ABSTRACT
OBJECTIVE@#To explore the factors affecting the successful rate of nano-carbon in sentinel lymph node biopsy. @*METHODS@#A total of 270 patients with breast cancer, who were treated in First Affilitated Hospital of Henan University of Science and Technology from January 2013 to March 2015, were chosen and given sentinel lymph node biopsy (SLN) with nano-carbon, and the influencial factors were examined by logistic analysis. @*RESULTS@#Successful rate of biopsy, accuracy, sensitivity and false negative rate was 92.2%, 97.6%, 93.1% and 6.8%, respectively. Age, primary tumor lesions, body mass index, axillary lymph node status, number of SLN and pathological grade were the factors affetcing successful biopsy (all P 0.05). @*CONCLUSION@#Nano-carbon tracer method is a reliable method in sentinel lymph node biopsy. The body mass index, age, and number of lymph node metastasis greatly impact the successful rate of biopsy.

Objective To investigate the methods and effects in repairing fracture of the fifth metatarsal base bone with Acutrak headless compression screws.Methods From May 2006 to October 2012,75 patients with fracture of the fifth metatarsal base bone were reduced and fixed using Acutrak headless compression screws.There were 38 males and 37 females with a mean age of 36 years (range,21-65 years).Injury arose from fall from height (35 cases),road traffic accidents (23 cases),and fall of heavy objects (17 cases).Fracture of the left foot occurred in 29 cases and the right foot in 46 cases.Results were evaluated using American Orthopedic Foot and Ankle Society (AOFAS) ankle and midfoot score.Results Seventy-two patients were followed up for mean 15 months (range,13 months5 years).Operative incision obtained primary healing without any complications.Mean AOFAS ankle and midfoot score increased to (93.0 ± 6.5) points (range,79-100 points) at postoperative 1 year,compared with the preoperative (28.0 ± 3.9) points (range,0-42 points) (t =7.650,P ＜ 0.05).Muscle force and valgus or abduction of mid-forefoot of the affected and unaffected sides demonstrated no significant difference after operation.Conclusion Acutrak headless compression screw system shows advantages of rigid fixation,few complications,and early healing in treatment of the fifth metatarsal base fracture.
ABSTRACT
Lumbar spinal stenosis [LSS] is a usual condition for spinal surgeries among adults over 65 years old. We conducted the present study to evaluate the health-related quality of life [HRQoL] after LSS in a group of Chinese patients. We followed up 79 patients who received surgeries for LSS for one year. The HRQoL before treatment and one year after treatment was evaluated with the Medical Outcome Short Form 36 [SF-36]. The HRQoL of patients after LSS significantly improved in three mental health domains [social function, vitality and mental health] and all four physical health domains one year after surgical treatments. However, patients with TBI still had significant lower scores in every domain than the reference group even one year after discharge. The HRQoL had lower scores at discharge greatly improved one year after the treatment. This study also highlighted the usefulness of the HRQoL assessment for prognosis evaluation in patients after surgical treatment for LSS
ABSTRACT
BACKGROUND:Pain is the extremely common disease in clinic. At present, acupuncture provides good therapeutic effect on it. But, there are many methods in acupuncture with various advantages individually.To understand the differences in therapeutic effects on pain with various needling techniques is significant in clinic. In 1999, the relevant observation was carried on in the demand of Ecuadorian Medical Pain Association.OBJECTIVE: To observe the differences in therapeutic effects on pain with various needling techniques.DESIGN: Randomized controlled observation was designed.SETTING: Department of Pain, Hospital General de las FF. AA. Quito, Ecuador, Department of Traditional Chinese Medicine and 1st Department of Surgery, General Hospital of Chengdu MilitaryArea Command of Chinese PLA.PARTICIPANTS: Totally 360 cases of lumber strain and hyperplastic spondylitis were selected in Department of Pain, Clinic of Ecuadorian 3rd Military General Hospital from May 1999 to November 2000, in which,179 cases were lumber strain and 181 cases were hyperplastic spondylitis.The groups were randomized in two kinds of diseases, named for lumber strain, dermal-needling group (88 cases) and body-acupuncture group (91cases); for hyperplastic spondylitis, dermal-needling group (92 cases) and body-acupuncture group (89 cases).METHODS: Dermal needling and body acupuncture were used to treat the diseases respectively and the symptom changes were observed before and after treatment simultaneously. The treatment was given once every two days. 5 treatments made one basic course for lumber strain and 7 treatments for hyperplastic spondylitis. The treating results were evaluated according to Budzynski grading criteria on pain. MEPS statistical software was used for statistical management of data.MAIN OUTCOME MEASURES: Pain relieving before and after treatment with dermal needling and body acupuncture for lumber strain and hyperplastic spondylitis was evaluated. Correlative analysis on therapeutic effects and course of treatment for different diseases with same therapy and on same disease with different therapies were carried on.RFSULTS: Altogether 366 cases were observed and 6 of them were excluded. Totally, 360 cases finished the experiment. ① The severity was alleviated in pain grading after treatment with dermal needling and body acupuncture compared with that before the treatment (P ＜ 0.01). ② In treatment of lumber strain and hyperplastic spondylitis with dermal needling, the therapeutic effects on lumber strain were more remarkable (P ＜ 0.01). The therapeutic effects of dermal needling on lumber strain were superior to that of body acupuncture (P ＞ 0.05). ③ The therapeutic effects of body acupuncture group on pain of Ⅰ grade in hyperplastic spondylitis were remarkably better than that of dermal needling group,but the significant difference in the total therapeutic effects of two techniques did not present (P ＞ 0.05). ④ When pain grading was reduced by 1 level in two groups, the average times of treatment in dermal needling group were less than that in body-acupuncture group (P ＜ 0.05).CONCLUSION: Good therapeutic effects of dermal needling and body acupuncture are achieved for both hyperplastic spondylitis and lumber strain,in which, the therapeutic effects of dermal needling are remarkable on injury of soft tissue and achieved swiftly; body acupuncture improves pain in hyperplastic spondylitis more radically compared with dermal needling.
ABSTRACT
Objective To provide a reliable model of orthotopic liver transplantation in rats and study surgical techniques for improving the quality of the operation. Methods The model was established by modified Kamada’s cuff technique. The time of cold preservation was 60 min. The successful rate of the method and one-week survival rate were observed. Results In 135 cases undergoing orthotopic liver transplantation, one-week survival rate was 89.2% . The successful rate of the model was 95.6% . Conclusions The key for success in rat liver transplantation is the shortened anhepatic period and delicate and skillful surgical manipulation. Also some detailed modified techniques should be used.
ABSTRACT
Objective To study the liver injury and effects of aescin on liver in rats with acute pancreatitis. Methods The rats were divided into 3 groups (control group, AP group and aescin group). The serum alanine aminotransferase (ALT), serum lactate dehydrogenase (LDH), hepatic cellular energy charge (EC) and adenosine triphosphate (ATP) were detected. The pathologic changes in pancreas and liver were also observed. Results The serum levels of ALT and LDH in aescin group were significantly lower than those of the AP group. The EC and ATP levels were significantly higher in aescin group than that of the AP group. Conclusion Introvenous injection of aescin can alleviate the liver injury in rats with acute pancreatitis.
