Objective To study the effects of density,phosphorous(P),and nitrogen(N)fertilizers on yield and quality of Andrographis paniculata.Methods Randomized block design in yield was used and HPLC was used to analyze the content of andrographolide and dehydroandrographolide.Results Plant height,fresh weight,dry weight,content of dehydroandrographolide were influenced significantly by density.The quality character and economic yield of content of andrographolide,dehydroandrographolide,total content of both andrographolide and dehydroandrographolide were significantly influenced by P nutrition.The economic yield of dry weight,content of andrographolide and dehydroandrographolide,and total content of both andrographolide and dehydroandrographolide were influenced significantly or extreme significantly by N nutrition.P and the interaction of P and N fertilizer extremely influenced the economic yield.The relative influences between plant weight and dry weight was extremely significance,that between quality character and quality character,that between quality character and economic yield were significant or extremely significant.Conclusion When planted with 1.8?105 /hm2,fertilizered with P2O5 540 kg/hm2 and pure N 225 kg/hm2,the hightest economic yield is gained.

Objective To evaluate clinical efficiency and quality-of-life outcomes in treatment of severe pelvic organ prolapse by the Xiehe pelvic floor reconstruction surgery. Methods From Jun. 2006 to Dec. 2008, 277 severe pelvic organ prolapse patients with stage Ⅲ to Ⅳ from 8 hospitals in China were enrolled in this prospective study. Pelvic organ prolapse quantitative examination (POP-Q) and anatomic improvement in these patients after surgery were analyzed in this interim study. Comparisons of pelvic floor impact questionnaire-short form 7 (PFIQ-7) and pelvic floor distress inventory-short form 20 (PFDI-20) in these patients before and after surgery was used to evaluate quality of life. Comparison of pelvic organ prolapse-urinary incontinence sexual questionnaire (PISQ) in these patients before and after surgery was used to evaluate quality of sexual life. Results With a median follow-up of 14. 0 months (6 -28 months),twenty-three patients showed recurrent prolapse (8. 3%, 23/277), and anatomical success ( < stage 2 in the treated compartment) was 91.7% (254/277). In this series, mesh exposure or erosion rate was 6. 9% (19/277). The postoperative de novo stress incontinence rate was 6. 5% (18/277). The scores for PFIQ-7 and PFDI-20, and its subscales were significantly improved, the scores of before treatment were lower than those after treatment (P <0. 01 ). And there was no significant difference in the average score of PISQ before and after the surgery (76. 6 ± 15.4 versus 75.5 ± 14. 5 versus 73.6 ± 12. 6, P >0. 05 ), but the rate of de novo dyspareunia was 11% (9/80). Conclusions Xiehe pelvic floor reconstruction surgery was safe and efficacy in treatment of pelvic organ prolapse. It could improve quality of life remarkably with less cost when compared with the traditional total pelvic floor reconstruction surgery.

The CBD gene from Trichoderma reesei was cloned into the Corynebacterium glutamicum secretion expression vector pXMJ19-sp, in which green fluorescent protein was inserted to obtain pXMJ19-sp-GFP-CBD. After induced by 0.5 mmol/L IPTG, GFP-CBD was expressed in Corynebacterium glutamicum at high level of 200 mg/L. The GFP-CBD could be purified to high purity with cellulose column. The results indicated CBD can be successfully used in Corynebacterium glutamicum expression system and thus offer an extremely simple, effective and scalable way for production of recombinant proteins.

Objective To investigate awareness and influencing factors of human papilloma virus (HPV)self-sampling for cervical cancer screening of female in Shenzhen.Methods A total of 544 female,who during July 2014 to June 2015,participated in live and online HPV self-sampling detection organized by our hospital,were surveyed by self-designed questionnaire.Their epidemiological data,HPV and cervical cancer related knowledge,awareness of HPV self-sampling for cervical cancer screening,their attitude,willingness and acceptance to HPV self-sampling for cervical cancer screening were investigated.Effects of awareness of HPV self-sampling to the cervical cancer screening and main influencing factors were analyzed.Results Among the 544 women,47.1% were aware of HPV;22.8% were aware of what diseases could be caused by HPV;12.5%had heard of and done by themselves self-sampling for cervical cancer screening;only 6.3% had heard of and participated in online self-sampling for cervical cancer screening.Women,who were enterprise /corporate white collar/independent enterprise manager or whose monthly income was over 30,000 yuan,were less aware of HPV self-sampling than other women (χ2 =13.058,12.626;P <0.05).81.6% of the female were apparently inclined to be sampled by doctors,and only 7.0% of the female believed that credibility of self-sampling screening was above 80%.The biggest concern about online self-sampling was mainly metamorphic specimens during transport,pollution,etc.Conclusions Awareness of female in Shenzhen about HPV and HPV self-sampling cervical cancer screening are relatively low.Intervention should be emphasized in reliability degree of self-sampling result,discomfort degree of sampling,complexity,specimen preservation,transport and result feedback.

OBJECTIVETo analyze CYP21A2 gene mutation in two families with 21-hydroxylase deficiency (21-OHD) and to explore the correlation between genotype and clinical phenotype.
METHODSTwo patients with 21-OHD and their families were investigated. CYP21A2 gene mutation was analyzed by PCR and direct sequencing.
RESULTSThe probands from family 1 and 2 have been respectively diagnosed with simple virilizing and non-classical 21-OHD. Both showed increased baseline serum 17hydroxyprogesterone, testosterone and adrenocorticotropic hormone (ACTH), but had no evidence of salt loss. Computer tomography revealed bilateral adrenal hyperplasia in both patients. After 1 year treatment, both had conceived successfully. DNA sequencing revealed that the proband of family 1 had compound heterozygous mutations for IVS2 13 A>G and Ile172Asn. Her father was heterozygous for Ile172Asn, whilst her mother and brother were heterozygous for IVS213A/C>G. In family 2, the proband was heterozygous for Arg341Trp and Gln318X. Her father, sister and nephew were heterozygous for Arg341Trp, whilst her mother was heterozygous for Gln318X. her brother and niece were non-affected. Carriers of single heterozygous mutations in both families had no clinical sign.
CONCLUSIONIn both families, the disease has been caused by compound heterozygous mutations, for which there has been a good genotype-phenotype agreement. Screening of CYP21A2 gene can facilitate both diagnosis and genetic counseling.

Pseudomonas aeruginosa is one of the common multidrug-resistant bacteria in the clinic. Because it can produce a "protective" biofilm, it can affect the penetration and killing efficacy of antibacterial drugs, leading to the formation of a persistent and persistent chronic infection in the host. Biofilms make Pseudomonas aeruginosa resistant to antibacterials and evasive to the host′s immune system. Therefore, traditional conventional antibacterials are difficult to achieve effective bactericidal treatment. Understanding the process of P. aeruginosa biofilm formation and the regulatory mechanisms that affect biofilms can provide ideas and methods for our future research on new antibacterial drugs.
