0.05). Conclusion:There is bigger difference process of tumor apoptosis between different cell types in the same topography site. Survivin may play adjuvant roles and Bcl-2 may play main roles in the inhibition of cell apoptosis in SCLC while the case is just reversed in NSCLC,it suggests that there were different apoptosis inducing factor and different apoptosis pathway due to different cell type in NSCLC and SCLC.

Objective To observe the alteration of scavenger receptor class A types Ⅰand Ⅱ (SR-AⅠ/Ⅱ) gene knock-out on lipid metabolism in mice fed with high-fat diet, and explore the underlying mechanism. Method The SR-AⅠ/Ⅱgene knock-out and wild-type male mice were fed with normal and high-fat diet for 12 w. Thereafter, the level of lipid metabolism (such as the levels of lipids in blood and liver) was detected with enzyme method or oil red O staining, and the expression of scavenger receptor class B typeⅠ(SR-BⅠ) and CD36 in liver was analyzed by RT-PCR. Results Under high-fat diet condition, as compared with wild-type mice, the levels of TG, TC, LDL and HDL in SR-AⅠ/Ⅱgene knock-out mice were decreased at 3, 6, 12 w (P0.05). Conclusion The alteration of lipid metabolism induced by high-fat diet in SR-AⅠ/Ⅱgene knock-out mice might be relative with the up-regulated SR-BⅠmRNA expression and the counter transport of peripheral lipids to liver.

Objective To investigate the effect of point massage on swelling pain alleviation of breast during neonatal maternal separation.Methods 100 cases of parturients with neonaml maternal separation were randomly divided into the experimental group and the control group with 50 patients in each,the control group received routine breast care,the experimental group was given breast point massage from the first day after delivery for consecutive 3 days.Subjective evaluation of breast swelling paill,breast hardness,breast duct smooth and breast filling degree were compared and analyzed on the third day postpartum.Results For the experimental group,the self evaluation of breast pain was significandy lower,while the breast hardness,breast filling degree and breast duct smooth were better on the first 3 days postpartum than the control group. Conclusions Breast point massage Can significantly reduce the level of swelling pain for parturients with neonatal and maternal separation.

Objective To compare the therapeutic effect of electroacupuncture, warm needling therapy and acupuncture on the third lumbar transverse process syndrome. Methods 90 patients were assigned to receive electroacupuncture therapy (n=30), warm needling therapy (n=30) and acupuncture therapy (n=30) for 20 times. They were assessed with Visual Analogue Scale (VAS) and Japanese Orthopaedic Association (JOA) scoring systems for lower back pain before and after treatment. Results The scores of JOA increased and the scores of VAS decreased significantly in all the groups after treatment (P<0.001). Both the scores were better in the electroacupuncture group (P<0.05). Conclusion Electroacupuncture, warm needling therapy, and acupuncture are effective on the third lumbar transverse process syndrome, among which the electroacupuncture is most effective.

Objective To promote the differentiation of Flk1+CD31-CD34-cells isolated from adult adipose tissues into pancreatic islet endocrine cells in vitro.Methods Flk1+CD31-CD34-cells were first cultured and plated in medium supplemented with B27,epidermal growth factor(EGF),and basic fibroblast growth factor(bFGF).Next,the culture medium was changed.The glucose concentration in the serum-free medium was increased.At the same time,betacellulin and nicotinamide were added.Reverse transcription polymerase chain reaction(RT-PCR) was used to detect the expression of nestin,ngn3,insulin promoter factor-1(IPF-1),insulin,and glucagon before and after differentiation induction;immunofluorescent staining for nestin,insulin and glucagon and radioimmunoassay(RIA) for insulin.Results Initially,a nestin positive precursor cell population was found,then small round cells increased in number after 6 days.Later on,they were differentiated into islet-like clusters.The induced cells resulted in the formation of clusters which exhibited higher insulin secretion and other pancreatic endocrine hormones.RT-PCR detected an enhanced expression of pancreatic genes in the differentiated cells.Immunofluorescence revealed a high percentage of insulin-expressing cells in the clusters.Furthermore,the intra-cellular insulin content was detected by RIA after the induction culture.Conclusion These cells represent a previously unidentified adult intrinsic pancreatic precursor population and are a promising candidate for cell-based therapeutic strategies.

Objective To investigate the therapeutic effect of oat ?-glucans on liver injury in hyperlipemia rats.Method Rats were fed on high fat forage for 3 w to establish hepatic injury model,then the model group was orally given oat ?-glucans at doses of 133,266 and 533 mg/(kg bw.d) respectively.At the same time,there were 3 control groups including 200 mg/(kg bw.d) chitosan oligosaccharide,normal and liver injury(model group fed with distilled water).Serum levels of ALT and AST,the content of MDA in serum and liver homogenate was assayed.Results Oat ?-glucans at high dose obviously decreased the levels of ALT,AST and MDA in the liver injury models,SP had a better protective effect on the liver injury than oligosaccharide did.Besides,in the treated group with ?-glucans,degenerative and necrotic changes of the liver cells were apparently milder than those of the untreated group.Conclusion Oat ?-glucans can obviously relieve the liver injury in hyperlipemia rats.

ObjectiveTo investigate the therapeutic effects of patients with non-acquired immunodeficiency syndrome ( AIDS )-related cryptococcal meningitis treated with fluconazole and flucytosine.MethodsA retrospective study was conducted including 52 cases of non-AIDS-related cryptococcal meningitis,which were divided into two groups:the amphotericin B combined with flucytosine group (n =32) and the fluconazole combined with flucytosine group (n =20 ). The comparison between groups was done by t test and chi-square test.ResultsThe intracranial pressure of the amphotericin B combined with flucytosine group and the fluconazole combined with flucytosine group were (221.9±76.2) and (213.4±99.2) mm H2O,respectively (t=0.302,P＞0.05) ; the cryptococcus counts in the cerebrospinal fluid (CSF) were (351 ± 1180) and (508 ± 943)/mL,respectively (t=- 0.473,P＞0.05) ; the CSF protein levels were (0.754 ± 0.726) and (0.649 ±0.308) g/L,respectively (t=0.578,P＞0.05) ; the CSF white blood cell (WBC) counts were (16±25) × 106/L and (28±32) × 106/L,respectively (t=-1.348,P＞0.05).The cured rates were 59.38％ (19/32) and 35.00％ (7/20),respectively in the amphotericin B combined with flucytosine group and the fluconazole combined with flucytosine group,and the improved rates were 6.25％(2/32)and 25.00％ (5/20),respectively,the uncured or mortality rates were 34.38％ (11/32) and 40.00％ (8/20),respectively,and the difference were not significant of cured rates (x2 =2.925,P＞0.05) and uncured or mortality rates (x2 =0.168,P＞0.05) between two groups.ConclusionFluconazole combined with flucytosine also has a good effect on the treatment of cryptococcal meningitis.

Objective To explore the efficacy of sequential or combined amphotericin B (AmB) and fluconazole (FCZ) therapy on a 5 flucytosine based regimen in non-acquired immunodeficiency syndrome (AIDS)-related cryptococcal meningitis.Methods A tatal of 117 cases of non-AIDS-related cryptococcal meningitis treated with 5-flurocytosine-based regimens were retrospectively divided into five groups:AmBgroup (n=38),FCZ group (n=25),FCZ and AmB sequential group (n=18),AmB and FCZ sequential group (n=15),AmB and FCZ combination group (n=21).The number in cerebrospinal fluid (CSF) of the five groups were compared.Statistical analyses included t test,oneway analysis of variance,K-independent samples test and chi-square test.Results Intracranial pressure of AmB group,FCZ group,FCZ and AmB sequential group,AmB and FCZ sequential group,AmBandFCZ combination group were (208.6±75.1),(191.5±94.5),(185.0±76.3),(201.9±69.7) and (223.1±89.3) mm H2O (1 mm H2O=0.0098 kPa),respectively,and the differences were not statistically significant (F=0.611,P =0.656).Median cryptococcus counts in CSF of the five groups were 0,10,0,3 and 0/mL,respectively,with no statistical significance (x2 =7.638,P-0.090).CSF protein levels of the five groups were 0.55,0.69,0.67,0.53 and 0.96 g/L,respectively,with no significant differences among groups (F=7.063,P=0.133).The cure rates of the five groups were 55.3％ (21/38),32.0％ (8/25),9/18,6/15 and 47.6％ (10/21),respectively;progression rates or mortality of the five groups were 28.9％ (11/38),44.4％ (11/25),5/18,4/15and 23.8％ (5/21),respectively; and the differences among cure rates (x2 =3.638,P=0.457) and progression rates or mortality (x2-2.785,P =0.604) were not statistically significant.Conclusion FCZ or AmB alone,sequential or combined therapy were all effective in the treatment of cryptococcal meningitis.

Objective To investigate the expression of nerve growth factor(NGF) and slouble Fas(sFas) in children with viral myocarditis(VM),and the relationship with immunity,with the aim to provide evidence and basis for the diagnosis and treatment of VM.Methods The serum levels of NGF and sFas were detected by two-site enzyme-linked immunosorbent assy(ELISA) in 43 children with VM,and 20 normal heathy children as controls.Results The serum levels of both NGF and sFas in children with the acute stage(course in less than month and 1-2 months)and the procrastinate and chronic stages of VM were significantly higher than those of healthy children(P0.05).Conclusion The increased serum expression levels of NGF and sFas are related to the process of viral myocarditis,which confirms the relationship between the onset of VM and immune factors.
