Objective To investigate palmar hyperhidrosis (PH) and the effects on mental health in a military command.Methods 26 392 soldiers were enrolled in this study by stratified-cluster random sampling.Each was required to complete a self-administered questionnaire regarding PH.The soldiers were assessed with symptom checklist-90 (SCL-90) and the factor scores were compared with army norm and civilian norm.Results A total of 25680 subjects fulfilled the questionnaires,and the response rate was 97.3％.The prevalence of PH in the survey sample was 2.66％ and the mild,moderate,and severe PH were 1.49％,0.83％,and 0.34％,respectively.The total mean score of SCL-90 in soldiers with PH (1.72±0.54) was higher than those none PH soldiers (1.65±0.58),civilian norm (1.49±0.41) and military norm (1.63±0.30).Multiple regression analysis showed that age,level of education and severity of PH were important factors for mental health of soldiers with PH (P＜0.05).Conclusion PH is more common in the military,which affect the mental health.The health service departments should pay attention to the treatment and psychological intervention of PH.

In this study ,we analyzed the genetic characterizations and propagation paths of measles viruses prevalent in Ningbo ,China from 2004 to 2013 .Measles viruses were isolated from throat swab specimens from 2004 to 2013 ,and 450 bp fragments of C terminus of nucleoprotein (N) gene were amplified by RT-PCR .Sequence analysis was conducted of all 31 virus strains ,and then compared with other measles virus strains published in GenBank .Results showed that all the 31 measles virus isolates belonged to genotype H1 ,6 strains (one strains in 2004 and 5 ones in 2005) belonged to H1b subtype ,and others be-longed to H1a subtype .Compared the 31 strains to the China 93-4 and China 94-7 ,the homology of 450 bp fragments of C ter-minus of nucleoprotein (N) gene were 97 .1%-100% and 96 .7%-100% ,respectively .The homology of 450 bp fragments of nu-cleotide and nucleotide (amino acids) compared with S191 were 81 .9%-92 .4% and 87 .2%-90 .6% ,respectively .It’s suggested that genotype H1 measles virus circulated in Ningbo from 2004 to 2013 ,and H1a was the predominant epidemic strain ,and H1b strain was existed as well .There are five different transmission chains of H1a subtype caused measles co-circulations in Ning-bo .

Objective To investigate the safety of young recipients undergoing living donor renal transplantation from elderly relative donors through long-term follow-up of the pathological changes. Methods According to the age of donors, 28 young recipients were divided into the observation group (n=14, elderly donors) and control group (n=14, young and middle-aged donors). The 7-year survival after renal transplantation, the serum creatinine (Scr) levels at various postoperative time points were compared between two groups. The chronic pathological injury scores of renal allograft biopsy at time-zero, postoperative 6-month and 7-year were compared between two groups. The expression levels of renal interstitial fibrosis indicators connective tissue growth factor (CTGF), transforming growth factor (TGF)-β, laminin (LN), fibronectin (FN), cell senescence indicators intercellular connexin (Cx)-43 and mammalian target of rapamycin (mTOR) at postoperative 6-month and 7-year were compared between two groups. Results The 7-year survival rates in the observation and control groups were 78.5% and 92.8% with no statistical significance (P > 0.05). In the observation and control groups, the levels of Scr were 190 and 160 μmol/L at the postoperative 7 d, and 170 and 125 μmol/L at postoperative 1 month. At each postoperative time point, the levels of Scr in the observation group were significantly higher than those in the control group (all P > 0.05). The total chronic pathological injury scores of renal transplant biopsy at time-zero in the observation group was significantly higher than that in the control group (P > 0.05), whereas the total chronic pathological injury scores at postoperative 7-year did not significantly differ between two groups (P > 0.05). Within either group, the total chronic pathological injury scores at postoperative 7-year was remarkably higher than those at time-zero and postoperative 6-month (both P < 0.05). The expression levels of CTGF, TGF-β, LN, FN, mTOR, Cx43 of renal transplant tissue at postoperative 7-year did not significantly differ between two groups (all P > 0.05). Conclusions The long-term follow-up outcomes demonstrate that the pathological changes of young recipients undergoing renal transplantation from elderly donors are similar to those from young and middle-aged donors. It is safe and feasible for young recipients to undergo renal transplantation from elderly donors in the pathological perspective.

Objective To explore treatment methods of donor kidney with single calculus in living renal transplantation and their effect.Methods The treatment experience of donor kidneys with unilateral renal calculus in living renal transplantation of 3 cases was summarized,which were diagnosed before operation.The kidney with renal calculus was excised as the donor kidney;ureteroscopic lithotomy was conducted in vitro,and then renal transplantation was performed by routine operation.Results There was no early complication such as delayed graft function and acute rejection in 3 recipients after operation.Three pairs of donors and recipients were followed up for 34,45 and 62 months respectively.The color Doppler ultrasound examination of urinary system after renal transplantation showed that,new renal calculus and urinary tract obstruction did not occur in donor's preserved kidneys and recipient's transplant kidneys.Renal function of all donors and recipients was good.Three donors were followed up until now,and no abnormal urine routine was discovered.One recipient developed IgA nephropathy,which was considered to be recurrent nephropathy and had nothing to do with renal calculus.Conclusions The donor kidney with single calculus in living renal transplantation can be treated effectively by ureteroscopic lithotomy in vitro after donor kidneys are excised.

OBJECTIVETo evaluate the breakthrough varicella infection rate and varicella vaccine effectiveness (VE) among children who received 1-dose varicella vaccine.

METHODSA total of 57 180 subjects for the consecutive 4-year birth cohorts were selected from the local children born between 2007 and 2010 in Yinzhou District, Ninghai County and Yuyao City. And they were followed up for varicella from 2008 to 2013. The recipients of the vaccinations were identified through Ningbo Immunization Information System and data on breakthrough infections among the recipients were collected by using China Information System for Disease Control and Prevention. The breakthrough varicella rate and the VE were calculated and the trends of them were described from 2008 to 2013 among 4-year birth cohorts. The cumulative incidence of varicella was compared between vaccinated and unvaccinated children among the consecutive 4-year birth cohorts.

RESULTSThe rate of varicella vaccine coverage, vaccine cumulative incidence among the cohorts was 96.74% (55 317/57 180) and 0.56% (321/57 180). The breakthrough varicella infection for 4-year birth cohorts was 0.44% (244/55 317), and for each birth cohort was 0.95% (142/14 928), 0.44% (61/13 855), 0.22% (29/13 433) and 0.09% (12/13 101), respectively. It was on the rise from 2008 to 2013 and the 2007 birth cohort of it increased fastest from 0.04% (6/14 928) in 2007 to 0.32% (48/14 834) in 2013. The vaccine cumulative incidence of these who vaccinated 1-dose varicella (the breakthrough varicella infection) was lower than these who were unvaccinated (the incidence: 6.25% (37/592), 3.52% (15/426), 3.69% (17/461) and 2.08% (8/384)) by each birth cohort (χ²= 130.27, P < 0.001 for 2007 birth cohort; χ²= 74.11, P < 0.001 for 2008 birth cohort; χ²= 162.80, P < 0.001 for 2009 birth cohort; χ²= 100.01, P < 0.001 for 2010 birth cohort). The vaccine effectiveness for 4-year birth cohorts was 89.33% (95% CI: 86.7%-92.1%) and for each birth corhort was 84.78% (95% CI: 77.94%-89.50%), 86.82% (95% CI: 77.82%-92.95%), 93.99% (95% CI: 89.27%-96.81%) and 95.60% (95% CI: 89.18%-98.21%), respectively. The effectiveness of each birth cohort declinedgradually from 2008 to 2013 and the 2009 birth cohort of it decreased fastest from 98.86% in 2010 to 66.83% in 2013.

CONCLUSIONSThe 1-dose varicella vaccine effectiveness was good, but breakthrough varicella infection rate was on the rise with time and the VE declined gradually from 2008 to 2013.

Background Research on the relationship between ambient temperature and preterm birth has received increasing attention, but the conclusions of the previous literature are inconsistent. Objective To explore the impact of environmental temperature exposure in Ningbo on premature delivery of pregnant women. Methods The birth information, preterm birth data, and age of pregnant women from January 2016 to September 2020 were collected by the electronic medical record system of Ningbo Women’s and Children’s Hospital. Meteorological data for the same period were obtained through Ningbo Meteorological Bureau, including daily average temperature, daily average relative humidity, and daily average air pressure. Daily concentrations of SO₂, NO₂, and PM₁₀ were derived through the air quality real-time release system on the website of Ningbo Environmental Protection Bureau. A distributed lag nonlinear model was used to analyze the impact of environmental temperature on preterm birth by stratifying pregnant women’s age and birth delivery mode. Results The incidence rate of preterm birth in Ningbo from 2016 to 2020 was 5.91%. The exposure-response curve between environmental temperature and preterm birth presented a “U” shape. Taking 22.5 ℃ as a reference, the cumulative effect of 31 ℃ (the 95th percentile) and 32 ℃ (the 99th percentile) over a 21-day lag on preterm delivery was statistically significant, and the related RR (95%CI) values were 1.67 (1.05-2.65) and 1.85 (1.09-3.14) respectively. The results of stratified analysis showed that among pregnant women ≥30 years old, the 21-day cumulative effects of 31 ℃ and 32 ℃ on preterm delivery were statistically significant, and the related RR (95%CI) values were 2.09 (1.08-4.05) and 2.36 (1.11-5.03) respectively; among pregnant women with natural delivery, the 21-day cumulative effect of 32 ℃ on preterm delivery was statistically significant, and the RR (95%CI) was 1.95 (1.02-3.74). Conclusion Exposure of pregnant women to high temperature during pregnancy could increase the risk of preterm birth, and there is a delayed cumulative effect.
