Results All cases were Dukes D stage or accompanied with hepatic metastasis. Hartmann's operation was performed in 26 cases, single lumen sigmoidostomy in 11 cases, double lumen sigmoidostomy in 11 cases and resection of hepatic metastatic cancer in 12 cases. Rectal upper arterial catheter chemotherapy was performed in 19 cases and hepatic arterial catheter chemotherapy in 15 cases. The 3-year survival rate of Hartmann's operation was 34%(9/26), and the average survival time was 20?3.17 months in the patients underwent rectal upper and hepatic arterial catheter chemotherapy, and 10?1.77 months in the patients who could not be treated surgically(P

Objective To study the effect of modified periocular injection on the pains induced by local application of drugs. Methods Sixty patients treated with periocular injection were divided randomly into experimental group and control group in equal number. The control group was treated with orthodox periocular injection,while experimental group with modified periocular injection, immersing the pinhead into lidocaine solution before injection.The pain level of patients was evaluated by self-designed pain scale. Result The pain level of modified periocular injection was lower than that of orthodox periocular injection statistically (Z=3.799, P<0.001).Conclusion Modified periocular injection can alleviate pains induced of local application of drugs obviously and increase their compliance,so it deserves clinically popularizing.

Objective To investigate the application value of anatomic segmental hepatectomy in treatment of left hepatolithus.Methods The 80 patients with left hepatolithuswere divided into the control group (n =40)and the observation group (n =40)in accordance with dif-ferent surgical methods,and they were given traditional surgery and precise pedicle anatomic segmental hepatectomy respectively.Operation index levels,postoperative complications and stress reaction levels before and after surgery of the two groups were compared.Results The blood loss,operative time,the time of drainage tube remove,time of analgesic drug use,and postoperative hospital stay of the observation group were significantly less than the control group,and the difference was statistically significant (P <0.05).The rate of postoperative com-plications was 17.50% in the control group,while it was 15.00% in the observation group,which showed no significant difference between the two groups (P >0.05).During the surgery,epinephrine,cortisol,IL-6 and CRP levels of patients decreased after a slight increase, while NK cell levels of patients decreased firstly and then increased.There were statistically significant differences in trems of the above inde-xes immediately after surgery to 24 hours after surgery (P <0.05),and the rangeability of the observation group was less than the control group (P <0.05).Until 48 hours after surgery the above indexes recovered to the preoperative level.Followed up for 3 to 24 months,the calculi recurrence rate and abdominal ache recurrence rate of the observation group were lower than the control group,and the difference was statistically significant(P <0.05).Conclusion Precise pedicle anatomic segmental hepatectomy applied in the treatment of left hepatolithus showed makedly curative effect,and it has little effect on the stress response of patients.

Objective To explore the effect and safty of interventional embolization of congenital arteriovenous fistula (CAVF) in the common femoral profounda artery in children.Methods Eight children (aged 6 to 14 years ;6 males and 2 females) with CAVF underwent interventional embolization From January 2006 and December 2010.Color Doppler sonography and DSA were performed on all patients.Arterial duplex imaging revealed the arteriovenous fistula in the common femoral profounda artery and DSA further confirmed the presence of an AVF over the common femoral profounda artery via the other vein.All children were treated with interventional embolization therapy by the injection ofcoils or ethanol through a microcather.It was necessary to performed repeated interventional embolization if the lesion was not obliterated in 4 weeks.All patients were followed-up from 6 months to 2 years and the clinical symptoms were observed.Results Arteriograpy can clearly demonstrate the femoral profounda artery and its branches as well as the fistula.Ten interventional embolization procedures were performed.Forty seven coils were deployedduring the procedure and seven ethanol embolization procedures were performed.Post-procedural angiography revealed complete occlusion in 8 patients.No major complications such as ectopic coil embolization,tissue necrosis,peripheral nerve palsy or cardio-pulmonary collapse were found.The abnormal AVFs were embolized completely in 7 cases after only one therapy and there was no recurrent disease in the 6 months to 2 years follow-up.Some tiny AVFs were still found in another case which underwent three additional treatments.However,the clinical symptoms were under control.Conclusion Interventional embolization is a safe and effective therapeutic method for CAVF of the common femoral profounda artery in children and it might become the primary treatment option.

BACKGROUND:The osmotic tissue expander is a self-fil ing device consisting of an osmotic active hydrogel which is made of vinylpyrrolidone and mehtylmethacrylate. It can absorb body fluids and swel up gradual y after embedded.
OBJECTIVE:To explore the short-term and long-term regular patterns as wel as histocompatibility of the osmotic tissue expander in vivo.
METHODS:A self-control design was carried out in Wistar rats by embedding the osmotic tissue expander and high-density polyethylene into each side of their spinal column subcutaneously. Wound healing, tissue expansion and inflammatory reaction were detected and compared at different periods after operation.
RESULTS AND CONCLUSION:Al the wounds got primary healing. The device expanded fastest at week 1 after the implantation. After being enlarged to about nine times that of the initial size at week 4, the expander slowed down its swel ing. It reached its ultimate volume at week 12 which was about 10 times as big as that of the initial one. Then it remained almost the same size until the end of our design. Pathological sections showed that the inflammatory reaction of osmotic-tissue-expander-group had no significant difference from that of the control group (P>0.05). These findings suggest that osmotic tissue expander has a slow-lasting swel ing ability and good histocompatibility.

ObjectiveTo evaluate and compare the curative effect and the safety of sclerotherapy of venous malformation in children using absolute ethanol and pingyangmycin.MethodsEighty children with venous malformation were treated by sclerotherapy with absolute ethanol or pingyangmycin under general anesthesia during February of 2009 to May of 2011. Diagnostic criteria included the presence of a bluecolored lesion at birth,with gradual increase in its size associated with a positive postural test.MRI showed characteristic imaging features.Eighty patients were divided into two groups by randomization.Forty patients were treated with absolute ethanol,and the remaining 40 patients with pingyangmycin. The therapeutic effects and side effects were observed and recorded during a follow-up period of 6 to 24 months ( average 15 months).Treatment results weredividedinto four categories: cure, basiccure, effective, and ineffective,and the former three categories were considered effective in treatment.Chi-square test was used to compare the rate of effective treatment and rate of complications in these two groups.ResultsThe effective patients treated with absolute ethanol was 38 (95.0％,38/40),and the effective patients with pingyangmycin was 26(65.0％,26/40),x2 test ( x2 =11.25,P ＜ 0.01 ) difference was statistically significant.Eight patients developed skin necrosis; 4 patients serious local swelling,2 patients muscle fibrosis,1 patient cerebral embolism in the absolute alcohol group.Two patients developed postoperative fever and vomiting and 2 skin necrosis in the pingyangmycin group,the difference was statistically significant (x2 =12.29,P ＜0.01 ). ConclusionsSclerotherapyiseffectiveforthetreatmentofvenousmalformationsin children.Absolute ethanol is more effective,but associated with more complications,such as skin necrosis or as serious as cerebral embolism,than pingyangmycin.

To study the regulating effect of Astragalus Polysaccharides ( APS) to the mice infected by Brucella suis S2.Methods:120 BALB/c mice were randomly divided into 4 groups:experimental mice were injected APS 1 ml ( 0.4,1.2,3 mg/ml) via peritoneal cavity respectively once a day and the control group was injected with the same volume of saline for 3 days,then infected with Brucella suis S2 1 ml (1×107 L-1 ) by ip.Five mice of each group were killed through eye bloodletting at 1,6,12,24,48, 72 h respectively post-infection with Brucella suis S 2 and the peritoneal macrophage were obtained respectively to make smear.Phagocytic rate and phagocytic index were calculated by the Wright Giemsa staining after infected 1 h.TNF-α,IL-12 and IFN-γlevels of serum at different time points were measured by ELISA.The bacterial load of MΦand spleen were measured by coating method.Results:The phagocytic rate and phagocytic index of MΦin APS 3 dose groups were higher than those of the control group ( P<0.05 ).The microbial load of MΦin APS 3 dose groups at 1 h infected by Brucella suis S 2 were significantly higher than those of control,but significantly lower than those of control at 6,12,24,48,72 h after infected by Brucella suis S2.The microbial load of spleen in APS 3 dose groups at 6 h infected by Brucella suis S 2 were significantly higher than those of control ,but significantly lower than those of control at 12,24,48,72h after infected by Brucella suis S2.The concentrations of TNF-α,IL-12 and IFN-γin the serum of APS groups had significantly been improved ( P<0.05 ).Conclusion: APS can promote the activation of MΦin vivo and strengthen the activity of phagocytosis and killing to Brucella suis S 2.APS can promote the secretion of TNF-α,IL-12 and IFN-γof mice,strengthen the cellular immune response of mice to Brucella suis S 2.

Background Lattice corneal dystrophy (LCD) is a progressive disease,whose clinical features are varied in different stages.It is rarely be reported that clinical findings of different stages and factors of promoting the occurrence and development on LCD in a family.Objective The aim of this study was to identify the characteristics of the pedigree and clinical features of different stages in a LCD family,and further to discuss its influence factors.Methods A cross-sectional study was performed in this study.A Chinese family with LCD was enrolled in Shenzhen Eye Hospital from 2015 to 2016.Questionnaires for disease-related history,visual acuity measurement,ocular anterior segment examination and color photography were carried out for all the members of the family.In addition,anterior segment OCT (AS-OCT),laser scanning confocal microscope and corneal endothelium microscope were used to observe the morphology of corneal stroma and changes of corneal endothelial cells.The pedigree chart was drawn by Cyrillic2.1 software and analyzed based on Mendel law.Results This family included 5 generations of 73 members.Patients with LCD were found in each generation with similar morbidity in different gender,which followed the law of autosomal dominant inheritance.Eleven patients were found in 49 members related with Ⅲ1 of this family with the prevalence rate of 22.45％ and onset age at 21-50 years old,and the course of disease was 3-34 years.All of the members had no systemic disease except for two patients (Ⅲ 1 and Ⅲ 5) with hypertension.In the early stage of LCD,some bifurcate striolae appeared in the patients' corneal stroma without symptoms for many years.In the progressive stage,there was corneal irritation symptom accompanying with vision's decrease in the eyes with LCD.The bifurcate striolae were increased,widened and interwoven into lattice lines that the boundaries gradually became fuzzy,then corneal macula was formed because of recurrent corneal infiltration,and eventually resulted in corneal leucoma.High reflection corresponding to the pathologic region was showed by laser scanning confocal microscope and AS-OCT.No significant differences were found in corneal endothelial cell density and the percentage of hexagonal cells between LCD patients and normal phenotype families (t =1.887,P=0.075;t=-0.719,P =0.481).Penetrating keratoplasty was performed in a patient with corneal opacity and serious corneal opacity occurred near the surgical incision one year after the surgery.One patient was diagnosed as LCD 2 years after laser assisted in-situ keratomileusis.One patient was a welder.Conclusions LCD is autosomal dominant inheritance in the family.The clinical manifestations of LCD in the early,progressive and late stage can be seen in the pedigree,which offers a reference for ophthahnologists.Corneal surgery and lesion may induce the onset or aggravation of LCD.
