BACKGROUND: Previous studies demonstrated that recombinant human bone morphogenetic pretein-7 (hBMP-7) can effectively promote the synthesis of extracellular matrix, repair of damaged disc matrix, restore of degenerative disc height. It is hoped that BMP-7 can be used to control and reverse the intervertebral disc degeneration. However, because of the short half-life of recombinant protein and low biological activity, it is difficult to maintain BMP-7 high concentrations on degenerative disc. Gene therapy can prevent these defects effectively.OBJECTIVE: To study the effect of hBMP-7 gene transfeotion on biological activity of primary cultured rabbit nucleus pulposus cells in vitro, to determine the feasibility of hBMP-7 gene which will on gene therapy research of intervertebral disc degeneration,and to provide basis for further study.DESIGN, TIME AND SETTING: A randomized and controlled observation was performed at the Institute of Cardiothoracic Surgery of Changhai Hospital from December 2005 to September 2006.MATERIALS: Six healthy New Zealand white rabbits of either gender, averaging 4 weeks old and weighing 500 g, were used in this study, and Ad-hBMP7 was constructed by the Cardiothoracic Surgery Institute of Changhai Hospital.METHODS: After rabbits sacrifice under aseptic condition, the nucleus pulposus was got. After digested with Pronase, type Ⅱcollagenase and type Ⅱ DNAase (4 hours, 37 "(2), the cells were seeded in the Petri dishes and were kept in the incubator. After 7 days and then twice a week, the media were refreshed. The nucleus pulposus cells were infected by adenovirus integrated with hBMP7 gene. The cells which were transfected by adenovirus vector for Lac-Z gene and which were not transfected were adopted as control.MAIN OUTCOME MEASURES: The expression of hBMP-7 was determined by RTopCR and Western blot. The effect of hBMP-7 on cell proliferation was surveyed by MTT. Furthermore, the effect of hBMP-7 gene on synthesis of proteoglycan and type Ⅱcollagen was detected by modified dimethylmethylene blue method and ELISA, respectively.RESULTS: Gene sequencing and PCR showed that hBMP-7 gene was inserted correctly and no mutation happened. The pdmary cultured rabbit nucleus pulposus cells were identical with those reported in literature. After Ad-hBMP7 transduct into the nucleus pulposus cells, high level of hBMP-7 expression was observed and lasted over 3 weeks. Also hBMP-7 gene can promote cell proliferation and synthesis of proteoglycan and type II collagen with significant difference compared with control groups (P < 0.05).CONCLUSION: hBMP-7 gene mediated by adenovirus can be the target gene for the further study on gene therapy of intervertebral disc degeneration.

OBJECTIVETo evaluate that the effect of formula of removing both phlegm and blood stasis in improving cardiac function of Chinese mini-swine with coronary heart disease of phlegm-stasis cementation syndrome.

METHODTotally 36 Chinese mini-swine were randomly divided to six groups: the normal control group, the model group, the Danlou tablet group, and Tanyu Tonzhi Fang(TYTZ) groups with doses of 2. 0, 1. 0 and 0. 5 g kg-1, with six in each group. Except for the normal control group, all of other groups were fed with high-fat diet for 2 weeks. Interventional balloons are adopted to injure their left anterior descending artery endothelium. After the operation, they were fed with high-fat diet for 8 weeks to prepare the coronary heart disease model of phlegm-stasis cementation syndrome. After the operation, they were administered with drugs for 8 weeks. The changes in the myocardial ischemia were observed. The changes in the cardiac function and structure were detected by cardiac ultrasound and noninvasive hemodynamic method.

RESULTCompared with the normal control group, the model group showed significant increase in myocardial ischemia and SVR and obvious decrease in CO, SV and LCW in noninvasive hemodynamic parameters (P <0.05 or P <0.01). The ultrasonic cardiogram indicated notable decrease in IVSd, LVPWs, EF and FS, and remarkable increase in LVIDs (P<0. 05 orP<0.01). Compared with the model group, TYTZ could reduce the myocardial ischemia, strengthen cardiac function, and improve the abnormal cardiac structure and function induced by ischemia (P <0. 05 or P <0. 01).

CONCLUSIONTYTZ shows a significant effect in improving cardiac function of Chinese mini-swine with coronary heart disease of phlegm-stasis cementation syndrome. The clinical cardiac function detection method could be adopted to correctly evaluate the changes in the post-myocardial ischemia cardiac function, and narrow the gap between clinical application and basic experimental studies.

OBJECTIVETo observe the Chinese medicine constitution types and human leukocyte antigen (HLA)-DQA1 gene polymorphism in patients with hepatitis B (HB) virus infection in Chinese Han population of Zhejiang Province, for exploring the roles of constitution factor in pathogenesis of HB.

METHODSA total of 240 subjects, including 120 biopsy-proven chronic HB (CHB), 60 HB asymptomatic carrier (ASC) and 60 resolved from HBV infection spontaneously (RHBS) were studied. Their Chinese medicine constitution type was judged by Wangqi's classification, and their genotype of HLA-DQA1 was detected by polymerase chain reaction sequence specific primer for comparing the difference between groups in distribution frequency (DF) of constitution types and genes.

RESULTS(1) As compared with the RHBS group, DF of yin-deficiency constitution and phlegm-dampness constitution in the CHB group was significant higher (20.0% vs. 6.7% and 12.5% vs. 1.7%), and that of placid constitution was significant lower (11.7% vs. 31.7%), showing statistical significance between groups (OR = 3.5, 95% CI: 1.16-10.60; OR = 8.4, 95% CI: 1.09-65.42; OR = 0.161, 95% CI: 0.076-0.34; all P < 0.05). (2) As compared with the ASC group, DF of damp-heat constitution was significant higher (24.2% vs. 6.7%, P < 0.05, OR = 4.462, 95% CI: 1.49-13.36), and that of placid constitution was significant lower (11.7% vs. 45.0%, P < 0.01, OR = 0.285, 95% CI: 0.13-0.62) in the CHB group. (3) As compared with RHBS group, DF of HLA-DQA1 * 0201 allele in CHB group was significant higher (38.3% vs. 5.8%, P < 0.01, OR = 10.04, 95% CI: 4.48-22.48); and that of HLA-DQA1 * 0102 allele was significant lower (9.6% vs. 36.7%, P < 0.01, OR = 0.183, 95% CI: 0.10-0.32). (4) As compared with ASC group, DF of HLA-DQA1 * 0201 allele in CHB group was significant higher (38.3% vs. 7.5%, P < 0.01, OR = 7.667, 95% CI: 3.7-15.87), and that of HLA-DQA1 * 0102 allele was significant lower (20.0% vs. 9.6%, P < 0.01, OR = 0.424, 95% CI: 0.23-0.79).

CONCLUSIONBoth Chinese medicine constitution and HLA-DQA1 gene polymorphism show connection with the outcomes of HB virus infection in Chinese Han population, but the real association between them is required for further study.

To analyze the characteristic of urinary protein spectrum in patients with stage III diabetic nephropathy (DN) and its compliance with traditional Chinese medicine (TCM)symptom, for the sake of providing a basis for clarifying the rules of TCM syndrome differentiation in DN. Adopting the traditional epidemiological retrospective method, thirty-eight TCM syndromes and urinary protein with medium or low molecular weight, as well as urinary enzyme, including 24 h urinary protein (Upro), urinary albumin( UAlb), urinary retinal binding protein( URBP), urinary cystatin C (UCysC), urinary N-acetyl-beta-D-glucosaminidase (UNAG), were collected from 108 patients with stage III DN, and a multiple factor regression analysis between them was conducted. As the results, the levels of Upro, UAlb, URBP, UCysC, and UNAG were increased in 108 patients with stage III DN. Qi-Yin deficiency type was the major type. The level of UAlb in patients with Qi-Yin deficiency type was significantly higher than those without Qi-Yin deficiency type (P < 0.05). The elevation of Upro with the factors as swift digestion with rapid hungering, lassitude and lack of strength, weakness of waist and knees was complied, the elevation of UA1b with the factors as dry mouth with desire to drink, the elevation of URBP with the factors as numbness of extremities, shortness of breath, the elevation of UCysC with the factors as clear urine in large amounts, and the elevation of UNAG with the factors as frequent micturition, were complied respectively. In conclusion, for 108 stage III DN patients. The increase in urinary protein spectrum including UAlb, URBP, UCysC, and UNAG is the major characteristic. Shen and Pi are the major organs related to the appearance of urinary protein; Pi-Shen deficiency is the basic pathogenesis. The level of UAlb is taken as one of the objective syndrome factors for Qi-Yin deficiency type. The levels of UNAG and UCysC are possibly the objective syndrome factors for Shen-Qi deficiency type.

OBJECTIVETo observe the correlation between constitution of yin deficiency syndrome (YDS) and polymorphism of HLA-DQA1/treatment response of Peg-lFNalpha therapy in HBeAg positive chronic hepatitis B (CHB) patients, and to explore constitution of Chinese medicine (CM) in response of interferon therapy.

METHODSTotally 120 HBeAg positive CHB patients who were treated with Peg-IFNalpha were enrolled, and assigned to YDS group (59 cases) and non-YDS group (61 cases) according to classification of CM constitutions. All patients were subcutaneously injected with Peg-IFNalpha-2b (1.0 microg/kg body weight) or Peg-IFNalpha-2a (180 microg), once per week. Effective efficacy was primarily judged when complete response (CR) or partial response (PR) was obtained at month 6. Those with CR or PR completed 1 year therapeutic course. HLA-DQA1 gene types were detected by polymerase chain reaction sequence specific primers (PCR-SSP). The distribution difference of CM constitutions in patients with CR or PR and their inter-group HLA-DQA1 allele frequency were compared.

RESULTSDifferent treatment responses of Peg-IFNalpha were observed in CHB patients of two different CM constitutions. The ratio of CR + PR was 61.0% (36/59) in YDS group, obviously lower than that in NYDS group [78.7% (48/61), P < 0. 05]. Patients with CR had a lower allele frequency of HLA-DQA1 * 0501 than those with no-response [14.8% (8/54) vs. 30.6% (22/72)] with statistical difference (P < 0.05). Patients with CR had a higher allele frequency of HLA-DQA1 * 0601 than those with no-response [18.5% (10/54) vs. 5.6% (4/72)] with statistical difference (P < 0.05). The allele frequency of HLA-DQA1 * 0301 was lower in YDS group than in non-YDS group [2. 5% (3/118) vs. 9.8% (12/122)] with statistical difference (P < 0.05). The allele frequency of HLA-DQA1 * 0501 was higher in YDS group than in non-YDS group [33.9% (40/118) vs. 18.9% (23/122)] with statistical difference (P < 0.05). Yet statistical significance was lost after adjustment (Pc > 0.05 for both).

CONCLUSIONSBoth constitutions of CM and HLA-DQA1 gene polymorphism af- fect HBeAg positive CHB patients' response to Peg-INFalpha. Constitutions of YDS and HLA-DQA1 * 0501 was not favorable to response, their association needed to be further studied.

In clinic, some urinary protein makers can dynamically and noninvasively reflect the degree of renal tubular injury in patients with diabetic nephropathy (DN). These urinary biomarkers of tubular damage are broadly divided into two categories. One is newfound, including kidney injury molecule-1 (Kim-1), neutrophil getatinase-associated lipocalin (NGAL), liver-type fatty acid-binding protein (L-FABP) and cystatin C (CysC); the other one is classical, including beta2 microglobulin (beta2-MG), retinal binding protein (RBP) and N-acetyl-beta-D-glucosaminidase (NAG). It is reported that, the increases in urinary protein markers are not only closely related to the damage of tubular epithelial cells in DN patients, but also can be ameliorated by the treatment with Chinese herbal compound preparations or Chinese herbal medicine. Recently, although urinary proteomics are used in the protein separation and identification, the traditional associated detection of urinary protein markers is more practical in clinic. At present, it is possible that the associated detection of urinary biomarkers of glomerular and tubular damages may be a feasible measure to reveal the clinical significance of urinary protein markers in DN patients and the interventional effects of Chinese herbal medicine.

OBJECTIVETo detect the effects of lumbar vertebrae Gucuofeng on the substance P content of hypothalamus and dorsal root ganglia in rat models.

METHODSA hundred and twenty SPF level SD male rats with the weight of 350 to 450 g were randomly divided into rotary fixation group (RF group), simple fixation group (SF group) and sham-operation group (Sham group). The external link fixation system was implanted into the L4-L6 of rats in RF group and SF group; and in RF group, that the L5 spinous process was rotated to the right resulted in L4, L5, L6 spinous process not collinear; in SF group, the external link fixation system was simply implanted and not rotated. The rats of Sham group were not implanted the external link fixation system and only open and suture. The substance P content of hypothalamus and dorsal root ganglia were detected at 1, 4, 8, 12 weeks after operation.

RESULTSSubstance P content of hypothalamus in RF group and SF group was lower than Sham group at 1, 4, 8 weeks after operation (P<0.05). Substance P content of dorsal root ganglia was higher than Sham group at 1, 4, 8, 12 weeks after operation (P<0.05). There was no significant differences in the substance P content of hypothalamus among three groups at 12 weeks after operation (P>0.05).

CONCLUSIONLumbar vertebrae Gucuofeng can inhibit the analgesic activity of substance P in hypothalamus and promote the synthesis and transmission of substance P in dorsal root ganglia, so as to cause or aggravate the pain.
