Objective To investigate the general rules and features of drug adverse reaction induced by Reduning injection inorder to provide reference for clinical rational administration.Methods The literatures about the advers reaction induced by Reduning injection published from 2008 -2014 in China were retrieved.The articles were analysed using literature metrology methods.Results 25 articles related to 282 individual cases were retrieved. The adverse reactions were related to sexuality and drug combination.Children were the high risk group.Incidence rate of the adverse reaction of boys was much higher than that of girls.Combination with antibacterials might increase the incidence rate of adverse reaction.The major clincal manifestation was the adverse reaction of dermal system (208 case)and anaphylactic response (36 case).Anaphylactic shock was the serious reaction in clinical (11 case). Conclusion Clinician and pharmacists should understand the rules and characteristic of adverse reaction caused by reduning injection.Using drug must according to the direction in clinical.It must pay more attention to medication mo-nitoring in order to reduce the occurrence of drug adverse reaction.

Objective To study the age-related changes of rat bone histomorphometry and its correlation to other parameters of bone metabolism. Methods Ten female SD rats at the age of 3 months old,9 months old and 15 months old were labeled with tetracycline(30 mg/kg) via abdomen on fourteen and four days before executing. Histomorphometry were performed on L4 and right tibiae. Physical density of left femur and L2 were measured. Anti-compression property of L3 was assayed. Serum levels of calcium and phosphorus and 1,25(OH)_ 2 D_ 3 were determined. Results Compared with the 3-month-old rats,the trabecular bone volume(TBV) of L4 and right tibiae decreased 43.3%( P

Objective To describe postmedial approach to the knee and discuss the main technique using it to repair and reconstruct posterior cruciate ligament (PCL). Methods 24 patients with PCL injury were operated on with the postmedial approach. 13 cases were repaired directly using the technique of pulling out steel wire and 11 cases were reconstructed by semitendinosus. Prone position was adopted in 16 cases and supine position in 8 cases (21 cases had been followed up over six months). Applied anatomy, main techniques and clinical results were evaluated. Results The postmedial approach saved 30～60 minutes compared with the posteior approach, and was not restricted by body posture. Neurovascular structure did not need to be dissected, PCL repair and reconstruction could be finished in one incision.By a six month follow up evaluation, no symptoms of instability occured and they were completely stable on physical examination. Conclusion The postmedial approach is simple, safe, and yields excellent exposure. It's an ideal approach for repair and reconstruction of the PCL.The technique of pulling and steel wire and semitendinosas drawn out "U" shaped pins fixation are essential methods to repair and reconstruct the PCL.

PurposeTo investigate the mechanism of BM210955 (ibandronate, a new bisphosphonate drug manufactured in China)in the prevention of bone loss in vitro. MethodsThe osteoclasts isolated from the long bone of 10-day-old Rabbit were cultured on glass and bone slices in different concentration of BM210955. TRAP(tartrate resistant acid phosphonase) staining for osteoclast and TB( toluidine blue)staining for resorption lacunae were used on bone slices and Fluorescence (orange acridine) staining for apoptosis cell on glass slices was used;Multinucleated( three and more nuclei) TRAP positive cell and Apoptosis cell and Pits were counted. ResultsThe BM210955 decreased the multinucleated cell number by 73% in 10-8 mol/ L;The inhibitory rate of pit formed was correlate to concentration as 31.58%, 76.32% and 87.99% to 10-12, 10-10 and 10-8 mol/L; The apoptosis induction was shown in above 10-8 mol/L, and the apoptosis rate was 62% in 10-4 mol/L. Conclusions Induction of osteoclast apoptosis and decrease of the cell number and inhibition of resorptive ability were the major mechanism for bone loss prevention effect of BM210955 in vitro.

Objective To evaluate the biomechanism of three kinds of internal fixations in treatment of complex tibial plateau fractures. Methods Eighteen human antiseptic cadaver tibial plateau specimens were used to make models of complex tibial plateau fracture (type Ⅵ fractures of Schatzker classification). The models were fixated with a lateral Golf-buttress plate (GP), modified dual plate (a lateral Golf-buttress plate plus a medial five-hole one-third tubular antiglide plate) (DP) or a lateral locking compression plate (LCP) respectively to compare strength, rigidity and stability of different fixation methods. Results The biomechanical strength, rigidity and stability in DP group and LCP group were better than those in GP group (P<0.05), while there was no statistical difference between LCP group and DP group (P>0.05). Conclusions Locking compression plate and modified dual plate are fairly ideal internal fixators for treatment of complex tibial plateau fractures. In the meantime, locking compression plate emphasizes conservation of soft tissues and blood supply, can better meet the requirement of the biological fixation of fracture and is the most ideal internal fixator at present.

Genetic algorithms (GA), a global searching method, is applied to select wavelength variables of near infrared spectroscpy (NIR) for multivariate calibration made by partial least squares (PLS) method. Two application examples of NIR analysis show that this wavelength selection method for PLS modeling not only simplifies and optimizes calibration model but also increases the prediction ability of calibration model. The method is especially adequate for the system where only PLS is difficult to correlate.

Objective To assess the accuracy (ACC),sensitivity (SEN),and specificity (SPE) of dose-volume histogram (DVH) parameters in predicting the radiation pneumonitis (RP) using receiver operating characteristic (ROC) curve.Methods Complete clinical data of 118 non-small cell lung cancer patients treated with three-dimensional conformal and intensity-modulated radiotherapy plus chemotherapy were included.Chi-square and logistic regression were retrospectively applied to analyze the correlations between DVH parameters [relative lung volume received ≥ 5 Gy (V5),10 Gy (V10),13 Gy(V13),20 Gy (V20) and 30 Gy (V30) and mean lung dose (MLD)] and grade 2 (and above) RP defined by the National Cancer Institute Common Terminology Criteria for Adverse Events,version 3.0.ROC curve was adopted to investigate the predictive ACC,SEN and SPE of potential DVH parameters associated with RP.Results Total lungs V5,V10,V13,V20 and MLD were all correlated to the development of RP (x2 =4.786,5.771,6.366,7.367 and 6.945,P ＜ 0.05) according to univariate analysis.However,total lungs V30,patient characteristics (age,sex,KPS,tumor location,pathology) and treatment factors (prescription dose,radiotherapy technique,chemotherapy method and timing) were not contributors to RP.Logistic regression showed that V20 of both lungs remains tight by associated with RP (x2 =10.96,OR =4.16,95％ CI 1.40 ～ 12.36,P ＜0.05),although significant colinearity was found between V20 and other DVH parameters (r =0.767-0.902,P ＜0.05).ROC curve confirmed that V20 of both lungs could act as a predictor for RP (Z =2.038,P ＜ 0.05).The predictive ACC,SEN,and SPE were 0.645 (95％ CI0.498-0.793),0.650 (95％ CI0.408-0.864),and 0.674 (95％ CI0.571-0.765),respectively.However,the positive predictive value was only 28.9％.Conclusions V20 of both lungs was correlated to the development of RP.It could act as a predictor for RP though the predictability is limited.

This study was aimed to preliminarily evaluate the acute toxicity and anti-inflammatory effects of coffee residue extract. The test maximum tolerated dose was applied in mice by gavage to observe the acute toxicity of coffee residue extract. Mice acute inflammation model was induced by xylene and glacial acetic acid. The gavage administration of coffee residue extract (1.00, 2.00, 3.00 g?kg-1, in terms of crude drug) was given 7 days con-tinuously. The ear swelling rate and celiac capillary permeability were measured. The results showed that the ex-tract of coffee residue maximum tolerated dose in mice is 8 . 60 g?kg -1 ( in terms of crude drug ) . The coffee residue extract of 3 . 00 g?kg-1 is able to inhibit ear swelling induced by xylene in mice ( P < 0 . 05 ) and the ex-cessive celiac capillary permeability ( P < 0 . 05 ) . It was concluded that the coffee residue extract have certain an-ti-inflammation activities.

Objective To observe the earlier pathological character and mechanism of radiation osteonecrosis in femoral head, in order to provide evidences for the earlier diagnosis and prevention of radiation osteonecrosis of femoral head. Methods Single femoral head of rats were irradiated singly with 30 Gy of 137 Cs γ-ray. The rats were executed after 2, 6 and 12 weeks, then the femurs were stained with HE and histopatholngical changes were observed by light microscope. The bone marrow mesenchymal stem cells (BMSCs) were cultured after 2 weeks and its proliferation and the colony formation were observed. The rats were endo-perfused with microfili contrast medium 12 weeks later, and the 3-dimensional structure of capillaries by Micro-CT was re-estabhshed to detect the pathological changes of capillaries after irradiation. Result The irradiated femur showed deranged cbondrocyte, decreased osteocyte, shrinking nucleus, increased empty bone lacuna and reduced bone trabocnla (P < 0.05). Micro-CT showed the discontinued small vessels and absence(6.65 %) capillaries in irradiated femur were obviously less than those of the unirradiated (12.3 %)(P < 0.001). The proliferation of BMSCs was slowed, the number of colony in irradiated group (10 %) was less than that of control (21 %) (P < 0.001). Conclusions The preliminary histopathological changes of osteoradionecrosis on femoral head could be increased the empty bone lacuna, and the bone lacuna above 30 % was the sign of the earlier period of osteoradionecrosis. The osteonecrosis of femoral head induced by radiation is not only correlated to the damages to the bone, but also to the damages to BMSCs and capillaries.
