Objective To examine the change of body weight (BW) and blood pressure (BP) in obese rats, clarify relationships between BP and BW and other factors. Methods Male Spraque-Dawley rats were fed either with normal diet (ND) or high calorie diet (HC) for 20 weeks. BW and BP of tail artery were observed biweekly and tetraweekly respectively; serum leptin and fasting insulin (FINS) were detected by enzyme-linked immunoadsordent assay (ELISA) and radioimmunoassay (RIA) respectively. Fasting plasma glucose (FPG) and free fatty acid(FFA) were measured by conventional means. Results BW, abdominal fat weight (AFW), ratio of abdominal fat weight to body weight (RF/W), systolic blood pressure (SBP), diastolic blood pressure (DBP), serum levels of leptin and FINS, FPG, FFA increased in the HD group after 20 weeks diet intervention (P＜0.05 or P＜0.01). SBP was strongly correlated with BW, leptin, FINS and FFA (P＜0.05), DBP was correlated with FFA (r=0.47, P＜0.05). In addition, leptin was positively correlated with BW, AFW, RF/W, FINS and FFA (P＜0.05 or P＜0.01). Conclusion In this study of high calorie-diet induced rats, the gain of BW is accompanied by increased BP. The obese rats have hyperleptinemia, hyperinsulinemia, hyperglycemia and dyslipidemia which may have important effects on the development of obesity-related hypertension. RF/W is the key factor in which affect serum leptin level.

AIM: To compare the visual acuity and contrast sensitivity of eyes with different corneal spherical aberration implanted with the same aspherical IOL and evaluate the effect of different ocular spherical aberration on visual performance after phacoemulsification.
METHODS:It was a prospective case series study. Forty-six eyes of thirty-nine age-related cataract patients in our department were included. The patients were divided into 3 groups according to the value of preoperative corneal spherical aberration. Eyes with corneal spherical aberration≤0. 2μm were assigned to group A, those with corneal spherical aberration >0. 2μm and ≤0. 3μm to group B, and those with corneal spherical aberration≥ 0. 3μm to group C. All patients underwent phacoemulcification and recieved AcrySof IQ aspheric IOL. Uncorrected visual acuity ( UCVA ) , best-corrected visual acuity( BCVA) , contrast sensitivity, and total ocular higher - order aberrations for a 6. 0mm pupil were recorded 3mo postoperatively. ANOVA were used to analyze the data.
RESULTS: There were no significant differences in UCVA and BCVA between the 3 groups (P=0. 287, 0. 115). Contrast sensitivity was no statistically significant difference between the 3 groups at any spatial frequency under photopic、 mesopic, and mesopic with glare conditions (P>0. 05). With a 6. 0mm pupil diameter, root mean square values for total ocular higher - order aberrations were lower in groups A and B than that in group C (P=0. 000). The difference of total ocular spherical aberration was statistically significant between the 3 groups (P=0. 000). Coma and trefoil were similar between the groups (P=0. 788,0. 590), with no statistically significant differences.CONCLUSION:Implantation of the same aspherical IOL in eyes with different corneal spherical aberration results in similar visual acuity and contrast sensitivity. Small differences of ocular spherical aberration after phacoemulsification have no effect on visual performance.

Objective: To investigate the health-seeking delay in tuberculosis among school students in Yining City, Xinjiang Uygur Autonomous Region from 2009 to 2020, and analyze the influencing factors, so as to provide the evidence for reducing the health-seeking delay in tuberculosis among students in Yining City. Methods: The demographic features and diagnosis of students with tuberculosis in Yining City from 2009 to 2020 were retrieved from the Tuberculosis Management Information System of the Chinese Disease Control and Prevention Information System, and the factors affecting the health-seeking delay in tuberculosis were identified using the multivariable logistic regression analysis. Results: A total of 443 students with tuberculosis were reported in Yining City from 2009 to 2020, including 209 boys and 234 girls, with a male/female ratio of 1∶1.12. There were 29 primary school students ( 6.55% ), 81 junior high school students ( 18.28% ), 187 high school students ( 42.21% ) and 146 college students ( 32.96% ) reporting tuberculosis, and 394 cases ( 88.94% ) had locally registered residence. There were 287 students with health-seeking delay in tuberculosis ( 64.79% ), and the median duration of health-seeking delay was 35 ( interquartile range, 33 ) days. Multivariable logistic regression analysis showed that registered residence ( local, OR=1.899, 95%CI: 1.004-3.591 ) and origin of tuberculosis patients ( clinical consultation, OR=3.448, 95%CI: 1.755-6.775; recommendation for symptoms, OR=3.215, 95%CI: 1.161-8.900; tracking, OR=2.415, 95%CI: 1.269-4.596 ) and diagnostic results ( positive sputum smears, OR=3.081, 95%CI: 1.710-5.551 ) statistically correlated with health-seeking delay among students with tuberculosis. Conclusions The proportion of health-seeking delay in tuberculosis was high among students in Yining City from 2009 to 2020; registered residence, origin of tuberculosis patients and diagnostic results were associated.

Select patients diagnosed of hypertension in the first place in 16 hospitals and the patients were described by association rules analysis and distribution for the analysis in the study,in order to understand the information of diagnosis and treatment in hypertension patients in real world. The information include age, gender, admission condition, inpatient department, hospitalization expenses, western medicine comorbidities, the traditional Chinese medicine (TCM) syndrome and the medicine. The average age of patients was 64 years in the study. The proportion of men to women about 1. 10: 1. Admission condition is critical for about 10.12% of the total and more concentrated in the cardiovascular department. Hospital stay ranged from 8 to 14 d. Inpatients with medical insurance is 62.93%. Total hospitalization cost distribution most is the 5 000-10 000 RMB. Hypertension complicated with coronary heart disease, blood lipoprotein disorder disease; phlegm and blood stasis and Yin deficiency of liver and kidney are the most in TCM syndrome type. Promoting blood circulation and removing blood stasis is the major in Chinese medicine treatment. Western medicine treatment basically conforms to the guidelines. The most antihypertensive drugs is calcium antagonistst, accounting for about 81.2% of the total number. Class ACEI, class ARB, beta blockers, diuretics class are accounted for 43.0%, 43.4%, 42.4%, 42.4%, fixed compound is only 2 393, accounting for about 8%. the total frequency of five classes of antihypertensive drugs is 78 206 times. The principal conclusions of this analysis are as follows: the elderly people is the most in hypertension, more men than women; medical insurance is the majority type in hospitalization cost; nearly half of the population is combined with coronary heart disease; phlegm and blood stasis and yin deficiency of liver and kidney are the most in TCM syndrome type; western medicine treatment basically conforms to the guidelines. Combination therapy is more, less fixed compound preparation in western medicine. Chinese medicine is mainly to promoting blood circulation. Suggesting that the clinical treatment in strict blood pressure and at the same time, pay attention to combination therapy and the use of fixed compound preparation,it's useful to control the blood pressure better. Combined with traditional Chinese medicine and resolving phlegm and removing blood stasis, reduce the target organ damage, reduce complications, the prevention and control work of hypertension in China still faces enormous challenges at present. The result provides reference information for clinical medicine and medical research.

Objective To evaluate the effects of chronic arsenic poisoning on serum inhibin-B (INH-B) and testosterone of male rats.Methods Forty Sprague-Dawley rats in cleanliness grad were randomly divided into four groups according to body weight:high-dose,middle-dose,low-dose arsenic exposure groups and control group,10 animals in each group.Rats in high-dose,middle-dose,and low-dose groups were administered with arsenic in concentrations of 10.0,5.0,2.5,0.0 mg/kg in distilled water,respectively.Rats in control group were fed with distilled water freely.After 9 months,serum INH-B and testosterone were tested using an ELISA Kit.Results Serum INH-B and testosterone levels in the above mentioned four groups,respectively,were (66.31 ± 37.21),(75.13 ± 29.88),(119.02 ± 36.10),(133.04 ± 38.67)ng/L and (1.292 ± 0.715),(1.757 ± 0.649),(2.359 ± 0.675),(2.817 ± 0.890)μg/L,and the differences between different groups were statistically significant (F=84.88,8.214,all P ＜ 0.05).Serum INH-B and testosterone levels in high-dose and middle-dose groups were significantly lower than that of control group(all P＜ 0.05),whereas no significant difference was found between low-dose group and control group (all P ＞ 0.05).Conclusion Chronic arsenic poisoning has led to decreased concentration of serum INH-B and testosterone in male rats.

Objective To investigate the effects of sub-chronic arsenic poisoning on hyaluronidase activity of rat sperm.Methods Forty Sprague-Dawley (SD) rats in cleanliness grade,weighing 100-200 g,were randomly divided into four groups:control group,low-dose,middle-dose and high-dose arsenic exposure groups,10 in each group,and allotted to cages.Rats of arsenic groups were exposed to arsenic through drinking water (As2O3 was dissolved in distilled water).The concentrations of As2O3 in low-dose,middle-dose and high-dose groups were 25,50,and 100 mg/L,respectively.Body weight of each rat was weighed once a week.The rats in control group drank distilled water freely.All rats were fed for three months.After the experiment,all rats were killed and their sperms were collected.The positive rates and hyaluronidase activity intensities of the sperms in different groups were examined by the mature improved fixed-substrate film method.Results The positive rate of sperm hyaluronidase in control,low-dose,middle-dose and high-dose groups were (90.8 ± 13.2)％,(79.1 ± 15.6)％,(59.7 ± 20.3)％ and (33.8 ± 14.5)％,respectively.Compared with the control group,the positive rates of the middledose and the high-dose groups were significantly reduced(all P ＜ 0.05).The activity intensities of hyaluronidase in the sperms in control,low-dose,middle-dose and high-dose groups were (45.1 ± 24.0),(31.1 ± 21.3),(19.4 ± 15.3) and (9.8 ± 3.1)μm,respectively.Compared with the control group,the activity intensities of hyaluronidase of the middle-dose and the high-dose groups were significantly reduced(all P ＜ 0.05).Conclusion Sub-chronic arsenic poisoning reduces the activity intensities and positive rates of sperm hyaluronidase of rat,resulting in reduced sperm fertilizing capacity.

Objective To investigate the effects of subchronic arsenic exposure on caspase-3 expression in Leydig cells and serum testosterone level in rats. Methods Forty SD rats were divided into four groups based on body mass (160-220 g) by random number table, 10 in each group and treated with As2O3 through drinking water at the doses of 0.0 (distilled water), 2.0, 12.0 and 60.0 mg/L for 14 weeks. Blood sample from heart was collected, serum testosterone was measured by enzyme linked immunosorbent assay (ELISA); the testicular tissue of rats was taken, the expression of caspase-3 was assayed by immunohistochemical staining, and its average gray value was analyzed with image analysis software (Biomias). Results There were statistically significant differences of the serum testosterone levels between groups (F= 37.99, all P< 0.05). Compared with the control group [(3.082 3 ± 0.653 0) ng/L], serum testosterone levels in middle-dose and high-dose groups [(1.694 6 ± 0.255 4), (1.350 5 ± 0.281 9)ng/L] were significantly lower (all P< 0.05). The numbers of positive cells of caspase-3 were 8.10 ± 1.91, 9.80 ± 2.15,10.00 ± 1.83 and 10.90 ± 2.38 in each vision in the 4 groups, there were statistically significant differences between groups (F=3.17, all P<0.05), compared with the control group , the middle-dose and high-dose groups were significantly higher (all P<0.05);the average gray values of caspase-3 were 135.10 ± 6.89, 130.00 ± 3.30, 117.10 ± 4.28, and 113.10 ± 5.38, there were statistically significant differences between groups (F = 41.09, P < 0.05), compared with the control group, the middle-and high-dose groups were decreased (all P<0.05). Conclusions One possible mechanism of As2O3 on male germ cell toxicity may be through up-regulation of the expression of caspase-3 in Leydig cells of SD rats and initiating the pathway of the apoptosis signal, which can lead to increased apoptosis of Leydig cells, decreased concentrations of testosterone, and damaged reproductive function in rats.
