Objective To observe the therapeutic effect of anti-inflammatory combined with cedilanid and diuretic therapy for treatment of patients with senile pneumonia and lung cancer accompanied by pleural effusion and to investigate the changes of concentrations in plasma levels of B-type natriuretic peptide(BNP)and C-reactive protein(CRP),procalcitonin(PCT)before and after treatment. Methods From July 2012 to January 2013, a prospective study was carried out to investigate 57 emergently hospitalized patients with pleural effusion,and according to the etiology,they were divided into two groups:a senile pneumonia group(30 cases)and a lung cancer group(27 cases). The same therapeutic measures were taken in the two groups,such as anti-infection,enhancement of cardiac function,diuresis,and limitation of the amount of liquid intake. Respectively,all the patients took the CT scan of the chest before treatment and on the 7th day after treatment,and at the same time,plasma concentrations of BNP,CRP and PCT were detected. Results ①According to the gradation of the New York Heart Association (NYHA),before treatment most of the cardiac function of patients in pneumonia group was at the Ⅲ grade,while that in the lung cancer group was at theⅠgrade,and the incidence of congestive heart failure(CHF)in pneumonia group was significantly higher than that in lung cancer group(86.7% vs. 14.8%,P<0.01). Before treatment,the plasma BNP level in pneumonia group was obviously higher than that in lung cancer group(ng/L:582.67±126.53 vs. 146.27±43.77,P<0.01);compared with that before treatment,BNP was significantly decreased in the pneumonia group(ng/L:225.59±131.33,P<0.05)after treatment,but no such obvious change in the lung cancer group(ng/L:149.34±51.05)was seen. The therapeutic effect of pleural effusion in the pneumonia group was markedly better than that in lung cancer group〔cure:70.0%(21 cases)vs. 0(0),P<0.01〕. ②Before treatment,the plasma levels of CRP and PCT in pneumonia group were remarkably lower than those in lung cancer group(both P<0.05);after treatment,CRP and PCT levels were decreased or decreased to close to the normal physiological range in patients of the two groups,but the comparisons between the two groups there were no statistically significant differences〔CRP(mg/L):20.21±16.32 vs. 22.76±18.53,PCT(ng/L):0.46±0.13 vs. 0.55±0.17,both P>0.05〕. Anti-inflammatory effect in pneumonia group was much superior to that in lung cancer group〔basically cured:86.7%(26 cases)vs. 0(0),P<0.05〕. In pneumonia group,the decrease of the above two indexes after treatment was consistent with the pneumonia shadow dissipation,while in the lung cancer group,no such consistency was found,apparently,the latter phenomenon was associated with the tumor invasive occupation. Conclusion To detect the concentration changes of plasma BNP, CRP and PCT has important clinical significance in screening the cardiac insufficiency and evaluating the curative effect of anti-inflammatory combined with cedilanid and diuretic therapy in patients of lung diseases complicated by pleural effusion.

OBJECTIVETo study the economic burden caused by occupational chronic n-hexane poisoning.

Objective:To investigate status quo of social support and social function in homeless schizophrenics.Methods:A total of 468 schizophrenics who received treatment in Hangzhou Seventh People's Hospital from January 2018 to December 2019 were included in this study. They were divided into homeless group ( n = 310) and non-homeless group ( n = 158) according to whether they had homeless behaviors. The basic information of admitted patients, level of social support and disease severity were surveyed among admitted patients using self-made questionnaire regarding basic information of admitted patients, Social Support Rating Scale, and Brief Psychiatric Rating Scale. Results:The numbers of schizophrenics in the aspects including male gender, rural household registration, non-local residents, no occupation, unmarried status, low level education, and age at 30-50 years in the homeless group were significantly higher than those in the non-homeless group ( χ2 = 3.58, 20.14, 18.69, 46.29, 33.16, 24.38, 29.75, all P < 0.05). The score for each SSRS domain and total score in the homeless group were significantly lower than those in the non-homeless group [(15.35 ± 5.42) points, (4.34 ± 2.78) points, (6.48 ± 1.89) points, (26.23 ± 7.35) points; (18.99 ± 3.78) points, (6.35 ± 3.23) points, (7.82 ± 2.01) points, (32.59 ± 7.02) points, t = 6.34, 10.52, 12.83, 14.68, all P < 0.001]. The score for each BPRS domain and total score in the homeless group were significantly higher than those in the non-homeless group [(19.35 ± 5.85) points, (22.58 ± 2.73) points, (18.74 ± 2.46) points, (18.48 ± 0.25) points, (16.38 ± 3.12) points, (79.43 ± 3.64) points; (12.92 ± 4.23) points, (16.24 ± 3.66) points, (16.97 ± 3.77) points, (10.58 ± 3.34) points, (6.36 ± 4.23) points, (62.72 ± 2.57) points, t = 9.92, 7.02, 6.33, 10.35, 15.74, 28.46, all P < 0.001]. Conclusion:The poor individual condition and low level of social support in patients with schizophrenia are important factors that cause homelessness.

Objective:To explore the average age at onset of endometrial cancer (EC) and the differences between domestic and international factors.Methods:Pubmed, Wanfang Database, VIP Information Resource System, and China National Knowledge Infrastructure (CNKI) were selected to extract clinical research data related to EC. Through data mining methods such as frequency analysis and cluster analysis, we compared the differences in the average age of onset of EC between domestic and foreign countries.Results:A total of 280 articles that met the inclusion criteria were selected, and frequency analysis found that the average age of onset of EC in the Chinese population was mostly concentrated under 57 years old, while in European and American countries, it was mainly concentrated above 57 years old. Through cluster analysis, it was found that the average age of onset in China was clustered in one category with most Asian countries, while European and American countries and Australian countries were clustered in another category. Through analysis of domestic and foreign articles, it was found that the average age of onset of EC did not show a significant upward or downward trend with years.Conclusions:There are differences in the average onset age of EC among different countries and regions. The onset age of EC in Asian populations is significantly earlier than that in European and American populations. The average onset age of EC in Chinese populations is 54 years old, and there is no trend towards a younger onset of EC.

Objective To detect the expressions of peroxisome proliferator-activated receptor (PPAR) isotypes (PPARα,PPARβ/δ and PPARγ) in migraine rat models induced by nitroglycerin and their roles in morbidity mechanism.Methods Forty-eight SD rats were randomly divided into normal control group,physiological saline control group and migraine model group (n=16).The rat migraine models were established according to Tassorelli Cristina method and performed abdominal subcutaneous injection of nitroglycerin at a dosage of 9.5 mg/kg; rats in the physiological saline control group were given the same volume of physiological saline and that in the normal control group did not receive any treatment.The trigeminocervical complexes were separated from rats in each group.Expressions of PPARα,PPARβ/δ and PPARγ were detected by Western blotting and immunohistochemical method.Results Immunohistochemical staining showed strong positive expressions of PPARα,PPARβ/δ and PPARγ in model group,which were higher than those in normal control group and physiological saline control group.Western blotting indicated that the expressions of PPARα,PPARβ/δ and PPARγγof the trigeminocervical complexes in model group were 0.361 ±0.051,0.372 ±0.061 and 0.654 ±0.101,respectively,which were also significantly higher than those in normal control group and physiological saline control group (P＜0.05).Conclusions The expressions of PPARα,PPARβ/δ and PPARγγin the trigeminocervical complexes in migraine rats are increased,which might be a compensatory neuroprotective response in the occurrence of migraine.

OBJECTIVETo investigate the effects of rs10916581, a common single nucleotide polymorphism (SNP) located in the promoter region of pre-miR-320b-2, on coronary heart disease (CHD) risk and circulating microRNA-320b (miR-320b) level. To explore potential factors influencing circulating miR-320b level.

METHODSRs10916581 was genotyped in a case-control study with 1 507 CHD cases and 1 379 age- and sex-frequency-matched controls. The cases were consecutively recruited from 3 hospitals (Tongji Hospital, Union Hospital, and Wugang Hospital) in Wuhan city (Hubei, China) between May 2004 and October 2009 and all the controls resided in Wuhan communities. A subgroup of 174 CHD cases and 181 non-diabetes controls without acute infection were randomly selected and their circulating miR-320b levels were detected using quantitative reverse transcriptase polymerase chain reaction assays. The association of rs10916581 with CHD susceptibility was analyzed with multivariable logistic regression model. Generalized linear regression model was used to explore the associations of rs10916581 and some other factors with circulating miR-320b level.

RESULTSIn single-factor logistic regression analysis, no association was found between rs10916581 and CHD risk. After adjustment for age, sex, BMI, smoking status, hypertension, diabetes, total triglyceride, total cholesterol/high density lipoprotein (TC/HDL-C), the result did not materially alter(compared with CC genotype, the OR (95%CI) of CHR in the subjects carried CT, TT, CT+TT genotypes were 0.94 (0.76-1.15), 0.99 (0.74-1.33) and 0.95 (0.78-1.16) ). No significant interactions were observed between the conventional risk factors of CHD (age, gender, smoking status, BMI, hypertension, diabetes, CHD family history) and rs10916581 on CHD risk (P > 0.05). Rs10916581 showed no significant association with circulating miR-320b level in cases, controls or total population (β(95%CI) was -0.028 (-0.495-0.440), 0.250 (-0.226-0.727) and 0.134 (-0.218-0.486) respectively, P > 0.05). However, circulating miR-320b level was negatively associated with BMI (β (95%CI) was -0.140 (-0.261--0.020), P = 0.022) while positively associated with TC/HDL(β (95%CI) was 0.620 (0.261-0.979), P = 0.001) in cases, and in total population, its circulating level tended to be lower in diabetes or hypertension patients (β(95%CI) was -1.025 (-1.696--0.354) and -0.594 (-1.138--0.049) respectively, P = 0.003, 0.033 respectively) and was positively associated with TC/HDL-C (β(95%CI) was 0.108 (0.027-0.190), P = 0.009).

CONCLUSIONThe common SNP (rs10916581) in the promoter region of pre-miR-320b-2 might have little contribution to the CHD predisposition in Chinese Han population, and it might not affect circulating miR-320b level. Conventional CHD risk factors (BMI, TC/HDL-C, hypertension and diabetes) might have effects on its circulating level.
