BACKGROUND: The combination of electric acupuncture and clomipramine is the behavior attempt in the integration of Chinese and western medicine in the treatment of obsession.OBJECTIVE: To probe into the long-term therapeutic effects of the combination of acupuncture and medication on obsession and its influence on social functional recovery.DESIGN: Controlled study with observation in which the patients were taken as the objects.SETTING: Wards of a municipal mental hygiene center PARTICIPANTS: The research was performed in the Fifth People's Hospital of Zibo. Totally 30 inpatients were selected from January 1997 to October 2003 in the hospital, aged varied from 18 to 57 years, at the average of (33 ± 12) years. Thirty patients were divided randomly into two groups,named as experimental group, 15 cases with 8 males and 7 females; and the control group, 15 cases with 7 males and 8 females.METHODS: In the experimental group, electric acupuncture was applied on neiguan, renzhong and chengjiang, together with clomipramine orally. In the control group, only clomipramine was applied. The therapeutic effects and side effects were evaluated with Y-Bocs, TESS and clinical evaluation standards successively before the treatment, at the 4th, 6th and 8th weekends after treatment and by 6 months following visits. SDSS evaluation was carried on at the 8th week of the treatment.MAIN OUTCOME MEASURES: Comparisons of evaluating results with Y-Bocs, TESS and SDSS.RESULTS: At the 4th, 6th and 8th weekends of the treatment, the score-reducing rates of Y-Bocs in the experimental group were higher than those in the control group, but the difference was not significant ( P ＞ 0.05). The scores of TESSin the control group were remarkably higher than those in the experimental group( P ＜ 0. 01 ) . Factor scores of "profession and work" in SDSS in the experimental group were lower than that in the control group ( P ＜ 0.05 ).CONCLUSION: Electric acupuncture on neiguan, renzhong and chengjiang reduces the side effect of clomipramine in the treatment of obsession and improve the living quality of the patients with obsession.

Verruciform xanthoma is an uncommon benign lesion. The most common presentation occurs in the oral cavity; however, it has also been described in other sites, especially the penis. Herein is reported the first case of verruciform xanthoma of the penis in China, the fourteenth case in the literature. Clinically, genital verruciform xanthoma is often confuses with papillomas, verrucous carcinomas and squamous cell carcinomas, and therefore a histopathological diagnosis is necessary.

OBJECTIVETo investigate the effect of Zilongjin (ZLJ) on human androgen-dependent type of prostate cancer cell line LNCaP.

METHODSMTT assay, flow cytometry and fluorescence microscopy were used to observe the effect of ZLJ in anti-proliferation, cell cycle arresting and apoptosis induction. RT-PCR was used to examine the effect of ZLJ on expressions of prostate marker gene (PSA), androgen receptor (AR), apoptosis related genes (bcl-2 and bax), and Western blot assay was used to detect the effect on protein expression of bcl-2 and bax.

RESULTSZLJ could cause apparent inhibition on proliferation, induce G0/G1 phase arresting and apoptosis in time- and dose-dependent manner on LNCaP cells. The concentration for inhibiting cell growth by 50% (IC50) in 72 hrs was 0.79 mg/ml. ZLJ could down-regulate the expression of PSA, AR, bcl-2 genes and lower bcl-2 protein expression, but showed ineffective on bax protein expression.

CONCLUSIONZLJ displays its anti-tumor effects by way of inhibiting the cell proliferation, arresting the G0/G1 phase, inducing apoptosis, down-regulating PSA, AR, bcl-2 gene expression and lowering bcl-2 protein expressions.

Objective: To analyze the genotype diversity and phylogenetic characterization of norovirus(NoV) in patients with diarrhea from Anhui province. Methods: NoV positive fecal specimens from sentinel hospitals were collected from January, 2016 to December, 2017. The samples were detected by Real-time fluorescent quantitative PCR. Positive samples were of randomly selected and amplified by RT-PCR and the products were sequenced. Phylogenetic tree was constructed by the Neighbor-Joining method based on partial VP1 gene regions of NoV to perform phylogenetic analysis. Results: A total of 263 NoV positive samples were genotyped, of which 239 belonged to genogroup II, 24 belonged to genogroup I. Fifty-five positive samples were successfully sequenced. There were 6 NoV GII genotypes, which included GII.2, 3, 4/Sydney_2012, 13, 17 and 21, while NV GII.17 and GII.4 were the dominant genotypes from 2016 to 2017. The predominant genotype was GII.4/Sydney 2012 (47.27%, 26/55), followed by GII.17 (23.64%, 13/55) and GII.2 (14.55%, 8/55). Phylogenetic tree showed that 26 strains belonged to genotype GII.4/Sydney 2012, NoV. The nucleotide homology among the 26 VP1 genes was 97.8% to 100%. Analysis of the partial VP1 genes of 26 strains showed that it shared the highest homology of 98.9% with the strain of GII.4Sydney2012 (GenBank ID: KU720515). However, the prevailing genotype in the Anhui province has shifted on two separate occasions, the GII.17 strain was dominant in 2016, and the GII.4/Sydney 2012 strain was dominant in 2017. Conclusions NoV GII was the major pathogen causing sporadic diarrhea in Anhui province during from 2016 to 2017, the genotypes are widely distributed, and shifted into the two predominant strains.

Metabolomics, which mainly studies the metabolite components of organisms, tissues, cells and their dynamic changes, is an emerging omics technology following genomics and proteomics. Metabolites are the final products of cellular regulation, and the concentration of metabolites is considered to be the ultimate response of a biological system to genetic or environmental changes. Secondary metabolites with chemical diversity are widely present in living organisms, thus accurate quantification of secondary metabolites through appropriate analytical platforms is an important task of metabolomics. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) is the most commonly used method for the detection of metabolites, providing a basis for the wide application of plant secondary metabolites. This review summarizes the advances of using LC-MS/MS techniques for the detection of phytohormone, folic acid, flavonoids and other secondary metabolites.
