Objective To compare the differences between MELD and Child-Pugh grading in assessing of hepatic functional reserve in patients with cirrhosis,and analyse the correlation of two systems.Methods Retrospective analysis was made on 92 cases of hepatitis cirrhosis hospitalized with the MELD and Child-Pugh score by ROC curve,the difference and relation between two systems were compared.Results MELD and Child-Pugh system were significantly correlated(r=0.669,P < 0.000),3-month survival in patients with two systems ROC curve areas was significantly different(P < 0.05),while the MELD in patients survived more than 6 months was not significantly different compared with Child-Pugh(P>0.05).ConclusionMELD and Child-Pugh can accurately assess the prognosis of survival for patients with hepatic cirrhosis,and MELD is suitable for assessment of risk,heavy patients,not for those survived more than 6 months.

OBJECTIVETo report a case of simple congenital bilateral ejaculatory duct absence (EDA) complicated with seminal vesicle cyst and review the relevant literature in order to improve the diagnosis and treatment of the disease.

METHODSWe retrospectively reviewed the clinical data of a case of bilateral congenital EDA complicated with seminal vesicle cyst, reviewed the relevant literature at home and abroad, and comprehensively analyzed the embryonic development, diagnosis, and treatment of congenital EDA.

RESULTSThe patient was a 23-year-old man, present at the clinic for infertility after married for a year. Vasography and other imaging examinations confirmed simple congenital bilateral EDA complicated with seminal vesicle cyst. Pathologic biopsy showed normal spermatogenic function of the testes.

CONCLUSIONCongenital EDA originates from embryonic developmental defect of the mesonephric duct, and it can be confirmed by vasography. Transurethral incision of the ejaculatory duct and intracytoplasmic sperm injection can be employed for the treatment of bilateral EDA.

Oxidative stress-induced neuronal apoptosis plays a vital role in the development of neurodegenerative disorders;while at present its regulation pathways mainly include the NF-κB pathway;p53 pathway;MAPK path-way;PI3 K/Akt pathway;Nrf2 pathway;as well as other signaling pathways.Research findings suggest that the active components in Chinese materia medica exert significant biological activities in the treatment of oxidative stress-induced neuronal apoptosis.In the present paper;we review the recent research advances on the relative mechanisms of active components in Chinese materia medica against oxidative stress-induced neuronal apoptosis;so as to provide some references or clues for the clarification of possible mechanisms of active components in Chinese materia medica and the treatment of related neurodegenerative diseases.

Objective To investigate the application value of urine excrement shunt surgery for the treatment of severe metabolic disorders after Sigma rectum pouch of bladder cancer.Methods From July 2011 to December 2013,4 male patients (mean age 72±10 years old,ranged from 58-82 years old),who received radical cystectomy and Sigma rectum pouch due to bladder cancer,were admitted in our hospital.Within four years after the operation,all patients complained about the recurrent fatigue,anorexia and even unconsciousness.The hyperchloremic metabolic acidosis,hypokalemia and renal dysfunction were diagnosed by blood gas analysis and biochemical tests.One week before urine excrement shunt operation,the arterial blood pH,HCO3-,serum potassium,chloride and creatinine were (7.15±0.08),(7.8±4.7)mmol/L,(3.1 ±0.2) mmol/L,(110.3±4.7) mmol/L,(314.8±66.4) μmol/L,respectively.They received urine excrement shunt surgery.The lower abdominal mid-line incision was made and the pouch was isolated from intestinal tract.The abdomen ostomy was made and the sigmoid colon and rectum were re-coincided in order to recover the intestinal continuity.The results of blood gas analysis,electrolytes and renal function after surgery were compared with those before surgery.Results The average operation time was (256.3±26.9) min and the mean volume of bleeding was (147.5±111.2) ml.There was no surgery related complication.Blood bicarbonate was (19.1±4.8) mmol/L one week after surgery,which was significantly improved than that before operation (P＜0.05).One month later,blood pH level descended to (7.38±0.05),potassium level was (3.9±0.3) mmol/L,creatinine was (208.8±50.8) umol/L.All of them were significantly improved,compared with those results before surgery (P＜0.05).Blood chloride was significantly reduced to (102.4±5.8) mmol/L (P＜0.05) after 6 months of operation.Nobody developed severe acidosis and electrolyte disturbances during 6 months to 3 years' follow-up.Conclusions Urine excrement shunt surgery can effectively corrected the acidosis and electrolyte disturbances due to the radical cystectomy and Sigma rectum pouch.It might be a alternative method to treat such kind of severe complications.

Objective To discuss the causes of acute hematogenesis disorder after liver trans-plantation. Methods A retrospective analysis was performed to identify 6 patients with high fever,skin rash and acute haematogenesis disorder during 2005-2006 in our center. Results The 6 patients had viral infection, immunity damage, intake of marrow toxicity medicine and multiple organ dysfunc-tion syndrome after the operation. These might cause the disorder. Conclusion Infection, virus,drugs, graft versus host disease and immunity damage are the main reasons for acute hematogenesis disorder after liver transplantation.

Ligusticum Chuanxiong,a traditional Chinese medicine,has the functions of promoting Qi flow and blood,dispelling pathogenic wind and relieving pain.One of effective constituents extracting from Chuanxiong is tetramethylpyrazine,which has several pharmacological activities and anti-tumor function through inhibiting expression of vascular endothelial growth factor(VEGF).Recent relative studies provided scientific basis for a better application oftetramethylpyrazine clinically.

The pancreatic tissues from patients with islet cell hyperplasia,insulinoma,and pancreatic adenocarcinoma,as well as normal pancreatic tissues were embedded with paraffin,serial sections were cut and mounted on glass slides.Immunohistochemical staining was carried out with N-myc down-stream regulated gene 2 (Ndrg2) monoclonal antibody by means of ABC method,and Western blotting was carried out to detect the expression and distribution of Ndrg2.The results showed that Ndrg2 positive immunoreactivity was mainly localized in the cytoplasm of islet cell,being similar to the localization of insulin positive immunoreactivity.The number and volume of pancreatic islets were increased in the patients with islet cell hyperplasia,and Ndrg2 expression was also increased.Western blotting results showed that the expression of Ndrg2 in the pancreas of patients with islet cell hyperplasia was increased compared with normal group.The above results suggest that Ndrg2 may play an important role in performing physiological function of islet cells.

Objective To investigate the relationship between angiotensin Ⅱ ( AngⅡ) and transformation of vascular fibroblasts phenotype .Methods Eighteen rats were randomly assigned into the untreated group , mini-pump infusion of saline group and mini-pump infusion of AngⅡgroup which was used as the hypertension model .Their systolic pressure and vascular morphology were examined .The expression of catalase ( CAT ) and 4HNE was examined by immunohistochemistry .Western blotting was used to examine the expression of CAT of adventitial fibroblasts which were cultured by different incubation times and concentrations of Ang Ⅱ.Results Compared with untreated and mini-pump infusion of saline groups , the systolic pressure and carotid media thickness stained by HE of mini-pump infusion of AngⅡgroup were significantly higher (P<0.01).The results of immunohistochemistry showed that the expression of CAT ofAngⅡgroup was significantly lower than that of untreated group , however the expression of 4HNE of AngⅡgroupwas higher than that of untreated group (P<0.05).Furthermore, the results of Western blotting indicated that the effect of Ang Ⅱ on down-regulation of CAT function was in a dose and incubation time dependent manner .Conclusion AngⅡdown-regulates adventitial CAT expression and promotes fibroblasts phenotypic transformation which leads to pathological arterial vascular remodeling .

Objective To observe the change of brain iron content in deep gray nucleus using susceptibility weighted imaging (SWI) in patients with Parkinson's diseases (PD). Methods The SWI examination was performed in 40 PD patients (10 patients with Hoehn-Yahr stage Ⅰ , 9 patients with Hoehn-Yahr stage Ⅱ , 9 patients with Hoehn Yahr stage Ⅲ , 6 patients with Hoehn-Yahr stage Ⅳ, 6 ptients with Hoehn Yahr stage Ⅴ ) and 33 gender- and age- matched controls, after conventional brain magnetic resonance imaging examination on a 3.0T magnetic resonance imaging.The signal values of substantia nigra zona compacta (SNc), substantia nigra zona reticulate (SNr),red nucleus (RN), putamen (Pu), globus pallidus (GP) and caudate nucleus (CN) were assessed.Results Compared with the controls, the PD patients had statistically significance of signal value differences of SNc (P=0.002), SNr (P=0.043). RN (P= 0.003), Pu (P=0.023). GP (P=0.001) andCN (P=0.033). The more significant differences of SNc(P=0.001), SNr (P=0.010),RN (P＜0. 001 ), Pu (P=0. 008), GP (P＜0. 001) and CN (P=0. 011) were observed between more severe PD lesion and control. The signal values of SNc and GP showed obviously negative correlations with Hoehn-Yahr grading (SNcr=-0.943. P＜0.001; GPr=-0.923, P＜0.001). But there was weakly correlation of the signal values of SNr, RN, Pu, CN with Hoehn Yahr grading (SNr r=0. 496. P=0.001; RN r=-0. 480. P=0.002; Pu r=-0. 494, P=0.001; CN r=-0.471, P=0.002) Conclusions Measurement of the brain iron content of SNc and GP using SWI on MRI is a reliable means of diagnosing PD, and it has significant correlation with Hoehn-Yahr grading, It could evaluate the severity of PD.
