The management of antibiotic-resistant, bacterial biofilm infections in skin wounds poses an increasingly challenging clinical scenario. Pseudomonas aeruginosa infection is difficult to eradicate because of biofilm formation and antibiotic resistance. In this study, we identified a new benzothiazole derivative compound, SN12 (IC₅₀ = 43.3 nmol/L), demonstrating remarkable biofilm inhibition at nanomolar concentrations in vitro. In further activity assays and mechanistic studies, we formulated an unconventional strategy for combating P. aeruginosa-derived infections by targeting the two-component (Gac/Rsm) system. Furthermore, SN12 slowed the development of ciprofloxacin and tobramycin resistance. By using murine skin wound infection models, we observed that SN12 significantly augmented the antibacterial effects of three widely used antibiotics-tobramycin (100-fold), vancomycin (200-fold), and ciprofloxacin (1000-fold)-compared with single-dose antibiotic treatments for P. aeruginosa infection in vivo. The findings of this study suggest the potential of SN12 as a promising antibacterial synergist, highlighting the effectiveness of targeting the two-component system in treating challenging bacterial biofilm infections in humans.

Objective·To explore EDAR(ectodysplasin A receptor)gene variants that lead to congenital tooth agenesis,and preliminarily analyze the reasons why variants in EDAR can cause both syndromic and non-syndromic tooth agenesis.Methods·Patients with congenital tooth agenesis admitted to the Department of 2nd Dental Center,Shanghai Ninth People's Hospital,Shanghai Jiao Tong University School of Medicine and their family members were included,and genomic DNA from their peripheral blood was extracted for whole exome sequencing(WES).After preliminary screening,PolyPhen-2,Mutation Taster,and Provean were used to predict the harmfulness of potential variants.The screened variants in patients and their families were verified by Sanger sequencing.Conservation analysis of variants was performed,and Swiss-Model was used to analyze the changes in the three-dimensional structure of EDAR.The teeth and syndromic phenotype of the patients and their family members were investigated.Results·Among the included congenital tooth agenesis patients,five patients with EDAR mutations were found,one with EDAR frameshift mutation c.368_369insC(p.L123fs)and the other four with EDAR missense mutations.Two of these four patients were diagnosed as non-syndromic tooth agenesis(NSTA),resulted from c.77C＞A(p.A26E)homozygous mutation and c.380C＞T(p.P127L)heterozygous mutation,respectively.The other two patients with two variants were diagnosed as hypohidrotic ectodermal dysplasia(HED).One compound heterozygous missense mutation patient carried EDAR c.77C＞T(p.A26V)from her father andEDAR c.1281G＞C(p.L427F)from her mother;the other patient with both EDAR and EDA mutations carried EDAR c.1138A＞C(p.S380R)heterozygous mutation and EDA c.1013C＞T(p.T338M)hemizygous mutation.Both variants were from his mother and were reported to be related with NSTA.Two of these missense mutations,EDAR c.1281G＞C(p.L427F)and EDAR c.77C＞A(p.A26E),had not been reported before.The missense mutations affected the protein's spatial conformation by altering the polarity,charge,or volume of the amino acid residues.The frameshift mutation caused a non-triplet base addition,which probably led to protein truncation or degradation.Conclusion·Two new EDAR missense mutations are discovered.An NSTA patients with EDAR homozygous mutations and an HED patient with both EDA and EDAR mutations are reported.It expands the understanding of pathogenic mechanisms of EDAR mutations causing HED and NSTA.

ObjectiveTo explore the effect of Jinshui Xiangsheng prescription on the five-year clinical survival outcome of patients with advanced prostate cancer. MethodFrom May 1, 2014 to May 1, 2016, patients with advanced prostate cancer from Yueyang Hospital of Integrated Traditional Chinese and Western Medicine, Shanghai University of Traditional Chinese Medicine and the Urology Department of the Second Affiliated Hospital of Nanjing University of Chinese Medicine were collected and treated with Jinshui Xiangsheng prescription (155 cases in the observation group). According to age and Gleason score, the patients without Jinshui Xiangsheng prescription were matched in a ratio of 1∶1 (155 cases in the control group). The androgen resistance rate, survival rate, median survival time, and median progress free survival time in 1, 3, 5 years were observed. The prognostic factors of advanced prostate cancer were analyzed and screened out by Chi-square test, t test, Kaplan-Meier and Cox survival analysis. ResultThe androgen resistance rates in the observation group in 1， 3， 5 years were 9.0% （14/155）， 72.3% （112/155）， and 92.9% （144/155）， respectively， and those in the control group were 20.6% （32/155）， 87.7% （136/155）， and 97.4% （151/155）. The 1-year （χ²=8.271，P<0.01）and 3-year （χ²=11.613，P<0.01） androgen resistance rates in the observation group were significantly lower than those in the control group. The median survival time and median progress free survival time in the observation group were （26.35±9.01） months and （11.02±4.40） months， respectively， and in the control group were （22.31±9.21） months and （9.87±5.12） months， respectively. The median survival time and median progress free survival time in the observation group were significantly longer than those in the control group （P<0.05， P<0.01）. The cumulative survival rates in 1， 3， 5 years in the observation group were 96.1% （149/155）， 80.6% （125/155）， and 39.4% （61/155）， respectively， and those in the control group were 94.2% （146/155）， 60.0% （93/155）， and 22.6% （35/155）， respectively. The 3-year （χ²=15.828，P<0.01） and 5-year （χ²=10.201，P<0.01） cumulative survival rates in the observation group were significantly higher than those in the control group. The monofactor analysis showed that the prognostic factors involved in Gleason score， initial prostate specific antigen （PSA）， tumor location， tumor stage， castration regimen， radiotherapy， chemotherapy， complete androgen blockade （CAB）， and Jinshui Xiangsheng prescription （P<0.05， P<0.01）. The multivariate analysis showed that initial PSA， tumor location， and tumor stage were the risk factors affecting the survival time of patients with advanced prostate cancer， whereas Jinshui Xiangsheng prescription， castration regimen， chemotherapy， radiotherapy， and CAB were the independent protective factors affecting the prognosis of advanced prostate cancer. ConclusionJinshui Xiangsheng prescription has a protective effect on the survival of patients with advanced prostate cancer， which reduces the androgen resistance rate and death risk of advanced prostate cancer， thus benefiting the survival of patients. Therefore， it deserves further promotion.

Objective:To investigate the effect of pelvic motion in late pregnancy on the outcome of first trimester delivery.Methods:A total of 127 first-borns admitted to the midwifical clinic of Nanjing Maternal and Child Health Hospital from November 1, 2019 to March 10, 2020 were selected as the research objects, and they were divided into the walking group and the pelvic motion group according to the random number table method. In the end, 62 cases were included in the walking group and 65 cases in the pelvic motion group. The walking group did brisk walking in the third trimester. In the pelvic motion group, the motion in the third trimester consisted of the combined pelvic motion involving the two planes of the upright spine and the horizontal spine, and multiple peripelvic joints. The changes of fertility, birth canal and fetus before and after exercise were observed, and the outcomes of childbirth were compared between the two groups.Results:Indicators reflecting productivity: persistence time of "air bike" on the day before delivery was (27.12±7.73) seconds in the pelvic motion group and (20.56±6.60) seconds in the walking group, the difference was statistically significant ( t value was 5.12, P<0.01). The time of contractions after exercise before delivery was (269.38±123.70) seconds in the pelvic motion group and (591.29±201.82) seconds in the walking group, the difference was statistically significant ( t value was 10.89, P<0.01). The indicators reflecting the situation of the maternal birth canal were as follows: "sitting forward flexion level", pelvic motion group was (33.64±5.91) cm, walking group was (29.50±5.28) cm, the difference was statistically significant ( t value was 4.15, P<0.01). The cervical score during regular contractions was 8.01±1.69 in the pelvic motion group and 7.30±1.40 in the walking group, the difference was statistically significant( t value was 2.56, P<0.05). At the beginning of regular contractions, the proportion of fetal "occipital position" was 93.85% (61/65) in the pelvic motion group and 72.58%(45/62) in the walking group, the difference was statistically significant ( χ2 value was 10.41, P<0.01). The "no pain rate after exercise the day before delivery" was 72.31% (47/65) in the pelvic motion group and 29.03% (18/62) in the walking group, the difference was statistically significant ( χ2 value was 25.30, P<0.01). Time of the first labor was (395.84±165.24) min in the pelvic motion group and (574.35±152.23) min in the walking group, the difference was statistically significant ( t value was 6.32, P<0.01). The second stage of labor was (25.98±9.88) min in the pelvic motion group and (33.62±13.94) min in the walking group, the difference was statistically significant ( t value was 3.57, P<0.01). Conclusions:Pelvic motion in middle and late pregnancy can affect labor force, birth canal, fetus and other delivery factors, reduce movement pain and shorten the time of labor.

Objective To evaluate the efficacy and safety of Qingpeng ointment for the treatment of localized eczema in children.Methods A multicenter,randomized,open-labeled,tacrolimus 0.03％ ointment-controlled clinical trial was conducted.A total of 442 children with localized eczema were enrolled into this study,and divided into 2 groups to topically apply Qingpeng ointment (Qingpeng group) and tacrolimus 0.03％ ointment (tacrolimus group) respectively twice a day for 2 weeks.The children were followed up before the treatment and 1,2 weeks after the treatment,and the efficacy and safety were evaluated at the same time.Results Clinical data from 426 children were included in the efficacy analysis.At 1,2 weeks after the treatment,there were no significant differences in the response rate between the Qingpeng group and tacrolimus group (1 week after the treatment:78.92％ vs.81.77％,x2 =0.545,P =0.460;2 weeks after the treatment:98.65％ vs.97.54％,x2 =0.721,P =0.396).However,the pruritus scores at 1,2 weeks after the treatment were both significantly lower in the Qingpeng group than in the tacrolimus group (1 week:F =14.001,P =0.000;2 weeks:F =11.252,P =0.001).At 1 week after the treatment,the incidence rate of adverse reactions was significantly lower in the Qingpeng group than in the tacrolimus group (P ＜ 0.05).Mild itching,burning sensation and other local irritant sensations were the most common adverse reactions.Conclusion Qingpeng ointment is safe and effective for the treatment of localized eczema in children with good tolerability.

Objective To explore the security and its influencing factors on benign airway stenosis treated with interventional of high pressure balloon expansion catheter.Methods Clinial data of 39 cases of inpatients suffered from benign airway stenosis were chosen.17 cases were male,and 22 cases were female.The ages of them ranged from 15 to 83 years old.According to the clinical symptoms,HRCT 3D reconstruction,and the results of bron-choscope,all patients were treated with balloon expansion catheter at different criterions.The balloon catheter with size that slightly smaller than the targeted normal bronchial tube was chosen,expansion for average 1 -4 times,single balloon expansion time ranged from 0.5 to 4 min,the pressures were kept at 3 -6 atmosphere,and the highest pres-sure did not exceed 8 atmospheric pressure.The efficacy and complications were retrospectively analyzed.Results 19 cases were completely effective,14 cases were basically effective,6 cases were completely ineffective,and the total effective rate was 84.6% (33 /39 ),the incidence of complications was 35.8% (14 /39 ),moreover,no deaths occurred.Conclusion High pressure balloon catheter expansion is one of commonly used technology in breathing interventional treatment;it has the characteristics of easy operation,and immediate curative effect,and so on.But if the improper operation,incorrect selection of the case,or inaccurate evaluation of the stenosis during operation,serious complications and unnecessary iatrogenic injury can be occurred.Therefore,it is worthy of attention and further summarizing by breathing interventional physicians.

Objective To preliminaryly explore the effect and adverse reaction of Marine Injection combined therapy through local spray in benign tracheobronchial stenosis.Methods 19 cases of bronchial tuberculosis were collected in our department.By assessing cough,shortness of breath and other symptoms,chest high -resolution CT (HRCT)of three -dimensional reconstruction,and length were observed by ultrafine bronchial stenosis.According to the pathogeny and types of stenosis,combined multiple intervention were sequentially adopted,and then Marine Injec-tion was sprayed through one -off endoscopic spray tube.All the subjects were divided into the two groups,the higher concentration Marine injection (1 200 mg/mL)group was chosen with the condition of serious inflammation,edema, ulcer and necrosis,obvious local granulation tissue hyperplasia,severe scar stenosis,and the length of stenosis greater than 2 cm or the sectional area of stenosis less than 50% of the normal sectional area,otherwise the low concentration (600 mg/mL)group was chosen.The subjects were reexamined by clinical symptoms,high -resolution CT (HRCT) of three -dimensional reconstruction,and ultrafine bronchoscopy a week after the surgery to dynamically observe the local changes.Depending on the situation,the injection was sprayed once a week,adding up to 2 -4 times.Follow -up visit lasted for 3 months,cough,expectoration or hemoptysis,and dyspnea were observed.Results 11 cases were effective fully,17 cases were effective substantially,7 cases were ineffective,the total effective rate was 80% (28 /35).The overall complication rate was 42.8% (15 /35),no deaths occurred.No complications related to local spra-ying of Marine were seen.Conclusion Local spray of Marine Injection may have preferable effect that inhibits scar formationand prevention airway restenosis.It is worth further study with a high security,precise clinic effect,easy oper-ation and etc.
