A study on the clinical, paraclinical and epidemiological features of 68 patients with hypertrophy simple goiter with complication in Hue hospital during 1996-1998 has shown that the disease occurred mainly in the women with ages of 31-50. The goiter accompanying with the nuclear accounted for high rate, especially multinuclear. The operation indicated for cases of goiter with pressing the neck region or with nuclear. The results of postoperative monitoring within 4 months found good (86,8%), normal (8,8%) and poor (4,4%).

Among them, 76.6% had this morbid history of 1-6 years, 81.3% had the cause of allergy and 42.2% of infection. Good and fairly good results made up 93.7%, poor results 6.3%

The study was carried out on 320 patients with sinusititis at Hue Centre Hospital from Sept. 1998 to Mar. 2000; 76.5% of patients were 16-45 years old, 43.8% male and 56.2% female, 43% with 1 year long of the disease. The causes were infection 76.5%, allergy rhins-sinusitis 50.9%. Favorable factors: 49.1% local, 11.6% environmental, 2.5% systemic status. Clinical symptoms were headache 71.5%, cararrhal rhinitis 65.3% (posterior) and 48.4% (anterior), obstructive rhinitis 36.9%. Acite form sinusitis 12.8%, chronic 87.2%. In Blondeau Hirlz film: dim image of ethmoid sinus 96.4%, maxial sinus 60.6%, sphenoid sinus 24.2%, frontal sinus 5.2%. Complications occurred in 48.7%, the common were inflammation of the throat 27.2%, media otitis 21.9%. Within one year, the complication occurred in 35.8%, more 1 year 58%

Patients with the microbial hepatic abscess in the digestive department of Viet Tiep hospital during 1995-1999 participated to a study. The methods included the clinical examination, hematologic tests, X-ray, ultrasound and pus test. The results have shown that fever: 100%, hepatodynia: 75%, hepatomegaly and hepatodynia: 50%, eye yellow: 50%, positive hepatic shaking: 41%, anemia: 41%, the moderate and severe anemia: 58.2%, leucocyte of 9.1x10g/l: 91.6%, increase of total bilirubine: 50%, plus had a offensive smell suspected due to anaerobic microorganism: 33.34%, 1 focus of abscess: 10 patients; 2 focuses of abscess: 2 patients, the shortest duration of treatment: 5 days and longest duration of treatment: 31 days. The conclusions: the clinical and paraclinical features suggested the microbial hepatic abscess; treatment by high effective antibiotics and needle aspiration of plus; the surgical treatment for cases with many focus of abscess.

Infant with high risk of Clifford syndrome was predicted by mean of amniotic fluid index (AFI) measurement before labor. There is reliability by underwent ultrasound evaluation for AFI measurement with modified four quadrant techniques before labor. 287 pregnant women were involved in this study. Authors found that: A high negative linear regression correlation between AFI and gestational age 38 to 42 weeks. After 38 weeks the AFI appeared to decline gradually the mean AFI was 144+/-40 in 38 weeks and 88+/-35 in 42 weeks of gestational age. There is a high relationship between Clifford syndrome and AFI. The cut-off point AFI <=40 as a predictor for predicting the fetal outcome related Clifford syndrome with the positive predictive value = 90. The negative predictive value: 98.2%. The specificity predictive value 99% and the positive predictive value: 64%.

Cloning and determining the nucleotide sequence and expression of human erythropoietin (h-epo) gene in E. coli cells were presented. A gene encoding for mature h-EPO was amplified from human kidney total RNA by RT-PCR using specific primers. The product was cloned into the pCR2.1 TOPO cloning vector and the nucleotide sequence containing 498 bp encoding for mature h-EPO with 166 amino acids was determined by ABI PRISM 3100 Avant Genetic Analyzer (Applied Biosysterms). To express h-EPO in E.coli cells, the h-epo gene was subcloned into the pET21 (+) vector (Novagen) by ligase reaction and was transformed into BL21 (DE3) cells. The cells harboring the recombinant plasmid were grown in liquid LB medium supplementing ampicillin (final concentration of 100g/ml) at 370C. When the OD600 nm of the culture reached 0.5, IPTG (final concentration of 0.4mM) was added. The expression of the h-EPO was analyzed by SDS-PAGE and confirmed by Western Blotting using anti-h-EPO antibody

Study 58 high pressure patients at Central Army Hospital 108 and 38 healthy and old people. The result was: QT gap is QTd87+-42ms, Qtcmax 485+-51, QT cd96+-33ms and QTc 443+-25ms longer comparing with 40+-13ms, 452+-45ms, 66+-10ms, 410+-27ms of normal people. QTd, QTcd, QTc in these patients initially incur hyperthropy of left vertricle, diostole and systole disorder which is taking longer than high pressure patients do not incur hyperthropy of left vertricle, diostole and systole disorder. Inverse relations between QTc and E/A index and direct proportion between QTd, Qtc and LVM, LVMI indices

The study was designed and conducted from April 2004 to November 2005 to assess the infection of intestinal protozoa in school children. A total of 652 stool samples of school children in three schools from different geographical places of Ninh Binh (Red River Delta), Phu Tho (foot hill area) and Ha Giang (northern mountainous) was examined by etherformalin (WHO recommended technique). A general prevalence of protozoa of 19.01%, of which the individual infection rates of 22.96%, 13,18%, and 21.07% were found in Ninh Binh, Phu Tho and Ha Giang, respectively. The protozoa species such as E.histolytica; E.coli; E.nana; E.hartmanni (belonging Amoeba) were more commonly found (11.8%) while G.lambia (Flagellata) was less (5.9%). Oocyst was rare (2.1%) and no case of Cryptosporidium was found.

Background: AH product is a herbal remedy containing of twelve plant extracts, which has a good hepatoprotective effect in two models inducing acute liver injury by carbon tetraclorid (CCl4) and paracetamol. Objective: To evaluate antioxidant activity in vitro and in vivo of AH product. Subjects and methods: Evaluation of antioxidant activity through a reduction of anion superoxide level in vitro and MDA concentration in liver tissue in vitro and in vivo. Results: AH product reduced anion superoxide level, IC50 was 26.60\xb5g/ml. In vitro, AH product at concentration of 125\xb5g/ml reduced formation of MDA 53.70%. The higher the concentration, the stronger the inhibition. In vivo, models of acute liver injuries induced by CCI4 and PAR in mice, AH product at two different doses (4.8 tablets/kg and 9.6 tablets/kg) reduced MDA concentration in liver tissue (33,9 - 36,6 % in CCI4 model and 21,4 - 25,3 % in PAR model) in comparison with group which used hepatotoxins but didn't use any drug. Conclusions: AH product containing many remedies was demonstrated having antioxidant activity which contributed to mechanism of hepatoprotection of this product. \r\n", u'\r\n', u'

Background: Sciatic neuralgia syndrome is a quite common condition in clinical of internal medicine diseases. The syndrome is not life threatening but reduce the ability to work and activities of the patients. The disease is more common in men than women and most of working age.\r\n', u'Objectives: To define the clinical characteristics of sciatic neuralgia syndrome. \r\n', u'Subjects and methods: The cross sectional study was carried out on 48 sciatic neuralgia patients aged from 16 to 70, treated at Bach Mai hospital. The research indices were clinical and traditional medicine characteristics of sciatic neuralgia syndrome.\r\n', u'Results: Sciatic neuralgia was common in the 20-39 year old (87.5%) age group. The male to female ratio was 1.7 (p<0.01). The sciatic neuralgia syndrome rose after excessive exercise (50%). In almost hernia cases of vertebral disc on spinal column was detected by MRI (83.3%). The impaired nerve root was L5 (64.6%). Acupuncture sites were on gallbladder meridian (50.0%), bladder meridian (20.8%) and coordinated (29.2%)\r\n', u'Conclusion: The sciatic neuralgia syndrome causing hernia on spinal column was common at 20-59 year old age. The male number was higher than female. Almost sciatic neuralgia patients had noticed pain on the gallbladder meridian (p<0.05).\r\n', u'\r\n', u'
