The therapeutic effect of acupuncture in treating the patients with urine retention after spinal and craniocerebral injuries was observed.Methods:Eighty patients with urine retention were divided into treatment group and control group.The patients in the treatment group were treated by puncturing Baliao (BL 31-34),Zhongii(CV 3) and Guanyuan (CV 4).The patients in the control group were treated by routine therapy of Western medicine.Resuits:In treatment group,33 cases were cured,5 cases got effectiveness and 2 cases had no effectiveness.In control group,25 cases were cured,7 cases got effectiveness and 8 cases had no effectiveness.Conclusion:The therapeutic effect of acupuncture was superior to that of routine therapy of Westem medicine in treating urine retention following spinal and craniocerebral injuries.

Objective To assess the left atrial early function in pilots with essential hypertension by strian rate imaging (SRI). Methods Twenty-five hypertensive pilots without left ventricular hypertrophy and expansion (LVN) were selected. Twenty-ifve healthy pilots were included as control group. At the left ventricular apical four-chamber view, three-chamber view, two-chamber view, the systolic, early and late diastolic peak strain rate (SRs, SRe, SRa) curves were acquired by SRI in the basal section, the middle section and the upper section of the wall of left atrium. The average strain rate (mSRs, mSRe, mSRa) was calculated. The LA maximal, minimal and pre-systolic volume (LAVmax , LAVmin and LAVp), LA passive ejection fraction (LAPEF), LA active ejection fraction (LAAEF) , left atrial stroke volume (LASV), E/A and E/E′ were calculated. Results The LAPEF, LAAEF, LASV, E/A, E/E′were (38.96±6.43)%, (61.11±5.86)%, (14.74±5.33)mm, 1.23±0.08, 8.63±1.77 in the control group, and were (34.18±5.72)%, (63.23±6.89)%, (10.12±3.23)mm, 1.04±0.26, 7.16±0.84 in the study group. Compared with the control group, signiifcant difference was detect in LAPEF, LAAEF, LASV, E/E′(t=4.840, 2.690, 4.801, 2.950, all P<0.05). No signiifcant difference was found in E/A between the study and control group (t=-1.424, P=0.178). There was signiifcant positive correlation between SRa and E/E′(r=0.632, P<0.05). Conclusion SRI could be applied in the evaluation of early left atrial function. In pilots with essential hypertension, the changes of strain rate in left atrial wall, which is prior to the modeling geometry of left ventricular, could be detected by SRI.

Objective: To investigate the effects of plateau environment exposure on the reproductive system of male rats, so as to provide the reference for mechanisms of reproductive damage in plateau environment. Methods: Sixty SPF-grade 12-week-old male Wistar rats were randomly divided into the plain-exposed group, the 1 day-, 3 day-, 7 day-, 14 day- and 28 day- plateau-exposed groups. The rats in the plain-exposed group were raised under normal conditions for 28 days, while the rats in the plateau-exposed groups were raised in a simulated high-altitude plateau chamber. After the completion of the designated feeding periods, the rats were sacrificed under anesthesia, and testicular tissue and abdominal aortic blood were collected to detect the testicular index and evaluate sperm quality. Histological and cellular morphologies of the testicular tissue were analyzed. Additionally, the levels of malondialdehyde (MDA), superoxide dismutase (SOD) and reactive oxygen (ROS) in the testicular tissue were determined, along with serum levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH) and testosterone (T). Conclusions Plateau environment may cause a decrease in testicular index and sperm quality, impair mitochondrial function, induce oxidative stress, and thus affect reproductive system of male rats. However, there are signs of self-repair in the reproductive system with the increase of exposure duration.

Objective:To investigate the prevalence of thyroid nodule in middle-aged and elderly people in Heilongjiang Province, and to analyze its epidemiological characteristics and influencing factors.Methods:From December 2017 to December 2018, middle-aged and elderly people aged 40-70 years old were recruited through probability proportional sampling (PPS) method for a cross-sectional survey. The respondents were stratified by age (40-49, 50-59, 60-70 years old), urine samples were collected at random once during the day, and urinary iodine was detected by arsenic-cerium catalytic spectrophotometry (WS/T 107.1-2016). At the same time, questionnaire surveys and thyroid ultrasound examinations were conducted on the respondents. Logistic regression was used to analyze the relationship between the related investigation factors and the thyroid nodule.Results:A total of 2 771 middle-aged and elderly people were included, and their age was (54.32 ± 8.24) years old. The median of urinary iodine was 157.04 μg/L, which was an iodine appropriate level. The prevalence of thyroid nodule was 43.63% (1 209/2 771), and the prevalence increased with age(χ 2trend=49.400, P < 0.01). The prevalence of thyroid nodule in females [46.98% (917/1 952)] was significantly higher than that in males [35.65% (292/819), χ 2=30.082, P < 0.01]. In patients with thyroid nodule, small nodule accounted for 57.65% (697/1 209), large nodule accounted for 42.35% (512/1 209), and the proportion of large nodule increased with age (χ 2trend=18.751, P<0.01). Solitary nodule accounted for 42.76% (517/1 209), multiple nodule accounted for 57.24% (692/1 209), and the proportion of multiple nodule increased with age(χ 2trend=18.437, P<0.01). Cystic-solid nodule was the most common[47.97%(580/1 209)], followed by solid nodule [44.25% (535/1 209)], and cystic nodule was the least common [7.78% (94/1 209)]. Logistic regression analysis showed female [odds ratio ( OR)=1.868, 95% confidence interval ( CI): 1.538-2.269, P < 0.01], age (50-59 years old: OR=1.258, 95% CI: 1.020-1.550, P < 0.05; 60-70 years old: OR=1.762, 95% CI: 1.407-2.207, P < 0.01), overweight ( OR=1.303, 95% CI: 1.078-1.574, P < 0.01), hypertension ( OR=1.332, 95% CI: 1.037-1.712, P < 0.05), and diabetes ( OR=1.604, 95% CI: 1.077-2.387, P < 0.05) were independent risk factors affecting the occurrence of thyroid nodule in middle-aged and elderly people. Conclusions:The epidemiological characteristics of thyroid nodule in middle-aged and elderly people in Heilongjiang Province have obvious age trends and gender differences. The proportion of large nodule and multiple nodule increase with age. Early screening and attention to the prognosis of women, older, overweight, hypertension and diabetes people should be strengthened.
