ABSTRACT
OBJECTIVE: To investigate the expressions of peripheral blood microRNA-21(miR-21) and transforming growth factor-beta(TNF-beta)/Smad signaling transduction pathway in patients with bronchial asthma complicated with respiratory virus infection. METHODS: Totally 109 patients with asthma complicated with respiratory virus infection(study group) and 104 patients without virus infection(control group) in the Third People's Hospital of Gansu Province between Feb.2019 and Feb.2021 were selected for the cross-sectional study. The basic data of the two groups were collected, and parameters including vital signs, lung function, peripheral blood miR-21 and TGF-beta/Smad signaling pathway proteins were measured. According to the guidelines, the patients of the two groups were divided into acute exacerbation phase and stable phase. The examination results of each group were compared and the levels of peripheral blood miR-21 and TGF-beta/Smad signaling pathway proteins expression of patients with asthma complicated with respiratory virus infection were analyzed. RESULTS: In study group, the proportion of respiratory virus infection among 109 patients was 33.94% for influenza virus, 23.85% for human rhinovirus, 19.27% for respiratory syncytial virus, 10.09% for parainfluenza virus, 6.42% for adenovirus, 4.59% for human coronavirus and 1.83% for human metapneumovirus respectively. The proportion of patients with acute exacerbation phase in the study group was higher than that in the control group, and the levels of peripheral blood miR-21, TGF-beta1, Smad7, pSmad2 and pSmad3 were higher than those in control group(P<0.05). The levels of miR-21, TGF-beta1, Smad2, Smad3, Smad7, pSmad2 and pSmad3 in peripheral blood of patients with acute exacerbation phase of asthma were higher than those of patients with stable phase of asthma(P<0.05). There were no statistical differences in peripheral blood miR-21, TGF-beta1, Smad2, Smad3, Smad7, pSmad2 and pSmad3 levels in asthma patients with different virus infections. CONCLUSION: Early respiratory virus infections might lead to increased expression of peripheral blood miR-21 and increased activation of TGF-beta/Smad signaling pathway in patients with asthma, which played an important role in acute attack of asthma.

ABSTRACT
Objective To investigate the dynamic changes of severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) specific antibody IgG positive rate in coronavirus disease 2019 (COVID-19) survivors in China. Methods the relevant literatures about the positive rate of SARS-COV-2 specific antibody IgG in COVID-19 survivors in China were retrieved from PubMed, Embase, CNKI, Wanfang database and VIP database from December 2019 to February 24, 2022. The quality of the documents were assessed according the revised AHRQ (Agency for Healthcare Research and Quality) statement. Freeman-tukey double arsinusoidal conversion method was used to calculate the positive rate, and StataSE15.0 software was used for statistical analysis. Subgroup analysis was performed according to detection method and fragment, and publication bias was examined by Egger method. Results A total of 12 articles were included, IgG was detected from the first month to the twelfth month after SARS-COV-2 infection, and the total sample size ranged from 74 to 2 907 cases per month. The positive rate was the highest in the second month and the third month, 96.35% (95% CI: 93.98%-98.14%) and 97.23% (95% CI: 94.47%-99.05%) respectively. The positive rate decreased gradually with time, and reached 73.63% (95% CI: 50.31%-91.45%) in the twelfth month. The results of subgroup analysis showed that the heterogeneity between studies with the different detection method and the different detection fragment were significant differences (X2=5.02-39.57, all P < 0.05). Egger method test published bias, and the difference was not statistically significant (t=1.85, P=0.101). Conclusion Most people, one year after infection with SARSCOV- 2, could still detect SARS-COV-2 specific antibody IgG.
ABSTRACT
Objective: To describe the epidemiological characteristics of COVID-19 patients in Shaanxi Province from December 2021 to January 2022. Methods: All COVID-19 patients' information was obtained from the Health Committee of Shaanxi Province. SPSS 26.0 and Stata MP 16.0 were used to analyze the distribution of Time, Population and Region. Descriptive statistical method was used to investigate the correlation between age, gender and clinical syndrome types of patients. Results: The duration of this epidemic was 43 days, and 2 080 confirmed cases in total, which distributed in cities of Xi'an (2 053 cases), Xianyang (13 cases), Yan'an (13 cases) and Weinan (1 cases). The mean age of the patients was 35.91+or-17.72 years old, the number of male patients was higher than that of female, and 93.7% of the patients had mild symptoms. The age and gender of the patients were statistically correlated with the symptom type (P < 0.001). Conclusion: Preventing the imported and the spread of domestic cases are currently the main measures to prevent COVID-19 in China. People should abide by the requirements and duties of epidemic prevention and control. Health management and strict quarantine should apply for keynote areas and populations. Meanwhile, the discovery of asymptomatic patients is important to prevent the potential epidemic.
ABSTRACT
Objective: To analyze the epidemiological characteristics of an epidemic of coronavirus disease 2019 (COVID-19) caused by occupational exposure in Xining, Qinghai province, from October 17 to November 2, 2021 and provide evidence for the prevention and control of COVID-19 epidemic. Methods: In accordance with the requirements of the COVID-19 prevention and control protocol (eighth edition), epidemiological survey and field response were conducted and throat swabs were collected from the confirmed cases and close contacts. Real time-PCR(RT-PCR) was used to detect severe acute respiratory syndrome coronavirus (SARS-CoV-2) nucleic acid. Gene sequencing was performed for the throat swabs of partial confirmed cases by high throughput sequencing. Results: A total of 11 COVID-19 cases were reported in this epidemic, including 3 cases in a family and 8 cases in medical staff. Nine cases were women, 2 cases were men. The cases in epidemic had 3 generations. The average incubation period was 3.18 day. The infection was mainly occurred in working place. The risk factors included sharing telephone, computer and other office equipment. The initial symptoms were cough (10 cases, 90.97%). Unstandardized taking off protective suit in field epidemiological survey and inappropriate design of waterproof boot cover were the main risk factors for the occupational exposure. The SARS-CoV-2 detected belonged to VOC/Delta variant. Conclusion: This epidemic was caused by occupational exposure. It is suggested to strengthen the field supervision and guide of the wearing of protective suits, improve the design of waterproof boot cover and reduce the contacts of field workers with others.
ABSTRACT
Objective: To understand the epidemiology and etiology of a cluster of cases with gastroenteritis in a nursing home in Anning district of Lanzhou, and to provide a scientific evidence for the prevention and control of norovirus diarrhea in community nursing centers. Methods: From January 28 to February 4 2021, an epidemiological investigation was conducted on all diarrhea cases, nursing staff and chefs in a nursing home in Anning district, Lanzhou city. Samples of patients' anal swabs, feces, vomitus were collected for norovirus detection by real-time fluorescent PCR. ORF1/ORF2 junction region of norovirus in some selected positive samples(Ct value 25) was sequenced. MEGA-X software was used to construct a phylogenetic tree for genetic evolution analysis using the neighboring method. Results: The first case was confirmed on January20,2021, and the number of cases peaked during January 25and 29.A total of 58 clinically diagnosed cases were reported,57were older people, with an incidence of(57/360,15.83%). Diarrhea(50/58,86.21%),vomiting(35/58,60.34%),nausea(13/58,22.41%)and abdominal pain(6/58,10.34%)were common symptoms, all cases were mild. Fifty-three asymptomatic cases were detected among chefs, housekeepers and nurses.A total of 163specimens were tested, the positive rate of norovirus GII was 49.08%(80/163). The positive rate of fecal samples collected from nurses, chefs and housekeepers was 48.62%(53/109), and was11.11%(2/18)in environmental surface swabs. The possibility of other pathogenic infections such as SARS-CoV-2was ruled out by further tests. Thirteen positive samples were selected for sequencing, and 9were successfully sequenced, they were all recombinant GII.4Sydney_2012 [P16]genotypes, forming an independent cluster, while in a large evolutionary branch with the 2020GII.10 [P16]and 2019GII.2 [P16]virus strains in Lanzhou city, showing a relative close genetic connection. Conclusions: GII .4Sydney_2012[P16]genotype of norovirus is found to be causative pathogen of this outbreak, and close contact is the main reason of the outbreak and persistence of the infection,so asymptomatic infections of norovirus play an important role in the disease spreading. Therefore, public health management in nursing homes and other centralized nursing facilities should be strengthened especially for asymptomatic workers in order to prevent virus transmission.
ABSTRACT
Objective: To investigate the predictive values of fasting blood glucose and triglyceride/high-density lipoprotein cholesterol ratio (TG/HDL-C) in non-diabetic patients with COVID-19. Methods: A total of 39 non-diabetic patients with COVID-19 admitted to the Fourth Hospital of Xi'an from December 2021 to January 2022 were included. And 34 health examination subjects from the Second Affiliated Hospital of Xi'an Jiaotong University were matched as health control according to their propensity score. The clinical characteristics and laboratory test results between groups were compared, and the predictive value of fasting glucose and TG/HDL-C in non-diabetic COVID-19 patients was analyzed by logistic regression and receiver operating curve (ROC). Results: COVID-19 patients were either mild (30 cases) or common type (9 cases) with mild symptoms and good clinical prognosis. The median age was 29.0 (20.0, 49.0) years, 24 (61.5%) were males. Fasting blood glucose (4.30+or-0.47 mmol/L) and HDL-C [1.07 (0.86, 1.30) mmol/L] levels in COVID-19 patients were significantly lower than healthy controls [5.15+or-0.70 mmol/L, 2.24 (1.77, 3.05) mmol/L], the differences were statistically significant (t=6.277, P < 0.001;Z=6.026, P < 0.001). However, low density lipoprotein cholesterol (LDL-C) [2.40 (1.81, 2.91) mmol/L] and TG/HDL-C [0.91 (0.54, 1.52)] in COVID-19 patients were significantly increased compared to healthy controls [1.11 (0.99, 1.30) mmol/L, 0.54 (0.33, 0.90)], and the differences were statistically significant (Z=-6.271, -2.801, all P < 0.005). Logistic regression analysis showed that fasting blood glucose on admission could be an independent protective factor (OR:0.020, 95% CI: 0.003 ~ 0.150) and elevated TG/HDL-C be a risk factor (OR:4.802, 95% CI: 1.249 ~ 18.460) for COVID-19 infection among non-diabetic populations. The ROC curve showed that fasting blood glucose and TG/HDL-C were good at predicting the risk of COVID-19, and the area under the curve (AUC) were 0.871 and 0.708, respectively, and was 0.895 when combined. Conclusion: Decreased fasting blood glucose and elevated TG/HDL-C would be risk factors for COVID-19 infection in the non-diabetic population, and both have good predictive value for the incidence of COVID-19.
ABSTRACT
Objective: To find out the existing problems and provide reference for further improving the quality of report information by analyzing the report cards of COVID-19 and the positive report cards of primary screening reported in Ningxia. Methods All COVID-19 case cards from 2020 to 2021 and initial screening positive cards were derived from the Chinese Information System for Disease Control and Prevention according to final review date. The timeliness of case reporting, timeliness of case review, completeness and accuracy of the case cards were analyzed. Results In Ningxia, the first case of COVID-19 was reported on January 20, 2020, and as of December 31, 2021, 122 confirmed cases and 4 symptomatic infected cases were reported. In 2021, the timely reporting rate of COVID-19 was 98.00%, which increased by 8.24% compared with 2020 (90.54%). Compared with 2020, the average time limit for diagnosis to reporting of COVID-19 in 2021 was shortened by 83.12%;in 2021, the timely review rate of COVID-19 was 100.00%, which increased by 13.84% compared with 2020 (87.84%). Compared with 2020, the time from reporting to final review was shortened by 98.91%. In 2021, the timely rate of positive reports in COVID-19 in Ningxia was 90.00%, among which the timely rate of reports by county (district) nucleic acid detection institutions was the highest (92.31%), followed by municipal (91.67%) and autonomous region (81.82%). Conclusions At the beginning of the epidemic in 2020, the timeliness of COVID-19 in Ningxia was poor, and through the implementation of measures such as technical training, supervision and inspection to continuously optimize the staffing of medical institutions and disease control institutions, the timeliness of reporting COVID-19 in Ningxia in 2021 was substantially improved, but there were still some weak links. In the future work, technical guidance and training should be carried out for weak links, and efforts should be made to improve the quality of reports.
ABSTRACT
OBJECTIVE: To investigate and analyze multiple detection of 13 kinds of viruses in 500 children with acute respiratory tract infection in Hami of Xinjiang. METHODS: A total of 500 children with acute respiratory tract infection treated in the hospital between Jan 2018 and Jan 2021 were enrolled. Thirteen kinds of respiratory infection viruses including human respiratory syncytial virus(RSV), human rhinovirus(hRV), respiratory adenovirus(AdV), influenza A and B viruses(Inf A, Inf B), parainfluenza virus(PIV 1/2/3), human enterovirus(hEV), human metapneumovirus(hMPV), human coronavirus(hCoV 229E/OC43) and human Boca virus(hBoV) were detected by multiple reverse transcription polymerase chain reaction(RT-PCR) amplification and capillary electrophoresis. And the results were compared with those by direct sequencing method. RESULTS: Of the 500 samples, 379 samples were positive(75.80%), and the top three detection rates were RSV(19.40%), hRV(16.00%) and Inf B(12.60%). The differences in positive rates of the respiratory virus among <1 year group, 1-3 years group and >3 years group were significant(84.97%, 77.47%, 65.45%)(P<0.05). The detection rate of RSV was the highest in <1 year group, and the detection rates of Inf A and Inf B were the highest in >3 years group. The differences in positive rates of respiratory viruses among the spring group, summer group, autumn group and winter group were significant(74.05%, 63.73%, 77.24%, 84.03%)(P<0.05). The detection rates of RSV, PIV 3, and hMPV were the highest in the winter group, and detection rate of AdV was the highest in spring group. CONCLUSION: RSV is the main infection virus in children with acute respiratory infection in Hami of Xinjiang. The distribution of respiratory viruses is related to age and onset season in children.
ABSTRACT
Objective: To determine the epidemiological characteristics of COVID-19 in Shaanxi Province. Methods: Epidemiological analysis was conducted on the confirmed cases of COVID-19 (n=245) from January 23rd, 2020 through February 21st, 2020 based on the official data announced by Shaanxi Province. The effects of local population migration, prevention and control measures on the epidemic were explored. Results: As of February 21st, 2020, a total of 245 COVID-19 cases had been notified in Shaanxi Province, with a cumulative incidence rate of 0.63 per 100 000, of which imported cases accounted for 47.34%. The high incidence was observed between January 31st and February 5th. Xi'an had the largest number of COVID-19 cases, followed by Ankang, Hanzhong and Xianyang, totally accounting for 81.20% of the cases in the province. In terms of social factors, daily morbidity was positively correlated with Baidu migration scale index 14 days before. On January 25th, the provincial health emergency response was launched, and on January 31st, it was further upgraded for quarantine. On February 20th, the provincial prevention and control system was implemented by classified areas. There were no emerging local cases after February 21st and no confirmed cases for 28th consecutive days as of March 19th. Local cases and close contacts were cleared to zero on March 27th. Conclusion: The COVID-19 epidemic in Shaanxi Province is mainly concentrated in Guanzhong area and southern Shaanxi, with a widespread pattern in all cities. The prevention and control measures have effectively contained the epidemic, with a declining incidence. However, quarantine of suspected cases and close contacts remains crucial for routine prevention and control strategy.
ABSTRACT
To explore characteristics of patients with pneumonia infected by 2019 Novel Coronavirus (COVID-19) in 2019 outside Hubei Province, China. 40 patients with pneumonia infected by COVID-19 which were confirmed by COVID-19 nucleic acid test were included. Procalcitonin (PCT), serum amyloid A (SAA), C-reactive protein (CRP) and computed tomography (CT) manifestations were analyzed. 40% of patients had clear contact history with Wuhan or other areas of Hubei Province. 60% of patients were clustered diseases and 40% were imported cases. 75% of patients had initial fever, 7.5% had cough, 5% had sore throat at first. 45% had decreased lymphocyte count, 72.5% and 55% patients had increased levels of SAA and CRP. 72.5% of the patients showed multiple ground glass lesions in one or two lungs on chest CT. 90% of the patients with pneumonia are of the common type, and a-interferon atomization inhalation combined with Lopinavir/Ritonavir tablets were given to patients during treatment. 62.5% of the patients were treated with antibiotics, and 15% with hormone. All patients improved after treatment, and 14 patients were cured and discharged. Family cluster infection and asymptomatic infection may be the main way of spreading of COVID-19 pneumonia outside Hubei Province in China.
ABSTRACT
Objective: To summarize the clinical characteristics of patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Delta variant infection by comparing with patients with wild strain infection in Gansu Province. Methods: Totally 141 patients diagnosed with Delta variant infection(variant group)and 88 patients with COVID- 19 (wild strain group) in Gansu Province were selected, and their clinical data were retrospectively collected and compared. Results The proportion of patients with hypertension and vaccination was higher in the variant group than in the wild strain group (P < 0.05). Most of the two groups were mild and common types, and there were no statistically significant differences in the other general data (all P > 0.05). The percentages of fever, fatigue, muscle soreness, chest tightness and shortness of breath in the variant group were lower than those in the wild group, and the proportion of sore throat was higher than that in the wild group (all P < 0.05). The proportions of white blood cells (WBC) < 4.0 x 109/L, platelets (PLT) < 100x109/L, glutamyl transpeptidase (GGT) > 50.0 U/L, lactate dehydrogenase (LDH) > 240.0 U/L, blood urea nitrogen (BUN) > 7.1 mmol/L, and international normalized ratio (INR) >1.13 were all lower in the variant group than in the wild strain group (all P < 0.05);the percentage of aspartate aminotransferase (AST) > 40 U/L was higher than that of the wild strain group (P < 0.05). No significant differences were found in the alanine aminotransferase (ALT), blood creatinine (Cr), creatine kinase (CK), creatine kinase isoenzyme (CK-MB), activated partial thromboplastin time (APTT), prothrombin time (PT), calcitoninogen (PCT), or C-reactive protein (CRP) between these two groups (all P > 0.05). The proportions of abnormal chest CT, bilateral lesions, and three or more lobar lesions were significantly lower in the variant group than in the wild strain group (all P < 0.05). The proportions of treatments with interferon, ribavirin, lopinavir/ritonavir, antibiotics, glucocorticoids, immunoglobulins, hemopexin, Abidor tablets, and oxygen were lower in the variant group than in the wild strain group (all P < 0.05). The proportions of treatments with prone ventilation, anticoagulation, neutralizing antibodies, thymofacine, and hepatoprotective therapy were higher in the variant group than in the wild strain group (all P < 0.05). Thirty-five cases (53.0%) of lymphocytes in the wild strain group did not return to normal levels at discharge, and the differences in the time to recovery of lymphocytes, time to absorption of lung lesions, and time to nucle ic acid conversion between the two groups were not statistically significant (all P > 0.05). The recovery time of oxygen saturation (SaO2) in the variant group was shorter than that in the wild strain group, and the time of nucleic acid conversion and hospitalization was longer than that in the wild strain group (all P < 0.05). There were two deaths (2.3%) in the wild strain group and 0 death in the variant group, with no statistically significant difference between the two groups (P > 0.05). Conclusions: Compared with patients with wild strain infection, patients with Delta variant infection are mainly of light and common type with high vaccination coverage, smaller lung lesion involvement, shorter SaO2 recovery time, but longer nucleic acid regression time and hospitalization time, and have a good prognosis after oxygen therapy, traditional Chinese medicine, immune boosting, etc. The prognosis is good after conventional treatment.
ABSTRACT
OBJECTIVE: To understand the epidemiological characteristics of confirmed cases of COVID-19 in Xi 'an, Shaanxi Province during cluster outbreak and explore the prevention and control strategies for the epidemic caused by the Delta SARS-CoV-2 variant. METHODS: The confirmed cases of COVID-19 who were treated in Xi'an People's Hospital, a designated hospital, were enrolled in the study, the data of the patients such as baseline data, diagnostic types and initial symptoms were retrospectively reviewed. RESULTS: Among 703 confirmed cases of COVID-19, the gender ratio of male to female was 1.16:1, the age ranged between 10 months and 94 years old, with the median age 33 years old;the patients with mild symptoms(58.46%) and the patients with common symptoms(39.12%) were dominant. 70.13% of the patients were vaccinated with 2 doses of COVID-19 vaccine, 13.51% have not been vaccinated. In terms of the initial symptoms of COVID-19, the patients with cough accounted for 42.96%, the patients with pharyngeal symptoms accounted for 29.87%, and the patients with fever accounted for 25.60%. Totally 129 patients did not have obvious symptoms during the initial stage. There was significant difference in the influence of age and vaccination on severity of disease(P<0.05). The patients aged no less than 60 years old were the high-risk population for the severe(57.14%) and critically severe(66.67%) symptoms;the morbidity rates of severe symptoms(50.00%) and critically severe symptoms(66.67%) were high among the patients without vaccination. CONCLUSION: The local cluster outbreak caused by Delta SARS-CoV-2 variant in Xi 'an, Shaanxi province are characterized by strong transmission power and fast transmission. It is necessary to focus on the prevention and control among the populations of infants and old people, enhance the epidemiological surgery, precisely trace and isolate close contacts, identify and take interventions to illness condition in early stage. In daily prevention and control, fever, as a typical symptom, should be monitored, and it is necessary to boost the comprehensiveness and sensitivity of symptom monitoring. Universal vaccination remains one of the effective measures for protection of vulnerable populations.

OBJECTIVE: To explore the prevalence of carbapenem-resistant gram-negative bacilli(CRO) infection and the economic burden in a tertiary general hospital of Qinghai province. METHODS: The clinical data, length of hospital stay and costs of hospitalization were retrospectively collected from the patients with Klebsiella pneumoniae, Acinetobacter baumannii and Pseudomonas aeruginosa hospital-acquired infection who were hospitalized in Qinghai Provincial Hospital from Jan 2017 to Dec 2017. The patients were divided into the drug-resistant group and the non drug-resistant group according to the result of drug susceptibility testing. The length of hospital stay and hospitalization cost were compared between the two groups of patients. RESULTS: A total of 521 patients were involved in the study, 120 of who had CRO infection(the drug-resistant group), and 40 had carbapenem-sensitive organisms infection(the non drug-resistant group). The median length of hospital stay of the drug-resistant group was 19 days, the median total hospitalization cost was 31 292 yuan;the median length of hospital stay of the non drug-resistant group was 15 days, the median total hospitalization cost was 22 610 yuan, and there were significant differences between the two groups(P<0.05). Stratified analysis showed that the median length of hospital stay of the patients with carbapenem-resistant K.pneumoniae infection was 17 days, the medial total hospitalization cost 25 227 yuan, the length of hospital stay of the non drug-resistant group was 14 day, the median total hospitalization cost 20 326 yuan;the median lengths of hospital stay of the patients with respiratory tract infection and the patients with bloodstream infection were respectively 19 days and 30 days in the drug-resistant group, the median total hospitalization costs were respectively 30 315 yuan and 30 050 yuan;the median lengths of hospital stay of the patients with respiratory tract infection and the patients with bloodstream infection were respectively 15 days and 13 days in the non drug-resistant group, the median total hospitalization costs were respectively 21 562 yuan and 24 853 yuan, and there were significant differences(P<0.05). CONCLUSION: The hospital-acquired CRO infection may lead to the increase of length of hospital stay and hospitalization cost of the hospitalized patients as well as the economic burden. It is necessary to take effective measures to reduce the incidence of hospital-acquired CRO infection.
ABSTRACT
OBJECTIVE: To retrospectively investigate the association between the non-plan secondary surgery and the nosocomial infection so as to provide objective basis for prevention and control of nosocomial infection in the non-plan secondary surgery patients. METHODS: The medical records of all the patients who received non-plan secondary surgery in a three-A tertiary hospital of Xi'an from Jan 2018 to Dec 2019 were retrospectively investigated. The baseline data, clinical features and status of infection of the non-plan secondary surgery patients were retrospectively reviewed and analyzed by full-time staff of disease prevention and control department. RESULTS A total of 111948 patients underwent surgeries in the whole hospital from Jan 2018 to Dec 2019, 194 of whom underwent the non-plan secondary surgery, accounting for 0.17%. Postoperative hemorrhage was the leading cause of the non-plan secondary surgery, followed by incision infection(57.22%), incision dehiscence(11.34%) and poor healing(8.76%). Among the 194 patients undergoing non-plan secondary surgery, 57 had nosocomial infection, respiratory system, surgical site and blood system were the infection sites, there was 1 case who had nosocomial infection for the first time before the surgery, 24 cases who had nosocomial infection for the first time after the surgery and 32 cases who had nosocomial infection after the secondary surgery. Among the 24 patients who had nosocomial infection for the first time after surgery, 70.83% were male patients, 75.00% had clean-contaminated incision, 66.67% were with the operation duration no less than 3 hours, 75.00% were treated with preoperative antibiotic prophylaxis, and 91.67% were tumor patients. Among the 32 patients who had nosocomial infection after the secondary surgery, 75.00% were male patients, 53.13% were no less than 60 years old, 78.13% were with the operation duration no less than 3 hours, and 68.75% were tumor patients. CONCLUSION: The non-plan secondary surgery and the nosocomial infection are mutually causal, the postoperative surgical site infection for the first time may lead to the secondary surgery, and the secondary surgery may result in the increase of incidence of nosocomial infection.
