The papers regarding moxibustion published in science citation index (SCI) journals for the recent 5 years were searched to explore the international tendency of moxibustion researches, which provided references for moxibustion to have a better internationalization. With methods of internet search and database search, a total of 116 papers regarding moxibustion were included. These papers were published in 40 kinds of journals, mostly in Britain and the United States. The journal with the highest impact factor was Stroke, which had 5729 points. The number and impact factor of these journals were inferior to those of acupuncture journal. Compared among these journals, the depth and width of moxibustion research were increasing year by year. The category of diseases related with moxibustion is mainly digestive system diseases, motor system diseases and urinary-genital system diseases. The type of papers was characterized with clinical observation and mechanism research. Researches related with moxibustion included moxibustion dose and safety. It was believed that the international recognition of moxibustion effectiveness, standardization of moxibustion manipulation, standardization research, etc. were needed to be solved in the further.

Objective:To evaluate the ability of calcium hydroxide removal using different irrigation methods and the effect on canal sealing.Methods:200 human single root canal premolar teeth were prepared.Divided the teeth randomly into 2 groups(each group 96 teeth,8 as control),one group filled with chemical calcium hydroxide and another filled with finished product calcium hydroxide.7 days after,divided each groups randomly into 6 subsets and remove the calcium hydroxide in the root canal(table1).Then each subset group choose 8 teeth randomly,observed by scanning electron microscope.Other specimens were obturated by lateral condensation of cold gutta-percha with a AH-Plus sealer,stained by Indian ink and then made into transparent teeth model.Results:At the same condition,there was no significant difference between group A and group B;the results of groups associated with ultrasonic were better than groups with injection syringe.The rinse solution EDTA was the best,distilled water was the worse.Dye penetration showed that the length of dye staining was no significant difference among all groups.Conclusion:Ultrasonic and sodium hypochlorite associate EDTA is the best method to remove the calcium hydroxide.But none of the methods and rinse solution used in this experiment can remove all of the calcium hydroxide.The calcium hydroxide remained influence on the root canal sealer is not predominance.

Objective To investigate the expression of estrogen receptor (ER), progesterone recptor (PR) and c-erbB-2 in breast cancer tissues and its relationship with prognostic factors. Methods The clinical data of 1 008 cases with breast cancer were retrospectively analysed. The relationship between the expression of ER, PR and c-erbB-2 in breast cancer tissues and the prognostic factors such as menopausal status, axillary lymph nodes metastasis and TNM stage was investigated. Results The mean presentation age of the 1 008 cases was (53.53?12.60) years. Invasive ductal cancer was the most common pathological type (80.5%). Postmenopausal ER-positive cases were significantly more than premenopausal ER-positive ones, and the clinical stage was lower (P

ObjectiveTo investigate sleep disorder of patients with depression and find out the regularity.Methods78 depression cases in the east-region of Shenyang were evaluated by Pittsburgh Sleep Quality Index (PSQI) questionnaire and mental health symptom checklist-90 (SCL-90). The results were contrasted with normal control group.Results63 depression cases (80%) had sleep disorder (PSQI scores≥8) and were significantly higher than normal control group. The PSQI evaluation showed that sleep quality, enter-sleep time, sleep efficiency, sleep disorder, hypnotige drugs, function of daytime and total scores of PSQI of the depression group were significantly higher than that of normal control group (P<0.05～0.01). The SCL-90 test showed that scores of somatic, obsessive, depressive, anxiety, phobia, paranoid and mental-illness, etc. and total quota of bad-sleep quality group were significantly higher than that of the fine-sleep quality group (P<0.05～0.01).ConclusionDepression patients have significantly descent in sleep quality, latter is often closely related to the mental psychotic expressiveness of somatic, obsession, depression, anxiety, phobia, etc.

Objective To evaluate the influence of different field-strength magnets(1.5 T and 3.0 T)on MRI artifacts caused by Ni-Cr alloy fixed prostheses.Methods The crown,bridge and upper denture fixed prostheses with different thickness were produced by Ni-Cr alloy as test samples,and were one by one put on the centre of water phantom for MR scanning with different field-strength magnets(1.5 T and 3.0 T).The artifact areas on these two field-strength magnets were measured and statistically compared.The plastic prostheses with the same shape and thickness as the test samples were served as controls.Results Ni-Cr alloy fixed prostheses could cause MRI artifacts,and the artifact areas increased with the mass of prostheses.However,no artifact area was found in controls.Compared with those on 1.5 T magnet,the MRI artifact areas significantly increased on 3.0 T magnet(P

Objective To explore the expression of tumor necrosis factor(TNF) ligand-related molecule-1A(TL1A) in mice with viral myocarditis(VM) and the role of astragaloside.Methods Fifty-five male Balb/c mice were randomly divided into 4 groups:control group,model group,low-dose intervention group and high-dose intervention group.Mice in model group,low-dose intervention group and high-dose intervention group were inoculated with 0.1 mL coxsackie B3 virus intraperitoneally.Then,mice in low-dose intervention group and high-dose intervention group were treated with 10 g?L-1 and 90 g?L-1 astragaloside solution,respectively.Mice in control group and model group were treated with 0.1 mL carboxymethycellulose solution.All mice were killed on the 15thday.Histological cross sections of heart were stained with hematoxylin-eosin and myocardial histopathologic scores were counted under optical microscope.The expressions of myocardial TL1A mRNA and protein were detected by reverse transcription polymerase chain reaction and immunohistochemistry.Results The mortality were 0,46.7%,40.0% and 13.3% in control group,model group,low-dose intervention group and high-dose intervention group,respectively.Compared with model group and low-dose intervention group,the mortality was significantly lower in high-dose intervention group(?2=9.46,8.95,Pa

Mitochondrial dysfunction has been implicated in the aetiology of sporadic Parkinson's disease but its role in the disease mechanism remains unclear.To investigate the effect of synuclein on mitochondrial dysfunction induced by rotenone.The human dopaminergic SH-SY5Y cells were used as a cell model.The cells over-expressed the wild-type ?-synuclein were treated with complex I inhibitor rotenone.The cell viability,complex I activity,Mitochondrial swelling and O2-content were tested at different time point-1w,2w,4w after rotenone treated.CCK-8 test results showed that the cell viability of overexpressed ?-synuclein(SH-SY5Y-Syn)was much lower than the control group(SH-SY5Y-Ctr).After administrating with rotenone about 1w or 2w the cell viability of SH-SY5Y-Syn became higher than that of SH-SY5Y-Ctr.On the 4th week the results were contrary to the first 2 weeks.Similar results were got when test the mitochondrial function.In the first 2 weeks after roteoone administrating,the mitochondrial function of SH-SY5Y-Syn was better than that of SH-SY5Y-Ctr.This suggest that the ?-synuclein could protect the mitochondrial against the injury induced by rotenone in the early stage-1w,2w,while this effect disappeared in the final stage-4w.

This study taking gestodene (GEST) as a model, investigated the factors affecting reservoir-type intravaginal ring (IVR)'s drug release. This paper reported a gestodene intravaginal ring of reservoir design, comprising a gestodene silicone elastomer core encased in a non-medicated silicone sheath, separately manufactured by reaction injection moulding at 80 degrees C and heating vulcanization at 130 degrees C is reported. The test investigated the factors affecting drug release through a single variable method, taking the drug release rates of 21 days as standards. When changing the thickness of the controlling sheath outside, the ratio of the first day of drug release and mean daily release (MDR), named the relatively burst effect, is closing to 1 with the thickness of controlling sheath increasing, while the 1.25 mm sheath corresponding to 1.04 controlled the burst release effectively; a positive correlation (r = 0.992 2) existed between the average drug release (Q/t) and drug loading (A) within a certain range. The C6-165 controlling sheath with high solubility of GEST is easier to achieve controlled release of the drug; GEST crystalline power is more effective to implement controlled release of drugs among difficent states of the drug. A 1/4 fractional segment core gives a relatively burst effect of 1.76, while the 1/1 and 1/2 are 1.93 and 1.87 separately, at the same drug loading, concluding that use of a fractional segment core would allow development of a suitable GEST reservoir IVR. In summary, GEST reservoir-type IVR could be adjusted by the thickness of controlling sheath, the loading of drug, the material properties of controlling sheath, the dispersion state of drug, the additive composition and structure of intravaginal ring, to control the drug release behavior and achieve the desired drug release rate.
