Objective To explore the clinical effects of enema combined with massage therapy on jaundice in premature infants.Methods Seventy-five premature infants with jaundice were randomly divided into 3 groups,enema combined message therapy group(group A),abdominal massage therapy group(group B),and double-side phototherapy group(group C).All 3 groups were received the same formula fee-ding,intravenous nutrition and identical drug treatment.Group A was given enema with mixed kaiselu and normal saline together with 60 times clockwise abdominal massage once a day for 2 weeks.Group B only received abdominal massage twice per day for 2 weeks.Transcutaneous bilirubin(TB) indexes of all the premature infants in the 3 groups were detected and transformed into total TB concentrations every morning,through version of MINOLTA JM-102 transcutaneous bilirubin radiometer made in Japan.When TB index counted more than 196.58 ?mol/L,group A and B were given single-side phototherapy for 24 hours.Neither enema nor abdominal massage was given to group C,and double-side phototherapy was applied when TB indexes were above 196.58 ?mol/L.Daily TB indexes,duration of jaundice and phototherapy,time of meconium exhaustion,defecation times in each day,incidence of constipation and feeding intolerance were recorded.Results Duration of jaunhospitalized and phototherapy were significantly shortened in group A compared with those of the other groups.In 34 premature infants who were hospital for at least 2 weeks,TB indexes in group C were lower than those in group B on the 9th day.On the 12th day and the 14th day,TB indexes in group A and C were lower than those in group B(Pa

This study was aimed to establish determination method of content and related substances of piperaquine in A rtemisinin and Piperaquine Tablets, and to set the limit of related substance. HPLC was adopted on a SHISEIDO CAPCELL PAK C18 (4.6 mm í 250 mm, 5 μm) using an isocratic mobile phase consisted of acetonitrile: 0.1%trichloroaceticacid:triethylamine (18:82:0.2, V:V:V, pH 2.5) with a flow rate of 1.0 mL·min-1. The column tempera-ture was kept at 30oC and the detection wavelength was set at 216 and 237 nm, separately for the determination of related substance and content. The results showed that piperaquine and its related impurity can be separated effec-tively. The concentration-response relationship was linear over the range of 0.01-0.2 mg·mL-1 (R2=0.999 9). The av-erage recovery rate was 98.14% (RSD=0.77%, n=9). The minimum detection limit was 0.06 μg·mL-1. The solution was stable for 12 h. It was concluded that the method was specific, accurate, sensitive and suitable for the determi-nation of content and related substances of piperaquine in A rtemisinin and Piperaquine Tablets.

Objective To investigate the diagnostic significance of endoscopic findings in Henoch-Schonlein purpura(HSP),especially when abdominal pain preceded the cutaneous lesions.Methods The clinical data and gastroscopic findings in 37 cases of children with HSP were studied and analysed retrospectively in order to detect the pathological changes in the stomach and duodenum mucosa.The biopsy was taken in the pathological changeing place,and the relationship between clinical and endoscopic findings was analyzed.Results Detection rate of the pathological changes in the stomach and duodenum mucosa was 62.2%,31.3% of which experienced only cutaneous lesions,100% of which presented the acute abdominal pain.Three patients were not checked up the pathological changes.Of them,1 had arthritis,2 had Henoch-Schonlein nephritis.Characteristically endoscopic findings in the stomach and duodenum mucosa were found.The endoscopic findings included anabrosis,hyperemia,edema and hemorrhage.Conclusions Detection rate of the pathological changes in the stomach and duodenum mucosa is higher.Endoscopy is very helpful to the early diagnosis of HSP in children,especially abdominal pain presented firstly.

Objective To observe the effect of auricular point sticking on the sleep quality of patients undergone liver transplantation.Method The sleep quality was assessed by using sleep quality scale. The patients undergone liver transplantation were randomized into two groups, both receiving auricular point sticking, while the insomnia zone was selected in the observation group and non-insomnia zone was selected in the control group, 4 weeks as a treatment course.Result In 4 weeks after the transplantation, there were significant inter-group differences in comparing the scores of unfreshing sleep, difficulty falling asleep, nightmairs, medications, post-insomnia reactivity, and the total score of the self-rating scale of sleep (SRSS) (P＜0.05); in 2 months after the transplantation, there were significant differences in comparing the scores of sleep latency, sleep efficiency, sleep disturbance, sleep medications, daytime dysfunction, and the global score of Pittsburgh Sleep Quality Index (PSQI) between the two groups (P＜0.05), indicating that the sleep quality in the observation group was markedly improved. Three months after transplantation, there were no significant differences in comparing the sleep indexes between the two groups (P>0.05).Conclusion Auricular point sticking at the insomnia zone can markedly improve the short-term sleep disorder in patients after liver transplantation, and can reduce the dose of sleep medications.

To study the potential molecular mechanism of tumor angiogenesis in its microenvironment, we investigated the effects of HepG2 conditioned medium on the proliferation of vascular endothelial cell and vascular angiogenesis in our laboratory. Human umbilical vein endothelial EA. hy926 cells were co-cultured with HepG2 conditioned medium in vitro. The proliferation and the tubulogenesis of EA. hy926 cells were detected by teramethylazo salt azole (MTT) and tube formation assay, respectively. The results showed that the survival rate of the EA. hy926 cells was significantly increased under the co-culture condition. HepG2 conditioned medium also enhanced the angiogenesis ability of EA. hy926 cells. In addition, the expressions of intracellular VEGF and extracellular VEGFR (Flk-1) were regulated upward in a time-dependent manner. In conclusion, the proliferation of vascular endothelial cells and Vascula angiogenesis were improved under the condition of indirect co-culture.

Powder X-ray diffraction (PXRD) technology combined with cluster analysis method was used to classify 75 batches of crystalline ceftriaxone sodium into subtypes, the crystalline characteristics of each subtype were measured with scanning electron microscope (SEM). By comparing some parameters of these subtypes correlated to crystallization process of ceftriaxone sodium, such as salification rate, water content in different subtypes, as well as by studying different lattice stabilities, different compatibilities with rubber closures during accelerated stability tests, the key point to improve the quality of domestic ceftriaxone sodium was disclosed. The results of this paper indicated that the fine structure of the products could be controlled well by improving the salification and crystallization process. As a result, the subtype II of ceftriaxone sodium with high stability can be produced.

Objective To analyze rural doctors′ social mentality with the theory of relative deprivation.Methods 642 rural doctors from 225 villages of 1 5 counties in Shandong were selected for a questionnaire survey.The factor analysis method was used to reduce the scale dimension and simplify the scale.Analysis of rural doctors′vertical and horizontal relative deprivation was made based on different reference groups.Results Rural doctors tend to identify themselves with rural teachers and doctors in township hospitals,and 60.0% identify themselves as the low income group.39.9% of them found a higher income,while 33.5% of them found a higher social status.76.3% of them found their social contributions are higher.91.4% of them hold that villagers benefit from the new healthcare reform policies,while 65.9% of them hold themselves as benefiting from such policies.This indicates a low sense of achievement.Conclusions Compared with the reference groups,rural doctors feel an obvious sense of relative deprivation comparing both horizontally and vertically.They hold themselves as underpaid and have little sense of achievement for the policies.In this consideration,the government should increase subsidies to lift pay for rural doctors,and to identify their legitimacy,in order to stabilize these medical workers.

It was discovered in this experiment that 3 days after inoculation of the ascitic fluid from P_(388) leukemic mice, the positive percentages of AcP and ?-Gase of the lymphocytes within the TNC of the recipients were increased significantly, while the positive percentage of ANAE was decreased. All the positive percentages of the three enzymes of the thymocytes within the thymus were increased significantly, but no abnormal structural changes were seen in the thymus. No histological and cytochemical changes were found in the lymph nodes and the spleen. Nine days after inoculation, the leukemia cell infiltration, hemorrhage and cell degeneration occurred in all the thymus, lymph nodes and spleen of the mouse. The normal structures of the organs were destroyed. The positive percentages of the cytochemical reactions of the three enzymes in the lymphocytes were all increased significantly. At this stage, TNC was very difficult to be isolated from the thymus. The results indicate that thymus and TNC may have a close relationship with the development of this type of leukemia.
