Objective To evaluate the features of solid-pseudopapiHary tumors of pancreas (SPTP),and to compare with the clinical and pathological findings in order to improve the diagnostic accura-cy.Methods The CT appearances were analyzed retrospectively in 5 patients with pathologically proven SPTP.There were 4 women and 1 man,with the mean age of(16.20±7.49)years.Plain CT and contrasted CT were performed in all 5 cases.Results The tumors of 4 caseswerelocatedinthe head and neck of pan-creats and 1 case was in the body and tail of pancreas.Clear tumor margins were seen in all cases.The mean diameter of these tumors was 5.2 cm(3.0-9.0 cm).Two cases were predominantly composed of cystic por-tions,2 cases were mainly composed of solid portions,and 1 case was composed of similar proportions of solid and cystic portions.Inhomogeneous enhancement Was rewealed in contrasted CT scan,but Was lower in both phase than normal pancreas.Tumor border discontinuous ring-shape calcification was seen in 1 case,dilata-tion of the main pancreatic duct Was demonstrated in 1 case and no metastasis were seen.Conclusions Certain CT features may suggest the diagnosis of SPTP.CT combined with the clinical feature is helpful to the diagnosis.

Objective To investigate the etiopathogenesis of exertional heat stroke(EHS)induced by military training of those patients admitted in military hospitals,and analyze the influence of EHS as a predisposing factor on prognosis.Methods Eighteen patients with EHS were admitted in 6 military hospitals from Sep.1995 to Aug.2007,their clinical data were retrospectively analyzed.All cases were evaluated according to Minard's EHS predisposing factors including the individual's physiologic limitations,environmental conditions and the organizational predisposing factors.According to the final treatment outcome,18 cases of EHS were divided into fatal group(Group F)and survival group(Group S).The significance of deviation on the predisposing factors,and of the differences on the accumulated predisposing factors between the two groups,was analyzed.Results All the 18 cases of EHS occurred after military training,and complicated with multiple organ dysfunction syndrome(MODS).Hyposthenia,excessive physical efficiency training,incorrect disease classification to the patients,and inappropriate diagnosis and treatment were found to be the strong predictors to a grave prognosis.The effect of accumulated predisposing factors of EHS in group F was significantly higher than that in group S(10.0?1.41 vs 5.64?1.96,P

Recent years,progress has been made on the basic researches and clinical applications of ocular surface reconstruction with autologous or allogeneic limbal stem cells,oral mucosa epithelium and ex vivo cultured limbal stem cells.However,there are several issues,including the successful treatment for severe ocular damage,longterm follow-up and evaluation of clinical outcome,and the in vivo tracking of donor stem cells,remained to have definitive conclusions.Future studies should address the questions and challenges based on the basic research of limbal stem cell deficiency and standardized evaluation of clinical outcome.

Objective To study the experience of laparoscopic repair in gastric and duodenum perforation. Methods 35 patients with gastric and duodenum perforation were performed laparoscopic repair.Results 34 pati- ets with gastric and duodenum perforation were safely operated.1 case with perforation of gastric carcinoma was con- verted to open for radial gastrectomy.The mean time of hospitalization was 7.5 days.There was no intraoperative and postoperative complications.Pathological examination showed 4 patients with perforation of gastric ulcer and one with perforation of gastric carcinoma.Conclusion Laparoseopic repair was one of the safe,quick recovery and little suffering treatment for duodenum perforation.

Objective The prosthesis used for aortic valve replacement (AVR) can be too small in relation to body size,thus causing valve prosthesis-patient mismatch (PPM).The aim of this article was to summarize the preventive strategy of PPM during AVR.Methods A total of 357 patients [203 males,154 females; mean age (54.9 ± 18.7 ) years ] underwent AVR between February.2010 and December 2011.The weight and body surface area (BSA) of the group is( 60.1 ± 11.4 )kg and (1.67 ± 0.21 )m2 respectively.The aortic valve prosthesis effective orifice area (EOA) was divided by body surface area (BSA) to obtain the EOA index (EOAI).PPM was then defined as none or mild if EOAI was ＞ 0.85 cm2/m2,as moderate for (0.65 - 0.85 ) cm2/m2 and as severe for ＜ 0.65 cm2/m2.To avoid PPM,a simple three-step algorithm was applied:Step 1,Calculate the patient's BSA from weight and height;Step 2,Calculate the minimal valve EOA required based on the BSA to ensure an EOAI ＞0.85 cm2/m2 ; Step 3,Select the type and size of prosthesis that has reference values for EOA greater or equal to the minimal EOA value obtained in step 2.For patients with a small aortic root,the following three methods was used:( 1 ) Replace aortic valve with simple interrupted suture technique ; (2) Apply new type and high-performance prosthetic valves such as St.Jude Medical Regent mechanical valve ; (3) Enlarge the narrowed aortic root when necessary.Results Of all 357 patients,272 patients received mechanical AVR and 85 bioprosthetic AVR.Among the 49 patients who received AVR with simple interrupted suture technique.St.Jude Medical Regent mechanical valve was implanted in 38 patients and the aortic root enlargement was performed in 11 patients.The total prevalence of PPM was 6.4％ and there was no severe PPM.The prevalence of PPM with mechanical AVR and bioprosthetic AVR was 1.8％ and 21.2％ respectively.There were 4 deaths during early period of operation,and the operative mortality was 1.1％.Conclusion Prosthesis-patient mismatch can be effectively prevented at the time of AVR with appropriate measurement.

This study aimed to promote medical and health informationization construction, strengthen the top-level design, construct a standard of medical and health information, and develop an information sharing and safety management system. For the reform of integrated hospital and clinical information systems, the Tumor Research Institute of the Second Affiliated Hospital of the Third Military Medical University aimed to solve the existing problem using pain assessment management (PAM). The PAM information platform is affiliated with the Military's No. 1 Basic Information System, which can manage PAM information. Moreover, PAM can optimize the pain assessment process and costs, and improve the work efficiency of nurses, Thus, PAM can achieve basic goals, such as data sharing, individualized records, and smart reminders, and encourages the use of pain management information systems outside the hospitals.

Cardiac surgery carried out on cardiopulmonary bypass(CPB) in a pregnant woman is associated with poor neonatal outcomes although maternal outcomes are similar to cardiac surgery in non-pregnant women.Most adverse maternal and fetal outcomes from cardiac surgery during pregnancy are attributed to effects of CPB.The CPB is associated with utero-placental hypoperfusion due to a number of factors,which may translate into low fetal cardiac output,hypoxia and even death.Better maternal and fetal outcomes may be achieved by early pre-operative optimization of maternal cardiovascular status,use of perioperative fetal monitoring,optimization of CPB,delivery of a viable fetus before the operation and scheduling cardiac surgery on an elective basis during the second trimester.

Objective To prove that valve sparing aortic root reconstruction may have an impact on the outcome and longevity of the repair for patients with acute type A aortic dissection.Methods Clinical data of 98 consecutive AAAD patients undergoing the valve sparing aortic root reconstruction were analyzed.The postoperative follow-up and the clinical effect of the procedure were retrospectively analyzed.Results Pre-operative grade of aortic insufficiency was(2.3 ± 0.5), CPB-time was (217.8 ± 43.1)min, aortic cross clamp time was(142.7 ± 37.4)min and stay on ICU (11.1 ± 5.7) days, while hospitalisation was(14.3 ± 3.2) days.8 patients(8.2％) died peri-operatively.None of the early deaths were valve-related.Rethoracotomy rate was 3.1％.All patients followed up(19.3 ± 7.6) (6-68) months.Survival at 1 year was 90.8％.Freedom from valvular reoperation was 97.9％ at 3 years.At last investigation, mean grade of aortic insufficiency for AADA was 0.5 ± 0.3 (0-3).Conclusion Regardless of the underlying indication, the aortic valve preserving reimplantation technique can be performed with favourable functional results.
