OBJECTIVETo explore the effect of Shenqi Fuzheng Injection (SFI) on gene expression profile of liver tissue with metastatic carcinoma in mice.

METHODSTwenty liver metastatic carcinoma model mice were established by splenectomy after their spleens were injected with 0.2 mL colon cancer C26 cell strain oncocyte liquid, then they were randomly divided into the model group and the SFI group. Starting from the 5th day after modeling, mice in the model group and the SFI group were given via intraperitoneal injection once every other day with physiological saline and SFI respectively. All the mice were sacrificed at the 15th day and the gene profile of metastatic liver carcinoma tissue in the two groups were screened by whole genome chip technique.

RESULTS(1) The model establishing successful rate reached 100%; (2) Gene expression showed that as compared with the model group, in the SFI group, 123 genes were up-regulated, with 52 of them registered to Ensemble, while only one gene was down-regulated and registered to Ensemble was none.

CONCLUSIONSFI plays its role of anti-tumor mainly by upregulating several relative genes to promote apoptosis of tumor cells and stabilizing chromosomes.

OBJECTIVE: To investigate the relationship between platelet activating factor (PAF) and occurrence of hepatorenal syndrome (HRS). METHODS: A total of 57 cases of patients with liver cirrhosis or hepatitis gravis were enrolled. The serum concentrations of PAF, lipopolysaccharide (LPS) and prothrombin activity (PTA), total bilirubin, and serum creatinine were detected in patients combined with HRS and in patients without HRS in hospital at the term. The correlations among the PAF, LPS, and the function of liver and kidney were analyzed. RESULTS: The concentrations of PAF and LPS in the patients combined with HRS were significantly higher than those patients without HRS. There were linear correlations between the PAF and LPS level, the total bilirubin level and PAF level, the PAF level and serum creatinine level. CONCLUSION The PAF associates with the occurrence of HRS. The PAF may mediate the occurrence of HRS induced by LPS. The PAF level may forecast whether patients with liver failure will take place HRS.

Objective To assess the effective length of jejunal graft when the 3~(rd) intestinal artery is u- tilized as vascular pedicle and afford a reliable theoretic base for clinical esophageal reconstruction.Methods In 32 formalin preserved and 21 fresh cadaver specimens,the diameter of 1st to 5th intestinal arteries and diameter of arterial arches are measured with linear calibre.Measure the length of jejunum that can be harves- ted as graft when the arches are extended.In the 21 fresh specimens,the 1st,2nd,4th and 5th intestinal ar- teries are ligated,acetic ester stained with red dye were injected into the lumen of 3rd intestinal artery via catheter.Extent of distribution of the arteries to the jejunum was observed.And then red ABS solution was in- jected into the 3rd intestinal artery to make into cast specimen.The blood supply distribution of jejunum through 3rd intestinal artery-arterial arch and communicating system were observed again.Results The di- ameter of the 3rd intestinal artery was the largest among the 1st to 5th intestinal arteries.The length of jejunum vascularized by 3rd intestinal artery can be as long as (142.2?62.3) (69.0～206.60cm) in acetic ester in- filtrated specimens.While in ABS east specimen,the average available extent of donor jejunum was(30.8?7.3) (23.0～37.3cm).Conclusion As observed by this applied anatomy study,the jejunum graft vascu- larized by 3rd intestinal artery alone has sufficient length to meet the need of esophageal reeonstrution.

OBJECTIVETo improve the diagnosis and treatment of testicular teratoma in children by analysis of clinical data.

METHODSWe retrospectively analyzed the clinical data about 64 cases of testicular teratoma treated in the Children's Hospital of Chongqing Medical University from 1995 to 2014.

RESULTSSixty-one of the cases presented painless scrotal mass with a sense of bearing down and the other 3 cases were confirmed because of empty scrotum diagnosed as cryptorchidism. The level of serum alpha fetal protein ( AFP) was obviously increased in 46 cases but normal in the other 18 preoperatively. Ultrasonography manifested abnormal inhomogeneous echo zones with calcification or necrosis. X-ray examination presented patchy or curvilinear high-density shadows in 28 cases. Forty-one of the patients underwent testis-sparing surgery (TSS) , 20 received high inguinal orchiectomy, and 3 refused surgical treatment. Pathological examination revealed 3 mature germinal layers in the 49 cases of mature teratoma and immature germinal tissue, including the original neural tube, and 11 cases of immature teratoma. The mature cases were exempted from chemotherapy, while the immature cases received the combination of cisplatin, etoposide, and bleomycin (PEB). The patients were followed up for 2 years postoperatively, which revealed no recurrence or metastasis.

CONCLUSIONMost children with testicular teratoma presented painless scrotal mass with a sense of bearing down and with abnormal serum AFP in most cases. Ultrasonography and plain radiography of the scrotum contribute to the diagnosis of the tumor. TSS is the main treatment option and intraoperative frozen-section can help the surgeons decide on the surgical mode. Postoperative chemotherapy is necessitated for immature teratoma but not for mature cases.

OBJECTIVETo investigate CT and MRI characteristics of primary spinal large B cell lymphoma.

METHODSCT and MRI data of 23 patients with primary spinal large B cell lymphoma confirmed by histopathology were retrospectively analyzed from March 2011 to August 2015. Among them, including 14 males and 9 females aged from 28 to 70 years old with an average of 53.4 years old. The clinical manifestation mainly focus on pain around spinal and minority peripheral nerve symptom. The courses of disease ranged from 2 weeks to 3 months with an average of 9 weeks. Nine patients underwent CT plain scan, 8 patients underwent plain and enhanced CT; 21 patients underwent MRI plain scan and enhanced; 15 patients underwent CT and MRI examination. The location, bone changes, shape, density, signal intensity and enhancement characteristics of lesions were observed and compared with pathology.

RESULTSLocation and size of lesion showed cervical vertebrae in 1 case, thoracic vertebrae in 16 cases, lumbar vertebrae in 2 cases, and sacral vertebrae in 4 cases. Mass was larger, the largest cross-sectional size of group was up to 73 mm× 125 mm. CT examination showed that 11 cases with "cloud and mist" shape change, 6 cases with compression fractures, and with "floating ice" shape change, 9 cases with "oversleeve" shape change, 11 cases with spinal stenosis; enhancement scan showed obvious reinforcement. MRI showed slightly low signal on T1WI and T2WI were slightly high signal, and signal was uneven, and enhancement scan showed obvious reinforcement, 13 of 16 cases with spinal canal stenosis changed like "oversleeve", intervertebral space showed no significant stenosis. Comparison of CT and MRI showed the manifestation of bone destruction by CT was superior than that of MRI, but the range of lesion, and related surrounding structures were not better than MRI. MRI displayed the range of lesion usually bigger than CT. Pathology results showed that 23 patients were all primary spinal large B cell lymphoma.

CONCLUSIONSPrimary spinal large B cell lymphoma has certain features in age, location and imaging findings. The "cloud and mist", "floating ice" and "oversleeve" shape bony destruction by CT and MRI has certain significance to diagnosis of primary spinal large B cell lymphoma.

Objective To investigate the relationship between the expression of matrix metalloproteinase-9 (MMP-9) and intercellular adhesion molecule-1 (ICAM-1) in the perihematomal tissues in human hypertensive,intracerebral hemorrhage (ICH) and brain edema formation following ICH.Methods Paraffin-embedded brain tissues of 39 human fatal cases of ICH from the perihematomal tissues,1—3 cm away from the margin of the hemorrhagic lesion,as well as tissues from the corresponding area at the opposite side as controls,were stained with HE and immunohistochemistry staining.The expressions of MMP-9 and ICAM-1 in the pefihematomal tissues were analyzed with the SPSS 11.5 system.Results ①With MMP-9 immunohistochemical staining positive capillaries in the perihematomal tissues were identified at 2 h ((1.2? 0.8)/HP).The number of MMP-9 positive capillaries began to rise at 5—10 h ((4.1?0.8)/HP) reaching the peak at 45—48 h ((10.6?1.4)/HP,P

OBJECTIVETo evaluate the efficacy and safety of tourniquet in total knee arthroplasty.

METHODStudies on comparison between with and without tourniquet in total knee arthroplasty were identified from Medline, PubMed, EMASE, Cochrane Library, CBM, Highwire, CNKI, VIP, Articles Digital Periodicals.All the randomized controlled trials were included for meta-analysis with RevMan 4.2.2 software.

RESULTSNineteen studies involving 15 in foreign languages, 4 in Chinese were identified. There were 1159 cases of knee replacement patients. The results of meta-analysis indicated that there were statistical difference between two groups on intraoperative blood loss (P = 0.000), the number of deep venous thrombosis (P = 0.020), thigh pain (P = 0.000), knee hematoma (P = 0.030), wound infection (P = 0.040), skin ecchymosis area (P = 0.000), and the increasing rate of knee circumference of 3 days after the operation (P = 0.000), while there were no statistical differences with respect to the total blood loss (P = 0.100), the number of blood transfusions (P = 0.150), operation time (P = 0.120), length of hospital stay (P = 0.350), the number of pulmonary embolism (P = 0.310), and skin blisters (P = 0.170).

CONCLUSIONSThe tourniquet for total knee arthroplasty can reduce intraoperative blood loss, but can not reduce total blood loss and the number of blood transfusions transfusion, can not improve operative efficiency, can not shorten the hospitalization time and promote the knee joint functional recovery. Furthermore the tourniquet increases the probability of occurrence on deep vein thrombosis, wound infection, hematoma and ecchymosis knee, it also causes knee swelling and thigh pain. It suggests minimize to use tourniquet in total knee arthroplasty.
