Objective To observe the level changes of serum interleukin-18(IL-18) and tumor necrosis factor-?(TNF-?) in alcohol liver disease of rats.Methods The dose of 56% alcohol [5～9 g/(kg?d)] was administeredvia gastrolavage once daily for 12 weeks in ALD model rats.The control rats were grven the same volume of saline.The rats were killed at the end of 4,8,12W.The pathological changes of liver were observed under light microscope after HE staining,and the levels of IL-18 and TNF-? in serum was determined with ELISA.Results The tissues of model rats showed various changes of chronic alcohol liver disease at the end of 4,8,12W,such as: fatty degeneration,inflammatory changes and fibrosis.The levels of ALT and AST in models were obviously higher than those of the controls(P

Objective To understand the proliferation of algae in Hanjiang River during low water period. Methods Identification and counting of algae was carried out in water samples collected from the locations with a depths of 0.5 m, 1.0 m and 1.5 m under the surface of water in the section of Zongguan water plant of Hanjiang River during low water period. Results The temperature of water of Hanjiang River was 19 ℃. The dominant algae was Bacillariophyta with a constetuent ratio of 72.38%, others were Chlorophyta (13.35%), Cryptophyta (9.68%), Cyanophyta (4.12%). The algal count was 1.8?10 4/L. Out countless diatom shells were found also. Conclusion The water pollution by algae of water of Hanjiang River during low water period should be paid more attention to, and its monitoring should be strengthened.

Objective To evaluate the influence of partial parenteral nutrition on serum osmotic pressure,blood glucose,(biochemistry),bilirubin metabolism,immune function,growth and development of premature infants.Methods Seventy premature infants were randomly divided into control group and study group.On the base of enteral feeding,study group were offered parenteral nutrition, while the control group were supplied 10% glucose, fluid and electrolytes. Simultaneously, relevant indices were measured in 2 groups.Results 1.There were no significant difference in serum osmotic pressure,blood glucose and biochemistry before and after parenteral nutrition. 2.There were no significant difference in emerging and lasting time of jaundice between 2 groups.3.Serum IgG,IgA,IgM,C_3,CD4 and CD4/CD8 in study group were significantly higher than those in control group. 4.In study group the time of hospitalization and birth-weight regain were significantly shorter than those in control group.Conclusions There is no significant influence on serum osmotic pressure,blood glucose, biochemistry and bilirubin metabolism during partial parenteral nutrition. Parenteral nutrition may help gain weight, shorten the time of hospitalization, and improve immunological function of neonates.

Objective To analyze Vitamin D nutritional status of children and their height growth relationship in Wanzhou dis-trict of Chongqing .Methods Electrochemiluminescence immunoassay method was used to detect serum 25 hydroxyvitamin D [25 (OH) D]concentrations in 2 727 Children from Wanzhou district of Chongqing ,analyzing the correlation of Vitamin D and children age ,gender ,height ,parental height and other factors .Results There was significant difference in serum level of 25(OH) D among different age groups(P<0 .01) ,there was significant difference between boys and girls among the same age groups of 5 months ,6 months ,4 years old ,5 years old .Children′s height consistented with the national average 4 -6 years ago in Wanzhou District ,but Since then ,gradually felled behind .After adjustment for age ,sex ,parental height ,measured seasonal and other factors ,serum 25 (OH) D concentration was positively correlated with height (r=0 .462 5 ,P<0 .01) .Conclusion 25(OH)D levels were closely re-lated with the development of children′s height .Thus ,children generally poor 25(OH)D nutritional status in Wanzhou district should arouse the attention of parents and clinicians .

ObjectiveTo evaluate the effects of intense pulse light (OPT) on the facial pore widening of different parts.MethodsThirty six women with widened pores were enrolled,and treated by OPT for 6 times.All the cases were taken photos before and after treatment.The pores of cheek,nasal ala and nasal tip were graded by using the photographic scale,and the improvement after treatment compared with that before.ResultsThe cheek,nasal ala and nasal tip pores evidently diminished (P＜0.01).The improvement rate of cheek pores was higher than that of nasal ala and nasal tip (P＜0.01),but that between the latter two was not different (P＞0.05)).ConclusionsThe cheek pore widening diminishes more significantly than nasal ala and nasal tip treated with OPT.

Limb rehabilitation is one of the key issues for improving the quality of life in patients with stroke. Studies have demonstrated that the retention and recovery of active movement of hemiplegic limb have predictive value for the prognosis in acute stroke. The responsible lesion sites and rehabilitation training in the acute phase may be an important factor in influencing the recovery of active movement ability of hemiplegie upper limb. However, there is still lack of a large, multi-center study, and further related studies are needed.

Objective To develop and perfect the infusion function of field operation stretcher by attaching infusion support.Methods The linking structure was developed for conveniently mounting infusion support to field operation stretcher so as to pack them off together.Results The infusion support is simple to operate,reasonable in structure,convenient to put off,and suitable for various field operation stretcher.Conclusion The field rescue,especially the quality of casualty transports,is improved.The manpower and material resources needed in on-site rescue are greatly reduced.[Chinese Medical Equipment Journal,2008,29(2):68]

0.05).The cure rate was 100%and parasite recrudescence rate was zero in both groups,the difference being insignificant.The incidence of adverse reaction was lower in Artekin group.【Conclusion】Artecom and Artekin have similar therapeutic effect on uncomplicated falciparum malaria,but Artekin without trimethoprim has lower adverse reactions,thus it is recommended for clinical use.

Objective To establish an experimental autoimmune encephalomyelitis (EAE) model in Wistar rats with myelin basic protein fragment (MBP69-85) and observe its pathological changes. Methods MBP69-85 dissolved in normal saline was mixed with complete Freund's adjuvant (CFA) (including 6 mg bacille Calmette Guerin) to prepare the encephalitogenic emulsion. Ten out of 70 Wistar rats were chosen as a control group, the others were divided equally into group A,B,C according to the difference of the encephalitogenic emulsion. Rats in group A were immunized with 50 μg MBP69-85 +CFA (including 6 mg BCG). Rats in group B were immunized with 25 μg MBP69-85+CFA (including 6 mg BCG). Rats in group C were immunized with 25 μg MBP69-85+CFA (including 12 mg BCG). The pathological changes of brain and spinal cord tissues were examined by light microscopy after HE staining and immunohistochemistry of MBP and NF. Results Some of the Wistar rats immunized with 50 μg MBP69-85 showed disorder at 12～16 days after immunization. The clinical symptoms included tail acratia or paralysis of tail and limbs, head tilt, etc. and the mean score was 2.38±1.89. There were infiltration of inflammatory cells inside nervous tissue and perivascular cuffings in HE stained sections. The immunohistochemistry of MBP and NF showed demyelination in the white matter and axon injury. Conclusion To some extent, the establishment of EAE depends on the dose of the immunizing antigen. The BCG in CFA was not the major cause of morbility of the rats. The EAE model induced with MBP69-85 in Wistar rats, showing typical clinical symptoms and pathological changes of multiple sclerosis, is a reliable animal model for the study of pathogenesis and treatment of multiple sclerosis.
