ABSTRACT
Objective To observe the changes of optic disc structure and retinal nerve fiber layer thickness (RNFL) in patients with different degrees of Parkinson's disease (PD).Methods Thirty eyes of 30 patients with primary PD and 20 eyes of 20 healthy subjects (control group) in Xuanwu Hospital of Capital Medical University from October 2016 to October 2017 were enrolled in this study.The patients were divided into mild to moderate PD group (15 eyes of 15 patients) and severe PD group (15 eyes of 15 patients).All the patients underwent OCT examination.The optic disc area,cup area,C/D area ratio,rim volume,disc volume,cup volume,rim area,C/D area,linear C/D,vertical C/D,the thickness of average RNFL,superior,inferior,temporal upper (TU),superior temporal (ST),superior nasal (SN),nasal upper (NU),nasal lower (NL),inferior nasal (IN),inferior temporal (IT),temporal lower (TL) quadrant RNFL thickness.Analysis of variance was performed for comparison among three groups.Minimum significant difference t test was performed for comparison between two groups.Results Optic disc structure parameters:there was no significant difference in the area of optic disc between the three groups (F=1.226,P＞0.05).The other optic disc parameters were significantly different in the three groups (F=5.221,5.586,6.302,5.926,5.319,5.404,5.861,6.603;P＜ 0.05).The cup area,cup volume,C/D area,linear C/D,vertical C/D of the mild to moderate PD group and severe PD group were higher than that of the control group (P＜0.05).The cup area,cup volume,C/D area,linear C/D,vertical C/D of the severe PD group were higher than those of mild to moderate PD group (P＜ 0.05),the rim area,rim volume and disc volume of the severe PD group were smaller than that of mild to moderate PD group (P＜ 0.05).The thickness of RNFL:there was no significant difference between the three groups of ST,SN,NU and NL (F=3.586,2.852,2.961,2.404;P＞0.05).The average thickness of RNFL,TU,IN,IT and TL in patients of the mild to moderate PD group and severe PD group were less than that in the control group (P＜0.05).The thickness of the average RNFL,TU,IN,IT and TL in patients of the severe PD group were less than that in the mild to moderate PD group (P＜0.05).With the increase of PD severity,the RNFL of TL and TU thinned most significantly.Conclusions With the increase of the severity of PD,the optic disc structure and RNFL thickness changes obviously,showing reduced optic disc area and volume,enlarged cup area and volume significantly enlarged C/D ratio.The average RNFL thickness of PD patients is significantly thinner than that of the controls,and it is the most obvious in the TU and TL quadrant.
ABSTRACT
Objective To observe the macular retinal thickness and volume in patients with different degrees of Parkinson's disease (PD).Methods Thirty eyes of 30 patients with primary PD and 20 eyes of 20 healthy subjects (control group) in Xuanwu Hospital of Capital Medical University from October 2016 to October 2017 were enrolled in this study.There were 17 males and 13 females,with the mean age of 63.2±6.4 years and disease course of 3.9± 2.4 years.The patients were divided into mild to moderate PD group (15 eyes of 15 patients) and severe PD group (15 eyes of 15 patients).The macular area was automatically divided into 3 concentric circles by software,which were foveal area with a diameter of 1 mm (inner ring),middle ring of 1 to 3 mm,and outer ring of 3 to 6 mm.The middle and outer ring were divided into 4 quadrants by 2 radiations,respectively.The changes of retinal thickness and macular volume of the macular center and its surrounding quadrants were analyzed.SPSS 16.0 software was used for statistical analysis.One-way ANOVA were used to analyze all data.Results Compared with the control group,the retinal thickness and volume in macular center and each quadrant of the mild to moderate PD group and severe PD group were reduced.Compared with the mild to moderate PD group,the retinal thickness and volume in macular center and each quadrant of the severe PD group were reduced.The differences of retinal thickness and macular volume among 3 groups were significant (F=5.794,5.221,5.586,5.302,5.926,5.319,5.404,5.261,5.603;P=0.001,0.007,0.003,0.005,0.000,0.004,0.004,0.006,0.002).In inner ring of the mild to moderate PD group and the severe PD group,the retinal thickness and macular volume in the upper and the nasal were the largest,the inferior was followed,and the temporal was the smallest.In outer ring of the mild to moderate PD group and the severe PD group,the retinal thickness and macular volume in the nasal was the largest,the upper was the second,the temporal and the inferior were the smallest.Conclusions The retinal thickness and volume of the macular central fovea and its surrounding areas in PD patients are significantly thinner than that in the healthy subjects.And with the increase of the severity of PD,the macular structure changes obviously,showing macular center and its surrounding macular degeneration thin,macular volume reduced.
ABSTRACT
Objective To compare the clinical characteristics and the outcomes of severe hyperlipidemic pancreatitis (SHLP) and severe acute gallstone pancreatitis (SAGP).Methods The clinical data of 22 patients with SHLP and 91 patients with SAGP admitted from January 2009 to December 2015 were retrospectively reviewed.The clinical manifestations,laboratory tests,organ dysfunction,medical treatment,complications and outcomes in 30 d after admission were analyzed and compared between two groups of patients.Results There were 16 males and 6 females with a mean age of (60.5 ± 9.1) years in SHLP group;while 32 males and 59 females with a mean age of (54.3 ± 5.4) years in SAGP group.The blood and urine amylase levels in SHLP group were significantly lower than those in SAGP group [(715 ±99) U/L vs.(1 551 ± 107) U/L,t =4.65,P =0.00;(382 ±56) U/L vs.(773 ± 66) U/L,t =4.52,P =0.00,respectively].The incidence of circulation insufficiency,respiratory insufficiency,renal dysfunction,and long-term puhnonary infection in SHAP patients was significantly higher than that in SAGP patients [36 ％ (8/22) vs.14 ％ (13/91),x2 =5.22,P =0.01;41％ (9/22) vs.7 ％ (6/91),x2 =9.46,P =0.01;23％(51/22) vs.5％ (5/91),x2 =4.20,P=0.03;55％(12/22) vs.32％ (29/91),x2 =7.02,P =0.01].Two cases died in the SHLP group and 9 cases died in SAGP group due to critical infection,cardiac events and bleeding.Conclusion Compared to SAGP patients,the blood and urine amylase levels are usually not remarkably high in SHLP patients,and the prevention and management of multi-organ failure and lung infection are more important for SHLP patients.
ABSTRACT
Objective To observe the changes of macular choroidal thickness before and after laser treatment for diabetic retinopathy patients.Methods For patients with diabetes by fundus fluorescein angiography (FFA) examination,diagnosed as severe non-proliferative and proliferative diabetic retinopathy and in accordance with the laser photocoagulation treatment indications of 23 patients (45 eyes) included in the study.There were 10 cases of male,13 cases of female; the average age was (55.48±5.43) years old.All patients underwent macular grid laser photocoagulation and pan-retinal photocoagulation.The macular choroidal thickness before and after laser treatment was measured by enhanced depth imaging technique of optical coherence tomography during follow-up at 1,2,3 weeks and one month at specific sites of choroidal.The specific sites included subfoveal choroidal thickness (SFCT),from the foveal 1mm,3mm,6mm distance of nasal choroidal thickness (NCT) and temporal choroidal thickness (TCT).Results One week after the treatment,SFCT,NCT1 mm,NCT3 mm,TCT1 mm,TCT3 mm,TCT6 mm were obviously thickening (t=4.728,4.422,3.759,3.743,5.713,2.502; P＜0.05).Two weeks after the treatment the SFCT,NCT1 mm,NCT3 mm,TCT1 mm,TCT3 mm were decreased gradually (t =3.189,2.122,2.742,2.196,2.076 ; P＜0.05).The choroidal thickness returned to pretreatment level from 2 weeks to 4 weeks after treatment,the NCT6mm had no obvious change in the whole treatment period(P＞0.05).Conclusion The choroidal thickness was significantly thicker after laser photocoagulation treatment within 1 week,with the time prolonging the choroidal thickness gradually decreases.
ABSTRACT
<p><b>BACKGROUND</b>Lowering intraocular pressure (IOP) is currently the only therapeutic approach in primary open-angle glaucoma. and the fixed-combination medications are needed to achieve sufficiently low target IOP. A multicenter prospective study in the Chinese population was needed to confirm the safety and efficacy of Bimatoprost/Timolol Fixed Combination Eye Drop in China. In this study, we evaluated the safety and efficacy of Bimatoprost/Timolol Fixed Combination with concurrent administration of its components in Chinese patients with open-angle glaucoma or ocular hypertension.</p><p><b>METHODS</b>In this multicenter, randomized, double-masked, parallel controlled study, patients with open-angle glaucoma or ocular hypertension who were insufficiently responsive to monotherapy with either topical β-blockers or prostaglandin analogues were randomized to one of two active treatment groups in a 1:1 ratio at 11 Chinese ophthalmic departments. Bimatoprost/timolol fixed combination treatment was a fixed combination of 0.03% bimatoprost and 0.5% timolol (followed by vehicle for masking) once daily at 19:00 P.M. and concurrent treatment was 0.03% bimatoprost followed by 0.5% timolol once daily at 19:00 P.M. The primary efficacy variable was change from baseline in mean diurnal intraocular pressure (IOP) at week 4 visit in the intent-to-treat (ITT) population. Primary analysis evaluated the non-inferiority of bimatoprost/ timolol fixed combination to concurrent with respect to the primary variable using a confidence interval (CI) approach. Bimatoprost/timolol fixed combination was to be considered non-inferior to concurrent if the upper limit of the 95% CI for the between-treatment (bimatoprost/timolol fixed combination minus concurrent) difference was ≤ 1.5 mmHg. Adverse events were collected and slit-lamp examinations were performed to assess safety. Between-group comparisons of the incidence of adverse events were performed using the Pearson chi-square test or Fisher's exact test.</p><p><b>RESULTS</b>Of the enrolled 235 patients, 121 patients were randomized to receive bimatoprost/timolol fixed combination and, 114 patients were randomized to receive concurrent treatment. At baseline the mean value of mean diurnal IOP was (25.20 ± 3.06) mmHg in the bimatoprost/timolol fixed combination group and (24.87 ± 3.88) mmHg in the concurrent group. The difference between the treatment groups was not statistically significant. The mean change from baseline in mean diurnal IOP (± standard deviation) in the bimatoprost/timolol fixed combination group was (-9.38 ± 4.66) mmHg and it was (-8.93 ± 4.25) mmHg in the concurrent group (P < 0.01). The difference between the two treatment groups (bimatoprost/timolol fixed combination minus concurrent) in the change from baseline of mean diurnal IOP was -0.556 mmHg (95% CI: -1.68, 0.57, P = 0.330). The upper limit of the 95% CI was less than 1.5 mmHg, the predefined margin of non-inferiority. Adverse events occurred in 26.4% (32/121) of the bimatoprost/timolol fixed combination patients and 30.7% (35/114) of the concurrent patients. The most frequent adverse event was conjunctival hyperemia, which was reported as treatment related in 16.5% (20/121) in the bimatoprost/timolol fixed combination group and 18.4% (21/114) in the concurrent group (P > 0.05).</p><p><b>CONCLUSIONS</b>Bimatoprost/Timolol Fixed Combination administered in Chinese patients with open-angle glaucoma or ocular hypertension was not inferior to concurrent dosing with the individual components. Safety profiles were similar between the treatment groups.</p>

Background Vitrectomy is an effective method to proliferative diabetic retinopathy (PDR) in type 2 diabetic patients.Postoperative vitreous hemorrhage is a major cause of vision loss.Objective This study was to analyze the related factors of vitreous hemorrhage after vitrectomy in proliferative retinopathy with type 2 diabetes.Methods Three hundred and five eyes of 305 cases who received vitrectomy for PDR from type 2 diabetes were retrospectively investigated.The clinical data of 14 eyes with vitreous hemorrhage after vitrectomy were analyzed.Results Vitreous hemorrhage after vitrectomy occurred in 14 eyes with the incidence 4.6％.The PDR was grade ⅣV in 3 eyes,grade Ⅴ in 4 eyes and grade Ⅵ in 7 eyes.Pars plana vitrectomy with intraocular laser photocoagulation was performed on all the 14 eyes,and 1 eye accepted scleral condensation and 8 eyes accepted silicone oil tamponade.Visual acuity was improved in 6 eyes,unchanged in 4 eyes and worsen in 4 eyes after initial surgery.Vitreous hemorrhage appeared in postoperative 1-7 days in 9 eyes,8 days-3 months in 1 eye,3-6 months in 2 eyes and over 6 months in 2 eyes.The cause for postoperative vitreous hemorrhage included residual neovascular membrane,insufficient photocoagulation range and intensity,neovascularization and instable blood glucose level.Vitreous hemorrhage disappeared in 5 eyes after medicine therapy,and reoperation in 9 eyes.In the end of the follow up,visual acuity improved in 9 eyes,unchanged in 2 eyes and worsen in 3 eyes.Retinas reattached in 13 eyes.However,the retina was still detached in 1 eye with silicone oil tamponade.Conclusions Postoperative vitreous hemorrhage usually occurs within 1 week.The main related factors are residual retinal neovascular membrane,inadequate intraocular laser photocoagulation and unstable blood glucose level.Medicine therapy is effective for postoperative vitreous hemorrhage in type 2 diabetic patients,but re-vitrectomy is needed for excessive vitreous bleeding.
ABSTRACT
Objective To observe the influence of early intestinal barrier protection in patients with severe acute pancreatitis(SAP). Methods To analyze the therapeutic methods and prognosis of 56 patients with SAP. The patients were randomly divided into the conventional therapy group (A) and the intestinal barrier protection group (B). The APACHE Ⅱ score, Ranson score, Marshall score, CT severity index (CTSI), gastrointestinal functions score (GFS), the ratio of Lactulose to Mannitol (L/M), plasma Endotoxin and Diamine Oxidase (DAO), serum C-reactive protein (CRP) and TNF-α, incidence of pancreatic infection and multiorgan dysfunction syndrome (MODS), and the hospitalization mortality were compared between the two groups. Results On the 7th day after admission, the APACHE Ⅱ score, GFS, L/M, Endotoxin, DAO, CRP and TNF-α were significantly less in group B than in group A (P0. 05)between the two groups at 2nd week after admission. The incidence of pancreatic infection and MODS in group B were significantly lower than in group A (P0. 05) between the two groups. Conclusion Early intestinal barrier protection in SAP alleviated systemic inflammatory response, and reduced the incidences of pancreatic infection and MODS, thus improved the prognosis.
ABSTRACT
Objective To study the difference in outcomes between two treatment regimens of goal-directed fluid therapy in patients with severe acute pancreatitis. Methods From January 2000 to January 2010, 80 patients with severe acute pancreatitis were assigned into 2 groups. In group A,patients received fluid therapy aiming at the following goals in 24 hours: (1) Blood pressure >90/60 mm Hg;(2) CVP between 8-12 mm Hg;(3) Urine output >0. 5 ml · kg-1 · h-1. In group B, patients received fluid therapy aiming at the following goals in 6 hours (according to SSC guideline,2004): (1) mean arterial blood pressure >65 mm Hg;(2) CVP between 8-12 mm Hg;(3) Urine output >0. 5 ml · kg-1 · h-1 ;(4) central venous oxygen saturation >70%. After therapy for 3 days we measured the Marshall score, APACHE Ⅱ score, and the peri-pancreatic infection and mortality rates. Results The Marshall score was 6. 82±4. 69 and 4. 48±3. 78 in group A and B, respectively (P=0. 02). The APACHE Ⅱ score was 11. 35±5. 96 and 8. 22±4. 53 in group A and B, respectively (P=0. 01). The peri-pancreatic infection rate was 44% and 37% in group A and B, respectively, and there was no significant difference between the 2 groups (P = 0. 65). The mortality rate was 24% and 17% in group A and B. There was no significant difference between the 2 groups(P=0. 57). Conclusion Goal-directed fluid therapy in patients with severe acute pancreatitis according to the SSC guideline improved organ function but it did not reduce peri-pancreatic infection and mortality rates.
ABSTRACT
Objective To identify the risk factors and early indicators for misplacement of subclavian vein catheter into ipsilateral internal jugular vein.Methods From August 2008 to July 2009,subclavian vein catheterization was successfully performed with Seldinger method in 167 patients in Department of General Surgery,Xuanwu Hospital of Capital Medical University.The paraeentesis side,pameentesis site,direction of puncture needle.and the perceptions of both patients and operators during catheter placement were recorded.The correlation of these factors,age,and gender with the misplacement of subclavian vein catheter into internal jugular vein was analyzed.Results Sixteen patients(9.58%)experienced misplacement of subclavian vein catheter into ipsilateral internal jugnlar vein,which was not significantly correlated with age(P=0.375),gender(P=0.259),paraeentesis side (P=0.175),or paracentesis site(P=0.061).Misplacement of subclavian vein catheter into internal jugular vein was significantly more frequent when the direction of puncture needle was toward the midpoint of suprasternal fossa and laryngeal prominence(P=0.002).When the paracentesis site was located at a point at the junction of medial one-third and lateral two-tllirds of the clavicle.it was more frequent that the puncture needle was toward the midpoint of suprasternal fossa andlaryngeal prominence(P=0.010).There were more misplacement events when the patients feel ears pain(P=0.000)and when the operator felt resistance when inserting gnidewire during catheter placement(P=0.000).Conclusions Misplacement of subclavian vein catheter into ipsilateral internal jugnlar vein occurs more frequently when the direction of puncture needle is towards the midpoint between suprasternal fossa and laryngeal prominence.Patients feel ears pain and operators feel resistance when inserting guidewire during catheter placement are early indicators of misplacement.
ABSTRACT
Objective To evaluate the treatment methods of endophthalmitis after IOL implantation. Design Retrospective case series. Participants 15 patients with endophthalmitis after IOL implantation treated by Beijing Xuanwu Hospital in 2002-2008. Meth-ods Vancomycin was injected into vitreous cavity in all patients. Vitrectomy was performed on the patient whose infective bacteria could not be controlled by intravitreal injection. Main outcome measures Infective status, visual function, results of microbiological exami-nation. Result Endophthalmitis occured in 13 cases (86.6%) after 72 hours of cartaract surgery. Microbiological examination was per-formed on 15 cases (aqueous or vitreous sample), 6 cases showed positive results, in which 4 cases were staphylococcus epidermidis. The infection of 12 patients (80%) were controlled with intravitreal injection and 10 patients gained final visual acuity better than 0.1. Three patients received vitrectomy because infective bacteria can not be controlled. Conclusion Staphylococcus epi. may be the major cause of subacute endophthalmitis after cartaract surgery. Antibiotics injected immediately into vitreous cavity can control the infections in most cases.(Ophthalmol CHN, 2009, 18: 270-272)
ABSTRACT
Objective To investigate the safety,feasibility and effectiveness of early oral feeding after colorectal surgery. Methods A randomized controlled trial enrolled 47 patients undergoing elective open colorectal surgery from May 2007 to November 2007. The patients were randomized into group of early oral feeding (experimental group) or group of traditional oral feeding(control group). Postoperative course, gastrointestinal function, and complications were evaluated. Results No statistically significant differences were found in clinical characteristics including age, types of procedures, times of surgery or comorbidity between the two groups. There was no perioperative mortality in the two groups. Stoma1 leak occurred and progressed to abdominal abscess in one case in the control group. Passage of flatus and defecation after operation was earlier in experimental group than in control group(1.9 ± 0. 6 d vs. 2. 8 ± 0. 9 d,P <0. 01). Length of postoperative intravenous infusion was shorter in the experimental group (3. 8 ± 0. 9 d vs. 4. 8 ± 1.2 d,P < 0. 01). Length of postoperative stay was also shorter (9.0 ± 3.2 d vs. 10. 0 ± 3. 3 d, P = 0. 27) and the rate of abdominal distension was lower in experimental group(27% vs. 44%, P = 0. 23). The rate of nausea and vomiting was higher in the experimental group(31% vs. 20% ,P =0. 35), the differences were of no significance. Reinsertion of nasogastric tube due to nausea and vomiting and reoperation was necessary in 2 patients in the experimental group and control group respectively. There were 3 patients complaining fever postoperatively in the control group. Conclusions Early oral feeding after colorectal surgery is safe and feasible, and it can promote postoperative recovery effectively.

ABSTRACT
Objective Previous investigations suggest that severe acute pancreatitis (SAP) is one of the main causes of intra-ahdominal pressure (lAP) increase. The aims of this study were, to evaluate the increased IAP in patients with SAP and the correlation between LAP and severity or prognosis. Method Data of 75 SAP patients admitted to Xuan-Wu Hospital of Capital Medical University intensive care unit with SAP from January 2000 to Jan-uary 2008 were collected. All the patients had at least one organ dysfunction, and they were diagnozed with en-hanced CT, lAP were monitored in the 56 patients. The 56 patients were divided into three groups according to IAP, group A (7- 15 mmHg), group B (16-25 mmHg) and group C (26-31 mmHg). Maximal APECHE Ⅱscore, maximal Ranson score, maximal C-response protein (CRP), maximal arterial lactate, maximal creatinine, organ dysfunction, length of stay and mortality were compared. Results The 56 patients (24 male and 32 female)with average age of (52±14.1) years (ranging 21 - 72 years) and average body mass index (BMI) of 28±12.5(ranging 21 - 35) were monitored with IAP. The etiologic causes of SAP were biliary in 27 patients, alcohol in 14cases, hyperlipidemia in 11 cases and idiopathic in 4 cases. The rate of intra-abdominal hypertension was 89% (50/56), and 32% (18/56) patients complicated with abdominal compartment syndrome. There were 22, 26 and 8 patients in the A, B and C groups respectively. With the increasing of IAP, the maximal APACHE Ⅱ, maximal Ranson score, maximal CRP, maximal creatinine, organ dysfunction and mortality were also increased significant-ly. The mortality of the three groups was 13.6% (3/22), 23.1% (6/26) and 62.5% (5/8) respectively (χ2 =7.56, p = 0.023), and the total mortality of the 56 patients was 25%. The hospital stay of the three groups had no significant differenee(F = 2.23,P = 0.117). Conclusions IAP may be one of the markers used to evaluate the severity of SAP, and the monitoring of IAP is useful to assess the prognosis in patients with SAP.
ABSTRACT
Objective To study retrospectively the effects of low-dose glucocorticoids in outcomeof septic shock.Method The present stray was carried out by analysis of septic shock patients treated with norepinephrine or dopamine.A total of 46 patients with a confirmed diagnosis of septic shock admitted from January 2000 to October 2006 were divided into two groups:(1)ghcocorticoids treatment group(n=22),treated with glucocorticoids in addition to conventional treatment from November 2002 to October 2006;(2)conlrol group(n =24),only treated with routine treatment from January 2000 to October 2002.The differences in outcome were compared between the two groups.Results The duration of of vasopressor support was significantly shorter in treatment group com0~ed with control group.The percentage of shock reversal at 7 days was higher in treatment group than that in control group(72.73%vs.41.67%,P=0.034).Furthermore,a reduction in C-reactive protein(CRP)indicated inhibition of inflammatory response due to the effect of glucocorticoids in treatment group within 48-72 hours from admission to ICU(20.05±4.06 mg/dl vs.23.55±4.93 mg/dl,P=0.015).Therefore,APACHE Ⅱ score on 3rd day was significantly lower in treatment group than that in control group(16.76±4.87 vs.21.45±4.02,P=0.001).However,there were no statistical signifieances in the duration of mechanical ventilation,the length of ICU stay,the incidence of multiple organ dysfunction syndrome(MODS)and hospital-mortality between the two groups(P＞0.05).Conclusions Tmatmeut with low-dose gheocorticoids could effectively accelerate the recovery from refractory septic shock and the early withdrawal of vasopressor.It seems to be associated with the reduced production of CRP,suggesting the effects of low-dose glucocorticoids on both stabilization of hemodynamics and inhibition of inflammatory response.The beneficial effects of low-dose steroids regimens on long-term outconm of patients with septic shock have not determined.
ABSTRACT
Objective To summarize clinical characteristics and experiences in treatment of severe hyperlipidemic pancreatitis (SHLP). Methods A retrospective analysis for 22 cases of SHLP and 91 cases of severe acute biliary pancreatitis (SABP) hospitalized during January 1, 2000 to December 31, 2006 was carried out to compare their clinical characteristics and treatment outcomes. Results Activities of serum and urine amylase in SHLP patients at admission were (715 ± 99) and (382 ± 56) U/L, respectively, significantly lower than those in SABP patients (1551 ± 107) and (773 ± 66) U/L, respectively (P < 0.01). About 55% (12/22) of SHLP patients had pulmonary infection, 36% (8/22) with circulatory failure, 41% (9/22) with respiratory failure and 23 % (5/22) with renal failure, all significantly higher than those in SABP patients SABP [32% (29/91), 14% (13/91), 7% (6/91) and 5% (5/91), respectively, P < 0.01]. Two died of SHLP and 11 of SABP, respectively. Conclusions In diagnosis of SHLP, it should be noticed that no remarkable elevation of activities in serum and urine amylase usually, so during the course of treatment for SHLP, it is important to prevent and treat multi-organ failure, respiratory failure and renal failure in an active way.
ABSTRACT
Objective To study the antitumor effect of dendritic cell(DC) induced cytotoxic T lymphocyte (CTL). Method CTL induced by DC extracorporeally, were co-cultured with Bxpc-3 cells, CTL activity was observed by counting the killing of Bxpc-3 cells in vitro. Nude mice with Bxpc-3 cell transplant tumors were treated by injection of CTL on the edge of tumors, and kinetics of tumor growth was recorded, RT-PCR-ELISA was used to determine the telomerase of transplant tumor. Result CTL activity was 71.6%. Thirty-one days after transplantation tumor size and telomerase activity were not statistically different among therapy group and control group, whereas after fifty-five days tumor size (38?6)mm 2 , and telomerase activity (1.33?0.03) in CTL group were statistically different from that of ( 74? 33)mm 2 and (4.16?0.32) in control group. ConclusionDC induced CTLs suppress the experimental pancreatic tumor growth, providing an evidence for clinical immunotherapy of pancreatic cancer.
