak by 0.5 h in the oral glucose tolerance test,and insulin reached its peak by 0.5-1 h in the control groups; while in the GDM groups the respective figures were 1 h and 2 h.Conclusions The insulin resistance in GDM patients diagnosed during the first,second,and third trimesters was higher than in pregnant women with normal glucose metabolism,and the peaks of blood glucose and insulin reached in oral glucose tolerance test were respectively delayed.The impaired pancreatic β-cell insulin secretion in GDM patients was present from early pregnancy.Thus for high-risk groups,oral glucose tolerance test during early pregnancy will be helpful for screening abnormal glucose metabolism.

Objective To explore the risk factors of dysphagia in the patients with traumatic brain injuries (TBI). Methods 141 TBI patients were assessed with Gugging Swallowing Screen, and divided into the dysphagia (n=36) and normal (n=105) groups. The related factors were compared between 2 groups. Results The frequency increased in severe brain injury, brain stem injury, bilateral brain injury, tracheotomy, nasal-gastric tube insertion and cognitive defect in the dysphagia group compared with those in the normal group (P<0.05). Conclusion The severe brain injury, brain stem injury, bilateral brain injury, tracheotomy, nasal-gastric tube insertion and cognitive defect may be related with the dysphagia post TBI.

Objective To investigate the effects and mechanism of evodiamine on the proliferation and apoptosis of osteosarcoma MG-63 cells.Methods MG-63 cells were cultured with evodiamine for 24 hours,and the cell proliferation was evaluated by methyl thiazolyl tetrazolium (MTT) assay.Cell cycle arrest,apoptosis and intracellular Ca2+ accumulation were evaluated by flow cytometry.BALB/C mice model of osteosarcoma was established to investigate the tumor inhibitory effect of evodiamine on human osteosarcoma.Wnt/β-catenin signaling protein expressions in osteosarcoma cells were detected by Western blotting.Results As concentration of evodiamine increasing (0.25 μmol/L,0.5 μmol/L,1.0 μmol/L,2.0 μmol/L and 4.0 μmol/L),the inhibition rate of MG-63 ceils increased [(4.18 ± 1.26)％,(15.49 ± 2.26)％,(40.55 ± 6.57)％,(49.87 ±7.69)％ and (60.42 ±8.29)％].The difference was statistically significant between 2.0 μmol/L group and the control group (t =-2.66,P ＜ 0.05).MG-63 cells were cultured with 2.0 μmol/L evodiamine for 24 hours,and the apoptotic rate was (64.67 ± 8.63) ％,the proportion of S phase cells was (85.33 ± 9.31)％,the fluorescence of Ca2+ was 97.33 ± 21.31.The corresponding data of the control group were (4.94 ± 0.81) ％,(43.67 ± 8.92) ％ and 28.67 ± 8.92,the differences were statistically significant (t =-11.90,P ＜ 0.05;t =-7.22,P ＜ 0.05;t =-6.65,P ＜ 0.05).On mice model,the tumor weight of evodiamine group and the control group was (2.15 ±0.35)g and (4.29 ±0.49)g respectively,the difference was statistically significant (t =7.95,P ＜ 0.05).Comparing with the control group (1.00 ± 0.00),evodiamine decreased the expression of β-catenin protein (0.72 ± 0.36) and increased the expressions of Bax (1.15± 0.27) and Caspase-3 (1.46 ± 0.18) protein,and the differences were statistically significant (t =-3.05,P ＜ 0.05;t =-6.42,P ＜ 0.05;t =-5.85,P ＜ 0.05).Conclusion Evodiamine inhibits proliferation and induces apoptosis of human osteosarcoma MG-63 cells by blocking Wnt/β-catenin signaling.
