Objective We discussed the influence of diary therapy for out-of-hospital rehabilitation of schizophrenia patients with first hospitalization. Methods Ninety schizophrenia patients with first hospitaliza-tion and who were during rehabilitation period were randomized into the intervention group and the control group with 45 cases in each group.The two groups both received systemic antipsychotics medication.The control group adopted general health education while the intervention group got diary therapy based upon general health education.The treatment effect was evaluated by medical and nursing staff with abundant experience using the self-medication compliance questionnaire,the brief psychiatric rating scale(BPRS)and social disability screening schedule(SDSS)at the first day,6th month and first year after intervention. Results The total score of BPRS,SDSS,medication compliance and relapse rate in the intervention group was statistically better than those of the control group. Conclusions Diary therapy could facilitate the recovery of racial function,improve the medica-tion compliance,reduce the relapse rate and increase life quality for schizophrenia patients.

BACKGROUND:Some studies have showed that the accuracy and surgery outcome of the percutaneous pedicle screw implantation was superior to open surgery, but the relationship between the angle of pedicle screws and screw stability is stil unclear in previous studies. OBJECTIVE:To investigate the effect of different angles of implanted screws on the stability of pedicle screw. METHODS:A total of 30 vertebral specimens of adult pigs were selected and screws were implanted respectively according to different coronal and sagittal angles. The maximum pul-out strength of screws from each specimen was tested by machine. Load-displacement curves were drew and statistical y analyzed. RESULTS AND CONCLUSION:The maximum pul-out strength and maximum energy of screw with 10° and 15° coronal and sagittal angles implantation were significantly better than those of 0° angle group (P<0.05). When the stress exceeded the maximum pul-out strength, the pul-out strength of screw decreased gradual y. The curves in coronal and sagittal 10° and 15° angle groups was similar, and the slope was better than 0° angle group (P<0.05). These results confirm that the angle of the implanted screw provides effective assistance to the stability of percutaneous pedicle screw. After the looseness of the screws, the pul out strength shows a steady downward trend.

Objective To study the expression of high mobility group box 1 (HMGB1),matrix metalloproteinase-9(MMP-9) and vascular endothelial growth factor-C (VEGF-C)gene in papillary thyroid carcinoma (PTC) and their significance.Methods Expression of HMGB1,MMP-9,VEGF-C proteins and HMGB1 mRNA was detected by technology of immunohistochemistry(SP) and in situ hybridization in 58 cases of PTC tissues,20 cases of thyroid adenoma tissues,25 cases of nodular goiter tissues and 10 cases of normal thyroid tissues.Results Expression of HMGB1,MMP-9,VEGF-C proteins and HMGB1 mRNA in PTC tissues was much higher than that in the 3 non-cancerous tissues (P ＜ 0.05).The positive expression rate of HMGB1,MMP-9 proteins and HMGB1 mRNA was closely associated with the thyroid carcinoma size and lymph node metastasis (P ＜0.05).There was also closely association between the positive expression rate of VEGF-C protein and lymph node metastasis(P ＜ 0.05).The positive expression rate of HMGB1,MMP-9,VEGF-C proteins and HMGB1 mRNA had no association with patients' sex or age(P ＞ 0.05).The expression of HMGB1,MMP-9 and VEGF-C proteins had positive correlation with each other(P ＜ 0.05).The expression of HMGB1 protein and HMGB1 mRNA was also positively correlated with each other(P ＜0.05).Conclusion Expression of HMGB1,MMP-9,VEGFC proteins and HMGB1 mRNA in PTC is correlated with the progress,invasion,metastasis of PTC,by detecting them may help to predict the clinical progress and prognosis.

Objective To explore ear reconstruction using autologous rib cartilage ear framework by multi-layer spliced sculpture in microtia patients.Methods From Feb 2010 to May 2011,29 microtia patients were subjected to ear reconstruction using autologous rib cartilage ear framwork by four-layer spliced sculpture.Results In one operation 29 patients achieved 2 cm transverse height of reconstructed ears which were basically coincidence with the normal side.Patents and their families were all satisfied with the results.Follow-up of 3-12 months showed that only 1 case reconstructed-ear height was significantly lower transverse process.Owing to sleeping position,the patient did not protect the reconstructed ear,leading to frequent reconstructed-ear pressure.Conclusions The method of multi-layer spliced sculpture autologous rib cartilage ear reconstruction has good clinical effect.It can make reconstructed ear reach nomal transverse height and avoid the third rib cartilage transplant operation to continue increasing the transvers height.

BACKGROUND: Expectant treatment for intertrochanteric fractures in elderly patients with osteoporosis and other chronic diseases can easily lead to complications of lying in bed.OBJECTIVE: To evaluate the results of percutaneous compression plating system (PCCP) for intertrochanteric fractures in elderly patients. METHODS: Thirty-two cases of elderly intertrochanteric fractures treated with PCCP admitted from June 2007 to June 2009 and 40 cases of elderly intertrochanteric fractures treated with dynamic hip screw system (DHS) were reviewed. The operative bleeding, operative time and curative effect were compared.RESULTS AND CONCLUSION: The operative bleeding and operative time in the patients receiving PCCP were significantly lower than those in the patients receiving DHS. There was not statistical significance between the curative effects about the two methods. PCCP applied in elderly patients with intertrochanteric fracture can get satisfactory effects, and the system is operated simply with minimally invasive surgery, which is beneficial to reduce surgical complications.

Aim To investigate the effects of all-trans retinoic acid and benazepril on the expression of ?-smooth muscle actin in rats with glomerulosclerosis.Methods 80 Wistar male Rats were randomly assigned into the following groups: control group,model group,ATRA treatment group and benazepril treatment group,20 rats in each group.GS rats were uninephrectomized and injected with adriamycin(5mg?kg-1) after one week through the tail vein.All rats were sacrificed at the 12th week,GS was evaluated by glomerulosclerosis index(GSI) system.The expression of ?-SMA was assessed by reverse transcription-polymerase chain reaction(RT-PCR) and immunohistochemistry.Results Comparing with control group,the expression of ?-SMA mRNA and protein were decreased significantly in ATRA treatment group and benazepril treatment group(P0.05).Conclusions The postponed effects of ATRA and benazepril on GS were evident and equivalent.

ObjectiveTo explore the effect of estrogen on osteoblast apoptosis induced by serum hungry in vitro.MethodsOsteoblasts of second or third generation from newly born SD rats calvaria were divided randomly into the control group, serum hungry group and serum hungry with estrogen group. Cells of each group were incubated for 24 h, 48 h, 72 h, 5 d, 7 d and 14 d, then labeled using TUNEL staining and examined for morphological characteristics of apoptotic cell under light microscopy after incubated for 72 h. The rates of apoptotic cells of each group were examined with flow cytometry.ResultsThe cells of the control group showed normal appears, the serum hungry group had many cells with purple and blue particles in nuclei, but serum hungry with estrogen group had less such cells. The rate of apoptotic cell significantly increased in serum hungry group and decreased in serum hungry with estrogen group compared with the control group examined with flow cytometry (P<0.05).ConclusionEstrogen can repress osteoblasts apoptosis of rats induced by serum hungry.

Objective To investigate the current prevailing status of endemic fluorosis in the Yellow River basin of Shandong Province and to provide the scientific evidence for making strategies in prevention and control.Methods Nine counties were chosen to carry out the epidemiological investigation.The content of fluoride in drinking water was determined by F-ion selective electrode and dental fluorosis of children aged 8～12 years old was diagnosed by Deans method.Results Water fluoride content was determined in 1761 fluorosis villages,among which 606 villages had water fluoride content≤1.00 mg/L,accounting for 34.41%(606/1761);1155 villages had water fluoride content＞1.00 mg/L,which accounted for 65.59%(1155/1761).The highest water fluoride content was 11.33 mg/L.Water fluoride content of 618 water-improving and defluoridation projects had been determined,among which 449 projects had water fluoride content≤1.00 mg/L and accounted for 72.65%(449/618),169 projects had water fluoride content＞1.00 mg/L and accounted for 27.35%(169/618),the highest water fluoride content was 5.85 mg/L.The total rate of dental fluorosis of children aged 8～12 years old was 45.03%(25 579/56 804) and the index of dental fluorosis was 0.80. Conclusions In the Yellow River basin in Shandong Province,up to 50.00%in the villages the water fluoride content exceeds the county standard(≤1.00 mg/L).The prevalence of endemic fluorosis in the basin hasn't been effectively controlled.So the counterrneasures for endemic fluorosis should be carried out as soon as possible.
