The data of 173 cases with acute mastitis were collected and reviewed from January 2010 to October 2012.The liquor puris samples were collected for bacterial culture.And drug sensitive test was performed by Kirby-Bauer method.98 samples were cultured with a positive rate of 56.7％.A total of 98 bacterial strains were isolated,Gram-positive bacteria were 91 strains (92.9％) and Gram-negative 7 strains (7.1％).The most common bacteriun Staphylococcus aureus,accounted for 83.7％ was highly resistant to penicillin and erythromycin with resistant rates of 90.2％ and 86.6％ respectively.And there was no resistance to vancomycin and teicoplanin.

Objective:To investigate the relationship between the expression of P16 protein and the clinico-pathology of squamous cell carcinoma(SCC) of buccal mucosa and its precursor lesions. Methods:The immunohistochemical stain against p16 was performed in 30 cases of SCC of buccal mucosa, 32 cases of buccal leukoplakia and buccal lichen planus and 10 cases of normal buccal mucosa. All data were analyzed quantitatively by imag analysis technique. Then, the results were compared with clinico-pathological parameters.Results:The positive expression of P16 protein was found in all normal buccal and hyperplasia mucosa (100.0%), in 9 out of 10 cases of atypical hyperplasia (90.0%), in 12 out of 30 cases of SCC of buccal mucosa (40.0%). The positive expression rate of P16 protein in SCC of buccal mucosa was significantly lower than that in atypical hyperplasia (P

Objective: To understand the effects of different expansion ways on collagen and actin of skin and to provide an experiment foundation for the suitable expansion method clinically. Methods: The rabbits were divided into five groups. The expanders were embedded in experimental group. The sirius-red specific staining method was applied to observe the changes of type I collagen and type III collagen and their proportion. Immunochemistry method was used to detect the expression of actin. Results: 1: In group A, B and C, type I collagen arranged turbulently and was thicker and type III collagen decreased relatively at earlier maintaining period. After 4 week, type I collagen arranged regularly and type III collagen was relatively increased. 2: Comparisons of the area about type I, III collagen: At the same maintaining period, there were no significant difference among the group A,B and C. With the extension of maintaining period, the area of type I, III collagen increased gradually, but there was inclined to stabilize at the fourth week in group A, B and at the third week in group C. Comparison of the proportion of collagen I and collagen III: There were significant difference between group A, B and group D, but no significant difference was observed after the fourth week. There were significant difference between group C and control group, but no significant difference was observed after three week. 3. With the extension of maintaining period, the positive expression rates of actin decreased gradually in group A, B, C. At the same maintaining period, significant difference were observed among group A, B, C. The positive expression rates of actin in group C were lower than that of group A at the same maintaining period. Conclusion: The repeated rapid expansion can not only shorten the clinical period but also promote the quality of skin flap. It is a safe and feasible method in clinic.

Objective To investigate the prevalence of thyroid disorders and positive thyroid autoantibodies,and evaluate the necessity for universal thyroid screening during the second and third trimesters of pregnancy.Methods The pregnant women during the second and third trimesters who visited Shanghai Jiaotong University Affiliated First People's Hospital between June 2006 and February 2008 were chosen for thyroid screening by determining serum free triiodothyronine,free thyroxine,thyrotropin,thyroid peroxidase antibody (TPOAb),and thyrotropin receptor antibody.A personal and family history of thyroid disease and other autoimmune diseases was investigated by questionnaire.The pregnant women were divided into high risk or low risk groups for thyroid disease based on their personal or family histories.Results A total of 2 101 pregnant women were screened,712 ( 33.89％ ) of them were identified to suffer from thyroid disorders or with positive thyroid autoantibody.The prevalence of thyroid dysfunction was increased in high risk group.While in low risk group( n =1 983 ),the prevalence of clinical hypothyroidism was 2.27％ ( n =45 ),subclinical hypothyroidism 11.60％ ( n =230 ),clinical hyperthyroidism 0.20％ ( n =4 ),subclinical hyperthyroidism 1.06％ ( n =21 ),hypothyroxinemia 6.45％ ( n =128 ),and euthyroid with positive TPOAb 10.74％ ( n =213 ) in our study.Pregnant women with positive TPOAb were susceptible to thyroid dysfunction.It was shown that 79.74％ of pregnant women with thyroid disorders were diagnosed by universal thyroid screening.Conclusions 33.89％ of pregnant women in the second and third trimesters were identified to suffer from thyroid disorders or positive thyroid autoantibody by universal thyroid screening.Increased prevalence of thyroid dysfunction was found in pregnant women with positive TPOAb.79.74％ of pregnant women with thyroid disorders might be missed if screening was made only in the high risk cases.

ObjectiveTo investigate the influence of positive serum thyroid peroxidase antibody (TPOAb) on pregnancy outcomes in biochemically euthyroid women during gestation.MethodsFrom July 2006 to December 2010,in the prenatal care unit all pregnant women,who had no medical and family history of thyroid diseases,underwent thyroid function screening.Serum TPOAb was tested among those pregnant women with euthyroidism.Pregnancy outcomes,including obstetric complications,neonate birth weight,and Apgar score,were compared between 185 TPOAb positive women and 1417 TPOAb negative women.ResultsCompared with TPOAb negative women,it was more frequent for TPOAb positive women to suffer from various obstetric complications.The prevalences of umbilical cord entanglement ( 18.9％ vs 12.9％,RR =1.47,95％ CI 1.06-2.03,P＜0.05 ),threatened premature delivery or abortion (3.8％ vs 1.0％,RR =3.83,95％ CI 1.57-9.37,P＜0.05 ),intrauterine growth retardation (5.4％ vs 0.8％,RR =6.96,95％ CI 3.00-16.17,P＜0.01 ),and neonatal pneumonia ( 4.9％ vs 1.3％,RR =3.83,95％ CI 1.75-8.40,P＜0.01 ) in the group of TPOAb positive women were higher than those in the group of TPOAb negative women.Apgar score of those newborns whose mothers had positive TPOAb was 9.27 ±1.13 at one minute and 9.44 ± 1.09 at five minutes,being lower than that of the TPOAb negative group (9.49 ±0.69 and 9.68 ±0.52,both P＜0.01 ).The rate of newborns with Apgar score at 7 or less by 5 min in group with positive TPOAb was higher than that of group with negative TPOAb ( 1.6％ vs 0.1％,RR =11.49,95 ％ CI 1.93-68.31,P＜ 0.05 ).ConclusionsThese results indicate that pregnant women with normal thyroid function but positive TPOAb may be liable to increase risk of serious pregnancy outcomes,such as threatened premature delivery or abortion,intrauterine growth retardation,and a lower Apgar score in neonatal.

Objective To evaluate the effects of nurse-led team management on self-management and hyperten-sion control for community-dwelling hypertensive patients. Methods A quasi-experimental study design was adopt-ed,two communities were elected as the intervention group and the control group in Wuhou District,Chengdu,and 102 hypertensive patients were recruited from each group. The intervention group received nurse-led team manage-ment for 2 years,and intervention methods included individual management,phone or home follow-up,collective inter-vention and so on. While the control group received doctor-led hypertension management. The patients' self-man-agement behaviors and hypertension control were evaluated before the intervention and 6,12,24 months after the intervention. Results After 24-month nurse-led team management,scores of self-management behaviors and hyper-tension control rate of patients in the intervention group were significantly higher than those of patients in the con-trol group(P<0.05). Conclusion Nurse-led team management could significantly improve self-management behaviors and the rate of hypertension control for hypertensive patients.

Objective To investigate the clinical and pathological features of Guillain-Barré syndrome with treatment-related fluctuations ( GBS-TRF ).Methods Clinical data were obtained from medical records of patients with GBS-TRF during the period 1999 to 2014 in our Hospital.Sural nerve specimens were collected and summarized retrospectively ( two cases ).Results Eight of 868 cases with GBS had at least one TRF including three chronic hepatitis B patients.The onset of disease was ranged in age from six to 63 years, averaging 34 years.It is more common in men than in women in a ratio of seven:one.Triggering infections occurred in three patients.The initial symptom included weakness of the lower limbs ( five cases ) and upper extremities ( three cases ).Sensory symptom was presented in six patients.Five patients had associated respiratory paralysis.None of them had cranial nerve palsy or autonomic dysfunction.Five patients had two attacks , one had three attacks and two had six attacks.The interval between attacks ranged between 14 days and 46 days ( mean 23 days ).The striking pathologic finding was the presence of sectional selective nerve fiber degeneration ( SNFD ) with evidence of demyelination.Conclusions Patients with GBS-TRF shows similar onset age , preceding infection , cerebrospinal fluid findings, and electrophysiologic characteristics comparing to patients with GBS ,while there are more male patients than female patients.SNFD found in sural nerve biopsy reveals ischemic neuropathy , which predicts that injury of arterioles might play an important role in the pathogenesis of GBS -TRF.

ObjetiveTo investigate the obstetrical and neonatal outcomes of pregnant women with hypothyroidism or subclinical hypothyroidism.MethodsOne hundred and sixty-eight pregnant women with clinical or subclinical hypothyroidism during pregnancy,including 9 controlled hypothyroidism,29 uncontrolled hypothyroidism and 130 subclinical hypothyroidism,were enrolled in this study.The general clinical information,obstetrical complications and neonatal outcomes of these pregnant women were compared with that of 180 healthy pregnant women who delivered during the same period.ResultsCompared with control group,there were no significant differences in the levels of serum free triiodothyronine( FT3 ),free thyroxine ( FT4 ),thyrotropin-stimulating hormone (TSH) in the controlled hypothyroidism group in the third trimester [(3.68 ±1.11 ) pmol/L vs (3.19 ±0.33) pmol/L,(15.48 ±4.14) pmoL/L vs (13.95 ± 1.68) pmol/L,1.87 mU/L vs 1.76 mU/L,P ＞0.05].However,in the second and third trimester,the levels of FT3,FT4 in the uncontrolled hypothyroidism group were lower,while the levels of TSH were higher than in control group [(2.71 ±0.80) pmol/L vs (3.14 ± 0.34) pmoL/L,(10.94 ± 2.68) pmol/L vs (14.25 ±2.01) pmol/L,5.62 mU/L vs 2.28 mU/L,( 2.34 ± 0.70 ) pmol/L vs ( 3.19 ± 0.33 ) pmol/L,( 10.16 ± 1.65 ) pmol/L vs (13.95 ± 1.68) pmoL/L,7.13 mU/L vs 1.76 mU/L,t =2.754～9.15,P ＜0.01],the levels of TSH in the subclinical hypothyroidism were higher than in control group ( t =18.28,18.57,P ＜0.01 ).There was no adverse perinatal outcome of neonate happened in controlled hypothyroidism group.In contrast,the incidences of adverse perinatal outcomes and complications in the uncontrolled hypothyroidism group were higher than that in the control group ( 17.2％ vs 2.8％,37.9％ vs 5.6％,x2 =11.47,28.97,P ＜0.01 ).Compared with that of control group,the incidences of adverse obstetrical outcomes in pregnant women with subclinical hypothyroidism were increased (40.0％ vs 5.6％,x2 =52.97,P ＜ 0.01 ).ConclusionsThe rate of adverse obstetrical outcomes and complications is increased in women with clinical or subclinical hypothyroidism.But the incidence of adverse outcomes would decrease if hypothyroidism is controlled by treatment.
