Objective To investigate the expressions of nitric oxide synthase (NOS) protein and mRNA in the lung of rats with hepatopulmonary syndrome. Methods Male Sprague-Dawley rats were divided into four groups: sham operation (SO), intrahepatic portal hypertension (IHPH), prehepatic portal hypertension (PHPH) and portasymstimic shunt (PCS). Two weeks after preparation of rat models, the following measurements were performed: arterial blood gas analysis; the concentrations of NO in lungs; in situ hybridization of ecNOS and iNOS mRNA expressions in lung tissue sections with digoxin-labeled ecNOS and iNOS oligonucleotide probes; expressions of ecNOS and iNOS proteins by immunohistochemisty; image and semiquantitative analysis of the expressions of ecNOS, iNOS and their mRNA. Results PaO_ 2 was (73.85?6.51) mmHg in IHPH rats, significantly lower than that in PHPH, PCS and SO rats97.39? 1.33, 95.23?2.22 and (99.05?0.75)mmHg, respectively.The level of lung NO of IHPH was(19.78?5.33)?mol per gram of protein,much higher than that of PHPH, PCS and SO 13.21?3.99,13.89?3.16 and (8.71?1.68)?mol per gram of protein,respectively. In capillary endothelia, positive expressions of ecNOS mRNA and ecNOS protein in IHPH(4.96?0.82,4.11?0.28) were significantly higher than those of PHPH (1.81? 0.39, 1.63?0.18), PCS (1.88?0.53,1.83?0.16)and SO(1.19?0.32,0.98?0.20). Conclusion The expressions of NOS protein and mRNA in the lung of rats with hepatopulmonary syndrome were increased, and the level of lung NO was elevated, which seems to play an important role in the pathogenesis of hepatopulmonary syndrome.

Objective To explore the biomechanical property on Suture-Button and conventional screw fixating the distal tibiofibular syndesmosis injury.Methods The distal tibiofibular syndesmosis injury models were made by cutting the anteroinferior tibiofibular ligaments,posteroinferior tibiofibular ligaments,interosseous tibiofibular ligaments or deltoid ligaments of 8 fresh frozen calves.These models were randomly and equally divided into the two groups.The two groups were respectively fixed by Suture-Button and conventional screw.The contact area and peak intra-articular pressure of tibiatalar joint were measured by biomechanical testing methods and the stress and strain sensing technology.Results The maximal contact area and peak intra-articular pressure of Suture-Button fixation group had no significant differences with the conventional screw group by the four kinds of ankle flexion-extension angles in the sagittal plane (t =3.52,4.49,5.93,4.75,all P ＞ 0.05),peak intra-articular pressure was also similarly improved (t =3.61,3.97,4.68,2.41,all P ＞ 0.05).But biomechanical markers of two fixation groups had an improvement trend.Conclusion Suture-Button fixing the distal tibiofibular syndesmosis injury had similar biomechanical effect to compare with traditional conventional screw,and two fixation groups both improved trend to compare with ligament-cut group.

Objective To investigate the effect of carboxyl methyl chitosan on hypertrophic scars by establishing a hypertrophic scar model on the ventral side of rabbit ears.Methods Full-thick-ness excisional wounds,1 cm in diameter,were made in the ears of 12 adult New Zealand white rabbits,and 123 hypertrophic sears were made in all.Then the rabbits were divided into 3 groups:group A was an experimental group (carboxyl methyl chitosan,500μg/ml),group B was a control group 1 (triamcinolone),and group C was control group 2 (physiological saline).All the scars were injected with drugs on the 30th and 40th days after operation,and then the samples were collected on the 35th and 45th day and analyzed.Results Compared with group C,group A appeared to be flatter,softer,and lighter in color;the area density of fibroblast decreased using HE stain and masson stain (P<0.05),and hydroxyproline content and hypertrophic index were also lower than group C (P<0.05).There were no significant differences of those criteria between group A and group B (P>0.05).Conclusion Injection of carboxyl methyl chitosan into Iocal hypertrophic scars On rabbit ears has similar effects to triamcinolone,and both of them can prevent and cure hypertrophic scars in proliferative stage.

Objective To detect CD_(36) expressions in polycystic ovary (PCO), and to explore its correlation with local androgen and insulin at transcription level. Methods From August 2002 to February 2003, 12 patients with asymmetric PCO, 15 primary or secondary infertile patients without endocrine disorders and 8 polycystic ovary syndrome (PCOS) with bilateral PCO were recruited. Extraction of follicular fluid and detection of testosterone(T), dehydroepiandrosterone sulfate (DHEAS), insulin (INS) and androstenedione (A_2) were performed. Relative CD_(36) mRNA expression level of human ovarian inner thecal cells was analyzed by auto image analysis system (IAS) after RT-PCR. Results The level of CD_(36) mRNA expression in thecal cells was 0.24?0.07 in polycystic ovary of PCO group and 0.21?0.05 in bilateral ovaries of PCOS group, respectively, which were significantly lower than 0.83?0.13 in normal ovaries (P

We have designed a sort of multi-functional bone forceps for use as orthopedic surgical instruments to grip, bend and cut the spicula. It is labor-saving and easily installed. Its left and right clamp bodies are connected by a rivet to hold the spicula, and the pressure-regulating shank is connected with the clamp seat body at the right top of the clamp body by a rivet. It is used to curve the spicula. At an appropriate location on the pressure-regulating shank is a pin-cutting chip. On the right body rotating disc-clamp, there is a rectangular open cutting groove to be in use for cutting the specula with the role of pin-cutting chip. Being characterized by the use of mechanical leverage, the manipulations of holding and bending are less arduous. After achieving the 90-degree bend, the operator can cut off the specula successfully. The operation is easy to perform and labor-saving; the forceps can further meet the actual clinical demand.

This study was aimed to construct a prokaryotic expressing vector of Hap gene from Nontypeable Haemophilus influenzae, and express and identify the fusion proteins of Hap-His in E. coli. The gene encoding protein Hap was amplified from Nontypeable Haemophilus influenzae ATCC49247 chromosomal DNA by PCR, then it was cloned into prokaryotic expression plasmid pET-32a (+). The recombinant plasmid pET-32a(+)-Hap was transformed into E. coli BL21 and expression was induced by Isopropy-beta-D-thiogalatoside(IPTG). The Hap-His fusion protein expressed so was analyzed by SDS-PAGE and Western-blot. The results showed that the recombinant expressive plasmid pET-32a (+)-Hap was constructed successfully, and the recombinant plasmid expressed Hap-His fusion protein with relative molecule mass 176 000 and mainly existed in inclusion body. This fusion protein could combine with anti-His monoclonal antibody specifically through Western blot analysis. Successful expression of Hap-His fusion protein in prokaryotic cell could lay a basis for further study of immunocompetence of Hap protein and development of NTHi vaccine.

OBJECTIVETo study the activity of esterases, including butyrylcholinesterase (BchE), carboxylesterase (CarbE), paraoxonase (PonE) and acetylcholinesterase (AChE), and to explore the effect of genetic polymorphism on the activity of esterase for workers exposed to organophosphorus pesticides (OPs).

METHODSTwo hundred and forty-one long term OPs directly exposed workers and 151 indirectly exposed workers in the same factory were taken as study group. One hundred and sixty unexposed persons were taken as control group. The activity of serum enzymes was measured and the polymorphic distribution was detected using 7900 genotype detecting system and CMOS Chip technique. The effect of long-term exposure to organophosphorus pesticides was analyzed.

RESULTSThe activities of BchE, CarbE and PonE were independent on the gender or age in control group. Average values of Carb and BchE activities of directly and indirectly exposed workers were lower than those in control group respectively. PonE activity in directly exposed group was lower than that in control group. AChE activity in directly exposed group was lower than that in indirectly exposed group. All the differences were significant (P < 0.01). In the direct exposure group, the frequency of three variants of butyrylcholinesterase gene K (BCHE-K) polymorphism was 74.3%, 24.1% and 1.6% for UU, UK and KK respectively. Frequency of allele U and K was 0.863 and 0.137 respectively in the same group. Frequency of three variants of PON192 polymorphism was 15.0%, 45.5% and 39.5% for AA, AB and BB respectively in direct exposure group. Gene frequency of low activity (PON*A) and high activity (PON*B) was 0.378 and 0.622 respectively. Frequency of three variants of PON55 polymorphism was 96.2%, 3.8% and 0% for MM, LM and LL respectively in direct exposure group. Frequency of allele M and L was 0.981 and 0.019 respectively in the same group. The activity of PON was different in various genotypes of PON192 and PON55.

CONCLUSIONThe long-term exposure to OPs could inhibit the activities of CarbE, BchE, PonE and ACh E in different level. The genetic polymorphisms of PON192 and PON55 affect the activity of PonE, which is related to the detoxification of OPs and health impact.

Human diphyllobothriasis is a parasitic disease caused by ingestion of larvae (plerocercoids) in raw or undercooked fish and commonly found in temperate areas. Rare cases were reported in tropical or subtropical areas especially in children. The first documented case of pediatric diphyllobothriasis in Taiwan had been reported 11 years ago. Here, we report another 8-year-old girl case who presented with a live noodle-like worm hanging down from her anus, with no other detectable symptoms. We pulled the worm out and found the strobila being 260 cm in length. Examination of gravid proglottids showed that they were wider than their lengths, containing an ovoid cirrus sac in the anterior side and the rosette-shaped uterus. Eggs extracted from the uterus were ovoid and operculated. Diphyllobothrium latum was confirmed by molecular analysis of the mitochondrial DNA cytochrome c oxidase subunit 1 (cox1) gene. The girl was treated with a single oral dose of praziquantel, and no eggs or proglottids were observed from her stool in the subsequent 3 months. The reemergence of human diphyllobothriasis in non-endemic countries is probably due to prevalent habit of eating imported raw fish from endemic areas. This pediatric case raised our concern that human diphyllobothriasis is likely underestimated because of unremarkable symptoms.
