This paper analyzed existing problems,corresponding solutions and research directions of the effectiveness evaluation indexes of coro-nary heart disease health education and proposed that China should build a standard,reasonable and perfect effectiveness evaluation index system of coronary heart disease health education which combines short-term and long-term evaluation indexes and some relevant standard scales, with the purpose of en-hancing the working efficiency of educators and promoting scientization,standardization and normalization of effectiveness evaluation of health education.

AIM: To explore the relationship between methylation status of promoter region 5′CpG island and the biological phenotype in human colorectal cancer RKO cell lines. METHODS: RKO cells were treated with selective DNA methyltransferase (DNMTs) inhibitor, 5-Aza-2′-deoxycytidine (5-Aza-CdR), for 72 h. Methylation-specific PCR (MSP), T-A clone and DNA sequence analysis were used to detect 5′CpG island methylation status of p16/CDKN2 tumor suppresor gene. Cell growth, cell cycle arrest and apoptosis were analyzed by MTT, flow cytometry (FCM), fluorescent dye staining and transmission electron microscope. RESULTS: DNMTs inhibitor (5-Aza-CdR) effectively reversed the hypermethylation status of 5′CpG island. The effects of 5-Aza-CdR on cell growth inhibition (P

Objective To know the situation of teaching and teacher preparation for nursing under-graduates, and then reference to reasonable clinical teaching mode. Methods Investigated clinical pre-ceptors from 30 hospitals by serf-designed questionnair to know their basic situation, and then investigated nursing undergruaduates who had enter school in 2004 to know their evaluation about their preceptors in the aspect of basic quality. Results In professional tides, most of the teachers are nurse-in-charge, and have been working over 10 years, but qualification certificates levels were low and 50% of them teaching. Experience was short and not qualified to the popurse of bachelors degree, nurse-in-charge and more than five years nursing experience. The ratio in thesis writing, teaching training and awards are rather low. There were teaching assessment from students, mainly in teaching and research initiative.

BACKGROUND: Peritonitis is the common detective complications at the end-stage of renal failure patients during continuous ambulatory peritoneal dialysis (CAPD) treatment, which easily repeatedly occurred if not handled properly. Although the plumbing designs of peritoneal dialysis have done a lot of effort and improved in recent years, it still hard to avoid. OBJECTIVE: To explore the relative factors and treatments of infectious peritonitis complicated with CAPD. METHODS: Totally 115 cases received CAPD were selected, including 55 males and 60 females, aged (56.2?.7) years. 68 cases of which were suffered infectious peritonitis, aged (58.5?.3) years. All received a (30.3?.5)-month CAPD treatment. The relative factors such as the nutrition situation, whether complicated with diabetes mellitus or not, culture background, domestic environment, whether operating by special person and so on were investigated, and the relationship between those factors and infectious peritonitis were analyzed. The pathogen method was used to check pathogenic bacteria, and those patients were treated with irrigation of abdominal cavity and antibiotics in two ways, that is, systemic and intra-abdominalcavity. Hemodialysis instead of CAPD was used in those infectious peritonitis patients.RESULTS AND CONCLUSION: Those patients with good nutrition situation, higher culture background, better domestic environment, and operating by special person had low chances to infect peritonitis. And those patients with diabetes mellitus had high chances to infect peritonitis. Treatments of abdominal cavity and anti-infection in two ways-systemic and intra-abdominal cavities were effective to those infectious peritonitis patients. Gram-positive bacteria were the most common pathogen, which were susceptive to vancomycin and cefazolin. If the pathogen was gram-negative bacteria, etimicin sulfate, amikacin, and imipenem cilastatin could be selected. Infectious peritonitis complicated with CAPD affected by many factors. CAPD patients should be provided better nutrition and domestic situation. Also patients should operate in aseptic ways. Doctors should choose proper patients who can operate CAPD right.

A 28-year-old male patient presented with a 4-year history of a solitary brown mass, and a 1-year history of multiple small papules on the left chest. Skin examination showed a quasi-round brown firm mass measuring about 1.2 cm × 1.1 cm × 1.0 cm in size on the left chest, and several brown papules with diameters ranging from 3 to 5 mm on the right side of the mass; no enlarged lymph nodes were detected in the left axilla on palpation. The mass and papules were completely resected, and histopathological examination showed clustered nevus cells in the superficial dermis of the mass and small papules, and the diagnosis of intradermal nevus was considered. There was a desmoplastic nodule in the mass, nevus cells were scattered among the fibers in the nodule, and giant nevus cells were also observed; the nevus cells in the nodule were relatively larger, epithelioid or spindle-shaped with round or spindle-shaped nuclei, obvious nucleoli, and rare mitotic figures. Immunohistochemical study showed that the nevus cells in both the intradermal nevus and proliferative nodule were positive for S100; the nevus cells in the superficial dermis of the intradermal nevus were positive for Melan-A and HMB45, while the nevus cells in the proliferative nodule were negative for Melan-A and HMB45; both the intradermal nevus and proliferative nodule tissues showed a Ki-67 index of 1%, positive staining for CD34, but negative staining for P16 and P63. Finally, the patient was diagnosed with intradermal nevus associated with desmoplastic nodule.

To observe the germistatic and germicidal effects of origanum volatile oil (OVI) on the dysentery bacteria, the abdominal cavity of mice was infected with Shigella sonne (Sh. sonnei) and Shigella flexneri (Sh. flexneri) F2a. After OVI was given to the mice via gastric lavage, the effects of OVI on the infected mice were observed. The minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) for dysentery bacteria were determined in vitro. The results showed that origanum volatile oil showed obvious protective effect on mice infected with Sh. sonnei and Sh. flexneri F2a and it had germistatic and germicidal effects on dysentry bacteria. We are led to conclude that origanum volatile oil is an effective medicine against the infection of dysentery bacteria.

Objective To investigate the effects of compound radix angelicae sinensis injection on oocyte and segmentation sphere injured by subacute exposure to diesel exhaust particles (DEP) in female mice. Methods Two hundred and ten 21-day-old ICR female mice were randomly divided into 5 groups: the control group (group A), DEP group (group B), DEP+low-dose group (group C),DEP±middle-dose group (group D) and DEP+high-dose group (group E). There were 42 mice in each group. The mice were inoculated with 30 μ1 DEP suspension at 12.0 μg/μl (group B-E) or the same volume of vehicle (PBS, group A) on pharynx posterior wall by sample pipettor beginning at day 21 and repeated every 3 days for 4 times. The mice were sacrificed three days after the last exposure.Compound radix angelicae sinensis injection containing 75 (group C), 150 (group D) and 300 (group E)grams of crude drug, respectively, which was intraperitoneally administered for each mouse daily from the day of the first DEP inoculation till the day before sacrifice, consecutively for 12 days. The general conditions were observed, and the body weight and ovary/body weight ratio were tested. Superoxide dismutase (SOD) activity, malondialdehyde (MDA) and reduced glutathione (GSH) contents in ovarian tissues were assayed. Rates of survival, germinal vesicle breakdown, extrusion of the first polar body and in-vitro fertilization, and quantity of mitochondrial DNA for oocytes were investigated.Ultrastructural changes of oocytes were observed. Results ( 1 ) No significant difference of the body weight was found among all the groups (P＞0. 05). The ovary weight, ovary/body weight ratio, ovary SOD and GSH content were significantly decreased in groups B [( 1.5 ± 0. 6) mg, ( 7.2 ± 2. 5) × 10-5 ,(192. 10±23.67) nU/mg prot and (262.40 ± 31.60) nmol/mg prot], and C [( 1.7 ± 0. 2) mg,(8.9±0.6)× 10-5, (198.92±24.27) nU/mg prot and (271.66±14.58) nmol/mg prot] and D [(2. 1±0. 2) mg, (9. 8±1. 1)×10-5, (214. 37±27. 19) nU/mg prot and (285. 93±9. 55) nmol/mg prot] as comparing to groupA [(3. 3±1. 5) mg, (15.4±7.3)×10-5, (292. 30 ± 40. 03) nU/mg prot and (367.98±24.59) nmol/mg prot (P＜ 0. 05 or P＜0.01); and significantly increased in group E [(3. 7±1.1) mg, (18. 7±5. 4)× 10-5, (279. 10±12. 63) nU/mg prot ]and (353. 59±10. 61) nmol/mg prot]comparing to group B (P＜0. 01). MDA content was signi-ficantly increased for groups B, C and D [(3. 88±0.35) nmol/mg prot, (3. 62 ± 0. 19) nmol/mg prot and (2. 63 ± 0. 34) nmol/mg prot] comparing to group A [(2. 18±0. 44) nmol/mg prot](P＜0. 05 or ＜0. 01, respectively); and significantly decreased for group D and E (2. 35±0. 37 nmol/mg prot) comparing to group B (P＜0. 01). (2) In all observed time points, oocyte survival rate in group B and C, extrusion rate of the first polar body and in-vitro fertilization rate in group B, C and D were significantly lower than in group A (P ＜ 0. 05 or ＜0. 01), and all those in group E were significantly higher than in group B (P＜0. 05). Rates of germinal vesicle breakdown were 100% in all five groups. (3) Logarithmic values of mitochondrial DNA copy numbers in group C, D and E were significantly lower than in group A; whereas significantly higher in group C and D than in group B (P＜0.01). (4) Normal appearance for oocytes in group A was seen. In groups B and C, a number of cytoplasmic organelles were dramatically degenerated in part of the oocytes and some necrotic oocytes were seen. Large body of mitochondria in the oocytes swelled and vacuolized in group D, while such changes dincished to a lesser extent and scope in group E. Conclusions Compound radix angelicae sinensis injection exerts a favorable curative and protective effect on oocyte and segmentation sphere injured by subacute DEP exposure in female mice.
