Objective To study the effects of repetitive transcranial magnetic stimulation(rTMS) of the supplementary motor area(SMA)on the cortical excitability in patients with Parkinson's disease(PD).Methods Sixteen patients with PD were included in this study.The motor evoked potentials(MEP)and the N30 component of somatosensory evoked potentials(SEP) were assessed for each patient before and after 1200 pulses of rTMS of the SMA at 5 Hz and an intensity of 100% of relaxed motor threshold (RMT) for the abductor pollicis brevis.Results Ten minutes after the rTMS intervention,the peak-to-peak amplitude of the SEP component P20-N30 increased significantly(P<0.05),with the P/F index decreased simultaneously(P<0.05).The MEP amplitude increased significantly,and reached the highest value at 10min after the rTMS intervention. Conclusion 5 Hz rTMS of the SMA can improve the excitability of the SMA itself temporarily.Meanwhile,it can induce a short-lasting facilitation of the excitability of M1 connected with SMA.

Objective:Our purpose was to investigate the function of angiotensis converting enzyme(ACE) in the occurrence and development of pregnancy-induced hypertension(PIH). Methods:The study group included 30 pregnant women diagnosed with PIH( 10 mild, 10 moderate, 10 severe). Thirty healthy pregnant women were selected as the control group. The serum was assayed for the activity of ACE by using color comparison method, hippuric acid used as the substrate. Results:The activity of ACE of the study group was significantly higher than that of the control group. Significantly positive correlationships existed between mean blood pressure, degree of adema, level of urine protein,and uric acid. Conclusion:The elevation of serum activity of ACE is related to the occurrence and development of PIH.

Objective To investigate the effect of fusidic acid cream on inflammatory reaction caused by skin barrier damage.Methods Eight male SKH-1 hairless mice were included in this study.The back of each of these mice were equally divided into six regions measuring 1 cm × 2 cm in size,which were then assigned into six groups:blank control group remaining untreated,barrier-impaired group,barrier-impaired and fusidic acid-treated group,barrier-impaired and vehicle-treated group,barrier-unimpaired and fusidic acid-treated group,barrierunimpaired and vehicle-treated group.Stratum corneum was removed by adhesive tape stripping to establish an animal model of acute skin barrier damage in the corresponding skin regions of these mice,and fusidic acid cream or vehicle was topically applied to the corresponding regions once.Twelve hours later,skin surface swab samples were collected from the back of these mice followed by bacterial culture and colony counting.Mice were then sacrificed,and skin tissue specimens were resected from these mice,and subjected to real-time fluorescence-based quantitative PCR for the measurement of the mRNA expressions of myeloid differentiation factor 88 (MyD88),interleukin-1α (IL-1α),IL-6,epidermal antibacterial peptides S100a8 and S100a9.Statistical analysis was carried out by repeated-measures analysis of variance (ANOVA) and least significant difference (LSD) test.Results The mRNA expressions of MyD88,IL-1α,IL-6,S100a8 and S100a9 were all significantly higher in the barrier-impaired group than in the blank control group (all P ＜ 0.05).Specifically,the mRNA expression level of MyD88 in the barrier-impaired group was 8 times that in the blank control group (8.3 ± 3.0 vs.0.8 ± 0.4).Compared with the barrier-impaired group,the barrier-impaired and fusidic acid-treated group showed a significant decrease in the mRNA expressions of IL-1α (2.8 ± 0.3 vs.20.1 ± 10.0,F =47.11,P ＜ 0.01),IL-6 (1.6 ± 2.3 vs.9.4 ± 4.0,F =16.18,P＜ 0.01),S100a8 (1.5 ± 1.4 vs.5.0 ± 1.6,F=59.71,P＜ 0.05) and S100a9 (1.2 ± 0.7 vs.3.4 ± 1.6,F=21.94,P ＜ 0.05).Conlusions Fusidic acid cream could attenuate the inflammatory reaction caused by acute skin barrier damage,which might partly explain its action mechanism in the treatment of inflammatory skin diseases.

Objective To evaluate the inhibitory effect of butyl flufenamate (BT) on ultraviolet (UV)-induced acute skin phototoxic reaction,and to investigate its possible mechanisms.Methods Eight SKH-1 hairless mice were included in this study.The back of each SKH-1 hairless mouse was divided into six regions,which were then randomly classified into six groups:blank group receiving no treatment,UV group receiving UV radiation only,BT + UV group and vehicle + UV group topically treated with BT ointment and vehicle respectively followed by UV radiation,UV + BT group and UV + vehicle group topically treated with BT ointment and vehicle respectively after UV radiation.Skin samples were obtained from these mice at 24 hours after treatment.Subsequently,hematoxylin-eosin (HE) staining was performed,real-time PCR was carried out to detect mRNA expressions of caspase-3,p53,COX-2,PGER1,interleukin (IL)-1β,IL-6,and an immunofluorescence assay was conducted to observe the expression of caspase-3.Statistical analysis was carried out by repeated-measures analysis of variance (ANOVA).Results Compared with the UV group,both BT + UV group and UV + BT group showed a decrease in the degree of skin edema and number of apoptotic cells at 24 hours after UV radiation.Real-time PCR showed that the mRNA expressions of caspase-3,p53,COX-2,PGER1,IL-l β and IL-6 were significantly higher in the UV group than in the blank group (all P ＜ 0.05),but significantly lower in the BT + UV group than in the UV group (all P ＜ 0.05),and only the expressions of caspase-3 and p53 mRNAs were significantly decreased in the UV + BT group compared with the UV group (both P ＜ 0.05).The immunofluorescence assay revealed that the expression of caspase-3 increased in the UV group compared with the blank group,but decreased in both BT + UV group and UV + BT group compared with the UV group.Conclusion BT could partially inhibit UV-induced acute skin phototoxicity in SKH-1 hairless mice.

BACKGROUND:Naringin can increase bonemorphogeneticprotein 2 gene expression and promote the proliferation and differentiation of multipotential stem cel line. In vitro cel experiment indicates that naringin can suppress osteoclast formation and anti-osteoporosis activity.
OBJECTIVE:To prepare a mouse calvarial bone culture model containing naringin and to observe the effect of naringin with different concentrations on the formation and function of osteoclasts.
METHODS:Calvarial bone was dissected out aseptical y from the 4-day-old Sprague Dawley mice, and cultured in the culture medium containing 0, 1, 10 and 100 mg/L naringin. The effects of naringin on the number of tartrate-resistant acid phosphatase-positive osteoclast marker enzyme in calvarial bone and the concentration of calcium in the culture medium were detected after cultured for 1, 3, 7 and 10 days.
RESULTS AND CONCLUSION:After cultured for 1 day, the number of tartrate-resistant acid phosphatase-positive cel s in calvarial bones and the calcium concentration in the culture medium had no difference between the groups. After cultured for 3 and 7 days, the number of tartrate-resistant acid phosphatase-positive cel s was decreased and the calcium concentration was increased with the increasing concentration of naringin. At 10 days after culturing, this trend was most obvious. It showed that naringin could affect the number and function of tartrate-resistant acid phosphatase-positive cel s in calvarial bones, and this effect showed a significant time-and dose-depend manner. The results show that naringin can not only promote the proliferation of osteroclasts, but also reduce the differentiation of osteoclasts or accelerate the apoptosis.

Objective To investigate the complications and outcomes of the treatments in the early time of posterior chamber phakic in-traocular contact lens ( ICL) implantation for the treatment of high myopia, and to analyze the causes. Methods Forty-six patients ( 92 eyes) who underwent ICL/TICL implantations were enrolled in this study. The intraoperative and the postoperative complications in 6 months were observed,at the same time also the treatments and the outcomes were observed. Results None of the patients had a pupillary block. Only 8 eyes in all the patients had an elevated IOP after peripheral iridectomy ( PI) ,and 7 eyes after the ICL implantation,the highest IOP in which was 28 mmHg. No medication was given for treatment. In the YAG PI group,the incidence rate of iris bleeding and pigment dispersion were all higher than that in the YAG PI group (P<0. 05);2 crystalline lens of different patient were damaged intraoperation. Rotation of TICL was observed in 2 eyes. Only 2 individuals of all the patients in this study had complained visual disturbances,which was shadows and glare. Visual psychological change occurred in 1 patient. Conclusion The complications in the early time after ICL implantation for treat-ment of high myopia can prevent and control,the satisfaction of the patients is high.
