To understand the adverse drug reaction (ADR) induced by Mailuoning injection. 162 ADRs due to the drug were retrieved from national medical journals of 1988-2007 for statistics. It was shown that there was no relationship between ADR and dosage, but ADR appeared mostly in middle-aged and old groups, and more in male than in female. The occurrence of ADR was commonly within 30 min after injection. It involved injuries of various systems and organs. As for the 123 cases of allergy, 38 were anaphylactic shock (accounting for 23.46%), two people died. ADR characterized by immediate type on initial use and tachy type. It should be paid more attention to the Mailuoning injection for the immediate hypersensitivity reaction (such as anaphylactic shock).

The cases of lymphoma accompanied or preceded by Coombs' test positive autoimmune hemolytic anemia (AIHA) have been reported. However, Coombs' test negative AIHA prior to the diagnosis of lymphoma was rarely described. Herein, this article reports a case of non-Hodgkin's lymphoma (NHL) preceded about 1.5 years by Coombs test negative AIHA. A woman aged 69 was diagnosed with HA based on the history and laboratory tests. Further studies revealed that this patient was negative with Coombs' test for IgG, IgM, IgA and C3. After all possible causes of HA, especially malignancies were ruled out, the patient was diagnosed with Coombs' test negative AIHA and treated with prednisolone. The patient responded well initially to steroid treatment. Two recurrences of acute HA were presented at time of 10 months post steroid cessation, and immediately after an attempt to withdraw steroid, respectively, but the hemolysis was effectively controlled by reinstitution of prednisolone. At third recurrence, however, the patient was no longer responding to steroid, and was found with cervical lymphadenopathy. Coombs' test for IgG, IgM, IgA and C3 remained negative. B cell NHL was diagnosed by pathology. After receiving 6 cycles of CHOP chemotherapy, the patient was lymphoma free, but the hemolysis was not improved, however, which was effectively controlled by the following low dose-rituximab (RTX) therapy. The patient was still kept in a remission of lymphoma free of anemia. In conclusion, this report presented a very rare case of NHL with Coombs' test negative AIHA as initial major clinical manifestation.

On account of the dense cuticles of the fresh stem and the light, hard and pliable texture of the dried stem, Dendrobii Caulis is difficult to dry or pulverize. So, it is very important to the ancient doctors that Dendrobii Caulis should be properly treated and applied to keep or evoke its medicinal effects. The current textual research results about the preliminary processing, processing and usage methods of Dendrobii Caulis showed that: (1) In history the clinical use of fresh or processed Dendrobii Caulis as teas and tinctures were very common. (2) Its roots and rhizomes would be removed before using. (3) Some ancillary approaches were applied to shorten drying times, such as rinsing with boiling mulberry-ash soup, washing or soaking with liquor, mixing with rice pulp and then basking, etc. (4) According to the ancients knowledge, the sufficient pulverization, by means of slicing, rasping, hitting or pestling techniques, was necessary for Dendrobii Caulis to take its effects. (5) The heat processing methods for Dendrobii Caulis included stir-baking, stir-frying, steaming, decocting and stewing techniques, usually with liquor as an auxiliary material. Among above mentioned, steaming by pretreating with liquor was most commonly used, and this scheme was colorfully drawn in Bu Yi Lei Gong Pao Zhi Bian Lan (Ming Dynasty, 1591 CE) ; moreover, decocting in advance or long-time simmering so as to prepare paste products were recommended in the Qing Dynasty. (6) Some different processing programs involving stir-baking with grit, air-tightly baking with ondol (Kangs), fumigating with sulfur, which appeared in modern times and brought attractive outward appearance of the drug, went against ancients original intentions of ensuring drug efficacy.

OBJECTIVETo investigate the effects of Huchang Qingfei concentrated pellets on the expression of E-cadherin (E-cd) in the lung tissue from mice infected with Mycoplasma pneumoniae (MP).

METHODA mice model of Mycoplasmal pneumonia (MPP) was developed by repeatedly intranasal infectious route. Transmission electronic microscope (TEM) and immunohistochemistry stain were performed to observe the pathological changes and expression of E-cd in lung tissues.

RESULTUnder TEM it was found that the cellular membrane was ruptured, mitochondria was denatured, crista was broken in the pulmonary cells of the model group; the all above parameters in Huchang medicated group were improved obviously. The immunohistochemistry test showed that strong positive brown stain of E-cd expression was found in the pulmonary epithelial cell membrane and bronchial periphery in the model group, however, in the medicated group, the E-cd expression level in the cellular membrane was decreased and the expression ratio was dropped significantly as compared with the model controls.

CONCLUSIONHuchang Qingfei concentrated pellets can inhibit the overexpression of E-cd in the lung tissue of mice with MP-infection, which may be helpful for prevention and treatment of pulmonary injury caused by MPP.

OBJECTIVETo investigate the effect of heme oxygenase-1 (HO-1) expression on cell growth and apoptosis in imatinib resistant chronic myeloid leukemia (CML) cells (K562/A02-IM), and explore the relationship between HO-1 gene and CML.

METHODSThe expression of HO-1 in 20 drug-resistant CML patients was detected by RT-PCR. Different concentrations of hemin were used to induce HO-1 expression of K562/A02-IM, HO-1 expression at different time was detected by RT-PCR and Western blot analysis. Cell apoptosis was detected by Annexin V/PI staining, and MTT assay was used to detect viability of K562/A02-IM cells after induction or inhibition of HO-1 gene by hemin and zinc protoporphyrin (ZPP).

RESULTSRT-PCR showed that HO-1 was expressed in the bone marrow mononuclear cells (BMMNCs). When treated with hemin at different concentrations (0, 10, 20, 40 µmol/L) for 16 h, the expression of HO-1 in K562/A02-IM was increased in a dose-dependent manner, and peaked at 20 µmol/L of hemin for 16 h. The apoptosis rates were (17.61 ± 0.01)%, (12.13 ± 0.11)%, (7.94 ± 0.03)% and (4.62 ± 0.15)% at 0,10, 20 and 40 µmol/L of hemin respectively for 16 h and were (14.7 ± 0.05)%, (8.1 ± 0.07)% and (16.3 ± 0.13)% at 20 µmol/L of hemin treatment for 8,16, and 24 h respectively. Hemin induced apoptosis of K562/A02-IM cells in a dose-dependent manner. The expression of HO-1 was induced in K562/A02-IM cells in a dose-dependent manner, and the survival of K562/A02-IM cells was significantly increased as compared to that of control group. When HO-1 was inhibited by ZPP, the cells survival was sharply decreased compared to that of the control group (P < 0.05).

CONCLUSIONHO-1 was expressed in the BMMNCs. It is a kind of molecules whose expression can be induced and can promote the growth of drug-resistant cells. Inhibition of HO-1 expression probably be used for the treatment of drug-resistant CML.

OBJECTIVETo assess the clinical effect and safety of the Chinese medicine Longbishu Capsule combined with mesylate doxazosin in the treatment of benign prostatic hyperplasia (BPH) of the kidney deficiency and blood stagnation type.

METHODSThis was a randomized, double-blind, double-simulation control study. We equally assigned 60 men diagnosed with BPH of the kidney deficiency and blood stagnation type to an experimental and a control group, the former treated with mesylate doxazosin plus Longbishu Capsule and the latter with mesylate doxazosin plus placebo. We compared the International Prostate Symptom Score (IPSS), quality of life (QOL), Chinese symptom score (CSS), maximal urinary flow rate (Qmax), and prostate volume between the two groups of patients before and after 6 months of medication.

RESULTSAfter treatment, there were 5 cured cases, 13 markedly effective cases, 9 effective cases, 1 ineffective case, and 2 eliminated cases in the experimental group, as compared with 2 cured cases, 8 markedly effective cases, 10 effective cases, 7 ineffective cases, and 3 eliminated cases in the control group. The total effectiveness rate was obviously higher in the former (96.4%) than in the latter (74.1%). IPSS, Qmax, and CSS were improved in both of the groups after medication, even more significantly in the experimental than in the control group (IPSS: 15.22 ± 2.98 vs 18.15 ± 5.88, P <0.05; Qmax: [13.56 ± 2.26] ml/s vs [11.78 ± 2.97] ml/s, P <0.05; CSS: 6.18 ± 2.13 vs 9.52 ± 3.15, P <0.05). Because of the difference in the QOL score between the two groups at the baseline (P = 0.038 <0.05), no more comparison was made in this aspect after treatment.

CONCLUSIONThe combination of Longbishu Capsule with mesylate doxazosin is safe and effective for the treatment of BPH.

Enzymatic esterification by reacting caparic acid with glycerol in solvent-free system was studied. Lipases from Pseudomonas fluoresces(PFL), Mucor miehei(MML) and Candida antarictica(CAL) possessed good catalytic activity. The optimal reaction conditions to convert capric acid with CAL are: 60 degrees C, 20-100 u of CAL per gram capric acid, 12% (W/W) of initial water content in glycerol. CAL does not express its 1,3-specificity in final product. Mechanical fraying denatured CAL partly. 96.4% of catalytic activity of CAL recovered after 5 batches of reaction. Extraction with sodium carbonate solution can decrease acid value of product from 9.8 mg KOH/g to 0.68 mg KOH/g. Applying the enzymatic esterification in open system, under vacuum or dehydrating with molecular sieves all dehydrate effectively. Molar ratio of reactants does not influence the total conversion of capric acid but influences the yield of monoglyceride. With certain protocols, the reaction period could be shortened dramatically; conversion of capric acid reached 96.9% in 5 h.

OBJECTIVETo study the expression of NFkappaB p65 and its target genes in intestinal metaplasia (IM), dysplasia (Dys), gastric cancer (GC) infected with Helicobacter pylori (Hp) and explore the mechanism of infection by cytotoxin-associated antigen A expressing Hp (CagA(+)Hp) in the development of gastric cancer.

METHODSCagA antibody in blood sample of 289 patients was determined by ELISA. Hp was detected by rapid urease test and Warthin starry staining. Expression of NFkappaB p65 and its target genes in IM, Dys and GC was examined by immunohistochemistry.

RESULTSIn IMI approximately II, IMIII, DysI, DysII approximately III and GC, the expression of NFkappaB p65 was significantly higher in patients with CagA(+)Hp infection than those without CagA Hp infection. In IMIII and DysII approximately III, the expression of NFkappaB p65, c-myc, CyclinD(1) and bcl-xl was significantly higher in patients with CagA Hp infection than those without CagA Hp infection. In gastric cancer infected with CagA(+)Hp, the expression of NFkappaB p65, c-myc, CyclinD(1) and bcl-xl was significantly higher in intestinal type than in diffuse type.

CONCLUSIONThere are different mechanisms in intestinal type and diffuse type in the development of gastric cancer. The occurrence of intestinal type gastric cancer is associated with CagA(+)Hp infection which by NFkappaB p65 upregulating the expression of c-myc, CyclinD(1),bcl-xl in patients with IMIII, DysII approximately III. It may be an effective method to prevent gastric cancer by inhibiting NFkappaB p65.
