The reproduction of Helicoverpa armigera nucleopolyhedrovirus in the midgut epithelia cells and the other sensitive tissues was observed by electron microscopy. The reproducing viruses in the midgut epithelia cells were mostly without envelopes, and thte polyhedrons were seldom formed. The reproduciing viruses in the other sensitive cells were with envelopes, and packed in polyhedrons.

Objective To study the changes of serum protein spectrum in patients with systematic lupus erythematosus (SLE) in order to screen specific protein markers. Methods Serum samples from 72 patients with SLE and 85 age- and sex-matched controls were assessed using surface-enhanced laser desorp-tion/ionization time-of-flight mass spectrometry (SELDI-TOF-MS) with weak cation exchange (CM10) pro-rein chip. Forty samples from the patients and 50 control samples were randomly selected to serve as a pre-liminary training set; significantly different protein peaks were automatically chosen for the system training and development of a decision classification tree model. The validity of the model was then challenged with a blind test set (including another 32 samples from patients and 35 from human controls). Results A total of 73 effective protein peaks were detected within the mass/charge ratio (m/z) interval 2000 - 50000, among which, 15 protein peaks significantly differed between patients with SLE and controls (P < 0.01). Three pro-tein peaks with an m/z value of 4001, 6305 and 7356 were automatically chosen as a biomarker pattern in the training set that discriminated patients with SLE from controls with a sensitivity of 90.0% (36/40), speci-ficity of 92.0% (46/50) and accuracy rate of 91.1% (82/90). When the SELDI marker pattern was tested with the blinded test set, it yielded a sensitivity of 87.5% (28/32), specificity of 91.4% (32/35) and accuracy rate of 89.6% (60/67). Conclusions SELDI-TOF-MS protein chip could be used to screen serum protein for SLE, and the decision classification tree model with these biomarkers may favor the diagnosis of SLE.

Objective To investigate effects of Kanglaite injection on proliferation, cycle and apoptosis of human breast cancer MCF-7 cells;To discuss its relevant mechanism. Methods Logarithmic growth phase cells were divided into control group and Kanglaite-treatment group (10, 20, 40μL/mL). Cells were cultured in RPMI-1640 for 24 h before drug treatment. The inhibition rate of Kanglaite injection on proliferation of human breast cancer MCF-7 cells was detected by MTT assay. Apoptosis and cell cycle of MCF-7 cells were detected by flow cytometry. Changes in cell nucleus were determined by Hochest staining assay. Protein expressions of Bcl-2 and Bax were detected by ELISA and Western blot. Results Kanglaite injection for 12 h, 24 h or 48 h resulted in a significant inhibition of MCF-7 cells proliferation (P<0.05, P<0.01);Compared with the control group, Kanglaite injection-treated cells showed increased percentage in G2/M and G0/G1 phases (P<0.001, P<0.01), but showed decreased percentage in S phase (P<0.01), and apoptosis rate increased (P<0.05, P<0.001). Kanglaite injection significantly decreased protein expression of Bcl-2, and enhanced protein expression of Bax of MCF-7 cells (P<0.01, P<0.001). Conclusion Kanglaite injection can inhibit the proliferation of human breast cancer MCF-7 cells, decrease cell cycle and induce apoptosis, the mechanism is related with decreasing protein expression of Bcl-2 and enhance the protein expression of Bax.

Aim To observe the effect of extracts of ginkgo biloba leaves(GbE) on platelet adhesion and thrombosis. Methods The platelet adhesion was assayed by rotating glass-globe method. The thrombogenesis method in artery-vein bypass was applied to observe thrombosis in vivo. The Chandler method was applied to induce thrombosis in vitro.The tail bleeding time was recorded by shearing tail method.Results GbE significantly decreased platelet adherence rate in rabbits, decreased the weight of thrombus produced in artery-vein bypass in rabbits, shortened the length and reduced dry weight of thrombus of rats in vitro,prolonged the tail bleeding time in mice.Conclusion GbE inhibits the platelet adhesion and thrombosis.

Objective To investigate the influences of Angiotensin II inhibitor on renal expression of HIF-1α mRNA and protein in the chronic renal failure (CRF) rats (induced by 5/6th kidney ablation/infarction \[5/6A/I\]) and the related mechanism. Methods SD rats were made into CRF model by means of 5/6th kidney ablation/infarction. The study was divided into sham operation group (Group A), model group (Group B) and Angiotensin II inhibitor(Cozaar-with-Monopril) group (Group C), each group containing 15 rats. The biochemical parameters of the rats were examined 60 days later in the 3 groups. The expression of HIF-1α mRNA and protein in the remnant renal cortex and medulla were assessed by Real-time PCR and Western blotting analysis. Results Compared with group A, group B had significantly increased SCr and BUN levels and significantly decreased CCr level(P<0.01). Compared with group B, group C had significantly decreased SCr and BUN levels and significantly increased CCr level(P<0.05). The expression of HIF-1α mRNA and protein in the renal cortex and medulla in group B was significantly higher than that in group A(P<0.05), and that in group C was significantly lower than that in group B (P<0.05). Conclusion Angiotensin II inhibitor can improve the renal function in CRF rats induced by 5/6(A/I), which might be associated with HIF-1α signaling pathway.

Objective To analyze the clinical and pathological characteristics of thyroid nodules.Methods A retrospective analysis of the clinical data of 2843 Han patients with thyroid nodules from January 2009 to June 2011 in Henan province was performed.Results The most high-risk of thyroid nodule resided in the group aged 45-54.The main pathological manifestation was simple nodular goiter.The rate of preoperative misdiagnosis was 2.4％.22.1％ of the patients with thyroid nodules showed abnormal thyroid function,which was mainly as subclinical thyroid dysfunction.The positive rate of thyroid peroxidase antibody (TPOAb) in patients with thyroid nodule was 19.8％ while that of thyroid globulin antibody (TgAb) was 20.0％.Among all 2843 subjects,the prevalence of differentiated thyroid carcinoma (DTC) was 28.8％,and the incidence of DTC was accompanied by raised TSH levels.The prevalence of DTC exceeded 40％ in patients aged between 25 to 34 as well as more than 74 years old.The prevalence of DTC was up to 33.8％ in TgAb positive patients.There was no difference in TPOAb levels between DTC patients and non DTC patients (P =0.406),but the TgAb level in patients with DTC was significantly higher than that of non DTC patients (P =0.033).Conclusion Thyroid nodule patients aged 25-34 or older than 74 formed high-risk groups of DTC.The serum TSH level and TgAb level were positively correlated with the risk of DTC.

Objective To review the clinical features,etiology and differential diagnosis of hypopituitarism.Methods The clinical data of 260 patients with hypopituitarism admitted to our hospital during 2007 to 2011 were retrospectively analyzed.Results In 260 patients 96 were males and 164 were females,the average age of female patients was significantly higher than that of males[ (44 ± 16) vs.(32 ± 20) years; t =3.821,P =0.001 ].Patients under 20 years accounted for the highest proportion in male cases (38/96,39.6％) ; while patients aged 40 - 60 years were the highest proportion for female cases (86/164,52.4％).Pituitary tumor and postoperative damage was the most common cause for hypopituitarism accounting for 36.2％ (94/260),followed by Sheehan syndrome (86/260,33.1％).The most common manifestation of hypopituitarism was anemia (102 eases) ; 26 cases presented all pituitary function failure.The causes leading to hypopituitarism usually showed specific manifestations in imaging examinations.The overall misdiagnosis rate was 40.4％ (105/260)in this series,while that of etiological diagnosis was 25.4％ (66/260).Conclusions This study suggests that hypopituitarism caused by different causes can be diagnosed by disease history,clinical manifestations and pituitary imaging examination.

Objective To assess the efficacy of methylprednisolone (MP)pulse therapy in treatment of Hashimoto thyroiditis(HT) complicated with goiter.Methods 30 patients with HT complicated with goiter participated in the study and received MP pulse therapy.The patients had to be euthyroid for at least 3 months before the date of inclusion with plasma concentrations of thyroid hormones within their reference range.The goiter was still obvious and had no improvement.A dose of 250 mg MP was administered intravenously for seven consecutive days,and then treated with oral prednisone 10 mg,three times per day for 6 weeks with the dosage in each week gradually reduced at 5 mg to none.Ultrasonic was used to measure thyroid size before and after MP treatment.Results The treatment was successful at the end of the trial in all of the 30 patients receiving MP.The thyroid size from length,breadth,thickness to isthmus obviously decreased (P ＜ 0.05).The length of the left lobe was (57.42 ± 12.87) mm and (46.37 ± 7.67) mm (t =4.58) before and after treatment; The breadth of the left lobe was(26.68 ±7.71) mm and(22.21 ±6.09) mm(t =4.56) before and after treatment; The thickness of the left lobe was (27.18 ± 6.60) mm and (21.14 ± 5.67) mm(t =7.28) before and after treatment.The length of the right lobe was(58.17 ± 12.32)mm and(49.73 ±9.35) mm(t =3.84) before and after treatment; The breadth of the right lobe was (26.14 ± 7.37)mm and (23.00 ± 6.68) mm(t =3.29) before and after treatment ; The thickness of the right lobe was(27.57 ± 6.42)mm and(22.00 ±5.55)(t =5.88)before and after treatment.The isthmus before and after treatment was(9.94 ±4.15)mm and(6.19 ±2.57)mm(t =6.09).The recurrence rate was 17％ (5/30) after one year.Conclusions MP pulse therapy is an effective treatment for HT complicated with goiter.The recurrence rate is low.
