Objective To investigates factors affecting the positive rate of blocking antibody treated by paternal lymphocyte immunotherapy in patients with recurrent spontaneous abortion (RSA).Methods From January 2008 to August 2012,326 RSA cases undergoing treatment in Infertility Center of Qilu Hospital were studied retrospectively.Those patients were divided into 2 groups randomly:260 cases in intradermal injection group were administered via bilateral forearm intradermal injections for immunotherapy once 21 days,then the blocking antibody was determined after 2 (23 cases),3 (73 cases),4 (74 cases),5(90 cases) times respectively,while in subcutaneous injection group,the 66 cases were administered via subcutaneous injection once 21 days,the blocking antibody measured after 3 times; In both cases,the blocking antibody was all determined 2 weeks later.The positive rate of blocking antibodies and the rate of successful pregnancy was recorded,and then followed up after the blocking antibody turning positive.Results (1)Positive rate of blocking antibodies:the positive rate of blocking antibodies were 17％ (4/23),58％ (42/73),72％ (53/74) and 84％ (76/90) in the 2,3,4,and 5 times of intradermal injection group,respectively (P ＜ 0.05).In subcutaneous injection group,the positive rate of blocking antibodies was 38 ％ (25/66),which was significantly lower than that in group intradermal injection receiving 3 times immunotherapy (P ＜0.05).(2) The rate of pregnancy:the 176 patients out of 200 patients were pregnant when antibody was positive after immunotherapy,with 71.6％ (126/176)of patients gained successful pregnancy(the length of pregnancy more than 5 months).Conclusions The route and frequency of administration of immunotherapy could influence the positive rate of blocking antibody.The rate of successful pregnancy will be increased after blocking antibody turning positive.

Objective To investigate the result and side effect of late course accelerated three-di-mensional conformal radiotherapy (3DCRT) for esophageal carcinoma. Methods From July 2003 to March 2006, 55 patients with esophageal carcinoma receiving 3DCRT were randomly divided into late course accel-erated radiation group (group A, 27 patients) and conventional fractionation group (group B, 28 patients). The prescribed dose in group B was 64 -66 Gy, 2 Gy per fraction, 1 fraction per day, 5 fractions per week for about 6.5 weeks. Patients in group A received conventional fractionation irradiation for the first 4 weeks. Then the dose was increased to 3 Gy per fraction to a total dose of 67 -70 Gy. The treatment course in group A was about 6 weeks. The treatment response, acute site effects, 1-, 3-and 5-year local control rates and o-verall survival rates of the two groups were observed. Results In group A, 23 patients (85%) achievedcomplete response (CR) and 4(15%) achieved partial response (PR). While in group B, 16 patients (57%) achieved CR and 12(43%) achieved PR. The CR rate was significant higher in group A (χ~2 = 5.24,P=0.022). The 1-, 3-, 5-year local control rates were 85%, 54%, 54% in group A, and 70%, 56%, 33 % in group B (χ~2 = 0.68, P = 0.409), respectively. The 1 -,3-,5-year overall survival rates of the two groups were 81%, 37%, 29% and 61%, 39%, 23% (χ~2 = 0.06, P = O. 804), respectively. Both lo-cal control and overall survival were similar between the two groups. The incidences of acute radiation esoph-agitis in the two groups were similar (85% vs. 89% ;χ~2 =0. 00,P=0. 959), and the incidence of radiation pneumonitis was slightly higher in group A than in group B (67% vs 43% ;χ~2 =3.14,P =0.076). By the last follow up, 19 patients in group A and 21 in group B died. Among them, 10 in group A and 15 in group B died of local failure, while 7 in group A and 5 in group B died of metastasis. Conclusions When com-pared with conventional fractionation 3DCRT, late course accelerated 3DCRT for esophageal carcinoma can achieve better results in clinical response, though not in long-term local control or survival. The incidence of acute radiation esophagitis and pneumonitis is clinically acceptable.

ObjectiveTo measure the setup errors with infrared marker-based positioning system (IM-BPS) and electronic portal imaging device (EPID) for patients with esophageal carcinoma and lung cancer and investigate the accuracy and practicality of IM-BPS. MethodsFrom January 2007 to January 2008, 40 patients with esophageal carcinoma and 27 patients with lung cancer received three-dimensional conformal radiotherapy or intensity-modulated radiotherapy, setup errors during the treatment were measured with IM-BPS and EPID, and the data of setup errors were compared with paired t-test and agreement with x2-test. ResultsIt takes 10 - 12 mins to complete the validating for each patient by EPID) system, while IMBPS system only needs 2 -5 mins. The mean setup errors along x, y and z-axis for patients with esophageal carcinoma measured by IM-BPS and EPID were 3.49 mm, 3. 19 mm, 3.31 mm and 4. 03 mm, 3.41 mm, 3.43 mm, respectively. For the patients with lung cancer, the setup errors were 4. 23 mm, 3.51 mm, 3. 39mm and 4. 85 mm, 3. 53 mm, 3.74 mm, respectively. The difference of setup errors meanured by the two systems was within 1 mm for 65％ esophageal carcinoma patients ( x2 =51.09, P =0. 000), and 55％ lung cancer patients ( x2 =53. 35, P =0. 000).Conclusions The measurement results of setup errors for patients with esophageal carcinoma and lung cancer show that IM-BPS is mostly better than EPID. Though validating for patients can be measured accurately and be well quality controlled, IM-BPS is used easily because of macroscopic, homely,spare time and real-time monitoring.

Objective To predict the risk of neonatal hyperbilirubinemia by transcutaneous bilirubin (TcB) nomograms and clinical risk factors.Methods Healthy term and late-preterm newborns (≥ 35 gestational weeks,and birth weight ≥ 2 000 g) born in Guizhou Maternal and Child Care Hospital between January 1,2013 and December 31,2013,were included.TcB levels were continuously recorded within 168 hours after birth.The value of hour-specific TcB nomogram combined with receiver operating characteristic (ROC)curves and Logistic regression model for predicting risk of hyperbilirubinemia was evaluated.Pearson's Chisquare test was also used for statistical analysis.Results A total of 5 250 cases were enrolled.TcB increased rapidly in the first 40 hours after birth,slowly increased between 40 to 96 hours,and reached a high level after 96 hours.Among them,the 95th percentile TcB stablized at 96 hours after birth.The 40th,75th and 95th percentile TcB peak levels were 173,217 and 248 μmol/L.Among the 5 250 neonates,there were 277 cases (5.3％) in the high-risk zone within 72 hours.The positive predictive value (PPV) was 22.02％;1 087 cases (20.7％) and 1 854 cases (35.3％) were in the medium-high risk and medium-low risk zones along with the PPV of 10.58％and 3.72％,respectively.There were 2 032 cases (38.7％) in the low-risk zone with the PPV of 1.38％.Multivariate analysis showed that the TcB high-risk zone after 72 hours was associated with gestational age,delivery mode,feeding mode and TcB level of risk zones within 72 hours.Compared to those born at ≥ 40 gestational weeks,those born at ≥ 37-＜40 gestational weeks were more likely in the TcB high-risk zone after 72 hours (OR=1.80,95％CI:1.29-2.51).The likelihood was reduced by 42％ among neonates born with cesarean section compared to those delivered vaginally in term of the TcB high-risk zone after 72 hours.Infants who received mixed feeding were less likely to be in the TcB high-risk zone after 72 hours when compared to breastfed infants (OR=0.51,95％CI:0.29-0.88).With the reduction of the high-risk zone level within 72 hours,the likelihood in the TcB high-risk zone after 72 hours was also decreased.ROC curve showed that the area under the curve (AUC) for predicting hyperbilirubinemia was 0.75 and its 95％CI was 0.72-0.78,with a sensitivity of 90.00％ and specificity of 40.00％.The AUC of a combination of predictive results obtained by the Logistic regression model with significant variables in univariate analysis and high-risk zone after 72 hours was 0.66,and its 95％CI was 0.62-0.69.AUC estimated by Logistic regression model according to the TcB levels of risk zones within 72 hours combining with clinical risk factors was 0.79,and its 95％CI was 0.76-0.82 (P＜0.01).Conclusions Hour-specific TcB nomograms of newborns in our hospital have been obtained,which facilitates the prediction and early intervention of neonatal hyperbilirubinemia.

Objective To observe the incidence of RP in NSCLC and esophageal carcinoma treated with 3DCRT and investigate the relationship between acute RP and lung function and dosimetric parameters.Methods From October 2006 to August 2008, 3DCRT plus concurrent chemotherapy of NP or LFP were applied to 64 patients with locally advanced NSCLC or esophageal carcinoma. twenty-three patients suffered form NSCLC and 41 patients from esophageal carcinoma, the prescription doses were 60 Gy/30fx and 58 -64 Gy/29 -32fx, respectively. Results For patients with esophageal carcinoma, 34% developed RP(9 grade 1,3 grade 2 and 2 grade 3). For patients with NSCLC, 96% developed RP(9 grade 1, 8 grade 2 and 5 grade 3). There was significant difference between the two groups(t =5. 55,P=0. 000). The FEV1.0/FVC and DLCO of patients with NSCLC were significantly lower than those of esophageal carcinoma, the ratio were 75.6%:82.7%(t=2.75,P=0.008)and 71.7%:81.0%(t=2.50, P=0.015),respectively. For patients whose FEV1.0, FEV1.0/FVC%, DLCO ＜80% and ≥80% before irradiation,the incidence of ≥2grade ARP were 35% vs 25% ,31% vs 26% and 35% vs 19%, respectively(x2 = 1.81,0.15,2. 13,P =0.179,0.697,0.144). While for patients whose FEV1.0 ＜ 70% and ≥70%, the incidence of severe ARP were 67% and 22% ,respectively(x2 =5.64, P =0.018). Spearman correlated analysis indicated that all the dosimetric parameters had relation with ≥ 2 grade ARP . The V20 of lung and MLD were found independently associated with RP according to multivariate analysis(x2 = 4.61,6.97, P = 0.032,0.008).Conclusions Parameters of basic lung function can predict the incidence of ≥2 grade RP to some extent,especially when the value of FEV1.0, FEV1.0/FVC%, and DLCO was lower. However, the V20 of lung and MLD may be the most valuable predictors.

Objective To investigate the long-term survival of esophageal squamous cell carcinoma (ESCC) patients of different ages after three-dimensional conformal radiotherapy (3 DCRT).Methods From July 2003 to September 2008,769 patients with stage Ⅰ-Ⅲ ESCC were eligible for the analysis.All patients were treated with 3DCRT.The prescribed dose was 50-70 Gy (median,60 Gy),1.8-2.0 Gy per fraction,5 fractions per week.The Kaplan-Meier method was used to calculate overall survival (OS) and local control (LC) rates; the log-rank test was used for survival difference analysis and univariate prognostic analysis;the Cox regression model was used for multivariate prognostic analysis.Results The follow-up rate was 98.3％.For all patients,the 1-,3-,and 5-year LC rates were 76.3％,52.8％,and 48.5％,respectively,and the 1-,3-,and 5-year OS rates were 70.1％,36.2％,and 23.0％,respectively.The 1-,3-,and 5-year OS rates were 71.2％,38.8％,and 24.9％,respectively,for patients aged 45-74 years,versus 69.6％,26.6％,and 15.4％ for patients aged 75-89 years (P =0.008).Multivariate prognostic analysis showed that age was also a prognostic factor in ESCC patients after 3DCRT.A total of 620 patients died.Patients aged 45-74 years had a significantly higher proportion of individuals that died of distant metastasis (23.9％ vs.14.2％,P =0.009),while patients aged 75-89 years had a significantly higher proportion of individuals that died of non-cancer diseases (14.1％ vs.4.9％,P=0.000).Conclusions Survival varies between ESCC patients of different ages after 3DCRT.The survival of elderly ESCC patients is poor,and the relatively high mortality from non-cancer diseases may be an important reason for poor survival.

Objective To explore the surgical techniques and effects of one-stage reconstruction surgery for pediatric comminuted and depressed fractures of frontal bone and anterior skull base.Methods The clinical data of 13 pediatric cases with one-stage reconstruction surgery for comminuted and depressed fractures of the frontal bone and anterior skull base were reviewed retrospectively,including 8 male and 5 female,aged from 4 to 14 years,with a mean age of 8 years.Admission Glasgow Coma Scale (GCS) was as follows:3 to 8 scores in 2 cases,9 to 11 scores in 4 cases,and 12 to 15 scores in 7 cases.The intraoperative one-stage osseous and vascular pedicle membranous reconstruction of frontal bone and anterior skull base had been performed in all patients.The periosteum-bone fragments-periosteum had been used in 4 cases whose bony defect diameter of anterior cranial fossa was over 1 cm,multimodality therapy were carried out postoperatively.The follow-ups were regularly executed after discharge.Results GCS at discharge was as follows:3 to 8 scores in 1 case,9 to 11 scores in 2 cases,and 12 to 15 scores in 10 cases.No significant difference was found in GCS between those on admission and at discharge(χ2=3.02,P>0.05).Eleven cases had a phenomenon of nasal hemorrhage and the duration was not exceeding 48 hours.No intracranial infection and cerebrospinal fluid leakage occurred in all patients.All patients received an acceptable appearance without obvious frontal depre-ssion or proptosis.Postoperative computed tomography image showed normal cranial volume,well reset of fracture pieces,no fracture pieces existing in intracerebral tissue,satisfactory hematoma evacuation,and orbital contents without compression.The complications like cerebrospinal fluid leakage,poor incision healing,brain abscess or mucous cyst had not been found in all patients from 3 months to 6 years follow-up period.Conclusions The one-stage reconstruction surgery for pediatric comminuted and depressed fractures of frontal bone and anterior skull base suggests a better prognosis,effectively less complications,which helps to avoid secondary surgery,but regular follow-ups are absolutely necessary.This procedure is worth applying and spreading to pediatric patients and medical institutions if necessary.

Objective To discuss the effects of pressure control (PC) and positive end-expiratory pressure (PEEP) incremental method lung recruitment maneuver (RM) on haemodynamics in piglets with acute lung injury (ALI) induced by paraquat (PQ) poisoning. Methods The ALI/acute respiratory distress syndrome (ARDS) model was reproduced by intraperitoneal injection of 20% PQ (20 mL) in 10 healthy female piglets, and they were randomly divided into PC lung RM group (RM1 group) and PEEP incremental method lung RM group (RM2 group), with 5 piglets in each group. Heart rate (HR), mean arterial pressure (MAP), and cardiac index (CI) were monitored by pulse-indicated continuous cardiac output (PiCCO) monitoring before model reproduction (baseline), on the time of successfully set up of model and at 5, 15 and 30 minutes after RM. At the same time the arterial partial pressure of oxygen (PaO2) and arterial partial pressure of carbon dioxide (PaCO2) were recorded, and oxygenation index was calculated. Lung tissues were collected before model reproduction, on the time of successfully set up of model, and at 30 minutes after RM respectively, and pulmonary pathology changes were observed after hematoxylin and eosin (HE) staining under light microscopy. Results The HR, MAP, and PaCO2 on the time of successfully set up of model in both groups were increased obviously while CI, PaO2, and oxygenation index were decreased obviously as compared with those at baseline, all of which conformed to the expression of ALI/ARDS. With RM time extended, the HR in both groups was declined while MAP and CI were increased gradually. The HR and MAP at 5 minutes after RM of RM1 group were significantly lower than those of the RM2 group [HR (bpm): 126.8±5.2 vs. 134.0±3.8, MAP (mmHg, 1 mmHg = 0.133 kPa): 98.4±3.3 vs. 102.8±2.6, both P < 0.05]. The CI at 5 minutes and 15 minutes after RM of RM1 group was significantly higher than that of the RM2 group (mL·s-1·m-2: 56.7±5.0 vs. 46.7±6.7, 65.0±5.0 vs. 56.7±5.0, both P < 0.05). PaO2 and oxygenation index at 5 minutes after RM in both groups were significantly higher than those on the time of sucessfully set up of model. The PaO2 and oxygenation index were gradually decreased, and PaCO2 was increased with RM time extended, but no statistically significant differences at all time points were found between the two groups (all P > 0.05). The lung tissue in both groups showed a variety of pathological changes at 30 minutes after RM. The main performances were the loss of alveolar epithelial cells, the further wideness of alveolar interval and the distension of alveolar, and the part breakage of alveolar interval. The wideness of alveolar interval was more significant in RM2 group than that of RM1 group, and alveolar cleft was more common too. Conclusion Both PC and PEEP incremental method lung RM can improve the oxygenation of the piglets with ALI/ARDS induced by PQ, and the PC lung RM has less impact on haemodynamics.

Objective To investigate the feasibility of new criteria for evaluating the radiotherapeutic effect on esophageal cancer by barium meal (BM) combined with CT scans.Methods A total of 189 patients who were diagnosed with esophageal cancer (confirmed by biopsy) from January 2004 to December 2010 were enrolled as subjects.All patients underwent BM and CT scans before and after radiotherapy.The maximal esophageal wall thickness (EWT) and changes in the volumes of regional lymph nodes measured by CT scans were analyzed.New criteria for evaluating the short-term radiotherapeutic effect on esophageal cancer was studied considering the analysis results as well as the BM-based criteria for evaluating short-term radiotherapeutic effect and follow-up results.Results The BM-based evaluation criteria were still useful,but had certain limitations.There were 115 patients who had regional lymph node metastasis as detected by CT scans before radiotherapy,and they were divided into complete remission (CR) group and partial remission (PR) group according to BM results after radiotherapy; the local control rate (LCR) of CR group was significantly higher than that of PR group,but there was no significant difference in survival rate (SR) between the two groups.There were 65 patients who had no regional lymph node metastasis,and they were also divided into CR group and PR group according to BM results after radiotherapy;the LCR and SR of CR group were significantly higher than those of PR group.In summary,the patients who had a CR as evaluated by BM and had the maximal EWT of ≤ 1.20 cm and the volumes of residual lymph nodes of ≤ 1.00 cm3 on CT were defined as CR ; the patients who had a PR as evaluated by BM or had the maximal EWT of ＞ 1.20 cm or those who had a CR evaluated by BM and had the maximal EWT of ≤ 1.20 cm and the volumes of residual lymph nodes of ＞ 1.00 cm3 on CT were defined as PR.The cases evaluated by BM as no remission (NR) or showing metastasis were defined as NR or progressive disease.There were significant differences in LCR and SR between the CR group and PR group determined by the new criteria.Conclusions Simply using BM to evaluate the short-term radiotherapeutic effect on esophageal cancer has certain limitations; instead,the evaluation based on both BM and CT scans is more accurate.

Objective To observe the acute side effects, local control rate and survival rate of concurrent chemoradiotherapy (CC) and radiotherapy alone (R) for patients with esophageal carcinoma.Methods From June 2006 to February 2009, 209 patients with esophageal carcinoma were observed, 105 of them were treated with CC.Of all the patients, 117 received three-dimensional conformal radiotherapy, 92 received intensity modulated radiotherapy, the median prescription dose was 60 Gy.The regimen of LFP (5-FU, cisplatin and calcium folinate) was selected for this study, side effects, local control rate and survival rate were observed and subsets analysis were performed.Results The overall follow-up rate was 99.0%,there were 99 and 44 patients whose follow-up time was more than 2 and 3 years, respectively;for the CC group, the data were 45 and 14, respectively;and for the R group, 54 and 30, respectively.The 1-,2-,3-year local control rates of CC group and R group were 88.1%,69.2%,66.2% and 81.0%,64.0%,54.9%(χ2=2.31,P=0.128), respectively.The 1-,2-,3-year overall survival rates of CC group and R group were 84.4%,52.9%,45.6% and 75.2%,50.7%,37.0%(χ2=1.57,P=0.210),respectively.Subset analysis indicated that for the patients of N0 group and whose length of GTV>7 cm, the local control rate of CC was significantly higher than that of radiotherapy alone (χ2=5.11,7.66;P=0.024, 0.006).For N0 group, the survival rate of CC was higher than that of R alone.(χ2=5.07,P=0.024).The incidence of WBC, PLT and HGB reduction for the two groups were 81.9% and 49.0%(χ2=36.45,P=0.000),14.3% and 1.9%(χ2=10.54,P=0.006),and 24.8% and 2.9%(χ2=22.95,P=0.000),respectively.The incidence of nausea, vomiting and constipation for the two groups were 63.8% and 7.7%(χ2=71.52,P=0.000), respectively.The incidence of ≥2 grade esophagitis of CC group and R group were 48.57% and 38.46%(χ2=2.17,P=0.141), respectively.The incidence of ≥2 grade radiation pneumonitis of CC group and R group were 15.24% and 7.69%(8/104)(χ2=2.93,P=0.087),respectively.ConclusionsCompared to radiotherapy alone, the local control rate and overall survival rate of concurrent chemoradiotherapy were not improved significantly, the patients with N0 may be the conspicuous beneficiary.About side effects, only marrow depression and gastrointestinal tract reaction were significantly different between the two groups,the value of addition of concurrent chemoradiotherapy for esophageal carcinoma needs further investigation.
