Objective:To observe the clinical efficacy of skin needling plus heat-sensitive moxibustion in treating chronic facial paralysis. Methods:Sixty patients with chronic facial paralysis were divided into an observation group and an acupuncture group by using the random number table, 30 in each group. Patients in the observation group were given skin needling plus heat-sensitive moxibustion; while patients in the acupuncture group were given conventional acupuncture. Results:Three treatment courses later, the total effective rate was 93.3% in the observation group versus 86.7% in the control group, and the difference was statistically significant (P<0.05). Conclusion:Skin needling plus heat-sensitive moxibustion can produce a more significant efficacy than conventional acupuncture in treating chronic facial paralysis.

Objective To study the clinical value of mammography and ultrasound needle localization biopsy technique in clinical nonpalpable breast disease.Methods 148 patients with negative clinical palpation were operated only because of the mammography or ultrasound findings of lesions.They were undergone localized excision biopsy and derived definite pathological diagnosis.By histopathology diagnosis,benign and malignant lesions,lesion size,complete resection rate were statistically analyzed.Results 21 cases in 148 cases were malignant lesions(14.2％),which were all early breast cancer.The other 127 cases were benign breast disease(85.8％).147 cases were successfully resected at the first time and 1 case was successfully resected at the second time.Conclusion Mammography and Ultrasound fine needle localized biopsy in nonpalpable breast disease diagnosis and treatment has great significance,which can raise early diagnosis rate of breast cancer without mass,and this method is simple and easy for promotion.

Objective To analyze the relationship of clinicopathologic Features and prognosis of triple negative breast cancer. Methods A total of 196 cases with operable breast cancer received in our hospital between January 2002 and February 2007 were analyzed. We used immunohistochemistry to determine Her2, ER, and PR status. The patients were divided into the triple negative breast cancer group (ER negative,PR negative, and Her-2 negative)and the non-triple negative breast cancer group. The clinicopathologic features of the two groups were compared. The 3-year disease-free survival (DFS) was analyzed. Results Of the 196 patients, 13.27% (26/196) had triple negative breast cancer. The percentage of cases with tumor exceeded 5 cm or grade Ⅲ was higher in the triple negative group than in the non-triple negative group (P ＜ 0.05 ). No significant difference was found in other clinicopathologic features between the two groups.The 3-year DFS was 84.62% (22/26) in the triple negative group and 92.94% ( 158/170)in the non-triple negative group. Conclusion Compared with non triple negative breast cancer, triple negative breast cancer has an increased possibility of local recurrence or distant metastasis,leading to a poorer prognosis.

Objective To establish a novel direct radio-labeling method for 99Tcm-IgG and evaluate the biologic distribution of 99Tcm-IgG.Methods IgG protein was modified with 2-mercaptoethanol.Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE),UV-vis spectrophotometer,matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) were used to identify the concentration,integrity of the modified protein.Then radiolabeled IgG-SH with 99TcmO4-was analyzed with radio-HPLC.The product was prepared as frozen kits.The distribution and metabolic process of 99Tcm-IgG were observed in New Zealand white rabbits.Results The relative molecular mass of IgG-SH and IgG measured by SDA-PAGE were similar.The relative molecular mass measured by MALDI-TOF was 1.47× 105.The radiolabeling yield was over 95％,the specific activity was 1.7× 105 GBq/mmol.All the radioactive conjugates of 99Tcm-IgG showed excellent stability in vitro.And more than 95％ conjugates retained their original structures for 6 h in 5％ BAS.Gamma imaging in New Zealand white rabbits showed blood retention in first 4 h after injection,and prominent uptake of radiotracers in the liver,kidneys,and urinary bladder at 24 h after injection,which indicated that 99Tcm-IgG was excreted mainly through the renal route.99Tcm-IgG kept its original biological activity after the modification.Conclusions Direct radio-labeling of 99Tcm-IgG was successfully established.The methods may be useful for radio-modification of monoclonal antibody.

Objective To explore a new method for improving healing of skin graft donor sites.Methods A total of 40 patients who needed intermediate thickness skin graft from thigh,from January 2014 to December 2015,were randomly devided into experiment group and control group.Skin graft donor sites of the experiment group were covered with Physiotulle Ag and Allevyn foam dressing,while donor sites of the control group were covered with petrolatum impregnated gauze,sterile gauze,and compression bandage.Postoperative infection rate,pain scoring during the first dressing change,time of dressing change between operation and complete healing,duration for complete healing,and the area of non-healing two weeks after operation were compared and statistical analysis was performed with SPSS17.0.Results There was no infection in the experiment group.Two patients developed infection in the control group,with wound exudate culture positive for pseudomonas aeruginosa,and the wounds healed after dressing change.The experiment group was significantly better than that of the control group in pain scoring during the first dressing change,time of dressing change between operation and complete healing,duration of complete healing (U=81.5,P=0.001;U=109.5,P=0.011;t=0.769,P＜0.001).Conclusions The Physiotulle Ag combined with Allevyn foam dressing can enhance healing of skin graft donor sites,alleviate pain of the patient,and reduce dressing change.This method is easy to perform,and skin graft donor sites heal well in two weeks,which may lead a prospected application.

Objective To analyse the effect of holmium laser incision through ureteroscopy and simple ureteroscopy treatment for refrac-tory hemospermia. Methods From December 2003 to April 2013,the data of 67 cases with refractory hemospermia were retrospectively ana-lyzed. All the patients underwent semen analysis,transrectal ultrasonography,seminal vesicle ultrasonography,some patients underwent pelvic CT or MRI. Results Simple ureteroscopy were done for 24 cases,holmium laser incision through ureteroscopy were done for 43 cases. Var-ying degrees of ejaculatory duct stenosis or obstruction were observed. Postoperative follow-up was from 6 months to 8 years,in 24 cases of simple ureteroscopy,2 cases experienced recurrence 6 or 8 months later. The ejaculatory duct narrow were found when they received reopera-tion,with holmium laser incision,hemospermia disappeared. No complications such as retrograde ejaculation,urinary incontinence or rectal injury occurred postoperatively. Conclusion The effect of holmium laser incision through ureteroscopy for refractory hemospermia is better than simple ureteroscopy,which is worthy of clinical application needs further observation and summary.

Objective To monitor and compare the breathing mechanics on PC,VC and PRVC during pneumoperitoneum,and to discuss the significance of the clinic use of PRVC.Method Ninety laparoscopic cholecystectomy patients were equally divided into 3 groups (PC,VC,PRVC).Levels of PES,PAWM,PAP,PaCO2,ETCO2,TV MAP and HR were detected before pneumoperitoneum,and at 5,10,15 and 20 minutes postpneumoperitoneum.Results Pneumoperitoneum made three respiratory patterns with different levels of PAWM,PAP,and PES.PES post-pneumoperitoneum in the VC model was obviously higher than that in the PC and PRVC group.At 10 min post-pneumoperitoneum,levels of PaCO2 and ETCO2 increased obviously in the PC and VC group(P ＜ 0.05).Levels of PaCO2 and ETCO2 were increased in the PC group,but TV level post-pneumoperitoneum was significantly lower than that in the other two groups (P ＜ 0.05).Level of PaCO2 and ETCO2 were increased in the PC and VC group post-pneumoperitoneum,along with increases of MAP and HR (P ＜ 0.05).Levels of MAP and HR in the PRVC group post-pneumoperitoneum were significantly lower than those in the PC and VC group (P ＜ 0.05).Conclusion PRVC mode can effectively reduce the increases of pneumoperitoneum-induced PAWM,PAP,PES,without the unusual increase of PaCO2 and ETCO2 during surgeries,contributing to the stability of vital signs of perioperative patients.

Objective To evaluate the efficacy and safety in the treatment for gravitation wrinkles and unsatisfied shape with raonopolar and bipolar radiofrequency (RF) technique. Methods 28 patients were enrolled in this study. Every patient was treated for four times with an interval of 14 days by Accent Pro radiofrequency electric device (Alma Lasers Ltd). The clinical photographs were taken before and after the treatment, and the parameters were recorded during the treatment. The clinical efficacy and safety was evaluated 1 month after the treatment by comparing photographs and patients' satisfaction. Results Satisfactory rates were as follows: 85 % in doctor side, and 90 % in patients' side. No blister, scald, pigmentation and scar were observed during the treatment. Conclusion High frequency electric technique can be effective for the treatment of gravitation wrinkles and skin tightening by heating tissue deeply and non-invasively. Our clinical study shows that RF is an effective, non-invasive treatment with less pain and low side effects.

BACKGROUND:Negative pressure wound therapy has been widely recognized, the currently published papers are limited in academic value and lack of scientific, objective, qualified index to confirm the therapy effectiveness. OBJECTIVE:To systemical y evaluate the clinical effect of negative pressure wound therapy, provide more evidence for its clinical application, and guide clinical research.
METHODS:Fifteen articles were screened out of peer-reviewed publications (Cochran library, Embase, PubMed-Medline and Chinese BioMedical Literature Database). Scientific data were col ected and evaluated by two researchers. The data were statistical y analyzed with RevMan software.
RESULTS AND CONCLUSION:Only 15 random-control ed trials were final y preserved, including 10 as B-grade moderate bias risk and focused on the effect of negative pressure wound therapy on chronic wounds, and 5 as C-grade high bias risk and focused on the effect of negative pressure wound therapy on acute wounds. There were significant differences in the main outcome measures between negative pressure wound therapy and conventional wound therapy. As for chronic wound patients, no significant difference was observed in the operation-preparing period, reducing wound area, promoting wound granulation, and amputation rate between two therapies. As for acute wound patients, the differences were significant in the operation-preparing period, promoting wound granulation, wound infection rate, and cost materials between two therapies. However, no difference was significant in the healing of wound and hospitalization time. Our findings indicate that, negative pressure wound therapy is an effective means for both acute and chronic wounds, it can shorten operation-preparing period, promote wound granulation, and reduce amputation rate and infection rate, thus providing evidence for clinical application. The wel-designed study is needed to develop high-quality random control ed trails.

BACKGROUND:Negative pressure wound therapy has been extensively used, but most people only knew the superiority of negative pressure wound therapy based on clinical experiences or subjective judgment.
OBJECTIVE:To observe the effects of negative pressure wound therapy on the wound on the body surface, and to compare with contemporaneous conventional method.
METHODS:A total of 45 patients with wound on the body surface treated in the Peking Union Medical Col ege Hospital from January 2006 to December 2011 were enrol ed in this study, including 25 patients undergoing negative pressure wound therapy and 20 patients undergoing conventional change dressing method. Al clinical data were recorded.
RESULTS AND CONCLUSION:Negative pressure wound therapy was better than conventional method (P<0.05), on terms of preoperative preparation period, wound granulation, bacterial scavenging, labor intensity of working staff and incidence of postoperative complications. However, no significant difference in therapy cost was detectable (P>0.05). These results suggested that compared with conventional method, negative pressure wound therapy positively contributed to the healing, obviously shortened preoperative preparation, accelerated the diminution of wound, decreased the incidence of complications of reconstruction, lessened patient’s distress, reduced their economic cost, and diminished labor intensity of working staff. Negative pressure wound therapy has been proven an excellent tool of to promote wound healing.
