Objective To study the effect of arthroscopy in conjunction with minimally invasive percutaneous plate osteosynthesis (MIPPO) in the treatment of tibial plateau fracture.Methods 78 cases of tibial plateau fracture patients admitted during March 2011 and June 2014 were retrospectively analyzed, with 38 cases given the conven-tional open reduction treatment (group A) and 40 given arthroscopy in conjunction with MIPPO (group B).The clini-cal efficacy, Rasmussen excellent rate and good rate, and postoperative complications in both groups were then com-pared.Results The operative time showed no significant difference in both groups (p >0.05); the time of hospital-ization, the length of surgical incision and healing time of group B were significantly better than group A (p <0.05);after follow -up observation, Rasmussen excellent rate and good rate of group B were significantly higher than group A (p <0.05).Conclusion Arthroscopic in conjunction with MIPPO has the advantages of smaller surgical wound, faster recovery and fewer complications, and have good efficacy and better clinical value for the treatment of tibial plateau fractures.

Objective To investigate the effect of adenoviral-mediated interleukin-10 (IL-10) gene transfection on systemic inflammatory responses in a rat model of ventilator-induced lung injury. Methods Thirty adult male SD rats weighing 200-220 g were randomly divided into 5 groups (n=6 each): group Ⅰ control (group C); group Ⅱ adenovirus without IL-IO gene + 2 h mechanical ventilation (MV) (group B, ); group II1 adenoviruswithout IL-IO gene + 4 h MV (group B_2); group Ⅳ adenovirus with IL-10 gene + 2 h MV (group A_1) and group Ⅴ adenovirus with IL-10 gene + 4 h MV (group A_2). In group Ⅱ-Ⅴ the animals were mechanically ventilated (airway pressure = 25 cm H_2 O) and adenovirus was injected into right ventricle at 48 h before MV. Blood samples were taken from abdominal aorta at the end of 2 h or 4 h MV for determination of serum IL-8 and IL-10 concentrations. The animals were then killed. The pulmonary specimens were obtained for examination of ultrastructure with light and electron microscope. Results Mechanical ventilation significantly increased serum IL-8 and IL-IO concentrations in a duration-dependent manner in group Ⅱ-Ⅴ as compared with group C. Trans-pulmonary administration of adenoviraI-mediated interleukin-10 gene significantly decreased serum IL-8 concentration and increased serum IL-10 concentration and reduced ventilator-induced lung injury alter MV in group A_1 and A_2 as compared with group B_1 and B_2. Conclusion Adenoviml-madiated IL-10 gene transfection can attenuate the systemic inflammatory response and reduce ventilator-induced lung injury.

Objective To evaluate application of quality care in prevention of general surgery wound infection in elderly patients. Methods 116 cases of elderly patients undertook general surgery from October 2013 to October 2014 were selected in alphabetical order by pinyin of last name as the research objects, who were divided into the observation group (58 cases) and control group (58 cases) by lottery. The control group received routine care, the observation group received quality care. The occurrence of wound infection and the hospitalization time were compared. Results The incidence of wound infection of the observation group was 6.9%(4/58), which was lower than that of the control group [24.1%(14/58),χ2=6.576, P<0.05]. The hospitalization time of the observation group was lower than that of control group [(22.6±3.2) d vs.(28.6±3.8) d, t=5.401, P<0.05]. Conclusions Quality care contributes to reduce the incidence of wound infection on general surgery incisions of elderly patients, and promotes the recovery of patients.

Erhuang quzhi compounds is one of the protecting liver and inhibiting toxin prescriptions series summarized by Jinqi Yuan and other famous doctors of traditional Chinese medicine during the long-term clinical practice. It is very effective for non-alcoholic fatty liver disease (NAFLD), but its mechanism is not clear. This research investigated mechanism of Erhuang quzhi granules (EQG) in the treatment of NAFLD. All the animal welfare and experimental procedures are in accordance with the regulations of the Animal Ethics Committee of the First Affiliated Hospital of Shihezi University. Mouse models of NAFLD were established by feeding with methionine and choline deficient diet (MCDD) for five weeks. While feeding MCDD, the treatment groups were given EQG (16.25 g·kg^-1·d^-1) and atorvastatin (ATO, 7.20 mg·kg^-1·d^-1) by gavage. The effects of EQG on serum biochemical indices, liver pathological changes, and inflammatory cytokines in mice of NAFLD were investigated. Quantitative real-time PCR (qPCR), immunocytochemistry (ICH) and Western blot assays were used to detect the levels of mRNA and protein associated with nuclear factor kappa B/Nod-like receptor protein 3 (NF-κB/NLRP3) in liver. The results showed that EQG significantly reduced the levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT), and improved the level of low-density lipoprotein cholesterol (LDL-C). The result of hematoxylin-eosin (HE) staining showed that EQG reduced lipid deposition in livers of mice. Meanwhile, EQG notably decreased the levels of interleukin (IL)-1β, IL-6, IL-18 and tumor necrosis factor-α (TNF-α), and mRNA levels of NF-κB, NLRP3, IL-1β, TNF-α, down-regulated the expression of F4/80, IκB kinase β (IKKβ), NLRP3 and apoptosis-associated speck-like protein containing a CARD (ASC) and inhibited the activation of NF-κB and cysteinyl aspartate specific proteinase-1 (caspase-1). These findings announced that EQG could improve NAFLD via NF-κB/NLRP3 pathway possibly, which provides a theoretical basis for the further development and utilization of EQG in clinic.

Objective: To optimize the formulation of Panax notoginseng saponins (PNS) transfersomes and to verify their effects on acute soft tissue injury in rats. Methods: Thin film dispersion method was employed to prepare PNS transfersomes. Based on the elasticity of transfersomes, PNS transfersomal formulation was optimized by a uniform experimental design. Extrusion method and centrifugation-ultrafiltration method were respectively adopted to determine the elasticity and the entrapment efficiency (EE) of PNS transfersomes. The therapeutic effects of PNS transfersomes on acute soft tissue injury in rats were evaluated by observing the indexes of injury symptom, the hemorheology and the histomorphology with Qingpeng Ointment being used as positive control. Results: The optimum formulation was as follows: PNS 100 mg, cholesterol 15 mg, soybean phospholipid 120 mg, vitamin E 2 mg, volatile oils (limonene-citral = 4:1) 80 mg, and hydration liquid (phosphate buffered saline, pH 5.0) 10 mL. The optimized PNS transfersomes had elasticity of (2.74 ± 0.32) min, average size of (123.6 ± 0.36) nm, Zeta potential of (-36.67 ± 2.29) mV, and EE of (82.42 ± 0.69)% and (94.40 ± 0.74)% for ginsenoside Rg1 and ginsenoside Rb1, respectively. The results of pharmacodynamical tests showed that the PNS transfersomes could significantly improve the injury symptom indexes (P < 0.01) and hemorheology (P < 0.05) of the rats compared with model control, and it could also improve their histomorphology. Conclusion: The optimized PNS transfersomes with an appropriate size, desired elasticity, and drug EE are effective for the acute soft tissue injury in rats.

Base on the Kawakita powder compression equation, a general theoretical model for predicting the compression characteristics of multi-components pharmaceutical powders with different mass ratios was developed. The uniaxial flat-face compression tests of powder lactose, starch and microcrystalline cellulose were carried out, separately. Therefore, the Kawakita equation parameters of the powder materials were obtained. The uniaxial flat-face compression tests of the powder mixtures of lactose, starch, microcrystalline cellulose and sodium stearyl fumarate with five mass ratios were conducted, through which, the correlation between mixture density and loading pressure and the Kawakita equation curves were obtained. Finally, the theoretical prediction values were compared with experimental results. The analysis showed that the errors in predicting mixture densities were less than 5.0% and the errors of Kawakita vertical coordinate were within 4.6%, which indicated that the theoretical model could be used to predict the direct compaction characteristics of multi-component pharmaceutical powders.
