Objective To investigate the clinical application value of ultrasound-guided catheter drainage and vacuum-assisted Mammotome system in the treatment of lactational breast abscess. Methods The clinical data of 46 patients with lactational breast abscesses were analyzed retrospectively. All patients were divided into control group (28 patients) and treatment group (18 patients). Homemade irrigation and drainage tube was used in control group,and vacuum-assisted Mammotome system was used in treatment group. The curative effect of 2 groups was compared. Results All patients were cured. The mean healing time in treatment group was (9.5 ± 1.3) d,in control group was (12.5 ± 2.2) d, and there was significant difference (P < 0.01). The rate of breast-feeding in control group was 57.1% (16/28), in treatment group was 13/18,and there was no significant difference (χ2=1.069, P>0.05). All patients recovered well without recurrence. Conclusions Ultrasound-guided catheter drainage should be employed as first line treatment of breast abscess with diameter greater than the 3 cm. If patient′s economic conditions are good and have high requirement on the beauty outcome, vacuum-assisted Mammotome system can be applied as treatment option.

Kaino-sinus syndrome is one new complication of endoscopic sinus surgery. The patient had an operation of endoscopic surgery, because he was suffered from an illness of frontal nasal inverted papilloma again. After operation he was suffering pain in left epicanthal folds and frontal part, and had dry scab in nasal cavity when he breathed cold air. The symptoms could relieve by blocking prenaris. We found he had a big aperture of frontal sinus and dry scab in nasal endoscopic examination. His symptoms disappeared after cleaning and washing accessory nasal cavity by salt water.

Objective To investigate the changes in gastric intramucosal pH (pHi) and the effect of propofol on microcirculatory perfusion after myocardial ischemia-reperfusion injury in rabbits. Methods Twenty healthy adult rabbits of both sexes, weighing 2.0-2.7kg were randomly divided into two groups: A control group (n=10) and B propofol group (n = 10) . The animals were anesthetized with 2% sodium pentothal iv. Anesthesia was maintained with intermittent iv boluses of fentanyl and vecuronium. The animals were tracheotomized and mechanically ventilated during fluid and propofol infusion. PaCO2 was maintained at 35-40 mm Hg. Right internal jugular vein was cannulated for fluid and propofol infusion. Left carotid artery was cannulated for BP and HR monitoring and blood sampling. TRIP tonometry catheter (14F) was placed in the stomach. Lactated Ringer's solution was infused at 6-8 ml-kg-1 h-1 during experiment. In group B propofol was infused at 5mg-kg-1-h-1 when BP and HR were stabilized for 10 min, chest was opened and heart exposed. Left anterior descending artery (LAD) was tied for 60 min and then released for reperfusion. Hemodynamics and pHi were measured before myocardial ischemia (T0) , 60 min after myocardial ischemia (T1), 60 min (T2), 90min (T3) and 180min (T4) after reperfusion was started. Results There was no significant difference in BP and HR from T0 to T4 between the two groups. pHi decreased significantly after myocardial ischemia-reperfusion injury in both groups. pHi was significantly lower at T3 in propofol group than that in control group (P

OBJECTIVE To investigate the feasibility of determining the maximum comfortabl level by using the acoustically evoked stapedius reflex threshold via cochlear implant. METHODS Eleve cases of Nucleus C124 cochlear implant recipients operated in our hospital were selected(8-39 years old, who can decide TIC value by themselves with the postoperative time ranging from device initiation to 1 year after operation),of those four cases were diagnosed as bilateral large vestibular aqueduct syndrome,1 case as common cavity dysplasia,.neural response telemetry of these five patients with inner ear dysplasia were very high or barely measurable.Real-MCL level and acoustically evoked stapedius reflex threshold under activated condition were measured respectively. The stimulating sound was 110dB of white noise.RESULTS The two group values of ASRT and real-MCL were found to be consistant .There is no significant difference statistically (P>0.05). The thresholds of ASR increase with the increasing of real-MCL at the beginning of device initiation. CONCLUSION The acoustically evoked stapedius reflex threshold may reflect (ASRT) the maximum comfortable stimulation level under activated conditions in patients with cochlear implants.it is simple, reliable and may be used to determine the MCL of child cochlear implanted patients.

Objecttive To investigate the possibility of repairing articular cartilage defects with the mesenchymal stem cells (MSCs)- seeded type Ⅰ collagen-glycosaminoglycan(CG) matrices after being cultured with the chondrogenic differentiation medium.Methods The adherent population of MSCs from bone marrow of 10 adult dogs were expanded in number to the 3rd passage. MSCs were seeded into the dehydrothennal treatment (DHT) cross-linked CG matrices; 2 × 106 cells per 9-mm diameter samples were taken.Chondrogenic differentiation was achieved by the induction media for 3 weeks. Cell contractility was evaluated by the measuement of the cell-mediated contraction of the CG matrices with time in culture. The in vitro formation of the cartilage was assessed by an assay employing immunohistochemical identification of type Ⅱ collagen and by immunohistochemistry to demonstrate smooth muscle actin (SMA).The cells seededing CGs were implanted into cartilage defects of canine knee joints. Twelve weeks after surgery, the dogs were sacrificed and results were observed. Results There was significant contraction of the MSCs-seeded DHT cross-linked CG scaffolds cultured in the cartilage induction medium. After 21 days, the MSC-seeded DHT cross-linked matrices were contracted to 64.4% ± 0.3%; histologically, the pores were fotmd to be compressed and the contraction coupled with the newly synthesized matrix, transforming the MSCsseeded CG matrix into a solid tissue in most areas. The type Ⅱ collagen staining was positive. The SMA staining was positive when these MSCs were seeded and the contracted CGs were implanted into the cartilage defects of the canine knee joints to repair the cartilage defects. The function of the knee joints recovered and the solid cartilaginous tissue filled the cartilage defects. Conclusion The results demonstrates that MSCs grown in the CG matrices can produce a solid cartilaginous tissue containing type Ⅱ collagen after being cultured with the chondrogenic differentiation medium and implanted into cartilage defects. We hypothesize that the following steps can be performed in the chondrogenic process: ①MSCs express SMA, resulting in matrix contraction, thus achieving a required cell density (allowing the cells to operate in a necessary society); ②Cells interact to form a type Ⅱ collagen-containing extracellular matrix (and cartilaginous tissue); ④Other factors, such as an applied mechanical stress, may be required to form a mature cartilage with the normal architecture.
