Objective To explore the most convenient and valid tool for screening mental disorders among servicemen. Methods Soldiers and officers stationed at Guilin were enrolled for the study. They were first examined with the Symptom Check-list 90 (SCL-90), Cornell Medicine Index (M-R)[CMI(M-R)], University Student Personality Inventory (UPI) and WHO neurosis screening schedule respectively. Then they were subjected clinical interview and examination individually, and clinical diagnosis of mental disorder was made according to CCMD-3 standard. The validity of each questionnaire was evaluated by using Criterion-related Validity. Results The sensitivity of WHO neurosis screening schedule was found to be 100%, and the specificity was 92.1%. SCL-90 and CMI (M-R) yielded similar results, their sensitivity was found to be 46.9% and 43.4%, and the specificity to be 86.1% and 78.9%, respectively. The sensitivity of UPI was found to be 83.1% and the specificity 46.1%. Conclusion The WHO neurosis screening schedule is the best in both sensitivity and specificity of validity, but its practice is time-consuming and laborious, which limits its application. SCL-90 and CMI (M-R) are imperfect in sensitivity of validity, and they cannot screen out the mental disorder in more than a half of the subjects. In a group test, they can hardly serve as a screening tool. UPI can screen out most of the mental disorder, and its sensitivity of validity reaches 83.1%. Additionally, the UPI questionnaire contains fake-test items, which could retest those who were missed due to untruly or not conscientiously answer the questionnaires. An acceptable way to obtain a true screening test is to give the individuals a propaganda of mental health and explain the questionnaires for 30 minutes before the test, which helps the examinee to understand the procedure and accept the questionnaires, so that the results of the test could be more reliable. In conclusion, UPI is a valuable screening tool to be recommended.

· AlM: To study the effect of bone mesenchymal stem cells ( BMSCs ) and chondroitinaseABC ( ChABC ) on photoreceptor apoptosis in the retina of sodium iodate-induced rats.
·METHODS:Forty Sprague Dawley rats ( SD rats) were intraperitoneally injected with NalO3 (30g/L, 100mg/kg) to establish the retinal degeneration models ( postnatal 28d).These rats were devided into 4 groups.Group A was not injected, group B was injected with BMSCs, group C was injected with BMSCs and ChABC, and group D was injected with phosphate buffer saline ( PBS).After 28d, subretinal injection were applied. Hematoxyln - eosinstaining ( HE ) , tunel and immunohistochemistry were performed at 21d after subretinal injection.
· RESULTS: Photoreceptor number and photoreceptor apoptosis rate of B and C groups were more than those of A and D groups, and there was significant difference statistically ( P <0.05 ) . Photoreceptor number and photoreceptor apoptosis rate of group B were compared with those of group C, and there was no statistical significance between B and C groups ( P>0.05 ) .Glial fibrillary acidic protein ( GFAP) was expressed by BMSCs after intraocular injection.
· CONCLUSlON: BMSCs and ChABC injected into subretinal space may alleviate photoreceptor apoptosis so as to protect retinal photoreceptor cells in degenerated rats.

Objective To investigate the effects of Puerarin on glucose and lipid metabolism and gastric motility in early period type 2 diabetic (T2DM) rats.Methods Rat model of T2DM was established by high fat-sugar diet fed and low-dose streptozotocin-treated. SD rats were divided randomly into normal control group (NC), normal+Puerarin group (NP), diabetes control group (DC) and diabetes+Puerarin group (DP). NP and DP rats were given Puerarin 400 mg/(kg?d) once per day for 5 weeks, NC and DC rats were given PBS. Half time of gastric emptying and emptying rate were evaluated by SPECT. The serum level of FBG, GSP, FFA, TC, TG and INS were measured by kit.Results Compared with NC group, DC rats had higher FBG, FFA, TC, GSP, TG and emptying rate, but INS and half time of gastric emptying decreased significantly (P<0.05,P<0.01). Compared with DC group, TG, GSP, FFA and emptying rate of DP rats were reduced (P<0.05), but had more half time of gastric emptying (P<0.05). The results of multivariate stepwise regression analysis showed that FBG related to half time of gastric emptying.Conclusion Type 2 diabetic rats have faster gastric motility, higher blood glucose and lipid. Puerarin might improve the disorders of GSP, TG, FFA and gastric emptying in diabetic rats.

To observe BAG-1, EGFR, and PARP-1 expressions in invasive breast cancer and its correlation with clini-cal pathological indicators, as well as to evaluate their clinical significance. Methods:The BAG-l, EGFR, and PARP-1 expressions in a tissue microarray of invasive breast cancer and peritumoral tissues were detected through immunohistochemical staining. The clinical and pathological significance of BAG-1, EGFR, and PARP-1 were evaluated. Results:The BAG-1, EGFR, and PARP-1 expression lev-els are higher in invasive breast cancer tissues than in peritumoral tissues (P<0.05). BAG-1 expression in invasive cancer tissues is not related to age, tumor site, lymph node metastases, and clinical TNM staging of patients, but is related to size, grade, ER, PR, and HER-2 expressions and molecular subtype (P<0.05). EGFR expression is related to size, clinical TNM staging, and molecular subtype (P<0.05). PARP-1 expression is related to grade, lymph node metastases, ER, and molecular subtype (P<0.05). BAG-1 expression is not significantly correlated with EGFR and PARP-1 in all cases, but BAG-1 and PARP-1 expressions are positively correlated in tri-ple-negative breast cancer tissues (P<0.05). Results of the univariate analysis revealed that the BAG-1 and PARP-1 expressions and the molecular subtypes are associated with the prognoses of breast cancer patients. Multivariate analysis revealed that BAG-1 and PARP-1 expressions are factors that are independent of the prognosis. Conclusion: BAG-1, EGFR, and PARP-1 overexpressions in human breast tissues suggest that BAG-1, EGFR, and PARP-1 are related to breast cancer development. BAG-1, EGFR, and PARP-1 are poten-tial biomarkers of breast cancer diagnosis and prognosis.

The 1.23 kb DNA fragment encoding the early protein EP0 of pseudorabies virus (PRV) Ea strain was amplified by PCR technique and cloned into pBluescriptII sk+.Three sequencing plasmids containing the partial fragment of the EP0 gene were constructed and the sequences were obtained by Sanger's sequencing technique. Compared with PRV InFh strain, there were multipile site-mutations and a deleted-mutation in the EP0 gene of PRV strain Ea,and the diversity of amino acid residues also existed.Then, the EP0 gene was inserted into an expression vector, pET-28a, fused into the downstream of the 6ΧHis-Tag in frame, to yield the expression plasmid pETEP0. After induction by IPTG, a high expression of fusion protein was obtained, SDS-PAGE analysis and Western blotting showed that the fusion protein was 62kD and the protein was specific to antisera against PRV Ea strain. This indicated that the EP0 gene be expressed in BL21(DE3) and the expression products have immuno-genicity.
