Objective To observe the effect and side effects of concurrent chemoradiotherapy for stage ⅡB~ⅢB cervical cancer. Methods 126 patients with stage ⅡB~ⅢB cervical cancer were randomly allocated into 2 groups. Concurrent chemoradiotherapy group: radiotherapy carried out same as the neoadjuvant chemotherapy group, i.e.firstly with cisplatin 20 mg iv d1-5, 5-Fu 750 mg iv d1-5, repeated every 28 days, total 4 cycle; the neoadjuvant chemotherapy group i.e.firstly with cisplatin 20 mg iv d1-5, 5-Fu 750 mg iv d1-5, repeated every 28 days, total 2 cycle, after chemotherapy received routine radiotherapy 2 Gy per day, 5 times a week to a total dose of 30 Gy with 192Ir brachytherapy, 7 Gy per week. When total dose reached 46 Gy, the middle field was shielded by plumbum, then continuous radiotherapy, total dose reach A point 65-70 Gy, B point 50-56 Gy. Results All patients were followed-up for more than five years. The follow-up rate was 94.4 %. In concurrent chemoradiotherapy group the 3 year survival rate and the 5 year survival rate were 82.8 %, 65.6 %, In neoadjuvant chemotherapy group the 3 year survival rate and the 5 year survival rate were 67.7 %, 46.8 %. There was a significant difference in two groups (X2=3.86, P<0.05; X2=5.01, P<0.05), no significant difference in toxicity-side effect. Conclusion Concurrent chemoradiotherapy for advanced cervical cancer can significantly improve the 3-year and 5-year survival rate and has little increase in toxicity-side effect.

OBJECTIVE:To observe the efficacy and safety of Sanjiao fuzheng mixture combined with concurrent chemoradiotherapy of paclitaxel and nedaplatin in the treatment of local advanced non-small cell lung cancer (NSCLC). METHODS:A total of 68 patients with local advanced NSCLC selected from our hospital during Jan. 2015 to Jan. 2017 were divided into control group and observation group according to random number table,with 34 cases in each group. Control group was given Paclitaxel injection 135 mg/m2 intravenously,d1+Nedaplatin for injection 75 mg/m2 intravenously,d3,21 d as a treatment course,for 2 courses;routine fractionated intensity modulated radiation therapy,2 Gy each time,5 times a week,60-70 Gy in total;given 2 cycles of primary chemotherapy continuously after radiotherapy. Observation group was additionally given Sanjiao fuzheng mixture 250 mL/d,divided into 3 times,till the end of treatment,on the basis of control group. Clinical efficacies were observed in 2 groups. The levels of nutritional indexes (BMI,PAB,ALB,Hb) and tumor markers (SCC-Ag,CEA,TK1, CYFRA21-10) before and after treatment were observed. The occurrence of ADR were recorded. RESULTS:There was no statistical significance in the total effective rate between 2 groups (observation group 82.35% vs. control group 73.53%)(P>0.05). After treatment,the levels of BMI,PAB,ALB and Hb in 2 groups were significantly lower than before treatment,but the observation group was significantly higher than the control group. The levels of SCC-Ag,CEA,TK1 and CYFRA21-1 in 2 groups were significantly lower than before treatment,and the observation group was significantly lower than the control group,with statistical significance (P<0.05). The incidence of Ⅲ-Ⅳ degree aleucocytosis,Ⅰ-Ⅱ degree hemoglobin reduction and thrombocytopenia in observation group were significantly lower than control group, with statistical significance (P<0.05). CONCLUSIONS:The efficacy of Sanjiao fuzheng mixture combined with concurrent chemoradiotherapy of paclitaxel and nedaplatin is similar to that of concurrent chemoradiotherapy of paclitaxel and nedaplatin for localadvanced NSCLC,which can improve nutritional status significantly,and reduce the incidence of ADR.

Objective:
To explore method for isolating and culturing human epidermal stem cells ( EPSCs) in vitro and isolating and purifying epidermal stem cell exsomes ( EPSCs-Exo) by optimizing the technical process.
Method:
Firstly,the improved separating enzyme was used to isolate the EPSCs derived from human skin tissue.Then,an improved serum-free culture medium and 10 specific factors were combined to construct optimized 2D culture medium which could stimulate the growth of EPSCs,promote the secretion of EPSCs-Exo,maintain the stemness and proliferation of EPSCs,and delay the differentiation and maturation of EPSCs. Further,the conditions of differential centrifugation was optimized,and then the human EPSCs-Exo was successfully extracted with high efficiency and high purity.
Results:
The human skin tissue was confirmed with the expressions of markers for epidermal cells. EPSCs were verified with high expression levels of integrin-α6,integrin-β1,P63 and CK19 by immunofluorescence staining and Western blot. The nanoparticle tracking analysis results showed the particles separated for
EPSCs supernatant was saucepan with the detected diameter between 30 - 150 nm. The Western blot results showed the positive expression of membrane markers Tsg101,CD9 and CD63 and the negative expression of intracellular markers Calnexin and GAPDH.
Conclusion
The results show that the human-derived EPSCs have been successfully isolated and cultured in vitro,and the EPSCs-Exo have been successfully isolated and identified.
