OBJECTIVE: To observe the effect of triamcinolone combined with vitamin E on preventing fibrous capsule contracture following the second breast augmentation. METHODS: Totally 65 patients who had 130 breasts receiving the second breast augmentation at the Department of Plastic and Aesthetic Surgery, No.1 People's Hospital of Nanning were collected and served as the treatment group, including 47 cases with capsules contracture and 18 cases with hydrogel clearing. Tri-Kort was injected after the second breasts augmentation, and vitamin E was taken orally for 3 months. Additional 65 cases with 130 breasts received the second breast augmentation were served as control group. The follow-up was performed after half month, and the curative effect was evaluated by Baker grading at 1 year after operation. RESULTS: All cases in the two groups were received 6-24 months follow-up. Only 3 cases (5 breasts) in 65 patients (130 breasts) in the treatment group had capsule contracture (Baker II-III), with 3.8% of capsule contracture, which was obviously less than 18% of capsule contracture in the control group (P < 0.01,13 cases with 23 breasts in the control group). Simultaneously, no drug adverse reaction occurred in the treatment group. CONCLUSION: Triamcinolone combined with vitamin E can obviously depress the rate of capsule contracture after the second breast implantation.

Objective To compare the efficacy and side effects of S-1 combined with oxaliplatin and capecitabine combined with oxaliplatin in treatment of advanced gastric cancer. Methods From Mar 2011 to Dec 2014, the data of 93 cases with gastric cancer in Zhengzhou Peopleˊs Hospital were studied retrospectively. 48 cases treated by S-1 combined with oxaliplatin (SL group) and 45 cases treated by capecitabine combined with oxaliplatin (XL group). The patients of SL group received S-1 80 mg·m-2·d-1, bid, po, d1-14, L-OHP 130 mg/m2, ivgtt, 2 hours, d1. The patients of XL group received capecitabine 2 000 mg·m-2·d-1, bid, po, d1-14, L-OHP 130 mg/m2, ivgtt, 2 hours, d1. The course was 21 days in two groups. The efficacy and side effects were evaluated after two courses. Results The efficacy rates of SL and XL group were 52.08 % (25/48) and 53.33 % (24/45), respectively there was no significant difference (P > 0.05). The incidence rate of gastrointestinal reaction in SL group was obviously higher than that in XL group [52.08%(25/48) vs 24.44%(11/45), P<0.05]. The incidence rate of oral mucositis in SL group was significantly lower than that in XL group [25.00 % (12/48) vs 51.11 % (23/45), P< 0.05]. Conclusion Both S-1 combined with L-OHP and capecitabine combined with L-OHP for gastric cancer treatment are safe and effective.

Objective To investigate the protective effects of (Val8)GLP-1-Glu-PAL to dopaminergic neurons on PD mice induced by MPTP.Methods 56 male C57BL/6 mice which are 10-12 weeks old were randomly divided into Control,model (MPTP),muti-injection (Val8) and therapy (MPTP + Val8) groups by random number table method.Mice in MPTP group were received MPTP IP.treatment (30mg/kg · d),the control group were treated with 0.9％ saline with the same volume,Val8 group were injected with (Val8) GLP-1-Glu-PAL (25 nmol/kg),and MPTP+Val8 group were going to received (Val8)GLP-1-Glu-PAL 1 h after treatment of MPTP,all the groups were treated for 8 consecutive days.Behavior test were processed 2h after drug IP injection,including swimming test and rotarod test.Mice were sacrificed immediately 1h after the final trail of behavior test in 8th day,brains were withdraw for IHC assay which tested the number TH positive neurons in SNpc area.Results The classical PD behavior symptom were induced by MPTP,from 1 st to 8th,the swimming score(1.715±0.143 and dropping latency(68.048±7.823) were both decreasing compared with control.The differences were statistically significant (P＜0.05).The positive dopaminergic neurons were significantly lower in SNpc area (P＜0.01).Compared with MPTP group,(Val8) GLP-1-Glu-PAL could statistically improved the behavior deficit,the swimming score (1.120±0.143) and dropping latency(20.546±7.823) in the MPTP+Val8 group,and differences were statistically significant (P＜0.05).Meanwhile,the TH positive neurons were significantly elevated (P＜0.01).Conclusion The results suggest that (Val8)GLP-1-Glu-PAL has protective effects for MPTP induced mice PD dopaminergic neurons.

Objective To explore the characteristics of constitution according to traditional Chinese medicine and the anxiety susceptibility of the population, providing the theoretical basis for carrying out population intervention in anxiety and taking full advantage of the preventive treatment by investigating anxiety emotion of patients. Methods A cross-sectional study method was adopted. 317 anxiety patients were recruited into an observation group and another 251 anxiety patients were recruited into a control group. Based on the traditional Chinese medicine constitution scale we defined every participant’s constitution type and got the distribution of different constitution types among all the participants. Then we usedχ2 test and binary regression to analyze the impact of constitution on anxiety. Result The observation group constitution type distribution:Qi stagnation(19.24%), Qi deficiency(16.40%), blood stasis(15.46%), damp heat (11.04%), Yang deficiency(10.41%), Yin deficiency(8.83%), phlegm dampness(6.62%), mild quality(5.99%), special intrinsic quality(5.99%). The control group constitution type distribution:damp heat(17.53%), Yin deficiency (14.34%), phlegm dampness (13.94%), Yang deficiency(11.55%),mild quality (11.55%), Qi stagnation (8.76%), Qi deficiency (8.37%), blood stasis (7.97%), special intrinsic quality (5.98%). The result ofχ2 test showed that the distribution of constitution types among participants in the observation group were different from that in the control group and the difference was statistically significant(P<0.001). Three kinds of constitution types(Qi stagnation, Qi deficiency, Blood stasis)showed a different distribution percentage in the observation group(51.10%)and the control group(25.10%, P<0.01). In the observation group, the distribution ratio among Qi stagnation, Qi deficiency, blood stasis had no significant differences (P>0.05). The binary regression result showed that the three constitutions of Qi stagnation, Qi deficiency and blood stasis had significantly positive correlation with anxiety(P<0.05). Odds ratios showed Exp of Qi stagnation, Qi deficiency and blood stasis was 4.447, 3.942 and 3.929. while the other six constitutions are independent factors to anxiety. Conclusion Qi stagnation, Qi deficiency and blood stasis constitutions were possible risk factors for anxiety.

Patrolling monocyte (PMo) is a subset of monocytes.Its main function is patrolling vascular endothelium and removing cellular debris from the microvasculature.Studies have revealed that PMo can inhibit the growth of tumor cells,recruiting NK cells to kill tumor cells.PMo can prevent tumor cells metastasis to the lung,which plays a role of immunosurveillance.PMo may be a target for cancer immunotherapy.

Objective To investigate the relationships between the parameters of intravoxel incoherent motion (IVIM)DWI at 3.0 Tesla and T staging of moderately differentiated adenocarcinoma of rectum.Methods Clinical data and MRI findings including con-ventional imaging and IVIM-DWI were collected in a total of 37 patients with moderately differentiated adenocarcinoma of rectum proven by pathology.The patients were divided into two groups without (staging T1 and T2)or with myometrial invasion (T3 and T4).The D,D? ,f and ADC values of rectal cancer and normal rectal wall were measured and were compared between the lesion and normal rectal wall,between both groups and among different T stages.The relationships of the parameters of IVIM-DWI and ADC values with the T staging of moderately differentiated adenocarcinoma of rectum were analyzed.Results The D,D? ,f and ADC val-ues of rectal cancer were lower than those of normal rectal wall with statistical differences in D,f and ADC values (P <0.05).The differences in D and D? values among different T stages were statistically significant,and LSD Duncan test showed that the differ-ence in D? value between T1 and T4 (P =0.01 7)and between T3 and T4 (P =0.003)and in D value between T2 and T3 (P =0.005) were statistically significant.The D,f,D? and ADC values of noninvasion group and invasion one were (0.93±0.1 6)×10 -3 mm2/s versus (0.77±0.1 9)×10 -3 mm2/s,(27.1±2.94)% versus (24.6 ±4.13)%,(12.6±2.44)×10 -3 mm2/s versus (12.3±3.49)× 10 -3 mm2/s,and (0.95±0.09)×10 -3 mm2/s versus (0.87 ±0.12)×10 -3 mm2/s respectively,and the difference in D value was statistically significant (t=2.5 12,P =0.01 7).Conclusion The parameters of IVIM-DWI and the ADC values are different in rectal cancer and normal rectal wall,and the D value may help to identify the tumor invasion into the muscularis propria.

Aim To observe the correlation between the TPL's suppression on myofibrolbasts(MFBs)activation and TGF-β1/ERK/Smad3 pathway by performing in vivo and in vitro experiments.Methods In vitro model of MFBs activation was set up by stimulating fibroblasts with TGF-β1,and in vivo model of MFBs activation in radiated lung tissue was built by thoracic radiation on C57BL/6 mice.MFBs activation was analyzed by detecting the expression of α-SMA(using RT-PCR and Western blot)and Col Ⅰ(using RT-PCR and ELISA methods).The levels of p-ERK,p-Smad3(Ser208)and p-Smad3(Ser423)were measured by Western blot.ERK siRNA and Smad3 siRNA were used to observe the status of ERK and Smad3 in MFBs activation.Results TGF-β1 activated p-ERK/p-Smad3(Ser208)and p-Smad3(Ser423),increased the expression of α-SMA and synthesis of Col Ⅰ,which indicated MFBs activation.siRNA knockdown assay showed that both ERK and Smad3 were involved in regulating the levels of α-SMA and Col Ⅰ,and ERK influenced MFBs transformation possibly through its phosphorylation of Smad3(Ser208).TPL treatment inhibited the phosphorylation activation of ERK,Smad3(Ser208),Smad3(Ser423)in vitro and in vivo,therefore significantly reduced the level of α-SMA and Col Ⅰ,and the number of activated MFBs was decreased.Conclusion TPL mitigates radiation-induced pulmonary fibrosis by inhibiting the activation of MFBs,which is partly through suppressing TGF-β1/ERK/Smad3 pathway.
