Objective To study the cryoprecipitate effect of local external treatment of anal fistula surgical wound repair.Methods A total of 95 cases of low simple anal fistula patients was chosen, and was divided into three groups according to random number table method.The cryoprecipitate group (n =32 cases) began with cryoprecipitate dressing (2 layer) even to fill in a wound, once per day.The Kangfuxin group (n =32 cases) used Kangfuxin solution.The exposed burn ointment (MEBO) group (n =31 cases) used MEBO to cover the wound.The healing time, postoperative wound healing rate, the granulation tissue growth, new epithelial coverage, and adverse reactions were observed.Results The cryoprecipitate group in 14 d and 21 d had postoperative wound healing rate (60.97 ±4.20)% and (97.69 ± 1.79)% ,wound healing time (21.31 ±2.08)days;it had higher healing rate and shorter healing times compared to other two groups (P <0.05).Wound repaired more neatly;and 14d and 21d after the operation, wound granulation tissue growth rate [(61.06 ± 13.29) % and (97.63 ± 2.81) %] and new epithelial coverage [(33.03 ±4.15)% and (94.97 ±4.36)%] were more than the control groups (P <0.05) with less adverse reactions relative to control groups.Conclusions The cryoprecipitate contained in the composition has a strong biological activity.It can promote the wound tissue cell growth, and promote the wound repair.

Objective To determinate the heavy metal cadmium content in rice to ensure food safety.Methods Several brands and batch numbers of rice were collected and divided into groups A and B.Group A contained 24 pieces of rice from the canteens,and group B involved in 22 pieces from the farm product markets.Cadmium content in rice was detected quantitatively with X-ray fluorescence spectrometer,and then evaluated according to GB 2762-2012 which determined rice was not qualified in case cadmium content was more than 0.2 mg/kg.Results Group A had cadmium content between 0.00 and 0.477 mg/kg,the times of ultra standard being 2.385 and the disqualification rate being 29.2% (7/24),and group B had cadmium content between 0.065 and 0.619 mg/kg,the times of ultra standard being 3.095 and the disqualification rate being 68.2% (15/22).Excessive cadmium content in rice occurred in both canteens and markets,while the canteens was better than the markets.Conclusion X-ray fluorescence spectrometer detects cadmium content in rice rapidly and simply,and is worthy promoting in elementary facilities.

Objective To discuss the utility of contrast-enhanced ultrasonography (CEUS) in the assessment of treatment efficacy of radiofrequency ablation (RFA) in patients with renal tumors.Methods Forty-seven patients (40 renal cell carcinomas and 7 angiomyolipomas of kidney) with 49 renal tumors were treated with RFA. Tumors were ablated by laparoscopy-assisted (n= 30) and open surgical (n= 17) RFA. The CEUS and contrast-enhanced CT were performed 1 week after treatment to assess the necrotic area. Technical success was defined as elimination of areas that enhanced at imaging within the entire tumor. Results Forty-seven (95. 9%) of 49 tumors were successfully ablated. The mean length of the major axis at the maximal necrotic area was 4. 6 cm. Compared with the lesions before RFA, the necrotic areas were bigger in 45 patients, identical in 3 patients, and smaller in 1 patient. Six lesions showed a residual enhancement at the portion adjacent to the normal renal parenchyma on follow-up CEUS, while 2 were confirmed by CT scans. The sensitivity and specificity of CEUS for detection of residual tumors were 100. 0% and 91.8%, respectively. All patients survived in the follow-up period ranging from 4 to 21 months. Conclusion CEUS combined with CT could be useful for evaluating treatment efficacy of RFA for renal tumors.
