Objective:To determine the relationship between trimester-specific gestational weight gain and pregnancy outcome among women with twin pregnancies.Methods:A retrospective cohort study was conducted among Chinese women with twin pregnancies delivered from January 2013 to October 2015 in the International Peace Maternity & Child Health Hospital of China Welfare Institute.Gestational weight gain was compared between women with different progestational BMI.After the adjustment for age and progestational BMI,binary Logistic regression analysis was conducted to explore the relationship between gestational weight gain rate and gestational complications,premature birth,premature rupture of membrane and neonatal birth weight.Results:①A total of 472 subjects met the inclusion criteria.Rate of gestational weight gain were(0.41 ±0.15),(0.64 ±0.30) and (0.49 ±0.15) kg/week in Early,Mid-and Late-,and Whole of pregnancy respectively.②With regards to trimester-specific gestational weight gain,statistically significant associations were found between rate of weight gain and gestational hypertension and preterm birth (P ＜ 0.05).Those with faster gestational weight gain had higher rate of premature rupture of fetal membrane(P ＜ 0.05).And those with lower gestational weight gain had lower neonatal birth weight(P＜0.05).③After adjusting maternal age,progestational BMI and gestational age at delivery,the sum of twins' birth weight increased 25.21g,30.89g and 21.46g respectively when the maternal body weight increased 1kg during the whole pregnancy,in Early and Mid-pregnancy (P ＜ 0.001),and during in Late-pregnancy(P =0.001).Conclusions:Gestational weight gain among women with twin pregnancy are closely related with adverse pregnancy outcomes.The gestational weight gain rate in different gestation are of some predictive value for pregnancy outcomes.More research with long follow-up are needed to determine proper gestational weight gain for twin pregnancy suitable for Chinese women.

Objective:This study investigates the clinical effect of bodyγ-knife combined with radiosensitizer and/or hyperthermia. for the recurrence of soft tissue sarcoma. Methods:Sixty-three patients with recurrent soft tissue sarcoma from January 2012 to March 2014 were treated by bodyγ-knife combined with radiosensitizer and/or hyperthermia. The patients were exposed to radiation dose levels of 4-5.5 Gy/fraction (10-13 fractions) with total doses of 44-55 Gy and 55%-70%isodose, including 95%PTV. The radiosensitizer, sodium glycodidazolum (CMNa), was administered to all patients at 1.00-1.50 g V.D qod at 5-6 fractions 0-3 h before bodyγ-knife treat-ment. Hyperthermia for 30 patients was delivered during the bodyγ-knife treatment with two fractions/week for a total of six frac-tions. Results:The total response rate was 77.7%three months after the treatment. The one and two year local control rates were 78.8%and 63.6%, respectively, while the survival rates of patients treated with bodyγ-knife with radiosensitizer at one and two years were 75.7%and 63.6%, respectively. The local control rates at one and two years were 83.6%and 70.0%, respectively, while the surviv-al rates at one and two years for bodyγ-knife combined with radiosensitizer and hyperthermia treatments were 80.0%and 63.3%, re-spectively. Serious complications of radiotherapy were not observed. Conclusion:Bodyγ-knife combined with radiosensitizer and/or hyperthermia is effective for recurrent soft tissue sarcoma.

Objective To summarize the clinical data of 45 cases of familial adenomatous polyposis(FAP) and the experiences of treatment and diagnosis of FAP. Methods Retrospectively analyzed of the clinical data was made on 45 FAP patients.The choice of operative procedure included total colectomy+ileostomy in 25 cases,subtotal colectomy+rectal polyposis electrocautery in 15,and total colectomy with ileo-anal anastomosis in 5. Results Average age of patients at first diagnosis was 33.5 years. A family history was found in 35 patients. Bleeding, diarrhea, pain are common clinical presentations, and the numbers of polyposis were all more than 100. All patients without malignant change survived for 3-21years;and metastasis of liver was the main cause of death in patients with malignant change. There were age differences between malignant and non malignant group. Conclusions FAP lacks typical clinical presentation, and misdiagnosis is not uncommon. Surgical therapy should be done on an individual basis and according to the actual condition of patients.

Objective:To investigate the efficacy of stereotactic body radiation therapy with gamma-knife (γ-SBRT) combined with targeted drug sorafenib and hyperthermia for the treatment of recurrent and metastatic hepatocellular carcinoma. Methods:A total of 71 patients with recurrent and metastatic hepatocellular carcinoma were admitted from August 2007 to December 2009. Among these patients, 39 were treated with γ-SBRT and hyperthermia (group 1); 19 were treated with γ-SBRT combined with sorafenib and hyperthermia (group 2). Results: The total efficacy rate after a three-month treatment was 83.1% (59/71). In group 1, the following results were obtained:one-and three-year local control rates of 41.0%(16/39) and 18%(7/39), respectively;one-and three-year overall survival (OS) rates of 41.2% and 17.9%, respectively; and one- and three-year progression-free survival (PFS) rates of 38.4% and 15.4%, respectively. In group 2, the following results were obtained:one-and three-year local rates of 56.3%(18/32) and 28.1%(9/32), respectively;one-and three-year OS rates of 62.5%and 28.1%, respectively;and one-and three-year PFS rates of 59.4%and 25.0%, respectively. Significant differences in OS and PFS were observed between the two groups. Conclusion:The combination ofγ-SBRT with targeted drug sorafenib and hyperthermia can be used effectively to treat recurrent and metastatic hepatocellular carcinoma. Adverse reactions are mild, and patients can tolerate this treatment.

Objective To evaluate the efficacy of different treatment regimens for children with acute promye-locytic leukemia (APL)with positive PML -RARa fusion gene.Methods Thirty -two newly diagnosed APL patients were included in this study,treated either with all -trans -retinoic acid (ATRA)and chemotherapy (CT)(group A) or with ATRA and arsenic trioxide (ATO)(group B).Clinical situation and clinical efficacy were analyzed in patients in different groups.They were also separated into low risk group,intermediate risk group and high risk group according to different risk criteria.Clinical characteristics,complete remission,long -time survival and urine arsenic concentra-tion were analyzed and compared.Results (1 )Fourteen of 1 5 patients (93.3%)in group A achieved hematological complete remission (HCR)with a median time of 38 days (28 -63 days).Sixteen of 1 7 patients (94.1 %)in group B achieved HCR with a median time of 29 days (1 0 -42 days),which was significantly shorter than group A,and there was a significant difference between 2 groups(t =3.53,P =0.002).(2)The 5 -year event -free survival (EFS)of group A and group B was (60.0 ±1 2.6)% and (81 .9 ±9.5)%,respectively;the 5 -year EFS of group B was almost 20% higher than group A;while there was no significant difference between the 2 groups(χ2 =1 .1 5,P =0.28).The 5 -year overall survival (OS)of group A and group B was (72.2 ±1 1 .9)% and (94.1 ±5.7)%,respectively,the 5 -year OS of group B was almost 20% higher than group A;while there was no significant difference between the 2 groups(χ2 =2.88,P =0.1 6).(3)The 5 -year EFS of low plus intermediate group and high risk group patients was (74.0 ±1 0.1 )% and (64.8 ±1 4.3)%,the 5 -year EFS of low plus intermediate group was almost 1 0% higher than high risk group,but there was no significant difference between the 2 groups(χ2 =0.1 4,P =0.71 ).The 5 -year OS of low plus intermediate group and high risk group patients was (84.7 ±8.1 )% and (71 .3 ±1 4.1 )%,the 5 -year OS of low plus intermediate group was almost 1 0% higher than high risk group,while there was no significant difference be-tween the 2 groups(χ2 =0.36,P =0.55).(4)ATO related side effects were mild,including abnormal liver tests and e-lectrocardiogram,but were invertible after supportive therapy.At the end of each chemotherapy course,the urine arsenic concentration remained low and no chronic arsenic toxicity or second malignancies were found during the follow -up period.Conclusions The ATRA plus ATO regimen is a promising and better treatment for childhood APL with positive PML -RARa fusion gene compared with conventional chemotherapy.It was necessary to take risk stratification in APL patients.

Objective To discuss the effects of repairing nasal ala defects by free transplantation of autogenous auricle composite tissue flap. Methods 50 cases with nasal ala defects were repaired by free auricular composite tissue flap transplantation from Janu 2003 to May 2013. The defects size was 0.5cm x 0.7cm~1.3cm x 1.5cm. According to the size of the defects, full thick wedge-shaped auricle composite tissue flap were cut off, then inserted into the nasal ala defects area and fixed stablely, the donor sites were sutured directly avoiding ear cartilage. Salvianolate and hyperbaric oxygen were used in postoperative treatment for 5-7 days. Results 48 cases achieved good results, 2 cases had partial necrosis of composite tissue flap after operation, also achieved good results after reoperation. Over 3 months~5 years follow-up, all cases had satisfactory results. The volume of auricle composite tissue flap reduced less than 10%. Surgical incisions had a linear scar, good color matching, nostril symmetry. All patients were satisfied with the overall appearance. Conclusions Autogenous auricle composite tissue flap free transplantation for repairing middle and small size of nasal ala defects can recover ala formation and structure very well, nasal appearance can be improved greatly with nostril symmetry. There is no hypertrophic scar in donor sites. This method is simple and easy,and is also a good method for repairing nasal ala defects.
