ABSTRACT

OBJECTIVE:To observe the effects of nimodipine on peripheral facial paralysis and hearing in mimetic convulsion patients after microvascular decompression. METHODS:162 mimetic convulsion patients underwent microvascular decompression were enrolled in this study,and then randomly divided into control group and observation group,81 cases in each group. Control group was given routine microvascular decompression,and observation group was additionally given intravenous pump of Nimodip-ine injection 40 mg,qd,2 mg/h for consecutive 3 days after operation,and then given Nimodipine tablet 40 mg,qd,for 10 days. The incidence of peripheral facial paralysis and hearing disorder,onset time,duration time and severity of facial paralysis were ob-served in 2 groups. RESULTS:The incidence of peripheral facial paralysis and hearing disorder were 8.6% and 6.2% in observa-tion group,which were significantly lower than 14.8%and 11.1%of control group,with statistical significance(P<0.05). The on-set and duration time of peripheral facial paralysis was(15.32±3.15)d and(36.52±5.84)d in observation group,which were sig-nificantly later and lower than(12.21±2.16)d and(44.73±6.57)d of control group,with statistical significance(P<0.05). Ac-cording to House-Brackman classification method,the incidence of Ⅲ、Ⅳ facial paralysis was lower in control group than that in observation group,with statistical significance (P<0.05). CONCLUSIONS:Nimodipine can significantly decrease the incidence of peripheral facial paralysis and hearing disorder in mimetic convulsion patients after microvascular decompression,and contrib-utes to the recovery of injured nerve function.

ABSTRACT

Objective To analyze the H3 protein histone acetylation modification conditions in I region of human gliomas GDNF gene promoter and to explore the expression of human glioma GDNF gene promoter. Methods A total of 20 cases of patients with normal brain tissue were chosen, and the detection method of reverse transcription (RT-PCR) was used to detect the associated expression method of GDNF gene promoter. On the basis of real-time quantitative fluorescent PCR (Real-time PCR), Chromatin immunoprecipitation (CHIP) was established. 20 cases of patients with human glioma were chosen, and reverse transcription method was implemented to detect the relevant expression of GDNF gene promoter. On this basis, CHIP method was established to analyze the H3 protein histone acetylation modifi-cation conditions in I region of human gliomas GDNF gene promoter. Results By real-time quantitative fluorescent PCR method in checking human glioma GDNF gene expression, with the elevated detected levels of RT-PCR, the ex-pression amount increased. There were statistically significant differences in comparing the normal-level transcription group, the low-level transcription group and the high-level transcription group (P<0.05). Conclusion H3 protein histone acetylation modification conditions in I region of human gliomas GDNF gene promoter is likely to affect the related expression of GDNF-related genes.

ABSTRACT

<p><b>BACKGROUND</b>Protectin D1 (PD1), derived from docosahexaenoic acid, has been shown to control and resolve inflammation in some experimental models of inflammatory disorders. We investigated the protective roles of protectin D1 in pulmonary inflammation and lung injury induced by lipopolysaccharide (LPS).</p><p><b>METHODS</b>Mice were randomly assigned to six groups (n = 6 per group): sham-vehicle group, sham-PD1 group, sham-zVAD-fmk group, LPS-vehicle group, LPS-PD1 group, and LPS-PD1-zVAD-fmk group. Mice were injected intratracheally with 3 mg/kg LPS or saline, followed 24 hours later by intravenous injection of 200 µg/mouse PD1 or vehicle. At the same time, some mice were also injected intraperitoneally with the pan-caspase inhibitor zVAD-fmk. Seventy-two hours after LPS challenge, samples of pulmonary tissue and bronchoalveolar lavage fluid were collected. Optical microscopy was used to examine pathological changes in lungs. Cellularity and protein concentration in bronchoalveolar lavage fluid were analyzed. Lung wet/dry ratios and myeloperoxidase activity were measured. Apoptosis of neutrophils in bronchoalveolar lavage fluid (BALF) was also evaluated by flow cytometry.</p><p><b>RESULTS</b>Intratracheal instillation of LPS increased neutrophil counts, protein concentration in bronchoalveolar lavage fluid and myeloperoxidase activity, it induced lung histological injury and edema, and also suppressed apoptosis of neutrophils in BALF. Posttreatment with PD1 inhibited LPS-evoked changes in BALF neutrophil counts and protein concentration and lung myeloperoxidase activity, with the outcome of decreased pulmonary edema and histological injury. In addition, PD1 promoted apoptosis of neutrophils in BALF. The beneficial effects of PD1 were blocked by zVAD-fmk.</p><p><b>CONCLUSION</b>Posttreatment with PD1 enhances resolution of lung inflammation during LPS-induced acute lung injury by enhancing apoptosis in emigrated neutrophils, which is, at least in part, caspase-dependent.</p>

ABSTRACT

The methods for measurement of blood flow contain dilution, electro-magnetism, nuclear magnetic resonance, Doppler etc. The dilution, which includes heat dilution, 131Xe, etc., can not display the moving blood flow in real-time. The expenses of nuclear magnetic resonance expenses are very high. Electromagnetism must be used in the surgical operation. And ultrasound Doppler can not record other parameters of hemodynamics synchronously. This paper brings up a kind of blood flow measuring method with simple operating rules, dependable performance, and low cost to meet the needs in hemodynamic studies. The differential pressure between stay and fluxion points of the tube is produced in proportion to the square of velocity while fluid flows through the tube. We not only measure blood pressure or transfer drug using the detention catheter with double chamber, but also detect the differential pressure related within blood flow. The result of detecting cerebral blood flow (CBF) in clinical setting shows this method can record the diagram of dynamic blood flow and is a valid was of detecting blood flow for hemodynamic studies.
