The sequencing library was constructed by Ion AmpliSeq Library Kit Plus, and the monkeypox virus genome was sequenced using Ion Torrent GeneStudio S5 sequencer. Monkeypox virus was analyzed for genomic profiling and mutation site analysis using the online analysis tool Nextclade. The genomic sequence of the case virus in this study was compared with some sequences in the GIASID monkeypox virus database and a phylogenetic tree was constructed to analyze the potential origin of the case virus.Results:The Ct values of monkeypox virus genes in the rash swab and oropharyngeal swab samples were 32.13 and 36.91, respectively. The rash swab sample had a reads number match of 99.99% and a genome coverage of 99.45% after whole-genome sequencing of monkeypox virus, and the sequences belonged to the IIb (West African branch) B. 1.3 type. The analysis of nucleotide mutation sites and phylogenetic tree showed that the sequences were in the same branch with four monkeypox virus genome sequences recently submitted by China and Japan in the GISAID monkeypox virus database, and had the closest evolutionary relationship with the sequence EPI_ISL_18059184 (sampled on 2023-07-03) submitted by Yunnan, China, which shared 82 single-nucleotide mutation sites, among which the sequence from Yunnan was only present in all of the shared 82 single-nucleotide mutation sites. The sequence in this study has 2 additional nucleotide mutation sites on top of the shared 82 single nucleotide mutation sites. The sequence submitted by Japan, EPI_ISL_17692269 (sampled on 2023-04-28), is more closely related in evolution, sharing 78 single nucleotide mutation sites, with 7 single nucleotide mutation site differences, and the Japanese sequence shares 78 single nucleotide mutation sites. The Japanese sequence shared 78 mutation sites with one additional nucleotide mutation site (G57786A), while the present sequence had six additional nucleotide mutation sites (G13563A, C21062T, G101241A, C142797T, G152866A, T169721A).Conclusions:The whole genome sequence of monkeypox virus of 197 084 bp was successfully obtained from a sample with low viral load, and the average. We constructed a method for sequencing and analyzing the whole genome of monkeypox virus.

Objective:To analyze the distribution and drug resistance of wound pathogenic microorganisms in outpatients of wound healing center so as to provide a basis for the standardized construction of wound healing centers.Methods:A retrospective case series study was used to analyzed the data of 365 outpatients treated at Ruijin Hospital, Shanghai Jiaotong University School of Medicine from December 2017 to October 2019. There were 220 males and 145 females, aged (58.8±18.9)years (range, 18-98 years). The patients included 92 first-visit patients and 273 re-visit patients. The culture results (positive rate of pathogenic microorganisms, bacterial species, bacterial distribution) and drug sensitivity results of the wound secretions were compared and analyzed.Results:(1) Among 365 samples of wound secretions, 198 patients were positive for pathogenic microorganisms with a positive rate of 54.3%. A total of 107 strains (51.0%) of Gram-positive bacteria were detected, mainly Staphylococcus aureus (70 strains, 33.3%); 95 strains (45.2%) of Gram-negative bacteria were detected, mainly Escherichia coli (20 strains, 9.5%), followed by Pseudomonas aeruginosa (17 strains, 8.1%); 8 strains (3.8%) of fungi were detected. (2) A total of 26 (28.3%) first-visit patients were positive for pathogenic microorganisms, and 172 (63.0%) re-visit patients were positive for pathogenic microorganisms. The rate of positive microorganism detection had significant differences between first-visit and re-visit patients ( P<0.05). (3) A total of 29 strains were detected in first-visit patients, including 16 strains (55.2%) of Gram-positive bacteria, 11 strains (37.9%) of Gram-negative bacteria and 2 strains (6.9%) of fungi. A total of 181 strains were detected in re-visit patients, including 91 strains (50.3%) of Gram-positive bacteria, 84 strains (46.4%) of Gram-negative bacteria and 6 strains (3.3%) of fungi. The microbial distribution was significantly different between first-visit and re-visit patients ( P<0.05). (4) Compared with first-visit patients, the resistance of Staphylococcus aureus isolated from the re-visit patients to spenicillin, oxacillin, ciprofloxacin, tetracycline, clindamycin, moxifloxacin, erythromycin, and levofloxacin were increased variably. No vancomycin-resistant Staphylococcus aureus was detected, indicating that the staphylococcus aureus presented in the wound was highly sensitive to vancomycin. Conclusions:Staphylococcus aureus is the most common microorganism in wound secretions in outpatients of wound healing center. The rate of positive pathogenic microorganisms in wound secretions of re-visit patients is significantly higher than that of first-visit patients, and the distribution of pathogenic microorganisms of first-visited and revisited patients differs significantly. The Staphylococcus aureus detected in re-visit patients has a higher resistance to common antibiotics compared with first-visit patients. It is suggested that timely detection of pathogenic microorganisms in outpatients and effective control and supervision of outpatient infections are important contents that cannot be ignored in the construction of wound healing center.

According to a document issued by the General Office of National Health Commission, "one person, one diagnosis, and one room" is required in the process of outpatient consultation. However, the patient will need to go to another room for dressing change after the doctor checks the wound if sticking to the conventional layout of current wound repair specialist outpatient clinic in hospitals and following the regulation of "separation of diagnosis and treatment". To allow a patient walking back and forth with the exposed wounds to different clinics or going to another clinic for dressing change with the original dressing reapplied to the wound is against the regulation of nosocomial infection control and the principle of sterility. To ensure that the layout of the outpatient clinic in the wound repair outpatient department not only conforms to the principle of "one person, one diagnosis, and one room", but also meets the characteristics of the diagnosis and treatment process of chronic wounds, this paper proposes the layout of "large space and small partition" in the wound repair clinic.

Objective:To explore the application value of flexible endoscopy and rigid endoscopy in the clinical examination of chronic sinus tract wounds with different shapes.Methods:A retrospective observational study was conducted. From January 1 to December 23, 2019, a total of 46 patients with chronic sinus tract wounds, who met the inclusion criteria were admitted to the Wound Healing Center of Ruijin Hospital Affiliated to Shanghai Jiao Tong University School of Medicine, including 23 males and 23 females, aged 18-81 (48±21) years. On admission, computer tomography (CT) imaging and three-dimensional reconstruction were performed to examine the shapes of wound sinus tract and classify the wounds, with the lengths of wound sinus tract by CT imaging examination (hereinafter referred to as reference lengths) recorded. The lengths of wound sinus tract were examined and measured by rigid endoscopy and flexible endoscopy. The wounds with and without obviously curved sinus tract were classified into curve group and linear group respectively, and the deviation rates between the lengths of wound sinus tract measured by flexible endoscopy or rigid endoscopy and the reference lengths (hereinafter referred to as deviation rates of lengths) in each group were calculated. The difference between the deviation rates of lengths examined by flexible endoscopy and rigid endoscopy and the differences between the above two and the deviation rate of reference lengths (0) in each group were compared. Data were statistically analyzed with paired sample t test and Wilcoxon signed rank sum test. Results:CT imaging and three-dimensional reconstruction showed that there were 4 types of wound sinus tract, including tubular (36/46), lamellar (4/46), club-mallet (4/46), and irregular (2/46) shape. Tubular wounds were further divided into type I (23/36), type L (4/36), and type Y (9/36). Wounds with type I tubular, lamellar, and club-mallet sinus tract were classified into linear group (31/46), while those with type Y tubular, type L tubular, and irregular sinus tract were classified into curve group (15/46). In linear group, the deviation rates of lengths examined and measured by rigid endoscopy and flexible endoscopy were 0. In curve group, the deviation rate of lengths examined and measured by flexible endoscopy was 0 (0, 0.58%), which was significantly lower than 41.18% (31.68%, 48.41%) examined and measured by rigid endoscopy, Z=-3.408, P<0.01; the deviation rate of lengths examined and measured by rigid endoscopy (40±19)% was significantly higher than the deviation rate of reference lengths ( t=8.343, P<0.01), while the deviation rate of the lengths examined and measured by flexible endoscopy was similar to the deviation rate of reference lengths ( Z=-1.342, P>0.05). Conclusions:Compared with rigid endoscopy, flexible endoscopy can observe the internal characteristics of chronic sinus tract wounds in a wider range in the clinical examination of this kind of wound, especially for the exploration of curved chronic sinus tract wounds. The promotion of this method will be conducive to the diagnosis and treatment of chronic sinus tract wounds.
