Objective:To study the clinical characteristics and differences between clinical subtypes of neonates with SARS-CoV-2 infection.Methods:From December 11, 2022 to January 10, 2023, neonates with SARS-CoV-2 infection admitted to our hospital were retrospectively studied. The neonates were assigned into two groups according to the clinical classification: the mild group (including asymptomatic, mild and moderate disease) and the severe group (including severe and critical disease). The clinical characteristics were summarized and compared between the groups.Results:Among 162 confirmed cases, 91 (56.2%) were male, 27 (16.7%) were preterm infants and 26 (16.0%) were low birth weight infants (LBWIs). The average age of onset was 15(8,21)d with 125 cases (77.2%) had onset after 7 d of birth. The main clinical manifestations included fever (79.0%), cough (59.3%) and nasal congestion (42.6%). 70 cases (43.2%) had abnormal complete blood count (CBC) with neutropenia most common. 136 cases (84.0%) were in the mild group and 26 in the severe group. The severe group showed higher proportion of male, preterm and LBWIs than the mild group ( P<0.05). The most common clinical manifestation was fever in the mild group and cyanosis in the severe group. Compared with the mild group, the severe group had higher incidence of poor response and longer duration of fever ( P<0.05). No significant difference existed in CBC between the two groups ( P>0.05). 127 neonates received chest X-ray and 77(60.6%) showed pneumonia. 157 neonates were discharged with improvement or full-recovery. The length of hospital stay was 5(3,6)d. 5 patients were discharged refusing further treatment. Conclusions:Most SARS-CoV-2 infections in neonates are mild and moderate types with mild symptoms and fever. A few are severe or critical types with cyanosis the most common symptom. Neonates with poor responses and prolonged fever need to be alerted to the possibility of severe disease, especially for male, preterm and LBWIs. Most neonates have a favorable prognosis.

Objective To explore the ART willingness and influencing factors of male HIV/AIDS patients in a special prison area in Shanghai. Methods The information was collected from face-to-face questionnaire survey of HIV/AIDS patients conducted from July 1, 2019, to December 31, 2019. Data was analyzed by univariate and multivariate analysis. The influence of social demographic characteristics, basic situation of detention, AIDS epidemiology, knowledge of AIDS ART, and family awareness on the willingness of anti-virus treatment was investigated. Results A total of 121 HIV / AIDS patients were investigated in this study. The results of multivariate analysis showed that HIV / AIDS patients who were less likely to receive ART included patients with multiple custody, patients with ART knowledge score less than 8, patients whose family members were unaware of their HIV infection, patients thought that they met the treatment standard but had no symptoms and did not need to take medicine, and patients thought that they could discontinue taking medicine at will. Conclusion A variety of factors have an impact on ART willingness of HIV/AIDS patients in custody. It is suggested that HIV / AIDS patients should be provided with more targeted ART knowledge training and social care and family support as far as possible.

Objective:To investigate the significance of MLH1 protein expression and MLH1 gene methylation rate between metastatic solid pseudopapillary tumor of pancreas (SPT) and non-metastatic SPT, and to explore the correlation between MLH1 gene methylation and SPT metastasis.Methods:Twelve metastatic SPT patients admitted to Peking University People's Hospital, Rizhao Central Hospital and Chaoyang Central Hospital of Liaoning Province from January 2009 to May 2022 were studied retrospectively, including 3 males and 9 females, with a median age of 47 years old, ranging from 21 to 73 years old. Thirty non-metastatic SPT patients with clear diagnosis, clear medical history and complete follow-up data from pathological database of Peking University People's Hospital from January 2009 to May 2017 were selected as the control group, including 12 males and 18 females, with a median age of 42 years old, ranging from 34 to 69 years old. Clinical data such as gender, age and pathological data were collected. Immunohistochemical expression of MLH1 protein and methylation of MLH1 gene were detected by pathological paraffins.Results:There was no significant difference in general data between the two groups (all P>0.05). Among the 12 metastatic SPT patients, 4 cases metastasized to liver, 2 to spleen, 2 to lung, 2 to lymph nodes, 1 to mediastinum, and 1 to sacrum. Compared with the non-metastatic tissue, the MLH1 protein deletion in metastatic pancreatic lesions (metastatic SPT-P) and metastatic lesions (metastatic SPT-M) were increased [both 33.3%(4/12)], and the difference was statistically significant (both Chi square=5.00, both P=0.041). Compared with 0 (0/30) MLH1 gene methylation rate in non-metastatic SPT tissues, the methylation rate of MLH1 gene in metastatic SPT-M and metastatic SPT-P tissues [both 30% (3/10)] were higher, with statistical significance (both Chi square=0.96, both P=0.032). Conclusion:Compared with non-metastatic SPT, the loss rate of MLH1 protein expression and MLH1 gene methylation are increased in metastatic SPT. MLH1 methylation may occur before metastasis, which can be used as a predictor of SPT metastasis.

Objective:To explore the effect of previous intestinal resection on anastomotic fistula within 30 days after surgery in Crohn′s disease.Methods:The clinical data from 92 Crohn′s disease patients who underwent intestinal resection and anastomosis at the Department of General Surgery in Shanghai Ninth People′s Hospital, Shanghai Jiaotong University School of Medicine from Jan 2016 to Sep 2019. Patients were divided into no previous intestinal resection group ( n=45) and previous intestinal resection group ( n=47). The relationship between previous intestinal resection and postoperative anastomotic leak in Crohn′s disease patients with intestinal resection and anastomosis was analyzed. Results:A total of 11 cases (12% leak rate) underwent postoperative anastomotic leak. There were 2 leaks in patients with no previous history of intestinal resection, while 9 leaks in patients with previous bowel resection (χ 2 =4.722, P=0.03). The OR of the postoperative anastomotic leak in Crohn′s disease patients with previous intestinal resection compared with no previous intestinal resection group was 5.092 (95% CI: 1.035-25.048). Patients with 1 previous resection (24 cases) had a leak rate of 13%, whereas patients with >1 previous resection episodes (23 cases) had a leak rate of 26%. The number of previous resection episodes correlated with an increasing risk for clinical anastomotic leak (correlation coefficien r=0.995). Conclusions:Previous intestinal resection is an independent risk factor for ensuing postoperative anastomotic leak in Crohn′s disease patients with intestinal resection and anastomosis.

Objective:To investigate the feasibility of near-infrared fluorescence imaging (NIRFI) to assist in determining the resection range of radiation intestinal injury (RII).Methods:A descriptive cohort study was conducted. Clinical data of 10 RII patients who presented intestinal obstruction and received operation with more than 100 cm of small intestine had been resected atGeneral Department of Jinling Hospital from October 2014 to January 2015 were retrospectively analyzed. The Novadaq SPY Intra-operative Imaging System was used in capturing and viewing fluorescent images. Firstly, the dense adhesion was mobilized and the obstructive intestine was fully freed under laparoscopy, then entering into abdomen from the corresponding incision. The surgeon determined the resection range according to the color of the intestinal serous layer of the diseased intestinal wall, the thickness of the intestinal wall, and the degree of swelling of the mesentery. Afterwards, intra-operative NIRFI was performed by intravenous injection of 2 ml indocyanine green (ICG) and the imaging results of the diseased intestinal arteriovenous phase were observed and recorded. The evaluation criteria for the final resection range were mainly based on the changes in mesenteric arterial phase imaging. In RII lesions, mesenteric vessels in mesenteric artery phase were disordered, and the comb-like distribution of normal mesenteric vessels completely disappeared. Only the clouded appearance in the intestinal wall was observed. Imaging results of the diseased intestinal tissue during the development phase and mesenteric vein phase were not significantly different from normal intestinal tissue. Intraoperative and postoperative conditions under NIRFI-assisted positioning, including the resection range, anastomosis site, operation-related complications, hospitalization time and cost were recorded. Data of abdominal contrast-enhanced CT and gastrointestinal angiography during 5 years of follow-up were collected to evaluate whether there was anastomotic stenosis or insufficient resection of diseased bowel.Results:Based on the imaging of mesenteric arterial phase of NIRFI, the median resection length of the small intestine was 185 (120-260) cm. After NIRFI imaging, only local lesion of ileum was excised in 6 patients, and jejunum-ileum anastomosis was performed to preserve ileocecal flap. No serious complications such as anastomotic leakage and anastomotic hemorrhage, or chronic intestinal failure such as short bowel syndrome occurred. The median hospitalization time was 32 (22-51) days, and the median hospitalization cost was 142 000 (90 000-175 000) RMB. The hospitalization time and cost were mainly used for the enteral and parenteral nutrition support treatment during the perioperative period. All the patients had normal oral diet and/or oral enteral nutrient. After 5 years of follow-up, no recurrence was found. Abdominal contrast-enhanced CT and gastrointestinal angiography showed no thickening of the intestinal wall or stenosis of the lumen.Conclusion:Mesenteric arterial phase imagingof NIRFI can help surgeons to determine the site and range of resection of RII lesions.

Objective To evaluate the levels of total serum bilirubin(TSB),amplitude integrated electroencephalogram(aEEG) monitoring and brainstem auditory evoked potential(BAEP) individually and in combination for the early diagnosis of neonatal acute bilirubin encephalopathy by receiver operating charac-teristic( ROC) curve. Methods Clinical data was retrospectively analyzed. A total of 152 infants were diag-nosed with hyperbilirubinemia,including 119 cases of non-bilirubin encephalopathy group and 33 cases of bil-irubin encephalopathy group. The detection results of peak serum bilirubin,aEEG,BAEP combined with the three methods were determined with ROC curve analysis. Results The areas under ROC curve of TSB lev-el,aEEG,BAEP and in combination were 0. 900,0. 738,0. 767,0. 925,respectively,the corresponding sensi-tivity(specificity) in the cut-off point were 90. 91%(78. 15%),87. 88%(59. 66%),65. 52%(87. 91%), 93. 10%(82. 42%),respectively. It showed that the area under ROC curve of the maximum,the comprehen-sive assessment in diagnostic sensitivity and specificity of the combination of three methods were better than any single detection method by ROC curve. Conclusion The methods of TSB level,aEEG and BAEP play an important role in the diagnosis of neonatal bilirubin encephalopathy,and combination with the three meth-ods can improve the accuracy of diagnosis.

Objective To explore the clinical value of human acellular dermal matrix (HADM) in giant complex abdominal wall reconstruction (GCAWR) after open abdomen.Methods The retrospective crosssectional study was conducted.The clinical data of 6 patients with severe trauma who were admitted to the Nanjing General Hospital of Nanjing Military Command of Nanjing University School of Medicine between January 2013 and January 2014 were collected.After open abdomen,fascia of the abdominal wall was fully freed using the component separation,and abdominal wall defects were reconstructed using HADM in the rectus abdominis anterior sheath and peritoneal layers bridge-type suture.Observation indicators:(1) intra-and post-operative situations:operation time,volume of intraoperative blood loss,removal time of postoperative drainage-tube,postoperative complications,duration of hospital stay and hospital expenses;(2) follow-up situations:recurrence of abdominal wall hernia at postoperative year 2.Follow-up using outpatient examination and telephone interview was performed to detect the recurrence of abdominal wall hernia up to April 2016.Measurement data with normal distribution were represented as ~±s.Results (1) Intra-and post-operative situations:6 patients underwent successful surgery.Operation time,volume of intraoperative blood loss and removal time of postoperative drainage-tube were respectively (77±9)minutes,(225±57)mL and (8±3)days.Two patients with postoperative seroma were cured by conservative treatment.One patient with postoperative anastomotic leakage received continuously irrigation and drainage,and leakage was stopped using the biomedical fibrin glue.There was no abdominal bulge of the 6 patients in hospital.Duration of hospital stay and hospital expenses were respectively (10±3) days and (12±7) × 104 yuan.(2) Follow-up situations:6 patients were followed up for 14-28 months,with a median time of 23 months.Two patients had relaxation and bulge of HADM in peritoneal layer at postoperative 2 years,without bulge of HADM in the rectus abdominis anterior sheath layer.There were no occurrence of abdominal wall hernia,chronic pain,paraesthesia,swelling in the local area and other adverse reaction.Conclusion Using of HADM in the rectus abdominis anterior sheath and peritoneal layers bridge-type suture is safe and feasible for GCAWR,with good short-term outcomes.
