To summarize Professor LIU Feng-bin's clinical experience and theoretical thoughts on chronic atrophic gastritis (CAG), the study group designed a retrospective study on his case series and expert interview. First of all, the data of CAG patients treated in the First Affiliated Hospital of Guangzhou University of Chinese Medicine between 2009 and 2013, e. g. herbs, diseases, syndrome type, prescription amount and number of herbs, was collected and processed. The statistical description and binary logistic regression were used to determined the syndrome type, initial basic remedy and modification. During the statistics, a complete and sub-group analysis was performed simultaneously. After the expert interview, the syndrome type and medication were finalized. As a result, a total of 228 CAG patients aged at (50.30 ± 10.18) were collected, including 151 males (66.23%). Of them, the TCM diagnosis and syndrome type were extracted from the information of 157 patients, including 115 cases with gastric stuffiness, 23 cases with gastric pain, 19 missing cases, 2 cases with spleen-stomach weakness syndrome, 57 cases with spleen deficiency and dampness-heat syndrome, 18 cases with spleen-stomach disharmony syndrome, 23 cases with syndrome of liver depression syndrome, 21 cases with liver qi invading stomach syndrome and 26 qi and yin deficiency syndrome, respectively. All of the 228 patients used totally 104 herbs, while the subgroups with 157 patients used 94 herbs. The most frequently used 15 herbs used in each groups were analyzed to determine the initial basic remedy and modification. Subsequently, based on the information of the sub-groups with 157 patients, with the syndrome type as the dependent variable, the logistic regression analysis was made on the most frequently used 32 herbs, in order to determined the modification in herbs for different syndrome types. After experts reviewed and modified, they believed the main causes of CAG were dietary irregularities, moodiness and weak constitution; the pathogenesis of CAG was spleen deficiency with qi stagnation, heat depression and blood stasis in the stomach meridian. The above six syndrome types and 12 herbs were determined, including Pseudostellariae Radix, Poria, Atractylodismacrocephalae Rhizoma, Glycyrrhizae Radix et Rhizoma, Fritillariae Thunbergii Bulbus, Sepiae Endoconcha, Arecae Pericarpium, Aurantii Fructus, Perillae Caulis, Herba Hedyotis Diffusae, Scutellariae Barbatae Herba, Curcumae Rhizoma. This study summarized Professor LIU Feng-bin's clinical experience and theoretical thoughts of chronic atrophic gastritis based on clinical practice data and expert interview, with a rigorous design and good scientificity and practicability.

This study is to determine the content of three alkaloids and establish the HPLC fingerprint of "Jianlian" Nelumbinis Plumula. The HPLC method of content determination was as follows: Thermo C18 (4. 6 mm x 250 mm, 5 μm) was conducted with acetonitrile-sodium dodecyl sulfonate solution-acetic acid (56: 43: 1) at a flow rate of 1.0 mL x min(-1). The monitoring wavelength was set at 282 nm and the column temperature was 35 degrees C. The method of HPLC fingerprint was as follows: Agilent ZORBAX SB-Aq C18 (4.6 mm x 250 mm, 5 μm) was conducted with gradient elution of methanol and water at a flow rate of 0.8 mL x min(-1), the monitoring wavelength was set at 282 nm and the column temperature was 35 degrees C. Similarities evaluation and hierarchical clustering analysis were applied to demonstrate the variability of 12 batches of "Jianlian" Nelumbinis Plumula samples. The results demonstrated that 11 batches showed good similarity on chemical constituents. The method could well display the chemical information of "Jianlian" Nelumbinis Plumula. It was simple, reliable and could be used for the chemical quality control of "Jianlian" Nelumbinis Plumula.

AIMTo prepare liposomes of nosiheptide and study its ability to inhibit hepatitis B virus HBsAg and HBeAg secreted.

METHODSLiposomes of nosiheptide was prepared by sodium deoxycholate dialysis and sonication. Nosheptide was determined by HPLC and partical size was determined by using laser light scattering instrument. Transmission electron microscopy (TEM) was used to examine the morphology of liposomes. Its actions to inhibit hepatitis B virus HBsAg and HBeAg secreted was studied by a HBV-transfectted cell line (HepG2 2. 2. 15 ).

RESULTSEncapsulation efficiency of liposomes by chloroform:methanol (2:1, v/v) was higher than that by dioxane. With the increase of the ratio of nosiheptide: PC (W/W), the encapsulation efficiency of liposomes decreased with the increase of ratio of sodium deoxycholate: PC, the liposomes partical size decreased. The liposomes kept stable at -20 degrees C after 2 years. The drug concentrations of liposomes that inhibit HBsAg secreted by (46.9 +/- 2. 6) %, (55.4 +/- 1.2) %, (65 +/- 3) % and HBeAg secreted by (15.1 +/- 2.3) %, (36.2 +/- 1.7) %, (36.8 +/- 2.5) % were 1.25, 2.5, 5.0 microg x mL(-1), respectively.

CONCLUSIONLiposomes of nosheptide can be prepared by sodium deoxycholate dialysis and sonication, which ability to inhibit hepatitis B virus HBsAg and HBeAg secreted is better than nosheptide.

OBJECTIVETo study the validity of transplanting transverse colon to replace esophagus in treating cicatricial stricture resulting from severe esophageal chemical burns in children.

METHODSA retrospective study was carried out on the clinical data of 46 patients with severe chemical esophageal burns who were treated from November 1972 to September 2008. The transverse colon with the ascending branch of the left colic artery was brought through a retrosternal tunnel to replace strictured esophagus. Thirty-two patients underwent colon-esophageal anastomosis and 14 patients underwent colon-pharyngeal anastomosis.

RESULTSAll patients survived after surgery, but complications occurred in 7 cases, including leakage of anastomosis in cervical region in 4 cases, stenosis of anastomosis in 2 cases, and dyspnea in 1 case, and they were cured after due treatment. Follow-up study (1 - 26 years) in 39 patients revealed that there was no difference in growth, development and diet between the patients and the normal children of the same age.

CONCLUSIONSEsophageal reconstruction with transverse colon together with the ascending branch of the left colic artery through a retrosternal tunnel is a valuable method for treating cicatricial stricture of the esophagus secondary to severe chemical burns of the esophagus in children.

Total body irradiation combined with cyclophosphamide (TBI/CY) and busulphan combined with cyclophosphamide (BU/CY) are standard conditioning regimens in hematological stem cell transplantation for patients with myelogenous leukemia. This study was aimed to compare the therapeutic efficacy of TBI/CY and BU/CY as conditioning regiment for acute or chronic myelogenous leukemia. The Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, CNKI, CBM (Chinese Bio-medicine Database) had been searched for all relevant articles (1999-2007). Comparative studies were carried out on clinical therapeutic effects of TBI/CY and BU/CY including stem cell engraftment, relapse, complications, transplant-related mortality, and disease-free survival. A meta-analysis was performed using Review Manager 4.2 software and funnel plot regression was adopted to assess the publication bias. The results indicated that 2149 articles in English and 46 articles in Chinese were got, and finally 9 clinical trials with total 3039 patients have been assessed. No significantly difference was found in engraftment failure and transplant-related mortality resulting from TBI/CY and BU/CY conditioning regimens, but the incidence of veno-occlusion of liver and hemorrhagic cystitis obviously increased in BU/CY group after transplantation, the acute GVHD, interstitial pneumonia and cataract significantly increased in TBI/CY group. The relapse rate of AML in TBI/CY group was lower than that in BU/CY group, and the rate of long-term disease-free survival of AML patients in TBI/CY group also significantly lower than that in BU/CY group, but the relapse rate of CML in TBI/CY group after transplantation was obviously higher than that in BU/CY group, but there was no difference in longterm disease-free survival rate between the two conditioning regimens mentioned above. It is concluded that the meta-analysis confirms different effects of TBI/CY and BU/CY regimens on myelogenous leukemia transplantation. This result is useful for physicians to select treatment regimens.
