Pelvic inflammatory disease sequela (chronic pelvic inflammation) is one of the diseases that affect women's health conditions, and leads to large economic burden. Chinese Material Medica (CMM) plays an impor-tant role in treating pelvic inflammatory disease sequela (chronic pelvic inflammatory). However, due to the lack of Evidence-based Pharmacoeconomic Evaluation Technical Essentials of CMM in Treatment of Pelvic Inflamma-tory Disease Sequela (Chronic Pelvic Inflammatory), non-standard phenomenon often appears in the research liter-ature, such as the selection of research methods, viewpoint of research, determination of cost, effect and utility. Thus, the publish of Evidence-based Pharmacoeconomic Evaluation Technical Essentials of CMM in Treatment of Pelvic Inflammatory Disease Sequela (Chronic Pelvic Inflammatory) is essential for the pharmacoeconomic evalua-tion of CMM in treating pelvic inflammatory disease sequela (chronic pelvic inflammatory).

Objective:
To examine the causal relationship between endometrial cancer and breast cancer using bidirectional two-sample Mendelian randomization (MR) approach.
Methods:
Genetic association data of endometrial cancer were collected through a meta analysis, including 54 884 participants and 9 464 330 single nucleotide polymorphisms (SNPs), and genetic association data of breast cancer were collected through the Breast Cancer Society Consortium, with 228 951 participants and 10 680 257 SNPs. A forward MR analysis was performed using the inverse variance weighted (IVW) method with 8 endometrial cancer-associated SNPs as instrumental variables and breast cancer as the study outcome, and a reverse MR analysis was performed with 112 breast cancer-associated SNPs as instrumental variables and endometrial cancer as the study outcome. The heterogeneity was assessed using the Cochran's Q test, the horizontal pleiotropy was assessed using the MR-PRESSO test and MR-Egger regression, and the robustness of the results was verified with the leave-one-out.
Results:
Forward MR analysis results showed that patients with genetically predicted endometrial cancer had an increased risk of breast cancer compared to those without endometrial cancer (OR=1.083, 95%CI: 1.037-1.132). Reverse MR analysis showed that patients with genetically predicted breast cancer had an increased risk of endometrial cancer compared to those without breast cancer (OR=1.070, 95%CI: 1.010-1.134). Cochran's Q test detected no heterogeneity (P>0.05), and neither the MR-PRESSO test nor the MR-Egger regression revealed horizontal pleiotropy of instrumental variables (both P>0.05). Leave-one-out analysis showed robustness of the MR analysis results.
Conclusion
There are bidirectional causal relationship between endometrial cancer and breast cancer.

Objective To investigate genetic characteristics of Neisseria gonorrhoeae (N.gonorrhoeae) isolates from Guangzhou city in 2014,and to analyze the relationship of N.gonorrhoeae multi-antigen sequence typing (NGMAST) sequence types (STs) with ciprofloxacin resistance.Methods An agar dilution method was used to determine the minimal inhibitory concentration (MIC) of ciprofloxacin in 97 N.gonorrhoeae isolates from Guangzhou city.PCR was performed to amplify the gyrA,parC,porB and tbpB genes from these isolates,followed by gene sequencing and determination of NG-MAST STs.Results Of the 97 N.gonorrhoeae isolates,95 (97.9%) were resistant to ciprofloxacin,including 41 high-level (MIC ≥ 16 mg/L) and 54 low-level (1 mg/L ≤ MIC < 16 mg/L) resistant strains.Mutations were detected at codons 91 and 95 encoding serine in the gyrA gene of all the 95 ciprofloxacin-resistant strains,and in the parC gene of 93 resistant strains.The frequency of the mutation at codon 87 in the parC gene was 85.4% (35/41) in high-level resistant strains,significantly higher than that in low-level resistant strains (59.3%[32/54],x2 =7.64,P < 0.05).MAST STs were successfully determined for all the 97 N.gonorrhoeae isolates except 1 isolate with incorrect PCR amplicons.Of the 96 genotyped isolates,50 were assigned to 35 known STs by using the NG-MAST website (www.ngmast.net),among which,10 STs each contained 2 to 4 isolates.The most common ST was ST5309.Phylogenetic tree analysis revealed that the 96 genotyped N.gonorrhoeae isolates could be classified into 2 groups,and the proportion of isolates with MIC ≥ 16 mg/L is 46.4% (39/84) in group 1,but only 1/12 in group 2 (x2 =6.27,P=0.012).Conclusions High-level resistance of N.gonorrhoeae to ciprofloxacin may be mainly associated with the mutation at codon 87 in the parC gene.NG-MAST STs may be related to the degree of ciprofloxacin resistance.
