ObjectiveTo discuss the feasibility and effect of clinical application of the single-bag and double-chamber anus tube.MethodsPatients who needed retention enema and non-retention enema(80 cases) were divided into 2 groups with 40 cases in each group.The test group was given enema by single-bag and double-chamber anus tube.The control group was given enema by traditional rubber anus tube.The reaction and clinical effect were compared between the two groups.ResultsIn the test group,pain and malaise lessened,intestinal cleaning was good,enema liquid reservation prolonged,the satisfaction degree of patients improved,compared with that of the control group (P<0.01).ConclusionsClinical application of self-made single-bag and double-chamber anus tube can give lesser pain and better effect of patients,and it improved satisfaction degree of patients and efficiency of nursing work greatly.

Objective To seek the best method for security precaution of elderly inpatients.Methods Elderly patients(296 cases) from January to August in 2006 and elderly patients(336 cases) from January to August in 2007 were divided into the control group and the improved group.The improved group received selective safety precaution measures after assessment of crisis degree by nurse security scale.The control group was given routine security nursing measures.The hospitalization time and incidence of unsafe events were compared in the two groups. Results The two groups were different in the following aspects:hospitalization time, incidence of unsafe events,satisfaction degree of family members,shift time of nurses,satisfaction degree of nurses. Conclusions To supply selective security nursing for elderly patients after assessment of crisis degree by nurse security scale at the admission day could decrease the incidence of un-safe events and hospitalization time.At the same time it shortened the shift time and increased shift efficien-cy to realize the win-win relations between nurses and patients.

The international Non-governmental Organizations ( NGOs) have been playing an important role in the field of global health, which also represents a channel for countries' international experience. This research fo-cuses on the role of NGOs in global health, their governance tools, global health program management experience, and current status of development for Chinese NGOs. In light of international experiences, we suggest the Chinese government to support a few top NGOs to engage intensely in global health, build management and cooperation mechanism with NGO which will be considered as important complemertary role. The Chinese government shonld implement “major support and comprehensive improvement” strategy.

Objective To discuss the application effect of new physical therapy technique in the rehabilitation of patients with hand injury afte operation. Methods Patients with hand injury after operation (150 cases) were divided into the observation group (87 cases) and the control group (63 cases) randomly. The control group received routine treatment and nursing. The observation group was given irradiation by He-Ne laser therapeutic instrument, vinegar therapy and static electromagnetic field therapy. The rehabilitative effect after operation was compared between the two groups. Results The time for disappearance of pain and swelling in the obsevation group was shorter than that of the control group (P<0.05). Conclusions Application of new physical therapy technique in patients with hand injury afte operation could shorten time of rehabilitation and improve rehabilitative quality.

ObjectiveTo assess the microscopic features of alopecia areata(AA) by using in vivo confocal laser scanning microscopy(CLSM).MethodsBetween January 2010 and May 2011,26 male and 20 female patients diagnosed with AA were enrolled in this study.AA lesions and perilesional normal skin were examined by means of in vivo CLSM.Tissue specimens were obtained from the lesions and perilesional normal skin of 10 out of the 46 patients and subjected to routine histopathologic examination.ResultsThe number of hair follicles per unit area(cm2) was decreased in lesions of progressive AA and resting AA compared with normal perilesional skin(134.856 ± 18.301 and 147.159 ± 17.536 vs.301.613 ± 35.317,both P ＜ 0.05).Although the quantity of hair follicles increased in lesions of recovery AA((227.778 ± 16.861 )/cm2),but was still less than that in the normal perilesional skin (P ＜ 0.05).There was a lack of hair shaft in follicles,as well as an inflammatory infiltration in hair follicles,around hair follicles and capillaries in superficial dermis in lesions of progressive AA.The inflammatory infiltration was attenuated in lesions of resting AA.In lesions of recovery AA,the infiltration was further attenuated with an apparent growth of lanugos and terminal hairs.ConclusionsAs far as AA lesions are concerned,CLSM images are consistent with histopathological findings.CLSM may serve as a promising tool for monitoring efficacy and predicting prognosis based on hair growth cycle,hair follicle number,and inflammatory infiltration degree.

Objective To evaluate the changes in the expression of cytochrome cholesterol side chain cleavage enzyme (P450scc) in the brain of morphine-dependent rats. Methods Twenty-four male SD rats aged 4-8 months weighing 180-200 g were randomly divided into 3 groups (n = 8 each): group Ⅰ normal saline (group NS), group Ⅱ morphine dependence (group MD) and group Ⅲ morphine withdrawal (group MW). In group MD and MW, the rats were given intraperitoneally increasing doses of morphine starting from 5 mg/kg to 10, 15, 20, 30, 40 and 50 mg/kg twice a day for 7 days. In group NS, the rats were given equal volume of normal saline instead of morphine. The rats were decapitated 1 h after last injection in group NS and MD. In group MW, naloxone 2 mg/kg was given 1 h after last injection, and then the animals were decapitated 30 min after withdrawal symptoms were observed. The brains were immediately removed and the frontal cortex, hippocampus, striatum and thalamus were separated. The expression of P450see was determined by Western blot. Results The expression of P450scc in the frontal cortex, hippocampus and striatum was significantly decreased in group MD and MW compared with group NS (P<0.05). Conclusion The down-regulation of P450scc expression might be involved in the development of morphine dependence, but it is not involved in the morphine withdrawal.

Objective　To study the effects of transforming growth factor-β1 (TGF-β1) and transforming growth factor-α (TGF-α) on the growth and invasive potentials in human bladder tumor cells.　Methods　The effects of TGF-β1 and TGF-α on the growth of EJ cell line and the effects on MMPs and TIMP-2 were studied by means of MTT,Western Blot and RT-PCR methods.　Results　(1)TGF-β1 and TGF-α tended to inhibit the growth of EJ cells but statistically nonsigficant.(2)Higher levles of MMP-9 mRNA but lower levels of MMP-2,TIMP-2,MT1-MMP mRNA were found in EJ cells following the treatment with TGF-β1.The same was true for the expression of MMP-2,TIMP-2 mRNA in TGF-α groups.However,MMP-9 mRNA was not found in both TGF-α groups and the control groups. (3)TGF-β1 (0.1,1.0 ng/ml) enhanced MMP-2 protein but not the TIMP-2 protein,while TGF-β1 (5.0,10.0 ng/ml)decreased TIMP-2 protein but not on MMP-2.In TGF-α groups,when the concentration was 1.0,5.0,10.0ng/ml,TIMP-2 protein expression was decreased but MMP-2 did not.When the concentration reached 100.0 ng/ml,it increased MMP-2 protein level,not the TIMP-2 protein.　Conclusions　TGF-β1 and TGFα do not inhibit the proliferation of EJ cells whereas the enhanced-invasiveness and metastasis may be associated with regulating the expression of MMPs and TIMP-2.

Objective: To compare the pharmacokinetic c haracteristics of amphoterici n B liposomes injection (LAmB) with market amphotericin B injection (MAmB) in ra bbits by intravenous administration. Methods: LAmB and MAmB wer e intravenously ad ministrated to rabbits at a single dosage of 1 mg*kg －1. The AmB concent rations i n plasma samples were determined by HPLC, and the pharmacokinetic parameters wer e calculated by means of 3P97, and ANOVA were done by means of the Excel softwar e. Results: The concentration- time data of LAmB and MAmB after intravenous administration were best fitted acc ording to three compartment-model with a weight of 1/C and 1 respectively . After a singl e intravenous administra tion, C max　of LAmB and MAmB were 8.4±2.1 and 2.4±0.6 mg*L －1, AUC were 22.5±6.8 and 9.0±1.9 mg*h*L －1, CL were 0.050±0 .024 and 0.114 ±0.022 L*h －1, V c were 0.13±0.04 and 0.46±0.18 L , respectively. Comparing with MAmB, all rabbits showed high plasma levels, large area under the curve values and low cl earance, small apparent volume of distribution of LAmB. Conclusion: There were several striking differences between the pharmacokinetics properties of LAmB and MAmB in jection in rabbits. All changes of the pharmacokinetics properties will be advan tageous to reduce toxicity and improve therapeutic effect.
