Heterozygous CARD9 mutation favors the development of allergic bronchopulmonary aspergillosis / 中华医学杂志(英文版)

BACKGROUND@#Previous research demonstrated that a homozygous mutation of g.136372044G>A (S12N) in caspase recruitment domain family member 9 ( CARD9 ) is critical for producing Aspergillus fumigatus -induced ( Af -induced) T helper 2 (T H 2)-mediated responses in allergic bronchopulmonary aspergillosis (ABPA). However, it remains unclear whether the CARD9S12N mutation, especially the heterozygous occurrence, predisposes the host to ABPA.@*METHODS@#A total of 61 ABPA patients and 264 controls (including 156 healthy controls and 108 asthma patients) were recruited for sequencing the CARD9 locus to clarify whether patients with this heterozygous single-nucleotide polymorphisms are predisposed to the development of ABPA. A series of in vivo and in vitro experiments, such as quantitative real-time polymerase chain reaction, flow cytometry, and RNA isolation and quantification, were used to illuminate the involved mechanism of the disease.@*RESULTS@#The presence of the p.S12N mutation was associated with a significant risk of ABPA in ABPA patients when compared with healthy controls and asthma patients, regardless of Aspergillus sensitivity. Relative to healthy controls without relevant allergies, the mutation of p.S12N was associated with a significant risk of ABPA (OR: 2.69 and 4.17 for GA and AA genotypes, P = 0.003 and 0.029, respectively). Compared with patients with asthma, ABPA patients had a significantly higher heterozygous mutation (GA genotype), indicating that p.S12N might be a significant ABPA-susceptibility locus ( aspergillus sensitized asthma: OR: 3.02, P = 0.009; aspergillus unsensitized asthma: OR: 2.94, P = 0.005). The mutant allele was preferentially expressed in ABPA patients with heterozygous CARD9S12N , which contributes to its functional alterations to facilitate Af -induced T H 2-mediated ABPA development. In terms of mechanism, Card9 wild-type ( Card9WT ) expression levels decreased significantly due to Af -induced decay of its messenger RNA compared to the heterozygous Card9S12N . In addition, ABPA patients with heterozygous CARD9S12N had increased Af -induced interleukin-5 production.@*CONCLUSION@#Our study provides the genetic evidence showing that the heterozygous mutation of CARD9S12N , followed by allele expression imbalance of CARD9S12N , facilitates the development of ABPA.

Trocar-site hernia after gynecological laparoscopic surgery: a 20-year, single-center experience / 中华医学杂志(英文版)

BACKGROUND@#Trocar-site hernia (TSH) is a serious complication after laparoscopic procedures. Although it is a rare entity, it can have life-threatening consequences. This study aimed to retrospectively analyze the potential associated factors for TSH following gynecologic laparoscopy and summarize prevention strategies based on our experience.@*METHODS@#We searched for gynecological laparoscopic surgeries in the medical records system of Peking Union Medical College Hospital (PUMCH) from August 1998 to July 2018 and further sifted through the results for cases involving TSH. All included patients were divided into different groups according to patient characteristics, and the rate of TSH was compared among groups. Moreover, the detailed information of all patients with TSH was recorded and analyzed. Statistical analyses were performed with GraphPad Prism 6.@*RESULTS@#The approximate total rate of post-operative TSH among gynecologic laparoscopy procedures performed at PUMCH in the last 20 years was 0.016% (9/55,244). The rate of TSH was significant higher in elder patients (≥60 years old; 3/2686, 0.112%) than in younger patients (<60 years old, 6/52,558; 0.011%, P = 0.008). Moreover, the approximate rate of TSH was significantly higher after single-incision laparoscopic surgery (SILS, 2/534, 0.357%) than conventional laparoscopic surgery (7/54,710, 0.013%, P = 0.003). The average age of patients with TSH was 53.4 years (range, 35.0-79.0 years). Two of the nine patients had late-onset TSH following SILS; the other seven had early-onset TSH following conventional laparoscopy. Five TSH cases occurred at right lateral port sites, and the remaining three occurred at the umbilical port site. All patients underwent repair surgery, and one required small bowel resection.@*CONCLUSION@#Older age and SILS are potential associated factors for TSH development, while reducing excessive manipulation and improving suturing skills, especially at the umbilical trocar site following SILS and the right lateral trocar site, can avoid herniation.

Manometric comparison of anorectal function after posterior vaginal compartment repair with and without mesh / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Although repair augmented with mesh has been proved its priority in anatomical and functional recovery after anterior compartment reconstruction, the data about posterior compartment are scarce. The aim of this study was to compare bowel functional outcome of posterior vaginal compartment repair with and without mesh in patients with pelvic organ prolapse (POP).</p><p><b>METHODS</b>This was a prospective, double-blind, clinical pilot study of 22 postmenopausal women with symptomatic POP (overall POP-quantification [POP-Q] Stage III-IV) who underwent total pelvic floor reconstruction. Patients were grouped according to the use of mesh for posterior vaginal compartment repair: A mesh group and a nonmesh group. POP-Q stage, the pelvic floor impact questionnaire short form-7 (PFIQ-7) and anorectal manometry were evaluated before and 3 months after surgery. Anatomical success was defined as POP-Q Stage II or less. A t-test was used to compare preoperative with postoperative data in the two groups.</p><p><b>RESULTS</b>Totally, 17 (71%) were available for the follow-up. POP-Q measurements improved significantly compared to baseline (P < 0.05) in both groups. No recurrence was observed. Subjects in both groups reported improvement in pelvic floor symptoms, and there was no significant difference in the PFIQ-7 score between groups at follow-up (P > 0.05). Compared with baseline, the nonmesh group exhibited a statistically significant decrease in anal residual pressure, a significant increase in the anorectal pressure difference during bowel movement, and a reduced rate of dyssynergia defecation pattern (P < 0.05).</p><p><b>CONCLUSIONS</b>Provided there is sufficient support for the anterior wall and apex of vagina with mesh, posterior compartment repair without mesh may be as effective as repair with mesh for anatomical recovery while providing better anorectal motor function.</p>

Dual role of transcription factor AP-2 in carcinogenesis / 浙江大学学报·医学版

Activating protein-2 (AP-2) is a cell type-specific DNA binding transcription factor family with the ability to regulate the expression of specific target genes. Five isoforms of AP-2 have been discovered, they are AP-2alpha, AP-2beta, AP-2gamma, AP-2delta and AP-2epsilon. AP-2s are involved in the regulation of cell proliferation, differentiation and apoptosis as well as embryogenesis of mammary animals. Recently, the function of AP-2 in neoplasm has attracted increasing attention. Researches reveal that the modulation of AP-2 in tumorigenesis may be dual, either inhibitory or promoting, which depends on the specific tissues,stages of cancer progression and difference between five family members. This review summarizes recent research progress on the role of AP-2 in the oncogenesis and their potential applications in clinical practice.

Effect of ginsenoside Rh2 on immunocompetence of alveolar macrophages in patients with non-small cell lung cancer / 中南大学学报(医学版)

OBJECTIVE@#To explore the effect of ginsenoside Rh2 (G-Rh2) on the excretion of cytotoxin-effecting molecule of alveolar macrophages (AM) in patients with non-small cell lung cancer (NSCLC).@*METHODS@#The concentration of tumor necrosis factor (TNF-alpha) and NO in the bronchoalveolar lavage fluid (BALF) and the cultured supernatants of AM in 35 patients with NSCLC were measured by ELISA and enzyme method,and levels of TNF-alpha and NO in the cultured supernatants of AM after being cultivated with IFN-alpha, G-Rh2, and IFN-alpha+G-Rh2 were measured by the same method.@*RESULTS@#AM in all the non-small cell lung cancer patients produced TNF-alpha and NO. The activity of TNF-alpha and NO was lower in the BALF and in the cultured supernatants of AM of the tumor-bearing lungs than that of the non-tumor-bearing lungs. The concentrations of TNF-alpha and NO in the cultured supernatants of AM cultivated with G-Rh2 were higher than those in the control (P0.05). The concentrations of TNF-alpha and NO in the cultured supernatants of AM cultivated with both G-Rh2 and IFNalpha were obviously higher than those stimulated with IFNalpha or G-Rh2 (P<0.01) alone.@*CONCLUSION@#G-Rh2 can enhance the excretion of cytotoxin-effecting molecules of AM in patients with NSCLC. The changes are more distinctive when G-Rh2 and IFNalpha have coordinated action.
