Objective To study a new method for internal drainage and primary suture after laparoscopic choledocholithotomy (LCH). Methods Twenty-five patients with chronic cholecystitis combined with cholecystolithiasis and choledocholithiasis were performed laparoscopic cholecystectomy and choledocholithotomy and extraction of stones with choledoscopy. Results One case of Mirizzi' syndrome converted into laporotomy and 24 cases were successfully performed. Excluding neither internal nor external drainage was carried out with primary closure of common bile duct (CBD) in 1 case and T-tube were placed in 4 cases, the made-self 3mm～5mm diameter silica tubes with one-way hook were placed into the common bile duct for internally drainage in 19 cases. The time of operation was from 90 to 420 minutes with a mean of 145 minutes. 1～5 calculus were removed from CBD. A mean of hospitalized days stay was 7.5 day. Conclusions The operation of internal-tube drainage of LCH frees either the inevitably risk of hyper pressure of biliary duct because of the spasm of Oddi's sphincter or disadvantage of T-tube for drainage after LCH, which is new method both safety and practicality, both simpleness and easiness, and accords with the physiological needs of the human body.

Objective To investigate the feasibility and techniques of laparoscopic biliary re-operations. Methods Laparoscopic surgery was performed in 13 patients with bile duct stones who already had undergone biliary tract operations. Results Laparoscopic choledochotomy was successfully completed in 12 cases, while a conversion to open surgery was required in 1 case. The success rate of laparoscopic surgery was 92.3% (12/13).

BACKGROUND:Bone marrow mesenchymal stem cells have beneficial effects on the treatment of various diseases. Mitochondria transfer is newly proposed and its specific mechanisms of action and control factors remain unclear.
OBJECTIVE:To review the studies about stem cells and mitochondrial transfer, then to discuss its value on clinical.
METHODS:The PubMed, VIP and Wanfang databases were searched for related articles concerning stem cells and mitochondrial transfer. Key words were“stem cell, embryonic stem cell, progenitor cell, mitochondria”in Chinese and“Stem cell[s], Mother cell[s], Progenitor cell[s], Colony-Forming Unit[s], Colony Forming Unit[s], Mitochondria[l] transfer”in English. Thirteen articles were found initial y, and using the citation tracking method, final y 42 articles were determined. RESULTS AND CONCLUSION:Studies have shown that mitochondrial transfer from bone marrow mesenchymal stem cells is associated with rescue of aerobic respiration and restoration of mitochondrial function in the injured somatic cells. Bone marrow mesenchymal stem cells and recipient cells form tunneling nanotubes for mitochondrial transfer. Movement of mitochondria between cells is regulated and directed by Miro1. The successful transfer of mitochondria may be accompanied with the clearance of damaged mitochondria. The rescue of mitochondrial function in early stages may provide a valuable therapeutic strategy for various diseases include acute lung injury.

This study developed a novel approach of targeting malignant glioma with pMAGE-A1(278-286)-specific cytotoxic T lymphocytes (CTLs) induced from the peripheral blood mononuclear cells of healthy donors by multiple stimulations with human leukocyte antigen (HLA)-A2-restricted pMAGE-A1(278-286) peptide-pulsed dentritic cells. Cytotoxic assays were performed by the colorimetric CytoTox 96 assay to analyze cytotoxic activity of the induced CTLs against various target cells. The induced CTLs showed approximately 45% specific lysis against T2pMAGE-A1(278-286) (pMAGE-A1(278-286) peptide pulsed T2 cells) and U251 (HLA-A2(+), MAGE-A1(+)) at an effector:target ratio of 40:1, and approximately 5% cytolysis against T2pHIV, A172 (HLA-A2(-), MAGE-A1(+)), K562 and T2 cells without being pulsed with peptide at any effector:target ratio. The specific killing activity of the induced CTLs against T2pMAGE-A1(278-286) and U251 was much more obvious than in any other control group (P<0.05). The cytotoxic activity against the T2pMAGE-A1(278-286) and U251 was significantly eliminated by anti-HLA class I mAb W6/32. These results suggest that pMAGE-A1(278-286) epitope may serve as a surrogate tumor antigen target of specific immunotherapy for treating HLA-A2 patients with malignant glioma.

Objective To explore the preventive and therapeutic effects of diminazene (DIZE) on pulmonary arterial hypertension (PAH) in rats.Methods Left pulmonary lobectomy combined with injection of monocrotaline was used to establish a rat model of pulmonary arterial hypertension.One hundred adult male Wistar rats were randomly divided into blank control group (group A,n=20),DIZE control group (group B,n=20),PAH model group (group C,n=20),PAH model plus DIZE group (group D,n=20) and PAH model plus DIZE and C-16 group (group E,n=20).Angiotensin-converting enzyme 2 (ACE2),IL-6 and IL-8 levels were determined by fluorescence resonance energy transfer (FRET) and enzyme linked immunosorbent assay (ELISA),and the mean pulmonary arterial pressure (mPAP) and right ventricular hypertrophy index (RVHI) were measured.The wall thickness (WT) and intimal hyperplasia score were calculated,and the pulmonary vascular lesions were analyzed using elastic fiber staining.Results RVHI,ACE2 enzyme activity and WT in the group A were significantly different from those of the groups C,D and E (P<0.05).Those of the group D and E were significantly different (P<0.05).The five groups showed significant differences in the overall analysis of each index (P<0.05).Conclusions Diminazene can increase the ACE2 enzyme activity,and decrease the mPAP,RVHI and WT,while reducing the pulmonary arterial medial hypertrophy,and inhibit intimal hyperplasia of pulmonary arterioles.The results of this study provide an experimental basis for the use of diminazene in the treatment of human pulmonary hypertension.

Objective: To study the effect of Shenxiong Xintong Pill(SXP) on cardiac hemodynamics. Methods: Parameters of cardiac hemodynamics were examined in anesthetic chest-opened dogs medicated with various doses of SXP. Results: After intraduodenal administration of SXP of 2.0g/kg, the coronary blood flow was raised, coronary resistance decreased, heart rate slowed and the left ventricular diastolic end pressure fallen in the dogs. No obvious changes were found in the contraction , works and ejection of left ventricle. Conclusion: The mechanism of SXP in relieving angina pectoris was probably related to the dilatation of coronary artery and increase of coronary flow with the increase supply of oxygen.
