The precise surgical treatment for hepatobiliary diseases has been a challenging topic in hepatobiliary surgery for a long time.A perfect preoperative plan can help the surgeon make R0 resection of the lesion and preserve the healthy tissue as much as possible.In addition,all of these depend on the application of different imaging modalities,especially three-dimensional reconstruction technique.But some limitations of 3D reconstruction should be noted:different surgeons may have different views for one object because of different observation points;or it cannot be used for intraoperative re-orientation and so on.3D printed model can overcome some disadvantages of 3D reconstruction.This paper reviewed related literature that reported the usage of 3D printed model in hepatobiliary surgery.

Objective To study the surgical treatment and the related risk factors of cholangioenterostomy anastomotic stenosis.Methods We retrospectively analysed the clinical data of 41 patients who underwent surgical treatment for cholangioenterostomy anastomotic stenosis in the PLA General Hospital from January 1,2008 to November 30,2014.Results All patients' clinical symptoms were alleviated and they were discharged home.No one died perioperatively.Anastomotic restenosis happened in 5 patients.Conclusions Reoperation for cholangioenterostomy anastomotic stenosis was difficult.The surgeon should make the anastomosis as large as possible to decrease the risk of restenosis.A T tube should be used when necessary.

Objective To investigate the ultrasonic performance of carotid atherosclerotic plaque and the correlation between microvessel density in plaque .Methods 87 cases of patients undergoing carotid artery plaque dissection were selected .113 plaques were found .All patients were taken carotid color Doppler sonography test and analysis of the plaque .The maximum thickness of plaques was taken HE stained ,and the vessel density in the plaque was counted .The correlation with sonographic performance of plaques was analyzed .Results The maximum plaque thicknesses in hard plaque ,soft plaque and mixed plaque were (0.49 ±0.05)mm,(0.36 ±0.08)mm and (0.39 ± 0.10)mm,respectively,and cross-sectional area stenosis rates were (88.32 ±6.51)%,(68.92 ±12.05)% and (71.95 ±13.04)%,respectively,the differences were statistically significant (F=16.329,23.723,all P<0.05). The maximum plaque thickness and cross -sectional area stenosis rate in hard plaque were all larger than soft plaque and mixed plaque,the differences were statistically significant (t=7.091 7,2.501 and 6.452,6.086,all P<0.05). The microvessel density values in different plaques were (2.11 ±0.48)strips/mm2,(5.91 ±1.03)strips/mm2 and (3.82 ±0.99)strips/mm2,the differences were statistically significant (F=143.541,P<0.05),soft plaque>mixed plaques>hard plaque,the differences were statistically significant (t=6.579 and 9.392,all P<0.05).Pearson cor-relation analysis showed that the maximum plaque thickness and cross -sectional area stenosis rate in soft plaque were positive correlation between microvascular density values (r=0.372,P=0.011;r=0.438,P=0.000).Conclusion Color Doppler ultrasound examination might indirectly reflect microvessel densities in carotid artery plaque .It could be used preliminary assessment of vulnerability of carotid artery plaque .

Objective To observe the therapeutic efficacy of acupuncture at the interiorly-exteriorly related meridians plus rehabilitation training in treating post-stroke shoulder-hand syndrome. Methods Sixty eligible patients with post-stroke shoulder-hand syndrome were randomized into a treatment group and a control group, 30 in each group. The treatment group was intervened by acupuncture at the interiorly-exteriorly related meridians plus rehabilitation training, while the control group was by rehabilitation training alone. After 2 treatment courses, the Fugl-Meyer Assessment (FMA), visual analogue scale (VAS) and edema score were observed and compared. Results The FMA, VAS, and edema scores were significantly changed in both groups after intervention (P＜0.01). There were significant differences in comparing the FMA, VAS, and edema scores between the two groups after intervention (P＜0.05). The total effective rate was 83.3%in the treatment group versus 76.7%in the control group, and the difference was statistically significant (P＜0.05). Conclusion Acupuncture at the interiorly-exteriorly related meridians plus rehabilitation is an effective method in treating post-stroke shoulder-hand syndrome.

Objectives:To observe growth suppressive effects of human wild type p53(wt p53) gene on human esophageal cancer cell line. Methods:Using the retroviral vector to introduce exogenous wt p53 gene into human esophageal cancer cell line ECA109,the gene expression and tumor inhibition were studied in vitro and in vivo . Results:The expression of p53 in transfected cell lines(ECA 109/p53 ) was increased.The growth rates and the ability to form colony in soft agar were greatly inhibited in ECA 109/p53 cells versus ECA109/neo and ECA109 cells.The G 0+G 1 ratio increased and S ratio decreased in cell cycle distribution,and apoptosis index significantly rose in the ECA109/p53 cells,which were confirmed by FCM analyzing.The tumorigen icity of ECA109/p53 cells in nude mice was obviously suppressed by exogenous p53. Conclusions:Exogenous wt p53 mediated by retroviral vector could inhibit the growth of human esophageal cancer cell.

Objective To evaluate the efficacy and safety of concomitant docetaxal (DTX) and nedaplatin (NDP) therapy for recurrent epithelial ovarian cancer in elderly women.Methods Totally 42 elderly patients with histologically confirmed recurrent epithelial ovarian cancer received chemotherapy with DTX combined with NDP.DTX with the dose of 60-70 mg/m2 was administered intravenously on day 1,followed by NDP with the dose of 70-80 mg/m2 given intravenously on day 2.The treatment was repeated every 3 weeks.The efficacy was evaluated according to response evaluation criteria in solid tumors (RECIST) and serum CA125 level.Adverse reactions were assessed according to performance and standard criteria in toxicity of anticancer agents of WTO.Results 4 patients were switched to other chemotherapy strategies due to progression of disease after 2 courses of treament,and the other patients completed 4 to 6 courses.Among 42 patients,18 cases (42.9％)showed complete remission,10 cases (23.8％) showed partial remission,6 cases (14.3％) were in stable conditions,and 8 cases (19.0％) progressed to severe disease.The median progression-free survival (PFS) time was 7 months,and the efficacy rate (complete and partial remission) was 66.7％(28/42).The main adverse effects were alopecia,nausea and vomit,and leucopenia.Patients could get remission by receiving drug therapy.Conclusions Docetaxel plus nedaplatin therapy has a good therapeutic effect with low incidence of adverse reactions,high safety and well tolerance in elderly platinum-sensitive women and in those with platinum-resistant recurrent epithelial ovarian cancer.

Objective To investigate the effects of exercise therapy and health education on the hospitalization and exercise endurance of patients with moderate or severe chronic obstructive pulmonary disease (COPD).Methods A total of 86 patients with moderate or severe but stable COPD were divided randomly into an observation group (n=46) and a control group (n=40).The patients in both groups accepted general respiratory medical therapy.The patients in the observation group also accepted additional pulmonary rehabilitation therapy which consisted of exercise and health education while the patients in the control group only accepted health education and rehabilitation training guidance by telephone instead of standardized pulmonary rehabilitation therapy.The average recurrence of hospitalization,length of stay,and total bed time of all of the patients was tracked for a year before and after enrolment.Their 6 minute walking distance (6MWD) and quality of life (QOL) as reflected by using a scale recommended by the Chinese Society of Respiratory Disease before and after entering the study were evaluated.Results There was no significant difference between the groups in the year before entering the study in terms of their average frequency of hospitalization,length of stay or total bed time.In the year after enrollment average frequency of recurrence requiring hospitalization,length of stay and total bed time in the observation group all decreased significantly compared with the previous year,and all were significantly lower than in the control group.There were no significant differences between the groups in average 6MWD or average QOL score at entry,but in the subsequent year both groups' results improved significantly.Conclusion Long term pulmonary rehabilitation can not only enhance exercise endurance,it also improves QOL and relieves the economic burden of COPD patients on society.

A sensitive method was developed for the determination of pacific ciguatoxin (P-CTX1) residue in fishes by high performance liquid chromatography coupled with electrospray tandem mass spectrometry ( HPLC-MS/MS). Homogenized samples of fish was extracted with acetone,degreased by freezing under -20℃ and filtered with filter paper. Then the supernatant was cleaned up with PSA column. Identification was achieved by electrospray ionization (ESI) in positive mode using multiple reaction monitoring. The calibration curve of P-CTX1 showed good linearity in the range of 0.5 -20μg/L with correlation coefficient of 0.9998. The limit of quantitation (LOQ) was 0. 1 mg/L( S/N = 10). The recoveries of P-CTX1 were between 82. 3% and 87. 2% (n =7) at spiked levels of 1.0 -20.0 ng/kg. The relative standard derivations( RSD) of the method were less than 7.8%.
