Chinese Journal of Trauma 2009;25(9):826-828
Objective To investigate the clinical characteristics of clavicular defect and nonunion after operation and evaluate the clinical effects of vascularized pedicled pectoralis major clavicular periosteal flap and locking plate fixation plus bone morphogenetic protein (BMP) implantation. Methods From January 2004 to April 2008, 12 patients (mean age, 42.8 years old) with clavicular defect and nonunion were treated in Zhongshan Hospital. The internal fixators were removed, and then fibrous scars and sclerotic bones were cleared. The clavicular detects were fixed with locking plate, with implantation of the BMP. The wound was covered with vascularized pedicled pectoralis major clavicular periosteal flap. Postoperative functional rehabilitation exercises were performed. Results All patients were followed up for 8-24 months (mean 1.2 years). The clinical results were evaluated by Constant-Murley scoring system. The clavicular defects were healed in all patients within 4-7 months, and the internal fixators were successfully removed from some of the patients. Conclusions Vascularized pedicled pectoralis major clavicular periosteal flap combined with locking plate fixation plus BMP implantation is effective in the treatment of clavicular defect and nonunion.

Chinese Journal of Minimally Invasive Surgery 2014;(10):903-905
Objective To analyze the clinical effects, as well as its advantages and disadvantages, of laparoscopic surgery for appendicitis in obese patients. Methods Clinical data of 80 obese patients receiving appendectomy, including 38 cases of open appendectomy and 42 cases of laparoscopic appendectomy, were analyzed retrospectively.The operative time, blood loss, analgesic and antibiotic use, postoperative fever, postoperative complications, length of hospital stay, and hospitalization cost were compared between the two operative methods. Results Conversions to open surgery were required in 2 patients in the laparoscopic group. There was no significant difference in operative time between the 2 groups (P >0.05).Compared with the open group, the laparoscopic group had less blood loss [(14.98 ±12.77) ml vs.(31.58 ±19.00) ml, t=-4.550, P=0.000], shorter time of postoperative antibiotic use [(2.7 ±1.0) d vs.(4.1 ±1.2) d, t=-5.470, P=0.000], less postoperative analgesics needed [5.0%(2/40) vs.26.3%(10/38),χ2 =6.802, P=0.009], less drainage [2.5% (1/40) vs.18.4% (7/38), χ2 =5.367, P=0.021], less postoperative fever [5.0%(2/40) vs.23.7%(9/38),χ2 =5.616, P=0.018], less postoperative wound healing [5.0%(2/40) vs.21.1%(8/38),χ2 =4.493, P=0.034], and shorter hospital stay [(5.9 ±3.2) d vs.(8.7 ±4.1) d, t=-3.345, P=0.001], but the higher cost of hospitalization [(7800 ±396) yuan vs.(4914 ±434) yuan, t=30.716, P=0.000]. Conclusion For obese patients with appendicitis, laparoscopic appendectomy has less surgical trauma, faster recovery, less postoperative pain, fewer complications,and shorter hospital stay, being a preferred method of treatment.

Academic Journal of Second Military Medical University 2010;28(4):369-371
Objective: To study the pathological characteristics of columnar alteration with prominent snouts and secretions (CAPSS) and its relationship with incidence of breast carcinoma. Methods: One hundred forty-four CAPSS specimens identified by breast core needle biopsies(CNB) were retrospectively evaluated. The CAPSS specimens were subdivided into lesions with (n=108) and without (n=36) atypical ductal hyperplasia and their pathological findings were compared. Results: In situ and invasive carcinomas were found in 21.5% (31/144) of the specimens, including those with and without atypical hyperplasia. We also found that specimens with atypical hyperplasia had a higher malignant incidence than those without atypical hyperplasia (P=0.001). Conclusion: CAPSS, especially when with atypical ductal hyperplasia, are associated with breast carcinoma.

OBJECTIVETo investigate the morphology change of stomatognathic muscles after zygomatic plasty combined with mandibular angel plasty.
METHODS3D-CT facial soft tissue measurement was performed pre-operative and at 10 days,3 months post-operatively in 59 cases with prominent malar-complex and mandibular angle. The q test (Newman-Keuls method) was used to analyze the variance.
RESULTSThe cross sectional area of masseter muscle and medial pterygoid muscle were both increased at 10 days, reduced at 3 months post-operatively (P < 0.05). The masseter muscle and medial pterygoid muscle cross sectional areas were (4.73 +/- 0.21) cm2 and (3.24 +/- 0.21) cm2 at anterior nasal spine plane, respectively; the pterygoid muscle cross-sectional area was (1.37 +/- 0.35 ) cm2 at the root of coronoid process plane, showing significant difference, when comparing with those before operation (P < 0.05). Lateral pterygoid muscle and temporal muscle had no statistical difference between the pre-and 10 days post-operatively(P > 0.05), however, the temporal muscle was reduced while the lateral pterygoid muscle was increased at 3 months post-operatively. The temporal muscle cross-sectional area was(2.35 + 0.25) cm2 at coronoid process plane; the temporal muscle and lateral pterygoid muscle cross-sectional areas were (1.00 +/- 0.16) cm2 and (3.54 +/- 0.61) cm2 at the root of coronoid process plane, which were significantly different from those before operation (P < 0.05 ).
CONCLUSIONSBecause of osteotomy, muscles attached position are changed in the short term after zygomatic plasty combined with mandibular angel plasty. Masseter muscle and medial pterygoid muscle are inevitably injuried during the operation. With the postoperative recovery, muscles have adaptive changes which reduced compared with those before operation after their reattachment. Zygomatic plasty can cause temporal muscle atrophy;while the lateral pterygoid muscle is rarely involved, the cross sectional area had no statistical difference between the pre- and 10 days post-operative, and the cross sectional area increase at 3 months post-operatively may be due to a compensational enlargement.

Objective To analyze the clinical features of infective endocarditis with positive antineutrophil cytoplasmic antibodies ,and compare with ANCA associated small vessel vasculitis(AASV). Methods Three IE patients with positive ANCA were analyzed, and 13 cases from literatures were reviewed. Results Sixteen patients had positive anti-PR3 ANCA, in which 2 cases had both positive (anti-PR3 and anti-MPO ANCA) ANCA. All patients had some clinical manifestations mimic AASV, including fever ( 13/16, 81% ), rash (8/16, 50% ), rapidly progressive glomerulonephritis (7/16, 44% ), splenomegaly (6/16, 38% ). Streptococcal species were identified in 12 patients, and cardiac valvular abnormalities were demonstrated in all patients. All patients except 2, who died of cerebral hemorrhage followed by cerebral infarction, recovered with antibiotic therapy. Conclusion Infective endocarditis sometimes can have the same clinical features as AASV, so physicians should carefully differentiate between them when dealing with patients with positive ANCA antibodies.
