·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 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.

OBJECTIVEThe Ala499Val (C > T) and Lys939Gln (A > C) of the XPC gene are two potentially functional nonsynonymous polymorphisms, which affect the rate of DNA repair and might change XPC production and activity. This study aimed to explore the distribution of these two polymorphisms in the Chinese Han population and their relationship with male infertility.

METHODSWe genotyped the two polymorphisms of the XPC gene by the PCR-restriction fragment length polymorphism (PCR-RFLP) method in 318 infertile patients and 228 fertile male controls, detected the frequency of the alleles, and analyzed both the individual and the joint contribution of the two polymorphisms to male infertility.

RESULTSFor the Ala499Val (C > T) polymorphism, the frequencies of the CC, CT, and TT genotypes were significantly different in distribution between the patients and the controls (P = 0.020). Males with the TT genotype had a lower risk of male infertility than those with the CC genotype (adjusted OR = 0.49, 95% CI: 0.23-0.88), and even lower than those with both CC and CT genotypes (adjusted OR = 0.39, 95% CI: 0.22-0.71). The Lys939Gln (A > C) polymorphism was not related with male infertility. The combined genotype analysis showed that the individuals with 1-4 risk alleles had a significantly higher risk of male infertility (adjusted OR = 2.75, 95% CI = 1.50-5.04) than those with 0 risk allele.

CONCLUSIONThe Ala499Val (C > T) polymorphism of the XPC gene is correlated with male infertility and may be a potential genetic risk factor for male infertility in the Chinese Han population.

OBJECTIVETo evaluate the impact of universal salt iodization using monitoring data on correctional status of iodine deficiency and hospitalized thyroid diseases.

METHODSRetrospective survey was conducted to collect medical records of hospitalized thyroid disease cases. Routine monitoring data on population iodine nutrition status and goiter prevalence were analyzed.

RESULTSThe coverage of adequately iodized salt was consistently above 95%. Hospitalization rate of thyroid diseases rose steadily, and peaked at 54.5 per 100,000. The proportion of hospitalized thyroid disease among hospitalized diseases also rose with female and those aged above 40 years old mostly affected. The proportion of hospitalized hyperthyroidism among total hospitalized thyroid disease rose from 13.6% to 34.7%.

CONCLUSIONSUniversal salt iodization might eliminate iodine deficiency while other impact still exists. However, the benefits of universal salt iodization should be far overweight the adverse effects.
