Objective To study the effect of dimethylaminoethano (DMAE) and compound amino acid injection (AA) by mesotherapy on collagen Ⅰ and collagen Ⅲ mRNA expression levels of D-galactose-induced chemical skin aging rats.Methods 80 rats were randomly divided into individual experimental group.At 18 days after D-gal induction,rats of aging treatment groups were treated with intradermal microinjection of 0.2％ DMAE+AA,0.1％ DMAE+AA,0.2％ DMAE,0.1％ DMAE,AA,and saline,respectively,once a week for 4 weeks.At 42 days after treatment,the skin wounds were harvested.HE,PCNA,hydroxyproline and collagen Ⅰ and collagen Ⅲ mRNA expression levels of every group skins were detected.Results Dermal thickness,hydroxyproline content and collagen type Ⅰ and Ⅲ mRNA expression levels of 0.1％ DMAE+ AA and 0.2 ％ DMAE+ AA groups were significantly improved (P＜0.05),but PCNA expression of sham control group was significantly higher than all of aging groups (P＞0.05).Conclusions Local co-injection of DMAE and compound AA directly into targeted tissue under mesotherapy has marked anti-aging effects on D-galactose induced skin aging model of rat by increasing the dermal thickness,collagen content and acceleration of collagen synthesis.

Objective To explore the levels and clinical significance of anti-beta 2-glycoprotein 1 antibodies (β_2GP1), matrix metalloproteinase 9 (M M P-9) in the plasma of children with Kawasaki diseases (KD). Methods Serum level of anti-β_2GP1 antibody and MMP-9 was measured in 47 children with KD by ELISA, and the data was analyzed using SPSS11.5 software. Thirty age matched children with infectious diseases(sepsis or pneumonia), exclusive of heart, liver, kidney, blood diseases and autoimmune diseases such as rheumatoid were chosen in the fever control group. Results Coronary artery lesions (CAL)were found in 17 children of KD group (17/47) by Doppler ultrasound examination. Significant differences (P < 0.05) of serum level of anti-β_2GP1 antibody was showed between KD group ((7.46 ± 2.13) U/ml)and the control group ((4.38 ± 0.43) U/ml) ; serum level of MMP-9 was (886.62 ± 92.72) ng/ml and (460.06 ± 179.59) ng/ml in KD group and the control group respectively, with significant difference between the two groups(P < 0.05). In KD group, levels of anti-β_2GP1 were (8.83 ± 0.89) U/ml among children with CAL and (6.18 ± 1.42) U/ml among children without CAL, serum level of MMP-9 was (948.62 ± 81.76) ng/ml and (872.00 ± 34.74) ug/ml respectively, with significant differences(beth P < 0.05). In children with KD, the serum levels of anti-β2GP1 antibody and MMP-9 were significantly correlated (correlation coefficient r = 0.665). Conclusions Serum levels of anti-β_2GP1 antibodies and MMP-9 increased in the acute phase of KD, and were significantly higher in those KD children with CAL.Anti-β_2GP1 antibodies and MMP-9 may play a role in the pathogenesis of KD, and can be used as an important serological indicator of KD with CAL.

Conclusion The upper described four modes of blockade are similar in decreasing the pressure of the internal iliac artery net.Thereby,only one of them is enough in management of artery hemorrhage following pelvic fractures.

Aim To investigate the effects of Aplysin on the inhibition of gastric cancer cell in vitro .Methods MTT assay was used to examine the inhibition of gastric cancer cell 1ine SGC-7901 by Aplysin in different concentrations and at different times.The morphologic changes and the apoptosis of SGC-7901 was observed by inverted microscope and Hematoxylin-Eosin(HE)staining.Reverse transcriptase polymerase chain reaction(RT-PCR)assay was used to detect the changes of COX-2 mRNA expressions.Results Aplysin could decrease the proliferation significantly in a dose-dependent manner in SGC-7901 cells.When treating SGC-7901 with Aplysin in concentration of 120, 240 mg·L~(-1) for 24 h, the growth of the cell was obviously inhibited observing by inverted microscope.Aiso, when treating with the same concentration for 18 h, its chromatin became crimpled and breakdown, as well as cell shrinkage and apoptotic bodies formation when using HE staining.The apoptotic rates(%)of SGC-7901 was(15.0±2.12)%, (18.4±2.3)%, respectively, which was significantly higher than(1.4±0.55)% that in control group(P <0.01).60、120、240 mg·L~(-1) Aplysin could not effectively inhibited the mRNA expressions of COX-2(P ＞0.05).Conclusions Aplysin can inhibit the proliferation and induces apoptosis of SGC-7901 cells.

The first metatarsophalangeal joint bending plays an important role in the foot movement. However, the existing researches mainly focused on the movement scope of the joint and the clinical treatments of related foot diseases. In order to investigate the effects of the first metatarsophalangeal joint bending on human walking gait stability, the present researchers recruited 6 healthy young men to perform the first metatarsophalangeal joint constraint (FMJC) and barefoot (BF) walking tests. Data of the temporal and spatial parameters, the joint angles of lower limbs, the ground reaction forces (GRF) and utilized coefficients of friction (UCOF) were collected and analyzed. The results showed that, since hip and knee could produce compensation motions, the FMJC had no significant effects on waking gait, but the slip and fall probability increased significantly.

OBJECTIVE:To observe therapeutic efficacy and safety of S-1 capsules combined with recombinant human end-ostatin in the treatment of middle and advanced primary liver carcinoma. METHODS:Totally 94 patients with middle and advanced primary liver carcinoma in the First College of Clinical Medical Science of China Three Gorges university during Feb. 2012-Dec. 2014 were divided into combination group(48 cases)and control group(46 cases)according to random number table. Both groups were given S-1 capsules 40-60 mg orally within 30 min after breakfast and supper. Combination group additionally received Recom-binant human endostatin injection 150 mg added into 0.9%Sodium chloride injection 210 mL with portable micro pump for continu-ous pump of 120 h. A course involved 14 d treatment and 7 d interval. Short-term objective therapeutic efficacy,clinical benefit re-sponse (CBR) and ADR were evaluated after 2 courses. Disease progression time and average survival period were compared be-tween 2 groups. RESULTS:Objective response rate,disease control rate,disease progression time and average survival period of combination group were 14.6%,66.7%,(5.5 ± 1.3) months,(10.7 ± 3.8) months;those of control group were 8.7%,45.6%, (4.8±1.2)months,(8.9±3.3)months,with statistical significance between 2 groups(P<0.05). CBR rate of combination group (79.2%)was significantly higher than control group(52.2%),with statistical significance(P<0.05). There was no statistical sig-nificance in the incidence of ADR between 2 groups (P>0.05). CONCLUSIONS:S-1 combined with recombinant human end-ostatin show good therapeutic efficacy and tolerance for patients with middle and advanced primary liver carcinoma,and do not in-crease the incidence of ADR.

Aim To investigate the protective effects of Aplysin on ethanol-induced oxidative damage in rat pri-mary hepatocytes. Methods Rat primary hepatocytes were obtained via the portal vein collagenaseⅣin situ perfusion technique followed by a Percoll density gradi-ent centrifuge. MTT test was used to determine the op-timum dose of Aplysin and ethanol, and detect the cell vitality in primary hepatocytes. Supernatants of primary hepatocytes were harvested to measure AST and LDH level, and the SOD, GSH-PX activities and MDA con-tent in primary hepatocytes were observed. Flow cy-tometry was used to detect the cell apoptosis rate. DNA damage in primary hepatocytes was detected by single-cell gel electrophoresis assay. The level of mitochon-drial membrane potential in primary hepatocytes was tested by fluorogenic probe JC-1 . The CYP2 E1 activity in primary hepatocytes was detected by colorimetry. The proteins of CYP2 E1 were detected by Western blot. Results 300 mmol·L-1 dose of ethanol and 30 mg·L-1 dose of Aplysin were the optimal dosages and were used in the subsequent experiments. Hepatocyte vitality was significantly increased in Aplysin group compared to that in ethanol group, and Aplysin inhibi-ted the release of AST and LDH(P<0. 05). For Apl-ysin treatment group, the activities of hepatocyte SOD and GSH were significantly increased, and MDA was markedly lowered as compared with those in ethanol group( P <0. 05 ) . Aplysin could alleviate hepatocyte apoptosis significantly, and hepatocyte DNA damage rates of Ⅱ ~Ⅲ level and Ⅳ level were significantly lowered in Aplysin treatment group as compared with those in ethanol group, and Aplysin had evident im-provement in alcohol induced mitochondria damage of hepatocyte. Primary hepatocyte activities and protein expression of CYP2 E1 were markedly lowered in Aply-sin treatment group as compared with those in ethanol group(P<0. 05). Conclusion Aplysin has protective effects on liver oxidative damage induced by alcohol of primary cultured rat hepatocytes by blocking CYP2 E1 activation, relieving oxidative stress, and sharpening the oxidation resistance ability.
