The Present study designed according to AOAC is conducted to evaluate the practical protein quality of the porcine blood solely and mixed with other dietary proteins.Proximate analysis shows the average contents of crude protein and water in the spray-drying porcine blood are 85.0% and 12.0% respectively.The porcine blood protein is scant of Isoleucine (0.5%) and its Leu/Ile ratio is as high as 26. The amino acid pattern results in poor protein quality of the porcine blood, with BV, NPU and NPR value being only 16.5, 15.5 and 0 respectively. Therefore diets containing porcine blood as a sole source of protein can not maintain the normal body weight of rats.But porcine whole blood protein is rich in Lysine (7.8%) . When the spray-drying porcine blood is mixed with the wheat flour in proportion of 3%, the protein quality of the mixed dietary protein comparing with either of its constitutional proteins, is improved remarkably and its nutritive parameter values (BV:73.3, NPU: 61.8, PER: 2.46, Calbrated PER:1.9 and NPR: 4.3 respectively) are higher than those of the wheat flour protein (BV: 55.3, NPU: 46.6, PER: 1.01, Calibrated PER: 0.8 and NPR: 3.1 respectively).

Objective To detect the opening of the myocardial mitochondrial permeability transition pores (MPTP) after intrauterine asphyxia in neonatal rats,and to explore the mechanism of the myocardial hypoxic-ischemic and reperfusion injury caused by the opening of MPTP after asphyxia.Methods Cesarean sections were undertaken in female SD rats at the 21st day after pregnancy.The uterine arteries were clamped for 30 minutes followed by releasing for 1 hour and the pups were allocated into the asphyxia group.The uterine arteries were isolated but not clamped and the pups were allocated into the control group.There were 30 neonatal rats in either group and all of them were sacrificed 24 h after birth.Serum cardiac troponin Ⅰ (cTn Ⅰ) levels were detected by enzyme linked immunosorbent assay.The opening degree of MPTP was detected by fluorospectro-photometry.Myocardial ischemic areas were detected by TTC staining.Tissues from the cardiac apex were taken and the pathologic changes of the myocardium were explored by hematoxylin-eosin staining.SPSS for Windows 13.0 was used for statistic analyses.Results In HE staining slices,the myocardial cells in asphyxia group were disarranged and edematous.In control and asphyxia group,the serum cTn Ⅰ levels were (0.08 ±0.04) μg/L and (0.40 ±0.29) μg/L (P ＜0.01),the myocardial ischemic areas were (8.01 ±3.48) ％ and (42.50 ± 15.90)％ (P ＜0.01),and the opening degrees of MPTP were (118.10 ± 19.10) RFU and (79.40 ± 10.57) RFU (P ＜ 0.01) respectively.The serum levels of cTn Ⅰ,the myocardial ischemic areas,and the opening degrees of MPTP were significantly increased in asphyxia group compared with control group.The serum level of cTn Ⅰ was positive correlated with the opening degree of MPTP in either group(r =-0.384,P ＜ 0.01).Conclusion There are myocardial injuries in neonatal rats after asphyxia,which represent as high level of serum cTn Ⅰ,myocardial ischemia and necrosis.Opening of the myocardial MPTP is one of the causes of myocardial injury.

34 medical college students and 26 patients with primary hypertension were served as the subjects on low sodium salt diet for 4 weeks. Before and after the experiment, serum and urinary sodium and potassium, as well as blood presure, pulse rate, and body weight were measured. During the testing period, calorie and protein were supplied sufficiently and the salt content in their common diet taken was restricted strictly. The results showed that the serum sodium decreased, potassium increased at the end of the experiment, but the changes were all within the physiological permissible limits. On the contrary, urinary sodium increased, potassium decreased and the Na/K dropped markedly, body weight increased slightly in healthy subjects and decreased by 1.0-3.0kg in patients with hypertension. The blood pressure, both systolic and diastolic, was decreased but no change in the pulse rate was observed.It was obvious that in the subjects on common salt diet, the body sodium was high and potassium low, otherwise on low sodium salt diet, such situation might be improved, and the high blood pressure could also be ameliorated in the type Ⅰ and Ⅱ of hypertension.

AIM: To study the impacts of the myocardial connexin 43 degradation on conduction velocity during acute myocardial ischemia. METHODS: Studies were carried out in 16 dogs which were randomly divided into control group( n= 4) and ischemia group( n= 12). The acute myocardial ischemia was induced by ligation of the left anterior descending coronary artery. The conduction velocity of ischemic myocardium was determined. The content of Cx43 of the ischemic myocardium was examined by laser confocal microscopy with a double-label immunohistochemistry technique. RESULTS: (1)The Cx43 degraded rapidly during acute myocardial ischemia, and the conduction velocity of ischemic myocardium declined greatly; (2)The conduction velocity correlated positively with the Cx43 pixel density in each small region of ischemic myocardium; (3) The Cx43 pixel density decreased over 50% in the region which occuring permanent conduction block. CONCLUSION: These data suggest the degradation of Cx43 decreases the conduction velocity greatly during acute short time myocardial ischemia, and severe degradation of Cx43 would lead to permanent conduction block.

OBJECTIVE:To explore the method and approach for traditional Chinese pharmacists to play an active role in case of emergent epidemic situation.

RESULTS & CONCLUSION:In the differential treatment,pharmacists of traditional Chinese medicine should take full account of patients' individual differences,actively participate in the design of individualized dose scheme and offer medication guidance so as to enhance patients' medication compliance meanwhile enhancing the status of pharmacists of traditional Chinese medicine.

Objective To study the clinical use of the ulnar-basilic arteriovenous fistula as a long-term vascular access in patients with hemodialysis.Methods The clinical data of 36 patients with 1-year follow-up who had a wrist ulnar-basilic arteriovenous fistula formed in China-Japan Friendship Hospital from January 2013 and December 2014 were retrospectively analyzed.The outcomes for this study including the surgical results,complication rate of ulnar-basilic arteriovenous fistula,immediate patency rate,average maturation time,1-year primary patency rate and true patency rate were analyzed.Results Thirty-four cases patients got successful ulnar-basilic arteriovenous fistula formed with palpable vascular thrill.There were no death cases and no severe cardio-cerebrovascular complications.No infection,heart failure,distal swelling and ischemia occurred.The immediate patency of ulnar-basilic arteriovenous fistula was 94.4%(34/36),the average maturation time was (67±4) d,1-year primary patency rate was 63.9%(23/36),and true patency rate was 67.6%(24/36).Conclusion Ulnar-basilic arteriovenous fistula with adequate 1-year primary patency and low risk of infection and complications can be a viable alternative as the hemodialysis vascular access.

Objective To investigate the incidence,diagnosis,treatment and prognosis of abnormal lymphatic vessels in intestinal lymphangiectasia (IL) patients complicated by portal vein hypertension.Methods General information,clinical manifestations,laboratory tests,endoscopy and pathological examination,the results of direct and nuclide lymphangiography,treatment and prognosis of seven IL patients complicated by portal vein hypertension were retrospective analyzed.Results Among seven IL patients complicated by portal vein hypertension,there were five cases with abnormal lymphatic vessels and two cases were merely secondary to portal vein hypertension.The main symptoms were edema,abdominal distension and diarrhea.The results of laboratory tests mainly were lymphocytopenia (0.3× 109 to 1.7 × 109/L),hypoalbuminemia (16.0 to 27.8g/L) and hypoglobulinemia (13.2 to 17.7 g/L).Under endoscope,mucosal edema,chronic inflammatory reaction,intestinal villi spot and patched white nodular changes and polyp-like changes appeared.For treatment,the low-fat with medium-chain triglyceride diet and symptomatic support was the basic treatment.The condition could be relieved by surgical remission of abnormal lymphatic vessels or partial small-bowel resection.If the etiological factors could not be removed,the therapeutic effect was poor in the patients merely secondary to portal vein hypertension.Conclusion The suspicious IL patients complicated by portal vein hypertension need further examination to explore whether abnormal lymphatic vessels existed,and to provide evidence for surgical intervention.

Objective To summarize the clinical characteristics of liver cirrhosis complicated with chylous ascites.Methods From July,2007 to November,2012,patients diagnosed as liver cirrhosis complicated with chylous ascites were retrospectively analyzed.Analyze the etiology,liver function,ascites,imaging examination,treatment options and progonsis of these patients.Differences in measurement data were compared with U test.Results A total of 34 cases were enrolled,male 27 cases and female seven cases,average age (51.7±12.5) years old.Hepatitis B (20/34,58.8％) was the most common etiology of liver cirrhosis.Child-Pugh grading was grade B (26 cases) and C (eight cases).The appearance of aseites of 17 cases was chylous and the serm-ascites albumin gradient (SAAG) was 18.8 (2.6 to 32.5) g/L.The SAAG of 27 cases (84.4％) was no less than 11.0 g/L.The ascites triglyceride (TG) level was 2.94 (0.26 to 16.75) mmol/L,the TG of 27 cases (84.4％) was no less than 1.25 mmol/L.The level of TG (2.66(0.26 to 16.75) mmol/L) of patients with SAAG over 11.0 g/L was significantly lower than that of SAAG lower than 11 g/L (7.07(2.26 to 15.67) mmol/L,U=24.00,P=0.02).The lymphatic scintigraphy indicated that imaging agent leaked into peritoneal cavity in 29 cases (85.3 ％).Direct lymphangiography revealed lymphatic vessel structure abnormality in 15 cases (60 ％).Twelve patients received conservative treatment and four patients were effective,13 patients accepted peritoneal-venous shunting and 12 patients were effective,11 patients with microsurgical treatrnent and seven patients were effective.Conclusions Lymphatic struture is a possible cause of cirrhosis patients with chylous ascites.The characteristics of chylous ascites in cirrhosis patients are still the same as the characteristics of portal hypertension ascites.The SAAG remarkably increases,and the the level of SAAG probably depends on TG level.Lymphoscintigraphy has great value on the determination of the presence of ascites.And the direct lymphangiography could help to reveal lymphatic vessel structure abnormality.

Objective To compare the clinical results of endovenous laser treatment(EVLT),radiofrequency endovenous occlusion(RFO)and conventional stripping combined with transilluminated powered phlebectomy(TIPP)for lower extremity varicose vein.Methods From Jun 2004 to Jan 2007,200 cases(232 limbs)were treated by EVLT with TIPP,80 cases(88 limbs)by RFO with TIPP,and 180 cases(202 limbs)by conventional stripping with TIPP.Operation time,number of the incision made,intraoperative bleeding,postoperative hospital stay,complications,and one-year recurrence rate were compared with each other. Results Operation time was longer(41±8)min in RFO group than that in other two groups.Postoperative hospital stay was shorter in EVLT group(1.2±0.4 d)and RFO group (2.1±0.8 d)than that in stripping and TIPP group(P＜0.05).Patients in stripping group also suffered from more intra-operative bleeding more often incidental nervus saphenus injury and more incision numbers when compared with other two groups(P＜0.05).There was no significant difierence in one-year recurrence rate among patients in the three groups. Conclusions The clinical efficacy is almost the same among the three groups in terms of eradication of the varicose veins.EVLT and RFO are safe and minimal invasive for the treatment of lower extremity varicose vein.

Objective To study the clinical outcome of endoscopic vessel harvesting system (EVH) for the treatment of lower limbs varicose veins.Methods Patients (n =41) with varicose veins admitted from Jan 2011 to May 2013 were randomly divided into EVH group (n =20) and stripping group (n =21).Indexes as postoperative VAPS (48 hours and 1 week),subcutaneous ecchymosis (1 week),hematoma(1 week),skin numbness (1 week),CEAP classification (3 months),surgery effect and satisfaction scores(3 months) were compared between the two groups.Results 48 hours and 1 week VAPS was lower in EVH group(P ＜0.01).After EVH there was less subcutaneous ecchymosis (1 week),hematoma(1 week) and skin numbness (1 week) (all P ＜ 0.01).Postoperative CEAP classification improved significantly in both groups (P ＜ 0.01),while surgery effect and satisfaction scores (3 months) were better in EVH group (P ＜ 0.05).Conclusions EVH is a safe and minimally invasive technique in treatment of varicose veins of the lower limbs.
