Objective To explore the impact of social support and perceived stigma on depression for people living with HIV/AIDS. Methods A total of 114 patients recruited into our study. Date were collected by Self-rating Depression Scale (SDS), Social Supporting Rating Scale (SRSS) and Berger HIV Stigma Scale (BHSS) for patients. Analysis of Moment Structures (AMOS) version 7.0 software was used to conduct the path analysis. Results The total score of patients′depression, SRSS and BHSS were (52.22± 10.28), (29.09±5.98), (109.02±14.59) points, and there was correlation between the three (r=0.425-0.676, P<0.05). Social support revealed direct effects on depression and affected depression indirectly via BHSS.The paths′ total coefficients was-0.47. BHSS as intermediary variable between social support and depression, the paths′ total coefficients was 0.64. Conclusions The level of depression, SRSS and BHSS were not fine for HIV/AIDS. Depression are directly affected by SRSS and BHSS, BHSS has a greater moderating effect on these relationships. Interventions developed on the basis of influencing factors of depression should be applied to improve patients′depression status.

The subject of clinical medicine contains abundant humanism educational material.When students start the clinic learning and contact with the patients for the first time,clinical teacher should endeavor to cultivate medical students' humanistic spirit in clinical practice.The paper discussed how to merge humanistic spirit into medical clinic teaching by illustrating the gynecology and obstetrics teaching.

Objective: To evaluate the application of two-dimension and color Doppler ultrasound in diagnosis and differential diagnosis of fascial space infection in maxillofacial region. Methods: Retrospective analysis was conducted on 87 cases of maxillofacial space infections, among which there were 6 suspected cases of accompanying tumor.Results: In the 87 cases, 53 had abscess formation, confirmed by operative drainage or puncture biopsy. The pathological studies revealed 2 cases of Non-Hodgkin's lymphoma, and 1 case of branchial cleft cyst accompanied with infection. The 3 cases showed characteristic appearance in ultrasonic imaging. The space infection presented stronger echogenicity than that in tumors. In this study, 95% (83/87) cases showed grey or medium echogenic dots, while 4.5% (4/87) cases did not show obvious echogenic dots due to a large amount of abscess, and 2 cases of tumors, however, did not show any echogenic dots. In addition, 87% (76/87) cases had few blood flow in the lesion areas, and 22% (2/87) cases had much blood flow in the lesion areas. All cases showed that the lesion areas and the blood flow reduced obviously with enhanced echo following anti-inflammatory treatment except 2 cases accompanied with tumor without obvious changes in lesion areas and blood flow.Conclusion: The ultrasonic diagnosis with two dimension and color Doppler ultrasound has high accuracy in diagnosis of maxillofacial space infection, with accordance rate up to 96.6%, much higer than CT/MRI. It is suggested that the two dimension and color Doppler ultrasound can be used as a prior choice of diagnosis.

Objective To investigate the experience and needs of caregivers of patients with hematopoietic stem cell transplantion (HSCT) , in order to provide the basis for targeted intervention. Methods Using qualitative phenomenological research methods, semi- structured interviews of 10 caregivers of HSCT patients were conducted, then the data were summarized and analyzed. Results Four themes were extracted: heavy caregiving burden, adaptation to the caregiving role, professional support needs, humanistic care needs. Conclusions The medical staff should strengthen the health education on HSCT caregivers to improve their ability and their own health concerns, alleviate their psychological pressure, and mobilize social forces to reduce the burden of care.

Objective To explore the effects of parent-adolescent conflict and cohesion on relational aggression among junior students.Methods Parent-adolescent Conflict Questionnaires,Parent-adolescent Cohesion Questionnaires,and the Relational Aggression Questionnaires were used in investigating 392 junior students.Results The level of relational aggression of junior students was low (22.52±5.15).There was no differences between relational aggression of male students (22.93± 5.43) and female students (22.00± 4.73) (P＞ 0.05),and of grade 1 students(22.72±5.14)and grade 2 students(22.64±5.67),grade 3 students(21.93±4.22) (P＞0.05).The students' relational aggression showed a significantly positive correlation with frequency and intensity of parent-adolescent conflict(r=0.269,r=0.307,r=0.268,r=0.271,P＜0.01),and negative correlation with father-adolescent cohesion(r=-0.171,P＜0.01).Parent-adolescent cohesion was negative predictor of relational aggression(β=-0.123,P＜0.05),and the intensity of parent-adolescent conflict was positive predictor(β=0.301,P＜0.01).Conclusion Parent-adolescent conflict and cohesion have significant effect on relational aggression among junior students.

Objective Monitoring the thyroid hormone levels in patients before and after renal transplantation to realize the relationship between thyroid hormones and renal function.Methods Fifty-seven patients were subdivided into stabled graft function group (50 cases) and delayed graft function (DGF) group (7 cases).Thirty healthy men served as control group.Serum triiodothyronine (T3),thyroxine (T4),thyroid-stimulating hormone (TSH) and serum creatinine (Scr) were determined respectably before transplantation and on different days after transplantation.Correlations between thyroid hormones and Scr at 10th day after transplantation were analyzed.Results Serum T3 and T4 levels before transplantation in the two groups were significantly lower than those in the control group (P＜0.01).These four parameters levels had no significant difference between stabled graft function group and DGF group (P＞0.05).In stabled graft function group:T3 level was decreased obviously by 30％ in the 1st day after transplantation,which was higher than the others,elevated at the 1st week post-transplantation,reached the normal range.at the 2nd week post-operation,and higher than pre-transplantation (P ＜ 0.01) at 3rd week; T4 revealed a decrease trend after transplantation and was elevated at 10th day post-transplantation,returned to the pre-transplantation level at 3rd week; TSH had slight decrease after operation,and had no significant difference among every period in comparing with pre-transplantation; Scr revealed a decrease trend continuously and returned to the normal level at the 7th day post-transplantation.In DGF group,Hormones levels were obviously decreased as compared with stabled graft function group; T3 reached the normal range at the 3rd week post-transplantation,whereas T4 returned to pre-transplantation levels at the 30th day; TSH had a significant decrease at the 5th day,and began to increase at the 10th day post-operation; Scr retuned to the normal range at the 30th day post-operation.The correlation coefficients between Scr and T3,T4 were 0.546 and 0.423 respectively.Conclusion There is a significant correlation between thyroid hormones and renal function (T3,T4).Monitoring the thyroid hormones,specially T3,can diagnose renal function change.

BACKGROUND:Studies have shown that the number of osteoblasts is often decreased after osteoporosis, and osteoblast replacement therapy becomes a new target for the treatment of osteoporosis. OBJECTIVE:To observe the osteogenic differentiation of human bone marrow mesenchymal stem cels cultured in dexamethasone, vitamin C and beta-glycerophosphate. METHODS:Mesenchymal stem cels were isolated and purified from adult bone marrow using human lymphocyte separation medium. The expression of cel surface markers was detected by flow cytometry. Cel ultrastructure was observed by transmission electron microscope. Then, the bone marrow mesenchymal stem cels were cultured in osteogenic induction medium containing dexamethasone, vitamin C andβ-glycerophosphate, and RT-PCR was used to detect the bone morphogenetic protein-2 mRNA expression after osteogenic induction. RESULTS AND CONCLUSION:A large number of adherent cels were visible as fibrous growth at 2 weeks after culture and strongly expressed CD44, CD29, but did not express CD34, CD45. These cels could be induced to differentiate into osteoblasts, and express bone morphogenetic protein-2 mRNA. Alizarin red staining and alkaline phosphatase staining were positive for the cels. These findings suggest that human bone marrow mesenchymal stem cels cultured in dexamethasone, vitamin C and beta-glycerophosphate can differentiate into osteoblasts, and has a potential for the treatment of osteoporosis.

Objective To observe the effect of peroxisome proliferators activated receptor gamma(PPAR-?)on phenotypic transforming of vascular smooth muscle cells(VSMC)in hypertension.Methods Spontaneous hypertension rats(SHR)and WKY rats both aged 4 months were included.SHR rats as well as WKY rats were divided to be fed with normal chow,and chow added with rosiglitazone(10 mg?kg-1?d-1)for 16 weeks.VSMC were isolated from SHR rats and WKY rats and cultured by patch-attaching method,then respectively divided into 3 groups after treated with genetic recombination technology:normal VSMC,PPAR? overexpressed VSMC and PPAR? silenced VSMC.Expressions of OPN and ?-SMA,which respectively represent the undifferentiated and differentiated VSMC,were detected by Western blotting.Cell proliferation was determined by detecting DNA synthesis and cell counting.The changes of arteries were evaluated pathologically.Results Rosiglitazone decreased blood pressure and ameliorated vascular remodeling of aorta in SHR rats.Aorta of SHR showed an upregulation of OPN and downregulation of ?-SMA,which could be inhibited by rosiglitazone.VSMC from SHR rats showed an upregulation of OPN and downregulation of ?-SMA,and increased cell proliferation.These changes were all inhibited by rosiglitazone.In the cells that overexpressed PPAR?,the cell proliferation rate was lower,and the expressions of OPN and ?-SMA were depressed,compared with the corresponding control cells.Conclusion PPAR-? could inhibit the phenotypic transforming of VSMC,and this might be responsible for the amelioration of vascular remodeling in hypertension.
