BACKGROUND: The efficacy of Cyclosporin A(CyA) in the treatment of psoriasis is well recongized, the dosage less than 5mg/kg per day(mg/kg/d) is recommended. OBJECTIVE: The purpose of this study is to evaluate the indication, dose, course and side-effects of CyA therapy for psoriasis, especially in China. METHODS: Forty patients with psoriasis were treated with doses of CyA 5mg/kg/d, compared with 20 patients treated with Tigason lmg/kg/d by Global PAST. RESULTS: 1. Of 40 patients 33 patients (82.5%)were cured clinically in 4-5weeks and all the patients(100%) had responses to the therapy. 2. The efficacy and the Global PASI reduction of CyA therapy were significantly better than that of Tigason therapy. 3. During the CyA therapy, no severe side-effects and obvious laboratory changes were found. CONCLUSION: CyA(5mg/kg/d) was satisfactory for psoriasis, especially for psoriasis pustulosa, arthropathica and erythroderma. CyA was found to be superior to Tigason. The therapy course and side-effects seemed to be related to the dosage.

The resident match system established in 1952.And since then almost all of the senior medical students and international students have applied a position of resident training in this national system.They seek a respective resident program and hospital for training while the hospital hires students they preferred.The match procedure includes submitting application,interview of selected candidates,submitting rank-order list of both parties,centralizing matching service by computer and announcement of the results in Match Day.This is a relatively stan-dardized,rational and fair system which we can learn something from.

Objective To investigate the effects of ult rasonic cavitation on cell membrane cultured in vitro. Methods The rat pulmonary artery vascular smooth muscle cells were divided into three groups, control group, simple ultrasound radiation group and contrast plus ultrasound radiation group.The latter two groups were exposed to ultrasound(665 kHz, 0.5- W/cm 2) for 20 s but the last group with contrast agent. Immediately after the experiment or 24 hours after treatments, electron microscopic scanning was used to observe the membrane change. Results Compared with control group, the cell structure and cell surface had no apparent changes in the second group treated with ultrasound alone. In the third group, nearly 20% cells exhibited small holes with diameter mostly about 1-2 ?m in the cell surface and returned to normal appearance after 24 hours later. Conclusions Ultrasonic cavitation can cause small transient holes in cell surface and hence increase permeability of the cell membrane. It might be the main mechanism for gene delivery with ultrasound contrast agents.

Ashi point (tonsil) in combination of the pricking and bleeding technique on Shaoshang (LU 11 )and Shangyang (LI 1) were used to treat 58 outpatients of acute tonsillitis. The results showed cure in 38 cases,remarkable effect in 17 cases and failure in 3 cases by one treatment, and the total effective rate in 95%.

The entry of the modern information technology and the appearance of the new teaching medium cause the new ed-ucational pattern innovations, bring the life and vitality to the medical physics education in medicine institutions of higher learning. This paper analyzed the current situation of the modern information technology application in medical physics teach-ing briefly, put forward several problems about the modern information technology application in medical physics teaching, and discussed the medical physics network course construction in medicine institutions of higher learning.

Purpose To investigate the significance of u-PA and PAI-1 expression in various types ofglomerulonephritis. Methods The expression level of u-PA, PAI-1, type-Ⅳ collagen and PCNA positivenuclei in 120 cases of renal biopsies from patients with various types of glomerulonephritis were detected byimmunohistochemical method. Both the staining intensity of u-PA and PAI-1 in glomeruli were quantitativelyanalyzed by image analysis. Results The expression intensity of u-PA and PAI-1 was different in varoustypes of glomerulonephritis, which were significantly higher than that of the minor lesion group. Meanwhile,the intensity of PAI-1 stain was significantly higher than that of u-PA in various types of glomerulonephritis( P ＜ 0.05). The increase of u-PA expression was closely related to increase of type- Ⅳ collagen synthesis andhypercellularity in glomeruli(r = 0. 761 and 0. 811, P＜ 0.05), while the expression of PAI-1 was closelyrelated to the increase of Col-Ⅳ synthesis other than the cell proliferation in the glomeruli. ConclusionsThe over expression of u-PA and PAI-1 may play an important role in contributing to the pathogenesis anddevelopment of glomerulonephritis.

Objective To investigate the changes of stress response on inhalation-intravenous general anesthesia during pericystectomy for Liver hydatid cyst. Methods Thirty ASA I-II patients with liver hydatidosis for pericystectomy were studied. The blood from right jugular vein were collected for measurement of serum cortisol (Cor) concentrations and glucose (BG) levels, and MAP, HR and BIS were observed and recorded at different point-times: pre-intubation for 1 min, post-intubation for 3 min, pre-incision for 1 min, post-incision for 3 min, post-incision for 10 min, post-surgical exploration 10 min. The data of pre-intubation and pre-incision served as controls. Results The levels of Cor concentration of post-incision for 10 min were decreased than those of pre-intubation and pre-incision (P<0.05); MAP of post-incision for 10 min and post-surgical exploration for 10 min were increased than those of pre-intubation and pre-incision (P < 0.01); For HR, the data of post-surgical exploration 10 min was much quicker compared with pre-incision (P < 0.01), which is slower than that of pre-intubation(P<0.01). Conclusion Inhalation-intravenous general anesthesia may inhibit the stress response during intubation,incision and surgical exploration for liver hydatidosis pericystectomy. Hemodynamic changes during incision may reflect the trend of stress response in advance.

Objective: The Phenomenon of different species with the same name has created potential threats to cinical safety of medication. Because of that, two kinds of “gonglao leaf” and their sibling adulterants have been identified by molecular methods in this study, to secure its safety in medication. Methods: Ilexcornuta, Mahoniabealei, Mahoniafortuneiand their sibling adulterants total of 9 species 45 samples were collected in this experiment,Total genomic DNA was extracted from them by the method of improved CTAB, ITS2 sequences were amplified, and the PCR products were sequenced. Sequence assembly and consensus sequence generation were performed by the CodonCode Aligner V 4.2.4.. The genetic distances were computed by MEGA 6.0 in accordance with the Kimura 2-Parameter (K2P) model and the phylogenetic tree constructed by the neighbor-joining (NJ) method. Results: The analysis results of the genetic distances, variable sites and the NJ phylogenetic tree showed that Ilexcornuta, Mahoniabealei, Mahoniafortunei were seperated from their sibling adulterants obviously. Conclusion: ITS2 sequence was able to identify two kinds of “gonglao leaf” and their sibling adulterants which can provide a basis for clinical accurate medication.

Some grain sprouts herbs recorded in Chinese Pharmacopoeia 2010, including Oryzae Fructus Germinatus, Setariae Fructus Germinatus and Hordei Fructus Germinatus, together with their adulterants, were identified by ITS2 sequences. The genomic DNA were extracted, their ITS2 sequences were amplified, and purified PCR products were
sequenced. Sequences were assembled using the CodonCode Aligner. The genetic distances, variable sites and the neighbor-joining (NJ) phylogenetic tree were computed by MEGA 6.0 in accordance with the Kimura 2-Parameter (K2P) model. The results showed that their intraspecific genetic distances were all much lower than the interspecific ones of themselves and their adulterants. The NJ tree based on ITS2 sequence indicated that Oryza sativa, Setariaitalica, and Hordeum vulgar formed one monophyletic clade respectively, in addition any one of the grain sprouts herbs and its adulterants could be distinguished clearly. Therefore, ITS2 sequence is suitable to be as a barcode to identify the grain sprouts herbs and their adulterants.
