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.

OBJECTIVETo analyze the effects of metacarpus and phalanx traction on correction of scar contracture of hand after burn on the palm side retrospectively.

METHODSA total of 32 patients with 39 affected hands with scar contracture on the palm side after burn were hospitalized from May 2010 to December 2014. Method of treatment: scar contracture was conservatively released followed by skin grafting, which was referred to as method A; Kirschner wire was inserted into the middle or distal phalanx of finger with contracture and the corresponding metacarpus in the shape of U for 2 to 7 weeks' traction, which was referred to as method B; traction frame was built based on the traction pile and anchor formed by Kirschner wire inserted through the second to the fifth metacarpus and distal phalanx of finger with contracture, and then the affected fingers were pulled into a straight position with rubber bands for 2 to 6 months, which was referred to as method C. Method A was used in patients who would be treated with thorough release of scar followed by skin grafting routinely. Method B was used in patients who would be treated with intramedullary Kirschner wire fixation after release of scar contracture and skin transplantation routinely. Method C was further used in patients when methods A and B failed to accomplish the expected result. Method C was used in the first place followed by method A in whom there might be vascular decompensation or exposure of tendon and bone after scar release, and those who failed to meet the expectation were treated with method C in addition. Patients who were unwilling to undergo surgery were treated with method C exclusively. During the course of treatment, the presence or absence of infection and slipping of Kirschner wire or its slitting through soft tissue were observed. The presence or absence of tendency of recurrence of scar contracture within 1 to 2 weeks after treatment was observed. The length of palmar skin measuring from the root of finger with contracture to wrist crease was measured before treatment, at the termination of treatment, and 1 month after the termination of treatment. Scar condition was assessed with the Vancouver Scar Scale (VSS) before treatment and 1, 3, and 6 month(s) after the termination of treatment. Before treatment and 1 month after the termination of treatment, the range of motion was measured with the Total Active Movement (TAM) method; band function was evaluated by the Jebsen Test of Hand Function (JTHF), and the completion time was recorded. Data were processed with analysis of variance, LSD-t test, and t test.

RESULTSTwenty-four patients with 27 affected hands were treated with scheme A + B; 5 patients with 7 affected hands were treated with method C exclusively; 2 patients with 3 affected hands were treated with scheme A + B + C; 1 patient with 2 affected hands were treated with scheme C + A + C. During the course of treatment, no complication such as infection or slicing of tissue was observed, but there was a slight shifting of U-shaped Kirschner wire in 14 affected hands of 13 patients. Tendency of recurrence of scar contracture was observed in 11 affected hands of 10 patients, but the scar contracture did not reoccur after treatment with orthosis. The skin length of palmar side was respectively (131.8 ± 9.8) and (127.6 ± 7.5) mm at the termination of treatment and 1 month after, and they were both significantly longer than that before treatment [(114.5 ± 2.4) mm, with values respectively 10.71 and 10.39, P values below 0.001]. The score of VSS was respectively (9.8 ± 2.4), (9.7 ± 1.7), (9.3 ± 0.8), and (7.7 ± 0.5) points before treatment and 1, 3, and 6 month(s) after the termination of treatment. Only the score at 6 months after the termination of treatment was significantly lower than that before treatment (t = 3.28, P < 0.01). The ratio of excellent and good results according to method TAM was respectively 2.6% (1/39) and 94.9% (37/39) before treatment and 1 month after the termination of treatment. The time for JTHF measurement was (13.9 ± 4.1) min before treatment, and it was shortened to (11.0 ± 2.8) min 1 month after the termination of treatment (t = 3.65, P < 0.001).

CONCLUSIONSSingle application of metacarpus and phalanx traction or its combination with skin transplantation after scar release in correcting scar contracture of the palm of hand after burn can lengthen the contracted tissue, and it is beneficial for the restoration of function and appearance of affected hand.

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 observe the influence of chitosan on the skin and soft tissue expansion.Methods Twenty-five patients were selected,who were suitable to be embedded soft tissue expanders in the face,a 100-milliliter expander was implanted in one side of the face,and other side was used as control.A 100-milliliter expander was implanted in each group,and a slender silicon duct was embedded between the expander and subcutaneous tissue in the experimental group.About five to seven days after the operation,the negative drainage tube was removed,and then two-milliliter medical chitosan injected with the silicon duct in the experimental group,but not in the control group.Two groups were injected with normal saline in the second day.The center of expanded skin was pressed and skin elasticity and relaxation were compared between the two groups during the injection interval.The time of injection interval,the quantity of normal saline inside the expanders after two weeks and three weeks and the total time of expansion to 100 milliliters were recorded.After injection was completed in the two groups and maintained for two weeks.In the stage Ⅱ operation,the expanders were taken out,1 cm × 1 cm fibropeplos was removed from the center of the expanded skin flap from the two groups,and pathological section was prepared to measure the thickness of fibropeplos,average gray scale of collagen and the quantity of blood capillaries.The fibroblasts,collagen fiber and capillaries were observed and compared under light microscope.A matched-pairs t analysis was used to analyze the data.Results Compared with the control group,the quantity of normal saline inside the expanders in the experimental group was increased at the same time; the water injection period was shorten and tissue expansion was significantly accelerated.The number of fibroblasts in the fibropeplos decreased with the influence of chitosan.The fibroblasts were restrained to mature period and collegan decreased.The fibropeplos became thinner but the capillaries were not affected.Conclusions Chitoson can inhibit fibroblast proliferation and collagen production,and the effect of accelerating tissue expansion is significant and deserves to be recommended.

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.
