OBJECTIVEIn order to improve the irrigation for Panax notginseng growing seedlings, different mulching ways were carried out to investigate the effects of double mulching.

METHODField experiment was applied to study soil moisture, soil temperature and bulk density of different mulching ways while the germination rate and seedlings growth also were investigated.

RESULTCompared with the traditional single mulching with pine leaves or straw, double mulching using plastic film combined with pine leaves or straw could reduce 2/3 volumes of irrigation at the early seedling time Double mulching treatments didn't need to irrigate for 40 days from seeding to germination, and kept soil moisture and temperature steady at whole seedling time about 30% and 9.0-16.6 degrees C, respectively. The steady soil moisture and temperature benefited to resist late spring cold and germinate earlier while kept germination regularly, higher rate and seedlings quality. In contrast, single mulching using pine leaves or straw had poor soil moisture and temperature preserving, needed to irrigate every 12-day, meanwhile dropped the germination and booming time 14 days and 24-26 days, respectively, reduced germination rate about 11.3%-8.7%. However, single pine leaves mulching was better than straw mulching. In addition, though better effects of soil moisture and temperature preserving as well as earlier and higher rate of germination with single plastic films mulching had, some disadvantages had also been observed, such as daily soil temperature changed greatly, seedling bed soil hardened easily, more moss and weeds resulted difficulty in later management.

CONCLUSIONTo the purpose of saving water and labor as well as getting higher germination rate and seedlings quality, double mulching using plastic films combined pine leaves at the early time and single mulching removing plastic films at the later time is suggested to apply in the growing seedlings of P. notoginseng.

OBJECTIVETo explore the clinical efficacy of Gengxueting (GXT) in treating hysteromyoma and its effects on estrogen receptor (ER) and progesterone receptor (PR).

METHODSSixty-four hysteromyoma patients with surgical indication were equally assigned to the treated group and the control group. Patients in the treated group were treated with GXT one capsule every day for 90 consecutive days before surgical operation, while those in the control group were treated with surgery alone. Serum levels of reproductive hormones were determined in the follicular phase before medication and one day before operation by RIA, and colored Doppler ultrasound examination was conducted for measuring the size of uterus and myoma. Moreover the protein expressions of ER and PR in tumor and uterine muscular tissues were detected by immunohistochemistry assay with streptomycin avidin-biotin peroxidase complex method.

RESULTSIn the treated group after medication, the serum level of estradiol was (167.0 +/- 85.9) pmol/L, progesterone (1.9 +/- 1.0) nmol/L, follicle-stimulating hormone (10.4 +/- 2.1) IU/L, and luteinizing (12.0 +/- 9. 8) IU/L, all reached the levels of early follicular phase, with the maximal size of myoma significantly decreased from (380.4 +/- 21.0) cm3 to (162.3 +/- 14. 8) cm3 (P < 0.01); and the ER and PR expressions in tumor tissue were significantly lower than those in the control group respectively (P < 0.01).

CONCLUSIONExpressions of ER and PR in hysteromyoma tissue could be significantly reduced by medication of GXT, which leads to significant shrinkage of tumor size and improvement of clinical symptoms.

BACKGROUNDSensitization in transplant candidates increases risk of irreversible immunologic injury of graft in the early period postoperatively. Elimination of anti-human leukocyte antigen (HLA) antibodies using protein A immunoadsorption (IA) might benefit these patients.

METHODSProtein A IA was used in 21 patients with high panel reactive antibody (PRA). The patients had IA 1 - 6 times (median 5 times) with the interval period was 2 - 5 days (median 2.5 days).

RESULTSTotal 67 IA procedures were carried out smoothly in all patients. IA treatment reduced PRA I (pre (31.4 ± 3.8)% vs. post (24.4 ± 3.4)%, P < 0.01) and II (pre (37.1 ± 4.3)% vs. post (34.1 ± 3.9)%, P < 0.01). However, PRA did not change in some patients after the treatment. The serum immunoglobulin (IgG, IgM and IgA) and complement C3, C4 level were decreased significantly. Hemoglobin and albumin levels were slightly decreased associated with IA procedures. Flu-like symptoms were observed in a few of cases during the procedure but generally mild and transient.

CONCLUSIONProtein A IA is capable to efficiently remove serum immunoglobulin and complement, reduce HLA class I and class II PRA in high sensitized transplant candidates, which is likely to benefit the kidney transplantation in these patients.

To investigate and compare the expression of intercellular adhesion molecule-1 (ICAM-1) in different organs of the mice with endotoxic shock induced by lipopolysaccharide (LPS), protein and mRNA of ICAM-1 were measured by Western blotting and RT-PCR respectively in different organs of BALB/c mice administered intraperitoneally with 5 mg/kg LPS. The results showed that the constitutive expression of ICAM-1 protein and mRNA was the greatest in the lungs, followed by the spleen, kidney and intestine. After LPS stimulation, the upregulation of ICAM-1 was still greatest in the lungs, followed by the liver, spleen, heart, kidney and intestine. Compared with the normal mice, the expression of ICAM-1 protein in endotoxic shocked mice increased by 4.5-fold in the lungs, 3.0-fold in the kidney, 1.5-fold in the spleen; the expression in the liver and heart was negative under normal condition and changed into positive during endotoxic shock; but ICAM-1 expression in the intestine did not change significantly. The expression of ICAM-1 mRNA also increased consistently. These data highlight that LPS can up-regulate ICAM-1 protein and mRNA expression in different tissues of the mice with endotoxic shock. The difference in ICAM-1 expression among the organs may lead to different sensitivity of organ damage in endotoxic shock. This suggests that inhibition of ICAM-1 expression may be a useful principle for prevention and treatment of endotoxic shock.

OBJECTIVETo further study the binding character of hepatitis B surface antigen (HBsAg) and beta 2-glycoprotein I (beta2GP I) and to explore whether beta2GP I plays an important role in the hepatotropism of hepatitis B virus.

METHODSUsing Western blot technique, we observed the binding character of the HBsAg with reduced and non-reduced beta2GP I.

RESULTSrHBsAgs with reduced and non-reduced beta2GP I showed identical binding activity.

CONCLUSIONSThe binding activity of HBsAg is dependent on tandem residues, but not on conformational structures of beta2GP I. There is a specific binding between HBV and beta2GP I, which may play an important role in HBV infection and is one of the reasons of hepatotropism of HBV.

OBJECTIVETo report a case of primary peripheral T-cell lymphoma of the penis.

METHODSWe analyzed the clinicopathological characteristics of the case of primary peripheral T-cell lymphoma using histological, cytochemical and immunohistochemical methods and by review of the literature.

RESULTSThe patient was a 65 years old man and presented with a diffuse enlargement of the penis as the initial sign, followed by erosive ulcer in the caput penis and inguinal lymphadenectasis. The tumor was pathohistologically manifested as an epidermal ulcer, with tumorous necrosis around the capillary, infiltrative growth and atypical changes of the neoplastic cells and proliferation of capillaries. Immunohistochemically, the tumor cells were positive for CD43 and CD3, but negative for CD20, CD79a, CD34, CD30, CD56 and CD34. Clinically it responded to the chemotherapy designed for peripheral T-cell lymphoma.

CONCLUSIONPrimary peripheral T-cell lymphoma of the penis is an extremely rare malignant tumor, the diagnosis of which relies on histopathological examination, immunohistochemical staining and differentiation between squamous cell carcinoma and other types of lymphoma.

OBJECTIVETo investigate the efficacy and safety of gastrointestinal pacemaker in treatment of gastric dynamic disorders.

METHODSSixty patients with more than two symptoms as postprandial fullness, epigastric pain,epigastric fullness, belch, nausea, hypercoria,anorexia,vomiting and at least for twelve weeks were divided into three groups randomly. Thirty patients were treated with gastrointestinal pacemaker for ten days(pace maker group); fifteen patients were treated with gastrointestinal placebo machine for ten days (control group); fifteen patients received treatment with cisapride 5 mg three times daily, thirty minutes before meal (cisapride group) for ten days. Electrogastrogram(EGG) was performed on before and after treatments, the mean frequency and mean amplitude of EGG, the clinical symptoms and adverse reactions were observed.

RESULTSTotal efficacy of pace maker group, control group and cisapride group was 90.0%, 46.6% and 86.7%, respectively. The score of symptoms was significantly decreased after treatment with gastrointestinal pacemaker and cisapride (P<0.05). Before and after meal EGG exam showed that average frequency was reversed to normal level after treatment with gastrointestinal pacemaker.

CONCLUSIONGastrointestinal pacemaking can relieve symptoms and improve the average frequency of EGG in patients with gastric dynamic disorders.
