Objective:To investigate the clinical application of enternal nutrition support via jejunostomy catheter after esopha-geal carcinoma excision. Methods:The patients of the parenteral nutrition group (PNn group) received completely parenteral nutrition support. The patients of the external nutrition group (EN group) received total intravenous nutrition support on the first day after the sur-gery. And the nutritional targets and immunological function were timely examined at different points. Results:The time of postopera-tive exhaust, defecation and hospital stay were all shorter in EN group than in the PN group (P<0.05). The index of nutritional and im-mune function was better in en group than in pn group. Conclusion:The enteral nutrition can improve the nutritional status, and can maintain and promote the postoperative gastrointestinal function of the esophageal cancer patients.

Objective To explore clinical characteristics of Chinese patients with lupus erythematosus (LE).Methods Data were obtained from the Lupus Erythematosus Multicenter Case-control Study in Chinese populations (LEMCSC).A unified standard was used to recruit patients and collect clinical information.The EpiData 3.1 and SPSS 18 softwares were utilized to input and analyze data respectively.Results One thousand and six patients (87.6％ female) with lupus erythematosus (LE) were included in this analysis,of whom,887 (89.9％ female) had systemic LE (SLE),and 119 (70.6％ female) had isolated cutaneous LE (CLE).The most common involved system in SLE patients was skin (72.7％),followed by joints (69.2％),hematological system (60.8％),kidney (48.5％),serosa (18.2％),and nervous system (5.7％).The appearance of LE-specific skin manifestations was associated with an increased risk of arthritis (odds ratio [OR] =1.612,95％ confidence interval [CI]:1.181-2.200),but with a decreased risk of nephritis (OR =0.218,95％ CI:0.157-0.303) and serositis (OR =0.311,95％ CI:0.218-0.443).The presence of acute CLE (ACLE) lesions was a risk factor for systemic involvement (OR =4.931,95％ CI:3.232-7.524),while that of chronic CLE (CCLE) lesions was a protective factor for systemic involvement (OR =0.355,95％ CI:0.234-0.541).The appearance of LE-nonspecific skin manifestations was closely correlated with the involvement of internal organs in patients with LE.Conclusion This study revealed main characteristics of LE patients in China and the relationship between LE-related skin lesions and internal organ involvement.

OBJECTIVETo explore the mechanism of electroacupuncture at Zusanli (ST 36) on regulation of intestinal inflammatory reaction in rats with acute pancreatitis.

METHODSFifty-four SD rats were randomly divided into a severe acute pancreatitis (SAP) group, an electroacupuncture (EA) group and a sham-operation (SO) group, 18 cases in each group. 3.5% sodium cholate was used to made SAP model by retrograde injecting in cholangiopancreatic duct. After the success of model making, the EA group was treated with EA at bilateral Zusanli (ST 36) for 30 min. The SO group and the SAP group were fixed at the same time for 30 min without treatment. All the rats were killed at 3 h, 6 h and 12 h after modeling in batches. The pathological changes of pancreatic tissue and intestinal epithelium were observed, and the expression of small intestinal occludin protein and nuclear factor kappa-B (NF-kappaB) were detected by immunohistochemical SP method.

RESULTSThe pathologic score and the expression of small intestinal NF-kappaB p65 at 3 h, 6 h and 12 h after modeling in the EA group and the SO group were significantly lower than those in the SAP group (all P < 0.05), and the expression of small intestinal occludin protein in the EA group and the SO group were significantly higher than that in the SAP group (all P < 0.05).

CONCLUSIONElectroacupuncture at Zusanli (ST 36) can alleviate pancreatic injury by reducing the expression of NF-kappaB p65 and enhancing the expression of occludin protein in the intestinal epithelium in the SAP model rats.

BACKGROUND:Compared with hydroxyapatite materials and other nano-hydroxyapatite composites, carbon fiber-reinforced nano-hydroxyapatite/polyamide 66 composites have been significantly improved in the mechanical strength, toughness, elastic modulus and other aspects. It can be used for repairing bone defects of loading parts. OBJECTIVE:To investigate the biocompatibility of carbon fiber-reinforced nano-hydroxyapatite/polyamide 66 composites in bone tissues. METHODS:Eight Bama mini pigs were taken to establish models of thoracic vertebral defects and implanted with carbon fiber-reinforced nano-hydroxyapatite/polyamide 66 composites. At 8, 16 and 24 weeks after implantation,the animals were sacrificed, respectively, for bone mineral density detection and hematoxylin-eosin staining. Blood samples for kidney and liver function tests were taken before and 1 and 8 weeks after implantation. RESULTS AND CONCLUSION: Hematoxylin-eosin staining of bone samples showed that the materials could bond with the bone defect interface without rejection, and could induce osteogenesis of chondrocytes. At 8 weeks after surgery, the broken ends of cancelous bone closed and the composite material was wrapped by granulation tissues. At 16 weeks after surgery, granulation tissues were organized and new bone developed directly from fibroblast cels. The new bone tissues were nearly fused with the end of cancelous bone. At 24 weeks after surgery, new bone tissue became mature lamelar bone, and the end of cancelous bone was connected tightly with the composite material. Bone mineral density of the implanted vertebra showed an increase trend at 8, 16 and 24 weeks after implantation. Over time, the bone mass was increased. The liver and kidney function tests showed that there was no significant difference before and after implantation. It is preliminarily believed that the carbon fiber-reinforced nano-hydroxyapatite/polyamide 66 composite has excelent histocompatibility and bioactivity without hepatic toxicity and nephritic toxicity.

AIM: To study the protective effect and mechanism of panax notoginseng saponinsa(PNS) for dealing with rats with middle cerebral artery ischemia reperfusion(CI/RP). METHODS: To establish the rat middle cerebral artery ischemia/reperfusion model with suture occlusion technique and record the neurologic impairment evaluation score on the basis of Zea Longa method,measured the infarct volume,and the others were detected neuron apoptosis by TUNEL technology and endogenous brain-derived neurotropic factor(BDNF) expression by immunohistochemistry technology. RESULTS: The administration of PNS to rat decreased neurologic impairment,reduced infarct volume,inhibited the neuron apoptosis,and increased endogenous BDNF expression after 24 hours CI/RP. CONCLUSION: Increasing endogenous BDNF expression after CI/RP might be the mechanisms of PNS for achieving neuroprotections.

Objective To investigate the prevalence of subclinical hypothyroidism and its relation to serum total cholesterol (TC),triglyceride (TG) levels and non-alcoholic fatty liver.Methods Serum levels of TC,TG, TSH,TT_3 and TT_4 were determined in 1 602 subjects which were divided into groups by sex and age (20-39,40- 59 and≥60 years).Fatty liver was diagnosed by type B ultrasonography.Restults ( 1 ) Prevalence of subclinical hypothyroidism was 6.6% in this population.(2) The mean levels of serum TC and TG in subclinical hypothyroidism group and normal group showed no significant difference ( both P＞0.05 ).(3) On the whole,the prevalences of subclinical hypothyroidism in hypercholesterolemia group and normal cholesterolemia group showed significant difference (P＜0.01 ).(4) In the three age groups of male and few.ale examinees,the prevalences of subclinical hypothyroidism in hypercholesterulemla group and normal cholesterolemia group showed no significant difference ( all P＞0.05 ).In the multiple regression analysis,TSH level was not related with raised TC level.(5) In the three age groups of male,there was no significant difference between the prevalences of subclinical hypothyroidism in hypertriglyceridemla group and normal triglyceridemia group ( all P＞0.05 ).In female,expect for the elderly group (＞60 years old ),the prevalence of subclinical hypothyroidism was higher in hypertriglyceridemia group than that in normal triglyceridemia.However,in the multiple regression analysis, increased TSH level was positively associated with increased serum TG level ( OR = 1.072,P=0.013 and OR = 1.102,P = 0.03 ).(6) The prevalence of subclinical hypothyroidism in non-alcobolic fatty liver group and normal group showed no significant difference ( P＞0.05 ).In the multiple regression analysis,TSH level was not the independent risk factor of non-alcoholic fatty liver (P＞0.05 ).Conclusion Subclinical hypothyroidism is not asseciated with serum TC level but positively associated with serum TG level.Subclinical hypothyroidism does not apparently increase the prevalence of non-alcoholic fatty liver.
