Objective To test the efficacy and safety of nicergoline in treatment of vascular dementia patients with mild or moderate cognitive impairment. Methods A multicenter,double blind,randomized,efficient drug controlled clinical trial was carried out All the subjects met the DSM-Ⅲ criteria for vascular dementia We used MMSE and WMS as main assessing items and ADL,CGI as secondary assessing items. Results 103 subjects were assessed MMSE were raised in both groups after the treatment and more obvious in nicergoline group than in anecetan group (1 62?2 33 and 2 88?2 85 respectively) WMS raised in nicergoline group (5 04?10 61),but not in anecetan group (1 98?9 49) ADL and CGI (SI) showed decreased scores in both groups Total efficiency of nicergoline was 80 0% and of anecetan was 56 6%. Conclusions Nicergoline was an effective drug in treatment of vascular dementia and more effective than anecetan Using nicergoline 60 mg per day was safe

Objective:To evaluate the role of HPV16E6,cyclin D1,and human telomerase transcriptase(hTERT) in the development and progression of nasopharyngeal carcinoma(NPC) and to discuss the clinical significance.Methods: Immunohistochemistry was used to detect the expression of HPV16E6,cyclin D1,and hTERT in paraffin-embedded nasopharyngeal carcinoma tissues and nasopharyngeal chronic inflammation tissues.The relationship between their expression with the clinicopathological features of NPC was analyzed;the influence of their expression on prognoses of patients was also analyzed.Results: The positive rates of HPV16E6,cyclin D1,and hTERT in NPC tissues were 62.5%(35/56),50.0%(28/56),and 67.9%(38/56),respectively,which were significantly higher than those in the inflammation tissues(P0.05).HPV16E6 expression was positively correlated with cyclin D1(r=0.480,P

Objective To asses the effects of Gamma nail and DHS/Richard (dynamic hip screw) in the treatment of proximal femoral fractures. Methods A meta analysis of all the relevant randomized controlled trials (RCTs) was performed. We included randomized and quasi randomized controlled trials in patients with proximal femoral fracture to compare Gamma nail and DHS/Richard. Results First we identified 88 papers on comparison of Gamma nail and DHS/Richard in the treatment of proximal femoral fractures published from 1969 to 2003. 7 trials involving 1256 patients were identified as meeting all the eligibility criteria. 3 investigators independently graded study quality and abstracted relevant data, including information on mortality rates, wound infection, function, revision in patients with a proximal femoral fracture. 4 trials, which included a total of 621 patients, provided detailed information on mortality rates over the first 6 postoperative months. We found there was no significant difference in the relative risk of death in the first 6 months postoperative between treatments of Gamma nail and those of compression hip screw (relative risk 1.17;P=0.51). 6 trials that included a total of 1083 patients provided data on operative complications. The risk of operative complications from Gamma nail fixation appeared to be higher than that from compression screw and side plate fixation but not higher than that from compression hip screw (relative risk 1.41; P=0.02). We also found an obvious increase in the relative risk of fracture of femoral shaft between Gamma nail and compression hip screw (relative risk 6.99; P=0.00). Patients treated with Gamma nail had a higher rate of revision compared with those with compression hip screw, but there was no significant difference between the two groups (relative risk 1.85; P=0.20). In addition, wound infection, operative blood loss and functional recovery were similar between the tow groups(relative risk 0.98 for wound infection and 1.02 for function). Operating time for Gamma nail patients was significantly less than that for DHS/Richard ones (P

Objective: To understand the prevalence of major human parasitic diseases and related factors in Henan province. Methods: This stratified sampling survey was carried out according to the requirement of national survey protocol of major human parasitic diseases, 2014-2015. The prevalence of soil-transmitted helminths infection, taeniasis and intestinal protozoiasis were surveyed in 104 sites selected from 35 counties (districts) and the prevalence of clonorchiasis was surveyed in 62 sites selected from 37 townships. In each survey spot, 250 persons were surveyed. A total of 26 866 persons and 15 893 persons were surveyed. Modified Kato-Katz thick smear was used to detect the eggs of intestinal helminthes. Tube fecal culture was used to identify the species of hookworm. The Enterobius eggs were detected in children aged 3 to 6 years by using adhesive tape. The cyst and trophozoite of intestinal protozoa were examined with physiological saline direct smear method and iodine stain method. Results: The overall infestation rate of intestinal parasites was2.02% in Henan, and the worm infection rate was higher than protozoa infection rate. Fourteen kinds of intestinal parasites were found, including nematode (5 species), trematode (2 species), and protozoan (7 species). The infection rate of Enterobius vermicularis was highest, and Qinba Mountain ecological area had the highest infestation rate of intestinal parasites in 4 ecological areas of Henan. There was no significant difference in intestinal parasite infection rate between males and females (χ(2)=3.630, P=0.057), and the differences in intestinal parasite infection rate among different age groups had significance (χ(2)=124.783, P=0.000 1). The infection rate reached the peak in age group ≤9 years and the major parasite was Enterobius vermicularis. Furthermore the overall human infection rate of parasite showed a downward trend with the increase of educational level of the people (χ(2)=70.969, P=0.000 1), the differences had significance (χ(2)=120.118, P=0.000 1). For different populations, the infection rate of intestinal parasites was highest among preschool children. The infection of intestinal helminth was mainly mild, only 2 severe cases were detected. The infection rate of Clonorchis sinensis in urban residents was only 0.006%. Logistic regression analysis showed that being preschool children (χ(2)=15.765, P=0.000 1) and drinking well water (χ(2)=45.589, P=0.000 1) were the risk factors for intestinal parasite infection, and annual income per capita of farmers was the protective factor against intestinal parasite infection. The infection rates of protozoa and intestinal parasites decreased sharply compared with the results of previous two surveys, and the rate of intestinal helminth infection also dropped sharply compared with the second survey. The numbers of protozoa, helminth and intestinal parasites detected in this survey were all less than the numbers found in the previous two surveys. Conclusions: Compared the results of three surveys in Henan, the infection rate of protozoa and intestinal parasites showed a downward trend. The prevention and treatment of Enterobius vermicularis infection in children should be the key point of parasitic disease control in the future.

Background Nd: YAG laser posterior capsulotomy is an important way for after cataract.Usually the patient will use glucocorticoid eye drops to treat the anterior chamber inflammation after operation,but there is potential risk of elevating intraocular pressure (IOP).Objective This study was to compare the clinical effectiveness and safety of loteprednol etabonate ophthalmic suspension,tobramycin+ dexamethasone eye drops and fluorometholone eye drops following Nd: YAG laser posterior capsulotomy.Methods A randomized-controlled clinical trail was performed.One hundrcd and seventy-onc cycs of 127 paticnts who received Nd: YAG laser posterior capsulotomy for after cataract were randomly divided into four groups.Loteprednol etabonate ophthalmic suspension,fluorometholone eye drops,tobramycin+dexamethasone eye drops and systane eye drops was topically administered respectively in the four groups after laser posterior capsulotomy and 6 times per day for 5 days.IOP was measured with Goldmann tomometer 1 hour before operation and 1 hour,1 day,3 days and 7 days after operation.The ocular anterior segment inflammatory response was examined under the slit lamp and scored based on the Peizeng criteria.Written informed consent was obtained from each patient before any relevant medical procedure.Results The IOP was (18.2 ±4.7),(20.1 ±5.7),(18.7±5.5),(19.0 ±4.1),(19.5 ±3.5) mmHg in various time points in the loteprednol etabonate group; (18.7 ±5.3),(20.9±5.7),(21.3±4.5),(21.0±4.9),(22.5±6.5) mmHg in the fluorometholone eye drops group ; (17.9± 6.3),(20.3 ± 6.1),(23.0 ± 3.7),(24.7 ± 4.9),(24.5 ± 6.5) mmHg in the tobramycin +dexamethasone group and(18.4±6.3),(20.7±3.7),(22.7±6.5),(19.6±4.8),(18.5±3.5) mmHg in the systane group,showing a significant difference among the 4 groups (Fgroup =3.876,P =0.023).With the time lapse,the IOP was gradually reduced in the loteprednol etabonate group and systane group,but that in the fluorometholone group and tobramycin+dexamethasone group was elevated,showing a significant difference among them (Ftime =3.801,P =0.031).No any ocular and systemic adverse effect was found in various groups.The percentage of grade 1 and 2 of aqueous inflammatory cells was lower in the loteprednol etabonate group and tobramycin+dexamethasone group than the fluorometholone group and fluorometholone group and systane group(H =8.276,P =0.012).The percentage of Ⅰgrade of aqueous flare was 8％ in the loteprednol etabonate group,22％ in the fluorometholone group,18％ in the tobramycin+dexamethasone group and 30％ in the systane group,with a significant difference among them (H=9.305,P=0.000).Conclusions The use of corticosteroid eye drops can relieve the inflammatory response of ocular anterior chamber after Nd: YAG laser posterior capsulotomy.Loteprednol etabonate ophthalmic suspension has a better anti-inflammatory effect and less influence on IOP.

Abstract: Objective To investigate the willingness to receiving multitarget stool DNA (MT-sDNA) testing and factors affecting the payment among individuals receiving colonoscopy screening, so as to provide the evidence for the formulation and health economic evaluation of colorectal cancer screening strategies. Methods: Individuals at ages of 40 to 75 years that received colonoscopy screening in The Affiliated Hospital of Ningbo University Medical School from August 2021 to March 2022 were sampled. Participants' demographics, living behaviors, family history, willingness to receive MT-sDNA testing and willingness to pay for MT-sDNA testing were collected using questionnaire surveys, and factors affecting the willingness to receive and pay for MT-sDNA testing were analyzed using a multivariable logistic regression model. Results : A total of 546 respondents were enrolled, with a mean age of (56.25±8.66) years and including 282 men (51.65%). There were 504 respondents that were willing to receiving MT-sDNA testing (92.31%) and 480 that were willing to pay for the MT-sDNA testing (88.24%). Multivariable logistic regression analysis showed that a family history of colorectal cancer in first-degree relatives (OR=0.246, 95%CI: 0.068-0.888), history of hemorrhoids (OR=0.300, 95%CI: 0.109-0.826) resulted in low willingness to receive MT-sDNA testing, and recognizing the reliability of MT-sDNA testing (OR=5.749, 95%CI: 1.480-22.323), considering no difficulty in sampling for MT-sDNA testing (OR=32.042, 95%CI: 6.666-154.021) and considering a difficulty in sampling for MT-sDNA testing (OR=20.278, 95%CI: 4.405-93.354) resulted in high willingness to receive MT-sDNA testing, while recognizing the reliability of MT-sDNA testing (OR=5.003, 95%CI: 1.761-14.216), concern about the reliability of MT-sDNA testing (OR=4.166, 95%CI: 1.285-13.501), considering no difficulty in sampling for MT-sDNA testing (OR=6.558, 95%CI: 2.105-20.428) and considering a difficulty in sampling for MT-sDNA testing (OR=5.820, 95%CI: 1.810-18.720) resulted in high willingness to pay for the MT-sDNA testing among individuals receiving colonoscopy screening. Conclusion A family history of colorectal cancer in first-degree relatives, history of hemorrhoids and awareness of MT-sDNA testing are factors affecting the willingness to receive and pay for the MT-sDNA testing among individuals receiving colonoscopy screening.

Objective: To investigate the activities of daily living and the use of assistive devices among disabled people demanding assistive devices in Jiading Township, Jiading District, Shanghai Municipality, so as to provide the evidence for the implementation of rehabilitation interventions and the selection of assistive devices for the disabled people living in the community. Methods: The disabled people demanding assistive devices were sampled from 17 communities in Jiading Township in January 2020. A face-to-face questionnaire survey was conducted to collect participants'age, gender, type of disability, provision and use of assistive devices. The activities of daily living were evaluated using the Activities of Daily Living Scale, and the difference in the frequency of assistive device use was compared among the disabled people with different activities of daily living. Results: A total of 377 questionnaires were allocated, and 328 valid questionnaires were recovered, with an effective recovery rate of 87.00%. The respondents included 187 men ( 57.01% ) and 141 women (42.99%), and had a mean age of ( 71.78±13.86 ) years. Among all respondents, limb disability was predominant (248 people, 75.61%), and 84.45% (277 people) were provided with assistive devices. Assessment of activities of daily living showed complete self-care in 85 respondents ( 25.91% ), functional decline in 39 respondents ( 11.89% ) and functional dysfunction in 204 respondents ( 62.20% ). The proportion of functional dysfunction was predominantly detected among disabled people at ages of 80 years and older ( 79.63% ) ( P<0.05 ). Of the disabled people with assistive devices, 139 people used the devices daily ( 50.18% ), and the proportion of daily use of assistive devices was significantly higher in people with functional dysfunctions than in those with complete self-care ( 59.33% vs. 29.41%; P<0.05 ). In addition, no need was identified as the predominant cause of non-provision of assistive devices ( 29 people, 56.86% ). Conclusions Functional dysfunction of daily living is highly prevalent among the disabled people demanding assistive devices in Jiading Township, in whom the elderly are predominant, and the proportion of assistive device use is high among people with functional dysfunctions. The provision of assistive devices recommends to be improved based on assessment of activities of daily living.

In order to study the association of each item of a health examination and lifestyles with health-related quality of life (HRQoL), a cross-sectional survey by a self-administered questionnaire using the 12-Item Short Form Health Survey (SF-12, version 1) was conducted on 145 government managers that took health examinations in Tongji Hospital, Wuhan, China during 2005. The results showed that the determinations of organic functions including BMI, hemoglobin, blood platelet count,urine protein, urine WBC and lipid metabolism (LDL) were associated with HRQoL. The lifestyle items including age, sex, life satisfaction, drinking alcohol and kind of alcohol drunk, drinking tea,sleep quality and adhering to bedtime, working overtime, work stress were associated with HRQoL in the multiple regression models. Sex, age and life satisfaction were the lifestyle items most closely associated with HRQoL, while LDL, hemoglobin and urine protein were the health examination items most closely associated HRQoL. This study revealed that both lifestyle and health examination items were associated with HRQoL.
