The acute and chronic respiratory tract inflammation models were made to investigate the effect and mechanism of sterol extracts from Begonia Sinensis Rhizome (BSR). The first model of acute lung injury was made with Kunming mice by inhaling cigarette smoke, then the mice were treated with different concentrations of BSR sterol extracts. Lung tissue morphology was detected by HE staining, TNF-alpha/MPO were detected by Elisa, and cPLA2 protein were, detected by Western blotting respectively. Results showed that in model group, lung sheet became real, alveolar space shrank or disappeared, alveolar septum was thickened, plenty of inflammatory cells were infiltrated, capillary blood vessels were congestive and the expression of TNF-α, MPO, cPLA2 increased; after administration, a small amount of inflammatory cells were infiltrated, alveolar septum became obvious, capillary congestion status was significantly relieved and the expression of TNF-α, MPO, cPLA2 decreased (P < 0.05). The second model of chronic respiratory tract inflammation in BALB/c mice with bronchial asthma was induced by OVA, then the mice were treated with different concentrations of BSR sterol extracts. Lung tissue morphology was detected by HE staining, indexes such as IL-4, IL-5, IL-13 were detected by Elisa, and the cPLA2 protein expression was detected by Western blotting respectively. Results showed that in model group, a lot of inflammatory cells around lung vessels and bronchi exuded, bronchial goblet cells proliferated and the expression of IL-4, IL-5, IL-13, cPLA2 increased; after administration, inflammatory and goblet cell hyperplasia reduced, the expression of IL-4, IL-5, IL-13, cPLA2 also decreased (P < 0.05). The above results showed BSR sterol extracts could resist against respiratory inflammation by inhibiting cPLA2 in a dose-dependent manner.

Objective To observe the action of lowering blood fat of Agaricus blazei Murill ?-6 polyunsaturated fatty acid(?-6APFA) on hyperlipemia rats and mice.Methods Sixty rats were randomly divided into control group,model group,natural soybean phospholipids capsule(NSPC)0.70 g?kg~(-1) group,?-6APFA 0.28,(0.14,)0.07 g?kg~(-1) groups(n=10).The other groups except control group were given high-fat diets for 14 d,on the fourteenth day the rats were administered orally,the control group and model group were administered distilled water 10 mL?kg~(-1) at the same volume,14 days after continuous administration,rats were anesthetized,the blood were extracted from abdominal artery,T-CHO,TG,HDL-C,LDL-C in sera were determined. At the same time,the activity of SOD in liver and the content of MDA were determined,the fat accumulated coefficient was calculated.72 male mice were randomly divided into control group,model group,NSPC 1.0 g?kg~(-1) group,(?-6APFA)0.4,0.2,0.1 g?kg~(-1) groups(n=12).Mice were administered continuously,16 h before the last administration,except control group,the mice in the other groups were injected 75% yolk physiological salt solution 0.5 mL through the abdominal cavity,and began to starve,1 h after the last administration,blood was extracted from eyeball,serum T-CHO and TG were determined.Results Compared with model group,T-CHO and TG in rats treated with NSPC 0.70 g?kg~(-1) and ?-6APFA 0.28 g?kg~(-1) all reduced and HDL-C raised obviously(P0.01).)Compared with model mice,T-CHO and TG in acute hyperlipemia mice treated with NSPC 1.0 g?kg~(-1) and ?-6APFA0.4,0.2 g?kg~(-1) reduced obviously(P
6.Value of instructions to outpatients in helping postgraduates of thoracic surgery promote their clinical abilities
Chinese Journal of Medical Education Research 2006;0(11):-
Education to medical postgraduates is relatively special. Their study and research work have something to do with their clinical practice. Based on their technical training for thoracic surgery,postgraduates were demanded to follow up and instruct their patients on postoperative recovery from surgery. In this way,these postgraduates were trained not only in clinical practice but also in other aspects,such as communication techniques,how to take care of patients,professional moral education. Instruction to outpatients is helpful to cultivate post-graduates and promote their abilities in self-thinking,self-acknowledging,initiative,creation,and so on. Instruction to outpatients is an important way to bring up excellent medical postgraduates.

Objective This study aims to examine the development of the posterior lateral line of the zebrafish and establish ant model to study the process of hair cell differentiation and regeneration .Methods We observed the posterior lateral line system formation by DAPI immunohistochemistry and whole mount in situ hybridization .We further evaluated hair cells differentiation within neuromast by using Transgenic Tg (Brn3c:mGFP) zebrafish and stained the functional hair cells by the mechanotransduction marker FM 1 -43FX .We labelled proliferating cells in primordium and neuromast by addition of BrdU to the system water .Results The posterior lateral line primordium originated from a sensory placode and started its journey at around 20 hours post fertilization to migrate along the horizontal myoseptum to the tail -tip with a constant speed (1 .7somite/hour) .The primordium depositd five or six neuromasts spaced along the body ,and two or three terminal neuromasts at the tail -tip at 48 hours post fertiliza-tion .At 3 ,5 and 7 days post fertilization ,zebrafish contained 5 .68 ± 1 .46 ,10 .1 ± 0 .99 ,and 12 .45 ± 1 .32 hair cells per neuromast ,respectively .Furthermore ,the average number of FM1-43FX stained hair cells within each neuro-mast were 3 .68 ± 1 .11 ,8 .18 ± 1 .86 ,and 10 .22 ± 1 .24 ,respectively .Conclusion We establish the development model of hair cells in zebrafish lateral line neuromast and suggest that 3 to 7 days post fertilization is an important period for lateral line neuromast differentiation .This study would be useful for underlying the mechanisms of hair cell differentiation and regeneration .

To investigate the curative effect of minimally invasive sclera buckling on single retinal detachment.METHODS:Totally, 100 cases of patients with retinal detachment ( 106 eyes ) enrolled in our hospital were randomly divided into observation group and control group, 53 eyes in each group. Patients in observation group were treated with minimally invasive sclera buckling, while patients in control group received traditional limbal conjunctival incision. After surgery, patients were all followed up for 6 ~18mo, during which the retinal recurrence situation, degree of vision enhancement and compliance occurrence rate was recorded. RESULTS: The retinal reattachment rate once of observation group (96. 22%) was significantly higher than that of control group (88. 68%), there was statistically significance (P<0. 05). The vision enhancement rate of observation group (84. 90%) was significantly higher than that of control group (71. 70%), there was statistically significance (P<0. 05). The compliance occurrence rate of observation group (11. 32%) was significantly lower than that of control group (32. 08%), there was statistically significance (P<0. 05).CONCLUSlON: The improved minimally invasive sclera buckling can significantly enhance the curative effect for retinal detachment, decrease the compliance occurrence rate, improve vision function, and is a scientific, practical and rigorous tool for retinal detachment treatment.

Objective To find methods to isolate and purify plasminogen activator (Pla) from artificial culture of Yersinia pestis. Methods Ultrasonication and urea extracting combined by ammonium sulfate salting-out were tried to extract Pla. High performance liquid chromatography(HPLC) was used to purify Pla. The first step was ion exchange and the second was gel filtration, Preparative electrophoresis was used to purify Pla, too. The enzyme activity of the isolated or purificated Pla was detected. Results Both 50% - 60% saturated ammonium sulfate deposition of supernatant of plague bacilli ultrasonication and 0 - 10% saturated ammonium sulfate deposition of supernatant of plague bacilli powder soaked by urea had three bands(Mr about 31×103, 35×103 and 37×103) and lysis rings were 6.5 and 7.2 mm in diameter respectively when the enzyme activity was detected. Pla purified by HPLC was mainly composed of three bands(Mr about 31×103, 35×103 and 37×103), occupying more than 80% of total protein weight and lysis ring was 5.0 mm in diameter. Pla purified by preparative electrophoresis mainly consisted of three bands(Mr about 31×103, 35×103 and 37×103) with other proteins of low concentration nearby, no lysis ring was detected. Conclusions Pla is collected by the methods of ultrasonication and urea extracting. Priliminary purification of Pla can be achieved by HPLC and preparative electrophoresis.
