“黄风湿”系列疗法——火针封闭治疗痛风石的疗效观察

痛风是一种由嘌呤代谢紊乱所致的疾病,日久不愈、反复发作则逐渐形成痛风石沉积。常规治疗对痛风石效果不明显。黄再军医院采用火针封闭疗法治疗痛风石36例,经临床观察治愈率为69.4%,显效率为25.0%,有效率为5.6%,总有效率达100%。     

用逆转录—聚合酶链反应法对类胰岛素生长因子cDNA的扩增

逆转录-聚合酶链反应(RT-PCR)法是将PCR方法与逆转录法结合应用,可快速高效地扩增某一基因的全cDNA。类胰岛素生长因子-I(IGF-I)在人染色体中只有一个基因,全长超过45kb,并有内含子,其cDNA却只有几百个bp,为了表达得到IGF-I,本文利用RT-PCR方法,从胎肝提出的混合mRNA中,筛选并扩增了IGF-I的cDNA。经过分子克隆与测序,证明不需制备胎肝cDNA库,即可快速获得IGF-I的cDNA。

支气管结核纤维支气管镜下局部清理、注药与联合微波治疗的疗效比较

支气管结核患者由于支气管局部的肉芽组织增生、溃疡、干酪性坏死、管腔狭窄阻塞等改变，虽然使用强有力的全身抗痨方案治疗，亦很难将其治愈，常常迁延不愈，局部结构组织破坏明显，引起永久性狭窄、闭塞，导致肺不张、毁损肺等严重的并发症。全身抗痨结合纤维支气管镜清理支气管局部的增生肉芽、坏死组织后注入异烟肼、链霉素的方法可使疗效明显提高。近年来微波技术已逐渐应用于通过纤维支气管镜治疗多种气道疾病。现将我院近5年来确诊的支气管结核用纤支镜局部病灶清理、注抗痨药治疗与同时联合微波热灼治疗的疗效进行分析、报告如下。     

Infrared spectrum and nuclear magnetic resonance analysis of the alkaloid extract of Gelsemium produced in east Guangdong province]

OBJECTIVE: To identify the structure of the alkaloid extract of Gelsemium from east Guangdong province of China. METHODS: Fourier transform infrared (FTIR) absorption spectrometry, hydrogen and carbon spectra of nuclear magnetic resonance (NMR) and distortionless enhancement by polarization transfer (DEPT) analysis were used for the structural identification of the alkaloid exstract of Gelsemium. RESULTS: The frequency, intensity and shape of the extract's characteristic peaks in infrared absorption spectra (4,000.0-400.0 cm(-1)) and (1)H NMR, (13)C NMR were recognized and compared. The molecular structure of the sample was consistent with the theoretically derived model. CONCLUSION: The extract is structurally identical to koumine, which may provide evidence for its safe clinical application and establishment of Chinese medicine fingerprint database of Gelsemium.     

Dose reduction for the management of indinavir-related toxicity in human immunodeficiency virus type 1-infected patients in Taiwan: clinical and pharmacokinetic assessment.

This study evaluated the feasibility of reducing the indinavir (IDV) dosage in Taiwanese patients receiving the standard IDV/ritonavir (RTV) dosage of 800/100 mg twice a day who had undetectable plasma human immunodeficiency virus type 1 (HIV-1) RNA but had developed IDV-related toxicities. After dosage reduction to IDV/RTV 600/100 mg twice a day, the dose-related toxicity decreased and plasma HIV RNA remained undetectable at 24 weeks post-switch in all patients. The maximal plasma concentration (Cmax) and area under the plasma concentration-time curve of IDV decreased significantly (median, 6.3 vs 4.3 microg/mL and 1892 vs 1292 microg.min/mL, p=0.01 and 0.001, respectively) but the minimal plasma concentration remained at a similar level (median, 1.0 vs 0.8 microg/mL, p=0.12). This study found that the reduction in the dosage of IDV in HIV-1 infected patients receiving the standard IDV/RTV regimen guided by therapeutic drug monitoring decreased the Cmax, dose-related toxicity and medical cost without compromising viral control.

Inhibition of the ubiquitin-proteasome system: a new avenue for atherosclerosis.

BACKGROUND: The ubiquitin-proteasome system (UPS) is thought to be functionally active in atherosclerosis (AS) lesions. Aspirin was found to be a potent inhibitor of the UPS in some tumour studies; however, its effect on AS remains to be demonstrated in vivo. METHODS: New Zealand rabbits were placed on a normal diet (N) or on a normal diet with aspirin (NI) or on an atherogenic diet without (H) or with aspirin (HI) for 12 weeks. Proteasome activity, concentrations of plasma lipids and levels of peroxidation were determined. Ubiquitin/ubiquitin-conjugates (Ub), IkappaBalpha, phosphorylated IkappaB (pIkappaBalpha) and p65 were investigated by Western blotting or immunochemistry. RESULTS: Concentrations of plasma lipids and peroxidation levels were higher in H or HI vs. N or NI. Histological analysis showed that atheroma was increased in H. Ub and IkappaBalpha were mainly localised in subendothelium and media vascular smooth muscle cells. Western blots revealed that Ub, IkappaBalpha, and pIkappaBalpha were increased, whereas p65 was lower in HI vs. H. The activity of the 20S proteasome was functionally active in H vs. N, NI or HI, while the 26S proteasome was not affected in any of the groups. CONCLUSIONS: Aspirin can attenuate the pathogenesis of atheroma formation, the degradation of IkappaBalpha and pIkappaBalpha, and lower the expression of p65, indicating that its therapeutic effects on AS may be via inhibition of the UPS.     

慢性鼻窦炎鼻息肉合并支气管哮喘患者鼻窦内镜术后对支气管哮喘疗效的影响

目的观察鼻窦内镜术(endoscopic sinu ssurgery，ESS)对慢性鼻窦炎伴支气管哮喘患者哮喘发作的影响。方法对210例慢性鼻窦炎患者施行ESS术，其中伴有支气管哮喘病史者42例(20．0％)。210例患者均于术前、术后采用酶联免疫吸附测定法(ELISA)检测外周血单个核细胞(PBMC)培养上清液中的白细胞介素4(IL-4)，干扰素γ(IFN-γ)，可溶性白细胞介素2受体(sIL-2R)和可溶性IgE低亲和力受体(solube CD23，sCD23)的含量，并与20例正常对照组进行比较。通过主观和客观标准评定42例患者哮喘发作及对皮质类固醇的耐受状况，并对术后患者进行为期1年(10例)和3年(32例)的随访。结果鼻窦炎合并支气管哮喘患者术前PBMC培养上清液中IL-4，sIL-2R、sCD23含量较对照组显著升高，而IFN-γ含量较对照组显著减少。术后IL-4、sIL-2R、sCD23含量较对照组显著降低，而IFN-γ含量显著增高。术后哮喘改善水平由随访术后1年的45％提高到术后3年的70％。42例中32例(76％)哮喘发作次数明显减少，术前长期服用类固醇的2l例中，14例(67％)减少了对口服类固醇的使用。结论ESS对慢性鼻窦炎伴支气管哮喘患者的治疗有较满意的远期疗效。ESS能调节IL-4、IFN-γ sIL-2R、sCD23水平，降低哮喘的发作频率和对类固醇的依赖。     

Electrophysiological evaluation in 4 patients with diabetic pseudotabes

BACKGROUND: Researches on diabetic nervous system lesion are mainly focus on peripheral nerve and vegetative nerve, so there are few investigations on diabetic pseudotabes. OBJECTIVE: To investigate the electrophysiological examinations on the diagnosis of diabetic pseudotabes. DESIGN: Case study. SETTING: Department of Electrophysiology and Department of Neurology, Zhongshan Hospital Affiliated to Xiamen University. PARTICIPANTS: A total of 4 patients with type 2 diabetes mellitus, including 3 males and 1 female aged from 50 to 72 years, were selected from Department of Neurology, Zhongshan Hospital Affiliated to Xiamen University from March 2002 to February 2005. All accepted subjects met the modified diagnostic criteria of diabetes mellitus, which was set by American Diabetes Mellitus Association (ADA) in 1997. Otherwise, the subjects had typical symptoms and physical signs of spinal posterior funiculus damage. However, patients with spinal cord lesion which was caused by other factors were excluded. All accepted subjects provided the confirmed consent. METHODS: Nicolet NT electromyography (EMG)/evoked potential meter (made in the USA) was used to detect spinal cord conduction velocity (SCCV), somatosensory evoked potential (SEP) of lower limbs, motor nerve conduction velocity (MNCV) and sensory nerve conduction velocity (SNCV) of extremities. Determining criteria: Measurements were performed based on the laboratory standards. SCCV, which was less than lower limit of normal value (T2–12: 40–55 m/s, T12–L4: 20–41 m/s, T2–L4: 36–45 m/s), was regarded as abnormal. SEP value of lower limbs: P40, P60 and PF, which were more than standard deviation of normal value (x(—)+2.5), were regarded as the abnormality. Normal value of P40, P60 and PF latencies (x(—)±s) in this study: P40, P60 and PF in males were (37.6±1.9) ms, (59.8±3.9) ms and (7.6±0.9) ms, respectively; meanwhile, those in females were (35.5±1.7) ms, (55.2±2.7) ms and (6.3±0.7) ms, respectively. MNCV and SNCV, which were less than 50 m/s in upper limbs and 40 m/s in lower limbs, were regarded as the abnormality. MAIN OUTCOME MEASURES: Electrophysiological examinations. RESULTS: All 4 patients with type 2 diabetes mellitus were involved in the final analysis. ① SCCV: Among 4 patients, SCCV of three patients was decreased in T2–12, T12–L4 and T2–L4, and that of the other one was decreased in T2–12 and T2–L4; however, SCCV in T12–L4 was normal. There was significant difference as compared with normal value (P < 0.01). ② SEP of lower limbs: SEP values of lower limbs were abnormal in all 4 patients. Among them, P40, P60 and PF latencies of two patients were delayed; P40 of one patient was delayed and PF was not drained out; P40 and P60 of the last one were delayed and PF was normal. ③ MNCV and SNCV: The MNCV and SNCV were normal in one patient and abnormal in three patients. The results demonstrated that MNCV and SNCV of extremities decreased; especially, sensory nerve action potential (SNAP) of both lower extremities of one patient were not drained out. CONCLUSION: Detections of SCCV, SEP of lower limbs, MNCV and SNCV of extremities are helpful to investigate whether peripheral nerve and deep sensory passage are damaged or not and determine whether deep sensory damage is caused by peripheral nerve and spinal posterior funiculus.
