Objective To investigate the laboratory ifndings, clinical manifestations and treatment in hemolytic disease caused by red cell immune antibodies in neonates. Methods The laboratory and clinical data from 4 cases of hemolytic disease of neonates caused by red cell immune antibodies were retrospectively analyzed. Results IgG antibody were detected in all mothers of 4 cases during pregnancy and they were anti-E, anti-D, anti-Jkb and the autoantibody with the titer being 16, 2048, 1 and 16 respectively. The four neonates were all full-term. The jaundice appeared 6 h to 3 d after birth with varying degrees of skin stained yellow, with or without anemia. Serology and elution test found the existence of antibody same as the one on their maternal red cells and the titer was 4, 512, 0, and 2, respectively. All neonates were treated by phototherapy. Two servere cases were also treated by whole blood exchange and red blood cells transfusion. The prognosis were good in all neonates. Conclusions Prenatal immune hematological tests facilitated early detection of irregular erythrocyte antibodies and thus assessment of the risk of hemolytic dis-ease of the fetus and neonates.

Objective To evaluate the results of prosthesis augmentation,relieve suffering patient experience,improve shape and touch of breast.Methods According to design,in dual-plane mammaplasty transaxillary approach with endoscopic assistance,we used soft-tissue expansion before prosthesis,saline volume in expander was the same as prosthesis size at beginning; adjusting expander volume and position,then determined prosthesis size according to expander volume lastly.after intraoperative sustained expansion for 30 to 60 minutes twice prosthes volume,replace expander with prosthesis.Results This method was applied in 120 patients,showing that pain significantly reduced after expansive without use of analgesia pump; complications included that 3 patients appeared seroma and absorbed soon; 2 patients had poor prosthese location,which was adjusted in reoperation; one capsular contracture was repaired later.After 6-months to 2-years follow-up,the results showed that breast was nature and dynamic; satisfactory rate reached to 95 ％.Conclusions In augmentation mammaplastic operation,pre-adoption of an expander can make it easy to adjust the location of prosthesis,to avoid being injured and to determine prosthesis volume by expander injection of saline volume,especially for patient with different size of both breasts.

Objective To study the effect of dexmedetomidine and midazolam on hemodynamics and sedation in patients with nasal intubation.Methods Forty patients whose ASA grade Ⅰ-Ⅱ and anticipated difficult airway were randomly divided into dexmedetomidine group(group D,20 cases)and midazolam group(group M,20 cases)according to the admission number.In group D,dexmedetomidine 1 μ g/kg were constant speed pumped in 10 minutes.In group M,midazolam 0.03 mg/kg were intravenous injected.Then nasal intubation were carried.Systolic blood pressure(SBP),diastolic blood pressure(DBP),mean arterial blood pressure(MAP),heart rate(HR),pulse oxygen saturation(SpO2),Ramsay sedation score,rate-pressure product(RPP),tip perfusion index(TPI)were recorded and compared before anesthesia (T0),fiberoptic bronchoscope pass by later nostril(T1),to spy on epiglottis(T2),intubation succeed(T3),after intubation 1 minute(T4)and after intubation 3 minutes(T5).Airway score and postoperative visit were evaluated.Results SBP,DBP,MAP,HR,RPP in group M were significantly higher at T1-T3 than those at T0 (P＜0.05),and were significantly higher than those in group D at the same time(P＜ 0.05).There was no significant difference in group D(P ＞ 0.05).Ramsay sedation score and TPI at T1-T3 in group M were significantly lower than those at To(P ＜0.05).Ramsay sedation score and TPI at T1-T5 in group D were significantly higher than those at T0(P ＜ 0.05),and were significantly higher than those in group M at the same time(P ＜ 0.05).The rate of airway score 1 score and intubation satisfaction in group D were significantly higher than those in group M[100％(20/20)vs.30％(6/20),90％(18/20)vs.50％(10/20)](P＜ 0.05).The rate of throat ache in group D was significantly lower than that in group M[5％(1/20)vs.35％(7/20)](P ＜0.05).Conclusions For difficult airway patients with nasal intubation during dexmedetomidine infusion,hemodynamics is stable and sedation is satisfied.

AIM: To observe effects of shear stress and TNF-? on caveolin-1 expression. METHODS: Cultured human aortic endothelial cells (HAECs) of passage 3-5 were used in the experiment. Cells were exposed to a laminar flow (shear stress 1.0 Pa) by using a parallel rectangular flow chamber for different time. Caveolin-1 mRNA and protein expression were measured by RT-PCR and Western blot, respectively. Caveolin-1 expression of the cells stimulated by TNF-? were also studied to elucidate the influence of this inflammatory factor. RESULTS: After 24 h of exposure to 1.0 Pa shear stress, both of caveolin-1 protein and mRNA expression decreased in HAECs, especially caveolin-1 mRNA expression (P

A questionnaire was used to survey the perspective of the 22 mentors,24 students, 27 graduate students and 27 public health units on the competence of MPH student. The result showed that the practice skill,analyzing skill,program plan and practice skill,and emergency reaction abil-ity got more attention. This suggested that to the training of MPH,the training objective should focus on the ability to resolve problems; the curriculum should focus on the characters of public health and on the practice training.

OBJECTIVETo investigate the clinical characteristics of Segond fracture combined with injuries, and to explore the operative method and opportunity.

METHODSFrom June 2010 to December 2014, 10 patients with Segond fracture were treated. There were 10 males, ranging in age from 26 to 69 years old, with a mean of 42 years old. Under arthroscopy examination within 7 to 10 days after injury, 6 patients had compete rupture of anterior cruciate ligament and meniscus injury; 2 patients had tibial avulsion fractures of the ACL combined with meniscus injury. At 4 to 8 weeks after injury, 2 patients were performed with arthroscopy examination; 1 patient had complete rupture of anterior and posterior cruciate ligament combined with meniscus injury; and the other patient had complete rupture of anterior cruciate ligament alone. All the patients with cruciate ligament rupture were treated with reconstruction of cruciate ligament; 9 patients had meniscus injuries were treated with menisus plasty or suture; and 2 patients had tibial avulsion fractures of the ACL were treated with non-absorbable Ethicon suture fixation under arthroscopy. After operation, the Lysholm scoring system was used to evaluate clinical effects.

RESULTSEight patients were operated within 10 days after injury, the knee joints swelling was obvious at the 3rd day after operation, and blood oozing was found by joint puncture. These 8 patients did out-of-bed activity with assistance at 1 week postoperatively. Other 2 patients performed operation in 4 to 8 weeks after injury without knee joint obvious swelling at the 3rd day after operation, and no blood oozing was found by joint puncture. These 2 patients did out-of-bed activity with assistance after 3 days postoperatively. All the patients were followed up, and the duration ranged from 12 to 24 months, with an average of 18 months. Postoperative Lysholm score of all patients was higher than preoperative scor, and the results were satisfactory.

CONCLUSIONFor Segond fractures, firstly, it is important to gain early diagnosis for treatment. Secondly, it is often associated with the rupture of anterior cruciate ligament and meniscus injuries, and the best time of cruciate ligament rebuilding and meniscus repairing maybe between 4 to 8 weeks after injury. Thirdly, personalized treatment should be chosen according to different complications.

OBJECTIVETo explore the correlation of the gene polymorphisms of Toll-like receptor 2 ( TLR2) and TLR4 with the susceptibility and recurrence of condyloma acuminatum (CA).

METHODSUsing Snapshot, we detected the gene polymorphisms of TLR2 597(T/C), 1350(T/C), 15607(A/G), and 2258(G/A) and TLR4 896(A/G) and 1196(C/T) in the peripheral blood of 140 CA patients and 105 HPV-negative controls. We made comparisons between the CA patients and controls as well as between the cases of recurrent CA and those of non-recurrence at 6 months after treatment.

RESULTSThere were 72, 48, and 20 cases of genotype TT, TC, and CC of TLR2 597 (T/C), respectively, in the CA patients, as compared with 71, 31, and 3 cases in the controls. The gene frequency of mutant C was 31. 43% in the patients, significantly higher than 17.62% in the controls (χ2 = 12.04, P < 0.01), and it was 38.68% in the recurrent cases, remarkably higher than 27.01% in the non-recurrent cases (χ2 = 4.16, P < 0.05). There were 74, 49, and 17 cases of genotype TT, TC, and CC of TLR2 1350( T/C), respectively, in the CA patients, as compared with 73, 29, and 3 cases in the controls. The gene frequency of mutant C was 29. 64% in the patients, significantly higher than 16. 67% in the controls (χ2 =11.05, P < 0.01), and it was 36.79% in the recurrent cases, markedly higher than 25. 29% in the non-recurrent cases (χ2 = 4.18, P < 0.05). There were 44, 66, and 30 cases of genotype AA, AG, and GG of TLR2 15607(A/G), respectively, in the CA patients, as compared with 26, 58, and 21 cases in the controls. There was no significant difference in the gene frequencies of mutant G between the two groups (χ2 = 0.33, P > 0.05). No mutant genes of TLR2 2508 (G/A) or TLR4 896(A/G) and 1196(C/ T) were detected in either the CA patients or the controls. Linkage disequilibrium analysis showed a tight linkage between TLR2 597 (T/C) and 1350(T/C) (D' = 1, r2 = 0.93).

CONCLUSIONTLR2 597(T/C) is tightly linked to 1350(T/C), which is correlated with both the susceptibility and the recurrence of condyloma acuminatum.
