Objective To explore the early diagnosis and treatment of congenital mesenteric hiatual hernia.Methods A retrospective study was carried out in 4 patients with congenital mesenteric hiatual hernia in Tongji hospital from Nov.2005 to Mar.2007,and combining lite-rature,the diagnosis and treatment of mesenteric hiatal hernia was summed up.Results Four patients were diagnosed in operation.One case was thought as adhesive intestinal obstruction before operation;two patients were on emergency operation and 2 patients were on time-elective operation;one patient preoperative CT scan may suggest mesenteric hiatal hernia;one case had partial resection of small intestinal,the others were replaced the intestine and fixed the defect.One patient occurred early septic shock;all of them had get well.Conclusions It′s hard to diagnose the congenital mesenteric hiatual hernia before operation.Abdomen CT examination and multislice spiral CT angiography (MSCTA) help to diagnose.Early diagnosis and timely operation are the therapeutic key of congenital mesenteric hiatual heria.For the patients with recurrent abdominal pain,who was not confirmed with a variety of inspection,laparoscopic exploration can provide diagnosis,and can take the initiative to control the development of disease.

0.05).Conclusions Serum DAO can be used as a sensitive marker to early diagnose gastrointestinal dysfunction in critical neonates.Serum D-lactate will be of high specific clinical significance in diagnosis,the change of D-lactate may have relations to the features of intestinal microflora in early neonates.

OBJECTIVETo observe the therapeutic efficacy of Dangfei Liganning Tablet (DLT) in the treatment of antipsychotics induced mild hepatic damage.

METHODSTotally 80 mental inpatients with antipsychotics induced mild liver injury were randomly assigned to two groups, the treatment group (40 cases) and the control group (40 cases). Patients in the treatment group took DLT, two tablets each time, three times per day, while those in the control group took Liver-protecting Tablet (LT), four tablets each time, three times per day. The treatment course was 4 weeks for all. Changes of glutamic-pyruvic transaminase (ALT) and glutamic-oxalacetic transaminase (AST) were observed before treatment, week 1, 2, and 4 after treatment. The therapeutic efficacy was compared between the two groups.

RESULTSCompared with the former time point, ALT and AST gradually decreased in the two groups at week 1, 2, and 4 (P <0. 05). The cured rate was 72. 5% and the total effective rate was 97. 5% in the treatment group. They were 62. 5% and 90. 0% respectively in the control group. There was no statistical difference in the two indices between the two group (P >0.05). No obvious adverse reaction occurred in the two groups.

CONCLUSIONDLT could treat antipsychotics induced mild hepatic damage in a safe and effective way.

Objective To evaluate the effects of different doses of propofol or isoflurane on the cochlear blood flow (CBF) in guinea pigs.Methods Fifty-four adult male guinea pigs,aged 3 months,weighing 400-500 g,were randomly divided into 6 groups (n =9 each).In P1,P2 and P3 groups,propofol was infused for 115 min at 10,20 and 40 mg· kg-1 · h-1,respectively,after a loading dose of 5 mg/kg was injected over 5 min.In S1,S2 and S3 groups,isoflurane was inhaled for 120 min with end-tidal concentrations of 1％,2％ and 3 ％,respectively.Mean arterial pressure and CBF were recorded before administration (baseline,T1) and during the period of drug administration.Distortion product otoacoustic emission (DPOAE) was measured at T1,at the end of administration (T2) and 1 h after administration (T3).Five animals in each group were sacrificed and organs of Corti were harvested for observation of morphology of out hair cells by scanning electron microscopy.Results Propofol decreased MAP and increased CBF and DPOAE amplitude in a dose-dependent manner.Isoflurane decreased MAP and CBF in a dose-dependent manner.1％ isoflurane increased DPOAE amplitude,however,2％ and 3％ isoflurane decreased it and caused damage to out hair cells.Conclusion Propofol induces an increase in CBF in guinea pigs,while high concentration of isoflurane induces a decrease in CBF.Isoflurane inhibits CBF autoregulation,which makes CBF more sensitive to perfusion pressure,thus causing damage to hearing function.This is the reason why high concentration of isoflurane induces a decrease in CBF.

OBJECTIVEIn order to elucidate role of RUNX3 gene in hepatocarcinogenesis, we detected genetic and epigenetic alteration of RUNX3 gene in hepatocellular carcinoma (HCC).

METHODSPCR-SSCP, analysis of loss of heterozygosity (LOH), sequencing and methylation-specific PCR (MSP) were used to detect mutation, LOH and DNA methylation of RUNX3 gene in 90 HCCs.

RESULTSNo mutation was found, but three single-nucleotide polymorphisms (SNP) were found and distributed over exon1 and exon4. 30.6% (11/36) of cases showed LOH; 54.4% (49/90) of cases was in hypermethylation. There is a significant correlation between LOH and major portal vein invasive or micro vessel invasion or intrahepatic metastasis.

CONCLUSIONHigh frequent hypermethylation and LOH of RUNX3 gene were found in HCC. Aberrant RUNX3 gene may play an important role in the development of HCC.

The focus of microbiologists has moved to the rare actinomycetes.For selective isolation of rare actinomycetes that all play the important role in bioactive compounds,the approaches which involve the methods using gellan gum and flooding solution、 rehydration-centrifugation(RC)、 extremely high frequency radiation(EHF)、 bacteriophage and sucrose-gradient centrifugation were introduced in this paper.

Objective To develop an effective way to evaluate the accurate platelet count in a patient with anticoagulants-induced pseudothrombocytopenia (PTCP).Methods It was studied that various anticoagulants effect on the platelets count for an infrequent patient with anticoagulants-dependent PTCP. When vitamin B6,aminophylline,gentamicin and amikacin were separately added to four anticoagulated blood samples from anticoagulants-dependent patient within 15 min after blood withdrawal,platelets count and morphological changes of blood cells after 4 hours of incubation at room temperature were investigated. The best anti-aggregating agent and its optimal concentration among them were explored.Results The four anticoagulants all could not inhibit the aggregation of the patient's platelets.Only amikaein among the above anti-aggregating agents can prevent and dissociate the aggregation of platelets without apparent morphological changes of blood cells and the platelet counts was stable within 4 hours after blood drawn when amikacin was added either before or after blood sampling.With increasing the concentration of amikaein,the platelet counts increase and then tend to be stable.The optimal concentration of amikacin is 5 mg/ml blood.Conclusions The supplementation of amikaein either before or after blood sampling is a useful method for the diagnosis anticoagulants-dependent PTCP and for the eva/uation of platelet counts in infrequent patients with anticoagulants-dependent PTCP.
