Objective To evaluate the semen quality of potential semen donors of college students and investigate their reproductive health status. Methods According to the screening procedure in the Basic Standard and the Technical Norms of Human Sperm Bank revised by Chinese Ministry of Health in 2003,all sperm samples of 355 potential donors were examined. Results 37 of 355 donors sperm(10.4%) were qualified to the normal standard revised by Chinese Ministry of Health;and the rest(89.6%) were abandoned,because the sperm numbers of 267 donors were not reached the identified semen standard of the human sperm bank in the first screen,26 donors(7.4%)were with abnormal health status,4 donors did not ejaculate and got samples,9 donors with normal semen quality did not take physical health examination,the normal shape percentage of 6 donors sperm was lower than 30% and the thawed revival percentage with(a+b) grade of 6 donors was lower than 60%.135 of 355 donors(38.0%) sperm quality were qualified to the male productive standard of WHO. Conclusion The results indicated that the sperm quality of undergraduate declines and the society should pay more attention to the reproductive health of college students.

Objective: To explore the value of body measurement indicators in screening for metabolic syndrome (MS), so as to provide the basis for early detection and prevention of MS. Methods: The individuals who were 18 years old or above and underwent physical examinations at a tertiary hospital of Xinjiang Uygur Autonomous Region were selected using the convenience sampling method. Demographic information, lifestyle, waist circumference (WC) and blood biochemical indicators were collected through questionnaire surveys, physical examinations and laboratory tests. The associations of WC, waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), body roundness index (BRI), abdominal volume index (AVI), lipid accumulation product (LAP) and visceral adiposity index (VAI) with MS were analyzed using a multivariable logistic regression model. The screening values of these body measurement indicators for MS were assessed by receiver operating characteristic (ROC) curves. Results: A total of 37 921 individuals were recruited, including 20 666 males (54.50%) and 17 255 females (45.50%), and had a median age of 41.00 (interquartile range, 20.00) years. There were 7 988 cases of MS, with a detection rate of 21.06%. Multivariable logistic regression analysis showed that WC, WHR, LAP and VAI were statistically associated with MS (all P<0.05), and the risk of MS increased with the levels of these indicators (all Ptrend<0.05), after adjusting for confounding factors (gender, age, lifestyle, etc.). The area under the ROC curve (AUC) of LAP for screening MS was the highest among single indicators, at 0.930 (95%CI: 0.927-0.933), and the optimal cut-off value was 43.13, Youden's index was 0.720, the sensitivity was 88.01%, and the specificity was 84.04%. The combined indicators of WC×VAI for screening MS had the highest AUC, which was 0.937 (95%CI: 0.935-0.939), and the optimal cut-off value was 0.17, Youden's index was 0.730, the sensitivity was 91.88%, and the specificity was 81.07%. The DeLong test showed that the AUC of WC×VAI for screening MS was higher than that of WC, WHR, LAP and VAI, respectively (all P<0.05). Conclusion The value of combining WC and VAI for screening MS is higher than other body measurement indicators.

Objective To explore the effect of shengmai injection (a Chinese herb preparation made from radix astragali and radix rehmanniae) on restoration of spontaneous circulation (ROSC) and hemodynamics in the early stage of resuscitation (CPR) in animal models of cardiac arrest, providing adjuvant support to stabilize the circulation for the facilitation of follow-up study in the resuscitated animal. Method A total of 30 rabbits were randomly(random number) divided into two groups, shengmai group and saline group, ( n = 15 in each group).Asphyxia method was used to establish animal models of cardiac arrest. In the shengmai group, 2 mL/kg shengmai injection was given immediately just after initiation of CPR and the same dose of shengmai injectio was given once again 10 minutes after ROSC. In the saline group, saline was administered in the same volume and at the same given time instead of shengmai injectio. The duration of cardiac arrest of rabbits, and the lengths of time consumed for ROSC and for resume of spontaneous respiration after CPR as well as the rate of ROSC obtained and 6-hours survival rate after CPR were documented. The changes of hemodynamics including LVSP, + dp/dtmax,- dp/dtmax, LVEDP were recorded before asphyxia,just after the emergence of ROSC and 30 min,60 min, and 120 min after ROSC. Results There were no significant differences in duration of cardiac arrest, length of time consumed for the resume of spontaneous respiration, rate of ROSC obtained and 6-hours survival rate between two groups (P ＞ 0.05), but the ROSC emerged sooner in shengmai group. The LVSP, + dp/dtmax and- dp/dtmaxsignificantly lower 30 min, 60 min and 120 min after ROSC then those before asphyxia in both groups, but LVEDP increased after ROSC (P ＜0.05). At the corresponding intervals after ROSC, the values of LVSP, + dp/dtmaxand - dp/dtmax in the shengmai group were higher than those in the saline group, and the values of LVEDP in the shengmai group were lower than those in the saline group ( P ＜ 0. 05). Conclusions Shengmai injectio used in rabbits with cardiac arrest can shorten the time consumed for ROSC after CPR, improve cardiac diastolic and systolic function after R OSC, stabilizing the hemodynamics after resuscitation.

Objective To analyze the clinical and pathological characteristics of thyroid nodules.Methods A retrospective analysis of the clinical data of 2843 Han patients with thyroid nodules from January 2009 to June 2011 in Henan province was performed.Results The most high-risk of thyroid nodule resided in the group aged 45-54.The main pathological manifestation was simple nodular goiter.The rate of preoperative misdiagnosis was 2.4％.22.1％ of the patients with thyroid nodules showed abnormal thyroid function,which was mainly as subclinical thyroid dysfunction.The positive rate of thyroid peroxidase antibody (TPOAb) in patients with thyroid nodule was 19.8％ while that of thyroid globulin antibody (TgAb) was 20.0％.Among all 2843 subjects,the prevalence of differentiated thyroid carcinoma (DTC) was 28.8％,and the incidence of DTC was accompanied by raised TSH levels.The prevalence of DTC exceeded 40％ in patients aged between 25 to 34 as well as more than 74 years old.The prevalence of DTC was up to 33.8％ in TgAb positive patients.There was no difference in TPOAb levels between DTC patients and non DTC patients (P =0.406),but the TgAb level in patients with DTC was significantly higher than that of non DTC patients (P =0.033).Conclusion Thyroid nodule patients aged 25-34 or older than 74 formed high-risk groups of DTC.The serum TSH level and TgAb level were positively correlated with the risk of DTC.

Objective To explore the effect of decoction of four-drug juice plus glutamine on nutritional support in the elderly critically ill patients. Methods One hundred and twenty-four elderly critical ill patients in The First Hospital of Jilin University from May 2010 to May 2012 were randomly divided into treatment group(n = 62)and control group(n = 62). Patients in both two groups were given enteral nutrition(EN)plus parenteral nutrition(PN)after the hemodynamics became stable. In addition,patients in control group were given routine EN + PN,while in treatment group was given decoction o four-drug juice + EN plus glutamine + PN. Prealbumin (PA),serum total protein( TP),transferrin( TF)and serum albumin( ALB)were detected before and after treatment of nutritional support. The informations including recovery of bowel sounds,the occurrence of complications,antibiotic use time and the duration of ICU stay were recorded. Results There were no significant differences between two groups in terms of nutrition indices before treatment(P > 0. 05). After treatment,the contents of pre albumin,transferrin,total serum protein,serum albumin in treatment group were( 145. 24 ± 6. 72)g/ L,(1. 93 ± 0. 98)g/ L,(79. 86 ± 10. 38)g/ L,(54. 91 ± 2. 91)g/ L respectively,better than those in control groups((139. 24 ± 38. 76),(1. 68 ± 0. 33),(74. 73 ± 7. 31),(49. 87 ± 2. 61)g/ L),and the differences were statistically significant( t = 3. 610,2. 929,4. 360,6. 767;P < 0. 05). The incidence of stress ulcer and double infection in treatment group were 42%(26 / 62),37%(23 / 62),significantly lower than the control group(59%(37 / 62),53%(33 / 62)),and the differences were statistically significant( χ2 = 5. 186, 5. 271,P < 0. 05). Antibiotic use time and the duration of ICU stay in treatment group were(8. 82 ± 0. 71)d and(16. 14 ± 3. 01)d,and reaching full eternal nutrition time was(6. 90 ± 1. 01)d,decreased less than that in control group((10. 21 ± 1. 30),(20. 67 ± 2. 29),(13. 91 ± 1. 51)d)and the differences were statistically significant(t = 8. 892,7. 786,3. 609,P < 0. 05). The average recovery time of bowel sounds and first anal exhaust time average in treatment group were(26. 8 ± 3. 6)h,(25. 4 ± 3. 2)h,lower than that in control group ((38. 4 ± 4. 8)h,(37. 6 ± 4. 9)h)and the differences were statistically significant( t = 3. 551,2. 516,P< 0. 05). Conclusion The application of decoction of four-drug juice plus glutamine on nutritional support of the elderly critically ill patients can reduce complications,shorten the duration of ICU,recover the intestinal function as soon as possible. Meanwhile,patients can transit to full eternal nutrition as soon as possible,then the cost of therapy is reduced and rehabilitation is quickly.

ObjectiveTo investigate the relevant factors influencing the incidence and mortality of post cardiac arrest syndrome (PCAS), and to provide the basis of improvement of resuscitation rate.Methods A single center retrospective study of cardiopulmonary resuscitation (CPR) according to Utstein model was conducted. A clinical case report form was designed to collect clinical data. The clinical data of patients whose spontaneous circulation was restored (ROSC)> 24 hours in intensive care unit (ICU) of the First Hospital of Jilin University from January 2008 to June 2014 were collected and analyzed. The relevant risk factors of the incidence and mortality rate of PCAS were screened and analyzed by multivariate logistic regression analysis.Results① Successful CPR was achieved in 93 patients, of whom 83 patients were shown to have systemic inflammatory response syndrome (SIRS), and 75 patients suffered from PCAS (80.65%). Among them 49 died, and 18 patients who did not suffer from PCAS survived.② The age, gender, history of previous chronic disease, site of occurrence of cardiac arrest, type of rhythm when cardiac arrest occurred, and dosage of adrenaline showed no significant influence on the incidence of PCAS. The incidence of PCAS was elevated when defibrillation was done more than 3 times (χ2= 10.806,P= 0.001), SIRS occurred after ROSC (χ2= 46.687,P< 0.001), interval between collapse and first defibrillation over 5 minutes (χ2 = 6.429,P = 0.011), interval between collapse and CPR longer than 5 minutes (χ2 = 4.638,P = 0.031), interval between collapse and administration of first resuscitation medication> 5 minutes (χ2 = 4.190,P = 0.041), and ROSC time was longer than 10 minutes (χ2 = 20.042,P< 0.001). Bivariate correlation showed that interval between collapse and CPR, interval between collapse and administration of first resuscitation medications, and ROSC time were all correlated (r1 = 0.677,r2 = 0.481,r3 = 0.617, allP< 0.001).③ There were no significant relations between the prognosis of PCAS patients and times of defibrillation, the amount of adrenaline used, and interval between collapse and first defibrillation. The mortality rate of PCAS was relatively elevated when interval between collapse and CRP was longer than 5 minutes (χ2 = 10.792,P = 0.001), interval between collapse and administration of first resuscitation medications was longer than 5 minutes (χ2 = 13.841,P< 0.001), ROSC time> 10 minutes (χ2 = 36.451,P< 0.001), the number of dysfunction organ≥ 4 (χ2 = 28.287,P< 0.001), arterial blood lactate levels> 2 mmol/L (χ2 = 28.926, P< 0.001), and acute physiology and chronic health evaluationⅡ (APACHEⅡ) score> 15 (χ2 = 33.558,P< 0.001). Multivariate logistic regression analysis showed that the risk factors affecting the prognosis were ROSC time [odds ratio (OR) after adjustment = 36.643, 95% confidence interval (95%CI) = 2.382-563.767,P = 0.010], the number of organs with dysfunction (OR = 9.010, 95%CI = 1.140-71.199,P = 0.037), and APACHEⅡ score (OR = 10.001, 95%CI =1.336-74.893,P = 0.025).Conclusions ROSC time, the number of organs with dysfunction, and APACHEⅡ score were independent predictors of PCAS prognosis. Efforts should be given to shorten the rescue time, to shorten the time for restoring the spontaneous circulation, to prevent and treat SIRS after ROSC, and to protect the function of organs, in order to improve the prognosis of patients with PCAS.
