objective: To evaluate the effects of the pendulum appliance on arch length, arch width, overbite and overjet. Methods: Pendulum appliances were applied for distalization of maxillary molars in 37 patients whith class Ⅱ malocclusion and 1-Ⅱ degree crowded dentition in upper dental arch. Pretreatment and posttreatment model analysis was conducted. Results: 37 patients treated for 18.2?4.5 weeks with pendulum appliance were accomplished . The increase of arch arc length between the maxillary first molars was (17.36?4.38) mm, the decrease of anterior arch width (-3.04?1.59) mm, and the decrease of posterior arch width (-1.29?2.01) mm . Differences between the pretreatment and posttreatment were significant, including arch arc length between the maxillary first molars ( P

Objective:To evaluate effects of traction arch combined with protraction on dental and skeletal changes in patients with Angel Ⅲ malocclusion in mixed dentition.Methods:Seventeen patients with Angle Ⅲ malocclusion were selected and treated with traction arch combined with protraction. Cephalometric radiographs were taken 6 months before the initiation of treatment, at the initiation of treatment and 6 months after treatment.Cephalometric analysis was used to examine the dental and skeletal changes.Results:Significant changes of maxillary anterior displacement and mandibular downward and backward rotation were observed in the seventeen patients:SNA increased 2.6?,A point moved forward 3.1 mm. The overjet correction of anterior teeth was 5.2 mm, 63% of the overjet correction was due to skeletal changes and 37% due to dental changes. Conclusion:Traction arch combined with protraction is a simple and effective apparatus in the treatment of Angle Ⅲ malocclusion.

Objective To detect the change of the plasma hydrogen sulfide in patients with chronic heart failure (CHF) and explore its clinical significance.Methods A total of 118 patients with CHF was enrolled in this study.According to the NYHA standard,they were classified into grade Ⅱ (34 cases),grade Ⅲ (54 cases),grade Ⅳ (30 cases).The patients were divided into normal treatment group and sodium nitroprusside treatment group with 59 cases each.Another 30 healthy person were selected as control group.The plasma hydrogen sulfide level was detected by spectrophotometer.Results The plasma hydrogen sulfide level in CHF patients and healthy person was (32.45 ± 3.86),(54.26 ± 5.63) μ mol/L,and there was significant difference (P ＜ 0.05).The plasma hydrogen sulfide level in CHF patients of grade Ⅱ,Ⅲ,Ⅳwas (43.26 ±4.73),(31.87 ±4.12),(23.66 ±3.54) μmol/L,and there was significant difference (P＜0.05).The plasma hydrogen sulfide level before treatment in normal treatment group and sodium nitroprusside treatment group was(31.66 ± 3.75),(33.04 ± 4.02) μ mol/L,and there was no significant difference between two groups (P ＞ 0.05).The plasma hydrogen sulfide level after treatment in normal treatment group and sodium nitroprusside treatment group was (36.83 ± 4.32),(44.54 ± 4.68) μ tmol/L,and there was significant difference (P ＜0.05).The plasma hydrogen sulfide level after treatment in two groups was increased compared with that before treatment,and there was significant difference (P ＜ 0.05).The total effective rate in normal treatment group and sodium nitroprusside treatment group was 42.4％ (25/59) and 67.8％(40/59),and there was significant difference between two groups (P ＜ 0.05).Conclusions The abnormal plasma hydrogen sulfide level may be involved in the occurrence and development process of CHF,which could be used as a factor to monitor the disease.The upregulation of plasma hydrogen sulfide level can significantly improve the prognosis of CHF patients.

The herpes simplex virus type 1 (HSV-1) infected-cell protein 27 (ICP27) is an essential,highly conserved protein involved in various steps of HSV-1 gene regulation as well as in the shut-off of host gene expression during infection.It functions primarily at the post-transcriptional level in inhibiting precursor mRNA splicing and in promoting nuclear export of viral transcripts.Recently,many novel functions performed by the HSV-1 ICP27 protein were shown,including leptomycin B resistance,inhibition of the type I interferon signaling,regulation of the viral mRNA translation and determining the composition of HSV-1 virions.

Even in secular societies, a small portion of patients find their spirituality to help cope with illness. But for the majority of patients, psychosocial and spiritual needs are neither addressed nor even considered a relevant factor by health care professionals. To measure such specific needs, the Spiritual Needs Questionnaire (SpNQ) was developed. The aim of this study was to validate the Chinese version of the SpNQ (SpNQ-Ch) and thus to measure psychosocial and spiritual needs of Chinese patients.

Objective To observe the effect of Wenxiao Decoction in treating the patients with carotid atherosclerostic (CAS) plaque and assess the safety. Methods Sixty patients with CAS plaque were randomly allocated to treatment group (33 cases) and control group (27 cases). The control group was given routine therapy, and the treatment group was given Wenxiao Decoction additionally. And they were further divided into half-year treatment group and half-year control group, 1-year treatment group and 1-year control group. Carotid artery color Doppler ultrasound and hepatorenal function were examined before and after treatment. Results Compared with the control groups after therapy, the average numbers of plaques, maximal plaque thickness, Crouse plaque integral were decreased both in 1-year and half-year treatment groups (P<0.05, P<0.01). The plaque stability of 1-year treatment group was better than that of half-year treatment group. The average numbers of plaques, plaques size and Crouse plaque integral increased in control groups after routine therapy (P<0.05, P<0.01). Bilateral common carotid artery diameter, intima-medial thickness (IMT) and hepatorenal function had no statistical difference between before and after treatment both in treatment and control groups (P>0.05). Conclusion Wenxiao Decoction is effective and safe in treatment of CAS plaque, and plaque stability is more obvious with the extension of treatment time.

Objective To analyze the impact factors for early renal damage in type 2 diabetic patients by the classification tree model.Methods A total of 601 patients with type 2 diabetes were enrolled.According to glomerular filtration rates and urine albumin quantification,the patients were divided into type 2 diabetes group (418 cases) and early diabetic renal damage group (183 cases).The clinical data of the patients were recorded to analyze the main influential factors for the microalbuminuria of type 2 diabetic patients using the Exhaustive CHAID classification tree algorithm.Results Six important explanatory variables were screened out by the classification tree model from the 34 candidate variables related to early renal damage,including fibrinogen,history of hypertension,retinopathy,Cys C levels,SBP and peripheral neuropathy.Elevated fibrinogen was the main factor.Conclusion The classification tree model can analyze the major influential factors of early renal damage in type 2 diabetic patients effectively,and it can help develop the prevention and treatment methods.
