ABSTRACT
ObjectiveTo discuss the characteristics of psychological assistance hotline calls and operators' coping strategies of before and after the COVID-19 outbreak， in order to further improve the assistance ability of the psychological crisis hotline. MethodsA retrospective study was conducted on the demographics characteristics， call problems， coping strategies， and call time trends recorded by Changchun psychological assistance hotline information registration platform before the epidemic in Changchun City （January 20， 2019-April 20， 2019） and during the epidemic period （January 20， 2020-April 20， 2020）. ResultsThe differences between gender， age， marital status， location， and occupation type before and during the epidemic were statistically significant （χ2=11.205， 234.240， 152.083， 265.458， 353.385， P<0.01）. The number of different help calls had a statistically significant difference before and during the epidemic （χ2=185.088，P<0.01）. The difference in the number of operators’ different coping strategies before and during the epidemic was statistically significant （χ2=226.810， P<0.01）. Before the epidemic， the main peak of incoming calls was concentrated at 16∶00 to 17∶00， and the secondary peak was concentrated at 22∶00 to 23∶00. During the epidemic， the main peak of incoming calls was also concentrated at 16∶00 to 17∶00， while the secondary peak was concentrated at 10∶00 to 11∶00. ConclusionDuring the COVID-19 epidemic， the number of calls to the psychological assistance hotline was higher than that before the outbreak. The main peak time for calls was the same， and the secondary peak was adjusted from 22∶00 to 23∶00 to 10∶00 to 11∶00. During the epidemic， the number of calls from male， 30 to 39 years old， married， local and staff in Changchun was the most， psychological problems counseling and operator referral strategy were the most before and after the epidemic.
ABSTRACT
Objective To investigate the relationship between HBV -DNA load and serum markers in chronic hepatitis B( CHB) patients in Hohhot,Inner Mongolia,and to explore the mutation of HBV genotype and nucleoside analogue.Methods From January 2015 to December 2017,one hundred and ninety-three CHB patients hospitalized in the People＇s Hospital of Inner Mongolia were selected randomly.The clinical diagnostic criteria for all admitted patients were based on the " Guidelines for the Prevention and Treatment of Chronic Hepatitis B" jointly formulated by the Infectious Diseases Society of 2010. The HBV -DNA load of HBV was detected by real -time quantitative PCR,and the correlation between HBV -DNA load and serum markers was analyzed. Seventy -nine patients were selected from 193 hospitalized patients,PCR-reverse dot blot hybridization was used to analyze HBV genotyping and the drug resistance mutations of different genotypes.Results The differences of HBeAb level and HBV-DNA load between HBeAg positive patients and negative patients were statistically significant(all P<0.001). Of 79 serum specimens of HBV infected people,9 cases(11.4% ) were B genotypes,and 70 cases of C genotype (88.6% ).Of them,25 cases had different loci variation,the rate of variation was 31.6% (25/79),with the unit point rtS213T mutation dominated,accounting for about 24.0% (6/25).Conclusion In Hohhot Inner Mongolia patients with CHB,HBV-DNA load with HBeAg and HBe Ab level are correlated;genotype in patients including B type and C type,which is mainly genotype C;patients with CHB mainly had drug resistance to lamivudine and adefovir dipivoxil, mutations including rtS213T,and hybrid mutation.

ABSTRACT
Objective To realize antimicrobial resistance and carrying status of OXA carbapenemase among imi-penem-resistant Acinetobacter baumannii (IRAB)isolated from patients of Hohhot,so as to provide guidance for the prevention and control of healthcare-associated infection(HAI)caused by multidrug-resistant Acinetobacter bauman-nii .Methods 49 IRAB isolates from 3 tertiary first-class hospitals in Hohhot between January and December 2012 were collected,antimicrobial susceptibility testing was performed by Kirby-Bauer disk diffusion method,four geno-types(blaOXA-51-like ,blaOXA-23-like ,blaOXA-24-like ,blaOXA-58-like )of OXA carbapenemase were detected by polymerase chain reaction (PCR).Results All 49 isolated IRAB strains were found to be highly resistant to antimicrobial agents (81 .63%-100.00%)except to minocycline (8.16%);blaOXA-51-like was identified in 49 strains (100.00%),42 (85.71 %)of which also carried blaOXA-23-like gene ,blaOXA-23-lik and blaOXA-51-like were both found in three hospital, blaOXA-24-like and blaOXA-58-like weren’t found.Conclusion IRAB strains present multidrug resistance,resistant to mi-nocycline is the lowest;blaOXA-23-like is the main drug-resistance mechanism of IRAB in Hohhot.
ABSTRACT
Objective To study risk factors with the occurrence of the mesh exposure after pelvic floor reconstruction.Methods From Mar.2007 to Mar.2011,a retrospective study was made on the clinical data of 353 patients undergoing vaginal mesh pelvic floor reconstruction.The related complications of the mesh were surveyed,and risk factors associated with the mesh's exposure were studied by single factor and multiple factors logistic regression.Results It was found that the exposure rate was 9.6％ (34/353) after 1 year postoperative follow-up.Single factor analysis showed that patients who were not less than 70 years old,patients who were on their menopause stage,the occurrence of not less than three parturition,history of pelvic surgery,diabetes and smoking had a significant correlation (all P ＜ 0.05) with the occurrence of the mesh exposure after pelvic floor reconstruction.Multiple factors logistic regression analysis showed that patients who were not less than 70 years of age (OR =2.389),the occurrence of not less than three parturition (OR =2.688),the history of diabetes (OR =3.545),the history of pelvic surgery (OR =5.385) were the independent risk factors,and the operation experience was the protection factors (OR =0.134).Conclusions Mesh exposure is a common complication after pelvic floor reconstruction.Old age,multiple delivery,history of diabetes and history of pelvic surgery are the risk factors of mesh exposure.Preoperative full assessment and the quality of training contribute to reduce the incidence.
ABSTRACT
Objective To explore the cause and effective management and prevention of septic shock after minimally invasive percutaneous nephrolithotomy (MPCNL) in the elderly.Methods Clinical data of 13 patients with septic shock after MPCNL in our hospital were retrospectively analyzed,and the cause,prevention and treatment of septic shock were investigated.Results The incidence of septic shock in patients undergoing MPCNL was 3.54％ in this study.Single-factor analysis and logistic regression analysis showed that the risk factors for post-MPCNL septic shock were female and the history of diabetes (both P＜0.05).Conclusions Septic shock is a serious complication after MPCNL.Intensive perioperative prevention measures can reduce the incidence of septic shock.Early diagnosis and proper treatment are the keys to successful treatment of septic shock.

Objective:To evaluate the correlation of orbital computed tomography and incretion in patients with thyroid associated ophthalmopathy- Ⅰ. Methods : Seventy-six orbits of 38 patients with thyroid associated ophthalmopathy were evaluated by CT in respect to the density and the size of extraocular muscles, and 100 normal orbits of 50 healthy person were evaluated with the same indices for comparison. Results:There was significant difference in the density and the size of extraocular muscles between the patients and the healthy adults. The maximal size of extraocular muscles were positive correlation with T3,T4in TAO-Ⅰ, and negative correlation with TSH. Conclusion:The manifestation of orbital CT may be a good index in the following survey of thyroid associated ophthalmopathy-Ⅰ.
