Objective To detect and analyze nuclear factor kappa B (NF-κB),Helicobacter pylori (HP),Helicobacter pylori cytotoxin associated protein A (CagA),platelet (PLT) and platelet associated IgG (PA IgG) in 224 patients with idiopathic thrombocytopenic purpur(ITP) from three urban hospitals of Shaoxing,in order to explore the role of NF-κB and CagA in the pathogenesis of ITP,then to improve the prognosis of ITP.Methods SABC method was used to detect the NF-κB,13C breath test for the determination of the Hp infection.CagA and PA-IgG were tested by enzyme linked immunosorbent assay.Automatic blood cell analyzer was used to measure PLT.According to the test results,the patients were divided into Hp+cagA+NF-κB+,Hp+cagA+NF-κB-,Hp+cagA-NF-κB+,Hp+cagA-NF-κB-,Hp-NF-κB+,Hp-NF-κB-PLT groups,and PA-IgG,PLT of the six groups were statistically analyzed.Results Of 224 cases with ITP,175 cases of HP positive,the positive rate was 78.13%.CagA+ 91 cases in 175 cases of Hp+,accounting for 52%,overall 43.63%.NF-kappa B+ 108 cases,the positive rate was 46.21%,78 cases were found in Hp+cagA+,accounting for 85.71% in cagA+.In 84 cases of Hp+cagA-,there were 21 cases NF-κB+,the positive rate was 25%.In 49 of HP-,9 cases with NF-kappa B+,accounting for 18.37%.PLT and PA-IgG were compared among the groups.The count of PLT of group Hp+,group Hp+cagA+ and group NF-κB+ was lower than group Hp-,group Hp+cagA- and group NF-κB-.However,the level of PA-IgG of group Hp+,group Hp+cagA+ and group NF-κB+ was higher than group Hp-,group Hp+cagA- and group NF-κB-,the difference was statistically significant(P<0.05).Conclusion CagA maybe directly or through the activation of NF-kappa B take part in the immune response of ITP,cause PA-IgG increased and thrombocytopenia.

The patient,a 11-year-old boy,presented with a 4-year history of erythema and vesicles on the face and arms as well as a 4-month history of tumor and ulcer on the extremities,accompanied by progressive fatigue and intermittent fever.The patient had a body temperature of 37.7℃.No lymph node involvement was observed.Cutaneous examination revealed minimally indurated pink-red patches on the face and nose and dusky red firm nodules and tumors of varying sizes on the extremities.The nodules ranged from 2.0 cm to 18 cm in diameter,some had necrosis and black crusts on the surface.Ulcers were observed in some of the larger nodules;many of the ulcers extended into the muscle layer.White purulent discharge was seen on the surface of many of the nodules.The lesions were sharply demarcated,firm,tender, and surrounded by small satelite nodules.Histologically,there were large quantities of irregularly shaped, middle-sized tumor cells with clear cytoplasm,large twisted nuclei and prominent chromatin,infiltrating from the epidermis to subcutaneous tissue.The tumor cells infiltrating the follicles and eccrine sweat glands were either distributed perivascularly in a nest shape,or dispersed.There were broken nuclei and reactive histio- cytic infiltration in the dermis and subcutaneous tissue.Immunohistologically,the tumor cells were positive for cytoplasmic CD3 around the nuclei,for CD56,CD45RO and T cell intracellular antigen-l,and partly for CD30,CD8 and Ki67.Epstein-Barr virus-encoded nuclear RNA was positive with in situ hybridization. TCR?-2 gene rearrangement was positive in these tumor cells.A diagnosis of hydroa vacciniforme-like primary cutaneous NK/T-cell lymphoma was made.Therefore,this is a case report of hydroa vaccini- forme-like primary cutaneous NK/T-cell lymphoma with primary involvement in the skin;the condition was slowly progressive over 51 months.

A reasonable and practicable quality standard was developed for mori liquid extract from different sources by TLC, HPLC and fingerprint technology. In TLC method, the compounds were separated on polyamide film using glacial acetic acid-water (1: 3) as mobile phase at a UV wavelength of 365 nm. All qualified samples had the spots of the same color as the control herb and substance. The RP-HPLC method was used to determine the content of mulberroside A with mobile phase of methanol-water (25: 75) at a wave-length of 326 nm. The mulberroside A was in good linear with a regression equation of Y = 46.965X (r = 0.999 6) in the range of 4.6 - 228 mg x L(-1). In 14 batches of samples, the mulberroside A in 4 batches of them was less than 0.5 g x L(-1), and was more than 2.0 g x L(-1) in the other batches. It was suggested that the content limit of mulberroside A should be no less than 1.5 g x L(-1). The HPLC fingerprints were evaluated by the similarities. It has found that the similarities of different mori liquid extracts were very low and the chemical diversity of mori cortex was the major factor of similarity. Moreover, the process impact was minimal. Thus the fingerprint was not included in this quality standard.

OBJECTIVETo explore the effect of Bushen Tiaojing Recipe (BTR) on the quality of oocytes, reproductive hormones, and the expression of bone morphogenetic protein-15 (BMP15) of in vitro fertilization-embryo transfer (IVF-ET) patients.

METHODSSixty infertility patients who prepared for IVF-ET were assigned to two groups according to the treatment order, the treatment group [20 cases, treated with BTR + controlled ovarian hyperstimulation (COH)] and the control group (treated with COH alone, 40 cases). Age, the time limit for infertility, basal follicle-stimulating hormone (bFSH) concentration, usage days and the dosage of gonadotropins (Gn), serum levels of estradiol (E2), luteotropic hormone (LH), and progesterone (P) on the HCG injection day, the number of retrieved occytes, the fertilization rate, the number of embryos, the high quality embryo rate, and the clinical pregnancy rate were compared. Concentrations of follicle-stimulating hormone (FSH), LH, E2, testosterone (T), and P in the follicular fluid were detected via chemiluminescence microparticle immunoassay. The mRNA and protein expression of BMP-15 in mature granulosa cells was detected by real-time fluorescent PCR and Western blot.

RESULTSThirty-two patients were pregnant and the total pregnancy rate was 53.3%. Of them, 19 were pregnant and the total pregnancy rate was 47.5% in the control group, while 20 were pregnant and the total pregnancy rate was 65.0% in the treatment group. But there was no statistical difference between the two groups (P > 0.05). Compared with the control group, the Gn dosage was lower and the high quality embryo rate was higher in the treatment group, showing statistical difference (P < 0.05). There was no statistical difference in serum concentrations of E2, LH, or P on the HCG injection day, the number of retrieved oocytes, or the fertilization rate (P > 0.05). Compared with the control group, FSH concentrations in the follicular fluid were significantly lower and LH concentrations were significantly higher in the treatment group (P < 0.05). The LH concentrations in the follicular fluid were significantly higher in pregnant patients than non-pregnant patients, showing statistical difference (P < 0.05).There was no statistical difference in E2, T, or P concentrations (P > 0.05). The mRNA and protein expression of BMP-15 in granulosa cells was higher in the treatment group than in the control group (P < 0.05). It was also higher in pregnant patients than non-pregnant patients, showing statistical difference (P < 0.05).

CONCLUSIONDuring the IVF-ET process, BTR could elevate the quality of oocytes, and increase the sensitivity of ovarian follicles to exogenous Gn, which was correlated with the mRNA and protein expression of BMP-15 in granulosa cells, and changing concentrations of FSH and LH.

Objective To investigate the relation between the cellular immune function and unexplained recurrent spontaneous abortion(URSA) and the mechanism of active immunotherapy on URSA patients.Methods The flow cytometry(FCM) was used to detect CD3+ ,CD4+ ,CD8+ T lymphocyte and CD16+CD56+ natural killer(NK) cell subsets and the ratio of CD4+/CD8+ of peripheral blood(PBL).112 cases with URSA(76 cases treated with active immunotherapy) and 30 cases of normal fertiled(NF) women were studied.The percentages of T lymphocyte and NK cell subsets before and after therapy were compared among 76 cases wtih URSA treated by active immunotherapy.The rate of next successful pregnancy of URSA patients treated with and without active immunotherapy was compared.Results The percentages of CD3+ and CD16+CD56+ cell subsets as well as the ratio of CD4+/CD8+ of the URSA patients were significantly higher than those of NF cases(P <0.05).After active immunotherapy,the percentages of CD3+ and CD56+CD16+ cell subsets as well as the ratio of CD4+/CD8+ of URSA cases were significantly decreased(P <0.05 ).The rate of next successful pregnancy of URSA cases with and without active immunotherapy were 88.2% and 31.2% respectively,the difference was significant(P< 0.05).Conclusion The changes in the percentages of T lympyocyte and NK cell subsets have something to do with URSA.Active immunotherapy can effectively regulate the cellular immune function and increase the rate of next successful pregnancy of URSA patients.

OBJECTIVETo study the effect of gradually induced occlusal disorders on the expression of basic fibroblast growth factor (bFGF) of condylar cartilage in rat.

METHODSThe model of gradually induced occlusal disorders was established in rat. The expression of bFGF was examined by SABC technique of immunohistochemistry. The expression of bFGF was analyzed by amount of positive cells.

RESULTSbFGF was expressed positively in the proliferative cell layer, maturative layer and hypertrophical cell layer in the rat mandibular condyle cartilage. In control group, expression of bFGF increased from 2-week-old to 6-week-old, then it had a decrease during experiment. Compared with the control group, bFGF of experiment group was increasing at 2 week, 6 week and 8 week during experiment. But there was decreaseing at 4 week. There was no difference between young experiment group and the adult experiment group.

CONCLUSIONThe gradually induced occlusal disorders may lead to significant increase of expressiong of bFGF in condyle cartilage, which suggests that the bFGF may be involve in the procedure of repairing process of articular cartilage.

OBJECTIVEThis article was to study the effect of induced occlusal disorders and removed occlusal disorders on the expression of bone morphogenetic protein-2 (BMP-2) of condylar cartilage.

METHODSYoung and adult female Sprague-Dawley rats were divided respectively into induced occlusal disorders group, removed occlusal disorders group and control group, 3 rats every group. For induced occlusal disorders rats, the elastic rubbers were inserted between the first and second molar in the left upper side and right lower side to form the disordered occlusion. They were killed under anaesthesia 8 weeks after the treatment. For removed occlusal disorders rats, the first molars that caused disordered occlusion were extracted 6 weeks after forming disordered occlusion. 2 weeks later, they were killed under anaesthesia. For normal rats, they were killed at the same time with experimental rats. Hibateral temporomandibular joints of each rat were removed and stained with HE and monoclone antibody of BMP-2. The thickness of condylar cartilage was measured. The expression of BMP-2 in condylar cartilage was detected by half-quantity immunohistochemical analysis.

RESULTSFor adult induced occlusal disorders group, the thickness of cartilage in intermediate part of condyle decreased. However, it increased in the posterior part. After removing occlusal disorders, the thickness of posterior condylar cartilage returned to normal level. But it was still thinner than control group in the intermediate part. The expression of BMP-2 in anterior, intermediate, posterior part of condylar cartilage of young induced occlusal disorders group was higher than that of young removed occlusal disorders group expression of BMP-2 showed induced occlusal disorders group was higher than removed occlusal disorders group, which was higher than control group. and control group. No difference of the expression of BMP-2 was found in young removed occlusal disorders group and control group. For the expression of BMP-2 in intermediate part of condylar cartilage, both adult induced and removed occlusal disorders groups were higher than adult control group. For the posterior part of adult condyle cartilage, the expression of BMP-2 showed induced occlusal disorders group was higher than removed occlusal disorders group, which was higher than control group.

CONCLUSIONInduced occlusal disorders can lead higher expression of BMP-2 in condylar cartilage of young and adult rats. Adaptability of condylar cartilage of adult rats is weaker than young rats, especially the intermediate part.
