Objective To compare the clinical outcomes of Chinese rapamycin-eluting stents (Firebird stents) and imported paclitaxel-eluting stents ( Taxus stents ) in the treatment of acute myocardial infarction. Methods Ninety-seven patients with ST segment elevated acute myocardial infarction were treated with Firebird stents (in 51 patients) and Taxus stents (in 46 patients). The death rate, re-acute myocardial infarction, target lesion revascularization (TLR) ,and major adverse cardiac event (MACE) within 9 months after percutaneous coronary intervention ( PCI) were observed between the two groups. Results The rate of successful stent-implantation, angina,death, re-acute myocardial infarction, TLR and MACE was 100% ,9. 8% ,0% ,2. 0% ,0% , 11. 8% in the Firebird stent group and 100% ,8. 7% ,0% ,2. 2% ,0% ,0% and 10.9% in the Taxus stents group within 9 months after PCI. There was no significant difference between the two groups. Conclusions There is no significant difference in the clinical effect between the Firebird stent group and Taxus stent group within 9 months after PCI. However, the effect-cost ratio is better in the Firebird stent than the Taxus stent.

ObjectiveTo study the value of liquid-based cytology and colposcopy in screening for cervical lesion among urban community women of Beijing.MethodsA total of 795 women aged 20～54 years with sexual activity living in Zhanlanlu Community of Beijing were screened for cervical lesion Cervcal specimen was collected for thin-layer,liquid-based cytology test (LCT) from each of the participants in gynecologic examination.Colposcopy and biopsy were performed for the women with positive LCT.ResultsForty-five of 795 (5.7%) women were positive for LCT[≥ASC-US (atypical squamouscell of undetermined significance)],with 33 of ASC-us,eight of low-grade squamous intraepithelial lesion (LSIL),three of high-grade squamous intraepithelial lesion (HSIL),one of atypical glandular cells (AGC).Five of 45 women with positive LCT refused to accept colposcopy.Among 40 women with colposcopy and biopsy,chronic cervicitis was diagnosed in 11(27.5%),cervical condyloma acurninatum in 14(35.0%),cervical intraepithelial neoplasia (CIN) 1 in seven(17.5%),CIN 2 in three (7.5%),CIN 3 in four(10.0%),and early invasive cervical cancer in one(2.5%).In 750 women with negative LCT,cervical condyloma acuminature was diagnosed in two(0.3%),CIN 1 in five(0.7%)and low-grade glandular intraepithelial lesion (LGIL) bin one(0.1%).Sensitivity and specificity of LCT screening for cervical lesion(≥CIN 1)were 71.4%and 94.2%,respectively,with positive and negative predictive values of 37.5%and 99.2%.respectively,and those screening for cervical lesion more than CIN 2 were 100.0%, 96.0%,20.5%and 100.0%,respectively.ConclusionsMore attention should be paid to early screening for cervical lesion in urban community women.LCT combined with colposcopy and biopsy provide very helpful information in screening for early cervical cancer.

OBJECTIVETo test and vertify the clinical efficacy of Chinese syndrome-differentiation therapy in treating stable chronic obstructive pulmonary disease.

METHODTwo hundred and sixteen stable-COPD patients were randomly divided into 2 groups: the treated group and control group, they were treated with respiratory exercises increases Chinese medicine and respiratory exercises increases placebo for 4 weeks respectively. Then evaluate the health-related quality of life of patients with stable COPD by using SF-36 before and after treatment.

RESULTComparison of the health-related quality of life before and after treatment: the health-related quality of life in treated group was significantly improved after treatment and total score of SF-36 was better than control group (P < 0.05).

CONCLUSIONRespiratory exercises increases Chinese medicine could improve the health-related quality of life significantly in patients with stable COPD, moreover its efficacy was superior to respiratory exercises increases placebo.

OBJECTIVETo evaluate the value of colposcopical 4-quadrant biopsies for detecting precancerous lesion in cervical cancer screening.

METHODSWe used the data of a cross-sectional screening study in 1999, in which 1,997 women received cervical cancer screening in Xiang Yuan County, Shanxi province. The sensitivity, specificity and accuracy of both 4-quadrant biopsy and colposcopy directed biopsy to detect high-grade or more severe squamous intraepithelial lesions (HSIL+) were calculated.

RESULTS1,784(89.3%) women who received 4-quadrant biopsies and endocervical curettage were negative. 127(6.4%) women were diagnosed as LSIL, 74(3.7%) women as HSIL and 12(0.6%) cases of squamous cell carcinoma. 1,478(74.0%) women who received biopsies in the sites of abnormal lesions were negative, 463(23.2%) cases of LSIL, 41(2.1%) cases of HSIL, 15(0.8%) cases of squamous cell carcinoma. The positive rate was 26.0%(519/1,997) for colposcopy, and the coincidence rate was 73.7% with pathological diagnosis. Sensitivity and specificity were 81.4% and 76.5% of colposcopy for HSIL+. In total of 519 women were found to be with any abnormal colposcopic appearance. The consistency rate between 4-quadrant biopsies and suspicious lesion-directed biopsies was 96.3%. By suspicious lesion-directed biopsy alone, 14.8% cervical lesions were miss-diagnosed, of which 8.6%(5/58) cases of total HSIL and 24.1%(14/58) cases of all LSIL.

CONCLUSIONS4-quadrant biopsy can detect more HSIL+ lesions and is more accurate than suspicious lesion biopsy alone. As an important triage technique to detect cervical precancerous lesions, it can improve the detection rate of HSIL+ lesions in cervical cancer screening.

To conduct the association between vitamin B12 and mental health in children and adolescents. Five databases were searched for observational studies in any language reporting on mental health and vitamin B12 levels or intake in children and adolescents from inception to March 18, 2022. Two authors independently extracted data and assessed study quality. Qualitative and quantitative analysis of data were performed. The review was registered in the PROSPERO database (CRD42022345476). Fifty six studies containing 37,932 participants were identified in the review. Vitamin B12 levels were lower in participants with autism spectrum disorders (ASD) (standardized mean difference [SMD], −1.61;95% confidence interval [95% CI], −2.44 to −0.79; p ＜ 0.001), attention deficit hyperactivity disorders (SMD, −0.39; 95% CI, −0.78 to −0.00; p = 0.049) compared with control group. Vitamin B12 intake were lower in participants with ASDs (SMD, −0.86; 95% CI, −1.48 to −0.24; p = 0.006) compared with control group, but showed no difference between depression group (SMD, −0.06; 95% CI, −0.15 to 0.03; p = 0.17) and the control group. Higher vitamin B12 intake were associated with lower risk of depression (odds ratio [OR], 0.79; 95% CI, 0.63−0.98; p = 0.034) and behavioral problems (OR, 0.83; 95% CI, 0.69−0.99; p = 0.04). The vast majority of included studies supported potential positive influence of vitamin B12 on mental health, and vitamin B12 deficiency may be a reversible cause for some mental health disorders in children and adolescents.

OBJECTIVETo estimate the cost-effectiveness of esophageal cancer endoscopic screening once-in-a-lifetime and to predict the optimal screening age for people in high-risk areas of rural China.

METHODSA Markov model was constructed to predict and compare the effect of four esophageal cancer endoscopic screening modalities which varied with different screening ages. Long-term epidemiological effectiveness and cost-effectiveness were predicted by simulation of the model.

RESULTSCompared with the control group, strategies starting at 40, 45, 50 and 55 year-old had saved life-years of 629.51, 769.88, 738.98 and 533.21 years per 100 000 people, respectively, of which the strategy starting at 45 year-old saved the maximum life years. All strategies were cost-effective and starting at 40 year-old cost the most per life-year saved. Among all alternatives, strategies starting age at 45 year-old and 50 year-old were incremental cost-effective, and the incremental cost-effective ratios were 34 962.87 and 3 346.43 RMB per life year saved, respectively.

CONCLUSIONSThe strategy starting at 40 year-old implemented at present and other strategies were cost-effective in high-risk areas of rural China. However, the 45-year-old group is more aligned with the principle of cost-effectiveness. Considering the cost-effectiveness of different strategies and social economic status, 45 year-old is regarded as the optimal starting age of esophageal cancer once-in-a-lifetime endoscopic screening and is recommended in areas lacking health resources. The strategy of starting age at 40 year-old which could obtain better screening effects would be preferable in wealthy regions.
