Objective To study and analyze the clinical efficacy of compound preparation Femoston for the treatment of perimenopausal syndrome in women. Methods 60 women with perimenopausal syndrome from April 2016 to July 2017 were selected and randomly divided into the control group and the experimental group, 30 cases for each group. The control group was given estradiol valerate tablets, and the experimental group was treated with compound preparation Femoston, one tablet a day. The treatment time of the two groups was 6 months, and the clinical efficacy of the experimental group and the control group were compared and analyzed. Results After the corresponding treatment, 4 patients were ineffective in the experimental group. In the control group, 7 patients were ineffective, 10 cases were effective, and 13 cases were good effective. The effective rate of the experimental group was 86.67%, which was significantly higher than that (76.67%) of the control group with statistical significance (P<0.05). The level of FSH in the experimental group was (24.10 ± 15.24) U/L, which was significantly better than that of the control group (42.72 ±15.56) U/L with statistical significance (P<0.05). There were no obvious adverse reactions in the two groups, and the rate of adverse reactions such as vomiting, abdominal pain and breast pain were 3.33% and 6.67%, respectively, and there was no statistical significance. Conclusion The clinical efficacy of compound preparation Femoston for treating perimenopausal syndrome is ideal. Femoston could significantly improve the hormone levels in patients with high safety.

The chemical constituents from the n-butanol fraction of ethanol extract of safflower (Carthamus tinctorius L.) were isolated and purified using chromatographic process including MCI Gel CHP-20, ODS, Sephadex LH-20 column chromatography, and semi-preparative HPLC method, and one alkyne and two phenylpropanoid derivants were obtained. Their structures were identified as (5R,E)-tetradecane-12-ene-8,10-diyne-1,5,14-triol (1), (E)-8-O-β-D-glucopyranosyl n-butyl cinnamate (2), and (7S,8S)-7-(4-hydroxy-3-methoxybenzene)-7-butyl-8,9-diol (3) by modern spectroscopy methods (1D NMR, 2D NMR, UV, IR and MS). 1-3 are all new compounds. Compounds 1-3 were screened for their anti-renal fibrosis activities in vitro, and none of them showed obvious effect.

Aim: To investigate the androgen receptor (AR) isoform expressions in human prostatic cancer tissue and LNCaP cell line. Methods: With high resolution isoelectric focusing (IEF) method we demonstrated the different expressions of AR isoforms in human prostatic cancer tissues and LNCaP cell line. Results: Data were obtained from three prostatic cancer specimens and the LNCaP cell line. Three types of AR isoforms were detected with pI values at 6.5,6.0, and 5.3. For the 3 prostatic cancer specimens, 1 sample showed all the three types of AR isoforms, the second specimen expressed at 6.5 and 6.0, and the third failed to show any type of isoforms. The LNCaP cell line expressed all the three AR isoforms. Binding of 3H-dihydrotestosterone (3H-DHT) to these three isoforms was inhibited by the addition ofl00-fold excess of DHT or testosterone, while not by progesterone, oestradiol and diethylstilboestrol. Conclusion: The expression of AR isofonns is different in different prostate cancer tissues, which may be related to the difference in the effect of anti-androgen therapy in different patients.

Abstract: Objective To investigate the differences in epidemiological and clinical characteristics of patients with spotted fever (SF) and severe fever with thrombocytopenia syndrome (SFTS). Methods A total of 86 patients with SF and 113 patients with SFTS who were laboratory-confirmed in the second-level and above hospitals in Lu'an City from January 2017 to January 2022 were selected. The basic data, epidemiological history, clinical data and laboratory test results of the two diseases were retrospectively analyzed for comparison. Results The proportion of male in SF group was 32.56% (28/86), and the proportion of male in SFTS group was 53.98% (61/113), the difference was statistically significant (χ2=9.067, P<0.01). The proportions of abdominal pain and diarrhea in the SF group were (3.49%, 3/83) and (21.24%, 24/113), which were significantly lower than corresponding (6.98%, 6/86) and (46.90%, 53/113) in the SFTS group (χ2=13.121, 37.322, P<0.01). The incidences of rash and eschar in SF group were 95.35% (82/86) and 20.93% (18/86), which were significantly higher than corresponding 1.77% (2/113) and 0.88% (1/113) in SFTS group (χ2=175.311, 22.721, P<0.01). The levels of leukocytes, platelets and C-reactive protein in the SF group were significantly higher than those in the SFTS group, and the levels of transaminase, lactate dehydrogenase and D-dimer were significantly lower than those in the SFTS group, and the differences were statistically significant (all P<0.05). Conclusions The rash and inflammatory reaction are more obvious in SF patients, while the liver function, myocardial function and coagulation function are significantly impaired in SFTS patients.

OBJECTIVETo develop a rapid method for the detection of Down syndrome (DS) using dual-color competitive quantitative fluorescent polymerase chain reaction (DCC-QF-PCR), and to assess its feasibility for the prenatal diagnosis of Down syndrome.

METHODSDNA was extracted from peripheral blood of 30 DS patients and 60 normal men, common primers for DSCR and USC2 genes and respective TaqMan probes were designed and synthesized. The results of DCC-QF-PCR were compared with those of QF-PCR which measured the ratio between DSCR and GAPDH. Forty-six amniotic fluid samples were assayed with DCC-QF-PCR. The results were compared with that of karyotyping. Monoclone fragments for DSCR and USC2 genes were obtained from direct cloning of PCR products. DCC-QF-PCR was carried out using different DNA ratios of DSCR and USC2 as the template. The dosage ratio between DSCR and USC2 was calculated.

RESULTSThe gene dosage ratio of the DS patients was 1.41-1.74, which was significantly higher than that of normal men (0.93-1.15). The dosage ratio range of DSCR and GAPDH by QF-PCR was comparatively greater than that of DSCR and USC2. Three samples were diagnosed as DS, which was in good agreement with that of karyotyping analysis. There was no significant difference between the gene dosage ratio from DCC-QF-PCR and that of predetermined (P>0.05).

CONCLUSIONDCC-QF-PCR is an accurate, rapid, and low cost method, which only requires tiny amount of sample and therefore has broad application in the genetic and prenatal diagnosis.

To identify whether a highly repeated GT sequence from DCA1 promoter from Dunaliella salina,which have been proved to be a salt-inducible promoter in our previous study,would be a salt-inducible regulation element,different primers were designed to amplify 6 different-length fragments of DCA1 promoter from D.salina by PCR.After these fragments were respectively inserted into the HindⅢ-BamH I sites of the vector pU?GUS,serial expression vectors containing the gus gene were generated.D.salina cells transformed with these recombinant plasmids by electroporation were grown in liquid media containing different concentrations of sodium chloride respectively.GUS enzyme activity was measured histochemically and fluorometrically.The results revealed that 3 fragments containing GT repeated sequence drove the external gus gene expression and the expression pattern of the gus gene was regulated by the concentrations of sodium chloride.Additionally,the 2 fragments without tandem GT sequence drove the gus gene expression,but the expression pattern of the gus gene wasn't regulated by the concentration of sodium chloride;Also,the upstream fragment of the tandem GT sequence wasn't able to drive the gus gene expression.In conclusion,the highly repeated GT sequence from the DCA1 promoter plays an important role in the salt-inducible regulation of DCA1 promoter from D.salina and might be a novel salt-inducible element.

Objective To investigate the effects of ultraviolet blood irradiation and oxygenation(UBIO)on oxygen free radical metabolism(OFRM)in rabbits with acute soman intoxication.Methods One hundred rabbits were randomly divided into five groups:a control group,a soman intoxication group(I),a soman intoxication plus routine therapy group(TR),a soman intoxication plus UBIO therapy group(UBIO)and a soman intoxication plus complex therapy group(CT).All the rabbits were intervened accordingly.Then the concentrations of malondiade- hyde(MDA)and the activities of superoxide dismutase(SOD),glutathionperoxidase(GSH Px)and catalase (CAT)in serum were determined at 14 d after various treatments.Results Compared with the control group,the concentration of MDA and the activity of CAT in the 1 group were significantly increased(P＜0.01),while the activi- ties of SOD and GSH Px were obviously decreased(P＜0.05).After UBIO or complex therapy,the serum level of MDA was significantly decreased in comparison with that in the I group(P＜0.01),while the concentrations of SOD, GSH Px and CAT were enhanced(P＜0.05).Conclusion UBIO therapy can improve antioxidation activity against the injury caused by free radicals and could be used to treat acute soman intoxication,which causes injury from in- creased oxygen free radical concentrations.
