As to evaluating the medical compliance of patients with chronic hepatitis B (CHB) and the influence factors, information of 163 patients with CHB treated with lamivudine were collected by using the self-designed questionnaire, and the medical compliance and influencing factors of the patients were acquired by the research followed, and the prognosis and allocation were also observed. The results showed the medical compliance in 77.3% of patients with CHB was good, and in 22.7% patients was poor. After following-up for 2 years, the negative rates of HBV DNA and HBeAg shown in patients with good medical compliance were 78.6% and 46.0%, respectively,showing a significantly higher rate than in those with poor medical compliance, which having the rate of 37.8% and 21.6%, respectively (P<0.01). We suggested that there should be a correlation between the medical compliance of patients with CHB and the prognosis.

Objective Objective To study the feasibility of direct applying MRI to TPS by measuring the geometric distortion of MRI. Methods Phantom 1 was made by marking radical arrangement of fat pipelines every 15? in foam phantom and Phantom 2 by net arrangement at every 2.7?cm. Coronal and transverse scan parallel with the radial and net fat pipeline in the phantom was performed at sequence of cranial FSE T2WI by Marconi 1.5T superconduct MRI machine. Geometric distortion in 5 different fields of view (FOV) was calculated by measuring the absolute borderline error of direct scan and coronal digital reconstructed radiograph (DRR). Results When FOV was equal or smaller than 11.0?cm?11.0?cm, 22.0?cm?22.0?cm and 27.5?cm?27.5?cm, the geometric distortion was 0.0, 1.1 and 1.4?mm of direct scanning MRI and 1.0,1.4 and 2.0?mm of coronal DRR. Conclusion When the magnetic field of MR is high and the tissue shows uniform density, MRI can be applied on TPS directly.

Objective To investigate the clinical efficacy and safety of ziprasidone mesylate injection on the acute agitation symptom in mental retardation. Methods The total of 80 patients of mental retardation with acute agitation symptoms were randomly divided into two groups:the treatment group (40 patients) were intra-muscarly given with ziprasidone mesylate injection at the initial dose of 10 mg, 20 mg 4 h later, and 30 mg once on the second day and third day. And the control group (40 patients) were treated with haloperidol injection. The volume dose of haloperidol was 20 mg everyday. Other antipsychotic drugs, antimanic drugs and benzodiazepines were not allowed to be used during the observation, neither does the prophylactic use of drugs against parkinson's disease. Before and 1, 2, 4, 6, 8, 12, 24, 48, 72 h after treatment, the positive and negative scale ( PANSS) reduction rate, the end of the clinical global impression scale ( CGI) were assessed. By the end of the treatment, the adverse reactions symptom, cale ( TESS) was assessed for the safety. Results By the end of treatment PANSS reduction rate was 46. 31% in the test group and 48. 81% in the control group, the clinical improvement rate was 80. 00% in the treatment group and 82. 50% in the control group. No statistically significant difference on efficacy was found between two groups. The side reaction rate in the treatment group was 27. 5%, that in the control group was 40. 0%, there was significant difference ( P<0. 05) between two groups, but the extrapyramidal reaction in the control group was significantly more than that in the treatment group(P<0. 05). Conclusion Ziprasidone mesylate injection is effective on treating the symptoms of mental retardation, in corresponding to the effect of haloperidol injection,and with less extrapyramidal reactions.
5.Relationship of intestinal microecology with infantile cholestatic liver disease
Journal of Clinical Hepatology 2015;31(8):1221-1225
Intestinal microecology is an important and complex biological system essential to human health. Intestinal microecology and the liver are closely related in anatomical structure and function. Infantile cholestatic liver disease lead to abnormal bile secretion, abnormal excretion, and reduced bile release into the intestinal tract. As a result, the intestinal mucosa barrier is damaged and intestinal microecology changes; at the same time, pathogenic bacteria and endotoxin translocation cause liver injury and aggravate cholestasis. Therefore, a close relationship of intestinal microecology with infantile cholestatic liver disease can be found. In this article, the relationship of intestinal microecology with the development and progression of infantile cholestatic liver disease is illustrated and it is concluded that probiotics should be given as a supplement when infantile cholestatic liver disease occurs, because it promotes bile secretion, blocks intestinal inflammatory reactions, and improves prognosis of the disease. It is recommended to provide microecological agents routinely as a method to prevent and treat infantile cholestatic liver disease.

OBJECTIVETo investigate the insulin-like growth factor-I (IGF-I) gene and polypeptide expression in cultured rat osteoblast (ROB) and the role of IGF-I in mediating the cell-to-cell communication by mimicking the pharmacokinetics of parathyroid hormone (PTH).
METHODSThe ROB was cultured with three kinds of treatment: (1) Control (Ctr), the cells were cultured without PTH during the first 6 hours and the subsequent 42 hours in a 48-hour cycle; (2) Intermittent exposure to PTH (Itm), the cells were cultured with PTH during the first 6 hours, but without PTH in the subsequent 42 hours; and (3) Continuous exposure to PTH (Ctu), the cells were cultured with PTH during the first 6 hours and the subsequent 42 hours.
RESULTSThe bone-forming activities of ROB were increased in Itm and inhibited in Ctu. The IGF-I mRNA content in Itm cells was elevated only during the first 6 hours and that in Ctu cells was elevated at any time during an incubation cycle. The free IGF-I concentration in the medium of Itm cells was generally higher and that of the Ctu cells was generally lower compared with those of the Ctr cells. The IGF-I antibody significantly reduced the alkaline phosphatase activity within the cells of Ctr and Itm.
CONCLUSIONSPTH rapidly and constantly stimulates the IGF-I gene transcription of osteoblast. There was an obvious discrepancy between the IGF-I mRNA content within the osteoblast and the free IGF-I level around the osteoblast in either mode of PTH action. The IGF-I might be important for osteoblast-osteoblast communication and bone-forming activity, not only in intermittent PTH administration, but also in the physiological functioning of osteoblasts.

OBJECTIVETo study the relationship between polymorphism of inducible Nitric Oxide Synthase (iNOS) gene and the susceptibility of intestinal type stomach cancer and stomach cardia cancer in Chinese people.
METHODSA community-based case-control study was designed. Ninety-three intestinal type of stomach cancer and 50 stomach cardia cancer patients with endoscopy and pathology diagnosis were identified as cases. Two hundred and forty-six controls served as controls.
RESULTSC-->T polymorphism was found in exon 16 of iNOS gene, which changed the coding amino acid from serine to leucine, and formed a recognition site identified by Tsp 509 I restriction enzyme (we called it C-->T polymorphism). The T allele gene frequency in the control group was 13.21%. No statistically significant difference was found between C-->T polymorphism alone and the increased susceptibility to intestinal stomach cancer or stomach cardia cancer. A significant type 2 multiplicative interaction was found in increasing both the risk of intestinal stomach cancer and stomach cardia cancer when both C-->T polymorphism and tobacco smoking exposure existed. An additive interaction model, which showed statistically significant difference, was found to increase only the risk of stomach cardia cancer when CagA antibody shared negative but C-->T polymorphism occurred.
CONCLUSIONC-->T polymorphism of iNOS gene was considered as one of the possible susceptible genes, which specifically increased the risk of tobacco-related but CagA negative types of intestinal stomach cancer and stomach cardia cancer.
