Objective To design and develop a reliable,ease-to-use and cheap tissue microarryer for making tissue microarrays,and discuss its characteristics.Methods According to the facture procedure and principle of tissue microarray construction,HT-1 tissue microarrayer was designed and developed.The tissue microarrayer consisted of a recipient paraffin block molding machine,a punch needle,a negative-pressure embedding instrument,and a special manipulator.Using HT-1 tissue microarrayer,the array holes in recipient paraffin block could be punched by single-shaping technique in one action in several seconds,while no chapping was guaranteed.During the TMAs paraffin block embedding process,the remnant air bubble between the tissue cylinders and array holes in recipient paraffin block could be exhausted rapidly and completely.Results Using HT-1 tissue microarrayer,an array holes recipient paraffin block(several to several hundreds holes)could be made in several seconds.Several TMAs blocks with 56 tissue cylinders(1.5 mm in diameter)were constructed easily and quickly within 20 min.Under HE and immunostaining procedures,the tissue cores were well aligned,and orientation was properly done.The tissue cores on the slide maintained intact histological structure.The tissue structure and background of the HE and immunostaining were clear.There was less sample loss(the loss rate was less than 1.0%?1.1%).Conclusion HT-1 tissue microarrayer is a simple,economical and high efficiency/cost(E/C)and easy-to-use device.

Objective To investigate whether area under the curve (AUC) of oral glucose tolerance test (OGTT) could work as a predictor of outcomes of gestational diabetes mellitus (GDM) on condition that blood glucose is controlled. Methods A total of 1 796 women who had a standard antenatal care in Peking University First Hospital and gave single live births from July 1, 2011 to December 31,2 013 were included.They should be diagnosed of GDM by the diagnosis criteria of gestational diabetes published by the Ministry of Health of PRC and diabetes pre-pregnancy excluded. Data were analyzed with SPSS 17.0, grouping by AUC. Results (1)Women with higher AUC had a rising trend of age and a downward trend of gestational weight gain, however, not statistically significant [specifically, in the four group of less than 15.00 mmol·L-1·h-1, 15.00 to 16.79 mmol · L-1 · h-1, 16.80 to 17.99 mmol · L-1 · h-1 and 18.00 mmol · L-1 · h-1 or more, gestational weight gain was (15.3±5.2), (14.1±4.8), (13.5±4.7) and (13.1±4.8) kg]. The prevalence of macrosomia raised while AUC increased. Those with an AUC of lower than 15.00 (mmol·L-1·h-1) had a lower risk of macrosomia (P=0.04) . But those with an AUC of 18.00 (mmol·L-1·h-1) or more had a higher risk of macrosomia (P=0.02). There was a rising trend in premature birth and preeclampsia with AUC increasing but not significant (the prevalence of premature birth was 4.38%, 5.36%, 7.71%and 7.94%while that of preeclampsia was 2.85%, 4.69%, 4.67% and 5.08% in these four groups).(2)The prevalence of macrosomia was 12.76% (54/423) when overweight pre-pregnancy ,significantly higher compared with 5.87%(65/1 107) in normal group. The prevalence of preeclampsia was 5.91%(25/423) and 3.34%(37/1 107) in those two groups, which was also significantly different. The obese group had a statistically highest prevalence of preeclampsia of 9.23%(12/130). (3)AUC (P<0.05, OR=1.113, 95%CI:1.008-1.218), as well as gestational weight gain (P<0.05, OR=1.520, 95%CI:1.279-1.806) and pre-pregnancy BMI (P<0.05, OR=1.183, 95%CI:1.125-1.243) made a difference in the prevalence of macrosomia. Meanwhile, pre-pregnancy BMI made sense in the prevalence of premature labor (P<0.05, OR=1.059, 95%CI:1.003-1.119) and preeclampsia (P<0.01, OR=1.202, 95%CI:1.123-1.286). Conclusions AUC, as well as pre-pregnancy BMI and gestational weight gain have a significant impact on outcomes of GDM, macrosomia especially, though blood glucose is controlled. Meanwhile, AUC might be considered as a predictor of macrosomia.

Objective To assess the reflectance confocal microscopic features of childhood lichen planus (LP),and to evaluate the performance of reflectance confocal microscopy (RCM) in the diagnosis of childhood LP.Methods RCM was performed for imaging of lesions in 35 children with LP.Then,biopsies were carried out at the same sites followed by histopathological examination.A comparison was conducted between confocal microscopic and histopathological findings.All the 35 cases were diagnosed based on clinical manifestations and histopathological findings.Results RCM imaging of lesions in the 35 cases showed cellular edema forming lowly reflective areas in the epidermis,sharp transition between the granular and spinous layers,and infiltration of moderately reflective inflammatory cells,which corresponded to wedge-shaped thickening of the granular layer on pathological examination.The dermo-epidermal junction was unclear,and dermal papillary rings were obscure or absent with infiltration of inflammatory cells arranged in lamelliform structures around the dermo-epidermal junction,which corresponded to interface dermatitis on histopathological examination.A band-like infiltration of inflammatory cells,including big,highly reflective oval or stelliform pigmentophages and small,moderately reflective round lymphocytes,was observed in the dermis,and the thickness of infiltration was measurable.Dilated blood vessels were longitudinally distributed in the papillary dermis with perivascular infiltration of inflammatory cells and pigmentophages.RCM images were highly consistent with histopathological findings in these patients.Conclusion RCM,as a real-time non-invasive imaging technique,can serve as an auxiliary examination method for the diagnosis of childhood LP.

Objective To evaluate the results of one-day care for gestational diabetes mellitus (GDM) and pregnancy outcome after application of new diagnostic criteria.Methods We retrospectively analyzed the clinical features of a GDM group (n=841) and a normal glucose metabolism group (n=3 043) who delivered in Department of Obstetrics and Gynecology,Peking University First Hospital between July 1,2011 and June 30,2012,to discuss the difference in maternal and newborn outcomes between these two groups,and to compare the maternal and newborn outcomes between the GDM one-day care group (study group,n=605) and non-GDM one-day care group (control group,n=236).Statistical analysis was performed by t test and x2 test.Results The average age of pregnant women with GDM was (31.5±4.2) years,which was higher than the normal glucose metabolism group (30.0±3.7) years (t=9.13,P＜0.01).The average age of the study group was (31.7±4.2) years,and the average age of the control group was (31.7±4.9) years,which was not a significant difference (t=2.32,P＞0.05).In the oral glucose tolerance test,fasting blood glucose level was (5.2±0.5) mmol/L,which was significantly lower than that in the control group (5.3±0.8) mmol/L (t=2.48,P＜0.05).The difference between 1 and 2 h glucose sugar levels did not differ significantly (P＞0.05) between the two groups.In the GDM and normal glucose metabolism groups of pregnant women,the incidence of macrosomia was 6.5％ (55/841) and 5.9％ (182/3 043),respectively,although the difference was not significant (x2=0.36,P＞0.05).In the GDM group,the rate of premature delivery was significantly higher than in the normal glucose metabolism group [preterm birth:10.1％ (83/841) and 7.4％ (225/3 043),x2=5.56; P＜0.05)].In the GDM group,gestational hypertension and mild pre-eclampsia were significantly more frequent than in the normal glucose metabolism group [gestational hypertension:4.2％ (35/841) vs 2.6％ (82/3 043),x2=4.85; mild pre-eclampsia:1.7％ (14/841) vs 0.9％ (26/3 043),x2=4.24; P＜0.05].The incidence of severe pre-eclampsia was 2.4％ (20/841) and 1.6％ (49/3 043),respectively,which was not significantly different (x2=2.22,P＞0.05) between the two groups.The rate of insulin use was 9.3％ (78/841) in the GDM group.In the study group,the rate of insulin use was 7.9％ (48/605),compared with 11.9％ (28/236) in the control group; this difference was not significant (x2=3.54,P＞0.05).In the study group,the incidence of macrosomia and hypertensive disorder complicating pregnancy (HDP) was similar to that in the control group [macrosomia:6.9％ (42/605) vs 5.3％ (13/236),respectively; x2=0.57; HDP:7.4％ (45/605) vs 9.9％ (24/236),x2=1.68; P＜0.05].The rate of premature delivery in the study group was significantly lower than in the control group [7.2％ (44/605) vs 16.0％ (38/236),x2=15.04,P＜0.05].In the study group,among the 561 cases of term birth,there were 42 cases of macrosomia.The average age of macrosomic and non-macrosomic pregnant women [(31.4±3.9) vs (31.7±4.2) years,t=4.27],pre-pregnancy body mass index [(23.5±3.9) vs (22.6±3.2),t=1.58],gestational weight gain [(16.1±5.6) vs (15.7± 11.4) kg,t=0.22] and pregnant weeks at visit to a one-day care clinic [(27.5 ± 4.3) vs (28.1 ± 2.8) weeks,t=0.86; P＞0.05] showed no significant differences.In women who delivered an infant with macrosomia,glycosylated hemoglobin levels in mid and late pregnancy were higher than in woman who did not deliver an infant with macrosomia [(5.6±0.4) ％ vs (5.4±0.4) ％,t=2.13,P＜0.05].Conclusions Through one-day care for GDM,the rate of preterm labor is reduced.This is a good model for group management of GDM women,and more efforts is required to improve its effect.

Objective To emphasize the importance of embolization of nonbronchial systemic arteries in treatment of acute and life-threatening massive hemoptysis.Methods In a series of 146 patients with hemoptysis who underwent bronchial artery embolization,we found 12 cases whose blood supply were from 17 nonbronchial systemic arteries and hemoptysis was more than 300 ml blood within 24 hours.Embolic materials included absorbable gelatin sponge(GS),kelp micro gelatin(KMG),polyvinyl alcohol(PVA) particles and metal coils. Results In the 12 cases with 17 nonbronchial systemic arteries (4 were intercostal,3 internal mammary,3 thyrocervical trunk,3 inferior phrenic,1 left gastric,2 originated from the inferior aortic arch,and 1 originated from anterior abdominal aortic wall).Five cases were embolized by GS alone,2 cases by KMG,3 cases by GS+PVA,and 2 cases by GS+PVA+metal coils.Eight cases were performed embolization once,3 cases were performed twice and 1 case was performed three times.No significant complications developed related to embolization,except that 1 patient had transient eyesight decrease after embolization of thyrocervical trunk and 2 patients had chest pain after embolization of intercostal artery which resovled without any treatment.Conclusions During bronchial artery embolization for hemoptysis patients,all supplying artery should be searched and found.Even after successful embolization of bronchial arterys for hemoptysis patients,nonbronchial systemic arterial supply should still be taken into account.

Objective To explore main technical points and clinical efficacy of individualized stepwise multiple embolization treatment for refractory hemoptysis. Methods To retrospectively analyze materials of 103 patients treated by individualized stepwise multiple embolization. According to disease categories, individualized stepwise multiple embolization treatment with polyvinyl alcohol and loaded sodium alginate microspheres as basic embolization agent were performed, after the type, number, abnormal branches, pulmonary circulation and systematic pulmonary shunt of targeted vessels were confirmed through radiography. To judge short(less than 3 months), medium(3 to 6 months) and long term(more than 6 months) efficacy, resolution of hemoptysis after operation were assessed. To evaluate efficacy of individualized stepwise multiple embolization treatment for refractory hemoptysis, Kaplan-Meier survival curves were used. According to the features of target vessels to supply blood, patients were classified into with SPS and without SPS. By using Log-Rank test, the effective rates of one-year were compared between them. Results Out of 103 patients, 215 target vessels were demonstrated, among which individualized stepwise multiple embolization was for 196 target vessels, peripheral embolization for 8 vessels, and main trunk embolization in 11 patients. The visits after operation were made to 103 patients after 6 to 50 months, with the medium of 21 months. Hemoptysis was instantly resolved in 97.1%(100/103). The effective rates were 94.5%,93.2%, 89.7%,88.9%,85.2%and 76.6%for one, three, six months and one, two and three years after operation. In 103 patients, patients with SPS were 22 and without SPS were 81. One-year effective rates with and without SPS were (69.50 ± 0.11)% and (98.30 ± 0.03)% , respectively (χ2=11.662,P<0.01). Conclusion Individualized stepwise multiple embolization treatment shows excellent short-term and mid-long term efficacy in the treatment of refractory hemoptysis.

OBJECTIVETo reconstruct a simpler and reliable composite tissue transplantation model-the femur osteomyocutaneous flap for the replacement of hindlimb transplantation.

METHODSTen femur osteomyocutaneous flaps from 5 Lewis rats were transplanted into 10 syngeneic recipients' inguinal region. Their nutrient vessels were anastomosed with recipients vessels. The graft of this model was consisted of the groin flap and partial femur. To verify the feasibility of this model, gross and histological appearance were studied after transplantation to evaluate the viability of grafts.

RESULTSThe operative time was (159.0 +/- 8.3) min with the harvesting time of (68.0 +/- 4.8) min and the ischemia time of (55. 8 +/- 6.8) min. The methylene blue injection showed rich blood supply of transplanted femur osteomyocutaneous flap. All the 10 flaps survived completely with pink skin color and hair regrowth. The histologic examination of the flaps also revealed the normal appearance of the viable skin and bone marrow.

CONCLUSIONSThe femur osteomyocutaneous flap is a simple and reliable model for composite tissue transplantation, and its establishment will provide a new tool for the study of composite tissue allografts.
