Purpose:To evaluate the efficacy and toxicity of vindercine(VDS)in the interven- tional treatment of hepatic and pulmonary carcinomas.Materials and Methods:30 cases of mid-ad- vanced hepatic and pulmonary carcinomas,among them,13 eases of primary hepatic carcinomas,7 cases of matastic hepatic carinomas and 10 cases of primary pulmonary carcinomas,were treated by selective arterial infusion chemotherapy.The combination chemotherapeutic regimens conpored of VDS together with 5-Fu,MMC,carboplatin or Vp16.Results:The response rate for all cases was 60%,for primary hepatic carcinomas 61.5%,for metastic hepatic carcinoma 42.9% and for primary pulmonary carcinoma 70%.Myelosuppession was the main toxicity and 70% patients had the gastrointertional reac- tions as nusea,vomiting etc.Conclusion:VSD is a more effective drug for pulmonary carcinoma,but for hepatic carcinoma,the efficacy of VDS was unmarkable from other drugs.

Transverse fracture is the most common in patella fracture and tension band fixation is one of the most effective methods. Surgical wire tension band technique is simple, the use of materials is also simple, but it is not strong and difficult to promote. Kirschner tension band technique can get satisfactory reduction with reliable fixation, but it is easy to complicate with steel wire breakage and Kirschner loosening. Screw tension band technique inherits the traditional advantages of simple manipulation and reliable fixation, also overcomes the disadvantages of early activity limitations caused soft tissue irritation of tension band around knee, the slippage and breakage of internal fixation, and the technique can be popularized generally.

Objective To investigate the clinical and pathologic features of pulmonary sclerosing he- mangioma (PSH).Methods With clinicopathologic date of 21 cases of PSH patients obtained,all speci- mens were stained by immunohistochemical method with a panel of antibodies including CK,synaptophysin, chromogranin,actin,calretinin,F-Ⅷ,CD_(34) and vimentin.Results PSH usually affects female patients.Age ranged from 26 to 70 years old.The tumor cells showed a mixture histological pattern,with the feature of pap- illary and the proliferation of interstitutial monocyte.Immunohistochemical staining revealed that surface of the papillary cells expressed CK,monocyte expressed synaptophysin.PSH should be distinguished from bronchi- oloalveolar carcinoma,carcinoid and inflammatory pseudotumor.Conclusion PSH is a rare and potential malignant behavior tumor,and is different from benign tumor.

Line scanning quantitative analysis method on silicate with small laser beam ( < 15 μm) was developed using laser ablation sector field inductively coupled plasma mass spectrometry (LA-SF-ICP-MS). Differences on signal intensity and elemental fractionation induced by different laser sampling patterns were compared. While spot ablation with small laser beam, the elemental signal intensity decreased with time significantly, and the elemental fractionation was obvious. In contrast, the elemental signal intensity by line scanning was higher and more stable and line scanning was free of elemental fractionation. Therefore, identical ablation pattern and condition should be used for the standard and the unknown sample in LA-ICP-MS quantitative analysis. A single pulse experiment was carried out to investigate the washout time when coupled to two-volume ablation cell. The result indicated that the elemental intensity decayed to the background value needed 2-3 s. The optimal parameters on SF-ICP-MS were set to reduce the effect of signal overlapping. Homogeneous sample KL2-G and titanite grains with composition zoning were analyzed by this method. Accurate element contents and element ratios indicated that fast washout time and optimal instrument parameters made it feasible to perform line scanning quantitative analysis accurately. Comparing to traditional microanalysis, line scanning quantitative analysis could reduce the laser beam size (<15 μm) and improve the spatial resolution efficiently. The potential of the technique to unveil compositional complexities in greater detail would help to improve our understanding of geochemical processes in mineral scale.

OBJECTIVETo observe clinical therapeutic effects of acupuncture for pattern of liver-stagnation and spleen-deficiency in diarrhea-predominant irritable bowel syndrome (D-IBS) and its impact on cell factors.

METHODSForty cases were selected and divided into an acupuncture group (21 cases) in which acupuncture was applied and a medicine group (19 cases) in which oral administration of dicetel and bifidobacterium lactobacillus triple viable capsules were applied. The symptom scores, level of Th1-type cytokine (IFN-gamma, IL-2) and Th2-type cytokine (IL-4, IL-10) and ratio of IFN-gamma to IL-4 were compared in two groups before and after treatment to analyze acupuncture effect.

RESULTSThe clinical symptoms were improved after one-week treatment in the acupuncture group (P<0.05), which had faster onset than the medicine group (P<0.05). The total effective rate was 90.48% (19/21) in the acupuncture group, which was superior to 78.95% (15/19) in the medicine group (P<0.05). Compared with medicine treatment, imbalanced condition of Th1/Th2 was turning towards the direction of Th2 after acupuncture, indicating a tendency to recover the balance.

CONCLUSIONThe clinical efficacy of acupuncture for D-IBS has close relationship with effectively improving balance of Th1/Th2 in patients with liver-stagnation and spleen-deficiency.

Objective To explore the effect of chlorpromazine on neocortical high-voltage spindles(HVSs)and facial twitching in freely moving normal adult rats.Methods Continuous video,neocortical electroencephalogram(EEG)and facial electromyography(EMG)were recorded simultaneously for at least 6 h in freely moving rats.The number and mean duration of HVSs,and the facial muscular activity were analyzed after administration of chlorpromazine.Results HVSs spontaneously appeared in behavioral waking-immobility rats with accidental hyperspasmia.After rats being administrated with chlorpromazine at a dose of 1.5(mg/kg)and 3.0(mg/kg),the facial rhythmic muscular activity increased,the duration of rhythmic muscular activity prolonged,the number of HVSs increased and the mean duration of HVSs prolonged.Conclusion Chlorpromazine could enhance the physiological HVSs and facial twitching,indicating that the side effect at the extrapyramidal system of antipsychotic maybe relate to HVSs and dopamine receptor may contribute to the regulation of HVSs.

Objective To evaluate the protective rate and the variation of HFRS-IgG on hemorrhagical fever with renal syndrome (HFRS) vaccine.Methods Cluster,random sampling and cross-sectional study were used to assess the protective rate of HFRS vaccination.Level of HFRS-IgG was detected with ELISA in epidemic and non-epidemic areas of HFRS.Results Curve equation was obtained as Yprocective rate=(0.863+0.283/Xvaccination term) × 100％ by protective rate with vaccination term.Protective rates showed a reducing trend,90％ after 7-8 years of vaccination,88％ after 10 years,and 94％ on average.Absorbance (A) value of HFRS-IgG was 4 times higher in persons with vaccination than those without,in the epidemic area.Higher antibody level could be obtained after primary vaccination,but the level of antibody had a 50％ reduction after 5-10 years of vaccination,and a 60％ reduction after 10 years of vaccination.Conclusion HFRS antibody had a 50％ reduction after 5-10 years of vaccination.The protective rate of HFRS vaccination had a 90％ loss,after 7-8 years of vaccination.Booster dose was necessary after 7 years of vaccination.

OBJECTIVETo review clinical features of four male patients with glutaric academia type I and screen glutaryl-CoA dehydrogenase (GCDH) gene mutations.

METHODSThe 4 patients underwent brain computer tomography (CT) and magnetic resonance imaging (MRI) analyses. Blood acylcarnitine and urine organic acid were analyzed with tandem mass spectrometry and gas chromatographic mass spectrometry. Genomic DNA was extracted from peripheral blood samples. The 11 exons and flanking sequences of GCDH gene were amplified with PCR and subjected to direct DNA sequencing.

RESULTSAll patients have manifested macrocephaly, with head circumference measured 50 cm (14 months), 47 cm (9 months), 46 cm (5 months) and 51 cm (14 months), respectively. Imaging analyses also revealed dilation of Sylvian fissure and lateral ventricles, frontotemporal atrophy, subarachnoid space enlargement and cerebellar vermis abnormalities. All patients had elevated glutarylcarnitine (5.8 umol/L, 7.5 umol/L, 8.3 umol/L and 7.9 umol/L, respectively) and high urinary excretion of glutaric acid. Seven mutations were identified among the patients, among which c.146_149del4, IVS6-4_Ex7+4del8, c.508A>G (p.K170E), c.797T>C (p.M266T) and c.420del10 were first discovered.

CONCLUSIONMacrocephaly and neurological impairment are the most prominent features of glutaric academia type I. Blood tandem mass spectrometry and urine gas chromatographic mass spectrometry analysis can facilitate the diagnosis. The results can be confirmed by analysis of GCDH gene mutations.

OBJECTIVENeonatal intrahepatic cholestasis caused by citrin deficiency (NICCD) which resulted from mutation in SLC25A13 gene can present transient intrahepatic cholestasis, low birth weight, growth retardation, hypoproteinemia and so on. This study aimed to identify the mutation type of NICCD patients by DNA sequencing.

METHODSTwenty children diagnosed as NICCD were consented to enroll in this study. PCR assays were performed to amplify the eighteen exons and its flanking sequences of SLC25A13 gene, which were defined as the upstream and downstream 50 bp from starting and ending site of the exons. Then the PCR products were purified and followed by automated DNA sequencing. The IVS16ins3kb mutation was detected by nested PCR and RT-PCR.

RESULTSSeven genetic variations of SLC25A13, termed as 851del4, 1638ins23, IVS16ins3kb, IVS6+5G>A, c.775C>T (p.Q259X), c.1505C>T (p.P502L) and c.1311C>T (p.C437C), were identified in the subjects, of which c.775C>T (p.Q259X), c.1505C>T (p.P502L) and c.1311C>T (p.C437C) were reported for the first time in NICCD patients. And a compound mutation of［1638ins23+IVS16ins3kb］was also identified. In 20 patients with NICCD, 6 patients were 851del4 homozygotes, 7 patients were compound heterozygotes, and 7 patients were heterozygotes of single mutation. 851del4 was the major mutation type (64%), followed by 1638ins23 (15%), IVS16ins3kb (12%) and IVS6+5G>A (6%).

CONCLUSIONS851del4 is the major mutation type in Chinese patients with NICCD.
