Objective To compare the clinical efficacy of breast-conserving surgery and modified radical mastectomy for early breast cancer and their influence on quality of life.Methods 78 patients with early stage breast cancer were divided into two groups by random number table,and 39 cases in each group.The control group was given modified radical mastectomy,while the observation group was given breast-conserving surgery.The clinical efficacy,surgical conditions and quality of life scores were compared between the two groups.Results The operative time,blood loss,incision length and the average hospital stay of the observation group were (60.23 ± 5.21)min,(44.73 ± 4.22) mL,(4.72 ± 1.02) cm and (9.52 ± 0.86) d,which were significantly lower than those of the control group(t =7.88,8.32,8.89,6.42,all P ＜ 0.05).The postoperative physical factors,mental factors,psychological factors and social factors scores of the observation group were (67.44 ± 3.87),(48.64 ± 3.73),(117.34 ± 8.33)and (61.56 ± 5.32),which were significantly higher than those of the control group (t =5.43,5.87,6.29,7.11,all P ＜ 0.05).The postoperative 3-year local recurrence,distant metastasis and survival rate showed no significant differences between the two groups (x2 =1.22,1.09,1.29,all P ＞ 0.05).Conclusion Breast-conserving surgery in the treatment of early breast cancer has significant effect,and it has less trauma,less bleeding and cosmetic results,and it can be used as the preferred method for the treatment of early breast cancer,which is worth to be further applied in clinical.

AIM: To explore the curative effects of various approaches to improve the arterial inflow following flap grafting with various tensions. METHODS: 135 patients with skin defects in limbs, who underwent flap grafting in Department of Orthopedics, Baoan People's Hospital of Southern Medical University between August 2002 and August 2006, were selected, and informed the consent. The wounds of every 45 cases were sutured under the tension of 1.0 kg, 1.5 kg, and 2.0 kg, respectively; meanwhile, all patients were randomly divided into hyperbaric oxygen group, dexamethasone group, and local injection of heparin group with 15 cases in each group, and given the corresponding treatment besides ordinary treatment. Seven days later, the flap survival was observed. RESULTS: 135 patients were all involved in the result analysis without any loss. The flaps of 90 patients recovered completely under the tension of 1.0 kg and 1.5 kg. But under 2.0 kg tension, the flaps of 10 penitents in the hyperbaric oxygen group recovered, 4 survived mostly and 1 necrosed; in the dexamethasone group, 5 flaps recovered, 3 survived mostly, and 7 necrosed; in the local injection of heparin group, 3 flaps recovered, 3 survived mostly, other 9 necrosed completely. CONCLUSION: The suture tension of 1.0 kg to 1.5 kg is feasible in flap grafting, and compared with heparin and dexamethasone, hyperbaric oxygen could better promote the arterial inflow under high tension like 2.0 kg.

Objective To analyze the clinical feature and its risk factors on 112 episodes of urinary tract infection (UTI) in patients with lupus nephritis. Methods 112 episodes of UTI in patients with lupus nephritis in our department during the past 5 years were reviewed retrospectively. Epidemiological data and information on urinary symptoms, disease activity (SLEDAI) , leukocyte and platelet data were collected. Autoantibodies, complement levels, urine culture, and antibiogram were determined. Urological studies were carried out. The use of corticosteroids and (or) immunodepressive were also investigated. Results The prevalence of UTI in lupus nephritis patients was 36.5% , and complexity infection(58%) was the main UTI . Symptomatic UTI was 62% , and symptomless UTI was 38% . The mean SLEDAI score was 15.7(SD3.05) , which influenced the onset of UTI (P1/100 IU/ml, leucopenia and thrombocytopenia (P

ⅡB. Our investigation also showed that the activity of PAS, LDH and PFK was stronger in type Ⅱ fibers than in type Ⅰ. It was concluded that each type fibers in the rat plantaris exhibit significant differences in metabolic and functional activity. The type ⅡA fibers present both high activity of glycolytie enzyme and oxidase, and reflect that these enzymes may play very important role in energy metabolism. Further study remains to bedertaken.

Objective To compare the operative efficacy of low collar incision and L-shaped incision plus cervical plexus preser-ving lymphadenectomy in treating papillary thyroid carcinoma.Methods 9 3 inpatients with papillary thyroid carcinoma were ran-domly divided into the low collar incision group (n=37)and the L-shaped incision group(n=56)according to the random number table.The low collar incision group underwent the low collar type cervical plexus preserving lymphadenectomy,while the L-shaped incision group received the L-incision cervical plexus preserving lymphadenectomy.The postoperative 24-month follow up was per-formed.Then the clinical efficacy and the life quality of the patient were evaluated and compared between the two groups.Results (1)1 case of lymph node recurrence in the district Ⅱ after 20 months was found in the low collar incision group,1 case of lymph node recurrence in the district Ⅰ after 12 months and 1 case of lymph node recurrence in the districtⅣ after 22 months was found in the L-shaped incision group;no case of distant metastasis in the low collar incision group occurred during the follow up period, but 1 case of pulmonary metastasis in postoperative 5 months and 1 case of bone metastasis in postoperative 24 months occurred in the L-shpaed incision group.The differences in the occurrence rates of postoperative recurrence and metastasis had no statistical sig-nificance (2.70%vs.7.14%).(2)The scores of neck shoulder pain and numbness,incision appearance satisfaction degree in the low collar incision group were significantly higher than those of the L-shaped incision group (P<0.05).Conclusion Compared wtih L-shaped incision cervical lymphadenectomy,low collar incision cervical plexus preserving cervical lymphadenectomy has simi-lar high clinical efficacy,can significantly reduce neck shoulder pain and numbness,meet aesthetic requirements and especially is suitable for the patients with higher demands of the neck function preserving and the neck appearance.
