Objective To analyze the clinical typing, pathological classisfication, and prognosis of primary IgA nephropathy (IgAN).Methods Clinical typing, pathological classisfication and relationship between clinical manifestations and pathological features of 220 cases with IgAN were analyzed in 10 years.Results IgA nephropathy occupied 42.9％ (220/512) of all the patients received renal biopsy at the corresponding time.Asymptomatic abnormal urinalysis was the most common clinical manifestation(39.0％ (86/ 220)), followed by hypertension (17.7％ (39/220)) and recurrent macroscopic hematuria (15.4％ (34/220)).Grade Ⅲ pathological change(29.5％ (65/220)) was the most co mmon,followed by grade Ⅱ (27.3％ (60/ 220)) and grade Ⅳ (18.2％), Grade Ⅰ/Ⅴ were relatively less ((11.4％ (25/220), 13.6％ (30/220)).No correlation could be found between types of deposited immune complex and pathological lesion extent(x2=4.87, P＞0.05).The clinical manifestations were significantly correlated with the severity of glomerular lesions (x2 =13.14,P＜0.05).During the follow-up for 106 patients (mean duration of 23 months), 90 patients(84.9％) had normal renal function and 75 patients(70.8％) had decreased excretion of protein in urine (＜1 g/24 h).Conclusion The clinical typing of primary IgA is correlated with pathological changes.The prognosis of IgA is markedly correlation with the pathological lesion degree.Renal functions will be improved if the different treatments were given according to the different renal pathological features.

The authors expound the idea and service priorities of terminal care, making it clear that pain control and emotional support of relatives after the death of the patient are the major content of terminal care at present. They suggest that nursing in terminal care be implemented according to the situation of our country. Firstly, institutions for terminal care need to be established. Secondly, education of patients, their relatives and medical workers themselves regarding death ought to be strengthened. Thirdly, training in knowledge and skills of consolation should be conducted among nurses. And fourthly, nurses should be encouraged to cultivate noble moral sentiments, enhance training in clinical skills, receive education in psychology, and master nursing skills in psychology so as to do a good job of terminal care.

AIM: To analyze the characteristics of internal fixation implantation therapy for comminuted patella fracture. METHODS: A computer-based search of Pubmed database and Chinese Journal Full-text Database was undertaken, and the quotations of each literature were checked after the primary screening. Inclusion criteria: the papers about the application of internal fixation materials in comminuted patella fracture, those published in authority journals within recent five years were preferred. Exclusion criteria: repeated study or Meta analysis. RESULTS: Internal fixation approach differs as the fracture type. Tension band fixation is generally accepted to treat transverse patella fracture. Kirschner wire plus tension band fixation are inferior to transverse fixation, but in comminuted fracture it can induce more complications; despite of wide application, nickel titanium patella fixator is unsuitable for comminuted fractures due to its hypersensibility and carcinogenicity; silk or steel wire loop fixation fits various comminuted fractures, but metal cerclage is predisposed to induce infection and breakage because of insufficient fixation force. CONCLUSION: There is no common way for comminuted patella fracture therapy. Further researches on material and method which can cure all kinds of comminuted patella fracture are still needed.

Objective To evaluate the effects and security of single or combined sufentanil application on sedation and analgesia for mechanically ventilated patients in intensive care unit(ICU).Method A total of 160 ICU patients with mechanical ventilation were randomly allocated into four groups:sufentanil group,sufentanil plus midazolam group,sufentanil plus dexmedetomidine group and fentanyl group.Facial pain scale(FPS),Ramsay score and vital signs were employed to assess the effects of different therapies on organ functions and adverse reactions.Result After the treatment,FPS in all groups were significantly decreased and maintained around 3 points.Ramsay scores were significantly increased(P <0.001)and the score in group given sufentanil combined with midazolam or dexmedetomidine at the time points of30 min,1 h,6 h were even higher.Compared with the preoperative data,indicators of lung function(PaCO2and blood lactic acid),liver function(AST)and renal function(Cr)were decreased in all groups(P <0.05).Respiratory rate in the fentanyl group was significantly higher than the others.Total consumption ofsufentanil in group with combined sufentanil application was significantly lower.No significant differencesin adverse reactions were noticed among the groups(P >0.05).Conclusion For mechanically ventilatedpatients,sufentanil has efficient sedative and analgesic effects with less physiological interference and severe adverse reactions.Combined application is beneficial in decreasing total sufentanil consumption andinhibition to respiratory system,which is worthy of being spread.

Objective To explore the quality control method of leucodepleted red cell concentrate (LDRC) preparation ,to choice an optimal processing , in order to raise the quality of LDRC,so as to ensure the efficiency and safty for the preparation application.Methods 62 bag red cells concentrates suspensin(each 150ml,preparation from 200ml whole blood) were investigated.By linear regression multianalyzed the effects of some factors on efficiency for removal of leukocytes from red cell concentrates.Free hemoglobin value(n=8) was detected before and after leukodepleted filtration.1% samples were tested and bacterial cultured,and observed the clinical adverse effects after LDRC tranfusion.Results ⑴The plasma and platelet in red cell contentrate before filtration,the time of filtration had influence significantly on the result of leukocyte depletion.⑵The percentage of leukodepleted red cell in which residual leukocyte less than 5?10 6/unit and 1?10 6/unit were 100% and 46.9%.

Objective Ouabain is a cardiotonic steroid that can induce the apoptosis of many tumorous cells .This study was to investigate the anti-tumor mechanisms of ouabain by observing its effects on the apoptosis of T lymphoblastic leukemia Jurkat cells and the expressions of hTERT and c-myc mRNA and protein . Methods Jurkat cells were treated with ouabain at the concentrations of 50 and 100 nmol/L for 24 and 48 hours, and those treated with 1 ×PBS served as the control .Then the apoptosis rate of the cells was detected by flow cytometry after Annexin V/PI staining, the expressions of hTERT and c-myc mRNA determined by RT-PCR, and those of hTERT and c-myc protein by Western blot . Results The apoptosis rates of the Jurkat cells in the 50 and 100 nmol/L oua-bain groups were (5.67 ±3.71)%and (9.63 ±4.83)%respectively at 24 hours, and (19.67 ±4.55)%and (37.60 ±11.89)%at 48 hours, significantly higher than (4.23 ±1.01)%in the PBS control group at 48 hours (P<0.05).Compared with the control, the expressions of hTERT and c-myc mRNA were decreased by 200%and those of hTERT and c-myc protein by 224%and 400%, re-spectively, at 48 hours (P<0.05).There was a positive correlation between the reduction of the mRNA levels and that of the protein levels of hTERT and c-myc (P<0.05). Conclusion Ouabain can down-regulate the mRNA and protein expressions of hTERT and c-myc, which may be one of the mechanisms of its induction of the apoptosis of Jurkat T lymphocyte leukemia cells .

Objective To study the diagnostic value of the morphological changes to deep fascia in distinguishing between benign and malignant soft-tissue tumors in lower limbs using 3.0 T MRI. Methods MR images of 40 consecutive patients with 41 pathologically proven soft-tissue tumors of the lower limbs were retrospectively reviewed by two radiologists. Lesions were divided into four groups according to their predominant location with respect to the deep fascia: (1)Subcutaneous lesions superficial to the deep fascia (n=7). (2) Lesions located beneath the deep fascia (n=8). (3) Lesions in the interspaces of the deep fascia investment (n=10). (4) Intramuscular lesions (n=16). The relationship between tumors and the deep fascia and the morphology changes of deep fascia were analyzed. Lesions of groups (1) (2) were considered as superficial lesions, while lesions of group (3) (4) were considered as deeper lesions. The size differences between those had intact deep fascia and those had destructed deep fascia in superficial lesions and in deeper lesions were evaluated by using Mann-Whitney U test, respectively. P values < 0. 05 were considered statistically significant. Results The deep fascial structures were intact in all of the 16 pathologically proven benign lesions. In 23 of the 25 malignant lesions, there was destruction of the deep fascia with the signs of displacement/disruption of the deep fascia and penetrating growth in (1) (2), and displacement/distruption of intermuscular septum as well as involvement of interspaces of the deep fascial investment and loss of integrity of the fascial/muscular planes in (3) (4). Only 2 malignant lesions demonstrate intact deep fascia. In superficial lesions [(1) (2)] , the maximum size were (5.0±3.8) cm (Median ± Interquartile Range) in those had intact deep fascia, and (5.7±6.90) cm in those had destruction signs (T=47.5, P >0.05). In deeper lesions [(3) (4)] the maximum size were (4.6±1.9) cm of those had intact deep fascia, and (13.6±6.5) cm of those had destruction signs (T= 62.5, P <0.01). Distinguish malignant from benign lesions on the signs of destructed deep fascia, the sensitivity, specificity and accuracy were 92.0% (23/25), 100% (16/16), and 95. 1% (39/,41), respectively. Conclusions Tumor involvements and disruption of the deep fascial structures visualized by 3.0 T MR imaging may be of utility in differentiating malignant from benign soft-tissue tumors.
