Objective To study the effect of the products of entermorpha (EP), chlorella growth factor (CGF) and entermorpha dietary fiber (EPDF) on defecation and blood lipid regulation. Method Based on the composition of EP products, the male ICR mice were intervened with EP, EPDF and CGF with three doses. Using the constipation model induced by compound diphenoxylate, the effect of EP products on enterocinesia function of mice was determined by measuring defecation and the percentage of ink-pushing in small intestine. High-lipid rat model was established by feading high fat diet and the intervention effect with three doses of EPDF and CGF for 6 w was observed. Results As compared to the model group,all doses of EP,both middle and high doses of EPDF,and high dose of CGF could shorten the time of first defecation and increase the percentage of ink-pushing in small intestine of costive mice (P

The viable but noncuturable (VBNC) state is a survival strategy when bacteria are exposed to en- vironment stress. The VBNC state is part of the life cycle of non-differentiating bacteria, and it has a far-reaching impact on traditional bacteriology. Cells in the VBNC state fail to grow on the routine bacterio- logical media, here its significance in human health and environment science are detailed. Cells entering the VBNC state exhibit dwarfing and a number of metabolic changes in respiration rates and macromolecular synthesis. This paper summarized the variations in DNA and protein comparing to the culturable cells. We also discussed the ability of cells to resuscitate from the VBNC state and return to an actively metabolizing and culturable form. Some new methods for monitoring the VBNC state were listed. Finally the future was suggested.

Objective To analyze the relationship between needs of assistive devices and the three other factors (age, disability categories, severity levels of disability) in order to scientifically formulate subsidy policy on assistive devices.MethodsThe assessment of rehabilitation needs for 928 Shenzhen citizens with new disability certificates in its six districts was performed by professionals, and the data was recorded into ACCESS database and analyzed.ResultsThe sequence of demand rates on assistive devices among disability categories was vision disability (78%), hearing disability (76%) and physical disability (74%); but speech, mental retardation and psychological disabilities had a low demand. The demand rates of assistive devices were dissimilar among four age groups for persons with vision, hearing and physical disabilities; for severity levels of three disability categories of vision, hearing and physical disabilities: the milder the vision disability was, the greater demand rates of assistive devices were; the demand rate of those with the second level of hearing disability was the highest; the demand rates of persons with the first and second levels of physical disability were relatively higher.ConclusionWhen drawing up subsidy policy on assistive devices for persons with disability, the disability categories, ages of persons with disability and severity levels of disability should be considered; the different types of assistive devices should be supplied according to rehabilitation goals at different age group; and necessary assistive devices should be provided according to severity levels of disability.

OBJECTIVETo study the predicting effect of proly 4-hydroxylase beta polypeptide (P4HB) in treating non-small cell lung cancer (NSCLC) patients by Yiqi Chutan Recipe (YCR).
METHODSTotally 46 stage III and IV NSCLC patients were treated by YCR for 4 therapeutic courses. Effect was assessed by RECIST of solid tumor. P4HB expression was detected in the lung cancer tissue by immunohistochemical assay. Factors affecting disease control rates (DCR) of YCR were analyzed by Logistic regression analysis. The correlation between P4HB expression and the effect of YCR was analyzed.
RESULTSThe DCR of advanced NSCLC treated by YCR was 36.96% (17/46 cases). P4HB was high expressed in advanced lung cancer tissue (6/15 cases). Gender, initial treatment, and retreatment are independent factors for affecting DCR of treating lung cancer by YCR.
CONCLUSIONP4HB might be taken as a factor for predicting the effect of YCR in treating NSCLC.

Objective To investigate the clinical outcomes of sternoclavicular hook plate in treatment of the anterior sternoclavicular joint dislocation. Methods A new device named sternoclavicular hook plate was devised by our team. Between May 2002 and Octorber 2009, 66 patients with sternoclavicular joint anterior dislocation were treated with the new device, among whom there were 47 males and 19 females,aged 21-68 years old (average, 32.6 years old). Twenty-one cases were caused by crush injury, 5 cases by falling and 40 cases by traffic accident. Anterior fracture-dislocation was found in 41 cases. According to the Allman system, there were 35 cases of type Ⅱ and 31 cases of type Ⅲ. Patients were evaluated with serial clinical and radiographic examinations. Rockwood score were used after the operation to assess the curative effect. Results The average operative time was 33 min (range, 20-48 min). The mean blood loss was 60 ml (range, 20-90 ml). There were no vascular or peripheral nerve injuries in the patients. All incisions healed smoothly. The X-ray and CT showed that the reduction of sternoclavicular joint and the location of internal fixation were satisfactory. All the 66 patients were followed up for 12-37 months (average, 17 months). There was no internal fixation failure, redislocation or other complications. The sternoclavicular hook plate was removed 12 months after operation. The mean Rockwood's score was 13.2 (8 to 15). There were excellent in 50cases, good in 15 cases, and fair in 1 case. Conclusion The sternoclavicular hook plate is a new, safe and liable technique for sternoclavicular fracture-dislocation. This new technique is helpful for early functional exercises.
