By analyzing the scope and demands of mental health service in general hospitals, the authors point out that at present domestic general hospitals are confronted with such problems as insufficiency of resources for mental health service, low recognition rate of dysphrenia, and lack of systematic consultations and liaison in psychiatric work. Then they put forward a number of measures for improving mental health service in general hospitals: ①establishing a department of psychiatry in each general hospital; ②widely conducting consultations so as to maintain a strong liaisom in psychiatric work; ③genuinely achieving the transformation of the medical mode; ④strengthening education in psychological medicine and the spread of popular science so as to broaden the channel and coverage of mental health service and meet the needs of reform and development of the health cause in the contemporary era.

With the development of surgical techniques in dental implantation, traditional teaching methods can not keep pace with the developing teaching situations.To resolve this problem,the live television technique has been applied in the teaching of dental implant surgery.The practice of live television technique not only stimulates students' learning interests,but also turns the passive education model into an interactive model with better teaching results.

BACKGROUND:With the development of genetic engineering and tumor molecular biology, gene therapy has acted as a new treatment mode for tumors. OBJECTIVE:To investigate the impact of gene silencing ABCE1 on growth, proliferation and migration of human cervical cancer cel s XB1702. METHODS:siRNA sequences of ABCE1 were designed and synthesized to transfect XB1702 cel s using LipofectamineTM 2000. Cel s transfected with NC siRNA carrier served as controls, and untransfected cel s acted as blank group. After RNA interference, the expression of ABCE1 mRNA and protein was detected by western blod assay;cel cycle was detected using flow cytometry;cel counting kit-8 test, scratch healing assay and cel invasion assay were used to evaluate the effects of ABCE1 silence gene on XB1702 cel proliferation, migration and invasion ability. RESULTS AND CONCLUSION:ABCE1 mRNA and protein expression in the experimental group was significantly lower than that in the control group and blank group (P<0.05). Growth rate in the experimental group was significantly slowed, cel s were arrested in G 0/G 1 phase, and the number of S-phase cel s was reduced. Compared with the control group and blank group, XB1702 cel proliferation was inhibited significantly in the experimental group, and cel migration and invasion was significantly decreased (P<0.05). These results showed that specific interference with gene expression of ABCE1 can inhibit the migration of human cervical cancer cel s XB1702, and restrain tumor cel proliferation;therefore, the siRNA sequence of ABCE1 may be an effective target for treatment of cervical cancer.

BACKGROUND:Peptide hydrogel has good plasticity, and it can fil the injured site very wel; therefore, to use this material as a scaffold is a feasible exploration in bone and cartilage tissue engineering. OBJECTIVE:To test the effect of bone marrow mesenchymal stem cels combined with injectable peptide hydrogel and chondrogenic factors for repair of articular cartilage defects in rabbits. METHODS:Bone marrow mesenchymal stem cels from rabbits were isolated and cultured. A ful-thickness bone-cartilage defect model, 5 mm in diameter and 3 mm in depth, was made on the left knee joint of rabbits, and the right knee joint of rabbits with no treatment was used as control after modeling. There were three experimental groups: self-assembling peptide hydrogel group, peptide hydrogel+chondrogenic factors group, and peptide hydrogel+chondrogenic factors+bone marrow mesenchymal stem cels group. Transforming growth factor β1, dexamethasone and insulin-like growth factor 1 were mixed as chondrogenic factors and added into self-assembling peptide hydrogel or bone marrow mesenchymal stem cels. Twelve weeks after treatment, animals were sacrificed for gross and histological observation, X-ray radiography, and histological evaluation using immunohistochemistry method. RESULTS AND CONCLUSION:At 12 weeks after treatment, the self-assembling peptide hydrogel group showed excelent results in the cartilage repair, and better achievements in safranin-O staining, colagen II immunostaining, and histological scores than the other groups (P < 0.05); the peptide hydrogel+chondrogenic factors group had better repair effects similar to the self-assembling peptide hydrogel group, but the expression of proteoglycans was higher than that in the control group (P < 0.01); there were poorer repair effects and more osteophytes in the peptide hydrogel+chondrogenic factors+bone marrow mesenchymal stem cels group than the the peptide hydrogel+ chondrogenic factors group. Experimental findings indicate that the self-assembling peptide hydrogel can repair cartilage defectsin situ and improve cartilage repair, which is expected to improve current repairing effects on cartilage defects.

OBJECTIVETo observe the clinical efficacy on fibromyalgia syndrome treated with acupuncture at the acupoints selected from the affected meridians based on the location differentiation and the heavy moxibustion at painful points by the randomized controlled trial with medication.

METHODSThirty-two patients of fibromyalgia were randomized into an acupuncture-moxihustion group and a medication group, 16 cases in each one. In the acupuncture-moxibustion group, acupuncture at the acupoints selected from the affected meridians based on the location differentiation and the heavy moxibustion at painful points were applied, once every two days, three times a week, for 4 weeks totally. In the medication group, tramadol sustained release tablets and amitriptyline were prescribed for oral administration, once a day, for 4 weeks. The follow-up visit was conducted for 4 weeks in the two groups. Before and after treatment and in follow-up visit, the revised version of the fibromyalgia impact questionnaire (FIQR) and visual analogue scale (VAS) were adopted for assessment and comparison of the efficacy between the two groups.

RESULTSAfter treatment and in follow-up visit, FIQR score and VAS score were improved apparently as compared with those before treatment in the two groups (all P<0. 05). At the end of treatment, the differences were not significant statistically between the two groups (all P>0. 05). But the differences were significant in follow-up visit (all P<0. 05). The scores in the acupuncture-moxibustion group were improved persistently, but those in the medication group were rebound.

CONCLUSIONThe acupuncture at the acupoints selected from the affected meridians based on the location differentiation and the heavy moxibustion at painful points are safe and effective in the treatment of fibromyalgia syndrome and present the better persistent effect as compared with the combined medication of tramadol sustained release tablets and amitriptyline.

Objective:To investigate influences of bicortical anchora ge on the values of natural frequency of dental implants. Methods: Using the commercial code of SolidWorks, 3-D models of a screw-shaped dental i mplant and a mandibular bone segment were generated. After the 3-D implant-bon e complex was meshed by ABAQUS software, effects of bicortical anchorage on the buccolingual and axial first-order natural frequencies of the implant were comp uted. Results:Bicortical anchorage increased the buccolingual na tural frequencies and the axial natural frequencies of the implants by a maximu m of 13.77% and 107.40% respectively. The apical anchorage depth in the cortical bone had an insignificant effect on further increase of implant stability. Conclusion:Bicortical anchorage can increase the stability of dental implants, especially in the axial direction.
