Objective To analyse effect of tripterygium glycosides on serum ion and β2-GPI/ox-LDL in patients with IgA nephropathy. Methods 54 patients who were diagnosed with primary IgA nephropathy in our hospital were collected.All patients were randomly divided into experimental group and control group, 27 cases in each group.Control group was given conventional Benazepri1 Hydrochloride Tablets 10 mg, 1 times per day orally;given Dipyridamole Tablets 50 mg, 3 times per day orally, patients in experimental group were given tripterygium glycosides 20 mg on the basis of control group treatment orally,3 times per day.All the patients were treated for 6 month.After the treatment, the serum levels of Ca,P,β2-GPI/ox-LDL and renal function related index were detected in all patients.Results Compared with control group post-treatment, the serum level of Ca was higher(P<0.05); and the serum level of P was lower in experimental group(P<0.05); the serum level of β2-GPI/ox-LDL was lower in experimental group(P<0.05);the serum levels of Scr and BUN were lower in experimental group(P<0.05).Conclusion The tripterygium glycosides can significantly reduce the serum levels of P,β2-GPI/ox-LDL,Scr and BUN,and increase serum Ca level in patients with IgA nephropathy, improve renal function.

Objective To observe the effect of shuanghuang liquid on bum wound healing. Meth-ods 120 cases of patients with moderate bums adopted shuanghuang liquid (the treatment group) and gentamyein (the control group) for wound dressing change, wound pain and wound healing effect were com-pared between the two groups. Results The two groups showed difference in reducing wound pain and shortening time of wound healing. Conclusions Shuanghuang liquid was superior to gentamycin in wound healing and wounds pain.

BACKGROUND: In recent years, acel ular human cadaveric dermis has been applied for repairing dermal defects and fil ing soft tissues, but this repair material is expensive and difficult to obtain. OBJECTIVE: To explore the repair effect of tissue-engineered acel ular dermis on wound healing of skin ulcer. METHODS: Sprague-Dawley rats were randomly divided into autologous reticular dermis and acel ular dermis groups. The tissue-engineered acel ular dermis was prepared by hypotonic solution, 2.5 g/L trypsin, 0.5% Triton X-100 and PBS solution, and in the meanwhile, a rat model of skin ulcer was established. Then, autologous skin graft and tissue-engineered acel ular dermis were transplanted into the autologous reticular dermis group and acel ular dermal group, respectively. Subsequently, comparative study about the repair effect and relative mechanism between two groups was performed. RESULTS AND CONCLUSION: The tissue-engineered acel ular dermis showed a white and grainy shape at room temperature. And hematoxylin-eosin staining showed that: the internal structure of tissue-engineered acel ular dermis exhibited a dendritic distribution, and the gap between col agen fiber bundles was relatively large. At 2, 3, 4 and 8 weeks after dermal transplantation, the survival rate of skin graft in the acel ular dermis group was significantly higher than that in the autologous reticular dermis group (P < 0.05). And the wound contraction rate in the acel ular dermis group was significantly higher than that of the autologous reticular dermis group at 3, 4 and 8 weeks after dermal transplantation (P < 0.05). In addition, the average diameter and clearance rate of col agen fibers in the normal skin around wound in the acel ular dermis group were significantly higher than those of autologous reticular dermis group (P < 0.05). To conclude, it is relatively simple to prepare tissue-engineered acel ular dermis under mild conditions, and the prepared tissue-engineered acel ular dermis presents a regular shape. Moreover, this acel ular dermis achieves desired outcomes in repairing dermal defects, which can promote wound healing by reducing the intradermal DNA residual and significantly improving some biomechanical properties in vivo.

[Objective]To prepare a new porous composite artificial bone substitute and evaluate its properties.[Method]Thermally induced phase separation was adopted to prepare the artificial bone made from oyster shell powder and PLLA which were proportionally mixed and its properties as porosity rate,pore size and mechanical strength were assessed.Meanwhile the related variation parameters were examined every 2 weeks in a course of 14 weeks after the slices of CAB and pure PLLA were immersed in NS of 37℃ in vitro,the results of which were compared in statistics.[Result]The average porosity rate of artifical bone with TIPS method was 85.1% and pore sizes ranged 100-300 ?m under the SEM,with better pore connectivity and regulation shape.The average compressive strength was 2.12 MPa.As the immersion prolonged,the regular variation was observed about the mass loss of CAB and the pH alteration of solution,there was statistically difference in the indexes between the two groups(P﹤0.05).[Conclusion]The porosity rate,pore size,mechanical strength and degradation performance in vitro of the artifical bone made by TIPS method can satisfy the requirement of bone substitute.

To establish a xenografted tumor strain of human osteosarcoma in nude mice and a homologous cell line, the osteosarcoma speciments from patients were inoculated into the subcutaneous tissue of nude mice. After the transplanted tumor had grown to about 2cm in diameter, the tumor tissue was cultured in vitro and the continuously growing cells were analyzed by morphology, histochemistry, immunohistochemical straining, cell cycling analysis ,chromosome analysis and heterotransplantation. A newly established cell line designated PL 1 was thus obtained in this laboratory in continuous culture for over 100 passages. Under light and electron microscopes, the cells assumed the main characters of malignancy.Morphological observation, histochemistry analysis and BMP immunohisto chemical straining showed that they had the features of osteosarcoma.The cell cycle analysis showed 53 2% of the cells were in G 1. This cell line could produce ALP and BMP.Chromosome analysis confirmed that they had retained a karyotype of human cancer cells and a hypotriploid feature with a mode number of around 64～66.The tumor formation rate after heterotransplantation was 100%. It had lung metastasis characters. Therefore, PL 1 cell line derived from the xenograft in nude mice has been established and maintained for over 9 months trough 100 passages, and this cell line can provide material and model for further investigation of human osteosarcoma.

OBJECTIVE:To establish the method for assaying bacterial endotoxins in levofloxacin hydrochloride injec?tion.METHODS:The interference test of3batches of levofloxacin hydrochloride injection with2kinds of limulus test agent was studied.RESULTS:The interference between the samples and limulus test agents was eliminable(below1.0mg/ml).The detection results were up to standard.CONCLUSION:The bacterial endotoxin in the sample can be examined by limulus test instead of pyrogen test in rabbits.
