Objective To observe the effect of rational-emotive therapy(RET)on rehabilitation of patients with depression after stroke.Methods 62 hemiplegic patients with depression after stroke were randomly divided into the RET group and control group with 31 cases in each group.All patients were evaluated with Hamilton Rating Scale for Depresstion(HAMD)and Barthel Index(BI)before and after treatment.Results After treatment,the scores of HAMD and BI of the patients in the RET group was superior to those in the control group(P<0.01).Conclusion The rational-emotive therapy is effective to improve not only depressive symptoms but also the quality of living.

Objective To study the relationship between mutation of rpsL drug-resistant gene in L-forms of Mycobacterium tuberculosis and drug-resistance to streptomycin in pneumoconiosis patients.Methods A total of 52 clinical isolated strains of Mycobacterium tuberculosis L-forms were collected from 97 pneumoconiosis patients.The mutation of rpsL gene was detected by PCR-SSCP,and the drug-resistance to streptomycin was performed by routine antimicrobial susceptibility test(AST).Results The results of drug susceptibility test showed that 26 in the 52 clinical isolated strains were drug-resistant to streptomycin.The streptomycin-resistant rate was 50.00%(26/52).The gene mutation rate of rpsL detected by PCR-SSCP was 40.38%(21/52).The coincidence rate of two experimental results was 80.77%(21/26).Conclusion High detectable rate of streptomycin-resistant strains in Mycobacterium tuberculosis L-forms was found by PCR-SSCP.The application of PCR-SSCP may possess important value for guiding clinical medication of pneumoconiosis patients complicated with tuberculosis among coal workers

OBJECTIVEThis work lays the foundation for establishing a digital model database with normal occlusion. A digital dental cast is acquired through grating projection, and model features are measured through reverse engineering.

METHODSThe grating projection system controlled by a computer was projected onto the surface of a normal dental model. Three-dimensional contour data were obtained through multi-angle shooting. A three-dimensional model was constructed, and the model features were analyzed by using reverse engineering. The digital model was compared with the plaster model to determine the accuracy of the measurement system.

RESULTSThe structure of three-dimensional reconstruction model was clear. The digital models of two measurements exhibited no significant difference (P > 0.05). When digital and plaster models were measured, we found that the crown length and arch width were not statistically different (P > 0.05), whereas the difference between the crown width and arch length was statistically significant (P < 0.05).

CONCLUSIONThe reconstruction of a digital model by using the grating projection technique and reverse engineering can be used for dental model measurement in clinic al and scientific research and can provide a scientific method for establishing a digital model database with normal occlusion.

Objective To investigate the regulative effect of the extract of Radix Ranunculi Ternati,Radix Sophorae Flavescenti,Prunella vulgaris L.and Stellera chamaejasme L.on cellular immunity induced by multiple drugs resistant bacillus tuberculosis(MDR-TB) from pneumoconiosis patients complicated with tuberculosis in rats.Methods MDR-TB model in rats was induced by MDR-TB.Normal control group were feed by standard feed,model group were irrigated by normal saline,and the other groups were respectively feed by the extract of Chinese herbal medicines.The content of IFN-γ,IL-4,IL-10 and IL-12 were examined by ELISA.RT-PCR was used to detect the mRNA levels of them.Results The content of IFN-γof the four extracts of Chinese herbal medicines were (2.01 ±0.73 ),( 1.92±0.56),( 1.98 ±0.67 ) and (1.94±0.59) pg/ml,IL-4 were (6.01±1.46),(6.12±1.35),(6.47±1.46) and (6.15±1.44) pg/ml,IL-10 were (12.09±3.07),( 12.45±4.01 ),( 12.13±3.43) and (12.54±3.78) pg/ml,IL-12 were (2.99±0.89),(2.75±0.84),(3.02±0.86) and (2.89±0.75) pg/ml.Compared to the model group,they resulted in significant in serum IFN-γ,IL-12,IL-4 and IL-10 (P＜0.05 or P＜0.01 ),the mRNA levels of them were significantly (P＜0.05 or P＜0.01 ).Conclusion The four extracts of Chinese herbal medicines can enhance the cellar immunological function in rats from up-regulation of the level of genetic transcription,accordingly provide the theory base of healing of pneumoconiosis patients complicated with tuberculosis with them.

Objective To study the effectiveness and safety of combined laparoscopy and gonadotropin-releasing hormone agonist (GnRH-a) in the treatment of endometriosis (EM).Methods From January to December 2010,198 patients with EM undergoing treatment in Department of Obstetrics and Gynecology,Beijing Anzhen Hospital were randomly divided into three groups,which include 52 cases treated by only laparoscopy in laparoscopy group; 76 cases treated by laparoscopy combined with domestic Leuprolide acetate with dose of 3.75 mg every 28 days in Leuprolide acetate group; 70 cases treated by laparoscopy combined with imported Goserelin acetate with dose of 3.6 mg every 28 days in Goserelin acetate group.The efficacy,pregnancy rate and adverse reactions were compared among the three groups.Results Thirteen cases lost following up,including 3 cases in laparoscopy group,6 cases in Leuprolide acetate group and 4 cases in Goserelin acetate group.(1) Effective rates:effective rates were 47 ％ (23/49)in laparoscopy group,77％ (54/70)in Leuprolide acetate group and 74％ (49/66)in Goserelin acetate group.Compared with laparoscopy group,the effective rate of Leuprolide acetate group and Goserelin acetate group was significantly elevated (P ＜ 0.05).There was no statistically significant difference between Leuprolide acetate group and Goserelin acetate group (P ＞ 0.05).(2) Recurrence rate:recurrence rate were 33％ (16/49) in laparoscopy group,13％ (9/70)in Leuprolide acetate group and 12％ (8/66)in Goserelin acetate group.Compared with laparoscopy group,the recurrence rate of Leuprolide acetate group and Goserelin acetate group was significantly declined (P ＜ 0.05).There was no statistically significant difference between Leuprolide acetate group and Goserelin acetate group (P ＞ 0.05).(3) Pregnancy rate:the number of patients require fertility were 28 cases in laparoscopy group,39 cases in Leuprolide acetate group and 35 cases in Goserelin acetate group.After 2 years follow up,pregnancy rate of 62％ (24/39) in Leuprolide acetate group and 60％ (21/35)in Goserelin acetate group were high than 39％ (11/28)in laparoscopy group significantly,which did not reached significant difference (P ＞ 0.05).(4) Adverse drug reaction:rates of a adverse reactions were 21％ (15/70) in Leuprolide acetate group and 20％ (13/66) in Goserelin acetate group,including irregular vaginal bleeding associated with low estrogen level.There was no significant difference in adverse reactions (P ＞ 0.05).Conclusions Compared with laparoscopy alone,laparoscopy combined with GnRH-a is more effective in treatment of,which exhibit lower recurrence rate,higher pregnancy rate and fewer adverse reactions.Domestic Leuprolide acetate have similar safety and efficacy compared with imported GnRH-a.

Objective The aim of this article is to discuss the relation between serum uric acid and prehypertension, and to evaluate the influence of age, obesity, fasting plasma glucose (FPG) and lipids in Chinese adults. Methods All the 14 451 non-hypertensive samples were analyzed for blood pressure, body mass index (BMI), FPG, lipids and serum uric acid. Results The serum uric acid levels were stratified by quintiles, after adjustment for relevant factors, OR values of prehypertcnsion increased with the elevated uric acid levels. Serum uric acid level was 200-380 μmol/L, it had a linear relationship with the risk of prehypertension, 200 μmol/L as a turning point for this linear relationship, FPG could affect their correlation (P ＜ 0.0001 ). Conclusions Serum uric acid was associated with prehypertension, independent of metabolic risk factors. The associations were not significant in old individuals. FPG may modify the associations.

The interactions between genetic variations and dietary factors in type 2 diabetes mellitus have attracted some attention. Several studies revealed that dietary carbohydrate quality and quantity and increased dietary fat intake might interact with genetic variations of type 2 diabetes mellitus and increase risk of this disease. Genome-wide association studies suggest that genetic variance may modulate the association between dietary pattern and type 2 diabetes mellitus.
