Objective To explore the psychological feelings of inpatients with AIDS, direct nurses to understand their psychological feelings in order to provide holistic nursing care. Methods Phenomenological method in qualitative research was adopted, 12 inpatients with AIDS were interviewed. Results The emo-tional feelings of inpatients with AIDS concerned mainly about: feeling shocked when they got to know they had affected with AIDS, wanting to commit suicide because of suffering, earnestly demanding for the com-panion of family members, the need for mental supports, planning to go on to work after feeling better be-cause of financial problems, worrying about children at home. Conclusions Nurses should estimate the changes in emotional reactions of inpatients with AIDS properly, understand their life conditions, and help them to promote their life quality by providing holistic nursing care.

Objective To compare the effects of Graves thyrotoxicosis patients treated by long-term use of anti-thyroid drug ( ATD) and without long-term use of ATD ,and to explore the application value and safety of ATD be-fore 131 I treatment.Methods 62 cases with Graves hyperthyroidism were divided into the two groups according to whether received the long-term ATD treatment.The curative effects,hormone level and safety were compared.Results The success rate of ATD group was 43.75%, the success rate of without ATD treatment group was 56.67%, the difference between the two groups had statistical significance (Ridit=15.152,P=0.000).The thyroid mass,FT3, FT4 ,TSH levels after treatment between two groups had no significant differences , but the difference of the highest iodine uptake rate in 24h had significant difference (t =6.954,P<0.05).The adverse reactions in ATD treated group and ATD untreated group were 7 cases(21.88%) and 3 cases(10.00%),there was statistically significant difference between the two groups(χ2 =4.563,P=0.032).Conclusion Long-term ATD therapy before 131I treatment can reduce the highest iodine uptake rate in 24h,reduce the clinical curative effect and increase adverse reaction rate .

Objective To observe the changes of circulating Tc 17 and Treg cells in the patients with colorectal adenoma(CRA)and the patients with colorectal cancer (CRC)and to investigate the correla-tions between them.Methods Peripheral bloods were collected from 63 patients (30 CRA and 33 CRC) and 20 healthy subjects .The proportions of circulating Tc 17 and Treg cells in peripheral blood mononuclear cells ( PBMCs) were detected by flow cytometry .The serum levels of IL-17A and IL-23 were measured by ELISA.Results Compared with healthy controls , the proportions of circulating Tc 17 and Treg cells as well as the serum levels of IL-17 A and IL-23 in CRA and CRC groups were significantly up-regulated ( P<0.05).The proportions of circulating Tc17 cells and the serum levels of IL-17A and IL-23 in CRC group were significantly higher than those in CRA group (P<0.05), but there was no significant difference in the expressions of Treg cells between the two groups .As the disease progressed , the proportions of circulating Tc17 cells and the serum levels of IL-17A and IL-23 in CRAⅠgroup and the early CRC group were respec-tively higher than those in CRAⅡgroup and the advanced CRC group (P<0.05), while the expressions of Treg cells was just the opposite , and no correlation between the expressions of Tc 17 and Treg cells was found (r=-0.227, P=0.073).Conclusion The changes in the percentage of Tc17 cells in peripheral blood are contrary to Treg cells in patients with CRA or CRC as the disease progresses , but there is no correlation be-tween them .

OBJECTIVEThis study aimed to detect the immunoexpression of interleukin-21 (IL-21) and receptor activator. of nuclear factor KB ligand (RANKL) in periapical granulomas (PGs) and radicular cysts (RCs). The interaction of IL-21 with RANKL and its role in periapical pathogenesis were also speculated.

METHODSA total of 32 PGs and 23 RCs were selected as experimental samples. Lesion size and occurrence of tenderness were recorded. Up to 10 healthy gingival tissues were collected as normal control samples. All tissues were subjected to immunohistocheincal analysis with anti-human IL-21 and RANKL polyclonal antibodies. The correlations of IL-21 with RANKL, lesion size, and the occurrence of tenderness of the PGs and RCs were evaluated.

RESULTSIL-21-positive cells were detected in all periapical lesion tissues but not in normal tissues. In the cyst group and granuloma group, the corresponding expression levels of IL-21 were 59.92±6.57 and 36.80± 6.81, whereas those of RANKL were 68.81±18.59 and 36.12±14.87, respectively. Moreover, t-test revealed a significantly higher expression of IL-21 and RANKL in RCs than in PGs (P<0.05). IL-21 and RANKL were positively correlated in both PGs and RCs (P<0.05). Furthermore, IL-21 was correlated with lesion size (P<0.05).

CONCLUSIONThis study demonstrated that IL-21 is potentially involved in the pathogenesis of apical periodontitis lesions. A role in the exacerbation of chronic inflammation, as well as in bone resorption, is suspected. Further studies are required to elucidate the specific functions of IL-21 in periradicular inflammatory processes.

Objective To compare ratio of circulating Th17 over Tc17 cells in patients with colorectal polyp (CRP), colorectal adenoma (CRA) and colorectal cancer (CRC),and analyse their relationship. Methods The ratio of circulating Th17 over Tc17 cells in 93 patients(17 CRP, 34 CRA and 42 CRC)and 17 healthy donors were examined by flow cytometry;Serum levels of IL-17A and IL-23 were tested by ELISA. Results The ratio of circulating Th17 over Tc17 cells and the se-rum levels of IL-17A and IL-23 were the lowest in healthy control groups, medium in CRP and CRA groups and the highest in CRC groups (P＜0.05). The proportions of Tc17 cells in CRA groups were significantly higher compared to those in CRP groups,but no statistical significance of proportion of circulating Th17 cells as well as serum levels of IL-17A and IL-23 be-tween CRA and CRP groups was observed (P>0.05). Further analysis showed that there was a positive correlation between proportions of circulating Th17 and Tc17 cells (rs=0.594, P＜0.001). Conclusion The proportions of circulating Th17 and Tc17 cells were positively related and the ratio of Th17 over Tc17 was markedly increased from CRP group or CRA group to CRC group.

Objective:To explore the changes and possible mechanisms of circulating Tc 17 cells in patients with colorectal cancer ( CRC) following disease progression .Methods:The peripheral blood were collected from 54 patients with colorectal cancer . the proportions of Tc17 cells in peripheral blood mononuclear cells (PBMCs) and cultured PBMCs treated by IL-1β, IL-6 and TGF-βin different concentrations were determined by flow cytometry;the levels of IL-1β, IL-17A, IL-23 and IL-6 in sera were measured by ELISA.Results:The proportions of Tc17 cells and the levels of IL-1β, IL-17A, IL-23 and IL-6 were significantly higher than those in healthy controls (P<0.05).Compared with early CRC, the proportions of Tc17 cells and the levels of IL-1β, IL-17A in advanced CRC were significantly decreased, but the level of IL-6 was significantly increased (P<0.05).The difference of IL-23 level between early and late groups was not significant (P>0.05).In vitro experiments confirmed that IL-1βor high concentrations of IL-6 and TGF-βcould significantly increase the number of Tc 17 cells in PBMCs.Conclusion: The changes of circulating Tc 17 cells in the progression of colorectal cancer are possibly modulated by IL-1β, IL-23, IL-6 and TGF-β.

OBJECTIVE:To provide reference for solving the shortage of national essential medicines in Changchun. METH-ODS:According to preliminary work,a questionnaire was conducted to investigate and statistically analyze the shortage situation of essential medicines in 22 higher than secondary and 50 basic medical and health institutions in Changchun;ABC analysis was used to analyze the national essential medicines in shortage;the bid results and shortage causes of the primary and secondary nation-al essential medicines in shortage were inquired. RESULTS:Totally 72 questionnaire were send out,and 72 were recycled with ef-fective recovery of 100%. The investigation results showed there were 19 shortage breeds(22 dosage forms),which lost the bid-ding,and 99 breeds(111 dosage forms)of national essential medicines in shortage,which won the bidding,including 85 kinds of chemical medicines and biological products,14 kinds of Chinese patent medicine in Changchun. Cardiovascular system drugs shows the largest number in the bid chemical medicines and biological products,and the Chinese patent medicine were mainly Fu-zheng agent and Quyu agent(internal medicine). Results of ABC analysis showed,among the 111 bid shortage dosage forms,17 were primary and 23 were secondary. The main causes for them were price raising in raw materials,lack of production,no produc-ing in manufacturers and purchase price higher than winning bids. CONCLUSIONS:Low accessibility of raw material drugs,low enthusiasm to production,lower drug price than a reasonable level,and small clinical requirements can lead to the shortage of na-tional essential medicines. It is suggested to intensify in supervising the raw materials’marketing,raising the enthusiasm of manu-facturers,perfecting the system of drug bidding,developing fixed-point production and building drug reserve system to guarantee the production and supply of national essential medicines,and satisfy clinical demands.
