BACKGROUND:Hip arthroplasty is an effective means currently in repair of femoral neck fractures. With the increased in the amount of surgery, surgery failure rate also has increased. In particular, prosthesis loosening and fracture are very common after replacement.Qiangguyin can promote the formation of osteoblasts, resist osteoporosis, inhibit osteoclast activity, and increase bone density. Drynaria invigorates the kidney, strengthens the bone and tendon and relieves pain, and has bidirectional regulatory effects on promoting bone formation and inhibiting bone resorption.
OBJECTIVE:To investigate effects ofQiangguyin on periprosthetic bone density in patients with femoral neck fracture after hip arthroplasty.
METHODS:96 patients with femoral neck fracture were equaly divided into observation group and control group based on the random number table. Both groups were given selective joint replacement. Patients were implanted with femoral head made by US Stryker Corporation, and fixed with bone cement. After replacement, patients in the control group were treated with calcium D3 tablets and capsules alfacalcidol. On this basis, the treatment group was given theQiangguyin oral drug intervention for a month. Bone density surrounding the prosthesis was observed in both groups. Alkaline phosphatase and tartrate-resistant hydrochloric acid phosphatase activities were detected. Repair effects were compared.
RESULTS AND CONCLUSION:The surgery was successfuly completed in al patients. No infection or loosening of the prosthesis occurred. Ambulation time and healing time were significantly less in the observation group than in the control group (P < 0.05). No significant difference in bone density surrounding the prosthesis was detected between the two groups before medication, and an obvious increased trend was found after medication (P < 0.05). Bone density was significantly higher in the observation group than in the control group after medication (P < 0.05). Serum alkaline phosphatase activity was significantly higher in the two groups after medication, but tartrate-resistant hydrochloric acid phosphatase activity was significantly decreased, which showed significant differences as compared with that before medication (P < 0.05). Simultaneously, significant differences in serum alkaline phosphatase activity and tartrate-resistant hydrochloric acid phosphatase activity were detected between the observation and control groups after medication (P < 0.05). At 6 months after replacement, the excelent and good rate of joint function was significantly higher in the observation group than in the control group (94%, 79%,P < 0.05). These results indicate that Qiangguyin could resist bone resorption and suppress excessive bone turnover, improve bone density around the prosthesis, and restore joint function after hip arthroplasty.

Objective To analyze the incidence of stress hyperglycemia and its influential factors in patients with acute myocardial infarction and cerebral infarction. Methods The case data of 1630 consecutive patients with incipient myocardial infarction without cerebrovascular disease admitted in the department of cardiology and 1338 patients with atherosclerotic acute cerebral infarction without cardiovascular disease admitted in the department of neurology,Xuanwu Hospital,Capital Medical University from January 2009 to December 2012 were analyzed retrospectively. A total of 2048 patients without diabetes mellitus were selected from them,among them 1165 patients were in an acute myocardial infarction group and 883 were in a cerebral infarction group. The fasting blood glucose >7. 8 mmol/L in the next morning after admission was defined as hyperglycemia. Single factor and multifactor logistic regression analyses were used to compare the incidence of stress hyperglycemia and its influential factors of both groups. Results ( 1 ) Of the 1165 patients with myocardial infarction,the incidence of stress hyperglycemia was 17. 2% (n=201);of the 883 patients with cerebral infarction,the incidence of stress hyperglycemia was 5.4% (n=48). There was significant difference between the 2 group (χ2= 65.677;P < 0. 01). (2) Comparing the general information of the patients with stress hyperglycemia (n=249) and those without stress hyperglycemia ( n=1799) of the cardio-cerebrovascular diseases showed that there were significant differences in hyperlipidemia, drinking history, family history of cardio-cerebrovascular diseases, age, heart rate, total cholesterol, low density lipoprotein cholesterol,leukocyte count,blood urea nitrogen,and triacylglycerols between the 2 groups (P<0. 05). (3) Multivariate Logistic analysis showed that heart rate ( OR,1. 013,95%CI 1.002-1.024),leukocyte count (OR,1.109,95%CI 1.508-1.163),and triacylglycerols(OR,1.174, 95%CI 1. 042-1. 322) were the independent risk factors for stress hyperglycemia in myocardial infarction. (4) Systolic blood pressure (OR,1. 019,95% CI 1. 006-1.033) and leukocyte count (OR,1. 132,95%CI 1. 009-1. 268) were the independent risk factors for stress hyperg lycemia in cerebral infarction. Conclusion The incidence of stress hyperglycemia in patients with myocardial infarction is higher than that in patients with cerebral infarction,and the increased leukocyte count is a common independent risk factor for both.

Objective To explore the differential diagnostic significance of clone analysis for multicentric occurrence (MO) and intrahepatic metastasis (IM) in hepatocellular carcinomas (HCCs).Methods Loss of heterozygosity (LOH) and microsatellite instability (MSI) were analyzed by microsatellite polymorphism test and the integration sites of HBV were assessed by Southern blot in each nodule of the HCCs. The clonalities were then compared between each nodule of the same patient and the diagnosis of MO or IM was concluded. Finally, the results based on clonality analysis were compared with those according to clinicopathological and imaging data. Results According to the results of LOH and MSI in 79 nodules and nontumorous tissue from 35 cases of mutiple HCCs, 5 (14.3%)and 29 cases (82.9 %) were divided into MO and IM, respectively. Both MO and IM presented simultaneously in 1 patient (2.9%). The integration sites of HBV could be analyzed in 77 nodules from 34 multiple HCCs. Among them, 6 (17. 6%) and 27 cases (79.4%) were divided into MO and IM, respectively. Both MO and IM presented simultaneously in 1 patient (2.9%). The classification results of microsatellite polymorphism test and HBV integration sites analysis demonstrated a significant positive correlation (rs = 0.909, P＜0.001). Nevertheless, neither the classification of microsatellite polymorphism test nor that of HBV integrate sites analysis was correlated with the discrimination according to clinicopathologic and imaging data (rs=0. 133, P=0. 468, rs =0. 262, P=0. 155, respectively). Recurrence in patients in the MO group occurred significantly later than that in IM cases who were diagnosed by clonality analyses (P=0. 001). Conclusion The clonality analysis based on the results of LOH and MSI or assessments of HBV integrate sites is useful for the differential diagnosis of MO and IM and their treatment and prognosis.

Retinal pigment epithelium ( RPE ) is a vital tissue for the maintenance of photoreceptor function and environment of outer retina, also the predominant cell type of proliferative vitreoretinopathy ( PVR ) . lt is also affected by many diseases of the retina and choroid, including diabetic retinopathy ( DR) , age-related macular degeneration ( AMD ) and retinal pigmentosa ( RP ) . Although of neural origin, the RPE is capable of local repair, and cells may migrate and take on altered characteristics. These findings indicate that RPE-based therapy is a promising option for congenital or degenerate disease of the retina.
