After analyzing the clinical data of 5 injured persons diagnosed with delayed spleen or liver rupture combined with fractures after the Wenchuan earthquake, we found that the abdominal injuries in earthquake were rare but usually very severe. Since almost all the injured persons had multiple injuries, mortality was extremely high. First aid service should be applied in the first 6 to 8 hours. Orderly physical examination and peritoneocentesis in multiple sites are in favor of diagnosis. Reducing the missed diagnosis rate of abdominal injuries is important in raising the rate of successful treatment. Therapy for earthquake injuries should be focused on the most deadly injuries after a thorough examination, besides this, precise employment of control surgery, swift transportation of the injured persons, and prevention and dealing with complications are also important.

NF-κB a factor possessing multiple transcription functions, has been demonstrated to have relation with the imbalance between cell proliferation and apoptosis in stomach, intestines, liver and other tissues of digestive tract. The active NF-κB signal transduction is extensively involved in the precancerous lesion,rumor development and invasion and metastasis. The therapies aimed at the activation of NF-κB can promote apoptosis of tumor cells, reduce the resistance against chemo-radiotherapy and relieve the cachexia caused by tumor.

This paper presents a portable neurogenic bladder curer,which can produce a series of pulses according to human's physiology characteristic to stimulate bladder's points.Such bladder-related diseases can benefit from this curer as increased residual urine in the bladder,urine retention and urine incontinence.Being low-cost,small and portable,it can satisfy the needs of different patients.

Objective To explore the relationship between the retinal changes with pregnancy induced hypertension syndrome(PIH) and prognosis of maternity and fetus.Methods The fundus of 220 patients with moderate and severe PIH were examined and analyzed.Results All patients had fundus changes and the fundus changes were positively related with the degree of PIH(P

Multidrug resistant genes are highly expressed in hepatocellular carcinoma that seriousty affects the effect of chemotherapy. Screening of resistant genes from HCC cells and studying its mechanism of drug resistance will be helpful to improve the effecacy of chemotherapy for hepatocellular carcinoma. Here we described an alternative method called cyclical packaging rescue (CPR). First we constructed a retrovirus cDNA library of hepatoma cells and used it to infect fibroblasts. Then we added drugs to screen survival cells. The survival cells, stably integrated helper-free retroviral libraries, were recovered rapidly after transfection with plasmids expressing retroviral gag-pol and env genes. Through this method, retroviral RNAs were directly repackaged into new infectious virions. Recovered retroviral supernatant was then used to reinfect fresh target cells. When performed in concert with selection using functional assays, cDNAs regulating functional responses could be identified by enrichment through multiple rounds of retroviral library recovery and retransmission. Using CPR, we obtained several cDNAs. After a preliminary detection, we found Ribosomal protein S11 (RPS11), Ribosomal protein L6 (RPL6), Ribosomal protein L11 (RPL11), Ribosomal protein L24 (RPL24) possibly had drug resistant function.

The clinical data of 118 patients with bacterial liver abscess admitted to a tertiary hospital from January 2007 to December 2009 were analyzed retrospectively.Etiology study showed that 45.8％(54/118) cases of bacterial liver abscess were cryptogenic,40.7％ (48/118) were biliary source and 13.5％ (16/118) were hematogenous.The positive rate of pus culture was 57.1％ (36/63),among which klebsiella pneumoniae accounted for 72.2％ (26/36).The positive rate of blood culture was 31.2％(20/64) and klebsiella pneumoniae accounted for 95％ (19/20).One hundred and sixteen patients (98.3％) underwent color ultrasound examination with an accuracy rate of 93.2％.84 patients (71.2％)underwent the CT scan with an accuracy rate of 95.3％ and 20 patients underwent MRI with an accuracy rate of 85％.Seventy five patients (63.6％)accepted ultrasound-guided percutaneous aspiration and catheter drainage combined with antibiotic therapy; 40 patients(33.9％)were treated with antibiotics alone.On the discharge 27 patients(22.9％) achieved clinical cure,87 patients (73.7％) were classified as effective,4 patients (3.4％) had no effect and no death in this group of patients.The average length of hospital stay was 16 days.Cryptogenic was the most common cause of bacterial liver abscess,biliary source took the second place.Kleibsiella pneumoniae was the predominant organism.Detailed medical history inquiry,physical examination and assistant examination may increase the accuracy rate of diagnosis.Needle biopsy should be performed if necessary.Ultrasound-guided percutaneous aspiration and catheter drainage combined with antibiotics should be the first-line treatment.

With the development of imaging technique and molecular biological technique,researchers all over the world have made a great many of studies on the mechanism and treatment of lymphatic metastasis.The discovery of lymphatic endothelial cell-specific markers make it clear to distinguish lymphatic endotheliocyte.The application of new techniques such as immunohistochemical method and reverse transcription polymerase chain reaction (RT-PCR) can study the lymphatic metastasis from the genetic and molecular level.The application of molecular imaging and nanoparticles could provide new detection methods and therapies.The establishment of animal models offers a solid foundation for experimental study.

The viability of freeze-dried cells of Streptococcus thermophilus and Lactobacillus plantarum by adding different stabilizer and protectants such as skim milk, sucrose and trehalose were investigated. When the bacteria were dried with 150mmol/L trehalose,75% of S. thermophilus and 33% of L. plantarum cells were survived, comparing with control of 19% and 1% respectively. When S. thermophilus was exposed at 90℃, the cells with trehalose increased tolerance to high temperature. When S. thermophilus freeze-thawing for 4 and 8 cycles, the survival was much higher than that of without trehalose protected. Scanning Electro-microscope pictures showed that the cells with trehalose, appeared as normal, but those without the sugar were broken or collapsed. The data confirmed that the disaccharide could protect bacteria against stress conditions.

Total 118 patients with pyogenic liver abscess admitted to Zhongshan Hospital were classified into pypgenic liver abscesses of cryptogenic origin (PLAC,n =54),pyogenic liver abscesses of biliary origin (PLAB,n =48) and pyogenic liver abscesses of hemagenous origin (PLAH,n =16)according to the causes.The clinical features of three groups were compared and analyzed.The results showed that no statistically significant difference existed among three groups in clinical manifestation and signs.Compared to PLAB,the abscesses in right lobe of liver were more common in PLAC,diabetes mellitus was more prevalent in PLAC,but the co-existing diseases including chronic liver disease,non biliary malignant tumor and ALP elevation were less in PLAC.Klebsiella pneumoniae was frequently detected in PLAC,but there was no significant difference comparing to other two groups.No significant difference was found among three groups in the choice of therapeutic methods,the course of antibiotics,length of hospital stay and the days from admission to diagnosis.
