Objective: To observe the effect of Angong Niuhuang Bolus on prognosis of diffuse axonal injury (DAI), and to explore awaking and body-temperature-reducing actions of Angong Niuhuang Bolus in the patient of DAI. Methods: 30 cases of DAI were treated by routine western medicine therapy plus Angong Niuhuang Bolus as treatment group, and other 30 of DAI were treated by only routine western medicine therapy as control group. Their prognosis was estimated and analyzed by Glasgow Coma Scale(GCS)and Glasgow Outcome Scale(GOS)and mortality. Results:The total effective rate of 80% in the treatment group was significantly better than 56. 7% in the control group(P

Objective To develop a method to determine Pb and Cd in Qingkailing Injection by graphite furnace atomic absorption spectrometry, and search their source. Methods The samples, digested via microwave, were determined the contents of Pb and Cd by graphite furnace atomic absorption spectrometry in raw material, intermediate and finished product of Qingkailing Injection. Results The standard curve of Pb was Y=0.007 3X+0.011 6, and Cd was Y=0.056 7X+0.060 4. The regression equation of Pb and Cd was 97.0% and 95.6%, respectively. Content determination of Pb and Cd in Qingkailing Injection revealed that Pb and Cd in finished product came from raw materials. Conclusion The method is rapid, high sensitive and accurate, and can be applied to the inspection of Pb and Cd in Qingkailing Injection.

To evaluate the validity of osteoarthritis model induced by bilateral ovariectomy in guinea pig, 32-month-old female guinea pigs were randomly divided into two groups: a sham operation group (control group) and an ovariectomized group (OVX group). The animals were killed 6 or 12 weeks after the operation and the degeneration of the knees were assessed microscopically and histologically by scanning electron microscope (SEM), transmission electron microscope (TEM) and light microscope. The serum levels of estrogen and gestone were detected by immune contest assay. The scoring of articular cartilage histopathology of tibial plateau was performed by histopathological examination. The blood serum levels of estrogen and gestone were decreased significantly in the OVX group as compared with the control group 6 or 12 weeks after the operation. Joint cartilage degeneration as detected by SEM and TEM could be found at the 6th week, but severe degenerative lesions were observed at the 12th week in the OVX group as compared with the control group (P<0.01). The histopathological score of articular cartilage in tibial plateau in OVX group was higher than that of control group, which was coincident with the changes of estrogen and the ultrastructure (P<0.01). The findings suggested that bilateral ovariectomy in guinea pig can induce the severe osteoarthritis that is similar to the aging-induced OA in human. Therefore, the model of the osteoarthritis by bilateral ovariectomy in guinea pig in this study is valid.

Objective To investigate the stress distribution of the femur after cemented prosthetic replacement in aged patients with comminuted intertrochanteric fracture and to analyze the difference of stress distribution between cemented long and short stem prosthesises.Methods A volunteer's left femur image data was obtained by spiral CT tomography.Then,the three-dimensional model of the femur was reconstructed with Mimics and Unigraphics modeling softwares.Based on the above analysis,we established three-dimensional modles of comminuted intertrochanteric fracture,long stem and short stem prothesises,and mantle layer of cement.Finally,we established the three-dimensional finite element model of these materials with software ABAQUS6.5,and carried out finite element analysis to the model in biomechanics.Results The stress disrilbution of the femur after cemented long and short stem prosthetic replacement didn't change significantly.The stress distribution of short stem between cement and prothetic stem were in the correlative area of distal end of the prothesis,and the lateral peak value was 21.3 MPa which exceeds the fatigue strength of bone cement;However,that of long stem were in the middle of medial interface and in the distal end of bilateral interface.There was no significant stress concentration zone in the mantle layer of cement which was used to reconstruct calcar femorale.Conclusion The stress distribution of the femur didn't change significantly after treating comminuted intertrochanteric fracture of aged patients with cemented long and short stem prosthesises.The cemented long stem prosthesises may be more suitable to treat these patients for its lower loosening probability.

Four different strains of Leptospira were subcultured in CGM in contrast with in Korthof medium for three years. The antigenic components of these Leptospira grown in the two medium were analysed by the methods of MAT, CIE and SDS-PAGE. The results showed that:1, the antigenic components of Leptospira were very complex and had more than twenty bands stained with Coomassie brilIiant blue in SDS-FAGE pattern; 2. the antigenicity of Leptospira subcultured in CGM for many generations was relative stability and the same as that in Korthof medium.

Objective:A study was conducted to determine the expression of acetyl-coa carboxylase product of phosphorylation (P-ACC) and an enzyme called cyclooxygenase 2 (COX-2) in non-small cell lung cancer (NSCLC) tissue, as well as the relationship and correlations between tumor size, lymph node metastasis, clinical stage, and pathological type. Methods: Sixty-two patients with NSCLC lung cancer tissues were included in the patient group, whereas 20 patients who underwent lobectomy for other reasons and had normal lung tissues were included in the control group. Immunohistochemical streptavidin peroxidase method was used to detect the expression of P-ACC and COX-2 in lung cancer and normal lung tissues. Results:The positive expressions of P-ACC and COX-2 in NSCLC lung cancer and normal lung tissues were significantly different (P<0.05). In NSCLC tissues, the positive expression of P-ACC was significantly associated with tumor size (P<0.05), but was not significantly associated with lymph node metastasis, clinical stage, and pathological type. We found no correlation between the positive expression of COX-2 and tumor size, lymph node metasta-sis, clinical stage and pathological type. Further analysis revealed that the positive expression of P-ACC and COX-2 in NSCLC was sig-nificantly and negatively correlated (r=-2.37, P=0.032). Conclusion:The positive expression of COX-2 in NSCLC greatly increased compared with that of P-ACC, and a significantly negative correlation was observed between them. We propose that the positive expres-sion of P-ACC reduction may activate the positive expression of COX-2 and promote the occurrence, development, invasion, and metas-tasis of NSCLC.

OBJECTIVETo observe the regulative effects of the acupuncture on glucose and lipid metabolism disorder in the patients of metabolic syndrome.

METHODSSeventy-six patients of metabolic syndrome were rando-mized into an acupuncture plus western medicine group (37 cases) and a western medicine group (39 cases). In the western medicine group, the conventional western medication was used for 40 days. In the acupuncture plus western medicine group, the acupuncture was combined on the basis of the treatment as the western medicine group, the acupoints were Danzhong (CV 17), Zhongwan (CV 12), Tianshu (ST 25), etc. Ten treatments were as one session. There were 3 to 5 days of intervals between the sessions and totally 30 treatments were required. The body mass index (BMI), blood lipid, blood glucose, and comprehensive therapeutic effects were compared before and after treatment in the two groups.

RESULTSBefore and after treatment, the differences were all significant in BMI, triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), fasting blood glucose (FBG), plasma glucose of 2 hours post glucose-load (2 hPG), fasting insulin (FINS) and insulin resistance index (HOMA-IR) (all<0.05) in the acupuncture plus western medicine group, and the results after treatment were superior to those before treatment; the difference was not significant in BMI (>0.05) and those were all significant statistically in TG, TC, LDL-C, HDL-C, FBG, 2 hPG, FINS, HOMA-IR (all<0.05) in the western medicine group, and the results after treatment were superior to those before treatment. After treatment, in comparison of the two groups, the results in the acupuncture plus western medicine group were better than those in the western medicine group. The differences were all signif-icant sta-tistically in BMI, TG, TC, LDL-C, HDL-C, FBG, 2 hPG, FINS, HOMA-IR (all<0.05).

CONCLUSIONSOn the basis of the conventional western medicine, the acupuncture relieves apparently the clinical symptoms and rectifies glucose and lipid metabolism disorder in the patients of metabolic syndrome.
