Retrospective analysis was performed for the clinical data of 15 chronic insertion achilles tendinitis patients undergoing platelet-rich plasma (PRP) trigger point injection.The scores of Validated Victorian Institute of Sports Assessment-Achilles (VAS-A) and foot function index (FFI) improved greatly versus pre-treatment (all P ＜ 0.05).Tendon insertion structure inflammation decreased significantly on magnetic resonance imaging.At the last follow-up,all patients recovered normal gait and daily activity.The trigger point injection of PRP is efficacious for chronic insertion achilles tendinopathy.

The feasibility of simultaneously loading both liposoluble and water-soluble components of Salvia miltiorrhiza in emulsion was discussed, in order to provide new ideas in comprehensive application of effective components in S. miltiorrhiza in terms of technology of pharmaceutics. With tanshinone II (A) and salvianolic acid B as raw materials, soybean phospholipid and poloxamer 188 as emulsifiers, and glycerin as isoosmotic regulator, the central composite design-response surface method was employed to optimize the prescription. The coarse emulsion was prepared with the high-speed shearing method and then homogenized in the high pressure homogenizer. The biphasic drug-loading intravenous emulsion was prepared to investigate its pharmaceutical properties and stability. The prepared emulsion is orange-yellow, with the average diameter of 241 nm and Zeta potential of -35.3 mV. Specifically, the drug loading capacity of tanshinone II (A) and salvianolic acid B were 0.5 g x L(-1) and 1 g x L(-1), respectively, with a good stability among long-term retention samples. According to the results, the prepared emulsion could load liposoluble tanshinone II (A) and water-soluble salvianolic acid B simultaneously, which lays a pharmaceutical foundation for giving full play to the efficacy of S. miltiorrhiza.

OBJECTIVETo study the effects of Jisuikang (Chinese characters) on Nogo-NgR gene expression, and to explore the protective effects and mechanism of Jisuikang (Chinese characters) on spinal cord injury in rats.

METHODSOne hundred eighty female rats were randomly assigned to 6 groups(30 rats per group). Sham group: T10 lamina was resected only and spinal cord was untreated. Model group: spine cord injury (SCI) was created with a modified impinger of Allen's by impacting on the T10 spinal cord. Prednisolone group: Prednisolone (0.06 g/kg) was given by intragastric administration at a time interval of 24 hours after operation. The Jisuikang (Chinese characters) high, moderate and low dose groups: Jisuikang (Chinese characters) was supplied with different dose (50 g/kg, 25 g/kg, 12.5 g/kg) by intragastric administration in rats after operation,for the first time at 30 min after surgery. Animals were killed 3, 7, 14 days after surgery. The expression levels of Nogo-A and NgR were observed by Western Blot and Real-time PCR.

RESULTSThe expression of Nogo-A and NgR was at the basic level at all time points in sham group. Compared with model group, the protein expression levels of Nogo-A and NgR in sham, prednisolone, Jisuikang (Chinese characters) moderate dose groups were statistically significant at all time points (P < 0.05). No difference was found in Jisuikang (Chinese characters) high and low dose groups (P > 0.05). Three days after surgery, the mRNA levels of Nogo-A and NgR in treatment group were significantly lower than that in model group (P < 0.01); 7 days after surgery,Nogo-A and NgR mRNA expression were dramatically upregulated and peaked; 14 days after operation, the expression was decreased, but still significantly higher than that in other treatment groups (P < 0.01). Prednisolone and Jisuikang (Chinese characters) moderate dose groups showed the most significant effects among all groups,but there was no statistically significant difference between two groups (P > 0.05).

CONCLUSIONThe decoction Jisuikang (Chinese characters) can promote the nerve cell regeneration by regulating Nogo-A and NgR gene expression, activating Nogo- NgR signaling pathways after acute spinal cord injury.

Objective To explore the safety of the mobilization of peripheral blood stem cells(PBSC)by granulocyte colony-stimulating factor(G-CSF)in elderly donors.Methods 28 peripheral arteriosclerotic occlusive disease(PAOD)elderly patients(aged≥60 years),and 29 healthy sibling young/adult donors(aged＜60 years)for peripheral allogenic stem cell transplantation were included.Blood samples were collected immediately before starting G-CSF and prior to PBSC collection to analyze the following parameters:the WBC counts,fibrinogen(FIB),D-dimer (D-D),thrombin antithrombin complex(TAT),antithrombin(AT)and yon Willebrand factor antigen(vWF:Ag). Results It had a very significant increase in D-D and vWF:Ag and a very significant decrease of AT(P＜0.01),af- ter mobilization by G-CSF,and a increase in FIB and TAT were also observed(P＜0.05,P＜0.01)in elderly group.In the young/aduh group,the increase in FIB was significant(P＜0.05).The elevating extent of D-D and TAT after G-CSF administration was significantly higher in elderly group than that in young/adult group(P＜0.05).Compared to young/adult group,there was a significant increase in thrombotic events and cerebrovascular ac- cident(P＜0.05).Conclusion In PBCS donorsreceiving G-CSF it reveals activation of both coagulation and en- dothelial cells and inhibition of anticoagulant system that can favor the developing of thrombotic events,which is more remarkable in elderly donors.Therefore a careful monitoring for coagulation system should be considered in those elderly cases.

Chronic obstructive pulmonary disease (COPD), a common preventable and treatable disease, is characterized by airflow limitation that is usually progressive and associated with an enhanced chronic inflammatory response in the airways. Its main pathological manifestations include airway inflammation, mucus hypersecretion, oxidative stress and apoptotic epithelial cells. Recent research suggests that MAP kinases and Keap1-Nrf2-ARE signaling pathway are involved in the pathological process of inflammation and oxidative stress. This review explores the potential role of the cross talk of these signaling pathways in airway inflammation, mucus hypersecretion, oxidative stress and apoptotic epithelial cells. To clarify the roles of cross talk between MAP kinases and Keap1-Nrf2-ARE signaling pathway, we also focus on the drugs related to that in the treatment of COPD, and it provides ideas for more drug research in the treatment of COPD.

Microdialysis technique in free-moving animals can be used to monitor continuously the changes of many extracellular neurotransmitters in certain brain areas and study the relationship between neurotransmitter and functions. Using detection of capillary electrophoresis combined with laser-induced fluorescence (CE-LIF) further improves the above-mentioned technique. In the present study, fluorescein isothiocyanate (FITC) was used to derivatizate amino acid in very low concentration. We found that increasing derivatization temperature could shorten derivatization time and that the derivatizative efficiency was not different from that when experiment was performed under the traditional derivatization condition (room temperature for 16 h). We also got an optimized condition of amino acid derivatization with FITC at 30 degrees C water bath for 5 h. Using the optimized condition of amino acid derivatization, we investigated the changes in L-arginine (L-Arg) and L-glutamate (L-Glu) concentration in periaqueductal gray matter (PAG) microdialytes of free-moving morphine-withdrawal rats. The results indicated that there was no significant difference in the concentration of L-Arg and L-Glu in PAG between non-dependent and dependent rats. The concentration of L-Arg and L-Glu in PAG increased by 63% and 105%, respectively, in the first 10 min after naloxone-precipitated withdrawal and then declined gradually. These changes were in correspondence with the scores of morphine withdrawal symptom.

OBJECTIVETo explore the relative factors on the failure in digit replantation in order to take preventions to control the risk factors.

METHODSFrom January 2013 to December 2013, 236 consecutive patients (311 fingers) underwent digit replantation were collected to analyze retrospectively, involving 183 males and 53 females with an average age of 34.5 years old ranging from 2 to 62 years old (6 cases under 6 years old and 230 cases elder than 6 years old). There were 51 thumbs, 87 index fingers, 78 middle fingers, 63 ring fings and 32 little thumbs. Forty cases(forty fings) who were failured as the observation group, the others as the control group. The factors of age, gender, finger, cause of injury, smoking history, ischemia duration, plane of division, condition of venous drainage and condition of arterial repair we assessed.

RESULTSAll 236 cases with 311 fingers were replanted, 40 fingers were failured after operation. The relative factors on the failure in digit replantation included smoking history, cause of injury, plane of division, condition of venous drainage and condition of arterial repair (P< 0.05). There were no significant correlation between the failure and age, gender, finger and ischemia duration (P>0.05).

CONCLUSIONSmoking history, causes of injury, plane of division, condition of venous drainage and condition of arterial repair are risks of failure in digit replantation. Before choosing the type of operation, it should be think about the patient's general conditions, injury status, grasp firmly the operative indications and actively carry out surgical treatment.

OBJECTIVETo study the antiproliferation effect on HepG2 cells and its underlying mechanism of the active chemical composition of the Viburnum Odoratissimum.

METHODS3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) reduction assay and trypan blue dye exclusion assay were used to assess the effect of vibsane-type diterpenoids on the proliferation of various tumor cells. Alterations in cell cycle and apoptosis were determined by flowcytometry. The enzymatic activity of caspase-3/7 was measured by Apo-ONE homogeneous Caspase-3/7 Assay kit.

RESULTSCompound 1 #, a vibsane-type diterpenoid, was found to significantly inhibit the growth of HepG2 cells by anticancer proliferation activity screening. It was demonstrated that the modified groups on side chain coupled to C11 site affected the cell growth-inhibition activity of compounds by structure-activity analysis. In addition, HepG2 cell line was most sensitive to compound 1 #, which induced growth arrest of HepG2 cells in a dose- and time-dependent manner. Study on the mechanisms underlying these effects indicated that compound 1 # induced significant G0/G1 phase arrest of HepG2 cells in a time- and concentration-dependent manner. Meanwhile, It was found that higher concentrations of compound (5-10 micromol/L) caused evident increase in the unmber of apoptotic cells and dose-dependent activation of caspase-3/7.

CONCLUSIONVibsane-type diterpenoids could significantly inhibit the growth of HCC HepG2 cells. Induction of cell cycle arrest and apoptosis may play important roles in their anticancer effects.
