Objective To identify the clinical characteristics and pathological changes of patients suffered from glomerulonephritis complicating with acute interstitial nephritis (AIN) . Methods Twenty one patients of glomerulonephritis complicating with AIN diagnosed by renal biopsy were retrospectively analyzed . Thirty-five pure AIN patients were selected as controls .Results Glomerulonephritis complicating AIN accounted for 37 .5% of all the AIN cases . Βlactam antibiotics and Chinese herbs were the major causes of AIN . 76 .2% of cases received further examinations due to the elevation of serum creatinine (Scr) during their follow-up of kidney injuries or during routine exams for all kinds of discomforts . Pathological features of AIN were also detected besides glomerular leisions . The impairments of renal interstitia were severe than those of the glomeruli . Eosinophil in the renal interstitia was an important indicator for the diagnosis of AIN .The renal function returned to normal or baseline in 64 .7% of the patients of glomerulonephritis complicating with AIN whose follow-up data were available . The median period for renal function restoration was 150 days (compared with 60 days in pure AIN) . But there were no significant differences between these two groups as for the rate of irreversible renal insufficiency during a follow-up period of 2 years . Conclusions Symptoms of AIN in patients of glomerulonephritis complicating with AIN tend to be masked by their glomerular diseases . Renal biopsy is of most importance for the diagnosis . Early diagnosis and treatment leads to satisfactory prognosis .

The DNA structures could be altered or even damaged by exogeous or endogenous factors during cell proliferation. Failure of effective and timely repair will lead to cell cycle arrest or apoptosis. By taking the advantage of the quick proliferation of cancer cells, DNA damage induction, cell cycle arrest and apoptosis promotion have become important strategies for ant-cancer chemotherapy. Previous reports showed that an array of natural compounds inhibit cancer cell proliferation by inducing DNA damage, which have therapeutic potentials for anti-cancer drug research and development.

In this article, the research of chemical constituents and bioactivities in recent ten years has been reviewed of plants from the 12 genera in Flacourtiaceae related to the medicinal resources in China. The research in China about the plants from Flacourtiaceae was done very little, but many literatures have been reported abroad. The plants from Flacourtiaceae mostly contain the constituents such as aromatic glucosides, lignanoid glucosides, diterpenoids and cyclopentenoid cyanohydrin glucosides et al. These compounds or plant extracts mainly show antibacterial, antiviral, antitumor, hypolipidemic and hypoglycemic activities. The research of plants from Carrierea, Itoa and Bennettiodendron of Flacourtiaceae in China is still blank. The systemic research about chemical constituents and bioactivities of plants from these genera will play important roles in the discovery of novel natural products and active constituents, and provide valuable reference for the classifying of plants from these genera.

In order to investigate whether cytokine-induced killer (CIK) cells can induce apoptosis of bcr-abl(+) K562 cells, apoptosis of K562 cells and CEM cells induced by CIK cells, etoposide or camptothecin was detected with flow cytometry DNA assay. RT-PCR showed that K562 cells expressed the bcr-abl fusion gene, K 562 cells, K562 cells/etoposide or K562 cells/camptothecin groups showed no sub-G(1) peak. K562 cells/CIK cells group showed sub-G(1) peak (38.1%). CEM cells showed no sub-G(1) peak. CEM cells/camptothecin or CEM cells/etoposide groups showed sub-G(1) peak (23.5% or 32.3% respectively). CEM cells/CIK cells group showed sub-G(1) peak (45.4%). Etoposide or camptothecin did not induce apoptosis of K562 cells. CIK cells induce apoptosis of K562 cells. Bcr-abl fusion gene prevented apoptosis induced by etoposide or camptothecin, but did not prevent apoptosis induced by CIK cells. This property may support the observed adoptive immunologic effect of allogeneic bone marrow transplantation and donor lymphocyte transfusions of CML case relapsing after allogeneic bone marrow transplantation.

OBJECTIVETo investigate the value of fractional nitric oxide concentration in exhaled breath (FeNO) in assessing the level of asthma control in children.

METHODSA total of 226 asthmatic children were divided into controlled asthma (n= 86), partially controlled asthma (n=63), and uncontrolled asthma groups (n=77). Ninety healthy children were enrolled as controls. FeNO was measured for both asthmatic and healthy children using the Swedish-designed NIOX system.

RESULTSThe control group had an FeNO of 14±6 ppb, the controlled asthma group had an FeNO of 29±26 ppb, the partially controlled asthma group had an FeNO of 32±30 ppb, and the uncontrolled asthma group had an FeNO of 40±32 ppb. The three asthma groups showed significantly higher FeNO than the control group (P<0.05). The uncontrolled asthma group showed significantly higher FeNO than the controlled asthma group (P<0.05), but there were no significant differences in FeNO between the partially controlled and uncontrolled asthma groups and between the partially controlled and controlled asthma groups (P>0.05).

CONCLUSIONSAsthmatic children have significantly higher FeNO than healthy children, and FeNO is correlated with the level of asthma control.

OBJECTIVETo study the effects of Wenyang Shengjing Decoction (WSD) containing serum on the estradiol (E2) secretion, the synthesized cytochrome P450 aromatase (P450arom) activities, as well as the expression of its encode gene CYP19 in Leydig cells of male sterile rats of adenine induced Shen-yang deficiency (SYD).

METHODSExperimental rats were randomly divided into 4 groups, i.e., the normal control group, the high, middle, and low dose WSD groups, 5 in each group. The normal saline, low, middle, and high dose WSD were respectively given to rats of all groups for 10 successive days. Blood was drawn from rats' heart 2 h after the last gastrogavage. The serum was separated after centrifuge. Leydig cells isolated and purified from SYD rats were primary cultured in vitro and divided into 5 groups in random, i. e., the blank control group, the model group, the high, middle, and low dose WSD groups (1.2, 1.0, and 0.8 g/mL, respectively). The content of E2 released in the culture supernate was determined by radioimmunoassay. The P450arom activity was detected by tritium release assay. Meanwhile, the mRNA and protein expressions of CYP19 were analyzed using fluorescent quantitative PCR and Western blot respectively.

RESULTSCompared with the blank control group, the E2 secretion of the supernate of Leydig cells obviously decreased in the model groups, accompanied with the inhibition of P450arom activities, significant decreased protein and mRNA expressions of CYP19 (P < 0.01, P < 0.05). Compared with the model group, after intervened by WSD containing serum, the E2 secretion in the Leydig cells could be significantly increased, the P450arom activities up-regulated, the CYP19 expressions up-regulated at the protein and mRNA levels partially in a dose-dependent manner (P < 0.01, P < 0.05).

CONCLUSIONSWSD containing serum could effectively elevate the E2 secretion in Leydig cells, which might be partially achieved through up-regulating P450arom activities and enhancing the gene expression of CyP19. This might be one of its mechanisms of action for treating male infertility of SYD.

Objective To explore the effects of continuing nursing health education on postoperative rehabilitation of patients with gastric cancer. Methods A total of 98 cases of patients with gastric cancer radical were selected from December 2011 to December 2012 in our hospital according to the random number table method and were divided into observation group and control group. The patients of control group were given routine nursing, while the patients of observation group were given continuity of nursing health education based on the control group. We evaluated self satisfaction after nursing intervention of pain control, and assessed the score of self-rating anxiety scale ( SAS) , self-rating depression scale ( SDS) and quality of life self-rating scale. Results After intervention in the intervention group, the patients′ satisfaction to pain control method, to pain control education and all care, and family satisfaction scores were (42. 15 ± 14. 21), (44. 26 ± 13. 2), (16.69 ±2.20), that all were higher than these of the control group (t=3. 658, 5. 698, 4. 265; P<0. 05). Before the implementation of continuity of nursing health education, two groups of patients with SAS scores and SDS scores and the patient′s appetite, sleep quality and mental status, level of understanding of cancer, family understanding and cooperation, and daily life six dimensions related to the pain and psychological differences had no statistical significance (P>0. 05);continuity of nursing health education after implementation, the SAS scores and SDS scores were (30. 58 ± 8. 64), (35. 21 ± 9. 02) in the observation group that all were obviously lower than these of the control group (t=2. 245, 2. 014;P<0. 05); after the intervention group in appetite, sleep quality and mental status, the understanding of cancer, family understanding and cooperation, the score in the daily life were (3. 52 ± 0. 78), (4. 36 ± 1. 25), (3. 92 ± 1. 14), (4. 25 ± 0. 42), (3. 78 ± 0. 87), (4. 21 ± 0. 62);in six dimensions, related to the pain and psychological in the observation group were better than those of the control group (t=3. 145, 2. 896, 3. 859, 5. 697, 4. 021, 4. 256; P<0. 05). Conclusions Continuity nursing health education can reduce gastric cancer patients with postoperative pain and the degree of anxiety and depression patients, improve the patient′s quality of life and is good for stomach cancer patients with postoperative recovery.

This study was purposed to investigate the expression of c-fes gene in leukemia patients and its clinical significance. The expression of c-fes mRNA in bone marrow cells from 121 cases of acute and chronic leukemia patients, and the expression of c-fes mRNA in peripheral blood mononuclear cells of 20 normal persons were detected by real time-quantitative reverse transcription polymerase chain reaction (RQ-PCR). The results showed that the level of c-fes mRNA in AML patients was higher than that in normal controls [(48.017 +/- 57.170) x 10(-3) vs (0.152 +/- 0.398) x 10(-3)] (p < 0.0001); but there was no significant differences of level of c-fes mRNA between samples of ALL and normal controls(0.047 +/- 0.068) x 10(-3) vs(0.152 +/- 0.398) x 10(-3) (p>0.05); the level of c-fes mRNA in CML patients was higher than that in normal persons (21.605 +/- 24.818) x 10(-3) vs (0.152 +/- 0.398) x 10(-3) (p < 0.0001). The positive expression rate of c-fes gene in CML-CP patients (80%) was higher than that in CML-AP patients (66.7%) and CML-BP (28.6%) patients. In AML patients, c-fes gene was expressed higher in M(2) (80.77%) and M(3) (92.86%) patients. The remission rate of AML (except M(3))patients who had expression of c-fes gene was 81.08%, which was higher than that of patients with no expression of c-fes gene (40.00%). It is concluded that c-fes gene expression was found in myeloid leukemias, whereas low or no expression in lymphocytic leukemias. The differentiation of myelocytic cells may be related to c-fes gene. All AML (except M(3))patients with high level of c-fes mRNA may get good prognosis.
