Objective To investigate treatment efficacy and the factors influencing prognosis of conservative treatment of hypertensive intracerebral hemorrhage in basal ganglia. Methods A retrospective analysis was conducted on the clinical data of 174 patients with hypertensive intracerebral hemorrhage in basal ganglia who were admitted to our hospital during the period from April 2005 to December 2014. All the patients were given internal medicine conservative treatment and followed up to observe the clinical curative effect to analyze the prognosis. Results Of the 174 patients, 50 patients died and 4 patients were persistent vegetative state. 124 patients were followed up for 2-117 months and they were classified according to ability of daily life(ADL) prognosis scale: 43 cases were in I grade, 53 cases in II grade, 21 cases in III grade, 3 cases in IV grade, 4 cases in V grade. 96 cases achieved favourable outcomes and 28 cases got poor outcomes.The results of Chi square test revealed that GCS scale and intracerebral hemorrhage volume were the factors influencing prognostic of hypertensive intracerebral hemorrhage in basal ganglia. Conclusion There were many prognosis factors related with hypertensive intracerebral hemorrhage. The curative effect and prognosis in patients with conservative treatment is obvious in these patients with high GCS scale and less intracerebral hemorrhage volume.

Objective To investigate the types and incidence of common sequelae in children with bacterial meningitis.To investigate the risk factors for adverse outcome of childhood bacterial meningitis. Methods Selected 129 children with bacterial meningitis all cases were divided into adverse outcome group and favorable outcome group.According to the incidences of different kinds of sequelae,The risk factor effecting bad prognosis were studied. Results A total of 80 children were successfully followed.Of them,12 might only have mild sequelae and 13 had serious sequelaes.Among these children who had serious sequelae,11 of them had mental retardation,8 of them had motor deficit,4 of them had bilateral hearing loss and 4 of them had secondary epilepsy.10 children had multiple serious sequelae,thes most common multiple impairment combinations were mental retardation plus motor deficit.48 parents of the children completed the Child Behaviour Checklist and found out 17(35.42%)of their children had behavioral disorders.Adverse outcome group and favorable outcome group,the length of fever(>7 days),repeated convulsions after admission(≥3 times),coma(Glasgow coma scale score <8 points),septic shock,abnormal pupils,limb movement disorder.There were significantly difference between the two groups(P＜ 0.05). Conclusions This study showed that there are different kinds of sequelaes of children with bacterial meningitis,it indicated that these children should be follow-up to track the effect.On the other hand,this study found out that the high risk factors with adverse outcome might be coma,septic shock and so on.It indicated that if we could identify the high risk factors in the early stage and then interpose them immediately,it might beneficial to improve the quality of life of the children.

Objective The aim is to investigate the effect of ambroxol on radiation lung injury and the expression of transforming growth factor β1(TGF-β1),and tumor necrosis factor α(TNF-α)in plasma. Methods Ninety-eight patients with locally advanced lung cancer in radiotherapy were randomized into treatment and control groups.Patients in the treatment group took ambroxol orally at a dosage of 60 mg,three times per day for 3 months from the beginning of radiotherapy.The expression of TGF-β1 and TNF-αin plasma was analyzed.The clinical symptoms and lung diffusing capacity were monitored using high resolving power computed tomography. Results The level of TGF-β1 in the control group was increased(11.8 ± 5.5 ng/mL),whereas in ambroxol-treated patients,the increase was not significant(5.5 ± 2.6 ng/mL,P＜0.001). Radiotherapy-induced elevation of TNF-α levels,seen in control patients,was also abolished after treatment with ambroxol(5.1 ± 1.3 vs 2.6 ± 0.8 ng/mL,P＜0.001). Conclusion Ambroxol can obviously decrease the plasma TGF-β1 and TNF-α levels after radiotherapy,and decrease the chances of early radiation pneumonitis and late pulmonary fibrosis,and improve treatment effect and quality of life of patients.

目的 观察并评估内毒素性急性肺损伤大鼠吸入一氧化氮后外周血中内皮祖细胞和炎症介质的变化情况。方法 90只SPF级健康大鼠分为3组,A组为正常对照组(n=30),B组为急性肺损伤组(ALI)(n=30), C组为一氧化氮(NO)组(n=30)。分别计算各组外周血内皮祖细胞(Endothelial progenitor cells,EPCs) 数量,同时监测肺组织中白细胞介素-10(Interleukin-10,IL-10)水平和髓过氧化物酶(Myeloperoxidase,MPO)活性。结果 我们成功建立了大鼠的ALI肺损伤模型, C组EPCs数量、MPO活性上升幅度均小于B组、而IL-10上升水平均高于B组,差异有统计学意义(P<0.05)。结论 大鼠吸入一氧化氮可减轻内毒素所致急性肺损伤程度,其机制可能与外周血中内皮祖细胞数量及MPO水平下降和IL-10水平上升有关。

Objective To investigate the effect of nitric oxide(NO) inhalation in endotoxin-induced acute lung injury mice. Methods Ninety SPF mice were randomly assigned to the normal group(group A), ALI group(group B)and ALI+NO group(group C). The number of endothelial progenitor cells was counted and the level of Interleukin-10(IL-10) and myeloperoxidase (MPO) were measured. Results Endotoxin administration resulted in pulmonary edema. The pulmonedema was lightened and the level of MPO were decreased by the inhalation of nitric oxide while the level of IL-10 increased. Conclusion NO inhalation can mitigate acute lung injure. The decline of EPCs and MPO and the increase of IL-10 may be one of the mechanism.

目的 分析经直肠彩超引导下不同前列腺穿刺方式的阳性率及其相关因素,探讨安全的穿刺方案。方法 回顾性分析接受经直肠彩超引导下前列腺穿刺的701例患者临床资料,所有患者均接受系统性13点穿刺活检,并假设13点穿刺中减少前列腺中线3个穿刺点为10点穿刺术式,加之标准的6点穿刺术式。比较上述穿刺术式的阳性率,分析T-PSA、前列腺体积、PSA体积密度(PSAD)、有无前列腺结节对穿刺阳性率的影响。结果 随前列腺穿刺针数的增加,活检阳性率增高。同一穿刺方式,不同T-PSA组间、不同前列腺体积组、不同PSAD组阳性率有差异。T-PSA>100 ng/mL时,三种穿刺方式的阳性率无差异;T-PSA<100 ng/mL时,6点穿刺法阳性率较低,而10点穿刺、13点穿刺阳性率无差异。前列腺体积>80 mL时,不同穿刺法阳性率有差异。PSAD<0.5 ng/mL²时,10点、13点穿刺阳性率无差异。结论 前列腺穿刺活检阳性率随穿刺针数增多而增加,可根据PSA水平、前列腺体积、PSAD选择个体化穿刺方案。
