·Hemophilia is a rare disorder that occasionally has visual symptoms after diagnosis. The authors present a case in which visual symptoms led to the initial diagnosis, a 22-year-old man who represented with spontaneous fundal haemorrhage. There is no history of bleeding and trauma. The fundal haemorrhage was absorbed significantly without any treatment after 3 months follow-up. Hemophilia A was found to be the causative disorder in this previously healthy man. The authors present a rare case in which unilateral visual complaints led to the diagnosis of hemophilia A. Thus, though uncommon, hemophilia should be considered in the differential diagnosis of otherwise unexplained fundal haemorrhages.

Ten glycosidic compounds were isolated from an ethanol extract of Machilus wangchiana by a combination of various chromatographic techniques including column chromatography over silica gel and Sephadex LH-20 and reversed-phase flash chromatography and HPLC. Their structures were identified by spectroscopic data analysis (IR, MS, and NMR) as icariside B1 (1), boscialin-3-O-β-D-glucopyranoside (2), pisumionoside (3), isolariciresinol-9'-O-β-D-xylopyranoside (4), 5'-methoxyisolariciresinol-9'-O-β-D-xylopyranoside (5), lyoniresinol-9'-O-β-D-xylopyranoside (6), (E) -4-hydroxyphenylprop-7-ene 4-O-β-D-glucopyranoside (7), (E) - 4-hydroxy-3-methoxyphenylprop-7-ene 4-O-α-L-rhamnopyranosyl-(1 --> 6) -β-D-glucopyranoside (8), 4-hydroxy-3-methoxyphenylprop-8-ene 4-O-β-D-xylopyraosyl-(1 --> 6) -β-D-glucopyranoside (9), and 4-hydroxy-3,5-dimethoxyphenylprop-8-ene 4-O-α-L-rhamnpyranosyl-(1 --> 6)-β-D- glucopyranoside (10), respectively.

OBJECTIVETo deal with the correlation between phylogeny, chemical constituents and pharmaceutical aspects of Ranunculaceae, namely a pharmaphylogenic study of this taxon.

METHODBased on chemical, pharmaceutical (both ethnopharmacologic and pharmacological) information, linking with different plant systems of Ranunculaceae.

RESULTChemical constituents of this taxon included several natural groups: benzylisoquinoline alkaloid, ranunculin, triterpenoid glycoside and diterpene alkaloid etc. Ranunculin and magoflorine were found to present simultaneously in some plants of this taxon.

CONCLUSIONCombining with therapeutic information, pharmaphylogenic research were in accordance with the phylogenetic system presented by Tamura that Ranunculaceae was proposed to be divided into six sub-families: Helleboroideae, Ranunculoideae, Cimicfugoideae, Isopyroideae, Thalictroideae and Coptidoideae. Results also supported the establishment of Cimicifugoideae.

OBJECTIVETo provide scientific basis for the utilization and development of Valeriana jatamansi by setting up the quality control specification of V. jatamansi.

METHODThe pharmacognostical methods were applied. The extract of V. jatamansi was examined. Moisture and ash were determined. And the bioactive constituents were analyzed by TLC and HPLC.

RESULTThe morphological and histological characters of V. jatamansi were observed. Content of total ash, acid-insoluble ash, and moisture of 15 samples from different habitats and times were determined. The qualitative and quantitative analysis of valtrate and acevaltrate by TLC and HPLC were preformed respectively.

CONCLUSIONThe established method can be used for the quality control of V. jatamans.

OBJECTIVETo compare the results of application of Qu single abdominal aorta clamping for bloodless hepatectomy and Pringle hepatectomy in 118 cases of liver tumors.

METHODSThe clinical data of 118 patients, including 59 patients undergoing Qu single abdominal aorta clamping for bloodless hepatectomy (Group QG) and 59 patients undergone Pringle first hepatic portal clamping hepatectomy (Group PG) since March 2009 in the Ningbo Tumor Hospital and Jiangxi Provincial Hospital were retrospectively reviewed. The changes of blood pressure, oxygen saturation, urine volume, intravenous fluid volume, amount of bleeding, time of abdominal aorta (or first hepatic portal) clamping, duration of operation and anesthesia, and other intraoperative indexes of the two groups were compared, and the changes of peritoneal drainage, blood tests, liver functions, etc. before operation and 1, 3, 7, 14 days after the hepatectomy in the two groups were also analyzed.

RESULTSAfter taking appropriate measures for intraoperative blood pressure control, only small fluctuations of blood pressure, which could be safely adjusted and controlled with stable vital signs, was observed in the group QG. The amount of intraoperative bleeding in the group QG was (96.25 ± 18.45) ml, significantly less than (536.25 ± 35.65) ml in the group PG (P < 0.05). In the group QG, both the duration of operation time [(227.58 ± 28.20) min] and duration of anesthesia [(249.48 ± 31.35) min] were significantly shorter than that [(261.46 ± 32.12) min and (286.58 ± 35.62) min, respectively] in the group PG (both P < 0.05). The postoperative liver dysfunction in the group QG was also milder than that in the group PG (P < 0.05).

CONCLUSIONSFor liver tumor patients, Qu single abdominal aorta clamping for bloodless hepatectomy can basically achieve the goal of bloodless hepatectomy. This surgical operation is simple and safe, worthy of recommendation to skillful liver surgeons in hospitals there are some difficulties of blood supply.

OBJECTIVETo evaluate the efficacy and safety of Capsule metadoxine in the treatment of alcoholic liver disease.

METHODSA randomized double blind multicenter placebo-controlled clinical study was performed to evaluate the therapeutic effectiveness and safety of capsule metadoxine. Patients in metadoxine group received capsule metadoxine 500mg tid po. Patients in placebo group received placebo 2 pillows tid po. The treatment duration was 6 weeks. Patients were followed up 2 weeks after the treatment. Patients were visited once every 3 weeks during the treatment period. Clinical symptoms and liver function were evaluated in all the patients before treatment, at week 3, week 6 and 2 weeks after therapy. CT scan was done in some patients before treatment and at the end point of therapy.

RESULTS254 patients were recruited in the study, 126 in metadoxine group and 128 in placebo group. Median ALT, AST, GGT level in metadoxine group were decreased from 80.0 U/L, 59.2 U/L, 123.0 U/L (before treatment) to 41.1 U/L, 36.0 U/L, 57.0 U/L (after 6 weeks therapy). The improvement in liver function was more significant in metadoxine group than in placebo group (P less than 0.05). For the patients who stopped drinking during the study, the total effective rate of improvement in liver function was 82.8% in metadoxine group, much higher than that in placebo group (55.7% , P=0.0000). For the patients who did not stop drinking during the study, the total effective rate of improvement in liver function was 65.4% in metadoxine group, which is not significantly higher than that in placebo group (44.8%, P=0.1767). The CT value ratio of liver to spleen was significantly improved in metadoxine group (P=0.0023), and there was no significant difference between the two groups (P=0.6293). The rate of adverse was 1.6% in both of groups.

CONCLUSIONCapsule metadoxine is an effective and safe treatment for alcoholic liver disease.
