Objective To study the expressions and significances of matrix metalloproteinases-3 (MMP-3) and tissue-inhibitor of matrix metalloproteinase-3 (TIMP-3) in transitional cell carcinoma of bladder.Methods Immunohistochemistry was used to detect the expressions of MMP-3 and TIMP-3 in 48 cases of transitional cell carcinoma of bladder and 20 normal bladder tissues.Results MMP-3 and TIMP-3 in normal bladder tissues did not express.The more grading and staging,the more MMP-3 expression,but no statistical significance(P ＞0.05),by contrast,TIMP-3 expression decreased and has statistically significant in the tumor grading (P ＜ 0.05).Conclusions High expression of MMP-3 and low expression of TIMP-3 is related to the malignancy of transitional cell carcinoma of bladder and may play an important role in the development of transitional cell carcinoma of bladder,as an important reference to judge the degree of malignancy of transitional cell carcinoma of bladder and prognostic indicator.

Objective To evaluate the value of interstitial magnetic resonance lymphography (MRL) to identify the sentinel lymph node (SLN) of breast cancer.Methods Totally 58 patients with invasive breast cancer were consecutive collected.15 mL of Gd-DTPA and 2 mL of mepivacain hydrochloride 2% were mixed and 0.5 mL of them was injected into the outside of the subareolar breast tissue.MRI was performed with Siemens 3.0 T Magnetom Trio MRI instrument using volumetric interpolated breath-hold examination sequence.Axillary lymph flow was tracked on maximum intensity projection (MIP) and sentinel lymph nodes were identified by interstitial MRL as M-SLN.All M-SLN were marked by a method of surface capsule localization.During surgery, methylene blue was used as tracer and SLNs stained by it were detected and excised by following the blue lymphatic vessels,these were designated as D-SLN.The numbers of SLNs detected by interstitial MRL and stained by methylene blue during operation were compared by paired samples rank-sum test and the correlation was analyzed by Spearman rank correlation test.Assessing the sensitivity, specificity and accuracy of interstitial MRL for diagnosing M-SLN.Results A total of 75 M-SLNs (average 1.60 ± 0.52) were identified by interstitial MRL.During operation, all M-SLNs were easily resected under the guidance of skin marker.91 D-SLNs (average 1.94±0.63) were stained by methylene blue, which was significant more than those of the M-SLNs.There was a strong correlation (Spearman's rank correlation coefficient 0.69,P<0.001) between the SLNs identified by these two methods.Interstitial MRL in diagnosing D-SLN metastasis of breast cancer had a sensitivity of 95.8%,specificity of 88.9%,and accuracy of 93.3%.Conclusion Interstitial MRL can accurately identify the axillary sentinel lymph node and guide the biopsy.It may have great clinical value in the future.

Objective To reduce the incidence of peritoneal dialysis related peritonitis for patients in rural area and to improve management quality of peritoneal dialysis center.Methods We established multidisciplinary collaborative research group involving departments of nephrology,nutrition,infection,and quality control.Risk factors of peritoneal dialysis related peritonitis in rural patients were analyzed,and prevention measures were designed.The rate of peritoneal dialysis related peritonitis in 89 patients after implementation was analyzed.Results The rate of peritoneal dialysis related peritonitis was decreased from 43 patient·month per time to 67 patient ·month per time.Conclusion The compound pathway can effectively reduce the rate of peritonitis,improve patient satisfaction,and prolong dialysis age.

【Objective】 To investigate the feasibility of allogeneic platelet-rich plasma (PRP) for the treatment of skin injury around enterostomy. 【Methods】 The treatment process by PRP of 2 patients with skin injury around enterostomy was analyzed, and the PRP for each patient was tested with platelet count, bacteria and 5 growth factors. The clinical efficacy of enteral nutrition support therapy combined with allogeneic PRP was explored through analyzing treatment key points and literature review. 【Results】 After cleaning the skin around enterostomy, the patients were treated with PRP once daily for 5 days, adjusted to once every other day, and cure was achieved at 15 and 18 days, respectively. 【Conclusion】 Allogeneic PRP is a safe and effective treatment to promote skin injury around enterostomy regeneration in a short time, which can provide a new perspective for clinical.

OBJECTIVEOn the basic therapy, to assess the clinical effects of dynamic scalp acupuncture, scalp acupuncture combined with proprioceptive neuromuscular facilitation (PNF) therapy and simple PNF therapy for upper limb motor impairment in ischemic post-stroke spastic hemiplegia.

METHODSA total of 90 cases were randomly assigned into a PNF group, a dynamic scalp acupuncture group and a scalp acupuncture group, 30 cases in each group. Basic therapy and PNF therapy were applied in the three groups. PNF therapy was used during scalp acupuncture in the dynamic scalp acupuncture group. PNF therapy was applied after scalp acupuncture in the scalp acupuncture group. The points were the upper 1/5 and middle 2/5 of (MS 6) and (MS 7) at the lesion side, the hemiparalysis contralateral side. The treatment was given for 6 months, once a day and 1 month as a course. The modified Ashworth scale (MAS), the Fugl-Meyer motor assessment (FMA) and Barthel index (BI) were observed before treatment and 2 weeks, 1 month, 3 months, and 6 months after treatment.

RESULTSThe MAS 1 month, 3 months and 6 months after treatment were improved compared with those before treatment in the three groups ( all <0.05), and the MAS results in the dynamic scalp acupuncture group were better than those in the PNF and scalp acupuncture group (all <0.05). The FMA and BI scores 1 month, 3 months and 6 months after treatment were higher than those before treatment (all <0.05). The FMA Scores in the 3 time points and after treatment in the dynamic scalp acupuncture group were higher than those in the other two groups (all <0.05).

CONCLUSIONPNF therapy during scalp acupuncture can relieve the spasmodic condition of patients with upper limb motor impairment in ischemic post-stroke spasmodic hemiplegia, and improve the limb function and life activity, which is better than PNF therapy after scalp acupuncture and simple PNF therapy.
