Objective To discuss the effect of operations for comminuted patella fractures with cable cerclage and revised tension band. Method Retrospective study of clinical effects of 120 patella fractures cases which used cable(cable group,55 cases) or NT-PC (NT-PC group,65 cases) to internal fix.Results At 10 to 38 ( 19.50 ± 1.15 ) months follow-up, all cured well in 12 weeks. Compared with the operative time, the amount of blood loss, length of hospitalization, time for cure, the incidence of complications,there were no significant differences between two groups (P ＞ 0.05 ). The B (o)stman score of cable group [(27.0 ±0.2) scores] was better than that of NT-PC group [(25.1 ±0.6) scores](P＜0.05). Conclusion Using cable cerclage and revised tension band to internal fix for comminuted patella fractures,the operations are facile and the results are satisfactory.

The study is to report the establishment of a method of screening the antitumor compounds based on the dynamic bio-response profile of cells to make up for the shortages of conventional end-point tests such as tedious operation and low sensitivity. Based on the principle of electric impedance of cells, the real-time cell electronic sensing (RT-CES) system was used to monitor the effect of epirubicin (EPI), cisplatinum (DDP) and carboplatin (CBP) on the growth of HepG2 cells, with the cell index (CI), half maximal inhibitory concentration (IC50) and detachment curve as evaluation indexes. Meanwhile, cell counting kit-8 (CCK-8) and microscopy were applied for verification. The results showed that CI curve could sensitively real-time profile the inhibitory effect of model drugs on HepG2 cells. The IC50 of EPI, DDP and CBP were 0.53 +/- 0.04, 9.79 +/- 0.26 and 597.00 +/- 3.79 microg x mL(-1), respectively. What's more, the significant differences of detachment curves of the three drugs indicated that their functional mechanisms might be different, this is consistent with the literature. The RT-CES system with non-invasive, label-free and real-time characteristics could be used to monitor the bio-response profile of the three drugs to HepG2 cells, allowing to qualitatively and quantitatively distinguish the antitumor activities of the three drugs, and could be a complementary method for the present screening of antitumor compounds.

This study aims at trying to establish a novel method of sterility test for injections based on biothermodynamics, in order to overcome the deficiencies of routine sterility tests such as long detecting cycle, low sensitivity and prone to misjudgments. A biothermodynamics method was adopted to rapidly detect the microorganism contamination of injections by monitoring the heat metabolism during the growth of microbe. The growth rate equal to or greater than zero and the heat power difference of P(i) and P(0) with three folds higher than the noise of baseline were chosen as indexes to study the heat change rule of microbe. In this way, the effectiveness of the new method to detect strains required by conventional sterility test or in injection samples was also investigated. Results showed that the Gram-positive bacteria, Gram-negative bacteria and fungi demanded by sterility testing methodology could be detected by biothermodynamics method within 10 hours, with the sensitivity lower than 100 CFU x mL(-1). Meanwhile, this method was successfully applied to the sterility test of Compound Yinchen injection (FFYC), Shuanghuanglian powder injection (SHL) and Compound Triamcinolone injection (TAND) which were sterilized with different degrees. Therefore, the biothermodynamics method, with advantages of fast detection and high sensitivity, could be a complementary solution for conventional sterility tests.

The dosage-efficacy/toxicity relationship of the 50% alcohol extracts of Polygonum multiflorum was comparatively investigated on either normal or CCl4-induced chronic liver injury rats, by determining the general condition, serum biochemical indices and liver histopathology, coupled with the factor analysis. The dosages were 10 and 20 g raw materials per kg body weight. Compared with the normal control group, the normal high dose group showed significant increases of the serum alanine transaminase (ALT), total bilirubin (TBIL), high mobility group box 1 (HMGB-1) and interleukin-1β (IL-1β) (P < 0.05 or P < 0.01), as well the frequent incidences of inflammatory cell infiltration, hepatic sinus enlargement and fiber stripes formation in histopathological sections. Compared with the model control group, the model low dose group showed significant declines of serum ALT, aspartate transaminase (AST) and total bile acid (TBA) (P < 0.05), as well the alleviation of vacuoles of hepatocytes, but no amelioration of the inflammatory cell infiltration and fibrous tissue hyperplasia; moreover, the model high dose group showed significant degeneration declines of serum HMGB-1, tumor necrosis factor-α (TNF-α) and IL-1β (P < 0.05, P < 0.01), as well the evident alleviation of vacuoles degeneration of hepatocytes, inflammatory cells infiltration and fibrosis degree. The factor analysis showed that the low dosage treatment had almost neither injuring effect on the normal rats nor protective effect on the model rats; while the high dosage treatment showed observable injuring effect on the normal rats, expressed by the significant increases of the factor-1 (HMGB-1, TNF-α and IL-1β as the main contributors) and factor-2 (TBIL, ALT and TBA as the main contributors) relative to the normal control group. The liver protective effect of the high dosage treatment could be observed with the significant reduction of the factor-1, indicating the effective alleviation of the expression of inflammatory cytokines. In conclusion, it could illustrated the phenomenon of symptom-based prescription theory of Polygonum multiflorum on rat livers: the high dosage of the herb had either an injuring effect on normal rats, or a therapeutic effect on the rats with chronic liver injury.

OBJECTIVETo study the toxicity-attenuating effect and the dose-toxicity relationship of rhubarb by processing based on correspondence.

METHODThe effects of different processed materials of rhubarb on the hepatic and renal functions of mice was researched in a way of parallel comparison, as well as the chemical alteration induced by processing was observed. Correspondence analysis, a kind of multivariate statistical analysis, was performed to explore the dose-toxicity relationship of processed materials of rhubarb.

RESULTNo obvious toxic effect was found in mice after single intragastric administration of crude drug of rhubarb at dosage of 76 g x kg(-1), while some lesions to liver and kidney tissues were observed in mice after repeated administration of rhubarb and its processed materials for 14 days at the same dosage. In the correspondence analysis diagram, it could be deduced that there was definite dose-toxicity relationship of processed rhubarb as the distance between trial groups and control group increased along with the dosage and the toxicity. The distance of the processed rhubarb showed as the following consequence: crude drug of rhubarb > vinegar-processed rhubarb > alcohol-processed rhubarb > steamed rhubarb > carbonized rhubarb > Qingning pian. Theerefoer, the toxicity of processed rhubarb was much lower than that of crude drug and the extent of toxicity attenuation was related to the processing intensity. Meanwhile, the toxicity-attenuating effect of processed rhubarb was related to the decline of the contents of both anthraquinone glycosides and tannins, and the former was contributed remarkably to toxicity.

CONCLUSIONThe toxicity-attenuating effect of processed rhubarb was verified in this study and the toxicity of steamed rhubarb attenuated notably while the pharmacological substances degraded little. The correspondence analysis would be useful to assess the pharmacological and toxic effects with multiple indexes of traditional Chinese medicines.
