A method for simultaneous determination of the shikonin, acetyl shikonin and β, β'-dimethylpropene shikonin in Onosma hookeri and the chromatographic fingerprint was estabished by HPLC-DAD on an Agilent Zorbax SB-column with a gradient elution of acetonitrile and water at 0.8 mL x min(-1), 30 degrees C. The quality assessment was conducted by comparing the content difference of three naphthoquinone constituents, in combination with chromatographic fingerprint analysis and systems cluster analysis among 7 batches of radix O. hookeri. The content of the three naphthoquinone constituents showed wide variations in 7 bathces. The similarity value of the fingerprints of sample 5, 6 and 7 was above 0.99, sample 2 and 3 above 0.97, sample 3 and 4 above 0.90, and other samples larger than 0.8, which was in concert with the content of three naphthoquinone constituents. The 7 samples were roughly divided into 4 categories. The results above indicated that the using of this medicine is complex and rather spotty. The established HPLC fingerprints and the quantitative analysis method can be used efficiently for quality assessment of O. hookeri.

BACKGROUND: The author surveyed and analyzed the changes of perception and satisfaction about family medicine. So that the outcome may bring us a reference to advance family medicine more. METHODS: 247 in and out patients in one general hospital in Seoul were surveyed by the questionnaire from July 26, 2000 to June 20. The date was analyzed statistically by SAS program. RESULTS: As for the knowledge of family medicine, 61.5% of the patients answered that they knew what it is, and the most of them, 54%, via medical institution. The office workers, married , and highly educated people tend to know more about family medicine (P<0.05). As for attitude, 68% of the group answered that family medicine is necessary, because "family medicine doctors give proper advice and consult through out all fields of medicine"(58.8%). As for the preference so prirate doctor, 56.7% of the group answered that they would register for family medicine clinic, and students and office workers are fond of family medicine(P<0.05). As for the satisfaction, 34.4% were ever been to family medicine clinic, and 35.5% out of them were dissatisfied, mainly due to the lack of knowledge of physicians about their diseases(70.1%). CONCLUSION: The perception of family medicine are still scanty compared to the old studies.

The follicular fluid (FF) of ovary contains various biological active products which affected on the growth of follicles and the fertilization of oocyte in physiological reproductive process of mammals. This study was designed to determine the effects of human FF on fertilization of oocyte and embryonal development in vitro culture. The FF was prepared as clear without blood contamination by needle aspiration from mature follicles of human at the time of oocytes retrieval for in vitro fertilization (IVF). As the medium for culture in vitro of embryonal cells, human tubal fluid (HTF) supplemented with follicular fluids at concentrations of 10%, 40% and pure FF were used. These effects were compared to control group of cultured embryos in HTF supplemented with 0.4% BSA (bovine serum albumin). For IVF, 64 eggs in control group, 67 eggs in 10% FF, 57 eggs in 40% FF and 64 eggs in pure FF were respectively allocated. And the rates of fertilization were almost similar in all groups as resulting 82.81% in control, 85.07% in 10% FF, 87.71% in 40% FF and 81.25% in pure FF. On the examination for embryonal cleavage from fertilized eggs, the rates of developing to 4 cell stage was similar in all groups, as results 98.11% in control, 98.27% in 10% FF and 98% in 40% FF but 78.84% in pure FF. And the rates of developing to 8-16 cell stage were significantly reduced as 44% in 40% FF and 44.23% in pure FF (p<0.05) compare to 71.69% in control media. As likewise, the rates of developing to morular stage were also significantly reduced to 36% (p<0.05) and 21.15% (p<0.01) respectively in 40% FF and pure FF And the rates to blastocystic stage of embryo was lowest as 7.69% in pure FF. The quality of embryonal cells on cleavage to the 8-16 cell stage was poorer, higher concentrations of FF The rates of grade 1 in pure FF, as 23.07%, was lowest compare to those of other groups, in which the rates of grade 1 in control, 10% FF and 40% FF were 58.49%, 47.36% and 34% respectively. And on the contrary, the rate of grade 4 in pure FF was highest as 23.07%, while those were 5.66% control, 8.77% in 10% FF and 20% in 40% FF. On the viability of embryos, the rate of embryonal cell death was more rise, at the higher concentrations as well as longer exposure in the follicular fluid. At 48 hours after in vitro culture of embryos, the rate of survival embryos in pure FF was markedly lowered as 44.23%, compare to that of control (p<0.05). But there was not significant difference between the rates of survival embryos in each group beside the pure FF, which the rates were 77.35% in control, 70.17% in 10% FF and 60% in 40% FF respectively. And at 72 hours after in vitro culture, the rates of survival embryos were also significantly dropped to 21.15% in pure and 36% in 40% at concentration of FF compare to 62.26% in control (p<0.05, p<0.01). Finally, the rate of embryonal death at 96 hours after in vitro culture was highest as 82.69% in pure FF among all groups which those were 35.84 in control, 56.14% in 10% FF and 64% in 40% FF respectively. In conclusion, this study suggests that the FF has no effects, in particular, to the in vitro fertilization of oocytes but exerted a bad effect to the cleavage, quality and viability of the embryonal cells during in vitro culture. However, the FF is harmful on embryonal development at conditions in higher concentration and especially on the embryos after 8~16 cell stage.

PURPOSE: Objective of this study is to determine changes in the levels of type I and III collagen in women with stress urinary incontinence (SUI). MATERIALS AND METHODS: Forty-nine women were enrolled to this study and e divided into two groups. Forty-four patients with SUI and 5 patients with without SUI for control. All the women were underwent a pre-operative evaluation. The presence of collagen type I and III was determined by immunohistochemical technique. Analysis of staining was studied with help of specialist of pathology with Image Pro computerized program. The student t-test was used for statistical analysis. RESULTS: Collagen type I and III was significantly reduced (p<0.05) in patients with SUI in anterior vaginal wall tissue. compared to patients in control. Both collagen type I and III were marked reduced in the patient of severe grade of stress urinary incontinence. However there were no significant relation between quantity of collagen and other etiological factors including age, parity, grade, and menopausal. CONCLUSION: In this study, women with SUI have less collagen type I and III around the urethra regardless of the degree of pelvic relaxation, SUI grade, parity, menopausal, age. It appears that collagen has a significant role in the maintenance of urinary continence.

PURPOSE: The aim of this prospective study was to evaluate the effect of metronidazole for wound infection by using intra-incisional infiltration before appendectomy. METHODS: From January to May 2000, 176 patients with acute appendicitis received appendectomy. All patients were randomly divided into two groups. Group I (n=50) was the treatment group and group II (n=126) was the control group. After anesthesizing the patients of group I, 7.5 mg/kg of metronidazole was injected into subcutaneous tissue and muscle. All patients of group I and II were given intravenous injection of cephalosporin and intravenous or intramuscular injection of aminoglycoside. RESULTS: In the 50 cases of group I, the rate of wound infection was 2% and the rate of wound infection in the 126 cases of group II was 4.8%. The rate of anaerobic bacteria of organisms cultured from wound of patients with infection was 0% in group I and 33% in group II. The statistical analysis using chi-square test was not significant (p=0.676) but the rate of wound infection was reduced, especially in infection caused by anaerobic bacteria. CONCLUSIONS: The rate of wound infection was not significant statistically but it was reduced after intra-incisional infiltration of metronidazole. Therefore we suggest that this method can be one of methods that reduce the rate of wound infection after appendectomy.

OBJECTIVETo introduce statistical methods of time trend analysis on cancer rates.

METHODSCancer incidence data collected by the Shanghai Cancer Registry during 1991 to 1999 was used in the analysis to calculate the crude and age-adjusted rates, percent changes (PCs) and annual percent changes (APCs). APCs were estimated by a linear regression of the logarithm on the incidence rates during the nine years. It also introduced a method for partitioning a linear trend in age-adjusted rates into site-specific contributions to the overall floating trend. 95% confidence intervals for the APCs and contributions were described in the paper.

RESULTSA decreasing rates were observed for cancers of stomach and esophagus among both men and women in urban Shanghai from 1991 to 1999. The increasing rates among men would include cancers of colon, rectum, gall bladder, pancreas, prostate, urinary bladder, kidney and leukemia. The rates of cancers among women increased for colon, rectum, lung, breast, gall bladder, endometrium, ovary, urinary bladder and kidney. The changes of above cancers over time were statistically significant (P < 0.05 or P < 0.01), but rates for other cancer sites changed little. The APCs (weighted method) and contributions for the cancers of stomach, esophagus, colon, rectum and prostate were -2.99% and -65.72%, -2.90% and -17.07%, 12.30% and 21.46%, 2.94% and 18.62%, and 3.11% and 15.09% among men, and -6.05% and -39.55%, -1.08% and -35.19%, 2.81% and 28.64%, and 3.69% and 15.70% for the cancers of stomach, esophagus, breast and colon in women, respectively.

CONCLUSIONAPC, and related statistics could be used to describe and analyze the time trend of cancer rates rather than PC or/and graphical method alone.

In this study, we observed the levels of adrenomedullin (ADM) and proadrenomedullin N-terminal 20 peptide (PAMP) in myocardium and aorta of spontaneously hypertensive rats (SHRs) in comparison with Wistar-kyoto (WKY) rats. Contents of ADM and PAMP were measured by radioimmunoassay (RIA) in plasma, myocardium and aorta. The amount of Pro-ADM mRNA of myocardium and aorta was determined by competitive quantitative reverse transcription polymerase chain reaction (RT-PCR). In SHRs the amounts of Pro-ADM mRNA of myocardium and aorta were 66.7% (P<0.01) and 73% (P<0.01) higher than those in WKY rat, respectively. In SHRs, the levels of ADM in plasma, myocardium and aorta were 29%, 76.7% and 79% (all P<0.01) higher than those in WKY rats, respectively. The level of PAMP in SHRs was increased by 42.5% in plasma (P<0.01), 47.2% in myocardium (P<0.0.1) and 27.3% in aorta (P<0.05) compared to WKY rats, respectively. In addition, the ratio of ADM content to PAMP content in SHRs group was increased compared with that in WKY group (2.0+/-0.25 vs 1.64+/-0.3 and 2.2+/-0.18 vs 1.56+/-0.28, in myocardium and aorta, respectively, P<0.01). These results suggest that ProADM gene expression is up-regulated and the increase in ADM and PAMP is different in SHRs. The significance of inconsistency of increase in ADM and PAMP in SHRs needs to be further investigated.

[Objective]To evaluate the expression of enhancer of zeste homolog 2(EZH2),Ki-67 and intratumoral microvaseu?lar density(iMVD)in human colorectal cancer(CRC),and discuss their relationship with the biological behavior and prognosis.[Methods]The expression of EZH2,Ki-67 and iMVD(labeled by CD34 protein)was measured with immunohistochemical MaxVision method in CRC patients followed up over 5 years.[Results]Positive expression rates of EZH2,Ki-67 and iMVD were 40.91%(45/110),57.27%(63/110)and 46.36%(51/110),respectively. EZH2 expression was positively correlated with distant metastasis(P=0.024). Ki-67 expression was positively correlated with tumor size,infiltration depth,AJCC stage and differentiation(P=0.033~0.015). The iMVD expression was positively correlated with infiltration depth ,AJCC stage and differentiation (P=0.016~0.034). Spearman correlation analysis showed that EZH2 expression was positively correlated with Ki-67 expression(r=0.195,P=0.041), whereas negatively correlated with iMVD expression. Ki-67 expression had a positive correlation with iMVD(r=0.213,P=0.025). Multivariate analysis suggested that the EZH2 expression was an adverse independent factor for survivals of CRC patients(HR 1.965, 95%CI:1.019-3.789,P=0.044 for OS).[Conclusion]EZH2 expression was significantly correlate with the proliferation of tumor cells and may plays an important role in the metastasis and prognosis of CRC.
