Prevalence of insomnia and anxiety among healthcare workers during the COVID-19 pandemic in Jilin Province

The outbreak of the 2019 novel coronavirus disease (COVID-19) has impacted the mental health of healthcare providers at the frontline. Therefore, we conducted this study to estimate the prevalence rate of anxiety and insomnia and identify associated risk factors among healthcare workers in Jilin, China, during the period from January 25 to February 25, 2020. Zung's Self-Reported Anxiety Scale (SAS) and the Insomnia Severity Index (ISI) scale were used to diagnose anxiety and insomnia, respectively. Associated risk factors were identified through a multivariate logistic regression model. A total of 300 healthcare workers were invited and 236 completed the study. Of them, 234 (99.15%) were medical workers, 197 (83.47%) were working at frontline departments, and 159 (67.37%) were fighting against COVID-19. Fifty-seven respondents (24.15%) had anxiety (SAS index score ≥45) and 94 (39.83%) had insomnia (ISI score ≥8). Based on the multivariate analysis, contact with people from Hubei province during work (no vs not clear) [OR=0.25, 95%CI: 0.10-0.61] and personal protective equipment (PPE) (not in place vs in place) [OR=6.22, 95%CI: 2.23-17.40] were significantly correlated with anxiety. PPE (not in place vs in place) was the only significant risk factor of insomnia [OR=10.56, 95%CI: 4.00-27.87]. The prevalence of anxiety and insomnia was high in our study, reflecting the psychological impact of COVID-19 on healthcare workers. The unavailability of PPE in place was a significant risk factor of both anxiety and insomnia.

Effects of isotonic muscle exercise on body shape and neck-shoulder muscle activity of college students / 中国学校卫生

Objective@#The purpose of this study was to investigate effects two kinds of isotonic muscle contraction training on muscle body shape and neck-shoulder muscle activity among college students with physical inactivity and poor body posture, to provide appropriate exercise options for these college students.@*Methods@#Thirty subjects with typical sedentary behavior and upper-cross syndrome were randomly divided into no load isotonic training(IT),resistance isotonic training(RIT) and health education control(C) groups. Two training groups were trained for 12 weeks. All subjects were tested their heath-carter anthropometric somatotype,cervical spine angle,range of cervical spine extending and scapula adduction,surface electromyography data of neck and shoulder musle activity were measured before/after training.@*Results@#After training,three factors value in IT, RIT, C groups were[(3.68±1.01)(5.68±1.05)(3.17±0.54)，(2.84±0.84)(5.87±1.45)(1.34±0.10)，(3.82±0.18)(4.83±1.03)(3.30±0.22)] respectively. After training,cervical spine angles were(32.70±9.20)(20.78±2.24)(11.24±3.21)°; extending angles of cervical spine were(3.21±1.82)(2.24±0.60)(1.24±0.01)°; ranges of scapula adduction were(3.44±1.28)(3.08±1.35)(6.08±1.57)cm in IT, RIT, C groups respectively. Three parameters in two training groups significantly increased(F=8.43, 7.29, 8.04, P<0.05). Antagonistic muscle coactivation in neck and shoulder in three groups were(0.11±0.01) and(0.34±0.02)(0.31±0.01) and(0.56±0.03)(0.36±0.11) and(0.69±0.04) respectively,which significantly decreased in two training groups(F=27.39,5.45,P<0.05). There were more obviously changes of neck and shoulder musclebone system in IT group(P<0.05).@*Conclusion@#Musculoskeletal system improved while body fat reduced after resistance isotonic training. No load isotonic training was more superior in adjusting and correctingg upper-crossed syndrome posture than resistance isotonic training. College students with sedentary behavior and upper-cross syndrome can choose no load isotonic training preliminarily for muscle strength and concordance increasing before adding load.

Association of follicle stimulating hormone receptor promoter with ovarian response in IVF-ET patients

Background: Poor ovarian response phenomenon has been observed in some of the in vitro fertilization-embryo transfer patients. Some investigations found that follicle stimulating hormone receptor [FSHR] gene plays a role in the process, but no direct evidence shows the correlation between genotypes of FSHR and ovarian response

Objective: Exploring the molecular mechanism behind the mutation of FSHR promoter association with ovarian granulosa cells and poor ovarian response

Materials and Methods: This cross sectional study was performed using 158 women undergoing the controlled short program ovarian stimulation for IVF treatment. The 263 bp DNA fragments before the follicle stimulating hormone [FSH] receptor 5' initiation site were sequenced in the patients under IVF cycle, 70 of which had poor ovarian response and 88 showed normal ovarian responses

Results: With a mutation rate of 40%, 63 in 158 cases showed a 29[th] site G-A point mutation; among the mutated cases, the mutation rate of the poor ovarian responders was significantly higher than the normal group [60% versus 23.9%; [chi]2=21.450, p<0.001]. Besides, the variability was also obvious in antral follicle count, and ovum pick-ups. The estradiol peak values and the number of mature eggs between the two groups had significant difference. However, there was no obvious variability [t=0.457, p=0.324] in the basic FSH values between the two groups [normal group, 7.2 +/- 2.3 U/L; mutation group, 7.1 +/- 2.0 U/L]

Conclusion: The activity of FSHR promoter is significantly affected by the 29[th] site G-A mutation that will weaken promoter activity and result in poor response to FSH

Oral epidemic diseases of exposure personnel in long-term low dose radiation / 中国医学科学杂志(英文版)

Oral epidemic diseases of exposure personnel in long-term low-dose radiation yet have rarely been studied. Referred to WHO oral health survey method and symptom grading standard, data of 341 exposure persons in long-term low-dose radiation including α particle, β particle, and γ rays, etc., were collected from one camp in China in 2011 with cluster sampling and analyzed? with Foxpro 6.0 and SPSS 16.0 software. The exposure persons worked in low-dose radiation for a long time aged between 23 and 56, whose average age were 27.1 years old.In addition, their lengths of service were from 2 to 34 years (average 7.9 years) and average exposure time was 8 hours a day each year for more than three months. Average annual radiation dose equivalent was from 1.8 to 16.5 mSv (average 7.3 mSv). Total radiation dose equivalent was from 3.8 to 425.0 mSv (average 97.3 mSv).

new effective method in the treatment of severe ovarian hyperstimulation syndrome

Ovarian hyperstimulation syndrome [OHSS] is a recognized complication of ovulation induction, occurring in 1-10% of IVF and embryo transfer cycles. While mild OHSS is of no clinical relevance, severe OHSS is a life threatening complication. However, the efficacy of prevalent treatments appeared to be limited. We developed a continuous auto transfusion system with an ultra filtration instrument for reinfusion the protein of concentrated ascites for the treatment of severe OHSS. To study the efficacy and safety of using a continuous auto transfusion system for the treatment of severe OHSS. 69 patients with severe OHSS who were treated with controlled ovarian hyperstimulation due to infertility from February 2002 to August 2010 in our reproductive center were divided into two groups. One group treated with continuous auto transfusion system with an ultra filtration instrument which infused the protein of concentrated ascites, called ultrafiltration group, another group were treated with simple-albumin supplement, called albumin group. Several examinational results and adverse effect were compared between the two groups. The volume of urine output after 72h in ultra filtration group was more than that in albumin group, the waist circumference and body weight in ultra filtration group were lower than those in albumin group after 72h. The serum creatinine levels after 72h in ultra filtration group was still significantly lower than that in albumin group [p<0.05]. The ultra filtration group rarely showed adverse effect compared with albumin group. Autotransfusion of protein in concentrated ascites for the treatment of severe ovarian hyperstimulation syndrome was effective and safe

Correlation between Distribution of Helicobacter Pylori in Oral Cavity and Chronic Stomach Conditions / 华中科技大学学报（医学）（英德文版）

In this study,the colonization and distribution of Helicobacter pylori (Hp) in patients with chronic gastric diseases were investigated and the relationship between the periodontal initial treatment and presence of Hp in oral cavity was examined to better understand the connection between Hp infection and chronic diseases.Primers for PCR amplification were designed according to ureC gene and cagA genes of Hp.Specimens were harvested from different sites of 96 patients with chronic gastric diseases and the specimens of dental plaques,gargles and dorsal mucosa were tested for Hp.The 96 patients were treated by bismuth triple therapy and among them,52 subjects were additionally given periodontal initial therapy.The eradication rate of gastric Hp and oral Hp detection rate were determined 4 weeks and 1 year after the treatment.The results showed that the detection rates of oral specimens were in the order of dental plaques (82.3％),gargles (51.1％) and scrapings of dorsal mucosa of tongue (37.5％).One year after bismuth triple therapy or the triple therapy in com bination with periodontal initial treatment,the eradication rate of gastric Hp was significantly higher in the combination treatment group than in group treated by the triple therapy alone (62.8％ vs.32.4％,P＜0.05).Moreover,the Hp detection rate was significantly lower in the combination group than in the group treated only with the triple therapy.We are led to conclude that Hp is present at various parts of oral cavity,oral Hp might be an important source of gastric Hp and the triple therapy plus periodontal initial treatment can enhance the long-term eradication rate of gastric Hp in patient with both chronic gastric diseases and chronic periodontitis.
