Objective To explore clinical characteristics and treatment for unexpected gallbladder carcinoma during laparoscopic surgery . Methods A retrospective analysis was made on clinical data of 12 cases of unexpected gallbladder carcinoma out of 4620 cases of laparoscopic cholecystectomy (LC) in our hospital from September 1997 to September 2015.Intraoperative frozen pathological diagnosis showed gallbladder cancer Nevin stage Ⅲin 1 case, and a conversion to open surgery of gallbladder cancer was conducted .The remaining 11 cases of gallbladder carcinoma were diagnosed by pathology after surgery .One case of Nevin stage Ⅰand 1 case of stage Ⅱwere not surgically treated .Of the other 9 cases of Nevin stage Ⅲ, there were 5 patients who refused surgery and 4 patients received open radical resection of gallbladder cancer at 10-18 d (mean, 14 d) postoperatively. Results The 5 cases of Nevin stage Ⅲwho refused open radical surgery were lost to follow-up.Two cases of stage Ⅰand Ⅱwere followed up for 63 months and 6 months after LC without recurrence .Of the 5 cases of stageⅢundergoing open radical surgery , 2 cases dead at 8 and 10 months postoperatively because of abdominal extensive metastasis and cachexia , and 3 cases dead at 10, 28, and 32 months postoperatively because of gallbladder carcinoma liver transfer . Conclusions The occurrence of unexpected gallbladder cancer should be taken into consideration during laparoscopic cholecystectomy .Timely and appropriate complementary therapy should be given .

Because the exact pathological mechanism underlying hypertrophic scars and keloids is unknown,there are a great number of treatment modalities, but it is unsatisfactory for the effect of treatment for the pathological scar.The vast array of treatment modalities for hypertrophic scars and keloids described by literature,whose treatmetn effects are varied and none of them is universally accepted in permanent hypertrophic scars and keloids ablation,are reviewed in this article in order to afford a reference for clinic medico.

Objective Rheological properties and gelation properties of agar were investigated. Methods The gelling point,melting point and the gel strength of agar were detected with MCR101 rheometer and TA texture testing instrument. Results and Conclusion Rheological properties of agar were affected by its concentration ,temperature and the addition of salt (such as NaCl ,CaCl2) and sucrose. Apparent viscosity exhibited shear thinning behavior following the power law model. Apparent viscosity increased with the increase of concentration,and decreased with the rise of temperature. The decrease in viscosity followed an Arrhenius temperature dependence. Agar solutions exhibited typical "weak gel" properties by small strain oscillatory measurements. The results indicated that the agar solution was characterized as a gel properties ,and which could form a kind of heat reversible gel. The gelling point of agar was lower than its melting point. The gel strength of agar could be affected by its gel time,and the addition of salt (such as NaCl,CaCl2) and sucrose.

By using the method of philology, 65 Hui prescriptions for treating cough were been collected to compare Arabic and Chinese names of pennisetum, anemarrhenae, honey, pease, white mustard, perilla and towel gourd stem. The Countif function in Microsoft Excel 2007 was used to count frequency of drugs in the prescriptions and summarize eight common Hui medicine for treating cough, namely sugar, honey, almond, fritillaria, liquorice, orange peel, white mulberry root-bark and lily. According to the commonly used drugs, philological studies and theories of Hui medicines, pathology and therapy of Hui medicines for treating cough were preliminarily inferred. In this study, 35 practical prescriptions and 30 simple and convenient Halal dietary prescriptions were summarized from collected prescriptions according to relevant literatures. On the basis of the long-lasting unique dietary therapy culture developed for Hui people, the simple and practical dietary prescriptions were defined according indications, therapy, prescription name and composition, and eight types of drug-admixed foods were summarized to relieve pains and improve health awareness and quality of life. Meanwhile, this study could also enrich and perfect the prescriptions, provide new ideas for improving health of patients, and lay a certain realistic foundation for further study of Hui medicines.

ObjectiveTo investigate the mechanism and the protective effect of heat shock protein 27 (HSP27) on rat cardiomyocytes when ischemic preconditioning performed.MethodsCultured rat cardiomyocytes were divided into four groups: control group, ischemic group,ischemic preconditioning group and cyclohexamide group. Cell viabilities were analyzed by MTT. The apoptosis was evaluated with DNA ladder and flow cytometry Annexin V Flous staining. Western Blot was used to determine the expression of HSP27 and caspase-3 in cardiomyocytes.ResultsIschemic preconditioning could improve cell viability. The apoptosis ratio in ischemic preconditioning group was significantly less than that in ischemic group. These were accompanied by an increase in the expression of HSP27 and a decrease in caspase-3. The expression of the increased HSP27 and the protective effect induced by ischemic preconditioning were completely abolished by the presence of cycloheximide, a translation inhibitor.ConclusionThe expression of HSP27 induced by ischemic preconditioning plays an important role in protecting cardiomyocytes, and the mechanism is possibly related to the inhibition of cell apoptosis.

Objective To investigate the value of measurement of cardiac output in children by bio-reactance versus echocardiography.Methods Pediatric patients admitted in pediatric department of Peking University First Hospital from September to December 2012 who needed hemodynamic monitoring were enrolled prospectively.Cardiac index(CI)and stroke volume(SV)were measured by echocardiography and non-invasive cardiac output measurement(NICOM)and compared by Spearman correlation and Bland-Alt-man analysis.Results Thirty patients were included.The median age was 7.25 years.CI[M(P5 ,P95 )] measured by NICOM and echocardiography were correlated significantly[3.42(2.28,4.92)L /(min?m2 ) vs.3.51 (2.94,4.85 )L/(min?m2 ),R =0.385,P =0.035 ].Bland-Altman analysis revealed a bias of-0.22 L/(min?m2 )(P =0.051 ),limits of agreement of -1.40 to 0.95 L/(min?m2 ).SV[M(P5 ,P95 )] measured by NICOM and echocardiography were correlated more significantly [36.3 (12.6,87.8 )ml vs.39.4(14.7,86.9)ml,R =0.768,P ﹤0.001 ].Bland-Altman analysis revealed a bias of -3.1 ml(P =0.176),limits of agreement of -27.4 to 21.2 ml.Conclusion There is no significant difference between NICOM and echocardiography for the measurement of CI and SV in pediatric patients.Further validation studies need to be conducted before routine clinical use.

Objective To evaluate the left ventricular diastolic function in coronary artery disease (CAD)patients without regional wall motion abnormality by real-time three-dimensional specke tracking imaging(RT3D-STI),and to investigate the value of RT3D-STI in detecting CAD.Methods According on coronary angiography,92 patients without regional wall motion abnormality were divided into two groups:control group(n = 21 ),without coronary artery stenosis;case group (n = 50 ),coronary stenosis group. Two dimensional images and the three-dimensional full volume dynamic images of left ventricle were collected.Routine parameters and end-systolic left ventricular globle longitudinal strain (GLS),globle circumferential strain (GCS),globle area strain (GAS),globle radial strain (GRS)and corresponding strain imaging diastolic index (SI-DI)were aquired,respectively.The parameters by RT3D-STI were analyzed to diagnose coronary artery stenosis.Results Compared with control group,there were no significant difference in routine parameters,GLS,GRS,GAS and GCS(P >0.05 ).Longitudinal SI-DI(L-SI-DI),area SI-DI(A-SI-DI),radial SI-DI (R-SI-DI),circumferential SI-DI (C-SI-DI)in case group were significantly reduced compared with control group (P <0.05).The sensitivity of L-SI-DI,A-SI-DI,R-SI-DI and C-SI-DI were 90.5%,81 .0%,85.7%,81 .0%,and the specificity of them were 82.0%,78.0%,68%,56%, respectively,L-SI-DI was the best in sensitivity and specificity.L-SI-DI,A-SI-DI,R-SI-DI were significantly correlated with Gensini score (r = -0.706,-0.547,-0.410 P < 0.05 ).Conclusions RT3D-STI can quantitatively assess the early changes of left ventricular diastolic function,which has important significance for early diagnosis of coronary artery stenosis.
