Objective To analyze the pathogenic bacteria and drug resistance of peritoneal dialysis-associated peritonitis(PDAP),and provide a clinical reference for the rational use of antibiotics.Methods The demographic data of PDAP patients admitted to the peritoneal dialysis(PD)Center of the First Affiliated Hospital of Soochow University from July 1,2015 to December 30,2021 were collected,and the pathogens,drug resistance and prognosis were retrospectively analyzed.Results A total of 150 episodes of PDAP occurred in 92 patients.The positive rate of PD fluid culture was 61.33％,including 65 cases(70.65％)of Gram-positive(G+)bacteria,mainly Staphylococcus and Streptococcus.Gram-negative(G-)bacteria were in 16 cases(17.39％),mainly Escherichia coli and Enterobacter cloacae.There were 11 cases(11.96％)of multiple infections,including 5 cases of combined fungal infection.From 2016 to 2021,the incidence of G+bacteria-related PDAP decreased from 14 to 8 cases.G+strains were resistant to methicillin(35.00％),and were sensitive to linezolid(100.00％),teicoplanin(100.00％)and rifampicin(100.00％).The sensitivity rate to vancomycin was 98.59％.G-strains were sensitive to ceftazidime(86.36％),ceftizoxime(88.89％)and amikacin(100.00％).The MIC of vancomycin against Staphylococcus showed an upward trend in 2019-2021.The overall cure rate of PDAP was 81.33％in patients who responded to antibiotic treatment,and the cure rate of G+bacteria was higher than that of multiple infections(89.23％vs.36.36％,P＜0.01).The outcome of patients with multiple infections,especially those with concurrent fungal infection was poor.Conclusion The incidence of PDAP in the PD center has shown a decreasing trend in recent years.G+bacteria are still the main pathogenic bacteria causing PDAP,and they are highly resistant to methicillin,so vancomycin should be used as empirical therapy.For G-bacteria,cefotaxime and amikacin can be chosen as empirical therapy.There is a drift in the MIC values of vancomycin against Staphylococcus in the study period,so it is necessary to monitor the MIC of vancomycin against Staphylococcus and its changing trend.

BACKGROUND: The clinical features of enthesitis in patients with psoriatic arthritis (PsA) have been reported in some Western countries, but data in China are very limited. This study aimed to describe the characteristics of enthesitis in Chinese patients with PsA and compared them with those in other cohorts. METHODS: Patients with PsA enrolled in the Chinese Registry of Psoriatic Arthritis (CREPAR) (December 2018 to June 2021) were included. Data including demographics, clinical characteristics, disease activity measures, and treatment were collected at enrollment. Enthesitis was assessed by the Spondyloarthritis Research Consortium of Canada (SPARCC), Maastricht ankylosing spondylitis enthesitis score (MASES), and Leeds enthesitis index (LEI) indices. A multivariable logistic model was used to identify factors related to enthesitis. We also compared our results with those of other cohorts. RESULTS: In total, 1074 PsA patients were included, 308 (28.7%) of whom had enthesitis. The average number of enthesitis was 3.3 ± 2.8 (range: 1.0-18.0). More than half of the patients (165, 53.6%) had one or two tender entheseal sites. Patients with enthesitis had an earlier age of onset for both psoriasis and arthritis, reported a higher proportion of PsA duration over 5 years, and had a higher percentage of axial involvement and greater disease activity. Multivariable logistic regression showed that axial involvement (odds ratio [OR] 2.21, 95% confidence interval [CI], 1.59-3.08; P <0.001), psoriasis area and severity index (PASI) (OR: 1.03, 95% CI: 1.01-1.04; P = 0.002), and disease activity score 28-C reactive protein (DAS28-CRP) (OR: 1.25, 95% CI: 1.01-1.55; P = 0.037) were associated with enthesitis. Compared with the results of other studies, Chinese patients with enthesitis had a younger age, lower body mass index (BMI), a higher rate of positive human leukocyte antigen (HLA)-B27, more frequent dactylitis, and a higher proportion of conventional synthetic disease-modifying antirheumatic drugs' (csDMARDs) use. CONCLUSIONS Enthesitis is a common condition among Chinese patients with PsA. It is important to evaluate entheses in both peripheral and axial sites.

Objective To evaluate the clinical effect of immediate implant restoration in lower posterior teeth . Methods 31 XIVE implants were placed in lower posterior teeth of 31 patients.The temporary fixed resin crowns were fabricated immediately and final restorations were finished in 3~4 months.The control group used nonsub-merged implants and were restored with final crowns in 3~4 months.The tracking survey was taken from 12 to 24 months after final restoration .The patient satisfaction , papilla index score ( PIS ) and implant survival rate were eval-uated between the two groups .Results PIS of patients with immediate restoration reached (2.35 ±0.70) in aver-age compared(1.84 ±0.74) in control group.The patient satisfaction reached (91.5 ±7.5) with immediate resto-ration, compared with VAS score in average of(85.8 ±8.1) in control group.All implants in both groups achieved osseointegration and received 100% survival rate .Conclusion With proper technique in surgical and restoration procedure , immediate restoration after implant insertion in posterior madible has similar clinical success compared with delayed restoration .

OBJECTIVETo summarize and analyze the clinicopathological features and surgical management of patients with pathologic complete response (pCR) in the primary tumor after neoadjuvant chemotherapy for rectal cancer, and to explore the rational treatment of this entity.

METHODSClinical data of fifty-two patients with locally advanced mid-low rectal cancer admitted to the Cancer Institute and Hospital, Chinese Academy of Medical Sciences from January 1994 to December 2013 were retrospectively analyzed. They were treated with neoadjuvant chemotherapy and achieved pathological complete response in the primary tumor. The preoperative clinical staging were stage II (cT3~4N0) in 10 cases and stage III (cT3~4N+) in 42 cases. After the neoadjuvant therapy, 10 cases achieved clinical complete response (cCR) (19.2%).

RESULTSRadical surgery was performed in 51 patients. Among them, five patients (9.8%) had pathological lymph node metastasis. One cCR patient underwent transanal local excision. The postoperative complication rate was 21.2%. During a median follow-up of 23.6 months, only one patient developed bone metastasis and another one had enlarged mesenteric and retroperitoneal lymph nodes detected by imaging. All the patients were alive by the last follow-up. The 2-year disease-free survival rate was 96.2% and overall survival rate was 100%.

CONCLUSIONSRadical surgery remains the standard therapy for cCR patients with rectal cancer after neoadjuvant chemotherapy. Local excision and "wait and see" should be recommended with great caution and limited to patients who cannot tolerate or refuse radical surgery with a strong demanding for sphincter saving, or applied in clinical trials.
