Chinese Journal of New Drugs and Clinical Remedies 2001;20(3):182-184
AIM: To compare the therapeutic effects and adverse reactions of nicardipine and labetalol injection in treating acute and severe hypertensions. METHODS: Sixty-seven patients in nicardipine group (M 46, F 21; age 52 a± s 11 a) were given nicardipine 2 mg in 0.9 % sodium chloride or 5 % glucose injection 10 mL within 2 min iv, first, and then given 30 mg nicardipine in 0.9 % sodium chlocide or 5 % glucose injection 250 mL by continual intravenous infusion for 6 h. Sixty-one patients in labetalol group (M 41, F 20; age 53 a±9 a) received 50 mg labetalol in 5 % glucose injection 20 mL by intravenous once. The treatment could be repeated every 15 min, in case it was less effective, but the total dose should be no more than 200 mg. RESULTS: The treatment for the nicardipine group and the labetalol group, reached the marked effect within 5 min. The total marked effective rate was all 100 % (P>0.05). Severe adverse reactions occured in the two patients (one occured significantly lowering of blood pressure, and the other aggravated asthma) in the labetalol group. CONCLUSION: Intravenous nicardipine and labetalol are fast and smooth in reducing the blood pressure of the patients with acute and severe hypertension, but the safety of nicardipine is superior to that of labetalol

OBJECTIVETo evaluate the effect of different subgingival root exposure methods, namely, crown lengthening or forced eruption, and different ferrule lengths on fracture resistance of a residual root restored with a carbon fiber post-and-core system.
METHODSFifty-six extracted endodontically-treated mandibular first premolars were sectioned 1.0 mm coronal to the buccal cementoenamel junction. All the models were divided randomly into seven groups that each consist of eight roots. Group A was given non-ferrule as control. Simulated crown lengthening was performed for the dentin ferrule design in the cervical tooth structure for Groups B, C, and D with a ferrule length of 1.0, 2.0, and 3.0 mm, respectively. Simulated forced eruption was performed with a ferrule length of 1.0, 2.0, and 3.0 mm in the cervical tooth structure for Groups E, F, and G, respectively. After restoration with prefabricated carbon fiber post-and-core system, each specimen was embedded in a self-cured acrylic resin block from 2.0 mm apical to the margins of a cast Ni-Cr alloy crown, then loaded at 150 degrees from the long axis in a universal testing machine at a crosshead speed of 1.0 mm min(-1) until fracture. Data of failure loads and fracture mode were recorded and analyzed.
RESULTSMean failure loads for Groups A to G were (1.13 +/- 0.15), (1.27 +/- 0.18), (1.02 +/- 0.11), (1.05 +/- 0.12), (1.63 +/- 0.14), (1.92 +/- 0.19), and (1.93 +/- 0.15) kN, respectively. The effects of root exposure method and ferrule design differed significantly, and two factors exhibited significant interaction (F=33.396, P<0.0001). When the ferrule lengths were the same, fracture loads in the simulated forced eruption groups were significantly higher than those of the simulated crown lengthening groups (P<0.001). No statistical differences in fracture mode were observed among all groups (P=1.00).
CONCLUSIONMore than 1.0 mm ferrule placement on the apical crown margin by using forced eruption significantly increases fracture resistance.

3.Research progression of ?-SYN in Cancer
Journal of International Oncology 2006;0(11):-
?-Synuclein (?-SYN ) .previously identified as a breast cancer specific gene, has a wildly tumor expression profile mainly in advanced stage. As a special chaperone,?- SYN stimulates the proliferation and metastasis of tumor cells through interacting with estrogen receptor and (or) BubR1. Meanwhile, it is also detectable in the serum or urine from tumor patients, which indicates that?- SYN could be potential as a tumor marker for diagnosis and prognosis.

Purpose To measure the nuclear morphological parameters of breast cancer to study the relationship between nuclear mor-phological parameters and ER, PR, HER-2 expression, and clinicopathologic features of breast carcinoma. Methods 388 cases of breast cancer specimens were collected and molecular classification was made according to ER, PR and HER-2 expression. the nucleus parameters were measured by image analysis software after HE staining. The difference among groups was statistically analysed, and follow-up was done by phone or by hospitalization. Results Among the 4 groups of breast cancer case, the differences of circle diame-ter, area and perimeter edges of the nucleus were statistically significant (P<0.05). Nuclear morphometric quantitation between ER+/PR+ patients and ER-/PR- patients was statistically significantly differentice (P<0.05). The majority of patients with ER-/PR- were histological gradeⅢand poor survival rate (P<0.05). The disease-free survival in Luminal A type was higher than that of Basal-like type (P<0.05), and its overall survival was higher than HER-2 over-expression (P<0. 05) and Basal-like type (P<0.05) . Conclusion The nucleus morphological quantitation in breast cancer is of significant difference, which has certain reference value in its molecular typing. The result of ER, PR and HER-2 expression, combined with nuclear morphology measurement, are meaningful to the treatment and assessment of prognosis.

Objective By exploring the state of residents' living condition, it is helpful to promote the living condition of residents and improve the quality of medical services. Methods A qualitative re-search was conducted on 13 residents in 4 hospitals in Beijing by depth interview during April to May 2016, and the data were collected and analyzed by using Colaizzi seven step method. Results In terms of work, the residents had specific work, and the interpersonal relationship was more harmonious. In learning, residents were able to take the initiative to learn, and hoped to get more help in scientific research. In life, residents faced multiple pressures from the economy and the family. In the subjective cognition, the cogni-tion of resident was rational and objective. Conclusion The residents' work shows a heavy workload, and while working the residents need to take the study and the life pressure into account. And the residents can rationally recognize their role. To improve the living status of the resident physician, we need to integrate multiple forces, to promote the integration of live doctors into the hospital culture, and enhance their sense of existence. We also need to improve the construction of the system and improve the protection of live training physicians to enhance their sense of security. Most important of all, the whole society should pay more attention to the living condition of the residents and enhance their sense of access.
