Traditional Chinese medicine (TCM), an important component of complementary and alternative medicine, has evolved over thousands of years with its own unique system of theories, diagnostics and therapies. TCM has been increasingly used in the last decades and become well known for its significant role in preventing and treating cancer. We believe that TCM possesses advantages over Western medicine in specific aspects at a certain stage of cancer treatment. Here we summarize the advantages of TCM from three aspects: preventing tumorigenesis; attenuating toxicity and enhancing the treatment effect; and reducing tumor recurrence and metastasis.

To develop an effective therapeutic HBV DNA vaccine, two eukaryotic expressing plasmids, namely pcDNAS 2 ?S and pcDNAIIF , which respectively encoding HBV middle envelope protein preS 2 ?S and human IL 2/IFN ? fusion protein, were constructed by DNA recombinant technique. After identification by restriction analysis and DNA sequencing, the constructed recombinant plasmids were transfected into COS 7 cells in vitro with transfection reagent Lipofectamine. The expressed product in supernatant was quantified by ELISA , and the biologic activities of IL 2 and IFN ? were assayed by CTLL 2 cell line proliferation and cytopathogenic inhibition, respectively. The results showed that secretive expression of preS 2 ?S and hIL 2/hIFN ? fusion protein peaked at 48h after transfection, and the expression levels were HBsAg(P/N)=7 63, IL 2=10 35ng/ml, and IFN ?=7 90ng/ml. The IL 2 and IFN ? activities in the culture supernatant of COS 7 cells transfected with pcDNAIIF were 998U/ml and 249U/ml, respectively. These results suggested that the recombinant plasmids pcDNAS 2 ?S and pcDNAIIF were correctly constructed and the transfected cells could express secretive active protein.

As the development of hospital information systems in the third-tier hospitals of the first grade in China gradually deepens, there has appeared an urgent need to formulate standards for the management of such systems. The paper offers proposals for the structure, composition and main responsibilities of the centers for hospital information management, posts setting and post responsibilities in the centers, the number of allocated personnel in the centers and the number of personnel required for various posts, and management standards and operating procedures in the centers.

BACKGROUND:Femoral shaft fracture is common in children Various methods of treatment can be used successfully,depending On the age of the child and the type of fracture.OBJECTIVE:To evaluate the feasibility of adult reconstruction plate of humeral shaft for pediatric femoral shaft fracture.METHODS:A total of 32 children with femoral shaft fracture were treated with adult reconstruction plate of humeral shaft in First Department of Orthopedics,Fuzhou General Hospital of Fujian Medical University,including 20 males and 12 females aged 6.7years(5-8 years).All patients were treated with incision reduction and adult reconstruction plate of humeral shaft.The incision length should be made as short as possible according to the fracture type The result of surgery was determined using clinical and radiographic examinations The pain condition was evaluated using visual analog scale method before and 3 days following surgery.RESULTS AND CONCLUSION:The patients were followed up for 1-2 years(average 1.5 years).All fractures were healed 1-2months postoperatively,and the internal fixator was removed 4-8 months postoperatively.The affected limb was shortened0.6-1.5 cm(average 1.1 cm)in 3 cases.Overgrowth was obsewed in the other patients by 0.3-1.2 cm The average overgrowth length was(0.64±0.312)cm in 29 patients.At 3 days postoperatiVely,the mean subjective pain was significantly reduced,and range of motion was improved compared with the day before surgery There was no infection or implant displacement or re-fracture.It is feasible to use adult reconstruction plate of humeral shaft for paediatric femoral shaft fracture.

ObjectiveTo examine the effects of temsirolimus, an inhibitor of mammalian target of rapamycin, on bladder cancer cell lines T24 and BIU-87 in vitro and in vivo for purpose of evaluating the probability of mTOR targeted therapy for bladder cancer.MethodsAfter being treated by a different concentration of temsirolimus, T24 and BIU-87 cells were tested by MTT assay for cell proliferation activity.Cell cycle and apoptosis analysis were performed with flow cytometer. Wound scratch assay was used for cell migration activity and transwell motility assay. Western blot analysis was used to test the mTOR phosphorylation. Subcutaneous inoculation of 6-week-old nude mice was performed using 1 × 106 T24 cells in 50％ matrigel for both control (n = 10) and temsirolimus (n = 10) groups. The volume of tumors was examined and then the expression of Ki-67 was detected by immunohistochemistry.ResultsTemsirolimus significantly inhibited proliferation of T24 and BIU-87 cells in a dose- and time-dependent manner. After administration of temsirolimus on T24 and BIU-87 cell lines for 24 h, the rate of wound healing in 0 nmol/L groups were (88.9 ± 14. 1 ) ％ and ( 83.6 ± 16.3)％ , which were higher than in the 5 nmol/L groups, which were (42.7 ± 11.6) ％ and ( 36.9 ± 9.7 ) ％ ( P ＜ 0.05 ). In the transwell motility assay, the number of cells in the 0 nmol/L group was 26.5 ± 5.8 and 28.2 ± 4.6, which was higher than in the 5 nmol/L group ( 19.0 ±3. 8 and 21.3 ± 5.1, respectively) (P ＜ 0. 05). When temsirolimus was administered on T24 and BIU-87 cell lines for 48 h the percentages of cells delayed in phase G0/G1 in 5 nmol/L group were ( 77.46 ±6.11)％ and (73. 39 ± 4. 94)％ respectively, and higher than in the 0 nmol/L group, which were (65.99 ±5.01 )％ 、(60.15 ±3.98)％ (P ＜0.05). There was no statistically significant difference in the apoptosis rate between the two groups (P ＞ 0.05 ). In Western blot analysis, the ratios of p-mTOR/β-actin were 0.92 ±0.09 and 1.01 ± 0.08 in 0 nmol/L group, and higher than in the 5 nmol/L group (0.47 ±0.05、0.04 ±0. 01 ) (P ＜ 0.05 ). After administration of temsirolimus for 21 days, the tumor volume in nude mice in the control group were 351.1 ± 139.9 mm3 , which was larger than 351.1 ± 139.9 mm3 in the temsirolimus group ( P ＜ 0.05 ). The positive rate of Ki-67 expression was ( 67.3 ± 8.4 ) ％ in the control group, which was higher than in the temsirolimus group ( 35.5 ± 6.7 ) ％ ( P ＜ 0.05 ).ConclusionsThis study provides in vitro and in vivo evidence that temsirolimus may inhibit the viability of bladder cancer cells and temsirolimus could be exploited as a potential therapeutic strategy in bladder cancer.

Acute obstructive suppurative cholangitis (AOSC) is one of the most serious acute abdomen.The incidence of abdominal infection is significantly improved when patients were complicated with AOSC and diabetes mellitus,and then bile leakage,intestinal fistula and even death were induced by abdominal infection.The management of abdominal infection is very important for the prognosis of patients.One patient with AOSC and diabetes mellitus was admitted to the No.425 Hospital of PLA from May to July in 2013.Recurrent abdominal infection and abscess occurred after the operation due to his family members' refusal of surgery at early period and lax control of blood glucose before and after surgery,and then bile leakage and intestinal fistula were induced.The patient underwent operation for 3 times,and was cured after receiving fasting,gastrointestinal decompression,parental nutrition,somatostatin administration and antibiotic treatment.

Neuron is the basic unit of the biological neural system. The Hodgkin-Huxley (HH) model is one of the most realistic neuron models on the electrophysiological characteristic description of neuron. Hardware implementation of neuron could provide new research ideas to clinical treatment of spinal cord injury, bionics and artificial intelligence. Based on the HH model neuron and the DSP Builder technology, in the present study, a single HH model neuron hardware implementation was completed in Field Programmable Gate Array (FPGA). The neuron implemented in FPGA was stimulated by different types of current, the action potential response characteristics were analyzed, and the correlation coefficient between numerical simulation result and hardware implementation result were calculated. The results showed that neuronal action potential response of FPGA was highly consistent with numerical simulation result. This work lays the foundation for hardware implementation of neural network.
