Objective To study the effects of rehabilitation(RT)on cardiac function in cerebral infarct (CIF)patients with cardiac insufficiency(CIS).Methods Fifty-nine CIF patients with CIS were randomly divid- ed into a treatment group(T group,n=29)and a control group(n=30),and all patients were treated with routine pharmacotherapy for 2 months.In addition,RT was administrated in the T group at the same time.The grading of the New York Heart Association(NYHA)and the changes in cardiac function associated index were observed in both groups before and after treatment.Results Compared with the control group,NYHA grades,left ventricle ejection fraction(LVEF),the levels of brain natriuretic peptide(BNP)in the blood plasma,and the 6min walking range of the T group patients were all significantly improved after treatment(P＜0.05).Conclusion RT can improve car- diac function in CIF patients with CIS.

OBJECTIVETo observe the regulatory effects of electroacupuncture with different acupoints combinations on blood lipid and atherosclerosis index (AI) in rats with hyperlipemia, so as to make a preliminary screening for the optimal acupoints combination for hyperlipemia.

METHODSOne hundred and five clean-grade SD male rats were randomly divided into 9 groups, including a normal group, a model group, a Quchi group, a Zhongwan group, a Fenglong group, a Quchi+Zhongwan group, a Quchi+Fenglong group, a Zhongwan+Fenglong group and a Quchi+Zhongwan+Fenglong group (three acupoints group), 17 rats in the normal group and 11 rats in the rest groups. The normal group was fed with normal diet, while the rest groups were fed with high-fat diet for 3 weeks to prepare the hyperlipemia model. All the rats were given unlimited water. After the establishment of model, the normal group was fed freely without any treatment; the model group was bundled and immobilized everyday; the rest groups were bundled, immobilized and treated with electroacupuncture at corresponding acupoints with disperse-dense wave, 20 min per time, once a day. After 4 weeks, the blood examples were collected from abdominal aorta to measure the total cholesterol (TC), triglyceride (TG), high-density lipoprotein (HDL-C) and low-density lipoprotein (LDL-C), and analyzed the AI in each group.

RESULTSAfter the treatment, TC, TG, HDL-C, LDL-C and AI in each acupuncture group were all lower than those in the model group (P<0.05, P<0.01). Compared with single acupoint group and the Quchi+Zhongwan group, the content of TC in the three acupoints group was lower (P<0.01). The differences of content of TG among each acupuncture group were not significant (all P>0.05). Compared with the rest 6 acupuncture groups, the content of HDL-C and AI in the three acupoints group were significantly different (all P<0.05). The content of LDL-C in the three acupoints group was decreased as compared with the Quchi group and the Zhong-wan group.

CONCLUSIONThe electroacupuncture at "Quchi" (LI 11), "Zhongwan" (CV 12) and "Fenglong" (ST 40) has more advantages on regulating the content of HDL-C and LDL-C as well as improving AI in hyperlipemia rats, and it has superior effects on blood lipid metabolism.

Objective To study the effects of IL-4 in prostate cancer cells glycometabolism and proliferation. Methods We used IL-4 to treat PC3 cells, then tested the changes of LDH-A expression by RT-qPCR, Western Blot, CCK-8 and lactate production assay. Results Our data showed that IL-4 induced LDH-A up-expression in PC3 cells at mRNA and protein levels. Also, IL-4 promoted the proliferation activation and increased lactate production in PC3 cells. Conclusion IL-4 can strengthen the proliferation activation in PC3 cells by up-regulating LDH-A expression.

Objective To investigate the impact of rapid eye movement (REM) sleep on the rat brain.Methods Microtubule-associated protein 2 (MAP2) and neurofilament (NF) were used as two neuronal cytoskeleton markers.The modified multiple platform method (MMPM) was used to deprived rats of sleep.The immunohistochemistry method and Western blot technique were used to detect the expression of MAP2 and NF,together with the electromicroscope study to show the neurodegeneration in rat cerebral cortex and hippocampus.Results The expression of MAP2 and NF in cerebral cortex and hippocampal neurons decreased after 5-day sleep deprivation.Some uhrastructural changes were seen in those areas as well,such as displacement of the nucleus,slightly swollen mitochondrial and endoplasmic reticulum,dissolution or condensation of sheaths of some axons.Neurons in cortex with degenerated ultrastrutrue accounted for 1.2% ,3.6% and 5.8% in tank control group,sleep deprivation 5 d group and sleep deprivation 7 d group respectively.Conclusion REM sleep deprivation can induce neurodegeneration in rat brain,but these morphological changes are tiny enough to be considered as reversible.

Objective To study the effects of peroxisome proliferators-activated receptor gamma (PPA?r) on the biological characteristics of hepatic stellate cells (HSCs); Methods The activated HSCs were divided into four groups: control group, rosiglitazone group, GW9662 + rosiglitazone group and GW9662 group. The cell proliferation was determined with MTT colorimetric assay, The cell apoptosis was studied with flow cytometry. The expression of PPA?r, Type I collagen were detected by RT-PCR, Western blot and immunocytochemistry. Results MTT of HSCs in rosiglitazone group was (0. 49?0. 06) significantly lower than in control group ( 1. 00?0. 045 ), GW9662 group (0. 89?0. 043 ) , GW9662 + rosiglitazone group (0.78?0.049)(t = 15.59,14.68,8.07, P

Objective To improve the recognition of intramedullary spinal abscess by a case of congenital dermal sinus with intramedullary spinal abscess and reduco the incidence of congenital dermal sinus with intramedullary spinal abscess.Methods Clinical,laboratory data and image of a confirmed case about one infant of congenital dermal sinus with multiple intramedullary spinal abscess were investigated,the related literature was reviewed.Results In this case,when the infant with congential dermal sinus had infection,he failed to gain antibiotic therapy, timely surgical treatment,his infection had diffused, and multiple intramedullary spinal abscess flared up.Conclusions Intramedullary spinal abscess is a rare disease.If treatment is delayed, the prognosis is poor and the mortality rate is high.MRI is the ideal investigation for diagnosis.Intramedullary spinal abscess can happen subsequent to congenital dermal sinus with infection, and cause neurological sequela. So an infant with congenital dermal sinus should be offered to avoid complication caused by infection.

AlM:To investigate the prevalence of pterygium of the household population aged 40 and above in Hengli Town of Dongguan.
METHODS: Using the method of cluster random sampling, select 3 628 people aged 40 and above in four villages and one community for visual examination, intraocular pressure check, slit lamp examination and questionnaire.
RESULTS: The actual number of subjects was 3 393 people, and examination rate was 93. 52%. We detected 843 patients with pterygium. The prevalence of pterygium was 24. 85%.
CONCLUSlON:There is high prevalence of pterygium in Dongguan area. The prevalence of pterygium is related with age and working environment, but has no relation with gender.
