OBJECTIVETo explore effect of Qindan Fuzheng Capsule (QFC) on ultrastructure of cardiomyocytes and hepatocytes injured by high microwave radiation in rats.

METHODSEighteen adult Wistar rats were equally divided into 3 groups in random: rats in Group A were untreated as the normal control, rats in Group B received 6 min microwave radiation (100 mW/cm2 high power) to cause injury of cardiomyocytes and hepatocytes, and Group C received the same radiation but treated with QFC perfusion, 2 mL (equivalent to 4.75 g crude drug) once a day, for 7 successive days, starting from 6 h after radiation. All rats were sacrificed 7 days later, their fresh tissue of heart apex and right lobe of liver were taken and prepared to routine transmission electron microscopy specimen for ultrastructural observation.

RESULTSCompared with Group A, different degrees of ultrastructural changes on nuclei and organelle were observed in Group B and C, but the injury in Group C was significantly milder than that in Group B, showing normal sized cells with good structure approximate to the morphology in Group A.

CONCLUSIONSQFC showed protective effect on microwave radiation injured ultrastructural changes in rats' cardiomyocytes and hepatocyte. Its mechanism was possibly correlated with the suppression of lipid peroxidation and the improvement of metabolism in myocardial and hepatic cells.

OBJECTIVETo observe the protective effect on renal function of Chinese drugs combined with benazepril in patients with diabetic nephropathy (DN).

METHODSAdopting stratified randomized and controlled design, 108 patients with DN were assigned to two groups. Besides the same measures of diet regulation, exercise, education, hypoglycemic and symptomatic treatment applied, benazepril was administered to all patients, and Chinese drugs were given to patients in the treated group additionally. The treatment course was 3 months. The changes before and after treatment of symptoms and signs, 24-h urinary protein (24 hUpro), serum creatinine (SCr), serum creatinine clearance rate (CCr), blood urea nitrogen (BUN), plasma glucose (PG) and blood pressure (BP) were observed, and the time of dialysis therapy initiating was recorded.

RESULTSSCr and 24 hUpro decreased and CCr increased in the treated group significantly (P < 0.01), and the improvement were superior to that in the control group (P < 0.05 or P < 0.01), the renal living time in the treated group was longer than that in the control group, but no significant different in BUN, PG and BP was found between the two groups (P > 0.05).

CONCLUSIONThe treatment program of Chinese drugs combined with benazepril could obviously reduce the levels of SCr and 24 hUpro, increase CCr in patients with DN, and its effect in improving renal function is better than that of using benazepril alone.

Objective To evaluate the efficacy and tolerance of preoperative concurrent chemoradiotherapy in the treatment of locally advanced middle-low rectal cancer.Methods From June 2007 to June 2013,51 untreated patients with histopathologically proven rectal cancer (T3/T4 or N (+))were included in this study.Three-dimensional radiotherapy was delivered to the whole pelvic cavity at 45.0-50.4 Gy/25-28 fractions.Two cycles of chemotherapy with FOLFOX4 or XELOX were given concurrently at weeks 1 and 4 of radiotherapy.Surgery was performed at 4-8 weeks after chemoradiotherapy.Adjuvant chemotherapy with FOLFOX4 or XELOX was given within one month after surgery.The Kaplan-Meier method was used to calculate survival rates,and the log-rank test was used for univariate analysis;the Cox regression model was used for multivariate prognostic analysis.Results Fortynine patients completed the preoperative chemoradiotherapy and surgery.The median follow-up was 2.9 years.The overall sphincter preservation rate was 65％;the overall downstaging rate was 59％.Ten (20.4％) of all patients achieved a pathologic complete response (pCR).Grade ≥3 toxicities occurred in 25％ of all patients,and the overall postoperative complication rate was 31％.The 3-and 5-year sample sizes were 24,12,respectively.The 3-and 5-year overall survival rates were 81％ and 69％,respectively;the 3-and 5-year disease-free survival (DFS) rates were 76％ and 60％,respectively;the 3-and 5-year local recurrence-free survival (LRFS) rates were 78％ and 70％,respectively;the distant metastasis-free survival rates were 82％ and 74％,respectively.The multivariate analysis showed that tumor downstaging was an independent prognostic factor for 5-year DFS and LRFS.Conclusions For locally advanced middle-low rectal cancer,preoperative radiotherapy with concurrent FOLFOX4/XELOX chemotherapy can increase pathologic downstaging rate,pCR rate,and sphincter preservation rate.Patients with tumor downstaging may have a better survival advantage.

Objective To evaluate the prognosis and side-effects of three-dimensional conformal radiotherapy (3 DCRT) and intensity modulated radiotherapy (IMRT) for prostate carcinoma. Methods From 2001 to 2009, 62 patients with prostate carcinoma treated with radiotherapy were included in the retrospective analysis. Among them, 60 patients received IMRT while the other two received 3DCRT. There were 56 patients receiving androgen deprivation therapy before radiotherapy. The median dose was 78 Gy to 95% planning target volume (PTV) of the prostate and seminal vesicles, and the median dose to 95% PTV of the pelvic lymph nodes was 48 Gy. Results The median follow-up was 15.4 months. The 3-and 5-year overall survival (OS) rates were 92% and 83%, with the corresponding biochemical disease-free survival rates of 87% and 69%, and the distant metastasis-free survival (DMFS) rate of 77% and 55%, respectively. Patients with a PSA nadir ≤ 2 ng/ml had a 3-year OS of 94% and DMFS of 88%, compared with 56% and 11% (χ~2 = 16. 39, P < 0.01 for OS ; χ~2 = 28. 87, P < 0. 01 for DMFS) for those with a PSA nadir > 2 ng/ml. The incidence of grade 1 and 2 urinary toxicity was 32% and 0% for acute damage, 10% and 0% for late damage, respectively. The incidence of grade 1 and 2 intestinal toxicity was 19% and 3%. for acute damage, 5% and 3% for late damage, respectively. Conclusions Radiation therapy for patients with prostate carcinoma shows satisfactory outcomes with a good toleration. Monitor of PSA after radiotherapy has benefit for prognosis evaluation.

Background Epidemiological investigation in human has been conclusive. In postmenopausal women,the incidence of cataract is higher than men at the same age. In addition,hormone replacement therapy may protect against the development of cataract. However,this role of androgen is not clear. Objective This study was to explore the effects of estrogen and androgen on anti-oxidative ability of lens after ovariectomy. Methods Fifty-six three-month-old clean female Wistar rats were randomly divided into normal control group,sham operation group, castration group,estrogen eyedrops group;estrogen injection group;androgen eyedrops group;androgen injection group and 8 rats for each. Ovariectomy was performed in the rats of castration group and gonadal hormone application group, and estradiol benzoate solution or testosterone propionate solution were utilized topically or systemly in 5 months after ovariectomy for 6 weeks respectively. Only abdominal cut was curried out in sham operation group. The lenses of rats were examined weekly under the slit lamp. The serum estrogen and androgen levels of rats were detected before,after operation and 6 weeks following the administration of gonadal hormone. The contents of superoxide dismutase( SOD) , glutathione( GSH) ,malondialdehyde( MDA) and water-soluble protein ( WSP) in rat lens homogenate were detected at the end of the experiment. Utilization of animals complied with the Regulation for the Administration of Affair Concerning Experimental Animals by State Science and Technology Commission. Results No opacity of lenses was found during the experiment duration in various groups. The serum estradiol levels of rats in sham group were insignificantly different from normal groups in various time points( P>0. 05). The evident decline of serum estradiol was detected in the rats of castration group and gonadal hormone application groups compared with sham group in 5 months after operation( all P<0. 01). However,at the sixth weeks after the system use of estradiol or testosterone,the serum estradiol levels were significantly higher than the castration group and topical application groups of gonadal hormone(P<0. 01). The contents of SOD,GSH and WSP in lenses were considerably increased,but the MDA level in lenses was decreased after system use of estrogen ( P<0. 01). The activity of SOD and GSH were lower after system use of testosterone in comparison with castration rats ( P < 0. 05 ). Conclusion Estrogen can protect lens against oxidation damage. However, androgen, to a certain extent, may contribute to the development of oxidative damage in OVX female rats.

BACKGROUND: Icariin has a broad prospect for promoting cell proliferation. Differentiation direction of periosteal cells is uncertain, but the cells are easy to be induced by ultrasound, oxygen or bone morphogenetic protein 7 (BMP7). Periosteal cells have been applied in bone tissue engineering; however, icariin effects on the proliferation and differentiation of periosteal cells is little reported.OBJECTIVE: To investigate the effect of icariin on the proliferation and differentiation of human periosteal cells, thus providing theoretical basis for icariin applied in bone tissue engineering. METHODS:The human periosteum was obtained and the primary cells were isolated in vitro.After culture and expansion,periosteal cells were cultured in 24-well plates, and induced by 0.001, 0.01 and 0.1 mg/L icariin and 50 μg/L BMP7, respectively. The corresponding avsorbance values of different groups were detected. The levels of alkaline phosphatase and calcium nodules in periosteal cells were measured at 1, 3, 5 and 7 days, and the mRNA levels of osteocalcin, osteopontin and Runx2 were detected at 3, 5 and 7 days. RESULTS AND CONCLUSION: The periosteal cells proliferated well after induction with icariin, and could proliferate well in different concentrations of icariin and the positive control group (P < 0.05). Compared with the control group, the periosteal cells induced by icariin were able to produce more alkaline phosphatase and calcium nodules (P < 0.05). The mRNA expression of osteocalcin, osteopontin and Runx2 in periosteal cells could be up-regulated by icariin (P < 0.05). These findings imply that icariin can promote proliferation and differentiate of periosteal cells into osteoblasts, and it can be used as an inducer for the preparation of seed cells in bone tissue engineering.

BACKGROUND: Although icariin has a clear role in inducing differentiation of bone marrow stromal cells, no studies have reported on its use in proliferation of periosteal cells in animal experiments. Three-dimensional polycaprolactone scaffold is a new scaffold, and it has the characteristics of biodegradability, proper pore size, and good histocompatibility. OBJECTIVE: To investigate the effect of icariin on the proliferation of periosteal cells, to construct periosteal cells and three-dimensional scaffold composite tissue-engineered bone and study its therapeutic effect on radical defects in rabbits, so as to provide a new way for the treatment of bone defects . METHODS: The mandibular periosteum was obtained from the rabbit and the primary cells were obtained by tissue explant method. The passage 3 cells were planted on 24-well plates. In experimental group, icariin at 10-4, 10-3and 10-2mol/L were added into the corresponding cell culture wells; equal volume of PBS was added to control group; positive control group was treated with 10 μg/L basic fibroblast growth factor. The cell proliferation in each group was measured by MTT method on the 2nd, 4th, 6thand 8thdays, respectively. The three-dimensional polycaprolactone scaffolds,10-2mol/L icariin and 107/L periosteum cells were placed in cell culture plates and cultured in vitro to construct the cell-scaffold complex. After the rabbit radical defect model was established, the model rabbits were randomized into three groups (n=15 per group), followed by implanted with scaffold complex (experimental group), polycaprolactone scaffold (polycaprolactone group) or nothing (control group). Pathological sections were taken at the 2nd, 4thand 8thweeks respectively for hematoxylin-eosin staining to observe the bone and count the number of osteoblasts. The X-ray films of the radius were obtained at the 4thweek. RESULTS AND CONCLUSION: (1) The proliferation of periosteal cells induced by different concentrations of icariin, especially 10-2mol/L icariin, was better than that in the control group (P < 0.05), Therefore, the optimal concentration of icariin was 10-2mol/L. (2) At 4 weeks after transplantation, in the experimental group, there were more osterocytes and less microvessels; in the polycaprolactone group, there were more new vessels, less woven newly born bone and osterocytes; in the control group, the defect region was filled with more granulation tissue and less osterocytes. At the 8thweek, complete healing in the defect region was observed in the cell-scaffold complex group, while partial healing in the polycaprolactone scaffold group. In the control group, however, fibroblasts and scar tissues were visible in the defect region, with presence of closed medullary cavity and nonunion. The number of osteocytes in the experimental group was significantly higher than that in the other two groups (P < 0.05). X-ray examination at the 4thweek showed that the defect region in the experimental group achieved healing;in the polycaprolactone group, the callus formed and defect region connected partly; and there was a clear gap in the defect region of the control group. Our findings indicate that icariin at different concentrations can promote the proliferation of periosteal cells and the concentration of 10-2mol/L has the greatest role. Icariin can induce proliferation of periosteal cells in the three-dimensional polycaprolactone scaffold, which contributes to bone repair.

OBJECTIVETo observe the influence of Pilose antler polypeptide on the glycosaminoglycan and type II collagen in the articular cartilage in experimental knee osteoarthritis.

METHODSTotally 64 New Zealand white rabbits of 6 months old were randomly divided into 2 groups:normal group (n = 8) and model group (n = 56). Model group was surgically induced into osteoarthritis model by method of Hulth. After successful modeling, the rabbits of model group were further divided into 2 groups: Pilose antler polypeptide-treatment group and control group, 24 rabbits in each group. Pilose antler polypeptide-treatment group received 0.5 ml intra-articular injection of Pilose antler polypeptide dilution liquid once in per 2 days for 30 days, while control group received 0.5 ml intra-articular injection of physiological saline. On days 7, 15 and 30 after intervention, articular cartilage samples were collected respectively. The content of glycosaminoglycan in articular cartilage was observed by toluidine blue staining and the expression of type II collagen in cartilage matrix was detected by immunohistochemical staining.

RESULTSAlong with the prolonging of time, the content of glycosaminoglycan and type II collagen in cartilage matrix of the Pilose antler polypeptide-treatment group and control group decreased gradually. On days 7, 15 and 30 after intervention, integrated optical density of the type II collagen positive area in cartilage matrix of the Pilose antler polypeptide-treatment group were (312.06 +/- 14.12), (273.31 +/- 12.42) and (248.34 +/- 10.41), which had statistically significant differences. Integrated optical density of the type II collagen positive area in cartilage matrix of the control group were (253.47 +/- 15.53), (215.67 +/- 9.72) and (160.01 +/- 13.23), which had statistically significant differences. At the same period, integrated optical density of the type II collagen positive area in cartilage matrix of the Pilose antler polypeptide-treatment group was higher than that of control group, which had statistically significant difference.

CONCLUSIONPilose antler polypeptide can inhibit reduction of the glycosaminoglycan and type II collagen in cartilage matrix and delay the degeneration of articular cartilage.
